Description

Technical Field

[0001] This invention relates to the field of sheet metal storage and stacking, specifically to a dense sheet metal stacking and retrieving device that avoids deformation during stacking. Background Technology

[0002] Currently, common equipment for storing and stacking the same batch of sheet materials is mainly based on fixed-height structures, such as fixed-height steel shelves suitable for large quantities of sheet materials from the same batch, fixed-support stacking racks suitable for small and medium-sized sheet materials from the same batch, and ground-mounted fixed stacking racks suitable for temporary stacking of sheet materials from the same batch. These are the most widely used and common equipment in the industry. They can be used in industrial workshops, warehouses, and other places to store and stack sheet materials from the same batch, that is, sheet materials with the same production batch and uniform specifications, including thickness, width, length, material, and surface treatment. This enables centralized management, damage-free preservation, and convenient access, which is a common requirement in the industrial sheet material processing and warehousing industry.

[0003] The existing board stacking devices of the same batch are mostly fixed height structures. In order to improve space utilization, the boards need to be stacked in the upper area of ​​the device. However, since the height of the device is fixed, when workers want to stack the boards in the upper area, they need to climb to the corresponding height to operate. This is not only labor-intensive, but also poses a safety hazard of falling from height. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a dense board stacking and retrieval device that avoids deformation during stacking, solving the problem of high labor intensity and safety hazards associated with climbing to operate at heights.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a dense board stacking and retrieving device that avoids deformation during stacking, comprising two vertically arranged slide rails and a plurality of sliders slidably mounted on the slide rails.

[0006] The sliders are symmetrically distributed in pairs on two slide rails. Each pair of sliders is provided with a support plate. The upper and lower surfaces of the support plate are provided with several slots. A traction rope is installed between each pair of adjacent sliders. Several support plates are arranged from top to bottom along the height direction of the slide rail.

[0007] In the initial state, several sliders are attached and stacked together, so that the support plate is in a low position. When the uppermost slider and the corresponding support plate are lifted along the slide rail by force, a gap is formed between the two adjacent support plates through the traction rope for vertical placement of the plate, and the plate is clamped between the two adjacent support plates through the slot.

[0008] Preferably, a base plate is fixedly connected to the bottom of each of the two slide rails, and a triangular bracket is fixedly installed on the base plate. The two triangular brackets are respectively fixedly connected to the two slide rails.

[0009] Preferably, the support plate includes two plates and two connectors, with slots disposed within the plates and the two plates connected by the connectors.

[0010] Preferably, each slider is fixedly connected to a fixed bracket, the end of the plate near the fixed bracket has an annular cross section, and the fixed brackets close to it are rotatably connected by a rotating shaft.

[0011] Preferably, each of the slots is fixedly installed with a protective pad that is compatible with it, and the protective pad is used to contact the plate.

[0012] Preferably, winches are installed on both base plates, and stationary pulleys are respectively provided above the two slide rails. The traction wire rope of the winch passes upward around the corresponding stationary pulley, and the end of the traction wire rope is fixedly connected to the uppermost slider.

[0013] Preferably, the bearing plate is made of rigid hard plate.

[0014] Preferably, the winch pulls the overall slider and the bearing plate up along the slide rail, so that a passageway is formed between the lowest bearing plate and the ground.

[0015] Preferably, the width of the bearing plate is not less than the width of the plate.

[0016] Preferably, the traction rope is installed on the side of the slider, and the installation position of the traction rope is offset from the contact surface between the slider and the traction rope.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This dense board stacking and retrieval device, which avoids deformation during stacking, has all sliders overlapping each other in the initial state, with the support plate naturally in a low position. Workers can complete the entire board loading operation while standing, without the need for climbing or using auxiliary tools such as ladders or scaffolding. This avoids the safety risks of climbing for stacking and retrieving materials. The entire loading process is completed in a low position, eliminating the need to carry heavy objects uphill, significantly reducing physical exertion. It is especially suitable for stacking large quantities of boards in the same batch, significantly improving stacking efficiency and avoiding the problems of low efficiency and fatigue associated with traditional high-level operations.

[0019] 2. This dense board stacking and retrieval device, which avoids deformation during stacking, places the boards vertically through slots, allowing their own weight to be transferred vertically along the board surface. This eliminates the surface pressure of upper boards on lower boards that occurs in traditional horizontal stacking, effectively preventing bending, sagging, and indentation damage, and significantly reducing board storage losses. The multiple slots create gaps between boards, as well as gaps formed by the length limit of adjacent support boards through traction ropes, preventing large-area adhesion between boards. This not only prevents adhesion caused by negative pressure adsorption, but also facilitates material loading and unloading while avoiding interlayer friction and scratches.

[0020] 3. This densely packed board stacking and retrieving device, which avoids deformation during stacking, allows the winch to pull the entire slider and bearing plate upwards along the slide rail after all the boards are loaded. This creates a sufficient passageway between the bottom bearing plate and the ground, achieving dual utilization of the upper storage area and the lower passageway. This avoids the problems of traditional devices occupying passageways and affecting operations. In the idle state, the detachable connectors allow the bearing plate to naturally droop and retract under its own weight, significantly reducing the overall space occupied by the device. The freed-up space can be flexibly used to stack other materials, further improving the overall utilization rate of the site. Attached Figure Description

[0032] like Figures 1-10 As shown, a dense board stacking and retrieving device that avoids deformation during stacking includes two vertically arranged slide rails 1 and several sliders 2 slidably mounted on the slide rails 1. The bottom of each of the two slide rails 1 is fixedly connected to a base plate, which can be fixed on the floor of the storage room. Triangular brackets 6 are fixedly installed on the base plate, and the two triangular brackets 6 are respectively fixedly connected to the two slide rails 1, thereby improving the stability of the slide rails 1.

[0033] Slider 2 are symmetrically distributed in pairs on two slide rails 1. A support plate 3 is provided between each pair of sliders 2. The support plate 3 is made of rigid, hard plate material, such as carbon steel or alloy steel. The width of the support plate 3 is not less than the width of the plate material. Several slots 4 are formed on the upper and lower surfaces of the support plate 3. A protective pad 8 is fixedly installed in each slot 4, and the protective pad 8 is used to contact the plate material. A detachable and replaceable traction rope 5 is installed between every two adjacent sliders 2. Several support plates 3 are arranged sequentially from top to bottom along the height direction of the slide rails 1. Each support plate 3 includes two plate bodies 301 and two connecting pieces 302. The slots 4 are located within the plate bodies 301. The two plate bodies 301 are joined together by the connecting pieces 302. Both connecting pieces 302 are fixed to the two plate bodies 301 by bolts. A fixed bracket 7 is fixedly connected to each slider 2. The end of the plate body 301 closest to the fixed bracket 7 has an annular cross-section, and the fixed bracket 7 closest to it... The components are connected by a rotating shaft. When the plates are not needed, the connecting piece 302 can be removed, and the plate 301 can naturally droop and retract, greatly reducing the overall space occupied by the device. The freed-up area can be used to flexibly stack other materials, effectively improving the utilization rate of the site space. Two winches 9 are installed on the two base plates, and two static pulleys 10 are respectively provided above the two slide rails 1. The traction steel wire rope of the winch 9 passes upward around the corresponding static pulley 10, and the end of the traction steel wire rope is fixedly connected to the uppermost slider 2. The static pulley 10 can be firmly fixed to the top of the storage room to cooperate with the winch 9 to complete the traction and lifting of the slider 2. The winch 9 pulls the entire slider 2 and the bearing plate 3 to rise along the slide rail 1, so that the lowermost bearing plate 3 forms a passage between the ground and the ground. The traction rope 5 is installed on the side of the slider 2. The installation position of the traction rope 5 is staggered from the contact surface between the sliders 2, so that adjacent sliders 2 can directly contact each other. The traction rope 5 will not interfere with the contact between the sliders 2.

[0034] In the initial state, several sliders 2 are attached and stacked together, so that the support plate 3 is in a low position. When the uppermost slider 2 and the corresponding support plate 3 are lifted along the slide rail 1 under force, the traction rope 5 creates a gap between the two adjacent support plates 3 for vertical placement of the board. The board is then secured between the two adjacent support plates 3 through the slot 4. After the board is inserted into the slot 4, a gap will naturally form between the boards. On the one hand, this is conducive to ventilation and moisture prevention of the board. On the other hand, it can prevent the negative pressure adsorption phenomenon caused by the tight adhesion of the boards. This makes it easier for workers to quickly align and apply force during placement and removal, and to independently pick up and put down a single board, making the operation smoother and less labor-intensive.

[0035] When using, such as Figure 1 As shown, in the initial state, all sliders 2 slide naturally down the slide rail 1 under their own gravity, with adjacent sliders 2 overlapping each other, so that the support plate 3 is in the lowest position of the slide rail 1 (the top slider 2 and support plate 3 are in the lowest position). Then, the worker loads the same batch of boards between the top two support plates 3, so that the support plate 3 stands upright in the slot 4 between the two support plates 3 and contacts the buffer pad in the slot 4. The purpose is to achieve work without climbing. The initial low position makes the support plate 3 at a comfortable operating height for the human body. The worker can complete the stacking of boards by standing, without climbing, completely avoiding the safety hazard of falling from height, reducing labor intensity, and eliminating the need for additional climbing tools, thus greatly improving stacking efficiency. It should be noted that, due to the large quantity and uniform specifications of the boards in the same batch, if the boards are horizontal... Stacking materials requires a large area and has limited layers. Since the materials are laid horizontally, too many sliders 2 and support plates 3 are needed. When all sliders 2 descend, the overall stack height increases, directly causing the device to fail in its initial low-position state. Excessive slider stacking also exceeds the operator's reach, requiring them to tiptoe or use auxiliary tools to place the materials, increasing labor intensity and reducing stacking efficiency. However, vertical placement eliminates the need for additional sliders 2 and support plates 3 at the same height. The initial stack height is low, allowing operators to work while standing, reducing labor intensity and increasing efficiency. Vertical placement avoids the problems of requiring too many sliders 2 and support plates 3 for horizontal placement, which leads to initial low-position failure and operational inconvenience.

[0036] With the workman in a low position, the same batch of boards are vertically inserted into the slots 4 of the support plate 3. The slots 4 on the upper and lower surfaces of the support plate 3, as well as the protective pads 8 inside the slots 4, provide a limit for the boards, ensuring that the boards remain vertical and do not tip over or slip. With the boards placed vertically, their own weight is transferred vertically along the board surface, eliminating surface pressure from upper boards onto lower boards and avoiding bending, indentation, warping, and deformation damage caused by horizontal stacking. After the boards are inserted into the slots 4, gaps will naturally form between the boards. On the one hand, this facilitates ventilation and moisture prevention; on the other hand, it prevents negative pressure adsorption caused by the boards being tightly fitted together. This allows the workman to quickly align and apply force during placement and removal, enabling independent handling of individual boards and making the operation smoother and less strenuous.

[0037] like Figure 2 and Figure 4 As shown, the support plate 3 allows the boards to be placed vertically without occupying a large amount of horizontal space, enabling dense and orderly arrangement of boards of the same batch, greatly improving the utilization rate of the space above the storage room. Several of these devices can be installed and arranged in the storage room.

[0038] Then, a conventional industrial winch 9, with its own braking and self-locking structure, is used. Under rated load and static conditions, it can pull the slider 2 to a specified height and remain suspended at a fixed height for a long period after stopping, without falling back or sliding down on its own. When the winch 9 starts, the uppermost slider 2 is guided and pulled upward along the slide rail 1 by the stationary pulley 10. As the uppermost slider 2 rises, the traction rope 5 between adjacent sliders 2 is gradually tightened. When the traction rope 5 is fully tightened, its length limits the distance between two adjacent load-bearing plates 3, making it exactly equal to the height of the plate, thus forming a stable plate placement gap. It should be noted that... The spacing between two adjacent support plates 3 can be determined by the length of the traction rope 5, or by changing the traction rope 5 to a different length. The length of the traction rope 5 is customized according to the height of the same batch of boards to fit the length of the boards. Then, the workers continue to load the next board into the slot 4 of the lower support plate 3, and so on, lifting and loading the boards one by one. There is no need for manual measurement or adjustment of the layer spacing. The gap height is precisely matched to the boards, avoiding the waste of space due to excessive spacing or the inability to load the boards due to insufficient spacing. All boards are loaded at a low position, with no climbing operations throughout the process, resulting in low labor intensity and high safety.

[0039] Next, as Figure 2As shown, once all the boards are loaded, the entire structure is lifted to form a ground passage. After all the boards are inserted into the slots 4, the winch 9 continues to pull all the sliders 2 and the support plates 3 upwards along the slide rails 1, creating a sufficiently high passageway between the bottom support plate 3 and the ground. This solves the problem of traditional fixed-height shelves occupying passageways and affecting personnel access. After stacking, the entire device is positioned at a high level, freeing up ground space and not affecting staff access or other operations. It fully utilizes the upper space of the storage room, achieving dual-layer utilization of upper storage and lower passage, resulting in a high space utilization rate.

[0040] When the device does not require stacking of plates, such as Figure 1 and Figure 3 As shown, first lower the slider 2 and the bearing plate 3 to the low position, then remove the connecting piece 302 between the bearing plates 3, so that the bearing plate 3 can naturally hang down and retract by its own weight around the rotation axis of the fixed bracket 7. During this process, the winch 9 is needed to lift the disassembled bearing plate 3, and then disassemble the bearing plates 3 layer by layer. After all the bearing plates 3 are retracted, the space freed up can be flexibly stacked with other materials, further improving the comprehensive utilization rate of the storage space.
