Stencil Printing Machine Removable Plate Ejecting Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stencil printing machines face difficulties in maintaining confidentiality of used masters during jam repairs, as bolting the printing machine's door complicates the process and may compromise confidentiality, while existing solutions that alter the master's state increase machine size, parts, and cost.
Innovation Solution
A stencil printing machine design featuring a plate ejecting device with a removable and boltable lid body, allowing for external removal of the plate ejecting device while maintaining confidentiality, eliminating the need to bolt the machine's door during repairs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the door of the printing machine is bolted to maintain confidentiality, then the used master cannot be freely taken out, but it becomes necessary to unbolt the door every time a jam occurs, complicating the repair process and preventing confidentiality functions during fixing
Solution Approach 1:
The plate ejecting device is segmented from the main printing machine body, allowing it to be independently removed. This segmentation enables the door to remain bolted for confidentiality while the plate ejecting device can be accessed separately for jam repairs, resolving the contradiction between maintaining security and enabling easy maintenance.
Solution Approach 2:
The plate ejecting device is extracted as a separate removable component from the printing machine. This extraction allows maintenance personnel to remove only the plate ejecting device for jam repairs without needing to unbolt the main door, thus maintaining confidentiality while enabling easy repair access.
2Reliability
If heating or physical damaging processes are applied to the used master to maintain confidentiality, then the master gets into an unreusable state, but it requires newly providing devices for these processes, increasing size, number of parts, and cost
Solution Approach 1:
The bolting mechanism on the plate ejecting device provides self-service confidentiality protection. The simple mechanical bolting system secures the used master without requiring complex heating devices, physical damaging mechanisms, or other elaborate security systems, thus maintaining confidentiality while avoiding increases in machine size and parts.
3Reliability
If the door is bolted to prevent master removal, then confidentiality is maintained, but fixing jams becomes very complicated as the door must be unbolted every time
Solution Approach 1:
The plate ejecting device is segmented as a separate removable module, allowing jam repairs to be performed on this specific component without affecting the main door security. This segmentation enables easy repair access while maintaining overall confidentiality through the bolted door.
Solution Approach 2:
The plate ejecting device is extracted as an independent removable unit. This extraction allows maintenance personnel to remove and service the plate ejecting device for jam repairs without needing to access the interior through the main door, thus maintaining confidentiality while enabling straightforward repairs.

AI summary
In a stencil printing machine including a plate discharge device for stripping a master from a plate cylinder and collecting the master after attaching the master subjected to plate making to the plate cylinder for printing on a sheet, the plate discharge device includes a storing section for storing the master, a lid for closing the storing section to be opened/closed freely, and a device for locking the lid in a closed state, the plate discharge device being provided such that it can be taken out to the housing of the stencil printing machine. Consequently, a stencil printing machine from which the plate discharge device can be taken out while secrecy is kept surely can be provided.
