Production Data Linking for Combination Weighing Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing production management systems require manual sampling inspections to verify combination weighing apparatuses, which are inefficient and do not effectively manage upstream process information.
Innovation Solution
A production management device and system that integrates communication and storage capabilities to associate weighing values with identification information, allowing automated tracking and management of production data across the production line, reducing the need for manual inspections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual sampling inspection is performed to verify combination weighing apparatus, then measurement precision can be ensured, but productivity decreases due to time-consuming manual operations
Solution Approach 1:
The system creates a digital copy of the weighing data from the combination weighing apparatus and stores it in association with packaging material identification information. This digital copy replaces the need for physical manual inspection, allowing verification through data retrieval rather than manual measurement, thus maintaining measurement precision while dramatically improving productivity
Solution Approach 2:
The manual mechanical inspection process is replaced by an automated information management system that electronically stores, retrieves, and associates weighing data with packaging materials. This substitution eliminates manual labor while preserving the accuracy of original measurements through automated data management
2Loss of information
If conventional recording device is used to manage inspection results, then loss of information is reduced for downstream processes, but adaptability decreases because it cannot handle upstream process information
Solution Approach 1:
The information management system is designed to handle multiple types of process information from different stages of production. By associating weighing data with packaging material identification, the system becomes universal enough to manage both upstream (weighing) and downstream (packaging, inspection) information, eliminating the limitation of conventional devices that could only handle downstream information
Solution Approach 2:
The packaging material identification information serves as an intermediary key that links upstream weighing data with downstream packaging and inspection data. This intermediary enables the system to integrate information across different process stages, making the recording device adaptable to handle comprehensive production information
3Productivity
If automated data management is implemented to reduce manual inspection, then productivity increases, but device complexity increases due to integration requirements
Solution Approach 1:
The automated system is segmented into distinct functional modules: a communication section for data acquisition, a management section for data processing and association, and a storage section for data retention. This segmentation allows each module to perform its specific function independently, reducing the perceived complexity while achieving high productivity through automated operations

AI summary
A production management device includes: a communication section provided to enable communication with a combination weighing apparatus and a bag-making and packaging apparatus; a management device provided to enable communication with the combination weighing apparatus and the bag-making and packaging apparatus via the communication section; and a storage device configured to store therein various information. The management device generates and stores production information in the storage device. In the production information, a weighing value of articles weighed by the combination weighing apparatus, the weighing value being output at discharge timing at which the combination weighing apparatus discharged the articles to the bag-making and packaging apparatus, is associated with identification information given to a packaging film of the articles, the identification information being output at packaging timing at which the articles discharged at the discharge timing were packaged by the bag-making and packaging apparatus.
