Description
Zur Geradführung von Filzen, Sieben u. dgl. an Pappen-, Papier- und ähnlichen Maschinen hat man bisher ein Ende der Leitwalze durch Handbetrieb mittels einer Schraubenspindel verschoben, wodurch der auf die Seite gelaufene Filz in die richtige Mittelstellung zurückgebracht wird. Man hat auch zur selbsttätigen Geradführung in einem Sohwingrahmen gelagerte Leitwalzen benutzt, die unter dem Einfluß des aus der Mittellage verlaufenden Filzes um eine senkrechte Achse schwingen und dadurch das Sieb in die Mitfellage zurückführen.For straight guidance of felts, sieves and the like on cardboard, paper and the like Machines have so far moved one end of the guide roller by manual operation by means of a screw spindle, whereby the The felt that has run on the side is returned to the correct center position. One has guide rollers mounted in a swinging frame are also used for automatic straight-line guidance, under the influence of the felt running from the middle layer around a vertical one Swing the axis and thereby bring the sieve back into the middle layer.
Im Gegensatz zu diesen Einrichtungen liegt die gemäß der Erfindung zur Geradführung benutzte Leitwalze in einem um eine waagerechte Achse schwenkbaren Rahmen, der außerdem um eine senkrechte Achse drehbar ist.In contrast to these bodies lies the guide roller used according to the invention for straight guidance in a around a horizontal Axis swiveling frame, which can also be rotated around a vertical axis is.
Die Erfindung ist in der Zeichnung beispielsweise dargestellt, und es zeigtThe invention is illustrated in the drawing, for example, and it shows
Abb. ι die Längsansicht des Apparates, zur Hälfte geschnitten,Fig. Ι the longitudinal view of the apparatus, cut in half,
Abb. 2 die Seitenansicht, ebenfalls im Schnitt.Fig. 2 the side view, also in section.
Die Anordnung und Arbeitsweise der Regeleinrichtung nach der Erfindung ist folgende: The arrangement and mode of operation of the control device according to the invention is as follows:
Die Leitwalze α hängt in dem Gestell b, das in 'der Mitte durch zwei waagerechte Zapfen c und eine senkrechte drehbare Führung g getragen wird. Neben der Leitwalzea ist an einer Seite an 'der Schiene i ein Rahmen / angeordnet, der an Führungszapfen h hängt und durch Exzenterübertragung o. dgl. in hin und her gehende Bewegung gesetzt wird. Der Rahmen f trägt Nocken e. Bei Mittellauf des Filzes ist die Leitwalzea im Gleichgewicht; infolgedessen liegt das Walzenende d zwischen der Laufbahn der hin und her gehenden Nocken, so daß keiner der beiden Nocken e es erfaßt, solange die Mittelstellung besteht. Beim Verlaufen des Filzes kippt die Leitwalze α durch die ungleiche Belastung aus der waagerechten in eine geneigte Lage. Das eine der dadurch gehobenen bzw. gesenkten Walzenenden d wird von einem der beiden Nokken e erfaßt und die Leitwalze α um die Zylinderführung |· gedreht. Die beiden Schrauben k sind Anschlagschraulben, die verhindem, daß sich das Walzenende d durch unvorhergesehene: Umstände drehen kann.The guide roller α hangs in the frame b, which is carried in the middle by two horizontal pins c and a vertical rotatable guide g . In addition to the guide roller a, a frame / is arranged on one side of the rail i , which hangs on the guide pin h and is set in reciprocating motion by eccentric transmission or the like. The frame f carries cams e. In the middle of the felt, the guide roller a is in equilibrium; As a result, the end of the roll d lies between the raceway of the reciprocating cams, so that neither of the two cams e detects it as long as the central position exists. When the felt runs, the guide roller α tilts from the horizontal to an inclined position due to the unequal load. One of the roller ends d raised or lowered as a result is grasped by one of the two cams e and the guide roller α is rotated about the cylinder guide. The two screws k are stop screws that prevent the roll end d from turning due to unforeseen circumstances.
