Fig. 4 represents the pretreatment in analytical equipment.The signal of linear transducer is low pass filtering device 56 and smoothing, and is taken out radio-frequency component by high-pass filter 58, and 3 intervals during according to for example initial stage at matched moulds, mid-term, end are divided, and decomposed according to frequency content by frequency decomposition portion 62.By the signal of signal, the temperature signal of mould and 1 matched moulds of the signal acquisition of other sensor of the signal of linear transducer and the encoder of servo motor.Even if the signal decomposition of the temperature signal of mould and other sensor is frequency content, also can keep original Wave data to process.In the additional moment data of these signals, as by tactic time series data of moment, be stored in time series memory 64.So-called time series refers to the order of matched moulds time repeatedly, and time series data is the data of each mould, even if mold closing mechanism 2 is identical, if mould difference is different data.In addition, in time series memory 64, store the signal from multiple mold closing mechanisms.
In the signal of linear transducer, represent by the low-frequency component of low pass filter 56 how mould follows the action of servo motor.Use the poor of the signal of the linear transducer of matched moulds while finishing and desired value, can change the desired value of the encoder of servo motor side.The caused delay of following of distortion of the mechanism that in addition, the low-frequency component of the signal of the encoder of servo motor and the signal of linear transducer poor represents to follow the centres such as crank mechanism and the mould contacting of upper and lower mould.If the radio-frequency component by high-pass filter 58 is carried out to frequency decomposition, can observe the vibration of the caused mould of contact of upper and lower mould.This vibrometer is applied to the power of mould and the distortion of mould while being shown in matched moulds.
If utilize strain transducer to measure the stress that is applied to mould, can infer vibration and the distortion of the caused mould of stress that is applied to mould in the time of matched moulds.In addition, the signal of strain transducer is the signal of the same race with the radio-frequency component of the signal of linear transducer.The waveform of the sound wave producing can observe upper and lower mould contact by the signal of sound transducer time, this becomes the signal of the situation of the contact that represents mould.The cooling whether suitable signal that obtains mould by the signal of temperature sensor, in addition, also can calculate the degree of the thermal expansion of mould.And, the variation of these signals, for example, with the residual quantity of the mean value in past, or with the residual quantity of signal last time also can as represent mould stability signal and use.
The signal being stored in time series memory 64 comprises normal mold closing mechanism that is possesses normal mould with the signal of the mold closing mechanism of normal driving mechanism and from the signal that becomes the mold closing mechanism that checks object.In addition, the main purpose of the inspection of mold closing mechanism is to determine the mould that needs maintenance before the underproof product of generation.Given this, below, the inspection of omitting the driving mechanism of mold closing mechanism, only describes the inspection of mould.
After the manufacture of mould, there is unsettled period at initial stage (during the initial stage) during soon, if through transit to stationary phase in this period, finally arrive performance and become unsettled period (amphibolia), and needing to safeguard.In addition, the number of times that carries out matched moulds in amphibolia is more, more needs large-scale maintenance.Therefore, target is to detect in advance amphibolia as far as possible.Mould after manufacture through, mould after safeguarding through all similar, all exists and safeguards amphibolia afterwards, stationary phase afterwards and last amphibolia.Therefore, according to known which mould of the history of mould in stationary phase, using the signal of the mould from stationary phase as normal signal, in the future since manufacturing through long-standing or from safeguarding that signal through long-standing mould is as checking object.
As shown in Figure 5, will be categorized as normal signal from the signal of time series memory 64 and check object signal.By cluster analysis portion 66, generate the cluster based on normal signal, using the inspection object signal departing from from this cluster as abnormal signal, corresponding mould is safeguarded, at least as the candidate of safeguarding.
Fig. 6 schematically shows cluster analysis, signal list is shown as to three dimensional signal herein.If collection normal signal, produces cluster, depart from from cluster × signal indication is the mould that needs maintenance.Therefore,, by cluster analysis, can determine the mould that needs maintenance.Due to detecting from cluster departs from significantly, so carry out time series analysis.Even for example identical a signal, in the case of as shown in the solid line of Fig. 6 towards advancing in the border of b, c, a and cluster, need safeguard.In the case of terminate in the inner side on border of d, e, a and cluster as the dotted line of Fig. 6, do not need to safeguard immediately.Therefore,, if utilize cluster analysis portion 66 to differentiate from cluster and depart from or terminate in cluster according to the track of signal, can determine the mould departing from from stationary phase.
Fig. 7 is illustrated in the signal waveform of linear transducer while utilizing encoder to carry out FEEDBACK CONTROL to servo motor, matched moulds amortization period.Even if the position of motor-end (anglec of rotation of motor output shaft) is constant, till the interval of 80 microsecond intermodes slowly dwindles, last larger vibration has the amount in 1 cycle.The upper and lower mould of these vibration expressions contacts while is compressed, completes the process of matched moulds.And under the state of keeping intact at the waveform of Fig. 7, to be difficult to judgement be normal or need to safeguard, so whether the frequency content of resolving into is differentiated from the cluster of the signal of the mould of stationary phase and departed from, differentiate and need to safeguard.
In an embodiment, will become frequency content from the signal decomposition of linear transducer etc., analyze but also can signal waveform keep intact, or also can extract the characteristic quantities such as the amplitude of signal and analyze.Signal from linear transducer etc. is most important in the terminal stage of matched moulds, and before mould starts to contact, importance is lower.Therefore, also can after microwave (Wavelet) conversion, carry out cluster analysis to carrying out from the signal of linear transducer etc.In the analysis that will safeguard whether, use cluster analysis, but also can use the neutral net (Neural Networks) using the signal from normal mould as teaching signal.Or also can obtain the signal of differentiating normal mould and the parameter that needs the signal of the mould of safeguarding by discriminant analysis in addition, and differentiate.In addition, without obtaining signal according to each matched moulds, also can be for example with 1 time on the 1st, or 1 hour 1 inferior frequency obtains signal.And then mold closing mechanism is not limited to servo-drive, it can be also oil pressure actuated etc.In the case of the signal from other mould that there is no other mould of the same race, do not use as normal signal, the signal of the stationary phase after can be during the initial stage after manufacturing of the mould from identical uses as normal signal.In addition, also can append linear transducer 24 is set ball screw, the elbow-bar mechanism etc. of the driving mechanism of mould.
