Description

  The present invention is a glass substrate for glass, a glass substrate for liquid crystal display, a glass substrate for plasma display, a fluorescent display tube, a glass substrate for a thermal head, various glass substrates such as a color filter, or a finished panel manufactured using these glass substrates. The present invention relates to a plate-shaped body transport box used for transporting or storing such a plate-shaped body.

  In recent years, glass substrates used for incorporating semiconductor devices and the like have become larger and thinner. Such a glass substrate is easily damaged by an impact during transportation. Therefore, as a transport box used when transporting a glass substrate or the like, as described in Patent Documents 1, 2, etc., transport comprising a container body made of a synthetic resin foam having a cushioning property and a lid body A box has been proposed.

  In general, this type of transport box has vertical grooves formed at regular intervals on one opposing side wall on the container body side, and at the bottom surface and the top surface of the lid. A lateral groove is formed at a corresponding position. Then, after storing the required number of glass substrates in the vertical direction and without contacting each other with the left and right side edges and the lower edge inserted in the vertical and horizontal grooves formed on the container body side, the lid The member is attached to the opening side of the container body.

  As described above, in a conventional box for transporting glass substrates, a plurality of glass substrates are accommodated in a container body in a vertical orientation, and then a lid is applied from above. When the size of the glass substrate to be transported is relatively small and the number of sheets to be accommodated in the transport box is relatively small, the lateral groove formed on the top surface of the lid with the upper edge of the glass substrate accommodated in the container body The lid can be easily put in a state where it is securely inserted.

  However, in recent years, it has been expected that the glass substrate becomes larger and that the number of sheets accommodated in one transport box is increased in order to obtain high transport efficiency. The interval between the concave grooves for accommodation tends to be narrower than the conventional one.

  In that case, it becomes difficult to insert the upper edge of each glass substrate accommodated in the container body into each lateral groove formed on the top surface of the lid, and it takes a lot of time to close the lid, It may happen that the lid is capped while a part of the lateral groove formed on the top surface of the lid is crushed. In the latter case, glass substrates adjacent to each other may be in direct contact with each other due to vibration during conveyance, and must be avoided.

  The present invention has been made in view of the circumstances as described above, and each glass accommodated in a container main body in each lateral groove formed on the top surface of the lid, even when the transport box is enlarged. For transporting plate-like bodies that can easily and reliably insert the upper edge of the substrate, thereby reliably preventing contact between plate-like bodies such as glass substrates accommodated during transportation. The challenge is to provide a box.

  The plate-like body transport box according to the present invention includes a container body in which a plurality of vertical grooves for inserting and supporting the left and right side edges of the plate-like body are formed at a constant pitch on at least one opposite side wall. A plate-shaped body made of a synthetic resin foam comprising a lid body in which a plurality of lateral grooves for inserting and supporting the upper edge of the plate-shaped body housed in the container body are formed at a constant pitch on the top surface portion. The box is characterized in that the lid body is composed of a first lid member and a second lid member that are divided into two in a direction intersecting the transverse groove.

  In the above plate-like body transport box, when the lid is put on the upper edge side of the plate-like body housed in a state where the both side edges are inserted and supported in the vertical groove formed in the container body, Then, cover one of the two divided lid members. The divided lid member has a cross-section of the transverse groove formed on the top surface on its divided surface, and the operator positions the upper edge so that the upper edge of each plate-like body enters within each cross-section. While finely adjusting, one of the lid members can be easily put on as intended, that is, without crushing the wall between the lateral grooves.

  By covering one lid member, the plate member is in a state where the upper edge is firmly positioned in addition to both side edges, so that the operator can crush the wall between the lateral grooves even when covering the other lid member. Therefore, the covering work can be performed in a state where the upper edge of each plate-like body is securely inserted into each lateral groove.

  In a preferred embodiment of the plate-like body transporting box according to the present invention, a concave portion is formed on the upper surface of one of the first lid member and the second lid member, and the convex portion that can enter the concave portion is formed on the other. The parts are integrally formed.

  In this aspect, since the lid body is tightened in a state where the convex portion formed in the other lid member enters the concave portion formed in one lid member, between the divided lid members due to vibration during transportation or the like. It is possible to reliably prevent the occurrence of displacement.

  In a preferred embodiment of the plate-like body transport box according to the present invention, the container body and the lid body are configured such that the lower edge side of the lid body is fitted into the upper edge side of the container body.

  In this aspect, since the lower edge portion of the lid body is fitted into the upper edge side of the container body, each divided lid member is unexpectedly separated from the container body even though the lid body is divided into two. Can be reliably prevented from coming off. In the case where the lid has a concave portion formed on one upper surface and a convex portion that can enter the concave portion is integrally formed on the other side, the lid body is unexpectedly formed during transportation or the like. It can prevent more reliably that it comes off.

  Preferably, the container main body and the lid constituting the synthetic resin foam-made plate-like body transport box according to the present invention are molded by in-mold molding of foamable particles of thermoplastic resin. More preferably, as the expandable particles, expandable composite resin particles containing a styrene resin and an olefin resin are used. A composite resin containing a styrene resin and an olefin resin is obtained by impregnating and polymerizing a polyolefin resin particle with a styrene monomer. Among the composite resins of a styrene resin and an olefin resin, a styrene resin is obtained. A composite resin of a resin and an ethylene-based resin is preferable. For example, the ratio of the styrene component is 40 to 90% by weight, preferably 50 to 85%, more preferably 55 to 75% by weight, and the magnification of the foam is 3 to 60. Double is preferred. A molded article made of expandable composite resin particles containing a styrene resin and an olefin resin is stronger than a polypropylene resin foam molded article having the same expansion ratio and has a small shrinkage ratio and good dimensional accuracy. Therefore, there is little variation in dimensions. Furthermore, there is an advantage that dust due to friction or the like is difficult to be produced as compared with a polystyrene resin foam molded product.

  According to the present invention, the upper edge of each glass substrate housed in the container body is easily and surely inserted into each lateral groove formed on the top surface of the lid even when the transport box is enlarged. Thus, it is possible to obtain a plate-like body transport box that can reliably prevent the plate-like bodies such as glass substrates accommodated during transportation from coming into contact with each other.

  DESCRIPTION OF EMBODIMENTS Hereinafter, a plate-like body transport box according to the present invention will be described based on embodiments with reference to the accompanying drawings. As shown in FIG. 1, the plate-like body transport box 1 includes a container body 10 and a lid body 30 that covers the container body 10. In this example, the container body 10 and the lid body 30 are both formed by in-mold foam molding of foamable composite resin particles containing a styrene resin and an olefin resin.

  The container main body 10 has a shape in which an upper part composed of four side walls and a bottom surface is opened, and in this example, the horizontal cross section is rectangular. The container body 10 includes front and rear side walls 11 and 12 that face each other, and four side walls that are left and right side walls 13 and 14 that face each other, and a bottom surface 15. A plurality of vertical grooves 20 for inserting and supporting the left and right side edges of the plate-like body accommodated in the container body 10 are formed on the left and right side walls 13 and 14 facing each other at a constant pitch.

  Although not essential, the container body 10 shown in the figure has the lateral groove 21 constant so that the bottom surface 15 is positioned in a virtual vertical plane including the longitudinal grooves 20 and 20 formed in the left and right side walls 13 and 14. It is formed with a pitch. As shown in the cross-sectional view of FIG. 2, the lateral groove 21 is discontinuous in the longitudinal direction of the groove, and a portion without the groove is a recess 22. An appropriate elastic material 23 can be embedded in some of the recesses 22. In the figure, reference numeral 22a denotes a positioning projection of the elastic material 23.

  The inner peripheral surface of the four circumferences on the upper edge side of the container body 10 is an inner stepped portion 24 that is cut out to the required depth on the inner side, and the vertical groove 20 is formed on the stepped surface of the inner stepped portion 24 from the bottom surface 15. It is formed to reach the vicinity of 25. In the figure, reference numeral 26 denotes a recess that functions as a handle when the container body 10 is held.

  The lid 30 has a shape that can close the upper opening of the container body 10, and includes four side walls 31, 32, 33, 34 and a top plate 35, and the first lid member 50 as a whole. It consists of two members, the second lid member 60. Further, lateral grooves 36 are formed on the back surface of the top plate 35 at a constant pitch so as to be positioned in a virtual vertical plane including the vertical grooves 20 formed on the left and right side walls 13 and 14 of the container body 10. . In this example, the lid 30 is divided into two by a dividing plane perpendicular to the direction perpendicular to the transverse groove 36 at a substantially central position in the direction in which the transverse groove 36 runs, whereby the first lid member on the left side in the figure. 50 and the second lid member 60 on the right side. In addition, it is not essential that the division position is the center position, and the position may be deviated to one side. The dividing surface may be an inclined surface instead of a vertical surface.

  On the surface side of the top plate 35 in the vicinity of the dividing surface of the first lid member 50, a concave groove 51 is formed in parallel with the dividing surface. On the other hand, an extension 61 of the top plate 35 is integrally formed on the side of the split surface of the second lid member 60, and the first lid member 50 and the second lid member 60 are divided into split surfaces as shown in the figure. When the top plate extension 61 is positioned in the concave groove 51 of the first lid member 50 when they are positioned in close contact with each other, a convex portion having a size that fits into the concave groove 51. 62 is formed downward.

  Further, on the lower surface side of the four side walls 31, 32, 33, 34 of the lid body 30, an inner side wall 37 having a shape that fits inside the inner stepped portion 24 formed on the four circumferences on the upper edge side of the container body 10, and Has been.

  The lateral groove 36 formed on the back surface of the top plate 35 may be formed on the entire back surface of the top plate 35, but in the illustrated example, the longitudinal direction of the groove is the same as the lateral groove 21 formed on the bottom surface 15 of the container body 10. The portion without the groove is a recess 39. An appropriate elastic material 23 similar to that embedded in the recess 22 can be embedded in some of the recesses 39. In the figure, 39a is a positioning protrusion of the elastic material 23.

  A prism 63 having a height that does not reach the outer surface of the side wall 32 is formed in a vertical direction at an appropriate position on the inner side wall 37 of one lid member, in this example, the second lid member 60. In addition, a concave portion 40 for stealing meat is formed on the top surface of the top plate 35 of the lid body 30, and work for removing the lid body 30 is performed at an appropriate position on the lower edge side of the side walls 31, 32, 33, 34. In order to facilitate, a suitable number of notches 41 are formed.

  As shown in FIG. 1, when the container body 10 is covered with the second lid member 60, the wall surface of the inner stepped portion 24 of the side wall 12 where the prism 63 formed on the second lid member 60 is located. A vertical cutout groove 27 into which the prism 63 can enter is formed. Further, as shown in FIG. 2, an appropriate number of ridges 28 extending in the horizontal direction are formed on the vertical wall portion of the inner stepped portion 24 of the side walls 11 to 14 at an appropriate interval.

  When packing a plate-like body such as a glass substrate in the plate-like body transport box 1 described above, first, some of the recesses 22 formed in the bottom surface 15 of the container body 10 (in the illustrated example, FIG. The cushioning material 23 is attached to two places in the center as shown in FIG. Next, the plate-like body suspended by a robot hand or the like is dropped from the opening side of the container body 10 so that both side edges of the plate-like body enter the left and right vertical grooves 20 and 20. The plate-like body is guided by the left and right vertical grooves 20, 20 and gradually falls, and stops at a position where the lower edge enters the horizontal groove 21 formed in the bottom surface 15 of the container body 10. Is housed in a stable posture. Similarly, the necessary number of plate-like bodies are accommodated in the container body 10 in the same manner.

  After the required number of plate-like bodies are accommodated in the container body 10, the lid body 30 is put on. At this time, as in the case of the container body 10, some of the recesses 39 formed in the back surface of the top plate 35 of the lid body 10 (in the illustrated example, the first lid member 50 and the second lid member 60. The cushioning material 23 is attached to each one of the above.

  First, the first lid member 50 is covered. When covering, the operator can see the horizontal grooves 36 formed in the first lid member 50 from the divided surface side, so that the upper side of the plate-like body accommodated in the container main body 10 in each horizontal groove 36 can be seen. The first lid member 50 can be covered while adjusting the posture of the upper edge of the plate-like body so that the edge enters the corresponding lateral groove 36. In the process, the inner wall 37 of the first lid member 50 enters the inner stepped portion 24 of the container body 10 in an internally fitted state, and the bottom surface of the inner wall 37 is the stepped portion of the inner stepped portion 24. The state is in contact with the surface 25. In this posture, the ridge 28 formed on the inner step portion 24 of the container body 10 deforms the inner wall 37 of the first lid member 50 and enters the inner wall 37. Thereby, the upward movement of the first lid member 50 is restricted.

  Next, the second lid member 60 is put on. At this time, the accommodated plate-like body is in a state where the upper edge side is inserted into the lateral groove 36 formed in the first lid member 50, and the required positioning is performed. Therefore, by dropping the second lid member 60 from above, the upper edge side of the accommodated plate-like body surely enters the lateral groove 36 formed on the back surface thereof. Finally, as shown in FIG. 2, as in the case of the first lid member 50, the ridge 28 formed on the inner stepped portion 24 of the container body 10 deforms the inner side wall 37 to change the inner side. By entering the wall 37, the upward movement of the second lid member 60 is restricted. Further, in this state, the convex portion 62 of the top plate extension 61 formed on the second lid member 60 is in a posture of entering the concave groove 51 formed on the top plate 35 of the first lid member 50. Therefore, it is possible to reliably prevent the first lid member 50 and the second lid member 60 from moving irregularly in the lateral direction.

  Further, when the first lid member 50 and the second lid member 60 are attached at the correct positions, the prisms 63 formed on the inner wall 37 of the second lid member 60 are formed on the side wall 12 of the container body 10. It can enter into a longitudinal cutout groove 27 formed in the inner stepped portion 24. However, in this example, when the second lid member 60 is set to the left side and the first lid member 50 is set to the right side to be attached to the container main body 10, the prism 63 becomes an obstacle and the lid cannot be closed. Thereby, it can prevent reliably covering the 1st cover member 50 and the 2nd cover member 60 in a wrong position.
