<p>In apparatus for the signaling of a back-up in a container conveyor, the actual translation speed of all containers passing a measuring zone is determined separately with the aid of the measuring of the transit time and compared with the simultaneously measured momentary travel velocity of a hinge-belt-chain conveyor. If the translation speed of the containers is smaller by a determined amount than the travel velocity, or in a predetermined relationship, a jam or back-up signal is produced. The device has two photodetectors arranged at the same level with a fixed spacing in the direction of bottle transportation. A sensor registers the presence of a bottle in the measuring zone. A tachometer generator is attached to the drive shaft of the conveyor and provides an analog signal to a processor indicative of conveyor speed. patents.7.1 docket.no.397</p> |
