Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate-shaped glass component carrying box which accommodates a plurality of plate-shaped glass components and protects them from vibration and shock during transportation.

[0002]

2. Description of the Related Art In recent years, with the development of electronic equipment, the development of peripheral technologies such as packaging and transportation thereof has been required. Plate-shaped glass parts used for liquid crystal panels and the like are thin and vulnerable to shocks, and are easily affected by external influences, making them difficult to handle. In particular, when the intermediate glass product is conveyed before it becomes a final product, the plate-shaped glass component is handled in an exposed state, so that it is affected by static electricity and dust.

Therefore, it is necessary to protect the plate-shaped glass parts during transportation, and conventionally, the plate-shaped glass parts have been packed using a carrier box as shown in FIGS. 8 and 9.

That is, the transport box 21 of this type has a transport box body 23 for accommodating a plurality of plate-shaped glass components 22, a lid 24 for covering the opening thereof, and a buffer for protecting the periphery of the plate-shaped glass components 22. And the body 25. Buffer 25
Is a lower buffer 25a that supports the plate-shaped glass component 22 from below at the bottom of the transport box body 23, and an upper buffer 25b that supports the plate-shaped glass component 22 from above at the top of the lid 24.
And side buffers 25c and 25d for laterally supporting the plate-shaped glass component 22 on both sides of the carrier box body 23, respectively.

A plurality of insertion grooves 26 are formed in the side buffers 25c and 25d, and the plate-shaped glass parts 22 are individually held in the insertion grooves 26 so that adjacent plate-shaped glass parts 22 are adjacent to each other. It is designed to be held so that they do not come into contact with each other. Therefore, the transport box 21 accommodates a plurality of plate-shaped glass components 22 in parallel at predetermined intervals, and the transport box main body 23
By fixing the lid 24 and the lid 24 with tape or the like, the buffer 2
5a, 25b, 25c, and 25d can protect the plate-shaped glass component 22 from vibration and shock during transportation and can transport it.

[0006]

By the way, in the conventional transport box 21, are the side buffers 25c and 25d having the plurality of insertion grooves 26 fixedly provided on both sides of the transport box main body 23? Alternatively, it was integrally formed with the transport box main body 23. Therefore, in order to store and convey the plate-shaped glass components 22 having different lengths, thicknesses, and the like, there is a problem in that a plurality of sizes of transport boxes 21 must be prepared for each of the dimensions.

Further, for example, the carrying box 21 designed for carrying a liquid crystal panel cannot be used for carrying other kinds of plate-like glass parts 22 such as a glass substrate on which electronic parts are mounted, and is therefore a general-purpose product. There was a problem of poor sex.

It is an object of the present invention to provide a plate-shaped glass component transfer box which can accommodate plate-shaped glass parts of different sizes and types and which is versatile.

[0009]

In order to achieve the above object,
The plate-shaped glass component transport box according to the present invention is a polyolefin bead foam molding having an L-shaped longitudinal section in a transport box main body that defines a storage space, and has a plurality of strips of glass along the inside thereof. A pair of cushioning bodies having a component insertion groove are detachably mounted, and a lid body that covers the opening of the transport box body is provided.

[0010]

According to the above construction, the pair of shock absorbers mounted in the main body of the transport box has an L-shaped longitudinal section, and a plurality of glass component insertion grooves are formed along the inside thereof. . By inserting the lower corners of the plate-shaped glass components into the glass component insertion grooves facing each other of the pair of buffer bodies, the plate-shaped glass components can be fixed in the air, and the contact between the adjacent plate-shaped glass components is prevented. Disturbed.

This buffer is detachably mounted in the main body of the transport box. Therefore, if you create a shock absorber according to the size and type of the plate-shaped glass part you are going to convey, you can transfer plate-like glass parts of different sizes and types by simply exchanging the shock absorber. It can be transported in a box and is highly versatile.

Further, since the liquid crystal panel, the glass substrate on which the electronic parts are mounted, or the like is provided with a high-performance function or is transported in the provided state, the buffer body is subjected to strict quality control before use. Must be maintained. Therefore, the buffer body is required to have chemical resistance to the cleaning liquid and not to generate dust.

In the present invention, at least the cushioning body is the polyolefin bead foam molding, so that even if a shock such as repeated cutting by a sharp portion such as a cut surface of the glass plate is received, the above-mentioned shock is caused by the flexibility of the polyolefin. In addition, the generation of dust is remarkably small due to the large thickness of the skin, which is the most characteristic feature of the beads. In polystyrene resin (eg EPS) beads, polystyrene-polyethylene copolymer resin foam, etc. that are commonly used, dust is often generated due to the rigidity peculiar to the resin during transportation,
Damage occurs to the glass plate parts. Further, since polyolefin has excellent chemical resistance, it can withstand washing and can be sufficiently adapted for repeated use.
