ABSTRACT OF THE DISCLOSURE An improved conveyor drive unit (150) with a method of operation thereof, which can be rapidly and easily mounted on a roller-type conveyor system and which, when arranged in series, can be sequentially stopped and restarted relative to predetermined parameters in the article flow along a conveyor path (56). In one embodiment, each drive unit (150) has an arm (52) which extends at a desired distance over an article conveyor path (56) which can be tripped at the occurrence of accumulation. A pneumatic valve (68) is operably coupled to the arm (52) for releasing air into an actuating cylinder (78) having operably coupled thereto a shifter rod (92). The shifter rod (92) is axially displaced by the actuating cylinder (78) which in turn releases a drive collar (102) from a keyed sprocket of the pinion gears (18) of a transfer mechanism or "module" (1) of the conveyor system. When the drive collar (102) is disengaged, the operation of transport mechanism or module (1) is thus halted. When normal article flow is to be resumed, the drive collar (102) is engaged to the sprocket and the transport mechanism or module (1) is restarted. Instead of an arm (52) operable coupled to the pneumatic valve (68), article sensing (180), counting and timing (218) devices operably coupled to solenoid valves (192) are used in other embodiments.
