Description

Technical Field

[0001] This invention relates to the field of ship plate layering and stacking technology, specifically to an intelligent layering, stacking, and straightening device for rolled ship plates. Background Technology

[0002] Ship plates are a core material in the shipbuilding industry and marine engineering equipment manufacturing. The quality of their post-rolling processing directly determines the mechanical properties, corrosion resistance, and safety of subsequent use. Stacking is a key process in the post-rolling storage and transportation of ship plates, requiring the plates to be stacked neatly. However, the current ship plate stacking operation mode has the following drawbacks: The existing ship plate stacking area occupies a large area, and the distance between the stacking area and the loading area is far, resulting in a significant increase in the travel of the lifting equipment during stacking and loading. This not only prolongs the single transfer time but also reduces overall operational efficiency. During stacking, to distribute the downward pressure on the ship plates and prevent deformation and rust at the joints, pads need to be manually laid between the ship plate layers. When loading the ship plates, the original pads must be removed one by one, and then new pads must be laid in the truck bed. The entire process relies on repetitive manual operations, which are labor-intensive, tedious, and consume a lot of time. In addition, manual laying is prone to misalignment of the pads, affecting the stability of the ship plate support. The storage environment for ship plates is prone to high humidity, and the existing stacking method lacks effective dehumidification measures between the ship plate layers. Moisture easily accumulates in the gaps between the ship plate joints, accelerating corrosion and damaging the mechanical properties and surface quality of the ship plates. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an intelligent layered stacking and straightening device for rolled ship plates, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A smart layered stacking and straightening device for rolled ship plates includes a central turnover component, a stacking frame, a laying position adjustment component, a pad laying box, and a pad assembly. The central turnover component includes multiple horizontal rails, with a loading area and an unloading trough between each pair of horizontal rails. An infeed roller frame is installed above the loading area. A sliding hanger is slidably mounted on the top of each horizontal rail, and multiple sets of first longitudinal guide rails are vertically slidably mounted inside the sliding hanger. The stacking frame is symmetrically arranged on both sides of the unloading trough. Multiple layers of pallets are spaced apart within the stacking frame, and a second longitudinal guide rail is installed on the bottom surface of each layer of pallets. Air supply ducts are provided on the side walls of the stacking frame. The laying position adjustment component is located outside each set of stacking frames and includes multiple sets of vertically lifting third longitudinal guide rails and a lifting component mounted on the multiple sets of third longitudinal guide rails. The bottom of the lifting component is equipped with… The system includes multiple sets of padding boxes; padding assemblies for longitudinally stacking the padding assemblies on the surface of the ship plate; each padding assembly includes a head padding block, a tail padding block, and at least one middle padding block disposed between the two, the bottom surfaces of the head padding block and the tail padding block are provided with magnetic plates, the head padding block, the middle padding block and the tail padding block are connected in series through multiple sets of series pipes, and each has an exhaust hole on its side, the tail padding block has a built-in air guiding docking component; it also includes a magnetic transfer component, which is hung on the bottom of the first longitudinal guide rail to magnetically transfer the ship plate; when the first longitudinal guide rail is docked with the second longitudinal guide rail, the magnetic transfer component moves along the second longitudinal guide rail; when the third longitudinal guide rail is docked with the second longitudinal guide rail, the hoisting component drives the padding box to move along the second longitudinal guide rail to longitudinally lay the padding assembly on the surface of the ship plate.

[0005] This invention provides an intelligent layering, stacking, and straightening device for rolled ship plates. Compared with existing technologies, it has the following advantages: This invention proposes a symmetrical layout of the palletizing racks on both sides, with an unloading trough between the two racks. The central turnover component and magnetic transfer component enable continuous palletizing and unloading of ship plates, improving production continuity. Simultaneously, the palletizing racks employ a layered pallet design, combined with precise positioning by the magnetic transfer component, ensuring neat and orderly layered pallet stacking, avoiding misalignment, and improving palletizing quality and efficiency. Each pallet layer has a second longitudinal guide rail on the ground, which can be aligned with the first longitudinal guide rail of the central turnover component. The magnetic transfer component can move across the guide rails, achieving automated transfer of ship plates from the feed roller rack to the palletizing rack. The present invention proposes that the third longitudinal guide rail of the laying position adjustment component is connected to the second longitudinal guide rail, and the hoisting component drives the pad block laying box to move across the guide rail, thereby realizing the automated laying of the pad block component; This invention proposes a pad assembly connected as a single unit via series pipes, which can be quickly unfolded to fit the width of the ship's deck, eliminating the need for manual placement of individual pads, reducing labor intensity, and ensuring uniform spacing of the pads. The head, middle, and tail pads of the assembly have vent holes, and the air guide connection component connects the upper and lower pads with the air supply pipes, allowing hot air to directly reach the gaps in the ship's deck, efficiently removing moisture and preventing the deck from becoming damp and corroding. Magnetic plates on the head and tail pads ensure the pads are firmly attached and fixed, preventing displacement of the assembly. The three-state conversion of the pad assembly (temporary storage, transfer, and unfolded use) saves storage space and quickly adapts to palletizing and transport needs. The pad assembly can be reused throughout the entire process of palletizing, storage, and loading, and can be transferred along with the ship's deck during loading, eliminating the need for separate manual placement.

[0009] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0010] Traditional ship plate stacking after rolling has problems such as process interruption, low efficiency of padding, uneven ventilation and dehumidification between layers, and the need to repeatedly lay padding during loading.

[0011] As the technical concept and principle of this invention, such as Figures 1-21 As shown, the present invention provides an intelligent layered stacking and straightening device for rolled ship plates, comprising: an infeed roller frame 110, an unloading trough 120, a central turnover component 200, a stacking frame 300, a laying position adjustment component 400, a temporary storage component 500, a padding block laying box 600, and a padding block component 700. The purpose is to construct an automated stacking and straightening device for stacking, padding block management, ventilation and dehumidification, and unloading.

[0012] Its workflow is as follows: Figures 1-2 , Figure 19 As shown, the layered palletizing and organizing device proposed in this invention is symmetrically arranged with the unloading trough 120 as the center, and a set of palletizing racks 300 are set on each side, as follows. Figure 20 As shown, a feed roller frame 110 is installed above the feeding area in the region between the two sets of palletizing racks 300; as Figure 3As shown, the central turnover component 200, spanning this area, uses its translational hanger and magnetic transfer component 250 to achieve the adsorption, transfer, and precise stacking of ship plates from the infeed roller frame 110 to each layer of pallets 320 on the stacking frame 300, and to transfer the stacked ship plates (along with the pad assembly 700) to the trucks in the unloading trough 120; as Figure 6 , Figure 7 As shown, a laying position adjustment component 400 is correspondingly installed on the outside of the palletizing rack 300. This component, via a liftable third longitudinal guide rail 421 and a lifting component 430, drives the pad laying box 600 to extract the pad assembly 700 in its first state (tightly fitted) from the temporary storage component 500 on the ground and transfer it into the palletizing rack 300; as shown... Figure 8 As shown, the pad block laying box 600 unfolds the pad block assembly 700 from the second state (temporarily stored in the box) to the third state (longitudinally laid on the pallet 320 or the surface of the ship plate) through the push-out action, and is fixed by the magnetic plates of the head and tail pad blocks; during stacking, the downward pressure of the upper ship plate triggers the air guide docking component 760, so that the lower docking pipe 762 of the tail pad block 730 is automatically inserted into the upper docking pipe 761 or the diversion air pipe 340 of the lower tail pad block, thereby discharging the hot air provided by the air supply pipe into the gap between the ship plates through the series air guide channels from the exhaust holes 750 of each pad block, realizing continuous and automated stacking, straightening, dehumidification and unloading operations.

[0013] In one embodiment of the present invention, the proposed central turnover component 200 aims to integrate the discrete feeding, storage and loading processes into an efficient and coherent whole process, improve the efficiency of ship plate stacking and unloading operations and space utilization, and ensure stable transfer process and accurate positioning.

[0014] In specific implementation, such as Figure 3 , Figure 4 As shown, it includes two sets of horizontal ground rails 260, a translational lifting frame (including a first traveling frame 210, a vertical guide rail frame 220, a main lifting beam 230 and a first longitudinal guide rail 240) and a magnetic transfer component 250 (including a second traveling frame 251, a lifting cylinder 252, a lifting support frame 253 and an electromagnetic suction plate 254).

[0015] Specifically, two sets of horizontal ground rails 260 are fixed parallel to the ground, with a loading area and an unloading trough 120 between them. An infeed roller frame 110 is installed above the loading area. A translational crane (rollingly connected via a first traveling frame 210) is slidably mounted on the top of the horizontal ground rails 260. It should be noted that the horizontal ground rails 260 provide a horizontal track for the translational crane, allowing it to reciprocate between the loading area and the unloading trough 120 along the horizontal ground rails 260. This achieves overall lateral displacement of the translational crane, covering the entire work area from loading and stacking of ship plates to unloading, thus ensuring continuous efficiency in ship plate transfer.

[0016] Furthermore, the translational lifting frame includes a first traveling frame 210, a vertical guide rail frame 220, a main lifting beam 230, and a first longitudinal guide rail 240. It should be noted that the translational lifting frame achieves lateral movement through the first traveling frame 210, provides vertical guidance through the vertical guide rail frame 220, allows for height adjustment through the main lifting beam 230, and provides longitudinal guidance through the first longitudinal guide rail 240. Its purpose is to serve as the load-bearing and moving base for the magnetic transfer component 250, completing the automated transfer of ship plates from the loading area to the multi-layer stacking rack.

[0017] In specific implementation, the first traveling frame 210 is rolled on the top of the horizontal ground rail 260 to serve as the moving base of the translational hanger. The top of the two sets of first traveling frames 210 is fixedly installed with vertical guide rail frames 220, which cooperate with the horizontal ground rail 260 through rollers or sliders and slide laterally along the rail under the action of the driving device.

[0018] Furthermore, the vertical guide frame 220 is fixedly installed on the top of the two sets of first traveling frames 210 to form a portal or rectangular rigid frame. The purpose is to transmit the horizontal movement of the first traveling frame 210 to the upper part and provide a constraint track for the vertical movement of the main lifting beam 230, supporting the main lifting beam 230 and providing stable guidance.

[0019] Furthermore, two sets of main lifting beams 230 are symmetrically arranged, extending laterally and sliding vertically on the guide rails inside the vertical guide rail frame 220. At the same time, the bottoms of the two sets of main lifting beams 230 are connected to multiple sets of first longitudinal guide rails 240. The multiple sets of first longitudinal guide rails 240 are arranged in parallel and their extension direction is perpendicular to the horizontal ground rail 260. The purpose is to guide the magnetic transfer component 250 to move longitudinally, realize the smooth transfer of the ship plate from the translational lifting frame to the pallet 320 of the stacking frame 300, and form a continuous track system with the second longitudinal guide rail 330 on the stacking frame, so as to ensure the automation and connection of the transfer process.

[0020] In one embodiment of the present invention, such as Figure 4 As shown, the magnetic transfer component 250 includes a second traveling frame 251, a lifting cylinder 252, a lifting support frame 253, and an electromagnetic chuck 254. Specifically, the second traveling frame 251 is mounted on each set of first longitudinal guide rails 240, and the lifting cylinders 252 are symmetrically arranged at its bottom. The bottoms of multiple sets of lifting cylinders 252 are connected to the lifting support frame 253, and the electromagnetic chuck 254 is installed at the bottom of the lifting support frame 253. It can be understood that the second traveling frame 251 serves as the moving base of the magnetic transfer component 250, enabling it to move precisely along the first longitudinal guide rails 240 under the action of the drive device, completing the automated and continuous transfer of ship plates from the turnover area to the storage area, reducing manual intervention in the transfer process.

[0021] Based on the above technical concept, it should be noted that: the translational lifting frame moves precisely along the horizontal ground rail 260, the first longitudinal guide rail 240 and the second longitudinal guide rail 330 are precisely connected, and the magnetic transfer component 250 travels along the guide rails, realizing the precise positioning and transfer of the ship plate from the feed roller frame 110 to the pallet 320, avoiding stacking misalignment and improving stacking quality. The second traveling frame 251 can smoothly switch between the first longitudinal guide rail 240 and the second longitudinal guide rail 330, realizing continuous cross-regional transfer of ship plates without intermediate manual intervention, greatly improving transfer efficiency; the guide rail connection structure is simple and reliable, reducing transfer failures. The electromagnetic chuck 254 provides strong magnetic attraction, which can stably attract ship plates, and together with the rigid support of the lifting frame 253, it prevents the ship plates from shaking or falling off during transfer, ensuring production safety; the electromagnetic chuck 254 can be released when power is off, making operation convenient. The main lifting beam 230 slides vertically along the vertical guide frame 220, and the height of the magnetic transfer component 250 can be flexibly adjusted to adapt to the stacking requirements of pallets 320 with different layers; the lifting cylinder 252 drives the lifting frame 253 to lift and lower, so as to achieve precise placement of the ship plate and avoid collision with the pad assembly 700.

[0022] In one embodiment of the present invention, such as Figures 1-2 , Figure 5 As shown, the proposed palletizing rack 300 is symmetrically arranged on both sides of the unloading trough 120, including a main air pipe 310, a multi-layer pallet 320, a second longitudinal guide rail 330, and a diversion air pipe 340.

[0023] In practice, the stacking rack 300 is provided with multiple layers of pallets 320 at intervals, and the space between adjacent pallets 320 is formed for storing ship plates. Each group of ship plates is separated by a pad assembly 700.

[0024] Furthermore, the pallet 320 is a horizontal load-bearing structure, and its bottom surface is equipped with a second longitudinal guide rail 330. The extension direction of the second longitudinal guide rail 330 is perpendicular to the horizontal ground rail 260, and it can be precisely connected with the first longitudinal guide rail 240 of the central turnover component 200. Figure 21 As shown, each pallet 320 has a set of branch air pipes 340 on the outer wall of the pallet rack 300. All branch air pipes 340 are connected in parallel to the main air pipe 310 located on the outer side of the pallet rack 300. The main air pipe 310 is used to access external hot air and deliver the hot air to the pad assembly 700 of the corresponding layer through the branch air pipes 340 of each layer.

[0025] Based on the above technical concept, it should be noted that: the multi-layer pallet 320 proposed in this invention provides a basis for the orderly stacking of ship plates in layers, and uses the pad block assembly 700 to maintain the gap between layers. After the second longitudinal guide rail 330 at the bottom of the pallet 320 is connected to the first longitudinal guide rail 240, it provides a precise track for the magnetic transfer component 250 to enter the inside of the pallet rack, realizing the automated storage and retrieval of ship plates.

[0026] During palletizing and storage, to achieve efficient dehumidification, this invention proposes that the air supply duct installed on the side wall of the palletizing rack 300 and the air guiding system of the pad assembly 700 work together. Specifically, the main air pipe 310 located on the outside of the palletizing rack 300 is connected in parallel with multiple branch air pipes 340. Each branch air pipe 340 corresponds to and is installed on the outer side wall of a layer pallet 320. When the pad assembly 700 is laid on the pallet or ship plate and is in the third state (longitudinal unfolding), the lower connecting pipe 762 in the air guiding docking component 760 of the tail pad 730 located at the end of the layer automatically moves downward under the downward pressure of the ship plate and accurately inserts into the reserved interface of the corresponding layer branch air pipe 340, completing the automatic air path docking.

[0027] Thus, the hot air entering from the main air duct 310 is diverted to the branch air ducts 340 of each layer, and then introduced into the tail pad 730 through the docking lower connecting pipe 762. At this time, the hot air is delivered to the head pad 710 and each middle pad 720 through its internal air guide channel and series pipe fittings 740. Finally, the hot air is evenly blown laterally into the gaps between the ship plates from the exhaust holes 750 on the sides of all pads. This creates a layered, independent, automatically dockable ventilation and dehumidification system, ensuring that the hot air can cover the surface of each layer of ship plates in the entire stacking area without dead angles, effectively dispersing moisture, preventing localized corrosion of the ship plates during storage, and requiring no manual intervention throughout the entire process, perfectly synchronized with the automated stacking process.

[0028] In one embodiment of the present invention, such as Figures 1-2 , Figure 6 As shown, the proposed laying position adjustment component 400 includes a gantry frame 410, a laying lifting column 420, multiple sets of third longitudinal guide rails 421, and a hoisting component 430.

[0029] In practice, the laying position adjustment component 400 is set on the outside of each stacking rack 300, and the laying lifting column 420 is vertically slidably installed inside the gantry frame 410. Multiple sets of vertically extending third longitudinal guide rails 421 are provided on the side of the laying lifting column 420 at intervals.

[0030] Furthermore, such as Figure 7 As shown, the hoisting component 430 includes multiple sets of third traveling frames 431, laying lifting cylinders 432, lifting rods 433, and lifting blocks 434. The third traveling frames 431 of the hoisting component 430 are respectively hung on the bottom of the corresponding third longitudinal guide rails 421. The bottom of the third traveling frame 431 is provided with laying lifting cylinders 432. The bottom of multiple sets of laying lifting cylinders 432 are connected to a horizontally arranged lifting rod 433. The bottom surface of the lifting rod 433 is provided with multiple sets of lifting blocks 434 for connecting and hoisting the pad laying box 600.

[0031] Based on the above technical concept, it should be noted that: the laying lifting column 420 proposed in this invention can be raised and lowered along the gantry frame 410, thereby driving the third longitudinal guide rail 421 and the entire hoisting component 430 to be adjusted to a position that matches the pallet 320 of different layer heights of the stacking frame 300, thus adapting to the pad laying requirements of pallet 320 with different layers and being compatible with stacking frames 300 of different specifications; when the third longitudinal guide rail 421 is aligned and connected with the second longitudinal guide rail 330 on the stacking frame 300, the third traveling frame 431 can carry the pad laying box 600 and move it smoothly into the inside of the stacking frame along the guide rail, thereby providing an automated conveying platform for the pad laying box 600 that can adjust its height in the vertical direction and move across areas in the horizontal direction, realizing the automatic and accurate transfer and laying of the pad assembly 700 from the ground temporary storage position to any designated layer of pallet 320 or ship plate surface in the stacking frame.

[0032] In one embodiment of the present invention, such as Figures 1-2 , Figure 20 As shown, the proposed temporary storage component 500 includes a temporary storage box 510, a push plate 520, and a third drive rod 521. In a specific implementation, the temporary storage box 510 is placed on the ground, and a set of temporary storage component storage boxes 510 is correspondingly provided on one side of the bottom of each set of pad block laying boxes 600. The top and both ends of the temporary storage box 510 are open structures, and the push plate 520 is embedded in the end away from the pad block laying box 600. The outer side of the push plate 520 is connected to the drive end of the third drive rod 521.

[0033] Based on the above technical concept, it should be noted that the temporary storage box 510 proposed in this invention utilizes its three-sided open structure to facilitate the longitudinal arrangement and stacking of multiple sets of pad block assemblies 700 in the first state (i.e., the head pad block 710, the middle pad block 720, and the tail pad block 730 are tightly fitted) by manual labor or equipment. This achieves centralized and orderly temporary storage of the pad block assemblies, saving floor space. In practical applications, when the pad block laying box 600 needs to be filled, the third drive rod 521 drives the push plate 520 to move towards the pad block laying box 600, thereby smoothly pushing out the foremost set of pad block assemblies 700 in the temporary storage box 510 and laterally transferring them into the docking pad block laying box 600, completing the automated feeding from the "first state" to the "second state," and providing a continuous and efficient material supply for subsequent automated pad block laying operations.

[0034] In one embodiment of the present invention, such as Figures 6-7 As shown, the proposed pad block laying box 600 is connected to the lifting rod 433 of the lifting component 430 via a lifting block 434 at its top, for receiving, temporarily storing, and laying the pad block assembly 700. Figure 8 As shown, it includes a side plate 610, a rear baffle 611, a feed guide plate 612, a top plate 620, a bottom plate 630, a clearance groove 631, a flap 640, a contact plate 641, and a screw seat 642.

[0035] In practice, the bottom end of the side plate 610 is vertically connected to the bottom plate 630 and the top end is vertically connected to the top plate 620, thus forming a stable U-shaped main frame; the top plate 620 is arranged parallel above the bottom plate 630, and its end away from the side plate 610 is rotatably connected to the flap 640 through a hinge.

[0036] Furthermore, a rear baffle 611 is fixedly provided at the rear end of the inner wall of the side plate 610 to limit the pad assembly 700 from the rear; such as Figure 9 As shown, the surface of the base plate 630 is provided with an L-shaped clearance groove 631 to accommodate the lower connecting pipe 762 extending outward from the bottom of the tail pad block 730, so as to avoid structural interference.

[0037] Furthermore, the feed guide plate 612 is fixedly installed at the front end of the side plate 610 of the pad laying box 600. Specifically, it is located at the end of the pad laying box 600 facing the inside of the stacking frame 300 during the laying operation, and is used to push out the pad assembly 700. The inner wall of the flip plate 640 is flush with the screw seat 642, and the inner side of the screw seat is threaded with an abutment plate 641 that can move back and forth. The purpose is to drive the abutment plate 641 to push the pad assembly 700 through the screw seat 642. With the guiding effect of the feed guide plate 612 and the extension of the flip plate 640, the head pad 710 is accurately adsorbed and positioned at the designated position on the tray 320. Meanwhile, the front end of the flap 640 extends outward beyond the boundary of the top plate 620, while the front end of the side plate 610 is provided with an inclined feed guide 612. When the flap 640 is rotated downward to close, its extended part and the feed guide 612 together form a double-sided constrained guide channel.

[0038] Based on the above technical concept, it can be understood that the side plate 610, top plate 620, bottom plate 630, and flip plate 640 of the pad laying box 600 form a closed temporary storage space. During operation, the flip plate 640 rotates upward to open and docks with the temporary storage box 510 to receive the pad assembly 700. After receiving, the flip plate 640 closes, and the side plate 610 and the flip plate 640 constrain the pad from both sides to prevent displacement during transfer. When laying is required, the pad laying box 600 is transported above the pallet 320 and aligned in position. The screw seat 642 drives the contact plate 641 to move forward, pushing out the pad assembly 700 as a whole.

[0039] It should be noted that during this process, the head pad 710 is first pushed out and passes through the guide channel formed by the feed guide plate 612 and the extension of the flip plate 640. The first magnetic plate 712 at its bottom is precisely attracted and fixed at the preset starting position of the pallet 320. Subsequently, the pad laying box 600 moves outward under the action of the hoisting component 430, and the series pipe 740 is gradually straightened, thereby pulling the subsequent middle pad 720 and tail pad 730 to unfold and lay flat on the surface of the pallet 320 in sequence. The L-shaped clearance groove 631 ensures that the lower connecting pipe 762 passes smoothly without collision.

[0040] Thus, the pad assembly 700 is fully automated and precisely positioned and laid from its compact temporary storage state to its working deployment state, and the air passage components (lower connecting pipe 762) and magnetic adsorption components (first magnetic plate 712) of the pad assembly 700 are not damaged and are accurately positioned during the transfer and laying process.

[0041] In one embodiment of the present invention, such as Figure 1 , Figure 11 As shown, the proposed pad assembly 700 includes a head pad 710, multiple middle pads 720, a tail pad 730, a series pipe 740, and an air guide docking component 760 installed in the tail pad. Each of the aforementioned pads has an exhaust hole 750 on its side.

[0042] In practical implementation, the pad assembly 700 connects the head pad 710, middle pad 720, and tail pad 730 sequentially into a single unit via multiple sets of series pipe fittings 740. For example... Figure 13 As shown, the series pipe fitting 740 includes a main pipe body 741, and both ends of the main pipe body 741 are provided with double-ended pipes 742 arranged in an I-shape. The two ends of the double-ended pipes 742 are connected to each pad block through a rotating joint 743.

[0043] Based on the above technical concept, it can be understood that the main body 741 and the double-ended pipe 742 of the series pipe fitting 740 are in an I-shape, and with the rotating joint 743, the series pipe fitting 740 can rotate flexibly, so that the pad assembly 700 can not only fit together for compact temporary storage, but also be quickly unfolded to adapt to different widths of ship plates, improving the flexibility of use; at the same time, the series pipe fitting 740 connects the air guide channels of the head pad 710, the middle pad 720, and the tail pad 730, so that hot air can be evenly discharged through the exhaust hole 750 of the entire pad assembly 700, ensuring ventilation and dehumidification of the gap between the ship plates and avoiding localized dampness; by connecting the pads into a whole through multiple sets of series pipe fittings 740, it is possible to prevent individual pads from falling or shifting during stacking and transportation, ensuring the neatness of stacking; the symmetrical layout of the series pipe fittings 740 allows hot air to be discharged from both sides of the pad assembly 700 through the exhaust hole 750, expanding the ventilation coverage, accelerating the moisture dissipation speed, and improving the dehumidification efficiency.

[0044] Furthermore, such as Figure 12 , 21 As shown, the head pad block 710 of the present invention has an L-shaped first air guide channel 713 symmetrically opened inside, and a first assembly notch 711 is opened on the top surface near the middle pad block. Rotary joints 743 are symmetrically installed in the notch. The top end of the first air guide channel 713 is connected to the rotary joint 743, and the side is connected to multiple sets of exhaust holes 750. The bottom surface of the head pad block 710 is provided with a first magnetic plate 712.

[0045] Based on the above technical concept, it can be understood that the first magnetic plate 712 on the bottom surface of the head pad 710 can be adsorbed and fixed on the support plate 320 or the surface of the ship plate, ensuring accurate head positioning after the pad assembly 700 is unfolded, avoiding displacement during stacking or ventilation, and ensuring uniform separation of the ship plates; the L-shaped first air guide channel 713 allows hot air to be discharged laterally from multiple exhaust holes 750, covering the ship plate areas on both sides of the head pad 710, with a wide and uniform ventilation range; at the same time, the first air guide channel 713 is precisely connected to the rotary joint 743 to ensure smooth airflow and no hot air leakage; the rotary joint 743 in the first assembly notch 711 is precisely matched with the series pipe 740, facilitating the assembly and unfolding of the pad assembly 700, and achieving dual connection of airflow and structure without complicated operations; the structural design of the assembly notch avoids the rotary joint 743 interfering with the temporary storage of the pad.

[0046] Furthermore, such as Figure 14 , Figure 10 As shown, the intermediate pad block 720 of the present invention has symmetrically formed U-shaped second air guide channels 722 inside, and second assembly notches 721 are formed on both sides of the top surface. Rotary joints 743 are symmetrically installed in the notches. The top of the second air guide channel 722 is connected to the two sets of rotary joints 743, and the side is connected to the exhaust port 750.

[0047] Based on the above technical concept, it can be understood that the U-shaped second air guide channel 722 connects the exhaust holes 750 on both sides, allowing hot air to be discharged simultaneously into the gaps between the ship plates on both sides of the middle pad block 720, providing comprehensive ventilation coverage, preventing localized moisture absorption of the ship plates, and improving dehumidification uniformity. Simultaneously, the rotating joints 743 within the second assembly notches 721 on both sides of the middle pad block 720 cooperate with the series pipes 740, allowing the middle pad block 720 to flexibly unfold or fit with the assembly without affecting the overall structural compactness. The rotating connection method reduces component wear and improves durability. The number of middle pad blocks 720 can be increased or decreased according to the width of the ship plates, flexibly adapting to the separation requirements of different specifications of ship plates without replacing the entire pad block assembly 700, reducing operating costs. Furthermore, multiple sets of middle pad blocks 720 connected in series form a stable separation structure, preventing ship plate compression deformation. The solid structural design of the middle pad block 720 ensures sufficient strength to withstand the pressure of stacked ship plates, preventing deformation under pressure, ensuring stable gaps between ship plates, and guaranteeing ventilation effect and stacking neatness.

[0048] Furthermore, such as Figure 15 As shown, the tail pad block 730 proposed in this invention has a third assembly notch 731 on the top surface near the middle pad block, and a rotating joint 743 is symmetrically installed in the third assembly notch 731; the bottom surface of the tail pad block 730 is provided with a second magnetic plate 732, and its interior is divided into a solid area and a cavity area: a third air guide channel 733 is provided in the solid area, the top of which is connected to the rotating joint 743 in the third assembly notch 731, and the side is connected to the exhaust hole 750; an air guide docking component 760 is installed in the cavity area.

[0049] Based on the above technical concept, it can be understood that the air guiding docking component 760 built into the stern pad 730 can automatically dock with the upper pad or the diversion air pipe 340 when the ship plate is pressed down, without manual operation, to achieve rapid air path connection and improve the continuity of stacking and ventilation; at the same time, the second magnetic plate 732 on its bottom surface is adsorbed and fixed on the ship plate or the support plate 320, ensuring that the stern pad 730 is accurately positioned and cooperates with the head pad 710 to form a stable end positioning, avoiding the overall displacement of the pad assembly 700 and ensuring uniform separation of the ship plate; in addition, the third air guiding channel 733 in the solid area is precisely connected with the exhaust hole 750 and the rotating joint 743 to ensure unobstructed flow of hot air; the air guiding docking component 760 is independently arranged in the cavity area to avoid interference with the air guiding channel and ensure the air path sealing and unobstructed flow.

[0050] Furthermore, such as Figure 15 , Figure 16 As shown, the air guiding docking component 760 proposed in this invention includes an upper docking pipe 761, a lower docking pipe 762, a contact post 763, a diagonal connecting rod 764, and a slide block 765.

[0051] The upper connecting pipe 761 is fixed to the top of the tail end of the tail pad 730. The top of the upper connecting pipe 761 extends outward from the tail pad 730. The cavity area is provided with a vertically arranged slide 765. A spring 7651 is embedded inside the slide 765. A slider 7631 is slidably embedded in the side of the slide 765. The slider 7631 is placed on the top of the spring 7651. The slider 7631 is located on one side of the bottom end of the contact post 763. The contact post 763 slides vertically through the top surface of the tail pad 730.

[0052] like Figure 17As shown, a diagonal connecting rod 764 is provided on the other side of the bottom end of the contact post 763. The bottom end of the diagonal connecting rod 764 is connected to the lower connecting pipe 762. The lower connecting pipe 762 is located at the tail end of the tail pad block 730. The lower connecting pipe 762 is placed directly below the upper connecting pipe 761. The bottom end of the lower connecting pipe 762 extends outward from the tail pad block 730. An air guide cavity 7641 is opened inside the diagonal connecting rod. The air guide cavity 7641 is connected to the upper connecting pipe 761 through the first hose 7642. The air guide cavity 7641 is connected to the third air guide channel 733 through the second hose 7643. The clearance groove 631 is used to avoid the outward extension of the lower connecting pipe 762. The top plate 620 is located on the top of the upper connecting pipe 761 and the contact post 763.

[0053] Based on the above technical concept, it can be understood that by forming a stable linkage structure with the contact post 763, the diagonal connecting rod 764, the slide 765 and the spring 7651, the docking parts can be automatically inserted and removed when the ship plate is placed and removed. The operation is reliable and the failure rate is low. The guiding effect of the slide 765 ensures that the lower docking pipe 762 is raised and lowered vertically, improving the docking accuracy.

[0054] In one embodiment of the present invention, the proposed pad assembly 700 has the following three operating states: First state: The head pad 710, middle pad 720 and tail pad 730 are tightly fitted together by the rotation of the series pipe 740 and are temporarily stored in the temporary storage assembly 500 in a compact arrangement.

[0055] Second state: Each pad remains in contact and is temporarily stored in the pad laying box 600, with the connecting pipe 762 below it being accommodated in the clearance groove 631 at the bottom of the box.

[0056] In the third state: each pad is laid out longitudinally on the surface of the ship plate. The head pad 710 and the tail pad 730 are fixed to the ship plate by magnetic plates on their bottom surfaces (the head pad is fixed to the bearing surface by the first magnetic plate on its bottom, and the tail pad is fixed to the bearing surface by the second magnetic plate on its bottom). When the contact post 763 is driven by the downward pressure of the ship plate, it moves the lower connecting pipe 762 downward through the diagonal connecting rod 764, realizing automatic insertion with the diversion air pipe 340 or the connecting pipe 761 on the upper pad, without the need for manual alignment, which greatly improves docking efficiency and stacking continuity. At the same time, the air guide chamber 7641 diverts hot air to the first hose 7642 (connected to the upper connecting pipe 761) and the second hose 7643 (connected to the third air guide channel 733), so that hot air can be supplied to the exhaust of the pad in this layer and the air passage of the upper pad at the same time, realizing synchronous dehumidification of the upper and lower ship plates and improving the uniformity of dehumidification.

[0057] Working principle and usage process of this invention: S1. Ship Plate Lifting and Loading: Rolled ship plates are output by the feed roller frame 110. The middle turnover component 200 is activated, and its translational lifting frame moves along the horizontal ground rail 260 to above the feed roller frame. The main lifting beam 230 descends so that the electromagnetic suction plate 254 of the magnetic transfer component 250 contacts and attracts the ship plate. Then it is lifted and moved laterally to the preparatory position between the two sets of stacking frames 300.

[0058] S2. Automatic laying of bottom layer blocks: The laying lifting column 420 of the laying position adjustment component 400 descends, causing the block laying box 600 to align with the temporary storage box 510. For example... Figure 18 As shown, the pusher plate 520 inside the temporary storage box 510 pushes a set of pad assembly 700 in the first state (tightly fitted) into the pad laying box 600, transforming it into the second state. The hoisting component 430 lifts the pad laying box and moves it along the third longitudinal guide rail 421 and the second longitudinal guide rail 330 via the third traveling frame 431, precisely positioning the pad laying box above the target tray 320. The contact plate 641 of the pad laying box 600 pushes out the pads. The head pad 710 is first magnetically fixed to the tray. As the laying box moves outward, the series pipe 740 is straightened, and the middle pad 720 and the tail pad 730 are sequentially pulled out and laid flat on the surface of the tray, completing the third state of deployment.

[0059] S3. Layered Stacking of Ship Plates and Automatic Air Path Connection: The magnetic transfer component 250 carries the ship plates and enters the stacking frame along the first longitudinal guide rail 240 and the second longitudinal guide rail 330 via the second traveling frame 251, precisely placing the ship plates onto the pre-laid pad assembly 700. The ship plates press down on the contact post 763 of the tail pad 730, driving the lower connecting pipe 762 to move downwards, automatically inserting into the interface of the split air pipe 340 of that layer (bottom layer) or the upper connecting pipe 761 of the lower tail pad (upper layer), achieving automatic air path connection. This process is repeated to complete the alternating stacking of multiple layers of ship plates and the laying of pads.

[0060] S4. Ventilation and dehumidification during storage: External hot air enters the internal air channel of each layer pad assembly 700 through the main air pipe 310 and the branch air pipes 340 of each layer via the connected air guiding system, and is finally discharged evenly from the exhaust holes 750 on the side of all pads, directly blowing through the gaps between the ship plates of each layer, achieving efficient and dead-angle-free synchronous dehumidification.

[0061] S5. Integrated Unloading and Loading: The truck drives into the unloading trough 120. The magnetic transfer component 250 moves into the stacking rack, and the electromagnetic suction plate 254 attracts the top layer of ship plate and the pad assembly 700 fixed therewith, lifting and transferring the whole assembly to the truck bed. The pad assembly 700 continues to serve as a separator after loading, eliminating the need for additional installation, thus realizing the reuse of pads and automated unloading throughout the entire process from storage to loading.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
