Automatic filling machine adopts three-stage feeding and filling control to realize fast, medium and slow control of valve closing, PLC signal control cylinder stroke to complete the weighing, filling, capping, valve opening, valve closing, capping and other actions set of control of plastic barrel disinfection, bottle delivery, quantitative filling, cap delivery and cap rolling and other functions in one. In normal operation, the liquid material flows from the storage pool through the feed pump to the high level storage cylinder, and the barrel is sent to the weighing platform manually, the opening cylinder moves to the given position and catches the valve seat, the opening cylinder moves downward, and the opening cylinder provides the force to take down the valve port, and the opening cylinder returns. Open valve cylinder rises and rely on open valve cylinder force top open filling head sealing device, start filling and metering, weighing module metering to reach a given weight value, open valve cylinder back to fill valve closure cover cylinder movement to a given position, open valve cylinder upward movement, the valve cover is mounted.

Liquid filling machine production line controlled by the frequency converter continuous rotary operation of the disk using barrel positioning technology to achieve the control of barrel feeding, rotary disk the entire circumference is evenly divided into groups, each group has more than one to be filled barrels at the same time to be filled, when the filling signal arrives, a number of filling needles by the rotary disk to coordinate the operation of the cam mechanism to control the drop to a certain depth of a number of barrels, and at the same time to follow the synchronous operation of rotary disk and filling, quantitative filling, quantitative filling, filling, and filling, the filling cylinder to close the cap cylinder movement to a given position, the cap is loaded. Filling, quantitative filling is completed by a number of filling needle by the cam mechanism to lift to completely detach from the filling barrel and quickly swing back to the initial position, and wait for the next set of empty barrel filling, filling barrels are conveyed to the capping link for processing, so that the filling system to complete a cycle of action. Digital signal processor DSP motion controller, combined with Yaskawa AC servo units and servo motors, composed of a set of adaptability and flexibility of the servo control system to replace the cam feed and fast swing function. In order to reduce the system on the drive power requirements, reduce engineering costs and ensure that the system can drive the load for rapid acceleration / deceleration movement, the load drive link adopts synchronous toothed belt by stepping wheel speed reduction transmission device, synchronous toothed belt speed reduction device with elasticity and damping characteristics, not only on the vibration of the isolation effect, but also reduces the load to the motor to the inertia of the rotating load, but to improve the load drive link order, increase the control difficulty. Control difficulty. Liquid filling scale position tracking performance and its ability to suppress periodic interference signals is the filling needle to the filling barrel of the horizontal position tracking system is to realize the premise of vertical filling guarantee. Due to the needs of production efficiency and filling quality, the filling system is running faster and faster, the higher the horizontal position tracking accuracy, the smaller the caliber of the barrel to be canned, the higher the tracking accuracy of the system. For the automatic filling machine requires the horizontal position tracking system control algorithm is simple, real-time and high precision of the actual situation, proposed to combine the PID control and improve the double repetition control, the use of their respective advantages to constitute a composite control strategy based on the double repetition control and PID control, the use of genetic algorithms for PID parameter rectification, the introduction of the PD (proportional, differential) link in each repetition of the controller channel.

Weighing and filling machine through the cylinder to drive a piston to extract and hit the material with a check valve to control the flow of material, with a reed switch to control the cylinder stroke to regulate the amount of filling, the use of weighing module and weighing instrument with a data line connection, in the process of measurement of the pressure signal of the electronic scale is constantly transmitted to the weighing instrument, in order to reach the preset quantitative weight to control the instrument to control the stopping of the pump, close the pneumatic valves. Weighing and filling machine is controlled by PLC programmable device, when the container is fed into the scale body motorized drum runs at the same time, the photoelectric switch on the weighing module detects the signal sent by the container passing through, and controls the motor to stop the container when it reaches the filling position, and then the PLC controls the motorized rollers to stop and tare the container automatically, and the filling valve is driven by the stepping motor to drop down to reach the lower limit, and the well is sent out by the travel switch to send out a signal, and PLC controls the filling valve to be fully opened for filling. The filling valve is fully opened for filling. When it reaches the set value, the solenoid valve action, filling valve half open for filling, filling at the same time stepper motor according to the pre-set speed through the screw drive filling valve rise: when the filling requirements are met when the filling is closed, the filling valve reaches the upper limit position travel switch stops and sends out a signal. the PLC at the same time to control the motor motorized scales motorized rolling Jane at the same time, the output of finished products, and then will be placed into the container electronic scales platform, the mouth of the barrel aligned with the filling nozzle, at this time the program starts. Filling nozzle, the program starts, the filling nozzle automatically drop, open the filling valve feed, when the set amount is automatically stop filling, filling nozzle rise, complete the filling process.

The automatic filling machine system for filling lines consists of a total of 20 linear motor modules, each 25 centimeters long, semi-circular shapes used as curved modules, and 30 actuators with semi-circular workpiece holder fixtures. The final result is an elliptical track about 3 meters long. The entire system - with a trajectory speed of 1.5 m/s and a maximum acceleration of the movers of 10 m/s2 - is controlled via a C6920 control cabinet PC with a cycle time of 2 ms. 10 bottles are filled in batches at standstill to be able to meet the required process requirements. The containers are then sealed by a rotational process, which is a continuous process. modules of 10 pieces must be synchronized with the continuous sealer in a relatively short time and at a distance of less than 1 meter. During the filling process, the ten fixtures waiting for the filled bottles are arranged side by side without a single gap in between. However, they must be equidistantly spaced when entering the sealing machine. This also applies to the distance between the two sets of components that each contain ten fixtures; there should be no gap between the two sets. These are ideal applications for filling systems.

Weighing the filling machine in the filling area number of 10 bottles in one group, the sealing machine has another group in the synchronization phase, and a third group from the sealing process unloaded or returned to the canning area, further optimize and better utilize the performance reserves of the automatic filling machine to save more movers and thus reduce costs. Enabling the process sequence to be mapped in such a way that the automatic filler can replicate the slowest sub-processes, thereby significantly improving overall processing speed. These typical examples are more complex, and therefore time-consuming closure mechanisms or additional processing steps due to retrospective product modifications can occur during the development of a filling system.
