Description

DESCRIPTION

Load stacking system

field of invention

The present invention refers to a load stacking system, which has application in the logistics industry, and more specifically in the field of packaging for the transport and storage of preferably heavy slab-type, large-format and/or fragile loads. on pallets, allowing them to be protected adequately and quickly, as well as the stacking of several pallets without the weight of said stacking having to be supported by the load itself and said weight being distributed at different points of the system.

Background of the invention

For example, in the ceramic sector, systems are known for transporting loads formed by stacking large slabs on a pallet that consist of placing two wooden goals on opposite sides of the load, which are formed by four pillars of wood joined by horizontal or cross crossbars, and sometimes these goals are also joined together by a horizontal connecting crossbar, all subject to the load using film.

A drawback of these known systems is that creating this protection is slow to assemble, heavy and expensive from an economic point of view, both due to the need for operators to assemble it and the impossibility of reusing the elements of the goal.

On the other hand, this wooden solution takes up a lot of space for its own storage until use. In addition, wood normally requires phytosanitary treatments for export.

The holder of this application designed the corner guard for stacking loads described in the utility model ES1291463U which, among other aspects, enables the protection of the vertical edges and corners of a load arranged on a pallet with the purpose of protecting it against bumps or scratches in these areas with external elements during handling or transportation.

The system described in this invention allows a load of preferably slab-type format located on a pallet to be quickly and reliably protected, with pillars located on the sides of the pallet, versatile and having sufficient resistance to stack several pallets without the weight itself of the pallets arranged in higher positions affects the loads located on those pallets arranged in positions lower than the previous ones, comprising a plurality of contact elements that define a plane of contact with a lateral face of the load and rest on said lateral face.

The integral parts of said pillars are located externally with respect to the parts that make up the load itself to avoid interference that could damage it during stacking.

Description of the invention

An objective of the present invention is to provide a load stacking system that provides a series of advantages over systems that use corner pieces such as those mentioned above or even materialized with other geometric variants, allowing the weight of the stacking of several pallets not to fall on exclusively on the vertical edges and corners of a load, but rather it is distributed and supported with other areas of the stacking system, providing it with greater security.

Additionally, it allows the stacking of a greater number of pallets with their respective loads in the distributor's warehouses, optimizing the space of their facilities.

The load stacking system according to the present invention is described in claim 1, and the dependent claims include additional features that are optional.

In particular, the load stacking system includes:

A pallet that defines corners and is provided with a plurality of lower support blocks, and pillars located on the sides of the pallet in correspondence with the aforementioned pallet blocks.

The pillars comprise a main body capable of being located on the sides of the load and where said main body comprises a plurality of contact elements that define a plane of contact with a lateral face of the load and rest on said sides unlike the corners described in ES1291463U which, on the contrary, are enabled so that the corners or edges of the load are introduced into its hollow interior, such that they embrace and house them in said interior part.

According to a preferred embodiment, each pillar defines a vertical main body with a suitable cross section so that the compression does not collapse. Preferably said section is V-shaped, although it could be U, H, etc.

The main body is finished off top and bottom by respective horizontal partitions, that is, perpendicular to the main body.

The possibility is contemplated that said partitions form a single-piece body with the main body or even that they comprise assembly or coupling means between them.

Preferably, said partitions emerge transversely to the main body of the pillar and face outwards with respect to a vertical projection plane of the load.

Thus, any part or element included in the pillars themselves, that is, both the main body, the horizontal partitions, and the lateral wing mentioned later, are located externally with respect to the parts that make up the load itself to avoid interference that could damage it during stacking.

These horizontal partitions provide greater resistance to the pillar and allow the weight of the stacking of pallets to be distributed more effectively towards the main body of the pillar. Both partitions work in compression together with the main body.

Advantageously, each pillar together with the upper and lower horizontal partitions is symmetrical with respect to at least one transverse axis. Preferably it will be with respect to a horizontal axis and a vertical axis, which allows not only the arrangement of each of them on both the larger sides (long side) and the smaller sides (short side) of the load and the pallet itself. correspondence with the corners of these and even in intermediate positions of the aforementioned major and/or minor sides as will be seen later.

Each pillar may internally comprise at least one transverse reinforcement brace adapted to cooperate in the transmission of the mechanical load to the main body of the pillar during stacking and so that the main body of the pillar does not collapse under a vertical load, serving as a connecting link between both ends of the main body of the pillar.

Each pillar may internally comprise a plurality of horizontal reinforcing ribs and at least one vertical rib to mechanically strengthen the main body.

The possibility is also contemplated that at least one of the pillars when they are located at the corners of the pallet comprises at least one lateral wing that extends with respect to the main body (22) of the pillar (3) and that is perpendicular to the defined plane. by the plurality of contact elements that define the plane of contact with a lateral face of the load.

Said at least one lateral wing can extend along the height of the main body (22) of the pillar (3).

In this way, while the plurality of contact elements contact and rest on one side of the load, the at least one wing does the same on the side of the load adjacent to the previous one.

The possibility is contemplated that for contact and support of the at least one lateral wing with a side of the load, said wing comprises a flat face or even a plurality of transverse ribs.

In this case, each pillar, together with the upper and lower horizontal partitions and with at least one lateral wing, is symmetrical only with respect to a transverse axis. Preferably it will be with respect to a horizontal axis, such that this pillar configuration even allows the use of a pillar in any corner of the system by carrying out the simple maneuvers of turning, turning or combining these.

Preferably, the upper and lower horizontal partitions of each pillar comprise a plurality of pointed-shaped projections distributed on their surface, suitable for facilitating their interlocking in the structure of the pallet and trying to avoid or hinder unwanted movements during stacking and transportation.

The system may comprise means for fixing the pillars to the pallet blocks. Preferably, these means are arranged in the pillars located in the intermediate positions mentioned below and in correspondence with the partitions. The possibility is contemplated that the partitions include holes adapted to house respective lag bolts for preferable fixation by screwing the partitions to the pallet depending on the orientation given to the pillar during installation.

Advantageously, the upper and lower horizontal partitions of each pillar can comprise at least two inclined ribs to reinforce the partitions themselves with the main body.

Furthermore, the stacking system contemplates the possibility of comprising at least two pillars arranged in intermediate and opposite positions either on the larger or smaller sides of the pallet that can be joined by a beam that extends transversely over the load and that preferably comprises two zones. widened for the support and connection of the stringer with the upper horizontal partitions of both pillars.

The stringer comprises at least one hole with a lock in which a lag screw is housed for joining the stringer with a pillar, and the lock may comprise a toothing complementary to a toothing of the hole to allow adjustment in width.

The pillar-load assembly can be adequately packaged, by strapping, shrink-wrapping or a mixture of both to form a compact assembly.

Description of a preferred embodiment

Figures 1a and 1b show perspective views of the load stacking system applied to a pallet according to two embodiments.

In these figures it can be seen that a load (1), for example, of large format, such as of the order of 120x120 cm, 75x150 cm or 80x160 cm.

The load stacking system according to the present invention comprises a pallet (2) and pillars (3), such that the dimensions of the pallet (2) correspond to the sum of the maximum dimensions of the load (1), the thickness of the pillars (3) and a small margin for safety of the positioning of the load (1) on the pallet (2).

Preferably the pillars (3) are one-piece, made of plastic material and with a hollow interior.

In the embodiment of Figure 1a, said pillars (3) are located only in the corners of the pallet (2), while in the embodiment of Figure 1b it additionally incorporates pillars (3) located in intermediate positions between the corners of the pallet ( 2).

In addition, the load stacking system according to the present invention can also comprise a beam (4) that extends transversely over the load (1) without establishing contact with it and that joins together two pillars (3) located on the sides. opposites of the load. Said stringer (4) preferably comprises widened areas (19) at its ends, to facilitate the joining of the stringer (4) to the pillars (3), as will be explained with reference to Figures 5 and 6.

In the embodiment examples of Figures 7a and 7b, stacking systems for various loads (1) are shown respectively, incorporating and without incorporating the stringers (4) in their intermediate sections.

The pallet (2) of the load stacking system according to the present invention comprises blocks (5), corresponding to the position of the pillars (3).

Figures 2a and 2b show possible embodiments of a pillar (3) that are used in the load stacking system (1) according to the present invention. As can be seen in said figures, the pillar (3) comprises an elongated main body (22), which preferably has a V-shaped cross section, which could have other cross-sectional sections such as U-shaped, H-shaped, etc. , and partitions (6, 7) located at both ends of the main body (22), which are preferably equal to each other and define a larger area than the rest of the pillar (3). In their position of use, represented in Figures 1a and 1b, the partitions can be defined as an upper partition (6) and as a lower partition (7).

In the embodiments shown in these figures, it is also observed that the main body (22) comprises a plurality of contact elements (23) that define a plane of contact with a lateral face of the load (1), such that said plane is capable of contacting and supporting said side.

Furthermore, the pillar (3) is preferably hollow and internally comprises a plurality of longitudinal reinforcement ribs (8) and a transverse reinforcement tie (9), in this case horizontal, to mechanically strengthen the main body and as seen in the Figures 1a, 1b, 7a and 7b, the edges or corners of the load (1) are never introduced into the hollow interior of the pillars (3), but rather rest on said plurality of contact elements (23).

The partitions (6, 7) emerge transversely to the main body of the pillar (3) and face outwards with respect to a vertical projection plane of the load (1). In this way, as seen in Figures 1a, 1b, 7a and 7b, any part or element included in the pillars themselves (3) is located externally with respect to the parts that make up the load itself (1) to try to avoid or minimize interference that could damage it during stacking.

In these embodiment examples with the V-shaped main body, this transverse reinforcement brace (9) helps prevent the pillar (3) from collapsing under a vertical load, since it serves as a connection between the two parts of the main body ( 22) of the V-shaped pillar (3).

With this type of pillar (3) greater resistance is achieved and the weight of the stacking of the pallets (2) is distributed more effectively towards the main body (22) of the pillar (3), such that both partitions (6, 7 ) work in compression together with the main body (22).

Furthermore, as the pillar (3) of the example embodiment of Figure 2b is symmetrical with respect to a horizontal axis and a vertical axis, it can be used both in opposite corners at the time of assembly with the load (1) and the pallet (2). ), as well as in intermediate sections on the sides of the load itself (1).

On the other hand, Figure 2a shows an example of an embodiment for the case in which the pillar (3) is intended exclusively to be located in confluence with one of the corners of the load (1), said pillar (3) can optionally comprising at least one lateral wing (18) that extends with respect to the main body (22) of the pillar (3) and is perpendicular to the plane defined by the plurality of contact elements (23) that define the plane of contact with a face load side (1).

In the example embodiment of Figure 2a, a single lateral wing (18) is observed that extends along the height of the main body (22) of the pillar (3).

Said lateral wing (18) comprises, in turn, a face with a plurality of transverse ribs (9') also capable of contacting and supporting a side of the load (1).

In this way, while the plurality of contact elements (23) contact and rest on one side of the load (1), the transverse ribs (9') of the face of the wing (18) do the same on the side of the load (1) adjacent to the previous one.

The pillars (3) with wings (18) are used to be placed in correspondence with the corners of the pallet (2), while the pillars (3) without wings are preferably used in intermediate areas of the pallet (2).

It should be noted that the pillar (3) shown in fig. 2a, is symmetrical in this case, with respect to a horizontal axis and has the peculiarity of being reversible, that is, it can be mounted both in the left and right corner simply by simply performing the operations of turning, turning or combining these. In this way, the wing (18) and the main body of the pillar (3) contain the displacements of the load in two directions perpendicular to each other.

Furthermore, in Figure 3 it can be seen that the partition (6) comprises a plurality of projections (10), which serve to facilitate the locking of the pillars (3) in the pallet (2).

The partitions (6, 7) of the pillar (3) also comprise a plurality of reinforcing ribs (11) that cross each other, as shown in Figure 3.

In addition, the partitions (6, 7) of the pillar (3) include means for fixing the dowels (5) of the pallet, in these embodiments being holes (12, 13) for the passage of screws (14, 15). ), shown in figures 3, 4, 5 and 6, to fix both the pillar (3) to a block (5) of the pallet and to fix the beam (4) to the pillar (3), preferably by screwing.

As shown in Figures 5 and 6, according to the embodiment represented, the widened areas (19) of the stringer (4) rest on the upper partitions (6) of the pillars (3) and serve as a connection between the stringer ( 4) and two pillars (3) located on opposite sides of the load (1).

For the aforementioned stringer-pillar connection, a bolt (16) is used that is housed in a hole (21) of the stringer (4), a lag bolt (15) being inserted into said bolt (16). This bolt (16) comprises a toothing (17), which is complementary to a toothing (20) of the hole (21).

This bolt (16) allows an approximate adjustment of ±5 mm in width thanks to the serrations (17, 20) of the bolt (16) and the stringer (4).

It should be noted that the upper support plane defined by the pillars (3) must be the same in all cases, so, if a beam (4) is used, the pillar (3) without a wing must be a model immediately lower in height than the pillars (3) with wing (18) and, if it does not have a stringer, all the pillars (3) with and without wing are of the same height.
