摘要： An apparatus for checking tyres has at least one check unit at least two consecutively placed check stations defining a check path such that each check station is traversed in one cycle time and by pitches by each tyre to be checked. Each check station includes: a support device for one tyre at a time housed in the respective check station, high-definition image acquisition systems of a surface of the tyre, and movement devices. The high-definition image acquisition systems have systems for acquiring high-definition two-dimensional and three-dimensional images. Only one of the at least two check stations has all the high-definition three-dimensional image acquisition systems of the check unit.

摘要： An apparatus for checking tires described as a linear camera having an objective line lying on an optical plane; a first, a second and a third light source for emitting respectively a first, a second and a third light radiation; a command and control unit for selectively activating at least one from among the first, second and third light source and activating the linear camera in order to acquire a two-dimensional image of a linear surface portion of the tire synchronously with the activation of the first, second and third source. The first and second light source lie on opposite sides of the optical plane. Furthermore, the first, second and third light source include each one or more sub-sources each having a respective main extension direction parallel to the optical plane and the distance of the sub-sources of the third light source from the optical plane is less than the distance of the first and second light source from the optical plane.

摘要： A method for checking a tyre for vehicle wheels in a checking station. The checking station includes a background with a support surface lying on a plane perpendicular to a reference axis, an image acquisition apparatus to acquire an image of the tyre arranged with a first outer lateral surface in contact with the support surface and a second outer lateral surface facing the image acquisition apparatus, an illumination system and a computer for generating a working image from the acquired image. The image acquisition apparatus, the illumination system and of the background are arranged to generate a contrast, in the working image, between the entire second outer lateral surface of the tyre and an area circumferentially surrounding the tyre.

摘要： The invention relates to a method and line for checking a tyre (2) for vehicle wheels in which it is provided to determine whether the tyre (2) is made according to a known model among a plurality of known models. If the tyre (2) is made according to a known model, the tyre (2) is inspected to search for any manufacturing defects by acquiring data representative of at least part of the surface of the tyre (2) through a set of image acquisition devices (282) set according to a setting associated with the known model of the tyre. If the tyre (2) is made according to an unknown model, the following steps are carried out in succession: •acquiring a first profile (300) of the tyre (2), wherein the acquisition of said first profile comprises acquiring at least a first part (301, 302) of the first profile (300) through first profile-acquisition devices (280) arranged according to predetermined positions; •determining a setting for second profile-acquisition devices (278) based on the first profile (300) acquired; •acquiring a second profile (400) of the tyre (2) through the second profile-acquisition devices (278) set according to the respective determined setting; •determining a setting for said set of image acquisition devices (282) based on the second profile (400) acquired; •cataloguing said unknown model as a known model and adding it to said plurality of known models, associating the setting thus determined therewith.

摘要： A method and apparatus for checking tyres in a tyre production line. The method includes alternately illuminating, with a first and second grazing light radiation, a surface portion of the tyre and respectively acquiring a first and second two-dimensional digital image of the illuminated surface portion. For each point of the surface portion, the respective overall light power of the first and second light radiation incident at the point respectively comes from two half-spaces that are opposite with respect to an optical plane passing through the perpendicular to the surface at the point; and comparing the first and second image to obtain information on an altimetric profile of the surface portion.

摘要： Device and method for analysis of tyres are presented. The device includes a support frame, a flange, and first/second image acquisition systems. According to one aspect, the first acquisition system is two-dimensional and includes a first camera having a first optical axis, a first focal plane, a first focal point, and a first depth of field, and a first illumination system that illuminates around the first focal point. According to another aspect, the second image acquisition system is three-dimensional and includes a second camera having a second optical axis, a second focal plane, and a second depth of field, and a second illumination system. A translation plane, substantially orthogonal to the first optical axis, is defined by the first focal point, and an intersection between the second optical axis and the second depth of field.

摘要： A system for controlling a parameter relative to the quality of a tire being processed includes at least one system for detecting a parameter relative to one or more tires being processed. A control unit is programmed for comparing a succession of values of the parameter by comparing each value with at least one discard threshold and preferably with at least one warning threshold. The discard threshold divides a discard interval from an acceptable interval. The warning threshold belongs to the acceptable interval and defines one or more warning intervals. The control unit is also programmed for controlling the trend of the succession of values with respect to the discard threshold. A method for controlling quality of production of tires.

摘要： A method for controlling the manufacturing of tires for wheels of vehicles includes: extracting a cured tire from a curing station, in which the cured tire has accumulated heat during a curing process; and verifying the presence of possible defects or imperfections in that cured tire. The verification includes detecting first electromagnetic radiations representative of a heat emission from different portions of the cured tire while the cured tire frees the accumulated heat; providing at least one output signal representative of the first electromagnetic radiations detected to allow an analysis of the cured tire and to verify the presence of the possible defects or imperfections. A plant for the manufacturing of tires for wheels of vehicles is also described.
