Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof cover provided on a spinning winder for winding a yarn spun from a spinning machine at high speed.

[0002]

2. Description of the Related Art First, a conventional example of a turret type spin winding machine equipped with a turret having two bobbin holders projecting from it is shown in FIG.
5 and FIG. FIG. 4 is a side view of the take-up winder, and FIG. 5 is a front view of the take-up winder.

The spinning winder 1 is fixed to the back of the turret 4 and a turret 4 which rotates around a central axis 3 with respect to the machine body 2, two bobbin holders 5 and 6 projecting from the turret 4. The induction motors 7 and 8 for rotating and driving the bobbin holders 5 and 6, the elevating frame 10 which is vertically moved up and down by being guided by the guide columns 9 in the machine body 2, and the contact pressure supported by the elevating frame 10. Roller 11 and lifting frame 1 as well
It mainly comprises a traverse device 12 supported by 0.

An outline of the operation of the above-described spin winding machine is as follows. In FIG. 5, the bobbin holder 5 has a central shaft 3
Of the bobbin holder 6
Is at a standby position substantially below the central axis 3 in the vertical direction. When the package at the winding position is fully wound, the turret 4 turns 180 °, and the fully-wound package P becomes the standby position,
The empty bobbin B is switched to the winding position. The yarn Y comes into a state of being wound up on the full winding package P while being in contact with the empty bobbin B, and the yarn Y is transferred from the full winding 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 is stopped, the full package P is pushed out to a doffing dolly (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 up.

The elevating frame 10 of the above-described conventional take-up winder.
Is the traverse device 12 and the first block 22 that holds the contact roller 11 with the slit 21 through which the yarn Y passes.
And a second block 23 for holding.

[0006]

By the way, the traverse device 12 has a structure in which the cam drum having the reciprocating spiral groove is rotated at a high speed to traverse the shoe engaging with the reciprocating spiral groove. Sliding noise,
Noises such as wind noise of the thread guide attached to the shoe and rotation noise of the bearing of the cam drum are generated. The rotation noise of the bearing of the contact roller 11 is also one of the noise sources.

These noises are generated by the slit 21 of the elevating frame 10.
And propagates forward and downward. Especially, the front side faces the maintenance passage, and there is a problem that the working environment is deteriorated.

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 provide a spinning winder capable of reducing noise generated from the spinning winder. It is intended to provide a soundproof cover.

[0009]

A soundproof cover of a take-up winder according to the present invention that achieves the above object rotatably supports a turret having two bobbin holders projecting from the machine body, and the bobbin holders roll. A soundproof cover provided in a take-up winder having a contact pressure roller and a traverse device for a yarn reaching the pressure contact roller, the elevator frame being capable of moving up and down with respect to the machine body. It is attached to the front surface of the elevating frame and covers at least the pressure roller and the traverse device. In addition to the cover attached to the front surface of the elevating frame, it is preferable that the soundproof cover is configured by a separator that covers the package. Further, it is preferable that the cover attached to the front surface of the elevating frame is capable of expanding and contracting in the vertical width.

[0010]

Most of the noise source is covered by the soundproof cover which is attached to the front surface of the elevating frame and covers at least the pressure contact roller and the traverse device, and the noise from the noise source to the front is absorbed and / or insulated. . If the separator that covers the package in addition to the soundproof cover on the front of the elevating frame has a soundproof function, sound absorption or / and
And the sound insulation characteristics are improved. By using a soundproof cover that can be expanded and contracted in the vertical width, the front surface can be widely covered while securing a space for threading work at the start and a space for pulling out a fully wound package.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are front views of a take-up winder according to the present invention, and FIG. 1 shows a state in which an elevating frame is raised.
Indicates a state in which the elevating frame is lowered. The parts having the same functions as those of the take-up winder described with reference to FIGS. 4 and 5 are designated by the same reference numerals and the description thereof will be omitted.

In FIG. 1, a cover 31 is attached to the front surface of the elevating frame 10. This cover has a soundproof function such as sound insulation and / or sound absorption, and may be a simple iron plate. In the case of an iron plate, it blocks noise from leaking to the front. Preferably, a plate in which a resin is sandwiched between two thin iron plates is used. Since vibration caused by noise is damped by the resin, a sound absorption effect can be expected in addition to the sound insulation effect. A cover in which a sound absorbing material such as a sponge is attached to one side of the iron plate is also preferable.

In FIG. 1, the turret 4 is at the rotation position indicated by the solid line, and the bobbin holder 5 in which the empty bobbin at the beginning of winding is inserted is substantially above the center of rotation 3 in the vertical direction. on the other hand,
The bobbin holder 6 into which the fully wound package P, which is in a stopped state after the yarn transfer, is inserted is substantially below the rotation center 3 in the vertical direction, and the fully wound package P can be doffed. Therefore, the lower side 31a of the cover 31 is the full winding package P.
The cover 3 is on the bottom so that it does not interfere with the removal of the cover 3.
1, the lower side 31a of the cover 31 is located below the cover 31 so that it does not interfere with the removal of the full-wrap package P, and the upper side 31b of the cover 31 is located above the cover roller 31, the traverse device 12 and the upper bobbin holder 5 so as to cover the cover 31. Both sides 31c, 31c have a width substantially equal to that of the machine body 2.

In the illustrated spinning winder, when the doffing of the fully wound package P is completed, the turret 4 rotates clockwise and the bobbin holder 5 moves from the A position to the B position. Then, the winding thickening of the package is released by the clockwise rotation of the turret 4, and the contact roller 11 stays at the position a3. This state is shown in FIG. Lifting frame 1
0 has dropped to a position close to the lower limit position, and the cover 3
The reference numeral 1 covers about 1/3 of the upper side of the full-wrapped package wound up to the b1 state. Then, the full package P is b
When the state 2 is set, the state shown in FIG. 1 is restored.

Therefore, the pressure contact roller 11, the traverse device 12 and the bobbin holder 5 being wound are kept covered by the cover 31 throughout the entire winding process, so that the pressure contact roller 11 and the traverse device 12 are kept. Also, the ratio of noise leaking from the bobbin holder 5 during winding to the maintenance passage side decreases.

Also, the fully wound package P at the b2 position
Stops after swinging the yarn end after passing the yarn,
To prevent the yarn end from getting entangled with the empty bobbin B, the separator 41,
42 are provided. The separator 41 covers the side surface on the left side in the drawing of the fully-wound package P, and is a two-stage structure of a movable partition plate that can move forward and backward with respect to a fixed partition plate, and is rotatably attached at a fulcrum 47. . The separator 41 is normally at the retracted position indicated by the solid line, but at the time of operation, the separator 41 starts to swing while swinging and covers the fully wound package P. The separator 42 covers the side surface on the right side of the full-wrapped package P in the drawing, the second partition plate 36 is obliquely attached to the end of the first partition plate 45, and is pivotally attached at a fulcrum 48. . This separator 42 is normally in the retracted position indicated by the solid line, but when it is activated, it swings as shown by arrow e to cover the fully wound package P. Partition plates 43 to 46 of these separators 41 and 42
When the soundproof function as described above is added to the contact pressure roller 1,
1. The lateral leakage of noise from the traverse device 12 and the bobbin holder 5 during winding is also reduced.

Next, the entire winding process of the spinning winder equipped with the above-mentioned soundproof cover will be described with reference to FIG. The contact roller 11 moves up only from the a1 position to the a2 position only at the beginning of winding the bobbin B inserted into the bobbin holder 5. At this time, the position A of the bobbin holder 5 is in the fixed position. The doffing of the full winding package P is performed during the beginning of the winding. When the doffing is completed, the turret 4 rotates clockwise, the bobbin holder 5 moves from the A position to the B position, and the contact roller 11 also moves to the a position.
Go down to position 3. The position of the contact roller 11 is a
It remains in the 3 position, and the winding thickening of the package is escaped by the clockwise rotation of the turret 4. Finally, the full winding package P at the position b1 is wound. Then, the turret 4 is slightly rotated to bring the fully-wound package P to the b2 position where the doffing can be performed, and the contact pressure roller 11 is raised to be in a thread transferable state in which the contact roller 11 is rolled to the empty bobbin B inserted into the bobbin holder 6. To do. Then, the yarn winding from the full-winding package P to the empty bobbin B is performed, and a series of operations of performing the doffing of the full-winding package P is repeated to wind the continuous yarn Y.

The soundproof cover described above can be applied not only to the type of spinning winder in which the thickening is released by the rotation of the turret, but also to a normal spinning winder as shown in FIG. Lifting frame 1
The cover 32 attached to the front surface of the fixed
3, the movable cover 34 is telescopically expanded and contracted by a cylinder 35. Normally, it is kept extended like a solid line, but in the case of an operation such as thread passing, it can be contracted so as not to disturb the operation.

[0019]

According to the soundproof cover of the spinning winder of the present invention, the ratio of the noise from the noise source leaking to the front surface which is the maintenance passage is reduced, and the working environment is improved. Since the soundproof cover is attached to the front surface of the elevating frame, it can be easily attached. Since the elevating frame rises when the fully-wound package is taken out, the soundproof cover also rises and there is an effect that it does not interfere with the doffing.
