A conveyance device including a plurality of conveyance units connected to form a conveyance path,

• the plurality of conveyance units each comprising:
• a drive device driving the conveyance unit;
• and
• an individual control device controlling the conveyance unit, the individual control device allowing the drive device to drive the conveyance unit when a specific drive condition is satisfied, the individual control devices exchanging information on a destination of the object between each other to convey the object to a predetermined conveyance destination,
• the conveyance device comprising a host control device communicating with the individual control devices,
• the host control device comprising:
• a movement path estimation unit estimating a movement path of the object;
• and
• a movement situation monitoring unit monitoring a movement situation of an actual object on the conveyance path,
• wherein when a specific object is about to deviate from the movement path estimated by the movement path estimation unit, a correction operation is executed in preference to the information on the destination exchanged between the individual control devices, the correction operation guiding the object to a path estimated by the movement path estimation unit.
