DETAILED DESCRIPTION

[0017] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.

[0018] like Figure 1-3As shown, the utility model provides a single-column destacking device, including a base 1, a turntable 2 is rotatably matched on the base 1, a column 3 is fixedly connected to the turntable 2, a slide rail 4 is arranged inside the column 3, and a slider 5 is slidably matched on the slide rail 4. A first servo motor 6 is arranged on the slider 5 for driving the slider 5 to move on the slide rail 4, and a fixed arm 7 is also fixedly connected to the slider 5, and a rotating arm 8 is rotatably matched at the end of the fixed arm 7, and the rotating arm 8 is driven to rotate by a second servo motor 9. A buffer seat 11 is rotatably matched at the end of the rotating arm 8, and the buffer seat 11 is driven to rotate by a third servo motor 10. The buffer seat 11 includes a connecting rod 14, a sliding sleeve 13 is sleeved on the bottom of the connecting rod 14, and the sliding sleeve 13 is connected to the buffer seat 11 by a spring 15, and a negative pressure vacuum suction cup 12 is fixedly connected to the bottom of the sliding sleeve 13, and an air hole 18 is opened in the negative pressure vacuum suction cup 12.

[0019] The negative pressure vacuum suction cup 12 is connected to a spiral air pump 19 through a negative pressure pipeline 17. A silicone sealing ring 16 is provided on the frame of the negative pressure vacuum suction cup 12 to improve the sealing performance of the negative pressure vacuum suction cup 12 and ensure greater suction force when adsorbing materials.

[0020] When in use, the three servo motors cooperate with each other to drive the negative pressure vacuum suction cup 12 to move to the surface of the stacked material packaging bags, and then the spiral air pump 19 extracts the air in the negative pressure vacuum suction cup 12, so that the material is adsorbed on the negative pressure vacuum suction cup 12 under the action of atmospheric pressure, and then the three servo motors drive the negative pressure vacuum suction cup 12 to move the material to the conveyor, and the spiral air pump 19 turns off the air source to put the material down, completing a destacking action.

[0021] like Figure 4 , as shown in FIG. 5 , a groove 21 is formed on the slide rail 4, a rack 22 is fixed on one side wall of the groove 21, a gear 23 is fixed on the output shaft of the first servo motor 6, the gear 23 meshes with the rack 22, and drives the slider 5 to move up and down along the slide rail 4. The left and right ends of the slider 5 extend to the outer wall of the column 3, and the upper and lower ends are provided with corrugated curtains 20, which extend to the upper and lower ends of the column 3. The corrugated curtain 20 has the same principle as the bellows and has good extensibility, so that the inside of the column 3 is always kept in a sealed state during the movement of the slider 5 to prevent dust from entering.

[0022] The negative pressure pipeline 17 can be fixed to the fixed arm 7 and the rotating arm 8 by buckles to prevent the negative pressure pipeline 17 from being entangled and affecting the material transportation.
