Korean Air Flight Centre at the cutting edge

Faster and more reliable service for airlines

Airport kitchens have to serve departing flights under great time pressure. Besides handling food, drinks, equipment and goods for sale, catering carts provide kitchens with their own logistic challenge. After returning from arriving flights, catering carts must always be emptied, washed, stored and refilled before being delivered to departing flights again. The Swisslog Group companies Cimcorp and Schierholz have jointly supplied Korean Air's new airport flight kitchen at Incheon with an automated catering cart transportation and buffer system.

 

 

 

 

 

 

 


Korean Air has built an airport kitchen at Seoul's new international Incheon airport, where catering cart handling and buffering is completely automated. Swisslog Groupís overhead conveyor supplier Louis Schierholz GmbH of Germany had already supplied a number of catering facilities worldwide with transport and buffer systems using conventional technology. Now, Cimcorp and Schierholz have jointly developed and implemented a new concept for the transportation and buffering of catering carts using an electric monorail system (EMS) and a wide span gantry robot (GR).

Hygiene and speed guaranteed

The core of the buffer system is a large gantry robot supplied by Cimcorp. The catering carts, after having been stripped of waste and washed, are stored on hangers in the robot's working area until they are needed again.

The catering carts arrive in the working area from the cart wash on hangers moving along the EMS supplied by Schierholz. The robot picks the hangers and moves them to the buffer for storage from where they are picked and unloaded according to the orders. A single order always consists of all the catering carts needed for one flight. Once the order is received, the robot picks the hangers from the buffer to meet the order and moves them to the unloading station. From there, the hangers again travel along the Schierholz EMS to different destinations for refilling. Catering carts from various airlines are stored in the buffer and, depending on the type of cart, one hanger can hold from 2 to 4 carts. The capacity of the buffer totals 450 hangers. In one hour 70 hangers can be moved in and 70 hangers can be moved out of the buffer. The catering facility operates 18 hours per day and 351 days per year.

Since the catering carts are stored in hangers under the gantry robot, no fixed structures are needed on the floor, which would hinder cleaning. The floor area can easily be cleared and washed whenever required. Another advantage of the overhead structures is that the retrieval of the catering carts needed from the buffer happens quickly. The robot gripper, having direct access, is able to pick hangers from anywhere in the robot's working area within seconds.

 

 

 

 

 

 

 

 

 


Korean Air eagerly grasped the opportunity to adapt the latest technology for their airport kitchen. The concept developed by Cimcorp and Schierholz is unique in the industry.

Space-saving

Despite its extremely wide span, the gantry robot as the heart of the buffer reduces the buffer space requirements considerably compared with conventional solutions. The hangers with the catering carts can be stored in two layers in the robot's working area. The robot is equipped with an OPS-Box warehouse management system, which controls the stock under the gantry robot according to the product editor and the orders coming from the upper-level software. In this way, trouble-free and reliable delivery of catering carts is guaranteed. The software incorporates a storage optimization feature, which facilitates effective utilization of the available space.

Kwak, familiarize themselves with the catering cart buffer, which is ready for commissioning. Mr. Kwak appreciates the excellent hygiene, speed and reliability provided by the gantry robot.
