Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traveler exchanging machine for automatically exchanging a traveler inserted in a ring of a ring spinning machine, and more particularly to a traveler exchanging machine provided with a tension measuring device.

[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 the bobbin 2 is inserted, a ring rail 4 that is vertically movable and traversable along the longitudinal direction of the bobbin 2, and a ring 5 fixed to the ring rail 4. A traveler 7, which is attached to the flange 6 of the ring 5 and is free to travel in the circumferential direction,
The balloon control ring 9 and the 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 on 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, runs on the flange 6 of the ring 5, and imparts 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 a friction resistance body for producing a difference in the number of rotations, and at the same time, they are a traveling direction changing mechanism for a twisting action to a winding action.

The traveler 7 is usually a C-shaped metal fitting and is attached to the flange 6 of the ring 5. Since this traveler 7 rotates at high speed on the flange 6 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. Therefore, the present inventor has proposed a traveler exchange 33 that automatically performs traveler exchange (Japanese Patent Application No. 3-326).
960).

By the way, in the ring spinning machine 101, the traveler 7 is attached to the old and new two rings 5 due to a mistake in the traveler replacement, or the traveler 7 is completely attached to the ring 5.
In some cases, the tension of the yarn Y may not be attached, and the tension of the yarn Y may be abnormal. Therefore, it is necessary to check the tension of the yarn Y periodically or after the traveler is replaced.

The tension of the yarn Y in the above-mentioned ring spinning machine has been conventionally measured manually, and periodically or
After exchanging the traveler, a person who possessed a tension measuring device turned around the ring spinning machine and measured the tension for each spindle.

[0006]

However, in the conventional tension measurement, although a tension measuring device is used as a tool, a person rotates around each spindle, and therefore the tension of a ring spinning machine having multiple spindles is to be measured. However, there is a problem that even a skilled person requires a considerable amount of time and a large number of measurement personnel are required.

The present invention has been made in view of the above problems of the prior art, and an object thereof is not only the traveler exchanging means but also a tension measuring device for measuring the tension of the yarn. The present invention is intended to provide a traveler exchange machine which is equipped with the above and automatically performs traveler exchange and tension measurement.

[0008]

A traveler exchanger of the present invention is a traveler exchanger having a traveler exchanging means, which can travel along a ring spinning machine and can be stopped for each bobbin. The tension measuring device capable of advancing or retracting the yarn is provided.

[0009]

When the tension change device is installed in the traveler changer so that it can advance or retract with respect to the ring spinning machine, the tension of the yarn can be automatically measured immediately or periodically after the change of the traveler without manual operation. It will be possible.

It moves up and down at ~ 2 cm). Therefore, the operator adjusts the height while moving the first operation unit 11a up and down to adsorb the wheel 50 to the corner of the ring rail 4. At this time, the height can be easily adjusted by the counterweight 49 in FIG. 3, and an excessive load moment does not act on the ring rail 4. The counterweight 49 shown in FIG. 3 is preferably adjusted so as to apply a downward load to the ring rail 4 to some extent. This is because, in general, the ring rail 4 has a structure that it can be removed by an upward force. Wheel with magnet 50
By doing so, it is only necessary to place the first operating portion 11a at a predetermined position, and the first operating portion 11a can be easily attached to and removed from the ring rail 4. At this time, since the heaviest power source / control carriage 13 is separated from the operation unit 11, the operation is easy.

When replacing the ring, the motor 5
1 causes the wheel 50 to rotate a predetermined amount, and the operation unit 11 can travel for each array pitch P of the rings 5 of the ring rail 4. The traveling of the traveling unit 11 is transmitted to the base 43 via the leaf spring 44 and further to the power supply / control carriage 13 via the link 53, and the entire traveler exchange 33 is traveling. In addition, the presence of the leaf spring 44 allows the operating portion 11 to be slightly moved, and the ring 5 of the operating portion 11 can be moved.
Positioning with respect to is made possible with a small force. That is, the operation section 11 is separated via the leaf springs 44, and the positioning mechanism described below is used to quickly determine the position of the operation section 11. In addition,
A motor for driving the wheels 52 of the power supply control unit 13 may be separately provided, a stress sensor may be attached to the leaf spring 44, and when a certain amount of load is applied to the leaf spring 44, the power supply control unit 13 may be self-propelled and follow up. .

The above-mentioned first operating portion 11a and second operating portion 1
1b and each apparatus provided in the 3rd operation part 11c are demonstrated. As shown in FIG. 4 (a), the first operating portion 11a includes a positioning plate 16 to be described later, and a yarn pulling lever that pulls the yarn to a predetermined position of the ring 5 when the traveler is exchanged to enable the traveler exchange. 21, a traveler removing device 22, a traveler inserting device 23, and a collection box 15 for collecting the old traveler after the replacement are provided. It should be noted that these devices, except for the collection box, are operated in a predetermined order by a common drive source.

The positioning plate 16 provided on the first operating portion 11a is a plate having a semi-circular portion 16a fitted below the ring 5. By pushing the positioning member 16 toward the ring 5, the position of each device provided in the operation unit 11 with respect to the ring 5 is determined. That is, FIG. 4 (b)
As shown in FIG. 2, the ring 5 is a flange 6 on which the traveler 7 is inserted and a mounting flange 5 for the ring rail 4.
a, and the semicircular portion 16a of the positioning member 16 is fitted into the mounting flange 5a.

As shown in FIG. 2, the second operating portion 11b is provided with a yarn holding device 17 and a tension measuring device 24. The amount of yarn stored and held by the hooking member 61 of the yarn holding device 17 is set to an amount commensurate with the delivery for operating the yarn shifting lever 21 and the delivery of the bobbin 2 for moving the traveler 7. Therefore, the rotation speed of the motor that rotates the hooking member 61 is controlled. The yarn holding device 17 also functions as a yarn joining member.

The tension measuring device 24, as shown in FIG.
The operator 14 has the other end rotatable about the shaft 27, the weight 25 provided at one end of the operator 14, the angle detecting piece provided in the second operating portion 11b, and the angle detecting piece. It comprises a comparison means for comparing the detected angle θ detected with a predetermined angle. In the tension measuring device 24 having such a structure, after the traveler 7 is exchanged, the yarn holding device 17 is retracted to the second operating portion 11b, and then the operator 14 is rotated about the shaft 27 at the other end to make the weight. 25 is advanced from the operation portion 11b onto the yarn Y between the snell wire 8 and the front roller 107. Then, when it is detected that the weight 25 comes into contact with the yarn Y, the yarn Y loosens downward due to the weight of the weight 25, and the operator 14 further rotates about the shaft 27. The angle θ at that time, that is, the angle θ when the contact between the yarn Y and the weight 25 is detected, and then the angle θ when the operator 14 further rotates around the shaft 27 is detected by the angle detection piece in the second operation portion 11b. , Digital or analog display is performed, and the detected angle θ is transmitted to the comparison means. Then, the comparing means compares the detected angle θ with a predetermined angle, and if the detected angle is equal to or larger than the predetermined angle, the tension is marked on the weight, or the exchange is notified by displaying the number of the abnormal weight. The predetermined angle is obtained by measuring in advance how much the yarn Y having the desired tension loosens with respect to the weight of a predetermined weight and inputting the angle at that time into the comparison means in the tension measuring device 24. is there.

As the tension measuring device, besides the one shown in FIG. 1, it is possible to use a three-terminal tension measuring device in which a movable terminal is provided between two fixed terminals. In this case, 3
The yarn Y is passed in zigzag between the terminals, and the strain of the terminals measures the tension of the yarn.

A roller 18 (driving means for rotating the bobbin 2 to move the traveler 7) and a knee brake for stopping the rotation of each spindle shaft 1 and slipping are provided on the third operating portion 11c. A lever 19 (rotation stopping means) for operating 1a is provided. by the way,
Some ring spinning machines have a drive motor for each spindle shaft 1. In this case, since a start / stop switch (rotation stop means) is provided in the vicinity of each spindle shaft 1, the third operating portion 11c is also provided with an operating rod for this start / stop switch. Here, the lever 19 stops the rotation of the spindle shaft 1 and enables the traveler 7 to be replaced. Further, the roller 18 is for rotating the bobbin 2 in the stopped state and moving the traveler 7 on the ring 5 to bring it into a predetermined position. A brake device for stopping the rotation of each spindle shaft 1 or the yarn supplying bobbin 2 may be provided in the third operating portion 11c.

Next, the procedure of the traveler exchange by the above-mentioned traveler exchange 33 will be described with reference to FIG. First,
The wheels 50 of the first operating portion 11a rotate and come to a predetermined position with respect to the ring 5. Then, the positioning plate 16 advances and fits into the ring 5, and the entire operation portion 11 is positioned.

Next, the yarn holding device 1 of the second operating portion 11b
7 advances into the yarn path between the snell wire 8 and the front roller 107, and the hooking portion 61 hooks the yarn Y to rotate and stores and holds a predetermined amount of yarn. During this time, the spindle shaft 1 is rotating at high speed. Next, the lever 1 of the third operating portion 11c
9, the knee brake 1a is actuated to stop the rotation of the spindle shaft 1. The belt 3 slips with respect to the spindle shaft 1 on which the brake is applied, and the spindle shafts of the other weights rotate at high speed.

Next, the traveler removing device 22 advances to a predetermined position on the ring 5. Next, when the roller 18 rotates, the yarn Y stored in the yarn holding device 17 is paid out, the yarn is wound, and the traveler 7 moves along the ring 5 (the roller 18 then returns to the avoidance position).
Then, the traveler 7 is locked by the claws of the traveler removing device 22, the traveling of the traveler 7 is stopped at a predetermined position, and the step of stopping the traveler at the predetermined position ends. At this time, the roller 18 is rotated by a predetermined number by a preset control device.

Next, the yarn pulling lever 21 causes the yarn holding device 1 to move.
While further unwinding the yarn stored in 7, the yarn Y is brought close to the ring 5 from above. As a result, the yarn Y is held at a position along the ring 5 that does not hinder the removal and insertion of the traveler 7, and the yarn shifting process ends.

Next, the traveler removing device 22 and the traveler inserting device 23 perform a traveler exchanging process. Then, after the traveler is inserted by the traveler inserting device, the yarn pulling lever 21 returns to the original retracted position, and the slack of the yarn is stored in the yarn holding device 17 again. Then, the hooking member 61 holds the yarn Y and conveys it between the front rollers 107 to perform yarn joining. Simultaneously with this yarn joining, the lever 19 releases the knee brake 1a, the spindle shaft 1 rotates, and normal operation is restored.

In this way, the traveler is exchanged by the traveler exchanging machine 33, and the yarn holding device 17 is moved to the second operating section 11.
After retracting to b, the tension measuring device 24 advances from the second operating portion 11b of the traveler exchanger 33 onto the yarn Y between the snell wire 8 and the front roller 107 to measure the tension of the yarn Y. If there is any abnormality, Mark the weight or display the abnormal weight number on the exchange.

Incidentally, in the above embodiment, for easy understanding, the steps of moving the traveler to a predetermined position, thread pulling step, traveler removing step, and traveler inserting step are described in this order. The steps are usually performed in parallel. In addition, the traveler inserting process and the traveler removing process may be performed in reverse order, and appropriate changes may be made. Although the tension is measured immediately after the traveler is exchanged, the tension may be measured periodically separately from the traveler exchange.

It should be noted that the traveler exchanger of the above-mentioned embodiment is described as being mounted on a traveler exchanger for exchanging the traveler by forcibly stopping the rotation of the bobbin 2 during operation of the ring spinning machine. A tension measuring device may be provided in the traveler exchanging machine for stopping the entire spinning machine and exchanging the traveler.
