Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a logistics case made of glass fiber reinforced resin and a method for manufacturing the same. It has a structure that uses recycled synthetic resin as a material, has the same effectiveness, and can be recycled, resulting in low cost and lF saving.
Our goal is to provide a highly original box.

Another object of the present invention is to provide a method for manufacturing a glass fiber reinforced resin box that is easy to manufacture.

As is well known, various types of distribution boxes are currently used, including cardboard boxes, polypropylene boxes, dump plate boxes, and the like.

Conventionally, cardboard boxes have been used in large quantities in the automobile manufacturing industry as well as for transporting fresh foods, household goods, and general consumables.

However, while cardboard has the advantage of being recyclable, it requires stitching at the stage of its construction and also uses tape, etc. for sealing, so it ends up becoming a composite material. However, this tends to increase manufacturing or remanufacturing costs.

'J7t, a cardboard box with excellent weather resistance and impact resistance, is a box with an open top due to its usage.
Since it is a surface box, each edge of the upper edge requires a lip for reinforcement, so straight lips and corner rigs made of steel, aluminum, and buostic materials are used, and the main material and secondary materials are composited. Not only stitching but also
Not only are the main materials expensive, such as riveting, but processing costs also tend to be high.

However, boxes made of dump plates were developed to compete with the plastic boxes described later and are provided in response to various logistics demands, but during the manufacturing process of the boxes, It has the advantage of extremely low mold costs for manufacturing, which makes it possible to form the optimal shape for each persimmon-shaped product to be housed inside, and the disadvantages of the main material and assembly processing costs mentioned above. The use of this product has been expanded by offsetting the above.

These boxes made of cardboard and cardboard are provided as raw materials in the form of plates, and are completed by stamping and assembling and completing the prescribed printing process.On the other hand, what is commonly known as a poly box is made by injection molding (in rare cases, Since the molding method is mainly extrusion molding, it requires a high-precision and high-density mold to withstand strong pressure, which is a disadvantage for manufacturing small quantities of boxes. However, it has the advantage of not requiring an assembly process.

Therefore, this invention takes up the problems regarding the main material and manufacturing method of the box based on the above-mentioned conventional technology as a technical problem to be solved, and the main material has properties different from conventional ones. Glass fiber reinforced resin is used, and in addition to being low-priced due to its high productivity and resource-saving due to its easy recyclability, the box is manufactured using a different structure than conventional ones. The purpose is to improve yields in stamping and cutting, and to provide various logistics materials used in various industrial fields in optimal shapes and configurations at low prices.

Next, embodiments of the present invention will be explained with reference to the drawings. In the figure, the box 11 of this example is made by thermally processing the main material 1 provided in the form of a plate as its right and left sides or both end sides.
A, IB, and the lower body serving as the bottom surface are also made into part 1C using the same processing method, and these parts are assembled to form the part 1C.

FIG. 1 shows a configuration of the box 11 in which the right side body 1B and the left side body 1B have the same shape and are arranged symmetrically. Ru.

In this state, the upper part of the box 11 is completed, and the box 1
The bottom body 1 of the box 11 has the same configuration as the upper and lower edges of 1.
C is fabricated using the same processing method as IA and IB.

At this time, when configuring the box 11, the edges 2 and 10 of IA and IB do not necessarily have to have the same configuration, but from the viewpoint of strength of the box 11 and manufacturing cost. It is desirable that both have the same configuration.

FIG. 2 shows a state in which the main material of the box 11, which is a reinforced resin material made of glass fiber, is provided in the form of a plate after being kneaded and cut into a predetermined size. 1 is a resin material which is the main material, and 10 is a built-in glass fiber.

3 and 4 show the state in which the main material 1 has been heat-processed. Although IA and IB are shown to be symmetrically processed, the edges 2 and 6 have the same dimensions.

FIG. 5 shows a configuration for the purpose of reducing the cost burden of the mold, which is a problem in the manufacturing stage of the box 11, and expanding the application and improving the strength through modularization. ID, I
E is a connection plate and IA.

As with 1B, it is desirable to have a symmetrical shape and insert it in the direction of the long edge.

Further, this configuration can be applied to the bottom portion 1C of the box 11, and the effects are the same.

Note that there are parallel methods and cross-over methods for this modularization, which may be used depending on the required level of quality and strength.

FIG. 6 shows a configuration for improving the strength of the bond when bonding the edges. 4 is a convex portion, and 5 is a concave portion.

Figure 7 shows that the dimensions of each side are not symmetrical with respect to Figures 3 and 5, but are symmetrical. This is advantageous when simplifying the module due to the nature of the article.

Moreover, FIG. 8 shows a case in which the face piece is a closed type six-sided box, taking advantage of the fact that it is symmetrical at the stage of molding.

As explained above, the present invention, when manufacturing a distribution box using a resin material reinforced with glass fibers, separates the right side and left side of the box, and separates the right side and left side of the box. In response to molding with a symmetrical object, the lower body that becomes the bottom surface is molded separately, and the both side bodies and the lower body are fused using a heating machine, which reduces the investment cost of the mold. The versatility achieved by modularizing the mold is different from traditional box manufacturing methods, and it greatly contributes to various logistics systems. Note that conventional stitching, lip jointing, etc. (not shown) are also fully possible due to the configuration of each edge of the present invention.

The present invention focuses on strength and recyclability as characteristics of glass fiber reinforced resin materials, and ultimately aims to save resources through recycling, but as a preliminary step, it aims to reduce investment by modularizing the mold, and The advantages of symmetrically separating the right and left sides of the mold are the reduction in the number of man-hours required for manufacturing the mold, and the reduction in time. l
By providing these advantages to the market, it will have an excellent effect on overall logistics improvement.
