    The invention relates to a production plant with a bending press, as specified in claim 1.
    Several different devices are known from the prior art, which enabled the automatic setup of bending tools on a bending press. In most cases, a manipulation robot or the backgauge unit is used to equip the bending tools on the bending machine. In this case, the bending tool is removed from the tool store by means of the manipulation robot or the back stop unit and positioned in the tool holder depending on the tool receiving system. One possibility here is that the bending tool is inserted along the longitudinal direction of the tool holder indiese and thus positioned. Another possibility consists in the fact that the bending tool is used by the manipulation robot or the back stop unit directly at its end position in a direction perpendicular to the longitudinal direction, wherein in the bending tools a latching mechanism for inserting the tool must be present.
    These embodiments have the disadvantage that the manipulation robot or the back stop unit must have a large working range in order to be able to position the bending tools along the entire longitudinal extent of the tool holder. As a result, the manipulation robot or the backstop unit become very complex and very difficult. Furthermore, the bending tools can only be removed individually from the tool magazine and inserted into the tool holder, which involves a high expenditure of time.
    Furthermore, devices are known in which a bending tool is inserted from a Mani¬pulationsvorrichtung in the tool storage and is then positioned by means of a spindle drive or by means of a rack in the longitudinal direction of the tool memory.
    These embodiments have the disadvantage that a spindle drive, a rack or a rack are expensive to produce and are therefore expensive to purchase. Furthermore, separate receiving constructions for receiving the bending tools have to be used for such a drive method, whereby the complexity of the production system increases again.
    It is an object of the present invention to provide a manufacturing facility for bending sheet metal workpieces which has an improved tooling apparatus.
    This object of the invention is achieved by the measures according to claim 1.
    According to the invention, a production plant, in particular for the free bending of workpieces to be produced from sheet metal, is formed. The production plant comprises a bending press, in particular a press brake, with a machine frame and press beam and slit-like tool receivers arranged on the press beams, bending tools in the form of a bending die or a bending die, a tool store for at least one bending tool, a first manipulation device for transferring the Biegewerkεzeuges between the tool storage and the tool holders, anda second manipulation device for positioning the bending tool in a longitudinal alignment of the tool holder, the second Manipulations¬ device comprises a guided over at least two deflection means traction means, on which pulling means at least one driver element is arranged. The bending tool has, in a direction parallel to a bending edge, at least one slot extending over the length of the bending tool for the passage of the at least one traction means, wherein the at least one slot is further dimensioned such that the at least one driving element can not be passed through the slot is.
    An advantage of the design according to the invention is that such a designed, second manipulation device for positioning the Biegewerkzeu¬ge, may consist of a few, simply constructed items. As a result, not only can the manipulation device be as robust as possible and nevertheless lightweight, but it can also be produced inexpensively. Furthermore, such a built manipulation device is not very maintenance intensive. In addition, due to the simple structure, an excessive susceptibility to error of the manipulation device can be obstructed. Advantageously, the expression according to which the traction means is guided in a slot of the bending tool, since thus the traction means can be protected from environmental influences, whereby a damage of the traction means can be obstructed. Furthermore, the combination of a manipulation device for inserting the bending tools with a manipulating device for positioning the bending tools is very advantageous since this can greatly reduce set-up times.
    Furthermore, it can be provided that the at least one traction means is formed as a rope. It is advantageous in this case that a traction means, which e.g. is designed in the form of a steel cable, is particularly robust and resistant. Furthermore, trained in the form of a rope traction means is very low wear and can beirelativ record small amounts of high forces. Another advantage is that a rope can be easily deflected, and a deflection roller need not have a complicated geometry.
    Furthermore, it may be expedient if the at least one driver element surrounds the traction means and has an essentially rotationally symmetrical basic shape. It is advantageous here that a driver element with essentially rotationally symmetrical basic shape does not have to be attached to the traction means in a specific angular position. Furthermore, in the case of a driver element with rotation-symmetrical basic shape, a rotation of the traction means during operation does not have a negative influence on the functionality of the manipulation device. This is particularly advantageous when using a rope as Zug¬ medium, since a rope against rotation about its longitudinal axis is not very stable. This is particularly true for an endless and guided around two deflection means of the case. Such a driver element, which surrounds the traction means, on the one hand can be arranged centrally on the traction means. Furthermore, such a member element can be equipped with a simple fastening system, so that it can be easily attached to the traction means.
    Furthermore, it can be provided that the working area of the at least one pulling means extends substantially over the entire length of the tool holder. The advantage here is that thus the bending tools can be positioned on the Gesamtlän¬ge the tool holder. In this case, it is quite possible that the working area on the side of the machine to which the tool storage is connected is somewhat shortened.
    Furthermore, it may be expedient if the second manipulation device is positioned such that at least one section of the at least one traction means is arranged inside the clear cross section of the slot-like tool holder so that it can be brought into engagement with the bending tool Pulling means is well protected against environmental influences. Furthermore, it can be achieved that the space requirement of the second manipulation device can be kept low. This results from the fact that the essential components of the second manipulation device can be arranged within the tool holder. Thus, the number of protruding from the tool holder parts is minimized.
    Furthermore, it may be advantageous for the bending tools to be equipped with a first pulling means, by means of which the bending tools can be positioned in a first direction of the longitudinal direction of the tool holder, and a second pulling means is provided, by which the bending tools are in a second direction opposite to the first direction Hereby, the individual bending tools can be easily and quickly positioned. This is achieved in that a respective engaging element attached to a traction means can be positioned on one side of the bending press, in particular the tool holder. Thus, the bending tools can be selectively shifted in the first direction or in the second direction without having to move a driver element to the second side of the bending tools. Furthermore, it can be achieved that the bending tools can be brought together, for example, in order to be able to reduce gaps between the individual bending tools.
    In a special embodiment, it can be provided that the second manipulation device comprises at least two cable drums connected to a drive unit, between which the at least one cable-shaped traction means is tensioned, and to which cable drums the at least one cable-shaped traction means can be wound alternately. The advantage here is that no endless traction means is required by the use of two driven cable drums on which the rope-shaped traction means is wound up alternately. Thus, the space required can be kept as low as possible. Furthermore, thus no Spannvorrich¬ tion is necessary in which an endless circulating rope must be stretched.
    Alternatively, it can be provided that the second manipulation device comprises at least one drive unit which is bewe¬ gungsgekoppelt with a deflection, by means of which drive unit, the traction means is movable and positionable, wherein the traction means is ausgebil¬det circulating Endloszugmittel. In this case, it is advantageous that, in contrast to the design with alternate winding of the traction means on two cable drums, only one driven cam unit is required. Thus, such a manipulation device constructed in such a way can be made considerably less expensive than a manipulation device with two driven deflecting means.
    In a further development it can be provided that the deflection unit is designed as Umlenk¬ role. The design of the deflection unit as a deflection roller brings with it the advantage that a deflection roller can be manufactured easily. This makes them less prone to errors and inexpensive to manufacture. Furthermore, a spool is very low wear, which also maintenance costs can be kept low.
    Furthermore, it may be expedient that at least one deflection means is displaceable transversely to the longitudinal alignment of the tool holder, whereby the driver element attached to a subsection of the traction means can be brought into engagement with the bending tool. It is advantageous here that can be achieved by this measure that the Mitneh¬merelement mounted on the traction means, which is normally in engagement with the bending tool in that the bending tool can be moved by the traction means, can be moved in the vertical direction in that it is no longer in operative engagement with the bending tool. Thereby, the driver element can be positi¬oniert on the opposite side of the bending tool or the bending tools, whereby the bending tools can be moved with only one driver element optionally in the first direction or in the second direction along the Längsaus¬richtung the tool holder.
    According to a further development, provision can be made for a guide element which is displaceable transversely to the longitudinal alignment of the tool receptacle and to act on the subsection to be formed between the deflecting means, whereby the entrainment element fastened to the subsection of the traction means can be brought into engagement with the bending tool. It is advantageous here that the deflecting means do not have to be displaced transversely to the longitudinal alignment of the tool holder due to a der¬artige measure, since the traction means or the Mitneh¬merelement can be brought by the guide member with a bending tool in operative engagement.
    Furthermore, it may be advantageous that at least one deflecting means is looped around several times by the traction means. This may be necessary in that deflection, which serves as a drive for the traction means. Especially when high forces are to be absorbed on a traction device, which is designed as a cable, multiple wrapping can be advantageous in order to be able to apply sufficient frictional force.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component designations, wherein the disclosures contained in the entire description apply mutatis mutandis to the same parts with the same reference numerals. same component names can be transferred. Also, the location information chosen in the description, such as up, down, laterally, etc. related to the directly described and illustrated figure and these conditions are to be transferred in a change in position mutatis mutandis to the new situation.
    FIGS. 1 to 12 show a production plant 1 for free bending of workpieces 2 to be manufactured from sheet metal, as well as variants thereof in a schematically simplified representation.
    The production line 1 comprises a bending press 3, in particular a press brake, for producing the workpieces 2 or workpieces between relatively adjustable bending tools 4, such as bending punch 5 and bending die 6. The bending punch 5 can also act as an upper tool and the bending die 6 also be referred to as a lower tool.
    A machine frame 7 of the bending press 3 comprises, for example, a bottom plate 8, on which vertically upwardly spaced, spaced apart in the transverse direction and can be arranged parallel to each other aligned side cheeks 9,10. Die¬se are preferably connected by a solid, for example, formed from a sheet metal part cross member 11 at their distance from the bottom plate 8 Endbe¬reichen each other.
    The side cheeks 9, 10 may be formed approximately C-shaped to form a free space for forming the workpiece 2, wherein a fixed, insbeson¬dere on the bottom plate 8 upstanding, press bar 13 may be attached to front end faces 12von bottom legs of the side cheeks , Die¬ser press bar 13 may also be referred to as a table bar. An of the
    Bottom plate 8 remote legs of front end faces 14 may be in Gela ledges 15 in a Linearfüh¬ ments 15 to the table beam forming the pressing beam 13 a relatively adjustable further pressing bar 16, in particular a pressure bar. On opposite, parallel to each other extending end faces 17,18 of the two pressing bars 13,16 Werkzeugaufnahmen19, 20 arranged for assembly with the bending tools 4 and be trained.
    The bending press 3 shown has, as drive arrangement 21 for the adjustable pressure bar 16, namely the pressure bar, at least one, here two drive means 22, which are e.g. are fed with electrical energy from a power grid 23 and additionally can be line connected to a control device 24. By way of example, the operation of the bending press 3 is controlled via a line-connected input terminal 25 connected to the control device 24.
    The drive means 22 may be e.g. to act electromotive spindle drives 26, as they are well known, of which adjusting means 27 for a re¬versible adjusting movement of the pressure bar formed by the upper Pressbalken 16 with this, for example, drive connected. Irrespective of this, it would also be possible to form the drive means 22 by means of hydraulically and / or pneumatically actuatable actuating means. It can find cylinder-piston arrangements application. However, other drive means, such as e.g. Eccentric drives, toggle lever drives, rack drives, etc. conceivable. All the above-mentioned execution features or individual features of the Figu¬renbeschreibung are called to describe an exemplary manufacturing plant 1 or bending press 3, which can be made in the essential to the invention, the following parts of the figure description. All described individual features are therefore not necessarily required for the embodiment according to the invention and can be omitted or replaced by other features in order to obtain a functioning bending press 3.
    Further details required for the operation of such a bending press 3, such as safety devices, stop arrangements, control and measuring devices, are omitted in the present description for the avoidance of an unnecessary length of the description.
    Furthermore, the manufacturing plant 1 may also include a manipulator not shown here in detail, which of a supply stack of deformable or. abzukantenden sheets takes at least a piece of it and spends in the working area or the operating side of the bending press 3.
    Furthermore, it is shown here in simplified form that the bending tools 4, in particular the bending punch 5 and / or the bending die 6, can have their own recesses 28, 29 for manipulating the same. Manipulation of the bending tool 4 is understood here to mean that this or its bending die 5 and / or bending die 6 are automatically removed by means of a first manipulation device 30 from a tool store 31 shown in simplified form in FIG an insertion position 32 of Werkzeugzeugaufnahmen 19, 20 of the pressing bars 13,16 spent and used there and clamped as is held. In this case, it is also possible to speak of a tool change system with which the exchange operations can be carried out with the plant components required for this purpose.
    This first manipulation device 30 can be executed in the form of a manipulator, which is used, for example, for workpiece handling. Furthermore, it is possible for the manipulation device 30 to be formed, for example, by a backstop unit which is designed to also handle manipulation activities. In addition to these and other possible Ausfüh¬rungsvarianten it is also possible that as manipulation device 30 ei¬gens for the purpose of handling of bending tools trained Manipula¬tor is used.
    The embodiment of a device for setting up bending tools described in FIGS. 2 to 12 is explained and illustrated for use at a lower tool receptacle 19. Analogous to the description made here, an upper tool holder 20 can also be equipped with bending tools 4 in the same way. For the sake of brevity, however, an exact description, resp. dispensed with a graphic representation of such a tool holder 20 Upper.
    FIG. 2 shows a schematic representation of the front view of a bending press 3, in particular of the first press beam 13 and the first tool holder 19. It can be clearly seen that besides a first manipulation device 30 in the production line 1, a second manipulation device 33 is also arranged is adapted to spend the bending tools 4 of the Einsetzpo¬sition 32 in its final position along the longitudinal alignment 34 in the tool holder 19 receiving.
    For this purpose, the manipulation device 33 comprises at least one traction means 37, guided over two deflecting means 35, 36, on which at least one entrainment element 38 is arranged.
    For a better understanding of the structure of such a manipulation device 33, FIGS. 3 to 5 show various possible embodiments for traction means 37 and for entrainment elements 38.
    As shown in Fig. 3, the traction means 37, for example, be executed as a cable 39. Such a cable 39 can be made in the form of a common steel rope or plastic rope. The diameter 40 of the cable 39 depends on the tensile force to be applied and is preferably between 1 mm and 5 mm.
    Furthermore, it is also possible that the traction means 37, as shown for example in FIG. 4, is designed as a toothed belt or as a V-belt or flat belt.
    In yet another variant, it is possible that the traction means 37, as shown in Figure 5, is designed as a chain.
    However, the various design possibilities of such a traction means 37 are not limited to the examples that have been carried out. It is also conceivable that further, not shown, traction means forms are used as traction means 37 in the manipulation device 33.
    Like the traction means 37, the entrainment element 38 can also be designed in a wide variety of embodiments, with the embodiments illustrated in FIGS. 3 to 5 showing a small section of the possible design possibilities.
    The driver element 38 shown by way of example in FIG. 3 can be designed, for example, as a cylindrical element which is fastened to the traction means 37. This driver element 38 designed as a cylindrical element has a larger diameter 41 than the rope diameter 40. Several different types of fastening may be provided for fastening the driver element 38 to the traction means 37. For example, it is conceivable that the driver element 38 has a dividing plane 42 extending through the central axis of the cylindrical element, through which the driver element 38 is divided into two halves. As a result, the driver element 38 can be easily attached to the traction means 37 and fastened by means of fastening means 43. Furthermore, it is also conceivable that the two halves of the driver element 38 formed by the separating plane 42 are fastened to one another or fastened to the traction means 37, for example, by a material connection such as an adhesive bond, solder joint or welded connection.
    As shown in Fig. 4, the driver element 38 may also be formed as a flat product, which may be fastened by means of a fastening means 43 on the traction means 37, such as a toothed belt. It can be provided that the driver element 38 is either screwed directly to the traction means 37, or that, for example, a counter-holder element is carried out, by means of which the driver element 38 is screwed and thus the traction means 37 is clamped.
    As shown in Fig. 5, it is also possible that the driver element 38 is diεrectly attached to the traction means 37 and is approximately executed as a simple projecting tab. Furthermore, it is also conceivable that the driver element 38 spielsweise formed as a chain link and thus part of the dargestell¬ten in Fig. 5 chain. The embodiments or attachment shapes of the Mitneh¬merelementes 38 on the traction means 37 are not by the embodiments inFig. 3 to 5, but rather it is conceivable that also other types of driver elements 38 or of fastening means 43 are used.
    The embodiments just described of different tension means 37 or entrainment elements 38 can be used in the manipulation device 33 shown in FIG.
    After this insertion for the possible embodiment of different tension means 37 or driver elements 38, the possibilities for the configuration of the manipulation device 33 will be further described with reference to FIG.
    One embodiment is that, as shown in Fig. 2, the pulling means 37 is guided over two deflection means 35, 36, wherein the deflection means 35, 36 are formed as guide rollers 44 and the traction means 37 is formed as a circulating endless traction means. It can be provided that one of the deflection means 35, 36 is coupled in motion with a drive 45, so that the pull means 37 can be moved around the two deflection means 35, 36 and thus the entrainment element 38 coupled to the traction means 37 can be moved along the longitudinal direction 34 of the tool holder 19.
    In order to be able to position or move bending tools 4 with a manipulation device 33 designed in this way, as shown in detail in FIG. 6 and FIG. 7, it is provided that a slot 46 is formed in the bending tool 4 and extends along one a bending edge 47 parallel direction 48 is angeord¬net. Such a slot 46 preferably extends over the complete length 49 of the bending tool 4.
    In order to be able to push or position the bending tool 4 in the longitudinal direction 34 of the tool holder 19, provision can be made for the pulling means 37 to run within the slot 46 of the bending tool 4. The traction means 37 can now be displaced so far in a direction 48 parallel to the bending edge 47 until a driver element 38, the bending tool 4 contacted and thus the bending tool 4 can be moved by the driver 38 in Längsausrich¬tung 34 in the tool holder 19.
    The bending tool 4 can in this case, as in an advantageous, in Fig. 6 dargestell¬ten, variant are executed. The slot 46, which is provided in the bending tool 4, preferably has a width 50 which is chosen so large that the traction means 37 can be passed without contact through the slot 46. The width 50 of the slot 46 is chosen so large that the Mitneh¬merelement 38 is not feasible through the slot 46 and thus can strike the Biege- tool and the bending tool 4 can move in motion.
    The slot 46 is preferably arranged in the bending tool 4 so that it is located within the tool clamping portion 51 of the bending tool 4. The tool clamping portion 51 is that part of the bending tool 4 which is adapted to receive and clamp the bending tool 4 in one of the tool holders 19, 20 can.
    The manipulation device 33 is preferably positioned such that at least one subsection 52 of the at least one traction means 37 is arranged within the clear cross section 53 of the slot-like tool holder 19, 20. Imlichten cross-section 53 of the tool holder 19, 20, the bending tool 4insinspecially the tool clamping portion 51 of the bending tool 4 is fixed and clamped.
    The tool clamping portion 51 is hereby completely received in the clear cross section 53. In order to ensure the functionality of the manipulation device 33 in the case of a bending tool arrangement as shown in FIG. 6, the light cross section 53 should preferably be executed with such a large depth 54 that a clearance remains below the tool clamping section 51 of the bending tool 4 in which the traction means 37 can be passed together with the Mitneh¬merelement 38. It can thereby be achieved that the driver element 38 can be positioned on one side of the ridge 48 bending tool 4 parallel to the bending edge 47 on the opposite side of the direction 48 of the bending tool 4 that is parallel to the bending edge 47. Thus, the bending tool 4 can be selectively pushed in a first or a second direction.
    As shown in Fig. 7, it can further be provided that in the bending tool 4 a recess 55 and two opposing recesses 55 are provided, which are arranged in the tool clamping portion 51 of the bending tool 4so that the driver element 38 can be received in such Ausneh-mung , The recess 55 is arranged so that in the tool clamping portion 51, the length 49 of the bending tool 4 is shortened by the recess 55. The recess 55 thereby represents a Vertie-fung which excludes the bending tool 4 in a direction 48 parallel to the bending edge 47.
    By means of this embodiment of the bending tool 4 shown in FIG. 7, it can be achieved that the driver element 38 can also be introduced between bending tools 4 which are arranged close to one another.
    Referring now to Fig. 2, the function of the manipulation device 33 can be described as follows.
    To set up the bending press 3, a bending tool 4 is removed from the tool store 31 by a first mani pulating device 30 and positioned in the insertion position 32 of the tool holder 19. Preferably, during this process, the engagement element 38 is arranged as close as possible to the second deflection means 36 so that it is located to the right of the insertion position 32.
    If the bending tool 4 has now been moved into its insertion position 32 by the first manipulation device 30 and positioned there, the second manipulation device 33, in particular the traction means 37, can be set in motion by the drive 45 in such a way that the entrainment element 38 moves in the direction of the first deflection means 35, and thus in the direction of insertion position 32 is moved. The traction means 37 in this case extends within the slot 46 of the bending tool 4 and can be moved freely until the driver element 38 comes into contact with the bending tool 4, in particular its tool clamping section 51. Now, due to the tensile force on the traction means 37, which is transmitted to the driver element 38, the bending tool 4 is set in motion. The bending tool 4 is now moved as far along the Längs¬ausrichtung 34 in the tool holder 19 until it has reached its vorbe¬stimmten position.
    In order to be able to use a further bending tool 4 in the tool holder 19, the driver element 38 must be moved again in the direction of the second deflection means 36 by means of the traction means 37 so that it is positioned as close as possible to another bending tool 4 in the insertion position 32 to use the tool holder 19 can. Now, the process of positioning the bending tool 4 in the steps described above is repeated.
    In order to be able to retrofit the bending press 3 after a successful bending operation, a possibility must be provided for removing the bending tools 4 again from the tool holder 19. For this purpose, several different Ausfüh¬rungsvarianten conceivable and presented.
    On the one hand, it may be provided that, as shown in FIG. 2, at least one of the two deflection means 35, 36 is displaceable transversely to the longitudinal alignment 34 of the tool holder 19. Preferably, in this case one or both deflection means 35, 36 are displaceable in a vertical direction, so that the driver element 38 can be brought down out of the engagement region of the bending tool 4, so that the driver element 38, as described in FIG. 6, is free under the bending tool 4 can be moved through.
    Thus, the traction means 37 together with the driver element 38 below the tool clamping portion 51 of the bending tool 4 can be brought freely running in the direction of the first deflection means 35. After this step, the deflection means 35, 36 can be moved upwards so that the driver element 38 is brought back into engagement with the bending tool 4. As a result, the bending tools 4 can be displaced by the traction means 37 or the entrainment element 38 in the direction of the second deflection means 36 and thus into the insertion position 32, from where they can be removed with the first manipulation device 30.
    By means of the recesses 55 in the bending tool 4 shown in FIG. 7, it can be achieved that not all bending tools 4 used in the tool holder 19 are displaced simultaneously in the direction of the second deflection means 36, but it can also be provided that the Mitnehmerele¬ment 38 between individual bending tools 4 is positioned and thus nureinzelne bending tools 4 are displaced in the direction of the second deflection means 36.
    For vertical positioning of one or both deflection means 35, 36 it can be provided that these are arranged on a vertically extending guide rail 56. In this case, for example, an electromotive, ahydraulic or a pneumatic adjusting drive 57 can be used as drive means.
    The second manipulation device 33 shown in FIG. 2 preferably extends approximately over a total length 58 of the tool holder 19. Thus, the working range of such a manipulation device 33 can be made as large as possible, so that the bending tools 4 are positioned as close as possible to each respective position the tool holder 19 can be positioned. Flierzukann it may be necessary that the two deflection means 35, 36 are partially positioned outside of the tool holder 19 in order to make the working area of the Manipula¬ tion device 33 as large as possible. Alternatively, it may be provided that, for example, the second deflecting means 36 is arranged so that it does not project laterally of the tool holder 19 in order not to obstruct a tool store 31 arranged next to the bending press 3.
    FIG. 8 shows a further embodiment of the production plant 1, which may be independent of itself, and in which again identical reference numerals or component designations are used for the same parts as in the preceding FIGS. 1 to 7. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1-7. Referenced.
    The embodiment variant of the production plant 1 shown in FIG. 8 is basically similar to the embodiment variant as shown in FIG. 2. Unlike the embodiment variant shown in FIG. 2, in this case the manipulation device 33 is designed over a larger width. In this case, the manipulation device 33 extends over such a large width that the working region of the manipulation device 33 also extends beyond the tool storage 31 arranged next to the bending press 3. It can be provided that a tool-collecting device 59 is provided in the tool storage 31, in which a plurality of bending tools 4 can be inserted simultaneously. This tool collecting device 59 can finally be moved into a storage area of the tool storage 31. Thus, individual bending tools 4 can be prepared together in such a tool collecting device 59.
    Advantageous in the variant shown in Fig. 8 with an extended Manipula¬tionsvorrichtung 33 is not shown by the first manipulation device 30, as shown in the embodiment in Fig. 2, each bending tool 4 individually in the insertion 32 must be moved, but that several indians Tool collecting device 59 pre-equipped bending tools 4 can be moved simultaneously into the tool holder 19, 20.
    By means of these measures, time can be saved during the set-up process, since a plurality of bending tools 4 are simultaneously removed or transported by means of the tool-collecting device 59. For example, it may be provided that the tool-collecting device 59 is pre-loaded with bending tools 4 and the tool-collecting device 59, together with the bending tools 4 accommodated therein, is subsequently positioned at its predetermined position for tooling next to the tool holder 19. Subsequently, all the bending tools 4 positioned in the tool collecting device 59 can be simultaneously displaced into the tool holder 19.
    In order now to equip the next bending tools 4 in the bending press 3, a new tool collecting device 59 with already pre-equipped bending tools 4 next to the tool holder 19 can be positioned by means of the first manipulating device 30. According to the above steps, the bending tools 4 can now be displaced into the tool holder 19 by means of the second manipulation device 33.
    A tool-collecting device 59, as shown in Fig. 9, must be carried out so that it is open at the bottom, in order to lift the tool-collecting device 59 together with the bending tools 4 received therein upward. The pulling means 37 could not raise a tool collecting device 59, which is designed to be closed downwards.
    In the embodiment variant from FIG. 9, two traction means 37, 60 are shown, which run parallel to one another, and whose mode of operation is explained in greater detail in further sequences.
    In the embodiment, which is shown in Fig. 8, a second traction means 60 is further shown in the line-ter-ter execution, on which a second driver element 61 is arranged. By means of such an embodiment it can be achieved that the bending tools 4 can be displaced in a first direction 62 by means of the first traction means 37 and can be displaced in a second direction 63 by means of the second traction means 60. It can be provided that the two driver elements 38, 61 can each be arranged on one side of the longitudinal alignment 34 on the bending tools 4. This design makes it possible for none of the driver elements 38, 61 to be displaced in the longitudinal direction 34 onto the opposite side of the bending tools 4. As a result, the guide rail 56 or the adjusting drive 57 described in an alternative variant can also be omitted.
    Fig. 10 shows a schematic representation in which the deflection means 35, 36 are designed as a multi-wound spindle. This represents a further embodiment variant for the design of the deflection means 35, 36, and can be used in combination with the embodiment variants described above.
    11 shows a schematic diagram of a further embodiment in which the deflection means 35, 36 are designed as cable drums 64. In this case, the traction means 37 is alternately wound on one of the cable drums 64, whereby the driver element 38 can be displaced along the longitudinal alignment 34 in the tool holder 19. The two cable drums 64 must be coordinated with each other in their rotational speed.
    12 shows in a schematic representation a further embodiment of the manipulation device 33 in which a guide element 65 is provided which can lift the traction means 37 and thus bring the entrainment element 38 attached to the traction means 37 into engagement with a bending tool 4. It can thereby be achieved that the two deflection means 35, 36 do not have to be adjusted with respect to their horizontal position. Only the horizon¬ tale distance of the two deflection means 35, 36 must be adapted to the adjustment of Zugmit¬tels 37. Such a guide element 65 can be designed, for example, as a guide rail, which can be lifted in the vertical direction in order to bring the driver element 38 into engagement with the bending tool 4. Alternatively, it can be provided that the Führungsele¬ment 65 is formed approximately by two pulleys, which can lift the traction means.
