Description

Vorzerklein.Erer für Altpapier Das Einfüllen von Altpapier in die Kollergänge geschieht heute noch allgemein mit der Hand von den bedienenden Arbeitern, die zwar angewiesen sind, die groben Verunreinigungen zu entfernen, durch deren oft mangelnde Zuverlässigkeit der Erfolg jedoch in Frage gestellt ist. Diese Handarbeit zu ersetzen, die Fremdkörper selbsttätig auszuscheiden und durch Vorzerkleinern die Leistung der Kollergänge zu erhöhen, soll durch den neuen Vorzerkleinerer bewirkt werden.Pre-shredding.Erer for waste paper The filling of waste paper into the Milling is still generally done by hand by the serving workers today, who are instructed to remove the coarse impurities by their however, often lack of reliability of success is in question. This handicraft to replace, to separate out the foreign bodies automatically and by pre-shredding The aim of the new pre-shredder is to increase the performance of the pan mills will.

Der Vorzerkleinerer, in Abb. i im Querschnitt und in Abb. z in der Seitenansicht dargestellt, besteht aus den Ständern i, zwischen denen der Kasten 2 mit anschließender Rinne .3 angebracht ist. Über die Kettenräder q. bewegt sich ein endloses Messerband 5, 6. Die Platte 7 dient zur Aufnahme des Papierballens und wird durch Ketten oder Drahtseile, welche über die Leitrollen 8 nach der Hubwelle 9 geführt werden, nach oben gefördert. Im Innern der Rinne 3 sind federnde, messerartige Zinken i i angebracht, während am Ende der Rinne ein Luftbeweger io angebracht ist.The pre-shredder, in Fig. I in cross section and in Fig. Z in the Side view shown consists of the uprights i, between which the box 2 with an adjoining channel .3 is attached. Via the chain wheels q. is moving an endless knife band 5, 6. The plate 7 is used to receive the bale of paper and is by chains or wire ropes, which over the guide rollers 8 after the lifting shaft 9 are led, promoted upwards. Inside the channel 3 are resilient, knife-like Prongs i i attached, while an air mover io is attached to the end of the gutter.

Arbeitsweise des VorzerkleineTers Nachdem ein Ballen Altpapier auf die Platte 7 gebracht ist, wird das Hubwerk 8, 9 und das umlaufende endlose Messerband 5, 6 in Tätigkeit gesetzt. Das Hubwerk führt den Papierballen dem endlosen umlaufenden Messerband gleichmäßig zu. Dieses nimmt das Papier von dem Ballen ab und zieht dasselbe beim X#orwärtsbewegen über messerartige, federnde Zinken i i. Hierbei wird das Papier zerkleinert und dann weiter durch die Rinne 3 gefördert. Die federnde Anordnung der messerartigen Zinken erfolgt deshalb, damit diese den festen Fremdkörpern ausweicben können. Ist das vorzerkleinerte Papier am Ende der Rinne 3 angelangt, dann erfolgt die Trennung von den beigefügten Fremdkörpern. Die Trennung geschieht in der Weise, daß das aus der Rinne 3 fallende Papier in den Luftstrom eines Luftbewegers i o gerät, welcher das leichte Papier in den Kollergang bläst, während die spezifisch schweren Fremdkörper nach unten außerhalb des Kollerganges fallen. Ist die Platte 7 in ihre höchste Stellung gelangt und der ganze Papierballen dem Kollergang auf die beschriebene Weise zugeführt worden, so wird die Platte wieder in ihre tiefste Stellung gebracht und ein neuer Papierballen aufgelegt. Der Arbeitsvorgang wiederholt sich alsdann in der vorbeschriebenen Weise.How the pre-shredder works After a bale of waste paper the plate 7 is brought, the lifting mechanism 8, 9 and the rotating endless knife band 5, 6 put into action. The lifting mechanism guides the paper bale to the endless circulating one Knife tape closed evenly. This takes the paper off the bale and pulls the same when moving X # forwards over knife-like, springy prongs i i. This is where the paper crushed and then further promoted through the channel 3. The resilient arrangement the knife-like prongs are made so that they dig out the solid foreign bodies can. If the pre-shredded paper has reached the end of the channel 3, then it takes place the separation of the attached foreign bodies. The separation happens in the way that the falling from the channel 3 paper in the air flow of an air mover i o device, which blows the light paper into the pan, while the specific heavy foreign bodies fall down outside of the pan mill. Is the plate 7 reaches its highest position and the whole bale of paper on the pan mill has been fed in the manner described, the plate is back to its deepest Positioned and placed a new bale of paper. The process repeats then in the manner described above.
