Why Won’t the Carton Lift Properly? How Suction Cup Position and Air Pressure Affect Pickup

2026-03-03

Q: Why does the carton fail to be picked up during the opening process?

A: This usually relates to suction cup position or air pressure. If the suction cup is aligned with holes on the carton, air leakage will occur, reducing suction and making it impossible to lift the carton stably. Low air pressure (below 0.4 MPa) can also cause pickup failure.

Q: How does suction cup position affect carton pickup?
A: The suction cup positions are adjustable. If they align with carton holes during operation, leakage will occur, causing both cups to lose suction and fail to pick up cartons. The key is to avoid carton holes—adjust the suction cup downward or move to another mounting hole.

Q: How does air pressure affect suction performance?
A: Unstable air pressure directly impacts suction. By checking the pressure gauge, if air pressure drops below 0.4 MPa, pickup failure or carton drop may occur. Maintaining stable air pressure prevents these issues.

Q: What are the operational recommendations?

1. Check suction cup position and avoid carton holes.

2. Ensure air pressure is stable and above 0.4 MPa.

3. If pickup is not smooth, adjust suction cups to other mounting holes.
