System for placing frozen food items in a fryer

Past issues

●Deep-frying kitchens at food plants posed risks, including heat exhaustion due to the hot, humid work environment and burns caused by hot oil.
●The simplicity of the tasks being performed and the demanding nature of the hot environment posed challenges for worker recruitment.

Solution

Proposing the COBOTTA PRO as a cooking robot that can operate in harsh environments

Placing food items in a deep fryer was automated using the COBOTTA PRO.
(1)    Use a camera to identify frozen items.
(2)     Control the opening and closing of the hand with an electric hand control box.
(3)    Create a robot path generation program using ROS.
(4)    Align items to be fried on the conveyor with an electric hand from RT.
(5)    Automatically place items in the fryer based on picking conditions.
(6)    Eliminate the need for a safety fence by allowing work to be performed alongside human workers in a small space.
(7)    Accommodate the hygienic environment with a food product jacket designed specifically for the COBOTTA PRO that can be attached and removed easily.

*This system was developed by RT Corporation.

The system can operate without a safety fence. It requires little space and can be installed in existing processes.

By using the COBOTTA PRO high-speed collaborative robot, the system can be embedded at locations where human workers performed manual tasks on manufacturing lines at existing plants.
It can be deployed in a small amount of space, without requiring a safety fence.

Recognition and holding of irregularly shaped food items using a proprietary vision system and hand

An AI vision system from RT Corporation is used to recognize irregularly shaped frozen food items piled on food trays, grip them with one of the company’s electric hands, and align them on a conveyor. The hand’s torque value is measured by the electric hand control box, which controls the opening and closing of the hand. In this application, robot operation, image processing, opening and closing of the hand, and conveyor operation are controlled using ROS, allowing the conveyor to operate appropriately as food items are placed in the fryer.


Accommodating hygienic considerations with a jacket designed specifically for the COBOTTA PRO

A jacket* designed specifically for the COBOTTA PRO accommodates the hygienic environment required at a food plant. The jacket protects food items from grease splatter.
*Currently under development.
