Intelligent digital double stay wire detecting system and method for cigarette package

Abstract

The invention relates to an intelligent digital double stay wire detecting system and method for a cigarette package. The system comprises a microcontroller, and a high-speed camera and an LED light source connected with the microprocessor; the LED light source is positioned in front of the high-speed camera, an optical center of the LED light source is intersected with that of the high-speed camera, and the center of the high-speed camera is aligned with a reference stay wire; and the microcontroller comprises a master control CPU and a memory and an LED touch screen connected with the mastercontrol CPU. A DSP processing technology is used, the operation speed is high, the processing capability is high, a complex algorithm can be adapted to, and existence or offset of different types ofdouble stay wires of the package can be detected accurately; the high-speed camera uses a full-visual-angle image visual detection manner, supports multi-wind application, and can freely set the detection range; and operation state and different types of operation data of present product detection can be displayed in real time by means of a touch screen display function.

Description

technical field [0001] The invention relates to the technical field of tobacco packaging quality detection, in particular to an intelligent digital double-wire detection system and detection method for cigarette stick packs. Background technique [0002] During the cigarette production process, the packaging box is wrapped with a layer of transparent wrapping paper, which plays the role of sealing and moisture-proof, and it is convenient for users to unpack the package through the pull wire. Problems such as the absence and deviation of the pull wire seriously affect the quality of the carton. [0003] At present, domestic cigarette companies attach great importance to the quality defects of CV wrapping and pulling wires, and have installed various detection devices for wrapping and pulling wires accordingly. They use micro-motion sensors with simple mechanical principles to detect the presence or absence of pulling wires, but cannot detect the presence or absence of pulling ...

Problems solved by technology

[0002] During the cigarette production process, the packaging box is wrapped with a layer of transparent wrapping paper, which plays the role of sealing and moisture-proof, and it is convenient for users to unpack the package through the pull wire. Problems such as the absence and deviation of the pull wire seriously affect the quality of the carton cigarettes.

[0003] At present, domestic cigarette companies attach great importance to the quality defects of CV wrapping and pulling wires, and have installed various detection devices for wrapping and pulling wires accordingly. They use micro-motion sensors with simple mechanical principles to detect the presence or absence of pulling wires, but cannot detect the presence or absence of pulling wires. Offset; After the packaging is formed, install the visual detection device for the strip pack. This type of detection is installed after the cigarette pack is formed. The price is high and there are missed and false detections. The light source attenuation of this detection method is fast, the detection accuracy is low, the detection is not sensitive enough, and the daily maintenance and adjustment are troublesome, etc.
