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.

- 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 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.
Description
- The present invention relates to a packaging method and machine in extensible film of products fed in groups.
- In the packaging field of various types of products such as, for example, bottles, boxes having varying formats, etc., 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.
- Alternatively, 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. In said 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. In this packaging unit, 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. It can be immediately seen that this technique requires continuous stoppages for the formation of each packaging with problems associated with the connection of the head of the film to the products to be packaged and cutting of the packaged product.
- Furthermore, the packaging requires times that are certainly not short due to this alternative movement. Packaging in film made of extensible plastic material, on the other hand, 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 structural and functional characteristics of the present invention and its advantages with respect to the known art will appear even more evident from the following description, referring to the enclosed schematic drawings, which show an embodiment example of the same invention. In the drawings:

figures 14 and15 show sectional views in correspondence with the cutting unit with the upper and lower blades and side blades respectively, in an operating position acting on the film of plastic material that is enveloping the products; -
figures 16 and17 are a raised side view showing an alternative embodiment of a cutting unit forming part of the packaging machine and a sectional view in correspondence with the cutting unit offigure 16 with the side blades in an operating position acting on the whole film of plastic material that is enveloping the products. - With reference to the figures, these show a packaging machine in extensible film of products fed forwards in groups in pairs, such as bottles or
other objects 11. In a particularly simplified embodiment, the groups of products can naturally be reduced to a single product. - It should be noted that upstream of said machine, 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 aconveyor belt 12 for feeding the packaging machine. - An
ordering machine 13 receives one group of products after another, for example comprising two rows ofadjacent bottles 11, from saidconveyor belt 12, and keeps them thus ordered and spaced, up to a firstring winding unit 14. - The first
ring winding unit 14 is then followed by a secondring winding unit 15, opposite thefirst unit 14, which effects a winding in an opposite direction with respect to thefirst winding unit 14 to produce a continuous packaging or bundle containing products or groups of products, separate and spaced. Thesecond winding unit 15 is in turn followed by acutting unit 16 of the continuous packaging of the groups ofproducts 11, wound in film of extensibleplastic material 17, forming afinal packaging 18. - In the example shown, said ordering
unit 13 comprises aframe 20 carrying twobelts 21, 21' ring-wound around end pulleys arranged on respectivevertical axes axes 22 being motorized by means of atoothed belt 24 driven by agearmotor 25. Thebelts 21, 21' are toothed by means of spaceddowels 26 protruding from onebelt 21 towards the other belt 21' opposite and facing the same. In this example, onebelt 21 is spaced with respect to the other opposite belt 21' by a dimension equal to at least two adjacent bottles orproducts 11. Alower conveyor belt 27 supports the various pairs ofbottles 11 moving forwards. Three pairs ofbottles 11 for each group are positioned, for example, between therotation axes belts 21, 21', but the number can vary as required. Each pair ofbottles 11 is arranged between two pairs ofsubsequent dowels 26 of eachbelt 21, 21', saiddowels 26 being inserted in the space left by the shape of thebottles 11 exerting a withholding action in a reciprocal position also thanks to the collaboration of thelower conveyor belt 27. Thedowels 26 of the pair ofbelts 21, 21' can be advantageously constrained to thebelt 21, 21' at a different relative distance in relation to the size of the single product orbottle 11 and to the free space between each group of products orbottles 11. - The
dowels 26 of afirst belt 21 naturally collaborate with thedowels 26 provided on the second opposite belt 21', which is facing and in phase with thefirst belt 21. -
Sensors 28 are positioned at the inlet and outlet of said orderingunit 13 to verify whether thebottles 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. Theordering unit 13 at the inlet of the packaging machine determines the velocity for all the units downstream and for the velocity of thewinding units - At the outlet of said
ordering unit 13, the pairs ofadjacent bottles 11 of each group, adjacent and one after another, advance on afurther conveyor belt 29 arranged cantilevered and extending from theframe 20, according to the advance direction of the bottles. Theconveyor belt 29 connects theordering unit 13 with the subsequentfirst winding unit 14. Pairs of side guidingbars 30, also cantilevered from theframe 20 and arranged laterally above theconveyor belt 29, keep the succession of pairs ofbottles 11 of the group leaving theordering unit 13, compact and ordered up to thefirst winding unit 14. - The
conveyor belt 29, arranged cantilevered from theframe 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 theconveyor belt 29 before moving forward and passing into the subsequent winding unit. - The
first winding unit 14 comprises aframe 31, positioned astride with respect to the row of pairs ofbottles 11 of the group moving forward, which, on opposite sides, supports tworing winding machines 32, the same but opposite. - Each
ring winding machine 32 comprises a ring orfifth wheel 33 which rotates with respect to guidingrollers 34, positioned on theframe 31. Saidring 33 is arranged on a plane perpendicular to the advance direction of thebottles 11 in groups. Agearmotor 35 integral with theframe 31 controls the rotation of thering 33 by means of a command-friction roller 36. - A reel-
holder 37 for areel 38 of film of extensibleplastic material 17, is assembled integral with eachring 33. Asupport 39 of a rubberizedtensioning roller 40 and a pair ofreturn rollers 41 for thefilm 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 rubberizedtensioning roller 40. In this way, during the winding process of the film around thebottles 11 of the groups, the rotatingring 33 rotates with a variable rotation rate to allow the deposition of the correct quantity of film in relation to the advance rate of thebottles 11 in groups. As already mentioned, there are advantageously tworings 33 for eachwinding unit 14; one rotates and the other is stationary during the operating phase. When thereel 38 positioned on thering 33 that is rotating, is running low, thesecond ring 33 is activated to rotate with afull reel 38. Thefirst ring 33 is stopped and theexhausted reel 38 can be substituted without stopping the whole machine. - This allows an operating continuity even when the film of one reel ends and the winding unit does not have to be stopped in order to replace the reel. It is in fact stated that when the film of one
winding ring 33 ends, theother ring 33 begins to operate, thus enabling the reel to be substituted without stopping the process. - It should also be noted that two conveyor belts, a
lower belt 42 and anupper belt 43 with separate motorization, are provided inside theframe 31 of the winding unit of thebottles 11 of the groups, in the area between the tworotating rings 33. Theconveyor belts second ring 33 of the first windingunit 14 or in any case forwards, passing inside theframe 31. - Furthermore, the
frame 31 at the outlet of the first winding unit, in the advance direction of thebottles 11, provides an arrangement identical to that at the outlet of theordering unit 13. This arrangement is provided either simply for the support and advancing of the partial packaging produced by thering 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 windingunit 14. Also in this case, in fact, aconveyor belt 29 is provided, which is arranged cantilevered and extending from theframe 31, according to the advance direction of the bottles in groups, connecting the first windingunit 14 to aconnection module 44 with the subsequent second windingunit 15. Also in this case, pairs of side guiding bars 30 are provided, also cantilevered from theframe 31, which keep the succession of pairs ofbottles 11 of the groups leaving the first windingunit 14, compact and ordered. - The
connection module 44 provides, in aframe 49, two conveyor belts spaced apart and superimposed, alower belt 45 and anupper 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 oftoothed wheels 47, wherein a toothed wheel for each pair is actuated by agearmotor 48. Saidbelts unit 14, forwards and correctly positioned. - It should be pointed out that, at the outlet of said
connection module 44, in the advance direction of thebottles 11, an identical arrangement is provided as that at the outlet of theordering unit 13 and the first windingunit 14. Aconveyor belt 29 is in fact provided, which is arranged cantilevered and extending from theframe 49, connecting theconnection module 44 to the second windingunit 15 and also two pairs of side guiding bars 30, also cantilevered from theframe 49, which keep the partially wound advancing pairs ofbottles 11 of the single groups, compact and ordered. - The second winding
unit 15, identically to the first windingunit 14, comprises aframe 31, positioned astride with respect to the row of pairs ofbottles 11 of the groups moving forward, wound with the film of the first winding unit. The second windingunit 15 also provides tworing winding machines 32 on opposite sides, which, in this case, are selectively actuated in relation to whether or not the reel is running low. It should also be noted that both of therings 33 of this second windingunit 15 rotate in an opposite direction with respect to the rings provided in the first windingunit 14. A second winding of thebottles 11 in groups with film is therefore effected, positioned above the film previously wound. An intersection of layers of film is thus obtained, which serves to stabilize the packaging when finished with superimposed layers of film and wound in two opposite rotation directions. -
Figure 8 shows the difference between the reciprocal arrangement between the reel-holder 37 and the reel offilm 38 of extensible plastic material and thesupport 39 carrying therubberized tensioning roller 40 and the pair ofreturn rollers 41 for thefilm 17. It should in fact be remembered that the film unwound from thereel 38 in this second windingunit 15 is arranged with an opposite rotation direction with respect to that of the first windingunit 14 to intersect with the same, obtaining the stability of the continuous packaging or bundle containing the groups ofbottles 11. - A
second connection module 44, identical to thefirst connection module 44 previously described, allows the connection of the second windingunit 15 with the cuttingunit 16 which separates the continuous packaging or bundle being fed forwards containing groups of bottles into singlefinal packagings 18 containing a group ofbottles 11 and contained in at least two layers of film made of extensibleplastic material 17 wound according to opposite rotation directions. - This cutting
unit 16 must intervene to separate the continuous packaging or bundle moving forwards containing groups of bottles thus formed intofinished packagings 18, as shown in the example, containing sixadjacent bottles 11 in pairs. - In a preferred embodiment, said cutting
unit 16 comprises aframe 50 which supports it. The cuttingunit 16 in the non-limiting example comprises aside cutting device 51 and an upper andlower cutting device 52. The cuttingunit 16, in fact, acts on the plastic material wound in the continuous packaging or bundle around the groups ofbottles 11 to effect a cutting on four winding sections, two vertical and two horizontal, which form the perimeter of the continuous packaging or bundle. - The
frame 50 carries aslide 53, free to move forwards and backwards, bearing theside cutting device 51 and the upper andlower cutting device 52 on relative guides 67. Saidslide 53 moves forwards and backwards beneath aconveyor belt 55 whose upper part is designed for being wound around end pulleys 54 and supports the various pairs ofbottles 11 being packaged or continuous bundle which arrive wound in two layers of film arranged spirally crossed while moving forwards. Theconveyor belt 55 consequently accompanies the various groups of pairs of bottles wound in the single packaging or continuous bundle during the complete cutting step. - The
side cutting device 51 provides a portal 56 containing twovertical side blades 57 movably positioned onhorizontal guides 58 for moving forwards and backwards. In this way, the twovertical side blades 57 can be moved towards and away from the plastic material of the continuous packaging wound around the groups ofbottles 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. Thevertical 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 ofproducts 11 that is moving forwards in the packaging machine. - The two
vertical blades 57 are driven in this movement by adouble crank mechanism 59, 59', upper and lower, actuated by asingle motor 60. - The upper and
lower cutting device 52 also provides a portal 61 containing two upper 62 and lower 62' horizontal blades movably positioned onhorizontal guides 63 for moving forwards and backwards on a vertical plane. In this way, the twohorizontal blades 62, 62' can be moved towards and away from the continuous packaging or bundle containing the groups ofbottles 11 comprising two layers of film wound in an opposite direction around theproducts 11 to effect a cutting on two horizontal sections of said continuous packaging on opposite sides of the continuous packaging or bundle. Also in this case, the twohorizontal 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 adouble crank mechanism 64, 64', upper and lower, actuated by asingle motor 65. - Furthermore, the lower blade 62' in its forward and backward, upward and downward movement moves in an omega-shaped loop formed in the
belt 55, wherein said omega-shaped loop can be moved together with theslide 53 and with the upper andlower cutting device 52. -
Figures 14 and15 respectively show sectional views in correspondence with the upper andlower cutting device 52 of the cuttingunit 16 with the upper 62 and lower 62' horizontal blades andside cutting device 51 with thevertical 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 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 thebottles 11 being packaged and above all in the quantity ofbottles 11 of the single group required in the final packaging to be obtained. For this purpose, adjustable struts/rods 68 connect the twoportals cutting devices -
Figures 16 and17 are a raised side view and a sectional view that show an alternative embodiment of a cutting unit 16' forming part of the packaging machine. - In this embodiment, the same elements are indicated with the same reference numbers.
- Only one cutting device 51' is present, which provides
side cutting blades 57. In this example, theside blades 57 slide until they reach the intermediate part of the twobottles 11, adjacent at the front or back of the group, wound in the extensible film effecting a transversal cut of two opposite halves of said continuous packaging containing the groups ofbottles 11. - As clearly illustrated in the sectional view, in this cutting unit 16' of
figures 16 and17 , theside 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. - The cutting operations can therefore be accelerated with respect to the
other cutting unit 16 previously described. Said cutting unit 16' can provide various devices 51' in order to accelerate the separation operations of the packagings, increasing the productivity. - In this machine of the invention, a new packaging method is also provided. 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 saidadjacent 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 firstring winding unit 14 of extensible film and winding the groups ofproducts 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 secondring 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 cuttingunit 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 ofproducts 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 ring winding machines 32 provided for each of the tworing winding units ring winding machines 32 provided for each of the tworing winding units - The functioning of a packaging machine in extensible film of groups of products according to the invention is as follows.
- As already specified,
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 ofbottles 11 thus arranged are moved forwards up to aconveyor belt 12 for feeding the packaging machine as far as the inlet of theordering unit 13. - A correct and constant reciprocal arrangement of the
bottles 11 of each group is obtained in thisordering unit 13, thanks to the presence of the twobelts 21, 21' withdowels 26 facing and protruding from onebelt 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 tworing winding machines 32 is active. The plastic film of the reel of thisring winding machine 32 is caused to rotate and to be wound around the single group ofbottles 11 moving forward on theconveyor 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 windingunit 14 and, passing onto afurther conveyor belt 29, they reach theconnection module 44 towards the subsequent second windingunit 15. - During the passage inside the first winding
unit 14, the feeding is favoured by the presence of twoconveyor belts connection module 44 to favour the forward movement of the continuous packaging or bundle of groups of pairs ofbottles 11, at the same time keeping them well positioned. - Continuation of the feeding brings said continuous packaging or bundle containing groups of bottles spaced apart, towards the second winding
unit 15 and, for example, above therespective conveyor belt 29, the winding of the first of the tworing winding machines 32 of the second windingunit 15 is actuated at the inlet. Also in this case, the plastic film of the reel of thisring winding machine 32 is caused to rotate and to be wound around the groups ofbottles 11 already wound by the first film moving forward on theconveyor belt 29 and between the pairs of side guiding bars 30. It should be noted, however, that the rotation of thering winding machine 32 in this case is effected in an opposite direction to the rotation of the first windingunit 14 so as to intersect the layers of film of the first winding with the layers of film of this second winding. - 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 twoconveyor belts unit 15 andfurther conveyor belts second connection module 44 positioned before the inlet to the cuttingunit 16. - The continuous bundle then passes onto the
conveyor belt 55 positioned in the cuttingunit 16 which supports and accompanies the continuous packaging or bundle containing the groups ofbottles 11 during the subsequent entire cutting step. - The
slide 53 containing the twoside 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 theslide 53 and bundle containing the groups ofbottles 11 is zero. - During a cutting step, the
vertical side blades 57 of theside 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 andlower cutting device 52 act on a different section of the continuous bundle again at the ends of the groups ofbottles 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 thecutting devices cutting devices 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, in fact, 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, in fact, 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. - The objective mentioned in the preamble of the description has therefore advantageously been achieved.
- 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.
- The forms of the structure for the provision of a machine and method of the present invention, as also the materials and assembly modes, can naturally differ from those shown for purely illustrative and non-limiting purposes in the drawings.
- The protection scope of the present invention is defined by the enclosed claims.
