Checkweighers

62 Machines
Checkweighers, also called weighing sorters, are automatic machines for controlling the weight of various products, ensuring quality compliance and filling accuracy on automatic packaging lines. Makinate offers a wide selection of used checkweighers for weighing bottles, cartons, and individual products, providing reliable solutions for the pharmaceutical, nutraceutical, cosmetic, food, and industrial sectors.

How checkweighers work

Checkweighers are essential product control instruments used to verify the weight of already packaged products with very high precision.... These machines integrate perfectly into automatic packaging lines and are a key component in ensuring that each product meets established weight parameters, ensuring regulatory compliance and final customer satisfaction.

Selection criteria

A checkweigher is selected based on three main parameters: the weight of the product to be checked, the desired weighing accuracy, and the required production speed. These factors determine the most suitable type of checkweigher for specific production needs and ensure effective quality control without slowing down the flow of the packaging line.

Placement in production lines

Checkweighers can be positioned at various points along the production line depending on requirements. They can be placed after the product has been packaged, for example after a carton machine, to verify that the final weight is correct. Alternatively, they can be positioned before packaging in the case of industrial products with multiple components. In this case, the checkweigher is used to determine if the product is complete with all parts and whether it can be packaged, or if it should be rejected due to non-conformity.

Control and rejection system

The PLC sets the exact weight and acceptable tolerance parameters. The product is transported on a conveyor, weighed in real-time by the checkweigher, and if the weight is correct, it continues to the next processing stages. If the sensor detects an incorrect weight or a weight outside the set tolerances, the product is automatically rejected. Often, products outside tolerance are rejected using a pneumatic device and collected in a dedicated container for possible reprocessing or disposal.

Advantages of checkweighers

Using checkweighers on packaging lines provides numerous operational and quality advantages:
  • Continuous quality control: automatic verification of the weight of each individual product, ensuring consistent compliance with standards
  • Waste reduction: immediate identification of non-compliant products before they proceed along the packaging line
  • Regulatory compliance: precise documentation of weights to meet regulations in the pharmaceutical, food, and industrial sectors

Application areas

Checkweighers are used in various industrial sectors where weight control is critical for product quality. In the pharmaceutical sector, they check the weight of filled bottles, cartons, and packages to ensure correct dosing. In the food sector, they monitor the net weight of packaged products to comply with declared quantity regulations. In the cosmetic and industrial sectors, they ensure that each product contains the correct amount of material.
