KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft ein Schutzgehäuse mit aufklappbarer Wand, an der drehbar und radial verschiebbar ein Schutzschild angebracht ist, für Kreismesser, insbesondere für solche von Zuschneidemaschinen. Die Neuerung besteht darin, daß der Schutzschild in einem durch ein Zahngetriebe drehbaren Lager mittels Zahnstangentrieb verschiebbar ist.The invention relates to a protective housing with a hinged wall on which can be rotated and A protective shield is attached to be radially displaceable, for circular knives, in particular for those of cutting machines. The innovation is that the protective shield in one is displaceable by means of a rack and pinion gear rotatable bearing by a toothed gear.
Durch diese Einrichtung soll den bekanntenThrough this facility, the well-known
ίο Schutzvorrichtungen gegenüber ein schnelleres und genaueres Einstellen und Anpassen des Schutzschildes an das Kreismesser ermöglicht werden.ίο guards against a faster and allows more precise setting and adaptation of the protective shield to the circular knife will.
In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt, und zwar zeigen: Fig. 1 eine Vorderansicht mit Weglassung der Handgriffe für die Getriebe, Fig. 2 eine teilweise Seitenansicht einer Zuschneidemaschine mit dem Schutzgehäuse, Fig. 3 das Schutzgehäuse in größerem Maßstab.In the drawing, the subject matter of the invention is shown in an exemplary embodiment, namely show: FIG. 1 a front view with the omission of the handles for the transmission, FIG. 2 a partial side view of a cutting machine with the protective housing, 3 shows the protective housing on a larger scale.
Das Messer c der Zuschneidemaschine wird von einem Gehäuse teilweise eingeschlossen, welches aus einer mit dem Messerhalter fest verbundenen Wand k und einer an diese angelenkten Wand b besteht. Beide Wände werden durch eine Schraube m, deren Kopf teilweise beseitigt ist, damit er nach Teildrehung durch die Öffnung η hindurchtreten kann, zusammengehalten. Innerhalb des Gehäuses ist an der Wand b ein Lager α auf der Messerachse schwingend angeordnet. Mittels eines an der Gehäusewand b befindlichen Zahntriebes d, das in einen gezahnten Rand des Lagers α eingreift, kann dieses um seine Achse gedreht werden. In dem Lager α ruht schlittenartig der Arm β des Schutzschildes f, der den freiliegenden Teil des Kreismessers c, soweit dies nicht in den zu durchschneidenden Stoff eindringt, abdecken und um ein geringes überragen soll, damit Handverletzungen des bedienenden Arbeiters vermieden werden. Das Verstellen des Armes e geschieht durch das in die gezahnte Aussparung des Armes eingreifende Zahnrad g, welches im Lager a angeordnet ist und dessen Achse in einem Schlitz h der Gehäusewand b Spielraum hat. Die Achsen der Zahntriebe e und g ragen aus der Gehäusewand b heraus und sind durch aufgesetzte Schlüssel i von außen drehbar. Zum Schleifen des Kreismessers wird die Schraube m gelöst und die Gehäusewand b nebst dem daran befestigten Lager zurückgeklappt. The knife c of the cutting machine is partially enclosed by a housing which consists of a wall k firmly connected to the knife holder and a wall b hinged to it. Both walls are held together by a screw m, the head of which has been partially removed so that it can pass through the opening η after partial rotation. Within the housing, a bearing α is arranged swinging on the knife axis on the wall b. By means of a toothed drive d located on the housing wall b , which engages in a toothed edge of the bearing α , this can be rotated about its axis. The arm β of the protective shield f rests like a slide in the bearing α and covers the exposed part of the circular knife c, unless it penetrates into the material to be cut, and is intended to protrude slightly so that hand injuries to the operating worker are avoided. The adjustment of the arm e is done by the gear wheel g engaging in the toothed recess of the arm, which is arranged in the bearing a and the axis of which has clearance in a slot h in the housing wall b. The axes of the gear drives e and g protrude from the housing wall b and can be rotated from the outside by means of an attached key i. To grind the circular knife, the screw m is loosened and the housing wall b and the bearing attached to it are folded back.
