Description

Glass plate packing pallet and glass plate package

The present invention relates to a glass plate packing pallet and a glass plate package.

In recent years, along with the increase in size and thickness of glass substrates for flat panel displays, the packaging of glass substrates is mainly performed in a state where the glass substrates are stacked in a vertical posture. Moreover, as a pallet for packing in a state in which glass substrates are stacked in a vertical posture, a base support portion for supporting the bottom side of a glass substrate laminate formed by laminating a plurality of glass substrates in a vertical posture, and a glass substrate laminate What is provided with the back surface support part which supports the back surface of this is common. In this case, the glass substrate laminate is placed on the pallet (on the support surface at the bottom) and fixed to the pallet by an appropriate means.

By the way, when transporting a package using this kind of pallet, the displacement of the glass substrate laminate due to vibration during transport becomes a problem. Since the end face of the glass substrate may cause unnecessary contact with the surroundings due to deviation from the packaging position, this kind of deviation must be prevented as much as possible.

Here, for example, Patent Document 1 discloses a structure for sandwiching both ends in the width direction of a glass substrate laminate in a state of being placed on a pallet. That is, this structure has a pair of plate materials that can come into contact with both end surfaces in the width direction of the glass substrate laminate, and allows the pair of plate materials to be close to or separated from both end surfaces in the width direction of the glass substrate laminate by a screw mechanism. Is.

JP 2005-154010 A

According to the structure described in Patent Document 1, since the glass substrate laminate in a state of being placed on the pallet can be sandwiched and fixed from both sides in the width direction, the effect of preventing the shift of the glass substrate laminate in the width direction during transportation can be prevented. I can expect. However, in the structure as described in Patent Document 1, since a mechanism for holding the glass substrate laminate is large, there is a concern that the pallet structure is complicated and the pallet is enlarged. In this case, the production cost of the pallet is increased, and the increase in the transportation cost accompanying the decrease in the transportation efficiency may be a problem.

The above problems are not limited to the case of sandwiching both ends in the width direction of the glass substrate laminate, and may occur in the same manner when a member that presses the front surface of the glass substrate laminate, such as a press bar, is used.

In view of the above circumstances, in this specification, it is a technical problem to be solved by the present invention to provide a pallet that can be packed in a state in which a glass plate laminate is easily pressed.

The solution of the technical problem is achieved by the glass plate packing pallet according to the present invention. That is, this pallet includes a bottom support portion that supports the bottom of a glass plate laminate formed by laminating a plurality of glass plates in a vertical posture, a back support portion that supports the back surface of the glass plate laminate, a back support portion, and A glass plate packaging pallet comprising a belt for binding a glass plate laminate, and a press member disposed between the belt and the glass plate laminate, wherein the press member is in surface contact with the belt. It is characterized by the point provided with the protrusion part which protrudes from the contact surface of this, and controls the movement to the short side direction of a belt.

As described above, in the pallet according to the present invention, the pressing member protrudes from the contact surface in surface contact with the belt and is provided with a protruding portion that restricts the movement of the belt in the short direction. According to this configuration, even if the belt is displaced in the lateral direction, it is possible to prevent the belt from being detached from the pressing member by contacting the protruding portion. In addition, as described above, when the belt is disposed so as to bind the glass plate laminate and the back support unit laminated in the vertical posture, the pressing member brings the short side direction of the contact surface closer to the vertical direction. In this state, it is disposed between the belt and the glass plate laminate. Therefore, by arranging the pressing bar so that the protruding portion protruding from the contact surface is positioned on the upper side in the height direction of the contact surface, for example, the protruding portion is supported by the belt. Thereby, even if it does not fix to the other element which comprises a pallet, the subsequent packing operation | work can be implemented in the state from which the operator released the hand from the pressing member, for example. Therefore, the packing operation can be performed very easily. In addition, since the pressing member can be made very simple, it is possible to avoid the situation where the structure of the pallet becomes complicated and large, and to keep the production cost of the pallet and the transportation cost of the package low. Become.

Further, the glass plate packing pallet according to the present invention may be one in which the protruding portion has a wall shape and is provided in pairs on both sides in the short direction of the contact surface. In this case, the protrusion height from the contact surface of the pair of protrusions may be set larger than the thickness dimension of the belt.

In this way, the projecting portion has a wall shape, and a pair of both sides in the short direction of the contact surface is provided, so that even if the belt is displaced to either side in the short direction, of the pair of projecting portions A situation in which the belt is detached from the pressing member can be effectively prevented by always contacting either one of the protrusions. Further, in this case, by setting the protrusion height of the pair of protrusions as described above, it is possible to avoid the situation where the belt gets over the protrusion due to an unexpected impact or the like with high probability.

In the glass plate packing pallet according to the present invention, the pressing member may be a side stopper that presses the glass plate laminate from both sides in the width direction.

Further, when the pressing member is a side stopper, the glass plate packing pallet according to the present invention may have a pair of protruding portions provided over the entire length of the contact surface.

By doing so, since the belt and either one of the protrusions are in contact with each other over a wide range, it is possible to more effectively prevent the belt from coming off the side stopper.

Further, when the pressing member is a side stopper, the glass plate packing pallet according to the present invention is provided with a top portion across the pair of projecting portions, and in a region surrounded by the top portion and the pair of projecting portions. A through hole into which the belt can be inserted may be formed.

By providing a through hole in the side stopper in this way, it is possible not only to shift the belt in the short direction but also to restrict the movement of the belt in the normal direction. Therefore, it is possible to more reliably prevent the belt from coming off the side stopper.

Further, in the glass plate packing pallet according to the present invention, the pressing member may be a pressing bar that presses the glass plate laminated body from the front side.

In addition, when the pressing member is a pressing bar, the glass plate packing pallet according to the present invention has two pressing bars, each of which has a pair of protruding portions, and each pair of protruding portions has one end in the longitudinal direction of the contact surface and the other. It may be formed at the end.

Since the pressing bar is for pressing the front side of the glass plate laminate, the size in the longitudinal direction is usually the size according to the size in the width direction of the glass plate. Therefore, for example, when a pair of protrusions are provided in the entire longitudinal direction of the contact surface, the weight of the pressing bar itself may reach a size that cannot be ignored compared to the weight of the entire pallet. Therefore, as described above, the two pairs of protrusions are provided only at one end and the other end in the longitudinal direction of the presser bar, respectively, while effectively preventing the belt from shifting in the short direction, the presser bar itself It is possible to keep the weight of the material within an appropriate range.

Further, when the pressing member is a pressing bar, the glass plate packing pallet according to the present invention may be configured such that the lifting restricting portion that restricts the lifting of the belt is provided across the pair of protruding portions. Good.

Thus, by providing the lifting restricting portion, it is possible not only to shift the belt in the short direction but also to restrict the movement of the belt in the normal direction. Therefore, it is possible to more reliably prevent the belt from coming off the press bar.

Further, in the case where the lifting restricting portion is provided in the pair of projecting portions, the glass plate packing pallet according to the present invention may have a portion in which the lifting restricting portion forms a columnar shape.

By making the lifting restricting portion have the above-described shape, the contact between the belt and the lifting restricting portion is reduced. Further, since the belt can be easily inserted between the lifting restriction portion and the contact surface, the pressing bar can be easily attached to the belt.

Further, in the case where the lifting restricting portion is provided in the pair of projecting portions, the glass plate packaging pallet according to the present invention is such that the lifting restricting portion is rotatably supported with respect to the pair of projecting portions. There may be.

By supporting the lifting restricting portion in a rotatable manner, it becomes easier to insert the belt between the lifting restricting portion and the contact surface. Further, since friction with the belt can be reduced, it is possible to suppress wear of the belt at the time of attachment.

The glass plate packing pallet according to the above description can easily perform the packing operation of the glass plate laminate while effectively preventing the belt from being detached from the pressing member. It becomes possible to provide suitably as a glass plate packing body provided with the pallet for glass and the glass plate laminated body mounted in the pallet for glass plate packing.

As described above, according to the pallet for packing a glass plate according to the present invention, it is possible to easily pack the glass plate laminated body in a pressed state.

<First embodiment of the present invention>
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. In the present embodiment, a case where a glass plate to be packaged is a glass substrate for flat panel display, and a glass substrate package in a state in which the glass substrate is laminated via interleaf is described as an example.

FIG. 1 is a perspective view of a glass plate package 1 according to the first embodiment of the present invention. The glass plate package 1 includes a glass plate packing pallet 2 and a glass plate laminate 3 packed on the glass plate packing pallet 2.

The glass plate laminate 3 is formed by laminating a plurality of rectangular or square glass plates G in a vertical posture through interleaf paper I. In the present embodiment, the interleaf paper I is disposed on the backmost side of the glass plate laminate 3.

Here, an example of the specifications regarding the glass plate laminate 3 will be described. The weight of the glass plate laminate 3 is 200 kg to 3800 kg. At this time, the number of glass plates G constituting the glass plate laminate 3 is 200 to 400, the size of the glass plate G is 1000 mm × 1200 mm to 2500 mm × 2500 mm, and the thickness of the glass plate G is 300 μm to 700 μm. It is. The interleaf paper I used for the glass plate laminate 3 is, for example, pure pulp paper. The size of the interleaf paper I is usually larger than that of the glass plates G and is alternately arranged with the glass plates G so that the glass plates G do not directly contact each other. Thereby, the glass plate laminated body 3 by which the glass plate G and the slip sheet I are laminated | stacked alternately is comprised.

The pallet 2 for packing glass plates mainly includes a base part 4, a back support part 5, a bottom support part 6, a holding part 7, a buffer plate 8, and a base plate 9 on the bottom side. The back support part 5 stands up from the base part 4 and supports the back face of the glass plate laminate 3. The bottom support 6 supports the bottom (lower end) of the glass plate laminate 3 on the base 4. The buffer plate 8 is disposed between the glass plate laminate 3 and the back support 5, and the bottom side receiving plate 9 is disposed between the glass plate laminate 3 and the bottom support 6. In the present embodiment, as shown in FIG. 2, three buffer plates 8 are arranged on the front surface 5 a side of the back surface support portion 5, and one bottom side receiving plate 9 is an upper surface 6 a of the bottom surface support portion 6. It is arranged on the side.

Moreover, in this embodiment, as shown in FIG. 2, the sum total of the width direction dimension (here, the width direction here is the same as the width direction of the glass plate G. The following is the same) of the buffer plate 8 is the back surface. The buffer plate 8 is attached to a region smaller than the width direction dimension of the front surface 5a of the support portion 5 and excluding the upper edge portion and both side edge portions of the front surface 5a. Under the present circumstances, the area of the glass plate G of the glass plate laminated body 3 is smaller than the area of the front surface 8a of the buffer plate 8, and in the state which laminated | stacked the glass plate G as shown in FIG. It is in a state of protruding from the plate G (glass plate laminate 3). Accordingly, the entire surface of the glass plate G is supported by the front surface 8a of the buffer plate 8 (via the interleaf paper I).

Further, as shown in FIG. 3, the front surface 5a of the back support portion 5 is inclined backward by a predetermined angle (for example, 5 ° to 25 °) with respect to the vertical direction. Further, the front surface 5a of the back surface support portion 5 is at an angle of, for example, 90 ° to 100 ° with respect to the upper surface 6a of the bottom side support portion 6 (that is, the support surface 9a of the receiving plate 9 on the bottom side). The upper surface 6a of 6 (the support surface 9a of the receiving plate 9 on the bottom side) is inclined with respect to the horizontal direction of 10 ° to 25 °, for example.

The buffer plate 8 and the base plate 9 on the bottom side can be formed of a material having a relatively high elasticity (low rigidity) such as a foamed resin. As one specific example, both the buffer plate 8 and the base plate 9 are made of foamed polypropylene as a main material.

In this embodiment, as shown in FIG. 1, the holding unit 7 includes a belt 13, a pressing bar 14 as a pressing member, and a side stopper 15 as main elements. The belt 13 includes a ratchet portion 16 (a so-called ratchet belt), for example, and is hung on a hook 17 disposed behind the back support portion 5 so as to be doubled. It is fixed in a state of being tightened by the ratchet portion 16 or the like on the contact surface 14a in surface contact with the belt 13 on the surface opposite to the glass plate laminate 3. At this time, as shown in FIGS. 1 and 4, the front side receiving plate 18 is placed on the foremost side of the glass plate laminate 3, and further on the front side of the front side receiving plate 18. A frame plate 19 is placed. The frame plate 19 is provided with a hook 20. With the presser bar 14 placed on the hook 20, the presser bar 14 is attached to the belt 13 together with the glass plate laminate 3, the front receiving plate 18 and the frame plate 19. Therefore, it can be pressed to the back support portion 5 side.

Among these, as shown in FIG. 5, the presser bar 14 is attached to the belt 13 with its longitudinal direction aligned with the width direction of the glass plate laminate 3 (disposed on the front side of the glass plate laminate 3). ) In the present embodiment, the two pressing bars 14 are arranged along the width direction of the glass plate laminate 3.

Further, as shown in FIG. 6, a pair of projecting

portions

21a and 21b projecting from the contact surface 14a are provided on both sides of the contact surface 14a in surface contact with the belt 13 in the longitudinal direction of the pressing bar 14. It has been. In the present embodiment, the pair of projecting

portions

21a and 21b are both wall-shaped and extend along the longitudinal direction of the contact surface 14a (pressing bar 14). The pair of

protrusions

21a and 21b are opposed to each other in the short direction of the contact surface 14a and are disposed in the vicinity of both ends of the contact surface 14a in the longitudinal direction. In this case, the facing interval w1 between the pair of

protrusions

21a and 21b is set to be not less than the width direction dimension w2 of the belt 13 as shown in FIG. As a result, the belt 13 can be brought into surface contact with the contact surface 14a over the longitudinal direction in a state of being disposed between the pair of projecting

portions

21a and 21b.

In the present embodiment, the protrusion height t2 (see FIG. 6) of the pair of

protrusions

21a and 21b from the contact surface 14a is set to be larger than the thickness t1 of the belt 13 (see FIG. 6). Yes. Thereby, it is possible to prevent as much as possible the situation where the belt 13 gets over the one protruding portion 21a (or protruding portion 21b).

The side stopper 15 is disposed between the glass plate laminate 3 and the belt 13 on both sides in the width direction of the glass plate laminate 3 as shown in FIG. Further, a pair of projecting

portions

22a and 22b projecting from the contact surface 15a are provided on both sides in the lateral direction of the contact surface 15a (see FIG. 5) of the side stopper 15 that is in surface contact with the belt 13 in the longitudinal direction. ing. In the present embodiment, the pair of

protrusions

22a and 22b are both wall-shaped and extend along the longitudinal direction of the contact surface 15a (side stopper 15). The pair of projecting

portions

22 a and 22 b are disposed to face each other over the entire longitudinal direction of the contact surface 15 a, that is, the entire longitudinal direction of the side stopper 15. In this case, although not shown, the facing distance between the pair of

protrusions

22 a and 22 b is set to be equal to or larger than the width direction dimension of the belt 13. As a result, the belt 13 can come into surface contact with the contact surface 15a in the longitudinal direction in a state of being disposed between the pair of

protrusions

22a and 22b (see FIGS. 1 and 5).

Thus, in the pallet 2 according to the present invention, the protruding portion 21a (or the protruding portion 21b) that protrudes from the contact surface 14a that is in surface contact with the belt 13 in the pressing bar 14 and restricts the movement of the belt 13 in the short direction. It was made to provide. According to this configuration, even if the belt 13 is displaced in the short direction, it is possible to prevent the belt 13 from being detached from the pressing member by contacting the protruding portion 21a (or the protruding portion 21b). In particular, as in the present embodiment, the

protrusions

21a and 21b are formed in a wall shape and are provided in pairs on both sides in the short direction of the contact surface 14a, so that the belt 13 can be on either side in the short direction. Even if they deviate, the belt 13 can be effectively prevented from coming off the holding bar 14 by always contacting one of the pair of

protrusions

21a and 21b.

Further, in the present invention, of the side stopper 15 as a pressing member, the belt 13 protrudes from the contact surface 15a on both sides of the contact surface 15a in surface contact with the belt 13 and restricts the movement of the belt 13 in the short direction. Since the pair of projecting

portions

22a and 22b are provided, it is possible to effectively prevent the belt 13 from being detached from the side stopper 15. Further, since the protruding portion 22b located on the upper side in the vertical direction among the pair of protruding

portions

22a and 22b protruding from the contact surface 15a is supported by the belt 13, the operator releases his / her hand from the side stopper 15. The subsequent packing operation can be performed in the state, and the packing operation can be simplified. Furthermore, since the side stopper 15 can have a very simple structure, a situation in which the structure of the pallet 2 is complicated and enlarged can be avoided, and the production cost of the pallet 2 and the transportation cost of the package 1 can be reduced. It becomes possible to suppress.

As mentioned above, although 1st embodiment of the pallet for glass plate packing which concerns on this invention, and a glass plate package is described, naturally this pallet and package can take arbitrary forms within the scope of the present invention.

<Second embodiment of the present invention>
For example, with respect to the presser bar 14, in the first embodiment, a pair of

protrusions

21a and 21b for restricting movement of the belt 13 in the width direction is illustrated only in the vicinity of both ends in the longitudinal direction of the contact surface 14a. However, it is of course possible to take other forms. FIG. 8 shows a perspective view of the holding bar 14 according to the second embodiment of the present invention. As shown in this figure, the pair of projecting

portions

23a, 23b according to the present embodiment is disposed over the entire length of the contact surface 14a, that is, the entire length of the presser bar 14 in this case. By doing in this way, since the belt 13 and either one of the

protrusions

23a and 23b are in contact with each other over a wide range, it is possible to more effectively prevent the belt 13 from coming off the holding bar 14. It becomes.

Of course, the arrangement of the pair of protrusions 21 is arbitrary as long as the belt 13 can be disposed between them. For example, the pair of

protrusions

21a and 21b in the form shown in FIG. 6 are intermittently connected in the longitudinal direction of the contact surface 14a. It is also possible to provide them separately (provided at places other than both ends such as the center in the longitudinal direction).

Moreover, although the case where the pair of protruding

portions

21a and 21b are opposed to each other in the short direction of the contact surface 14a has been illustrated in the above illustrated example (see FIG. 7 and the like), it is of course not limited to this form. For example, although illustration is omitted, it is also possible to arrange the one projecting portion 21a and the other projecting portion 21b to be partially overlapped in the longitudinal direction or alternately arranged so as not to overlap at all.

<Third embodiment of the present invention>
Further, the pressing bar 14 is provided not only with a member (a pair of

protrusions

21a and 21b) for restricting movement of the belt 13 in the width direction (short direction of the contact surface 14a), but also with the belt 13 method. It is also possible to provide a member for restricting movement in the linear direction (lifting from the contact surface 14a). FIG. 9 shows a perspective view of the holding bar 14 according to the third embodiment of the present invention. As shown in this figure, the holding bar 14 according to the present embodiment has a pair of projecting

portions

24a and 24b facing each other in the short direction of the contact surface 14a, and is disposed across the pair of projecting

portions

24a and 24b. It further has a floating restricting portion 25. By configuring the pressing bar 14 in this way, the belt 13 is restricted from moving in the short direction of the contact surface 14a by the pair of

protrusions

24a and 24b, and is also moved in the normal direction (lifted). It is regulated by the regulation unit 25. Therefore, it is possible to more reliably prevent the belt 13 from being detached from the holding bar 14 due to an unexpected impact or the like.

Further, as shown in FIG. 9, the lifting restricting portion 25 may have a cylindrical shape at least a portion that may come into contact with the belt 13. By doing so, the contact between the belt 13 and the lifting restricting portion 25 is reduced. In addition, since the belt 13 can be easily inserted between the lifting restricting portion 25 and the contact surface 14a, the pressing bar can be easily attached to the belt 13.

Further, in this case, the lifting restricting portion 25 may be supported rotatably with respect to the pair of projecting

portions

24a and 24b. In this way, the lifting restricting portion 25 functions as a roller, so that it becomes easier to insert the belt 13 between the lifting restricting portion 25 and the contact surface 14a. In addition, since friction with the belt 13 can be reduced, wear of the belt 13 at the time of attachment can be suppressed.

<Fourth embodiment of the present invention>
Further, the side stopper 15 can take a form other than that shown in FIG. FIG. 10 is a front view of the side stopper 26 according to an example (fourth embodiment of the present invention). As shown in this figure, the side stopper 26 according to the present embodiment further has a top portion straddling a pair of projecting portions projecting from both sides of the contact surface with the belt 13 in the short direction (vertical direction in FIG. 10). And a through hole 27 through which the belt 13 can be inserted is provided in a region surrounded by the top, the pair of protrusions, and the contact surface. By providing the through hole 27 in the side stopper 26 as described above, the belt 13 is surrounded on all sides at least in a contact area with the side stopper 26. Therefore, the belt 13 can be regulated not only in the lateral direction but also in the normal direction of the belt 13, and the belt 13 can be more reliably prevented from coming off the side stopper 26. Become.

In the above embodiment, for example, as shown in FIGS. 1 and 5, the pair of

protrusions

22 a and 22 b are disposed over the entire longitudinal direction of the contact surface 15 a, that is, over the entire longitudinal direction of the side stopper 15. Although illustrated, of course, other forms are possible. For example, although not shown in the figure, the pair of protruding

portions

22a and 22b may be disposed only at both ends of the side stopper 15 in the longitudinal direction.

In the above description, when the pressing bar 14 and the side stopper 15 are both provided as the pressing member, and the pair of

protrusions

21a and 21b (22a and 22b) according to the present invention are provided for both the pressing bar 14 and the side stopper 15. (See FIG. 1 and the like), but of course not limited to this. For example, it is possible to adopt a configuration in which only one of the pressing bar 14 and the side stopper 15 is provided with a pair of protruding portions, and in that case, a configuration in which the pressing member on the side where the pair of protruding portions is not provided is omitted. It is also possible to take. In short, as long as there is at least one pressing member capable of pressing the glass plate laminate 3 by the belt 13 and a pair of protrusions are provided on the pressing member, the glass plate packing pallet 2 according to the present invention. Can take any form.

<Fifth embodiment of the present invention>
Hereinafter, a fifth embodiment of the present invention will be described with reference to FIGS. 11 and 12.

FIG. 11 is a side view of the glass plate package 1 according to the fifth embodiment of the present invention, and FIG. 12 is a view of the glass plate package 1 viewed from the direction of arrow E in FIG. As shown in FIGS. 11 and 12, the glass plate packing body 1 and the glass plate packing pallet 2 according to the present embodiment include a holding bar 14 provided with a pair of

protrusions

21a and 21b (22a and 22b), respectively. A pair of restricting members 28 for restricting movement of the glass plate laminate 3 in the width direction are provided on both sides of the lower end of the glass plate laminate 3 in a state of being provided with a side stopper 15 and stacked in a vertical posture. And a support portion 29 that supports the device. The support part 29 is arrange | positioned on the base part 4, as shown, for example in FIG.

In the present embodiment, a buffer member 30 is disposed between the regulating member 28 and the glass plate laminate 3, and the glass plate laminate 3 is sandwiched between the pair of regulating members 28 via the cushion member 30. It has become.

Thus, by providing the pair of regulating members 28, it is possible to more reliably fix the glass plate laminate 3 and reliably prevent displacement during transportation. In addition, since only the pair of regulating

members

28 and 28 and the support portion 29 that supports this, in other words, a structure for fixing the lower end of the glass plate laminate 3 without having an operating portion can be obtained. A simple structure can be used, and the production cost can be avoided. Moreover, since it is a very simple structure, compared with the mechanism clamped like patent document 1, the enlargement of the pallet 2 for glass plate packing, especially the enlargement of the width direction can be avoided. As a result, it is possible to reduce the transportation efficiency and the transportation cost.

<Sixth embodiment of the present invention>
In addition, when the pair of regulating

members

28 and 28 are plate-shaped as shown in FIG. 11, the regulating member 28 may be configured to be detachable from the support portion 29. FIG. 13 is a side view of the glass plate package 1 according to the sixth embodiment of the present invention. In this case, for example, as shown in FIG. 13, a slit 29 a for inserting the regulating member 28 is provided in the support portion 29 (opening is formed on the upper surface of the support portion 29), and the glass plate laminate 3 or the like is first formed. Is placed. Thereafter, after the regulating member 28 is inserted into the slit 29 a and the regulating member 28 is attached to the support portion 29, the buffer member 30 is disposed between the regulating member 28 and the glass plate laminate 3. If it does in this way, it will become possible to perform the lamination operation | work of the glass plate G, and subsequent packing operation | work easily and efficiently.

The buffer member 30 is desirably formed of a material having relatively low rigidity and high elasticity, like the

buffer plates

8 and 9. If the material is made of a material having elasticity (so-called elastic body), the impact of the shock absorbing member 30 can be absorbed when the impact is received when the glass plate package 1 is transported. Can be prevented as much as possible. Examples of the material rich in elasticity include elastomers such as rubber and foamed resins. However, foamed resins can contribute to a reduction in weight. In particular, a polyolefin-based foamed resin is expected to exhibit elasticity suitable for this kind of shock absorption. Moreover, although the bubble in a foamed resin may be an open cell or a closed cell, the closed cell is preferable from a viewpoint of impact absorption.

<Seventh embodiment of the present invention>
Further, the buffer member 30 may be composed of only one material, or may be composed of two or more materials. FIG. 14: has shown the principal part enlarged view of the glass plate package 1 which concerns on the example (7th embodiment of this invention). As shown in this figure, the buffer member 30 according to the present embodiment is configured by combining a first buffer layer 30a and a second buffer layer 30b, which are made of different materials. Here, for example, the first buffer layer 30a on the side close to the lower end of the glass plate laminate 3 may be formed of a material that is harder (higher elastic modulus) than the second buffer layer 30b on the side close to the regulating member 28. Is possible. By configuring the buffer member 30 in this manner, it is possible to suppress the displacement of the glass plate laminate 3 due to an impact such as vibration during transportation and to absorb the impact on the glass plate laminate 3.

On the other hand, by forming the first buffer layer 30a on the side close to the lower end of the glass plate laminate 3 with a material softer (lower elastic modulus) than the second buffer layer 30b on the side close to the regulating member 28, to the end face. It is possible to reduce a direct impact on a thin glass substrate (for example, 0.5 mm or less) that is particularly vulnerable to the impact. Moreover, even if the glass plate laminate 3 is displaced in the width direction by disposing the relatively hard buffer layer 30b on the regulating member 28 side, the amount of displacement (amount of movement in the width direction). Can be suppressed.

In the above description, in addition to the regulating member 28, the support portion 29, and the buffer member 30, the holding bar 14 having a pair of projecting

portions

21 a and 21 b and the side stopper 15 having a pair of projecting

portions

22 a and 22 b are provided. Although the glass plate packing pallet 2 has been illustrated, it is of course possible to adopt other configurations. That is, the regulating member 28, the support portion 29, and the buffer member 30 are attached to the glass plate packing pallet 2 having the pressing bar 14 and the side stopper 15, in which the pair of protruding

portions

21 a and 21 b (22 a and 22 b) are omitted, and the glass It is also possible to use the plate package 1. Alternatively, it is also possible to provide the regulating member 28, the support portion 29, and the buffer member 30 on a glass plate packing pallet that can fix the glass plate laminate 3 by a fixing means other than the belt 13.

Moreover, in the above description, the case where it laminated | stacks through the slip sheet I between the glass plates G was illustrated (FIG. 1 etc.), Of course, also when the slip sheet I is abbreviate | omitted and only the glass plate G is laminated | stacked. It is possible to apply the glass plate packing pallet according to the present invention.
