Definitions

  • the invention relates to a sheet feeder for sheet-processing machines with a device for automatically aligning the side position of a stack, from which the sheets to be separated in each case can be detected by a transport device and fed to the sheet-processing machine, with an actuator on a stack that is movably mounted transversely to the sheet conveying direction bearing stacking table acts and receives the respective control signals from a sheet actual position detection device.
  • the sheet which is separated from a stack is generally fed to the machine via a feed table in order to be processed by the machine.
  • the machine is directly assigned a so-called side alignment device, which moves the sheet to a lateral mark in order to ensure an exact lateral alignment for its further processing.
  • the provided side alignment device compensates for a lateral offset of the individual sheets of a few millimeters.
  • a device has therefore become known in which the actual sheet position is determined immediately after the separation.
  • the conveying means along which the sheets are guided over the feed table, are then pivoted in accordance with the determined offset in relation to the normal conveying direction.
  • the bow held by suction cups leads there by an additional transverse movement directed perpendicular to this movement during its transport.
  • a device is also known in which the position of the individual paper sheets when they are in contact with the sheet-processing machine is detected prior to their side alignment, and in accordance with this position an actuating motor is actuated which drives the platform on which the sheet stack lies. adjusted transversely to the conveying direction.
  • the control circuit derived from this procedure is particularly subject to dead time, since a corrective movement of the sheet stack occurs only after about 6-8 sheets, depending on the scale flow length.
  • the actuating motor is activated for correction purposes by the individual photocell used with the associated light source through each individual incoming sheet, regardless of the actual position.
  • the present invention is therefore based on the object of creating a sheet feeder for sheet-processing machines in which the actual position can be determined and the individual sheets can be corrected without great design effort and using a quickly responding control mechanism , but still the transfer error of the V-ereinzelungs and transfer mechanism are detected.
  • the transfer errors in the sheet separation can be taken into account in an advantageous manner.
  • the evaluation result can also be influenced, for example by adjusting the distance.
  • the two reflective light barriers used are not only assigned to one side edge of the sheet, but each side edge of the sheet has a reflected light barrier, additional information regarding the sheet width is possible.
  • this actuating signal can be made dependent on a specific response time of the reflex light barrier in question.
  • the stack 2 which rests on a stacking table 3.
  • the sheet is separated from above via a pneumatically acting separating device 4, which separates the uppermost sheet 5 from the stack 2 and feeds it to the further transport mechanism.
  • the transport device that feeds the sheet 5 of the machine 6 or a cylinder 7 of the machine 6 is first formed by a feed table 8.
  • Endless conveyor belts 9 are arranged on this at certain intervals (see FIG. 2) by a deflecting roller. 10 are driven, two of these deflecting rollers 10, 11 extending over the entire width being provided in the sheet running direction before and after the feed table.
  • Another roller 12 also regulates the tension of the conveyor belts 9.
  • These are each assigned a plurality of transport rollers 13 on the feed table 8 and clock rollers 15 which are mounted to be displaceable longitudinally on a crossbar 14 by means of a support arm 26. These set according to the sheet processing processing speed of the machine 6 on the already isolated sheets 5 or lift off from it, which is caused by the crossbar 14 pivotable about its axis.
  • a further traverse 16 is provided, extending over the width of the sheet feeder 1 determined by the side parts 27.
  • optical detection devices embodied as reflective light barriers 19, 20 are fastened by means of brackets 17, which can be locked on the crossbar 16 by means of clamping screws 18.
  • the actuating signals for triggering the corrective movement of the stacking table 3 result from the different degrees of light reflection when it hits the white paper sheet 5 or "empty".
  • both reflex light barriers 19, 20 are assigned to a lateral sheet edge 21.
  • the sheets 5 are separated outside a certain tolerance range and assume the position shown in broken lines in FIG. 4, they are detected by both reflective light barriers 19, 20, which results in a specific actuating signal. This is transmitted to a servomotor 24, which laterally adjusts the stacking table 3 by a predetermined amount in the corresponding direction (to the right).
  • An actuating signal for the stack movement in the other direction is issued when, in an equivalent manner, the separated sheets 5 assume the position shown in dashed lines in FIG. 4 (both reflective light barriers 19, 20 go into "emptiness").
  • Another possibility would also be to assign a reflective light barrier 19, 20 to each of the two lateral sheet edges 21, 23. Additional information regarding the sheet width could be derived from this.
  • T a specific response time of the reflex light barrier 19, 20 concerned.
  • the number of sheets 5 from which the servomotor 24 carries out a corrective movement of the stack 2 can advantageously be predetermined.
  • the transfer errors in the sheet separation can be taken into account in an advantageous manner, so that finally the side drawing mark 25 has only a slight final alignment for the exact registration of the sheets 5.
