Description

Technical Field

[0001] This utility model relates to the field of board stacking technology, and in particular to a high-height stacking machine for artificial boards. Background Technology

[0002] Engineered wood products (AW) are made from wood fibers or shavings, bonded together with adhesives, and are widely used in construction, furniture, and packaging. The production process generally includes three parts: raw material preparation, bonding and molding, and post-processing. The post-processing mainly involves cooling and stacking the finished panels. In most cases, finished panels need to be stacked to a height of about two meters or even higher before being transported and stored. Currently, the post-processing process is largely automated, resulting in high efficiency. Conventional machines that use negative pressure to lift panels for high-height stacking have long lifting and retraction times, making their efficiency incompatible with automated post-processing operations, and they have been gradually phased out. The current stacking method involves pre-stacking the panels into smaller stacks, then sequentially stacking these smaller stacks into larger stacks. Each pre-stacking of a smaller stack allows time for the subsequent stacking of the larger stack, thus enabling continuous and coordinated stacking operations in the post-processing process. However, due to the large size and high density of engineered wood panels, even small-height stacks are relatively large in volume and weight. Therefore, extremely high stability is required during the lifting and retracting movements of the stacking equipment. Otherwise, even with pre-stacking buffering of small-height stacks, it is difficult to quickly complete large-height stacking operations, and the stacking quality will be unsatisfactory. Therefore, improvements to the large-height stacking equipment are necessary. Utility Model Content

[0006] As a preferred technical solution, the receiving platform includes a frame with a receiving support surface. Side frames that extend above the receiving support surface are fixedly installed on the frame near each of the machine body columns. Pushing support beams are fixedly installed between the tops of the two side frames near the stacking platform and between the tops of the two side frames away from the stacking platform. Two pushing installation beams are fixedly installed between the two pushing support beams, forming a receiving space between the pushing installation beams and the receiving support surface. The pushing device is installed on the two pushing installation beams.

[0007] As a preferred technical solution, the pushing device includes a pushing frame movably mounted on the two pushing mounting beams along its length. Several pushing upright plates are fixedly arranged perpendicular to the pushing direction on the pushing end of the pushing frame. Pushing transmission racks are fixedly mounted on the two pushing mounting beams respectively. Two pushing transmission gears that are constantly meshed with the two pushing transmission racks are rotatably mounted on the pushing frame. A pushing drive motor is installed in the middle of the pushing frame. A cross transmission shaft is connected between the power end of the pushing drive motor and the two pushing transmission gears respectively.

[0008] As a preferred technical solution, the platform is fixedly provided with a plurality of plate-receiving support plates arranged in parallel along the pushing direction, and the top surfaces of the plate-receiving support plates together constitute the plate-receiving support surface; the lower end of the pushing upright plate extends between two adjacent plate-receiving support plates.

[0009] As a preferred technical solution, the stacking platform includes a stacking frame, on which a plurality of stacking rollers are arranged and installed perpendicular to the pushing direction, and the stacking rollers are connected to a side output driver.

[0010] As a preferred technical solution, a pushing limit device is provided on the side of the stacking platform away from the receiving platform.

[0011] As a preferred technical solution, the push limiting device includes limiting brackets fixedly arranged relative to the four machine body columns. Two vertically arranged limiting transmission shafts are rotatably mounted on the limiting brackets. A limiting transmission frame is fixedly arranged on each of the limiting transmission shafts. A limiting frame is hingedly installed between the ends of the two limiting transmission frames near the stacking platform. A parallelogram mechanism is formed between the limiting frame and the two limiting transmission frames. A limiting part for limiting the push position is fixedly arranged on the limiting frame. A limiting position adjuster is provided between the limiting transmission frame and the limiting bracket.

[0013] Due to the adoption of the above technical solution, the high-height stacker for engineered wood products includes four rectangularly arranged machine columns. A top worktable is fixedly connected to the top of each machine column, and a lifting and movable receiving platform is installed between the four machine columns. A lifting drive shaft is rotatably mounted on the top worktable, and the lifting drive shaft is connected to a lifting driver. Two side drive sprockets are respectively installed at both ends of the lifting drive shaft.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0026] like Figure 1 As shown, the high-height stacker crane for engineered wood products includes four rectangularly arranged machine columns 1. A top worktable 11 is fixedly connected to the top of each of the four machine columns 1. A lifting and movable pallet receiving platform 2 is installed between the four machine columns 1. The lifting and movable installation of the pallet receiving platform 2 can be achieved using one or more of the following methods: wheel-rail system, guide rail slide, guide rod slide, etc. No limitation is imposed here. Figure 3As shown, this embodiment is achieved by setting lifting guide wheels 21 at at least two adjacent sides of each of the machine body columns 1, that is, by using the machine body columns 1 as the rail in a wheel-rail manner.

[0027] like Figure 1 As shown, a lifting drive shaft 3 is rotatably mounted on the top worktable 11, and the lifting drive shaft 3 is connected to a lifting driver 31. Conventionally, the lifting driver 31 includes a lifting drive motor and a lifting reducer, and the output end of the lifting reducer is poweredly connected to the lifting drive shaft 3. When the lifting drive motor drives the lifting drive shaft 3 to rotate forward, the receiving platform 2 rises; when it rotates in reverse, it drives the receiving platform 2 to descend.

[0028] like Figures 1 to 5 As shown, two side drive sprockets 32 are respectively installed at both ends of the lifting drive shaft 3. A top drive sprocket 33 is installed at the upper end of each of the machine body columns 1, and a bottom drive sprocket 34 is installed at the lower end. Lifting drive chains 35 are respectively installed between the two side drive sprockets 32 at the same end and the top drive sprockets 33 and bottom drive sprockets 34 on the corresponding two machine body columns 1. When the lifting drive shaft 3 is driven to rotate, the four lifting drive chains 35 can move synchronously at the same speed. In this embodiment, there are two top drive sprockets 33 installed on different shafts. The lifting drive chain 35 passes around the higher top drive sprocket 33, then goes down around the bottom drive sprocket 34 and back, then passes around the lower top drive sprocket 33 and connects with the corresponding side drive sprocket 32. This achieves the setting of a single lifting drive chain 35. When the lifting drive chain 35 is tensioned, the lifting drive shaft 3 can switch between forward and reverse rotation without delay. The structure is simple and the transmission accuracy is high.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, chain connection structures 4 are fixedly provided on the receiving platform 2 at the positions corresponding to the positions of the machine body columns 1. The chain connection structures 4 are respectively connected to the same direction section of the lifting transmission chain 35 on the corresponding machine body columns 1, thereby realizing the lifting drive 31 to lift the receiving platform 2.

[0030] Preferably, the chain connection structure 4 includes two chain end fixing seats 41 arranged vertically. Each chain end fixing seat 41 is vertically fitted with a chain end connecting stud 42. A chain tensioning nut 43 is installed on the near end of each of the two chain end connecting studs 42. A chain end hinge seat 44 is fixedly connected to the far end of each of the two chain end connecting studs 42. A chain end connecting block 45 is installed on each of the chain end hinge seats 44. The chain end connecting block 45 is connected to the link of the lifting transmission chain 35. A hinge connecting pin 46 is inserted between the end of the chain end connecting block 45 away from the lifting transmission chain 35 and the chain end hinge seat 44. The hinge connecting pin 46 is perpendicular to the link connecting pin of the lifting transmission chain 35.

[0031] During installation, the lifting transmission chain 35 is wound around the corresponding side transmission sprocket 32, top transmission sprocket 33, and bottom transmission sprocket 34. Both ends of the lifting transmission chain 35 are connected to two chain end connecting blocks 45, which are hinged to chain end hinge seats 44. The chain tension nut 43 is rotated towards the corresponding chain end hinge seat 44 to tension the lifting transmission chain 35. After tensioning, self-locking is achieved through the helical connection between the chain tension nut 43 and the chain end connecting stud 42. In actual installation, two chain tension nuts 43 can also be installed on each chain end connecting stud 42 for better locking. After the lifting transmission chain 35 is tensioned, there is no delay in the switching of lifting transmission. The hinged connection between the chain end connecting block 45 and the chain end hinge seat 44 can avoid the influence of the assembly position error between the lifting transmission chain 35 and the chain end hinge seat 44, and ensure that the lifting transmission chain 35 can drive smoothly and accurately.

[0032] like Figure 6 As shown, a stacking platform 5 is provided on one side of the receiving platform 2. A pushing device 6 for pushing boards onto the stacking platform 5 is installed on the receiving platform 2. During operation, a small-height stack of boards is input onto the receiving platform 2. This small-height stack is neatly stacked during pre-stacking and is pushed as a whole onto the receiving platform 2 to a fixed position. Then, the lifting driver 31 drives the receiving platform 2 to rise to a specified height, where the height of the small-height stack on the receiving platform 2 is slightly higher than the height of the stack on the stacking platform 5. The pushing device 6 pushes the small-height stack on the receiving platform 2 onto the top of the stack on the stacking platform 5, achieving the stacking purpose. After pushing, the pushing device 6 returns to its original position, and the lifting driver 31 drives the receiving platform 2 to descend to its initial position, waiting to receive the next small-height stack.

[0033] like Figures 1 to 6As shown, the receiving platform 2 in this embodiment includes a frame 22, on which a receiving support surface 23 is provided. The input stack of small-height plates is supported on the receiving support surface 23. Side frames 24, which are higher than the receiving support surface 23, are fixedly provided on the frame 22 near each of the machine body columns 1. The side frames 24 are also the parts on the receiving platform 2 where the lifting guide wheels 21 and the chain connection structure 4 are installed. Pushing support beams 25 are fixedly provided between the tops of the two side frames 24 near the stacking platform 5 and between the tops of the two side frames 24 away from the stacking platform 5. Two pushing installation beams 26 are fixedly provided between the two pushing support beams 25 to form a strong frame structure. A receiving space is formed between the pushing installation beams 26 and the receiving support surface 23. The pushing device 6 is installed on the two pushing installation beams 26. The stack of small-height plates is input from one of the two sides of the pushing direction to the receiving support surface 23.

[0034] like Figure 6 and Figure 9 As shown, the pushing device 6 includes a pushing frame 61 movably mounted on two pushing mounting beams 26 along its length. Several pushing uprights 62 arranged perpendicular to the pushing direction are fixedly provided on the pushing end of the pushing frame 61. Pushing transmission racks 63 are fixedly provided on each of the two pushing mounting beams 26. Two pushing transmission gears 64, which are normally meshed with the two pushing transmission racks 63, are rotatably mounted on the pushing frame 61. A pushing drive motor 65 is installed in the middle of the pushing frame 61. A cross drive shaft 66 connects the power end of the pushing drive motor 65 to each of the two pushing transmission gears 64. When the pushing drive motor 65 drives the two pushing transmission gears 64 to rotate clockwise, the pushing frame 61 moves towards the stacking platform 5, and the pushing uprights 62 push the small-height stack of plates on the receiving platform 2 onto the stacking platform 5. When the pushing drive motor 65 drives the two pushing transmission gears 64 to rotate counterclockwise, the pushing frame 61 returns to its original position.

[0035] Preferably, the platform 22 is fixedly provided with a plurality of receiving support plates 27 arranged side by side along the pushing direction, and the top surfaces of the receiving support plates 27 together constitute the receiving support surface 23; the lower end of the pushing upright plate 62 extends between two adjacent receiving support plates 27. In this way, while ensuring support for small-height stacks of plates, the pushing upright plate 62 can extend to the bottom of the small-height stacks to form a pushing mechanism, making the pushing more reliable, and reducing the influence of the height difference between the receiving support surface 23 and the stacks on the stacking platform 5, thus ensuring smooth pushing.

[0036] like Figure 1 and Figures 6 to 8As shown, preferably, a pushing limiting device 7 is provided on the side of the stacking platform 5 away from the receiving platform 2 to position the small-height stacks pushed onto the stacking platform 5, ensuring neat stacking and guaranteeing that the small-height stacks are pushed to a designated position above the stacking platform 5. In this embodiment, the pushing limiting device 7 includes limiting brackets 71 fixedly arranged relative to the four machine body columns 1. Two vertically arranged limiting transmission shafts 72 are rotatably mounted on the limiting brackets 71. Each limiting transmission shaft 72 is fixedly provided with a limiting transmission frame 73. A limiting frame 74 is hinged between the ends of the two limiting transmission frames 73 near the stacking platform 5, forming a parallelogram mechanism between the limiting frame 74 and the two limiting transmission frames 73. A limiting part 75 for limiting the pushing position is fixedly provided on the limiting frame 74. A limiting position adjuster 76 is provided between the limiting transmission frame 73 and the limiting bracket.

[0037] The limiting part 75 in this embodiment includes four limiting rods arranged perpendicular to the pushing direction, which together form a limiting surface. By changing the shape of the parallelogram through the limiting position adjuster 76, the limiting position of the limiting part 75 is changed to accommodate different sized plates for limiting use, so that plates of different sizes can be stacked to the center or near the center of the stacking platform 5, which is beneficial for the smooth output of large stacks of plates.

[0038] The limit position adjuster 76 includes a limit position adjusting sleeve 77, with limit position adjusting screws 78 threadedly connected to both ends of the sleeve 77. The threads of the two limit position adjusting screws 78 are arranged in opposite directions. One limit position adjusting screw 78 is hinged to the limit bracket 71, and the other is hinged to the limit transmission frame 73. By rotating the limit position adjusting sleeve 77 in the forward direction, the two limit position adjusting screws 78 are brought closer together, deforming the parallelogram mechanism. The limiting part 75 moves away from the stacking platform 5 and is adjusted to the desired position, then locked in place by the self-locking property of the screw sleeve. Conversely, rotating the limit position adjusting sleeve 77 in the reverse direction adjusts the limiting part 75 towards the stacking platform 5. Each of the limit position adjusting screws 78 is equipped with a limit position locking nut 79. After adjustment, the limit position locking nut 79 is tightened to the corresponding end of the limit position adjusting screw sleeve 77 to improve the reliability of the limit position locking.

[0039] like Figure 6As shown, preferably, the stacking platform 5 includes a stacking frame 51, on which a plurality of stacking rollers 52 are arranged perpendicular to the pushing direction. The stacking rollers 52 are connected to a side output driver. The stacking platform 5 is supported by the plurality of stacking rollers 52, and after the plates are stacked on it to the required height, the side output driver drives the stacking rollers 52 to roll, outputting the stacked plates to one side, thus forming an automatic stacking output operation.

[0040] In this embodiment, the lifting transmission chain 35 is installed using the lifting transmission shaft 3, side transmission sprocket 32, top transmission sprocket 33, and bottom transmission sprocket 34. This allows one lifting driver 31 to provide synchronous lifting drive to the four corners of the receiving platform 2, enabling smooth lifting even when the receiving platform 2 is carrying a large, heavy stack of small-height boards. With this smooth lifting, the built-in pushing device 6 on the receiving platform 2 can quickly push the small-height stacks onto the stacking platform 5. The stacking process is smooth and fast, with good stacking quality, facilitating continuous stacking operations.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
