Description

  The present invention relates to an improvement in packing technology for stacking and packing a plurality of glass plates when transporting the glass plates.

  As is well known, various glass plates have recently become more popular, as represented by glass substrates for flat panel displays (hereinafter referred to as FPD) such as liquid crystal displays, plasma displays, electroluminescence displays, and field emission displays. The reality is that there is a demand for larger size and thinner walls.

  When transporting this type of glass plate, prior to the transport, a plurality of glass substrates are placed vertically on a pallet with a protective sheet such as paper or foamed resin sheet interposed between them (substantially vertical posture). ) (Hereinafter simply referred to as a glass plate laminate) is known (for example, see Patent Document 1). However, in this type of packing form, it is customary to transport the glass plate in a bare state or in a state where it is simply covered with a plastic bag or the like. It is easy to get scratched. Such dirt and scratches can be fatal defects for glass plates that require strict surface cleanliness, such as FPD glass substrates.

  Therefore, for example, as disclosed in Patent Document 2, a hermetically sealed glass plate packaging box in which a glass plate laminate is covered with a box has been proposed. That is, in this document, first, the bottom side of the glass plate laminate placed on the base part (pedestal) is received by the bottom side support part (bottom support plate), and the back side is the back support part (back support plate). In this state, by pressing the front surface of the glass plate laminate with a pressing member to fix the glass plate laminate, and finally, attaching the box body opened at the bottom to the base and covering the glass plate laminate, The glass plate is protected from dirt and scratches caused by dust. The presser member is attachable and detachable in the vertical direction with respect to the pillars provided upright at both corners behind the base part.

Further, from the viewpoint of improving the workability of the unpacking operation, the glass plate packing box disclosed in the same document has a holding member protruding from the inner surface of the box to engage the presser member and lift the box upward. It is equipped. And at the time of unpacking of a glass plate packing box, a holding member is hold | maintained with the holding member with which a box body is provided, and a glass plate pressing member is removed upward from a support | pillar simultaneously with the removal operation | work of a box body.

  In Patent Document 2, the presser member has a structure in which a side frame and a rear frame are integrated with a front frame that presses the front surface of the glass plate laminate so that the presser member can be detachably attached to the support column. For this reason, the pressing member requires a side frame and a rear frame in addition to the front frame that originally functions as a pressing member, and the weight increases accordingly. In addition, since the presser member is structured to be connected only to the support column erected on the rear side of the base part, the side frame and the rear frame need to be rigid enough to support the front frame, which increases the weight. Becomes more prominent.

  Therefore, even if the box and the presser member are removed at the same time during the unpacking operation to increase the work efficiency of the unpacking operation, the packing work and the unpacking operation of the glass plate laminate must be performed efficiently by increasing the weight of the presser member. There is a problem that is still difficult.

  In addition, when the weight of the glass plate packaging box itself increases, the number of glass substrates that can be stacked is inevitably reduced due to the relationship with the transportable weight of the transportation means, leading to deterioration in transportation efficiency.

  In view of the above circumstances, an object of the present invention is to provide a glass plate packaging box capable of efficiently performing packaging and unpacking operations of a glass plate laminate while reducing weight.

  In order to solve the above problems, the present invention provides a base portion on which a glass plate laminate in which a plurality of glass plates are laminated in a vertical posture is placed, and the glass plate laminate on the base portion. A bottom support portion that supports the bottom side of the glass plate laminate, a back support portion that supports the back surface of the glass plate laminate on the base portion, and a pressing member that presses the front surface of the glass plate laminate toward the back support portion side. And a glass plate packaging box that is removably held on the base portion and covers the glass plate laminate, and has a box that is open at the bottom, wherein both end portions of the pressing member are on both inner surfaces of the box Characterized by being attached to.

  According to such a configuration, both end portions of the pressing member are attached to both inner side surfaces of the box. Therefore, members corresponding to the side frame and the rear frame can be omitted as in the case where the presser member is attached to the pillars erected at both corners behind the base portion. Therefore, it is possible to reduce the weight of the pressing member itself, and it is possible to efficiently perform the packing operation and the unpacking operation of the glass plate laminate. Further, since the box itself is given a certain degree of rigidity in advance due to the box-like shape, it is not necessary to newly increase the rigidity excessively in order to attach the pressing member. Therefore, since the weight reduction as the whole glass plate packaging box can be achieved, it becomes possible to secure a sufficient number of laminated glass plates. Furthermore, since the pressing member is attached to both inner side surfaces of the box body, when the box body is pulled up and removed by a robot or the like, the pressing member is also removed together with the box body. Due to the synergistic effect, the work efficiency of the unpacking work is further improved.

  In said structure, the said box can be divided | segmented into two front and back, the front box which covers the front of the said glass plate laminated body, and the back box which covers the both sides of the said glass plate laminated body, back, and the upper direction. It is preferable that both end portions of the pressing member are attached to both inner side surfaces of the rear box.

  In this way, the both side surfaces of the rear box to which the pressing member is attached are integrated with the rear surface of the rear box and the upper surface being reinforced by the upper surface, so that the pressing member can be held more securely. .

  Said structure WHEREIN: It is preferable that the said pressing member is provided with the cushion material which expands-contracts at least in the front-back direction and provides a pressing force to the said glass plate laminated body.

  In this way, the pressing force by the pressing member can be applied uniformly to the surface of the glass plate laminate via the cushion material, so that stress concentrates on a part of the glass plate laminate and the glass plate The situation where breakage occurs can be reduced as much as possible. In addition, if a board | plate material is separately arrange | positioned between a cushion material and a glass plate laminated body, it will become possible to make a uniform pressing force act in a wider range.

  Said structure WHEREIN: It is preferable that a part of said box is formed with the transparent material.

  If it does in this way, it will become possible to visually recognize the inside of a box via a part of box formed with a transparent material. Therefore, even if the glass plate laminate housed inside the glass plate packaging box is damaged, the situation can be recognized through a part of the box formed of a transparent material. The risk of contaminating the space with broken glass after removing the box in a space requiring cleanliness such as a clean room can be reduced as much as possible. The transparent material includes polymethyl methacrylate resin (PMMA), polycarbonate resin (PC), ABS resin, AS resin, polypropylene resin (PP), polyethylene terephthalate resin (PET), polystyrene resin (PS), polyvinyl chloride. Resin (PVC), Polymethylpentene resin (PMP), Polyarylate resin (PAR), Polyethersulfone resin (PES), Polyetherimide resin (PEI), Polyphenylene sulfide resin (PPS), Polyetheretherketone resin ( PEEK), synthetic organic resins such as polyimide resin (PI), or glass.

  Said structure WHEREIN: It is preferable that the said base support part is being fixed only to the said back surface support part in the state which formed the space | gap between the said base parts.

  In this way, even if the base plate portion is deformed when the glass plate packing box packed with the glass plate laminate is placed on the floor surface or lifted by a lift, the deformation is caused. Therefore, it is difficult to transmit the influence to the bottom support portion, so that it is possible to reliably prevent breakage starting from the bottom of the glass plate.

  Said structure WHEREIN: It is preferable that the glass support surface of the said back surface support part inclines back at 65 degrees-85 degrees with respect to the upper surface of the said base part.

  If it does in this way, it will become possible to pack a glass plate laminated body with the stable attitude | position.

  Said structure WHEREIN: It is preferable that the angle | corner which the glass support surface of the said back surface support part and the glass support surface of the said base support part make is 90 degrees-110 degrees.

  In this way, it is possible to prevent a situation in which the highest part of the upper side of the glass plate laminate is unduly high, so that a glass plate laminate in which more glass plates are laminated can be configured.

  As described above, according to the present invention, it is possible to provide a glass plate packaging box capable of efficiently performing the packing operation and the unpacking operation of the glass plate laminate while reducing the weight.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.
