Control mechanism for at least one draw=in finger of fixed tray conveyor

摘要

The control mechanism has a crank shaft (26) which is loosely mounted and which is swivelable between two end positions as a result of the force exerted on the draw-in finger (28). The end positions are determined by one or more fixed stop pieces against which the crank shaft holder (36) is placed. At least one of the stop pieces is adjustable in the crank shaft rotary direction. A remote-controlled operated bolt is inserted into the holder track. The crank shaft has a weight for fully or partly equalising the torque produced by the eccentric part (32) and/or draw-in fingers.
