Automatic adjusting device and method for pallet fork distance of forklift-type automated guided vehicle (AGV)

Abstract

The invention provides an automatic adjusting device and method for the pallet fork distance of a forklift-type automated guided vehicle (AGV). The automatic adjusting device for the pallet fork distance of the forklift-type AGV comprises a controller, a driving motor, a transmission structure and a distance measuring sensor connected with the controller, wherein the controller, the driving motor,the transmission structure and the distance measuring sensor are connected sequentially; and the forklift-type AGV is provided with two pallet forks arranged side by side, the transmission structureis connected with the pallet forks, after controlling the pallet forks to enter pallet fork holes of a pallet in place, the controller controls the driving motor to operate, the driving motor drives the transmission structure to drive the two pallet forks to move oppositely and expand outwards, the distances between the pallet forks and the inner walls of the pallet fork holes of the pallet are measured by the distance measuring sensor and sent to the controller, and when the controller judges that the distances between the pallet forks and the inner walls of the pallet fork holes of the pallet are each less than or equal to the first length, the driving motor is controlled to stop operating. The same forklift-type AGV can be suitable for pallets with different sizes simultaneously, thus the cost of a user is lowered, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of transportation equipment, in particular to a forklift type AGV trolley. Background technique [0002] AGV car, the full name of Automated Guided Vehicle car, can automatically navigate and deliver goods to the destination. It is generally used in logistics systems or factories. When transporting goods, the goods are placed on a pallet with fork holes, and the fork of the forklift AGV is inserted into the fork holes of the pallet and then rises and falls to pick and place the goods. The forklift AGV often encounters pallets of different sizes during use, and the distance between the fork holes on the pallets of different sizes is also different, while the distance between the two forks of the forklift AGV is fixed. Therefore, when facing a relatively wide pallet, the position where the fork is inserted is not the fork hole, but the hollow part between the two fork holes is so prone to instability of the center of g...

AI Technical Summary

Problems solved by technology

If the customer has goods of different specifications and widths at the same time and needs pallets of different specifications and widths, even if the weight of each goods is similar and only one forklift AGV is needed, it is also necessary to be equipped with multiple specifications and different fork spacings. Forklift AGV can meet the work needs
