Description

Technical Field

[0001] This invention relates to the field of stacking and packaging technology for block materials, and more specifically to a packaging method for block materials and a system for applying this method. Background Technology

[0002] Block materials refer to solid materials with a certain shape and size in three-dimensional space. These materials typically have block, square, rectangular, or other regular or irregular geometric shapes, and their dimensions can vary from tiny to enormous. Block materials can be natural, such as stone, wood, and rock, or man-made, such as metal, plastic, concrete, plaster, ceramics, and glass. Block materials have wide applications in various fields, and different types of block materials have different properties and uses.

[0003] Before handling and transportation, block materials need to be stacked in multiple layers. Simply bundling and packaging the stacked materials is insufficient for long-term transport and handling; the upper and lower layers are prone to separation and tipping, leading to stack collapse, material damage, or personal injury. This not only affects transportation efficiency but also increases the time and cost of loading, unloading, and handling. Currently, when stacking block materials, a mesh or film is typically placed between the upper and lower layers to increase the traction between adjacent blocks, making the entire stack more stable and meeting the transportation requirements of block materials.

[0004] Existing block material production lines can only cover and stack block materials at a single workstation when covering them with mesh. This results in low work efficiency, large floor space requirements, high operating costs, and limited applicability. They also cannot cover block materials of different heights. Furthermore, the material rolls used by the covering machines in the block material production line are all located at the top of the equipment, making it inconvenient to change the rolls. This requires workers to climb to the top, and the top-mounted rolls shift the center of gravity of the equipment, affecting its operational stability. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a method for packaging block materials and a system for applying this method.

[0006] To achieve the above objectives, the technical solution of the present invention is: a method for packaging block materials, comprising the following steps:

The swing arm mechanism includes a swing arm frame and a covering power mechanism disposed on the transverse base. The covering power mechanism controls the covering net within the swing arm frame to perform arc-shaped movements.

[0031] Furthermore, the clamping mechanism includes an upper clamping mechanism and a lower clamping mechanism. The upper clamping mechanism is movably disposed within the swing arm frame, and the lower clamping mechanism is fixedly disposed on the support arm.

[0052] To better understand the purpose, structure, and function of this invention, the following detailed description, in conjunction with the accompanying drawings, provides a method for packaging block materials and a system for applying this method.

[0053] like Figures 1 to 12 As shown, a method for packaging block materials includes the following steps:

[0054] S1. Transport a predetermined number of pallets to the designated location on the conveying system;

[0055] S101, Horizontally lift and stack pallets;

[0056] S102. Restrict the position of the second-layer pallet to prevent the second-layer and above pallets from falling.

[0057] S103. Lower the first layer pallet onto the conveyor system and transport it to the designated location with the conveyor system;

[0058] S104. Repeat steps S101 to S103 until the specified number of pallets are removed.

[0059] S2. Place the predetermined number of layered block materials onto the corresponding trays;

[0060] S3. Lay the mesh cover flat on top of the block material;

[0061] S301. Clamp the covering net from the bottom of the covering machine and tighten it;

[0062] S302. Cut the taut netting at the bottom of the taut netting;

[0063] S303, Move the covering net to align it with the block material to be covered, and rotate the covering net to cover the aligned block material;

[0064] S304. Repeat steps S301 to S303 until the block material at the same height is covered.

[0065] S4. Place a predetermined number of layered block materials on the corresponding block materials;

[0066] S5. Repeat steps S3 and S4 until the preset number of stacking layers of the block material is reached, so that a mesh is laid between adjacent layers of block material.

[0067] S6. Packaging;

[0068] Step S6 includes horizontal packing and vertical packing.

[0069] The horizontal packing step includes packing at least one layer of block material in a horizontal ring shape;

[0070] The vertical packing steps include:

[0071] Vertically pack the opposite sides of the stacked block materials;

[0072] Rotate the stacked block materials horizontally by 90 degrees.

[0073] Pack the other two sides of the stacked block materials vertically.

[0074] In step S303, the position of the top of the covering net can be adjusted up and down, and the direction of the covering net is perpendicular to the direction of conveying the block material.

[0075] The covering machine used in step S3 includes a base track mechanism 61 and a swing arm covering mechanism 62 that can move on the base track mechanism 61. The base track mechanism 61 is parallel to the conveying direction of the block material. The swing arm covering mechanism 62 includes a supporting discharge mechanism 622 for placing the discharge roll 6228, a clamping mold mechanism 623 for clamping and tightening the covering net, a moving cutter mechanism 624 for cutting the covering net, a swing arm mechanism 625 for tilting and covering the block material, and a transverse base 621. The supporting discharge mechanism 622 is disposed on the transverse base 621 at the bottom of the swing arm covering mechanism 62. The swing arm mechanism 625 includes a swing arm frame and a covering power mechanism disposed on the transverse base 621. The covering power mechanism controls the covering net inside the swing arm frame to make arc-shaped movements. The clamping mold mechanism 623 includes an upper clamping mold mechanism 626 and a lower clamping mold mechanism 627. The upper clamping mold mechanism 626 is movably disposed inside the swing arm frame, and the lower clamping mold mechanism 627 is fixedly disposed on the support arm. The support arm is disposed on the transverse base 621.

[0076] The base track mechanism 61 includes a mounting base plate 612, a swing arm covering mechanism 62 is provided above the mounting base plate 612, a drive mechanism 613 is provided on one side of the mounting base plate 612, and a travel guide rail 611 is provided below the mounting base plate 612. The drive mechanism 613 includes a drive motor and a gear provided at the output end of the drive motor. A rack that meshes with the gear is provided inside the travel guide rail 611. The drive mechanism 613 drives the mounting base plate 612 to move on the travel guide rail 611.

[0077] The swing arm covering mechanism 62 includes a transverse base 621 mounted on a mounting base plate 612. A support arm 6245 is located at the top center of the transverse base 621. A support discharge mechanism 622 is located on one side of the support arm 6245, which supports the material roll 6228 and guides the covering mesh inside the material roll 6228. A swing arm mechanism 625 is located on the other side of the support arm 6245, which is used to cover the block material with the covering mesh. A clamping mechanism 623 is provided at the top. The clamping mechanism 623 is used to clamp out and tighten the covering mesh. The clamping mechanism 623 includes a lower clamping mechanism 627 and an upper clamping mechanism 626. The upper clamping mechanism 626 is movably arranged in the swing arm mechanism 625. The lower clamping mechanism 627 is arranged on the top of the support arm 6245. A movable cutting mechanism 624 is provided on one side of the lower clamping mechanism 627. The movable cutting mechanism 624 can cut the covering mesh tightened by the upper clamping mechanism 626 and the lower clamping mechanism 627.

[0078] The material feeding mechanism 622 includes a material roll support frame disposed on one side of the support arm 6245. The material roll support frame includes a roller seat 6225 fixedly disposed above the transverse base 621. The roller seat 6225 has an overall arc-shaped structure. Two unpowered rollers 6221 are disposed inside the roller seat 6225. The unpowered rollers 6221 are respectively disposed at the higher ends of the arc-shaped structure of the roller seat 6225, and there is a certain distance between the two unpowered rollers 6221. A material roll 6228 is placed between the two unpowered rollers 6221. The material roll 6228 is centrally disposed on the unpowered rollers 6221. One of the unpowered rollers is... Limiting blocks 6222 are movably provided at both ends of the force roller 6221. The distance between the limiting blocks 6222 and the material roll 6228 is adjusted according to the width of the material roll 6228, so that the limiting blocks 6222 limit the material roll 6228 to the left and right. Another unpowered roller 6221 is provided with a brake assembly, which includes a base belt 226 and a spring connected to the base belt 226. The base belt 226 holds the unpowered roller 221 tightly under the action of the spring. When the film clamping action stops, the unpowered roller 221 stops rotating immediately under the action of the base belt 226 to prevent the material roll 6228 from being over-extruded due to inertia. A lower guide roller 6223 and a pressure roller 6224 are positioned at the midpoint between the support arms 6245. The lower guide roller 6223 is at a higher horizontal level than the pressure roller 6224. The lower guide roller 6223 and pressure roller 6224 are adjacent to each other with a gap between them. An upper guide roller 6227 is positioned above the pressure roller 6224 at the upper part between the support arms 6245. The upper guide roller 6227 guides the covering net, preventing it from dangling in mid-air when exiting the material roll 6228, ensuring smooth exit of the covering net. The covering net in the material roll 6228 passes through the gap between the lower guide roller 6223 and pressure roller 6224, and enters the lower clamping mechanism 627 via the upper guide roller 6227. This bottom-discharge method facilitates the replacement of the material roll 6228 by workers, avoids the dangers of working at height, and ensures the personal safety of workers.

[0079] Both the upper clamping mechanism 626 and the lower clamping mechanism 627 include a static pressure plate 6234, a dynamic pressure plate 6235, and a clamping cylinder 6233 for controlling the movement of the dynamic pressure plate 6235. Several clamping blocks 6237 are provided on both the static pressure plate 6234 and the dynamic pressure plate 6235. The clamping blocks 6237 are arranged opposite to each other between the upper and lower dynamic pressure plates 6235 and the upper and lower static pressure plates 6234. The clamping blocks 6237 in the upper clamping mechanism 626 and the clamping blocks 6237 in the lower clamping mechanism 627 are... The clamping blocks 6237 are staggered, with anti-slip pads 6236 affixed to them. These pads increase the friction between the static pressure plate 6234 and the dynamic pressure plate 6235, facilitating the clamping of the covering film exiting the material roll 6228. The clamping cylinder 6233 in the upper clamping mechanism 626 is positioned on the back of the swing arm in the tilting direction to prevent it from colliding with and damaging the block material during covering. The coordinated clamping of the upper and lower clamping mechanisms 626 and 627 improves the success rate of clamping and prevents incomplete clamping or film detachment.

[0080] The upper clamping mechanism 626 also includes an upper clamping mechanism connector 6231 and a transmission mechanism 6232. The upper clamping mechanism connector 6231 connects the static pressure plate 6234 to the swing arm frame. The swing arm frame includes a left swing arm 6254 and a right swing arm 6255. The transmission mechanism 6232 is respectively installed in the left swing arm 6254 and the right swing arm 6255. A discharge power mechanism 6239 is provided on one side of the swing arm frame. A material pulling drive shaft 6238 is provided at the bottom between the left swing arm 6254 and the right swing arm 6255. The discharge power mechanism 6239 controls the rotation of the material pulling drive shaft 6238. The material pulling drive shaft 6238 is connected to the transmission mechanism 6232.

[0081] The transmission mechanism 6232 includes gears at both ends of the material pulling drive shaft 6238, which are respectively installed inside the left swing arm 6254 and the right swing arm 6255. The top of the left swing arm 6254 and the right swing arm 6255 are equipped with gears corresponding to the gears at both ends of the material pulling drive shaft 6238. The upper and lower gears are connected together by a synchronous belt. The gears at both ends of the material pulling drive shaft 6238 are the same size. The gears on both sides of the upper part of the transmission mechanism 6232 are the same size. The left and right synchronous belts move synchronously under the drive of the motor teeth in the discharge power mechanism 6239. An upper clamping mechanism 626 is provided between the synchronous belts. The upper clamping mechanism 626 is equipped with upper clamping mechanism connectors 6231 at both ends. The upper clamping mechanism connectors 6231 are fixedly installed on one side of the synchronous belts. The left swing arm 6254 and the right swing arm 6255 are equipped with guide rails. The upper clamping mechanism connectors 6231 can slide up and down along the guide rails inside the left swing arm 6254 and the right swing arm 6255. When the discharge power mechanism 6239 drives the material pulling drive shaft 6238 to rotate, the material pulling drive shaft 6238 drives the gears at both ends to rotate, which in turn drives the synchronous belt that cooperates with the gears to move. The upper clamping mechanism 626 on the synchronous belt moves along the guide rails in the left swing arm 6254 and the right swing arm 6255 with the synchronous belt, and finally drives the upper clamping mechanism 626 to move.

[0082] The movable cutting mechanism 624 includes a cutting power mechanism 6241 disposed on one side of the lower clamping mechanism 627. The cutting power mechanism 6241 is a long-stroke cylinder. The extension end of the cylinder is provided with a cutting connector 6244. The other end of the cutting connector 6244 is connected to a cutting blade 6243. A guide rail 6242 is disposed on one side of the cutting power mechanism 6241. The cutting connector 6244 is movably disposed on the guide rail 6242. When the cutting power mechanism 6241 is activated, it controls the cutting connector 6244 to reciprocate along the guide rail 6242. The cutting blade 6243 can cut the covering mesh that has been tightened by the upper clamping mechanism 626 and the lower clamping mechanism 627.

[0083] The swing arm mechanism 625 includes a swing arm frame and a covering power mechanism for controlling the rotation of the swing arm frame. The swing arm frame includes a left swing arm 6254 and a right swing arm 6255. The covering power mechanism includes a swing arm power mechanism 6251. The output gear of the swing arm power mechanism 6251 is meshed with a transmission gear 252. The transmission gear 252 is mounted on a rotary shaft 253. The two ends of the rotary shaft 253 are respectively connected to the left swing arm 254 and the right swing arm 255. The swing arm power mechanism 6251 drives the left swing arm 254 and the right swing arm 255 to perform circular motion around the rotary shaft 253.

[0084] The material roll 6228 can be either a mesh or a film, as long as the material exported from the material roll 6228 covers the block material and can increase the traction between the layers of the block material.

[0085] A packaging system for block materials includes a feeding conveyor 1, a depalletizing conveyor 2, a pallet waiting conveyor 4, a palletizing station conveyor 5, a horizontal packaging conveyor 7, a moving rotary conveyor 10, and a material unloading buffer conveyor 11 arranged sequentially. The feeding conveyor 1, depalletizing conveyor 2, pallet waiting conveyor 4, palletizing station conveyor 5, horizontal packaging conveyor 7, moving rotary conveyor 10, and material unloading buffer conveyor 11 are all straight-plate chain conveyors. A pallet depalletizer 3 is arranged above the depalletizing conveyor 2. A netting machine 6 is arranged on one side of the palletizing station conveyor 5, and a palletizer 12 is arranged on the other side of the palletizing station conveyor 5. A horizontal packaging machine 8 is arranged on one side of the horizontal packaging conveyor 7, and a vertical packaging machine 9 is arranged on one side of the moving rotary conveyor 10. Specifically, it can be a gantry vertical packaging machine with corner protectors. The positions of the horizontal packing conveyor 7 and the mobile rotary conveyor 10 can be interchanged, allowing for vertical packing of stacked block materials followed by horizontal packing, and also enabling six-sided packing of block materials. The covering machine 6 includes a base track mechanism 61 and a swing arm covering mechanism 62. The swing arm covering mechanism 62 can move on the base track mechanism 61 and can cover the block materials with a net.

[0086] The equipment at the forefront of the production line is the feeding conveyor 1, used for pallet stacking and feeding. It includes forklift loading / unloading positions and protective structures. Manual loading is used; forklifts place pallet stacks onto the feeding conveyor 1. Once the feeding conveyor starts moving and the photoelectric sensor detects the pallet stack, the depalletizing conveyor 2 begins transporting the pallet stack to the appropriate position on the pallet depalletizer 3, awaiting its depalletizing. The pallet depalletizer 3 depalletizes several pallets at a time according to production needs, and these pallets sequentially pass through the pallet waiting conveyor 4 and the pallet stacking station conveyor 5. The pallet stacking station conveyor 5 has the same number of stations as the number of pallets depalletized by the pallet depalletizer 3. Under the monitoring of the photoelectric sensor, several pallets sequentially stop at their corresponding positions, awaiting the stacking of block materials. The palletizer 12, placed opposite the screen covering machine 6, performs the stacking. Figures 10 to 12As shown, the robotic arm of the palletizer 12 is equipped with several robotic grippers. These grippers pick up block materials and move them above the pallets. The grippers move along the guide rails of the robotic arm. Based on the number of pallets, the block materials picked up by the grippers are divided into equal portions equal to the number of pallets. After moving, the grippers press adjacent blocks of material within the same group together. The robotic arm then controls the blocks to move downwards, placing the pressed blocks of the same group onto the corresponding pallets. The robotic arm can pick up multiple groups of block materials and place them onto the corresponding pallets at once, or it can pick up only one group of block materials at a time and place it onto the corresponding pallet, performing multiple operations. Both this simultaneous multi-group picking and multiple single-group picking operations can meet the requirements for stacking block materials on pallets. After the block material is picked up, the covering machine 6 starts working. The swing arm covering mechanism 62 moves back and forth on the base track mechanism 61 to cover the block material at different work stations. After the covering work of block materials at multiple work stations at the same height is completed, the robotic arm of the palletizer 12 stacks the materials again. The covering machine 6 repeats the covering work. After the number of layers of block material stacking reaches the preset number, it is transported to the horizontal packing machine 8 by the horizontal packing conveyor and waits for the horizontal packing machine 8 to pack it. At this time, the pallet depalletizer 3 performs pallet depalletizing work again.

[0087] The horizontal baler 8 sequentially straps the block material stack from top to bottom, controlling the number of strapping channels as needed. After horizontal strapping, the block material stack is conveyed to the mobile rotary conveyor 10, which is an RGV mobile trolley. Under program control and monitoring, it moves to the working position of the vertical baler 9, where it performs longitudinal strapping, again controlling the number of strapping channels as needed. After completion, the RGV mobile trolley moves away from the vertical baler 9 and rotates 90° without interference, completing the direction change. It then conveys the material back to the working position of the vertical baler 9 for the remaining two sides of longitudinal strapping. This completes the six-sided strapping of the block material. While the gantry strapping is being performed, the horizontal baler can also operate simultaneously. After all six sides are strapped, the block material stack is conveyed to the unloading buffer conveyor 11, awaiting manual unloading.

[0088] The pallet depalletizer 3 includes a lifting mechanism located in the middle of the depalletizer 2 and limiting mechanisms located on both sides of the depalletizer 2. The lifting mechanism controls the lifting and lowering of the pallet stack, and the limiting mechanisms limit the position of the second layer of pallets. The lifting mechanism includes a lifting plate and a lifting cylinder located below the lifting plate. The lifting cylinder controls the lifting plate to move up and down, thereby controlling the pallet stack to move up and down. The limiting mechanism includes a limiting plate located on a rotating shaft. Rotary cylinders that control the rotation of the rotating shaft are located on both sides of the rotating shaft.

[0089] The pallet stacks conveyed to the depalletizing conveyor 2 are depalletized within the pallet depalletizer 3. A lifting cylinder within the depalletizer 3 controls the lifting plate to rise, causing the pallet stack to leave the depalletizing conveyor 2. A rotating cylinder in the limiting mechanism controls the rotating shaft to rotate, thereby controlling the limiting plate to rotate into the pallet stack. The limiting plate inserts into the gap between the second layer of pallets. At this point, the lifting cylinder retracts, causing the lifting plate to move downwards. The pallets at the bottom of the lifting plate then fall onto the depalletizing conveyor 2 and are conveyed to the pallet waiting conveyor 4. This process of depalletizing is repeated until the required number of pallets are removed.

[0090] Before using the covering machine 6, the material roll 6228 needs to be installed on the support discharge mechanism 622. The operator first moves the limit blocks 6222 on the unpowered roller 6221, which are equipped with limit blocks 6222, to both sides of the roller. Then, the material roll 6228 is placed between the two unpowered rollers 6221 on the roller seat 6225, with the material roll 6228 centered. The position of the limit blocks 6222 is adjusted so that they are close to both sides of the material roll 6228. The movable limit blocks 6222 are fixed on both sides to accommodate material rolls 6228 of different lengths. Finally, the covering mesh is pulled out from the material roll 6228. The covering net passes through the gap between the lower guide roller 6223 and the pressure roller 6224 in the transverse base 621, and vertically upwards through the upper guide roller 6227 into the lower clamping mechanism 627. The covering net adheres tightly to the upper guide roller 6227. The moving pressure plate 6235 in the lower clamping mechanism 627 is separated from the static pressure plate 6234 under the action of the clamping cylinder 6233. The covering net passes through the gap between the moving pressure plate 6235 and the static pressure plate 6234. The clamping cylinder 6233 controls the moving pressure plate 6235 to approach the static pressure plate 6234, so that the moving pressure plate 6235 and the static pressure plate 6234 clamp the covering net. At this time, the preparation work of the covering machine is completed.

[0091] The pallet waiting conveyor 4 transports the pallets disassembled by the pallet depalletizer 3 to the corresponding workstations on the palletizing station conveyor 5. The palletizer 12 on one side of the palletizing station conveyor uses a robotic arm to grab the block material onto the corresponding pallet on the palletizing station conveyor 5. The covering machine 6 starts working, and the discharge power mechanism 6239 starts, driving the material pulling drive shaft 6238 to rotate through the transmission belt. The rotation of the material pulling drive shaft 6238 drives the transmission mechanism 6232 to work. The transmission mechanism 6232 drives the upper clamping mechanism 626 to move downward. The dynamic pressure plate 6235 in the upper clamping mechanism 626 moves away from the static pressure plate 6234 under the action of the clamping cylinder 6233. When the upper clamping mechanism 626 approaches the lower clamping mechanism 627, the upper clamping mechanism 626... The moving pressure plate 6235 moves towards the static pressure plate 6234 under the action of the clamping cylinder 6233. The moving pressure plate 6235 and the static pressure plate 6234 in the upper clamping mechanism 626 cooperate to clamp the covering mesh in the lower clamping mechanism 627. The clamping blocks 6237 at the bottom of the moving pressure plate 6235 and the static pressure plate 6234 in the upper clamping mechanism 626 are staggered with the clamping blocks 6237 at the top of the moving pressure plate 6235 and the static pressure plate 6234 in the lower clamping mechanism 627. The clamping block 6237 enters the gap between two adjacent clamping blocks 6237 in the lower clamping mechanism 627. While the upper clamping mechanism 626 clamps the covering mesh, the clamping cylinder 6233 of the lower clamping mechanism 627 controls the dynamic pressure plate 6235 to separate from the static pressure plate 6234, releasing the covering mesh. The discharge power mechanism 6239 drives the transmission mechanism 6232 to move upwards. The upper clamping mechanism 626 pulls out the covering mesh from the material roll 6228 and moves it upwards together. When the upper clamping mechanism 626 moves... When the material reaches the designated position, the discharge power mechanism 6239 stops working, and the dynamic pressure plate 6235 and static pressure plate 6234 in the lower clamping mechanism 627 clamp the covering mesh again. The upper clamping mechanism 626 and the lower clamping mechanism 627 work together to pull the covering mesh tight. The unpowered roller 6221 with the sheet base belt 6226 in the roller seat 6225 stops rotating under the action of the sheet base belt 6226. The sheet base belt 6226 hugs the unpowered roller 6221 to prevent the material roll 6228 from being over-discharged.

[0092] The cutting blade connector 6244 in the moving cutting blade mechanism 624 moves along the guide rail 6242, and the cutting blade 6243 on the cutting blade connector 6244 cuts the taut covering mesh. The horizontal height of the cutting blade 6243 is slightly higher than the height of the lower clamping mechanism 627, and the cutting blade 6243 performs horizontal cutting on the covering mesh.

[0093] After the covering mesh is cut, the upper clamping mechanism 626 moves downward a certain distance under the control of the discharge power mechanism 6239. When one layer of block material is stacked, it moves downward a certain distance. As the height of the block material stack increases, the downward distance of the upper clamping mechanism 626 will gradually become shorter. The downward distance of the upper clamping mechanism 626 only needs to ensure that the horizontal height of the top of the covering mesh is slightly lower than the horizontal height of the top of the block material, so as to ensure that the upper clamping mechanism 626 is above the block material when tilted.

[0094] The drive mechanism 613 in the base track mechanism 61 is activated, and the drive mechanism 613 drives the mounting base plate 612 to move to a suitable position on the walking guide rail 611, so that the swing arm covering mechanism 62 on the mounting base plate 612 is aligned with the block material to be covered, and the left swing arm 6254 and the right swing arm 6255 are located on the left and right sides of the block material.

[0095] When the swing arm mechanism 625's swing arm power mechanism 6251 is activated, the motor in the swing arm power mechanism 6251 controls the gear to rotate. The gear in the swing arm power mechanism 6251 meshes with the transmission gear 6252, driving the transmission gear 6252 to rotate. The transmission gear 6252 is fixedly mounted on the rotary shaft 6253, which rotates together with the transmission gear 6252. The two ends of the rotary shaft 6253 are connected to the left swing arm 6254 and the right swing arm 6255 respectively through expansion sleeves. The left swing arm 6254 and the right swing arm 6255 perform circular arc motion around the rotary shaft 6253. The rotation angle of the left swing arm 6254 and the right swing arm 6255 is controlled by a servo motor. When the left swing arm... When 6254 and the right swing arm 6255 rotate to the appropriate angle, the swing arm power mechanism 6251 stops working. The upper clamping mechanism connector 6231 moves towards the top of the swing arm mechanism 625 along the direction of the transmission mechanism 6232. The covering net clamped by the upper clamping mechanism 626 covers the top of the block material. When the upper clamping mechanism connector 6231 moves to the edge of the block material, the photoelectric switches on both sides of the upper clamping mechanism connector 6231 detect the signal and feed it back to the clamping cylinder 6233 in the upper clamping mechanism 626. The clamping cylinder 6233 controls the dynamic pressure plate 6235 to move away from the static pressure plate 6234 and release the covering net, so that the covering net completely covers the block material, completing the covering of the block material. Thus, one covering operation is completed.

[0096] After completing the covering work for a group of block materials, the swing arm covering mechanism 62, driven by the drive mechanism 613, moves linearly along the travel guide rail 611 to the next block material station and repeats the covering action until all block materials on the palletizing station conveyor 5 are covered. The number of covering stations for block materials at the same height is directly proportional to the length of the travel guide rail 611 in the base track mechanism 61. The longer the travel guide rail 611, the more covering stations there are for block materials, thus completing multi-station covering work.

[0097] After all the block materials in the same layer have been covered with netting, the robotic arm simultaneously or sequentially grabs the block materials to be stacked and places them directly above the netted block materials. Netting is added between adjacent layers of block materials. Netting can increase the traction between the block materials, making the block materials hold each other more stably and increasing the stability of the entire block material stack, thereby better meeting the requirements of loading, unloading and transportation.

[0098] Repeat the process of covering the block material with mesh and stacking the block material until the block material is stacked to the required number of layers and height. At this point, the stacking of the block material is complete.

[0099] Horizontal strapping machine 8 and vertical strapping machine 9 are commonly used existing strapping equipment, and their specific structures will not be discussed here.

[0100] The block material of this invention can be a variety of materials such as gypsum, cement, wood, ceramics, and glass, specifically gypsum blocks, gypsum boards, cement modules, etc.
