ABSTRACT:
An apparatus for guiding a series of objects, such as glass bottles, from a conveyor and advancing said objects stepwise between a plurality of inspection stations, and then returning said objects to said conveyor. The apparatus comprises a continuously driven feed mechanism cooperating with an arrangement for feeding the objects stepwise between the inspection stations, and is arranged to be placed adjacent the conveyor to receive objects from the conveyor. The feed mechanism synchronously and with great accuracy are arranged to feed objects to a receiving position and to feed objects from a dispatch position of the arrangement for feeding the objects stepwise between said inspection stations. The arrangement being arranged to feed said objects stepwise in opposite directions along two parallel paths by an elongate carrier arranged between the paths and having dogging arms projecting outwardly therefrom substantially perpendicualrly to the paths, and which carrier is adapted to execute a continuous parallel movement in a closed path in a manner such that during one half of the movement cycle the dogging arms are caused to move objects located on one path through one step in one direction and during the other half of said cycle to move objects located on the other path through one step in the opposite direction. The apparatus further comprises a continuously driven subsystem for transferring the objects from the terminal end of one of said parallel paths to the commencement end of the other of said paths.
