Definitions

  • the invention relates to a method for testing cigarette heads, wherein at least a portion of a cigarette head Illuminated light and light reflected from the cigarette head like this is received by a detector that is irradiating and received reflected light run at an angle to each other and the irradiated area is imaged on the detector and on signal generated by the detector is evaluated. Furthermore concerns the invention a device for testing cigarette heads with a light source and optics for generating at least an area illuminated by light on a cigarette head and a detector for receiving reflected from the cigarette head Light arranged in such a way that irradiating and received reflected light run at an angle to each other and the irradiated area can be imaged on the detector.
  • 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 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. Finally, the pixels, the inside and outside of a narrow area lie an imaginary, theoretical straight line, counted and in put a relationship to each other. If this ratio is one Limit value is exceeded, this should indicate that a cigarette is not properly filled.
  • This type of testing has the disadvantage that it is inaccurate and no exact statements about the condition of a cigarette allowed.
  • the invention is therefore based on the problem of testing of cigarettes to improve and more accurate statements about the To allow condition of a cigarette.
  • the method according to the invention is used to solve this problem characterized in that a possible deviation in the evaluation, especially a distance, the position of the figure of the irradiated area from an expected position of one Illustration of a corresponding area of an ideal cigarette head is determined on the detector, being from the deviation the distance of the irradiated area to a target position this range is determined.
  • the problem is also solved characterized by a device according to the invention is by an evaluation device, the one from the detector generated signal evaluates to any deviation, in particular a distance, the position of the image of the irradiated Range from an expected position of an illustration of a corresponding area of an ideal cigarette head determine the distance of the irradiated from the deviation Determine range to a target position of this range.
  • a cigarette head can be made contactless be measured.
  • the light steel of a laser is preferred or other bright light source used and over a lens focused on a cigarette head. This will one or more pixels are essentially illuminated at the measuring distance.
  • a lens focuses the reflected light on you position sensitive detector. If the illuminated area is not in its target position, this leads to a deviation of the pixel on the position sensitive Detector or a deviation in the image of the illuminated Area in relation to an expected position of the figure on the detector.
  • the invention achieves very high measuring accuracy. Further A snapshot of the cigarette head is enough to cover these distances to investigate. This allows a cigarette head to move and be measured without contact. This allows a high one Operating speed of the cigarette packaging or cigarette manufacturing machine.
  • FIG. 1 shows a test device 10 for testing cigarette heads with a light source in the form of a laser 11.
  • a light source in the form of a laser 11.
  • other light sources with bright Light can be used that is monochromatic or non-monochromatic as well as non-coherent like bright LEDs.

  • Reflected light 20 received by the detector 19 is in one non-zero angles to the irradiating light 18, i.e. the light rays incident on the cigarette heads 16 are in a direction different from the direction of incidence Reflected towards the detector 19.
  • the detector 19 points in addition the CCD chip also has an optic 21, in particular an optic lens inside. This optics 21 serves to reflect the reflected Focus light rays 20 on the CCD chip.

  • the cigarette formation 17 is shown in FIG. 1 as a whole, three-layer Formation checked. Therefore, the detector 19 also detects the cigarette heads 16 are all within the cigarette formation 17 cigarettes located.
  • the evaluation device must therefore a picture consisting of one of the number of cigarettes Formation 17 corresponding number of drawing files, namely 20, evaluate. This check of the cigarette formation 17 is preferred on the cigarette turret of a cigarette packaging machine instead of. If a faulty cigarette occurs during this test procedure is recognized, this leads to the ejection of the corresponding faulty cigarette formation 17.
  • FIG. 2 shows a further test device 23, that of the one in FIG. 1 with the following exception:
  • the light beam 12 does not reach the lens diaphragm system directly 13, but is first of all via an optical system 24, in particular with a lens 25.

  • the test device 23 corresponds otherwise of the test device 10 according to FIG. 1 on the description thereof is hereby referred.
  • the glass fiber line 26 is used to have a light source 11 can also arrange in a different place than in the immediate Proximity to the lens aperture system 13. This has the advantage that some of the components of the test device 23 can be arranged there is where there is enough space. Other components, like the lens diaphragm system 13, can then in immediate Proximity to the cigarette or cigarette formation 17 housed his. Accordingly, the detector 19 can be accommodated elsewhere his. For this purpose, the detector 19 is also via a Optical fiber line optically connected to the location of the cigarette test. The reflected light 20 is then a small one Optics focused in a corresponding fiber optic line. Thereby you get more space in the area of the cigarette to be tested or cigarette formation.
  • Apertures 15 also use a hologram to create a structured Light patterns on the cigarette heads 16 of the cigarette formation 17 to generate.
