Abstract: An X-ray inspection apparatus 1 includes a calculation unit that calculates a luminance conversion function of matching or approximating a first output value of a first element 11a based on a first transmission image G1 to a second output value of a second element 12a based on a second transmission image G2 of the second element disposed to face the first element 11a, for each of a plurality of the first elements 11a and a plurality of the second elements 12a; and a correction unit that corrects at least one of the first output value of each of the first elements 11a and the second output value of each of the second elements 12a based on the luminance conversion function calculated by the calculation unit.

Abstract: An X-ray inspection apparatus suppresses anomalies in inspection results caused by the X-ray inspection apparatus being used while an unsuitable setting is in effect. The X-ray inspection apparatus is provided with an inspection unit, a setting unit, a storage unit, an assessment unit, and a notification unit. The inspection unit inspects an irradiated article using detection data obtained by detecting X-rays. The setting unit sets a setting value used in inspection of the article by the inspection unit. The storage unit stores a detection value based on the detection data. The assessment unit assesses, on the basis of the detection value stored in the storage unit, whether or not the setting value set by the setting unit is suitable. When the assessment unit has assessed that the setting value is not suitable, the notification unit issues a notification to indicate that the setting value is not suitable.

Abstract: An inspection device is provided that is capable of counting the number of contained objects of a product in which objects each having a predetermined shape are contained in a package in an overlapping manner. An inspection device 1 includes a total-number calculator 11b that estimates a total mass of a plurality of objects based on grayscale information on a transmission image and calculates the total number of objects by dividing the total mass estimated by a mass of one object.

Abstract: An inspection and sorting system sorts conveyed articles. The system is provided with a conveyance device, an X-ray inspection device, and a sorting device. The conveyance device conveys inspection articles. The X-ray inspection device inspects the conveyed inspection articles. The sorting device has an air sorting mechanism that sorts the conveyed inspection articles in a sorting operation. The sorting device has a sorting information receiving component, a reference signal receiving component, and a sorting mechanism control component. The sorting information receiving component receives sorting information relating to the sorting of the inspection articles based on an inspection result of the X-ray inspection device. The reference signal receiving component receives a fixed-interval reference signal relating to the conveyance by the conveyance device. The sorting mechanism control component controls the air sorting mechanism to execute the sorting operation based on the sorting information at a timing adjusted by the reference signal.

Abstract: Provided is a highly reliable X-ray inspection device having two line sensors, in which accurate inspection results can be obtained even when there is displacement of the mounting position of the line sensors. The X-ray inspection device is provided with a conveyor unit for conveying an article, an X-ray emitter, a first line sensor, a second line sensor, a detection unit, and a corrected-image generation unit. The X-ray emitter emits X-rays to the article conveyed by the conveyor unit. The first line sensor detects, in a low energy band, X-rays that have passed through the article. The second line sensor detects, in a high energy band, X-rays that have passed through the article. The detection unit detects positional displacement of the second line sensor with respect to the first line sensor in horizontal direction and vertical direction.

Abstract: An X-ray inspection apparatus includes an X-ray irradiation unit that irradiates an article with X-rays, an X-ray detection unit that detects the X-rays transmitted through the article, an inspection unit that generates an X-ray transmission image of the article based on a signal output from the X-ray detection unit and performs inspection of the article based on the X-ray transmission image, and a control unit that controls the X-ray irradiation unit and the X-ray detection unit. The control unit executes a first control of controlling the X-ray irradiation unit such that an irradiation output is increased if a detection output of the X-ray detection unit is decreased when the control unit controls the X-ray irradiation unit such that the irradiation output of the X-ray irradiation unit becomes a first irradiation output. The control unit executes the first control in a state where the article is not irradiated with the X-rays.
