Printing Control Device Scheduling Reprints for Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inefficient re-printing processes due to the need for sheet exchange and device adjustment, which can lead to missed delivery dates when re-printing is not continuous with the original process, causing worker burden and timing issues.
Innovation Solution
A control device that predicts processing times and determines whether re-printing can be continuous with other processes using the same sheet, ensuring timely completion within the delivery date by managing the start and end times of printing, post-processing, and inspection tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If printing manufacture to be performed again is incorporated so as to be continuous with other printing manufacture using the same sheet, then worker burden is reduced and process efficiency is improved, but there is a possibility that the delivery date cannot be met
Solution Approach 1:
The system dynamically determines whether to incorporate reprinting manufacture into continuous processing based on real-time calculation of end times and delivery date comparisons. The control device adjusts the processing schedule flexibly by evaluating whether continuous processing will meet delivery requirements, allowing the system to switch between continuous and separate processing modes as needed.
Solution Approach 2:
The control device performs preliminary calculation of end times for reprinting manufacture before making the incorporation decision. By predicting the completion time in advance and comparing it with the delivery date, the system can proactively determine whether continuous processing is feasible, preventing delivery date violations before they occur.
2Reliability
If printing manufacture to be performed again is generated separately with sheet exchange and device adjustment, then delivery date can be ensured, but worker burden increases and efficiency decreases
Solution Approach 1:
The control device automatically determines whether reprinting manufacture should be incorporated into continuous processing by calculating end times and comparing with delivery dates. This self-service approach eliminates the need for workers to manually decide whether to perform sheet exchange and device adjustment, reducing operational burden while ensuring delivery date compliance through automated decision-making.
3Ease of manufacture
If reprinting manufacture is continuously processed with other printing manufacture, then sheet exchange and device adjustment are eliminated, but the end time may exceed the delivery date
Solution Approach 1:
The control device uses feedback from delivery date information and calculated end times to determine whether continuous processing should be implemented. By continuously monitoring whether the projected end time meets the delivery date requirement, the system adjusts its processing strategy, incorporating continuous processing only when it doesn't compromise delivery timelines.

AI summary
A control device includes a processor that controls a printing manufacturing process including printing processing and post-processing in plural types of printing manufacture, in which the processor is configured to: according to an occurrence of an event in which the printing processing has ended but printing manufacture to be performed again is required, acquire information about a type of a sheet from printing manufacture information about printing manufacture having a delivery date; predict a time required for each processing of the printing manufacturing process in the printing manufacture; calculate an end time of reprinting manufacture, in which the printing manufacture to be performed again is required, in a case where the reprinting manufacture is incorporated so as to be continuous with other printing manufacture in which the same sheet as the reprinting manufacture is used; and perform control to determine whether or not to incorporate the reprinting manufacture so that the reprinting manufacture is continuous with the other printing manufacture depending on whether or not the end time is in time for the delivery date.
