Abstract
Abstract The invention relates to an apparatus for checking containers, e.g. bottles or pots by means of a transport apparatus for transporting the containers along a predetermined path and a lighting apparatus positioned at a side of said path, e.g. at least one flash light means, and a sensing apparatus, e.g. at least one video camera positioned on a corresponding position, said transport apparatus being provided, in the area of said lighting apparatus and said sensing apparatus a part, in which the containers are hung by their collars. The invention proposes to adapt an apparatus of the type mentioned in the preamble in such a way that in said part of said transport apparatus the path is rectilinear, thus avoiding the need of using means to counteract the oblique position necessary in prior art apparatus, in which the path is curved, and avoiding mechanical load due to centrifugal forces.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
155 words
Apparatus for inspecting containers for defects, each container being of the type having a bottom and a neck presenting an open mouth and each defining an axis passing through its bottom and through its open mouth, which comprises the combination of transport means for traveling the containers along a predetermined path having a rectilinear portion, said transport means including, in said rectilinear portion of the path, means for suspending the containers from the necks thereof so that their axes travel along a line of the rectilinear path portion, sensing means for viewing along a vertical optical axis penetrating said rectilinear portion of the path and for generating a rejection signal in response to detection of each defective container, illuminating means for momentarily illuminating each container in coordinated relation to the passage of its axis relative to the position of said optical axis, and ejection means responsive to the rejection signals for ejecting the defective containers.
Claim 2
Dependent Claim
155 words
Apparatus for inspecting containers for defects, each container being of the type having a bottom and a neck presenting an open mouth and each defining an axis passing through its bottom and through its open mouth, which comprises the combination of transport means for traveling the containers along a predetermined path having a rectilinear portion, said transport means including, in said rectilinear portion of the path, means for suspending the containers from the necks thereof so that their axes travel along a line of the rectilinear path portion, sensing means for viewing along a vertical optical axis penetrating said rectilinear portion of the path and for generating a rejection signal in response to detection of each defective container, illuminating means for momentarily illuminating each container in coordinated relation to the passage of its axis relative to the position of said optical axis, and ejection means responsive to the rejection signals for ejecting the defective containers.
Claim 3
Dependent Claim
23 words
Apparatus as defined in claim 1 wherein said optical axis is in line with the path traveled by the axes of said containers.
Claim 4
Dependent Claim
29 words
Apparatus as defined in claim 2 wherein said illuminating means comprises mechanism overlying said rectilinear path portion for momentarily illuminating the mouth of each container as it passes thereunder.
Claim 5
Dependent Claim
36 words
Apparatus as defined in claim 2 wherein one of said illuminating means and said sensing means is located below said bottoms of the containers and the other is located above the open tops of the containers.
Claim 6
Dependent Claim
29 words
Apparatus as defined in claim 1 wherein said illuminating means comprises mechanism overlying said rectilinear path portion for momentarily illuminating the mouth of each container as it passes thereunder.
Claim 7
Dependent Claim
52 words
Apparatus as defined in claim 5 including second sensing means and second illuminating means operating in coordinated relation along said rectilinear portion of the path for viewing through the bottoms of the containers and for generating a rejection signal in response to detection of each defective container by the second sensing means.
Claim 8
Dependent Claim
36 words
Apparatus as defined in claim 1 wherein one of said illuminating means and said sensing means is located below said bottoms of the containers and the other is located above the open tops of the containers.
Claim 9
Dependent Claim
158 words
Apparatus for inspecting containers for defects, each container being of the type having a bottom and a neck presenting an open mouth and each defining an axis passing through its bottom and centrally through its open mouth, which comprises the combination of transport means for traveling the containers along a predetermined path having a rectilinear portion, said transport means including, in said rectilinear portion of the path, means for suspending the containers from the necks thereof so that their axes travel along a line of the rectilinear path portion and the mouths thereof are steadied by the means for suspending, sensing means for viewing along a vertical optical axis penetrating said rectilinear portion of the path and for generating a rejection signal in response to detection of each defective container, illuminating means for momentarily illuminating each container as its axis coincides with said optical axis, and ejection means responsive to the rejection signals for ejecting the defective containers.
Claim 10
Dependent Claim
158 words
Apparatus for inspecting containers for defects, each container being of the type having a bottom and a neck presenting an open mouth and each defining an axis passing through its bottom and centrally through its open mouth, which comprises the combination of transport means for traveling the containers along a predetermined path having a rectilinear portion, said transport means including, in said rectilinear portion of the path, means for suspending the containers from the necks thereof so that their axes travel along a line of the rectilinear path portion and the mouths thereof are steadied by the means for suspending, sensing means for viewing along a vertical optical axis penetrating said rectilinear portion of the path and for generating a rejection signal in response to detection of each defective container, illuminating means for momentarily illuminating each container as its axis coincides with said optical axis, and ejection means responsive to the rejection signals for ejecting the defective containers.
