Claims

An unmanned guided vehicle that transports workpieces by traveling through work positions preset with respect to each of a workpiece stocker for stocking workpieces and a processing cell that includes a processing machine that processes workpieces ; and a control device for controlling the operation of a transfer device having a robot mounted on the automatic guided vehicle and capable of gripping a workpiece,
a cell status acquisition unit that acquires information about the process progress status in the processing cell;
A control device , comprising: a movement control section that controls movement of the automatic guided vehicle based on information about the process progress status of the processing cell acquired by the cell status acquisition section .

Based on the information about the process progress status of the processing cell acquired by the movement control unit and the cell status acquisition unit, whether there will be room for the robot to work at the working position of the processing cell within a predetermined time from the current time. 2. The control device according to claim 1 , wherein it is configured to predict whether or not the automatic guided vehicle is moving, and to control the movement of the automatic guided vehicle based on the prediction .

a stock status recognition unit that recognizes the stock status of works in the work stocker;
a job generation unit that generates a job to be executed by the automatic guided vehicle and the robot based on the work stock status recognized by the stock status recognition unit;
When the movement control unit predicts that there is room for work based on the information about the process progress of the processing cell acquired by the cell status acquisition unit, the job generation unit generates a job related to the work. 3. The control system of claim 2, wherein the AGV is configured to initiate movement of the AGV toward the working position of the processing cell prior to the processing.

The movement control unit is configured to cause the automatic guided vehicle to wait at a predetermined position when it is predicted that there will be no room for work based on the information regarding the process progress status of the processing cell acquired by the cell status acquisition unit. 4. The control device according to claim 2 or 3, wherein:
