Bottom Tape Applicator Large Roll Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bottom tape applicators are limited to smaller diameter tape rolls, restricting the use of larger rolls and increasing production downtime, as existing solutions like the Lam patent only facilitate rapid roll changes for top sealing and not for bottom sealing.
Innovation Solution
A bottom tape applicator system with a stationary frame, pivotable base unit, and detachable unit that allows for easy insertion and removal of large diameter tape rolls, featuring a slide-in mounting mechanism and cooperating couplers to connect the rear wipe down with the front applicator, enabling efficient application and replacement of large rolls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional bottom tape applicators are used with small diameter tape rolls, then the machine structure remains compact, but production downtime increases due to frequent roll replacements
Solution Approach 1:
The bottom tape applicator is divided into a stationary frame and a movable applicator assembly that can be detached and repositioned. This segmentation allows the tape roll mounting area to be accessed from below the conveyor, enabling the use of larger diameter rolls without increasing the overall machine footprint.
Solution Approach 2:
The tape roll mounting mechanism is repositioned to operate in a different spatial dimension - specifically, the roll is mounted below the conveyor rather than above or at the side. This dimensional change allows larger rolls to be accommodated within the same horizontal envelope by utilizing the vertical space beneath the conveyor.
2Productivity
If larger diameter tape rolls are used to reduce replacement frequency, then production downtime decreases, but the machine structure becomes too complex to accommodate the larger rolls in bottom sealing position
Solution Approach 1:
The applicator assembly is designed with movable and detachable components that allow dynamic reconfiguration. The assembly can be easily removed and repositioned to accommodate different roll sizes, and the coupling mechanisms allow for quick adjustment without requiring complex structural modifications to the main machine frame.
3Ease of operation
If the Lam patent solution is used for top sealing with large rolls, then rapid roll replacement is achieved, but the solution cannot be applied to bottom sealing
Solution Approach 1:
The bottom tape applicator is designed with universal features that enable it to function similarly to the top sealing applicator in the Lam patent. The detachable applicator assembly with standardized coupling mechanisms allows for rapid roll replacement comparable to top sealing applications, while specifically adapting the mounting geometry to work below the conveyor for bottom sealing operations.

AI summary
A bottom tape applicator that facilitates changing of large diameter tape rolls is provided that is composed of a stationary frame mounted in the machine and through which a full roll of tape may be passed and that mounts a detachable unit that is replaced to replace the tape roll and a base unit movable between an open position and an operative position. The base unit combines with the detachable unit mounted in operative position in the stationary frame to form an operative tape applicator.
