The highest precision and fineness is required when handling highly sensitive glass tubes. For this reason, the machine loading was previously carried out by employees. However, these highly qualified employees can be deployed much more effectively.
For this reason, the company was looking for robots that could perform these highly sensitive tasks. With Universal Robots collaborating robots, the company found the right ones.
“The glasses are extremely sensitive. Even the slightest temperature changes on the tools affect the forming result. Our employees used to load the glass lathes manually. Even short interruptions in the work process naturally caused the machines to cool down again and again. When we first used the collaborating UR robots for this task, we suddenly got top results,” explains Robert Hofmann, Managing Director at Hofmann Glastechnik.
A further challenge in the company is the necessary flexibility. The robots must be able to be quickly assigned to other tasks.
In their regular work, a UR5 and a UR10 robot feed the production components to several PLC-controlled glass lathes. They do this up to eleven hours a day.
The company has developed a mobile device so that they can also be used flexibly at other workplaces. With this device, the robots can easily be assigned to other workplaces and immediately continue with this task.
