Gravity-Fed Spike Tray for Automated Rail Maintenance Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual loading of rail spikes into feed trays is a tedious and labor-intensive task in rail maintenance operations, distracting operators and increasing labor costs, especially when two operators are required for the spiking operation.
Innovation Solution
A spike tray with distinct regions, including an Upper Basket, Orientation Chute, Orientation Twist, and Lower Spike Tray, uses gravity and specially shaped components to orient rail spikes from random orientations to a uniform tip-down, head-up position without operator contact, facilitating automated delivery to a spike feeder magazine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual loading of spikes into feed trays is used, then operators can control the spiking operation, but labor costs increase and operator attention is distracted
Solution Approach 1:
The spike tray system performs self-service by automatically orienting and conveying spikes through gravity-fed mechanisms. The tray structure with its inclined surfaces, guide walls, and rotational zones automatically orients spikes from random positions to the required orientation without human intervention, eliminating the need for operators to manually load spikes while maintaining operational control
Solution Approach 2:
The patent replaces the manual mechanical loading process with an automated gravity-based mechanical system. The tray uses gravitational force combined with specially designed geometric features (inclined planes, guide surfaces, and rotational zones) to substitute human hands and attention with an automated mechanical conveying system
2Reliability
If two operators are provided for spiking operation, then spike loading and driving control are both covered, but labor costs increase
Solution Approach 1:
The spike tray system performs self-service by automatically orienting and conveying spikes through gravity-fed mechanisms. The tray structure with its inclined surfaces, guide walls, and rotational zones automatically orients spikes from random positions to the required orientation without human intervention, eliminating the need for operators to manually load spikes while maintaining operational control
Solution Approach 2:
The single operator gains back time and attention by delegating the spike loading function to the automated tray system, allowing that one operator to focus on the driving control while the tray handles the loading function universally and continuously
3Manufacturing precision
If spikes are manually oriented in proper position, then correct insertion into magazine is achieved, but operator attention is distracted from driving operation
Solution Approach 1:
The patent replaces the manual mechanical loading process with an automated gravity-based mechanical system. The tray uses gravitational force combined with specially designed geometric features (inclined planes, guide surfaces, and rotational zones) to substitute human hands and attention with an automated mechanical conveying system
Solution Approach 2:
The spike tray system performs self-service by automatically orienting and conveying spikes through gravity-fed mechanisms. The tray structure with its inclined surfaces, guide walls, and rotational zones automatically orients spikes from random positions to the required orientation without human intervention
