Vorrichtung und Verfahren zum Anbringen von Etiketten an kleinen zylindrischen Gegenständen mit einer gesten Rakelvorrichtung.

摘要

An apparatus (10) for applying thin film polymer labels onto small cylindrical articles has a label transport drum (20) with a substantially smooth, outer surface on which labels are fed. A cold adhesive that is viscous at room temperature is printed onto an area adjacent the leading edge of the label. A solvent is applied by two static wiper assemblies (172a, 172b) onto an area adjacent the trailing edge of the label. The first static wiper assembly (172a) wipes an amount of solvent onto the area adjacent the trailing edge of the label for cleaning and softening that area. A second wiper assembly (172b) applies an amount of solvent onto the area adjacent the trailing edge of the label for dissolving a portion of the label to create a tacky, bonding quality to the label and form a solvent seal bond when the trailing edge overlaps the leading edge. Solvent is applied to the wiper bodies (172a) for dispersion throughout and to the wiper tip. A plunger (132) is formed in the drum at those areas where the trailing edges of labels are positioned. Each plunger (132) is spring biased outward from the drum surface to position the trailing edge of a label at a position beyond the peripheral drum surface for engaging the wiper tips. During wrapping, the article forces the plunger downward so it will not interfere with article wrapping.
