Definitions

  • the present invention refers to a method and the relative plant for wrapping palletised loads.
  • palletised loads are generally covered with a stabilising wrapping that immobilises the loads on pallet, leaving said wrapping on for transporting as it guarantees against the risk of falling or tipping over.
  • Wrapping is generally carried out using automatic or semi-automatic plants.
  • a widely used wrapping plant is the one with a covering film reel moving machine and a swivel platform on which the palletised load is deposited for wrapping.
  • the moving machine moves the reel of film in a vertical direction while simultaneously wrapping the covering film on the palletised load as it turns on the swivel platform.
  • the swivel platform and reel moving machine are part of an automatic conveyance line which sees to depositing the palletised loads one after the other on the swivel platform and moving them away from it once wrapped.
  • said conveyance line comprises transport means for placing the palletised loads on the swivel platform and accessory devices for preparing each palletised load for wrapping.
  • the conveyance line generally comprises means for applying a covering element on each palletised load, usually a sheet of plastic, and other means for pressing said covering element on the palletised load as it is turning on the swivel platform.
  • moving palletised loads that are not yet stabilised is a difficult job and must be done at rather slow speeds and accelerations if there is to be no falling or tipping over.
  • Another setback concerning said down times is the time needed for the accessory devices to get the palletised loads ready for the preparatory operations.
  • the main aim of this invention is to find a method and a plant for wrapping palletised loads that will get around the above mentioned drawbacks with a simple, rational and cost-effective solution.
  • the current plant for wrapping palletised loads characterised by the fact that it comprises at least one first swivel platform to receive a palletised load and to make it turn around a vertical rotational axis, a second swivel platform to receive a palletised load and to make it turn around a vertical rotational axis, and a covering film reel moving machine to wrap with said covering film a palletised load that is turning either on said first swivel platform or on said second swivel platform, said moving machine being designed to work, alternately, a palletised load deposited on the first swivel platform and a palletised load deposited on the second swivel platform.
  • a plant for wrapping palletised loads comprising a first swivel platform 2 and a second swivel platform 3 has been generally designated by reference numeral 1.
  • Each swivel platform 2 and 3 is for holding a palletised load C to wrap, and is designed to turn it around a substantially vertical rotational axis.
  • each swivel platform 2 and 3 features a top standing surface, substantially flat, to hold the palletised load C.
  • the standing surface consists of a motorised roller conveyor 4 along which the palletised load C moves forward until it reaches a substantially central position on the relative swivel platform 2 and 3.
  • a moving machine 5 for a reel 6 of a covering film 6a is positioned between the first swivel platform 2 and the second swivel platform 3.
  • the moving machine 5 is designed to work with both swivel platforms 2 and 3 to move the reel 6 vertically so the covering film 6a can be wrapped on the palletised loads C as they are turning on the swivel platforms 2 and 3.
  • the moving machine 5 is able to work alternately on a palletised load C already deposited on the first swivel platform 2 and on another palletised load C already deposited on the second swivel platform 3.
  • the moving machine 5 comprises a jointed arm 7 featuring a working head 8 on its free end that supports the reel 6.
  • the jointed arm 7 is hinged to a fixed base 9 on a vertical axis so it can rotate around said axis to bring the reel 6 close to the first swivel platform 2 or, alternately, to the second swivel platform 3.
  • the moving machine 5 is of the automatic working head 8 changeable type.
  • the plant 1 comprises a deposit magazine 10 for the interchangeable working heads 8 located where it can be accessed by the jointed arm 7 of the moving machine 5.
  • the deposit magazine 10 is equipped with a set of supporting structures 11 for housing the working heads 8.
  • the moving machine 5 automatically releases the working head 8 onto an empty supporting structure 11 and collects a new working head 8 from the deposit magazine 10 that has a reel 6 ready to use.
  • This changing-over operation normally only takes about twenty seconds.
  • the moving machine 5 is of the known type and therefore will not be described further herein.
  • the swivel platforms 2 and 3 are served by a first automatic conveyance line 12 and by a second automatic conveyance line 13 respectively.
  • Each conveyance line, 12 and 13 is designed to automatically place a palletised load C for wrapping on the relative swivel platform 2 and 3, and to move the wrapped palletised load C away.
  • Each conveyance line 12 and 13 features transfer means that move a palletised load C towards the relative swivel platform 2 and 3, place it on the platform and later move it away from the platform.
  • such transfer means consist of a motorised inlet roller conveyor 14 positioned upstream of the corresponding swivel platform 2 and 3, a motorised roller conveyor 4 on the actual platform and a motorised outlet roller conveyor 15 positioned downstream of the swivel platform 2 and 3.
  • both the first and second conveyance lines 12 and 13 feature the applicator means 16 that place a covering element E, such as a sheet of cardboard or the like, on each palletised load C in preparation for wrapping.
  • a covering element E such as a sheet of cardboard or the like
  • the conveyance lines 12 and 13 are equipped with their own pressing devices 17 that lower to press the palletised load C which is on the first swivel platform 2 or, respectively, on the second swivel platform 3, the purpose being to keep it stable while wrapping.
  • the pressing devices 17 are mounted on corresponding supporting columns 18 and slide vertically so they come into contact with the covering element E placed on top of the palletised load C.
  • the plant 1 features a control and operating system, not illustrated in detail in the figures, that co-ordinates the operation of the moving machine 5, of the conveyance lines 12 and 13 and of the pressing devices 17.
  • This control and operating system works in such a way that while the moving machine 5 is working on a palletised load C deposited on the first swivel platform 2, the second conveyance line 13 moves a previously wrapped palletised load C away from the second swivel platform 3 and places a new palletised load C on it to be wrapped and on which a pressing device 17 lowers, and vice versa.
  • the operation of plant 1 comprises, first of all, the phases allowing to deposit one palletised load C at a time on the first and second swivel platform 2 and 3 respectively.
  • Such phases consist of moving the palletised loads C along the motorised inlet roller conveyors 14, applying the covering elements E on the palletised loads C through the applicator means 16, placing the palletised loads C on the swivel platforms 2 and 3 and then pressing the covering elements E on the palletised loads C through the lowering of the pressing devices 17.
  • the palletised loads C placed on the platforms 2 and 3 are then wrapped alternately by means of the co-ordinated movement of the reel 6, carried by the moving machine 5, and the rotation of the palletised load C placed on the swivel platforms 2 and 3.
  • each palletised load C is wrapped, it is moved away from the relative swivel platform 2 and 3.
  • a previously wrapped palletised load C is moved away from the second swivel platform 3 and a new palletised load C is deposited in its place, ready for wrapping, and vice versa.
