ABSTRACT:
In the context of a device for mechanically receiving empties in the form of bottle crates and other containers for bottles subject to a deposit, comprising a frame, at least one conveying device forming the lower limit of a conveying passage and which is adapted to move the empties past a sensing device improved functional reliability is achieved by an arrangement in which the sensing device comprises a sensing head extending over the conveying device, said sensing head being able to be raised and lowered by means of an actuator operated by the passage of an article moved by the conveying device and cooperating with a measuring device responding to its stroke, said sensing device comprising sensing elements arranged in the form of a row arranged to extend perpendicularly to the direction of conveying and arranged in relation to a fixed plane of an aligning device aligning the passing articles so as to be parallel to the conveying direction, said sensing elements being arranged to be actuated by articles under them and cooperating with a counting device.
