Description
[0001] The invention relates to a large package according to the
generic term of patent claim 1 or 2
[0002] Insulation products used in the construction trade, such as
in particular rock wool products in the form of panels or rolls,
are usually held in the form of packages comprising a stack of
superposed individual panels or panel packages or individual rolls
or modules comprising a plurality of rolls for the purpose of
transport and storage. These insulation products are products in
the bulk density range from 13 kg/m.sup.3 to 200 kg/m.sup.3. Since
in the construction trade, large areas usually have to be
insulated, comparatively large amounts of insulating material are
consumed for insulation purposes, so that there are problems in
transporting these voluminous rock wool products, consumed in large
quantities, to the customer and to the construction site.
Increasingly more, therefore, there has been a trend towards
packaging these rock wool products in large packages and providing
them with a wooden pallet. Such large packages are then transported
by their base by means of a fork-lift truck engaging in the pallet
or conveyed on the construction site by means of a crane to the
place of use, e.g. the roof. In particular on the construction
site, however, the emptied wooden pallets increasingly cause
problems as regards their disposal. Firstly, these must be
transported from the construction project, e.g. the roof, back to
the construction ground, and secondly, they must be disposed of
again from here.
[0003] For the purposes of transporting such packages or stacks, it
is therefore already known (EP 544 704 B) to wrap a film enveloping
the stack at one end in two layers in the form of a tab aligned
centrally with the stack, to weld it and provide adjacently located
handle openings in the welded tab. In this solution, the use of a
pallet is already eliminated as means of transport, since the
handle openings may serve for the engagement of a transport
device.
[0004] For large packages, which consist of a plurality of
adjacently arranged stacks, e.g. of fertiliser bags, it is already
known (PCT NO 97/00346), to use, instead of pallets, lifting eyes,
which are formed of the same material as the envelope of a
plurality of stacks. To this end, a fabric web is wound around e.g.
two stacks and, in the region of the separating plane of two
adjacently arranged stacks, is drawn upward over the top principal
surface of the envelope and inserted through a slit-like opening
introduced into the envelope, resulting in an eye-like handle loop
for the engagement of a means of transport. Apart from the fact
that, in this case, only one eye-like handle loop is provided,
problems occur for the handling of the large package by the means
of transport in particular by the fact that the handle loop must be
held up and held apart appropriately by additional auxiliary
personnel to allow engagement by the means of transport.
[0005] Furthermore, it is known, for the purposes of transport, to
provide large packages with a plurality of eye-like handle loops,
which are knotted from wrapping straps or wrapping cords, which,
however, is unfavourable in the case of rock wool products, because
straps of this kind cut in and therefore must usually be
additionally used with an underlying additional film web, which
increases the packaging outlay. Also, in the case of these straps
or strings, the same problem, in the region of the handle loop, of
difficult access by the means of transport, because these eyes must
be separately held up and held open, so that engagement by the
means of transport, for example the fork of a fork-lift truck, is
possible.
[0006] The object of the invention is to provide a large package
for transport and storage of insulation products, in particular
rock wool products in the form of panels or rolls, which can be
produced simply and at low cost and can be transported in a simple
manner without a pallet provided separately for each large package,
it being necessary to ensure reliable and rapid access for a
preferably conventional transport device, such as a fork lift
truck, for the purpose of transport of the large package.
[0007] This object is achieved according to the invention by means
of the features contained in the characterising part of claims 1
and 2, expedient further developments being characterised by the
features given in the subclaims.
[0008] According to the provisions of the invention, a multiplicity
of stacks are put together to form a large package, for example a
large package comprising two adjacently arranged stacks, each stack
containing, arranged one above the other, the rock wool products in
the form of individual panels or panel packages, and individual
rolls, or modules comprising a plurality of rolls, and at least one
eye-like handle loop being realised in the region of each stack.
The realisation of this eye-like handle loop may be formed by means
of a web which comprises fabric of high tensile strength or
sheeting of high tensile strength, which form the eye-like handle
loops per se, is laid on the principal surfaces of the adjacently
arranged stacks and is fastened to the wrapping of the stacks.
Herein, it is expedient if an eye-like handle loop is provided for
each stack. In the case of a large package comprising two stacks,
two eye-like handle loops are then available, which can then be
grasped, for example, by the fork tines of a fork-lift truck. The
overlaid web of fabric or sheeting is expediently of identical
material to the material of the wrapping which surrounds each
stack. It goes without saying that, within a large package, the
eyes are arranged at a distance from one another appropriate to the
means of transport.
[0009] According to another alternative embodiment, in which all
stacks of the large package are expediently jointly wrapped by a
single fabric web, the eye-like handle loops are realised by means
of a loop of the fabric web, which is guided through in the
separating plane of the adjacently arranged stacks, and is then
correspondingly wrapped around, or, by spreading out, is folded
over onto the principal surfaces of the stacks. In this case, just
as in the above-described embodiment, the eye-like handle loops may
be formed by the fabric web. Here, it is also possible in a very
simple manner to realise the eye-like handle loops with the
formation of the wrapping of the stack in one operation.
[0010] To prevent gaping open of adjacently arranged stacks, which
are combined into a large package, during transport by a lifting
means, it is expedient if the handle loops are arranged
eccentrically and offset towards the inside. This inevitably
results in a torque during the lifting of the large package, which
acts on each stack and forces it towards the separating plane.
[0011] The handle loops can expediently by designed so as to be
reinforced or stiffened by the insertion or mounting of
corresponding stiffening means. However, stiffening is also
possible by means of a multilayer realisation. A stiffening can
also be achieved by the fact that the web which is used for the
formation of the handle loops is gathered together and bound to
form a cord-like construction. By this means a comparatively
dimensionally stable handle loop is also formed, so that automatic
engagement by the transport means is possible without an auxiliary
person having to hold the handle loops.
[0012] In particular, each stack can advantageously be covered to
protect it against moisture, for example in that a trough-like,
watertight hood is arranged in the lower region of each stack and
can in particular expediently be accommodated within the envelope
comprising the fabric web or sheeting. Expediently the ends of each
stack can also additionally be covered with a fabric web or a
sheeting.
[0013] Preferred exemplary embodiments of the invention are
described below with reference to the drawing, wherein
[0014] FIG. 1 shows a schematic side view of a large package, which
is formed from two adjacently arranged stacks, and
[0015] FIG. 2 shows an analogous schematic side view of a further
embodiment of the large package, which also comprises two
adjacently arranged stacks.
[0016] In the embodiment according to FIG. 1, two stacks 1 and 2
are combined to form a large package generally designed 3. Each of
stacks 1 and 2 is formed from mutually superposed rock wool panels
along the principal surfaces. The number of mutually superposed
rock wool insulation panels is thereby chosen according to the
particular application, so that as many rock wool insulating panels
as required can be superposed. The rock wool panels within each of
stacks 1 and 2 are designated 4. Each of stacks 1 and 2 is wound
over its circumference with a web of fabric of high tensile
strength or of sheeting with high tensile strength, which is here
designated 5. Herein, it is possible to arrange each of stacks 1
and 2 in an envelope 5 comprising in each case an individual web of
fabric or sheeting; expediently, however, the envelopment of the
stacks 1 and 2 is carried out with one and the same fabric web,
which is wound such that it envelops each of the two stacks 1 and 2
to form an entirety. Envelopment techniques of this kind and well
known and it poses no difficulties to envelop both stacks here
entirely by means of a single web.
[0017] For the purpose of transport, a web, designated 6,
comprising fabric of high tensile strength or sheeting is arranged
on the package and can expediently be made of the same material as
the envelopment. According to the typical embodiment shown, the web
6 is arranged on the two upper principal surfaces of the stacks 1
and 2 and firmly connected to the envelope 5 of the two stacks 1
and 2 by adhesive bonding, welding or sewing or the like. In the
areas designated 7, however, the web 6 is not connected to the
envelope 5, but rather eye-like handle loops 8 and 9 are formed
there. This is achieved most simply in that the stretched textile
web 6 is pushed together somewhat in the regions 7, such that an
eye-like handle loop is formed automatically. If necessary,
however, to form the handle loops a mould core can also be used,
which is then removed again after adhesive bonding or welding of
the web 6 to the envelope 5, so that the eye-like handle loops 8
and 9 are formed.
[0018] In FIG. 1, an alternative embodiment is also shown, in which
the web 6, as shown in broken lines, is led around the top comers
of stacks 1 and 2, such that the fabric web 6 partially overlaps
the sides of stacks 1 and 2 at 10 and 11, which is advantageous for
a stable connection of the package. It goes without saying that the
web 6 is also fastened to the envelope 5 in the regions 10 and
11.
[0019] The eye-like handle loops 8 and 9 are, in the embodiment
according to FIG. 1, offset inwardly from the centre of each stack,
which is identified by the dotted plane 12, as is illustrated in
the left-hand stack 1 by plane 13, which is aligned approximately
centrally with the handle loop. This has the consequence that
whenever the package is lifted during transport by, for example, a
fork-lift, truck, a torque acting in a counterclockwise direction,
illustrated by the arrows D, acts towards the inside, such that the
two stacks are virtually forced together during lifting and cannot
gape apart. This is an expedient measure, which, however, is not
essential. In other words, the handle loops 8 and 9 may also be
arranged centrically, or even eccentrically towards the outer edges
of the stacks 1 and 2.
[0020] In the embodiment according to FIG. 2, a single fabric web
is used for the two stacks 1 and 2, the same components being
designated with the same reference characters. In this case it goes
without saying that, in the contact surface between the two stacks
1 and 2, two layers of the web 6 of fabric of high tensile strength
or sheeting, are present when each of stacks 1 and 2 is wrapped and
enveloped with a single layer of the web. In this case, as is
identified in FIG. 2 with a vertical arrow, the web 6 is drawn
upwards in the form of a tab-like loop during the wrapping of the
two stacks 1 and 2, the two loop halves 15 and 16 then being drawn
apart, as characterised by the arrows S. The left-hand loop half 15
is in this case, as for the transition phase, identified with a
broken line, laid towards the left on the principal surface of the
stack 1, the right-hand loop half, on the other hand, being laid on
the right-hand stack 2. This is again illustrated at the left-hand
side with the arrow T. The loop halves 15 and 16 thus therefore lie
on the top principal surface of the two stacks 1 and 2 and are
there fastened to the envelope 5, again with the formation of the
eye-like handle loops 8 and 9, which may suitably be carried out
by, for example, adhesive bonding, welding or stitching. It goes
without saying that, as a consequence of the folding, the web,
which then lies at the top, and forms the two eye-like handle loops
8 and 9, is now two-layered and consequently reinforced in design.
Here, too, the tab-like loop 14 may of course be drawn out until
the upper fabric web, which is again designated 6, also overlaps
the two edges of the stacks 1 and 2 analogously to the embodiment
according to FIG. 1, which is advantageous for reasons of
stability, depending on the weight of the package.
[0021] In a further embodiment, it is expedient that the handle
loops 8 and 9 are reinforced in design. In the embodiment according
to FIG. 2, this may take place in that a corresponding reinforcing
fabric is embedded between the two layers of each loop half 15 and
16 and, if appropriate, also firmly bonded to the fabric web 6.
However, it is also possible that, in the region of both handle
loops, but also expediently in adjacent regions, the fabric web 6
is gathered together and bound to form a cord-like construction,
resulting in cord-like handle loops. Finally, it may be expedient
that the sheeting serving to envelop the two stacks has
longitudinally extending reinforcements, virtually in the form of
"braces" in the sheeting, by virtue of which said sheeting does not
need to be as thick.
[0022] Depending on the intended purpose, it may be preferred to
envelop the two stacks 1 and 2 to form a weather-resistant entirety
by means of a sheeting or fabric, so that even the end surfaces,
which can be seen from the front in FIGS. 1 and 2, and the
rearwardly directed faces can be enveloped or covered with a
sheeting or fabric. As required, it is also possible for a
trough-like hood consisting of sheeting or fabric to be provided,
in particular in the lower region of each stack 1 and 2, which is
realised and designed as weather protection. This trough-like,
impermeable hood can then be received within the sleeve 5.
