Checkweigher Solutions of VISIOTT

Consumers want the product they buy to be complete and in the amount declared on the package. They classify manufacturers that meet these requirements as reliable and high quality. Checkweigher systems measure the weights of products in real-time during the manufacturing process. With Checkweigher systems, you can be sure that you produce your product with the right weight and complete.

You can use these systems in many industries, especially food and medicine, to ensure quality control in the production process. Also, you can integrate them into production at very high speeds. VISIOTT’s Checkweigher solutions are innovative solutions designed to meet the production requirements of all industries.

These systems can work integrated with traceable production processes. Besides, they are enormous data sources for measuring line efficiency and accuracy.

What can you do with Checkweigher?

  • During automatic packaging, you can measure the weight of your products. Also, you can remove products manufactured outside the target weight from the production line.
  • You can minimize weight discrepancy by sending commands to the filling unit (feedback/tendency control) during the packaging of inhomogeneous products.
  • You can use it to determine if there are missing products in the package of products consisting of several parts. The simplest and most understandable example would be a liquid form medicine box consisting of a bottle, prospectus, and spoon.

How does Checkweigher work?

A conventional checkweigher consists of input, measurement, and output conveyors. A load cell placed under the measuring conveyor detects weight changes when the conveyor belt is running. Then, it measures the weight of the product passing through it with a certain precision using special mathematical functions. This weight information is processed in the internal automation system. Finally, it decides the acceptance or rejection status of the product.

Implementation of Checkweigher in Pharmaceutical Industry

There are many components in a carton. Even in the simplest carton, there are two components, the drug (in solid, liquid, or semi-solid form) and the prospectus. In different drug implementations, there are also spoons, syringes, pipettes, etc. in the carton for proper dosing. The regulation of many legislators determines the complete components of the drug that the patient will use. For this reason, the drug manufacturer has to undertake that a carton is manufactured completely. Checkweigher solutions control the weight of the smallest component in the carton, ensuring that it is complete.

Let’s take an example of a 25g drug consisting of a carton, a blister, and a prospectus
to better understand the topic. Let’s assume that the carton is 8g, the blister is 15g, and the prospectus is 2g. In this case, the weight of the carton, which is complete for us, should be between 24 -26 g. With this system, we can check whether each product passing through the production line is in the expected weight range and we can separate those that are out of range from the line. In this way, we make sure that each carton produced is complete.

VISIOTT’s Checkweigher systems measure the weight of products from 5g to 1000g with a precision of 0.1 g at a speed of 300 cartons/minute.

Implementation of Checkweigher in Food Industry

Weight for food products is a commercial quantity. Every consumer expects the weight of the product they buy and pay for in return to be accurate. For this reason, food manufacturers use checkweigher systems to maintain brand reliability and make packaging in accordance with regulations. The food industry uses these systems for two main purposes.

  • Checking the weight of products, where each package must contain an equal amount of food, and sending feedback/tendency commands to the packaging machine.
  • Printing a weigh-price information label to products where each package does not contain an equal amount of food.

In the first use, it measures the weight of each produced package and sends feedback/tendency commands to the packaging machine according to the production requirements. Then it rejects the incomplete cartons from the production line and separates them into waste. Because the regulations on packaged food products precisely determine how much is missing or how much more each package may be than the committed weight.

In the second use, it prints a weigh-price label on products such as meat, fish, and chicken that come out of the production line and whose weight cannot be determined during production. These products are usually presented to the consumer in carrier packages such as trays and bags.

Clearly stating the weight, expiration date and kg price of the product on the packaging of the products is a necessity due to regulations and commercial habits.

VISIOTT’s Checkweigher systems enable many industries, especially pharmaceutical and food, to perform weight control along the production line. For more detailed information, please contact our technical team.
