異物、透明容器表面の傷及び汚れを識別して、異物を検
出する透明容器の異物検査装置に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foreign material inspection device for a transparent container, and more particularly, a transparent container for detecting foreign material by identifying foreign material in liquid, scratches and stains on the surface of the transparent container. Foreign matter inspection device.

The ampoule container is washed with ultrapure water.

る。The drug solution is filtered by a Millipore filter of 0.45 μm or less and injected into an ampoule in a foreign matter-free state. However, even in the strict manufacturing process as described above, in the ampoule sealing process and the like, in addition to foreign substances corresponding to fine glass fragments, foreign substances of unknown cause may be mixed. Therefore, for the ampoule of the product, up to 50 foreign substances within 10 μm and up to 5 foreign substances within 25 μm are permitted according to the pharmaceutical standard. For the time being, this pharmaceutical standard will be the development target of the foreign substance inspection device, but in view of the large regulation of the future standard, the demand for higher performance foreign substance inspection device is increasing.

は、アンプルの高速回転後の異物の回転軌跡を画像処理
で抽出して自動検査している。In the conventional ampoule container foreign matter inspection device, the point of the inspection is to distinguish the scratch or dirt on the surface of the ampoule container from the foreign matter in the ampoule, and when the ampoule is rotated at a high speed and suddenly stopped, the inside of the ampoule container is stopped. Then, the fluctuation of scattered light of the rotating foreign matter due to the inertial force is detected by the photoelectric tube, or the rotation locus of the foreign matter after the high speed rotation of the ampoule is extracted by image processing and automatically inspected.

た、この装置では、アンプル容器の大きさに対応して、
一定面積ごとに区切った受光素子が設置されており、こ
れらの受光素子としては、光電管やフォトダイオードが
用いられており、極めて高速な検査が実施されている。In another conventional example, after rotating the ampoule at a high speed as described above, the brake is applied to stop suddenly, the transmitted light is irradiated from the side surface, and the foreign matter floating in rotation with the internal solution is transmitted light. A device has been developed that detects the change in shadow that occurs to block the shadow and sorts out whether it is good or bad. in this way,
The foreign matter changes its light quantity because it is floatingly rotated by the inertial force, but the light quantity does not change because the surface scratches and stains are stationary, which makes it possible to identify the foreign matter. Also, in this device, according to the size of the ampoule container,
Light receiving elements divided into fixed areas are installed, and photocells and photodiodes are used as these light receiving elements, and extremely high-speed inspection is performed.
しかし、前記従来装置が開発されているのにもかかわら

で実施されている。この原因は前記従来装置では、検出

人体に注射する最終製剤には、適用できない為である。
また、アンプルを高速回転させて、急停止させた状態
で、アンプル内の異物の慣性回転が起きないような高粘
度の薬液に対しては適用できない為である。However, in spite of the development of the conventional device, the foreign substance inspection in the ampoule is almost performed by visual inspection by hand. The reason for this is that the above-mentioned conventional device cannot be applied to the final preparation which is directly injected into the human body because the size of the detectable foreign substance is too large (70 μm or more).
Further, this is because it cannot be applied to a high-viscosity chemical solution in which foreign matter in the ampoule does not rotate inertially while the ampoule is rotated at a high speed and stopped suddenly.
しかしながら、前記アンプル高速回転による異物の慣性

ようとして、アンプルを高回転させるとアンプルが破損
する。実用上の回転速度は、3000〜5000rpmが限度であ
るが、この程度の回転速度では、100CST以上の高粘度液
体中の異物が十分慣性回転せず、この為、アンプル中の
浮遊異物も十分も回転せず、透過光を遮るために起こる
影の変化も発生しにくいので、光量の変化が発生しな
い。従って、ビン表面の傷や汚れと異物が識別できず
良、不良の選別ができなかった。However, the method of inertial rotation of foreign matter by high-speed rotation of ampoule is applicable to low viscosity contents of 10 CST or less where inertial rotation of foreign matter is induced by high-speed rotation of ampoule, but foreign matter in a high-viscosity solution Rotates the ampoule at high speed, brakes it and stops suddenly,
Even when the transmitted light is irradiated from the side surface of the ampoule, the inner solution is not inertially rotated. Therefore, the floating foreign matter does not rotate, and the shadow of the foreign matter does not change due to blocking the transmitted light. Therefore, the light quantity does not change, and there is a drawback that good or defective cannot be selected. Further, when the ampule is rotated at a high speed in order to give inertial rotation to the foreign matter in the high-viscosity inner solution, the ampoule is damaged. The practical rotation speed is limited to 3000 to 5000 rpm, but at this rotation speed, the foreign matter in the high viscosity liquid of 100 CST or more does not rotate sufficiently due to inertia, and therefore the floating foreign matter in the ampoule is also sufficient. Since it does not rotate and the change in the shadow caused by blocking the transmitted light does not easily occur, the light amount does not change. Therefore, scratches and stains on the bottle surface and foreign matter could not be discriminated from each other, and it was not possible to select good or bad.

The purpose is to provide a device.

異物と沈降異物の有無を正確に検査することができる。According to the present invention, since only the inside of the container is selectively irradiated with a parallel light flux having a diameter smaller than the inner diameter of the container, scratches and dirt on the side wall surface of the container are not detected, and floating in the content liquid filled in the container is prevented. Only foreign substances can be selectively detected. In addition, by irradiating the inner bottom surface of the container through the side wall of the container at an angle larger than the total reflection angle of the bottom surface of the container, scratches and dirt on the outer bottom surface are not detected, and only the sedimented foreign matter on the inner bottom surface is selectively detected. it can. Therefore, by combining the above two types of detection, it is possible to accurately inspect the presence or absence of floating foreign matter and sedimenting foreign matter in the container.

る。First, regarding the floating foreign matter inspection inside the ampoule container 10,
The light from the 150 W halogen lamp 20 is sent to the glass fiber 22 having a fiber system of 5 mm. This light is glass fiber 22
A collimating lens 18 attached to the tip of the beam forms a parallel beam with a beam system of 10 mm and a maximum illuminance of 300,000 lux and a divergence angle of 5 ° or less. From the bottom surface of the ampoule container 10 using the parallel light emitted from the collimator lens 18, the ampoule container
Irradiate the inner wall surface of 10 so that the light flux does not hit it. Then, the floating foreign matter inside the ampoule container 10 is reflected by the parallel light emitted from the collimator lens 18, and reflected by the imaging camera 32 having the low depth-of-field lens 30 provided on the side surface of the ampoule container 10. Point image is incident, foreign matter detector
It can be visualized and detected by the 36. Also,
The image due to the scratches and stains on the surface of the ampoule container 10 is negligibly smaller than the image formed by the reflected bright spot image of the foreign matter. Therefore, by this action, the floating foreign matter in the ampoule container 10 can be detected even in the highly viscous inner solution.

Insert the tungsten lamp 28 and lens 24 from the opposite direction with the ampoule container 10 in between and place 48 against the bottom surface of the ampoule container 10.
The total reflection angle should be at least °. When the light from the tungsten lamp 28 is applied to the bottom surface of the ampoule container 10 with such a weak illuminance that halation does not occur in the imaging system, the imaging camera 26 equipped with the lens 24 causes dust and dirt to adhere to the outer bottom surface of the ampoule container 10. The image is not incident, but only the reflected bright spot image of the sedimented foreign matter on the inner bottom surface of the ampoule container 10 is incident and can be detected by being visualized by the foreign matter detector 36. Due to the above action, according to this device, the molecular weight

きる。Similarly to the floating foreign matter detection method, the sedimentation foreign matter detection method uses the collimated beam from the bottom of the ampoule container 10 to generate scattered light of the sedimentation foreign matter on the bottom surface of the ampoule container 10, and captures the scattered light from the oblique direction of the ampoule container 10. There is a detection method. However, according to this method, in addition to the scattered light of the sedimented foreign matter on the inner bottom surface of the ampoule container 10, the imaging camera has an ampoule container.
10 Scattered light from dust and dirt adhering to the outer bottom may also be captured together. Further, although the ampoule is used in this embodiment, this device can be applied to any bottle.
