Collating machine with error-indicating rejection device

摘要

The invention relates to a collating machine with several successively arranged feeders for the conveyance of sheets of paper on a conveyor line and with control devices at each feed station to monitor the formation of book blocks from which machine cycle-dependent error signals are output in the event of missed or duplicate feeding. It is the object of the invention to alter the operational flow of a conveyor line in such a way that in the event of defective book blocks, a manual separation of the book blocks and sorting of the individual sheets or sheet layers into the magazines at the feed stations can be eliminated. According to the invention, this is achieved by using a micro-computer to control a sliding rejection device with a station number indicator, located at the end of the conveyor line for the book blocks. The defective, separated book blocks are completed or corrected by an operator and sorted into the sliding device for inclusion into the remaining operational flow of the conveyor line, taking into consideration the associated station number appearing on the station number indicator.
