Description

Technical Field

[0001] This invention relates to the field of stacking equipment technology, and specifically to an automatic stacking equipment for wood-plastic composite boards. Background Technology

[0002] Wood-plastic composite boards are widely used in building decoration, logistics packaging and other fields due to their advantages such as environmental protection, corrosion resistance and easy processing. Stacking and packaging, as the final process of wood-plastic composite board production, needs to achieve the core goal of neat stacking and stable packaging. It is necessary to ensure the integrity of the boards during transportation and also take into account the efficiency of operation to adapt to large-scale production. Currently, the production capacity of the wood-plastic composite board industry continues to expand, but the many defects of the traditional stacking and packaging model have become a key bottleneck restricting industrial upgrading.

[0003] The traditional wood-plastic composite board stacking and packaging process has the following shortcomings: Firstly, the process involves a high degree of manual intervention and is inefficient. After the wood-plastic composite boards are cut, they need to be manually transported to the stacking platform and stacked piece by piece. The waste generated from cutting is collected and discarded separately. After stacking, the boards are manually tied and reinforced with wire or packing straps. The entire process relies on manpower, and each batch of stacking takes a long time. Furthermore, manual stacking is prone to skewing, which increases the subsequent handling costs.

[0004] Secondly, the stacking stability is poor and the protection is insufficient; traditional packing straps can only be tied horizontally or vertically, resulting in poor overall integrity of the stack and easy disintegration during transportation; at the same time, the slitting waste is directly discarded, which not only wastes resources but also increases the cost of environmental treatment, which is contrary to the concept of green production.

The feeding components 820 extending into the bottom of both sides of the material cylinder 801 are mounted on the bottom. The material cylinder 801 is used to store the hanging seat 900.

[0023] In the above scheme: 1. Corner protector components: 1.1 The corner protectors 1 and 2 fit together at the four corners of the wood-plastic composite board stack to form rigid protection, avoiding collisions, wear and chipping of the four corners during stacking and transportation, and ensuring the appearance and structural integrity of the wood-plastic composite board.

[0024] 1.2 The assembly port provides end insertion space for wood-plastic waste parts, enabling a stable connection between the wood-plastic waste parts and the corner wrapping components; the sliding component drives the top block to misalign, which can make room for the assembly port, facilitating the insertion of waste parts. After resetting, the top block limits the waste parts through the interface to prevent the waste parts from falling off, and provides structural support for cross-packing.

[0025] 1.3 The diagonal distribution of the structural design and the cross-layout of the hanging base and wood-plastic waste parts are adapted to form a three-dimensional packaging structure with four corners and cross-shaped waste parts, which enhances the integrity and stability of the wood-plastic board stack and avoids loose stacking.

[0026] 2. Hanging bracket: 2.1 The wood-plastic waste parts are made from the waste materials cut from wood-plastic boards, realizing the resource utilization of waste materials and reducing packaging costs; the cross-distributed waste parts pass through the hanging base and corner components, firmly connecting the wood-plastic board stack, corner components, and hanging base into a whole, enhancing the stability of stacking and packaging, and preventing the boards from falling apart during transportation.

[0027] 2.2 The height difference design between placement port one and placement port two meets the space avoidance requirements when two wood-plastic waste parts are placed crosswise, ensuring that the crosswise layout is compact and does not interfere with each other, and further improving the overall integrity of the packaging structure; the two ends of the waste parts are inserted into the assembly ports of the corner wrapping components to form multi-point fixation and prevent the waste parts from shifting.

[0028] 2.3 The lifting ports on both sides of the lifting base provide convenient docking points for lifting equipment. During lifting, force is applied through the lifting ports, and the entire stack of wood-plastic composite boards can be lifted synchronously through the connection structure between the lifting base and the scrap parts. This avoids damage to the boards caused by direct lifting and improves the safety and convenience of transportation. 3. Operating Unit: 3.1 The adjustment component can flexibly adjust the position and angle of the operating component to adapt to different operational needs such as wood-plastic board extraction, waste clamping, and top block pushing; the flip-out operating component can realize quick switching of operating posture, avoid structural interference between different processes, and improve operational flexibility.

[0029] 3.2 The support frame provides stable installation and movement support for each operating component, ensuring precise and stable operation. The operating unit coordinates the extraction of wood-plastic composite boards from the conveyor, the extraction of waste materials from the collection unit, the stacking of the stacking platform, the auxiliary packaging and hoisting transfer of the corner components, realizing the automated connection of each process and reducing manual intervention.

[0030] 3.3 The layout design, which is mounted above the stacking platform, allows the operating components to cover the working areas of the stacking platform, conveyor, and collection unit, enabling multi-station operations to be completed without the need for moving equipment, thereby improving work efficiency.

[0031] 4. Collection Unit: 4.1 The diverted wood-plastic waste parts can be neatly stacked to avoid messy stacking of waste materials, ensure the integrity of waste parts, and provide qualified waste raw materials for subsequent reuse.

[0032] 4.2 The layout design extending into the operation unit allows the extraction components of the operation unit to directly extract waste parts from the collection unit without additional transportation, shortening the waste extraction path and improving the efficiency of packaging operations.

[0033] 4.3 It can store wood-plastic waste parts in batches to meet the waste needs of stacking and packaging multiple batches of wood-plastic boards, avoid frequent replenishment of waste materials, and ensure the continuity of packaging operations.

[0034] 5. Feeding unit: 5.1 The material cylinder can store hangers in batches, eliminating the need for frequent manual placement and enabling automated replenishment of hangers, reducing manual intervention and improving packaging efficiency; the feeding component can precisely control the feeding of individual hangers, preventing hangers from jamming or falling continuously, and ensuring orderly replenishment.

[0035] 5.2 Adjustment component two can drive the material cylinder to move laterally and lift, so that the material cylinder is accurately moved above the wood-plastic board stack, and the discharge port is in contact with the top surface of the stack, ensuring that the lifting seat is placed stably and accurately on the top of the wood-plastic board stack, providing a precise benchmark for the subsequent cross assembly of wood-plastic waste parts.

[0036] 5.3 It works in synergy with the operating unit and corner assembly, allowing for the assembly and packaging of scrap parts immediately after the hanging seat is placed, without the need for additional process adjustments, thus ensuring a smooth packaging process.

[0037] In this embodiment, the collecting unit 200 includes a base 201, an active guide rail 202, and a telescopic cylinder 203. The base 201 is provided on both sides of the conveyor 300. The active guide rail 202 is fixedly installed on the top of the base 201. A linearly movable placement plate 204 is slidably mounted on the active guide rail 202. Support plates 205 are fixedly installed on all four sides of the top of the placement plate 204. The telescopic cylinder 203 is fixedly installed on the outer side of the support plate 205. The output end of the telescopic cylinder 203 passes through the support plate 205 and is connected to a constraint plate 206.

[0038] The active guide rail can drive the placement plate to move linearly, making it easy to accurately transfer the collected waste parts to the operating unit's working range; The telescopic cylinder can push the constraint plate to flexibly adjust the spacing, adapt to the stacking of wood-plastic waste parts of different sizes, and prevent the waste parts from being stacked crookedly or scattered. The constraint plates on all four sides form a regular stacking space, ensuring that the waste parts are stacked neatly, facilitating the rapid extraction of waste parts by subsequent operation units, and ensuring a smooth connection between waste collection and reuse.

[0039] In this embodiment, diversion components 500 are assembled on both sides of the top of the conveyor 300. The diversion components 500 include diversion tongues 501 and movable seats 502. Movable seats 502 are fixedly installed on both sides of the top of the conveyor 300. An extended mounting arm 503 is rotatably installed inside the movable seat 502. An mounting sleeve 504 is fixedly installed at the end of the mounting arm 503. A through transverse rod 505 is fitted inside the mounting sleeve 504. A positioning knob 506 is threadedly rotated on the top of the mounting sleeve 504. The positioning knob 506 is used to position the transverse rod 505. A diversion tongue 501 is fixedly installed at one end of the transverse rod 505. The diversion tongue 501 is used to divert the wood-plastic waste parts 910 conveyed by the conveyor 300.

[0040] The movable seat allows for adjustment of the mounting arm's tilt angle, while the mounting sleeve and positioning knob can fix the position of the horizontal bar, thereby adjusting the spacing and position of the diverting tongues to accommodate wood-plastic composite boards of different cutting sizes. The diverting tongue can be precisely inserted between the wood-plastic composite board and the waste material, guiding the waste material to both sides of the conveyor while leaving the wood-plastic composite board in the middle, thus achieving automatic diversion of the two without the need for manual sorting. This not only improves sorting efficiency but also avoids damage to the wood-plastic composite board caused by human contact.

The suction cup 431 is fixedly connected to the bottom of the rotating cylinder 432. The rotating cylinder 432 is used to drive the suction cup 431 to rotate.

[0042] The second active lead screw can drive the lifting frame to move linearly, and the first active gear meshes with the rack to drive the lifting plate to rise and fall, so as to realize the precise movement of the extraction component to the extraction position; The rotary cylinder can drive the suction cup to rotate, and the suction cup can stably adsorb wood-plastic composite board or waste materials, adapting to the extraction posture requirements of different materials. The active guide rail 2 can drive the base plate to move longitudinally, further expanding the extraction operation range, enabling the extraction components to accurately move the wood-plastic composite board to the stacking platform and the waste to the collection unit, improving the accuracy and flexibility of extraction and transfer.

[0043] In this embodiment, the adjustment component 410 includes a rectangular frame 411, a flip plate 412, and a drive screw 413. The flip plate 412 is movably mounted on the base plate 427 via a flip ear 428. The rectangular frame 411 is fixedly mounted at the end of the flip plate 412. Two sets of guide plates 41a are slidably mounted inside the rectangular frame 411. The drive screw 413, threaded through the guide plates 41a, rotates inside the rectangular frame 411. The drive screw 413 drives the guide plates 41a to move accordingly. The top of the guide plate 41a is fixedly installed with a connecting plate 414, and the end of the connecting plate 414 is fixedly installed with a flip ear 41b. The inside of the flip ear 41b is actively rotated and installed with a flip plate 415. The bottom of the flip plate 415 is actively rotated and installed with a right angle plate 417.

The output end of the telescopic cylinder 41c passes through the right angle plate 417 and is connected to a gripper 416. The gripping end of the gripper 416 is equipped with a clamping plate 418.

[0044] The active lead screw can drive the guide plate to move relative to each other, and adjust the gap between the grippers; The flip ear one and flip plate two are equipped with motors for driving, which can be used to adjust the angle of the gripper. The right angle plate and telescopic cylinder two can push the gripper to move precisely. The clamping plates of the grippers can be inserted into the interface of the corner assembly, pushing the top block to offset and make room for the assembly port, which facilitates the assembly of scrap parts; after the assembly is completed, the clamping plates are removed without affecting the subsequent reset of the top block, ensuring the precise connection between scrap assembly and packaging. At the same time, the clamping plates can stably hold the scrap, preventing the scrap from shifting during the transfer process.

[0045] In this embodiment, the pushing assembly 600 includes a carrier plate 601, a third active screw 602, and a third telescopic cylinder 603. Two sets of carrier plates 601 are slidably mounted on both sides of the stacking platform 100. A second support plate 604 is fixedly installed on the top of the carrier plate 601.

The third active screw 602 is rotatably mounted on both sides of the stacking platform 100. The third active screw 602 is threaded through the carrier plate 601 and is used to drive the third active screw 602 to move in opposite directions.

[0046] The active lead screw can drive the carrier plate to move in opposite directions, and adjust the spacing of the two corner components to adapt to different sizes of wood-plastic composite board stacks; The telescopic cylinder can drive the triangular carrier to move smoothly. The triangular carrier can stably support the corner-wrapping components, ensuring that the corner-wrapping components are accurately fitted into the four corners of the wood-plastic board stack, avoiding corner offset, and ensuring the stability and accuracy of the corner-wrapping operation.

[0047] In this embodiment, a guide groove 725 is provided on the top of the triangular corner protector 721. The guide groove 725 is located behind the assembly port 724. Sliding grooves 727 are provided on the triangular corner protector 721 on both sides of the guide groove 725. The top of the triangular corner protector 731 is provided with a guide groove 735, which is located behind the assembly port 734. The triangular corner protector 731 on both sides of the guide groove 735 is provided with a sliding groove 737. Sliding component 1 710 includes a guide block 711, a slider 712, and a spring 713. The bottom of top block 1 722 and top block 2 732 are both fixedly mounted with guide blocks 711. Top block 1 722 and top block 2 732 extend into guide groove 1 725 and guide groove 2 735 through guide blocks 711. The side of guide block 711 is fixedly mounted with a spring 713. The bottom of top block 1 722 and top block 2 732 are both fixedly mounted with sliders 712. Triangular corner protectors 1 721 and 2 731 slide and limit each other with top block 1 722 and top block 2 732 through sliders 712. Sliding component 2 740 is composed of the same principle as sliding component 1 710.

[0048] The top block can slide smoothly through the cooperation of the guide block and guide groove, and the slider and slide groove; The spring is compressed when the clamping plate pushes the top block, making room for the insertion of scrap parts. After the clamping plate is removed, the spring component drives the top block to automatically reset, quickly limiting the end of the waste part in the assembly port to prevent the waste part from falling off and ensuring the firmness of the packaged structure. At the same time, the sliding structure makes the top block move smoothly, avoiding jamming and affecting work efficiency.

[0049] In this embodiment, the adjustment component 2 810 includes a guide frame 811 and a telescopic cylinder 4 812. The telescopic cylinder 4 812 is fixedly installed at the bottom of the support frame 401. The output end of the telescopic cylinder 4 812 is connected to the guide frame 811, and the top of the guide frame 811 is slidably connected to the support frame 401. A through-type n-shaped guide frame 813 is slidably installed at the bottom of the guide frame 811. The material cylinder 801 is fixedly installed on the outer side of the n-shaped guide frame 813. A telescopic cylinder 5 814 is fixedly installed at the bottom of the guide frame 811, and the output end of the telescopic cylinder 5 814 passes through the guide frame 811 and is installed and connected to the n-shaped guide frame 813. The telescopic cylinder 5 814 is used to drive the n-shaped guide frame 813 to rise and fall.

[0050] The telescopic cylinder can push the guide frame to slide laterally, driving the material cylinder to move precisely above the wood-plastic board stack; The telescopic cylinder drives the n-type guide frame to lift and lower, simultaneously lifting and lowering the material cylinder. This ensures that the material cylinder's discharge port is aligned with the top surface of the stack, guaranteeing that the lifting seat is stably placed on top of the stack. This provides a precise benchmark for subsequent assembly of scrap parts and ensures accurate connection between the feeding and packaging processes.

[0051] In this embodiment, the feeding assembly 820 includes a fixed frame 821, an upper distributing plate 822, and a lower distributing plate 823. The fixed frame 821 is fixedly installed at the bottom of both sides of the material cylinder 801. The lower distributing plate 823 is rotatably installed inside the fixed frame 821. The upper distributing plate 822 and the lower distributing plate 823 are respectively installed through the material cylinder 801 above and below the fixed frame 821. The inner sides of the upper distributing plate 822 and the lower distributing plate 823 are shovel-shaped. The inner sides of the upper distributing plate 822 and the lower distributing plate 823 are provided with toothed grooves 825. The toothed grooves 825 are used to mesh with the second drive gear 824. The lower distributing plate 823 is located at the feeding port of the material cylinder 801. The second drive gear 824 drives the upper distributing plate 822 and the lower distributing plate 823 to move in opposite directions through the toothed grooves 825.

[0052] The second drive gear drives the upper and lower distribution plates to move in opposite directions through the toothed track. When the lower distribution plate is retracted, the bottommost hanging seat falls smoothly to the top of the stack. The upper distribution plate is simultaneously inserted into the material cylinder to support the other hanging seats and prevent continuous falling. The shovel-shaped material distribution plate reduces friction with the lifting seat, prevents the lifting seat from jamming, enables precise individual material feeding from the lifting seat, and ensures the orderly and stable supply of materials to the lifting seat.

[0053] In this embodiment, a placement tray 101 is placed on one side of the stacking platform 100, and the placement tray 101 is used to place the packaged wood-plastic composite board; a slitting machine 301 is fixedly installed on the top of the conveyor 300, and the slitting machine 301 is used to slit the wood-plastic composite board on the conveyor 300. The wood-plastic composite waste part 910 is generated by slitting the wood-plastic composite board on both sides by the slitting machine 301.

[0054] The slitting machine can directly slit wood-plastic composite boards on a conveyor, and the resulting wood-plastic waste parts can be directly used for subsequent packaging, realizing the resource utilization of waste materials and reducing costs. The placement tray can specifically support the stacks of packaged wood-plastic composite boards, preventing them from scattering during transportation. It also provides a stable placement platform for the wood-plastic composite boards, facilitating subsequent warehousing and ensuring the safe transportation of packaged wood-plastic composite boards.

[0055] Working principle and operation process of this invention: S1, Material Distribution During the process, the wood-plastic composite board awaiting processing is guided by the conveyor 300 and then passed through the slitting machine 301 to obtain the required slitting operation. The purpose is to remove the waste material on both sides of the wood-plastic composite board. The slitting waste material is the wood-plastic waste part 910. During slitting, the operator flips down the mounting arm 503 and adjusts the distance between the horizontal bars 505. After completion, it can be positioned by the positioning knob 506 on the mounting sleeve 504. The purpose is to ensure that the front end of the diversion tongue 501 can be inserted between the slitting wood-plastic composite board and the waste material to divert and guide the two. In this way, the slitting waste material will be moved to both sides of the conveyor line of the conveyor 300 under the guidance of the diversion tongue 501, while the wood-plastic composite board is still located in the middle of the conveyor line of the conveyor 300. S2, Extraction and Stacking At this point, the slit wood-plastic composite board and waste strips can be extracted separately; Wood-plastic composite board extraction: The operating component 420 moves linearly to the top of the conveyor 300 via the second active screw 426, ensuring that the extraction component 430 is located in the middle of the wood-plastic composite board. Then, the first active gear 424 is activated and meshes with the rack 425 to transmit power, causing the guide seat 423 to descend synchronously with the hanging plate 422, causing the suction cup 431 to contact and adsorb the top surface of the wood-plastic composite board, thus completing the extraction of the wood-plastic composite board. Waste strip extraction: After the wood-plastic board is extracted, the motor on the flipping ear 41b is started to drive the shaft end of the flipping plate 415 to flip down. At that time, the components at its end will enter the working state. At this time, the gripper 416 drives the bottom clamping plate 418 to open. The position of the front gripper 416 is adjusted by starting the telescopic cylinder 41c, so that the clamping plate 418 can extend smoothly to both sides of the waste strip. Then, the gripper 416 drives the clamping plate 418 to complete the clamping and extraction of the waste. Once both have been extracted, the material can be lifted to remove the wood-plastic composite board and waste strip from the conveyor 300. Then, the active screw 413 is activated to drive the guide plate 41a, causing the two to expand in opposite directions. The purpose is to move the clamped waste strip above the collection unit 200. At this time, the collection unit 200 has been adjusted to conform to the placement shape and space of the waste strips; the adjustment method is as follows: the telescopic cylinder 203 is activated, and the output end of the telescopic cylinder 203 pushes the constraint plate 206, causing the spacing between the constraint plates 206 to be adjusted in real time. In this way, the spacing of the constraint plates 206 on the four sides of the top of the placement plate 204 is adjusted simultaneously, so that the spacing between the constraint plates 206 is adjusted to conform to the placement and stacking space of the waste strips, forming a waste strip stack. After completion, the adjustment component 410 is flipped up and reset. Then the adsorbed wood-plastic composite board is lifted again, and driven by the active screw 426, the extracted wood-plastic composite board is moved to the top of the stacking table 100 and lowered, so that the cut wood-plastic composite boards are stacked on the stacking table 100 in sequence. S3, Packed wood-plastic composite board stack Once the wood-plastic composite boards are stacked to the required size, the packaging process can begin. Personnel place the triangular corner protectors 1 721 and 2 731 required for packaging diagonally into the triangular carrier 605. After completion, the telescopic cylinder 3 603 can be activated to push the triangular carrier 605, causing the triangular corner protectors 1 721 and 2 731 in the triangular carrier 605 to be fitted into the four corners of the wood-plastic board stack. The telescopic cylinder 812 is activated to push the guide frame 811, causing the material cylinder 801 to move above the wood-plastic composite board stack. At this time, the operating component 420 is in the yielding state. Then, the telescopic cylinder 814 is activated to drive the n-shaped guide frame 813 to descend, and the material cylinder 801 descends synchronously. At this time, the discharge port of the material cylinder 801 has contacted the top surface of the stack. Then, the motor on the drive gear 824 is activated, causing the drive gear 824 to mesh and drive the upper distribution plate 822 and the lower distribution plate 823. The upper toothed channel 825 causes the two to move in opposite directions. At that time, the upper distribution plate 822 is inserted into the material cylinder 801, while the lower distribution plate 823 is retracted to the outside. The bottommost hanging seat 900 will fall to the top surface of the stack, and the hanging seat 900 inside the material cylinder 801 will be inserted into the inner upper distribution plate 822 for support and isolation. After placement, the entire feeding unit 800 assembly is reset. The operating component 420 and its bottom components are moved to the top of the stack. Activate the active guide rail 202 to linearly move the placement plate 204 with the stacked waste strips to both sides of the stacking platform 100, waiting for extraction. Extraction method: Activate the active guide rail 429 to move longitudinally, causing the suction cup 431 to move above the stacked waste strip pile, and then perform descent suction. Since the packaging operation requires the use of two waste strips, the waste strips in the two sets of collection units 200 are extracted one by one to ensure that the volume of the two sets of waste strip piles is consistent. Then, the extracted waste strip is moved above the hanging seat 900, and the rotating cylinder 432 is started to rotate, adjusting the waste strip above the second placement port 902, ready to be placed inside the second placement port 902; before placement, the motor on the second flip plate 415 is started to drive the right angle plate 417 to rotate, so that the front component is diagonally aligned with the triangular corner protectors 721 and 731 on the wood-plastic board stack. Then, the active screw 413 and the telescopic cylinder 41c are started to move the clamping plate 418 at the bottom of the gripper 416 to above the first interface 726 and the second interface 736, and after accurate positioning. The mechanism descends, causing the clamping plate 418 to insert into the diagonally opposite mating interfaces 726 and 736. Then, the telescopic cylinder 41c is activated again to push the respective mating top blocks 722 and 732. At that time, the top blocks 722 and 732 slide in their respective sliding grooves 727 and 737 via the slider 712, causing the top blocks 722 and 732 to drive the guide block 711 to slide and misalign. The purpose is to completely open the assembly port 724 at the top of the triangular corner protector 721 and the triangular corner protector 731, causing the spring 713 to enter the compressed state. This allows the extracted waste strips to be placed in placement port 2 902, and simultaneously both ends of the waste strips will be placed in the diagonally opposite assembly port 2 734. It is necessary to ensure that the waste strips are placed in placement port 2 902 first, and then placed in placement port 1 901. At the same time, both ends of the waste strips will be placed in the diagonally opposite assembly port 1 724. This is because the inner groove depth of placement port 2 902 is greater than that of placement port 1 901, which satisfies the height difference when the waste strips are placed crosswise. After placement, insert the clamping plates 418 into the first interface 726 and the second interface 736 to recycle. When the spring 713 loses its thrust, it can drive the top blocks 722 and 732 at their respective tops to reset. This will limit the ends of the waste strips inserted into the first assembly port 724 and the second assembly port 734, thus completing the packing operation of the wood-plastic board stack. Finally, the motor on the second flip ear 428 is started, driving the shaft on the first flip plate 412 to flip, causing the first flip plate 412 to enter the upward flipping state. The hanging plate 419 at the other end of the first flip plate 412 will then enter the downward flipping state. The whole structure is then lowered, causing the bottom of the hanging plate 419 to descend to both sides of the lifting port 903. Then, the motor on the second flip ear 428 is started again, driving the shaft on the first flip plate 412 to flip, causing the hanging plate 419 to flip upward. At the same time as it flips upward, the suspension structure at the end of the hanging plate 419 will be hooked into the lifting port 903. Then, the lifting seat 900 is lifted as a whole. The lifting seat 900, through the waste strip and the triangular corner protector 721 and the triangular corner protector 731, simultaneously lifts the stack of packaged wood-plastic composite boards, moves them above the placement tray 101 and places them there, thus stacking the packaged wood-plastic composite boards for subsequent warehousing.
