Description
METHOD DISCLOSED BY THE INVENTION
[0001] The present invention relates to a method for applying a
plastic film around a product to be packaged, according to which
method
[0002] the product to be packaged is moved to a position inside a
plastic film girdle of shrinkable and/or stretchable plastic placed
on a supporting frame consisting of supporting elements and having
a circumference larger than the circumference of the product to be
packaged, or correspondingly the plastic film girdle is moved to a
position surrounding the product to be packaged,
[0003] whereupon the supporting frame consisting of supporting
elements is removed from inside the plastic film girdle, with the
result that the plastic film girdle is tightened around the product
to be packaged.
PRIOR ART
[0004] A method for applying a plastic film around a product to be
packaged is presented in Specification U.S. Pat. No. 4,454,705,
wherein a plastic film girdle of shrinkable plastic is placed on a
supporting frame and the product to be packaged is brought to a
position inside the supporting frame. When the supporting elements
of the supporting frame are removed, the plastic film girdle is
tightened around the product. However, this method is not
sufficiently efficient when it is necessary to get several products
packaged in a short time. In addition, plastic film girdle has to
be of a suitable size corresponding to the product to be
packaged.
[0005] Another alternative for applying a plastic film around a
product to be packaged is to bring the product to the wrapping
station of a wrapping packaging machine, where the product to be
packaged is held stationary while wrapping packaging film is
wrapped around the product from a film reel circulating about the
product. An essential feature of the prior-art wrapping method is
that the product to be packaged remains stationary during the
wrapping operation and the wrapping line is halted each time for as
long as it takes to wrap up the product. The duration of the halt
is additionally increased by the starting actions and the seaming
and cutting of the wrapping film band associated with the wrapping
operation. However, in practice it is important that the capacity
of the packaging method used should be as high as possible to
enable the products to be packaged to be passed through the
packaging stage as quickly as possible.
OBJECT OF THE INVENTION
[0006] The object of the present invention is to overcome the
above-described drawbacks and achieve a new and faster method for
applying a wrapping plastic film around an object A specific object
of the invention is to achieve a method for creating collars or
girdles around a product to be packaged. Collars or girdles can
also be made from wrapping plastic film, and these have numerous
advantages as compared to prior-art girdles formed from steel or
hard plastic bands, because a girdle formed from wrapping plastic
film is softer and more resilient. It requires no corner supports
to be used in conjunction with it and yet it does not damage the
edges of the product to be packaged. However, producing a girdle by
means of a wrapping packaging apparatus is a slow and uneconomical
method as each girdle has to be wrapped separately.
FEATURES OF THE METHOD OF THE INVENTION
[0007] The method of the invention is characterized in
[0008] that the plastic film girdle is formed by wrapping
shrinkable and/or stretchable wrapping plastic film band to form a
plastic film girdle around the supporting frame consisting of
supporting elements and having a circumference larger than the
circumference of the product to be packaged,
[0009] that the product to be packaged and/or the plastic film
girdle are/is moved so that the product to be packaged remains
inside the plastic film girdle,
[0010] and that the supporting frame consisting of supporting
elements is removed from inside the plastic film girdle and the
plastic film girdle is allowed to tighten around the product to be
packaged.
EMBODIMENTS OF THE METHOD OF THE INVENTION
[0011] A preferred embodiment of the invention is characterized
in
[0012] that the plastic film girdle is formed by wrapping a
wrapping plastic film band around the supporting frame consisting
of supporting elements
[0013] that the wrapping plastic film band supplied to form the
plastic film girdle is severed and, if necessary, seamed,
[0014] that the product to be packaged and/or the plastic film
girdle are/is moved on a track so that the product to be packaged
remains inside the plastic film girdle,
[0015] and that the supporting frame consisting of supporting
elements is removed from inside the plastic film girdle and the
plastic film girdle is allowed to shrink and tighten around the
product to be packaged.
[0016] Since the plastic film to be wrapped consists of either
stretched plastic film or tightened or otherwise shrinkable
stretched plastic film in conjunction with the wrapping carriage,
the film girdle will shrink and tighten around the product to be
packaged when it is transferred onto the surface of the product to
be packaged. The tightening force can be adjusted by suitably
selecting the plastic film and/or its pre-stretching.
[0017] According to the invention, during the wrapping operation
the girdle to be produced by wrapping is most preferably located
outside the product to be packaged, at a distance from it. However,
the girdle to be produced by wrapping need not be aligned with the
product to be packaged. Preferably the products to be packaged can
be moved on the track so that the area on the product where a
wrapping or bandage is to be formed comes into a position aligned
with the girdle, whereupon the girdle is transferred onto the
product.
[0018] A second preferred embodiment of the method of the invention
is characterized in
[0019] that wrapping film band is wrapped over the supporting frame
consisting of supporting elements, thus forming a film girder tube
on the supporting frame,
[0020] that a plastic film girder of desired length is cut off the
film girder tube,
[0021] that the product to be packaged and/or the plastic film
girder are/is moved on the track so that the product to be packaged
remains inside the plastic film girder cut off,
[0022] and that the supporting frame consisting of supporting
elements is removed from inside the plastic film girder and the
plastic film girder is allowed to shrink and tighten around the
product to be packaged.
[0023] A third preferred embodiment of the method of the invention
is characterized in
[0024] that wrapping film band is wrapped over the supporting frame
consisting of supporting elements in a continuous manner so that a
film girder tube continuously increasing in length is formed on the
supporting frame,
[0025] that a plastic film girdle of desired length is cut off the
plastic film girdle tube during the wrapping operation
[0026] that, while the wrapping operation is being continued, the
product to be packaged and/or the plastic film girdle is moved on
the track so that the product to be packaged remains inside the
plastic film girdle cut off,
[0027] and that the supporting frame consisting of supporting
elements is removed from inside the plastic film girdle and the
plastic film girdle is allowed to shrink and tighten around the
product to be packaged.
[0028] The continuous method is very fast and efficient because the
wrapping packaging machine can be continuously in operation,
producing wrapped tube, from the end of which a girdle of suitable
width is cut off, which girdle then tightens around the product to
be packaged that comes to the appropriate position while advancing
on the track.
DEVICE OF THE INVENTION
[0029] The invention also relates to a device for applying a
plastic film around a product (16) to be packaged, said device

packaged and/or the plastic film girdle so that the product to be
packaged remains inside the plastic film girdle,
[0032] means for removing the supporting elements from inside the
plastic film girdle, allowing the plastic film girdle to tighten
around the product to be packaged.
FEATURES OF THE DEVICE OF THE INVENTION
[0033] The device of the invention is characterized in that the
device comprises
[0034] a wrapping system for wrapping a shrinkable and/or
stretchable plastic film band from a film reel over the supporting
elements so that the wrapping film band being wrapped forms on the
supporting elements a plastic film girdle tightening over the

[0035] and transfer elements for transferring the product to be
packaged and/or the plastic film girdle formed from the wrapping
plastic film band so that the product to be packaged remains inside
the plastic film girdle,
EMBODIMENTS OF THE DEVICE OF THE INVENTION
[0036] A preferred embodiment of the device of the invention is
characterized in
[0037] that the supporting elements of the device, on which the
wrapping plastic film band can be wrapped to form a plastic film
girdle, form a preferably rectangular supporting frame whose width
and height are larger than the width and height of the product to
be packaged,
[0038] and that each corner of the supporting frame consisting of
supporting elements is provided with at least one supporting
element, which can be moved to transfer the plastic film girdle to
a position around the product to be packaged.
[0039] A second preferred embodiment of the device of the invention
is characterized in that the device has at the corners of the

DESCRIPTION OF THE FIGURES
[0058] FIG. 1 presents a side view of a wrapping machine 10
according to an embodiment of the invention, comprising a track 11
and a rotating ring 12. Attached to the track 12 is a film
dispensing carriage, which is provided with a film reel 14
containing wrapping plastic film 15. Placed on top of the product
16 to be packaged moving on the track 11 are transverse pieces 17a
and 17b to facilitate later manipulation of the product, said
pieces being bound in the same bundle with the product 16 itself by
means of girdles to be produced by wrapping.
[0059] The wrapping machine 10 in FIG. 1 is provided with a
wrapping support system 20 comprising four supporting elements
21a-21d, which can be turned about axles 23a-23d and which are
located on either side of the track 11 and therefore of the product
16 to be packaged. All the supporting elements 21a-21d have
straight sides 22a-22d, which in the wrapping position shown in
FIG. 1 together form a supporting frame, on which the film girdle
18 to be produced from plastic film 15 by wrapping can be
formed.
[0060] In the situation illustrated in FIG. 1, the wrapping
operation for producing a film girdle 18 is going on. However, the
product to be packaged 16 is not yet aligned with the girdle 18
because, according to the invention, the girdle 18 can be finished
beforehand and only then transferred onto the surface of the
product 16. As shown in FIG. 1, the product to be packaged 16 is
placed on the track 11 and moving towards the wrapping station 20.
By using adjusting elements comprised in the device, the supporting
frame consisting of supporting elements 21a-21d has been adjusted
to be larger than the product 16 to be packaged, so that the film
girdle 18 being produced will be large enough to allow the product
16 being packaged to be moved inside the film girdle supported by
the supporting frame.
[0061] In FIG. 2, the wrapping operation producing a film girdle 18
has been completed. The films forming the film girdle 18 supported
by the supporting elements 21a-21d have now been seamed and the
plastic film band coming from the reel 14 has been severed.
However, the plastic film band need not always be seamed if the
film band layers placed one over the other are otherwise held fast
on each other sufficiently well. At the same time, the product 16
to be packaged has moved on the track 11 so that transverse piece
17a is aligned with the film girdle 18 in the wrapping station 20.
The ring 12 and film dispensing carriage 13 connected to it have
been stopped for a short while, during which the film girdle 18 is
transferred onto the product 16 to be packaged and the transverse
piece 17a, as illustrated in the next FIGS. 3 and 4. The end of the
film band 15 coming from the film reel 14 is held fast by a gripper
24 and is ready for the start of a wrapping operation for producing
the next film girdle.
[0062] In FIG. 3, the transfer of the film girdle 18 onto the
product 16 to be packaged and the transverse piece 17a has been
started by having the supporting elements 21a-21d turned about the
axles 23a-23d, the film girdle 18 formed from stretched film 15 can
now descend onto the product 16 and tightens over the transverse
piece 17a and the product 16 to be packaged so that these become
bound together by the girdle 18.
[0063] In FIG. 4, the film girdle 18 has been tightened over the
product 16 to be packaged and the transverse piece 17a the
supporting elements 21a-21d have been turned about the axles
23a-23d to their outermost position, so the film girdle 18 has been
able to be transferred onto the surface of the product 16 to be
packaged. In this situation, the formation of the film girdle 18
has been completed and the supporting elements 21a-21d begin to
turn again to the position of readiness shown in FIG. 1 and a ready
for the next film girdle wrapping operation. Therefore, the
rotating motion of the ring 12 can be quickly started and the
wrapping operation for forming the next film girdle, which is to be
wrapped over transverse piece 17b, can be started immediately. The
product 16 to be packaged also starts moving and is again at the
right position on the track 11 when the next film girdle is ready
to be mounted.
[0064] FIG. 5 presents a wrapping machine 10 according to the
invention as seen from the direction of the track 11. A wrapping
operation for forming a film girdle around a product 16 to be
packaged has just been started. The end of the plastic film band 15
coming the film reel 14 is held in the gripper 24 and the ring 12
has rotated through a nearly full revolution. During the second
revolution, the end of the wrapping plastic film band 15 can be
released from the gripper 24 because the film layers wrapped upon
each other stick together. After that, the wrapping action for
forming a film girdle is continued until the number of layers of
film 15 is e.g. three.
[0065] In FIG. 6, three layers of wrapping plastic film band 15
have been wrapped one upon the other. The ring is now stopped again
for a short while and the seaming and cutting device 25 seams the
wrapping plastic film layers to form a dosed film girdle 18. At the
same time, the gripper 24 grips the plastic film band 15 coming
from the reel 14 so that it will be ready for the start of the
wrapping operation for forming the next film girdle.
[0066] In FIG. 7, the seaming and cutting device 25 has released
its grip and the film girdle 18 is continuous and ready to be
transferred onto the product 16 to be packaged. In FIG. 7, the
supporting elements 21a-21d move in the directions indicated by the
arrows, allowing the film girdle 18 to tighten around the product
16 to be packaged and over the transverse piece 17.
[0067] FIG. 8 presents the wrapping support system 20 of the
wrapping machine of the invention according to a second embodiment.
In this embodiment, the wrapping support system 20 is simpler than
in the example illustrated in the previous figures because it
comprises only two supporting elements 21a-21b on either side of
the product 16 to be packaged. In such a structure, the film girdle
18 is transferred onto the product 16 to be packaged in a lopsided
manner with one edge first. The device works just as well, at least
if the product 16 to be packaged is heavy. In the case of lighter
objects, it is preferable to use during the transfer of the film
girdle a clutch known in itself, which presses the product 16 to be
packaged from above, thus holding it reliably in place. The clutch
is not shown in the figures.
[0068] In the embodiment presented in FIG. 9, the supporting
elements 21a-21b in the wrapping support system 20 of the wrapping
machine are endless belts, over which the film girdle 18 is
wrapped. The finished film girdle 18 is cut off by means of a
clipper 26 and transferred onto the product 16 to be packaged by
means of second endless belts forming extensions of belts 21a-21b
in the manner illustrated in FIG. 9. In this case it is preferable
to have also the product 16 to be packaged simultaneously moving in
the direction indicated by the arrow, thus accomplishing continuous
mounting of plastic film girdles around the products to be
packaged.
[0069] FIG. 10 presents yet another embodiment of the wrapping
machine of the invention, in which the supporting elements 21a-21d
in the wrapping support system 20 are rotating bars, over which the
wrapping plastic film 15 is wound from the film reel 14. The film
reel 14 and the bars 21a-21b are so disposed with respect to each
other as to also allow a continuous wrapping action for forming a
film girdle 18 over the bars 21a-21b, the product thus obtained
being a plastic film tube 18b, which is cut off by means of a
clipper 26 to form a film girdle 18a of suitable length. As the
bars 21a-21b are rotating, the film girdle 18a cut off advances to
the right in FIG. 10 and is first transferred onto second reels and
then onto the product 16 to be packaged.
