Fork plate type carrier

Abstract

The invention discloses a fork plate type carrier which comprises a self-walking carrier body, a guide device, a laser ranging device, precision locating devices, a pallet fork device and a perpendicular lifting mechanism. The pallet fork device and the perpendicular lifting mechanism are installed on the self-walking carrier body. The pallet fork device has the functions of bidirectional transverse extending and precision locating for cargo box storing and taking. According to an external command, the self-walking carrier body automatically walks to a designated location or station under the guidance of the guide device, the laser ranging device automatically measures stop position errors of the carrier, and when the stop position errors exceed an allowable value and are within an adjustable range, the precision locating devices are started for precision locating of the carrier. After the stop position precision meets requirements, the pallet fork device conducts operation of storing and taking. The fork plate type carrier is simple in structure, small in occupied area, good in stress in the working process and free of bearing capsizing moment. The stop position precision is high, the pallet fork device can be used for taking cargos on the left and on the right, and positions of the cargos on a pallet fork can be located precisely.

Description

technical field [0001] The invention relates to an intelligent transport trolley in the technical field of intelligent storage, in particular to an intelligent access transport trolley suitable for small transport space, high parking precision requirements and high access operation precision requirements. Background technique [0002] The existing intelligent storage and retrieval trolley usually installs the fork on one side of the vehicle body. To access the goods, the goods need to be placed manually along the guide of the positioning block, so that the trolley can accurately pick and place the goods. This trolley with forks installed on one side of the car body has the following technical defects: 1. It occupies a large area, and the required transportation space becomes larger, which cannot meet the cargo transportation needs of some smaller or narrow passages. Moreover, the center of gravity of the cargo is offset from the center of gravity of the equipment. During the...

AI Technical Summary

Problems solved by technology

This kind of handling trolley with the fork installed on one side of the car body has the following technical defects: 1. It occupies a large area, and the required transportation space becomes larger, which cannot meet the cargo transportation needs of some small or narrow passages

Moreover, the center of gravity of the cargo is offset from the center of gravity of the equipment. During the process of cargo transportation, the equipment is subjected to a large overturning moment and the stability is poor.

2. The stop accuracy is not high, usually about ±10mm, and a few can reach about ±5mm

This kind of parking trolley is not only difficult to meet the cargo pick-and-place requirements with high parking precision requirements

And in the process of stopping at the station, if the stop accuracy is not punctual, it can only be returned and re-entered, thus affecting its work efficiency

3. Only one-way access to goods can be performed, and the work efficiency is low

4. When accessing the goods, the position of the goods on the fork cannot be accurately positioned, and often tilt or even get stuck
