ASIR 3 – Q/C System with a quick ROI

5 comments

ASIR stands for Automatic Signature Image Recognition. (ROI is less than 1 year)

The ASIR control system from Muller Martini is a vision system directly connected to the machine control. This system is used for quality assurance on saddle stitchers and gathering machines. It monitors the composition of products and prevents incorrectly placed signatures from being processed further. It consists primarily of a number of ASIR cameras, which are installed in the feeder’s infeed area and are networked with an independent bus system.

The individual sensors operate either in bar code or image comparison mode. They change over “automatically”. The system looks for a bar code on the first signature that passes by. If one is present, the bar code value is saved as a reference value. If no bar code is found, the sensor automatically changes to image comparison mode and saves a section of the printed signature image as a reference image.

Faulty signatures can be caused by

  • Placement of an incorrect signature pile.
  • Incorrect placement of the correct signature pile.
  • Placement of the correct signature pile with individual faulty signatures.

Faulty signatures can be recognized with almost 100% accuracy in bar code mode. Give me your experience if you already have ASIR 3. If you do not have ASIR3, let me know if you need more information on this technology. Have a great day!

    Hi Luciano
    May I ask what company you work for? Most of the time it needs to be recalibrated when you get these red lights instead of the green ones or the lenses are dirty.
    No it cannot be used on a PC, only with the machines control system.
    Thanks.

    Hi Doug,

    I work for a company that bought a MM machine with the Asir system. The camera has started to blink the red led instead of the green one. Do you know why could it be happening? Is the solution only a new camera? The machine has less than 1 year and it is already happening to the third camera. Can I have an individual manual of this camera? Is it possible to install the camera on an normal desktop pc ou notebook and test it?

    Regards,

    Luciano Amaral.

    HI
    That sounds correct on your newer version ASIRCOM. Have you been in contact with a local MM service contact?

    In general the life time of an ASIR 3 system should be as long as it is supported by MM which in normal cases is approx. 10+ yrs.

    ASIR cameras should last 5+ years depending on consistent clean power to the system and general maintenance if performed.
    Hope that answers your questions.
    Regards,
    Doug

    Hi.
    Our machine use Asir 3 sensors, recently we install the new version ASIRCom-PC_V2_19, it can use Asir 3.1, Is it correct?, Wich is the lifetime of an Asir 3? these have worked for about 6 years in 2 shifts of 8 hours. Thank you.

    Best regards

  5. Hi,

    i am using asir v3.11 but the problem is that image recognition mode is working fine but in bar code mode its not recognizing the bar code can u pls give me specification of bar code like size and all

    thank u
    Regards,
