PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft eine Knopflochschneidmaschine für Schuhschäfte. Ähnliche Maschinen sind bereits bekannt, doch besitzen diese keinen selbsttätigen Vorschub; dieser aber bildet den Gegenstand der vorliegenden Erfindung.The present invention relates to a buttonhole cutting machine for shoe uppers. Similar Machines are already known, but they do not have an automatic feed; but this forms the subject of the present invention.
In der Zeichnung stelltIn the drawing represents
Fig. ι eine Seitenansicht undFig. Ι a side view and
Fig. 2 einen Schnitt in Richtung a-b der ίο Fig. ι dar.Fig. 2 shows a section in the direction from the ίο Fig. Ι.
Beim Knopflocheinschneiden wird zunächst der Tisch r, welcher durch eine im Innern der Büchse s liegende Feder hochgehalten wird, durch Fußtritt t nach unten gezogen, damit der Schaft zwischen die Transporträder q und u gebracht werden kann, die nach Freigeben des Fußtritts t den Schaft festhalten.When cutting the buttonhole, the table r, which is held up by a spring located inside the sleeve s , is first pulled down by a kick t so that the shaft can be brought between the transport wheels q and u , which hold the shaft in place after the kick t is released .
Der Stempel k sitzt an einer Stange h, die durch Excenterscheibe f und Rolle g nach oben gezogen, durch Feder i dagegen nach unten gedrückt wird und hierdurch das Knopfloch einschneidet.The punch k sits on a rod h, which is pulled up by eccentric disk f and roller g , but is pressed down by spring i and thereby cuts the buttonhole.
Der Antrieb erfolgt durch die Welle c, Räder d und e. Während des Hochganges des Stempels tritt nun der Vorschub in Tätigkeit, indem die Hubscheibe / vermittels der Stange m zunächst die die Sperrklinke ρ tragende, auf der Achse lose drehbar angeordnete Doppelscheibe ο dreht. Die Sperrklinke ρ dreht ein Sperrad η, das mit dem Transportrad q auf derselben Welle sitzt.It is driven by shaft c, wheels d and e. During the upward movement of the ram, the feed now comes into operation, in that the lifting disk / by means of the rod m first rotates the double disk ο, which bears the pawl ρ and is loosely rotatably arranged on the axis. The pawl ρ rotates a ratchet wheel η, which sits with the transport wheel q on the same shaft.
Die Vorschublänge kann auf der Hubscheibe / beliebig eingestellt werden.The feed length can be set as desired on the lifting disc /.
