ABSTRACT:
Apparatus for packaging articles in clear clamshell packages includes a pair of parallel relatively narrow, laterally spaced apart conveyor belts that support there-between a package in open position by its opposing side peripheries. A stack of packages is supported in nested configuration adjacent the front end of the conveyor and de-nester mechanism withdraws packages there-from and places them on the conveyor.As the package is advanced a robotic arm picks and places articles of commerce and associated product information card in the package cavity. A rotating roller coated with UV-responsive adhesive coats raised male surfaces of the advancing package. Next an air knife sends a jet of air upwardly to cause the open package lid to rotate upwardly to cover the article-receiving portion. A driven roller presses the lid downwardly to fully close it and cause the adhesive coated surfaces to fully engage the corresponding grooves on the article-receiving portion. The package is then delivered to a UV illumination chamber where the UV adhesive in instantly cured to seal the package.
