Description

Die vorliegende Erfindung bezieht sich auf eine Bandschleifvorrichtung gemäß dem Oberbegriff des Anspruchs. Sie beschreibt die Veränderung der Lage der Segmente bei der Schrägstellung eines segmentierten Schleifkissens. Eine solche Vorrichtung ist aus WO 2004/009290 A bekannt.The present invention relates to a belt grinding apparatus according to the preamble of the claim. It describes the change in the position of the segments in the oblique position of a segmented sanding pad. Such a device is out WO 2004/009290 A known.

Die Schrägstellung eines segmentierten Schleifkissens ist beschrieben in den Patentanträgen mit den internationalen Aktenzeichen/internationalen Anmeldedaten PCT/CH/02/00415 vom 22/7/2002 und PCT/CH/2004/000509 vom 16/8/2004.The inclination of a segmented sanding pad is described in the patent applications with the international file reference / international registration data PCT / CH / 02/00415 from 22/7/2002 and PCT / CH / 2004/000509 from 16/8/2004.

Zur Illustration der gemäß dem Anspruch vorliegenden Erfindung dienen:

  • die Zeichnung 1 mit der Darstellung der Ausgangslage, nämlich der Anordnung eines segmentierten Schleifkissens mit den individuell ansteuerbaren Segmenten (11), den Schleifband-Umlenkwalzen (12 und 13), den in Durchlaufrichtung (14) vor dem Kissen positionierten Tastelementen (15), sowie einer Hebel-Vorrichtung (16) für die Schleifelemente (11), die bei Schwenkung der Tastelemente das seitliche Verschieben dieser Segmente bewirkt.
  • die Zeichnung 2 mit der gleichen Anordnung und Vorrichtung wie Zeichnung 1, jedoch nach erfolgter Schrägstellung des segmentierten Schleifkissens (11, 12, 13) um den Winkel α.
  • die Zeichnung 3 mit einer Anordnung wie Zeichnung 1, jedoch einem fixen Anschlag (17), mit Gleitern (18) versehenen Segmenten (11), einer Führungsachse (20), einer Gegendruckvorrichtung (19) und der Darstellung der Längsachsen (21).
  • die Zeichnung 4 mit der gleichen Anordnung und Vorrichtung wie Zeichnung 3, jedoch nach erfolgter Schrägstellung des segmentierten Schleifkissens (11, 12, 13) um den Winkel α.
To illustrate the invention according to the claim serve:
  • the drawing 1 with the representation of the initial position, namely the arrangement of a segmented sanding pad with the individually controllable segments (11), the sanding belt guide rollers (12 and 13), in the direction of passage (14) positioned in front of the pad feeler elements (15), and a lever device (16) for the grinding elements (11), which causes the lateral displacement of these segments when the scanning elements are pivoted.
  • the drawing 2 with the same arrangement and apparatus as in drawing 1, but after the inclination of the segmented sanding pad (11, 12, 13) by the angle α.
  • the drawing 3 with an arrangement as in drawing 1, but a fixed stop (17), with gliders (18) provided with segments (11), a guide axis (20), a counter-pressure device (19) and the representation of the longitudinal axes (21).
  • the drawing 4 with the same arrangement and apparatus as in drawing 3, but after the inclination of the segmented sanding pad (11, 12, 13) by the angle α.

Zum heutigen Stand der Technik gehört das Wissen um die Vorteile der Schrägstellung eines Bandschleifaggregates und der Kombination eines schrägstellbaren Bandschleifaggregates mit einem Segmentschleifkissen, wie sie in obig erwähnten Patentanträgen ausgeführt werden.Knowledge of the advantages of skewing of a belt grinding unit and the combination of a tiltable belt grinding unit with a segment grinding pad, as they are carried out in the patent applications mentioned above, belong to the current state of the art.

Aus dem Patentantrag PCT/CH/2004/000509 ist eine Vorrichtung bekannt, welche bei Schrägstellung eines Segmentschleifkissens mittels einer Hebelvorrichtung oder eines Stellmotors die Tastelemente T1 ... Tn wieder annähernd in Übereinstimmung mit den Segmenten S1... Sn bringt. Die vorliegende Erfindung beschreibt nun eine Hebelvorrichtung oder eine andere dem selben Zweck dienende Vorrichtung, wie beispielsweise einen Stellmotor, der die Tastelemente (15) in ihrer ursprünglichen Position belässt, jedoch die Segmente S1 ... Sn seitlich so verschiebt, dass sie wieder annähernd in Übereinstimmung mit den Tastelementen sind.From the patent application PCT / CH / 2004/000509 a device is known which brings the probe elements T 1 ... T n again approximately in accordance with the segments S 1 ... S n in oblique position of a Segmentschleifkissens by means of a lever device or a servomotor. The present invention now describes a lever device or another device serving the same purpose, such as a servomotor, which leaves the sensing elements (15) in their original position, but the segments S 1 ... S n laterally shifts so that they again are approximately in accordance with the probe elements.

Die hier geschilderte Vorrichtung hat gegenüber derjenigen des Patentantrages PCT/CH/2004/000509 den Vorteil, dass die fixe Tastelementenreihe mehrere aufeinanderfolgende Segmentschleifkissen mit unterschiedlichen Gerade-/ Schrägstellungen bedienen kann, während eine seitlich verschobene Tastelementenreihe nur einem einzigen spezifischen Schrägstellungswinkel des/der Schleifkissen entspricht.The device described here has opposite to the patent application PCT / CH / 2004/000509 the advantage that the fixed Tastelementenreihe can serve several consecutive Segmentschleifkissen with different straight / oblique positions, while a laterally displaced Tastelementenreihe corresponds to only a single specific skew angle of the / the sanding pad.

Ferner befasst sich die vorliegende Erfindung mit dem Problem, dass je grösser der Winkel α. der Schrägstellung wird, desto mehr sich bei einer Anordnung gemäss Zeichnungen 1 und 2 die Segmente (11) von Ihrer Senkrechten zu den Tastelementen (15) entfernen. Zur Kompensation dieser Differenzen empfiehlt sich deshalb anstelle der Hebel-Vorrichtung (16) eine Anordnung mit fixem Anschlag (17), gleitenden Segmenten (11, 18), einer Führungsachse (20) und einer Gegendruckvorrichtung (19), wie sie Zeichnungen 3 und 4 zeigen. An Stelle dieser mechanischen Anordnung können aber selbstverständlich auch andere dem gleichen Zweck dienende Vorrichtungen, beispielsweise motorischer, elektronischer oder pneumatischer Art, treten.Furthermore, the present invention deals with the problem that the larger the angle α. the inclination is, the more in an arrangement according to drawings 1 and 2 remove the segments (11) from their perpendicular to the probe elements (15). To compensate for these differences, therefore, instead of the lever device (16), an arrangement with a fixed stop (17), sliding segments (11, 18), a guide shaft (20) and a counter-pressure device (19), as shown in drawings 3 and 4 demonstrate. Of course, instead of this mechanical arrangement, other devices serving the same purpose, for example of a motor, electronic or pneumatic type, can also be used.

Claims (1)

  1. Belt sanding device with a segmented sanding pad, on which, in its oblique position, the segments (11) of the sanding pad are positioned in the longitudinal axis (21) of the associated, fixed and in the direction of feed (14) in front of the sanding pad aligned sensor elements (15), characterized in that the longitudinal axes (21) of the individual sensor elements (15) and the respective segments (11) are aligned with respect to each other when the gaps between the segments (11) are adjusted to the longitudinal axes (21) of the sensor elements (15).
