  Part 1: Mechanical Adjustments – Pre-Setup Preparation

  Loosen the pressure plate and slide it forward. Remove the internal erector module to facilitate access during setup. Take a sample blank carton and manually form it once for reference.

  1. Adjust conveyor belt width: Turn the belt-width adjustment handwheel until the discharge width matches the carton width.
  2. Set pressure plate height: Rotate the height-adjustment crank to position the pressure plate approximately 2–3 mm above the carton height. Then return the plate to its operating position and lock it securely.
  3. Adjust magazine (stacker) width: Turn the magazine-width crank so that the slot width closely matches the unfolded (flat) carton width—just enough to allow smooth, gravity-fed feeding without jamming.
  4. Set magazine height: Using the bottom edge of the backstop as a reference, turn the magazine-height adjustment crank to set the correct vertical position.
  5. Align pre-fold guide blocks: Loosen the locking handle, adjust the conical alignment blocks so they line up precisely with the carton’s score lines, then re-tighten the lock.
  6. Level suction head: Turn the suction-head adjustment knob until the suction cup plane is perfectly parallel to the conveyor belt surface.
  7. Align pusher rod: Rotate the pusher-rod adjustment knob so the main push bar aligns exactly with the carton’s fold line.
  8. Load test carton: Place an unfolded carton into the magazine and lower the feed assist plate. Mechanical preparation is now complete.

  Part 2: Manual Test Run – Step-by-Step Erection Sequence

  Switch the machine to Manual Mode and perform the following steps:

  1. “Pick Box Forward”: Move the suction head close to the large panel of the carton—but ensure it does not extend beyond the fold line.
  2. “Activate Suction”: Manually push the carton slightly forward to confirm the suction cups securely grip it.
  3. “Pick Box Forward” (again): Observe the pusher rod position. It must be parallel to the carton face. If not, readjust using the pusher-rod crank.
  4. “Fold Front/Back Flaps”: Trigger the mechanism to fold the leading and trailing flaps.
  5. “Fold Side Flaps”: Watch both side flaps carefully—the folding blades should be centered exactly between them. If misaligned, fine-tune the suction head position using the pick-box adjustment knob.
  6. “Push Box Forward”: Advance the fully formed carton out of the machine. If it exits smoothly, the setup is successful.
  7. Reset: Press the emergency stop button to clear the cycle and reset the system.
  8. Reinstall erector module: Loosen the pressure plate again, carefully slide the internal erector module back into place using the shaft ends, then re-lock the pressure plate.

  TIP: After successful calibration, mark all scale indicators with a permanent marker or label for quick future changeovers.

  Finally, switch to Auto Mode and press Start—the case erector will now automatically form cartons.
