Gripper Transporter Aligns Paper Tips to Prevent Stagnation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medium processing devices face challenges in aligning and transporting media due to issues like stagnation in transport paths and inadequate alignment, particularly when the circumferential speed of paddles is not optimal, leading to buckling or failure to reach contact portions.
Innovation Solution
A medium processing device equipped with a gripper that moves along the transport path to grip and align the medium's tip, ensuring reliable transport to a contact portion for stacking, thereby alleviating stagnation and alignment issues by gripping the medium before it passes through the supply portion and moving it to the contact portion without interference with the stacker.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a paddle with a wing is used to align the medium by rotation, then the medium can be moved to the contact portion, but the medium may stagnate in the transport path before reaching the paddle
Solution Approach 1:
A guide member is introduced as an intermediary component between the supply portion and the paddle. This guide member has a guide surface that guides the medium to the contact portion, ensuring reliable transport before the paddle performs alignment. The guide member acts as a mediator that prevents stagnation while maintaining the paddle's alignment function.
2Ease of operation
If the paddle is positioned in the upper portion of the tray, then the medium can be aligned, but the medium may bend when the circumferential speed of the wing is lower than the feeding speed
Solution Approach 1:
The guide member performs preliminary action by guiding the medium to the contact portion before the paddle acts on it. This preliminary guidance ensures the medium is properly positioned and supported, preventing bending that would occur if the paddle alone tried to align the medium at higher speeds.
3Productivity
If the circumferential speed of the wing is too high, then the medium is transported quickly, but the lower end of the medium bounces back when contacting the contact portion, preventing alignment
Solution Approach 1:
The guide member performs preliminary guidance of the medium to the contact portion, ensuring proper positioning before the paddle's high-speed action. This preliminary action allows the system to use higher circumferential speeds for improved productivity while preventing the bouncing back issue through proper guidance.
4Device complexity
If the medium is fed by inertial force and gravity alone, then the structure is simple, but the medium may buckle and fail to reach the contact portion
Solution Approach 1:
The guide member serves as an intermediary that provides minimal additional structure to ensure reliable medium transport. It guides the medium along a defined path to the contact portion, preventing buckling without requiring complex mechanisms, thus maintaining relative simplicity while improving reliability.

Function Achieved in This Case
The solution ensures reliable alignment and stacking of media by gripping the medium's tip and moving it to the contact portion, preventing stagnation and maintaining alignment even when the stacking space dwindles, effectively performing processes like saddle stitching and folding.
Implementation Method 1
