Abstract
A method for X-raying products of a product stream in which products are conveyed in a conveyance direction before the X-raying in a number n lanes parallel to each other. Several adjacent products transverse to the conveyance direction are transferred as a group together into a radiation-protected X-ray room, and the products are rearranged for an X-ray process in the X-ray room such that the shadowing effects during the X-ray process are reduced.
Claims18
A method for use with X-ray inspection of products of a product stream in which the products are conveyed in a number n lanes parallel to each other in a conveyance direction, the method including:
- (a) transferring two or more products as a group together into a radiation-protected X-ray room, the two or more products comprising a respective product from two or more of the n lanes and being spaced apart transversely to the conveyance direction;
- and
- (b) while the two or more products are in the X-ray room, rearranging the two or more products for an X-ray inspection process in the X-ray room, the rearranging serving to change the positions of the two or more products relative to each other in the X-ray room and to increase a spacing between the two or more products, the spacing increase being transverse to the conveyance direction, in the conveyance direction, or both transverse to and in the conveyance direction.
A device for X-ray inspection of products of a product stream in which the products are conveyed in a number n lanes parallel to each other in a conveyance direction, the device including:
- (a) an X-ray room which is radiation-protected with respect to the surroundings thereof, the X-ray room having associated there with an X-ray source and an X-ray detector;
- (b) an inlet of the X-ray room adapted to receive there through into the X-ray room two or more products together as a group, the two or more products comprising a respective product from two of more of the n lanes and being spaced apart transversely to the conveyance direction;
- and
- (c) a rearranging device within the X-ray room for rearranging the two or more products for an X-ray inspection process in the X-ray room, the rearranging being operable to change the position of the two or more products relative to each other in the X-ray room and to increase a spacing between the two or more products, the spacing increase being transverse to the conveyance direction, in the conveyance direction, or both transverse to and in the conveyance direction.
