Description

DESCRIPTION REPORT PACKAGING SYSTEM FOR ELECTRICAL INSULATORS Field of innovation

[001] The present innovation belongs to the field of packaging systems for electrical insulators, more specifically of a packaging system that comprises a set of packages of octagonal straight prismatic configuration that are crimped together in order to form a stable structure.

Innovation history

[002] The transport of electrical insulators comes up against the difficulty of protecting sensitive elements, built with such friable materials as glass or porcelain. Therefore, their packaging must provide maximum protection while allowing for handling, stacking and movement. [003] The current practice uses straight square prismatic boxes, formed by an association of wooden slats fixed together, which allow them to be piled on a pallet and the lashing of the set for stabilization.

[004] However, such a solution does not withstand movement during transport, especially the more rigorous one, causing damage to the structure, loosening the fastenings and, consequently, jeopardizing the integrity of the insulators.

[005] With the objective of optimizing material resources, in the use of packaging, and minimizing costs with sea and land freight, the idea arose of creating packaging with less material used, however, with a focus on ensuring the integrity of the materials contained in them. .

[006] To verify its possible implementation, prototypes were made and some loads were assembled. Then, handling, movement, external transport and storage tests, according to the ABNT NBR 8604 Standard, in addition to stacking and truck transport tests were carried out, totaling 4,800 km round trip. After the return of the loads, their conditions were analyzed thoroughly, and no damage was found to the packaging or contents.

[007] The application of this packaging model, compared to the one currently used, reduces logistics costs by around 20% and, in terms of materials used, the reduction can exceed 40%. So, the solution proposed here not only makes it possible to meet the needs of packaging and transporting items, but is also more efficient in terms of manufacturing; in the optimization of material resources, since it uses fewer elements in its construction; in logistics optimization, as it allows a better use of space when compared to current solutions; allows assembly in production line; and has more structural stability compared to current solutions. [008] Still, when considering the use of fumigated wood for its construction, it uses much less wood, significantly reducing the generation of contaminated tailings.

[009] Thus, the solution of the present innovation comes to present a system of stable and resistant packaging, allowing the safe movement of electrical insulators conditioned in octagonal straight prismatic packages that can support each other and allow stability to the formed set.

Discussion of the state of the art

[010] Document US9346585 shows scalable, modular and side and vertically lockable devices and containers with other similar containers for a variety of applications, the container being formed by a wall attached at the first end to an upper end section with an opening and fixed at a second end by a lower end section, with one or more tongues formed in the wall, having an interconnection mechanism to be received and interconnected by a groove, the vertical interconnectivity being carried out with mechanisms for stack containers and avoid turning using a channel and christian interlocking arrangement.

[011] Patent JP20180033487 discloses a battery module that includes a plurality of batteries and at least one spacer disposed between adjacent batteries between the plurality of batteries, the spacer including at least one reflection layer that reflects at least minus 60% of an electro magnetic wave with a wavelength of 0.7pm to 3pm.

[012] The teachings in US2020406569 bring a container formed from a sheet material plate, whose folds form an octagonal prismatic structure box.

[013] As can be seen, no reference mentions a packaging system that uses octagonal straight prismatic packaging that are pressed together to form a stable set.

Description of innovation

[020] The innovation proposed here consists of a packaging system to pack electrical insulators, which are characterized by being fragile elements, generally built in friable elements such as glass or porcelain. [021] Thus, instead of the traditional rectangular boxes, built with boards fixed together, forming packages that are joined together by lashing elements, this innovation proposes a system that uses a set of packages (2) of essentially octagonal straight prismatic, as shown in Figure 2.

[022] This arrangement also allows a better use of space in containers, used to transport the baled packages (2), when compared to the traditional arrangement, with traditional square boxes. [023] Such packaging (2) consists of the association of two headboards (5), at least one intermediate support (7), four side walls (8) and at least three lashings (6). The headboards (5) are made up of octagonal-shaped planar elements with a central hole (10), whose diameter is suitable for the size of the electrical insulator to be stored. The side walls (8), in turn, are longilinear planar elements, essentially rectangular in shape, whose length is defined by the number of electrical insulators to be packed. The intermediate support (7) also presents as an octagonal-shaped planar element, while the lashings (6) are elements filaments of malleable material, such as wire, rope, polymeric tape or other material suitable for this purpose.

[024] As can be seen in Figures 2 to 5, the packaging (2) of the present innovation takes shape when side walls (8) are set orthogonally, on alternate faces, with the headboards (5), which are located at the ends of the walls sides (8). In the intermediate position of the length of the side walls (8), the intermediate support (7) is positioned, perpendicular to the side walls (8) and parallel to the headboards (5).

[025] In this configuration, the package (2) takes a prismatic shape, with a straight profile and octagonal cross-section, where its lateral external surface is formed by side wall elements (8) alternating with voids. Its top and bottom surfaces are the headboards (5).

[026] In the frame between the headboard (5) and each side wall element (8), a side reinforcement (9) is positioned, externally to the headboard (5) and internally to the side wall (8), preferably in length equal to the width of the side wall (8), allowing support between the parts when tensioning the lashing (6), which is preferably positioned on the same line as the junction of the side wall (8) with the headboard (5).

[027] Similarly, in the crimp between the intermediate support (7) and each side wall element (8), a side reinforcement (9) is positioned, preferably in length equal to the width of the side wall (8) ), joining the parts together to allow support when tensioning the lashing (6), which is preferably positioned in the same line as the junction of the side wall (8) with the intermediate support (7).

[028] Thus, the system of the present innovation uses a set of packages (2) to form a bale or group, as seen in Figure 1. This bale is preferably mounted on a pallet (1), where the packages ( two) are arranged in layers, positioning laterally to each other, so that the side walls (8) of two adjacent packages (2) coincide at their edges and, in this way, the side supports (2) of these adjacent packages (2), coincide at their edges and promote lateral locking, as seen in Figure 1A.

[029] Between each layer, intermediate bases (3) are positioned, which function as spacers, which avoid contact between the electrical insulators of the upper and lower beds, as seen in Figures IA and 1B.

[030] The packaging system is then formed by successive layers that are stacked up to the desired height, being finished by a top cover (4), which completes the set and allows the passage of fasteners, such as ribbons, ribbons or other binding elements.

[031] It is worth mentioning that the packaging (2) described here acts as a straight octagonal prism circumscribed to a "cylinder" that comprises the external faces of the set of items packaged. Specifically, as seen in Figure 6, when electrical insulators (11) are packaged, the packaging (2) prevents the insulators (11) from touching the floor or even adjacent insulators (11).

[032] This innovation is not limited to the representations discussed or illustrated here, and must be understood in its broad scope. Many modifications and other representations of the invention will come to the mind of one skilled in the art to which this innovation pertains, having the benefit of the teaching presented in the foregoing descriptions and accompanying drawings. Furthermore, it is to be understood that the invention is not limited to the specific form disclosed, and that modifications and other forms are understood to fall within the scope of the appended claims. Although specific terms are used here, they are used only in a generic and descriptive way and not for the purpose of limitation.
