    The invention relates to a feeding device, in particular a changing device, for feeding a bending press with bending tools and / or for exchanging one or more bending tools used in a bending press, comprising a tool store having at least two, preferably a plurality of guide rails for holding and guiding bending tools and at least one first transfer means for displacing the bending tools along a guide rail. The invention also relates to a method for feeding a bending press with at least one first bending tool from a tool store of a loading device.
    CH668035A5 discloses a bending press and a mechanism for changing bending tools. Bending tools are suspended in a storage device in each case on a hook. The change takes place by means of a support arm rotatable about a horizontal pivot axis, which receives a single bending tool and transfers it from the tool store into the bending press. A disadvantage of this changing device is that a lot of space must be made available for the movement of the support arm. In addition, the approach and pivoting of the arm in the direction of the tool holder of the bending press requires a complex sequence of movements. In addition, there is a high risk of collision between the support arm and parts of the bending press on the one hand and the tool storage on the other. A large amount of time when changing is also due to the fact that the bending tools only individually, i. can be transferred one after the other.
    EP2143506B1 discloses a device for exchanging and assembling a multi-part tool for a press brake. A complex and space demanding transfer device with a gripper or hook takes bending tools from the tool storage and spends them in the bending press. The transfer device is vertically and horizontally movable for this purpose; the hook can be rotated additionally.
    The resulting from the prior art disadvantages are particularly in the complex and space-demanding design of the tool storage and the transfer device, which transfers the bending tools from the tool storage in the bending press. In addition, the storage capacity of the tool memory is very limited or requires such a tool memory very much space. This results in particular from the fact that (as in CH668035A5) a separate holding structure, e.g. in the form of a hook, is required or that (as in both publications mentioned above) the tool memory must have sufficient (intermediate) space for the retraction of the transfer device. Changing tools can be time consuming. In addition to an increased risk of collision of the moving parts, in particular the transfer device, the cost is an adverse factor of the known devices.
    The object of the invention is to eliminate or mitigate these disadvantages and to provide a feeder which can be dimensioned to save space and whose tool storage has a higher storage density, i. can accommodate a higher number of bending tools per room unit. The loading and changing of bending tools should be accomplished in a simple and reliable way. The risk of collisions should be reduced, preferably completely eliminated. The charging device and its operation should be cheaper.
    This object is achieved with a loading device of the type mentioned by a clipboard with at least one guide rail for holding and guiding bending tools, wherein the tool storage and the clipboard are movable relative to each other and wherein at least one guide rail of the clipboard in various relative positions of factory zeugspeicher and clipboard each in alignment with another guide rail of the tool storage in alignment.
    With the feeding device according to the invention, it is possible to accommodate a plurality of bending tools in a guide rail in a row one behind the other, whereby the storage density of the tool storage is increased. In order to extract or separate a first bending tool from this row, bending tools can be temporarily moved to the clipboard and stored there (temporarily). In addition, the clipboard allows bending tools to be moved from one (or first) guide rail of the tool store to another (or second) guide rail of the tool store. Such shunting operations are carried out exclusively by shifting operations of bending tools along guide rails and relative movement (s) between the clipboard and tool storage.
    The great advantage of the invention is that the bending tools remain uninterrupted in guide rails during the maneuvering maneuver (i.e., do not have to be removed from the guide rails). The transfer of a bending tool from a guide rail (eg the tool storage) into another guide rail (eg the clipboard) is accomplished by bringing the two guide rails into alignment with each other (thereby creating a continuous guide section) and by moving the bending tool away from the one guide rail in the other guide rail. Intermediate steps involving the removal of a bending tool from a guide rail and reinsertion are not required due to the principle according to the invention.
    In order to realize a relative movement (displacement and / or rotation) between the tool store and the clipboard, it is possible to make the tool store and / or the clipboard movable. Due to the relative movement, the guide rail (s) of the clipboard can be aligned with different guide rails of the tool storage.
    By the measure according to the invention, on the one hand, the charging process can be accelerated and made more efficient, on the other hand, the potential storage density of bending tools in the tool storage increases.
    Preferably, the guide rails of the tool storage are formed on a common carrier.
    Preferably, when the feeder has at least one (upper tool) tool store and one intermediate store for upper tools movable relative to the upper tool store, and at least one (lower tool) tool store and an intermediate store for lower tools movable relative to the lower tool store. The upper tool and lower tool units of the charging device are preferably arranged one above the other (and according to the arrangement of the tool holders in a bending press).
    Also conceivable would be a three-dimensional tool storage in the manner of a shelving system, in which the clipboard would be relatively movable in two spatial directions to operate the individual guide rails of the tool storage.
    A preferred embodiment is characterized in that the clipboard comprises at least two guide rails for holding and guiding bending tools, wherein preferably a guide rail of the tool storage is in different relative positions of tool storage and clipboard in each case with another guide rail of the clipboard in alignment. This embodiment enables additional or extended maneuvering options: in particular, the shifting of a bending tool along a first guide rail of the clipboard into the guide rail (tool holder) of the bending press, while at the same time caching other bending tools in another (or second) guide rail of the clipboard.
    A preferred embodiment is characterized in that the guide rails of the tool storage and / or the clipboard parallel to zueinan or that the guide rails of the tool storage and / or the clipboard along a circular arc or a circular line are arranged extending in the radial direction. Such arrangements not only increase the storage density, but allow the realization of a relative movement between tool storage and clipboard by linear displacement and / or rotation.
    A preferred embodiment is characterized in that the clipboard is displaceable relative to the tool storage transversely to the longitudinal extension of its at least one guide rail. The required displacement paths can thereby be minimized. The clipboard here forms a kind of transfer table.
    In another embodiment, the clipboard may comprise a rotary unit through which the clipboard as a whole or a guide rail of the clipboard can be rotated, e.g. about an axis perpendicular to the longitudinal extent of the respective guide rail axis. As a result, the orientation or order of the bending tools can be reversed (for example when rotated through 180 °).
    One embodiment is that the guide rails of the tool storage and the guide rail (s) of the associated clipboard lie in one plane. However, it is alternatively possible for the guide rails to lie in different planes and e.g. form a "vertical" tool storage. In such a variant, the clipboard could approach the individual guide rails of the tool storage in the manner of a paternoster.
    A preferred embodiment is characterized in that the tool store is rotatable relative to the clipboard about an axis of rotation which is perpendicular to the plane defined by the at least two guide rails of the tool store. This allows a simple construction with a rotary drive.
    In another embodiment, the clipboard is movable relative to the tool storage along a circular or partially circular path. A circular contour of the tool storage can be optimally met.
    A preferred embodiment is characterized in that the loading device comprises at least one second transfer device for moving bending tools, wherein the second transfer device is associated with the clipboard and preferably integrated in the clipboard. A second transfer device expands the shunting options, particularly if it is designed to move bending tools from the clipboard back into the tool storage. Thus, bending tools can be moved with the first transfer device from the tool storage into the clipboard and with the second transfer device from the clipboard into the tool storage.
    The second transfer device may comprise a sliding element, which is movable by a drive along the guide rail (s) of the clipboard.
    In a preferred embodiment, the sliding element can be withdrawn from its drive position to a neutral position. In its neutral position, the sliding element can not interact with the guided in a guide rail of the clipboard bending tools. The retraction of the sliding element allows on the one hand the optional use of the second transport device and on the other hand, the method of the sliding element, without moving along a bending tool; the latter allows 'overhauling' of bending tools.
    In one possible embodiment, the second transfer device is arranged on the clipboard and can be moved with the clipboard. In an alternative embodiment, the second transfer device could be designed to be stationary relative to the clipboard; It could then be used for different guide rails, depending on which guide rail of the clipboard is in the effective range of the second transfer device.
    It is likewise preferred if the clipboard has at least two second transfer devices, wherein each of these (second) transfer devices is assigned to a different guide rail of the clipboard.
    A preferred embodiment is characterized in that the second transfer device is adapted to move bending tools from the clipboard into the (tool holder of) the bending press.
    A preferred embodiment is characterized in that the movement space of the second transfer device is limited to the area of the clipboard. As a result, collisions of the second transfer device during relative movement between the clipboard and tool storage are excluded from the outset. If the transfer device or its movement space extends to the end of a guide rail of the clipboard (for example, by a slider coming into contact with the bending tools), then nevertheless all the bending tools can be pushed out of the clipboard.
    A preferred embodiment is characterized in that the second transfer device has a storage drive, in particular a spring or cylinder storage drive, which is preferably acted upon by moving a bending tool from a guide rail of the tool storage in a guide rail of the clipboard. The actuation of the memory drive takes place via a control device, which is e.g. releases a lock which converts the stored energy into a movement of the transfer device.
    In an alternative embodiment, the second transfer device may have an active drive. Such a drive can be activated at any time and actuated by an external power supply. The active drive is in particular a (pneumatic) cylinder or a (servo-controlled) drive or motor. The active drive can be controlled by a control device.
    A preferred embodiment is characterized in that at least one guide rail of the tool storage at least two, preferably one
    Variety of bending tools arranged in a row. As already mentioned, the storage density can be increased by "arranging" bending tools in one row.
    A preferred embodiment is characterized in that the loading device comprises a control device, which is connected to the drive of the first transfer device and a drive for relative movement of tool storage and clipboard and is arranged to a loading operation, in which a bending press with at least one first bending tool is fed from the tool storage, wherein the at least one first bending tool is arranged together with at least one second bending tool in a first guide rail of the tool storage in a row and wherein the first bending tool from the at least one second bending tool by means of a maneuver by moving along Guide rails is disconnected. The advantages of a maneuvering maneuver and the maneuvering itself will be explained in detail below.
    A preferred embodiment is characterized in that the movement space of the first transfer device extends over at least one guide rail of the tool store and at least one guide rail of the clipboard.
    A preferred embodiment is characterized in that the first transfer device comprises a shuttle which can be moved along the guide rail and is preferably guided in the guide rail, in particular in the form of a carriage or carriage.
    A preferred embodiment is characterized in that the transfer device comprises an elongate, preferably flexible tensile and / or pressure transmission means, in particular a belt, a rope, a rod or a chain, and that the shuttle to the tension and / or pressure transmission means is connected. By using a tension and / or pressure transmission means, the travel drive of the transfer device can be arranged far away from the tool holders. The transfer device can thereby also be designed to be low in weight and space. The transmission means may be designed to transmit tensile forces or compressive forces or tensile and compressive forces. If the feeding or changing of the bending tools takes place only from one end of the rail, a tension and pressure transmission means is used.
    The transfer device, in particular the shuttle, preferably has a releasable coupling for connecting a bending tool. This allows the transfer device not only push the bending tools, but also pull. The clutch has a releasing (released) position and a coupling position and can be actuated by an actuator. The coupling may e.g. be designed as a mechanical clutch, magnetic clutch or as a suction device. The coupling can produce a frictional and / or positive connection with the bending tool. The actuator for actuating the clutch may comprise a cylinder-piston unit, a linear drive, a motor, a vacuum device and / or an electromagnetic device.
    In an alternative variant, the shuttle could also be designed to be self-propelled, wherein the travel drive is arranged in or on the shuttle. The transfer device can be constructed in this way particularly component-saving. The control of the shuttle could be wired, but also by radio.
    A preferred embodiment is characterized in that the bending tool is held in the guide rail by the same guide structure through which the transfer device (e.g., shuttle) passes. This is particularly advantageous since no separate guide structure has to be provided for the transfer device.
    The bending tool is formed, for example, by holding means projecting from the shank of the bending tool, such as e.g. Pins, pins or strips held. The holding means project into the guide structure of the guide rail, whereby the bending tool is held in the rail. The holding means may also be movable and e.g. be moved from a holding to a releasing position by an actuating element of the bending tool (so-called safety pins). This allows the insertion of the bending tools in a direction transverse to the longitudinal extent of the rail, but this is not required according to the present inventive principle when loading or changing.
    The guide structure in the guide rails can also be designed to hold the transfer device in the rail. The guiding structure formed within the rail has a function of folding in addition to the guiding function along the longitudinal extent of the rail by holding the transfer means in (or inside) the rail. The transfer device is slidable along the guide structure (i.e., parallel to the longitudinal extent of the rail) and held in the direction perpendicular to the longitudinal extent of the rail (i.e., in the direction from the rail interior to the rail opening) by the guide structure. The guide structure thus prevents the transfer device from falling out of the rail.
    Tool storage and clipboard are preferably mounted on a common frame or platform, with the tool storage and / or clipboard being movable relative to the frame (to get into different relative positions).
    A preferred embodiment is characterized by at least one further clipboard with at least one guide rail for holding and guiding bending tools. By means of the at least one further (or second) clipboard, the possibilities of maneuvering bending tools, in particular in connection with the extraction or regrouping of bending tools as well as the loading or changing process, can be expanded. The at least one additional clipboard can be arranged next to the tool storage or next to the (first) clipboard and receive from these - by moving along guide rails - bending tools.
    It should be mentioned at this point that all the properties described in connection with the (first) clipboard can also be transferred to the at least one additional clipboard.
    Two clipboards may also be juxtaposed and movable relative to each other (e.g., slidable).
    A preferred embodiment is characterized in that the tool storage and the at least one other clipboard are movable relative to each other and wherein at least one guide rail of the other clipboard is in alignment with different guide positions of tool storage and other clipboard in each case with another guide rail of the tool storage. The further (or second) clipboard can thus assume similar functions as the first clipboard. The overall functionality is significantly increased in particular by the possibility of temporarily storing bending tools on at least two clipboards.
    A preferred embodiment is characterized in that at least a portion of the tool storage is arranged between the clipboards. By this measure can be accessed from two sides on bending tools, which are housed in a guide rail of the tool storage in a row. Also, regrouping or separation processes are significantly facilitated. The clipboards may be stationary while the tool store is movable relative to the clipboards; or at least one clipboard may be movable; or there are tool storage and Zwischenablegen movable.
    A preferred embodiment is characterized in that in at least one relative position of tool storage and clipboards by a guide rail of a clipboard, a guide rail of the tool storage and a guide rail of another clipboard, a continuous guide portion is formed. In this way, a bending tool, which is accessed by a side (facing away from the bending press), can be conveyed through the continuous guide section into the bending press.
    A preferred embodiment is characterized in that the tool storage is annular and the clipboard is arranged in the area enclosed by the annular tool storage area. This represents a particularly space-saving solution.
    Preferably, the parking position of the first transfer device, in particular the parking position of the, preferably completely, retracted shuttle (for example slide), is located on a clipboard.
    A preferred embodiment is characterized in that a clipboard or a guide rail of the clipboard is rotatable. The bending tools or a number of bending tools can thereby be reoriented, which facilitates access to a specific bending tool and reduces the required shunting steps.
    A preferred possibility is that the clipboard is lowered or raised, in particular from the common plane with the tool storage. The rotation then takes place in the lowered or raised position. After the rotation, the clipboard is returned to the common plane with the tool storage. Of course, clipboard and / or tool storage can also be designed such that a rotation of the Zwischenablege is possible in the common plane.
    According to a preferred embodiment, a memory (upper tool) and a (lower tool) memory are distributed on at least two different horizontal planes. The tool store and the clipboard may additionally have relative vertical movement capability to align the clipboard with the corresponding tool store.
    It is preferred if the clipboard has at least two guide rails which run in two different horizontal planes.
    A preferred embodiment is characterized in that, in a first rotational position of the clipboard, one end of a guide rail of the clipboard is adjacent to the tool magazine and in a second rotational position of the clipboard the other end of the clipboard guide rail adjoins the tool magazine. In this way, the beginning of a series of bending tools (initially facing away from the tool store) can be turned towards the tool store by rotation, in particular by 180 °, and vice versa.
    A preferred embodiment is characterized in that the clipboard has a rotary unit through which the clipboard as a whole or a guide rail of the clipboard is rotatable, preferably about an axis perpendicular to the longitudinal extension of a guide rail of the clipboard. The turntable may e.g. comprise a rotary drive.
    In particular in connection with the latter embodiments, the maneuvering maneuver may also include - step (g) - rotating the clipboard about an axis of rotation (preferably 180 °).
    The object is also achieved with an arrangement of a bending press and a feeding device coupled thereto according to the present invention for feeding the bending press with bending tools, wherein the bending press has a tool holder formed as a guide rail for holding and guiding bending tools.
    A preferred embodiment is characterized in that the clipboard is arranged between the tool storage and the bending press. The total travel distance of all bending tools that are moved during a loading or changing operation can be minimized by this measure. Of course, an arrangement would be conceivable in which the tool storage between bending press and clipboard is arranged.
    A preferred embodiment is characterized in that the clipboard is movable relative to the tool holder of the bending press, preferably transversely to the longitudinal extent of its at least one guide rail is displaceable. This allows the bending press to be fed from various clipboard guide rails.
    A preferred embodiment is characterized in that in at least one relative position of the clipboard and the tool store, a continuous guide is formed from a guide rail of the tool store, a guide rail of the clipboard and the tool holder of the press brake designed as a guide rail. This allows the displacement of bending tools into the tool holder of the bending press by means of a first transfer device, which is preferably likewise guided in the guide rails.
    A preferred embodiment is therefore also characterized in that the movement space of the first transfer device extends over the guide rail of the tool storage, the guide rail of the clipboard and the tool holder of the bending press designed as a guide rail.
    A preferred embodiment is characterized in that the tool storage is arranged between the bending press and a clipboard. This clipboard is then facing away from the bending press, whereby their interaction with the tool storage can be done undisturbed (by the bending press). Also, no space is used in the bending press.
    The object of the invention is also achieved with a method for feeding a bending press with at least one first bending tool from a tool store of a loading device, wherein the tool store comprises at least two guide rails for holding and guiding bending tools and the bending press comprises at least one tool holder formed as a guide rail, characterized in that the at least one first bending tool is arranged together with at least one second bending tool in a first guide rail of the tool storage in a row and that the first bending tool is separated from the at least one second bending tool by means of a maneuvering maneuver by displacement (of bending tools) along guide rails.
    By "first bending tool" is meant a bending tool that is extracted from the row by the shunting operation to be shifted into the bending press. The term "second bending tool" is understood to mean a bending tool which remains in the loading device during the maneuvering maneuver or - if the maneuvering maneuver is carried out with the help of the tool holder of the bending press (designed as a guide rail) - is pushed back into the loading device before the bending operation with the first Bending tool is started. During the maneuvering maneuver, which may involve the displacement of the at least one first bending tool into a tool holder of the bending press formed as a guide rail, the bending tools involved in the maneuvering maneuver remain (uninterruptedly) inserted in guide rails. By "separating a first bending tool from the at least one second bending tool" is meant that the at least one first bending tool is extracted from the initial series of bending tools. The initial series of sequentially arranged bending tools is "torn" to gain access to the first bending tool.
    As already mentioned, bending tools remain uninterruptedly inserted in guide rails during the maneuvering maneuver. The transfer of a bending tool from a guide rail (eg the tool storage) into another guide rail (eg a clipboard or bending press) is accomplished by bringing the two guide rails into alignment with each other (thereby forming a continuous guide section) and by displacing the bending tool from the a guide rail in the other guide rail. With the method according to the invention it is possible to accommodate a plurality of bending tools in a guide rail of the tool storage in a row one behind the other, whereby the storage density of the tool storage is increased.
    A preferred embodiment is characterized in that the maneuvering maneuver with at least one movable along the guide rails Trans fereinrichtung takes place, wherein preferably the transfer device is guided in the guide rails.
    A preferred embodiment is characterized in that the maneuvering maneuver comprises the steps of: (a) displacing at least one bending tool from the first guide rail of the tool store onto a guide rail of a clipboard and (b) relative movement between tool store and clipboard. In order to extract or singulate a first bending tool from the initial series of bending tools, bending tools can be temporarily moved to the clipboard and stored there (between). Such maneuvers are carried out exclusively by shifting operations of bending tools along guide rails and Relativbewegien) between the clipboard and tool storage. In addition, the clipboard allows bending tools to be moved from one (or first) guide rail of the tool store to another (or second) guide rail of the tool store.
    Steps (a) and (b) are the basic principle of this embodiment and may be repeated many times. A preferred embodiment is characterized in that step (a) after step (b) is repeated at least once.
    The at least one step (a) preferably takes place with the first transfer device (already mentioned above).
    In one or more further steps, bending tools can be moved from the clipboard to the tool storage. This is preferably done by means of the second transfer device (already mentioned above).
    A preferred embodiment is characterized in that in step (a) the bending tools arranged in the first guide rail are displaced in the direction of the clipboard until the second bending tool (s) arranged in front of the at least one first bending tool in the guide rail of the Clipboard is / are, and that after step (b), the at least one first bending tool is moved in a step (c) of the first guide rail of the tool storage in a guide rail of the clipboard. The separation process is particularly easy here. In step (c), preferably only the at least one first bending tool is displaced into a guide rail of the clipboard, while any second bending tools which are arranged behind the first bending tool initially remain in the first guide rail of the tool storage (and become, for example, later in a Move step (d) to the clipboard).
    A preferred embodiment is characterized in that, between step (b) and step (c), the second bending tools interposed in the intermediate storage are displaced into at least one second guide rail of the tool storage. This variant is particularly suitable if the clipboard has only one guide rail, but in principle can also be applied to clipboards with multiple guide rails.
    A preferred embodiment is characterized in that in step (a) the second bending tool (s) are displaced into a first guide rail of the clipboard and in step (c) the at least one first bending tool is moved into a second guide rail of the clipboard is moved. This represents a preferred maneuvering maneuver, since with only a few steps, a separation of the first bending tool takes place.
    A preferred embodiment is characterized in that the maneuvering maneuver comprises the step of: (d) displacing the second bending tool (s) disposed behind the at least one first bending tool into the first guide rail of the clipboard, preferably before the at least one first bending tool is moved into the tool holder of the bending press. This process is particularly advantageous when the first transfer device pushes the bending tools from the tool store in the direction of the clipboard and subsequently in the direction of the bending press. In this embodiment, therefore, the rear second bending tools are separated and cached; The first bending tool is now isolated and can be moved with the first transfer device in the bending press.
    A preferred embodiment is characterized in that by step (b), the guide rail of the clipboard comes in alignment with another guide rail of the tool storage. So can be spent in a simple way and the intermediary of the clipboard bending tools from a guide rail of the tool storage in another guide rail.
    A preferred embodiment is characterized in that, by step (b), a second guide rail of the clipboard passes in alignment with the first guide rail of the tool storage. Thus, various tools of the initial series of bending tools (in the first guide rail of the tool storage) can be moved into different guide rails of the clipboard. The extraction or the Um series of bending tools can be done much faster.
    A preferred embodiment is characterized in that during the displacement of the at least one first bending tool in the tool holder of the bending press a continuous guide from a guide rail of the tool storage, a guide rail of the clipboard and formed as a guide rail tool holder of the bending press is formed.
    A preferred embodiment is characterized in that a plurality of bending tools by shunting in a predetermined order in a guide rail of a clipboard, which is movable relative to the tool storage, assembled before they are pushed into the tool holder of the bending press. This compilation can take place parallel to a bending process so that the selection or sorting of the tools has no influence on the cycle times.
    Another embodiment is characterized in that the (initially) arranged in a first guide rail of the tool storage in a row bending tools individually and or in groups are spent by a maneuvering maneuver on the clipboard in different guide rails of the tool storage, preferably each individual bending tool in a separate guide rail of the tool memory passes.
    A further embodiment is characterized in that the order of bending tools arranged in a guide rail is changed by a maneuvering maneuver.
    A preferred embodiment is characterized in that the maneuvering maneuver comprises the step of: (e) displacing at least one bending tool from a guide rail of the tool store or from a guide rail of the clipboard to a guide rail of another clipboard. The inclusion of another clipboard expands the maneuvering options, thereby reducing the number of intermediate steps required to extract and load bending tools.
    A preferred embodiment is characterized in that the maneuvering maneuver comprises the step of: (f) displacing at least one bending tool from a guide rail of a clipboard by a guide rail of the tool magazine onto a guide rail of another clipboard. This allows access to a bending tool also from a side facing away from the bending press. On the Werkzeugspiecher a guide rail is kept free for this purpose (at least temporarily) to perform such a transfer process can. For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    The charging device 10, in particular changing device, is used for loading a bending press 20 with bending tools 1 and / or for exchanging one or more bending tools used in a bending press 20.
    The charging device 10 comprises a tool storage 3 with at least two, preferably a plurality of guide rails 4, 5, 5 ', 5 ", 15 (see FIGS. 2 to 4) for holding and guiding bending tools 1, 2. First bending tools 1 designate bending tools which are to be released from the row of bending tools 1, 2 by a maneuvering maneuver, and are highlighted by a crossed hatching.
    The loading device 10 also comprises a clipboard 6 with at least one guide rail 7, 8 (see FIGS. 2, 11 and 20) for holding and guiding bending tools 1, 2. The tool storage 3 and the clipboard 6 are movable relative to each other. In the embodiment according to FIG. 1, tool store 3 and clipboard 6 are displaceable relative to one another in a direction perpendicular to the plane of the drawing. A (only schematically illustrated) drive 22 moves the tool storage 3 and a (also shown only schematically) drive 23 moves the clipboard 6. At this point it should be mentioned that it is not absolutely necessary that both tool storage 3 and clipboard 6 are movable. There are quite possible solutions in which only the tool storage or only the clipboard are movable (in particular displaceable or rotatable); see, e.g. Figures 2 and 23. The actuators 22 and / or 23 may e.g. be pneumatic drives. Also conceivable would be (line-ar-) motors, chain drives and the like.
    Here is at least one guide rail 7, 8 of the clipboard 6 in different relative positions of tool storage 3 and clipboard 6 each with a different guide rail 4, 5, 5 ', 5', 15 of the tool storage 3 in alignment.
    The loading device has at least one first transfer device 11 for displacing the bending tools 1, 2 along a guide rail 4, 5, 7, 8, 21. In the exemplary embodiment shown, the first transfer device 11 has a shuttle 19 (shown in FIG. 25) with a releasable coupling 24 for the temporary binding of a bending tool.
    The shuttle 19 can be moved along the guide rails, preferably guided in the guide rail (see FIG. 25). The shuttle 19 is connected to an elongated tension and / or pressure transmission means 18 which is driven by a drive 17. In an alternative variant, the shuttle 19 could be self-propelled.
    The movement space of the first transfer device 11 (here: the operating radius of the shuttle 19) extends over at least one guide rail 4, 5 of the tool store 3 and at least one guide rail 7, 8 of the clipboard 6.
    FIGS. 2 and 3 show an exemplary embodiment of a charging device 10. The guide rails 4, 5, 5 ', 5 ", 5" of the tool storage 3 are arranged running along a circular arc or a circular line in the radial direction. The tool storage 3 is rotatable about a (perpendicular to the plane or perpendicular to the plane defined by the guide rails of the tool storage plane) axis of rotation.
    The guide rails 4, 5, 5 ', 5 "of the tool storage 3 each hold a plurality of bending tools 1,2 arranged in a row (FIG. 2). The first bending tools 1 are those with which the bending press 20 is to be charged.
    They must therefore be separated from the second bending tools 2 (FIG. 3). This is done according to the invention by means of a maneuvering maneuver by moving bending tools along guide rails. In the following figures, the first bending tools 1 are each characterized by a crossed hatching and the second bending tools 2 by a simple hatching for ease of distinctness.
    The terms "first guide rail", "second guide rail" and "storage guide rail" used below are intended to facilitate the understanding of the invention. In particular, it should be illustrated that different guide rails can be involved in a maneuvering maneuver and that bending tools are moved from one guide rail to another guide rail. It is quite possible and preferred if all guide rails are of similar design.
    4 to 10 show in individual steps as bending tools, which are arranged in a guide rail in a row one behind the other, are separated from each other. 4 shows the starting position in which bending tools 1, 2 are mounted in a first guide rail 4. The first guide rail 4 is aligned with the guide rail 7 of the clipboard. The guide rails 15 are (still) empty and serve subsequently as "siding". First, the entire row is displaced by means of first transfer device 11 into the guide rail 7 of the clipboard (FIG. 5). After the transfer device is returned to its original position (as in FIG. 4), the tool store is rotated (clockwise), so that now one of the store guide rails 15 is aligned with the guide rail 7 (FIG. 6). The first transfer device 11 moves into said Abstell-guide rail 15 to couple to the rearmost of the stored in the clipboard 6 bending tools and this in the Abstell-guide rail 15 to pull (Fig. 7).
    Subsequently, the transfer device 11 is moved back to its original position and the tool storage 3 we again rotated (clockwise) to a guide rail, so now another Abstell-guide rail 15 with the guide rail 7 of the clipboard 6 is in curse- tender alignment (Fig. 8) Again, the rearmost bending tool is pulled into the relevant parking guide rail (Fig. 9).
    These steps are repeated until all the bending tools are separated and each housed in another Abstell-guide rail 15. The Rangierma-növer of FIG. 4 to 10 represents a way to separate bending tools from each other or reassemble in a different order. The latter can be achieved by reversing the individual steps in a different order. Furthermore, a maneuver can be performed parallel to a bending process, so that the selection and sorting of the bending tools has no influence on the cycle times.
    11 shows a variant of the charging device 10 according to the invention: The intermediate deposit 6 here comprises two guide rails 7, 8 for holding and guiding bending tools 1, 2. Here is a (first) guide rail 4 of the tool storage 3 in different relative positions of tool storage 3 and clipboard 6 each with a different guide rail 7, 8 of the clipboard 6 in alignment. The two guide rails 7, 8 parallel to each other and are formed on a common carrier. In this embodiment, the clipboard 6 is displaceable transversely to the longitudinal extension of its guide rails 7, 8 (by means of a drive 23, Fig. 1). The first guide rail 7 may e.g. as 'working rail' (for pushing through bending tools in the bending press) and the second guide rail 8 as 'parking rail' (for temporary storage) can be used.
    In the case of an annular tool storage, as shown in Fig. 11, the two guide rails 7, 8 - may alternatively extend along two radial directions which pass through the axis of rotation of the tool storage 3. The clipboard 6 could then be movable concentrically with the tool storage 3 along a circular or partially circular path. The sequence of shunting maneuvers could be the same as described below.
    A possible maneuvering maneuver with such a clipboard 6 will now be described with reference to FIGS. 11 to 18. FIG. 11 shows the starting position in which a first bending tool 1 and a plurality of second bending tools 2 are arranged in a row in a first guide rail 4 of the tool store 3 are. The first guide rail 4 of the tool storage 3 is in alignment with the first guide rail 7 of the clipboard 6.
    The first transfer device 11 now shifts in a step (a) arranged in the first guide rail 4 of the tool storage 3 bending tools 1, 2 in the direction of clipboard 6 until the front of at least one first bending tool 1 arranged second bending tools 2 in the first guide rail 7 of the clipboard 6 are (Figure 12). The first bending tool still remains in the tool storage 3.
    Now, in a step (b), a relative movement takes place between the tool store 3 and the clipboard 6, so that the second guide rail 8 of the clipboard 6 comes into alignment with the first guide rail 4 of the tool store 3 (FIG. 13). Thereafter, in a step (c), the first bending tool 1 is displaced from the first guide rail 4 of the tool storage 3 into the second guide rail 8 of the clipboard 6 (FIG. 14). The second bending tools 2 arranged behind the first bending tool 1 remain in the first guide rail 4 of the tool storage 3 for the time being.
    Subsequently, a step (b) takes place again: relative movement between the tool store 3 and the clipboard 6, the first guide rail 7 of the clipboard 8 now again being in alignment with the first guide rail 4 of the tool store 3 (FIG. 15).
    The maneuvering maneuver now comprises the step: (d) shifting the second bending tools 2, which were (initially) arranged behind the first bending tool 1, into the first guide rail 7 of the clipboard 6 (FIG. 16). There they are united with the initially arranged in front of the first bending tool 1 second bending tools 2. This step takes place here before the first bending tool 1 is moved into the guide rail 21 (tool holder) of the bending press 20.
    Subsequently, a step (b) is again carried out: relative movement in order to bring the second guide rail 7 of the clipboard 6 into alignment with the first guide rail 4 of the tool store 3 (FIG. 17). Subsequently, the first bending tool 1 extracted in this way is shifted with the first transfer device 11 into the bending press 20 (FIG. 18). During the entire maneuvering maneuver, the bending tools involved in the maneuvering maneuver remain uninterruptedly inserted in guide rails. Although the bending tools change the guide rails, they do not have to be taken out and reused elsewhere. The transition takes place exclusively by moving along guide rails.
    FIG. 19 shows a preferred embodiment in which the loading device 10 comprises at least one second transfer device 12 for moving bending tools 1, 2. This is assigned in the illustrated embodiment, the clipboard 6 and preferably integrated in the clipboard 6. The range of movement of the second transfer device 12 is here limited to the area of the clipboard 6 (i.e., the second transfer device 12 does not extend beyond the end of the guide rails 7, 8).
    The second transfer device 12 can have a (sliding) drive 13, in particular a storage drive (for example a spring or cylinder storage drive). The (storage) drive 13 can be acted upon by moving a bending tool 1, 2 of a guide rail 4, 5 of the tool storage 3 in a guide rail 7, 8 of the clipboard 6. In this case, it is "loaded" by the first transfer device 11. A sliding member 14 (e.g., a finger) operatively connected to the drive 13 cooperates with the bending tools. In the illustrated embodiment, the second transfer device 12 acts only in the direction of the tool storage 3 (so it can move the bending tools only in the tool memory back). Of course, a second transfer device acting in both directions is also conceivable (for example a double-acting cylinder, a servo drive or, generally, an active drive). Incidentally, the clipboard 7 shown in FIGS. 2 to 10 could also be equipped with a second transfer device.
    FIGS. 20 to 21 show a variant of a charging device 10 which differs from the preceding variants in two respects: the tool storage 3 comprises guide rails running parallel to one another; and the clipboard includes several (here: six) guide rails. Both tool storage 3 and clipboard 6 are each independently (and in each case relative to the guide rail 21 of the bending press 20) displaceable.
    In the following, a further maneuvering maneuver for separating bending tools is described with reference to FIGS. 20 to 21. In a starting position, all the bending tools are in the tool store 3. The individual bending tools, which initially sit in the same guide rail of the tool store 3, are successively placed on the guide rails of the clipboard 6 divided (Fig. 21 and 22). Between the individual shift steps, the clipboard 6 is moved in each case by a guide rail relative to the tool storage 3.
    Finally, FIG. 23 shows a further variant in which the clipboard 6 comprises only one guide rail 7. However, this is a second transfer device 12 of the type mentioned above, equipped with an active, double-acting drive 13 assigned. With this second transfer device 12 bending tools (similar to the maneuver described with reference to FIGS. 4 to 10) can be distributed to the initially empty Abstell guide rails 15 of the buffer. For this process, the first transfer device 11 is not essential.
    FIG. 1 shows that the loading device 10 comprises a control device 16, which is connected to the drive 17 of the first transfer device 11 and to the drives 22 and 23 for moving (relative) the tool storage 3 and the clipboard 6. The control device 16 controls a charging process in which a bending press 20 is loaded with at least one first bending tool 1 from the tool storage 3. In this case, (initially) the at least one first bending tool 1 is arranged together with at least one second bending tool 2 in a (first) guide rail 4 of the tool storage 3 in a row. The first bending tool 1 is separated from the at least one second bending tool 2 by means of a maneuvering maneuver by displacement along guide rails 4, 5, 7, 8, 21.
    In the illustrated embodiments, the clipboard 6 is disposed between the tool storage 3 and the bending press 20.
    It is also preferred if, according to the embodiments of FIGS. 11 to 22, the clipboard 6 is movable relative to the tool holder of the bending press 20, preferably transversely to the longitudinal extension of its at least one guide rail 7, 8 is displaceable. This results in different relative positions different guide rails 7, 8 of the clipboard in alignment with the guide rail 21 of the tool holder 25th
    It can also be seen from the figures that in at least one relative position of the clipboard 6 and tool store 3, a continuous guide consists of a guide rail 4, 5 of the tool store 3, a guide rail 7, 8 of the clipboard 6 and the tool holder of the bending press 20 designed as a guide rail 21 is formed. The movement space of the first transfer device 11 extends over the guide rail 4, 5 of the tool storage 3, the guide rail 7, 8 of the clipboard 6 and formed as a guide rail 21 tool holder of the bending press 20th
    Fig. 24 and Fig. 27 show a possible embodiment of a loading device with a circular upper tool storage 3 and associated clipboard 6 for upper tools and with a lower tool storage. Upper tool and lower tool units of the feeder are arranged one above the other according to the arrangement of the tool holders in a bending press. Tool storage and clipboards are mounted on a common frame 26. In the illustrated embodiment, the tool stores are rotatable and thus movable relative to the clipboard.
    FIGS. 24 and 27 show an embodiment in which the loading device has two intermediate trays 6, 6 'each having at least one guide rail 7, 7' for holding and guiding bending tools 1, 2.
    In this case, the tool storage 3 relative to the clipboards 6, 6 'movable, wherein (as already described in connection with the first clipboard 6) and at least one guide rail 7' of the other clipboard 6 'in different relative positions of tool storage 3 and further clipboard 6' each with a different guide rail 4, 5 of the tool storage 3 is in alignment.
    It can be seen that at least a portion of the tool storage 3 is disposed between the clipboards 6, 6 '. It can be formed in at least one relative position of tool storage 3 and clipboards 6, 6 'by a guide rail 7 a clipboard 6, a guide rail 4 of the tool storage 3 and a guide rail 7' another clipboard 6 'a continuous guide portion.
    In Figs. 24 and 27, the tool storage 3 is annular and a clipboard 6 is disposed in the area enclosed by the annular tool storage 3.
    FIGS. 28 and 29 show an embodiment with a (linearly) displaceable tool store 3, which has guide rails 4, 5 running parallel to one another. Left and right next to the tool storage 3 clipboards 6, 6 'can be arranged.
    Fig. 30 shows a particularly preferred embodiment in which the clipboard 6 is rotatable about a rotation axis 27 (indicated by an arrow). Alternatively, only the guide rail 7 of the clipboard 6 could be rotatable. In a first rotational position of the clipboard 6, one end of the guide rail 7 of the clipboard 6 adjoins the tool magazine 3 and in a second (rotated by 180 °) rotational position of the clipboard 6 the other end of the guide rail 7 of the clipboard 6 adjoins the tool magazine 3. Of course, the rotatable clipboard 6 may also have more than just a guide rail.
    The clipboard 6 can be lowered or raised from the common plane with the tool storage 3. The rotation then takes place in the lowered or raised position. After rotation, the clipboard 6 is again brought into the common plane with the tool storage 3.
    The clipboard 6 has a rotary unit 28 (or cooperates with such), through which the clipboard 6 as a whole or a guide rail 7 of the clipboard 6 is rotatable, preferably about an axis perpendicular to the longitudinal extent of the guide rail 7 of the clipboard 6 axis.
    It can be seen from FIGS. 24, 27, 28 and 29 that the tool storage 3 can be arranged between the bending press 20 and a clipboard 6. It can also be seen that the parking position of the first transfer device 11, in particular the parking position of the preferably completely retracted shuttle 19 (for example a slider), is located on a clipboard 6.
    In particular, in connection with a tool storage of parallel guide rails is also preferred that the tool storage is stationary and the clipboard (relative to the frame) movable.
    In the following, preferred embodiments of a method for feeding a bending press 20 with at least one first bending tool 1 from a tool storage 3 of a charging device 10 will be described.
    In the starting position, at least one first bending tool 1 is arranged together with at least one second bending tool 2 in a first guide rail 4 of the tool storage 3 in a row. The first bending tool 1 is separated from the at least one second bending tool 2 by means of a maneuvering maneuver by displacement along guide rails 4, 5, 5 ', 5 ", 15, 7, 8, 21. The bending tools involved remain uninterruptedly inserted in guide rails.
    The maneuvering is done with at least one movable along the guide rails transfer device 11, 12, which is preferably guided in the guide rails.
    As already mentioned with reference to the figures, the shunting maneuver comprises the steps: (a) shifting at least one bending tool 1, 2 from the first guide rail 4 of the tool store 3 to a guide rail 7, 8 of a clipboard 6 and (b) relative movement between tool store 3 and clipboard 6 ,
    These steps can be repeated as often as required. That Step (a) may be repeated at least once after step (b) and / or step (b) may be repeated at least once after step (a).
    By step (b) passes the guide rail 7, 8 of the clipboard 6 in alignment with another guide rail 4, 5 of the tool storage 3. It is also preferred if by step (b) a second guide rail 8 of the clipboard 6 in alignment with the first guide rail 4 of the tool storage 3 passes.
    The maneuvering maneuver can be carried out in such a way that in step (a) the bending tools 1, 2 arranged in the first guide rail 4 of the tool store 3 are displaced in the direction of the clipboard 6 until the second (s) arranged at least one first bending tool 1 Bending tool (s) 2 in the guide rail 7 of the clipboard 6 is / are. Subsequently, step (b) is carried out: relative movement between tool storage 3 and clipboard 6.
    Then, the at least one first bending tool 1 is moved in a step (c) of the first guide rail 4 of the tool storage 3 in a guide rail 8 of the clipboard 6. The second bending tools 2 are preferably displaced into a different guide rail of the buffer 6 than the at least one first bending tool 1.
    Preferably, between the step (b) and the step (c), the second bending tool (s) 2 temporarily stored in the clipboard 6 is displaced into at least one second guide rail 5 of the tool magazine 3. Such a maneuvering maneuver can thus be carried out with a clipboard, which has only one guide rail.
    If the clipboard has at least two guide rails, as shown in FIGS. 11 to 22, the following shunting maneuver is preferred: In step (a), the second bending tool (s) 2 is / are inserted into a first guide rail 7 Shifted clipboard 6 and moved in step (c) the at least one first bending tool 1 in a second guide rail 8 of the clipboard 6.
    In a further variant, a plurality of bending tools are assembled by shunting operations in a predetermined sequence in a guide rail 7, 8 of a clipboard 6, which is movable relative to the tool storage 3, before they are pushed into the tool holder 25 of the bending press 20.
    A further embodiment is characterized in that the (initially) in a first guide rail of the tool storage in a row arranged bending tools individually and or in groups are spent by a maneuvering maneuver via the clipboard in different (storage) guide rails 15 of the tool storage 3. Preferably, each individual bending tool passes into a separate guide rail 15 of the tool storage 3 (see FIGS. 4 to 10).
    A further embodiment is characterized in that the order of bending tools arranged in a guide rail is changed by a maneuvering maneuver.
    Preferred embodiments also take into account the use of another clipboard 6 '. The maneuvering maneuver may comprise a step (e) here: displacement of at least one bending tool 1, 2 from a guide rail 4 of the tool store 3 or from a guide rail 7 of the clipboard 6 to a guide rail 7 'of a further clipboard 6'.
    A possible step (f) results from the variants shown in FIGS. 24, 27, 28 and 29: displacement of at least one bending tool 1, 2 from a guide rail 7 of a clipboard 6 through a guide rail 4 of the tool storage 3 onto a guide rail 7 ' another clipboard 6 '.
    In connection with FIG. 30, the shunting maneuver may also include rotating the clipboard 6 about the axis of rotation 27 (preferably by 180 °).
    As already mentioned, all the properties and method steps that have been described in connection with the (first) clipboard 6 can be transferred to the at least one further (or second) clipboard 6 'or implemented in this case.
    In addition, it is possible to combine the described features and method steps to obtain special operational sequences. Taking into account the variant of FIG. 27, for example, with a shuttle 19, it is possible to move a tool 1 from the guide rail 21 of the bending press to the guide rail 7 via the guide rail 7 'of the clipboard 6' and the guide rail 4 of the tool store 3. Subsequently, after the relative movement between the clipboard 6 and the tool storage 3, it is possible to move a tool from the guide rail 5 to the guide rail 7 'or the guide rail 21 while passing the guide rail 4 and using an opposite sequence.
