本発明は例えばガラスびん等の透光性の容器内
の酒類、飲料、調味料等の液面を測定する方法お
よび装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for measuring the liquid level of alcoholic beverages, beverages, seasonings, etc. in translucent containers such as glass bottles.
一般に、酒類、飲料、調味料等を所定のガラス
びんに充填する際充填量が基準の幅の中にあるこ
とが要求され、これは通常液面の高さで管理され
る。このため、酒類が少くとも基準面迄達してい
るか否かを各びんに充填する際に測定しなければ
ならない。 Generally, when filling a predetermined glass bottle with alcoholic beverages, beverages, seasonings, etc., it is required that the filling amount be within a standard width, and this is usually controlled by the height of the liquid level. For this reason, it is necessary to measure whether the alcoholic beverage has reached at least the reference level when filling each bottle.

という欠点があつた。 Conventionally, as an example of such a measurement method, a light source is placed on one side of the container so that the light beam is emitted horizontally to the liquid surface, and a light-receiving camera is placed horizontally to the liquid surface on the other side of the container. The light transmitted through the container and the liquid is received by a light-receiving camera, and a photoelectric converter connected to the light-receiving camera converts the light into, for example, voltage. It was designed to measure the liquid level position. However, in such conventional measurement methods, the light source is placed horizontally at the liquid level, so the boundary of transmitted light between areas with liquid and areas without liquid is not clearly visible, making it difficult to confirm the liquid level position. There was a drawback.
本発明の目的は上述のごとき従来技術の欠点を
解消した液面測定方法を提供することにある。 An object of the present invention is to provide a liquid level measuring method that eliminates the drawbacks of the prior art as described above.

ている。 In order to achieve such an object, the present invention provides a light source assembly that is arranged on one side of a translucent container so as to emit a light beam toward the liquid surface from a position obliquely below the liquid surface in the container, and the light source assembly of the container is A light receiving camera is arranged on the opposite side of the assembly, and a photoelectric converter is connected to the light receiving camera, and the light beam from the light source assembly is irradiated to a rising part of the liquid surface due to surface tension, and the light passing through the rising part is The light receiving camera receives the reflected light from the rising portion of the liquid level on the light receiving camera side, and the liquid level position is measured by a photoelectric converter.
以下、本発明を図示の実施例に基いて詳細に説

運転中に酒等が一定量充填される。 In FIG. 1, reference numeral 10 indicates a container. The container is translucent and in the illustrated embodiment consists of a glass bottle. This container contains any liquid 11.
For example, it is filled with alcohol or the like. Generally, a large number of these containers are lined up and transported by a belt conveyor (not shown), and a certain amount of alcoholic beverages, etc. are filled during this operation.

示すように表面張力による上昇部分（せり上り部
分）１８に照射するように設定されていることで
ある。 In order to measure the amount of liquid filled, that is, the liquid level position, a light source assembly 12 is placed on one side of the container, and a light receiving camera 13 is placed on the other side of the container. In the illustrated embodiment, the light source assembly 12 comprises a light source 14 and a diffuser plate 15 for diffusing the light emitted from the light source. The light source consists, for example, of a halogen lamp that emits high-power white light. What should be noted is that this light source assembly emits a light beam 16 from a position below the liquid level 17 in the container to the part of the liquid level on the receiving camera side, that is, the rising part due to surface tension (as shown in FIG. 2). ) 18.
尚、光線を液面の下方から上昇部分１８に照射
できれば上記の光源アセンブリの構成に限定され
ることはない。例えば光源１４を液面よりも上方
に位置させ反射ミラー（図示せず）で上昇部分に
光線を照射することもできる。 Note that the structure of the light source assembly is not limited to the above, as long as the light beam can be irradiated onto the rising portion 18 from below the liquid surface. For example, the light source 14 may be positioned above the liquid level and a reflecting mirror (not shown) may be used to irradiate the rising portion with a beam of light.
この上昇部分に照射された光線１６は第２図に
示すように上昇部分の円弧部１８ａで反射され、
この反射光１６ａは容器１０の壁を透過して受光

が、実用的には屈折光１６ｂは受光カメラ１３の
ピントの調整で消却する。なお、上記とは反対に
反射光をピントの調整で消却し屈折光を利用する
ようにしてもよい。 The light ray 16 irradiated to this rising part is reflected by the circular arc part 18a of the rising part, as shown in FIG.
This reflected light 16a passes through the wall of the container 10 and is received by the light receiving camera 13. In addition, the light ray 16 irradiated to the opposing rising part is refracted by the circular arc part 18b of this rising part, and this refracted light 16b is also received by the light receiving camera 13 in parallel with the reflected light 16a, but in practical terms, the refracted light 16b disappears by adjusting the focus of the light receiving camera 13. Note that, contrary to the above, the reflected light may be canceled by adjusting the focus and the refracted light may be used.
この受光カメラには光電変換器２０が接続さ

ラに一体に組込まれた形態を有している（第１図
参照）。この光電変換器は受光カメラで受け取ら
れた光を例えば電圧に変換するようになつてい
る。 A photoelectric converter 20 is connected to the light-receiving camera, and in the illustrated embodiment, the photoelectric converter is integrated into the light-receiving camera (see FIG. 1). This photoelectric converter is adapted to convert the light received by the light receiving camera into, for example, a voltage.
上昇部分１８で反射された光が光電変換器で電
圧に変換され、この変換された電圧を映像器等の
任意のデイスプレー手段で表示すると、第２図に
示すように液面１７の位置を示す明るい帯状部分
２１が得られる。従つて、この帯状部分を見て液
面即ち充填量を知ることができ、この充填量が基
準の幅にあるか否かを判別することができる。 The light reflected by the rising portion 18 is converted into voltage by a photoelectric converter, and when this converted voltage is displayed on any display means such as a video camera, the position of the liquid level 17 can be determined as shown in FIG. A bright strip 21 as shown is obtained. Therefore, it is possible to know the liquid level, that is, the filling amount, by looking at this band-shaped portion, and it is possible to determine whether or not this filling amount is within the standard width.
本発明によれば、表面張力による上昇部分即ち
せり上り部分に液面より下方位置から光線を照射

つて、液体の充填量が簡単且つ明瞭に判別するこ
とができるという実益がある。 According to the present invention, a light beam is irradiated from a position below the liquid level to the rising part due to surface tension, that is, the rising part, and the reflection of the light from the rising part is used, so that the liquid level position can be clearly displayed. Therefore, there is a practical advantage that the amount of liquid filled can be easily and clearly determined.
