Thereby, even if the upper extension of the protective sheet is about to fall backward, the protrusion can push the upper extension from the rear surface side to force the upper extension to stand up and/or to force the upper extension The out part fell to the front side. Therefore, it is possible to prevent the upper side extension from falling backward. As a result, it is possible to avoid the occurrence of failure to take out the protective sheet due to the overhanging portion falling backward.

In the above structure, it is preferable that the direction in which the upper edge of the glass plate extends is the width direction, and the protrusions are arranged to face the rear surface at both ends of the upper extension in the width direction, respectively.

If this is the case, the protrusions are arranged at both ends in the width direction of the upper extension. Therefore, when the glass sheet package is opened, the device for taking out the glass sheet from the laminate, the device for taking out the protective sheet, and the Protrusions may interfere.

In the above structure, it is preferable that the protrusions are configured to be attachable and detachable with respect to the support surface. As positions where the protrusions can be attached, a plurality of locations are provided on the support surface, and the plurality of portions are located in the vertical direction at intervals and / Or provided at intervals in the width direction.

The arrangement of the part to prevent the upper extension part from falling backward. [Effects of the invention]

According to the present invention, when the glass plate package is opened and the glass plate and the protective sheet are taken out from the laminate, it is possible to avoid the occurrence of failure to take out the protective sheet.

Hereinafter, the glass plate package according to the embodiment of the present invention will be described with reference to the accompanying drawings. Here, in each drawing referred to in the description of the embodiment, the direction in which the upper edge of the glass plate extends (the width direction of the glass plate) is expressed as the X direction, and the vertical direction is expressed as the Y direction. The X direction, the Y direction, and the Z direction are directions orthogonal to each other.

As shown in FIG. 1, the glass plate package 1 (hereinafter only referred to as the package 1) includes a pallet 2 and a laminate 3 mounted on the pallet 2.

The laminate 3 includes a rectangular glass plate G and a rectangular backing paper P as a protective sheet. The glass plate G and the backing paper P are alternately laminated in the front-rear direction (direction inclined with respect to the Z direction) in an inclined posture inclined with respect to the vertical direction (Y direction). The backing paper P is arranged at the rear of the layered body 3.

Here, an example of the specifications of the laminate 3 is given. The number of glass plates G constituting the laminate 3 is 100 to 400, and the size of the glass plate G (length×width) is 1000 mm×1200 mm to 2900 mm× 3200 mm, the thickness of the glass plate G is 0.2 mm to 2 mm. The interleaving paper P constituting the layered body 3 is a so-called glass interleaving paper, for example, pure pulp paper. The backing paper P has a size larger than the glass plate G (refer to FIG. 2). Furthermore, as a protective sheet, a foamed resin sheet can also be used.

The pallet 2 mainly includes a base part 4, a rear surface support part 5, a bottom surface support part 6, a holding part 7, a buffer plate 8, and a support plate 9.

The base part 4 is formed with a hole 4a into which a fork of a stacker or the like is inserted. The rear surface support part 5 stands up from the base part 4 and supports the rear surface of the laminated body 3 via the buffer plate 8. Thereby, the front surface 8a of the buffer board 8 functions as a support surface which supports the laminated body 3 from the back side. The bottom surface support portion 6 supports the bottom surface of the laminate 3 (the lower side Gb of each glass plate G) on the base portion 4 via the support plate 9.

The dimension in the X direction of the buffer plate 8 is smaller than the dimension in the X direction of the front surface 5a of the rear surface support portion 5, and the buffer plate 8 is mounted on the front surface 5a except for the upper edge and both side edges. The area of the glass plate G and the backing paper P is smaller than the area of the front surface 8 a of the buffer plate 8, and the peripheral edge portion of the buffer plate 8 is in a state of protruding from the laminate 3.

The front surface 5a of the rear surface support part 5 and the front surface 8a of the buffer plate 8 are inclined to the rear by a predetermined angle (for example, 5° to 25°) with respect to the vertical direction (Y direction). The two front surfaces 5a, 8a and the upper surface 6a of the bottom support portion 6 (the upper surface 9a of the support plate 9) form a substantially right angle (for example, 90°±10°), for example.

The buffer plate 8 and the support plate 9 include, for example, an elastic material such as foam or rubber. In this embodiment, both the buffer plate 8 and the support plate 9 are made of foamed polypropylene as a main material.

The holding part 7 mainly includes a belt 10, a pressing rod 11, and a side stopper 12.

The belt 10 is a ratchet belt including a ratchet portion 13. The belt 10 is hooked on a hook 14 arranged behind the rear surface support part 5 to form a double layer, and then the front surface of the pressing lever 11 is fastened by a ratchet part 13.

The pressing plate 15 is arranged on the front side of the laminated body 3, and the frame 16 is arranged on the further front side of the pressing plate 15. A hook 17 is provided on the frame 16, and a pressing rod 11 is placed on the hook 17. As the belt 10 is tightened, the pressing rod 11 presses the frame 16 to the rear side, and the frame 16 presses the pressing plate 15 to the rear side. Thereby, the laminated body 3 is fixed to the pallet 2 in the state pressed by the buffer board 8.

The pressing rod 11 is combined with the belt 10 so that the longitudinal direction thereof becomes the X direction. In the present embodiment, the two pressing rods 11 are arranged up and down with an interval therebetween.

In addition, the said holding part 7 is an example, as long as the laminated body 3 can be fixed to the pallet 2, the holding part 7 of another structure may be used.

As shown in FIG. 2, the interleaving paper P protrudes from the upper side Ga and both sides Gc and Gc of the glass plate G, respectively. On the other hand, the backing paper P does not protrude from the lower edge Gb of the glass plate G, and the lower edge Gb of the glass plate G and the backing paper P are at the same position. Furthermore, the lower edge Gb of the glass plate G may also protrude from the lower edge of the backing paper P. In the following description, the portion of the interleaving paper P projecting from the upper edge Ga of the glass plate G is referred to as the upper edge extension Pa. In addition, in FIG. 2, for convenience of description, only the glass plate G and the backing paper P which are arranged on the rearmost side among the plurality of glass plates G and the plurality of backing papers P constituting the laminated body 3 are shown.

As shown in FIGS. 2 and 3, the protrusion 18 protrudes from the front surface 8 a of the buffer plate 8 to the front side. The protruding portion 18 is arranged above the upper edge Ga of the rearmost glass plate G, and faces the rear surface Paa of the upper edge extension Pa of each backing paper P constituting the layered body 3. In this embodiment, the protrusions 18 are paired in the X direction, and the two protrusions 18 and 18 of the pair are opposite to the rear surface Paa at both ends of the upper extension Pa in the X direction. That is, the pair of two protrusions 18 and 18 are arranged corresponding to the upper corners of the rectangular shape formed by the backing paper P, respectively. In this embodiment, the outer shape of the protrusion 18 is formed in a rectangular parallelepiped shape.

Here, regarding the protrusion 18, the length L protruding from the front surface 8a of the buffer plate 8 is preferably set to 10 mm or more from the viewpoint of easy attachment and detachment work described later. From the viewpoint of reliably preventing the upper extension Pa from falling to the rear side, when the thickness of the layered body 3 is set to t (mm), the length L (mm) is preferably set to 0.2t to 0.8t . The protrusion 18 can include materials such as rubber, resin, and foam. However, it is not limited to this, as long as it is a material which is not damaged when it contacts the glass plate G, you may comprise the protrusion part 18 with another material. In addition, the outer shape of the protrusion 18 may not be a rectangular parallelepiped, for example, it may be cylindrical, triangular columnar, polygonal columnar, hemispherical, semi-elliptical, or conical, triangular pyramidal, or polygonal pyramidal. It may also be a strip extending in the X direction.

In addition, when the package 1 is opened and the glass plate G and the backing paper P are alternately taken out from the laminated body 3, when taking out the backing paper P, a robot or the like including a suction pad is often used. In addition, the area on the inner side of the corner of the upper extension Pa of the backing paper P is adsorbed by the suction pad included in the robot from the front side (area located between the pair of two protrusions 18, 18) .

The protrusion 18 is configured to be attachable to and detachable from the front surface 8 a of the buffer plate 8. The position indicated by the cross mark in FIG. 4 is a position where the protrusion 18 can be attached, and a plurality of positions where the protrusion 18 can be attached are provided on the front surface 8a. These multiple locations are provided at intervals in the up-down direction and the X-direction. Thereby, even when the size of the glass plate G or the backing paper P constituting the laminate 3 is changed, by changing the arrangement of the protrusions 18 accordingly, the protrusions 18 can be formed with the backing paper P. The upper corner of the rectangular shape corresponds to the configuration.

Here, regarding the protrusion 18, a structure that can be attached to and detached from the front surface 8a of the buffer plate 8 is exemplified. As an example of the structure, a structure in which the protrusion 18 is formed as a rod-shaped member, a part of the rod-shaped member is fitted into a hole formed in the buffer plate 8, and the other part is formed from the front surface 8a. The way of protruding is exposed from the buffer plate 8.

Hereinafter, the main functions and effects based on the package 1 will be described.

In the above-mentioned packing body 1, the protrusion 18 protrudes to the front side than the front surface 8a of the buffer plate 8 which supports the laminated body 3 from the back side. Thereby, even if the upper extension Pa of the backing paper P is about to fall to the rear side, as shown in FIG. 3, the protrusion 18 can push the upper extension Pa from the rear surface Paa side to force the upper extension to extend. The part Pa stands up and/or the upper extension Pa is forcibly tilted forward. Therefore, it is possible to prevent the upper extension Pa from falling backward. As a result, it is possible to avoid the occurrence of failure to take out the backing paper P due to the overhanging portion Pa falling backward. In addition, when there is no protrusion 18, the upper side extension Pa of the backing paper P existing on the front side of the layered body 3 is more likely to fall to the rear side.

Here, the glass plate package of this invention is not limited to the structure demonstrated in the said embodiment. For example, in the above-mentioned embodiment, the pair of two protrusions 18 and 18 are respectively arranged corresponding to the upper corners of the rectangular shape formed by the backing paper P, but it is not limited to this. The protrusion 18 may be arranged corresponding to the two corners on the upper side instead of being arranged corresponding to the corners on the upper side. Alternatively, in addition to the arrangement corresponding to the upper corners, the upper corners may also be arranged corresponding to each other.

Furthermore, in the above-mentioned embodiment, the protrusion 18 is attached to the front surface 8a of the buffer plate 8, but it is not limited to this. The condition required for the protrusion 18 is to face the rear surface Paa of the upper extension Pa, and to be more oriented than the support surface (the front surface 8a of the buffer plate 8 in the embodiment) that supports the laminate 3 from the rear side The front side protrudes. Therefore, as long as this condition is satisfied, for example, the protrusion 18 can be attached to a member different from the front surface 8a of the buffer plate 8 and independent of the front surface 8a.
