Abstract

The device is intended for a pattern-device on knitting-machines. A non-controlled permanent-magnetic holding-pole has its surface at the control-point reduced or it has a clearance at the back so as to form an air-gap, which leads to a reduction of the holding-field, when a voltage is applied at the control-winding of the control-coil. In this way, the action of the reduced throw-off capacity of the control magnet is intensified.

Abwurfstelle an SteuermagnetDrop point on control magnet

Abwurfstelle an Steuermagnetsystem für eine Mustereinrichtung an Strickmaschinen.Drop point on control magnet system for a sample device Knitting machines.

Diese permanentmagnetisch geschwächte Steuerstelle ermöglicht einen exakten Abwurf der Steuerplatinen vom Steuermagnet.This permanently magnetically weakened control point enables one exact ejection of the control boards from the control magnet.

Es sind äteuermagnete bekannt US-P 3 365 916, ΠΓ-OS 1 585 2o8, OS 1 635 9oo, DP 1 226 237, bei welchen die Haltepole auf die gesamte Haftlähge eine planparallele Ebene zur Gleitleiste und somit ungeschwächte Haftflächen bilden.There are Äteuermagnete known US-P 3 365 916, ΠΓ-OS 1 585 2o8, OS 1 635 9oo, DP 1 226 237, in which the holding poles on the entire Haftlähge a plane parallel to the sliding strip and thus not weakened Form adhesive surfaces.

Diese planparallele Haftfläche führt zu einer gleichbleibenden permanentmagnetischen Haftkraft über den gesamten Steuermagnet, auch im Bereich der Steuerstelle. Da die Induktivität nicht beliebig vergrößert werden kann, ist die Zuverlässigkeit dieser bekannten Steuermagneten beim Abwerfen der Platinen nicht sehr groß.This plane-parallel adhesive surface leads to a constant permanent magnetic one Holding force over the entire control magnet, also in the area of the control unit. Because the inductance is not increased arbitrarily can be, is the reliability of these known control magnets not very big when ejecting the boards.

Der Erfindung liegt die Aufgabe zugrunde, die Wirkung der geschwächten Abwurfkapazität des Steuermagneten zu vergrößern.The invention is based on the object, the effect of the weakened To increase the throwing capacity of the control magnet.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der nicht steuerbare permanentmagnetische Haltepol im Bereich der Steuerstelle durch verkleinern oder zurücknehmen der Haftfläche geschwächt wird, was verstärkt zum Abfallen des Haltefeldes führt, wenn an der Steuerwicklung der Steuerspule eine Spannung angelegt wird.This object is achieved according to the invention in that the non-controllable permanent magnetic holding pole is in the area of the control point is weakened by reducing or reducing the adhesive surface, which leads to the dropping of the holding field when on the control winding a voltage is applied to the control coil.

Die mit der Erfindung erzielten Vorteile bestehen besonders darin, daß die permanentmagnetischen Haltepole an der Abwurfstelle annähernd wirkungslos sind, so daß nur das umpolbare Feld des Steuermagneten das Halten oder Abwerfen der Steuerplatine verändern oder beeinflussen kann.The advantages achieved by the invention are in particular that the permanent magnetic holding poles at the release point are almost ineffective, so that only the reversible field of the control magnet Holding or throwing the control board can change or influence.

Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden im folgenden näher beschrieben.Embodiments of the invention are shown in the drawing and are described in more detail below.

Die Steuerseite des Magneten besteht aus permanentmagnetischen Haltepolen (1o, 1of und 11). Haltepol (11) ist im Bereich der Abwurfstelle (22) ausgenommen oder geschwächt. (Flg. 1 bis 6)The control side of the magnet consists of permanent magnetic holding poles (1o, 1o f and 11). The retaining pole (11) is cut out or weakened in the area of the release point (22). (Flg. 1 to 6)

Dieser Bereich wird magnetisch nur vom Steuerpol (21) überbrückt. Zwischen den beiden Haltepolen befinden sich planeben antimagnetische harte ßleltleisten (12), die jedoch den Haltepolen gegenüber nicht zurückgenommen sind und somit über die gesamte Haltelänge des Magneten plan sind.This area is only bridged magnetically by the control pole (21). Between The two retaining poles are flat, anti-magnetic, hard flanged strips (12), which, however, are not withdrawn from the holding poles and are therefore flat over the entire holding length of the magnet.
