Description

  The present invention relates to a glass substrate storage container, and more particularly to a technique for preventing contact between glass substrates stored in a storage container and improving work efficiency when storing the substrates.

  As is well known, glass substrates used in various displays such as liquid crystal displays, plasma displays, field emission displays, organic EL displays, and touch panels, and glass substrates used as cover glasses are increasing in demand for lighter body devices. Along with this, thinning has been promoted.

  When transporting the glass substrates as described above, a plurality of glass substrates are used as a set, and the substrates are stored in a dedicated storage container, arranged in parallel in an upright posture (upright posture). It is common.

  However, as described above, the following problems have arisen when transporting the glass substrate because the glass substrate is being made thinner.

  That is, since the thin glass substrate has flexibility as its characteristic, the substrate bends or bends due to vibration during transportation or external impact. As a result, there is a problem in that the substrates stored in the storage container come into contact with each other, and the substrate is scratched or cracked, resulting in a decrease in the quality of the substrate.

  In order to cope with such a problem, the following Patent Document 1 discloses a glass composed of an inner box that houses a glass substrate, an outer container that has an opening and accommodates the inner box, and a lid that closes the opening. A substrate storage container is disclosed. The storage container is formed with a storage groove for storing the substrate on the inner side surface of the inner box, has a bottom receiving portion that contacts the bottom edge of the substrate at the lower end of the storage groove, and the lid is a corner portion of the substrate ( It has a pressing piece for holding the upper edge) and the periphery of the joint between the upper edge and the side edge connected to the upper edge. And it becomes the structure by which a pair of inclined surface which clamps a board | substrate is provided in each of a storage groove, a bottom receiving part, and a pressing piece.

  According to the glass substrate storage container disclosed in the document, a pair of inclined surfaces that sandwich the substrate are provided in each of the storage groove, the bottom receiving portion, and the holding piece, so that the substrate being transported vibrates. It is hard to bend or bend due to shock from the outside. For this reason, a board | substrate can be stably hold | maintained in a storage container and it is possible to prevent the stored board | substrates between contacts effectively.

  However, even with the glass substrate storage container disclosed in Patent Document 1, there is still a problem to be solved.

  That is, when a thin glass substrate is stored in the glass substrate storage container disclosed in the same document, the upper edge portion of the stored substrate protrudes from the inner box. Edge is easy to bend. For this reason, it becomes difficult to smoothly fit the corner portions (both the upper edge portion and the side edge portion) of the substrate with respect to the pair of inclined surfaces provided in the pressing piece. As a result, there has been a problem that it takes time to store the glass substrate, and the efficiency of the operation tends to deteriorate.

  In addition, the holding piece provided in the glass substrate storage container disclosed in the same document is covered with the lid, and the holding piece is attached to the corner of the substrate because of being attached to the lid. At this time, it is difficult for the operator to visually confirm the relative positional relationship between the inclined surface provided on the pressing piece and the upper edge portion and the side edge portion of the substrate stored in the inner box. This made the above problem more prominent.

  Under such circumstances, the present situation is that it is insufficient from the viewpoint of the efficiency of the storing operation only to prevent contact between the substrates stored in the storage container, which has been a problem in the past.

  This invention made | formed in view of the said situation makes it a technical subject to aim at the improvement of the working efficiency at the time of accommodation of a board | substrate, preventing the contact of the glass substrates accommodated in the storage container.

  The present invention, which was devised to solve the above problems, includes a box body in which a storage groove for vertically storing a glass substrate is formed on an inner surface and a bottom surface, and an upper edge portion of the glass substrate stored in the box body. Corner holding with a corner holding groove for holding a corner between the top plate on which the upper edge holding groove to be held is formed and the side edge that is connected to the upper edge and the upper edge of the glass substrate. A glass substrate having a member and a lid that covers the top of the box through a top plate and a corner holding member, and the top surface of the top plate and the corner holding member and the ceiling surface of the lid are arranged to face each other The storage container is characterized in that the top surface of the top plate and the corner portion holding member and the ceiling surface of the lid body can be connected and detached via the detachable member.

  According to such a configuration, when the glass substrate is stored in the storage container, the lid body, the top plate, and the corner portion holding member can be coupled and detached by the detachable member, so that the glass substrate is stored in the box body. It becomes possible to hold the upper edge portion and the corner portion of the substrate only with the top plate and the corner portion holding member in a state of being detached (detached) from the lid. Thus, when it is going to hold | maintain the upper edge part and corner | angular part of a board | substrate in the state which removed the top plate and the corner | angular part holding member from the cover body, the upper edge part formed in the upper edge part of the board | substrate and the top plate. An operator can easily visually confirm the holding groove and the relative positional relationship between the corner portion and the corner portion holding groove formed in the corner portion holding member. In addition to this, if the top plate is first attached to the substrate, and then the corner holding member is attached to the substrate, when attaching the top plate, only the upper edge of the substrate is attached to the top plate. It is only necessary to fit the formed upper edge holding groove. For this reason, even if it is a case where the upper edge part of the thin glass substrate which is easy to bend is hold | maintained at a top plate, it becomes possible to fit an upper edge part smoothly into an upper edge part holding groove. In addition, since the top plate is mounted first, when the corner holding member is mounted on the substrate, the upper edge portion and the side edge portion of the substrate are more difficult to bend. Can be attached to. Furthermore, the above-described detachable member is disposed between the top surface of the top plate and the corner portion holding member and the ceiling surface of the lid body, so that the top edge portion and the corner portion of the substrate housed in the box body are attached to the top portion and the corner portion. After mounting the plate and the corner holding member, simply cover the top of the box with the lid via the top plate and the corner holding member, and the lid can be easily attached to the top plate and the corner holding member by the detachable member. Thus, the substrate storing operation can be completed. Therefore, it is possible to improve the efficiency of the substrate storing operation. In addition, a storage groove is formed on the inner side surface and bottom surface of the box, a corner holding groove is formed on the corner holding member, and an upper edge holding groove is formed on the top plate. Can be held stably. Therefore, it is possible to suitably prevent a situation in which the stored substrates come into contact with each other due to vibration during transportation or impact from the outside, and scratches or cracks occur. On the other hand, since the storage container has both the top plate and the corner holding member, there is a concern that a positional deviation may occur between the upper edge holding groove and the corner holding groove. Concerns are appropriately eliminated as follows. That is, under the state where both the top plate and the corner portion holding member are coupled to the lid, the relative positional relationship between the top plate and the corner portion holding member does not change. This makes it difficult for the groove to be displaced between the upper edge holding groove formed on the top plate and the corner holding groove formed on the corner holding member. As a result, it is possible to avoid the problem of damage.

  In the above configuration, the detachable member is preferably a hook-and-loop fastener.

  In this way, the attachment and detachment of the lid and the top plate, and the lid and the corner portion holding member become smoother, so that the above-described effects can be further enhanced.

  In the above configuration, the length of the upper edge holding groove of the top plate is preferably 50% or more of the length of the upper edge of the glass substrate.

  In this way, when the top plate is mounted on the substrate when the glass substrate is stored, the upper edge portion of the substrate and the side edge portion connected to the upper edge portion are more difficult to bend. The mounting of the members becomes easier. Thereby, it is possible to further improve the efficiency of the storing operation.

  In the above configuration, it is preferable that a lateral gap is formed between the top plate and the corner holding member, and a vertical gap is formed between the box and the corner holding member. Here, the “lateral direction” refers to the longitudinal direction of the upper edge portion of the glass substrate stored in the glass substrate storage container, and the “vertical direction” refers to the longitudinal direction of the side edge portion of the glass substrate. (same as below)

  In this way, when the glass substrate is transported, it is possible to prevent the top plate and the corner holding member and the box and the corner holding member from interfering with each other due to vibrations or external shocks. The positional deviation of the groove is less likely to occur between the groove and the corner holding groove and between the storage groove and the corner holding groove.

  Said structure WHEREIN: It is preferable that the length of the vertical direction inside a box is 80% or more and 95% or less with respect to the length of the vertical direction of a glass substrate.

  In this way, the upper edge portion of the glass substrate that protrudes upward from the box and the margin of the side edge portion connected to the upper edge portion are reduced, so that the upper edge portion and the side edge portion of the substrate are not easily bent. Become. Thereby, it becomes possible to improve the work efficiency at the time of accommodating a board | substrate in a storage container.

  As described above, according to the present invention, it is possible to improve work efficiency when storing substrates while preventing contact between the glass substrates stored in the storage container.

  Hereinafter, a glass substrate storage container according to an embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a perspective view showing a state in which a glass substrate storage container according to an embodiment of the present invention is disassembled. As shown in the figure, a glass substrate storage container 1 (hereinafter simply referred to as a storage container 1) includes a box body 2 that stores glass substrates G in a vertical position, and an upper edge of the glass substrate G that is stored in the box body 2. The top plate 3 attached to the portion U, the two corner holding members 4 attached to the corner C between the upper edge U and the side edge S of the glass substrate G, the top plate 3 and the corner It is comprised with the cover body 5 which covers the holding member 4 and the upper part of the box 2. As shown in FIG.

  On the pair of opposed inner side surfaces 2a and bottom surface 2b of the box body 2, storage grooves D1 for storing the glass substrates G vertically are formed at equal intervals in the width direction of the grooves. The storage groove D1 formed on the inner side surface 2a is formed in a straight line over the entire area of the inner side surface 2a in the height direction, and the storage groove D1 formed on the bottom surface 2b of the box body 2 is formed on the glass substrate G.

It is formed in a straight line over the entire region along the direction. In addition, four hook-and-loop fasteners M are attached to the top surface of the top plate 3 as detachable members that are coupled to and detached from the ceiling surface of the lid 5. The top plate 3 is made of foamed polyethylene.

  The corner holding grooves D3 are formed on the inner side surfaces of the two corner holding members 4, and the corner holding grooves D3 are formed along the upper edge U and the side edge S along the glass substrate G. Are formed in a straight line over the entire area. In addition, two hook-and-loop fasteners M are attached to the upper surface of the corner holding member 4 as detachable members that are coupled to and detached from the ceiling surface of the lid 5. In addition, the material of the corner | angular part holding member 4 is also a foamed polyethylene.

  On the ceiling surface of the lid 5, four hook-and-loop fasteners M were attached to positions facing the hook-and-loop fastener M attached to the top plate 3 and attached to the two corner holding members 4. Two (four in total) hook-and-loop fasteners M are attached to positions facing the hook-and-loop fastener M, respectively. Further, the longitudinal length of the portion of the lid 5 that covers the corner holding member 4 is longer than the length of the corner holding member 4 in the longitudinal direction. The material of the lid 5 is foamed polypropylene.

  The number of grooves and the groove shape of the storage groove D1, the upper edge holding groove D2, and the corner holding groove D3 are the same.

  FIG. 2 is a cross-sectional view showing a state in which the glass substrate G is stored in the storage container 1. As shown in the figure, the upper edge U of the glass substrate G stored in the box 2 protrudes upward from the box 2. Further, there is a lateral direction (between the top plate 3 mounted on the upper edge U of the glass substrate G and the corner holding member 4 mounted on the corner C of the upper edge U and the side edge S ( A gap V in the horizontal direction is formed, and a gap V in the vertical direction (vertical direction) is formed between the box 2 and the corner portion holding member 4.

  Here, as a size of the glass substrate G accommodated in the storage container 1, length: 900mm-1100mm, width: 600mm-800mm is preferable, More preferably, length: 900mm-1000mm, width: 650mm-750mm. The thickness of the glass substrate is preferably 0.3 mm to 0.7 mm. Further, the groove widths of the storage groove D1, the upper edge holding groove D2, and the corner holding groove D3 are preferably 1.5 mm or less, and more preferably 1.0 mm or less. In addition, when each said groove | channel hold | maintains the glass substrate G, you may make it provide a play between each groove | channel and the glass substrate G. FIG. Furthermore, the length of the upper edge holding groove D2 is preferably 50% or more of the length of the upper edge U of the glass substrate G, and more preferably 60% or more. Further, the height of the box body 2 (height of the inner side surface 2a) with respect to the length of the glass substrate G in the vertical direction is preferably 80% or more and 95% or less. In addition, the width of the gap V is preferably 1.5 mm or less, and more preferably 1.0 mm or less.

  Hereinafter, the implementation situation at the time of accommodating the glass substrate G in said accommodation container 1 is demonstrated based on attached FIG. The size of the glass substrate G stored in the storage container 1 is vertical: 920 mm, horizontal: 730 mm, and plate thickness: 0.3 mm.

  First, as shown in FIG. 3, the side edge S of the glass substrate G is fitted into the storage groove D1 formed on the pair of inner side surfaces 2a of the box 2, and the glass substrate G is inserted into the storage groove D1 formed on the bottom surface 2b. The glass substrate G is stored vertically in the box 2 by fitting the bottom edge portion B of the glass substrate G.

  Next, as shown in FIG. 4, the top plate is fitted by fitting the upper edge holding groove D <b> 2 formed in the top plate 3 along the upper edge U of the glass substrate G housed in the box 2. 3 is attached to the upper edge U. At this time, since the upper edge portion U of the glass substrate G is held by the top plate 3 alone, the relative relationship between the upper edge portion U of the glass substrate G and the upper edge portion holding groove D2 formed in the top plate 3 is relatively small. The positional relationship can be easily confirmed visually. Further, only the upper edge portion U of the glass substrate G may be fitted into the upper edge portion holding groove D <b> 2 formed in the top plate 3. For this reason, even when the upper edge U of the thin glass substrate G that is easily bent is held by the top plate 3, the upper edge U can be smoothly fitted into the upper edge holding groove D2.

  When the mounting of the top plate 3 is completed, as shown in FIG. 5, the corner holding groove D <b> 3 formed in the corner holding member 4 is placed between the upper edge U and the side edge S of the glass substrate G. The corner portion holding member 4 is attached to the corner portion C of the glass substrate G by fitting into the corner portion C of the glass substrate G. At this time, as described above, since the top plate 3 is attached to the upper edge portion U of the glass substrate G in advance, the upper edge portion U and the side edge portion S are difficult to bend. The part holding member 4 can be mounted.

  Finally, the top plate 3, the corner holding member 4, and the upper part of the outer side surface 2 c of the box body 2 are covered with the lid body 5, whereby the glass substrate G is stored. At this time, since the surface fastener M is provided on each of the top plate 3, the corner holding member 4, and the lid 5, the following preferable mode is obtained. That is, if the lid 5 covers the top plate 3, the corner holding member 4, and the outer side surface 2 c of the box body 2, the surface fasteners M provided in each member abut on each other, and the top plate 3 and the corner The lid 5 can be easily coupled to the part holding member 4 and the operation of storing the glass substrate G can be completed. When the storage operation is completed, the state shown in FIG. 2 is obtained as already described in the description of the configuration of the storage container 1 described above.

  As described above, the glass substrate G stored in the storage container 1 includes the storage grooves D1 of the inner surface 2a and the bottom surface 2b of the box 2, the upper edge holding groove D2 of the top plate 3, and the corner portion holding member 4. It is stably held by the corner holding groove D3. For this reason, it can prevent effectively that the glass substrates G accommodated by the vibration in transportation and the impact from the outside contact. Further, since the gap V is formed between the top plate 3 and the corner holding member 4 and between the box 2 and the corner holding member 4, the above members can be prevented from interfering with each other. Misalignment of the groove is less likely to occur between the edge holding groove D2 and the corner holding groove D3, and between the storage groove D1 and the corner holding groove D3. As a result, it is possible to suppress the possibility that the glass substrate G is scratched or cracked.

  Hereinafter, the implementation situation at the time of taking out the glass substrate G from said storage container 1 is demonstrated based on attached FIG. 2, FIG.

  The glass substrate G stored in the storage container 1 is in the state shown in FIG. 2 as already described as the configuration of the storage container 1 described above.

  If the lid 5 is lifted upward from this state and removed from the box 2, the top plate 3 and the corner holding member 4 attached to the lid 5 are similarly lifted and removed as shown in FIG. 6. At this time, since the surface fastener M is provided on each of the top plate 3, the corner portion holding member 4, and the lid body 5, the following preferable mode is obtained. That is, due to the presence of the hook-and-loop fastener M, it is possible to prevent the top plate 3 and the corner portion holding member 4 from being detached from the lid 5 when the lid 5 is lifted. As a result, it is possible to prevent the glass substrate G from being damaged due to the impact of the top plate 3 and the corner portion holding member 4 being dropped, so that the factor that causes the quality degradation of the glass substrate G is accurately eliminated.

  As described above, after removing the lid 5 and the top plate 3 and the corner portion holding member 4 attached to the lid 5, the glass substrate G can be obtained by pulling the glass substrate G stored in the box 2 upward. The removal operation of G is completed. At this time, since the upper edge portion U of the glass substrate G protrudes upward from the box 2, it becomes easy to take out the glass substrate G, and therefore it is possible to improve the efficiency of taking out the glass substrate G. It becomes.

  Here, the configuration of the glass substrate storage container according to the present invention is not limited to the storage container 1 according to the above embodiment. In the above embodiment, the storage grooves D1 formed on the inner side surface 2a of the box body 2 are formed continuously over the entire area of the inner side surface 2a in the height direction, but the storage grooves formed on the bottom surface 2b. As in D1, the storage grooves D1 may be separated from each other. Moreover, you may form the accommodation groove | channel D1 formed in the bottom face 2b of the box 2 continuously like the accommodation groove | channel D1 formed in the inner surface 2a. The upper edge holding groove D2 formed on the top plate 3 and the corner holding groove D3 formed on the corner holding member 4 are also formed in the same state as the storage groove D1 formed on the bottom surface 2b. May be. Furthermore, the shape of the storage groove D1, the upper edge holding groove D2, and each part holding groove D3 may not be the same. In addition, in the said embodiment, although the hook_and_loop | surface fastener M is used as an attachment / detachment member which makes the top plate 3, the corner | angular part holding member 4, and the cover body 5 detachable, it is not this limitation, It uses an adhesive. You may make it perform attachment and detachment. In this case, the pressure-sensitive adhesive may be applied to any one of the top plate 3, the corner portion holding member 4, and the lid 5, or may be applied to both.
