[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-Figure 8 The present invention provides a technical solution: a carton stacking device for a stereoscopic warehouse, comprising a base 1, a limit plate 45 is fixedly installed at one end of the base 1, an air pipe 3 is fixedly installed at the lower end of the base 1, both sides of the air pipe 3 are connected with turning pipes 2, and each turning pipe 2 is provided with a correction structure for correcting the carton 25 on one side close to the base 1; Four electric push rods 4 are arranged at the lower end of the base 1, and the output end of each electric push rod 4 passes through the upper surface of the base 1, and the output end of each electric push rod 4 is fixedly installed with a bottom plate 5, and a slidable electric push rod 2 6 is arranged at the lower end of the bottom plate 5, and a pushing structure capable of pushing the carton 25 is fixedly installed at the output end of the electric push rod 2 6, and a through groove 9 is penetrated and opened at the upper end of the bottom plate 5, and an L-shaped push plate 10 is installed on the outer side wall of the output end of the electric push rod 2 6, and the L-shaped push plate 10 is slidably connected with the through groove 9 and can push the baffle 14 to rotate at the same time; A torsion spring shaft 7 is fixedly installed on the side of the electric push rod 26 away from the output end, and two rotating plates 11 are rotatably connected on both sides of the torsion spring shaft 7. A through groove 2 12 for the rotating plate 11 to move is provided at the upper end of the bottom plate 5, and a baffle 14 is provided on one side of the base 1. A slide groove 2 38 slidably connected to the rotating plate 11 is provided on one side of the baffle 14. Pulleys 15 are rotatably connected on both sides of the lower end of the baffle 14. The outer wall of the pulley 15 is slidably connected with a slide rail 13, and the slide rail 13 is fixedly connected to the outer wall of the base 1. A pad 16 is placed on the side of the base 1 away from the limit plate 45, and a through groove 3 44 is provided on the side of the baffle 14 close to the L-shaped push plate 10. A circular arc baffle 17 that conflicts with the pad 16 is installed at the lower notch of the through groove 3 44, wherein, reference Figure 2 The backing plate 16 is provided with three slide slot openings, which respectively coincide with the positions of the two slide slots 38 and the through slot 3 44 .

[0018] Specifically, when two cartons 25 are placed on the upper end of the bottom plate 5, the pushing structure will push the two cartons 25 at the upper end of the bottom plate 5 toward the direction close to the baffle 14. At the same time, when the first layer of cartons 25 is pushed by two wheels, the electric push rod 14 will drive the bottom plate 5 to descend, so that the cartons 25 that continue to fall into the upper end of the bottom plate 5 fall to the upper end of the first layer of cartons 25, and so on. At the same time, in the process of pushing the cartons 25, the correction structure can correct both sides of the cartons 25 to prevent the cartons 25 from being skewed during the pushing process. Then, when the cartons 25 at the upper end of the bottom plate 5 are stacked full, the electric push rod 26 will be pressed again. When the L-shaped push plate 10 is in position and drives the L-shaped push plate 10 to move in the direction of the baffle 14, the L-shaped push plate 10 will come into contact with the arc baffle 17. As the L-shaped push plate 10 pushes the arc baffle 17, the arc baffle 17 will drive the baffle 14, the pad 16 and the rotating plate 11 to rotate around the torsion spring shaft 7. The rotating plate 11 passes over the through slot 12 and contacts the carton 25. As the rotating plate 11 rotates, the stacked cartons 25 will also tilt together. During the tilting process, the carton 25 will be affected by gravity and will move toward the angle between the rotating plate 11 and the pad 16, thereby further correcting the position of the carton 25 to prevent it from tipping over.

[0019] Among them, the correction structure includes a piston tube 29, which is fixedly connected to the side of the turning tube 2 close to the base 1. A connecting column 31 is slidably connected in the cavity of the turning tube 2, and the connecting column 31 is slidably connected to the outer wall of the base 1. A piston 30 is fixedly installed on the side of the connecting column 31 close to the piston tube 29. Two connecting columns 35 are also slidably connected on both sides of the base 1, and a correction plate 36 is fixedly installed between the connecting column 35 and the connecting column 31 on the same side.

[0020] Among them, a cavity 28 is opened in the cavity of the base 1, and the inner bottom of the cavity 28 is rotatably connected to a scissor shaft 32, and the outer wall of the scissor shaft 32 is installed with two sets of staggered connecting rods 33, and each connecting rod 33 is slidably connected to a sliding rod 34 at both ends, and the sliding rods 34 are rotatably connected to the corresponding connecting column 2 35 and the connecting column 1 31.

[0021] Specifically, by staggering two connecting rods 33, when one of the connecting columns 31 is sliding, the connecting column 31 on the other side will slide in the opposite direction synchronously, and at the same time drive the correction plate 36 to move synchronously, so that during the movement of the correction plate 36, the carton 25 on the upper end of the bottom plate 5 can be moved closer to the center, and the correction avoids the carton 25 from being misplaced during the stacking process, which may cause it to tip over easily.

[0022] Among them, the pushing structure includes a pushing block 20, on one side of which are fixedly installed two positioning columns 21 slidably connected to the limit plate 45, and the lower end of the pushing block 20 is fixedly installed with a sliding rod 19, the outer wall of the sliding rod 19 is sleeved with a sliding block 18, and the sliding block 18 is fixedly connected to the output end of the electric push rod 26.

[0023] Specifically, when the output end of the electric push rod 26 is active, it will drive the slider 18 to slide together. The sliding process of the slider 18 will drive the push block 20 to slide together through the slide rod 19. At the same time, the positioning column 21 will slide horizontally on the limit plate 45 to limit the push block 20. Then, when the bottom plate 5 descends, the slider 18 will slide downward along the slide rod 19, so that the push block 20 is always at the same height. The bottom plate 5 descends so that the top layer of the stacked cartons 25 can always be in contact with the push block 20.

[0024] Among them, a piston cylinder 46 is fixedly installed on one side of the air pipe 3 close to the baffle 14, an electric push rod three 47 is fixedly installed on the lower end of the base 1, and the output end of the electric push rod three 47 can extend into the cavity of the piston cylinder 46, a piston two 48 is fixedly installed on the output end of the electric push rod three 47, and an L-shaped push plate two 8 is fixedly installed on the outer side wall of the output end of the electric push rod three 47.

[0025] Among them, a slide groove three 41 is opened on one side of the baffle 14, and a limiting column 42 is fixedly installed in the cavity of the slide groove three 41. A push plate 40 is slidably connected to the outer wall of the limiting column 42, and the push plate 40 can contact the pad 16. A spring 43 that contacts the push plate 40 is sleeved on the outer wall of the limiting column 42. A sliding plate 39 is fixedly installed on the end of the push plate 40 away from the base 1, and the sliding plate 39 can contact the L-shaped push plate 2 8.

[0026] Among them, the two sides of the electric push rod 2 6 are fixedly installed with positioning plates 51, the lower end of the bottom plate 5 is fixedly installed with a positioning column 2 52 that can be slidably connected with the positioning plate 51, and the outer wall of the positioning column 2 52 is sleeved with a return spring 53 that contacts the positioning plate 51. Figure 6 At this time, the position of the electric push rod 26 is at the limit height. When the bottom plate 5 needs to continue to move upward to make itself flush with the conveyor belt 24, the electric push rod 4 will continue to push the bottom plate 5 up. At the same time, the positioning column 252 will slide on the positioning plate 51, so that the electric push rod 26 gradually moves away from the bottom plate 5. At the same time, the return spring 53 is compressed. At this time, the bottom plate 5 can be pushed to a position flush with the conveyor belt 24, which is convenient for the conveyor belt 24 to transfer the carton 25 to the upper end of the bottom plate 5, and it is not easy for the carton 25 to tip over during the transmission process.

[0027] Among them, a conveying rack 23 is placed on the side of the base 1 close to the limit plate 45, and a conveying belt 24 is sleeved on the conveying rack 23. A carton 25 is placed on the upper end of the conveying belt 24. A protrusion 49 is fixedly installed at the lower end of the conveying rack 23, and a pressing switch 50 is arranged on one side of the protrusion 49. A conveying rack 26 is placed on the side of the base 1 close to the baffle 14, and a conveying belt 27 is sleeved on the conveying rack 26. A connecting plate 22 that can conflict with the pressing switch 50 is fixedly installed on the far end of the positioning column 21. When the push block 20 starts to push the carton 25, the connecting plate 22 will no longer contact the pressing switch 50, so that the conveying belt 24 will no longer operate to convey the carton 25. At the same time, Figure 1 As shown, a dividing belt is provided in the center of the conveyor belt 24, so that a certain distance is created between the two cartons 25 during the conveyor belt of the conveyor frame 23, so as to facilitate the movement of the slide bar 19, wherein a supporting frame 37 is installed at the lower end of the base 1.

[0028] Specifically, the output end of the electric push rod three 47 pushes the piston two 48 to move, so that the gas inside the piston two 48 flows into the piston tube 29 through the air pipe 3 and the turning tube 2, and then the piston one 30 is pushed by the air pressure, so that the correction plate 36 can correct the carton 25. At the same time, when the through groove three 44 is pushed by the L-shaped push plate one 10 and rotates ninety degrees, the horizontally placed sliding plate 39 will be placed vertically. At this time, after the electric push rod three 47 pushes the piston two 48 and then resets the piston two 48, the output end of the electric push rod three 47 will drive the L-shaped push plate two 8 and the sliding plate 39 to conflict with each other, and then push the sliding plate 39 to move in the direction away from the base 1. During the movement of the sliding plate 39, the push plate 40 will drive the pad 16 to move horizontally, so that the pad 16 and the carton 25 on the upper end of the pad 16 are pushed to the top of the conveyor belt two 27, so that the stacked cartons 25 can complete a fast transmission process.

[0029] Working principle: first, the electric push rod 1 4 will push the bottom plate 5 up so that the height of the bottom plate 5 is flush with the conveyor belt 1 24, then the conveyor belt 1 24 will transfer the two cartons 25 to the upper end of the bottom plate 5, then the bottom plate 5 will drop, and at the same time, the electric push rod 2 6 will drive the push block 20 to push the two cartons 25, so that the cartons 25 are close to the pad 16, and so on. When the first layer is full of four cartons 25, the bottom plate 5 will drop a height so that a new round of cartons 25 can fall above the first layer. Among them, when the carton 25 falls between the two correction plates 36, the electric push rod 3 47 will push the piston 2 48 to slide inside the piston cylinder 46, and the correction plates 36 on both sides will slide synchronously toward the base 1 through the push of air pressure, so that the carton 25 pushed by the push block 20 can be limited, to prevent the carton 25 from sliding away from the base 1 during the pushing process, resulting in dislocation; When the cartons 25 on the upper end of the bottom plate 5 are full, the bottom plate 5 is in the position closest to the base 1, and the electric push rod 26 is in contact with the upper surface of the base 1. At this time, the rotating plate 11 slides to the bottom of the groove 38 of the second slide groove, and the L-shaped push plate 10 is on the same horizontal line as the arc baffle 17. At this time, when the electric push rod 26 is activated and reset again, the L-shaped push plate 10 will conflict with the arc edge of the arc baffle 17 and push the pad 16, the baffle 14 and the rotating plate 11 to rotate around the torsion spring shaft 7, and the pulley 15 will move in an arc around the slide rail 13. During the rotation of the rotating plate 11, the cartons 25 stacked on the upper end of the bottom plate 5 will be pushed to rotate. Through the gravity of the cartons 25 themselves, the cartons 25 slide and gather to one side of the rotating plate 11 and the pad 16, thereby realizing the secondary correction of the stacked cartons 25, and allowing the cartons 25 to quickly leave the stacking bin; Finally, when the baffle 14 is pushed by the L-shaped push plate 10 and rotated ninety degrees, the cartons 25 that were originally stacked vertically will be placed on the pad 16 and stacked horizontally. Then, when the electric push rod 3 47 pushes the piston 2 48 to reset, the L-shaped push plate 28 will begin to slide away from the piston cylinder 46. At this time, the sliding plate 39 that was originally placed horizontally will be placed vertically, so that the L-shaped push plate 28 can contact the sliding plate 39 during the sliding process and push the sliding plate 39 to slide away from the base 1. During the sliding process of the sliding plate 39, the push plate 40 will push the electric push rod 26 to the top of the conveyor belt 27. Then the staff can insert a new pad 16 into one side of the baffle 14 again, thereby improving work efficiency.
