Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a winding device for winding yarn upward from a supply tube yarn inserted into a peg.

In cheese or corn after dyeing, shrinkage of the threads due to dyeing and circulation of the dye solution cause disturbances in the winding layer, especially in its surface layer, and the threads become entangled with each other, causing the threads to break when unwinding. In addition, the unraveled yarn loop pulls out other yarn loops, causing so-called sluffing, and this sluffing can be drawn to the yarn guide in the yarn running path, causing the yarn to break. It was hot.

The present invention is particularly designed to prevent the interruption of the winding yarn due to sluffing, and the outer shape of the supply tube yarn cone, which is inserted into the peg and winds the yarn upward, has a smaller diameter at the lower part and gradually increases from the upper part. It is characterized by having a large diameter, and the ballooning that occurs during winding is brought into contact with the yarn layer in the upper large diameter part of the tube yarn, giving resistance and impact to the winding yarn, thereby unraveling the entangled yarn and eliminating its tangles. This prevents the occurrence of unraveling sloughing.

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a winding device in which a yarn a is unwound upward from a supply pipe yarn 2 inserted into a peg 1, passed through a predetermined path, and then wound from a drive drum 3 onto a package 4.

In the present invention, the outer shape of the cone 5 of the supply tube yarn 2 in the above-mentioned yarn winding device is formed such that the lower part has a small diameter and the upper part has a gradually larger diameter.Therefore, the yarn layer is also formed to have a gradually larger diameter in the upper part. .

In this case, the ballooning of the yarn a that is pulled upward and unwound comes into contact with the yarn layer in the upper large diameter part of the tube yarn 2, so the winding yarn a creates resistance to the unwinding and is prevented from becoming entangled due to the impact caused by the contact. Since the threads that are unwound in this state are loosened and the threads are untangled, the occurrence of sluffing can be effectively prevented.

Fig. 2 shows an example of a mechanism for securely inserting and holding the pipe thread 2, which has a gradually larger diameter at the upper part, into the peg 1. 6 is provided, and the upper end of the rotating piece 8 whose middle is pivotally supported on the base plate 7 to which the peg 1 is attached is formed into a suppressing piece 9, which is positioned in the recessed notch 6, and the upper end of the rotating piece 8 is By bringing the other end 10 into contact engagement with a pushing member 13 that is pressed forward by a spring 12 in a fixed cylinder 11, the rotation piece 8 is rotated clockwise in the figure by the spring 12, and the upper end The suppressing piece 9 was energized so as to protrude outward from the recessed part 6 of the peg 1.

In this way, the suppressing piece 9 protruding from the notch 6 rotates the rotating piece 8 so as to be thrown into the notch 6 against the resilient spring 12, and the pipe thread 2 is pushed into the peg 1 as shown in the second figure. When the rotating piece 8 is released, the suppressing piece 9 comes into pressure contact with the inner wall surface of the cone 5 under the force of the spring 12, and holds the pipe thread 2 immovably, and the pipe thread 2 is taken out from the peg 1. When the rotating piece 8 is rotated against the spring 12, the suppressing piece 9 is retracted into the notch 6, so that the pipe thread 2 can be easily removed from the peg 1. Incidentally, a flexible material 9' is attached to the suppressing piece 9 to ensure suppression of the cone 5. The insertion and retention of the tube thread 2 into the peg 1 is not limited to the above embodiment, and other means may be adopted as appropriate.

In this way, according to the present invention, the outer shape of the cone of the supply pipe yarn is formed to have a smaller diameter at the lower part and a larger diameter at the upper part during the winding operation, thereby reliably preventing the occurrence of sluffing when the yarn is unwound from the pipe yarn. It has the effect of achieving the desired purpose with extremely simple means.
