Cable Supply Buffer Control for Constant Output Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable supply systems struggle to maintain a constant cable output speed due to variations in cable coil diameter and supply speed, leading to inconsistent cable delivery.
Innovation Solution
A cable supply system comprising a cable supply device, a cable buffer device, and a control device that dynamically adjusts the cable storage amount in the buffer device to match the supply speed, ensuring a constant output speed by controlling the movement of a movable pulley relative to a fixed pulley and using a control device to regulate the cable supply and buffer device operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cable supply reel is rotated to release the cable, then the cable can be supplied, but the cable output speed varies continuously due to changing cable coil diameter
Solution Approach 1:
A cable buffer device is introduced as an intermediary component between the cable supply reel and the cable usage point. The buffer device includes a movable pulley that can shift position to absorb or release cable, acting as a mediator that decouples the variable supply speed from the constant required output speed. The control device monitors output speed and adjusts buffer positioning to maintain stable cable delivery.
2Quantity of substance
If the cable coil diameter decreases during uncoiling, then the cable supply reel can be emptied, but the cable supply speed changes continuously
Solution Approach 1:
The cable buffer device employs a movable pulley that dynamically adjusts its position based on real-time cable supply conditions. As the cable coil diameter changes during uncoiling, the movable pulley shifts to compensate for the speed variation, maintaining a relatively constant cable output speed throughout the entire uncoiling process until the reel is empty.
3Stability of the object's composition
If a cable buffer device is added to stabilize output speed, then cable delivery consistency improves, but device complexity increases
Solution Approach 1:
The cable buffer device is designed with a movable pulley that can automatically adjust its position based on cable tension and supply conditions. The control device monitors output speed and autonomously adjusts buffer positioning without requiring complex external intervention, allowing the system to self-regulate and maintain stable cable delivery while minimizing overall system complexity.

AI summary
A cable supply system includes a cable supply device supplying a cable, a cable buffer device storing a portion of the cable supplied from the cable supply device, and a control device controlling a cable storage amount of the cable buffer device. The control device controls the cable storage amount of the cable buffer device according to a cable supply speed of the cable supply device such that a cable output speed output from the cable buffer device is equal to a predetermined speed.
