Abstract:
A conveyor with automatic-repositioning trippable pushers, set along a sliding surface (12) for products (13) that are to be moved onwards and comprising a continuous-drive element wound in a flattened loop (14) to which there may be constrained, at pre-chosen intervals, pusher assemblies (15), characterized in that each pusher assembly (15) consists of a carrying element (16) constrained to said continuous-drive element (14) by means of a pin (17) and of a pusher element proper (25, 125) that is trippable and comprises a base (26) and a shaped lever (27) that can oscillate (in 28) with respect to said base (26), there being provided elements of elastic engagement (34, 37, 38) between said carrying element (16) and said shaped lever (27) which keep said shaped lever (27) in a position of thrust against a pre-determined force, yielding when a greater opposing force is exceeded, there further being provided, on said lever (27), elements of engagement (31) with said continuous-drive element (14) at points corresponding to end pulleys (23) which automatically bring said shaped lever (27) that is oscillated and sent down back into an operating position, inserting again said elastic-engagement elements (34, 37, 38) between said carrying element (16) and said shaped lever (27).
