Description

Technical Field

[0001] This invention relates to the field of automated storage and retrieval systems (AS / RS), and more specifically, to an automated AS / RS for temporary storage of garlic in cold storage. Background Technology

[0002] Cold storage refers to a specialized storage building or container that uses artificial refrigeration to keep the internal temperature stable below 0℃, used to delay the deterioration of perishable products such as food, medicine, fruits and vegetables, flowers, and chemical raw materials and extend their shelf life. When storing garlic, an automated three-dimensional warehouse is used. The garlic stack racks are transferred to liftable three-dimensional storage units, and automated storage and retrieval are achieved through the robot body and gripping components, replacing the traditional ground stacking. The vertical transportation of the stack racks loaded with garlic is achieved through the lifting platform in the racks, realizing three-dimensional storage. A search revealed that CN114013898B discloses an automated warehousing system for industrial robots, relating to the field of warehousing system devices. The invention includes a conveyor belt, a robot body, and / or a shelf. Pallets are mounted on the conveyor belt, and the robot body can grasp the pallets and place them on the shelf. A gripping component is located at the front end of the robot body's arm, capable of clamping the pallets and automatically releasing the clamp. The shelf is equipped with a movable, liftable placement plate, and a lifting component is provided to control the lifting and moving of the plate. After the lifting rack is lifted, it needs to be locked. The locking operation is completed by electromagnetic attraction. The existing locking device is arranged at two points at the four corners. Due to the asymmetrical stacking of garlic, the roots face one side when stacking manually, which causes the center of mass of the stack to shift laterally. This causes the locking structure to be unable to effectively lock the lifting platform when the load on the load-bearing platform is uneven, which can easily lead to the falling of goods and the moving platform. Based on this, the present invention discloses an automated three-dimensional warehouse for temporary storage of garlic cold storage. Summary of the Invention

[0003] To address the issue raised in the background art, existing lifting racks require locking after lifting and then electromagnetic engagement to complete the locking operation. Current locking devices, arranged at two points at the four corners, suffer from problems due to asymmetrical garlic stacks. When manually stacking, the base of the garlic stack faces one side, causing a lateral shift in the center of mass of the stack. This results in the locking structure failing to effectively lock the lifting platform under uneven load conditions, potentially leading to the fall of goods and the moving platform. A new solution addresses this by using three locking rods acting on both ends and the middle of the movable pallet, engaging with corresponding slots in the limiting steel plate to form a six-point locking system. This eliminates asynchronous errors caused by uneven garlic stack loads, preventing uneven loading and creep. Furthermore, the double-sided clamping structure of the limiting rods and locking rods suppresses swaying of the movable pallet along the connecting beam and the hollow square tube axis, ensuring that the fully loaded garlic stack does not tilt or slip during lifting, locking, or long-term static periods.

[0004] This invention provides an automated three-dimensional warehouse for temporary storage of garlic cold storage, including a warehouse body and a three-dimensional storage rack. The three-dimensional storage rack is installed in the warehouse body. The three-dimensional storage rack is composed of a three-dimensional storage panel and storage legs forming an integral frame. Storage legs are vertically welded to the bottom side of the three-dimensional storage panel. The six vertical storage legs are arranged in a rectangle to form a vertical lifting range. The movable pallet is provided in the lifting range of the storage leg and moves vertically. The movable pallet is used to carry and support the goods on the pallet. A limit steel plate is vertically fixed on one side of the storage leg and the limit steel plate has slots at equal intervals along the vertical direction. The lifting structure is installed on the top of the three-dimensional storage rack. A lifting frame is provided at the top of the top of the lifting range of the storage legs. The lifting structure is used to lift the lifting frame. Three movable trays are arranged side by side below the lifting frame. The lifting frame is connected to the adjacent movable tray below by a connector. Two movable trays in the vertical direction are connected by a connector. A limiting locking structure is installed on the movable support plate, and the locking rod in the limiting locking structure is engaged in the slot of the limiting steel plate.

[0005] As a further improvement to this technical solution, the movable pallet includes a hollow square tube and connecting beams. Three connecting beams are fixed at equal intervals between the two hollow square tubes. Both hollow square tubes are located on the inner side of the storage legs on both sides. Three swing grooves are opened at equal intervals inside the hollow square tubes. Three arc-shaped holes are opened at equal intervals on the upper wall of the hollow square tubes.

[0006] The limiting and locking structure includes a pressing rod, a spring, a movable cap, a fixed plate, a movable rod, and a swing plate. The swing plate is hinged in the swing groove by a pin. The pressing rod is fixed on the top side of the swing plate and is slidably disposed in the arc-shaped hole. The fixing plate is fixed to the top side of the hollow square tube. The fixing plate has a rod hole, and a movable rod is movably inserted through the rod hole. One end of the movable rod is fixed with a locking rod, and the pressing rod is located between the locking rod and the fixing plate. The other end of the movable rod is fixed with a movable cap, and a spring is fixed between the movable cap and the fixed plate. The two ends of the spring are respectively fixed on the opposite surfaces of the movable cap and the fixed plate. The locking rod has a C-shaped structure with vertical bends at both ends, which are in close contact with the side of the limiting steel plate.

[0007] As a further improvement to this technical solution, the limiting and locking structure includes a pressing rod, a spring, a movable cap, a fixed plate, a movable rod, and a swing plate. Three swing grooves are equally spaced inside the hollow square tube. A swing plate is hinged to the swing grooves by a pin. Three arc-shaped holes are equally spaced on the upper side wall of the hollow square tube. A pressing rod is fixed to the top side of the swing plate. The pressing rod is slidably disposed in the arc-shaped holes. A fixing plate is fixed to the top side of the hollow square tube. A rod hole is opened on the fixing plate, and a movable rod is movably inserted through the rod hole. A locking rod is fixed to one end of the movable rod, and the pressing rod is located between the locking rod and the fixing plate. The other end of the movable rod is fixed with a movable cap, and a spring is fixed between the movable cap and the fixed plate. The two ends of the spring are respectively fixed on the opposite surfaces of the movable cap and the fixed plate. The locking rod has a C-shaped structure with vertical bends at both ends. These bends are close to the side of the limiting steel plate, which can prevent the movable support plate from swaying along the connecting beam axially.

[0008] As a further improvement to this technical solution, the limiting and locking structure also includes a linkage rod and a push plate. The linkage rod is set inside a hollow square tube, and three push plates are fixed at equal intervals on the side of the linkage rod. Each push plate is correspondingly set on one side of each swing plate, and the same push plate is welded to the same end of the push plates in the two hollow square tubes.

[0009] As a further improvement to this technical solution, an electric cylinder is installed on the connecting beam near the push plate, and the piston rod of the electric cylinder passes through the interior of the connecting beam and is fixed in the middle of the push plate.

[0010] As a further improvement to this technical solution, a sliding buckle is fixed to the bottom side of the locking rod, and the sliding buckle is slidably sleeved on the outside of the hollow square tube.

[0011] As a further improvement to this technical solution, a support base is fixed to the top side of the fixing plate, and a positioning groove is provided on the support base.

[0012] As a further improvement to this technical solution, the lifting structure includes a fixed frame, a winch, a winding shaft, and a hoisting motor. Two fixed frames are welded to the top side of the three-dimensional storage panel, and a winding shaft is rotatably installed between the two fixed frames. Two winches are symmetrically installed on the outer side of the winding shaft. A hoisting motor is also installed on the top side of the three-dimensional storage panel. The hoisting motor is used to drive the winding shaft, and steel wire rope is wound on the winches.

[0013] As a further improvement to this technical solution, a lifting ring is fixed to the top side of the lifting frame, and the lifting ring is bound to the wire rope on the winch. The connecting component includes a lifting lug and a lifting rope. A lifting lug is welded to the outside of the hollow square tube, and a lifting rope is bound above the lifting lug. The lifting frame is connected to the adjacent lifting lug below it by a lifting rope, and the lifting lugs on two adjacent layers of hollow square tubes in the vertical direction are connected by a lifting rope.

[0014] As a further improvement to this technical solution, limit rods are fixed to the outer sides of the two hollow square tubes respectively. The sides of the limit rods are set close to the sides of the storage support legs. An RFID reader is installed on the limit rods. The RFID reader is used to detect the lifting and positioning points. By setting the limit rods, horizontal movement of the movable pallet can be prevented. The limit rods and the locking rod located in the middle act on both sides of the storage support legs, which can prevent the movable pallet from swaying along the axial direction of the hollow square tubes. The two ends of the locking rod are provided with vertical bends. The bends are close to the sides of the limit steel plate, which can prevent the movable pallet from swaying along the axial direction of the connecting beam.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In this type of automated three-dimensional warehouse for temporary storage of garlic cold storage, an electric cylinder operates to drive a push plate, which, in conjunction with a linkage rod, squeezes or releases a swing plate, thereby changing the position of the locking rod and forming an integrated power chain. This allows the locking rod's disengagement or reset action to be linked with the hoisting and lifting: during the lifting phase, the cylinder retracts, the locking rod disengages from the slot, and the movable pallet can be raised and lowered freely; after reaching the desired position, the cylinder extends, and the locking rod automatically engages in the new slot under the spring's reset force and the sliding buckle's guiding action, thus locking upon reaching the desired position. Three locking rods act on both ends and the middle of the movable pallet respectively, and engage with the corresponding slots of the limiting steel plate to form a six-point locking; this eliminates the asynchronous error of single-point disengagement and single-point locking caused by uneven loading of the garlic stack, and avoids uneven loading and creep. At the same time, the double-sided clamping structure of the limiting rods and locking rods can suppress the shaking of the movable pallet along the axial direction of the connecting beam and the axial direction of the hollow square tube, ensuring that the fully loaded garlic stacking rack does not tilt or slip during lifting, locking and long-term static storage, thus improving storage safety. By combining the warehouse body, three-dimensional storage racks, and multi-layer movable pallets, and using a winch driven by a hoisting motor to rotate, the movable pallets of each layer can be lifted independently or synchronously within the vertical lifting range through the cascading lifting of steel wire ropes and hoisting ropes. This achieves three-dimensional three-layer load-bearing hoisting, which avoids the risk of excessive load on the bottom and stacking tipping caused by directly stacking the racks compared to traditional ground stacking.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0018] Therefore, such as Figure 1-13 As shown, the present invention provides an automated three-dimensional warehouse for temporary storage of garlic cold storage, including a warehouse body and a three-dimensional storage rack. The three-dimensional storage rack is installed in the warehouse body. The three-dimensional storage rack is composed of a three-dimensional storage plate 1 and storage support legs 2 forming an integral frame. The storage support legs 2 are vertically welded to the bottom side of the three-dimensional storage plate 1. The six vertical storage support legs 2 are arranged in a rectangle to form a vertical lifting range. The storage leg 2 has a movable pallet that moves vertically within its lifting range. The movable pallet is used to carry and support the goods on the pallet. A limiting steel plate 8 is vertically fixed on one side of the storage leg 2. The limiting steel plate 8 has slots 10 evenly spaced along the vertical direction. The lifting structure is installed on the top of the three-dimensional storage rack. A lifting frame 4 is provided at the top of the top of the lifting range of the storage support leg 2. The lifting structure is used to lift the lifting frame 4. Three movable trays are arranged side by side below the lifting frame 4. The lifting frame 4 is connected to the adjacent movable tray below by a connector. Two movable trays in the vertical direction are connected by a connector. A limiting locking structure is installed on the movable support plate, and the locking rod 38 in the limiting locking structure is engaged in the slot 10 of the limiting steel plate 8.

[0019] When storing garlic, the garlic is first stacked on a garlic stacking rack, and then a forklift is used to transport the stacking rack into the cold storage. The stacking rack is placed on a movable pallet, and the hoisting frame 4 is lifted using a lifting structure. During the lifting process, the movable pallet carrying the stacking rack is pulled up with the help of the connecting parts. During the pulling process, the locking rod 38 disengages from the slot 10 of the limiting steel plate 8. After being pulled up to the correct position, the locking rod 38 automatically engages with the corresponding slot 10 on the same layer to achieve positioning and locking of the movable pallet.

[0020] The movable pallet includes a hollow square tube 31 and a connecting beam 32. Three connecting beams 32 are fixed at equal intervals between two hollow square tubes 31. Both hollow square tubes 31 are located inside the storage legs 2 on both sides. Three swing grooves 318 are opened at equal intervals inside the hollow square tube 31. Three arc-shaped holes 310 are opened at equal intervals on the upper wall of the hollow square tube 31.

[0021] During operation, the movable pallet consists of two hollow square tubes 31 arranged side by side, with three connecting beams 32 welded between the two hollow square tubes 31. The three connecting beams 32 are welded to the two ends and the center of the hollow square tubes 31 respectively, which can be assembled into a rectangular frame to stably support the stacking rack.

[0022] The limiting and locking structure includes a pressing rod 311, a spring 314, a movable cap 315, a fixed plate 316, a movable rod 317, and a swing plate 320. The swing plate 320 is hinged in the swing groove 318 by a pin. The pressing rod 311 is fixed on the top side of the swing plate 320. The pressing rod 311 is slidably disposed in the arc-shaped hole 310. The fixing plate 316 is fixed to the top side of the hollow square tube 31. The fixing plate 316 has a rod hole, and a movable rod 317 is movably inserted through the rod hole. One end of the movable rod 317 is fixed with a locking rod 38. The pressing rod 311 is located between the locking rod 38 and the fixing plate 316. The other end of the movable rod 317 is fixed with a movable cap 315. A spring 314 is fixed between the movable cap 315 and the fixed plate 316. The two ends of the spring 314 are respectively fixed on the opposite surfaces of the movable cap 315 and the fixed plate 316. The locking rod 38 has a C-shaped structure with vertical bends at both ends. The bends are close to the side of the limiting steel plate 8, which can prevent the movable support plate from swaying along the connecting beam 32.

[0023] During operation, when lifting and lowering the loaded stacking rack, the push plates 39 on the hollow square tube 31 move synchronously under the sliding action of the linkage rod 312 within the hollow square tube 31. Under the action of the three push plates 39, three swing plates 320 can be acted on simultaneously. The swing plates 320 swing, causing the pressing rod 311 to slide along the arc-shaped hole 310. During the sliding of the pressing rod 311, the locking rod 38 can be pushed, causing the locking rod 38 to move away from the fixed plate 316. During the movement of the locking rod 38, the movable rod 317 slides within the rod hole in the fixed plate 316, causing the movable cap 315 to move closer to the fixed plate 316. During the movement of the movable cap 315, the spring 314 is compressed, and the compressed spring 314 generates a rebound force. After the locking rod 38 moves away from the fixed plate 316, the locking rod 38 disengages from the slot 10, enabling the movable pallet to move vertically within the lifting range. After the movable plate moves up and down for adjustment, the linkage rod 312 slides back to its original position within the hollow square tube 31, causing the push plate 39 to separate from the swing plate 320. The swing plate 320 loses the squeezing and restraining force of the push plate 39, and under the rebound force of the spring 314, it can push the movable cap 315 back to its original position. With the drive and cooperation of the movable rod 317, it can drive the locking rod 38 to move closer to the fixed plate 316. After the locking rod 38 moves closer to the fixed plate 316, both ends of the locking rod 38 are respectively engaged in the movable cap 315. The slots 10 on the limiting steel plates 8 on both sides of the movable pallet can lock the movable pallet after it has moved. The locked pallet is stably lifted, and the movable pallet after lifting and adjusting is positioned and locked. The locking rods 38 act on the six positions at both ends and the middle of the movable pallet to lock and fix it. This can ensure that the movable pallet has a better support effect after locking and avoid the offset during the stacking process caused by uneven loading of the stacking frame. At the same time, the synchronous locking at the six positions can prevent offset and tilting in the later stages of the stacking operation.

[0024] The limiting and locking structure also includes a linkage rod 312 and a push plate 319. The linkage rod 312 is set inside the hollow square tube 31. Three push plates 319 are fixed at equal intervals on the side of the linkage rod 312. Each push plate 319 is correspondingly set on one side of each swing plate 320. The same push plate 39 is welded to the same end of the push plates 319 in the two hollow square tubes 31. During operation, the linkage rod 312 is set inside the two hollow square tubes 31. During the movement of the push plate 39, it can drive the linkage rods 312 on both sides to slide synchronously in the hollow square tube 31. By pushing the corresponding swing plates 320 simultaneously through the push plates 319 on the linkage rod 312, the three locking rods 38 on the same movable plate can be operated synchronously, making the points on both sides of the movable plate more balanced.

[0025] An electric cylinder 35 is installed on the connecting beam 32 near the push plate 39. The piston rod of the electric cylinder 35 passes through the interior of the connecting beam 32 and is fixed in the middle of the push plate 39. In order to realize the electric locking operation, the electric cylinder 35 operates so that the piston rod can move the push plate 39 by extending and retracting. When locking, the push plate 39 drives the piston rod to retract, so that the push plate 39 moves closer to the connecting beam 32 to complete the locking operation of the movable pallet. When releasing, the push plate 39 drives the piston rod to extend, so that the push plate 39 moves away from the connecting beam 32 to complete the release of the movable pallet, so that the movable pallet can move freely up and down within the lifting range.

[0026] The bottom side of the locking rod 38 is fixed with a sliding buckle 36. The sliding buckle 36 is slidably sleeved on the outside of the hollow square tube 31. During operation, as the locking rod 38 moves, the sliding buckle 36 at its bottom slides along the outside of the hollow square tube 31. The locking rod 38 serves as the locking force point of the movable support plate. Under the action of the sliding buckle 36, the movable support plate is lifted and supported. The top side of the fixed plate 316 is fixed with a support seat 37. The support seat 37 is provided with a positioning groove. When storing garlic, it is necessary to load the garlic using a stacking rack. After loading, the stacking rack is placed on a movable pallet using a forklift. The bottom legs of the stacking rack are inserted into the positioning grooves in the support base 37 so that the movable pallet can stably support the stacking rack.

[0027] The hoisting structure includes a fixed frame 5, a winch 6, a winding shaft 7, and a hoisting motor 9. Two fixed frames 5 are welded to the top side of the three-dimensional storage plate 1. A winding shaft 7 is rotatably installed between the two fixed frames 5. Two winches 6 are symmetrically installed on the outer side of the winding shaft 7. A hoisting motor 9 is also installed on the top side of the three-dimensional storage plate 1. The hoisting motor 9 is used to drive the winding shaft 7. Steel wire rope is wound on the winches 6. During operation, when hoisting the movable pallet, the winch motor 9 drives the winding shaft 7 to rotate, enabling the two winches 6 to work synchronously and allowing the wire ropes on both sides to be wound or released.

[0028] The top side of the hoisting frame 4 is fixed with a lifting ring 11, which is bound to the wire rope on the winch 6. The connecting parts include a hoisting lug 33 and a hoisting rope 34. The hollow square tube 31 is welded with a hoisting lug 33 on the outside. The hoisting lug 34 is bound above the hoisting lug 33. The hoisting frame 4 is connected to the adjacent hoisting lug 33 below it by the hoisting rope 34. The hoisting lugs 33 on two adjacent layers of hollow square tubes 31 in the vertical direction are connected by the hoisting rope 34. During the hoisting process, the hoisting frame 4 is lifted and lowered by the wire rope. The first movable pallet located below the hoisting frame 4 is lifted and lowered first. After the uppermost movable pallet is lifted and lowered, the subsequent stacking frame is placed on the second movable pallet. The second movable pallet then begins to lift and lower. At this time, the first and second sets of movable pallets rise synchronously. After the second movable bracket is raised, the subsequent stacking racks can be placed on the third movable bracket, which can realize three-dimensional three-layer load-bearing hoisting. By raising and lowering the first and second movable brackets, the offset caused by direct stacking of stacking racks and excessive load on the bottom are avoided. When loading with a forklift, the movable brackets are all in a lower position, which facilitates the stacking of forklifts, avoids stacking offset of stacking racks, and avoids deformation of the bottom stacking rack caused by heavy load due to direct stacking of stacking racks, which could lead to the stacking tipping over.

[0029] Limiting rods 321 are fixed to the outer sides of the two hollow square tubes 31 respectively. The sides of the limiting rods 321 are closely attached to the sides of the storage legs 2. An RFID reader 322 is installed on the limiting rods 321. The RFID reader 322 is used to detect the lifting and positioning points. By setting the limiting rods 321, horizontal movement of the movable pallet can be prevented. The limiting rods 321 and the locking rods 38 located in the middle act on both sides of the storage legs 2 to prevent the movable pallet from swaying along the axial direction of the hollow square tubes 31. The locking rods 38 have vertical bends at both ends. The bends are closely attached to the sides of the limiting steel plate 8 to prevent the movable pallet from swaying along the axial direction of the connecting beam 32. The RFID reader 322 can identify preset points during the lifting and lowering of the movable pallet, suspend the movable pallet, and ensure that the locking rod 38 in the limit locking structure is accurately engaged in the slot 10 of the same height, so as to achieve the positioning and locking of the movable pallet.

[0030] This invention combines a warehouse body, a three-dimensional storage rack, and multiple movable pallets. The winch 6 is driven by a hoisting motor 9, and the movable pallets on each layer can be lifted independently or synchronously within the vertical lifting range through the cascading lifting of steel wire ropes and hoisting ropes. This achieves three-dimensional three-layer load-bearing hoisting. Compared with traditional ground stacking, it can avoid the risk of excessive load on the bottom and stacking tipping caused by directly stacking the racks. The electric cylinder 35 operates, driving the push plate 39. With the cooperation of the linkage rod 312, it squeezes or releases the swing plate 320, thereby changing the position of the locking rod 38 and forming an integrated power chain. This makes the disengagement or reset action of the locking rod 38 linked with the hoisting and lifting: during the lifting stage, the cylinder retracts, the locking rod 38 disengages from the slot 10, and the movable support plate can be lifted and lowered freely; after reaching the position, the cylinder extends, and the locking rod 38 automatically engages with the new slot 10 under the reset force of the spring 314 and the guiding action of the sliding buckle 36, thus locking upon reaching the position. Three locking rods 38 act on both ends and the middle of the movable pallet respectively, and engage with the corresponding slots 10 of the limiting steel plate 8 to form a six-point locking. At the same time, the double-sided clamping structure of the limiting rod 321 and the locking rods 38 can suppress the swaying of the movable pallet along the axial direction of the connecting beam 32 and the axial direction of the hollow square tube 31, ensuring that the fully loaded garlic stacking rack does not tilt or slip during lifting, locking and long-term static storage, thus improving storage safety.
