  The conventional plate-shaped body storage case stores the glass substrate so that the glass substrate protrudes to a certain extent outside the upper opening of the case body when the glass substrate is inserted into the case body. That is, when the depth of the case main body is made shorter than the length of the side in the glass substrate insertion direction, the operation of putting the glass substrate in and out of the case main body becomes easier. Normally, the glass substrate is put in and out of the case main body by an unpacker device, but at the time of receiving and inspecting the glass substrate, it is manually performed by an inspector.

  By the way, when the glass substrate is put in and out by the inspector's hand, the inspector presses the fingers of both hands against both corners of the glass substrate protruding from the case main body and puts force in the surface direction of the glass substrate, that is, The glass substrate is lifted from the case body with the glass substrate sandwiched in the surface direction. At this time, the vicinity of both corners of the glass substrate against which the finger is pressed is not supported by the groove of the case body, and is supported by the groove. Since the length of both sides of the glass substrate which is not long is long, the glass substrate is easily bent. When the amount of bending of the glass substrate increases, the bent portion comes into contact with the adjacently stored glass substrate, so that both glass substrates are scratched and the glass substrate becomes defective, and the glass substrate is a case main body. There was a problem that it would be difficult to take out.

  This problem frequently occurs in a storage case that stores a glass substrate horizontally, that is, a storage case that lifts a glass substrate stored in a case body with its short sides sandwiched between fingers.

  The edge of the glass substrate supported by the groove is not the quality surface of the glass substrate, and the quality surface of the glass substrate is the inner surface at a position approximately 10 mm from the edge of the glass substrate to the inside of the glass substrate. It is. This quality has been scratched in the past.

  The present invention has been made in view of such circumstances, and a plate-shaped body storage capable of preventing the plate-shaped body from being damaged by suppressing the bending of the plate-shaped body when the plate-shaped body is taken out from the case main body. An object is to provide a guide member for taking out a case.

  In order to achieve the above object, the present invention is configured in a box shape having an open top, and provided with first grooves for supporting both edge portions of the plate-like body on opposite inner walls thereof. In a plate-shaped body storage case comprising a case main body for storing the plate-shaped body so that an edge protrudes a predetermined amount from the opening of the case main body, the upper portion of the plate-shaped body supported by the first groove, A cylindrical takeout guide member in which the lower opening is put on the opening of the case body, and second grooves are provided on the opposing inner walls to support both edges of the plate-like body, When covering the opening of the case body, both edges of the plate-like body protruding from the opening of the case body are supported by the second groove, and the plate-like body protruding from the opening of the case body The height is set lower than the height of the protrusion. Providing retrieval guide member of the plate-like body housing case to.

  According to the present invention, when the lower opening of the guide member for extraction is put on the opening of the case main body in which the plate-like body is accommodated, both edges of the protruding portion of the plate-like body protruding from the opening of the case main body are That is, both edge portions of the plate-like body not supported by the first groove of the case body are supported by the second groove of the extraction guide member. Further, since the height of the guide member for extraction is set lower than the height of the protruding portion of the plate-like body protruding from the opening of the case body, the plate-like body protruding from the upper opening of the guide member for extraction Grip a small amount of the protruding part by hand and take out the plate-like body from the case body. At the time of taking out the plate-like body, the plate-like body receives a surface force by hand, but both edges of the protruding portion of the plate-like body protruding from the opening of the case main body are the second guide member for extraction. Since it is supported by the groove, the plate-like body is taken out from the case body in a state in which the bending is suppressed. Therefore, by using the take-out guide member of the present invention, the plate-like body does not come into contact with the plate-like body accommodated adjacently, so that the plate-like body can be prevented from being damaged.

  In the present invention, the thickness of the plate-like body is preferably 0.3 to 0.5 mm.

  According to this invention, it is suitable for the plate-shaped body used as protective glass of the board | substrate for organic EL, for example whose thickness of a plate-shaped body is 0.3-0.5 mm.

  In the present invention, it is preferable that the pitch of the second groove is 10 to 15 mm.

  According to the present invention, by supporting the plate-like bodies at this pitch, contact between adjacent plate-like bodies while being supported by the second groove is prevented.

  As described above, according to the storage case of the plate-shaped body of the present invention, it is possible to prevent the plate-shaped body from being damaged by suppressing the bending of the plate-shaped body when the plate-shaped body is taken out from the case main body.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a guide member for taking out a plate-shaped body storage case according to the present invention will be described with reference to the accompanying drawings.

  FIG. 1 shows an overall perspective view of a glass substrate storage case 10 in which the take-out guide member 30 (see FIG. 3) of the embodiment is used. As shown in FIG. 2, the storage case 10 includes a case main body 12, a support member 14, a lid 16, and male and female magic tapes (Kuraray Fastening Co., Ltd .: registered trademarks) 18 and 18. Further, the rectangular glass substrate G indicated by a two-dot chain line in FIG. 2 stored in the storage case 10 is used as a protective glass for an organic EL substrate, and has a short side of 400 mm, for example. As described above, the long side is 700 mm or more and the thickness is 0.3 to 0.5 mm, and it is easy to bend when a force is applied in the surface direction.

  The case main body 12 is configured as a rectangular parallelepiped box having an open top, and is made of a strong polypropylene-based foam. The thickness of the case body 12 takes into consideration the balance of strength, load resistance, hardness, elasticity, and the like. Further, a plurality of grooves (first grooves) 20, 20... For supporting the glass substrate G in the horizontally long direction are formed on the pair of inner walls facing each other of the case body 12 at a predetermined interval.

  The groove 20 is formed to a depth that allows insertion of both edges on the short side of the glass substrate G, and is formed so that there is a slight gap when the glass substrate G is inserted. .. Corresponding to the groove 20 are also formed on the inner bottom surface of the case body 12 to support the lower edge of the glass substrate G. The number of the grooves 20 and 22 is arbitrarily set, but may be about 10 to 20 or more per surface. Further, the cross-sectional shape of the grooves 20 and 22 may be V-shaped, Y-shaped or I-shaped. However, from the viewpoint of ease of insertion of the glass substrate G, a V shape is preferable. Further, the interval between the grooves 20 and 20 and the interval between the grooves 22 and 22 is set to about 10 to 15 mm. This interval is different from the number of fillings in the case and the adjacent glass substrates G and G in the case filling state. It can be set arbitrarily considering that there is no contact. Furthermore, the distance between the glass substrates G and G inserted on both sides of the case body 12 and the inner wall surface of the case body 12 facing the glass substrates G and G is about 25 mm in consideration of handling work by the unpacker device. Is set to

  The support member 14 is a horizontal plate that protects the upper surface of the protruding portion of the glass substrate G inserted into the case main body 12 from the opening of the case main body 12, and has an expansion ratio of about 20 times in order to improve impact resistance. Polyethylene foam is used. Further, a plurality of V-shaped grooves 24, 24... Supporting the upper edge of the glass substrate G are formed on the lower surface of the support member 14 at the same interval as the intervals of the grooves 20, 20. By supporting the upper edge of the glass substrate G in the V-shaped groove 24, rattling between the glass substrate G and the lid body 16 is prevented via the support member 14.

  The lid body 16 has a box shape, and a case is formed so as to wrap the support member 14 in a state where the support member 14 is attached to a protruding portion of the glass substrate G inserted into the case body 12 from the opening of the case body 12. It covers the opening of the main body 12.

  The lid body 16 is made of a polypropylene foam like the case body 12, and the expansion ratio is the same as that of the case body 12. Note that the thickness of the lid body 16 is set to be thinner than the case main body 12 because it does not require as much strength as the case main body 12.

  The male and female magic tapes 18, 18 are attached so as to face the upper surface side of the support member 14 and the inner surface side of the top surface 16 a of the lid 16. Therefore, when the lid body 16 is removed from the case main body 12, the support member 14 is also removed together with the lid body 16 by the engaging force between the male and female magic tapes 18 and 18. The number of the magic tapes 18 and 18 is not limited to two each, and may be one or three or more. The size of the magic tape 18 is also set as appropriate.

  When the storage case 10 configured in this way is used, first, the glass substrates G, G,... Are sequentially inserted in the laterally long direction using the grooves 20, 20,. As a result, the plurality of glass substrates G, G... Are stored in the case body 12 at a predetermined interval. Next, the V-shaped grooves 24, 24... Of the support member 14 are engaged with the upper edges of the protruding portions of the glass substrates G, G... From the case body 12 to protect the protruding portions of the glass substrates G, G. To do. Next, the lid 16 is placed over the opening of the case body 12 so as to wrap the support member 14. Accordingly, the glass substrates G, G... Are stored in the storage case 10. Then, the storage case 10 is taped with a tape (not shown) and packaged, and the storage case 10 is transported from the glass substrate G manufacturing factory to the assembly factory in this packaging form. A plurality of grooves 26, 26... For hanging the tape in the vertical direction are formed on the outer surfaces of the case body 12 and the lid body 16.

  Next, when taking out the glass substrate G from the storage case 10 in the assembly factory, first, the lid body 16 is removed from the case body 12. Thereby, the support member 14 is removed from the case body 12 side together with the lid 16 by the engaging force of the male and female magic tapes 18 and 18. Therefore, if the cover body 16 is removed, the protruding portion of the glass substrate G is exposed from the case main body 12, so that the glass substrate can be taken out from the case main body 12 at the assembly factory. The support member 14 bonded to the lid body 16 by the male and female magic tapes 18 and 18 is removed from the lid body 16 by hand and used for the next packing operation.

  Next, a method for taking out the glass substrate G to be inspected from the case body 12 using the take-out guide member 30 of the embodiment shown in FIG. 3 will be described.

  The take-out guide member 30 is formed in a rectangular rectangular tube shape having openings at the lower part and the upper part, and is made of a polypropylene-based foam like the case main body 12 and the lid body 16. The lower opening of the extraction guide member 30 is formed in the same shape as the opening of the case body 12. The lower opening is placed over the opening of the case body 12, so that the extraction guide member 30 is detachably attached to the case body 12. Further, V-shaped grooves (second grooves) 32, 32,... That support both edge portions on the short side of the glass substrate G are provided on opposing inner walls of the guide member 30 for extraction. The pitch of the grooves 32 and 32 is also set to about 10 to 15 mm similarly to the pitch between the grooves 20 and 20. Therefore, by supporting the glass substrates G, G... At this pitch, contact between the adjacent glass substrates G, G in a state supported by the grooves 32, 32 is prevented.

  When the extraction guide member 30 is placed over the opening of the case body 12, both edges on the short side of the glass substrate G protruding from the opening of the case body 12 are supported by the grooves 32, 32. Further, the height (H) of the extraction guide member 30 is set to be lower than the height (I) of the protruding portion of the glass substrate G protruding from the opening of the case body 12. For example, the height (I) is set to about 80 mm, and the height (H) is set to about 55 mm. Thereby, the height (J) of the protrusion part of the glass substrate G protruded from the upper opening part of the guide member 30 for extraction is set to about 25 mm, and is small.

  Next, a procedure for taking out the glass substrate G from the case body 12 using the take-out guide member 30 will be described.

  First, the case main body 12 in which the glass substrate G is accommodated is placed on the inspection table so that the opening faces upward. Next, both edges on the short side of the protruding portion of the glass substrate G protruding from the opening of the case body 12, that is, on the short side of the glass substrate that is not supported by the grooves 20, 20,. The lower opening of the extraction guide member 30 is covered with the opening of the case body 12 while both edges are supported by the grooves 32 of the extraction guide member 30.

  At this time, the height (H) of the extraction guide member 30 is lower than the height (I) of the protruding portion of the glass substrate G protruding from the opening of the case body 12, so that the extraction guide member as shown in FIG. The height (J) of the protruding portion of the glass substrate G protruding from the upper opening 30 is small, and the inspector holds the small protruding portion by hand to take out the glass substrate G from the case body 12.

  For example, as shown in FIGS. 4 and 5, the thumb A of both hands of the inspector is applied to the vicinity of the corner of the upper edge of the glass substrate G, and the index finger B and the middle finger C of both hands are pressed to the vicinity of the corner of the side edge. In this state, the glass substrate G is taken out from the case main body 12 through the take-out guide member 30. By this way of taking out, the glass substrate G can be taken out from the case main body 12 without attaching dirt due to the fingers A to C to the quality surface of the glass substrate G.

  At the time of taking out the glass substrate G, the glass substrate G tries to bend by receiving the force in the surface direction by the index finger B and middle finger C of the inspector as shown by the solid line in FIG. 6, but protrudes from the opening of the case body 12. Since both edges on the short side of the protruding portion of the glass substrate G are supported by the grooves 32, 32... Of the extraction guide member 30 as shown in FIG. 4, the glass substrate G is prevented from being bent as shown in FIG. In this state, it is taken out from the case body 12.

  Therefore, by using the take-out guide member 30 of the embodiment, the glass substrate G to be taken out does not come into contact with the adjacent glass substrate G in the case main body 12, so that the glass substrate G is damaged. And the rate of non-defective products in the cassette storage / removal operation was significantly improved.

  The object to be stored in the plate-shaped body storage case of the present invention is not limited to the protective glass of the organic EL substrate, but is a thin FPD glass substrate such as a liquid crystal display or a plasma display, or a resin or metal plate that is easily bent. The object may be a target.
