Abstract
Abstract A non-contact optical gauger for measuring glassware articles of manufacture at the hot end of an individual section machine. As the manufactured glassware is being conveyed away from the individual section machine, a light beam is direct across its path. An array of photo-sensitive sensors and a microprocessor based electronic system interpret the light beam interruptions as measurement data which are stored and can be displayed as desired.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
173 words
In glassware manufacturing apparatus including an individual section machine having a plurality of sections, each of said plurality of sections producing glassware articles of manufacture, and a conveyor for carrying said glassware articles of manufacture from said individual section machine to a lehr, the improvement comprising non-contact guager means positioned along said conveyor for measuring said glassware articles of manufacture while they are in transit on said conveyor from said individual section machine to said lehr, said gauger means comprising: a light-generating means; a light-detecting means comprising a plurality of detectors arranged in an array for signaling the interaction of energy from said light-generating means with said glassware articles of manufacture on said conveyor; and means for receiving the signals produced by said light-detecting means and for measuring, based on said signals, the diameter of said glassware articles of manufacture, the perpendicularity of an edge of said glassware articles of manufacture, the variation in the height of portions of said glassware articles of manufacture, and the roundness of said glassware articles of manufacture.
Claim 2
Dependent Claim
173 words
In glassware manufacturing apparatus including an individual section machine having a plurality of sections, each of said plurality of sections producing glassware articles of manufacture, and a conveyor for carrying said glassware articles of manufacture from said individual section machine to a lehr, the improvement comprising non-contact guager means positioned along said conveyor for measuring said glassware articles of manufacture while they are in transit on said conveyor from said individual section machine to said lehr, said gauger means comprising: a light-generating means; a light-detecting means comprising a plurality of detectors arranged in an array for signaling the interaction of energy from said light-generating means with said glassware articles of manufacture on said conveyor; and means for receiving the signals produced by said light-detecting means and for measuring, based on said signals, the diameter of said glassware articles of manufacture, the perpendicularity of an edge of said glassware articles of manufacture, the variation in the height of portions of said glassware articles of manufacture, and the roundness of said glassware articles of manufacture.
Claim 3
Dependent Claim
76 words
Apparatus as recited in claim 1 and further including first data storage means for storing data related to the measured dimensions of said articles of glassware being measured, second data storage means for storing data representing predefined standards for each of said measured dimensions, means for comparing the data stored in said first and second data storage means, and reject means responsive to said comparing means for rejecting defective glassware articles of manufacture from said conveyor.
Claim 4
Dependent Claim
70 words
Apparatus as recited in claim 2 wherein said comparing means includes means for assigning measurement quality values to each of the measured dimensions of said glassware articles of manufacture based on the comparison of the data within said first and second data storage means, and wherein said reject means includes means for generating a reject signal in response to the assignment of predetermined quality values to each of said dimensions.
Claim 5
Dependent Claim
31 words
Apparatus as recited in claim 1 and further including means for identifying the particular section of said individual section machine that produced each of said glassware articles of manufacture being measured.
Claim 6
Dependent Claim
49 words
Apparatus as recited in claim 1 wherein said plurality of detectors includes a first plurality of detectors aligned in a first vertical plane, a second plurality of detectors aligned in a second vertical plane, and a third pair of detectors displaced vertically and horizontally with respect to one another.
Claim 7
Dependent Claim
23 words
Apparatus as recited in claim 5 including means for moving said second plurality of detectors up and down in said second vertical plane.
Claim 8
Dependent Claim
20 words
Apparatus as recited in claim 1 and further including means for detecting infra-red radiation from said glassware articles of manufacture.
Claim 9
Dependent Claim
31 words
Apparatus as recited in claim 1 wherein said measuring means includes means for measuring the diameter of said glassware articles of manufacture at a plurality of heights relative to said conveyor.
Claim 10
Dependent Claim
112 words
Apparatus as recited in claim 1 wherein said measuring means comprises: means for sensing the transit time of a first edge of each of said glassware articles of manufacture from a first predetermined position to a second predetermined position and for generating a velocity signal proportional thereto; means for detecting the interval of time associated with the passage of said first edge of each of said glassware articles of manufacture and a second edge thereof past a third predetermined position and for generating a time interval signal proportional thereto; and means for combining said velocity and time interval signals for generating data proportional to the diameter of said glassware articles of manufacture.
Claim 11
Dependent Claim
117 words
Apparatus as recited in claim 1 wherein said measuring means comprises: means for detecting when a first point along said edge of said glassware articles of manufacture reaches a vertical plane defined by a predetermined position along the conveyor and for generating a first signal responsive thereto; means for sensing when a second point along said edge of said glassware articles of manufacture reaches said vertical plane and for generating a second signal responsive thereto; and means for measuring the interval of time between said first and second signals for generating a perpendicularity signal proportional to said time interval, said perpendicularity signal being a measure of the perpendicularity of the edge of said glassware articles of manufacture.
Claim 12
Dependent Claim
25 words
Apparatus as recited in claim 1 wherein said measuring means comprises means for detecting the maximum and minimum height of said glassware articles of manufacture.
Claim 13
Dependent Claim
43 words
Apparatus as recited in claim 1 wherein said measuring means includes means for measuring the diameter of said glassware articles of manufacture at a plurality of different angles around said glassware articles of manufacture, and means for comparing said plurality of diameter measurements.
Claim 14
Dependent Claim
40 words
Apparatus as recited in claim 12 wherein said means for measuring the diameter of said glassware articles of manufacture at a plurality of different angles includes mirror means for providing a plurality of views of said glassware articles of manufacture.
