Definitions
- the invention relates to a device for producing a filter cable according to the preamble of patent claim 1.
- Such a device is already known from European Patent EP 0 128 031 B1.
- the cellulose acetate cable is fed via spreader nozzles, stretching rollers and deflecting rollers to the inlet nozzle of an inlet filler, which introduces the cellulose acetate cable into a shaped cable sleeve.
- an inlet funnel is connected between the inlet nozzle and the inlet nozzle.
- an additive nozzle mouths for adding an additive to the cellulose acetate cable m of the inlet nozzle FIGGS. 1 and 4
- the additive nozzle mouths in the mouth funnel (FIG. 6).
- a disadvantage of the known device is that no device for producing a discontinuous multi-component strand is provided.
- No. 3,847,064 describes a device in which a solid is fed discontinuously to a filter tow, a movable mandrel acts as an additive nozzle.
- the disadvantage of this method is that it "fails" at high speeds.
- a method for producing multiple filters for tobacco smoke in which a foamed thermoplastic material is extruded and a filter rod shape is made in a manner known per se by means of an extruder head and an extruder.
- a pulsed additive is introduced into the extrudate, which displaces the foamed extrudate at the point of introduction and thus forms alternating areas of additive and foam in the filter rod.
- the object of the invention is also the supply of fixed Addit ⁇ - ven easy to perceive afford, especially at high transport speeds.
- Another object of the invention is to provide a device which makes it possible to ensure a discontinuous supply of solids, the additive being “injected” into the central or core region of the filter, so to speak, and thereby the boundary layer between the core and the jacket material is as low as possible.
- an additive nozzle runs in the direction of the filter cable through the inlet nozzle and through the filler funnel to the filler where it mouths and thus an additive can feed directly into the filter cable.
- the transport speed of the filter cable is advantageously chosen to be approximately 1.2 to 2 times, preferably 1.5 times as large as the transport speed of the additive portions. This leads to an extremely even additive distribution today's high production speeds.
- Both solid, fibrous or fan-shaped and capsule-shaped substances come into question as solid additives.
- selective sorbents such as activated carbon, organic acids, encapsulated flavors or decomposable materials such as cellulose esters or cellulose fiber form are used.
- shipping ⁇ hene flachenformige materials such as cellulose ( "Papierschnip- was") can be used.
- Figure 1 is a schematic representation of the inventive device
- Figure 2 shows a section of the inventive device according to Figure 1;
- Figure 3 shows a second embodiment of the invention for the
- FIGS 4a and 4b show modifications of the device of Figure 3;
- Figure 5 shows an embodiment similar to Figure 3, but with an oscillating conveyor
- FIG. 6 shows a further embodiment of the invention.
- FIG. 7 shows a section A-A from FIG. 6.
- FIG. 1 shows a filter cable 1, expediently made of cellulose acetate, which is led through various stations to a format chamber 21, from which it emerges as a filter strand 22. It is drawn from a bale 24 by two pairs of stretching rollers 6, 7 and 8, 9, for which purpose the two pairs of stretching rollers 6, 7 and 8, 9 are driven.
- the filter cable 1 is pulled through a first spreader gland 2 and a second spreader terduse 3, which are of a known type and which expand the compressed filter cable 1. Between the first spreader nozzle 2 and the second spreader nozzle 3, the traction path of the filter cable 1 is steered by approximately 135 °, for which purpose the cellulose acetate cable is pulled over a knee 23.
- a brake roller pair 4, 5 is arranged behind the second spreader nozzle 3 and in front of the first pair of stretching rollers 6, 7, which serves to even out the speed at which the filter cable 1 is transported.
- the following elements are arranged in the following sequence in the direction of transport behind the second pair of stretching rollers 8, 9: firstly a third spreader nozzle 10, then a spray box 11, a pair of deflecting rollers 12, 13 and finally an inlet nozzle 14.
- the outlet opening of the inlet nozzle 14 mouths an emptying funnel 15, the outlet opening of which in turn ends in an emptying nozzle 16.
- the Emvierfmger 16 is part of a format chamber 21, which ultimately produces the filter rod 22.
- a format belt 17 is arranged under the format chamber 21 and serves to transport the filter strand 22 at the desired speed.
- An additive nozzle 20 is inserted into the inlet nozzle 14, which can be better seen in FIG. 2.
- the additive nozzle 20 is supplied with the additive from an additive container 18 via an additive pump 19 and an additive line 25.
- Figure 2 shows an enlarged schematic section through the
- Inlet nozzle 14 is guided and pressurized with air or gas, which results in an expansion of the cellulose acetate.
- the cellulose acetate is expanded essentially in the emptying funnel 15 and continues in the emptying funnel 16.
- the additive nozzle 20 is now guided through the inlet nozzle 14 and through the inlet funnel 15 to m the inlet nozzle 16, by which it mouths and thus allows the expanded cellulose acetate cable to enter directly at a speed v.
- the transport speed of the filter cable 1 is indicated by Vi and the relationship between the two speeds v and v 2 is expediently as follows: Vi / v? > 1.5.
- the transport speed of the filter cable 1 is therefore always greater than that of the additive, which results in a very uniform distribution of the additive cellulose acetate cable.
- the device according to FIG. 3 corresponds essentially to the device shown in FIG. 1 and described in connection with this figure, although the solid additive is not supplied by a pump, for example from below, but by gravity from above. As far as the parts match, they are provided with the same reference numerals.
- FIG. 3 shows the filter cable 1, which is guided over the deflecting roller pair 12, 13 through the inlet nozzle 14, the inlet funnel 15 and from this the inlet inlet 16.
- the format chamber 21, under which the format tape 17 is arranged, is connected to the feeder 16 in order to further transport the filter strand 22.
- a number of bores 29 are provided in the emulator 16 which serve to discharge the transport gas for the solid additive to the outside.
- the additive nozzle 20 extends through the inlet nozzle 14, the discharge funnel 15 and the
- Emertonfmger 16 However, your feed end is not on a pump connected, but leads via the additive line 25 to the outside to a funnel 30 which contains the solid additive 33 and feeds it by gravity, supported by transport gas.
- a gas line 31 guides the funnel 30 from above and ends with the mouth of the additive line 25 with a narrowed section 32 which forms a capillary.
- the solid additive with the aid of the transport gas as a gas-additive mixture passes through the additive line 25 and the additive nozzle 20 through the center of the filter cable 1, the individual fibers of which carry the solid additive material out of the gas-additive flow transport direction, while the transport gas passes through the holes 29 can emerge from the Emlauffmger 16.
- the solid additive can have a grain size between about 10 and 400 esh (ASTM Ell-61 USA standard) i.e. have a grain diameter of approximately 40 ⁇ m to 2 mm or be fibrous.
- the speed v 2 of the filter cable 1 in the emffmger 16 should be selected approximately 1.2 to 2 times, preferably 1.5 times as large as the speed v 2 of the gas-additive mixture emerging from the narrow pipeline become.
- the gas line 31 is not guided from the top of the funnel 30, but instead, with its narrowed section 32, mends a knee of the additive line 25, which connects the additive line 25 to the additive nozzle 20. In this way, a shorter gas line than in the embodiment according to FIG. 3 is required.
- FIG. 4b an additional line is attached to the funnel 30, which draws the solid additive 33 out of a storage vessel and supplies it to the additive line 25 and thus to the additive nozzle 20.
- FIG. 5 shows a further embodiment which is modified in the area of the funnel 30.
- the gas line 31 is guided from above the funnel 30.
- the narrowed section 32 is angled to allow the solid additive to be fed centrally or centrally to the funnel 30.
- the solid additive is supplied via a vibrating conveyor 34 from a funnel 35 via a horizontal vibrating line 36.
- the vibrating conveyor 34 causes a solid additive which tends to stick together to be continuously shaken and thus does not stick together on the transport path to the additive nozzle 20.
- FIG. 6 shows a further embodiment of the invention, in which, as in the embodiment according to FIGS. 1 and 3, the filter cable 1, via a deflecting roller pair 12, 13, through an inlet nozzle 14 and an emptying funnel 15 m, an emptying device 16, from which it is passed m arrives in the format chamber 21, which it leaves as a filter strand 22 with discontinuously embedded portions 28 of a solid additive 33.
- the same parts are provided with the same reference numerals. It can thus be seen that the portions 28 of the solid additive 33 are fed discontinuously via the additive line 25 through the inlet nozzle 14.
- the transport gas carried along for this purpose in turn exits through the bores 29 in the embosser 16.
- the procedure is such that the solid additive 33 is dispensed from a funnel 30 onto a double tooth 26.
- the double toothed belt 26 runs around a first toothed pulley 38 and around a second toothed pulley 39, the usual first tooth being located on its underside.
- One of the two toothed disks 38 or 39 is provided with a drive, not shown.
- At the Top of the Doppel leopard ⁇ emens 26 are also provided teeth, which form tooth gaps 40 there, m the solid additive 33 falls and is transported away from the funnel 30 to the additive line 25 when the toothed disks 38 and 39 are rotated.
- the gaps 40 of the double tooth 26 serve for portioning the solid additive 33 m in such a way that portions 28 are formed corresponding to the width of the double toothed belt 26, which are transported away by gas pulses from the tooth gaps 40, the additive line 25, as shown in FIG.
- the double tooth learning 26 is provided in the area of the funnel 30 and over its entire width with a covering 27 which forms a laterally closed chamber or a channel.
- the holes 41 of which are arranged at a distance from the tooth spaces 40 and which each block or release the supply of compressed gas to the gas line 31, so that compressed gas is always in synchronism with the movement of the double toothed belt 26 to the tooth spaces 40 is placed and thereby the portions 28 of the solid additive present in the tooth gaps 40 on the additive line 25 can inject the additive line 25 from the respective tooth gap 40 m.
- the additive portions 28 produced in this way or in another manner familiar to the person skilled in the art, the diameters of which are smaller than the diameter of the filter strand 22, so that the portions 28 can be embedded in the material of the filter strand 22 and can be completely enclosed by the latter, are caused by gas or through another gas suitable for transporting the portions 28 through the additive line 25 m to the feed hopper 15.
- a gas for example, nitrogen comes into question.
- the portions 28 When emerging from the discharge funnel, the portions 28 are injected into the filter strand 22 in such a way that they are placed centrally in the filter strand 22.
- the transport speed for the additive portions 28 the The distance between the portions 28 in the filter strand 22 can be set, the upper limit for the transport speed being given when the individual portions 28 in the filter strand 22 abut one another in the axial direction.
