Description of the Invention: [Technical Field] The present invention relates to a glass packing structure and a glass packing method, and more particularly to a glass packing structure and a glass packing which bundles glass in a laminated state. method. [Prior Art] For example, a glass substrate used in a liquid crystal display device or the like is manufactured in a glass factory, and then loaded into a truck or the like and transported to a display panel. Therefore, the glass substrate is inserted between the glass substrates. The cushioning material is bundled so as not to damage the accumulation level (main plane) during transportation. In the conventional glass packing structure, for example, when each glass substrate is laminated by a transfer robot, a sheet-shaped cushioning material having a larger area than the glass substrate is inserted between the glass substrates to form a layer of each glass substrate. The packaging is carried out without contacting each other (for example, refer to the patent document 丨). As the cushioning material, paper (spacer paper) or a resin film or the like is used, which is placed one by one on each of the glass substrates when the glass substrates are laminated, and the next glass substrate is laminated thereon. In recent years, the glass substrate has been manufactured to have a large area called the eighth generation size, and the long side X short side of the 8th generation glass substrate is 2.5 mx2 2 _24 (four) 2" m. Further, as the size of the glass substrate is increased, the cushioning material interposed between the respective glass substrates of the laminate is also increased in size. [Problems to be Solved by the Invention] However, the packaging of each of the glass substrates which have been laminated and enlarged as described above is carried out. In the step, the buffer material inserted between the layers of the glass substrates is enlarged, and the operation of the cushioning material on the glass substrate is difficult. For example, there is a problem that it is difficult to move the cushioning material in such a manner that it does not wrinkle or bend. Further, with the increase in the size of the cushioning material, there is also a problem that the manufacturing cost of the cushioning material becomes more expensive. As a method for solving the above problems, it has been studied to insert a plurality of cushioning materials formed to have a smaller size than a glass substrate between glass substrates. However, in this method, there is a problem that the stress is concentrated on the end portion (edge) of the cushioning material, that is, the so-called edge effect, which damages the laminated layer of the glass substrate; or the constituent component of the cushioning material is The contamination adheres to the glass substrate and is difficult to remove. In particular, if the ends of the cushioning material overlap each other, the above problem is more remarkable. Further, if the distance between the end portions of the cushioning material is large, the laminated glass substrate is pressed against the corner portion of the end portion of the cushioning material by its own weight, causing damage due to the edge effect as described above or In addition to this problem, there is a problem that the glass substrates are in direct contact with each other and are damaged. Therefore, the present invention has been made in view of the above circumstances, and an object of the invention is to provide a glass packing structure and a glass packing method which solve the above problems. In other words, it is an object of the present invention to provide a structure and a glass package for laminating glass 157407.doc 201217238 without the increase in the size of the cushioning material and the deterioration of the quality of the glass even when the glass is enlarged. method.

The above direction is formed by forming an inclined surface or a curved surface in advance. (12) The materials of the respective cushioning materials are offset from each other (4) in such a manner that the layers of the adjacent glass sheets are formed at different positions. Advantageous Effects of Invention According to the present invention, a plurality of cushioning materials having an area smaller than a layer of glass are inserted between the layers of the respective glass, and the ends of the plurality of cushioning materials are not overlapped so that the phases are close to each other. Since the interval between the end portions of the adjacent cushioning materials is equal to or less than a specific value, the shirt overlaps the portions of the plurality of cushioning materials to form the surface (four) of the glass, and the cushioning material becomes smaller due to the surface of the cushioning material. When the glass is placed on the surface of the glass, the cushioning material is wrinkled and can be efficiently packed. [Embodiment] The following is a description of the embodiment 1 for carrying out the invention with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a view showing the self-contained structure of the glass of the present invention. Fig. 2 is a view from the top of the room. + A see the example before the case. The glass-packed structure of the present invention is shown above. In the step of laminating the glass substrate 20 formed into a specific size (for example, the eighth generation size) by the transfer robot, the buffer material is at least 2 pieces in the following steps: 157407.doc 201217238 Inserted between the layers of the respective glass substrates 20. Further, in the cushioning material 3, the contact area with the glass of the cushioning material 3 is smaller than the area of the contact area (main plane) of the glass substrate 2A. In the present invention, the contact area of the cushioning material 3〇 may be arbitrary. The right side is, for example, a glass having a long side A mm and a short side b mm, and the contact size of the cushioning material 30 with the glass substrate 20 is determined to be any size of A mm or less and B mm or less depending on the number of n of the cushioning material. Just fine. It is assumed that the contact size when using two buffer plates is preferably a long side 〇·5Α mm or less and a short side B mm or less, and may be set to a long side A mm or less and a short side 〇 5B claw lower. The cushioning material 30 is formed of sheet-like paper (spacer paper) or a resin film which is formed to have a small thickness (for example, thickness = 〇 〇 5 〇 mm to 0.095 mm). Further, since at least one of the long side or the short side of the cushioning material 30 is about half the length of the previous cushioning material, wrinkles are less likely to occur, the operability is improved, the packing operation is simplified, and the cost is also suppressed. cheap. Moreover, when the two cushioning materials 30 are disposed adjacent to each other between the layers of the glass substrate 2, the distance between the end portions 32 of the cushioning members 30 is fixed in parallel, and the cushioning material 3 is used. The peripheral portion of the crucible is disposed to protrude more than the outer periphery of the glass substrate 20. Further, in order to prevent the end portions 32 of the adjacent two cushioning members 30 from overlapping each other at the central portion of the glass substrate 2, the distance s between the end portions 32 of the respective cushioning members 30 becomes 〇mm or more and 2〇mma. The way to set. Here, the setting conditions of the interval S between the buffer members 30 and the end portions 32 of the respective cushioning materials 3A will be described. 157407.doc -8 - 201217238 Close buffer material 3. With the setting condition of the interval s, when the plural pieces are buffered in m", the thickness is set to the number of the ... the number of the coffee materials and the integer is 2 or more, and the arithmetic mean value of the thickness of the n-sheet cushioning material is set to tave. The plurality of sheets 蝼<, the maximum value of the thickness ti~tn of the slap buffer material is not tmax, and the minimum value is set to) t. When tmin is again, both (B) and V are satisfied at the same time; [5] |tmax-tave| $ 〇.12xtave...(A) [Number 6] |tave-tmi„| ^ 〇.12xtave. . . . (B) and the distance s between the end portions 32 of the adjacent buffer materials 30 becomes 〇~2〇mm. Here, if the coefficient of the side of t is larger than 〇12, the paper with the thickest paper thickness protrudes. Focusing on the edge portion, it is difficult to remove the contamination 4 On the one hand, 'If the coefficient on the tmin side is larger than 〇·12, the pressure is concentrated on the edge of the paper adjacent to the thinnest paper' so that it is difficult to remove the contamination. According to the condition, the buffer materials can be placed on the layer of the glass substrate 20 in such a manner that the end portions 32 of the adjacent buffer materials 30 are not separated as needed. Therefore, the laminated glass substrate 2 is provided. In the step of arranging, the load of the glass substrate 20 of the upper stage is dispersed on the plane of each of the buffer materials, thereby preventing damage or contamination of the accumulated layer contacted by the end portion 32 of the cushioning material 3 in the glass substrate 20. Further, it is possible to prevent the glass substrates from coming into contact with each other. Further, it is preferable that the buffer material 3 which is in contact with the glass substrate 20 is 157407.doc 2 01217238 The thickness measured at the front end of the end portion 32 is thin. For example, the front end is thinned by adding 3 2 to the front end of the cushioning material 30 by using a roller or the like based on JIS P 8118. II can be made thin by the front end of the end portion 32 of the cushioning material 3 上述. The load of the glass substrate 20 that is in contact with is concentrated on the end portion of the cushioning material %. Next, a modification will be described. [Modification 1] A longitudinal sectional view of an end portion of a cushioning material. Fig. 4A is an enlarged view showing a modification. Fig. 4B is an enlarged longitudinal sectional view showing a state in which a modification is made. (4) As shown in FIG. 4A, the end portion 32a of the cushioning material 3Ga is formed by a surface 36a which is bent in a direction of 90 or more with respect to the contact surface "a" which is in contact with the glass substrate 2 by grinding or press working, etc., as shown in Fig. 4B. As shown in the step of laminating the glass substrate 2, the two buffer materials 30a are disposed on the glass substrate 20 with the end portions 32a interposed therebetween at a predetermined interval s. As a result, the cushioning material 3 is used. Since the end portion 32a of the crucible a is formed with the curved surface 36a, the load of the glass substrate 20 is not concentrated on the corner portion 'of the end portion 32a of the cushioning material 3a, and is dispersed in the curved surface 36a of each of the cushioning members 3a. The damage or contamination of the glass substrate 20 in contact with the end portion 32a of the buffer material 30a in the glass substrate 20 is prevented from adhering to the glass substrate 20. In the buffer material 30a, the setting conditions also satisfy the formulas (A) and (B). Further, the setting is made by the method of 157407.doc •10-201217238 in which the distance S between the adjacent buffer materials 30a is 90 to 20 mm. [Modification 2] FIG. 5A is an enlarged view showing the cushioning material of the modification 2. A longitudinal section of the end portion. Fig. 5B is an enlarged view showing the cushioning material of the second modification. A longitudinal section of the state between the layers of the glass. As shown in Fig. 5A, the end portion 32b of the cushioning material 30b is provided with a chamfer 36b at the corner. The chamfer 36b is formed by grinding or pressing. It is formed so as to be inclined at an angle α (α=90 or more) with respect to the contact surface 34b in contact with the glass substrate 20. As shown in FIG. 5A, in the step of laminating the glass substrate 2, two cushioning materials are used. 30b is disposed on the glass substrate 20 so that the end portion 32b is opposed to each other with a predetermined interval S. As a result, since the chamfer 36b is provided at the corner portion of the end portion 32b of the cushioning material 3b, the glass substrate is provided. The load of 2〇 is not concentrated on the corner portion 'b of the end portion 32b of the cushioning material 3〇b, and is dispersed in the chamfer 36b of each cushioning material 3〇b. Thereby, the buffer material 3 〇b in the glass substrate 2〇 is prevented. The damage or contamination of the glass substrate 20 contacted by the end portion 32b adheres to the glass substrate 2. In the buffer material 30b, the setting conditions also satisfy the formulas (A) and (B), and the adjacent buffer materials 30b The distance between the end portions 32b is set to 0 to 20 mm. [Modification 3] Fig. 6A is an enlarged table Fig. 6B is a longitudinal cross-sectional view showing a state in which the cushioning material of the third modification is inserted between the layers of the glass. I57407.doc -11 - 201217238 As shown in Fig. 6A, the end portion 32c of the cushioning material 30c is provided with an inclined surface 36c. The inclined surface 36c is angled by a grinding or pressing process or the like toward an contact surface 34c with respect to the glass substrate 20 (α = 9). 〇. The above direction is formed by tilting the direction. As shown in Fig. 6A, in the step of laminating the glass substrate 20, the two cushion members 30c are disposed on the glass substrate 20 so as to face each other with a predetermined interval s therebetween. As a result of the above, since the inclined surface 36c is provided at the end portion 32c of the cushioning material 30c, the load of the glass substrate 2 is not concentrated on the corner portion of the end portion 32c of the cushioning material 3〇c, but is dispersed in each cushioning material. The plane of the 3〇c and the inclined surface 36c prevent the adhesion or contamination of the glass substrate 20 which is contacted by the end portion 32c of the cushioning material 3〇c in the glass substrate 20 to the glass substrate 2〇. In the cushioning material 30c, the setting conditions satisfy both the formulas (A) and (B), and the distance s between the tips of the inclined surfaces 36c of the adjacent cushioning members 30c is set to 0 to 20 mm. [Modification 4] Fig. 7A is an enlarged longitudinal sectional view showing an end portion of a cushioning material according to a modification 4. Fig. 7B is an enlarged longitudinal sectional view showing a state in which the cushioning material of the fourth modification is inserted between the layers of the glass. As shown in Fig. 7A, the end portion 32d of the cushioning material 3〇d is provided with a jade inclined surface 36d and a second inclined surface 38d. The first inclined surface 36d and the second inclined surface 38d are inclined in a direction of an angle α (α=90 or more) with respect to the contact surface 34d that is in contact with the glass substrate 2〇 by polishing or press working, respectively. form. As shown in Fig. 7A, in the step of laminating the glass substrate 2, two sheets of buffer 157407.doc 12 201217238 material 30d are placed on the glass substrate 20 so that the end portions 36d face each other. As a result of the above, since the first inclined surface 36d and the second inclined surface 38d are provided at the end portion 32d of the cushioning material 30d, the load of the glass substrate 20 is not concentrated on the corner portion of the end portion 32d of the cushioning material 30d. The first inclined surface 36d and the second inclined surface 38d are dispersed in the respective cushioning materials 3〇d. Thereby, damage or contamination of the glass substrate 2 which is in contact with the end portion 32d of the cushioning material 3?d in the glass substrate 20 is prevented from adhering to the glass substrate 20. In the cushioning material 30d, the setting conditions are also satisfied, and the distance S between the first inclined surface 36d and the second inclined surface 38d of the adjacent cushioning material 30b is set to 0 to 20 mm. In order to process the end portions 32a to 32d of the cushioning materials 3a to 3d, as in the above-described Modifications 1 to 4, a method of crushing the end portions 32a to 32d by a pressing member such as a roller is exemplified. Or a method of cutting the cutting by a cutting jig (a cutter or the like). Further, when the cushioning members 30a to 30d are plastic films, the end portions 32a to 32d may be curved by heating and expansion.

The area of each of the cushioning materials 30e and 30f is, for example, the short side length 157407.doc 201217238 of the first cushioning material 30f. When the short side length L1 of the first cushioning material 30e is arranged, two cushioning materials 3〇e and 30f are arranged. The total width dimension l is equal to or less than half (LIS L/2), and the second cushioning material 3 (the short side length 1^2 of ^ is one half or more of the above 1^ (1^2 2 1^/2) is cut. Further, the difference between 'L1 and L2' is preferably 1 mm or more, more preferably 20 mm or more, and still more preferably 40 mm or more.
