Abstract

The machine possesses a horizontal roller (1) which is equipped with beating pins (3) and under the underside of which bar grids (4, 5) are arranged. Above the top side of the roller (1) open out at one end of the latter an inlet line (9) and at the other end an outlet line (10) for a stream of conveying air transporting the textile fibres in flock form. Obliquely set guide plates (11) are arranged above the top side of the roller (1) between the mouths of the inlet line (9) and of the outlet line (10). The guide plates (11) limit transfer chambers which move the stream of conveying air further in the direction of the axis of the roller (1). The transfer chambers are connected to an air-permeable and dust-permeable wall (30) which is provided on the right-hand side of the machine, as seen in the Figure, and which is part of a vacuum chamber (20). The machine can consequently separate out of the stream of fibre flocks not only coarser impurities through the bar grids (4, 5), but also fine dust-like impurities which are sucked through the air-permeable and dust-permeable wall (30) into the vacuum chamber (20) and then into the suction line (15). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Reinigungsmaschine für in einem Förderluftstrom transportierte Textilfasern, mit einer liegenden, mit Schlagelementen besetzten Walze, unter deren Unterseite Stabroste angeordnet sind und über deren Oberseite bei einem Ende der Walze ein Einlass und beim anderen Ende ein Auslass für den Förderluftstrom angeordnet ist.The invention relates to a cleaning machine for textile fibers transported in a conveying air stream, with a horizontal roller with impact elements, under the underside of which bar grids are arranged and over the top of which an inlet for the conveying air stream is arranged at one end of the roller and an outlet at the other end is.

Mindestens eine solche Reinigungsmaschine ist bekannt auf dem Markt erhältlich. Sie dient dazu, die im Förderluftstrom zugeführten Faserflocken aufzulösen und Verunreinigungen daraus zu entfernen. Das Fasermaterial wird über die Stabroste geschleppt und auch durch den Aufprall auf die die Überleitkammern begrenzenden Wände gewissermassen geklopft, wodurch Verunreinigungen von dem Material gelöst werden. Gröbere Verunreinigungen, wie z.B. Schalenteile, treten durch die Stabroste hindurch und werden dann abgesaugt. Feine, staubförmige Verunreinigungen verbleiben jedoch in den bekannten Maschinen mindestens teilweise im Förderluftstrom und verlassen dann die Maschine zusammen mit dem vom Förderluftstrom transportierten Fasermaterial.At least one such cleaning machine is known on the market. It serves to dissolve the fiber flakes supplied in the conveying air flow and to remove impurities from them. The fiber material is dragged over the bar gratings and also tapped to a certain extent by the impact on the walls delimiting the transfer chambers, as a result of which contaminants are detached from the material. Coarse contaminants, e.g. Shell parts, pass through the bar grids and are then suctioned off. Fine, dust-like contaminants, however, remain in the known machines at least partially in the conveying air flow and then leave the machine together with the fiber material transported by the conveying air flow.

Die Aufgabe der Erfindung besteht nun darin, die eingangs angegebene Reinigungsmaschine derart auszubilden, dass sie auch feine, staubförmige Verunreinigungen weitgehend von dem Fasermaterial abscheiden kann.The object of the invention is to design the cleaning machine specified at the outset in such a way that it can largely separate even fine, dust-like impurities from the fiber material.

Die Aufgabe ist erfindungsgemäss dadurch gelöst worden, dass nach der Stabrostanordnung, in Förderrichtung der Textilfasern gesehen, eine im wesentlichen senkrechte luft- und staubdurchlässige Wand vorgesehen ist, welche Teil einer Unterdruckkammer ist, an welche eine Saugleitung angeschlossen ist.The object has been achieved according to the invention in that after the bar grate arrangement, seen in the conveying direction of the textile fibers, an essentially vertical air and dust-permeable wall is provided, which is part of a vacuum chamber to which a suction line is connected.

Durch die luft- und staubdurchlässige Wand hindurch kann Luft abgesaugt werden, mit welcher die sehr leichten, staubförmigen Schmutzteilchen aus dem das Fasermaterial transportierenden Förderluftstrom abgeschieden werden können.Air can be drawn off through the air and dust permeable wall, with which the very light, dust-like dirt particles can be separated from the conveying air flow transporting the fiber material.

Die luft- und staubdurchlässige Wand ist beispielsweise ein Sieb oder ein Lochblech mit Löchern von etwa 1,5 mm Durchmesser.The air- and dust-permeable wall is, for example, a sieve or a perforated plate with holes of approximately 1.5 mm in diameter.

Vorzugsweise sind Mittel vorgesehen zum Einstellen des Unterdrucks in der Unterdruckkammer.Means are preferably provided for setting the negative pressure in the negative pressure chamber.

Die in Fig. 1 bis 3 dargestellte Grobreinigungsmaschine besitzt eine Auflösewalze 1, die in einem Gehäuse 2 um eine horizontale Achse drehbar gelagert ist und deren Umfang in üblicher Weise mit Schlagstiften 3 besetzt ist. Die Walze 1 wird im Betrieb von einem nicht dargestellten Antriebsmotor in Pfeilrichtung gemäss Fig. 1 gedreht. Unter der Unterseite der Walze 1 sind zwei nur in Fig. 1 dargestellte Stabroste 4 und 5 angeordnet. Die Oberseite der Walze 1 ist im Abstand vom Walzenumfang mit einer Wand überdeckt, von der ein horizontaler, mittlerer Abschnitt 6 und zwei seitlich an diesen anschliessende, etwa 45° geneigte Seitenabschnitte 7 und 8 vorgesehen sind, im weiteren ist eine an die Wand 7 angrenzende, im wesentlichen senkrechte Wand 30 vorgesehen, welche luft- und staubdurchlässig ist. Die drei Wandabschnitte 6, 7 und 8 sind terrassendachartig angeordnet, das heisst im Querschnitt etwa wie drei Seiten eines gleichschenkligen Trapezes, und je zwei der Wandabschnitte schliessen miteinander jeweils einen Winkel α von etwa 135° ein. Die Wand 30 ist beispielsweise von einem Lochblech mit Löchern von etwa 1,5 mm Durchmesser oder von einem Sieb gebildet. In den Wandabschnitt 7 mündet bei einem Ende der Walze 1 von oben eine Einlassleitung 9, und in den Wandabschnitt 8 mündet beim anderen Ende der Walze 1 eine Auslassleitung 10. Zwischen den Mündungen der Einlassleitung 9 und der Auslassleitung 10 sind über der Oberseite der Walze 1, unterhalb der Wandabschnitte 6, 7, 8, drei zur Achse der Walze 1 schräg gestellte Leitbleche 11, 12 und 13 angeordnet, welche zwei Überleitkammern zwischen der Oberseite der Walze 1 und der Wand mit den Wandabschnitten 6, 7, 8 begrenzen. Die ganze Fläche der luft- und staubdurchlässigen Wand 30 ist Teil einer Unterdruckkammer 20, an welche eine Saugleitung 15 angeschlossen ist.The coarse cleaning machine shown in FIGS. 1 to 3 has an opening roller 1 which is rotatably mounted in a housing 2 about a horizontal axis and the circumference of which is occupied in the usual way with striking pins 3. The roller 1 is rotated in operation by a drive motor, not shown, in the direction of the arrow in FIG. 1. Two bar grids 4 and 5, which are only shown in FIG. 1, are arranged under the underside of the roller 1. The top of the roller 1 is covered at a distance from the circumference of the roller with a wall, of which a horizontal, central section 6 and two laterally adjoining, approximately 45 ° inclined side sections 7 and 8 are provided the wall 7 adjacent, substantially vertical wall 30 is provided, which is permeable to air and dust. The three wall sections 6, 7 and 8 are arranged like a terrace roof, that is to say in cross section approximately like three sides of an isosceles trapezoid, and two of the wall sections each form an angle α of approximately 135 ° with one another. The wall 30 is formed, for example, by a perforated plate with holes of approximately 1.5 mm in diameter or by a sieve. An inlet line 9 opens into the wall section 7 at one end of the roller 1, and an outlet line 10 opens into the wall section 8 at the other end of the roller 1. Between the mouths of the inlet line 9 and the outlet line 10 are above the top of the roller 1 , below the wall sections 6, 7, 8, three baffles 11, 12 and 13 arranged obliquely to the axis of the roller 1, which delimit two transfer chambers between the top of the roller 1 and the wall with the wall sections 6, 7, 8. The entire surface of the air- and dust-permeable wall 30 is part of a vacuum chamber 20, to which a suction line 15 is connected.

Im Betrieb werden der Grobreinigungsmaschine zu reinigende und aufzulösende Textilfasern in Flockenform in einem Förderluftstrom durch die Einlassleitung 9 zugeführt. Die Förderluft mit den Faserflocken strömt im wesentlichen zunächst um die Unterseite der drehenden Walze 1 herum, dann durch die Überleitkammer zwischen den Leitblechen 11 und 12, welche die Luft in Richtung der Achse der Walze 1 weiterbewegt, dann wieder um die Unterseite der Walze, dann durch die Überleitkammer zwischen den Leitblechen 12 und 13 und wieder um die Unterseite der Walze 1, um die Maschine schliesslich durch die Auslassleitung 10 zu verlassen. Beim Herumlaufen um die Unterseite der Walze 1 werden die Faserflocken durch die Schlagstifte 3 bearbeitet und zunehmend aufgelöst, und Verunreinigungen werden von den Fasern getrennt. Die gröberen Verunreinigungen, wie z.B. Schalenteile, werden durch die Stabroste 4 und 5 hindurch abgeschieden und aus dem Raum unter den Stabrosten durch eine nicht dargestellte Absaugeinrichtung abgesaugt. Danach fliegen die Faserflocken jeweils nach oben in die nächstfolgende Überleitkammer, wo sie durch Aufprallen auf die Wandabschnitte 6, 7, 8 weiter gelockert und gewendet werden. Feine, staubförmige Verunreinigungen, die von den Fasern getrennt worden sind, können höchstens teilweise durch die Stabroste 4 und 5 hindurch abgesaugt werden, während ein grosser Teil des Staubes im Förderluftstrom verbleibt. Die luft- und staubdurchlässige Wand 30, die Unterdruckkammer 20 und die Saugleitung 15 dienen dazu, auch diese feinen Verunreinigungen vom Förderluftstrom zu trennen, so dass sie nicht am Ende mit diesem und den Fasern durch die Auslassleitung 10 austreten können. Die Saugleitung 15 ist an eine nicht dargestellte Unterdruckquelle bzw. Absaugeinrichtung angeschlossen, welche mit Staub beladene Luft durch die Wand 30 hindurch absaugt.In operation, the coarse cleaning machine is supplied with textile fibers to be cleaned and dissolved in flake form in a conveying air flow through the inlet line 9. The conveying air with the fiber flakes essentially flows first around the underside of the rotating roller 1, then through the transfer chamber between the guide plates 11 and 12, which moves the air in the direction of the axis of the roller 1, then again around the underside of the roller, then through the transfer chamber between the guide plates 12 and 13 and again around the underside of the roller 1 to finally leave the machine through the outlet line 10. When running around the underside of the roller 1, the flakes of fiber are processed and increasingly dissolved by the striking pins 3, and impurities are separated from the fibers. The coarser impurities, such as shell parts, are separated through the bar grids 4 and 5 and out of the space under the bar grids by a suction device, not shown. Then the fiber flakes fly upwards into the next transfer chamber, where they are further loosened and turned by hitting the wall sections 6, 7, 8. Fine, dust-like impurities which have been separated from the fibers can at most be partially sucked off through the bar grids 4 and 5, while a large part of the dust remains in the conveying air flow. The air- and dust-permeable wall 30, the vacuum chamber 20 and the suction line 15 serve to separate these fine impurities from the conveying air flow, so that they cannot ultimately exit through the outlet line 10 together with the fibers. The suction line 15 is connected to a vacuum source or suction device, not shown, which sucks dust-laden air through the wall 30.

Die Grösse des in der Unterdruckkammer 20 erzeugten Unterdrucks bzw. des durch die Wand 30 hindurch abgesaugten Luftstroms ist einstellbar, beispielsweise dadurch, dass die Unterdruckquelle bzw. Absaugeinrichtung einstellbar ist, oder dadurch, dass in der Saugleitung 15 ein einstellbares Drosselorgan, z.B. wie gezeichnet eine einstellbare Drosselklappe 16, angeordnet ist. Der Luftstrom wird so eingestellt, dass er ausreicht, um den Staub durch die Leitung 15 abzusaugen, so dass sich der Staub nicht auf der Unterseite der Unterdruckkammer ablagert. Um das beobachten zu können, sind an einer Aussenwand 21, z.B. wie in den Figuren gezeigt, Sichtfenster 17 vorgesehen. Es kann ferner zweckmässig sein, der Unterdruckkammer 20 wenigstens einen Spüllufteinlass 18 anzuordnen, durch welchen aus der Umgebung Spülluft in die Unterdruckkammer 20 gesaugt werden kann. Der Spüllufteinlass 18 enthält ebenfalls ein einstellbares Drosselorgan, z.B. eine Drosselklappe 19 (Fig. 4).The size of the vacuum generated in the vacuum chamber 20 or of the air flow sucked through the wall 30 is adjustable, for example by the vacuum source or suction device being adjustable, or by the fact that an adjustable throttle element, for example as shown, is set in the suction line 15 adjustable throttle valve 16 is arranged. The air flow is adjusted so that it is sufficient to suction the dust through the line 15, so that the dust is not deposited on the underside of the vacuum chamber. In order to be able to observe this, viewing windows 17 are provided on an outer wall 21, for example as shown in the figures. It can furthermore be expedient to arrange the vacuum chamber 20 at least one purge air inlet 18, through which purge air can be drawn into the vacuum chamber 20 from the surroundings. The purge air inlet 18 also contains an adjustable throttle element, for example a throttle valve 19 (FIG. 4).

Die Innenseite der luft- und staubdurchlässigen Wand 30 wird durch den Förderluftstrom bzw. durch die von diesem transportierten Faserflocken stets sauber gehalten. Wenn die Wand 30 perforiert ist, dann sollten die Löcher an der Innenseite der Wand keine scharfen Kanten aufweisen, damit an diesen Kanten keine Fasern oder Verunreinigungen hängen bleiben können. Die Wand 30 kann zweckmässig von einem Lochblech gebildet sein, das an der Innenseite einen galvanischen Überzug aufweist. Der Überzug erstreckt sich dann - mit einer gerundeten Oberfläche - etwas in die Löcher hinein.The inside of the air and dust-permeable wall 30 is always kept clean by the conveying air flow or by the fiber flakes transported by it. If the wall 30 is perforated, then the holes on the inside of the wall should not have any sharp edges so that fibers or contaminants cannot get caught on these edges. The wall 30 can expediently be formed by a perforated plate which has a galvanic coating on the inside. The coating then extends - with a rounded surface - somewhat into the holes.

In einer in Fig. 4 gezeigten Variante besteht die Möglichkeit, die Unterdruckkammer 20 in mehrere, beispielsweise 3, Unterdruckkammern 20.1, 20.1, 20.3 zu unterteilen und jeder Unterdruckkammer ein Absaugrohr mit einer Drosselklappe zuzuordnen. Die Drosselklappen sind mit 16.1, 16.2 und 16.3 gekennzeichnet.In a variant shown in FIG. 4, it is possible to subdivide the vacuum chamber 20 into a plurality, for example 3, of vacuum chambers 20.1, 20.1, 20.3 and to assign a suction pipe with a throttle valve to each vacuum chamber. The throttle valves are marked 16.1, 16.2 and 16.3.

Die Unterdruckkammern 20.1, 20.2, und 20.3 können, wie in Fig. 4 dargestellt, die Frischlufteintrittsöffnung oder Spüllufteintrittsöffnung 18 mit der Drosselklappe 19 als gemeinsame Spülluftöffnung zugeordnet haben, so dass ein Spülluftzutritt zu allen drei Kammern möglich ist. Es besteht selbstverständlich auch die Möglichkeit, jeder Kammer eine eigene Spülluftleitung zuzuordnen mit einem entsprechenden Drosselventil.The vacuum chambers 20.1, 20.2, and 20.3 can, as shown in FIG. 4, have assigned the fresh air inlet opening or purge air inlet opening 18 with the throttle valve 19 as a common purge air opening, so that purge air can be accessed to all three chambers. Of course, there is also the option of assigning each chamber its own purge air line with a corresponding throttle valve.

Die Unterteilung hat den Vorteil, dass die Luftströmung pro Abschnitt gleichmässiger gestaltet werden kann als mit einem ursprünglich gezeigten Querabzug.The subdivision has the advantage that the air flow per section can be made more uniform than with a cross extractor originally shown.

Letztlich besteht auch die Möglichkeit, die Wandstärke d der Wand 30 derart zu wählen, dass diese Wandabschnitte im Betrieb durch den Aufprall des im Förderluftstrom transportierten Fasermaterials in Vibrationen versetzt wird.Ultimately, there is also the possibility of choosing the wall thickness d of the wall 30 in such a way that, during operation, these wall sections are vibrated by the impact of the fiber material transported in the conveying air flow.
