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.
