Definitions
- the invention relates to a method for testing cigarette heads, taking multiple areas of a cigarette head with these Areas are illuminated according to structured light and light reflected from the cigarette head from one of them Detector is received that irradiated and received reflected Light at an angle, especially triangulation angle, to each other, the irradiated areas on the Mapped detector and one each generated by the detector, one Area assigned mapping is evaluated to if present a reject signal from an improper cigarette to create.
- the invention further relates to a device for testing Cigarette heads with a light source for generating structured Light around multiple areas of a cigarette head to irradiate, a detector for receiving from the cigarette head reflected light, being light source and detector spaced apart and at an angle, in particular triangulation angle are arranged to each other, and an evaluation unit for evaluating each generated by the detector images assigned to an area and for generating a Reject signal when there is an improper cigarette.
- a test method or a test device for non-contact is known Checking cigarette heads on one straight Line is blasted onto a tobacco-side cigarette head. If the cigarette is not properly filled with tobacco, the line appears - if it is from a different angle is considered - no longer as a straight line, but as Serpentine line or as a broken serpentine line. This Image is captured by a sensor. Eventually they will Pixels inside and outside a narrow area lie around an imaginary, theoretical straight line, counted and related to each other. If this ratio exceeds a limit, this is to indicate that a cigarette is not properly filled.
- the invention is therefore based on the problem of testing To improve cigarettes.
- This problem is solved with a method of the aforementioned Kind that is characterized in that the irradiated Areas are each areal and each figure evaluated based on several different criteria becomes. Furthermore, this problem is solved by a device of the type mentioned at the outset, which is characterized by that the light source irradiates the areas over a wide area and the evaluation unit is designed such that each image evaluate using several different criteria.
- the test device 10 for testing cigarette heads 11 of a cigarette formation 12.
- the test device 10 prefers to check the tobacco ends of cigarettes can also be used to test filter-side cigarette heads be used.
- the test device 10 has a light source 13 which has a plurality of preferably three, individual light sources, in particular laser diodes, having.
- the individual light sources 14 are each with Light lines 15 connected to that of the individual light sources 14 direct outgoing light to a lens aperture system 16, which comprises one or more lenses 17 and an aperture 18, which are housed in particular in a housing 19.
- That of the ends facing the lens aperture system 16 Light lines 15 outgoing light is substantially parallel aligned and each one shown in Fig. 1a circular cross section. That of the individual light sources 14 emitted light thus essentially enters in a columnar manner the lens aperture system 16. The light becomes like this widened by the lenses 17 and shaped by the aperture 18, that it's on the opposite side - the exit side - The lens aperture system 16 in turn essentially parallel, columnar structured and evenly shaped, exit. Through this structuring different Areas of a cigarette head 11 are illuminated in a clearly delineated manner become. That a cigarette head 11 is inside a one Area bordering circumference evenly with light irradiated. A cigarette head 11 is in several such Divided areas. The areas cover the largest overall Part of the face of a cigarette head.
- the light comes on the end of the lens aperture system facing the cigarette heads 11 16 not parallel, but converging or diverging out.
- the Light reflected by the cigarette heads 11 is emitted by one Detector 20, in particular a CCD camera, received.
- the Light source 13 or the lens aperture system 16 and the detector 20 are spatially spaced from one another at an angle, in particular triangulation angle 21.
- the ones irradiating the cigarette heads 11 also run in this manner and the reflected light rays received by the detector 20 at this triangulation angle to each other.
- the triangulation angle 21 is in the range between 10 ° and 80 °, preferably 20 ° and 60 °, more preferably 20 ° to 30 °, and is preferably essentially 25 °.
- the detector 20 has an output line 22 with an evaluation unit (not shown) is connected, by means of which images generated by the detector of the irradiated areas can be evaluated.
- the evaluation unit generated when there is an improper one Cigarette a reject signal. Such a reject signal leads to the rejection of the cigarette that is recognized as defective or cigarette formation.
- the individual light sources 14 are provided with a (not shown) Control unit connected by means of which the individual light sources 14 can be switched on and off individually.
- This control unit can be operated in such a way that only one light source at a time can be turned on while the rest are off stay. This way, those on the cigarette heads selected area are irradiated one after the other, so that interference between areas is excluded are. This is particularly advantageous if the areas are such are selected so that they partially overlap. However, if the areas are spaced apart or tangent are selected, the control unit can also be operated in this way that the individual light sources come in and out at the same time turned off. The test takes place in such a way that each area of a cigarette head of a cigarette formation is irradiated only once. This can happen during a momentary The cigarette formation comes to a standstill.
- Fig. 2 shows the aperture 18 in an enlarged view.
- the aperture 18 has one of a cigarette of the cigarette formation 12 associated opening 23 through which light unhindered can step through.
- the arrangement of the openings 23 corresponds the arrangement of the cigarettes within the cigarette formation 12th
- FIG. 3 shows the front of the cigarette formation 12 at 20 Cigarette heads 11.
- Each cigarette head 11 has several, namely three, uniform, in particular circular Areas 24 assigned one after the other or simultaneously with Be irradiated with light. These areas 24 arise in the same Way on each cigarette head 11 of the cigarette formation 12 thanks to the majority of the individual light sources 14 and the lens diaphragm system 16.
- the starting from an individual light source 14 Light is expanded through the lenses 17 and through the Aperture 18 structured so that on each cigarette head a circularly illuminated area 24 of the cigarette formation is produced.
- the expansion causes an overlap the areas 24 of different individual light sources 14 according to FIG the manner shown in Fig. 3.
- At a lower level an expansion of the areas can be avoided, so that the regions 24 are spaced apart or tangent to one another are arranged together.
- FIG. 5 shows a spaced arrangement of the areas 24 a cigarette head 11. With this arrangement, all three Area can be irradiated with light at the same time. alternative the areas can be arranged in such a way that they just touch the edges.
- FIG. 6 shows an image 25 generated by the detector 20 from several, namely three sub-areas 26. Because of the angular arrangement of light source 13 and detector 20, in particular in the triangulation angle 21, as well as the unevenness of the The surface of a cigarette head 11 is created in the detector 20 an image of the irradiated, for example, as shown in Fig. 4 Area 24 with several partial areas 26, between which apparently unilluminated areas 27. This apparently unlit areas 27 arise due to shadowing, that of the unevenness of the tobacco structure or filter structure be generated. The more pronounced these bumps the larger the apparently unlit areas or the more unlit areas are created. hereby the length of the circumference of Figure 25 increases or the total length of all circumferential lines of all partial surfaces 26.
- the invention has recognized that the length of the circumferential line is one Measure of the quality of the surface of a cigarette head 11.
- the length of the connecting lines is also preferred for the circumferential line between the centroids of the subareas 26 added, preferably only the lengths of the connecting lines the largest partial area 26 to the other partial areas become.
- Fig. 7 shows a cigarette head 11 with a compared to Fig. 6 more uniform surface, i.e. a surface with less roughness.
- Figure 25 only exists from a single surface, however, is the circular structure the illuminated area has given way to an irregular border. 6 and 7, the cigarette heads 11 are circular shown. In fact, a full Illumination of the cigarette heads 11 an elliptical border of the cigarette heads are imaged by the detector 20.
- FIG. 7 shows the illustration 25 in several, for example in FIG. 6 Sub-areas 26 shown, parts of Figure 25 are missing or the outline of Figure 25 is less smooth. Around the phenomena are binarized image signal received by the detector. The binarized in this way Mapping is then based on the criteria described in more detail below evaluated.
- 8A to H show eight different criteria of the evaluated Illustrations and their results for 25 cigarettes each.
- the 25 cigarettes are plotted on the abscissa, while the respectively determined values of a criterion on the ordinate.
- the cigarettes are 1 to 10 properly trained cigarettes while the cigarettes 11 to 25 are improperly formed cigarettes.
- FIG. 8B shows the total area of an image 25 as a criterion, possibly taking into account its partial areas 26. If the total area is above a limit value GR B , a cigarette is found to be good. Accordingly, a cigarette is found to be bad if the value of the total area is below this limit value GR B.
- 8F represents the sum of the weighted with the partial areas Distances between the centroids of the subareas 26 to the center of gravity of the largest partial area 26, without Normalization to the total area according to FIG. 8B. exceeds this weighted distance sum becomes a limit GRF the respective Cigarette approved. Accordingly, a cigarette found bad if the limit GRF exceeded becomes.
- FIG. 8A shows a representation of the weighted distance sum of the centroids of the partial areas derived from FIG. 8F in accordance with the above explanations, but normalized to the total area as shown in FIG. 8B. If a limit value GRA for the weighted distance sum with standardization for the respective total area is undershot, a cigarette is found to be good. Accordingly, a cigarette is rated as bad if this limit value GR A is exceeded.
- the maximum diameter of an image which is possibly measured over a plurality of partial areas 26.
- the maximum diameter can also be determined as the diameter of the convex circumference.
- the convex circumference denotes the curve with the shortest length that encloses all partial areas of an image. A cigarette is judged to be correct if it falls below a limit value GR D for the maximum diameter. Accordingly, a cigarette is found to be improper if this limit value GR D is exceeded.
- 8H correspondingly illustrates the minimum diameter of an image or by the partial areas of an image or the minimum diameter of the structure enclosed by the convex circumferential line. If the minimum diameter determined exceeds a limit value GR H , a cigarette is found to be correct. Accordingly, a cigarette is found to be improper if it falls below this GRH limit.
- 8C illustrates the mean diameter of an image, which can be determined as the mean value of the minimum and maximum diameter. Alternatively, this diameter can also be determined as the mean value of all the diameters resulting with respect to the convex circumferential line. If the average diameter exceeds a limit value GR C , a cigarette is found to be correct. Accordingly, a cigarette is found to be improper if this limit is exceeded.
- FIG. 8E illustrates the so-called elongation, which is determined as the ratio of the maximum diameter to the minimum diameter. If the elongation exceeds a limit value GR E , a cigarette is found to be correct; accordingly, a cigarette is found to be incorrect if this limit value is exceeded.
- the compactness is a measure that is calculated from the squared length of the circumference, which is divided by the product "4 ⁇ total area".
- the length of the circumferential line of an image is calculated taking into account the lengths of the circumferential lines of the individual partial areas belonging to an image, in particular taking into account the lengths of the connecting lines of the centroids from the largest partial area to the other partial areas. If the value of the compactness exceeds a limit value GR G , a cigarette is found to be correct, accordingly a cigarette is found to be incorrect if this limit value is exceeded.
- Another criterion is the so-called fracturing of an image.
- the fissure is determined from the length of the circumference in the sense of one of the above definitions in relation to the length of the convex circumference.
- the optically measured cigarette length is the optically measured cigarette length.
- two methods are available for this.
- the cigarette length can be determined from a triangulation measurement be won. This is useful if that of the Lens aperture system light directed towards the cigarette heads is formed in parallel. Any deviation is in particular a distance, the position of the figure of a irradiated area from an expected position of a Illustration of a corresponding area of an ideal cigarette head determined and from the deviation the length of the tested Cigarette calculated.
- Another method will from the size or area of a picture the length of the cigarette calculated. The prerequisite for this procedure is that that from the lens aperture system 16 onto the cigarette heads emitted light is not parallel, but diverging or is converging.
- FIG. 9 shows a table of the evaluation of the examinations shown in FIGS. 8A to H.
- a dot in this table indicates a cigarette that was found to be improper by the criterion assigned to the corresponding column.
- a reject signal is generated by the evaluation unit if at least one such point is assigned to a cigarette, ie if at least one criterion has been found to be improper.
- the limits of the criteria GR A to GR H are chosen generously, ie a cigarette tends to be found to be good rather than bad.
- At least two of the criteria explained are combined combined to generate a reject signal if necessary. It can also be three, four, five, six, seven, eight or more criteria for forming a reject signal with each other be combined. The greater the number of combined ones Criteria, the higher the level of reliability upon detection of an improper cigarette.
