Laser Edible-Body Marking for Random Tablet Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing edible-body marking devices face challenges in efficiently forming marking patterns on edible bodies with random orientations, leading to longer processing times and reduced marking quality when the orientation is reversed, as the moving distance and scanning speed need to be adjusted.
Innovation Solution
An edible-body marking device that includes a carrier, detection, and laser processing parts, where the detection part acquires orientation information and the laser processing part uses pre-stored marking procedure information to adjust the start points and form the marking pattern based on the orientation, allowing for swift and precise marking regardless of the edible body's orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the moving speed of the tablet is increased to reduce marking formation time, then productivity is improved, but the scanning speed of laser light must be increased accordingly causing marking quality to decline
Solution Approach 1:
The marking start point is dynamically adjusted based on the detected orientation of the tablet. The system detects the tablet's orientation and selects different start points from multiple pre-stored marking procedure information sets, allowing the marking process to adapt to varying tablet orientations and maintain optimal marking quality across different production speeds
Solution Approach 2:
The system changes the parameter of marking start point position based on tablet orientation. Multiple marking procedure information sets are stored with different start points, and the appropriate set is selected according to the detected orientation, enabling the system to optimize both speed and quality for different operational conditions
2Adaptability or versatility
If the tablet moves in the opposite direction due to vertical reversal of orientation, then the marking can still be formed, but the moving distance increases causing formation time to extend
Solution Approach 1:
Multiple marking procedure information sets with different start points are pre-stored in the system. When a tablet's orientation is detected, the system quickly retrieves the appropriate pre-prepared marking procedure, eliminating the need for real-time calculation and enabling immediate adaptation to any orientation
Solution Approach 2:
The system dynamically selects the optimal marking start point based on the detected tablet orientation. By having multiple pre-configured start points and selecting the appropriate one based on orientation detection, the system adapts to random orientations while maintaining efficient marking formation time

AI summary
An edible-body marking device (1) has a carrier device (20) that carries an edible body, a detection part (210) that detects the edible body, and a laser processing part (220) that forms a marking pattern on the edible body by using laser light. The carrier device sequentially carries the edible body to the detection part (210) and the laser processing part (220). The detection part images (210) the edible body to acquire orientation information regarding an orientation of the edible body, and the laser processing part (220) has a memory part that stores in advance multiple pieces of marking procedure information regarding formation procedures of the marking pattern in association with their respectively different pieces of the orientation information, and forms the marking pattern on the edible body according to the marking procedure information extracted from the memory part based on the orientation information acquired by the detection part (210).
