What is a Multi-Head Combination Weigher and Why is it Essential?

Decoding the Technology Behind Accurate Weighing

A multi head combination weigher is an automated weighing machine designed for high-speed, high-accuracy weighing of a wide range of products. Unlike traditional linear weighers that measure one batch at a time, a multi-head weigher uses multiple weigh hoppers (typically between 10 and 24, but sometimes more) arranged in a circular pattern. Product is fed from a central dispersion cone into radial feeder pans, which then move the product into individual weigh buckets. The weigher's control system rapidly calculates the best combination of weights from these individual buckets that add up to the target weight with minimal deviation. This 'combination' principle allows for unparalleled precision and speed, significantly reducing product giveaway and increasing throughput. The sophistication of this technology makes it an essential component for modern packaging lines striving for excellence.

The Core Benefits for B2B Operations

Investing in a multi head combination weigher brings a multitude of benefits that directly impact a company's bottom line. The most significant advantage is the drastic reduction in product giveaway.

Modern weighers can achieve accuracies within fractions of a gram, significantly reducing giveaway. When evaluating a potential purchase, consider the desired packaging speed in bags per minute (BPM) or containers per minute (CPM), and the acceptable weight tolerance for your products. Kenwei multi-head weighers are renowned for their balance of high speed and high precision, designed to meet rigorous industry standards.

Assessing Weigher Capacity and Throughput Requirements

Capacity refers to the maximum weight each weigh bucket can hold and the total target weight of the package. Throughput refers to how many weighing cycles the machine can complete per minute. These factors are directly related to your production volume and the size of your packages. A weigher with 10 heads might suffice for lower production volumes or smaller target weights, while a 14-head or 20-head multi head combination weigher might be necessary for higher output or larger pack sizes. It’s crucial to assess your current and projected production demands to select a machine with adequate capacity and throughput to avoid bottlenecks and maximize operational efficiency. Over-specifying can lead to unnecessary costs, while under-specifying will limit your growth.
