Abstract

Official abstract text for this publication.

A workpiece transfer system including a robot that transfers a workpiece taken out of a furnace to a press forging device, a temperature measuring device that measures a temperature distribution of the workpiece being transferred by the robot, and a heating device that is capable of locally heating the workpiece in a low temperature region of the temperature distribution measured by the temperature measuring device.

First claim

Opening claim text (preview).

The invention claimed is: 1. A workpiece transfer system comprising: a robot that transfers a workpiece taken out of a furnace to a press forging device; a camera that has a view field range including a path where the workpiece is transferred by the robot and that acquires an image of the view field range; a thermometer that measures a temperature distribution of the view field range; a controller that stores a target temperature distribution of the workpiece; and a heating device, wherein the controller detects, while the workpiece is transferred by the robot, a position of the workpiece based on the image acquired by the camera and compares the temperature distribution measured by the thermometer with the stored target temperature distribution so as to sequentially determine a low temperature region of the workpiece, and the heating device heats the determined low temperature region each time the low temperature region is determined by the controller. 2. The workpiece transfer system according to claim 1 , wherein the controller corrects the stored target temperature distribution based on quality information of moldability of the workpiece in the press forging device and compares the temperature distribution measured by the thermometer with the corrected target temperature distribution. 3. The workpiece transfer system according to claim 1 , wherein the heating device comprises a scanner and heats the determined low temperature region by scanning laser light over the determined low temperature region. 4. The workpiece transfer system according to claim 2 , wherein the heating device comprises a scanner and heats the determined low temperature region by scanning laser light over the determined low temperature region. 5. The workpiece transfer system according to claim 4 , wherein, the controller calculates a difference between a temperature of the determined low temperature region and a temperature of a region corresponding to the determined low temperature region in the corrected target temperature distribution, and the heating device adjusts intensity of the laser light according to the calculated difference. 6. The workpiece transfer system according to claim 3 , wherein, the controller calculates a difference between a temperature of the determined low temperature region and a temperature of a region corresponding to the determined low temperature region in the stored target temperature distribution, and the heating device adjusts intensity of the laser light according to the calculated difference.
