Embodiment 2:
Embodiment's 1 described injection machine that has this energy-saving control device comes the revolution of sense of control induction motor 60 with energy-saving control device 100, so just can realize the Energy Saving Control of injection machine 1.Induction motor 60 is driven by frequency variator, exerts oneself hour, and consumption electric power is just little.Exerting oneself of induction motor 60 can be represented by the formula.
L＝2π·T·N/6120···························(1)
Exerting oneself of L in the formula (Kw) expression induction motor 60,
The torque of T (kgfm) expression induction motor 60,
N (min
-1) expression induction motor 60 revolution
According to following formula,, just alleviate the consumption electric power of induction motor 60 as can be known at the revolution of the torque T of induction motor 60 timing by sense of control induction motor 60.That is to say, give the operating state of each actuator (oil cylinder or oil hydraulic motor) of injection machine 1, the revolution of a sense of control induction motor 60 is imported the pressure oil of necessary amount, so just can realize the Energy Saving Control of injection machine 1.
Described energy-saving control device 100 is to be made of frequency variator 101 and controller 110 etc.Herein, the suitable in the present invention motor control part of frequency variator 101.
Described controller 110, be equipped with the "on" position (operating state) that electromagnetic coil action detecting element 111 and motor revolution determination section 112. electromagnetic coil detecting elements 111 can detect each electromagnetic coil, this "on" position is sent in 112. enforcement states 1 of motor revolution determination section, electromagnetic coil action detecting element 111, by solenoid directional control valve action perceptron 120, receive on each electromagnetic coil of oil hydraulic circuit 30.
Described solenoid directional control valve action perceptron 120 is by full wave rectifier 121, and resistance 122 and optoelectronic isolator 123 etc. constitute (among Fig. 4, being that expression electromagnetic coil 34a connects solenoid directional control valve action perceptron 120).More particularly, full wave rectifier 121 is in parallel with electromagnetic coil 34a.Resistance 122 and full wave rectifier 121 and electromagnetic coil 34a (series connection) distribution that continues.Optoelectronic isolator 123 continues with the terminal of exerting oneself of full wave rectifier.The action detecting element 111 of the exert oneself terminal and the electromagnetic coil of optoelectronic isolator 123 continues.That is to say, solenoid directional control valve action perceptron 120, the operation voltage that electromagnetic coil 34a is added up will be changed to fixed VDC, this VDC is added on the optoelectronic isolator 123, electromagnetic coil action detecting element 111 can detect exerts oneself and transmits.
The above-mentioned injection machine that has energy-saving control device, the operation voltage of described electromagnetic coil has various voltages.For example, in Japan, three kinds of DC24V/AC100V and AC200V are arranged roughly.Therefore, electromagnetic coil action detecting element 111 when directly continuing, must be confirmed each operation voltage of adding up with electromagnetic coil (or to electromagnetic coil power supply distribution).But, by solenoid directional control valve action sense part 120, electromagnetic coil is moved detecting element 111 receive on the electromagnetic coil, just can omit the operation voltage affirmation operation that each electromagnetic coil is added up.Thus, just electromagnetic coil can be moved the operation that continues of detecting element 111 and electromagnetic coil becomes easy.Certainly, also electromagnetic coil can be moved detecting element 111 directly continues with each electromagnetic coil.
Motor revolution determination section 112 based on the "on" position (operating state) of each electromagnetic coil that is detected by electromagnetic coil action detecting element 111, decides the revolution of induction motor.More particularly, motor revolution determination section 112 for example has memory portion to chart shown in Figure 5, based on the result that detects of this chart and electromagnetic coil action detecting element 111, just can determine the revolution of induction motor 60.

The chart of described this Fig. 5 is to determine according to the kind of the resin of moulding.For example, for the kind (same ejaculation pressure) of same moulding, because the difference of the manufacturer of injection machine, the revolution of induction motor necessity also has difference.And for example, with the injection machine of machine, the ejaculation pressure of each kind also is different.Therefore to decide the necessary revolution of induction motor according to the kind of the resin of moulding.
Above-mentioned energy-saving control device, for example described, (1) of Fig. 5 is the electromagnetic coil 32a of expression solenoid directional control valve 32, the electromagnetic coil 34a of solenoid directional control valve 34 and the electromagnetic coil 35a of solenoid directional control valve 35 when operating state (when nozzle advances operation).In the induction motor hurdle of this Fig. 5 (1), for example the decision be 70% go into power the time, the electromagnetic coil 32a of solenoid directional control valve 32, when the electromagnetic coil 34a of solenoid directional control valve 34 and the electromagnetic coil 35a of solenoid directional control valve 35 are in operating state, by motor revolution determination section 112, the revolution of decision induction motor 60 is 70% of a rated revolution.
Described in each hurdle of chart of Fig. 5, have and plant the power method.For example, can make the chart identical, to motor revolution determination section 112 (controller 110) transmission information by the user with Fig. 5 chart.For example, the user can be in each hurdle of chart in the motor revolution determination section 112 (controller 110), directly into power.
In the described energy-saving control device, described induction motor 60 sends this revolution information to frequency variator 101 after determining revolutions by motor revolution determination section 112.Frequency variator 101 reaches for example to be connected by the electric power supply source 62 of source power supply supply with induction motor 60 and continues.This frequency variator 101, the alternating voltage that electric power supply source 62 is supplied with becomes VDC.So, this direct current is pressed with the alternating voltage that revolution information that motor revolution determination section 112 sends induction motor 60 to becomes corresponding frequency supplies with induction motor 60.Thus, induction motor 60, just the revolution that is determined by motor revolution determination section drives.Control device 100 shown in Figure 3 is exactly the control device of injection machine 1.
Described energy-saving control device, the described energy-saving control device 100 that is so constituted by electromagnetic coil action detecting element 111, detects the operating state of the electromagnetic coil of each solenoid directional control valve.Thus, just know the operating state of the actuator (oil cylinder or oil hydraulic motor) that each solenoid directional control valve is controlled.Based on the result that detects of electromagnetic coil action detecting element 111, just decide the revolution of induction motor 60 by motor revolution determination section 112, this revolution is just controlled by frequency variator 101.Thus, the dynamical state of injection machine 1 just can remove the revolution of driven induction motor 60 by the revolution that is fit to.So, to the oil hydraulic circuit 30 of existing injection machine 1, just control by the energy-saving control device of being installed 100, even if each main frame manufacturing firm has different programs, also can realize the energy-conservation chemical control system of injection machine 1.
Because electromagnetic coil action detecting element 111 has solenoid directional control valve action perceptron 120, that is to say, electromagnetic coil action detecting element 111 is connected with electromagnetic coil by solenoid directional control valve 120, so the operation that continues of electromagnetic coil action sense part 111 and electromagnetic coil is easy.
Chart (Fig. 5) with motor revolution determination section 112 is an example wherein just.For example, can indicate that the revolution of induction motor 60 is gone into power in the designation of each electromagnetic coil.And, when having the action of plural electromagnetic coil, the revolution of the induction motor that the designation of decision and each electromagnetic coil matches.
