Description

Technical Field

[0001] This invention relates to the field of engineered wood stacking technology, specifically to an engineered wood stacking device. Background Technology

[0002] Engineered wood products (AWD) are composite materials made from wood or other non-wood plant fibers, which are mechanically processed into various unit materials, then bonded with adhesives and hot-pressed. The core technology lies in replacing the structural integrity of natural wood through physical recombination and chemical bonding. In the production of engineered wood products, in order to eliminate the risk of geometric deformation caused by thermal stress, control the continuous curing process of the adhesive, and prevent the interference of environmental humidity fluctuations on the moisture content of the board, a systematic control is achieved through stacking. The stacking operation, through standardized layering structure and static conditions, provides a uniform heat dissipation path for the board to slowly release internal stress, maintain a stable microenvironment to promote the full cross-linking and curing of the adhesive, and at the same time, uses interlayer physical isolation to buffer the penetration of external moisture, thereby ensuring that the board maintains dimensional accuracy and mechanical property stability during storage.

[0003] To improve ventilation, heat dissipation, stress uniformity, and moisture buffering after board stacking, spacer strips are typically placed between the boards during stacking to ensure the stability of the stacking structure and the quality of the boards. In the board stacking process, manual operation offers flexibility, so the placement of these spacer strips is primarily done manually. However, in actual operation, factors such as varying operator skill levels, continuous fatigue, and board displacement during stacking can easily lead to positioning deviations, causing vertical misalignment of the spacer strips between adjacent stacking layers. This misalignment interrupts the stress transmission path within the stack, creating localized stress concentration, which can lead to board flatness deviations or core layer cracks. Furthermore, misaligned strips alter the preset airflow distribution pattern, reducing ventilation and heat dissipation efficiency and causing abnormal moisture content gradients, ultimately inducing the risk of overall instability in the stacking structure. Therefore, we propose a board stacking device. Summary of the Invention

[0004] One of the technical problems this application aims to solve is that factors such as the varying skill levels of operators, continuous fatigue, and board displacement during the board stacking process can easily cause positioning deviations, resulting in vertical misalignment of the wooden strips between adjacent stacking layers. Such misalignment will interrupt the stress transmission path inside the stack, forming a local stress concentration phenomenon, which in turn will cause board flatness deviations or core layer crack defects.

[0005] To address the aforementioned technical problems, this application provides a board stacking device, including a conveying device, a support, and a hydraulic lifting rod. A transfer plate is mounted on the hydraulic lifting rod, and L-shaped limiting plates are mounted on both sides of the transfer plate. A positioning frame is provided on the support, and multiple limiting guide rails are mounted on the positioning frame. A board stacking unit connected to the transfer plate and limiting plates is provided on the support. During the board stacking process, the transfer plate and limiting plates are driven to deflect to receive the board falling from the conveying device. Then, the hydraulic lifting rod drives the transfer plate to descend, and during unloading, the transfer plate is controlled to deflect to a horizontal position. Simultaneously, the limiting plates on both sides are controlled to move in the opposite direction to detach from the board. A wooden strip placement unit connected to the limiting guide rails is provided on the support. When the board falls, the limiting guide rails push the spaced wooden strips to a predetermined position below the board, and the wooden strips are kept in place during placement.

[0009] In some embodiments, the power component includes a power chamber mounted on a transfer plate, a piston plate slidably mounted inside the power chamber, an extension rod mounted on one side of the piston plate, one end of the extension rod passing through the power chamber, a drive rack mounted on the other end of the extension rod outside the power chamber, a drive gear meshing with the drive rack mounted on the rotating shaft, a return spring mounted inside the power chamber, a turntable mounted on the power shaft, a second pull rope mounted on the turntable, and the second pull rope passing through the power chamber and the return spring and connected to the piston plate.

[0010] In some embodiments, the wood strip placement unit includes a pusher disposed on a positioning frame, which drives the limiting guide rail to move; a lifting member is disposed on the positioning frame, which drives the limiting guide rail to rise; and a driving member is disposed on the positioning frame, which drives the lifting member to work.

[0011] In some embodiments, the pusher includes a support plate slidably disposed on a positioning frame, a vertical plate disposed on the support plate, a push screw rotatably disposed on the vertical plate, one end of the push screw being connected to a motor, a push plate disposed on the push screw, the push plate being a C-shaped plate, a through rod disposed on the push plate, the through rod being slidably connected to a limiting guide rail, a pressing rod slidably disposed on the push plate, and a pressing bolt disposed on the push plate for use with the pressing rod, the pressing bolt being threadedly connected to the push plate.

[0012] In some embodiments, the lifting component includes a lifting screw rotatably mounted on a positioning frame, the lifting screw passing through a bearing plate and threadedly connected to the bearing plate, the lifting screw being provided with a lifting pulley, and a lifting belt being sleeved on the lifting pulley.

[0013] In some embodiments, the driving component includes a limiting rail disposed on a positioning frame, a linkage gear disposed on the lifting screw, and the linkage gear being connected to the lifting screw via a one-way bearing. A driving plate is slidably disposed within the limiting rail, and a linkage rack is disposed on the driving plate that meshes with the linkage gear.

[0014] In some embodiments, the push plate is provided with scale markings.

[0015] This invention has at least the following beneficial effects:

[0016] 1. The coordinated deflection mechanism of the hydraulic lifting rod and the transfer plate enables precise reception and unloading of the artificial board during its descent, eliminating displacement errors caused by manual handling. Next, the wood strip placement unit applies dynamic constraints to the spaced wood strips using limiting guide rails, ensuring they maintain their predetermined positions under the impact of falling boards and stacking pressure, thus blocking offset paths caused by vibration or fatigue. Finally, the rigid guiding structure formed by the L-shaped limiting plate and the positioning frame solidifies the spatial relationship of the wood strips throughout the stacking process, ensuring strict alignment of adjacent layers of wood strips, thereby maintaining the continuity of the stress transmission path and avoiding localized stress concentration. Overall, this device replaces manual labor with mechanical linkage, effectively mitigating the impact of technical differences and operational fatigue on positioning accuracy, and significantly improving the structural stability of the stack and the yield of finished boards.

[0029] 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.

[0030] Example 1: Please refer to Figure 1-10This invention provides a technical solution: a board stacking device, including a conveying device 1, a support 2, and a hydraulic lifting rod 3. A transfer plate 4 is installed on the hydraulic lifting rod 3, and L-shaped limiting plates 5 are installed on both sides of the transfer plate 4. A positioning frame 6 is provided on the support 2, and multiple limiting guide rails 7 are installed on the positioning frame 6. A board stacking unit 8 connected to the transfer plate 4 and the limiting plates 5 is provided on the support 2 to drive the transfer plate 4 and the limiting plates 5 to deflect during the board stacking process to receive the board falling from the conveying device 1. Then, the hydraulic lifting rod 3 drives the transfer plate 4 to lower the board, and during the unloading process, the transfer plate 4 is controlled to deflect to a horizontal position, while the limiting plates 5 on both sides are controlled to move in the opposite direction to detach from the board. A wooden strip placement unit 12 connected to the limiting guide rails 7 is provided on the support 2 to drive the limiting guide rails 7 to push the spaced wooden strips to a predetermined position below the board when the board falls, and to keep the wooden strips in a limited position during the placement process.

[0031] The board stacking unit 8 includes a deflector 9 disposed on the transfer plate 4, which controls the deflection of the transfer plate 4. A limiting member 10 is disposed on the deflector 9, which limits the artificial board entering the transfer plate 4. A power member 11 is disposed on the limiting member 10, which provides power for the operation of the limiting member 10.

[0032] The deflecting component 9 includes a base 92 mounted on the hydraulic lifting rod 3, a deflecting shaft 93 rotatably mounted on the base 92, a connecting plate 91 mounted on the deflecting shaft 93 and connected to the transfer plate 4, a deflecting gear 94 mounted on the deflecting shaft 93, a power shaft 95 rotatably mounted on the base 92, a power gear 96 meshing with the deflecting gear 94 mounted on the power shaft 95, and one end of the power shaft 95 connected to a motor.

[0033] When stacking the plates, the hydraulic lifting rod 3 is first activated to drive the transfer plate 4 to rise. During the rise of the transfer plate 4, the motor drives the power shaft 95 to rotate. The rotation of the power shaft 95 drives the power gear 96 to rotate, which in turn drives the deflection gear 94 meshing with the power gear 96 to rotate. The rotation of the deflection gear 94 drives the deflection shaft 93 to rotate, which in turn drives the connecting plate 91 connected to the deflection shaft 93 to deflect. The deflection of the connecting plate 91 drives the transfer plate 4 to deflect, so that the transfer plate 4 is in an inclined state when it rises to the predetermined height.

[0034] The deflection control of the transfer plate 4 is achieved through a gear meshing transmission mechanism. Compared with the ordinary direct drive mode of the motor shaft, its advantage is that the gear system can amplify the output torque and refine the angle adjustment accuracy, ensuring that the transfer plate 4 can complete the high stability adjustment of the tilt angle synchronously during the lifting process, avoiding the deflection deviation caused by the inertial impact of the direct drive of the motor or the sudden change of load. At the same time, the transfer plate 4 in the tilted state can support the falling plate with the inclined surface, and guide the plate to slide naturally to the predetermined stacking position by using the gravity self-balancing effect. This reduces the positioning error caused by manual intervention and reduces the risk of impact damage between the plate and the transfer plate 4 through the inclined surface buffer.

[0035] The limiting component 10 includes through slots 101 formed at both ends of the transfer plate 4. A fixing plate 103 is disposed within the through slots 101. A bidirectional lead screw 104 is rotatably mounted on the fixing plate 103. Movable blocks 102 are slidably connected to the through slots 101 at both ends of the bidirectional lead screw 104, and the movable blocks 102 are connected to the limiting plate 5. A synchronous pulley 105 is disposed on the bidirectional lead screw 104, and a synchronous belt 106 is sleeved on the synchronous pulley 105. A spring box 108 is disposed on the fixing plate 103 and rotatably connected to the bidirectional lead screw 104. A spring spring 109 is disposed within the spring box 108, and one end of the spring spring 109 is connected to the bidirectional lead screw 104. The connection includes a winding wheel 107 on the bidirectional lead screw 104, a positioning plate 1010 on the transfer plate 4, a rotating shaft 1011 rotatably mounted on the positioning plate 1010, a winding wheel 1012 mounted on the rotating shaft 1011, and a pull rope 1013 mounted on the winding wheel 1012, the other end of which is connected to the winding wheel 107. Positioning shafts 1014 are rotatably mounted on both sides of the transfer plate 4, a centering rod 1015 is mounted on the positioning shafts 1014, a positioning gear 1016 is mounted on the positioning shafts 1014, and a positioning rack 1017 meshing with the positioning gear 1016 is mounted on the limiting plate 5.

[0036] When the rotating shaft 1011 rotates, it drives the winding wheel 1012 mounted on it to wind up the wire. The winding wheel 1012 drives the pull rope to retract, thereby driving the winding wheel 107 connected to the other end of the pull rope to rotate. The rotation of the winding wheel 107 drives the single bidirectional lead screw 104 to rotate. The rotation of the single bidirectional lead screw 104 drives the synchronous pulley 105 to rotate. The rotation of the synchronous pulley 105 drives the two bidirectional lead screws 104 to rotate synchronously through the synchronous belt 106. At this time, the spring 109 stores power. The rotation of the two bidirectional lead screws 104 drives the moving blocks 102 on both sides and the limiting plate 5 connected to the moving blocks 102 to move towards each other. During unloading... When the transfer plate 4 is reset, the spring 109 releases its elastic force, causing the bidirectional lead screw 104 to move in opposite directions, causing the limiting plate 5 to disengage from the artificial board. As the limiting plates 5 on both sides move, they drive the positioning rack 1017 to move. The movement of the positioning rack 1017 drives the positioning gear 1016 meshing with it to rotate. The rotation of the positioning gear 1016 causes the positioning shaft 1014 and the centering rod 1015 mounted on the positioning shaft 1014 to deflect, so that the artificial board on the transfer plate 4 is pushed to the middle position. The centering rod 1015 is elastic, which can prevent damage to the board during the pushing process.

[0037] The rigid coupling between the bidirectional lead screw 104 and the synchronous belt 106 via the synchronous pulley 105 ensures that the two limit plates 5 move in strict synchronization and opposite directions, eliminating asymmetric displacement errors caused by manual operation. The energy storage and release mechanism of the spring 109 drives the limit plate 5 to automatically detach from the plate during unloading, avoiding reset deviation caused by manual intervention. The meshing transmission between the positioning rack 1017 and the positioning gear 1016 converts the translation of the limit plate 5 into the precise deflection of the centering rod 1015, forcing the plate to be centered. At the same time, the elastic centering rod 1015 is designed to offset the rigid thrust through deformation buffering, preventing damage to the plate surface.

[0038] The power component 11 includes a power chamber 111 mounted on the transfer plate 4. A piston plate 112 is slidably mounted inside the power chamber 111. An extension rod 113 is mounted on one side of the piston plate 112. One end of the extension rod 113 passes through the power chamber 111, and a drive rack 114 is mounted on the other end of the extension rod 113 outside the power chamber 111. A drive gear 115 that meshes with the drive rack 114 is mounted on the rotating shaft 1011. A return spring 116 is mounted inside the power chamber 111. A turntable 118 is mounted on the power shaft 95. A second pull rope 117 is mounted on the turntable 118. The second pull rope 117 passes through the power chamber 111 and the return spring 116 and is connected to the piston plate 112.

[0039] When the turntable 118 rotates, it causes the pull rope 117 to wind up, which in turn causes the piston plate 112 connected to the pull rope 117 to move. The movement of the piston plate 112 causes the extension rod 113 to move, and the movement of the extension rod 113 causes the drive rack 114 to move, which in turn causes the drive gear 115 meshing with the drive rack 114 to rotate. The rotation of the drive gear 115 causes the rotating shaft 1011 to rotate.

[0040] Through a composite transmission mechanism combining rope winding and gear rack meshing, the rotational motion of turntable 118 is converted into the linear displacement of drive rack 114, which in turn drives rotating shaft 1011 to perform directional rotation. The preload of return spring 116 in power chamber 111 and the cooperation of piston plate 112 sliding structure ensure the reset accuracy and stroke consistency of drive rack 114 reciprocating motion, eliminating reset deviations in manual operation. The rigid meshing transmission between rotating shaft 1011 and drive gear 115 avoids the elastic deformation error of traditional chain transmission, ensuring strict synchronization between the deflection angle of centering rod 1015 and the displacement of limit plate 5. The overall pure mechanical linkage design reduces energy consumption and avoids the complexity of electrical control system, thereby improving stacking positioning accuracy and enhancing system reliability.

[0041] The wood strip placement unit 12 includes a pusher 13 disposed on the positioning frame 6, which drives the limiting guide rail 7 to move. The positioning frame 6 is provided with a lifting member 14, which drives the limiting guide rail 7 to rise. The positioning frame 6 is provided with a driving member 15, which drives the lifting member 14 to work.

[0042] The pusher 13 includes a support plate 131 slidably disposed on the positioning frame 6, a vertical plate 132 disposed on the support plate 131, a push screw 133 rotatably disposed on the vertical plate 132, one end of the push screw 133 being connected to a motor, a push plate 135 disposed on the push screw 133, the push plate 135 being a C-shaped plate, a through rod 136 disposed on the push plate 135, the through rod 136 being slidably connected to the limiting guide rail 7, a pressing rod 137 slidably disposed on the push plate 135, and a pressing bolt 138 disposed on the push plate 135 for use with the pressing rod 137, and the pressing bolt 138 being threadedly connected to the push plate 135.

[0043] Before placing the spacer strips, the staff can adjust the spacing between the spacer strips according to the characteristics of the board, such as humidity and temperature. When adjusting, first turn the pressing bolt 138 to release the pressing rod 137 from the limiting guide rail 7. After that, adjust the spacing between the limiting guide rails 7. After adjustment, turn the pressing bolt 138 again to push the pressing rod 137 to press and fix the pressing guide rails again. After that, place the spacer strips between the limiting guide rails 7. Then the motor works to drive the push screw 133 to rotate, which in turn drives the push plate 135 and the limiting guide rails 7 to move the spacer strips to the predetermined position under the board.

[0044] Through the coordinated action of the adjustable limit guide rail 7 and the mechanical pushing mechanism, while retaining the flexibility of manual adjustment of the spacing between the wooden strips to adapt to the temperature and humidity characteristics of the board, the rigid locking mechanism of the compression bolt 138 completely eliminates the risk of displacement of the wooden strips during the conveying process; the C-shaped push plate 135 driven by the push screw 133, combined with the guiding constraint of the through rod 136, ensures that the wooden strips move accurately along the predetermined trajectory to the target position below the board, avoiding vertical misalignment caused by differences in technology or fatigue during manual placement; overall, the mechanism maintains the absolute stability of the wooden strip positioning by combining semi-automatic control with the advantages of manual judgment, and fundamentally ensures the structural homogeneity and interlayer alignment accuracy of the stack.

[0045] The lifting component 14 includes a lifting screw 141 rotatably mounted on the positioning frame 6. The lifting screw 141 passes through the bearing plate 131 and is threadedly connected to the bearing plate 131. A lifting pulley 142 is arranged on the lifting screw 141, and a lifting belt 143 is sleeved on the lifting pulley 142.

[0046] The driving component 15 includes a limiting track 151 disposed on the positioning frame 6, a linkage gear 152 disposed on the lifting screw 141, and the linkage gear 152 is connected to the lifting screw 141 through a one-way bearing. A driving plate 153 is slidably disposed in the limiting track 151, and a linkage rack 154 that meshes with the linkage gear 152 is disposed on the driving plate 153.

[0047] After stacking one layer of boards, the drive plate 153 is manually moved to move the linkage rack 154, which in turn drives the linkage gear 152 to rotate. The rotation of the linkage gear 152 drives the lifting screw 141 to rotate, and through the lifting pulley 142 and the lifting belt 143, multiple lifting screws 141 rotate synchronously. The rotation of the lifting screw 141 drives the bearing plate 131, which is threaded to it, to rise, and the rising distance is the thickness of the board. At the same time, the linkage gear 152 and the lifting screw 141 are connected by a one-way bearing, which can prevent the linkage rack 154 from driving the lifting screw 141 to rotate when it resets.

[0048] The linkage rack 154 drives multiple lifting screws 141 to rotate synchronously, ensuring that the bearing plate 131 is raised horizontally and the displacement is strictly equal to the thickness of a single layer of plate. This eliminates the layer height deviation caused by manual measurement or mechanical vibration, and while maintaining the flexibility of manual operation, the pure mechanical structure ensures the stacking layer height accuracy and overall structural stability.

[0049] Example 2: Please refer to Figure 11 The present invention provides a technical solution: the push plate 135 is provided with a scale mark 16, which provides operators with an intuitive size reference. The spacing between the wood strips is directly quantified by the numerical scale, avoiding random errors caused by manual visual estimation, and ensuring that the spacing can be consistent for different batches or operators. Combined with the temperature and humidity characteristics of the board, the operator can quickly adjust the spacing between the wood strips to the preset value according to the scale, taking into account both manual flexibility and mechanical precision. At the same time, the operator does not need to repeatedly measure and verify, but can directly refer to the scale mark 16 to complete the spacing setting, which significantly shortens the adjustment time and improves the production line efficiency.
