[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a transport box with a fork guide in a box composed of a bottomed box body made of a resin foam and a lid.
[0002]
[Prior art]
Conventionally, for example, a box as shown in FIG. 8 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. 8, 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 the main-body part 02, a cover body, and the interior board 04 are also a resin foam, they have heat retention and cushioning properties, and can absorb a shock even when an impact or vibration is applied. Further, in the transport box 01 for transporting such a glass substrate 03 or the like, concave gripping portions 05 for inserting and carrying a hand are formed on both outer side surfaces for easy carrying.
[0004]
[Problems to be solved by the invention]
However, the relatively light and small transport box 01 as described above can be transported by human power, but a heavy transport box such as a forklift or a crane is used for a heavy transport box.
[0005]
However, the transport box 01 having the structure shown in FIG. 8 is not provided with a locking projection or a lifting tool on the outer surface, so that the transport box is placed on a pallet and transported by a forklift or a crane. In order to transport the product in the transport box, a method of lifting and transporting the wire from the bottom of the transport box will be adopted. However, in this transport method, not only is it troublesome during transport, but the transport box moves on the pallet. Or the glass substrate 03 housed inside may be damaged when tilted.
[0006]
The present invention has been made paying attention to such a problem, and can safely and reliably transport a fragile thin plate-like transported object such as a glass substrate accommodated therein, and has a heat insulating material having rigidity. An object of the present invention is to provide a transport box with a fork guide that is highly effective.
[0007]
[Means for Solving the Problems]
In order to solve the above problem, fork guided transport box of the present invention, the fork guided transport box fitted with fork guide the transport box consists of a box present body and the lid body with a bottom made of resin foam The fork guide is fixed around the outer periphery of the box body, and the box body has a laminated structure in which both sides of the resin foam are sandwiched between aluminum composite plates, and one end is locked to the fork guide. The fork guide is fixed to the box main body by the other tip of the fixture passing through one of the aluminum composite plates and locking with the resin foam .
According to this feature, since the fork guide is fixed so as to surround the outer periphery of the box body, not only the strength of the transport box is improved, but also the fork guide can be used when transporting using the transport machine. Therefore, it can be efficiently transported without taking time and effort. In addition, the aluminum composite plate not only reinforces the fork guide attachment, but also has a heat insulating effect because both sides of the foamed polyethylene resin are sandwiched by aluminum. Furthermore, since the tip of the fixture stops at the resin foam and does not reach the inner aluminum composite plate, it is possible to suppress the external force received from the outside from being transmitted to the inner transported body.
[0009]
The transport box with a fork guide according to the present invention is preferably formed by applying conductive treatment means to the outermost and innermost surfaces of the aluminum composite plate.
In this way, double antistatic means are applied to the inner and outer layers, so that dust can be prevented from adhering to the conveyed object due to static electricity.
[0011]
In the transport box with a fork guide according to the present invention, it is preferable that the bottomed box body is reinforced by a frame made of aluminum .
In this way, since the transport box is reinforced with a frame made of aluminum , a robust box can be provided, and the box will not be deformed even in contact with other articles or for long-term storage. .
[0012]
In the transport box with a fork guide according to the present invention, it is preferable that a plurality of grooves capable of holding thin bodies such as glass substrates one by one are formed inside the bottomed box body.
In this way, since a thin body such as a glass substrate is held one by one by a plurality of grooves formed inside the box body, even if an external force is applied to the box, the lateral direction of the thin body is reduced. The movement is restricted and it can be transported safely and reliably.

[0034]
When the bottom surface pad 44 and the side surface pads 48 are attached, the plurality of parallel grooves 42 and 46 of the bottom surface pad 44 and the side surface pads 48 shown in FIG. 5 are set so as to correspond accurately.
[0035]
Thus, by sticking the bottom surface pad 44 and the both side surface pads 48, the lower ends of the plurality of thin glass sheets G are supported on the bottoms of the parallel grooves 42 of the bottom surface pad 44 as shown in FIGS. In the parallel groove 46 of the side surface pad 48, both side ends G2 of the thin glass sheet G are engaged and held in a state where a slight gap S (see FIG. 6) is formed with respect to the groove bottom.
[0036]
Further, as shown in FIGS. 1 and 5, the box body 2 has a pair of connecting tools 50 (for example, patchon locks) attached to both sides of the side surfaces of the long upper frames 24a and 24b, which are open ends. Guide members 52 that guide the outer periphery of the lid 3 when opening and closing the lid 3 up and down are attached to the adjacent positions on both outer sides of the connecting tools 50 and the sides of the short upper frames 22a and 22b. Yes. The connecting tool 50 is pivotally mounted in a state where a biasing force is applied to the mounting surface by a coil spring (not shown).
[0037]
On the other hand, on the outer periphery of the lid 3, as shown in FIG. 1 (b), each pair of connected tools is in a positional relationship corresponding to the connecting tool 50 of the box body 2 on both sides of the long side frames 36 a and 36 b. 54 is attached, and a handle 56 is attached to the center of the short side frames 34a and 34b.
[0038]
Further, as shown in FIG. 6, an upper surface pad 58 formed in a rectangular parallelepiped shape having a predetermined thickness made of, for example, a polyethylene foam that is softer than the bottom surface pad 44 is formed on the back surface of the top plate 32 of the lid 3. Are attached in parallel at predetermined intervals (for example, at three locations).
[0039]
As shown in FIGS. 1B to 6, the upper surface pad 58 is formed thicker than the height of the side plates 34a, 34b and 36a, 36b on the outer periphery of the lid 3, and protrudes from the side plates 34a, 34b and 36a, 36b. The flat surface is configured as a pressing surface 58 a that presses the upper edge of the thin glass G accommodated and held in the box body 2.
[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. 5 and FIG. 7, and one side of both 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, and the lower ends thereof are the corresponding parallel grooves of the bottom surface pad 44. While being supported by the groove bottom of 42, both side edges of the thin glass G are held in a state where a slight gap S is formed with respect to the groove bottoms of both parallel grooves 46 (see FIG. 6).
[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]
When the lid 3 is closed, the fitting recess 38 of the side frame 34b around the lid 3 is inserted into the upper end portion of the upper frame 22b of the box body 2 opening as shown in FIG. The other side frames 34a, 36a, 36b are also inserted into the upper frames 22a, 24a, 24b, respectively.
[0044]
In this state, the packing 40 in the fitting recess 38 of the lid 3 is compressed, and at the same time, the pressing surface 58a of the upper surface pad 58 is supported by the groove bottom of the parallel groove 42 of the bottom surface pad 44. It contacts the upper edge G1 (see FIG. 6).
[0045]
Here, when closing the lid 3, the lid 3 is supported by a conveying device (not shown), and the lid 3 is guided by the guide member 52 from the top as shown in FIG. In the operation of moving downward while being guided, the connected tools 54 on both sides push the connecting tool 50 against the urging force and then are engaged and held by the linking tool 50 again by the action of the urging force.
[0046]
Thus, when the lid 3 is engaged and held by the connector 50, the fitting recess 38 of the side frame 34b of the lid 3 and the upper end portion of the upper frame 22b are inserted as shown in FIG. At the same time, the upper and lower end portions of the thin glass sheet G are sandwiched between the groove bottom of the corresponding parallel groove 42 of the bottom surface pad 44 and the pressing surface 58a of the upper surface pad 58 of the lid 3. Retained.
[0047]
In this way, the transport box 1 containing a plurality of thin glass sheets G by closing the lid 3 is transported by a transport machine such as a forklift or a crane at the time of transport, but is transported using a forklift. In this case, the fork guide 26 or the fork guides 26 and 28 having a flange shape are transported while being locked with the fork.
[0048]
Alternatively, when transporting using a crane or the like, the wire is lifted and transported by locking a wire or the like to a pair of lifting eyebolts 30 provided on the fork guide 26.
[0049]
Therefore, according to the transport box of the present invention, since the fork guides 26 and 28 are fixed so as to surround the outer periphery of the box body 2, not only the strength of the transport box 1 is improved, but also a transport machine such as a forklift or a crane. When transporting using a fork guide or the like, it can be transported efficiently without trouble.
[0050]
In addition, the transport box 1 has a triple heat insulating structure in which a flexible heat insulating material is sandwiched between aluminum composite plates as a plate body constituting a bottomed box body. It is difficult to transmit force directly to the. Moreover, even if thermal stress acts on the aluminum composite plate 7 due to changes in the outside air temperature, there is no soft heat insulating layer in the middle, so that no force is transmitted to the transported body.
[0051]
Moreover, when foamed polystyrene is used as a flexible heat insulating material, the box body can be constructed as a lightweight and robust heat insulating plate that is less susceptible to changes in the outside air temperature.
[0052]
Moreover, since the aluminum composite plate 7 has a cross-sectional structure in which the aluminum plates 7a and 7b are bonded to both sides of the foamed polyethylene resin via the urethane adhesive 11 and the foamed polyethylene resin 5 is sandwiched therebetween, heat insulation and reinforcement Has an effect.
[0053]
Furthermore, since the polyester resin-based baking paint 13 is baked and applied to the outermost surface and the innermost surface of the aluminum composite plate 7, it has an antistatic effect for a long period of time without peeling off the paint, and is troublesome to manufacture. It can be finished evenly.
[0054]
In addition, the bottomed box body 2 is framed by upper frames 22a, 22b, 24a, 24b and a frame pillar 20 or a pair of bottom frames 10a, 10b and 12a, 12b made of hard aluminum or the like, and the vertical side plate 8a, A pair of side surface pads 48 formed with a plurality of parallel grooves 46 for guiding the glass substrates G one by one are disposed inside 8b. The bottom plate 4 of the box body 2 and a material more flexible than the bottom plate 4 are disposed. It can be provided as a robust box in which the glass substrate G is sandwiched between the lid 3 and the box is not deformed even in contact with other articles or in long-term storage, even if an external force acts on the box. Even in this case, the glass substrate G and the like can be stored and transported in the transport box in a stable state without being damaged.
[0055]
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.
[0056]
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.
[0057]
Further, 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 14a, 14b, 16a, 16b and the bottom frames 10, 12 through the respective joint angle frames, and 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.
[0058]
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, the number of fork guides 26 and 28 attached to the upper and lower sides of the outer periphery of the side wall of the box body 2 is as follows. Depending on the size, shape, and weight of the box body 2, it can be appropriately selected at the time of designing. In addition, although two aluminum composite plates are used according to the inside and outside, it is also possible to use several layers in order to increase the reinforcing strength, and there are changes and additions within the scope not departing from the gist of the present invention. Even if it exists, it is included in this invention.
