Description

Technical Field

[0001] The present invention is applied to the storage and retrieval of palletized goods in a warehouse, belongs to the field of automated warehousing, and particularly relates to a DS-PPS pallet-type intensive storage goods-to-person system. Background Art

[0002] In the field of automated warehousing for the storage and retrieval of pallets of goods in warehouses, the existing technologies mainly include the following methods: AS / RS (three-dimensional warehouse); gravity racks; shuttle racks; traditional high-level racks; AS / RS-stacker + conveyor; gravity racks-moving on rollers by self-weight + high-level forklifts; shuttle racks-shuttles + high-level forklifts or lifts; traditional high-level racks-high-level forklifts; The existing technologies have the following disadvantages: 1) AS / RS (three-dimensional warehouse): high price, high requirements for ground weight, slow construction, need to lay foundations and start construction from underground, strict requirements for pallets, aisles, and waste of space. 2) Gravity racks: driven by the weight and inclination angle of the goods to drive the unpowered rollers to roll, strict requirements for goods and pallets, slow access speed, follow first-in-first-out, and high price. 3) Shuttle racks: rely on shuttles and high forks to store and retrieve goods, must be first-in-first-out or first-in-last-out. The risk of fire is high when the shuttle is operated in the warehouse with electricity. The construction, operation and maintenance costs are high. 4) Traditional high-rise shelves: Passages must be reserved between shelves for high-rise forklifts to pick up goods, which wastes space; storage and retrieval must be done by personnel, which has a high safety risk. There is a high risk of goods falling. Summary of the invention

[0004] WMS-Warehouse Management System collects operation data information according to WCS-Equipment Control System to record, monitor and intelligently manage functions. It is mainly divided into barcode management system, cargo attribute recording system, storage location allocation command system and inventory information processing system.

[0005] WCS-Equipment Control System is located in the middle layer between WMS and logistics equipment. It is responsible for coordinating and scheduling various logistics equipment at the bottom layer so that the bottom logistics equipment can execute the business process of the warehousing system. This process is completely executed according to the process pre-set by the program.

[0006] PLC, as the programmable controller of the underlying device, is mainly responsible for completing the lateral movement, picking and inventorying actions of the RGV robot according to the command information issued by WCS. At the same time, it is connected to the BCR / RFID-identification module through the free communication port on the PLC to receive and read the barcode information, and upload the operating status and collection information to the WCS server through industrial WIFI wireless communication.

[0007] The above-mentioned DS-PPS pallet-type dense storage goods-to-person system, among which: dense storage is achieved, the forklift channel is changed into a storage area, and the storage capacity is increased by 3 times.

[0008] The above-mentioned DS-PPS pallet-type dense storage goods-to-person system, in which: the goods are delivered to the operator through the goods-to-person RGV track and the access and movement of the RGV robot.

[0009] The above-mentioned DS-PPS pallet-type intensive storage goods-to-person system, in which: automatic storage and retrieval and automatic walking are realized through the RGV robot, and multiple machines work in coordination.

[0010] The above-mentioned DS-PPS pallet-type dense storage goods-to-person system, wherein: the goods are stored by a storage chassis.

[0011] Compared with the prior art, the present invention has the following beneficial effects: the storage capacity is increased three times compared with the traditional warehouse; the operation of high-level forklifts is eliminated, reducing enterprise costs; the operation efficiency is improved because the automatic storage and retrieval technology is used, and the goods flow faster; the requirements for the construction environment are reduced, and there is no need to build from the underground like AS / RS. The new technology is built directly from the ground without damaging the warehouse and factory buildings. BRIEF DESCRIPTION OF THE DRAWINGS
