Definitions

  • the invention relates to a method for checking cigarettes with regard to correct formation of the same at the ends thereof with the aid of transmitter and receiver having electro-optical sensors, by means of which a test beam (light beam) is directed onto at least one end face (end face) of the cigarettes and reflected light is measured.
  • the invention further relates to a device for checking cigarettes.
  • the cigarettes are checked in connection with their packaging; The cigarettes are checked for correct, adequate tobacco filling with electro-optical sensors.
  • the testing of cigarettes with electro-optical sensors is basically known.
  • the methods used so far work either on the transmitted light principle or on the reflection principle.
  • the transmitted light principle requires powerful sensors that must also be so sensitive that they already react to slight differences in brightness.
  • the reflection method can sometimes only be used with great effort when checking cigarettes. Because of the unfavorable reflective properties of tobacco, test methods based on the reflective properties of tobacco can only be used in conjunction with powerful sensors.
  • the invention is therefore based on the object of offering a method for checking cigarettes by means of electro-optical sensors which works according to the reflection principle, but nevertheless delivers precise results with regard to checking for sufficient tobacco filling with very short test times.
  • the method according to the invention is characterized in that the test beam is directed at an acute angle, in particular at an angle of less than 45 °, onto the end face of the cigarette in such a way that light is reflected in the area of the same from cigarette paper in the absence of tobacco becomes.
  • the test beam hitting an inside of the cigarette paper at an acute angle is reflected in itself and registered by the receiver arranged concentrically with the transmitter. This method therefore uses the favorable reflective properties of paper to check the cigarette ends for sufficient tobacco filling.
  • a cigarette there are preferably two sensors lying opposite one another along the circumference are provided, which form a pair of sensors.
  • the sensors In particular the pair of sensors, are moved relative to the cigarettes, the end faces of the cigarettes being scanned by the test beams.
  • the cigarettes of a cigarette group are checked in several subgroups, the cigarettes in a subgroup being checked simultaneously.
  • the check can be carried out both during the standstill phases of a cigarette revolver and during its movement.
  • the cigarettes of a cigarette group are checked during the standstill phases in two successive test stations, with every second cigarette of all rows in the cigarette group being checked with a test unit.
  • all cigarettes in a cigarette group, divided into several sub-groups are checked one after the other.
  • the device for checking cigarettes essentially consists of a test unit, formed from a plurality of sensors, which are combined to form sensor pairs in a sensor carrier, in such a way that the individual sensors are at an angle smaller than the end faces of the cigarettes Include 45 °.
  • the sensor pairs are each arranged parallel to one another and at a distance from one another on the sensor carrier of the test unit, which distance corresponds to two sloping rows of the cigarette group.
  • two test units are provided for checking cigarette groups in a cigarette revolver which can be rotated in cycles. These are on in two successive test stations during the standstill phases of the cigarette revolver the end faces of the cigarettes can be moved in such a way that the sensor pairs can be moved back and forth parallel to the alignment of the oblique rows.
  • the two test units each have four sensor pairs. Every second cigarette of all rows in a cigarette group is checked in the test stations. The test units are moved back and forth by means of a rack and pinion drive.
  • the check takes place during the rotary movement of the cigarette revolver.
  • a test unit can be moved in two planes parallel to the end faces of the cigarettes, specifically axially axially to the longitudinal axes of the cigarettes.
  • the test unit has three pairs of sensors.
  • the two-axis movement of the test unit in the plane parallel to the end faces of the cigarettes is carried out by means of a swivel gear.
  • Another feature of the invention relates to the design of the swivel gear.
  • electro-optical sensors 11, 12, in which a transmitter and receiver part is integrated, are provided for fault identification and delivery of a fault signal.
  • 1 shows, as the simplest arrangement, a test unit 13, which essentially consists of a sensor carrier 14, which receives a sensor 11, 12 in each of its lateral end regions in inclined bases 15.
  • the cigarette 10 to be checked is arranged centrally between the two sensors 11, 12 and is located with its end face 16 at such a distance from the sensor carrier 14 that the test beams 17, 18 emanating from the sensors 11, 12 are at an acute angle 19 the Strike the end face 16 of the cigarette 10. In the present case, the angle 19 is 20 °.
  • test beams 17, 18 strike the inside of the cigarette paper 22 enveloping the tobacco 20. At least part of a test beam 17, 18 is reflected in itself and thus reaches the receiver of the sensor 11, 12. The sensor 11, 12 then generates a corresponding error signal.
  • test beams 17, 18 are absorbed by the tobacco 20, so that an error signal is omitted.
  • defects 21 have relatively flat tapered edge areas that occupy a large area of the end face 16, it is usually sufficient two sensors 11, 12 combined to form a pair of sensors 23 in order to identify defects 21 in the area of the end face 16 with sufficient certainty.
  • test of individual cigarettes 10 can take place while the cigarettes 10 are at a standstill or in motion, the test unit 13 being able to remain in the rest position or being moved.
  • the only decisive factor is that at a point in time of a relative movement between a cigarette 10 and the test unit 13 or the sensor pair 23, the test beams 17, 18 can strike the end face 16 of the cigarette 10 to be checked in the manner described above.
