Flat Knitting Machine Goods Flow Card Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method of creating and managing goods flow cards for production lots on flat knitting machines is prone to damage or loss as they need to be stored on the machines until processing is complete.
Innovation Solution
Generating and printing goods route cards directly on the flat knitting machine after production, allowing electronic data transmission and real-time monitoring, with options for data modification and error reporting, and enabling automatic deletion and central system updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If goods flow cards are created manually or printed centrally and stored on flat knitting machines until production is complete, then all production information is available on the cards, but the cards are exposed to damage or loss risk
Solution Approach 1:
The patent creates a copy of the goods flow card data directly on the flat knitting machine's display screen. The original card data is transmitted electronically to the machine, where it can be viewed and processed without physically handling the original card, thereby eliminating the risk of damage or loss during production.
Solution Approach 2:
The patent replaces the mechanical system of physical card handling and storage with an electronic display system. The goods flow card information is shown on the machine's screen, eliminating the need for physical cards to be present on the machine during production, thus removing the vulnerability to physical damage or loss.
2Productivity
If goods flow cards are transmitted electronically to flat knitting machines, then data management efficiency is improved, but the system complexity increases
Solution Approach 1:
The patent utilizes the existing control system and display screen of the flat knitting machine to display goods flow card information. By making the machine's electronic system multi-functional (both knitting control and information display), the patent avoids adding separate complex electronic transmission equipment, thus improving productivity without significantly increasing system complexity.

AI summary
The method involves inputting data of product flow card (7) that is relative to the productive task of the client in the computer system (1). A flat-bed machine is contacted by the computer system, and the data of product flow card is transmitted to a control unit. A production batch belonging to the product flow card is weaved by flat-bed machine and the product flow card is printed on the flat-bed machine. The accomplishment of production batch is reported to the computer system by the control unit of the flat-bed machine and is displayed on the flat-bed machine.
