Abstract
Method and installation for manufacturing and inspecting metal containers. The method includes extruding a metal disk to form a metal container having a cylindrical body with a side wall, a base, and an open end opposite the base. After the metal container is formed the thickness of the base is determined by arranging the base between an X-ray emitter and an X-ray receiver and emitting X-rays from the X-ray emitter to the X-ray receiver through the base. The thickness of the base is determined based on the intensity of the X-rays absorbed by the base.
Claims20
A method of manufacturing and inspecting a metal container, the method comprising:
- extruding a metal disk by use of an extruder to form the metal container, the metal container having a base, a cylindrical body with a side wall, and an open end opposite the base;
- and
- determining a thickness of the base after forming the container by locating the base between an X-ray emitter and an X-ray receiver and emitting X-rays from the X-ray emitter to the X-ray receiver through the base, each of the X-ray emitter and X-ray receiver being located outside the container with the X-ray emitter facing a first side of the base located inside the container, the X-ray receiver facing a second side of the base located outside the container, the determining of the thickness of the base including emitting X-rays of a first intensity from the X-ray emitter through the open end of the container towards the first side of the base, the X-rays having passed through the base and received by the X-ray receiver having a second intensity less than the first intensity, the thickness of the base being determined by the first and second intensities.
An installation for manufacturing and inspecting metal containers comprising:
- an extrusion press for extruding a metal disk to form a metal container, the metal container including a cylindrical body with a side wall, a base, and an open end opposite the base:
- an inspection unit for inspecting the metal container and determining the thickness of the base, the inspection unit including an X-ray emitter and an X-ray receiver that are arranged to respectively face first and second opposite sides of the base when the container is located in the inspection unit, each of the X-ray emitter and X-ray receiver arranged to be located outside the container when the container is located inside the inspection unit, the X-ray emitter configured to emit X-rays of a first intensity through the open end of the container towards the first side of the base, the X-ray receiver configured to receive X-rays of a second intensity having passed through the base;
- and
- a control unit configured to determine the thickness of the base based on the first and second intensities.
