Definitions
- the invention relates to a method for testing cigarette heads, being light in at least two different ones Strip-like sections incident on the directions Face of a cigarette head shines and from the face reflected light received and evaluated by a detector becomes.
- the invention further relates to a device for Testing cigarette heads with at least two light sources for illuminating a strip-like section of each Front face of a cigarette head from different directions and a detector for receiving from the face reflected light.
- Test methods and test devices for non-contact are known Checking cigarette heads where one or several straight lines are blasted onto the tobacco-side cigarette head become. If the cigarette does not work properly with tobacco the line appears - if it is filled by another Viewpoint is viewed - no longer as a straight line, but as a serpentine line or as a broken serpentine line. This image is captured by a sensor. Finally be the pixels that are inside and outside a narrow Area around an imaginary, theoretical straight line, counted and related to each other. If this Ratio exceeds a limit, this should indicate that a cigarette is not properly filled.
- the invention is therefore based on the problem of testing Improve cigarettes and make more accurate statements about the condition to provide a cigarette.
- the method according to the invention is to solve this problem characterized in that when evaluating a distance between two resulting from a signal generated by the detector, with lines corresponding to the strip-shaped sections is the position of the irradiated by the sections To determine the area of the cigarette head. Furthermore, that Problem solved by a device according to the invention, which characterized is for evaluation by an evaluation device a signal generated by the detector, which is formed in this way is by a distance of two resulting from the signal, lines corresponding to the strip-shaped sections to determine the position of the irradiated by the sections To determine the area of the cigarette head.
- the invention makes use of the knowledge that two are on top of each other tapered light strips that act as strips of light on a Object to be measured, namely hitting a cigarette head, information about the distance of the measuring object to the measuring arrangement or another Give fixed point or generally about the position of the measurement object.
- the distance between the two hits the object to be measured Strip of light the desired information about the position of the Target.
- This type of contactless testing of cigarette heads is suitable especially for recess filter cigarettes or papyrossi cigarettes, with these cigarettes the light streaks too on the front of the cigarette tube or the mouthpiece tube hit at least partially and also from these areas reflected light received and evaluated by the detector becomes.
- These point-like light spots provide an orientation point for the end of the cigarette or mouthpiece.
- the streaks of light striking the tobacco or filter lie with these cigarettes (with a hollow mouthpiece) compared to the Mouthpiece end edge back.
- the depth of the mouthpiece sleeve can therefore from a distance of the images of these point-like Light spots or strips of light can be determined on the detector.
- the result of the test can be used to generate an error signal be used when a cigarette has predetermined limits does not comply.
- Such an error signal leads to the ejection of a Cigarette in the cigarette manufacturing or packaging process.
- a formation of several layers is preferred at the same time checked by cigarettes and, if necessary, if a faulty one occurs Cigarette ejected the entire formation.
- the light rays 15 emanating from the light sources 13, 14, 16 each arrive at an optic or a lens aperture system 17, 18 or to a hologram which the Light beams 15, 16 each in three light bands 19, 20, 21 and 22, 23, 24. These light bands 19 to 24 stand out Cigarette heads 25 of the cigarettes 12.
- the light strips have there 19 to 24 the shape of strip-like sections 26 to 31, as shown in Fig. 2. 2 are the end faces of the cigarette heads 25 shown in FIG. 1.
- the cigarette formation 11 consists of three layers, the two outer ones Layers of seven and the middle layer of six cigarettes consist. Depending on the location, two strip-like sections 26 and 27 or 28 and 29 or 30 and 31 on the end faces.
- the each upper strip-like sections 26, 28, 30 originate from the light source 13 shown in FIG. 1 above the lower strip-like sections 27, 29, 31 originate from the lower light source 14.
- Each strip-like section 26 to 31 covers a wide area the end face of the respective cigarette heads 25 and a little less than half of the face of each Cigarette head. Obtained by two strip-like sections therefore essentially an entire cover of the cigarette end face. This has the advantage that it enables an evaluation almost the entire face is possible.
- Fig. 1 also shows a detector 32, which from the end faces reflected light 33 receives.
- the detector 32 has optics 34, which serves to reflect the reflected light 33 onto one Focus sensor.
- This sensor contained in the detector 32 has a CCD chip that has a variety of two-dimensional arranged CCD elements. This makes it possible the illustrations of the strip-shaped sections 26 to 31 the end faces of the cigarette heads on the CCD chip.
- the individual CCD elements each emit a signal that flows to an evaluation device.
- the test device 10 described is preferably located on the cigarette turret of a cigarette packaging machine. she can also be arranged in a similar form on the cigarette magazine be and there a pre-sorting or an ejection of individual Cigarettes by means of an ejector arranged on the magazine make, as it / he in the German patent application DE 36 20 735 A1. At one on the cigarette revolver arranged test device leads to the detection of a faulty one Cigarette to eject the entire cigarette formation 11. For this purpose, an error signal is generated by the test device, that causes the ejector to eject.
- FIG. 3 shows a section along the line III-III from FIG. 2, that is to say a longitudinal section through a cigarette head 25.
- This cigarette head 25 has a filter piece 35, which is opposite the end of the mouthpiece sleeve 36.
- the incident Light strips 20, 23 irradiate the strip-shaped sections 28, 30 at the end of the filter piece 35. Also irradiate the light strips 20, 23 also the front of the mouthpiece necks 36 at end sections 37, 38.
- These sections 28, 29, 37, 38 illustrate the illuminated sections at a recess filter cigarette.
- a similar picture would turn up result in a Papyrossi cigarette, but then the filter piece 35 is replaced by tobacco.
- FIG. 4a shows a longitudinal section through a cigarette head 41 a tobacco-free cigarette with an end face 42.
- Fig. 4b shows the image obtained on the detector 32 when illuminated the end face 42 with two light strips, which as streak-like sections strike the end face 42.
- FIG. 4c shows the generated or generated by an evaluation device calculated image. This picture does not necessarily have to be presented become. It is sufficient that the data on which this picture is based can be calculated to carry out the invention. From the middle Sections 48, 49 each have a line of focus 54, 55 determined. The focus lines 54, 55 are advantageous calculated so that they are parallel to each other. Moreover the end sections 50 to 53 each become a focal point 56 to 59 united.
- FIG. 6a again shows the cigarette head 41 of a filterless one Cigarette, but with a piece of the tobacco filling missing. This results in a hole 60.
- an upper one Strip of light on the detector covering an upper section of the Face of the cigarette head 41 is detected, is therefore in the upper middle section 48 in FIG. 6b to recognize an irregularity.
- the middle section 48 of Figure 43 is namely not essentially level, but falls off to the side.
- Fig. 6c shows the calculated from it Center of gravity lines 54, 55.
- the center of gravity line shown in Fig. 6c 54 is compared to that shown in Fig. 4c Center line 54 shifted towards the center of the cigarette.
- FIG. 7a shows the cigarette head 61 of a recess filter cigarette with a filter piece 62 and a hollow mouthpiece 63.
- the as stripe-like sections hitting the cigarette head 61 Streaks of light appear as Figures 64, 65 on the detector 32 shown in FIG. 7b.
- There are middle sections 66, 67 of the cigarette shifted towards the cigarette axis.
- the end sections 50 to 53 are in the same position as in Fig. 5b for a completely filled cigarette.
