The checker is used to control the weight of the material while moving. Combining this device with a variety of printers or detachable systems has many applications in various industries. These devices, depending on the dimensions and weight of the product, can measure the weight of up to 500 products per minute and produce undesirable products. Today, many of these devices are used in factories to ensure the correct weight of manufactured goods. One common method of using a checkerboard is to weigh the motherboard of the products at the end of the packaging line and at the time of entry. It is a warehouse. In case of operator error or Packer carton, this device determines how many products are in the carton and if the number is more or less, the checker shows that the weight of the carton is not correct and if there is a reflector at the end of the checkerk device. The carton is automatically removed from the line. This device can also act as a weight counter for products. In this way, the weight of the moving product is measured and at the end of the checker line, different stations separate products with defined weights and unload them at a specific location from the production line or conveyor belt installed along the sorter. They usually have 3 consecutive conveyor belts. The first conveyor belt separates the products and transfers them to the second conveyor belt. This conveyor weighs the products and has a similar function to the scales. On the outlet strip, there is a rejector that can remove products that are not the right weight. Applications: Food and Beverage Industries, Pharmaceuticals, Cosmetics, Washing and Chemical Industries, Parts manufacturing, petrochemicals and in general all industries that have packaging. Features: Ability to define tolerance for determining parts outside the weight range with a spacing system with a separation system for lighter and heavier parts than the allowable alarm light for components outside Weight range
