Error-proof and fool-proof control method and system for batching and weighing

Abstract

The invention discloses an error-proof and fool-proof control method and a system for batching and weighing. The method comprises the steps of: establishing a formula database by a computer; establishing a formula component acquiring calculator associated with the database; inputting the code of a formula to acquire the proportions and the weights of corresponding components; a weighing system capable of alarming and printing and controlled by a PLC performing weighing, and printing and posting the weighing result; creating a retrospective report; and stirring the mixing at regular time and constant speed. According to the error-proof and fool-proof control method and the system for batching and weighing, the consistency, synchronization and confidentiality of formula management are enhanced; the error of formula and the error of instruction are prevented; the batching error caused by manual accounting error is avoided; the deviation caused by excessive measurement fluctuation is reduced, and the consistency between the actual product and theoretical formula performance is ensured; the mixing stirring time is shortened to control the deviation caused by excessive fluctuation; and the stability of the preparation process and the stability of the product quality are ensured.

Description

technical field [0001] The invention belongs to the field of batching and weighing preparation, and in particular relates to an error-proof and fool-proof control method and system for batching and weighing. Background technique [0002] In the quality management of product production, controlling quality cannot only inspect the final product. If the raw materials and production process and specifications cannot be controlled, a large amount of inspection costs will be invested to find and reject unqualified products, and discarding and scrapping unqualified end products will also cause a lot of time and cost waste. With qualified raw materials and production process standards, it does not mean that there will be qualified products, because it is not enough to rely entirely on manual and document systems for overall production management, and it cannot guarantee the consistent quality of each batch of products. Taking the production of glue preparation as an example, the qu...

Problems solved by technology

Since the weighing and batching process must adapt to the requirements of adding more varieties, less addition, high weighing accuracy, and short weighing cycle, the ingredients commonly used today are all artificial ingredients, which requires operators to have a sense of responsibility and quality awareness. Higher, in the actual production process due to human factors such as mismatch, omission, low weighing accuracy and other phenomena seriously affect the quality of ingredients

[0005] Although many companies adopt double-check operations, which can reduce the error rate to a certain extent, but it increases labor costs, and manual recording of weighing results is prone to errors and inconvenient for quality traceability.
