Description

Messerschleifmaschine mit zwei durch Federn gegeneinander gedrückten Schleifrollen. Die Erfindung betrifft eine Messer schleifmaschine mit in Umdrehung versetzten Schleifrollen, die federnd gegeneinander gedrückt werden. Gemäß der Erfindung ist mit den einfachsten Mitteln eine eine leichte Auswechslung erlaubende Befestigung der Anurückfedern erreicht, zugleich mit der Möglichkeit feiner Einstellung des Anpressungsdruckes und der Möglichkeit einfachster Auswechslung der Rollen.Knife sharpening machine with two springs pressed against each other Grinding rollers. The invention relates to a knife grinding machine with in rotation offset grinding rollers, which are resiliently pressed against each other. According to the invention with the simplest means is an attachment that allows easy replacement of the return springs achieved, at the same time with the possibility of fine adjustment of the Contact pressure and the possibility of easy replacement of the rollers.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung dargestellt. Abb. i ist eine Seitenansicht, Abb. a ein Grundriß.An embodiment of the subject matter of the invention is shown in the drawing shown. Fig. I is a side view, Fig. A is a plan view.

Die Wellen a der Rollen b greifen durch Langlöcher g in der Seitenwand f der Maschine hindurch und liegen in je einer zweckmäßig mit einer Ausfütterung c ausgestatteten lagerartigen Einbuchtung der Andrückfedern d. Diese Federn d sind dadurch leicht auswechselbar bzw. abnehmbar befestigt, daß sie einfach zwischen der Welle a und einer ihre Spannung zu verändern gestattenden Schraube lt und weiterhin der Fußplatte der Maschine eingespannt sind. Wie gezeichnet, kann das untere Ende der im wesentlichen S-förmig gebogenen Feder in einer flachen Tut der Grundplatte liegen. Eine solche Nut ist indessen keineswegs unentbehrlich.The shafts a of the rollers b reach through elongated holes g in the side wall f of the machine and each lie in a bearing-like indentation of the pressure springs d which is expediently equipped with a lining c. These springs d are easily exchangeable or detachable because they are simply clamped between the shaft a and a screw which allows their tension to be changed and the base plate of the machine continues to be clamped. As shown, the lower end of the essentially S-shaped bent spring can lie in a flat groove of the base plate. However, such a groove is by no means indispensable.

Der zwischen Schraube k und Welle a liegende Federbogen ist so groß gewählt, daß es unmöglich gemacht ist, die Rollen oder Bürsten mittels der Schrauben übermäßig gegeneinander zudrücken.The spring bow lying between screw k and shaft a is so large chosen that it is made impossible to remove the rollers or brushes by means of the screws pressing against each other excessively.

Soll eine Rolle b ausgewechselt werden, so wird die in Abb. 2 oben gezeichnete abnehmbare Seitenwand weggenommen und die entsprechende Feder d durch Zusammendrücken des Bogens zwischen Schraube h und Welle a von letzterer abgehoben und unter einer gewissen Drehung zur Seite (in Abb.2 nach. unten) vollständig aus ihren Einspannstellen herausgehoben. Nun ist die Welle a völlig entlastet. Die Bürste oder. Rolle b kann einfach abgezogen und dafür eine andere Rolle oder Bürste aufgesteckt werden, worauf die Feder d in umgekehrter Weise wieder angebracht wird: Für den Gebrauch der Maschine ist es natürlich von größter Wichtigkeit, daß der Anpressungsdruck der Rollen während des Betriebs fein eingestellt werden kann und daß gleichwohl die Auswechslung einer Rolle im Bedarfsfall mit wenigen Handgriffen und ohne den Gebrauch von Geräten, wie z. B. Schraubenziehern o. dgl.; möglich ist.If a roller b is to be replaced, the removable side wall shown above in Fig. 2 is removed and the corresponding spring d is lifted from the latter by compressing the arc between screw h and shaft a and turned to the side with a certain rotation (in Fig . below) lifted completely out of their clamping points. Now shaft a is completely relieved. The brush or. Roller b can simply be pulled off and another roller or brush can be attached, whereupon the spring d is reattached in the opposite way: For the use of the machine it is of course of the greatest importance that the contact pressure of the rollers can be finely adjusted during operation and that, however, the replacement of a role if necessary with a few simple steps and without the use of equipment such. B. screwdrivers or the like; is possible.

PATRNTANSPRÜCI3E: i. Messerschleifmaschine mit zwei durch Federn gegeneinander gedrückten Schleifrollen, gekennzeichnet durch zwei S-förmige Federn (d), die je ohne weitere Befestigung mit den Enden sich gegen eine der Schleifrollenwellen (a) und die Grundplatte der Maschine und mit dem an letzterer anliegenden Federbogen gegen eine zur Änderung der Federspannung dienende Stellschraube (h) stützen. PATENT CLAIMS: i. Knife grinding machine with two springs against each other pressed grinding rollers, characterized by two S-shaped springs (d), each without further fastening with the ends against one of the grinding roller shafts (a) and the base plate of the machine and with the spring bow attached to the latter Support against an adjusting screw (h) used to change the spring tension. 2. Maschine nach Anspruch i, dadurch gekennzeichnet, daß der an der Welle (a) anliegende Federbogen größer ausgebildet ist als der an der Grundplatte und Stellschraube anliegende, um ein übermäßiges Festdrücken der Rollen zu verhindern.2. Machine according to claim i, characterized in that the one resting on the shaft (a) The spring bow is larger than the one resting on the base plate and the adjusting screw, to prevent excessive pressing of the rollers.
