Вращающийся роликовый упаковочный станок B200: Встроенный роликовый поворотный стол с пневматической верхней пластиной.

Резюме The B200 inline turntable stretch wrapper integrates directly into automated conveying lines, eliminating manual forklift staging by automatically receiving, wrapping, and discharging palletized goods. Engineered with a heavy-duty roller turntable, it supports standard payloads of 2,000 kg (expandable to 3,000 kg) with variable-frequency rotational speeds of 3–12 rpm. An integrated pneumatic top plate stabilizes lightweight, loose, or tall loads during the rotation cycle, while infeed, turntable, and outfeed roller conveyors operate on a single coplanar level for smooth transfer.

Как работает встроенный цикл B200

The B200 integrates upstream packaging, stretch wrapping, and downstream logistics into a single continuous handling cycle. By eliminating forklift transport at the wrapping station, it minimizes product handling damages and maintains consistent line velocity.

A standard automated wrapping sequence proceeds as follows:

  1. Infeed Transfer: The pallet moves from the plant infeed roller conveyor onto the motorized roller turntable. Both systems are aligned coplanar at identical pass-line heights (typically 450 mm to 550 mm above finished floor level) to prevent pallet tipping or roller impact shocks.
  2. Стабилизация нагрузки: For unstable or lightweight stacks, the overhead pneumatic platen lowers, applying controlled vertical pressure (0.2–0.6 MPa adjustable) to secure the upper tiers.
  3. Automated Height Detection & Wrapping: A retroreflective photoelectric sensor detects the top edge of the load. The variable-frequency drive (VFD) accelerates the turntable smoothly up to target speed (3–12 rpm), while the power pre-stretch carriage ascends and descends along the mast to apply programmed bottom, body, and top wrap counts.
  4. Pneumatic Clamping & Cutting: Upon cycle completion, the pneumatic clamp captures the film tail, an impulse hot-wire or serrated blade severs the web, and a wipe-down brush secures the trailing film edge flush against the load.
  5. Выпуск готовой продукции: The top platen retracts upward, and the synchronized double-strand chain-driven turntable rollers discharge the wrapped unit load onto the outfeed accumulation conveyor.

The turntable roller bed utilizes a continuous double-strand drive chain mechanism, ensuring zero roller slippage under concentrated 2,000–3,000 kg downward loads.

Film changeover downtime is optimized: the pre-stretch carriage features an easy-access open-door threading design, reducing roll replacement time to approximately 10 seconds.

Когда необходима пневматическая верхняя пластина

The pneumatic top stabilizing plate applies constant downward clamping force to the upper load face during turntable rotation. This device is required under the following operating conditions:

  • Low-Density or Empty Cartons: Lightweight corrugated packaging tends to drift or deform when subjected to high film web tension at perimeter corners.
  • Unbonded Top Tiers: Unbanded, unglued, or column-stacked boxes and bags can dislodge due to centrifugal forces before containment film wraps the upper edge.
  • High Aspect Ratio Stacks: Pallet units with a high center of gravity (stack height greater than 1.8 × pallet width) experience pronounced overturning moments during the rotational start phase.

For dense, high-friction, interlocked loads (e.g., rigid wooden crates or filled liquid drums), the cycle operates in bypass mode with the top platen locked in the upper home position.

Cycle time and throughput dynamics at 3–12 rpm

Total cycle time per pallet (T_cycle) consists of turntable rotational wrapping time plus mechanical conveyor handling and auxiliary sequence steps:

T_cycle = T_acc/dec + (N_winds ÷ RPM × 60) + T_infeed + T_outfeed + T_aux

Где:

  • N_winds: Total carriage turns applied across base reinforcement, upward traverse, top overlap, downward traverse, and base tie-off.
  • RPM: Programmed steady-state turntable speed (3–12 rpm).
  • T_aux: Cumulative time for top platen motion, photoelectric load sensing, and automated cut/wipe sequences (typically 12–18 seconds).

Representative Cycle Time Calculations (Assuming 15 Total Rotational Winds)

  • High-Throughput Configuration (12 rpm, Stable Loads):
    • Rotational Phase: 15 winds ÷ 12 rpm = 1.25 minutes (75 seconds)
    • Infeed, Outfeed, Soft Start/Stop, and Cut: ~25 seconds
    • Общее время цикла: ~100 seconds per pallet (~36 pallets per hour)
  • High-Care Configuration (3 rpm, Fragile or Unstable Stacks):
    • Rotational Phase: 15 winds ÷ 3 rpm = 5.00 minutes (300 seconds)
    • Infeed, Outfeed, and Top Plate Settling: ~30 seconds
    • Общее время цикла: ~330 seconds per pallet (~10–11 pallets per hour)

Turntable acceleration and deceleration ramp rates are tuned in the OMRON PLC to prevent load shifting during speed transitions.

Film carriage and power pre-stretch system

The B200 utilizes a powered dual-roller pre-stretch film delivery carriage:

  • Механическое преимущество: Standard 200% pre-stretch ratio mechanically elongates 1 meter of stretch film into 3 meters on the product. This reduces consumable film mass per pallet by up to 55% compared to friction-brake carriages.
  • Drive Separation: A dedicated DC motor powers the pre-stretch rollers, isolating film elongation tension from the load-wrapping tension.
  • Контроль натяжения: Web tension applied to the pallet corners is modulated via an analog dancer-arm potentiometer or load-cell feedback, preventing corner crushing on soft corrugated cartons.
  • PLC Wrap Recipes: Bottom wrap counts, top reinforcement wraps, carriage elevation traverse speed, and intermediate reinforcement bands are independently configurable through the HMI screen.

  • Stack Integrity: Presence of loose top layers, light cartons, or high centers of gravity requiring a pneumatic top plate.
  • Уровень автоматизации: Requirement for fully automated pneumatic film clamping, cutting, and heat-wiping mechanisms.
  • Footprint & Access: Layout clearance for safety perimeter fences, maintenance access gates, and LOTO (Lockout/Tagout) power disconnects.

Часто задаваемые вопросы по инженерным вопросам

What is the maximum load capacity of the B200 turntable?

The standard B200 roller turntable is structurally rated for dynamic payloads up to 2,000 kg. For heavy industrial goods such as metal ingots, chemicals, or refractory blocks, an optional reinforced slewing bearing carriage upgrades total load capacity to 2,500–3,000 kg.

How does the pneumatic top plate prevent pallet damage?

The top plate uses a regulated pneumatic cylinder that exerts a controlled vertical clamping force downward onto the load. This prevents shifting or corner lift on light, unbanded cartons while allowing variable pressure adjustment (0.2–0.6 MPa) to avoid crushing fragile product boxes.

What rotational speeds does the turntable support?

The turntable is driven by an industrial gearmotor governed by an adjustable variable-frequency drive, operating smoothly between 3 rpm and 12 rpm. Acceleration and deceleration profiles are set within the PLC to prevent rotational load tipping.

Can the B200 operate as a fully unmanned packaging station?

Yes. When paired with powered infeed/outfeed roller conveyors and the automated pneumatic film clamping and cutting mechanism, the wrapper runs without an operator. Pallets index automatically into position, wrap according to stored recipe parameters, and discharge without manual intervention.

How long does a stretch film changeover take?

Film roll threading requires approximately 10 seconds. The power pre-stretch carriage incorporates a wide-opening latch door, allowing operators to drop in standard 500 mm (20 in) film rolls and thread the web across pre-stretch rollers without tools.
