Abstract

DC60 (18/04/44) A pair of facing and opposite radiated energy sensors (20, 22) are positioned facing the immediately formed glass packaging (C) being conveyed on a two-sided conveyor (12, 14) to determine if any packaging is out of alignment. Each sensor has a fiber assembly and a precisely focused lens (24) which is focused to measure radiated energy in the cone region of the packaging no larger than 1 degree. A barrier (32) is positioned between the conveyors and in line with the opposite sensors to isolate the sensors from the radiated energy of the packaging on the distant conveyor. A pair of facing and opposite radiated energy sensors (20,22) are positioned facing the immediately formed glass packaging (C) being conveyed on a two-sided conveyor (12,14) to determine if any packaging is out of alignment. As required, each sensor has a fiber assembly and a precisely focused lens (24) which is focused to measure the energy radiated in the cone region of the packaging no larger than 1°. A barrier (32) is positioned between the conveyors and is aligned with the sensors opposite it in order to isolate the sensors from the energy radiated from the packaging on the distant conveyors.

Claims (9)

1. An apparatus for immediate inspection of finished glass packaging, consisting of a conveyor for transporting the packaging through the inspection point, a radiant energy sensor positioned at the inspection point to detect heat energy emitted by the packaging (the sensor is focused to detect heat energy in the lower cone area no larger than 1°), and a barrier positioned in line with the radiant energy sensor. The conveyor is positioned between the barrier and the sensor. The barrier is used to separate the sensor from any source of radiant energy other than the energy emitted from the packaging or the conveyor. 2. An apparatus as specified in claim 1, in which such sensor is positioned relative to the conveyor to receive thermal energy from a location within the packaging on the conveyor, slightly above the slightly rounded end of the packaging, when the packaging is in a correctly upright position. 3. The device (10) is used for immediate inspection of finished glass packaging. It consists of a first conveyor (12) to transport the packaging through the first inspection point, a second conveyor (14) to transport the packaging through the second inspection point, a first radiated energy measurement method (20) located at the first inspection point to receive heat energy emitted from the packaging on the first conveyor, and the first radiated energy sensor is focused to measure heat energy in the lower cone area no larger than 1°, and a second radiated energy measurement sensor (22) located at the second inspection point to receive heat energy emitted from the packaging on the second conveyor, and the second radiated energy sensor is focused to measure heat energy in the cone area no larger than 1°. The first and second radiated energy measurement sensors are opposite each other and are located outside the first conveyor. and the second conveyor, both of them, and the barrier (32) which is positioned between the first conveyor and the second conveyor and in line with the first radiated energy sensor and the second radiated energy sensor to prevent the first radiated energy sensor from receiving energy radiated from the packaging on the second conveyor and to prevent the second radiated energy sensor from receiving energy radiated from the packaging on the first conveyor. 4. The device as specified in claim 3, in which the first radiant energy sensor is positioned relative to the first conveyor to receive heat energy from a location of the product on the first conveyor slightly above the rounded end of the packaging on the first conveyor when the packaging on the first conveyor is correctly upright, and the second radiant energy sensor is positioned relative to the second conveyor to receive heat energy from a location of the packaging on the second conveyor slightly above the rounded end of the packaging on the first conveyor when the packaging on the first conveyor is correctly upright. 5. Method for detecting package misalignment (C) in the immediate delivery of finished glass packages, which consists of: sliding the package through the inspection point; placing an emitting energy sensor (20 or 22) at the inspection point, where the emitting energy sensor is focused to detect the thermal energy in the package in the cone section no larger than 1°; the emitting energy sensor detects the emitted energy from each package as it moves through the inspection point; and activating a solenoid (28) to reject the package when the emitted energy detected there does not match the emitted energy that should be detected from a correctly aligned package. 6. The method described in claim 5, whereby an emitted energy sensor measures the energy emitted from a location within each package slightly above the rounded edge of the package when the package is properly upright. 7. Method for measuring the deviation of the packaging arrangement (C) in the immediate delivery of finished glass packaging, which consists of: the first section of the package passing through the first inspection point; the second section of the package passing through the second inspection point; the placement of one radiated energy sensor (20) at the first inspection point, which is focused to measure the heat energy in a cone section no larger than 1°; the placement of one radiated energy sensor (20) at the second inspection point, which is focused to measure the heat energy in a cone section no larger than 1°; measurement by the first radiated energy sensor of the heat energy emitted from each individual package in the first section of the package passing through the first inspection point; measurement by the second radiated energy sensor of the heat energy emitted from each individual package in the second section of the package passing through the second inspection point. and moves through the second checkpoint, and activates the solenoid coil (28) which works in conjunction with the first energy sensor to reject packages on the first conveyor when the radiated energy measured from there does not match the radiated energy that should be measured from packages arranged correctly on the first conveyor. 8. The method specified in Claim 7, which consists of separating the second section of the shipped package and sliding it through the second checkpoint, prevents the radiated energy from being transferred to the first radiated energy sensor at the second checkpoint, thus preventing the first section of the shipped package from sliding it through the first checkpoint, thus transferring the radiated energy to the second radiated energy sensor at the second checkpoint. 9. The method specified in Claim 7, whereby a first radiated energy sensor measures the energy radiated from the first section of the exported packaging, slightly above the rounded heel of the first section of the exported packaging when the first section of the exported packaging is correctly upright, and a second sensor is positioned to receive heat energy from a location on the second section of the exported packaging, slightly above the rounded heel of the second section of the exported packaging when the second section of the exported packaging is correctly upright.
