Description

Technical Field

[0001] This invention relates to the field of warehousing and logistics technology, specifically to a multi-level automated warehouse intelligent warehousing and logistics system. Background Technology

[0002] Intelligent warehousing and logistics systems are modern logistics solutions that comprehensively utilize advanced technologies such as the Internet of Things (IoT), artificial intelligence (AI), automated equipment, and digital twins to achieve automated warehousing operations, digitalized management, and intelligent decision-making. Intelligent warehousing has evolved through three stages: mechanization, automation, and intelligence. Early forklifts and warehouses solved material storage problems, automated storage and retrieval systems (AS / RS) enabled unmanned storage and retrieval operations, and in recent years, the maturity of AI technology has driven the evolution of warehouse management systems (iWMS), achieving a qualitative leap from "functional intelligence" to "cross-supply chain integration." With the continuous expansion of industrial production scale, enterprises' demand for material storage is increasing daily.

[0003] However, traditional warehouses use single-layer racking or floor stacking, resulting in low material storage density, making them unsuitable for small storage spaces. Furthermore, material congestion can easily occur during transport, affecting the efficiency of material entry and exit. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of existing vertical storage warehouses having a large footprint, making them unsuitable for smaller spaces, and the problems of easy congestion and low conveying efficiency during material loading and unloading.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multi-level automated storage and retrieval system (AS / RS) includes a first AS / RS and a second AS / RS connected in series. Both the first and second AS / RS have four internal layers. The first AS / RS has several first feed lines on its first and second inlet layers, and several first discharge lines on its fourth outlet layer. The second AS / RS has several second feed lines on its first and second inlet layers, and several second discharge lines on its third outlet layer. The outer ends of the first feed lines are connected by first connecting lines, and the outer ends of the second feed lines are connected by... There is a second connecting flow line. Both the first and second connecting flow lines are double-layered. The outer end of the first discharge flow line is connected to a third connecting flow line, and the outer end of the second discharge flow line is connected to a fourth connecting flow line. A main flow line is set on the outside of the first vertical silo. The main flow line is set in four layers. The first connecting flow line is connected to the first and second layers of the main flow line at the end away from the second vertical silo. The second connecting flow line is connected to the first and second layers of the main flow line at the end facing the second vertical silo. The third connecting flow line is connected to the fourth layer of the main flow line. The fourth connecting flow line is connected to the third layer of the main flow line through the discharge flow line.

[0007] Furthermore, the end of the first connecting flow line away from the main flow line is connected to a feeding flow line, and a rapid feeding mechanism is provided on the outer side of the middle of the feeding flow line. The rapid feeding mechanism is equipped with a lifting and conveying unit inside.

[0008] Furthermore, the input end of the first connecting flow line is connected to a feeding machine, and the output end of the feeding machine is provided with a first lifting mechanism.

[0009] Furthermore, a branch line is connected to the end of the main flow line away from the second vertical silo, and a pair of discharge flow lines are symmetrically connected to the two ends of the branch line.

[0010] Furthermore, a second lifting mechanism is provided in the middle of the unloading flow line.

[0011] Furthermore, a palletizer is connected to the end of the unloading flow line that is away from the branch line.

[0012] Furthermore, both the first and second vertical storage units are equipped with unloading robotic arms.

[0013] Furthermore, both the inlet and outlet of the first and second vertical storage tanks are equipped with barcode scanners.

[0014] Furthermore, the palletizer is equipped with a labeling mechanism inside.

[0015] A storage method for a multi-level automated warehouse intelligent warehousing and logistics system includes the following steps:

[0016] S1. After the materials arrive, they are labeled. Materials that do not require material counting are fed through a fast feeding mechanism. Materials that require material counting are fed through a material counting machine.

[0017] S2. Materials are conveyed through streamlined feeders into the first and second vertical storage tanks via the first and second layer feed inlets, respectively.

[0018] S3. When materials enter the automated storage and retrieval system, they are scanned and assigned storage locations. Then, a material unloading robot moves the materials to the corresponding storage locations.

[0019] S4. The automated warehouse dispatches the required materials along the corresponding discharge ports according to the work order.

[0020] S5. After being conveyed through the streamlined conveyor, the outbound materials are packaged by the palletizer and then sent to the production line by manual labor or AGV carts.

[0021] S6. Leftover materials after use on the production line are returned to the warehouse.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. The present invention provides a multi-level automated storage and warehousing system, which connects the first and second automated storage units in series, and combines them with a four-layer structure of the main flow line and a two-layer structure of the connecting flow lines of the first and second units, so that the two automated storage units share a common main conveying flow line. At the same time, by setting the discharge layers of the two automated storage units differently, the crossover of the inlet and outlet flow lines in the vertical direction is avoided. This system can maximize the storage capacity of the automated storage units within a limited floor area.

[0024] 2. The multi-level automated storage and retrieval system of the present invention separates the feeding and discharging of materials in vertical space by setting the feeding ends of the two automated storage units on the first and second floors, and the discharging ends on the third and fourth floors respectively. With the design of the third connecting flow line connecting to the main flow line on the fourth floor and the fourth connecting flow line connecting to the main flow line on the third floor, the material entering and leaving the warehouse can be carried out simultaneously on different floors without interference, reducing congestion during material entry and exit, thereby saving space while improving material conveying efficiency and overall warehousing operation efficiency.

[0030] 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.

[0031] Please see Figures 1-4 This embodiment of a multi-level automated storage and retrieval system includes a first automated storage and retrieval system 1 and a second automated storage and retrieval system 2 connected in series. Both the first and second automated storage and retrieval systems 1 and 2 have four internal layers. The first and second layers of the first automated storage and retrieval system 1 have several first feeding lines 3, and the fourth layer of the first automated storage and retrieval system 1 has several first discharging lines 8. The first and second layers of the second automated storage and retrieval system 2 have several second feeding lines 20, and the third layer of the second automated storage and retrieval system 2 has several second discharging lines 10. The outer ends of the first feeding lines 3 are connected by first connecting lines 18, and the outer ends of the second feeding lines 20 are connected by second connecting lines 10. The first connecting flow line 19, the first connecting flow line 18 and the second connecting flow line 19 are both double-layered. The outer end of the first discharge flow line 8 is connected to the third connecting flow line 9. The outer end of the second discharge flow line 10 is connected to the fourth connecting flow line 11. The outer side of the first vertical silo 1 is provided with a main flow line 12, which is four-layered. The first connecting flow line 18 is connected to the first and second layers of the main flow line 12 at the end away from the second vertical silo 2. The second connecting flow line 19 is connected to the first and second layers of the main flow line 12 at the end facing the second vertical silo 2. The third connecting flow line 9 is connected to the fourth layer of the main flow line 12. The fourth connecting flow line 11 is connected to the third layer of the main flow line 12 through the discharge flow line 13. When materials enter the warehouse, a portion of the materials are transported along the first feed line 3 to the first vertical storage silo 1 via the first connecting flow line 18 for storage. The excess materials are transported along the first and second layers of the main flow line 12 to the second connecting flow line 19, and then through the second feed line 20 to the interior of the second vertical storage silo 2 for storage. When materials leave the warehouse, the materials in the first vertical storage silo 1 flow out along the first discharge flow line 8, then through the third connecting flow line 9 to the fourth layer of the main flow line 12, and finally out through the fourth layer of the main flow line 12 for exit. The materials in the second vertical storage silo 2 flow out through the second discharge flow line 10, then through the fourth connecting flow line 11 to the exit flow line 13, and finally out through the third layer of the main flow line 12 for exit. Through the above steps, the storage capacity of the vertical storage silo can be maximized within a limited floor area, and material entry and exit can be carried out simultaneously on different layers without interference, reducing congestion during material entry and exit, thereby saving space while improving material conveying efficiency and overall warehousing operation efficiency.

[0032] The first connecting flow line 18 is connected to a feeding flow line 4 at the end furthest from the main flow line 12. A rapid feeding mechanism 5 is provided on the outer side of the middle of the feeding flow line 4, and a lifting and conveying unit is provided inside the rapid feeding mechanism 5. The input end of the first connecting flow line 18 is connected to a counting machine 6, and the output end of the counting machine 6 is provided with a first lifting mechanism 7. Materials that do not require counting are fed through the rapid feeding mechanism 5, and the lifting and conveying unit lifts the materials to the corresponding layer height before sending them into the feeding flow line 4. Materials that require counting are first counted by the counting machine 6, and then lifted to the corresponding layer height by the first lifting mechanism 7 before being sent into the feeding flow line 4, so that the materials are conveyed along the feeding flow line 4 to the first connecting flow line 18. Through the above steps, the differentiated feeding needs of different materials can be met.

[0033] A branch line 14 is connected to the end of the main flow line 12 away from the second vertical storage 2. A pair of unloading flow lines 15 are symmetrically connected to both ends of the branch line 14. A second lifting mechanism 16 is set in the middle of the unloading flow line 15. A palletizer 17 is connected to the end of the unloading flow line 15 away from the branch line 14. Outbound materials are conveyed to the branch line 14 via the main flow line 12. The branch line 14 symmetrically distributes the materials to the pair of unloading flow lines 15. The materials are conveyed to the second lifting mechanism 16 on the unloading flow line 15. The second lifting mechanism 16 conveys the materials to the required stacking height by changing the layers. The stacked materials are then conveyed to the palletizer 17, which automatically stacks and packages the materials. This achieves automatic stacking of outbound materials and improves the efficiency of outbound packaging.

[0034] Both the first vertical storage unit 1 and the second vertical storage unit 2 are equipped with unloading robots. After the material enters the vertical storage unit, the unloading robot will move the material from the inlet to the corresponding storage location, or move the material out of the storage unit from the storage location to the outlet.

[0035] Both the first vertical storage unit (1) and the second vertical storage unit (2) are equipped with barcode scanners at their inlet and outlet. When materials enter or leave the storage units, the barcode scanners automatically scan the material labels, and the system allocates storage locations or records outbound information based on the scanning results.

[0036] The palletizer 17 is equipped with a labeling mechanism. While the palletizer 17 is packing materials, the labeling mechanism automatically affixes material labels for easy identification and traceability later.

[0037] A storage method for a multi-level automated warehouse intelligent warehousing and logistics system includes the following steps:

[0038] S1. After the materials arrive, they are labeled. Materials that do not require material counting are fed through the fast feeding mechanism 5. Materials that require material counting are fed through the material counting machine 6.

[0039] S2. The materials are conveyed through streamlines and enter the first vertical storage silo 1 and the second vertical storage silo 2 through the first and second layer feed inlets respectively;

[0040] S3. When materials enter the automated storage and retrieval system, they are scanned and assigned storage locations. Then, a material unloading robot moves the materials to the corresponding storage locations.

[0041] S4. The automated warehouse dispatches the required materials along the corresponding discharge ports according to the work order.

[0042] S5. After being conveyed through the streamlined transport, the outbound materials are packaged by the palletizer 17 and sent to the production line by manual labor or AGV carts.

[0043] S6. Leftover materials after use on the production line are returned to the warehouse.

[0044] Working principle: When materials enter the warehouse, a portion of the materials are transported to the first vertical storage silo 1 via the first connecting flow line 18 and the first feeding flow line 3 for storage. The excess materials are transported to the second connecting flow line 19 via the first and second layers of the main flow line 12, and then to the second vertical storage silo 2 via the second feeding flow line 20 for storage. When materials leave the warehouse, the materials in the first vertical storage silo 1 flow out along the first discharge flow line 8, then flow to the fourth layer of the main flow line 12 via the third connecting flow line 9, and finally exit through the fourth layer of the main flow line 12. The materials in the second vertical storage silo 2 flow out via the second discharge flow line 10, then are transported to the outbound flow line 13 via the fourth connecting flow line 11, and finally exit through the third layer of the main flow line 12. Through the above steps, the storage capacity of the vertical storage silo can be maximized within a limited area. Material entry and exit can be carried out simultaneously on different layers without interference, reducing congestion during material entry and exit. This saves space while improving material conveying efficiency and overall warehousing operation efficiency.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
