OPERATION MACHINE IN SPINNING MACHINE

PURPOSE:To stop waste traveling, by equipping a drive circuit for a running motor of operation machines with a timer to set an operation interval of the operation machines and continuing stopping of traveling of the operation machines until time of the timer is up after operation completion. CONSTITUTION:Operation machines AD, AC, AD and ST such as wagon type doffing machines, etc., which travel along end parts of machine stands of a spinning machine group G wherein a large number of spinning machines SF 1-SFn are laid in parallel, approach the spinning machines to carry out operations such as doffing, cop exchange, ending, etc., and operate, a drive circuit for running motor of the operation machines is equipped with a timer and the running motor is not driven until time of the timer is up. Time set in the timer is time for operation interval. The operation machines always traveled conventionally even after operation completion.
