The Robotgrader has been developed to grade products of varying weight and pack a fixed weight straight into the package. E.g. filets with a normal distribution from 80-200 g. can be sorted and packed into 600 grams trays, keeping within the EU norm ( which states an average weight of 600 g over the whole batch).

The Robot Grader receives the product weight from a scale or a line scanner. The weight is calculated with previously sorted products to find the best combination within the limits. The calculation becomes more accurate the longer a batch is run since the system collects data from the distribution and know what to expect.

The product is picked ”on the fly” and placed according to the programmed pattern in the package by a robot arm. The packages e.g. trays or thermoformed packs are fed into the machine continuously or with stop-and-go. The system keeps track of the weight placed in all packs and guarantee that the target weight is reached before the pack is transported out for sealing.

The Robot Grader can be fitted with optional units depending on application.
- Weighing module or laser scanner for weight
- Sensors or visionsystem to detect product position and orientation
- In- and out feed of packages
- In feed of products

The Robot Grader can sort and pack 120 products per minute in pattern. The system can also reject products that are outside the limits for size, weight or form.
The system show current status and statistics in the operators colour touch panel. A network connection provides a very convenient way of tracking statistics and production.
All equipment is designed to withstand industrial cleaning for open food production.

By investing in a Robot Grader labour costs can be dramatically reduced and that “give away” to the customer is eliminated.
