Description

Automatic mixing system and method for tubular medicines

Technical Field

The invention relates to the field of conveying of rod-shaped materials, in particular to an automatic mixing system and method for tubular medicines.

Background

The key technologies to be solved are automatic mixing technology of tubular medicines:

because of the lack of support of automatic mixing equipment, the tubular medicine production line in China adopts a manual operation mode to mix the tubular medicines. Taking the selection and mixing process of 59-130 gun powder (a screw-pressing double-base tubular powder) as an example, the main equipment, material state and change, the number of operators and special conditions are shown in Table 1.1.

TABLE 1.1 cartridge selection, blending equipment and Material State Change

The main problems of the manual mixing process are as follows:

problem 1: the work site has large production amount of dangerous goods

Usually, the maximum amount of the tubular medicine in one charge batch can reach 70 tons and the tubular medicine is stored in the same workshop, which means that the amount of the medicine to be selected and mixed needs at least more than 70 tons.

Problem 2: the field operating personnel are more

At least 30 people, typically more than 10 dangerous work stations are required to be allocated for the labor order staff according to the batch number of the tubular medicine. In order to reduce the number of field personnel, a three-shift working system is adopted at present, and the number of control operators per shift is 9.

Problem 3: high labor intensity

According to the current operating rules of the tubular medicine manufacturing process, the medicine charge is calculated by 70 tons of inspection amount, 6 absorption medicine batches are required to form (12 tons/batch), the selection amount is about 72 tons, the mixing amount is calculated by three times, at least 70 tons multiplied by 3=210 tons, and the labor intensity is obvious.

Problem 4: the product quality is difficult to guarantee

As mentioned above, because the batch number of the tubular medicines is large, the sizes of the medicines are relatively small (usually the diameter is less than or equal to 10mm, the length is less than or equal to 400 mm), and pure manual operation is added, although the medicine holding amount is about 15 kg once specified by the process in the mixing process, the medicine holding amount in actual operation is more or less, and varies from person to person, and under the condition of limited mixing times, the macroscopic uniformity of the tubular medicines is difficult to ensure to be consistent.

In the storage and transportation industry of the pipe and rod materials, it is known that the material taking and placing of the pipe and rod materials are difficult, time-consuming and labor-consuming. The processes of taking and placing materials, packing the whole box, palletizing and the like are complicated, the whole line occupies large area, consumes time and labor, has high cost and low working efficiency.
