Two-Stage Copper Coil Packing Line: Eye-Through Wrapping and Stacking on Timber Runners

Executive summary A two-stage copper coil packing line separates the work: in stage one, each coil lies flat on powered rollers and a vertical ring wraps it through the eye in film. In stage two, a column stacker sets the wrapped coils on timber runners at marked stack positions, and a separate roller-table tilter turns between vertical and horizontal. Below we explain why the two stages are separated and what to specify for each.

What the machine does

The line runs three stations:

  1. Eye-through wrapping: a coil lies flat, eye vertical, in a vertical ring that turns through the eye and lays film over the outside, the bore and both faces.
  2. Slewing column stacking: a column stacker picks each wrapped coil, swings it out and lowers it onto timber runners at floor stack positions.
  3. Roller-table tilter: pivots coils through 90° between eye to sky and eye to wall, matching the plant’s dispatch rule.

Why wrapping and stacking are separate stages

Separating the two stages has clear benefits:

  • Each coil is sealed on its own. Coils can later be taken off a stack one by one without opening a package.
  • The ring only fits one coil. A ring sized for a full stack would be larger and slower.
  • The stacker works off-line from the ring. While the stacker builds a stack, the ring is already wrapping the next coil.

Stage one: eye-through wrapping

The ring passes through the eye while the rollers turn the coil, so film covers the outside, the bore and both faces. On our coil packing lines, PLC/HMI programs set centring, tension and overlap per coil type. Film, paper or woven wrap can be specified, with PET or steel strapping to follow, as on our two-stage coil wrapping and strapping line.

Stage two: stacking on timber runners

The stacker is a slewing column with an arm. It picks a wrapped coil and swings it out to a stack position on the floor.

  1. Timber runners are laid at the stack position.
  2. The arm lowers the first coil onto the runners.
  3. The next coil goes on top, eye vertical, until the stack is complete.
  4. A forklift takes the stack away on the runners.

Our copper coil packaging line lists ±2 mm stacking accuracy [manufacturer rating] and an automatic timber runner dispenser as an option, so runners need not be placed by hand. The automatic coil packing line allows up to 6 coils per stack.

The roller-table tilter

The third machine is a tilter with a roller table: coils roll on, and the table tilts through 90° between eye vertical and eye horizontal.

This is how a line meets the dispatch rule: coils eye to sky on runners, or eye to wall. The automatic coil packing line offers both.

What changes for copper coils

Copper strip and coils mark easily. On our copper coil packaging line:

Engineering Parameter Specified Value Technical Note
Item Value
— —
Coil weight, basic version 20–1,500 kg
Coil weight, standard version 100–4,000 kg
Contact parts PU (polyurethane) coated
Stacking accuracy ±2 mm
Controls Siemens PLC and HMI, auto/manual
Timber runners automatic dispenser, option

PU-coated contact parts keep steel off the copper surface during transfer, tilting and stacking. Every line is configured per project, so the coil range and options can change.

Selection checklist for a two-stage line

  • Coil OD, ID, width and weight, smallest and largest.
  • Wrap material and overlap; strapping after wrapping or not.
  • Stack height, stack pattern and timber runner size.
  • Eye to sky or eye to wall at dispatch.
  • Coils per hour and how stacks leave the floor.
  • Surface sensitivity: bare copper, tinned, or coated.

Controls and safety

The standards that apply depend on the destination market. For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 covers general requirements for packaging machines, which fixes guarding and the emergency-stop arrangement.

The slewing stacker sweeps an area of floor, so its stack positions sit inside the guarded zone. Fencing and stop circuits are fixed in the risk assessment for each layout.

Engineering FAQ

Q: Why not wrap the whole stack instead of each coil? A: Single coils are taken off the stack later and dispatched separately. Wrapping each coil keeps the rest of the stack sealed when one coil is removed.

Q: How heavy can the coils be? A: Our copper coil packaging line lists 20–1,500 kg for the basic version and 100–4,000 kg for the standard version [manufacturer rating].

Q: How does the line avoid scratching copper surfaces? A: Contact parts on our copper coil packaging line are PU (polyurethane) coated, so steel does not touch the copper during transfer and stacking.

Q: How accurate is the stacking? A: The copper coil packaging line lists ±2 mm stacking accuracy [manufacturer rating].

Q: Do the timber runners have to be placed by hand? A: No. An automatic timber runner dispenser is an option on our copper coil packaging line, which lays the runners before the stacker sets the first coil.

Q: Can the line pack eye to wall as well as eye to sky? A: Yes. The roller-table tilter turns coils through 90° between the two orientations.

Next step

We plan a two-stage coil packing line in three steps:

  1. Submit your layout drawing with coil range, stack pattern and dispatch orientation, to info@fhopepack.com.
  2. Receive a proposal within 48 hours, with the wrapper, stacker, tilter and floor layout.
  3. Book a site survey so we confirm stack positions, forklift routes and the guarded zone.
