Technical Field of the Invention
[0001] The present invention relates to a device and method for attaching labels, such as
banderoles, label strips, on top of the closure systems for beverage bottles, wherein
the labels are folded and bended in the absence of a conventional piston mechanism
exerting pressure on conveyed bottles.
Background of the Invention
[0002] In beverage bottling plants, closing machines attach closure systems to bottles upon
filling in a continuously conveyed line. Closed bottles are then usually conveyed
to an information adding station, wherein information or banderols, is fixed to the
bottle or its closure. The bottles are then sorted and packaged for shipment out of
the plant.
[0003] Information adding station, mentioned above, generally has a folding and rolling
unit in order to fix labels on the bottles. A conventional pneumatic folding unit
comprises air cylinders, air pipes, elbows, filter, lubricating unit, plastering parts,
aluminum block and control valves. For a mass beverage producer, the speed of the
line is up to 25000 bottles/hour especially for small volumes and for such a fast
line pneumatic components lifetime is dramatically shortened. Inappropriate environmental
conditions and problems at pressurized air line of the producer (bad filtering and
moisture) are also inadvertently affecting a healthy working process. Besides these
complications, conventional pneumatic labeling systems fail to properly fold the sides
of labels or banderoles and further, alignment of labels on the bottles may be poor.
[0004] In some beverage bottling plants, the information adding station applies banderoles
on the tops of the closure systems of beverage bottles. The term "banderoles" as used
in this application also means, depending on the purposes, label strips and/or tax
labels or tax strips or ID strips. Conventional labeling tools mostly apply pressure
on the banderol and hence the closure system of the bottle. A small movement of the
bottle causes the banderol being badly aligned on the closure of the bottle. The piston
mechanism, due to pneumatic constraints, is usually not quick enough to suffice the
needs of the filling line and is therefore a major constraint in the overall process
of beverage production plant.
[0005] Conventional piston mechanisms for labeling are well known, and there are several
patents documents in the corresponding field. One of these is US patent
US4976803A where a pressing station for metal foil sheets applied around the top and the neck
of bottles is disclosed. By means of bell-shaped pressing elements which can axially
be lowered towards the bottle top, the foil sheets are firmly applied to the top of
the closure system and neck of the bottle. Each component of above mentioned systems
needs frequent maintenance and replacement of various pneumatic parts, eventually
increasing service costs. Besides, extend and retract positioning of pneumatic elements
usually need very sensitive adjustments, whereas the pressure deviations in the supplied
air is requiring to re-adjustment of these positioning parameters and supplied pressurized
air also has an additional cost for plant operator.
[0006] The present invention discloses a novel labeling tool which is capable of folding
the sides of labels in the absence of a conventional piston mechanism exerting pressure
on conveyed bottles, therefore preventing shaking or rotating bottle as most of the
piston mechanisms required. The labels fit on the closure systems of the bottles with
a straight alignment. The present eliminated the need for frequent maintenance as
the labeling mechanism is free of parts requiring lubrication or pressurized air supply.
A further advantage achieved by the present invention is the positive impact on the
bottle alignments on a moving conveyor.
Objects of the Invention
[0007] Primary object of the present invention is to eliminate the drawbacks of the conventional
labeling systems identified in the background of the invention.
[0008] A further object of the present invention is to reduce the service and maintenance
costs of a labeling system while providing perfectly aligned and fixed labels.
[0009] Another object of the present invention is to fold the sides of the labels in the
absence of a conventional piston mechanism exerting pressure.
[0010] Another object of the present invention is to create a simplified, non-complex and
economic labeling system for attaching labels on the closure systems of beverage bottles,
whereby the labeling system is adjustable with respect to the size of the bottles.
[0011] Yet another object of the present invention is to increase the speed of labeling
system by elimination of pneumatic parts.
Summary of the Invention
[0012] A labeling tool for folding and attaching labels onto closure systems of beverage
bottles is disclosed. The labeling tool comprised at least two folding means and a
channel formed by and in between said folding means. Both ends of labels are folded
and attached partly on the top and side surfaces of the closure systems of bottles
while, in operation, said bottles move on a conveyor line to which said labeling tool
is installed. The folding means are spaced apart from each other for forming a channel.
In particular, the folding means have inclined inner surfaces which make said channel
a converging channel in the direction of the movement of said conveyor line. The channel
formed by the folding means is converging in at least one direction perpendicular
to the direction of movement of said conveyor line.

[0015] Referring now to the figures outlined above, the present invention proposes a device
and method for attaching labels (14) on top of closure systems of beverage bottles
(15) in a faster and easier way compared to conventional pneumatic systems.
[0016] Fig. 4 demonstrates the folding process of the labels (14) by the usage of a labeling
tool (17) according to the present invention. As shown in Figs 1 and 2, two independents
folding means (13,13a) are adjusted according to diameter of the beverage caps (22)
and a channel (18) is formed by said folding means (13,13a) which are spaced apart
from each other (13,13a). The two ends of said labels (14) are folded onto bottle
caps (22) while moving through said channel (18) on a conveyor line. Said channel
(18) is converging in at least one direction which is perpendicular to the direction
of movement on said conveyor line. As shown in Figures 4 to 8, labels (15) are folded
while being conveyed through said adjusted channel (18) and then bottles are conveyed
to roller units (16) for better attachment of the labels on their closures.
[0017] In order to achieve the objects of the invention, the labeling tool (17) basically
comprises two folding means (13,13a) which have inclined inner surfaces with respect
to the horizontal axis (X, Fig.6) of said labeling tool (17), a channel (18) formed
by and in between said folding means (13,13a), wherein both ends of labels (14) are
folded and attached partly on the top and the side surfaces of the closure systems
(22) of bottles while being moved on a conveyor to which said labeling tool (17) is
installed. The labeling tool (17) further comprises a horizontal plate (23) positioned
on top of the said folding means (13,13a), at least two connection plates (20) enabling
the mounting of the said system located on the horizontal plates (23) by moving along
the vertical "Y" and horizontal "X" directions as shown in Fig.6. The labeling tool
(17) further comprises an auxiliary folding member (19) positioned on one of said
folding means (13,13a) at a lower portion of the same, such that one end of the labels
can be made to adhere a lower portion of the bottle, whereas the other end of the
labels adheres to an upper position of the bottles.
[0018] The labeling tool (17) a minimum level of maintenance since it lacks a large number
of pneumatic components. As a consequence, the labeling tool (17) according to the
present invention enables more efficient labeling, particularly in the desired speed
of labeling as required by the beverage filling plant. As a further consequence, the
labeling tool (17) is extremely cost effective both in terms of its initial cost and
also operational costs during service life.
[0019] According to a preferred embodiment of the present invention, the folding means (13,13a)
being spaced apart from each other (13,13a) for forming a channel (18) are positioned
or adjusted according to the dimension of the bottle closure systems. Even though
a channel (18) is formed naturally by the folding means being in spaced apart position,
said channel is made convergent with the inclined inner surfaces of the folding means
(13,13a) as seen in Figs. 2 and 3.
[0020] An auxiliary folding member (19) is positioned to one of said folding means (13,13a)
at its lower portion. The auxiliary folding member (19) enables folding one end of
the labels (14) such that the labels may adhere to the closures with an uneven distribution.
This is made particularly when a label is deemed to adhere not only to the closure
system but also to the bottle neck in order to provide anti tamper indication. In
such cases the label is folded onto the closure system with an uneven distribution
such that one side of the label is longer than the other side, hence allowing adhesion
to the bottle at the one part. If the lower sleeve of the closure system is somehow
opened for the first time, the label would then tear and tampering would be indicated.
[0021] As shown in figures 4 to 8, labels (14) are fixed on top of the bottle closure systems
(22) of bottles (15) that are moving at a certain speed on top of a conveyor (not
shown). Before entering the labeling unit (17), the labels (14) are partly fixed or
adhered on the top surfaces of closures (caps) of the bottles with the aid of a label
applicator (not shown). The label applicator delivers a label on the top surface of
the cap of each bottle carried on the conveyor. Hence, each bottle arrives the labeling
unit (17) with a partly fixed label as adhered to the upper surface of the cap. Full
adhesion is then achieved by folding the ends of the labels on both sides of the bottle
after which the rolling unit compresses the labels on the side surfaces of the caps
and the bottle neck.
[0022] As shown in fig. 1 to 2, formed channel structure (18) can be adjusted to any of
desired bottle cap (22) diameter. Fig. 6 demonstrates the bottles (15) that are moving
at a certain distance from each other and at a certain speed towards the X axis, as
shown in the Fig. 6. The bottles move along the channel (18) formed by the parts of
the tool (15), the width of said channel being adjustable based on the diameter of
the bottle caps (22). The folding means (13,13a) have increasingly inclined inner
surfaces which enable that labels (14) eventually are folded and attached to the side
surfaces of the bottle cap (22) and the bottle neck.
[0023] The labeling tool (17) as proposed by the present invention is positioned fixedly
during the labeling process by the connection plate (20). The labeling tool (17) comprises
a plurality of connection holes (21) formed on the connection plates (20). Said connection
holes (21) serve to keep the labeling tool (17) stable and integral by use of plurality
of corresponding fixing elements (not shown).
[0024] A horizontal plate (23) is positioned horizontally above one of each said folding
means (13,13a) upper surface with respect to the horizontal axis of said labeling
tool (16). The folding means (13, 13) having inclined inner surfaces are connected
to horizontal plates via a plurality of screws. Labels are first placed on top of
the upper surfaces of bottle caps and then bottles are conveyed through the adjusted
channel (18) formed by folding means (13,13a) in spaced apart position. Once the bottles
enter into the labeling unit (17), the folding means (13, 13) then help the sides
of the labels (14) folded onto the side surfaces of the caps (22) and the bottle neck.
[0025] In a subsequent step, the bottles (14) are conveyed to the rolling unit (16) which
then ensures that labels have firmly adhered to the side surfaces of the bottle caps
and bottle necks by applying pressure on said side surfaces with use of rollers. As
shown in Fig. 7, the rolling unit (16) is placed at a rear location of the labeling
tool (17) in the direction of the movement of the conveyor line. The rolling unit
(16) comprises enough number of roller which rotate around their own axis and which
apply sufficient on the labels from the side, thus ensuring firm adhesion of the labels
(14) on the bottle caps (22) and necks in part.
[0026] As shown in fig. 4, a label applicator delivers a label (14) on the top surface of
each bottle cap, the label then being only partly adhered to the cap. The label applicator
may be set to deliver a label such that one end of the label would be set sufficiently
long enough to reach the lower part of the bottle neck for the purposes of tamper
evidencing. Since the label in this case is not folded with an even distribution on
the left and right parts of the corresponding cap, an auxiliary folding member (19)
is used to fold the long end of the label properly on the side of the bottle neck.
The position of the auxiliary folding member (19) on the horizontal and vertical axis
can be set with the help of an adjustment device (24). The adjustment device (24)
is placed below one of said folding members (13,13a) and comprises one or more setting
screws (25). The setting screw(s) (25) is used to fix auxiliary folding member (25)
in a desired position.
[0027] Supporting structures (26) are provided for adjusting the position of the folding
means (13,13a) and hence the channel (18) formed in between. Fig. 5 shows the support
structures (26) which may be screw driven in order to adjust the position of the folding
members in the horizontal and vertical dimensions for fitting to the bottle height
and the cap width. Labeling tool (17) is a simple inexpensive mechanical device which
may be mounted easily and maintained as such.
