Pharmaceutical
Machine Vision Application
Project
Introduction: As the Food and Drug
Administration (FDA) bar-code regulation raises packaging
standards, drug manufacturers are turning to increasingly
sophisticated machine vision inspection solutions for optical
character verification to inspect human-readable data such
as the date, lot code, and expiration date on drug labels
as well as reading bar code, logos and directions.
System
Requirements: A
typical blister pack, measuring only 3 x 5 inches, may hold
as many as 20 tablets, and drug companies are often looking
to simultaneously read each RSS / CS code on as many as four
blister packs at line speeds of up to 150 packs per minute.
This demand poses a challenge for modern 2-D imaging products
(array-based CCD products), which lack the resolution to read
all the cods in a single field of view. Any solution supported
by array-based CCD product often requires as many as 10 cameras
to meet the desired field-of-view and line speed requirements
Project
Implementation:
IPPC-6172F:
17" SXGA TFT LCD Celeron M Fanless Industrial Panel
PC with 2x PCI Slots
System
Description: The
most efficient solution involves a line-scan camera, a frame
grabber and Advantech’s IPPC-6172F.
- A single
2K line-scan camera can easily capture the required field
of view with more than enough resolution, 3 pixels per element
with a 6-inch-wide field of view, to enable pharmaceutical
companies to read every code.
- Standard
high performance Industrial Panel PC delivers, controls
and stores adequate image and information for inspection
and printing.
Conclusion:
The
IPPC-6172F provides an excellent interface for this solution,
because it can also provide active mimic diagrams, alarms,
event logs and more. The simplicity of the display allows
operators of all knowledge levels to understand UPS status
and operation at a glance, limiting operator errors.
After
implementing, the solution also provided the following benefits:
- Increased
Reliability
- Quicker
Time to Market
- Reduced
Cost of Ownership
- Increased
Security
- Accessible
