How Vertical Bagger Machines Ensure Accurate Filling

Vertical bagger machines are an essential part of many industrial packaging operations. They are used to fill bags with a wide variety of products, including food, chemicals, and pharmaceuticals. Accurate filling is critical to ensure that the products are packaged safely and efficiently. Vertical bagger machines use a variety of methods to ensure accurate filling, including:

Volumetric Filling

Volumetric filling is a method of filling bags by measuring the volume of the product being filled. This method is commonly used for filling bags with dry products, such as rice, flour, and sugar. Volumetric fillers use a variety of methods to measure the volume of the product, including:

Cups: Cups are used to measure the volume of the product by filling them with the product and then dumping them into the bag.

Augers: Augers are spiral-shaped devices that are used to convey the product into the bag. The speed of the auger is controlled to ensure that the correct volume of the product is filled into the bag.

Vibratory feeders: Vibratory feeders use a vibrating motion to convey the product into the bag. The amplitude and frequency of the vibration are controlled to ensure that the correct volume of the product is filled into the bag.

Gravimetric Filling

Gravimetric filling is a method of filling bags by weighing the product being filled. This method is commonly used for filling bags with liquid products, such as milk, oil, and chemicals. Gravimetric fillers use a variety of methods to weigh the product, including:

Load cells: Load cells are used to measure the weight of the product by supporting the bag and measuring the force exerted on the bag by the product.

Belt scales: Belt scales are used to measure the weight of the product by conveying the product on a conveyor belt and measuring the force exerted on the belt by the product.

Hopper scales: Hopper scales are used to measure the weight of the product by filling a hopper with the product and measuring the force exerted on the hopper by the product.

Combination Filling

Combination filling is a method of filling bags that combines volumetric and gravimetric filling. This method is commonly used for filling bags with products that have a wide range of densities, such as snacks, pet food, and pharmaceuticals. Combination fillers use a volumetric filler to fill the bag with a majority of the product and then use a gravimetric filler to fill the bag with the remaining product. This method ensures that the bag is filled accurately, even if the density of the product varies.

Other Methods of Ensuring Accurate Filling

In addition to volumetric, gravimetric, and combination filling, there are a number of other methods that can be used to ensure accurate filling of vertical bagger machines. These methods include:

Level sensors: Level sensors are used to measure the level of the product in the bag and to stop the filling process when the bag is full.

Overfill protection: Overfill protection systems are used to prevent the bag from being overfilled. These systems typically use a sensor to detect when the bag is full and then stop the filling process.

Bag weighing: Bag weighing systems are used to weigh the bag after it has been filled. This system can be used to ensure that the bag is filled accurately and to reject bags that are underfilled or overfilled.
