Problems solved by technology

Due to the frictional forces between the sheets that come into contact with the auxiliary stacking carrier, these sheets may be concomitantly withdrawn from the stacking area or creases that prevent further processing of the above-mentioned sheets

Embodiment Construction

[0019] A machine for processing sheets 7 , for example a die-cutter or a printing press 1 , has a feeder 2 and a receiver 6 . In the printing press 1 , the sheets 7 are removed from the sheet stack 8 of the feeder 2 and fed individually or in scales via the feed table 9 to the printing units 3 and 4 . These printing units 3 and 4 each contain a printing form cylinder 11 , 12 in a known manner. The plate cylinders 11 and 12 each have a device 13 , 14 for fixing a flexographic printing plate. In addition, each plate cylinder 11 , 12 is equipped with a device for semi-automatic or fully automatic changing of printing plates.

[0020] The sheet stack 8 rests on a main stacking plate 10 which can be raised in a controlled manner. The sheets 7 are removed from the top of the sheet stack 8 by means of a so-called suction head 18 which also has at least one suction gripper for separating the sheets 7 . In addition, a blower device for loosening the upper sheet and a detection eleme...

Abstract

A method and a device for combining an auxiliary stack and a main stack have a provision that a rake carrying the auxiliary stack is movable out of a stack area in an impact mode, then sheets contacting the rack are prevented from being entrained and the structure of the stack is preserved.

Description

technical field [0001] The invention relates to a method and a device for combining an auxiliary stack with a main stack in non-stop operation of a feeder of a sheet processing machine. Background technique [0002] In the case of combining an auxiliary stack temporarily held by an auxiliary stack carrier (for example a grid) with a main stack, the auxiliary stack carrier must be withdrawn from the stacking area again. Due to the frictional forces between the sheets that come into contact with the auxiliary stacking carrier, these sheets can be concomitantly pulled out of the stacking area or creases which prevent further processing of the above-mentioned sheets. [0003] DE 39 22 803 B4 shows two auxiliary stack carriers arranged opposite one another and configured as a grid, which can enter laterally into the stack area. When pulling out, the force acting on the sheets should be canceled so that the sheets remain unchanged in their position. [0004] DE 10 2010 053 587 A...
