Abstract

Test dummy for detecting at least one process variable in the manufacture of glassware of identical or similar design along a production line, comprising a base body which is adapted to the shape and/or dimension of the glassware in such a manner that it can pass through the production line instead of a glassware, at least one sensor system mounted on the base body for detecting the at least one process variable on the base body, and at least one transmission apparatus mounted on the base body for transmitting the at least one detected process variable to a digital receiving unit.

First claim

The invention claimed is:

1. A method for detecting at least one process variable in the manufacture of glassware of identical or similar design along a production line, said method comprising:
adapting at least one test dummy to the glassware with respect to shape and dimensions, wherein each of the at least one test dummy comprises:
a base body adapted to have a shape and/or dimensions of the glassware for at least one time period of movement along the production line,
at least one sensor system mounted on the base body for detecting the at least one process variable, and
at least one transmission apparatus attached to the base body for transmitting the at least one detected process variable to a digital receiving unit;
integrating the at least one test dummy into the production line in order to pass the at least one test dummy through the production line instead of glassware;
detecting the at least one process variable of the production line on or in the at least one test dummy;
transmitting the at least one detected process variable to a digital receiving unit;
analyzing the transmitted at least one process variable; and
changing one or more process conditions along the production line on the basis of the analysis by modifying the at least one process control variable during operation of the production line, wherein the at least one process control variable is selected from a group consisting of: a burner gas composition, a gas mixing ratio, a flame distance, a flame position, a distance between burner flames, an arrangement of burner flames around the glassware, and combinations thereof.

2. The method according to claim 1 , wherein the at least one test dummy passes through the production line below limit values of process conditions of the production line.

3. The method according to claim 2 , wherein the process conditions do not exceed a limit value of a surface temperature of 500° C. at least at a section of the test dummy.

4. The method according to claim 1 , wherein the test dummy partly passes through the production line, and at least one predefined portion of the production line, wherein the test dummy is integrated into the production line exclusively in the at least one predefined portion of the production line.

5. The method according claim 1 , further comprising determining a correlation between the at least one process variable detected by means of the test dummy and the at least one process variable during the manufacture of the glassware in a time portion immediately before, during or after an at least partial processing of the glassware within the at least one portion of the production line.

6. The method according to claim 1 , wherein the at least one process variable comprises surface temperature of the test dummy.

7. The method according to claim 1 , wherein the modification of the at least one process control variable comprises a minimization or maximization of an effect on the at least one process variable.

8. The method according to claim 1 , wherein the production line comprises at least one receptacle able to hold glassware or the test dummy, and a conveying apparatus for moving the at least one receptacle along the production line.
