Description

Technical Field

[0001] The present application relates to the technical field of cigarette inspection, and more specifically, to an inspection device for air suction holes of a finished cigarette filter segment. Background Art

[0002] In order to maintain the air permeability of cigarettes during smoking, pre-punching or online punching is performed at specific locations on the tipping paper during the production process to form air suction holes. The punched tipping paper is coated with paper glue by the glue roller, cut into paper pieces by the paper cutting wheel, and the paper pieces and cigarette groups are combined on the converging drum and rubbed and spliced ​​into shape under the action of the rubbing drum. Figure 6 The structure diagram of a cigarette 800 is shown, wherein the filter segment 810 thereof is provided with one or more circles of air suction holes 820 circumferentially.

[0003] In the cigarette production process, punching failures often occur due to faults in punching or the suction holes are clogged due to uneven glue coating, resulting in quality defects such as unqualified ventilation rate and suction resistance of the finished cigarettes. Therefore, operators need to check the suction holes of the cigarette filter segment tipping paper from time to time.

[0004] In the prior art, one method for checking the air suction holes is that an operator removes a complete piece of tipping paper, points a light source through the tipping paper, and checks the light transmittance of the air suction holes, thereby checking whether the glue mark on the tipping paper covers the air suction holes. Although this method is reliable, it is difficult for operators to completely remove the tipping paper, and the inspection efficiency is low.

[0005] Another way is to put the cigarette on a fixed seat and check it through a magnifying glass. However, it is difficult to distinguish the air intake hole due to the color of the tipping paper, and the air intake hole is small and difficult to observe. Utility Model Content

[0025] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0026] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0027] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0028] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0029] The present application provides an inspection device for the air suction holes of a finished cigarette filter segment. Light is irradiated from the end face of the filter segment from the inside to the outside. With the help of the light transmission phenomenon, the air suction holes are easier to observe. At this time, the light transmittance of the air suction holes is obtained from the outside, and there is no need to remove the tipping paper, thereby improving the inspection efficiency.

[0030] like Figure 1-5 As shown, the inspection device for the air suction holes of the finished cigarette filter segment provided in the present application includes a base 200 and a lamp holder 100 .

[0031] The base 200 is provided with a bearing surface 240 and a boss 250 protruding from the bearing surface 240. The bearing surface 240 is provided with at least one cigarette bearing groove ( Figure 1 Two cigarette carrying slots 210 and 220 are shown, and a detection hole 230 connected to each cigarette carrying slot is provided at the bottom of the boss 250, and the detection hole 230 passes through the boss 250.

[0032] The lamp holder 100 is arranged on a side of the boss 250 away from the bearing surface 240 and is detachably connected to the boss 250. After the two are connected, a closed space is formed in the lamp holder 100; a light source 600 is provided at a position corresponding to each detection hole 230 in the closed space.

[0033] In the detection state, the cigarette 800 is located in the receiving groove formed by the cigarette supporting groove and the detection hole 230, the end of the filter segment 810 of the cigarette 800 is aligned with the end of the detection hole 230, and the suction holes on the filter segment are exposed outside the detection hole 230.

[0034] As an embodiment, the cross-section of the cigarette carrying groove is semicircular.

[0035] Preferably, different cigarette holding slots on the holding surface 240 are suitable for cigarettes of different thicknesses. Figure 1 As shown, the cigarette holding slot 210 is used for thick cigarettes, and the cigarette holding slot 220 is used for thin cigarettes.

[0036] like Figure 5 As shown, the light source 600 includes a base 610 and a lamp body 620. The base 610 is detachably mounted in a corresponding limiting groove on the inner wall of the lamp holder 100. A connection point with the external wire 300 is provided in the base 610. The external wire 300 passes through the top surface of the lamp holder 100 from bottom to top, and the upper end of the external wire 300 is connected to a power source for lighting the light source 600.

[0037] Preferably, a condenser sheet 700 is sandwiched between the light source 600 and the end of the detection hole 230 , and the condenser sheet 700 is used to better concentrate the light from the light source 600 to the end of the filter segment 810 .

[0038] As an embodiment, the light source 600 is a lamp emitting warm white light, preferably an LED lamp.

[0039] Preferably, a through hole is provided from top to bottom at a position corresponding to the cigarette bearing slot on the boss 250, the through hole is connected to the corresponding detection hole 230, a photoelectric switch 400 is installed in the through hole, and the photoelectric switch 400 is connected to the power signal. When there is a cigarette in the base, the photoelectric switch 400 controls the light source to turn on, and when there is no cigarette, the light source is not turned on, which is energy-saving and environmentally friendly.

[0040] When checking cigarettes, put the cigarette into the cigarette bearing slot that matches its circumferential size, and place the end of the filter segment close to the condenser 700. At this time, the filter segment is close to the photoelectric switch 400 above, and the photoelectric switch 400 is triggered, so that the power starts, the light source 600 lights up, and the high-brightness light shines through the condenser 700 to the end face of the filter segment. The light shines through the filter from the inside to the outside of the air intake hole, and the air intake hole is clearly visible. The light transmittance of the air intake hole can be evaluated by the naked eye. If the air intake hole is blocked, the light transmittance is small, and the air intake hole is dark; if the air intake hole is not blocked, the light transmittance is large, and the air intake hole is bright. Therefore, according to the brightness of the light, the glue condition of the tipping paper and whether the air intake hole is blocked can be quickly judged.

[0041] The above manual judgment of light transmittance has a large error. Based on this, preferably, the inspection device also includes an image collector and a controller. The image collector is arranged above the cigarette carrying slot. The shooting range of the image collector covers the air suction hole. The controller is connected to the image collector signal. The controller is used to calculate the relative transparency at the air suction hole based on the image of the air suction hole provided by the image collector.

[0042] As an embodiment, the relative transparency at the air suction hole is calculated based on the image at the air suction hole provided by the image collector, specifically including:

[0043] P1: Preprocess the image provided by the image collector to obtain a first image in an area within a preset distance centered on the air suction hole and a second image outside the area;

[0044] P2: Analyze the first image and the second image respectively to obtain the transparency of the first image and the transparency of the second image.

[0045] As an embodiment, for each image (for example, in png format), the open source image processing library CXImage is used to read the image, and then the Encode method of SRC is called with the type parameter set to CXIMAGE_FORMAT_JPG to convert it to jpg format, and then the Encode2RGBA method of SRC is called to obtain the transparency information.

[0046] P3: Calculate the ratio of the transparency of the first image to the transparency of the second image.

[0047] P4: If the ratio is greater than the threshold, the light transmittance of the air intake hole is qualified and the air intake hole is qualified; otherwise, the light transmittance of the air intake hole is unqualified, the air intake hole is blocked, and the air intake hole is unqualified.

[0048] As an embodiment, the inspection device further comprises an alarm, which is connected to the controller by signal. If the light transmittance inspection fails, the controller controls the alarm to sound an alarm.

[0049] Preferably, the controller further comprises a display for displaying the image acquired by the image collector and / or the light transmittance inspection result.

[0050] Although some specific embodiments of the present application have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are only for illustration, not for limiting the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
