Description

Elektrischer Antrieb für Arbeitsmaschinen mit hin und her gehender Bewegung Es ist ein elektrischer Antrieb für Arbeitsmaschinen mit hin und her gehender Bewegung bekannt, bei dem sowohl für den Arbeitsgang wie für den Rücklauf je ein besonderer 'Motor vorgesehen ist.Electric drive for work machines with reciprocating Movement It is an electric drive for working machines with reciprocating Movement known, in which one each for the operation as for the return special 'engine is provided.

Die Umsteuerung eines Antriebes einer Maschine mit hin und her gehender Bewegung erfordert aber bekanntlich eine ganz erhebliche Umsteuerungs- und Beschleunigungsleistung. Diese wächst um so höher an, je geringer die Verlustzeiten einer solchen Maschine werden sollen. Soll dieser Forderung Genüge geleistet werden, so müssen die Antriebsmotoren stark bemessen werden. Hierdurch würde aber eine unerwünschte Erhöhung des Preises der Maschine eintreten. Gemäß der Erfindung werden deshalb zur Deckung der LTmsteuerungs- und Beschleunigungsarbeit am Hubende beide Motoren zum Antrieb des zu bewegenden Teiles verwendet. Der für (las betreffende Arbeitsspiel nicht weiter in Frage kommende Motor wird dann abgeschaltet.The reversal of a drive of a machine with going back and forth However, as is well known, movement requires a considerable amount of reversing and acceleration. This increases the higher the shorter the downtime of such a machine should be. If this requirement is to be met, the drive motors must strong. This would, however, lead to an undesirable increase in the price enter the machine. According to the invention, therefore, to cover the LTmsteuerungs- and acceleration work at the end of the stroke, both motors to drive the one to be moved Part used. The one that is no longer in question for (read the relevant work cycle The motor is then switched off.

Da nun die Rücklaufgeschwindigkeit des Tisches größer ist als die Arbeitsgeschwindigkeit und man infolgedessen für den Rücklauf einen 'Motor mit höherer Betriebsdrehzahl wählen wird, so würde der Vorlaufmotor, falls er zur Unterstützung des Rücklaufmotors herangezogen wird, über seine Betriebsdrehzahl hinaus durch den Rücklaufinotor beschleunigt werden. Dieser unerwünschte Vorgang wird gemäß der Erfindung dadurch vermieden, daß der Motor mit der geringeren Betriebsdrehzahl abgeschaltet wird, wenn diese erreiqkt ist. Man kann zu diesem Zwecke beispielsweise einen der bekannten Fliehkraftschalter verwenden.Since now the return speed of the table is greater than that Working speed and as a result you have a motor with a higher speed for the return Operating speed is selected, so would the lead motor if it were to assist of the reverse motor is used, beyond its operating speed by the Return rotor can be accelerated. This undesirable process is carried out in accordance with the invention thereby avoided that the motor is switched off at the lower operating speed when this is achieved. For this purpose, for example, one of the use known centrifugal switch.
