The Technology Behind Modern Multihead Weigher Machines

Multihead weigher machines are a vital part of many food processing and packaging operations. They are used to weigh and distribute a wide variety of products, from delicate fruits and vegetables to heavy bags of flour. Modern multihead weigher machines utilize advanced technology to ensure accuracy, efficiency, and reliability.

How Multihead Weigher Machines Work

Multihead weigher machines consist of a series of hoppers, each of which is filled with product. The product is then released from the hoppers and weighed by a series of load cells. Based on the weight of each item, the machine’s computer determines the best combination of items to achieve the desired weight. The selected items are then released into the packaging container.

Advantages of Multihead Weigher Machines

Multihead weigher machines offer a number of advantages over other types of weighing equipment. These include:

Accuracy: Multihead weigher machines are highly accurate, with typical tolerances of ±1 gram. This is important for a variety of applications, including weighing products for sale or for packing into specific containers.

Efficiency: Multihead weigher machines are fast and efficient, with speeds of up to 300 items per minute. This can help to increase productivity and reduce labor costs.

Flexibility: Multihead weigher machines can be used to weigh and bag a wide variety of products. This versatility makes them a good choice for a wide range of applications.

Reliability: Multihead weigher machines are built to last, with robust construction and durable components. This makes them a reliable investment that will provide years of service.

Technology Used in Multihead Weigher Machines

Modern multihead weigher machines utilize a variety of advanced technologies to achieve accuracy, efficiency, and reliability. These technologies include:

Load Cells: Load cells are used to weigh the product as it is released from the hoppers. They are typically made of stainless steel, which is accurate and durable.

Computer Controls: The machine’s computer controls the weighing process and determines the best combination of items to achieve the desired weight. Modern computers are fast and powerful, ensuring accuracy and efficiency.

Sensors: Sensors are used to detect the level of product in each hopper and to monitor the weight of the items as they are released. This information is used to ensure accuracy and to prevent over- or under-filling.

Vibratory Feeders: Vibratory feeders are used to move the product from the hoppers to the weigh cells. They are typically powered by an electromagnetic coil, which creates a vibration that moves the product.

Linear Actuators: Linear actuators are used to open and close the gates on the hoppers. They are typically powered by an electric motor, which provides precise control over the movement of the gates.

Conclusion

Multihead weigher machines are an essential part of many food processing and packaging operations. They offer accuracy, efficiency, flexibility, and reliability, making them a good choice for a wide range of applications. The use of advanced technology in these machines ensures that they are able to perform their tasks with precision and speed.
