Definitions

  • the present disclosure relates to a hand-held strapping device and method of operation thereof.
  • Strapping devices are used to form a tensioned loop of plastic strap (such as polyethylene or polypropylene strap), metal strap (such as steel strap), or paper strap around a load, such as a palletized load of boxed products or a large bundle of stacked lumber.
  • plastic strap such as polyethylene or polypropylene strap
  • metal strap such as steel strap
  • paper strap around a load, such as a palletized load of boxed products or a large bundle of stacked lumber.
  • Hand-held strapping tools and larger, standalone strapping machines are two types of strapping devices.
  • an operator pulls strap leading end first from a strap supply, wraps the strap around the load, and positions the leading end of the strap below another portion of the strap.
  • the operator then introduces one or more (depending on the type of strapping tool) of these overlapped strap portions into the strapping tool and actuates one or more buttons to initiate: (1) a tensioning cycle during which a tensioning assembly tensions the strap around the load; and (2) after completion of the tensioning cycle, a sealing cycle during which a sealing assembly attaches the overlapped strap portions to one another (thereby forming a tensioned strap loop around the load) and during which a cutting assembly cuts the strap from the strap supply.
  • Certain strapping tools configured for plastic strap include friction welders, heated blades, or ultrasonic welders configured to attach the overlapping portions of the strap to one another
  • Certain strapping tools configured for plastic strap or metal strap include jaws that mechanically deform (referred to as “crimping” in the strapping industry) or cut notches into (referred to as “notching” in the strapping industry) a seal element positioned around the overlapping portions of the strap to attach them to one another.
  • Certain strapping tools configured for metal strap include punches and dies configured to form a set of mechanically interlocking cuts in the overlapping portions of the strap to attach them to one another (referred to in the strapping industry as a “sealless” attachment).
  • a typical strapping machine includes a support surface (such as a raised tabletop for smaller machines or large-scale conveyors for larger machines) that supports the load, a strap chute that circumscribes the support surface, a strapping head that forms the strap loop, a controller that controls the strapping head to strap the load, and a frame that supports these components.
  • a typical strapping head includes a strap-feeding assembly for feeding strap from a strap supply into and around the strap chute and for retracting the strap so it exits the strap chute and moves radially inwardly into contact with the load, a strap-tensioning assembly for tensioning the strap around the load, and a strap-sealing assembly for cutting the strap from the strap supply and attaching two areas of the strap together to form the strap loop.
  • the strapping head includes several guides that define strap channels that the strap passes through as it moves between the various assemblies of the strapping head. The strap channels and the strap chute together define a strap path that the strap moves through.
  • the strapping machine To strap the load, the strapping machine carries out a strapping cycle including a strap-feeding cycle, a strap-retraction cycle, a strap-tensioning cycle, and a strapsealing cycle.
  • the strapping machine first carries out the strap-feeding cycle during which the strap-feeding assembly feeds strap (with the leading strap end first) from the strap supply through the strap-tensioning assembly, through the strap-sealing assembly, and into and around the strap chute until the leading strap end returns to the strap-sealing assembly.
  • the strapping machine then carries out the strap-retraction cycle during which the strap-sealing assembly holds the leading strap end while the strap-feeding assembly retracts the strap to pull the strap out of the strap chute and onto and around the load.
  • the strapping machine then carries out the straptensioning cycle during which the strap-tensioning assembly tensions the strap to a designated strap tension.
  • the strapping machine then carries out the strap-sealing cycle during which the strap-sealing assembly either (1) cuts the strap from the strap supply to form a trailing strap end and attaches the leading and trailing strap ends to one another in one of the manners described above, or (2) attaches the leading end to a portion of the strap that becomes the trailing strap end and then cuts the strap from the strap supply, thereby forming a tensioned strap loop around the load and completing the strapping cycle.
  • Various embodiments of the present disclosure provide a hand-held strapping device and method of operation thereof.
  • a strapping device for forming a loop of strap around a load
  • the strapping device includes: a housing configured to support a supply of strap; a jaw assembly comprising a first jaw and a second jaw, wherein the first jaw is movable relative to the second jaw, the jaw assembly extending from the housing and at least partially defining a strap chute circumscribing a load-receiving area; a strapfeeding assembly configured to feed strap from the supply through the strap chute and retract the strap from the strap chute; and a sealer-cutter assembly configured seal two portions of the strap together and to cut the strap from the supply to form the loop of strap.
  • Various embodiments of the present disclosure provide a method of operating a strapping device, wherein the method includes: moving at least one of two jaws of a jaw assembly to an open position; positioning a load between the two jaws; moving at least one of the two jaws to a closed position; activating a strap-feeding assembly to feed strap through a strap chute defined by the jaws and around the load; applying tension to the strap; sealing the strap; and cutting the strap.
