Description

Die Erfindung betrifft eine kombinierte Werkzeugmontage- und Inspektionsvorrichtung mit einem Werkzeugträger mit einer doppelten und um eine horizontale Achse drehbaren Werkzeugaufnahme zum Anbau an Kern- und Maskenschießmaschinen nach DE-PS 31 48 461.The invention relates to a combined tool assembly and inspection device with a tool holder with a double tool holder rotatable about a horizontal axis for attachment to core and mask shooting machines according to DE-PS 31 48 461.

Aus der DE-PS 31 48 461 ist eine Kern- und Maskenschießmaschine mit einem Maschinenständer, einem Werkzeugträger, einer Schießvorrichtung und einer Entnahmevorrichtung bekannt, die dadurch gekennzeichnet ist, daß der Werkzeugträger mit einer doppelten, um eine horizontale Achse drehbaren Werkzeugaufnahme und einer damit zusammenwirkenden, aus zwei miteinander verbundenen Schußkesseln bestehenden und um eune vertikale Achse schwenkbaren Schießvorrichtung ausgestattet ist.From DE-PS 31 48 461 a core and mask shooting machine with a machine stand, a tool holder, a shooting device and a removal device is known, which is characterized in that the tool holder with a double, rotatable about a horizontal axis tool holder and interacting with it , consisting of two interconnected shot boilers and pivoting about a vertical axis shooting device.

Diese bekannte Maschine besitzt den Nachteil, daß das zu wechselnde Werkzeug mit Hilfe eines Krans an die Aufspannfläche herangeführt und die Verbindung manuell durch Verschrauben der beiden Teile hergestellt werden muß. Diese Maßnahme ist zeitaufwendig und die Maschine muß dabei stillgesetzt werden.This known machine has the disadvantage that the tool to be changed is brought up to the clamping surface with the aid of a crane and the connection has to be made manually by screwing the two parts together. This measure is time consuming and the machine must be shut down.

Die Aufgabe der Erfindung besteht nun darin eine Vorrichtung zu schaffen mit der es möglich ist, bei Maschinen der bekannten Art das Heranführen des Werkzeugs an die Aufnahmefläche und das Verspannen desselben auf der Maschine automatisch und bei laufender Maschine vorzunehmen.The object of the invention is to provide a device with which it is possible, in machines of the known type, to bring the tool closer to the receiving surface and to brace it on the machine automatically and with the machine running.

Die Lösung dieser Aufgabe wird durch die technische Lehre vermittelt, daß die Vorrichtung aus einem mit einem fahrbaren und mechanisch betätigten Schlitten ausgerüsteten Grundrahmen, einem klappbaren mechanisch betätigten Tisch mit Zylinder und Greifvorrichtung und einer Werkzeug- aufnahme mit Greifvorrichtung und Armgreifern zum Festhalten der feststehenden und der beweglichen Werkzeughälfte besteht.The solution to this problem is conveyed by the technical teaching that the device consists of a base frame equipped with a movable and mechanically operated slide, a foldable mechanically operated table with cylinder and gripping device and a tool holder with gripping device and arm grippers for holding the fixed and movable tool half.

Mit Hilfe der erfindungsgemäßen Vorrichtung wird mit einem fahrbaren Schlitten ein klappbarer Tisch mit dem Werkzeug an die Werkzeugaufnahme der Maschine herangeführt und verspannt. Dieser ersten automatisch durchgeführten Werkzeugmontagestufe folgt die zweite automatische Inspektions- und Reinigungsstufe durch Trennung der beiden Werkzeughälften, sodaß eine Inspektion und Reinigung der beiden Werkzeughälften durchgeführt werden kann. Während dieser Zeit kann die Maschine weiterlaufen. Mit der kombinierten Werkzeugmontage- und Inspektionsvorrichtung können der Werkzeug-Aufnahme nicht nur automatisch komplette Werkzeuge zugeführt beziehungsweise von dieser abgenommen werden, sondern es kann auch nur eine Werkzeughälfte abgezogen werden.With the aid of the device according to the invention, a foldable table with the tool is brought to the tool holder of the machine and clamped with a movable carriage. This first automatically performed tool assembly stage is followed by the second automatic inspection and cleaning stage by separating the two tool halves, so that an inspection and cleaning of the two tool halves can be carried out. The machine can continue to run during this time. With the combined tool assembly and inspection device, not only can complete tools be automatically supplied to or removed from the tool holder, but only one tool half can also be removed.

Die erfindungsgemäße Vorrichtung bietet erhebliche Vorteile gegenüber bekannten Einrichtungen, da die komplizierte Positionierung der schweren Werkzeuge zum Befestigen am Werkzeugträger der Aufnahmevorrichtung entfällt. Zu diesem Zweck wird das komplette Werkzeug, bestehend aus den Hälften, auf eine klappbare Tischfläche aufgesetzt und durch den fahrbaren Schlitten an den Werkzeugträger der Aufnahme herangefahren.The device according to the invention offers considerable advantages over known devices, since the complicated positioning of the heavy tools for fastening to the tool holder of the receiving device is eliminated. For this purpose, the complete tool, consisting of the halves, is placed on a foldable table surface and by the mobile carriage on the tool carrier of the Approach the recording.

Ebenso kann diese Vorrichtung dazu eingesetzt werden, um ein Werkzeug zu öffnen. Eine erhebliche Zeiteinsparung für die Inspektion, Reinigung oder für kleinere Reparaturen ist damit verbunden, da das Werkzeug nicht von der Maschine genommen und durch komplizierte Arbeitsgänge getrennt werden muß.This device can also be used to open a tool. This saves a considerable amount of time for inspection, cleaning or minor repairs, since the tool does not have to be removed from the machine and separated by complicated operations.

Hierzu wird die Tischfläche abgeklappt und parallel eine mechanische Greifvorrichtung eingeklappt. Nach dem Beifahren an die rechte Werkzeughälfte und Aktivieren der mechanischen Greifvorrichtung beziehungsweise Reaktivieren derselben in der Werkzeugaufnahmevorrichtung kann eine Werkzeughälfte durch den horizontalen Schlitten abgezogen werden.For this purpose, the table surface is folded down and a mechanical gripping device is folded in parallel. After moving to the right half of the tool and activating the mechanical gripping device or reactivating the same in the tool holding device, a half of the tool can be pulled off by the horizontal slide.

Die Zeichnung erläutert eine Ausführungsform der Erfindung.The drawing explains an embodiment of the invention.

Fig. 1 zeigt schematisch die Bereitstellung des Werkzeugs vor der Montage, während Fig. 2 das an die Kern- und Maskenschießmaschine montierte Werkzeug und die erfindungsgemäße Vorrichtung in Ruhestellung darstellt.Fig. 1 shows schematically the provision of the tool before assembly, while Fig. 2 shows the tool mounted on the core and mask shooting machine and the device according to the invention in the rest position.

Aus Fig. 3 ist das an die Maschine montierte Werkzeug zu entnehmen, dessen eine Hälfte gemäß Fig. 4 von der Montagevorrichtung ergriffen und auseinandergefahren worden ist.The tool mounted on the machine can be seen from FIG. 3, one half of which according to FIG. 4 has been gripped by the mounting device and moved apart.

Mit dem Bezugszeichen 1 ist die Kern- und Maskenschießmaschine nach DE-PS 31 48 461 bezeichnet. Auf dem Grundrahmen 9 der Vorrichtung befindet sich der zu betätigende Schlitten 7, der den klappbaren Tisch 6 mit Greifern 5 enthält und auf dem eine oder auch beide Werkzeughälften 3, 4 abgestellt und festgehalten werden können. Die an der Maschine 1 befindlichen Greifer 5 dienen ebenso wie die Greifer am Klapptisch 6 zum Festhalten der jeweiligen Werkzeughälften 3 bzw. 4. Mittels der schwenkbaren Greifarme 8 werden die zusammengefahrenen Werkzeughälften 3, 4 auf der Werkzeugaufnahme 2 festgehalten.The core and mask shooting machine according to DE-PS 31 48 461 is designated by the reference number 1. On the base frame 9 of the device is the slide 7 to be operated, which contains the foldable table 6 with grippers 5 and on which one or both tool halves 3, 4 can be placed and held. The grippers 5 located on the machine 1, like the grippers on the folding table 6, serve to hold the respective tool halves 3 and 4. The pivoted gripper arms 8 hold the tool halves 3, 4 moved together on the tool holder 2.
