Plotter Control Method for Roll Paper Acclimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional processing apparatuses, such as cutting plotters, face challenges in maintaining processing accuracy due to the expansion and contraction of deformable processing media like paper, which leads to wasteful consumption and increased processing time, especially when multiple sheets need to be processed sequentially.
Innovation Solution
A control method and device that feed out multiple processing ranges in advance, allowing them to acclimate to the environment before processing, and then retract them upstream to prevent external influences, while ensuring accurate timing and minimizing paper length to avoid folding and wrinkles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the processing medium is fed out in advance to allow it to fit to the environment, then processing accuracy is improved, but processing time increases
Solution Approach 1:
The processing medium is fed out in advance before processing to allow it to acclimate to the environment, preventing expansion and contraction during processing. This preliminary action ensures dimensional stability and processing accuracy without requiring excessive standby time during the actual processing operation.
Solution Approach 2:
The system dynamically adjusts the feeding amount based on real-time detection of the processing medium's state. By detecting when the medium has sufficiently acclimated and adjusting the feed timing accordingly, the system optimizes the balance between allowing proper acclimation for accuracy and minimizing unnecessary delays in processing.
2Manufacturing precision
If a long length of processing medium is fed out in advance, then processing accuracy is improved, but the medium may be folded or wrinkled causing malfunction
Solution Approach 1:
Instead of feeding out an excessively long length of processing medium, the system feeds out only the necessary partial amount required for acclimation. This prevents the medium from being folded or wrinkled while still providing sufficient length for the medium to adapt to environmental conditions and ensure processing accuracy.
Solution Approach 2:
The feeding amount is dynamically determined based on the specific processing requirements and detected acclimation state. The system adjusts the feed length to be sufficient for accuracy but not excessive, preventing folding and wrinkling that would cause feeding malfunctions.
3Manufacturing precision
If the processing medium is fed out manually by the user, then processing accuracy is improved, but operation complexity increases and the medium becomes bulky
Solution Approach 1:
The system automatically performs the feeding operation without requiring manual user intervention. The processing medium is fed out automatically by the feeding means based on detected conditions, eliminating the need for users to manually handle bulky lengths of medium while still achieving the acclimation necessary for processing accuracy.
Solution Approach 2:
The system uses detection means to monitor the processing medium's state and provides feedback to the control means, which automatically adjusts the feeding amount and timing. This closed-loop control eliminates manual operation complexity while ensuring the medium is fed out at the appropriate time and amount for accurate processing.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enhances processing accuracy by allowing each sheet to acclimate before processing, reduces wasteful consumption, and minimizes processing time by enabling parallel acclimation and processing of multiple sheets, while preventing folds and wrinkles.
Implementation Method 1
a roll paper which is used in a cutting plotter or the like has a property that, when fed out and exposed to the outside air, the roll paper expands and contracts under the influence of its temperature and humidity

AI summary
The control circuit controls the plotter provided with the feeding means for feeding out a roll paper and the processing means for processing the roll paper which is fed out by the feeding means. The control circuit includes the feeding control section which controls the feeding means so that, before the processing means starts processing on one page of the roll paper, a plurality of pages including the one page is fed out in advance and then, the page having been fed out in advance is pulled back and retreated at a position on an upstream side with respect to a processing position of the processing means, and the processing control section which controls the processing means so that processing of the one page is started when an elapsed time of the one page having been fed out in advance has reached a predetermined stand-by time.
