Question 1

What is a robotic case erector?

Accepted Answer

An automated machine that draws flat corrugated blanks, forms them into open cases, and seals the base, synchronised to the downstream case packer's loading rate.

Question 2

What is the difference between a case erector and a case packer?

Accepted Answer

A case erector forms the corrugated case from a flat blank and seals the base. A case packer loads products into the formed case. They are sequential stages in the same packaging system.

Question 3

Adhesive or tape sealing, which is better?

Accepted Answer

Hot-melt adhesive for most production applications, faster cycle, stronger seal, consistent geometry. Tape for applications where cases must be opened cleanly at distribution centre or retail level.

Question 4

Why is a robotic case erector important for OEE?

Accepted Answer

Without it, manual case forming caps the loading station at 4–8 cases/min, far below modern case packers. The erector removes case supply as a speed constraint, allowing the case packer to run at rated capacity.
