Technical Field

The invention relates to an anti-mixing detection method for an exploded bead filter stick, and belongs to the technical field of tobacco equipment.

Background

The bead-blasting cigarette is characterized in that a capsule wrapped with a liquid substance is embedded in a cigarette filter tip, and the bead-blasting cigarette can be pinched broken according to the will of a consumer when in use, so that the content in the capsule flows out, and the taste of the cigarette is enriched. As the tar release amount of cigarettes decreases year by year, the cigarette taste becomes lighter, so that a flavor compensation technology represented by the addition of popping beads is rapidly developed in the tobacco industry. In recent years, the domestic tobacco industry initially makes a series of research progresses on the production equipment and detection device of the bead blasting filter stick and the influence of bead blasting on harmful components in smoke.

The bead blasting filter stick is a filter stick made of blasting beads with special fragrance added in the filter stick forming process, and the blasting beads in the filter stick are not allowed to have the defects of bead blasting, hollow beads, bead shortage, bead blasting of different brands and the like in the production process. The invention patent with publication number CN107485050A discloses a defective product detecting and removing system of a capsule filter stick forming machine set and a using method thereof, wherein the defective product detecting and removing system comprises: the device comprises a detection device and a rejection device; the detection device comprises: the image collector is arranged between the strip breaking device and the lead-in cutting device; the image collector is positioned right above the conveying device, the image collector is connected with the controller and the image processor, and the image processor is connected with the controller; the removing device comprises a cigarette separating wheel body, a plurality of separating strips used for receiving the capsule filter sticks are uniformly arranged on the circumference of the cigarette separating wheel body, a removing electromagnetic valve connected with the controller is further arranged on the cigarette separating wheel body, the removing electromagnetic valve is connected with an air blowing pipeline, and the air outlet end of the air blowing pipeline faces the outside of the cigarette separating wheel body. The invention can detect the position of the capsule in the capsule filter stick in the production process of the capsule filter stick so as to detect and remove the defective products, thereby solving the problems of capsule loss and over-standard longitudinal deviation which often occur in the actual production of the capsule filter stick. The disadvantages of this device are: for the capsule with small damage degree, for example, the volume of the capsule is more than three fourths of the normal capsule, when the angle facing the image collector is just the largest area, the capsule has no difference with the normal capsule, thereby causing the detection omission.

The device of the invention is arranged on a filter stick forming machine. The microwave detection device in front of the breaking device detects broken beads, empty beads and missing beads of the broken beads 1 in the passing broken bead filter rod 2, then the broken beads are cut into broken bead filter rods 6 meeting the length requirement through the breaking device, and then the broken bead filter rods are further subjected to mixed bead detection in the moving process; (2) an image acquisition device: the image acquisition device is positioned right above the bead blasting filter stick and can capture the shape and color characteristics of the bead blasting in the passing filter stick; (3) an image processor: accurately processing the image captured by the image acquisition device, identifying the color and shape characteristics of the exploded beads in the filter stick, judging whether the bead is missing or not and whether the color of the exploded beads is consistent with the produced brand or not, and outputting a result signal to the removing device; (4) transparent structure of accepting: the transparent receiving structure of the filter stick after the strip cutter is made of transparent wear-resistant materials, and the structure of the transparent receiving structure can be a combined type structure with the whole length being made of transparent materials or with a part of transparent length and the other part being non-transparent; (5) light source: the light source is positioned right below the transparent bearing structure and faces the image capturing device, and the range of the light source is not smaller than the capturing range of the image capturing device. To prevent different brand of pop-beads from mixing, a first brand of pop-beads may be colored a first color, such as yellow, and a second brand of pop-beads may be colored a second color, such as green. The microwave detection device of the invention detects whether the bead is broken, empty and lacking, and the detection device behind the strip breaking device detects whether the brand is mixed.

As shown in figure 1, in the process of forming a filter stick, an exploded bead filter stick 1 containing exploded beads 2 enters a resonant cavity of a microwave generator of a detection device along the motion direction to detect broken beads, empty beads and missing beads, enters a strip cutter 4 after detection, is cut into an exploded bead filter stick 6 meeting the length requirement, then enters a transparent bearing structure 7, at the moment, a light source 8 right below the transparent bearing structure 7 is lightened and is directly upwards irradiated towards the transparent bearing structure 7, light rays are used for lightening the passing exploded bead filter stick 6 through the transparent bearing structure, an image acquisition device 5 located right above captures the shape and color characteristic images of the exploded beads in the exploded bead filter stick 6, an image processor is used for accurately processing the image captured by the image acquisition device, the characteristics of the color, the shape and the like of the exploded beads in the filter stick are identified, and whether the colors of the missing beads and the exploded beads are consistent with the produced brand is judged again, and a result signal is output to the removing device, and the removing device can accurately remove the filter rods which do not meet the requirements, so that the quality of the bead-blasting filter rods is ensured.

The filter stick containing the exploded beads is flatly placed on the transparent carrying structure, the bottom of the transparent carrying structure is provided with a light source, and the light source can be a single light source or a combination of multiple light sources and can be selected as required. When the bead blasting filter stick is detected, the light source irradiates the filter stick to be detected, and the light source can penetrate through the bead blasting filter stick, so that the color of the bead blasting filter stick can be obviously displayed. The irradiation range of the light source can be full-range irradiation of the bearing structure or partial irradiation. An image capturing device in the detection device captures images of a filter stick to be subjected to bead explosion, the characteristics of the filter stick such as the shape and the color of the bead explosion are captured to form images, an image processor in the detection device accurately processes the images captured by the image capturing device, the characteristics of the filter stick such as the color and the shape of the bead explosion are identified, whether the color of the bead explosion is consistent with a produced brand is judged, and a result signal is output to a rejecting device. The detection device can perform all-range disposable detection on the bead blasting filter stick in the bearing structure and can also perform single-point detection. When single-point detection is carried out, the exploded beads in the bead-exploded filter stick are sequentially detected through the detection points.

The detection mode can be used for off-line detection and can also be used for composite on-line detection with production equipment.
