Abstract
Abstract A method of inspecting bottles comprises directing diffused light rays on bottles to be inspected and scanning the bottles thus irradiated. The bottles, in each of which an optical system with a light receiving unit is inserted, are rotated for scanning. A device for inspecting bottles is provided with a rotary turret, on which a plurality of bottle supports are rotatably and vertically movably arranged at regular angular intervals, irradiating units, optical systems with light receiving units arranged so as to enter into the bottles, and transducers for converting light signals received by the optical systems into electrical signals. The use of diffused light rays makes it possible to eliminate the lens action of the bottle wall and to detect solely foreign particles or substances attached on the bottle walls.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
85 words
A method of inspecting bottles for adherent foreign matter, comprising the steps of directing diffused light rays, from an external light source, laterally through bottles to be inspected; rotating the bottles relative to the light source; diffusely reflecting light rays which have passed through the bottles at locations on the opposite sides of the bottles from the light source; directing the diffused reflected light rays on the bottles; and optically scanning, interiorly of the bottles, the reflected diffused light within the bottles during such rotation.
Claim 2
Independent Claim
85 words
A method of inspecting bottles for adherent foreign matter, comprising the steps of directing diffused light rays, from an external light source, laterally through bottles to be inspected; rotating the bottles relative to the light source; diffusely reflecting light rays which have passed through the bottles at locations on the opposite sides of the bottles from the light source; directing the diffused reflected light rays on the bottles; and optically scanning, interiorly of the bottles, the reflected diffused light within the bottles during such rotation.
Claim 3
Independent Claim
156 words
A method oF inspecting bottles for adherent foreign matter, comprising the steps of moving the bottles in spaced relation along a path of travel while rotating and axially reciprocating the bottles; during travel of the bottles along the path, directing diffused light rays, from an external source of light, laterally through the bottles to be inspected; simultaneously optically scanning, interiorly of the bottles, the diffused light within the bottles during such rotation and axial reciprocation to provide optical output signals corresponding to the scanned diffused light within the bottles; converting the optical output signals into electrical signals; responsive to the electrical signals, separating bottles having adherent foreign matter from bottles free of adherent foreign matter; diffusely reflecting light rays which have passed through the bottles from locations on the sides of the bottles opposite the light source; directing the reflected diffused light rays on the bottles; and optically scanning the reflected diffused light within the bottles.
Claim 4
Independent Claim
156 words
A method oF inspecting bottles for adherent foreign matter, comprising the steps of moving the bottles in spaced relation along a path of travel while rotating and axially reciprocating the bottles; during travel of the bottles along the path, directing diffused light rays, from an external source of light, laterally through the bottles to be inspected; simultaneously optically scanning, interiorly of the bottles, the diffused light within the bottles during such rotation and axial reciprocation to provide optical output signals corresponding to the scanned diffused light within the bottles; converting the optical output signals into electrical signals; responsive to the electrical signals, separating bottles having adherent foreign matter from bottles free of adherent foreign matter; diffusely reflecting light rays which have passed through the bottles from locations on the sides of the bottles opposite the light source; directing the reflected diffused light rays on the bottles; and optically scanning the reflected diffused light within the bottles.
Claim 5
Dependent Claim
115 words
Apparatus for inspecting bottles for adherent foreign matter, comprising, in combination, at least one external light source; means operable to direct diffused light rays from said source laterally through the bottles to be inspected; at least one optical system insertable into the bottles to optically scan, interiorly of the bottles, the diffused light within the bottles; driving mechanism operable to effect relative rotation of said bottles and said optical system during such optical scanning; and reflecting means positioned on the sides of said bottles opposite said light source and operable to diffusely reflect light rays, which have passed through the bottles, on the bottles; said optical system scanning the reflected diffused light within the bottles.
