Recording Apparatus Synchronizes Ink Discharge and Conveyance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording systems require manual adjustment of post-processing start timing with respect to image formation start timing, leading to positional displacement and inefficiencies, especially during image formation restarts after temporary stops.
Innovation Solution
A recording system with a control unit that synchronizes the conveyance and ink discharge of the recording target medium to ensure the restart position aligns with an integer multiple of the image pitch, allowing automatic adjustment of post-processing timing and position relative to the image formation timing, thereby reducing positional displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of post-processing start timing is performed, then ease of operation is reduced, but manufacturing precision can be maintained through user control
Solution Approach 1:
The system automatically detects the image formation start timing and calculates the post-processing start timing based on the conveyance speed and pitch, eliminating the need for manual user adjustment. The control unit self-regulates the timing synchronization between recording and post-processing operations.
Solution Approach 2:
The control unit continuously monitors the conveyance speed of the recording target medium and adjusts the post-processing start timing based on feedback from the actual conveyance conditions, ensuring accurate timing synchronization without manual intervention.
2Productivity
If conveyance speed is increased for main production, then productivity is improved, but manufacturing precision of post-processing timing may deteriorate
Solution Approach 1:
The control unit dynamically calculates the post-processing start timing based on the actual conveyance speed, which may vary during operation. This allows the system to maintain timing accuracy even when conveyance speed changes during high-speed production.
Solution Approach 2:
The system adjusts the post-processing start timing parameter based on the conveyance speed parameter, allowing timing accuracy to be maintained across different production speeds from low-speed adjustment to high-speed production.
3Adaptability or versatility
If image formation is temporarily stopped and restarted, then adaptability is improved, but manufacturing precision of post-processing position deteriorates due to timing shift
Solution Approach 1:
The control unit calculates and sets the post-processing start timing in advance based on the conveyance speed and pitch, ensuring that even after temporary stops and restarts, the timing relationship between image formation and post-processing is maintained accurately.
Solution Approach 2:
The system replaces manual timing adjustment with automatic electronic control that calculates timing based on conveyance parameters, eliminating mechanical timing drift that occurs during stop-and-restart operations.

AI summary
A recording system that when formation of the image is restarted after a temporal stop of the formation of the image by temporarily stopping the conveyance of the recording target medium by the first conveyance unit and the discharging of the ink from the discharging part, a distance from a first position to a recording restart position is an integer multiple of image formation pitch, the first position being based on a position, at the time of the temporal stop, of the image that is formed on the recording target medium before the temporal stop, the recording restart position being a position where the ink is discharged at the time of the restart; and performing the post-processing on the recording target medium at the post-processing unit each time the recording target medium is conveyed, by the second conveyance unit, a distance corresponding to the image formation pitch.
