Description

Die Erfindung betrifft eine Kernschiessanlage mit den Merkmalen des Oberbegriffs des Patentanspruchs 1 und ein Verfahren zum Austausch einer Filterplatte einer Kernschiessanlage mit den Merkmalen des Oberbegriffs des Patentanspruchs 5.The invention relates to a core shooting range with the features of the preamble of claim 1 and a method for exchanging a filter plate of a core shooting range with the features of the preamble of claim 5.

Eine derartige Kernschiessanlage und ein derartiges Verfahren zum Austausch einer Filterplatte einer Kernschiessanlage ist beispielsweise aus der CN 2 701 552 Y bekannt, die eine Filterwechseleinrichtung mit einer Filterplattenaufnahme beschreibt.Such a core shooting range and such a method for exchanging a filter plate of a core shooting range is known, for example, from US Pat CN 2 701 552 Y known that describes a filter changing device with a filter plate holder.

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 the case of core shooters operating at a relatively high number of cycles of, for example, 40 seconds, in order to maintain sufficient gas permeability, the filter plate mentioned, also referred to as a shooting sieve, has to be exchanged for a cleaned filter plate after every hour, for example. To do this, operating personnel must be available at the appropriate time to remove the dirty, relatively heavy filter plate from lift off the extended fumigation chamber and replace it with a cleaned filter plate. Due to the design height of the machine, this must be done in an unfavorable position for handling. In addition, this takes around 5 minutes each, so that the effective operating time of the core shooting range 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 eine Kernschiessanlage mit den Merkmalen des Patentanspruchs 1. Ausserdem wird hierzu ein Verfahren zum Austausch der Filterplatte (8) der Kernschiessanlage mit den Merkmalen des Patentanspruchs 5 vorgeschlagen.The invention has for its object to simplify the replacement of a dirty filter plate, so that the time and effort involved is reduced and the productivity of the core shooting range is increased accordingly. This object is achieved according to the invention by a core shooting range with the features of claim 1. In addition, a method for replacing the filter plate (8) of the core shooting range with the features of claim 5 is proposed.

Advantageous embodiments of the invention are the subject of the dependent claims and the following description can be found with reference to the drawings. It shows:
  • Fig. 1 2 shows a perspective and schematic representation of a core shooting range according to the invention,
  • Fig. 2 a side view of the core shooting range after Fig. 1 ,
  • Fig. 3 a longitudinal section through the core shooting range Fig.1 and Fig.2 along the line III-III and
  • Fig. 4 Longitudinal sections of the core shooting range 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 system 1 essentially consists of a molding box 2 with an upper and lower molding 3, 4, via which a core shooting chamber 5 or a gassing chamber 6 is brought into position by a transverse movement in accordance with the working cycle of the system. Above this is a sealing hood 9, which can be lowered onto it by means of a pressing unit 7 and is closed at the bottom by a filter plate 8 the hopper 11 has been filled with a sufficient amount of molding sand. In order to harden the molding sand, the core shooting chamber 5 is inserted into its in along a transfer carriage 12 Fig.1 and Fig.3 shown position retracted so that the gassing chamber 6 between the sealing hood 9 and the molding box 2 retracts and gas can flow to the molding box via the gassing pipe 13 provided thereon after sealing the sealing hood.

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, a pivotable plate holder 14 with three fork-shaped plate receptacles 15, 16 and 17 arranged at an angle of preferably 120 ° to one another is provided on the side of the core shooting range 1. A first plate holder 15 is located at the beginning of the exchange of a dirty filter plate 8 in a plane parallel to the transfer carriage 12, so that the filter plate 8 can be transferred to the plate holder 14 or inserted into a plate holder 15 by the movement of the gassing chamber 6 . After the gassing chamber 6 has been moved back into a position above the core box 2, the plate holder can be pivoted, so that the contaminated filter plate 8 moves from its horizontal position into an obliquely downward, easily accessible inclined position by means of a pivoting movement, so that it can be accessed and thus Exchange for a cleaned or new filter plate 8 is facilitated. In addition, this pivoting movement brings a filter plate 8 held in stock in another (17) of the three plate receptacles 15, 16 and 17 into the position in which the soiled filter plate 8 was previously, so that it was immediately taken up again by the core shooting system 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.So 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 swiveling movement about a horizontally directed axis 18 or the resulting steep inclined position, is located at the inner end Each fork-shaped plate receptacle 15, 16 or 17 has a latch 19, 20 or 21. For the execution of the pivoting movement, a suitable rotary drive (not shown) 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 "l" 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 the movement phases to be passed through to replace a filter plate 8 is shown in FIG Fig. 4 illustrated by the representation of the successive positions "a" to "n". Starting from position "a" after position "b", the sealing hood 9 is lowered and the locking device 22 provided on the edge of the filter plate 8 is released. In position "c", the sealing hood 9 was lifted off the filter plate 8 so that it loosely opened the fumigation chamber 6 rests. According to position "d", the gassing chamber 6 with the filter plate 8 lying there has been moved to the left to the plate holder 14, so that the filter plate 8 comes into engagement with the plate holder 15 and latches 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. As a result, the gassing chamber 6 can move back to the position “f” above the core box 2. This enables a pivoting movement of the plate holder 14 in such a way that the soiled filter plate passes through 120 ° into a downward, easily accessible inclined position, as shown in position "g". At the same time, the clean filter plate 8 kept in stock in the plate receptacle 17 pivots into the freed-up horizontal transfer position, in which the gassing chamber 6 can move under the filter plate 8, so that it reaches the position "h". According to Position "i" the gassing chamber 6 moved under the new or cleaned filter plate 8 has been raised so that the filter plate 8 rests on it. The gassing chamber 6 then moves back to the "k" position with the filter plate lying on top. According to position "1", the sealing hood 9 has then been lowered onto the new filter plate 8 and the catch 18 has been brought into engagement between the two. In position "m", the sealing hood 9, together with the new filter plate 8 locked to it, has been raised again for a starting position for a new production cycle. In addition, in this position "m", the dirty filter plate 8 pivoted downward was removed from the plate holder 15 and a new cleaned filter plate 8 was inserted into it. In position "n", the plate holder 14 was pivoted a further 120 ° about its horizontal axis 19, so that the cleaned filter plate 8 reaches the standby 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 goes without saying that the movements of the system components described can be carried out relatively quickly in an automatically controlled manner by means of suitable electrically, pneumatically or hydraulically operated drive elements.
