Abstract
A system and method for coating glass gobs with a liquid-based lubricating dispersion during their drop to blank glass container molds which provides sufficient lubrication to the glass container molds without requiring swabbing of the glass container molds. The lubricating dispersion is sprayed onto hot glass gobs as they fall from the gob supply system prior to their distribution by the gob distribution system into blank molds. The lubricating dispersion coats the falling glass gobs to lubricate the glass gobs as well as the molds.
Claims29
A system for applying a lubricant to free falling hot glass gobs prior to the distribution and loading of the gobs into respective blank molds in an I.S. machine, the system comprising:
- an enclosure comprising a top surface, a bottom surface, and side walls extending between the top surface and the bottom surface, the top surface and the bottom surface having corresponding openings therein, wherein the openings in the top surface and the bottom surface are arranged and configured in the top surface and the bottom surface to allow the free falling gobs to pass freely through the openings in the enclosure without contacting the enclosure when the enclosure is mounted in the path of the free falling gobs;
- a source of a liquid-based lubricating dispersion for lubricating the gobs;
- a plurality of nozzles being mounted in or adjacent to the enclosure, each of the nozzles being arranged and configured to direct a spray of the lubricating dispersion therefrom into the enclosure and onto the free falling gobs as they pass through the enclosure to substantially completely coat the gobs with the lubricating dispersion sprayed from the nozzles;
- and
- a pump system for pumping the lubricating dispersion from the source of the lubricating dispersion to the nozzles mounted in the enclosure.
A system for applying a lubricant to free falling hot glass gobs sheared from a stream of molten glass provided from a feeder prior to the distribution and loading of the gobs into respective blank molds in an I.S. machine, wherein the I.S. machine comprises a gob supply apparatus for providing gobs and a gob distribution system that distributes the glass gobs to the blank molds, wherein the system comprises:
- an enclosure comprising a top surface, a bottom surface, and side walls extending between the top surface and the bottom surface, the top surface and the bottom surface having corresponding openings therein, wherein the enclosure is arranged and configured for installation intermediate the path of the glass gobs as they fall from the gob supply apparatus and before they enter the gob distribution system, and wherein the openings in the top surface and the bottom surface are arranged and configured in the top surface and the bottom surface to allow the free falling gobs to pass freely through the openings in the enclosure without contacting the enclosure when the enclosure is mounted in the path of the free falling gobs;
- a high pressure source of a liquid-based lubricating dispersion for lubricating the gobs, the lubricating dispersion comprising powdered synthetic or natural graphite in a water-based dispersion;
- at least four nozzles being mounted in or adjacent to the enclosure, each of the nozzles being arranged and configured to direct a spray of the lubricating dispersion therefrom from a different orientation into the enclosure and onto the free falling gobs as they pass through the enclosure to substantially completely coat the gobs with the lubricating dispersion sprayed from the nozzles;
- and
- a pump system for pumping the lubricating dispersion from the source of the lubricating dispersion to the nozzles mounted in the enclosure.
A system for applying a lubricant to free falling hot glass gobs in an I.S. machine, the system comprising:
- an enclosure comprising corresponding openings respectively located in top and bottom surfaces having side walls extending therebetween, wherein the enclosure is arranged and configured for mounting with respect to the I.S. machine such that free falling gobs pass freely through the openings in the enclosure;
- a plurality of nozzles mounted in or adjacent to the enclosure;
- and
- a pump that pumps a liquid-based lubricating dispersion for lubricating the gobs from a source of the lubricating dispersion to the nozzles;
- wherein the nozzles are each arranged and configured to direct a spray of the lubricating dispersion into the enclosure and onto the free falling gobs as they pass through the enclosure.
A method for applying a lubricant to free falling hot glass gobs sheared from a stream of molten glass provided from a feeder prior to the distribution and loading of the gobs into respective blank molds in an I.S. machine, the method comprising:
- locating an enclosure in the path of the free falling gobs, the enclosure comprising a top surface, a bottom surface, and side walls extending between the top surface and the bottom surface, the top surface and the bottom surface having corresponding openings therein, wherein the enclosure is mounted such that the free falling gobs fall through the openings in the top surface and the bottom surface without contacting the enclosure;
- pumping a liquid-based lubricating dispersion for lubricating the gobs from a source of the lubricating dispersion to a plurality of nozzles mounted in or adjacent to the enclosure with a pump system;
- and
- directing sprays of the lubricating dispersion emitted from the nozzles into the enclosure and onto falling gobs as they pass through the enclosure to substantially completely coat the gobs with the lubricating dispersion sprayed from the nozzles.
A method for applying a lubricant to free falling hot glass gobs comprising:
- providing a liquid-based lubricating dispersion for lubricating the gobs at a selected location in a path of the free falling gobs;
- and
- spraying the lubricating dispersion onto the falling gobs as they pass the selected location to substantially completely coat the gobs with the lubricating dispersion.
