Definitions

  • the invention relates to a method for processing a strip of filter material of the tobacco-processing industry, in particular filter tow, which is conveyed along a conveying path, wherein in a job path by means of an applicator a, preferably liquid, additive is applied to the strip.
  • a, preferably liquid, additive is applied to the strip.
  • a strip of filter material in particular filter tow, of interconnected fibers, such as cellulose acetate, continuously withdrawn from a stock, eg from a bale, spread, stretched and with a plasticizer, such as triacetin, sprayed, laterally shirred, fed to a blown air nozzle and then fed to a hopper, fed from which the processed and compressed filter strip a filter rod machine becomes.
  • a plasticizer such as triacetin
  • the strip formed into a filter strand is enveloped continuously with a wrapping material strip, with further compression, so that filter rods are cut off from the wrapped filter strand.
  • a generic device or arrangement for processing a filter material strip is made EP-B-0 654 224 known.
  • Proven processing equipment of the type described above are built and sold under the name AF2, AF3 and AF4 by the patent applicant.
  • Proven filter rod machines of the type described are built and sold under the name KDF2, KDF3 and KDF4 by the patent applicant.
  • DE-A-100 31 848 and EP-A-1 325 685 describe further devices for producing filter rods for rod-shaped articles of the tobacco-processing industry, in which filter tow strips are passed along a stretching line, application line and gathering line.
  • Triacetin deposits in the interior of the housing of an application device or spraying chamber in the form of mist.
  • the Triacetinnebel can thereby emerge from the inlet and outlet columns of the housing and wet in the area of the order range filter material strips leading areas in the drafting system.
  • the promotion of the filter tuck is interrupted, whereby the stopped TowstMail in the order range due to the deposition in the spray chamber or outside the spray chamber with triacetin in contact.
  • the tow strip After a period of a few minutes, for example 10 minutes, the tow strip, which comes in contact with triacetin, begins to dissolve. In a subsequent start of production or machine start, it may therefore come to demolish the tow.
  • a filter tow is prepared and provided by means of a Besprühvorraum with a plasticizer. Subsequently, the plasticized filter tow is formed into a filter strand and wrapped. Thereafter, the formed filter strand is cut into filter rods, which are transferred to a conveyor drum, wherein the filter rods are transferred from a longitudinal axial promotion in a transverse axial promotion on the conveyor drum.
  • GB-2 078 559 discloses a process for applying a plasticizer to a filter tow of the tobacco processing industry. Upon interruption of the promotion of the filter tow strip and the plasticizer supply, the plasticizer is discharged from the receiving area of the spray device, so that when restarting the Filtertowender the plasticizer supply is first resumed with a plasticizer excess, and then continue the plasticizer supply.
  • the object of the present invention is to improve the treatment process, in particular after a production stop or an interruption, wherein it should be possible that after a business interruption the production can be started trouble-free in the simplest possible way.
  • This object is achieved by a method for processing a strip of filter material of the tobacco-processing industry, in particular filter tow, which is conveyed along a conveyor line, wherein in areferssumble by means of a applicator a, preferably liquid, additive is applied to the strip, which further developed in that, during production stoppage, the promotion of the strip and the application of the additive are discontinued, during the production stoppage additive in the area or in the applicator is picked up by a portion of the stopped strip and, during the production stop, after a predetermined period of time, the strip is carried on.
  • a, preferably liquid, additive is applied to the strip, which further developed in that, during production stoppage, the promotion of the strip and the application of the additive are discontinued, during the production stoppage additive in the area or in the applicator is picked up by a portion of the stopped strip and, during the production stop, after a predetermined period of time, the strip is carried on.
  • the invention is based on the idea that after initiation or during a production stoppage of the strip or its section in the region of the order line the additive, the leading to the conveyor organs or in the spray chamber or applicator device and the filter material strips facilities, For example, attaches guide surfaces or the like, during a waiting time and at standstill of the promotion of the strip receives.
  • the strip is conveyed further, so that the filter material strip leading devices or parts are freed in the range ofratisrange from the deposits of the additive, whereby after the promotion of the impregnated with additive strip portion strips the leading institutions free of that Additive (triacetin) are.
  • the post-conveyed strip can remain in the region of the application line without any further additive, for example triacetin, which could dissolve this strip section being taken up to a considerable extent by this strip section.
  • the portion of the strip which receives or has taken up additive is conveyed from the area of the application device or the order section into an additive-free area.
  • the strip of material soaked in triacetin or the corresponding section is moved past the format outlet of the strand forming unit or strand production unit, so that a dry filter strip section is located in the region of the application line during production stoppage.
  • a further improvement is achieved in that during the promotion of the strip after the predetermined period of time, the strip entering the application line is not stretched during or during its delivery, so that any triacetin remaining in the application device does not dissolve the denser tow strip.
  • the strip is conveyed during conveying or during conveying after the determined period of time (waiting time) with a width in the area of the application device or order path which is smaller than the width of the strip during the current processing process is.
  • the conveyance of the strip is interrupted, so that a treatment device can stand idle for a long time, for example for maintenance purposes or the like, without the filter material strip having to be handled manually by the operating personnel.
  • Another solution to the above-mentioned method for preparing a strip of filter material of the tobacco processing industry is that in a production stop the promotion of the strip and the order of the additive are interrupted, wherein after the production stop, the strip or a portion of the strip in the area or moved in the applicator or the applicator and the strip are moved relative to each other.
  • the invention is based on the idea that by the movement of the strip or the strip portion in the order range at standstill of the production of the filter tow at the corresponding contact points with the filter material strips leading institutions or institutions on which has deposited triacetin, a bond and a resolution of the strip can be avoided because the sweeping of the contacting strip portion of the additive is uniformly absorbed on a larger area of the section.
  • the strip is moved in the region of the application path relative to the stationary application device.
  • the applicator is moved with respect to the stopped strip.
  • the application device is displaced back and forth along the stationary strip and / or transversely to the stationary strip, so that the additive or its deposits at the contact points with the strip also over a larger strip area, in particular evenly received or distributed.
  • the strip or the strip section is moved in an oscillating manner, in particular in the region of the application path.
  • the strip or the strip portion is oscillated in and against the conveying direction or production conveying direction of the strip.
  • the strip can be moved in an oscillating manner transversely to the conveying direction or production conveying direction of the strip.
  • the movement of the strip in the region of the application path can take place according to a predetermined movement pattern.
  • the amplitudes of the oscillatory movement can be designed to be variable depending on the requirement. It is crucial that the filter material strip at the contact points, for example on the scraper strips, rollers or base plates or the like, is reciprocated to avoid sticking of the strip by the recorded triacetin during the stoppage.
  • the oscillating movement of the strip is carried out for a predetermined period of time. With a production interruption of the treatment process becomes thereby the strip moves, with no production at the same time, ie no application of additive by an applicator member on the strip.
  • the oscillating movement of the strip is repeated at predetermined time intervals. For example, after a break of 10 to 15 minutes, the strip is moved over the contact points within the application path.
  • the oscillating movement of the strip within the application path can be achieved by correspondingly rotating the pairs of rollers back and forth before and after the application path, thereby achieving the oscillating movement in or against the production conveying direction of the strip.
  • a movement of the strip transversely to the production conveying direction can be realized in that the pairs of rollers are moved back and forth parallel to their axis of rotation before and after the application path.
  • the strip or the strip portion in the area or in the application device with a gaseous medium, in particular air is applied.
  • a gaseous medium in particular air
  • the strip is separated from the surface or from the contact points within the application device or the application path and / or kept in motion to prevent sticking to the usual contact points.
  • this can be done by appropriate nozzles along the order path and along the strip are arranged laterally.
  • nozzles may be provided in the rollers to the Supply air to the strip or strip section in the area of the application line.
  • the gaseous medium is passed via nozzles on the strip or strip portion accordingly.
  • Another solution of the above-mentioned method is also that is interrupted at the initiation of a production stop the order of the additive and the untreated strip is further promoted for a predetermined period of time, so that deposits of the additive are removed from thesecondsumble and after a predetermined period of time Promotion of the strip upon reaching a predetermined degree of cleaning of the job path and the applicator is terminated.
  • the applicator or the filter material leading and processing facilities in the field ofratis be cleaned by the deposits of the additive that while maintaining the promotion of the strip of the order of the additive is terminated first, whereby the deposits at the contact points of the dry , untreated strips are picked up and removed from the job path. After a predetermined period of time, the delivery of the strip is then also terminated when a predetermined degree of cleaning of the application path and in the application device is reached.
  • the production stop be initiated outside the application device as a function of a state of a device, for example a filter rod magazine.
  • the proposed solutions according to the invention ensure that the application device or the filter material strips leading institutions or organs of a job or Aufbreitungsvorraum be cleaned at initiation or after a production stop of the treatment process of deposits of the additive, which due to the automatic execution of the cleaning process is an improved Handling of the treatment process or processing equipment results.
