Problems solved by technology

[0004] However, the existing AGV positioning and parking technologies often rely on a single control method for terminal parking control, and this single control method has many interference or uncertain factors, such as the mechanical body structure of the AGV car, the car's Kinematic control, sensor accuracy limitation, operating environment, etc. In this case, AGV cannot effectively achieve the above three control quantities to meet the requirements of docking accuracy

Embodiment 1

[0033] Example 1, such as figure 1 and figure 2 As shown: it includes an AGV trolley. The trolley is structurally the same as the existing trolley. It also includes a transmission walking structure, such as a walking wheel, including a leg 11 and a fork for picking up goods. The fork has a lifting device, which can be lifted and lowered in the vertical direction to adjust its height position.

[0034] On the basis of the existing structure, it is necessary to install sensor components on the car body 1 of the AGV trolley. Specifically, there are at least three sensor components, which are two distance sensors 32 and one position detection sensor 31 respectively. Two of the distance sensors 32 can be mounted on the legs 11 .

[0035] Correspondingly, this technical solution needs to deploy the freight environment. There are shelves in the storage environment, pallets are stacked on the shelves, goods are placed on the pallets, and there are gaps in the pallets. The forks of ...

Embodiment 2

[0043]Embodiment 2 is different from Embodiment 1 in that the distance sensor 32 is installed on the pallet fork. When installed on the pallet fork, since the pallet fork is different from the truck legs 11, there is lifting during the stacking process. Therefore, in order to cooperate with the distance sensor 32 , corresponding baffles 41 must be provided at different height positions.

Abstract

The invention relates to the field of logistics automation, in particular to a high-precision parking AGV vehicle fork-taking device and a parking method thereof. The following technical scheme is adopted: the high-precision parking AGV vehicle fork-taking device comprises an AGV trolley and an auxiliary positioning part, wherein the AGV trolley comprises a trolley body and an induction componentmounted on the trolley body; the trolley body comprises trolley legs; a traveling wheel component is mounted on each trolley leg; a transverse mechanism capable of moving transversely is arranged on the trolley body; forks are connected to the transverse mechanism; and the induction component comprises at least two distance sensors for distance detection and a position detection sensor mounted onthe transverse mechanism. The invention aims to provide the high-precision parking AGV vehicle fork-taking device and the parking method thereof, and by virtue of the distance sensors, the position detection sensor and the transverse mechanism, the position control accuracy of three controlled quantities of the trolley is effectively improved.

Description

technical field [0001] The invention relates to the field of logistics automation, in particular to an AGV vehicle fork picking device with high precision parking and a parking method thereof. Background technique [0002] AGV, or automatic guided vehicle, refers to a transport vehicle equipped with an automatic guidance device that can travel along a prescribed guidance path. AGV has a wide range of uses, and can replace manual tasks such as stacking, unstacking, and handling in the storage environment. In the work of AGV, especially in the work of fork-type AGV, the precision of guidance and positioning is high. When the AGV is not positioned correctly, the protruding fork will not be able to pick up the specified goods on the one hand. On the other hand, there may be interference and collision with shelves or pallets, which not only reduces work efficiency, but also increases a great potential safety hazard. [0003] Specifically, the improvement of the positioning accu...
