  • the invention relates to a wrapping machine using a film material as the wrapping material.
  • the prior art discloses a variety of wrapping machine types for wrapping plastic film in the form of a web around goods to be packaged.
  • the goods to be packaged is typically a load placed on a pallet, said load being generally an entity in the form of a rectangular parallelepiped.
  • wrapping machines plastic film is wound around a load either by rotating rolls of plastic film web around a pallet or by turning a pallet with respect to rolls of plastic film web, or by performing both at the same time, whereby the rolls of plastic film web are also simultaneously moved in vertical direction.
  • Wrapping machines are also typically equipped with means of providing a piece of film web for covering a top surface of the load to be wrapped.
  • One known way of providing a movable wrapping machine is to combine the wrap- ping machine with a forklift used in picking up and moving the pallets. Hence, the wrapping machine can be brought into action as necessary and set aside when no more wrapping is needed, thus avoiding the need of reserving a permanent location for the wrapping machine. This results for example in a more space-efficient packaging process.
  • One known wrapping machine connectable with a forklift is disclosed in patent publication EP 1 489 004, which comprises a support structure consisting of a fork- shaped lower support section extending in horizontal plane and based against the floor, a vertical support section extending vertically from an edge of the fork-shaped support section, as well as an upper support extending from the end of the vertical support section in horizontal plane within a range defined by the lower support section.
  • the upper support has attached to its distal end an arm portion extending in horizontal plane rotatably relative to its attachment point, said horizontal arm portion having attached to its distal end a vertical arm portion extending vertically downwards.
  • This vertical arm portion has attached thereto film dispensing elements comprising a roll of film, which elements are displaceable along the vertical arm portion during the process of wrapping the film around a load to be wrapped up.
  • the present invention provides a solution which offers a movable wrapping machine with two wrapping stations.
  • the invention provides a wrapping machine which enables the simultaneous wrapping of two loads or, alternatively, the wrapping of one load and the simultaneous preparation of another load for wrapping.
  • the invention offers a solution which enables speeding up the wrapping process with respect to the prior art solutions and improving the efficiency of a wrapping machine operator's work.
  • the solution according to the invention is preferably made up of a base, two side- by-side arranged support structures attached to the base, an arm structure attached rotatably to each support structure, as well as film dispensing elements mounted movably on the arm structures.
  • Each support structure is preferably made up of a vertically extending support section to whose top end zones are attached support sections extending in horizontal plane and preferably in opposite directions.
  • the arm structures are preferably made up of an arm section, which extends in horizontal plane and is attached from one end to the support structure and from other end to a top end of the vertically downward extending arm section.
  • the film dis- pensing elements comprise preferably a roll of film web, as well as means for mounting the roll of film web in a manner movable along the arm structure's vertically extending arm section.
  • the solution of the invention comprising two wrapping stations on the opposite sides of a wrapping machine, provides a balanced wrapping machine, which ena- bles a substantial reduction in the size of a base used for supporting the wrapping machine. This provides a major facilitation regarding the mobility of a wrapping machine of the invention, as well as a reduction of the storage space required.
  • the wrapping machine according to the invention has its base preferably provided with recesses, notches or the like, into which can be inserted a fork-shaped lifting element, such as the lifting fork of a forklift or a pallet truck, for lifting the wrapping machine off the floor level and for moving it.
