An energy management control apparatus for a molding machine that includes a first electrically-driven prime mover configured to drive at least a first molding machine device, and a second electrically-driven prime mover configured to drive at least a second molding machine device, includes a common DC link configured to provide DC energy to the first electrically-driven prime mover and to the second electrically-driven prime mover. A slave axis is configured to supply and absorb energy from to/from the common DC link. A machine controller is configured to (i) communicate with the first electrically-driven prime mover, the second electrically-driven prime mover, the common DC link, and the slave axis, (ii) cause the slave axis to supply energy to the common DC link in response to input from at least one of the first electrically-driven prime mover and the second electrically-driven prime mover, and (iii) cause the slave axis to absorb energy from the common DC link in response to input from at least one of the first electrically-driven prime mover and the second electrically-driven prime mover.
摘要:
Die Erfindung betrifft einen Antrieb mit elektrischer Leistungssteuerung für Maschinen, die zyklisch Bewegungen mit hohen Beschleunigungen fahren müssen. Ein Elektromotor (2) treibt eine Pumpe (3), welche wiederum direkt mit einem Zylinder (10, 11) verbunden ist. Dieser Anordnung wird ein System von Druckspeichern (8, 9) und Ventilen aufgeschaltet, die dem System die Eigenschaft eines Oszillators geben. Die Beschleunigungskräfte bei einer zyklischen Bewegung nahe an der Resonanz werden dann weitgehend von den Druckspeichern (8, 9) und den damit verbundenen Zylindern (10, 11) geleistet. Dies führt zu einer Entlastung des Elektromotors (2) und ermöglicht geringere Leistungen auf der Maschine zu installieren oder aber bei gleicher Leistung kürzere Zykluszeiten der Maschine zu realisieren.

摘要:
An injection molding machine is provided that is capable of operating a load connected between a power source and a power regenerating part even when power failure of the power source occurs. The injection molding machine includes a motor (e.g., servo motors 11, 24, 42, and 44), a drive part (e.g., inverter circuits 51-54) that drives the motor, the power regenerating part (e.g., converter circuit 80) that regenerates electric power to the power source, and the load (e.g., load 110 including controller 26) that is connected between the power source and the power regenerating part. The power regenerating part is configured to supply operating power for operating the load when power failure of the power source occurs.
