The filling machine sends the barcode data to the server by weighing module to get the barrel file data, and then sends it down to the filling scale through the weighing module. It adopts Profibus system configuration with PLC controller as the master and ET200 distributed I/0 as the slave to realize the control of the electronic scale, frequency converter and centrifugal pump as well as the monitoring of the level of each barrel and the manipulator. It accomplishes the functions of status monitoring, alarm display and manual operation of the metering and conveying process.

The filling machine consists of S7-200PLC and weighing instrument ICS241 and filling solenoid valve. PLC uses RS232C communication port to connect with the weighing instrument to collect and process the weight data through communication, as well as send tare signal to make the instrument tare. In the quantitative filling mode, PLC as the main controller receives the data from the weighing instrument, processes the data and sends a series of signals to control the action of the filling machine, so that the filling machine completes the quantitative filling.

Quantitative filling machine filling adopts stepping motor to drive the filling valve up through the screw according to the pre-set speed: when the filling requirement is reached, the filling is closed. Adopting automatic capping, capping, sealing one by one, the filled pail is accurately sent to the automatic capping machine, the capping machine, through the robot, sucks up one pail cap each time and accurately places it on the top of the filled pail, and the automatic sealing machine will immediately cooperate with the action of the pail cap to accurately squeeze the pail cap, sealing the filled pail.

Quantitative filling machine for the full Chinese liquid crystal display, quantitative value can be changed according to the need, filling is automatically stacked into the pallet, filled barrels through the sealing package, passed to the automatic stacking machine under. Through the professional manipulator, the filled drums are accurately sucked and placed into the set pallet. When the number of buckets in the pallet reaches the specified number, the robot will automatically transport the pallet with buckets to the specified position.

Quantitative filling machine consists of cylinder actuator and weighing module, which is used to monitor the assembly line filling device and related data management to ensure that the equipment to complete the expected operation, and its main function is to achieve accurate measurement of the product material, and the equipment consisting of heating mechanism, automatic capping mechanism, transmission mechanism and other units to complete the work of the product packaging, coding printing, and transportation of finished products.

Automatic filling machine to realize the instrumentation and PLC and the host computer communication connection, real-time processing and the corresponding components of the formula for comparison of the settings. The use of RS485 bus type to realize the connection with the filling machine port, in order to achieve the instrumentation and PLC and the host computer running state is consistent, read through the interface stored in the filling machine touch screen, easy to fill management and query.

The dosing system is usually used for batch mixing of more than two kinds of raw materials in proportion, and the program control makes the batch mixing do continuous action, so as to achieve the uniformity of the mixing ratio performance. The human-machine interface is used to input the corresponding proportioning parameters, and the signal of each sensor is transmitted to the weighing instrument through the weighing module, and then the signal is converted by the weighing instrument and connected to the central controller, which, in combination with the set formula and according to the real-time data of each weighing unit, controls the dosing time and amount of dosing of each kind of material, and all the raw materials enter into the horizontal mixing machine after the weighing is finished.

Weighing and batching system is composed of computer and PLC, weighing instrument, weighing module and signal distributor, PLC is used to configure switching control such as starting and stopping and opening and closing of the warehouse door, detecting the state of the warehouse door and running configuration, and carrying out system interlocking of the batching system. PLC and weighing control instrument are connected by I/O collar, and directly join in the batching control. PLC and weighing control instrument are connected by I/O, directly joining the batching control. It has the results of weighing signal collection, fast and slow adding control and self-tuning of overshoot, etc. It can modify the input and parameters of the material side. Each scale is equipped with three weighing modules, whose signals are fed into the distributor, connected in parallel to the bridge wall, and the voltage is divided and sent to the weighing instrument.

The automated feeding system is controlled by PLC timing, the mixer is always stirring, the liquid is added quantitatively when mixing, the silo must be released when the hopper door is closed (if the hopper is equipped with a weighing scale) and the scale is empty. The hopper will start to release material after the bin is closed in place. External storage tanks and internal silos start to feed material to the screw after a delay, the amount of material to be fed is controlled by the opening of the material door, and the starting and stopping is controlled according to the start and end of the discharge of material from the hopper. All controls are interlocked by PLC, which controls the start and stop.
