Coil Mapping

Automatic Feed Company’s coil mapping system allows coils with defect sections to pass through the blanking line without any negative impact on the quality of the stacks.

Possible defect position data is provided by the mill that manufactured the coil. Using this data, a line operator enters into HMI a series of ‘start and stop’ reject coordinates along the length of the coil.

At coil thread-up the leading edge of the coil is tracked through the machine and any cropped off material at the crop shear is accounted for. Next, the coil position is monitored during continuous production and when any of the predetermined “mapped” position are fed into the press the feed line will automatically reject the resulting parts within the defect starting and stopping positions. These rejected parts are not allowed to drop into the prime stacks and are directed into the reject tub at the end of the stacker. The rejects are counted as rejects and do not affect the stack counts.

This system, while requiring an end reject station, allows for inspection on the fly, which will enhance production.
