Abstract:
An ordering device for arranging products received from a feed device in an orderly succession to feed an operating machine, the device comprising first and second conveyor means, having belts closed in loops and aligned with one another to define a product feed path with preset total length, said path including first and second active portions with variable lengths equaling complementary fractions of the total length; transmission means being connected to the belts to define the first and second active portions and supported by a carriage, the latter moving in both directions parallel with the path; drive means operating on the carriage to move the transmission means so as to vary the length of the first and second portions; compensator means for compensating the variations in the length of the active portions of the path with corresponding opposite variations in the length of complementary sections, respectively active and passive, of the belts, the ordering device comprising a single carriage, the compensator means comprising mechanisms respectively equipped with rigid elements, the latter being joined to one another to form a linkage connecting the carriage to the belts in such a way as to vary the geometric configuration of the belts according to the movements of the carriage.
