Container transfer mechanism between conveyors - has suction cups each connected to separate chamber with cam-operated piston

摘要

At least one of the conveyors being curved and having pockets for the containers. These are gripped by suction cups bearing against their sides and deflected from the first to the second conveyor. Each cup (9) is connected to a separate vacuum chamber (12), which comprises a cylinder (13) in which a piston (14) moves up and down, being brought into the suction and release positions by a cam track (16, 17). The conveyor can be circular, having corresponding circular vacuum chambers at the centre, above which is a control rail (18) with cams brought into engagement with the pistons, so as to exert suction during transfer and eject at the discharge point.
