Robot Hand Adhesion Folding Cardboard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing robot systems for folding cardboard cases have complex configurations due to the use of multiple movable plates and hydraulic or pneumatic cylinders, making them cumbersome for folding foldable portions.
Innovation Solution
A robot system with a hand that holds the article using a rotatable holder for adhesion, and an arm that moves the hand to fold the foldable portions by rotating the holder while keeping it in contact with a contacting portion, simplifying the folding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple movable plates and hydraulic or pneumatic cylinders are used for folding, then the folding function is achieved, but the configuration becomes complex
Solution Approach 1:
The patent extracts the complex folding mechanism (movable plates and cylinders) from the system and replaces it with a simple rotatable holder. The holder is directly rotated by the robotic arm to achieve folding, eliminating the need for separate folding actuators and movable plates.
Solution Approach 2:
The robotic arm is given multiple functions: it not only positions the cardboard case but also performs the folding operation by rotating the holder. This multi-functionality eliminates the need for dedicated folding mechanisms, simplifying the overall system configuration.
2Device complexity
If a rotatable holder with adhesion is used to hold the article, then the folding process is simplified, but the requirement for precise control increases
Solution Approach 1:
The holder uses adhesion (suction) to automatically grip the cardboard case, eliminating the need for complex clamping mechanisms. The adhesive force self-adjusts to hold the article securely during rotation and folding operations.
Solution Approach 2:
The holder is designed to be rotatable rather than fixed, allowing dynamic adjustment of the cardboard case orientation. This rotational freedom enables simplified folding movements while the control system manages the precision requirements through coordinated rotation control.

AI summary
A robot system includes: a hand that holds an article; an arm that moves the hand; and a first contacting portion with which a first foldable portion of the article is brought into contact during a first folding process that is a process of folding the first foldable portion in a state where the article is held by the hand. The hand includes: a base that is connected to the arm; and a holder that is rotatable relative to the base and holds the article by adhesion. During the first folding process, the hand and the arm fold the first foldable portion by rotating the holder while keeping the first foldable portion in contact with the first contacting portion.
