Sintesi

A robot pallet wrapper is a self-propelled wrapping machine. The load stays where it stands, and the machine drives around it while the film carriage runs up and down its mast. It needs no turntable, no fixed position and no forklift move, so it suits heavy, oversized or irregular loads and warehouses with many wrapping spots. Our equivalent solution is configured per load, with speeds and options confirmed at quote.

The red and black machine carries a roll of LLDPE stretch film on its carriage and a control panel with a touch screen, start and stop buttons. The pallet load stands still on the floor while the machine moves around it on small wheels, laying the film in a spiral over the load faces. At the end of the cycle the film is cut and the machine stops, ready for the next load.

Robot wrapper or turntable wrapper?

La Domanda	Robot wrapper	Involucro per giradischi
Does the load move?	no, it stays in place	yes, it turns on the table
Dimensione di carico	set by the floor space around it	set by the turntable diameter
peso del carico	not limited by a table	limited by the turntable rating
Where it wraps	anywhere on a flat floor	at one fixed station
Forklift moves	none to the wrapper	uno dentro, uno fuori
Uscita	lower, one load at a time by hand	higher, can run in a line

Regola. Choose the robot wrapper when loads are too big, too heavy or too unstable to turn, or when they are wrapped in many places. Choose a turntable wrapper for steady, standard pallets at a fixed station.

How a robot wrapper follows the load

The operator places the machine at a corner of the load and ties the film tail to the pallet.
The machine drives around the load at a steady distance from the load faces. Robot wrappers usually steer with a feeler (tracer) wheel that runs against the load; the guidance on our equivalent solution is confirmed at quote.
The film carriage starts at the pallet base to lock the load to the pallet, then climbs the mast while the machine circles, with an optional return down. Bottom, middle and top turns are set on the panel.
At the end of the cycle the machine stops, the film is cut and the operator moves it to the next load.

Because the machine follows the load outline, the same machine wraps a 1,200 × 1,200 mm pallet and a long crate.

Film use and travel distance

Two lengths matter: the film laid on the load and the distance the machine drives.

Film on the load = turns × load perimeter. Driven path = turns × path perimeter.

Ingombro di carico	Perimetro di carico	Film for 12 turns	Path about 0.5 m outside	Driven for 12 turns
1,200 × 1,000 mm	2 × (1.2 + 1.0) = 4.4 m	12 × 4.4 = 53 mt	2 × (2.2 + 2.0) = 8.4 m	12 × 8.4 = 101 mt
2,400 × 1,200 mm	2 × (2.4 + 1.2) = 7.2 m	12 × 7.2 = 86 mt	confirmed on site	confirmed on site

The film on the load is stretched film. The film taken from the roll is shorter: film from the roll = film on the load ÷ (1 + pre-stretch). At an illustrative 200% pre-stretch, 53 ÷ 3 = 18 m per load. The pre-stretch ratio is confirmed at quote.

Risultato. The machine drives about twice the film length for a standard pallet. Cycle time = driven path ÷ travel speed. Travel speed and turns per load are confirmed at quote, so ask for the cycle time on your largest load.

Floor, battery and site checks

Vedi	Perché è importante
Flat, clean floor around the load	the wheels and steering need a smooth path
Free space on all sides	the machine must pass every face without hitting racks or walls
Battery charge per shift	the number of loads per charge is confirmed at quote
Punto di ricarica	the machine is parked and charged between shifts
Altezza di carico	the mast must reach the top of the tallest load

Sicurezza: EN 415-6 e ISO 12100

Pallet wrapping machines are covered by EN 415-6, with the risk assessment to ISO 12100:2010. With a robot wrapper the hazard moves with the machine, so there is no fence. A mobile wrapper therefore needs a safety bumper or sensitive edge that stops it on contact, as well as the emergency stop on the panel. The operator keeps the area clear and the floor around the wrapping spot is marked. Guarding and CE documents are agreed per project.

FAQ di ingegneria

Q: Can it wrap loads that do not fit a turntable? A: Yes. The machine drives around the load, so length, width and weight are not limited by a table.

Q: Does it need to be fixed to the floor? A: No. It moves on wheels and can wrap wherever there is a flat floor and space around the load.

Q: How fast is it? A: Cycle time is the driven path divided by the travel speed. The travel speed is confirmed at quote.

Q: What is the battery life? A: Loads per charge depend on load size and turns, and are confirmed at quote.

Q: Can it wrap round or odd-shaped loads? A: Yes. It follows the load outline, which is why it is chosen for loads of different sizes and shapes.
