Description

Die Erfindung betrifft ein Fertigungssystem der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a manufacturing system in Preamble of claim 1 mentioned type.

Bekannte Fertigungssysteme der betreffenden Art zur Herstellung von Verschlußkappen für Behälter, z.B. Gläser für Lebensmittel, weisen in einer Reihe angeordnete unterschiedliche Werkzeugstationen auf, die über eine Transporteinrichtung in einer Reihe verbunden sind und die nacheinander Einzelschritte eines Fertigungsverfahrens zur Fertigung der Werkstücke ausführen. In einer Reihe findet sich z.B. zunächst ein Stanzwerkzeug, das einen Deckelrohling aus Blech ausstanzt und gleichzeitig tiefzieht. Nach Abschluß dieses Fertigungsschrittes transportiert die Transporteinrichtung den so geformten Rohling zu einer zweiten Werkzeugstation, in der vorgerollt wird. Danach gelangt der vorgerollte Rohling in eine nachfolgende Werkzeugstation, in der das Nachverformen erfolgt und dann in eine weitere Werkzeugstation, in der das Einbringen des Compounds erfolgt. Schließlich wird in einer letzten Werkzeugstation der Button hergestellt, eine Wölbung im zentralen Bereich des Deckels.Known manufacturing systems of the type concerned for the manufacture of caps for containers, e.g. Food jars, arranged in a row different tool stations that over a transport device are connected in a row and the successive individual steps of a manufacturing process to manufacture the workpieces. In one row is e.g. first a punching tool, which punches out a blank cover from sheet metal and deep drawing at the same time. After completing this manufacturing step transports the transport device the blank thus shaped to a second tool station, in which is pre-rolled. Then the pre-rolled arrives Blank in a subsequent tool station, in which the post-forming takes place and then into another Tool station in which the introduction of the compound he follows. Finally, in a final tool station made the button, a bulge in the central area of the lid.

Ein Nachteil dieses bekannten Fertigungssystems besteht darin, daß alle Werkzeugstationen zusammen eine Einheit bilden und von einer gemeinsamen Antriebsvorrichtung angetrieben und einer gemeinsamen Steuervorrichtung gesteuert sind. Da jede Werkzeugstation einem Verschleiß unterliegt und außerdem Ausfälle in jeder Werkzeugstation vorkommen können, führt ein Fehler oder ein Ausfall in einer Werkzeugstation der in Reihe angeordneten Werkzeugstationen zum Stillstand aller Werkzeugstationen in der Reihe. Dadurch wird der Fertigungsvorgang dieser Reihe so lange unterbrochen, bis der Fehler behoben ist, wodurch sich Fertigungsverluste ergeben, die beträchtlich sein können.A disadvantage of this known manufacturing system is that all tool stations together have one Form unit and from a common drive device driven and a common control device are controlled. Because every tool station is one Wear is subject to and also failures in everyone Tool station can lead to an error or a failure in a tool station arranged in series Tool stations to stop all tool stations in line. This will make the manufacturing process interrupted this row until the bug is fixed, causing manufacturing losses result that can be considerable.

Der Erfindung liegt die Aufgabe zugrunde, ein Fertigungssystem der betreffenden Art zu schaffen, bei dem Fertigungsausfälle durch Fehler oder Ausfälle einer Werkzeugstation einer Reihe verringert ist.The invention has for its object a manufacturing system of the kind concerned, in which Manufacturing downtime due to failure or failure of one Tool station of a row is reduced.

Die der Erfindung zugrundeliegende Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebene Lehre gelöst.The object underlying the invention will by the specified in the characterizing part of claim 1 Doctrine solved.

Der Grundgedanke der erfindungsgemäßen Lehre besteht darin, die Werkzeuge der Werkzeugstationen austauschbar und steckbar an einer gemeinsamen Basis anzuordnen. Somit ist es möglich, bei Ausfall eines Werkzeugs einer Werkzeugstation dieses während eines kurzen Stillsetzens des gesamten Fertigungssystems aus seiner Steckverbindung zu lösen und von der gemeinsamen Basis abzunehmen und durch ein neues, intaktes Werkzeug zu ersetzen. Nach wenigen Handgriffen kann also das gesamte Fertigungssystem weiterarbeiten, so daß praktisch keine Fertigungsausfälle stattfinden.The basic idea of the teaching according to the invention is in that the tools of the tool stations are interchangeable and pluggable on a common base. It is therefore possible in the event of a tool failure a tool station this during a short Shutting down the entire manufacturing system from its Disconnect connector and from the common base remove and with a new, intact tool replace. After a few simple steps, the whole thing can be done Manufacturing system continue to work, so practical no production downtimes take place.

Gemäß einem weiteren Merkmal der Erfindung sind die einzelnen Werkzeugstationen jeweils autark ausgebildet, sie sind dazu mit eigenen Antriebs- und Steuermitteln versehen. Das bedeutet, daß bei einem Ausfall in einer Werkzeugstation alle ausfallträchtigen Teile einer Werkzeugstation unabhängig von anderen Werkzeugstationen ausgetauscht werden können.According to a further feature of the invention the individual tool stations are each self-sufficient, for this they have their own drive and control means Mistake. That means that in the event of a failure all fail-safe parts in one tool station one tool station independent of other tool stations can be exchanged.

Natürlich müssen die einzelnen Werkzeugstationen im Takt miteinander arbeiten. Aus diesem Grund weist gemäß einem weiteren Merkmal der Erfindung jedes Werkzeug Verbindungsmittel auf, die die Antriebs- und Steuermittel im eingesteckten Zustand der Werkzeuge mit einer allen Werkzeugen gemeinsamen Takteinrichtung verbinden.Of course, the individual tool stations work together in time. Because of this, points according to a further feature of the invention, each tool Connection means on which the drive and control means in the inserted state of the tools connect a clock device common to all tools.

Gemäß einer Weiterbildung der Erfindung ist die Basis als Arbeitsplatte ausgebildet. Diese hält die einzelnen Werkzeugstationen in der gewünschten räumlichen Zuordnung, in der die Werkstücke mit jedem Takt von einer Werkzeugstation zur nächsten weiterbefördert werden. Dabei ist es zweckmäßig, daß die Arbeitsplatte die Zuführeinrichtung zur Zuführung der Werkstücke zu den Werkzeugen aufweist. Auch ist es zweckmäßig, wenn die Arbeitsplatte Justier- und/oder Spannmittel für die Werkzeuge aufweist.According to a development of the invention Base designed as a worktop. This holds the individual tool stations in the desired spatial Assignment in which the workpieces with each cycle conveyed from one tool station to the next become. It is useful that the worktop the feed device for feeding the workpieces the tools. It is also useful if the worktop adjustment and / or clamping device for the Has tools.
