Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Wechseln von Modellplatten in Formmaschinen, wobei von einer Hubstation die Modellplatte von einem, in den Bereich der Formmaschine reichenden Drehttisch oder Drehkreuz zu einem Modellplattenwagen einer zubringeinrichtung zugebracht wird.The present invention relates to a device for changing model plates in molding machines, the model plate being fed from a lifting station from a turntable or turnstile reaching into the area of the molding machine to a model plate carriage of a feeding device.

Zum Wechseln von Modellplatten sind eine Reihe von Vorrichtungen bekannt, bei welchen die Modellplatten z.B. durch eine Querbewegung von einer Lagerstation in die Formmaschine verschoben werden. Andere Einrichtungen basieren auf dem Prinzip des Drehtisches oder Drehkreuzes, wobei aus einer Magazinstation ein Modellträger entnommen wird und während eines Taktunterbruches der Formmaschine gegen einen sich in der Formmaschine befindlichen Modellträger ausgetauscht wird.A number of devices are known for changing model plates, in which the model plates e.g. are moved by a transverse movement from a storage station into the molding machine. Other devices are based on the principle of the turntable or turnstile, a model carrier being removed from a magazine station and exchanged for a model carrier located in the molding machine during a cycle interruption of the molding machine.

Im weiteren sind Einrichtungen bekannt, bei denen zwischen dem Drehtisch und der Modellplattenlagerstation eine Zwischeneinrichtung verwendet wird, mittels welcher die Modellplatten vom Drehtisch übernommen und in die Lagerstation bewegt werden.Furthermore, devices are known in which an intermediate device is used between the turntable and the model plate storage station, by means of which the model plates are taken over from the turntable and moved into the storage station.

Eine Vorrichtung der eingangs genannten Gattung ist aus der DE-A-30 22 651 bekannt, welche einen an einem Gestell befestigten Hubzylinder aufweist an dessen Kolbenstange ein Hubrahmen mit vertikalen Trennzylindern angeordnet ist und im Modellplattenträger in einem vorzugsweise orthogonalen Raster je Teilmodellplatte vorzugsweise je vier Durchbrüche angeordnet sind, wobei Anzahl und Rastermass der Trennzylinder mit der Anordnung der Durchbrüche übereinstimmen.A device of the type mentioned is known from DE-A-30 22 651, which has a lifting cylinder attached to a frame, on the piston rod of which a lifting frame with vertical separating cylinders is arranged and in the model plate carrier in a preferably orthogonal grid for each partial model plate, preferably four openings are arranged, the number and pitch of the separating cylinders matching the arrangement of the openings.

Der Nachteil dieser Einrichtung besteht darin, dass für einen Modellplattenaustausch eine Mehrzahl von Einrichtungen kombiniert eingesetzt werden müssen, die sehr kostenintensiv sind. Zudem können Verunreinigungen auftreten, die die genaue Positionierung der Modellplatten nicht mehr gewährleisten.The disadvantage of this device is that a plurality of devices that are very cost-intensive must be used in combination for a model plate exchange. In addition, contamination can occur that no longer guarantee the exact positioning of the model plates.

Es ist Aufgabe der Erfindung die genannten Nachteile zu eliminieren und eine Vorrichtung zu schaffen, mittels welcher vorbereitete Modellplatten ohne Taktunterbruch der Formmaschine gewechselt werden können, und eine Positionierung von Modellplattenteilen ausserhalb des Bereiches der Formmaschine möglich ist.It is an object of the invention to eliminate the disadvantages mentioned and to provide a device by means of which prepared model plates can be changed without interrupting the cycle of the molding machine, and positioning of model plate parts outside the area of the molding machine is possible.

Diese Aufgabe wird durch die Lehre des Anspruches 1 gelöst.This object is achieved by the teaching of claim 1.

Die Erfindung wird anhand der Figur näher erläutert.The invention is illustrated by the figure.

Sie zeigt in schematischer Darstellung einen Drehtisch 1, der mit einer Position 2 die Lage der Modellplatte in der Formmaschine angibt. Mit 3 ist die Lage der Modellplatte ausserhalb der Formmaschine dargestellt, welche mit der Lage einer Hubstation übereinstimmt. Die Hubstation weist einen Hubtisch auf, der über eine Zylinderanordnung in vertikaler Richtung (7) bewegt werden kann.It shows a schematic representation of a rotary table 1, which indicates the position of the model plate in the molding machine with a position 2. 3 shows the position of the model plate outside the molding machine, which corresponds to the position of a lifting station. The lifting station has a lifting table which can be moved in the vertical direction (7) via a cylinder arrangement.

Die Bewegung kann sowohl pneumatisch, hydraulisch wie elektro-mechanisch erfolgen. An der Oberseite des Hubtisches sind vorzugsweise nicht dargestellte antreibbare Rollen angeordnet, die in ihrer Dimensionierung den Modellplatten angepasst sind. Die Hubstation hat eine untere Lage, in welcher die Vertikalachse 7 der Hubstation den Schwenkkreis 4 des Drehtisches 1 schneidet. Die obere Endlage der Hubstation befindet sich im Bereich einer Zubringeinrichtung 6 für die Modellplatten. Durch die Vertikalachse 7 der Hubstation verläuft in horizontaler Richtung die Achse 5 der Zubringeinrichtung 6.The movement can be pneumatic, hydraulic or electro-mechanical. At the top of the lifting table there are preferably drivable rollers, not shown, whose dimensions are adapted to the model plates. The lifting station has a lower position in which the vertical axis 7 of the lifting station intersects the swivel circle 4 of the turntable 1. The upper end position of the lifting station is in the area of a feed device 6 for the model plates. The axis 5 of the feed device 6 runs in the horizontal direction through the vertical axis 7 of the lifting station.

Die Zubringeinrichtung 6 besteht im wesentlichen aus mindestens zwei mit nicht dargestellten Rollen versehenen Modellplattenwagen. Diese Rollen dienen zur Aufnahme der Modellplatten und sind angetrieben. Zur Bewegung dieser Modellplattenwagen in den Bereich des Hubtisches sind an der Unterseite der Modellplattenwagen Verschiebevorrichtungen, beispielsweise Schubkolbenantriebe vorgesehen.The feed device 6 essentially consists of at least two model plate carriages provided with rollers, not shown. These rollers are used to hold the model plates and are driven. In order to move these model plate carriages into the area of the lifting table, displacement devices, for example thrust piston drives, are provided on the underside of the model plate carriages.

Der Betriebsablauf der Vorrichtung ist wie folgt:

  • Während oder nach der Herstellung einer Form wird die in der unteren Lage der Hubstation sich befindende Modellplatte von der Hubstation übernommen und in die obere Lage in die Höhe der Achse 5 der Zubringeinrichtung 6 verschoben. Gleichzeitig werden die beiden Modellwagen mittels der Schubkolbenantriebe in den Bereich der oberen Hubstation gebracht.
The operation of the device is as follows:
  • During or after the production of a mold, the model plate located in the lower position of the lifting station is taken over by the lifting station and moved into the upper position in the height of the axis 5 of the feed device 6. At the same time, the two model cars are brought into the area of the upper lifting station by means of the push piston drives.

In dieser Lage wird die Modellplatte von den im Hubtisch angeordneten Rollen auf den bereitstehenden leeren Modellwagen bewegt. Gleichzeitig rollt über die angetriebenen Rollen des anderen Modellwagens eine bereitgehaltene Modellplatte auf die Rollen des Hubtisches. Anschliessend fahren beide Modellwagen in ihre Ausgangslagen zurück, und der Hubtisch wird mit übernommenen Modellplatten in das Einschwenkniveau des Drehtisches 1 abgesenkt.In this position, the model plate is moved from the rollers arranged in the lifting table onto the empty model car ready. At the same time, a ready-made model plate rolls onto the rollers of the lifting table via the driven rollers of the other model car. Then both model cars return to their starting positions, and the lift table is lowered into the swivel-in level of the turntable 1 with the model plates adopted.

Von dieser Lage aus kann nunmehr die sich in der Maschine befindende Modellplatte ausgewechselt werden.From this position, the model plate in the machine can now be replaced.
