Embodiment Construction

[0016] Now illustrate the present invention in conjunction with accompanying drawing and embodiment.

[0017] Such as figure 2 The shown tobacco foreign matter removal device introducing near-infrared spectrum technology mainly includes a tobacco foreign matter remover, which includes a material conveying device 7, an RGB vision system 2 and an injection valve 3, and also includes a near Infrared signal system 1.

[0018] Such as figure 1 The shown near-infrared signal system 1 includes a light source system, a spectroscopic system, and a signal collection system. The light source system adopts a tungsten-halogen lamp 11 . Described spectroscopic system comprises collimating lens 12,17, optical filter 13, lens 15, slit 16 and grating 18 that are provided with along optical path, the light that tungsten halogen lamp 11 sends becomes parallel light through collimating lens 12, After passing through the optical filter 13, it is irradiated on the sample 6, and after diffuse r...

Abstract

The invention discloses a near infrared spectroscopy introduced tobacco foreign material removing device. A near infrared signal system is introduced on the conventional tobacco foreign material remover, and the absorbance of the material at three sections of different near infrared wavelengths is selected and brought into a R (red) G (green) B (blue) three-color vision detection system so as to improve the sensitivity of the vision detection system and identify the tobacco and the foreign material more accurately. A corresponding removing method comprises the following steps of: determining three sections of wavelength intervals with obvious near infrared absorption difference between the tobacco and the foreign material; and then determining the range of tobacco absorbance in each section of wavelength, wherein after the production process is started, the tobacco foreign material remover determines the foreign material only by judging whether the absorbance of the sampled material in the three sections of wavelength intervals exceeds the range and then gives corresponding jet valve instruction to remove the foreign material.

Description

technical field [0001] The invention belongs to a device and a method for removing foreign matter in the cigarette production process. Background technique [0002] Foreign matter in tobacco will seriously affect the quality of cigarette products, which in turn will threaten the health of consumers. In order to ensure the quality of cigarette products, cigarette companies must take measures to remove them during the tobacco leaf redrying and shred production process. Foreign matter in tobacco is generally divided into two types: metallic and non-metallic. Metal foreign matter can be effectively removed by metal detectors. For non-metallic foreign matter, large domestic and foreign tobacco companies are usually in the silk production line or threshing and redrying. Tobacco foreign body removal system is installed online to remove it. [0003] The Tobacco Sorter series of SRC VISION in the United States and the Tobacco Scan series of Hauni in Germany are the most widely used...
