Abstract

Die Fördervorrichtung weist einen stromgesteuerten Motor, ein diesem nachgeschaltetes Getriebe zum Umsetzen der rotatorischen Rotorbewegung in eine translatorische Hubbewegung auf sowie eine davon angetriebene oszillierende Arbeitsmaschine. Der Motor wird von einer elektronischen Steuerung angesteuert, wobei der dem Motor zugeführte Strom (6 oder 7) entsprechend derzu erwartenden Motorbelastung in Abhängigkeit der Hubstellung der Arbeitsmaschine begrenzt wird. Hierdurch wird einerseits der Wirkungsgrad der Maschine erhöht und zudem eine unnötige thermische Belastung des Motors vermieden (Figur 3).

Figure 00000001
The conveying device has a current-controlled motor, a downstream of this transmission for converting the rotary rotor movement in a translational lifting movement and an oscillating driven working machine. The engine is driven by an electronic control whereby the current supplied to the engine (6 or 7) is limited in accordance with the expected engine load depending on the lift position of the work machine. In this way, on the one hand, the efficiency of the machine is increased and, moreover, an unnecessary thermal load on the engine is avoided (FIG. 3).
