Embodiment Construction

[0031] A high-speed canning adaptive control system is characterized in that it comprises a front measuring scale, a rear measuring scale, a motion controller, a servo drive, a filling syringe pump and a host computer. The high-speed filling system is connected with the motion controller through the upper computer to monitor the system in real time. The motion controller is connected with the front measuring scale and the rear measuring scale at the same time to obtain the weight data of the filling bottle before and after canning. The motion controller is connected with the servo driver and controls the injection stroke of the filling syringe pump, thereby realizing the control of the filling volume.

[0032] Applying described a kind of high-speed canning self-adaptive control method mainly comprises the following steps:

[0033] Step 1. Set the liquid food canning volume through the human-machine interface module of the host computer, start the system, and control the fill...

Abstract

The invention discloses a high-speed filling self-adaptive control system and method. In order to solve the problem that a manual filling control method is still widely used in a small-dose high-speedliquid food filling machine with high filling precision requirements, and large filling errors caused by characteristic time varying of a filling system are difficult to solve, the liquid food filling system based on weighing self-correction is designed so as to improve the filling precision of the high-speed filling system. On such basis, in order to solve the problem of filling characteristic change caused by system nonlinearity, a self-adaptive intelligent filling control algorithm capable of overcoming time-varying and nonlinear influences is designed. According to the method, the influence of human factors can be avoided, and automatic and high-precision control over an existing filling system is achieved under the condition that the cost is not greatly increased.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to a high-speed canned self-adaptive control system and method. Background technique [0002] The liquid filling control system is a servo control system that controls the stroke of the liquid injection pump and performs automatic filling according to the set value of the filling volume of different liquid foods. It is very difficult to realize high-speed and high-precision automatic filling for a filling system with small filling volume and high filling precision requirements. For this type of high-speed liquid medicine filling machine, the filling accuracy is mainly improved by improving the process and manufacturing level of the filling production line and manually fine-tuning the set value of the filling volume on-line. This method will increase equipment development and maintenance costs, and it is difficult to ensure that a high-precision filling control...
