Definitions

  • EP-A-1060988 discloses a device for overpacking a load palletized by means of a cover prepared from a bellows sleeve rolled flat on a reel of storage.
  • a gripper robot has a motorized accumulator roller on which is wound a part of the sheath, a roller transfer arm to the stuffing station, and a mechanism spreading the cover during the downward movement around the charge.
  • the sheath previously welded in the transverse direction is maintained in vertical position with bellows solicited by an organ positioner, which is fixed and arranged with the coil in the vicinity of the ground.
  • the robot transfer arm is carried by a mobile slide in vertical translation on the frame.
  • the robot's arm is thus animated by a first horizontal movement of translation during the transfer, and a second downward movement for prepare the cover by welding and cutting after wrapping around the roll accumulator.
  • This second vertical movement of the arm is indispensable, being given that the positioner member of the sheath is fixed. This combined movement of robot lengthens the time of preparation and removal of the cover, and limits packaging rates of the machine.
  • EP-A-395919 relates to a machine for packing a load palletized with heat-shrinkable film, comprising four bars verticals equipped with grippers film up and down in the frame, an annular retraction furnace, a pair of horizontal struts and two trolleys that can move horizontally along the sleepers.

  • EP 1106507 mentions a packaging machine, in which the heat-sealed connection instead of being arranged at the top, is oriented downwards. he it is then necessary to turn upside down. The positioner and the welder remain in the lower part. Such a device is suitable for loads low heights, but not for high heights.
  • a first object of the invention is to improve the preparation process and removal of a cover on a palletized load, to accelerate the cycles packaging and increase production rates.
  • the organ positioner is moved to an intermediate waiting position just before said upper position of the film in the accumulator element. This results in a time saving corresponding to the duration of the rise stroke of an organ positioner between the low position and the intermediate waiting position.
  • a second object of the invention is to provide a machine for the implementation of form and removal of a packaging cover on a palletized load, allowing high production rates, and can use indifferently a sheath heat-shrinkable or stretchable plastic.
  • the machine comprises a transfer and accumulation device comprising a accumulator element on which is wound a portion of the sheath, and a mechanism of separation of the open end of the sheath after transfer to the padding station.
  • the positioner member is movable in height in the preparation station by being coupled to an actuator, so as to move the sheath between a low standby position and a high position engaging the heat-sealed connection in the accumulator element.
  • the transfer and accumulation device is pivotally mounted on an axis vertical of an actuating arm to position the heat-sealed connection parallel or perpendicular to the largest face of the load.
  • the organ positioner is guided in vertical translation between the two low and high by a guide rod or slide secured to a support.

  • the packaging sheath 17 is formed by a plastic film with double V gussets, and folded flat after winding around each cylindrical coil 11, 12. This type of sheath is described in detail in EP-A-1060988. She is then unrolled, passes over guide rollers 18, 18a, and is maintained in vertical position with the bellows solicited by the organs positioners 13, 14. Previously, the middle portion of each sheath 17 has been welded transversely to its free end to obtain a watertight bottom through forming a heat-sealed bond 19.
  • the casing 17 with bellows can also be replaced by a simple tubular sheath without gussets, and also folded flat on the coils 11, 12.
  • the film of the sheath 17 may be of heat-shrinkable plastic or stretchable plastic.
  • Figures 3 to 9 show an application with a heat-shrinkable film, while Figures 10-18 illustrate another application with stretch film.
