Can inspection machine
Sencon's new X-Seam analyser is a can inspection machine that uses X-rays
to generate images of a filled can at a number of points around the seam.
An image processor measures each of these points to the nearest 0.001mm,
and a report is produced, based on pre-determined standards. It takes
about 70 seconds to inspect one can in this way.
The motion control elements were supplied by Trio Motion Technology and
comprise MC202 Motion co-ordinator, two CAN 16 I/O modules and one CAN
analogue input module. These control input and output can conveyors a
vacuum lift transfer system and a chuck assembly that clamps the can and
moves it towards the X-ray head. Apart from the chuck, which is moved by
a stepper motor, all other movements are pneumatically actuated.
