Embossing Device Integration in Printing Press Sheet Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing processing devices face challenges in performing emboss-processing without disrupting sheet feeding during the final process of printing, as the embossed portions on the sheets can get caught by other sheets when stacked, leading to poor sheet feeding.
Innovation Solution
A processing device is configured to perform emboss-processing as part of the final process of printing, after pattern printing and sheet transfer have been completed, ensuring that the embossed portions do not interfere with sheet feeding by integrating an embossing device and a final processing device that includes number printing and varnishing capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If emboss-processing is performed before final printing process, then the sheet can be processed for tactile feeling and security features, but the embossed portions cause poor sheet feeding when sheets are stacked
Solution Approach 1:
The patent applies preliminary action by performing emboss-processing at the final stage of the printing process, after all printing operations are completed. This timing ensures that embossed sheets do not interfere with subsequent sheet feeding operations, as the embossing is done just before the sheets are discharged and stacked for final collection.
Solution Approach 2:
The patent implements dynamics by making the processing sequence flexible and adaptive. The embossing device is integrated into the printing press and can be dynamically activated at the appropriate stage (after printing, before discharge). This dynamic timing resolution allows the system to adapt the processing sequence to avoid the sheet feeding problem while maintaining all required processing functions.
2Manufacturing precision
If emboss-processing is performed at an early stage, then the tactile feeling and security features are enhanced, but the embossed portions get caught by other sheets during stacking
Solution Approach 1:
The patent applies preliminary action by performing emboss-processing at the final stage of the printing process, after all printing operations are completed. This timing ensures that embossed sheets do not interfere with subsequent sheet feeding operations, as the embossing is done just before the sheets are discharged and stacked for final collection.
3Adaptability or versatility
If sheets are transferred to another processing machine for final printing, then the emboss-processing can be performed separately, but the embossed sheets experience poor sheet feeding in the final printing machine
Solution Approach 1:
The patent applies merging by integrating the embossing device directly into the printing press system. The embossing unit is combined with the printing cylinders and sheet transfer mechanisms, allowing emboss-processing to be performed as part of the same printing operation. This integration eliminates the need to transfer embossed sheets to another machine, thereby preventing sheet feeding problems.
Solution Approach 2:
The patent implements universality by designing a printing press that performs multiple functions: pattern printing, emboss-processing, and final printing operations all within a single integrated system. The printing cylinders and sheet transfer mechanisms serve dual purposes for both printing and embossing operations, eliminating the need for separate processing machines and associated sheet feeding issues.
