Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning winder for continuously forming a filament bundle melt-spun from a spinning head into a winding package.

[0002]

2. Description of the Related Art Various types of this type of spin winding machine are known. Below, a structural example of a turret type spin winding machine will be described with reference to the front view of FIG. 3 and the side view of FIG. explain.
The take-up winder 1 includes a turret disc 4 that rotates around a horizontal axis 3 with respect to a main body frame 2, two bobbin holders 5 and 6 protruding from the turret disc 4, and a turret disc. Induction motors 7 and 8 fixed to the rear surface of 4 to drive the bobbin holders 5 and 6 in rotation, a slide box 10 that is vertically guided up and down by being guided by a column 9 in the body frame 2, and this slide box 10. The touch roller 11 is supported by the slide box 10, and the traverse device 12 is also supported by the slide box 10.
The weight of the entire slide box 10 supporting the touch roller 11 and the traverse device 12 is supported by the contact pressure cylinder 13 provided on the slide box 10 side, and the difference between this weight and the lifting force by the pressure contact body cylinder 13 is The contact pressure of the touch roller 11 is applied to the package P. In addition, B is a bobbin, P is a package wound around the bobbin, Y is a yarn from a spinning machine, 2a
Is a fixed arm portion projecting from the main body frame 2 and provided with an operation panel at its tip.

As described above, in the turret type wind-up winder, the slide box 10 supporting the touch roller 11 rollingly contacting the package P is movable up and down with respect to the main body frame 2 by the contact pressure cylinder 13. The contact pressure cylinder 13 has a structure in which the contact pressure with respect to the package P is adjusted. Then, the slide box 10 moves along with the traverse device 12 as the package becomes thicker.
It rises so as to be pushed up with it, and keeps the contact pressure constant.

Further, the automatic switching of the yarn of the turret type spin winding machine will be described. In FIG. 3, the bobbin holder 5 is in the winding position a, and the bobbin holder 6 is in the standby position b. When the package at the winding position a is fully wound, the turret plate 4 is rotated by 180 ° and the fully wound package P is moved to the standby position a.
The empty bobbin B becomes the winding position b. Then, as shown in FIG. 8, the yarn Y comes into a state of being wound around the bobbin B while being wound around the bobbin B, and the yarn Y is transferred from the full-wrap package P to the bobbin B by a yarn passing device (not shown). Next, the rotation of the bobbin holder 6 at the standby position b is stopped, the full package P is pushed out by a pusher device (not shown) to a doffing dolly (not shown), and at the same time an empty bobbin B is inserted into the bobbin holder 6. By repeating the above operation, the yarn is continuously wound.

By the way, in this type of take-up winder, a traverse device is formed by a traverse device that hangs a yarn on a reciprocating traverse guide. There is also a traverse device, which is called a vane traverse, formed by a traverse device which alternately delivers the yarn to the rotating vanes in a reverse manner.
However, in any of the traverse devices, the speed becomes slow at the yarn turn portion, so that the ear height phenomenon occurs at both ends of the package.

[0006]

Creeping, which cyclically changes the width of the traverse, is known as an effective means for solving this height of ear phenomenon. As a means for realizing this creeping, there is one that periodically changes the width of the reciprocating movement of the traverse guide on the traverse device side, but the structure is complicated and it is difficult to perform creeping by the mechanism of the traverse device itself.

Therefore, it has been proposed to provide two traverse guides which run in opposite directions and to deliver a yarn from the traverse guide at the yarn turn portion to realize an acute turn, but the delivery of the yarn is uncertain. There was a problem that became.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to change the free length in a take-up winder in which high-speed winding is common. The present invention intends to provide a take-up winder to which creeping by means of mechanically can be easily applied.

[0009]

A spinning winder of the present invention that achieves the above object comprises a roller rollingly contacting a package, a bobbin holder, and a traverse device, and the position of either one of the roller and the bobbin holder is used as a reference. The other is positionally movable as the winding increases, and the roller and the package are kept in contact with each other and can be moved toward and away from the traverse device. Specifically, the traverse device is touched. The set of the roller and the bobbin holder is such that the relative position is made variable by using the positionally movable mechanism.

[0010]

In the spinning winder, the position of one of the roller and the bobbin holder can be used as a reference and the other can move as the winding becomes thicker. Therefore, while maintaining contact between the roller and the package wound around the bobbin holder. By using the position-movable mechanism, the set of the roller and the bobbin holder with respect to the traverse device makes the relative position variable by using the position-movable mechanism, and the free length is changed without changing the traverse device.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a view showing a main part of a take-up winder of the present invention and its operation. Since the structure of the take-up winder other than this main part is the same as that described in FIGS. 3 and 4, the same reference numerals are given and the description thereof will be omitted.

FIG. 1A is a state diagram in which the free length is lengthened, FIG. 1B is a state diagram in which the free length is shortened, and FIG. 1A is an example of creeping by changing the free length. FIG.

In FIG. 1A, the slide box 1
A touch roller (roller) 11 is rotatably supported by a shaft 22 at the tip of an arm 21 pivotally supported by a fulcrum 20, and a rod having a nut member 24 at a force point 23 in the middle of the arm 21. 25 are connected. The nut 24 is slidable in the axial direction of the rod 25, but its rotation is restricted and is screwed onto the screw shaft 26. The screw shaft 26 can rotate in a predetermined controlled manner by a pulse motor 27. Therefore, when the pulse motor 27 is controlled, the arm 21 can reciprocate within the predetermined range of the angle α. The addition / separation mechanism of the touch roller 11 to / from the traverse device 12 is mechanically different from the conventional FIGS. 3 and 4.

Traverse device 1 for this touch roller 11
The contact / separation with respect to 2 is a force in the slide box 10, and the contact pressure of the contact pressure cylinder 13 remains the same as in FIG.
As shown in FIGS. 1A and 1B, the position of the touch roller 11 is vertically variable. This touch roller 11
Is variable at the fulcrum 20 with the arm length M and the angle α. For example, when the arm length M is 200 mm and the difference in vertical movement L2-L1 is 2
When it is 0 mm, the amount of displacement of the touch roller 11 in the left-right direction in the drawing is 0.5 mm, and the change in the yarn path between the left and right is out of the question.

Although the state shown in FIG. 1B is normal, the state shown in FIG.
When the arm 21 swings downward toward (a),
The slide frame 10 is pushed up by the amount that the touch roller 11 is lowered. As described above, the slide frame 10 itself includes the contact roller 1 using the contact pressure cylinder 13 shown in FIG.
1 is pressed against the package P, and when the touch roller 11 is lowered by the pneumatic cylinder 24, the slide box 10 is automatically raised accordingly.

When the state shown in FIG. 1A and the state shown in FIG. 1B are changed in a predetermined pattern by program control, the traverse width becomes narrow when the free length is long,
When the free length is long, the traverse width becomes short, and Fig. 1
The creeping as shown in (c) can be realized.

By the way, in the above-described embodiment, the position of the touch roller (roller) 11 of the slide boss 10 can be changed up and down to realize contact / separation with respect to the traverse device 12 and change the free length. It is most suitable for the roller 11 that rotates freely. The slide box 10 moves up and down in synchronization with the top and bottom of the touch roller 11, but instead of the slide box 10, the bobbin holder 5 moves up and down in synchronization, so that the contact pressure state between the touch roller 11 and the package P is maintained. Good. The present invention can be applied not only to the free rotation like the touch roller 11 but also to the positive rotation like a friction roller to rotate the package.

Further, the application of the present invention is not limited to the turret type wind-up winder, but can be applied to various types of wind-up winder. For example, as shown in FIG. 2A, even when the bobbin holder at the winding position and the bobbin holder at the standby position move along the parallelogram, the bobbin holder 5 at the winding position moves in accordance with the vertical movement of the touch roller 11. May move up and down.
Even if the bobbin holder at the winding position and the bobbin holder at the standby position move along the V-shaped passage as shown in FIG. 2A, the bobbin holder at the winding position is moved according to the vertical movement of the touch roller 11. 5 may go up and down.

[0019]

The spinning winder of the present invention makes use of the fact that either the roller or the bobbin holder can be moved in position in correspondence with the winding weight, so that the roller and the package wound on the bobbin holder come into contact with each other. Since the relative position can be changed by moving it toward and away from the traverse device while maintaining the state, the traverse device is left as it is and a simple modification such as adding a roller roller moving mechanism to the original position movable mechanism. Therefore, the free length can be changed, and creeping that can support high-speed winding can be realized with a reliable and simple mechanism.
