ABSTRACT:
My conveyor comprises an associated track-bound car including a drive motor supplied with drive current by current-carrying rails, a container, and a cover for the conveyor, as well as a track on which the conveyor runs by a plurality of stations. In order to prevent unauthorized opening of the cover a latch of a locking mechanism mounted in the track-bound car is restrained in a locked configuration. The latch can be unlocked by an electromagnetic unlocking mechanism mounted in the track-bound car. A very simple control of the unlocking mechanism can be provided, when, at a position or station in the conveyor where it is to be unlocked, an unlocking signal generator is present, which is automatically connectable with the track-bound car, in order to supply the unlocking mechanism with a required unlocking current.
