Description

lYlaschine zum Schleifen, Polieren oder Aufrauhen von Leder mit Hilfe einer zwei verschiedene Bewegungen ausführenden Werkzeugtrommel Bei den bekannten Maschinen zum Schleifen, Polieren oder Aufrauhen von Leder mit Hilfe einer zwei verschiedene Bewegungen ausführenden Werkzeugtrommel erhält die an der Stirnfläche befindliche Arbeitsfläche eine kreisende Bewegung um eine Achse, die eine exzentrische Bewegung um eine parallel zu ihr verlaufende Achse ausführt.lYl machine for grinding, polishing or roughening leather with the help a tool drum executing two different movements Machines for sanding, polishing or buffing leather with the help of a two The tool drum that executes various movements receives the one on the face located work surface a circular motion around an axis that is eccentric Movement about an axis running parallel to it executes.

Da hier die beiden Bewegungen des Werkzeuges in gleichen Ebenen erfolgen, ist die Bildung von Rissen oder Kratzern in dem Arbeitsstück unvermeidlich.Since the two movements of the tool take place in the same planes, the formation of cracks or scratches in the workpiece is inevitable.

Der Zweck der Neuerung ist nun, den obenerwähnten Übelstand zn beseitigen, und zwar wird dies erfindungsgemäß dadurch erreicht, daß die Werkzeugtrommel mit am Umfang befindlicher Arbeitsfläche außer der Drehbewegung um ihre Längsachse noch eine kreisende Bewegung um eine senkrecht zu ihrer Längsachse stehende Achse ausführt.The purpose of the innovation is now to eliminate the above-mentioned deficiency, this is achieved according to the invention in that the tool drum with working surface located on the circumference apart from the rotary movement around its longitudinal axis executes a circular movement about an axis perpendicular to its longitudinal axis.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt: Abb. i ist eine Seitenansicht, teilweise im Schnitt, Abb. 2 eine Vorderansicht, Abb. 3 ein- teilweiser Grundriß.An exemplary embodiment of the invention is shown in the drawing: Fig. I is a side view, partly in section, Fig. 2 is a front view, Fig. 3 partial plan.

Die Werkzeugtrommel i, die auf der Umfläche mit einem Schleifmittel 2 (Schmirgelpapier o. dgl.) überzogen ist, lagert im Maschinengestell 3 und wird mittels einer Riemenscheibe q. in umlaufende Bewegung gesetzt. Das Arbeitsgut oder Werkstück 5 wird in bekannter Weise durch Anheben eines Gegendruckpölsters 7 mittels Fußhebels 6 oder einer angetriebenen Zuführungswalze gegen die Werkzeugtrommel i bewegt bzw. dieser zugeführt. Die beiden Lager ä der Werkzeugtrommel werden von je einem quer zur Trommelachse stehenden Zapfen 9 getragen, die in je einer exzentrischen Gestellmuffe ii gelagert sind, die ihrerseits von Kegelrädern io gedreht werden. Die Kegelräder io werden durch eine gemeinschaftliche, Kegelräder tragende Welle iz in Drehung versetzt, die von der Trommelwelle 15 aus durch Riemenscheiben 13, 1q. angetrieben wird.The tool drum i, which is coated on the peripheral surface with an abrasive 2 (emery paper or the like), is stored in the machine frame 3 and is moved by means of a belt pulley q. set in circular motion. The work item or workpiece 5 is moved in a known manner by lifting a counterpressure pad 7 by means of a foot lever 6 or a driven feed roller against the tool drum i or fed to it. The two bearings ä of the tool drum are each carried by a pin 9 which is transverse to the drum axis and which are each mounted in an eccentric frame sleeve ii, which in turn are rotated by bevel gears io. The bevel gears io are set in rotation by a common shaft iz carrying bevel gears, which is driven from the drum shaft 15 by pulleys 13, 1q. is driven.

Bei der Drehung der Werkzeugtrommel erhält die Welle i2 eine passend untersetzte Drehung, so daß eine kreisende Bewegung der Zapfen 9 entsteht und die Trommel daher außer ihrer Umlaufbewegung noch eine kreisende Bewegung in einer senkrecht zu den Zapfen 9 stehenden Ebene erhält. Sie reibt dabei auf dem Arbeitsgut entlang, wodurch der obenerwähnte Zweck erreicht wird.When the tool drum rotates, the shaft i2 receives a matching one stocky rotation, so that a circular movement of the pin 9 and the Therefore, in addition to its orbital motion, the drum also has a circular motion in a vertical direction to the pin 9 standing level receives. She rubs along on the work item, whereby the above-mentioned purpose is achieved.
