The invention relates to a pile cutting apparatus with a support element.
Pile cutting apparatuses that have a lowerable upper blade and a stationary lower blade are known. In this way, multiple-up piles are detached from sheet piles. A cutting edge of the upper blade has to be lowered at least a certain distance below a cutting edge of the lower blade for the cutting operation to be carried out completely. In particular when an edge is trimmed, it is possible for the part of the bottommost sheet which protrudes beyond the lower blade to sag downwardly. When the cutting edge of the upper blade is then guided past the cutting edge of the lower blade, the bottommost sheet may be bent around the cutting edge of the lower blade, especially when the sheets are thin. As a result, the bottommost sheet is not cut cleanly, but, for example, only a layer thereof is scraped off. What remains is a part at the bottommost sheet, which is actually to be detached, causing problems during further processing.
A pile cutting apparatus comprising a cutting device is known from EP 1 018 408 A1, which has a guide plate that can be pivoted about an axis and by means of which a detached multiple-up pile can be held in shape laterally when the pile is being moved into a raised position after a cutting operation.

It is the object of some examples herein to provide a pile cutting apparatus with a support element.
The object is achieved according to some examples herein by a pile cutting apparatus that includes at least one first cutting device for cutting at least one sheet pile; at least one first front bearing device having a first front pile bearing surface; and at least one first rear bearing device having a first rear pile bearing surface. The first rear pile bearing surface is used to carry at least one respective detached intermediate pile or multiple-up pile. A cutting gap is provided between the first front pile bearing surface and the first rear pile bearing surface. A first table plane contains the first front pile bearing surface. The first cutting device includes at least one movable upper blade and at least one lower blade including a cutting edge. The first cutting device further includes at least one first cutting aid for fixing sheet piles, which is arranged to be movable at least with respect to a vertical direction, and which is arranged upstream from the first upper blade along a transport path provided for transport of sheet piles and/or intermediate piles and/or multiple-up piles. The first cutting device includes at least one movable support element, which has at least one contact surface provided for supporting sheets and which is arranged to be movable at least between a support position and at least one first disposal position. The at least one support element, at least in the support position, is arranged between the first front pile bearing surface and the first rear pile bearing surface. The at least one contact surface of the support element, when the support element is arranged in the support position, is arranged in and/or beneath the first table plane. The at least one contact surface of the support element is arranged closer to the cutting edge of the bottom blade when the support element is arranged in the support position than when the support element is arranged in the disposal position.
A pile cutting apparatus comprises at least one in particular first cutting device for cutting at least one pile of sheets, in particular a cutting device for cutting piles of sheets to yield multiple-up piles. The pile cutting apparatus comprises at least one first front bearing device having a first front pile bearing surface. A first at least temporarily horizontal table plane contains this first front pile bearing surface at least partly, and preferably completely. The in particular first pile cutting apparatus preferably comprises at least one first rear bearing device having a first rear pile bearing surface. A cutting gap is preferably provided between the first front pile bearing surface and the first rear pile bearing surface. The in particular first pile cutting device has at least one movable upper blade and at least one in particular stationary lower blade. The lower blade preferably has a cutting edge. The first cutting device preferably has at least one first cutting aid for fixing piles of sheets, which is arranged so as to be at least movable with respect to a vertical direction and which is arranged in front of the first upper blade along a transport path provided for transporting piles of sheets and/or intermediate piles and/or multiple-up piles.
The in particular first pile cutting device comprises at least one movable support element, which has at least one contact surface for supporting sheets, in particular from beneath, and which is arranged so as to be movable, for example switchable, in particular pivotable, between a support position and at least one first disposal position. The at least one contact surface of the support element is arranged in and/or beneath the first table plane when the support element is arranged in the support position. The at least one contact surface of the support element is arranged closer to an in particular stationary and/or lower cutting edge of the lower blade when the support element is arranged in the support position than when the support element is arranged in the disposal position. This offers the advantage that even a very short end of a bottommost sheet of the pile can be propped from beneath to prevent this end from being folded when the upper blade is lowered and being only partly scraped off, instead of being cleanly detached. In addition, it can be ensured that the sheet end during forward feeding does not inadvertently end up in a clearance, which is necessary to create space for the upper blade. Preferably, the at least one contact surface of the support element is at least partly, and more preferably completely, arranged beneath the first table plane when the support element is arranged in the disposal position.
In one refinement, the pile cutting apparatus is characterized in that the support element is arranged pivotably about a switching axis. This offers the advantage that a relatively simple movement is carried out and only little installation space is required.
In an alternative or additional refinement, the pile cutting apparatus is preferably characterized in that the first cutting device comprises at least one bridge element, which in particular differs from the support element and which can be moved between at least one transfer position and at least one interruption position. The bridge element preferably has at least one prop surface. It is preferable that the prop surface is preferably completely located in the first table plane and/or has a vertical normal vector when the bridge element is arranged in the transfer position. When the bridge element is arranged in the interruption position, the prop surface thereof is preferably located at least 50%, more preferably at least 75%, still more preferably at least 95%, and still more preferably at least 99% outside the first table plane and/or has a normal vector that deviates from a vertical direction. This offers the advantage that even components of the sheet piles which are to be detached and further processed can be delivered properly to a subsequent bearing surface, and the advantages of the support element are nonetheless preserved.
In an alternative or additional refinement, the pile cutting apparatus is preferably characterized in that the at least one bridge element is arranged pivotably about a pivot axis. This offers the advantage that a relatively simple movement is carried out and only little installation space is required. In an alternative or additional refinement, the pile cutting apparatus is preferably characterized in that the at least one support element and the at least one bridge element are rigidly connected to one another and/or can be pivoted together about the switching axis. This offers the advantage that only one drive system is necessary to carry out both movements.
In an alternative or additional refinement, the pile cutting apparatus is preferably characterized in that the first cutting device comprises at least one shielding element, which can be moved between at least one shielding position and at least one release position. When the shielding element is arranged in the shielding position thereof, the shielding element is preferably at least partly arranged above the first table plane. The shielding element is preferably arranged completely beneath the first table plane when the shielding element is arranged in the release position thereof. This offers the advantage that scrap pieces only occur in regions intended for this purpose. The at least one shielding element is preferably rigidly arranged relative to the at least one support element and/or is rigidly arranged with respect to the at least one bridge element. It is then, in turn, possible to utilize a shared drive.
In an alternative or additional refinement, the pile cutting apparatus is preferably characterized in that a surface normal of the contact surface of the support element forms an angle with a surface normal of the prop surface of the bridge element which is at least 30°, more preferably at least 45°, still more preferably at least 60°, and still more preferably at least 80°, and which is no more than 150°, more preferably no more than 135°, still more preferably no more than 120°, and still more preferably no more than 100°. This offers the advantage that, depending on the pivoted position, the support element or the contact element is employed, and the respective other element does not block the path.
The at least one support element, at least in the support position thereof, and preferably always, is arranged between the first front pile bearing surface and the first rear pile bearing surface, in particular along a transport path provided for sheet piles. As a result, only little installation space is required.
In an alternative or additional refinement, the pile cutting apparatus is preferably characterized in that the first pile cutting device has at least one lowerable cutting aid for pressing a part of a respective sheet pile against the first front pile bearing surface and/or that the first pile cutting device comprises at least one lowerable hold-down device for pressing a part of a respective sheet pile, in particular a part to be detached, against the first rear pile bearing surface. This enables an especially clean cut.
In an alternative or additional refinement, the pile cutting apparatus is preferably characterized in that a guide surface for influencing a drop path of detached pile components is arranged beneath the upper blade. Scrap pieces can then be transported especially easily along a path provided for them, for example into a waste container.
An exemplary embodiment of the invention is illustrated in the drawings and will be described in greater detail below. The drawings show:
A pile cutting apparatus 01 for cutting sheet piles 26 into multiple-up piles 27, in particular securities piles 27, preferably comprises at least one in particular first cutting device 13, which is also referred to as an in particular first pile cutting device 13. The first cutting device 13 is preferably designed as a first cutting device 13 for cutting at least one sheet pile 26, in particular for cutting sheet piles 26 into multiple-up piles 27.
In addition to the first cutting device 13, the pile cutting apparatus 01 preferably comprises at least one second cutting device 14, which is also referred to as an in particular second pile cutting device 14. By providing multiple cutting devices 13; 14, unnecessary multiple pivoting of the corresponding piles can be dispensed with, and the throughput can be increased.
The first cutting device 13 preferably comprises at least one first knife bar 16, at which a first cutting blade 18 is arranged, which is referred to as a first upper blade 18. The first upper blade 18 preferably has a first upper cutting edge 21, which is preferably designed as a linear cutting edge 21. A respective cutting edge 21; 22; 81 is preferably an in particular straight line at which two surfaces of a corresponding cutting blade 18; 19; 77 come together and which is designed to sever or detach material. The first knife bar 16 is preferably arranged so as to be movable along a preferably linear, and more preferably exclusively linear, first adjustment path, in particular in and/or counter to a first adjustment direction A1.
The pile cutting apparatus 01 comprises at least one first front bearing device 11 having a first front pile bearing surface 04. It is in particular assigned to the first cutting device 13. The first front bearing device 11 is also referred to as a first front table 11. A first table plane E contains this first front pile bearing surface 04, preferably completely, at least to the extent that this pile bearing surface 04 has a planar design. This must be distinguished from an imaginary plane that only intersects the pile bearing surface 04, that is, only shares an intersecting line with the same. The first table plane E is preferably at least temporarily, in particular at least during cutting operations, and more preferably permanently horizontally oriented. The first front pile bearing surface 04 is used, in particular, to carry a sheet pile 26 to be cut prior to a respective cutting operation and/or during a respective cutting operation. The first pile cutting device 13 comprises at least one movable first upper blade 18 and at least one, in particular stationary, cutting blade 77 designed as a first lower blade 77. The first lower blade 77 preferably has a cutting edge 81, which is referred to as a lower cutting edge 81. For example, at least a part of the first lower blade 77 forms a part and/or a continuation of the first front pile bearing surface 04. For example, the cutting edge 81 of the first lower blade 77 forms a delimitation of the first front pile bearing surface 04 and/or the cutting edge 81 of the first lower blade 77 is arranged in front of the cutting gap 76, based on the transport path provided for the sheet pile 26.
The pile cutting apparatus 01 preferably comprises at least one first rear bearing device 68 having a first rear pile bearing surface 69. The first rear pile bearing surface 69 is used to carry at least one respective detached intermediate pile 28 or multiple-up pile 27. A cutting gap 76 is preferably provided between the first front pile bearing surface 04 and the first rear pile bearing surface 69. This cutting gap 76 extends along the transport path provided for sheet piles 26, for example over at least 2 cm, preferably at least 4 cm, and more preferably at least 6 cm and, independently thereof, for example, over no more than 20 cm, more preferably no more than 10 cm, and still more preferably no more than 8 cm. This cutting gap 76 is used in particular to be able to lower the first upper blade 18 to beneath the first table plane E and/or to receive at least one support element 78 and/or at least one bridge element 83 and/or at least one shielding element 86 and/or at least one switching device 89 and/or to transport away scrap pieces 91. The first table plane E preferably contains this rear pile bearing surface 69 at least partly, and in particular completely. Sheet piles 26 can then lie flat for cutting.
The first pile cutting device 13 comprises at least one movable support element 78, which has at least one contact surface 79 for supporting sheets 71, in particular from beneath. The at least one support element 78 is arranged so as to be movable, in particular switchable, and preferably pivotable between a support position and at least one first disposal position. The contact surface 79 is preferably at least partly designed as a planar contact surface 79. The at least one contact surface 79 of the support element 78 is arranged in and/or beneath the first table plane E at least when the support element 78 is arranged in the support position. In particular, no component of the contact surface 79 of the support element 78 is arranged above the table plane E when the support element 78 is arranged in the support position. The at least one contact surface 79 of the support element 78 is arranged closer to the in particular stationary cutting edge 81 of the lower blade 77 when the support element 78 is arranged in the support position than when the support element 78 is arranged in the disposal position. The distance to be considered in each case is the smallest possible distance. Preferably, the at least one contact surface 79 of the support element 78 is at least partly, and more preferably completely, arranged beneath the first table plane E when the support element 78 is arranged in the disposal position.
For example, the at least one support element 78 is arranged pivotably about a switching axis 82, in particular in order to be switched between different positions. Such positions are, for example, an intake position and/or the support position and/or the first disposal position and/or a second disposal position.
The intake position of the support element 78 is used, in particular, to be able to position an edge region 92 of a sheet pile 26 to be cut off relative to the lower blade 77 and/or the upper blade 18 of the first cutting device 13 in such a way that an edge can be trimmed thereafter. During the edge trimming process, the support element 78 should be spaced a distance apart from the lower blade 77 so that the cutting edge 21 of the upper blade 19 can be moved, in particular lowered, at least a certain distance beneath the cutting edge 81 of the lower blade 77 and/or beneath the first table plane E. This results in a clearance, which constitutes part of the cutting gap 76. The clearance extends along the transport path provided for sheet piles 26, for example over at least 2 mm, and preferably at least 4 mm and, independently thereof, for example, over no more than 20 mm, more preferably no more than 10 mm, and still more preferably no more than 8 mm. However, the edge region 92 of the sheet pile 26 must pass this clearance during the positioning of the pile. The risk would then be that at least the edge of the bottommost sheet 71 could slide into the clearance and thus not be supported by the support element 78. For this reason, first the support element 78 is positioned in the intake position, then the sheet pile 26 is positioned relative to the lower blade 77 and/or the upper blade 18 of the first cutting device 13, and then the support element 78 is moved, in particular lifted and/or pivoted, into the support position. If necessary, a part of the sheets 71 of the sheet pile 26 to be cut is lifted. The at least one contact surface 79 of the at least one support element 78 is preferably arranged beneath the first table plane E and closer to the cutting edge 81 of the lower blade 77 when the support element 78 is arranged in the intake position than when the support element 78 is arranged in the disposal position. The at least one contact surface 79 of the at least one support element 78 is arranged closer to the cutting edge 81 of the lower blade 77 when the support element 78 is arranged in the support position than when the support element 78 is arranged in the intake position. (The support element 78 is shown in the intake position thereof by way of example in
The support position of the support element 78 is used, in particular, to prop at least the bottommost sheet 71 of a sheet pile during an edge cutting operation and to thereby prevent this sheet 71 from not being cut completely. For this purpose, the contact surface 79 of the support element 78 arranged in the support position is preferably contained in the first table plane E or arranged in a manner that only deviates slightly therefrom. (The support element 78 is shown in the support position thereof by way of example in
The first disposal position of the support element 78 is used, in particular, to dispose of scrap pieces 91, in particular cut-off edge pieces of the sheet pile 26 too small to be further processed. For this purpose, the support element 78 is preferably moved into the first disposal position thereof, in which the contact surface 79 thereof is essentially arranged completely outside the first table plane E. The contact surface 79 of the support element 78 is preferably obliquely arranged in the first disposal position. This preferably causes the cut-off edge pieces to slide off the support element 78. For example, this already suffices for removal. Otherwise, the support element 78 can be moved even further, in particular into the second disposal position, for example in order to create more space or widen a constriction. The second disposal position of the support element 78 is accordingly used in particular for a safe removal of the cut-off edge pieces of the sheet pile 26. (The support element 78 is shown in the first disposal position thereof by way of example in
The switching axis 82 is preferably horizontally oriented. The switching axis 82 preferably extends in a transverse direction A. The transverse direction A is preferably the direction A parallel to which the cutting edge 81 of the lower blade 77 extends. The switching axis 82 is preferably located beneath the table plane E. For example, the switching axis 82 is located in the cutting gap 76 and/or along a transport path provided for sheet piles 26 downstream from the first front pile bearing surface 04, in particular between the first front pile bearing surface 04 and the first rear pile bearing surface 69, more preferably closer to the first rear pile bearing surface 69 than the first front pile bearing surface 04. Preferably, at least one pivot drive for pivoting the at least one support element 78 is provided. The at least one pivot drive is designed, for example, as an electric motor and/or as a linear motor and/or as a pneumatic drive and/or as a hydraulic drive. In a preferred embodiment, the at least one pivot drive is designed as a pair of pneumatic cylinders arranged in series. A first pneumatic cylinder is accordingly attached with the components thereof that can be moved with respect to one another to a part of the cutting apparatus which is fixed to the frame on the one hand, and to a second pneumatic cylinder on the other hand. The second pneumatic cylinder is connected with the components thereof that can be moved with respect to one another to the first pneumatic cylinder on the one hand, and to a pivotable part on the other hand, which is the support element 78 or is rigidly connected to the support element 78. By a corresponding activation of the respective two end positions of the two pneumatic cylinders, it is then possible to implement four positions of the support element, in particular the intake position, the support position, the first disposal position, and the second disposal position.
In an alternative or additional refinement, the pile cutting apparatus 01 is preferably characterized in that the first cutting device 13 comprises at least one bridge element 83, which can be moved, in particular switched, and for example pivoted, between at least one transfer position and at least one interruption position. The bridge element 83 preferably has at least one prop surface 84. When the bridge element 83 is arranged in the transfer position, the prop surface 84 thereof is located, preferably completely, in the first table plane E and/or the prop surface 84 thereof has a vertical normal vector N84. When the bridge element 83 is arranged in the interruption position, the prop surface 84 thereof is located at least 50%, preferably at least 75%, more preferably at least 95%, and still more preferably at least 99% outside the first table plane E and/or the prop surface 84 thereof has a normal vector N84 that deviates from a vertical direction V. For example, the at least one bridge element 83 is arranged pivotably about a pivot axis 82, in particular in order to be switched between different positions. Such positions are the transfer position and the at least one interruption position, for example. This pivot axis 82 is preferably the switching axis 82. The transfer position of the bridge element 83 is used in particular to securely guide a leading edge of a sheet pile 26, of which a part intended for further processing as an intermediate pile 28 or multiple-up piles 27 is to be cut off, onto the second pile bearing surface 69. For this purpose, the surface normal N84 of the prop surface 84 of the bridge element 83, when the same is in the transfer position, is preferably vertically oriented and/or the prop surface 84 of the bridge element 83, when the same is in the transfer position, is preferably contained in the first table plane E. The at least one interruption position of the bridge element 83 is used in particular to enable an adaptation of the position of the support element 78 and/or to create space for movements or repositioning of the support element 78. For example, the bridge element 83 can be arranged in several different interruption positions. The cutting gap 76 can preferably be at least partly covered by the bridge element 83. The cutting gap 76 can preferably be at least partly covered by the support element 78. The cutting gap 76 can preferably only be covered either by the bridge element 83 or by the support element 78 at any time or by neither of the two.
In an alternative or additional refinement, the pile cutting apparatus 01 is preferably characterized in that the at least one support element 78 and the at least one bridge element 83 are rigidly connected to one another. The at least one support element 78 and the at least one bridge element 83 are preferably arranged so as to be pivotable together about the switching axis 82. Preferably, a surface normal N79 of the contact surface 79 of the support element 78 forms an angle W with a surface normal N84 of the prop surface 84 of the bridge element 83. This angle W is preferably at least 30°, more preferably at least 45°, still more preferably at least 60°, and still more preferably at least 80°. The angle is preferably no more than 150°, more preferably no more than 135°, still more preferably no more than 120°, and still more preferably no more than 100°.
In an alternative or additional refinement, the pile cutting apparatus 01 is preferably characterized in that the first cutting device 13 comprises at least one shielding element 86, which can be moved, in particular switched, for example pivoted, between at least one shielding position and at least one release position. The shielding element 86 is preferably at least partly arranged above the first table plane when the shielding element 86 is arranged in the shielding position thereof. The shielding element 86 is preferably completely arranged beneath the first table plane E when the shielding element 86 is arranged in the release position thereof. The shielding position of the shielding element 86 is used in particular to prevent scrap pieces 91, in particular individual parts of cut-off edge regions 92 of a cut sheet pile 92, from being hurled onto the second pile bearing surface 69, for example during the cutting operation. The at least one shielding element 86 is preferably rigidly arranged relative to the at least one support element 78 and/or is rigidly arranged with respect to the at least one bridge element 83. The at least one shielding element 86 is preferably likewise arranged pivotably about the switching axis 82. The release position of the shielding element 86 is used in particular to allow forward feeding of a sheet pile 26 onto the second pile bearing surface 69. For example, the at least one shielding element 86 has at least one ramp surface 88 and/or the at least one shielding element 86, at least in a release position, serves as a ramp element 86, in particular to facilitate forward feeding of a respective sheet pile 26 over the cutting gap 76. This specific release position of the shielding element 86 is then referred to as a ramp position. The ramp position of the shielding element 86, serving as a specific release position of the shielding element 86, is used in particular to ensure that a potentially drooping leading end of the sheet pile 26, during the forward feeding thereof in the direction of the second pile bearing surface 69, is brought back to the level of the first table plane E.
The at least one support element 78, at least in the support position thereof, and preferably always, is arranged between the first front pile bearing surface 04 and the first rear pile bearing surface 69, in particular along a transport path provided for sheet piles 26.
In an alternative or additional refinement, the pile cutting apparatus 01 is preferably characterized in that at least one switching device 89 is provided, which comprises the at least one support element 78 and the at least one bridge element 83. More preferably, the at least one switching device 89 also comprises the at least one shielding element 86. The at least one switching device 89 comprises, for example, a base body 91, relative to which the at least one support element 78 and the at least one bridge element 83, and more preferably also the at least one shielding element 86, are rigidly arranged and/or to which the at least one support element 78 and the at least one bridge element 83, and more preferably also the at least one shielding element 86, are attached. The at least one switching device 89, and in particular the base body 91 thereof, is preferably arranged pivotably about the switching axis 82.
For example, the switching device 89 can be switched between at least four or exactly four states. A first such state is an intake state. When the switching device 89 is arranged in the intake state, the support element 78 is preferably arranged in the intake position thereof. When the switching device 89 is arranged in the intake state, the bridge element 83 is preferably arranged in an interruption position. When the switching device 89 is arranged in the intake state, the shielding element 86 is preferably arranged in a shielding position. (
In an alternative or preferred refinement, the pile cutting apparatus 01 is preferably characterized in that a guide surface 87 for influencing a drop path of detached pile components or scrap pieces 91 is arranged beneath the upper blade 18. These can thus be conducted to a disposal device, for example a waste container or a transport means, after having slid off the contact surface 79 of the support device 78 following gravity.
In an alternative or additional refinement, the pile cutting apparatus 01 is preferably characterized in that the first pile cutting device 13 has at least one lowerable cutting aid 23 for pressing a part of a respective sheet pile 26 against the first front pile bearing surface 04 and/or that the first pile cutting device 13 comprises at least one lowerable hold-down device 52 for pressing a part of a respective sheet pile 26, in particular a part to be detached, against the first rear pile bearing surface 69. In particular, the first cutting device 13 is preferably characterized in that the first cutting device 13 comprises at least one first cutting aid 23, in particular a first press bar 23 for fixing sheet piles 26 and/or intermediate piles 28 and/or multiple-up piles 27, which is arranged so as to be at least movable with respect to a vertical direction V and which is arranged upstream from the first upper blade 18 along a transport path provided for a transport of sheet piles 26 and/or intermediate piles 28 and/or multiple-up piles 27. Preferably, maximum contact pressures between 0.5 N/mm2 (half a newton per square millimeter) and 2 N/mm2 (two newtons per square millimeter) are exerted by way of the first cutting aid 23. In this way, it can be ensured that, during cutting, no layers are displaced in relation to one another, and that a clean cut of all layers is carried out. For example, at least one first hold-down device 52 is arranged downstream from the first upper blade 18 along the provided transport path, which is in particular used to prevent cut-off components from being flung off in an uncontrolled manner.
In an alternative or additional refinement, the first cutting device 13 is preferably characterized in that the first cutting device 13 comprises at least one first cutting drive M1 for moving the first knife bar 16 in and/or counter to the first adjustment direction A1. The at least one first cutting drive M1 is designed, for example, as an electric motor M1 and/or as a linear motor M1 and/or as a pneumatic drive and/or as a hydraulic drive M1.
The preferably provided second cutting device 14 preferably comprises at least one second knife bar 17, at which a second cutting blade 19 is arranged, which is referred to as a second upper blade 19. The second upper blade 19 includes an in particular second upper cutting edge 22, which is preferably configured as a linear cutting edge 22. The second knife bar 17 is preferably arranged so as to be movable in and/or counter to a second adjustment direction A2 along a preferably linear, and more preferably exclusively linear, second adjustment path.
In an alternative or additional refinement, the second cutting device 14 is preferably characterized in that the second cutting device 14 comprises at least one second cutting aid 24, in particular a second press bar 24 for fixing sheet piles 26 and/or intermediate piles 28 and/or multiple-up piles 27, which is arranged so as to be at least movable with respect to the vertical direction V and which is arranged upstream from the second upper blade 19 along a transport path provided for a transport of sheet piles 26 and/or intermediate piles 28 and/or multiple-up piles 27. Preferably, maximum contact pressures between 0.5 N/mm2 (half a newton per square millimeter) and 2 N/mm2 (two newtons per square millimeter) are exerted by way of the second cutting aid 24. In this way, it can be ensured that, during cutting, no layers are displaced in relation to one another, and that a clean cut of all layers is carried out. For example, at least one second hold-down device 67 is arranged downstream from the second upper blade 19 along the provided transport path, which is in particular used to prevent cut-off components from being flung off in an uncontrolled manner.
In an alternative or additional refinement, the second cutting device 14 is preferably characterized in that the second cutting device 14 comprises at least one second cutting drive M2 for moving the second knife bar 17 in and/or counter to the second adjustment direction A2 and that the at least one second cutting drive M2 is configured as an electric motor M2 and/or as a linear motor M2 and/or as a pneumatic drive M2 and/or as a hydraulic drive M2.
In an alternative or additional refinement, the pile cutting apparatus 01 is preferably characterized in that the pile cutting apparatus 01 comprises at least one first pile positioning unit 02, in particular for positioning at least one respective sheet pile 26. A pivot axis assigned to this first pile positioning unit 02 is preferably oriented parallel to a vertical direction V. In an alternative or additional refinement, the pile cutting apparatus 01 and/or the respective cutting device 13; 14 are preferably characterized by comprising at least one sheet feed zone 43 and at least one multiple-up discharge zone 44 or securities discharge zone 44. The pile cutting apparatus 01 is used in particular to generate several multiple-up piles 27, in particular securities piles 27, from at least one respective sheet pile 26.
For example, the at least one first pile positioning unit 02 is preferably arranged immediately downstream in the sheet feed zone 43 or along a provided transport path. For example, the first cutting device 13 is arranged downstream from the first pile positioning unit 02. Preferably, the first pile positioning unit 02 is assigned to the first cutting device 13, in particular to be able to align respective sheet piles 26 in an optimized manner.
In an alternative or additional refinement, the pile cutting apparatus 01 is preferably characterized in that the at least one support element 78 is made of an elastic material, for example made of rubber. When in the support position, the support element 78 can then be arranged as close as possible to the lower blade 77 and, upon contact with the upper blade 18, be displaced thereby without any damage occurring. In this way, a critical area of the cutting gap 76 is decreased as effectively as possible.
