    专利说明:

    The present invention relates to a device, which allows transporting flat objects stacked in bundles through a machine in charge of connecting each of these bundles.
    The invention finds a particularly advantageous application in the field of packaging.
    In the packaging industry, the manufacture of folding boxes is traditionally done in line, folding and pasting cutouts by means of machines commonly called folder-gluing machines. Generally, the folding boxes are released in the form of a continuous flow, so it is relevant to pack them in bundles, since when these boxes are destined to be stored before their first use.
    In this logic, it is known to pack folding boxes in the form of streaked bundles, that is, stacks of boxes that are individually connected via one or more links. Different types of percinting means can be used to complete this task, according to the fact that, for example, it is desired to tie each bundle with string by means of at least one thin link, such as a string, to percint each bundle through at least at least one narrow link, such as a leaf or to flag each bundle, thanks to the use of at least one wide link, such as a strip.
    In a standard punching machine, two zones are more particularly important. This is initially the assembly area that is located at the entrance of the machine, and which is used to form each beam. And then there is the percinting zone which is positioned more in the center of the machine, and which is dedicated to connecting each beam. Naturally, a transport device is provided to ensure the individual displacement of each beam through the punching machine, notably from the mounting area to the punching area.
    In practice, this shift is traditionally carried out in two stages, in order to have reduced cycle times. This characteristic implies the existence of an intermediate zone, namely a transfer zone that is logically located between the assembly zone and the percinting zone. Regardless of what it is, it is for this reason that this type of transport device usually employs two different means of transport.
    Concretely, first means of transport ensure the displacement of each beam from the assembly zone to the transfer zone, while second means of transport carry the displacement of that beam from the transfer zone to the percinting zone. In this logic, the vocation of the first means of transport is, first of all, to quickly release the assembly area in order to be able to start the formation of a new beam more quickly. That of the second means of transport, on the contrary, is to feed the means of percinting with bundles and this without dead time.
    In this regard, it is known by the state of the art of a percinting machine that serves to connect folding boxes together in bundles and that has this bundle transport device. In this machine, the formation of each bundle is operated by successive deposits of batches of boxes, in the middle of four guides in the form of corners that are arranged vertically in the four corners of the stack. The two lower guides are provided with movable stops, the concealment of which allows the beam to be pulled forward. The first means of transport consist of a pneumatic handle that is able to push a bundle from the rear, when it is complete in order to extract it from the guides and take it to the second means of transport. These second means of transport are presented in the form of an association of conveyor belts that is composed of a horizontal conveyor and two vertical conveyors and an upper conveyor that all rotate in the same direction and at the same speed.
    This type of transport device, however, has the drawback of being complicated to adjust, both in terms of the position of the guides in the assembly area, as well as the synchronization of the conveyors of the second means of transport.
    Another major disadvantage of this transport device is that it proves to be insufficiently precise in terms of orientation. The low efficiency of the vertical guides in the assembly area is particularly noteworthy here, when the pneumatic puller is put into action, but also on that of the conveyor belts, considering the friction that appears, no doubt, when the bundles pass.
    Also, the technical problem to be solved by the object of the present invention is to propose a transport device for the displacement in the middle of a percinting machine, a succession of bundles composed of stacked flat objects, comprising that first means of transport in conditions to move each beam from a mounting zone, in which that beam is formed from a stack of flat objects, to a transfer zone in which that beam is positioned outside the mounting zone, as well as second means of transport under conditions to move each bundle from the transfer zone to a percinting zone, in which the flat objects that make up that bundle are linked together, a transport device that would avoid the problems of the state of the art, offering noticeably increased efficiency, all being more easy to regulate.
    The solution to the technical problem presented consists, according to the present invention, in the fact that the first means of transport are, moreover, able to orient longitudinally the stacking of flat objects, when the formation of each beam in the assembly area, and the maintain this beam longitudinally when moving from the mounting area to the transfer zone.
    It is important to underline that the invention applies to any punching machine, regardless of the connection technique used. A transport device according to the invention can, in effect, independently equip a machine capable of tying each bundle with string, by means of at least one thin link, such as a string, a machine in charge of percepting each beam through at least one narrow link, such as a sheet, a machine capable of flagging each beam, thanks to the use of at least one wide link, such as a strip, or more generally a machine capable of individually connecting each beam by any combination of links of any nature and dimensions. This means, in common terms, that the punching machine can notably be a string maker, a stripper or a flagger.
    Regardless of what it is, the invention, as so defined, has the advantage of guaranteeing an extremely precise displacement of the bundles, through the percinting machine. Indeed, in addition to their classic transport function, the first means of transport play two other supplementary roles that are, however, complementary to their transport function. It is more particularly a guiding role that is maintained when the bundles are formed, and a maintenance role that is ensured during the displacement of those bundles.
    The present invention also refers to the characteristics that will stand out in the course of the description to be made below and which should be considered in isolation or according to all possible technical combinations.

    For the sake of clarity, the same elements have been designated by identical references. Likewise, only the essential elements for understanding the invention have been represented, and this without regard for scale and schematically.
    Figures 1 to 6 illustrate a punching machine 100 which is intended to integrate as a module in a packaging machine designed to transform a continuous flow of folding boxes from a folder-gluer, into a succession of punched bundles ready to be handled and / or stored.
    As its name implies, the punching machine 100 is more particularly in charge of connecting stacks of folding boxes, forming bundles 2, 3 that are formed upstream of that machine 100, in this case, at the level of a connecting table 110. To exercise its The punching machine 100 has a punching unit 120 that is able to connect flat objects of each bundle 2, 3 together and that is permanently integrated in a compartment 130 located at the exit of the connection table 110. Once punched , bundles 2, 3 are then placed at the level of a receiving table 140 which is positioned directly downstream of compartment 130.
    Thus, as can be seen in the figures as a whole, the displacement of the bundles 2, 3 of folding boxes through the sweeping machine 100 is ensured by a transport device 1. This is initially provided with first transport means 10 which are responsible for moving each bundle 2, 3 of a mounting zone in which that bundle 2, 3 is formed from a stack of folding boxes (figure 2), to a transfer zone in which that bundle 2, 3 is positioned outside the bundle zone assembly (figure 3). But the transport device 1 is also provided with second transport means 40 which are designed to move each bundle 2, 3 from the transfer zone to a percinting zone, in which the flat objects that make up that bundle 2, 3 are connected together (figure 4).
    According to the object of the present invention, the first means of transport 10 are, moreover, able to orient the stacking of the folding boxes longitudinally, when forming each bundle 2, 3 in the assembly area, but also to maintain longitudinally this beam 2, 3, when moving from the mounting area to the transfer zone.
    According to the particularity of the invention, the first means of transport 10 are initially provided with at least one driving element 11,12 which is able to be positioned at the rear of each beam 2, 3, placed in the mounting area (figure 2 ), and pushing it to the transfer zone (dotted in figure 2), before concealing (figure 3) to return to its initial position (figures 4 and 5). But the first means of transport 10 are also provided with at least one maintenance element 21, 22 which is able to be positioned in front of each beam 2, 3 placed in the mounting area (figure 2), and to advance until the transfer zone concomitantly in relation to each pusher element 11.12 (stipulated in figure 2), before concealing (figure 3) to return to its initial position (figures 4 and 5).
    Particularly advantageously, each pusher element 11, 12 is able to be dragged in displacement parallel to the axis of the punching machine 100, by means of a drive mechanism 13 which is positioned under the space, through which the beams 2 pass, 3 in the middle of this punching machine 100.
    In this logic, the set is adjusted so that each driving element 11, 12 can slide downwards, in a substantially vertical direction, as shown in figure 3.
    In this example of realization, two driving elements 11, 12 are listed, which are implanted symmetrically on both sides of the axis of the punching machine 100 (figure 1). Concretely, each driving element 11, 12 is presented in the form of a vertical bar that is mounted transversely movable in translation, in a direction parallel to the machine axis, by means of the drive mechanics 13. For this, each vertical bar is supported by a carriage 14 that is attached to a toothed belt 15 stretched between a transmission cylinder 16 and a drive shaft 17 coupled to an electric motor (not shown). In order that each driving element 11,12 can, on the other hand, slide vertically downwards, each vertical bar is, moreover, mounted longitudinally movable in translation in relation to the carriage 14 that supports it, in a direction substantially perpendicular to the axis of machine 100 (figure 3).
    According to another advantageous feature, each maintenance element 21, 22 is able to be driven in movement parallel to the axis of the punching machine 100, by means of a drive mechanism 23, which is positioned under the space through which they pass bundles 2, 3.
    In this logic, the set is adjusted so that each maintenance element 21, 22 can hide downwards in a substantially vertical direction.
    Analogously to what has been said about the driving elements 11, 12, two maintenance elements 21, 22 are listed, which are implanted symmetrically on both sides of the axis of the punching machine 100 (figure 1). Each maintenance element 21,22 is in the form of a vertical bar that is mounted transversely movable in translation, in a direction parallel to the machine axis, using drive mechanics 23. For this, each vertical bar is supported by a carriage 24 which is fixed on a toothed belt 25 stretched between a transmission cylinder 26 and a drive shaft 27 coupled to an electric motor (not shown). In order to be able to retract vertically downwards, each maintenance element 21, 22 is, on the other hand, mounted longitudinally movable in translation, in relation to the carriage 24 that supports it, in a direction substantially perpendicular to the axis of the machine 100 ( figure 3).
    According to a further feature of the invention, the first means of transport 10 comprise, in addition, two lateral guides 31,32 which extend on both sides of the space, through which the beams 2, 3 pass in a length that goes substantially from the mounting area to the transfer zone. The set is, on the other hand, adjusted so that the two lateral guides 31,32 are in a position to, on the one hand, orient the stacking of the folding boxes transversely when each bundle 2, 3 is formed in the assembly area, and, on the other hand, to keep that beam 2, 3 across, when moving it from the mounting area to the transfer zone.
    In a particularly advantageous manner, at least one side guide 31, 32 is mounted adjustable in position in a transverse direction. This implies that the lateral guide 31, 32 in question is mounted movable in transversal translation and that it is coupled to adjustment means, allowing to precisely adjust its position.
    According to a currently preferred embodiment of the invention, each side guide 31, 32 consists of a grid which extends substantially from the mounting area to the transfer zone.
    As can be seen clearly in the different figures, each grid comprises a plurality of parallel pins that extend, in a substantially vertical manner, with their ends oriented upwards.
    This structure proves to be particularly advantageous, provided it is combined, as in this example of realization, with the use of a clamp 200 of a palletizing robot (not shown). This clamp 200 will be chosen so as to have pins 210, the deviation of which is compatible with those of the grid pins. The clamp 200 will then be in a position to deposit lots of folding boxes between the two gratings, descending in a substantially vertical manner, with the body of this clamp positioned outside the assembly area, and the clamps 210 pointing inwards. The collet 200 can then be removed, moving it substantially to the horizontal, in a transverse direction in relation to the machine axis.
    According to another feature of the invention, the second means of transport 40 are entirely provided with at least one bundle 41, 42 which is able to be positioned at the rear of each bundle 2, 3, placed in the transfer zone (figure 3 ), and propel it to the percinting zone (figure 4), before concealing itself to return to its initial position (figure 5). On the other hand, the second means of transport 40 are also provided with two lateral guides 51,52 that extend on both sides of the space, through which the bundles 2, 3 pass, in a length that goes substantially from the transfer zone the streak zone (figure 1). Finally, the second means of transport 40 have, moreover, at least one pressing element 61, 62 which is arranged above the space, through which the bundles 2, 3, which go from the transfer zone to the percinting zone, pass through. The assembly is adjusted so that each pressing element 61, 62 is in a position to press vertically each bundle 2, 3 that circulates in the previously defined transit space (dotted in figure 2 and figure 4).
    Particularly advantageously, each bundle 41,42 is able to be dragged in displacement parallel to the axis of the punching machine 100, by means of a drive mechanism 43, which is positioned above the space through which the bundles 2, 3 pass. in the middle of the punching machine 100.
    In this logic, each driving element 41, 42 is adjusted in order to be able to hide upwards, in a substantially vertical direction.
    In this example, two booster elements 41, 42 are also listed here, which are implanted symmetrically on both sides of the punching machine axis 100. Specifically, each booster element 41,42 is presented in the form of a vertical bar that is mounted transversely movable in translation, in a direction parallel to the machine axis, by means of drive mechanics 43. For this, each vertical bar is suspended in a trolley 44 that is fixed on a toothed belt 45 stretched between a transmission cylinder 46 and a drive shaft 47 coupled to an electric motor (not shown). In order that each driving element 41, 42 can, on the other hand, slide vertically upwards, each vertical bar is, moreover, mounted longitudinally movable in translation, in relation to the carriage 44 that supports it, in a direction substantially perpendicular to the machine axis 100.
    According to another advantageous feature, at least one lateral guide 51,52 is mounted, adjustable in position in a substantially transverse direction. This means, in other words, that the referred lateral guide 51, 52 is mounted movable in transverse translation, and that, on the other hand, it is coupled to adjustment means, allowing to precisely adjust its position.
    In this embodiment, the side guides 51, 52 are two in number. According to figure 1, they are implanted symmetrically on both sides of the axis of the punching machine 100, and are presented in the form of two parallel vertical plates.
    According to an advantageous feature of the invention, at least one pressing element 61, 62 is mounted adjustable in position, in a substantially transverse direction.
    In this example of realization, two pressing elements 61, 62 are listed again, which are symmetrically implanted on both sides of the axis of the punching machine 100, as can be seen in figure 1. Specifically, each pressing element 61, 62 is in the form of a substantially horizontal bar which is mounted transversely movable in translation, in a direction substantially perpendicular to the machine axis.
    Naturally, the invention relates more generally to any punching machine 100, capable of connecting together flat objects packed in bundles 2, 3 and comprising at least one transport device 1, as previously described.
