Integrated Printing Device One-Pass Sheet Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-unit die-cutting stamping equipment cannot efficiently complete stamping, die-cutting, waste edges removal, and blanking processes in a single sheet-feeding operation, leading to inefficiencies and defects due to the need for manual labor and multiple device interactions, which result in deformation and reduced accuracy.
Innovation Solution
A single, integrated printing device with a sheet-conveying unit, stamping-control unit, die-cutting unit, waste edges removing unit, blanking unit, and waste removing unit, along with a gripper bar and gripper bar chain, allows for sequential processing of a single sheet to produce finished products, reducing the need for multiple sheet feedings and operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple separate devices are used for stamping, die-cutting, waste edges removal, and blanking, then each process can be performed with dedicated equipment, but the production efficiency is reduced and manual labor is required
Solution Approach 1:
The patent combines multiple separate processing devices (stamping device, die-cutting device, waste edges removing device, blanking device) into a single integrated printing device. This merging allows all operations to be performed in one continuous sheet-feeding process, eliminating the need for manual transfer between devices and improving production efficiency while reducing manual labor requirements
Solution Approach 2:
The integrated printing device is designed to perform multiple functions within a single machine system. The device can sequentially execute stamping, die-cutting, waste edges removal, and blanking operations on the same sheet material without requiring separate dedicated equipment for each process, thereby achieving multi-functionality and improving productivity
2Ease of manufacture
If manual labor is used to remove waste edges, then the process is simple, but the finished product may be torn and defect rate increases
Solution Approach 1:
The patent replaces manual mechanical removal of waste edges with an automated waste edges removing device that uses precision mechanical systems. This device can accurately identify and remove waste edges without manual intervention, eliminating the risk of tearing the finished product while maintaining ease of operation through automation
Solution Approach 2:
The integrated printing device performs waste edges removal automatically as part of the continuous processing sequence. The device self-regulates the removal process without requiring manual intervention, ensuring consistent quality and preventing damage to the finished product while maintaining operational simplicity
3Productivity
If multiple sheet-feeding processes are used to complete all operations, then each process can be optimized independently, but the overall processing time increases and production efficiency decreases
Solution Approach 1:
The patent implements a continuous sheet-feeding process where the sheet material moves continuously through all processing stages (stamping, die-cutting, waste edges removal, blanking) without interruption or re-feeding. This continuous action eliminates idle time between operations and significantly improves processing speed and production efficiency
Solution Approach 2:
The integrated device performs preliminary actions by pre-positioning and pre-coordinating all processing units along the sheet path before production begins. The device is configured to execute all operations in a predetermined sequence on a single sheet, eliminating the need for multiple sheet feedings and optimizing overall processing time

AI summary
The present invention relates to a printing device for producing finished product by one-pass sheet-feed comprising a sheet-conveying unit, stamping-control units, a die-cutting unit, a waste edges removing unit, a blanking unit, a waste removing unit, and a conveying mechanism. The operation method of the device may include transferring a single sheet to the stamping-control units by the sheet-conveying unit, gripping and transferring the sheet to the stamping-control units by a gripper bar, to stamp or indent; transferring the sheet to the die-cutting unit to complete the die-cutting work; transferring the sheet to the waste edges removing unit to remove part of the waste edges; transferring the sheet to the blanking unit to collect all finished product; and finally, transferring the last remaining waste edges to the waste removing unit.
