Technical Field

Background

The liquid filling machine is a general name of all equipment used for liquid filling.

All filling equipment is designed by fully considering the characteristics of filling products, and parts contacting with materials are made of 316L stainless steel materials.

For example, the double-head full-automatic piston type liquid filling machine is improved on the basis of the original series of filling machine products, and partial additional functions are added. The product is simpler and more convenient in the aspects of use operation, precision error, installation adjustment, equipment cleaning, maintenance and the like. The filling machine is widely applicable to various industries such as daily chemicals, grease and the like, and can be used for filling fluids with different high viscosities. The machine has compact and reasonable design, simple and beautiful appearance and convenient filling quantity adjustment.

Drawings

Embodiments of the invention will now be described with reference to the accompanying drawings, in which:

fig. 1 is a schematic external view of a streamlined operating system for a compatible adaptive filling system according to an embodiment of the present invention.

Detailed Description

Embodiments of the compatible type adaptive filling system of the present invention will be described in detail below with reference to the accompanying drawings.

The self-adaptive control is the same as the conventional feedback control and the optimal control, and is a control method based on a mathematical model, and the difference is that the prior knowledge about the model and the disturbance, which is the basis of the self-adaptive control, is less, and the information about the model needs to be continuously extracted in the running process of the system, so that the model is gradually improved. Specifically, the model parameters may be continuously identified based on the input and output data of the object, which is called online identification of the system. With the continuous production process, the model becomes more accurate and closer to reality through online identification. Since models are constantly being developed, it is clear that the control actions integrated on the basis of such models will also be constantly being developed. In this sense, the control system has a certain adaptability. For example, when the system is in the design stage, the system may not perform well when being put into operation at the beginning due to the lack of initial information of the object characteristics, but as long as a period of operation elapses, the control system gradually adapts to adjust itself to a satisfactory working state through online identification and control. For example, in some control objects, the characteristics of the control objects may change significantly during operation, but the system can adapt gradually by identifying and changing the controller parameters online.

The conventional feedback control system has a certain inhibiting capability on the influence of the internal characteristic change of the system and the external disturbance, but because the controller parameter is fixed, when the internal characteristic change of the system or the change amplitude of the external disturbance is large, the performance of the system is often greatly reduced and even unstable. Adaptive control is appropriate for systems that vary widely in object or disturbance characteristics, and that often require high performance levels. It should also be noted, however, that adaptive control is much more complex and costly than conventional feedback control, and is therefore considered only when the desired performance is not achieved with conventional feedback.

At present, various assembly line liquid filling systems in use carry out streamlined filling treatment on bottles with the same size, so that the accuracy and reliability of filling can be ensured, but the problem of resource waste can be brought by the filling mode, namely, the compatibility is insufficient, and once filling orders of bottles with different sizes are received, a new assembly line needs to be replaced again.

In order to overcome the defects, the invention builds a compatible self-adaptive filling system, and can effectively solve the corresponding technical problem.

In addition, in the compatible adaptive filling system, Serial Interface (Serial Interface) means data transmission sequentially bit by bit, and is characterized in that a communication line is simple, and bidirectional communication can be realized only by a pair of transmission lines (telephone lines can be directly used as the transmission lines), so that the cost is greatly reduced, and the compatible adaptive filling system is particularly suitable for remote communication, but has a slow transmission speed. The communication method in which each bit data of one piece of information is sequentially transmitted bit by bit is called serial communication. The serial communication is characterized in that: the data bit is transmitted according to the bit sequence, and can be completed by only one transmission line at least; low cost but slow transfer speed. The distance of serial communication can be from several meters to several kilometers; serial communication can be further divided into simplex, half-duplex and full-duplex depending on the direction of information transfer. The initial serial port is used for connecting a mouse, an external Modem, an old-fashioned camera, a tablet and other devices. The serial port can also be applied to interconnection and data transmission between two computers (or equipment). Because serial ports (COM) do not support hot plugging and have a low transmission rate, some new motherboards and most laptops have begun to cancel the ports. The serial port is mainly used in industrial control and measurement equipment and part of communication equipment.
