Control method for a collective packaging machine.

摘要

A control method of operation of a collective packing machine is provided. The 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 said main packing machine. When the auxiliary packing machine is at stop waiting state, revolution speed of a main shaft of the main packing machine and revolution speed of an input shaft of a clutch of the auxiliary packing machine are controlled in matching. 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 normal operation starting time by time tB. Said time ts depends on 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; and after finishing to connect the clutch, the main packing machine and the auxiliary packing machine are controlled in synchronization.
