Patent Document 1 discloses a wrapper in which a laminate in which a glass plate and a laminate are alternately stacked horizontally is wrapped in a wrapping pallet. In addition, Patent Document 1 discloses that a laminate is loaded on a buffer member (resin sheet) of a wrapping pallet and wrapped.

The glass plate of the laminate is a mother glass substrate for a flat panel display (FPD) such as a liquid crystal display or a plasma display, or a glass plate of an intermediate product in the manufacturing process thereof.

4 (a) to 4 (d) and 5 (a) to 5 (c) show the glass plate G of the laminate 3 loaded on the buffer member 2 of the packing pallet 1, , And a procedure for extracting the laminate 4 of the laminate 3 from the laminate 3 one by one.

Fig. 4 (a) is a view showing that the paper pressing jigs 5, 5 are disposed apart from the side of the layered product 3. 4 (b), the paper pressing jigs 5, 5 are moved toward the side surface of the multilayer body 3 by the driving means (not shown), and are moved downward from the rim of the glass plate G The end of the bent piece 4 is pressed by the paper pressing jigs 5, 5. Thereby, the laminated body 3 except the uppermost glass plate G is held by the paper pressing jigs 5, 5.

Subsequently, as shown in Fig. 4C, the uppermost glass sheet G is held by suction by the adsorption pads 6, 6, ..., and extracted from the laminate 3. At this time, the air is blown between the uppermost glass sheet G and the uppermost sheet 4 as shown by arrow A, and the uppermost glass sheet G is conveyed upward by the adsorption pads 6, 6, .

4 (d), the paper pressing jigs 5, 5 are retracted to the side of the layered product 3 in order to extract the uppermost laminated paper 4 from the laminated body 3. Next, as shown in Fig.

5 (a) and 5 (b), the uppermost laminate 4 is held by suction by the adsorption pads 7, 7 ..., and extracted from the laminate 3. At this time, as shown by the arrow B, air is blown between the uppermost laminate 4 and the uppermost glass plate G, and the uppermost laminate 4 is pressed against the adsorption pads 7, 7 ... Thereby lifting it upward.

By the above operation, the glass plate G and the laminated paper 4 are extracted one by one from the stacked body 3 as shown in Fig. 5 (c). Thereafter, the operations of Figs. 4 (b) to 5 (b) are repeated to extract both the glass plate G and the laminate 4 from the cushioning member 2.

International Publication No. 2008/105190

In the conventional garniture, during the operation of pressing the adsorption pad 7 onto the upper surface of the lumber 4, or during the operation of lifting the lumber 4 upward by the adsorption pad 7, There is a problem that the laminated sheet 4 slides sideways with respect to the cushioning member 2. This problem does not occur because the weight of the layered product 3 is heavy at the beginning of the extraction process of the glass plate G. However, in the ending stage where the glass plate G is shortly left, If the amount of slip to the side of the laminate 4 is large, the relative positions of the adsorption pad 6 and the glass plate G are largely shifted to cause poor adsorption, so slip to the side of the laminate 4 must be avoided.

Further, in the conventional warp bodies, there is a case where the last laminate 4 is closely attached to the cushioning member 2 by the weight of the layered product 3. [ Therefore, when the adhesion between the last laminate 4 and the buffer member 2 is larger than the force for lifting the last laminate 4 by the adsorption pad 7, the last laminate 4 is held between the buffer member 2 It can not be extracted smoothly. That is, the last lobe 4 is separated from the adsorption pad 7 or the last lobe 4 is torn.

According to one aspect of the present invention, when the coefficient of static friction between the sheet and the cushioning member is less than 0.2, the coefficient of static friction is so small that when the sheet is taken out from the cushioning member, As well as the fact that the When the coefficient of static friction exceeds 0.8, the coefficient of static friction is too large. Therefore, when the last sheet of the laminate is taken out of the cushioning member, the last sheet is separated from the adsorption pad or the last sheet is torn.

Therefore, by defining the coefficient of static friction between the sheet and the buffer member to 0.2 to 0.8, it is possible to prevent the last sheet from slipping sideways relative to the buffer member when the sheet is extracted from the laminate, So that it is possible to smoothly extract it from the buffer member.

According to one aspect of the present invention, it was experimentally confirmed that even when the coefficient of static friction is 0.3, the last sheet does not slip sideways relative to the buffer member when the sheet is taken out from the laminate.

In one aspect of the present invention, when the mass of the plate is less than 6.5 kg, the coefficient of static friction is preferably 0.5 or more.

The plate thickness of the plate body is 0.7 mm, and the glass plate of the sixth generation (1500 mm in length × 1800 mm in length to 1500 mm in width × 1850 mm in width) has a mass of about 4.8 kg. According to one aspect of the present invention, it was experimentally confirmed that even when the coefficient of static friction was 0.5 in the glass plate of the above-mentioned size, the last sheet did not slip sideways relative to the buffer member when the sheet was taken out from the laminate.

In one embodiment of the present invention, it is preferable that the sheet is a laminate having a roughness of 18 seconds or less (JIS P 8119, 1976).

In the laminate 14 of the embodiment, the laminate 12 is exemplified as a sheet interposed between the glass sheet G and the glass sheet G, but the present invention is not limited to the laminate 12. For example, a sheet such as a resin film and a foam buffer can be used instead of the lumber 12.

When the laminate 12 is used as the sheet, the raw material of the laminate 12 is preferably virgin pulp, but a raw material containing cellulose or the like may be used. Further, the lumber 12 has a smooth surface of 18 seconds or less (JIS P 8119, 1976) and has a reduced contact area so that the resin component of the lumber 12 is transferred to the glass plate G, The lipid that does not occur is selected and used. In addition, the resin content of the lumber 12 is 0.05 mass% or less (JIS P 8205, 1976), and a lipid which does not adversely affect the quality of the glass plate G itself is selected and used by the combined effect with the above-

<Packing pallet (16)>

As shown in Fig. 2, the packing pallet 16 mainly consists of a rectangular base 20, a plate-shaped buffer member 22 and a lint-piece pressing member 24 in a plan view. Since the columnar guide members 26, 26, ... constituting the pallet stacking member are installed upright on the four corners of the packing pallet 16, a plurality of the packing pallets 16 are stacked in the vertical direction, . &Lt; / RTI &gt;

The pedestal 20 is made of aluminum or aluminum alloy in terms of weight, rigidity and cost. 1 and 2, two openings 28 for forklifts into which a fork of a forklift (not shown) is inserted are formed on two sides of one side of the pedestal 20, . Thereby, the fork of the forklift can be inserted from all directions of the longitudinal and transverse sides of the pedestal 20 with respect to the packing pallet 16.

A cushioning member 22 having a rectangular shape is disposed on the upper surface of the pedestal 20 with a support plate 30 interposed therebetween. The stacked body 14 is stacked on the upper surface of the buffer member 22 via the joint paper 12 located at the lowermost part. The cushioning member 22 may be a member having cushioning property made of foamed polyurethane or foamed polypropylene or the like, and is not particularly limited.

As shown in Fig. 1, the joint pressing members 24 are arranged on the respective sides of four sides of the receiving tray 30 at predetermined intervals, for example two at a time, and are fixed to the receiving tray 30 by screws 32, Is fixed. When the joint pressing member 24 is fastened by the screw 32, the glass plate G is pressed from the side surface by the joint pressing member 24, and the joint pressing members 24, And is supported by mutual interlocking. In addition, the laminated paper pressing member 24 presses the laminated paper 12 out of the four sides of the glass plate G toward the end face of the glass plate G. This completes the construction of the garment body 10.

[Features of Gonpoche (10)]

The goniometer body 10 is characterized in that the coefficient of static friction between the laminate 12 measured in accordance with JIS K 7125: 1999 or ISO 8295: 1995 and the buffer member 22 is 0.2 to 0.8.

3 is a perspective view showing a measurement apparatus 40 for measuring the static friction coefficient according to JIS K 7125: 1999.

3, a sample piece 44 obtained by cutting the cushioning member 22 to a predetermined size is placed on the upper surface of the sample piece 42 obtained by cutting the laminated paper 12 into a predetermined size. And a load member 46 of 200 g (1.96 N) is placed on the upper surface of the sample piece 44. The sample piece 44 is pulled in the horizontal direction as shown by the arrow C by the pulling member 48, The load cell 50 measures the force generated at the time of the measurement.

The force is increased linearly to reach the maximum load. This maximum load is the static friction force Fs, and the static friction coefficient is calculated by multiplying the static friction force Fs by Fp (normal force generated by the mass of the load body 46: 1.96 N) (Fs / Fp). The above is the outline of the measuring apparatus 40.

The present inventors have focused on the coefficient of static friction between the last laminate 12 of the layered product 14 and the buffer member 22 of the packing pallet 16 as a means for solving the problem of conventional gonoceles. A suitable coefficient of static friction for preventing the last joint 12 from slipping sideways relative to the cushioning member 22 and a suitable coefficient of static friction for smoothly extracting the last joint 12 from the cushioning member 22, And was derived from an experiment using an actual device (goniometer 10) and the measuring device 40 of Fig.

That is, when the static friction coefficient is 0.2 or more, the static friction coefficient is not too small. Therefore, when extracting the laminate 12 from the laminate body 14, the last laminate 12 does not slide sideways with respect to the cushioning member 22 As an experiment. When the trailing edge 12 of the laminate body 14 is extracted from the cushioning member 22, the distance between the last edge 12 and the suction pad 22 7) (see FIG. 5) fell, or the last laminate 12 did not tear.

Therefore, by defining the coefficient of static friction between the laminate 12 and the buffer member 22 to be 0.2 to 0.8, when the laminate 12 is extracted from the laminate 14, the last laminate 12 is pressed against the buffer member 22, And it is also possible to smoothly extract the last laminate 12 of the laminate 14 from the cushioning member 22. Therefore, the conventional problem can be solved.

It has been experimentally confirmed that the last laminate 12 does not slip sideways with respect to the buffer member 22 when the laminate 12 is extracted from the laminate 14 even if the coefficient of static friction is 0.3 in the seventh generation glass plate G .

Also, in the case where three or more glass plates G of the seventh generation having a plate thickness of 0.3 mm were stacked on the last lamination 12, the total mass of three or more glass plates G was equal to or more than 6.5 kg and less than 9 kg.

In the third embodiment, when the mass of the glass plate G is less than 6.5 kg, it is preferable to set the coefficient of static friction to 0.5 or more.

The plate thickness is 0.7 mm, and the sixth generation glass plate G has a mass of about 4.8 kg. It is experimentally confirmed that the last laminate 12 does not slide sideways with respect to the buffer member 22 when the laminate 12 is extracted from the laminate 14 even if the coefficient of static friction is 0.5 in the glass plate G of the sixth generation Respectively.

Also in the case where three or more glass plates G of the sixth generation having a plate thickness of 0.3 mm were stacked on the last lamination 12 and the total mass of three or more glass plates G was less than 6.5 kg.
