Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Den Gegenstand der Erfindung bildet eine ■ Vorrichtung zum Schleifen der Kreis- oder Tellermesser an Papierschneidemaschinen während des Betriebes. Gegenüber bekannten Vorrichtungen dieser Art besitzt die neue Schleifvorrichtung den Vorteil, daß die Kreismesser der Papierschneidemaschine unterhalb oder oberhalb der Papierbahn geschliffen werden können, während letztere durch die ίο Maschine läuft, ohne daß die Papierbahn durch einen Riemen oder ein Vorgelege in ihrem Laufe gehemmt wird.The object of the invention forms a ■ device for grinding the circular or Disc knives on paper cutting machines during operation. Compared to known Devices of this type, the new grinding device has the advantage that the circular knife the paper cutting machine can be sanded below or above the paper web, while the latter through the ίο The machine runs without the paper web being in its course is inhibited.

Zu diesem Zwecke besteht die VorrichtungThe device exists for this purpose

aus einem auf dem Gestell der Papierschneidemaschine zu befestigenden Rahmen, der zur Aufnahme und Führung eines auf letzterem mittels Spindel und Kurbel verschiebbaren Drehsupports dient, welcher die durch einen endlosen Seiltrieb von der Maschine aus in Umdrehung versetzte Schleifscheibe trägt.from a frame to be attached to the frame of the paper cutting machine, which is used for Receipt and guidance of one which can be displaced on the latter by means of a spindle and crank Rotary supports are used, which are controlled by an endless cable drive from the machine in rotation offset grinding wheel carries.

Fig. 3 zeigt den Support mit Schleifscheibe und Führungsrollen in Seitenansicht.Fig. 3 shows the support with grinding wheel and guide rollers in side view.

Auf dem die drehbaren Kreismesser a tragenden Rahmen b der Maschine ist mittels der Schrauben c, c der Rahmen d einstellbar befestigt, welcher eine in den Lagern e, e mittels Handkurbel / drehbare Leitspindel g trägt. Auf letzterer wird mittels der Mutter h der Support i geführt, der auf dem schwalbenschwanzförmigen Rahmen d verschiebbar ist. Auf dem Support ist um den Schraubbolzen k einstellbar eine Platte / befestigt, welche in zwei Auslegern m, m die Schleifscheibe η trägt, auf deren Achse die Seilrolle 0 sitzt. Auf der Platte / sind noch zwei Seilführungsrollen ρ, ρ gelagert. An den Enden des Rahmens d befinden sich ebenfalls zwei Seilrollen q, r, von welchen die eine, q, mittels des Kegelradgetriebes s und der Riemenscheibe t von der Maschine aus gedreht werden kann. Über die Scheiben 0, p, q, r ist das endlose Seil u geführt.On the frame b of the machine carrying the rotatable circular knives a , the frame d is adjustably fastened by means of the screws c, c and carries a lead screw g which can be rotated in the bearings e, e by means of a hand crank. The support i , which can be moved on the dovetail-shaped frame d, is guided on the latter by means of the nut h. On the support, a plate / is adjustable around the screw bolt k , which carries the grinding wheel η in two arms m, m , on the axis of which the pulley 0 is seated. Two rope guide rollers ρ, ρ are supported on the plate /. At the ends of the frame d there are also two pulleys q, r, one of which, q, can be rotated from the machine by means of the bevel gear s and the pulley t. The endless rope u is guided over the disks 0, p, q, r.

Durch Drehung der Handkurbel f kann die Schleifscheibe gegen die senkrechte Schneidfläche eines Kreismessers α gedrückt werden, um diese zu schleifen. Durch geeignete Einstellung der Platte I in eine der Pfeilrichtungen kann auch die schräge Mantelfläche des Kreismessers geschliffen werden.By turning the hand crank f , the grinding wheel can be pressed against the vertical cutting surface of a circular knife α in order to grind it. By suitably setting the plate I in one of the directions of the arrow, the inclined lateral surface of the circular knife can also be ground.
