Definitions

  • the invention relates to a method for testing cigarette heads, with at least one area of a cigarette head Illuminated light and light reflected from the cigarette head like this is received by a detector that 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 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. 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 infected.
  • 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 to solve this problem characterized in that a possible deviation in the evaluation, in particular 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 for 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 any 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.

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 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 available. Other components, like the lens diaphragm system 13, can then in immediate Proximity to 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.
