Author: Smartweigh–Multihead Weigher
The most critical parts in the dynamic multihead weigher are composed of four parts: conveyor, load cell, display controller and rejecting device. Components of the dynamic multihead weigher-conveyor Conveyor is composed of conveying device and weighing unit. There are many types of conveyors, belt type, chain type or roller type can be selected according to the form of the conveyed object.
The size of the conveyor depends on the size of the object being weighed. The dynamic multihead weigher weighing table itself is an independent small conveyor, and the item to be weighed is weighed instantly when the item passes through the conveyor. Due to the dynamic measurement, the measurement speed is relatively high.
The transmission part of the conveyor adopts a three-in-one electric roller, which can make the weighing platform compact in structure, reasonable in layout and beautiful in appearance. The component of dynamic multihead weigher - load cell There are also many forms of load cell, such as: differential transformer type, resistance strain type and electromagnetic balance type. The dynamic multihead weigher uses the applied resistance strain sensor, which has the advantages of low price, many types of products, and good stability.
The weighing platform composed of conveyors is placed on the sensor, and the number of sensors is determined according to the size of the weighing platform. The platform with large weight and large size is supported by 4 sensors, and the performance is stable and reliable; the platform with small range and small size can be Use a single sensor to support the table. The component of the dynamic multihead weigher-display control amplifies the weight signal sent by the weight sensor, performs calculation processing, and digitally displays the weight value, and compares the weight data with the preset value, and then sends out underweight, overweight, and qualified control Signal. Underweight and overweight thresholds can be set manually.
The display control instrument can display gross weight, net weight, the last weighing value, the difference between the last weighing value and the set nominal value. It can also display the total number of pieces weighed, the number of underweight pieces, the number of overweight pieces, and the number of qualified products. The display controller can also deliver a variety of statistical information, and can network the useful information to the management computer through the communication interface or print out the report through the printer.
Components of the dynamic multihead weigher-rejecting device According to the packaging form and characteristics of the inspected items, the rejecting device can be divided into various methods such as pushing out, tipping and falling, handling, diverting, etc., to exclude the detected unqualified items into the production process outside. The above four components are very important for dynamic multihead weigher. It is also the most critical part of the dynamic multihead weigher.
