Description

Transportvorrichtung für Gießereikerne und -formenTransport device for foundry cores and molds
Die Erfindung bezieht sich auf eine Transportvor¬ richtung, insbesondere für Gießereikerne und -formen, ge¬ mäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a transport device, in particular for foundry cores and molds, according to the preamble of patent claim 1.
In der Gießereitechnik, insbesondere beim Gießen von Formgußstücken, werden Kerne oder Formen getrennt hergestellt, manuell zusammengeführt und verbunden und anschließend einzeln in eine Schwärzeeinrichtung ge¬ schoben, welche die Kerne mechanisch verspannt, was einen zu großen Platzbedarf mit sich bringt und außer¬ dem nur geringe Haltekraft besitzt.In foundry technology, in particular when casting molded castings, cores or molds are produced separately, manually brought together and connected and then individually pushed into a blackening device which mechanically clamps the cores, which takes up too much space and also only has low holding power.
Die Aufgabe der Erfindung besteht nun darin, ein¬ zelne oder miteinander verbundene Gießereikerne und -formen, im vorliegenden Falle verschraubte Sohlen- und Wassermantelkerne, vollautomatisch und kontinuier¬ lich mit dem Fertigungsrhythmus der Kern- bzw. Formher¬ stellung zu schwärzen oder sonstwie zu behandeln oder zu bearbeiten.The object of the invention is now to blacken or otherwise treat individual or interconnected foundry cores and molds, in the present case screwed sole and water jacket cores, fully automatically and continuously with the production rhythm of the core or mold production or edit.
Die Lösung dieser Aufgabe wird durch die im Kenn¬ zeichen des Patentanspruchs 1 beschriebene technische Lehre vermittelt.This object is achieved by the technical teaching described in the characterizing part of patent claim 1.
Die Vorrichtung gemäß Erfindung ist in einen voll¬ automatisch verketteten Ablauf integriert, der sich im vorliegenden Fall von der Herstellung der Kerne über die Zusammenführung - Verbindung - Schwärzung bis zur Ablage auf ein Trockenband erstreckt. Die( Aufnahme und Halterung auf der Anlage zur Weiterbehandlung, im vor¬ liegenden Fall auf der Schwärzemaschine/ erfolgt in den gleichen platzsparenden Abständen, die auch bei der Fertigung gegeben sind. Die Haltekraft der Lochgrei¬ fer ist stufenlos regelbar. Die Zeichnungen in Verbindung mit der nachfolgen¬ den Beschreibung stellen eine Ausführungsform der Er¬ findung dar.The device according to the invention is integrated in a fully automatically linked process which, in the present case, extends from the production of the cores through the merging - connection - blackening to storage on a drying belt. The (receiving and holding on the plant for further treatment, in the present case on the vor¬ blackness machine / takes place in the same space-saving intervals, which are optionally also in the production. The holding force of Lochgrei¬ fer is infinitely variable. The drawings in conjunction with the following description represent an embodiment of the invention.
Fig. 1 zeigt eine Gesamtansicht der Vorrichtung im Schnitt in Querrichtung an der Linie x-x gemäß Fig. 3a;Fig. 1 shows an overall view of the device in cross section on the line x-x according to Fig. 3a;
Fig. 2 stellt einen Detailschnitt in Querrichtung an der Linie y-y gemäß Fig. 3a dar;FIG. 2 shows a detail section in the transverse direction on the line y-y according to FIG. 3a;
Fig. 3a ist eine schematische Darstellung der Luft¬ versorgung und Steuerung der Vorrichtung, während Fig. 3b eine Teilansicht der Antriebswelle im Schnitt mit den An¬ schlußventilen darstellt;3a is a schematic representation of the air supply and control of the device, while FIG. 3b shows a partial view of the drive shaft in section with the connecting valves;
Fig. 4 zeigt schließlich eine Detailzeichnung des Lochgreifers im Schnitt.Fig. 4 finally shows a detailed drawing of the hole gripper in section.
Die verbundenen Kerne werden mit einer Greifer¬ und Transportvorrichtung 10 von der Verbindungsstelle zur "Aufgabestation" der Schwärzemaschine gebracht und dort auf die Lochgreifer 1 aufgesteckt (pro Takt drei verbundene Kerne) . Danach wird das Transport¬ band 2 um einen Takt weiterbewegt (1.200 mm) . Über ein direkt nach dem Start von der Auflaufleiste ab¬ rollendes Nockenventil 4 wird Luft über die Ringlei¬ tung 3 zu den Lochgreifern 1 geleitet, die sich gegen die Kernwand pressen und damit die Kerne in Position halten. Nach zwei Takten ist die Kerngruppe nach unten hängend in der "Tauchstation" . Hier werden die Kerne durch Anheben eines mit Schwärze gefüllten Beckens ge¬ flutet. Bei den weiteren Taktstrecken tropft die über¬ flüssige Schwärze in ein Becken. An der "Ubergabesta- tion" werden die Lochgreifer 1 durch Auflaufen eines weite¬ ren Nockenventiles 11 auf eine Schiene luftlos gemacht, so daß die Kerngruppe mit einem weiteren Greif- und Transportgerät zu den Trockenöfen gebracht werden kann.The connected cores are brought with a gripper and transport device 10 from the connection point to the "feed station" of the blackening machine and are placed there on the hole grippers 1 (three connected cores per cycle). The conveyor belt 2 is then moved forward by one cycle (1,200 mm). Air is passed via the ring line 3 to the hole grippers 1, which press against the core wall and thus hold the cores in position, via a cam valve 4 rolling off the run-up bar immediately after the start. After two bars the core group is hanging down in the "diving station". Here the cores are flooded by lifting a basin filled with blackness. In the further cycle sections, the superfluous blackness drips into a basin. At the "transfer station", the hole grippers 1 are made airless by running a further cam valve 11 onto a rail, so that the core group can be brought to the drying ovens with another gripping and transport device.
Die Abstände der Lochgreifer 1 stellen sich beim Durchlaufen einer Kulisse 13, die mit einer Spindel 9 auf den typengebundenen Abstand gebracht wird, selbsttätig ein.The distances between the hole grippers 1 are set automatically when passing through a link 13, which is brought to the type-specific distance with a spindle 9.
Die Hauptluf zuführung erfolgt über einen Dreh¬ verteiler 6 auf der Antriebswelle 5 zu drei federnd angebrachten Anschlußstücken 7, welche durch Nocken¬ ventile, die durch auf der Antriebswelle 5 befind¬ liche Auflaufstücke betätigt werden, immer zu den An¬ schlußstücken 7, die sich in der jeweiligen Position im Kontakt mit dem an dem Transportband 2 befindlichen Gegenstück befinden.The main air supply takes place via a rotary distributor 6 on the drive shaft 5 to three resiliently attached connecting pieces 7, which are actuated by cam valves which are actuated by thrust pieces located on the drive shaft 5, always to the connecting pieces 7, which are in the respective position in contact with the counterpart located on the conveyor belt 2.
Das ins Leere laufende Anschlußstück 7 wird durch Ablaufen des betreffenden Nockenventiles 4 vom Auflauf¬ stück verschlossen.The connecting piece 7, which runs into empty space, is closed by the run-up piece of the relevant cam valve 4.
Die Betätigung der fünfzehn Kontaktstücke 12 (öffnen und Schließen) erfolgt mechanisch durch die Bewegung des Transportbandes 2 durch Auflaufen der Betätigungs¬ hebel, d. h. im Taktlauf sind nur die beiden Gegen¬ stücke geöffnet, die sich gerade im Kontakt mit den federnd gelagerten Anschlußstücken 7 befinden. The actuation of the fifteen contact pieces 12 (opening and closing) is carried out mechanically by the movement of the conveyor belt 2 by the actuating levers, ie. H. only the two counterparts that are currently in contact with the spring-mounted connecting pieces 7 are opened in the cycle.
