Description

Package of metal round bars

The present invention relates to a package suitable for transporting a metal round bar.

There is a long round bar shape as one form of an ingot that is a material for metal products. This is generally called a billet and is supplied to the extrusion and forging processes. Conventionally, when such a metal round bar is transported, a plurality of round bars are bundled, packed in a wooden frame, and the plurality of wooden frames are loaded in a container. The wooden frame is for preventing the round bar from being damaged, and for increasing the rigidity so that the round bar does not bend when lifted by a lift when loaded on the container.

However, according to such a conventional packing method, it takes time and labor to disassemble the wooden frame at the time of unpacking, and it also takes time and cost to dispose of the remaining wooden frame. Furthermore, the wooden frame absorbs moisture or water accumulates in the wooden frame, and the metal round bar is corroded by the moisture.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a package in a form that is easy to unpack, has little packing material, and does not corrode the round bar when transporting a metal round bar. And

In the present invention, a plurality of metal round bars are juxtaposed, and a group of parallel round bars is formed by tying ropes between adjacent round bars in the shape of a figure 8 to form a parallel round bar. A plurality of parallel round bar groups are stacked on top of the group to form a stack of round bar groups. The piled round bar group is waterproof, shock-absorbing and preventing damage. A sleeper is brought into contact with the lower surface of the stacked round bar group wrapped with the sheet, and the stacked round bar group and the sleeper are bound together by a band. Here, the stacking means that on the arranged round bars, the horizontal position is shifted by the radius and another round bar is placed, and the upper stage is substantially trapezoid or It means to pile up so that it becomes a substantial triangle. Moreover, about a sheet | seat, the some sheet | seat which has each function may be used, and the sheet | seat which has a some function together may be used.

According to the present invention, a metal round bar is stacked on a sleeper, the round bar and the sleeper are bound together, and the entire cross section is substantially trapezoidal or substantially triangular with high mechanical stability. Therefore, since the rigidity is sufficiently high, the round bar does not bend when lifted, and the load does not collapse. In addition, the rope is hung in a round shape on the parallel round bars, and the rope serves as a cushioning material to prevent contact between the round bars, so that the round bars are not damaged during loading or transportation. And since the wooden frame is not used unlike the past, unpacking work is easy and the waste remaining after unpacking can also be reduced. Moreover, since there is no wooden frame, it becomes compact, so the loading efficiency to the container is improved. Furthermore, since there is no wooden frame, moisture does not accumulate, and since the entire round bar is wrapped with a waterproof sheet, the round bar does not corrode.

It is a perspective view of the package of the present invention. It is front direction sectional drawing of a package. It is a side view of a package. It is explanatory drawing of how to hang a rope. It is front direction sectional drawing of the container which loaded the package. It is side surface sectional drawing of the container which loaded the package.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. This package is formed by binding long metal round bars, but in this embodiment, it is an aluminum round bar having a length of about 100 times the diameter. The package is constituted by As shown in FIGS. 1 to 3, the packing body 100 of the present embodiment has 30 round bars 1 stacked therein. The round bars 1 adjacent to each other in the horizontal direction are wrapped with a rope 2 in the shape of a figure 8, and the stacked round bars 1 are provided with a waterproof sheet (waterproof sheet 3) and a cushioning sheet. (Buffer sheet 4) and a sheet (breakage prevention sheet 5) having a function of preventing breakage (FIG. 3 is shown through each sheet). The sleeper 6 is brought into contact with the lower surface of the round bar 1 wrapped with each sheet, and the round bar 1 and the sleeper 6 are bound together by a band 7. Below, the structure of the package 100 is demonstrated in detail along the procedure of packing.

First, the damage prevention sheet 5, the buffer sheet 4, and the waterproof sheet 3 are spread and stacked on the pedestal on which the packing operation is performed (in order of the damage prevention sheet 5, the buffer sheet 4, and the waterproof sheet 3 from below). ). Here, the breakage preventing sheet 5 is a thick sheet made of a synthetic resin such as polyethylene. The buffer sheet 4 is a highly cushioning material made of needle felt or foamed polyethylene. Further, the waterproof sheet 3 is a thin sheet made of a synthetic resin such as polyethylene.

Next, one round bar 1 is placed on each spread sheet, and a rope 2 is hung on the round bar 1. The rope 2 is a braided polypropylene fiber, and is folded in half so that one end passes through the upper side of the round bar 1 and the other end passes through the lower side of the round bar 1 as shown in FIG. The rope 2 may be of any type, but if it is a knitted fiber, a high anti-slip effect is desirable. The rope 2 is hung on the round bar 1 in total, but the ropes 2 are not arranged at equal intervals, but one rope 2 is arranged at the center in the longitudinal direction of the round bar 1 as shown in FIG. However, five are arranged on one end side (right side) and three are arranged on the other end side (left side) so that the distance between the ropes 2 is closer on one end side. Then, the second round bar 1 is placed adjacent to the first round bar 1, and the rope 2 is hung in the shape of a figure 8 to bind the two round bars 1. That is, as shown in FIG. 4, one end side of the rope 2 (passes the upper side of the first round bar 1) is connected to the lower side of the second round bar 1 and the other end side (first round bar). 1) passes through the upper side of the second round bar 1 so that one end side and the other end side are turned upside down and crossed. Furthermore, this is repeated, and the nine round bars 1 are arranged in parallel, and finally, the ropes 2 are tied together, and the nine round bars 1 are integrated to form a first-stage parallel round bar group 11.

Next, 9 ropes 2 are arranged on the first-stage parallel round bar group 11. The position of the rope 2 is substantially the same as the rope 2 of the first-stage parallel round bar group 11, but is slightly shifted in the longitudinal direction of the round bar 1 so that the upper and lower ropes 2 contact from the longitudinal direction of the round bar 1. I have to do it. Then, one round bar 1 is placed on the rope 2 and each rope 2 is hung. Further, the second round bar 1 is arranged in parallel, and the rope 2 is hung in the shape of a figure 8. This is repeated in the same manner as in the first stage parallel round bar group 11, and the eight round bars 1 are arranged in parallel. The parallel round bar group 11 of eyes is comprised. However, the round bar 1 constituting the first-stage parallel round bar group 11 and the round bar 1 constituting the second-stage parallel round bar group 11 are displaced in the horizontal direction by the radius of the round bar 1. Thus, the round bars 1 are piled up.

Further, in the same manner, seven round bars 1 are arranged in parallel on the second-stage parallel round bar group 11 to form a third-stage parallel round bar group 11. Six round bars 1 are juxtaposed on top of each other to form a fourth round round bar group 11. As for the position of the rope 2 in each stage in the longitudinal direction of the round bar 1, the third stage is the same as the first stage, the fourth stage is the same as the second stage, and the upper and lower ropes 2 are staggered. It is arranged. In this way, a total of 30 round bars 1 are stacked in four stages, and a substantially trapezoidal stacked round bar group 12 is formed in front view. In this way, since the round bars 1 are bundled into a figure of 8 step by step, the work itself of the ropes 2 is easy, and it is easy to stack them up, and the load does not collapse.

Next, the piled round bar group 12 is wrapped with the waterproof sheet 3 and fixed with tape. Subsequently, it is wrapped with a buffer sheet 4 from above and fixed with tape. Further, it is wrapped with a damage prevention sheet 5 from above and fixed with tape.

Next, the sleepers 6 are arranged, and the piled round bar group 12 wrapped with three sheets is placed thereon. It should be noted that a sheet may be laid on the sleepers 6 arranged from the beginning, and the round bars 1 may be stacked on the sleepers. However, in this case, the sleepers 6 are hidden by the sheets and the position is not known. It is preferable to wrap the piled bar group 12 in a sheet and place it on the sleepers 6. The sleepers 6 are wooden and have a rectangular parallelepiped shape. The sleepers 6 are arranged in a direction orthogonal to the longitudinal direction of the round bar 1 and arranged in total with respect to the stacked round bar group 12, but the sleepers 6 are not arranged at equal intervals, as shown in FIG. In addition, three bars are arranged on the one end side (right side) and two on the other end side (left side) from the center in the longitudinal direction of the round bar 1 so that the distance between the sleepers 6 is closer on one end side. . Then, the stacked round bar group 12 wrapped with three sheets and each sleeper 6 are bound together by an iron band 7. A groove 61 extending in the longitudinal direction of the sleeper 6 (left and right direction in FIG. 2) is formed on the bottom surface of the sleeper 6, and when the band 7 is fitted in the groove 61, the sleeper 6 and the band 7 are round. The rod 1 is not displaced in the longitudinal direction. This sleeper 6 serves as a base for the piled-up round bar group 12 and prevents the trapezoidal shape of the piled-up round bar group 12 from collapsing when strongly tightened with the band 7. In addition, you may wrap the piled-up round bar group 12 and the sleeper 6 bound by the band 7, and in that case, the sheet of the lower part of the sleeper 6 may be grounded and broken, so that The sleepers 6 are preferably located outside the seat. Further, in the part between the rightmost sleeper 6 and the second sleeper 6 from the right and the part between the second sleeper 6 and the third sleeper 6 from the right in FIG. The stacking round bar group 12 wrapped with a sheet is bound. The band 7 and the auxiliary band 8 are the same. One package 100 is completed by the above process.

The package 100 configured in this manner has 9 round bars 1 in the first row from the bottom, 8 in the second row, 7 in the third row, and 6 round bars 1 in the fourth row. Thirty pieces are stacked in a trapezoidal shape. Each round bar 1 is bound by a rope 2 and does not contact each other. The three sheets reliably protect the round bar 1. That is, the waterproof sheet 3 prevents water from entering. Moreover, the buffer sheet 4 prevents the round bar 1 from being damaged by contact between the packing bodies 100 and contact between the packing body 100 and another object. Further, the breakage preventing sheet 5 prevents the round bar 1 from being damaged and the buffer sheet 4 from being broken. When transporting, a plurality of the packages 100 are created and loaded in the container 200.

Next, a procedure for loading the package 100 on the container 200 will be described with reference to FIGS. However, FIGS. 5 and 6 are shown through each sheet. The container 200 has a door on the front side (the side shown in FIG. 5), and carries the package 100 along the longitudinal direction of the round bar 1 from the front side. When loading, first, a packing band (not shown) is installed in the container 200. The packing band is wound from the bottom surface to the side surface of the container 200 in a direction orthogonal to the longitudinal direction of the round bar 1 (left and right direction in FIG. 5), and each end is temporarily fixed to each side surface of the container 200 with tape or the like. Subsequently, the wheel 9 and the vertical member 10 are installed in the container 200. The wheel 9 and the vertical member 10 are both made of wood, and the wheel 9 is arranged in a direction perpendicular to the longitudinal direction of the round bar 1 in a total of five with respect to the packing body 100. The position does not interfere with the sleepers 6. The wheel 9 is higher than the sleepers 6. Moreover, the vertical member 10 is provided along the both side surfaces of the container 200 according to the position of the wheel 9, and both ends of the wheel 9 are fixed to the vertical member 10, respectively. Thereby, the wheel 9 is fixed so as not to move in the container 200.

Next, the package 100 is lifted. At the time of lifting, first, two suspension bands 301 are wound on the side (one end side, the right side in FIG. 3) to which the rope 2, the sleepers 6 and the band 7 are attached at close intervals among both ends of the package 100. The suspension band 301 is made of high strength made of nylon or the like. Then, the arm 300 attached to the forklift is passed through the suspension band 301, the packaging body 100 is lifted from the longitudinal direction, and carried into the container 200 from the other end side. When the package 100 is placed on the wheel 9, the suspension band 301 is removed, and this is repeated to place the four packages 100 in parallel in the container 200.

Next, a new wheel 9 is placed on the packing body 100 in the container 200 and both ends are fixed to the vertical member 10. Then, the packing body 100 is placed on the wheel 9, and this is repeated to load a total of 16 packing bodies 100 on the container 200. Finally, all the packing bodies 100 are bundled together with a packing band. The loading of the package 100 onto the container 200 is completed through the above steps.

Since the packaging body 100 configured in this way is very rigid, the round bar 1 will not be bent and the load will not collapse when the suspension band 301 is wound around one end in the longitudinal direction and lifted. . The reason for this high rigidity is that the round bar 1 is bundled with the rope 2 into a figure of 8 one step at a time, and is further bound together with the sleepers 6 by the band 7, so that all the round bars 1 The shape of the rod 1 does not collapse, and the round bar 1 does not spread particularly at the opposite end to be lifted, and the cross-section of the piled round rod group 12 is substantially trapezoidal so that it is mechanically stable. The upper and lower round bars 1 are not displaced in the longitudinal direction due to the friction of the ropes 2 and the meshing of the ropes 2 arranged in a staggered manner, and the packing body 100 is densely attached to one end side (the lifting side) in the longitudinal direction. This is because the rope 2, the sleepers 6 and the band 7 are attached at intervals, and the auxiliary band 8 is further attached. In addition, the rope 2 is hung in the shape of a figure 8 on the parallel round bars 1 and the rope 2 serves as a cushioning material to prevent the round bars 1 from contacting each other. Not attached. Therefore, it is particularly suitable for transportation when the round bar 1 is used for forging. This is because, in forging, scratches on the surface of the material remain in the product as they are, and therefore it is usually necessary to process the surface of the material or the like. However, if the package 100 is transported, the round bar 1 will be damaged. However, such a process becomes unnecessary. Furthermore, since the parallel round bar group 11 of each stage is bundled with the rope 2, and the upper stage is a piling which has a smaller number, the rope 2 is removed in order from the upper parallel round bar group 11. If you do, you can unpack smoothly without breaking the cargo. And since the wooden frame is not used unlike the past, unpacking work is easy and the waste remaining after unpacking can also be reduced. Moreover, since there is no wooden frame, it becomes compact, and the loading efficiency to the container 200 is improved. Furthermore, since there is no wooden frame, moisture does not accumulate, and in addition, since the entire round bar 1 is wrapped with the waterproof sheet 3, the round bar 1 does not corrode.

The present invention is not limited to the above embodiment. For example, the number and attachment positions of ropes, sleepers, bands and auxiliary bands can be appropriately changed according to the diameter, material, lifting method, etc. of the round bar. As for the sheet, as described above, a sheet having a waterproof function, a sheet having a cushioning function, and a sheet having a damage prevention function may be used in an overlapping manner, or a sheet having any two functions. In addition, two sheets having the remaining one function may be used in an overlapping manner, or one sheet having three functions may be used. Furthermore, the number of round bars in one stage and the number of stages to be stacked can be changed as appropriate depending on the diameter and material of the round bars. However, if the weight of one package is about 1 ton, It is preferable from the viewpoint of transportation efficiency. Further, the upper round bar may be two or more fewer than the lower round bar. However, if the number of the upper round bars is decreased by one as described above, the round bars can be stacked and bound in the most stable form. Can be achieved and the filling rate is increased. Furthermore, the loading method on the container is an example, and can be appropriately changed according to the size and shape of the container.
