Can Vacuum Tester

in Inspection Equipment

This machine is ideally installed directly in the production lines. It has an extremely simple operating principle for the total elimination of defective cans (pin holes,dented flanges,cracked flanges,cracked flanges,cracked welds,etc.).

Standard vacuum is applied to the cans and those found faulty will be automatically rejected. Can height can be set with simple adjustments in about 5 minutes. Changeover of diameter is also possible by means of tool kits (setting in 50 minutes).

The in-feed belt feeds cans to the rotary testing unit with 20, 40 or 52 heads. As each head completes a full revolution, it depressurizes the can being tested to a standard pressure value.

Any variation detected in this depressurization mean there is a leak in the can, so the machine produces an electronic signal or ejects the can. After testing, the good cans are reinserted in the production line.

The machine is equipped with a special pneumo-electronic transducer unit for detecting microholes.

This device displays on the electronic board the number of the pocket in which a defect has been found.

Set up is done automatically using a special soft key installed on the same panel.

The control panel controls and monitors the various operating phases of the machine, providing a rapid set-up of reference parameters and display of the current pressure values and reject counts for each rotary head.
