Steel Coil Handling

  • Coils can weigh several tons, requiring robust gripper mechanisms, lifters and conveyors to transport and position them efficiently.
  • Secure clamps or vacuum cups are needed to hold the coils during the packing process without distortion.

Coil Wrapping

  • Wrapping machines must apply layers of stretch film, foam, cardboard sheets and end protectors precisely to conform tightly to the coil geometry.
  • Adjustable wrapping mandrels and frame dimensions are necessary to accommodate different sized coils.
  • High tension control of the wrapping material is critical to achieve a durable yet flexible containment.

Paper Covering

  • Paper rolling machines can apply 1-2 layers of kraft paper or abrasion-resistant film around the base of the coil to protect surfaces during transport and storage.
  • The paper unroll mechanisms must synchronize with the coil rotation to achieve an even wrap.
  • Adhesive is typically applied to bond the paper to the underlying layer(s) and seal any edges.

Coil Strapping

  • Automatic strapping heads radially apply 1-4 overlapping bands around the outside diameter of the packed coils using steel or polyester straps.
  • Controllable tension mechanisms need to apply the optimal securement forces for different sized coils.
  • Sealing systems bond the strap ends to prevent loosening during handling and vibration.

Overall, developing an effective automated packing solution for cold rolled steel coils requires integrating subsystems across material handling, wrapping, covering and strapping – designed and optimized as a unified system accounting for the heavy weights, large dimensions and wide range of coil sizes involved.
