APPLICATIONS

CUT TO REGISTER FEED DRIVE SYSTEM

Application Solution: The DeltaPro 11/2 axis controller with a simple OPI-50 keypad/display provides a simple solution for this application. A servomotor is configured to drive the feed rolls and the following I/O's are connected:

• Outputs: Cutter & Punch
• Inputs: Registration sensor, UP/DOWN limits on both cutter and punch

1. The operator loads a fresh spool of material into the machine and enters the cut length and batch count.
2. The operator then presses initialize on the keypad and the servo feeds the material forward and stops at the registration mark.
3. The operator presses start and the feed sequence begins:
   • Turn on the punch and cutter
   • Wait for punch and cutter to be down
   • Turn off punch and cutter
   • Wait for punch and cutter to be up
   • Start servo feed
   • During the feed search for the registration mark
   • Stop at registration mark
   • Repeat
4. The feed sequence continues until the batch count is reached, a fault is detected or the operator manually stops the feed sequence.

• The motion profile is a bell shaped minimum jerk profile to minimize web stretch and feed roller slip.
• A double feed, one for cut and one for punch can be used to change the cut to punch dimension.
• Loss of registration mark warning/shutdown.
• Output from DeltaPro signals run sequence to unwind stand.

• Perforating press
• Cut and seal
• Feed drive
• Progressive die part transfer
