Definitions

  • the invention relates to a measuring method for detecting the position of a particular capsule-shaped object in a longitudinal axial funded filter strand of the tobacco-processing industry.
  • the invention further relates to a corresponding measuring arrangement and a machine of the tobacco-processing industry.
  • capsules are introduced into the filter material containing special flavors, usually in liquid form.
  • the capsules can be crushed by the consumer just prior to consumption to release the flavorings targeted and fresh into the filter.
  • a capsule with an insertion device automatically inserted into the filter train of a production machine per capsule a capsule with an insertion device automatically inserted into the filter train of a production machine.
  • the WO 2009/099793 A2 discloses a measuring device for determining the state of an object in a filter rod of a filter rod manufacturing machine.
  • the state to be detected includes, for example, the absence of an object, erroneous arrangement or faulty object.
  • the measuring device may for example comprise a microwave sensor, a beta radiation sensor, an infrared sensor or an X-ray sensor.
  • From the DE 10 2009 017 963 A1 is a microwave measuring device for determining the position of the capsule in the longitudinal direction of the strand in a filter rod machine known. Depending on the measurement signal, the rotational speed of a capsule insert pad or a cutting device for cutting the filter strand into filter rods can be regulated.
  • the capsule may be damaged or destroyed, in particular in further processing processes.
  • a filter with a capsule in a cigarette manufacturing machine is subject to different forces, for example when rolling with a launch bar. If the capsule is damaged or destroyed, the flavor is released uncontrollably and the desired controlled release by the consumer of the final product is no longer possible. So far, it is therefore attempted with great constructive effort to avoid mechanical stressing of the capsule, which is not always in the middle, from the outset, for example by means of undercuts, avoiding guides close to the capsule, But these efforts are set constructive limits.
  • WO 2011/083406 A2 discloses measuring methods for detecting an object in a longitudinally-axially conveyed filter rod of the tobacco-processing industry, wherein the filter rod is irradiated on the shell side along at least three optical axes which are arranged mutually independently of one another.
  • EP 1 557 100 A1 discloses a device for testing a filter strand of the tobacco processing industry in the transmitted-light method, wherein the light propagates by scattering in the filter material of the filter strand conically in the filter strand.
  • US 4,986,285 discloses a method for determining the density of tobacco material in a tobacco rod by irradiation with infrared light along three independent optical axes.
  • the object of the invention is to provide a measuring method and a measuring arrangement in which the likelihood of damage to the object in the filter production or processing and thus of a defective end product can be reduced.
  • the invention solves this problem with the features of the independent claims. Due to the shell-side radiation of the filter strand by means of at least three optical axes which are arranged mutually independently, the position of the object in two directions perpendicular to the strand axis can be determined in a simple manner with high accuracy. Based on the determined location of the object Different suitable measures can be taken to prevent damage to the inserted object during further processing. Elaborate constructive measures to avoid mechanical stress of a non-central object are dispensable due to the invention. Finally, the use of an optical measuring device is generally less expensive and thus considerably less expensive than microwave measuring devices used in the prior art. If the position of the object in line direction is also advantageously determined from the measurement signals, a maximum position information in all three spatial directions is available.
  • the object can be filled with a hollow object and with a liquid flavor in particular. It is preferably discrete, ie non-continuous in strand orientation, with regular axial spacing are arranged to each other, in particular capsules or balls.
  • a continuous object such as, for example, a flavor-impregnated thread is not excluded in principle.
  • the optical measuring device preferably operates in the visible wavelength range and / or in the infrared range. Also conceivable is an ultraviolet measuring device.
  • the optical axes of the measuring device mutually enclose an angle of at least 30 °, more preferably at least 45 ° with each other, whereby the accuracy of the position determination can be increased.
  • the optical axes are arranged at uniform angular intervals around the filter strand around.
  • each optical axis is associated with a uniaxial measuring device with a light source and a sensor.
  • the light source and sensor of each measuring device are arranged on opposite sides of the filter strand.
  • the measuring devices therefore work advantageously in the transmission method.
  • the number of optical axes is three, whereby the invention is realized with minimal effort.
  • a deviation of the determined position is determined to a desired position. This allows an advantageous good-bad evaluation of the position of the object based on a comparison of the determined deviation with a preferably adjustable threshold value.
  • a position signal containing information on the detected position of the objects is preferably provided automatically and continuously.
  • the position signal is provided in a clock-wise relative to the clock of a machine of the tobacco processing industry.
  • the position signal can advantageously be controlled means for inserting the objects in the filter strand.
  • an adjustment or regulation of the two-dimensional position of the inserted object can advantageously also take place perpendicular to the strand axis, the actual value of the layer measured by means of the measuring device coinciding with the generally centric desired value of the layer in the filter strand. This has not been known in the prior art.
  • an adjustment or regulation of the axial position of the object take place.

  • the thus processed material strip 61 is subsequently fed to the filter rod machine 140, in particular through an inlet funnel 141.
  • a formatting device 53 is provided which forms a filter strand 40 from the filter tow strip 61 by wrapping it with a wrapping strip (not shown) drawn from a bobbin.

  • the loading device 42 is adjustable with respect to the axial position and / or the perpendicular position of the capsules in the filter strand.
  • the loading device 42 can be actuated by an electronic control unit 13 with regard to the axial and / or vertical position of the capsules in the filter strand.
  • the loading device 42 is disposed in the filter tow conditioning unit 120.
  • the filter strand 40 is cut by means of a cutting device 46 into filter rods 41, which usually have a multiple, for example twice the useful length.
  • a capsule is usually provided for each filter element corresponding to a cigarette.
