This application required unwinding a roll of polyester lamination film and cutting to length; eliminating static through the process.
We designed a complete system which included a motorized unwind with dancer, a static ionizer, and a cut-to-length knife assembly.
- The roll of material is loaded on to a cantilever design motorized unwind.
- From the unwind shaft, the material goes over idler rollers and a dancer which unwinds the material based on demand.
- The material travels past an edge guide system. An optic sensor monitors the position of the web and positions the unwind to maintain the edge position.
- A servo motor actuator is used to position the unwind.
- The material travels through a dancer accumulator and past an eye registration system into the drive roll station.
- A static ionizer is placed in between the nip rollers and the knife assembly.
- After leaving the drive roller assembly, the material is fed through the guillotine knife assembly and pauses while a robot grips the material. Once the robot grips the material, the guillotine is signaled to make the cut.
- Once the material is removed, the next piece indexes into position and waits for the robot.
- The entire assembly is mounted onto 2 baseplates.
- The unit requires 220VAC 3-Phase and 80psi compressed air.
