[0008] Issues to be solved by utility models

[0009] When conveying the glass plate laminated body, the glass plate laminated body is conveyed in a state where the glass plate package is placed on the glass plate packaging tray in an inclined posture.

[0010] Glass plate packaging pallets are made of a metal frame, with foam resin or rubber cushioning elements installed on the back and bottom surfaces supporting the stacked glass plates. When these cushioning elements are secured to the pallet using adhesive, the adhesive may peel or evaporate, potentially causing contamination from the adhesive to adhere to the glass plates. Consequently, these cushioning elements may not be secured to the glass plate packaging pallet.

[0011] Even when the buffer is not fixed to the glass plate packaging pallet, when the glass plate stack is placed on the glass plate packaging pallet and transported, the glass plate stack is pressed against the glass plate packaging pallet using a fixing mechanism such as a belt, so the buffer is unlikely to shift relative to the glass plate packaging pallet. However, after the glass plate stack is transported to a customer, etc., and then the glass plate packaging pallet is transported from the customer to a glass plate manufacturing plant, the buffer is not fixed to the glass plate packaging pallet, and there is a possibility that the buffer may shift relative to the glass plate packaging pallet due to vibration or impact during transportation.

[0012] Therefore, the present invention has been made in view of the above-mentioned current problems and is characterized in providing a glass plate packaging pallet and a glass plate package in which the position of the buffer member is unlikely to shift relative to the pallet body during transportation even when no glass plates are loaded.

[0013] Solutions to Problems

[0014] The problems to be solved by the present invention are as described above, and the means for solving the problems will be described below.

[0015] That is, the glass plate packaging tray of scheme 1 of the present invention is used to support the glass plate in a tilted posture in the front-to-back direction, and is characterized in that the glass plate packaging tray includes: a back supporting portion, which supports the main surface of the glass plate; a bottom supporting portion, which supports the bottom edge of the glass plate; and a base portion, which supports the back supporting portion and the bottom supporting portion, the base portion includes a bottom surface that contacts the floor surface, the back supporting portion has a pillar uprightly arranged from the rear end of the base portion, and the center of gravity of the glass plate packaging tray is located at a position farther rearward than the middle position between the front end of the bottom surface and the rear end of the bottom surface when viewed from the side.

[0016] Thus, in the glass plate packaging pallet of the present invention, the center of gravity is located at the rear, so that even when vibration is applied to the pallet, the pallet is unlikely to swing forward. Therefore, even when no glass plates are loaded, components such as the buffer placed on the back support portion are unlikely to shift during transportation of the pallet.

[0017] In addition, the glass plate packaging pallet of Scheme 2 of the present invention is characterized in that, based on the above-mentioned Scheme 1, the center of gravity of the glass plate packaging pallet is located between the middle position and a position that is 1 / 4 of the distance between the front end of the bottom surface and the rear end of the bottom surface when viewed from the side separated from the middle position toward the rear side.

[0018] With this structure, the glass plate packaging pallet of the present invention has a center of gravity position that is further rearward than 1 / 4 of the distance between the front end and the rear end of the bottom surface when viewed from the side separated from the intermediate position toward the rear. This can easily cause the pallet to tilt rearward during transportation, storage, or loading, leading to breakage of the glass plates. By setting the center of gravity position to 1 / 4 or less, this can be prevented.

[0019] Furthermore, the glass plate packaging tray according to claim 3 of the present invention is characterized in that, in addition to claim 1 or 2, the height of the center of gravity of the glass plate packaging tray is smaller than the distance between the front end and the rear end of the bottom surface in a side view.

[0020] With this structure, the center of gravity is lowered, improving stability during transportation, storage, and loading operations.

[0021] In addition, the glass plate packaging tray of Scheme 4 of the present invention is characterized in that, based on any one of the above-mentioned Schemes 1 to 3, the distance from the front end of the bottom surface to the rear end of the bottom surface when viewed from the side is larger than the distance from the front end of the bottom supporting part to the rear end of the back supporting part when viewed from the side.

[0022] With this structure, the stability of the pallet body is improved.

[0023] Furthermore, a glass plate packaging tray according to claim 5 of the present invention is characterized in that, in addition to any one of claims 1 to 4, the front end of the bottom surface is located forward of the front end of the bottom receiving portion.

[0024] With this structure, the tray body is less likely to swing forward.

[0025] In addition, the glass plate packaging tray according to claim 6 of the present invention is characterized in that, in addition to any one of claims 1 to 5, the ratio H / D of the height dimension H of the glass plate packaging tray to the distance D from the front end to the rear end of the bottom surface when viewed from the side is greater than or equal to 0.9 and less than or equal to 3.

[0026] With this structure, H / D is 0.9 or more, which prevents the floor space from becoming too large and improves transportation efficiency. H / D is 3 or less, which improves stability during transportation and storage.

[0027] In addition, the glass plate packaging tray of Scheme 7 of the present invention is based on any one of the above-mentioned Schemes 1 to 6, and is characterized in that the back supporting portion includes: a back buffer that abuts the main surface of the glass plate; and a back supporting surface that supports the back buffer, and the back buffer is configured to be non-adhesive and separable from the back supporting surface.

[0028] This structure prevents the adhesion of dirt from the adhesive and facilitates replacement of the cushioning member if it deteriorates. Furthermore, the thermal expansion coefficient of the resin cushioning member differs from that of the metal tray body, potentially causing damage when bonded. However, by configuring the cushioning member so that it can be separated without bonding, damage to the cushioning member can be prevented.

[0029] In addition, the glass plate package according to claim 8 of the present invention is characterized in that a glass plate laminate obtained by laminating a plurality of glass plates is placed on the glass plate package tray according to any one of claims 1 to 7, and the center of gravity of the glass plate package is located rearward of the middle position.

[0030] With this structure, the center of gravity of the glass plate package is positioned rearward, so that the glass plate package is less likely to swing forward, and collapse of the glass plates can be prevented.

[0031] In addition, the glass plate package according to claim 9 of the present invention is characterized in that, in addition to claim 8, the center of gravity of the glass plate package is located between the middle position and a position that is 1 / 4 of the distance between the front end and the rear end of the bottom surface when viewed from the side separated from the middle position toward the rear.

[0032] With this structure, if the distance between the center of gravity of the glass plate package and the center of the pallet in the front-to-back direction is greater than 1 / 4, the pallet will tend to tilt backward during transportation, storage, or loading, and the glass plates may break. By setting the distance to 1 / 4 or less, this problem can be prevented.

[0033] In addition, the glass plate package according to claim 10 of the present invention is characterized in that, in addition to claim 9, the center of gravity of the glass plate package is located between the middle position and a position that is 1 / 5 of the distance between the front end and the rear end of the bottom surface when viewed from the side separated from the middle position toward the rear.

[0034] With this structure, if the distance between the center of gravity of the glass plate package and the center of the pallet in the front-to-back direction is greater than 1 / 5, the pallet will tend to tilt backward during transportation, storage, or loading, and the glass plates may break. By setting the distance to 1 / 5 or less, this problem can be prevented.

[0035] Utility model effect

[0036] The following effects are achieved as the effects of the present invention.

[0037] That is, the glass plate packaging pallet and the glass plate package of the present invention can provide a glass plate packaging pallet and a glass plate package in which the buffer member is unlikely to be displaced relative to the pallet body during transportation even when no glass plates are loaded.

[0051] Next, use Figures 1 to 4 An embodiment of the present invention will be described.

[0052] It should be noted that in Figures 1 to 4 In the description, the front-rear direction, the left-right direction, and the up-down direction of the glass plate package 1 are defined by the directions of arrows.

[0053] [Overall Structure of Glass Plate Package 1]

[0054] First, use Figure 1 The entire structure of the glass plate package 1 embodying the present invention will be described.

[0055] The glass plate package 1 in the present embodiment is an example of a package form for collecting a plurality of glass plates G for transportation, storage, and the like.

[0056] The glass plate package 1 is a package in which a glass plate laminate 10 , which is a laminate of a plurality of glass plates G, is placed in a vertical orientation on a glass plate packaging pallet 20 (hereinafter simply referred to as a “tray”).

[0057] Here, in this embodiment, the glass plates G packaged in the glass plate package 1 are rectangular flat glass plates used, for example, as substrates or cover glasses for displays such as liquid crystal displays and organic EL displays, and their outer dimensions (vertical x horizontal) are set to be not less than 1500 mm x 1500 mm and not more than 3500 mm x 3500 mm, and their thickness is set to be not less than 0.2 mm and not more than 2.0 mm.

[0058] The glass plate laminate 10 includes a plurality of glass plates G and a plurality of protection sheets S interposed between the plurality of glass plates G. As shown in FIG.

[0059] The tray 20 includes a back receiving portion 21 that supports the back surface of the glass plate G ( Figure 1 bottom receiving portion 22, which supports the bottom edge of the glass plate G; and a base portion 23, which supports the back receiving portion 21 and the bottom receiving portion 22.

[0060] The back support portion 21 includes a back support surface 21a that supports the back side of the main surface of the glass sheet G, and a frame structure 21b that supports the back support surface 21a. The back support surface 21a is a surface for placing the back side of the glass sheet G and is formed from a rectangular flat plate. Furthermore, the frame structure 21b is a skeletal structure that supports the back support surface 21a and includes a plurality of beams 21c that support the rear side of the back support surface 21a and pillars 21d that connect to the rear ends of the beams 21c and are arranged vertically. The back support surface 21a of the back support portion 21 is arranged to stand approximately at a right angle to the upper surface 22a of the bottom support portion 22.

[0061] The bottom receiving portion 22 is formed by a horizontal direction and a direction (in Figure 1 The glass plate G is placed on the upper surface 22a of the bottom receiving portion in a vertical position.

[0062] The glass sheet G placed on the upper surface 22a of the bottom receiving portion 22 in a vertical position is supported on the back surface (rear surface) by the back support surface 21a of the back receiving portion 21, thereby Figure 1The rear side is in the middle) and is kept in a slightly tilted (inclined) state.

[0063] The base portion 23 includes, for example, a rectangular base frame 23a in a plan view extending in the horizontal direction, and a plurality of support blocks 23b extending along one end portion (at the top of the base frame 23a) on the upper surface of the base frame 23a. Figure 1 The bottom receiving portion 22 is supported by the front end portion in the middle. A bottom surface 23c that contacts the floor surface is provided at the lower end of the base portion 23, and a plurality of support columns 23d are arranged between the base frame 23a and the bottom surface. In addition, at the other end portion of the base frame 23a (at Figure 1 The rear end portion is in the middle), and is connected to a support column 21d erected in the up-down direction.

[0064] When the glass plate laminate 10 is supported by the back support portion 21 and the bottom support portion 22 of the tray 20, a back cushion 25 and a bottom cushion 26 are provided between the back support surface 21a of the back support portion 21 and the upper surface 22a of the bottom support portion 22, and the glass plate laminate 10. The back cushion 25 is a member that contacts the rear main surface of the glass plate laminate 10 and is placed on the back support surface 21a of the back support portion 21. The back cushion 25 is configured to be detachable from the back support surface 21a without being adhered to it. The back cushion 25 is a plate-shaped member made of, for example, foamed polypropylene, and is formed from a material having excellent load resistance and impact resistance.

[0065] The bottom bumper 26 is a member that contacts the bottom surface of the glass sheet laminate 10 and is placed on the upper surface 22a of the bottom receiving portion 22. The bottom bumper 26 is disposed so as to be detachable from the upper surface 22a without being adhered to it. The bottom bumper 26 is a sheet formed of an elastic member such as rubber and is made of a material having excellent load and impact resistance.

[0066] like Figure 1 As shown, the glass plate package 1 is configured such that a glass plate stack 10 formed by stacking a plurality of glass plates G and a protective sheet S is placed on a tray 20. With the glass plate stack 10 placed, the glass plate stack 10 and the tray 20 are brought together and wrapped with a fixing mechanism such as a band to prevent the glass plate stack 10 from separating from the tray 20 and falling over.

[0067] When the glass plate package 1 is placed on the pallet 20 and transported, the glass plate laminated body 10 is pressed against the pallet 20 using a fixing mechanism such as a belt. Therefore, the back surface cushion member 25 and the bottom surface cushion member 26 are unlikely to shift relative to the pallet 20 .

[0068] However, if Figure 2As shown, after the glass plate stack 10 is transported to a customer, etc., when the pallet 20 is transported from the customer, etc. to a manufacturing plant for the glass plate G, the back buffer 25 and the bottom buffer 26 are not fixed relative to the pallet 20, and the back buffer 25 and the bottom buffer 26 may be offset relative to the pallet 20 due to vibration or impact during transportation.

[0069] Therefore, a structure is required to prevent the back surface cushion 25 and the bottom surface cushion 26 from being displaced relative to the tray 20 when the back surface cushion 25 and the bottom surface cushion 26 are not fixed relative to the tray 20 .

[0070] like Figure 3 As shown, the center of gravity G1 of the tray 20 is located rearward of the intermediate position C between the front end and the rear end of the bottom surface 23c when viewed from the side. Preferably, the center of gravity G1 of the tray 20 is located between the intermediate position C and a position L1 that is 1 / 4 of the distance D between the front end and the rear end of the bottom surface 23c when viewed from the side, separated from the intermediate position C. More preferably, the center of gravity G1 of the tray 20 is located between the intermediate position C and a position L2 that is 1 / 5 of the distance D between the front end and the rear end of the bottom surface 23c when viewed from the side, separated from the intermediate position C.

[0071] like Figure 3 As shown, when the distance from the middle position C to the center of gravity position G1 is D1 and the rearward length is positive, the distance D1 is greater than 0. The distance D1 is preferably smaller than D / 4, and more preferably smaller than D / 5.

[0072] Here, the center of gravity position G1 of the pallet 20 is the center of gravity position when the glass plate laminate 10 is removed from the glass plate package 1 and the back surface cushion 25 and the bottom surface cushion 26 are placed on the back support surface 21 a and the upper surface 22 a of the pallet 20 .

[0073] The middle position C is the middle position of the distance D from the front end to the rear end of the bottom surface 23c, and does not include the rear end of the block or the like even if other components such as the block are provided at a position rearward of the bottom surface 23c.

[0074] Thus, the center of gravity position G1 is located rearward of the intermediate position C. Therefore, when the pallet 20 is transported from a customer or the like to a manufacturing plant for the glass sheets G, the center of gravity position G1 is located rearward, and thus the pallet 20 is less likely to swing forward even when vibration or shock is applied to the pallet 20. Therefore, even when no glass sheet laminates 10 are loaded, the back surface cushioning member 25 placed on the back support portion 21 is less likely to shift during transport of the pallet 20.

[0075] Furthermore, if the center of gravity position G1 is positioned rearward of the position L1 that is 1 / 4 of the distance D between the front end and the rear end of the bottom surface 23c when separated rearward from the intermediate position C, the tray 20 is likely to tilt rearward during transportation, storage, or loading, and the glass sheet G is likely to break. Therefore, by positioning the center of gravity position G1 of the tray 20 between the intermediate position C and the position L1 that is 1 / 4 of the distance D between the front end and the rear end of the bottom surface 23c when separated rearward from the intermediate position C, the tray 20 is less likely to tilt rearward during transportation, storage, or loading, thereby preventing the glass sheet G from breaking.

[0076] Furthermore, by positioning the center of gravity G1 between the intermediate position C and a position L2 spaced rearward from the intermediate position C by 1 / 5 of the distance D between the front end and the rear end of the bottom surface 23c, malfunctions can be more reliably prevented.

[0077] Furthermore, the height Hg of the center of gravity G1 of the pallet 20 is smaller than the distance D between the front end and the rear end of the bottom surface 23c when viewed from the side. The height Hg of the center of gravity G1 is the height from the floor surface to the center of gravity G1. This configuration lowers the center of gravity G1, improving stability during transportation, storage, and loading operations.

[0078] Furthermore, the distance D from the front end to the rear end of the bottom surface 23c in side view is greater than the distance D2 from the front end of the bottom support portion 22 to the rear end of the back support portion 21 in side view.

[0079] Here, the front end of the bottom receiving portion 22 refers to the position of the front end of the bottom receiving portion 22 when viewed from above, for example, Figure 3 The front end of the upper surface 22a is formed in the middle. Figure 3 In the embodiment, the front end of the bottom surface 23c is located in front of the front end of the bottom support portion 22. In addition, the rear end of the back support portion 21 refers to the rear end of the support 21d constituting the back support portion 21. Figure 3 The middle is at the same position as the rear end of the bottom surface 23c in the front-rear direction.

[0080] Furthermore, a ratio H / D of the height dimension H of the tray 20 and the distance D from the front end to the rear end of the bottom surface 23 c in a side view is 0.9 or more and 3 or less.

[0081] Here, the height dimension H of the tray 20 is the height from the floor surface to the back receiving portion 21 .

[0082] With this structure, H / D is 0.9 or more, which prevents the floor space from becoming too large and improves transportation efficiency. H / D is 3 or less, which prevents the height of the tray 20 from becoming too large and improves stability during transportation and storage.

[0083] In addition, the inclination angle θ of the back support surface 21a of the back support portion 21 is greater than 15° and less than 45°. By forming it in this way, the floor space does not become too large, thereby improving the transportation efficiency. That is, the space of the vehicle configured for transportation can be reduced, thereby improving the transportation efficiency.

[0084] In addition, if Figure 4 As shown, the center of gravity G2 of the glass plate package 1, which has the glass plate laminates 10 placed on the tray 20, is located rearward of the intermediate position C between the front end and the rear end of the bottom surface 23c in side view. Preferably, the center of gravity of the glass plate package 1 is located between the intermediate position C and a position L1 that is ¼ of the distance between the front end and the rear end of the bottom surface 23c when separated from the intermediate position C in side view. More preferably, the center of gravity of the glass plate package 1 is located between the intermediate position C and a position L2 that is ½ of the distance between the front end and the rear end of the bottom surface 23c when separated from the intermediate position C in side view.

[0085] like Figure 4 As shown, when the distance from the middle position C to the center of gravity position G2 is D3 and the rearward length is positive, the distance D3 is greater than 0. The distance D3 is preferably smaller than D / 4, and more preferably smaller than D / 5.

[0086] Here, the center of gravity position G2 of the glass plate package 1 is the center of gravity position when the glass plate laminate 10 , the back surface cushion material 25 , and the bottom surface cushion material 26 are placed on the back surface support surface 21 a and the upper surface 22 a of the pallet 20 .

[0087] The middle position C is the middle position of the distance from the front end to the rear end of the bottom surface 23c. For example, even if other components such as a block are provided at a position rearward of the bottom surface 23c, the rear end of the block or the like is not included.

[0088] Thus, since the center of gravity position G2 is located rearward of the intermediate position C, the glass plate package 1 is less likely to swing forward even when vibration is applied to the glass plate package 1 during transportation and storage. Therefore, the glass plate package 1 is less likely to swing forward during transportation of the glass plate package, and collapse of the glass plates G can be prevented.

[0089] Furthermore, if the center of gravity position G2 is located further rearward than the position L1, which is 1 / 4 of the distance between the front end and the rear end of the bottom surface 23c when separated from the intermediate position C toward the rear, the glass plate package 1 is likely to tilt rearward during transportation, storage, or loading, and the glass plates G are likely to break. Therefore, by positioning the center of gravity position G2 of the glass plate package 1 between the intermediate position C and the position L1, which is 1 / 4 of the distance between the front end and the rear end of the bottom surface 23c when separated from the intermediate position C toward the rear, the tray 20 is less likely to tilt rearward during transportation, storage, or loading, thereby preventing the glass plates G from breaking.

[0090] Furthermore, since the center of gravity position G2 is located between the middle position C and a position L2 spaced rearward from the middle position C by 1 / 5 of the distance between the front end and the rear end of the bottom surface 23c, malfunctions can be more reliably prevented.

[0091] Example

[0092] Hereinafter, the present invention will be described based on the following examples. It should be noted that the following examples are simply illustrative and the present invention is not limited to the following examples.

[0093] Four pallets each having the dimensions shown in Table 1 for Examples 1 to 4 and Comparative Examples 1 and 2 were prepared and transport tests were conducted as follows. First, acceleration sensors were attached to the top ends of four pallets for each of the Examples and Comparative Examples. The pallets were loaded onto the cargo bed of a truck and driven for 200 km. The presence of back and bottom cushioning deflections of 10 mm or more was then checked, along with the average value of the acceleration sensor measurements.

[0094] Table 1

[0095]

[0096] In the pallets of Examples 1 to 4, the position of the center of gravity is located further to the rear than the middle position between the front end and the rear end of the bottom surface when viewed from the side, and there is no back buffer and the offset of the bottom buffer is more than 10 mm. In addition, the average acceleration of the upper end of the pallet is less than 0.6 G, and the acceleration acting on the pallet due to vibration and impact during transportation is small. On the other hand, in the pallets of Comparative Examples 1 and 2, the position of the center of gravity is located further to the front than the middle position between the front end and the rear end of the bottom surface when viewed from the side, and the offset of the back buffer and the bottom buffer is more than 10 mm. In addition, the average acceleration of the upper end of the pallet is more than 1.7 G, and the acceleration acting on the pallet due to vibration and impact during transportation is large.

[0097] The above describes an embodiment of the present invention, but the present invention is not limited by this embodiment and is ultimately an example. Of course, it can be implemented in various ways without departing from the main purpose of the present invention. The scope of the present invention is represented by the record of the utility model technical solution, and also includes the equivalent meaning recorded in the utility model technical solution and all changes within the scope.
