Definitions

  • the present invention relates to a label application apparatus and method.
  • the present invention relates to an apparatus and a method for applying labels of the type cut off a roll of labelling material at appropriate lengths and then stuck, by means of melted glue, onto the outer surfaces of articles - in particular receptacles, such as bottles, pots, cans or the like - travelling along an article path.
  • labels are attached on the external surfaces of respective articles by means of melted glue previously spread on the back surfaces of the labels themselves.
  • labels are cut from a web at appropriate lengths and then advanced by a transfer drum towards a label application station, at which labels are applied onto the respective articles.
  • a glue applicator such as a rotatable glue roller, cooperating tangentially with the transfer drum, or spray or injector systems; in practice, as it is advanced by the transfer drum, each label receives, on the opposite side thereof with respect to the transfer drum, the melted glue by the glue applicator.
  • Label application apparatuses and, more in general, labelling machines for automatically performing these operations are well known in the art and their use is widespread in the packaging industry.
  • the articles are typically carried by a carrousel along an article path so as to advance towards the label application station.
  • a web of labelling material is fed from a roll-feeding unit to the outer lateral surface of the transfer drum, whereby said web is brought into contact with cutting means to be cut into labels of appropriate length.
  • the labels are retained by respective retaining regions of the outer lateral surface of the transfer drum; these retaining regions are equally spaced angularly around the axis of the transfer drum and are separated from each other by respective transition regions, along which labels fed from the roll-feeding unit slide prior to reaching the respective retaining regions.
  • the outer lateral surface of the transfer drum comprises a plurality of orifices that can be fluidically connected with a suction source.
  • the present invention also relates to a label application method as claimed in claim 10.
  • Number 1 in Figure 1 indicates as a whole a label application apparatus according to the present invention.
  • Apparatus 1 is adapted to be used for handling, transferring and applying labels 2 to respective articles 3 or, more specifically, receptacles, such as bottles, as said articles 3 are advanced along a path P.
  • each article 3 is defined in the example shown by a bottle having a longitudinal axis A, a base 3a and a removable cap 3b, which is applied on an open neck 3c of the bottle itself and defines an end of the latter opposite the base 3a.
  • Apparatus 1 comprises:
  • articles 3 are advanced in vertical positions along path P, i.e. with their axes A vertically oriented and orthogonal to the path P itself; the same applies to the web 5 and the labels 2, which are in turn advanced along the respective paths M, N in vertical positions, i.e. parallel to the axes A of the articles 3, so that the labels 2 themselves can be applied on outer lateral surfaces 3d of the respective articles 3.
  • path M is also parallel to the longitudinal size of the web 5.
  • first conveying means 8 comprise a substantially cylindrical label transfer drum 16 having a vertical central axis X, orthogonal to the plane on which path N lays; transfer drum 16 is configured to retain the labels 2 on its outer lateral surface 18 by suction and to rotate about the axis X to transfer each label 2 from input station 9 to label application station 10 along path N.
  • label path N is tangential to article path P at the label application station 10.
  • label application station 10 is arranged at a given angular distance from the input station 9 about the axis X of rotation of transfer drum 16.
  • Outer lateral surface 18 of transfer drum 16 comprises one or more label retaining regions 20, three in the example shown, provided with a plurality of through holes (not visible) selectively communicating in a known manner with a suction or vacuum source (known per se and not shown) through internal passages (not visible) of the transfer drum 16 itself.
  • these internal passages can be connected to the suction or vacuum source by means of suitable orifices or manifolds present on a non-rotating base (known per se and not shown) on which the transfer drum 16 is supported and rotated.
  • Retaining regions 20 are adapted to retain the respective labels 2 during transfer thereof from input station 9 to label application station 10.
  • each retaining region 20 presents, at its opposite circumferential ends, respective interaction zones 22, 23 designed to engage or interact, in use, with a leading end portion 2a and a trailing end portion 2b of a relative label 2, respectively.
  • the interaction zone 22 defines a front or downstream interaction zone of the relative retaining region 20, whilst the interaction zone 23 defines a back or upstream interaction zone 23 of the retaining region 20 itself with reference to path N, in the sense that the interaction zone 22 comes before the interaction zone 23 by proceeding along the path N itself.
  • these interaction zones 22, 23 are slightly protruding from the outer lateral surface 18.
  • the interaction zones 22, 23 may be also part of a respective continuous arc-shaped retaining region 20, having a centre different and spaced from axis X of transfer drum 16; in this way, transfer drum 16 has an approximately cylindrical, lobed configuration.
  • the interaction zones 22, 23 also present a plurality of through holes (not visible) selectively communicating with the suction or vacuum source.
  • Retaining regions 20 of outer lateral surface 18 are equally spaced angularly around axis X of transfer drum 16 and are separated from each other by respective transition regions 25, on which labels 2 fed from cutting unit 7 slide prior to reaching the respective retaining regions 20.
  • each transition region 25 extends between the back interaction zone 23 of a downstream retaining region 20 and the front interaction zone 22 of an upstream retaining region 20 and is provided with through holes (not visible), also selectively connectable with the suction or vacuum source.
  • transition regions 25 are present on the transfer drum 16, which are equally spaced angularly from one another about the axis X.
  • each retaining region 20 extends from the rear edge of a back interaction zone 23 to the front edge of a relative front interaction zone 22, whilst the corresponding transition region 25 extends from this front interaction zone 22 to the next interaction zone 23.
  • the overall number of transition regions 25 provided in the outer lateral surface 18 of the transfer drum 16 can vary accordingly, depending on the capacity of the apparatus 1 and, even more so, on the length of the labels 2 to be processed, the minimum number being one.
  • each transition region 25 has a smaller angular extension or width around axis X than the angular extension or width of the relative retaining region 20 and, in use, can serve the purpose of starting to attract the relative label 2 at input station 9, so that such label 2 is then received on the retaining region 20 directly upstream and on the relative interaction zones 22, 23.
  • each transition region 25 may also have the same angular extension around axis X as the relative retaining region 20 or even a larger angular extension than that of such retaining region 20, depending on the lengths of the labels 2 to be applied on the articles 3.
  • the transfer drum 16 works conventionally by rotating in the direction indicated by the hatched arrow in Figures 2 , 4 and 5 , so that it first receives, substantially at the input station 9, the web 5 of labelling material, which is then cut to obtain a label 2 of the desired length.
  • conveying means 11 comprise a carrousel 27 rotating about an axis Y, parallel to axis X, to transfer the articles 3 along path P.
  • carousel 27 receives a sequence of articles 3 to be labelled by an inlet star wheel 28, which cooperates with carousel 27 at input station 12 and is mounted to rotate about a longitudinal axis T parallel to axes X, Y.
  • Carousel 27 releases a sequence of labelled articles 3 to an outlet star wheel 29, which cooperates with carousel 27 at output station 13 and is mounted to rotate about a longitudinal axis Z parallel to axes X, Y, T.
  • Carrousel 27 comprises a plurality of support plates 30, which are equally spaced about rotation axis Y, are mounted along a peripheral edge 31 of the carrousel 27 itself and are moved by the latter along an annular path.
  • the article path P is defined by an arc-shaped portion of the annular path of the plates 30; as a matter of fact, path P starts from input station 12 and ends at output station 13, both stations being arranged along the annular path of the plates 30.
  • Each support plate 30 is rotatable about a respective axis W, parallel to the axis Y of the carrousel 27.
  • each support plate 30 is configured to support the relative article 3 in a vertical position with its axis A coaxial to the axis W of the support plate 30 itself; in this way, rotation of each support plate 30 about its axis W produces a corresponding rotation of the supported article 3 about the relative axis A.
  • Rotation of each support plate 30 is activated at label application station 10 by control unit 14 so as to rotate the relative article 3 about its axis A and to produce wrapping of the relative label 2, fed by transfer drum 16, on the outer lateral surface 3d of the article 3 itself up to take a tubular form.
  • glue applicator 15 is advantageously arranged adjacent to carousel 27 and between input station 12 and label application station 10 with reference to path P and is configured to spread in use a given pattern ( Figures 1 , 3 , 5 , 6, 8 and 9 ) of melted glue on a given area of each article 3 advancing along the path P itself.
  • glue applicator 15 comprises glue feeding means 32 configured to apply at least one strip G of glue on the outer lateral surface 3d of each article 3, parallel to the longitudinal axis A of the article 3 itself and to the axes X, Y, T, Z and W.
  • glue feeding means 32 preferably comprise a glue roller 33 having an axis R parallel to axes X, Y, T, Z and W and cooperating tangentially with the outer lateral surface 3d of each article 3.
  • glue roller 33 is mounted to rotate about its axis R and has an outer lateral surface covered by melted glue and cooperating tangentially with the articles 3 advanced along path P.
  • each article 3 contacts, on its outer lateral surface 3d, the glue roller 33 to be spread with the strip G of melted glue.
  • a predetermined glue strip G is applied by the glue roller 33 onto the area of the outer lateral surface 3d of each article 3 where wrapping of the relative label 2 starts and ends ( Figures 3 , 5 and 8 ).
  • labels 2 are progressively separated from web 5 of labelling material by cutting unit 7 and then fed, one after the other, to transfer drum 16.
  • labels 2 are rotated by the transfer drum 16 along path N from input station 9 to label application station 10.
  • the labelling material forming each label 2 slides along a relative transition region 25 prior to reaching the subsequent retaining region 20.
  • each label 2 is supported by transfer drum 16 along the side destined to define the front surface when the label 2 itself is applied onto the respective article 3.
  • articles 3 are fed, one after the other, to respective support plates 30 of carousel 27 by input star wheel 28 at input station 12 and are advanced along path P by the carrousel 27 itself towards label application station 10.
  • each article 3 interacts with glue roller 33 for retaining from the latter a strip G of melted glue on the area of its outer lateral surface 3d destined to receive the leading and trailing end portions 2a, 2b of a relative label 2.
  • Glue roller 33 also rotates about its axis R in a direction opposite the one of carousel 27 about axis Y.
  • the strip G of melted glue spread by glue roller 33 on the outer lateral surface 3d of each article 3 has the same height as the respective label 2 to be applied on such article 3.
  • the leading end portion 2a of one label 2 adheres to a longitudinal region G1 of strip G of glue provided on the respective article 3, namely the one defining the upstream end region of such strip G with reference to the direction of rotation of the article 3 itself about its axis A (counterclockwise direction in Figure 2 ).
  • longitudinal regions G1 and G2 of the strip G of glue are placed laterally adjacent to one another.
  • leading end portion 2a and trailing end portion 2b of each label 2 cooperate head-to-head with one another.
  • the articles 3 After application of the labels 2, the articles 3 are advanced by carousel 27 towards the output station 13, where they are released to the output star wheel 29.
  • Number 1' in Figure 11 indicates as a whole a different embodiment of a label application apparatus according to the present invention; apparatuses 1 and 1' being similar to one another, the following description is limited to the difference between them, and using the same references, where possible, for identical or corresponding parts.
  • apparatus 1' differs from apparatus 1 in that glue feeding means 32 of glue applicator 15 comprise a spraying or an injecting unit 34 adapted to spread a strip G of melted glue on the outer lateral surface 3d of each article 3.
  • glue feeding means 32 of glue applicator 15 comprise a spraying or an injecting unit 34 adapted to spread a strip G of melted glue on the outer lateral surface 3d of each article 3.
  • apparatus 1' The operation of apparatus 1' is completely analogous to that of apparatus 1 and is not repeated for the sake of conciseness.
  • Number 1 in Figure 12 indicates as a whole a further different embodiment of a label application apparatus according to the present invention; apparatuses 1" and 1' being similar to one another, the following description is limited to the difference between them, and using the same references, where possible, for identical or corresponding parts.
  • apparatus 1" differs from apparatus 1' by comprising a further glue applicator 35 arranged adjacent to transfer drum 16 and between input station 9 and label application station 10 with reference to path N; control unit 14 is configured to selectively activate glue applicator 35 each time that back interaction zone 23 passes by the glue applicator 35 itself so as to apply a given pattern of melted glue, a further strip H, on the trailing end portion 2b of the relative label 2 engaging such back interaction zone 23 and to allow, during wrapping of each label 2 on the respective article 3, that the trailing end portion 2b overlaps the leading end portion 2a of the same label 2 and adheres thereto ( Figure 13 ).
  • glue applicator 35 preferably comprises a spraying or an injecting unit 36 similar to spraying or injecting unit 34 and adapted to spread a strip H of melted glue on the trailing end portion 2b of each label 2; strip H is parallel to strip G; in addition, strip G is preferably wider that strip H.
  • glue applicator 35 may also comprise a glue roller, similar to glue roller 33 and having, on its outer lateral surface, at least one projecting rib covered with melted glue and driven by control unit 14 to contact each label 2 advanced by transfer drum 16 at each back interaction zone 23 - which in this case may be defined by a back pad with a damping action - in order to apply the glue only on the trailing end portion 2b of each label 2.
  • apparatus 1" differs from the ones of apparatuses 1, 1' only in that the trailing end portion 2b of each label 2 receives a strip H of melted glue while the label 2 itself advances along path N from input station 9 to label application station 10.
  • a further layer of glue represented by the strip H, is interposed between the overlapped leading and trailing end portions 2a, 2b of each label 2.
  • the construction of the transfer drum 16 is easier than in the prior art, as such transfer drum 16 does not need to be provided with damping pads to allow the leading and trailing end portions 2a, 2b of each label 2 to cooperate with glue roller 33.
  • the possible contamination of the transfer drum 16 is limited with respect to the prior art solutions, as the melted glue is only applied on the trailing end portion 2b of each label 2 and not to the opposite end portions thereof.
  • the strip G may even be larger than expected - as the labels 2 are then often destined to cover the articles areas of application of the glue.
