Power failure detection unit 211 is for being used to judge the function important document that whether interrupts the supply of the alternating electromotive force of control part 20 or electric power converter section 30; For example according to the output of ac voltage detection circuit 24; Judge have or not in the AC power 10 have a power failure (comprising instantaneous power failure) and AC power 10 in have or not and remove and have a power failure (for example, beginning based on urgent with exchanging the power supply for preparing power supply.) etc.

Can continue moulding calculating part actuation time 212 for be used to calculate do not accept from the supply of the alternating electromotive force of external power source just can proceed the time that the moulding of injection (mo(u)lding) machine moves (below be called " can continue moulding actuation time ".) the function important document; For example; When being judged to be through power failure detection unit 211 when interrupting from the supply of the alternating electromotive force of AC power 10; According to the information of the electric power storage state of 33 pairs of controllers of relevant the 2nd electrical storage device 21 output, calculate continued moulding actuation time based on the electric power of the 2nd electrical storage device 33.

And; Moulding calculating part actuation time 212 can be continued and the consumes electric power amount of per 1 moulding circulation can be derived according to the output of make-up machine sensor 50; And, calculate continued moulding actuation time based on the electric power of the 2nd electrical storage device 33 according to the consumes electric power amount of this per 1 moulding circulation and the information of the electric power storage state of relevant the 2nd electrical storage device 33.

In addition; Can continue moulding calculating part actuation time 212 and need not receive information from the 2nd electrical storage device 33 and infer the electric power storage state (for example being estimated as full electric power storage state) of the 2nd electrical storage device 33, also can be according to the continued moulding actuation time of this electric power storage state computation of inferring based on the electric power of the 2nd electrical storage device 33.

Could continue moulding action detection unit 213 for being used to judge the function important document that not accept to proceed the moulding action of injection (mo(u)lding) machine from the supply of the alternating electromotive force of external power source; For example; When being judged to be through power failure detection unit 211 when interrupting from the supply of the alternating electromotive force of AC power 10; Detected value according to 21 outputs of 51 pairs of controllers of peripheral sensors; Judge whether one or more ancillary equipment are in the state that is fit to continue the moulding action separately, and judge that according to these judged results could continue moulding moves.

At this moment, when one or more ancillary equipment are in can't duty the time or can't receive the output from one or more peripheral sensors 51, could continue moulding action detection unit 213 and be judged to be and to continue the moulding action.

And; Could continue moulding action detection unit 213 also can take place to beginning (to be the predefined time, below to be called " prepare power supply switching time " with the time till the power supply that exchanges the preparation power supply based on urgent according to the continued moulding actuation time that can continue that moulding calculating part actuation time 212 calculates and power failure from AC power 10.), judgement could continue the moulding action.

At this moment; When continuing moulding actuation time to be preparation power supply switching time when above, could continue moulding action detection unit 213 and be judged to be and to continue the moulding action, on the other hand; Be shorter than the preparation power supply during switching time actuation time when continuing moulding, be judged to be and continue the moulding action.

And, irrelevant with the length that can continue moulding actuation time when not setting the preparation power supply during switching time, could continue moulding action detection unit 213 decidables for continuing the moulding action.

Moulding action stops detection unit 214 and does not accept the function important document that stops from the moulding action that the supply of the alternating electromotive force of external power source is proceeded for being used to judge whether make; For example; Although but when not recovering the power supply based on external power source, be judged to be and stop its moulding action through preparation power supply switching time.

And although do not recover the power supply based on external power source switching time through the preparation power supply, and the storage voltage of the 2nd electrical storage device 33 is when predetermined voltage is following, and the moulding action stops detection unit 214 decidables for stopping its moulding action.

Stop mode selection portion 215 is for being used for through continuing that moulding action detection unit 213 is judged to be can't continue the moulding action time or when stopping detection unit 214 and be judged to be the moulding action that should stop to proceed through the moulding action, selecting the function important document of the stop mode of injection (mo(u)lding) machine.

" stop mode " is the method for the injection (mo(u)lding) machine that is used for stopping to move, for example has " stop mode after the die sinking " that stop injection (mo(u)lding) machine after " the back stop mode is accomplished in pressurize " that stop injection (mo(u)lding) machine after " 1 the circulation stop mode " that stop injection (mo(u)lding) machine after the moulding circulation in accomplishing current executed, the pressurize operation in the circulation of the moulding in accomplishing current executed and the moulding in the accomplishing current executed die sinking operation in circulating etc.

Stop mode selection portion 215 grasps the present situation of injection (mo(u)lding) machine according to the output of make-up machine sensor 50, selects the stop mode of suitable its present situation, and carries out the stop mode of having selected.

Particularly; 215 pairs of moulding control parts of stop mode selection portion, 210 its selection results of output; The moulding control part 210 that receives this selection result generates and the corresponding timing controling signal of this stop mode of having selected, stops the moulding action based on this injection (mo(u)lding) machine through the timing controling signal that one or more inverter circuits 34 are exported these generations separately.

Then, the flow process that control is handled during based on the power failure of building control system SYS with reference to 3 couples in figure describes.In addition, Fig. 3 controls the flow chart of the flow process of handling when this has a power failure for expression, and control was handled when building control system SYS repeated this power failure with predetermined period.
