Sealing Apparatus Cover Film Positioning Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sealing apparatuses require manual user intervention for initial positioning of the cover film, leading to low user friendliness, operability, and safety issues, with risks of contamination and wastage of the cover film.
Innovation Solution
A sealing apparatus equipped with sensors and a control unit to automatically detect and align the leading end of the cover film with the cutter position, using feed rollers to accurately position and cut the cover film, reducing manual intervention and preventing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual initial positioning is used, then the apparatus structure is simple, but operability and safety deteriorate due to user involvement and contamination risks
Solution Approach 1:
The apparatus performs initial positioning automatically without user intervention. The sensor detects the leading end of the cover film and the control unit controls the feed rollers to draw the cover film to the correct position, making the system self-servicing and eliminating manual positioning operations
Solution Approach 2:
The manual mechanical positioning operation is replaced by an automated system combining a sensor (optical or electromagnetic field) and a control unit that electronically controls the feed rollers, substituting human mechanical action with an automated electromechanical system
2Measurement precision
If manual visual checking is used for positioning, then the apparatus structure is simple, but positioning accuracy deteriorates and time is wasted
Solution Approach 1:
The sensor provides real-time feedback by detecting when the leading end of the cover film reaches a reference position. The control unit receives this feedback signal and automatically adjusts the feed rollers to achieve precise positioning, creating a closed-loop control system that ensures accuracy without manual visual checking
Solution Approach 2:
Manual visual inspection is replaced by an automated sensor system that electronically detects the position of the cover film leading end, substituting human sensory limitations with precise electromagnetic or optical detection capabilities
3Loss of substance
If excessive cover film is drawn during positioning, then positioning is simple, but material waste increases
Solution Approach 1:
The sensor continuously monitors the position of the cover film leading end and provides feedback to the control unit, which precisely controls the feed rollers to stop at the exact required position, eliminating excessive drawing and minimizing material waste through precision control
Solution Approach 2:
The system automatically determines and executes the precise amount of cover film to draw based on sensor detection and control unit calculation, eliminating the need for users to over-draw material as a safety margin and thereby reducing waste through intelligent self-regulation
4Reliability
If manual cutter operation is used, then the apparatus structure is simple, but safety deteriorates due to misoperation risks
Solution Approach 1:
The cutter operation is automated through the control unit, which activates the cutter automatically after confirming proper cover film positioning through sensor feedback, eliminating manual cutter operation and associated safety risks while maintaining simple mechanical cutting functionality
Solution Approach 2:
The sensor provides confirmation feedback that the cover film is correctly positioned before the control unit activates the cutter, creating a safety interlock system that prevents misoperation by ensuring proper conditions are met before cutting occurs

AI summary
This invention addresses the problem of providing a sealing apparatus that makes it possible to: enhance the operability, workability, and safety of initial cover film positioning compared to the prior art; prevent cover film and the apparatus interior from becoming unclean and having foreign matter adhere thereto; and accurately position such that cover film is not wasted. To solve this problem, a sealing apparatus (10) is made to comprise a sealing unit (42), feed rollers (54) that is provided between a mounting portion (30) that a cover film (26) is mounted on and a cutter (50) and is capable of moving the cover film (26) forward and backward, a first sensor (64) that is capable of detecting a leading end portion (26a) of the cover film (26) on the downstream side of the feed rollers (54), and a control unit (62), and the control unit (62) uses position information from the first sensor (64) to carry out control for cutting the cover film (26) after drawing the same out to a position at which the leading end portion (26a) is beyond the cutting position of the cutter (50) by a prescribed length.
