Described herein are various technologies related to inspecting transparent containers for both opaque and transparent defects. An emitter is configured to direct a color gradient through a sidewall of a transparent container, such that color of light that passes through the sidewall varies across the sidewall. A camera is configured to capture an image of the sidewall of the transparent container while the color gradient passes through the sidewall of the container. A computing system receives the image and determines whether the sidewall of the container includes either an opaque or a transparent defect based upon the image.

A device, system and method for inspecting containers by detecting a reflected light beam are described. A light source emits a directed light beam through a container. One or more cameras are oriented to detect and measure portions of the directional light beam reflected by one or more fragments contained within the container.

The invention relates to an optical computing method and system for inspecting in through light a container (12), in which: the container is illuminated by elementary emitting areas each emitting a polarized emitted light with an emitted polarization property of interest that varies according to a law of periodic variation which, over a primary period (T1), follows a triangular variation as a function of the position of the elementary emitting area along the primary direction (D1); digital images are acquired, with at least one camera, with interposition of a linear analyzer (30(n,k); 30.1, 30.2) having a given axis of polarization (Ak) for a partial digital image ((Ipk.m); at least one primary raw refraction image (IR1) is calculated, each pixel of which is representative of the refraction undergone by the light.

The system advantageously includes a two-dimensional matrix (16c) of liquid crystal cells.

A device includes a camera, which captures images of moving objects, lighting units, and a controller. The camera captures recordings of the moving objects in series during transportation on the conveyor, so that a first recording of the object in a first position and a second recording of the object in a second position are obtained. The first and second positions of the object differ by the movement of the conveyor by a corresponding offset. The illumination units are composed of a dark-field illumination unit and a bright-field illumination unit, which are controlled synchronously with the camera by the controller such that the first recording generates a first contrast by a first specific control of the dark-field illumination unit and bright-field illumination unit, and in that the second recording generates a second contrast by a second specific activation of the dark-field illumination unit and bright-field illumination unit.

The invention relates to a method and device for detecting the edge profile of bottles or similar containers that are moved past a measuring and/or receiving region of a measuring and/or receiving system, using at least one opto-electric receiver on one side of the measuring and/or receiving region and using at least one light-emitting device on the side located opposite of the receiver in the measuring and/or receiving region.

An apparatus and methods of decorating a metallic container are provided. More specifically, the present invention relates to apparatus and methods used to provide a decoration on a predetermined portion of a metallic container body. The decorator includes a sensor that senses decorations on metallic containers. A control system receives information related to the sensed decorations from the sensor and then determines if the decorations at least meet predetermined color, density, thickness, orientation, and consistency targets. The control system can automatically adjust elements of the decorator to correct a deficient decoration. In one embodiment, the control system can automatically adjust ink blades associated with a plurality of inking assemblies of the decorator to adjust the color, density, orientation, positioning, and consistency of decorations transferred to the metallic containers. In another embodiment, the control system can adjust a position of an inking assembly, an ink roller, a plate cylinder, a printing plate, a blanket cylinder, and a transfer blanket of the decorator.

The apparatus for inspecting containers comprises an illumination device, a rotation device and a capturing device. The illumination device is configured to illuminate an illumination region alternately with different illumination patterns, which comprise at least a first illumination pattern and a second illumination pattern. The illumination device is configured to illuminate the illumination region with the first illumination pattern in first time windows and to illuminate it with the second illumination pattern in second time windows. The rotation device is configured to rotate a container with a bottom and with a sidewall about an axis of the container in such a way that at least a section of the sidewall passes through the illumination region along a rotational direction. The capturing device is configured to take a photo of the illumination region at least in each first time window and in each second time window.

A station for detecting glass disease-type defects in a segment of containers includes: a non-deformable support on which the projectors and the imagers are mounted by a complete connection so as to fix beam directions of the projectors and the optical axes of the imagers; several sets of projectors each include at least six projectors whose beam direction is tangent to a cylinder with a diameter included in a determined range of diameters; an electronic system configured to inspect the containers falling within all of the ranges of diameters, such that during inspection of the containers whose segment diameter to be inspected is included in the range of diameters of a set, the electronic system ensures acquisition of at least six images of each container when it passes through the inspection area by selectively activating the at least six imagers simultaneously with the associated projectors of said set.

The invention relates to a method for inspecting containers, comprising: providing a first source of light illuminating the containers, said source being composed of a plurality of elementary light sources that are controlled so as to define at least three illumination zones (S11); providing at least three image sensors (C11, C12, C13); acquiring at least one image of the container illuminated by an associated illumination zone, the elementary light sources of the illumination zones (S11) being controlled so that: the at least three illumination zones (S11) associated with the image sensors have identical angular widths (L11); the at least three illumination zones (S11) associated with the image sensors have symmetric angular widths (L11); and at least two angularly neighbouring illumination zones have a common illumination portion (S112).

The disclosure relates to a method for optically inspecting containers, wherein the containers are transported to an inspection unit with an illumination unit and with a camera, wherein the illumination unit emits light from a flat light-emitting surface, wherein the light is transmitted or reflected via the containers, wherein the camera captures a respective at least one of the containers and the light transmitted or reflected via same in at least one camera image, and wherein the at least one camera image is analysed by an image processing unit for intensity information in order to identify foreign bodies and/or defects in the container.
