How to choose the right checkweigher

If the product meets the specified weight requirements, it is accepted and can continue along the production line. On the contrary, if the product does not reach the desired weight or exceeds certain thresholds, it is removed from the production line through a special selection and ejection mechanism. In this way, the checkweigher ensures that only compliant products are distributed and reach the final consumer, reducing waste and increasing the overall efficiency of the production line.

Within a production line, products can be weighed in two ways: through static scales or through checkweighers, each with distinct characteristics and advantages. Static scales necessarily require intervention by operators, who must manually place the product on the scale for weighing.

Checkweighers, instead, automatically weigh the products while moving along a production line, carrying out a quick and automatic control of the production, without any human intervention. They are suitable for any type of application, with high or low production volumes, high or low sliding speed of conveyor belts.
One of the main advantages of checkweighers is the reduction of weighing time, as manual interaction is not required for weighing products. In addition, process automation increases overall productivity and ensures a 100% inspection rate, reducing human errors and helping to ensure maximum precision and reliability in controlling the weight of products along the entire production line.

• the characteristics of products to be analyzed by the checkweigher scale, because they can directly influence the design and performance of the weighing system. To choose the most suitable machine it is important to evaluate the shape, size, weight, packaging and other factors that define the products. For example, products with particular shapes may require specific measures, such as the addition of side guides, to prevent falling during transport on the belt, while viscous or liquid products, then subject to movement inside the package, will need more attention in the design phase of the machine in order to ensure maximum precision in weighing; 
• production environment and conditions: the environment in which the checkweigher will be used can have a significant impact on system performance. For example, it is essential to take into account factors such as temperature, the presence of dust or vibration and the risk of corrosion, but also consider whether the machine will operate in a high humidity environment or whether it will be subject to water splashes or the accumulation of any residues; 
• evaluation of the available technical characteristics and options: to choose the right checkweigher it is always advisable to carefully evaluate the technical characteristics of each model, such as weighing accuracy, measuring speed, the type of automatic ejectors and the safety devices available. In this way it will be possible to obtain a tailor-made solution that is perfectly suited to the production lines and the application for which it is intended; 
• certification: it is necessary to determine whether the checkweigher should be used for legal trade control (that is MID certified) or for internal use only. If certification is required, the machine must be checked to ensure that it complies with Community and international standards defining the inspection and weighing of pre-packaged products.

Checkweighers offer a number of significant advantages that help to optimize the production process and ensure the quality of the final product. These machines allow products to be weighed with the utmost precision, ensuring that each item meets the specified weight requirements, helping to avoid waste and ensuring compliance with quality standards. The advantages of checkweighers also include:

• efficiency and speed: checkweighers are able to weigh quickly and efficiently a wide range of products. This allows to increase the overall productivity of the production process, reducing machine downtime and increasing the production speed; 
• reduction of product waste: thanks to precision weighing and complete weight control, checkweighers contribute to reducing product waste. This leads to significant economic savings for companies and contributes to improving the environmental sustainability of the production process; 
• traceability and regulatory compliance: checkweigher scales allow accurate traceability of each individual product, ensuring compliance with safety and quality regulations. This is particularly important in high-regulation sectors, such as the food sector and pharmaceutical industry; 
• adaptability to different production lines: checkweighers are available in a variety of models and configurations, which make them suitable for different needs and types of production. This allows companies to find the most suitable solution for their specific needs; 
• reporting and data analysis: these machines are equipped with advanced reporting and statistical data analysis capabilities, which allow you to monitor and evaluate the performance of the production process over time. This can provide valuable information and contribute to the continuous optimization of production. Moreover, if provided with the specific software, it can become a remote control console of all the production machines connected to it, a technology that is recognized as Industry 4.0 and therefore subject to government contributions and other financial benefits; 
• improvement of product quality: thanks to the accuracy in weighing and the complete weight control, checkweigher scales contribute to improving the quality of the final product, thus ensuring a greater level of customer satisfaction and greater loyalty; 
• saving labor costs: automating the production process can reduce the need for manual control of products. This leads to significant savings in labor costs, allowing human resources to be used in other activities.
