The present invention relates to a shock absorbing material for packaging a glass substrate, and more particularly, the glass substrate, such as PDP or LCD, plate-shaped finished products or intermediate products such as TFT-LCD, vertically standing vertically, without contact with each other When carrying or storing, the present invention relates to a cushioning material for packaging a glass substrate for protecting the substrate from vibrations or external shocks during transportation to prevent breakage.

Conventionally, a cushioning material such as corrugated cardboard or styrofoam is used to support only the edge portion of the substrate when transporting such a glass substrate, a plate-shaped finished product, or an intermediate product. There were a lot of difficulties, and there was a problem such as increase in logistics costs because a new packaging buffer must be used every time because the packaging buffer could not be used repeatedly. Therefore, in recent years, a technology such as Utility Model Registration No. 20-281102 or No. 20-296095 has appeared as a buffer box or a packaging aid device.

However, in the technique as described in Utility Model Registration No. 20-281102 in Fig. 1, the projections 24 and the glass substrate insertion grooves 26 are formed vertically, so that the size suitable for the thickness of the glass substrate or the plate-shaped product There had to be a variety of packaging cushioning materials with glass substrate slot widths. In addition, since the protrusions 24 and the glass substrate insertion grooves 26 are formed only in the vertical buffer material 22, the protrusions 24 and the glass substrate insertion grooves 26 are not formed in the horizontal buffer material 20. Not only can not be firmly fixed when transporting the plate-shaped product, but also because no groove is formed on the back side formed with the projection and the glass substrate insertion groove, it is difficult to fix the packing buffer 18 to the transport box or container, Since irregularities are formed only on one surface during processing, many problems are exposed, such as deformation due to heat during manufacturing.

In addition, in the case of Utility Model Registration No. 20-296095, a single buffer box cannot carry a large amount of glass substrates or plate-shaped products at one time, and the structure of the buffer box is complicated, and There are many problems, such as the need to prepare a variety of buffer box depending on the size.

The present invention has been made in order to solve the above problems, the present invention is not only normal glass, but also glass substrates such as PDP or LCD, plate-shaped finished products or intermediate products such as TFT-LCD vertically transported without contact with each other The purpose of the present invention is to provide a shock absorbing material for packaging a glass substrate, which can protect the substrate from vibrations or external shocks generated during transportation, to prevent damage, and can be used semi-permanently, thereby reducing logistics costs.

Still another object of the present invention is to provide a shock absorbing material that can be used to connect a plurality of shock absorbers or to combine different types of shock absorbers when transporting and storing a large glass substrate.

In addition, the present invention uses a foamed resin material because there is a problem such as damage to the corrugated cardboard, which was conventionally used as a cushioning material for packaging, cannot be reused, and dust is generated. As a foamed resin material, non-crosslinked EPE (LLDEP system) and EPP (Expanded Polypropylene) are generally excellent in cushioning, flexibility, and chemical resistance, which can improve packaging stability and reduce packaging volume. Normally, EPE is relatively soft and is used as a cushioning material for lightweight products, while EPP has a relatively hard and brittle property but high strength. In the present invention, by using the EPP in forming the substrate, as well as physical properties such as impact resistance compared to corrugated cardboard or general styrofoam, moldability and dimensional stability are good and repeated use is possible, thereby securing economical efficiency.

The present invention is formed along the height direction of the cushioning material and the glass substrate insertion grooves alternately at regular intervals on one surface in order to achieve the above object, the rear of the plurality of between the fixture insertion groove and the fixture insertion groove The thin groove is formed in the same direction as the projection, the shape of one end portion of the glass substrate insertion groove is formed so that the width of the insertion groove is wider toward the opening, the shape of one end portion of the projection is also lower toward the outside The packaging cushioning material of the glass substrate comprised by the inclination to make it is a structural feature.

Preferably, the package cushioning material for glass substrates is characterized in that the cross-sectional shape of the projections formed on the cushioning material is rectangular or trapezoidal.

Preferably, the horizontal buffer member is formed alternately on the upper surface of the projection and the glass substrate insertion groove, and vertically placed in an L-shape at one end of the horizontal buffer member, formed in the horizontal buffer member Similarly to the projection and the glass substrate insertion groove, the shape of the vertical buffer material having alternately formed projections and the glass substrate insertion groove, and the one end portion of the projection formed on the horizontal buffer material and the vertical buffer material are inclined so as to lower toward the outside. The packaging cushioning material of a glass substrate is a structural feature.

Preferably, the vertical length of the vertical buffer material is characterized in that the packaging buffer of the glass substrate, characterized in that longer than the horizontal length of the horizontal buffer material.

Preferably, the two buffers formed by alternating protrusions and the glass substrate insertion grooves at regular intervals on one surface, a buffer connecting portion connecting the two buffers at regular intervals, and the one at least one of the two buffers at regular intervals. The shock absorbing material is formed of a cushioning material connecting protrusion formed on the cushioning material connecting part, and the two cushioning material on the cushioning material connecting part and the shock absorbing material for packaging the glass substrate are characterized in that the molded part is integrally molded.

Hereinafter will be described in detail with reference to Figures 2 to 8 with respect to the configuration and operation of the buffer for packaging of the glass substrate according to the present invention.

Figure 2 is a perspective view showing a state of use of the packaging cushioning material according to the present invention, Figures 3 to 7 shows a first embodiment, Figure 8 shows a second embodiment, Figure 9 shows a third embodiment An example is shown.

3 to 7 are views showing a first embodiment of the present invention, in which a projection 34 and a glass substrate insertion groove 36 are alternately formed on one surface thereof, and three fasteners are inserted on the rear surface thereof. A plurality of thin grooves 38 are formed in the same direction as the protrusions 34 between the grooves 39 and the fixture insertion grooves 39, and in detail, one end of the glass substrate insertion grooves 36 ( The shape of the part is formed so that the width of the insertion groove becomes wider toward the opening (see 36 '), and the glass formed by being inclined so as to lower the shape of one end of the part of the protrusion 34 toward the outside (see 34'). A buffer material 30 for packaging a substrate. Of course, the number of the fixture insertion groove 39 or the thin groove 38 may be formed by changing the number as necessary.

When the glass substrate or the plate-shaped product is inserted into the packaging buffer for transporting or storing the product, the glass substrate insertion groove 36 is formed by inserting the glass substrate from a wide portion at one end of the glass substrate insertion groove 36. Guided by the protrusions 34 serving as the side wall of the c) is partitioned and wrapped one by one so that the glass substrates do not come into contact with each other, and is safe even from vibrations or external shocks generated during transportation.

Here, as shown in FIG. 5, the wide width of the insertion groove is formed at one end of the glass substrate insertion groove 36 so as to smoothly insert the glass substrate when the glass substrate is inserted into the packaging buffer material, and the protrusions 34 may be used. The one end portion of the glass is also formed to be inclined when the glass substrate is inserted and removed. In other words, since the width of the insertion groove widens near the opening of the glass substrate insertion groove 36 and the end portion of the projection 34 is also inclined, when the glass substrate is inserted into the buffer member 30, The glass substrate can be inserted smoothly without hitting the buffer. In addition, the projection 34 preferably serves as a guide of the glass substrate when the glass substrate is inserted and removed, and serves to support the inserted glass substrate, so that the cross-sectional shape is preferably rectangular or trapezoidal.

In addition, since the protrusions 34 and the glass substrate insertion grooves 36 are formed on only one surface of the buffer material 30, heat deformation may occur during the manufacture of the buffer material 30, and thus the protrusions 34 and the glass substrate insertion grooves may be formed. It is preferable to form a plurality of fastener inserting grooves 39 on the back surface on which 36 is formed, and to form a plurality of thin grooves 38 between the fastener inserting grooves 39 to prevent deformation.

When the glass substrate 100 is transported, it is transported in a carrying box 200, wherein the fixing insert groove is fixed when the packing buffer material 30 is fixed to the carrying box 200 with a fixture (angle, etc.) (not shown). (39) will be used.

8 is a view showing a second embodiment according to the present invention, the horizontal buffer member 42 and the horizontal buffer member 42 in which the projections 44 and the glass substrate insertion grooves 46 are alternately formed on the upper surface at regular intervals. 42 is vertically erected in one end of the L-shape, and the projections 44 'are formed in the same manner as the projections 44 and the glass substrate insertion grooves 46 formed in the horizontal buffer 42. The cushioning material for packaging is formed by the vertical buffer member 40 in which the glass substrate insertion groove 46 'is alternately formed, and one end of the projections 44 and 44' formed in the horizontal buffer member 42 and the vertical buffer member 40 is formed. The shape of the one part is inclined so that it may become low toward an outer side.

In addition, the cross-sectional shape of the projections 44 and 44 'is preferably rectangular or trapezoidal, and may vary the vertical length of the vertical buffer 40 and the horizontal length of the horizontal buffer 42.

When transporting or storing the glass substrates, if the edges of the glass substrates are inserted into the glass substrate insertion grooves 46 and 46 'formed in the horizontal and vertical buffers, the glass substrates are not in contact with each other by the projections 44 and 44'. The compartments are packaged and the glass substrate is safe even from vibrations and external shocks.

In addition, since the vertical buffer 40 and the horizontal buffer 42 have protrusions 44 and 44 'and glass substrate insertion grooves 46 and 46' formed on only one surface thereof, heat deformation may occur when the cushioning material is processed. It may be possible to prevent deformation by forming a plurality of thin grooves on the back surface of the insertion groove is formed.

The protrusions 54 and the glass substrate inserting grooves 56 are formed integrally with each other at regular intervals, and the protrusions 57 for connecting the shock absorbing material are spaced apart from the buffer 50 or 51 at regular intervals. It is a cushioning material for packaging of glass substrates molded in one piece with the connecting portion 53.

The cushioning material for packaging of the third embodiment is used to be fixed to the bottom of the glass substrate transport box 200, and when fixed, a fixture (angle, etc.) (not shown) is provided in the gap between the buffer material connection part 53 and the buffer material connection part 53. To fix it. In addition, when two or more packaging buffers are used in connection, or when the packaging buffers of the same type as in the first embodiment of the present invention are used in connection, it is used to connect to the substrate connecting protrusion 57.
