Workpiece transfer system

A workpiece transfer system comprising:

• a workpiece infeed device configured to feed at least one workpiece;
• a robot configured to transfer said at least one workpiece that is fed;
• a workpiece outfeed device on which said at least one workpiece transferred by the robot from the workpiece infeed device is to be placed;
• a machine learning device configured to construct a learning model used to indicate an operating condition of the robot;
• and
• a control device configured to select the operating condition of the robot by applying a condition related to said at least one workpiece and/or a condition related to the robot to the learning model and to control the robot according to the operating condition, wherein
• the machine learning device includes
• an input data obtaining unit configured to obtain, as input data, a correspondence relation between the condition related to said at least one workpiece and/or the condition related to the robot and the operating condition,
• a label obtaining unit configured to obtain, as a label, information indicating whether or not processing performance of the robot is excessive or whether or not the processing performance of the robot is insufficient, and
• a learning unit configured to perform supervised learning based on teaching data constituted by a set of the input data and the label to construct the learning model that is to be used to indicate the operating condition of the robot, and
• the control device includes
• a storage unit in which the learning model obtained from the machine learning device is stored,
• a selection unit configured to select, as the operating condition of the robot, an optimum operating condition based on the learning model, and
• an operation control unit configured to control operation of the robot according to the operating condition selected by the selection unit.
