Abstract

For fastening working elements (7), such as carding elements, in relation to a rotating fibre-opening roller (1), such as a licker-in roller, it is proposed that the working elements be fastened on the bearing bushes (4) of the roller by means of an attachment (6) which at least partially surrounds the bearing bush.

Description

Die Erfindung betrifft eine Vorrichtung zur Befestigung von Arbeitselementen, insbesondere eines Festkardierelementes, bezüglich einer drehenden, faserauflösenden Walze.The invention relates to a device for fastening working elements, in particular a fixed carding element, with respect to a rotating, fiber-dissolving roller.

Es ist bei Spinnereivorbereitungsmaschinen, insbesondere bei Karden, bekannt, dass die Arbeitselemente wie Ausscheidemesser, Festkardierelement oder dergleichen direkt auf dem Maschinengestell befestigt werden und mit Einstellmitteln wie exzentrisch gelagerten Scheiben, Schlitzen, Unterlagsscheiben oder dergleichen bezüglich einer drehenden Walze auf den richtigen Abstand eingestellt werden. Diese Einstellungen sind sehr aufwendig und müssen regelmässig in mehreren Teilschritten durchgeführt werden, da eine Verstellung des Einstellmittels und ein nachheriges Fixieren durch eine Schraube wieder eine leichte Verschiebung der vorzunehmenden Einstellung, das heisst Abstand, mit sich bringt. Für solche Einstellungen ist es notwendig, mit Blattlehren und ähnlichen Arbeitsmitteln die Abstände in einem immer enger werdenden Toleranzbereich genau einzuhalten.It is known in spinning preparation machines, in particular in carding machines, that the working elements such as the cutting knife, fixed carding element or the like are fastened directly to the machine frame and are adjusted to the correct distance with respect to a rotating roller using adjusting means such as eccentrically mounted disks, slots, washers or the like. These settings are very complex and have to be carried out regularly in several steps, since an adjustment of the setting means and subsequent fixing with a screw again results in a slight shift in the setting to be made, that is to say the distance. For such settings, it is necessary to use sheet gauges and similar tools to keep the distances within an increasingly narrow tolerance range.

Die Erfindung stellt sich nun die Aufgabe, ebenso genaue Abstände innerhalb eines engen Toleranzbereiches einfacher zu erreichen als nach den vorhergehend beschriebenen Methoden.The object of the invention is now to achieve equally precise distances within a narrow tolerance range more easily than according to the methods described above.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of patent claim 1.

Bislang ist man immer davon ausgegangen, dass die faserauflösenden Walzen direkt in einem Maschinengestell gelagert sind und die dazu gehörenden Arbeitselemente wie Ausscheidemesser und fest angeordnete Kardierelemente ebenfalls auf dem Maschinengestell befestigt sein sollten. Wegen der Fertigungstoleranzen ist es daher notwendig, die vorgeschriebenen Arbeitsabstände mittels Einstellmittel wie Unterlagsscheiben, Schlitze, Schrauben usw. erst bei der Montage einzustellen. Da nun die Herstellung von faserauflösenden Walzen wie Stiftwalzen, mit Sägezähnen versehenen Garniturwalzen oder Nadelwalzen mit immer grösserer Präzision vorgenommen werden kann, ist der äussere Umfang nahezu ideal zylindrisch und sind die Toleranzen im Durchmesser minimal. Diese Erkenntnis hat der Erfinder dazu veranlasst, nach neuen Mitteln zu suchen, um die Arbeitselemente präziser bezüglich der Walze anordnen zu können. Eine passgenaue Befestigung des Arbeitselementes auf der Lagerbuchse der drehenden Walze hat neben dem Vorteil, dass nunmehr weniger Bauteile benötigt sind, auch den unter anderem enormen Vorteil, dass mit wesentlich weniger Arbeitsaufwand - d.h. mit viel weniger Einstellarbeiten - eine Textilmaschine gefertigt werden kann.So far, it has always been assumed that the fiber-dissolving rollers are mounted directly in a machine frame and that the associated working elements such as knives and fixed carding elements should also be attached to the machine frame. Because of the manufacturing tolerances, it is therefore necessary to set the prescribed working distances using setting means such as washers, slots, screws, etc. only during assembly. Since the production of fiber-dissolving rollers such as pin rollers, saw rollers with set teeth or needle rollers can now be carried out with ever greater precision, the outer circumference is almost ideally cylindrical and the tolerances in diameter are minimal. This finding prompted the inventor to search for new means in order to be able to arrange the working elements more precisely with respect to the roller. A precisely fitting fastening of the working element on the bearing bush of the rotating roller has the advantage, in addition to the fact that fewer components are now required, and the enormous advantage, among other things, that with significantly less work - i.e. with much less adjustment work - a textile machine can be manufactured.

Weitere Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung, in welcher die Erfindung anhand eines in den Zeichnungen dargestellten Beispieles näher erläutert wird.Further advantages of the invention result from the following description, in which the invention is explained in more detail with reference to an example shown in the drawings.

Es zeigt:

  • Fig.1 eine schematische Teilansicht einerfaserauflösenden Walze mit einem Querschnitt durch ein Festkardierelement, und
  • Fig. 2 einen Schnitt in Richtung A- in Figur 1 durch die Lagerbuchse und das Arbeitselement.
It shows:
  • 1 shows a schematic partial view of a fiber-dissolving roller with a cross section through a fixed carding element, and
  • Fig. 2 shows a section in the direction A- in Figure 1 through the bearing bush and the working element.

In Figur 1 ist eine faserauflösende Walze 1 - hier Briseurwalze - gezeigt, wobei die Nadeln, Stifte oder Sägezahngarnitur hier nicht sichtbar ist. Die Walze 1 ist mit ihren Wellen 2 in Lagerbuchsen 4 gelagert. Der rechte Teil I der Welle 2 ist geschnitten dargestellt, da sie weiter mit einem nicht dargestellten Antrieb verbunden ist. Die Achse der Walze 1 ist mit 3 bezeichnet. Rein schematisch ist in der Buchse 4 ein Wälzlager 5 dargestellt, dass ein Rollenlager oder ein Nadellager sein kann. Auf den Buchsen 4 ist jeweils einen Aufsatz 6 sichtbar auf denen ein Arbeitselement 7, hier ein Festkardierelement, befestigt ist. Das Festkardierelement 7 besteht aus einem Träger und einem oder mehreren Kämmeinsätzen 9. Der Träger 8 ist mit nichtdargestellten Schrauben auf dem Aufsatz 6 angeschraubt.FIG. 1 shows a fiber-dissolving roller 1 - here a beater roller - with the needles, pins or sawtooth set not being visible here. The roller 1 is mounted with its shafts 2 in bearing bushes 4. The right part I of the shaft 2 is shown in section, since it is further connected to a drive, not shown. The axis of the roller 1 is designated 3. A roller bearing 5 that can be a roller bearing or a needle bearing is shown purely schematically in the bushing 4. On the sockets 4, an attachment 6 is visible on which a working element 7, here a fixed carding element, is attached. The fixed carding element 7 consists of a carrier and one or more combing inserts 9. The carrier 8 is screwed onto the attachment 6 with screws, not shown.

In Figur 2 sind dieselben Elemente wie in Figur 1 mit denselben Bezugszeichen dargestellt. Wie aus dieser Figur ersichtlich, ist der Aufsatz 6 im Bereich des Kardierelementes 7 prismatisch ausgebildet, das heisst die Verbindungsflächen mit dem Träger 8 sind übereinstimmend mit den Flächen eines n-eckigen Prismas. Der Träger 8 ist aus einem gezogenen Aluminiumprofil und besitzt Hohlräume 10, damit die Stabilität gewährleistet ist und gleichzeitig die in Betrieb entstehende Wärme genügend abgeleitet werden kann. Auf der linken Seite des Trägers 8 ist ein Ausscheidemesser 11 angeordnet, dass mit zwei Inbusschrauben 12 auf dem Träger 8 befestigt ist. Nicht sichtbar sind Schlitze in dem Ausscheidemesser 11, womit die genaue Position der Messerspitze bezüglich der Sägezahngarnitur der Walze 1 eingestellt werden kann. Der Träger 8 ist wie in Figur 2 ersichtlich, zumindest im Bereich des Aufsatzes 6 ebenfalls prismatisch ausgebildet, wodurch eine genaue Positionierung des Trägers 8 bezüglich des Aufsatzes 6 automatisch erfolgt. Wie ersichtlich aus Figur 2 ist der Aufsatz 6 einstückig mit der Lagerbuchse 4, die üblicherweise aus Gusseisen ausgebildet ist. Es kann jedoch auch sein, dass der Aufsatz 6 ein separates Teil ist, dass auf der Lagerbuchse 4 aufgeschraubt ist. Diese Lösung hat aber den Nachteil, dass dadurch ein weniger genauer Abstand der Arbeitselemente bezüglich der Walze möglich ist, da die Schraubverbindung weitere Toleranzen mit sich bringt. Die ohne Einstellung erforderliche Genauigkeit kann bei der gezeigten Ausführung dadurch erreicht werden, weil die Auflage der Kämmeinsätze oder Kämmelemente 9 genau in derselben oder in einer genau dazu parallelen Ebene liegt wie die Auflage des Trägers 8 auf den Lagerbuchsen 4. Für eine solche Genauigkeit ist es nicht unbedingt notwendig, dass die Flächen des Aufsatzes 6 mindestens teilweise prismatisch ausgebildetsind, sondern es könnten auch Ausnehmungen in dem Träger 8 vorgesehen sein. Diese Ausnehmungen können beispielsweise eckige Hohlkehle sein, wozu auf dem Aufsatz 6 kongruente Elemente vorgesehen sind. Jedoch wird die prismatische Ausbildung wegen der Einfachheit der Lösung bevorzugt. Der Aufsatz 6 könnte jedoch auch auf dem Träger 8 und dementsprechende Einschliffe auf der Lagerbuchse 4 vorgesehen sein, um die vorgenannte Bedingung zu erfüllen.In Figure 2, the same elements as in Figure 1 are shown with the same reference numerals. As can be seen from this figure, the attachment 6 is prismatic in the region of the carding element 7, that is to say the connecting surfaces with the carrier 8 are in line with the surfaces of an n-square prism. The carrier 8 is made of a drawn aluminum profile and has cavities 10 so that the stability is ensured and at the same time the heat generated during operation can be dissipated sufficiently. On the left side of the carrier 8 there is a knockout knife 11 which is fastened to the carrier 8 with two Allen screws 12. Slits are not visible in the discharge knife 11, with which the exact position of the knife tip with respect to the saw tooth set of the roller 1 can be adjusted. As can be seen in FIG. 2, the carrier 8 is likewise prismatic, at least in the region of the attachment 6, as a result of which the carrier 8 is automatically positioned precisely with respect to the attachment 6. As can be seen from Figure 2, the attachment 6 is in one piece with the bearing bush 4, which is usually formed from cast iron. However, it can also be the case that the attachment 6 is a separate part that is screwed onto the bearing bush 4. However, this solution has the disadvantage that a less precise spacing of the working elements with respect to the roller is possible because the screw connection brings with it further tolerances. The accuracy required without adjustment can be achieved in the embodiment shown because the support of the combing inserts or combing elements 9 lies exactly in the same or in a plane parallel to it as the support of the carrier 8 on the bearing bushes 4. It is such an accuracy it is not absolutely necessary for the surfaces of the attachment 6 to be at least partially prismatic, but it could also be Recesses can be provided in the carrier 8. These recesses can be, for example, angular grooves, for which purpose congruent elements are provided on the attachment 6. However, prismatic design is preferred because of the simplicity of the solution. The attachment 6 could, however, also be provided on the carrier 8 and corresponding cuts on the bearing bush 4 in order to meet the aforementioned condition.
