Description
Technical Field
The utility model relates to a label sticking machine and a label sticking machine of corresponding work for the all-round hot glue label sticking of empty bottle made by plastics.
Background
It is known that, for hot-glue labeling of containers, sheet-shaped labels are first separated from a label web continuously supplied from a reel in a cutting machine, and are sucked up on a continuously rotating vacuum transport drum for subsequent transfer of the labels onto the containers, and are therefore guided towards a glue roller during the cycle and are thereby coated with hot glue. In this case, the glue is usually applied only to the beginning and end regions of the labels in such a way that the labels are sucked by the vertically oriented suction bars and are selectively brought into contact with the glue rollers. For this purpose, the suction strips project radially on the vacuum transport cylinder.
Alternatively, the labels, which are respectively pre-glued on the outside, can be continuously supplied from a roll, separated and transferred onto a vacuum transport cylinder, as is known, for example, from EP 2711303 a 1.
It is then known to place the label on the container running alongside by first guiding the start area of the label, which has been glued, towards the container, winding the label onto the container by rotating the container around itself and finally fastening by the finish-gluing section. In principle, it has been found that the end coating is formed, for example, with a width of at least 20mm, so that the end coating is located partly in the lower label position on the container and partly directly on the outer wall of the container. A corresponding method is described, for example, in DE 102015214011 a 1.
Alternatively, the label can be first attached to the container with the concave side wall profile by means of the start glue application, then wound and bonded with overlap in order to finally fasten the label tightly by shrinking. The starting glue can then, for example, be applied only to suitable outwardly projecting wall sections in the form of adhesive dots. This process is described, for example, in EP 1634817 a 2.
However, after hot-glue labeling of relatively large empty bottles, significant crease formation, doming or similar undesirable deformation or damage of the label on the finished filled bottle is often observed upon subsequent product filling. This undesired effect has not been clarified to date, with the increase in the bottle cross-section during filling which may occur depending on the product weight and the wall thickness of the empty bottle.
There is therefore a further need for an improved method and machine for labeling empty bottles made of plastic, in particular hot-glue labeling, which is improved in this respect, in particular during subsequent product filling.
SUMMERY OF THE UTILITY MODEL
The proposed task is solved by a labeling machine for the circumferential heat labeling of empty bottles made of plastic as follows. The labeling machine comprises a revolving and self-rotating holder for the empty bottles and a vacuum transport drum on which suction strips are formed for producing the adhesive strips on the labels and for placing the labels on the empty bottles, so that the adhesive strips for the initial end fastening do not extend over the entire label height, but rather leave a sliding region on and/or under them towards the empty bottles, and the adhesive strips for the final end fastening at the empty bottles are arranged between overlapping layers of the labels without contacting the empty bottles.
In accordance with the invention, a method is provided for labeling empty bottles made of plastic, in particular made of PET, and in particular for labeling hot glue, wherein a label having a first adhesive strip for the beginning end fastening and a second adhesive strip for the ending end fastening is provided, in particular by producing the adhesive strips on the label by selective hot glue application. Alternatively, a label having a first strip of glue for the starting end fastening portion and a second strip of glue for the ending end fastening portion may be separated from a label tape which is selectively pre-glued with a strip of glue.
Further, the label itself is lapped and wound around the empty bottle from the starting end fastening portion.
According to the utility model discloses, a first adhesive tape for beginning end fastening portion does not extend on whole label height. Instead, a sliding area is freed above and/or below it on the label towards the empty bottle. Furthermore, the second strip of glue for ending the end fastening portion at the empty bottle is arranged between the mutually overlapping layers of the label without coming into contact with the empty bottle.
This makes it possible to achieve a longitudinal movement of the empty bottle with the label wrapped thereon and relative to the label in the region of the start fixing portion and in the region of the end fastening portion.
The utility model discloses based on following unexpected recognition, namely, the empty bottle is followed longitudinal direction and is extended according to the stability and the product weight of empty bottle when the product is filled. As a result, the label, which was originally placed correctly on the empty bottle, is severely distorted in such a way that the label exhibits a pronounced fold formation and/or bulging or similar incorrect placement on the finished filled bottle.
After application of the method according to the invention, only the area of the label directly bonded to the bottle wall by means of the first strip of glue needs to follow the longitudinal expansion of the bottle wall caused during filling of the product. In contrast, the label can slide on the bottle wall in the coupled sliding region of the starting end fastening and in the entire region of the ending end fastening. Thereby, undesired wrinkle formation, bulging or similar erroneous deformations of the label upon product filling can be prevented.
Preferably, the first strip of glue used for the initial end fastening covers at most half, and in particular at most one third, of the height of the label. The remaining part of the label height can then function as a sliding area for the starting end fastening portion. This enables a reliable initial end fastening to be achieved in a particularly efficient manner and at the same time avoids the above-described deformation/damage of the label.
Preferably, the second strip of glue for the end fastening covers at most 5% of the length of the label. In this way, a sufficiently stable end fastening in the overlapping region of the label can be achieved without the adjacent bottle wall directly participating in the adhesive connection of the end fastening. Thus, a relatively good sliding property of the label on the bottle wall in the region of the end fastening portion is obtained.
Preferably, the width of the second strip of glue for the end fastening portion matches the label length and the circumference of the empty bottle, so that the second strip of glue for the end fastening portion is present substantially only between the overlapping layers of the label. This prevents the hot glue from coming into contact with the bottle wall and escaping past the overlapping layers of the label into the label region visible from the outside.
Preferably, the label is placed onto the empty bottle before the directly coupled product is filled, in particular within the machine section. Thus, product filling can be performed particularly efficiently without undesired deformation of the placed label.
Preferably, the first strip of glue for the initial end fastening is dimensioned and arranged such that the empty bottles can perform thereon and thereunder a relative movement in the longitudinal direction with respect to the label caused in the filling of the product. This relative movement can also be understood as an increase in the nominal length of the entire labeled wall area or of the wall area covered only by the sliding area.
The first strip of glue can be optimized, for example on the basis of empirical knowledge, so as to obtain a reliable fastening and even abutment of the label before and after subsequent filling of the product. For example, the first strip of glue can be arranged such that the expansion can take place both upwards and downwards relative to the label.
Preferably, a larger sliding area is left open in the upper half of the label than in the lower half of the label from the starting end fastening portion. In this way, it is possible to take into account the length expansion caused by the weight of the product to be filled in a targeted manner, and therefore to take into account that the wall regions which are more strongly loaded in the upper half of the label expand more strongly than the wall regions which are less strongly loaded in the lower half of the label.
Preferably, the labels are selectively guided in the region of the first and second strip of glue towards the glue roller by means of respectively associated suction strips. The suction strip then has a press surface shaped in accordance with the first strip for the beginning of the end fastening and the second strip for the end fastening, which press surface selectively brings the label into contact with the rubber roller in relation to the adjoining region of the suction strip and/or of the vacuum feed cylinder.
Alternatively, the label is provided in the area of the strip of glue, optionally in a pre-glued manner. Pre-gumming means here that the label is provided in the form of a label tape that is externally gummed before it is used in the labelling unit. The label tape, optionally pre-glued with a strip of glue, can be unwound from a reel and separated into labels in a labelling unit in a manner known in principle. The term glue thus includes all suitable adhesives, such as hot melt adhesives or adhesives containing solvents.
Preferably, the label is secured to the empty bottle without shrinkage. This facilitates the sliding of the label in the longitudinal direction of the empty bottle during subsequent product filling.
Preferably, the empty bottles, in particular made of PET, have a filling volume of at least 1 liter. In the case of such empty bottles, particularly significant length expansion occurs as a result of the product weight upon filling of the product. The method can therefore be used particularly advantageously in such empty bottles.
Preferably, the method further comprises a step for filling the product into the previously labeled empty bottles, in particular by means of a propellant gas, wherein the empty bottles are moved/expanded in the longitudinal direction relative to the abutting sliding region. By the product filling with the addition of propellant gas, additional pressure is built up in the empty bottle, so that the empty bottle may expand strongly in the longitudinal direction. Generally, the label will also expand in the transverse direction, causing the cross-section of the label to increase.
The proposed task is also solved according to the following labeling machine. The labeling machine is used for labeling empty bottles all around and in particular for hot-glue labeling of empty bottles made of plastic, and comprises a revolving and self-rotatable holder for the empty bottles and a vacuum transport drum on which a suction strip is formed, in particular, for producing a glue strip on the label. The vacuum transport cylinder is configured for applying the label to the empty bottle according to the method described above.
Preferably, the suction strip assigned to the first adhesive strip for the initial end fastening has a pressing surface which interacts with the rubber roller, the total height of which is at most half, and in particular at most one third, of the label height nominally assigned to the transport cylinder. This enables a sufficiently stable starting end fastening and at the same time a sufficient movability of the label in the longitudinal direction with respect to the empty bottle upon subsequent product filling.
Preferably, the pressing surface is arranged/distributed with a highly asymmetrical bias towards the lower half of the label with respect to the label.
Preferably, the suction strip assigned to the second strip of glue for the end-end fastening of the label has a pressing surface that cooperates with the glue roller, the width of which is at most 5% of the length of the label nominally assigned to the transport cylinder. In this way, a sufficiently stable finish end fastening portion can be produced while achieving good sliding properties of the label on the empty bottle in the overlap region of the label.
The object is also achieved according to a machine section which is designed for filling products into labeled empty bottles made of plastic and which, in addition to a labeling machine according to at least one of the preceding embodiments, also comprises a filling machine arranged downstream of the labeling machine.
Drawings
The preferred embodiment of the invention is illustrated. Wherein:
fig. 1 shows a side view of an empty bottle and an associated label;
FIG. 2 shows a cross-section through an empty bottle and label;
FIG. 3 shows the label tensioned between the suction strips; and
fig. 4 shows a schematic top view of a labeling machine for labeling the hot glue of empty bottles and a subsequent product filling device.
Detailed Description
Fig. 1 shows, in a side view, an exemplary empty bottle 1 made of plastic, in particular PET, with a label 2 (full-circumference label) placed thereon all around. In the hatched area a first strip of glue 3 for the initial end fastening of the label 2 on the empty bottle 1 and a second strip of glue 4 for the end fastening of the label 2 wound onto the empty bottle 1 on itself are indicated.
The second strip of glue 4 preferably extends over the entire label height 5. Whereas the first strip of glue 3 does not cover the entire label height 5 but is bordered thereon and therebelow, i.e. in the longitudinal direction 1a of the empty bottles 1, by an upper sliding area 6 and a lower sliding area 7.
The sliding areas 6, 7 enable (schematically indicated by means of double arrows) a relative movement 8, 9 of the label 2 in the longitudinal direction 1a on the empty bottle 1 during the longitudinal expansion of the empty bottle 1 when/after a subsequent filling of a liquid product, such as a beverage, into the empty bottle 1. Longitudinal expansion is caused by the weight of the product being inflated and may be enhanced by the propellant gas contained within the product.
Fig. 2 shows an empty bottle 1 in cross section along section line a-a, with its circumference 1b and a matching label 2 adapted thereto. Hereby, a first strip of glue 3 for fastening the beginning end fastening portion of the label 2 on the empty bottle 1 and a second strip of glue 4 for ending the end fastening portion are arranged substantially overlapping. This is particularly well visible in the enlarged section Z.
Only the glue strip 3 for the initial end fastening directly contacts the empty bottle 1. Whereas a second strip of glue 4 for finishing the end fastening is arranged between the two mutually overlapping layers 2a, 2b of the label 2 in such a way that the second strip of glue 4 does not come into direct contact with the empty bottle 1. For this purpose, a label region 2c, which is usually contained in the end fastening according to the prior art, is left free, for example, from the second strip of glue 4 and the end fastening, in which the lower layer 2a is not present.
It is thereby avoided that the second strip of glue 4 is immovably attached to the empty bottle 1, which would otherwise hinder the relative movement of the label 2 with respect to the empty bottle 1 in its longitudinal direction.
Fig. 3 shows a label 2 (full-circumference label) tensioned between a first suction strip 10 and a second suction strip 11 (of a vacuum transport cylinder), which has a back side directed out of the drawing plane, which back side is provided with a first and a second strip of glue 3, 4. For this purpose, at least one pressing surface 10a corresponding to the shape of the first adhesive strip 3 is formed on the first suction strip 10, and at least one pressing surface 11a corresponding to the second adhesive strip 4 is formed on the second suction strip 11.
The labels 2 are sucked in a manner known in principle in the region of the pressing surfaces 10a, 11a and are guided to the associated glue roller. The suction strips 10, 11 furthermore comprise fixing surfaces 10b, 11b for the labels 2 set back with respect to the pressing surfaces 10a, 11 a. The labels 2 are sucked in a controlled manner in a manner known in principle onto the press surfaces 10a, 11a and the fixing surfaces 10b, 11b by means of the suction openings 10c, 11c, respectively, and are brought into contact with the rubber roller only with the press surfaces 10a, 11a projecting radially on the vacuum feed cylinder in order to selectively produce the rubber strips 3, 4 in the region of the press surfaces 10a, 11 a.
In a manner known in principle, the labels 2 are produced by separation from a strip of labels continuously supplied from a roll.
In fig. 3, the label height 5 and the label length 12 are shown in comparison with the dimensions of the pressure surfaces 10a, 11a of the suction strips 10, 11 and thus in comparison with the dimensions of the first and second strips of glue 3, 4 of the respective defined format. The pressing face 10a of the first suction bar thus has a height 13 (defined transversely to the transport direction) and the pressing face 11a of the second suction bar 11 has a length 14 (defined in the transport direction).
The pressing surface 10a produces a first strip of glue 3 with a corresponding height 13. The first strip of glue 3 therefore does not extend over the entire label height 5. More precisely, the unglued sliding regions 6, 7 are held spaced apart from the rubber roller by means of the fixing surfaces 10b which are connected to the pressing surface 10a above and below, and are thus free from the starting end fastening. Correspondingly, an immovable initial end fastening of the label 2 on the empty bottle 1 is effected only in the area of the first strip of glue 3, while the adjacent sliding areas 6, 7 enable a relative movement 8, 9 of the empty bottle 1 with respect to the label 2 in the longitudinal direction 1 a.
In fig. 3, the height 13 of the pressing surface 10a, and thus the height of the first strip of glue 3 produced in this way, is also indicated schematically, at most half, and in particular at most one third, of the label height 5.
Furthermore, the first strip of glue 3 is preferably not arranged centrally with respect to the label height 5, but is offset downwards with respect to the (imaginary) horizontal centre line 15. The upper sliding area 6 is therefore larger, i.e. more vertically extensive, than the lower sliding area 7. As a result, the wall section of the empty bottle 1 on the upper sliding region 6, which is clearly set by the product weight and therefore clearly expands during filling, can be moved further relative to the label 2 than the wall section on the lower sliding region 7, which is less set and less expanded.
The pressing surface 11a produces a second strip 4 of corresponding length 14. In fig. 3, the pressing surface 11a is schematically and exemplarily shown, in turn, as a second strip of glue 4 having a length 14 that covers at most 5%, preferably between 2% and 5%, of the label length 12. Thus, the second strip of glue 4 for the end fastening portion of the label 2 can be efficiently arranged in the area between the layers 2a, 2b of the label 2 shown in fig. 3, without being in direct contact with the empty bottle 1.
The first strip of glue 3 and the second strip of glue 4 are then preferably arranged on top of each other on the empty bottle 1 that has been labelled.
As can be seen from fig. 4, the labeling machine 21 for hot-glue labeling of empty bottles 1, respectively made of plastic, preferably comprises a holder 23 for continuously transporting the empty bottles 1 and for rotating the empty bottles 1 about themselves, revolving on a container turret 22. The suction strips 10, 11 are arranged in pairs on a vacuum transport cylinder 24 and interact in a manner known in principle with a rubber roller 25 for transporting hot glue. The vacuum transport cylinder 24 and the rubber roller 25 are part of a labeling unit 26, which comprises further units for providing labels 2, which are known in principle and therefore not labeled in detail in fig. 4.
Fig. 4 furthermore schematically illustrates that the labeling machine 21 is preferably a component of a machine section 27 having a filling machine 28 arranged downstream of the labeling machine 21. Thus, as described previously, the empty bottles 1 that have been labeled may expand in the longitudinal direction 1a relative to the labels 2 as they are filled with product in the filling machine 28.
Here, a relatively large increase in length occurs in the upper region of the empty bottle 1 on the basis of the weight force exerted by the filled product, whereas a relatively small increase in length occurs in the region of the empty bottle 1 near the bottom. This is schematically indicated in fig. 1 by the different long double arrows for the respective relative movements 8, 9 between the empty bottle 1 and the label 2.
Accordingly, the first strip of glue 3 for the initial end fastening is preferably not produced vertically centered on the label 2, but is offset relatively downwards. The sliding area 6 above the first strip of glue 3 thus extends over a larger vertical partial area of the label 2 than the sliding area 7 below it. Depending on the size and shape of the empty bottle 1, the height position of the first strip of glue 3 relative to the vertical center line 15 of the label 2 can be specifically adapted by a corresponding arrangement of the pressure surface 10a on the first suction strip 10.
The method can thus be performed as follows:
the labels 2 are continuously supplied from a roll in the form of a label tape and are separated off by a cutting machine and transferred to a vacuum transport cylinder 24 in a manner known in principle.
The labels 2 are suctioned substantially in their entirety onto the vacuum transport cylinder 24, wherein the regions of the labels for the beginning and end fastening are received by the suction strips 10, 11.
Only the label regions provided for the first and second adhesive strips 3, 4 are then selectively brought into contact with the adhesive roller 25 by means of the pressure surfaces 10a, 11a formed on the suction strips 10, 11 and are thus selectively coated with hot glue.
With the vacuum transport cylinder 24 continuing to rotate, the labels 2 are transported into the region of the container turret 22 and are guided by means of the suction strips 10, 11 towards the empty bottles 1 to be labeled.
The initial end fastening is effected by means of the first suction strip 10 by means of the first glue strip 3. From there on, the subsequent area of the label 2 is wound onto the empty bottle 1 by a suitable rotation about itself. The second suction bar 11 finally guides the second strip of glue 4 for realizing an overlapping end-fastening for the almost completely wound label 2, so that the second strip of glue 4 does not directly contact the empty bottle 1 below it.
The lower layer 2a and the upper layer 2b of the label 2 are joined together in an overlapping manner by the second strip of glue 4 lying in the middle in order to achieve the end-fastening without producing an adhesive connection with the empty bottle 1 lying thereunder in the region of the end-fastening.
Thus, a relative movement 8, 9 of the label 2 in the longitudinal direction 1a relative to the empty bottle 1, which substantially corresponds to the starting end fastening portion, can be achieved in the entire area of the ending end fastening portion.
The relative movement 8, 9 in the longitudinal direction 1a is limited only by the first strip 3 at the initial end fastening. The first strip of glue 3 is dimensioned and, if necessary, also product-dependent, for example product-dependent on the carbonation, and is arranged on the label 2 such that the adjacent sliding regions 6, 7 are used to achieve a defined label placement even after filling.
In particular, undesired formation of wrinkles, bulging or similar deformations of label 2 when subsequently filling the product into the empty bottle 1 can be avoided. At the same time, the defined length of the empty bottle 1 above and below the first strip of glue 3 and on the layer 2a of the label 2 separating the second strip of glue 4 from the bottle wall is allowed to grow when filling with product.
The label 2 is only wound onto the empty bottle 1 for a low-friction relative movement 8, 9, but not contracted.
Independently of the described length expansion of the empty bottle 1, it can also be expanded transversely thereto, i.e. after filling with product, with a larger cross section than before filling. Such transverse expansion is on the one hand less critical in terms of wrinkle formation etc. of the label 2; on the other hand, the described relative movements 8, 9 in the longitudinal direction 1a are thus only insignificantly impeded.
The fundamental problem of undesired deformations such as creases or even damage to the label 2 occurs in particular in relatively thin-walled plastic containers which in turn have a filling volume of at least 1 litre. In this case, the weight of the product filled causes the length of the empty bottle 1, which in principle jeopardizes the correct placement of the label 2, to expand. In particular, this relates to the region in the upper bottle half. Additionally, this problem may be exacerbated by filling under the influence of the propellant gas.
However, with the described method and the labeling machine 21 working accordingly, an undesired crease formation or similar deformation of the label 2 can be reliably prevented despite such a length extension of the empty bottle 1.
Alternatively, the label 2 may be provided in the form of a label tape (not shown) that is selectively glued with strips of glue 3, 4. In this case, the suction strips 10, 11 on the gluing machine 25 and on the vacuum transport cylinder 24 are optional. As an alternative, one or more serially connected vacuum transport cylinders with perforated circumferential sides can be used for transferring the separated labels, as is known, for example, from EP 2711303 a 1. In order to separate out the labels 2 with the selectively pre-glued glue strips 3, 4, a suitably prefabricated label strip is provided.
