[0002] With the development of the modern machinery industry, the level of mechanization and automation of the packaging, transportation and palletizing of wooden board products has also developed and improved greatly in recent years. In particular, due to the large-scale production, packaging and transportation of wooden boards, it is bound to require the development of corresponding mechanized storage and palletizing facilities. Palletizing machinery is one of the key equipment to realize the modernization of storage and packaging of wooden board products, which can greatly reduce labor and reduce labor intensity. The wooden board palletizer is a conveyor that automatically stacks and stacks wooden boards.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

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

[0035] During operation: the upper part of the stacking 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 the two clamping platforms 3. Through the set fixing components, the multiple long wooden boards can be automatically positioned. After the positioning, the multiple long wooden boards are close to each other and stably clamped and fixed between the two clamping platforms 3. After the placement of the wooden boards is completed, the lifting component is started. 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, and in the process of rising and moving, the stacking platform 2 can be made to move upward through the pull rope component. When the two clamping platforms 3 are raised to the highest point, the stacking platform 2 can be located just below the two clamping platforms 3. At this time, when the two clamping platforms 3 and the wooden planks are lowered by the lifting assembly, the stacking platform 2 can remain motionless just below the two clamping platforms 3. When the wooden planks are lowered to the top of the stacking platform 2, the fixing assembly cancels the positioning and clamping of the wooden planks, and several long wooden planks automatically fall into the top of the stacking platform 2. After the first layer of stacking is completed, the stacking platform 2 and the first layer of wooden planks can be reversed. The two clamping tables 3 move back to one side of the clamping table 3. When stacking the second layer of wooden boards, the steps are the same as the above steps. When the two clamping tables 3 and the clamped wooden boards rise to the highest position, the servo motor 2 33 is started, and its output shaft drives the connecting frame 13 to rotate 90 degrees. The connecting frame 13 drives the two clamping tables 3 to rotate 90 degrees. The two clamping tables 3 drive multiple wooden boards to descend and rotate. Multiple wooden boards are merged together from longitudinally to transversely, and are just perpendicular to the wooden boards of the first layer. When the second layer of wooden boards descends to the top of the second layer of wooden boards, the positioning clamping is cancelled to complete the second stacking process. After the clamping table 3 descends and resets, the servo motor 2 33 drives the two servo motors 2 33 to rotate in the opposite direction and reset, and 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 of wooden boards. Similarly, a mutually supporting structure is formed between the vertically alternately stacked wooden boards, which enhances the overall stability and reduces the risk of wooden boards collapsing. Through the coordinated work of the lifting assembly and the pull rope assembly, each time the wooden boards rise, the stacking table 2 will be located directly under the two clamping tables 3, ensuring the stacking accuracy, jointly promoting the efficient and stable operation of the stacking process, and improving 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 with inner sliders 17, the bottom of the crossbeam frame 14 is fixedly connected to the top of the two inner sliders 17, and the top of the fixed seats 15 is fixedly installed with a hydraulic cylinder 16, and the output end of the hydraulic cylinder 16 is fixedly connected to the top of the inner slider 17.

[0037] During operation: when the wooden board is placed between the two clamping tables 3 and is positioned and clamped by the fixing assembly, the hydraulic cylinder 16 is started, and its output shaft drives the inner slider 17 to rise. The inner slider 17 will stably move along the inner wall of the fixing seat 15 during the rising process. The inner slider 17 will drive the crossbeam frame 14 to rise during the rising process. The crossbeam frame 14 will drive the two clamping tables 3 to rise through the connecting frame 13, thereby driving several wooden boards that have been positioned and clamped close together to rise. Similarly, the hydraulic cylinder 16 can also drive the inner slider 17 to descend along the inner wall of the fixing seat 15, thereby driving the wooden board to descend.

[0038] like Figure 2 and Figure 7 As shown, the pull rope assembly includes two connecting ropes 19, and the bottoms of the two inner sliders 17 are fixedly connected to the middle parts of both sides of the stacking platform 2 with fixing rings 21, the fixing ring 21 connected to the bottom of the inner slider 17 is sleeved with a ring 18, and the fixing ring 21 connected to the side of the stacking platform 2 is sleeved with a ring 20, one end of the connecting rope 19 is fixedly connected to the outer wall of the ring 18, and the end of the connecting rope 19 away from the ring 18 is fixedly connected to the outer wall of the ring 20.

[0039] During operation: in the initial state, the connecting rope 19 remains taut, and when the inner slider 17 rises, an upward traction force is applied to one end of the connecting rope 19 through the fixed ring 21 and the ring 18 connected to its bottom, and one end of the connecting rope 19 is converted into a pulling force after being subjected to the traction force, and acts on the fixed ring 21 connected to the side of the stacking platform 2 through the ring 20, so that the stacking platform 2 moves laterally along the surface of the workbench 1, and when the inner slider 17 rises to the maximum height, the stacking platform 2 is just pulled to the bottom of the two clamping platforms 3, and the connecting rope 19 remains taut in a vertical state, so that each time the wooden board rises, the stacking platform 2 is located directly below the two clamping platforms 3, ensuring the stacking accuracy and jointly promoting the efficient and stable operation of the stacking process.

[0040] like Figure 6 to Figure 7 As shown, the upper surface of the workbench 1 is symmetrically provided with slide grooves 23, the bottom of the stacking platform 2 is symmetrically fixedly connected with pulleys 22, the pulleys 22 and the slide grooves 23 are slidably connected and adapted to each other, and a positioning assembly is provided on the outer side of the stacking platform 2, which is used to fix the moving position of the stacking platform 2.

[0041] During operation: when the inner slider 17 reaches the highest point upwards, it will drive the stacking platform 2 to move to the bottom of the two clamping platforms 3 through the connecting rope 19. At this time, under the action of the positioning assembly, the stacking platform 2 remains motionless in this position. When the inner slider 17 drives the clamping platform 3 and the wooden board to descend, the stacking platform 2 is always located directly below the clamping platform 3 and the wooden board until the wooden board falls directly above the stacking platform 2 or falls above the wooden board stacked in the previous layer.

[0042] like Figures 8 to 9 As shown, the locking assembly includes two hinged parts 24, and the two hinged parts 24 are respectively fixedly installed on both sides of the stacking platform 2. The shafts of the hinged parts 24 are hinged with hinged rods 25, and the back sides of the hinged rods 25 are fixedly connected with angle springs 27. The side of the angle spring 27 away from the hinged rod 25 is fixedly connected to the side of the stacking platform 2, and a fixed block 28 is provided on one side of the hinged rod 25.

[0043] During operation: when the inner slide 17 rises and makes the stacking platform 2 move laterally along the upper surface of the workbench 1, the hinged rod 25 will be driven to gradually approach the fixed block 28. When the outer wall of the hinged rod 25 slowly contacts the side of the fixed block 28, the hinged rod 25 will be hinged and rotated around the shaft of the hinge 24. When the hinged rod 25 is hinged and rotated, the angle spring 27 will be squeezed to deform it. At this time, the angle between the hinged rod 25 and the side of the stacking platform 2 becomes smaller, so that the hinged rod 25 can smoothly pass through one side of the fixed block 28. When the stacking platform 2 moves to the bottom of the wooden board, At this time, the end of the hinged rod 25 away from the hinged part 24 just moves to one side of the fixed block 28, and the angle spring 27 recovers its deformation so that the end of the hinged rod 25 away from the hinged part 24 just fits with one side of the fixed block 28. Under the restriction of the fixed block 28, when the inner slider 17 descends, the position of the entire stacking platform 2 will not change, and the connecting rope 19 remains in a loose state between the two parties during the descent process, so as to ensure that the wooden boards between the two clamping platforms 3 can accurately fall onto the previous layer of stacked wooden boards above the stacking platform 2, thereby 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 the 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 fixed block 28 is provided with a pulling component that drives the fixed block 28 to move.

[0045] During operation: when the end of the hinged rod 25 away from the hinged part 24 just fits with one side of the fixed block 28, under the restriction of the limit rod 26, when the stacking platform 2 is subjected to backward pulling force, the hinged rod 25 and the hinged part 24 will not be hinged and rotated, and the angle spring 27 will not be stretched to increase the angle between the hinged rod 25 and the side of the stacking platform 2. In addition, through the setting of the pulling assembly, the fixed block 28 is moved and no longer keeps in contact with one end of the hinged 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 and 10As shown, the pulling assembly includes two mounting seats 30, the inner walls of the mounting seats 30 are slidably connected with movable blocks 29, the movable blocks 29 are fixedly connected to the bottom of the fixed block 28, one end of the movable block 29 is fixedly connected with a return spring 31, the other end of the return spring 31 is fixedly connected to the inner wall of the mounting seat 30, the fixed block 28 is made of iron material and a through electromagnet 32 ​​is provided on one side, the through electromagnet 32 ​​is fixedly installed on the top of the workbench 1, and the elastic hardness of the return spring 31 is much greater than the elastic hardness of the hinged rod 25.

[0047] During operation: when the wooden boards are stacked, current is passed through the electromagnet 32, which can absorb the fixed block 28 of the iron material. After the fixed block 28 is attracted by the electromagnet 32, it will slide along the inner wall of the mounting seat 30 through the movable block 29 and squeeze the reset spring 31, so that the fixed block 28 is no longer in contact with one end of the hinged rod 25, which is convenient for the subsequent reset of the entire stacking platform 2. Since the elastic hardness of the reset spring 31 is much greater than the elastic hardness of the hinged rod 25, when the hinged rod 25 moves along the side of the fixed block 28, it will only squeeze the angle spring 27 to cause it to deform, and the hinged rod 25 will not push the fixed block 28 to squeeze the reset spring 31 to move; after the stacking platform 2 is reset, the electromagnet 32 ​​is powered off. At this time, under the action of the reset spring 31, the fixed block 28 moves in the opposite direction and resets to prepare for the next work.

[0048] like Figure 6 As shown, a movable pulley 34 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 a movable pulley 34 is fixedly installed on the top of the workbench 1, and the movable pulley 34 is slidably connected to the connecting rope 2 35.

[0049] During operation: when the inner slide block 17 rises and the stacking platform 2 moves horizontally, the counterweight block 36 will be pulled to make it move upward. When the stacking platform 2 moves to the bottom of the two clamping platforms 3 and the wooden boards, the position of the stacking platform 2 will not change under the action of the positioning assembly, but the stacking platform 2 will always be subjected to the pulling force of the counterweight block 36 on one side. When the assembly is pulled apart so that the fixed block 28 no longer maintains a fit with one end of the hinged rod 25, under the action of the counterweight block 36, the stacking platform 2 can automatically move in the opposite direction to the initial position, and the connecting rope 19 can be kept taut again, and the entire device returns to the initial position, thereby facilitating the stacking of the next layer of wooden boards.

[0050] like Figure 3 to Figure 4As shown, the fixing assembly includes a plurality of articulated seats 4, and the plurality of articulated seats 4 are fixedly mounted on the inner wall of the clamping table 3, the shafts of the plurality of articulated seats 4 are hinged with support members 5, and the number of the plurality of support members 5 corresponds one by one to the number of wooden boards, the tops of the shafts of the plurality of articulated seats 4 are fixedly connected with transmission rings 10, and transmission belts 11 are fixedly connected between the outer walls of the plurality of transmission rings 10, and a servo motor 12 is fixedly mounted on the top of the clamping table 3, and 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 are used to support the bottom of multiple wooden boards. When multiple wooden boards are about to fall to the top of the stacking platform 2 or the top of the upper layer of wooden boards, the servo motor 12 is started, which will drive one of the transmission rings 10 to rotate through the output shaft, and the transmission ring 10 will drive multiple transmission rings 10 to rotate through the transmission belt 11, so that the support member 5 is hinged and rotated with the shaft of the hinge seat 4 as the center point, so that the multiple support members 5 are all rotated into the inside of the clamping platform 3, and no longer support the bottom of the wooden boards, so that multiple wooden boards fall to the top of the stacking platform 2 or the top of the upper layer of wooden boards.

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

[0053] During operation: when multiple wooden boards are placed between the two clamping tables 3, the two electric slide blocks 7 are controlled to move closer to each other along the inner wall of the electric slide rail 6, so that the two groups 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 fitted together, and each wooden board is located directly above each support member 5 and corresponds to each other. The positions of the multiple wooden boards in each layer are proofread. When multiple wooden boards fall onto the upper layer of wooden boards, there will be no positional offset between the upper layer of wooden boards, so that each side of the wooden boards is in a flat state after stacking, thereby improving the stability of stacking.
