The
Pick Light system is capable of automatically indicating
the specific parts that are required for an assembly unit.
The system alerts the operator as to the proper part or
parts that need to be picked and can verify that the operator
has picked the correct parts.
The Pick Light system annunciates
to the operator the required part(s). This is performed
by turning on a pilot light(s) that coincides with the
location of the material stored in the rack. One or more
part locations can be illuminated. A light screen matrix
is mounted around the storage rack, ultimately determining
the point at which an operator's hand has entered into
the storage rack. This matrix is accurate to a closer
tolerance than the width of a small child's hand. A dead
buffer zone is also added to prevent crossover trips to
adjacent bins of storage areas.
The overall scheme, of this
device, is to have a part location light up when a unit
is detected as it passes by the system. A buzzer will
sound in the event the operator picks a part that is not
illuminated; the buzzer will silence when the operator
removes their hand. When an operator picks from an illuminated
bin, the buzzer remains silent and the light will go out
once the operator removes their hand from the light matrix
