Power supply management device and machine tool having the power-supply management device

Abstract

The present invention provides a power-supply management device which can efficiently connect and disconnect power supply to an electric-powered section, and a machine tool including the power-supply management device. The power-supply management device ( 101 ) detects a synchronization command of a control program, and compares an operation time of the electric-powered section between synchronizations in each control system which is a synchronization target by the synchronization command on the basis of the detected synchronization command. Then, the power-supply management device ( 101 ) disconnects the power supply to the electric-powered section belonging to the control system except the control system having the maximum operation time of the electric-powered section between the synchronizations, and restarts the power supply at the end of the synchronization in each control system.

         10 . A power-supply management device, comprising:
 a power-supply-connecting/disconnecting section configured to connect/disconnect power supply to a plurality of electric-powered sections of a machine tool, the plurality of electric-powered sections operating in processing of a material held by the machine tool, wherein   the power-supply connecting/disconnecting section is configured to disconnect power supply to each of the electric-powered sections during interruption or preparation of the processing of the material, and restart the power supply to each of the electric-powered sections at start or restart of the processing.   
     
     
         11 . A power-supply management device, comprising:
 a power-supply-connecting/disconnecting section configured to connect/disconnect power supply to a plurality of electric-powered sections of a machine tool, the plurality of electric-powered sections operating in processing of a material held by the machine tool, wherein   the power-supply connecting/disconnecting section is configured to disconnect power supply to each of the electric-powered sections during drawing up or editing of a processing control program for processing the material, and restart the power supply to each of the electric-powered sections at start or restart of the processing after the drawing up or the editing of the processing control program is completed.   
     
     
         12 . A machine tool comprising:
 a plurality of electric-powered sections operating in processing of a material; and   a power-supply management device configured to connect/disconnect power supply to the plurality of electric-powered sections, wherein   the power-supply management device according to  claim 10  is used for the power-supply management device.   
     
     
         13 . A machine tool comprising:
 a plurality of electric-powered sections operating in processing of a material; and   a power-supply management device configured to connect/disconnect power supply to the plurality of electric-powered sections, wherein   the power-supply management device according to  claim 11  is used for the power-supply management device.
