Document Type and Number:

WIPO Patent Application WO/2011/118616

Kind Code:

A1

Abstract:

Disclosed is a gob forming device that is provided with a molten glass forming mechanism (1) that has an orifice (11) on the bottom, and a cutting mechanism (2) that forms gobs (g) by cutting the molten glass formed and dangling from the orifice (11). The gob forming device is further provided with the following: a cutting position adjustment mechanism for adjusting height by changing the position of the cutting mechanism (2), a gob monitoring device (6) for three-dimensionally viewing the falling gobs (g), an image processing device (7), which determines whether or not the length (L) of the gobs (g) is appropriate by requesting the length (L) of the gobs (g) from the gob (g) spatial position data obtained by the gob monitoring device (6), and, when determined not to be appropriate, calculates the correction data in order to correct the height of the cutting mechanism (2) based on the difference between the set value and the measured value of the length (L) of the gobs, and a control device (8) for changing the position of the cutting mechanism (2) by controlling the operation of the cutting position adjustment mechanism based on the correction data.
