Title:
METHOD FOR POSITIONING A WORK IN A SPINNING MACHINE AND SPINNING MACHINE FOR PRODUCING LIGHT-ALLOY WHEELS
Document Type and Number:
WIPO Patent Application WO/1995/005907
Kind Code:
A1
Abstract:
In this invention, a design pattern (5) formed on a disc surface (4) of a work (3) is picked up as an image data by a camera (18) and compared with a predetermined design pattern data by an image processing system to calculate a deviation in rotation angle between the two patterns. Then, based on the result of the calculation the rotational positions of the work (3) and/or dies (2, 9) on a spinning machine are automatically adjusted so that the design pattern (5) on the work (3) and design patterns (6, 10) formed in the dies (2, 9) coincide with each other. This eliminates the necessity of any manual preparatory work prior to supportingly mounting the work (3) on the die to automatically mount the work (3) on the die with the two patterns positioned accurately coinciding with each other, whereby it is possible not only to remarkably improve the efficiency of the spinning process as a whole but also to restrain a risk of the work being damaged by the dies (2, 9) during the spinning process.
