A collaborative weighing system

Past issues

●Weighing process during food production, a dedicated machine must often be installed or work must be manually done by workers, making it difficult to meet cost requirements or ensure sufficient space and personnel.
●It is difficult to automate tasks involving gripping or placing food ingredients of irregular shapes.
●It is difficult to introduce cooperative measurement with a robot because it would not satisfy internal standards for safety or speed.

Solution

COBOTTA PRO and a human worker can share the work of weighing food ingredients on a combination weighing machine.

COBOTTA PRO can replace the work of one worker in the weighing process, which used to be done by two workers facing each other, reduces manpower.
1. The worker places the container on the single head scale.
2. The worker places the food on the weighing plates.
3. The weighing machine identifies which combination of plates will add up to the specified amount of food.
4. The robot places the combined ingredients (instructed by the scale) in the container.
5. Once the robot has placed the specified amount of ingredients, the worker collects the container and replaces it with a new container.
6. The highly sensitive touch-sensing soft cover, made from silicon, ensures safety and increases speed during cooperative work.

Divide food ingredient weighing processes between workers and robots to reduce manpower.

Weighing food ingredients on the multihead scale once required the work of two workers. COBOTTA PRO replaces one of those workers, reducing manpower.
It can work safely beside workers without any need to install a safety fence, even in food production plants with limited space.

The soft hand and 3D camera ensure that even difficult food ingredients of irregular shapes can be gripped

The soft hand securely holds food ingredients that would otherwise easily collapse when using a conveyor or feeder.
The system accurately recognizes where to grip food ingredients by obtaining positional data from the scale and utilizing a 3D camera.
*The 3D camera is installed inside the end effector touch-sensing soft cover.


COBOTTA PRO operates in a wide range of site conditions.

ROS 2 is used to control and monitor robot operation, image processing, and combined weighing, allowing the robot to operate in a way that suits site conditions.
If the robot is moving to collect a food ingredient from the weighing scale but a worker picks the same ingredient from the scale, the robot changes its target and approaches a different weighing scale.

The touch-sensing soft cover* further increases productivity and safety. *optional

The soft cover is capable of detecting touch at a high level of sensitivity. This can help to increase speed during operation when working with a worker, further increasing productivity. The cover can be attached near the hand, where the robot is most likely to make contact with a worker. With the soft cover attached, the robot can operate at a maximum speed of 2,000 mm/s.
