Description

DESCRIPTION

plastic pallet

Object of the invention

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

Background of the invention

Pallets are known for the hauling of goods, which are platforms with lower holes for the passage of the claws of a pallet truck or stacking bull for said pallets. This facilitates the handling of stacks of merchandise arranged on the pallet, by means of 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 rotting as they are organic material, 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 the focus of pests that require their phytosanitary treatment; as well as regularly accumulate moisture 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 one-piece piece of plastic provided with a load cover with ribs, and also provided with legs between which there are certain holes for the passage of the nails of the pallet truck or pallet stacking bull.

In some variants of plastic pallets, between some or all of the legs there are lower ribs, which brace the pallet at the bottom and prevent it from deforming. Similarly, in some variants of pallets, the load deck comprises 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 by 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 area of the pallet loading deck may be different from that of the stacks of merchandise arranged in tiers thereon. These stacks comprise levels between which are interspersed laminar separators -preferably plastic- that have the same plan dimensions as the stacks, the stack usually being consolidated by means of a common shrink-wrapped cover. When there is a difference in plan dimensions between the platform or pallet loading deck and the stack, either space is wasted, or the stacks -and therefore the separators- are exposed to knocks and scratches, which often makes their reuse impossible. , being precisely the reuse of these plastic separators 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 inconvenience due to the large number of separators that are moved, 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 piece of plastic provided with a load 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 stacking bull, some or all of said legs comprising some lower ribs, and the load deck comprising a perimeter wing. Therein, according to the invention:

-the cargo deck 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 comprises cornered centering pivots, corresponding to corner 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, adapts to the production lines of the glass and the packers, and the adaptation of the separator to the pallet is improved, giving the whole safety and robustness as a packaging unit.

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 one-piece piece of plastic provided with a cargo cover (2) with ribs (20), and provided with legs (3) among which there are certain holes (4) for the passage of the nails of a pallet truck or pallet stacking bull, comprising some or all of said legs (3) some lower ribs (5) (see also fig. 3 and 4); the cargo deck (2) comprising a perimeter wing (21). Therein, according to the invention:

-the loading deck (2) has plan dimensions equal to those of a plastic laminar separator (100) of levels in stacks of goods, and

- the upper face of the cargo cover (2) comprises some corner centering pivots (22), corresponding to some corner notches (101) of the spacer (100).

Specifically, it is preferred that the loading deck (2) has plan dimensions of 1 x 1.20 metres, which is a standardized measurement widely used in laminar separators in the glass and packaging sector.

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

Additionally, the lower ribs (5) can be blind or have perforations (see fig. 4), which allows for a kind of drainage and prevents water from accumulating. There may be lower ribs (5) in transverse directions, for example in the entire 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 every three legs , in the same direction, variant not represented.

In addition, in this preferred embodiment, the cargo cover (2) comprises, in the areas arranged between the legs, reinforcements selected from solid plastic (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 a reinforcement in these areas of main support against the forks of the pallet truck, which improves its resistance against friction, knocks from the forks of the pallet truck and against deformations.

In addition, it has been provided (see figs. 2 and 3) that the upper face of the load surface (2) may include portions of non-slip material (6). This cooperates with the corner centering pivots (22) in keeping the stack perfectly centered with the pallet and its sides aligned, even in the movements of moving and carrying the pallet. Ideally, the cargo cover (2) will include sockets (27) for the non-slip material portions (6), so that they can be removed or replaced in the event of damage. Similarly, additional portions of sliding material, not shown, can be arranged on the underside of the loading deck (2) in contact with the forks of the pallet truck to improve grip with said forks of the pallet truck, and also on the lower part of legs (3) and/or lower ribs (5), to improve stability in stacks or shelves, also inserted in the corresponding sockets.

It is preferred that the fillets between the legs (3) and the underside of the cargo deck (2) are rounded, as this increases structural strength.

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 transport, distribution and storage process in 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) fittable in the entrance opening to the housing (30). This keeps the circuit holder (32) in its position preventing it from coming out, and allows the RFID circuit (31) to be exchanged in case of damage.

Notwithstanding the foregoing, and since the description made corresponds only to 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 manufacturing materials of the assembly or its parts, without implying any alteration of the invention as a whole, limited only by the claims which are provided below.
