What is the principle of multi head weigher?

The principle of a multi head weigher involves the use of multiple weighing heads to accurately measure the weight of products in a fast and efficient manner. This technology has revolutionized the packaging industry, providing a highly efficient solution for companies involved in the production of snacks, candies, frozen foods, and various other products. But how exactly does a multi head weigher work, and what are its advantages? Let's dive into this topic in more detail.

1. What is a multi head weigher?

A multi head weigher, also known as a multihead weigher or combination weigher, is a device commonly used in the packaging industry. It features multiple weighing heads mounted on a central frame. These weighing heads simultaneously weigh different portions of the product, ensuring an accurate and consistent weight is achieved. By combining the individual weights, the multi head weigher determines the total weight of the product.

2. Principle of operation:

The operation of a multi head weigher can be divided into four main steps: feeding, weighing, discharge, and control. First, the product is fed into the machine, which can be done manually or automatically through a conveyor belt. The multi head weigher then distributes the products to the individual weighing heads.

Each weighing head measures the weight of its portion of the product. These measurements are continuously fed into a central control system, which calculates the total weight by summing up the individual weights. Finally, the machine discharges the weighed product to downstream packaging equipment, ensuring accurate quantities for the packaged goods.

3. Advantages of multi head weighers:

a. Speed and efficiency: Multi head weighers are known for their high-speed operation, allowing manufacturers to achieve significant improvements in productivity. With multiple weighing heads working simultaneously, these machines can handle a large quantity of products in a short period.

b. Accuracy: Accurate weighing is essential in the packaging industry to comply with regulations and meet customer requirements. Multi head weighers excel in this aspect, thanks to their ability to distribute the product evenly among the weighing heads and calculate the total weight with precision.

c. Versatility: Multi head weighers can handle a wide range of product shapes and sizes, making them suitable for various industries. Whether it's irregularly shaped snacks, granular products, or delicate goods, these machines can adapt to different products and packaging needs.

d. Flexibility: Manufacturers can program multi head weighers to produce different package sizes and weights, providing flexibility in the production process. This feature is particularly useful when catering to diverse customer demands, allowing for quick changes in packaging specifications.

e. Reduction in waste: Overfilling or underfilling packages can result in unnecessary waste, costing both money and resources. Multi head weighers are designed to minimize such waste by precisely measuring the required weight for a specific package size. This accuracy reduces product loss, contributing to a more sustainable and cost-effective operation.

4. Conclusion:

In conclusion, the principle of a multi head weigher revolves around the use of multiple weighing heads to measure the weight of products accurately. This technology offers numerous advantages, including speed, accuracy, versatility, flexibility, and waste reduction. With the ability to handle various product types and package sizes, multi head weighers have become an invaluable asset for the packaging industry. By embracing this innovative solution, manufacturers can enhance their productivity, meet customer expectations, and streamline their packaging processes.
