Detailed implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figures 1 - 6 shown, a corrugated board palletizing device includes a conveying mechanism 3 and a laminating mechanism 5. A glue application mechanism 2 is provided at the feeding port of the conveying mechanism 3. A suction palletizing robot 4 is arranged between the conveying mechanism 3 and the laminating mechanism 5. The suction palletizing robot 4 transfers the corrugated board 1 on the conveying mechanism 3 to the laminating mechanism 5. The glue application mechanism 2 includes a glue tank 6. Power boxes 10 are arranged on both sides of the glue tank 6. A transfer roller 7, a glue application roller 8 and a pressure roller 9 are rotatably arranged between the two power boxes 10. The pressure roller 9 is located above the glue application roller 8, and the transfer roller 7 is located below the glue application roller 8. The lower half of the transfer roller 7 is immersed in the glue in the glue tank 6. The transfer roller 7 transfers the glue in the glue tank 6 to the glue application roller 8. The pressure roller 9 and the glue application roller 8 are in contact with the corrugated board 1 from above and below. The pressure roller 9 and the glue application roller 8 cooperate to convey the corrugated board 1. When the glue application roller 8 contacts the corrugated sheet of the corrugated board 1, glue is applied to the lower part of the corrugated sheet.

[0025] The transfer roller 7, the glue - applying roller 8 and the pressing roller 9 are all coaxially connected with transmission gears 34. The transmission gears 34 on the transfer roller 7 and the glue - applying roller 8 are meshed with each other, and the transmission gears 34 on the pressing roller 9 and the glue - applying roller 8 are meshed with each other. A driving motor is arranged in the glue tank 6. The driving motor is drivingly connected to the transfer roller 7, the glue - applying roller 8 or the pressing roller 9, and then drives the other two to rotate through the meshed transmission gears 34.

[0026] Due to the structural characteristics of the corrugated plate 1, glue needs to be applied at a position close to the trough of the corrugation. Only in this way can the applied glue fully contact the flat surface on the lower corrugated plate 1 to ensure the bonding property and complete the lamination between the two. By arranging a plurality of groups of glue - applying members corresponding to the troughs of the corrugations on the glue - applying roller 8, each group of glue - applying members includes two glue - applying rings 35 arranged on the outer periphery of the glue - applying roller 8. One end of the glue - applying ring 35 has a smaller diameter than the other end. The smaller - diameter ends of the two glue - applying rings 35 are relatively close to each other. A glue - applying inclined surface 36 is formed on the outer periphery of the glue - applying ring 35. The glue - applying inclined surface 36 can contact the position of the corrugation close to the trough, so that the glue transferred to the glue - applying inclined surface 36 is applied to the corrugation. At the same time, since the inner diameter of the glue - applying ring 35 is smaller than the outer diameter, the glue between the glue - applying inclined surface 36 and the corrugation can flow down along the glue - applying inclined surface 36 to cover a larger area.

[0027] A glue - holding ring 37 is installed on the inner - side of the glue - applying ring 35. One end of the glue - holding ring 37 close to the glue - applying ring 35 has a larger diameter than the other end. A glue - holding surface 38 is formed on the outer periphery of the glue - holding ring 37. The distance between the glue - holding surface 38 and the corrugation is relatively large. A relatively large amount of glue can be left in the area between the glue - applying inclined surface 36 and the glue - holding surface 38. Part of this glue can not only be applied to the corrugation, but also flow down along the corrugation to reach the bottom of the trough, so that the trough and the nearby areas of the corrugation are all coated with glue. At the same time, compared with directly applying glue at the trough position of the corrugation, the amount of glue is not too much, so that the glue will not drip from the trough, reducing the pollution of the glue to the environment and also reducing waste.

[0028] A glue - discharging ring 39 is installed on the outer - side of the glue - applying ring 35. One end of the glue - discharging ring 39 close to the glue - applying ring 35 has a larger diameter than the other end. A glue - discharging surface 40 is formed on the outer periphery of the glue - discharging ring 39. Glue is not likely to remain at the glue - discharging surface 40, so that the glue is concentrated in the lower part where the glue - applying inclined surface 36 contacts the corrugation, and the glue in the upper part where the glue - applying inclined surface 36 contacts the corrugation can flow down from the glue - discharging surface 40 as much as possible.

[0029] A transfer ring 41 is provided at the position of the glue - applying ring 35 on the transfer roller 7. A filling ring 43 is provided between the two transfer rings 41. A rotating surface 42 is formed on the outer periphery of the transfer ring 41, and the inclination of the rotating surface 42 is the same as that of the glue - applying inclined surface 36. The distance between the outer periphery of the filling ring 43 and the glue - containing ring 37 and the glue - applying roller 8 is smaller than the distance between the rotating surface 42 and the glue - applying inclined surface 36. In this way, the amount of glue transferred to the glue - applying ring 35 is larger, while the amount of glue transferred between the two glue - applying rings 35 is smaller. Thus, the glue can be applied to the corrugated sheet in the aforementioned manner, minimizing the amount of glue at the bottom of the wave trough of the corrugated sheet and avoiding glue dripping.

[0030] The conveying mechanism 3 includes a chassis 11. On one side of the upper part of the chassis 11 far from the glue - applying mechanism 2, a driving shaft 12 is rotatably installed through a bearing seat. A number of driving wheels 13 are provided on the driving shaft 12. A conveying motor 14 is provided on the chassis 11, and the conveying motor 14 can drive the driving shaft 12 to rotate. The conveying motor 14 and the driving shaft 12 are connected by a belt drive. On one side of the upper part of the chassis 11 close to the glue - applying mechanism 2, a fixed shaft 15 is rotatably installed through a bearing seat. A driven wheel 16 is provided on the fixed shaft 15 at a position corresponding to the driving wheel 13. A circular belt 17 is installed between the driving wheel 13 and the driven wheel 16 with corresponding positions. The position of the circular belt 17 is offset from the position of the glue - applying member. The position of the circular belt 17 is preferably set corresponding to the wave crest of the corrugated sheet. In this way, due to the cooperation between the wave - crest structure of the corrugated sheet and the circular belt 17 to form a limit, the circular belt 17 can effectively support the corrugated sheet, and the corrugated sheet will not be skewed during glue - applying and conveying.

[0031] Furthermore, a limit plate 18 is installed at each position on both sides of the circular belt 17 on the upper part of the chassis 11. The limit plate 18 is arranged along the setting direction of the circular belt 17, and the limit plate 18 is located on the side of the chassis 11 close to the glue - applying mechanism 2. The two limit plates 18 guide the corrugated plate 1 during conveying. Specifically, it is located on the side of the blocking plate 22 close to the glue - applying mechanism 2. A waist - shaped hole is opened on the limit plate 18, and a bolt passes through the waist - shaped hole and is screwed into the chassis 11 to fix the limit plate 18. This installation method enables the installation position of the limit plate 18 to be adjustable, and the distance between the two limit plates 18 can be adjusted according to the size of the corrugated plate 1.

[0032] A blocking cylinder 21 is installed at the middle position of the chassis 11. The blocking cylinder 21 is located below the circular belt 17, and the blocking cylinder 21 is drivingly connected to a blocking plate 22. When the corrugated plate 1 reaches the position on the conveying mechanism 3 close to the laminating mechanism 5 and is transferred by the picking and palletizing robot 4, the blocking cylinder 21 drives the blocking plate 22 to rise, so that the upper end of the blocking plate 22 exceeds the upper part of the circular belt 17, thereby blocking the subsequent corrugated plates 1 and avoiding the subsequent corrugated plates 1 from affecting the transfer.

[0033] The pick-and-place robot 4 includes a robotic arm 25. The robotic arm 25 is drivingly connected to a vacuum chuck tooling 26. The vacuum chuck tooling 26 includes four vacuum chucks. The corrugated board 1 is adsorbed by the vacuum chucks, and then the robotic arm 25 drives the corrugated board 1 adsorbed by the vacuum chucks to complete the transfer.

[0034] On the upper part of the chassis 11, a positioning block 24 is provided. The positioning block 24 is located near the drive shaft 12. On both sides of the upper part of the chassis 11, a positioning cylinder 19 is installed respectively. The positioning cylinder 19 is located between the positioning block 24 and the blocking plate 22. The positioning cylinder 19 is drivingly connected to a positioning plate 20. After the corrugated board 1 reaches the position on the conveying mechanism 3 close to the laminating mechanism 5, it is blocked by the positioning block 24 to limit the continuous advancement of the corrugated board 1. At the same time, the positioning cylinders 19 on both sides respectively drive the positioning plates 20 to approach the corrugated board 1 and press against the corrugated board 1 from both sides, thereby completing the positioning of the corrugated board 1, so that the vacuum chuck tooling 26 driven by the robotic arm 25 can accurately adsorb the corrugated board 1 on the conveying mechanism 3.

[0035] A glue removing plate 23 is installed on the chassis 11. The lower circular belt 17 passes through the glue removing plate 23. The glue falling on the circular belt 17 is removed by the glue removing plate 23 to prevent the glue from solidifying on the circular belt 17 and affecting the normal rotation of the circular belt 17, so that the circular belt 17 can keep the normal conveyance of the corrugated board 1.

[0036] The laminating mechanism 5 includes a support frame 27. On the upper part of the support frame 27, a linear guide rail 28 is provided. A support table 29 is slidably arranged on the linear guide rail 28. On the side of the support frame 27 far from the robotic arm 25, a mounting frame 30 is installed. On the upper part of the mounting frame 30, a pressing cylinder 31 is installed. The pressing cylinder 31 is drivingly connected to a pressing plate 32. The linear guide rail 28 can drive the support table 29 to reach below the pressing plate 32 or leave from below the pressing plate 32 to reach a position close to the robotic arm 25. On both sides of the mounting frame 30 on the support frame 27, a vertical plate 33 is provided respectively. The linear guide rail 28 first controls the support table 29 to move out of the mounting frame 30, and the robotic arm 25 controls the vacuum chuck tooling 26 to reach above the support table 29. The vacuum chuck tooling 26 releases the corrugated board 1, so that the corrugated board 1 falls smoothly and accurately on the corrugated board 1 already on the lower support table 29. The linear guide rail 28 then controls the support table 29 to reach inside the mounting frame 30. The stacked corrugated boards 1 are positioned by the vertical plates 33. At the same time, positioning members can also be provided on the support table 29 inside the mounting frame 30, so as to complete the positioning from four directions of front, back, left and right. Ensure that when the pressing cylinder 31 controls the pressing plate 32 to descend and press on the corrugated board 1, the position of the corrugated board 1 will not shift, and each of the stacked corrugated boards 1 is in the corresponding position. The pressing plate 32 presses on the uppermost corrugated board 1, so that the glue below the corrugated board 1 can fully contact the corrugated board 1 below it, thereby completing the lamination of the corrugated board 1. According to the processing requirements, laminate the corresponding number of corrugated boards 1.
