Definitions

  • the present invention relates to the field of belt grinding technology. It describes the change in the position of the sensing element unit when a segmented sanding pad is tilted and the control unit for individually controlling each segment when this sanding pad is tilted.
  • Drawing 2 showing the same arrangement as drawing 1, but after pivoting the segmented sanding pad (11, 12, 13) by the angle.
  • Drawing 3 with a starting position analogous to drawing 1, additionally with a lever device (16) for the feeler elements (15), which according to claim 1 causes the lateral displacement when the grinding pad is pivoted.
  • Drawing 6 shows a device (18) in the parallelogram structure, in which the feeler elements (15) are pivoted parallel to the segments (12).
  • the current state of the art includes knowledge of the advantages of the inclination of a belt sanding unit and the combinations of an inclinable belt sanding unit with a segment sanding pad and / or low sanding belt speeds, such as those described in patent application PCT / CH02 / 00415 with the filing date 22/07/2002.
  • Drawing 1 shows the situation with a straight grinding unit, in which the distance d between the probe elements corresponds to the distance s between the segments.
  • the feeler element T and the segment Si like the feeler element T n and the segment S n, lie in a line parallel to the passage.
  • the distance s decreases compared to the distance d.
  • Ti and Si as well as T T and S n are no longer in line.
  • the device according to drawings 3 and 4 can be supplemented by a scissors construction (17), as shown in drawing 5.

Abstract

En cas d'inclinaison du coussin à meuler segmenté (11, 12, 13) d'une meuleuse à bande continue se pose le problème de la modification de la position de la rangée (15) d'éléments détecteurs par rapport à une position de la rangée de segments (11) s'écartant de la rangée d'éléments détecteurs, par exemple une position perpendiculaire par rapport à cette rangée d'éléments détecteurs. La présente invention permet la compensation des écarts se produisant par le déplacement latéral des éléments de détection à l'aide d'un dispositif levier (16) ou par un basculement de la rangée des éléments de détection selon une structure en parallélogramme (18). Les segments (11) sont utilisés selon la détermination des propriétés de la pièce par les éléments de détection (15), au moyen d'une unité de commande électronique individuellement programmable.
