Definitions

  • the invention relates to a device for forming an arc current of scales that partially overlap like scales Sheet processing machine, especially a printing press, in Working cycle of the sheet processing machine can be fed with a rotatably driven conveyor roller and a freely arranged above rotatably mounted cycle roll, between which arriving arriving Arch detectable and together with the arc stream already formed are eligible for further funding, whereby to push in an occasionally arriving one Bow under the already between the clock roller and conveyor roller located in the last arc of the arc stream, the cycle roll in the work cycle the sheet processing machine can be lifted off the conveyor roller and is driven drivable on the conveyor roller.
  • the object of the invention is therefore a device of the aforementioned Art to create, especially when promoting bow greater thickness ensures a safe, precisely fitting transport of the sheets.
  • This object is achieved in that the Time of the lifting movement and / or the lowering movement of the clock roller is variably adjustable during a work cycle.
  • the times of the lifting movement and / or the are preferably Lowering movement of the cycle roll during successive work cycles in particular manually adjustable.
  • the following Bow In order to apply the first arc to one another at different times to be able to compensate the arc current compared to the following arcs the time of the lowering movement of the cycle roll in the work cycle one of Conveyor roller and clock roller detected the first arc of an arc stream leading compared to the time of lowering the clock roll in the following the working cycle of the first sheet the following Bow can be adjustable.
  • control device can be controlled by a control unit which is preferably a manually adjustable adjusting device having.
  • the adjusting device is an adjusting device which moves the clock roller approximately vertically, this supports the exactness of the moment of lifting from the bow or placing on the bow.
  • the actuating device can be an actuating cylinder have, in which a pneumatically actuated piston can be moved is arranged, the piston rod on her from the actuating cylinder protruding free end carries the freely rotatable clock roller, preferably the piston pneumatically lowering the clock roller onto the conveyor roller is acted upon.
  • the actuator has an actuating cylinder in which a pneumatically actuated Piston is slidably arranged, the piston rod at her out the actuator protruding end attached to a stationary holder is and wherein the adjusting cylinder displaceable on the piston rod carries the freely rotatable clock wheel.
  • the actuator is on a parallel above the Conveyor roller extending crossbar arranged.
  • the device shown in the figures shows a sheet stack 1, of the top sheet by a suction head, not shown of the sheet stack 1 raised and with its leading edge in the conveying direction 2 over that which also inclines in the conveying direction 2 in the work cycle Bow flap 3 fed to a rotatably driven conveyor roller 4 becomes.
  • conveyor roller 4 is both an actuator 5 for lifting and Lowering a freely rotatable clock roller 6 as well as a double sheet sensing device 7 with a sensor roller that can be placed on the conveyor roller 4 8 arranged.
  • the actuating device 5 is on a parallel approximately above the conveyor roller 4 extending traverse 9 arranged while the double sheet sensing device 7 on a likewise approximately parallel above the conveyor roller 4 extending pivotally drivable pivot shaft 10 is arranged is.
  • the actuating device 5 has a holder 11 with which it is attached to the crossmember 9 is attached. On the holder 11 is an actuating cylinder 12 with his attached upper end.
  • a guide rod 30 with its upper is on the holder 11 End section guided vertically, with its lower end a roll holder 15 is attached.
  • the roller holder 15 is opposed to a guide rod 30 enclosing Compression spring 14 with one end on the holder 11 and the other End is supported on the roller holder 15 to the conveyor roller 4 spring loaded.
  • the roller holder 15 is attached, which has an axis 16, on which the clock roller 6 is freely rotatable.
  • the actuating cylinder 12 has an air connection at its lower end region 17 and at its upper end an air connection 28, of which via a solenoid valve 18, a vacuum line 19 and a vacuum line 29 lead to a vacuum source 20.
  • the solenoid valve 18 is from a control unit 21 between the vacuum source 20 with the air connection 17 or the air connection 28 connecting position adjustable.
  • the times of the lowering movement and the lifting movement of the clock roller 6 are on the control device by means of a manual setting device 22 21 adjustable so that the time of lowering the Clock roller 6 in the work cycle of the detected by conveyor roller 4 and 6 clock roller first arc of an arc current compared to the time of lowering the clock roller 6 in the following the working cycle of the first sheet Work cycles of the following sheets advance.
  • the path to be overcome by the actuating cylinder 12 is greater balanced for placement on the first arc of the arc stream, that the clock roller 4 at the same time in the work cycle of the first Sheet is placed on this as on the following sheets in their work cycles, in which the actuating cylinder 12 is shorter by an arc thickness Way to overcome.
  • the double sheet sensing device 7 has a pivot axis 24 pivotable pivot lever 23, at one free end of which Sensor roller 8 is freely rotatable and from its other free end a switch 25 can be actuated. Both the switch 25 and the Pivot axis 24 are arranged on a holder 26 which on the Swivel shaft 10 is attached.
  • the sensor roller 8 In the lowered position, the sensor roller 8 is at a distance which corresponds to the nominal arc flow thickness in the area of the conveyor roller 4. If one or more sheets are fed too much, this increases Arc current thickness and the sensor roller 8 is against the one Swing lever 23 pressurized compression spring 27 raised. In order to the other lever arm of the pivot lever 23 lifts from the switch 25 so that it triggers a signal, e.g. the funding company is interrupted.
  • the actuating device 5 on a crossbar 9 regardless of the Pivot shaft 10 of the double sheet sensing device 7 is arranged the lowering and lifting movements of the actuating device 5 can also regardless of the pivoting movements of the pivot shaft 10 and thus can be optimally adjusted in each case.
