Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, and in particular to an automatic stacking system and method thereof. Background Technology

[0002] To save storage space, processing plants often stack plywood. Stacked plywood allows moisture to evaporate through the spaces between the boards, thus drying them. However, plywood is generally heavy, and manual stacking is physically demanding. Therefore, automated plywood stacking equipment has been developed. To save storage space, plywood needs to be stacked neatly. Furthermore, for better ventilation and moisture evaporation, there should be gaps between pieces of plywood. Most automated stacking equipment simply stacks plywood in one direction. While this solves the space problem, it doesn't address the issue of moisture evaporation. This results in plywood on the sides drying out, while the plywood in the middle is prone to mold and developing an unpleasant odor, significantly impacting the quality of the plywood.

[0003] The technical content disclosed in Chinese patent document (application number: CN202021694659.9, patent title: A Sheet Material Palletizing System) is as follows: This utility model relates to a sheet material palletizing system, including a sheet material quantitative conveying device and a sheet material palletizing device located behind the sheet material quantitative conveying device; the sheet material quantitative conveying device includes a conveyor frame, multiple conveying chains arranged parallel to the conveyor frame, a pressing mechanism on the conveyor frame, and a discharging mechanism located behind the pressing mechanism; the pressing mechanism includes a pressing arm and a pressing arm driving mechanism, the pressing arm driving mechanism being able to drive the pressing arm to rotate downward to separate the sheet material along the conveying direction; the discharging mechanism includes a feeding arm and a feeding arm driving mechanism; the feeding arm driving mechanism is able to drive the feeding arm to flip upward and translate along the conveying direction to feed the sheet material onto the sheet material palletizing device; the sheet material palletizing device includes a palletizing frame, a lifting platform located on the palletizing frame, and a lifting platform driving mechanism; the lifting platform driving mechanism is able to drive the lifting platform to move up and down on the palletizing frame. This application realizes automatic sheet material palletizing, reduces manual operation, and improves efficiency.

[0004] As can be seen from the above implementation plan, the solution has a high degree of automation, and the feeding, conveying and stacking of the boards are all automated, which frees up human labor. However, the stacking method is to place the boards in one direction. This method will cause the boards to be stacked too densely, so that the boards in the middle of the stack cannot get good ventilation. As a result, the boards in the middle cannot evaporate moisture in time and are prone to mold or odor, which will affect the quality of the boards in subsequent use. Summary of the Invention

[0053] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0054] like Figures 1 to 22 As shown, an automatic stacking system and method include a feeding component 1, which is connected to a conveying component 2. The conveying component 2 is connected to an alignment device 4 and a spacing alignment device 5. In this embodiment, two parallel production lines are set up. The first production line includes the feeding component 1, the conveying component 2, the alignment device 4, and the storage lifting component 305. The other production line includes the feeding component 1, the conveying component 2, and the spacing alignment device 5. A rotating material handling robot 3 is set above the spacing alignment device 5 and the storage lifting component 305.

[0055] The strips of sheet material to be stacked are placed on the feeding assembly 1, which separates and conveys them one by one to the conveying assembly 2. The conveying assembly 2 has a quantitative control function, and conveys the quantitative sheet material to the alignment device 4 and the interval alignment device 5 respectively. The alignment device 4 is provided with a quantitative alignment adjustment assembly 405 on its side. By adjusting the quantitative alignment adjustment assembly 405, the alignment position of the sheet material of different lengths can be adjusted. The quantitative alignment power assembly 404 rises, rotating the sheet material in the direction of the quantitative alignment adjustment assembly 405, so that the sheet material is aligned along the quantitative alignment baffle 4053 of the quantitative alignment adjustment assembly 405. The quantitative blocking mechanism 403 rises, intercepting and aligning the sheet material conveyed by the quantitative conveying assembly 402. At this time, the two perpendicular sides of the sheet material are aligned. The external gripping robot grabs the sheet material that has been aligned on the alignment device 4 and places it on the storage lifting assembly 305. The interval alignment device 5 is equipped with a blocking member 5023 that can rise at intervals. The blocking member 5023 blocks the plates at intervals, so that there is a certain gap between the plates. The alignment push plate 5033 aligns the plates blocked by the blocking member 5023 on the side. At this time, the plates on the interval alignment device 5 have completed the alignment of two perpendicular sides. The suction cup 3035 of the rotating material handling robot 3 picks up the plates on the interval alignment device, rotates 90° and moves above the storage lifting assembly 305. The suction cup descends and places the plates on the top of the storage lifting assembly 305. The plates placed by the rotating material handling robot 3 are placed at 90° interlaced with the plates transported from the alignment device and placed on the storage lifting assembly. This allows for air circulation space between the plates due to the gaps, ensuring that the moisture in the plates can evaporate in time. This is very friendly to both the operators and the storage of the plates.

[0056] The rotary material handling robot 3 includes a gantry frame 301, which is slidably connected to a lifting mechanism 302. A suction cup mechanism 303 is rotatably connected to the lower end of the lifting mechanism 302. A suction control mechanism 304 is located above the suction cup mechanism 303. Below the rotary material handling robot 3, an interval alignment frame 504 and a material storage lifting assembly 305 are arranged adjacent to each other. The rotary material handling robot 3 can pick up the sheet metal from the spaced alignment frame 504 and then place it on the storage lifting assembly 305 for stacking. The rotary material handling robot 3 is equipped with a gantry frame 301 and a suction cup mechanism 303. The suction cup mechanism 303 can rotate, lift, and move relative to the gantry frame. Therefore, after the suction cup mechanism 303 picks up the sheet metal from the spaced alignment frame 504, it can rotate 90 degrees before placing it on the storage lifting assembly 305, so that the two layers of sheet metal are stacked in a 90-degree staggered manner. The spaced alignment frame 504... There are gaps between the stacked boards to ensure air circulation and timely evaporation of moisture. Furthermore, as more boards are placed above the storage lifting component 305, its storage surface continuously decreases, ensuring that the suction cups place boards at a consistent height each time. This makes the entire transportation and placement process stable. The equipment is highly automated, and the stacked boards are neat and well-ventilated, making it very user-friendly for both operators and board storage.

[0057] The lifting mechanism 302 includes a suction cup mounting bracket 30292, which is connected to several suction cup mechanisms 303. Each suction cup mechanism 303 includes a suction cup 3035, and the suction cup mounting bracket 30292 and the suction cup 3035 are elastically slidably connected. Each suction cup mechanism 303 includes an elastic upper seat 3031, which is slidably connected to an elastic central shaft 3032. A spring 3033 is inserted into the elastic central shaft 3032. The lower end of the elastic central shaft 3032 is connected to an elastic lower seat 3034. The spring 3033 is located between the elastic upper seat 3031 and the elastic lower seat 3034. The lower end of the elastic lower seat 3034 is connected to the suction cup 3035. Spacer blocks 3036 are spaced apart at the lower end of the suction cup 3035. Because the plates are spaced apart on the spaced alignment frame 504, the spacer blocks 3036 are spaced apart from the suction cup 3035. When the suction cup 3035 picks up the board, it can position the board to prevent it from shifting during the process of being picked up and moved by the suction cup 3035. The spring 3033 can make the suction cup 3035 apply a slight elastic pressure to the board during the process of picking up the board, so that the board is embedded between two adjacent partition blocks 3036. In addition to the suction force of the suction cup 3035 above, the board also has the friction force of the partition blocks 3036 on its side, making the board less likely to fall or move during the movement. A suction connection port 30351 is provided on the top of the suction cup 3035.

[0058] The suction control mechanism 304 includes a suction conversion component 3041, which has a suction inlet 30411. Several suction cup interfaces 30412 are located on the side of the suction conversion component 3041 away from the suction inlet 30411. An external fan is connected to the suction inlet 30411. The suction cup interfaces 30412 are connected to the suction connection ports 30351 of the suction cups 3035 via pipes. A suction control cylinder 3042 is located on the side of the suction conversion component 3041. The cylinder extension shaft of the suction control cylinder 3042 is connected to a suction control plate 3043. The suction control plate 3043 is slidably inserted into the suction conversion component 3041. The suction control plate 3043 is positioned between the suction inlet 30411 and the suction cup interfaces 30412. When suction is required on the material, the suction control plate 3043... Under the control of the suction control cylinder 3042, the suction conversion component 3041 is pulled out. At this time, the suction inlet 30411 and the suction cup interface 30412 are the same, and the suction cup 3035 has adsorption capacity. When the suction cup 3035 moves above the storage lifting component 305 and the board needs to be unloaded, the suction control plate 3043 is pushed into the suction conversion component 3041 under the control of the suction control cylinder 3042. At this time, the suction inlet 30411 and the suction cup interface 30412 are separated, and the suction cup 3035 does not have adsorption capacity. The board is unloaded. The lower surface of the suction cup 305 has several adsorption holes. The adsorption holes are connected to the upper air outlet in an internal hollow manner, which can effectively discharge the wood chips, dust and other foreign objects sucked up by the suction cup from the board, thereby improving the adsorption force of the suction cup on the board and enhancing the actual use effect.

[0059] The lifting mechanism 302 includes a lifting base 3021, a lifting cylinder 3022 is provided in the middle of the lifting base 3021, and lifting slide rails 3023 are provided at both ends of the lifting cylinder 3022. The lifting slide rails 3023 are slidably connected to the rotating base 3024. The cylinder push-out shaft of the lifting cylinder 3022 is connected to the rotating base 3024. Therefore, the rotating base 3024 can be raised and lowered relative to the lifting base 3021. The rotating base 3024 is provided with a rotating bearing 3028, which is rotatably connected to a rotating component 3029. A rotating gear 30291 is provided at the upper end of the rotating component 3029, and a suction cup mounting bracket 30292 is provided at the lower end of the rotating component 3029. A rotary drive cylinder 3026 is provided on the rotary base 3024. The rotary drive cylinder 3026 is connected to a rotary drive rack 3027. The rotary drive rack 3027 meshes with a rotary gear 30291. Therefore, when the rotary drive rack 3027 moves under the drive of the rotary drive cylinder 3026, it can drive the rotating component 3029 to rotate. Thus, the suction cup mounting bracket 30292 can rotate relative to the lifting mechanism 302. Therefore, the rotary material handling robot 3 can realize the staggered placement of the plates.

[0060] The gantry frame 301 includes a slide rail 3011 and a rack 3012. The slide rail 3011 is slidably connected to the lifting mechanism 302. The lifting mechanism 302 includes a moving motor 3025. The moving motor 3025 is connected to a moving gear 30251. The moving gear 30251 meshes with the rack 3012. Driven by the moving motor 3025, the suction cup mechanism 303 can move relative to the gantry frame 301.

[0061] A quantitative alignment power assembly 404 has a quantitative blocking mechanism 403 at one end, a quantitative alignment adjustment assembly 405 on its side, and a quantitative conveying assembly 402 below it. The quantitative alignment power assembly 404 includes several alignment shafts 40433, and the quantitative conveying assembly 402 includes several quantitative conveying chains 4025. The alignment shafts 40433 and the quantitative conveying chains 4025 are staggered. This device aligns two perpendicular sides of the sheet material using the quantitative blocking mechanism 403 and the quantitative alignment adjustment assembly 405 to achieve the purpose of neatly aligning the sheet material. The rolling quantitative conveying chains 4025 drive the sheet material towards the quantitative blocking mechanism 403 for alignment, while the alignment shafts 40433 drive the sheet material towards the quantitative alignment adjustment assembly 405. The power source for this driving method is located below the sheet material, in contact with its entire bottom surface. Therefore, it can align sheet materials regardless of their length, making it widely applicable and adaptable.

[0062] The quantitative alignment power assembly 404 includes a power assembly lifting mechanism 4041, which includes a power lifting base 40411 connected to the alignment frame 401. A power lifting cylinder 40412 is mounted on the power lifting base 40411. The cylinder rod extension end of the power lifting cylinder 40412 is connected to a lifting cylinder connecting plate 40413, which is connected to the lower end of the alignment rotating shaft assembly 4043. Component 4043 includes a shaft assembly base 40431, with a plurality of shaft bearings 40432 connected to both ends of the shaft assembly base 40431. The plurality of shaft bearings 40432 are rotatably connected to an aligned shaft 40433. One end of the aligned shaft 40433 is provided with a belt connecting groove 404331. One end of the shaft assembly base 40431 is connected to a rotating component 4042, which includes a rotating bearing seat 40424. The rotating bearing seat 40424 is rotatably connected to a rotating shaft 40433. A rotating spindle 40423 is connected to a rotating chain 40422, which in turn is connected to a rotating motor 40421. Several rotating circular belts 40425 are connected to the rotating spindle 40423. The other end of each rotating circular belt 40425 is connected to an alignment shaft 40433. The rotating circular belts 40425 are fitted into belt connecting grooves 404331. The rotating motor 40421 drives the rotating spindle 40423 to rotate via the rotating chain 40422. Multiple rotating circular belts 40425 are connected to the main spindle 40423. Therefore, the rotation of the main spindle 40423 simultaneously drives the multiple rotating circular belts 40425 to rotate, and the rotating circular belts 40425 simultaneously drive the multiple alignment shafts 40433 to rotate. The plates to be aligned laterally are placed on the multiple alignment shafts 40433. Therefore, multiple positions under the plates are in contact with the rotating alignment shafts 40433. Regardless of the length of the plates, they can be rolled and pushed to one side by the alignment shafts 40433 for positioning.

[0063] The quantitative blocking mechanism 403 includes a quantitative blocking base 4031, which is connected to the alignment frame 401. A blocking lifting cylinder 4032 is connected to the quantitative blocking base 4031. The cylinder extension shaft of the blocking lifting cylinder 4032 is connected to a blocking lifting connector 4033. The upper end of the blocking lifting connector 4033 is connected to a blocking lifting rod 4034. Several quantitative blocking plates 4035 are connected to the blocking lifting rod 4034. The quantitative blocking plates 4035 intersect with the quantitative conveying chain 4025. The quantitative blocking plate 4035 is staggered and can move up and down relative to the quantitative conveying component 402. When the quantitative blocking plate 4035 is raised, it is higher than the upper surface of the quantitative conveying chain 4025. When the quantitative blocking plate 4035 is lowered, it is lower than the upper surface of the quantitative conveying chain 4025. Therefore, when the quantitative blocking plate 4035 is raised, it can block the plate above the quantitative conveying chain 4025. When the quantitative blocking plate 4035 is lowered, the plate above the quantitative conveying chain 4025 will be conveyed to the next process.

[0064] The quantitative alignment adjustment component 405 includes a quantitative alignment cylinder seat 4051, a quantitative alignment cylinder 4052 connected to the quantitative alignment cylinder seat 4051, and a quantitative alignment baffle 4053 connected to the push rod of the quantitative alignment cylinder 4052. The push or retraction of the quantitative alignment baffle 4053 determines the alignment position of the plate. Therefore, the quantitative alignment adjustment component 405 can be used to adjust the relative position of the alignment direction of the plate.

[0065] The quantitative conveying assembly 402 includes a quantitative conveying motor 4021, which is connected to a quantitative motor chain 4022. The quantitative motor chain 4022 is connected to a quantitative conveying drive shaft 4023. The quantitative conveying drive shaft 4023 is connected to several quantitative conveying chains 4025. The quantitative conveying chains 4025 are connected to several quantitative conveying driven shafts 4024. Therefore, the quantitative conveying assembly 402 can convey a quantitative amount of material and align it with the quantitative blocking mechanism 403.

[0066] An alignment component 503 is provided on one side of the interval blocking mechanism 502, and a conveying component 501 is inserted above the interval blocking mechanism 502. The interval blocking mechanism 502 has multiple blocking components 5023 arranged at intervals and capable of being raised and lowered in batches. When the board is conveyed from the conveying component 501, the blocking components 5023 of the interval blocking mechanism 502 rise in batches to block the gradually conveyed board in batches, so that there is a certain gap between the board. Then, the alignment push plate 5033 of the alignment component 503 pushes out to push one side of the board to align, so that the board forms an arrangement with one side aligned and gaps between each board. This allows for a certain airflow space between the boards after they are stacked, which is conducive to the evaporation of moisture from the board.

[0067] The interval blocking mechanism 502 includes a plurality of blocking members 5023, which are arranged at intervals. The blocking members 5023 can move up and down in a direction perpendicular to the conveyor chain 5014. When the blocking member 5023 is lowered, the plate can pass through. When the blocking member 5023 is raised, it will block the plate. The blocking component 5023 includes a blocking strip 50231, and the blocking strip 50231 is vertically fixed with a reinforcing rib 50232. When the sheet material is conveyed by the conveying assembly 501, it will be blocked by the blocking component 5023, which will have a certain impact force on the blocking component 5023. The reinforcing rib 50232 makes the blocking component 5023 have a certain blocking effect on the impact force, making the blocking strip 50231 less prone to deformation. The conveying assembly 501 includes several conveying chains 5014, which are inserted between the gaps of two blocking strips 50231. Therefore, the movement of the conveying chain 5014 will not be affected when the blocking component 5023 rises and falls. After the blocking component 5023 blocks the previous batch of sheet material, the subsequent batch of sheet material can still be continuously transported.

[0068] The interval blocking mechanism 502 includes a blocking base 5021, which is connected to the interval alignment frame 504. Several blocking cylinders 5022 are provided on the blocking base 5021. The push rod of the blocking cylinder 5022 is connected to the blocking member 5023. Therefore, under the control of the multiple blocking cylinders 5022, the blocking member 5023 can perform lifting and lowering actions in batches.

[0069] The alignment assembly 503 includes an alignment base 5031, which is connected to the side of the spaced alignment frame 504. An alignment cylinder 5032 is connected to the alignment base 5031, and the push rod of the alignment cylinder 5032 is connected to an alignment push plate 5033. The alignment push plate 5033 is parallel to the conveyor chain 5014, and the bottom end of the alignment push plate 5033 is higher than the top of the conveyor chain 5014. Therefore, when the alignment push plate 5033 is pushed out, it can flatten the plate located above the conveyor chain 5014 without impacting the conveyor chain 5014.

[0070] The conveying assembly 501 includes a conveying motor 5011, which is connected to a motor chain 5012. The motor chain 5012 is connected to a conveying drive shaft 5013, which is connected to a conveying chain 5014. The conveying chain 5014 is connected to several conveying driven shafts 5015. The conveying motor 5011 drives the conveying drive shaft 5013 to rotate, thereby driving the conveying chain 5014 to rotate. As a result, the plate material located above the conveying chain 5014 is moved. The several conveying driven shafts 5015 are set up to rotate in conjunction with the plate material, while also supporting the plate material, so that the conveying chain 5014 will not be deformed by the weight of the plate material.

[0071] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
