METHOD AND MACHINE FOR CONTROL OF MOLDING PROCESS Russian patent published in 2022 - IPC G01N23/46 

FIELD: glass production.

SUBSTANCE: invention is used for control of the molding process of glass vessels. Control of the molding process of glass vessels is carried out using an installation with several separate molding sections, in each of which at least one drop of molten glass is first shaped into a billet in at least one rough form, then it is given the final shape in at least one finishing form. Control of the molding process of glass vessels contains stages, at which: a vessel called the analyzed vessel is selected, associated with the identified rough form and the identified finishing form; the analyzed vessel is placed on a holder of the analyzed vessel of an X-ray computed tomography device; several X-ray images of the analyzed vessel are obtained using the tomography device at different projection angles; X-ray images are transmitted to a computing device; data of the position of the analyzed vessel in the finishing form in the coordinate system associated with the form is transmitted to the computing device; using the computing device, X-ray images are analyzed in order to: build a three-dimensional digital model (M) of the analyzed vessel in a virtual coordinate system based on X-ray images; determine the position of the three-dimensional digital model relatively to the position of the analyzed vessel in the coordinate system associated with the form; and the three-dimensional digital model (M) is analyzed to determine at least one indicator (A) of the quality of the analyzed vessel, associated with at least one area of the analyzed vessel, allowing one to output corrective information for at least one specified parameter of the molding process relatively to the shape of the analyzed vessel.

EFFECT: providing the possibility of quality control of glass vessels using a single machine, which allows for accurate, repetitive and fast measurements, providing largely complete information for correcting set parameters of the molding process of glass vessels at a molding installation.
