Embodiment Construction

[0046] exist figure 1 The output device of a machine for processing sheets (here in particular a sheet-fed rotary printing press) is shown in . Here, the machine can in particular be operated according to the lithographic method. The last printing cylinder 1 is shown in a sheet-fed rotary printing press. A drive sprocket 2 and a deflection sprocket 3 are shown in the sheet output device. The sprockets 2 and 3 are each connected to a shaft 4 , 5 on which a further drive sprocket 2 or deflection sprocket 3 is arranged at a distance. An endless chain 6 forming a chain loop is guided by means of sprockets 2 , 3 . Between the two sprocket rings, gripper carriages 8 holding the individual sheets 7 are arranged at a constant distance from one another. The sprockets 2, 3 and the revolving chain 6 together with the handle trolley 8 form a sheet-fed feeding system, which can also be composed of other elements. In particular, the steering of the handle trolley 8 can also be carried ...

Abstract

The invention relates to a delivery unit of a sheet-processing machine having a sheet-conveying system that transports sheets to a delivery stack and having a sheet front edge of the sheets at at least two front edge stops. The invention further relates to a method for operating a sheet-processing machine, in which at least one detection unit is provided, which monitors the position of the sheets in a contactless manner, and in which the at least one detection unit is designed to monitor at least one point that is downstream in the sheet transport direction of a stop plane spanned by the at least two front edge stops. The problem addressed by the invention is that of creating a delivery unit of a sheet-processing machine. In particular, the delivery unit is designed in such a manner that damage caused by entrained sheets can be reliably excluded and the efficiency of the machine is increased. According to the invention, the problem is solved in that the at least one monitored point (P) lies within a region (B) that extends 100 mm in the sheet transport direction (15), starting from the stop plane (e).

Description

technical field [0001] The invention relates to an output device of a machine for processing sheets, having a sheet that is fed to an output device stack and whose leading edge of the sheet is fed to at least two leading edge stops A paper feed system, and to a method for operating a machine that handles individual sheets of paper. Background technique [0002] In DE 10 2006 040 679 A1 a method and a device for placing sheets of a machine for processing sheets on a sheet stack are described, wherein the sheets are fed one behind the other by means of a revolving sheet feed system Transported above the sheet stack and with the leading edge of the sheet against the leading edge stop. In order to be able to achieve precise stacking, in this delivery device there is provided a stop surface for the sheet-fed stack that is arranged laterally in the upper region, the stop surface is designed transversely to the direction of sheet-fed transport ground-directed reciprocating motion...
