Abstract

To prevent the accumulation of contaminating matter in the harness of a Jacquard weaving machine, a perforated box is provided at the lower end of the harness. Air is supplied into the box so that it flows vertically upwardly along the harness members and prevents dust, fibers and other contaminating matter from settling on the harness.

Description

An Jacquard-Webmaschinen besteht seit Jahren das Problem der Verstaubung der Niederzüge im unteren Bereich des Webharnisches. Beim Webvorgang setzen sich Flugfasern, Staub und Faserabrieb ab. Diese Verschmutzungen rutschen nach unten und verfilzen. Als Folge davon können die Niederzüge verrotten und zerreissen. Damit verbunden ist eine Beeinträchtigung der Qualität des Weberzeugnisses und schliesslich die Zerstörung des Webharnisches. Dieser muss nämlich in kurzen Abständen - in gewissen Fällen alle sechs Monate - ersetzt werden, was einen Ausfall der Maschine mit sich bringt.Jacquard weaving machines have had the problem of dusting down the drawdowns in the lower part of the weaving harness for years. During the weaving process, flight fibers, dust and fiber abrasion settle. These contaminants slide down and become matted. As a result, the pulldowns can rot and tear. Associated with this is an impairment of the quality of the woven product and ultimately the destruction of the weaving harness. This has to be replaced at short intervals - in certain cases every six months - which leads to a breakdown of the machine.

Mit der Entwicklung von schneller laufenden Maschinen, ab ca. 250 U/Min., wird dieser Verschmutzungseffekt wesentlich gesteigert. Zum schnelleren Lauf kommen grössere Arbeitsbreiten und damit mehr Züge (6 000 bis 20 000 Stück) hinzu, so dass die Verschmutzungen unverhältnismässig hohe Kosten verursachen.With the development of faster running machines, starting at approx. 250 rpm, this pollution effect is significantly increased. In order to run faster, there are larger working widths and thus more trains (6,000 to 20,000 pieces), so that the contamination causes disproportionately high costs.

Zum Reinigen der Maschinen ist es bekannt, mehrmals täglich den Staub mittels Handgebläse seitlich aus dem Harnisch herauszublasen. Die verfilzten Faserteile lassen sich aber dadurch nicht entfernen und müssen periodisch mechanisch entfernt werden. Das periodische Herausblasen führt zu einer Verschmutzung der Umgebung der Maschine und ist auch aus diesem Grund unbefriedigend.To clean the machines, it is known to blow the dust out of the armor laterally several times a day using a hand blower. However, the matted fiber parts cannot be removed as a result and must be periodically removed mechanically. The periodic blowing out pollutes the environment of the machine and is also unsatisfactory for this reason.

Es wurde auch schon versucht, zum Reinigen der Jacquard-Webmaschine grössere Sauggebläse seitlich am Harnisch anzubringen, um die Verschmutzungen sofort bei Anfall zu entfernen. Um effektvoll zu sein, werden sehr hohe Saugleistungen verlang, was einen erheblichen Energieaufwand mit sich bringtAttempts have also already been made to attach larger suction fans to the side of the harness to clean the jacquard weaving machine, in order to remove the dirt immediately in the event of an attack. In order to be effective, very high suction power is required, which entails a considerable amount of energy

Auch die in der CH-PS 584 302 beschriebene pneumatische Reinigungsvorrichtung an einer Webmaschine weist eine mit mehreren Blasdüsen versehene Blaseinrichtung und eine Absaugeinrichtung auf. Dadurch wird Druckluft von unten durch das Webfach geblasen und oberhalb des Webfaches wieder abgesaugt. Zudem sind zusätzliche seitliche Luftströme zur Verbesserung der Reinigungswirkung vorgesehen. Es entstehen jedoch Luftwirbel, so dass einTeil des Staubs nicht in die Absaugeinrichtung gelangt. Vor allem aber wirkt sich im Bereich des Webfaches mit den ständig in Bewegung stehenden Kettfäden die Luftströmung störend für den Webvorgang aus.The pneumatic cleaning device on a weaving machine described in CH-PS 584 302 also has a blowing device provided with a plurality of blowing nozzles and a suction device. As a result, compressed air is blown through the shed from below and extracted again above the shed. In addition, additional lateral air flows are provided to improve the cleaning effect. However, air vortices arise, so that some of the dust does not get into the suction device. Above all, however, in the area of the shed with the warp threads that are constantly in motion, the air flow interferes with the weaving process.

Die Erfindung stellt sich nun zur Aufgabe, ein Verfahren und eine Einrichtung zum Freihalten der Webharflisch-Niederzüge einer Jacquard-Webmaschine von Verschmutzungen zu schaffen, bei welchem die vorgängig erwähnten Nachteile vermieden werden. Zur Lösung dieser Aufgabe weist das erfindungsgemässe Verfahren die im kennzeichnenden Teil des Patentanspruchs 1 angeführten Merkmale auf. Die erfindungsgemässe Einrichtung zur Durchführung dieses Verfahrens ist im Patentanspruch 4 definiert.The object of the invention is now to create a method and a device for keeping the weaving flesh drawdowns of a jacquard weaving machine free of dirt, in which the disadvantages mentioned above are avoided. To achieve this object, the method according to the invention has the features stated in the characterizing part of patent claim 1. The inventive device for performing this method is defined in claim 4.

Durch das erfindungsgemässe Verfahren wird erreicht, dass der Staub vom Webfach nach unten fällt, bis er durch das erzeugte Luftkissen aufgehalten wird. Der Staub und die Verschmutzungen werden durch das Luftkissen in Schwebe gehalten und wandern dann zur Seite, wo sie beispielsweise durch das Ventilationssystem des Raums oder durch eine gegebenenfalls angeordnete Absaugvorrichtung entfernt werden.The inventive method ensures that the dust falls down from the shed until it is stopped by the air cushion generated. The dust and dirt are kept in suspension by the air cushion and then move to the side, where they are removed, for example, by the ventilation system of the room or by an optionally arranged suction device.

Anhand der einzigen Zeichnung, die schematisch den unteren Teil eines Jacquard-Webharnisches darstellt, wird nachfolgend ein Ausführungsbeispiel der Erfindungsgegenstände näher erläutert.An exemplary embodiment of the subject matter of the invention is explained in more detail below with the aid of the single drawing, which schematically represents the lower part of a jacquard weaving harness.

Der Webharnisch-Niederzug der Maschine ist mit 1 bezeichnet. Im Bereich der Kette 3 und des Webfaches, das als Zone 2 angedeutet ist, entstehen beim Webvorgang Verschmutzungen in Form von Flugfasern, Faserabrieb und Staub. Diese Verschmutzungen rutschen den Zügen 4 entlang nach unten und würden, falls sie nicht rechtzeitig entfernt werden, den Harnisch verfilzen. Bei Hochleistungsmaschinen werden häufig Niederzüge 4 aus elastischen Kunstfaserschnüren verwendet, an denen die Staubteilchen infolge elektrostatischer Kräfte zusätzlich haften, was deren Entfernung weiter erschwert.The weaving harness pull-down of the machine is denoted by 1. In the area of the warp 3 and the shed, which is indicated as zone 2, soiling occurs in the form of flight fibers, fiber abrasion and dust during the weaving process. This dirt slides down the cables 4 and, if not removed in time, would matt the harness. In high-performance machines, pull-downs 4 made of elastic synthetic fiber cords are often used, to which the dust particles additionally adhere due to electrostatic forces, which further complicates their removal.

Unterhalb der Befestigung 5 für die Züge 4 befindet sich ein Kasten 6, in welchen Luft eingeblasen wird. Die Luft strömt durch ein Lochblech 7 gleichmässig in den Zügen von unten nach oben und erzeugt im unteren Teil des Harnisches 1 einen leichten Ueberdruck. So entsteht im ganzen unteren Bereich des Harnisches eine gleichmässige, vertikale Luftströmung. Das Niveau dieses « Luftkissens ist in der Zeichnung gestrichelt an der Stelle 8 angedeutet. Der Ueberdruck in den Zügen verhindert das weitere Hinunterrutschen der Verschmutzungen, und diese treten nun seitlich aus und werden von der Luftströmung weggetragen. Dabei muss jedoch beachtet werden, dass die vertikale Luftströmung den Webvorgang nicht stört. Die eingeblasene Luft muss ausreichend filtriert werden. Um die elektrostatische Aufladung der Fasern zu verhindern, sollte befeuchtete oder ionisierte Luft eingeblasen werden.Below the attachment 5 for the trains 4 there is a box 6 into which air is blown. The air flows through a perforated plate 7 evenly in the trains from bottom to top and creates a slight overpressure in the lower part of the urinary compartment 1. This creates a uniform, vertical air flow in the entire lower area of the urinary tract. The level of this air cushion is indicated in dashed lines at position 8 in the drawing. The overpressure in the trains prevents the dirt from slipping down further, and these now emerge from the side and are carried away by the air flow. However, it must be ensured that the vertical air flow does not interfere with the weaving process. The air blown in must be filtered sufficiently. To prevent electrostatic charging of the fibers, humidified or ionized air should be blown in.

Als Folge der Luftströmung ergibt sich unterhalb der Kette 3 eine Ansammlung von Flugstaub und damit verbunden eine Belastung der Kettuntersicht mit Flugfasern. Um dieser Erscheinung entgegenzuwirken, ist es zweckmässig, unterhalb des Webfaches auf beiden Seiten des Harnisches Saugrohre 9 anzubringen. Durch diese Rohre 9 werden die Fasern angesogen und in die Rückluft respektive in eine Entstaubungsanlage abgeführt. Die Absaugrohre verhindern auch eine Verstaubung der Maschinenumgebung.As a result of the air flow, there is an accumulation of fly dust underneath the chain 3 and the associated load on the underside of the chain with fly fibers. In order to counteract this phenomenon, it is expedient to attach suction pipes 9 below the shed on both sides of the harness. The fibers are sucked through these tubes 9 and discharged into the return air or into a dedusting system. The suction pipes also prevent the machine environment from becoming dusty.

Eine weitere Verbesserung besteht darin, den unteren Teil des Harnisches 1 mit einer Verschalung 10 zu versehen, um die in den Zügen 4 nach oben strömende Luft besser zu kanalisieren.Another improvement is to provide the lower part of the urinary cradle 1 with a casing 10 to the in the trains 4 to to better channel air flowing above.
