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.
  • these show a packaging machine in extensible film of products fed forwards in groups in pairs, such as bottles or other objects 11.
  • the groups of products can naturally be reduced to a single product.
  • the products such as bottles or other objects 11, are arranged in two adjacent, aligned and continuous rows, that are separated into a single product or into groups of products moved forwards up to a conveyor belt 12 for feeding the packaging machine.
  • An ordering machine 13 receives one group of products after another, for example comprising two rows of adjacent bottles 11, from said conveyor belt 12, and keeps them thus ordered and spaced, up to a first ring winding unit 14.
  • the first ring winding unit 14 is then followed by a second ring winding unit 15, opposite the first unit 14, which effects a winding in an opposite direction with respect to the first winding unit 14 to produce a continuous packaging or bundle containing products or groups of products, separate and spaced.
  • the second winding unit 15 is in turn followed by a cutting unit 16 of the continuous packaging of the groups of products 11, wound in film of extensible plastic material 17, forming a final packaging 18.
  • said ordering unit 13 comprises a frame 20 carrying two belts 21, 21' ring-wound around end pulleys arranged on respective vertical axes 22, 23, one of said axes 22 being motorized by means of a toothed belt 24 driven by a gearmotor 25.
  • the belts 21, 21' are toothed by means of spaced dowels 26 protruding from one belt 21 towards the other belt 21' opposite and facing the same.
  • one belt 21 is spaced with respect to the other opposite belt 21' by a dimension equal to at least two adjacent bottles or products 11.
  • a lower conveyor belt 27 supports the various pairs of bottles 11 moving forwards.
  • Three pairs of bottles 11 for each group are positioned, for example, between the rotation axes 22, 23 of the two belts 21, 21', but the number can vary as required.
  • Each pair of bottles 11 is arranged between two pairs of subsequent dowels 26 of each belt 21, 21', said dowels 26 being inserted in the space left by the shape of the bottles 11 exerting a withholding action in a reciprocal position also thanks to the collaboration of the lower conveyor belt 27.
  • the dowels 26 of the pair of belts 21, 21' can be advantageously constrained to the belt 21, 21' at a different relative distance in relation to the size of the single product or bottle 11 and to the free space between each group of products or bottles 11.
  • the dowels 26 of a first belt 21 naturally collaborate with the dowels 26 provided on the second opposite belt 21', which is facing and in phase with the first belt 21.
  • Sensors 28 are positioned at the inlet and outlet of said ordering unit 13 to verify whether the bottles 11 of each group are present and if they are missing, they stop the advance movement.
  • the advance rate is modulated in relation to the filling degree of the line so as to avoid stoppages as much as possible.
  • the ordering unit 13 at the inlet of the packaging machine determines the velocity for all the units downstream and for the velocity of the winding units 14 and 15, which must move at a synchronized rate.
  • the conveyor belt 29 connects the ordering unit 13 with the subsequent first winding unit 14. Pairs of side guiding bars 30, also cantilevered from the frame 20 and arranged laterally above the conveyor belt 29, keep the succession of pairs of bottles 11 of the group leaving the ordering unit 13, compact and ordered up to the first winding unit 14.
  • the conveyor belt 29, arranged cantilevered from the frame 20, can provide on its surface, a series of holes 29' which on a section of the upper surface receive air and form an air cushion to facilitate the sliding of the film when it slips off the conveyor belt 29 before moving forward and passing into the subsequent winding unit.
  • the first winding unit 14 comprises a frame 31, positioned astride with respect to the row of pairs of bottles 11 of the group moving forward, which, on opposite sides, supports two ring winding machines 32, the same but opposite.
  • Each ring winding machine 32 comprises a ring or fifth wheel 33 which rotates with respect to guiding rollers 34, positioned on the frame 31.
  • Said ring 33 is arranged on a plane perpendicular to the advance direction of the bottles 11 in groups.
  • a gearmotor 35 integral with the frame 31 controls the rotation of the ring 33 by means of a command-friction roller 36.
  • a reel-holder 37 for a reel 38 of film of extensible plastic material 17, is assembled integral with each ring 33.
  • a support 39 of a rubberized tensioning roller 40 and a pair of return rollers 41 for the film 17 are associated with said reel-holder 37.
  • the tension of the film 17 being unwound can be regulated by means of a brake (not shown) which acts directly on said rubberized tensioning roller 40.
  • a brake (not shown) which acts directly on said rubberized tensioning roller 40.
  • the rotating ring 33 rotates with a variable rotation rate to allow the deposition of the correct quantity of film in relation to the advance rate of the bottles 11 in groups.
  • the second ring 33 is activated to rotate with a full reel 38. The first ring 33 is stopped and the exhausted reel 38 can be substituted without stopping the whole machine.
  • two conveyor belts a lower belt 42 and an upper belt 43 with separate motorization, are provided inside the frame 31 of the winding unit of the bottles 11 of the groups, in the area between the two rotating rings 33.
  • the conveyor belts 42 and 43 are conceived for entraining the bottles in groups from the first to the second ring 33 of the first winding unit 14 or in any case forwards, passing inside the frame 31.
  • the frame 31 at the outlet of the first winding unit, in the advance direction of the bottles 11, provides an arrangement identical to that at the outlet of the ordering unit 13.
  • This arrangement is provided either simply for the support and advancing of the partial packaging produced by the ring winding machine 32 at the inlet of this winding unit or for supporting the bottles of the groups when they are being wound in the film effected with the second ring winding machine which also forms part of this winding unit 14.
  • a conveyor belt 29 is provided, which is arranged cantilevered and extending from the frame 31, according to the advance direction of the bottles in groups, connecting the first winding unit 14 to a connection module 44 with the subsequent second winding unit 15.
  • pairs of side guiding bars 30 are provided, also cantilevered from the frame 31, which keep the succession of pairs of bottles 11 of the groups leaving the first winding unit 14, compact and ordered.
  • connection module 44 provides, in a frame 49, two conveyor belts spaced apart and superimposed, a lower belt 45 and an upper belt 46, with separate motorization, and two pairs of side guiding bars 30.
  • An upper motorization and a lower motorization are in fact provided, effected by means of pairs of toothed wheels 47, wherein a toothed wheel for each pair is actuated by a gearmotor 48.
  • Said belts 45 and 46 are conceived for entraining the bottles in groups wound with the film of the first winding unit 14, forwards and correctly positioned.
  • connection module 44 in the advance direction of the bottles 11, an identical arrangement is provided as that at the outlet of the ordering unit 13 and the first winding unit 14.
  • a conveyor belt 29 is in fact provided, which is arranged cantilevered and extending from the frame 49, connecting the connection module 44 to the second winding unit 15 and also two pairs of side guiding bars 30, also cantilevered from the frame 49, which keep the partially wound advancing pairs of bottles 11 of the single groups, compact and ordered.
  • the side cutting device 51 provides a portal 56 containing two vertical side blades 57 movably positioned on horizontal guides 58 for moving forwards and backwards.
  • the two vertical side blades 57 can be moved towards and away from the plastic material of the continuous packaging wound around the groups of bottles 11 to effect a cutting on two vertical sections of said continuous packaging on opposite sides of said continuous packaging or bundle close to the terminal areas of the groups of bottles.
  • the vertical blades 57 are operatively connected to resistances which heat them, operating with a hot cut or in any case with alternative systems such as ultrasounds, etc.
  • the portal 56 is positioned astride on the continuous packaging or bundle of groups of products 11 that is moving forwards in the packaging machine.
  • Figures 14 and 15 respectively show sectional views in correspondence with the upper and lower cutting device 52 of the cutting unit 16 with the upper 62 and lower 62' horizontal blades and side cutting device 51 with the vertical side blades 57 in an operational position acting on the film of plastic material that is being wound around the groups of products.
  • the reciprocal distance d between the two portals 56 and 61 of the two side 51 and upper and lower 52 cutting devices is variable and adjustable in the setting phase of the machine with both a variation in the dimensions of the bottles 11 being packaged and above all in the quantity of bottles 11 of the single group required in the final packaging to be obtained.
  • adjustable struts/rods 68 connect the two portals 56 and 61 of the two cutting devices 51 and 52 so that the reciprocal distance can be varied and regulated.
  • 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.
  • bottles 11 or different containers to be packaged into packagings having a predetermined 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 11 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 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.
  • 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.
