Description

Technical Field

[0001] This invention belongs to the field of wooden board stacking technology: specifically, it relates to a wooden board stacking machine. Background Technology

[0002] With the development of the modern machinery industry, the level of mechanization and automation of packaging, transportation, and palletizing of wood products has also greatly improved in recent years. In particular, due to the large-scale production, packaging, and transportation of wood products, it is necessary to develop corresponding storage, transportation, and palletizing mechanization facilities. Palletizing machinery is one of the key equipment for realizing the modernization of storage, transportation, and packaging of wood products. It can greatly reduce labor and labor intensity. Wood palletizing machines automatically stack wood products delivered by conveyors.

[0003] Existing technologies also offer some solutions: For example, a patent with publication number CN118047230A discloses a wooden board stacking and lifting machine, which includes a base plate, a stacking box fixedly connected to the base plate, a vacuum suction plate device fixedly connected to the upper end of the stacking box, four stacking devices symmetrically arranged inside the stacking box, and each stacking device including a stacking support shell, a support sleeve slidably connected inside the stacking support shell, and a compression spring fixedly connected to the left side of the support sleeve; the cooperation of the front limit mechanism and the limit support column can adjust the distance between the two front stacking devices according to the wooden board, so that the wooden board moves down along the space between the stacking devices. When the wooden board touches the trigger wedge, the support block moves down a corresponding distance according to the thickness of the wooden board, which is suitable for stacking wooden boards of different thicknesses.

[0004] When existing palletizing machines stack long wooden boards, the center of gravity of the long wooden boards is relatively far away. As the long wooden boards are stacked layer by layer, the center of gravity of each board is located at its geometric center. As the stacking height increases, the center of gravity is further away from the bottom support surface. Under handling or slight vibration, the stacking structure is prone to tilting, and in severe cases, it may even cause the entire stack to collapse.

[0005] Therefore, the present invention provides a wooden board stacking machine. Summary of the Invention

One end of the connecting rope 1 is fixedly connected to the outer wall of the collar 1, and the end of the connecting rope 1 away from the collar 1 is fixedly connected to the outer wall of the collar 2.

[0010] Preferably, the upper surface of the workbench is symmetrically provided with sliding grooves, and the bottom of the palletizing table is symmetrically fixedly connected with pulleys. The pulleys and the sliding grooves are slidably connected and adapted to each other. The outer side of the palletizing table is provided with a locking component, which is used to fix the position of the palletizing table.

[0011] Preferably, the positioning assembly includes two hinges, which are fixedly installed on both sides of the palletizing platform. The shaft of each hinge is hinged with a hinge rod, and an angle spring is fixedly connected to the back side of each hinge rod. The side of the angle spring away from the hinge rod is fixedly connected to the side of the palletizing platform, and a fixing block is provided on one side of the hinge rod.

[0012] Preferably, the inner wall of the hinge is fixedly connected to a limit rod, the outer wall of the limit rod is in contact with the outer wall of the hinge rod, and the bottom of the fixing block is provided with a pull-out component that drives the fixing block to move.

[0013] Preferably, the pull-out assembly includes two mounting bases, each with a movable block slidably connected to its inner wall. The movable block is fixedly connected to the bottom of a fixed block. A return spring is fixedly connected to one end of the movable block, and the other end of the return spring is fixedly connected to the inner wall of the mounting base. The fixed block is made of iron and has an electromagnet on one side. The electromagnet is fixedly installed on the top of the worktable. The elastic coefficient of the return spring is much greater than that of the angle spring.

[0014] Preferably, a movable pulley is fixedly installed on the top of the workbench, a connecting rope two is fixedly connected to one side of the stacking platform, a counterweight is fixedly connected to one end of the movable pulley, and the movable pulley and the connecting rope two are slidably connected.

[0015] Preferably, the fixing assembly includes multiple hinge seats, each of which is fixedly installed on the inner wall of the clamping table. Each of the multiple hinge seats has a support member hinged to its shaft. The number of the multiple support members corresponds one-to-one with the number of wooden boards. Each of the multiple hinge seats has a transmission ring fixedly connected to its top shaft. A transmission belt is fixedly connected between the outer walls of the multiple transmission rings.

[0019] 2. The wooden board stacking machine of the present invention transforms the longitudinal merging of multiple wooden boards into a transverse merging, with the boards perpendicular to the first layer of wooden boards. When the second layer of wooden boards descends above the first layer, the positioning clamping is released, completing the second stacking process. After the two clamping platforms descend and reset, the second servo motor drives the second servo motor to rotate in the opposite direction and reset. Then, the third layer of stacked wooden boards is placed, and the stacking process of the third layer of wooden boards is the same as that of the first layer. This process is repeated, and the vertically alternating stacked wooden boards form a mutually supporting structure, which enhances the overall stability and reduces the risk of wooden boards collapsing.

[0020] 3. The wooden board stacking machine of the present invention, through the positioning component, when the inner slider moves upward to the highest point, it will drive the stacking platform to move directly below the two clamping platforms through the connecting rope. When the inner slider descends, the position of the entire stacking platform will not change, and the connecting rope will remain slack between the two sides during the descent. This ensures that the wooden boards between the two clamping platforms can accurately fall on top of the previous layer of stacked wooden boards above the stacking platform, thereby achieving a precise stacking effect.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figures 1 to 10As shown, the present invention provides a technical solution: a wooden board stacking machine, including a workbench 1, a stacking platform 2 above the workbench 1, two clamping platforms 3 symmetrically arranged on one side of the stacking platform 2, a connecting frame 13 fixedly connected between the outer walls of the two clamping platforms 3, a crossbeam 14 on the top of the connecting frame 13, a servo motor 33 fixedly connected to the top of the crossbeam 14, the output shaft of the servo motor 33 fixedly connected to the top of the connecting frame 13, lifting components for driving the clamping platforms 3 to rise and fall on both sides of the clamping platforms 3, a fixing component for positioning and clamping the wooden boards between the two clamping platforms 3, and a pull rope component for driving the stacking platform 2 to move between the clamping platforms 3 and the stacking platform 2.

[0035] During operation: The palletizing platform 2 is used to stack multiple long wooden boards together. In the preparation stage, the multiple long wooden boards to be stacked are placed longitudinally between two clamping platforms 3. Through the set fixing components, the multiple long wooden boards can be automatically positioned. After positioning, the multiple long wooden boards are close to each other and stably clamped and fixed between the two clamping platforms 3. After the wooden boards are placed, the lifting component is activated. The lifting component first drives the two clamping platforms 3 and the multiple wooden boards positioned and clamped between the two clamping platforms 3 to move upward. During the upward movement, the palletizing platform 2 can be raised by the pull rope component. The palletizing platform 2 moves laterally across the upper surface of the workbench 1. The higher the two clamping platforms 3 rise, the greater the lateral movement of the palletizing platform 2. When the two clamping platforms 3 reach their highest point, the palletizing platform 2 is positioned directly below them. At this point, the lifting assembly lowers the two clamping platforms 3 and the wooden planks, keeping the palletizing platform 2 stationary directly below the two clamping platforms 3. Once the wooden planks are directly above the palletizing platform 2, the fixing assembly releases its clamping grip on the planks, and several long wooden planks automatically fall onto the palletizing platform 2. After the first layer is stacked, the palletizing platform 2 and the first layer of wooden planks can be reversed. Move the device back to one side of the clamping platform 3. When stacking the second layer of wooden boards, follow the same steps as above. When the two clamping platforms 3 and the clamped wooden boards rise to their highest positions, start the servo motor 33. Its output shaft will drive the connecting frame 13 to rotate 90 degrees. The connecting frame 13 will drive the two clamping platforms 3 to rotate 90 degrees. The two clamping platforms 3 will drive multiple wooden boards to descend and rotate. The multiple wooden boards will change from merging together longitudinally to merging together laterally, forming a perpendicular relationship with the first layer of wooden boards. When the second layer of wooden boards descends to above the first layer of wooden boards, release the positioning clamping, completing the second stacking process. After the clamping platform 3 descends and resets, servo motor 2 drives two servo motors 2 to rotate in opposite directions and reset. Then, the third layer of stacked wooden boards is placed. The stacking process of the third layer of wooden boards is the same as that of the first layer, and so on. The vertically alternating stacked wooden boards form a mutually supporting structure, which enhances the overall stability and reduces the risk of the boards collapsing. Through the coordinated work of the lifting component and the rope component, after each wooden board rises, the palletizing platform 2 is positioned directly below the two clamping platforms 3, ensuring stacking accuracy. Together, they promote the efficient and stable operation of the palletizing process and improve the stacking quality and efficiency of the wooden boards.

[0036] like Figures 2 to 3 As shown, the lifting assembly includes two fixed seats 15, both of which are fixedly installed on the top of the workbench 1. The inner walls of the two fixed seats 15 are slidably connected to inner sliders 17. The bottom of the crossbeam frame 14 is fixedly connected to the top of the two inner sliders 17. The top of the fixed seats 15 is fixedly installed with hydraulic cylinders 16, and the output end of the hydraulic cylinders 16 is fixedly connected to the top of the inner sliders 17.

[0037] During operation: After the wooden board is placed between the two clamping platforms 3 and positioned and clamped by the fixing components, the hydraulic cylinder 16 is activated. Its output shaft will drive the inner slider 17 to rise. During the rise, the inner slider 17 will stably move along the inner wall of the fixed seat 15. During the rise, the inner slider 17 will drive the crossbeam frame 14 to rise. The crossbeam frame 14 will drive the two clamping platforms 3 to rise through the connecting frame 13, thereby driving the wooden boards that have been positioned and clamped together to rise. Similarly, the hydraulic cylinder 16 can also drive the inner slider 17 to descend along the inner wall of the fixed seat 15, thereby driving the wooden boards to descend.

[0038] like Figure 2 and Figure 7 As shown, the pull rope assembly includes two connecting ropes 19. The bottoms of the two inner sliders 17 are fixedly connected to the middle of both sides of the palletizing platform 2 with fixing rings 21. The fixing rings 21 connected to the bottom of the inner sliders 17 are fitted with collars 18. The fixing rings 21 connected to the side of the palletizing platform 2 are fitted with collars 20. One end of the connecting rope 19 is fixedly connected to the outer wall of the collar 18, and the end of the connecting rope 19 away from the collar 18 is fixedly connected to the outer wall of the collar 20.

[0039] During operation: In the initial state, the connecting rope 19 is kept taut. When the inner slider 17 rises, it applies an upward traction force to one end of the connecting rope 19 through the fixed ring 21 and collar 18 connected to its bottom. After being pulled, the end of the connecting rope 19 is converted into a tension force, which acts on the fixed ring 21 connected to the side of the stacking platform 2 through the collar 20. This causes the stacking platform 2 to move laterally along the surface of the workbench 1. When the inner slider 17 rises to its maximum height, the stacking platform 2 is pulled directly below the two clamping platforms 3. The connecting rope 19 remains taut in a vertical state, ensuring that the stacking platform 2 is directly below the two clamping platforms 3 after each rise of the wooden board, thus ensuring stacking accuracy and promoting the efficient and stable operation of the stacking process.

[0040] like Figures 6 to 7 As shown, the upper surface of the workbench 1 is symmetrically provided with sliding grooves 23, and the bottom of the palletizing platform 2 is symmetrically fixedly connected with pulleys 22. The pulleys 22 and the sliding grooves 23 are slidably connected and adapted to each other. The outer side of the palletizing platform 2 is provided with a locking component, which is used to fix the position of the palletizing platform 2.

[0041] During operation: When the inner slider 17 moves upward to the highest point, it will drive the palletizing platform 2 to move directly below the two clamping platforms 3 through the connecting rope 19. At this time, under the action of the positioning component, the palletizing platform 2 remains stationary in this position. When the inner slider 17 drives the clamping platform 3 and the wooden board to descend, the palletizing platform 2 is always located directly below the clamping platform 3 and the wooden board until the wooden board is placed directly above the palletizing platform 2 or above the wooden board of the previous layer.

[0042] like Figures 8 to 9 As shown, the positioning assembly includes two hinges 24, which are fixedly installed on both sides of the palletizing platform 2. The shafts of the hinges 24 are all hinged to hinge rods 25. Angle springs 27 are fixedly connected to the back side of the hinge rods 25. The side of the angle springs 27 away from the hinge rods 25 is fixedly connected to the side of the palletizing platform 2. A fixing block 28 is provided on one side of the hinge rods 25.

[0043] During operation: When the inner slider 17 rises, causing the palletizing platform 2 to move laterally along the upper surface of the workbench 1, it will drive the hinge rod 25 to gradually approach the fixed block 28. When the outer wall of the hinge rod 25 slowly contacts the side of the fixed block 28, the hinge rod 25 will rotate hingedly around the axis of the hinge member 24. When the hinge rod 25 rotates hingedly, it will compress the angle spring 27 and cause it to deform. At this time, the angle between the hinge rod 25 and the side of the palletizing platform 2 becomes smaller, allowing the hinge rod 25 to pass smoothly through one side of the fixed block 28. When the palletizing platform 2 moves directly under the wooden board... At this time, the end of the hinge rod 25 away from the hinge member 24 moves to one side of the fixed block 28. At this time, the angle spring 27 restores its deformation so that the end of the hinge rod 25 away from the hinge member 24 is just in contact with one side of the fixed block 28. Under the restriction of the fixed block 28, the position of the entire stacking platform 2 will not change when the inner slider 17 descends. The connecting rope 19 remains slack between the two sides during the descent. This ensures that the wooden board between the two clamping platforms 3 can fall accurately onto the previous layer of stacked wooden boards above the stacking platform 2, thus achieving the effect of precise stacking.

[0044] like Figures 8 to 9 As shown, the inner wall of the hinge 24 is fixedly connected to a limit rod 26, the outer wall of the limit rod 26 is in contact with the outer wall of the hinge rod 25, and the bottom of the fixing block 28 is provided with a pull-opening component that drives the fixing block 28 to move.

[0045] During operation: When the end of the hinge rod 25 away from the hinge member 24 is just in contact with one side of the fixed block 28, under the restriction of the limit rod 26, when the stacking platform 2 is subjected to a backward pulling force, the hinge rod 25 and the hinge member 24 will not rotate, and the angle spring 27 will not be stretched to make the included angle between the hinge rod 25 and the side of the stacking platform 2 larger. Moreover, through the set pull-out component, the fixed block 28 can move and no longer be in contact with one end of the hinge rod 25, so that after the wooden boards are stacked, the entire stacking platform 2 can move in the opposite direction and reset to one side of the clamping platform 3.

[0046] like Figures 9 to 10As shown, the pull-out assembly includes two mounting bases 30. The inner walls of the mounting bases 30 are slidably connected to movable blocks 29. The movable blocks 29 are fixedly connected to the bottom of the fixed blocks 28. One end of the movable blocks 29 is fixedly connected to a return spring 31, and the other end of the return spring 31 is fixedly connected to the inner side wall of the mounting base 30. The fixed block 28 is made of iron and has an electromagnet 32 ​​on one side. The electromagnet 32 ​​is fixedly installed on the top of the workbench 1. The elastic coefficient of the return spring 31 is much greater than that of the angle spring 27.

[0047] During operation: After the wooden boards are stacked, current is applied to the electromagnet 32. The electromagnet 32 ​​can attract the ferrous fixing block 28. After being attracted by the electromagnet 32, the fixing block 28 will slide along the inner wall of the mounting base 30 through the movable block 29 and squeeze the return spring 31. This makes the fixing block 28 no longer stick to one end of the hinge rod 25, which facilitates the subsequent reset of the entire stacking platform 2. Since the elastic coefficient of the return spring 31 is much greater than that of the angle spring 27, when the hinge rod 25 moves along the side of the fixing block 28, it will only squeeze the angle spring 27 to deform it. The hinge rod 25 will not push the fixing block 28 to squeeze the return spring 31 to move. After the stacking platform 2 is reset, the electromagnet 32 ​​is de-energized. At this time, under the action of the return spring 31, the fixing block 28 moves in the opposite direction to reset, preparing for the next operation.

[0048] like Figure 6 As shown, a movable pulley 34 is fixedly installed on the top of the workbench 1, and a connecting rope 35 is fixedly connected to one side of the stacking platform 2. A counterweight 36 is fixedly connected to one end of the movable pulley 34, and the movable pulley 34 and the connecting rope 35 are slidably connected.

[0049] During operation: When the inner slider 17 rises and the palletizing platform 2 moves laterally, it will pull the counterweight 36 to move upward. When the palletizing platform 2 moves directly below the two clamping platforms 3 and the wooden board, although the position of the palletizing platform 2 will not change under the action of the locking component, the palletizing platform 2 will always be pulled by the counterweight 36 on one side. When the component is pulled open so that the fixing block 28 is no longer in contact with one end of the hinge rod 25, the palletizing platform 2 can automatically move back to the initial position under the action of the counterweight 36, and the connecting rope 19 will be kept taut again. The entire device returns to the initial position, which facilitates the stacking of the next layer of wooden boards.

[0050] like Figures 3 to 4As shown, the fixing assembly includes multiple hinge seats 4, which are all fixedly installed on the inner wall of the clamping platform 3. Each of the multiple hinge seats 4 has a support member 5 hinged to its shaft. The number of the multiple support members 5 corresponds one-to-one with the number of wooden boards. Each of the multiple hinge seats 4 has a transmission ring 10 fixedly connected to its top shaft. A transmission belt 11 is fixedly connected between the outer walls of the multiple transmission rings 10. A servo motor 12 is fixedly installed on the top of the clamping platform 3. The output shaft of the servo motor 12 is fixedly connected to the top of one of the transmission rings 10.

[0051] During operation: Multiple support members 5 provide bottom support for multiple wooden boards. When multiple wooden boards are about to fall directly above the palletizing platform 2 or above the upper layer of wooden boards, the servo motor 12 is activated. It will drive one of the transmission rings 10 to rotate through the output shaft. The transmission ring 10 will drive multiple transmission rings 10 to rotate through the transmission belt 11, so that the support members 5 hinge around the shaft of the hinge seat 4 as the center point. This causes multiple support members 5 to rotate into the interior of the clamping platform 3, no longer supporting the bottom of the wooden boards, so that multiple wooden boards fall directly above the palletizing platform 2 or above the upper layer of wooden boards.

[0052] like Figures 4 to 5 As shown, an electric slide rail 6 is fixedly connected to one side of the connecting frame 13. Electric sliders 7 are symmetrically slidably connected to the inner wall of the electric slide rail 6. Two push blocks 8 are provided at the bottom of each of the two electric sliders 7. The top of one of the push blocks 8 is fixedly connected to the bottom of the electric slider 7. A connecting plate 9 is fixedly connected between the two push blocks 8 under the same electric slider 7.

[0053] During operation: When multiple wooden boards are placed between two clamping platforms 3, the two electric sliders 7 are controlled to move closer to each other along the inner wall of the electric slide rail 6, so that the two sets of push blocks 8 move closer to each other at the same time and squeeze the multiple wooden boards, so that the multiple wooden boards are tightly pressed together, and each wooden board is located directly above each support 5 in a one-to-one correspondence. The position between the multiple wooden boards in each layer is checked, and when multiple wooden boards fall on top of the wooden boards of the previous layer, there will be no positional deviation between them, so that each side of the wooden boards is in a flat state after stacking, improving the stability of stacking.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
