Transport Device Coupling Portion for Base Material Joining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing machines face challenges during the replacement of new base materials, where the magnetic fixing mechanism can lead to increased working time due to potential slippage or user error, resulting in incomplete joining of base materials and subsequent misalignment during transportation.
Innovation Solution
A transport device with a coupling portion that includes a support portion and temporary fixing portions for both the feeding and winding sides, ensuring that the boundary between the two media is exposed upward, facilitating reliable temporary fixing and efficient joining using a tape or crimping mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If magnets are used to temporarily fix base materials to the cutting table, then the base materials can be held in place during replacement operations, but the magnets may slip out due to weak magnetic force or user error, causing the base material to fall out of the transport path
Solution Approach 1:
The patent replaces the magnetic fixing system with a mechanical pressing system. The pressing portion applies direct mechanical pressure to the base material through the cutting table, eliminating reliance on magnetic force that can slip or fail. This mechanical approach provides more reliable and controllable fixing during base material replacement operations.
2Ease of manufacture
If the user manually joins base materials with tape, then the joining process can be performed, but the joint may be insufficient and base materials may separate during transportation, increasing working time
Solution Approach 1:
The pressing portion automatically performs the joining function by applying pressure to secure the base materials together during replacement. This eliminates the need for manual tape application by the user, providing consistent and reliable joining through automated mechanical pressure that ensures base materials remain securely connected during transportation.
3Ease of manufacture
If the boundary between base materials is not exposed, then the joining process may be more complex, but exposing the boundary upward requires additional space and may complicate the device structure
Solution Approach 1:
The cutting table surface serves multiple functions: it provides the pressing surface for the pressing portion, supports the base materials during replacement, and exposes the boundary upward for joining operations. This multi-functional design achieves the joining capability without adding separate complex structures, as the cutting table itself facilitates both pressing and boundary exposure.

AI summary
A transport device includes a feeding portion feeding a printing medium, a winding portion winding the printing medium fed from the feeding portion, and a coupling portion coupling the printing medium on a feeding side extending from the feeding portion and the printing medium on a winding side extending from the feeding portion between the feeding portion and the winding portion, wherein the coupling portion includes a cutting table supporting the printing medium, a first fixing roll temporarily fixing the printing medium on the feeding side to the cutting table, and a second fixing roll temporarily fixing the printing medium on the winding side to the cutting table, and the first fixing roll and the second fixing roll temporarily fix each printing medium in a state in which a boundary between the printing medium on the feeding side and the printing medium on the winding side is exposed upward.
