WIPO Patent Application WO/2022/091863

A1

The present invention addresses the problem of providing a conveyance device capable of reducing the frequency of stoppages.　In the present invention, a conveyance path 7 is formed by connecting a plurality of conveyance units. The conveyance units each have a drive device, which drives the conveyance unit, and an individual control device which controls the conveyance unit. The individual control devices each have a high-level control device 46 in a conveyance device that drives the conveyance unit when specific drive conditions are met. The high-level control device 46 communicates with the individual control device, and the high-level control device 46 has a state of movement monitoring means 35 for monitoring the state of movement of an actual conveyed article on the conveyance path 7. A correction operation for driving the conveyance units is carried out on the basis of a specific state of the surroundings of the conveyed article irrespective of the drive conditions if the conveyance unit, on which the conveyed article has been placed, has stopped even though the conveyed article can be moved.
