Intelligent filling method and system

Abstract

The invention discloses an intelligent filling method. The intelligent filling method comprises the following steps that: an intelligent manipulator is arranged in a filling system, and a pipeline assembly is extruded through the intelligent manipulator to realize metering and conveying during filling; the intelligent manipulator is connected with a control panel, and motion parameters of the intelligent manipulator are set through the control panel. The filling method has the advantages of being high in metering precision, wide in applicability, high in automation degree and intelligent degree and the like. The invention further discloses an intelligent filling system for implementing the intelligent filling method. The intelligent mechanical arm, a backflow preventing assembly, a pipeline assembly and a pipe frame assembly are all integrally installed on a rack assembly. The beneficial effects of being compact in structure, easy and convenient to operate, high in metering precision,convenient to maintain and the like are achieved, and the whole filling system is completely visualized. The probability of finding abnormal filling is improved, and the operation reliability of the filling system is also improved.

Description

technical field [0001] The invention mainly relates to the technical field of filling, in particular to an intelligent filling method and system. Background technique [0002] At present, filling equipment is widely used in the production of fluid products such as pharmaceuticals, beverages, and chemicals. In the production process of products, filling is also a very important link. For fluids with different characteristics, the requirements for filling equipment are also different. Existing filling equipment all adopts pump to convey fluid, to realize filling. When filling with high-precision requirements or filling fluids with special properties, the performance requirements for pumps also increase. [0003] In the prior art, when performing high-precision metering and filling, most of the two types of pumps are plunger pumps or peristaltic pumps. In the process of metering and filling with plunger pumps and peristaltic pumps, there are still some defects that affect th...

Problems solved by technology

[0004] 1. When the plunger pump filling equipment is performing intermittent filling work or metering and transporting special fluids, it is easy to get stuck in the pump and absorb crystals, causing damage to the equipment and scrapping it, which greatly increases the cost; the plunger pump When working, the relative movement between the inner cavity wall of the pump and the plunger will generate shear force, which is extremely destructive to the internal molecular structure of the fluid product, especially in some macromolecular structures or requirements for the integrity of the molecular structure Among high-end products, the plunger pump is difficult to meet the conditions of its filling production

[0005] 2. When the plunger pump is filled, the fluid needs to flow through the pump body. First of all, the compatibility between the material of the pump body and the fluid is a big problem; secondly, the structure of the pump body is complex, and it is also a big problem to prevent the sanitary corners in the pump body from polluting the fluid Due to the complex structure of the pump body and many sanitary dead ends, it is very troublesome to disassemble, clean, and install the pump body; especially when it is used in some high-demand production environments such as biopharmaceuticals, there are risks such as cross-contamination of liquid medicine. more difficult to control

[0006] 3. The peristaltic pump filling equipment mainly realizes filling by squeezing the hose, and then the pump body moves to discharge the liquid in the tube cavity. The suction of the fluid is the negative pressure generated when the hose is elastically restored. And suction; in the production process, the peristaltic pump squeezes the hose quickly, the elastic recovery time of the hose is very short, and the degree of recovery is also quite different, resulting in unstable measurement accuracy; in addition, the hose is subjected to multiple sets of rollers for a long time Extrusion, resulting in large wear and deformation, it takes a lot of time to adjust the accuracy, which consumes labor costs

[0007] 4. The overall volume of the peristaltic pump is relatively large, and the mechanical parts such as transmission parts are all set in the pump body. During the production process of strict pharmaceuticals, biological products or other products with special requirements, when it is necessary to produce and fill in the dynamic A-level area, It is easy to cause pollution in the production area and cannot meet the production requirements of pharmaceuticals or biological products
