Abstract

The method involves applying a fluid additive on a strip (2) e.g. filter tow strip, in an application section by an application device. The conveying of the strip and the application of the additive are interrupted during a production stop, and the additive in the area or in the application device is received from a section of the stopped strip and is further-conveyed after a pre-determined time period of the strip.

Description

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.

For the production of filter rods for the tobacco processing industry, a strip of filter material, in particular filter tow, of interconnected fibers, such as cellulose acetate, continuously withdrawn from a stock, eg from a bale, spread, stretched and with a plasticizer, such as triacetin, sprayed, laterally shirred, fed to a blown air nozzle and then fed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. In a filter rod machine, 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.

Furthermore, in 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.

During the production or preparation of a filter tow strip, 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.

In an interruption of the treatment process, ie at a machine stop, for example, to carry out maintenance, the promotion of the filter tuck is interrupted, whereby the stopped Towstreifen in the order range due to the deposition in the spray chamber or outside the spray chamber with triacetin in contact.

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.

Based on this prior art, 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 production in the simplest possible way can be started trouble-free ,

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 a Auftragsstrecke by means of a applicator a, preferably liquid, additive is applied to the strip, which further developed is that in a production stop the promotion of the strip and the order of the additive are interrupted, additive in the area or in the applicator is taken up by a portion of the stopped strip and after a predetermined period of the strip is further promoted.

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, guide surfaces or the like accumulates during a waiting time and at standstill of the promotion of the strip.

After a predetermined period of time, for example 3 to 5 minutes, the strip is conveyed further, so that the filter material strip leading devices or parts are freed in the range of Auftragsstrecke from the deposits of the additive, whereby after the promotion of the impregnated with additive strip portion strips the leading institutions free of the additive (triacetin). After the conveying out or further conveying of the impregnated strip section, 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.

Thus, according to the invention, it is no longer necessary for the operating personnel, for example, to open the hood of a spraying chamber and to remove the strip from the chamber in order to prevent the absorption of triacetin by the strip of filter material. According to the invention, an automatic cleaning of additive deposits in the area of the application line and the facilities provided with additive or conveying elements of a filter processing machine, for example by deposits, is thereby achieved. Overall, this results in a much better and more effective handling of such treatment equipment, since the cleaning is carried out without further manual handling.

Furthermore, after the removal of triacetin at standstill of the production is achieved that when restarting the filter production or at production production of the filter material strip Can be used without further handling for production. As a result, an automatic commissioning of a production machine is realized.

For this purpose, it is further provided that 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. For example, 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.

According to a preferred embodiment of the method, it is provided that 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. This ensures that the untreated Towstreifen runs narrower through the application path or spraying zone of the applicator, whereby a dissolution of the incoming fresh Towstrip is avoided by the removal of Triacetinablagerung from the field of Auftragsstrecke.

Moreover, after a second predetermined period of time, 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.

Here, 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. According to this inventive idea, the strip is moved in the region of the application path relative to the stationary application device.

In an alternative embodiment, without limiting the general inventive concept, the applicator is moved with respect to the stopped strip. In this case, 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.

In the context of the invention, it is also conceivable that the application device and the strip are moved simultaneously relative to each other in order to transfer the deposits of the additive to the strip.

According to a preferred embodiment, it is provided that the strip or the strip section is moved in an oscillating manner, in particular in the region of the application path.

For this purpose, the strip or the strip portion is oscillated in and against the conveying direction or production conveying direction of the strip. In addition, in a further or alternative embodiment, 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. In this case, 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.

Furthermore, it is advantageous if 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.

In a preferred embodiment, it is also advantageous that 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.

In an alternative embodiment of the movement of the strip is provided that the strip or the strip portion in the area or in the application device with a gaseous medium, in particular air, is acted upon. By applying the strip in the region of the order path with air via corresponding blown air nozzles, 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. For example, this can be done by appropriate nozzles along the order path and along the strip are arranged laterally. In addition, nozzles may be provided in the rollers to the Supply air to the strip or strip section in the area of the application line.

For this purpose, it is further proposed that the gaseous medium is passed via nozzles on the strip or strip portion accordingly.

Another solution of the above-mentioned method is also that the initiation of a production stop the order of the additive is interrupted and the strip is further promoted for a predetermined period of time.

According to this concept of the invention, the applicator or the filter material leading and processing facilities in the field of Auftragsstrecke 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.

In addition, it is favorable in a development that when the production stop is initiated, the stretching of the strip in the stretching section, which is arranged upstream of the order section, is terminated. As a result, the fibers of the strip of filter material are no longer separated, whereby an improved cleaning and removal of Triacetinablagerungen be achieved at the contact-leading facilities in the field of Auftragsstrecke.

Furthermore, according to an advantageous embodiment, it is proposed that 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 Aufbreitungsvorrichtung 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.

In the following figures, identical or similar elements or corresponding parts are provided with the same reference numerals, so that a corresponding renewed idea is dispensed with.

Referring to Fig. 1, the processing means for a bale strip 2 of filter tow, e.g. Cellulose acetate, with continuous fibers following main assemblies that passes through the strip 2 below, on: a withdrawal line 3, a Vorreckstrecke 4, a stretching line 6, a Auftragsstrecke 7, a Raffstrecke 8 and a feed path 9. The feed line 9 is used to feed a strip section an inlet device of a filter rod machine 11 shown schematically, for example Known from the tobacco processing industry known type KDF2, KDF3 or KDF4 the patent applicant.

The withdrawal line 3, in which the withdrawn from a bale not shown here filter material strip 2 is conveyed, has a spreader nozzle 16, which receives compressed air from a compressed air source. The compressed air serves to spread the funded filter fabric In this section. A controllable spreader nozzle is eg in the US-A-4,259,769 described.

Via a deflection plate 19 of the filter tow 2 passes into the pre-stretch 4, on the one hand by a pair of rollers 21 with the rollers 22, 23, on the other hand by a pair of rollers 24 with motor-driven rollers 26, 27 is limited. The rollers 22, 23 are towed from the tow strip, i. they run empty with more or less resistance. If necessary, they can be powered by a motor. They can also be pressed in a manner known per se with controllable force against each other. In the Vorreckstrecke 4, in which the strip portion is conveyed obliquely down, the filter tow 2 is vorgereckt.

To the pair of rollers 24, the stretching line 6 connects, in which the filter tow 2 is conveyed vertically or with a vertical component from top to bottom. At the end of the stretching section 6 is another pair of rollers 39 of motor-driven rollers 41, 42 whose peripheral speeds are slightly greater than the peripheral speeds of the rollers 26, 27, so that the elastic filter tow 2 is defined stretched. The roller pairs 24 and 39 thus form the actual stretching device. The rollers 26 and 41 have a rigid, grooved surface, each contacting a compliant surface of the rollers 27 and 42, respectively. Such roll configurations are known from the aforementioned filter tup processing devices AF 2, AF 3 and AF 4 of the applicant and, for example, in US-A-3,317,965 and US-A-3 255 506 described.

The roller pair 39 is followed by a further pair of rollers 43 with rollers 44, 46 whose peripheral speeds are lower than those of the rollers 41, 42, so that the filter tow 2 at slightly relaxed in its promotion. The pair of rollers 43 has a smooth rubber roller 44, which is in contact with the steel roller 46. The roller pairs 39 and 43 thus limit the application path 7, which in the present case is arranged approximately horizontally, in which an application device (FIG. 2, reference 47) is arranged in the form of a spraying device.

The applicator 47 sprays the transported filter tow 2 from one or both sides with fine droplets of solvent for the filter tow material, e.g. Triacetin.

The application device 47 may be arranged upstream of the applicator section 7 (not shown here) spreader nozzle, so that the stretched filter tow 2 is further spread and the solvent wets a larger surface of the filter tow 2. The upstream of the roller pair 21 of the Vorreckstrecke 4 spreader nozzles 16, 17 and optionally the spreader nozzle in the order path 7 are pressurized with compressed air.

The order path 7 is a shirring 8 downstream, in which the filter tow 2 is conveyed with predominantly vertical component of a motor-driven roller 53 from bottom to top.

The roller 53 is arranged downstream of a feed path 9. In the feed line 9 also known per se so-called. Stopfdüse is present. After passing through the Stopfdüse the filter tow is fed to a filter rod machine 11.

For more details is expressly on US-A-5 590 449 directed.

In Fig. 2, an applicator 47 for applying a plasticizer, e.g. Triacetin, shown on the expanded filter tow 2 in a schematic cross-sectional view during ongoing production. The strip 2 of filter material is transported according to the conveying direction F from right to left. In the lower area of the applicator 47 are a plurality of application nozzles 31, of which only one is shown, which generates a spray cone 32 with plasticizer droplets of triacetin during ongoing production. By means of the application nozzles 31, a fine mist-like atomization of a plasticizer, e.g. Triacetin, achieved.

The strip 2 is guided through lower stripping plates 33, 34 by the applicator 47. The lower stripping plates 33, 34 are arranged in the lower region of the application device 47 or of the lower housing part 13. Above the filter tow 2, three stripping plates 15 are arranged in the closed housing of the application device 47 on the upper housing part 12.

The upper Abstreifbleche 15 are hook-shaped or V-shaped or formed in the manner of a parabola. On the underside of the stripping plates 15, the spread-out filter tow strip 2 is transported past according to the marked conveying direction F. In this case, touching the filter tow 2 and the stripping plate 15 in the lowest point of the stripping plate 15.

In addition, a further stripper plate 14 is disposed above the filter tow 2 in the entry region of the strip 2 in the applicator 47.

By the application of triacetin on the filter tow 2, for example by means of application nozzles or a job brush, the not shown here, droplets of triacetin are applied to the filter tow 2. Due to the volatility of the triacetin droplets, the atmosphere in the applicator housing 47 is enriched with triacetin droplets.

In the embodiments shown in Figs. 3 to 7, when the production was stopped, the supply of triacetin via the application nozzles 31 was stopped and a production stop was initiated at the filter material processing machine.

In Fig. 3, an inventive arrangement is shown on the applicator 47 according to a first embodiment in cross section. In this case, the job on the application nozzle 31 is completed and the strip 2 stopped. After a complete machine stop, the closed housing of the applicator 47 is opened, wherein the upper housing part 12 is raised after completion of Triacetinauftrags and the promotion of the strip 2 upwards. The lower housing part 13 remains stationary.

After opening the housing of the applicator 47 rod-shaped support rods 18, 20 are moved from below to the strip 2 upwards, so that the strip 2 is deflected from its original position during the production of filter strands or filter rods upwards. In this case, the strip 2 is no longer on the contact-carrying lower Abstreifblechen 33, 34 of the lower housing part 13, so that after deflection of the strip 2 by the raised support rods 18, 20 of the strip 2 is held in the range of Auftragsstrecke above the housing part 13 at a distance. Here, the strip 2 has no contact with facilities or organs or the like of the order line 7, where triacetin deposits are present.

The lifting of the support rods 18, 20 is indicated in the drawing by vertically upwardly pointing arrows.

The production position of the strip 2 is shown in dashed lines in Fig. 3. By raising the dormant, i. resting strip 2 by means of the vertically moving support rods 18, 20, the strip 2 is in the position shown in Fig. 3 in a rest position in which triacetin with the filter tow 2 is not in contact.

In order to form a relaxation of the stretched strip 2 during the standstill time of the machine or of the filter tow strip, the contacting contact between the rollers 41, 42 of the roller pair 39 can be terminated by pivoting the roller 42 away in a development. This is indicated in Fig. 3 with a left-pointing arrow on the roller 42.

In the context of the invention, it is also possible that the input-side roller pair of the stretching section (see Fig. 1, reference numeral 24) is opened, so that the input-side rollers (see Fig. 1, reference numerals 26, 27) no longer in touching contact stand. Due to the fact that during a machine standstill the preparation of the strip 2 is also terminated by stretching, the strip 2 is in a relaxed state in the region of the application path 7 when the production is at a standstill.

Furthermore, it is conceivable that, when the machine or production stop is at a standstill, the contacting contact between the rollers 44, 46 of the output-side roller pair at the application path 7 is likewise terminated for the duration of the standstill.

To start production on a processing machine, the support rods 18, 20 are lowered. Subsequently, the upper housing part 12 is moved downward, whereby the housing of the applicator 47 is closed. Subsequently or simultaneously, the pairs of rollers of the application line and the stretching device are brought into touching contact, provided that during the downtime the corresponding rolls of the roll pairs have been separated from each other.

For commissioning, the strip 2, which is conveyed horizontally in the application line 7, is sprayed after its stretching in the stretching section (see Fig. 1, reference numeral 6) in the order path with triacetin over the application nozzle 31 (see Fig. 2). ,

4, an embodiment of an arrangement for carrying out a method according to the invention is shown in cross section. After initiation of the production stop, the upper housing part 12 of the applicator 47 is raised. With the initiation of the machine stop, the delivery of triacetin from the application nozzles 31 is stopped. At the same time or after the promotion of the strip 2 is also terminated.

The filter tow 2 is during the downtime of the machine in predetermined, especially uniform, time intervals for a certain period of time by back and forth turning the rollers 41, 42 of the input side roller pair 39 and by, preferably synchronous or synchronized, back and forth turning of the rollers 46th , 44 of the output-side roller pair 43 on the order path 7 moves back and forth.

By the forward and backward movement of the strip 2 at the contact points of the Abstreifbleche 33, 34 is deposited on the Abstreifblechen 33, 34 triacetin uniformly on the underside of the strip 2 and taken up by the filter tow 2. As a result, an adhesion to the resolution of the filter tow strip is avoided even with longer service lives of the machine.

In Fig. 5 is a plan view of the Auftragsstrecke 7 is shown, with only the lower housing part 13 is located for reasons of better representability. In the context of the invention, it is possible that the rollers 41, 42 and 43, 44 are moved back and forth individually or together in the longitudinal axial direction, i. transverse to the usual production conveying direction of the strip 2, so that the filter tow 2 is moved back and forth transversely to the conveying direction, whereby also a uniform distribution of the filter material deposits the Abstreifbleche 33, 34 takes place on the filter tow 2.

In the context of the invention, it is possible for the movement possibilities of the filter tow strip 2 shown in FIGS. 4 and 5 to be combined with one another in the conveying direction or against the conveying direction during the production of the strip and at the same time transversely to the conveying direction of the material strip 2. Moreover, it is also within the scope of the invention also possible that when the stationary material strip 2, the lower housing part 13 is moved relative to the fixed or held strip 2.

6 shows a further exemplary embodiment of an arrangement for carrying out a method according to the invention, in which the filter material strip 2 on the input side and the output side of the application device 47 via schematically drawn air nozzles 28, in contrast to the exemplary embodiment in FIG. 3 in this exemplary embodiment (FIG. 30 is kept in motion such that the filter tow 2 provided with the Triacetinablagerungen Abstreifbleche 33, 34 during the standstill of the machine or the treatment process keeps moving. As a result, contact between the non-promoted material strip 2 and the triacetin konterminierten lower housing part is avoided.

The air nozzles 28, 30 are arranged on the input side and output side of the applicator 47 and generate an air flow or a kind of air cushion, so that the strip 2 is held in the air in the area of the applicator 47.

By the application of compressed air to the filter material strip via the nozzles 28, 30 arranged laterally or below, the strip 2 is held between the lower housing part 13 and the upper housing part.

In the embodiment shown in FIG. 7, when a production stop is initiated, the supply of triacetin via the application nozzles 31 is terminated. When shutting down the preparation device, the stretching of the strip of material 2 in the stretching section (see Fig. 1, reference numeral 6) is terminated at the same time by the touching rollers of the pairs of rollers (see Fig. 1, reference numerals 24, 39) spaced apart or removed become.

In the phase-out phase, i. During or during the shutdown of the machine, the non-stretched or untreated strip 2 is conveyed by the treatment device 47, so that the strip of filter material 2 absorbs deposits of triacetin in the housing chamber and removes the strip from the chamber or the application line 7 while conveying the strip ,

As a result, the excess triacetin is taken up in the applicator 47 and on the conveying organs and from the triacetinhaltigen Area of the order 7 conveyed out. A production stop can be initiated, for example, when the machine center, for example, receives a signal from a filter magazine that the filter memory is filled and the production should be interrupted or must. Only when falling below a predetermined volume of the filter memory, the production of filter rods is resumed.

Within the scope of the invention, it is obvious to a person skilled in the art that certain features of different embodiments can be combined with one another in the context of the disclosure of the present patent application in order to prevent the filter material strip 2 from sticking in the area of the applicator 47 during a production stop, such an embodiment being thereon is directed that an automatic restart of the production process should be possible with little or no manual intervention.

The essential essence of the invention is that after the interruption of the Triacetinauftrags on a strip of filter material, the strip is moved so that the strip is not in contact with Triacetinablagerungen or the strip is moved in the downtime temporarily, so that recorded in the downtime Triacetinmengen not lead to a resolution of the strip and disturbances are avoided when starting the production process.
