Position-Controlled Linear Actuator for Bottle Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for removing flawed or damaged bottles from a continuous conveyor stream in bottle filling plants require manual adjustment of control parameters and operating pressure, limiting modulation capability and controllability due to variations in bottle size and fill levels.
Innovation Solution
A position-controlled linear actuator driven by an electric linear motor, coupled with a controller, allows for precise adjustment of movement parameters such as force, speed, and acceleration, enabling automatic adaptation to different bottle sizes and fill levels, and includes a sensor for detecting weight and center of gravity to optimize object removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pneumatic pushers are used to remove bottles from the conveyor stream, then the removing function is achieved, but the modulation capability and controllability are limited requiring manual adjustment for different bottle types
Solution Approach 1:
The patent replaces the pneumatic pushing system with a mechanical robotic arm system that uses a gripper to grasp and remove bottles. This substitution enables programmable control and automatic adaptation to different bottle types through sensor feedback and control algorithms, eliminating the need for manual adjustment of pneumatic parameters.
Solution Approach 2:
The robotic system incorporates sensors (optical, tactile, force sensors) that automatically detect bottle characteristics and adjust removal parameters without human intervention. The system self-adapts to different bottle types by receiving feedback from sensors and automatically modifying its control parameters, eliminating the need for operators to manually adjust settings.
2Manufacturing precision
If position-controlled linear actuator with electric linear motor is used, then positioning accuracy and dynamics are improved, but device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical positioning systems with an electric linear motor system that provides direct drive without mechanical transmissions. This substitution achieves high positioning accuracy through electronic control while reducing mechanical complexity by eliminating gears, belts, and other mechanical transmission components.
Solution Approach 2:
The patent introduces a sophisticated control system as an intermediary between the electric linear motor and the robotic arm. This control system processes sensor feedback and generates precise control signals, enabling high positioning accuracy while allowing the motor itself to remain relatively simple in design.
