DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning winder for winding a yarn spun from a spinning machine at a high speed, and more particularly to a lifting frame guide.

[0002]

2. Description of the Related Art First, a conventional example of a turret type take-up winder having a turret provided with two bobbin holders is shown in FIG.
And FIG. FIG. 4 is a side view of the spinning winder, and FIG. 5 is a front view of the spinning winder.

The take-up winder 1 comprises a turret 4 rotating about a central axis 3 with respect to a machine body 2, two bobbin holders 5, 6 protruding from the turret 4, and fixed to the back of the turret 4. Induction motors 7 and 8 for rotating and driving the bobbin holders 5 and 6; an elevating frame 10 which rises or descends vertically by being guided by a guide post 9 in the machine main body 2; and a contact pressure supported by the elevating frame 10 Roller 11 and lifting frame 1
And a traverse device 12 supported by the traverse device 12.

The entire weight of the lifting frame 10 supporting the contact pressure roller 11 and the traverse device 12 is supported by a contact pressure cylinder 13 provided between the lifting frame 10 and the machine main body 2. The difference between the lifting force by the cylinder 13 and the contact pressure of the contact pressure roller 11 with respect to the package P is determined. As described above, in the conventional spinning winder, the contact pressure roller 11 that is in rolling contact with the package P is used.
The lifting frame 10 for supporting the cylinder is movable up and down with respect to the machine body 2 by the contact pressure cylinder 13.
Thereby, the contact pressure with the package P is adjusted. That is, the entire lifting frame 10 can be raised in accordance with the winding thickness of the package P wound around the bobbin B while maintaining a predetermined contact pressure. Also, by increasing the air pressure with respect to the contact pressure cylinder 13,
The entire lifting frame 10 can be lifted away from the package.

The outline of the operation of the above-described spinning winder is as follows. In FIG. 5, the bobbin holder 5 has a central shaft 3
At the winding position almost vertically above the bobbin holder 6.
Is at a standby position substantially vertically below the center shaft 3. When the package at the winding position is fully wound, the turret 4 is rotated by 180 °, and the full package P is at the standby position,
The empty bobbin B is switched to the winding position. The yarn Y is wound on the full package P while being in contact with the empty bobbin B, and the yarn Y is transferred from the full package P to the bobbin B by a yarn transfer device (not shown). Next,
The rotation of the bobbin holder 6 at the standby position is stopped, and the full package P is pushed out to a doffing truck (not shown), and the empty bobbin B is inserted into the bobbin holder 6 at the same time. By repeating the above operation, the yarn Y is continuously wound.

In the above-described conventional take-up winder, the bobbin holders 5 and 6 are cantilever-supported rotating bodies, and the bobbin B is wound around a bobbin B to form a package P of a substantial weight.
And a predetermined contact pressure is applied via the contact pressure roller 10. For this reason, the bobbin holder 5,
The bearing 14 for the turret 4, which rotatably supports the turret 6, is arranged as forward as possible of the machine body 2. As a result, the guide column 9 and the contact pressure cylinder 10 are provided on the side of the bearing 14 and shifted from the bobbin holder.

[0007]

However, since the outer diameter of the portion of the bearing 14 of the turret 4 is the largest, the lifting frame 10 is provided across the bearing 14 and the position of the lifting frame 10 becomes higher. However, there is a problem that the machine height of the spinning winder is increased accordingly.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to raise and lower a frame guide capable of reducing the machine height of a spinning winder. It is an object of the present invention to provide a take-up winder provided with:

[0009]

Means for Solving the Problems] take-up winder of the present invention to achieve the above object, a turret two bobbin holders were projected rotatably supported on the machine body via a bearing, said bobbin holder A spinning winder in which an elevating frame having a contact pressure roller that rolls is provided so as to be able to move up and down with respect to the machine main body, wherein the turret has a disk portion with respect to the bearing,
The body, which is smaller in diameter than the disk, and the bobbin holder
The lifting frame is guided up and down freely .
That the guide column, the bobbin holder side position from the bearing
And erected at a position along the trunk . Element, along the barrel, said guide column and parallel, there is arranged side by side contact pressure cylinder for lifting frame.

[0010]

The guide column of the lifting frame is displaced from the turret bearing toward the bobbin holder, so that the lifting frame can avoid the turret bearing having the largest outer diameter. By providing the body portion toward the bearing of the turret to the bobbin holder side, Ru can the body part to a diameter smaller than the disk part is a bearing.
Along with the body , not only a guide column but also a contact pressure cylinder can be arranged.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a main part of a side surface of a spinning winder according to the present invention, FIG. 2 is a cross-sectional view of a main part of a top surface of the spinning winder according to the present invention, and FIG. FIG. Parts having the same functions as those of the spinning winder described with reference to FIGS. 4 and 5 are denoted by the same reference numerals, and description thereof will be omitted.

1 and 2, the turret 4 has a disk portion 21 for the bearing 14, a small-diameter body portion 22, and a mounting portion 23 for the bobbin holders 5 and 6, which are connected in series. The inner ring 24 of the bearing 14 is fitted on the outer periphery of the disk portion 21, and the outer ring 25 of the bearing 14 is attached to the front wall of the machine body 2.

A pedestal 26 and a holding member 27 are provided on the machine body 2.
Is provided, and the guide column 9 is provided upright between the pedestal 26 and the pressing member 27. The position of the guide post 9 is a position next to the bearing 14 and along the body 22, and the connecting shaft 2 from the spindle motors 7, 8.
This is a position where the width is narrowed within a range that does not interfere with the rotation trajectories 8 and 29. That is, the degree of the small diameter of the body 22 is determined by
It suffices that the distance is within the rotation locus of 8, 29 (due to the rotation of the turret 4).

In FIG. 1, a guide column 9 is a main body 2 of the machine.
The elevating frame 10 can be moved up and down while being separated from the front wall of the machine body 2. Therefore, the height of the portion where the elevating frame 10 is installed can be reduced to the extent that it does not interfere with the bobbin holders 5 and 6. In FIG. 2, the guide support 9 and the contact pressure cylinder 13 are arranged side by side so as not to interfere with the rotation locus of the connection shaft 28 of the spindle motor 7 (due to the rotation of the turret 4). The machine width determined by the interval of 9 and the interval of the contact pressure cylinders 13 becomes narrow.

The positions of the bobbin holders 5 and 6 extend forward by the body portion 22 and the load on the bearing 14 increases.
Since there is no obstacle in the outer peripheral part of the bearing, a high-load bearing 14 can be selected and attached. for that reason,
An increase in load on the bearing 14 can be absorbed. Note that 31
Is a rotation shaft of the turret 4, 32 is a pulley with respect to the rotation shaft 31, 33 is a belt, 34 is a pulley, and 35 is a rotation driving motor, which can rotate the turret 4 to a predetermined position. It is a base on which 36 and the machine main body 2 are mounted.

Next, FIG. 3 shows a spinning take-up machine which makes full use of the reduction in the machine height by the mechanism of the lifting frame guide described above.
This will be described below. The contact pressure roller 11 rises only at the beginning of winding (up to a yarn layer thickness of about 20 mm) and rises from the position a1 to the position a2. At this time, the position A of the bobbin holder 5 is at the fixed position. During the initial winding, the full package P is doffed. After doffing, the turret 4 rotates clockwise, the bobbin holder 5 changes from the position A to the position B, and the contact pressure roller 11 also lowers to the position a3. Then, the position of the contact pressure roller 11 remains at the position a3, and the thick winding of the package is released by the clockwise rotation of the turret 4. Finally, the full package P at the b1 position
Is formed. Then, the turret 4 is slightly rotated to bring the full package P to the b2 position where doffing can be performed, and the contact pressure roller 11 is raised to a state in which the thread can be transferred so as to be in contact with the empty bobbin B inserted into the bobbin holder 6. I do. And
A series of operations of transferring the yarn from the full package P to the empty bobbin B and doffing the full package P is repeated to continuously wind the yarn Y.

In order to release the turret 4 in accordance with the winding thickness, the upper and lower limit positions of the contact pressure roller are detected by a sensor, and the turret 4 is intermittently rotated so that the turret 4 falls within a predetermined upper and lower limit position. There is a method of automatically rotating the turret 4 by calculating the winding thickness of the package and a method of automatically rotating the turret 4 with a predetermined function value with the passage of time.

According to the winding method in which the thickened package is released by the rotation of the turret 4, the upper limit height of the contact pressure roller 11 is lowered to the position a2. And, combined with the height of the lifting frame 19 being reduced by the lifting frame guide of the present invention,
The machine height of the spinning winder is reduced. Further, since the trajectory of the package does not protrude sideways, it is possible to narrow the machine width and arrange a number of spinning winders in a predetermined space.

In the above embodiment, a so-called spindle drive type take-up winder in which the bobbin holders 5 and 6 for inserting the bobbin B are directly driven by the spindle motors 7 and 8 has been described. The lifting frame guide of the present invention is also applied to a so-called friction drive type spinning winder that indirectly drives the bobbin B by driving a contact pressure roller that rolls and contacts the bobbin B.

Further, the turret 4 is not limited to the one in which the thickened package is released by the rotation of the turret 4, but the one in which the winding position and the standby position are fixed and rotated every 180 ° as shown in FIG. The lifting frame guide of the invention is applied. Further, one contact pressure cylinder 13 covers most of the entire weight of the elevating frame 10, and the contact pressure as the remaining weight is controlled by slightly changing the air pressure to the contact pressure cylinder 13. In addition to the spinning winder, the contact pressure cylinder 13 may be used as a base cylinder and a small-diameter control contact pressure cylinder may be separately provided in parallel.

[0021]

Oite the take-up winder of the present invention exhibits, guide posts for guiding the lifting frame vertically movably bearings of the turret
Ri for bobbin holders staggered side are erected, it is possible to dispose the outermost diameter it past the larger bearing part moving frame, as possible lifting frame can be provided in the state lowered to the bobbin holder side, The machine height of the spinning winder can be reduced accordingly. In addition, by disposing the guide column and the contact pressure cylinder on the body portion having a smaller diameter than the portion where the bearing of the turret is provided, the machine width of the spinning winder can be reduced.
