Robotic Destrapper (RCU)
The RCU automates the cutting and removal of steel and PET strap, reducing operator involvement in the processing of metal coils. Its intuitive design coupled with a multi-axial robot arm allows for processing different coil sizes and strap configurations, making it ideal for a wide range of production facilities.
Strap Cutting Process
- Strap placement identification
As the coil is rotated the robot scans to detect the end-lap, once detected rotation continues until the end-lap falls between the 5 - 7 o'clock position. - Cutting and removal
The powerful gripper units hold the strap in place, while the cutter cuts and removes the strap from the coil. - Compaction
The gripper unit places the strap into the folding and rolling unit to pack the strap into a small, easily handled bundle. - Disposal
The unit places the processed strap bundles into a designated waste container on the machine.
Options
- Fixed machine version or indexing model
- Coil handling rotation blocker rollers
- Large or small waste strap bin
- Machine safety guarding package
- Other PLC Control systems
The waste is rolled up by the machine after cutting and disposed in a waste container behind the RCU.
