PURPOSE:To simplify the structure of the drive unit of a multirow conveyor, used in such as an assembling line, by making a friction gear of each conveying belt of the multi-row conveyor can be pressed against a common driving shaft selectively, by forming a driving pulley, which has the said friction gear, as it can be rocked individually. CONSTITUTION:A friction gear 10 is pressed against a driving shaft 8, which is always rotating, by making a selected conveyor 3 rock an arm 13 upward, by the power of an air cylinder 15, and a driving pulley 6 is made to rotate. In this way, a specific conveyor 3 of the multi-row conveyor can be driven selectively. If the friction gear 10 is separated from the driving shaft 8 by the arm 13, the conveyor 3 stops. In this mechanism, the structure of the drive unit can be simplified. |
