CCD with no price premium against the
laser
CCD camera technology is proving increasingly viable for companies wishing to invest in high performance bar code reading for 1D and 2D symbologies.
CCD camera technology is proving increasingly viable for companies wishing to invest in high performance bar code reading for 1D and 2D symbologies Accu-Sort is at the forefront of this technology and its latest introduction - the AV3700 - certainly brings a highly cost-efficient and flexible alternative to UK industry

Dell eliminates the potential of packing errors
Thanks to its investment in a computer-aided pick-to-light system however, Dell's 'top box' contents accuracy is exceptionally high.
Flexible bar code scanner designed to adapt
Thanks to the Adaptascan's autofocus capability and WindowsT-based configuration software, changes in focus, scan pattern, label format and communication requirements can be made on-line.
For a similar price to a top-end laser based solution, the solid state AV3700 takes linear scanning in its stride, allowing the user to incorporate 2D code reading applications as and when the need arises.
Superior performance is another main benefit.
The Accu-Sort camera typically cuts the no-read rates of even the best laser systems by 50%.
The modular design of the AV3700 has resulted in a small, lightweight camera assembly.
As it weighs just 16kg, it is easily fitted over a conveyor belt for side- and bottom-read applications, by a single technician.
Furthermore, the camera requires no adjustment once installed.
The camera is particularly effective at reading small bar heights and as it takes a complete picture of the product or carton, code orientation is not an issue.
In addition to bar code reading, the AV3700 can also be used for OCR operations and videocoding which allows the automatic sorting of packages without bar code labels.
A new low-power, low heat, high-intensity LED-based illumination option offers the same image quality and read rate performance as the standard sodium vapour lamps and eliminates glare for side and bottom reading.
Separate external 400W sodium vapour illumination is also available for long range and high resolution applications; the unit provides 24,000 hours MTBF.
The camera has a scan rate of 10,000 scans/per second and is able to operate at speeds of up to 3m/second; read range is 900mm.
A typical system comprises camera head, decoder - either desktop Pentium PC, or Accu-Sort's own industrial PC - and any additional lumination that may be needed.
Other options include accessories such as tachometers to measure belt speed and light curtain to detect the product and determine its height.
Tunnel configurations of the AV3700 may also be specified which allow six faces of the product to be scanned by five cameras.
The new Accu-Sort AV3700 is expected to prove particularly popular for high speed parcel sorting, wholesale and mail order distribution and parcel OCR reading.
