Fixed 2D code scanner with OCR, pattern matching and print quality inspection capabilities MVF-500 / MVF-500C

As well as reading barcodes, it is now possible to read character printouts such as expiry dates, lot numbers and manufacturing symbols.
The character recognition function enables checking of production dates and expiry dates due to date setting errors and the recording of additional information such as lot numbers and production symbols as traceability information.

New reading capability for damaged symbols that were difficult to read and unreadable by conventional machines, such as colour irregularities within the symbol, low contrast and distant cells. Cell squashing, lateral stretching and smearing can also be automatically restored during reading without pre-setting using a new algorithm.

By checking the print quality according to standardised rules, stable barcode reading is possible not only for the company itself, but also for the entire supply chain, including the delivery destination. In addition, in-line print quality monitoring can provide immediate warning of print defects or changes in the age of the marking equipment immediately after marking. Quality can be inspected at the same time as the barcode is read, according to the parameters of the ISO 15415 and AIM DPM 2006-1 international standards.
The inspection results can be output not only as an overall judgement as required by ISO and AIM, but also as a judgement by arbitrarily selecting the inspection parameters that suit the actual operation.

Readability cannot be judged solely on the basis of catalogue specifications measured in the best position. The “reading depth” is also a very important factor.
The optimum combination of a newly developed sensor and lens and a new type of illumination ensures high reading performance over a wide range of focal lengths.

The MVF-500C also offers excellent reading performance over a wide range of conditions, including reading distance, symbol density and workpiece material colour, with a free choice of C-mount lenses.

Eight patterns of reading conditions are preset in the scanner, based on an analysis of print patterns that are considered difficult to read.
If the scanner cannot read with active tuning, it automatically selects the best reading setting from the eight patterns for optimum reading.
Equipped with an intelligent mode that remembers the selected reading settings and starts reading the next time!
The settings of up to 8 patterns can also be changed at will.

The MVF-500 allows multiple scanners to be linked together, making it ideal for applications where a larger area needs to be covered or where barcodes are printed in multiple directions.
In addition, the scanner itself can be reconfigured to act as either a master or slave, eliminating the need for a keypad to control multiple units. In an emergency, it is easy to switch to an alternative unit.

Reading parameters can be set automatically in the simple setting mode, making it easy for anyone to set up for symbol reading. Detailed parameter settings can also be made in the detailed setting mode, which covers all configurable functions.

Displays the image read from the scanner.
Adjustments – Adjustments can be made by following the on-screen instructions while viewing the image. Adjustment parameters can be saved as a file on the computer.

While checking the image on the live screen, change the displayed parameter items so that the corresponding image is displayed. If you change the shutter speed, analogue gain, digital gain, black level, etc., the changes are reflected on the live screen in real time.

The print quality of the symbol data read can be visually inspected item by item. (Overall Quality / Contrast/ Modulation / Fixed Data Damage / Decoding / Axis Irregularity / Grating Irregularity / Unused Error Correction)

ViT is the software included with the MVF Config for configuring and checking the readings related to OCR.
With simple mouse and other operations, you can rewrite and save configuration parameters related to the OCR of the scanner; you can save ViT configuration parameters to your computer as a file or read configuration parameters from a saved file.

On-screen confirmation of symbol decoding results①, character reading results②, symbol print quality, collation judgement and overall judgement. A log of the reading data can be saved in a text file.
