[0002] The loom, also known as a spinning machine, weaving machine, or cotton spinning machine, was originally a human-powered loom. Research on shuttleless loom technology began in the 19th century, and it was gradually introduced to the international market from the 1950s onwards. Since the 1970s, many new types of shuttleless looms have been introduced to the market. Shuttleless looms have achieved significant results in improving fabric quality and increasing loom efficiency, and have been widely adopted in countries around the world, accelerating the process of upgrading weaving equipment. In many developed countries, the market share of shuttleless looms has reached approximately 80%, and a major trend of replacing shuttle looms with shuttleless looms has emerged.

[0016] A method for using an automatic weft tube changing machine includes the following steps:

[0017] S1. Pass the weft thread through the upper and lower threading holes and the guide groove in sequence, operate the first pneumatic finger to hold the thread end, and place the weft tube into the placement box;

[0018] S2. Operate the first cylinder to move the lifting plate upwards, the lifting plate lifts the weft tube between the winding assembly and the cutting assembly. At the same time, operate the third and fourth cylinders to extend, driving the top block and rotating rod to clamp from the front and rear sides of the weft tube. Operate the first cylinder to reset the lifting plate. Operate the linear module to move the light emitter and the wire end on the cycloidal assembly to the through hole of the weft tube. Operate the second cylinder to rotate the connecting block. The connecting block drives the suction nozzle and the light receiver on the mounting frame to rotate to the right and perpendicular to the top of the weft tube. Turn on the second motor to drive the top block to rotate the weft tube until the light emitted by the lower light emitter is received by the light receiver. Then stop the second motor, open the suction nozzle to generate suction, and at the same time operate the first pneumatic finger to release the clamping state of the wire end, thereby passing the wire end out from the through hole of the weft tube. Close the suction nozzle, and operate the second cylinder to reset the suction nozzle.

[0019] S3. Start the second motor to drive the top block to rotate with the weft tube and perform the weft tube winding operation. During the winding process, operate the linear module to move the cycloidal assembly as a whole, start the first motor to rotate the threaded rod, drive the threaded slider to move back and forth, and the threaded slider with the wire groove changes the winding position of the weft yarn on the weft tube. During the winding process, the yarn passes through the meter wheel, and the controller automatically calculates the winding length and the number of shuttles for the next weaving of the loom. The controller will stop the second motor after the weft tube has wound a sufficient length of yarn.

[0020] S4. Start the third motor to rotate the gear, which drives the synchronous toothed belt to rotate synchronously. The synchronous toothed belt moves the second pneumatic finger on the movable frame to the left until it moves above the weft tube. Operate the sixth cylinder to bring the clamping seat into contact with the weft tube. Operate the second pneumatic finger to clamp the weft tube. At the same time, operate the sixth, third and fourth cylinders to reset, which can release the fixed state of the top block and the rotating rod and make the weft tube move upward. Start the third motor to reverse and reset the movable frame. At this time, the wound weft tube moves above the shuttle of the loom.

[0021] S5. Operate the seventh cylinder to rotate the eighth cylinder on the connecting plate to the left, operate the eighth cylinder to move the third pneumatic finger downward to the outside of the weft thread, operate the third pneumatic finger and the first pneumatic finger to clamp the weft thread, operate the fifth cylinder to move the pneumatic scissors to the weft thread, operate the pneumatic scissors to cut the weft thread, operate the eighth cylinder to move the third pneumatic finger upward, operate the seventh cylinder to reset the eighth cylinder, at this time, the weft thread head also moves to the top of the shuttle.

[0022] S6. Operate the rodless cylinder to move the placement box to the bottom of the shuttle, operate the sixth cylinder to move the wound weft tube downwards and insert it into the shuttle, and the weft tube inside the shuttle falls into the placement box. At the same time, operate the eighth and seventh cylinders to make the cut thread end pass through the thread hole of the shuttle. Then operate the eighth and seventh cylinders to move the third pneumatic finger upwards to reset. After the loom starts working, release the clamp of the third pneumatic finger.

[0023] S7. After the loom shuttle has woven the specified number of shuttles, the loom stops, and the operating positioning cylinder rotates the lever on the connecting plate, which moves the shuttle to the designated position for weft tube installation.

[0024] S8. Operate the ninth cylinder to extend the hook, hooking the weft thread on the weft tube inside the shuttle to the left and into the guide plate. Operate the eleventh cylinder to move the removal wheel downwards, pressing the weft thread onto the rubber wheel. Operate the tenth cylinder to move the cutting knife downwards, cutting the weft thread. Start the fourth motor to rotate the removal wheel, thereby quickly pulling out the remaining weft thread on the weft tube. The photoelectric wire detector can sense whether all the remaining weft thread on the weft tube has been pulled out, thereby controlling the start and stop of the fourth motor. Repeat the above steps to realize the automatic weft tube changing operation of the loom shuttle.

[0025] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0026] 1. This automatic weft tube changing machine and its usage method, through the set threading component, can realize the automatic threading of the weft head through the weft tube without manual threading.

[0027] 2. This automatic weft tube changing machine and its usage method, through the set cycloidal component, can automatically wind and cut the weft yarn next to the loom. It can wind the weft yarn while the loom is running, improving efficiency, without the need for other professional machines to wind the weft or manual handling of the weft tube.

[0028] 3. The automatic weft tube changing machine and its usage method, through the set winding component and cutting component, can clamp the weft tube while driving it to rotate; at the same time, the cutting component can also cut the weft thread.

[0029] 4. The automatic weft tube changing machine and its usage method, through the set tube clamping assembly, can clamp the weft tube and move it back and forth between the winding station and the weft tube installation station.

[0030] 5. The automatic weft tube changing machine and its usage method, through the set excess thread removal component, can hook back the weft thread between the weft tube and the woven fabric, and perform weft thread cutting and weft thread pulling removal operations.

[0031] 6. This automatic weft tube changing machine and its usage method, through the set positioning component, can move the shuttle to the designated position for weft tube installation.

[0032] 7. This automatic weft changing machine and its usage method, through the set meter counting component, can calculate the length of the weft thread.

[0071] A method for using an automatic weft tube changing machine includes the following steps:

[0072] S1. Pass the weft thread through the upper and lower threading holes and the guide groove 508 in sequence, operate the first pneumatic finger 510 to hold the thread end, and place the weft tube into the placement box 304;

[0073] S2. Operate the first cylinder 308 to move the lifting plate 309 upwards. The lifting plate 309 lifts the weft tube between the winding assembly 7 and the cutting assembly 8. Simultaneously, operate the third cylinder 702 and the fourth cylinder 807 to extend, driving the top block 708 and the rotating rod 805 to clamp the weft tube from both the front and rear sides. Operate the first cylinder 308 to reset the lifting plate 309. Operate the linear module 4 to move the light emitter 509 on the cycloidal assembly 5 and the wire end to the through hole of the weft tube. Operate the second cylinder 606 to rotate the connecting block 607. 7. Drive the suction nozzle 604 and the light receiver 605 on the mounting bracket 603 to rotate to the right and perpendicular to the top of the weft tube. Turn on the second motor 705 to drive the top block 708 to rotate with the weft tube until the light emitted by the lower light emitter 509 is received by the light receiver 605. Then stop the second motor 705, open the suction nozzle 604 to generate suction, and at the same time operate the first pneumatic finger 510 to release the clamping state of the wire end, so that the wire end is passed out from the hole of the weft tube. Close the suction nozzle 604 and operate the second cylinder 606 to reset the suction nozzle 604.

[0074] S3. Start the second motor 705 to drive the top block 708 to rotate with the weft tube and perform the weft tube winding operation. During the winding process, operate the linear module 4 to move the cycloidal assembly 5 as a whole. Start the first motor 503 to rotate with the thread rod 504. The thread rod 504 drives the thread slider 507 to move back and forth. The thread slider 507 with the wire groove 508 changes the winding position of the weft yarn on the weft tube. During the winding process, the yarn passes through the meter wheel 1205. The controller automatically calculates the winding length and the number of shuttles for the next weaving of the loom. The controller will stop the second motor 705 after the weft tube has wound a sufficient length of yarn.

[0075] S4. Start the third motor 903 to rotate the gear 902. The gear 902 drives the synchronous toothed belt 904 to rotate synchronously. The synchronous toothed belt 904 moves the second pneumatic finger 909 on the movable frame 901 to the left until it moves above the weft tube. Operate the sixth cylinder 906 to bring the clamping seat 907 to fit the weft tube. Operate the second pneumatic finger 909 to clamp the weft tube. At the same time, operate the sixth cylinder 906, the third cylinder 702 and the fourth cylinder 807 to reset. This can release the fixed state of the top block 708 and the rotating rod 805 and make the weft tube move upward. Start the third motor 903 to reverse and reset the movable frame 901. At this time, the wound weft tube moves above the shuttle of the loom.

[0076] S5. Operate the seventh cylinder 911 to rotate the eighth cylinder 912 on the connecting plate 910 to the left. Operate the eighth cylinder 912 to move the third pneumatic finger 913 downward to the outside of the weft thread. Operate the third pneumatic finger 913 and the first pneumatic finger 510 to clamp the weft thread. Operate the fifth cylinder 809 to move the pneumatic scissors 810 to the weft thread. Operate the pneumatic scissors 810 to cut the weft thread. Operate the eighth cylinder 912 to move the third pneumatic finger 913 upward. Operate the seventh cylinder 911 to reset the eighth cylinder 912. At this time, the weft thread head has also moved to the top of the shuttle.

[0077] S6. Operate the rodless cylinder 305 to move the placement box 304 to the bottom of the shuttle, operate the sixth cylinder 906 to move the wound weft tube downwards and insert it into the shuttle, and the weft tube inside the shuttle falls into the placement box 304. At the same time, operate the eighth cylinder 912 and the seventh cylinder 911 to make the cut thread end pass through the thread hole of the shuttle. Then operate the eighth cylinder 912 and the seventh cylinder 911 to move the third pneumatic finger 913 upwards to reset. After the loom starts working, release the clamping of the third pneumatic finger 913.

[0078] S7. After the loom shuttle has woven the specified number of shuttles, the loom stops, and the positioning cylinder 1102 rotates the lever 1104 on the connecting plate 1103. The lever 1104 moves the shuttle to the designated position for weft tube installation.

[0079] S8. Operate the ninth cylinder 1002 to extend the hook 1003, hooking the weft thread on the weft tube inside the shuttle to the left and into the guide plate 1009. Operate the eleventh cylinder 1006 to move the removal wheel 1008 downward to press the weft thread onto the rubber wheel 1011. Operate the tenth cylinder 1004 to move the cutting knife 1005 downward to cut the weft thread. Start the fourth motor 1007 to rotate the removal wheel 1008, thereby quickly pulling out the remaining weft thread on the weft tube. The photoelectric wire detection sensor 1010 can sense whether all the remaining weft thread on the weft tube has been pulled out, thereby controlling the start and stop of the fourth motor 1007. Repeat the above steps to realize the automatic weft tube changing operation of the loom shuttle.

Operate the rodless cylinder (305) to move the placement box (304) to the bottom of the shuttle, operate the sixth cylinder (906) to insert the wound weft tube downward into the shuttle, and the weft tube inside the shuttle falls into the placement box (304). At the same time, operate the eighth cylinder (912) and the seventh cylinder (911) to make the cut thread end pass through the thread hole of the shuttle. Then operate the eighth cylinder (912) and the seventh cylinder (911) to move the third pneumatic finger (913) upward to reset. After the loom starts working, release the clamping of the third pneumatic finger (913). S7. After the loom shuttle has woven the specified number of shuttles, the loom stops, and the positioning cylinder (1102) rotates with the actuating rod (1104) on the connecting plate (1103). The actuating rod (1104) moves the shuttle to the designated position for weft tube installation. S8. Operate the ninth cylinder (1002) to extend the hook (1003) and hook the weft thread on the weft tube inside the shuttle to the left and into the guide plate (1009). Operate the eleventh cylinder (1006) to move the removal wheel (1008) downward to press the weft thread onto the rubber wheel (1011). Operate the tenth cylinder (1004) to move the cutting knife (1005) downward to cut the weft thread. Start the fourth motor (1007) to rotate the removal wheel (1008) and quickly pull out the remaining weft thread on the weft tube.
