Description

Title of the invention: Palette Technical field of the invention

[0001] The technical solution focuses on the transport pallet with blocks made of a mixture of recycled plastic and filler. State of the prior art

[0002] In the current state of the art, several embodiments of transport pallets are known. Transport pallets are most often made entirely of wood. However, wood is a relatively expensive material and, moreover, wooden pallets do not have a long service life, mainly due to the fact that wooden pallets are subject to environmental influences, especially moisture. Metal pallets are more resistant to moisture and they also have a greater load capacity. However, metal pallets also have the high weight and purchase cost. Another type of transport pallets represent paper pallets. These pallets are known above all for their low weight. But paper pallets also have a low load capacity and degrade in the same way as wooden pallets due to moisture.Another alternative to wooden pallets are plastic pallets, which are moisture-resistant and weigh less than metal pallets. However, these pallets are completely disposed of when damaged; it is not possible to replace, for example, only the damaged part, as is possible with a wooden pallet. Therefore, they are harmful to the environment.

[0003] Sorting rejects from plastic waste sorting are plastic waste consisting mainly of various polymer materials and a large amount of impurities. This includes the residual component of the contents of plastic sorting containers that cannot be processed during standard recycling. Thus, sorting rejects are often incinerated or landfilled without being recovered. Nowadays, efforts are being made to recover this waste as well. The processing of sorting rejects from plastic waste sorting for further recovery is published in utility model CZ35922U1 (Device for processing sorting rejects from plastic waste sorting). However, this document does not describe the concrete possibilities for using the processed sorting rejects.

[0004] It would be appropriate to find a solution for a pallet that would have a longer lifespan, a higher load capacity with the least negative impact on the environment and the lowest possible production costs. Essence of the technical solution

[0005] The above-mentioned disadvantages are to some extent overcome by a pallet which comprises an upper part defining the load-bearing surface, a lower part and at least four blocks which connect the upper part and the lower part. Each block consists of a mixture comprising recycled plastic and a filler selected from the group consisting of automotive glass, sand and / or ash. Preferably, the ash may come from the plastic waste incinerator. The recycled plastic may come from the sorting rejects resulting from the sorting of plastic waste already treated for further use. Advantageously, the plastic sorting rejects may be contained in the block in a greater quantity than the filler, for example automotive glass. Advantageously, the proportion of recycled plastic in the block may be between 50 and 90% and that of filler between 5 and 50%.The mixture may optionally include other components, for example binders, etc.

[0006] Thus, for the blocks of the pallet waste is used that might no longer find application elsewhere, which can reduce the negative impact on the environment and reduce the purchase costs of the pallet. The addition of crushed automotive glass to the recycled plastic from plastic sorting rejects increases the load capacity of the blocks and the pallet. Thus, the load capacity of the pallet according to this solution can be higher than the load capacity of, for example, a pallet made entirely of wood with blocks of the same dimensions. Based on the higher strength of the pallet according to this solution, the service life of the pallet can also be longer, preferably by 20 to 30%, than the service life of a pallet made entirely of wood. At the same time, this mixture reduces the weight of the entire pallet, because the blocks made from this mixture have a lower weight than blocks of the same dimensions made of wood or metal.

[0007] The upper part may have an outer contour, according to the plan view, in the shape of a rectangle, which is a standard shape for transport pallets. Advantageously, a block may be located in each corner of the upper part. Thus, a more stable position of the pallet can be ensured.

[0008] Advantageously, the blocks may be arranged in triplets in the pallet such that two blocks of each triplet of blocks are located on opposite edges of the upper part and the third block of each triplet is located between two blocks of the same triplet. Thanks to this arrangement, it is possible to ensure an increase in the stability of the pallet, in particular in the central part of the pallet which can be damaged more often, and at the same time, sufficient space is provided for the introduction of the forks of a forklift to handle the pallet. The block located on the edge of the upper part may be offset from said edge, preferably by a distance less than or equal to the dimension of the block measured in the direction of the offset.

[0009] The upper part may comprise at least three longitudinally oriented boards, preferably at least five, and at least two transversely oriented boards connecting the longitudinally oriented boards. The longitudinal direction may be defined as the direction of loading the pallet onto the forks of the forklift. The transverse direction and the longitudinal direction may be interchangeable.

[0010] Advantageously, the lower part comprises at least two boards, each board being fixed to at least two blocks.

[0011] Advantageously, each block comprises a greater proportion of recycled plastic than filler.

[0012] Advantageously, the blocks can be attached to the upper part and the lower part in a removably manner, so that, for example in the case of damage to a block of the pallet, only the damaged block can be replaced and it is not necessary to dispose of the entire pallet. This leads to a reduction in the negative impact on the environment.

[0013] The upper part and the lower part may be made of wood. Advantageously, it is possible to replace only the wooden blocks with blocks made of a mixture comprising recycled plastic and a filler, for example automotive glass, which are more resistant. Description of the figures

[0014] The essence of the technical solution is set out below with the help of examples of its implementation which are described with reference to the attached drawings, in which:

[0015] [Fig-1] represents an isometric view of a pallet with the upper part visible, and

[0016] [Fig.2] represents an isometric view of a pallet with the lower part visible. Examples of implementation of the technical solution

[0017] The technical solution will be explained in more detail with the help of the embodiment examples with reference to the respective drawings. An embodiment example of the pallet is shown in [Fig.l] and [Fig.2].

[0018] The pallet comprises an upper part 1 and a lower part 2 which are connected by several blocks 3.

[0019] The upper part 1 is intended for loading the load. The upper part 1 may comprise several longitudinal boards and several transverse boards, as shown for example in [Fig.l]. Here, the boards are arranged so that the outer shape of the upper part 1 is rectangular, according to the plan view. Alternatively, the shape of the upper part 1 (possibly also of the lower part 2) may be square, according to the plan view. Advantageously, the boards, for example the longitudinal boards, may be arranged in the same plane (preferably horizontal) with such spacings that it is possible to put a load on the upper part 1. In the embodiment example of [Fig.l], three boards are arranged transversely - two end boards and the third between them, preferably in the middle. More boards may be placed in the longitudinal direction than in the transverse direction, for example seven, as shown in [Fig.l].The longitudinal direction can be defined, for example, by the direction of insertion of the pallet onto the forks of the forklift, or for example, for a pallet with a rectangular plan, the longitudinal direction can be defined by the edge of one of the longer sides of the rectangle. The longitudinal boards on which the load can be loaded are, in the embodiment shown in [Fig.l], placed on the transverse boards, which are in direct contact with the blocks 3. Alternatively, the transverse boards can be replaced by longitudinal boards or the longitudinal direction by the transverse direction. In another embodiment, the boards in the longitudinal direction can be in direct contact with the blocks 3, and on them can be placed transverse boards which can be more numerous than the longitudinal boards.Advantageously, the longitudinal boards can be fixed to the transverse boards using nails, so that, for example, in the event of damage to a board, only that damaged board can be replaced. Alternatively, the boards can be connected by gluing, for example. Alternatively, the upper part 1 can consist of a tray.

[0020] Blocks 3 connect the upper part 1 and the lower part 2 and their dimensions define the distance between these parts. When manufacturing the blocks 3 waste is used, which helps to reduce the negative impact on the environment, unlike for example blocks 3 or pallets made entirely of non-recycled plastic. A mixture is used comprising recycled plastic from sorting rejects from the sorting of plastic waste, which has already been freed from impurities and further processed (e.g. melted), and filler, which can be crushed automotive glass and can increase the strength and cohesion of the entire block 3, thus extending the service life of the pallet. In addition to crushed automotive glass, the filler can also be sand or ash from the plastic waste incinerator.Sand or ash can completely replace automotive glass in block 3, optionally the material of block 3 may include glass. crushed automobile with sand and ash. Each block 3 may consist of a mixture comprising recycled plastic and filler comprising automotive glass, sand, ash or a combination thereof. Plastic sorting rejects and automotive glass are materials that are difficult to recycle. The pallet thus uses materials that, for example, could no longer be used otherwise. Advantageously, block 3 may comprise

[0021] 85% recycled plastic and 15% crushed automotive glass. Blocks 3 can have the shape of a rectangular parallelepiped, as shown for example in [Fig.l]. The total dimensions of block 3 may advantageously depend on the dimensions of the pallet, the required load capacity of the pallet, etc.

[0022] The number of blocks 3 may depend on the design of the upper part 1 and the lower part 2, in particular on their dimensions. To ensure the stability of the pallet, it is appropriate to provide at least four blocks 3 per pallet, which may advantageously be located, for example, in the corners of the upper part 1. For a rectangular upper part 1, where the longitudinal dimension is longer than the transverse dimension, the pallet may have three pairs of blocks 3. Two pairs of blocks 3 may be located in the corners of the upper part 1 and one pair may be located between the four end blocks 3, one opposite the other at the edges of the upper part 1, for example in the center of the longer sides of the upper part 1.To reinforce the central part of the pallet, especially for larger pallets (e.g. for pallets with dimensions 1180x1000 mm), it may be advantageous to arrange the blocks 3 in triplets and particularly in at least two triplets. This is shown for example in [Fig.l], where two blocks 3 of the triplet are located at the edges of the upper part 1 and the third block 3 of the triplet is located between them, advantageously so that, for example, when viewed from the side of the pallet (perpendicular to the longest side of the upper part 1), the blocks 3 of the triplet are aligned. Similarly, the blocks 3 can also be arranged in the longitudinal direction in such a way that the individual blocks 3 are aligned with the other blocks 3 according to the front view.

[0023] The lower part 2 may comprise, for example, only longitudinally oriented boards, as seen in [Fig. 2]. Here, each board is fixed to three blocks 3 in the longitudinal direction, two boards are located on opposite edges of the pallet and one board is fixed in the middle of the pallet. The boards of the lower part 2 are not connected to each other here. This arrangement ensures sufficient load support (especially in the central part which can often be damaged) and at the same time ensures sufficient space for the forks of the forklift to handle the pallet. Alternatively, the lower part 2 may have a similar construction to that of the upper part 1 - boards longitudinal and transverse boards, or for example, the lower part 2 can be made of a tray.

[0024] Advantageously, the blocks 3 can be fixed to the upper part 1 and to the lower part 2 using nails, so that the blocks 3 can be separated from the remaining parts of the pallet. In the event of damage to a block 3 of the pallet, this block 3 can be removed and replaced by a new block 3. Alternatively, the block 3 can be fixed to the upper part 1 and / or to the lower part 2 by gluing, for example.

[0025] The upper part 1 and the lower part 2 may be made of wood. Advantageously, both the upper part 1 and the lower part 2 may thus comprise longitudinal boards and / or transverse boards made of wood. For example, for damaged blocks 3 in a pallet made entirely of wood, the wooden blocks may be replaced by the blocks 3 made from a mixture of recycled plastic and filler. List of landmarks
