Description

Die Erfindung betrifft ein Verfahren zum Austausch einer Filterplatte einer Kernschiessanlage, die den unteren Abschluss einer Dichthaube bildet, unter die, entsprechend den Verfahrensstufen des Kernschiessens, abwechselnd eine Begasungskammer und eine Kernschiesskammer einführbar ist, mit Lösen einer Arretierung zwischen der Dichthaube und de Filterplatte, Abheben der Dichthaube von einer verschmutzten Filterplatte, seitliches Herausbewegen der Begasungskammer mit aufliegende Filterplatte aus der Kernschiessanlage, Austauschen der verschmutzten Filterplatte gegen eine gereinigte Filterplatte, Zurückbewegen der Begasungskammer mit aufliegender, gereinigter Filterplatte in die Kernschiessanlage, Absenken der Dichthaube und Arretieren der gereinigten Filterplatte an der Dichthaube.The invention relates to a method for replacing a filter plate of a core shooting system, which forms the lower end of a sealing hood, under which, according to the process stages of core shooting, a gassing chamber and a core shooting chamber is inserted, with releasing a lock between the sealing cap and de filter plate, lifting the sealing hood of a dirty filter plate, lateral moving out of the gassing with overlying filter plate from the core shooting system, replacing the dirty filter plate against a cleaned filter plate, moving back the gassing with resting, cleaned filter plate in the core shooting system, lowering the sealing cap and locking the cleaned filter plate to the sealing cap ,

Ausserdem betrifft die Erfindung eine Kernschiessmaschine mit den Merkmalen des Oberbegriffs des Patentanspruchs 2.Moreover, the invention relates to a core shooting machine having the features of the preamble of patent claim 2.

Bei solchen mit verhältnismässig hoher Taktzahl von z.B. 40 Sekunden arbeitenden Kernschiessmaschinen muss für die Aufrechterhaltung einer ausreichenden Gasdurchlässigkeit die genannte, auch als Schiesssieb bezeichnete Filterplatte z.B. nach jeweils einer Stunde gegen eine gereinigte Filterplatte ausgetauscht werden. Hierzu muss zu gegebener Zeit jeweils Bedienpersonal bereit stehen, um die verschmutzte, verhältnismässig schwere Filterplatte von der ausgefahrenen Begasungskammer abzuheben und durch eine gesäuberte Filterplatte zu ersetzen. Aufgrund der konstruktionsmässig vorgegebenen Höhe der Maschine muss dies in einer für die Handhabung ungünstigen Position erfolgen. Ausserdem ist dies mit einem Zeitaufwand von jeweils ca. 5 Minuten verbunden, so dass die effektive Betriebszeit der Kernschiessanlage entsprechend begrenzt ist.In such with a relatively high number of cycles of eg 40 seconds working core shooting machines must be replaced for maintaining a sufficient gas permeability said, also referred to as Schiesssieb filter plate, for example, after every hour against a cleaned filter plate. For this purpose, in each case operating personnel must be available to the polluted, relatively heavy filter plate of lift off the extended gassing chamber and replace it with a cleaned filter plate. Due to the design-defined height of the machine this must be done in an unfavorable position for handling. In addition, this is associated with a time of about 5 minutes, so that the effective operating time of the core shooting system is limited accordingly.

Der Erfindung liegt die Aufgabe zugrunde, das Austauschen einer verschmutzten Filterplatte zu vereinfachen, so dass der dabei anfallende Zeit- und Arbeitsaufwand verringert wird und die Produktivität der Kernschiessanlage entsprechend erhöht wird. Die Lösung dieser Aufgabe erfolgt erfindungsgemäss durch ein Verfahren mit den Merkmalen des Patentanspruchs 1. Ausserdem wird hierzu eine Kernschiessanlage mit den Merkmalen des Patentanspruchs 2 vorgeschlagen.The invention has for its object to simplify the replacement of a dirty filter plate, so that the time and labor required thereby is reduced and the productivity of the core shooting system is increased accordingly. The solution of this object is achieved according to the invention by a method having the features of claim 1. In addition, this is proposed a core shooting system with the features of claim 2.

Advantageous embodiments of the invention are set forth in the dependent claims and the following description with reference to the drawings. It shows:
  • Fig.1 a perspective and schematic representation of an inventive core shooting facility,
  • Fig.2 a side view of the core shooting after Fig.1 .
  • Figure 3 a longitudinal section through the core shooting after Fig.1 and Fig.2 along the line III-III and
  • Figure 4 Longitudinal sections of the core shooting facility Fig.1 to Fig.3 with successive movement phases "a" to "n" of components of this system when replacing a dirty filter plate.

Die Kernschiessanlage 1 besteht zum Wesentlichen aus einem Formkasten 2 mit oberem und unterem Formteil 3,4, über den durch eine Querbewegung entsprechend dem Arbeitstakt der Anlage, entweder eine Kernschiesskammer 5 oder eine Begasungskammer 6 in Position gebracht wird. Über diesen befindet sich eine mittels einer Presseinheit 7 dichtend auf sie absenkbare, nach unten durch eine Filterplatte 8 geschlossene Dichthaube 9. Ein in die Dichthaube 9 einmündendes Pressluftrohr 10 dient der Beaufschlagung der Kernschiesskammer 5 zum Einschiessen von Kernsand in den Formkasten 2, der zuvor über den Trichter 11 mit einer ausreichenden Menge von Formsand gefüllt worden ist. Zum Aushärten des Formsandes wird die Kernschiesskammer 5 entlang eines Transferschlittens 12 in ihre in Fig.1 und Fig.3 gezeigte Position zurückgefahren, so dass die Begasungskammer 6 zwischen die Dichthaube 9 und den Formkasten 2 einfährt und nach dichtendem Aufsetzen der Dichthaube 9 Gas über das an ihr vorgesehene Begasungsrohr 13 dem Formkasten zuströmen kann.The core shooting installation 1 consists essentially of a molding box 2 with upper and lower mold part 3, 4, via which either a core shooting chamber 5 or a gassing chamber 6 is brought into position by a transverse movement corresponding to the working cycle of the installation. About this is a sealing means of a press unit 7 sealingly lowered onto it, down through a filter plate 8 closed sealing hood 9. A in the sealing hood 9 opening compressed air tube 10 serves to pressurize the core shooting chamber 5 for injection of core sand into the molding box 2, previously on the hopper 11 has been filled with a sufficient amount of molding sand. To harden the molding sand, the core shooting chamber 5 along a transfer carriage 12 in their in Fig.1 and Fig.3 zurückgefahren shown position so that the Begasungskammer 6 enters between the sealing hood 9 and the molding box 2 and after sealing placing the sealing cap 9 gas can flow over the provided at her gassing tube 13 the molding box.

Für ein Zeit und Arbeitsaufwand sparendes Auswechseln der Filterplatte 8 nach Erreichen eines bestimmten Verschmutzungsgrades ist seitlich an der Kernschiessanlage 1 eine schwenkbare Plattenhalterung 14 mit drei im Winkel von vorzugsweise jeweils 120° zueinander angeordneten, gabelförmigen Plattenaufnahmen 15, 16 und 17 vorgesehen. Dabei befindet sich eine erste Plattenaufnahme 15 zu Beginn des Austausches einer verschmutzten Filterplatte 8 in einer zum Transferschlitten 12 parallelen Ebene, so dass die Übergabe der Filterplatte 8 an die Plattenhalterung 14 bzw. das Einschieben in eine Plattenaufnahme 15 durch die Fahrbewegung der Begasungskammer 6 erfolgen kann. Nach Zurückbewegung der Begasungskammer 6 in eine Position oberhalb des Kernkastens 2 ist die Plattenhalterung schwenkbar, so dass durch eine Schwenkbewegung die verschmutzte Filterplatte 8 aus ihrer horizontalen Lage in eine schräg nach unten gerichtete, zugriffsgünstige Schräglage gelangt, so dass ein Zugriff zu ihr und damit ein Austausch gegen eine gereinigte oder neue Filterplatte 8 erleichtert wird. Ausserdem gelangt durch diese Schwenkbewegung eine auf Vorrat in einer anderen (17) der drei Plattenaufnahmen 15, 16 und 17 auf Vorrat gehaltene Filterplatte 8 in die Position, in der sich zuvor die verschmutze Filterplatte 8 befand, so dass diese sofort neu von der Kernschiessanlage aufgenommen werden kann.For a time and labor-saving replacement of the filter plate 8 after reaching a certain degree of contamination is laterally provided on the core shooting 1 a pivotable plate holder 14 with three at an angle of preferably 120 ° to each other, fork-shaped plate receivers 15, 16 and 17. In this case, there is a first plate holder 15 at the beginning of the exchange of a dirty filter plate 8 in a direction parallel to the transfer carriage 12 level, so that the transfer of the filter plate 8 to the plate holder 14 and the insertion into a disc holder 15 by the driving movement of the Begasungskammer 6 can take place , After moving back the gassing chamber 6 in a position above the core box 2, the plate holder is pivotable, so that passes through a pivoting movement, the soiled filter plate 8 from its horizontal position in an obliquely downwardly directed, easy access inclined position, so that access to it and thus a Exchange against a cleaned or new filter plate 8 is facilitated. In addition, passes through this pivotal movement in stock in another (17) of the three plate receptacles 15, 16 and 17 held in stock filter plate 8 in the position in which previously the soiled filter plate 8 was, so that they were immediately re-absorbed by the core shooting facility can be.

Damit eine in eine Plattenaufnahme 15, 16 oder 17 eingeschobene Filterplatte 8 durch die um eine horizontal gerichtete Achse 18 erfolgende Schwenkbewegung bzw. durch die sich dabei ergebende steile Schräglage nicht aus der Plattenaufnahme 15, 16 oder 17 herausfällt, befindet sich am inneren Ende jeder gabelförmigen Plattenaufnahme 15, 16 oder 17 jeweils eine Rastklinke 19, 20 oder 21. Für die Ausführung der Schwenkbewegung ist an der Antriebswelle 23 der schwenkbaren Plattenhalterung 14 ein nicht dargestellter, geeigneter Drehantrieb angekoppelt.In order that a filter plate 8 inserted into a plate receptacle 15, 16 or 17 does not fall out of the plate receptacle 15, 16 or 17 due to the pivoting movement taking place about a horizontally directed axis 18 or due to the resulting steep inclined position, is located at the inner end each fork-shaped plate holder 15, 16 or 17 each have a latch 19, 20 or 21. For the execution of the pivoting movement, a not shown, suitable rotary drive is coupled to the drive shaft 23 of the pivotable plate holder 14.

Der Ablauf der zum Austausch einer Filterplatte 8 zu durchlaufenden Bewegungsphasen ist in Fig. 4 durch die Darstellung der hierbei aufeinander folgenden Positionen "a" bis "n" veranschaulicht. Ausgehend von der Position "a" erfolgt nach Position "b" ein Absenken der Dichthaube 9 und Lösen der am Rand der Filterplatte 8 vorgesehenen Arretierung 22. In Position "c" wurde die Dichthaube 9 von der Filterplatte 8 abgehoben, so dass sie lose auf der Begasungskammer 6 aufliegt. Gemäss Position "d" ist die Begasungskammer 6 mit aufliegender Filterplatte 8 nach links zu der Plattenhalterung 14 gefahren, so dass die Filterplatte 8 in Eingriff mit der Plattenaufnahme 15 gelangt und dort mit der Klinke 19 verrastet. Nach Position "e" hat sich die Begasungskammer 6 abgesenkt, so dass sie den Kontakt mit der Filterplatte 8 verloren hat. Folglich kann sich die Begasungskammer 6 in die Position nach "f" oberhalb des Kernkastens 2 zurückbewegen. Dies ermöglicht eine Schwenkbewegung der Plattenhalterung 14 derart, dass die verschmutzte Filterplatte um 120° in eine nach unten gerichtete, zugriffsgünstige Schräglage gelangt, wie sie in Position "g" dargestellt ist. Gleichzeitig schwenkt dabei die in der Plattenaufnahme 17 auf Vorrat gehaltene saubere Filterplatte 8 in die freigewordene horizontale Übergabeposition, in der die Begasungskammer 6 unter die Filterplatte 8 einfahren kann, so dass sie die Position "h" erreicht. Gemäss Position "i" ist die unter die neue, bzw. gereinigte Filterplatte 8 eingefahrene Begasungskammer 6 angehoben worden, so dass die Filterplatte 8 auf ihr aufliegt. Anschliessend fährt die Begasungskammer 6 mit aufliegender Filterplatte in die Position "k" zurück. Gemäss Position "I" hat sich anschliessend die Dichthaube 9 auf die neue Filterplatte 8 abgesenkt und zwischen beiden wurde die Arretierung 18 in Eingriff gebracht. In Position "m" hat sich die Dichthaube 9 zusammen mit der an ihr arretierten neuen Filterplatte 8 für eine Ausgangsposition zu einem neuen Produktionstakt wieder angehoben. Ausserdem wurde in dieser Position "m" die nach unten geschwenkte, verschmutzte Filterplatte 8 aus der Plattenaufnahme 15 entfernt und eine neue gereinigte Filterplatte 8 in sie eingeschoben. In Position "n" wurde die Plattenhalterung 14 um weitere 120° um ihre horizontale Achse 19 geschwenkt, so dass die gereinigte Filterplatte 8 in die Bereitschaftsposition entsprechend Position "a" gelangt.The sequence of to be traversed for the exchange of a filter plate 8 movement phases is in Fig. 4 illustrated by the representation of the successive positions "a" to "n". Starting from the position "a" takes place after position "b" lowering the sealing cap 9 and release the provided on the edge of the filter plate 8 lock 22. In position "c" the sealing cap 9 was lifted from the filter plate 8 so that they loose the gassing chamber 6 rests. According to position "d", the gassing chamber 6 with the filter plate 8 lying on it has moved to the left towards the plate holder 14, so that the filter plate 8 comes into engagement with the plate holder 15 and locks there with the pawl 19. After position "e", the gassing chamber 6 has lowered so that it has lost contact with the filter plate 8. Consequently, the gassing chamber 6 can move back to the position after "f" above the core box 2. This allows a pivotal movement of the plate holder 14 such that the soiled filter plate passes by 120 ° in a downwardly directed, easy access inclined position, as shown in position "g". At the same time, the clean filter plate 8 kept in stock in the disk holder 17 pivots into the released horizontal transfer position, in which the gassing chamber 6 can enter under the filter plate 8, so that it reaches the position "h". According to Position "i" has been brought under the new, or cleaned filter plate 8 retracted gassing 6, so that the filter plate 8 rests on her. Subsequently, the gassing chamber 6 moves back to the position "k" with the filter plate resting thereon. According to position "I", the sealing hood 9 has subsequently lowered onto the new filter plate 8 and the lock 18 has been brought into engagement between the two. In position "m", the sealing cap 9 has lifted together with the new filter plate 8 locked on it for a starting position to a new production cycle again. In addition, in this position "m", the downwardly tilted, dirty filter plate 8 was removed from the plate holder 15 and a new cleaned filter plate 8 inserted into it. In position "n", the plate holder 14 has been pivoted about a further 120 ° about its horizontal axis 19, so that the cleaned filter plate 8 reaches the ready position corresponding to position "a".

Es versteht sich, dass die Bewegungen der beschriebenen Anlagekomponenten automatisch gesteuert durch geeignete elektrisch, pneumatisch oder hydraulisch betriebene Antriebselemente relativ schnell ausgeführt werden kann.It is understood that the movements of the described system components can be performed relatively quickly controlled by suitable electrically, pneumatically or hydraulically operated drive elements.
