High speed with the new delta robot from KUKA for even more productivity

The KUKA Hygienic Oil (HO) portfolio is expanding: the new KR 3 D1200 performs various pick-and-place tasks at previously unattainable speeds. With maximum precision, it now moves up to 6 kg of food, medicine or electronic parts.

Although the KR 3 D1200 has a rated payload of 3 kg, it is designed for loads of up to 6 kg. This makes it one of the strongest delta robots on the market. The small footprint with a diameter of 350 millimeters makes ceiling mounting space-saving and efficient. The robot has a reach of 1,200 millimeters and a vertical working range of 350 millimeters. With a position repeatability of +/- 0.1 millimeters and an angular repeatability of +/- 0.2°, the KR 3 D1200 works very precisely.

The new KR DELTA impresses with unprecedented speed: in the small adept cycle and with a load of one kg, the cycle time is less than 0.32 seconds. To avoid downtimes, the KR DELTA has been designed to be particularly low-maintenance. Encapsulated gears with lifetime lubrication and self-lubricating ball joints help to ensure that the KUKA robot can always perform. The fact that it is made mainly of carbon fiber makes it particularly light and robust. As a result, it impresses with low costs for care and maintenance and maximum productivity.

When handling foodstuffs or pharmaceuticals, the new KR 3 D1200 displays further strengths: It contains food-safe H1 lubricants as standard, which qualifies it for handling foodstuffs in secondary applications. In particular, dry, packaged products such as chocolate, bread or sweets are in good hands with it. For direct contact with raw foods, i.e. the primary sector of this industry, the "older brother", the delta robot KR 3 D1200 HM (Hygienic Machine), launched in 2021, is suitable. Even under the most sensitive conditions, such as those encountered in the raw processing of meat or cheese, the KR DELTA in the HM version promises excellent hygiene.

A combination of the two KR DELTA variants can bring many companies in the food industry a significant step forward. Compared to the KR 3 D1200 HM with its stainless steel body, the new delta robot, made mainly of carbon fiber, is considerably lighter and thus also about a third faster. It impresses with a larger cylindrical work envelope and a lower price.

Anyone who uses several KR 3 D1200 robots on a conveyor belt will want to coordinate their movements optimally. This can be achieved with the aid of three KUKA software products: KUKA. ConveyorTech keeps the movement of the conveyor belts synchronized. KUKA.VisionTech, with its integrated camera in an IP67 housing, detects the goods and facilitates quality control. KUKA.PickControl interlocks the pick-and-place movements of various robots and enables more productive packing and packaging. The interaction of these three software solutions makes automated work as uncomplicated and convenient as possible.
