Vacuum Pick-Up for Adhesive Roll Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive rolls in contact cleaning systems lose effectiveness over time as debris covers the adhesive surface, necessitating removal, which current methods complicate and contaminate additional surfaces, increasing costs and complexity.
Innovation Solution
A contact cleaning system with an adhesive sheet removal device using a pick-up element that applies vacuum and sheer force to lift the leading edge of the adhesive sheet, transferring it to a waste roller with heating and pressure elements to secure it, and an indicator system for automated detection and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a further adhesive surface is used to lift the spent adhesive sheet, then the adhesive sheet can be removed from the adhesive roll, but the further adhesive surface becomes contaminated and requires renewing or replacing, adding complexity and expense
Solution Approach 1:
A non-adhesive pick-up element acts as an intermediary between the spent adhesive sheet and the adhesive roll. This element lifts the spent sheet without requiring adhesive contact, thereby avoiding contamination while enabling effective removal. The pick-up element serves as a mediator that transfers the spent sheet to a waste collection area without compromising system cleanliness.
Solution Approach 2:
The patent replaces the adhesive-based mechanical system with a vacuum-based mechanical system. Instead of using adhesive forces to lift the spent sheet, a vacuum pick-up element uses pressure differential to grasp and lift the sheet. This substitution eliminates the need for further adhesive surfaces, reducing system complexity and avoiding contamination issues.
2Ease of operation
If an adhesive surface is used to lift the adhesive sheet, then the sheet can be removed, but the adhesive surface may not be strong enough or may lift more than one sheet
Solution Approach 1:
The patent replaces adhesive-based removal with vacuum-based removal. The vacuum pick-up element uses controlled pressure differential to lift exactly one spent adhesive sheet at a time. This mechanical approach provides more reliable and controllable removal compared to adhesive surfaces, which vary in strength and may inadvertently lift multiple sheets.
Solution Approach 2:
The patent changes the operating parameter from adhesive strength to vacuum pressure. By controlling the vacuum pressure level, the system can reliably lift spent sheets without affecting fresh adhesive surfaces. The parameter control enables precise selection of which sheet to lift, improving reliability and preventing accidental removal of multiple sheets.
3Device complexity
If manual removal of adhesive sheets is used, then the system remains simple, but downtime increases and operating efficiency decreases
Solution Approach 1:
The patent implements self-service adhesive sheet removal where the system automatically detects and removes spent sheets without manual intervention. The vacuum pick-up element autonomously identifies and lifts spent adhesive sheets, transferring them to waste collection areas. This automation maintains relative system simplicity while dramatically improving operating efficiency and eliminating downtime associated with manual removal.
