System for adjusting position of glass plates

A method for adjusting position of glass plates by a system, said system comprising:

• a chain for conveying glass plates into a bending furnace, said chain having (a) alternate links, (b) connecting pins for holding the alternate links together, (c) extension pins extending from some of the connecting pins toward the corresponding glass plates;
• supporting members fixed to the extension pins, for supporting the glass plates and for guiding the glass plates into the bending furnace;
• a first image sensor unit for imaging actual positions of the extension pins;
• a processor for computing a difference between the actual position of the extension pin and a reference position of the extension pin;
• and
• a display device for displaying a command to adjust position of the extension pin, based on the difference, to make the extension pin take the reference position, thereby adjusting position of the glass plates, said method comprising the steps of:
• (a) imaging the actual positions of the extension pins by the first image sensor;
• (b) computing the difference between the actual position of the extension pin and the reference position of the extension pin;
• and
• (c) displaying on the display device a command to adjust position of the extension pin, based on the difference, to make the extension pin take the reference position, thereby adjusting position of the glass plates.
