执行摘要 For export wire coils, our packaging line takes each coil off the collecting rack, straps it, wraps it at separate paper and film stations, then weighs and labels it. Lines handle coils from 30 kg to over 6,500 kg, with 500–1,500 mm OD, at 20–40 coils an hour. Strapping takes up to 35 s a cycle and wrapping 20–120 s a coil. A worked example shows why two wrapping stations in a row keep a paper-and-film pack at full line rate.

What an export wire coil pack needs

A wire coil going by sea needs three things. Straps keep the rings tight while the coil is lifted and shaken. A moisture barrier keeps rust and water spots off through weeks of humid air. And a correct weight and label let the coil clear the port and reach the right customer.

Doing that by hand means a crane, a strapping tool, two people wrapping and a separate scale. On a line, each step has its own station and the coil moves between them on conveyors.

From collecting rack to labelled coil

1. 卸货。 The coil stands in a vertical collecting rack with upright posts. A manipulator grips it and pulls it out as the rack tilts back, then sets it on the roller conveyor.
2. 捆扎。 Green PET strap comes down from an overhead dispenser. The head tensions it round the coil section and seals it, then the coil indexes to the next strap point.
3. 包装。 Paper and film stations wrap the coil through the eye, each with its own ring.
4. 称重。 A scale weighs the coil on the conveyor, and the reading shows on a panel display.
5. 标签。 A print-and-apply labeller fixes the label, and the coil moves to the outfeed for stacking.

A signal tower on the control desk shows the line state, and yellow mesh guards cover the moving parts above the strapping and wrapping units.

Wire coil packaging line data

Worked example: the slowest station sets the rate

A plant ships wire coils overseas and wants paper under film on every coil. It needs 36 coils an hour. On its coils, the paper wrap takes 90 s, the film wrap 60 s and strapping 35 s. These are illustrative customer figures, inside the line's 20–120 s wrapping range.

Time per coil needed. 3,600 ÷ 36 = 100 s.

One wrapping station doing both. Paper then film on the same ring takes 90 + 60 = 150 s. The line can only manage 3,600 ÷ 150 = 24 coils an hour.

Two stations in a row. Each coil spends 90 s at the paper station and 60 s at the film station. Coils move through both stations at the same time, so the slowest station sets the pace. The slowest is paper at 90 s, giving 3,600 ÷ 90 = 40 coils an hour, more than the 36 needed.

捆扎。 Count the straps. If the 35 s cycle is per strap, two straps take 2 × 35 = 70 s, inside the 100 s budget. Three straps take 3 × 35 = 105 s, which drops the line to 3,600 ÷ 105 = 34 coils an hour and makes strapping the limit. A second strapping head or fewer straps fixes it.

Strap time depends on the head and strap. On one coiling line we quoted about 60 s for 4 straps, roughly 15 s a strap, and the strap count can be changed in the program.

The rule is: coils per hour = 3,600 ÷ (longest station time + t), where t is the transfer time between stations that we set in the layout.

Weighing and labelling for export papers

The scale weighs each coil on the line, so the weight on the label matches the coil. With 1/3,000 accuracy, a scale sized for 3,000 kg resolves to 3,000 ÷ 3,000 = 1 kg.

The labeller prints the weight and coil data, and the PLC and HMI track the pack online. Packing lists and port papers can then come from the same data.

现场条件

The equipment works from −10 °C to +45 °C. The electrical cabinets need air conditioning at 23 ± 2 °C, which matters in a hot, humid port-side plant. All contact surfaces that touch the wire, on rollers and tilters, are PU coated against scratching.

选择清单：我们需要发送哪些内容

1. Coil OD, ID and width, smallest and largest.
2. 最重的线圈。
3. 每小时线圈数。
4. Strap: PET or steel, and how many per coil.
5. Wrap: paper, film or both, and the order.
6. Label data and the scale capacity you need.

安全与 EN 415-10

We build our coil packaging lines to CE requirements, with EN 415-10 as the reference and an ISO 12100 risk assessment. The main hazards are the manipulator, the strapping head, the turning wrapping rings and the conveyors.

Mesh guards cover the moving parts above the stations. Fence the manipulator and conveyors, with interlocked gates or light curtains chosen in the risk assessment, so the line stops if someone enters. The signal tower shows when the line is in automatic.

工程常见问题解答

Q: Can we start with strapping only and add wrapping later? A: Yes. The add-ons are modular, so stations can join the line later.

Q: PET or steel strap for export coils? A: Both heads are available. We choose by coil weight and how the coil is lifted at the port.

Q: Will the line mark galvanised or coated wire? A: The rollers and tilters that touch the wire are PU coated to prevent scratching.

Q: Which safety standards apply? A: EN 415-10 is our reference for CE markets, backed by a risk assessment to ISO 12100.
