Definitions

  • the present invention relates to a packaging method and machine in extensible film of products fed in groups.
  • a film made of heat-shrinkable plastic material is currently most commonly used. This film is wound around the product or group of products, then welded and cut to size and subsequently treated in a heat-shrinking oven which stabilizes the packaging thus produced, stably holding the products.
  • This technique involves a certain cost for plastic material having a certain thickness, a cost due to the energy used for the heat shrinking, in addition to a plant cost requiring the presence of a packaging machine and a relative heat-shrinking oven associated with the same. There is also a further increase in costs due to the considerable times for obtaining the finished packaging of products subjected to heat-shrinking.
  • an extensible plastic film is used for the packaging, which is spirally wound around the product or group of products that are moved forward in a horizontal direction.
  • the products are divided into groups and selectively wound in correspondence with a winding unit.
  • a reel of extensible plastic film is caused to rotate around the products advancing along a conveyor belt or roller and when the winding has been completed, the packaging thus obtained is discharged.
  • a reel-holder trolley is provided which is moved along a circular guide on a plane perpendicular to the advance direction around the products being packaged.
  • Packaging in film made of extensible plastic material eliminates the necessity of a heat-shrinking oven and the energy costs associated therewith, it allows the use of a thinner film with a cost reduction, but at present is not satisfactory due to the times for reaching the final packaging.
  • a further problem which is strongly felt relates to the change of reel with its exhaustion which involves stoppages of the whole machine.
  • WO 2015/040565 discloses equipment used for the packaging of bottles with a thin film made of extensible plastic material which is spirally wound around bottles fed consecutively in continuous, said equipment having an entrainment station comprising pairs of conveyor belts and also pairs of disc plates.
  • the general objective of the present invention is to provide a packaging method and machine in extensible film of products, that is able to solve the drawbacks of the known art described above in an extremely simple, economical and particularly functional manner.
  • a further objective of the present invention is to provide a packaging method and machine that can function practically in continuous, eliminating any type of stoppage in the packaging phase for reel change or cutting of the finished product.
  • Another objective of the invention is to provide a packaging machine of products which, by using an extensible film, also reduces costs relating to the packaging material.

  • the two horizontal blades 62 , 62 ′ are operatively subjected to resistances that heat them, operating with a hot cut or in any case with alternative systems such as ultrasounds, etc.
  • the two horizontal blades 62 , 62 ′ are driven in this movement by a double crank mechanism 64 , 64 ′, upper and lower, actuated by a single motor 65 .
  • the lower blade 62 ′ in its forward and backward, upward and downward movement moves in an omega-shaped loop 66 formed in the belt 55 , wherein said omega-shaped loop can be moved together with the slide 53 and with the upper and lower cutting device 52 .

  • the side blades 57 in an operational position act on the film, passing halfway through the whole film of plastic material, which envelops the groups of products, in order to produce the above-mentioned continuous packaging or bundle, so as to cut it transversally.
  • Said cutting unit 16 ′ can provide various devices 51 ′ in order to accelerate the separation operations of the packagings, increasing the productivity.
  • a packaging method in extensible film of products 11 fed forwards in groups, for example in pairs of adjacent products is in fact implemented.
  • Said method comprises, in succession, a step for ordering two continuous rows of said adjacent products 11 that form a group having a selected number and keeping the bottles thus ordered.
  • This is followed by a step for feeding and passing the products thus ordered into a first ring winding unit 14 of extensible film and winding the groups of products 11 in a first film.
  • Said winding is effected in a first rotation direction forming a continuous packaging or bundle of groups of products.
  • the groups of products, already wound in the first winding unit with a first film is then moved forwards and fed to a second ring winding unit 15 of extensible film. Said winding is effected in a second film in a second rotation direction opposite to the first rotation direction thus forming a continuous packaging or bundle of groups of products with two layers of film wound in opposite directions.
  • the continuous packaging or bundle is subsequently moved forwards and fed into a cutting unit 16 , which moves in synchrony with the continuous packaging or bundle.
  • the cutting unit cuts the continuous packaging or bundle of groups of products transversally into single packagings of the groups of products 11 .
  • the packaging method provides that the movable cutting unit 16 cuts the continuous packaging or bundle of the groups of products by means of a transversal perimetric cut.
  • the packaging method also effects the step of selectively and alternately winding the products in the extensible film in the two ring winding units 14 , 15 by means of one of two ring winding machines 32 provided for each of the two ring winding units 14 , 15 thus effecting a continuous winding also in the exhaustion phase of the film in at least one of the two ring winding machines 32 provided for each of the two ring winding units 14 , 15 .
  • bottles 11 or different containers to be packaged into packagings having a pre-determined size and quantity to form a group are fed consecutively in compacted pairs on two aligned and adjacent rows.
  • the groups of bottles 11 thus arranged are moved forwards up to a conveyor belt 12 for feeding the packaging machine as far as the inlet of the ordering unit 13 .
  • a correct and constant reciprocal arrangement of the bottles 11 of each group is obtained in this ordering unit 13 , thanks to the presence of the two belts 21 , 21 ′ with dowels 26 facing and protruding from one belt 21 towards the other opposite facing belt 21 ′.
  • the two continuous rows of bottles of each group therefore acquire an absolutely uniform arrangement before being fed to the rest of the machine.
  • the groups of bottles thus ordered and arranged are sent into the first ring winding unit 14 , in which, for example, one of the two ring winding machines 32 is active.
  • the plastic film of the reel of this ring winding machine 32 is caused to rotate and to be wound around the single group of bottles 11 moving forward on the conveyor belt 29 and between the pairs of side guiding bars 30 .
  • a continuous bundle of groups of pairs of bottles is thus obtained, moving forwards with a certain tension of the film thanks to the specific means provided and previously described.
  • the groups of bottles 11 thus wound leave the first winding unit 14 and, passing onto a further conveyor belt 29 , they reach the connection module 44 towards the subsequent second winding unit 15 .
  • the feeding is favoured by the presence of two conveyor belts 42 and 43 .
  • Further conveyor belts spaced apart and superimposed 45 and 46 are provided in the connection module 44 to favour the forward movement of the continuous packaging or bundle of groups of pairs of bottles 11 , at the same time keeping them well positioned.
  • Said continuous packaging or bundle of spaced groups of bottles 11 thus formed with crossed layers of film continues to move forwards favoured by the presence of two conveyor belts 42 and 43 provided inside the second winding unit 15 and further conveyor belts 45 and 46 provided in a second connection module 44 positioned before the inlet to the cutting unit 16 .
  • the continuous bundle then passes onto the conveyor belt 55 positioned in the cutting unit 16 which supports and accompanies the continuous packaging or bundle containing the groups of bottles 11 during the subsequent entire cutting step.
  • the slide 53 containing the two side 51 and upper and lower 52 cutting devices moves to correlate with the advance rate of the continuous bundle.
  • the cutting is effected by the two devices when the relative rate between the slide 53 and bundle containing the groups of bottles 11 is zero.
  • the vertical side blades 57 of the side cutting device 51 act on a section of the continuous bundle at the ends of the groups of bottles, whereas the two upper 62 and lower 62 ′ horizontal blades of the upper and lower cutting device 52 act on a different section of the continuous bundle again at the ends of the groups of bottles 11 .
  • the completion and separation of the finished packaging is effected when, as the continuous bundle continues to move forwards, the slide 53 has brought the cutting devices 51 and 52 back and has been reactivated in the advance direction of the continuous bundle returning to the same advance rate as the continuous bundle. It is in this situation, in fact, that the two cutting devices 51 and 52 re-operate and effect the respective vertical perimetric and horizontal cuts on the bundle in those sections in which, however, horizontal and vertical perimetric cuts had been previously effected, completing the perimetric cutting of the continuous packaging containing groups of bottles and separating the single packaging.
  • This cutting unit 16 has been described, but another different cutting unit can be identically used without providing a packaging machine in extensible film of products fed in continuous which is different from that of the present invention.
  • An important feature of the machine of the present invention lies in the possibility of effecting a continuous winding of groups of pairs of bottles or products being packaged without any interruption. This is possible thanks to the provision of two ring winding machines 32 in each winding unit, the same but opposite, that operate selectively and alternately according to whether or not the film of the respective reel is running low.
  • the possibility of always having winding film in one ring winding unit or in the other of each winding unit avoids stoppages of the machine and allows the exhausted reel of one ring winding machine to be substituted when the other ring winding machine is operating. This is obtained by means of specific sensors which detect the approaching end of the film of a reel and which allow the advance starting of the second ring winding machine before the film of the first ring winding machine has terminated.
  • a method and a machine are in fact provided for the packaging of products fed in continuous, which does not require any stoppage in the case of exhaustion of the winding film and packaging.
  • More than one cutting unit coupled with the winding units can also be provided, for example, with an increase in the hourly productivity. This is possible thanks to the high speeds that can be reached with the winding units and due to the fact that no stoppage is required for intervening on the film being fed for the winding.
  • the velocity of this machine is also possible due to the fact that the cutting is effected peripherally with minimum movements of the blades which have extremely limited intervention times.
