Definitions

  • the invention relates to a device for transporting a filter tow from a filter-trough source to a machine for producing filter rods for smoking articles, in particular cigarettes, from the filter tow, with a substantially closed transport channel having an inlet and an outlet and through which the filter tow from the inlet to the outlet is feasible.
  • the invention according to a second aspect relates to a device for producing filter rods for smoking articles, in particular cigarettes, with a Filterertowario, a device for transporting a filter tow according to the first aspect and a device for processing the filter tow for the subsequent production of the filter rods.
  • a device for the preparation of a filter tow is used, which is obtained from a FiltertowISE.
  • the filter tow is usually prepared by stretching and treating with plasticizer, round-shaped and delivered in a desired shape and consistency for further processing to a filter rod machine, which from the processed filter tow by wrapping with a wrapping material makes a filter strand which is finally cut into filter rods of the desired length.
  • the filter trough source is usually designed to receive at least one filter towball from which the filter tow is continuously withdrawn as a strand, strip or tape.
  • the Filtertowario is in direct proximity to the rest of the device or system.
  • the DE 43 00 841 A1 is a transport device of the type mentioned according to the first aspect described, which is able to carry the filter tow over greater distances from a Filterertowttle to the treatment device.
  • the known device has a substantially closed transport channel, through which the filter tow is transported with pneumatic support.
  • the remote arrangement of the filter trough source from the remainder of the apparatus or plant possible due to this known device, provides increased flexibility in designing and dimensioning the factory floor space and also provides easier access to the filter trough source.
  • a device for transporting a filter tow from a filter trough source to a machine for producing filter rods for smoking articles, in particular cigarettes, from the filter tow, with a substantially closed transport channel having an inlet and a Has outlet and through which the filter tow is feasible from the inlet to the outlet which is characterized in that in the region of the inlet of the transport channel a spreading device for spreading the filter tow is provided, through which the filter tow is feasible before it enters or during its entry into the transport channel.
  • the inlet of the transport channel according to the invention a spreader upstream.
  • This spreader through which the filter tow is guided, causes the filter tow to be deployed prior to its entry or entry into the transport channel.
  • “spreading” means transferring the filter tow into a substantially flat and flat band or strip shape and / or increasing the width of the filter tow by fanning, pulling or opening at an angle or transverse to the longitudinal extent and transport direction. With the aid of such a spreading device, it is prevented according to the invention that the filter tow runs in twisted or twisted form through the transport channel. Rather, the inventively provided spreader causes a wrinkle-free or cover-free transport of the filter tow through the transport channel.
  • the invention further allows for a remote placement of the filter tow source from the remainder of the machine without, however, continuing a twist of the filter tow, usually caused by the removal of a filter tow, as an undesirable side effect into the transport channel.
  • a wrinkle-free or cover-free transport of the filter tow is ensured by the transport channel by the spreading device according to the invention, a higher, but at least more uniform product quality can be achieved.
  • the spreader may optionally be located either at a distance upstream of the inlet of the transport channel or substantially directly at the inlet of the transport channel.
  • the spreader device may comprise at least one spreader nozzle.
  • a spreader nozzle is known per se and has traditionally been used prior to delivery to a drafting device located in a conditioning unit or apparatus.
  • the transport of the filter tow takes place within the transport channel with pneumatic support, including a corresponding pneumatic conveyor is to be provided, which has at least one provided at the inlet of the transport channel air inlet nozzle, which takes over the function of an air mover.
  • the air inlet nozzle may expediently be formed by the spreader nozzle, so that transport and spreading is effected only by means of a single nozzle instead of two nozzles connected in series.
  • an additional spreading device can be provided in the region of the outlet of the transport channel, through which the filter tow can be guided during its exit or after its exit from the transport channel.
  • This additional spreading device may preferably be arranged either at a distance downstream from the outlet of the transport channel or substantially directly at the outlet of the transport channel.
  • the additional spreading device may expediently have at least one additional spreader nozzle.
  • the pneumatic conveyor according to the aforementioned embodiment has at least one provided at the outlet of the transport channel air outlet nozzle, which is used as an additional air winder for transport, the air outlet nozzle may conveniently be formed by the additional spreader, which thus in addition to the spreading also still takes over the transport as another function.
  • a further preferred embodiment of the invention is characterized in that the transport channel has a substantially rectangular cross-section with two opposite broad sides and two opposite narrow sides and is formed so that the filter tow is feasible with its broad side substantially along at least one of the two broad sides.
  • the spreading device is aligned with respect to their spreading effect substantially to at least one of the two broad sides.
  • the transport channel have at least one curved portion, which is curved in a plane which is spanned substantially perpendicular to that broad side along which the filter tow is feasible, resulting in a particularly good cornering.
  • a device for producing filter rods for smoking articles, in particular cigarettes, with a filter trough source, a transport device according to the first aspect of the invention discussed above and a device for processing the filter tow for the subsequent production of the filter rods is characterized in that the transport channel essentially from the filter trough source to the apparatus for processing the filter tow leads and the filter trough source is arranged upstream of the spreader.
  • a preferred embodiment of this device is characterized in that the filter tow source is provided for receiving at least one filter towball and is arranged with respect to the spreader device such that the filter tow entering the spreader device can be withdrawn directly from a bale in the filter tow source.
  • the spreading device is arranged substantially above the filter trough source. Such an arrangement enables a particularly simple removal of the filter tow from a bale in the filter trough source.
  • the figure shows a FilterertowISE 2, for example, consist of a container or a receptacle for at least one filter tow 4 or alternatively, for example, may be formed directly from the filter towballs 4.
  • a FilterertowISE 2 for example, consist of a container or a receptacle for at least one filter tow 4 or alternatively, for example, may be formed directly from the filter towballs 4.
  • a filter tow 6 in the form of a strip, ribbon or strand 6 is continuously withdrawn and transported through a substantially closed transport channel 8 to a processing unit 10, which is usually arranged remotely.
  • the filter tow 6 in the processing unit 10 usually passes through various processing devices, which may, for example, in sequence a stretching device for stretching the filter tow 6, a treatment device for spraying the filter tow 6 with a treatment agent and a shaping device for rounding the filter tow 6, but in the Enclosed figure not marked with reference numerals or not at all represent.
  • the transport channel 8 consists in the illustrated embodiment of a pneumatic pipe.
  • an air supply unit 12 is provided which supplies an air inlet nozzle 16 with air via a line 14.
  • the air inlet nozzle 16 is arranged at the inlet 8a of the transport channel 8 and generates an air movement which acts on the filter tow 6 entering the inlet 8a of the transport channel 8 and generates a thrust for the transport of the filter tow 6 through the transport channel 8.
  • the air supply unit 12 supplies via a line 18 an air outlet nozzle 20 with air, which is arranged at the outlet 8b of the transport channel 8 and acts on the outlet from the outlet 8b filter tow 6 in the same way as air winder as the air inlet nozzle sixteenth
  • a first spreader nozzle 22 is arranged, which is a known spreader nozzle and which is supplied by the air supply unit 12 via a line 24 with air.
  • the filter tow 6 is initially guided in the illustrated embodiment through the spreader nozzle 22, before it is then drawn through the air inlet nozzle 16 into the inlet 8a of the transport channel 8.
  • the spreader nozzle 22 is arranged substantially vertically above the filter tow source 2, as shown in the figure.
  • the filter tow 6 is spread to a substantially flat and planar strip.
  • “spreading” is understood to mean transferring the filter tow 6 into a substantially flat and flat ribbon or strip shape and / or increasing the width of the filter tow 6 by pulling, fanning or opening. After exiting the spreader 22 passes Thus, the filter tow 6 as in the figure, not shown, substantially flat and flat strip through the air inlet nozzle 16 and the inlet 8a in the transport channel eighth
  • the filter tow 6 is often subjected to a twist or twist, which is usually caused by zig-zag peeling off of the filter towbale 4.
  • the twist or twist in the filter tow 6 is eliminated or prevented by the filter tow 6 emerging as a substantially flat and flat strip from the spreader nozzle 22 and in this shape is introduced through the air inlet nozzle 16 into the inlet 8a of the transport channel 8.
  • the spreader nozzle 22 enables a wrinkle-free or cover-free transport of the filter tow 6 through the transport channel 8.
  • the filter tow 6 of the transport channel 8 should preferably be formed as a pipe having a rectangular cross-section with two opposite broad sides and two opposite narrow sides, wherein the filter tow 6 with its flat broad side substantially along at least one of the two Broadsides is performed.
  • This particular embodiment of the transport channel 8 can not be deduced from the figure, which shows the transport channel 8 only with a view of one of its two narrow sides.
  • the filter tow 6 is usually substantially flat on its inside wall on one of the two broad sides of the transport channel 8 during its transport.
  • the transport channel 8 has a curved portion, as it is indicated in the figure by the reference numeral "8c", this is curved in a plane which is spanned substantially perpendicular to that broadside, along which guided the filter tow 6 becomes.
