Step two, head replacement: immediately after the change of the bobbin, the upper yarn with the adhered end and tail yarn is changed, namely the working machine head 1 and the standby machine head 8 are interchanged and rotated clockwise by 180 degrees, when the yarn grabbing device 28 is arranged outside the yarn group, the yarn blocking assembly 7 is required to be additionally arranged for matching, during interchange, the yarn pushing rod 14 in the yarn blocking assembly 7 pushes each bundle of yarn to the yarn grabbing device 28 outside with the yarn group, when the standby machine head 8 is interchanged to about 150 degrees, the yarn is captured by the yarn grabbing device 28 of the standby machine head 8, and meanwhile, the movable isolation plate 3 is vertically swung down by the linkage swing arm 5, so that the movable isolation plate 3 is positioned between the standby machine head 8 and the working machine head 1 and is changed along with the diameter change of the yarn group, and the yarn is normally pulled and wound into the yarn group in the yarn winding area. At this time, the working machine head 1 with the yarn feeding is changed to the position of the standby machine head 8 and stopped, and the pneumatic yarn grabbing assembly 30 and the yarn feeding ring 15 without cutting automatically shrink, so that the manipulator does not need to manually cut yarn to separate and complete the tube taking process.
Thirdly, full cylinder replacement: after the working machine head 1 is fully drawn into a tube, the tube replacement starts, meanwhile, the movable isolation plate 3 is synchronously retracted upwards along with the linkage swing arm 5 to avoid the standby machine head 8, yarns are captured by the yarn grabber 28 of the standby machine head 8 when the standby machine head 8 is exchanged to about 150 degrees, or the yarns are captured by the yarn cluster outside yarn grabber 28 through the push screw 14, the movable isolation plate 3 after avoidance is quickly returned to the side close to the empty machine head under the vertical swing by the linkage swing arm 5, the movable isolation plate 3 is positioned between the standby machine head 8 and the working machine head 1 and is changed along with the diameter change of the yarn cluster, and the yarns are normally drawn and wound to the full tube in a yarn winding area.
Fourth, unloading the cylinder: at this time, the working machine head 1 full of the yarn cylinder is replaced to the position of the standby machine head 8 and stopped, the pneumatic yarn grabbing component 30 and the yarn cutting-free upper yarn ring 15 automatically shrink and are separated from the yarn cylinder, when the pneumatic yarn grabbing component 30 stops rotating at the main shaft 18, the air channel 31 enters the piston pull rod 34 to compress the spring II 37, so that the yarn grabbing device 28 is lower than the surface of the expansion piece 17, the yarn taking cylinder is operated, the wire drawing among yarn groups is realized, the mechanical arm does not need to manually cut yarn to separate to finish the yarn taking and cylinder unloading process, and the third step and the fourth step are repeated, and when the yarn is broken, the first step and the second step are needed to be carried out.
When the pneumatic yarn grabbing assembly 30 rotates on the main shaft 18, the air channel 31 does not intake air, the piston pull rod 34 enables the yarn grabbing device 28 to be higher than the surface of the expansion piece 17 under the supporting and centrifugal actions of the spring II 37, the yarn grabbing process is carried out on yarn, and when the full drum stops rotating, the air channel 31 enters the piston pull rod 34 to compress the spring II 37, so that the yarn grabbing device 28 is lower than the surface of the expansion piece 17.
In summary, the cylinder-changing non-head and tail yarn adhesion wire drawing machine and the control method have the characteristics of compact and simple structure, simplicity in operation, energy conservation, consumption reduction, safety and high efficiency, solve the problems that a manipulator is difficult to process head and tail yarns adhered among yarn groups, and can not draw oversized yarn groups and ultra-long mileage yarns, avoid potential safety hazards of operators, and truly realize the unmanned wire drawing process.
