Definitions

  • the invention relates to a test arrangement for testing the ends of cigarettes, in particular for detecting ends which are insufficiently filled with tobacco, with a conveyor for conveying the cigarettes past a first test station for the tobacco quantities in the cigarette ends.
  • the object on which the invention is based is to provide a further development of test arrangements of the aforementioned type.
  • the solution according to the invention is characterized by at least one further test station for detecting the tobacco quantities in the ends of the cigarettes conveyed on the conveyor.
  • An advantageous development of the invention is an embodiment of the first test station as a photoelectric test device for the cigarette ends. According to the invention, this can have at least one light-emitting light source emitting the cigarette ends and at least one light through the cigarette tubes in the end regions.
  • the first test device can have at least one light source designed as an infrared diode, which is assigned an optical system for parallelizing the emitted light.
  • An optical filter that filters out light outside the infrared range can be assigned to the photoelectric receiver having at least one infrared-sensitive photodiode.
  • Several photoelectric receivers can be arranged at a distance from one another, which detect the light passing through the cigarette tubes in different sectors of the end regions; To suppress extraneous light, the photoelectric receivers designed as photodiodes can be arranged in the channels delimiting the interrogation angle.
  • the further test station can have a capacitive test device.
  • the latter has a capacitor arranged in a high-frequency resonant circuit, preferably a stray field capacitor, the stray field of which penetrates the cigarette ends, a measuring arrangement being provided for an electrical value dependent on the amount of tobacco in the cigarette ends.
  • the further test station can have a photoelectric test device.
  • the photoelectric test device can have at least one light emitting light emitting onto the cigarette ends and at least one light depending on the nature of the cigarette ends-detecting photoelectric receiver.
  • the light source can be designed as a laser.
  • the photoelectric receiver can detect the light reflected from the cut surface of the cigarettes.
  • the light emitted by a light source can be directed to the cigarette ends and / or the light can be returned from the cigarette ends to a receiver.
  • the cigarette ends are in a defined position in relation to the test device, in particular in the further test station, at the time of the test. According to the invention, this can be ensured by a positioning arrangement which brings the cigarette ends into defined positions with respect to a test device at the time of the test.
  • a measuring device for detecting the distances between the cigarette ends and the testing device can also be provided, the distance-dependent measuring signal of which is taken into account when testing the cigarette ends becomes.
  • the advantage associated with the invention is that tobacco incompletely filled areas in the end area of the cigarettes (defects) which have not been detected by a test device are detected and displayed by the further test device, which preferably works by a different method.
  • the invention also relates to a test device for testing the ends of cigarettes, in particular for detecting ends which are insufficiently filled with tobacco, with a conveyor for conveying the cigarettes through a photoelectric test station with at least one light source emitting light on the cigarette ends and with at least one light through the Cigarette case in the head end area detecting photoelectric receiver.
  • the object on which the invention is based is to provide a further development of test devices of the aforementioned type.
  • the solution of the object according to the invention is that the light source is designed as an infrared diode, which is assigned an optical system for parallelizing the emitted light.
  • an infrared diode light-emitting diode
  • optics which makes the test largely independent of distance fluctuations between the cigarette ends and the light source.
  • An advantageous development of the invention consists in providing a photodiode, preferably an infrared-sensitive photodiode, as a photoelectric receiver, which is preceded by a filter which at least largely filters out light with a wavelength in the visible range.
  • the test device is at least largely independent of extraneous light.
  • a further advantageous embodiment of the invention can be achieved if a plurality of photoelectric receivers are provided at a distance from one another which detect the light passing through the cigarette tubes in different zones of the head end region.
  • the detection areas of the several photoelectric receivers are advantageously arranged symmetrically on the circumference of the cigarette ends. Badly filled ends can then be reliably grasped, even if the tobacco is distributed asymmetrically in them as desired.
  • the photodiodes in channels, e.g. B. holes.
  • Another advantageous embodiment of the invention consists in arranging at least one translucent cover in front of the photoelectric receivers.
  • Such covers e.g. B. made of glass, protect the optical and photoelectric elements from soiling caused by dust emerging from the cigarette ends, tobacco crumbs and the like.
  • the security of capturing e.g. B. asymmetrically filled cigarette ends can also be improved according to the invention in that the photoelectric receivers are connected in parallel in such a way that the output signal of a receiver triggers an error signal when a threshold value is exceeded.
  • a significant improvement in the test result can be achieved if the photoelectric test device according to the invention is combined with a further test device which capacitively detects the tobacco quantities in the cigarette ends.
  • the cigarettes to be tested are conveyed in succession past both test devices, it being irrelevant which test signal is generated first because the test is non-contact in both cases.
  • a defective cigarette end that is not recognized by one (eg photoelectric) test method is most likely detected by the other (eg capacitive) test method and vice versa.
  • other suitable measuring methods e.g. photoelectric
  • photoelectric can also be combined in further measuring devices.
  • the photoelectric test device 1 forms the essential part of the photoelectric test station B. It has a bright light source which preferably consists of a diode 2 (light emitting diode) emitting light in the infrared (IR) range.
  • An optical system 3 is arranged in the beam path of the emitted IR light, which parallelises the light. Between the optics 3 and the end 4 of a cigarette 6 to be scanned for sufficient tobacco filling, there is a translucent cover in the form of a glass plate 7, which mechanically separates the light-emitting part of the photoelectric test device from the cigarette end 4 and thereby prevents dirt or sticky tobacco crumbs get the sensitive optics 3.
  • the cigarette 6 is conveyed in receptacles 8 of a rotating test drum 9 known per se and therefore not shown in detail through the test area of the test device 1, wherein it is held in the receptacles 8 by suction air in channels 11.
  • the test drum 9 is provided with a plurality of receptacles 8 in which the cigarettes to be tested are conveyed successively through the photoelectric test station B.
  • the end region 4 of the cigarette 6 can be more or less filled with tobacco.
  • FIG. 2 shows a very poor filling, in which a number of tobacco particles 12 are missing.
  • the infrared light emitted by the light-emitting diode 2 and parallelized by the optics 3 and coming into the interior 13 of the cigarette end 4 is transmitted to the outside with a component in the direction of the arrows 14, 15, 16 and 20 deflected (only arrows 14 and 16 visible in FIG. 2) and thus illuminates the inside of the cigarette paper 17 which acts as a wrapper in the end region 4 of a cigarette 6.
  • a cigarette 6 is advantageously detected by several photoelectric receivers, preferably photodiodes 18, 19, 21 and 22, which are distributed symmetrically on the circumference and are arranged in channels in the form of bores 23, 24, 26 and 27.
  • the number of diodes and channels can of course be larger or smaller.
  • the holes prevent extraneous light from falsifying the test results.
  • Optical infrared filters 28, 29, 31 and 32 serve the same purpose, ensuring that only IR light can reach the photodiodes.
  • the four photodiodes each capture a sector 6a, 6b, 6c and 6d of the circumference of the cigarette end 4. It can be advantageous here that the scanned sectors overlap somewhat.
  • the outputs of the photodiodes 18, 19, 21 and 22 are connected to inputs of a threshold element 33 which responds as soon as even one photodiode indicates by its output signal that the peripheral sector of the cigarette end 4 which it has detected is illuminated, which indicates that as a result missing tobacco, part of the IR light emitted by the light-emitting diode 2 can reach the cigarette paper 17 in the end area and illuminate it. If there is a lack of as much tobacco as indicated in FIG. 2, then all photodiodes can emit output signals which can be attributed to an insufficient tobacco content in the cigarette end 4.
  • a particularly advantageous development of the invention consists of placing a further capacitive test station C upstream or downstream of the photoelectric test station B.
  • An arrangement is shown in FIG. 1, in which the path of the cigarette 6 to a capacitive testing device 34 known per se is marked by a dash-dotted line 36.
  • Insufficiently filled cigarette ends, which for some reason have not been detected by the photoelectric test device 1, are at least partially detected by the capacitive test device 34 or vice versa. This increases the security of the detection of such insufficiently filled ends considerably.
  • FIGS. 3 and 4 show details of the capacitive end test device 34.
  • the capacitive measuring arrangement 34 with an annular electrode 457 and an electrode 458 arranged concentrically thereto forms the end of a stationary sliding surface 501, which is a positioning device for the cigarette ends 406 with respect to the measuring electrodes 457 and 458.
  • a stationary sliding surface 501 which is a positioning device for the cigarette ends 406 with respect to the measuring electrodes 457 and 458.
  • the measuring arrangement 34 has a high-frequency voltage source 459b which supplies the electrodes 457 and 458, which are frequency-determining part of a known electrical resonance circuit 462, with high-frequency voltage of constant frequency stabilized by a quartz crystal.
  • An insufficient filling of the cigarette ends 404 i.e. Output signals from the optical test device 1 and the capacitive test device 34 which indicate too little tobacco can be used in a manner known per se to separate out the corresponding cigarettes, for which purpose a known electrically controlled blown air valve can be used.
  • FIG. 5 shows a variant, designated 101, of the further test station C.
  • the corresponding photoelectric test device 101 has a light source 102, which is advantageously designed as a laser.
  • the light beam 102a emanating from the laser reaches the cut surface 104a in the end region 104 of the cigarette 106.
  • the reflected part 102b of the light beam reaches a photoelectric receiver 118, e.g. B. a photodiode, which emits an electrical signal dependent on the amount of tobacco in the end region 104.
  • the cigarettes to be checked for their ends are successively moved past the photoelectric test device 101 on a conveyor. If it cannot be ensured (e.g. by means of a positioning arrangement corresponding to 501 in FIG.
  • a measuring device 151 can be provided for detecting the distance be.
  • the measuring device can have a light source 152 and an optic 153 for parallelizing the light on one side of the end region.
  • an array 154 of individual photodiodes 156a ... e (which are of course much more in reality) can be provided.
  • the number of exposed or vice versa of the unexposed diodes is then a measure of the distance between the cut surfaces 104a and the laser 102.
  • the number corresponding to the distance can be determined in a conventional evaluation arrangement 157.
  • the electrical signal corresponding to the distance value can be calculated in a computing stage 158 with the output signal of the photoelectric receiver 118 in such a way that the influence of distance fluctuations is eliminated.
  • FIG. 6 shows a variant 201 of the photoelectric test device in the further test station C, in which the light coming from a light source 202 is guided in optical fibers 261a ... d to the cut surface 204a of the cigarettes 206.
  • the reflected light is guided to the photoelectric receiver 218 via optical fibers 261e ... g. 5 and 6 are defined in a manner known per se by control elements which are synchronized with the conveyor of the cigarettes and then emit corresponding control signals when the cigarettes are in the test position.
