Definitions

  • the invention relates to a method and an apparatus for adjusting the Diameter of a filter for rod-shaped articles of the tobacco processing Industry, for example for cigarettes.
  • Such methods and devices are from the prior art known.
  • the procedures and shown there Devices measure the filter diameter during the manufacture of the Filters and then regulate the based on the measured filter diameter Filter manufacture such that a constant filter diameter at the outlet a filter manufacturing machine, also called a filter maker is provided.
  • the object of the present invention is to implement the known methods and Improve devices.
  • the advantages of the invention are in particular that Filter diameter at the point of further processing, i.e. usually on Filter attachment, very precisely a desired target diameter can be set accordingly. This is important because at Cigarette filters of large diameter (or derived from the circumference) Significance for the pull resistance and the condensate retention when pulling on the cigarette and also for the process of attaching the filter to the Tobacco stick is.
  • Deviations can already occur in the filter attachment process at the filter attachment from a few 1/100 mm from the nominal diameter to an additional, lead to undesired ventilation in the area of the bond.
  • the invention includes the finding that exact compliance with the However, this is one of the reasons why the diameter of the filter during manufacture is difficult because the filter diameter depends on the humidity of the material used to make the filter, e.g. a cellulose acetate tow, is.
  • the diameter of the filter is now used for control purposes e.g. in one measurement tower operated outside the production line the filters a certain time before and / or during the measurement Indoor climate of the measuring tower exposed, which mostly not Indoor climate corresponds to the filter production and thus change their Humidity.
  • the moisture change is also between the elapsed time Production and measurement dependent, but runs mostly because of highly porous paper cover of the filter relatively quickly. This changes the diameter of the filter, so that the control unit on the measuring tower detects a different diameter than the diameter measuring device on the Filter making machine. Corrective measures initiated on The output of the filter manufacturing machine is then unauthorized.
  • the expected change will therefore solve these problems preferably based on a comparison between the moisture of the Filter material with the relative humidity of the ambient air future location of the filter, e.g. at the filter attachment, determined.
  • the relative air humidity of the ambient air of the future lounge area can be assumed as known or measured when determining the expected change.
  • the moisture of the filter material can in turn be in one Range of measurement of the filter diameter and / or in the range of Stock and / or in an area before the production of the filter on the filter material used to manufacture the filter can be measured.
  • a Set target diameter of the filter and the setting of the Diameter taking into account the expected change made such that despite the expected change in the Target diameter is reached.
  • the desired diameter is preferred in the future lounge area reached or at a predetermined Processing time of the filter reached.
  • Fig. 1 is an example of a device according to the invention Machine for producing a filter train, especially for the Manufacture of filters for cigarettes and the like smokable articles, in a schematic side view.
  • This device too Called filter maker, it consists of two main assemblies, one Processing device 1 for fed in an endless filter material strip Filtertow 4 and a processing device 2 for the production of enveloped Filter rods.
  • the processing device 1 has a pair of rollers 3 for continuous Pulling off an endless filter material strip 4 from a bale 6. After removal from bale 6, the filter tow strip passes on his Path to the pair of rollers 3, on which it is guided over a deflection roller 5, two Air nozzles 7 and 8, which are used to spread and loosen the tissue of the Serve filter material strips.
  • the roller pair 3 are followed by two more Roller pairs 9 and 11, between which there is an application device 12 for applying plasticizer to the between the roller pairs 9 and 11 filter material strips 4 which are laid out.
  • All roller pairs 3, 9 and 11 are from a main drive motor 13 via belt drives 13a to c drivable. Instead of a main drive motor 13, one or several separate drives can be provided for the roller pairs.
  • the speed of the pair of rollers 3 is less than that of the pair of rollers 9, so that the roller pairs 3 and 9 form a stretching device.
  • the speed of the pair of rollers 3 can be changed via a gear 14, the Translation can be changed by a controllable adjusting motor 16 can.
  • the speed ratio between the roller pairs 3 and 9 specifies the degree of stretching of the filter material strip 4.
  • the brake rollers 3 are driven. You can also be designed as drag rollers, which due to Frictional conditions act as brake rollers.
  • the application device 12 is on the spread and stretched Filter material strips 4 in a predetermined dosage Plasticizer liquid applied.
  • the prepared filter material strip 4 sprayed with plasticizer arrives over the pair of rollers 11 from the processing device 1 into one Inlet funnel 17 of the processing device 2, in which it summarized and deducted from a bobbin 18 and by means of a gluing device 19 provided with glue wrapping strips 21 is placed.
  • the wrapping strip 21 and the summarized Filter material strips 4 arrive on a format belt 22, both of which Components through a format 23 that wraps the wrapping strip 21 puts the filter material strand around and thereby an endless filter strand 24 forms. This passes through a seam plate 26 in which the adhesive seam is dried.
  • the filter strand 24 by means of a knife apparatus 27 continuously cut filter rods 28, which by an accelerator 29 can be transferred to a spin drum 31 in which they are conveyed in the transverse axial direction of conveyance. From the spin drum 31, the filter rods reach an offshoot belt 32, from which they are one Further processing or temporary storage can be supplied.
  • the plasticizer is supplied to the application device 12 by means of a Dosing pump 33 via a supply line 34 from a plasticizer supply 36th
  • a first and a second measuring device 37 or 38 provided.
  • the first measuring device 37 is a pneumatic one Measuring device for the diameter of the filter strand 24, as in FIG. 2 shown in more detail.
  • the first measuring device 37 is via a Evaluation device 42 with a servo motor 54 of the seam plate 26 connected.
  • the diameter is determined, for example, on the in the applicant's DE 3414247 A1 already mentioned at the beginning way described. The disclosure of this document will hereby made the full content of the subject of the present application.
  • Fig. 2 shows schematically, as with the help of a measuring nozzle 37, the over a flow meter 52 and a control valve 53 with compressed air constant Pressure is supplied from a compressed air connection 55, the diameter is determined. One is also connected to the control valve 53 Overpressure protection 51. The corresponding signal is from the Flow meter 52 passed on to the evaluation arrangement 42.
  • the diameter based on a given relative humidity i.e. a nominal towel moisture
  • Display 56 is displayed.
  • the Diameter control based on a currently measured target value Tow nominal humidity can be operated.
  • a The target value for the nominal towel moisture can be entered and / or entered For example, a previously measured humidity at the entrance of a not filter piecer shown corresponds. From the actual value of the towel moisture on Filtermaker and the target value of the towel moisture at the filter attachment determines the Evaluation arrangement 42 for the diameter to be set on the filter maker the diameter control.
  • an off-line test station 60 for testing the Filter rods 28. It consists of a magazine 61 for filter rods to be tested 28, a diameter measuring arrangement 62, a moisture measuring device based on microwaves 63, an evaluation arrangement 64 and a display 65th
  • Station 60 also determines the actual diameter and the nominal moisture corrected diameter.
  • Fig. 1 a variant is drawn in dashed lines, in which the measuring head 38 ' to determine the Tow moisture is attached where the Tow 4 from Bale 6 is pulled off to the towel moisture before making the To determine filter rods 28.
