Definitions

  • the invention relates to a method for accumulating sheets in stacks on one Stacking tray, with the steps: the sheets are placed on the stacking tray to be put down the stacking tray with the help of a one at a distance from the top sheet stack that has just accumulated over the stacking guide fed.
  • the invention further relates to a device for accumulating sheets Stacking on a stacking tray, with feeding means for feeding the sheets to the Stacking tray and for placing on the stacking tray, with one at a distance from the each top sheet of a stack that has just been collected above the stacking tray trending leadership.
  • Devices of the type described above are used in one or more side-by-side conveyor tracks consecutive sheets in stacks to accumulate.
  • sheets should also be used under sheets other flat articles such as film sections made of plastic, metal, nonwovens, paper or the like.
  • the sheets can be cut with a cross cutter or several strips separated and individually one after the other or in the form of a shingled stream are led to the stack.
  • the object of the present invention is to accumulate sheets in stacks to improve a stacking tray.
  • the advantages of the invention are in particular that even with high Feed speed of the sheets their particularly critical leading end due to the approximately constant distance between the guide and the one already accumulated stack at least in the area of the stacking tray in its freedom of movement remains limited. It can therefore stack even under difficult conditions homogeneous configuration can be obtained. Relative to processing in particular thin large-format sheet material is due to the constant low durability Distance from the leading end of the bow a constantly narrow margin Granted between the guide and the stack, so that a position-appropriate storage also difficult to handle sheet is achieved in the stack.
  • the advantages of the method according to the invention or Device according to the invention is particularly useful. Because even in this case can ensure that the distance is maintained even when changing the Stack storage remains constant. This can be achieved, for example, by means of actuators, the guide to the one already formed by changing the stacking tray temporarily dropping the stack on the stacking tray. It is also guaranteed that after changing the stacking tray if the Stack height the guide is also tracked this lifting to the distance to keep constant to the margin of the leading ends of the bow between Do not unduly restrict or disappear the guide and stack.
  • the aforementioned guidance is preferably part of the device according to the invention of the feed means and these can be upper conveyor belts for feeding the sheets to the Stacking tray or sheet deflector for deflecting those on the stacking tray include sheets to be deposited down towards the stacking tray, or a combination of both.
  • the sheets on the stacking tray are preferably in the area of Stacking tray braked. This can advantageously be done by the level of funding Bow substantially vertically penetrating front arranging means are effected.
  • These fronting means are preferably adjacent one end of the guide preferably adjacent to the ends of the above-mentioned upper conveyor belts or Arch deflector provided.
  • a Desired distance specified a current distance recorded, the current Distance compared with the desired one, if there is a discrepancy between the current deviation from the desired distance detects this deviation, and the current distance is adjusted to the desired distance if the deviation exceeds a predetermined tolerance value.
  • the device preferably has sensor means for determining the instantaneous distance, Control means for comparing the current distance with a predetermined one desired distance, and to activate the adjusting means to adjust the current distance to the desired distance.
  • the leadership i.e. the upper conveyor belts and / or the Sheet deflector and the sensor means arranged at a fixed distance from each other.
  • This distance corresponds to a desired distance between the guide and the top of a stack that has already accumulated, so is the desired one Distance always reached when the upper end of the sensor means already accumulated stack is detected.
  • the actuators need one If the position of the guide does not change. On the other hand, is such arranged sensor means no stack detected, the distance to the stack is too large so that the positioning means lower the guide towards the stack have to. On the other hand, if the sensor detects the closed side wall of the stack, then the distance is too small, so that the adjusting means guide away from the stack have to lift.
  • the sensor means advantageously have two on top of each other arranged light switches.
  • the sensor means is thus together with the above-mentioned fixed assignment of the sensor means to the Guide the correct distance between the guide and the top of the stack reached when the upper light sensor of the sensor means does not detect a stack and the lower light sensor of the sensor means detects the side wall of the stack. Because then the top of the stack is between the two light buttons.
  • the adjusting means preferably have an adjustment path which is sufficient to maintain the distance as desired even when the stack sinks or swells to the extent provided for the respective device.
  • the adjusting means have a hose, the diameter of which can be changed with fluid, preferably air, which also changes its length.
  • a threaded spindle or the like, which is driven by an electric motor, for example, can also be provided.
  • the adjusting means preferably act on a holding frame which serves as a holder for a belt deflection for the upper conveyor belts and / or the sheet deflectors.
  • Device 1 described is designed for a multi-use storage device and is in a correspondingly multiplied parallel arrangement within a common Frame 2 used, of which 2 side walls 4 are shown in the figure.
  • a common Frame 2 used of which 2 side walls 4 are shown in the figure.
  • Hoses 12 can be moved vertically in the direction shown by arrow 14.
  • the Upper ends 16 of the hoses 12 are connected to valves 20 via connections 18 connected.
  • the interior of the hoses 12 is hollow and can via the valves 20, which is connected to compressed air supply lines 24 via compressed air connections 22 Compressed air.
  • the lower ends 26 of the tubes 12 are airtight via end pieces 28 completed and at the same time firmly connected to the stage 10.
  • the tubes 12 When applied the tubes 12 with compressed air, the tubes 12 can be in the region of their centers 30 stretch in the manner of a muscle and can thus shorten their length L.
  • the compressed air is released again from the inside of the hoses 12 via the valves 20 so drained, the tubes 12 stretch again in the manner of a muscle to the length L, so as to return to the cylindrical shape shown in the figures to accept.
  • stage 10 there is a shaft 32 with sprockets 34 running in the guides 8 (see in particular Fig. 2) relative to the stage 10 stored fixed.
  • the shaft 32 provides that the stage 10 can be moved homogeneously.
  • end of the stage 10 carries this bracket 36, at the ends 38th Deflection rollers 40 for (not shown in FIG. 2) upper conveyor belts 42 for Feeding of paper sheets 44 (not shown in FIG. 2) are arranged.
  • the Upper conveyor belts also serve as guides for the paper sheets 44.
  • brackets 36 are also used as a guide for the bow Sheet deflector 46 arranged to deflect the upper conveyor belts 42 fed paper sheet 44 down towards a stacking tray 48.
  • Sheet of paper 44 is adjacent to the deflections 40 as a fronting device serving vertical wall 50 (not shown in FIG. 2) is provided.
  • hoses 12 which are, for example Festo hoses with the designation "Fluidicmuscle MAS-20-N-340-AA-MCHK-187610" can act in parallel to the process of the stage 10 according to arrow 14 also the deflections 40 connected to the stage 10 according to Move double arrow 52.
  • the upper conveyor belts 42 and the bow deflector 46 move.
  • the distance I between the undersides 54 of the sheet deflectors 46 and the upper one End 56 or sheet 44 of a stack 58 already on the stacking tray 48 accumulated paper sheet 44 is by tracking the sheet deflector 46th together with a corresponding front, i.e. adjacent to the wall Section of the upper conveyor belts 42 kept constant.
  • the undersides 54 are the bow deflectors 46 and the center 82 between the two light sensors 64a and 64b is thus fixed Spaced from each other. This fixed distance corresponds to a desired one Distance I between the underside 54 of the sheet deflector 46 and the upper end 56 of a stack that has already accumulated.
  • the light scanners 64a and 64b are over corresponding electrical connections 66 with a (in FIG. 2 due to the central, Control unit not shown by dashed lines shortening) 70 connected.
  • the control unit 70 can be, for example, a commercially available computer his.
  • the control unit 70 in turn is electrical (not shown in FIG. 2) Lines 72 connected to the valves 20.
  • the method according to the invention works as follows:
  • the upper end 56 of the Stack 58 decrease so much according to arrow 62 in FIG. 1 that the distance I between the underside 54 of the sheet deflector 46 and the upper end 56 of the Stack 58 becomes larger than a desired distance.
  • lies the plane of the top 56 at a distance I that is the desired distance corresponds exactly between the two light buttons 64a and 64b at height 82.
  • Das means that the lower light sensor 64a detects a side wall of the stack 58, while the upper light switch 64b no longer detects a side wall.
  • the upper end 56 further, so also the lower end Light scanner 64a no longer has a side wall of stack 58.
  • control unit 70 This is done over the lines 66 passed on to the control unit 70.
  • This information is provided by the Control unit 70 interpreted such that the distance I is too large, i.e. over the desired distance.
  • the control unit 70 therefore becomes the one according to the invention Activate actuating means in order to secure the sheet deflectors 46 attached to the holding bracket 36 long to lower until the light sensor also attached to the bracket 36 64a and 64b are again in a position in which the plane of the upper End 56 of the stack 58 again at the center 82 between the light buttons 64a and 64b.
  • the control unit 70 to the valves 20 given the command to release compressed air from the hoses 12, so that this expand in the direction of their basic length L and thus the distance I for so long decrease until the control unit 70 closes the valves 20 again.
  • both light sensors 64a and 64b detect the side wall of the Stack 58.
  • This situation is shown in Figure 1.
  • This information is about the line 66 passed on to the control unit 70.
  • the control unit interprets the signals of the light sensors 64a and 64b so that the distance I is less than that is the desired distance and thus the actuating means according to the invention are activated to increase the distance again, i.e. the bottom 54 of the To move the sheet deflector 46 in FIG. 1 upwards.
  • the control unit 70 is given the command to the valves 20 via the compressed air lines 24 and the connections 22 flow compressed air into the interior of the hoses 12 to let.
