Together with the UR partner MS Electronics GmbH, Hailo developed an application with a UR5 cobot. It places up to 1,100 operating instructions per eight-hour shift onto pre-assembled stepladders before they are packed and taken to the warehouse.
The UR5 is positioned directly next to a conveyor belt. As soon as a ladder is approaching on the belt, the cobot picks up a booklet from a magazine with a vacuum gripper. It moves it to a hot glue gun applying adhesive and finally affixes it with light pressure to one of the steps of the ladder. Other ladder models are equipped by the UR5 with accessory cartons which are clamped to the ladders.
UR10 and UR10e Used for Handling Sheet Metal Cylinders
Due to the smooth implementation of the UR5 and the rapid amortization of the acquisition costs, the cobot paid itself back in less than a year. Hailo commissioned the development of two additional UR cobot applications in two of its plants manufacturing waste bins. At the plants, one UR10 and one UR10e each handle painted sheet metal cylinders. The two cobots pick up the blanks with a double gripper specially designed for Hailo. They place them in die-cutting machines where holes are stamped into the cylinders. The implementation of the two applications was challenging: "We had to coordinate the feeding of several die-cutting machines and make sure that the painting of the sheet metal parts was not damaged during handling," explains Marc Straußfeld, owner and managing director of MS Electronics.
The decision in favor of collaborative robotics has paid off for Hailo in every respect. Instead of laboriously inserting the sheet metal bodies into the die-cutting machines by hand, as was the case in the past, the employees today just have to ensure sufficient stock of parts and monitor the production process. They can take on more demanding tasks in the final assembly or other departments. "At Hailo, the robots from UR are now a natural part of the team," summarizes production manager Schmidt. "Thanks to their high repeat accuracy, we maintain our high product standards and the trust in the Hailo brand - because we make no compromises in quality and safety."
