Description

[Technical field]

[0001] The present invention relates to a glass sheet transport unit, and more particularly to a glass sheet transport unit including a packaging pallet on which a glass sheet laminate is loaded, and a transport container. [Background technology]

[0002] As is well known, in the field of glass plate packaging, a glass plate laminate in which a plurality of glass plates and interleaf papers or the like are arranged alternately is loaded onto a packaging pallet. Furthermore, when transporting these glass plates, the glass plate laminate is loaded onto a packaging unit, and the resulting glass plate package is housed in a transport container.

[0003] During transportation using this transport container, it is necessary to fix the packing pallet inside the transport container. For example, Patent Document 1 discloses a method for achieving this, in which a lashing belt is hung over the top of the packing pallet and both ends of the belt are fixed to the bottom (floor) inside the transport container. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2014-122074 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, as disclosed in Patent Document 1, the method of fixing both ends of the lashing belt to the floor surface inside the transport container creates a problem of space required to fix the packing pallet, since the packing pallet is currently becoming larger in size in line with the increase in size of glass sheets.

[0006] 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 packing pallet and both ends are fixed to the floor surface of the transport container. In light of the current situation where packing pallets are also becoming larger in size due to the increase in size of glass sheets, the lashing belt must be made even longer. This makes it difficult to maintain the packing pallet in a stably fixed state against vibrations and shaking during transport.

[0007] In view of the above, an object of the present invention is 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. [Means for solving the problem]

[0008] The present invention, which has been 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 on the packing pallet is housed, and is characterized in that the unit comprises a fastener for fixing the packing pallet to an upper portion inside the transport container.

[0009] According to this configuration, even if the glass sheet package becomes larger as the glass sheet size increases, the upper part of the transport container, which has free space, can be effectively used to fix the packing pallet. This avoids the problem of space required to fix the packing pallet in the transport container. Moreover, the length of the fastener is sufficient as long as it can reach the upper part of the transport container from the packing pallet, so the packing pallet can be stably fixed against vibrations and swings during transport.

[0010] In this configuration, it is preferable that, in the transport container, the glass sheet laminate is loaded on the packaging pallet in an inclined position inclined between two side walls of the transport container.

[0011] In this way, even a large glass plate larger than the height and width dimensions of the interior space of the container can be accommodated.

[0012] In this configuration, it is preferable that a first end of the fastener 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 a ceiling wall.

[0013] In this way, a large empty space formed on the front side of the glass sheet laminate in the shipping 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 the large empty space. This improves the work efficiency when performing the fixing work.

[0014] In this configuration, it is preferable that a first end of the fastener is located on a front side of the glass sheet laminate within the transport container.

[0015] In this way, when the first end of the fastener is fixed to a corner portion inside a shipping container via a belt or the like, the stack can be prevented from coming into contact with the belt, and therefore, the glass sheets included in the stack can be prevented from being damaged due to contact with the belt.

[0016] In the above configuration, the packaging pallet may have a rear support portion that supports the glass plate laminate from the rear side, and a second end portion of the fixing device may be fixed to the rear support portion.

[0017] In this way, the second end of the fastener can be fixed by effectively utilizing the back support portion, which is a portion of the packing pallet that has high rigidity. This allows the second end of the fastener to be fixed firmly and ensures a stable fixed state.

[0018] 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.

[0019] In this way, the second end of the fastener can be fixed by effectively utilizing the base portion, which is a highly rigid portion of the packing pallet, thereby enabling the second end of the fastener to be firmly fixed and ensuring a stable fixed state.

[0020] In the above configuration, the fixing device is preferably made of metal.

[0021] In this way, the rigidity of the fastener is significantly increased compared to conventional lashing belts, etc., and loosening of the fastener during transportation is suppressed. Effect of the Invention

[0022] 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.

[0024] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A glass sheet transport unit according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0025] The glass sheet transport unit 1 according to this embodiment is obtained by adding a characteristic configuration to the glass sheet transport unit 1' shown in Fig. 1 and Fig. 2. First, the glass sheet transport unit 1' before the characteristic configuration is added will be described. Fig. 1 is a vertical sectional front view showing the glass sheet transport unit 1', and Fig. 2 is a vertical sectional side view cut along line AA in Fig. 1.

[0026] 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 accommodated. The size (vertical dimension x width dimension) of the glass sheet G is, for example, 2200 mm x 2500 mm or more, which is large. 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.

[0027] The packing pallet 3 mainly comprises a base part 6 arranged on the bottom side of the glass sheet laminate 2 to support its weight, a rear support part 7 erected on the upper part of the base part 6 to support the glass sheet laminate 2 from the rear side, and a pedestal part 8 fixed to the upper part of the rear support part 7 and on which the glass sheet laminate 2 is placed. The lower end part of the pedestal part 8 is located lower than the upper end part of the base part 6.

[0028] The base 6 has a frame 6a that is rectangular in plan view, and a plurality of reinforcing members (not shown) made of square pipes or the like that reinforce the frame 6a. The rear support 7 has a plurality of crosspiece members 7a made of square pipes or the like that are disposed below the pedestal 8 and form a framework. The pedestal 8 has an upper pedestal 8a that receives the flat portion of the glass sheet laminate 2, and a lower pedestal 8b that receives the bottom portion of the glass sheet laminate 2.

[0029] The transport container 5 has an internal space (storage section) N with a rectangular vertical front section, and this internal space N is surrounded by a bottom wall 5A, a ceiling wall 5B, two side walls 5C and 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 and 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 opposite side 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.

[0030] 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 inclined between the two side walls 5C, 5D of the transport container 5, that is, in the inclined position shown in FIG. 1. The glass sheet laminate 2 (upper base portion 8a) is in a position following 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 larger than the inclination angle of the diagonal of the internal space N of the transport container 5 with respect to the horizontal plane by 10° or less, or smaller than the inclination angle by 10° or less, and more preferably larger than the inclination angle by 5° or less, or smaller than the inclination angle by 5° or less. 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.

[0031] A locking member 9 such as a hook is attached to a corner portion X between a side wall 5C (its inner surface) located on one side of the front side of the glass sheet laminate 2 and a ceiling wall 5B (its ceiling surface). The packaging pallet 3 is placed on a bottom wall 5A (its floor surface) of a transport container 5.

[0032] [First embodiment] Fig. 3 is a longitudinal sectional front view showing a glass sheet transporting unit 1 according to a 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.

[0033] 3 and 4, the glass sheet transport unit 1 includes a fixture 10 that fixes the packing pallet 3 to the upper part inside the transport container 5. In this embodiment, the fixture 10 connects and fixes a locking member 9 attached to a corner portion X inside the transport container 5 to a back support portion 7 of the packing pallet 3. Therefore, the fixture 10 has an upper end portion 10a as a first end portion fixed to the locking member 9 at the corner portion X, and a lower end portion 10b as a second end portion fixed to the back support portion 7.

[0034] More specifically, the fixture 10 comprises a framework 11 fixed to the rear lower 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 crosspiece 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 a metal fitting, a high-strength belt, or the like.

[0035] 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 a framework body 11 of a 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.

[0036] Next, the effects of the glass sheet transport unit 1 according to the first embodiment will be described.

[0037] In this embodiment, the glass sheet package 4 is also large in size due to the large size of the glass sheet G, 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 wide free space S exists on the front side of the glass sheet laminate 2. This free space S is located in the vicinity of the mounting location of the locking member 9. Therefore, due to the presence of this free space S, the worker can connect and fix the upper end portion 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 portion 10a of the fixing device 10.

[0038] In this embodiment, since the glass sheet stack 2 is in the inclined position described above, even a large glass sheet G larger than the height and width dimensions of the internal space N of the transport container 5 can be accommodated therein.

[0039] In this embodiment, the bottom 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 bottom end 10b of the fixing device 10 is formed of a highly rigid framework body 11. Due to the synergistic effect of these factors, the bottom end of the fixing device 10 can be firmly fixed, and a stable fixed state can be ensured.

[0040] 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 make it possible to maintain the packing pallet 3 in a stably fixed state against vibrations and shaking during transportation.

[0041] [Second embodiment] FIG. 5 is a vertical sectional 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 vertical sectional side view taken along line DD in FIG.

[0042] As shown in these drawings, 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 given to the components common to both embodiments in FIG. 5 and FIG. 6, and the description thereof will be omitted.

[0043] Although the glass sheet transport unit 1 according to the embodiment of the present invention has been described above, the present invention is not limited to this, and various variations are possible without departing from the gist of the present invention.

[0044] In the above embodiment, the fixing device 10 is composed of the framework 11 and the rod-shaped body 12, but it may 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 may be composed of a flexible fastening device such as a lashing belt. Even in this way, the present invention allows the length of the fastening device to be shortened, so that the packaging pallet can be stably maintained in a fixed state against vibrations and swings during transportation.

[0045] 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 further, it may be fixed to the upper part of the rear support part 7.

[0046] In the above embodiment, the locking member 9 is a short member extending in the area near the corner portion X in the transport container 5, but it may be a long member extending in the area of ​​the empty space S. In such a case, the up-down relationship between the first end 10a and the second end 10b of the fastener 10 may be reversed.

[0047] In the above embodiment, an example has been given of the case where the lower end portion 10b (framework body 11) of the fixing device 10 is fixed separately to the rear support portion 7 and the base portion 6, but the lower end portion 10b of the fixing device 10 may also be fixed across both the rear support portion 7 and the base portion 6.

[0048] In the above embodiment, the fastener 10 is fixed to one end side in the width direction of the glass sheet laminate 2, but it may be fixed to the other end side in the width direction, or may be fixed to both ends. In addition, the number of fasteners 10 is not particularly limited.

[0049] In the above embodiment, the packing 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 packing pallet 3 on the panel.

[0050] In the above embodiment, 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. However, the rear support part 7 does not have to have the protruding part 7x. When the rear support part 7 does not have the protruding part 7x, the framework body 11 of the fixing device 10 may be fixed to the end part of the rear support part 7 in the width direction of the glass sheet laminate 2.

[0051] 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 fixture 10 may be fixed to the upper part of the side wall 5C, and is preferably fixed to the upper end of the side wall 5C. [Explanation of symbols]
