Description

Im Hauptpatent 938 0922 ist eine Steuervorrichtung für Gießerei-Formmaschinen beschrieben, bei der eine Mehrzahl von einzelnen vorzugsweise pneumatischen Hilfskraftschaltern von einer gemeinsamen Steuerwelle betätigt werden. Die Anordnung ist .dabei -so gewählt, daß die Hilfskraftschalter in einem in die Maschine eingebauten Steuerkasten untergebracht sind, in dem (die Steuerwelle axial verschiebbar und zugleich drehbar gelagert ist. Da die beanspruchten Teile, z. B. die Dichtungen der Hilfskraftschalter, einer gewissen Abnutzung unterliegen und gegebenenfalls erneuert werden müssen, hat es sich als zweckmäßig erwiesen;- erfindungsgemäß die Steuerwelle in abneh mbaren Lagern zu lagern. Die Steuerwelle kann dann zusammen mit den geschlossen bleibenden Lagern und ihren Anschlagmitteln herausgenommen werden, "so daß eine Reparatur der eingebaut bleibenden Hilfskraftschalter möglich ist. Andererseits ist nach dem Wiedereinsetzen der Lagerungen mit der Steuerwelle eine Neueinstellung und Justierung der Welle nicht erforderlich. Das Abnehmen der Steuerwelle mit ihren Lagerungen hat auch den Vorteil, da13 in dem rauhen Gießereibetrieb die Lagerflächen nicht beschädigt oder verschmutzt werden können.The main patent 938 0922 describes a control device for foundry molding machines in which a plurality of individual, preferably pneumatic, auxiliary power switches are actuated by a common control shaft. The arrangement is .dabei - chosen so that the auxiliary power switch are accommodated in a built into the machine control box, axially displaceable in the (control shaft and is supported at the same time rotatable since the stressed parts such, as the seals of the auxiliary power switch, a.. subject to certain wear and tear and may have to be replaced, it has proven to be expedient; - according to the invention, to store the control shaft in removable bearings On the other hand, after reinserting the bearings with the control shaft, readjustment and adjustment of the shaft is not necessary. Removing the control shaft with its bearings also has the advantage that the bearing surfaces cannot be damaged or soiled in the rough foundry operation.

Die Abbildung zeigt ass Ausführungsbeispiel der verbesserten Anordnung den im Hauptpatent näher beschriebenen Steuerkasten r mit den darin untergebrachten Steuerventilen 2, 3, 4 und 5, die durch die gemeinsame Steuerwelle 7 betätigt werden. Die Steuerwelle 7 ist jedoch nicht fest im Steuerkasten z gelagert, sondern in herausnehmbaren Lagern 13, 13' die mittels Schrauben 14 am Steuerkasten r befestigt sind. Löst man die Schrauben 14, so kann man die Steuerwelle 7 samt ihren Lagerungen 13, 13' bequem abnehmen. Es wird dadurch genügend Raum geschaffen, um die Verschraubungen 15 der Ventile 2 bis 5 lösen und die Ventilstößel 2' bis 5' nach unten herausziehen und neue Dichtungen einsetzen zu können.As an embodiment of the improved arrangement, the figure shows the control box r described in more detail in the main patent with the control valves 2, 3, 4 and 5 housed therein, which are actuated by the common control shaft 7. The control shaft 7, however, is not permanently mounted in the control box z, but in removable bearings 13, 13 'which are fastened to the control box r by means of screws 14. If the screws 14 are loosened, the control shaft 7 together with its bearings 13, 13 ' can be easily removed. This creates enough space to loosen the screw connections 15 of the valves 2 to 5 and to pull out the valve tappets 2 'to 5' downwards and to be able to insert new seals.

Sinngemäße Anordnungen ergeben sich bei anderen Ausführungsformen der im Hauptpatent behandelten Steuervorrichtung.Similar arrangements result in other embodiments the control device dealt with in the main patent.
