Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current manual sorting and picking processes in distribution centers are inefficient and labor-intensive, especially in large warehouses, where robots face challenges in accurately recognizing and stabilizing corrugated boxes and commodity packages, leading to difficulties in automation.
Innovation Solution
A picking apparatus with a carriage, holding mechanism, and movement mechanism, featuring a rotating arm with suction pads and a recognition device, allows for precise object recognition and stable picking by moving along multiple axes and using conveyor systems to facilitate efficient object transfer and verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual sorting and picking processes are used, then flexibility and adaptability to various objects are maintained, but productivity is low and labor intensity is high
Solution Approach 1:
The picking apparatus uses a recognition device to automatically identify objects and their positions, and the holding mechanism automatically adjusts to grasp them, eliminating the need for manual inspection and decision-making while maintaining adaptability to different objects
Solution Approach 2:
The patent replaces manual mechanical operations with an automated system comprising recognition devices (optical/electronic), control units (information processing), and holding mechanisms (robotic grippers), substituting human labor with an integrated automated picking system
2Productivity
If robots are used for automated picking, then productivity increases, but the ability to accurately recognize and stabilize corrugated boxes and commodity packages deteriorates
Solution Approach 1:
The patent introduces a recognition device as an intermediary between the robot and the objects, which captures visual information and provides precise data about object positions, shapes, and orientations to the control unit, enabling accurate recognition without direct mechanical contact
Solution Approach 2:
The holding mechanism is designed with multiple degrees of freedom and adjustable grasping forces, allowing it to adaptively stabilize various types of objects including corrugated boxes and commodity packages with different shapes, sizes, and weights using the same robotic system
3Stability of the object's composition
If holding mechanisms are designed for stable picking, then object stability improves, but the complexity of controlling position and posture increases
Solution Approach 1:
The patent implements a feedback control system where the recognition device continuously monitors object position and posture, and the control unit adjusts the holding mechanism's position and orientation in real-time to maintain stable grasping, automatically compensating for variations without complex manual intervention

AI summary
According to one embodiment, a picking apparatus includes a carriage, a holding mechanism, and a movement mechanism. The holding mechanism includes an arm, a rotating shaft provided at one end of the arm and rotating the arm, and a holding part provided at the other end of the arm and able to hold at least one object. The movement mechanism is provided on the carriage, and includes a first movement part that moves the rotating shaft along a first direction toward the object, and a second movement part that moves the first movement part along a second direction intersecting with the first direction and approximately perpendicular to the carriage. The first movement part is positioned along a direction away from the object with respect to the second movement part.
