Description

  The present invention relates to a structure related to a pallet, and more particularly to a plastic pallet in which a gas (A) is injected into a hollow portion (14) and a plastic injection mold having an atmospheric pressure support function can be recycled.

  In general, a pallet is a plate for cargo loading, and a forklift or handlift fork is inserted into the fork insertion port, and the cargo can be moved or transshipped by moving up and down and moving. 95% of the pallet is made of wood, and the strength of the wooden pallet is 700-3000kg load-bearing, and the material is generally low quality wood, easy to manufacture, can be mass-produced, and cheap. The present situation is that other materials or manufacturing methods cannot be replaced by wooden pallets.

However, wooden pallets have the following problems.
1. Eco problem: wooden pallets are made from wood, and the consumption of wooden pallets is increasing, and wooden pallets are used to reduce the consumption of wood as the forest area on the earth decreases. There is a search for alternatives.
2. Pathogen contamination problem: Wood that has not been processed and treated is easy to rot, parasites and pathogens are likely to be generated, and existing wooden pallets are immediately molded after wood cutting, and the surface is rough, In the process of not being treated at all, cargo is placed on wooden pallets and transported together domestically or abroad, parasites and pathogens are transported together. In addition to having a serious impact on quality, there is a risk of causing problems such as ecological destruction or infectious diseases. There are many places that require proof of "", and the cost expenditure for "smoke disinfection" increases for the traders, resulting in a problem of increased costs.
3. Structural strength problem: Each part of the wooden pallet achieves a bonded state by hitting a nail, but the bonded state is rough and lacks in stability, so there is a drawback that the bond is loosened or broken during use.

  In recent years, a paper cardboard palette has been developed, and it has become possible to use recycled paper and use it as a pallet with a structure in which a plurality of layers are bonded together. However, the moisture proofing, waterproofing effect and structural strength are insufficient, which may be inappropriate depending on the place of use or the product, and it is impossible to completely replace a wooden pallet.

In addition, there are other pallets in which wood chips or wood waste materials are compression-produced. However, since the pallets have the disadvantages and cost of the wooden pallets, it is impossible to completely replace the wooden pallets.
4). Weight problem: Wooden pallets are made of wood, so they are heavy (20-30kg), are not surface-treated, and are susceptible to moisture and other liquids, resulting in a weight of 3 minutes. As for the volume, the size of the wooden pallet is generally 120 x 100 x 20 cm. Since the volume is large, the use of the wooden pallet greatly increases the freight transportation cost. This is one of the reasons for the increase.
5). Waste issue: Wooden pallets are less valuable as wood after the cargo has been unloaded, and the possibility of being reused for furniture or wooden products is zero. At present, waste wooden pallets are paid to related organizations and burned because waste of cost and time is wasted. However, the amount of wooden pallets that are burned worldwide every year is considerable. Wasted and abandoned waste wooden pallets are piled up like a pile, causing environmental pollution problems all over the world.

  In addition, a kind of plastic pallet was developed about 20 years ago, but this kind of plastic pallet is a true plastic injection molding structure and uses a large amount of plastic material, so the price is wooden Compared to the pallet, it is four to ten times larger. In addition, regarding the load strength, the plastic material is high in strength, so the overall structure of the pallet is hard, but when an impact is applied Such plastic pallets are easy to tear and are mainly used in warehouses, but are rarely used for cargo transportation purposes, and the market penetration rate is less than 3% of wooden pallets. Its practical economic effect is not high, and it has not reached the level of replacing wooden pallets.

  Therefore, the conventional wooden pallet and plastic pallet do not solve the problem of lack of practicality when actually used. How to reduce the cost, reduce the weight, and recycle the structure. Development of pallets that can achieve the benefits of environmental protection is a development goal in the related industries.

  The inventor tackles the above issues, engages in the development and design of related products, focuses on the above goals, conducts research, makes the design more precise, repeats testing and evaluation, and finally is practical The present invention has been completed.

  An object of this invention is to provide the pallet which solved the said subject.

  The present invention includes a mounting surface (11), a landing surface (12), and an inner concave space (13) for inserting a fork of a forklift. The main feature is injection molding of the pallet (10), and the pallet. (10) is a structure having a hollow portion (14) inside, and a gas (A) is injected into the hollow portion (14), and has a pressure support function.

  The hollow part (14) of the pallet (10) may be installed locally or distributed throughout.

  The mounting surface (11) and the landing surface (12) of the pallet (10) may be integrally injection-molded, or may be separately injection-molded and combined and integrated.

The pallet according to the present invention has the following effects.
1. Improvement of eco-friendly problem: Plastic injection pallet (10) can be reused for other plastic products after disposal, and its value is higher than that of wooden pallet. Can meet protection requirements.
2. Improvement of pathogen contamination problem: The plastic injection molding pallet (10) does not have to worry about the generation of pathogenic bacteria, and can add antibacterial material during the injection molding to enhance the antibacterial effect. Can be applied to freight transportation of chemicals, etc., and at the time of import or export, it is not necessary to submit a certificate of “smoke disinfection and quarantine”, thereby saving costs.
3. Improvement of structural strength: Plastic injection-molded pallet (10) has no combination place, so the strength is stable, and it has a shock-absorbing shock-absorbing function due to the atmospheric pressure support function, thereby stabilizing the structural strength. In addition, it is not easily damaged during use.
4). Improved weight problem: The hollow structure of the plastic injection molded pallet (10) allows the plastic dosage to be reduced to 20% to 30% of the actual plastic pallet, resulting in a significant cost reduction. The cost is almost the same as that of a wooden pallet, and the weight is light compared to the weight of the wooden pallet, so that the freight cost can be greatly reduced.
5. Mass production and quality control are possible: The plastic injection pallet (10) is rapidly molded by a dedicated machine, can be mass-produced, and quality control is easy.

  Next, an embodiment of the present invention will be described.

  The features of the structure of the present invention and the effects thereof will be described below in detail with reference to examples, diagrams corresponding to the embodiments, and detailed description.
