Description

Querschneider für Platten aus Kunststoff, insbesondere aus Polyurethanschaumstoff Die vorliegende Neuerung richtet sich auf einen Querschneider für Platten aus Kunststoff, insbesondere aus Polyurethanschaumstoff, bestehend aus einem Gestell, auf dem ein Tisch angeordnet ist, der eine Querritze aufweist für ein hindurchragendes Schneidwerkzeug, das in Führungen quer zum Tisch mittels eines Supports hinundherverschiebbar angeordnet ist, und wobei die Fahrbahn des Schneidwerkzeuges von einem Spänekasten umgeben ist, der zu beiden Seiten des Tisches in Je einen Sammeltrichter mündet.Cross cutter for sheets of plastic, in particular of polyurethane foam The present innovation is aimed at a sheeter for sheets made of plastic, in particular made of polyurethane foam, consisting of a frame on which a Table is arranged, which has a transverse gap for a cutting tool protruding through it, which is arranged so that it can be moved back and forth in guides across the table by means of a support is, and wherein the track of the cutting tool is surrounded by a chip box which opens into a collecting funnel on both sides of the table.

Zweck einer derartigen Vorrichtung ist das Schneiden von Platten auf das gewünschte Maß.The purpose of such a device is the cutting of plates the desired measure.

Bei den bekannten Querschneldern für Platten aus Kunststoff ist an dem Spänekasten eine pneumatische Absaugung angeordnet. Es hat sich gezeigt, daß, bedingt durch die vielen Öffnungen, der Wirkungsgrad außerordentlich schlecht war, und daß Infolge der elektrostatischen Aufladung der in mehlartiger Form anfallenden Späne diese sich überall an der Wandung der Spänekastens festsetzten.In the case of the known Querschneldern for plates made of plastic is on A pneumatic suction system is arranged in the chip box. It has been shown that due to the many openings, the efficiency was extremely poor, and that as a result of electrostatic charge of the flour-like Shavings produced in the form of these stuck anywhere on the wall of the shavings box.

Die vorliegende Neuerung hat sich deshalb die Aufgabe gestellt, einen Querschneider zu schaffen, bei dem die Abführung der Späne ohne Störungen gewährleistet ist.The present innovation has therefore set itself the task of creating a To create cross cutter in which the removal of the chips is guaranteed without interference is.

Dies wird neuerungsgemäß dadurch erreicht, daß an dem Support des Schneidwerkzeuges ein Kratzer angeordnet ist. Dadurch wird erreicht, daß bei dem Hinundherfahren des Schneidwerkzeuges bei Jedem Hub das Spänematerial entweder rechts oder links in die Sammeltrichter geschoben wird. Vorzugsweise besteht der Kratzer aus zwei Blättern, die beiderseits des Schneidwerkzeuges angeordnet sind. Das Schneidwerkzeug besteht in der Regel aus einem scheibenförmigen Sägeblatt, das zwischen den beiden Blättern des Kratzers vorgesehen ist.This is achieved according to the innovation that on the support of the Cutting tool is arranged a scratch. This ensures that the The cutting tool moves back and forth with each stroke, the chip material either on the right or is pushed into the collecting funnel on the left. Preferably the scratch is there from two sheets, which are arranged on both sides of the cutting tool. The cutting tool Usually consists of a disc-shaped saw blade that sits between the two Scrolling the scratch is provided.

Nach einer besonderen Ausführungsform der Neuerung mündet der Spänekasten von oben in die Sammeltrichter,und der Spänekasten sowie die Führungen des Supports überlappen die Sammeltrichter soweit, daß beide Blätter des Kratzers sich in den Umkehrstellungen Jeweils über den Sammeltrichtern befinden. Auf diese Weise wird erreicht, daß sämtliches Material, was von den beiden Blättern des Kratzers vor sich hergeschoben wird, in die Sammeltrichter hineingelangt.According to a special embodiment of the innovation, the chip box opens from above into the collecting funnel and the chip box as well as the guides of the support overlap the collecting funnel so far that both sheets of the scratch are in the Reversal positions are in each case above the collecting funnels. That way will achieved that all material what from the two blades of the scratch is in front is pushed into the collecting funnel.

Nach einer weiteren besonderen Aus führungs form sind die Sammeltrichter mit einer pneumatischen Absaugung versehen und eine das Schneidwerkzeug tragende und im Support gelagerte Welle ist durch einen Schlitz in der Wandung des Spänekratzers hindurchgeführt und dieser Schlitz ist zu beiden Seiten der Welle abdichtbar. Auf diese Weise wird ein besonders guter Wirkungseffekt des Absauggebläses erreicht, da relativ wenig Falschluft angesaugt wird.The collecting hoppers are another special design provided with a pneumatic suction and one that carries the cutting tool and the shaft mounted in the support is through a slot in the wall of the chip scraper passed through and this slot can be sealed on both sides of the shaft. on this way the extractor fan has a particularly good effect achieved, since relatively little false air is sucked in.

Die Abdichtung des Schlitzes besteht vorzugsweise aus einem elastischen Band, das im Bereich der Enden des Schlitzes befestigt ist und mittels am Support gelagerter Führungsrollen um den Support herumgeführt ist. Beim Hinundherfahren wird also das Band im Bereich des Supports bzw. des Schneidwerkzeuges vom Spänekasten abgehoben, um dahinter wieder mittels der Führungsrollen angelegt zu werden.The sealing of the slot preferably consists of an elastic one Tape that is attached in the area of the ends of the slot and by means of the support stored guide rollers is guided around the support. When driving back and forth So the tape in the area of the support or the cutting tool is removed from the chip box lifted off in order to be put on again behind it by means of the guide rollers.
