STORAGE AND ACTIVE TYPE YARN FEEDER

摘要

A storage and active type yarn feeder is provided to stock the original yarns simply and stably to a storing member by a leading member. An inside controller(450) has a stroke sensor(420) for checking the lead distance in order to control the start and stop of a motor in response to the timing of the reverse spiral movement and spiral movement. The inside controller is embedded into a holder member(100). A storing member(200) is rotatably combined with the holder member and controlled by an electromagnetic type of emergency braking device. A lead member(300) is combined at the upper portion of the storing member, and performs a reverse spiral motion by means of the motor and a spiral motion when stopping the motor along the rotation direction of the storing member. A sensor member(400) is installed at the holder member and offers a signal according to the operation state of the lead member to the inside controller. The lead member is independent of the storing member functionally.
