Description

Technical Field

[0001] This invention relates to the field of palletizing equipment technology, and more specifically, to a corrugated plate palletizing device. Background Technology

[0002] Corrugated sheets possess excellent load-bearing capacity due to their corrugations, and the channels formed between stacked sheets provide good heat exchange performance. In the production of corrugated sheets, a common stacking method involves modifying the workshop floor at the conveyor outlet. This involves excavating a pit in the workshop floor, and the conveyed corrugated sheets fall directly into the pit. This method requires workshop modifications and damages the workshop floor. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a corrugated board stacking device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This invention discloses a corrugated board palletizing device, including a conveying mechanism and a laminating mechanism. A gluing mechanism is provided at the inlet of the conveying mechanism. A palletizing robot is positioned between the conveying mechanism and the laminating mechanism, transferring the corrugated boards from the conveying mechanism to the laminating mechanism. The conveying mechanism includes a base frame. A drive shaft is rotatably mounted on the upper part of the base frame away from the gluing mechanism. Several drive wheels are mounted on the drive shaft. A conveying motor is mounted on the base frame, driving the drive shaft to rotate. A fixed shaft is mounted on the upper part of the base frame near the gluing mechanism. Driven wheels are positioned on the fixed shaft corresponding to the drive wheels. A circular belt is installed between the drive wheels and the driven wheels. A blocking cylinder is installed in the middle of the base frame, located below the circular belt, and is driven by a blocking plate.

[0006] Furthermore, a limiting plate is installed on each side of the circular belt on the upper part of the base frame, with the limiting plate located on the side of the base frame closer to the glue application mechanism.

[0007] Furthermore, the palletizing robot includes a robotic arm, which is driven and connected to a vacuum suction cup fixture.

[0008] Furthermore, a positioning block is provided on the upper part of the base frame, and the positioning block is located near the drive shaft. A positioning cylinder is installed on each side of the upper part of the base frame, and the positioning cylinder is located between the positioning block and the blocking plate. The positioning cylinder is driven by the positioning plate.

[0009] Furthermore, a glue removal plate is installed on the base frame, and a circular belt located at the bottom passes through the glue removal plate.

[0010] Furthermore, the glue application mechanism includes a glue tank, with power boxes on both sides of the glue tank. A transfer roller, a glue application roller, and a pressure roller are rotatably mounted on the power boxes, with the pressure roller located above the glue application roller and the transfer roller located below the glue application roller.

[0011] Furthermore, the transfer roller, the coating roller, and the pressure roller are all coaxially connected with transmission gears. The transmission gears on the transfer roller and the coating roller mesh with each other, and the transmission gears on the pressure roller and the coating roller mesh with each other. A drive motor is installed in the glue tank, and the drive motor drives the transfer roller, the coating roller, or the pressure roller.

[0012] Furthermore, the coating roller is provided with several sets of coating components. Each set of coating components includes two coating rings disposed on the outer periphery of the coating roller. The diameter of one end of the coating ring is smaller than that of the other end. The two coating rings are disposed close to each other at the smaller diameter ends. A coating slope is formed on the outer periphery of the coating rings.

[0013] Furthermore, a glue-holding ring is installed on the inner side of the glue-applying ring. The diameter of the glue-holding ring near the glue-applying ring is larger than the diameter of the other end, and a glue-holding surface is formed on the outer periphery of the glue-holding ring. A glue-removing ring is installed on the outer side of the glue-applying ring. The diameter of the glue-removing ring near the glue-applying ring is larger than the diameter of the other end, and a glue-removing surface is formed on the outer periphery of the glue-removing ring.

[0014] Furthermore, a transfer ring is provided on the transfer roller at the position of the coating ring, and a filling ring is provided between the two transfer rings. A rotating surface is formed on the outer periphery of the transfer ring, and the inclination of the rotating surface is consistent with the coating slope. The distance between the outer periphery of the filling ring and the glue-holding ring and the coating roller is smaller than the distance between the rotating surface and the coating slope.

[0015] The beneficial effects of this invention are: the corrugated sheet portion of the corrugated plate is coated with adhesive by the adhesive coating mechanism and then transferred to the laminating mechanism for lamination, which results in high production efficiency.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1-6 As shown, a corrugated sheet palletizing device includes a conveying mechanism 3 and a laminating mechanism 5. A gluing mechanism 2 is installed at the inlet of the conveying mechanism 3. A palletizing robot 4 is positioned between the conveying mechanism 3 and the laminating mechanism 5, transferring the corrugated sheets 1 from the conveying mechanism 3 to the laminating mechanism 5. The gluing mechanism 2 includes a glue tank 6, with power boxes 10 on both sides of the glue tank 6. A transfer roller 7, a gluing roller 8, and a pressure roller 9 are rotatably arranged between the two power boxes 10. The pressure roller 9 is located above the gluing roller 8, and the transfer roller 7 is located below the gluing 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 gluing roller 8. The pressure roller 9 and the gluing roller 8 press against the corrugated sheets 1 from above and below, cooperating to convey the corrugated sheets 1. During the contact between the gluing roller 8 and the corrugated sheets of the corrugated sheet 1, the glue is applied to the lower part of the corrugated sheets.

[0025] The transfer roller 7, the coating roller 8, and the pressure roller 9 are all coaxially connected to transmission gears 34. The transmission gears 34 on the transfer roller 7 and the coating roller 8 mesh with each other, and the transmission gears 34 on the pressure roller 9 and the coating roller 8 mesh with each other. A drive motor is installed in the glue tank 6. The drive motor drives the transfer roller 7, the coating roller 8, or the pressure roller 9, and then drives the other two to rotate through the meshing transmission gears 34.

[0026] Due to the structural characteristics of the corrugated sheet 1, adhesive needs to be applied near the troughs of the corrugated sheet. This ensures that the applied adhesive makes full contact with the flat surface of the corrugated sheet 1 below, guaranteeing adhesion and completing the bonding process. Several sets of adhesive application components corresponding to the troughs of the corrugated sheet are provided on the adhesive application roller 8. Each set includes two adhesive application rings 35 disposed on the outer periphery of the adhesive application roller 8. The diameter of one end of the adhesive application ring 35 is smaller than that of the other end, and the smaller diameter ends of the two adhesive application rings 35 are positioned close together. An adhesive application slope 36 is formed on the outer periphery of the adhesive application ring 35. The adhesive application slope 36 can contact the area of ​​the corrugated sheet near the trough, thereby transferring the adhesive onto the adhesive application slope 36 and applying it to the corrugated sheet. Simultaneously, because the inner diameter of the adhesive application ring 35 is smaller than the outer diameter, the adhesive between the adhesive application slope 36 and the corrugated sheet can flow down along the adhesive application slope 36, covering a larger area.

[0027] A glue-collecting ring 37 is installed on the inner side of the glue-applying ring 35. The diameter of the glue-collecting ring 37 at the end near the glue-applying ring 35 is larger than the diameter at the other end. A glue-collecting surface 38 is formed on the outer periphery of the glue-collecting ring 37. The distance between the glue-collecting surface 38 and the corrugated sheet is relatively large, allowing more glue to remain in the area between the glue-applying inclined surface 36 and the glue-collecting surface 38. This glue can not only be applied to the corrugated sheet, but some can also flow down the corrugated sheet to the bottom of the trough, thus ensuring that the trough and surrounding areas of the corrugated sheet are coated with glue. At the same time, compared to applying glue directly to the trough of the corrugated sheet, the amount of glue is not too much, preventing glue from dripping from the trough, reducing glue pollution to the environment, and reducing waste.

[0028] A release ring 39 is installed on the outer side of the glue-applying ring 35. The diameter of the end of the release ring 39 closest to the glue-applying ring 35 is larger than the diameter of the other end, and a release surface 40 is formed on the outer periphery of the release ring 39. Glue is less likely to remain on the release surface 40, thus concentrating the glue in the lower part where the glue-applying inclined surface 36 contacts the corrugated sheet, while allowing as much glue as possible to flow down from the release surface 40 from the upper part where the glue-applying inclined surface 36 contacts the corrugated sheet.

[0029] A transfer ring 41 is positioned on the transfer roller 7 at the location of the coating ring 35. A filler ring 43 is positioned between 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 consistent with that of the coating inclined surface 36. The distance between the outer periphery of the filler ring 43 and the glue-holding ring 37 and the coating roller 8 is smaller than the distance between the rotating surface 42 and the coating inclined surface 36. This results in a larger amount of glue being transferred to the coating ring 35, while a smaller amount is transferred between the two coating rings 35. This allows the glue to be applied to the corrugated sheet in the manner described above, minimizing the amount of glue at the bottom of the corrugated sheet troughs and preventing glue dripping.

[0030] The conveying mechanism 3 includes a base frame 11. A drive shaft 12 is rotatably mounted on the upper part of the base frame 11 away from the glue application mechanism 2 via a bearing seat. Several drive wheels 13 are mounted on the drive shaft 12. A conveying motor 14 is mounted on the base frame 11, which drives the drive shaft 12 to rotate. The conveying motor 14 and the drive shaft 12 are connected by a belt drive. A fixed shaft 15 is rotatably mounted on the upper part of the base frame 11 near the glue application mechanism 2 via a bearing seat. A driven wheel 16 is mounted on the fixed shaft 15 at a position corresponding to the drive wheel 13. A round belt 17 is installed between the corresponding drive wheel 13 and driven wheel 16. The position of the round belt 17 is offset from the position of the glue application part. The position of the round belt 17 is preferably set to correspond to the crest of the corrugated sheet. In this way, the crest structure of the corrugated sheet can cooperate with the round belt 17 to form a limit, so that the round belt 17 can effectively support the corrugated sheet and prevent the corrugated sheet from tilting during glue application and conveying.

[0031] Furthermore, a limiting plate 18 is installed on each side of the circular belt 17 on the upper part of the base frame 11. The limiting plates 18 are arranged along the setting direction of the circular belt 17 and are located on the side of the base frame 11 near the glue application mechanism 2. The two limiting plates 18 guide the corrugated plate 1 during conveying. Specifically, they are located on the side of the blocking plate 22 near the glue application mechanism 2. The limiting plates 18 have oval holes, through which bolts are screwed into the base frame 11 to fix the limiting plates 18. This installation method makes the installation position of the limiting plates 18 adjustable, and the distance between the two limiting plates 18 can be adjusted according to the size of the corrugated plate 1.

[0032] A blocking cylinder 21 is installed in the middle of the base frame 11. The blocking cylinder 21 is located below the circular belt 17 and is connected to a blocking plate 22. When the corrugated plate 1 reaches the position on the conveying mechanism 3 near the laminating mechanism 5 and is transferred by the 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 plate 1 and preventing the subsequent corrugated plate 1 from affecting the transfer.

[0033] The palletizing robot 4 includes a robotic arm 25, which is driven by a vacuum suction cup fixture 26. The vacuum suction cup fixture 26 includes four vacuum suction cups. The corrugated plate 1 is adsorbed by the vacuum suction cups, and then the robotic arm 25 drives the corrugated plate 1 adsorbed by the vacuum suction cups to complete the transfer.

[0034] A positioning block 24 is provided on the upper part of the base frame 11, located near the drive shaft 12. A positioning cylinder 19 is installed on each side of the upper part of the base frame 11, positioned between the positioning block 24 and the blocking plate 22. The positioning cylinder 19 drives the positioning plate 20. After the corrugated plate 1 reaches the position on the conveying mechanism 3 near the laminating mechanism 5, it is blocked by the positioning block 24, restricting its further movement. Simultaneously, the positioning cylinders 19 on both sides drive the positioning plate 20 to approach the corrugated plate 1, pressing it against the corrugated plate 1 from both sides, thus completing the positioning of the corrugated plate 1. This allows the vacuum suction cup fixture 26 driven by the robotic arm 25 to accurately pick up the corrugated plate 1 on the conveying mechanism 3.

[0035] A glue removal plate 23 is installed on the base frame 11, and the round belt 17 located at the bottom passes through the glue removal plate 23. The glue removal plate 23 removes the glue that falls on the round belt 17, preventing the glue from solidifying on the round belt 17 and affecting the normal rotation of the round belt 17, so that the round belt 17 can maintain normal conveying of the corrugated plate 1.

[0036] The lamination mechanism 5 includes a support frame 27, with a linear guide rail 28 on its upper part. A support platform 29 is slidably mounted on the linear guide rail 28. A mounting frame 30 is installed on the side of the support frame 27 away from the robotic arm 25. A pressing cylinder 31 is installed on the upper part of the mounting frame 30, and the pressing cylinder 31 drives a pressure plate 32. The linear guide rail 28 can drive the support platform 29 to a position below the pressure plate 32 or away from the pressure plate 32 to a position close to the robotic arm 25. A vertical plate 33 is provided on each side of the mounting frame 30 on the support frame 27. The linear guide rail 28 first controls the support platform 29 to move out of the mounting frame 30, and the robotic arm 25 controls a vacuum suction cup fixture 26 to move above the support platform 29. The vacuum suction cup fixture 26 releases the corrugated plate 1, allowing the corrugated plate 1 to fall smoothly and accurately onto the existing corrugated plate 1 on the lower support platform 29. The linear guide rail 28 then controls the support platform 29 to move into the mounting frame 30. The stacked corrugated sheets 1 are positioned using the vertical plate 33. Positioning components can also be installed within the mounting frame 30 and on the support platform 29, allowing for positioning from four directions: front, back, left, and right. This ensures that when the pressing cylinder 31 controls the pressure plate 32 to descend and press onto the corrugated sheets 1, the position of the corrugated sheets 1 does not shift, and each stacked corrugated sheet 1 is in its corresponding position. The pressure plate 32 presses onto the topmost corrugated sheet 1, ensuring that the adhesive below it makes full contact with the corrugated sheets 1 below it, thus completing the lamination of that corrugated sheet 1. The appropriate number of corrugated sheets 1 are laminated according to processing requirements.
