Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fly dust cleaning carriage that runs along a machine base of a textile machine such as a spinning machine to remove fly dust that has adhered or accumulated at various places.

[0002]

2. Description of the Related Art An extremely large amount of cotton wool is generated in a textile machine, particularly in a process for producing a spun yarn. The cotton wool causes deterioration of the environment, deterioration of the function due to adhesion to machines, and further adversely affects the product by irregularly incorporating the cotton wool. By the way, in a spinning device, air is constantly blown to important points to prevent the attachment of the cotton wool, but this is merely to move the cotton wool to another portion, and to the draft part or the spindle bearing portion. The attachment of fly cotton remains a major problem. In order to remove this cotton wool, conventionally, an operator regularly or irregularly circulates around the machine base and manually cleans it.
Also, once a month, the textile machine itself is overhauled to remove a large amount of cotton wool.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example in which the fly shaving cleaning carriage of the present invention is applied to a spinning machine will be described with reference to FIGS.

The cleaning carriage R travels along the base of the spinning machine S in operation, and mainly sucks the entanglement rod 1 for cleaning the fixed shaft, the cleaning of the rotary shaft, and the dust that adheres to other members. The suction pipe 2, the fixed shaft, and the low-pressure air jet pipe 3 that blows off the fly dust accumulated on a portion other than the fixed shaft and the like are mounted, for example, for each unit frame composed of 6 weights shown by the arrow in FIG. We will stop at and clean it. Except for some of these cleaning means, these cleaning means are supported to the bogie so that they do not hit each member of the spinning machine S, threads, or the like when the bogie runs, and when the unit frame is stopped, the cleaning means is 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 roller wheels 4 etc. 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 to facilitate the entanglement of fibers. Has been done. The reason why the tip portion is made of nylon is to prevent the tip portion from being damaged even if the tip portion comes into contact with a shaft or a rubber roller that is rotating at a high speed.

When the cleaning carriage R stops at each unit frame and removes the fly dust wrapped around the fixed shaft, the entanglement rod 1
First, while rotating about 200 times per minute,
Proceed to a position slightly away from the peripheral surface at one end of the fixed shaft. Next, while further advancing, the tangling rod tip end portion 1a approaches until the peripheral surface comes into contact with the fixed shaft. Subsequently, while the peripheral surface of the tip end portion 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 causing the entanglement rod to perform such movement, the fly fluff over the entire length of the fixed shaft is removed. It should be noted that even the cotton dust adhered to the back side of the fixed shaft cannot be completely removed by only sucking the suction pipe.

[0012] As the target of cleaning by the entanglement rod 1, first, fixed shafts 5, 6 and 7 for supporting the respective top rollers protruding from the sides of the pendulum arm for supporting the respective top rollers of the draft part are mentioned. To be The same applies to the other fixed shafts, but 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. As for the frame parts other than the draft part, for example, the parts such as the spindle bearing portion 8 which is in contact with the rotating shaft but in which the cotton wool is not rotating are to be cleaned by the entwining rod 1.

Referring now to FIG. 2, the entwining rod 1 is fixed shaft 5, 6, 7 for supporting each top roller of the draft part.
An example applied to the cleaning will be described.

On the upper part of the cleaning carriage R, there is provided a moving part R'which is appropriately moved by a mechanism in the direction along the base of the spinning machine S when the entwining bar 1 performs the 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 bar 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 rod 9 so that it does not come off from the guide rail 9 hangs down from the side of the trolley bar installation base 10. At the top, a trolley bar 1 and a small motor 12 for rotating the trolley bar 1 are provided. A supporting frame 13 is provided.
The frame 13 is provided with a set of three (18 in total) entwining rods 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 the motor 16 is provided below the entanglement bar installation table 10.
The rotation of the ball screw 14 causes the spinning machine S
You can move forward and backward. In addition, a portion 9a that is raised from the surroundings is formed at a position of the guide rail 9 close to the spinning machine S, and the portion 9a is entwined around the portion 9a.
As described above, when the front wheel 17 of the vehicle goes over, the entwined rods 1 move upward slightly away from the peripheral surfaces of the fixed shafts 5, 6, 7 and then move further forward so that the peripheral surface of the tip end portion 1a moves. It approaches until it contacts the fixed shafts 5, 6, 7. Also, each entanglement rod 1
Is rotated by transmission of power from the motor 12 via a belt 19 that is stretched between a pulley 18 fixed to them 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 portion 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.

The removal of the cotton wool wrapped around the entanglement rod 1 is shown in FIG.
As shown in FIG.
It is done by sandwiching and squeezing the entwining rod tip portion 1a between two stripping blocks 20 made of hard urethane rubber having 0a. That is, the two stripping blocks 2 abutting each other
The distance around the hole surrounded by the V-shaped recess 20a of 0 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 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. In this way, since the tip portion 1a of the entanglement rod 1 is tapered, the fly cotton can easily move to a position having a smaller diameter,
It can be easily peeled off. The cotton wool stripped off is discharged by the soccer 21 arranged below.

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

Each stripping block 20 is supported on the entanglement bar installation table 10 by a link mechanism 22 shown by dotted lines above and below the entanglement bar 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 from each other via the link mechanism 22 by the rotation of the cam 23.
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 removes the fly dust that is wound around the rotating shaft and is rotating together, the suction pipe 2 uses the mouthpiece 2a of the suction pipe 2 by a proper mechanism to surround the rotating shaft. Approach the sides.

As for the parts to be cleaned by the suction pipe 2, first, the front and bottom parts of the draft part
Each drive shaft of the roller 23 and the back bottom roller 24 can be mentioned. On both ends of the bottom roller, which has a large number of lateral grooves, ring-like fibers called fiber rings are formed on both ends. When the fiber ring grows, it is trapped by the traversing fiber bundle. 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 off the fiber ring. As for the frame parts other than the draft part, those that rotate with the rotating shaft, for example, the tin pulley for driving the spindle and the tension pulley thereof are to be cleaned by the suction pipe 2.

Referring to FIG. 2, the suction pipe 2 is connected to the back and front rollers 23 of the draft part,
An example applied to the cleaning of 24 will be described.

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 driven to rotate by a motor (not shown), and each suction pipe 2 is rotated by this ball screw 25 to produce a spinning machine. Forward against S,
Can retreat. 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 advances, 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, bottom, top roller 2
The suction pipe 2 ₂ for cleaning 3 simply moves forward and backward.

A cotton wool which is attached to or deposited on frame parts other than the draft part, and which is entwined by the entwining rod 1,
For a portion that cannot be processed by suction by any of the suction pipes 2, low-pressure air jets are jetted from the low-pressure air jet pipes 3 to blow off the cotton dust, and the dropped cotton dust is sucked by a suction pipe 28 having a large opening. Suction or discharge, or collect using the entanglement rod 1 and the suction pipe 2. The place to blow off this cotton wool is
Those above Draft Part Deck 29 should be above Deck 29 and Draft Part Deck 2
Those below 9 are below deck 29.

In the textile machine having the winding parts on both sides of the machine base such as the spinning machine S, two cleaning carriages having different roles are provided in order to facilitate the collection of the cotton wool by using the low pressure air jet. Prepare them and place them on each side of the machine so that they will run at the same time. 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.

It is also possible to clean all the cleaning target parts described above by one cleaning carriage R equipped with all cleaning means. In addition, as shown in FIG. 5, dedicated trolleys each having one type of cleaning means are divided into 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. Ra, R
It is also possible to provide b, Rc, and so on and run them in a state in which several vehicles are connected, or run them individually and clean them. In this way, depending on the state, it is not necessary to drive each cleaning carriage every time, and some cleaning carriages need to be run once every several degrees, thus saving energy.

[0026]

Since the present invention is configured as described above, it has the following effects.

That is, it is excluded by the air flow generated from the textile machine.
The cotton wool that cannot be removed can be removed automatically without stopping the textile machine. Therefore, the burden on the worker can be significantly reduced.
