Description

Description of the invention

The present invention relates in general to a transport block for the transport of heat-insulating panels 2, a method of forming such a block. More specifically, the present invention relates to such a transport unit that contains a package enclosed in a shell, and the package contains a stack of thermal insulation panels held by support elements, while the support elements and panels are made of a material used for thermal insulation, as well as to a method the formation of such a transport block.

The implementation of transport blocks for the transportation of thermal insulation panels is known in such a way that, in addition to the covering shell, they contain only materials intended for thermal insulation. Therefore, even the supporting elements used to hold the thermal insulation panels are made of the material used for thermal insulation. Thus, there is no need to use traditional cargo pallets, which eliminates the time-consuming manipulation of such pallets.

The transport unit of the type described in the introduction is described, for example, in document OE 4218354. 19 The described transport unit consists of a stack of thermal insulation panels located on two support elements. The supporting elements are made of the material used for thermal insulation, and they, together with the thermal insulation panels, are wrapped with a single packaging film to form a transport unit.

Accordingly, the transport unit manufactured in this way has great advantages compared to conventional transport units consisting of heat-insulating panels located on cargo pallets. When the transport unit is emptied, only the packaging film remains. Thus, complex and environmentally unfavorable manipulation of cargo pallets, which is expensive, is excluded.

However, the transport unit, which corresponds to document OE 4218354, is not without its shortcomings. One of the main disadvantages is that relatively expensive equipment is required for the formation of transport units of this type. In this context, it is necessary to make large capital investments, in particular, in the equipment used to wrap the supporting elements and the stack with packaging film to form the transport unit.

Another problem is related to the case when the heat-insulating panels forming part of the transportation sch 30 block are made of high-density material used for heat insulation. Such heat-insulating panels can be used, for example, for the construction of heat-insulated roofs. A transport unit containing thermal insulation panels of this type is relatively heavy and the transport unit will therefore need to be wrapped in several layers of packaging film to hold it together and maintain stability, which is a complex and time-consuming process.

Another problem is that the transport block of the known state of the art does not provide sufficient waterproofing. The reason is that the operation of wrapping supporting elements and heat-insulating panels with a packaging film is relatively difficult. This means that it is impossible to achieve that the packaging film, wrapped around the heat-insulating panels and supporting elements, reliably closes all sides of the transport unit facing the environment. Thus, when stored outside the Z 70 room, water can penetrate into the transport unit. It should be noted that in many cases transport blocks of this type are delivered to construction sites, where they are ready for use

From" are stored outside the premises.

The task of this invention is to create an improved transport unit of the above type and method of forming such a transport unit. 45 Another task is to create a transport unit, which, while providing the necessary lightness. manipulation, reliable watertightness can be provided, and which can be formed without the need to "drive" the use of expensive equipment.

Another task is to create a transport unit that can contain thermal insulation panels made of high-density material suitable for thermal insulation. page 20 In order to achieve these and other tasks, which will become clear upon reading the following description, a transport block is proposed, which corresponds to this invention, which has the distinctive features specified in clause 1 of the claims, as well as a method of forming the transport block, which has distinguishing features indicated in clause 14. Preferred variants of the transport unit that corresponds to the invention are shown in clauses 2-13, and preferred variants of the method that corresponds to the invention are shown in clauses 15-17 of the claims.

More specifically, the proposed transport unit containing a package taken in a shell, and

GF) the specified package contains at least one stack of heat-insulating panels held by support elements, while the support elements and said heat-insulating panels are made of a material suitable for providing thermal insulation, and the specified transport unit is distinguished by the fact that the shell covering the package, contains the first cover and the second cover, and the covers are put on the package, respectively, from its first side and from the opposite, second side, and the specified covers are connected to each other in the part along which one cover is superimposed on the other.

Thus, obtaining an environmentally acceptable transport block is ensured, which can be formed simply and quickly, without the need to use any complex and expensive equipment.

The transport unit is completely enclosed in a shell consisting of two covers, and thus has satisfactory water resistance. In addition, the connection between the two covers in the part where the covers are superimposed on each other can be strong enough to give the transport unit the strength necessary for manipulation, that is, it is held as a single unit during loading and unloading operations. It is especially preferable to use heat-insulating panels and support elements made of high-density material, such as pressed fibrous material, for example, glass or mineral wool, while the transport unit, thanks to the strength of the connection between the two covers, will be kept as a single unit during cargo transportation -unloading works without the risk of violating its integrity.

According to the preferred embodiment of the invention, the stack of the transport unit has, at least on one of its bearing surfaces, recesses for handling mechanical means of transport, such as forklifts, lifting equipment, etc. Preferably, these recesses are formed by niches in the multilayer panel, which is located under the stack and forms the specified support elements. Preferably, the multi-layer panel has a construction similar to that of a pallet, and has a width and length that substantially correspond to the width and length of the stack, with the recesses being made in the form of niches in the multi-layer panel that run continuously along the specified length. In particular, the multilayer panel can be formed from three protruding longitudinal /5 elements, between which there are niches, while the niches are formed by longitudinal elements of the multilayer panel with a lower height than the height of the protruding longitudinal elements.

According to another preferred embodiment of the transport unit according to the invention, the niches are obtained with the help of supporting elements in the form of a supporting body, which is made of a material identical to the material of the heat-insulating panels forming the stack, and which forms a section of the heat-insulating 2or panel of the stack or the heat-insulating panel of a smaller width in such a way that the support body, located in the center under the stack, will form on both sides of it notches for mechanical capture by the vehicle.

According to another variant of the invention, the support elements are located on the first side of the package, and the covers are located in such a way that in the indicated part, where the covers overlap one another, the second cover c is located outside the first cover. This ensures that the connection that is formed between the covers in the part where the covers overlap each other, will be oriented downwards, which means that the risk of water entering the bag i) through the connection is excluded.

According to another embodiment of the invention, the first and second covers are shrunk in such a way that they tightly fit the package. This tight fit in combination with the relative friction between heat-insulating panels ensures that the transportation blocks acquire the necessary stability.

Preferably, the first and second covers are made of plastic film, which is subjected to shrinkage with the help of heating. Ge

Preferably, the first and second covers are connected to each other in the part where the covers overlap each other by fusion. -

In addition, according to the present invention, a method of forming a transport unit is proposed, which includes the operations of placing support elements on the upper side of a stack of heat-insulating panels, and the specified heat-insulating panels and the specified support elements are made of the material used for heat insulation, and placing the package, made from the specified support elements and heat-insulating panels, into a shell to form the specified transport unit, while the specified method differs in that "the package is taken into the shell in the form of the first cover and the second cover, the first cover is pulled over the top of the package from 7-3 s of its first side , on which the supporting elements are located, and the second cover is pulled on top of the package from its . of the second side, located against the first side, the first cover and the second cover are connected to each other in a part, and? along which covers are superimposed on each other.

According to a preferred embodiment of the invention, the operation of pulling the second cover over the top of the package is preceded by the operation of turning the package over so that its second side is turned up. -I According to another preferred embodiment of the invention, the covers are made of plastic film, and each cover stretched over the top of the bag is shrunk by heat so that it fits snugly against the bag, while the second cover is connected to the first cover in the specified part, where the covers would overlap one another, by means of melting in combination with the shrinkage of the second cover.

Preferably, supporting elements, as well as thermal insulation panels, are made of high-density material used for thermal insulation.

Below, by way of example, preferred embodiments of the transport unit according to the invention will be described with reference to the attached drawings.

Fig. 1 is a schematic perspective view of the first embodiment of the transport unit, respectively

TO This invention.

Fig. 2-8 are schematic cross-sectional views showing the method of forming the transportation block (F, shown in Fig. 1. and Fig. 9 are schematic cross-sectional views of the second version of the transportation block according to this invention. 60 Below will be two embodiments of the present invention are described with reference to the attached drawings, in which similar parts are assigned the same reference numbers.

Figure 1 shows the first preferred embodiment of the transport unit 1 according to the present invention.

The transport unit 1 contains a package 3, taken in a shell 2. Package C contains a stack 5 of heat-insulating 65 panels 6, which is held by two support elements 4 and is shown by dashed lines in Fig.1. Both supporting elements 4 and thermal insulation panels are made of material used for thermal insulation,

such as pressed glass or mineral wool.

The shell 2 contains the first cover 7 and the second cover 8, which are put on the bag C from its opposite sides 9, 10. The covers 7, 8 are made of plastic film and fit tightly to the bag 3.

Covers 7, 8 are adapted to form a part 11 that runs along the perimeter, along which they overlap one another. The covers 7, 8 are attached to each other by means of a connection 15 in this part 11, where the covers overlap one another, and the connection 15 is shown as a gray shaded area. Preferably, the connection 15 passes through the entire part 11, where the covers overlap one another. The package C is completely closed by two covers 7, 8, which make up the shell 2. Thus, the transportation unit 1 is obtained, which can be formed without the need for the use of complex equipment used in the usual wrapping of the package 3. Only the equipment for putting on the two covers is needed 7, 8 from opposite sides 9, 10 of package 3, as well as equipment for connecting covers 7, 8 in the part where they overlap one another.

Due to the fact that the package C is completely closed by two covers 7, 8, which make up the shell 2, /5, a satisfactory watertightness is ensured.

The tight fit of the shell 2 to the package C in combination with the relative friction between the heat-insulating panels 6 gives the transport unit 1 the necessary stability.

The connection 15 in the part 11, where the covers overlap one another, can be strong enough to ensure that the transport unit 1 will be kept as a single entity during 2o loading and unloading operations without the risk of breaking its integrity.

The covers 7, 8 are located in such a way that in the part 11 running along the perimeter, where the covers overlap one another, the second cover 8 is located outside of the first cover 7. This ensures that the connection 12 in the part 11, where the covers superimposed on each other, will be oriented downwards, as shown in the figure. Thus, when the transport unit 1 is exposed to moisture, the accumulation of water in the part 11 where the covers are superimposed can be eliminated, which means that the risk of moisture entering the transport unit 1 through the part 11 where the covers are superimposed on the other, it is excluded. and)

Below, with reference to Fig. 2-8, the method of forming the transport unit 1 shown in Fig. 1 will be described.

Fig. 2 shows a stack 5 of thermal insulation panels 6, made of material used for thermal insulation.

As shown in Fig.3, two supporting elements 4 are placed on the upper side of the stack 5. These supporting elements 4 are made of the same material as the thermal insulation panels 6, and thus they can be used together with the latter for thermal insulation. Support elements 4 form package C together with a stack 5 of thermal insulation panels 6, while support elements 4 are located on the first side 9 of package 3.

Fig. 4 shows how the first cover 7 is located on the package 3. More specifically, the first cover 7 is pulled over the top of the package C from its first side 9. According to the preferred embodiment of the invention, the cover 7 is preferably made of a plastic film, which can be shrunk by heat.

The first cover 7 is then shrunk in such a way that it fits snugly against the bag 3, and in Fig. 5 the cover 7 is shown slightly removed from the bag C for clarity. As for the specified in the planting, it ensures that the support element 4 is fixed relative to the stack 5. Preferably, the planting is carried out with the help of c heating.

Then the package C is turned over so that its first side 9 is turned down, and its opposite ;" side 10 was turned upwards as shown in Fig.b.

Fig. 7 shows how the second cover 8 is located on the package C. More specifically, the second cover 8 is pulled over the package C from its second side 10. According to the shown variant of the invention, the second cover 8 is preferably also made of plastic heat-shrinkable film.

Covers 7, 8 are adapted to form part 11, along which they overlap one another. ve Finally, Fig. 8 shows how the second cover 8 is stretched for its close fit to the package 3, and the second cover 8 is also shown slightly removed from the package C for clarity. Again, shrinkage can be achieved by heating. According to the shown embodiment of the invention, the specified heating 1 is regulated in such a way that the covers 7, 8 melt together and bond with each other throughout the part 11, where

They overlap, thus forming a connection 15 between covers 7, 8.

Due to the location of the second cover 8 outside of the first cover 7 in the part 11, it is ensured that the connection 12 formed in the part where the covers overlap each other will be oriented downwards, which means that the risk of water ingress into the package C through part 11, where the covers are superimposed on each other, is excluded.

Thus, the transportation unit 1 is obtained, which is completely covered by the shell 2, and which, in addition, (F) has the necessary stability and provides ease of manipulation. In this regard, it is the strength of the connection ka 15 between the covers 1, 8 in combination with the own strength of the covers 7, 8 and their tight fit to the package C that provides the necessary stability of the completed transport unit 1 and ease of handling it. It has been found that the transport unit 1, according to the invention, is particularly preferred for packages 3, which contain only one stack 5 of thermal insulation panels 6. However, it will be understood that the package may also contain several stacks, and the support elements in the case where the package contains two stacks, can be arranged in such a way that each stack is held by a corresponding support element and an additional support element that is divided into two stacks. 65 The transport unit 1, according to the invention, turned out to be particularly advantageous for a package 3 containing a stack of heat-insulating panels 6 made of high-density material. According to the prior art,

it was found difficult to enclose transport units containing such thermal insulation panels.

Due to the large weight of the transport unit, it was necessary to wrap the package with many layers of packaging film, so that the transport unit formed in this way was kept as a whole and maintained its stability.

Which is a complicated and time-consuming process.

According to the present invention, the transport unit 1, instead, is covered by a shell 2, consisting of two covers 7, 8, which are stretched, preferably tight on the package C from its opposite sides 9, 10.

It is a relatively simple operation that can be performed quickly, using only simple equipment.

Covers 7, 8 are connected in part 11, where they overlap one another. Unexpectedly, the joint 15 formed in this way 70 turned out to be strong enough to be held by the two covers 7, 8, which make up the shell 2, of the transport unit as a single unit during further manipulation, and thus the transport unit remains stable and convenient to handle . The strength of the connection 15 can be adjusted by changing the length X of part 11, where the covers overlap one another.

The tests showed that the length X of part 11, where the covers are superimposed on each other, should be 7/5 within 200-500mm, preferably within 300-400mm for a transport unit with dimensions of 2.4mx1.2x1.3m and a weight of approx. 400 kg. Such a transport unit 1 can contain a package of heat-insulating panels b made of high-density material, while each heat-insulating panel b has a maximum thickness of 500mm. Heat-insulating panels of this type are particularly suitable for the construction of heat-insulated roofs.

The strength of the connection 15 in part 11, where the covers are superimposed on each other, and the inherent strength of the two covers 7, 8 ensures that the transport unit 1 is kept as a single unit during its manipulation without violating its integrity. In addition, the tight fit of the shell 2 to the package C in combination with the relative friction between the heat-insulating panels 6 ensures that the transport unit 1 has the necessary stability.

Figure 9 shows the second embodiment of the transport unit 1 according to the present invention. high school

This variant is intended for the formation of particularly heavy transport blocks 1. This variant of the implementation of the invention differs from the variant described with reference to Fig. 1-8 in that the support elements 4 are slightly i) offset from the edges of the first side 9 of the package C, and the length X part 11, where the covers overlap each other, is enlarged so that it now also covers the edges 13 formed between the first side 9 of the package C and the sides 14 connected to it. As before, the covers 7, 8 are connected to each other along the entire part 11, where they overlap each other, and this can be achieved, for example, by shrinking the second cover 8 by heating so that it bonds and fuses with the first cover 7 in the part 11, where covers that) overlap one another. The increased length X of the part 11, where the covers overlap each other, and the fact that the part 11 now covers the edges 13 formed between the first side 9 of the package C and the sides 14 of the package communicating with it 3 make a connection 15 between the covers 7, 8 are very strong and, thus, the transport unit is particularly suitable for the transport of heat-insulating panels made of high-density material.

Thus, according to the present invention, a transport unit 1 containing a package C is obtained, which is completely covered by a shell 2 consisting of two covers 7, 8. Two covers 7, 8 are put on with a tight fit on the package C from its opposite sides 9 , 10 and with an overlay along part 11, in which two covers 7, « 8 are connected to each other. The transport unit 1 obtained in this way can be easily and quickly formed 2 s without the need to use expensive equipment, while the shell 2 and, in particular, the connection formed between the covers 7, 8, has sufficient strength to manipulate the transport unit 1 without risk of violation;" its integrity. In practice, the shell 2 can be made strong enough to be held by the transport unit 1 of the package 3 containing thermal insulation panels made of high density material suitable for thermal insulation. Examples of preferred high density materials are compressed fibrous materials such as -I pressed glass wool which can have a density in the range of 80-17Okg/m 3 or pressed mineral wool which 1» can have a density in the range 100-20Okg/m? . High-density materials of this type can be used, for example, for thermal insulation of roofs. (o) Since the supporting elements 4, forming part of the package 3, are preferably made of a high-density material sl 50 of the type described above, their load-bearing capacity will be satisfactory, which means that they will be less likely to be deformed, holding the heat-insulating panels 6 located on them. k) It will be clear that the present invention is not limited to the shown variants of its implementation.

For example, it may be envisaged to obtain the specified compound in other ways, for example, by means of heating using heating elements.

In addition, the support elements 4 can be located in different ways. Moreover, it is preferable that the stack 5 forms recesses 16 in at least one of its bearing surfaces, such as the lower side 9, for manipulation by mechanical means of transportation, such as forklifts, lifting equipment, etc. It is preferable that the recesses 16 form the support elements 4, for example, as shown in Fig.1.

According to a preferred embodiment of the invention (not shown), the specified recesses form the niches 60 of the multilayer panel, which is placed under the stack, thus forming the specified support elements.

A multi-layer panel should be understood as a panel consisting of multiple layers of pressed mineral wool, which, for example, are glued to each other, and the specified layers follow one another and are oriented essentially perpendicular to the plane of the panel.

The multi-layer panel can be made in a pallet configuration and can have a width and length that essentially 65 correspond to the width and length of the stack. In addition, the multilayer panel is preferably formed from three protruding longitudinal elements, between which niches are formed. These niches, preferably, form longitudinal elements having a lower height than the specified protruding longitudinal elements.

According to another preferred embodiment of the invention (not shown), the transport unit, according to the invention, has support elements in the form of a support body, which is located in the center under the stack. The support body is made of material identical to the material of the thermal insulation panels in the stack, and it has a width that is less than the length of the stack, with the help of which the support body limits the sides formed on both sides of it by notches for mechanical capture by means of transportation.

Accordingly, several modifications or variants can be considered and the present invention is thus limited only by the appended claims.
