ABSTRACT:
In the case of a device for mechanically accepting empties, more particularly bottles subject to a deposit, with a conveying device and a sensing device associated therewith, a high degree of reliability and a simple design are made possible inasfar as such conveying means comprises a conveying passage which comprises two parallel sections which are offset in relation to each other in the direction of conveying and have conveying belts placed side by side and arranged to be driven at different speeds, and an intermediate member extending obliquely in relation to the direction of motion of the conveying belts so as to bridge over a gap between the adjacent conveying belts, an outlet end part of the section with the more rapid conveying belt under it extending past the sensing means, which has a number of vertically offset sensing elements, aligned so as to be generally parallel to the plane of conveyance and adapted to sense the diameter of the empties.
