Avvolgitrice per pallet per bobine di grosso peso

Sintesi

A pallet wrapping machine for big, heavy coils turns the coil on a reinforced turntable while a film carriage wraps its outside. Our heavy-duty version, the A200B, carries up to 5,000 kg on a 1,650 mm turntable, turns at up to 12 rpm and pre-stretches the film 250%. Below we check a steel coil’s weight against the turntable, show why centring matters, work out the film per coil, and explain when an eye-through coil wrapper is the better machine.

A big coil in a white protective cover sits on the yellow turntable, cradled by two black rollers set into the table surface. The turntable turns slowly, and the film from the carriage on the grey column builds up round the coil. The control box beside the column has a display and a red emergency stop; spare film rolls stand on a rack behind.

Sommario

Why a turntable wrapper for coils

A turntable wrapper covers the outside of the coil against dust and handling marks, at low cost and with simple loading. It does not pass film through the eye, so the bore and the inner edges stay open. For storage indoors or short transport that is often enough. For sea freight, or when the edges must be sealed, use an eye-through wrapper.

Check the coil weight first

For a steel coil: m = π ÷ 4 × (OD² − ID²) × width × 7,850 kg/m³.

Bobina Calcolo Peso On a 5,000 kg turntable
OD 1,200, ID 508, width 600 mm 0.785 × (1.44 m² − 0.258 m²) × 0.6 m × 7,850 kg/m³ 4,370kg si adatta
OD 1,200, ID 508, width 1,000 mm 0.785 × (1.44 m² − 0.258 m²) × 1.0 m × 7,850 kg/m³ 7,280kg troppo pesante

These are illustrative coils. Paper and fibre rolls are far lighter for the same size, so the turntable limit rarely bites for them.

Centring and the cradle

The coil stands eye-to-wall, with its bore horizontal, and would roll without restraint, so the two rollers in the turntable form a cradle that holds it still. The coil must sit with its centre over the turntable axis. An off-centre load swings the turntable bearing out of balance and makes the film tension rise and fall each turn.

Keep the turn speed low for the heaviest coils; soft start and stop limit the shock on the drive. The allowed centring offset and a coated cradle roller for sensitive coil finishes are confirmed at quote.

Check the turning diameter too: the coil’s diagonal in plan must stay inside the 2,000 mm maximum turning diameter. A 1,200 mm coil 600 mm wide has a plan diagonal of √(1,200² + 600²) ≈ 1,342 mm, well inside.

Pellicola per bobina

Take the 1,200 × 600 mm coil standing on its cradle, wrapped up and down with 3 bottom and 3 top winds. At 12 rpm one turn is 5 s, and the carriage climbs 2,900 ÷ 60 ≈ 48 mm/s.

Turntable wrapper or eye-through wrapper?

Bisogno Involucro per giradischi Eye-through coil wrapper
Cover the outside only sì sì
Seal the bore and edges no yes, film passes through the eye
Sea freight, rust protection limitato preferito
peso della bobina up to 5,000 kg on the A200B to the model, confirmed at quote
Cost and floor space minore superiore

Lista di controllo per la selezione

  1. Diametro esterno, diametro interno e larghezza della bobina.
  2. Coil weight and material.
  3. Bobine all'ora.
  4. Outside cover only, or full seal through the eye.
  5. Loading: forklift, crane or coil car.
  6. Alimentazione elettrica.

Sicurezza

We design to EN 415-6 for pallet wrapping machines, with EN ISO 12100:2010 for risk assessment and EN 60204-1 for the electrical equipment. A heavy coil on a turning table stores a lot of energy, so keep people out of the turning zone with perimeter fencing and interlocked access gates. Use the red mushroom emergency stop and the lockable disconnect. Guarding and CE documents are agreed per project.

FAQ di ingegneria

Q: What is the heaviest coil it takes? A: 5,000 kg on the A200B turntable.

Q: Does the film cover the coil eye? A: No. For the eye and edges, use an eye-through wrapper.

Q: How is the coil loaded? A: By forklift or crane onto the cradle; the turntable is only 80 mm high.

Q: Can the machine be moved? A: Yes, it is forklift portable from front and back.

Q: Can it wrap paper or fibre rolls? A: Yes, the same way; check the roll size against the turning diameter.
