Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conveyor drive fabric dyeing machines, achieving synchronization between the operation speeds of the fabric guide and conveyor is challenging, particularly when dealing with varying fabric lengths and weights, leading to potential fabric entangling or jamming and inefficient machine operation.
Innovation Solution
A computer or programmable logic controller (PLC) control unit is used to automatically compute and control the speed of both the fabric guide motor and conveyor motor based on fabric length or weight data, ensuring synchronized operation by adjusting their speeds to a predetermined ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment is used for synchronization, then the machine can operate with fixed fabric length, but the adjustment is time-consuming and difficult
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated control system comprising a computer or PLC control unit that automatically computes and controls the speeds of fabric guide motor and conveyor motor based on fabric length or weight data, eliminating manual intervention and significantly reducing adjustment time
Solution Approach 2:
The control system enables the machine to automatically adjust its own operation parameters by computing the predetermined speed ratio between fabric guide and conveyor based on input fabric data, making the system self-regulating without requiring external manual adjustment
2Adaptability or versatility
If fixed fabric length is used, then synchronization is easier to achieve, but the machine cannot handle varying fabric lengths and weights
Solution Approach 1:
The patent implements dynamic speed control where the control unit continuously adjusts the speeds of fabric guide motor and conveyor motor based on varying fabric length or weight data, maintaining the predetermined speed ratio dynamically rather than statically, thus ensuring reliable synchronization across different fabric specifications
Solution Approach 2:
The system changes operational parameters (motor speeds) based on input fabric parameters (length or weight), using the control unit to compute and adjust speed values dynamically, allowing the machine to adapt to varying fabric characteristics while maintaining reliable synchronization through calculated speed ratios
3Productivity
If automatic control is implemented, then operation synchronization is achieved regardless of fabric length, but the device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it receives fabric data input, computes speed ratios, controls both fabric guide motor and conveyor motor, and handles various fabric specifications, consolidating multiple control tasks into a single multi-functional device that improves productivity without proportionally increasing overall system complexity
Solution Approach 2:
The computer or PLC control unit acts as an intermediary between fabric data input and motor control execution, automatically computing and translating fabric specifications into appropriate speed commands for the motors, thereby managing system complexity through intelligent mediation rather than complex mechanical linkages

AI summary
Disclosed is a control method for synchronized fabric circulation in a conveyer drive fabric dyeing machine. During a dyeing process of fabric, the fabric is driven by a fabric guide to move in a circulating manner and the time period for a cycle of circulation is set in consistency with the time period that a conveyor moving from a rear end to a front end so as to achieve synchronization that makes the circulation smooth. The control method is performed with a computer or a PLC control unit that is supplied with fabric length data or fabric weight data and fabric unit weight data and, based on such data, performs an automatic operation of computation and supply of a signal to speed controllers of the fabric guide motor and the conveyor motor to set the speeds thereof at a predetermined ratio with respect to each other for synchronized operations.
