The Technology Behind Modern 14-Head Multihead Weighers

Modern 14-head multihead weighers are marvels of engineering that have revolutionized the food processing industry. These machines combine precision weighing, advanced algorithms, and sophisticated software to achieve unmatched accuracy, speed, and efficiency in packaging a wide range of products. This article explores the intricate technology behind these multihead weighers, highlighting their key features and benefits.

Weigh Cell Technology

The core of a multihead weigher is its weigh cells. Each weigh cell consists of a load cell, which measures the weight applied to it, and a strain gauge, which converts the weight into an electrical signal. The weigh cells are strategically placed beneath each hopper, where they continuously monitor the weight of the products being dispensed.

Hoppers and Feeders

Each multihead weigher features multiple hoppers, which are used to hold the products being weighed. The hoppers are filled by a feeder, which vibrates the products to ensure a consistent flow. The feeders are controlled by a central computer, which manages the release of products into the hoppers based on the target weight.

Combination Algorithms

Multihead weighers utilize advanced combination algorithms to determine the optimal combination of products from the different hoppers to achieve the desired weight. These algorithms consider factors such as the weight of each individual product, the number of products in combination, and the target weight. The algorithms are continuously refined through machine learning to optimize weighing accuracy.

Discharge Gates

The discharge gates control the release of products from the hoppers into the weigh pan. These gates are actuated by a central computer and open and close with precise timing to ensure that the correct amount of products is dispensed. The gates are designed to minimize product loss and maintain accuracy even at high speeds.

Weigh Pan and Checkweigher

The weigh pan collects the products dispensed from the discharge gates. The weight of the products in the weigh pan is measured by a dedicated weigh cell. A checkweigher is used to verify the accuracy of the weight and reject any packages that do not meet the target weight.

Advanced Software

The brains of a multihead weigher is its advanced software. This software controls all aspects of the weighing process, from managing the hoppers and feeders to running the combination algorithms and actuating the discharge gates. The software is also capable of data acquisition, diagnostics, and reporting to provide valuable insights into the weighing performance.
