Description

  The present invention relates to a packing tool, a packing container, a packing body, a method for packing a glass substrate, and a method for unpacking the packing body. In particular, as a glass substrate, a flat panel display (FPD), that is, a liquid crystal display or a plasma display is used. Packing tools, packing containers, packing bodies, packing methods for glass substrates, and unpacking of packing bodies used for packing large glass substrates, intermediate glass substrates in the manufacturing process, etc. It is about the method.

In recent years, needs for large plate glass used for FPD glass and the like are increasing. As a means for storing and transporting such a large plate glass, as shown in Patent Document 1, a packaging rack in which each plate glass is fixed in a state where a plurality of plate glasses are arranged upright is known. However, a large plate glass having a height of 2 m or more, for example, cannot be stacked on a conventional track and requires a low floor track. Further, when transporting the plate glass in an upright state, the dimension of one side of the bottom surface is increased to ensure the stability of the packaging box (for example, 0.5 times the height of the packaging box). However, because the number of plate glasses that can be loaded in a single packaging box is limited due to the restrictions on the load capacity of forklifts and the floor load capacity of the manufacturing site, the volume and weight of the packaging box increase with respect to the number of plate glasses loaded. , Storage efficiency and transport efficiency are reduced.
Further, when the plate glass is conveyed in a standing state, the weight of the plate glass is concentrated on the bottom side of the glass, and the plate glass may be damaged by a slight impact.

Patent Documents 2 and 3 disclose a packing method for storing a plurality of plate glasses in a flat position. Patent Document 2 describes that the movement of the plate glass can be controlled by sandwiching the plate glass with the foamed resin sheet, making the foamed resin sheet larger than the plate glass, and making it substantially the same as the storage space. However, when acceleration / deceleration, vibration, etc. of the track are applied, the glass plate is displaced from a predetermined position, making it difficult to automatically plate in a later process. Further, if the plate glass is greatly displaced, it will come into contact with the box and the plate glass will have defects such as chipping, wrinkling and cracking.
Also, when taking out flat glass sheets one by one, a certain gap is provided between the glass sheets at the packing stage, and a jig for taking out is inserted into this gap to lift the glass sheet. Is common. However, if a gap is provided between the plate glasses during packing, the number of plate glasses stored in the storage space may be reduced.
Patent Document 3 describes a packing method in which a plate glass is sucked and held by a support member. However, with this method, the storage efficiency is poor, the packaging case is complicated and expensive, and the operation is troublesome.

The plate glass has been described above, but the same applies to plate-like bodies such as resin plates and metal plates.

As shown in FIG. 1 and FIG. 2, the packing tool 1 of the present embodiment is schematically configured from a frame body 2 and a hanging device 3 attached to the frame body 2.
The frame body 2 includes an upper frame 21, a lower frame 22, and a pair of side frames 23 and 23 that connect the upper frame 21 and the lower frame 22. An area surrounded by the frames 21 to 23 is a storage area 24. The storage area 24 is a space for storing a glass substrate that is an object to be packed, and is formed to be slightly larger than the size of the glass substrate. The frame 2 is made of, for example, a metal material such as aluminum, an aluminum alloy, stainless steel, or SS, a resin material, or the like. Moreover, the thickness of each frame 21-23 which comprises the frame 2 is set to the thickness of about several times thru | or several dozen times the thickness of the glass substrate which is a to-be-packaged object, for example, it is 5-40 mm. preferable. The frames 21 to 23 can be divided from each other, and the frame body 2 can be disassembled when the packing tool 1 is not used.

  Moreover, as shown in FIGS. 1-3, the frame 2 is provided with the convex part 2c in the one surface 2a side, and the recessed part 2d is provided in the other surface 2b side. The convex portion 2 c and the concave portion 2 d are formed so as to surround the accommodation region 24. Moreover, the convex part 2c and the recessed part 2d are shape | molded in the shape which can be mutually fitted. Accordingly, when a plurality of packing tools 1 are prepared, the packing tools 1 can be integrated with each other by fitting the convex portions 2c and the concave portions 2d of the packing tools 1 together.

  Next, the suspending device 3 hangs and fixes the glass substrate to the accommodation area 24. For example, as shown in FIG. 3, there is a clip 3a that holds and holds the glass substrate from both sides in the thickness direction. It is done. The clip 3a is attached to the upper frame 21 by a plate-like support member 3b. As shown in FIG. 1, the clip 3 a (the hanging device 3) extends along the longitudinal direction of the upper frame 21, thereby fixing the entire side of the glass substrate. It may be divided into two or more. The material of the clip 3a and the support member 3b is made of a metal material such as aluminum, aluminum alloy, stainless steel, or SS. Moreover, you may affix the protective layer which consists of resin or rubber | gum on the part which contacts a glass substrate among the clips 3a, in order to prevent wrinkles generation | occurrence | production of a glass substrate.

  Further, the packing tool 1 is provided with a pressing member 4 that prevents the suspended glass substrate from shaking. In the packing tool 1 shown in FIG. 1, as the pressing member 4, two wires 4 a and 4 b stretched between the side frames 23 are illustrated. Each wire 4a, 4b is respectively arrange | positioned at the one surface 2a side and the other surface 2b side of the thickness direction of a glass substrate, and has a structure which pinches | interposes a glass substrate with wire 4a, 4b. The wires 4a and 4b are attached to the packing tool 1 so as to be easily removable, and the wires 4a and / or 4b are removed when the glass substrate is stored and taken out. The material of the wires 4a and 4b is preferably a resin or rubber from the viewpoint of preventing the glass substrate from being wrinkled, and when a metal wire is used, the surface thereof is preferably covered with a resin or the like. Further, as the pressing member, a belt-shaped member may be used instead of the wire. Further, a stopper may be provided on the lower frame 22 or the side frame 23, and this stopper may be used as a pressing member.

An example of the glass substrate shown in FIG. 4 is a glass substrate 5 for a display device such as a flat panel display. This glass substrate 5 is a glass substrate having a rectangular shape in plan view with a length of any one of the vertical and horizontal sides of 2 m or more and a thickness of 0.4 to 1.1 mm. One side 5 a of the glass substrate 5 is held by the suspension device 3 and is suspended in the accommodation region 24. Since the accommodation region 24 is formed to be slightly larger than the glass substrate 5 as described above, all three sides including the bottom side 5 b of the glass substrate 5 are separated from the frame body 2 and are not in contact with the frame body 2. Therefore, the stress applied to the glass substrate 5 is concentrated in the vicinity of the side 5a held by the hanging device 3, and is not applied to other portions. Further, the outer peripheral portion of the glass substrate 5 is an ineffective area, and this ineffective area is held by the hanging device 3. The ineffective area is a portion where a display circuit or the like is not formed when the glass substrate 5 is finally processed into a flat panel display.
Therefore, even if wrinkles or dirt is attached to the ineffective area due to contact with the hanging device 3, a display circuit or the like is not formed in the ineffective area, which affects the quality of the flat panel display. There is no fear.

According to the packaging tool 1 described above, since the glass substrate 5 is suspended from the storage area 24 by the hanging device 3, the bottom surface 5b of the glass substrate 5 is in a floating state, and the weight of the glass substrate 5 is concentrated on the bottom surface 5b. There is no fear of doing. Thereby, damage to the glass substrate 5 is prevented. Further, since the storage area 24 is surrounded by the frame body 2, the suspended glass substrate 5 is protected by the frame body 2.
In addition, since the conveying tool 1 is provided with the linear members 4a and 4b as pressing members, there is no possibility that the glass substrate 5 protrudes from the accommodation region 24, and the glass substrate 5 can be prevented from being damaged.
Furthermore, according to said conveyance tool 1, the frames 21-23 which comprise the frame 2 can be disassembled, the frame 2 can be disassembled when the glass substrate 5 is not accommodated, and the storage space for the frame 2 Can be reduced.
Furthermore, said packing tool 1 is used suitably as a structural member of the packing container demonstrated below.

The packaging container 51 shown in FIGS. 6 and 7 is packed with a plurality of glass substrates 5, and the packaging body 61 is configured by the packaging container 51 and the glass substrate 5.

As shown in FIG. 7, the container main body 52 is configured by, for example, about 100 packing tools 1 being stacked in the thickness direction. Moreover, it is preferable that the stacking direction of the packing tool 1 is a horizontal direction or a direction slightly inclined from the horizontal direction in that the glass substrate 5 can be suspended and contact between the glass substrates 5 can be prevented.
Each packing tool 1 is integrated when the convex part 2c and the recessed part 2d provided in the frame 2 are mutually fitted. Moreover, when each packing tool 1 is integrated, each accommodation area | region 24 is piled up so that it may mutually communicate. As a result, the container body 52 is formed with a hollow portion 52 a formed by communicating the storage regions 24. And the glass substrate 5 is suspended in this hollow part 52a.

The container body 52 is provided with a pair of protective plates 53 and 53. The protection plates 53, 53 are mounted from both sides of the hollow portion 52a so as to close the hollow portion 52a of the container body 52. One protective plate 53a is provided with a concave portion 53b corresponding to the convex portion 2c of the frame body 2. The concave portion 53b and the convex portion 2c are fitted to each other so that the protective plate 53a is attached to the container body 52. Is done. Similarly, a convex portion 53d corresponding to the concave portion 2d of the frame body 2 is provided on the other protective plate 53c, and the convex portion 53d and the concave portion 2d are fitted to each other so that the protective plate 53c is attached to the container body. 52 is attached.

Further, the other protective plate 53c may not be provided with the convex portion 53d.
Further, as shown in FIG. 6, a fixing band 55 is attached to the container main body 52 and the protection plate 53. The container body 52 and the protection plate 53 are fixed to each other by the fixing band 55. The fixing band 55 is made of, for example, an elastic resin, rubber, polypropylene, etc., an inelastic resin, or the like. The protective plate 53 is made of, for example, a foamed resin.
Further, instead of the protective plate 53 and the fixing band 55, the overlapped frame body 2 may be wrapped and fixed with a wrapping film or the like.

The container body 52 and the protection plate 53 are placed on the pallet plate 54. A positioning projection 54a is provided on the pallet plate 54, and the positioning is performed on the pallet plate 54 with the container body 52 and the protection plate 53 engaged with the projection 54a. The pallet plate 54 is provided with an insertion hole 54b into which a fork such as a forklift can be inserted. In addition, it is not necessary to provide the hole which can insert forks, such as a forklift, in each packing tool 1, and to use the pallet board 54. FIG.
The container body 52 and the protection plate 53 are provided with a protective metal fitting 56 for protecting the corners. The protective metal fitting 56 is comprised from metal materials, such as aluminum, aluminum alloy, stainless steel, and SS.

Next, a method for packing the glass substrate 5 in the packing container 51 will be described. As shown in FIG. 8, a plurality of packing tools 1 are prepared, the wire 4 a and / or 4 b that is the pressing member 4 of each packing tool 1 is removed, and the glass substrate 5 is held by the hanging tool 3 of each packing tool 1. Then, the glass substrate 5 is suspended from the accommodation area 24. And the packing tool 1 is piled up along the thickness direction. When superposing, one protective plate 53 a may be placed on the pallet plate 54, and then the packing tool 1 may be superposed while being placed on the pallet plate 54. When all of the packing tools 1 are overlapped to form the container body 52, the other protective plate 53b is attached to the container body 52, and the fixing band 55 is further attached. Further, protective metal fittings 56 are attached to the corners of the container main body 52 and the protective plate 53. As described above, the packaging container 51 (packing body 61) is formed simultaneously with the packaging of the glass substrate 5. When the pallet plate 54 is not used, and when a notch is provided in a portion corresponding to the positioning projection 54 on the pallet plate 54 at the left and right corners of the lower side of the protective plate 53 so as not to interfere with the projection 54. A pair of protective plates 53 may be attached after the container body 52 is formed.
The formed packaging container 51 is suitably used for transporting the glass substrate 5.

Next, the unpacking method of said packing container 51 (packing body 61) is demonstrated. First, after removing the fixing band 55 and the protective metal fitting 56, one of the protective plates 53 is removed as shown in FIG. Thereby, the packing tool 1a to which the protective plate 53 is attached appears. This packing tool 1a is located on one end side in the stacking direction of the packing tool 1, and when the packing tool 1a appears, the glass substrate 5c suspended from the packing tool 1a also appears at the same time.
Next, as shown in FIG. 10, the glass substrate 5c is removed from the packing tool 1a. When removing the glass substrate 5c, the wire 4a or / and 4b as the pressing member 4 is removed while releasing the gripping state by the hanging device 3, and the glass substrate 5c is removed into the gap between the glass substrate 5c and the frame 2 A tool or the like is inserted and the glass substrate 5c is pulled out to the near side.
Next, as shown in FIG. 11, the packing tool 1a is removed. Thereby, the next packing tool 1b appears. Another glass substrate 5d is suspended from the packing tool 1b. Then, the glass substrate 5d and the packing tool 1b are sequentially removed. Thereafter, all the packed glass substrates 5 are taken out by repeating the same operation. The removed packing tool 1 is preferably disassembled for each of the frames 21 to 23 from the viewpoint of space saving.

As described above, according to the above-described packing container 51, the packing tools 1 are integrated into one container body 52 by superimposing a plurality of packing tools 1, and a plurality of packing tools 1 are formed inside the container body 52. Since the glass substrate 5 is suspended, it can be used as it is as a container for conveyance. Moreover, since the space | interval between glass substrates 5 can be narrowed, a storage rate is also raised.
Further, since the packing tool 1 is integrated while being fitted to each other, and the hollow portion 52a of the container body 52 is blocked by the protective plate 53, entry of foreign matter from outside is prevented, and the glass substrate 5 is contaminated with foreign matter or the like. There is nothing.

Further, the frame 2 constituting the packing tool 1 is provided with a convex part 2c and a concave part 2d, and the convex part 2c and the concave part 2d are fitted to each other to form the container body 52. There is no possibility that the container main body 52 is disassembled by shifting 1. Furthermore, since the container main body 52 and the protective plate 53 are fixed by the fixing band 55 and the protective metal fitting 56, there is no possibility that the container main body 52 is disassembled.
Since there is no possibility of disassembling the container main body 52 in this way, the packing container 51 itself can be loaded on a truck or the like and transported.
Moreover, since the rigidity of the container main body 52 improves by superimposing the packing tool 1, it can fully endure the packing of a glass substrate with a large size.

Further, since each packing tool 1 is provided with a pressing member that suppresses the shaking of the glass substrate 5, even if the packing container 51 being transported is shaken, the glass substrates 5 are in contact with each other and damaged. There is no fear.
Further, since the glass substrates 5 are suspended one by one at a predetermined interval, it is not necessary to interpose a protective sheet or protective paper between the glass substrates 5, and no packaging material such as a protective sheet is required. In addition, the glass is not easily soiled by paper dust or foreign matter.
Further, since the packaging tool 1 itself has a simple configuration, the weight of the transport container 51 can be reduced.

Moreover, according to said packing method, the glass substrate 5 can be easily attached to the packing tool 1, and after attaching the glass substrate 5 to the packing tool 1, it is necessary to touch the glass substrate 5 directly during packing operation. The glass substrate 5 can be prevented from being damaged or contaminated.
Moreover, according to said unpacking method, it is only necessary to remove the suspended glass substrate 5 and pull it out to the front, and the working efficiency can be greatly improved. Further, since the packing tool 1 from which the glass substrate 5 has been removed is sequentially disassembled and cleaned up, it is not necessary to secure a storage space, and space saving is achieved.
