Movable Guide Members for Container Transfer Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for removing and replacing containers on conveyor lines, particularly for small bottles, fail to provide consistent lateral guidance, leading to potential overturning and require reduced conveyor velocities, which is inefficient.
Innovation Solution
A device with movable guide members that extend between lateral guide walls to ensure continuous lateral guidance of containers, allowing for seamless transfer between the conveyor line and a rotating disc for treatment, and back onto the conveyor line, using suction means and a rotating disc with recesses for container handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lateral guide walls are used without movable guide members, then the device structure is simple, but containers cannot be consistently guided laterally during transit, leading to overturning risk
Solution Approach 1:
The patent applies the dynamics principle by introducing movable guide members that can shift position along the conveyor line. These members move from a retracted position (when not needed) to an advanced position (when containers need guidance during transfer). This dynamic adjustment allows the system to provide lateral guidance only when necessary, preventing container overturning while avoiding the complexity of permanently extended guide structures.
Solution Approach 2:
The guide system is segmented into multiple independent movable guide members rather than a single continuous structure. Each guide member can be independently positioned and controlled, allowing selective guidance in different zones along the conveyor line. This segmentation enables precise control where needed while maintaining simplicity in other areas.
2Reliability
If conveyor velocity is reduced to prevent bottle overturning, then container stability is improved, but operational efficiency and productivity decrease
Solution Approach 1:
The movable guide members are dynamically positioned to provide guidance only during the critical transfer phases when containers are most vulnerable to overturning. During normal high-velocity conveyor operation, the guide members remain retracted and do not interfere with fast-moving containers. This allows the system to maintain high productivity while ensuring stability during vulnerable transition periods.
Solution Approach 2:
The guide members operate periodically, extending to provide guidance only during specific transfer operations and retracting during normal conveyor operation. This periodic engagement allows high-speed conveyor operation for the majority of the time while providing stability support exactly when containers are being transferred and are most at risk of overturning.
3Reliability
If movable guide members are added to ensure continuous lateral guidance, then container stability during transfer is improved, but device complexity increases
Solution Approach 1:
The movable guide members are designed to automatically extend and retract based on the presence and position of containers on the conveyor line. The system self-regulates without requiring complex external control mechanisms, reducing overall device complexity while maintaining reliable transfer stability. The guide members serve themselves by responding to container presence and positioning.
