Multivac Vision System MVS seal seam scanner

The Multivac Vision System MVS seal seam scanner from Multivac Marking & Inspection is an inspection system which checks the quality of seal seams during the packaging procedure. The system scans the seal seams while they are still in the thermoforming packaging machine and faulty packs can be detected before they are dispatched.

The inspection is fully automatic and captures 100% of all packs without any contact, making the system wear free. The scanner detects foreign bodies in the seal seam from a size as small as 0.5 mm², as well as detecting incomplete seal seams or faults such as creases or bubbles. The system is suitable for all film materials; at least one of the two films must be transparent.

The scanning range is up 700 mm width. The rapid image processing of the scanner ensures that there is a high level of throughput. The line scan camera is integrated in the thermoforming packaging machine as is the lighting, and the brightness can be adjusted. A further advantage is its small space requirement, the thermoforming packaging machine is only 60 cm in length.

No additional transport conveyor system is required for the operation within the packaging machine of the seal seam scanner. It can be easily retrofitted to existing machines and is maintenance free.The system also supports the traceability of packs, since it has an image archive of faulty products complete with time signature as well as a machine logbook.
