Conveying-traveling-body-utilizing conveying device

A conveying-traveling-body-utilizing conveying device comprising a conveying traveling body, which includes a load bar for friction drive that is continuous across its total length, and a friction drive means, which is disposed at a travel path flank and drives the conveying traveling body to travel by a friction drive wheel in pressure contact with the load bar, with the conveying traveling body being provided with a linking means, which links longitudinally adjacent conveying traveling bodies to each other in a state where the respective load bars are made continuous to each other, the linking means being constituted of a linked part, provided at one end among respective front and rear ends of the load bar, a linking hook, provided at the other end and capable of being engaged with and disengaged from the linked part of another adjacent conveying traveling body, and an operated part provided at the linking hook, and a linking hook operating rail, acting on the operated part to switch the linking hook between an engaged orientation and a non-engaged orientation with respect to the linked part, being disposed along the travel path to a side of the conveying travel body, and

• the linking hook is pivotally supported so as to be vertically movable between a pre-engagement orientation of being separated upward from the linked part of the other adjacent conveying traveling body with respect to the engaged orientation of covering the linked part from above, and a standby orientation of being tilted to a lowering limit from the engaged orientation by an urging force, and, when the linking hook is in the standby orientation, longitudinally adjacent conveying traveling bodies are enabled to approach each other to a connected state, where the respective load bars are abutted against each other, without the linking hook in the standby orientation and the linked part of the other adjacent conveying traveling body contacting each other.
