Definitions

  • This invention refers to a method and the relevant equipment, for achieving stabilising ventilated coverings for palletised loads, with plastic film.
  • One of such methods entails covering the palletised load with a plastic film, like a large cover.
  • Said cover can be heat shrunk plastic, heated so it shrinks and adheres perfectly to the palletised load, or it can be a cover made with an elastic material that expands when it is being fitted, adhering elastically to the palletised load while yet another method entails wrapping the palletised load with an extensible plastic strip, pulled taut, wrapping it tightly.
  • the second method can be done using a wrapping machine that comprises a reel of film moving vertically and which wraps the plastic film helicoidally around the outside of the palletised load as it turns on a swivel platform; or, with a different wrapping machine whose reel of film moves both vertically and with a planetary motion around the palletised load that stays still.
  • the humidity in the air trapped inside the stabilising covering condensates on the surface of said containers which, getting wet, can deteriorate (i.e. bricks) or can wet other objects of the load or other packaging elements, damaging them.
  • pre-perforated covering materials are now used (heat shrunk wrapping, elastic wrapping or extensible film) to ensure natural aeration of the load with no condensation.
  • pre-perforated covering materials are more expensive (because they need perforating), less resistant compared to the usual, non perforated covering materials and afford less stability to the palletised load in general; pre-perforated material is preferred only when it is essential to avoid condensation, as mentioned above.
  • Document DE 195 03 927 discloses a procedure for producing ventilating holes on a foil hood covering stacked goods, wherein these ventilation holes are produced in the side walls or top of the foil hood by concentrated heat application, and more particularly by means of a plurality of nozzles which are arranged on a fixed station at a certain distance from the foil hood for ejecting in front of it jets of compressed and hot air, so as to soften and fuse the foil hood and thereby form the holes, in accordance with the preamble of claim 1.
  • the purpose of this invention is to solve the drawbacks of known techniques with a simple, rational and cost-effective solution.
  • this objective is attained with a method for achieving stabilising ventilated coverings for palletised loads using plastic film, and with a corresponding equipment having the steps and the features recited by the main independent claims.
  • the palletised load can be advantageously covered with the usual, non perforated covering materials that are more economical and resistant compared to pre-perforated materials.
  • the stabilising covering is applied by wrapping a plastic film around the palletised load several times and then all the layers on at least one side of the load are perforated simultaneously.
  • each aeration hole in the stabilising covering it is preferable to use a heat source that softens the stabilising covering, melting it locally.
  • each aeration hole has an edge thickened by a ridge of melted plastic which, as it cools, prevents the hole from expanding which would weaken the stabilising covering; this makes the film far more resistant to tears compared to a film that is perforated mechanically.
  • the stabilising covering is applied by wrapping a plastic film around the load several times, the layers thus obtained are sealed together by the melted (and hardened) edges of the holes.
  • the stabilising covering is not weakened by the aeration holes as is the case if perforation is simply mechanical but, to the contrary, the sealing of said layers renders the whole wrapping stronger and the plastic film cannot unwind when the load is being handled.
  • the invention also makes an equipment available for perforating the stabilising covering of palletised loads, achieved with plastic film.
  • Said equipment comprises at least one mobile supporting structure that alternately approaches and moves away from the palletised load and which has a plurality of perforating punches, each one making a hole in said covering of the palletised load.
  • each one of said perforating punches has a heatable head that softens the stabilising covering locally so that, by means of a mechanical action, the perforating punch can then perforate said stabilising covering.
  • the heat of the heatable head also seals said layers together, improving the wrapping of the palletised load.
  • the perforating equipment includes means to stop the supporting structure when the latter, as it approaches the palletised load, reaches a set distance from the palletised load, allowing the perforating punches to make the holes in the stabilising covering.
  • said stopping means include a proximity sensor integral with the supporting structure and which, as it touches the palletised load, causes the supporting structure to stop.
  • the approaching movement of the supporting structure is not constant but can adapt effectively and automatically to the different dimensions of palletised loads and to their position in relation to the perforating equipment.
  • the perforating punches are fixed to the supporting structure through securing means so their position can be varied on the structure.
  • the aeration holes can be made in the stabilising covering where there is no risk of damaging the load under it like, for instance, in gaps between one object and another as in the case of non-continuous loads such as bottles or the like.
  • the supporting structure oscillates on a rotational axis orthogonal to its direction of movement, preferably according to a horizontal axis, fitted with a pair of stop elements on sides opposite said rotational axis, their job being to go against the palletised load when the supporting side reaches the forward position.
  • the supporting structure can always place itself parallel to the side of the palletised load it is facing and, therefore, position the perforating punches correctly in relation to the stabilising covering.
  • the enclosed figures illustrate an equipment that makes aeration holes in the stabilising covering, obtained by wrapping palletised loads P with an extensible plastic film.
  • said equipment configures as a perforation station 1 of an industrial packing line, to be placed downstream the palletised loads P wrapping station; it could, however, also be used in the actual wrapping station and start working straight after the wrapping machine so the palletised load P needs no further handling.
  • the station 1 comprises a conveyor device 2 fitted with three sliding belts 20 on which the palletised loads P stand - their job being to move the loads in a straight feeding direction A - and a perforating machine 3 on the side of said conveyor device 2.
  • the perforating machine 3 consists of a fixed base 30 on which the sliding frame 31 is mounted which, operated by a jack 32, moves with a reciprocating motion in a straight line B orthogonal to the feeding direction A of the palletised loads P.
  • a substantially vertical supporting side 33 on the front of the frame 31, that is, on the side facing the conveyor device 2 and which follows the movement of the frame 31, can selectively approach or move away from the palletised loads P.
  • said supporting side 33 is hinged to the frame 31 so it can oscillate in relation to the latter, turning around a rotational axis C, horizontal and orthogonal to the direction of movement B of the frame 31; said oscillation is limited by a pair of opposing stops 42 positioned on an intermediate cross bar 43 fixed to the frame 31 (see Figs. 2 and 4 ).
  • the supporting side 33 comprises a perimeter frame 34 stiffened by a pair of horizontal beams 35 and closed at the rear by a panel 36, plus a set of vertical rods 37 with their ends connected to the top and bottom of said perimeter frame 34.
  • a row of perforating punches 4 is fixed to each vertical rod 37 projecting from the supporting side 33, facing the palletised loads P.
  • said perforating punches 4 are elongated elements, each fitted with a heatable head 40 with a controlled and adjustable temperature (using a thermostat). They are pushed against the stabilising covering of the palletised loads P to make the hole.
  • Said perforating punches 4 can however be different like, for instance, a cutter or perforating head.
  • the ends of the vertical rods 37 are secured to the perimeter frame 34 by sliding joints 38 that engage inside the horizontal guides 39 fixed to the top and bottom of the perimeter frame 34 so that the rows of perforating punches 4 can alternately approach/move away; in addition, said perforating punches 4 are, in turn, fixed to the vertical rods 37 with clamp devices 41 so their reciprocal vertical distance can be varied.
  • the supporting side 33 also includes a pair of horizontal stop bars 5 on the opposite side of the horizontal axis hinge C that connects the supporting side 33 to the frame 31.
  • stop bars 5 The purpose of said stop bars 5 is to go against the palletised load P as the supporting side 33 approaches so as to define the correct position of the perforating punches 4 in relation to the stabilising covering and to make the supporting side 33 oscillate around the rotational axis C if its inclination does not coincide with that of the side of the palletised load P facing it.
  • stop bars 5 are connected to the perimeter frame 34 of the supporting side 33, each one by means of a pair of sliding joints 50 that, engaging in a vertical guide 51, make it possible to adjust their position and reciprocal distance.
  • each stop bar 5 supports its own proximity sensor 52, preferably a microswitch that, when it comes into contact with the palletised load P, emits an electrical signal that is sent to the control means (not shown) of the perforating machine 3.
  • proximity sensor 52 preferably a microswitch that, when it comes into contact with the palletised load P, emits an electrical signal that is sent to the control means (not shown) of the perforating machine 3.
  • both microswitches 52 emit said signal
  • the supporting side 33 stops instantly and retracts from the palletised load P.
  • a timer can be operated which, appropriately set, makes it move back after a certain length of time, sufficient for the heatable heads 40 of the perforating punches 4 to make the holes in the palletised load's P wrapping.
  • the position of the perforating punches 4 on the supporting side 33 needs to be adjusted according to the form, type and layout of the load on the pallet so said punches 4 cannot accidentally damage the load during perforation.
  • the palletised loads P wrapped previously with the extensible plastic film are positioned on the conveyor device 2 one at a time.
  • Said palletised loads P are normally parallelepiped in shape and, therefore, positioned on the conveyor device 2 so two opposite sides are parallel with the feeding direction A.
  • the conveyor device 2 moves the palletised loads P forward intermittently so that for each feeding phase a palletised load P is in the perforating position, that is, in a suitable position for the perforating machine 3.
  • the perforating position for the palletised load P is in front of the perforating machine 3 so that one of its opposite sides, parallel with feeding direction A, faces the supporting side 33 and, hence, the perforating punches 4 projecting from the latter.
  • the jack 32 operates the frame 31 so that said supporting side 33 makes an approach stroke towards the palletised load P.
  • the perforating punches 4 move close the stabilising covering, it is locally softened by the heatable heads 40 so that when the supporting side 33 moves forward again, the perforating punches 4 can mechanically perforate the film.
  • the heat of the heatable head 40 also seals said layers together locally, strengthening the wrapping of the palletised load P even more; in addition, said head also creates an edge of melted plastic material around the hole that, cooling down, strengthens it.
  • the jack 32 is then operated again, retracting the frame 31 and moving the supporting side 33 away for a new feeding phase of the conveyor device 2 that moves the palletised load P away with its perforated wrapping, placing a new palletised load P in the perforating position.
  • the perforating equipment could be made of a plurality of perforating machines 3 that make aeration holes on several sides of the palletised load P simultaneously.
  • the perforating station 1 could comprise two perforating machines 3, opposite each other and positioned on opposite sides of the conveyor device 2, working simultaneously on both sides of the palletised load P, parallel with the feeding direction A.
  • the supporting side 33 of perforating machine 3 could have just one vertical row of perforating punches 4 and the feeding system could be made to move the palletised loads P forward in steps shorter than their length.
