Question

Identify and describe a commercial vision system capable of reading a Unique Device Identifier (UDI) code printed on the end of cans containing food products such as green beans. The cans travel down a conveyor at speeds of 600 cans/minutes. The vision system must identify any and all rogue cans, and send an appropriate signal to a device which will eject the can from the conveyor stream.

Answer 1

UDI ( Unique device identifier )

UDI is simply a device identifier code in any form so that the device or the product containing UDI can be easily traced to its manufacturing roots and other information about the product is obtained .

Commercial vision system -

A commercial system capable of reading UDI works is IVS (Industrial vision systems) which combines with AIDC (Automatic identification and data capture ) which is used in the process of inspection .

It works by the combination of the following process -

• Optical character recognition
• Optical character verification
• Code reading

In which the UDI is checked during the whole process of production to conform to the recognises FDA standards.

The system here identify all the capable and rogue cans and send the signal to the device which will eject the can for conveyor stream .
