CONSTITUTION:As for a taking-up suspension method for a pirn winder in which a yarn Y supplied from a yarn feeding package P is guided to a traverse guide 5 which is raised and lowered with a prescribed traverse width for a bobbin 2 erected by a spindle 1, and the yarn is taken up on the bobbin 2 revolved by the revolution of the spindle 1, taking-up is suspended by shifting the traverse guide 5 to the upper position from the upper end of the traverse width.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winder for guiding a yarn of a yarn supplying package by a traverse guide and winding it on a bobbin rotated by a spindle, and more particularly to a method for stopping winding of a winder.

[0002]

2. Description of the Related Art In a bun winder, as shown in FIG. 3, bobbins 2 are mounted on spindles 1 provided in multiple weights, and a guide bar 4 which is moved up and down by an elevating device 3 is provided on these bobbins 2. A traverse guide 5 that guides the yarn of the yarn supplying package P is provided for each weight on the guide bar 4, and the yarn Y of the yarn supplying package P is formed.
Is guided by the traverse guide 5, and the traverse guide 5 is raised and lowered by a predetermined traverse width,
The bobbin 2 rotated by the spindle 1 is wound to form a pan 6.

[0003]

In this pan winder, when the winding is stopped, the rotation of the spindle 1 is stopped, the lifting device 3 is stopped, and the traverse guide 5 is stopped. There is a problem that the thread hangs down. If the winding of the pan 6 is completed with the yarn hanging down, the hanging yarn becomes a problem in the post-treatment process, and even if the yarn is wound again after the winding is stopped, the hanging yarn will not move. It is not preferable because it is wound around the pan 6 regardless of the position.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a winder winding stopping method capable of preventing the yarn from hanging down from the pan when the winding is stopped.

[0005]

In order to achieve the above-mentioned object, the present invention guides the yarn of a yarn supplying package to a traverse guide which moves up and down with a predetermined traverse width with respect to a bobbin erected on a spindle. In a winding stop method for a bun winder wound around a bobbin rotated by a spindle, the traverse guide is moved to a position above the upper end of the traverse width and stopped when the winding is stopped.

[0006]

According to the above construction, when the winding is stopped, for example, immediately before or after the stop, the traverse guide is positioned above the upper end of the traverse width, whereby the yarn can be prevented from hanging down from the pan.

[0007]

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

In FIG. 1, the spindle 1 is rotated in contact with the belt in units of, for example, 8 spindles, although not shown,
The bobbin 2 mounted on the spindle 1 is rotated.

A traverse guide 5 for guiding the yarn Y from a yarn supplying package (not shown) is connected to the traverse bar 4 and is moved up and down by the elevating device 3 with a predetermined traverse width with respect to the bobbin 1. It is like this. That is, the traverse bar 4 has its both ends suspended by a belt 7 or the like so as to be able to move up and down, and the other end of the belt 7 is guided by pulleys 8 and 8 to be connected to a ball nut 9. It is provided by being screwed into a ball screw 11 connected to the forward / reverse rotation motor 10, and the forward / reverse rotation of the forward / reverse rotation motor 10 causes the forward / reverse rotation of the ball screw 11 and the upward / downward movement of the ball nut 9 to traverse the belt 7. The guide 5 can be moved up and down with a predetermined traverse width.

The rotation of the forward / reverse rotation motor 10 is detected by a sensor 12
The detected value of the sensor 12 is input to the control device 13. Therefore, the control device 13 can detect the position of the traverse guide 5 from the detection value of the sensor 12 and can control the rotation of the forward / reverse rotation motor 10 to freely set the traverse width. Further, the control device 13 controls a belt driving device (not shown) for rotating the spindle 1 so as to control the number of rotations of the spindle and to start and stop the device.

In the above, the spindle 1 is rotated,
The yarn Y from the yarn supplying package P is guided by the traverse guide 5, and at the position of the traverse guide 5, the yarn Y is wound around the bobbin 1 to form the awn 6.

Next, when the winding is stopped, the controller 1
3, regardless of the traverse position of the traverse guide 5, the traverse guide 5a is positioned at a position above the upper end of the traverse width, that is, a position where the bobbin 2 shown in the figure is subjected to a top bunch, and is stopped. By stopping the traverse guide 5a in this way, it is possible to prevent the yarn Y from hanging down from the pan 6. When the winding is stopped and the winding is completed, if the traverse guide 5a stopped at the upper position is left as it is and the spindle 1 is rotated as it is,
The top bunch 14 can also be formed.

Next, the winding and stopping method will be described with reference to the graph of FIG.

FIG. 2 shows an example in which the awn 6 is formed by warp winding. In the figure, a is a line showing the position of the traverse guide 5, and b is a line showing the change in the rotational speed of the spindle.

First, at the start of winding, the traverse width is set to the maximum width and wound on the bobbin 2, and then the traverse width is gradually narrowed. The spindle rotation speed is set as the winding yarn is wound on the bobbin 1. Since the speed becomes faster, the speed is gradually lowered so that the yarn is wound at a constant speed.

After that, when the winding is stopped, for example, when the winding is completed, the traverse guide position is raised to the position b of the top bunch further above the upper end position c of the traverse width at the start of winding and the position is maintained. Then, rotate the spindle as it is, apply a top bunch, and then stop.

Although FIG. 2 has been described with reference to the example of applying the tob bunch, even when the spindle 1 is stopped during winding, raising the traverse guide 5 to the position b of the top bunch and stopping it prevents the yarn from hanging down. Of course you can.

In the above embodiment, the warp winding is used as an example, but the same applies to other filling windings.

[0019]

In summary, according to the present invention, by suspending the traverse guide above the upper end of the traverse width when the winding is stopped, it is possible to prevent the yarn from hanging down from the pan.
