  • From DE-OS 36 16 470 is a method for changing a sheet stack with uninterrupted conveyance of the sheets to the stacking point, with which a change of a full stack can be carried out without the rejection of sheets and without the risk of moving sheets exists when changing the stack, and a device for performing the method is known.
  • the generic device shown there has conveying means for the shingled feeding of sheets to a stacking point at which a lowerable storage platform is located.
  • a vertically movable separating element consisting of a swivel arm and a dividing plate arranged at the free end, two vertically offset clamping jaws that can be moved vertically and in the conveying direction, and an auxiliary stacking platform, which can be moved and lowered in the conveying direction of the sheets, are arranged on the rear of the stack .
  • the vertically movable separating element is in the area of The top of the stack, in particular between the uppermost sheet of the stack and the shingled stream, can be inserted between the sheet trailing edges.
  • the separating element and the clamping jaws are fork-like or rust-like and laterally offset from one another, so that the clamping jaws can reach through the separating element.
  • the clamping jaws move into gaps created by the separating element between the trailing edges of the sheets and clamp a sheet pack while the auxiliary stacking platform is being moved in or out.
  • the auxiliary stacking platform supports the top of the sheet stack while the bottom of the stack is removed.
  • the invention has for its object to provide a generic device that is able to perform the necessary vertical movements of the stack change the individual stack change elements with little design effort with the required accuracy.
  • Claims 2 to 4 contain preferred, since particularly advantageous, embodiments of the invention.
  • the screw jack according to claim 2 ensures, in addition to the exact height control of the storage platform, great security against a crash of the storage platform.
  • the gimbal according to claim 3 prevents the spindle nuts from jamming on the spindles, e.g. as a result of a deflection of the storage platform under the load of the stack. In the device according to claim 4, it is not necessary to clamp the sheet packs to lift the sheet edges against their own weight.
  • Claims 5 to 8 contain advantageous embodiments of the invention, in which a trouble-free retraction of the separating element between the trailing edge of the sheet is ensured.
  • the coating of the clamping pliers according to claim 9 avoids markings on the sheets on sensitive papers that can occur on metal surfaces.
  • the frame of the stacking device has four stands 1.1, 1.2, between which there is a storage platform 2 provided with transport chains rotating in the conveying direction. With the circulating transport chains, the full pallets 3 can be conveyed from the stacking area with the paper sheet stacks.
  • the storage platform 2 can be raised and lowered between the stands 1 by means of a screw jack.
  • the spindle hoist consists of four vertical spindles 4 arranged in the stands 1 with a common drive 5, on the spindle nuts 6 of which the storage platform 2 is fastened.
  • the storage platform 2 is attached to the spindle nuts 6 via a cardanic suspension, which is shown in more detail in FIGS. 4 and 5:
  • An annular element 8 is rotatably suspended from the spindle 7 on each spindle nut 6 by means of two horizontal pins 7, which are fastened coaxially on opposite sides parallel to one side of the storage platform 2.
  • two horizontal opposite pins 9 are fastened coaxially and perpendicular to the pins 7.
  • a protruding part 10 of a corner of the storage platform 2 is rotatably mounted on the pin 9.
  • a safety nut 11 arranged below the spindle nut 6 is connected to the latter via a switching pin 12, which actuates a limit switch 13 for an emergency stop when the axial distance between the two nuts 6, 11 is reduced.
  • the cardanic suspension of the storage platform 2 prevents the spindle nuts 6 from tipping over and thus prevents them from jamming on the spindles 4.
  • a pallet 3 can be raised into the area of the feed conveyor for the shingled sheet stream 14, which is designed in a known manner as a belt conveyor which is fixed in height.
  • the known elements 15 for the exact placement of a sheet on the stack 16.
  • a rear stop 15.1, side guide plates 15.2, vibrating plates etc. These elements 15 are horizontal, transverse to the conveying direction, for adaptation to different sheet formats movable, but fixed in height.
  • a further vertical spindle 17 is arranged in front of the spindles 4 of the storage platform in the direction of the sheet travel.
  • These two spindles 17 carry a carriage 18 extending across the working width, in which - from top to bottom - the upper jaw 19, the lower jaw 20 and an auxiliary platform 21 are each movably mounted in the conveying direction, so that they can be moved independently of one another in the Area of the storage platform 2 and back can be moved.
  • these can be coupled to a separate drive 23 by means of a coupling 22. It is also possible to uncouple them from the drive 23 and to couple them to the drive 5 of the spindles 4 of the storage platform 2 in order to achieve a synchronous vertical movement of the carriage 18 and the storage platform 2.
  • the auxiliary stacking platform 21 consists of a trolley of low height which is rotated in the conveying direction by a low-friction cloth 24 and can be moved horizontally by means of a travel drive 25. Its dimensions correspond to the maximum archable format.
  • a separating element 27 which can be raised with two vertical lateral pneumatic cylinders 26, is arranged.
  • the separating element 27 has separating plates 27.2 fastened next to one another on a swiveling traverse 27.1 over the working width and which can be swiveled into the stacking area with their ends angled to separating fingers between the trailing edges of the sheets.
  • the separating elements 27 can be raised to the area of the feed conveyor and lowered to below the auxiliary stacking platform 21. Their structure is shown in detail in FIGS.
  • a side part 27.3 which can be moved vertically by means of the pneumatic cylinders 26 is mounted on each of the upright stands 1.1.
  • the two side parts 27.3 are connected to a crossbar 27.4 and a synchronous shaft 27.5 with gearwheels 27.6 attached to the ends.
  • the gears 27.6 mesh in racks 27.7 on the stands 1.1, so an exactly synchronous vertical adjustment of the two side parts 27.3 is guaranteed.
  • the swivel cross member 27.1 which extends across the working width, is articulated by means of an irregular double swing construction.
  • Each double rocker consists of a coupling member 27.8, to which the swivel cross member 27.1 is rigidly attached, and which is articulated to the respective side part 27.3 via two unequal-length links 27.9, 27.10.
  • the joint of the shorter link 27.9 is located on the side part 27.3 vertically above the joint of the longer link 27.10.
  • a pneumatic swivel cylinder 27.11 which is supported on the respective side part 27.3, engages on the longer handlebar 27.10.
  • the separating plates 27.2 are releasably clamped on the swivel cross member 27.1 at a distance from one another. Clamping takes place by means of an additional sheet 27.12 riveted at an acute angle to the rear of each separating sheet 27.2, at the end of which a magnet 27.13 is attached, which attracts the divider 27.2 and thus clamps the swivel traverse 27.1 between the divider 27.2 and the additional plate 27.12.
  • the two clamping jaws 19, 20 are made up of horizontal pliers 19.1, 20.1, which are fastened next to one another and are coated with low friction.
  • Pneumatic cylinders 28 can be used to move both clamping jaws 19, 20 independently of one another about 10 cm horizontally into and out of the stacking area.
  • the coating consists of felt or a felt-like material and covers the entire surface of the pliers 19.1, 20.1. as far as they can be moved into the stack 16. It is glued to the pliers 19.1, 20.1.
  • the pliers 19.1, 20.1 are arranged offset with respect to the separating plates 27.2 of the separating element 27 in order to avoid mutual interference during opening and closing.
  • the upper jaw 19 can be additionally moved vertically by means of a double-acting pneumatic cylinder 29 in order to clamp a sheet pack located between the jaws 19, 20 to the trailing edge of the sheet .
  • the carriage 18 is in its vertical waiting position below the feeder for the shingled stream 14.
  • the two clamping jaws 19, 20 and the Auxiliary stacking platform 21 have moved back outside the stacking area.
  • the upper jaw 19 is pressed by the cylinder 29 upwards against a stop on the stand 1.1.
  • the separating element 27 is in the waiting position below the auxiliary stacking platform 21.
  • the stack height measuring device controls the downward movement of the depositing platform 2.
  • the separating element 27 moves up and the angled part of the separating plates 27.2 pivots between the uppermost sheet of the stack 16 and the shingled stream 14 between the sheet trailing edges.
  • the separating plates 27.2 abut against a sheet rear edge when swiveling in. This is achieved by the simultaneous upward movement of the separating plates 27.2 when swiveling in.
  • the angled part of the separating plates 27.2 is raised in front of the stacking area up to the top sheet on the stack 16, at the same time it lifts the sheet that has just been fed. In this way, a small gap is formed between the two sheets, so that the angled part of the separating plates 27.2 can easily rest on the stack 16.
  • the separating element 27 is then moved downward with the stack 16. It is stopped at the level of the lower jaw 20 and thus forms a gap between the trailing edges of the sheets into which the lower jaw 20 moves about 10 cm.
  • the spindles 17 carrying the carriage 18 are coupled to the drive 5 of the storage platform 2, so that from this moment on the carriage 18 moves downwards in synchronism with the storage platform 2.
  • the upper jaw 19 does not follow the downward movement because it is held in its vertical position by the cylinder 29 pressed against the stop.
  • the separating element 27 is moved out of the stack 15 and moves up again and between the trailing edge of the sheet to form a second gap. Since the storage platform 2 has moved further downwards, there is a vertical distance of approximately 250 mm between the two gaps.
  • the separating element 27 is removed from the The stack is pulled out and the sheet pack is clamped between the two jaws 19, 20 by moving the upper jaw 19 downward.
  • the carriage spindles 17 are uncoupled from the drive 5 of the storage platform 2 and coupled to their own vertical drive 23.
  • the slide drive 23 is regulated by the height measuring device on the top of the stack from this point in time.
  • the drive 5 of the storage platform 2 is accelerated in order to widen the gap between the lower clamping jaw 20 and the lower stack part.
  • the auxiliary stacking platform 21 enters this expanded gap and supports the upper stacking part.
  • the lower part of the stack is now accelerated downwards and transported away.
  • the exemplary embodiment described above is designed for stacking relatively large-format sheets of paper with edge lengths of approximately 500 mm - approximately 2000 mm, wherein stacks up to a height of 2000 mm are produced. It can also be used as a huge deposit, with a desired number (e.g. 500 or 1000 pieces) of smaller-sized sheets being combined into stacks and then packed.
