摘要： An inspection system for a drug container is provided to identify foreign matter, such as particles or fibers, within the drug container prior to filling with a drug. The system includes a camera device aligned with an axis of the drug container and captures a series of images of an interior surface of a sidewall of the drug container while the robot causes relative movement between the drug container and the camera device along a linear path. Atypical lighting, which improves contrast between particles and the background in images is employed to aid detection. A control circuit then processes the series of images to identify foreign matter within the drug container.

摘要： Apparatus for detecting cracks in optically transparent articles e.g vials, comprising a mount for the article, a light source to direct light at a mounted article, an optical detector positioned to receive light from the light source passed through the article and to generate an electronic signal responsive to received light, first and second (analyzer) polarizers such that light from the light source passes through the first polarizer then through the article, then through the second polarizer on its path to the optical detector, with an optical wave plate positioned between the mount and the second polarizer, and an image processing system to process the electronic signal generated by the optical detector and to indicate the presence or absence of a crack in the article supported on the mount. A method of crack detection using the apparatus is also provided.

摘要： The present invention relates to a testing method and a corresponding testing system, for example for testing workpieces (2), which are provided for producing containers, in particular beverage bottles, and which can consist of a basic body and a barrier layer that is at least partially applied to the basic body, whereby the workpieces (2) are transported into a receiving vessel (4) by means of a transport device (3), and whereby an image of the workpieces (2) is generated by means of a capturing device (6) and is transmitted to a processing device for testing, wherein the workpieces (2) are led into the receiving vessel (4) upon leaving the transport device (3), whereby the image is generated between the departure from the transport device (3) and the receiving vessel (4) and wherein the image is processed by the processing device in such a way that the quality of the basic body and/or the quality of the barrier layer of the workpieces (2) is tested in order to detect defective workpieces (2). The same testing system and the same testing method can also be used to count the workpieces (2).

摘要： Systems and methods are provided for determining a thickness of a material or an article of manufacture thereof such as a wall thickness of a plastic container or plastic bottle during manufacturing. In some embodiments, for example, a measurement system can include a light source disposed adjacent to a production line for plastic bottles. The light source can be configured to transmit light of a known frequency through the plastic bottles. A camera can be disposed opposite the light source. The camera can be configured to receive the light transmitted through the plastic bottles. An optional trigger, when present, can be configured to coordinate timing of the camera and the light source. A computer can be configured to determine wall thicknesses for the plastic bottles by an experimentally determined correlation between the light received by the camera and a known absorbance spectrum of the material forming the plastic bottles.

摘要： An inspection system having a light source able to illuminate a transparent cylinder, a mask able to block at least part of the light from the light source, the light source and the mask arranged such that, when the transparent cylinder is positioned in the system for inspection, the light source, the mask and the transparent cylinder are substantially aligned along an inspection axis perpendicular to the longitudinal axis of said transparent cylinder and the mask is interposed between the light source and the transparent cylinder to prevent illumination of a first portion of the transparent cylinder having a width smaller than the diameter of the transparent cylinder while allowing illumination of a second portion of the transparent cylinder, the mask configured to provide a contrast with a particle present in the first portion of the cylinder and illuminated by light refracted by the second portion of the cylinder.

摘要： An inspection system for detecting a particle in a transparent cylinder having a longitudinal axis and a diameter includes a light source able to illuminate a transparent cylinder, a mask able to block at least part of the light coming from the light source, the light source and the mask being arranged such that, when the transparent cylinder is positioned in the system for inspection, the light source, the mask and the transparent cylinder are substantially aligned along an inspection axis perpendicular to the longitudinal axis of said transparent cylinder and the mask is interposed between the light source and the transparent cylinder so as to prevent illumination of a first portion of the transparent cylinder having a width smaller than the diameter of the transparent cylinder while allowing illumination of a second portion of the transparent cylinder, the mask being configured to provide a contrast with a particle present in the first portion of the transparent cylinder and illuminated by light refracted by the second portion of the transparent cylinder.

摘要： A method and device detect defects in the closure of encapsulated vials. The method includes scanning a profile of the capsule and of the vial using a profilometer, thus obtaining a point cloud. From the point cloud obtained, calculating at least one of the following parameters: diameter or radius of the closure circumference of the capsule; angle of intersection between the lower skirt and the side of the capsule; length of the lower skirt; and/or a distance from the end of the lower skirt to the neck of the vial. The method determines whether any of the parameters calculated in the previous step exceeds a predetermined value. The device detecting defects in the closure of encapsulated vials includes a profilometer configured to scan a profile of the capsule and of the vial and a control device configured to execute the method.

摘要： The invention provides a device for optically inspecting high temperature glass containers (2), the device comprising a lighting system (7) having a light-emitting surface that is adapted to emit both: a “flash” first light flux during a flash duration of less than 1 ms and at a wavelength longer than 650 nm; and also a “bottle-scanning” second light flux having wavelengths shorter than 650 nm and for a duration of not less than 2 s, the lighting system (7) being controlled: to emit the flash light flux so that the camera can take images of each container while back-lit by said flash light flux; and to emit the “bottle-scanning” light flux that is perceived by a human eye as being continuous.
