Sencon
X-Seam Double Seam Analyser |
| |
| |
A
revolutionary can inspection machine offers exceptional programming
flexibility and low maintenance costs through the use of a
Trio Motion Technology Motion Coordinator.
The
X-Seam Double Seam Analyser from Sencon uses X-ray technology
to inspect the vital joint between filled food or beverage
can ends and sides, eliminating the need to perform manual,
destructive testing. A sophisticated image processor linked
to the X-ray camera measures each critical point and produces
a report based upon pre-determined standards. Typically, measurements
are made to 0.001mm and have excellent “R & R”
standards of better than 20%. |

Sencon
chose an MC202 Motion Coordinator, 2 CAN 16-I/O modules and
one CAN Analog Input module to control the entire mechanical
elements of the X-Seam Analyser. These consist of two can conveyors,
a vacuum lift mechanism which moves cans from the input conveyor
to the measuring point and then removes them to the output conveyor,
and a chuck assembly which clamps the can firmly and moves it
to the X-ray generator head. |
|
| During
measurement, the chuck assembly is rotated by a stepper motor
to four accurately pre-set positions, providing four images
of each can seam for analysis. |
| |
A
second stepper motor drives the ball screw to move the chuck
into position. All other movements, including vacuum pick-up
and can transfer, are actuated pneumatically using limit switches
and controlled by the MC202. The whole assembly is therefore
completely “stand-alone”, needing only the manual
input of a start signal to begin operation and an indication
of how many cans are to be tested. |
