Label Applicator Arm With Dissolvable Liner For Continuous Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional label applicators experience inefficiencies due to a 'waiting time' requirement, where the next label cannot be printed until the tamp head returns to its original position after applying the preceding label, leading to downtime and reduced productivity in high-volume label printing and application processes.
Innovation Solution
The implementation of a label printing and applying system that uses a dissolvable liner on labels, allowing for continuous printing and application by activating the liner with a fluid, enabling the arm to collect and apply labels without waiting for the tamp head to return, thus eliminating the waiting time requirement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional tamp head label applicator is used, then labels can be applied to substrates, but the next label cannot be printed until the tamp head returns to its original position, causing waiting time and reduced productivity
Solution Approach 1:
The system divides the label application function into two separate modules: a continuous printer that produces labels on a moving web, and a separate applicator mechanism that picks and places individual labels. This segmentation allows the printer to operate continuously without waiting for the applicator, eliminating the waiting time bottleneck and enabling independent optimization of each module's speed.
Solution Approach 2:
Labels are printed in advance on a continuous web medium before being individually picked and applied. The printer prepares multiple labels continuously ahead of time, so when the applicator needs a label, it is already available on the web, eliminating the need to wait for the tamp head to return before printing the next label.
2Ease of operation
If the tamp head moves to apply labels, then labeling function is achieved, but the system must wait for the head to return before printing the next label, reducing efficiency
Solution Approach 1:
The printer operates continuously on a moving web, producing labels without interruption. Meanwhile, the applicator independently picks and places labels at its own rhythm. This continuity allows both functions to operate simultaneously without the stop-start cycle of traditional systems, maximizing the productivity of both components.
Solution Approach 2:
A continuous web medium acts as an intermediary carrier between the printer and the applicator. The web transports printed labels to the applicator, decoupling the printer's continuous operation from the applicator's intermittent picking and placing actions, thereby enabling high-speed continuous production.
3Reliability
If the system uses a traditional printing and application mechanism, then labels are applied correctly, but downtime increases due to the waiting time requirement
Solution Approach 1:
The system transitions from a static, sequential process to a dynamic, parallel process. The continuous web moves dynamically through the system, allowing the printer and applicator to operate in parallel with independent timing. This dynamic architecture eliminates the mandatory waiting period while maintaining precise label placement through synchronized picking and placing mechanisms.

AI summary
A method for printing and applying labels comprises printing indicia on a first label using a printer to form a first printed label and holding the first printed label in a holding tray. The method includes moving an arm from an original position to a first position to collect the first printed label from the holding tray, and rotating the arm in a first direction to move the first printed label towards a substrate. The method comprises moistening the first printed label to activate a dissolvable liner of the first printed label. The method includes using the arm to apply the moistened first printed label to the substrate. The arm is rotated in a second direction away from the substrate. The printer prints a second label before the arm returns to the original position to collect the second label from the holding tray.
