How Single Pouch Packing Machines Ensure Accurate Filling

Single pouch packing machines are designed to provide accurate filling of products into pre-formed pouches. This is achieved through a combination of advanced technologies and features that work together to ensure precision and consistency in the filling process.

Volumetric Piston Fillers

Volumetric piston fillers dispense a predetermined volume of product into each pouch. The piston moves within a cylinder, drawing the product into the filling chamber and then dispensing it into the pouch. The volume of the piston’s stroke is precisely calibrated to deliver the desired amount of product.

Load Cells and Feedback Control

Load cells are used to measure the weight of the filled pouch and provide feedback to the machine’s control system. This allows the machine to adjust the filling volume in real time, compensating for any variations in the product’s density or weight.

Auger Fillers

Auger fillers use a rotating auger to dispense products into pouches. The rate of auger rotation and the pitch of its flights are carefully designed to deliver the desired amount of product per revolution. The auger speed is controlled by a variable frequency drive, allowing for precise filling.

Net Weight Fillers

Net weight fillers operate by weighing the product as it is filled into the pouch. A load cell integrated into the filling head continuously measures the weight of the product, and the machine stops filling when the desired weight is reached. Net weight fillers are highly accurate, even for products with varying densities.

Level Sensors and Servo Drives

Level sensors are used to monitor the product level within the filling head. When the product level drops below a predetermined threshold, the machine automatically activates a servo drive to refill the head. Servo drives provide precise control of the refill process, ensuring that the correct amount of product is dispensed into each pouch.

HMI and Data Logging

Modern single pouch packing machines are equipped with human-machine interfaces (HMIs) that provide real-time monitoring of the filling process. The HMI allows operators to adjust parameters, track performance, and diagnose any potential issues. Data logging capabilities enable the machine to record filling data for quality control and analysis.

Single pouch packing machines are precision engineered to ensure accurate filling of a wide range of products. By utilizing advanced technologies such as volumetric piston fillers, load cells, auger fillers, net weight fillers, level sensors, and servo drives, these machines provide reliable and consistent filling performance. The use of HMIs and data logging capabilities further enhances the accuracy and efficiency of the filling process.
