Abstract

A carder for manufacturing non-woven materials from fibrous material which includes at least one draw-in roller, and a licker-in roller following the draw-in roller and rotating in the same direction. There are at least two worker rollers of the same diameter following the licker-in roller, the two worker rollers rotating in the same direction and at a greater speed than the licker-in roller. At least one doffing cylinder cooperates with the last of the worker rollers. Further worker rollers follow the two worker rollers, with the various worker rollers being separated by transfer regions between adjacent rollers. The relative speeds and the spacings between adjacent rollers are adjustable to control the proportion of fibrous material that can be returned to previous worker rollers or sent to succeeding worker rollers. An air-guiding box projects into at least one of the transfer regions, the box being adjustable in height and width.

Description

Die Erfindung betrifft eine Krempel zur Vliesherstellung aus Fasermaterial mit den Merkmalen des ersten Teils des Anspruchs 1.The invention relates to a card for nonwoven manufacture from fiber material with the features of the first part of claim 1.

Bei einer solchen, aus der DE-C-33 15 839 vorbekannten Krempel greift ein keilförmiger Luftleitkasten in den Übergabebereich zwischen Hauptwalze und Wirrwalze bzw. Wirrwalze und Hauptwalze ein, der in der Höhe und quer zum Walzenmantel verstellbar angeordnet ist.In such a card, known from DE-C-33 15 839, a wedge-shaped air guide box engages in the transfer area between the main roller and the tangling roller or the tangling roller and the main roller, which is adjustable in height and transversely to the roller shell.

Diese vorbekannte Krempel ist bezüglich der Arbeitsgeschwindigkeit nicht voll befriedigend.This previously known card is not fully satisfactory in terms of working speed.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs genannte Krempel bezüglich der erreichbaren Arbeitsgeschwindigkeit zu verbessern.The invention has for its object to improve the aforementioned card with respect to the achievable working speed.

Erfindungsgemäß wird diese Aufgabe durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst. Die Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung an.According to the invention, this object is achieved by the features specified in the characterizing part of claim 1. The subclaims indicate advantageous embodiments of the invention.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachstehenden Beschreibung, in der Ausführungsbeispiele anhand der Zeichnungen im einzelnen erläutert sind. Dabei zeigt:

Further features and advantages of the invention result from the following description, in which exemplary embodiments are explained in detail with reference to the drawings. It shows:
Fig. 1
An embodiment of a card according to the invention in a schematic section perpendicular to the axis of rotation of the machine rollers or drums:
Fig. 2
another embodiment in Fig. 1 corresponding representation.

Wie Fig. 1 erkennen läßt, weist die erfindungsgemäße Krempel bei dem dort gezeigten Ausführungsbeispiel eine Einzugswalze 10 auf, die ggf., wie auch bei der gattungsgemäßen Krempel, mit einer Einzugsmulde oder dergleichen zusammenwirken kann; natürlich können auch mehrere Einzugswalzen bzw. -mulden vorgesehen sein. Die Einzugswalze 10, die beispielsweise mit einer Umdrehungsgeschwindigkeit von 10 m/min. laufen kann, beaufschlagt eine gleichsinnig hiermit laufende Vorwalze 12, deren Umdrehungsgeschwindigkeit beispielsweise bei ca. 300 m/min. liegen kann. Der Vorwalze 12, die also gleichsinnig mit der Einzugswalze 10 läuft und deren Oberfläche wie diejenige der Einzugswalze 10 und auch, bei dem gezeigten Ausführungsbeispiel, bei allen nachgeschalteten Walzen bzw. Trommeln, mit einer entsprechend gestalteten Sagezahngarnitur versehen ist, ist eine gegensinnig laufende erste Arbeitstrommel 14 nachgeordnet, die ihrerseits wiederum mit einer zweiten Arbeitstrommel 16 sowie einer dritten Arbeitstrommel 18 zusammenwirkt. Die zweite Arbeitstrommel 16 und die dritte Arbeitstrommel 18 beaufschlagen eine vierte Arbeitstrommel 20, der wiederum eine fünfte Arbeitstrommel 22 sowie eine sechste Arbeitstrommel 24 nachgeschaltet sind, wobei der fünften Arbeitstrommel 22 und der sechsten Arbeitstrommel 24 wiederum gemeinsam eine siebte Arbeitstrommel 25 nachgeordnet ist. Die Arbeitstrommeln 14, 16, 18, 20, 22, 24 und 25 haben jeweils eine Umdrehungsgeschwindigkeit von beispielsweise ca. 1400 m/min., wobei die Relativgeschwindigkeiten der Arbeitstrommeln jedoch ebenso wie ihre relativen Abstände, d.h. die Breite der jeweilgen Walzenspalte, einstellbar sind. Den Arbeitstrommeln 14, 16, 18, 20, 22, 24, 25 sind in der aus der Zeichnung ersichtlichen Weise zwei Abnehmerwalzen 26, 27 nachgeschaltet, die gegensinnig zu sämtlichen gleichsinnig laufenden Arbeitstrommeln mit einer Umfangsgeschwindigkeit von beispielsweise ca. 116 m/min. laufen.As can be seen in FIG. 1, the card according to the invention has, in the exemplary embodiment shown there, a feed roller 10 which, as in the generic card, can interact with a feed trough or the like; Of course, several feed rollers or troughs can also be provided. The feed roller 10, for example, at a speed of 10 m / min. can run, impinges a roughing roller 12 running in the same direction, the rotational speed of which, for example, at approximately 300 m / min. can lie. The roughing roller 12, that is runs in the same direction with the feed roller 10 and the surface of which is like that of the feed roller 10 and also, in the exemplary embodiment shown, with all downstream rollers or drums, is provided with an appropriately designed saw tooth set, a counter-rotating first work drum 14 is arranged downstream, which in turn is in turn cooperates with a second working drum 16 and a third working drum 18. The second working drum 16 and the third working drum 18 act on a fourth working drum 20, which in turn is followed by a fifth working drum 22 and a sixth working drum 24, the fifth working drum 22 and the sixth working drum 24 being in turn followed by a seventh working drum 25. The working drums 14, 16, 18, 20, 22, 24 and 25 each have a rotational speed of, for example, approx. 1400 m / min. However, the relative speeds of the working drums as well as their relative spacings, ie the width of the respective roll gaps, can be set . The work drums 14, 16, 18, 20, 22, 24, 25 are followed in the manner shown in the drawing by two take-off rollers 26, 27 which run in the opposite direction to all work drums running in the same direction at a peripheral speed of, for example, approximately 116 m / min. to run.

Die Zeichnung läßt ferner Übertragungsbereiche 28, in denen eine Übertragung des Fasermaterials erfolgt, sowie Speicherbereiche 30 für das Fasermaterial auf den einzelnen Arbeitstrommeln erkennen. Schließlich zeigt die Zeichnung an die entsprechende Form der jeweiligen Arbeitstrommeln angepaßte Luftleitkästen 32, die jeweils keilförmig in die betreffenden Übergabebereiche zwischen miteinander zusammenwirkenden Arbeitstrommeln eingreifen.The drawing also shows transmission areas 28 in which the fiber material is transferred, as well as storage areas 30 for the fiber material on the individual working drums. Finally, the drawing shows air guide boxes 32 which are adapted to the corresponding shape of the respective working drums and which are each wedge-shaped in the respective transfer areas intervene between interacting working drums.

Die insoweit unter Bezugnahme auf Fig. 1 beschriebene Krempel arbeitet in folgender Weise:
Die Einzugswalze 10 fördert in bekannter Weise Fasermaterial in gleichmäßiger Zuführung auf die Vorwalze 12. Von der Vorwalze 12 nimmt die mit erheblichem Verzug, wie dargestellt, gegensinnig hierzu laufende erste Arbeitstrommel 14 das Fasermaterial ab und kardiert es in einem ersten Schritt im Zusammenhang mit der zweiten Arbeitstrommel 16 und der dritten Arbeitstrommel 18. Dabei wird nicht das gesamte von der ersten Arbeitstrommel 14 von der Vorwalze 12 übernommene Fasermaterial sogleich auf die zweite Arbeitstrommel 16 bzw. die dritte Arbeitstrommel 18 übertragen, vielmehr lediglich der in dem Übertragungsbereich 28, wie aus der Zeichnung ersichtlich, vorhandene Teil, während der in dem Speicherbereich 30 vorhandene Anteil des Fasermaterials nochmals ein- oder mehrmals rückgeführt und einer weiteren Kardierung unterworfen wird. Dieselben Verhältnisse herrschen auch zwischen den den Arbeitstrommeln 16, 18 nachgeschalteten weiteren Arbeitstrommeln 20, 22, 24, 25, wobei die Menge der Anteile des jeweils übertragenen und des jeweils rückgespeicherten Fasermaterials durch entsprechende Steuerung der Relativabstände der jeweiligen Arbeitstrommeln bzw. der Relativgeschwindigkeiten derselben einstellbar ist. Die Abnehmerwalze 26 schließlich, an deren Stelle natürlich auch in bekannter Weise ein Mehrfach-Walzenabzug oder dergleichen vorgesehen sein könnte, ggf. auch mit einem Stauchwalzenabzug verbunden, läuft erheblich langsamer als die Arbeitstrommeln, so daß hierauf ein verhältnismäßig stark "zusammengeschobenes" Vlies aufgeschoben wird.The card described so far with reference to FIG. 1 works in the following way:
The feed roller 10 conveys fiber material in a known manner to the pre-roller 12 in a uniform manner. From the pre-roller 12, the first working drum 14, which runs in opposite directions to this with considerable delay, as shown, removes the fiber material and cards it in a first step in connection with the second Work drum 16 and the third work drum 18. Not all of the fiber material taken over by the first work drum 14 from the pre-roller 12 is immediately transferred to the second work drum 16 or the third work drum 18, rather only that in the transmission area 28, as shown in the drawing can be seen, existing part, while the portion of the fiber material present in the storage area 30 is returned one or more times and subjected to a further carding. The same conditions also prevail between the further working drums 20, 22, 24, 25 connected downstream of the working drums 16, 18, the amount of the shares of the respectively transferred and the respectively restored fiber material being adjustable by correspondingly controlling the relative distances of the respective working drums or the relative speeds thereof . Finally, the take-off roller 26, in the place of which a multiple roller take-off or the like could of course also be provided in a known manner, may also be connected to an upsetting roller take-off, runs considerably slower than the working drums, so that a relatively strongly "pushed together" fleece is pushed onto it.

Dadurch, daß die Luftleitkästen 32 vorgesehen sind, die drucklos sein können, vorzugsweise aber in der aus der DE-PS 33 15 839 an sich bekannten Weise mit Druckluft beaufschlagbar sind, lassen sich die in den Übergabebereichen zwischen den jeweils miteinander zusammenwirkenden Arbeitstrommeln insbesondere wegen der hohen Drehzahl der Arbeitstrommeln auftretenden starken Turbulenzen beeinflussen, und zwar bei "druckloser" Ausbildung des betreffenden Luftleitkastens dadurch, daß der Luftleitkasten einen Widerstand für die Luftbewegung bildet, bei positiver Druckluftbeaufschlagung der Luftleitkästen zusätzlich auch durch die hierdurch hervorgerufene Strömungsbeeinflußung. Die Intensität des Luftstromes bzw. insgesamt die erzielte Beeinflußung der Turbulenz in dem jeweiligen Übergabebereich beeinflußt die Gleichmäßigkeit und insgesamt die Wirrvliesstruktur des dort befindlichen Fasermaterials unmittelbar. Der Luftleitkasten 32 bzw. die verschiedenen in den jeweiligen Übergabebereichen vorgesehenen Luftleitkästen 32 ermöglichen es jedoch nicht nur, die Turbulenzen in den jeweiligen Übergabebereichen zu beeinflussen, sondern es läßt sich in diesem Bereichen auch dem bereits vorkardierten Fasermaterial weiter aus Fasermaterial beigeben, auch z.B. Puder, Granulate oder dergleichen, wie dies insgesamt in der DE-C-33 15 839 beschrieben ist, auf die zur Erläuterung und Ergänzung des Erfindungsgedankens insoweit ausdrücklich Bezug genommen wird.The fact that the air guide boxes 32 are provided, which can be depressurized, but can preferably be acted upon with compressed air in the manner known from DE-PS 33 15 839, can be in the transfer areas between the interacting working drums in particular because of the High rotational speed of the working drums influence strong turbulence, namely with "pressure-less" design of the air guide box in question, in that the air guide box forms a resistance to the air movement, with a positive compressed air supply to the air guide boxes in addition also by the flow influence caused thereby. The intensity of the air flow or, overall, the influence of the turbulence achieved in the respective transfer area has a direct influence on the uniformity and on the whole the tangled nonwoven structure of the fiber material located there. The air guide box 32 or the various air guide boxes 32 provided in the respective transfer areas not only make it possible to influence the turbulence in the respective transfer areas, but it is also possible in this area to add the fiber material already pre-carded, including powder, for example. Granules or the like, as described overall in DE-C-33 15 839, to which reference is expressly made to explain and supplement the inventive concept.

Das mittels der erfindungsgemäßen Krempel gemäß Ausführungsbeispiel Fig. 1 erhaltene Vliesmaterial ist über die gesamte Arbeitsweise der Maschine gleichmäßig und hat ein Verhältnis von Längs- zur Querfestigkeit von ca. 1 : 1, wie dies erwünscht ist. Die Arbeitstrommeln gleichen Durchmessers sind auch bei sehr großen Arbeitsbreiten der Maschine durchbiegungsfrei herstellbar. Neben der Behebung des Problems der Walzendurchbiegung gewährleistet der Verzicht auf Arbeiter- und Wenderwalzen einen erheblichen einfacheren konstruktiven Aufbau.The nonwoven material obtained by means of the card according to the invention according to exemplary embodiment FIG. 1 is uniform over the entire operation of the machine and has a ratio of longitudinal to transverse strength of approximately 1: 1, as is desired. The working drums of the same diameter can be produced without bending even with very large working widths of the machine. In addition to eliminating the problem of roll deflection, the absence of worker and turner rolls ensures a considerably simpler construction.

Bei dem in Fig. 2 gezeigten Ausführungsbeispiel wirken mit der Vorwalze 12 zwei Arbeitstrommeln 14, 16 zusammen, denen in der aus der Zeichnung ersichtlichen Weise weitere Arbeitstrommeln 18, 20, 22, 24 und 25 nachgeschaltet sind, die insgesamt einander so zugeordnet sind, daß das mittels der Einzugswalze 10 herangeführte Fasermaterial durch die einzelnen Arbeitstrommeln in gewünschtem Maße weiterübertragen bzw. rückgespeichert wird, wobei natürlich die Vorwalze 12 an der Rückspeicherung nicht beteiligt ist. Die Umdrehungsgeschwindigkeiten der Einzugswalzen 10, der gleichsinnig hiermit laufenden Vorwalze 12 sowie der gegensinnig hierzu laufenden Arbeitstrommeln 12, 14, 16, 20, 22, 24 und 25 sowie auch der Abnehmerwalzen 26, 27 stimmen mit dem in Verbindung mit Fig. 1 angegebenen Werten ggf. überein. Im übrigen arbeitet die Vorrichtung in der weiter oben in Bezugnahme auf das Ausführungsbeispiel Fig. 1 erläuterten Weise.In the embodiment shown in FIG. 2, two working drums 14, 16 cooperate with the roughing roller 12, which are followed by further working drums 18, 20, 22, 24 and 25 in the manner shown in the drawing, which are assigned to one another in such a way that the fiber material brought in by means of the feed roller 10 is further transferred or stored back to the desired extent by the individual working drums, the front roller 12 of course not being involved in the storage. The speeds of rotation of the feed rollers 10, of the preliminary roller 12 running in the same direction as well as of the working drums 12, 14, 16, 20, 22, 24 and 25 running in the opposite direction as well as of the take-off rollers 26, 27 are correct with the values given in connection with FIG match. Otherwise, the device operates in the manner explained above with reference to the exemplary embodiment in FIG. 1.
