Description
Die Erfindung betrifft eine Bandschleifmaschine zum Feinschleifen, insbesondere Feinstschleifen großflächiger plattenförmiger Werkstücke mit mindestens zwei hintereinander angeordneten Bandschleifaggregaten.The invention relates to a belt grinding machine for fine grinding, in particular fine grinding of large areas Plate-shaped workpieces with at least two belt sanding units arranged one behind the other.
Bandschleifmaschinen dieser Art gehören seit langem zum allgemein bekannten Stand tür Technik. Das beim Fein- und Feinstschleifen großflächiger furnierter, lackierter oder sonstwie beschk .teter oder auch massiver Werkstücke heute bevorzugt angewandte Kreuzschleifverfahren lassen diese Maschinen indes nur insoweit zu, als das Werkstück nach einer 90° -Schwenkung die Maschine nochmals oder eine zweite Bandschleifmaschine durchläuft Dies ist jedoch unwirtschaftlich und technologisch umständlich, weil mit Rücksicht auf die normalerweise automatisierte Fertigung zusätzlich eine sogenannte Winkelübergabevorrichtung benötigt wird und bei Verwendung mehrerer Maschinen auch ein entsprechend großer Platzbedarf entstehtBelt grinders of this type have long been part of the well-known prior art. That at Fine and ultra-fine grinding of large-area veneered, lacquered or otherwise coated or even For massive workpieces, however, these machines only allow cross-grinding processes that are preferred today to the extent that the workpiece after a 90 ° swivel, the machine again or a second However, this is uneconomical and technologically cumbersome because with In consideration of the normally automated production, there is also a so-called angle transfer device is required and when using several machines also a correspondingly large space requirement arises
Der Erfindung liegt daher die Aufgabe zugrunde, eine weiterentwickelte und verbesserte Bandschleifmaschine zu schaffen, mit der die Werkstücke im Kreuzschleifverfahren bearbeitet werden können, ohne daß es dazu einer Wendeeinrichtung tung bedarf.The invention is therefore based on the object of a further developed and improved belt grinding machine to create, with which the workpieces can be processed in the cross grinding process without it a turning device is required.
Die gestellte Aufgabe ist erfindungsgemäß dadurch gelöst, daß das erste oder bei Vorhandensein von mehr als zwei Bändschleifaggregaten das erste und das zweite Bandschleifaggregat als ein Langbandschleifaggregat mit quer zur Vorschubrichtung des Werkstückes umlaufendem Schleifband ausgebildet ist.The object is achieved according to the invention in that the first or in the presence of more as two belt sanding units the first and the second belt sanding unit as one long belt sanding unit is designed with a grinding belt rotating transversely to the feed direction of the workpiece.
Dabei ist es vorteilhaft, wenn die Langbandschleifaggregate mit einem elastischen Druckbalken und einem zwischen dem Schleifband und dem Druckbalken eingeschalteten, endlos umlaufenden Drucklammellenband ausgerüstet sind.It is advantageous if the long belt sanding units with an elastic pressure beam and a between the sanding belt and the pressure beam connected, endlessly rotating pressure lamellar belt are equipped.
Bei einer solchen erfindungsgemäOen Bandschleifmaschine braucht das Werkstück nicht mehr gewendet zu werden, sondern durchläuft die Schleifmaschine in gleichbleibender Richtung und es werden auch nicht mehrere Maschinen benötigtIn such a belt grinder according to the invention the workpiece no longer needs to be turned, but goes through the grinding machine in in the same direction and multiple machines are not required
