Introduction
Paste syrup products have always been important pharmaceutical products. With the continuous development of the market, the continuous growth of market demands, and the increasingly worn out and old equipment, the original production technology can no longer meet the market requirements for product quality and output. In order to further improve production efficiency and product quality, the pharmaceutical industry will introduce automatic filling machines into production and increase the capacity of the filling production line.
Problem analysis
The introduction of the filling production line liberated productivity to a certain extent and improved the product quality of the company. However, in the actual production process, it was found that although the filling machine saved manpower and material resources to a certain extent, there were still some problems such as uneven filling weight, declining product qualification rate and so on, which could not meet the product quality and qualification rate required by the company. At the same time, there are still some potential safety hazards, mainly reflected in the following three aspects.
1. The high position of the liquid medicine storage box in the filling production line makes it difficult for workshop workers to add liquid medicine, resulting in the waste of manpower and material resources.
2. The unstable liquid level in the liquid medicine storage tank leads to unstable filling quantity and high product unqualified rate. At the same time, manual inspection and rework are used, resulting in a waste of manpower and material resources.
3. The temperature of the liquid medicine is high, which makes it difficult for workers to operate during dosing, and easy to bring personal and production safety risks.
The production process of the imported filling production line: manual feeding, liquid medicine storage box and bottle sorting, canning, capping, labeling and finished products.
Equipment process and upgrading
The production process of the filling production line is to manually fill the liquid medicine into the storage box of the filling machine; inject the liquid medicine into the cleaned and sterilized medicine bottle through the filling machine, and screw the cap. After the label inspection, the product is finished. Among them, filling, bottle sorting, capping and labeling are all completed automatically by the production line, which has high accuracy in good quality. Charging and inspection are completed by manual operation. The inspection process is relatively simple, mainly to check the physical appearance such as product label and appearance uniformity. There are some problems in the charging process, mainly as follows:
1. The high position of the liquid medicine storage box brings production problems and potential safety hazards.
2. Improper operation or lack of operation awareness by operators leads to different liquid levels in storage tanks for a long time, which is also the reason for the high product unqualified rate.
The production and safety problems in the filling production line are caused by the low degree of automation in the filling process and the high position of the medicine storage tank. Therefore, the key to solving the problem is to realize the upgrading transformation from manual storage to automatic storage. The upgrading idea of filling production line is as follows.
The idea of upgrading the canning production line: Medicine tank 1, medicine tank 2 and medicine tank 3 are connected with the liquid supply pump together. After automatic material storage, they go to the medicine liquid storage box of the filling machine and arrange the bottles at the same time. Next, after canning, capping, labeling, the products are finished.
