Máquina envolvedora de palets: funcionamiento y aplicaciones

> A turntable pallet wrapping machine turns the loaded pallet while a film carriage rides up and down a mast, laying pre-stretched film round the load. Our A200 takes loads up to 1,800 mm high within a 2,000 mm turning diameter, pre-stretches the film at 250% and wraps 20–40 loads an hour. The operator places the pallet by forklift, ties on the film and presses start; the PLC does the rest.

On this turntable wrapper the load turns on an orange turntable beside a dark mast. A red photocell spot on the load marks where the carriage senses the load height, and the control panel with display and buttons sits on the mast. At the base, the film is gathered into a tight rope that ties the load to the pallet.

Operación paso a paso

1. **Load.** A forklift sets the pallet on the turntable from the front or rear. The turntable is low, so no ramp is needed for a forklift.
2. **Tie on.** The operator threads the film through the carriage (W threading pattern) and ties the film end to the pallet.
3. **Start.** The turntable starts softly. A photocell on the carriage finds the top of the load.
4. **Wrap.** The carriage lays the bottom, middle and top layers set on the panel, then returns to the bottom.
5. **Finish.** The turntable stops at its start position, the operator cuts the film, and the forklift takes the pallet away.

Wrap settings that matter

- **Bottom winds** lock the load to the pallet. Gathering the film into a rope at the base, as on the load above, adds strength where the load meets the deck.
- **Top winds** hold the top layer, and a re-wrap or overwrap adds a band where the load is weakest.
- **Overlap** is set by carriage speed against turntable speed. Both are adjustable, the turntable by frequency converter.
- **Pre-stretch** is set at 250%, with 100% to 300% as options. More pre-stretch gives more metres of film per roll. The force the film puts on the load is set separately by the variable force control between carriage and load, so light or fragile loads are not crushed.

Each layer can be set from 0 to 99 winds, and independent top, middle and bottom counters show what was applied.

Aplicaciones por industria

| Industry | Typical load | What the wrap does |
| :--- | :--- | :--- |
| Food and beverage | Cartons, bottles, cans | Keeps layers square, stops shifting in transit |
| Chemical | Bags, drums, pails | Holds loose bags, keeps dust and rain off |
| Building materials | Tiles, bricks, panels | Ties a heavy, dense load to the pallet |
| Household appliances | Large boxed units | Protects boxes from scuffing and moisture |
| Paper | Reams, rolls | Keeps damp air off |
| Electronics | Cartons | Shows tampering and keeps dust off |

| Max load weight | 1,800 kg standard; 2,000 kg custom |
| Turntable speed | 13 r/min, adjustable |
| Output | 20–40 loads per hour |
| Film | LLDPE 0.025 mm, 500 mm wide, 76 mm core, roll OD 150–250 mm |
| Pre-stretch | 250% (optional 100%–300%) |
| Power supply | 220 V 1 Ph 50 Hz standard, other voltages to order |
| Machine weight | 650 kg |

Worked example: one pallet

Take a pallet of 1,200 × 1,000 × 1,600 mm and 900 kg, with 500 mm film at 50% overlap and 250% pre-stretch, 3 bottom and 3 top winds.

| Paso | Cálculo | Resultado |
| :--- | :--- | :--- |
| Turning diameter | √(1.2² + 1.0²) | 1.56 m (inside 2,000 mm) |
| Rise per turn | 500 × (1 − 50%) | 250 mm |
| Turns up | 1,600 ÷ 250 = 6.4 | 7 up, 7 down |
| Total turns | 14 + 3 + 3 | 20 |
| Wrapping time | 20 ÷ 13 r/min | 1.54 min, about 92 s |
| Film on the load | 20 × 4.4 m (perimeter 4,400 mm) | about 88 m |
| Film off the roll | 88 ÷ 3.5 | about 25 m |
| Film mass | 0.000025 × 0.5 × 25 × 920 kg/m³ | about 0.29 kg |
| Pallets per 1,500 m roll | 1,500 ÷ 25 | about 60 |

**Result.** The pallet fits the A200 by turning diameter, height and weight. The 20–40 loads an hour range means 3,600 ÷ 40 = 90 s to 3,600 ÷ 20 = 180 s per load. With 92 s of wrapping plus 45–60 s for forklift handling, tie-on and cut (illustrative), the cycle is 137–152 s, about 24–26 loads an hour. The top of the range needs fewer winds and smaller loads.

Lista de verificación de selección

1. Largest and smallest load size, and maximum height.
2. Heaviest load.
3. Cargas por hora.
4. Load type: stable cartons, loose bags or fragile goods.
5. Film grade and pre-stretch target.
6. Power supply voltage.

Seguridad: EN 415-6 e ISO 12100

Pallet wrapping machines are governed by EN 415-6, with the risk assessment to ISO 12100:2010. The turning load and the moving carriage are the hazards. The A200 has a red mushroom-head emergency stop, a lockable electrical disconnect and a European-approved electrical enclosure, and the turntable starts and stops softly so tall loads do not tip.

Preguntas frecuentes sobre ingeniería

Q: How tall a load can the A200 wrap?
A: Hasta 1,800 mm.

Q: How heavy?
A: 1,800 kg as standard, 2,000 kg on a custom build.

Q: How much film does a pallet use?
A: About 25 m off the roll for the 1,600 mm pallet in the example, about 0.29 kg.

Q: Does it need three-phase power?
A: No. The standard supply is 220 V single phase, 50 Hz; other voltages can be supplied.
