Definitions

  • the invention relates to a device for stacking sheets, in particular scaly paper or cardboard sheets, in which the sheets are stacked on pallets which lie on a lifting and lowering storage platform.
  • a device of the generic type is known, with which a stack change can be carried out without interrupting the sheet feed and without sheet losses.
  • a stack is changed, intermediate stacking is carried out on an auxiliary stacking platform formed by a sheet metal, while the storage platform is lowered with full stacks, the stacks are unloaded and empty pallets are placed.
  • the auxiliary stacking platform is moved into the stacking area at the start of the stack change on the inlet side and below the sheet feed level. So that there are no displacements and / or compression of the sheets when entering the stack, two gaps are previously formed between the trailing edges of the sheet, into which clamping elements are moved, in order to clamp and hold the sheet packs located above the auxiliary stacking platform.
  • the separating element consists of several separating plates arranged at a distance from one another, the free ends of which are unwound to form separating fingers which are moved into the stack between the trailing edge of the sheet.
  • the gap between the trailing edges of the sheet is formed by moving the stack downwards relative to the separating fingers.
  • the invention has for its object to make a generic device simpler, so that fewer machine parts are required.
  • the invention enables the use of a bar grate that can be retracted into the stack with low friction as an auxiliary stacking platform that does not require any additional clamp elements for the retraction.
  • a bar grate 8 is mounted horizontally as an auxiliary stacking platform and can be moved into the stacking area, on which the sheets 1 are stacked, as shown in FIG. 5, while a finished stack 3 is being transported away.
  • the bar grate 8 consists of individual, spaced-apart bars that extend in the direction of sheet travel.
  • the rods have a diameter of approximately 30 mm and are arranged at a distance of approximately 60 mm from one another.
  • the vertical distance of the bar grate 8 from the feed plane of the sheets 1 is chosen so that the drop height of the sheets 1 is as small as possible and at the same time such a large number of sheets 1 can be stacked that sufficient time for the removal of the finished stack 3 and for Laying new pallets 4 is available.
  • a stop board 10 which can be shaken in and against the sheet running direction and side guide plates 11 are arranged at the level of the feed plane, which ensure a trouble-free and precise storage of the sheets 1 in a known manner.
  • the stop board 10 for the sheet leading edges is suspended in the frame 6, adjustable in the direction of sheet travel, and has cutouts through which the tips of the bars of the bar grate 8 can be moved.
  • the side guide plates 11 are adjustable in the frame 6 for adjustment to different format lengths and widths, both in the longitudinal and in the transverse direction.
  • a separating element is arranged in the free space between the end of the belt conveyor 2 formed by the outlet-side deflection roller 13 and the stacking area.
  • the separating element consists of a series of upwardly extending separating plates 14, which are fastened at a distance from one another on a machine-wide traverse 15 over the working width and whose ends angled to separating fingers 16 can be pivoted into the stacking area between the rear edges of the sheets 1.
  • the separating element 14, 16 can be raised from a waiting position below the bar grate 8 (FIG.
  • the separating element 14, 16 can be pivoted to a limited extent in the direction of the stack 3 and back, so that the separating fingers 16 can both be inserted between the trailing edges of the sheet in the stack 3 and can also be completely moved back out of the stack 3.
  • the separating plates 14 with the separating fingers 16 are arranged over the working width in each case in a gap to the bars of the bar grate 8, so that the bar grate 8 is moved independently of the separating element 14, 16 horizontally and the separating element 14, 16 independently of the bar grate 8 vertically in the required range can. Collisions are excluded from the design.
  • the length of the separating plates 14 measured in the vertical direction is greater than the vertical distance between the entry plane of the bar grate 8 and the feed plane of the sheets 1.
  • a floor conveyor 18 is used for the transport of empty pallets 4 and for the removal of pallets 4 with finished stacks 3, the conveying path of which covers the stacking area and additionally approximately the same area in front of and behind the stacking point.
  • FIG. 8 shows an enlarged view of details of the area between the inlet-side stands 12 at the level of the feed plane.
  • a rigid plate 19 Connected to the belt conveyor 2 is a rigid plate 19 which extends vertically downwards from the feed plane and which delimits the stacking area on the inlet side.
  • the plate 19 has through openings 20 for the bars 21 of the bar grate 8 and displaces further openings 22 to the through openings 20, in which the separating fingers 16 can be moved vertically from their waiting position into the feed plane.
  • the cutouts 22 are sufficiently wide since, in addition to the separating plates 14, feed channels for marking strip insertion devices can also be arranged in them.
  • the plate 19 widens against the direction of sheet travel. Its upper side 22 forms a guide surface for the sheets 1 in the feed plane. In the recesses in the upper side 22 there are lower ejection rollers 24 arranged, which, together with the upper ejection rollers 9 and blowing nozzles 25 blowing in the sheet running direction, ensure secure transport of the sheets 1 into the stacking area.
  • the blowing nozzles 25 are each arranged in the plate 19 next to the lower ejection rollers 24.
  • the fixed plate 19 forms with the side guide plates 11 and the bulletin board 10 above the bar grate 8 on all sides an exact guide for the sheets 1 and the intermediate stack.
  • This guide ensures that the sheets 1 are deposited precisely on the edge and, at the same time, prevents the intermediate stack from being displaced when the bar grate 8 is moved back when it is transferred to the empty pallet 4.
  • FIG. 1 shows the stacking device immediately before a stack change is initiated.
  • the sheets 1 transported in scale form by the conveyor belt 2 are placed on the stack 3, the upper side of which is kept at a constant height by correspondingly lowering the storage platform 5.
  • the notice board 10 shakes for a precise storage on the leading edge of the sheet.
  • the bar grate 8 is in its waiting position on the inlet side outside the stacking area.
  • the separating element 14, 16 is lowered into its waiting position, in which the separating fingers 16 are located at a distance below the bar grate 8.
  • On the infeed side in front of the stacking area a new empty pallet 4 is ready on the floor conveyor 18.
  • the machine Shortly before the predetermined number of sheets 1 is deposited on the stack 3, the machine is braked to a slower change speed.
  • the belt conveyor 2 continues to convey sheets 1 to the stacking point without interruption.
  • the separating element 14, 16 is raised into the region of the feed plane.
  • the separating fingers 16 pivot between the trailing sheet edges and lie on the stack 3. They separate the finished stack 3 from the following sheets 1 ( Figure 2).
  • the finished stack 3 is then lowered very quickly (at approximately 200 mm / s) to below the entry level of the bar grate 8, the separating element 14, 16 being moved downward by the stack 3. This is the pressure in the piston-cylinder unit 17 set so that the dead weight of the separating element 14, 16 is compensated.
  • the movement of the separating fingers 16 downwards is stopped by an adjustable mechanical stop immediately above the entry level of the bar grate 8. Since the stack 3 is lowered about 40 mm further, a gap is formed between the trailing edges of the arch, into which the bar grate 8 can move (FIG. 3). At the same time, the shaking of the notice board 10 is stopped.
  • the separating element 14, 16 is pivoted out of the stacking area and lowered into its waiting position (FIG. 4).
  • the storage platform 5 with the full stack 3 is lowered into the corridor area.
  • the full pallet 4 is transported away from the stacking area in the direction of sheet travel, at the same time a new empty pallet 4 is moved into the stacking area.
  • the bar grate 8 is stacked without interrupting the sheet feed (FIG. 5).
  • the new empty pallet is then raised from the storage platform 5 to below the bar grate 8 (FIG. 6).
  • the bar grate 8 By moving the bar grate 8 back out of the stack area, the partial stack formed on it is transferred to the pallet 4 (FIG. 7).
  • the elements lying exactly on the side surfaces of the intermediate stack (plate 19, side guide plates 11 and bulletin board 10) prevent the partial stack from being displaced during the transfer.
  • the change cycle has ended, the shaking of the notice board 10 is switched on again and the machine is accelerated again to its operating speed.
  • the bar grate 8 is mounted vertically stationary. In order to have enough time for the transport of the full pallets 4 and the transport of the empty pallets 4, the machine is slowed down when changing. This is necessary because the maximum drop height of the sheets 1 is limited to the stack 3 for trouble-free stacking.
  • the maximum drop height depending on the sensitivity of the paper or cardboard and the format, is approx. 300 mm for cardboard, for very sensitive paper it can be reduced to a maximum of 15 mm.
  • the maximum fall height corresponds to the maximum height of the Intermediate stacks during a stack change, i.e. the vertical distance between the feed level of the sheets 1 and the bar grate 8.
  • a connected computing and control unit calculates the required depending on the required changing time and the number of sheets that can be stacked Speed reduction and controls the machine accordingly.
  • the bar grate 8 is mounted so that it can move vertically over a certain distance by means of a lifting mechanism.
  • the bar grate 8 is lowered during the intermediate stacking in accordance with the increase in height of the intermediate stack formed on it, so that the problems with the maximum drop height described above do not occur.
  • a slowing down of the depositing speed is not necessary if the bar grate 8 can be lowered in accordance with the height of the intermediate stack formed on it during the transport of the pallets 4 to and from the pallet.
  • a vertically movable bar grate 8 is also advantageous if slow delivery and removal systems for the pallets 4 are present.
  • the invention has the further advantage that due to the few components between the inlet-side stands 12 there is space for marking devices which insert 1 marking strip into the stack 3 after a certain number of sheets.
  • the strip feed channels of the marking devices can be guided parallel to the separating plates 14 through the space between the bars of the bar grate 8 to the top of the stack and insert marking strips into the stack 3 there.
