Bandschleifmaschinen dieser Art gehören seit langem zum allgemein bekannten Stand der Technik. Das beim Fein- und Feinstschleifen großf'ächiger furnierter, lackierter oder sonstwie beschichteter 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 entsteht.Belt grinding machines of this type have long been part of the generally known state of the art. That at Fine and very fine grinding of large-area veneered, lacquered or otherwise coated or also 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 Belt grinder passes through. 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, 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 lung 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 Bandschleifaggregaten 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 erfindungsgemäßen 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 runs through the grinding machine in the same direction and it won't several machines are required
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. Es zeigtAn exemplary embodiment of the invention is explained in more detail below with reference to the drawing. It shows
Fig. 1 eine Seitenansicht der erfindungsgemäßen ίο Bandschleifmaschine in schematischer Darstellung und Fig. 2 den Schnitt 1-1 aus F ig. 1.Fig. 1 is a side view of the ίο belt grinder according to the invention in a schematic representation and Fig. 2 the section 1-1 from F ig. 1.
In dem im wesentlichen aus zwei parallel nebeneinander angeordneten und über Verbindungsschienen 13 und 14 verbundenen Ständern 11 und 12 bestehenden Bett der Bandschleifmaschine 16 läuft um eine Umkehrrolle 15a und eine Antriebsrolle 156 ein Transportband 15 für den Werkstückvorschub endlos um. Der Antrieb des Transportbandes 15 erfolgt durch einen nicht dargestellten Vorschubmotor über ein stufenlos regelbares Getriebe.In the essentially composed of two parallel juxtaposed and via connecting rails 13 and 14 connected columns 11 and 12 existing bed of the belt grinding machine 16 runs around a Reversing roller 15a and a drive roller 156, a conveyor belt 15 for feeding the workpiece endlessly around. The conveyor belt 15 is driven by a feed motor, not shown, via a continuously variable transmission.
Des weiteren ist auf dem Bett zwischen den Ständern ii und 12 eine obere Verbindungsschiene 16 befestigt, an der im Abstand voneinander zwei Langbandschleifaggregate 17 und 18 angeordnet sind, welche mit einem quer zur Vorschubrichtung des Werkstückes 52a umlaufenden Schleifband ausgestattet sind. Die beiden Langbandschleifaggregate 17, 18 besitzen je einen elastischen Druckbalken und ein zwischen dem Schleifband und dem Druckbalken eingeschaltetes, endlos umlaufendes Drucklamellenband. Jedem der beiden Druckbalken sind in Vorschubrichtung gesehen davor und dahinter Andruckwalzen oder -rollen 19, 20 bzw. 21, 22 zugeordnet. Mit den Andruckwalzen oder -rollen 19 bzw. 2! liegt in einer Ebene jeweils eine Kontaktrolle, die vom durchlaufenden Werkstück 52a betätigt wird und die Ab- und Aufwärtsbewegungen der zugeordneten Druckbalken steuert. Die Druckbalken sind mit - nicht dargestellten - Einrichtungen versehen, mit denen die Arbeitsbreite entsprechend der Breite der durchlaufenden Werkstücke 52a eingestellt werden kann. Furthermore, an upper connecting rail 16 is attached to the bed between the uprights ii and 12, on which two long belt sanding units 17 and 18 are arranged at a distance from one another and are equipped with a sanding belt running transversely to the feed direction of the workpiece 52a. The two long belt sanding units 17, 18 each have an elastic pressure bar and an endlessly rotating pressure lamella belt connected between the sanding belt and the pressure bar. Each of the two pressure bars are assigned pressure rollers 19, 20 and 21, 22, respectively, in front of and behind them, as seen in the feed direction. With the pressure rollers or rollers 19 or 2! there is a contact roller in each plane, which is actuated by the workpiece 52a passing through and which controls the downward and upward movements of the associated pressure beams. The pressure bars are provided with devices - not shown - with which the working width can be adjusted in accordance with the width of the workpieces 52a passing through.
In Vorschubrichtung der Werkstücke 52a ist hinter den beiden Langbandschleifaggregaten 17,18 ein Breitbandschleifaggregat 23 mit Druckbalken 23a angeordnet, deren Schleifband 34 im Gegensatz zu den Schleifbändern der Langbandschleifaggregate 17, 18 parallel zur Vorschubrichtung des Werkstückes 52a umläuft.In the feed direction of the workpieces 52a there is a wide belt sanding unit behind the two long belt sanding units 17, 18 23 arranged with pressure bar 23a, the sanding belt 34 of which in contrast to the sanding belts of the long belt sanding units 17, 18 rotates parallel to the feed direction of the workpiece 52a.
Mit Hilfe der erfindungsgemäßen Bandschleifmaschine werden die geradlinig transportierten Werkstücke so 52a mit zwei gegenläufigen schmalen Schleifbändern der Langbandschleifaggregate 17 und 18 quer vorgeschliffen und mit dem breiten Schleifband 34 des Breitbandschleifaggregates 23 längs nachgeschliffen, wobei durch eine mögliche Oszillationsbewegung des Breitbandschleifaggregates 23 quer zur Vorschubrichtung des Werkstückes 52a im Zusammenwirken mit den beiden Bandschleifaggregaten 17,18 und deren quer zur Vorschubrichtung des Werkstückes 52a umlaufenden Schleifbändern eine optimale Oberflächenqualität bei den großflächigen, plattenförmigen Werkstücken 52a erzielt wird.With the aid of the belt grinding machine according to the invention, the workpieces transported in a straight line are so 52a with two narrow sanding belts running in opposite directions the long belt sanding units 17 and 18 transversely pre-sanded and with the wide sanding belt 34 of the Wide belt sanding unit 23 reground lengthways, with a possible oscillating movement of the Wide belt sanding unit 23 transversely to the feed direction of the workpiece 52a in cooperation with the two belt sanding units 17, 18 and their rotating transversely to the feed direction of the workpiece 52a Sanding belts provide an optimal surface quality for the large-area, plate-shaped workpieces 52a is achieved.
