Definitions

  • the invention relates to a device for depositing sheets, in particular sheets of paper, onto a stack in accordance with the preamble of claim 1.
  • a generic device for changing a sheet stack with uninterrupted conveyance of the sheets to the stacking point is known, with which a change of a full stack can be carried out without the rejection of sheets and without the risk of moving of sheets when changing stacks.
  • the device shown there has conveying means for the shingled feeding of sheets to a stacking point at which a lowerable storage platform is located.
  • On the back of the stack there is 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 that can be moved and lowered in the conveying direction of the sheets .
  • the vertically movable separating element is in the region of the top of the stack, in particular between the uppermost sheet of the stack and the stream of shingles, between the sheet rear edges insertable.
  • 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 extended or retracted.
  • the auxiliary stacking platform supports the top of the sheet stack while the bottom of the stack is removed.
  • the device shown in DE-OS 36 16 470 is designed for the production of relatively large stacks on pallets. For huge storage of sheets, in the stack of low height with z. B. 500 or 1000 sheets are made, the device is less suitable because the minimum distance of the lower jaw from the feed plane, which determines the smallest stack size that can be generated, must be kept relatively large for design reasons.
  • the invention has for its object to provide a generic device with which sheets can be deposited without loss to stacks of low height at high feed speed.
  • the device according to the invention has at least three clamp elements, which are inserted one after the other cyclically in the stack that is being formed. Between two clamp elements there is a number of sheets corresponding to the ream size, which can be transported separately one after the other without having to interrupt the sheet feed.
  • the individual clamp elements each take over the function of the upper and lower jaws in accordance with DE-OS 36 16 470 in the stack and are raised again after being moved out of the stack in the lowest position by a separate lifting device and retracted into the stack.
  • the depositing device shown in FIG. 1 is used for depositing sheets of paper, which are conveyed from conveyor belts 1 and produced by an upstream cross cutter, onto a stack 2.
  • Their frame has four stands 3, 4, in which a depositing platform 5 by means of a screw jack 6 from the feed plane the sheets can be moved vertically up to a transversely conveying belt conveyor 7.
  • the storage platform 5 consists of a circumferential cloth, which is driven by a motor 8, to the stacked giant the cross conveyor 7 handed over, which transports them to a subsequent packaging facility.
  • a carriage 9 is arranged below the feed level in front of the stands 3 and carries an auxiliary stacking platform 10 which can be moved horizontally into and out of the stacking area.
  • the carriage 9 can be moved vertically with the platform 10 by means of a spindle jack 12, the downward movement being able to be synchronized with the downward movement of the storage platform 5 by coupling with the spindle lifting mechanism 6.
  • the device has the known deposit elements: a notice board 13, upper belts 14 and side shaking plates 15.
  • the belt conveyor 1 consists of individual belts which are arranged next to one another at a distance and are deflected by rollers 16, 17.
  • the outlet-side rollers 17 have a width corresponding to the belt width and are arranged directly in front of the area of the stack 2.
  • the shingled sheets 18 are deposited on the stack 2 in a known manner.
  • three bars 19.1 - 19.3 extending across the working width are arranged (Fig.
  • each bar 19 has a projection 21, 22 on both sides outside the working width, on which movable clamp elements, which are shown in more detail in FIG. 4, engage with the clamps 20 along the closed curve ABCDE for moving the bar 19 .
  • the two projections 21, 22 of a bar 19 are horizontally offset against the projections 21, 22 of the other bars 19.
  • pneumatic piston-cylinder units 23.1-23.3, 24.1-24.3 are arranged on both lateral front stands 3, each of which vertically move a pneumatically actuated clamping element 25.1-25.3, 26.1-26.3.
  • the clamping elements 25 arranged on the outlet side next to the trailing edge of the stack are exclusively vertical, and the clamping elements 26 arranged in front of them in the direction of sheet travel can also be moved vertically and horizontally up to the vicinity of the trailing edge of the stack by means of pneumatic piston-cylinder units 27.1-27.3.
  • This construction makes it possible to move the three beams 19 with clamp elements 20 on a closed path to the positions AE (FIG.
  • a spindle hoist 28.1-28.3 is arranged above each outlet-side piston-cylinder unit 23, the spindle of which presses on the projections 22 from above onto the bars 19 against the force of the piston-cylinder units 23.
  • the screw jacks 28 are controlled by a control device, not shown, so that the bars 19 move vertically from A to B - while the brackets 20 are in the Stack 2 is located - move downwards in synchronization with the storage platform 5 or the auxiliary stack platform 10.
  • FIGS. 6-11 The mode of operation of the device is shown in FIGS. 6-11:
  • the depositing platform 5 is moved downward in order to keep the drop height of the scaly-fed sheets 18 constant when leaving the belt conveyor 1.
  • the first clamp element 20.1 moves between the uppermost sheet of the stack 2 and the scale flow into the stack area (FIG. 6).
  • the clamp element 20.1 is simultaneously moved upward in order to form a gap between the trailing edges of the arch by lifting the arch 18 and thus to avoid bumping against the trailing edge of the arch.
  • the clamp elements 20.2 and 20.3 are in the middle and lower waiting position (D and C) at a distance from the rear edge of the stack. With the downward movement of the storage platform 5, the associated screw jack 28.1 presses the clamp element 20.1 downwards in synchronism.
  • the element 20.1 is taken over by the clamping element 26.1 and horizontally by means of the piston-cylinder unit 27.1 from the stack first to the lower waiting position C and then by means of the piston-cylinder unit 24.1 to the upper waiting position E moves.
  • the waiting position E is free since the stack above the element 20.2 has now reached a large size and the clip element 20.3 has been moved into the stack 2.
  • element 20.3 clamps a ream (Fig. 10).
  • the storage platform 5 is then lowered again in an accelerated manner and the auxiliary stacking platform 10 moves into the gap formed below the element 20.2.
