Abstract
Description
Technical Field
[0001] This utility model relates to a defective yarn rejection device in the yarn handling device of an automatic yarn feeding machine used in a winding machine, and the yarn handling device, belonging to the field of textile machinery and equipment. Background Technology
[0002] The applicant's earlier application, Chinese Patent Publication No. CN216549035U, discloses a yarn handling device for an automatic yarn feeding machine. This device is used on an automatic yarn feeding machine of a winding machine. It uses a conveyor belt to transport yarn tubes one by one. The yarn tubes are identified by a visual recognition device, and then a rejecting plate device is used to remove unqualified yarn tubes. The qualified yarn tubes are put into the dropping channel, where a large and small end flipping device moves the yarn tubes so that the small end is always facing down and they slide down the dropping channel. Through visual recognition, unqualified yarn tubes are effectively removed.
[0003] In existing equipment, a resiliently resettable rejection plate is used to move defective yarn tubes along the conveyor belt, pushing the rejection plate open for discharge. However, since the yarn tubes run on the conveyor belt, the friction between the yarn tubes and the conveyor belt is needed to overcome the spring force of the reset torsion spring and push the rejection plate open. This requires sufficient friction between the yarn tubes and the conveyor belt. However, since the yarn tubes fall onto the conveyor belt, the friction between them comes solely from the weight of the yarn tubes. Furthermore, the conical shape of the yarn tubes results in a small contact area with the conveyor belt, leading to very low friction. To use the conveyor belt to move the yarn tubes and push the rejection plate open, the spring force of the reset torsion spring needs to be reduced. There is always a certain probability that the rejection plate will fail to open, or the yarn tubes will slip sideways and fall into the discharge channel of qualified yarn tubes because they cannot push the rejection plate open, or the yarn tubes will get stuck between the rejection plate and the conveyor belt, resulting in discharge failure.
[0004] Therefore, it is necessary to improve the structure of the unqualified yarn feeding mechanism of the automatic yarn feeding machine's yarn handling device in order to achieve efficient feeding. Utility Model Content

[0046] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0047] This utility model is applied to the yarn handling device in the automatic yarn feeding machine of a winding machine, and its overall structure is roughly as follows. Figure 1 As shown, the system includes an input conveyor belt 12, an inspection conveyor belt 13, a vision inspection device 15, a qualified yarn output channel 16, and a yarn output mechanism 18. Yarn 10 is fed into the yarn sorting device from the front-end equipment via the input conveyor belt 12, and then moves along the inspection conveyor belt 13. It first passes through the vision inspection device 15, which judges the quality and size of the yarn 10. Afterward, it moves to the qualified yarn output channel 16. If the yarn 10 is qualified, it is considered qualified. The tube pushing mechanism 2 opposite the tube output channel 16 moves, pushing the tube 10 from the detection conveyor belt 13 into the tube output channel 16. Then, the tube output mechanism 18 moves, outputting the tube 10 with the larger end down and the smaller end up to the back-end equipment for further processing. If the tube 10 is unqualified, such as being an empty tube, the rejection device 3 is activated, opening the rejection plate so that the tube 10 continues to move forward along the detection conveyor belt 13 until it falls from the end of the detection conveyor belt 13 into the tube output mechanism for output.
[0048] This utility model relates to a device for rejecting substandard yarn tubes and a yarn tube sorting device for an automatic yarn feeding machine. Further details can be found in the following references. Figure 2 , Figure 3 Among them, the push tube mechanism 2 further refers to Figure 4 , Figure 5 The tube pushing mechanism 2 is installed on the side of the detection conveyor belt 13 via a side plate 14. The side plate 14 blocks one side of the detection conveyor belt 13 to prevent the yarn tube 10 from rolling off the detection conveyor belt 13. The tube pushing mechanism 2 includes a tube pushing drive element 21 and a push head 22. The tube pushing drive element 21 is a flat cylinder, installed horizontally, so that the output end of the cylinder is horizontally set along the running direction of the detection conveyor belt 13. The output end of the cylinder is equipped with a push head 22. The lower part of the push head 22 is a straight push head 221, which is basically flush with the side plate 14 in the retracted state and does not affect the normal movement of the yarn tube 10. The upper part of the push head 22 is an inclined push head 222, which extends into the detection conveyor belt 13. The push head 22 extends along the running direction of the detection conveyor belt 13 and along the detection... The length of the conveyor belt 13 in the running direction is greater than half the length of the yarn tube 10. When the tube pushing mechanism 2 moves, the cylinder of the tube pushing drive element 21 works, causing the push head 22 to extend towards the detection conveyor belt 13. The flat push head 221 at the bottom of the push head 22 abuts against the side of the yarn tube 10, while the inclined push head 222 at the top of the push head 22 protects the top of the yarn tube 10, so that the yarn tube 10 rolls laterally on the detection conveyor belt 13 until it rolls off the detection conveyor belt 13 into the qualified yarn tube output channel 16. By using a horizontally installed flat cylinder for the tube pushing drive element 21, the push head 22 is lengthened and an inclined push head 222 is set, so that when the tube pushing mechanism 2 works, it can push the yarn tube 10 off the detection conveyor belt 13 very efficiently and reliably.
[0049] This utility model relates to a defective yarn bobbin rejection device, which is further referenced. Figures 6-12 The device includes a frame 31, a rocker arm 32, a rejecting drive element 33, and a reset sensor 35. A rejecting device for defective yarn tubes is installed at the end of the detection conveyor belt 13. Preferably, a yarn tube detection sensor 23 is also installed in front of the rejecting device, positioned above the detection conveyor belt 13. The yarn tube detection sensor 23 is a photoelectric sensor, and the generated detection beam 231 is located in front of the rejecting device. When the yarn tube 10 travels with the detection conveyor belt 13 to the yarn tube detection sensor 23, the front end of the yarn tube 10 blocks the detection beam 231, causing the yarn tube detection sensor 23 to detect that the yarn tube 10 has reached that position. For qualified yarn tubes 10, the pushing mechanism 2 is activated; for unqualified yarn tubes 10, the rejecting device of this invention is activated.
[0050] The defective yarn rejecting device of this utility model has an overall cross-section of the rocker plate 32 that is approximately "L" shaped. The front end of the rocker plate 32 is a rejecting plate 321. When not in operation, the rejecting plate 321 is preferably in a vertical state, located above the detection conveyor belt 13, but not in contact with the surface of the detection conveyor belt 13. The upper side of the rocker plate 32 is preferably a plane, and the rejecting plate 321 is perpendicular to the upper plane, thus forming an "L" shaped longitudinal section. The middle and rear ends of the upper plane of the rocker plate 32 extend downward to form a hinge plate 322. The hinge plate 322 is hinged to the frame 31 through a hinge shaft 312. In a natural state, because the front end of the rocker plate 32 around the hinge shaft 312 is relatively heavy, the rejecting plate 321 will fall naturally under gravity.
[0051] The rear end of the rocker 32 is a drive plate 323, and a rejection drive element 33 is mounted on top of the drive plate 323. The rejection drive element 33 is a cylinder, and the cylinder body 331 is connected to the frame 31 via a drive mounting plate 313. The cylinder body 331 is mounted downwards, and a drive head 333 is mounted at the bottom of the output piston rod 332. The drive head 333 is preferably a ball head and is always in contact with the drive plate 323. When the rejection plate 321 side of the rocker 32 falls naturally due to gravity, the drive plate 323 side is limited by the hinge shaft 312 and moves upwards naturally, thus abutting against the drive head 333 of the rejection drive element 33, thereby limiting the rocker 32 and placing it in a position similar to... Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown, in the non-started state of the defective yarn bobbin rejection device of this utility model, the rejection plate 321 is basically in a vertical state, located above the detection conveyor belt 13, blocking the conveying direction of the yarn bobbin 10. When the push tube mechanism 2 fails to work, it can also block the yarn bobbin 10.
[0052] When the defective yarn rejecting device of this utility model is started, such as Figures 9-12 As shown, the cylinder of the rejection drive element 33 is inflated, causing the piston rod 332 to drive the drive head 333 to extend downward. The drive head 333 presses down against the drive plate 323. The rocker plate 32 is limited by the hinge shaft 312. When the drive plate 323 moves downward, the rejection plate 321 tilts upward, so that the bottom of the rejection plate 321 is H away from the surface of the detection conveyor belt 13. H is greater than the height of the yarn tube 10 on the detection conveyor belt 13. At this time, the unqualified yarn tube 10 can pass through the rejection plate 321 with the detection conveyor belt 13 and reach the end of the detection conveyor belt 13, and be output as unqualified yarn tube.
[0053] The yarn tube 10 moves with the detection conveyor belt 13 until the end of the yarn tube 10 leaves the detection beam 231 of the yarn tube detection sensor 23. After an appropriate delay, the rejection drive element 33 is inflated in the reverse direction, causing the piston rod 332 to drive the drive head 333 to retract upward. At this time, the rocker plate 32 is reset by the gravity of the rejection plate 321.
[0054] Preferably, a detection plate 325 is provided on the side of the rocker 32; a sensor bracket 314 is connected to the side of the rocker 32 on the frame 31, and an oblique arc-shaped sensor groove 315 is opened on it, in which a reset sensor 35 is installed. The reset sensor 35 is a photoelectric sensor or a Hall sensor, which is compatible with the detection plate 325. When the rocker 32 automatically resets, the detection plate 325 will block the front of the reset sensor 35, indicating that the rocker 32 has been reset in place. If the reset sensor 35 fails to detect the detection plate 325 for a long time, it indicates that the rocker 32 has failed to reset normally, and the system needs to issue an alarm and conduct manual troubleshooting.
[0055] The arc-shaped sensor slot 315 allows for flexible adjustment of the installation position of the reset sensor 35, thus facilitating detection of the detection board 325.
[0056] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
