Spraying of parting agent

In the second application, two KR 30 L15s were installed in an inverted position on a linear unit, and a third in upright position on the floor. Here the cycle times of the robots are identical to those of the line. To achieve this, the robots have to operate with high acceleration values. Each of the inverted KR 30 L15s is responsible for two molds. They only spray the upper halves, however, while the lower halves are sprayed manually with the aid of short, light spray guns. In this case, manual spraying is more cost-effective than additional robots, since human operators are essential here regardless. They have to take the parts out of the molds and check whether the latter are clean. In this production island, which does not produce complete carpets, but only insulating foam, Sommer Allibert exchanges the molds frequently. The molds are coded, thus indicating to the robots which path motions are to be executed.

• Two KUKA KR 30 L15 robots mounted in an inverted position
• One floor-mounted KUKA KR 30 L15 robot
• One KUKA KR 15 robot mounted in an inverted position
• Four PC-based KUKA KR C1 robot controllers, including control panels with Windows interface
• Handling device moved by the robot controller
• Plastic covers to protect the robots against fouling
• Robot programming
• Commissioning

• High flexibility
  
  Sommer Allibert is able to program the robots itself by means of the familiar, easy-to-use Windows interface of the control panel. The programs can then be selected quickly and conveniently. The resulting high degree of flexibility saves the user time during the frequent mold changes that are carried out.
  
  
  

• High maneuverability
  
  The robots are highly maneuverable, since unlike parallelogram robots they can also work “overhead”.
  
  
  

• Remarkable radius of action
  
  The robot types used here, the KR 15 and KR 30 L15, have the same carrying capacity. Moreover, the KR 30 L15s are equipped with longer arms and the wrists which were actually designed for the KR 15. This reduces their carrying capacity to a perfectly adequate 15 kg, while as the KR 30 L15 their radius of action is significantly extended. Without this advantage, the application would have been more expensive to implement, and would have required more space.
  
  
  
• Rapid payback
  
  According to a binding agreement, a payback period of two years was stipulated for the robots and their controllers.
