[0002] During the textile process of a ring spinning machine, roving needs to be drawn into fine yarn, and the fine yarn is twisted and wound by a ring and traveler assembly. During the drawing process, broken yarn often occurs. If the occurrence of broken yarn cannot be detected in time, a large amount of spinning raw materials will be wasted.

[0003] During the spinning process, the traveler rotates around the ring driven by the yarn. When the yarn breaks, the traveler will stop moving. By detecting the position change of the traveler, it is possible to accurately and quickly determine whether a broken yarn has occurred. In the prior art, generally, a photoelectric sensor is separately arranged at the position of each ring to detect the position change of the traveler at that position. Due to the high price cost of the photoelectric sensor and the easy occurrence of some damages in the use environment, the use cost is relatively high, affecting the economic benefits of the enterprise.

Specific embodiments

[0020] The following combines with the attached drawings to illustrate the specific embodiments of the present utility model.

[0021] As Figure 1 shown, an inspection type ring spinning broken yarn monitoring device includes a long strip-shaped ring rail 1, and a plurality of mounting holes for passing spinning spindles 4 are arranged on the ring rail 1, and one spinning spindle 4 is arranged in each mounting hole. A plurality of rings 2 are sleeved on each spinning spindle 4, and travellers 3 are sleeved on the rings 2, and the travellers 3 can move along the circumferential direction of the rings 2 under the dragging of the yarn.

[0022] As Figure 2 and Figure 3 shown, a linear driving mechanism is arranged on one side of the ring rail 1, and the moving end of the linear driving mechanism is connected to the monitoring module through a support bracket 7. The monitoring module is at the same height as the traveller 3, and the monitoring module can monitor the position change of the traveller 3 to judge whether a broken yarn occurs. During operation, the linear driving mechanism drives the monitoring module to linearly inspect back and forth along the distribution direction of the spinning spindles 4 to realize broken yarn monitoring at multiple positions.

[0023] As Figure 1 and Figure 2 shown, the linear driving mechanism includes a servo linear slide 6. The servo linear slide 6 is fixed on the slide mounting bracket 5, and the slide mounting bracket 5 is detachably connected to the side of the ring rail 1 through a connecting piece.

[0024] As Figure 4 and Figure 5As shown in the figure, the monitoring module includes a monitoring box 12. Inside the monitoring box 12, a PLC controller 18, a light-emitting diode 19, and a photosensitive triode 20 are provided. The light-emitting diode 19 and the photosensitive triode 20 are electrically connected to the PLC controller 18 respectively. When the monitoring module is at the yarn break monitoring position, the light emitted by the light-emitting diode 19 is reflected by the traveller 3 at this position, and the reflected light is received by the photosensitive triode 20, indicating that the traveller is at this position. Then, the photosensitive triode 20 transmits the signal to the PLC controller 18.

[0025] As Figure 4 and Figure 5 shown in the figure, an opening is provided on one side of the monitoring box 12. The light-emitting diode 19 and the photosensitive triode 20 face the opening of the monitoring box 12. The detection light emitted by the light-emitting diode 19 passes through the opening and shines on the traveller 3, and is reflected back to the photosensitive triode 20 in the monitoring box 12 through the opening. A cover plate 21 is provided at the opening position. The cover plate 21 can cover the opening to achieve the closure of the opening and prevent sundries from entering the monitoring box 12. One side of the cover plate 21 is connected to a rotating shaft 22. Both ends of the rotating shaft 22 are rotatably connected to the monitoring box 12 through bearings. One end of the rotating shaft 22 is connected to the driving end of a rotating shaft motor 23. The rotating shaft motor 23 is fixed on the monitoring box 12. When not working, the staff controls the cover plate 21 to cover the opening through the rotating shaft motor 23 to achieve the closure of the opening and prevent sundries from entering the monitoring box 12.

[0026] As Figure 2 shown in the figure, when the monitoring module conducts yarn break monitoring, two traveller monitoring positions are set on each ring 2. The two traveller monitoring positions on each ring 2 are the primary detection position A and the secondary detection position B respectively. The primary detection position A and the secondary detection position B are located at the front end and the rear end of the ring 2 respectively. When the traveller 3 is at the primary detection position A and the secondary detection position B, the monitoring light can irradiate the traveller 3 and be reflected. When the traveller 3 is not at the primary detection position A and the secondary detection position B, the monitoring light cannot irradiate the traveller 3.

[0027] The monitoring module conducts a primary monitoring at the primary detection position A and the secondary detection position B respectively. When the presence of the traveller 3 can be detected at both the primary detection position A and the secondary detection position B, it indicates that during the process of the monitoring module from the primary detection position A to the secondary detection position B, the position of the traveller 3 has changed, thus determining that no yarn break has occurred. When a yarn break occurs, it is possible that the traveller 3 stays at the primary detection position A and the secondary detection position B. At this time, the monitoring module can still detect the traveller 3, which will produce an incorrect monitoring result. The purpose of selecting two traveller monitoring positions on each ring 2 is to avoid the generation of such incorrect results.

[0028] As Figure 1 , Figure 2 and Figure 3As shown, on one side of the support bracket 7 facing the ring rail 1, a switch touch member 8 is connected. On one side of the ring rail 1 facing the support bracket 7, a plurality of travel switches 9 are provided. The plurality of travel switches 9 are arranged in one-to-one correspondence with a plurality of traveller detection positions. The plurality of travel switches 9 are fixed on the side of the ring rail 1 and are located on the movement trajectory of the switch touch member 8. The plurality of travel switches 9 are electrically connected to the PLC controller 18. When the monitoring module performs broken yarn inspection, whenever it moves to a traveller monitoring position, the switch touch member 8 touches the travel switch 9 at this position. The travel switch 9 sends a control signal to the PLC controller 18. The PLC controller 18 controls the light-emitting diode 19 to emit a monitoring light once. If the photosensitive triode 20 receives the reflected light, it sends a normal signal to the PLC controller 18. And as long as there is a situation where the photosensitive triode 20 does not receive the reflected light once in the primary detection position A and the secondary detection position B of each ring 2, the PLC controller 18 sends a broken yarn signal to notify the staff that a broken yarn situation has occurred.

[0029] As Figure 3 and Figure 4 shown, the support bracket 7 is connected to the monitoring module through an adjustment assembly. As required, the adjustment assembly can adjust the height position of the monitoring module and the distance relative to the traveller 3.

[0030] As Figure 3 and Figure 4 shown, the adjustment assembly includes a horizontally arranged horizontal adjustment rod 10. One end of the horizontal adjustment rod 10 is fixed on the support bracket 7. A horizontal sliding sleeve 13 is slidably connected to the horizontal adjustment rod 10. The lower end of the horizontal sliding sleeve 13 is connected to a first locking bolt 14 by a thread. One end of the first locking bolt 14 passes through the horizontal sliding sleeve 13 and abuts against the horizontal adjustment rod 10. The horizontal sliding sleeve 13 can be locked on the horizontal adjustment rod 10 through the first locking bolt 14. The upper end of the horizontal sliding sleeve 13 is connected to one end of a vertically arranged height adjustment rod 11. A height sliding sleeve 15 is slidably connected to the height adjustment rod 11. One side of the height sliding sleeve 15 is connected to a second locking bolt 16 by a thread. One end of the second locking bolt 16 passes through the height sliding sleeve 15 and abuts against the height adjustment rod 11. The height sliding sleeve 15 can be locked on the height adjustment rod 11 through the second locking bolt 16. The other side of the height sliding sleeve 15 is connected to one end of a mounting rod 17. The other end of the mounting rod 17 is connected to the monitoring module.

[0031] The working principle of the present utility model is as follows: When conducting broken yarn monitoring, the linear drive mechanism drives the monitoring module to perform linear inspection back and forth along the distribution direction of the spinning spindles 4, so as to realize broken yarn monitoring at multiple positions. When the monitoring module conducts broken yarn inspection, whenever it moves to a traveller monitoring position, the switch contact member 8 touches the travel switch 9 at this position, and the travel switch 9 sends a control signal to the PLC controller 18. The PLC controller 18 controls the light-emitting diode 19 to emit a monitoring light once. If the photosensitive triode 20 receives the reflected light, it sends a normal signal to the PLC controller 18. And as long as there is a situation where the photosensitive triode 20 does not receive the reflected light once in the primary detection position A and the secondary detection position B of each ring 2, the PLC controller 18 sends a broken yarn signal to notify the staff that a broken yarn situation has occurred. The present utility model realizes broken yarn monitoring at multiple positions through a broken yarn monitoring module, reduces the use cost, and improves the economic benefits of the enterprise.
