Description

  The present invention relates to a frame for transporting a plate glass, a glass substrate and a color filter substrate used in a liquid crystal display device which is a processed product thereof.

Conventionally, when storing and transporting a color filter substrate on which projections such as a black matrix, a colored layer, a transparent conductive film layer and a spacer are formed on the surface of a glass substrate which is a plate glass, a glass substrate and its processed product, In order to protect the glass substrate from scratches and breakage, a box-shaped storage container that can store the glass substrates in parallel at a predetermined interval is used so that the glass substrates do not contact each other.

  However, recently, manufacture of large glass substrates has been required, and if these are stored at predetermined intervals in a box-shaped storage container as in the past, a larger storage container and storage space are required, There has been a problem that the glass substrate edge is damaged by coming off from the groove due to vibration during transportation or buckling due to its own weight, resulting in contact with the adjacent glass substrate in the box.

  The present invention protects processed products such as large glass plates, glass substrates and color filter substrates from scratches and damage during transportation, and provides a platform that is advantageous for transporting processed products such as large glass plates, glass substrates and color filter substrates. It is to provide.

  The present invention can be attached to a floor member, a pressurizing body capable of pressing the object to be transported loaded on the floor member toward the floor member, the floor member, and an end of the object to be transported. An enclosure member provided on the side of the floor member and the pressure body that supports the object to be conveyed, and a honeycomb panel that supports the entire surface of the object to be conveyed. Is a gantry characterized in that it has an upper surface member that faces the floor member and pressurizes the entire surface of the object to be conveyed.

  The gantry of the present invention is equipped with a large number of large glass plates, glass substrates or processed products thereof, and can support and transport the entire surface of the glass substrate uniformly. Can be prevented from rubbing between the substrate and the separation body, the conveyance efficiency is good, and damages such as scratches and defects on the substrate surface can be avoided.

Embodiments of the present invention will be described below with reference to the drawings.

It is preferable from the viewpoint of work that the enclosure member 11 is easily connected and detached. For example, as shown in FIG. 5, a hole 25 is provided in the floor member 3, and a hook 27 that engages with the hole 25 is provided in the surrounding member 11, and the hook 27 is engaged with the hole 25 as shown in FIG. Then, the enclosure member 11 is connected to the floor member 3. The enclosing member 11 is provided avoiding the corners of the glass substrate 21. The enclosing member 9 has a rectangular frame shape.

  It is preferable to provide rubber 17 on the surfaces of the supporting member 7 and the enclosing member 11 that are in contact with the ends of the glass substrate 21. Thereby, the impact at the time of transportation and the irregularity of the glass substrate 21 can be absorbed. The rubber preferably has a thickness of 3 mm to 10 mm and a hardness of 30 HS to 70 HS.

  Honeycomb panels 13 and 15 are disposed on the support surface of the floor member 3 and the glass substrate 21 of the pressurized body, respectively. In the present invention, it is particularly important to sandwich the glass substrate 21 with a surface that is difficult to bend, and the honeycomb panel is less likely to be twisted or bent, and the glass substrate 21 is supported on the entire surface and is pressed with a partial bias. Can be prevented. The thickness of the honeycomb panel is not particularly limited, but is preferably 50 mm or less.

  The glass substrate 21 is a plate glass, a glass substrate and a processed product thereof, and a color filter substrate and a color filter substrate provided with a protective layer on the surface can also be used. The glass substrate 21 is not particularly limited in size, but can be suitably used as a substrate having a length of each side of 0.5 m to 2.5 m. Further, the number of stored sheets is preferably about 1 to 500. When the glass substrate 21 is mounted on the gantry, it is preferable to use a separating body made of paper, a resin film, a sponge sheet or the like between the adjacent glass substrates 21 in order to avoid contact between the glass substrates 21.
