Mesin Pembungkus Kumparan Utama dengan Lubang Penghubung di Dalam Ruang Terpagar: Siklus Pembungkus yang Diberi Makan Konveyor

Ringkasan Eksekutif This clip follows one of our master coil wrappers through a full wrapping cycle, filmed from outside the yellow safety fence. The coil arrives on a conveyor, passes through the rotating wrapping ring and leaves sealed in film. The title mentions corner protectors; that station is not in this clip, so we explain the wrapping cycle shown and where edge protection fits in a master coil line.

Apa yang ditunjukkan dalam klip tersebut

The clip runs 172 s and is filmed by hand from the walkway outside the cell.

  • Pembukaan: the coil, bright bare steel, sits on the conveyor inside the yellow mesh fence. The machine frame is painted green.
  • From about 30 s: the camera moves to the access gate on the left side of the cell.
  • From about 55 s: the coil travels along the conveyor into the wrapping ring. The ring, with its film carriage, turns through the coil eye and lays film around the section in repeated passes.
  • From about 130 s to the end: the coil is fully covered in film and waits at the exit side of the ring.

The view is partly blocked by fence posts, so we do not read the coil size or the number of wraps from the footage.

How eye-through wrapping seals a master coil

In eye-through (orbital) wrapping, a ring carrying the film roll passes through the eye of the coil. While the ring turns, rollers under the coil rotate it slowly, so each pass overlaps the last. After one full coil turn, the whole section is covered, inside and outside, with no open edge.

For a master coil this matters because:

  • The inner wraps and the bore are covered, not just the outer face.
  • Overlap is set in the program, so the film layer is the same on every coil of a type.
  • No hand wrapping around a coil that can weigh several tonnes.

Our master coil wrapper uses two blocker roller stations that hold and turn the coil during orbital wrapping.

Which wrapper for which coil

Dari tabel model pembungkus gulungan baja kami:

Pilih Model coil ID coil OD Lebar gulungan Berat koil maks pemuatan
FCCA-1000 508 / 610 mm 700 – 1600 mm 20 – 400 mm 2000 kg conveyor
FCCA-1200 508 – 610 mm 800 – 1400 mm 20 – 500 mm 2500 kg conveyor
SPF-2000 508 / 810 mm 700 – 2500 mm 600 – 2500 mm 10000 kg derek

The clip shows conveyor feeding into the ring, which is how our FPCA models are loaded on automatic lines for narrower coils. Wide, heavy master coils move to crane loading, as on the FPS-2000. The model table is a starting point, not a full list. Each wrapper is built to the coil range of the project, so the figures can change.

Wrap materials and their weights

The default materials in our wrap-material calculator:

Bahan Berat Alasan umum untuk memilihnya
Film peregangan 20 g / m² dust and moisture barrier, see-through
Kertas kraft 185 g / m² surface protection for bright or polished coils
Kain tenun 115 g / m² tougher outer layer for rough handling

For a paper-and-film combination on a line, see steel coil packing with paper and stretch film. VCI film is also used on export coils, where corrosion during a long sea voyage is the main risk. The calculator takes the coil OD, ID and width, film width and overlap, so you can compare material use before you choose.

Edge and corner protection on master coils

Film alone does not stop a dent. The edges of a master coil take the knocks from forks, crane hooks and lashing in transit.

  • Corner or edge protectors go on the outer and inner edges of the coil to spread contact loads.
  • They must be in place before the final wrap, so the film holds them and no edge is left exposed.
  • On an automatic line this is a separate station before the wrapping ring, so the ring cycle time is not affected.

This clip covers only the wrapping ring. Tell us which edges need protection, and we lay out the station in your line drawing.

  • Coil ID, OD, width and weight range, smallest and largest coil.
  • Loading method: conveyor, coil car or crane.
  • Wrap material: stretch film, kraft paper, woven fabric or VCI film, and how many layers.
  • Edges that need protectors and whether you also strap the coil.
  • Coils per shift and the time available per coil.
  • Floor space, fence line and where operators load film.

Kontrol dan keamanan

Standar yang berlaku bergantung pada pasar tujuan. Untuk pasar CE, ISO 12100 menetapkan metode penilaian risiko dan EN 415-10 mencakup persyaratan umum untuk mesin pengemasan, yang menetapkan pengamanan dan pengaturan penghentian darurat.

In the clip the ring works inside a yellow mesh fence, with a gate control box and a red indicator light at the access gate. We set the gate logic and stop arrangement in the risk assessment for each project.

Pertanyaan yang Sering Diajukan (FAQ) tentang Teknik

Q: Does the clip show corner protectors being placed? A: No. It shows the eye-through wrapping cycle. Edge protection is a separate station ahead of the ring.

Q: What is the largest coil our wrappers take? A: Our model table lists the FPS-2000 up to 2500 mm OD, 2500 mm width and 10000 kg, with crane loading.

Q: Can the same machine use paper and film? A: Yes, as options. Stretch film, kraft paper, woven fabric and VCI film can all be specified, and we set the carriage for the materials you name per project.

Q: What holds and turns the coil during orbital wrapping? A: On our master coil wrapper, two blocker roller stations hold the coil and turn it through the ring.

Q: How is the film overlap controlled? A: The coil turns on rollers while the ring wraps, and the program sets the overlap for each coil type.

Q: Why put the wrapper inside a fence? A: The ring and the turning coil are moving hazards. The fence and gate keep people out of the cell while the cycle runs, and the risk assessment fixes the gate logic.

Langkah selanjutnya

We size a master coil wrapper in three steps:

  1. Kirimkan gambar tata letak Anda with the coil range, loading method and wrap material, to info@fhopepack.com.
  2. Terima proposal dalam waktu 48 jam, with the wrapper model, edge-protection station and cell layout.
  3. Pesan survei lokasi so we confirm conveyor height, crane access and the fence line.
