Πηνίο εύκαμπτου σωλήνα, πηνίο καλωδίου και παλέτα: Τρεις εργασίες περιτύλιξης, τρεις οικογένειες μηχανών

Περίληψη Packaging flexible industrial hose coils, insulated cable coils, and full multi-coil pallet loads requires matching the physical geometry of the workpiece to the correct machine kinematics. Ring wrappers apply protective film radially through the open center of individual coils, whereas turntable stretch wrappers unitize multi-layer stacks on a pallet base in an eye-to-sky vertical arrangement. Selecting between an orbital hose wrapper (FPH-300N), an orbital cable wrapper (FPCA-200), and a heavy-duty turntable pallet wrapper (A200) depends strictly on center-eye clearance, coil outer diameter, target packaging cycle time, and whether product units are destined for individual retail distribution or bulk warehouse transit.

Three workpieces, three geometries

Packaging operations handling flexible tubing, hydraulic lines, and electrical conductors encounter three distinct physical geometries. Each shape dictates how film tension must be applied to prevent load deformation, slippage, or moisture ingress:

• Hose coils: synthetic rubber, braided PVC or corrugated nylon, axial width 100–300 mm. They need continuous tension that pulls the loops together without collapsing the flexible wall.
• Cable coils: Electrical building wire, co-axial lines, and optical fibers wound into tight coils with outer diameters up to 1000 mm. They demand consistent surface overlap to shield jacketing from abrasion and retain dimensional stability during distribution.
• Φορτία παλετών: Cylindrical coils stacked vertically (eye-to-sky) on wooden or plastic pallets. The resulting assembly forms an upright cylinder that must resist horizontal inertia and transit shifting through perimeter unitization.

The primary geometric triage rule is clear: if a coil has an open center eye that can clear an orbital wrapping shuttle, it can be wrapped through-the-eye on a ring machine. If the coil has no accessible core, or if individual coils must ship unified on a single pallet footprint, the load must move to a turntable machine.

Ring machines: hose and cable coils

Ring packaging systems rely on a powered annular shuttle that rotates at high speed through the central opening of the coil while driven support rollers rotate the coil around its own axis. This synchronized dual-axis rotation creates a continuous, overlapping spiral layer across both the interior core and exterior circumference.

• Hose coil wrapping (FPH-300N): Built with heavy-duty guide rollers and dedicated tensioning arms engineered for hose manufacturing lines. Driven by a 1.9 kW motor, the ring reaches rotational speeds up to 120 r/min. It handles coils with an inner diameter (ID) between Φ300 mm and Φ700 mm, an outer diameter (OD) between Φ500 mm and Φ1000 mm, and axial widths between 100 mm and 300 mm, supporting individual coil weights from 10 kg to 100 kg.
• Cable coil wrapping (FPCA-200): Optimized specifically for rapid coil handling on electrical wire finishing lines. The machine applies a radial film layer with an adjustable overlap ratio of 20% to 80%, completing individual coils in 20 to 30 seconds. This uniform wrap secures the tail of the conductor and forms a sealed protective barrier against atmospheric oxidation and surface scuffing.

Turntable machine: pallet loads

When finished coils are prepared for bulk container transport, regional distribution, or direct OEM supply, wrapping coils individually through-the-eye is often neither cost-efficient nor operationally practical. Instead, coils are stacked in an eye-to-sky vertical column directly onto a pallet deck and wrapped as a single bulk entity.

The A200 Pallet Wrapping Machine accommodates these stacked loads using a heavy-duty turntable and mast-mounted film carriage:

• Turntable platform: Features a Φ1500 mm solid steel base plate with a 10 mm deck plate thickness and a low 80 mm profile for easy ramp loading. The rotating structure supports payloads up to 1800 kg, running smoothly at variable inverter speeds up to 13 r/min.
• Κορυφαία πίεση: light coils lack the deadweight to stay centered against film pull. A top press (motor or pneumatic, per the A600 and B200 pages) holds the stack down while the turntable turns; press force is set for the load, not taken from a fixed table.
• Προέκταση: 250% standard on the A200 (adjustable 100–300%), so 1 m of 500 mm film yields about 3.5 m of wrap at the 250% setting.

Size gate for each family

Before specifying drive gear ratios or line layouts, verify that your coil envelope complies with the physical boundaries of each machine family:

Critical Geometric Boundary: The Solid Coil Rule

If an operator presents a cable coil with an outer diameter of OD 600 mm that has no central core opening (for example, a wooden cable drum wound flush to the center, or a coil with a solid wooden core hub), it cannot pass through the rotating shuttle ring of an FPH-300N or FPCA-200. Attempting to process solid products on an orbital ring machine will cause direct mechanical interference with the film shuttle. These workpieces must bypass ring wrappers and route to the A200 turntable pallet wrapper or a custom orbital stretch wrapper with cantilever arms.

Cycle time side by side

• FPH-300N (hose coil): 23–35 s per coil, set by ring speed (up to 120 r/min) and overlap.
• FPCA-200 (cable coil): 20–30 s per coil, overlap preset 20–80%.
• A200 (pallet stack): time per pallet = turns × 60 ÷ 13 r/min + loading, with a base and top dwell turn added by the program. A 20-turn program is 20 × 60 ÷ 13 ≈ 92 s of turntable time before loading.

Shift output formula

Output per shift = (shift seconds × efficiency) ÷ cycle time

Take the shift seconds from your own calendar (an 8-hour shift is 28,800 s), set efficiency from your staging and film-change record rather than assuming a number, and plug in the cycle above. Run the same formula for each family before you compare them: a pallet of eight coils is one cycle on the A200, while the same eight coils are eight cycles on a ring machine — that difference, not the seconds alone, is what decides the machine.

Διάταξη και επιφάνεια δαπέδου

Both families are planned from the workpiece, not from a catalogue footprint:

• Ring wrapper: a linear line. Line length = infeed conveyor + ring station + outfeed conveyor, each set as ordered for your coil size; lateral width must leave room to load a film roll and to reach the ring for service. Area ≈ (infeed + ring + outfeed) × (ring width + service aisle).
• Περιτύλιγμα πικάπ: a bay, not a line. The A200 turntable is 1500 mm and the maximum turning envelope is 2000 mm, so the bay must clear the turning circle plus the mast and any top-press swing: bay width ≥ turning envelope + operator aisle. Add ramp or pallet-truck access in front of the turntable.

Write both areas into your layout drawing with the actual conveyor lengths you order; a footprint copied from a brochure will not match a line built around your coil.

Film and consumables

Consumables must match the mechanical delivery carriage of each system. Operating an orbital machine with improper roll dimensions or running uncalibrated film tension on a pallet wrapper leads to film snapping, excessive consumption, or loose wraps.

When one machine cannot do all three

High-mix plants often try to run everything on one wrapper. Physical limits stop that:

1. Ring opening: an FPH-300N (max OD Φ1000 mm) cannot clear a 1200 × 1000 mm pallet base.
2. Open cores: an A200 wraps the stack perimeter only; the top coil’s core stays open unless a top sheet or a through-the-eye wrap comes first.
3. Tandem two-stage layout: Στάδιο 1 wraps each coil through the eye on an FPH-300N or FPCA-200 (20–35 s); Πρακτική άσκηση 2 palletizes the wrapped coils and unitizes them on an A200. Buffer one pallet between the stages so a film change upstream does not stop the wrapper.

Συχνές ερωτήσεις μηχανικής

Q: Can the A200 wrap a single hose coil laid flat on the turntable? A: Yes, if the coil sits inside the load window (minimum load 500 × 500 × 500 mm on the A200 page). But it wraps the outer circumference only — film cannot pass through the center eye, so the coil core stays open.

Q: What keeps light hose coils from shifting when the turntable starts? A: A top press. On the A600 the press is driven by a motor or a pneumatic cylinder and holds the load still while the turntable turns; on the B200 it is a pneumatic top plate option. Press force is set for the load on your floor — start low, wrap one pallet, and raise it only until the stack stops shifting.

Q: How is guarding decided for these two families? A: By the site risk assessment. A ring machine needs the ring opening, film path and conveyor ends covered so nobody can reach the shuttle while it turns; a turntable needs the turning circle fenced with the load-height and mast positions taken into account. Interlocks are set to stop the ring or turntable when a gate is opened, and the final guarding layout is confirmed against the machine you order.

Q: What film can the FPH-300N run? A: Stretch film at OD 100–180 mm, ID 50 mm, width 90–100 mm; the FPH-400W page also lists paper, woven and HDPE at OD 200–450 mm, ID 50 mm, width 90–120 mm. Match the roll to the carriage you order.
