Description

Detailed Description of the Invention

  The present invention is mainly intended to reduce the weight of pallets used for transporting and storing cargo, to improve workability, and to reduce the total volume of piles when not in use (storage). (Legs) are manufactured separately, the pallet is easy to assemble and disassemble when storing, and the struts are "nested" so that they do not slip or collapse due to stacking during storage. It not only reduces the total volume of the time but also prevents accidents due to the above-mentioned lateral displacement and collapse.

  Conventionally used pallets are mainly made of wood and consist of top and bottom plates and struts connecting them, most of which are assembled using metal nails, and the pallet's own weight However, it is difficult to change the shape and reuse the used wood. Moving the pallet during storage, especially storage by stacking, has the risk of lateral displacement and collapse, and improvements are required. .

Problems to be solved by the invention

  Conventionally used wooden pallets are thick in order to maintain strength, and therefore their own weight is heavy, workability is poor, and weight reduction is desired. In addition, the volume accumulated for storage during storage cannot be reduced structurally, and cannot be less than (volume of one unit) x (number of units). In the present situation, the space is piled up high and the space is narrowed accordingly, and there is a risk of collapse in particular, so improvement is desired.

  In addition, when used for export packaging, wooden operations require sterilization such as fumigation as required by law, and pallets that have been assembled or previously assembled with components that have been previously sterilized or the like There is a hassle that must be used. This also affects the distribution cost of the cargo to be transported, which naturally increases.

  In addition, wooden pallets have disadvantages that change in the contents related to the basics of transported goods, such as when the weight changes due to moisture absorption in places such as outdoors or in humid places. It is necessary to eliminate these events. Yes.

Means for solving the problem

The pallet of the present invention uses only plastics as its material, or uses wood, bamboo or their chips, sawdust, carbonized wood / bamboo, glass fiber, iron wire, etc. as an aggregate or extender. As a result, the pallet can be strengthened, reduced in weight and reduced in price.
In addition, the pillars are made into a spindle shape and “nested” to minimize the volume when storing the pallets by stacking them, and they can be stacked as high as they can. Can prevent accidents caused by this, and can prevent accidents such as sterilization by fumigation during export, and there is no change in weight caused by sucking moisture. Higher distribution costs can be eliminated.

  An embodiment of the present invention will be described with reference to the drawings. The main material used in the present invention is 200 ° C. mixed with plastics or waste plastics with an aggregate for maintaining and reinforcing the strength described in the paragraph “0006” or an extender with an allowable range that does not affect the strength. Either a flat plate formed by a method such as heat extrusion before and after, or a spider base plate further processed, a flat plate introduced with a honey-cam structure (all these are simply referred to as flat plates) and a polygonal pyramid including a cone It was configured as a support (hereinafter simply referred to as a support). Here, a description will be given with reference to an example in which a conical shape is adopted as a support.

  FIG. 2 b is a cross-sectional view of a support column that is hollow-molded using waste plastics. Accordingly, the portion corresponding to (2) in FIG. 2b corresponds to the thickness of the flat plate, and (3) should serve as a stopper for preventing the column from coming out by contacting the back side of the flat plate. .

  In order for (4) to come into contact with the front side of the flat plate, it remains to be cut at equal intervals in the three directions of the pillar circumference, and functions as a stopper to prevent it from falling down, which functions by folding each of them outward. As shown in FIGS. However, since the column and the column are originally integral and the bent portion (6) is a curved line, a crease is produced when it is bent. Therefore, the bulge caused by the crease is absorbed by the notch (5) shown in FIG. In addition, the bulge that occurs when the width of the portion of the heel that is left in the three directions at regular intervals and that touches the struts is narrowed by the notch (5) and the heel is bent outwards is reduced, but is not completely eliminated. . However, the bulge increases the pressure (amount of friction) against the inner wall of the hole into which the column is fitted and prevents it from falling off the column. I did not.

  At the expense of being able to disassemble the column and the flat plate, even if the heel is glued with adhesive etc. in the same way as in (3) in the three directions so as to adapt to the curve of the column from the beginning, The function to prevent falling off can be performed. However, in consideration of the fact that the support may interfere with transportation and work depending on the application, it is difficult to sacrifice the mechanism that can be disassembled.

  Also, if the column is a polygon, the outer periphery will be the same number of continuous straight lines as the number of polygonal pyramids, so if the appropriate number of sides is bent outward at the appropriate position, it will not fall off and can be prevented from falling out. Can be added.

  In any case, the most important part of the present invention is the column part, which is characteristic and symbolic in that the column is made into a weight type and "nested", and the column can be freely attached and detached. The method described in “0009” is adopted to prevent the drop-down.

By the way, since this support column is a flat plate (stand) column on which a heavy object is loaded, it needs a strength capable of withstanding the weight.
Also, as shown in Fig. 3, when nesting is used for storage, they are stored in layers, so if the column is nested deeply so that the inner wall of the column and the outer wall of the column on the pallet are in contact with each other, the column is removed. As shown in FIGS. 2-b and 3-b, it also serves as a stopper to prevent this, so that it can be withstand the load weight as shown in FIGS. 2-b and 3-b. ) Reinforcement (7) was added to the part.

  In addition, in consideration of the fact that it is piled up outdoors, a water drain hole (8) shown in FIG. The reinforcement (7), which also serves as a stopper that should not be visible, is supplementarily illustrated with a dotted line for easy understanding.

The invention's effect

  Since the present invention is configured as described above, the following effects can be obtained.

  Compared to a conventional wooden pallet, the weight of each unit is lighter, so the workability is better and the durability is improved.

  According to the present invention, it is not difficult to manufacture a pallet of several levels with the strength or size (length x width x height) as an index depending on the weight or volume of the load. It has the effect of creating a lean palette.

  By making the pallet column hollow and using a “nested” structure, the risk of accidents due to lateral displacement and collapse due to stacking during storage could be almost eliminated. In addition, since the total volume of the stack is reduced, a larger number of units can be stacked and stored higher, so that the work space can be secured widely and the space can be used effectively.

Wooden pallets are almost always incinerated when broken. In addition to the waste of resources, it causes atmospheric pollution problems that have become severe in recent years, such as the generation of CO ₂ .
They are sometimes assembled with metal nails, so it is difficult to disassemble and reassemble them, including their costs, and compared to reassembled products (which hardly exist in reality) on wooden pallets. Rather, it depends on what is said to be cheap on a new pallet. In any case, it has an indirect effect to save wood resources and control air pollution.

  Incineration of pallet materials according to the present invention is in the direction of strict regulation because of serious problems such as air pollution, but it is possible to recycle plastics as the main material, and various usage developments are proposed. In the present invention, the specification mainly adopts waste plastics. Of course, not only the main materials but also the aggregates for reinforcement and the weight increase materials for weight reduction and cost reduction are recycled including unused resources. The effect of effectively using resources is created.

  The fact that fumigation processing can be omitted when used for export packaging can reduce costs and troublesomeness, including administrative processing such as procedures related to fumigation processing.
