Robot Gripper Deposition for Product Stacks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for handling and moving stacks of printed and folded products, such as those in the graphic industry, are labor-intensive and prone to straining workers, and current robotic solutions do not efficiently allow for automated, disturbance-free deposition of stacks in turned or unturned arrangements.
Innovation Solution
A method using a robot with an articulated arm and two grippers to selectively turn and deposit stacks of products by removing the grippers horizontally in two perpendicular directions, allowing for automated handling and deposition without disturbance or collision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual handling of stacks of products is used, then flexibility in deposition arrangement is maintained, but labor intensity increases and worker strain occurs
Solution Approach 1:
The system uses sensors to automatically detect the presence and position of stacks on the conveyor belt, eliminating the need for manual monitoring and adjustment. The robot autonomously navigates and deposits stacks according to pre-programmed patterns,实现ing self-service operation that maintains flexibility while improving efficiency
Solution Approach 2:
The deposition pattern parameters (positions, orientations, spacing) can be dynamically adjusted through software control without changing the physical system. This allows flexible adaptation to different stack sizes and deposition requirements while maintaining automated high-speed operation
2Device complexity
If a single gripper is used to deposit stacks, then device complexity is reduced, but collision and disturbance during deposition increases
Solution Approach 1:
The deposition action is segmented into two independent phases: one gripper holds the stack while the other gripper is positioned to receive it. This segmentation allows the receiving gripper to be precisely positioned without disturbing the held stack, ensuring disturbance-free transfer
Solution Approach 2:
The second gripper acts as an intermediary between the held stack and the final deposition location. It receives the stack from the first gripper and places it on the conveyor belt, preventing direct contact that could cause disturbance or collision
3Productivity
If automated robotic handling is implemented, then productivity increases, but the ability to handle turned or unturned stacks efficiently is limited
Solution Approach 1:
The robot arm and grippers are dynamically controlled to adjust their position, orientation, and speed in real-time based on the stack characteristics and desired deposition pattern. This dynamic control enables efficient handling of both turned and unturned stacks at high speed
Solution Approach 2:
The robotic system is designed with universal capabilities to handle stacks in multiple orientations (turned and unturned) using the same hardware platform. The deposition pattern can be programmed to accommodate different product types and arrangement requirements, achieving multi-functionality

AI summary
A stack of products is moved using a robot. The robot has an articulated arm and grippers on the articulated arm to grip the stack of products. The stack of products is selectively turned in the depositing scheme. Two grippers are used in the method and, upon the deposit, the grippers are removed from the stack of products in the horizontal and in two directions perpendicular to one another. It is possible to move and selectively deposit stacks of product in a turned or unturned orientation.
