خط بسته بندی و تسمه کشی کویل دو مرحله ای

خلاصه اجرایی A coil that is wrapped and strapped keeps its outer wraps tight, eliminates layer telescoping, and secures internal tail ends during downstream handling and transport. The stretch wrapping and radial strapping units operate as a modular two-station sequence rather than a rigid single-chassis machine. For an operational target of 20 coils per hour, available takt time is 3,600 / 20 = 180 s per coil. The governing station cycle—or the combined wrap-plus-strap cycle if executed on a single shared indexer—must remain comfortably within this takt window. Station layouts and conveyor links are engineered to fit facility footprints.

کاری که دستگاه انجام می‌دهد

At the wrapping station, the coil rests horizontally on motorized support rollers. A precision rotating ring carries the film carriage directly through the coil eye (inner diameter), applying high-retention stretch film as the support rollers rotate the coil. This process applies continuous, overlapping containment across the coil outer diameter (OD), inner diameter (ID), and both side faces.

At the strapping station, an overhead gantry carrying a heavy-duty strapping head lowers over the coil on the conveyor. A segmented guide track traverses the coil eye, forming an automated loop that tensions, seals, and cuts high-strength PET strapping. An integrated scissor-lift table at the terminal end of the strapping line facilitates transfer and buffering.

The two stations

Applying stretch film first seals the outer wraps, stabilizes loose strip ends, and provides continuous moisture and surface protection. Subsequent radial strapping clamps down over the film, absorbing dynamic shock loads during crane hoist movements, fork truck handling, and transit.

Whether these stations are linked by a continuous powered roller conveyor or configured as decoupled workstations depends on plant layout and buffer requirements. For fully automated slit coil processing lines featuring automated sorting, strapping, through-eye wrapping, and downending, consult our خط بسته بندی کویل شکاف دار برای مراکز خدماتی.

پیچیدن کویل از طریق چشم

An eye-through coil wrapper uses an open/close or C-type/annular rotating ring to orbit stretch film through the center bore, wrapping both faces, the OD, and the ID simultaneously. This configuration shares core drive kinematics with our specialized non-ferrous and copper strip coil packaging equipment. Wrapping speed, film overlap percentage, and pre-stretch rates are adjusted via the PLC interface.

Reference specifications for the standard FPC-200 eye-through wrapper:

For heavier strip bundles and higher mass capacities, the FPC-300 chassis provides reinforced structural support:

Total wrap cycle time is governed by coil dimensions, selected film width (typically 90–150 mm), and programmed overlap ratio.

پیچاندن سیم پیچ از طریق چشم

Following the wrapping stage, high-tensile PET strapping secures the bundle integrity. Detailed information on this engineering class is available in our دستگاه تسمه شعاعی سیم پیچ فولادی بررسی اجمالی.

The custom-engineered eye-through strapping system applies radial straps through the center bore. As an engineering baseline, reference specifications for our industrial PET eye-through strapping platform include:

Actual tension limits, strap counts (e.g., 2, 3, or 4 radial ties), and rotation angles are programmed to match product specifications and shipping standards.

خروجی، زمان چرخه خط و takt

Takt time is dictated by plant production quotas rather than individual machine velocity. The engineering validation below demonstrates an operational target of 20 coils per hour:

When wrapping and strapping operate on decoupled conveyor stations, line cycle time is governed strictly by the slower unit (the strapping station at 48–60 s), leaving substantial headroom within the 180 s takt allowance. If both operations are integrated into a single combination station, total process time equals the sum of both sequences (71–110 s), which still operates well inside the required 180 s threshold.

کنترل‌ها و ایمنی

Orbital wrapper rings and gantry strapping heads exhibit high-inertia mechanical motion through open coil cavities. Personnel entry into the ring rotation zone, strapping head descent envelope, or indexing roller conveyors is strictly prohibited during automatic operation. Maintenance, film roll changes, or fault interventions must only occur once the equipment is fully stopped, verified zero-energy, and locked out under established LOTO protocols.

Safety architectures conform to the destination country’s machinery directives. For CE installations, risk assessments comply with ISO 12100, and integrated safeguarding (light curtains, perimeter interlocks, and emergency stop circuits) satisfies EN 415-10 standards for packaging machinery.

• Coil dimensional envelope: minimum and maximum OD, ID, face width, and total mass.
• Required continuous throughput capacity (coils per hour).
• Packaging material specifications: stretch film width, core diameter, film thickness, and target overlap percentage.
• Strapping parameters: strap grade (PET/PP), width, thickness, strap count per coil, and tension requirements.
• Material flow layout: single continuous powered conveyor vs. dual decoupled stations, including discharge elevation changes.
• Plant infrastructure: floor loading limits, pneumatic supply parameters (flow/pressure), and electrical service specifications.

سوالات متداول مهندسی

Q: Why wrap the coil through the eye before strapping it? A: Eye-through wrapping establishes complete environmental containment across the OD, ID, and both side faces while support rollers slowly rotate the coil. This prevents strip edge damage and telescoping, allowing subsequent PET straps to securely bind over the film without scoring metal edges.

Q: Why are the two stations shown as a sequence? A: Presenting the machines as decoupled modules highlights their standalone mechanical functions. It does not dictate a fixed conveyor link; transfer decks, turnstiles, or indexing chains can be engineered to suit specific facility layouts.

Q: How fast is the strapping? A: On our PET eye-through strapping head, strap feeding, tensioning, sealing, and cutting takes approximately 12–15 s per strap. A standard four-strap radial pattern completes in 48–60 s, excluding coil indexing rotation.

Q: Can the wrap and strap share a takt? A: Yes. On separate stations, the governing cycle time is simply that of the slower machine. On a single shared station, cumulative cycle time equals the wrap sequence (23–50 s) plus the strap sequence (48–60 s), yielding 71–110 s total, which easily satisfies a 180 s takt (20 coils/hour).

Q: Which wrapper fits my coil? A: Bundles within 600–1,200 mm OD, 300–800 mm ID, and weights up to 500 kg are handled by the FPC-200. For heavier industrial bundles up to 1,000 kg with IDs of 400–900 mm, the heavy-duty FPC-300 chassis is recommended.
