TECHNICAL FIELD OF THE INVENTION
The present invention relates to a technology for preventing movement of cargo loaded in containers.
[0002]
[Prior art]
Frequently, cargo is transported loaded in containers.However, if the cargo volume is smaller than the container loading volume, the cargo may collapse due to strong shaking or vibration during transportation, or if the cargo has been stored in advance. There is a possibility that the luggage may move to another position. Therefore, it is necessary to fix the cargo.
[0003]
[Problems to be solved by the invention]
[0004]
So far, wooden bars have been bridged on the side wall of the container to prevent cargo movement. In general, such a cargo movement preventing operation is performed by a worker at the site.
The wooden bar is processed to an appropriate length in accordance with the width of the container, but there is a problem that the operation cannot be completed unless an electric saw such as a chain saw is used.
In addition, some of the cargo loaded in the container is heavy. For this reason, there has been a demand for a proposal of a technique for preventing movement of container-loaded cargo which is excellent in strength and easy to work so as to be able to face such heavy objects.
[0005]
The present invention has been made in view of such circumstances, and it is possible to easily and effectively prevent undesired movement of cargo loaded in a container due to vibration and other effects generated during the movement of the container, and to have excellent strength. The purpose is to make work easier.
[0006]
[Means for Solving the Problems]
The loaded cargo movement prevention device of the present invention has a hollow cylindrical paper tube rod and a metal core inserted into the hollow of the paper tube rod.
Then, with the metal core inserted into the hollow of the paper tube rod, the paper tube rod was hooked on the side wall of the container in a bridging manner. In this way, even if the loaded cargo in the container is moved by receiving an external force during transportation, it can be prevented from moving because it is in the way. The strength is high because the metal core is contained in the paper tube rod.
The metal core is shorter than the paper tube bar, and is disposed at the center of the paper tube bar. In this case, there is no metal core at both ends of the paper tube bar. That is, since the both end portions remain hollow, the rod material has elasticity as compared with the portion of the paper tube rod material where the metal core is disposed. Therefore, even if the loaded cargo moves toward the movement prevention device of the present invention during the movement of the container, and the load is applied to the movement prevention device, the external force at that time is absorbed by the elasticity of the movement prevention device of the present invention. Is done. Therefore, it can be said that the metal core has excellent durability while maintaining the strength.
[0007]
Further, since the paper tube rod is a processed product and is not natural wood, it does not adhere to pests and eggs thereof. The paper tube rod is formed by processing used cardboard and other waste materials. Therefore, it does not violate the law on sanitary quarantine, so there is no need to adopt a pest control method or to submit a phytosanitary certificate or certificate issued by the public quarantine department.
The paper tube rod may be formed from a plurality of short paper tube rods.
The metal core is preferably a hollow rod having a channel-like cross section formed by processing a metal plate.
Further, the present invention is a method for preventing movement of cargo loaded in a container, wherein the movement preventing device is fixed to the container at a position facing the cargo, and the movement of the cargo is suppressed by the movement preventing device.
In addition, it is conceivable that the movement preventing device is arranged in a bridging manner on the opposite side wall of the container, another movement preventing device is attached to this movement preventing device as a support rod, and the other movement preventing device is fixed to the container.
As a method of attaching the movement preventing devices, a flexible metal wire (bundling wire), a fixing device such as a nail or a screw can be considered.
As another method of fixing the movement preventing device to the container, it is considered that a metal core is planted on a metal plate of an appropriate size, for example, and a paper tube rod is inserted into the metal core to be planted. Can be The metal plate may be fixed to the container, but if it is not fixed, it can be freely arranged, so that the applicable range can be expanded according to the number and size of the load.
Since the present invention utilizes a bar made of a paper tube, it can be easily processed even by a manual saw. Also, since it has a metal core, it is excellent in strength.
In addition, if another metal core is fixed to the metal core planted on the metal plate by crossing, the metal core extends vertically and horizontally (cross-shaped). In this case, since each metal core extends in all directions, it is conceivable to fit a bar made of a paper tube into each metal core.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First Embodiment)
A first embodiment of the present invention (hereinafter, “first embodiment”) will be described with reference to FIGS.
[0009]
1 to 4, reference numeral 1 indicates a container.
[0010]
The side walls 3, 3 of the container 1 are provided with a plurality of relatively wide grooves 5, 5...
[0011]
In addition, in the pair of opposing grooves 5, 5 of both side walls 3, 3 of the container 1, the load preventing device I according to this embodiment is installed in a bridging manner. The movement prevention tool I has a hollow cylindrical paper tube bar 7 and a metal core 6 inserted into the hollow 7s of the paper tube bar 7. The metal core 6 is a hollow rod-shaped body having a channel-like cross section formed by processing an appropriate metal plate. The metal core 6 is shorter than the paper tube bar 7 and is disposed at the center of the paper tube bar 7. As a result, since the metal cores 6 are not located at both ends of the paper tube bar 7, the center portion of the paper tube bar 7 is filled with the metal core 6, but both ends remain hollow. . In addition, similarly to the side wall 3 of the container 1, the strength can be increased by processing the side surface of the metal core 6 to form irregularities.
[0012]
The paper tube bar 7 is formed by reusing newspaper or cardboard, which would otherwise be a waste material. The paper tube bar 7 is somewhat longer than the width between the grooves 5 and 5 of the container 1 (the opening width of the container). Therefore, when the paper tube bar 7 is inserted between the groove portions 5 and 5, the paper tube bar 7 is press-fitted and fixed.
[0013]
Further, a plurality of (two in this embodiment) paper tube rods 7 are attached to the paper tube rod 7 as support rods extending in the vertical direction. In addition, in order to distinguish the paper tube-made bar material as a support bar from the paper tube-made bar material bridged to the container 1, the paper tube-made bar material as the support bar is indicated by a reference numeral 7A for convenience, and the support bar is used for convenience. 7A.
As a method of fixing the support rod 7A to the container 1, for example, a metal core 6 inserted into the hollow of the support rod 7A is planted on a metal plate 10 of an appropriate size by welding or other fixing means, and the planting is performed. It is conceivable to externally fit the paper tube bar 7 on the standing metal core 6.
The metal plate 10 may be fixed to the container 1, but if it is not fixed, it can move freely, so that a suitable arrangement can be made according to the number and size of the load. In this embodiment, an example in which the metal core 6 extends to the vicinity of the upper end of the support rod 7A is illustrated, but the present invention is not limited to this. It may be longer or shorter depending on the weight of the load.
The connection between the paper tube rod 7 and the support rod 7A may be a highly flexible string-like metal wire (bundling wire), nails, screws or other fixing tools. In this embodiment, a number line is used, and the number line is indicated by reference numeral 13.
[0014]
Since such a movement preventing device I is arranged to face the container loaded cargo 9, 9,..., The movement of the container loaded cargo is suppressed.
In this embodiment, the support rod 7A has a hollow cylindrical shape. However, the present invention is not limited to this. For example, a rod made of a paper tube may be halved, or an arc-shaped cross section may be used. Tubing may be used.
[0015]
FIG. 4 is an overall perspective view of the paper tube bar 7, and FIG. 5 is an exploded perspective view of the paper tube bar 7. The metal core 6 is inserted into the paper tube bar 7 in a tight fit.
[0016]
Next, the operation and effect of the first embodiment having such a configuration will be described.
[0017]
Since the paper tube bar 7 and the support rods 7A, 7A,... Are used as movement preventing means for the loaded cargo, the loaded cargo 9, 9,.
[0018]
The paper tube rod 7 and the support rods 7A, 7A,... Are processed products made of cardboard paper or the like, which is originally waste material, and are not natural wood. Therefore, no pests or their eggs are attached. Therefore, there is no risk of violating the law on sanitary quarantine, so there is no need to adopt a pest control method or to submit a plant quarantine certificate or certificate issued by the public quarantine department.
[0019]
Furthermore, both ends of the paper tube bar 7 having the metal core 6 are hollow because the metal core 6 does not exist, and therefore have elasticity as compared with the central portion of the paper tube bar. For this reason, even if the loaded cargo 9 moves toward the movement prevention tool I during the movement of the container 1 and the load is applied to the movement prevention tool I, the external force at that time is reduced by the paper tube rod. It is absorbed by the elasticity of both ends of the material 7. For this reason, it can be said that the movement preventing device I has excellent durability due to the elasticity of both ends of the paper tube rod 7 while maintaining the strength by the metal core 6 which can be said to be the skeleton. FIG. 6 shows a change state of the movement preventing device I when the movement preventing device I is added. The white arrow in FIG. 6 indicates that the loaded cargo 9 is pushing the movement prevention tool I and is slightly curved.
Further, since the paper tube rod 7 (7A) is a paper tube as the name implies, a manual saw is sufficient even without an electric saw. Therefore, the processing can be easily completed for the worker, which is very convenient. In addition, since the waste material is used, the cost can be kept low, which is environmentally and economically effective.
(Modification)
7 and 8 show a modification of the movement preventing device I. FIG.
In this modification, the paper tube bar 7 is composed of a plurality (three in this embodiment) of short paper tube members 7a, 7b, 7c. The metal core 6 is inserted loosely into the short paper tube 7a located at the center, while the metal core 6 is inserted tightly into the left and right short paper tubes 7b and 7c.
If the paper tube bar 7 can be divided, the length of the movement preventing device I can be easily adjusted. That is, by adjusting the length of the metal core 6 in accordance with the increase and decrease of the short paper tube material, the present invention can be applied to a large container and a small container.
(Second embodiment)
[0020]
Next, a second embodiment (hereinafter, “second embodiment”) will be described with reference to FIGS. 9 to 12.
[0021]
The second embodiment differs from the first embodiment in that a truncated paper tube bar 16 is inserted between the paper tube bar 7 and the container loaded cargo 9.
[0022]
The truncated paper tube bar 16 is obtained by shortening the paper tube bar 7 to an appropriate length and cutting one end of the bar tube 7 obliquely to form a truncated portion 15.
[0023]
Then, the truncated paper tube bar 16 having the truncated portion 15 is inserted into a gap 17 (see FIG. 10) formed between the bridge 7 and the container loading cargo 9, 9,. Even when the container 1 is inserted and shakes or receives vibration, the cargo loaded in the container 9 is prevented from moving due to the gap 17.
[0024]
Further, what is indicated by reference numeral 19 is a plate material interposed between the paper tube rod 7 and the container loaded cargo 9, 9,..., And a processed plate such as plywood is suitable. Since the force applied to the movement preventing device I is dispersed by entering the plate member 19, concentrated stress is less likely to be generated on the truncated paper tube bar 16 and the cargo to be loaded thereon.
[0025]
It is also possible to prevent the lower part of the plate member 19 from shifting by appropriately fixing the half-cut paper tube rod member to the container floor.
[0026]
Note that portions denoted by the same reference numerals as those in the first embodiment represent the same components as those in the first embodiment.
[0027]
In the second embodiment having such a configuration, the same operation and effect as those of the first embodiment are obtained, but the following effects are further obtained.
[0028]
Insert the truncated portion 15 of the truncated paper tube bar 16 into the gap 17 between the paper tube bar 7 bridged between the side walls 5 and 5 of the container 1 and the container loaded cargo 9, 9,. .
[0029]
By doing so, the thickness of the truncated portion 15 gradually increases from the front end to the rear end in the longitudinal direction. That is, since it has a V-shape when viewed from the side, it functions as a wedge or bluff.
[0030]
Therefore, if the truncated paper tube bar 16 is inserted into the gap 17 between the paper tube bar 7 and the container loading cargo 9, 9,. Are firmly fixed in accordance with the degree to which the truncated portion 15 is inserted.
[0031]
The truncated paper tube rod 16 may be vertically halved and then superposed and integrated into the gap 17. In this case, by increasing or decreasing the number of superimposed truncated paper tube rods 16 that are halved in accordance with the size of the gap 17, the container-loaded cargo 9, 9,, according to the size of the gap 17 is increased. Can be adjusted.
[0032]
It should be noted that the movement preventing device of the cargo loaded in the container according to the present invention is not limited to the illustrated example described above, and it is needless to say that various changes can be made without departing from the gist of the present invention.
(Third embodiment)
[0033]
Next, a third embodiment (hereinafter, “third embodiment”) will be described with reference to FIG.
[0034]
In the third embodiment, the support bar 7A is shorter than the metal core 6, and the upper end of the metal core 6 projects from the support bar 7A. Then, the metal cores 6 of the adjacent support rods 7A are bound together with one metal core 6A to a cloth by welding or a wire or other fixing means. Externally fit 7 g.
By doing so, since the support rod 7A is integrated with the single metal core 6A, the support rod 7A is excellent in strength, and can cope with heavy loaded cargo.
[0035]
【The invention's effect】
As described above, according to the present invention, a metal core is used as a paper tube bar as a movement preventing device for a loaded cargo, so that the cargo loaded in the container can move freely due to vibration or other influences generated during the movement of the container. In addition to simple and effective prevention, excellent strength and easy work.
