Description

Die vorliegende Erfindung betrifft eine Einrichtung zum kon­tinuierlichen Reinigen von Materialbahnen, insbesondere Pa­pier- oder Gewebebahnen, bei welchem die Warenbahn kontinu­ierlich an Luft-Ansaugmittel vorbeibewegbar ist, wobei sich die Luft-Ansaugmittel über die ganze Breite der Warenbahn er­strecken und mit einem Luft-Ansaugkanal in Strömungsverbin­dung stehen.The present invention relates to a device for the continuous cleaning of material webs, in particular paper or fabric webs, in which the material web is continuously movable past air suction means, the air suction means extending over the entire width of the material web and with an air suction channel in Flow connection.

Es ist allgemein bekannt, dass bahnenförmige Halbfabrikate, etwa aus Papier, aus Kunststoff, aus Geweben oder auch aus Edelmetallen vor ihrer Weiterbehandlung von Staub, Schmutz und Flusen sorgfältig zu befreien sind, um beispielsweise Fehldrucke in der Druckerei, Verschmutzen von Behandlungs­bädern in der Ausrüsterei etc. zu vermeiden.It is generally known that sheet-like semifinished products, e.g. made of paper, plastic, fabrics or even precious metals, must be carefully cleaned of dust, dirt and fluff before they are further processed, in order to avoid, for example, misprints in the printing shop, contamination of treatment baths in the finishing shop, etc. . to avoid.

Die hierfür bisher zur Anwendung gelangenden Entstaubungs-­Einrichtungen, insbesondere mit Schlitzdüsen, sind allerdings nicht in der Lage, den steigenden Anforderungen an den Ent­staubungsgrad gerecht zu werden. Wenn zum Beispiel eine Ge­webebahn mit einem Vorschub von 60m/min. über einen Absaug­schlitz von 20 mm Breite bewegt wird, dann beträgt die Ein­wirkungszeit des Luftstromes etwa 0,02 sec. Die reicht nur selten für eine wirksame Reinigung und ist u.a. für beflockte Warenbahnen absolut unbrauchbar.The dedusting devices used to date, in particular with slotted nozzles, have not been able to meet the increasing requirements for the degree of dedusting. If, for example, a fabric web with a feed of 60m / min. is moved over a suction slot of 20 mm width, then the exposure time of the air flow is about 0.02 sec. This is rarely enough for effective cleaning and is among other things absolutely useless for flocked webs.

Aufgabe der Erfindung ist deshalb die Schaffung einer Ein­richtung der vorgenannten Art, welche trotz hoher Vorschub­geschwindigkeit der Warenbahn eine lange Einwirkungszeit des Luftstromes und so eine optimale Reinigung gewährleistet.The object of the invention is therefore to provide a device of the aforementioned type which, despite the high feed rate of the web, ensures a long exposure time of the air flow and thus optimal cleaning.

Dies wird erfindungsgemäss dadurch erreicht, dass die mit dem Luft-Ansaugkanal in Strömungsverbindung stehenden Luft-­Ansaugmittel Diffusoren sind, von welchen eine Mehrzahl in Bewegungsrichtung der Warenbahn hintereinander sowie eine Mehrzahl nebeneinander angeordnet sind und diese in einer gemeinsamen, zur Warenbahn parallelen Ebene ausmünden, wobei sich zur Erzeugung eines Breithalteeffektes in der Mündungs­ebene der Diffusoren eine Mehrzahl, der Auflage der Waren­bahn dienende, gitterartig angeordnete Stäbe in Bewegungs­richtung der Warenbahn zur Mitte der Warenbahn hin schrägver­laufend erstrecken, und wobei zur Bildung einer sehr gross­ flächigen Ansaug-Mündungsebene drei Diffusoren zueinander symmetrisch hintereinander angeordnet sind und in der Mün­dungsebene trichterförmig ausmünden, wobei die beiden äusse­ren Diffusoren eine Umlenkung von etwa 90° aufweisen.This is achieved according to the invention in that the air suction means which are in flow connection with the air suction duct are diffusers, of which a plurality are arranged one behind the other in the direction of movement of the material web and a plurality are arranged next to one another and open out in a common plane parallel to the material web, wherein a plurality of bars serving to support the web, arranged in a lattice-like manner, extend obliquely in the direction of movement of the web toward the center of the web to produce a spreading effect in the mouth plane of the diffusers, and to form a very large one flat suction mouth plane, three diffusers are arranged symmetrically one behind the other and open out in a funnel shape in the mouth plane, the two outer diffusers having a deflection of approximately 90 °.

Durch diese Massnahmen wird eine Einrichtung zum kontinuier­lichen Reinigen von Materialbahnen mit hoher Reinigungswir­kung unter gleichzeitigem Breithalten der Warenbahn ohne Zu­satzmittel erreicht.These measures achieve a device for the continuous cleaning of material webs with a high cleaning effect while at the same time keeping the material web wide without additives.

Hierbei ist es von Vorteil, wenn die gitterartig angeordneten Stäbe bezüglich ihrer Schrägstellung verstellbar an einem Rahmen abgestützt sind und wenn vom Rahmen ausserhalb der Stäbe zwei, sich über die ganze Breite der Einrichtung er­streckende, die Auflageebene der Stäbe für die Warenbahn überragende, der Führung der Warenbahn dienende Lineale ab­ragen.It is advantageous if the bars arranged in a grid-like manner are supported on a frame with respect to their inclination and if the frame outside the bars has two, extending over the entire width of the device, superior to the support plane of the bars for the web, guiding the Remove the rulers that serve the web.

Je nach Anwendung können dabei die Stäbe auflageseitig der Warenbahn als Schaber oder Bürsten ausgebildet sein.Depending on the application, the rods can be designed as scrapers or brushes on the support side of the web.

Auf diese Weise wird die Warenbahn 5 grossflächig angeströmt, was einen optimalen Reinigungseffekt bewirkt.In this way, the fabric web 5 is flowed over a large area, which causes an optimal cleaning effect.

Weiter ist erfindungswesentlich, dass sich in der Mündungs­ebene 7 der Diffusoren 2,3,4 eine Mehrzahl, der Auflage der Warenbahn 5 dienende, gitterartig angeordnete Stäbe 6 und 8 in Bewegungsrichtung der Warenbahn zur Mitte der Warenbahn hin schrägverlaufend erstrecken.It is also essential to the invention that a plurality of bars 6 and 8, arranged in the manner of a grid and serving to support the web 5, extend obliquely in the direction of movement of the web toward the center of the web in the mouth plane 7 of the diffusers 2, 3, 4.

Diese Massnahmen bewirken einen Breithalteeffekt auf die Wa­renbahn, ohne hierfür weitere Massnahmen treffen zu müssen.These measures have a wide-ranging effect on the web without having to take any further measures.

Vorteilhaft ist dabei, wenn die gitterartig angeordneten Stäbe 6,8 bezüglich ihrer Schrägstellung verstellbar an einem Rahmen 9 abgestützt sind.It is advantageous if the bars 6, 8 arranged in a lattice arrangement are supported on a frame 9 so as to be adjustable with respect to their inclined position.

Die Verstellung kann dabei von Hand oder über einen Hydrau­likschieber 11 oder über nicht näher gezeigte motorgetriebene Spindelmittel erfolgen.The adjustment can be carried out by hand or via a hydraulic slide 11 or via motor-driven spindle means, not shown.

Zudem können an der den Stäben gemeinsamen Stellachse- oder Spindel 12 Vibrator-Mittel 13 angreifen, welche den Reini­ gungseffekt zusätzlich erhöhen.In addition, 12 vibrator means 13 can engage on the actuating axis or spindle common to the rods, which the Reini additional effect.

Weiter ist vorteilhaft, wenn vom Rahmen 9 ausserhalb der Stäbe 6,8 zwei, sich über die ganze Breite der Einrichtung erstreckende, die Auflageebene der Stäbe 6,8 für die Waren­bahn 5 überragende, der Führung der Warenbahn dienende Line­ale 16 abragen.It is also advantageous if two rulers 16 extend from the frame 9 outside of the bars 6, 8, which extend over the entire width of the device and extend beyond the support plane of the bars 6, 8 for the web 5, and serve to guide the web.

Je nach Verwendung der erfindungsgemässen Einrichtung ist es von Vorteil, wenn die Stäbe 6,8 auflageseitig der Warenbahn als Schaber oder Bürsten ausgebildet sind, was den Reinigungs­effekt weiter erhöht.Depending on the use of the device according to the invention, it is advantageous if the bars 6, 8 are designed as scrapers or brushes on the support side of the web, which further increases the cleaning effect.

Aus dem Vorbeschriebenen ergibt sich nun eine Einrichtung zum kontinuierlichen Reinigen von Materialbahnen, welche ge­eignet ist, allen heutigen Qualitäts- und Effektivansprüchen zu genügen.From the above, there is now a device for the continuous cleaning of material webs, which is suitable to meet all today's quality and effective requirements.
