Bend-Breaking Cutter Wheel Direction Change for Glass Scoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass plate processing systems require a θ-axis servomotor and transmission members to change the rolling direction of the bend-breaking cutter wheel, leading to increased size, energy consumption, and processing time, which hinders efficiency and cost-effectiveness.
Innovation Solution
A bend-breaking device with a bend-breaking cutter wheel that is rotatable 360° around its center axis, combined with a scoring line forming mechanism and rolling direction changing means, allows for simultaneous direction change of the cutter wheel without a θ-axis servomotor or transmission member, enabling efficient scoring line formation and bend-breaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a θ-axis servomotor and transmission members are used to change the rolling direction of the bend-breaking cutter wheel, then the rolling direction can be changed, but the device size, energy consumption, and processing time increase
Solution Approach 1:
The patent removes the θ-axis servomotor and transmission members from the bend-breaking device, extracting the unnecessary components that caused increased device size and complexity. The cutter wheel is directly rotatable around its own axis without requiring additional drive mechanisms, thereby reducing the overall device footprint while maintaining directional control capability.
Solution Approach 2:
The bend-breaking cutter wheel is designed to be self-rotating around its own axis without requiring external θ-axis servomotor control. The cutter wheel inherently possesses the ability to change its rolling direction by simply rotating about its own center axis, eliminating the need for complex transmission systems and reducing energy consumption.
2Adaptability or versatility
If a θ-axis servomotor and transmission members are used to change the rolling direction of the bend-breaking cutter wheel, then the rolling direction can be changed, but energy consumption increases
Solution Approach 1:
The patent eliminates the θ-axis servomotor and its associated transmission members, removing the energy-consuming components from the system. The direct rotation of the cutter wheel around its own axis requires minimal energy compared to the original system with motors and transmissions, thereby reducing overall energy consumption while maintaining directional flexibility.
Solution Approach 2:
The cutter wheel performs self-rotation to change rolling direction without requiring external motorized control. This self-service mechanism significantly reduces energy consumption compared to the original system that relied on θ-axis servomotors and transmission members for direction changes.
3Adaptability or versatility
If a θ-axis servomotor and transmission members are used to change the rolling direction of the bend-breaking cutter wheel, then the rolling direction can be changed, but processing time increases
Solution Approach 1:
The patent removes the θ-axis servomotor and transmission members, eliminating the time-consuming components involved in direction changes. The cutter wheel can immediately change its rolling direction by rotating around its own axis without the delays associated with motor acceleration, transmission engagement, and position adjustment, thereby reducing processing time.
Solution Approach 2:
The self-rotating cutter wheel mechanism allows for instantaneous direction changes without the time required for θ-axis servomotor control and transmission operation. The cutter wheel directly responds to rotation commands, significantly reducing the processing time associated with changing rolling directions during bend-breaking operations.

AI summary
Provided is a bend-breaking device that changes a rolling direction of a bend-breaking cutter wheel in a peripheral area of a glass plate to a planned direction in which a scoring line to be formed next will extend simultaneously with formation of the scoring line in a bend-breaking processing. A first bend-breaking device and a second bend-breaking device move a bend-breaking jig from a scoring line forming start point 135a near an outer side of an outline cutting line K1 toward an outer peripheral edge 56c of a glass plate 11, form a scoring line K2 extending in a predetermined direction at a scoring line forming location of a peripheral area 56b of the glass plate 11, and move a bend-breaking cutter wheel to a rolling direction change point 135c near an inner side of the outer peripheral edge 56c of the glass plate 11. The bend-breaking jig is caused to travel in parallel with the upper surface 12 of the peripheral area 56b of the glass plate 11 in the planned direction in which the scoring line K2 to be formed next on the upper surface 12 to extend, and the bend-breaking cutter wheel that comes into contact with the upper surface 12 of the peripheral area 56b of the glass plate 11 and is rotatable by 360° in the direction around the cutter holder center axis is caused to rotate in the direction around the cutter holder center axis. While the rolling direction of the bend-breaking cutter wheel is changed to the planned direction in which the scoring line K2 to be formed next will extend, the scoring line K2 extending in the planned direction is formed in the vicinity of the inner side of the outer peripheral edge 56b of the glass plate 11.
