Inspecting apparatus for foreign matter
First Claim
1. An inspecting apparatus of a foreign matter for detecting the foreign matter contained in a sealed bottle, containing a liquid product, characterized by:
- a light source radiating light from over the top portion of said sealed bottle into said liquid in order to intensify the contrast of light and darkness of the liquid and the foreign matter;
a conical prism disposed closely to the bottom face of said sealed bottle in order to enlarge said foreign matter;
an imaging means disposed under said conical prism, intensifying the contrast of light and darkness of said liquid and the foreign matter and also obtaining an enlarged image of the foreign matter in said liquid by receiving the light through said conical prism from said light source and passing through said liquid; and
a detecting means detecting the foreign matter contained in said sealed bottle containing the foreign matter in the liquid deposited in the concavity of the inside bottom portion of said sealed battle by processing signals of said images including all area of the bottom face of said sealed bottle obtained by said imaging means.

Abstract
In an inspecting apparatus for a foreign matter for detecting a foreign matter got entered an object being inspected that contains a liquid product by inspecting the object being inspected optically with imaging means, a conical prism is disposed between the object being inspected and the imaging means. Consequently, it is possible to provide an inspecting apparatus for a foreign matter for use in a production line for manufacturing liquid products, such as drinks and liquid drugs, which can detect in a reliable manner whether a foreign matter has entered a liquid inside a container, such as a bottle or a PET bottle, and a foreign matter in a colored bottle or PET bottle or in a colored liquid as well.

17. A process for detecting a foreign matter in a sealed bottle containing a liquid product, characterized by:
-
radiating light from over the top portion of said sealed bottle into said liquid in order to intensify the contrast of light and darkness of the liquid and the foreign matter;
enlarging said foreign matter by a conical prism disposed closely to the bottom face of said sealed bottle in order to enlarge said foreign matter;
intensifying the contrast of light and darkness of said liquid and the foreign matter and also obtaining an enlarged image of the foreign matter in said liquid by receiving the light through said conical prism from said light source and passing through said liquid by an imaging means disposed under said conical prism; and
detecting a foreign matter contained in said sealed bottle containing foreign matters in the liquid deposited in the concavity of the inside bottom portion of said sealed bottle by processing signals of said images, by a detecting means, including all area of the bottom face of said sealed bottle obtained by said imaging means. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)
