PLC Weighing System

What Is PLC Weighing System?

Process description of automatic batching system

• There are manual control buttons, indicator lights, and start buttons on the control panel.
• Set the recipe for input ingredients and allocate the required quantity of raw materials proportionally. Provide data basis for automatic feeding.
• At the same time as the production starts, the PLC sends the dynamic measurement start signal to the weighing and measuring instrument. The instrument starts to collect and display the weight of each link and adopts fast and slow feeding strategies at different weight stages, displayed in the form of charts. When reaching the target value, output a stop metering signal, and the PLC controls the closure of relevant valves, pumps, etc. Simultaneously complete the unloading to the reaction kettle, and the measuring instrument will automatically reset to zero and remove the skin.
• At the end of this batch of ingredients, the actual data will be stored by the upper computer and can be analyzed with certain accuracy according to requirements, generating various reports for production statistics and management.
• Print various required reports online or offline, such as daily production of finished products, raw material consumption, raw material inventory, finished product inventory, etc.
• The dynamic weighing instrument of the PLC weighing system adopts a dynamic measurement accuracy control method. When the external operation input signal is valid in the stopped or paused state, the automatic batching process is started.
• After the start of the batching system, the system PLC automatically controls the sequence of opening each raw material pneumatic valve, weighing feeding valve, and feeding motor. After the feeding is completed, the feeding valve and motor are automatically closed, and the unloading valve and mixing motor are opened. The raw materials start to be unloaded, the reaction kettle starts to stir, and the stirring of the reaction kettle ends. The system opens the unloading valve and unloading motor of the reaction kettle, and transports the finished products to the finished product tank. This batching is completed.
• Filling workers can start the filling machine and carry out the barrel-filling process. The batching process can also be manually operated by operators according to process requirements.
• Static level gauges (such as radar level gauges, ultrasonic level gauges, float level gauges, pressure level gauges, etc.) and temperature controllers can be installed on the raw material tank to detect changes in liquid level and temperature at any time. The control system tracks and collects liquid level height data on time, and measures and calculates raw material inventory, feed quantity, discharge quantity, etc., generating data reports for easy management of raw material inventory consumption, etc.

The above is a brief description of the production line of PLC weighing system for a certain customer. Our company can customize it according to different customer needs.

Features of PLC Weighing System

• The PLC weighing system has the characteristics of high reliability, complete functions, and simple programming. It can also be used for batching control of various materials in factories, achieving automation and intelligence throughout the entire process from batching measurement, and mixing, to discharge production. To improve ingredient accuracy, enhance product quality and yield, and reduce costs.
• Simple structure and clear control logic;
• Adopting mainstream products in the field of control (such as industrial computers, Siemens or Omron PLCs, Schneider electrical components, etc.), with good reliability and stability;
• Adopting our company’s unique continuous measurement technology, it has fast efficiency and high accuracy;
• The control panel is centrally operated and controlled, with all instruments visible at a glance, making it easy to monitor and operate. This increases safety and reliability, reduces operator labor intensity, and eliminates the need for operators to travel between scattered weighing instruments;
• The distance between the control console and the control cabinet is close, the transmission distance of control signals is short, and the reliability is strong.

Function of PLC Weighing System

• Display function: The PLC weighing system visually displays the process flow, equipment status, and equipment overview in the form of graphics or images.
• Alarm function: The system automatically performs integer reporting and event processing.
• Data archiving: User Management with Different Permissions.
• Software function: The PLC weighing system can achieve real-time and intuitive monitoring of the production process, various formula management, material shortage reminders, abnormal situation alarms, and other functions.
