ملخص تنفيذي Our coil packaging solution for slitting lines takes coils of 80–5,000 kg from a 40 t cross arm, down-ends them, straps them with PET, wraps them, weighs and labels them, and stacks them on a 6-station turntable. The turntable lets several pallets build at once, so coils from one slit set can go to different orders. A worked example plans straps, stacks and turntable stations for one slit set.

The packing problem after a slitter
A slitter delivers a whole set of narrow coils at once, often for several customers. Each coil needs straps, a protective wrap, a weight and a label, and it has to land on the right pallet. Doing that by crane means slow lifts, mixed-up pallets and damaged edges.
Our line does it coil by coil, automatically, and sorts the coils onto pallets as it goes.
What the line does on the shop floor
On our demonstration line, a green down ender tilts a slit coil back and lays it on a yellow roller conveyor. The coil travels to the wrapping station, where an arm wraps it in white film. A yellow mesh fence closes off the machines. Further along, the wrapped coil passes an automatic unit that marks it, then runs on to the end of the conveyor.
Modules from cross arm to turntable
Cross arm. The slit set goes onto a rotating cross arm, rated 10 t per arm and 40 t in total. It turns automatically to present the next set.
Down ender. It takes one coil at a time off the arm and lays it on the conveyor.
PET strapper. Eye-through PET straps go on automatically at 3, 4 or 6 points, with a 15 s strapping cycle.
غلاف. Film, paper or woven fabric goes on through the eye for 360° protection.
Weighing and labelling. Net and gross weight are captured, and a barcode label is applied.
Centring table, stacker and turntable. The coil is centred, picked by the stacker with an electromagnetic or vacuum lifter, and set on one of six pallet stations on the turntable.

Why a 6-station turntable
A single stacking point has to stop while a full pallet is taken away. A turntable with six stations keeps going: one pallet fills while another is discharged or a new one is set down.
It also sorts. Each station can hold a different order, so coils of one slit set go straight to the right pallet. That removes the restacking step that usually follows a mixed set.
Weighing, labels and ERP
Every coil is weighed on the line, and its net and gross weight go onto a barcode label. With ERP integration over Profinet, the line can receive the order data and send back the weights. So the packing list matches what is actually on each pallet.
Worked example: one slit set from arm to pallets
A service centre slits a 1,200 mm OD, 508 mm ID master coil, 1,000 mm wide, into 8 strips of 120 mm plus 40 mm of edge trim. Five strips go to one order and three to another. These are illustrative customer figures.
Arm load. The coil’s cross-section is π ÷ 4 × (1.2² − 0.508²) = 0.928 m². The master coil weighs 0.928 × 1.0 × 7,850 = 7,285 kg, inside the 10 t per arm.
One strip. Each 120 mm coil weighs 0.928 × 0.12 × 7,850 = 874 kg, inside the 80–5,000 kg range. The 8 coils weigh 8 × 874 = 6,992 kg; the other 293 kg leaves as trim.
ربط. With 4 straps and one 15 s cycle per strap, strapping takes 4 × 15 = 60 s per coil. With 3 straps it is 45 s.
الأكوام. The first order’s 5 coils weigh 5 × 874 = 4,370 kg and stand 5 × 120 = 600 mm high. With a 150 mm pallet that is 750 mm, inside the 1,000 mm and 6,000 kg limits. The second order’s 3 coils go to a second station.
المحطات. One slit set uses two of the six stations. So the turntable can hold part-built pallets for up to three slit sets before any must leave.
قاعدة عامة. Coils per stack = the smaller of 6,000 ÷ coil weight and (1,000 − pallet height) ÷ coil width.

السلامة والمعيار الأوروبي EN 415-10
For CE markets we follow EN 415-10 as the reference, with a risk assessment to ISO 12100. The main hazards are the rotating cross arm, the down ender, the strapping head, the wrapping ring, the stacker and the turning turntable.
Fence the line, as on our demonstration line, and interlock the gates. The line removes operators from the heavy-load zones; keep it that way during production.
أسئلة وأجوبة هندسية
Q: Can the line handle copper and stainless coils as well as steel? A: Yes. It is built for steel, copper and aluminium slit coils, with soft handling for sensitive surfaces.
Q: Why PET strap rather than steel? A: PET strapping runs automatically on this line at 3, 4 or 6 points. Tell us if your customers require steel strap.
Q: Can the line talk to our ERP? A: Yes. It integrates over Profinet with your ERP for order data and weights.
س: ما هي المعايير التي تتبعونها في البناء؟ ج: معيار EN 415-10 كمرجع لشهادة CE الخاصة بنا، مع تقييم للمخاطر وفقًا لمعيار ISO 12100.
