Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention ensures that a traveler mounting device for holding a C-type traveler can be surely mounted on a traveler when the traveler is automatically replaced on a ring of a ring spinning machine. The method of installing the Traveler.

[0002]

2. Description of the Related Art First, a ring spinning machine in which a traveler is used will be described with reference to FIG. The ring spinning machine 101 has a twisting mechanism 102 and a drafting mechanism 103. The draft mechanism 103 includes a back roller 104 and an apron 105.
Middle roller 106 having front and front roller 1
07 upper and lower roller pairs are arranged in order from top to bottom, the upper roller of each roller pair is supported by a cradle arm so as to be openable and closable, and the lower roller of each roller pair is driven. The large-diameter sliver S or roving thread S becomes a thread through the draft mechanism 103. This yarn is spun through a twisting mechanism 102 described below.

The twisting mechanism 102 includes a spindle shaft 1 into which a bobbin 2 is inserted, a ring rail 4 which is vertically movable and traversable along the longitudinal direction of the bobbin 2, and a ring fixed to the ring rail 4. 5, a traveler 7 which is inserted into the flange of the ring 5 and can travel in the circumferential direction, a balloon control ring 9, and a snell wire 8 are arranged from bottom to top. The spindle shaft 1 is a belt 3 common to a plurality of weights and normally rotates at a high speed of about 10,000 to 20,000 RPM.

The yarn Y is wound around the bobbin 2 via the snell wire 8, the balloon control ring 9 and the traveler 7. When the bobbin 2 rotates, the traveler 7 is pulled by the yarn and runs on the flange of the ring 5 to impart twist to the yarn. There is a difference in rotation speed between the bobbin 2 and the traveler 7 by an amount corresponding to the length of the yarn sent from above, and the bobbin 2 is wound by this length. That is, the ring 5 and the traveler 7 are frictional resistance bodies for producing a difference in rotation speed, and at the same time, they are a traveling direction changing mechanism for performing twisting action and winding action.

The traveler 7 is a C-shaped metal fitting and is attached to the flange of the ring 5. Since this traveler 7 rotates at high speed on the flange at around 10,000 to 20,000 RPM, it is worn. Therefore, it is necessary to replace the traveler 7 with an old one every 1-2 weeks. The conventional traveler exchange method is manual. That is, the old traveler is removed using an appropriate claw fitting, and a new traveler is inserted. The traveler mounting device may be used as a manual tool for inserting the new traveler. This conventional traveler exchanging method uses a tool but is manually performed, and if all the travelers of the ring spinning machine having a large number of spindles are exchanged, even a skilled person takes a considerable amount of time. Therefore, personnel for this traveler exchange are required.

Therefore, there has been a demand for a traveler exchanging method for automating the traveler exchanging. Such an automatic traveler exchange method is performed in the order of loosening the yarn reaching the traveler, rotating the yarn supplying bobbin to bring the traveler to a predetermined position for traveler exchange, and removing the looseness of the yarn after exchange. If this is sequentially performed for one yarn feeding bobbin, the cycle time becomes long. Therefore, for the three yarn supply bobbins, a preparation process for loosening the yarn reaching the traveler, a work process for exchanging the traveler, and a finishing process for removing the looseness of the yarn after the exchange are simultaneously performed to form the yarn supply bobbins. We proposed a traveler replacement method that shifts one by one and sequentially switches the preparation process, the work process, and the replacement process for one yarn feeding bobbin to shorten the cycle time.

Here, the step of mounting the traveler in the conventional traveler exchange method will be described with reference to FIG.

12A and 12B are views showing the structure and operation of the traveler mounting device 22, wherein FIG. 12A is an overall perspective view and FIG. 12B is an enlarged view of a main part. In FIG. 1A, the traveler mounting device 22 includes an arm 82 into which a large number of the travelers 7 are fitted, a cutout member 83, and a leaf spring 8.
It consists of 4. By moving the cutting member 83 in the direction, one of the travelers 7 is pressed and fed to the tip. As shown in FIG. 7B, the tip 82a of the arm 82 is bent, and the traveler 7 is held in a vertical C-shape with the opening facing sideways. Then, the whole traveler attaching device 22 is moved from the inside of the ring 5 to the outside (direction).
When retracted, the traveler 7 is attached to the ring 5. At the same time, the free traveler 7 is flipped off to the back side in the thickness direction of the paper by the leaf spring 84 of FIG.

Thus, the traveler mounting device 22
Attaches the traveler 7 to the ring 5 simply by advancing to the inner peripheral side of the ring 5 of the ring spinning machine and then retracting to the outer side (direction) of the ring 5.

[0010]

However, the traveler mounting device 22 can carry out the traveler mounting operation with the opening of the traveler 7 facing downward as shown in FIG. 13 once every 100 times. It happens at a certain rate. If the traveler mounting operation is performed with the traveler opening facing downward, there is a problem that the mounting of the traveler 7 on the ring 5 fails. Considering that the traveler exchange may fail due to other reasons while pursuing the improvement of the success rate by the traveler exchange to the limit, this phenomenon that occurs at a rate of about 1 in 100 times, This is a major obstacle to improvement.

The present invention has been made in view of the above problems, and an object thereof is to correct a traveler mounting device so as to hold the traveler in an accurate posture, and then to form a ring of the traveler. Is to provide a traveler mounting method that improves the mounting success rate of.

[0012]

In the traveler mounting method of the present invention for solving the above-mentioned problems, a traveler mounting device for holding a C-shaped traveler is moved from the inner peripheral side to the outer side of the ring of the ring spinning machine to move the traveler. When attaching to the ring, the traveler attaching device retreats to the outer side of the ring after opening to the inner peripheral side, and the opening faces downward. The upper end of the C-type traveler hits the ring and forms a sideways opening, It was designed to advance to the lap side.

[0013]

According to the above means, even when the traveler's opening is facing downward when the traveler mounting device is advanced for the first time, the upper end of the traveler hits the ring and is corrected so that the opening is oriented laterally and the correct posture is maintained. Is held by the traveler mounting device.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a view showing a traveler replacing method of the present invention, and particularly shows a traveler attaching process by a traveler attaching device 22 in a work process described in detail below.

The structure of the traveler mounting device 22 is as shown in FIG. Here, a traveler mounting process by the traveler mounting device 22 will be described.
In FIG. 1A, the traveler mounting device 22 has a ring 5
It shows that it has advanced to the inner circumference side of. At this time, the traveler 7 is not held in the correct posture because the C-shaped opening is directed downward by the tip 82a of the arm 82. Then, as it is, the ring 5 is slightly moved from the inner peripheral side to the outer side (direction) to reach the state shown in FIG. 1B, and the upper end of the traveler 6 hits the ring 7.

FIG. 1B shows a traveler mounting device 2
2 once retracted a little to the outside (direction) of the ring,
The upper end 7b of the traveler 7 is shown in contact with the upper surface of the ring 5. Therefore, it is difficult for the traveler 7 to move in the direction, only the traveler attaching device 22 moves, and the holding position of the traveler 7 is slightly displaced in the arrow direction. Then, the other end 7d of the traveler 7 descends in the direction of the arrow 86 with the one end side 7b as a fulcrum, and the posture of the traveler 7 is corrected so that the opening of the traveler 7 faces sideways.

At this time, the traveler attaching device 22 temporarily retracted to the outer side (direction) of the ring is shown in FIG.
As shown in (c), from the outside of the ring to the inside (arrow 8
5), the lower end 7d of the traveler 7 further descends in the direction of the arrow 86 with the upper end side 7b as a fulcrum, and the opening is in a horizontal posture as shown in FIG. 1D.

In the state shown in FIG. 1 (d), when the traveler mounting device 22 is slightly retracted to the outer side (direction) of the ring, the other end 7d of the traveler 7 is caught by the ring 5 and further retracted. The traveler 7 is attached to the ring 5.

Thus, the traveler mounting device 22
When the traveler moves into and out of the ring 5 twice, the traveler mounting device 22 causes the traveler 7, which is not held in the correct posture in the first advance, to have the correct opening position, which was changed to the horizontal direction by the second advance. It is held in a C shape above and below. As a result, the traveler 7 is securely attached to the ring 5, and the traveler exchange success rate as the whole traveler exchange is improved.

Since a substantially equal force F is applied between the ring rail 4 and the ring rail 4 at any height, the operating unit 11 acts on the ring rail 4 by the attractive force of the magnets 38 and 39 with the self-weight G offset. The wheels 37 have a structure in which an appropriate contact pressure is applied. This is because the stop position of the ring rail 4 that moves vertically between the chess portions 2a of the bobbin 2 and gradually rises as the chess portion 2a of the bobbin 2 is formed is an arbitrary height during the section L. Is. In addition, the operating unit 11

As described above, the wheels 45 traveling on the rails 10 are provided on the carriage 12 for traveling at each pitch P. As shown in FIG. 3, when the motor M5 makes one rotation, the wheels 45 rotate in the direction of arrow E via the links 47, 48, 49 and travel a distance equivalent to the pitch P.

Next, an operation device for traveler exchange that operates at each station of the traveler exchange will be described.

5 and 6 are views showing the structure and operation of the tensor 24 of the first station S1 and the tensor 25 of the second station S2. The left view of FIG. 6 is a top view and the right view of FIG. 6 is D. FIG. In FIG. 5, the tensors 24, 25
Is composed of a comb 71 having three claws 70 and a comb 73 having two claws 72, and the entire tensors 24 and 25 can advance and retract with respect to the yarn Y of the ring spinning machine 101.

The claws 70 and 72 of the comb 71 and the comb 73 protrude from the boards 71a and 73a, respectively, and the comb 73
Is fixed to the shaft 74, and the two claws 72 are the claws 70 of the comb 71.
It is rotatably inserted into the hole 75 provided in the comb 71 so as to be located between the two. Therefore, the pair of combs 71,
The claws 70 and 72 of 73 are meshed with each other by the rotation of the shaft 74, hold the yarn Y in the bent portions 70a and 72a of the claws 70 and 72, and store the yarn Y in the tensor.

Then, the tensor 24 of the second station is provided with a limit switch 76 for detecting the sufficient degree of the meshing inside the board 73a, and the detecting piece 76a is provided inside the board 71a. The degree of this meshing represents the amount of looseness of the yarn Y,
When a sufficient amount of looseness of the yarn Y is obtained, that is, when a sufficient amount of engagement is achieved, the limit switch 76 provided inside the board 73a comes into contact with the detection piece 76a provided inside the board 71a, and the limit switch 76a 76 is turned on, and the feeding of the yarn from the yarn supplying bobbin 2 is stopped.

Next, the operation of the tensors 24 and 25 will be described with reference to FIG. In (a), the tensors 24 and 25 are retracted to the operating unit 11. In (b), when the tensors 24, 25 advance in the direction from the retracted position, the yarn Y causes the yarn Y to move.
Is located between the bent portions 70a and 72a. And the claw 72
Moving around the shaft 74 in the direction, the yarn Y becomes zigzag in the state of (c), the slack is absorbed, and the yarn Y is stored.

The tensor 25 of the first station S1 is for obtaining beforehand the slack of the yarn Y necessary for the traveler replacement, but if the slack amount of the yarn Y is insufficient, the second station S2 will be described below. Since the operation of the yarn pulling lever of the second station is incomplete, the tensioner 24 of the second station S2
Needs to know the slack of the yarn Y, that is, the tension, which is sufficiently accurate, in order to reliably operate the yarn pulling lever. Therefore,
The limit switch 76 and the detection piece 76a shown in FIG. 5 are provided.

The operation of the limit switch 76 is as follows. First, in FIG. 6, the tensor 24 advances in the direction, and the claws 70, 72 mesh in the direction. Next,
The limit switch 76 detects whether the tensor 24 has sufficient slack. If the slack amount of the yarn Y is insufficient,
Since the claws 70 and 72 are not sufficiently meshed with each other, the limit switch 76 is not turned on. In this case, a roller (not shown) is reversed to feed the yarn from the yarn supplying bobbin. When the claws 70, 72 are sufficiently meshed with each other and the limit switch 76 is turned on, the yarn feeding bobbin 2 is reversed to stop the yarn feeding.

Next, a roller (not shown) is normally rotated to wind the yarn around the yarn supplying bobbin so that the traveler travels to a predetermined position. When the traveler stops at a predetermined position, the yarn is stretched, so the limit switch 76 is turned off again and the yarn tension is detected, and it is confirmed that there is no hindrance to the next continuous operation. Although the gate tensor using the pair of combs 71 and 73 has been described as an example of the tensors 24 and 25, an air tensor that absorbs slack by sucking and calling air can also be used. However, gate tensors are preferred because air tensors require an air source.

FIG. 7 is a diagram showing the structure and operation of the traveler positioning device 63 in the preparation process. The traveler positioning device 63 includes a positioning limit switch 60, a positioning lever 61, and a spring 62 provided on the operation unit 11 of the traveler exchange.

The tip of the positioning lever 61 has advanced onto the ring 5 from the operating portion 11 of the traveler exchange described later. The positioning lever 61 is rotatably provided on the operating part 11 of the traveler exchange with a pin 61a as a fulcrum, and a spring 62 is connected to the rear end of the positioning lever 61 so that the front end side crosses the ring 5 at an angle as shown. It is kept. The limit switch 60 for positioning is operated by rotating the tip end of the positioning lever 61 to the left in the drawing.
It is provided at a position where 0a abuts. In this state, the bobbin 2 is normally rotated and the traveler 7 is run in the arrow direction.

In FIG. 7 (b), the traveler 7 moves from the state of FIG. 7 (a) by the normal rotation of the bobbin 2 and contacts the tip end of the positioning lever 61, and the positioning limit switch 60 is turned on. It is a figure where it became. Furthermore,
The bobbin 2 is normally rotated and the traveler 7 is caused to travel in the arrow direction.

In FIG. 7C, the traveler 7 further travels from the state of FIG. 7B by the normal rotation of the bobbin 2, and the contact with the tip end side of the positioning lever 61 is released.
The positioning limit switch 60 that was turned on in
FIG. 6 is a diagram showing a state where the FF state is set. The rotation of the bobbin 2 is stopped at the timing when the positioning limit switch 60 is turned off again, and the traveler 7 stays within the range H.
To stop.

In the preparatory process, if the traveler 7 is present within this range H, the traveler 7 remains at the position where the replacement operating device advances and interferes with the replacement operating device in the subsequent traveler replacement work process. In addition, the traveler 7 is kept in a certain range H in the preparation process.
Since it is moved inward, there is less variation in the time for moving the traveler to a predetermined position where the exchanging work is performed in the next working process, and the start time of the traveler exchanging work in the working process is shortened.

8A and 8B show the structure and operation of the yarn pulling lever 21. FIG. 8A is a top view and FIG. 8B is a sectional view taken along the line JJ of FIG. In FIG. 3A, the yarn pulling lever 21 is composed of a pair of levers 77 and 78, and hook portions 77a and 78a are formed at the tips. The hook portion 77a moves the yarn Y2 downstream of the traveler 7 to the inside of the ring 5, the hook portion 78a moves the yarn Y1 upstream of the traveler 7 to the outside of the ring 5, and the yarn Y obliquely moves on the upper surface of the ring 5. Hold it across.

At this time, since the yarn Y is held so as to cross the ring flange horizontal surface 5a obliquely in the vertical direction, as shown in FIG. 9B, the bottom surface of the traveler attaching device 22 and the yarn Y are The contact surface in the case of abutting against each other becomes point contact, and as shown in FIG. 9B, the yarn rolls on the upper surface of the ring 5 as the traveler attaching device 22 moves,
The traveler 7 is prevented from being attached without the yarn Y hanging.

FIG. 9 is a view showing the structure and operation of the traveler removing device 23. In FIGS. 9 (a) and 9 (b), the left view is a view on arrow I in the right view. The traveler removing device 23 includes a tubular body 80, an arm 79 rotatable in a direction relative to the tubular body 80, and a holding plate 81 attached to the tubular body 80 as a fixing member, as shown in FIG. Consists of. A claw 79a as a detaching member for the traveler 7 is formed at the tip of the arm 79.
When it rotates in the direction, the tip end 81a of the pressing plate 81 and the claw 79a can catch the traveler 7 so that the traveler 7 can be held. Further, the entire tubular body 80 is capable of advancing (advancing in the direction) to the ring 5.

A method of removing the traveler by the traveler removing device 23 having such a structure will be described. Figure 9
In (a), the tip 81 a of the pressing plate 81 and the claw 79.
so that the sandwiching portion of the traveler 7 with a is at the position of the abdomen 7a on the side where the thread of the traveler 7 is hung,
The tubular body 80 is advanced (moved in the direction) to the ring 5. When the bobbin is normally rotated to wind the yarn Y and move the traveler 7, the traveler 7 enters between the pressing plate 81 and the claw 79a and hits the arm 79 to stop. And
The arm 79 is swung in the direction.

In FIG. 9B, the arm 79 is swiveled in the direction, and the traveler 7 is held between the tip 81a of the pressing plate 81 and the claw 79a of the arm 79.
In FIG. 9 (c), the sandwiching portion 7a of the traveler 7 is
The traveler's opening 7c is in the opening direction, and the traveler 7 is removed from the ring 5 by lifting it upward in a direction perpendicular to the upper surface of the ring 5.

In this way, the traveler clamping portion 7a
Is the direction in which the opening 7c of the traveler opens, and when the traveler 7 is removed from the ring 5 by lifting it upward in the direction perpendicular to the upper surface of the ring 5, the yarn Y hooked on the traveler 7 Even if it is lifted vertically upward, it immediately falls vertically downward, and it is no longer said that it will be pulled and cut while being caught by the removed traveler 7.

When the traveler removing device 23 advances to a predetermined position, if the traveler 7 is present at a position where it comes in contact with the traveler removing device 23, the removal of the traveler fails. Therefore, in the preparatory step, FIG.
The traveler 7 is previously moved to a position on the ring suitable for the replacement work in the working process by the method shown in FIG.

FIG. 10 is a top view showing the structure and operation of the yarn slack eliminating device. The slack eliminating device 17 includes an L-shaped lever 5

A limit switch 55 is arranged on the other arm of the lever 57. When the bobbin rotates in the normal direction by the roller 28 of FIG. 3, the loose thread is wound, but when the thread is stretched, the traveler 7 travels along the ring 5. The traveler 7 thrusts into the brush 58, swings the lever 57 counterclockwise, and moves the limit switch 55.
Is activated, it is confirmed that the thread is stretched, and the rotation of the roller is stopped. As described above, if the thread is not stretched after the traveler 7 is replaced, thread breakage occurs at the start of the ring spinning machine.

A traveler exchanging method using a traveler exchanging machine having such a traveler exchanging operation device will be described based on the operation at each station shown in FIGS. 3 and 4. The rollers 26, 27, 28 can contact the side surfaces of the three bobbins 2 and can be independently rotated by a motor. It is assumed that the operation unit 11 carries out the traveler replacement work from left to right in the drawing.

At the first station S1, the positioning plate 16 shown in FIG.
Is positioned. Next, the roller 26 advances to reverse the bobbin 2 and loosen the yarn. This slack in the yarn is absorbed by the tensor 24 shown in FIG. Then, the traveler 7 is moved to the position H on the ring 5 suitable for the replacement work in the second station S2 by the positioning method by the traveler positioning device 63 described in FIG.
Then, after releasing from the tensor 24, the yarn is further loosened so that a loop of the contracted yarn Y can be easily formed above the traveler 7. Then, after the tensor 24 releases the yarn, the operating unit 11 travels to the right side in the drawing by one pitch P and moves to the second station S2.

Next, in the second station S2,
The yarn Y is again zigzag and stored by the tenser 25 shown in FIG. 5, and the yarn Y can be fed or fed with a predetermined yarn tension. At this time, since the loop of the contracted yarn Y exists above the traveler 7, the yarn Y does not come out from the opening of the traveler 7 and the entire loose yarn is stored in the tensor 25. Next, in the arm 79 of the traveler removing device 23 shown in FIG. 9A, the gripping portion of the traveler 7 between the tip 81a of the pressing plate 81 and the claw 79a is the abdomen 7a on the side where the thread of the traveler 7 is hung. It advances to a predetermined position on the ring 5 so that it becomes the position.

Next, when the roller 27 rotates in the forward direction, the yarn Y stored in the tensor 25 is paid out, and the traveler 7 travels along the ring 5 in the clockwise direction as the yarn rotates. Then, the traveler 7 is locked by the claw 79a of the arm 79 of FIG. 9A, and the traveling of the traveler 7 is stopped at a predetermined position. At this time, the roller 27 is rotated by a predetermined number by a preset control device. Next,
The yarn pulling lever 21 shown in FIG. 8 further pulls the yarn stored in the tensor and pulls the yarn Y from above so as to cross the ring 5. As a result, as shown in FIG.
Is held at a position that does not hinder the insertion and removal of the traveler 7. At this time, the yarn Y is held so as to cross the ring flange horizontal surface 5a diagonally in the vertical direction, as shown in FIG.

Next, the arm 79 of the traveler removing device 23 shown in FIG. 9 (b) rotates in the direction to move the claw 79a.
9 and after the tip 81a has taken in the traveler 7.

The disengaged traveler 7 has a claw 79a and a tip 81.
The traveler removing device 2 which is still held by a.
When the Traveler 7 exits, the Traveler 7 collects the Recovery Box 15 in FIG.
Is carried to the top, and the claw 79a and the tip 81a are separated, so that the traveler 7 is dropped into the collection boss 15.

Next, the traveler 7 held by the arm 82 of the traveler attaching device 22 shown in FIG. 1 (a) advances to a predetermined position on the inner peripheral side of the ring 5, and once the whole is slightly outside the ring 5. Retreat to (direction). Then, after slightly advancing to the inside of the ring 5 again, the whole traveler attaching device 22 retracts to the outside (direction) of the ring 5, and the inner end 7d of the traveler 7 is hooked on the ring 5,
The outer end 7b of the traveler 7 is stretched and inserted into the ring 5, and the leaf spring 84 causes the traveler 7 to be blown away in the thickness direction of the paper.

After that, the yarn pulling lever 21 of FIG. 8 returns to the original retracted position, the slack of the yarn is stored again in the tenser 25 of FIG. 5, and then the tenser 25 is released. Next, the released tensor 25 returns to the original retracted position, and the operation unit 11 moves to 1
Drive on the right side of the figure for pitch P and move to the 3rd station.

Next, in the third station, when the roller 28 is rotated in the normal direction and the thread is tensioned by the slack eliminating device 17 of FIG. 10 and the roller 28 is stopped, the slack of the thread is eliminated and the thread returns to its original state. Become.

[0058]

As described above, according to the traveler mounting method of the present invention, the traveler mounting device holding the traveler moves backward and forward with respect to the ring, so that the opening faces sideways even if the opening is a downward traveler. Correcting the correct posture of the traveler eliminates the failure of the traveler exchange due to the poor posture of the traveler and improves the overall success rate of the traveler exchange.

Claims (1)

[Claims] 1. When a traveler attaching device for holding a C-type traveler moves from an inner peripheral side of a ring of a ring spinning machine to an outer side to attach the traveler to the ring, the traveler attaching device advances to the inner peripheral side. Later, the traveler was attached so that the upper end of the C-type traveler, which once retracted to the outside of the ring and faced downward, hits the ring to form a sideways opening and then re-expands to the inner circumference side.
