Máquina de embalagem horizontal com filme stretch para objetos estreitos

Sumário executivo A horizontal stretch wrapping machine for narrow objects carries tubes and profiles on a roller conveyor through an orbital ring, laying stretch film in a spiral as the piece passes. A top press arm holds light pieces down against film tension, so the section stays on the rollers and the overlap stays even. This guide covers the working cycle, ring sizing, turns-per-piece calculation and the settings we confirm per piece.

O que a máquina faz

An orbital stretch wrapper conveys long workpieces horizontally through a rotating ring and lays a continuous, overlapped spiral film shell around them without manual handling.

Passo Machine Action and Process Control
Avanço The roller conveyor advances the piece into the wrapping station; a photocell detects it and signals the PLC [manufacturer rating].
Segurar The top press arm clamps the piece down, keeping it centered and steady.
Embrulho The ring turns and lays stretch film around the leading edge.
Spiral advance Conveyor and ring speeds run at a set ratio, giving an even spiral overlap along the full length.
Saída The film is cut, the top press releases, and the wrapped piece leaves on the outfeed rollers.

For our standard narrow-bundle orbital line (E400 series), the machine accepts cross-sectional bundle outer diameters from 100 mm to 400 mm, handling lengths greater than 1,200 mm and bundle weights from 15 kg up to 100 kg [manufacturer rating].

Pieces below that range go to small-ring wrappers (package OD 50–200 mm [manufacturer rating]); wide panels 300–1,400 mm wide need wide-body orbital units instead [manufacturer rating].

Por que objetos estreitos precisam de uma prensa superior?

Elongated profiles with narrow cross-sections present specific handling challenges during high-speed packaging:

  • Levantamento de peças leves. A tensão do filme pode levantar uma tira estreita dos rolos.
  • Imprensa de primeira. The arm holds the piece down while it wraps; narrow-line machines carry two press-down devices [manufacturer rating].
  • Espiral uniforme. Steady travel gives a constant advance per ring turn and an even overlap.
  • Superfície limpa. Film keeps handling scratches and dust off the finished faces.

Voltas por peça

The exact number of ring rotations required per product depends on total piece length, film web width, and target overlap percentage.

Exemplo prático (ilustrativo).

item Valor
Comprimento da peça (ilustrativo) 6,000 mm
Largura do filme (ilustrativa) 100 mm
Sobreposição (ilustrativa) 50%
Avanço por turno, 100 × 0.5 50 mm
Rotações por peça, 6,000 ÷ 50 120

In production, spiral overlap is adjustable between 10% and 90% [manufacturer rating]; the setting follows the protection the piece needs.

O que definimos por peça

Each production batch requires aligning mechanical envelopes and drive speeds to match workpiece physical dimensions:

Configuração Machine Parameter / Adjustment Base Standard Narrow-Line Rating [manufacturer rating]
Tamanho do anel Product cross-section (outer envelope) Bundle OD 100–400 mm (E400 line)
Imprensa superior Vertical stroke & pneumatic regulator Dual press-down unit for piece height clamping
sobreposição Conveyor linear speed vs. ring rotation ratio Overlap adjustable 10%–90%; ring speed 20–90 r/min
Transportador Infeed/outfeed bed length and weight limits 2,000 mm powered in/out conveyors; speed 6–12 m/min

Conveyor feed (6–12 m/min), wrapping speed (5–25 m/min) and ring rotation (20–90 r/min) are inverter-adjustable [manufacturer rating].

Wide surface work — doors, MDF boards and sandwich panels 300–1,400 mm wide — goes to dedicated wide-platform wrappers (10–60 r/min, about 4.5 kW) rather than narrow-frame machines [manufacturer rating].

Lista de verificação de seleção

Before ordering or integrating an orbital wrapper into an automated extrusion or finishing line, verify the following mechanical factors:

  • Seção e comprimento da peça.
  • Peso unitário.
  • Largura e sobreposição do filme.
  • Peças por hora.
  • Comprimento de entrada e saída.
  • Peças individuais ou em pacote.

Segurança (Safety)

Rotating rings and moving clamps are the main hazards:

  • Mantenha-se afastado das estações em movimento.
  • Permaneça fora da cerca enquanto a linha estiver correndo.
  • Bloqueie o acesso antes de desobstruir um bloqueio.
  • For CE markets, the machine is designed to ISO 12100:2010 and EN 415-10:2014, the safety requirements for packaging machines.

Perguntas frequentes sobre engenharia

P: Por que uma prensa superior? R: Ela impede que partes leves do filme se levantem sob a tensão da película.

Q: How many turns per piece? A: 120 turns for a 6 m piece in the worked example (100 mm film at 50% overlap, 50 mm advance per turn).

Q: What pieces suit it? A: Tubes, profiles and other narrow objects; narrow-bundle lines take bundle ODs of 100–400 mm [manufacturer rating], with small-ring units below that and wide-body machines above.

P: A peça se move? R: Sim, ela se desloca sobre a esteira de rolos através do anel.

Q: Can it wrap bundles? A: Yes, within the ring size; press-down devices hold the bundle geometry through the cycle [manufacturer rating].

P: Quais normas se aplicam? R: Para os mercados da CE, ISO 12100 e EN 415-10.
