Description

Elektromagnet zum Erfassen von Blechen, Eisenplatten od. dgl. Das Patent 762 812 betrifft einen Elektromagnet zum Erfassen von Blechen, Eisenplatten od. dgl., der in der Weise ausgestaltet ist, daß an den Magnetpolen bzw. Polschuhen Streifen aus unmagnetischem Werkstoff zur Verhinderung des Klebens der anzuhebenden Bleche angeordnet sind, die als Abstandhalter über die Polflächen hinausragen.Electromagnet for detecting metal sheets, iron plates or the like Patent 762 812 relates to an electromagnet for detecting metal sheets, iron plates Od. Like. Which is designed in such a way that on the magnetic poles or pole pieces Strips made of non-magnetic material to prevent sticking of the items to be lifted Plates are arranged, which protrude as a spacer on the pole faces.

Gemäß der Erfindung werden derartige Elektromagnete dadurch weiter ausgestaltet, daß man die zur Verhinderung des Klebens dienenden, an den Magnetpolen bzw. an den Polschuhen angeordneten Streifen, die als Abstandhalter über die Polflächen hinausragen, verstellbar ausführt.According to the invention, such electromagnets are thereby further designed that one is used to prevent sticking to the magnetic poles or strips arranged on the pole pieces, which act as spacers over the pole faces protrude, executes adjustable.

Die Abstandhalter sind zweckmäßig in der Weise verstellbar, daß die Abstandhalterflächen parallel zu den Polschuhflächen verstellbar sind, d. h. daß der Abstand zwischen den Abstandhalterflächen einerseits und den Polflächen andererseits vergrößerbar oder verringerbar ist.The spacers are expediently adjustable in such a way that the Spacer surfaces are adjustable parallel to the pole shoe surfaces, d. H. that the distance between the spacer surfaces on the one hand and the pole surfaces on the other can be increased or decreased.

Eine derartige Ausbildung von Elektromagneten bietet den Vorteil, daß man die Menge der anzuhebenden Körper durch Bemessung des Abstandes der Abstandhalter in weitesten Grenzen genau einstellen kann. Dies ist - besonders nützlich für Elektromagnete, die zum Anheben, Sortieren oder Transportieren von Blechen verschiedener Größe dienen. Dies gilt namentlich auch für Elektromagnete, die zur Handhabung von Ständer- oder Läuferblechen für elektrische Maschinen dienen. Hier tritt nämlich die Aufgabe auf, daß man beispielsweise beim Stanzen von Ständer- oder Läuferblechen stets nur ein Blech in die Stanzmaschine einführen darf. Würden versehentlich zwei Bleche der Stanzmaschine zugeführt, so würden mehr oder weniger erhebliche Betriebsstörungen die Folge sein. Hinzu kommt noch, daß die von den Elektromagneten anzuziehenden und zu transportierenden Bleche verschieden stark und verschieden schwer sind. Allen den durch die vorerwähnten Gesichtspunkte gegebenen Aufgaben wird der neue Elektromagnet in vollstem Umfang gerecht, so daß er eine wesentliche Vereinfachung und Bereicherung der einschlägigen Technik bringt.Such a design of electromagnets offers the advantage that you can determine the amount of body to be lifted by measuring the distance between the spacers Set exactly within the broadest limits can. This is - special useful for electromagnets used for lifting, sorting or transporting Trays of different sizes are used. This also applies in particular to electromagnets, which are used to handle stator or rotor sheets for electrical machines. This is where the task arises, for example when punching uprights or rotor sheets can only insert one sheet into the punching machine. Would accidentally fed two metal sheets to the punching machine, more or less This could result in significant operational disruptions. In addition, that of the electromagnet to be attracted and to be transported sheets of different strengths and different are difficult. All the tasks given by the aforementioned points of view the new electromagnet does justice to the fullest extent, so that it is an essential Simplification and enrichment of the relevant technology brings.
