Description

Schutzvorrichtung für die Walzen von Reibmühlen und anderen Maschinen. Gegenstand oder Erfindung ist eine Verbesserung der Schutzvorrichtung für die Walzen von Reibmühlen und anderen Maschinen nach Patent 3¢3368, insbesondere für Mahl- und Schleifmaschinen, Misch- und Waschvorrichtungen und Kalender u. dgl. Die Verbenerung besteht in der Art der Befestigung der Schutzglielder an Aden seitlichen Endstücken, um sie leicht einstellbar zu machen zwecks Anpassung einerseits an verschi(zden starkes Arbeitsgut und andererseits an die Körpergröße des die Maschine betdienenden Arbeiters. Zu dem Zwecke ist gemäß der Erfindung das Schutzglied nicht mehr wie beim Gegenstande des Hauptpatents am Maschinenrahmen unveränderlich fest und nur in sich teilweise nachgiebig, sond-arn es ist nunmehr unter bestimmten Winkel und mit der Unterkante in genügendem Abstande über der Walze verstellbar befestigt, .wübei ferner auch der das Schutzglied trageivde Aufsatz am Maschinenrahmen verstellbär angeordnet ist.Protective device for the rollers of attritor mills and other machines. The object or invention is an improvement in the protective device for the rollers of attritor mills and other machines according to patent 3 ¢ 3368, especially for grinding and grinders, mixers and washers, and calendars, and the like consists in the type of attachment of the protective glielder to Aden side end pieces, to make them easily adjustable for the purpose of adapting to different heavy work goods and, on the other hand, the body size of the person operating the machine Worker. To that end, according to the invention, the protective member is no longer like in the subject of the main patent on the machine frame invariably fixed and only in itself partially yielding, but it is now under certain angles and adjustable with the lower edge at a sufficient distance above the roller, .Wübei also adjustable the protective member carrying attachment on the machine frame is arranged.

In der Zeichnung ist ' Abb. z ein Querschnitt .eines Teiles einer Reibmühle, die mit der Schutzvorrichtung gemäß der Erfindung ausgerüstet ist, Abb. 2 eine gleiche Ansicht von einem der Schutzglieder, Abb. 3 eine Draufsicht und Abb. q. eine Endansicht zu Abb. 2.In the drawing, Fig. Z is a cross-section of part of a Attritor equipped with the protection device according to the invention, Fig. Fig. 2 is a similar view of one of the protective members, Fig. 3 is a plan view, and Fig. q. an end view of Fig. 2.

Bei dem dargestellten Ausführungsbeispiele besitzt jede Schutzvorrichtung ein Schutzglied 7, welches längs und über der von ihm zu schützenden Walze 12 angeordnet ist. -Das Schutzglied 7, das zweckmäßig aus einer Aluminiumplatte besteht, aber auch aus anderen Stoffen hergestellt sein kann, ist mit Endzapfen 9 in - Endstüc cen 23 schwingbar gelagert, die mittels Stellschrauben 24 oder :in ariderer Weise senkrecht in Aufsätzen 25 des Maschinengestells i i geführt sind. An seinen Enden besitzt das Schutzglied 7 Lappen oder Anne 26, die mit Klenmnschrauben 27 ausgerüstet sind, deren Bolzen durch Schlitze 28 in den Endstücken 23 hindurchgehen. Durch Einstellung der Endstücke 23 kann der Abstand so verändert werden, daß der Durchgang irgendeiner gewünschten normalen .Dicke des Arbeitsguts zwischen der Unterkante 13 und der Walze 12 möglich ist, und durch Einstellung des Schutzgliedes um seine Zapfen 9 kann es jede erforderliche Neigung erhalten, um der Größe des Arbeiters oder sonstigen Zwecken angepaßt werden zu können. Nach der Einstellung erfolgt das Festklemmen mit Hilfe der Schrauben 27. Infolge dieser Anordnung ist das Schutzgliekl 7 während der Arbeit feststehend und seine Stellung kann so gewählt werden, daß es zwar den Durchgang einer verhältnismäßig großen Arbeitsgutdicke zwischen seiner Unterkante und der Walze 12 ,gestattet, aber den Arbeiter davor schützt, ,daß seine Hände zwischen der Unterkante des Schutzgliedes 7 und der Walze 12 so weit hindurchgreifen können, daß die Gefahr besteht, mit den Händen in den Einzug der Walzen 12 zu gelangen.In the illustrated embodiment, each protective device has a protective member 7 which is arranged along and above the roller 12 to be protected by it. The protective member 7, which is suitably made of an aluminum plate, but can also be made of other materials, is pivotably mounted with end pins 9 in - Endstüc cen 23, which are guided vertically by means of adjusting screws 24 or: in an ariderer way in attachments 25 of the machine frame ii are. At its ends, the protective member 7 has tabs or arms 26 which are equipped with set screws 27, the bolts of which pass through slots 28 in the end pieces 23. By adjusting the end pieces 23, the distance can be changed so that the passage of any desired normal .Dicke of the work material between the lower edge 13 and the roller 12 is possible, and by adjusting the protective member around its pin 9, it can be given any required inclination to be adapted to the size of the worker or other purposes. After the adjustment, it is clamped with the help of the screws 27. As a result of this arrangement, the protective link 7 is stationary during work and its position can be selected so that although it allows the passage of a relatively large work material thickness between its lower edge and the roller 12, but protects the worker from the fact that his hands can reach so far through between the lower edge of the protective member 7 and the roller 12 that there is a risk of the hands getting into the feeder of the rollers 12.
