[0030] S2. When the first laser sensor 20 at the lower end of the first baffle 18 does not detect the scarf, the reduction motor 11 drives the scarf on the horizontal conveyor belt 6 to move rightward to the first baffle 18. When the first laser sensor 20 senses the scarf, the reduction motor 11 and the horizontal conveyor belt 6 stop conveying the scarf.

[0031] S3. When the second laser sensor 21 at the upper end of the first baffle 18 does not detect the scarf, the servo electric cylinder 12 drives the connecting rod 14 and the lifting rod 13 of the vertical lifting assembly 7 to rise, pushing the scarf up until the second laser sensor 21 senses a signal from the scarf, and the servo electric cylinder 12 and the lifting rod 13 stop rising.

[0032] S4, the first cylinder 24 drives the connecting plate 23 and the suction cup 22 to descend, the suction cup 22 draws air and sucks a piece of scarf, the first cylinder 24 drives the connecting plate 23 and the suction cup 23 to rise and reset, and the head of the scarf is lifted.

[0033] S5, the rodless cylinder 27 with buffer drives the connecting piece 28, the slide cylinder 26, and the gripper 25 to move, the slide cylinder 26 is pushed out to make the gripper 25 grab the scarf, the suction cup 22 stops pumping air and releases the scarf, then the rodless cylinder 27 retreats, and the scarf is pulled away; at this time, the second laser sensor 21 detects that there is no scarf, the servo electric cylinder 12 and the lifting rod 13 push the scarf up until the second laser sensor 21 senses the scarf and sends a signal, and the servo electric cylinder 12 and the lifting rod 13 stop rising.

[0034] S6. When the rodless cylinder 27 with the scarf retreats to the sensing position of the third sensor 29, the slide cylinder rises and resets, the gripper is released, and the scarf is placed in the packaging box 30; the rodless cylinder 27 with buffer continues to retreat and reset.

[0035] S7, repeat steps S4-S6; until the last scarf is taken away, the second laser sensor 21 detects that there is no scarf, and the servo electric cylinder 12 drives the connecting rod 14 of the vertical lifting assembly 7 to rise to the position of the first sensor 15, the first sensor 15 sends a signal, the servo electric cylinder 12 drives the connecting rod 14 of the vertical lifting plate assembly 7 to descend to the position of the second sensor 16, the second sensor 16 sends a signal, and when the first laser sensor 20 does not detect the scarf, the reduction motor 11 drives the scarf on the horizontal conveyor belt 6 to move right to the first baffle 18, and when the first laser sensor 20 senses the scarf, the reduction motor 11 and the conveyor belt stop conveying the scarf.

[0036] 9. Repeat steps S4 to S8.
