[0043] Continue to refer to Figures 1 to 7 When the utility model is used, the swing seat 331 is set on the shaft seat 324, so that the guide column 35 is located in the guide hole 340 of the guide plate 34, and the swing bracket 330 is set on the swing seat 331 so that the swing bracket 330 is parallel to the leather storage rack 1, and the reverse thread screw 332 is adjusted. The reverse thread screw 332 pushes the swing seat 331, and the swing seat 331 swings around the rotating shaft 325 under the guidance of the guide plate 34 and the guide column 35. The swing seat 331 drives the swing bracket 330 to swing, thereby adjusting the angle of the adsorption component 30 set on the swing bracket 330, and adjusting the angle of the adsorption component 30 according to the surface curvature of the leather storage rack 1 actually used.

[0044] The servo motor 323 drives the lifting plate 322 to slide along the slide rail 320. The slide rail 320 is arranged along the inclined moving surface 310. The lifting plate 322 slides along the slide rail 320 so that the lifting plate 322 can be tilted and moved toward one side of the leather storage rack 1. After the lifting plate 322 slides to the pneumatic suction cup 301 to fit and absorb the leather, the servo motor 323 drives the lifting plate 322 to slide upward. The lifting plate 322 drives the pneumatic suction cup 301 away from the leather storage rack 1, and lifts the leather absorbed on the pneumatic suction cup 301, so that a material-taking space is formed between the leather and the next piece of leather, which facilitates the insertion of the feeder 2 from the material-taking space and the material-taking. The guide plate 34 and the guide column 35 ensure the swinging track and stability of the swing seat 331. Since leather is a flexible material, when the leather is placed on the leather storage rack, the surface of the leather will present an irregular wave state. The suction piece 30 is driven by the lifting mechanism 32 to approach the leather, and the telescopic cylinder 300 drives the suction cup seat 302 to drive the pneumatic suction cup 301 to move toward the leather. After the pneumatic suction cup 301 fits the leather, the telescopic cylinder 300 continues to control the movement of the pneumatic suction cup 301, and the leather presses against the pneumatic suction cup 301 to make the pneumatic suction cup 301 slide toward the direction of the proximity switch 303. When the proximity switch 303 detects the air After the pneumatic suction cup 301 is moved, the proximity switch 303 performs feedback control to stop the telescopic cylinder 300, so that the pneumatic suction cup 301 stops moving. Each adsorption component 30 is independently controlled, so that the pneumatic suction cup 301 on each adsorption component 30 will be in different positions due to the shape of the leather surface, forming an irregular wave state that fits the leather surface, so that the adsorption can achieve the best effect and improve the stability of the adsorption lifting. The floating spring can provide buffering when the pneumatic suction cup 301 hits the leather, and can also reset the pneumatic suction cup 301 after the lifting is completed.

[0045] The robot 20 drives the frame 21 to move the linkage belt 23 into the material taking space. The linkage belt 23 stretched tight on the two rotating shafts 22 lifts the leather. Since the linkage belt 23 rotates under the drive of the driving motor 24, the flatness of the leather can be maintained. The robot 20 transports the leather to one end of the conveying device 4 so that the leather contacts the flattening roller 50. The leather is driven by the flattening roller 50 to detach from the linkage belt 23. The rotation of the linkage belt 23 can assist in transferring the leather to the flattening roller 50. After the leather is completely transferred, the loading is completed.

[0046] The driving mechanism 52 drives the flattening roller 50 to rotate, and the rotation speed of the flattening roller 50 is lower than the rotation speed of the conveying device 4. The leather is transferred to the flattening roller 50 by the feeder 2, and the flattening roller 50 feeds the leather into the conveying device 4. Due to the differential operation between the conveying device 4 and the flattening roller 50, the leather can be kept flat. The anti-rolling rod 540 and the anti-rolling wire 541 can prevent the leather from being rolled into the flattening roller 50. When there are inward folded parts on both sides of the leather, when the leather is conveyed to the swing rod 530, the driving cylinder 531 is started, and the driving cylinder 531 drives the swing rod 530 to rotate around the pin toward the side away from the flattening roller 50. The swing rod 530 can swing 90° under the drive of the driving cylinder 531. The swing rod 530 drives the folded part of the leather to unfold, so that the leather is completely spread out to prevent the leather from folding. After the leather completely leaves the swing rod 530, the driving cylinder 531 restores the swing rod 530 to the standby position. An arc-shaped protective surface 5302 is formed on the swing rod 530, so that the contact surface between the swing rod 530 and the leather is a rounded surface, thereby preventing the leather from being damaged during the unfolding process. The fully unfolded leather is transported to the processing position by the conveying device 4 and then processed in the next step.

[0047] The above is only a specific implementation of the present utility model, but the design concept of the present utility model is not limited to this. Any non-substantial changes to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
