Description

Technical Field

[0001] The present invention relates to the field of warehousing and logistics, and in particular to a shuttle cargo integrated elevator, a storage and retrieval system and an integrated system. Background Art

[0002] Modern industrial production is highly socialized, specialized, and centralized, requiring the timely, rapid, and accurate supply and distribution of materials. This has led to the rapid development of high-bay warehouse technology. With the continuous development of the warehousing industry, more and more industries and enterprises have adopted high-bay warehouses. Lifting equipment is one of the main facilities of high-bay warehouses and an indispensable component of modern industrial warehouses, logistics centers, and distribution centers. Existing lifting equipment is mainly divided into two categories: cargo elevators and shuttle car level change elevators. The layout is that a level change elevator is used in front of the warehouse to lift the shuttle car level change, two cargo elevators are set up at the back of the warehouse, or another cargo elevator is set up in front of the warehouse. The cargo elevator and shuttle car level change elevator are independently driven and controlled, and independently lift goods or shuttle cars. A temporary storage platform is also required between the high-bay warehouse shelves and the cargo elevator (the shuttle car removes the goods from the high-bay warehouse shelves and stores the goods on the temporary storage platform, and the temporary storage platform transfers the goods to the lifting pallet of the cargo elevator). This has the problems of large space occupation and high cost investment. In particular, the high initial investment cost makes the storage management of this type of equipment face severe challenges for enterprises.

[0003] In addition, with the rapid development of the warehousing industry, the requirements for the efficiency of cargo box storage, outbound, picking and return are getting higher and higher. More and more industries and enterprises are using vertical warehouses and goods-to-person picking stations. A complex conveyor line is set between the vertical warehouse and the goods-to-person picking station. The cargo box is transported from the vertical warehouse to the goods-to-person picking station through the conveyor line. After picking, the cargo box is transported back to the vertical warehouse through the conveyor line. This structure of the warehousing and sorting system also has problems such as low outbound and return efficiency, complex outbound picking and return processes, large space occupation and high cost investment. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned problems and provides an integrated shuttle cargo elevator, storage and retrieval system and integrated system. The elevator has dual functions by setting an integrated lifting unit, which can realize the function of shuttle car changing floors and the function of transporting goods. The shuttle car lifting tray and the cache platform share a driving system to realize the function of simultaneous lifting, which greatly reduces the occupied space and the difficulty of equipment installation, and reduces the investment cost of the elevator. The storage and retrieval system can realize the transfer of goods between the shuttle car and the cache platform, the transfer of goods between the shuttle car and the temporary storage platform, and the transfer of goods between the temporary storage platform and the cache platform through the ingenious design of the elevator and the ingenious layout of the entire system.

[0037] In order to better understand the technical content of the present invention, specific embodiments are given and described below in conjunction with the above-mentioned drawings.

[0038] According to a preferred embodiment of the present invention, a shuttle car cargo integrated elevator is proposed. The elevator is suitable for the lifting operations of the shuttle car vertical warehouse system in the field of warehousing and logistics. It is specifically used for changing layers for shuttle cars and performing lifting operations of goods or cargo boxes (such as cartons or turnover boxes). The elevator has an integrated design, saves space, and greatly reduces costs.

[0039] like Figures 1 to 5 As shown, the elevator is used in conjunction with a shuttle car vertical warehouse system. In order to explain the elevator more clearly, the shuttle car vertical warehouse system is briefly introduced here. The shuttle car vertical warehouse system (the vertical warehouse system is also referred to as the storage and retrieval system 1 in this patent application) has multi-layer shelves 1-1 and a shuttle car 1-3. The storage and retrieval system 1 can flexibly and symmetrically set two rows of multi-layer shelves 1-1. The two rows of multi-layer shelves 1-1 are parallel to each other and form an alley 1-2. The shuttle car 1-3 runs in the alley 1-2. The shuttle car alley 1-2 has a first alley position 1-2a and a second alley position 1-2b. The shuttle car 1-3 has a telescopic fork, which can be extended and retracted in both directions to store and retrieve goods or cargo boxes 3 (such as cartons or turnover boxes).

[0040] The elevator includes a power system and a lifting unit 2. The lifting unit 2 is controlled by the power system for lifting and lowering. The lifting unit 2 includes a shuttle lift tray 2-3 for transporting shuttles 1-3 and at least one set of buffer platforms for transporting goods or cargo boxes 3 (such as cartons or turnover boxes). The shuttle lift tray 2-3 and the buffer platforms 2-1 and 2-2 are integrated, forming a single unit and sharing a common drive system for synchronous lifting and lowering.

[0041] It should be noted that the shuttle vehicles 1-3 and the aforementioned power system are well known in the art, and any existing or future developed appropriate structure may be used according to the disclosure of the present invention.

[0042] To further illustrate the hoist, refer to Figures 1 to 5 The schematic diagram of the top view layout is taken as an example of an elevator including two groups of cache platforms 2-1 and 2-2. The two groups of cache platforms 2-1 and 2-2 are arranged side by side on both sides of the shuttle lift tray 2-3; the two groups of cache platforms 2-1 and 2-2 are roller conveyors. Of course, the two groups of cache platforms 2-1 and 2-2 can also be replaced by other types of conveying mechanisms. Each group of cache platforms 2-1 and 2-2 can allow at least two pieces of cargo or cargo boxes 3 to be placed at the same time, playing a caching role. When the shuttle 1-3 needs to change layers, the shuttle 1-3 drives out of the shuttle warehouse system along the shuttle lane 1-2 and moves to the shuttle lift tray 2-3 (such as Figure 2 When the shuttle 1-3 is located on the shuttle lift tray 2-3 (as shown in FIG. Figure 2As shown), it can dock with the cache platforms 2-1 and 2-2 on both sides to transfer cargo boxes between the shuttle car 1-3 and the cache platforms 2-1 and 2-2 on both sides. In this way, the shuttle car lifting tray 2-3 of the elevator can be used to change the layer of the shuttle car 1-3, and can also be used to provide a support platform for the shuttle car 1-3, so that the shuttle car 1-3 can dock with the cache platforms 2-1 and 2-2 on both sides to store and retrieve goods or cargo boxes 3; the lifting and lowering of the cache platforms 2-1 and 2-2 can realize the lifting and lowering of goods or cargo boxes 3 for transporting goods. Of course, in some preferred embodiments, the shuttle car 1-3 drives out of the shuttle car warehouse system along the shuttle car alley 1-2 without moving to the shuttle car lifting tray 2-3. It only needs to move to a position close to the shuttle car lifting tray 2-3 (that is, the first position 1-2a of the shuttle car alley) to dock with the cache platforms 2-1 and 2-2 on both sides (as shown in FIG. Figure 1 As shown), to transfer cargo boxes between the shuttle vehicle 1-3 and the buffer platforms 2-1 and 2-2 on both sides.

[0043] The working principle of the shuttle cargo integrated elevator proposed in the preferred embodiment of the present invention is now described in detail:

[0044] When it is necessary to take out the goods or the container 3, Figure 1 Combine Figure 2 As shown, the shuttle 1-3 takes out the goods or cargo boxes 3 from the multi-layer shelf 1-1 of the vertical warehouse system and moves it to the first position 1-2a of the shuttle aisle or moves it to the shuttle lifting platform 2-3; the shuttle 1-3 transfers the goods or cargo boxes to the buffer platforms 2-1 and 2-2 of the elevator; the buffer platforms 2-1 and 2-2 drive the goods or cargo boxes 3 to move downward; the goods or cargo boxes 3 are directly transported from the buffer platforms 2-1 and 2-2 to the outside; and the taking-out operation is completed.

[0045] When it is necessary to put goods or boxes 3 into the multi-layer shelf 1-1 of the vertical warehouse system, Figure 1 Combine Figure 2 As shown, the goods or cargo boxes 3 enter the cache platforms 2-1 and 2-2 from the outside, and the cache platforms 2-1 and 2-2 move with the goods or cargo boxes 3 placed thereon to the height of the designated shelf. The shuttle 1-3 moves to the first position 1-2a of the shuttle lane or moves to the shuttle lifting platform 2-3, and takes the goods or cargo boxes 3 out of the cache platforms 2-1 and 2-2; the shuttle 1-3 moves with the goods or cargo boxes 3 into the lane 1-2 of the vertical warehouse system, and stores the goods or cargo boxes 3 on the multi-layer shelf 1-1 of the vertical warehouse system, completing the storage operation.

[0046] When shuttle 1-3 needs to change floors, Figure 1 Combine Figure 2 As shown, the shuttle 1-3 moves directly onto the shuttle lift tray 2-3 (as shown in FIG. Figure 2 As shown), the tray 2-3 is then lifted to the height of the designated layer by the shuttle, and finally the tray 2-3 is moved from the shuttle to the shuttle lane 1-2 of the layer to complete the layer change.

[0047] In this way, the elevator has a dual function by setting up an integrated lifting unit 2, which can realize the function of changing floors of the shuttle 1-3 and the function of transporting goods or cargo boxes 3; the shuttle lifting tray 2-3 and the cache platforms 2-1 and 2-2 are integrated in design and share a drive system to realize the function of synchronous lifting, which greatly reduces the space occupied and the difficulty of equipment installation, and reduces the investment cost of the elevator.

[0048] According to the improvement of the present invention, a storage and access system 1 is also provided. Figures 1 to 5 As shown, the storage and retrieval system 1 includes the aforementioned shuttle cargo integrated elevator, multi-layer shelf 1-1 and shuttle 1-3.

[0049] In order to increase the storage space, the access system 1 can flexibly and symmetrically set up two rows of multi-layer shelves 1-1. The two rows of multi-layer shelves 1-1 are parallel to each other and form an alley 1-2. The shuttle car 1-3 runs in the alley 1-2. Each layer of shelves includes multiple cargo spaces. Preferably, the multi-layer shelves 1-1 are modular in design and can be flexibly expanded and extended according to actual storage needs, such as lengthening the shelves along the longitudinal direction of the alley 1-2; they can also be deepened in the depth direction of the shelves, such as multi-depth shelves. The aforementioned multi-layer shelves 1-1 are well known technologies in the art, and any existing or future developed appropriate structures can be used according to the disclosure of the present invention. It is worth noting that the structure and method of the aforementioned shelves can be applicable to cargo boxes 3 of different sizes (such as cartons or turnover boxes), or directly support goods.

[0050] The aforementioned lane 1-2 has a first position 1-2a. The first position 1-2a is one end of the lane 1-2 close to the shuttle lift tray 2-3, and the lane first position 1-2a extends to the outside of the multi-layer shelf 1-1. When the shuttle 1-3 moves to the lane first position 1-2a, the shuttle 1-3 is located outside the multi-layer shelf 1-1. At this time, the shuttle 1-3 can dock with the cache platforms 2-1 and 2-2 to transfer cargo boxes between the shuttle 1-3 and the cache platforms 2-1 and 2-2. The shuttle 1-3 can move from the first position 1-2a to the shuttle lift tray 2-3. When the shuttle 1-3 moves to the lane first position 1-2a (such as Figure 1 As shown), it can directly dock with the buffer platforms 2-1 and 2-2 (without entering the lifting unit 1) to transfer cargo boxes or cargo between the shuttle 1-3 and the buffer platforms 2-1 and 2-2. Of course, when the shuttle 1-3 is located on the shuttle lift tray 2-3 (as shown), the shuttle 1-3 can directly dock with the buffer platforms 2-1 and 2-2 (without entering the lifting unit 1) to transfer cargo boxes or cargo between the shuttle 1-3 and the buffer platforms 2-1 and 2-2. Figure 2As shown, it can also dock with the buffer platforms 2-1 and 2-2 to transfer containers between the shuttle 1-3 and the buffer platforms 2-1 and 2-2. In this way, the storage and retrieval system 1 can dispatch the shuttle 1-3 to the first position 1-2a in the lane or on the shuttle lift tray 2-3 to transfer containers between the shuttle 1-3 and the buffer platforms 2-1 and 2-2 based on actual order requirements (WCS system instructions), providing flexibility and adaptability.

[0051] In certain preferred embodiments, Figure 3 、 Figure 4 Combine Figure 5 As shown, a temporary storage table is provided between the multi-layer shelf 1-1 and the cache platforms 2-1 and 2-2. In this embodiment, the number of temporary storage tables is 2; the two temporary storage tables 1-4 and 1-5 are docked with the two groups of cache platforms 2-1 and 2-2 respectively to transfer goods or cargo boxes between the temporary storage tables 1-4 and 1-5 and the cache platforms 2-1 and 2-2. Normally, the real-time conveying direction of the temporary storage table is the same as the real-time conveying direction of the cache platform. In this embodiment, the temporary storage tables 1-4 and 1-5 are roller conveyors, which can allow one or more goods or cargo boxes 3 to be placed at the same time, playing a temporary storage role. Of course, the temporary storage tables 1-4 and 1-5 can also be replaced by other types of conveying mechanisms. The aforementioned lane 1-2 also has a second position 1-2b. The second position 1-2b is located on the side of the temporary storage table, close to the aforementioned first position 1-2a, and is also located outside the multi-layer shelf 1-1. When the shuttle car 1-3 moves to the second position 1-2b of the lane (as shown in FIG. Figure 3 As shown), the shuttle 1-3 is located outside the multi-layer shelf 1-1. At this time, the shuttle 1-3 can directly dock with the temporary storage platforms 1-4 and 1-5 to transfer cargo boxes between the shuttle 1-3 and the temporary storage platforms 1-4 and 1-5.

[0052] According to the improvement of the present invention, a storage and access system 1 is also provided. Figures 1 to 5 As shown, the storage and retrieval system 1 includes the aforementioned shuttle cargo integrated elevator, multi-layer shelf 1-1 and shuttle 1-3. A lane 1-2 is provided in the multi-layer shelf 1-1; the shuttle 1-3 runs in the lane 1-2. The lane 1-2 has a first position 1-2a. The first position 1-2a is an end of the lane 1-2 close to the shuttle lifting tray 2-3. The shuttle 1-3 can move from the first position 1-2a to the shuttle lifting tray 2-3. When the shuttle 1-3 is located on the shuttle lifting tray 2-3 (as shown in FIG. Figure 2As shown), it can dock with the cache platforms 2-1 and 2-2 to transfer cargo boxes between the shuttle vehicle 1-3 and the cache platforms 2-1 and 2-2. Of course, in this facility example, in order to increase storage space, the access system 1 can also flexibly and symmetrically set up two rows of multi-layer shelves 1-1. Each layer of shelf includes multiple cargo locations. In order to improve the adaptability and versatility of the access system 1, the access system 1 can also be provided with temporary storage tables 1-4 and 1-5. The functions of the temporary storage tables 1-4 and 1-5 are the same as those described above and will not be repeated here.

[0053] The working principle of the access system 1 of the preferred embodiment proposed by the present invention is now described in detail:

[0054] When it is necessary to take out goods or cargo boxes 3, the shuttle car 1-3 takes out the goods or cargo boxes 3 from the multi-layer shelf 1-1 of the vertical warehouse system and moves to the first position 1-2a of the shuttle car aisle or moves to the shuttle car lifting platform 2-3; the shuttle car 1-3 transfers the goods or cargo boxes to the buffer platforms 2-1 and 2-2 of the elevator; the buffer platforms 2-1 and 2-2 drive the goods or cargo boxes 3 to move downward; the goods or cargo boxes 3 are directly transported from the buffer platforms 2-1 and 2-2 to the outside; and the taking-out operation is completed. In some embodiments with temporary storage tables 1-4 and 1-5, there is another implementation method, in which the shuttle car 1-3 takes out the goods or cargo boxes 3 from the multi-layer shelf 1-1 of the vertical storage system and moves to the second position 1-2b of the shuttle car aisle. The shuttle car 1-3 transfers the goods or cargo boxes to the temporary storage tables 1-4 and 1-5; the temporary storage tables 1-4 and 1-5 transfer the goods or cargo boxes to the cache platforms 2-1 and 2-2 of the elevator, and the cache platforms 2-1 and 2-2 drive the goods or cargo boxes 3 to move downward; the goods or cargo boxes 3 are directly transported from the cache platforms 2-1 and 2-2 to the outside to complete the removal operation.

[0055] When goods or cargo boxes 3 need to be stored in the vertical warehouse system, the goods or cargo boxes 3 enter the cache platforms 2-1 and 2-2 from the outside, and the cache platforms 2-1 and 2-2 move with the goods or cargo boxes 3 placed thereon to the height of the designated shelf. The shuttle 1-3 moves to the first position 1-2a of the shuttle lane or moves to the shuttle lifting platform 2-3, and takes the goods or cargo boxes 3 out of the cache platforms 2-1 and 2-2; the shuttle 1-3 moves with the goods or cargo boxes 3 into the vertical warehouse system and stores the goods or cargo boxes 3 on the multi-layer shelf 1-1 of the vertical warehouse system. In some embodiments with temporary storage tables 1-4 and 1-5, there is another implementation method, in which goods or cargo boxes 3 enter the cache platforms 2-1 and 2-2 from the outside, and the cache platforms 2-1 and 2-2 move with the goods or cargo boxes 3 placed thereon to the height of the designated layer of shelves, and the goods or cargo boxes 3 are transferred from the cache platforms 2-1 and 2-2 to the temporary storage tables 1-4 and 1-5, and the shuttle car 1-3 moves to the second position 1-2b of the shuttle car lane; and takes the goods or cargo boxes 3 out of the temporary storage tables 1-4 and 1-5; the shuttle car 1-3 moves with the goods or cargo boxes 3 into the vertical warehouse system, and stores the goods or cargo boxes 3 on the multi-layer shelves 1-1 of the vertical warehouse system, completing the storage operation.

[0056] When the shuttle 1-3 needs to change layers, the shuttle 1-3 moves directly to the shuttle lifting tray 2-3, then follows the shuttle lifting tray 2-3 to rise and fall to the height of the designated layer, and finally moves from the shuttle lifting tray 2-3 to the shuttle lane 1-2 to complete the layer change.

[0057] In this way, the storage and retrieval system 1 can realize the transfer of goods between the shuttle car 1-3 and the cache platforms 2-1 and 2-2, and the transfer of goods between the shuttle car 1-3 and the shelf temporary storage platforms 1-4 and 1-5, and the transfer of goods between the temporary storage platforms 1-4 and 1-5 and the cache platforms 2-1 and 2-2 through the ingenious design of the elevator and the ingenious layout of the shelves, the shuttle car lanes 1-2, and the temporary storage platforms 1-4 and 1-5. The goods transfer method can be adjusted in real time according to actual needs, is flexible and adaptable, and greatly reduces the investment cost of the entire storage and retrieval system while ensuring high storage and retrieval efficiency. The cost of the entire storage and retrieval system is about 40% of the storage and retrieval system of the same scale in the existing technology (vertical warehouse + shuttle car + shuttle car elevator + 2 cargo elevators); and the storage and retrieval efficiency can reach the efficiency of the storage and retrieval system in the existing technology (vertical warehouse + shuttle car + shuttle car elevator + 2 cargo elevators), which brings greater economic benefits and is also conducive to the wider promotion and application of the storage and retrieval system (integrated elevator + shuttle car + multi-layer shelf) proposed by the present invention.

[0058] According to the improvement of the present invention, a storage integrated system is also proposed. Figure 6 Combine Figure 8 As shown, the equipment includes the aforementioned storage and retrieval system 1, and a receiving station 6. The receiving station 6 can be docked with the cache platforms 2-1 and 2-2 of the shuttle cargo integrated elevator to transfer cargo boxes between the receiving station 6 and the cache platforms 2-1 and 2-2. In this way, the goods or cargo boxes 3 are directly stored in the warehouse from the receiving station 6 (the goods or cargo boxes 3 are transferred from the receiving station 6 to the cache platforms 2-1 and 2-2, and the cache platforms 2-1 and 2-2 are lifted and moved with the goods or cargo boxes 3 placed thereon to the shelf height of the designated layer, and the shuttle 1-3 performs subsequent goods or cargo box 3 retrieval and storage operations; the specific operation process is the same as described above and will not be repeated here.) Of course, in some embodiments, the integrated warehousing and storage system may also be provided with temporary storage platforms 1-4 and 1-5. If the goods or cargo boxes 3 are first transferred from the cache platforms 2-1 and 2-2 to the temporary storage platforms 1-

[0059] 4, 1-5, the shuttle 1-3 performs the taking-out operation, that is, the shuttle 1-3 directly takes out the goods or the cargo box 3 from the temporary storage table 1-4, 1-5); there is no need to set up a complex input line for receiving goods, which reduces costs, saves space, and simplifies the receiving operation process.

[0060] According to the improvement of the present invention, a storage and sorting integrated system is also proposed, such as Figure 7 Combine Figure 9As shown, the integrated storage, retrieval and sorting system includes the aforementioned storage and retrieval system 1 and at least one picking station 4. The picking station 4 has two delivery entrances 4-1 and 4-2. The two delivery entrances 4-1 and 4-2 are respectively arranged on both sides of the picking station body. The two delivery entrances 4-1 and 4-2 are directly connected to the two groups of buffer platforms 2-1 and 2-2 respectively to transfer cargo boxes between the buffer platforms 2-1 and 2-2 and the picking station 4. Each integrated elevator corresponds to at least one picking station 4. When the goods or cargo boxes 3 need to be sorted out of the warehouse, the shuttle car 1-3 takes the cargo box 3 from the multi-layer shelf 1-1, moves along the aisle 1-2 to the first position 1-2a of the aisle, the second position or the shuttle car lifting platform 2-3; and places the goods or cargo boxes 3 on the cache platform 2-1, 2-2 or the temporary storage platform 1-4, 1-5 (in some embodiments, if the goods or cargo boxes 3 are placed on the temporary storage platform 1-4, 1-5, the goods or cargo boxes 3 are transferred from the temporary storage platform 1-4, 1-5 to the cache platform 2-1, 2-2); the cache platform 2-1, 2-2 drives the goods or cargo boxes 37 to move downward; the goods or cargo boxes 3 are directly transported from the cache platform 2-1, 2-2 to the picking station, and the operator or robot completes the picking of the goods or cargo boxes 3 at the picking station. When the goods or boxes 3 need to be returned to the warehouse, the picked goods or boxes 3 are directly transported from the picking station 4 to the buffer platforms 2-1 and 2-2; the buffer platforms 2-1 and 2-2 drive the goods or boxes 3 to move upward; the shuttle 1-3 takes the goods or boxes 3 out of the buffer platforms 2-1 and 2-2 (in some embodiments, if the goods or boxes 3 are first transferred from the buffer platforms 2-1 and 2-2 to the temporary storage platforms 1-4 and 1-5, the shuttle 1-3 directly takes the goods or boxes 3 out of the temporary storage platforms 1-4 and 1-5); the shuttle 1-3 stores the goods or boxes 3 on the multi-layer shelf 1-1. In this way, there is no need to set up a complex conveyor line between the integrated elevator and the picking station 4, which greatly improves the efficiency of outbound storage, sorting, and return storage, saves space, and reduces costs.

[0061] According to the improvements of the present invention, an integrated storage, sorting and packaging system is also proposed, which includes the aforementioned integrated storage, retrieval and sorting system, as well as other equipment. The aforementioned other equipment includes at least one of a receiving station 6 and a packaging station 5. The receiving station 6 can be docked with the buffer platforms 2-1 and 2-2 of the shuttle vehicle cargo integrated elevator to transfer cargo boxes between the receiving station 6 and the buffer platforms 2-1 and 2-2. The packaging station 5 is docked with the picking station 4 to package the sorted goods. In this embodiment, the functions of the receiving station 6 and the picking station 4 are the same as those described above and will not be repeated here.

[0062] In this way, the aforementioned integrated system (several types) proposed by the present invention, its storage and retrieval system 1, integrated elevator, picking station 4, receiving station 6, and packaging station 5 adopt an integrated design as a whole, forming an integrated device. In addition to greatly reducing the investment cost, it also saves the space usage cost occupied by the complex conveyor line in the existing technology; improves the efficiency of warehousing, sorting, and packaging, and simplifies the warehousing, sorting, and packaging processes.

[0063] While the present invention has been disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
