Description

Technical Field

[0001] This utility model relates to the field of plate handling technology, and in particular to a single-plate extraction machine. Background Technology

[0002] Post-processing of engineered wood panels includes processes such as panel screening, cooling, and stacking. The stacking process involves initially stacking the continuously input panels into a designated height, such as a 1.5m high stack, and then transferring this stack to a warehouse for further stacking into even higher stacks, such as 6m high, for storage. The initial small-height stacks typically weigh over 1 ton, while larger panels can weigh over 3 tons. During the transfer to the warehouse, roller conveyors or multiple chain conveyors are commonly used, involving multiple turns. During these processes, the bottom panel in the small-height stack is highly susceptible to scratches and impacts due to the weight of the stack, resulting in product loss. Furthermore, for thin panel stacks, the lack of adequate support during warehouse transfer can easily lead to bending and deformation.

[0003] To improve the above situation, the inventors considered adding a pad at least at the bottom of the stack of thin plates in low-height stacks to protect the plates and provide full load-bearing support during transportation, reducing plate deformation. The bottom pad needs to be laid before stacking the plates. In practice, the pads are transported to the stacking equipment in stacks, and one pad is taken from the stack when needed. Initially, the inventors considered using a gripping robot to pick up the top pad from the stack and move it to the designated location on the stacking equipment. However, this gripping robot is complex and costly. For tasks where only one pad is placed and damage or deformation is not critical, its economic viability is unlikely to be accepted by the user. Therefore, the inventors designed and manufactured a single-plate extraction machine to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a single-board extraction machine that is simple to operate and low in cost.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a single board extraction machine, including a frame, a board stacking platform on the frame, a board stack blocking structure on the frame above the board output end of the board stacking platform, and a single board output gap between the board stack blocking structure and the board stacking platform; a circulating push chain installed on the frame at the board stacking platform, extending beyond the board stack blocking structure, the circulating push chain being connected to a push driver, and a pusher body installed on the circulating push chain, extending above the board stacking platform, the pusher body being used to push the bottom board in the stack of pads past the board stack blocking structure.

[0006] As a preferred technical solution, the board stack blocking structure includes a gantry frame fixedly installed on the frame and located at the board output end of the board stacking platform. A board stack baffle is fixedly installed on the gantry frame, and a single board output gap is provided between the board stack baffle and the board stacking platform.

[0007] As a preferred technical solution, a gap adjustment device is provided between the plate stack baffle and the gantry frame.

[0008] As a preferred technical solution, the gap adjustment device includes a connecting screw hole provided on the plate stack baffle, and a vertical elongated hole is provided on the side of the plate stack baffle away from the pad stack on the gantry frame, and a position fixing bolt installed on the connecting screw hole is inserted through the vertical elongated hole.

[0009] As a preferred technical solution, a positioning plate extending laterally to the top of the plate stack baffle is fixedly provided, and a positioning bolt is installed through the positioning screw hole on the positioning plate, with the lower end of the positioning bolt abutting against the gantry.

[0010] As a preferred technical solution, the frame is provided with a plate stack side positioning structure on one side of the plate stacking platform.

[0011] As a preferred technical solution, the board stacking platform is provided with a board placement clearance opening at the board receiving end.

[0012] As a preferred technical solution, the frame is provided with a chain protection structure on the side of the feed plate of the circulating push chain.

[0013] Due to the adoption of the above technical solution, the single-board extraction machine includes a frame, on which a board stacking platform is provided. A board stack blocking structure is provided on the frame above the board output end of the board stacking platform, and a single-board output gap is provided between the board stack blocking structure and the board stacking platform. A circulating push chain, positioned above the board stacking platform, is installed on the frame at the board stacking platform. This chain is connected to a push driver, and a pusher body, positioned above the board stacking platform, is installed on the circulating push chain. This pusher body is used to push the bottom board of the board stack past the board stack blocking structure. The board stack from other processes is placed on the board stacking platform, and the pusher body is initially located on the board input side of the board stack. When a pad is needed, the pusher drives the circulating push chain, and the pusher body begins to push the bottom pad. The remaining pads above are rigidly blocked by the stacked plate blocking structure, preventing them from moving. Therefore, only the bottom pad is ultimately pushed out from the single-plate exit gap, achieving the purpose of single-plate extraction. The entire device uses only the pusher drive for power, and the single-plate extraction action is completed simply by driving the pusher body in a straight line. The operation is simple and cost-effective. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the single-board extraction machine includes a frame 1, on which a board stacking platform 2 is provided for placing a stack of pad boards 9. A board stack blocking structure 3 is provided on the frame 1 above the board output end of the board stacking platform 2, and a single-board output gap 31 is provided between the board stack blocking structure 3 and the board stacking platform 2. A circulating push chain 4 is installed on the frame 1 at the board stacking platform 2, extending beyond the board stack blocking structure 3. Of course, the circulating push chain 4 does not exceed the board stacking platform 2. The circulating push chain 4 is connected to a push driver 41. A push body 5 is installed on the circulating push chain 4, extending beyond the board stacking platform 2. The push body 5 is used to push the bottom pad board 91 of the stack of pad boards 9 past the board stack blocking structure 3.

[0021] In this embodiment, the pad stack 9 from other processes is placed on the stack placement platform 2, and the pusher 5 is initially located at the receiving side of the pad stack 9. When a pad 91 is needed, the pusher driver 41 drives the circulating pusher chain 4, and the pusher 5 begins to push the bottom pad 91. The remaining pads 91 above cannot move due to the rigid obstruction of the stack blocking structure 3, so only the bottom pad 91 is ultimately pushed out from the single-board exit gap 31 for use, achieving the purpose of single-board extraction. The extracted pad 91 is pushed to the stacking platform of the stacking equipment by the pusher 5, and the stacking platform continues to receive it. The pusher driver 41 drives the circulating pusher chain 4 to continue running, and the pusher 5 eventually returns to the receiving side of the pad stack 9 along the circulating path of the circulating pusher chain 4, waiting to extract the next pad 91. The entire device uses only one power source, the push driver 41, and the single-board extraction action can be completed simply by driving the push body 5 to push it linearly. The action is simple and the cost is low.

[0022] In this embodiment, the definitions of "outgoing plate end," "outgoing plate side," "coming plate end," and "coming plate side" refer to the side from which the plate is output as the outgoing plate side, and the end of the related structure corresponding to that side as the outgoing plate end. The side opposite to the outgoing plate side is the coming plate side, and the end of the related structure corresponding to that side as the coming plate end. This embodiment uses these definitions to more clearly explain the structural principle and is not intended to limit the scope of protection.

[0023] In this embodiment, the pusher 5 is implemented with a block structure. In actual setup, single-board extraction using at least two-point pushing can improve pushing force and stability. Therefore, the circulating push chain 4 in this embodiment is preferably set to at least two chains, and four chains are shown in the attached figure. The pusher 5 is respectively installed on the four circulating push chains 4 to form a four-point push on the bottom pad 91. One of the four circulating push chains 4 is mounted on a sprocket and coaxially connected to the push driver 41 to form a synchronous drive.

[0024] In this embodiment, the plate stacking platform 2 is composed of multiple stacking sub-platforms 21 arranged in parallel along the pushing direction. A certain space outside the platform is formed between adjacent stacking sub-platforms 21 and outside the two outermost stacking sub-platforms 21. The circulating pushing chain 4 is installed in this space outside the platform.

[0025] In practical use, the pallet stack 9 can be transported by forklifts or other equipment. Therefore, the pallet stacking platform 2 in this embodiment has a pallet clearance opening 22 at its receiving end to avoid forklift forks and other structures, ensuring that the forklift can smoothly place the pallet stack 9 onto the pallet stacking platform 2. Since the pallet stacking platform 2 in this embodiment has a structure with multiple external spaces, these external spaces can also serve as the pallet clearance opening 22.

[0026] Preferably, a chain protection structure 6 is provided on the frame 1 at the side of the circulating push chain 4 where the pallet is being delivered, to prevent forklifts or other vehicles from bumping into the circulating push chain 4 and causing structural damage. In this embodiment, the chain protection structure 6 is a vertical structure with two symmetrical guide ramps, which can be directly machined from angle steel.

[0027] Preferably, a stack side positioning structure 7 is provided on one side of the stacking platform 2 on the frame 1. Combined with the blocking and limiting effect of the stack blocking structure 3, when the pad stack 9 is transported, the stack side positioning structure 7 and the stack blocking structure 3 can directly limit its position on the adjacent sides of the pad stack 9, ensuring relatively accurate placement of the pad stack 9 on the stacking platform 2. This facilitates the rapid formation of pads after the individual boards are extracted, ensuring they roughly correspond to the stacking positions on the stacking equipment. The stack side positioning structure 7 can also be implemented using a baffle fixedly mounted on the frame 1.

[0028] The plate stack blocking structure 3 described in this embodiment includes a gantry frame 32 fixedly installed on the frame 1 and located at the plate output end of the plate stacking platform 2. A plate stack baffle 33 is fixedly installed on the gantry frame 32, and a single plate output gap 31 is provided between the plate stack baffle 33 and the plate stacking platform 2.

[0029] Preferably, a gap adjustment device is provided between the stack baffle 33 and the gantry frame 32 to fine-tune the single-board exit gap 31 to accommodate pads 91 of different thicknesses. In this embodiment, the gap adjustment device includes a connecting screw hole 34 on the stack baffle 33, and a vertical elongated hole 35 on the side of the gantry frame 32 away from the stack baffle 33. A position fixing bolt 36, mounted on the connecting screw hole 34, passes through the vertical elongated hole 35. After loosening the position fixing bolt 36, the stack baffle 33 can move up and down along the vertical elongated hole 35. After moving to the desired position, the single-board exit gap 31 reaches the required size. The position fixing bolt 36 is then retightened to fix the stack baffle 33, achieving the gap adjustment purpose. Preferably, multiple sets of the connecting screw hole 34, the vertical elongated hole 35, and the position fixing bolt 36 are provided to improve the stability of the stack baffle 33.

[0030] Furthermore, a positioning plate 37 extending laterally above the gantry frame 32 is fixedly provided on the top of the plate stack baffle 33. A positioning bolt 38 is installed through a positioning screw hole on the positioning plate 37, and the lower end of the positioning bolt 38 abuts against the gantry frame 32. When the position fixing bolt 36 is loosened and the positioning bolt 38 is tightened, the height of the positioning plate 37 will change, and the height of the plate stack baffle 33 will change accordingly. After the height of the plate stack baffle 33 reaches the specified height, the position fixing bolt 36 is tightened again to fix the plate stack baffle 33, thereby achieving the purpose of adjusting the gap by engaging the positioning bolt 38. Furthermore, after the plate stack baffle 33 is re-fixed, the positioning bolt 38 simultaneously forms a rigid restriction on the downward direction of the plate stack baffle 33. Thus, when a single pad 91 is extracted and the pad stack 9 descends, it can effectively prevent the pad stack 9 from causing the plate stack baffle 33 to descend and affecting the subsequent single-sheet extraction action.

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.
