알루미늄 프로파일 포장기 및 랩핑 라인: 스테이션 및 속도

개요
An automated aluminum profile packing line integrates sub-bundle strapping, high-speed orbital spiral wrapping, automated collation, and master bundle master-wrapping into a continuous flow. The inline sub-bundle wrapping station handles cross-sections from 외경 100mm ~ 300mm and lengths exceeding 1,000 mm at line speeds up to 12m/분. Because the orbital wrapper acts as the primary pacing bottleneck between upstream extrusion outputs and downstream master bundling, overall line throughput is sized directly around this station’s cycle and cycle-reset envelope.

포장 라인의 스테이션

Plant layout, extrusion press capacity and profile specifications dictate the line topology. A standard automated packaging line integrates seven core stations:

역 계단 시스템 기능 Station Description
01 Sub-bundle binding 4 binding stations securing loose extrusions
02 Sub-bundle transfer Transfer arms bridging binding tables to the wrapper
03 Sub-bundle orbital wrapping High-speed continuous stretch/paper wrapper
04 서브번들 수집 및 정렬 Buffer table aligning wrapped sub-bundles
05 Master bundle assembly Multi-fork gantry assembling final bundle matrices
06 Master bundle wrapping Orbital wrapper for shipment-ready master packs
07 Bundle outfeed Motorized discharge roller tables

The line wraps with kraft paper or LLDPE stretch film. A 6-fork transfer mechanism lifts an entire layer of sub-bundles onto a staging roller bed, repeating the cycle until the planned bundle matrix is complete.

서브 번들 래퍼의 작동 방식

The sub-bundle advances on powered infeed rollers into the rotating orbital ring. The reel of paper or film rides a circular track and applies a helical wrap while the conveyor moves the bundle forward.

[Infeed Conveyor] ---> [Centering Rollers] ---> [Hold-Down Unit] ---> [Orbital Ring] ---> [Outfeed Conveyor]
                                                        │                     │
                                                        ▼                     ▼
                                                 (Anti-Torsion)       (Continuous Spiral)
  1. 중심: Conical vertical rollers centre incoming profiles on the pass-line.
  2. 누르고 있기: Pneumatic rollers clamp the extrusions to the bed, preventing twist, splay and vibration at high ring speed.
  3. 사이클 제어: Photocells detect the bundle ends and trigger film feed, wrapping, clamping and cutting via the PLC.

Bundle Window: Physical and Dimensional Envelope

The sub-bundle wrapper handles standard mill-finish, powder-coated and anodized extrusions:

매개 변수 Specification Window 엔지니어링 노트
Bundle Cross-Section (OD) 100mm에서 300mm Diagonal must clear the inner ring
번들 길이 1,000mm ~ 6,000mm 이상 Extension conveyors sized per layout
Sub-Bundle Weight 15kg에서 100kg Within standard conveyor loading
Wrapper Conveyors 2,000 mm infeed / 2,000 mm outfeed 기본 면적
선형 컨베이어 속도 6m/분 ~ 12m/분 VFD 제어
링 회전 속도 20RPM ~ 90RPM Inverter driven
Nominal Wrap Output 5m/분 ~ 15m/분 Governed by overlap and travel
Spiral Overlap Range 10의 % 90 %로 Adjustable via VFD and ring speed

예시: six profiles at 1.5 kg/m and 6 m long weigh 54 kg, within the 15–100 kg rating. Conveyor speed is limited to 12m/분 to prevent profile slippage on the roller surfaces.

Which Station Sets the Line Pace?

With four upstream binding positions feeding one sub-bundle wrapper, the wrapper is the line’s critical path.

The pure wrapping cycle time per 6-meter bundle scales with conveyor feed rate:

선형 래핑 속도 Pure Wrap Cycle (6 m bundle) 이론적인 최대 처리량
12m/분 30 초 120개 묶음/시간
5m/분 72 초 50개 묶음/시간

Cycle time allowances: these figures cover continuous wrapping travel only. Transfer, film cutting and roll changeover add time.

For a master bundle of 12 sub-bundles, wrapping travel is 12 × 30 s = 360 s (6 min). This window lets the downstream master bundling station gather, stack and wrap without halting extrusion outfeed.

End Taping and Material Management

An integrated taping unit secures trailing ends so paper edges do not unravel during handling and transfer.

Taping runs while the bundle moves, synchronized with the wrap so tail fastening stays off the critical path.

  • Surface Protection Standards: Anodized, powder-coated, electrophoretic or mill-finish requirements.
  • Wrapping Media Strategy: Kraft paper vs. stretch film, plus tape-banding requirements.
  • 용량 목표: Required output in metric tons per shift or master bundles per hour.

자주 묻는 질문 (FAQ)

What is the maximum package envelope the sub-bundle wrapper accepts?

The unit accepts cross-sectional package diagonals between 100 mm and 300 mm, lengths from 1,000 mm upward, and total weights between 15 kg and 100 kg.

What is the net packaging time for a standard 6-meter bundle?

At 12 m/min, pure wrapping travel takes 30 seconds; with feed-in, film cut and discharge, floor cycle time is about 40–45 seconds per sub-bundle.

Can the system wrap single extrusions without bundle grouping?

Yes, provided the profile diagonal exceeds the 100 mm OD limit. Smaller profiles need custom guides or grouped sub-bundling.

Why is end taping recommended for paper wrapping applications?

Unlike stretch film, kraft paper lacks natural cling. End taping stops trailing seams from tearing during transfer to the master stacking bed.

Can the wrapper switch between paper and stretch film on the same ring?

Yes. The tension carriage accepts standard 50 mm core rolls of crepe paper, woven tape or LLDPE film with adjustable tension.
