Description
Waage mit elektrischer Lastausgleichsvorrichtung Die Erfindtiri- betrifft eine Waage, bei (1-er der Lastausgleich durch Regelung der Stärke eines elektrischen Stromes erfolgt, der durch eine einen am Waagebalken befestigten Magnetkern anziehende Spule fließt.Scales with electrical load balancing device The invention relates to a balance, at (1-er the load balancing by regulating the strength of an electrical Current takes place, which is attracted by a magnetic core attached to the balance beam Coil flows.
Bei den bekannten Waagen dieser Art läßt sich zwar unmittelbar an der Skala. des elektrischen Anzeigeinstrumentes (las Gewicht der aufgelegten Last ablesen. Außerdem können s s ie a uf ein bestimmtes Gewicht, auf das (las aufgelegte Gut durch eine besondere Behandlung, z. B. durch Zuführen von. Feuchtigkeit, vor Ablieferung gebracht @yerden muß, vorher von Hand eingestellt «-erden. Da jedoch bei diesen bekannten Waagen nur eine elektrische Lastausgleichs- und Regelvorrichtung vorlanden ist, kann die Gewichtszunahme nicht unmittelbar für sich, sondern erst nach Errnittlun g des Endgewichtes durch Rechnung eingestellt werden.In the case of the known scales of this type, it is possible to start immediately the scale. of the electrical display instrument (read the weight of the applied load read off. You can also rely on a certain weight to which the (read Good by a special treatment, e.g. B. by supplying. Moisture, before Delivery brought @yerden must, previously set by hand «-erden. However, since in these known scales only one electrical load balancing and control device is landing, the weight gain cannot be immediate, but only after the final weight has been calculated by means of an invoice.
Gemäß der Erfindung soll nun ohne Rechnung die Gewichtszunahme des aufgelegten Gutes- durch eine besondere Behandlung bei einer Waage der eingangs genannten Art einstellbar sein. Dies 'wird erfindungsgemäß dadurch erreicht, daß konzentrisch zu (leg nach (lein Auflegen der Last zum Lastausgleich dienenden Spule eine in einem besonderen Stromkreis liegende Spule vorgesehen ist, deren Anziehungskraft auf den am Waagebalken befestigten Magnetkern mittels eines besonderen Widerstandes auf eine bestimmte, durch eine- besondere Behandlung des aufgelegten Gutes zu erzielende Gewichtszunahme 1)ei Beginn der @\'ügunri eingestellt wird.According to the invention, the weight increase of the placed goods- through a special treatment on a scale of the initially mentioned type be adjustable. This' is achieved according to the invention in that concentric to a coil lying in a special circuit is provided, whose attractive force on the magnetic core attached to the balance beam by means of a special resistor to a certain, to be achieved by a special treatment of the placed goods Weight gain 1) at the beginning of the @ \ 'ügunri is stopped.
Die Einrichtung ist in der Zeichnung schemu,tisch dargestellt. Der.: Waagebalken ff,' t r. *igt an der einen Seite innerhalb eines für die besondere Behandlung des Gutes vorgesehenenRaumes einen Korb l(, der mit,einer kleineren Probe des Gutes gefüllt ist. Die Lageruni des Waagebalkens liegt in der Außenit-and des Räuines, ' die mit t- bez.eiclrnet ist. Aullerliall) des Rauries liegt die andere Hälfte des Waagebalkens finit der elektrischen Lastausgleichs- und Regelvorrichtung. Diese besteht aus einem am Waagebalken befestigten. Magnetkern 111 und zwei Spulen T und 11, welche von unabhängigen Strömen durchflossen werden. In dem Stromkreis der Spule I liegt ein Widerstand U',, mit dessen Hilfe die Anziehungsstärke auf den 'Magnetkern beim Auflegen der Last so eingestellt werden kann, daß der Gleichgewichtszustand erreicht ist. Der Widerstand lV_ (leg Spule Il hat währenddessen auf o gestanden. je nachdem die Spule II mehr oller weniger stark erregt wird, inuß die anziehende Wirkung auf den Magnetkern !1! eine stärkere oder geringere sein. An dem Widerstand IV. lüßt sich die Kraft der Anziehung gewichtsmäßig in Gramm ablesen. Je nachdem nun an der Gradeinteilung des Widerstandes IV., die Gewichtshöhe eingestellt wird, kann die -Menge, tim die (las im Korb enthaltene Gut iirt Gewicht gesteigert werden soll, vorher festgelegt werden.The device is shown schematically in the drawing. Der .: Balance beam ff, 't r. * IGT on the one side within one of the special treatment of the material pre see space a basket l (which is filled with, a smaller sample of the material. The Lageruni of the balance beam is in the Außenit-and the Räuines' with t- inscribed .eiclrnet is. Aullerliall) des Rauries, the other half of the balance beam is finite to the electrical load balancing and control device. This consists of one attached to the balance beam. Magnetic core 111 and two coils T and 11, through which independent currents flow. In the circuit of the coil I there is a resistance U ', with the aid of which the strength of attraction on the magnetic core when the load is applied can be adjusted so that the equilibrium state is reached. The resistance IV_ (leg coil II has meanwhile been at o. Depending on whether the coil II is excited more or less strongly, the attractive effect on the magnetic core must be greater or lesser. The force can be determined at the resistor IV The weight of the attraction can be read off in grams, depending on the weight height being set on the graduation of the resistance IV.
