Requirements
This application required punching a roll of material approximately 4” wide and then rewinding it back onto a core. Precise holes were placed in the material. The cycle rate requirement was approximately 400 punches/minute with a tolerance of +/- .008”
Our Solution
- One of our standard modular components was configured to meet the requirements.
- A fully enclosed frame supported all the assemblies.
- The material was placed onto a motorized unwind that had a dancer roller.
- As the dancer roller lifted or lowered, the motor of the unwind sped up or slowed down.
- From the unwind, it went into a set of ball bearing idler rollers.
- The idler roller assembly guided the material into our servo-driven punch assembly.
- Precision male/female punch and dies were used to get clean cuts, high accuracy and long life.
- After the punch assembly, servo-driven nip rollers indexed the material to the exact location prior to every punch.
- A tray and bucket collected all the punch scrap for easy convenience.
- The operator was able to control the unit from a color touch screen.
- From the touch screen, the operator had the ability to change the index length, motor speeds and velocities, and time dwells for all axes.
- The entire unit was compact in size, fully enclosed and guarded, and required 110V to operate.
