Method, device and system for placing/retrieving goods by pallet stacker

Abstract

The invention discloses a goods placing and taking method, device and system for a tray piling trolley. The method comprises the steps that an upper computer obtains static three-dimensional coordinates of a position where goods need to be placed or taken; movable three-dimensional coordinates of a fork body of the piling trolley are obtained in real time; according to the opposite position relation between the static three-dimensional coordinates and the movable three-dimensional coordinates, the piling trolley is controlled to work, when the distance from the static three-dimensional coordinates to the movable three-dimensional coordinates is smaller than a preset assigned distance, it is judged that the static three-dimensional coordinates coincide with the movable three-dimensional coordinates, and the fork body is controlled to place or take the goods. Staff do not need to determine the placing / taking position through the eyes, the goods are automatically placed to the assigned position or taken from the assigned position, the speed of goods placing and taking is increased, the accuracy of goods placing and taking is improved, and labor intensity of the staff is relieved.

Description

technical field [0001] The present invention relates to the field of goods handling, in particular to a method, device and system for placing / retrieving goods by a pallet stacker. Background technique [0002] The most typical application of wireless technology in the field of positioning is the satellite-based positioning system, such as the GPS positioning system of the United States, the GLONASS positioning system of Russia, and the second-generation Beidou navigation and positioning system of China. These systems are widely used in navigation and outdoor positioning. However, the positioning accuracy of these systems in the civilian field is about 10-15 meters, which does not meet people's needs for high-precision positioning indoors or in special areas. People are not very mature in applications such as indoor positioning, short-distance positioning, and special area positioning. [0003] Indoor positioning technologies based on wireless networks mainly include UWB, Wi-...

AI Technical Summary

Problems solved by technology

No matter what kind of stacker truck, when stacking goods, the staff needs to carefully confirm the position of the goods stacking. The goods cannot be placed in the designated position at one time, and the goods must be adjusted several times before they can be placed on the shelf

In the above-mentioned stacking process, there are problems such as slow stacking speed of the staff, serious energy consumption, and low accuracy of the position of the stacked goods.
