[Detailed description of the invention] (A) Technical field of the present invention The present invention relates to a method for forming a tail of a yarn package.

(B) Prior art and its problems It is widely practiced to continuously wind yarn onto a bobbin using a yarn winder to form a yarn package. It has also been widely practiced to form a tail winding part at the end of the bobbin and then forming a yarn package body winding part on the bobbin to form a yarn baggage over the tail.

However, recently, with the development of a high-speed winder (+'PfT), in which the bobbin rotational speed of the yarn winding machine is extremely high, and its high speed has been gradually increased, the tail forming method using the conventional yarn winding machine has been In this case, the yarn winding density of the tail winding part that is formed becomes significantly high, and the length of the yarn winding in the tail winding part is markedly different from the conventional two-wrap length, which has been considered to be convenient. The difficulty of using it has come to the fore in many people.

This problem is especially true when the yarn is continuously formed from a spinning machine at a speed of 2,000 to 6,000 soo per hour, for example.

In particular, in a pirn-wound yarn package formed by a winder that continuously winds two windings in a pirn shape on a bobbin while slowly traversing the force of the bobbin at a speed of I ended up being asked 9 questions.

(C) Object of the Invention The present invention solves the above-mentioned problem of a yarn package having an overcrowded tail winding part (the total length of the yarn in this part is 7 to 10 meters), and This was removed for the purpose of providing a new method for separately forming a yarn package having .

(1)) Structure of the present invention In order to achieve the above object, the present invention has the following structure.

(b) Move the yarn suction tool relatively to the tail winding part of the yarn package, which is formed by the tail winding part formed by the winding machine and the yarn package main body winding part connected to the tail winding part formed on the bobbin. , move.

a step of suctioning and unraveling the yarn of the tail winding portion using the suction tool;

(b) A step of holding the suction-unwound yarn in a suction state with the suction tool in a state where it is connected to the winding portion of the yarn package main body.

(c) While maintaining the suctioned state, the bobbin and the suction tool are relatively rotated so that the thread is wound around the end surface of the bobbin. A method for forming a tail of a yarn package, comprising the steps of: winding the yarn around the end of the bobbin while drawing the yarn into a desired shape using the suction tool to form a desired tail winding portion.

(E) Embodiments of the Invention Next, the present invention will be further explained using one embodiment thereof with reference to one drawing. Figure 1 is.

1 is an overall schematic diagram of an implementation apparatus for implementing the method according to the invention; FIG. This device 100 includes a robot device 2 that can move an arm 1 horizontally in and out and up and down nine times, and a yarn suction device 6 attached to the tip of the arm 1.
Yarn guide arms 5a and 5b are located at both ends of the yarn suction device and are also attached to the tip of the arm 1 and have yarn guide grooves 4a and 4b at the tips that are swung open and closed by the robot 2. and a suction hose (not shown) with a clean inner surface that will not damage the yarn to be drawn out in reverse, which will be described later, and which is connected to the lower end filter a of the yarn suction device B, and an air suction connected to the suction hose. a yarn separation and collection device (not shown) that separates the air present in the suction hose from the yarn and captures the yarn on the side of the suction tool 3 from the air suction source; tape sticking means 8 that holds the tail tape 6 and moves in and out toward the bobbin 7; and the bobbin 7.
A yarn cutting means 9 that enters and exits the vicinity of the yarn and cuts the yarn.

A bobbin gripping means 1o is movably positioned above the yarn suction device and holds the bobbin 7 in a detachable manner. Also, in the vicinity of this device 100, a yarn package 1 in which yarn 11 is wound in a pirn shape on a bobbin 7 is provided.
There is a package storage section 13 in which 2 is placed. The yarn package storage section 13 includes an overcrowded tail winding section 14 formed by winding yarn onto a bobbin using a high-speed winder, and a yarn package body winding section 15. Additionally, a yarn package 12 having a punch winding portion 16 and a yarn package (not shown) having an appropriate tail winding portion 14a (see FIG. 4) formed by carrying out the present invention described below. is placed.

Next, the operation of this device 100 will be explained.

The bobbin gripping means 10 is moved to the package storage section 16 by a moving mechanism (not shown).

It descends from above, holds the yarn package 17 having the overcrowded tail winding section 14, rises twice, moves laterally, and stops above where the yarn suction device is located.

In this state, the arm 1 is raised by the operation of the robot 2 until the overcrowded tail winding portion 14 at the tip of the bobbin 7 is located in the suction cup at the tip of the yarn suction shell O, and then stopped. . Next, in this state, the operation of the yarn suction device 6 is started, and together with the suctioned air, the yarn of the overcrowded tail winding section 14 continues to be smoothly unwound in the axial direction of the bobbin 7. 2), when the yarn in the overcrowded tail winding section 14 is completely exhausted, the unwinding of the yarn automatically stops, and the yarn remains connected to the yarn package body winding section 15. The yarn is held in a suction state by the suction shell.

In this state, the yarn suction device filter is lowered by the operation of the robot 2, and at this time, the yarn is held in a suction state without being cut by the suction device filter, and is placed at a position slightly lower than the bottom end of the bobbin 7. , the thread guide arms 5a, 5b are stopped.

The movement of the robot 2 causes it to swing upward.

Yarn guide groove 4a provided at each tip.

4b, the yarn 11 that is being held under suction is surrounded from both sides (this state is shown in FIG. 6).
1 is twisted around the yarn guide grooves 4a and 4b.
(Illustrated in a partial plan view in the figure). Next, robot 2
As a result of the operation, the yarn suction device is moved in the horizontal direction, separated from the bobbin 7, and stopped near the bobbin 7. In this state, the yarn suction A6 is raised by the operation of the robot 2 until the yarn 11, which continues to be suctioned, is substantially parallel to the lower end position of the winding part of the yarn package main body. 2, then by the operation of robot 2? The yarn suction device is moved 9 times around the axis of the bobbin 7 with a radius of rotation R (see Fig. 4), and is lowered at a speed that forms the desired proper tail winding portion. Since the yarn suction device is not pulled out in the reverse direction, rotation and lowering are stopped when the proper tail winding portion 14a (see FIG. 4) is formed.

Next, in this state, the tape sticking means 8 is activated twice, and the tail tape 6 is held at the tip.

It is attached to the lower end of the newly formed proper tail winding portion 14a (this state is shown in FIG. 4).

Next, the yarn cutting tool 9 is moved toward the yarn 11 that has been drawn out from the tail tape 6 and is being sucked by the yarn suction tool 6, and the yarn 11 is cut. The cut threads lose their suction tension and flow from the thread suction tool 3 into a suction port (not shown), where they are captured by a thread separation and collection device (not shown). Next, the bobbin gripping means 10
is activated.

The yarn package in which the proper tail winding portion 14a is formed is as follows:
It is returned to the yarn package storage section 1.

The yarn package is removed from the bobbin gripping means 10. This device 100 starts forming the proper tail winding portion of the secondary yarn package in accordance with the above-described operating sequence.

I have already mentioned this above. Horizontal movement of yarn suction device 3.

Various types of robots 2 are currently known that perform two vertical movements and swing opening/closing movements of the yarn guide arms 5a and 5b according to position detection or time schedules, so a detailed explanation thereof will be omitted here. . The mechanism for holding and releasing the bobbin holding means 10, as well as the means for automatically doing this, are important.

Since this is an elemental means often used in the textile industry, detailed explanation is omitted here. Furthermore, the tail tape 6 itself as well as its automatic application means 8 are also well known in the textile and labeling equipment industries.

The yarn cutting means 9 as well as the cutting mechanism itself as well as its automatic operating mechanism are well known in the textile industry.

Detailed explanation here is omitted.

(F) Effects of the Present Invention Since the present invention has the above-mentioned configuration, it is possible to mechanically correct a large amount of the tail winding portion of a yarn package in which the tail winding portion is formed using a high-speed winder. Although the high-speed winder had been developed, it solved the problem of the overcrowded tail winding section, which had begun to cause serious problems in its practical application.

This has the remarkable effect of making it possible to produce and put into practical use a yarn package with a tail using a high-speed winder. The present invention can also be used to modify the tail winding portion of a tail yarn package wound with a conventional winder.
