BACKGROUND OF THE INVENTION
The present invention relates to a transport box including a box body with a bottom and a lid.
[0002]
[Prior art]
Conventionally, for example, a box as shown in FIG. 7 has been known as a transport box used when transferring a glass substrate such as a glass substrate for liquid crystal display.
[0003]
In FIG. 7, reference numeral 01 denotes a transport box, which is composed of a bottomed main body 02 and a lid (not shown), and a pair of interior plates 04 having a glass substrate supporting groove 04 a are provided in the main body 02. Has been inserted. The glass substrate 03 is engaged and supported one by one in the groove 04a of the facing interior plate 04, and the lid is placed on the main body portion 02 so as to hold the upper side of the glass substrate 03 from the upper part and is transported. . And since all the main-body part 02, a cover body, and the interior board 04 are resin foams, they have cushioning properties, and even when an impact or vibration is applied, they can be absorbed with cushioning properties.
[0004]
[Problems to be solved by the invention]
However, since the conventional transport box is formed of resin foam for the main body part 02, the lid body, and the interior board 04, there is a certain degree of heat retention, but sufficient heat insulation function when the outside air temperature changes extremely Did not have. In particular, when transporting to an extremely cold region, moisture contained in the air in the transport box may condense and adversely affect the transported body. In addition, when an external force is applied from the outside, the force is transmitted to the transported body via the resin foam and may be damaged.
[0005]
The present invention has been made paying attention to such problems, and even when the outside air temperature changes extremely, it has a large heat insulation effect so that the inside of the transport box can be maintained at a predetermined temperature, and is damaged. The purpose of the present invention is to provide a transport box with a low risk of occurrence.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, a transport box according to the present invention is a transport box including a bottomed box body and a lid, and at least the bottomed box body is formed of a plurality of plate bodies. at least one body, intermediate the Ri formed by sandwiching a foamed polyethylene resin from both sides to place the flexible insulation material with aluminum composite plate was sandwiched between aluminum from both sides, said plate member, said aluminum composite tip is outwardly It is characterized in that it is connected to an external accessory provided outside the box body with a fixture that penetrates the plate and is locked by the heat insulating material .
According to this feature, since the heat insulation layers are tripled, the heat insulation effect is great, and the intermediate part is made of a flexible heat insulating material, so that even if external force is applied from the outside, direct force is applied to the conveyed object. Not transmitted. And since the aluminum composite board has pinched the both sides of the foamed polyethylene resin with aluminum, there exists a heat insulation effect and a reinforcement effect. In particular, even when thermal stress is applied to the aluminum composite plate due to changes in the outside air temperature, energy is absorbed by the flexible heat insulating material at the intermediate portion, and no force is directly applied to the conveyed object. In addition, even when attaching external accessories to the plate body, the mounting force such as rivets does not penetrate through the two aluminum composite plates sandwiching the flexible heat insulating material such as polystyrene foam, so that external force is applied through the mounting tool. It is not transmitted to the conveyed product.
[0007]
In the transport box of the present invention, the flexible heat insulating material is preferably a foamed polystyrene resin.
In this case, the box body can be constructed of a lightweight and robust heat insulating plate that is less susceptible to changes in the outside air temperature because it is composed of a foamed polystyrene having a heat insulating effect and an aluminum composite plate.
[0009]
The transport box of the present invention is preferably formed by applying conductive treatment means to the outermost and innermost surfaces of the plate.
In this way, since the double antistatic means are provided on the inner and outer surfaces, it is possible to avoid the adhesion of dust to the conveyed object due to static electricity.
[0012]
In the transport box of the present invention, the bottomed box body is framed by a frame made of aluminum or the like, and a plurality of grooves for guiding thin bodies such as glass substrates one by one are formed inside the plate body. Preferably, the pair of side plates is disposed, and the thin body is sandwiched between the bottom plate of the box body and the lid made of a material more flexible than the bottom plate.
In this way, since the transport box is reinforced with a frame made of aluminum or the like, a robust box can be provided, and the box may be deformed even when in contact with other articles or for long-term storage. Even if an external force acts on the box, it can be stored and transported in the transport box in a stable state without damaging a thin body such as a glass substrate.

It is configured as a pressing surface 58a that presses the upper edge of G.
[0040]
Next, the function of the transport box configured as described above will be described.
[0041]
First, the state in which the lid 3 of the transport box 1 is opened is shown in FIG. 1B, FIG. 2 and FIG. 3, and one side of the side pads 48 attached to the inner surfaces of the side plates 8a and 8b ( The side edges of the thin glass G supported in a vertical and parallel state by a special fork (not shown) are inserted into the parallel grooves 46 one by one from the upper side in order from the side plate 6a side), and the lower ends are parallel grooves corresponding to the bottom surface pads 44. While being supported by the groove bottom of 42, both side edges of the thin glass sheet G are held in a state in which a slight gap S is formed with respect to the groove bottoms of both parallel grooves 46 [see FIG. 4 (a)].
[0042]
When the thin glass sheet G is supported in a parallel state at a predetermined interval in all the parallel grooves 42 and 46 of the bottom surface pad 44 or the both side surface pads 48 inside the box body 2, the opening end of the box body 2 becomes the lid 3. It is blocked by.
[0043]

[0052]
Further, the glass substrate G is sandwiched so as to be pressed by an upper surface pad 58 made of a polyethylene foam, which is a flexible material, as compared with a bottom surface pad 44 made of a polypropylene foam whose upper side supports the lower side. Since it is free, even when a strong impact is applied from the outside, energy is absorbed by the flexible material so that no force is transmitted to the glass substrate G, so that the glass substrate G is not damaged. be able to.
[0053]
And since the soft material which supports the upper side and lower side of the glass substrate G is comprised by the polyethylene-type foam or the polypropylene-type foam, the lightness which a foam has, the resistance with respect to a friction and a crack, and cushioning property Can be used to transport the glass substrate G safely and reliably.
[0054]
Further, when each of the glass substrates G is carried into and out of the box body 2, each of the glass substrates G is guided to the plurality of parallel grooves 46 of the side surface pads 48 adhered to the inner surfaces of the pair of side plates 8a and 8b. When the glass substrate G is carried in and out of the box body 2, the left and right parallel grooves 46 function as guides, so that the glass substrate G can be easily put in and out.
[0055]
In addition, the bottomed box body 2 includes four corner-shaped pad-shaped reinforcing corner plates 18 that reinforce the bottom plate 4, strip-shaped reinforcing plates 14 a, 14 b, 16 a, 16 b, and the bottom frames 10, 12 to each joint angle frame, In addition, since the frame is reinforced by the frame body composed of the four frame pillars 20 and the upper frames 22a, 22b and 24a, 24b, the robust box body 2 can be provided, and can be provided for contact with other articles and for long-term storage. However, the box body 2 is not deformed.
[0056]
Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments. For example, two aluminum composite plates are used in both the inside and outside, but the reinforcing strength is increased. It is also possible to use several layers in order to increase the number, and changes and additions within the scope not departing from the gist of the present invention are also included in the present invention.
