Description

The present invention relates to a glass sheet transport unit, and more particularly to a glass sheet transport unit comprising a packaging pallet on which a glass sheet laminate is loaded, and a transport container.

As is well known, in the field of glass plate packaging, glass plate laminates in which multiple glass plates and interleaf paper or the like are arranged alternately are loaded onto a packaging pallet. Furthermore, when transporting these glass plates, the glass plate laminates are loaded onto a packaging unit, and the resulting glass plate package is placed inside a transport container.

During transport using this transport container, the packaging pallet needs to be fixed inside the transport container. For example, Patent Document 1 discloses a method for doing so, in which a lashing belt is hung over the top of the packaging pallet and both ends of the belt are fixed to the bottom (floor) inside the transport container.

JP 2014-122074 A

However, as disclosed in Patent Document 1, the method of fixing both ends of the lashing belt to the floor inside the transport container creates a problem of space required to fix the packaging pallet, since packaging pallets are currently becoming larger as glass sheets become larger.

Moreover, according to the method disclosed in the document, a long lashing belt is required because the lashing belt is hung over the top of the packaging pallet and both ends are fixed to the floor surface inside the transport container. In light of the current situation in which packaging pallets are also becoming larger in size in line with the increase in size of glass sheets, the lashing belt will have to be made even longer. This makes it difficult to maintain the packaging pallet in a stably fixed state against vibrations and shaking during transport.

In view of the above, the present invention aims to provide a glass sheet transport unit that can avoid space problems associated with fixing a packing pallet within a transport container and can maintain the packing pallet in a stably fixed state against vibrations and shaking during transport.

The present invention, which was invented to solve the above problems, is a glass plate transport unit comprising a packing pallet on which a glass plate laminate having a plurality of glass plates is loaded, and a transport container in which a glass plate package obtained by loading the glass plate laminate onto the packing pallet is housed, and is characterized in that it comprises a fastener for fixing the packing pallet to the upper part inside the transport container.

With this configuration, even if the glass sheet package becomes larger as the glass sheets become larger, the upper part of the transport container, where there is free space, can be effectively used to secure the packing pallet. This avoids space issues when securing the packing pallet inside the transport container. Moreover, the length of the fasteners is sufficient as long as they can reach the upper part of the transport container from the packing pallet, so the packing pallet can be kept stably secured against vibrations and shaking during transport.

In this configuration, it is preferable that within the transport container, the glass sheet laminate is loaded onto the packaging pallet in an inclined position inclined between the two side walls of the transport container.

In this way, even large glass panels that are larger than the height and width dimensions of the container's internal space can be accommodated.

In this configuration, it is preferable that the first end of the fixing device is fixed to a corner portion between one side wall located on the front side of the glass sheet laminate within the transport container and the ceiling wall.

In this way, the large open space formed on the front side of the glass sheet laminate inside the transport container is located near the corner where the first end of the fastener is fixed. Therefore, when a worker or the like fixes the first end of the fastener to the corner, the glass sheet laminate does not get in the way due to the presence of that large open space. This improves the work efficiency when performing the fixing work.

In this configuration, it is preferable that the first end of the fixing device is located on the front side of the glass sheet laminate within the transport container.

This prevents the stack from coming into contact with the belt when the first end of the fastener is fixed to a corner of the transport container via a belt or the like. This prevents the glass sheets in the stack from being damaged due to contact with the belt.

In the above configuration, the packaging pallet may have a rear support portion that supports the glass plate laminate from the rear side, and the second end of the fixing device may be fixed to the rear support portion.

In this way, the second end of the fastener can be fixed by effectively using the back support part, which is the most rigid part of the packaging pallet. This allows the second end of the fastener to be firmly fixed, ensuring a stable fixed state.

In the above configuration, the packaging pallet may have a base portion arranged on the bottom side of the glass plate laminate, and the second end of the fixing device may be fixed to the base portion.

In this way, the second end of the fastener can be fixed by effectively using the base, which is the most rigid part of the packaging pallet. This allows the second end of the fastener to be firmly fixed, ensuring a stable fixed state.

In the above configuration, it is preferable that the fixing device is made of metal.

In this way, the rigidity of the fastening device is significantly increased compared to conventional lashing belts, etc., and loosening of the fastening device during transportation is prevented.

According to the present invention, it is possible to provide a glass sheet transport unit which can avoid space problems for fixing a packing pallet within a transport container and can maintain the packing pallet in a stably fixed state against vibrations and shaking during transport.

Below, a glass plate transport unit relating to an embodiment of the present invention is described with reference to the attached drawings.

The glass sheet transport unit 1 according to this embodiment is a glass sheet transport unit 1' shown in Figures 1 and 2 to which a characteristic configuration has been added. Here, we will first explain the glass sheet transport unit 1' before the characteristic configuration has been added. Note that Figure 1 is a vertical front view showing the glass sheet transport unit 1', and Figure 2 is a vertical side view cut along line A-A in Figure 1.

As shown in these figures, the glass sheet transport unit 1' includes a packing pallet 3 on which a glass sheet laminate 2, in which a plurality of glass sheets G and interleaf paper (which may be a resin sheet) H are alternately arranged, is loaded, and a transport container 5 in which a glass sheet package 4 obtained by loading the glass sheet laminate 2 on the packing pallet 3 is housed. The size (lengthwise dimension x widthwise dimension) of the glass sheet G is large, for example, 2200 mm x 2500 mm or more. The size of the glass sheet G is preferably 2400 mm x 2800 mm or more, more preferably 2800 mm x 3100 mm or more, and most preferably 2900 mm x 3300 mm or more.

The main components of the packaging pallet 3 are a base 6 that is placed on the bottom side of the glass sheet laminate 2 to support its weight, a rear support 7 that stands on the top of the base 6 and supports the glass sheet laminate 2 from the rear side, and a pedestal 8 that is fixed to the top of the rear support 7 and on which the glass sheet laminate 2 is placed. The lower end of the pedestal 8 is located lower than the upper end of the base 6.

The base 6 has a rectangular frame 6a in plan view and multiple reinforcing members (not shown) made of square pipes or the like that reinforce the frame 6a. The rear support 7 has multiple crosspiece members 7a made of square pipes or the like that are arranged below the pedestal 8 and form a framework. The pedestal 8 has an upper pedestal 8a that receives the flat surface of the glass sheet laminate 2 and a lower pedestal 8b that receives the bottom surface of the glass sheet laminate 2.

The transport container 5 has an internal space (storage section) N with a rectangular vertical front view, and this internal space N is surrounded by a bottom wall 5A, a ceiling wall 5B, two side walls 5C, 5D, and an end wall 5E. The height (distance from the bottom wall 5A to the ceiling wall 5B) of the internal space N of the transport container 5 is about 2660 mm, and the width (distance between the two side walls 5C, 5D) is about 2340 mm. The transport container 5 is provided with an entrance (not shown) for carrying in and carrying out the glass sheet package 4 on the side opposite to the depth direction (arrow B direction) shown in FIG. 2. A plurality of glass sheet packages 4 are arranged in the internal space N.

The relationship between the glass sheet package 4 and the transport container 5 is as follows. The glass sheet laminate 2 is loaded on the packing pallet 3 in an inclined position between the two side walls 5C, 5D of the transport container 5, that is, the inclined position shown in FIG. 1. This glass sheet laminate 2 (upper base portion 8a) is in a position that follows the diagonal of the internal space N of the transport container 5. In detail, the inclination angle of the glass sheet laminate 2 with respect to the horizontal plane is preferably 10° or less larger than the inclination angle of the diagonal of the internal space N of the transport container 5 with respect to the horizontal plane, and more preferably 5° or less larger than the inclination angle of the diagonal of the internal space N of the transport container 5 with respect to the horizontal plane. The gap between the side walls 5C, 5D of the internal space N of the transport container 5 and the base portion 6 is, for example, 10 to 30 mm.

A locking member 9 such as a hook is attached to the corner X between the side wall 5C (its inner surface) located on the front side of the glass sheet laminate 2 and the ceiling wall 5B (its ceiling surface). The packaging pallet 3 is placed on the bottom wall 5A (its floor surface) of the transport container 5.

[First embodiment]
Fig. 3 is a longitudinal sectional front view showing the glass sheet transporting unit 1 according to the first embodiment of the present invention to which a characteristic configuration has been added, and Fig. 4 is a longitudinal sectional side view cut along line CC in Fig. 3. Note that components common to this glass sheet transporting unit 1 and the glass sheet transporting unit 1' illustrated in Figs. 1 and 2 are given the same reference numerals in Figs. 3 and 4, and detailed descriptions thereof will be omitted.

As shown in Figures 3 and 4, the glass sheet transport unit 1 is equipped with a fixing device 10 that fixes the packing pallet 3 to the upper part inside the transport container 5. In this embodiment, the fixing device 10 connects and fixes a locking member 9 attached to a corner portion X inside the transport container 5 to the back support portion 7 of the packing pallet 3. Therefore, the fixing device 10 has an upper end portion 10a as a first end portion fixed to the locking member 9 of the corner portion X, and a lower end portion 10b as a second end portion fixed to the back support portion 7.

In more detail, the fixture 10 comprises a framework 11 fixed to the lower rear part of the rear support part 7, and a rod-shaped body 12 extending in a straight line from the framework 11 toward a corner part X inside the transport container 5. The framework 11 is detachably fixed to a plurality of rail members 7a of the rear support part 7 using fastening members such as bolts. The lower end of the rod-shaped body 12 is fixed to the framework 11 by welding or the like, and its upper end (first end) 10a is detachably fixed to the locking member 9 by metal fittings, a high-strength belt, or the like.

The rear support part 7 protrudes from one widthwise end part 2a (the right widthwise end part in FIG. 4 ) of the glass sheet laminate 2, and the framework body 11 of the fixing device 10 is fixed to this protruding part 7x. The framework body 11 and the rod-shaped body 12 are made of a metal such as iron or stainless steel, and the locking member 9 is also made of a metal such as iron or stainless steel.

Next, the function and effect of the glass sheet transport unit 1 relating to this first embodiment will be explained.

In this embodiment, since the glass sheet G is large, the glass sheet package 4 is also large, so the gap between the side walls 5C, 5D of the internal space N of the transport container 5 and the base part 6 is small, and there is not enough free space on the bottom wall 5A (on the floor surface) in the transport container 5. Therefore, it is difficult to fix the packaging pallet 3 on the bottom wall 5A. In contrast, in this embodiment, a large free space S exists on the front side of the glass sheet laminate 2. This free space S is located near the attachment point of the locking member 9. Therefore, due to the presence of this free space S, the worker can connect and fix the upper end 10a of the fixing device 10 to the locking member 9 without being hindered by the glass sheet laminate 2. This improves the work efficiency when fixing the upper end 10a of the fixing device 10.

In this embodiment, because the glass sheet stack 2 is in the inclined position described above, even large glass sheets G that are larger than the height and width dimensions of the internal space N of the transport container 5 can be accommodated.

In this embodiment, the lower end 10b of the fixing device 10 is fixed by effectively utilizing the back support portion 7, which is a highly rigid portion of the packing pallet 3. Moreover, the lower end 10b of the fixing device 10 is formed of a highly rigid framework body 11. This synergistic effect allows the lower end of the fixing device 10 to be firmly fixed, ensuring a stable fixed state.

In this embodiment, unlike conventional long lashing belts, the length of the fixing device 10 is sufficient as long as it can reach from the back support part 7 of the packing pallet 3 to the corner part X inside the transport container 5. Moreover, since the fixing device 10 is made of metal, the rigidity of the fixing device 10 is significantly increased compared to conventional lashing belts. These synergistic effects allow the packing pallet 3 to be kept stably fixed against vibrations and shaking during transport.

[Second embodiment]
FIG. 5 is a longitudinal front view showing a glass sheet transport unit 1 according to a second embodiment of the present invention to which a characteristic configuration has been added, and FIG. 6 is a longitudinal side view cut along line D-D in FIG.

As shown in these figures, the glass sheet transport unit 1 according to the second embodiment differs from that according to the first embodiment in that the lower end 10b of the fixture 10 is fixed to the base 6. In detail, the frame 6a of the base 6 protrudes from one end 2a in the width direction of the glass sheet laminate 2 (see FIG. 6), and the framework 11 of the fixture 10 is detachably fixed to the side of the protruding portion 6x via a bracket 13. The lower end 10b of the fixture 10 may be detachably fixed to the upper surface of the protruding portion 6x. Since the other configurations and effects are the same as those of the first embodiment, the same reference numerals are used in FIG. 5 and FIG. 6 for the components common to both embodiments, and their explanations are omitted.

The above describes a glass sheet transport unit 1 according to an embodiment of the present invention, but the present invention is not limited to this and various variations are possible without departing from the gist of the invention.

In the above embodiment, the fixing device 10 is composed of a framework 11 and a rod-shaped body 12, but it can also be composed of, for example, a plurality of rod-shaped bodies or a long framework. Furthermore, the fixing device 10 is not limited to being made of metal, and can be composed of a flexible fastening device such as a lashing belt. Even in this way, the present invention can shorten the length of the fastening device, so that the packaging pallet can be kept stably fixed against vibration and shaking during transportation.

In the above embodiment, the upper end (first end) 10a of the fixture 10 is fixed to the corner X inside the transport container 5, but it may also be fixed to the ceiling wall 5B or the upper part of the side walls 5C, 5D inside the transport container 5. Also, the lower end (second end) 10b of the fixture 10 is fixed to the rear lower part of the rear support part 7 or the rear part of the base part 6, but it may also be fixed to the front part of the rear support part 7 or the front part of the base part 6, or even to the upper part of the rear support part 7.

In the above embodiment, the locking member 9 is a short member that extends into the area near the corner X in the transport container 5, but it may be a long member that extends into the area of the free space S. In this case, the vertical relationship between the first end 10a and the second end 10b of the fastener 10 may be reversed.

In the above embodiment, an example has been given of the case where the lower end 10b (framework body 11) of the fixing device 10 is fixed separately to the rear support part 7 and the base part 6, but the lower end 10b of the fixing device 10 may also be fixed across both the rear support part 7 and the base part 6.

In the above embodiment, the fixing device 10 is fixed to one end of the glass sheet laminate 2 in the width direction, but it may be fixed to the other end of the width direction, or it may be fixed to both ends. In addition, the number of fixing devices 10 is not particularly limited.

In the above embodiment, the packaging pallet 3 is placed on the bottom wall 5A inside the transport container 5, but it is also possible to lay a base panel on the bottom wall 5A, for example by covering the upper surface of the panel with a rubber sheet, and then place the packaging pallet 3 on the panel.

In the above embodiment, the rear support portion 7 protrudes from one widthwise end portion 2a of the glass sheet laminate 2 (the right widthwise end portion in FIG. 4 ), and the framework body 11 of the fixing device 10 is fixed to this protruding portion 7x. However, the rear support portion 7 does not have to have a protruding portion 7x. If the rear support portion 7 does not have a protruding portion 7x, the framework body 11 of the fixing device 10 may be fixed to the end portion of the rear support portion 7 in the widthwise direction of the glass sheet laminate 2.

In the above embodiment, the transport container 5 has a ceiling wall 5B, but the transport container 5 may be an open-top container, and more specifically, may have an opening in the ceiling without having a ceiling wall 5B. In this case, the first end 10a of the fastener 10 may be fixed to the upper part of the side wall 5C, and it is preferable to fix it to the upper end of the side wall 5C.
