Abstract
A folding apparatus (30) having at least one conveyor belt (10) which is used to convey signatures (64) at least on a section of a path (66, 68) of the signatures (64) through the folding apparatus (30). The folding apparatus (30) features at least one monitoring device (12) with which the conveyor belt (10) is associated. The monitoring device (12) contains a detector (20) for radiation (22) scattered from at least a part (24) of the conveyor belt (10). The condition of the conveyor belt (10) can be determined and classified in an advantageous manner so that the machine operator can receive a signal for timely replacement so as to avoid an unexpected breakage of the conveyor belt (10).
Claims7
A folding apparatus comprising:
- a conveyor belt for conveying signatures at least on a section of a path of the signatures through the folding apparatus, and
- a monitoring device monitoring the conveyor belt, the monitoring device including a radiation emitter emitting radiation toward the conveyor belt and a radiation detector receiving the radiation scattered from the conveyor belt, the radiation emitter and radiation detector being located on a same side of the conveyor belt.
A web-fed printing press comprising:
- at least one downstream folding apparatus having at least one conveyor belt for conveying signatures at least on a section of a path of the signatures through the folding apparatus, and at least one monitoring device associated with the conveyor belt, the monitoring device monitoring the conveyor belt, the monitoring device including a radiation emitter emitting radiation toward the conveyor belt and a radiation detector receiving the radiation scattered from the conveyor belt, the radiation emitter and radiation detector being located on a same side of the conveyor belt.
A method for monitoring deterioration of a conveyor belt in a folding apparatus comprising the steps of:
- emitting radiation toward a side of the conveyor belt,
- receiving radiation bouncing off the side of conveyor belt on the same side of the conveyor belt;
- generating a signal representative of a condition of the conveyor belt as a function of the received radiation;
- and
- assigning the signal to a condition class.
