Abstract

On inclined installation of the segmented grinding platen (11, 12, 13) of a through belt grinding machine, the problem arises of the altered arrangement of the scanning element series (15) relative to a position for the segment series (11) which is different thereto, for example, at right angles. According to the invention, the resulting deviations are allowed for by the lateral displacement of the scanning elements by means of a lever device (16), or by a pivoting of the scanning element series in a parallelogram construct (18). The application of the segments (11), following the determination of the workpiece properties by the scanning elements (15), occurs using an individually programmable electronic controller.

Titel: Vorrichtungen zur Veränderung der Lage der Tastelemente-Einheit bei Schrägstellung eines segmentierten Schleifkissens und Steuereinheit zu dessen AnsteuerungTitle: Devices for changing the position of the probe element unit when a segmented sanding pad is inclined and control unit for controlling it

Sie beschreibt die Veränderung der Lage der Tastelemente-Einheit bei der Schrägstellung eines segmentierten Schleifkissens und die Steuereinheit zur individuellen Ansteuerung eines jeden einzelnen Segments bei der Schrägstellung dieses Schleifkissens.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.

• die Zeichnung 6 zeigt eine Vorrichtung (18) im Parallelogramm-Aufbau, bei der die Tastelemente (15) parallel zu den Segmenten (12) mitgeschwenkt werden.• Drawing 6 shows a device (18) in the parallelogram structure, in which the feeler elements (15) are pivoted parallel to the segments (12).

Zum heutigen Stand der Technik gehört das Wissen um die Vorteile der Schrägstellung eines Bandschleifaggregates und der Kombinationen eines schrägstellbaren Bandschleifaggregates mit einem Segmentschleifkissen und/oder tiefen Schleifbandgeschwindigkeiten, wie sie im Patentantrag PCT/CH02/00415 mit Anmeldedatum 22/07/2002 ausgeführt werden.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.
Dadurch, dass sich bei Schrägstellung des Schleifkissens die Lage der Segmente (11 ) relativ zur Lage der Tastelemente (15) verändert, würde die durch die Tastelemente 15 ermittelten Werkstückeigenschaften jedoch nur noch unvollständig oder unrichtig an die entsprechenden Segmente (15) übermittelt, sofern diese Abweichungen nicht entsprechend beim Segmenteinsatz berücksichtigt werden. Zeichnung 1 zeigt die Situation bei geradem Schleifaggregat, bei welchem die Distanz d zwischen den Tastelementen mit der Distanz s zwischen den Segmenten übereinstimmt. Das Tastelement T und das Segment Si liegen ebenso wie das Tastelement Tn und das Segment Sn in zum Durchlauf paralleler Linie. Bei Drehung der Segment-Reihe um den Winkel α, wie in Zeichnung 2 dargestellt, verkleinert sich die Distanz s gegenüber der Distanz d. Zudem liegen Ti und Si sowie TT und Sn nicht mehr in Linie. Diese Abweichungen führen dazu, dass, wie erwähnt, der Einsatz der Segmente (12) nicht mehr mit der durch die Tastelemente (15) ermittelten Werkstückeigenschaften übereinstimmt.Because the position of the segments (11) changes relative to the position of the feeler elements (15) when the grinding pad is inclined, the workpiece properties determined by the feeler elements 15 would only be transmitted incompletely or incorrectly to the corresponding segments (15), provided that the latter Deviations are not taken into account when using the segment. 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. When the segment row is rotated by the angle α, as shown in drawing 2, the distance s decreases compared to the distance d. In addition, Ti and Si as well as T T and S n are no longer in line. These deviations mean that, as mentioned, the use of the segments (12) no longer corresponds to the workpiece properties determined by the feeler elements (15).
Zur Korrektur solcher Abweichungen eignen sich folgende Vorrichtungen:The following devices are suitable for correcting such deviations:
Zum einen eine Hebelvorrichtung wie sie Zeichnung 3 zeigt oder auch ein Stellmotor, die/der im wesentlichen die Tastelemente Ti ... Tn wieder näherungsweise in Übereinstimmung mit den Segmenten ST ... Sn bringt.On the one hand a lever device as shown in drawing 3 or also a servomotor which essentially brings the touch elements Ti ... T n back into approximation with the segments S T ... S n .
Sollen zudem auch die Abweichungen aufgrund der veränderten Distanzen zwischen den Segmenten bei der Positionierung der Tastelemente mitberücksichtigt werden, kann die Vorrichtung gemäss Zeichnungen 3 und 4 um eine Scherenkonstruktion (17), wie sie Zeichnung 5 zeigt, ergänzt werden.If the deviations due to the changed distances between the segments are also to be taken into account when positioning the feeler elements, the device according to drawings 3 and 4 can be supplemented by a scissors construction (17), as shown in drawing 5.
Eine etwas aufwändigere Konstruktion, die die Tastelemente Ti ... Tn in Linie mit den Segmenten Si ... Sn belässt und so auch die in Zeichnung 2 gezeigten Distanzfehler vermeidet, zeigen die Zeichnungen 6 und 7 mit einer Schwenkvorrichtung (18) der Tastelementen-Reihe im Parallelogramm-Aufbau.A somewhat more complex construction, which leaves the probe elements Ti ... T n in line with the segments Si ... S n and thus also avoids the distance errors shown in drawing 2, is shown in drawings 6 and 7 with a swivel device (18) Probe element series in a parallelogram structure.
Für die Vorrichtungen gemäss Zeichnungen 3, 4, 5 gilt zudem, dass wegen der unterschiedlichen Distanzen der einzelnen Paare von Tastelementen (15) mit den zugehörigen Segmenten (12) die Ansteuerung spezifisch für jedes einzelne dieser Paare erfolgen muss und nicht wie bei der herkömmlichen Konstruktion beim Geradeschliff, wie sie in Zeichnung 1 und 2 gezeigt wird, oder bei der der Parallelogramm-Vorrichtung gemäss Zeichnung 6 und 7, für alle Tastelemente (15) und Segmente (12) einheitlich erfolgen kann. Die Ansteuerung der Segmente nach den durch die Tastelemente ermittelten Werkstückparametern erfolgt bei den Anordnungen gemäss Zeichnungen 3, 4, 5 durch eine speziell programmierte elektronische Steuereinheit. It also applies to the devices according to drawings 3, 4, 5 that, because of the different distances of the individual pairs of sensing elements (15) with the associated segments (12), the control must be specific to each of these pairs and not as in the conventional design for straight grinding, as shown in drawings 1 and 2, or for the parallelogram device according to drawings 6 and 7, for all probe elements (15) and segments (12) can be made uniformly. The control of the segments according to the workpiece parameters determined by the feeler elements takes place in the arrangements according to drawings 3, 4, 5 by a specially programmed electronic control unit.
