Printer Feeder Speed Control via External Temperature Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printers face issues with feeding speed control due to temperature discrepancies between the printer's internal temperature and the medium temperature, leading to either excessive feeding speed or motor step-out, caused by differences in environmental conditions or prolonged use.
Innovation Solution
A printer system that includes a feeder, printing head, communication device, and controller, which receives temperature data from other printers via wireless communication to adjust the feeding speed and printing head operation based on the received temperature data, ensuring appropriate control for the print-receiving medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the feeding means driving force is adjusted based on apparatus internal temperature, then the printing head temperature can be controlled, but the feeding speed becomes inaccurate when there is a significant difference between apparatus internal temperature and medium temperature
Solution Approach 1:
The patent introduces temperature data from other printers as an intermediary to estimate the medium temperature when the apparatus internal temperature significantly differs from the medium temperature. This mediator allows the system to infer the actual medium temperature condition without direct measurement, enabling accurate feeding speed control based on the estimated medium temperature rather than the potentially inaccurate apparatus internal temperature.
Solution Approach 2:
The system implements feedback by continuously monitoring the difference between apparatus internal temperature and medium temperature (estimated from other printers' data). When this difference exceeds a threshold, the system adjusts the feeding means driving force accordingly, creating a closed-loop control that adapts to temperature variations and maintains accurate feeding speed.
2Force
If the feeding means has a larger driving force when apparatus internal temperature is low, then feeding resistance is overcome, but excessively high feeding speed elongates printing contents
Solution Approach 1:
The patent dynamically changes the feeding speed parameter based on the estimated medium temperature. When medium temperature is high (indicating low feeding resistance), the system reduces feeding speed to prevent elongation of printing contents. When medium temperature is low (indicating high feeding resistance), the system increases feeding speed to ensure adequate feeding force. This parameter adjustment resolves the contradiction between overcoming feeding resistance and maintaining printing accuracy.
3Temperature
If the feeding means has a smaller driving force when apparatus internal temperature is high, then overheating is prevented, but step-out of stepping motor occurs when medium temperature is low
Solution Approach 1:
The system dynamically adjusts the feeding means driving force parameter based on the estimated medium temperature rather than relying solely on apparatus internal temperature. When medium temperature is low, the system maintains or increases driving force to prevent motor step-out, even if apparatus internal temperature is elevated. When medium temperature is high, the system reduces driving force to prevent overheating. This adaptive parameter change resolves the contradiction between temperature control and motor reliability.
Data Source
AI summary
The disclosure discloses a printer including a feeder, a printing, a communication device, and a controller. The controller is configured to execute a temperature reception process and a printing control process. In the temperature reception process, first temperature data is received. The first temperature data is broadcast-transmitted from at least one other printer and corresponds to a first temperature inside the other printer. In the printing control process, a feeder and a printing head are controlled on the basis of the first temperature data to form a print on a printing medium and thereby generate a printed matter.
