Description

Technical Field

[0001] This utility model relates to the field of warehousing technology, and in particular to a pull-out heavy-duty rack with semi-automatic storage and retrieval operation. Background Technology

[0002] In the motor repair industry, due to the wide variety of motors of different sizes, especially the large number of loose parts generated after disassembly, the placement and use of these parts are very messy and inefficient.

[0003] The warehousing industry typically employs two storage methods: highly automated stacking warehouse racking and manual stacker cranes that place goods onto the racks. Both methods require placing items on pallets, which are then moved onto the racks using forklifts or automated stacker cranes. Due to the fixed dimensions of the pallets, the actual space utilization of these racks is low, and they are not suitable for the efficient storage of motors and their components, as required in the motor repair industry.

[0004] Chinese patent document CN119190683A discloses a heavy-duty drawer-type rack for warehousing and its usage method, proposing a method that combines with overhead crane transportation, suitable for storing items of different shapes, sizes and weights, individually or in combination within a single bay's roller pallet. However, this solution is a manual storage method, which is inefficient; at the same time, it is limited by the operation mode of the electric hydraulic forklift, requiring a large aisle area. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a semi-automatic pull-out heavy-duty rack. This rack overcomes the defects of traditional racks. Several tons of heavy objects can be placed alone or mixed in the roller pallet of a single compartment, maximizing the use of the pallet area, improving the utilization rate of rack space, reducing the floor space occupied by warehousing operations, realizing semi-automatic storage and retrieval of palletized heavy objects, and improving warehousing operation efficiency and management level.

[0006] To solve the above-mentioned technical problems, the present invention provides a semi-automatic pull-out heavy-duty shelving unit comprising a shelving body consisting of four uprights and a crossbeam frame at the top of the four uprights. Guide rails are symmetrically spaced along both sides of the shelving body in a vertical direction. Each end of the guide rail is provided with a load-bearing block and a rear stop block. Rollers are spaced apart on both sides of the rear of the pallet bottom, load-bearing surfaces are spaced apart on both sides of the front, and a traction block is located in the center of the front. The pallet is positioned on two guide rails at the same horizontal plane, and the rollers on the bottom of the pallet slide along the guide rails. The load-bearing blocks and rear stop blocks respectively limit the sliding movement of the rollers, allowing the pallet to close within the shelving unit. The load-bearing surface is located on the load-bearing block. The forklift is located on the front side of the rack body, and the forklift arm has traction slots on both sides. The traction slots match the traction blocks on the bottom of the pallet. The rack bodies are arranged in rows, and the adjacent rack bodies form a storage channel. It also includes a control panel that is connected to the forklift. The control panel is located on one side of the rack body and contains the pallet location code and goods list of the rack body. The control panel inputs the location code information of the goods to be stored or retrieved, and outputs corresponding instructions to the forklift. The forklift stores or retrieves the corresponding goods according to the location code information.

[0007] Furthermore, the forklift is equipped with a video probe, and the control panel has a built-in database of cargo images. When the forklift retrieves cargo from the pallet, the video probe captures cargo images and transmits them to the control panel. The control panel compares the cargo images captured by the video probe with the cargo images to be stored in the database. If they match, the forklift stores or retrieves the corresponding cargo according to the storage location code information; otherwise, the control panel sends an error message.

[0008] Furthermore, the forklift operates along the storage aisle between adjacent rack bodies, and the fork arms are mounted on both sides of the forklift along the operating direction via lifting seats.

[0009] Furthermore, the shovel arm is a telescopic shovel arm. When the forklift is running along the storage channel, the shovel arm retracts into the lifting seat. When storing or retrieving goods, the shovel arm extends to the bottom of the corresponding pallet and the traction slot hooks onto the traction block on the bottom of the pallet.

[0010] Furthermore, the control panel is equipped with a touch screen display.

[0011] Because this utility model of a semi-automatic pull-out heavy-duty rack adopts the above-mentioned technical solution, the rack includes a rack body, guide rails symmetrically arranged on both sides inside the rack body, load-bearing blocks and backstops respectively provided at both ends of the guide rails, rollers spaced apart on both sides of the rear part of the bottom surface of the pallet, load-bearing surfaces spaced apart on both sides of the front part, and a traction block in the center of the front part. The pallet is located on two guide rails on the same horizontal plane, and the rollers on the bottom surface of the pallet slide along the guide rails. The load-bearing blocks and backstops respectively limit the sliding of the rollers. When the pallet is closed in the rack body, the load-bearing surface is located on the load-bearing block. The forklift is located on the front side of the rack body, and the traction groove on the surface of the forklift arm matches the traction block on the bottom surface of the pallet. The rack bodies are arranged in rows, and storage channels are formed between adjacent rack bodies. The forklift is connected to the control panel, which is located on one side of the rack body and contains the pallet location code and goods list inside the rack body. The control panel inputs the location code information of the goods to be stored or retrieved, and outputs corresponding instructions to the forklift. The forklift stores or retrieves the corresponding goods according to the location code information. This racking system overcomes the shortcomings of traditional racking systems. It allows for the storage of several tons of heavy items, either individually or in combination, within the roller pallets of a single storage location. This maximizes the use of pallet area, improves racking space utilization, reduces the floor space required for warehousing operations, enables semi-automatic storage and retrieval of palletized heavy items, and enhances warehousing efficiency and management.

[0016] Figure 4 This is a schematic diagram of the actual application of this shelf. Detailed Implementation

[0017] Implementation, for example Figure 1 , Figure 2 and Figure 3As shown, the semi-automatic pull-out heavy-duty shelving of this utility model includes a shelving body 1 consisting of four uprights 11 and a crossbeam frame 12 at the top of the four uprights 11. Guide rails 2 are symmetrically arranged on both sides of the interior of the shelving body 1 at intervals along the vertical direction. Each end of the guide rail 2 is provided with a load-bearing block 21 and a rear stop block 22. The bottom surface of the pallet 3 has rollers 31 spaced apart on both sides at the rear, load-bearing surfaces 32 spaced apart on both sides at the front, and a traction block 33 in the center of the front. The pallet 3 is located on two guide rails 2 at the same horizontal plane, and the rollers 31 on the bottom surface of the pallet 3 slide along the guide rails 2. The load-bearing blocks 21 and the rear stop blocks 22 respectively limit the sliding movement of the rollers 31. The pallet 3 closes within the shelving body. The load-bearing surface 32 of the rack body 1 is located on the load-bearing block 21. The forklift 4 is located on the front side of the rack body 1, and the forklift arm 41 has traction slots 42 on both sides of its surface. The traction slots 42 match the traction blocks 33 on the bottom of the pallet 3. The rack bodies 1 are arranged in rows, and the adjacent rack bodies form a storage channel. The rack body 1 also includes a control panel 5 that is communicatively connected to the forklift 4. The control panel 5 is located on one side of the rack body 1 and contains the storage location code and goods list of the pallet 3 in the rack body 1. The control panel 5 inputs the storage location code information of the goods to be stored or retrieved, and outputs the corresponding instructions to the forklift 4. The forklift 4 stores or retrieves the corresponding goods according to the storage location code information.

[0018] Preferably, the forklift 4 is equipped with a video probe 43, and the control panel 5 has a built-in database of cargo images. When the forklift 4 retrieves cargo from the pallet 3, the video probe 43 captures cargo images and transmits them to the control panel 5. The control panel 5 compares the cargo images captured by the video probe 43 with the cargo images to be retrieved in the database. If they match, the forklift 4 retrieves the corresponding cargo according to the storage location code information; otherwise, the control panel 5 sends an error message. By capturing cargo images with the video probe and comparing them with the cargo images to be retrieved in the database, the accuracy of cargo retrieval is ensured, and errors in cargo retrieval are avoided.

[0019] Preferably, the forklift 4 runs along the storage aisle between adjacent rack bodies 1, and the fork arms 41 are mounted on both sides of the forklift 4 along the running direction via lifting seats 44. This fork arm configuration allows the forklift to travel straight along the storage aisle without needing to turn to face the pallets inside the rack body, saving floor space for storage operations.

[0020] Preferably, the shovel arm 41 is a telescopic shovel arm. When the forklift 4 is running along the storage channel, the shovel arm 41 retracts into the lifting seat 44. When storing or retrieving goods, the shovel arm 41 extends to the bottom surface of the corresponding pallet 3 and the traction slot 42 hooks onto the traction block 33 on the bottom surface of the pallet 3.

[0021] Preferably, the control panel 5 is equipped with a touch screen display 51. Inputting relevant information and instructions via the touch screen improves warehouse operation efficiency and management level.

[0022] This racking system enables semi-automatic storage and retrieval of goods. Each layer of the racking system has a coded storage location on its roller pallet. The forklift is an electric hydraulic stacker with automatic movement and lifting arm. The forklift arm is a telescopic arm that folds 90 degrees along the forklift's running direction. The control panel has a touch screen display.

[0023] like Figure 4 As shown, when storing or retrieving goods, the control panel 5 stores the storage location code. The storage location code is entered through the touch screen 51, and the pallet 3 indicated by the storage location code is selected. The forklift 4 then controls the storage or retrieval of goods in the pallet of that storage location.

[0024] In the inbound / outbound operation, when heavy goods 6 are inbound or outbound, the "inbound / outbound" command of the required pallet 3 location code is entered into the control panel 5. The control panel 5 sends the corresponding command to the forklift 4. The forklift 4 automatically moves to the set position of the location. According to the location code and the pallet 3 indicated in the goods list, the telescopic arm 41 is automatically raised to the pallet 3 of the location under the support of the lifting seat. The slot of the telescopic arm 41 is engaged with the traction block at the front end of the pallet 3. The telescopic arm 41 is then raised slightly upwards according to the set distance value, so that the front end of the pallet 3 is lifted. When the telescopic arm 41 retracts backward, the two rear rollers of the pallet 3 slide outward along the guide rail, pulling out the pallet 3. After the pallet 3 is pulled out, the heavy goods 6 are manually placed into the pallet 3 using the hoisting sling 7, or the heavy goods 6 in the pallet 3 are lifted out.

[0025] After the above-mentioned heavy cargo is stored and retrieved, the "close" command of the pallet 3 compartment code is entered on the touch screen 51 of the control panel 5. The telescopic shovel arm 41 extends and pushes the roller pallet 3 back to its original position. The telescopic shovel arm 41 then descends, so that the front end of the pallet 3 is lowered, the slot is disengaged from the traction block, the telescopic shovel arm 41 retracts, and the forklift 4 stays in place or returns to its initial position.

[0026] Currently, existing automated stacking warehouses allow only one item to be stored in each coded storage location. The items are automatically identified for entry and exit through QR codes or other markings, making them fully automated.

[0027] The pallet compartments of this racking system use a mixed-packing method, meaning that pallets in one compartment can contain goods of different sizes, types, and shapes. It is impossible to use a single QR code to identify all items. Furthermore, disassembled parts of the same motor, such as rotors, stators, and end caps, may not necessarily be stored in the same pallet compartment, requiring manual intervention for entry and exit.

[0028] Therefore, when entering or leaving the warehouse, the information of the stored items can be entered into the designated coded compartment by controlling the touch screen of the control panel. For example, taking motor parts as an example: compartment A1 contains "cold-rolled 100KW end cap", "hot-rolled 75KW stator", "silicon steel 50KW rotor", etc., and compartment A2 contains "cold-rolled 100KW stator", "hot-rolled 75KW rotor", "silicon steel 50KW end cap", etc.

[0029] Outbound: When operators retrieve items, such as "cold-rolled 100KW end cap," they can input the item information or keywords into the control panel. For precise keyword input, "cold-rolled 100KW end cap" will bring up option A1 on the operation interface. Pressing the "Outbound" button will allow a forklift to pull out the drawer-type pallet, and an overhead crane to lift the component. If the exact component name is unknown, a range of keywords, such as "cold-rolled 100KW," can be entered. The touchscreen will display two pallet number options, A1 and A2. Select the desired pallet and click "Outbound." After retrieval, delete the item information.

[0030] This shelving is not limited to warehousing and retrieval in the motor repair industry; it is also suitable for warehousing and retrieval of heavy objects in other workshops or sites with cranes.
