吐出検出装置160について説明する。吐出検出装置160は、3組のセンサ161、162、163と、当該センサ161、162、163を載置するプレート164と、プレート164を移動させるカムプレート165と、吐出検出装置制御部166とを備える。
The discharge detection device 160 will be described. The discharge detection device 160 includes three sets of sensors 161, 162, 163, a plate 164 on which the sensors 161, 162, and 163 are placed, a cam plate 165 for moving the plate 164, and a discharge detection device control unit 166. Be prepared.
センサ161、162、163について説明する。本実施形態の吐出検出装置160のセンサ161、162、163は、容器500の吐出口526から液状体が吐出する方向(吐出方向)に対して、交差する方向に複数並んで設けられている。
The sensors 161, 162, and 163 will be described. A plurality of sensors 161, 162, and 163 of the discharge detection device 160 of the present embodiment are provided side by side in a direction intersecting the direction (discharge direction) in which the liquid material is discharged from the discharge port 526 of the container 500.
ここでは、センサ161について説明する。センサ161は、発光部1611と、受光部1612を備える。発光部1611は、発光素子を備える。発光素子としては、例えば、発光ダイオードである。発光部1611は、発光素子が発光した光を受光部1612に向けて出射する。受光部1612は、受光素子を備える。受光素子としては、例えば、フォトダイオードである。受光部1612は、発光部1611から出射した光を受光素子で受光する。なお、発光部1611と受光部1612との間の光が伝搬する領域が、センサ161のセンサ検知範囲である。
Here, the sensor 161 will be described. The sensor 161 includes a light emitting unit 1611 and a light receiving unit 1612. The light emitting unit 1611 includes a light emitting element. The light emitting element is, for example, a light emitting diode. The light emitting unit 1611 emits the light emitted by the light emitting element toward the light receiving unit 1612. The light receiving unit 1612 includes a light receiving element. The light receiving element is, for example, a photodiode. The light receiving unit 1612 receives the light emitted from the light emitting unit 1611 by the light receiving element. The region where the light propagates between the light emitting unit 1611 and the light receiving unit 1612 is the sensor detection range of the sensor 161.
発光部1611が出射する光は、液状体により吸収又は反射される波長の光である。したがって、発光部1611と受光部1612の間のセンサ検知範囲に、液状体がある場合には、発光部1611を出射した光は、液状体によって遮られることから受光部1612での受光量が減少する。このように、光の減少の有無によって、センサ検知範囲に液状体が吐出されたかどうかを検出することができる。
The light emitted by the light emitting unit 1611 is light having a wavelength that is absorbed or reflected by the liquid material. Therefore, when there is a liquid material in the sensor detection range between the light emitting unit 1611 and the light receiving unit 1612, the light emitted from the light emitting unit 1611 is blocked by the liquid material, so that the amount of light received by the light receiving unit 1612 decreases. To do. In this way, it is possible to detect whether or not the liquid material is discharged into the sensor detection range depending on whether or not the light is reduced.
なお、センサ162、163は、センサ161と同じセンサである。すなわち、センサ162、163は、それぞれ発光部1621、1631、受光部1622、1632を備える。センサ162、163の動作はセンサ161と同様である。
Note that the sensors 162 and 163 are the same sensors as the sensor 161. That is, the sensors 162 and 163 include light emitting units 1621 and 1631 and light receiving units 1622 and 1632, respectively. The operations of the sensors 162 and 163 are the same as those of the sensor 161.
次に、センサ161、162、163を載置するプレート164について説明する。プレート164は、発光部載置部1641、受光部載置部1642、開口部1643、を備える。発光部載置部1641には、センサ161、162、163の発光部1611、1621、1631が配置されている。受光部載置部1642には、センサ161、162、163の受光部1612、1622、1632が配置されている。発光部載置部1641と受光部載置部1642は、開口部1643をはさんで配置されている。このようにして、プレート164の開口部1643の上部が、センサ161、162,163それぞれのセンサ検知範囲となる。容器500の吐出口526から吐出された液状体は、開口部1643を通過して、抽出口106から吐出する。
Next, the plate 164 on which the sensors 161, 162, and 163 are placed will be described. The plate 164 includes a light emitting portion mounting portion 1641, a light receiving portion mounting portion 1642, and an opening portion 1643. The light emitting units 1611, 1621, 1631 of the sensors 161, 162, and 163 are arranged on the light emitting unit mounting unit 1641. The light receiving portions 1612, 1622, 1632 of the sensors 161, 162, and 163 are arranged on the light receiving portion mounting portion 1642. The light emitting portion mounting portion 1641 and the light receiving portion mounting portion 1642 are arranged so as to sandwich the opening 1643. In this way, the upper part of the opening 1643 of the plate 164 becomes the sensor detection range of each of the sensors 161 and 162, 163. The liquid material discharged from the discharge port 526 of the container 500 passes through the opening 1643 and is discharged from the extraction port 106.
なお、本実施形態では、発光部載置部1641と受光部載置部1642のように、センサの発光部と受光部で、プレート164に載置する場所を変えているが、センサのセンサ検知領域が開口部1643の上部になるようにセンサが載置されていれば、受光部と発光部の配置を変更してもよい。例えば、開口部1643の一方側に、順にセンサの発光部、受光部、発光部を配置して、他方側に順にセンサの対応する受光部、発光部、受光部を配置してもよい。
In the present embodiment, the place where the sensor is mounted on the plate 164 is changed between the light emitting portion and the light receiving portion of the sensor, such as the light emitting portion mounting portion 1641 and the light receiving portion mounting portion 1642, but the sensor detection of the sensor If the sensor is placed so that the region is above the opening 1643, the arrangement of the light receiving portion and the light emitting portion may be changed. For example, the light emitting part, the light receiving part, and the light emitting part of the sensor may be arranged in order on one side of the opening 1643, and the corresponding light receiving part, the light emitting part, and the light receiving part of the sensor may be arranged in order on the other side.
次に、プレート164を移動させるカムプレート165について説明する。
Next, the cam plate 165 that moves the plate 164 will be described.
カムプレート165は、斜め方向に形成された傾斜溝1651と横方向に形成された横溝1652を備える。傾斜溝1651には、吐出機構130の摺動部材134から突出した突起1342が嵌入されている。横溝1652には、吐出機構130の固定部材135から突出した突起1351が嵌入されている。また、カムプレート165の上部は、吐出機構130の固定部材135から突出した抑え部材1352により、上方向に移動しないように保持されている。
The cam plate 165 includes an inclined groove 1651 formed in an oblique direction and a lateral groove 1652 formed in a lateral direction. A protrusion 1342 protruding from the sliding member 134 of the discharge mechanism 130 is fitted in the inclined groove 1651. A protrusion 1351 protruding from the fixing member 135 of the discharge mechanism 130 is fitted in the lateral groove 1652. Further, the upper portion of the cam plate 165 is held by a holding member 1352 protruding from the fixing member 135 of the discharge mechanism 130 so as not to move upward.
液状体吐出装置100が液状体を吐出するときに、吐出機構130の摺動部材134が上方向に摺動する。摺動部材134が上方向に摺動すると、摺動部材134の突起1342が上方向に移動する。突起1342は、カムプレート165の傾斜溝1651に嵌入されていることから、突起1342が上に移動すると、カムプレート165の傾斜溝1651に沿って移動する。カムプレート165は、横溝1652に嵌入された固定部材135の突起1351と抑え部材1352によって、上下方向の動作は制限されている。したがって、突起1342が上に移動すると、カムプレート165の傾斜溝1651に沿って移動することによって、カムプレート165は横方向、すなわち、液状体の吐出方向と交差する方向、に移動する。そして、プレート164は、横方向、すなわち、液状体の吐出方向と交差する方向、に移動する。これにより、プレート164に設けられているセンサ161、162、163が横方向、すなわち、容器500の吐出口526から液状体が吐出する方向(吐出方向)に対して、交差する方向であって、センサ161、162、163が並ぶ方向と同じ方向に移動する。
When the liquid material discharge device 100 discharges the liquid material, the sliding member 134 of the discharge mechanism 130 slides upward. When the sliding member 134 slides upward, the protrusion 1342 of the sliding member 134 moves upward. Since the protrusion 1342 is fitted in the inclined groove 1651 of the cam plate 165, when the protrusion 1342 moves upward, it moves along the inclined groove 1651 of the cam plate 165. The movement of the cam plate 165 in the vertical direction is restricted by the protrusion 1351 of the fixing member 135 and the holding member 1352 fitted in the lateral groove 1652. Therefore, when the protrusion 1342 moves upward, the cam plate 165 moves in the lateral direction, that is, in the direction intersecting the discharge direction of the liquid material, by moving along the inclined groove 1651 of the cam plate 165. Then, the plate 164 moves in the lateral direction, that is, in the direction intersecting the discharge direction of the liquid material. As a result, the sensors 161, 162, and 163 provided on the plate 164 intersect the lateral direction, that is, the direction in which the liquid material is discharged from the discharge port 526 of the container 500 (discharge direction). The sensors 161, 162, and 163 move in the same direction as they are lined up.
なお、カムプレート165及び吐出機構130が検出部移動部の一例である。また、吐出検出装置160が、液状体検出装置の一例である。
The cam plate 165 and the discharge mechanism 130 are examples of the detection unit moving unit. Further, the discharge detection device 160 is an example of a liquid matter detection device.
このようにして、本実施形態の吐出検出装置160は、容器500から液状体を吐出する吐出機構130、詳細には、容器500のプッシュボタン522を押圧して液状体を吐出させる摺動部材134と、プレート164とは連動している。
In this way, the discharge detection device 160 of the present embodiment is a discharge mechanism 130 that discharges the liquid material from the container 500, specifically, a sliding member 134 that presses the push button 522 of the container 500 to discharge the liquid material. And the plate 164 are interlocked with each other.
次に、吐出検出装置制御部166について説明する。吐出検出装置制御部166は、吐出検出装置160の制御を行う。吐出検出装置制御部166は、全体制御部1661、発光制御部1662、データ取得部1663、データ処理部1664、記憶部1665を備える。
Next, the discharge detection device control unit 166 will be described. The discharge detection device control unit 166 controls the discharge detection device 160. The discharge detection device control unit 166 includes an overall control unit 1661, a light emission control unit 1662, a data acquisition unit 1663, a data processing unit 1664, and a storage unit 1665.

≪液状体の汚れによる影響≫
ここで、センサ161、162、163について、発光部1611、1621、1631や受光部1612、1622、1632に、容器500の吐出口526から吐出した液状体が付着した場合の影響について説明する。なお、発光部1611、1621、1631及び受光部1612、1622、1632の汚れとしては、液状体以外にも、例えば、手の汚れや空気中のほこり等の付着による汚れがあるが、以下においては、液状体の汚れについて説明する。 <Discharge detection process ofliquid discharge device 100>
≪Effects of liquid stains≫
Here, with respect to the sensors 161, 162, and 163, the influence of the liquid material discharged from the discharge port 526 of the container 500 attached to the light emitting units 1611, 1621, 1631 and the light receiving units 1612, 1622, 1632 will be described. The stains on the light emitting parts 1611, 1621, 1631 and the light receiving parts 1612, 1622, 1632 include, for example, dirt on the hands and dirt due to adhesion of dust in the air, in addition to the liquid material. , The dirt of the liquid material will be described.
≪液状体の汚れによる影響≫
ここで、センサ161、162、163について、発光部1611、1621、1631や受光部1612、1622、1632に、容器500の吐出口526から吐出した液状体が付着した場合の影響について説明する。なお、発光部1611、1621、1631及び受光部1612、1622、1632の汚れとしては、液状体以外にも、例えば、手の汚れや空気中のほこり等の付着による汚れがあるが、以下においては、液状体の汚れについて説明する。 <Discharge detection process of
≪Effects of liquid stains≫
Here, with respect to the
図11は、センサ161、162、163の発光部1611、1621、1631や受光部1612、1622、1632に液状体の付着がない場合、すなわち、液状体の汚れがないときのデータ取得部1663で取得した検出信号のデータである。
FIG. 11 shows the data acquisition unit 1663 when there is no liquid matter attached to the light emitting parts 1611, 1621, 1631 and the light receiving parts 1612, 1622, 1632 of the sensors 161, 162, 163, that is, when the liquid material is not contaminated. It is the data of the acquired detection signal.
センサ161、162、163に液状体が付着していない場合は、容器500の吐出口526から液状体の吐出がないときのデータ取得部1663で取得したデータ(ベースライン)が、しきい値に対して十分小さい値になっている。したがって、当該しきい値でしきい値処理を行えば、容器500の吐出口526から吐出した液状体の有無を検出することが可能である。
When no liquid material adheres to the sensors 161, 162, and 163, the data (baseline) acquired by the data acquisition unit 1663 when no liquid material is discharged from the discharge port 526 of the container 500 becomes the threshold value. On the other hand, the value is sufficiently small. Therefore, if the threshold value processing is performed at the threshold value, it is possible to detect the presence or absence of the liquid material discharged from the discharge port 526 of the container 500.
図12は、センサ161、162、163の発光部1611、1621、1631や受光部1612、1622、1632に液状体の付着がある場合、すなわち、液状体の汚れがあるときのデータ取得部1663で取得したデータである。
FIG. 12 shows the data acquisition unit 1663 when the light emitting units 1611, 1621, 1631 and the light receiving units 1612, 1622, 1632 of the sensors 161, 162, 163 have liquid material attached, that is, when the liquid material is dirty. This is the acquired data.
センサ161、162、163に液状体が付着している場合は、容器500の吐出口526から液状体の吐出がないときのデータ取得部1663で取得したデータ(ベースライン)が、しきい値より大きい値になっている。したがって、センサ161、162、163に液状体の汚れが付着していない場合のしきい値を用いてしきい値処理を行うと、容器500の吐出口526から液状体の吐出がない場合でも、容器500の吐出口526から液状体の吐出したと誤検出してしまう。
When the liquid material is attached to the sensors 161, 162, and 163, the data (baseline) acquired by the data acquisition unit 1663 when the liquid material is not discharged from the discharge port 526 of the container 500 is from the threshold value. It is a large value. Therefore, if the threshold value processing is performed using the threshold value when the liquid material is not attached to the sensors 161, 162, and 163, even if the liquid material is not discharged from the discharge port 526 of the container 500, the liquid material is not discharged. It is erroneously detected that the liquid material is discharged from the discharge port 526 of the container 500.
本実施形態の吐出検出装置160において、センサ161、162、163に液状体が付着している場合でも、正常に検出することができるように処理を行う。吐出検出装置160の処理について説明する。
In the discharge detection device 160 of the present embodiment, even if liquid matter adheres to the sensors 161, 162, and 163, processing is performed so that it can be detected normally. The processing of the discharge detection device 160 will be described.

The overall control unit 1661 instructs the light emission control unit 1662 to make the light emitting units 1611, 1621, 1631 emit light. The light emission control unit 1662 causes the light emitting units 1611, 1621, and 1631 to emit light. The light emitting units 1611, 1621, 1631 emit light and emit light toward the light receiving units 1612, 1622, 1632. The light receiving units 1612, 1622, 1632 receive the light emitted by the corresponding light emitting units 1611, 1621, 1631, and output the received detection signal to the data acquisition unit 1663.

The liquid
データ処理部1664は、ステップS110で検出した結果から、液状体の吐出がない場合の検出信号の強度であるベースラインを演算する。ステップS110では、液状体の吐出がないことから、ステップS110での検出結果が、ベースラインとなる。
The data processing unit 1664 calculates the baseline, which is the strength of the detection signal when there is no discharge of the liquid material, from the result detected in step S110. Since no liquid material is discharged in step S110, the detection result in step S110 becomes the baseline.
そして、ベースラインの検出信号をしきい値処理できるようにしきい値を設定する。例えば、ベースラインに対して、一定強度をオフセットした値をしきい値とする。
Then, set the threshold value so that the baseline detection signal can be processed as a threshold value. For example, the threshold value is a value offset by a certain intensity with respect to the baseline.

The control device 140 of the liquid material discharge device 100 controls the discharge control unit 144 to operate the discharge mechanism 130 to discharge the liquid material from the discharge port 526 of the container 500.
全体制御部1661は、液状体の吐出のタイミングにあわせて、発光制御部1662に発光部1611、1621、1631を発光させるように指示する。発光制御部1662は、発光部1611、1621、1631を発光させる。発光部1611、1621、1631は、発光して光を受光部1612、1622、1632に向けて出射する。受光部1612、1622、1632は、対応する発光部1611、1621、1631が発光した光を受光して、受光した検出信号をデータ取得部1663に出力する。
The overall control unit 1661 instructs the light emission control unit 1662 to make the light emitting units 1611, 1621, 1631 emit light in accordance with the timing of discharging the liquid material. The light emission control unit 1662 causes the light emitting units 1611, 1621, and 1631 to emit light.
