Definitions
- the invention relates to a method for the continuous compression of a moving stream onto filter material, in particular from fibers of cellulose acetate, the cross section of which is reduced after the processing of the filter material, a pressing means exerting pressure on at least one surface of the stream of filter material during compression.
- the invention also relates to a device for the continuous compression of a moving stream of filter material, in particular of fibers made of cellulose acetate, the cross section of which is reduced after the filter material has been processed, with a pressing means for exerting a compression pressure on at least one surface of the stream.
- Methods and devices of the type mentioned are known and are widely used in the tobacco processing industry, e.g. B.
- the processing of the filter material takes place essentially in such a way that in a processing device a fabric strip z. B. from cellulose acetate fibers a stock, z. B. a bale, is continuously removed that the fibers are spread transversely to their direction of movement and thereby separated that the fibers with a solvent such. B. triacetin are sprayed, whereby they are dissolved and can network with each other in the course of further processing, whereupon the fibers are gathered and fed to the filter rod machine.
- the above processing steps are carried out while the fiber material, also called filter tow, continuously runs through the individual processing stations, of which only the most important are listed.
- the gathered stream of filter material is compressed on the filter strand machine until it has reached approximately strand diameter. Then it is continuously wrapped in a so-called format by a wrapping strip, usually made of so-called filter paper, which can be air-permeable or air-impermeable.
- a wrapping strip usually made of so-called filter paper, which can be air-permeable or air-impermeable.
- One with glue, e.g. B. with so-called hot-melt adhesive edge forms an adhesive seam that is cooled when using hot-melt adhesive.
- the continuously formed filter strand made of filter material encased by the wrapping strip is then cut into individual filter rods by a revolving knife apparatus, the knife of which is moved along with the filter strand at the time of cutting, which are conveyed away by a so-called offshoot.
- the strand of filter material is compressed by a so-called finger, which is placed in front of the format and which presses on the stream of filter material to be compressed from above. It is arranged in such a way that its distance from a belt that conveys the filter flow becomes smaller and smaller until it finally reaches the height of a strand. Because of the considerable resistance that filter material (e.g.
- filter tow made of cellulose acetate fibers
- considerable pressure is exerted on the sliding surface of the finger, which can lead to temperatures in modern high-speed machines that are above the melting point of the filter material. Partial melting of the surface of a filter strand is usually undesirable, since it can negatively influence the flow properties of the filter rods.
- the object on which the invention is based is to avoid an undesirable increase in temperature of the filter material when it is compressed. According to the invention, this is achieved in that the pressing means is made to vibrate at least in the area of the surface.
- the frequencies of the vibrations into which the pressing agent, i. H. at least the surface of which is displaced can in the ultrasound range, for. B. are in the range between 5 and 50 kilohertz (kHz).
- the most favorable frequency for a particular application depends on the lubricity of the pressing agent and the filter material to be compressed and can - at least approximately - be easily determined experimentally.
- the most favorable amplitudes can also be determined experimentally, at least approximately.
- the directions of vibration can run perpendicular to the direction of movement of the filter material, ie vertically if the direction of movement of the filter material is horizontal.
- An advantageous development of the invention consists in providing vibrations which run entirely or at least with a directional component in the direction of movement of the filter material.
- the compressed stream of filter material can, after reaching its final cross-section to form a filter strand, be continuously glued on, preferably at one edge Wrapping paper strips are wrapped.
- the stream of filter material in particular a tissue made of cellulose acetate (filter tow), can be continuously taken from a supply, stretched and spread before compacting, after which the fibers are sprayed with plasticizer or another solvent and then gathered and compacted.
- the device mentioned at the outset is characterized by a vibration exciter which is connected to the pressing means and which vibrates the pressing means at least in the region of the current surface.
- the vibration exciter advantageously sets the pressing means in vibrations whose frequencies are in the ultrasound range.
- the frequency range can be between 5 and 50 kilohertz (kHz), that in the amplitude range between 3 and 55 micrometers ( ⁇ m).
- vibrations of other frequencies and amplitudes are possible.
- suitable or optimal frequencies and amplitudes can easily be determined experimentally if necessary.
- a further advantageous embodiment of the invention consists in giving the vibrations at least one component in the direction of movement of the stream of filter material to be compressed or in letting them run entirely in this direction.
- the vibration conditions can be improved by an extension surface in the area of the pressing means.
- the surface of the press medium along which the strand of filter material slides is subject to high wear. It is therefore preferably made of a very wear-resistant material that is sufficiently slippery. A surface made of high-performance steel, which was produced using the powder metallurgy process, has proven to be suitable for this.
- the compression device in the direction of movement of the flow of filter material, can be followed by a device for continuously enveloping the strip of filter material compressed into a strand with a wrapping paper strip which is preferably glued in the region of an edge in the direction of movement.
- the compacting device can be preceded by a preparation arrangement for the filter material, with a removal device for the continuous removal of a fabric strip from fibers made of filter material, preferably cellulose acetate, with a spreading device for the fibers and with an application device for plasticizers or similar solvents.
- the compression device according to the invention has the advantage that, due to the reduced friction caused by the vibrations, an increase in the temperatures up to critical values at which melting of the surface of the filter material is to be feared is avoided. In addition, the energy requirement for compression is lower than in the previous devices.
- FIG. 1 shows a processing arrangement for strip-shaped cellulose acetate with a directly coupled strand machine for forming a filter strand
- Figure 2 details of a pressing means for a stream of filter material with a vibration exciter on an enlarged scale.
- FIG. 1 shows two main assemblies of an arrangement for the production of filter rods, namely a preparation arrangement 1 for filter fabric fed in an endless strip, and a filter rod machine 2 for the production of coated filter rods.
- the processing arrangement 1 z. B. of the type known in the tobacco processing industry AF 1 or AF 2 of the applicant has a pair of rollers 3 for the continuous removal of an endless strip of fabric 4, preferably from cellulose acetate fibers from a bale 6. Before the fabric strip 4 (also called filter tow) reaches the pair of rollers 3, it passes through two air nozzles 7 and 8, which serve to loosen the fabric.
- the roller pair 3 is followed by two further roller pairs 9 and 11, between which there is a spray device 12 for applying plasticizer 13 to the fabric strips 4 which are pulled apart between the roller pairs 9 and 11.
- a spray device 12 for applying plasticizer 13 to the fabric strips 4 which are pulled apart between the roller pairs 9 and 11.
- All pairs of rollers 3, 9 and 11 can be driven by a main drive motor 14.
- the speed of the pair of rollers 3 is lower than that of the pair of rollers 9 and can be changed via a gear 16, the translation of which can be changed by a controllable adjusting motor 17.
- the spraying device consists of a container 18 for receiving softening agent liquid 13, into which a removal roller 21, which can be driven by a drive motor 19, is immersed.
- a rotating brush roller 22 continuously removes plasticizer liquid from the periphery of the removal roller 21 and hurls it against the threads of the fabric strip 4 which is pulled apart between the roller pairs 9 and 11 2 z.
- the glue of gluing device 26 serves to fix the filter fiber bundle (filter tow) within the wrapping strip in order to prevent it from slipping during later processing steps.
- the wrapping paper strip 27 and the fabric strand 4 arrive on a format belt 28, which guides both components through a format 29, which continuously wraps the wrapping paper strip 27 around the fabric strand and thereby forms an endless filter strand 31.
- Another gluing device 20, e.g. B. a heated glue nozzle gives glue, z. B. so-called hot melt adhesive, from one edge of the strip 27.
- the edge which overlaps when the strand 31 is formed forms an adhesive seam which is cooled by a so-called seam strip 32, so that the hot-melt adhesive quickly solidifies.
- a knife apparatus 33 with a revolving knife cuts off continuous filter rods 34, which are transferred from troughs of a cam accelerator 36 into troughs of a trough drum 37 and are delivered to a conveyor belt 38.
- the finger 25 represents a pressing means that continuously reduces the flow 4 of filter material from a larger cross-section to a smaller cross-section, in which it has approximately strand dimensions.
- the finger 25 is set in vibration by a vibration exciter 41, so that its power is applied Filter material pressing surface vibrates.
- the finger 25 representing a pressing means is shown enlarged. It presses with its surface 42 onto the surface of the stream 43 of processed filter material, which is conveyed together with the wrapping paper strip 27 by the format belt 28 from the inlet funnel 23 in the direction of arrow 44 to the format 29. During the conveyance, the height of the filter material is reduced from h1 to h2, which increases the compression of the filter tow and thus the friction.
- the surface 42 of the finger 25 is curved. The curvature increases in the direction of arrow 44 in order to give the filter material an increasingly round shape.
- an oscillator 46 which excites a vibrator 47 to carry out vibrations in the ultrasonic range.
- Magnetostrictive excitation is shown, other types, e.g. piezoelectric excitation are also conceivable.
- the excitation forms standing ultrasonic waves with a wavelength ⁇ in the vibrator 47, which are transmitted through the contact surface 51 to a reinforcing booster 48 and to the finger 25.
- the vibrator 47 has a node 49.
- the booster 48 has a node 52.
- the amplitude of the standing ultrasound waves, which form before the arrangement, is almost zero, so these points can be used to fasten the device shown be used on the machine.
- 57 with extension surfaces of the pressing means 25 are designated.
- the distance L1 from surface 51 to surface 42 is advantageously as large as the wavelength ⁇ of the ultrasonic vibrations.
- the distance l ⁇ is equal to m x ⁇ / 4, where m is an integer, preferably an odd number greater than 1.
- the oscillation frequency of the vibrator 47 can be between 5 and 55 kHz
- the amplitude is between 3 and 55 ⁇ m.
- Favorable values for frequencies and amplitude can be determined experimentally.
- the vibrator 47 performs vertical oscillations / vibrations according to arrow 53.
- a horizontal vibration according to arrow 54 can be achieved if a vibrator, not shown, engages the finger 25 at 56. This oscillation then runs in accordance with the conveying direction 44 of the stream 43 made of filter material.
- a vibrator (not shown) to engage the finger 25 obliquely, so that the vibrations have a component in the vertical direction 53 and a component in the horizontal direction 54.
