Problems solved by technology

As a result, waste sheets occur, which have to be removed from the machine in a time-consuming manner, wherein the individual sensors only detect protruding sheets that protrude to a large extent, while at the same time the skewed sheets themselves cannot be detected arrive

Embodiment Construction

[0060] exist figure 1 shows the output device of a sheet-fed processing machine, here in particular a sheet-fed printing press, in particular a sheet-fed offset rotary printing press, preferably constructed in a block and row configuration. Such machines are correspondingly operated with the lithographic method, wherein other printing methods, such as screen printing, can also be integrated in the machine. In the arrangement of the machine, the individual sheets 7 are gripped at the front edge by means of the gripper system of the rotating cylinders and handed over between the cylinders with the grippers locked. In the printing unit, the individual sheets 7 are each substantially inked with printing ink in the printing nip formed by the cylinder and the blanket cylinder. In addition, one or more varnishing devices are provided, in which the individual sheets 7 can be varnished by a varnishing forme cylinder. The cylinders arranged in the machine can be designed as single-siz...

Abstract

The invention relates to a machine for processing sheets with an output device and a delivery of the sheets to a stack of the output device and delivery of the respective sheet leading edge of the sheet onto at least two front edge stops sheet-fed feeding system of at least two front edge stops spread out the front edge stop plane, at least one further stop is provided for aligning the output device stack on the other edge of the output device stack , at least one detection unit is configured to monitor at least one point arranged behind the front edge stop plane in the direction of transport of the sheet, the machine for processing the sheet has a mechanism for feeding the sheet above the output device stack Sheet-fed feeding system, the present invention relates to a method for stacking sheets. At least one sensor is designed to monitor at least one further point, which is arranged in front of the front edge stop plane in the direction of sheet transport.

Description

technical field [0001] The invention relates to a machine for processing sheets with an output device and a sheet feeding system for feeding the sheets above the stack of the output device and to a method for stacking the sheets . Background technique [0002] In DE 10 2006 040 679 A1 a method and a device for stacking sheets of a sheet-fed machine on a sheet-sheet stack are described, wherein the sheets are fed by means of an endless sheet-fed feed The systems are transported one behind the other over the sheet stack and abut the leading edge of the sheet against a front edge stop. In order to enable precise stack formation, stop surfaces corresponding to such sheet-fed stacks in the upper region in the lateral direction are provided in this delivery device, with respect to the stop surfaces exhibiting a direction transverse to A reciprocating motion directed in the direction of sheet transport whereby the sheets are aligned with respect to their side edges. The position...
