Increased movement dynamics due to productivity package
The workpiece may fall out or be ejected! Risk of injury!
Ø
Before starting an older project, check the holding force and
stability of the corresponding gripper and confirm the respec-
tive dialog.
Ø Calculate the suction cup capacity (see "Calculating suction
cup capacities", pg. 4
‐

Ø Adapt the number of suction cups to the gripper.
Ø If the number of suction cups cannot be increased: reduce
the speed of the travel points
(see "Points, editing", pg.
4
‐
96) .
Ø
For magnet gripper: reduce the robot speed (override) to
50%
(see "Determining the reduction of the robot speed",
pg. 4

2. Adjust the parameters to the weight of the workpiece. When
doing this, make sure that the center of gravity of the work-
piece is in the center of the suction cup arrangement.
Calculating suction cup capacities
Condition
■ The geometry of the workpiece is known.
1. Determine the weight of the workpiece.
2. Determine the number of required suction cups using the fol-
lowing table:
Nominal diameter in [mm] Carrying capacity [kg]
30 0.25
40 0.5
50 0.75
60 1
80 1.75
125 4
Suction cup diameter-carrying capacity for productivity pack-
age Tab. 4-7
Example :
A blank weighs 30 kg. Only suction cups with a diameter of
60 mm are available (load-bearing capacity 1 kg).
30 kg: 1 kg = 30.
Thirty suction cups are required.
