Die in den Figuren gezeigte Niederdruck-Kokillen-Giesseinrichtung weist ein portalartiges Gestell 10 mit am Giessereiboden abgestützten vier vertikalen Säulen 11 auf, die obenends mittels Längs- und Querträgern 12, 12' miteinander verbunden sind. An den Längsträgern 12 ist eine horizontale Tragplatte 14 befestigt, auf welcher zwei Drehtische 16, 18 angeordnet sind. Die gemeinsame, in vertikaler Richtung verlaufende Drehachse der beiden übereinander angeordneten Drehtische 16, 18 ist mit 20 bezeichnet.The low-pressure mold casting device shown in the figures has Portal-like frame 10 with four vertical supports supported on the foundry floor Columns 11 on top of each other by means of longitudinal and cross members 12, 12 ' are connected. On the side members 12 is a horizontal support plate 14 attached, on which two rotary tables 16, 18 are arranged. The common vertical axis of rotation of the two Rotary tables 16, 18 arranged one above the other are designated by 20.

Koaxial zur Drehachse 20 sitzt auf der Tragplatte 14 mit seiner Stirnseite ein erstes Axial-Kugellager 22, auf dem andererseits der ringartige untere Drehtisch 16 angeordnet ist - vergleiche insbesondere Fig. 3. Auf diesem sitzt ebenfalls koaxial zur Drehachse 20 ein gleich ausgebildetes zweites Axial-Kugellager 24, auf dem der obere Drehtisch 18 angeordnet ist. Der mit dem unteren Drehtisch 16 fest verbundene radial aussenliegende Ring 22' des ersten Axial-Kugellagers sowie der mit dem oberen Drehtisch 18 fest verbundene radial aussenliegende Ring 24' des zweiten Axial-Kugellagers 24 sind mit einer umlaufenden Stirnverzahnung 26 versehen, mit welcher ein Ritzel 28 eines zugeordneten Drehantriebs 30 bzw. 32 kämmt. Jeder der Drehantriebe 30, 32 weist einen von einer Steuereinrichtung 34 angesteuerten, am Gestell 10 befestigten Elektromotor mit einem Indexiergetriebe auf, auf dessen Abgangswelle das jeweilige Ritzel 28 sitzt.Coaxial with the axis of rotation 20 sits on the support plate 14 with its end face a first axial ball bearing 22, on the other hand, the ring-like lower Rotary table 16 is arranged - compare in particular Fig. 3. On this also sits coaxially to the axis of rotation 20 of the same design second Axial ball bearing 24 on which the upper turntable 18 is arranged. Of the with the lower rotary table 16 fixed radially outer ring 22 'of the first axial ball bearing and the one with the upper rotary table 18 firmly connected radially outer ring 24 'of the second axial ball bearing 24 are provided with a circumferential spline 26, with which meshes a pinion 28 of an associated rotary drive 30 or 32. Each of the rotary drives 30, 32 has one from a control device 34 controlled, attached to the frame 10 electric motor with an indexing gear on whose output shaft the respective pinion 28 is seated.

Die Tragplatte 14 weist einen kreisförmigen Durchlass 36 auf, der von einem zur Drehachse 20 koaxialen Tragrohr 38' eines ersten Tragelements 38 mit Spiel durchgriffen ist. Dieses Tragrohr 38' ist obenends am unteren Drehtisch 16 bei dessen radial innenliegendem Rand befestigt. Innerhalb dieses Tragrohres 38' ist koaxial, ebenfalls mit Spiel, ein weiteres Tragrohr 40' eines weiteren Tragelements 40 angeordnet. Dieses ist mit seiner obenliegenden Stirnseite am oberen Drehtisch 18 befestigt. Die beiden Tragrohre 38', 40' enden in einer Horizontalebene unterhalb der Längsträger 12 und weisen je eine in Richtung gegen oben zurückversetzte Ausnehmung auf. An der Stirnseite der dadurch gebildeten vorstehenden Rohrsegmente 38'' bzw. 40'' ist je ein in radialer Richtung gegen aussen abstehender, zwei parallele Tragprofile aufweisender Ausleger 44 befestigt. Im radialen Endbereich jedes dieser beiden Ausleger 44 ist ein Manipulator 46 gleichen Aufbaus angeordnet, siehe insbesondere Fig. 1. Die Ausnehmungen sind derart ausgebildet, dass die beiden Manipulatoren 46 um die Drehachse 20 relativ zueinander von ca. 80° bis ca. 280° drehen können.The support plate 14 has a circular passage 36, which from a support tube 38 'of a first support element coaxial with the axis of rotation 20 38 is reached with play. This support tube 38 'is at the top at the bottom Turntable 16 attached to its radially inner edge. Within this support tube 38 'is coaxial, also with play, another support tube 40 'of a further support element 40 is arranged. This is with his attached to the upper end of the upper turntable 18. The two Support tubes 38 ', 40' end in a horizontal plane below the side members 12 and each have a recess set back towards the top on. On the end face of the protruding pipe segments thus formed 38 '' or 40 '' is a protruding in the radial direction towards the outside, two arms 44 having parallel support profiles attached. In the radial The end region of each of these two arms 44 is a manipulator 46 same structure, see in particular Fig. 1. The recesses are designed such that the two manipulators 46 about the axis of rotation 20 can rotate relative to each other from about 80 ° to about 280 °.

Wie weiter der Fig. 3 entnehmbar ist, sitzt auf dem oberen Drehtisch 18 eine Drehdurchführung 48 für die Verbindung der von der Steuereinrichtung 34 herkommenden Steuer- und Speiseleitungen mit den Manipulatoren 46. Für die Verbindung zwischen dem drehtellerfesten Teil der Drehdurchführung 48 mit dem am inneren Tragrohr 40' angeordneten Manipulator 66 können starre Leitungen verwendet werden, wogegen zur Verbindung mit dem anderen Manipulator flexible Leitungen vorzusehen sind, die die gegenseitige unterschiedliche Drehlage aufnehmen können.As can be seen further from FIG. 3, sits on the upper rotary table 18 a rotating union 48 for the connection of the control device 34 coming control and feed lines with the manipulators 46. For the connection between the part of the rotating union fixed to the turntable 48 with the manipulator arranged on the inner support tube 40 ' 66 rigid lines can be used, whereas for connection flexible lines are to be provided with the other manipulator, which the mutually different rotational position can take up.

Im gleichen Abstand zur Drehachse 20 ist an jedem der Ausleger 44 ein in vertikaler Richtung verlaufendes Tragprofil 50 des Manipulators 46 in vertikaler Richtung heb- und senkbar angeordnet. Am unteren Ende des Tragprofils 50 ist ein Schienenprofil 52 um eine bezüglich der Drehachse 20 in tangentialer Richtung verlaufende Achse 54 drehbar gelagert. Das Schienenprofil 52 ist mittels eines entsprechenden Antriebs um die Achse 54 von einer in horizontaler Richtung verlaufenden, in eine in vertikaler Richtung verlaufende Lage und wieder zurück verschwenkbar. Am Schienenprofil 52 ist einerseits ein auslegerartiges Tragorgan 56 fest angeordnet und andererseits ein Schlitten 58 auf das Tragorgan 56 zu und von diesem weg verschiebbar gelagert. Am Tragorgan 56 und Schlitten 58 sind um zur Achse 54 parallele Schwenkachsen 60 Träger 62 verschwenkbar gelagert, die an ihren freien Enden je ein Kokillenteil 64, 64' einer Kokille 66 tragen. In Arbeitsstellung sind die Träger 62 mit ihren freien Enden aufeinander zu fluchtend ausgerichtet und verlaufen parallel zum Schienenprofil 52. In Schliessstellung liegen dabei die Kokillenteile 64, 64' stirnseitig aneinander an, wie dies in der Fig. 1 beim links gezeigten Manipulator 46 der Fall ist. Beim rechts gezeigten Manipulator befinden sich die Kokillenteile 64, 64' in voneinander beabstandeter Offenstellung; diese wurde durch Bewegen des Schlittens 58 vom Tragprofil 50 weg erreicht.At the same distance from the axis of rotation 20 there is an in at each of the arms 44 vertical profile of the manipulator 46 in the vertical Direction can be raised and lowered. At the lower end of the support profile 50 is a rail profile 52 about an axis of rotation 20 in tangential direction axis 54 rotatably mounted. The rail profile 52 is by means of a corresponding drive about the axis 54 from a horizontal direction to a vertical direction current position and swiveling back again. On the rail profile 52, on the one hand, a cantilever-like support member 56 is fixed and on the other hand a carriage 58 to and from the support member 56 slidably mounted away. On the support member 56 and carriage 58 are to Axis 54 parallel pivot axes 60 supports 62 pivotably mounted, which each carry a mold part 64, 64 'of a mold 66 at their free ends. In the working position, the carriers 62 are towards one another with their free ends aligned and run parallel to the rail profile 52. In In this closed position, the mold parts 64, 64 'lie against one another on the end face on, as is the case in FIG. 1 with the manipulator 46 shown on the left. In the manipulator shown on the right, the mold parts 64, 64 'are in spaced open position; this was achieved by moving the Carriage 58 reached away from the support profile 50.

Der Abstand der Achsen 54 von der Drehachse 20 ist gleich gross und in der Fig. 1 mit R bezeichnet. Die Manipulatoren 46 können somit entlang eines Drehkreises 68 - siehe Fig. 2 - um die Drehachse 20 zu Arbeitsstationen 70 bewegt werden. Es versteht sich von selbst, dass diese Arbeitsstationen 70 entlang dem Drehkreis 68 in Umfangsrichtung hintereinander angeordnet sind.The distance between the axes 54 from the axis of rotation 20 is the same size and in 1 labeled R. The manipulators 46 can thus along a rotating circle 68 - see FIG. 2 - about the axis of rotation 20 to work stations 70 are moved. It goes without saying that these workstations 70 along the rotating circle 68 in the circumferential direction one behind the other are.

In der Fig. 1 ist rechts eine Kern-Einlegestation 72 und links eine Giessstation 74 dargestellt. Wie dies aus der Fig. 2 hervorgeht, sind diese beiden Stationen 72, 74 in einem Winkel von etwa 160° bezüglich der Drehachse 20 zueinander angeordnet. Die Giessstation 74 weist einen Schmelzofen 76 bekannter Bauart mit einem in einen oberhalb des Schmelzofens 76 angeordneten Giessmund 78 mündenden Steigrohr 80 auf. 1 is a core insertion station 72 on the right and a casting station on the left 74 shown. As can be seen from Fig. 2, these are two Stations 72, 74 at an angle of approximately 160 ° with respect to the axis of rotation 20 arranged to each other. The casting station 74 has a melting furnace 76 known type with one arranged in a above the melting furnace 76 Pipe 80 opening riser pipe 80.

In Drehrichtung D gesehen, folgt der Giessstation 74 eine Entnahmestation 82 mit einem Wegförderer 84 für die aus der Kokille 66 ausgestossenen Gussstücke und dann eine Schlichtstation 86 mit einem Schlichtbad 88. Die Entnahmestation 82 ist zur Giessstation 74 und die Schlichtstation 86 zur Kern-Einlegestation 72 in einem Winkel von ca. 80° angeordnet.Seen in the direction of rotation D, the casting station 74 is followed by a removal station 82 with a conveyor 84 for those ejected from the mold 66 Castings and then a sizing station 86 with a sizing bath 88. The removal station 82 is to the casting station 74 and the finishing station 86 to the core insertion station 72 at an angle of approximately 80 °.

Zwischen der Kern-Einlegestation 72 und der Giessstation 74 ist auf der der Entnahme- und Schlichtstation 82, 86 abgewandten Seite eine Servicestation 90 mittig angeordnet. Diese weist eine, auf rechtwinklig zu einer Radialen 90' verlaufenden Schienen 92 verfahrbare Strahleinrichtung 94 zum Strahlreinigen der Kokillenteile 64, 64' auf. In der Fig. 2 befindet sich die Strahleinrichtung 94 in Arbeitsstellung. Wird sie aus dieser in Richtung des Pfeiles A in eine Ruhestellung verschoben, wird für einen allfälligen Wechsel der Kokillen Zugang geschaffen. Der Kokillenwechsel kann entweder von Hand oder mittels einer nicht gezeigten Kokillenwechseleinrichtung erfolgen.Between the core insertion station 72 and the casting station 74 is on the a service station on the side facing away from the removal and finishing station 82, 86 90 arranged in the middle. This has one at right angles to one Radial 90 'running rails 92 movable beam device 94 for jet cleaning the mold parts 64, 64 '. 2 is located in the jet device 94 in the working position. She will head out of this of arrow A is moved to a rest position, for a possible Change of mold access created. The mold change can either by hand or by means of a mold changing device, not shown respectively.

Bezüglich Aufbau und Funktionsweise der Manipulatoren 46 und der Arbeitsstationen wird auch auf EP-A-0 398 168 verwiesen.Regarding the structure and functioning of the manipulators 46 and the work stations reference is also made to EP-A-0 398 168.

Da, wie im Zusammenhang mit der Fig. 3 weiter oben beschrieben, die beiden Manipulatoren 46 relativ zueinander zwischen etwa 80 und 280° um die Drehachse 20 gedreht werden können, können sie sich in benachbarten Arbeitsstationen 70 gleichzeitig befinden, mit Ausnahme der Entnahmestation 82 und Schlichtstation 86.Since, as described in connection with FIG. 3 above, the two Manipulators 46 relative to each other between about 80 and 280 ° the axis of rotation 20 can be rotated, they can be in neighboring Workstations 70 are located at the same time, with the exception of the removal station 82 and finishing station 86.

Die Funktionsweise der in den Fig. 1 bis 3 gezeigten Niederdruck-Kokillen-Giesseinrichtung wird nun anhand der Fig. 4 bis 8 näher erläutert. In der Fig. 4 befindet sich einer der Manipulatoren 64 in Giessstellung, wo die in Schliessstellung verbrachten Kokillenteile 64, 64', wie auch in der Fig. 3 links gezeigt, auf den Giessmund 78 abgesenkt sind. Das Schienenprofil 52 befindet sich dabei in radialer Lage. Durch Erhöhen des Drucks im Gasvolumen im Innern des Schmelzofens 76 oberhalb der Schmelze, wird diese durch das Steigrohr 80 und den Giessmund 78 hindurch in die Kokille 66 gefördert. Nach Abschluss des Giessvorgangs wird die Kokille 66 durch Anheben des Tragprofils 50 vom Giessmund 78 abgehoben und durch Antreiben des zugeordneten Drehtisches 16 bzw. 18 zur Entnahmestation 82 verbracht. Dort werden, wie dies Fig. 5 zeigt, die beiden Kokillenteile 64, 64' durch Verschieben des Schlittens 58 in Offenstellung voneinander getrennt. Durch Aktivieren von Ausstosselementen 96 werden die Gussstücke aus dem betreffenden Kokillenteil 64, 64' ausgestossen, welche auf den Wegförderer 84, beispielsweise ein Förderband, fallen.The mode of operation of the low-pressure mold casting device shown in FIGS. 1 to 3 will now be explained in more detail with reference to FIGS. 4 to 8. In the Fig. 4 is one of the manipulators 64 in the casting position, where the in Mold parts 64, 64 'were in the closed position, as in FIG. 3 shown on the left, to which Giessmund 78 are lowered. The rail profile 52 is in a radial position. By increasing the pressure in the gas volume inside the melting furnace 76 above the melt, this is through the riser pipe 80 and the pouring mouth 78 into the mold 66 promoted. After the casting process is complete, the mold 66 is moved through Lifting the support profile 50 lifted from the pouring mouth 78 and by driving of the assigned rotary table 16 or 18 to the removal station 82 spent. 5, the two mold parts 64, 64 'separated from each other by moving the carriage 58 in the open position. By activating ejection elements 96, the castings become ejected from the relevant mold part 64, 64 ', which on the conveyor 84, for example a conveyor belt, fall.

Nun wird der Manipulator 46 über das Schlichtbad 88 gedreht und abgesenkt. Dabei werden bei sich in Offenstellung befindlichem Schlitten 58 die Träger 62 um die Schenkachsen 60 um 90° in eine Lage verschwenkt, in welcher sie vom Schienenprofil 52 rechtwinklig weg zeigen, wodurch die Kokillenteile 64, 64' unter Vermeidung von Luftpolsterbildung an den Ausnehmungen der Kokillenteile 64, 64' in das Schlichtbad 88 eintauchen, wie dies Fig. 6 zeigt. Nach kurzem Eintauchen wird der Manipulator 46 wieder angehoben und werden die Träger 62 in die miteinander fluchtende Arbeitsstellung zurückverschwenkt.The manipulator 46 is now rotated and lowered over the size bath 88. The carriage 58 is in the open position Carrier 62 pivoted about the pivot axes 60 by 90 ° into a position in which they point away from the rail profile 52 at a right angle, whereby the Mold parts 64, 64 'while avoiding the formation of air cushions on the recesses immerse the mold parts 64, 64 'in the sizing bath 88, such as this shows Fig. 6. After a brief immersion, the manipulator 46 becomes again raised and the carriers 62 are in the aligned working position swiveled back.

Durch erneutes Drehen des Manipulators 46 um die Drehachse 20 gelangt er zur Kern-Einlegestation 72. Um ein sauberes und einfaches Einlegen der Kerne zu ermöglichen, wird das Schienenprofil 52 um die Achse 54 in eine vertikale Lage verschwenkt, wobei das früher innenliegende Ende des Schienenprofils 52 nun nach unten zu liegen kommt. Die nun horizontalen Kokillenteile 64, 64' kommen dadurch in radialer Richtung gesehen ausserhalb des Schienenprofils 52 zu liegen und sind frei zugänglich. Sobald der Kern durch eine Bedienungsperson oder einen Kern-Einlegeautomaten in das untenliegende Kokillenteil 64 eingelegt ist, wird durch Verschieben des Schlittens 58 auf das Tragorgan 56 zu, die Kokille 66 geschlossen. Durch entgegengesetztes Drehen des Schienenprofils 52 um die Achse 54 und Drehen des Manipulators 64 zur Giessstation 74 ist ein Arbeitszyklus beendet.By turning the manipulator 46 again about the axis of rotation 20 he to the core insertion station 72. For a clean and easy insertion of the To enable cores, the rail profile 52 is about the axis 54 in one vertical position pivoted, the formerly inner end of the Rail profile 52 now comes to lie down. The now horizontal As a result, mold parts 64, 64 'come outside as seen in the radial direction the rail profile 52 to lie and are freely accessible. Once the Core by an operator or a core loading machine in the lower mold part 64 is inserted by moving the Carriage 58 towards support member 56, mold 66 closed. By opposite rotation of the rail profile 52 about the axis 54 and Turning the manipulator 64 to the casting station 74 has ended a work cycle.

Da die beiden Manipulatoren 46 unabhängig voneinander um die Drehachse 20 bewegbar sind, können sich diese gleichzeitig bei der Kern-Einlegestation und bei der Giessstation 74 befinden. Die Vorgänge in diesen beiden Arbeitsstationen 70 benötigen wesentlich längere Zeit als das Ausstossen der Gussstücke in der Entnahmestation 82 und das Eintauchen der Kokillenteile 64, 64' in das Schlichtbad 88. Befindet sich der eine Manipulator in der Kern-Einlegestation 72, kann sich der andere Manipulator 46 nach Beenden des Giessvorgangs von der Giessstation 74 zur Entnahmestation 82 und dann zur Schlichtetation 86 bewegen. Dieser Manipulator 46 kann dann in die Kern-Einlegestation 72 gedreht werden, wenn der andere Manipulator 46 die Kern-Einlegestation 72 in Richtung zur Giessstation 74 verlassen hat.Since the two manipulators 46 are independent of one another about the axis of rotation 20 are movable, they can be simultaneously at the core insertion station and are at the casting station 74. The operations in these two Workstations 70 take significantly longer time than purging the castings in the removal station 82 and the immersion of the mold parts 64, 64 'into the sizing bath 88. There is one manipulator in the core insertion station 72, the other manipulator 46 can follow End the pouring process from the pouring station 74 to the removal station 82 and then move to the sizing station 86. This manipulator 46 can then be rotated into the core loading station 72 when the other manipulator 46 leave the core insertion station 72 in the direction of the casting station 74 Has.

Jeweils nach einer bestimmten Anzahl Arbeitszyklen sind die Kokillenteile 64, 64' durch Bestrahlen, beispielsweise mit Messingschrot, zu reinigen. Zu diesem Zweck wird der betreffende Manipulator 46 in die Servicestation 90 gedreht. Während die Kokillenteile 64, 64' mittels der Strahleinrichtung 94 behandelt werden, geht die Produktion mittels des anderen Manipulators 46 durch Drehen in und entgegen der Drehrichtung D weiter. Nach dem Einlegen eines Kerns in die Kokille 66 wird dieser Manipulator 46 von der Kern-Einlegestation 72 entgegen der Drehrichtung D zur Giessstation 74 bewegt und auf den Giessmund 78 abgesenkt. Nach Beendigung des Giessvorgangs wird der Manipulator 46 in Drehrichtung D zur Entnahmestation 82 gedreht, wo das Giessstück aus der Kokille 66 ausgestossen und dem Wegförderer 84 zugeführt wird. Dann wird der Manipulator 46 zur Schlichtstation 86 verbracht und nach dem kurzen Eintauchen der Kokillenteile 64, 64' in das Schlichtbad 88 in die Kern-Einlegestation 72 weiterbewegt. Die Kokille 66 ist nun für einen weiteren Arbeitszyklus bereit.The mold parts are after a certain number of work cycles 64, 64 'to be cleaned by irradiation, for example with brass shot. For this purpose, the manipulator 46 in question is brought into the service station 90 rotated. During the mold parts 64, 64 'by means of the jet device 94 are treated, the production goes by means of the other manipulator 46 by turning in and against the direction of rotation D. After the insertion of a core into the mold 66, this manipulator 46 of the core insertion station 72 against the direction of rotation D to the casting station 74 moved and lowered onto the pouring mouth 78. After completing the During the pouring process, the manipulator 46 becomes the removal station in the direction of rotation D. 82 rotated where the casting is ejected from the mold 66 and the conveyor 84 is fed. Then the manipulator 46 to the finishing station 86 and after briefly immersing the mold parts 64, 64 'moved into the sizing bath 88 in the core insertion station 72. The mold 66 is now ready for another working cycle.

Auch bei einem Wechsel der Kokillenteile 64, 64' wird der betreffende Manipulator 46 in die Servicestation 90 gedreht, wobei während der Demontage der alten Kokillenteile 64, 64' und Montage der neuen Kokillenteile mit dem anderen Manipulator 46 die Produktion von Gussstücken aufrechterhalten werden kann.Even if the mold parts 64, 64 'are changed, the relevant part becomes Manipulator 46 rotated into the service station 90, during the disassembly the old mold parts 64, 64 'and assembly of the new mold parts maintain the production of castings with the other manipulator 46 can be.

Die in der Zeichnung skizzierte Ausbildungsform der Niederdruck-Kokillen-Giesseinrichtung weist eine äusserst gedrängte Bauweise auf. Das dabei nicht ermöglichte gleichzeitige Plazieren der beiden Manipulatoren 46 in der Entnahmestation 82 und der Schlichtstation 86 führt aber zu keiner oder zu einer nur unerheblichen Verlängerung eines Arbeitszyklus, da in diesen beiden Arbeitsstationen 70 die benötigte Zeitdauer viel kürzer ist als in der Kern-Einlegestation 72 und Giessstation 74.The design of the low-pressure mold casting device outlined in the drawing has a very compact design. That included not enabled simultaneous placement of the two manipulators 46 in the The removal station 82 and the finishing station 86, however, lead to none or to an insignificant extension of a work cycle, because in these two Workstations 70 the time required is much shorter than in the Core insertion station 72 and casting station 74.

Über die Indexiertriebe der beiden Drehantriebe 30 und 32 kennt die Steuereinrichtung 34 die Position der beiden Manipulatoren 46. Dadurch ist eine zeitoptimale Steuerung der Arbeitsabläufe bei Verhinderung des Zusammenstosses der beiden Manipulatoren 46 bzw. deren Aufhängungen gewährleistet.Knows about the indexing drives of the two rotary drives 30 and 32 Control device 34, the position of the two manipulators 46. This is a time-optimal control of the work processes while preventing the collision of the two manipulators 46 and their suspensions guaranteed.

Selbstverständlich ist es auch denkbar, die Arbeitsstationen 70 entlang dem Drehkreis 68 gleichmässig zu verteilen und/oder Tragelemente 38, 40 der Manipulatoren 46 derart auszubilden, dass immer die beiden Manipulatoren 46 in benachbarten Arbeitsstationen 70 angeordnet sein können.Of course, it is also conceivable to run along the work stations 70 to distribute the rotating circle 68 evenly and / or support elements 38, 40 of the manipulators 46 in such a way that the two manipulators always 46 can be arranged in adjacent workstations 70.

Selbstverständlich ist es auch denkbar, dass das Gestell 10 eine vom Giessereiboden abstehende Tragachse aufweist, an der die beiden Manipulatoren 46 drehbar angeordnet sind. Diese Ausbildungsform benötigt aber mehr Platz als bei portalartiger Ausbildung des Gestells 10.Of course, it is also conceivable that the frame 10 one of the Foundry floor protruding support axis on which the two manipulators 46 are arranged rotatably. However, this type of training requires more space than with portal-like design of frame 10.

Das von den übrigen Arbeitsstationen 70 getrennte Vorsehen einer Servicestation 90, bringt wie weiter oben beschrieben, den Vorteil, dass auch währenddem sich einer der Manipulatoren 46 in der Servicestation 90 befindet, mit dem anderen Manipulator 46 weiter produziert werden kann. Wird auf diesen Vorteil verzichtet, kann selbstverständlich die Servicestation 90 beispielsweise der Entnahmestation 82 zugeordnet werden.The provision of a service station separate from the other workstations 70 90, as described above, brings the advantage that also while one of the manipulators 46 is in the service station 90, can be produced with the other manipulator 46. If this advantage is waived, the service station can of course 90, for example, can be assigned to the removal station 82.
