Pallet-type dense storage-pallet to people system (DS-PPS)

Abstract

The invention discloses a pallet-type dense storage-pallet to people system (DS-PPS). The pallet-type DS-PPS comprises a warehouse management system (WMS) for managing properties, positions, the inputting and outputting time and the number of goods, and a warehouse control system (WCS) for receiving an instruction transmitted by the WMS and controlling a robot to store and fetch the goods. The pallet-type DS-PPS further comprises a programmable logic controller (PLC) for controlling the position and detailed actions of the robot, and a BCR / RFID-identification module for identifying, comparingwhether an assessed storing loading chassis is accurate or not and reporting the completed actions to the WMS. The BCR / RFID-identification module comprises a bar code reader and a card reader. According to the pallet-type DS-PPS, storage capacity is increased by three times compared with a traditional warehouse; high-position forklift operation is eliminated, and the enterprise cost is reduced; the operation efficiency is accelerated, an automatic storage and fetching technology is used, and thus the goods circulation speed is higher; and the requirement for the building environment is reduced.

Description

technical field [0001] The invention is applied to the storage and retrieval of palletized goods in a warehouse, belongs to the field of automatic storage, and in particular relates to a DS-PPS pallet-type intensive storage goods-to-person system. Background technique [0002] In the field of automated warehousing for the storage and retrieval of palletized goods in warehouses, there are mainly the following methods in the prior art: AS / RS (three-dimensional warehouse); gravity racks; shuttle racks; traditional high racks; AS / RS-stacks Stacker + Conveyor; Gravity Rack - moves on the roller by its own weight + high forklift; Shuttle Rack - shuttle + high forklift or lift; traditional high rack - high forklift; the following disadvantages exist in the prior art: 1 )AS / RS (three-dimensional warehouse): high price, high requirements for ground storage, slow construction, need to lay the foundation and build from the ground, strict requirements for pallets, passages, waste of spa...

[0002] In the field of automated warehousing for the storage and retrieval of palletized goods in warehouses, there are mainly the following methods in the prior art: AS / RS (three-dimensional warehouse); gravity racks; shuttle racks; traditional high racks; AS / RS-stacks Stacker + Conveyor; Gravity Rack - moves on the roller by its own weight + high forklift; Shuttle Rack - shuttle + high forklift or lift; traditional high rack - high forklift; the following disadvantages exist in the prior art: 1 )AS / RS (three-dimensional warehouse): high price, high requirements for ground storage weight, slow construction, need to lay the foundation to build from the ground, strict requirements for pallets, there are passages, waste of space

2) Gravity-type shelves: rely on the self-weight and inclination angle of the goods to drive the unpowered rollers to roll, strict requirements on goods and pallets, slow access speed, follow first-in first-out, and high prices

Higher construction, operating and maintenance costs

4) Traditional high-level shelves: channels must be reserved between shelves for high-level forklifts to pick up goods, wasting space; access must be done by personnel, and the safety risk is high

High risk of falling cargo
