Description

Meßgeräte, bei denen das Meßergebnis an einem über einer Skala sich bewegenden Zeiger abgelesen wird, sind in der Meßtechnik für körperliche und physikalische Messungen weit verbreitet. Bei Reihenmessungen beschränkt sich die Beobachtung des Zeigers meist darauf, daß festgestellt wird, ob der Zeiger in der Ablesestellung innerhalb eines an der Skala durch Toleranzmarken begrenzten Gutfeldes steht oder außerhalb desselben. Im letzteren Falle muß in der Regel auch noch festgestellt werden, ob der Zeiger nach der Plusseite oder nach der Minusseite aus dem Gutfeld herausgerückt ist. Diese Feststellungen lassen sich durch Benutzung elektrischer Licht- oder Schallsignale wesentlich erleichtern. Zu diesem Zweck muß das Zeigerinstrument mit entsprechenden elektrischen Steuermitteln versehen sein. Bisweilen wird von diesen Steuermitteln aus nicht nur die Signaleinrichtung gesteuert, sondern auch eine mit elektromagnetisch betätigten Klappen versehene automatische Sortiereinrichtung, die das Meßgut je nach der Ablesestellung des Zeigerinstrumentes nach Gut oder Plus oder Minus sortiert.Measuring devices in which the measurement result is on a scale above Moving pointer reads are used in metrology for physical and physical Measurements widely used. In the case of serial measurements, the observation of the Pointer usually points out that it is determined whether the pointer is in the reading position is within a good field delimited on the scale by tolerance marks or outside of it. In the latter case, as a rule, it must also be determined whether the pointer is on the plus side or on the minus side from the Gutfeld has moved out. These determinations can be made by using electrical Make light or sound signals much easier. For this purpose the pointer instrument be provided with appropriate electrical control means. Sometimes from These control means not only control the signaling device, but also an automatic sorting device equipped with electromagnetically operated flaps, which the measured material depending on the reading position of the pointer instrument according to good or plus or minus sorted.

Gegenüber den bekannten Meßgeräten der beschriebenen Art besitzt das den Gegenstand der Erfindung bildende Zeigerinstrument die Neuerung und den Vorteil, daß die elektrische Steuerung vom Zeiger aus erfolgt, also von einem Geräteteil aus, der infolge großer zurückzulegender Wege zu scharf abgegrenzter Unterscheidung besonders gut geeignet ist. Dieser Erfindungsgedanke ist im folgenden beschrieben und in den Abb. i und 2 beispielsweise und schematisch. dargestellt.Compared to the known measuring devices of the type described has the pointer instrument forming the subject of the invention the innovation and the advantage, that the electrical control takes place from the pointer, so from a device part from that, as a result of the long distances to be covered, to sharply delimited distinctions is particularly well suited. This inventive concept is described below and in Figs. i and 2 by way of example and schematically. shown.

Abb. i zeigt das Gerät lm Querschnitt, Abb. 2 in einer Vorderansicht auf den als durchsichtig gedachten Gerätedeckel.Fig. I shows the device in cross section, Fig. 2 in a front view on the device cover, which is thought to be transparent.

In den Abbildungen bedeutet i das Gerätegehäuse, das durch einen Deckel 2 aus Isolationsmaterial abgeschlossen ist. Am Deckel ist über den ganzen Gerätemeßbereich und konzentrisch zur Zeigerachse eine bogenförmige Kontaktschiene 3 für Gut verlegt, die im beschriebenen Beispiel einen geschlossenen Kreisring darstellt. Ebenfalls konzentrisch zur Zeigerachse sind am Deckel 2 zwei weitere konzentrische Kontaktschienen 4 bzw. 5 für Plus bzw. Minus angeordnet. Letztere sind verstellbar und werden vor Beginn des Messens so eingestellt, daß zwischen ihnen eine das Gutfeld begrenzende Lücke entsteht. Der Zeiger 6 selbst ist im Deckel 2 drehbar gelagert und wird . bei der Messung durch irgendwelche an sich bekannte und deshalb in den Abbildungen nicht eingezeichnete Mittel in Drehung versetzt: Im Gehäuse i ist eine in Richtung der Zeigerachse verschiebbare Scheibe 7 angeordnet, die einen zur Zeigerachse konzentrischen bogenförmigen Wulst 8 aufweist, der im beschriebenen Beispiel einen geschlossenen Kreisring bildet. Sobald der Zeiger 6 bei der Messung in der Ablesestellung angekommen ist, wird die Scheibe 7 mit dem Wulst 8 durch irgendwelche nicht zur Erfindung gehörige Mittel gegen den Zeiger 6 gedrückt. . Infolge der federnden Nachgiebigkeit des letzteren entsteht dabei Kontakt zwischen einer der drei Kontaktschienen und dem Zeiger 6 bzw. der Scheibe 7, die gegen das Gerätegehäuse nicht isoliert ist. Dabei wird je nach der Stellung des Zeigers einer der drei für Gut, Plus und Minus vorgesehenen-Stromkreise geschlossen, die in den Abbildungen durch die von den Kontaktschienen abgehenden Leiter und den von der Scheibe 7 abgehenden Leiter angedeutet sind. Nach Beendigung des Meßvorganges wird die Schreibe 7 durch die Feder 9 wieder ausgerückt, so daß der Zeiger 6 zurückfedern kann. Damit wird der Stromfluß unterbrochen und der Zeiger 6 wieder freigegeben.In the figures, i means the device housing that is covered by a cover 2 is completed from insulation material. The cover covers the entire device measuring range and concentric to the pointer axis, an arcuate contact rail 3 for goods is laid, which represents a closed circular ring in the example described. Likewise concentric to the pointer axis, there are two further concentric contact rails on the cover 2 4 or 5 arranged for plus or minus. The latter are adjustable and are in front The beginning of the measurement set so that between them a good field delimiting Gap arises. The pointer 6 itself is rotatably mounted in the cover 2 and is. when measuring by any known per se and therefore in the figures Not shown means set in rotation: In the housing i is one in the direction the pointer axis displaceable disk 7 is arranged, which is concentric to the pointer axis Has arcuate bead 8, which is closed in the example described Forms circular ring. As soon as the pointer 6 has reached the reading position during the measurement is, the disc 7 with the bead 8 by any not belonging to the invention Means pressed against the pointer 6. . As a result of the resilient resilience of the latter This creates contact between one of the three contact rails and the pointer 6 or the disc 7, which is not isolated from the device housing. It will ever according to the position of the pointer, one of the three circuits provided for good, plus and minus closed, those in the illustrations by the outgoing from the contact rails Head and the outgoing conductor from the disc 7 are indicated. After completion of the measuring process, the disk 7 is disengaged again by the spring 9, so that the pointer 6 can spring back. This interrupts the flow of current and the pointer 6 released again.

Werden die drei Kontaktschienen 3, 4 und 5, wie in Abb. i dargestellt, gleich hoch gemacht, dann müssen am Zeiger 6 zwei Kontaktstücke io und i i verschiedener Höhe angebracht werden. Dadurch wird zeichnungsgemäß erreicht, daß der Zeiger 6, wenn er in Ablesestellung nicht auf der von der Plusschiene und der Minusschiene begrenzten, das Guffeld darstellenden Lücke steht, nur mit einer dieser beiden Schienen in Berührung kommt, nicht aber mit der Gutschiene.If the three contact rails 3, 4 and 5, as shown in Fig. I, made the same, then on the pointer 6 two contact pieces io and i i must be different Height to be attached. It is thereby achieved, as shown in the drawing, that the pointer 6, if it is not in the reading position on the plus rail and the minus rail limited gap that represents the guff field, only with one of these two rails comes into contact, but not with the voucher.
