Description

Förderband für Guß und Altsand Gegenstand der vorliegenden Erfindung ist ein Förderband für Gießereien, dessen oberer Strang in der einen Richtung den Guß zur Putzerei und dessen unterer Strang in der entgegengesetzten Richtung den Altsand zur Sandaufbereitung fördern soll.Conveyor belt for casting and used sand is the subject of the present invention is a conveyor belt for foundries, the upper strand of which runs in one direction Cast to the cleaning shop and its lower strand in the opposite direction Is to promote used sand for sand processing.

Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in den Abb. i und a im Längs- bzw. Querschnittdargestellt. Das Förderband besteht aus einzelnen Wagen w, die je auf vier Rollen laufen und oben mit Rosten abgedeckt sind. An der unteren Seite eines jeden Wagens sind beliebig viele, beispielsweise zwei Bleche b, gelenkig befestigt, die frei herabhängen, wenn der Wägen auf dem oberen Strange des Brandes läuft, sich dagegen beim Übergang des Wagens auf den unteren Strang umlegen, sich dabei dachziegelförmig überdecken und somit ein zusammenhängendes Band bilden.The drawing shows an embodiment of the subject matter of the invention shown in Figs. i and a in longitudinal and cross-section. The conveyor belt exists from individual wagons, each running on four rollers and covered with grates at the top are. At the bottom of each car there are any number, for example two metal sheets b, hingedly attached, which hang freely when the trolley is on the The upper strand of the fire is running, but when the car passes over to the fold down the lower strand, covering each other in the shape of a roof tile and thus a coherent one Form a band.

Die einzelnen Wagen stehen mit seitlichen, endlosen Treibketten k in Verbindung, und zwar derart, daß Mitnehmerbolzen der Ketten mit ihren Zapfen z (Abb. 3) hinter entsprechend an den Wagen w befestigte Halter h greifen und so den Wagen vorwärts bewegen. In vorliegendem Falle ist jeder zweite Gelenkbolzen der Kette als Mitnehmerbolzen ausgebildet. Deswegen verringert sich die Entfernung je zweier benachbarter Mitnehmerbolzen z an den Umlenkstellen, welche die Ketten in Formen von Kreisbogen durchlaufen. Die Halter h an den Wagen sind nun so bemessen (vgl. Abb.3), daß die Mitnehmerbolzen an den Umlenkstationen jeden Wagen gegen Herausfallen sichern. Dagegen ist es auf dem geraden oberen Teil des Förderbandes ohne weiteres möglich, die Wagen von den Mitnehmerbolzen z abzuheben.The individual carriages are connected to lateral, endless drive chains k in such a way that drive pins of the chains with their pins z (Fig. 3) grip behind holders h attached to the carriage w and thus move the carriage forward. In the present case, every second hinge pin of the chain is designed as a driving pin. Because of this, the distance between two adjacent driving pins z is reduced at the deflection points through which the chains run in the form of circular arcs. The holders h on the carriages are now dimensioned in such a way (see Fig. 3) that the driving pins at the deflection stations secure each carriage against falling out. On the other hand, on the straight upper part of the conveyor belt, it is easily possible to lift the car off the driving pin z.

An den Umlenkstellen muß dafür gesorgt werden, daß .die im Sinne der Fahrtrichtung sich zuletzt umlegenden Bleche b nicht infolge ihrer Schwere aus dem Umlenkkreisbogen herausfallen und die lückenlose Verbindung dieser Bleche mit den ersten Blechen des folgenden Wagens sowie die dachziegelförmige Überdeckung beider stets gewährleistet wird. Zu diesem Zweck dienen Querverbindungenq, beispielsweise Flacheisen, die hinter jedem Wagen w die einander gegenüberliegenden Glieder der beiden seitlichen Treibketten k miteinander verbinden. Gegen diese Flacheisen q legen sich die Bleche b, so daß sie an den Umlenkstellen richtig geführt werden.At the deflection points it must be ensured that the sheets b that are last folded in the direction of travel do not fall out of the arc of the deflection due to their gravity and that the seamless connection of these sheets with the first sheets of the following car as well as the roof tile-shaped overlap of both is always guaranteed. For this purpose, cross connections q, for example flat bars, which connect the opposing links of the two lateral drive chains k to one another behind each carriage w. The metal sheets b lie against this flat iron q so that they are correctly guided at the deflection points.

Wenn über den Förderwagen abgegossene Formkasten ausgeleert werden, so bleiben die Gußstücke auf .den Rosten des oberen Förderbandstranges - liegen und werden in der in Abb. i durch Pfeil gekennzeichneten Richtung befördert, während der durch die Roste fallende Altsand auf dem unteren Strange, wo die umgelegten Bleche b ein zusammenhängendes Transportband bilden, in entgegengesetzter Richtung zur Sandaufbereitung wandert.If molding boxes that have been poured off via the trolley are emptied, so the cast pieces remain on .the grates of the upper conveyor belt strand - lie and are conveyed in the direction indicated by the arrow in Fig. i, while the used sand falling through the grids on the lower strand, where the turned over Sheet metal b form a coherent conveyor belt, in the opposite direction migrates to sand processing.
