Abstract

1. Device for making small plates consisting of reverse rollers or roller segments, which are actuated by means of electromechanical, pneumatic or hydraulic driving elements and have a working gap for transportation and for embossing a blank supplied to the device, characterised in that the working gap (5) between the rollers (1, 2) or roller segments is adapted to transform a coin supplied as a blank into an oval shape, and in addition an embossing element (11) is disposed on the circumference of at least one roller (2) or rolling element for the application of a pattern.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Herstellung von Plaketten, bestehend aus gegenläufigen Walzen bzw. Walzensegmenten, die über elektromechanische, pneumatische bzw. hydraulische Antriebsorgane betätigt werden und einen Bearbeitungsspalt zum Transport sowie zur Prägung eines zugeführten Rohlings aufweisen.The invention relates to a device for producing badges, consisting of counter-rotating rollers or roller segments, which are actuated via electromechanical, pneumatic or hydraulic drive elements and have a machining gap for transporting and for embossing a supplied blank.

Vorrichtungen dieser Art zur Prägung bzw. Signierung sind u. a. nach US-A-1 329 941 bekannt. Hierbei wird ein in der vorgegebenen Form vorliegendes Teil entsprechend signiert. Diese als reine Prägemaschinen anzusehenden Anordnungen sind für eine Materialumformung nicht einsetzbar. Es besteht somit auch der Mangel, daß eine Bearbeitung eines bereits mit einer Prägung versehenen zu markierenden Materials nicht durchführbar ist.Devices of this type for embossing or signing are u. a. known from US-A-1 329 941. In this case, a part in the specified form is signed accordingly. These arrangements, which are to be regarded as pure embossing machines, cannot be used for material forming. There is therefore also a defect that it is not possible to process a material that is already to be marked with an embossing.

Die Aufgabe der Erfindung ist es, eine Vorrichtung der gattungsgemäßen Art zum Walzen und individuellen Prägen von als Rohlinge eingegebenen Münzen zu schaffen um ovale Plaketten herzustellen, die entsprechend auf den Aufstellungsort hinweisen bzw. voreingestellte Motive aufweisen.The object of the invention is to create a device of the generic type for rolling and individual embossing of coins entered as blanks in order to produce oval badges which accordingly indicate the installation site or have preset motifs.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, daß der Bearbeitungsspalt zwischen den Walzen bzw. Walzensegmenten zur Materialumformung einer als Rohling zugeführten Münze in eine ovale Form bemessen und ein Prägeelement zusätzlich am Umfang mindestens einer Walze bzw. eines Walzenelementes zum Aufbringen eines Abbildes angeordnet ist.This object is achieved according to the invention in that the machining gap between the rollers or roller segments for material shaping of a coin fed as a blank into an oval shape is dimensioned and an embossing element is additionally arranged on the circumference of at least one roller or one roller element for applying an image.

Hierdurch wird es erst möglich, als Rohlinge zugeführte Münzen mit einer anderen vorgegebenen Prägung bzw. Kennzeichnung zu versehen.This only makes it possible to provide coins supplied as blanks with a different predetermined embossing or identification.

In Ausgestaltung der Erfindung und wahlweiser Erstellung unterschiedlicher Prägung wird vorgeschlagen, daß das Prägeelement als verschiebbar angeordnete Schiene mit unterschiedlichen Motiven ausgebildet ist und jedes Motiv wahlweise durch Querverschiebung, bezogen auf die Abrollrichtung der Walze bzw. des Walzensegmentes, für eine Prägung einstellbar ist.In an embodiment of the invention and optional creation of different embossing, it is proposed that the embossing element is designed as a displaceably arranged rail with different motifs and that each motif can be set for embossing by transverse displacement, based on the rolling direction of the roller or the roller segment.

In der Zeichnung sind Ausführungsbeispiels der Erfindung schematisch dargestellt. Es zeigen:

  • Fig. 1 eine Draufsicht auf eine Vorrichtung mit abgenommener Ständerplatte,
  • Fig. 2 einen Schnitt gemäß Linie 11-11 der Fig. 1,
  • Fig. 3 einen Schnitt wie Fig. 2 mit einstellbaren unterschiedlichen Prägeelementen als verstellbare Schiene.
Exemplary embodiments of the invention are shown schematically in the drawing. Show it:
  • 1 is a plan view of a device with the stand plate removed,
  • 2 shows a section along line 11-11 of FIG. 1,
  • Fig. 3 shows a section like Fig. 2 with adjustable different embossing elements as an adjustable rail.

Bei der dargestellten Vorrichtung sind zwei Walzen 1, 2 mit einem Ständer 3 parallel über Achsen 4 drehbar angeordnet. Hierbei sind die Mantelflächen der Walzen 1, 2 einander zugewandt und bilden einen Bearbeitungsspalt 5 zur Aufnahme einer zugeführten Münze als Rohling. Die zugeführte Münze wird gegebenenfalls gehalten, um einen Einziehvorgang in den Bearbeitungsspalt 5 zwischen die Walzen 1, 2 zu gewährleistenIn the device shown, two rollers 1, 2 with a stand 3 are arranged rotatably in parallel via axes 4. Here, the lateral surfaces of the rollers 1, 2 face each other and form a processing gap 5 for receiving a coin as a blank. The supplied coin is optionally held in order to ensure a drawing process into the processing gap 5 between the rollers 1, 2

Die Walzen 1, 2 werden über integrierte Antriebsarme 6, 7 gegenläufig angetrieben, indem die Antriebsarme 6, über Antriebshebel 8, 9 gelenkig verbunden sind und über einen Hydraulikzylinder 10 in bekannter Weise gekoppelt sind. Der dadurch auf die zugeführte Münze einwirkende Walzvorgang formt die runde Münze in eine ovale Plakette um.The rollers 1, 2 are driven in opposite directions via integrated drive arms 6, 7 in that the drive arms 6 are articulated via drive levers 8, 9 and are coupled in a known manner via a hydraulic cylinder 10. The rolling process that acts on the supplied coin transforms the round coin into an oval badge.

Da die Walze 2 an ihrem Umfang ein Prägeelement 11 mit einem Motiv aufweist, wird das Prägeelement 11 während des Walzvorganges auf die entstehende Plakette aufgebracht. Hierdurch ist es möglich, durch einen Benutzer nach Einwurf einer Münze als Rohling sowie Durchführung des Walzvorganges in der Vorrichtung beispielsweise eine individuell gefertigte Andenkenplakette herzustellen.Since the roller 2 has an embossing element 11 with a motif on its circumference, the embossing element 11 is applied to the resulting badge during the rolling process. This makes it possible, for example, for a user to produce an individually manufactured souvenir plaque after inserting a coin as a blank and performing the rolling process in the device.

Gemäß Fig. 3 sind unterschiedliche Motive für ein Prägeelement 11' auf einer Schiene 12 angeordnet. Durch eine wahlweise Verschiebung der Schiene 12 über einen zugeordneten Verschiebezylinder 13 ist es möglich, daß ein ausgewähltes Motiv als Prägeelement 11' einstellbar ist. Hierzu wird eine Querverschiebung der Schiene 12 bezogen auf die Abrollvorrichtung der Walzen 1, 2 vorgenommen.3, different motifs for an embossing element 11 'are arranged on a rail 12. Through an optional displacement of the rail 12 via an associated displacement cylinder 13, it is possible for a selected motif to be adjustable as the embossing element 11 '. For this purpose, the rail 12 is moved transversely with respect to the rolling device of the rollers 1, 2.
