Description

  The present invention is for transporting plate-like bodies used for transporting and storing various glass substrates such as glass plates, liquid crystal display and plasma display glass substrates, touch sensors, touch panels, and other plate-like bodies. It relates to the container.

  Conventionally, as a transport container for storing and transporting a plate-like glass, a relatively large glass substrate such as a glass substrate for liquid crystal display, or a panel such as a solar battery panel or other impact-sensitive plate-like body, it is buffered. One plate-like body is formed in a longitudinal groove arranged at equal intervals on the inner surface of one opposite side wall of the container body. In general, those inserted one by one and supported in an upright state so as not to contact each other are stored.

  In recent years, due to an increase in demand for large-sized liquid crystal televisions and plasma televisions, large-sized glass substrates in which one or both of the vertical and horizontal directions exceed 100 cm have been adopted as glass substrates for televisions. Transport containers for transport are also becoming larger.

  However, in the conventional method of accommodating the glass substrate in an upright state by the vertical groove on the inner surface of the side wall, the glass substrate itself is bent and deformed by its own weight because of the large and heavy glass substrate, or the weight of the glass substrate is a container. When the load is concentrated on the bottom of the main body, the bottom of the container is compressed and deformed, and the cushion function and the impact relaxation function may be impaired.

  In order not to cause such a problem, as illustrated in Patent Documents 1 and 2, glass substrates and protective sheets are alternately stacked and stored in a horizontal state in a container body, and each glass substrate is protected. A container for conveyance which has been received by a surface via a sheet has also appeared. In particular, in the case of a plate-like body such as an expensive panel, containers each containing a plate-like body are stacked and banded and packed. These containers for transportation do not have the risk of breakage or cracking due to the bending deformation of the glass substrate, and can favorably protect plate-like bodies such as panels.

  By the way, depending on the type of a plate-like body such as this type of panel, the contactable portion capable of receiving a supporting load is opposed to one side of the square plate-like body, for example, the entire length of the end face on one side of the front side, and the front side. There are cases where only the left and right end corners of the rear side, and the end surfaces and front and back surfaces of the other side cannot be contacted.

  However, in the case of Patent Documents 1 and 2, a special plate-like body in which each of the four sides of the plate-like body to be accommodated can abut against the inner surface of the container and the contactable portion is specified as described above. The protection at the time of transport is not taken into consideration, and further improvement of the plate-like body as a transport container is desired.

JP 2004-59116 A JP-A-2005-75366

  In the present invention, in view of the above, the contactable part that can receive the supporting load at the end face is only the end face full length of one side of the quadrangular plate-like body and the corner parts at both ends on the side opposite to the side. A plate-like body that can stably support the plate-like body at the end face on one side that can contact the plate-like body, and can also be supported at both end corners on the side opposite to the one side The container for conveyance is provided.

  The plate-shaped transport container of the present invention that solves the above problems is a flat rectangular transport container having a storage recess for storing a rectangular plate-shaped body in a flat state, wherein the storage recess is a peripheral edge of the main body. A plate-like body that is recessed with a frame portion for stacking in the part and that can contact only the entire length of one end face is formed so that it can be accommodated with clearance around each side. An inclined surface that is inclined downward toward the side corresponding to the one side of the plate-like body in which the bottom upper surface of the concave portion is housed is formed.

  This transport container is stored when a plate-like body with which the entire end face of one side can be contacted is stored in the storage recess and placed on the upper surface of the bottom so that the one side is positioned on the lower side of the upper surface of the bottom forming an inclined surface. The plate-like body is positioned so as to be shifted to the lower side of the slope of the top surface of the bottom due to its own weight, vibration, etc., and is supported in contact with the inner surface of the frame portion with the entire length of the end surface of the one side that can be contacted. Thus, the end face of each side that cannot be contacted can be supported without contacting the inner surface of the frame portion.

  In the container for transporting the plate-like body, the opposite corners of the plate-like body to be stored on the inner side surface of the frame portion are provided at the corners at both ends of the upper side portion of the bottom surface of the inclined bottom portion of the storage recess. It is preferable to form a slanted side portion for restricting the position where the corner portions on both sides abut.

  That is, the opposite corners of the opposite side of the stored plate-like body that come into contact with each other are positioned by abutting on the oblique side portion, and the plate-like body is positioned between the one side and the side. It will be possible to support with good stability at the two corners on both sides of the opposite side, and the displacement of the plate-like body in the opposite-side direction with respect to the one side and the displacement in the both-side direction can be regulated. Rotation can also be restricted, and there is no fear that most of the end surfaces of each side that cannot be contacted other than the one side of the plate-like body are brought into contact with the inner surface of the frame portion.

  In the container for transporting the plate-like body, the stepped shape in which both end faces of the plate-like body are in contact with the inner side surfaces of the side portions at both end corner portions of the upper side portion of the inclined upper surface of the bottom portion of the storage recess. An oblique side for regulating the position where both end corners of the side opposite to the one side of the plate-like body to be stored abuts is formed on the higher side from the convex. It can be formed continuously on the inner surface of the frame. In this case, the end surfaces of the left and right sides of both corners of the opposite side of the one side are in contact with the stepped side portions, so that the displacement of the plate-like body in the left and right side directions can be restricted, and the end surfaces of both sides And no contact with the inner surface of the frame of the storage recess.

  In the plate-like transport container, a concave portion is provided on the upper surface of the inclined bottom portion of the storage concave portion along the inner side of the frame portion of each of the other side portions excluding the lower side portion. be able to. In this case, it is possible to prevent the front and back surfaces of each side excluding the one side of the plate-like body from coming into contact with the top surface of the bottom portion, and the protection of each side portion can be further improved.

  In the plate-like container, the lower surface of the peripheral edge of the main body is provided with notches that can be fitted to the frame of the lower container when stacked, and the four corners of the peripheral edge of the main body in the notch The mounting leg portion is provided at a required location including the above, and the upper surface of the frame portion is provided with a concave portion into which the leg portion of the upper container is fitted during stacking.

  As described above, according to the container for transporting a plate-like body of the present invention, a plate-like body such as a glass substrate to be transported can be contacted with the entire length of the end surface by utilizing the inclination of the upper surface of the bottom of the storage recess. It is possible to support with good stability so that the side is positioned on the inner surface of the frame portion that defines the storage recess. In particular, in the case where oblique side portions are provided on the inner surface of the frame portion at both end corner portions of the upper side portion of the slope of the upper surface of the bottom portion, both end corner portions on the side facing the one side of the plate-like body are By abutting on the shape side portion, the stored plate-like body can be supported with good stability in a state where the other end portion has a clearance at the full length of the end surface of the one side and the two corner portions.

  Next, embodiments of the present invention will be described based on examples shown in the drawings.

  FIGS. 1-7 has shown one Example of the container for conveyance of the plate-shaped object concerning this invention. The transport container A of this embodiment has a storage recess 1 that is recessed at the periphery of the main body leaving a frame portion 2 for stacking, and is at least one plate-like object such as a glass substrate or panel to be transported. It is a flat rectangular container formed so that the body B can be stored in a flat state.

  The storage recess 1 is formed to be slightly larger than the plate-like body B to be transported. For example, the entire length of the end surface of the front side b1 that is one side of a quadrangle and both ends on the rear side that are opposite sides of the front side b1 In the case where the corners b2 and b2 are in contact with each other, that is, a plate-like body B capable of receiving a supporting load, it can be accommodated with a predetermined clearance around each side, for example, a clearance of several mm. It has become.

  In the present invention, the upper surface 3a of the bottom 3 of the storage recess 1 faces the front side 11 so that the side of the front side 11 corresponding to the front side b1 of the plate-like body B to be stored becomes lower. It has a downward slope. As a result, the stored plate-like body B is likely to be shifted to the lower side of the bottom upper surface 3a inclined due to its own weight, vibration during transportation, and the like, and the front side b1 of the plate-like body B is placed inside the frame portion 2. It can be supported with good stability in a state where it is in contact with the side surface.

  The left and right end corners of the rear side 12 that are the higher side of the inclined bottom upper surface 3a in the storage recess 3 are connected to the front side b1 of the plate-like body B stored on the inner surface of the frame 2. Diagonal side portions (side portions that are oblique with respect to the vertical and horizontal directions) 4 and 4 for restricting the position where the opposite end corner portions b2 and b2 on the rear side, which are opposite sides, come into contact with each other are formed. Since both end corners b2 and b2 on the rear side of the plate-like body B are in contact with the oblique sides 4 and 4, displacement in the rear and left and right directions can be regulated. Normally, the both end corners b2 and b2 are inclined to the inclined side parts 4 and 4 in a state where the front side b1 is in contact with or close to the inner side surface of the frame part 2 of the front side part 11 due to the inclination of the upper surface 3a of the bottom part 3. By abutting or approaching, the position can be supported and supported by the entire length of the end surface of the front side b1 and the two corners b2 and b2.

  In the case shown in the figure, the both end surfaces of the plate-like body B are in contact with the inner side surfaces of the side sides 13 and 13 at both corners of the rear side portion 12 of the upper side of the inclined bottom surface 3a in the storage recess 1. The side portions 5 and 5 are formed, and the inclined side portions 4 and 4 are continuously formed from the stepped side portions 5 and 5 to the inner surface of the frame portion 2 of the side portion 12 on the higher side. Thus, the lateral displacement of the plate-like body B can be restricted by the stepped side portions 5 and 5, and the backward displacement can be restricted by the oblique side portions 4 and 4. In the state where the front side b1 of the plate-like body B is in contact with the inner side surface of the frame part of the front side part 11, the stepped side parts 5 and 5 are in contact with the side end surfaces of the rear side corner parts b2 and b2. It is formed at a position where it can touch.

  With the above configuration, when the plate-like body B housed in the housing recess 1 is displaced to the lower side (front side) of the bottom surface 3a, or when displaced in the left-right direction, FIG. The total length of the end surface of the front side b1 that can be contacted is in contact with the inner surface of the frame part 2, or both end corners b2 and b2 on the rear side are in contact with the oblique side part 4 and the stepped side part 5. Can be supported with the clearance held on the side sides, and when the plate-like body B is displaced rearward as shown in FIG. 7B, both end corners b2 and b2 on the rear side are inclined sides. 4, the clearance can be supported by supporting the rear side portion, and when the plate-like body B is about to rotate, the front side b1 is a frame on the front side portion 11 side as shown in FIG. Further contact with the inner side surface of the portion 2 and one corner portion b2 on the rear side abuts on the oblique side portion 4, thereby further rotation. It would be supported so as to regulate. In particular, the size (vertical and horizontal dimensions) of the plate-like body B to be accommodated can cope with a slight change due to the effect of the oblique sides 4.

  In the transport container A, the upper surface 3a of the bottom 3 of the storage recess 1 has a very shallow recess 6 along the inside of the frame 2 of each of the other side portions 12 and 13, excluding the lower side portion 11. It is provided so that the back surface of each side other than the front side b1 of the stored plate-like body B can be prevented from contacting the bottom surface 3a. In the case of the figure, a similar concave portion 10 is also provided on the lower surface of the bottom portion 3 at a position corresponding to the concave portion 6 so that the surface of each side of the plate-like body B can be prevented from contacting.

  The transfer container A is provided with a notch 7 on the outer peripheral part on the lower surface side in which the frame 2 of the lower container A can be fitted when stacked, and the frame 2 is formed in the notch 7. By fitting, the lower part of the bottom 3 of the storage recess 1 is provided so as to fit into the storage recess 1 of the lower container A. In this fitted state, a plate-like body is placed on the bottom 3 of the storage recess 1. It is formed so that the storage space for B can be secured. In particular, the bottom surface 3b of the bottom portion 3 has an inclined surface corresponding to the top surface, and the bottom portion top surface 3a of the bottom container A and the top container in a state where the bottom portion 3 is fitted and stacked in the storage recess 1 of the bottom container A, A gap S necessary for storing the plate-like body B is formed between the bottom surface 3b of A and the bottom surface 3b. Normally, the gap S does not apply a stacking load to one plate B, particularly a plate B in a state where a protective sheet (not shown) such as a film or paper is overlapped and protected on the front and back surfaces. In this way, the plate-like body B can be stored and held, and the plate-like body B can be prevented from being lifted excessively.

  The transfer container A is approximately the same as the lowest position on the lower surface of the bottom 3 of the storage recess 1 in the vicinity of the four corners and / or the side of the cutout 7 so that it can be placed horizontally on a horizontal plane. A leg portion 8 protruding slightly downward is projected, and a concave portion 9 in which the leg portion 8 is fitted is provided on the upper surface side of the frame portion 2 in a stacked state where the frame portions 2 are in contact with each other. ing.

  The step-like side portions 5 and 5 can be applied to the case where the end surfaces on the side sides can be contacted and supported at the left and right end corner portions of the rear side of the plate-like body B to be stored. When the end face abutment on the rear side of the both corners can be supported, the stepped side is provided on the side of the rear side, and the slanted side between the stepped side and both sides It can also be implemented.

  In addition, when the both end corners on the rear side cannot contact both the end faces on both sides and the rear side, as shown in FIG. 8, the rear end is set so that only the ends of the opposite end corners are in contact with each other. It can also be carried out by providing the oblique side 4 between the side 12 and the side 13. Other configurations are the same as those in the above-described embodiment. Also in this case, as shown by a chain line in FIG. 9, the front side b1 and the both end corners b2 and b2 on the rear side with respect to displacement and rotation in the front-rear direction and the left-right direction of the stored plate-like body B, By contacting the oblique side portions 4 and 4 of the corner portion on the inner surface and the rear side of the frame portion of the front side portion 11, the predetermined clearance can be maintained and supported.

  Constituent materials for the transport container 1 include polystyrene, high impact polystyrene, styrene-ethylene copolymer, styrene-maleic anhydride copolymer, styrene-acrylonitrile copolymer, and other polystyrene resins, polyethylene, polypropylene, and ethylene. -Foams of various synthetic resins such as polyolefin resins such as vinyl acetate copolymer and polyester resins such as polylactic acid and polyethylene terephthalate can be used. Especially, the molded object by the bead foam of the composite resin containing a polystyrene-type resin and a polyolefin-type resin is used suitably. A composite resin bead foam containing a polystyrene resin and a polyolefin resin is obtained by polymerizing a polyolefin resin particle with a styrene monomer and then steam-heating the expandable resin particles impregnated with a foaming agent. A molded body can be obtained.

  The above-described transport container A is, for example, a plate-like body B such as a glass substrate or a panel, which is protected by sticking a protective sheet such as a film or paper on the front and back surfaces, and the front side b1 side where the entire end face can be contacted. It is housed in the housing recess 1 so as to be positioned on the lower side of the bottom top surface 3a that forms an inclined surface, and is placed on the bottom 3 with a clearance around it. At this time, the plate-like body B to be accommodated is easily located near the bottom surface 3a that forms an inclined surface, and the front side b1 is on the lower side, that is, the inner surface of the frame 2 of the front side 11, and both ends on the rear side. The corner portions b2 and b2 are held in contact with or close to the oblique side portion 4 provided on the inner surface of the frame portion 2 at the corner portion of the rear side portion 12.

  In this way, they are stacked as shown in FIG. 5, and the whole is belted (not shown) or wrapped in an outer box for transportation or the like.

  In this conveyance, displacement or the like in the front side or the rear side, which is the lower side of the bottom upper surface 3a where the plate-like body B in the storage recess 1 is inclined due to vibration or the like, displacement in the left-right direction, and With respect to the rotation, as shown by the chain lines in FIGS. 7A, 7B and 7C and FIG. 9, the clearance can be supported with securing a clearance on the peripheral side portion excluding the front side b1 where the entire end face can be contacted. Therefore, the plate-like body B to be accommodated can be stably held so as to restrict the movement at the front side b1 where the entire length of the end surface can be contacted and the both end corners b2 and b2 on the rear side facing the side. Further, it is possible to prevent the plate-like body B from being damaged and to protect the plate-like body B satisfactorily. Furthermore, the form of the inclined side portion 4 is utilized. By restricting front / rear / left / right displacement, it is also possible to apply to a slight size difference of the plate-like body.

  The transport container of the present invention transports various plate-like bodies such as a base plate glass, a relatively large glass substrate such as a glass substrate for liquid crystal display or plasma display, or a panel sensitive to impact such as a touch sensor or a touch panel. It can be suitably used for storage.
