X-ray inspection device
An X-ray inspection device includes a conveyor, an X-ray irradiation unit, an X-ray detection unit, an inspection unit configured to inspect an article on the basis of an X-ray transmission image, a housing accommodating the X-ray irradiation unit and the X-ray detection unit, a cool air blower configured to cool air inside the housing and guide cool air to the X-ray detection unit via a duct, a monitoring unit configured to monitor a state of the cool air blower, and a control unit configured to stop the flow of air to the X-ray detection unit when an anomaly of the cool air blower is detected by the monitoring unit.
1 . An X-ray inspection device comprising:
a conveyor configured to convey an article;
an X-ray irradiation unit configured to irradiate the article conveyed by the conveyor with an X-ray;
an X-ray detection unit configured to detect the X-ray transmitted through the article;
an inspection unit configured to generate an X-ray transmission image from the X-ray detected by the X-ray detection unit and inspect the article on the basis of the X-ray transmission image;
a housing accommodating the X-ray irradiation unit and the X-ray detection unit;
a cool air blower configured to cool air inside the housing and guide cool air to the X-ray detection unit via a duct;
a monitoring unit configured to monitor a state of the cool air blower; and
a control unit configured to stop the flow of air to the X-ray detection unit when an anomaly of the cool air blower is detected by the monitoring unit.
2 . The X-ray inspection device according to claim 1 ,
wherein the control unit stops the irradiation of the X-ray by the X-ray irradiation unit and the detection of the X-ray by the X-ray detection unit when an anomaly of the cool air blower is detected by the monitoring unit.
3 . The X-ray inspection device according to claim 1 ,
wherein the control unit continues the conveyance of the article by the conveyor when an anomaly of the cool air blower is detected by the monitoring unit.
4 . The X-ray inspection device according to claim 1 , further comprising
a discharge unit configured to discharge water generated inside the housing to outside of the housing,
wherein the cool air blower cools the air inside the housing by internal air circulation to generate the cool air, and
the discharge unit includes a sealing portion and/or a check valve, the sealing portion and the check valve being configured to prevent external air from flowing into the housing.
5 . The X-ray inspection device according to claim 1 , further comprising
a blower configured to blow the cool air supplied from the cool air blower to the duct,
wherein the control unit stops operation of the blower when an anomaly of the cool air blower is detected by the monitoring unit.
