Description

Die Erfindunghezieht sich auf ein elektro-optisches Meßgerät, das direkt im Fabrikationsgang die Toleranzkontrolle von Drähten, Bändern und Profilstangen ermöglicht. The invention relates to an electro-optical measuring device, the The tolerance control of wires, strips and profile bars directly in the production aisle enables.

Bekannt sind mechanische Toleranzmesser für Drähte, die mit Fühlhebeln das Maß abtasten und über entsprechende Übersetzungen bei Erreichen von Grenzwerten elektrische Kontakte betätigen. Mechanical tolerance meters for wires with feeler levers are known scan the dimension and use corresponding gear ratios when limit values are reached operate electrical contacts.

Auch Schreibgeräte werden auf diese Weise mechanisch gesteuert zur laufenden Kontrolle der Toleranz.Writing implements are also mechanically controlled in this way ongoing control of tolerance.

Erfindungsgemäß wird die Abtastung eines Dickenmaßes von Drähten, Bändern oder Profilstäben durch ein paralleles Lichtbündel vorgenommen. Das in der Toleranz zu kontrollierende Material bildet dabei eine scharfe Begrenzung des Lichtstrahls, während eine feststehende Messerkante die andere Begrenzung einer so gebildeten Spaltblende darstellt. Hinter dieser Spaltblende tritt das Lichtbündel durch eine Linse mit kurzer Brennweite und wird in der Ebene des Spiegels S I in zwei Teile zerlegt. Die eine Hälfte des Lichtbündels trifft auf eine Photozelle, während die andere Hälfte über den Spiegel S 2 auf die Mattscheibe M geworfen wird (s. Abbildung). Im Ausgang eines Photozellenverstärkers liegt ein Instrument, das durch die Anzeige des Photostroms das zu kontrollierende Maß abzulesen gestattet. Bei zehnfacher Vergrößerung des Lichtspalts auf der Mattscheibe können dort 0,05 mm Toleranz durch Maßlinien in 0,5 mm Abstand noch genau abgelesen werden. Um verschiedene Drahtdurchmesser mit einer Vorrichtung kontrollieren zu können, ist die Rollenführung R iii der Höhe verstellbar. Für die genaue Einstellung ist jedoch keine Mikrometerablesung erforderlich, weil der Lichtspalt zwischen Material und fester Blendenkante auf der Mattscheibe in zehnfacher Vergrößerung zu beobachten ist. Die Einstellung wird nach dem Bild auf der Mattscheibe vorgenommen. According to the invention, the scanning of a gauge of wires, Ribbons or profile bars made by a parallel beam of light. That in the The material to be checked for tolerance forms a sharp limitation of the light beam, while a fixed knife edge is the other limit of one so formed Represents slit diaphragm. Behind this slit the light beam passes through a Lens with short focal length and is in the plane of the mirror S I in two parts disassembled. Half of the light beam hits a photocell, while the the other half is thrown over the mirror S 2 onto the focusing screen M (see illustration). At the output of a photocell amplifier there is an instrument that is shown by the display of the photocurrent allowed to read off the level to be controlled. At ten times magnification of the light gap on the ground glass there can be 0.05 mm tolerance through dimension lines can still be read exactly at a distance of 0.5 mm. To different wire diameters To be able to control with a device, the roller guide R iii of the height adjustable. However, no micrometer reading is required for accurate adjustment, because the light gap between the material and the fixed edge of the screen on the focusing screen can be observed at ten times magnification. The setting is according to the picture made on the screen.

Der Aufbau des Geräts entbehrt jeder empfindlichen Mechanik und wird für rauhe Betriebsbedingungen sehr robust gehalten.The structure of the device lacks any sensitive mechanics and is kept very robust for rough operating conditions.

Für die Einhaltung von Über- und Untertoleranzgrenzen sind zwei Lichtschranken gleichen Aufbaus in einem Gerät kombiniert erforderlich. Die Übertoleranzseite wird so eingestellt, daß zwischen dem zu kontrollierenden Material mit Sollmaß und der festen Messerkante ein Lichtspalt in Größe der zugelassenen Toleranz entsteht. Erreicht das durchlaufende Material die vorgesehene Grenze, so wird der Lichtspalt abgedeckt und die Photozelle verdunkelt. Ein Schweliwertrelais im Ausgang des Verstärkers gibt einen Steuerimpuls an einen Signalgeber oder sonstige zu steuernde Organe. Die Untertoleranzseite wird so eingestellt, daß bei Sollmaß gerade der Lichtspalt geschlossen ist. Tritt Untertoleranz ein, so signalisiert die zugeordnete Photozelle. There are two light barriers for compliance with over and under tolerance limits the same structure combined in one device is required. The over-tolerance side will set so that between the material to be checked with nominal size and the fixed knife edge creates a light gap in the size of the permitted tolerance. Achieved the material passing through the intended limit, the light gap is covered and the photocell is darkened. A threshold relay in the output of the amplifier gives a control impulse to a signal generator or other organs to be controlled. The lower tolerance side is set in such a way that the light gap is just the target dimension closed is. If there is an under-tolerance, the assigned photocell signals.

Für Drähte, Bänder und Profilstäbe sind geeignete, für jeden Zweck einsetzbare Vorrichtungen zur Material führung vorgesehen. For wires, strips and profile bars are suitable for every purpose usable devices for material management provided.

Die Abbildting zeigt das Prinzipschema eines elektro-optischen Toleranzmessers, woraus die Lichtführung über den auf der Führungsrolle R liegenden Draht D und die feste Blendekante B durch dieLinseauf diePhotozelleF einerseits und über die Spiegel S I und S 2 auf die Alattscheibe andererseits zu ersehen ist. The picture shows the principle of an electro-optical tolerance meter, from which the light guide on the lying on the guide roller R wire D and the fixed diaphragm edge B through the lens onto the photocell F on the one hand and over the mirror S I and S 2 can be seen on the other hand on the Alatt disk.
