Abstract
An apparatus for taking out a molded product that is capable of suppressing displacement vibration of an attachment in a shorter time than ever without using a large-scaled electric actuator. An active controller starts active control after the amplitude of displacement vibration of the take-out head as an attachment has been attenuated to a predetermined setting by means of positioning control by a servomotor or when the amplitude can be considered as having been attenuated to the predetermined setting. The positioning control is first performed by the servomotor, and then the active control is performed by the active controller using an electric actuator which is light in weight and small in size.
Claims19
An apparatus for taking out a molded product, comprising:
- a positioning servo device using a servomotor;
- an approach frame controlled by the positioning servo device and having an attachment mounted thereon;
- a displacement vibration detector operable to detect a displacement vibration of the attachment;
- and
- an active controller including an electric actuator and configured to perform active control to suppress the displacement vibration of the attachment by causing the electric actuator to apply to the attachment a vibration having an antiphase to the displacement vibration detected by the displacement vibration detector, wherein:
- the active controller performs the active control after an amplitude of the displacement vibration of the attachment has been attenuated to a predetermined setting by a function of positioning control of the positioning servo device.
