Description

PLASTIC PALLET

DESCRIPTION

Object of the Invention

The present invention refers to a plastic pallet, usable for the transportation of goods arranged in stacks with levels separated by plastic or cardboard laminar separators, especially intended for the transport and distribution of hollow glass containers intended for the food and beverage sector. .

Background of the invention

For the transportation of goods, pallets are known, which are platforms with lower holes for the passage of the nails of a pallet truck or stacker bull for said pallets. This facilitates the handling of stacks of merchandise arranged on the pallet, using said pallet trucks or bulls.

Traditionally, pallets are made of pine wood, due to its easy availability and cost savings. However, they have other types of problems, such as the appearance of rot as they are organic materials, which can weaken their own structure, apart from being a source of unhealthiness when it comes to edible or sanitary goods. Additionally, wooden pallets can be a source of pests that require phytosanitary treatment; as well as regularly accumulate humidity that affects their structure and weight.

To avoid this, pallets made of plastic materials are also known, and very typically made of recycled plastics. They are materialized in a monobioque piece of plastic provided with a loading cover with ribs, and also provided with legs between which there are certain gaps for the passage of the nails of the pallet truck or pallet stacker bull.

In some variants of plastic pallets, between some or all of the legs there are lower ribs, which internally brace the pallet and prevent it from deforming. Likewise, in some pallet variants, the loading cover includes a perimeter wing that increases its surface area compared to that of a standard pallet.

The use of plastic pallets has the advantages that it is a reusable element that improves the Carbon Footprint and reduces deforestation, cross contamination from remaining wood and chips is eliminated, it does not absorb moisture compared to the wooden pallet, and it has greater durability and number of uses (from an average of 7-10 in wood) to more than 100 in plastic. However, the surface of the pallet's loading deck may be different from that of the stacks of merchandise arranged in levels on it. These stacks comprise levels between which are inserted lamellar separators - preferably made of plastic - that have the same dimensions in plan as the stacks, the stack usually being consolidated by a common re-actylated cover. When there is a difference in dimensions in plan between the platform or loading deck of the pallet and the stack, either space is wasted, or the stacks - and therefore the separators - are exposed to knocks and scratches, which frequently makes their reuse impossible. , the reuse of these plastic separators being precisely an industrial business where a large number of separators are moved, which are recovered, cleaned, repaired where appropriate, and dispensed again. Therefore, the breakage of separators is a costly problem due to the large number of separators that move, especially in the food industry.

Description of the invention The plastic pallet of the invention is of the type that is materialized in a monobloc plastic piece provided with a loading cover with ribs, and provided with legs between which there are certain holes for the passage of the nails of a pallet truck or pallet stacker, between some or all of said legs comprising lower ribs, and the loading cover comprising a perimeter wing. Therein, according to the invention.

-the cargo cover has plan dimensions equal to those of a plastic laminar separator of levels in stacks of goods, and

-the upper face of the cargo cover includes cornered centering pivots, corresponding to cornered notches of the plastic separator. In this way, a perfect centering of the stack with respect to the pallet is achieved, which, having the same dimensions as the separators, protects them and minimizes damage, with maximum use of space, adapting to the production lines of the glass and manufacturing sector. the packagers, and the adaptation of the separator to the pallet is improved, giving the whole security and robustness as a packaging unit.

Figures 5 and 6.- They respectively show a view of a housing for a passive RFID circuit with a circuit holder partially inserted, and the circuit holder removed with the RFID circuit. Description of the Preferred Embodiment

Starting with figs. 1 and 2, it can be seen that the plastic pallet (1) of the invention is of the type that is materialized in a monobloc plastic piece provided with a loading cover (2) with ribs (20), and provided with legs (3) among which there are certain gaps (4) for the passage of the nails of a pallet rack or pallet stacker, comprising between some or all of said legs (3) some lower ribs (5) (see also fig. . 3 and 4); the cargo cover (2) comprising a perimeter wing (21). Therein, according to the invention:

-the cargo cover (2) has plan dimensions equal to those of a separator (100) laminate plastic tiers into stacks of goods, and

• the upper face of the cargo cover (2) comprises cornered centering pivots (22). corresponding with corner notches (101) of the separator (100). Specifically, it is preferred that the loading deck (2) has plan dimensions of 1 x 1.20 meters, which is a standardized measurement widely used in lamellar separators in the glass and packaging sector.

Likewise, it is preferred that the total height of the pallet (1) is 155 millimeters, and the perimeter wing (21) of the loading surface (2) has a height of 37 millimeters, perfectly adapted to the dimensions of the wooden pallet model. ANIFE used by the glass sector and glass packers in the food and beverage sectors.

Additionally, the lower ribs (5) can be blind or include perforations (see fig. 4), which allows for a type of drainage and prevents water from accumulating. There may be lower ribs (5) in transverse directions, for example throughout the perimeter defined by the legs (3) and between the central leg with two aligned legs, as seen in figure 4, or only parallel ribs between each three legs. , in the same direction, variant not shown.

Furthermore, in this preferred embodiment, the cargo cover (2) comprises, in the areas arranged between the legs, reinforcements selected from plastic solids (25) and/or nearby ribs (26) - that is, with less separation between the same as in the rest of the cargo deck (2) -. This offers reinforcement in these main support areas against the nails of the pallet truck, which improves its resistance against friction, impacts from the nails of the pallet truck and against deformations.

Additionally, it has been planned (see figs. 2 and 3) that the upper face of the loading surface (2) may comprise portions of non-slip material (6). This cooperates with the cornered centering pivots (22) in keeping the stack perfectly centered with the pallet and its sides aligned, even during the movements of transferring and carrying the pallet. Ideally, the cargo cover (2) will include fittings (27) for the portions of non-slip material (6), so that they can be removable or replaced in case of deterioration. Similarly, on the underside of the charging cover (2) in contact with the nails of the pallet truck you can arrange portions of matter! additional sliding, not shown, to improve the grip with said nails of the pallet truck and also in the lower part of the legs (3) and/or lower ribs (5), to improve stability in stacks or shelves, also inserted in the corresponding lace

It is preferred that the connections between the legs (3) and the lower face of the cargo cover (2) be rounded, since this increases the structural resistance.

Finally, the pallet (1) includes a housing (30) for a passive RFID circuit (31), which allows signaling and traceability of each unit, controlling its presence in the different phases of the transportation, distribution and storage process. the window and packaging facilities, which represents a substantial improvement in relation to wooden or plastic pallets that usually do not incorporate it. In said housing (30) a circuit holder (32) is inserted, with a base (32a) fitting into the entrance opening to the housing (30). This keeps the circuit holder (32) in its position, preventing it from coming out, and allows the exchange of the RFID circuit (31) in case of deterioration.

Notwithstanding the foregoing, and since the description made corresponds only to an example of a preferred embodiment of the invention, it will be understood that within its essentiality multiple variations of detail may be introduced, also protected, which may affect the shape, size or the manufacturing materials of the assembly or its parts, without this implying any alteration of the invention as a whole, limited only by the claims provided below.
