Description
Die Erfindung betrifft eine Maschine zum Reinigen, Schleifen und Polieren von Gegenständen mit in einem flüssigen oder gasförmigen Trägermedium magnetisch bewegten Teilchen, mit einer Einrichtung zum Erzeugen eines elektromagnetischen Drehfeldes, die vier kreisförmig und sich paarweise gegenüberliegend angeordnete Spulen aufweist, welche von zwei ungleichphasigen Wechselstromquellen gespeist sind, und mit einem Behälter zur Aufnahme der magnetischen Teilchen und des Trägermediums.The invention relates to a machine for cleaning, grinding and polishing objects in one liquid or gaseous carrier medium magnetically moving particles, with a device for generating an electromagnetic rotating field, the four arranged in a circle and opposite one another in pairs Has coils, which are fed by two out of phase AC sources, and with one Container to hold the magnetic particles and the carrier medium.
Eine derartige Maschine ist aus der US-PS 27 35 232 bekanntgeworden. Mit der Maschine wird ein magnetisches Drehfeld erzeugt, das magnetisierbare Teilchen zu einer Bewegung in kleinen kreis- oder spiralförmigen Bahnen veranlaßt Der dabei auftretende Reinigungseffekt ist bei sonst gleichen Ausgangsbedingungen im wesentlichen nur von der Zeit abhängig, während der die zu reinigenden Gegenstände in der Maschine behandelt werden. Die mit der bekannten Maschine für die Reinigung aufzuwendenden Zeiten hüben sich jedoch bei hohen Ansprüchen an den Reinheitsgrad als zu lang erwiesen.Such a machine is known from US Pat. No. 2,735,232. With the machine becomes a magnetic Rotating field creates the magnetizable particle to move in small circular or spiral-shaped The cleaning effect that occurs is in the case of otherwise the same initial conditions essentially only depends on the time during which the items to be cleaned are in the machine be treated. The times required for cleaning with the known machine increase however, when the demands on the degree of purity are high, it has proven to be too long.
Um die Reinigungszeiten zu verkürzen, bedarf es einer Maschine, mit der je Zeiteinheit ein größerer Reinigungseffekt erzielbar bzw. mehr Schmutz von den Gegenständen entfernbar ist. Es ist daher Aufgabe der Erfindung, bei einer Maschine der eingangs genannten Art die Anordnung der Spulen derart zu ändern, daß die magnetisierbarer! Teilchen auf die zu reinigenden Oberflächen mit höherer Intensität auftreffen.In order to shorten the cleaning times, a machine is required with which a larger one per unit of time Cleaning effect can be achieved or more dirt can be removed from the objects. It is therefore the task of Invention to change the arrangement of the coils in a machine of the type mentioned in such a way that the more magnetizable! Particles hit the surfaces to be cleaned with higher intensity.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die vier Spulen sich gegenseitig überlappend angeordnet sind.According to the invention, this object is achieved in that the four coils overlap one another are arranged.
Durch die Erfindung wird erreicht, daß je Zeiteinheit
der noch auf den Gegenständen verbleibende Restschmutzanteil erheblich verringert wird. Die für die
Reinigung erforderliche Zeit wird gegenüber dem Stand der Technik etwa auf die Hälfte herabgesetzt
Außerdem ist der Reinheitsgrad höher, als er mit denWhat is achieved by the invention is that, per unit of time, the proportion of residual dirt still remaining on the objects is considerably reduced. The time required for cleaning is reduced by about half compared to the prior art
In addition, the degree of purity is higher than with the
S Vorrirhtungen nach dem Stand der Technik bisher erreichbar war. Schließlich kann eine Anzahl von Gegenständen in nur einem Reinigungsdurchgang mit ungewöhnlicher Gleichmäßigkeit zwischen den Gegenständen untereinander gesäubert werden.S state-of-the-art equipment was previously achievable. Finally, a number of Items in just one cleaning pass with unusual uniformity between items be cleaned from each other.
ίο Nachfolgend wird eine bevorzugte Ausführungsform der Erfindung anhand der Zeichnung näher beschrieben. Dabei zeigt dieίο The following is a preferred embodiment the invention described in more detail with reference to the drawing. The
Fig. 1 die Maschine mit der erfindungsgemäßen Anordnung der Spulen im Grundriß undFig. 1 shows the machine with the arrangement of the coils according to the invention in plan and
Fig.2 den verkleinert dargestellten Schnitt 2-2 aus Fig. 1.2 shows the section 2-2 shown on a reduced scale Fig. 1.
Die vorzugsweise zum Reinigen, Schleifen und Polieren eingesetzte Maschine besitzt eine Einrichtung zur Erzeugung eines magnetischen Drehfeldes und weist vier einander überlappende Spulen oder Wicklungen aus isoliertem Draht in einer kreisförmigen Anordnung gegenüberliegender Paare auf, die aus zwei ungleichph&sigen Wechselstromquellen so gespeist sind, daß gegenüberliegende Spulen gleichphasig, aber magnetisch entgegengesetzt polarisiert sind.The machine, which is preferably used for cleaning, grinding and polishing, has a device for generating a rotating magnetic field and has four overlapping coils or windings of insulated wire in a circular array of opposing pairs made up of two uneven-phase alternating current sources are fed in such a way that that opposite coils are in phase, but magnetically oppositely polarized.
Eine derartige Maschine ist in den Fig. 1 und 2 gezeigt, bei der das Paar gegenüberliegender Spulen 30a, 30b um einen zylindrischen Behälter 32 hemm angeordnet und von einem Paar gegenüberliegender Spulen 31a, 316 so umgeben ist, daß die aneinanderstoßenden Enden der äußeren Spulen 31a, 31 £> im Bereich der Mitten der inneren Spulen 30a, 30b liegen und sich so eine überlappende Anordnung einstellt Die inneren Spulen 30a, 30Zj werden gemeinsam aus der ersten Wechselstromquelle so gespeist, daß sie jeweils entgegengesetzt magnetisch gepolt sind. Entsprechend gemeinsam speist die zweite Wechselstromquelle die äußeren Spulen 31a, 31 i> so, daß auch sie magnetisch entgegengesetzt gepolt sind. Dabei dürfen die die Spulenpaare speisenden Wechselströme nicht die gleiche Phase aufweisen.One such machine is shown in Figs. 1 and 2 in which the pair of opposing coils 30a, 30b are disposed around a cylindrical container 32 and are surrounded by a pair of opposing coils 31a, 316 so that the abutting ends of the outer coils 31a , 31 £> lie in the area of the centers of the inner coils 30a, 30b and an overlapping arrangement is established. Correspondingly, the second alternating current source jointly feeds the outer coils 31a, 31i> in such a way that they are also magnetically oppositely polarized. The alternating currents feeding the coil pairs must not have the same phase.
In der erfindungsgemäßen Maschine werden magnetische Teilchen verwendet, die in einem gasförmigen oder flüssigen Trägermedium vorliegen. Derartige Teilchen bestehen beispielsweise aus y-Eisenoxid (Fe2O3), hartem Bariumferrit (BaO . 6Fe2O3), teilchenförmigen Aluminium-Nickel-Kobalt-Legierungen oder deren Mischungen.In the machine according to the invention, magnetic particles are used which are present in a gaseous or liquid carrier medium. Such particles consist, for example, of γ-iron oxide (Fe 2 O 3 ), hard barium ferrite (BaO. 6Fe 2 O 3 ), particulate aluminum-nickel-cobalt alloys or mixtures thereof.
erreicht man vorzugsweise, indem man den zu reinigenden Gegenstand und das Trägermedium mit den magnetischen Teilchen sowie gegebenenfalls Schleifteilchen und Reinigungsmittel in den (nichtmagnetischen) Behälter 32 innerhalb des Drehfeldes einbringt.is preferably achieved by having the object to be cleaned and the carrier medium with the magnetic particles and optionally abrasive particles and cleaning agents in the (non-magnetic) Brings container 32 within the rotating field.
