The MVS-OCR2 character recognition vision sensor can be used to inspect expiration dates printed on pouches with red, gold, or silver gloss.
The superior character extraction performance of the MVS-OCR2 enables recognition without having to change settings even for targets with different background colors.
With the addition of a flat dome lighting made by CCS Inc., the light source can be applied more evenly, ensuring stable inspection even for uneven or glossy workpieces.

The OCR Vision Sensor, MVS-OCR2, checks an encoded date and time in a string, in addition to an expiration date.
A string for quality control including date and time can be recognized by automatic update using the calendar function.
Change of date or time to be recognized from production schedule requires no change in camera settings.

MVS-PM-R of the pattern matching camera checks the presence of the back side label, and inspects the expiration date on the label with the OCR camera MVS-OCR2.
The controller MVS-DN-E can connect up to three cameras.
Since only one controller is required, it is possible to construct an inspection system with low cost.

Checking shelf life printed on the packages in small packaging machine by character recognition feature of the OCR vision sensor MVS-OCR2.
By attaching the 90 ° side view mirror to the tip of the lens, it is possible to install to a narrow space between the packaging films.
It realizes to install on a machine that could not install the camera due to space problem.

OCR vision sensor MVS-OCR2 can check existence of stealth invisible printing on packages.
The stealth ink used for those invisible printings that can be visible when exposed to ultraviolet lighting OPDB series. The combination with MVS-OCR2 and ultraviolet lighting OPDB series makes it possible checking existence of stealth invisible printing which is not required for consumers.

OCR vision sensor MVS-OCR2 can check if the shelf life is printed correctly or not on the carton box.
Print inspection of low contrast printings on the carton box is also possible by utilizing its high performance ability of extracting characters. MVS-OCR2 can recognize "+", which would be used for a mark that means produced at a factory, as a character not just detecting existence of a mark.

Checking marking on the metal parts by CVS4-R series.
CVS4-R series has a function that counting up the lot number to verify.

Print inspection on the sun-roof glass plate by CVS4 series.
It can check if the glass plate is correct one or not by print inspection.

Character recognition cameras can be used to check expiration dates printed on cartons using PC coders.
Judgments based on the number of characters (Character Count function) are effective when printing is uneven.

Print inspection on the molded plastic by MVS-OCR2.
Not only rejecting NG parts but also you can get how the vision sensor recognized the printing by getting ASCII code of the characters from the vision sensor.

Checking existence of characters on metal surface by MVS-PM-R.
Generally, standard vision sensor won't be able to detect existence of characters on metal surface especially if it's hair-lined. MVS-PM-R's "stain" function detects existence of characters on metal surface stably.

Print inspection on the date code and lot number printed on packaging film.
MVS-OCR2 has 8 times better resolution than conventional model so it can detect small and wide printing stably.

Print inspection of white characters on colored pattern by MVS-OCR2.
It can recognize color of the characters so white characters are also able to be recognized correctly by MVS-OCR2.
Not only date code but also lot number can be inspected stably.

Print inspection on packaging film by all in one OCR vision sensor CVS4 series.
It has calendar built-in so it can check date code over night production even if the date code changes at mid night.

Checking existence of characters printed on package by MVS-OCR2.
It can count number of characters on package even if the package got wrinkled because you can setup the threshold of number of characters like N +/- X.

Print inspection on the sealing machine by CVS4-R series.
It is compact all in one vision sensor so you can install in a small machine.

Print inspection on the pillow packaging machine by MVS-OCR2.
It has 32 banks so it can be used for up to 32 different printing.

Print inspection on the colored pattern by MVS-OCR2.
It can detect color of characters so even if the background is colored pattern, it can recognize characters stably.

Print inspection for invisible fluorescent ink printing is possible utilizing ultra-violet LED lighting and mega pixel character recognition vision sensor MVS-OCR2.

Print inspection on low contrast printing for example black ink on dark blue base is possible by MVS-OCR2.
By high ability of extraction of colors on MVS-OCR2 enables print inspection on low contrast printing.

MVS series can store NG images in the controller so you can check why it's rejected later.

Existence of characters printed at bottom of ampoule container can be checked by MVS-PM-R.
"stain area" function can be utilized for this application then, low contrast printing can be detected stably.

Two different accuracy inspection is possible on MVS-OCR2. Severe inspection on date and rough inspection on the lot number for example.
Generally, it will be OK when the lot number is not printed so clearly if it can be read without problems. Although, date must be printed clearly and correctly.

When the thickness of the printing deviated, you can check the printing by counting character number instead of recognition of characters.

At the bottling line, water splashes may occur sometime to keep production line clean. In that case, CVS4-R can be used without problems because it's IP67 protection rating.

Print inspection on glossy surface like aluminum vapor deposition film by character recognition camera MVS-OCR2.
Even if printed characters on glossy material, MVS-OCR2 will be able to detect characters stably.

Inspection of shelf life on multiple packages at one time by print inspection camera MVS-OCR2.
MVS-OCR2 can inspect up to 4 inspection window at one time. Narrow the iris of the lens so that the depth of focus get longer. Then, it can get clear image of multiple packages in FOV even if the distance of the object is different.

By counting function of MVS-OCR2 (Character recognition vision sensor), existence of Kanji character can be detected.
By separating printed part into two part, one is Kanji part and another is numeric part, assigning inspection window for each part then set counting character number function for Kanji part and character recognition function for numeric part. Two part of the printing can be inspected at one time in this way.

Character recognition vision sensor MVS-OCR2 has 8 times bigger resolution than conventional model so it can recognize printing by laser marking even if the line is very narrow.

MVS-OCR2 can recognize characters printed on colored pattern by recognizing color of the characters stably.

Because of high resolution of MVS-OCR2 camera, 8 times better than conventional model, it can have wide FOV so it can recognize characters printed on individual packaging at deviated position on the conveyer.

Print inspection of production date and shelf life printed on the carton box at a time is possible because MVS-OCR2 can set wide FOV (Field Of View) thanks to its mega pixel image sensor.
You don't have to invest for two cameras so it's cost effective.
