This fin tip position measurement method comprises: a jig installation step for installing a jig having a flat measurement surface expanded in a circumferential direction and an axial direction to a tip of at least one among a plurality of seal fins that protrude in a radial direction with respect to an axial line, extend in the circumferential direction, and are arranged in a direction in which the axial line extends; a first measurement step for measuring a distance from the axial line to the measurement surface by scanning the measurement surface with a laser beam; and a first calculation step for calculating a distance from the axial line to the tip of the seal fin by adding a radial dimension of the jig to the distance to the measurement surface.

A method for detecting the angular position of a cap with respect to a bottle is provided. A first image of a cap provided with a first marker and of at least a portion of the bottle with which the cap is associated and which is provided with a second marker is captured. Liquid drops and other possible impurities existing thereon are removed from and/or displaced relative to the cap and bottle portion. A second image of the cap and bottle portion is then captured. The first image and second image are compared to obtain at least one processing which is free from “noise” and interferences due to the liquid drops and on which the positions of the first and second markers can be determined without errors. The relative angular position of the first and second markers are determined. An apparatus suitable to implement the aforesaid method is also provided.

A non-transitory computer readable recording medium has an estimation model according to one aspect of the present invention recorded thereon, and the estimation model is included in a program to be executed by a computer and outputs output data estimated based on input data received. In response to receiving, as the input data, a change over time in an intensity of energy emitted from a sealing part of an object subjected to a sealing process through bonding, the estimation model estimates at least one of whether sealing of the object is good or whether the sealing of the object is defective and outputs an estimation result as the output data, the change over time being calculated based on an intensity of energy emitted at each of a first time point and a second time point that is later than the first time point.

A manufacturing device is used for manufacturing a package including a resin sheet and a predetermined work wrapped with the resin sheet. The manufacturing device includes: a sealing unit that thermally welds overlapping parts of the sheet; and an inspection device that inspects a sealing quality of the sealed portion thermally welded by the sealing unit. The sealing unit makes, by the thermal welding, a thickness of the sealed portion after the thermal welding smaller than a total thickness of the overlapping parts prior to the thermal welding. The inspection device obtains thickness information on the thickness of the sealed portion and determines the sealing quality of the sealed portion based on the thickness information.

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 of visualizing the planeness of a ring surface (16) of a container (14), the method consisting in: lighting the ring surface from above using a peripheral incident light beam having radial rays with specular reflection on the ring surface; and using an optical system (24, 124) to form a plane image of the ring surface on a sensor (18), with an optical geometrical transformation that converts a real height difference (dZ) into an image radial offset (dR) on the image, and the image radial offset (dR) corresponding to a unit real height difference (dZ) is greater than the image radial offset corresponding to a real radial offset of the same dimension.

The invention also provides a device and an installation implementing such a method.

A determination device includes an imager that captures an image of an object subjected to a sealing process by use of an adhesive and that acquires a distribution of an intensity of energy emitted from the adhesive, and a determiner that calculates a change over time in the intensity of the energy emitted from the adhesive based on a first distribution indicating the distribution acquired from an image captured by the imager at a first time point and a second distribution indicating the distribution acquired from an image captured by the imager at a second time point later than the first time point and that determines the quality of sealing based on the calculated change over time.

An inspection line comprises: at a finish inspection station, a finish inspection installation capable of detecting without contact, by light rays, check-type defects in the neck of the containers; at a base inspection station, a base inspection installation capable of detecting without contact, by light rays, check-type defects in the base of the containers; and at a radiographic measuring station, a radiographic installation for automatically measuring linear dimensions of at least one region to be inspected of containers. The three installations are each arranged at stations distinct from each other along a trajectory of displacement of the containers. In each installation, a section of the transport device ensures, in the inspection area of the installation, the transport of the containers along a rectilinear portion of the trajectory (T) in a horizontal conveying plane (Pc) perpendicular to the central axis of the containers.

The invention relates to a method, a device and an inspection line for determining the three-dimensional geometry of a container ring surface, including the formation, by two optical systems (24, 24′), of two images of the ring surface of the container, according to two peripheral observation fields having a first and a second observation elevation angle (γ1, γ2) different from each other.

The present disclosure relates to a system and method to measure the quality of the inspection process by assigning a score to indicate the level of integrity of a seal of a package in a packaged product. The packaged product is run through an inspection machine, e.g., an X-ray machine, to capture an image. Image processing techniques are used to identify the seal region from the image, which is then divided into a number of sub-regions. Seal scores for each sub-region is calculated using a mathematical framework that takes into account existence (or non-existence) of certain types of defects in the sub-regions. A report is generated to display the results of the seal score determination algorithm to the entity that requested the seal score.
