Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic winder cleaning device for removing accumulated thread waste and cotton wool.

[0002]

2. Description of the Related Art In an automatic winder for forming a bobbin wound with a spinning machine on a package, the unwinding of the yarn from the bobbin and the unwinding of the unwound yarn are wound into the package. When traveling at a high speed, in addition to the generation of cotton wool from yarn, yarn waste is generated at the time of yarn splicing and the like, and these are accumulated in various places of the automatic winder. Such a cotton wool or the like sometimes adheres to the bobbin or the wound yarn to deteriorate the performance of the yarn and deteriorates the working environment of the automatic winder factory.

As a countermeasure against this, conventionally, a suction mouth is arranged at a place where dust is easily accumulated or a place where dust and lint are likely to be generated, and suction air is constantly applied to suck dust. Be done. In addition, a cleaner unit that runs in front of the automatic winders that are installed in a row is provided, and high-pressure air is blown to the places where the fly dust easily accumulates so that the fly dust is blown up and blown from the suction mouth, or it is attached to the cleaner unit. We are taking cleaning measures such as sucking in with a suction mouse.

[0004]

In the above-mentioned conventional cleaning means, when the cotton wool is sucked by the suction mouth which constantly operates in each automatic winder, the stationary air from the outer circumference of the automatic winder toward the inner side is constantly changed. Flow is generated, and some of the cotton dust is constantly sucked, but other cotton dust easily deposits on the front surface of some devices, and it is further necessary to remove such accumulated cotton dust. Cleaning means is required.

In addition, a large suction air flow is required to suck a wide range of cotton dust, and a large equipment is required to form such a large air flow, which requires high equipment cost and is also automatic. When knotting is performed during yarn breakage when the winder is operating, an air flow is applied to unwind the yarn end, but if this strong airflow acts on this air flow, a smooth yarn end release will occur. Since the unwinding was not performed, unraveling could occur, which sometimes adversely affected the performance of the yarn.

Therefore, it is an object of the present invention to provide an automatic winder cleaning device which can reliably remove cotton dust and the like with inexpensive equipment and which does not adversely affect the yarn splicing operation and the like. .

[0007]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a nozzle toward a bobbin supporting floor surface, a bobbin outer circumference, a tensor portion, etc. in an automatic winder for winding a yarn unwound from a bobbin into a package. Is arranged and an air supply device for supplying air to the nozzle is provided to configure an automatic winder cleaning device. With this, it is possible to reliably remove cotton wool, etc. with inexpensive equipment, and This is to prevent the splicing operation from being adversely affected.

[0008]

Since the present invention is constituted as described above, in the automatic winder for winding the yarn unwound from the bobbin into the package, the bobbin supporting floor surface on which the bobbin is likely to be generated and which is likely to be accumulated, Air is intermittently blown from the nozzle toward the outer circumference of the bobbin, the tensor portion, etc. to remove the cotton wool from each portion. At that time, the accumulated flies and the like are surely removed by the turbulent flow due to the intermittent air flow, and by stopping the air supply during the yarn splicing work, the yarn splicing operation is not adversely affected.

[0009]

[Example] On the bobbin supporting floor surface 2 of the automatic winder 1,
The bobbin 3 around which the yarn spun by the spinning machine is wound is supported, and the yarn 4 unwound from the bobbin 3 is a tensor 5,
It passes through the slab catcher 6 and the like, and is wound while being traversed by a package 8 which is rotated by being pressed against a traverse drum 7 which is driven from the outside.

On the other hand, in the rear of the machine base 10, the air duct 1
1 and a distribution duct 13 connected to the air duct 11 by a connecting pipe 12, and one air supply duct 14 is provided in the distribution duct 13 for each unit of the automatic winder.

The air supply duct 14 extends toward the front side of the machine base 14, and the tip end of the inclined end wall 15 has a bobbin top nozzle 16 that opens toward the top of the supported bobbin 3.
And the bobbin 3 is provided on the lower wall 17 of the air supply duct 14.
A bobbin peripheral surface nozzle 18 that is open toward the peripheral surface is provided. Further, on the upper wall 20 of the air supply duct 14, a tensor nozzle 21 opened toward the tenser 5 is provided,
On the side wall 22 of the air supply duct 14, the bobbin supporting floor surface 2
A floor nozzle 23 is provided that is open toward the.

A shutter 24 is provided on the connecting pipe 12 and is opened and closed by an air cylinder 25. Supply of high-pressure air to the air cylinder 25 is controlled by a solenoid valve 26, and the solenoid valve 26 is opened and closed by a signal from a separately provided control device.
Thereby, the supply of high-pressure air from the air duct 11 to the distribution duct 13 is controlled.

In the above apparatus, when cleaning the automatic winder, the electromagnetic valve 26 is sent by a signal from a control device provided separately.
When the cylinder 25 is operated and high pressure air is supplied to the cylinder 25, the shutter 24 opens the connection pipe 12, and the air sent from the separately provided air supply block is supplied from the air duct 11 to the distribution duct 13 via the connection pipe 12. Sending and distributing duct 13
To each air supply duct 14 connected to.

The air thus supplied to the air supply duct 14 is blown from the bobbin peripheral surface nozzle 18 onto the bobbin peripheral surface, and is unwound from the bobbin top nozzle 16 and the bobbin to form a balloon. The yarn is blown and blown away from the tensor nozzle 21 to the yarn in the tensor 5 that is caused by contact with the yarn, and blows off the accumulated fly yarn from the floor surface nozzle 23 onto the bobbin supporting floor surface 2. The cotton dust blown off by each of these nozzles is sucked by the suction mouth of the cleaner unit running on the front surface of each automatic winder unit, or sucked by the suction mouth provided at an appropriate position of the machine base.

Since the solenoid valve 26 is intermittently operated by the control device, the shutter 24 intermittently opens and closes the connecting pipe 12, and therefore each nozzle of the air supply duct 14 is
Air is supplied intermittently. Therefore, it becomes possible to reliably blow off the fly dust and the like accumulated in various places by the turbulent flow generated by the air flow supplied intermittently.

Further, when the yarn splicing device is operated at the time of yarn breakage, especially in the splicer, the twist of the yarn end is returned by the air flow. At that time, the shutter 24 is closed and the air to each nozzle is closed. The supply should be stopped to prevent turbulence in the untwisting air stream and to ensure splicing.

The blowers for supplying the high-pressure air can be arranged arbitrarily, such as one blower for every two spans of the automatic winder.

As described above, since it is possible to reliably blow off the fly dust and the like accumulated by intermittently supplying the air, the air flow blown from the nozzle may be relatively gentle.

[0019]

Since the present invention is constructed and operates as described above, it does not require a large suction air supply equipment as in the prior art, and a small blower and an air supply pipeline are sufficient, so the equipment cost is low, By supplying air intermittently from each nozzle, a turbulent flow can be generated in the air, and the flies and the like that accumulate can be reliably removed. Further, by stopping the supply of the cleaning air to the yarn splicing or the like, it is possible to prevent the yarn splicing from being adversely affected.
