Abstract:
An apparatus and method for automatically modulating vacuum applied to a vacuum cup are described herein. More particularly an automated labeling apparatus and method for applying labels onto containers using a vacuum based transport mechanism is described herein.
Abstract:
A reusable, liner-free labeling system, which allows labels to be wound without the use of a release liner, is described herein. The absence of a liner reduces inventory requirements, roll-changeover time, cost of production, and waste. Additionally, the labeling system described herein provides labels that remove cleanly, which reduces the time required to remove the label and eliminates the necessity of cleaning the substrate after removal. The labeling system provides labels that can be easily reused and reapplied, which can reduce time and costs associated with user labeling error. The labeling system is compatible with labels of all currently available facesheets, regardless of composition or physical characteristics, and allows for large quantity batch printing. The implementation of the labeling system does not require any changes to the pre-existing label printing infrastructure.
Abstract:
An apparatus and method is described herein for automatically labeling using labels having a fluid activatable adhesive along the back surface of such label. The apparatus has multiple pallets each being positionable with the lowermost label of a stack of one or more labels to releasably secure by suction the label against the pallet, and multiple pads each being positionable with respect to pallets to receive labels from the pallets and then releasably retain such labels until application onto containers. Fluid for activating adhesive is applied by an applicator onto labels retained upon the pad to change the fluid activatable adhesive along the label's back surface from a non-tacky state to a tacky state just prior to application of the label onto container.
