Báo cáo tóm tắt
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 Đường kính ngoài từ 100 mm đến 300 mm and lengths exceeding 1,000 mm at line speeds up to 12 m / phút. 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.

The Stations in the Packaging Line
Plant layout, extrusion press capacity and profile specifications dictate the line topology. A standard automated packaging line integrates seven core stations:
| Station Step | Hệ thống chức năng | 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 | Thu thập và sắp xếp các gói con | 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.

How the Sub-Bundle Wrapper Works
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)- Định tâm: Conical vertical rollers centre incoming profiles on the pass-line.
- Giữ xuống: Pneumatic rollers clamp the extrusions to the bed, preventing twist, splay and vibration at high ring speed.
- Kiểm soát chu kỳ: 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:
| Tham số | Specification Window | Ghi chú kỹ thuật |
|---|---|---|
| Bundle Cross-Section (OD) | 100 mm đến 300 mm | Diagonal must clear the inner ring |
| chiều dài bó | Từ 1,000 mm đến hơn 6,000 mm | Extension conveyors sized per layout |
| Sub-Bundle Weight | 15 kg đến 100 kg | Within standard conveyor loading |
| Wrapper Conveyors | 2,000 mm infeed / 2,000 mm outfeed | Dấu chân cơ sở |
| Tốc độ băng tải tuyến tính | 6 m/phút đến 12 m/phút | Điều khiển bằng VFD |
| Tốc độ quay vòng | 20 RPM đến 90 RPM | Inverter driven |
| Nominal Wrap Output | 5 m/phút đến 15 m/phút | Governed by overlap and travel |
| Spiral Overlap Range | 10% đến 90% | Adjustable via VFD and ring speed |
Ví dụ: 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 12 m / phút 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:
| Tốc độ cuộn tuyến tính | Pure Wrap Cycle (6 m bundle) | Thông lượng tối đa lý thuyết |
|---|---|---|
| 12 m / phút | 30 giây | 120 bó/giờ |
| 5 m / phút | 72 giây | 50 bó/giờ |
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.
| Material Handling Item | Thông số kỹ thuật |
|---|---|
| Supported Packaging Media | Paper or stretch film |
| Supply Roll Core Diameter | Đường kính trong 50 mm |
| Supply Roll Width & Outer Diameter | 100 mm to 200 mm width; 100 mm to 200 mm OD |
| Kiểm soát căng thẳng | Adjustable, mechanical or pneumatic |
| Cut-and-Feed Mechanism | Automatic cutter and mechanical arm feed |

Những câu hỏi thường gặp (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.
