Document Type and Number:
WIPO Patent Application WO/1997/028912
Kind Code:
A1
Abstract:
Synchronous operation of a press unit and a feeder unit at the time of power failure is ensured by means of a very inexpensive structure. In a portion of a feeder line extending to a servomotor in a feeder unit (2), a capacitor for supplying power to the servomotor at the time of power failure is provided. A power failure detector and an uninterruptive power source for supplying power to a control system (feeder controller, relay logic or the like), which controls the servomotor when power failure is detected by the power failure detector, are further provided.
