  • the object is achieved according to the invention solved a method, which is characterized in that the plate cylinder Push the pressure plate backwards so far towards the removal position pushes and the removal position to the plate cylinder in such a position and Alignment is that the front edge of the plate is when opening the Leading edge tensioning device and a forward rotation of the plate cylinder of removed and moved to the removal position.
  • the device for performing the method provides that the pull-out shaft Holding means having a backward movement of the pressure plate against the Prevent sliding direction, and that the controller is designed such that it Reverse rotation of the plate cylinder continues until the opening of the Leading edge tensioning device and a forward rotation of the plate cylinder as well due to the location and arrangement of the pull-out shaft in the direction of The plate cylinder has the end of the pull-out shaft on the front edge of the printing plate that end.
  • the methods and devices according to the invention have the advantage that they do not need additional resources to feed and remove the printing plates capture and transport. This function is fully taken over by the Plate cylinder.
  • the plate cylinder detects them in the Deployment position by the leading edge tensioning device by a Reverse rotation of the plate cylinder grips the front edge of the pressure plate.
  • the plate cylinder pushes the printing plate in the removal position and finally gives the leading edge of the printing plate freely that there is a brief moment at the backward rotation for unwinding the printing plate Forward rotation connects through which the leading edge tensioning device Front edge of the pressure plate releases and this is due to its internal stress and / or deposits its weight in the removal position.
  • An embodiment of the device for the automatic feeding of printing plates provides that the feed chute is in its feed position with its lower one End in a tangential plane to the circle of movement of the leading edge tensioning device is located, which extends obliquely upwards from the clamping area. This is it is possible to insert a new pressure plate into the top of the feed slot and it using their gravity to their end position for feeding to Let the plate cylinder slide into the feed slot.

  • This holding means creates a counterforce generated so that the pressure plate when inserted into the The position of the leading edge tensioning device has not been changed.
  • Can be used as a holding device at least one, but preferably two spaced-apart suction cups are provided be retractable from the insertion path for the pressure plate and for holding the Pressure plate can be moved into the feed shaft. With such suction cups the pressure plate is positioned securely.
  • clamping levers as holding means, since they do not require a drive, but clamp automatically if due to the insertion process in the Front edge tensioning device counteracts a slight movement of the pressure plate the direction of insertion.
  • the feed chute has positioning means for the printing plates.
  • the positioning means are advantageously two positioning pins, which is intended for engagement in two spaced-apart recesses of a pressure plate are.
  • Most printing plates have such recesses, since this is the Precise registration in the front edge clamping device of the plate cylinder serve, which also has such positioning pins for this purpose. To the It is planned to release the printing plate in the feeder shaft after this positioning. that the positioning pins can be moved away from their engaged position.
  • the interaction of the movable positioning pins with is particularly advantageous Holding means: First the pressure plate is inserted using the positioning pins precisely aligned, then held by the holding means and then the positioning pins moved away. As a result, the pressure plate is in an exact position in which it is from the leading edge tensioning device with insertion of the recesses of the pressure plate included in the register bolts of the leading edge tensioning device and can be clamped in register.
  • the device is advantageously designed in such a way that the feed shaft of the retracted position is movable into a rest position. Such a shipment in the rest position should take place because the intake shaft with its lower End must be very close to the plate cylinder and in the Reaches into the printing unit.
  • the Feed slot is removed from the plate cylinder and positioned in front of the printing unit. This is achieved, for example, in that the feed chute consists of a essentially vertical upper area and a lower area, which for Insertion of the pressure plate from the substantially vertical position to Plate cylinder is pivotable. This swiveling movement causes the lower part of the feed slot in the position in which the pressure plate for the Detection is kept ready by the leading edge clamping device.
  • this lower part of the feeder shaft can be removed from the Printing unit can be swung out. In this position it is also easier to create a new one Push the pressure plate into the feed slot because the pressure plate is straight can be pushed in.
  • the pivoting of the lower part of the Feed slot also has the advantage that the upper area is always parallel to Printing unit runs and therefore never in the aisle between the printing units protrudes.
  • the feed slot at its lower limit over its entire width distributed rollers for guiding the printing plates. From the same reason it is proposed that the feed shaft to guide the Pressure plate with beads, which are coated with lubricants, which is extend along the path of the pressure plates.

  • This arrangement has the Advantage that the pull-out shaft runs essentially parallel to the feed shaft and thereby a compact device for feeding and removing Printing plates is possible.
  • Another advantage is that after opening the Leading edge clamping device and the release of the pressure plate leading edge by the Counter-movement of the plate cylinder is not only due to the pressure plate Elasticity but also by gravity on the collecting plate. Thereby is guaranteed to move away from the plate cylinder while doing so Takes up position.

It will malfunction avoided if the trailing edge tensioning device is the trailing edge of the pressure plate does not release what, for example, by changing their voltage due to a manual intervention can occur.
  • a sensor in the upper area of the pull-out shaft is arranged, which detects whether a printing plate the predetermined removal position has reached.
  • This sensor can either serve that the signal for Interruption of the process and to the controller for error indication, or it can serve to remove a printing plate from the plate cylinder prevent as long as there is still a pressure plate in the pull-out shaft.
  • the latter function is intended so that the sensor before each change from the Control is queried whether there is still a pressure plate in the pull-out shaft and only after removing the device for a printing plate removal from Plate cylinder is released.
  • This changing system is expediently designed such that the Feed slot and the pull-out shaft have upper and lower areas, wherein the latter are pivotable together and by at least one 3-position cylinder in a feed position, a pull-out position and a rest position are spendable.
