[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fly dust cleaning device that removes fly dust that has adhered or accumulated in various places of a textile machine such as a spinning machine.

[0002]

[Prior art]

 In textile machines, especially in the process of producing spun yarn, extremely large amounts of cotton wool are generated. The cotton wool causes deterioration of the environment, deterioration of the function due to adhesion to machines, and the irregular incorporation of cotton wool adversely affects the product. Therefore, in spinning equipment, air is constantly blown to important points to prevent the attachment of fly cotton, but this is merely to move the fly cotton to other parts, and not only the draft part or the spindle bearing part. Adhesion of cotton wool to the etc. is still a big problem. In order to remove this cotton wool, conventionally, workers regularly or irregularly circulate around the machine base to manually clean it, and once a month, the textile machine itself is overhauled. Then a large amount of cotton wool is removed.

[0003]

[Problems to be solved by the device]

 Some spinning machines are large with 1,000 weights on both sides, and the above-mentioned worker's cleaning and overhaul work is extremely burdensome, and the cotton wool must be sufficiently removed depending on the worker's cleaning. Is difficult.

The present invention provides a fly fluff cleaning device that removes fly fluff adhering to each part of a textile machine by an optimal cleaning means, and further contributes to the automation of the fly fluff removal in the textile machine. It is an object.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the fly dust cleaning device of the present invention includes a entanglement rod that entangles fly dust that adheres to a non-rotating portion, a suction pipe that sucks fly dust that rotates with a rotating shaft, and a frame portion. Further, it has a low-pressure air jet pipe for jetting a low-pressure air stream, and a device for recovering the cotton dust blown off by the low-pressure air jet pipe.

[0006]

[Work]

 In the fly dust cleaning device configured as described above, the fly dust adhering to the non-rotating portion is entangled by the entanglement rod, and the fly dust rotating with the rotating shaft is sucked by the suction pipe and deposited on the frame portion. Fly dust is once blown off by the low-pressure air flow ejected from the low-pressure air ejection pipe and then collected.

[0007]

【Example】

 With reference to FIGS. 1 to 6, an example in which a cleaning carriage equipped with the fly dust cleaning device of the present invention is applied to a spinning machine will be described.

The cleaning carriage R travels along the machine base of the spinning machine S in operation and mainly absorbs dust trapped on the entanglement bar 1 for cleaning the fixed shaft, the rotary shaft, or other members. A suction pipe 2 for pulling, a fixed shaft, and a low-pressure air jet pipe 3 that blows out fly dust that has accumulated on parts other than the rotating shaft, etc., for example, a unit consisting of 6 weights shown by the arrow in FIG. The cleaning is performed by stopping each frame. Except for some of these cleaning means, these cleaning means are supported by the bogie so that they do not hit each member or thread of the spinning machine S when the bogie runs, and when the bogie stops for each unit frame. In addition, it is configured to move forward to the spinning machine side.

The cleaning carriage R is positioned when the vehicle is stopped by detecting a pin or the like provided corresponding to each unit frame of the machine frame of the spinning machine S. Further, the cleaning carriage R is provided not only with each spinning machine S but with a roller wheel 4 or the like so that it can be easily moved by being set in any spinning machine S and operated.

The entanglement rod 1 has a tapered nylon tip portion 1a at the tip of a rod having a diameter of about 4 mm, and fine irregularities are formed on the surface of the entanglement rod 1 in order to easily entangle fibers. Has been done. The reason why the tip is made of nylon is to prevent it from being damaged even if the tip comes in contact with a shaft or rubber roller that rotates at high speed.

When the cleaning carriage R stops at each unit frame and removes the fly fluff wrapped around the fixed shaft, the entanglement rod 1 rotates about 200 times per minute, and first, Proceed to a position slightly away from the peripheral surface at one end. Next, while further advancing, the tangling rod tip end portion 1a approaches until the peripheral surface contacts the fixed shaft. Then, while the peripheral surface of the tip part is in contact with the fixed shaft, it moves forward and backward while moving in parallel toward the other end of the fixed shaft, and entangles the cotton wool wound around the fixed shaft. By subjecting the entanglement rod to such movement, the fly fluff is removed over the entire length of the fixed shaft. It is not possible to completely remove even the cotton dust that has adhered to the back side of the fixed shaft by only sucking the suction pipe.

[0012] First, the fixed shafts 5, 6 and 7 that support the top rollers protruding from the side of the pendulum arm that supports the top rollers of the draft part are the locations to be cleaned by the entanglement rod 1. can give. The same applies to the other fixed shafts, but even the cotton fly wound around the rotating portion and not rotating together with the rotating portion is to be cleaned by the entanglement rod 1. Regarding the frame parts other than the draft part, for example, the parts such as the spindle bearing part 8 which is in contact with the rotating shaft but the cotton wool is not rotating are to be cleaned by the entanglement rod 1.

An example in which the entwining rod 1 is applied to cleaning the fixed shafts 5, 6 and 7 for supporting the top rollers of the draft part will be described with reference to FIG.

On the upper part of the cleaning carriage R, there is provided a moving part R ′ which is appropriately moved by a mechanism in a direction along the base of the spinning machine S when the entwining rod 1 performs a cleaning operation. There, a guide rail 9 is provided in a direction orthogonal to the machine frame of the spinning machine S, and a tangling rod installation table 10 is provided along the guide rail 9 so as to be able to move forward and backward. The guide block 11 that guides the guide rail 9 so that it does not come off from the guide rail 9 hangs down from the side of the installation base 10. The upper part of the installation bar 10 is a small motor for rotating the installation bar 1. A frame 13 that supports 12 is provided. This frame 13 is provided with a set of three (18 in total) entanglement bars 1 corresponding to each weight belonging to the unit frame. Further, a member 15 that engages with the ball screw 14 that is rotationally driven by a motor 16 is provided below the entanglement bar installation table 10. The entanglement bar installation table 10 rotates the ball screw 14 by rotating the ball screw 14. With this, the spinning machine S can be moved forward and backward. Further, a portion 9a that is raised from the surroundings is formed at a position near the spinning machine S of the guide rail 9, and when the front wheel 17 of the entanglement rod installation base 10 gets over the portion 9a, the entanglement is performed as described above. The rod 1 moves upward slightly away from the peripheral surfaces of the fixed shafts 5, 6, 7 and then further approaches until the peripheral surface of the tip portion 1a contacts the fixed shafts 5, 6, 7. Further, each entanglement rod 1 is rotated by the power transmitted from the motor 12 via a belt 19 that is stretched between a pulley 18 fixed to the entangled rod 1 and the motor 12. Furthermore, after each entanglement rod 1 moves forward and contacts the fixed shafts 5, 6, 7, the moving part R'moves in the direction along the machine frame of the spinning machine S by a cam or the like (not shown). In the meantime, the entanglement rod installation table 10 repeats forward and backward movements to entangle the cotton wool wound around the fixed shafts 5, 6 and 7.

As shown in FIG. 4, the cotton wool wound around the entanglement rod 1 is removed by two peeling blocks 20 made of hard urethane rubber having a V-shaped concave portion 20a at the center of the opposite ends. This is done by pinching and squeezing the entanglement rod tip portion 1a. That is, the distance around the hole surrounded by the V-shaped concave portions 20a of the two abutting stripping blocks 20 at each end is set to be smaller than the outer diameter of the entanglement rod 1, and the entanglement rod 1 is The center of the hole formed by the V-shaped recess 20a is located at the center of the hole. When removing the wrapped cotton wool, the stripping blocks 20 are brought close to each other to sandwich the entanglement rod 1, and in this state, the entanglement rod 1 is stopped or rotated and retracted. With this arrangement, since the tip portion 1a of the entwining rod 1 is tapered, the fly waste can be easily moved to a position having a smaller diameter and can be easily peeled off. The stripped cotton wool is discharged by the soccer 21 arranged below.

With reference to FIG. 3, an example in which the fly fluff removing device including the stripping block 20 and the sucker 21 is applied at the time of cleaning the draft part will be described.

Each stripping block 20 is supported on the entanglement rod installation table 10 by a link mechanism 22 shown by a dotted line above and below the entanglement rod 1 in between. A cam 23 supported by the entanglement rod installation base 10 and rotated by a rotary solenoid or the like is provided between the two levers 22a urged toward each other at the base of the link mechanism 22. . The stripping blocks 20 are simultaneously approached and separated by the rotation of the cam 23 via the link mechanism 22. The approaching movement of each stripping block 20 is synchronized with the backward movement of the entwining rod 1, as described above.

The suction pipe 2 is made of copper or steel, and the suction force may be stronger if it is brought into direct contact with the rotary shaft around which the cotton wool is wound, but in order to prevent damage to the rotary shaft, The base 2a made of nylon or Delrin is applied to the rotary shaft.

When the cleaning carriage R stops at each unit frame and winds around the rotary shaft to remove the fly dust that is rotating together, the suction pipe 2 uses the mouthpiece 2a of the suction pipe 2 by an appropriate mechanism to surround the rotary shaft. Approach the sides.

First, the drive shafts of the front bottom roller 23 and the back bottom roller 24 of the draft part can be cited as the target parts to be cleaned by the suction pipe 2. On both ends of the bottom roller, which has a large number of lateral grooves, rings with attached cotton wool called fiber rings are formed. When this fiber ring grows, it is trapped by the traversing fiber bundle. This causes thread defects. Traditionally, workers strip the fiber ring with a brush or sickle during operation. Here, the suction pipe 2 is mainly used for stripping the fiber ring. As for the frame parts other than the draft part, those that rotate with the rotating shaft, such as the tin pulley for driving the spindle and its tension pulley, are also to be cleaned by the suction pipe 2.

An example in which the suction pipe 2 is applied to cleaning the back and front rollers 23 and 24 of the draft part will be described with reference to FIG.

Each suction pipe 2 is arranged on the cleaning carriage R so as to be able to move forward and backward. That is, each suction pipe 2 is provided with a member 26 that engages with a ball screw 25 that is rotationally driven by a motor (not shown), and each suction pipe 2 is rotated by this ball screw 25 to produce a spinning machine. You can move forward or backward with respect to S. Incidentally, the suction pipe 2 ₁ for cleaning the bottom back roller 24, for the convenience of the approach path, are formed on the folded, biased counterclockwise by a torsion spring incorporated in the bent tip portion There is. Then, when the suction pipe 2 moves forward, the tip end collides with the protrusion 27 on the spinning machine S side and rotates clockwise against the force of the torsion spring. As a result, the mouthpiece 2a comes into contact with the bottom front roller 24. In addition, the suction pipe 2 ₂ for cleaning the bottom-top roller 23 is, simply move forward, but only carry out the recession.

As for the flies attached to or deposited on the frame parts other than the draft part, which cannot be processed by either the entanglement by the entanglement rod 1 or the suction by the suction pipe 2, the low-pressure air jet pipe 3 A low-pressure air stream is ejected from the blower to blow out the cotton fly, and the fallen cotton dust is sucked and discharged by the suction pipe 28 having a large opening, or is collected by using the entanglement rod 1 and the suction pipe 2. . The blow-off location is above deck 29 if it is above deck 29 of the draft part, and below deck 29 if it is below deck 29 of the draft part.

In a textile machine, such as the spinning machine S, having winding parts on both sides of the machine base, two cleaning carriages having different roles are provided in order to facilitate the collection of the fly waste using the low-pressure air jet. Are prepared and placed on each side of the machine so that they face each other and run simultaneously. For example, one cleaning trolley is equipped with the low-pressure air jet pipe 3, and the other cleaning trolley is equipped with the suction pipe 28 having a large opening to share the roles. By doing so, the efficiency of collecting the cotton wool can be improved.

All the cleaning target locations described above may be cleaned by one cleaning carriage R equipped with all cleaning means. Further, as shown in FIG. 5, one type of cleaning means is mounted for each of the roles such as entanglement by the entanglement rod 1, suction by the suction pipe 2, and blowout by the low-pressure air jet pipe 3. It is also possible to provide dedicated carriages Ra, Rb, Rc, and so that they can be run by connecting several vehicles, or can be run individually and cleaned. In this way, depending on the state, it is not necessary to run each cleaning carriage every time, and some cleaning carriages need to be run once every several times, thus saving energy.
