Description

Technical Field

[0001] The utility model belongs to the technical field of warehouse management, in particular to an automatic steering type two-way warehouse device. Background Art

[0002] In modern logistics and warehousing management, improving storage efficiency and safety is a constant pursuit. Prior art, such as the "Pallet High-Level Storage Method and Warehousing System" disclosed in Chinese Patent CN116986236A, proposes a specific storage structure design. This structure places the inbound and outbound locations on the same side of the warehouse, simplifying the operational process to a certain extent. However, this design also presents some limitations.

[0003] 1. To facilitate the storage and retrieval of goods, this technical solution relies on a large number of mobile forklifts to improve operational flexibility. Frequent movement of forklifts between racks is crucial for achieving storage and retrieval, but it also increases operational complexity and risk. When forklifts navigate narrow aisles, there is a potential for collisions with racks or other forklifts, which can damage goods and pose a threat to operator safety.

[0004] 2. Due to the high risk of forklift operation, the system's safety performance is not ideal. In a high-density storage environment, the use of forklifts increases the probability of accidents, thereby reducing the overall safety factor.

[0005] 3. Using multiple mobile forklifts will increase equipment use and maintenance costs.

[0006] To address these issues, an improved solution has been proposed in the prior art: a dual-sided storage warehouse design. In this design, the entry and exit points are located on opposite sides of the warehouse, and a single stacker crane is used to access goods from the shelves. This design significantly reduces the use of forklifts, thereby reducing the safety risks associated with forklift operations.

[0007] However, whether using a forklift to store and retrieve goods from the shelves or this double-sided storage warehouse design has a shortcoming, that is, since the goods stored in the warehouse are generally stored in a stacked manner to reduce the floor space, the stacked goods are also transported in batches when moving the goods; but when some goods have specified conveying and output direction requirements, direct access may cause the storage direction of the goods to be inconsistent with the retrieval direction. For example, the goods have an identification QR code, and when they are stored, the QR code is located on the side close to the operator or the operating table; at the entry point, it is directly transferred and stored in the designated storage room of the warehouse by a stacker and stored for a period of time, and then directly taken out by the stacker, and then moved to the exit point to be removed from the warehouse. The QR code will be on the side away from the operator, which makes it inconvenient to scan the code again. In addition to the QR code, some goods have a specific form of identification or marking to indicate the direction. Because the entry and exit of goods have fixed direction requirements, the above two existing technologies both have problems that affect the direction of goods leaving the warehouse and the efficiency of transportation.

[0008] Therefore, designing an automatic steering two-way storage device is an important technical problem that those skilled in the art need to solve. Utility Model Content

Furthermore, in the description of the scheme, with the operator as a reference, the direction closer to the operator is referred to as the proximal end, and the direction away from the operator is referred to as the distal end.

[0035] The utility model discloses an automatic steering two-way storage device, such as Figure 1 As shown, a warehouse is provided with an entry point 11 and an exit point 12, and the entry point 11 and the exit point 12 are arranged on opposite sides of the warehouse and on the same axis. By arranging the entry point 11 and the exit point 12 opposite each other and on the same axis, the process of turning or transferring is reduced, and the goods are conveniently transported in and out of the warehouse.

[0036] like Figures 1 to 4 As shown, the entry and exit points 11 and 12 are provided with an entry and exit lifting mechanism 4 and a cargo placement platform 41. Figure 7 As shown, the in-and-out lifting mechanism 4 includes a first drive motor 401 mounted at the top of the warehouse, two sets of transmission gears 403 connected by transmission rollers 402, and two conveyor belts 404 extending along the height of the warehouse and connected to the transmission gears 403. The cargo placement platform 41 is fixedly connected to the straight sections of the conveyor belts 404 and is driven up and down by the in-and-out lifting mechanism 4.

[0037] Further, combined Figure 2 and Figure 7 As shown, the cargo placement platform 41 is slidably mounted on a guide post 411, which is symmetrically disposed outside the in-and-out lifting mechanism 4 and parallel to the conveyor belt 404. The cargo placement platform 41 is provided with a sensor for detecting the presence of cargo thereon. The sensor may be a known infrared sensor or proximity sensor, etc., which is not limited here.

[0038] Specifically, in the initial state, the cargo placement platform 41 is located below the guide column 411; the conveyor drives the cargo to the storage point 11. The first drive motor 401 on the in-and-out lifting mechanism 4 is activated, driving the transmission gear 403 to rotate. The transmission roller 402 drives the two sets of transmission gears 403 to rotate synchronously, thereby driving the two conveyor belts 404 to rotate, so that the cargo placement platform 41 connected to the transmission belts 404 moves upward until the cargo placement platform 41 contacts the bottom of the cargo and the sensor detects the presence of the cargo. The first drive motor 401 continues to drive the cargo placement platform 41 upward until the cargo is separated from the conveyor and enters the storage state.

[0039] Combine Figure 2 and Figure 8 As shown, a cargo limiting mechanism 5 is provided on the outside of the cargo placement platform 41. The cargo limiting mechanism 5 is fixedly connected to the outer wall of the warehouse via a mounting plate 50 and includes a limiting cylinder 51 fixed to the mounting plate 50 and a limiting plate 52 fixed to the output end of the limiting cylinder 51. The limiting plate 52 is arranged parallel to the mounting plate 50 and is driven by the limiting cylinder 51 to move relative to the cargo to limit one pair of side walls of the cargo. Furthermore, at least two cylinders 521 and a clamping plate 522 fixed to the output end of the cylinder 521 are fixed to the limiting plate 52. After the cylinder 521 is activated, the clamping plate 522 can be driven to limit the other pair of side walls of the cargo. Furthermore, the cylinder 521 is preferably a rotating and telescopic cylinder that can adapt to cargo of different sizes without affecting the transportation of the cargo. It can be seen that after the goods are started on the goods placement platform 41, the limiting cylinder 51 and the cylinder 521 on the goods limiting mechanism 5 limit the length and width directions of the goods to ensure the stability of the goods placement position and the lifting process.

[0040] like Figure 1 As shown, at least one buffer point 2 for temporarily storing goods is located between the entry point 11 and the exit point 12. The buffer point 2 is equipped with a transfer and diversion mechanism 21. The transfer and diversion mechanism 21 moves goods from the entry point 11 to the buffer point 2 and rotates the direction of storage. The transfer and diversion mechanism 21 diverts goods from the cargo placement platform 41 to the buffer point 2 for direct shipment later and facilitates direct handling of the goods after shipment. This reduces the need for manual diversion of goods after shipment, improving work efficiency and safety.

[0041] Specifically, the cache point 2 is provided with the following Figure 5The fixed base 20 shown in the figure has a steering assembly 22 provided on the fixed base 20. The steering assembly 22 includes a first servo motor 221 fixedly connected to the fixed base 20, a driving gear provided at the output end of the first servo motor 221, and a driven gear meshing with the driving gear; the driven gear is provided at the center of the fixed base 20; and a rotating frame 201 is provided above the driven gear.

[0042] The rotation angle of the steering assembly 22 is 90° or 180°; that is, the driven gear in the steering assembly 22 drives the rotating frame 201 to rotate 90° or 180°. In other embodiments, the rotation angle of the steering assembly 22 can also be other angles, which can be adjusted according to usage requirements.

[0043] like Figure 3 and Figure 5 As shown, the top of the rotating frame 201 is connected to the supporting base 24 via a transfer assembly 23; the transfer assembly 23 and the steering assembly 22 constitute the transfer and steering mechanism 21. The transfer assembly 23 includes a transfer motor 231 and a telescopic frame 232 that is driven to extend and retract by the transfer motor 231. The supporting base 24 is fixedly mounted on the telescopic frame 232. The transfer motor 231 drives the supporting base 24 to reciprocate between the cargo placement platform 41 and the rotating frame 201 to facilitate cargo handling.

[0044] Before the transfer and steering mechanism 21 is activated, the in-and-out lifting mechanism 4 drives the cargo placement platform 41 to move above the support seat 24, and then the transfer and steering mechanism 21 is activated. The working process of the transfer and steering mechanism 21 is as follows: first, the transfer assembly 23 works, the transfer motor 231 is activated, and the telescopic frame 232 is driven to move toward the cargo placement platform 41 until the support seat 24 is directly below the cargo placement platform 41. The cargo placement platform 41 is driven down by the in-and-out lifting mechanism 4 to place the cargo on the support seat 24. After the cargo is completely separated from the cargo, the transfer motor 231 drives the telescopic frame 232 to return to its original position, and the cargo is moved to the cache point 2. Then start the steering assembly 22 and the first servo motor 221 to drive the driving gear to rotate, thereby driving the driven gear meshing with it to rotate. After the driven gear rotates, it drives the rotating frame 201 fixedly connected to it to rotate. Then, the rotating frame 201 drives the telescopic frame 232 and the supporting seat 24 fixedly connected to it to rotate a specified angle, so that the mark on the cargo is close to the operating position of the personnel for subsequent operation.

[0045] like Figure 1 and Figure 4As shown, a stacker 3 is installed outside the cache point 2. The stacker 3 transfers the goods from the cache point 2 to the storage room of the warehouse and travels back and forth between the entry point 11 and the exit point 12. Using the stacker 3 instead of a mobile forklift reduces reliance on mobile forklifts, effectively avoids turning and U-turns during transportation, shortens the number of paths for goods to enter and exit the warehouse, and reduces collisions, thereby improving safety.

[0046] Specifically, the stacker 3 includes: Figure 6 The frame 30 shown, the lifting mechanism 31 and the transfer pallet 32 ​​arranged on the frame 30. The lifting mechanism 31 includes a lifting motor 311, a screw rod 312 and a guide rail 313 arranged along the height direction of the frame 30. The transfer pallet 32 ​​is slidably connected to the screw rod 312 and the guide rail 313 through a movable plate 314, and is driven up and down by the lifting motor 311. In order to ensure the stability of the lifting process, it is preferably provided with two screw rods 312 and two groups of guide rails 313, and a rotating gear is provided at the bottom of each screw rod 312. The two rotating gears are connected by a belt, and one of the rotating gears is connected to the output gear at the output end of the lifting motor 311 through a belt, so that the two screw rods 312 can be driven by the lifting motor 311 to rotate synchronously, thereby realizing the sliding of the transfer pallet 32 ​​on the screw rod 312 and the guide rail 313.

[0047] Further, such as Figure 5 As shown, the transfer tray 32 is composed of a base 321 and a telescopic plate 322 ; both sides of the base 321 are fixedly connected to the movable plate 314 ; a second servo motor 323 is provided on the telescopic plate 322 and is driven by the second servo motor 323 .

[0048] After the goods to be stored are moved and rotated by the transfer and steering mechanism 21, the stacker 3 begins to work. The lifting mechanism 31 is activated, and the lifting motor 311 drives the transfer pallet 32 ​​upward to a position at the same height as the support seat 24. The second servo motor 323 is then activated to drive the telescopic plate 322 to move directly below the support seat 24 and lift the goods. The goods are finally completely placed on the telescopic plate 322 under the drive of the lifting motor 311. From then on, the goods will be driven by the stacker 3 to move back and forth along the axis of the entry point 11 and the exit point 12. After reaching the designated storage position, the second servo motor 323 will drive the telescopic plate 322 to move away from the cache point 2 to store the goods in the storage room.

[0049] like Figure 2 and Figure 5As shown, the bottom end of the stacker 3 is slidably set on the slide rail 54, and the setting direction of the slide rail 54 is perpendicular to the telescopic direction and the moving direction of the telescopic plate 322. A rack 55 consistent with its setting direction is set in the slide rail 54, and a gear meshing with the rack 55 is also set on the frame 30, and the gear is connected to the output end of the second drive motor 53. The second drive motor 53 drives the frame 30 to move to realize the transfer of goods between the entry point 11, the storage room and the exit point 12. Through the cooperation of the rack 55 and the second drive motor 53, the stacker 3 is automatically driven to move in a straight line direction, and then cooperated with the slide rail 54 to ensure the movement stability of the stacker 3, while reducing the friction during the movement, making the movement process smoother and improving the transplanting efficiency.

[0050] Therefore, under the premise of ensuring operational safety, the utility model optimizes the cargo storage and retrieval process, reduces dependence on mobile forklifts, and solves the problem that traditional storage methods cannot be used due to specially marked cargo.

[0051] There are many implementation methods for the present utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present utility model.
