In addition, the various operational condition value inputted from input unit 5 are stored in molding condition setting memory cell 11 in rewritable mode.As the project of the service condition corresponding with operational condition value, such as, except measure control condition, back suction controlled condition, injection controlled condition, mold closing controlled condition, die sinking controlled condition, spraying fire condition, on the basis showing the image shown in Fig. 3, also there are the working time etc. of the material feeding number " N " in step 2 described later, injection machine.
Forming technology control unit 12 is based on ready-made forming technology control program and the value that imposes a condition be stored in molding condition setting memory cell 11, with reference to from sensor group (the material feeding counting number unit 17 in each portion being arranged at injection machine, timing unit 18, temperature measurement unit 19, injection pressure measurement is with sensor 20 etc.) measurement information, and via the motor driver 21 carrying out FEEDBACK CONTROL as described driver bank 8, heater driver 22, fluidic actuator driver 23 grade and carry out the drived control of corresponding drive source, perform a series of automatic operation of shaping formed products, resin viscosity measurement pattern described later etc.

Resin viscosity computing unit 14 uses the actual measurement injection pressure force value (measured value of injection pressure measurement sensor 20) of injection speed one timing, utilizes calculating formula described later to calculate (mensuration) resin viscosity.Then, based on the viscosity of the molten resin calculated value and carry out the change of the design temperature of the heater 10 of the passage (ch) specified by thermostat unit 15.
In addition, display processing unit 16, according to the call signal of the display image desired by being produced by operator's input device, is made/control program based on ready-made display image, is made the display view data of the display mode of specifying.This view data made is passed on and is temporarily stored in not shown frame buffer, according to the instruction of display processing unit 16, the output of frame buffer is presented on the picture of display unit 6 as view data with the state shown in Fig. 3.
At this, the computational methods of the resin viscosity undertaken by resin viscosity computing unit 14 are described.Shear stress τ (Pa) setting viscosity as η (Pasec), if when shear rate is γ (sec-1), be expressed from the next,
τ=η × γ ... (1) formula
At this, in relation between the shear rate γ represented by (1) formula (being equivalent to the injection speed represented by the pace of screw rod 2 in the injection machine of coaxial screw) and viscosities il (viscosity of molten resin), namely, for the viscosity of resin, the situation of the behavior shown in Fig. 4 can be confirmed, if shear rate γ can be confirmed be in 10
1~ 10
5scope in, then along with the change of shear rate γ, viscosities il also changes.In contrast, be less than 10 at shear rate γ
1or more than 10
5time, regardless of the change of shear rate γ, viscosities il all represents roughly certain value.Therefore, 10 are kept in shear rate (injection speed)
1~ 10
5scope in certain regulation certain value time, the viscosity of molten resin can be calculated from (1) formula.Such as, the shear rate γ obtained by injection speed 10mm/sec and the size of equipment are had nothing to do, and roughly become γ=10
3~ 10
4the value of left and right, meets the design conditions of above-mentioned viscosity well.On the other hand, γ=10 are represented in the equipment of the shear rate γ obtained by injection speed 100mm/sec more than 100 tons
5neighbouring value is no longer the parameter of suitable Speed Setting.Thus, in the present invention, to keep the mode of certain certain value in the scope of 5 ~ 50mm/sec to control injection speed (pace of screw rod), calculate in the scope of condition what to meet above-mentioned viscosity well, carry out the measurement of resin viscosity.
In the injection machine of coaxial screw, according to JISK7199, described shear stress τ and shear rate γ is setting injection pressure as P(Pa), if the diameter in injection nozzle hole is r(mm), if the active length of nozzle (landlength) is L(mm), if flow is Q(mm3/sec) time, represented respectively by following formula
τ=(P × r)/(4 × L) ... (2) formula
γ=(32 × Q)/(π × r
3) ... (3) formula
At this, flow Q amasss as A(mm setting screw sections
2), if injection speed (pace of screw rod) is V(mm/sec) time, be expressed from the next,
Q=A × V ... (4) formula
, therefore when setting the diameter of screw rod as D, (4) formula is expressed from the next,
Q=(π × D
2× V)/4 ... (5) formula
, when (5) formula is updated to (3) formula, become
γ=(8 × D
2× V)/r
3(6) formula.
Therefore, as a result, the viscosities il of molten resin is obtained by following formula,
η=(r
4× P)/(32 × L × D
2× V) ... (7) formula
。That is, if injection speed is certain condition, then the value owing to controlling as the value of certain injection speed, mechanical dimension is known, as long as therefore survey injection pressure P just can calculate resin viscosity based on surveying injection pressure force value.
According to the measuring method of resin viscosity of injection machine of present embodiment using such calculating formula, confirm by test the situation that the resin viscosity measured can obtain the high-precision value roughly equal with the value of the prompting of resin material manufacturer.It should be noted that, in the injection machine of present embodiment, if meeting injection speed is certain condition, then by measuring the injection pressure force value during this, and can resin viscosity be calculated.But, to in mould during injection/filling molten resin, consider due to mould cavity shape as how and injection speed also carries out situation about changing, or when carrying out superfast injection, also consider the situation that injection speed departs from from the scope of the condition that calculates meeting described viscosity well.Therefore, when carrying out the mensuration of resin viscosity, the injection nozzle 3 of usual heating cylinder front end is under the state do not contacted with mould, and under the condition that the injection speed based on FEEDBACK CONTROL is certain, carry out (under the state of freely injecting that injection speed is certain) in the measurement pattern of the resin viscosity injected, carry out the mensuration/calculating of resin viscosity.
Next, based on Fig. 5, an example of the action when viscosity calculating molten resin also adjusts the viscosity of the molten resin calculated is described.Fig. 5 represents the situation starting automatically to run after making the resin be supplied in heating cylinder be warming up to the temperature of regulation, and step 2 ~ 10 represent the action of resin viscosity measurement pattern.Such as, after the change of resin batch etc., the (step 1) when the automatic operation being shaped as shape product starts, to be counted by material feeding counting number unit 17 from the material feeding number of injection nozzle 3 injecting molten resin and exports to control unit 4.
Next, in step 2, do not reach the material feeding number that presets that is N material feeding time, continue automatically to run, on the other hand, when reaching N material feeding, shifting to step 3, retreating by advance and retreat driver element with the injection nozzle 3 of contacting dies, being separated from mould.It should be noted that, as the described material feeding number preset, as represented in the lower right side of Fig. 3, such as, be " 1000 " material feeding, utilizes manually input and carry out setting change to the hurdle of " 1000 " of Fig. 3, can changing thus to suitable material feeding number.
Next, by resin viscosity computing unit 14, use described calculating formula, calculate the viscosity (step 4) of the molten resin injected from the injection nozzle retreated non-contiguously with mould due to retrogressing, carry out the judgement (step 5) of the viscosity of the molten resin calculated, at this, time in the scope that the viscosity of molten resin is accommodated in the resin viscosity of regulation, injection nozzle advance (step 6), return with the state of contacting dies and N reset to " 0 " (N=0), control unit 4 starts automatically to run (step 1) again.It should be noted that, can be judged by mean value several times in the mensuration of this resin viscosity.
On the other hand, in the judgement of the viscosity of the molten resin calculated in step 5, time in the scope that the viscosity of molten resin is not accommodated in the resin viscosity of regulation, temperature measurement unit 19 measures the temperature of the molten resin injected from injection nozzle 3, use this measurement result etc., thermostat unit 15 carries out the change (rise etc.) of the design temperature of heater 10, (step 7) in the scope thus viscosity of the molten resin injected from injection nozzle 3 being adjusted to the resin viscosity being accommodated in regulation.And, repeatedly carried out reach the temperature of regulation at the design temperature of heater 10 before step 7,8 action, as step 8, when the design temperature being confirmed heater 10 by control unit 4 reaches the situation of the temperature of regulation, resin viscosity computing unit 14 is utilized again to calculate the viscosity (step 4) of the molten resin penetrated from injection nozzle 3.It should be noted that, in step 7, be expressed as " making the design temperature of heater change Y DEG C ", but as shown in Figures 2 and 3, the heater 10 of present embodiment has heater 1 ~ 5(Xch along the length direction of heating cylinder 10), trickle temperature adjustment can be carried out by having multiple heater.
Next, after step 4, carry out the judgement (equal with step 5) of viscosity, time in the scope that the viscosity of molten resin is not accommodated in the resin viscosity of regulation, the temperature of repeatedly carrying out heater 10 changes (equal with step 7), whether the design temperature of heater 10 reaches the confirmation (equal with step 8) of the temperature of regulation, viscosity calculations (equal with step 4), the judgement (equal with step 5) of viscosity, this operation is carried out Z time (stated number), even if when reaching Z time, the viscosity of molten resin is not accommodated in the resin viscosity of regulation yet, injection machine stops automatically.On the other hand, when within Z time, the viscosity of molten resin is accommodated in the resin viscosity of regulation, injection nozzle advance, returns with the state of contacting dies and N resets to " 0 " (N=0), and control unit 4 starts automatic operation again.
As described above according to the present embodiment, in injection machine, rotate by making the screw rod 2 in heating cylinder 1 and retreat and carry out the measurement process of molten resin, afterwards, as injection process, by before making screw rod 2 and then from the cavity injection molten resin of injection nozzle 3 to mould being arranged on heating cylinder front end, described injection machine possesses: the material feeding number from injection nozzle 3 injecting molten resin is carried out to the material feeding counting number unit 17 counted, the rotary drive unit that screw rod 2 rotates is made when carrying out measurement process, and the advance and retreat driver element that injection nozzle 3 is retreated, wherein, by advance and retreat driver element, injection nozzle 3 is advanced and with contacting dies thus Iteratively forming goes out in the automatic operation of formed products, material feeding counting number unit 17 is utilized to count for the material feeding number from injection nozzle 3 injecting molten resin, when the material feeding number count down to reaches specified value, advance and retreat driver element makes injection nozzle 3 retreat together with heating cylinder 1, thus under the state making injection nozzle 3 and mould retreat non-contiguously, calculate the viscosity of the molten resin injected from injection nozzle 3, after the viscosity calculating this molten resin, described advance and retreat driver element makes injection nozzle 3 and contacting dies, again start the automatic operation of the shaping repeatedly forming product.And, the judgement of the viscosity of the molten resin calculated described in carrying out, time in the scope that the viscosity of molten resin is not accommodated in the resin viscosity of regulation, the viscosity with the molten resin of the characteristic that Yin Gaowenization and viscosity reduce penetrated from injection nozzle 3, by carrying out the change of the design temperature of the heater 10 be arranged on heating cylinder 1, is adjusted in the scope of the resin viscosity being accommodated in regulation by thermostat unit 15.Thus, when carrying out the automatic operation of Iteratively forming formed products, counted by the material feeding number of material feeding counting number unit 17 for the molten resin injected from injection nozzle 3, when the material feeding number count down to reaches the specified value preset, as resin viscosity measurement pattern, automatically calculate the viscosity of the molten resin penetrated from injection nozzle 3, time in the scope that the viscosity of the molten resin calculated is not accommodated in the resin viscosity of regulation, the change of the design temperature of heater 10 is carried out by thermostat unit 15, the viscosity of molten resin is adjusted to the resin viscosity being accommodated in regulation, and then and then, again start the automatic operation of the shaping repeatedly forming product, therefore resin viscosity measurement pattern is carried out in the automatic operation midway utilizing injection machine to manufacture formed products continuously, automatically can carry out the viscosimetric analysis of molten resin thus, viscosity adjustment on this basis, the person of simplifying the operation operation can be adjusted to the viscosity of resin and the raising of convenience can be realized.
