Abstract

A glassware forming machine includes a blank mold having first and second sections and a hanger assembly configured to support the first section and permit movement of the first section towards and away from the second section. A temperature measurement system for the first section includes a thermocouple configured to be received within a recess in a wall of the first section and to generate a temperature signal indicative of a temperature of the first section. The system further includes a transmitter assembly coupled to the thermocouple and comprising a housing supported on the hanger assembly and a wireless transmitter and controller disposed within the housing. The controller is configured to receive the temperature signal and generate an output signal in response for transmission by the wireless transmitter, the output signal including data indicative of the temperature of the first section of the blank mold.

First claim

What is claimed is:

1. A glassware forming machine, comprising:
a first blank mold having first and second sections;
a first hanger assembly configured to support the first section of the blank mold and to permit movement of the first section of the blank mold towards and away from the second section of the blank mold;
a temperature measurement system for the first section of the blank mold, comprising
first thermocouple configured to be received within a recess in a wall of the first section of the blank mold and configured to generate a first temperature signal indicative of a temperature of the first section of the blank mold; and,
a first transmitter assembly coupled to the first thermocouple and comprising
a first housing supported on the first hanger assembly;
a first wireless transmitter disposed within the first housing; and,
a first controller disposed within the first housing, the first controller configured to receive the first temperature signal and generate an output signal in response for transmission by the first wireless transmitter, the output signal including data indicative of the temperature of the first section of the blank mold.

2. The glassware forming machine of claim 1 , further comprising:
a second hanger assembly configured to support the second section of the blank mold and to permit movement of the second section of the blank mold towards and away from the first section of the blank mold;
a temperature measurement system for the second section of the blank mold, comprising
a second thermocouple configured to be received within a recess in a wall of the second section of the blank mold and configured to generate a second temperature signal indicative of a temperature of the second section of the blank mold; and,
a second transmitter assembly coupled to the second thermocouple and comprising
a second housing supported on the second hanger assembly;
a second wireless transmitter disposed within the second housing; and,
a second controller disposed within the second housing, the second controller configured to receive the second temperature signal and generate an output signal in response for transmission by the second wireless transmitter, the output signal including data indicative of the temperature of the second section of the blank mold.

3. The glassware forming machine of claim 1 wherein the blank mold is disposed about a central axis and the first thermocouple has a first longitudinal end disposed within the recess in the first section of the blank mold and extending in a direction parallel to the central axis and a second longitudinal end disposed outside of the recess in the first section of the blank mold and extending in a direction away from the central axis, the second longitudinal end coupled to the first transmitter assembly.

4. The glassware forming machine of claim 1 wherein the first housing is magnetically coupled to the first hanger assembly.

5. The glassware forming machine of claim 4 wherein the first housing includes a plurality of magnets disposed between the first housing and the first hanger assembly.

6. The glassware forming machine of claim 1 wherein the temperature measurement system further includes a first receiver assembly including:
a wireless receiver configured to receive the output signal of the first transmitter assembly; and,
a controller coupled to the wireless receiver.

7. The glassware following machine of claim 6 wherein the first wireless transmitter comprises a first wireless transceiver, the wireless receiver comprises a second wireless transceiver and the controller of the first receiver assembly is configured to generate a sampling rate command for transmission to the first controller of the first transmitter assembly through the first and second wireless transceivers.

8. The glassware forming machine of claim 6 wherein the temperature measurement system further comprises a display in communication with the first receiver assembly and configured to display the temperature of the first section of the blank mold measured by the temperature measurement system.

9. The glassware forming machine of claim 8 wherein an appearance of the temperature on the display varies responsive to a value of the temperature.

10. A glassware forming machine, comprising:
a plurality of blank molds, each of the plurality of blank molds having first and second sections;
a first hanger assembly configured to support the first sections of the plurality of blank molds and to permit movement of the first sections of the plurality of blank molds towards and away from the second sections of the plurality of blank molds;
a temperature measurement system for the first sections of the plurality of blank molds, comprising
a first plurality of thermocouples, each of the first plurality of thermocouples configured to be received within a recess in a wall of the first section of one of the plurality of blank molds and configured to generate a first temperature signal indicative of a temperature of the first section of the one blank mold; and,
a first transmitter assembly coupled to the first plurality of thermocouples and comprising
a first housing supported on the first hanger assembly;
a first wireless transmitter disposed within the first housing; and,
a first controller disposed within the first housing, the first controller configured to receive the first temperature signal from each of the first plurality of thermocouples and generate a corresponding output signal in response for transmission by the first wireless transmitter, the output signal including data indicative of the temperature of the first section of a corresponding blank mold of the plurality of blank molds.

11. The glassware forming machine of claim 10 , further comprising:
a second hanger assembly configured to support the second sections of the plurality of blank molds and to permit movement of the second sections of the plurality of blank molds towards and away from the first sections of the plurality of blank molds;
a temperature measurement system for the second sections of the plurality of blank molds, comprising
a second plurality of thermocouples, each of the second plurality of thermocouples configured to be received within a recess in a wall of the second section of one of the plurality of the blank molds and configured to generate a second temperature signal indicative of a temperature of the second section of the one blank mold; and,
a second transmitter assembly coupled to the second plurality of thermocouples and comprising
a second housing supported on the second hanger assembly;
a second wireless transmitter disposed within the second housing; and,
a second controller disposed within the second housing, the second controller configured to receive the second temperature signal from each of the second plurality of thermocouples and generate a corresponding output signal in response for transmission by the second wireless transmitter, the output signal including data indicative of the temperature of the second section of a corresponding blank mold of the plurality of blank molds.

12. The glassware forming machine of claim 10 wherein each of the plurality of blank molds is disposed about a central axis and each of the first plurality of thermocouples has a first longitudinal end disposed within the recess in the first section of a corresponding one of the plurality of blank molds and extending in a direction parallel to the central axis and a second longitudinal end disposed outside of the recess in the first section of the corresponding blank mold and extending in a direction away from the central axis, the sec
