Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field 1] The present invention relates to a traverse method in a yarn winding device. More specifically, the present invention relates to a traverse method for winding up a package of a desired shape by changing the stroke length of the traverse.

[Prior art and its problems] In a yarn winding device, the desired package shape differs depending on the type of yarn to be wound depending on the handling in the next process, etc. Therefore, as a means for giving a desired stroke to the traverse movement of the yarn, Conventionally, for example, in a yarn twisting machine, a four-fall traverse cam of a ring rail, a rack, and other various mechanisms were used to wind up a package in a desired shape, but this required a complicated mechanism, and the cam method was not sufficient. In this case, it is not possible to take any arbitrary shape, and the package is limited to 71 ohms. Further, it is not easy to arbitrarily select various shapes using a counting device, and furthermore, the device is complicated and it takes time to set conditions, and there are many problems in that parts fail. In addition, there was a problem in that test winding had to be performed due to lack of reproducibility.

[Purpose of the Invention] The present inventors have arrived at the present invention as a result of intensive study of a traverse method that eliminates the above-mentioned drawbacks and can easily create various desired winding shapes.

[Structure of the Invention] That is, in the yarn winding device of the present invention, the 1-rubber turn-back position corresponding to the value of the running length of the running yarn is input in advance into the storage device, and the yarn is processed. When winding, the length of the running yarn being supplied and the pulse of the traverse turn-back position are input to the storage device and calculated, thereby calculating the command voltage of the traverse turn-back position corresponding to the length of the running yarn. Output to traverse moving device,
This is a traverse method for a yarn winding device, characterized in that the yarn is traversed and wound according to the yarn length of the traveling yarn.

Hereinafter, the present invention will be explained based on the drawings.

FIG. 1 is a schematic diagram of a draw-twisting machine which is an embodiment of the present invention. In FIG. 1, 1 is a yarn supply roller, 2 is a drawing pin, 3 is a hot plate, 4 is a drawing 1]-ra, 5 is a ring, and 6
1 is a spindle which is a bobbin holder, 7 is a drive belt for the spindle, 8 is a bobbin for winding a thread, 9 is a ring rail for traversing the yarn, 10 is a ring lifting device, 11
12 is a rotation detector, 13 is a slit plate, 14 is a position detector, and 15 is a control Il device to be described later.

A slit plate 13 is provided on the shaft of the yarn supply roller 1. A well-known magnetic rotation detector 12 that generates pulses when the slit plate 13 rotates is provided near the slit plate 13. The position detector 14 generates pulses corresponding to the amount by which the ring rail moves.

The yarn Y is supplied from a yarn supply roller 1, wound around a stretching bin, and stretched by a stretching roller 4 whose circumferential speed is faster than the peripheral speed of the yarn supply roller 1 by a desired stretching ratio valve. The hot plate 3 is for heat fixing. The stretched yarn is ring 5
Traveler (Illustrated) @ I¥-C, if < e
'>4,)>T'a-i3' is wound around the bobbin 8 attached to the spindle 6=3-.

The control mechanism of the control device 15 shown in FIG. 1 is as follows.

C is a storage device (ROM) in which an arbitrary pattern of the movement amount of the ring rail and the running cumulative length of the traveling thread can be numerically input as shown in Fig. 2 in the input data section, and a large number of arbitrary patterns can be input. It can be stored.

B is an input/output converter that converts pulses from the rotation detector 12 and position detector 14 into pulses suitable for the arithmetic processing section described later, and outputs from the arithmetic processing section to the ring rail lifting device 10. This converts the amount of movement into an output that is suitable for the amount of movement.

A is an arithmetic processing section that calculates the yarn length by receiving pulses from the rotation detector 12 through the input/output converter B, and calculates the movement amount of the ring rail based on information from the input data section C. Then, by receiving pulses from the position sensor 14 through the input/output transducer B, the amount of movement of the ring rail is determined.

4-D can specify the pattern of the input data section C to the arithmetic processing section A using the keyboard.

Next, the operation of warp winding will be explained as an example of winding a package of arbitrary shape. FIG. 2 is a diagram illustrating a pattern of the movement amount of the ring rail and the cumulative running length of the running yarn for winding into this shape. FIG. 3 is a front view showing an example of a warp-wound package, in which a is a bobbin and b is a wound yarn.

Specify the pattern shown in Figure 2 above from keyboard D,
Let us consider the case where the movement position of the ring rail matches the winding start position of bobbin a. The first ring rail movement amount is determined by the calculation processing unit △ which uses the pattern shown in FIG. The ring rail movement when the value M1 is read and the number of people is 1. By outputting the signal to the ring rail lifting device 10 through the force converter B, the ring rail rises and starts winding.

A pulse is generated by the position detector 14 due to the earthen structure of the ring rail, and this pulse is input to the arithmetic processing section Δ through the input/output converter B. Ring rail movement fjAt
When the number of pulses corresponding to q is input to the arithmetic processing section,
The arithmetic processing unit A outputs an output for causing the ring rail to become untimely and an output for the next ring movement.

Thus, the amount of ring rail movement each time is determined from the figure 2 specified on keyboard D by the amount of ring rail movement when the running total length of the running yarn corresponds to the integrated pulse value from the rotation detector 12. The arithmetic processing unit Δ determines this and outputs it to the ring rail elevating/lowering gm1o, so that the above operations are repeated one after another.

Then, when the pulse integrated value of the rotation detector reaches the value Mn of the running yarn running integrated length, the winding device is stopped, thereby obtaining a package having the desired yarn length and warp winding shape. .

In addition, in order to detect the cumulative length of the running yarn, in addition to the supply roller illustrated in FIG.
(not shown) may be used, or other well-known running yarn length measuring instruments may be used.

Although FIG. 1 shows an example of a draw-twisting machine, it goes without saying that the present invention can be applied to winding devices such as a winder for drawing and splitting, a cone winder, and the like.

[Effects of the Invention] As described above, according to the present invention, for various winding shapes such as warp winding and filink winding, it is possible to simply calculate the relationship between the running cumulative value of the running yarn and the ring rail movement amount. By inputting numerical values into the storage device of the input data section C and selecting an arbitrary winding shape pattern from the keyboard D as necessary, the desired shape of the package can be created without requiring any mechanical changes. It is particularly effective for winding up packages of this type.
