Gegenstand der Erfindung ist eine Einrichtung für lichtelektrisch oder durch Schleifkontakte abzutastende Skalen von Waagen oder ähnlichen Meßvorrichtungen zur fehlerfreien Abtastung der Skala an den Übergangsstellen von einer Dekade zur nächstfolgenden.The subject of the invention is a device for photoelectrically or by sliding contacts to be scanned Scales of scales or similar measuring devices for error-free scanning of the Scale at the transition points from one decade to the next.
Skalen lichtelektrisch abzutasten und die Ergebnisse auf ein Anzeige- oder Druckwerk zu übertragen, ist bekannt. Es ist auch schon versucht worden, die durch die Breite des Tastschlitzes im Abtastorgan unter Umständen mögliche Doppelzählung an den Dekadenübergangsstellen durch zusätzliche Einrichtungen zu vermeiden.Scanning scales photoelectrically and transferring the results to a display or printing unit, is known. Attempts have also been made to reduce the width of the feeler slot in the Scanning organ under certain circumstances possible double counting at the decade transition points avoid additional facilities.
So hat man bei mechanischer Abtastung des Wiegeergebnisses mittels Schleifkontakten einen gegenüber der Skala erhöht angeordneten Abtastpunkt vorgesehen, der eine Umschaltung auf ein zweites, seitlich versetztes Abtastorgan bewirkt. Da dieser erhöhte Abtastpunkt ebenso groß wie eine Skaleneinheit ausgeführt sein muß und dieser dabei wie eine Teilungseinheit wirkt, kann hierdurch die gewünschte Genauigkeit in der Korrektur und in der Abtastung niemals voll erreicht werden, schon deswegen, weil die Abtastbreite zu groß gewählt werden muß. Es besteht außerdem die Möglichkeit, am Dekadenschnittpunkt Falschdrucke zu erhalten, schon wenn das Abtastorgan nur um den Bruchteil einer Teilungseinheit von der radialen Bewegung abweicht.So you have a mechanical scanning of the weighing result by means of sliding contacts compared to the scale arranged increased scanning point provided that a switch to a causes a second, laterally offset scanning element. Since this raised sampling point is as large as a scale unit must be designed and this acts like a graduation unit, can thereby the desired accuracy in correction and scanning can never be fully achieved, if only because the scanning width has to be chosen too large. There is also the Possibility of receiving false prints at the intersection of the decade, even if the scanner deviates from the radial movement by only a fraction of a division unit.
Bei einer anderen Waage hat man für jede Dekade einen besonderen Korrekturpunkt, insbesondere auch für jede Dekade ein besonderes AbtastorganWith other scales you have a special correction point for every decade, especially also a special scanning organ for each decade
