Steel wire uncoiler with dual purpose both for uncoiling and pallet moving

Invention: Steel Wire Uncoiler with Dual Purpose for Uncoiling and Pallet Moving

1. Overview

The Steel Wire Uncoiler with Dual Purpose for Uncoiling and Pallet Moving is an innovative piece of equipment designed for industries handling steel wire coils, such as those used in strapping production (e.g., 9mm blued steel strapping) or for securing loads like 4-inch/5-inch Schedule 40 steel pipes. This invention serves two primary functions:

• Uncoiling: Safely and efficiently uncoils steel wire from coils for feeding into production lines (e.g., strapping tempering, cutting, or packaging systems).
• Pallet Moving: Acts as a pallet mover to transport coils or finished products within the production facility, eliminating the need for separate pallet-moving equipment like forklifts or cranes.

2. Design Specifications

2.1 Structural Components

• Base Frame:
  • Material: Heavy-duty steel with a rugged, welded construction for durability [Web ID: 4].
  • Dimensions: 2.0 m x 1.5 m x 0.5 m (L x W x H) to provide stability and a low center of gravity, preventing tipping during pallet moving [Web ID: 4].
  • Weight Capacity: Up to 6000 lbs (2722 kg), suitable for heavy steel wire coils [Web ID: 3].
• Turntable:
  • Diameter: 1.5 m (59 inches), capable of handling coil outer diameters (OD) up to 72 inches [Web ID: 2].
  • Mounted on heavy-duty bearings for smooth rotation during uncoiling [Web ID: 4].
  • Features a center spider and wire basket to contain the wire coil securely [Web ID: 4].
• Mobility System:
  • Equipped with four heavy-duty wheels (two fixed, two swivel with brakes) for pallet-moving functionality.
  • Wheel Material: Polyurethane, capable of supporting 6000 lbs and resisting wear on factory floors.
  • Drive Mechanism: Powered by a 1 HP electric motor for controlled movement, with a maximum speed of 2 m/s (6.5 ft/s).
• Lifting Mechanism:
  • Hydraulic lifting arms (two arms, 1 m long) integrated into the base frame for pallet engagement.
  • Lifting Capacity: 3000 lbs (1361 kg) per arm, sufficient for lifting pallets of coils or finished products.
  • Lift Height: 0–150 mm (0–5.9 inches) to clear the floor during movement [Web ID: 17].

2.2 Uncoiling Features

• Wire Diameter Compatibility: Handles steel wire diameters from 0.050 inches (1.27 mm) to 0.630 inches (16.0 mm), suitable for strapping production [Web ID: 3].
• Coil Specifications:
  • Inner Diameter (ID): 18–20 inches (adjustable via a manual expansion mechanism) [Web ID: 2].
  • Outer Diameter (OD): Up to 72 inches [Web ID: 2].
  • Weight Capacity: 6000 lbs (2722 kg) [Web ID: 3].
• Payoff Mechanism:
  • Non-motorized turntable with an adjustable tension brake to prevent over-travel during uncoiling [Web ID: 4].
  • Variable speed control via a friction disc to reduce tangling, adjustable for smooth payout [Web ID: 9].
• Safety Features:
  • TangleGuard interlock system to prevent machine movement if a coil snag occurs [Web ID: 3].
  • Emergency stop circuit integrated into the control panel [Web ID: 17].

2.3 Pallet-Moving Features

• Pallet Compatibility:
  • Standard Pallet Size: 48 x 48 inches (1220 x 1220 mm), adjustable to accommodate smaller or larger pallets [Web ID: 19].
  • Load Capacity: Up to 6000 lbs, matching the uncoiler’s weight capacity.
• Lifting and Moving:
  • Hydraulic arms lift the pallet off the ground, allowing the wheels to move the load.
  • Joystick control for precise navigation within the production facility.
