Transport Vehicle

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 transporting goods. Background technique [0002] Conventionally, there has been a transport vehicle that receives and transports goods from a rack or a conveyor, for example. Such a transport vehicle is equipped with a transfer device that transfers goods to and from racks, conveyors, or the like. As a method of transferring the cargo of the transfer device, for example, there is a push-pull method in which the cargo 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 that draws in goods by means of hook-shaped members that can be opened and closed provided at the ends of a pair of arms that can be extended and contracted. According to this truck, before pulling in the goods, the left and right arms are used to clamp the goods, thereby completing the positioning of the goods. As a result, for example, the cargo can be u...

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.
