Meat and fish firms could benefit from more efficiency

Weighing and packing equipment specialist Ishida Europe has extended its portfolio of kit for poultry, meat and fish packaging with the addition of a novel system that improves yield and efficiency.

The new RobotGrader combines weighing and pick-and-place technologies to grade products of varying weight and pack them to a fixed weight straight into the tray. The system reduces giveaway to less than 1% per pack and can correctly place and orientate the pieces, at speeds of up to 320 pieces a minute.

By comparison, a manual operation can be extremely labour intensive with a single operator only able to pack 30 pieces/min, and where overfill can be anywhere from 5% to up to 20%.

The RobotGrader weighs products on a belt weigher. The information is then fed into the system's sorting algorithms that determine the robot's selection of the pieces. The robot stores the information on a large number of weighed pieces and the system also optimises the number of trays within the reach of each robot, maximising availability from which to create each complete pack. The robot gripper has been designed to grasp each piece firmly but gently and to orientate it correctly in the trays.

Depending on the model, the RobotGrader can handle two, three or four different tray types at the same time. In addition, the system can identify and sort pieces whose weight is unsuitable for tray packing, and direct these to bulk bins (which are integrated into the RobotGrader) as well as freezers, slicers and marinating operations.
