Description

本発明は、樹脂製容器の帯電量の測定、特に、樹脂製容器の内面と外面の電位差を測定する測定装置および測定方法に関するものである。 The present invention relates to measurement of a charge amount of a resin container, and more particularly to a measurement apparatus and a measurement method for measuring a potential difference between an inner surface and an outer surface of a resin container.

樹脂製容器が帯電することは従来から知られている。例えば、特許文献1のように、容器搬送装置によって搬送されている樹脂製容器を、電子線照射装置の前面側を通過させる間に、電子線照射装置の照射窓から電子線を照射して殺菌を行うと、図4に示すように、樹脂製容器2の壁体の内部には、マイナスの電荷が滞留し、樹脂製容器2の外側の表面2aと内側の表面2bにはプラスの電荷を持つイオンが付着した状態になる。特に、この図4の状態では、電子線の照射を直接受けた外面2a側の方が内面2b側よりも電位が高い状態になっており(外面2a側の電位をC1、内面2b側の電位をC2で示す)、外面2aと内面2bとの間に電位差Vが生じている。   It has been conventionally known that a resin container is charged. For example, as in Patent Document 1, a resin container transported by a container transport device is sterilized by irradiating an electron beam from an irradiation window of the electron beam irradiation device while passing the front side of the electron beam irradiation device. As shown in FIG. 4, a negative charge stays inside the wall of the resin container 2, and a positive charge stays on the outer surface 2a and the inner surface 2b of the resin container 2. It becomes in the state that the ion which has has adhered. In particular, in the state of FIG. 4, the outer surface 2a side that has been directly irradiated with the electron beam has a higher potential than the inner surface 2b side (the potential on the outer surface 2a side is C1, and the potential on the inner surface 2b side is ), A potential difference V is generated between the outer surface 2a and the inner surface 2b.

前記のように樹脂製容器の壁面の内部に電荷が滞留すると、外側の表面と、内部側の表面に滞留する電荷が異なって、内面と外面との間に電位差が発生すると、この樹脂製容器内に手や口が触れると、静電気が発生する場合がある。そこで、樹脂製容器の壁体の内外面の電位差がどのように存在しているかを測定する必要があった。   As described above, when electric charge stays inside the wall surface of the resin container, the electric charge staying on the outer surface and the inner surface is different, and when a potential difference occurs between the inner surface and the outer surface, this resin container If a hand or mouth touches the inside, static electricity may be generated. Therefore, it has been necessary to measure how the potential difference between the inner and outer surfaces of the wall of the resin container exists.

本発明は、樹脂製容器の内面と外面の電位差を測定する測定装置であって、電導性の液体が充填された樹脂製容器と、内部に電導性の液体が満たされ、その電導性の液体内に前記樹脂製容器が配置されるコンテナと、樹脂製容器内に充填されている電導性の液体に接続される第1電極と、コンテナ内に満たされている電導性の液体に接続される第2電極と、前記第1電極と第2電極とを連通する回路と、この回路に接続され、前記第1電極と第2電極との電位差を測定する電位差測定手段とを備えたものである。 The present invention relates to a measuring device for measuring the potential difference between the inner and outer surfaces of the resin vessel, the resin container conductivity of liquid filled, electrically conductive liquid is filled therein, the conductivity of the liquid the resin vessel is connected to the container to be laid, a first electrode connected to the electrically conductive liquid being filled in a resin container, the conductivity of the liquid which is filled into the container within A second electrode, a circuit that communicates the first electrode and the second electrode, and a potential difference measuring unit that is connected to the circuit and measures a potential difference between the first electrode and the second electrode. .

また、第2の発明は、前記第1の発明において、前記電位差測定手段と並列に抵抗を配置したことを特徴とするものである。 The second invention is characterized in that, in the first invention, a resistor is arranged in parallel with the potential difference measuring means.

さらに、第3の発明に係る測定方法は、樹脂製容器の内面と外面の電位差を測定する測定方法であって、樹脂製容器の内面と外面とをそれぞれ電導性の媒体に接触させた後に、内面に接触させた電導性の媒体と外面に接触させた電導性の媒体とを接続する回路を形成し、内面に接触させた電導性の媒体と外面に接触させた電導性の媒体との電位差を測定することにより樹脂製容器の内面と外面の電位差を測定することを特徴とするものである。 Furthermore, the measurement method according to the third invention is a measurement method for measuring the potential difference between the inner surface and the outer surface of the resin container, and after bringing the inner surface and the outer surface of the resin container into contact with the conductive medium, respectively. A potential difference between the conductive medium in contact with the inner surface and the conductive medium in contact with the outer surface is formed by forming a circuit that connects the conductive medium in contact with the inner surface and the conductive medium in contact with the outer surface. By measuring the potential difference between the inner and outer surfaces of the resin container.

本発明の測定装置は、液体を満たしたコンテナ内に、液体を充填した樹脂製容器を配置し、両容器内の液体にそれぞれ電極を挿入し、両電極を接続してスイッチによりオンオフ可能な電気回路を形成し、この電気回路内に測定手段を接続するという簡単な構成で、樹脂製容器の壁体の内面側と外面側との電位差を正確に測定することができるという利点がある。   The measuring device according to the present invention has an electric container that can be turned on and off by a switch by placing resin containers filled with liquid in a container filled with liquid, inserting electrodes into the liquid in both containers, and connecting both electrodes. There is an advantage that the potential difference between the inner surface side and the outer surface side of the wall of the resin container can be accurately measured with a simple configuration in which a circuit is formed and a measuring means is connected in the electric circuit.

内部に液体を満たした状態でコンテナを設置し、内部に飲料等の液体が充填された樹脂製容器を前記コンテナの液体内に配置する。樹脂製容器内に充填されている液体内に第1電極を挿入するとともに、コンテナ内の液体には第2電極を挿入し、これら第1電極と第2電極を接続する電気回路を形成して、スイッチによりオンオフできるようにしている。コの電気回路にオシロスコープを接続して回路内の電圧を測定する。このような簡単な構成により、簡単な操作で樹脂製容器の内面と外面との間の電位差を測定するという目的を実現した。   A container is installed in a state where the liquid is filled therein, and a resin container filled with a liquid such as a beverage is disposed in the liquid of the container. The first electrode is inserted into the liquid filled in the resin container, the second electrode is inserted into the liquid in the container, and an electric circuit for connecting the first electrode and the second electrode is formed. The switch can be turned on and off. Connect an oscilloscope to the electrical circuit and measure the voltage in the circuit. With such a simple configuration, the object of measuring the potential difference between the inner surface and the outer surface of the resin container with a simple operation has been realized.

以下、図面に示す実施例により本発明を説明する。何らかの操作により、その壁体に電荷が滞留し、しかもその電荷に偏りがある樹脂製容器2は、例えば、樹脂製容器2の外面2a側と内面2b側との間に電位差が生じている。この実施例に係る測定装置はその電位差を測定する装置である。   Hereinafter, the present invention will be described with reference to embodiments shown in the drawings. For example, in the resin container 2 in which charges are accumulated in the wall body due to some operation and the charge is biased, a potential difference is generated between the outer surface 2 a side and the inner surface 2 b side of the resin container 2. The measuring apparatus according to this embodiment is an apparatus for measuring the potential difference.

この測定装置は、樹脂製の土台4と、この土台4上に載せられ、内部に液体6が満たされた金属製のコンテナ8と、内部に液体10が充填され、前記コンテナ8内に満たされている液体6内に配置された樹脂製容器2と、樹脂製容器2内に充填されている液体10内に挿入されている第1電極12と、前記コンテナ8内に満たされている液体6内に挿入されている第2電極14と、これら第1電極12と第2電極14とを連通するとともに一端がアース16されている電気回路18と、この電気回路18に接続され、電気回路18内の電圧を測定する電圧測定手段としてのオシロスコープ20とを備えている。この電気回路18はスイッチ22によってオンオフされる。さらに、この電気回路18に接続されたオシロスコープ20と並列に接続された抵抗24を有している。   This measuring apparatus is made of a resin base 4, a metal container 8 placed on the base 4 and filled with a liquid 6, and filled with a liquid 10, and filled in the container 8. The resin container 2 disposed in the liquid 6, the first electrode 12 inserted in the liquid 10 filled in the resin container 2, and the liquid 6 filled in the container 8. The second electrode 14 inserted in the electric circuit 18, the electric circuit 18 communicating with the first electrode 12 and the second electrode 14 and having one end grounded 16, and the electric circuit 18 connected to the electric circuit 18 And an oscilloscope 20 as voltage measuring means for measuring the internal voltage. The electric circuit 18 is turned on / off by a switch 22. Furthermore, it has a resistor 24 connected in parallel with an oscilloscope 20 connected to the electric circuit 18.

前記測定装置のスイッチ22をオンにすると(図2に示す状態)、電気回路18が接続され、樹脂製容器2内に充填されている液体10が接している樹脂製容器2の内面2b側と、金属容器8内に満たされている液体6が接している樹脂製容器2の外面2a側との電位差(電圧)が、前記オシロスコープ20に表示される。図3は、オシロスコープ20に表示された電圧波形であり、樹脂製容器2の壁体の内面2b側と外面2a側との電位差が測定される。また、この図3に示すように、電気回路18が接続されることによって樹脂製容器2の内外面2a、2bに不均衡に滞留していた電荷が流れてほぼ等しくなり、電位差がなくなる(図2の符号0は、測定前の電位差V(図1参照)が消滅したことを示している)。   When the switch 22 of the measuring device is turned on (state shown in FIG. 2), the electric circuit 18 is connected, and the inner surface 2b side of the resin container 2 with which the liquid 10 filled in the resin container 2 is in contact. The potential difference (voltage) from the outer surface 2a side of the resin container 2 in contact with the liquid 6 filled in the metal container 8 is displayed on the oscilloscope 20. FIG. 3 is a voltage waveform displayed on the oscilloscope 20, and the potential difference between the inner surface 2b side and the outer surface 2a side of the wall of the resin container 2 is measured. Further, as shown in FIG. 3, by connecting the electric circuit 18, the charges staying in an unbalanced manner on the inner and outer surfaces 2a, 2b of the resin container 2 flow and become almost equal, and there is no potential difference (see FIG. 3). The symbol 0 of 2 indicates that the potential difference V before measurement (see FIG. 1) has disappeared).

この測定装置によって樹脂製容器2の電位差を測定する場合に、スイッチ22をオンにすると瞬間的に電位差が低下するため測定しづらいので、この実施例では抵抗24を介在させて反応速度を遅くしている。また、抵抗24を介しているので、抵抗値から電流値を求め、電流値がどのくらいの時間流れるかを計測することにより電荷の量を算出することもできる。   When measuring the potential difference of the resin container 2 with this measuring device, since the potential difference instantaneously decreases when the switch 22 is turned on, it is difficult to measure. Therefore, in this embodiment, the reaction rate is slowed by interposing a resistor 24. ing. Further, since the resistor 24 is interposed, the amount of charge can be calculated by obtaining a current value from the resistance value and measuring how long the current value flows.

なお、前記実施例では、コンテナ8を鉄やステンレス等の金属製としたが、金属製に限らず樹脂製等であってもよい。また、金属製のコンテナ8の場合には、電極(第2電極14)を内部に満たされた液体6とコンテナ8のいずれかに接続すればよいが、樹脂製のコンテナ8の場合には、電極14は内部の液体に接続しなければならない。コンテナ8内に入れる液体6および樹脂製容器2内に充填される液体10は、導電性をある程度有する液体であればどのような液体を使用してもよい。また、前記コンテナ8を載せる土台4は省略することもできる。   In the above embodiment, the container 8 is made of metal such as iron or stainless steel, but it is not limited to metal but may be made of resin. In the case of the metal container 8, the electrode (second electrode 14) may be connected to either the liquid 6 filled in the container or the container 8, but in the case of the resin container 8, The electrode 14 must be connected to the liquid inside. Any liquid may be used as the liquid 6 placed in the container 8 and the liquid 10 filled in the resin container 2 as long as the liquid has some conductivity. Further, the base 4 on which the container 8 is placed can be omitted.

前記実施例では、電気回路18の連通遮断を行うスイッチ22を、図示の位置に設けたが、例えば、図1中に符号Aで示す位置にスイッチを設けるようにしてもよい。但し、この位置にスイッチを設けた場合には、コンテナが樹脂製の場合には問題ないが、金属製のコンテナの場合には、床面に直接設置すると樹脂製容器内とコンテナが連通してしまうので、非電導性の土台を設ける必要がある。なお、この実施例では、電導性の媒体として水などの液体6、10を用いたが、このような液体以外の電導性の媒体として、例えば、銅やアルミニウムの薄膜を用いることもできる。これら薄膜を樹脂製容器2の内面と外面に貼り付けても前記実施例と同様に電位差を測定することができる。
In the above embodiment, the switch 22 that cuts off the communication of the electric circuit 18 is provided at the illustrated position. However, for example, a switch may be provided at the position indicated by the symbol A in FIG. However, if a switch is provided at this position, there is no problem when the container is made of resin. However, in the case of a metal container, the container is connected to the resin container when installed directly on the floor. Therefore, it is necessary to provide a non-conductive base. In this embodiment, the liquids 6 and 10 such as water are used as the conductive medium. However, as the conductive medium other than such a liquid, for example, a thin film of copper or aluminum can be used. Even if these thin films are affixed to the inner surface and the outer surface of the resin container 2, the potential difference can be measured in the same manner as in the previous embodiment.
