Bundle and bale container

This creation relates to a packaging container and a package body in which a plurality of glass sheets are placed upright in a packaging container.

In recent years, there has been an increase in demand for large glass sheets used for glass for FPD. As a mechanism for transporting such a large-sized glass plate, for example, a glass plate packing case in which each glass plate is fixed in a state in which a plurality of glass sheets are erected is known (for example, Patent Document 1).  The glass plate packing box has a base on which the glass plate is placed, and has a backing plate that supports the bottom plate of the lower end portion of the glass plate and the thickness direction of the supporting glass plate on the mounting surface of the base plate. Composition.  

When the glass plate is mounted on the bottom plate and the back plate, the spacer paper is usually sandwiched between the glass plates in order to prevent damage to the glass plates during direct contact with each other during transportation. At this time, in order to facilitate the unloading of the glass sheet, the spacer paper is conveniently held by the mechanical arm and removed from the glass sheet, and the spacer paper is previously extended from the upper end of the glass sheet as a holding portion for holding and holding by the robot arm.  In Patent Document 1, in view of the fact that the holding portion of the spacer paper, that is, the portion extending from the upper end of the glass sheet is not inclined upright or inclined in the opposite direction, the positioning of the mechanical arm to the holding portion cannot be performed well and cannot be adsorbed. The problem of the spacer paper is maintained such that the spacer paper extending from the upper end of the glass sheet is inclined in the same direction as the backing plate of the glass sheet packing case.  [Previous Technical Literature]  [Patent Literature]

According to the present package and the packaging container, the extension of the spacer paper can be held by the comb member, and the inclination of the spacer paper can be suppressed.

Hereinafter, the first embodiment of the package of the present invention will be described, but the present invention is not limited to the embodiment described below.

1(a) and 1(b) are views showing a schematic configuration of an embodiment of the packaged body of the present invention, and Fig. 1(a) is a front view, and Fig. 1(b) is a side view. In Fig. 1, reference numeral 1 denotes a package body, and the package body 1 is composed of a package container 2 having a comb member 12 and a glass plate G mounted on the package container 2.

The glass plate G is intended to be a glass substrate for a flat panel display (FPD) such as a liquid crystal device, an EL device, or a plasma display device. Specifically, for example, a rectangular plate-shaped glass substrate having a size of about 2,500 mm × 2,200 mm and a thickness of about 0.3 to 0.7 mm is used as the glass plate G. However, the present invention is not limited to the fixation of the glass sheet G of such a size, and can be applied to the fixing of the glass sheets of various sizes or thicknesses. Further, various glass sheets other than the glass substrate for FPD are also suitable for use.

The packaging container 2 is provided with an upright placement type packaging container in which the glass sheet G is mounted in an upright position, and includes a base 3, a bottom stack 4 disposed on the base 3, a backing plate 5, and a comb member 12. The base 3 is placed on a substantially horizontal surface of a floor or a loading dock of a vehicle, and as shown in Fig. 1(a), a plurality of (four in the figure) are formed on the front side and the back side. The opening 6 of the lifter claw (not shown) is inserted and removed. The side surface of the base 3 may be opened or may have a closed structure (closed structure in Fig. 1(b)). Further, the base 3 includes, for example, a steel material. However, stainless steel is preferred in view of preventing peeling of the coating in consideration of the case of moving into the clean room.  In the present specification, "upright placement" means that the glass sheet is placed in a state of being inclined by 30 or more with respect to the horizontal plane.  

The bottom stack 4 is provided in a rectangular plate shape provided on the upper surface 3a of the base 3, and supports the bottom edge portion of the mounted glass plate G. The bottom stack 4 is disposed on the base 3 via the backsheet 7 as shown in Fig. 1(b), and is disposed obliquely to the upper surface 3a of the base 3. Further, in the present embodiment, the bottom stack 4 is provided at two locations in the width direction of the base 3, and the upper surface (inclined surface) of each of the bottom stacks 4, that is, the mounting surface of the glass sheet G is arranged to constitute the same plane. The surface of the bottom stack 4 is substantially flat without forming a groove for inserting the glass sheet G, and may be a wave as long as the plurality of glass sheets G are placed with the spacer P interposed therebetween. Shaped or rough.

Further, the bottom stack 4 may be composed of one sheet having the same length as the width of the back sheet 5 to be described later. The bottom stack 4 is preferably inclined by 5 to 25 degrees, more preferably 10 to 20 degrees, and more preferably about 18 degrees with respect to the upper surface 3a of the base 3. Thereby, the operator can easily and efficiently perform the positioning operation of the glass sheet G when the glass sheet G is placed. Since each of the glass sheets G is in contact with the glass sheet G on the side of the back sheet 5 by its own weight, no useless gap is generated between the glass sheets G. Further, it is possible to stabilize the glass plate G placed thereon, prevent the glass plate G from being displaced or collapsed, and prevent damage or chipping. Alternatively, the film 7 may have a height adjustment function, and the angle adjustment of the bottom stack 4 with respect to the upper surface 3a of the base 3 may be adjusted.

The back plate 5 supports one side of the support frame 8 fixed to the upper surface 3a of the base 3, and the lower end portion is fixed to the bottom stack 4. The support frame 8 includes a stay 9 that is disposed to rise upward with respect to the upper surface 3a of the base 3, a tilt frame 10 that is disposed at a predetermined angle with respect to the upper surface 3a of the base 3, and is disposed on the support and the tilt The reinforcing frame 11 between the frames 10 is constructed.

The inclined frame 10 is provided with a plurality of roots on the upper surface 3a of the base 3 so as to be 90 to 100 degrees, and more preferably 90 degrees with respect to the upper surface of the bottom stack 4. Further, the pillars 9 are also provided with a plurality of roots corresponding to the inclined frame 10. The reinforcing frame 11 is provided with a plurality of roots on the upper surface 3a of the base 3 and at the central portion in the height direction of each of the support column 9 and the inclined frame 10.

Further, the back plate 5 is attached to the outer side of the inclined frame 10 including the support frame 8 having such a configuration, and thus is inclined at the same angle as the inclined frame 10. The back sheet 5 is formed to support a rectangular plate shape which is placed on one side of the glass sheet G which is placed upright on the bottom stack 4, and is formed to be slightly larger than the glass sheet G to be mounted.

In order to prevent the back sheet 5 and the bottom stack 4 from being damaged by contact with the glass sheet G when the glass sheet G is mounted, rubber or hard foam is attached to the surface (the side contacting the glass sheet G). A cushioning material C such as a resin.

The glass plate G is stacked, for example, in a range of from 100 pieces to 800 pieces, and is vertically stacked in the direction before and after the bottom stack 4, that is, in a direction orthogonal to the outer surface of the back plate 5. Further, a rectangular sheet of space P is sandwiched between each of the glass sheets G.  The spacer paper P is used to prevent the glass sheets G from directly contacting each other and to prevent the glass sheets G from interfering with each other during transportation.  

As shown in FIG. 1(b), the spacer paper P is larger than the glass sheet G. Therefore, at least the upper end portion extends upward from the upper side of the glass sheet G to form the extending portion PE when the glass sheet G is placed. Further, in the present embodiment, the left and right sides of the glass sheet G are also in a state in which the spacer P is over (extended) (not shown). The length of the extending portion PE extending above the glass sheet G is, for example, about 50 to 80 mm.

Further, as shown in Fig. 2(a), the lower end PL of the spacer paper P is placed from the upper surface (mounting surface) of the bottom stack 4 by, for example, 10 mm or less, preferably about 5 mm. Thereby, when the spacer paper P and the glass sheet G are alternately arranged on the bottom stack 4 from the side of the back sheet 5, the lower end portion of the spacer paper P can be prevented from expanding to the bottom stack 4, thereby preventing the glass sheet G from being placed on the expanded sheet. On the spacer paper P. When the glass sheet G is placed on the spacer paper P, the movement of the glass sheet G on the bottom stack 4, that is, the sliding of the glass sheet G by its own weight, and the unloading of the glass sheet G are also affected.

The comb member 12 is a comb member as shown in FIG. In the present embodiment, as shown in FIG. 2(b), the comb teeth of the comb member 12 are inserted between the extending portions PE of the spacer paper P, and the extending portion PE of the spacer P is held. By fixing the comb member 12 to the upper portion of the backing plate 5, the extending portion PE is kept in a state of straight extension without being inclined.

The material of the comb member 12 is not particularly limited, and for example, an acrylic or polycarbonate resin or the like can be used.  The length of the comb tooth may be adjusted so as not to contact the end portion of the glass plate G when the comb member 12 holds the extending portion PE and is fixed to the back plate 5, and may be damaged, for example, 50 mm. about. The length of the comb teeth can also be 20 mm to 80 mm.  The thickness of the comb teeth is, for example, about 2 mm, and the gap between the comb teeth is, for example, about 6 mm. The gap between the comb teeth is preferably, for example, an extension portion PE of the spacer P which holds about 10 to 20 sheets. The thickness of the comb teeth can also be 0.5 mm to 3 mm, and the gap between the comb teeth can be 3 mm to 15 mm.  Moreover, in order to facilitate insertion of the comb teeth between the extending portions PE of the spacer paper P, it is preferable to set the tip end of the comb teeth to a tapered shape.  

The method of fixing the comb member 12 to the backing plate is not particularly limited. For example, as shown in FIG. 2(b) and FIG. 3, the magnet 12a attached to the comb member can be fixed to the backing plate 5.  The number of the comb members 12 to be fixed to the back sheet is not particularly limited as long as the size of the spacer paper P is appropriately increased or decreased.  

Further, in the package body 1 of the present embodiment, the glass sheet G and the spacer paper P are alternately disposed on the packaging container 2 as shown in Fig. 1(b), and the extension portion of the spacer paper P is held by the comb member 12. PE, after the comb member 12 is attached to the backing plate 5, the glass plate G is fixed by various fixing tools (not shown) known in the prior art, and the resin sheet is coated as needed, or stored in a packing box or the like, and formed. The final form of transportation, etc.

For example, the glass plate G is fixed to the packaging container 2 by using the glass plate pressing member 13 as shown by the two-dot chain line in FIG. 1(b). The glass plate pressing member 13 is formed by the front frame 14 and the side frame 15, and the side frame 15 is attached to both sides of the support frame 8, and the front frame 14 is attached to the front part of the side frame 15. The glass plate pressing member 13 can be detachably attached to the front frame 14 with respect to the side frame 15, or the side frame 15 can be detachably attached to the support frame 8, and the glass plate G can be housed in the glass plate pressing member 13.

Further, the glass plate pressing member 13 may be provided with an air bag 16 inside the front frame 14. The glass sheet G can be surely fixed by pressing the glass sheet G by the airbag 16. As such an airbag 16, it is preferable to press and fix the glass plate G by adjusting the amount of air and expanding it appropriately. For the airbag 16, any one can be prepared as needed.  Further, as the fixture of the glass sheet G, it is preferable to provide a side pressing member (not shown) that fixes the side portion of the glass sheet G.  

Next, a method of forming the package body 1, that is, a packing method will be described.  First, the glass plate G and the spacer paper P are alternately arranged on the bottom stack 4 of the packaging container 2 shown in FIG. 1(b), whereby a plurality of glass sheets G are placed on the bottom stack 4, and the spacer paper is placed. P is sandwiched between the glass sheets G. The placement of the glass sheet G on the bottom stack 4 is performed in the same manner as before by a dedicated robot arm (not shown). Further, the arrangement of the spacer paper P on the glass sheet G is also performed in the same manner as in the prior art by a dedicated robot arm (not shown). At this time, as shown in FIG. 2(a), the spacer paper P is disposed such that the lower end PL of the spacer paper P is lifted by, for example, about 5 mm from the bottom stack 4. Further, as shown in Fig. 2(b), the upper end portion is extended from the upper side of the glass sheet G by about 50 to 80 mm to form the extending portion PE.  

After the specific number of glass sheets G are mounted on the bottom stack 4 as described above, and the spacer paper P is sandwiched between the glass sheets G, the comb teeth of the comb member 12 are inserted into the spacer paper P. The portion PE holds the extension portion PE of the spacer paper P, and thereafter the comb member 12 is fixed to the back sheet 5.

Thereafter, the glass sheet G is fixed to the packaging container 2 by a glass plate pressing member 13 or the like as shown by a two-dot chain line in FIG. 1(b), and the resin sheet is coated on the glass sheet G or the like as necessary. In the same manner as before, the final form for transportation or the like is formed.

Next, the discharge of the glass sheet G of the package body 1 thus formed will be described.  First, a resin sheet or the like or other fixtures are removed from the bale container 2 in the same manner as before.  Next, the comb member is removed from the backing plate.  Next, unloading of the glass sheet G from the bottom stack 4 and removal of the spacer paper P from the glass sheet G are performed. The unloading of the glass sheet G from the bottom stack 4 is performed in the same manner as before by a dedicated robot arm (not shown). For example, the outer surface of the glass sheet G (the surface opposite to the back sheet) is suction-held by a mechanical arm having a hole for suction or a suction cup, and is transferred to a transfer device such as a conveyor.  

Further, the removal of the spacer paper P from the glass sheet G is also performed in the same manner as in the prior art by a dedicated robot arm. For example, after the outermost glass sheet G is removed, the spacer paper P exposed on the outermost surface is held by a robot arm and transferred to a transfer device such as a conveyor.

According to the above-described packing method, since the extending portion PE of the spacer P is held by the comb member 12 and the comb member 12 is fixed to the backing plate 5, the extending portion PE of the spacer P is held in a straight state. Therefore, the extension portion PE can be favorably held by the robot arm at the time of unloading, and the paper P can be stably removed from the glass sheet G by stabilizing the spacer paper P.

Further, the comb member 12 is provided with the magnet 12a, and the magnet 12a is fixed to the backing plate 5, whereby the fixing and removal of the comb member 12 to the backing plate 5 can be easily performed.

When the spacer paper P is sandwiched between the glass sheets G, the spacer paper P is placed in a state in which the lower end is floated from the bottom stack 4 as shown in Fig. 2(a). When the glass sheet G and the spacer paper P are alternately arranged on the stack 4 from the side of the back sheet, the lower end portion of the spacer paper P can be prevented from expanding on the bottom stack 4, and the glass sheet G can be prevented from being placed on the expanded spacer P.

Further, according to the above-described package body 1, since the extending portion PE of the spacer paper P is held in a straight state by the comb member 12 fixed to the backing plate 5, the extension by the robot arm can be favorably performed at the time of unloading. The portion PE is held, so that the spacer P can be stabilized and reliably removed from the glass sheet G.

The present invention has been described in detail with reference to the specific embodiments thereof, and it is understood that various changes and modifications can be made without departing from the scope of the invention.  The present application is based on Japanese Patent Application No. 2018-001, filed on Mar.  [Industrial availability]
