Robots for feeding machine
  • Loading and unloading of machines in the machining operations
  • Removal from injection molding machines
  • Loading and unloading of injection molding machines for overmould parts
  • Loading and unloading of testing and assembly facilities, etc.
  • More flexibility
  • Large range
  • Space-saving
  • Short cycle times
  • Fast amortization
  • Increase in productivity
  • Robot tasks during the processing time of the machine adopt additional (z. B. palletizing, testing, etc.)


A KUKA robot with console version for 16 kg load capacity was used for the removal of injection moulded parts. The design of a shelf offer on a machine mounted over conventional designs a larger working space to a greater depth, as reduced overall. An advantage of the looks especially during loading and unloading machines noticeable. The shorter lifting distances and longer reach due to the low base frame cycle times in machine.


The robot places the waste parts on the slide. Waste parts are defined as parts whose cycle time has been exceeded and stretch parts that are signaled by the injection moulding machine as not fine. Detection happens at start of production.

After completion of the injection moulding injection moulding machine and the robot removes opens with suction or jaw gripper parts. Once the robot is back in position above the injection moulding machine, the next operation is started. In the meantime the robot places IO parts on the conveyor belt or deposits not IO parts on the slide. The robot then moves in its position on the injection moulding machine and waits for the next part removal. A direct deposition of the parts in a tester or a carrying case is also possible.


The robot places the IO parts on the conveyor belt from each as desired.

Two parts or four parts next to each other or even in rotated positions to save space. The conveyor belt clocks automatically to the component width of a new part. The component width is stored in a table with the data type. After a number of parts, an intermediate gap is automatically generated, so that the operator gets signaled the start of the next packaging unit.

  1. Switchover manual or automatic
  2. Start robot
  3. Increasing the speed of the robot at max. speed
  4. Automatic basic position of the robot
  5. Good part counter resettable
  6. Conditioning emptying until the last packaging unit is ful
  7. Cycle time monitoring of the injection moulding machine. Parts are automatically saved as committee
  8. Scrap counter at the beginning and cycle time monitoring
  9. Good part counter for parts box
  10. Automatic spacing, when number of items is reached on conveyor belt
  11. Flare and honk signal when carton change is imminent acknowledgable at safety fence of conveyor belt
  12. Automatic robot stop, if not acknowledged
  13. Maintenance item request from the injection operator’s side
  14. Online monitoring of the opened injection moulding machine. Means the robot stops immediately its movement in the field of injection moulding machines form, when the signal open form” appears


For handling the robot using a pneumatic gripper with four vacuum circuits and five gripping valves. The robot can be individually equipped with suction or jaw gripper. The use of an automatic tool changing system is also possible.
