TH33601B - A cigarette manufacturing machine that includes a bar check - Google Patents

Abstract

The DC60 (30/11/54) system for optical monitoring is mounted on a cigarette or similar machine and will detect the presence of strips. with unusual width or spacing In response to the detection of abnormal bands System for Optical Inspection It will instruct the cigarette maker to remove cigarettes which will be produced in the next order out of the abnormal striped roll of paper. Optical examinations include probes, which can be used with different types of cigarette paper and banding materials with different reflectivity. The circuit for the detector detects the range of potential difference that has been generated by Inspection machine for measuring device and it is generated as the maximum (or average peak) for a range of potential differences. The percentage of this peak is taken as the default value. This default value is compared with the AC signal from the detector for the detector. If the AC signal exceeds the initial value then the circuit will Displays a signal to indicate that a bar is present. The detector's output signal is fed to the computer, where the computer checks that the bar is present. detected is the distance and width of Is the bar normal? The optical inspection system is mounted on the cigarette maker or the like. and it will detect the presence of the bar. with unusual width or spacing in response with the detection of abnormal bands System for Optical Inspection will order the cigarette maker to eliminate cigarettes which will be It is produced next from the abnormal striped roll of paper. The optical inspection system consists of a probe that can be used with different types of smoking paper and striped material. have different reflective properties in practice The circuit for the detector detects The range of potential differences that have been created by Inspection machine for measuring device This is then generated as the maximum (or average peak) for a range of potential differences. The circuit then takes a percentage of this peak as the default value. AC signal from the detector for the detector If the AC signal exceeds the default value then the circuit will show a signal to indicate that the bar is present. that the bar has been Is the detected bar spacing and width normal?
