The transverse driving device 4 is a transverse motor 4-1 with a reduction mechanism 4-2. The gear 4-3 and the rack 3 are connected through a transmission connection to enable the entire device to move laterally under the support and guidance of the transverse slide rail 2.
[0027] Two longitudinal slide rails 5 are fixedly connected above the base 1, with the extension direction of the longitudinal slide rail 5 as the longitudinal direction, a support plate 6 is fixedly connected above the longitudinal slide rail 5, two side plates 7 and a driving block 8 are fixedly connected above the support plate 6, the driving block 8 is fixedly connected to the nut 9, the nut 9 is threadedly connected to the screw 10, both ends of the screw 10 are rotatably connected to the longitudinal bearing seat 11, the end of the screw 10 away from the transverse slide rail 2 passes through the longitudinal bearing seat 11 and is transmission-connected to the longitudinal driven pulley 12-3 of the longitudinal driving device 12, the longitudinal driving device 12 is driven by the longitudinal motor 12-1, the longitudinal active pulley 12-2 transmission-connected to the longitudinal motor 12-1 drives the longitudinal driven pulley 12-3 to rotate through the longitudinal belt 12-4, thereby rotating the screw 10, thereby causing the nut 9 to move axially along the screw 10, that is, the driving block 8 drives the support plate 6 to move longitudinally. Two upper and lower yarn pushing actuators 13 and a yarn pushing driving device 14 are fixedly connected between the two side panels 7, and the side panels 7 are fixedly connected to the support plate 6. Generally speaking, the longitudinal movement motor 12-1 is connected through a belt drive to enable the two yarn pushing actuators 13 to move longitudinally under the support and guidance of the longitudinal movement slide rail 5.
[0028] like Figure 1 , Figure 2 and Figure 3As shown, the yarn pushing actuator 13 includes a mounting seat 13-1 and a mounting plate 13-2, one side of the mounting seat 13-1 is fixedly connected to the mounting plate 13-2, the yarn pushing bearing seat 13-3 is fixedly connected to the mounting seat 13-1, the yarn pushing bearing seat 13-3 is rotatably connected to a rotating shaft 13-4, and both ends of the rotating shaft 13-4 are transmission-connected to a yarn pushing driven pulley 14-3 of the yarn pushing driving device 14 and an execution pulley 13-5 of the yarn pushing actuator 13, the execution pulley 13-5 and another execution pulley 13-5 rotatably connected to the mounting plate 13-2 are transmission-connected via an execution belt 13-6, and a transmission block 13-7 is fixedly connected to the mounting plate 13-2. The driving block 13-7 is fixedly connected to the cylinder seat 13-8, and a rotary cylinder 13-9 is fixedly connected to the cylinder seat 13-8, and the rotary cylinder 13-9 drives the upper yarn pushing plate 13-10 and the lower yarn pushing plate 13-11 to rotate, and the yarn pushing actuator 13 has a limit block 13-12 at the head, and two guide rods 13-13 are connected between the limit block 13-12 and the mounting seat 13-1, and the cylinder seat 13-8 can move back and forth on the guide rod 13-13, that is, the upper yarn pushing plate 13-10 and the lower yarn pushing plate 13-11 can move back and forth and rotate on the guide rod 13-13. The hank can slide on the smooth cover 13-14 of the yarn pushing actuator 13 above, and the yarn supporting plates 13-15 are installed on both sides of the yarn pushing actuator 13 below, which can hold the hank. The yarn pushing driving device 14 includes a yarn pushing motor 14-1, a yarn pushing active pulley 14-2 which is transmission-connected to the yarn pushing motor 14-1, and drives the upper and lower yarn pushing driven pulleys 14-3 to rotate through the upper and lower yarn pushing belts 14-4, thereby rotating the rotating shaft 13-4.

[0029] The implementation method of this device: Figure 4 and Figure 5 As shown, when the whole device starts working, it is in the hank storage area and facing the yarn storage device 15, the yarn pushing actuator 13 is at position A far from the hank, and the upper yarn pushing plate 13-10 and the lower yarn pushing plate 13-11 are at position ① far from the hank and remain horizontal. Figure 5 and Figure 6 As shown, the entire device moves laterally to the doffing working area and faces the shaking device 16. Figure 7 As shown, the yarn pushing actuator 13 moves longitudinally to position B near the skein, and at the same time, the upper yarn pushing plate 13-10 and the lower yarn pushing plate 13-11 move longitudinally to position ② near the skein and remain horizontal. At this time, the upper and lower yarn pushing actuators 13 have been extended into the shaking device 16. Figure 8 As shown, the shaking device 16 operates to make the two upper yarn bundles loosen and fall onto the upper and lower yarn pushing actuators 13. Fig. 9 As shown, the upper yarn pushing plate 13-10 and the lower yarn pushing plate 13-11 rotate 90° to a vertical state, and then the upper yarn pushing plate 13-10 and the lower yarn pushing plate 13-11 move longitudinally to position ③, and at the same time, the yarn pushing actuator 13 moves longitudinally to position A. The moving distance of the upper yarn pushing plate 13-10 and the lower yarn pushing plate 13-11 plus the moving distance of the yarn pushing actuator 13 can make the skein completely separate from the shaking device 16 and fall on the yarn pushing actuator 13. Then the whole device returns to the skein storage area, ready to put the yarn on the yarn pushing actuator 13 on the yarn storage device 15, and at the same time, the shaking device 16 also returns to its original position. Then as Fig.10 As shown, the upper yarn pushing plate 13-10 and the lower yarn pushing plate 13-11 move longitudinally to position ②, and at the same time, the lower yarn pushing plate 13-11 rotates 90° to a horizontal state to prevent the existing skein on the yarn storage device 15 from being entangled on the lower yarn pushing plate 13-11. Fig.11 As shown, the yarn pushing actuator 13 moves longitudinally to a certain distance to position C, that is, the upper yarn pushing plate 13-10 pushes the existing hank on the yarn storage device 15 longitudinally by an equal distance to make room for the hank to be dropped on the yarn pushing actuator 13, and the distance is not less than the width of the two bundles of yarn dropped, so as to minimize the overlap of the two bundles of yarn. Fig.12 As shown, the yarn pushing actuator 13 moves longitudinally to position A, then the upper yarn pushing plate 13-10 rotates 90° horizontally, then the upper yarn pushing plate 13-10 and the lower yarn pushing plate 13-11 move longitudinally to position 1, and then the upper yarn pushing plate 13-10 and the lower yarn pushing plate 13-11 rotate 90° vertically. Fig.13 As shown, the upper yarn pushing plate 13-10 and the lower yarn pushing plate 13-11 move longitudinally to position ②, and the hank on the yarn pushing actuator 13 is completely dropped onto the yarn storage device 15. Finally, the device returns to the state of starting to doff the yarn, and the doffing and yarn releasing action is fully completed.
