On-line tare weight subtracting method and system for tobacco packaging

Abstract

Disclosed is an on-line tare weight subtracting method and system for tobacco packaging. The method includes adopting an electronic scale to weigh cartons one by one before empty cartons are fed in for charging, recording weight values on the cartons in a bar code mode, and reading the carton weight values recorded by bar codes and displaying the carton weight values on a large electronic screen during the last process of manually checking the weight values after charging is finished. The method and the system have the advantages that values of gross weight, tare weight and net weight of finished products can be recorded accurately, differences among individuals are eliminated completely, errors between tare weight and net weight due to mistaken using of the cartons are avoided, and doubts of customers are removed completely.

Description

technical field [0001] The invention belongs to the technical field of taring system structure for recured tobacco leaf packaging boxes. Background technique [0002] In the threshing and redrying industry, the finished tobacco leaves are packaged in batches of cartons, and the method of removing the tare of the cartons is a random sampling method, that is, in a batch of production tasks, 15-20 cartons are selected and the total weight is weighed. weight, and then calculate the arithmetic mean value, and use this value as the default tare value of this batch of finished products, and remove this tare value for each finished product. This method has the following obvious disadvantages: [0003] 1. There are often certain differences between individual cartons. Customers feel unreliable for the difference between the average value and the individual, and often ask for re-calculation of the average value after a period of production; [0004] 2. Due to the different specificat...

AI Technical Summary

Problems solved by technology

[0003] 1. There are often certain differences between individual cartons. Customers feel unreliable for the difference between the average value and the individual, and often ask for re-calculation of the average value after a period of production;

[0004] 2. Due to the different specifications of the cartons used in processing, in the production process, occasionally, the cartons of this specification are used to calculate the average, but the cartons of another specification are used in the production process.

The practice of frequent sampling and averaging reduces production efficiency, even if it does this, it cannot eliminate the customer's doubts about the error of the finished product's tare weight and net weight value. What the customer needs is to increase the net weight value of the finished product to a level of trust.
