This invention relates to the conveyance box for arranging, storing, and conveying a plurality of glass substrates in parallel in an upright position.

Production and sales of flat panel displays (FPD), such as plasma display panels (PDPs) and liquid crystal monitors (LCDs), are being actively activated in response to the demands of the times such as the increase in the size of an image display and the reduction of the weight and the like. The glass substrate used for production of FPD is accommodated in a conveyance box in the state arrange | positioned in parallel by making multiple sets into one set. Then, it is conveyed from the glass substrate manufacturing plant or the like to the production plant of the display panel or the like, the glass substrates are taken out one by one from the box and transferred to the production line of the panel or the like.

In the production line of a panel, many lines were designed on the premise that the glass substrate is taken out from the parallel arrangement of several glass substrates, and as a result, it is standard that a conveyance box respond | corresponds to the said line design. It is. In addition, since the glass substrate must be maintained at a high degree of cleanliness so as to cope with the production of FPD, and it is necessary to be stored and held so that no damage such as cracks occurs at the time of conveyance, it is proposed that the transport box has a special structure. It is.

For example, in Patent Document 1, a bottomed box made of a foamed resin molded body is fixedly installed on an upper surface of a base forming a bottom surface, and a plurality of glass plates are placed inside the box body. Assembling an L-shaped pad made up of a side plate portion and a bottom plate portion having a holding groove for holding, and covering the upper opening of the box with a lid, and between the lid and the lid side of the glass substrate end face. The conveyance box in which the pad was arrange | positioned in between is disclosed. In addition, Patent Document 2 discloses a transfer box having a structure in which the positioning of the pad can be accurately and easily performed and the position change of the pad can be easily changed.

In order to mass-produce FPD, the production method of the multifaceted odor which produces two or more panels collectively on a large-area glass substrate has become mainstream. In the production method of a polyhedron, the glass substrate for a polyhedron requires the glass substrate of the area according to it. For example, if a 42-inch panel shifts from four chamfers to six chamfers, a glass substrate with a large area of about 1 m 2 is required. Moreover, in 50 and 60 inch size, even if it is two chamfers, it becomes necessary to hold the glass substrate of the height of 1-2 m, and accordingly, a conveyance box also needs to be high. This brings about the necessity of the new conveyance box corresponding to the glass substrate of a large area.

The conveyance of a plurality of glass substrates becomes the conveyance of a heavy object. When a glass substrate becomes large, the weight becomes that much, and load resistance is calculated | required suitably also for a conveyance box. On the other hand, since the glass substrate is also a brittle material, it must be sufficiently protected from the impact from the surroundings during conveyance.

When arranging a plurality of glass substrates in parallel in an upright posture and storing them in a transport box, in consideration of protecting the glass substrate from impact or the like between the glass substrate and the transport box, the wall surface of the glass substrate and the transport box It is preferable that there is a certain space between and.

This is connected to providing the space | interval between the holding pad arrange | positioned at the side surface which a glass end surface part faces, ie, the holding pad which holds the cross section of the glass substrate of an upright attitude | position, and the wall surface of a conveyance box. However, since the glass substrate to be conveyed is a heavy object, a large load is applied to the holding pad at the time of conveyance, and even if the holding pad is fixed to the bottom surface of the conveying box with a screw or the like, position shift of the holding pad occurs, and the glass An abnormality occurs in the positional accuracy of the substrate. The said position precision is an important matter at the time of taking out of a glass substrate. And in a worst case, a glass substrate may come out of a holding pad, and damage, a crack, etc. may arise in a glass substrate.

In patent documents 1 and 2, the structure which introduces a spacer between the holding pad which hold | maintains the cross section of the glass substrate of an upright attitude | position, and the wall surface of a conveyance box is disclosed, and patent document 2 is a material of a spacer A resin foamed molded article is disclosed.

The presence of these spacers is effective in eliminating the large deviation of the holding pads holding the cross section of the glass substrate in the upright posture, but the positional accuracy of the glass substrate is improved when the glass substrate becomes a large object and becomes a heavy object. It becomes difficult to hold. Therefore, in this invention, let it be a 1st subject to provide the conveyance box for glass substrates provided with the spacer which has a structure in which the position shift of the holding pad which hold | maintains the cross section of the glass substrate of an upright attitude | position is hard to produce.

Moreover, when a glass substrate becomes large, distortion will generate | occur | produce easily, and the deviation of the glass substrate at the time of conveyance will become easy to occur. In order to prevent the contact of glass substrates, when the space | interval which arranges a glass substrate in parallel is widened, the conveyance efficiency will fall. And since the large area of a glass substrate brings about weight increase, it is necessary to lighten the member used for a conveyance box in order to improve transportation efficiency, but such a measure brings about the fall of the strength of a conveyance box.

Moreover, since the large area of a glass substrate results in a structure with a high height in a conveyance box, when taking out a glass substrate, the buffer member provided between a glass substrate and the cover body of a conveyance box can be taken out efficiently. There is a need for a structure that makes it possible to exist.

Thus, this invention aims at solving these problems, and it is not necessary to make the space | interval at the time of arrange | positioning a glass substrate in parallel more than necessary, and even if a lightweight box is selected and a conveyance box is formed, it is strength.
