<p>PURPOSE: To reduce the cost with a simple mechanism by forming the device of a single light source, single image pick up device, reflecting plate and a signal processor, so that attitude control of limited four directions of a workpiece of small article rectangular parallelopiped can be surely performed. CONSTITUTION: A preliminary arranged workpiece 1 is arranged in an attitude discriminating position 30 by a conveyer 9. An image is picked up by an image pick up device 7, to transmit this result to a signal processor 8, so as to decide an obverse/reverse. In the case of obverse, a right/left is further decided, to end changing an attitude with the workpiece left as it is in the case of properly providing a left side surface, and the workpiece is conveyed to the next process. In the case not proper, a position of right/left side surfaces is corrected by an attitude changer 4, to convey the workpiece to the next process. Next in the case of reverse by obverse/reverse decision, a slide type reflecting plate 5 is moved to a lower side of the workpiece 1, to pick up an image from the reflecting plate 5 processed, so as to decide a right/left. In the case of this result proper, obverse/reverse position correction is performed, to convey the workpiece to the next process. In the case of not proper, the obverse/reverse position correction is performed by an attitude changer 3, to perform right/left correction by the attitude changer 4.</p> |
