Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field 1] The present invention relates to the control of a traverse moving device installed in a yarn winding machine. More specifically, the present invention relates to a traverse control method for winding while correcting an error between a set traverse stroke length and an actual stroke length.

[Prior art and its problems] In yarn winding machines such as spinning winders, drawing machines, and twisting machines,
The handling in the next process differs depending on the type of yarn to be wound, and therefore the desired package shape differs. In addition, a movement vj that gives a desired stroke to the rubber movement to one of the yarns is performed.
The driving means for the device includes a hydraulic cylinder and an electric motor. These drives allow ring rails,
The traverse cam, rack, and other mechanisms were activated to wind up the package into the desired shape. However, these mechanisms require complicated mechanisms and cannot be formed into arbitrary shapes, which limits the package form.

Therefore, recently, attempts have been made to obtain an arbitrary package shape using a memory device for 1 to rubber folding position setting values, an arithmetic processing unit, an input/output converter, and a traverse position detector. However, the actual value (stroke length) may differ from the set value input into the storage device due to a delay in the response of the hydraulic system or backlash of the electric motor.
A trial roll was necessary. There is also a problem in that the values change over time, and the input set value needs to be corrected each time.

[Object of the Invention] The present inventors have investigated a method for eliminating stroke length errors in a traverse mechanism that can eliminate the above-mentioned drawbacks and easily obtain various desired winding shapes. The present invention has been achieved.

[Structure of the Invention] That is, the present invention provides a yarn winding machine that winds up a yarn while traversing it using a traverse mechanism driven by a hydraulic pressure or an electric motor. ~The rubber turn-back setting value is input into the storage device, and when the yarn is wound, the pile length of the traveling yarn being wound and the traverse turn-back position are detected and input to the calculation processing unit to calculate the value. Then, input it to the error correction calculation device, calculate the error between the input value and the set value, output the return correction command value corresponding to the error value to the traverse movement device through the input/output converter, and perform the traverse. This is a traverse control method for a yarn winding machine characterized by controlling the amount of movement.

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

This is a control device that will be described later.

In order to detect the value of the cumulative length of the running yarn, a slit plate 13 is provided on the shaft of the yarn supply roller 1 ( ), and a rotation detector is provided near the slit plate 13 .

The rotation detector 12 is a well-known magnetic type that generates pulses when rotated. The rotation detector (1) is converted into the length of the running thread.The position detector (14) is the one that generates the -no pulse, which is the amount by which the ring rail has moved.

The yarn Y is supplied from the yarn supply row 51, wound around a stretching bin, and stretched by the stretching roller 4 whose circumferential speed is higher by the desired stretching ratio valve. be done. The hot plate 3 is for heat fixing. The drawn yarn passes through a traveler (not shown) in a ring 5 and is wound around a bobbin 8 attached to a spindle 6.

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

Reference numeral C is a storage device in which an arbitrary pattern of ring rail movement amount and running cumulative length of running yarn can be numerically input as shown in Fig. 2 in the input data section, and a large number of arbitrary patterns can be stored. =4= can be done. B is an input/output converter that converts pulses from the rotation detector 12 and position detector 13 into pulses suitable for the arithmetic processing unit Δ, which will be described later, and converts the output from the arithmetic processing unit A to the ring rail security device 10. This converts the amount of movement into an output that is suitable for the amount of movement.

A is an arithmetic processing unit that receives pulses from the rotation detector 12 through the manual saw converter B, converts them, and sends them to the error correction calculation device E.

Reference numeral E denotes an error correction calculation device, which calculates the difference between the traverse return setting value inputted from the calculation processing section A and the actual 1-traverse position measurement calculation value, and inputs that value to the calculation processing section.

D can specify the pattern of the input data section C to the arithmetic processing section 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 the pattern (a) of the moving amount of the ring rail and the cumulative running length of the running yarn to wind it into this shape. Fig. 3 is a front view showing an example of a warp winding package. , a is a bobbin, and b is a wound yarn. FIG. 4 is a diagram showing an example of error correction calculation in FIG. 2.

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 is performed as follows.

The fraud processing section A reads the ring rail movement@amount setting value Lo when the running cumulative length of the running yarn is M+ from the pattern shown in FIG. For the traverse position, the pulse integrated value from the rotation detector 12 is read, and for the traverse position, the pulse from the position sensor 14 is read by input from the input/output converter B, respectively.
Calculate and check whether there is any error between the input calculated measurement value 1i of the traverse position for the yarn length and the set value Lo,
If there is no error, the set value Lo is set as the command value Ll, and the ring rail is raised by outputting it to the ring rail lifting device 10 through the input/output converter B. As the ring rail rises, a pulse is generated from the position detector 14, and this pulse is input to the arithmetic processing unit through the input/output converter B, and this process is repeated.

Here, the set value Lo when the running cumulative length Mi of the ring rail movement amount and the corresponding input calculation measurement 18 Li
The case where there is an error between the two will be explained using FIG. The calculation processing unit A reads the input calculation measurement value [i,
The value and the set value Lo are input to the error correction calculation device E.

Then, the new value calculated by the error correction calculation device @E is read into the arithmetic processing unit, and the new value 1- is passed through the input/output converter B again to the ring rail lifting device 10.
Output to. As a result, the ring rail operates under the control of the new corrected command value.

The correction in the error correction calculation device E is as follows: 11° Input calculation measured value: Li Pre-input setting value: 1-0 7- Error value: Δl- New correction command value: L, Δl = (Li -1o)/2l-1-o-8 is preferable.

Thus, each time the ring rail moves up or down, the amount of ring rail movement is determined by the amount specified on keyboard D from FIG.
The ring rail movement amount corresponding to the running cumulative length of the traveling yarn and the pulse cumulative value from the rotation detector 12 are sent to the arithmetic processing section. The error correction calculation device E determines this value and uses that value as the next command value. The signal is output to the ring rail lifting device 10, and 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 integrated length of the traveling yarn, the winding device is stopped, thereby obtaining a package having the desired yarn length and warp winding shape. .

Furthermore, in order to detect the running cumulative length of the running yarn, in addition to the supply roller illustrated in FIG. 1, a stretching roller or a separation roller (not shown) can also be used.
Other known running yarn length measuring devices may also 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 spinning winder, a winder for drawing and splitting, and a cone winder.

[Effect of the invention 1] As described above, according to the present invention, the drive system of the traverse mechanism can be adjusted to various hoisting shapes without requiring any mechanical changes by simply providing an error correction calculation device. There is no hole in the package shape due to response delay, there is no need for test winding, and there is no change during light hours, which brings a remarkable effect on package winding.
