Robots for food and beverage plants

Cases onto pallets at the end of the line is the most common first robot in a food plant, and the end of line is also where the labor turnover is worst. The washdown zone is a different conversation, and it is stated here first.

Free, about two minutes, no phone number. You get an honest no when a robot is the wrong answer.

Who this is for

You run one or more packaging lines with people stacking cases, bags or trays at the end, two or three shifts, and turnover that never stops. Some of your floor is a washdown zone with hygienic design rules; most of the end of line is not.

What automates first here

• Palletizing: the first robot in most plants: cases at 5 to 60 pounds, one or two pallet positions, a lift axis for tall stacks
• Palletizing bags and sacks: bag grippers and pattern building for ingredients and pet food
• Mixed case palletizing: where the software matters more than the arm
• Depalletizing incoming pallets: the mirror job at receiving
• Case erecting and packing: upstream of the palletizer, where an arm per line can replace a crew
• Tray and cup denesting: gentle handling at speed
• Floor scrubbing: plant floors are hard floors, and a scrubber runs between shifts

Machines that usually make the shortlist

End-of-line palletizing runs on collaborative arms in the 20 to 35 kg class on lift axes, or on industrial palletizers above those rates; our matrix carries palletizing-capable arms from close to forty makers. Case packing and denesting use delta robots and small arms with gentle grippers. In washdown zones, ask for the arm's IP rating and the food-grade lubricant statement before anything else; many arms in the matrix are not rated for it.

Every machine named on this site is in the published matrix with figures checked against the maker's material and no prices, because a price before an engineer has seen the job is a guess.

What has to be true before anyone quotes

• Case weight, rate at true peak, and the pallet pattern, including how tall the stack goes.
• How cases arrive at the station: a steady conveyor or a person pulling from something less tidy.
• Washdown or not, and the hygienic design rules for that zone.
• One pallet position or two, so the robot keeps working while a full pallet is pulled.
• Line-of-sight and traffic from forklifts and people near the cell.

When a robot is the wrong answer here

• Rates and case weights above the collaborative class without room for a guarded industrial cell.
• A washdown zone with no washdown-rated arm in budget.
• Product that changes shape or weight case to case with no pattern.
• An end of line that is really a scheduling problem upstream.

Common questions

How fast can a cobot palletizer really go?

Six to thirteen cases a minute is the range makers quote, and the low end is what most plants see with one case per pick near people. Two cases per pick and a fenced industrial cell move the number, at a cost. Ask for the rate at your case weight and pattern, not the brochure rate.

Can a robot work in my washdown area?

Some can, if they carry the IP rating and food-grade lubrication for the zone. Most collaborative arms cannot. The honest quote names the rating on the specific model and the parts of the cell that still cannot be hosed down.

Will it replace my whole end-of-line crew?

It replaces the stacking. Someone still swaps pallets, handles the rejects, and watches the line. The casebook entries from wineries and an egg packer show what stays human.
