[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 In the embodiment of the utility model, an automatic stacking device for aluminum foil lunch boxes includes a conveying mechanism 1 and a picking mechanism 2. The top surface of the picking mechanism 2 is provided with a placing mechanism 3. The picking mechanism 2 includes a support seat 21. The top surface of the support seat 21 is rotatably connected to a cylinder 22. The output end of the cylinder 22 is fixedly connected to an H-shaped plate 23. A plurality of suction members 24 are evenly spaced on both sides of the bottom surface of the H-shaped plate 23. The suction member 24 includes a connecting pipe 241. The bottom end of the connecting pipe 241 is fixedly connected to a cylindrical shell 242 connected to the connecting pipe 241 at a corresponding position. The bottom surface of the cylindrical shell 242 is annular. A plurality of suction cups are fixed through the angle, wherein a connecting pipe 241 in the middle is fixed through the H-shaped plate 23, and both ends of the two sides of the H-shaped plate 23 are penetrated with a sliding hole 231 with a cross-shaped cross section, and a plurality of connecting pipes 241 located on both sides of the middle connecting pipe 241 slide through the sliding hole 231 at the corresponding position respectively, and an air pipe 243 is fixedly connected to the inside of the connecting pipe 241, and scales 233 are printed on both sides of the top surface of the H-shaped plate 23, and a motor 25 is fixedly connected to the bottom surface of the support seat 21, and the output end of the motor 25 penetrates the top surface of the support seat 21 and is fixed to the cylinder 22.

[0023] Specifically, first, multiple air pipes 243 are connected to an external air pump through multiple three-way pipes or four-way pipes, and then the aluminum foil lunch boxes are placed on the conveying mechanism 1 at equal intervals, and the interval between two adjacent cylindrical shells 242 on the same side of the H-shaped plate 23 is adjusted according to the interval between two adjacent lunch boxes, and then the placement mechanism 3 is slightly lowered so that the top surface of the placement mechanism 3 is lower than the top surface of the conveyor belt in the conveying mechanism 1, and then the conveying mechanism 1 is started to move multiple equally spaced lunch boxes thereon, and when multiple lunch boxes are respectively moved to the bottom of the cylindrical shells 242 at corresponding positions, the conveying mechanism 1 is closed, and then the H-shaped plate 23 is moved downward by starting the cylinder 1 22 until the multiple suction cups on the bottom surface of the cylindrical shell 242 are in close contact with the inner bottom surface of the lunch box at the corresponding position, and then the gas in the multiple cylindrical shells 242 is extracted by the operation of the external air pump, so that the lunch box is adsorbed between the multiple suction cups at the corresponding position, and then after the cylinder 1 22 is restored to its original position, the motor 25 is started to So that the cylinder 1 22 drives the H-shaped plate 23 to rotate, until the H-shaped plate 23 rotates 180 degrees, the motor 25 automatically stops, and then the cylinder 1 22 is started again to move the H-shaped plate 23 downward, and the multiple cylindrical shells 242 are inflated by the external air pump, so that the lunch boxes adsorbed on the multiple suction cups fall onto the placement mechanism 3, and then the placement mechanism 3 moves down a small section, and at the same time the external air pump extracts the gas in the multiple cylindrical shells 242, and the lunch boxes on the conveying mechanism 1 are sucked again. Since the top surface of the placement mechanism 3 is lower than the top surface of the conveyor belt in the conveying mechanism 1, the multiple suction cups located directly above the placement mechanism 3 do not contact the lunch boxes on the placement mechanism 3, so the suction cups cannot suck the lunch boxes on the placement mechanism 3, and then the above operation is repeated to realize automatic stacking of aluminum foil lunch boxes. The device can adjust the distance between two adjacent cylindrical shells 242 on the same side of the H-shaped plate 23, so as to facilitate the picking and stacking of lunch boxes of different sizes, making the device more practical and having a wider range of applications.

At this time, the protrusion 282 returns to its original position under the action of the spring 1 at the corresponding position, so that the multiple blocks at the corresponding position are engaged with the rack 232 at the corresponding position, which can prevent the connecting plate 26 from moving, and then the distance between the center lines of the two adjacent connecting plates 26 is adjusted in the same way.
