Abstract

Die vorliegende Erfindung bezieht sich auf einen Messerrost für eine dem Reinigen von Fasern dienenden und mit einer Garnitur versehenen Öffnungswalze (12). Jedes der Messer (16) trägt ein sich über seine Länge erstreckendes Leitelement, welches ein Leitblech (25) umfaßt, dessen Abstand von der Garnitur einstellbar ist. Zum Zwecke der Einstellung umfaßt das Leitelement einen ebenen Bandteil (24), welcher auf einer Breitseite (26) des Messers (16) aufliegt, parallel zur Breitseite (26) verschiebbar und am Messer (16) lösbar befestigbar ist. Bei den bekannten Einrichtungen ist das Einstellen des Abstandes x des Leitbleches (25) von der Garnitur schwierig, weil die Zugänglichkeit zu der zu messenden Stelle beschwerlich ist. Gemäß der Erfindung soll dies dadurch vermieden werden, daß jedes der Leitelemente an der dem Leitblech (25) abgewandten Längsseite des ebenen Bandteils (24) zusätzlich einen sich in der Längsrichtung seines Messers (16) erstreckenden, dessen Rücken überdeckenden und zum ebenen Bandteil (24) abgewinkelten weiteren Bandteil (28) aufweist.The present invention relates to a knife grate for an opening roller (12) used for cleaning fibers and provided with a clothing. Each of the knives (16) carries a guide element extending over its length, which comprises a guide plate (25), the distance of which from the set can be adjusted. For the purpose of adjustment, the guide element comprises a flat band part (24) which rests on a broad side (26) of the knife (16), can be displaced parallel to the broad side (26) and can be detachably fastened to the knife (16). In the known devices, the adjustment of the distance x of the guide plate (25) from the set is difficult because the accessibility to the point to be measured is difficult. According to the invention, this is to be avoided in that each of the guide elements on the longitudinal side of the flat band part (24) facing away from the guide plate (25) additionally extends in the longitudinal direction of its knife (16), its back covering and towards the flat band part (24 ) has angled further band part (28).

Description

Die vorliegende Erfindung bezieht sich auf einen aus einzelnen Messern bestehenden Messerrost für eine mit einer Garnitur ausgerüsteten, rotierbaren Oeffnungswalze, bei welchem Rost an jedem der Rostmesser ein aus flächenhaftem Material gebildetes und sich über die Länge des Messers erstreckendes Leitelement befestigt ist, welches zwei sich in der Längsrichtung des Messers erstreckende, nebeneinander angeordnete Bandteile umfasst, von denen der erste Bandteil eine ebene Fläche bildet, welche an einer Breitseite des ihm zugeordneten Messers anliegt und der zweite Bandteil eine der Garnitur benachbarte und zu dieser in ungefähr tangentialer Richtung verlaufende Leitfläche bildet, deren Abstand von der Garnitur durch Verschieben des Leitelementes parallel zur erwähnten Seitenfläche einstellbar ist.The present invention relates to a knife grate consisting of individual knives for a rotatable opening roller equipped with a set, in which grate is attached to each of the grate knives a sheet-like material which extends over the length of the knife and which is two in one the longitudinal direction of the knife extends, arranged side by side band parts, of which the first band part forms a flat surface which rests on a broad side of the knife assigned to it and the second band part forms a guide surface adjacent to the set and running in an approximately tangential direction, the latter Distance from the set can be adjusted by moving the guide element parallel to the side surface mentioned.

Durch die deutsche Patentschrift Nr. 16 85 571 ist ein solcher Messerrost an einer Reinigungsmaschine für Baumwollfasern bekannt, bei welchem die Messer mit Leitblechen versehen sind, welche in ihrer Entfernung zu einem Schläger verstellbar sind. Jedes der Leitbleche weist eine Leitfläche auf und besitzt einen ebenen Teil, welcher auf der dem Schläger zugekehrten Breitseite seines zur tangentialen Richtung des Schlägermantels schräg stehenden Messers aufliegt.Such a knife grate on a cotton fiber cleaning machine is known from German Patent No. 16 85 571, in which the knives are provided with guide plates which can be adjusted in their distance from a racket. Each of the baffles has a guide surface and has a flat part, which rests on the broad side facing the racket of its knife, which is inclined to the tangential direction of the racket shell.

Für ein einwandfreies-Ausscheiden der Verunreinigungen aus dem Fasermaterial sind die Abstände der Leitbleche vom Schläger von grosser Bedeutung. Es ist somit wich--tig, dass diese genau eingestellt werden können. Durch vorliegende Erfindung soll die Genauigkeit der Einstellung verbessert und vor allem das Ausführen einer exakten Einstellung erleichtert werden. Die.Erfindung ist dadurch gekennzeichnet, dass jedes der Leitelemente an der dem zweiten Bandteil abgewandten Längsseite des ersten Bandteils einen sich in der Längsrichtung seines Messers erstreckenden und dessen Rücken mindestens teilweise überdeckenden, zum ersten Bandteil abgewinkelten, dritten Bandteil aufweist.The distances between the guide plates and the racket are of great importance for the impeccable removal of the impurities from the fiber material. It is therefore important that these can be set precisely. The present invention is intended to improve the accuracy of the setting and, above all, to make it easier to carry out an exact setting. The invention is characterized in that each of the guide elements on the long side of the first band part facing away from the second band part has a third band part which extends in the longitudinal direction of its knife and at least partially covers its back and is angled to the first band part.

Durch das Vorsehen der abgewinkelten Bandteile werden leicht zugängliche zu messende Stellen erhalten. Dadurch wird die Genauigkeit des Einstellens merklich erhöht. Als Folge der abgewinkelten, dritten Bandteile ergibt sich als zusätzlicher Vorteil eine Verbesserung der Stabilität der Leitelemente und damit auch der Stabilität der die Leitelemente tragenden Messer. Ausserdem können die Leitelemente in der Weise geformt werden, dass bei in Anschlag mit den Messerrücken befindlichen, dritten Bandteilen die Leitflächen, d.h. die zweiten Bandteile, in äusserste Nähe der Garnitur zu liegen kommen, eine Berührung dieser Teile und damit eine Beschädigung derselben aber trotzdem unter allen Umständen vermieden ist.By providing the angled band parts, easily accessible places to be measured are obtained. This noticeably increases the accuracy of the setting. As a result of the angled, third band parts, there is an additional advantage of improving the stability of the guide elements and thus also the stability of the knives carrying the guide elements. In addition, the guide elements can be shaped in such a way that when the third band parts are in abutment with the knife back, the guide surfaces, i.e. the second parts of the belt come to lie very close to the clothing, touching these parts and thus damaging them is nevertheless avoided under all circumstances.

Im folgenden sei die.Erfindung.anhand eines Ausführungsbeispiels und der Zeichnung näher erläutert. In der letzteren ist

  • Fig. 1 ein Querschnitt durch eine Reinigungsmaschine und
  • Fig. 2 ein Querschnitt eines Messers und des ihm zugeordneten Leitelementes.
The invention is explained in more detail below using an exemplary embodiment and the drawing. In the latter is
  • Fig. 1 shows a cross section through a cleaning machine and
  • Fig. 2 shows a cross section of a knife and the guide element assigned to it.

Gemäss Fig. 1 dient eine durch die beiden Förderwalzen 11 gebildete Zuführungseinrichtung zum Zuführen von Fasermaterial zur Oeffnungswalze 12. Auf deren zylindrischer Mantelfläche ist eine Garnitur 13 angebracht,. welche aus Zähnen gebildet ist. Die Walze 12 ist im durch den Pfeil 14 angegebenen Drehsinn.um ihre Achse 15 rotierbar. Messer 16 werden beidendig von je einem Rahmen getragen, von denen in Fig. 1 der Rahmen 17 sichtbar ist. Die Rahmen sind um die Welle 18 schwenkbar. Die Gesamtheit der Messer 16 bildet einen Messerrost. Jedem Messer 16 ist ein Leitelement 19 zugeordnet. Ein Teil der Garnitur 13 ist von einem Leitblech 20 bedeckt. Eine Klappe 21 erstreckt sich von einem Absaugkanal 22 weg und an der Oeffnungswalze 12 vorbei. Ausserdem ist eine Abschirmwand 23 vorgesehen. Die Teile 11, 16, 19, 20, 21 und 23 erstrecken sich in Richtung der Achse 15 über die gesamte Länge der Walze 12.According to FIG. 1, a feed device formed by the two conveyor rollers 11 is used to feed fiber material to the opening roller 12. A clothing 13 is attached to its cylindrical outer surface. which is made up of teeth. The roller 12 is rotatable about its axis 15 in the direction of rotation indicated by the arrow 14. Knives 16 are carried at both ends by a frame, of which the frame 17 is visible in FIG. 1. The frames are pivotable about the shaft 18. The entirety of the knives 16 forms a knife grate. A guide element 19 is assigned to each knife 16. A part of the set 13 is covered by a baffle 20. A flap 21 extends away from a suction channel 22 and past the opening roller 12. A shielding wall 23 is also provided. The parts 11, 16, 19, 20, 21 and 23 extend in the direction of the axis 15 over the entire length of the roller 12.

Die Leitelemente 19 der Fig. 1 umfassen, wie in Fig. 2 gezeigt ist, einen ersten Bandteil 24 und einen zweiten Bandteil 25. Diese Bandteile 24 und 25 erstrecken sich in Richtung der Achse 15 über die gesamte Länge der Oeffnungswalze 12. Jedes der Messer 16 steht zur (nicht gezeichneten) Tangente an die Garnitur 13 bzw. Mantelfläche der Oeffnungswalze 12 schräg. Der erste Bandteil 24 ist von ebener Form und liegt auf der der Oeffnungswalze 12 zugekehrten Breitseite 26 des Messers 16 auf. Die Leitelemente 19 sind mittels Schrauben 27 an den Messern 16 befestigt. Bei gelöster Schraube 27 ist das Leitelement 19 in Richtung quer zu seiner Längsrichtung und parallel zur Breitseite 26, welche der Garnitur 13 zugekehrt ist, beliebig verschiebbar. Es kann mittels der Schraube 27 in beliebigen Positionen fixiert und damit der in Fig. 2 gezeigte, zwischen dem zweiten Bandteil 25 und der Garnitur 13 vorhandene Abstand x-beliebig gewählt und eingestellt werden.The guide elements 19 of FIG. 1 comprise, as shown in FIG. 2, a first belt part 24 and a second belt part 25. These belt parts 24 and 25 extend in the direction of the axis 15 over the entire length of the opening roller 12. Each of the knives 16 is to the (not shown) tangent to the clothing 13 or jacket surface of the opening roller 12 obliquely. The first band part 24 is of flat shape and lies on the broad side 26 of the knife 16 facing the opening roller 12. The guide elements 19 are fastened to the knives 16 by means of screws 27. When the screw 27 is loosened, the guide element 19 can be moved as desired in the direction transverse to its longitudinal direction and parallel to the broad side 26, which is facing the set 13. It can be fixed in any position by means of the screw 27 and thus the distance shown between the second band part 25 and the clothing 13 shown in FIG. 2 can be selected and set as desired.

Im Betrieb der gezeigten Reinigungsmaschine wird das zu reinigende Fasermaterial mittels der Förderwalzen 11 der Garnitur 13 zugeführt und dabei bei sich in Rotation befindlicher Oeffnungswalze 12 von deren Zähnen mitgenommen. Dabei werden die im Fasermaterial vorhandenen Verunreinigungen, wie Körnchen, Staubteilchen und dergl. durch die Fliehkraft nach aussen geschleudert und unter Mitwirkung der Messer 16 und Leitelemente 19 von den in dieser Arbeitsphase an den Zähnen der Garnitur 13 hängenden Fasern getrennt. Anschliessend löst sich im Bereich der Klappe 21 als Folge des vom Absaugkanal 22 erzeugten Unterdrucks und der Abschirmwand 23 das Fasermaterial von der Garnitur 13 ab und gelangt durch den Kanal 22 zur nächsten Verarbeitungsstufe.In the operation of the cleaning machine shown, the fiber material to be cleaned is fed to the clothing 13 by means of the conveyor rollers 11 and is carried along by the teeth of the teeth when the opening roller 12 is rotating. The impurities present in the fiber material, such as granules, dust particles and the like are flung outwards by centrifugal force and separated with the cooperation of the knives 16 and guide elements 19 from the fibers hanging from the teeth of the clothing 13 in this working phase. The fiber material then detaches from the clothing 13 in the area of the flap 21 as a result of the negative pressure generated by the suction channel 22 and the shielding wall 23 and passes through the channel 22 to the next processing stage.

Der zweite Bandteil 25 verläuft mindestens ungefähr tangential zur Garnitur 13 und bildet für das Fasermaterial ein Leitblech. Die Erfahrung hat gezeigt, dass zum optimalen Entfernen der Verunreinigungen aus den Fasern die Lage des zweiten Bandstückes 25, insbesondere dessen Abstand x von der Garnitur 13, von ausschlaggebender Bedeutung ist. Bei den heutigen Maschinen ist das genaue Einstellen eines vorgegebenen Wertes von x sehr beschwerlich, da die Zugänglichkeit zum Zwischenraum zwischen dem Bandteil 25 und der Garnitur 13 behindert und die Sicht auf diesen Zwischenraum schlecht ist. Um diese Nachteile zu beheben, weist das Leitelement 19 erfindungsgemäss auf seiner von der Garnitur 13 abgewandten Seite zusätzlich einen dritten Bandteil 28 auf. Dieser ist zum ersten Bandteil 24 abgewinkelt und überdeckt den Rücken des Messers 16 mindestens teilweise. Im gezeigten Beispiel sind der Bandteil 28 und der Messerrücken parallel zueinander. Ihr gegenseitiger Abstand ist mit y bezeichnet. Die Entfernung y kann viel leichter und genauer gemessen werden als die Distanz des Bandteiles 25 von der Garnitur 13, so dass mühsame und beschwerliche Einstellungen eliminiert sind.The second band part 25 extends at least approximately tangentially to the clothing 13 and forms a guide plate for the fiber material. Experience has shown that in order to optimally remove the impurities from the fibers, the position of the second band piece 25, in particular in particular, its distance x from the clothing 13 is of crucial importance. In today's machines, the exact setting of a predetermined value of x is very difficult because the access to the space between the belt part 25 and the clothing 13 hinders and the view of this space is poor. To overcome these disadvantages, the guide element 19 according to the invention additionally has a third band part 28 on its side facing away from the clothing 13. This is angled to the first band part 24 and at least partially covers the back of the knife 16. In the example shown, the band part 28 and the knife back are parallel to one another. Their mutual distance is denoted by y. The distance y can be measured much more easily and precisely than the distance of the band part 25 from the clothing 13, so that tedious and arduous adjustments are eliminated.

Die Breiten der ersten Bandteile 24 der Leitelemente 19 werden vorteilhafterweise in der Weise bemessen, dass bei mit dem Messerrücken in Anschlag befindlichem, drittem Bandteil 28 ein minimaler Abstand des zweiten Bandteiles 25 von den Spitzen der Garnitur 13 gerade noch vorhanden ist. Auf diese Weise ist ein Anschlagen von Teilen der Garnitur 13 an das Bandstück 25 und sind damit gegenseitige Beschädigungen dieser Teile unter allen Umständen vermieden.The widths of the first band parts 24 of the guide elements 19 are advantageously dimensioned in such a way that when the third band part 28 is in contact with the back of the knife, there is just a minimal distance between the second band part 25 and the tips of the clothing 13. In this way, striking parts of the clothing 13 on the band piece 25 and mutual damage to these parts are avoided under all circumstances.

Das Einstellen eines gewünschten Abstandes y kann mit einem Massstab ausgeführt werden. Ein solcher Abstand kann aber auch durch Einschieben einer Dickenlehre zwischen dem Rücken des Messers 16 und dem Bandteil 28 eingestellt werden. Dabei ist die Veränderung der Distanz x als Funktion der Veränderung der Distanz y vom von den Bandstücken 24 und 25 eingeschlossenen Winkel abhängig.A desired distance y can be set on a scale. Such a distance can also be achieved by inserting a thickness gauge between the back of the knife 16 and the band part 28 can be set. The change in the distance x as a function of the change in the distance y depends on the angle enclosed by the band pieces 24 and 25.

Während eine parallele Lage des dritten Bandteils 28 zum Messerrücken im allgemeinen eine erwünschte Ausführungsform sein wird, sind für besondere Fälle auch andere Ausgestaltungen und Formgebungen dieser Teile möglich. Bei der gezeigten Ausführungsform erstrecken sich die Messer 16 zwischen den schwenkbaren Rahmen 17 und sind an diesen befestigt und von diesen getragen. Es ist ersichtlich, dass als ein weiterer Vorteil der Erfindung der abgewinkelte Bandteil 28 eine zusätzliche Festigkeit des Leitelementes 19 bedingt, welche sich auch im Sinne einer Verstärkung der Festigkeit des Messers 16 auswirkt.While a parallel position of the third band part 28 to the back of the knife will generally be a desired embodiment, other configurations and shapes of these parts are also possible for special cases. In the embodiment shown, the knives 16 extend between the pivotable frames 17 and are fastened to and supported by them. It can be seen that, as a further advantage of the invention, the angled band part 28 requires an additional strength of the guide element 19, which also has the effect of increasing the strength of the knife 16.
