Abstract

In a foundry, the runners and risers etc., circulate continuously for remelting with fresh material; and the invention uses hydraulic cylinders (HC) with piston driven towards each other so no expensive anvils are required. In the embodiment, four HC's are located at 90 degrees to each other so the returned scrap can be pressed into packets or bundles with a cross-section are matching the size of the inlet to the melting furnace. Above and/or beneath the HC are cutting shears or flame cutting burners so packets with a desired height can be obtd. The overall result is a simple method of bundling scrap which minimises the use of manual labour; the HC can exert a force of several thousand tonnes on the scrap.

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

'Vorrichtung zur Paketierung von Kreislaufmaterial in GieP;ereien' Es ist bekannt, daß der Anschnitt und das Kreislaufmaterial ohne Vor zerkleinerung nicht wieder in den Schmelzproze (Schmelzofen) zurückgeführt werden können.'Device for the packaging of recycled material in GieP; erei' It is known that the gate and the circulating material without before comminution cannot be returned to the melting process (melting furnace).

In der Regel wird dieses Material von Hand verlesen und einzeln entsprechend transportiert und zerkleinert.As a rule, this material is selected by hand and individually accordingly transported and shredded.

Um diesen manuellen Vorgang wesentlich zu vereinfachen, wird erfindungsgemäß folgende Vorrichtung vorgeschlagen.In order to significantly simplify this manual process, the invention proposed the following device.

In der Abb. (a) ist dargestellt mit 1), 2), 3) und 4) vier gegenläufig arbeitende flydraulikzylinder.In Fig. (A) is shown with 1), 2), 3) and 4) four in opposite directions working flydraulic cylinders.

Der Freiraum 5) wird individuell der Gißofenöffnung vorgegeben. Das zu paketierende Material wird über eine Fördervorrichtung dieser Freifläche 5) zugeführt und hier durch vier gegenläufig aufeinander zulaufende Kräfte paketiert.The free space 5) is specified individually for the casting furnace opening. That Material to be packaged is fed to this open space 5) via a conveyor device and here packaged by four forces converging in opposite directions.

Diese erfindungsgemäße Vorrichtung hat den Vorteil, daß keine teuren Gegenlager geschaffen werden müssen Teilweise sind mehrere Tausend Tonnen gegenläufige Kraft aufzuwenden.This device according to the invention has the advantage that no expensive Counter bearings have to be created Sometimes several thousand tons are counter-rotating To use strength.

Damit diese paketierten Blöcke keine unerwünschten ;berlngen erhalten, wird weiterhin erfindungsgemäß vorgeschlagen, oberhalb von der Paketierung einen Schneid- oder Brennvorgang 6) einzuleiten.So that these packetized blocks do not receive any undesired excess lengths, is further proposed according to the invention, above the packaging a Initiate cutting or burning process 6).

Nach der Paketierung wird durch Öffnen der Systeme 1) - 4) das Paket über eine Transportvorrichtung oder in einem Behälter abgefördert.After packaging, opening systems 1) - 4) create the package conveyed away via a transport device or in a container.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten Ausführungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, Kreislaufmaterial so zu paketieren, daß gegenläufige Hydrauliksysteme die Paketierung vornehmen, ohne daß Gegenlager notwendig sind, wobei wunschgerecht die Größe der Paketierung einstellbar ist und die Höhe der Paketierung durch Schneid- oder Brennapparate auf das entsprechende Maß begrenzt werden.Of course, the invention is not limited to the above in detail Embodiments shown are limited, but there are numerous modifications possible, but without deviating from the basic idea, of recycling material in this way package that counter-rotating hydraulic systems carry out the package without Counter bearings are necessary, with the size of the packaging being adjustable as required and the amount of packaging by cutting or burning devices to the corresponding Measure to be limited.
