【Example】

 With reference to FIGS. 1 to 6, an example in which the cleaning cart equipped with the fly fluff removing entanglement rod of the present invention is applied to a spinning machine will be described.

The cleaning carriage R travels along the base of the spinning machine S in operation, and mainly absorbs the cotton dust adhering to the entanglement rod 1 for cleaning the fixed shaft, the cleaning of the rotary shaft, and other members. A suction pipe 2 for pulling, a fixed shaft, and a low-pressure air jet pipe 3 that blows off fly dust accumulated on parts other than the rotating shaft, etc. are mounted, for example, a unit consisting of 6 weights shown by arrows in FIG. The cleaning is performed by stopping each frame. Except for some of these cleaning means, these cleaning means are supported so that they do not collide with the members of the spinning frame S, threads, etc. during traveling of the bogie, and are supported so that they can move forward and backward. 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 the roller wheels 4 and 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 thereof in order to easily entangle fibers. Has been done. The reason why the tip is made of nylon is to prevent damage to the shaft and rubber roller that are rotating at high speed even if the tip comes into contact with them.

When the cleaning carriage R stops at each unit frame and removes the fly dust wrapped around the fixed shaft, the entwining 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 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 wrapped around the fixed shaft. By subjecting the entanglement rod to such movement, the fly fluff over the entire length of the fixed shaft is removed. It is not possible to completely remove even the cotton dust that has adhered to the back side of the fixed shaft by just sucking the suction pipe.

As the target of cleaning by the entanglement rod 1, first, fixed shafts 5, 6, 7 supporting each top roller protruding from a side portion of a pendulum arm supporting each top roller of the draft part are provided. can give. The same applies to the other fixed shafts, but the cotton fly wound around the rotating part and not rotating with the rotating part 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 8 which are 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 rollers 5, 6, 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. A guide rail 9 is provided there in a direction orthogonal to the machine frame of the spinning machine S, and a entanglement rod installation table 10 is provided along the guide rail 9 so as to be able to move forward and backward. A guide block 11 that guides the guide rail 9 so that it does not disengage from the guide rail 9 hangs down from the side of the installation base 10. A small motor for rotating the engagement rod 1 and the engagement rod 1 is provided at the top. 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 rod installation base 10. The entanglement rod installation base 10 rotates 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, as described above, each entanglement is performed. The rod 1 advances slightly away from the peripheral surfaces of the fixed shafts 5, 6 and 7 and then further approaches until the peripheral surface of the tip end portion 1a contacts the fixed shafts 5, 6 and 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 comes into contact with 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 bar installation base 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 stripping blocks 20 made of hard urethane rubber having a V-shaped recess 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 It is arranged so that its center is located at the center position of the hole formed by this V-shaped recess 20a. When the wrapped cotton wool is removed, 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. By doing so, 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 flakes that have been stripped off are 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 peeling 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 the suction pipe 2 is brought into direct contact with the rotating shaft around which the cotton wool is wound, but in order to prevent damage to the rotating 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 and removes 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, ring-shaped fibers, called fiber rings, are formed on both ends. When this fiber ring grows, it is trapped by the traversing fiber bundle. Is caused, which causes yarn 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 frame parts other than the draft part, those that rotate with the rotary shaft, such as the tin pulley for driving the spindle and the tension pulley thereof, are also targets for cleaning 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.

The low-pressure air jet pipe 3 is a part of the cotton wool that adheres to or accumulates on frame parts other than the draft part and cannot be processed by either the entanglement with the entanglement rod 1 or the suction with the suction pipe 2. A low-pressure air stream is jetted 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 place where the fly dust is blown off is above the deck 29 if it is above the draft part deck 29, and below the deck 29 if it is below the draft part deck 29.

In a textile machine, such as the spinning machine S, which has winding parts on both sides of the machine base, two cleaning carts having different roles are provided to facilitate the collection of the fly waste using the low-pressure air jet. Are prepared, and they are placed facing each other on each side of the machine base so that they can 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 this, it is possible to improve the efficiency of collecting the cotton wool.

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 kind 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 in a state in which several vehicles are connected or individually run for cleaning. In this way, depending on the state, it may not be necessary to drive each cleaning carriage every time, and some cleaning carriages need to be run only once every several degrees, thus saving energy.
