Description

  The present invention relates to a plate-like container for transporting and storing various glass substrates such as glass plates for glass, liquid crystal displays and plasma displays, and other plate-like bodies. .

  Conventionally, as a transport container for storing and transporting relatively large glass substrates such as glass plates for glass, liquid crystal displays, etc., or panels such as solar cell panels and touch panels, and other impact-sensitive plates. A container body made of a synthetic resin foam having a cushioning property and a lid body, and the plate-like body is placed in a longitudinal groove arranged in parallel 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 and stored in an upright state so as not to contact each other have been used.

  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, the glass substrate and the protective sheet are alternately stacked and stored in a horizontal state in the container body, and each glass substrate is received by the surface through the protective sheet. Containers have also appeared.

  As described above, in the case of a transport container that stores a plate-like body such as a glass substrate in a horizontal state, the corner of the stored plate-like body is easily affected by vibration or impact during transportation, Damage may occur due to contact with the inner surface of the side wall.

  For this reason, for example, in Patent Document 1, in the glass substrate transport box, the corner portion of the glass substrate to be stored is prevented from coming into contact with the corner portion of the box body in order to protect the glass substrate to be stored. As described above, by forming notch spaces at the four corners of the main body and forming concave grooves at intervals on the inner surface of the side wall of the main body, each side of the peripheral edge of the glass substrate extends over the entire length of the side wall. To avoid contact.

  However, the container body is made of a synthetic resin foam such as expanded polystyrene, and it is against the bending deformation of the plate-like body and the container itself due to the vertical vibration in the transportation and carrying work or the drop impact from the bottom side corner. There are places where we cannot be satisfied with the protection of the corners.

  For example, as shown in FIG. 12, when the cutout spaces 116 are formed at the four corners of the container body 101, the corners b of the stored plate-like body B are positioned at the opening portions on the storage portion side of the cutout spaces 116. However, when falling from the corner of the container, a strong force is locally applied to the side wall 114 in the vicinity of the corner of the container body 101 made of the synthetic resin foam due to the load of the plate-like body B itself. The corner portion b of the plate-like body B enters the notch space 116 (two-dot chain line), and the corner portion b may finally come into contact with the inner surface of the notch space 116. . In such a case, there is a possibility that the corner portion b is damaged, or the inner surface of the notch space 116 is cracked to cause cracking.

  Further, as in Patent Document 2, in order to protect the corner portion of the plate-like body to be stored, a reinforcing material having a cushioning property is disposed at the corner portion of the storage portion to prevent excessive deformation of the side wall. Some of them protect the corners of the body.

  However, in the case of the above proposal, the reinforcing member is arranged so as to be flush with the inner surface of the side wall, so that the edge of the plate-like body comes into contact with the inner surface of the side wall, and There is a risk of damage to the corners of the plate or the corners of the container body when the corners are dropped because the corners are not provided with notched spaces that allow the corners of the plates to escape. There is.

  The present invention has been made in order to solve the above-mentioned problems, and is a container for transporting a plate-shaped body for storing and transporting a plate-shaped body such as a glass substrate, a solar battery panel, and a touch panel in a flat state. As a result, the peripheral edge of the stored plate-like body can be well protected, and the container body side wall, particularly in the vicinity of the corner due to vibration or drop impact during transportation or transportation work, especially falling from the container corner Effective reinforcement is applied when a strong force is applied to the side wall of the metal plate, and the side wall is bent and the corner portion of the plate-like body is prevented from coming into contact with the inner surface of the notch space, and is also well protected when contacted temporarily. Further, the present invention provides a container for transporting a plate-like body that is excellent in durability and durability.

The plate-shaped conveyance container of the present invention that solves the above-mentioned problems has a flat rectangular container body that is formed of a synthetic resin foam and opens upward, and one or more plate-shaped objects are flattened. A container for storing and transporting the container in a placed state, wherein four corners on the inner surface of the side wall of the storage portion of the container body are provided with notch spaces for corner relief extended from the inner surface of the side wall. along the inner surface of the space to the inner surface of the corner portion near the region over the inner surface of the side wall of the aspect, Ri Na and reinforcements in from the container body rigidity is mounted, said reinforcements projecting from the inner surface of the side wall by the thickness of It is characterized by.

  The container for transportation includes a case where a plurality of plate-like bodies are stacked in a container body and stored in a flat state, and a cover body is attached and packaged. There are cases in which the objects are stored in a flat state and stacked and packaged without a lid.

  According to the transport container, at the corner in the storage section, the container extends along the inner surface of the area near the corner including the notch space, that is, the inner surface of the portion extending from the inner surface of the notch space to the inner surfaces of the vertical and lateral side walls. Since a stiffer reinforcing material is attached than the main body, the plate-like body housed in the housing part and placed on the bottom part comes into contact with the reinforcing material in the vertical and horizontal edges, and the edge is There is no direct contact with the inner surface of the side wall. Moreover, when a load of a relatively heavy plate-like body acts on the side wall during a drop impact during transportation or transportation, particularly when the corner falls, it is attached to the inner surface of the area near the corner. By receiving the load by the reinforcing material, for example, local excessive bending deformation in the vicinity of the notch space can be suppressed, so that the corner portion of the plate-like body can be prevented from coming into contact with the inner surface of the notch space. Further, even if the corner portion of the plate-like body comes into contact with the inner surface of the notch space, it is not easily damaged.

  In the container for transporting a plate-like body, the reinforcing material is provided at a lower end of the reinforcing material in a slit formed in a bottom portion along an inner surface and an inner surface of the side wall of the notch portion in the vicinity of the corner portion of the container body. It is preferable that the part is detachably fitted by being elastically inserted. In this case, it is easy to detach and attach a reinforcing material that is a separate material and a separate member from the container body, and it is also easy to separate the reinforcing material that is a separate material when the container body is recycled and used after use.

  In the plate-like conveyance container, the notch space for corner relief has a shape that expands inward from the opening on the storage portion side by the inner surface of the vertical and horizontal side walls, and the inner surface of the notch space of the reinforcing material It is preferable that the portion along the line has a shape corresponding to the inner surface of the notch space. Thus, the inner surface of the area near the corner is not easily removed from the opening on the storage portion side of the notch space by fitting and attaching the portion corresponding to the inner surface of the notch space of the reinforcing material to the notch space. It is possible to maintain a good wearing state along. In particular, when the lower end portion is elastically inserted into the slit of the container body, the mounting state is stable.

  The reinforcing material is made of any one of a rubber material, a synthetic resin material, and a foamed resin material, is more rigid than the container body, and has a cushioning property that can protect the plate-like body. What consists of a synthetic resin foam sheet which is more rigid and has a buffer function and an antistatic performance is preferable from the viewpoint of protecting a plate-like body such as a glass substrate.

  As described above, according to the container for transporting a plate-like body of the present invention, in the state in which the plate-like body such as a glass substrate is accommodated, the peripheral portion of the plate-like body is well protected, in particular, transportation, etc. When the plate-like body stored due to vibration or drop impact in handling of the container, especially dropping from the corner of the container moves, and the load of the plate-like body acts in the direction of the container corner, the corner angle By receiving the load from the reinforcing material attached to the area near the corner, local excessive deformation of the side wall near the corner can be suppressed, and as a result, the corner of the plate-like body is placed in the notch space of the corner. The corner portion can be prevented from coming into contact with the inner surface of the notch space, and the protection can be improved. Moreover, even if the corner portion comes into contact with the inner surface of the notch space, the occurrence of cracks and cracks from the inner surface can be suppressed.

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

  FIGS. 1-8 has shown one Example of the container for conveyance of the plate-shaped body concerning this invention. The transport container A of this embodiment is opened upward, and a plate-like body B such as a glass substrate to be stored is overlapped between each plate-like body via a protective sheet (not shown) for spacers. The container body 1 has a flat rectangular shape or a square flat rectangular shape that can be stored in the container, and a lid 3 that can be attached to the container main body 1.

  As an attachment structure of the lid body 3 to the container body 1, a notch step portion 12 is formed on the outside at the opening end portion at the upper end of the side wall of the container body 1, leaving the convex edge 11 on the inside, and the lid On the lower surface side of the peripheral edge portion 31 of the body 3, a downward-facing fitting wall portion 32 that fits and contacts the notch step portion 12 outside the convex edge 11 at the opening end portion is suspended. The lid 3 can be held in a state of being attached to the container main body 1 by the fitting by the fitting wall portion 32.

  The container body 1 is mainly formed of a synthetic resin foam having a buffering property, and a storage portion 15 is formed by vertical and horizontal side walls 14 a and 14 b rising from four sides of the bottom portion 13. The storage portion 15 is formed to a depth that can store a required number of the plate-like bodies B stacked via a protective sheet. Usually, depending on the thickness of the plate-like body B, for example, in the case of the plate-like body B such as a glass substrate having a thickness of 2 to 5 mm, it is relatively shallow so that 10 sheets or more, preferably about 10 to several tens of sheets can be accommodated. It is formed.

  At the four corners of each side wall 14a, 14b of the container body 1, a notch space 16 for corner relief extended from the inner surface side of the side wall is opened to the storage unit 15 side and is a vertical groove opened to the upper end of the side wall. It is formed in a shape. The cutout space 16 has a dovetail shape that expands inward from the opening 16a on the storage portion 15 side. The planar shape of the notch space 16 is a planar shape as shown in FIGS. 1 to 8, and is formed into a planar square shape with a part opened, as in the embodiments of FIGS. The present invention can be implemented by forming various planar shapes having a corner relief effect of B. Further, the bottom surface of the notch space 16 may be dropped from the top surface of the bottom portion 13 across the corner portion of the bottom portion 13 so that the corner portion b of the plate-like body B does not contact the bottom surface.

  A region extending from the inner surface of the cutout space 16 to the inner surfaces of the vertical and lateral side walls 14a and 14b, that is, along the inner surface of the corner vicinity region 17 including the cutout space 16, is more rigid than the container body 1 and is a plate-like body. A plate-like reinforcing material 20 made of a material having a buffering property capable of protecting B, preferably at least the same level as that of the container body 1, is detachably mounted, and the reinforcing material 20 has a side wall whose thickness is equal to the thickness. 14a and 14b are overhanging from the inner surface. For this reason, the vertical and horizontal dimensions of the storage portion 15 are set to be larger than the vertical and horizontal dimensions of the plate-like body B to be stored by at least twice the thickness of the reinforcing member 20.

  As shown in an enlarged view in FIG. 5, the reinforcing member 20 is provided with blade-shaped side portions 22 a and 22 b extending along the inner surfaces of the side walls 14 and 15 continuously to the central portion 21 corresponding to the inner surface of the notch space 17. In this state, the central portion 21 and both side portions 22a and 22b can be mounted along the inner surfaces of the vertical and horizontal side walls in a state where the central portion 21 is inserted into the notch space 17.

  The reinforcing member 20 can be attached to the inner surface of the cutout space 17 and the inner surfaces of the side walls 14a, 14b by using an adhesive means. In order to facilitate the separation work for the bottom portion 11, the inner surface of the notch space 17 and the inner surfaces of the side walls 14 a and 14 b following the inner surface of the notch space 17 in the corner vicinity region 17 are formed as shown in the illustrated embodiment. It is preferable that a slit 18 for fitting is formed at the end, and the lower end portion of the reinforcing member 20 is inserted into the slit 18 so as to be detachable. In this case, the width of the slit 18 is made the same as or slightly smaller than the thickness of the reinforcing member 20 and is elastically inserted and fitted using the elasticity of the synthetic resin foam forming the container body. It is good to carry out. Thereby, the removal | desorption operation of the reinforcing material 20 is easy, and the mounting | wearing state becomes stable.

  Reference numeral 25 in the figure denotes a cutout recess for storing and taking out the plate-like body B, which is formed in a concave groove shape extending from the upper end of the side wall to the bottom portion 13 and having the lower end dropped from the upper surface of the bottom portion 13. It is provided so that a fingertip or mechanical locking means can be hung under the body B. Reference numerals 26 and 36 denote notches and protrusions for fitting during stacking.

  In addition, the container for conveyance of the above-described embodiment is a container in which a plurality of plate-like bodies B are stacked in a container body 1 and stored in a flat state, and a lid 3 is attached and packaged. Although shown, the present invention is a case of a container having a relatively shallow storage portion in which one or several plate bodies B are stored in a flat state in the container body 1 and stacked and packaged without a lid. In addition, as in the embodiment of FIGS. 9 to 11, the reinforcing material 20 can be mounted on the corner vicinity region 17 including the notch space 16 for corner relief at the four corners.

  In the case of the container of this embodiment, the opening end at the upper end of the side wall of the container body 1 is formed with a notch step portion 12a on the inner side, leaving the fitting edge 11a on the outer side, and the lower surface of the bottom portion 13 has a peripheral edge thereof. A notch 19 in which the fitting edge 11a is fitted is provided in the portion, and the notch 19 in the bottom 13 of the upper container body 1 is fitted into the fitting edge 11a of the lower container body 1 during stacking. In addition, the inner portion of the bottom portion 13 is formed so as to fit into the notch step portion 12a.

  In the same manner as in the above-described embodiment, each corner of the container body 1 is provided with a corner relief notch space 16 extended from the inner side of the side wall and opened to the storage unit 15 and opened to the upper end of the side wall. Side walls 14a and 14b that are formed in a vertical groove shape and are continuous with the inner surface of the corner vicinity region 17 including the notch space 16, that is, the inner surface of the notch space 16 and the opening 16a from the inner surface. A reinforcing member 20 is attached along the inner surface of the detachable member, particularly detachably attached.

  The structural form of the reinforcing member 20 and the mounting means of the reinforcing member 20 of this embodiment are given the same reference numerals and the description thereof is omitted, but can be carried out in the same manner as the above-described embodiment. The planar shape of the cutout space 16 can be similarly formed.

  In any of the above examples, the constituent material of the container body 1 and the lid 3 is polystyrene, high impact polystyrene, styrene-ethylene copolymer, styrene-maleic anhydride copolymer, styrene-acrylonitrile copolymer. Foams of various synthetic resins such as polystyrene resins such as coalescence, polyolefin resins such as polyethylene, polypropylene, and ethylene-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 reinforcing member 20 is made of any one material such as a rubber material, a synthetic resin material, a foamed resin material, or a combination of two or more materials, and a central portion corresponding to the inner surface of the notch space 17. 21 and a buffer which can be formed into a shape having blade-like side portions 22a and 22b along the inner surfaces of the side walls 14 and 15 which are continuous to the side wall 14 and 15, and which is more rigid than the container body 1 and can protect the plate-like body B. A material having properties is used. Among them, a synthetic resin foam sheet that is more rigid than the container body 1 and has a buffering function and an antistatic property, for example, a foam sheet that is foamed lower than the container body 1 made of polypropylene resin is preferably used.

  The thickness of the reinforcing member 20 can be set as appropriate. However, when the stored plate-like body B is in contact with the reinforcing member 20, there is a gap between the edge of the plate-like body B and the inner surface of the side wall. Thus, for example, the thickness in the case of a foam sheet is 2 to 10 mm, preferably 3 to 7 mm. Of course, implementation outside the above range is also possible.

  According to the container A for transporting a plate-like body described above, for example, in the case of the container of the embodiment of FIGS. 1 to 8, the plate-like body B such as a base plate glass, a glass substrate for liquid crystal display, etc. On the bottom 13, the protective sheets for spacers having a thickness of 0.2 to 5.0 mm are alternately stacked and stored. At this time, along the inner surface of the corner vicinity region 17 including the notch space 16 of each corner portion of the storage portion 15, that is, the inner surface of the portion extending from the inner surface of the notch space 16 to the inner surfaces of the vertical and lateral side walls 14a and 14b. Since the reinforcing material 20 that is more rigid than the container body 1 is mounted, the plate-like body B is accommodated inside the reinforcing material 20. After storing the plate-like body B in this manner, the lid body 3 is attached to the container body 1. Then, the entire transport container A is belted (not shown) and used for transportation or the like. 9 to 11, one or several plate-like bodies are stored in a flat state in the container body 1 and stacked and packaged without a lid.

  In this use, the plate-like body B accommodated in the accommodating portion 15 is in contact with the reinforcing member 20 whose edge of the corner b portion is attached to the inner surface of the corner portion vicinity region 17 of the container body 1. Even if it contacts, the other edge part does not contact the inner surface of side wall 14a, 14b directly. In addition, the corner b of the plate-like body B is held without being in direct contact with the side walls 14a and 14b, located in the notch space 16 at the corner. When the load of the relatively heavy plate-like body B itself acts on the side walls 14a and 14b due to a drop impact during transportation and transportation, in particular, a corner drop, the load is received by the reinforcing material 20. Thus, local deformation of the side walls 14a, 14b, for example, in the vicinity of the notch space 16, can be suppressed, and therefore, the corner b of the plate-like body B can be prevented from coming into contact with the inner surface of the notch space 16, and the protection thereof is good. It can be done. Even if the corner b of the plate-like body B comes into contact with the inner surface of the notch space 16, it is possible to suppress the generation of cracks or cracks.

  The transport container of the present invention transports various types of plate-like bodies that are susceptible to impact such as raw glass, relatively large glass substrates such as glass substrates for liquid crystal displays and plasma displays, panels such as solar cell panels and touch panels. It can be suitably used for storage.
