Description

  The present invention is capable of packing a glass substrate for a large-sized liquid crystal display having a film surface such as a color filter, which can be safely and compactly packed and transported, and is also affected by particles, moisture, and organic substances during transportation and storage. In particular, the present invention relates to a glass substrate packaging method using a vacuum pack and a package thereof.

  Conventionally, when packing and transporting a glass substrate for liquid crystal display or the like, a polypropylene foam case, a resin case, or the like is used depending on the application. This method is mainly used for packing and transporting glass substrates up to over 1m in length, which is said to be the fifth generation, and is excellent in transportability, but the distance between the glass substrates in the case is about 20mm. There is a limit to the number of items that can be stored inside and the number of items that can be transported by truck, etc., and returning empty cases has been an inefficient method.

  In consideration of the above phenomenon, a method has been proposed in which a box body having a hollow portion partitioned by ribs and a lid are hermetically packaged with a sealing material (see, for example, Patent Document 1).

  Furthermore, a method of sealing and sealing a sheet material such as a glass substrate by sandwiching the front and back of each sheet between two protective films has been proposed (for example, see Patent Document 2).

  In Patent Document 1, a glass plate is stood and stored in a box having a plurality of hollow portions partitioned by ribs, and a gap between the lid and the lid is sealed with an elastic sealing material and fixed with a fastener. However, since the box has an interval between the substrates as in the conventional foam case, it is not suitable for compact packaging, and it has been difficult to keep the inside of the box always clean.

  Next, since the means described in Patent Document 2 sandwiches each plate material with a protective film, the amount of the protective film used is enormous, and it is difficult to make the packaging form compact.

The known literature is shown below.

  According to the present invention, the packing method further improves the sealing property of the vacuum pack and increases the film strength when vacuum packing a large number of glass substrates at the same time, thereby affecting the influence of particles, moisture, and organic matter during storage. It is a packing method to prevent

  In the invention according to claim 4 of the present invention, the packing body is formed on a glass substrate, and after packing a protective sheet between the glass substrate film surface side and the glass substrate back surface side of the next glass substrate The glass substrate packaging method according to any one of claims 1 to 3, wherein a vacuum packing is performed using a laminate film for each packaging body.

  The invention according to claim 5 of the present invention is a glass substrate package characterized by being packed using the glass substrate packing method according to any one of claims 1 to 4.

  The invention according to claim 6 of the present invention is characterized in that the glass substrate is laid in the vertical direction and is packed in a certain number of glass substrates. This is a method for packing a glass substrate.

  According to the present invention, when a glass substrate for a large liquid crystal display on which a film surface such as a color filter is formed is erected, the glass substrate is scratched or damaged when the glass substrate is stacked in a horizontal direction. Provided is a packaging method for preventing and preventing the influence of particles, moisture, and organic substances during transportation and storage, and is a packaging method in which a large number of sheets are vacuum packed together.

  The invention according to claim 7 of the present invention is a glass substrate package characterized by being packed using the glass substrate packing method according to claim 6.

  According to the present invention, a packaging method for preventing scratches and damages on the glass substrate film surface side and vacuum-packing a large number of sheets at once, and preventing the influence of particles, moisture and organic matter during transportation and storage And provide a method for its transportation.

  In the packing method that vacuum-packs the glass substrate in the horizontal direction with the glass substrate for large liquid crystal display formed with a film surface such as a color filter, the volume is greatly reduced compared to the conventional packing method, The number of packages can be increased approximately 15 to 25 times with respect to the same packing volume.

  In the packing method of the present invention, it is confirmed that vacuum packing can be performed in a lump after stacking 600 glass substrates.

Further, in the packaging method of the present invention, after 600 glass substrates are stacked, in a vibration test with a package that is vacuum-packed in a lump, the effect on the glass substrate, film surface, scratches, It has been confirmed that no damage occurs.

  As an application example of the present invention, it can be widely used for glass without a film surface other than a glass substrate for liquid crystal display with a film surface, and other thin glass, including a package by a conventional glass substrate packaging method.

  The glass substrate packaging method of the present invention will be described in detail with reference to the drawings along the embodiment. FIG. 1 is a side sectional view showing an embodiment of the present invention.

  In addition, this method is advantageous for packing and transporting a large glass substrate having a glass size exceeding 1 m, and a glass substrate for a liquid crystal display having a film surface formed thereon, for example, a 6th generation or a 7th generation glass substrate with a larger size. It is suitable for size color filters.

  As shown in FIG. 1, the glass substrate 1 has a protective sheet sandwiched between adjacent glass substrates, forms a package 10, performs a vacuum pack 3 in a lump, and then seals positions 4 after packaging. The vacuum pack 3 is decompressed, the inside of the vacuum pack 3 is set to a predetermined pressure, the seal position 4 after packing is closed, and packing of the vacuum pack 3 is completed. The glass substrate is stored in an upright state. At this time, the glass substrate film surface side 5 and the protective sheet 2 are not damaged in order to prevent damage to the glass substrate film surface side 5 due to vibration during transportation. Make contact so that no gap is generated. The packing body 10 is a package in which a predetermined number of glass substrates are packed using a predetermined packing material according to a predetermined procedure, and is at least one. The packing body 10 in the present invention is packed by a conventional packing method or the packing method of the present invention, and includes, for example, a packing in a resin case or the like.

  FIG. 2 is a side sectional view showing an embodiment of the present invention. The package 10 of the protective sheet 2 and the glass substrate 1 is further covered with two upper and lower laminate films, and only the both end portions of the laminate film are sealed together, and then a seal position 4 after packing. In this method, the vacuum pack 3 is melted by heating and cut off from the atmosphere. The internal pressure of the vacuum pack 3 is equal to that of the atmosphere, or is vacuum packed in a state where the pressure is slightly reduced.

  In addition, the glass substrate after the vacuum packing is fixed in the front / rear, left / right, and upper / lower directions, and is sufficiently fixed so that the glass substrates are not rubbed with each other due to vibration during transportation. At this time, it is assumed that the strength of the lower surface of the packaging case has a strength that can sufficiently exceed the weight of the total number of glass substrates.

  Next, the packaging body is hermetically packaged with the exterior packaging material to complete the packaging body of the glass substrate. The glass substrate package prevents contamination from the outside during storage and transportation. As the exterior packaging material, it is preferable to select and use a clean material that does not generate dust and gas.
