Description

本発明は離型剤スプレー装置の異常判定方法に関し、特に金型温度に基づく離型剤スプレー装置の異常判定方法に関する。 The present invention relates to a method for determining an abnormality in a release agent spray device, and more particularly to a method for determining an abnormality in a release agent spray device based on the mold temperature.

特許文献１に開示のスプレー剤塗布方法では、スプレーノズルからスプレー剤を噴霧するとともに、金型のスプレー剤噴霧箇所の温度を検出する。さらに、同方法では、スプレー剤噴霧開始後から、予め設定される所定時間が経過するまでの間に、検出される金型の温度が予め設定される所定温度を下回らない場合、スプレーノズルに異常が発生したと判断する。 In the spray agent coating method disclosed in Patent Document 1, the spray agent is sprayed from the spray nozzle and the temperature of the spray agent sprayed portion of the mold is detected. Further, in the same method, if the temperature of the detected mold does not fall below the preset predetermined temperature between the start of spraying the spray agent and the elapse of the preset predetermined time, the spray nozzle is abnormal. Is determined to have occurred.

ここで、離型剤スプレー量は、離型剤スプレー剤が金型へ付着した付着量に関係し、当該付着量は、主に離型剤スプレー剤に含まれる水分等が金型によって気化する気化熱に関係する。当該気化熱は、金型温度に関係する。そのため、上記スプレー剤塗布方法では、金型温度に基づいて、スプレーノズルに異常発生の有無を判断している。 Here, the amount of the release agent spray is related to the amount of adhesion of the release agent spray agent to the mold, and the amount of the adhesion is mainly vaporized by the mold such as water contained in the release agent spray agent. It is related to the heat of vaporization. The heat of vaporization is related to the mold temperature. Therefore, in the above spray agent coating method, the presence or absence of an abnormality in the spray nozzle is determined based on the mold temperature.

本願発明者等は、以下の課題を発見した。
離型剤スプレー量と、金型温度とは、あまり相関していない場合があり、離型剤スプレー装置の異常発生を良好な精度で判定することができないことがあった。 The inventors of the present application have discovered the following problems.
The amount of mold release agent sprayed and the mold temperature may not correlate well, and it may not be possible to determine the occurrence of an abnormality in the mold release agent sprayer with good accuracy.

このような一具体例について説明する。上記したスプレー剤塗布方法を用いて、離型剤のスプレー塗布を開始してから、所定時間が経過した後、金型温度Ｔ［℃］を計測した。その結果を図４に示す。離型剤スプレー量は、３水準とした。具体的には、比較例１、２、３では、離型剤スプレー量は、多量、中量、少量とそれぞれ設定した。この鋳込みショット数に対する金型温度Ｔ［℃］を示すグラフを図４に示す。図４に示すように、離型剤スプレー量と、金型温度とは、あまり相関しなかった。よって、金型温度の変化要因は、離型剤スプレー剤の気化熱以外にあると考えられる。 A specific example of this will be described. Using the spray agent coating method described above, the mold temperature T [° C.] was measured after a predetermined time had elapsed since the spray coating of the release agent was started. The result is shown in FIG. The amount of mold release agent sprayed was set to 3 levels. Specifically, in Comparative Examples 1, 2 and 3, the release agent spray amount was set to a large amount, a medium amount, and a small amount, respectively. A graph showing the mold temperature T [° C.] with respect to the number of casting shots is shown in FIG. As shown in FIG. 4, the amount of mold release agent sprayed and the mold temperature did not correlate well. Therefore, it is considered that the cause of the change in the mold temperature is other than the heat of vaporization of the release agent spray agent.

このようなスプレー剤塗布方法では、金型温度のみを考慮して、離型剤スプレー装置の異常発生の有無を判定していることから、その異常発生の判定精度に改善の余地が有った。 In such a spray agent application method, since the presence or absence of an abnormality in the release agent spray device is determined by considering only the mold temperature, there is room for improvement in the determination accuracy of the abnormality occurrence. ..

本発明は、離型剤スプレー装置の異常発生の判定精度の改善を図るものとする。 The present invention aims to improve the accuracy of determining the occurrence of an abnormality in the release agent spray device.

本発明に係る離型剤スプレー装置の異常判定方法は、
離型剤を金型へ塗布する離型剤スプレー装置の異常判定方法であって、
前記離型剤を塗布する前の金型温度から、前記離型剤を塗布した後の金型温度を減算して、温度変化量を算出するステップと、
外気温係数と鋳込みショット数係数とに基づいて、前記算出した温度変化量を修正して、基準温度変化量を算出するステップと、
前記算出した基準温度変化量に基づいて離型剤スプレー装置に異常が生じたか否かを判定するステップと、を備える。 The method for determining an abnormality in the release agent spray device according to the present invention is as follows.
This is a method for determining an abnormality in a mold release agent spray device that applies a mold release agent to a mold.
A step of calculating the amount of temperature change by subtracting the mold temperature after applying the mold release agent from the mold temperature before applying the mold release agent.
A step of correcting the calculated temperature change amount based on the outside air temperature coefficient and the casting shot number coefficient to calculate the reference temperature change amount, and
A step of determining whether or not an abnormality has occurred in the release agent spraying device based on the calculated reference temperature change amount is provided.

このような構成によれば、外気温や鋳込みショット数等、離型剤スプレーの気化熱以外の他の金型温度の変化要因を考慮して、異常検出を行うことができる。そのため、離型剤スプレー装置の異常発生の判定精度の改善を図ることができる。 According to such a configuration, abnormality detection can be performed in consideration of factors other than the heat of vaporization of the release agent spray, such as the outside air temperature and the number of casting shots, that change the mold temperature. Therefore, it is possible to improve the accuracy of determining the occurrence of an abnormality in the release agent spray device.

本発明は、離型剤スプレー装置の異常発生の判定精度の改善を図ることができる。 INDUSTRIAL APPLICABILITY The present invention can improve the accuracy of determining the occurrence of an abnormality in the release agent spray device.

以下、本発明を適用した具体的な実施形態について、図面を参照しながら詳細に説明する。ただし、本発明が以下の実施形態に限定される訳ではない。また、説明を明確にするため、以下の記載及び図面は、適宜、簡略化されている。 Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiments. Further, in order to clarify the explanation, the following description and drawings have been simplified as appropriate.

（実施の形態１）
図１を参照して実施の形態１について説明する。図１は、実施の形態１に係る離型剤スプレー装置の異常判定方法を示すフローチャートである。 (Embodiment 1)
The first embodiment will be described with reference to FIG. FIG. 1 is a flowchart showing an abnormality determination method of the release agent spray device according to the first embodiment.

本実施の形態では、離型剤スプレー装置は、少なくとも１回の鋳造工程において、離型剤を鋳造用金型にスプレーすることができる。また、離型剤スプレー装置は、連続的に繰り返し行う複数回の鋳造工程において利用することができる。 In the present embodiment, the mold release agent spraying device can spray the mold release agent onto the casting mold in at least one casting step. In addition, the release agent spraying device can be used in a plurality of casting steps that are continuously repeated.

金型温度Ｔ１を測定する（ステップＳＴ１）。具体的には、金型温度Ｔ１は、次のステップＳＴ２において離型剤が塗布される金型の一部位の温度である。金型は、ダイカストマシン等の鋳造装置に取り付けられている。金型温度Ｔ１は、離型剤が塗布されるのに適した温度範囲にあるとよい。赤外放射温度計等の非接触式センサを用いて、金型温度Ｔ１を測定することができる。 The mold temperature T1 is measured (step ST1). Specifically, the mold temperature T1 is the temperature of one part of the mold to which the mold release agent is applied in the next step ST2. The mold is attached to a casting device such as a die casting machine. The mold temperature T1 is preferably in a temperature range suitable for applying the mold release agent. The mold temperature T1 can be measured using a non-contact sensor such as an infrared radiation thermometer.

続いて、離型剤の塗布を開始する（ステップＳＴ２）。離型剤スプレー装置を用いて、離型剤を金型にスプレーすることによって塗布する。 Subsequently, the application of the release agent is started (step ST2). A mold release agent is applied by spraying the mold release agent onto a mold using a mold release agent spraying device.

続いて、所定時間が経過して、離型剤の塗布が終了するまで待機する（ステップＳＴ３）。 Subsequently, after a predetermined time has elapsed, the process waits until the application of the release agent is completed (step ST3).

続いて、金型温度Ｔ２を測定し、金型の温度変化量ΔＴ１を算出する（ステップＳＴ４）。具体的には、まず、金型温度Ｔ１と同様の測定方法を用いて、同様の部位を測定する。さらに、金型温度Ｔ１から金型温度Ｔ２を減算し、金型の温度変化量ΔＴ１を算出する。金型の温度変化量ΔＴ１を決める要因の１つは、ステップＳＴ２において金型に塗布された離型剤が気化し、金型から奪った熱量である。 Subsequently, the mold temperature T2 is measured, and the temperature change amount ΔT1 of the mold is calculated (step ST4). Specifically, first, the same part is measured by using the same measuring method as the mold temperature T1. Further, the mold temperature T2 is subtracted from the mold temperature T1 to calculate the mold temperature change amount ΔT1. One of the factors that determines the amount of temperature change ΔT1 of the mold is the amount of heat taken from the mold by the release agent applied to the mold in step ST2.

続いて、外気温に基づいて、金型の温度変化量ΔＴ１を修正する（ステップＳＴ５）。具体的には、金金型の温度変化量ΔＴ１と外気温係数ＯＴ１とを乗算し、外気温修正温度変化量ΔＴ２を算出する。 Subsequently, the temperature change amount ΔT1 of the mold is corrected based on the outside air temperature (step ST5). Specifically, the temperature change amount ΔT1 of the mold and the outside air temperature coefficient OT1 are multiplied to calculate the outside air temperature correction temperature change amount ΔT2.

外気温係数ＯＴ１は、金型温度に対する外気温の影響に基づいて決定することができる。例えば、外気温が高くなると、金型の温度変化量ΔＴ１が増加する傾向にある場合がある。このような場合、外気温係数ＯＴ１は、外気温が高くなるにつれて、減少する傾向であってもよい。外気温修正温度変化量ΔＴ２は、外気温係数ＯＴ１に基づいて、金型の温度変化量ΔＴ１を修正した値であり、外気温を考慮して算出される。 The outside air temperature coefficient OT1 can be determined based on the influence of the outside air temperature on the mold temperature. For example, when the outside air temperature rises, the amount of temperature change ΔT1 of the mold may tend to increase. In such a case, the outside air temperature coefficient OT1 may tend to decrease as the outside air temperature rises. The outside air temperature modified temperature change amount ΔT2 is a value obtained by modifying the mold temperature change amount ΔT1 based on the outside air temperature coefficient OT1, and is calculated in consideration of the outside air temperature.

続いて、鋳込みショット数に基づいて、金型の温度変化量ΔＴ１を修正する（ステップＳＴ６）。具体的には、外気温修正温度変化量ΔＴ２と鋳込みショット数係数ＳＨ１とを乗算し、基準温度変化量ΔＴ３を算出する。 Subsequently, the temperature change amount ΔT1 of the mold is corrected based on the number of casting shots (step ST6). Specifically, the reference temperature change amount ΔT3 is calculated by multiplying the outside air temperature correction temperature change amount ΔT2 and the casting shot number coefficient SH1.

鋳込みショット数係数ＳＨ１は、金型温度に対する鋳込みショット数の影響に基づいて決定することができる。例えば、鋳込みショット数が増加すると、金型の温度変化量ΔＴ１が増加する傾向にある場合がある。このような場合、鋳込みショット数係数ＳＨ１は、鋳込みショット数が増加するにつれて、減少する傾向であってもよい。基準温度変化量ΔＴ３は、鋳込みショット数係数ＳＨ１に基づいて、外気温修正温度変化量ΔＴ２を修正した値であり、鋳込みショット数を考慮して算出される。言い換えると、基準温度変化量ΔＴ３は、外気温や鋳込みショット数の影響を抑制するように、金型の温度変化量ΔＴ１を修正した値である。 The casting shot number coefficient SH1 can be determined based on the influence of the casting shot number on the mold temperature. For example, as the number of casting shots increases, the amount of temperature change ΔT1 of the mold may tend to increase. In such a case, the casting shot number coefficient SH1 may tend to decrease as the casting shot number increases. The reference temperature change amount ΔT3 is a value obtained by modifying the outside air temperature correction temperature change amount ΔT2 based on the casting shot number coefficient SH1, and is calculated in consideration of the casting shot number. In other words, the reference temperature change amount ΔT3 is a value obtained by modifying the temperature change amount ΔT1 of the mold so as to suppress the influence of the outside air temperature and the number of casting shots.

基準温度変化量ΔＴ３が所定の温度域ＴＲ１より大きい場合（ステップＳＴ７−１：ＹＥＳ）、警報を発生させる（ステップＳＴ７−２）。基準温度変化量ΔＴ３が所定の温度域ＴＲ１より大きい場合、離型剤が金型に付着した量が多過ぎると推測される。そのため、スプレー装置に異常が発生していると判定し、警報を発生させることによって、スプレー装置の異常の発生をスプレー装置のオペレータに通知することができる。オペレータは、スプレー装置の異常の発生を確認し、異常を取り除くことができる。 When the reference temperature change amount ΔT3 is larger than the predetermined temperature range TR1 (step ST7-1: YES), an alarm is generated (step ST7-2). When the reference temperature change amount ΔT3 is larger than the predetermined temperature range TR1, it is presumed that the amount of the mold release agent adhering to the mold is too large. Therefore, it is possible to notify the operator of the spray device of the occurrence of the abnormality of the spray device by determining that an abnormality has occurred in the spray device and generating an alarm. The operator can confirm the occurrence of an abnormality in the spray device and eliminate the abnormality.

また、基準温度変化量ΔＴ３が所定の温度域ＴＲ１より小さい場合（ステップＳＴ７−１：ＮＯ、ステップＳＴ８−１：ＹＥＳ）、警報を発生させる（ステップＳＴ８−２）。基準温度変化量ΔＴ３が所定の温度域ＴＲ１より小さい場合、離型剤が金型に付着した量が少な過ぎると推測される。温度域ＴＲ１は、所定の上限値と下限値とを有する所定の温度範囲である。そのため、ステップＳＴ７−２と同様に、スプレー装置に異常が発生していると判定し、警報を発生させることで、スプレー装置の異常の発生をスプレー装置のオペレータに通知することができる。 Further, when the reference temperature change amount ΔT3 is smaller than the predetermined temperature range TR1 (step ST7-1: NO, step ST8-1: YES), an alarm is generated (step ST8-2). When the reference temperature change amount ΔT3 is smaller than the predetermined temperature range TR1, it is presumed that the amount of the mold release agent adhering to the mold is too small. The temperature range TR1 is a predetermined temperature range having a predetermined upper limit value and a predetermined lower limit value. Therefore, as in step ST7-2, it is possible to notify the operator of the spray device of the occurrence of the abnormality of the spray device by determining that an abnormality has occurred in the spray device and generating an alarm.

また、基準温度変化量ΔＴ３が所定の温度域ＴＲ１内にある場合（ステップＳＴ８−１：ＮＯ）、鋳造装置を通常運転し、鋳造工程を進める（ステップＳＴ９）。基準温度変化量ΔＴ３が所定の温度域ＴＲ１内にある場合、スプレー装置に異常が発生しておらず、離型剤スプレー装置は良好な動作をすると考えられる。鋳造装置を通常運転し、鋳造工程を進めても、型剤スプレー装置を用いて適量な離型剤を金型に塗布することができてよい。 When the reference temperature change amount ΔT3 is within the predetermined temperature range TR1 (step ST8-1: NO), the casting apparatus is normally operated and the casting process is advanced (step ST9). When the reference temperature change amount ΔT3 is within the predetermined temperature range TR1, it is considered that no abnormality has occurred in the spray device and the release agent spray device operates satisfactorily. Even if the casting apparatus is normally operated and the casting process is advanced, an appropriate amount of mold release agent may be applied to the mold using the mold agent spraying apparatus.

以上より、上記した異常判定方法によれば、外気温や鋳込みショット数等、離型剤スプレーの気化熱以外の他の金型温度変化要素を考慮して基準温度変化量ΔＴ３を算出する。基準温度変化量ΔＴ３と温度域ＴＲ１とを比較することによって、離型剤スプレー装置の異常が発生したか否かを判定することができる。そのため、離型剤スプレー装置の異常発生の判定精度の改善を図ることができる。 From the above, according to the above-mentioned abnormality determination method, the reference temperature change amount ΔT3 is calculated in consideration of other mold temperature change factors other than the heat of vaporization of the mold release agent spray, such as the outside air temperature and the number of casting shots. By comparing the reference temperature change amount ΔT3 with the temperature range TR1, it can be determined whether or not an abnormality has occurred in the release agent spray device. Therefore, it is possible to improve the accuracy of determining the occurrence of an abnormality in the release agent spray device.

（実験）
次に、離型剤スプレー装置を用いて、離型剤を金型に塗布し、塗布前後の金型温度を計測した実験１、２について説明する。 (Experiment)
Next, Experiments 1 and 2 in which the mold release agent is applied to the mold using a mold release agent spray device and the mold temperature before and after the coating is measured will be described.

実験１、２の実験条件のうち、鋳込みショット数は９水準に設定した。実験１において、参考例１、参考例２、参考例３では、離型剤スプレー量は、多量、中量、少量とそれぞれ設定した。参考例１、参考例２、参考例３では、外気温は同じ条件である。実験１において計測した金型の温度変化量ΔＴ１を鋳込みショット数毎に算出し、この算出した結果を図２に示した。 Of the experimental conditions of Experiments 1 and 2, the number of casting shots was set to 9 levels. In Experiment 1, in Reference Example 1, Reference Example 2, and Reference Example 3, the release agent spray amount was set to a large amount, a medium amount, and a small amount, respectively. In Reference Example 1, Reference Example 2, and Reference Example 3, the outside air temperature is the same condition. The amount of temperature change ΔT1 of the mold measured in Experiment 1 was calculated for each number of casting shots, and the calculated result is shown in FIG.

実験２において、参考例４、参考例５の外気温を、夏、冬とそれぞれ設定した。言い換えると、参考例４の外気温は、参考例５の外気温と比較して高い。参考例４、参考例５では、離型剤スプレー量は同量と設定した。実験２において計測した金型の温度変化量ΔＴ１を鋳込みショット数毎に算出し、この算出した結果を図３に示した。 In Experiment 2, the outside air temperatures of Reference Example 4 and Reference Example 5 were set to summer and winter, respectively. In other words, the outside air temperature of Reference Example 4 is higher than the outside air temperature of Reference Example 5. In Reference Example 4 and Reference Example 5, the amount of the release agent spray was set to be the same. The amount of temperature change ΔT1 of the mold measured in Experiment 2 was calculated for each number of casting shots, and the calculated result is shown in FIG.

図２に示すように、参考例１、参考例２、参考例３は、この順に、金型の温度変化量ΔＴ１が高かった。離型剤スプレー量が多いと、金型の温度変化量ΔＴ１が高くなる傾向にある。 As shown in FIG. 2, in Reference Example 1, Reference Example 2, and Reference Example 3, the amount of temperature change ΔT1 of the mold was higher in this order. When the amount of the mold release agent sprayed is large, the amount of temperature change ΔT1 of the mold tends to be high.

鋳込みショット数が０（ゼロ）である場合の、参考例１〜３の塗布前後の金型の温度変化量ΔＴ１は、鋳込みショット数が０より大きい場合の、参考例１〜３の塗布前後の金型の温度変化量ΔＴ１と比較して、低い。鋳込みショット数が増加すると、参考例１〜３の塗布前後の金型の温度変化量ΔＴ１は、増加する傾向にある。参考例１〜３の塗布前後の金型の温度変化量ΔＴ１は、鋳込みショット数に影響を受ける。よって、実験１の結果に基づいて、鋳込みショット数係数ＳＨ１を決定してもよい。 When the number of casting shots is 0 (zero), the amount of temperature change ΔT1 of the mold before and after coating of Reference Examples 1 to 3 is before and after coating of Reference Examples 1 to 3 when the number of casting shots is larger than 0. It is lower than the amount of temperature change ΔT1 of the mold. As the number of casting shots increases, the amount of temperature change ΔT1 of the mold before and after coating of Reference Examples 1 to 3 tends to increase. The amount of temperature change ΔT1 of the mold before and after coating in Reference Examples 1 to 3 is affected by the number of casting shots. Therefore, the casting shot number coefficient SH1 may be determined based on the result of Experiment 1.

図３に示すように、参考例４は、参考例５と比較して塗布前後の金型の温度変化量ΔＴ１が高かった。参考例４は、参考例５と比較して外気温が高い。よって、参考例４、５の塗布前後の金型の温度変化量ΔＴ１は、外気温に影響を受ける。よって、実験２の結果に基づいて、外気温係数ＯＴ１を決定してもよい。 As shown in FIG. 3, in Reference Example 4, the amount of temperature change ΔT1 of the mold before and after coating was higher than that in Reference Example 5. Reference example 4 has a higher outside air temperature than reference example 5. Therefore, the amount of temperature change ΔT1 of the mold before and after coating in Reference Examples 4 and 5 is affected by the outside air temperature. Therefore, the outside air temperature coefficient OT1 may be determined based on the result of Experiment 2.

なお、本発明は上記実施の形態に限られたものではなく、趣旨を逸脱しない範囲で適宜変更することが可能である。また、本発明は、上記実施の形態やその一例を適宜組み合わせて実施してもよい。 The present invention is not limited to the above embodiment, and can be appropriately modified without departing from the spirit. Further, the present invention may be carried out by appropriately combining the above-described embodiments and examples thereof.
