AUTOMATED GUIDED VEHICLE

PROBLEM TO BE SOLVED: To provide an automated guided vehicle capable of stably transporting a truck.SOLUTION: In an automated guided vehicle 20 for transporting a truck 10 whose bottom face 2 has a fixed space with respect to a floor surface 1, on a vehicle body 21 lower than the top of the space, fluid pressure cylinders 22 which make upward pushing-up force act on the bottom face 2 of the truck 10 and are freely extended and contracted in a vertical direction are installed; a fluid pressure supply device is provided for supplying a fluid to the fluid pressure cylinders 22; pressure adjustment means is provided for adjusting the fluid pressure of the fluid which is supplied from the fluid pressure supply device to the fluid pressure cylinders 22; and a control board for making pushing-up force which is lower than total weight of weight of the truck 10 and weight of loads 30 loaded on the truck 10 act upward on the bottom face 2 of the truck 10 from the fluid pressure cylinders 22 by giving an instruction of a fluid pressure to the pressure adjustment means. The truck 10 is transported while keeping a state that a remaining load except for the pushing-up force from the total weight is loaded on wheels 11 of the truck 10.SELECTED DRAWING: Figure 1 【課題】台車を安定して搬送できる無人搬送車を提供する。【解決手段】床面１に対して底面２が一定のスペースを有する台車１０を搬送する無人搬送車２０において、スペースより低い車体２１に、台車１０の床面２に上向きの押上力を作用させる上下方向に伸縮自在な流体圧シリンダ２２が設置され、また、流体圧シリンダ２２に対して流体を供給する流体圧供給装置が備えられ、流体圧供給装置から流体圧シリンダ２２に供給される流体の流体圧を調整する圧力調整手段が備えられ、圧力調整手段に流体圧を指令することにより、台車１０の重量と台車１０に積載された荷物３０の重量を加えた総重量より低い押上力を流体圧シリンダ２２から台車１０の底面２に上向きに作用させる制御基板とが設けられ、台車１０の車輪１１には総重量から押上力を除いた残りの荷重が負荷する状態のまま、台車１０が搬送される。【選択図】図１
