Abstract

The invention describes devices consisting of a combination of oblique to feed direction aligned belt sanding assemblies, with drives or devices for low sanding belt speeds and/or with conventional, or modified for sanding belt oblique operation, electronic segmented sanding pad. The oblique alignment of the sanding unit can be adjusted steplessly. Its application for both oblique sanding and, when so aligned, sanding directly in the direction of feed meets the requirements of intermediate sanding between paint or varnish coats, as well as those of wood sanding.

Aus dieser von der Schrägstellung des Segmentschleifkissens 13 abweichenden Anordnung der Tastrollenreihe 14, resultieren über die Arbeitsbreite unterschiedliche Distanzen zwischen den einzelnen Tastrollen und den entsprechenden, von ihnen angesteuerten Segmenten. So ist die Strecke a kürzer als die Strecke b.

Zum heutigen Stand der Technik gehört das Wissen um Vorrichtungen mit schräg zur Vorschubrichtung angeordneten Bandschleifaggregaten. Aus der Industrie bekannt sind Oben-/Unten-Schleifanlagen mit Bandschleifaggregaten, die leicht schräg zur Durchlaufrichtung angeordnet sind. Die beiden den für den Kontakt des Werkstückes zum Schleifband erforderlichen Anpressbalken, die sog. Schleifkissen16, 17, sind 90° zum Werkstück angeordnet. Diese 90° Anordnung des Schleifkissens im schräggestellten Schleifband erfordert viel Platz beanspruchende Schleifaggregate, garantiert aber den geraden Durchzug des Schleifguts auch beim Unterbruch der Werkstückauflage, wie er für das Schleifen von unten unvermeidlich ist.The current state of the art includes the knowledge of devices with belt grinding units arranged obliquely to the feed direction. From the industry are known top / bottom grinding systems with belt sanding units, which are arranged slightly inclined to the direction of passage. The two required for the contact of the workpiece to the grinding belt Anpressbalken, the so-called. Schleifkissen16, 17, are arranged 90 ° to the workpiece. This 90 ° arrangement of the sanding pad in the inclined sanding belt requires a lot of space-demanding sanding units, but guarantees the straight passage of the sanding material even when interrupting the workpiece support, as it is unavoidable for grinding from below.

In Fachkreisen bekannt ist auch, dass in Vorschubrichtung schräglaufende Schleifbänder gegenüber solchen, die in gerader Vorschubrichtung arbeiten, den Vorteil haben, dass sich ihre allfälligen Fehler (z. B. Streufehler, Komausbrüche, Verunreinigungen mit Leim, Staub, etc.) nicht in einer geraden Linie, sondern seitlich versetzt auf dem Werkstück repetieren. Sie treten dadurch deutlich weniger intensiv und weniger auffällig in Erscheinung. Die schrägen Schleifspuren selbst stören nicht auf homogenen Werkstücken oder solchen die nach dem Schleifen weiterbehandelt (kaschiert, überspritzt etc.) werden, dagegen natürlich auf strukturierten Oberflächen (wie z. B. bei maseriertem Holz). Das Schleifen mit schräggestellten Bändern ist deshalb kaum verbreitet. Eine Ausnahme sind die obig erwähnten Oben-/Untenschleifanlagen. Aber auch bei diesen beschränkt sich die Anwendung auf sog. MDF-Platten mit hohen Anforderungen an die Oberflächenqualität. Keinen entsprechenden Bedarf an die Makellosigkeit ihrer Oberfläche verlangen dagegen z. B. Spanplatten (diese werden in der Regel nachträglich furniert), während das Furnier- oder Massivholz, wie erwähnt, üblicherweise keine schrägen Schliffspuren toleriert. Ein Vorteil schräglaufender Schleifbänder würde sich dagegen beim Lackzwischenschliff zeigen. Für diese bisher nicht bekannte Anwendung sollten allerdings weitere Voraussetzungen berücksichtigt werden: So müssen die schräggestellten Schleifaggregate wegen der dünnen Lackschicht mit tiefen Schnittgeschwindigkeiten des Schleifbandes (d. h. etwa 50 % oder weniger der Standardgeschwindigkeit für den Holzschliff) und/oder einem speziell subtilen Schleifkissen kombiniert werden. Die entsprechenden Vorrichtungen - z. B. die Drehzahlregelung mittels Frequenzumformer und die Verwendung elektronisch gesteuerter sog. Segmentschleifkissen - sind zwar bekannt, in der Praxis jedoch noch nicht ihre gleichzeitige Verwendung mit schräggestellten Schleifaggregaten.It is also known to those skilled in the art that in the feed direction oblique grinding belts have the advantage over those which work in a straight feed direction that their possible defects (eg scattering defects, breakouts, contamination with glue, dust, etc.) do not occur in one Straight line, but laterally offset on the workpiece repeat. As a result, they appear much less intense and less noticeable. The oblique sanding marks themselves do not interfere with homogeneous workpieces or those that are further treated after sanding (laminated, overmoulded, etc.), but, of course, on structured surfaces (such as, for example, woodgrained wood). The grinding with slanted bands is therefore hardly common. An exception are the above-mentioned top / bottom grinding machines. But even with these applications is limited to so-called. MDF boards with high demands on the surface quality. No corresponding demand for the flawlessness of their surface, however, z. As chipboard (these are usually subsequently veneered), while the veneer or solid wood, as mentioned, usually tolerates no oblique grinding marks. An advantage of oblique abrasive belts, however, would be the intermediate lacquer finish. For this hitherto unknown application, however, further requirements should be taken into account: For example, the inclined abrasive aggregates must be combined with low grinding velocities (ie about 50% or less of the standard groundwood speed) and / or a specially subtle sanding pad because of the thin varnish layer. The corresponding devices -. As the speed control by means of frequency converter and the use of electronically controlled so-called. Segmentschleifkissen - are known, in practice, however, not yet their simultaneous use with slanted grinding units.

Im Gegensatz zu der industriellen Plattenfertigung (z. B. MDF-Platten) erfolgt das Lackieren und der Lackzwischenschliff vor allem in mittelständischen Handwerkesbetrieben. Diese haben spezielle Anforderungen: Zumeist sollen mit der selben Maschine sowohl Holzplatten (massive oder furnierte) wie Lackoberflächen geschliffen werden. Während erstere den Geradeschliff verlangen, bringt für letztere der Schrägschliff die genannten Vorteile der Oberflächengüte. Die Schleifaggregate müssen somit umstellbar sein. Falls auch das Schleifkissen selbst schräg angeordnet ist - und es sich bei diesem um ein Segmentschleifkissen handelt - muss gleichzeitig eine automatische Umstellung von gerade auf schräg (und umgekehrt) der Segmente 12 dieses elektronischen Segmentschleifkissens um ihre Drehachse 21 erfolgen, was Gegenstand der vorliegenden Erfindung ist. Da der Einsatz der Segmente 12 durch Tastrollen 14 am Einlauf gesteuert wird, muss auch die Ansteuerung "schrägstellbartauglich" gemacht werden. Dies entweder durch die Verwendung einer segmentierten Druck- oder Tastrollenreihe 14, die parallel zum Schleifaggregat mitgedreht wird (und die sich z. B. über eine Parallelogramm-Aufhängung in Vorschubdirektion ausrichtet) oder bei fixer Position der Tastrollen über eine bei der Steuerung zu berücksichtigende Kompensation der über die Arbeitsbreite ungleichen Streckenverzögerung zwischen Tastrollen und Segmenten.In contrast to industrial panel production (eg MDF panels), lacquering and intermediate lacquer sanding are mainly used in medium-sized craft businesses. These have special requirements: In most cases, both wood panels (solid or veneered) and painted surfaces should be sanded with the same machine. While the former require straight-cut, the latter gives the latter the advantages of surface finish for the latter. The grinding units must therefore be convertible. If the sanding pad itself is arranged obliquely - and this is a segment sanding pad - an automatic change from straight to oblique (and vice versa) of the segments 12 of this electronic segment sanding pad about its axis of rotation 21 has to be carried out simultaneously, which is the subject of the present invention , Since the use of the segments 12 is controlled by touch rollers 14 at the inlet, the control must also "tiltable" be made. This is done either by the use of a segmented row of pressure or tracer rollers 14, which is rotated parallel to the grinding unit (and which, for example, aligns with a parallelogram suspension in the feed direction) or with a fixed position of the tracing rollers via a compensation to be taken into account in the control the over the working width unequal distance delay between touch rollers and segments.

Da nicht alle Oberflächen, Lacksorten etc. gleiche Eigenschaften aufweisen, sollte die Schrägstellung der Schleifaggregate und die Verstellung der Segmente 12 des Segmentschleifkissens 13 stufenlos im Drehwinkel erfolgen können.Since not all surfaces, types of lacquer etc. have the same properties, the inclination of the grinding units and the adjustment of the segments 12 of the segment grinding pad 13 should be able to be infinitely variable in the angle of rotation.

Eine weitere Anforderung des mittelständischen Betriebes geht dahin, dass die Schleifmaschine kompakt gebaut sein soll. Diesem Anspruch wird Genüge getan durch Drehung (mit beidseitiger Abstützung) des kompletten Aggregatkörpers (inkl. Bandspannung, Oszillation, Sicherheits- und Absaugeinrichtungen), einschliesslich auch des Schleifkissens 13. Vorzugsweise nicht jedoch des Antriebsmotors 18. Aus verschiedenen möglichen Drehpunkten wird im Interesse einer kompakten Bauweise derjenige der Vertikal-Mittelachse des Antriebsriemens 19 gewählt.Another requirement of medium-sized companies is that the grinding machine should be compact. This requirement is met by rotation (with support on both sides) of the entire aggregate body (including belt tension, oscillation, safety and suction), including the grinding pad 13. Preferably, however, not the drive motor 18. From various possible pivot points is in the interest of a compact Construction of that selected the vertical center axis of the drive belt 19.
