[0001] The present invention relates to a palletizing system or pallet of bundles of tubes
and the relative formation method.
[0002] More specifically, the invention relates to a palletizing system or pallet of bundles
of tubes for industrial, electric, electronic and electro-technical applications,
comprising a series of tubes packed in bundles and the relative formation method.
[0003] Palletizing systems of materials have long been used for allowing the packaging and
storage of pallets by stacking and at the same time for simplifying their transportation.
[0004] Rigid tubes for the protection of wiring are known in the field of industrial applications
in general, and in particular in the field of electrical, electronic and electro-technical
applications. Said tubes are cut into a standard size, for example 3 metres, packed
in bundles comprising various units of tubes and subsequently placed in wooden frames
fixed with nails or clips.
[0005] A pallet according to the known art is, for example, produced with tubes inserted
in three substantially equidistant frames; the tubes are finally bound by means of
a metallic strap.
[0006] A palletizing system or pallet according to the known art is illustrated in figure
1, after its opening.
[0007] Figure 1 indicates the bundles 2 of tubes 3 produced by wrapping the tubes with a
plastic film 4, the bundles 2 are stacked to form a package 5 and are inserted in
frames 6 made up of wooden boards 7 joined by means of nails or metallic clips 8.
[0008] The package is secured by binding with a metallic strap 9.
[0009] As can be seen in figure 1, the frames must be literally split open to be able to
use the tubes. This operation not only creates risks for the operator himself, but
also causes the inevitable dispersal of wood splinters, nails and metallic strap which
are difficult to recover and can cause damage and wounds when there is a lack of personal
protective means or, in any case, safety problems with respect to the staff and clients.
[0010] Another disadvantage of the known system described above is that it produces significant
volumes of packaging material which cannot be re-used.
[0011] The main objective of the present invention is consequently to overcome the above
drawbacks of the known art by providing a palletizing system or pallet which is simple
to produce, does not envisage the use of nails and metallic strap and which allows
the components to be re-used.
[0012] Another objective of the present invention is to provide a pallet which has a high
sturdiness and resistance for optimizing the moving, transportation and storage logistics
of the pallets of tubes.
[0013] Also included in the objectives of the present invention, is the production of a
pallet having a high resistance to transportation and stacking conditions so as not
to cause deformation or twisting in the single tubes.
[0014] The palletizing system according to the invention advantageously avoids the presence
of protruding nails, clips or metallic strap when opening the pallets.
[0015] These and other objectives according to the present invention are achieved by the
self-supporting palletizing system or pallet of bundles of tubes according to what
is specified in claim 1.
[0016] A method for the production of a self-supporting palletizing system of tubes according
to the present invention is the object of claim 10.
[0017] Further characteristics of the invention form the object of the dependent claims.
[0018] The self-supporting and stackable palletizing system or pallet of bundles of tubes,
in particular tubes for industrial, electrical, electronic and electro-technical applications
according to the invention, comprises a series of tubes packed in self-supporting
bundles with a polygonal section neatly arranged to form a package of tube bundles
positioned on a series of supporting beams, the palletizing system also comprising
a series of simple beams each situated above the package in correspondence with each
supporting beam, and flexible means suitable for binding the beams and the package
and compressing it.
[0019] The characteristics and advantages of a self-supporting palletizing system or pallet
of bundles of tubes, in particular tubes for industrial, electrical, electronic and
electro-technical applications, according to the present invention, will appear more
evident from the following illustrative and nonlimiting description, referring to
the enclosed schematic drawings, in which:
figure 1 is a perspective view of various pallets according to the known art;
figure 2 is a schematic side view of the palletizing system according to the invention;
figure 3 is a schematic view of the end of the system of figure 2;
figure 4 is a schematic view of the end of a bundle of tubes of the package of figure
3;
figures 5 and 6 are schematic perspective views of details of the system of figure
2;
figure 7 is a perspective view of a detail of the palletizing system according to
a different embodiment thereof.
[0020] With reference to figures 2 to 6, these illustrate a palletizing system or pallet
10 of bundles 12 of tubes, in particular tubes 13 for industrial, electrical, electronic
and electro-technical applications.
[0021] The system according to the embodiment of the invention therefore comprises a series
of tubes 13 packed in bundles 12 with a polygonal section by wrapping with a plastic
film 14.
[0022] The bundles 12 thus formed are suitably and neatly arranged to form a self-supporting
package 15 of bundles of tubes, having an overall substantially square section, positioned
on a series of supporting beams 16.
[0023] The palletizing system or pallet 10 also comprises a series of simple beams 17 each
positioned above the package 15 in correspondence with each supporting beam 16.
[0024] The system is completed by closure with flexible means 18 destined for binding the
package by wrapping the beams 16, 17 and the package 15, so that these flexible means
18 compress the package 15, laterally.
[0025] Said flexible means 18 consist of a strap, preferably made of a plastic material,
which, thanks to its elastic properties, allows a greater traction in the closing
phase of the bundles 12 of tubes 13, without, however, causing the deformation of
the tubes 13 but allowing a firmer binding of the beams 16, 17 and package 15, thus
allowing a structurally securer and sturdier pallet 10 to be obtained.
[0026] This firmer binding is also obtained thanks to the fact that the bundles 12 of tubes
13 are produced in suitable polygonal forms in relation to their diameter, by means
of specific industrial equipment, and are arranged and suitably oriented so as to
form a self-supporting package.
[0027] In this way, the tubes are not deformed as the self-supporting package 15 and beams
allow a better distribution of the traction of the strap giving the finished palled
greater strength.
[0028] The supporting beams 16 are equipped with a prop 19 situated below each of their
ends, to favour the moving and stacking of the pallets 10.
[0029] The supporting beams 16 and also the simple beams 17 are generally produced with
a shorter length than the width of the package 15 so that they do not protrude, to
prevent the stacking of the pallets 10 from being too encumbersome as well as difficult
and unstable, in particular when the pallets have different heights.
[0030] It should be remembered, in fact, that the dimensions of the pallets are calculated,
for obvious logistic reasons, bearing in mind the useful loading width and height
of the transport vehicles in order to maximize the number of tubes which can be transported
per volume unit, in order to reduce transport costs.
[0031] With reference to figure 7, it is possible, however, to produce supporting beams
16 with dimensions greater than the width of the package 15, i.e. protruding with
respect to its head section, in this case, there is a groove 20 at both outer ends
of the supporting beams and props 19 for housing the strap 18 so that this can still
exert its compressing function of the package 15 and pallet 10 in general.
[0032] The supporting beams, simple beams and props are suitably made of wood, other economically
and technologically valid materials, however, can also be advantageously used in view
of the possibility of recovering and re-using them for the production of new pallets
10.

c) placing a simple beam 17 above the package 15 in correspondence with each supporting

d) winding and firmly binding a suitable length of strap 18 around each pair of simple
beam 17, supporting beam 16, with the package 15 of tube bundles in-between so that
said flexible means 18 laterally compress the package 15.
