Description

Die Erfindung betrifft eine Anordnung zur Er- zeugung von; Steuerwerten für Kantenregelung, insbesondere für Siabdaufragelungen von Papier- maschinen, mit einem waagebialke-niarrmig gelagerten, Meßgefäß, das so ausgebildet isst, d'aß es. die ihm in der Normalstellung des Siobes von einem vorn der Siebkantea gesteuerten Flüss;igkeitsstrafhl in einer Zeiteinheit zufließende Wassermengen unter Auf- rechterhaltung des. Fiüssigkeits,spiegel:s wieder ab, laufen läßt. Die bekannten Anordnungen: dieser Art haben jedoch insbesondere den Nachteil, dali sie leicht zu Überregelungen; führen. Die Erfindung bezweckt; die Nachteiste der be- kannten Einrichtungen dieser Art zu: vermeiden, und zwar dadurch, d.alß die Achse des. Waage- balkens der MeLßgefäßlagerung mit einem, Potentio- m:eter gekoppelt ist. Dadurch kann der Regelvor- gang wesentlich präziser durchgeführt werdent, in- de,m- in den Regelvorgang. selbst mit einfachsten Mitteln ein Rückführwert eingeführt wird, der ein Überregeln vermeidet. Mit rein mechanischen Gliedern dagegen, ist beüi deramtigen Regelednrich- tungen, ein Überregeln und damit ein Pendeln des Siebes kaum zu vermeiden. Die erfindungsgemäße Anordnung zeichnet sich ferner durch einfachen und mechanisch stabilen Aufbau, aus, ivoibei die empfindlichen Teile, z. B. d,asi Potentiomeier, in Gehäusen geschützt werden, können;, durch die lediglich: die Leitungsanschlüsse und eine Welle zur Verstellung des: Potentiometer- abgriffes durchgeführt werden müssen. Air Hand der Zeichnung wird, ein Ausführungs.- beispiel nach der Erfindung erläutert. Die Figur -zeigt ein, Sieb, i,. das; sich in einge- zeichneter Pfeilrichtung weiterbewegt. Air der Siebkante ist eine Flüssigkeitsdüse a angeordnet, deren Flüssigkeitsstrahl durch die Siebkante ge- steu;esrt wird. In der Normalstellung fließt der hailbe Flüssigkeitsstrahl in, das waagebalken artig gelagerte Meßgefä,ß 4, das mit einer Öffnung 5 ver- sehen ist, die so- mit dler Flüssigkeitsdüse abge- stimmt ist, daß in dieser Stellung die zulaufende Waissermenge wider abfließt. Je nachdem, in wel- cher Richtung die Siebkante vom: detn Normaallauf abweicht, wird mehr oder weniger Flüssigkeit in den Auffangbehälter 4 gelangen und damit durch das Gegengewicht 6 der Waagebalken 3 aus seiner Nullstellung herausbewegt. Dadurch wird der vorzugsweise starr mit seiner Achse 'gekoppelte Potentiometerabgriff 7 das. Portentiometers 8 aus der Normailstellung herausbewegt, und es. wird: in der Steuerwicklung 9, z. B. auf einem Relais eines an sich bekannten Zeigerreglers, ein Steuerwert für einen VersteUmotor io. der Lauf- und Reguher- walze, i i. gegeben. Der Sollwert für die Normal- stellung des Meßgefäßes.4 kann. durch Einstellen, das Gegenpoitentiometerabgriffes 12 bestimmt werden. The invention relates to an arrangement for procreation of; Control values for edge control, especially for Siabdaufragelungen of paper machines, with a horizontal ax niarrmig bearings, Measuring vessel that eats so designed that it eats. the him in the normal position of the Siobes from a front of the Siebkantea controlled liquid stream in one Time unit of inflowing water volumes preservation of the liquid, mirror: s again, runs. The known arrangements: have this type however, the particular disadvantage is that they are light to overregulations; to lead. The invention aims; the night bar of the known facilities of this type to: avoid, namely by the fact that the axis of the. bar of the measuring vessel storage with a potentiometer m: eter is coupled. This allows the rule can be carried out much more precisely, in de, m- in the control process. even with the simplest Means a feedback value is introduced that represents a Avoids overriding. With purely mechanical Dividing, on the other hand, is overregulation and thus a fluctuation of the Sieves can hardly be avoided. The arrangement according to the invention is distinguished also by simple and mechanically stable Structure, from, ivoibei the sensitive parts, e.g. B. d, asi potentiometer eggs, to be protected in housings, can; through which only: the line connections and a shaft for adjusting the: potentiometer tap must be carried out. Air hand of the drawing is made, an execution. example explained according to the invention. The figure shows a, sieve, i ,. the; get into arrow direction moves on. Air the Sieve edge is arranged a liquid nozzle a, whose liquid jet is through the sieve edge control; esrt is. In the normal position the flows hailbe jet of liquid in, the horizontal beam-like stored measuring vessel, ß 4, which is provided with an opening 5 can be seen that the liquid nozzle is shut off it is true that in this position the tapered Waisser amount flows off again. Depending on the in the direction of the sieve edge from the normal run deviates, more or less fluid is in reach the collecting container 4 and thus through the counterweight 6 of the balance beam 3 from its Zero position moved out. This will make the preferably rigidly coupled with its axis' Potentiometer tap 7 the. Portentiometer 8 off the normal position moved out, and it. is in the control winding 9, e.g. B. on a relay one known pointer regulator, a control value for an VersteUmotor io. the running and regulating roller, i i. given. The setpoint for normal position of the measuring vessel. 4 can. by setting, the Gegenpoitentiometerabgriffes 12 is determined will.
