[Conventional technology]

An automatic winder is equipped with multiple winding units arranged in parallel. , the equipment arrangement for one of them will be explained with reference to FIG. The winding unit 1 is connected to the bearing pipe 2 and The pipe thread is fixed in position by The thread Y pulled out from 4 is a balloon breaker 6, a tensor 7, and a slab catcher 8. etc. through guides 9 and 10, and is rotated by the traverse drum 13. It is wound up into a package 14. 15 is a thread splicing device, and 16 is a thread splicing device on the package side. A suction mouth 17 guides the yarn to the yarn splicing device 15, and 17 guides the yarn on the pipe yarn side to the yarn splicing device 1. 5, each winding unit has each of the above members, and this A single automatic winder is constructed by arranging multiple spindles of the winding unit 1 in parallel. . By the way, the supply of the pipe yarn 4 to a predetermined position of the winding unit 1 is performed by individually supplying the pipe yarn 4 to a predetermined position. This is done by inserting it into the upright tray 18. Then, the back of the winding unit 1 A pipe supply conveyor 21 is arranged along the front surface, and an empty pipe discharge conveyor 21 is arranged along the front surface. 22 are arranged. Due to the rotation of the disc-shaped feeder 19, the pipe yarn supply conveyor 2 A new pipe thread 4 is taken in from 1, and the empty pipe thread 4' is discharged to the empty pipe thread discharge conveyor 22. put out In addition to the winding position 19a, this disc-shaped feeder 19 has a first standby position 19b. A second standby position 19c is provided, on which two spare pipe threads 4 are placed. ing. That is, each winding unit 1 independently transports, supplies, and winds the pipe yarn 4. , the discharge is to take place.

0003 Next, Fig. 6 shows a conventional example of an automatic winder consisting of multiple spindles in the winding unit mentioned above. This is explained by: The automatic winder 20 has multiple spindles of winding units 1 arranged in parallel. and the main body such as the control device 23 at one end thereof, and circulates along the back side of the winding unit 1. The yarn supply conveyor 21 and the empty tube arranged along the front side of the winding unit 1 It consists of a yarn discharge conveyor 22. Each spindle of the winding unit 1 has a control A device 23 and a sensor 24 for detecting the shape of the pipe thread 4 are installed, and a control device 23 for each weight is installed. is connected to the overall control device 23A via a communication line f. And the control of each weight A command for the winding speed pattern described below is sent from the control device 23 or the overall control device 23A. It will be done.

0004 This winding speed pattern will be explained below. Winding the tube yarn 4 shown in Fig. 4(a) When winding with a unit, if high-speed winding is continued, the unwinding will occur at the end of winding of tube 4. The tension becomes high, and the pipe thread 4 is more likely to break or break. Therefore, the tube At the end of winding thread 4, the winding speed of the winding unit is slowed down to prevent thread breakage and unrolling. Stop. Such a winding speed pattern is controlled by the control device 23 or the overall control device 23A. It is stored and controls the winding speed of each weight. The winding speed pattern is shown in Figure 5(a). As shown, the reduction from high speed v1 to low speed v2 at a determined timing time t1 It can be switched quickly.

[0005] However, the pipe yarn 4 supplied from the ring spinning machine does not necessarily have a fixed shape. No. As shown in Figure 4(b), thread breakage in the ring spinning machine is the cause. An irregularly shaped pipe yarn 5 such as a half-ball is formed. Such a half ball 5 is wound at the winding speed shown in Fig. 5(a). If the pattern is wound, the winding ends at high speed v1. Therefore, The shape of the yarn is detected by the sensor 24 (the amount of winding such as 4 minute winding, half round winding, 6 minute winding, etc.) is detected. This can be determined by detecting the height of the chess part, which is the upper conical surface of the yarn layer. ), as shown in Fig. 5(b), the speed changes from high speed v1 to low speed v2 depending on the winding amount. Different winding speed patterns are controlled to accelerate the timing time t2 for switching to deceleration. A command is given to each weight of the winding unit 1 from the device 23 or the overall control device 23A.

[0006]

[Problem that the idea aims to solve] In the winding unit explained in the conventional technology, all the spindles handle irregularly shaped pipe yarns such as half balls. It is now possible to wind up. Therefore, the winding unit of all spindles is It is necessary to install a sensor to detect the shape of the thread, but this sensor cannot detect unspecified shapes. It is expensive to detect, and if installed in a full weight winding unit, the size of the automatic winder will increase. This has the problem of becoming a major cost increase factor.

[0007] The present invention was made in view of these problems of the conventional technology. , its purpose is to create an irregular pipe winding unit that winds irregular pipe thread with a specific weight. Irregular pipe threads that can be used to wind normal pipe threads when there are few irregular pipe threads. The purpose of the present invention is to provide a winding unit.

[0008]

[Means to solve the problem]

In order to achieve the above object, the irregular tube yarn winding unit of the present invention has a winding position. A specific weight consisting of a winding unit having one or more standby positions in addition to the standby position, A winding speed pattern is installed at a specific weight, and a device is installed to take in irregularly shaped pipe yarns for a specific weight. Or, if the winding speed is changed and the irregular pipe winding unit winds the irregular pipe thread, the A pipe yarn detector is installed at the machine position, and if this detector does not detect the pipe yarn, the This system is equipped with a control device that operates the grinding device for normal pipe threads.

[0009]

[Effect]

Irregular pipe thread is supplied to the irregular pipe thread winding unit as a specific weight via the take-in device. and this specific spindle winds the irregular pipe yarn at the changed winding speed pattern or winding speed. The other weights are used to wind ordinary pipe threads at a constant winding speed pattern. This irregularity When the amount of irregularly-shaped yarn supplied to the yarn winding unit is running low, the The detector detects the problem, and the control device operates the take-in device to supply the normal pipe thread and prevent the defect from occurring. To efficiently operate a tube trimming yarn winding unit.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. Figure 1 shows the irregularly shaped pipe yarn of the present invention. Figure 2 is an overall layout diagram of the automatic winder related to the winding unit. FIG. 3 is a perspective view of main parts.

[0011] In the automatic winder 20 of FIG. 1, two weights 1a and 1b are irregular tubes as specific weights. It is a thread winding unit, and 1 is a normal winding unit as a general weight. specific weight An intake device 30, 31 is provided at each entrance of 1a, 1b. This collection The loading devices 30 and 31 operate when there is no yarn in the second standby position 19c. Built-in mechanical interlock. Also, specifying the pipe yarn supply conveyor 21 A first detector 32 for detecting irregular pipe threads is provided in front of the weight 1a, and this first detector 3 1 activates the capture devices 30, 31. Furthermore, each of the specific weights 1a and 1b A second detector 33 is provided for detecting the presence or absence of a pipe yarn with respect to the first standby position 19b. ing.

0012 In FIG. 2, the intake device 30 is a pivotable plate, and the solenoid 3 At 0a, the operating position is indicated by the two-dot chain line. Further, the arm 30b is in the second standby position 19c. By coming into contact with the tray, it can be removed when there is no yarn in the second standby position 19c. A mechanical interlock is incorporated which activates the entry device 30. 1st detection The vessel 31 has a yarn detection sensor 32a and a yarn layer detection sensor 32b. When the sensors 32a and 32b are ON, it is determined that the yarn is normal, and when the sensor 32a is ON, If the sensor 32b is OFF, it is determined that the yarn is irregular. Further, the second detector 33 It consists of several yarn detection sensors. And, it is the irregular pipe thread of block 35. Detection signal (YES) and no yarn in the first standby position of block 36 (NO) The signal is input to the OR circuit in block 37, and the input device is activated in block 38. Activate.

[0013] Next, the operation of the irregular tube yarn winding unit shown in FIGS. 1 and 2 will be explained below. Figure 1 In this process, the first detector 32 at the entrance of the pipe supply conveyor 21 detects the irregular pipe thread and removes it. The loading devices 30 and 31 are activated. The second standby position 19c of the specific weight 1a is empty. If so, the irregular pipe thread is taken into the specific weight 1a and moved to the second standby position 19c of the specific weight 1a. If there is a pipe thread, the irregular pipe thread is taken into the specific weight 1b. Normally, the occurrence ratio of irregular threads Since the rate is a few percent, if it is an automatic winder with 50 spindles, 1 of 2 specific spindles a and 1b are sufficient. The specific weights 1a and 1b are set at the early timing in Fig. 5(b). The speed pattern is fixed to decelerate at step t2, and the thread at the end of winding the irregular pipe thread is Prevents cuts and balls from collapsing.

[0014] In FIG. 2, the second detector 33 is located at the first standby position of either the specific weight 1a or 1b. When detecting the absence of pipe threads in 19b, the occurrence rate of irregular pipe threads is small. This means that the supply of pipe yarn to specific spindles 1a and 1b is interrupted, and the entire automatic winder is Operation efficiency may decrease. Therefore, there is no pipe yarn at the first standby position 19b. The second detector 33 detects the By operating the device 30 and taking in the normal pipe thread, the specific weights 1a, 1 can be efficiently drive b.

[0015] In the specific weight of the above embodiment, the deceleration is switched from high speed v1 to low speed v2 in Fig. 5. Winding irregular pipe yarn by changing the winding speed pattern to shorten the timing time I explained the case. However, the specific weight winds the irregular pipe yarn at a constant low speed v2. This can also be addressed by changing the winding speed itself.

[0016]

[Effect of the idea]

The irregular pipe yarn winding unit of the present invention is provided with irregular pipe yarns through a take-in device. winding the irregular pipe yarn at the supplied and changed winding speed pattern or winding speed; A detector located at the standby position detects when the amount of irregularly supplied yarn is running low, and the system is controlled. The control device operates the take-up device to supply normal yarn, and the irregular yarn winding unit The winding unit other than the irregular pipe winding unit has been designed to operate efficiently. Winding with a fixed winding speed pattern is sufficient to reduce the overall cost of the automatic winder. Even when there is a small amount of irregular yarn, the operating efficiency of the irregular yarn winding unit can be improved. It never declines.
