Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention consists of supplying a full tube yarn wound in a spinning machine to a winder in the next process, and returning an empty wood pipe sent out from the winder to the spinning machine. This invention relates to a lift device used in a bobbin circulation device to lift a full yarn to the upper front of a spinning machine.

[Conventional technology and its problems] Since a spinning machine winds up a large amount of full-tube yarn at one time, conventionally the full-tube yarn doffed by an automatic doffing machine was stored in a storage box and transported to the winder by a worker. In order to save labor, a storage conveyor was developed that temporarily stores full yarns and then transports them one after another. However, installing a storage conveyor requires a large floor area between the spinning machine and the winder, and there are other problems such as yarn collapse and fluffing due to the contact of the pipe yarns during storage, and difficulty in pulling out yarns due to entanglement of yarn ends. .

An object of the present invention is to provide a full yarn lift device for use in a bobbin circulation device that solves these problems.

[Means for solving problems]

In the bobbin circulation device of the present invention, a guide rod is attached to the inner wall of the auto-dolpher and a groove-shaped lifter rod is covered, a first winding conductive member is mounted above and below this inner wall, and this conductive member is set. A second winding conduction member is connected to the lifter rod by a piece, and is hung on a movable ring suspended from the top end of the lifter rod, one end of which is fixed to the dotshua, and the other end of the conduction member is attached to a gripper for full yarn. and is tied to the side plate that moves up and down along the lifter rod.

A full yarn conveyor C2 is mounted on the upper front side of the spinning machine, and a wagon-type auto-transfer D is run along the front of the spinning machine table.

In the spinning machine F, the hollow wood tubes inserted into each spindle P rotate at high speed, and when the hollow wood tubes wind the yarn to form a full yarn, the spinning machine F stops its operation. Next, the auto-transfer D runs and extracts several spindles of the full yarn from the spindle, lifts it up, and inserts it into a peg (not shown) of the full yarn conveyor C2. When the auto-transfer D advances to the left one after another and finishes transferring the full yarn for one spinning machine to the conveyor C, this conveyor advances to the right and supplies the full yarn to the winder W. When the full yarn of the spinning machine is doffed, the empty wood tube conveyor C1 starts to move to the left, and the empty wood tube of the full yarn used last time in the winder W is inserted into the peg at the starting end of the conveyor C1. The empty wood pipes for one spinning machine were returned near the floor. Once this is completed, the worker inserts the hollow wood tube into the spindle, and the spinning machine F resumes operation and winds the yarn.
