Abstract
A control method of operation of a collective packing machine, which packing machine is composed of a main packing machine and an auxiliary packing machine. The main packing machine is in continuous operation while the auxiliary packing machine is in stop waiting operation wherein the auxiliary packing machine is operated in matching and synchronization with the main packing machine. When the auxiliary packing machine is at the stop waiting state, the revolution speed of a main shaft of the main packing machine and the revolution speed of an input shaft of a clutch of the auxiliary packing machine are controlled by comparing and matching therebetween. When an output shaft of the clutch is stopped and operation of the auxiliary packing machine is started, operation starting time of the auxiliary packing machine is made earlier than the normal operation starting time by time t.sub.s. The time t.sub.s depends on the operation speed of the main packing machine so as to enable synchronization of the main packing machine with the auxiliary packing machine at the time of finishing to connect the clutch of the auxiliary packing machine. After finishing to connect the clutch, the main packing machine and the auxiliary packing machine are controlled in synchronization.
