Description

Elastic Winding Machine for Elastic Use and Real Thread Conversion Method

The present invention includes a bobbin holder, a touch roller, a traverse device, and a position exchange means of the bobbin holder. When the package is full, the bobbin holder having the empty bobbin and the bobbin holder on the side of the full package are exchanged. The present invention relates to an elastic spin wound machine for converting yarn into a bobbin.

Conventional spinning yarns of this type for elastic use rotate the tread plates with two bobbin holders to replace the bobbin holders, and when the package is full, the yarns are continuously wound by winding the yarns by converting the bobbin holders. Air winders are common. In this spinner, as shown in FIG.2 (c), the tarlet 2 is rotated and stopped so that the ball bobbin Be may come to the intermediate position M beyond the winding position K. FIG. Then, the thread guide (7), which is a thread winding means, is moved to the gongbin (Be) for one week, and the braking is applied to the multi-package package (P) to relax the thread (Y) and the elastic yarn (Ya). Attach to the surface of (Be). The thread Ya is wound on the surface of the gongbinbin Be and is cut off between the gongbobin Be and the all-round package P by the mounting force generated when the yarn Ya on the package P side is wound. The next elastic yarn (Y) is wound from above the elastic yarn (Y) attached to the gongbin (Be) to fix the four ends. After the thread winding guide 7 is returned, as shown in Figs. 2 (d) and (e), the bobbin Be is returned to the winding position K, and the traverse device 4 shifts to the main winding. .

In Fig. 4, the position of the yarn Y wound on the thread guide 7, the wound winding package P, and the bobbin Be is shown. When the seal guide 7 moves in the state of FIG. 2 (c), the thread Y being traversed is a guide groove consisting of two curved portions 10 provided on the guide bar 18 of the seal guide 7. (9) is captured. Then, the thread guide 7 is moved so that the thread Y travels along the outer periphery of the gongbin Be, and a rapid braking is applied to the all-round package P to relax the thread Y, so that the downstream thread is moved upstream. Make sure that the seal is sufficiently in contact with the seal and adhere to the surface of the gongbobin Be. This is because when the yarn Y is wound on the gongbin Be, if the yarn is relaxed and reduced in advance, if the yarn is not sufficiently brought into contact, the yarn elongated during winding will shrink after contact. This is because, if the amount of contact of the yarn is small, the yarn that has been in contact with one another is separated and the yarn conversion fails.

As described above, in this conventional spin-winding machine, since the braking device is applied to the universal package to relax the thread, and the elastic yarn is attached to the surface of the bobbin, the braking device that applies the rapid braking to assist the winding to the bobbin is provided. Needed. In addition, it is possible to wind the rod around which the unnecessary yarn generated at the time of actual conversion is wound on one surface on the surface of the package. In this case, in this case, the conditions of the winding (rod winding), the usual winding, and the mounting force are different, so the physical properties of the yarn are different and must be removed. However, since the elastic yarn is fine and strong in adhesiveness, it is very difficult to find a division (thread end of the winding end portion of the elastic yarn) not found to the extent that it is sucked into the section. For this reason, he did not remove the sack, such as winding the thread of the sack portion (rod wound) and pulling it out of the package. At this time, the package surface was often damaged by nails.

The present invention has been made in view of the problems existing in such a conventional technology. The problem can be provided with an elastic spinning spinner which can be reliably carried out with a simple structure and can easily find the end of the winding end portion of the yarn from the package.

In order to achieve the above object, in the invention according to claim 1, the mounting force caused by peeling off the thread wound on the package from the winding width and winding the thread on the bobbin end of the all-round package having a circumferential speed difference is reduced. The actual conversion means for real conversion is installed in the gongbin.

In the invention according to claim 2, the yarn converting means is configured to serve as a yarn winding means for winding the elastic yarn in the bobbin.

In the invention according to claim 3, in the elastic yarn spinning machine according to claim 2, the thread winding means removes the thread on the downstream side of the gongbinbin after the supply company on the side of the full package is removed from the winding width by the thread conversion means. The time until contacting the yarn on the upstream side of the gongbinbin is set to the time when the bunching is formed at the end of the bag.

Therefore, in the invention according to claim 1, the tension is reduced by peeling the supply yarn from the surface of the package having the high rotational speed to the bobbin end side with the low rotational speed, and the elastic yarn is relaxed by using the decrease in tension. It acts as an aid to the cold.

In the invention according to claim 2, the thread is peeled off from the winding width of the package as the thread converting means, and the peeled thread acts as it is to be wound onto the bobbin as the thread winding means.

In the invention according to claim 3, when the winding is exchanged from the full volume package to the empty bobbin, the thread on the downstream side of the empty bobbin contacts the upstream thread and is placed at the bobbin end of the full volume package before the actual conversion is completed. It acts to secure a time margin for forming the winding.

EMBODIMENT OF THE INVENTION Below, embodiment of this invention is described based on drawing.

In FIG. 1, the basic structure of the spin winder 5 is demonstrated. The spin take-up machine 5 has a structure in which a lifting frame 1 capable of freely lifting up and down the base 8 and a rotatable tarlet 2 serving as a position exchange means of a bobbin holder are provided.

The lifting roller 1 is supported by a touch roller 3 and a traverse device 4, and the touch roller 3 is always in pressure contact with the four layers of the bobbin at a winding position described later. It rotates counterclockwise. Moreover, the traverse guide 6 is provided in the traverse apparatus 4, The traverse guide 6 engages with the yarn Y, and traverses the yarn Y by reciprocating the traverse range, have. The yarn Y is continuously supplied at a predetermined traveling speed from the ejector not shown.

The tarret 2 is driven by a drive source such as an induction motor (not shown) around the rotation shaft 14. Two bobbin holders 15 and 16 are each equipped with a plurality of bobbins inserted therein, one bobbin holder 15 at a winding position K, and the other bobbin holder 16 at a standby position L. FIG. ) In addition, the bobbin denotes the bobbin of the four-layered bobbin, that is, the package P, is referred to as bobbin Bf and gongbinbin (Be) for ease of explanation.

The seal guide 7, which is a thread winding means, is composed of a swinging arm 17 which is supported at a lower portion of the base 8 and a guide bar 18 attached to the tip of the swinging arm 17. The swinging arm 17 is provided at the front end side of the bobbin holder 15, 16, and the guide bar 18 mentioned above is attached to the attachment base side of the bobbin holder 15, 16 from this front end side. I'm speaking with turning. When the gongbin Be, which is the actual conversion position, is at the intermediate position M shown in Fig. 2 (c), the swinging arm 17 is rotated so that the guide bar 18 is placed on the gongbin Be. The rotary shaft 19 of the swinging arm 17 is installed at the position where the (Y) can be wound. The actual conversion position is a middle position (M) between the winding position (K) and the standby position (L), so that the winding angle of the thread (Y) with respect to the gongbinbin (Be) is about 1/3 or more around the perimeter To reduce the amount of rotation of the seal guide 7 and to allow the seal guide 7 to rotate only at a position deviating from the rotation trajectories of the bobbin holders 15 and 16. To simplify the structure.

The swinging arm 17 swings about 180 degrees around the axis 19 by a drive means such as a rotary actuator (not shown), and the seal guide 7 is moved from the standby position of the solid line shown in FIG. Move to the operating position of the dashed line. When the seal guide 7 rotates counterclockwise from the standby position to the operating position, as shown in Fig. 2 (c), the downstream yarn Ya is wound along the outer circumference of the bobbin Be, and the seal guide ( The seal guide 7 is rotated to a position where the guide groove 9 described later in 7) completely contacts the seal Y discharged from the upstream side. For this reason, the yarn Y in the guide groove 9 and the yarn Yb discharged from the upstream side come into contact with each other in the guide groove 9 which is also a member for restricting the movement of the yarn. The yarns Ya and Yb in contact are elastic yarns and the viscous viscous yarns are wound around the yarns Yb by being wound on the yarns Yb, and the yarns are attracted. Cut and cut.

The guide bar 18 is attached to the tip of the swinging arm 17 and has a guide groove 9 into which the thread Y enters, as shown in FIG. Guide groove 9 is composed of a bent portion 10 for guiding the yarn (Y) according to the curve, and the cutout portion 11 for regulating the yarn (Y) guided from the bent portion 10, the bent portion (10) and The part of the groove into which the cutout part 11 joins becomes a little thicker than the thickness of a thread, and the contact of the yarn Ya and the yarn Yb is performed reliably. The position at which the bent portion 10 and the cutout portion 11 are aligned is outside the winding width (traverse range) of the package P, and the seal guide 7 is threaded (Y) (winding) in the guide groove 9. A winding means for the winding starting thread winding the starting portion) to the end of the blank bobbin Be, and the thread for releasing the yarn Y from the four-layer surface of the full winding package P toward the end side of the bobbin Bf. It also serves as a conversion means. For this reason, the number of parts is reduced, the structure of the spin winder is simplified, and the control is simplified.

In the guide groove 9, the thread Ya, which is released from the four-layer package P to the end side of the bobbin Bf, is wound from the fast circumferential speed of the four-layer package P to the late circumferential speed of the bobbin Bf. As a result, mounting force is greatly reduced. At this instant, the mounting force is actively used to rapidly apply a brake to the package P, which has been conventionally performed, to relax the yarn Ya to reliably and sufficiently secure the elastic yarn Ya and the yarn Yb. It is intended to be used as a substitute for assisting the wound around the gongbin (Be) by contact.

Then, the yarn Ya peeled off from the full package package P toward the end side of the bobbin Bf not only decreases the tension momentarily, but also continuously decreases the tension until the yarn is terminated and the thread is cut. This is because the spinneret controls the rotation of the bobbin holder so that the circumferential speed of the all-round package P and the circumferential speed of the empty bobbin Be are the same, so that the circumferential speed of the empty bobbin Be is the bobbin Bf of the all-round package P. It is faster than the speed of). In other words, it is because the gongbin Be acts like a feed roller to reduce the tension of the yarn Ya downstream of the gongbin bin Be.

This work is that the actual conversion is surely performed even after a while after deviating from the full package package P toward the end side of the bobbin Bf. That is, after performing the bunching winding 12 which winds the yarn unsatisfied at the time of thread conversion to the end side of the bobbin Bf reliably and repeatedly in one place, thread yarn Ya and yarn Yb are brought into contact with yarn thread conversion. May be performed. The bunching winding 12 is different from the winding of the rod any number of times in one place on the package surface, and the end (thread tip) of the winding end portion of the winding wound on the package P comes to the end side of the bobbin Bf. It is easy to find the end (thread end), and it is easy to pull out, and even the surface of the package is not damaged even if it is chopped with a nail, and the unnecessary thread generated at the time of thread conversion can be easily removed without damaging the package P.

The drive means of the seal guide 7 and the drive source of the tarlet 2 are configured to control the rotation timing, the speed, and the like by a controller not shown.

Next, the actual conversion method of the above-described spin winder 5 will be described based on FIG. 2. In FIG. 2 (a), when the package P becomes full volume, even if the tarlet 2 is rotated counterclockwise, even if it passes through FIG. 2 (b) which is the actual conversion position of the normal spin winder 5, FIG. It rotates again, and stops rotation of the tart 2 when the gong bin Be reaches | attains FIG.2 (c) which is an intermediate position of the winding position K and the standby position L. FIG. At this time, the elastic yarn Y is pressed against the surface of the gongbin Be, and travels in a state of contacting (adhering) about one third or more of the entire circumference of the gongbin Be. For ease of explanation, the upstream side of the yarn Y is referred to as (Yb), and the downstream side from the cavity (Be) is referred to as (Ya). As the thread Y contacts the gongbin Be, at the same time, the circumferential speed of the gongbin Be is increased by 0 to 50%, and the tension on the Ya side is lowered.

In the winder of the elastic yarn, the traverse of the yarn Y is continued even when the bobbin holder is replaced. When the ball bobbin Be reaches the intermediate position M and the seal guide 7 is rotated counterclockwise, the thread Y being traversed is captured by the guide groove 9. After that, the thread guide 7 is rotated again to move the yarn Ya along the curved portion 10 from the surface of the all-round package P to the end side of the bobbin Bf, and the upstream yarn Yb. The seal guide 7 is rotated until the seal Ya contacts the seal Yb. When the yarn Ya is moved from the surface of the full winding package P toward the end side of the bobbin Bf, the mounting force decreases due to the difference between the peripheral speed of the full winding package P and the peripheral speed of the bobbin Bf. Then, due to the decrease in the mounting force, the yarn Y is relaxed without sudden braking of the bobbin holder 15 on the unidirectional package P side, and the yarn Ya and the yarn Yb in the guide groove 9. ) Is securely and sufficiently in contact with each other, the yarn Ya is reliably wound on the yarn Yb, the yarn Ya is pulled out and cut, and the yarn (the yarn at the portion where the winding starts) Y is published. It is wound around the end of the bin Be, and a bunching winding of the start of winding is formed at the end of the gazette bin Be.

When the yarn Y is wound on the gongbin Be, and the yarn conversion is completed, the yarn guide 7 is returned to its original standby position, and the tarlet 2 is rotated clockwise, so that FIG. ), The bobbin Be is moved to the winding position K, and the bobbin Be is brought into contact with the touch roller 3 to carry out the main winding. At this time, the rotation of the tartlet 2 may be stopped at the position of FIG. 2 (d) to move the package to FIG. 2 (e) with a predetermined diameter.

In the winding method described above, the seal guide 7 moves the yarn Y from the full winding package P to the bobbin Bf by the guide groove 9 to reduce the tension of the yarn transformation, ), The seal guide 7 is rotated until the seal Ya contacts the seal Yb. In other words, the yarn Ya is relaxed using only the decrease in tension when the yarn Y deviates from the surface of the package P toward the end side of the bobbin Bf, thereby reliably securing the yarn Ya to the bobbin Be. In this method, however, the bunching winding 12 (a bunching winding of the winding end portion) is not necessary enough at the end of the bobbin Bf of the package P. For this reason, the method of making the bunching winding 12 reliably is also described below also in the sense that the cutting edges (thread ends) are not loosened at the time of conveyance.

The above-described method is the same until the ball bobbin Be reaches the intermediate position M until the seal guide 7 is rotated counterclockwise, and thus the description thereof is omitted.

When the ball bobbin Be reaches the intermediate position M, the seal guide 7 is rotated counterclockwise. The seal guide 7 moves the seal Ya to the end side of the bobbin Bf by the guide groove 9, and captures and induces the upstream seal Yb. The rotation movement of the seal guide 7 is stopped before the yarn Ya contacts the yarn Yb. When the rotational movement of the seal guide 7 is stopped, the yarn Ya (the yarn at the end of the winding portion) is continuously wound at one place on the bobbin Bf that is out of the winding range, and the bunching winding 12 is formed. Then, after the necessary bunching winding 12 is formed on the bobbin Bf, the seal guide 7 is rotated until the yarn Ya contacts the yarn Yb. The circumferential speed of the bobbin Bf of the package P is later than the running speed of the yarn, and the circumferential speed of the bobbin Be is approximately equal to the running speed of the yarn, and the rotation of the bobbin Bf and the bobbin Be is rotated. Since the speed is different, the thread Ya is in a state in which the tension is reduced, and the thread Ya relaxes without suddenly braking the bobbin holder 15 on the side of the package P. As a result, the thread Ya is relaxed. The yarn Ya and the yarn Yb, which are regulated together, are reliably and sufficiently in contact with each other, and the yarn Ya is reliably wound on the yarn Yb, pulled and cut, and the yarn Y is a gongbin ( Wound on Be).

After the yarn Y is wound around the blank bobbin and the thread conversion is completed, the description of the blank bobbin Be as the winding position K is the same as that described above. As described above, the thread guide 7 also serves as a wound thread winding means for winding the thread of the winding end portion at the end of the full winding bobbin. And this invention may be embodied as follows.

In the embodiment of the present invention, as the method of reliably forming the bunching attenuation 12, the rotational movement of the seal guide 7 is stopped in the middle, but the speed at which the seal guide 7 is rotated is delayed to slow down the yarn (Ya). ) And the yarn Yb are brought into contact with each other, the cutting of the yarn Ya may be delayed, and the bunching attenuation 12 may be reliably formed.

In the present embodiment, the thread guide includes a thread converting means for removing the thread Y from the package P to the bobbin Bf, and a winding means for winding the thread Ya around the bobbin Be at the thread converting position. Although combined with (7), the thread converting means and the thread winding means may be provided separately and controlled respectively. The thread winding means may be used without any thread winding means. That is, due to the instantaneous reduction of the mounting force caused by the transfer of the yarn Ya from the surface of the full package package P to the end side of the bobbin Bf, and the circumferential speed difference between the mann bobbin Bf and the empty bobbin Be By using only the constant tension reduction, it is also possible to configure the downstream yarn Ya to be wound by winding the bobbin Be, and to perform a real conversion.

In this embodiment, the shape of the seal guide 7 is studied to move the yarn Y in the traverse range out of the traverse range. However, the seal guide 7 is restrained within the traverse range as in the prior art. It is possible to make a shape as well as to freely move in parallel with the bobbin holders 15 and 16 so that the thread guide 7 is restrained after the thread Y is restrained once within the traverse range at the time of thread conversion. The seal Y may be peeled off from the package P to the bobbin Bf, and the coil Y may be wound around the bobbin Be there. At this time, the actual conversion means and the actual feeling means may be separate, or only the actual conversion means may be used.

In addition, in the present embodiment, the actual conversion position is performed by moving the gazette bin Be to the intermediate position M between the winding position K and the standby position L, but is not performed at the intermediate position M. You may perform in the state which moved Be to the winding position K. FIG.

As long as it is only the purpose of forming the bunching sound of the winding end, a spin winder which is not provided with the position converting means of the bobbin holder may be used.

Since this invention is comprised as demonstrated above, it exhibits the same effects as the ratio described below.

According to the invention described in claim 1, the difference between the circumferential speed of the package and the circumferential speed of the bobbin of the full winding package is actively used, so that a large brake device for applying acute movement to the full winding package is unnecessary. Therefore, even if a control device is provided, only a small device for finally stopping the acute rotation of the all-round package is good, and it is possible to provide a spin-winder in which the actual conversion is surely performed with a simple structure.

According to the invention as set forth in claim 2, the thread is peeled off from the winding width of the package as the thread converting means, and the peeled thread is wound up to the public bobbin as the winding means until then, thereby reducing the number of parts. The structure of the spin winder is simplified and the control is simplified.

According to the invention as set forth in claim 3, since the winding end portion of the elastic yarn is wound around the end of the bobbin without being on the four layers of the mann bobbin, it is easy to extract the end of the winding end and easily draw it out. In addition, since the unnecessary yarn generated at the time of actual conversion can be reliably wound on the bobbin, the unnecessary yarn can be removed without damaging the package. Therefore, it is possible to provide an elastic spinning spinneret capable of removing the unnecessary yarn generated during the actual conversion without damaging the package.
