Definitions
- the invention relates to a device for the continuous separation of sheets a sheet stack from a stack magazine with one each to be separated Sheet in the area of its leading edge and from the sheet stack tilting suction element, with a gripper mechanism for taking over the tilted sheet from the sheet stack, with a stack magazine limit in Form of a front stop, if necessary with dividing tips, and with one under the front area of the sheet stack movable and this stack lifter supporting.
- the separating devices are each provided with a stack magazine, in which the sheets are stacked with alignment at a front boundary as well as on side guides.
- the bottom printed sheet is gripped by the sucker and with the back fold first through an opening Hand it over to the gripper mechanism of the take-off drum in the magazine bottom. It can be separating or at the front boundary of the stacking magazine Retention peaks can be provided, which are the separation of the printed sheet edge and Serve the entire stack of printed sheets.
- From DE-C-582 334 (D1) is a collating machine with known a straight-line trigger and deposit gripper, one of the sheets in a stack magazine by means of a Suction plate tilted the bottom bow in the area of his Front edge detected and fed to a collecting channel.
- the stacking magazine consists of a stacking plate to hold the stack of sheets as well as from a front stationary magazine stop. Furthermore, one is in timing with the movement the suction plate can be swiveled under the stack of sheets with an angle lever articulated on it to reach under and lifting the stack.
- the object of the invention is a device of the generic type To create a way that ensures a reliable separation of the sheets.
- a stack magazine there are printed sheets 1a on a magazine bottom 2 with their back folds in shape against a front magazine boundary a stop 3 and supporting the printing sheet edges on two in a defined distance from each other dividing tips 4 in the stop 3rd
- An additional support means forms a mobile under the sheet stack 1, the stack in the front area supporting stack lifter 70, which in time Coordination with suction cups 5 can be moved into a retracted position.
- the separating tips 4 in the stop 3 adjust so that they are more or less with a view to safe disconnection reach less far into the stacking magazine.
- the front stop 3 has a free space 3a the sheet following the tilted printed sheet 1a, the orientation in the magazine for this sheet from a contact surface 7a one from the stack lifter 70 formed stop part 7th is taken over, which is synchronized with the movement of the suction elements 5 into a space aligned with the front magazine boundary and the free space 3a blocking position and controllable back, so that the to separating sheets 1a for the process of capturing and tipping through the suction cup 5 is released from the contact surface 7a of the stack lifter 70.
- the invention is not limited to that shown and described Embodiment.
- the contact surface formed by the stack lifter 70 7a can be a separate one aligned with the front stop 3 Alignment element that can be moved back and forth or one on the front stop 3 hinged back and forth swiveling stop element use Find.
