Gob inspection system for glass product

摘要

The problem is solved by generating a gob image A by capturing, with a line scanning camera, an image of a falling gob that has been cut off at an orifice; generating an image B by binarizing the gob image A with a boundary value that turns a general part of the gob black and turns a peripheral lustrous portion and a defect of the gob white; generating an image C by binarizing the gob image A with a boundary value that turns the entire gob white and turns a background black and inverting the black and white; generating an image D by combining the image B and the image C together; setting a region located a given number of pixels inside an outer edge of the black area of the image D as an inspection region; and inspecting the inspection region of the gob image A to determine whether the gob is good.

主权项

1. A gob inspection system comprising:
a line scanning camera configured to scan, in a horizontal direction, a falling gob that has been cut off at an orifice; and processing means for processing data from the line scanning camera, wherein the processing means generates a gob image A by arranging lines of the data sequentially in a vertical direction; generates an image B by binarizing the gob image A with a boundary value that turns a general part of the gob black and turns a peripheral lustrous portion and a defect of the gob white; generates an image C by binarizing the gob image A with a boundary value that turns the entire gob white and turns a background black and inverting the black and white; generates an image D by combining the image B and the image C together; sets a region located a given number of pixels inside an outer edge of the black area of the image D as an inspection region; and inspects the inspection region of the gob image A to determine whether the gob is good.
