Media Processing Device Upstream Conveyance for Compact Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media processing devices face challenges in reducing size due to the requirement for long conveyance paths to accommodate next processes based on the results of initial processes, limiting compact device design.
Innovation Solution
A media processing device with a conveyance unit, a first process unit, a second process unit downstream, and a process control unit that determines and executes subsequent operations based on the first process's results, allowing for upstream conveyance of the medium if necessary, enabling compact design by alleviating constraints on conveyance path length and process unit positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the conveyance path is made long to accommodate next process positioning, then the process medium can be processed according to results, but the device size increases
Solution Approach 1:
The conveyance unit dynamically adjusts the conveyance direction based on process results. After the first process unit completes processing, the conveyance unit can reverse the medium's movement direction to convey it back upstream to the second process unit, enabling adaptive process sequencing without requiring extended conveyance paths.
Solution Approach 2:
The invention allows the process medium to be conveyed in reverse direction (upstream) after reaching the downstream position. The conveyance unit can reverse the normal conveyance direction to return the medium to earlier positions, enabling flexible process arrangement without increasing device footprint.
2Productivity
If the second process unit is positioned downstream, then processing sequence is maintained, but conveyance path length increases
Solution Approach 1:
The conveyance unit dynamically controls the medium's position and movement direction. After the first process unit finishes, the conveyance unit can stop the medium at any position along the path and reverse direction to convey it to the second process unit, maintaining efficient processing sequences without requiring the second unit to be far downstream.
Solution Approach 2:
The system prepares the process medium by conveying it to appropriate positions before each process unit operates. The conveyance unit can pre-position the medium upstream of the second process unit before the first process completes, ensuring the medium is ready for the next process without requiring long conveyance paths.
Data Source
AI summary
A compact media processing device enables recording on a process medium and then processing the process medium based on the result of recording. The media processing device conveys a process medium and processes the conveyed process medium by a first process unit disposed to the conveyance path, and an operation selection unit then determines the content of the next operation based on the result of the first process. After the next operation is determined, the conveyance control unit conveys the process medium upstream to or upstream of the process position of a second process unit. A process control unit then applies the selected operation to the process medium by the second process unit that is disposed downstream from the first process unit on the conveyance path of the process medium.
