Description

Technical Field

[0001] The present invention belongs to the technical field of logistics disassembly and sorting, and in particular relates to a three-in-one elevator used in a multi-storey vertical warehouse. Background Art

[0002] With the development of technology, the promotion of material technology and the increasingly close connection between warehousing logistics and sorting systems and production, many factories require unmanned seamless connection between the end of production and warehousing and sorting logistics, integrating production, warehousing and sorting into a complete system. New technologies and concepts in various aspects have been rapidly changing and growing, breaking through the constraints of existing logistics planning.

[0003] The logistics picking operation is the most time-consuming, complex and technically demanding part of the warehouse, and has become a bottleneck affecting logistics costs and operating rates. With the rapid development of related industries, massive SKUs and order fragmentation are becoming increasingly evident. With rising labor costs, various "goods-to-person" solutions have emerged. Among them, multi-pass warehousing, which has the outstanding advantages of dense storage, fast access and flexible configuration, can greatly improve space utilization and logistics efficiency, save manpower, and is therefore increasingly favored by companies.

[0004] However, in the prior art, multi-pass warehousing mostly relies on shuttle cars in conjunction with traditional lifting equipment to travel back and forth between the multi-story warehouse and the ground. In actual operation, the shuttle car needs to reach the horizontal surface where the goods are stored in the multi-story warehouse to complete the horizontal flow of picking up or putting down materials, and then complete the vertical flow of vertical lifting through traditional lifting equipment. The shuttle car needs to participate in the entire process of material flow. Although more shuttle cars can be deployed to improve a certain flow efficiency, the transportation efficiency of traditional lifting equipment is limited and cannot significantly improve the material flow efficiency. In addition, a larger number of shuttle cars will increase the equipment investment cost. Summary of the invention

[0005] The present invention provides a three-in-one elevator for use in a multi-story vertical warehouse, aiming to solve the problem that the current material circulation process requires the full participation of shuttle vehicles, and a large number of shuttle vehicles are needed to meet the demand for circulation efficiency, which not only improves the circulation efficiency to a limited extent but also increases the overall investment cost of the equipment.

[0044] The embodiment of the present invention provides a three-in-one hoist for use in a multi-storey vertical warehouse, such as Figure 1-Figure 10 As shown, a three-in-one hoist is used in a multi-storey warehouse, comprising:

[0045] A main frame assembly 100, the main frame assembly 100 comprises an inner frame 110 and an outer frame 120, the outer frame 120 is disposed on both sides of the inner frame 110;

[0046] The layer-changing cargo platform assembly 200, the first material-side cargo platform assembly 310 and the second material-side cargo platform assembly 320, the layer-changing cargo platform assembly 200 slides on the inner frame 110, the first material-side cargo platform assembly 310 and the second material-side cargo platform assembly 320 slide on different outer frames 120 respectively, the main frame assembly 100 is provided with a first traction unit, a second traction unit and a third traction unit, the first traction unit, the second traction unit and the third traction unit generate power to respectively drive the first material-side cargo platform assembly 310, the second material-side cargo platform assembly 320 and the layer-changing cargo platform assembly 200 to move in the vertical direction;

[0047] The shuttle 510 travels back and forth between the layer-changing cargo platform assembly 200 and the multi-layer vertical warehouse. The shuttle 510 reaches the shelf layer with a specified number of layers through the layer-changing cargo platform assembly 200. When the shuttle 510 reaches the shelf layer with a specified number of layers, the materials are transferred between the shelf 610, the first material-side cargo platform assembly 310, and the second material-side cargo platform assembly 320 through the shuttle 510;

[0048] In the present application, a multi-layer vertical warehouse is composed of multiple stacked shelf layers, and two groups of parallel shelves 610 are placed on different shelf layers. The gaps between the shelves 610 constitute a corridor 620. The shuttle 510 serves as a material conveying tool on the horizontal plane of the shelf layer and arrives near the designated shelf 610 along the corridor 620; the first material side loading platform assembly 310 and the second material side loading platform assembly 320 serve as vertical transportation channels for the material flow process.
