[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a yarn winding device for winding a yarn of a yarn supplying bobbin to form a required winding package. More specifically, the present invention relates to a device for removing fly waste generated from a yarn during winding from a waxing device. And a technology for preventing a failure from occurring in the device.

[0002]

2. Description of the Related Art A yarn winding device used in a spinning factory, etc.
A predetermined package is formed by winding a spun yarn unwound from a yarn supplying bobbin with a winding drum. Usually, a balloon guide, a guide plate, and the like are provided in the yarn path from the yarn supplying bobbin to the winding package. A tension device, a waxing device, a slab catcher, and the like are provided. During the winding process, the yarn comes into contact with the above-mentioned devices and fluff is generated. Fly wool may scatter and adhere to the surroundings, causing damage to various devices, reducing the quality of the package due to mixing and adhering into the package, and increasing the dust concentration in the work environment. Adversely affect the health of the individual.

Conventionally, as one of means for removing fly waste, a cleaning device provided with an exhaust nozzle for blowing air before and after the yarn winding device and an intake nozzle for collecting fly waste dropped on the floor surface. Has been proposed. In this cleaning device, wind is blown from the front and rear to the yarn winding device to blow off the fly waste on the device, and the fly waste falling on the floor is sucked and collected. However, the above-mentioned cleaning device blows air from the front and rear of the device, so that fly waste is easily scattered around, and the recovery rate of the blown fly waste is poor, which may deteriorate the working environment. In addition, the blown fly may float and flow, and may impair another device.

As a solution to the above problems, Japanese Patent Laid-Open Publication No. Hei 10-25059 describes a cleaning mechanism in which the blowing direction and the collecting method of fly waste are improved. This cleaning mechanism is provided with air outlets at upper and lower positions on the front side of the yarn winding device, and air suction holes at an intermediate height position on the back side of the yarn winding device. Air is blown out toward the rear side of the apparatus by blowing air toward the rear side and obliquely upward from the air outlet at the front lower side, and is sucked at the suction port. Since such a cleaning mechanism generates an air flow from the front part to the rear part of the apparatus, it does not scatter fly waste to the front side area of the apparatus which is a passage or a working space, and also collects fly waste. Since the efficiency is good, there is an advantage that it does not adversely affect workers and other devices.

[0005]

As described above, in the middle of the yarn path of the yarn winding device, a waxing device for applying wax to the yarn is provided. Then, in the waxing device, wax residue is generated due to the contact between the yarn and the wax. In addition, fly waste generated during winding of the yarn adheres and accumulates on the waxing device. However, since the conventional cleaning mechanism blows air from outside the waxing device in both the former and the latter, the wax residue generated in the contact portion between the wax and the yarn, or the inside of the casing of the waxing device, is not used. It was difficult to remove the invaded fly wool.

[0006]

In particular, fly waste or wax residue that has entered the casing C or the space around the rotary drive shaft 50 is removed by the air nozzle 2 disposed on the front side of the yarn winding device 1.
It is difficult to blow off the cleaning air ejected from 0 and 21. Therefore, in the present invention, the waxing device 6
In order to reliably remove fly waste and wax residue existing inside the casing C and around the rotary drive shaft 50, a structure is employed in which pressurized cleaning air is blown into the vicinity of the wax W and inside the casing C. As shown in FIGS. 2 and 3, in the waxing device 6 according to the present invention, a cylindrical wax W is disposed outside the casing C, and a motor 40 for rotating the wax W is disposed in the casing C. You. The wall of the casing C is composed of a top plate 30, a front plate 31, an outer plate 36, a partition plate 70, and a bottom plate (not shown), and the rear side is open. The front plate portion 31 is formed by joining a front surface member 31S and a back surface member 31R, and an air passage 32 is formed between the two members 31S and 31R.
A cleaning air supply unit (not shown) is provided on the outer plate portion 36.
A supply port 36a and a supply path 36b that communicate with the
These are in communication with the inlet 32a of the ventilation passage 32 of the front plate portion 31. The ventilation path 32 has a connection port 32b, and supplies pressurized cleaning air into a ventilation path 51 of a rotary drive shaft 50 to be described later through a communication pipe 37.

The rotation drive of the wax W is executed by a motor 40 via a rotation drive shaft 50. In this example, the drive shaft 40a of the motor 40 and the rotary drive shaft 50 are connected to be able to interlock using the couplers 41 and 42. As shown in FIGS. 4 and 5, a ventilation path 51 is formed along the central axis of the rotary drive shaft 50, and ventilation holes 52 and blowing holes 53 and 54 are formed at appropriate positions in a direction perpendicular to the ventilation path 51. Have been. The rotary drive shaft 50 is disposed so as to penetrate the partition plate 70, and the end on which the ventilation hole 52 is formed is disposed at an appropriate interval in the bearing holder 43 attached to the partition plate 70. It is rotatably supported by the bearings 44 and 45. The bearing holder 43
Between the two bearings 44 and 45 in the rotary drive shaft 5
Spacer 38 having an opening communicating with vent hole 52
The bearing holder 43 is connected to a communication pipe 37 that communicates with the ventilation path 32 of the casing front plate 31. A portion of the rotary drive shaft 50 that protrudes outside the partition plate portion 70 is provided with an inner cap 46 that rotates integrally with the partition plate portion 70 and an outer cap 48 that is externally rotatably fitted via a cylindrical slider 58. Have been. A guide washer 59 is rotatably fitted to the distal end, and a support shaft 55 for holding the wax W is connected to the end via a square shaft 71. The inner cap 46 and the outer cap 48 are held by a built-in spring 49 so as not to directly contact with each other. . A ventilation gap 60 is also formed between the other outlet hole 54 and the slider 58. In order to form the ventilation gaps 47 and 60 communicating with the blowout holes 53 and 54, in this example, the outer diameter of the portion 50a of the rotary drive shaft 50 sandwiched between the blowout holes 53 and 54 is set large. The slider 58 externally fitted here is configured so as not to close the blowout holes 53 and 54.

A support shaft 55 is inserted into the central opening of the cylindrical wax W, and the outer cap 48 and the stopper 57 attached to the partition plate 70 are in contact with one end surface thereof. A wax holding plate 56 is mounted on the other end surface, and the surface of the wax holding plate 56 is pressed by a wax holding arm 61. Therefore, the wax W is applied to the outer cap 4 pressing one end face by the urging force of the spring 49.

A lower thread guide 63 and an upper thread guide 64 are provided in order to stabilize the yarn path Y at the upper and lower positions (see FIG. 2).

Waxing device 6 constructed as described above
Applies a wax to the yarn Y traveling between the wax W and the outer cap 48 in the yarn winding step. At this time, by driving the motor 40, the rotary drive shaft 50 is rotated through the couplers 41 and 42. As the rotary drive shaft 50 rotates, the inner cap 46 integrally attached thereto rotates. The rotation of the inner cap 46 is transmitted to the outer cap 48 through a spring 49 by a frictional force. Further, when the rotation drive shaft 50 rotates, the square shaft portion 71 screwed to the rotation rotates, and the rotation force is transmitted to the wax W via the wax support shaft 55 and the wax holding plate 56 to rotate the wax W. .

In the waxing device 6, a wax residue generated by waxing performed by sandwiching the yarn Y between the wax W and the outer cap 48, and a wind generated during the yarn winding process and attached to and deposited on the waxing device 6. The removal of cotton is performed as follows. When cleaning air pressurized from appropriate supply means (not shown) is sent to a supply port 36a provided in the outer plate portion 36 of the casing C, a part of the cleaning air is supplied to the air passage 32 of the front plate portion 31 and It is fed into the bearing holder 43 through the communication pipe 37, and further flows into the ventilation passage 51 in the rotary drive shaft 50 from the ventilation hole 52 via the spacer 38 having an opening. The cleaning air that has flowed into the passage 51 flows out of the air outlet 53, and the ventilation gap 4 between the inner cap 46 and the outer cap 48.
It squirts out through 7. The cleaning air spouted from the ventilation gap 47 prevents the fly waste from coming into contact with the rotary drive shaft 50, which easily winds the fly waste to rotate. At the time of thread changing, the wax moving rod 62 is operated to provide a gap between the wax W and the outer cap 48 as shown in FIG. At this time, the cleaning air is blown out from the blowing hole 54 on the tip side of the rotary drive shaft 50 to the ventilation gap 60, thereby removing wax residue, fly waste, and the like present on the contact surface between the wax W and the outer cap 48. be able to.

The remainder of the cleaning air sent from the supply port 36a of the casing outer plate portion 36 is blown out from blowout holes 33, 34, 35 formed in the front plate portion 31. In this example, as shown in FIG. 7, a groove communicating with the inflow port 32 a is formed in the back surface member 31 </ b> R of the front plate portion 31, and the surface member 31 </ b> S is joined so that the groove becomes the air passage 32. It is. The cleaning air is blown into the casing C from 33 out of the blow holes communicating with the ventilation path 32. Since the rear side of the casing C is open, the fly waste that has entered the casing C can be blown out and removed. The blowout hole 34 is shown in FIG.
As shown in (B), pressurized air is set to be injected to the rotary drive shaft 50 between the outer surface of the partition plate portion 70 and the inner cap 46, and the fly fly attached to the rotary drive shaft 50 is Blow off to the side and remove. The blow holes 35 are formed at appropriate intervals in the vertical direction, and are set so as to blow cleaning air in an oblique direction as shown in FIG. This is because the cleaning air is jetted toward the upper and lower thread guides 63 and 64 (see FIG. 2) which easily generate fly waste.
This is because the fly waste is blown off to the rear side and removed.

In this way, the waxing device 6 is set so that the cleaning air is blown out from the blowout holes 33, 34, 35 of the front plate 31, which is a part of the wall of the casing C, to the rear side. Therefore, there is no possibility of adversely affecting the worker. The fly waste and the wax residue blown from the waxing device 6 are captured by the circulating airflow formed by the air nozzles 20 and 21 provided in the cleaning mechanism, and are sucked into the suction duct 14 and removed.

It is to be noted that, in order to easily fly the fly waste to the rear side and to make it difficult for fly waste to adhere and accumulate.
The waxing device 6 preferably has a structure with as few irregularities as possible. For this purpose, the outer wall surface and the inner wall surface of the casing C are preferably flat surfaces. In addition, since the cleaning gas ventilation path is provided in the wall of the casing C, it is not necessary to separately provide a pipe for transmitting the cleaning gas. Providing the piping increases the number of obstacles to the accumulation location of the fly waste and the flow of air. However, in this example, the above-mentioned problem is solved by making the wall portion of the casing C a ventilation path for the cleaning gas, and the waxing device 6 that does not easily accumulate and attach fly waste or the like is provided.

Incidentally, the embodiment of the waxing apparatus according to the present invention is not limited to the above-described one. For example, an appropriate inert gas such as nitrogen gas or the like may be used as a cleaning gas for blowing off fly waste or wax residue. In the illustrated example, the cleaning gas outlets are provided in both the rotary drive shaft and the casing front plate portion. However, depending on the case, only one of them has no problem. Further, it is not impeded that the supply path of the cleaning gas is separately provided for the rotary drive shaft and the casing front plate. Further, the forming position and the number of the forming holes of the cleaning gas are set at appropriate positions according to the specific structure of the waxing device. In addition, the present invention can be appropriately changed according to the situation of implementation.

[0023]

In the waxing device according to the first aspect of the present invention, since the air path for cleaning gas is formed on the rotary drive shaft for rotating the wax, the contact portion between the wax and the yarn where fluff is generated or in the vicinity thereof. , The cleaning gas can be directly ejected. Therefore, removal of fly waste and wax residue is ensured.

According to the waxing device of the second aspect,
Since the casing in the rear side area is omitted or an opening is formed in the area, and the cleaning gas is blown out from the near side of the casing toward the rear side, the fly cotton is directed to the front side of the yarn winding device. Scattering is prevented, and there is no risk of having an adverse effect on workers.

According to the waxing device of the third aspect,
Since the ventilation path communicating with the supply means of the cleaning gas and the air outlet communicating therewith are formed on the wall of the casing, the piping structure for supplying the cleaning gas to the air outlet can be simplified. Therefore, it is possible to prevent the shape of the waxing device from being complicated, and it is possible to make it difficult to deposit fly waste and the like.
