PURPOSE:To enable only the required cargoes to be driven and save energy by means of such constitution that a transmission roller is brought into contact with a conveying roller through a turning frame by descending motion of a pallet of a roller which is movable downward and constantly protruded from the passing space under the lower side of the pallet. CONSTITUTION:Normally a detecting roller 9 is protruded through a movable frame 8 over the lower passages P-Q of a pallet by the weight of a motor 12, a transmission roller 11 is released from a conveying roller 4, and a brake 14 is brought into contact with the conveying roller 4. And when the pallet depresses the detecting roller 9, the brake 14 is released through the movable frame 8, and the transmission roller 11 is brought into contact with the conveying roller 4, which drives the conveying roller 4 and conveyes the pallet. Besides, the conveying roller 4 can be driven regardless of movement of the detecting roller 9 by connecting the movable frame 8 of the necessary drive unit D through a connecting rod 16 to a treadle gear. Thus, energy saving, free selectivity of length and width of the machine can be improved, and noise can be prevented, by distributing the driving power per each unit D of the conveyor. |
