Fuji Seal International. has filed a patent for an apparatus that attaches shrinkable labels onto products on a conveyor. The apparatus uses two sets of light emitters arranged on both sides of the conveyor to create an irradiation volume. The light emitters emit directed light bundles in different directions, intersecting with the conveyor’s central axis. The patent claim emphasizes that the intersection points of the light bundles on the same side of the conveyor differ from each other.

A recently filed patent (Publication Number: US20230227197A1) describes an apparatus for attaching shrinkable labels onto products placed on a conveyor. The apparatus consists of two sets of light emitters arranged on both sides of the conveyor, emitting directed light bundles into an irradiation volume through which the conveyor passes. The directions of the light bundles intersect with the longitudinal central axis of the conveyor, but the intersection points differ from each other. The two sets of light emitters are symmetrically arranged with respect to the conveyor. The irradiation volume has an oval or elliptical shape in a plan view of the apparatus.
The apparatus also includes side reflectors that form side boundaries of the irradiation volume, reflecting light emitted by the light emitters into the irradiation volume. Additionally, there may be top and bottom reflectors that constitute the top and bottom boundaries of the irradiation volume. The reflectors are flat and made of aluminum sheet metal or aluminum foil.
The apparatus is controlled by a controller to emit light bundles and irradiate the shrinkable label on the product in the irradiation volume. The light emitters can be UV light emitters, such as LEDs, mercury lamps, halogen lamps, or IR lamps.
The patent also describes methods of attaching shrinkable labels to products using the apparatus. The product is transported on the conveyor through the irradiation volume, and the light emitters are controlled to continuously or discontinuously emit light bundles during transportation. The relative power output of the light emitters can be adjusted, with one method specifying a relative power of 65% and another method specifying a relative power of 60% to 100%.
Overall, this patent presents an apparatus and methods for efficiently attaching shrinkable labels onto products using directed light bundles emitted from two sets of light emitters. The apparatus includes reflectors to optimize the reflection of light into the irradiation volume. The methods provide flexibility in controlling the emission of light bundles and adjusting the power output of the light emitters.
