Compact Drum Separator With Auto Flap for Robot Joining Feed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current industrial joining systems face challenges with precise and efficient transfer of joining elements due to complex profile hoses, which are difficult to manufacture and require significant compressed air, leading to air leaks and limited transport distances, and manual filling of separation modules on robots is impractical, causing system stops and safety concerns.
Innovation Solution
A compact device with an automatic flap for the storage container and a compact drum separator driven by an electric geared motor, allowing for short feed hoses and automated filling, preventing joining elements from falling out and enabling robot movement without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual filling of separation modules is used, then employees can refill joining elements, but system stops occur and safety concerns arise due to entry into robot protection circuit
Solution Approach 1:
The filling station is equipped with an automatic flap that opens and closes autonomously based on detection of the separation module's position. When the module is present, the flap automatically opens to allow filling; when absent, it automatically closes. This self-service mechanism eliminates the need for manual intervention, preventing system stops and safety issues while maintaining ease of operation.
2Reliability
If automatic flap with detection is used, then filling is automated and system availability increases, but device complexity increases due to sensors and automated mechanisms
Solution Approach 1:
The patent replaces complex mechanical interlocking systems with a sensor-based detection mechanism. Optical or inductive sensors detect the presence and position of the separation module, triggering the automated flap mechanism. This substitution of mechanical detection with sensor-based detection simplifies the overall system while maintaining automated operation and high reliability.
3Length of stationary object
If feed hoses are made longer to increase transport distance, then joining elements can be transported farther, but compressed air consumption increases and air leaks occur
Solution Approach 1:
The feed system is segmented into multiple sections with intermediate storage points. Instead of using one long feed hose from the filling station to the robot, the system uses shorter hose sections between the filling station and intermediate bunker, and another short section from the bunker to the robot. This segmentation reduces total hose length, minimizing compressed air consumption and reducing the risk of air leaks while still achieving the required transport distance.
