Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a turret machine provided with a plurality of bobbins for winding a yarn, which has been subjected to a spinning process and a drawing process, to a bobbin. It is rotatably provided so as to be displaced between the winding position and the non-winding position, and the yarn is applied to the upstream side of the bobbin in the winding position in the winding direction by the traverse blade within the winding width in the axial direction of the bobbin. In addition to providing a traverse mechanism that reciprocally moves by engaging and locking, a thread guide member that restricts the movement of the thread that is abuttingly locked by the traverse blade within the winding width is provided, and the thread that moves relative to the bobbin at the winding position It is also possible to provide a yarn guide for moving the yarn guided by the yarn guide member to the outside of the winding width after the empty bobbin on which the yarn is not wound and the wound bobbin is displaced to the winding position. Relates to a winding device of the yarn having a yarn hooking guide for guiding the yarn moves outside the winding width to the grip portion of the empty bobbin.

[0002]

2. Description of the Related Art As a yarn winding device as described above, a device disclosed in JP-A-1-187182 has been known.

In this conventional example, when a set amount of thread is wound around a bobbin, the fully wound bobbin is replaced with an empty bobbin, and the thread is wound around the empty bobbin, the turret board is rotated to empty the bobbin. After displacing the bobbin to the winding position, the thread moving guide moved the thread to the outside of the winding width in the direction of the rotation axis of the bobbin, and the thread hooking guide guided the thread to the empty bobbin gripping part. ..

Usually, in order to move the yarn back and forth within the winding width of the bobbin in the direction of the axis of rotation of the bobbin,
Providing traverse blades that rotate in mutually opposite directions, at each end of the winding width, the yarn is passed from one traverse blade to the other traverse blade, and either one of both traverse blades is abutted and locked to the yarn. Along with the guide reciprocating movement, a yarn guide member is provided on the upstream side in the yarn winding direction or the like to prevent the yarn from coming off the traverse blade so that the movement of the yarn is restricted within the winding width.

During the movement of the above-mentioned yarn pulling guide, the yarn abutted and locked by the traverse blade along with the movement is forcibly removed from the traverse blade.

[0006]

However, in the conventional structure as described above, when the yarn is forcibly removed from the traverse blade by the movement of the yarn guide, the yarn is handled by the traverse blade to generate fluff, Since the fluff generation part cannot be used as a product, there is a drawback that the yarn of the entire bobbin is wasted.

Further, since the thread remains locked on the traverse blade and cannot be removed, it cannot be hooked and locked on the empty bobbin, resulting in defective switching from the fully wound bobbin to the empty bobbin. Due to such a switching failure, the operation of the apparatus must be interrupted and the empty bobbin must be artificially threaded, resulting in a decrease in workability.

The present invention has been made in view of the above circumstances, and is capable of favorably switching a yarn from a fully wound bobbin to an empty bobbin without the traverse blade interfering with the yarn. The purpose is to be able to.

[0009]

In order to achieve the above-mentioned object, the present invention provides a turret board provided with a plurality of bobbins for winding a yarn, and a bobbin winding position and a non-winding position. It is rotatably provided so as to be displaced to and from the bobbin at the winding position and upstream of the bobbin in the winding direction of the bobbin. In addition to providing a moving traverse mechanism, a yarn guide member for restricting the movement of the yarn abuttingly locked to the traverse blade within the winding width is provided, and the winding of the yarn on the bobbin at the winding position is completed. When the empty bobbin that has not been wound is displaced to the winding position, a thread guide that moves the thread outside the winding width is guided by the thread guide member. The winding apparatus of the yarn having a yarn hooking guide for guiding movement yarn to gripper empty bobbin,
The yarn guide member is provided so as to be displaceable by a drive mechanism between a contact position where the yarn within the winding width contacts the traverse blade and a non-contact position where it does not contact the traverse blade, and a yarn pulling guide from the initial position to the winding width. It is configured to include a control device that operates the drive mechanism to move the yarn guide member to the non-contact position when moving to the outside.

[0010]

According to the structure of the yarn winding device of the present invention, when the yarn guided by the yarn guide member is moved to the outside of the winding width by the yarn guide, the yarn guide member is not in contact with the yarn. Since the yarn is moved to the outside, the yarn can be moved outside the winding width without contacting the traverse blade.
