- the filter towers 4 and 6 are deflected to overlying deformation rollers 62 and 63, which in the illustrated embodiment at its periphery have a V-shaped cross-section, in particular the Figures 3 and 6 reveal.
- the deflection rollers 62 and 63 form a coaxially juxtaposed arrangement, which is mounted on one side on the rear wall 32 of the machine frame 20. How the particular FIGS. 6 and 7 can be seen, the hitherto flat spread filter tow strips 4 and 6 are formed by the forming rollers 62 and 63 to round tow strands 64 and 66.
- the center distance of both tow guideways 2 and 3 is determined by the width of the spread filter tow strips 4 and 6 and is slightly larger than the sum of the widths of the filter tow strips 4 and 6. Usually the center distance of both tow guideways 2 and 3 is at least about 330 mm. For further processing in a double-strand machine, however, it is necessary to reduce the center distance between the round tow strands 64 and 66 to the deformation rollers 62 and 63 to the strand center distance of a double-strand machine, which is usually 38mm.
- pairs of guide pulleys can be provided which, after the deformation rollers 62, 63, can guide the now round tow ropes 64, 66 in any desired direction.
- a distraction of the towstring 64, 66 can be made in the direction strand.
- pulleys can be used to redirect the round towstring 64, 66 in different directions, for example, to serve physically separate from each other set up single-strand machines.
- By such a deflection can also twist the tow in the stretching zone or twist.
- it is conceivable, with regard to the possibility of such a deflection to set up the previously described conditioning machine at an angle with respect to a downstream filter strand unit or a cigarette rod machine.
- it is also conceivable by such a deflection to arrange the filter towballs 8, 9 at a different location relative to the machine frame 20.
- the center distance between the two round Towstrnature 64, 66 to reduce consists in the arrangement of two cranked inlet fingers 68 and 69, as provided in the illustrated embodiment, and in particular in the FIGS. 6 and 7 are shown recognizable.
- the two round tow strands 64, 66 run slightly angled from the deformation rollers 62, 63 in the direction of the inlet fingers 68, 69. Since the guide rollers 62, 63 provide an obliquely running Towstrang 64, 66, the inlet fingers 68, 69 have a cranked Shape, so that there exiting tow strands 64, 66 are aligned again parallel to each other under the required reduced center distance.
- the inlet fingers 68, 69 are hollow and have a tapering in the direction of the tow line 64, 66 shape. Furthermore, these figures show that the inlet fingers 68, 69 are double cranked, resulting in a particularly gentle deflection of the towstring 64, 66 can achieve.
- the inlet fingers 68, 69 from their in the FIGS. 6 and 7 be shown pivoting out of the operating position shown.
- the inlet fingers 68, 69 attached to a carrier 70, as in FIG. 8 is shown.
- This carrier 70 is pivotally suspended via two mutually parallel pivot arms 72, 74 on a support member 76, which in turn on the machine frame 20 and preferably on the rear wall 32 (see. FIG. 1 ) is mounted.
- the two pivot arms 72, 74 form a parallelogram in that the pivot axis of the first pivot arm 72 connecting the first hinge 70 has the same distance to the pivot axis of the second pivot arm 74 with the holder 70 connecting the second joint as the pivot axis of the first Swivel arm 72 with the support member 76 connecting the third hinge 79 to the pivot axis of the second pivot arm 74 with the support member 76 connecting the fourth joint 80.
- the pivot axes extend at right angles to the direction of the towstring 64, 66.
- the common support 70 for the two inlet fingers 68, 69 suspended from a pivotable in the direction Towstrnature parallelogram, whereby the two inlet fingers 68, 69 in the direction opposite to the running direction of the towstring 64, 66 and thus in the upstream direction gemä ß arrow A from FIG. 8 from her to the FIGS. 6 to 8 shown operating position can be pivoted out.
- This filter strand unit Downstream of the machine described above is a filter strand unit, which is not shown in the figures.
- This filter strand unit has inter alia a wrapping device for wrapping the tow strands 64, 66 with wrapping paper and an adhesive application device for gluing the coated paper.
- adhesive either slow setting adhesive, in particular cold glue, or fast setting adhesive, in particular hot melt adhesive. Because of the different properties of these types of adhesives, it makes sense to form the adhesive applicator so that both types of adhesive can be applied.
- the advantage of such a measure is in particular that the fast-setting adhesive initially causes an immediate fixation of the wrapping paper, while the slow-setting adhesive leads to a permanent bond.
- a fast-setting adhesive such as hot melt adhesive has the disadvantageous property that the adhesive effect is lost after a long time. Therefore, especially at high processing speeds, the double application of slow and fast setting adhesives is recommended. In contrast, it is sufficient at low processing speeds, so in particular in partial load operation, which is possible in particular in the double-strand machine described above, only slowly setting adhesive.
- two independent picking devices are provided for transferring the manufactured products to two filter deliveries for two different cigarette production mashines. Due to the arrangement of such separate removal devices, which are not shown in the figures, it is possible to use different and especially physically separately set up Filterstranghowen or cigarette manufacturing machines.
- such removal means may comprise a push-in drum or a transfer spreader.

Für die Herstellung von unterschiedlichen Filtersorten kann es zweckmäßig sein, dass die Filtertowbereitstellungsmittel für jede Towführungsbahn ein unterschiedliches Filtertowmaterial bereitstellen. Üblicherweise bestehen die Filtertowbereitschaftsmittel aus zwei oder mehreren Ballen, wobei von jedem Ballen ein Filtertowstreifen abgezogen wird, oder aus einem Ballen und einer nachgeschalteten Schneideeinrichtung, die den vom Ballen abgezogenen Materialstreifen in Längsrichtung in zwei oder mehrere getrennte Filtertowstreifen aufschneidet.For the production of different types of filters, it may be appropriate that the filter tow providing means provide a different filter tow material for each tow path. Typically, the filter tow standby means consist of two or more bales, with each bale stripping off a filter tow, or a bale and a downstream cutter which cuts the strip of material withdrawn from the bale longitudinally into two or more separate filter tows.
Jede Bearbeitungseinrichtung weist Mittel zum Ausbreiten, Recken und/oder Behandeln des Filtertowmaterials auf. Erfindungsgemäß sind diese Mittel zum Ausbreiten, Recken und/oder Behandeln des Filtertowmaterials allesamt in Bezug auf jede Towführungsbahn jeweils separat steuerbar, um die zuvorbeschriebenen Effekte zu erzielen. So ist in jeder Towführungsbahn jeweils ein separat steuerbares Mittel zum Recken vorgesehen, um den betreffenden Filtertowstreifen in der zugehörigen Towführungsbahn individuell zu recken. Die Mittel zum Recken des Filtertowmaterials eignen sich besonders gut für die individuelle Beeinflussung der Filtertowstreifen in den jeweiligen Towführungsbahnen, weil sie charakteristische Eigenschaften, wie z.B. die Dichte oder den Zugwiderstand, der hergestellten Produkte unmittelbar beeinflussen.Each processing device has means for spreading, stretching and / or treating the filter tow material. According to the invention, these means for spreading, stretching and / or treating the filter tow material are each separately controllable with respect to each tow path, in order to achieve the effects described above. Thus, in each Towführungsbahn each have a separately controllable means for stretching provided to individually stretch the respective filter tow in the associated Towführungsbahn. The means for stretching the filter tow material are particularly well suited for the individual manipulation of the filter tow strips in the respective tow guideways because they have characteristic properties, such as e.g. the density or draw resistance directly affecting manufactured products.
Jeder Towführungsbahn sind Mittel zum Ausbreiten, Recken und/oder Behandeln des Filtertowmaterials zugeordnet und die Mittel zum Ausbreiten, die Mittel zum Recken und/oder die Mittel zum Behandeln bilden jeweils eine Einheit, in der sie quer zur Richtung der Towführungsbahnen nebeneinander angeordnet sind. Bei dieser Ausführung sind demnach entsprechend der Anzahl der Towführungsbahnen eine entsprechende Anzahl von Mitteln zum Ausbreiten, eine entsprechende Anzahl von Mitteln zum Recken und/oder eine entsprechende Anzahl von Mitteln zum Behandeln vorgesehen, wobei sämtliche Mittel zum Ausbreiten eine Einheit, sämtliche Mittel zum Recken eine Einheit und/oder sämtliche Mittel zum Behandeln jeweils eine Einheit bilden.Each Towführungsbahn are associated with means for spreading, stretching and / or treating the Filtertowmaterials and the means for spreading, the means for stretching and / or the means for treating each form a unit in which they are arranged transversely to the direction of the Towführungsbahnen side by side. In this embodiment, according to the number of Towführungsbahnen a corresponding number of means for spreading, a corresponding number of means for stretching and / or a corresponding number of means are provided for treatment, all means for spreading a unit, all means for stretching a Unit and / or all means for treating each form a unit.
Erfindungsgemäß weist jedes Mittel zum Ausbreiten und/oder Recken ein von zugehörigen Antriebsmitteln angetriebenes, einseitig gelagertes Walzenpaar auf. Die einseitige Lagerung der Walzenpaare hat den Vorteil einer besseren Zugänglichkeit, insbesondere beim Einrichten der Vorrichtung oder im Falle der Beseitigung von Fehlfunktionen.According to the invention, each means for spreading and / or stretching has a roller pair driven by associated drive means and mounted on one side. The one-sided storage of the roller pairs has the advantage of better accessibility, especially when setting up the device or in the case of elimination of malfunctions.
Die Walzenpaare der eine Einheit bildenden Mittel sind zum Ausbreiten und/oder Recken koaxial nebeneinanderliegend gelagert, wodurch sich eine besonders platzsparende Anordnung ergibt. Dabei kann die erste Walze des äußeren Walzenpaares auf einer ersten Welle und die erste Walze des inneren Walzenpaares auf einem ersten Rohr sitzen, durch das sich die erste Welle hindurch erstreckt. Die gleiche getrennte Lagerung mit Hilfe einer Welle-Hohlwelle-Anordnung lässt sich auch für die zweiten Walzen der Walzenpaare realisieren. Demnach sind bei dieser Ausführung zumindest die Walzen des inneren Walzenpaares als Hohlwalzen ausgebildet.The pairs of rollers of the unit forming means are coaxially juxtaposed for spreading and / or stretching, resulting in a particularly space-saving arrangement. In this case, the first roller of the outer roller pair can sit on a first shaft and the first roller of the inner roller pair on a first tube, through which the first shaft extends. The same separate storage by means of a shaft-hollow shaft arrangement can also be realized for the second rolls of the roller pairs. Accordingly, in this embodiment, at least the Rolls of the inner roller pair formed as a hollow rollers.
Eine weitere bevorzugte Ausführung zeichnet sich dadurch aus, dass das Mittel zum Behandeln des Filtertowmaterials eine sich winklig, sich vorzugsweise quer, über die Towführungsbahnen erstreckende Sprühkastenanordnung aufweist, die auf ihrer den Towführungsbahnen zugewandten Wand mit den Towführungsbahnen zugeordneten Abgabeöffnung zur Abgabe von Behandlungsflüssigkeit auf das Filtertowmaterial versehen ist, wobei an den Stellen zwischen den Towführungsbahnen jeweils eine erste Trennwand innerhalb der Sprühkastenanordnung und jeweils eine zweite Trennwand auf der den Towführungsbahnen zugewandten Wand angeordnet ist, um gegenseitige Beeinflussungen bei der Behandlung des Filtertowmaterials in den verschiedenen Towführungsbahnen und insbesondere Fehlbenetzungen durch Verwirbelungen zu vermeiden.A further preferred embodiment is characterized in that the means for treating the Filtertowmaterials an angularly, preferably transversely, over the Towführungsbahnen extending spray box arrangement, on its the Towführungsbahnen facing wall with the Towführungsbahnen associated discharge opening for delivery of treatment liquid on the Filtertowmaterial is provided, wherein at the points between the tow guideways in each case a first partition wall within the Sprühkastenanordnung and a second partition on the Towführungsbahnen facing wall is arranged to prevent mutual interference in the treatment of the filter tow material in the various tow guideways and in particular misting by turbulence ,
Bei einer Weiterbildung der zuvor genannten Ausführung ist der Querschnitt der Abgabeöffnungen in Bezug auf jede Towführungsbahn, vorzugsweise mit Hilfe von beweglichen Dosierblechen, separat veränderbar, um das Filtertowmaterial in jeder Towführungsbahn individuell behandeln zu können. Dabei können vorzugsweise pro Towführungsbahn entweder eine Abgabeöffnung, die gewöhnlich schlitzförmig ausgebildet ist, oder eine Vielzahl von Abgabeöffnungen, die gewöhnlich als runde Bohrungen ausgebildet sind, vorgesehen sein.In a further development of the aforementioned embodiment, the cross-section of the discharge openings with respect to each Towführungsbahn, preferably with the aid of movable metering plates, separately changed to treat the filter tow material in each Towführungsbahn individually. In this case, preferably either a dispensing opening, which is usually slot-shaped, or a plurality of dispensing openings, which are usually designed as round bores, may be provided per tow path.
Zweckmäßigerweise ist die Sprühkastenanordnung unter Druck setzbar. Alternativ oder zusätzlich ist es aber auch denkbar, dass die Sprühkastenanordnung mindestens eine von einem Antrieb angetriebene rotierende Bürste enthält, die die Behandlungsflüssigkeit durch die Abgabeöffnungen schleudert.Conveniently, the spray box assembly is pressurizable. Alternatively or additionally, however, it is also conceivable that the spray box arrangement contains at least one rotary brush driven by a drive, which hurls the treatment liquid through the discharge openings.
Ferner können stromabwärts nach einer Formungseinrichtung zum Formen von zwei runden Filtertowsträngen aus zwei Filtertowstreifen zwei doppelt gekröpfte, konische Einlauffinger vorgesehen sein, durch die jeweils ein Filtertowstrang geführt wird, um den Abstand zwischen den Filtertowsträngen zu reduzieren und eine parallele Ausrichtung der Filtertowstränge zu erzielen.Furthermore, downstream of a shaping device for forming two round filter tows from two filter tows, two double-cranked conical inlet fingers may be provided through which a filter tow strand is fed to reduce the distance between the filter tows and achieve parallel alignment of the filter tows.
Bei einer Weiterbildung der zuvor erwähnten Ausführung können die Einlauffinger an einer gemeinsamen Halterung befestigt sein, die an einem im Wesentlichen in Richtung der Filtertowstränge verschwenkbaren Parallelogrammgerüst aufgehängt ist. Auf diese Weise lassen sich beide Einlauffinger, vorzugsweise parallel zu einer Maschinenwand, nach hinten verschwenken, und zwar insbesondere zum Zwecke des Einrichtens der Maschine oder zum Zwecke der Wartung.In a further development of the aforementioned embodiment, the inlet fingers can be fastened to a common holder, which is suspended from a parallelogram frame which can be pivoted substantially in the direction of the filter tow cord. In this way, both inlet fingers, preferably parallel to a machine wall, pivot backwards, in particular for the purpose of setting up the machine or for the purpose of maintenance.
Ferner können stromabwärts nach der Formungseinrichtung Umlenkmittel, die vorzugsweise mindestens eine Umlenkrolle aufweisen, zur Umlenkung der runden Filtertowstränge vorgesehen sein, um den Towlauf in jede beliebige Richtung zu verschwenken. Derartige Umlenkmittel können beispielsweise ähnlich wie die zuvor erwähnten Einlauffinger zur Reduzierung des Abstandes zwischen den Filtertowsträngen verwendet werden. Alternativ oder zusätzlich lässt sich durch die Anordnung von Umlenkmitteln eine Eckaufstellung zwischen der Vorrichtung zum Aufbereiten von Filtertowmaterial und einer sich daran anschlie-ßenden Filterstrangeinheit realisieren. Schließlich könnte durch ein Verwinden des Tows in der Reckzone die Aufstellung von Towballen wahlweise an verschiedenen Stellen möglich sein.Furthermore, downstream of the shaping device, deflection means, which preferably have at least one deflection roller, can be provided for deflecting the round filter towstring so as to pivot the towpath in any direction. Such deflection means can be used, for example, similar to the aforementioned inlet fingers for reducing the distance between the filter tows. Alternatively or additionally, can be realized by the arrangement of deflection a Eckaufstellung between the apparatus for processing of filter tow material and a subsequent thereto ßenden Filterstrangeinheit. Finally, by twisting the tow in the stretching zone, the deployment of towballs could optionally be possible at different locations.
Am Ende jeder Towführungsbahn ist ferner eine separate Entnahmeeinrichtung vorgesehen, die vorzugsweise eine Einstoßtrommel oder eine Übergabespinne aufweist, um die geschnittenen Filtertowstäbe von einer Bewegung in ihrer Längsrichtung in eine Bewegung quer zu ihrer Längsrichtung zu überführen. Durch die Anordnung solcher separaten Entnahmeeinrichtungen ist es möglich, verschiedene und insbesondere körperlich getrennt aufgestellte Filterstrangeinheiten oder Zigarettenherstellungsmaschinen zu bedienen. Die
Schließlich betrifft die Erfindung eine Vorrichtung zur Herstellung von Filtern für stabförmige Rauchartikel, mit einer Vorrichtung der zuvor erörterten Art sowie einer Umhüllungseinrichtung zur Umhüllung der Filtertowstreifen mit Umhüllungsmaterial und einer Klebeauftragseinrichtung zum Verkleben des Umhüllungsmaterials. Dabei kann die Klebeauftragseinrichtung erste Mittel zum Auftragen von langsam abbindendem Klebstoff, insbesondere Kaltleim, und zweite Mittel zum Auftragen von schnell abbindendem Klebstoff, insbesondere Heißschmelzklebstoff, aufweisen. Eine solche Ausbildung der Klebmittelauftragseinrichtung bildet einen eigenständigen Erfindungsaspekt und lässt sich auch bei Einstrang-Anlagen realisieren. Der Vorteil einer solchen Klebeauftragseinrichtung besteht insbesondere darin, dass gleichzeitig sowohl der langsam abbindende Klebstoff als auch der schnell abbindende Klebstoff appliziert werden können, wobei der schnell abbindende Klebstoff zunächst eine sofortige Fixierung des Umhüllungsmaterials bewirkt, während der langsam abbindende Klebstoff zu einer dauerhaften Verklebung führt. Denn ein schnell abbindender Klebstoff wie beispielsweise Heißschmelzklebstoff besitzt die nachteilige Eigenschaft, dass die Klebewirkung nach längerer Zeit verloren geht. Deshalb bietet sich gerade bei hohen Verarbeitungsgeschwindigkeiten die doppelte Applikation von langsam und schnell abbindenden Klebstoffen an Demgegenüber ist es bei niedrigen Verarbeitungsgeschwindigkeiten, also insbesondere im Teillastbetrieb, ausreichend, nur die ersten Mittel zum Auftragen von langsam abbindendem Klebstoff zu aktivieren.Finally, the invention relates to a device for the production of filters for rod-shaped smoking articles, comprising a device of the type discussed above and a wrapping device for wrapping the filter tow strips with wrapping material and an adhesive application device for bonding the wrapping material. The adhesive application device may comprise first means for applying slow-setting adhesive, in particular cold glue, and second means for applying fast-setting adhesive, in particular hot-melt adhesive. Such a design of the adhesive applicator forms an independent aspect of the invention and can also be implemented in single-line systems. The advantage of such an adhesive applicator is, in particular, that both the slow-setting adhesive and the fast-setting adhesive can be applied simultaneously, wherein the fast-setting adhesive initially causes an immediate fixation of the wrapping material, while the slow-setting adhesive leads to a permanent bond. Because a fast-setting adhesive such as hot melt adhesive has the disadvantageous property that the adhesive effect is lost after a long time. Therefore, especially at high processing speeds, the double application of slow and fast setting adhesives On the other hand, it is sufficient at low processing speeds, ie in part-load operation, to activate only the first means for applying slow-setting adhesive.

In den Figuren ist zum Teil vollständig und zum Teil in Einzelheiten eine Maschine gemäß der Erfindung zum Aufbereiten von Filtertowmaterial für die Herstellung von Filtern für stabförmige Rauchartikel wie insbesondere Zigaretten im Strangverfahren dargestellt, wobei die Figuren jeweils nur im Wesentlichen die für das Verständnis der Erfindung erforderlichen Teile enthalten. Im Maschinenbau übliche Bestandteile der Maschine wie beispielsweise Einzelheiten des Maschinengestells, Halterungen, Lagerungen und Verkleidungen sind in der Zeichnung im Interesse ihrer besseren Überschaubarkeit im Wesentlichen nicht darstellt. Gleiche Teile sind in allen Figuren mit denselben Bezugszeichen versehen.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings, there is shown partly and completely in detail a machine according to the invention for processing filter tow material for the manufacture of rod smoking filters such as in particular cigarettes in the string process, the figures being only substantially those required for the understanding of the invention Parts included. In machine engineering usual components of the machine such as details of the machine frame, brackets, bearings and panels are in the drawing in the interest of their clarity not essentially represents. Identical parts are provided with the same reference numerals in all figures.
Die dargestellte Filtertowaufbereitungsmaschine weist zwei Towführungsbahnen 2 und 3 auf, welche nebeneinander zwei Filtertowstreifen 4 und 6 durch die Maschine führen. Die Filtertowstreifen 4 und 6 werden von einem Filtertowvorrat 7 abgezogen, der im dargestellten Ausführungsbeispiel zwei Filtertowballen 8 und 9 nebeneinander enthält. Alternativ ist es aber auch denkbar, die Filtertowstreifen 4 und 6 in einem gemeinsamen Ballen zu bevorraten oder einen breiteren Materialstreifen aus einem einzigen Ballen abzuziehen und anschlie-βend in Richtung seiner Längserstreckung durch eine Schneideeinrichtung in zwei getrennte Filtertowstreifen aufzuschneiden.The illustrated filter fabric preparation machine has two
Oberhalb des Filtertowvorrates 7 weist die Maschine im dargestellten Ausführungsbeispiel ein Umlenk- und Towausbreitungsorgan 10 auf, das am oberen Ende eines Stützarmes 12 angeordnet ist und zwei nebeneinander liegende gleiche Towführungen 14 aufweist. Ferner sind am Umlenk- undAbove the filter tow reservoir 7, the machine in the illustrated embodiment, a deflection and
Towausbreitungsorgan 10 erste Ausbreiterdüsen 16 vorgesehen, die jeweils auf beide Filtertowstreifen 4 und 6 wirken, um diese jeweils in einen flächigen Streifen auszubreiten.
An einem schematisch dargestellten Maschinengestell 20 sind zweite Ausbreiterdüsen 22 angeordnet, an denen die vom Umlenk- und Towausbreitungsorgan 10 kommenden Filtertowstreifen 4 und 6 entlang geführt werden.On a schematically illustrated
An die zweiten Ausbreiterdüsen 22 schließt sich eine zweibahnige Streckeinrichtung 24 an. Wie insbesondere die
Die ersten und zweiten Bremswalzenpaare 26 und 27, die ersten und zweiten Streckwalzenpaare 28 und 29 sowie die dritten und vierten Streckwalzenpaare 30 und 31 sind jeweils koaxial zueinander und nebeneinander liegend angeordnet. In diesem Zusammenhang ist ferner insbesondere auf die einseitige Lagerung der Streckwalzenpaare 28, 29 und 30, 31 an einer vertikalen Rückwand 32 des Maschinengestells 20 hinzuweisen, was eine gute Zugänglichkeit insbesondere beim Einrichten einer Maschine oder im Falle der Beseitigung von Fehlfunktionen ermöglicht, wie insbesondere die
Die einseitige Lagerung insbesondere der Streckwalzen ist im dargestellten Ausführungsbeispiel mit Hilfe einer Welle-Hohlwelle-Anordnung realisiert, was beispielhaft anhand der ersten Walzen 28a, 29a der ersten und zweiten Streckwalzenpaare 28, 29 in
Demnach ist jedem der ersten, zweiten, dritten und vierten Streckwalzenpaare 28, 29, 30 und 31 ein eigener Antrieb zugeordnet, der von einer nicht dargestellten Regelungseinrichtung separat steuerbar ist. Auf diese Weise können die Eigenschaften der beiden Filtertow-streifen 4 und 6 in den beiden Towführungsbahnen 2 und 3 unabhängig voneinander geregelt und somit eingestellt werden, wodurch es möglich ist, Filterstäbe in den beiden Towführungsbahnen 2 und 3 mit unterschiedlichen Eigenschaften herzustellen.Accordingly, each of the first, second, third and fourth pairs of draw rolls 28, 29, 30 and 31 is assigned its own drive, which can be controlled separately by a control device, not shown. In this way, the properties of the two filter tow strips 4 and 6 in the two Towführungsbahnen 2 and 3 can be controlled independently and thus adjusted, making it possible to produce filter rods in the two Towführungsbahnen 2 and 3 with different properties.
Wie die
Die dritten und vierten Streckwalzenpaare 30 und 31 werden durch die diesen zugeordneten separaten Antriebe mit höherer Umfangsgeschwindigkeit angetrieben als die ersten und zweiten Streckwalzenpaare 28 und 29, so dass zwischen den ersten und dritten Streckwalzenpaaren 28 und 30 sowie zwischen den zweiten und vierten Streckwalzenpaaren 29 und 31 jeweils eine definierte Reckung des zugehörigen Filtertowstreifens 4 bzw. 6 stattfindet. Wie bereits erwähnt und in
Dies gilt auch, wie bereits erwähnt, für die Bremswalzenpaare 26 und 27. Denn das erste Bremswalzenpaar 26 ist dem ersten Filtertowstreifen 4 und das zweite Bremswalzenpaar 27 dem zweiten Filtertowstreifen 6 zugeordnet. Die Bremswalzenpaare 26 und 27 werden deshalb auch getrennt durch jeweils separat zugeordnete Betätigungsorgane betätigt, mit denen die von den Bremswalzenpaaren 26, 27 auf die Filtertowstreifen 4, 6 ausgeübte Bremskraft beeinflußt werden kann. Als Betätigungsorgane, die in den Figuren nicht dargestellt sind, können beispielsweise elektrische Bremsen vorgesehen sein, die auf die Bremswalzen 26, 27 ein Bremsmoment übertragen, oder es können elektrische, hydraulische oder pneumatische Verstellorgane vorgesehen sein, welche mindestens eine Walze der beiden Bremswalzenpaare 26, 27 quer zu deren Drehachse verstellen und somit den Anpressdruck der Bremswalzen gegeneinander beeinflussen.This also applies, as already mentioned, for the brake roller pairs 26 and 27. For the first pair of
Stromabwärts von der Anordnung der dritten und vierten Streckwalzenpaare 30, 31 folgt als Mittel zum Behandeln des Filtertowmaterials mit Zusatzstoffen eine Auftragseinrichtung 44 zum Aufbringen von flüssigem Weichmacher auf die ausgebreiteten Filtertowstreifen 4, 6. Wie insbesondere die
In dem Sprühkasten 46 kann in bekannter Weise mindestens eine zylindrische rotierende Bürste angeordnet sein, die im Einzelnen nicht dargestellt ist und von einem ebenfalls nicht dargestellten Motor angetrieben wird. Die Weichmacherzufuhr erfolgt durch eine oder mehrere ebenfalls nicht dargestellte Öffnungen an der Seite oder der Unterseite des Sprühkastens 46, durch die der Weichmacher mittels ebenfalls nicht dargestellter Pumpen aus einem ebenfalls nicht dargestellten Weichmachervorrat zugeführt wird.In the
Im dargestellten Ausführungsbeispiel wird die Abgabemenge des Weichmachers insbesondere durch Einstellung der Öffnungsweite der Öffnungen 49 und 50 geregelt. Hierzu sind sogenannte Dosierbleche 53 und 54 vorgesehen, die in Bewegungsrichtung der Filtertowstreifen 4, 6 bewegbar sind und wahlweise die Öffnungen 49, 50 teilweise oder vollständig öffnen oder verschließen. Die Dosierbleche 53 und 54 werden durch nicht dargestellte Betätigungsorgane angetrieben, welche durch eine ebenfalls nicht dargestellte Regelungseinrichtung unabhängig voneinander angesteuert werden. Somit wird die Öffnungsweite der Öffnungen 49, 50 unabhängig voneinander geregelt. Dies bietet neben der individuellen Steuerung der Bremswalzenpaare 26, 27 und der Streckwalzenpaare 28 bis 31 eine weitere Möglichkeit, die Eigenschaften der beiden Filtertowstreifen 4 und 6 individuell zu beeinflussen und zu bestimmen, um aus den Filtertowstreifen 4 und 6 unterschiedliche Produkte herstellen zu können.In the illustrated embodiment, the discharge amount of the plasticizer is controlled in particular by adjusting the opening width of the
Durch die Bewegung der gereckten und sich nun entspannenden Filtertowstreifen 4 und 6 über die Auftragseinrichtung 44 hinweg kann es zu Verwirblungen des abgegebenen Weichmachers kommen, welche die Verteilung des versprühten Weichmachers unerwünscht beeinflusst und zu Fehlbenetzungen führt. Um solche Fehlbenetzungen zu vermeiden, sind die beiden Öffnungen 49 und 50 durch ein Trennblech voneinander getrennt, wie insbesondere die
Aufgrund einer solchen unabhängigen Regelung der Weichmacherzufuhr und - abgabe ist es beispielsweise denkbar, bei einem Filtertowstreifen eine Trockenentnahme vorzunehmen, indem die Weichmachzufuhr und- abgabe vollständig abgestellt wird, während der andere Filtertowstreifen normal weiter behandelt wird.On the basis of such an independent regulation of the plasticizer supply and discharge, it is conceivable, for example, to carry out a dry removal in a filter tow strip by completely switching off the softener supply and dispensing, while the other filter tow strip is treated further normally.
Wie insbesondere die
Durch die Transportwalzenpaare 60 und 61 werden die Filtertowstreifen 4 und 6 zu darüber liegenden Verformungsrollen 62 und 63 umgelenkt, die im dargestellten Ausführungsbeispiel an ihrem Umfang einen V-förmigen Querschnitt haben, wie insbesondere die
Der Mittenabstand beider Towführungsbahnen 2 und 3 wird durch die Breite der ausgebreiteten Filtertowstreifen 4 und 6 bestimmt und ist ein wenig größer als die Summe der Breiten der Filtertowstreifen 4 und 6. Gewöhnlich liegt der Mittenabstand beider Towführungsbahnen 2 und 3 bei mindestens etwa 330 mm. Für eine weitere Verarbeitung in einer Doppelstrangmaschine ist es jedoch erforderlich, den Mittenabstand zwischen den runden Towsträngen 64 und 66 nach den Verformungsrollen 62 und 63 auf den Strangmittenabstand einer Doppelstrangmaschine zu reduzieren, der gewöhnlich 38mm beträgt.The center distance of both tow
Hierzu können in den Figuren nicht dargestellte Umlenkrollenpaare vorgesehen sein, welche nach den Verformungsrollen 62, 63 die jetzt runden Towstränge 64, 66 in jede beliebige Richtung lenken können. So kann eine Ablenkung der Towstränge 64, 66 in Richtung Strang vorgenommen werden. Derartige Umlenkrollen können aber dazu verwendet werden, die runden Towstränge 64, 66 in unterschiedliche Richtungen umzulenken, um beispielsweise körperlich voneinander getrennt aufgestellte Einstrangmaschinen zu bedienen. Durch eine solche Umlenkung lässt sich ferner das Tow in der Reckzone verwinden oder twisten. Weiterhin ist es denkbar, im Hinblick auf die Möglichkeit einer solchen Umlenkung die zuvor beschriebene Aufbereitungsmaschine in einem Winkel gegenüber einer nachgeschalteten Filterstrangeinheit oder einer Zigarettenstrangmaschine aufzustellen. Schließlich ist es durch eine solche Umlenkung ferner denkbar, die Filtertowballen 8, 9 an einer anderen Stelle gegenüber dem Maschinengestell 20 anzuordnen.For this purpose, pairs of guide pulleys, not shown in the figures, can be provided which, after the
Eine andere Möglichkeit, den Mittenabstand zwischen den beiden runden Towsträngen 64, 66 zu reduzieren, besteht in der Anordnung zweier gekröpfter Einlauffinger 68 und 69, wie sie im dargestellten Ausführungsbeispiel vorgesehen und insbesondere in den
Zwecks besserer Bedienbarkeit und Wartung sollten die Einlauffinger 68, 69 aus ihrer in den
Der zuvor beschriebenen Maschine nachgeschaltet ist eine Filterstrangeinheit, die in den Figuren nicht dargestellt ist. Diese Filterstrangeinheit weist unter anderem eine Umhüllungseinrichtung zur Umhüllung der Towstränge 64, 66 mit Umhüllungspapier sowie eine Klebeauftragseinrichtung zum Verkleben des umhüllten Papieres auf. Es ist bekannt, als Klebstoff entweder langsam abbindenden Klebstoff, insbesondere Kaltleim, oder schnell abbindenden Klebstoff, insbesondere Heißschmelzklebstoff, zu verwenden. Wegen der unterschiedlichen Eigenschaften dieser Klebstoffarten bietet es sich an, die Klebauftragseinrichtung so auszubilden, dass beide Klebstoffarten appliziert werden können. Der Vorteil einer solchen Maßnahme besteht insbesondere darin, dass der schnell abbindende Klebstoff zunächst eine sofortige Fixierung des Umhüllungspapiers bewirkt, während der langsam abbindende Klebstoff zu einer dauerhaften Verklebung führt. Denn ein schnell abbindender Klebstoff wie beispielsweise Heißschmelzklebstoff besitzt die nachteilige Eigenschaft, dass die Klebewirkung nach längerer Zeit verloren geht. Deshalb bietet sich gerade bei hohen Verarbeitungsgeschwindigkeiten die doppelte Applikation von langsam und schnell abbindenden Klebstoffen an. Demgegenüber ist es bei niedrigen Verarbeitungsgeschwindigkeiten, also insbesondere im Teillastbetrieb, der insbesondere bei der zuvor beschriebenen Doppelstrangmaschine möglich ist, ausreichend, nur langsam abbindenden Klebstoff aufzutragen.Downstream of the machine described above is a filter strand unit, which is not shown in the figures. This filter strand unit has inter alia a wrapping device for wrapping the
Schließlich sind noch zwei unabhängige Entnahmeeinrichtungen zur Weitergabe der hergestellten Produkte an zwei Filterabgaben für zwei unterschiedliche Zigarettenproduktionsmashinen vorgesehen. Durch die Anordnung solcher separaten Entnahmeeinrichtungen, die in den Figuren nicht dargestellt sind, ist es möglich, verschiedene und insbesondere körperlich getrennt aufgestellte Filterstrangeinheiten oder Zigarettenherstellungsmaschinen zu bedienen. Vorzugsweise können solche Entnahmeeinrichtungen eine Einstoßtrommel oder eine Übergabespinne aufweisen.Finally, two independent picking devices are provided for transferring the manufactured products to two filter deliveries for two different cigarette production mashines. Due to the arrangement of such separate removal devices, which are not shown in the figures, it is possible to use different and especially physically separately set up Filterstrangeinheiten or cigarette manufacturing machines. Preferably, such removal means may comprise a push-in drum or a transfer spreader.
