Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional linear or vertical binding machinery is used, then the binding process can be performed, but the machine structure becomes lengthy and complex, reducing ease of operation and increasing device complexity
Solution Approach 1:
The patent transitions from conventional linear or vertical binding machinery to a rotary horizontal configuration. The indexing table rotates horizontally to transport paper bunches between stations, changing the spatial dimension of operation from linear/vertical to rotary horizontal. This dimensional change compactes the machine structure while maintaining all necessary binding functions, directly resolving the contradiction between ease of operation and device complexity
2Productivity
If manual formation of angle and curvature is performed, then the coil can be positioned for binding, but the process requires skilled operators and takes time, reducing productivity
Solution Approach 1:
The patent incorporates automatic angle and curvature formation mechanisms that prepare the paper bunches in advance before they reach the binding station. The indexing table system pre-positions and pre-forms the paper bunches with correct angles and curvatures, eliminating the need for manual formation by skilled operators during the binding process. This preliminary automation directly increases productivity while reducing operational complexity
3Ease of repair
If conventional binding machinery is used, then the binding process can be completed, but maintenance and parameter setting are difficult, increasing device complexity
Solution Approach 1:
The patent segments the binding machine into modular stations mounted on the rotary indexing table, including separate stations for angle formation, curvature formation, coil insertion, and binding. Each station can be independently accessed, adjusted, and maintained. This modular segmentation allows operators to easily access and adjust parameters at each station without disassembling the entire machine, directly improving ease of repair while maintaining manageable device complexity

AI summary
The present invention relates to Indexer table (1) for rotary and horizontal shifting of paper bunches. Said indexer table (1) having spider arms shifted in rotary manner through pinion gear and servo motor. The drive power is provided to auxiliary shaft (5) from main shaft (4) through the pulley (11) and belt (19d) configuration. The juxtaposed shafts receive the drive power from the auxiliary shaft (5) through universal joints (10). The cam (12) on each shaft rotates along with rotation of the shaft for reciprocal movement of spider arm (20). The actuator (13) actuates follower (13b) for open and close movement of bunch gripper (21). Said bunch gripper (21) grips bunch paper and then said driven shaft (14) rotates so that the spider arm (20) shifts bunch paper in rotary manner. After performing operation of bunch paper, the spider arm (20) shifts bunch paper to next platform.
