Description

Technical Field

[0001] The utility model relates to the field of leather material extraction, in particular to an adsorption device used for leather material extraction. Background Art

[0002] Leather is a commonly used material in today's society. It is often used in making shoes, clothes and some daily necessities. During the leather cutting process, since leather itself is a flexible material, it is impossible to use a rigid manipulator to grab and feed it. The existing technology uses a frame-type loader in conjunction with a manipulator for feeding. However, due to the flexible nature of the leather itself, the leather is often drooping and sticking to each other on the leather storage rack. The interval between the leathers is very narrow, and it is difficult for the loader to separate the materials when taking them, which affects the feeding speed. Utility Model Content

[0019] Fourth, the swing seat is guided by setting a guide plate and a guide column to ensure that the swinging motion will not shake along the trajectory, making the adjustment of the swing seat more stable and accurate.

[0020] Fifth, the telescopic cylinder is used to control the extension and retraction of the pneumatic suction cup. When the pneumatic suction cup is against the leather, the pneumatic suction cup can slide on the suction cup seat. The floating spring buffers the pneumatic suction cup. The telescopic cylinder continuously controls the pneumatic suction cup to extend until the pneumatic suction cup triggers the proximity switch. The proximity switch feedback information controls the telescopic cylinder to stop. The position of each pneumatic suction cup can be adjusted according to the actual state of the leather to be adsorbed. Multiple adsorption parts form an irregular wave shape that matches the surface state of the leather, so that the pneumatic suction cup fits the leather surface better and achieves the best adsorption effect.

DETAILED DESCRIPTION

[0024] The present invention is further described below through specific implementation methods.

[0025] Reference Figure 1 and Figure 2The utility model discloses an adsorption device for leather material collection, which is used for adsorbing and lifting leather on a leather storage rack, and comprises a workbench 1, a lifting mechanism 2, a swinging mechanism 3, a plurality of adsorption members 4, a guide plate 5 and a guide column 6.

The two slide rails 20 are arranged in parallel and spaced apart on the moving surface 10, and the slide rails 20 extend along the extension direction of the moving surface 10. The sliders 21 can be slidably arranged on the slide rails 20. Two sliders 21 are arranged on each slide rail 20. The lifting plate 22 is arranged on the sliders 21. The four sliders 21 are respectively located at the four corners of the lifting plate 22. The servo motor 23 is connected to and drives the lifting plate 22 to slide. The swing mechanism 3 is arranged on the lifting plate 22, and the servo motor 23 is arranged between the two slide rails 20.

[0027] The swing mechanism 3 includes a swing bracket 30, a swing seat 31 and a reverse threaded screw 32. The swing seat 31 is rotatably arranged on the lifting mechanism 2 and the swing mechanism 3 can move with the lifting mechanism 2. The swing bracket 30 is arranged on the swing seat 31. One end of the reverse threaded screw 32 is rotatably connected to the swing seat 31, and the other end is rotatably connected to the lifting plate 22. Two rotating shaft seats 24 are arranged on the lifting mechanism 2. The rotating shaft seats 24 are provided with a rotating shaft 25. The two rotating shaft seats 24 are arranged at intervals. The swing seat 31 has an insertion portion 310 corresponding to the rotating shaft seat 24. The insertion portion 310 is rotatably arranged on the rotating shaft seat 24 through the rotating shaft 25. The rotating shaft seat 24 includes two fixed plates 240 arranged at intervals, the two fixed plates 240 are provided with a first through hole, the insertion portion 310 is provided with a second through hole, the insertion portion 310 is inserted between the two fixed plates 240 so that the second through hole is directly opposite to the first through hole, and the rotating shaft 25 is arranged through the first through hole and the second through hole. A limiting portion 250 is formed at one end of the rotating shaft 25, and a pin hole is formed at the other end. The diameter of the limiting portion 250 is larger than the diameter of the first through hole. The rotating shaft 25 is arranged on the rotating shaft seat 24, the limiting portion 250 is pressed against one side of the fixed plate 240, the pin hole protrudes from the other side of the fixed plate 240, and a plug 251 is arranged in the pin hole.

[0028] The guide plate 5 is arranged on the lifting mechanism 2, and a guide hole 50 is opened on the guide plate 5. A mounting hole is opened on the side wall of the swing seat 31, and the guide column 6 passes through the guide hole 50 and is arranged in the mounting hole. The adsorbent 4 includes a telescopic cylinder 40 and a pneumatic suction cup 41. The telescopic cylinder 40 is arranged on the swing bracket 30, and the pneumatic suction cup 41 is arranged on the output end of the telescopic cylinder 40. A suction cup seat 42 is arranged at the output end of the telescopic cylinder 40, and the pneumatic suction cup 41 is slidably arranged on the suction cup seat 42 and the pneumatic suction cup 41 faces the side away from the telescopic cylinder 40. A floating spring is arranged between the pneumatic suction cup 41 and the suction cup seat 42, and a proximity switch 43 is arranged on the side of the suction cup seat 42 close to the telescopic cylinder 40.

[0029] Continue to refer to Figure 1 and Figure 2 When the utility model is used, the swing seat 31 is set on the rotating shaft seat 24, so that the guide column 6 is located in the guide hole 50 of the guide plate 5, and the swing bracket 30 is set on the swing seat 31 so that the swing bracket 31 is parallel to the leather storage rack, and the reverse thread screw 32 is adjusted. The reverse thread screw 32 pushes and pushes the swing seat 31. The swing seat 31 swings around the rotating shaft 25 under the guidance of the guide plates 5 and 6. The swing seat 31 drives the swing bracket 30 to swing, thereby adjusting the angle of the adsorption component 4 set on the swing bracket 30, and adjusting the angle of the adsorption component 4 according to the surface curvature of the leather storage rack actually used.

[0030] The servo motor 23 drives the lifting plate 22 to slide along the slide rail 20. The slide rail 20 is arranged along the inclined moving surface 10. The lifting plate 22 slides along the slide rail 20 so that the lifting plate 22 can be tilted and moved toward one side of the leather storage rack. After the lifting plate 22 slides to the pneumatic suction cup 41 to fit and absorb the leather, the servo motor 23 drives the lifting plate 22 to slide upward. The lifting plate 22 drives the pneumatic suction cup 41 away from the leather storage rack, and lifts the leather absorbed on the pneumatic suction cup 41, so that a material-taking space is formed between the leather and the next piece of leather, which facilitates the loading machine to insert and take the material from the material-taking space. The guide plate 5 and the guide column 6 ensure the swing trajectory and stability of the swing seat 31. 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 adsorbent 4 is driven by the lifting mechanism 2 to approach the leather, and the telescopic cylinder 40 drives the suction cup seat 42 to drive the pneumatic suction cup 41 to move toward the leather. After the pneumatic suction cup 41 fits the leather, the telescopic cylinder 40 continues to control the movement of the pneumatic suction cup 41, and the leather presses against the pneumatic suction cup 41 to make the pneumatic suction cup 41 slide toward the direction of the proximity switch 43. When the proximity switch 43 detects the pneumatic suction cup 41, the proximity switch 43 performs feedback control to stop the telescopic cylinder 40, so that the pneumatic suction cup 41 stops moving. Each adsorbent 4 is independently controlled, so that the pneumatic suction cup 41 on each adsorbent 4 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 41 presses against the leather, and can also reset the pneumatic suction cup 41 after the lifting is completed.

[0031] 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.
