Abstract

A transport vehicle includes a pair of top arms that extend and retract, a pair of guides disposed below the pair of top arms, an adjuster that changes a spacing between the pair of guides, a cargo placement surface disposed below the pair of guides, a clamping detector that detects whether or not the cargo is being held between the pair of guides, and a controller. The controller pulls the cargo onto the cargo placement surface, then causes the adjuster to start a positioning operation as an operation to reduce a spacing between the pair of guides, and stops the positioning operation when the clamping detector detects that the cargo is being held between the pair of guides.

Description

technical field [0001] The present invention relates to a truck for moving goods. Background technique [0002] Conventionally, for example, there are transport vehicles that receive and transport goods from shelves or conveyors. Such a transport vehicle is equipped with a transfer device for delivering goods to and from a rack or a conveyor. As a transfer method of the load of the transfer device, there is, for example, a push-pull method in which the load is pulled in and pushed out by a hook member provided on a telescopic arm. [0003] For example, Patent Document 1 discloses a transport vehicle in which loads are pulled in by an openable and closable hook-shaped member provided at the ends of a pair of telescopic left and right arms. According to this transport vehicle, the cargo is positioned by clamping the cargo with a pair of left and right arms before pulling in the cargo. Thereby, for example, it is possible to unload the cargo at the correct position during su...

Problems solved by technology

Therefore, when such a cargo is clamped by the pair of left and right arms, there is a possibility that the cargo cannot withstand deformation due to the clamping force of the pair of left and right arms.
