Gripper Bar Locking Apparatus for Sheet Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gripper bar locking apparatuses in sheet processing devices are difficult to adjust precisely due to the placement of components around the adjusting member, making it challenging for operators to ensure accurate positioning of gripper bars during the sheet processing.
Innovation Solution
A gripper bar locking apparatus with a supporting plate, lever portion, and cartridge that allows for easy adjustment of the gripper bar position, featuring a sliding mechanism and fastening means for precise locking and unlocking, with the cartridge and adjusting bolt positioned for easy access and improved rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adjusting member is installed at the periphery of the distal end of the supporting plate, then the locking function is achieved, but the adjustment becomes difficult to access and operate
Solution Approach 1:
The adjusting member is relocated from the periphery (distal end) to the proximal end of the supporting plate, changing its spatial position to a more accessible dimension. This allows operators to easily access and adjust the gripper bar position while maintaining the locking function through the connected lever portion mechanism.
Solution Approach 2:
The lever portion acts as an intermediary mechanism that transmits the adjustment motion from the adjusting member to the locking roller. By moving the adjusting member to an accessible location while maintaining mechanical connection through the lever portion, the system preserves the locking function while improving operational accessibility.
2Stability of the object's composition
If components such as protection cover, chain wheel, and connecting lever are disposed around the distal end of the supporting plate, then the structural integrity is maintained, but the adjusting member becomes difficult to access
Solution Approach 1:
The adjusting member is extracted from the crowded periphery area where it was obstructed by protection cover, chain wheel, and connecting lever. By relocating it to the proximal end of the supporting plate, the adjusting member is removed from the congested zone while the original components remain in place, preserving structural integrity while improving accessibility.
3Measurement precision
If the adjusting member is manually adjusted before each processing, then the precise positioning is achieved, but the operation time increases
Solution Approach 1:
The adjusting member is positioned at the proximal end of the supporting plate where it can be easily accessed and adjusted before processing begins. This preliminary positioning in an accessible location allows operators to quickly make necessary adjustments without time-consuming search or complex manipulation, reducing the time loss while maintaining positioning precision.
