PURPOSE: To perform the conveying of article while restraining noises by controlling the drive of multiple pusher dogs to be turn around inside an annular guide and connected to each other by drag connection at a start and a terminal end between the conveying work blocks, and forming the drag connection with an elastic material. CONSTITUTION: A turn-around guide 12 is arranged in a frame 10, and multiple pusher dogs 14 are supported by the guide 12 freely to be slid. The pusher dogs 14 are secured to an endless toothed belt 16 with a constant distance, and the belt 16 is formed of a spring element to be extended and shrunken by the elasticity, and deformed into a wave shape by attachment elements 18. An entrainment member 20 is provided in both sides of each dog 14. Each rotary shaft 30, 32 is supported by each bracket arm 26, 28 provided in the frame 10. The rotary shafts 30, 32 are driven by motors 40, 42 through belts 36, 38. Controllers 44, 46 control the number of revolution of the motors 40, 42, and the drive of the pusher dogs 14 is controlled by the arms 26, 28 at a start and a terminal of the conveying work blocks. With this structure, the pusher dogs 14 are conveyed while restraining the noise.
