Industry 4.0 a Practical Reality
Flexible Production of Fiber Composite Components without Set-up Times
Case Study
Application
Production line for composite components with a
gripper spider of 15 needle grippers
Handling Task
Reliable, automated handling of composite textiles
One product changeovers per day
Each product requires different needle strokes due
to different material thicknesses
Schmalz needle gripper SNG-AE
Schmalz Solution
Needle gripper SNG-AE for handling non-rigid and highly porous materials
(primary textiles)
10 crossed needles offering high holding forces
Needle stroke (max. 3 mm, 10 mm or 20 mm) is freely adjustable using
definable process profiles
Stroke can be adapted for each cycle in any order
Handling of individual layers and stacks with a single gripper
Continuous process monitoring (stroke and energy consumption)
IO-Link interface for bidirectional communication with higher-level Freely adjustable needle stroke
field-bus systems
Customer Benefits
Elimination of setup and downtime during production changeovers
No manual setting and control directly at the gripper and no test runs required
Minimal risk of incorrect settings
Increased flexibility of production lines (small batches)
Error detection during operation and error correction in the planned maintenance

Automatic reparameterization in the case of exchange of separate grippers
Saving Potential Using the Example of a Gripper Spider for Composite Components
The spider in this example is equipped with 15 needle grippers, a production changeover takes around 12
minutes when using conventional needle grippers. This time includes processes, such as stopping the
machine, reparameterizing the components and also tests that are required after the changeover. If the
grippers are changed once a day, the approximated costs for downtime are around EUR 600 for each work-
ing day (EUR 50/minute). If the spider is running 300 days each year, this results in approximated annual
downtime costs of EUR 180,000 when using conventional grippers. With the needle gripper SNG-AE from
Schmalz, set-up times and downtime for this spider can be almost completely eliminated using remote
parameterization via IO-Link.
Saving Potential of
180.000 € per Year
