Description

Die vorliegende Erfindung betrifft ein Kardiersegment mit Schmutzabscheider, welches Kardiersegment mindestens einen stabförmigen Halter zur Aufnahme der den Kratzenbeschlag bildenden Sägezahnstreifen aufweist, wobei mindestens ein Halter lösbar und einstellbar in einem Rahmen angeordnet ist.The present invention relates to a carding segment with dirt separator, which carding segment has at least one rod-shaped holder for receiving the sawtooth strips forming the scraper fitting, at least one holder being detachably and adjustably arranged in a frame.

Schmutzabscheider werden in Karden dazu verwendet, Schmutzteile, Schalen, Schalennissen etc. von den Baumwollfasern abzustreifen, um die Verunreinigungen vor dem nachfolgenden Spinnereiprozess auszuscheiden. Ein solcher Schmutzabscheider ist z.B. in der FR-A-2 242 492 offenbart. Das Abstreifen erfolgt mechanisch, wobei dem Abstreiforgan eine Absaugvorrichtung nachgeschaltet ist, mittels welcher die abgeschiedenen Teilchen entfernt werden. Zum Abstreifen werden Messer aus verschleissfestem, gehärtetem Stahl eingesetzt, wobei der Abstand der jeweiligen Messerschneide von den Spitzen der Tambourgarnituren äusserst klein ist, beispielsweise 0,05 bis 0,1 mm. Dies bedingt ein genaues Einstellen der Lage der Abstreifmesser. Weiter beträgt der Winkel, welcher zwischen einer vom Messer bestimmten Ebene und einer Tangentenebene gebildet ist, die durch die Schnittlinie zwischen der erstgenannten Ebene und der Hüllfläche des Tambours verläuft, etwa 45°. Je kleiner der Winkel ist, desto grösser ist die Schmutzausscheidung, jedoch wächst auch der Grad der Faserausscheidung an. Je grösser der Winkel ist, desto kleiner ist die Schmutzausscheidung. Somit ist es erforderlich, dass auch dieser Winkel genau eingestellt werden kann. Bei bekannten Karden wird der Schmutzabscheider durch eine separate Einrichtung gebildet, benötigt entsprechend Platz entlang dem Tambour und entsprechend aufwendige Einstellarbeiten beim Zusammenbau, der Wartung oder dem Austauschen abgenützter Teile.Dirt separators are used in cards to wipe off dirt particles, shells, shell nits etc. from the cotton fibers in order to separate the impurities before the subsequent spinning process. Such a dirt separator is disclosed, for example, in FR-A-2 242 492. The stripping is carried out mechanically, with the stripping member being followed by a suction device by means of which the separated particles are removed. Knives made of wear-resistant, hardened steel are used for stripping, the distance of the respective knife edge from the tips of the drum sets being extremely small, for example 0.05 to 0.1 mm. This requires an exact adjustment of the position of the doctor blades. Furthermore, the angle which is formed between a plane determined by the knife and a tangent plane which runs through the intersection line between the first-mentioned plane and the envelope surface of the drum is approximately 45 °. The smaller the angle, the greater the dirt excretion, but the degree of fiber excretion also increases. The larger the angle, the more the dirt excretion is smaller. It is therefore necessary that this angle can also be set precisely. In the case of known cards, the dirt separator is formed by a separate device, requires corresponding space along the spool and correspondingly expensive adjustment work when assembling, maintaining or replacing worn parts.

Es ist Aufgabe der vorliegenden Erfindung, die oben genannten Nachteile zu beheben und eine gedrängte, wartungsfreundliche Ausführung eines Schmutzabscheiders zu zeigen, bei der überdies die erwähnten Einstellarbeiten sehr einfach durchgeführt werden können.It is an object of the present invention to remedy the disadvantages mentioned above and to show a compact, maintenance-friendly design of a dirt separator, in which, moreover, the adjustment work mentioned can be carried out very easily.

Erfindungsgemäss wird nun ein Kardiersegment mit einem Schmutzabscheider vorgeschlagen, bei dem der Rahmen einen Messertragabschnitt aufweist, auf dem ein Messer zur Schmutzabscheidung lageverstellbar angeordnet ist, das sich in einen mit dem Rahmen verbundenen Schmutzabsaugeraum hineinerstreckt und dessen Schneide beim tambourseitigen Ende angeordnet ist.According to the invention, a carding segment with a dirt separator is now proposed, in which the frame has a knife support section on which a knife for dirt separation is arranged in a positionally adjustable manner, which extends into a dirt suction space connected to the frame and whose cutting edge is arranged at the end on the drum side.

Mit dieser Konstruktion wird der Vorteil erzielt, dass eine starre und gedrängte Bauform vorliegt. Ein Auswechseln einzelner Verschleissteile sowie die Montage oder Demontage der Gesamtheit der Teile ist äusserst einfach und kostengünstig. Auch können die einzelnen Arbeitselemente, wie Messer und Kratzenbeschläge, nachgestellt oder neu eingestellt werden, ohne dass eine Neueinstellung jeweils anderer mit demselben Rahmen verbundener Arbeitselemente notwendig ist.The advantage of this design is that it is rigid and compact. Replacing individual wearing parts and assembling or disassembling all of the parts is extremely simple and inexpensive. The individual work elements, such as knives and scraper fittings, can also be readjusted or readjusted without the need to readjust other work elements connected to the same frame.

Gemäss einer bevorzugten Ausführung weist der Messertragsabschnitt eine Anzahl Messerauflageflächen enthaltende Vorsprünge und eine Anzahl Gewindelöcher auf, wobei die Winkelstellung des Messers relativ zu einem Jeweiligen Tambour durch auf Messerauflageflächen aufgelegte Unterlagsplatten wählbar ist, wobei das Messer Langlöcher aufweist und diese Langlöcher durchsetzende, in die Gewindelöcher eingeschraubte Kopfschrauben mit dem Messertragsabschnitt verbunden ist, welche Langlöcher ein Einstellen des Abstandes der Schneide von einem jeweiligen Tambour ermöglichen.According to a preferred embodiment, the knife support section has a number of projections containing knife support surfaces and a number of threaded holes, the angular position of the knife relative to a respective drum being selectable by base plates placed on knife support surfaces, the knife having elongated holes and these Cap screws penetrating elongated holes and screwed into the threaded holes are connected to the knife support section, which elongated holes enable the distance between the cutting edge and a respective drum to be adjusted.

Gemäss einer weiteren Ausführung ist das Messer über Langlöcher enthaltende Schubgelenke am Messertragsabschnitt gelagert und mittels im Messertragsabschnitt eingeschraubter Schraubenbolzen, die durch im Messer ausgebildete, weitere Langlöcher verlaufen, mit dem Messertragsabschnitt verbunden, wobei zum Einstellen der Winkelstellung des Messers relativ zu einem jeweiligen Tambour jeder Schraubenbolzen mit mindestens einer Mutter ausgerüstet ist, und welche Langlöcher der Schubgelenke mit den Langlöchern im Messer derart gleichgerichtet sind, dass ein Einstellen des Abstandes der Schneide von einem jeweiligen Tambour ermöglicht ist.According to a further embodiment, the knife is mounted on the knife support section via sliding joints containing elongated holes and is connected to the knife support section by means of screw bolts screwed into the knife support section and running through further elongated holes formed in the knife, each screw bolt being adjusted relative to a respective spool for adjusting the angular position of the knife is equipped with at least one nut, and which elongated holes of the sliding joints are aligned with the elongated holes in the knife in such a way that it is possible to adjust the distance of the cutting edge from a respective drum.

Bei einem Kardiersegment, bei dem eine Anzahl in Kardierrichtung hintereinander angeordnete Halter vorhanden sind, sind zwischen den Haltern vorhandene Zwischenräume über im Rahmen ausgebildete Durchbohrungen mit dem Schmutzabsaugeraum in Verbindung.In the case of a carding segment in which a number of holders arranged one behind the other in the carding direction are present, intermediate spaces between the holders are connected to the dirt suction space via perforations formed in the frame.

Im folgenden wird die Erfindung anhand von zwei Ausführungen darstellenden Zeichnungen näher erläutert.
Es zeigt:

  • Fig. 1 einen Querschnitt durch eine erste Ausführung eines Kardiersegmentes mit einem Schmutzabscheider, und
  • Fig. 2 einen Querschnitt durch eine weitere Ausführung eines Kardiersegmentes mit einem Schmutzabscheider.
In the following, the invention is explained in more detail with reference to drawings showing two versions.
It shows:
  • Fig. 1 shows a cross section through a first embodiment of a carding segment with a dirt separator, and
  • Fig. 2 shows a cross section through a further embodiment of a carding segment with a dirt separator.

In den beiden Figuren sind Einzelteile, die einander entsprechen, mit denselben Bezugszeichen bezeichnet.In the two figures, individual parts that correspond to one another are identified by the same reference symbols.

In den Figuren bezeichnet die Bezugsziffer 1 jeweils einen stabförmigen Halter, der in bekannter Weise über Clips 20 die den Kratzenbeschlag bildenden Sägezahnstreifen 2 trägt. Ein jeweiliger Halter 1 ist mittels Kopfschrauben 21 lageverstellbar mit einem den Haltern 1 gemeinsamen Rahmen 3 verbunden. Der Rahmen 3 ist oben von einer Kopfplatte 22 abgeschlossen, welche mittels Kopfschrauben 23 auf dem Rahmen 3 aufgeschraubt ist.In the figures, reference numeral 1 denotes a rod-shaped holder, which is known in the art Way over clips 20 carries the sawtooth strips 2 forming the scraper fitting. A respective holder 1 is adjustably connected by means of cap screws 21 to a frame 3 common to the holders 1. The frame 3 is closed at the top by a head plate 22 which is screwed onto the frame 3 by means of cap screws 23.

Der Rahmen 3 ist nun derart ausgebildet, dass er einen Messertragabschnitt 4 aufweist, auf welchem das Messer 5 zum Abstreifen der Verunreinigungen der bearbeiteten Fasern dient. Der jeweilige, sich relativ zu diesem Kardiersegment, beispielsweise einer Wanderdeckelkarde, bewegende Tambour rotiert mit einer Drehzahl von mehreren 100 RPM.The frame 3 is now designed in such a way that it has a knife support section 4, on which the knife 5 serves to scrape off the impurities in the processed fibers. The respective drum moving relative to this carding segment, for example a revolving card, rotates at a speed of several 100 RPM.

Das Messer 5 erstreckt sich in einem Schmutzabsaugeraum 6, der grundsätzlich ein Absaugrohr ist und einem Saugzug zum Wegstransport der abgestreiften Verschmutzungen ausgesetzt ist. Das Messer 5 weist eine Schneide 7 auf, deren Abstand von den Zahnspitzen der auf dem Tambour aufgewickelten Garnitur ca. 0,05 bis 0,1 mm beträgt.The knife 5 extends in a dirt suction space 6, which is basically a suction pipe and is subjected to a suction for transporting away the stripped dirt. The knife 5 has a cutting edge 7, the distance from the tooth tips of the clothing wound on the drum is approximately 0.05 to 0.1 mm.

Es wird nun insbesondere auf die Fig. 1 hingewiesen. Der Rahmen 3 weist beim Messertragabschnitt 4 eine Anzahl Vorsprünge 9 auf. Das Messer 5 ist auf diesen Vorsprüngen aufgelegt. Um nun die Winkelstellung des Messers 5 relativ zur gedachten Tangentenebene einzustellen, welche durch die Schnittlinie zwischen der vom Messer 5 bestimmten Ebene und der Hüllfläche des Tambours 24 verläuft, werden Unterlagsplatten 11 verwendet. Solche werden je nach Bedarf auf einen oder mehrere der Messerauflageflächen 8 der Vorsprünge 9 aufgelegt, so dass der beschriebene Winkel des Messers 5 zum Tambour 24 äusserst einfach und schnell eingestellt werden kann. Das Messer 5 ist über Kopfschrauben 13 mit dem Messertragabschnitt 4 verbunden, wobei dieser Messertragabschnitt 4 entsprechende Gewindelöcher 10 enthält. Das Messer 5 ist mit Langlöchern 12 ausgerüstet, so dass es zum Tambour hin und von diesem weg verschiebbar ist, womit der Abstand der Messerschneide 7 von den Zahnspitzen der Garnitur des Tambours sehr genau und einfach eingestellt werden kann.Reference is now made in particular to FIG. 1. The frame 3 has a number of projections 9 in the knife support section 4. The knife 5 is placed on these projections. In order to adjust the angular position of the knife 5 relative to the imaginary tangent plane, which runs through the intersection between the plane determined by the knife 5 and the envelope surface of the reel 24, underlay plates 11 are used. Depending on requirements, these are placed on one or more of the knife support surfaces 8 of the projections 9, so that the described angle of the knife 5 to the drum 24 can be set extremely simply and quickly. The knife 5 is connected via head screws 13 to the knife support section 4, this knife support section 4 containing corresponding threaded holes 10. The knife 5 is equipped with slots 12, so that it The spool can be moved towards and away from it, so that the distance of the knife edge 7 from the tooth tips of the set of the spool can be set very precisely and easily.

Bei der gezeichneten Ausführung sind vorhandene Zwischenräume 18 zwischen den Haltern 1 über Bohrungen 19, die im Rahmen 3 vorhanden sind und Löchern 25 in der Wand des Schmutzabsaugeraumes 6 mit demselben verbunden, so dass auch feinster, sich in diesen Zwischenräumen 18 ansammelnder Staub, abgesogen werden kann.In the illustrated embodiment, existing gaps 18 between the holders 1 via bores 19 which are present in the frame 3 and holes 25 in the wall of the dirt extraction space 6 are connected to the same, so that even the finest dust accumulating in these gaps 18 is extracted can.

Der Schmutzabsaugeraum 6 ist rohrförmig und liegt mit einem Wandabschnitt dichtend an der Kopfplatte 22 an, welche den Rahmen 3 oben abschliest. Weiter hintergreift der Schmutzabsaugeraum 6 mit einem Wandendabschnitt 31 das Messer 5. Ein weiterer Wandendabschnitt 32 des Schmutzabsaugeraums 6 liegt im montierten Zustand auf einer kurz vor dem Messer 5 endenden Tambourdeckplatte 33 auf. Damit ist der Strömungsweg der mit den Verunreinigungen abgesogenen Luft genau definiert, wobei eine platzsparende Konstruktion erzielt wird.The dirt extraction space 6 is tubular and lies with a wall section sealingly against the head plate 22, which closes off the frame 3 at the top. The dirt suction chamber 6 also engages behind the knife 5 with a wall end section 31. In the assembled state, a further wall end section 32 of the dirt suction chamber 6 rests on a drum cover plate 33 which ends just before the knife 5. The flow path of the air drawn off with the impurities is thus precisely defined, a space-saving construction being achieved.

Es wird nun auf die Fig. 2 hingewiesen, in welcher eine weitere Ausführung dargestellt ist. Das Kardiersegment ist gleich dem der Fig. 1 ausgebildet, mit der Ausnahme, dass der Messertragsbschnitt 4 eine ander Formgebung aufweist. Das Messer 5 weist Schwenkzapfen 26 auf, die in Langlöcher 14 in Vorsprüngen 27 des Rahmens 3 hineinragen, so dass ein Schubgelenk 15 gebildet ist. Das Messer 5 lässt sich also einerseits mit dem Zapfen 26 in den Langlöchern 14 schwenken und andererseits gegen den Tambour hin und von diesem weg bewegen. Weiter ist das Messer 4 von Schraubenbolzen 16 durchsetzt, die jeweils in ein Gewindeloch 28 im Rahmen 3 eingeschraubt sind. Dieser, bzw. diese Schraubenbolzen 16 verlaufen durch jeweils ein weiteres Langloch 17 im Messer 5. Die jeweiligen weiteren Langlöcher 17 sind mit den Langlöchern 14 beim unteren Abschnitt des Rahmens 3 derart ausgerichtet, dass die vorgenannte Schiebebewegung des Messers 5 ermöglicht ist.Reference is now made to FIG. 2, in which a further embodiment is shown. The carding segment is identical to that of FIG. 1, with the exception that the knife support section 4 has a different shape. The knife 5 has pivot pins 26 which protrude into elongated holes 14 in projections 27 of the frame 3, so that a sliding joint 15 is formed. The knife 5 can thus be pivoted on the one hand with the pin 26 in the elongated holes 14 and on the other hand moved towards and away from the drum. Furthermore, the knife 4 is penetrated by screw bolts 16, which are each screwed into a threaded hole 28 in the frame 3. This, or these bolts 16 run through a further elongated hole 17 in the knife 5. The respective further elongated holes 17 are with the elongated holes 14 at lower portion of the frame 3 aligned such that the aforementioned sliding movement of the knife 5 is made possible.

Der Schraubenbolzen 16 kann als Mikrostellschraube ausgebildet sein, wobei mit den Bezugsziffern 29 und 30 Scheiben oder Platten angedeutet sind, über welche das Messer 5 auf dem Schraubenbolzen 16 ein jeweiliges Langloch 17 überbrückend abgestützt ist. Gemäss einer weiteren möglichen Ausführung ist der jeweilige Schraubenbolzen 16 fest im Messertragabschnitt 4 eingeschraubt, wobei die mit den Bezugsziffern 29 und 39 bezeichneten Teile Muttern, bzw. Stellmutter und Gegenmutter, bilden.The screw bolt 16 can be designed as a micro adjusting screw, with the reference numbers 29 and 30 indicating disks or plates, by means of which the knife 5 is supported on the screw bolt 16, bridging a respective elongated hole 17. According to a further possible embodiment, the respective screw bolt 16 is firmly screwed into the knife support section 4, the parts designated by the reference numbers 29 and 39 forming nuts, or adjusting nuts and locknuts.

Entsprechend lässt sich somit die Winkelstellung des Messers 5 relativ zum Tambour einstellen, wobei jeweils eine Schwenkbewegung des Messers 5 um die jeweiligen Zapfen 26 durchgeführt wird.Accordingly, the angular position of the knife 5 relative to the drum can be adjusted, with a pivoting movement of the knife 5 being carried out about the respective pins 26.

Es ist nun ersichtlich, dass die Verschleissteile, d.h. einerseits die Garnituren und andererseits das Messer an Ort und Stelle nachschärfbar und/oder auswechselbar sind. Da die räumliche Entfernung des Messers 5 von den den Kratzenbeschlag bildenden Sägezahnstreifen 2 durch die beschriebene Kombination von Kardiersegment und Schmutzabscheider sehr klein ist, lässt sich eine hochpräzise Einstellung bis zu Abständen von 2/1000 mm des Messers und der Garnituren durchführen, wobei sich eine gegenseitige Abstimmung der Arbeitselemente durchführen lässt, obwohl immer noch ein getrenntes Einstellen ermöglicht ist. Der Hauptträger für sowohl das Kardiersegment als auch den Schmutzabscheider lässt sich äusserst stabil als steifer Maschinenteil mit grosser Masse bauen.It can now be seen that the wearing parts, i.e. on the one hand the sets and on the other hand the knife can be resharpened and / or replaced on the spot. Since the spatial distance of the knife 5 from the sawtooth strips 2 which form the scraper fitting is very small due to the combination of carding segment and dirt separator described, a highly precise setting can be carried out up to distances of 2/1000 mm of the knife and the sets, whereby a mutual Coordination of the work elements can be carried out, although a separate setting is still possible. The main carrier for both the carding segment and the dirt separator can be built extremely stably as a stiff machine part with a large mass.

Als Rahmen 3 und Halter 1 werden hochfeste (hochsteife) extrudierte Aluminiumprofile verwendet. Auch ist es nun möglich, die ganze Einheit, bestehend aus Garnituren, Messer, Schmutzabsaugeraum 6 etc. auf einmal auszuwechseln. Auch können Verschleissteile ausgewechselt werden, z.B. das Messer 5, ohne dass die nichtausgewechselten Teile (in diesem Falle die Kratzenbeschläge) neu eingestellt werden müssen. Die gedrängte Ausführung erlaubt weiter ein kostengünstiges Wechseln und auch Kontrollieren der einzelnen Verschleissteile.High-strength (highly rigid) extruded aluminum profiles are used as frame 3 and holder 1. It is now also possible to replace the entire unit, consisting of trimmings, knives, dirt extraction chamber 6, etc. at once. Wear parts can also be replaced, for example the knife 5, without the non-replaced parts Parts (in this case the scraper fittings) have to be readjusted. The compact design also allows inexpensive changing and also checking of the individual wearing parts.

Als weitere Variante können gemäss der gezeigten, gedrängten Bauform auch Hohlräume 18 bei den Segmenten an den Schmutzabsaugeraum 6 angeschlossen werden. Dazu sind Bohrungen 19 im Rahmen 3 sowie Durchbohrungen 25 beim Absaugeraum vorhanden. Somit kann auch Mikrostaub, der in den Räumen 18 vorhanden ist, abgesogen werden. Bei den gezeichneten Ausführungen ist ein gesondertes Deckblech 22 auf dem Rahmen 3 mittels der Kopfschraube 23 befestigt. Es ist jedoch auch möglich, dieses Deckblech 22 einstückig mit der Wand des rohrförmigen Schmutzabsaugeraumes 6 auszubilden, bzw. eine feste Verbindung zwischen diesen zwei Bauelementen zu erstellen.As a further variant, according to the compact design shown, cavities 18 in the segments can also be connected to the dirt extraction space 6. For this purpose there are bores 19 in the frame 3 and bores 25 in the suction space. Micro dust that is present in rooms 18 can thus also be extracted. In the drawings shown, a separate cover plate 22 is fastened on the frame 3 by means of the cap screw 23. However, it is also possible to form this cover plate 22 in one piece with the wall of the tubular dirt extraction space 6, or to create a firm connection between these two components.
