Definitions

  • the invention relates to a method and a device for stacking sheet material, in particular paper sheets or paper sheet layers, which are fed to a stacking shaft in a sheet feed level and in a sheet inlet direction and collected in this stacking, and for removing a finished stack.
  • the EP 0 718 231 B1 describes a stacking device in which an auxiliary table is retracted in the sheet running direction for stack change, after a hinged from the same side separating finger has formed a gap for it.
  • the DE 31 22 451 C2 describes a stacking device in which an upper and lower auxiliary table are provided, which retract in the stacking direction and must therefore be arranged below the transport device for the sheet flow.
  • the upper auxiliary table engages like a finger in the arc current and creates a gap, in which the lower auxiliary table can be retracted.
  • the auxiliary table is provided with a rolling device, ie with bands that prevent relative movements and thus friction on the underside of the sub-stack forming thereon.
  • the DE 35 35 113 C2 also describes an insertable in sheet travel direction auxiliary table with a rolling device, wherein instead of a mechanical finger, the gap is kept open by means of blowing air.
  • EP-A-1 262 435 discloses a method for stacking sheet material having all the features of the preamble of claim 1 and an apparatus for stacking sheet material having all the features of the preamble of claim 10.
  • the devices that work with an auxiliary table have the problem that the stack of parts deposited on the main stack carrier must deform during depositing due to the thickness of the auxiliary table and thus is not exactly edge straight to the rest of the stack. This is especially to be feared for smooth and high quality papers.
  • the object of the invention is to provide a stacking method and a device in which a non-stop stack change without affecting the stack quality is possible.
  • the first auxiliary stack carrier enters in the course of an arc gap, which can be generated in any desired manner, preferably by means such as those in the DE 198 51 371 (corresponding EP 99 163 A and US 6,189,884 B1 ) is described.
  • This arc gap is sufficient to allow the first auxiliary stack carrier, preferably against the sheet inlet direction to retract.
  • the auxiliary stack is then formed on the entire stack shaft cross-over auxiliary stack carrier, which may preferably be designed as a plate. It is lowered according to the speed of stacking the sub-stack formed on it. During this time, the finished stack can be lowered completely and removed from the main stacker on which it rested. Initiated to transfer the auxiliary stack on the main stack.
  • the second auxiliary stack carrier moves, preferably in the direction of the sheet inlet and at the same height as the first auxiliary stack carrier into the slot, following the simultaneous retraction of the first auxiliary stack carrier.
  • Both auxiliary pile supports can be formed by free-circulating belts or other rolling measures, such as rollers or as an air table charged with blown air, so that there is no friction between them and the lower sheet of the auxiliary stack.
  • the bands can therefore be fixed on the stack facing upper support frame, ie immovable with respect to the stack, and in the horizontal movement of the auxiliary stack support each roll around the leading edge.
  • the second auxiliary stack carrier follows the withdrawal of the first, so that the auxiliary stack is supported evenly distributed over its entire surface and remains flat.
  • the second auxiliary stack carrier is reversed and returns behind the stack edge, preferably at the same rate as the first auxiliary stack carrier is further retracted.
  • the stack is freed from the middle of the auxiliary pile carriers and now rests on the raised in the meantime main stack carrier on which usually a transport pallet is placed.
  • the mid-region deflection of the stack resulting from retraction of the auxiliary pile supports is symmetrical, so that when both auxiliary pile supports are retracted, the stack rests flat and without edge offset in the forward or reverse direction on the main pile support.
  • Both auxiliary stack supports are formed with mutual toothing, ie formed from crenellated protruding and recessed elements that can engage with each other.
  • the leading edges of the protruding elements are chamfered, so that the deformation of the stack when placing on the main stack carrier is as harmonious as possible.
  • Gearing is still a flat surface formed from two auxiliary pile carriers when they are driven together.
  • the first auxiliary stack carrier is provided with longitudinally movable filling pieces which, during the formation of the auxiliary stack on this stack carrier, prevent the trailing edge of the sheets from bending downward in accordance with the chamfer of the front edge.
  • the patches are moved back again when the two auxiliary pile carrier interlock.
  • the lower edge of the first auxiliary stack carrier by means of optical monitoring, for. B. a photocell are detected while forms on the auxiliary stack.
  • the invention also has the advantage that the main stack can be formed directly on a transport pallet. It is also essential that due to the relatively high height that can reach the sub-stack before transferring to the main stack carrier, the main stack carrier does not have to be raised up in the range of Bogeneinvieris. Thus, it can stay below the range of stacking bay boundaries that are defined by so-called beaters, i. vibrating sheets are formed, which corrugate the bow. This allows the pallet to be placed on the main stack carrier so as to have a uniform edge over the stack edges, which is necessary for transport and storage purposes. It therefore needs no subsequent shift of the stack on the pallet more done.
  • the auxiliary stack formed is gripped at the front and rear edge by movable stops, in order to secure the lower edge of the stack against displacement in particular.
  • the side registration elements are in the stack because they are in vertical Direction the lowering auxiliary pile carriers can follow over a certain distance to prevent lateral displacement.
  • the second auxiliary stack carrier fulfills an advantageous function.
  • the finished stack lying on the main stack carrier, passes the starting position of the second auxiliary stack carrier, it is retracted into the stacking shaft. Then it can be lowered onto the finished stack while it moves down. He attacks him and can exert a contact pressure so that he holds the stack like a claw. This allows high lowering speeds without the risk that the upper leaves fly up and slip.
  • the second auxiliary stack carrier then moves up again and returns to its starting position to perform the previously described function in cooperation with the first auxiliary stack carrier.
  • Particularly preferred, however, is a method in which, after the retraction of the first auxiliary pile carrier, the main pile carrier moves upwards with the finished stack lying thereon, so that it rests on the underside of the auxiliary pile carrier under an adjustable contact pressure.
  • the main stack may, in order to allow this pressure to act for a while, synchronously, but while maintaining the contact pressure, ie pressure-controlled, follow the downward movement of the auxiliary pile carrier. Thereafter, the main pile carrier is driven down in rapid traverse to perform the removal from the stacking shaft.
  • the second auxiliary stacking table is preferably arranged under the sheet inlet region. It only needs to have half of the stacking bay width because it only has to reach the middle of the stacking shaft so that it and its drive are easier to accommodate. In addition, it can be located at a good distance below the sheet inlet position, so that even there the design freedom for the actual sheet inlet area is greater.
  • the first auxiliary stack carrier which covers the entire width of the shaft, preferably in the region of the stack leading edge forming shaft area, ie at the end of the machine, arranged where there is sufficient space for his work.
  • a paper processing machine can be provided with a stacker, which is designed as a non-stop stack changer.
  • a first auxiliary stacking table is retracted, on which an auxiliary stack can form.
  • this is moved synchronously with the re-extension of the first auxiliary stacking table to a middle position and extended out of this in opposite directions synchronously with the extension of the first auxiliary stacking table.
  • the partial stack formed on it then settles on a pallet lying on a main stacking table.
  • the synchronous symmetrical extension of the two auxiliary stacking tables stores the auxiliary stack without any edge offset.
  • Fig. 1 shows a collection station at the end of a paper processing machine, namely a cross cutter 11, in which sheets 12 are cut from paper webs wound in rolls.
  • the paper webs are, coming from several roles, cut longitudinally to several superimposed by rotating cutter shafts and cut from knife blades mounted knives across the sheet or superimposed sheet layers. If sheets are mentioned below, they also mean layers of several single sheets that are treated as a single unit.
  • a staggered or bowed sheet stream is generated from the sheets by deceleration and staggering, which are transported on a transport device 13 whose end is shown to a stacking device 14 substantially horizontally.
  • the transport device holds the shingled stream of electricity between upper and lower belt sections.
  • An upper belt 15 runs over a arranged in a machine frame 10 stacking shaft 16 of the stacking device away.
  • a device is provided with which a gap in the sheet flow can be generated for a stack change, without the processing machine 11 has to be completely stopped for it.
  • This device is not shown here and described in detail. It can be designed as in the aforementioned DE 198 51 371 A respectively. US Pat. No. 6,189,884 B1 the applicant. These are expressly referred to.

  • This is a vertically movable table, which depends on lifting chains 24 and by a drive 25 can be raised and lowered on guides 26 movable.
  • the main stack carrier 23 includes a conveyor belt 27, with with the pallet 22 and thus the stack 21 can be moved out of the stacking shaft to be transported there by a forklift or the like. The removal is also possible after the sides, ie perpendicular to the drawing plane.
  • a vertical drive 32, a horizontal drive 33 and a guide mechanism 60 for a first auxiliary stack carrier 28 are arranged on the machine frame 10 ( Fig. 1 ). As well as out FIG. 13 can be seen, it may be plate-shaped, but its the stacking shaft facing front edge 30 is divided into individual crenellated or comb-like tines or elements 29, between which corresponding recessed gaps 54 are formed.
  • FIGS. 1 . 10 and 11 show that the tines 29 have at their top a downwardly towards the free end 30 slope 55.
  • FIG. 13 FIG. 4 also shows that around each tine 29, and also in each gap 54, a flexible band 56 extends around the respective leading edge 30, so that almost the entire surface of the auxiliary pile carrier is covered with tape tabs which are each at the FIG. 13 not shown, right in the drawing, machine clamped while the lower run is stretched horizontally movable and can move at twice the speed of the horizontal auxiliary pile carrier movement. It is thereby achieved that during a horizontal movement of the auxiliary stack carrier its surface formed by the bands 56 fixed to the frame, that is, also remains immovable horizontally relative to the stack.
  • second auxiliary stack carrier 36 The same training, but with offset by half pitch tines 29, has a described in more detail below second auxiliary stack carrier 36. Its tines 29 interlock with those of the first auxiliary stack carrier 28 over a length, preferably twice Length of the slope 55 corresponds (see FIG. 11 ), so that a flat surface is formed when both auxiliary stacking carrier join the same level.
  • the first auxiliary stack carrier is provided in the region of the gaps 54 with horizontally displacing filling elements 57, which form the front edge 58 in the region of the gaps 54 and the same with the auxiliary stack carrier, ie not as this angschrägt at the front.
  • auxiliary pile carrier may slide around the respective leading edges or may be guided by rollers.
  • Such reducing the friction between the respective elements and the stack to be arranged thereon drain devices are known per se, for example from the DE 3535113 C2 , Auxiliary pile supports may instead or additionally be air tables coated with blown air.
  • the first auxiliary stack carrier is arranged horizontally and can be moved in the horizontal direction, so that it can be moved into the shaft in a first retraction direction (arrow 31) ( Fig. 2 ). He is also guided vertically movable together with its horizontal guide 60 and vertically movable by means of the drive 32. Its upper position is close to the bow entry level 17. Its usable length corresponds to the maximum stacking dimension in the sheet entry direction.
  • the already mentioned second auxiliary stack carrier 36 is arranged on the opposite side of the stacking shaft 16, namely below the transport device 13, the already mentioned second auxiliary stack carrier 36 is arranged. He is also in a horizontal direction and movable in the vertical direction, by a similar trained drive than that of the first auxiliary stacking table.
  • the in the FIGS. 1 to 3 shown upper position of the second auxiliary stack carrier 36 forms its initial position 40.
  • the auxiliary stack carrier is withdrawn from the shaft 16. It is considerably, for example, about 250 mm, below the sheet inlet level 17, ie below the side racket 19.
  • the second auxiliary stack carrier 36 is in its horizontal usable extent only about half as long as the usable shaft dimension in the sheet feed direction 20. In this direction is the second auxiliary stack carrier 36 by means of the horizontal drive 38 in the shaft retractable and height-displaceable by means of a vertical drive 37.
  • the stopper plate 18 is guided vertically movably by a stopper carriage 61 on a guide 62 and can be raised. At the lower end of a roller 63 is provided, which rest on the first auxiliary stack carrier 28 and thus can limit the Stopperwagen in the downward movement. A relative to the rest stopper plate 18 slidable nose 64 (similar to a door lock latch) ensures that no bends between the stopper plate and the auxiliary stack carrier 28 can pinch.
  • the side beaters 19 are guided movably in the vertical direction and can fall together with the auxiliary stack carriers, wherein they can rest on the surface thereof. However, this downward movement is limited to an area in which such clubs are necessary, including the upper portion of the stack.
  • FIGS. 10 to 12 especially FIG. 12 It is shown as a pivotable about an axis 65 and driven by the push rod 53 element and arranged so that it has a certain clearance angle during operation (see in particular FIGS. 10 and 11 ), that is, the next point to the stack, which is the actual Alignment takes place in the upper area. This ensures that when the stack is lowered, the lower parts of the plate forming the racket leave no marks on the stack trailing edge.
  • an alignment and guide element 66 is still provided, which between the in FIG. 12 shown upper position, in which shown in dotted lines lower position is movable. It is guided vertically in a guide 67 and also guided in the direction of the stack trailing edge 50 and away from it, so that it limits the stack trailing edge in the upper region and releases it in the lower region to avoid markings in the stacking reduction.
  • This element 66 rests on the second auxiliary stack carrier 36 under gravity and is carried along by it during the downward movement. It serves in the lower position to avoid a shift in the transfer of the auxiliary stack on the main stack carrier. When stack transfer the all-side guides of the stack can be approached to this. For the rest, the stack should be as free as possible.
  • Fig. 1 shows the stacking device in a position in which a stack 21 is completed and the last sheet 12 and the last sheet layer runs on him.
  • the stack 21 rests on the pallet 22 and this on the main stacking table 23.
  • the main stacking table 23 possibly clocked, depending on the speed of the stacking was moved down so that each sheet 12 in previously staggered or shingled, ie overlapping shape, accrue relatively smoothly on the previously filed bow and are knocked by the clubs 19, 51 to a straight-edged stack.
  • the upper edge of the stack is thus slightly below the sheet inlet level 17th
  • the transport device 13 is influenced so that a gap is formed in the stream of the incoming sheets 12. For a certain period, therefore, no bends arrive in the area of the stacking shaft. This can be achieved in different ways. Before that was the DE 198 51 371 A has been mentioned, which describes an advantageous way to do so. Possibly. In this case, the operating speed of the overall machine 11 can be reduced. However, it does not need to be stopped.
  • Fig. 2 shows that now the finished stack 21 is lowered by vertical downward movement of the main stack carrier 23 (arrow 41).
  • the stack upper edge 42 has passed the starting position of the first auxiliary table 28, this is retracted horizontally by means of its horizontal drive 33 in the stacking shaft, in the first insertion device 31, which is preferably the sheet inlet direction 20 opposite.
  • the illustrated first retraction has the advantage that even with a relatively early end of the gap, so an insertion of the arc current before total retraction, no lateral offset of the sheets is to be feared.
  • the first auxiliary stack carrier is lifted somewhat in the direction of the sheet inlet level 17 if necessary.
  • Fig. 3 shows that the first auxiliary stacking table 28 then covers the entire width of the slot at the level of the sheet feeding level and is ready for the sheets following the gap to be deposited on it.
  • the stack 21 by moving up of the main stack carrier 23 (arrow 68) is raised until it is briefly pressed against the underside of the auxiliary stack carrier 28. After that he moves for one certain time still in sync with the lowering of the auxiliary stack support 28 down.

  • the main stack carrier 23 is lowered at rapid traverse, eg at 155 mm per second.
  • the entire surface of the stack surface at the bottom of the auxiliary pile carrier, the air is squeezed out and stabilized the stack. An internal displacement of the stack in its further handling is thus largely excluded.
  • the device would also be possible to control the device so that after the stack top edge 42 has passed the starting position 40 of the second auxiliary stack carrier 36, this is retracted horizontally in overdrive in the stacking shaft 16 and then by lowering the top stack of the finished stack 21 with contact pressure is hung up.

  • Fig. 4 shows the position in which the finished stack 21 has reached its extended position and can now be moved out by starting the belt conveyor 27 from the main stack carrier 23. This can be done in the sheet feed direction 20 or also, with a corresponding orientation of the conveyor belt 27, laterally out of the device (perpendicular to the plane). It is also possible without a transport system However, this will increase changing times and require a forklift truck to be ready for use.

  • Fig. 5 shows that after unloading the stack 21 from the main stack carrier 23 by means of the conveyor 27, a new pallet 22 is placed on this.
  • this pallet normally has slightly larger dimensions than that of the stack, so that it has a lateral projection 46 (see FIG. Fig. 4 ) about the stack dimensions Has. This is important in order not to damage the stack edges and thus the sheet edges during the subsequent packaging, storage and transport of the stack.
  • the pallet can be positioned in the invention so that the supernatant 46 is present at all edges, because they, as will be apparent from the later executes, does not have to be raised to the area of the front or side rackets. In a direct collection of the stack on the pallet without forming an auxiliary stack, the stack would have to be moved later on the pallet, which in turn means risk of injury of the straight edge stack.
  • the main stack carrier 23 with the empty pallet 22 is now moved quickly upwards (arrow 47) until it moves to the position Fig. 6 has reached, directly below the starting position 40 of the second auxiliary stack carrier 36th

  • the auxiliary stack 45 on the auxiliary stack carrier 28 thus runs from above onto the already protruding section of the second auxiliary stack carrier 36 from above.
  • Fig. 6 Figure 12 also shows that after the auxiliary stack 45 has reached such a height that it has reached the same level as the second auxiliary stack carrier 36, ie its home position 40, in synchronism with the stack formation, the staple transfer of the auxiliary stack 45 has reached the pallet 22 and thus the main stack carrier 23 begins.
  • pallet fixing rails 70 are provided which bring the pallet in the exact position and also hold it during the transfer of the auxiliary stack on the pallet to prevent mutual displacement.
  • first and second auxiliary pile supports 28, 36 are moved synchronously (horizontally and vertically) so that the first auxiliary pile support 28 is moved out of the stacking shaft under the stack in the sheet insertion direction 20 while the second auxiliary pile support 36 immediately follows it, so that between them no gap, but the interlocking overlap (see also Fig. 11 ) preserved.
  • Both auxiliary stack supports 28, 36 thus push together under the stack along and over the pallet 22. However, they are not on the pallet with the lower run of the unwinding device, so that the two provided unwinding device (belts 56) is set in motion. The upper strand remains unmoved, so holds the bottom sheet of the stack that rests on him under the weight of the auxiliary stack 45. The belt unwinds counterclockwise so that the displacement occurs without friction between the lowermost sheet of the stack and its support. This avoids damage to this stack part.
  • Fig. 7 shows the position in which the two free ends 30, 39 of the first and second auxiliary stack supports, even more intertwined, have reached the middle area, preferably the exact center, of the stacking direction in the sheet entry direction.
  • the stack is now supported by both auxiliary pile carriers uniformly and substantially over the entire surface.
  • Fig. 8 shows that, starting from this middle position Fig. 7 , the second auxiliary stack carrier 36 is reversed and now extended again, and that opposite, but preferably at the same speed, as the first auxiliary stack carrier 28 continues to run in the sheet inlet direction.
  • the auxiliary stack 45 starting from the middle, can now deposit on the pallet 22, which requires a certain bending of the auxiliary stack 45.
  • the bevels 55 on both leading edges 30, 39 of the auxiliary stack carrier 28, 36 this bend is uniform and harmonious, and also exactly symmetrical, so that after the complete filing of the auxiliary stack on the pallet 22 and thus the main stack carrier 23, the stack is exactly straight again (see. Fig. 9 ). This also contributes to the fact that the auxiliary pile support need not be very thick due to their good leadership.
  • auxiliary stack 45 When placing the auxiliary stack 45 on the pallet 22 are vertically movable stops on Stopperwagen 61 (at the sheet leading edge) and in the area of the racket 51 (at the sheet trailing edge) initially with spring pressure or self-weight on the auxiliary stack carriers 28 and 36 respectively. These movable stops follow the stack bottom edge during the collection process and are designed to fall into the respective tooth space of the auxiliary stack carrier as they retract to their home position. This ensures that the movable stops already rest on the pallet 22 before the auxiliary stack 45 is completely deposited on the pallet. The lower edge of the stack can therefore be moved neither in the paper direction nor in the opposite direction.
  • the two auxiliary stack carriers were clocked together with the main stack carrier 23 according to the meanwhile continuing stacking or continuously lowered. It is also possible to boot up the main stack carrier 23 only to a position subsequent to the process phase Fig. 7 corresponds, ie the beginning of the partial stack storage.
  • Fig. 9 shows that now both auxiliary pile carrier extended and in their starting position after Fig. 1 and the stacking on the main stack 21 continues until it pending the change ( Fig. 1 ).
  • the invention provides numerous advantages in the method and apparatus.
  • the formation of the main stack takes place after the transfer directly on the later transport element (pallet).
  • the stack can be set in the middle in its later end position and formed on it. It therefore accounts for steel plates used in earlier stack quick exchangers as an intermediate carrier, by means of which the collected on pallets of paper stack had to be transported out of the stacking shaft and picked up by forklifts. These steel plates were then again loaded with empty pallets, transported into the stacking shaft, taken up by the stack quick coupler and placed in a provisional takeover position for stacking. Due to this system it was not possible to transport finished stacks without using tools like forklifts.
  • a structural advantage is the shortness of the second auxiliary stacking table, which is located at the critical point below the sheet transport system, and the fact that it can be located well below the sheet inlet plane.
