Description

  The present invention is used when a product such as a steel plate coil formed by winding a long flat steel plate into a cylindrical shape is transported in a container by a transport ship or a truck and placed in the container. Related to the palette.

  Generally, the pallet used for container transportation has a rectangular shape (or square shape) as shown by reference numeral 10 in the plan view of FIG. 8A and the front view of FIG. A penetrating forklift claw gap 11 is provided. A forklift claw is inserted into the forklift claw gap 11 from the front to the back or from the back to the front. After this insertion, the claw is raised to lift the pallet 10 so that it can be transported.

FIG. 9 shows a perspective view of a state in which a square pallet is specifically configured as a conventional pallet 10 and a steel plate coil 13 is placed on the pallet 10.
The steel plate coil 13 placed on the pallet 10 is covered with an exterior iron plate 18, and is fixed integrally to the pallet 10 with two fastening bands 15 that are hung in a cross.
As shown in the plan view in the container 20 of FIG. 10, the exterior iron plate 18 accommodates ten pallets 10-1 to 10-10 each having a steel plate coil 13 placed and fixed in the container 20. This is to prevent the steel sheet coils 13 from colliding with each other or colliding with other objects and being damaged. However, it is assumed that the container 20 has a depth of 6 m and a width of 2.34 m on the inner wall.

As shown in FIG. 10, when each pallet 10-1 to 10-10 on which the steel plate coil 13 is placed and fixed is accommodated in the container 20, the pallet 10 is transported one by one with a forklift, Pack in order from the back. In this case, for example, the pallets 10-1, 10-2, 10-3, 10-4,..., 10-9, 10-10 are accommodated in this order.
Moreover, after accommodating all the pallets 10-1 to 10-10, the steel plate coils 13 separated from each other on the pallets 10-1 to 10-10 are transported as shown in FIG. The fastening band 15 is held by the holding wood 22 so as not to be damaged by colliding with the inner wall of the container 20 or colliding with each other due to loosening, disengagement, cutting or the like of the fastening band 15 due to shaking in the middle.

  The retaining wood 22 is arranged vertically and horizontally between the steel plate coils 13 and between the steel plate coil 13 and the inner wall of the container 20 and is fixed to each other with a nail or the like. Furthermore, although each pallet 10-1 to 10-10 is arranged in two rows in the container 20 in this example, between each pallet 10-1 to 10-10 or each pallet 10-1 to 10-10, A gap is also formed between the inner wall of the container 20. When the gap is generated as described above, the pallet 10 may move due to shaking or the like, leading to damage to the steel plate coil 13 as described above. Therefore, the retaining wood 22 is fitted and fixed in the gap.

An example of this type of conventional pallet is described in Patent Document 1.
Japanese Utility Model Publication No. 51-122957

  By the way, since the conventional pallet has a rectangular shape or a square shape, when the container 20 is accommodated in, for example, two rows in the container 20 as described above, after placing one adjacent to the container 20 in the width direction, If the width of the pallet inlet required to put the other into the container was wide, there was a gap between each pallet 10-1 to 10-10 or between the inner wall of the container 20 and each pallet 10-1 to 10-10. . Therefore, in order to narrow the gap as much as possible, the pallet inlet width may be brought close to a limit dimension that allows the pallet 10 to be inserted. However, if the pallet inlet width is too narrow, the pallet 10 is difficult to be inserted.

Therefore, normally, the pallet entrance width is set to a dimension that allows the pallet 10 to be easily inserted to some extent. However, in the case of the dimensional interval, a gap generated between each pallet 10-1 to 10-10 or between the inner wall of the container 20 and each pallet 10-1 to 10-10 becomes wide. That is, there arises a problem that contradicts the ease of placing the pallet 10.
Such a defect similarly occurs not only in the container 20 but also in a space in which a volume such as a warehouse for housing the pallet 10 on which the steel plate coil 13 is placed is limited.

  The present invention has been made in view of such problems, and when arranging and storing pallets on which products are placed in a space having a limited volume such as a container or a warehouse, between pallets, An object of the present invention is to provide a pallet that can be easily accommodated so that a gap is not generated as much as possible between the inner wall forming the space and the pallet.

In order to achieve the above object, a pallet according to claim 1 of the present invention is a rectangular pallet having an insertion portion into which a pawl of a forklift is inserted below a product mounting surface. One of the two sides facing in parallel in the nail insertion direction is a trapezoid with one side being long and the other side being short.
According to this configuration, it is assumed that only one of the two sides (both sides in the insertion direction) other than the parallel opposing sides of the trapezoidal pallet is tapered. When a product is placed on this pallet and transported, and is stored in two rows in a space where the volume is limited, for example, in a container, the tapered sides of two adjacent pallets are in contact with each other. Deploy. The first pallet to be arranged first is arranged so that the short sides of the trapezoidal parallel opposing sides face the conveyance entrance side. Thereby, the entrance width of the space for arranging the second pallet formed between the tapered side of the first pallet and the inner wall of the container is larger than that in the case where the conventional rectangular pallet is arranged. Is also wide enough. This facilitates the insertion of the second pallet. In addition, since the second pallet is conveyed with the short side at the head, the substantial inlet width of the pallet becomes wider and it is easier to insert.

In addition, when the second pallet is placed next to the first pallet, the second pallet can be moved only with the force in the forward direction if the tapered sides of the second pallet come into contact with each other. Advance while abutting against the first pallet, and at the time when they are arranged next to each other, the tapered sides of each other are in contact with each other with almost no gap.
The pallet according to claim 2 of the present invention is characterized in that, in claim 1, a pallet is provided on the placement surface to restrain the movement of the product.

  According to this configuration, since the product placed on the pallet is regulated and does not move, conventionally, a fastening band for fixing the product to the pallet becomes unnecessary. In addition, when temporarily storing products in a warehouse, etc., simply placing the product on the pallet may cause it to fall off during transportation, but if the pallet is equipped with a retainer, the product is fixed. So that worry is gone.

The pallet according to claim 3 of the present invention is the pallet that handles the coil material as the product according to claim 2, wherein the retainer is fitted to at least one of an outer periphery and an inner periphery of the coil material. It is said.
According to this configuration, since the coil material placed on the pallet can be fitted and fixed, the same effect as that of the second aspect can be obtained.

As described above, according to the present invention, the rectangular pallet having the insertion portion into which the forklift claw is inserted is arranged in parallel below the product placement surface in the insertion direction of the claw into the insertion portion. One of the two sides was long and the other side was trapezoidal.
If one of the two sides other than the parallel opposing sides of the trapezoidal pallet is tapered, the product is placed on the pallet and transported, and the volume is limited. For example, a container In the case of storing in two rows, the tapered sides of two adjacent pallets are arranged so as to contact each other. The first pallet to be arranged first is arranged so that the short sides of the trapezoidal parallel opposing sides face the conveyance entrance side. Thereby, the entrance width of the space for arranging the second pallet formed between the tapered side of the first pallet and the inner wall of the space is larger than the case where the conventional rectangular pallet is arranged. Is also wide enough. This facilitates the insertion of the second pallet. In addition, since the second pallet is conveyed with the short side at the head, the substantial inlet width of the pallet becomes wider and it is easier to insert.

In addition, when the second pallet is placed next to the first pallet, the second pallet can be moved only with the force in the forward direction if the tapered sides of the second pallet come into contact with each other. Advance while abutting against the first pallet, and at the time when they are arranged next to each other, the tapered sides of each other are in contact with each other with almost no gap.
Therefore, when the pallets on which products are placed are arranged and accommodated in a space with a limited volume such as a container or a warehouse, a gap is generated as much as possible between the pallets and between the inner wall forming the space and the pallet. There is an effect that it can be easily accommodated.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Embodiment)
FIG. 1 shows a configuration of a pallet according to an embodiment of the present invention, where (a) is a plan view and (b) is a front view.
The pallet 30 shown in FIG. 1 has a trapezoidal shape in which a planar shape is tapered so that one side of a rectangular shape (or a square shape) is indicated by an arrow 30a, and a forklift claw gap 31 penetrating from the front surface to the back surface is formed. Is provided. Forklift claws 31 are inserted into the forklift claw gap 31 from the front to the back or from the back to the front. After this insertion, the claw is raised to lift the pallet 30 so that it can be transported.

  More specifically, the tapered side 30a is formed by tapering one of two sides parallel to the extension line Y1 in the direction in which the forklift claw gap 31 is inserted from the front side to the back side. Accordingly, the length a of one side of the parallel opposing side of the pallet 30 having a trapezoidal shape is longer than the length b of the other side. Here, it is assumed that a = 1.18 m and b = 1.1 m. Here, the a side is the front surface and the b side is the back surface. The taper is preferably formed at an angle of about 3 ° to 15 ° with respect to the opposing straight sides. This is because the steel plate coil 13 cannot be stably placed on the pallet 30 if the taper angle is too large.

Next, the carrying work in the case where the steel plate coil 13 described in the conventional example is placed on the pallet 30 having such a configuration and accommodated in a container will be described with reference to FIGS.
FIG. 2 is a plan view showing a state where ten pallets are accommodated in a container. FIG. 3 is a diagram for explaining points when a pallet is accommodated in a container. FIG. 4 is a plan view showing in detail a part of the state of the container in which each pallet in FIG. 2 is accommodated. FIG. 5 shows a state in which a steel plate coil is placed on each pallet shown in FIG. 4, wherein (a) is a plan view and (b) is a front view.

However, in FIG. 5, the cylindrical steel plate coil 13 is placed on the pallets 30-1 to 30-4 and is integrally fixed to the pallet 30 by the two fastening bands 15 hung on the cross. Show the state.
First, when the pallet 30 is transported into the container 20, the empty container 20 is packed and accommodated in order from the back while being transported one by one with a forklift. The pallet 30-1 is transported and accommodated. In this case, it is preferable that the pallet 30-1 is placed in contact with the corner of the inner wall of the container 20, so that the forklift claw is inserted into the forklift claw gap 31 of the pallet 30-1 from the back side and transported. The traveling direction during the transportation is opposite to the arrow Y1 shown in FIG.

Next, the next pallet 30-2 is placed next to the pallet 30-1 that has already been placed. At this time, the tapered sides 30a must come into contact with each other. Therefore, the forklift claw is inserted into the forklift claw gap 31 of the pallet 30-2 from the front and transported. The traveling direction during the transportation is the direction of the arrow Y1 shown in FIG.
In this case, as shown in FIG. 2, since the short side (1.1 m) of the trapezoidal parallel opposing sides of the already-arranged pallet 30-1 is directed to the conveyance entrance side, the pallet 30-1 The pallet entrance width, which is the distance between one end of the short side and the inner wall of the container 20, is sufficiently wider than when the conventional rectangular pallet 30 is arranged. This makes it easy to insert the next pallet 30-2 from the pallet entrance width. Further, in addition to this, the next pallet 30-2 is conveyed with the short side (1.1 m) at the head, so that the substantial pallet entrance width becomes wider and easier to put.

  Further, in the process in which the pallet 30-2 is put on the side of the pallet 30-1, if the tapered sides 30a are brought into contact with each other in the middle, the pallet 30 can be used only with the force in the forward direction. -2 advances while abutting against the already-arranged pallet 30-1, and, as shown in FIG. 4, when the two sides are arranged next to each other, the tapered sides 30a abut against each other with almost no gap. Become. In this state, a slight gap is opened between the pallet 30-2 and the inner wall of the container 20, and a wood plate or metal plate-like adjustment liner 32 is fitted into the gap.

Thereafter, similarly, the other pallets 30-3, 30-4,..., 30-9, 30-10 are conveyed and stored in this order.
Moreover, after accommodating all the pallets 30-1 to 30-10, as shown in FIG. 5, the steel plate coils 13 that are separated from each other on the pallets 30-1 to 30-10 are fastened by shaking during transportation. It is held by an iron square bar-shaped holding member 34 so that it does not collide with the inner wall of the container 20 or collide with each other due to loosening, disengagement, cutting, etc. of the band 15. The retaining member 34 may be the retaining wood 22 shown in FIG. 11 described in the conventional example.

  As described above, according to the pallet 30 of the present embodiment, when the pallets 30 on which the steel plate coils 13 are placed are stored in the container 20 in two rows, the space between the pallets 30 and the inner wall of the container 20 are stored. And the pallet 30 can be easily accommodated so that a gap is not generated as much as possible. This effect can be obtained not only in the container 20 but also in a space with a limited volume such as a warehouse. Moreover, since accommodation becomes easy, the work time concerning accommodation can be shortened by that much.

  By the way, when the conventional rectangular pallet 10 is used, there is a case where a wide gap is generated between the pallets 10 or between the inner wall of the container 20 and the pallet 10. The steel plate coil 13 was held while filling the gap. However, the retaining wood 22 is expensive and cannot be recycled because it must be treated as industrial waste by convention if the recipient is a foreign country, and after being cut in accordance with the shape of the product such as the steel plate coil 13. The work cost was high because it requires a highly skilled craftsman for this work. For these reasons, it has been expensive to transport products in the container 20 using the conventional pallet 10.

  However, if the pallet 30 is used, the gap between the pallets 30 is substantially eliminated as described above, and the gap between the pallet 30 and the inner wall of the container 20 is provided with an adjustment liner 32 that can be recycled without incurring material costs. The pallet 30 can be prevented from moving by fitting. Further, a retaining member 34 made of a recyclable metal material was used in place of the retaining wood 22. From these things, the cost for transporting a product with the container 20 can be reduced.

Next, FIG. 6 shows the configuration of the pallet 40 according to the first modification of the present embodiment, and will be described. However, FIG. 6A is a plan view and FIG. 6B is a front view, specifically showing the pallet 40 in combination with square bars or plate-like metal materials.
The pallet 40 of the first modification is configured by fixing a retainer 42 on the upper surface of the pallet 30 having the same configuration as described above. Four retainers 42 are fixed at a position where the outer periphery of the steel sheet coil 13 placed on the pallet 40 can be fitted and retained on the retainer 42 at substantially constant intervals.

  Since the steel plate coil 13 placed on the pallet 40 is held by providing the holding tool 42 in this way, the fastening band 15 described above is not necessary. Thereby, it is possible to reduce the work cost and the work time when fixing the steel sheet coil 13 with the fastening band 15. Further, when temporarily storing in a warehouse or the like, the fastening band 15 is not necessary, but if it is simply placed on a pallet, it may be displaced during transportation. However, since the steel plate coil 13 is held in the pallet 40 with the holding tool 42, there is no worry about that.

In addition, since the outer peripheral diameter of the steel plate coil 13 is not always constant, when a gap is generated when the steel plate coil 13 is placed in the four retainers 42, the above-described adjustment liner 32 is fitted to the steel plate coil. 13 does not move. Further, if each retainer 42 is moved so that it can be fixed at an arbitrary position with bolts and nuts, it is possible to cope with different outer diameters.
Next, FIG. 7 shows a configuration of a pallet 50 according to a second modification of the present embodiment, and description thereof will be given. However, (a) of FIG. 7 is a plan view and (b) is a front view, and is a view specifically showing the pallet 50 in combination with square bars or plate-like metal materials.

The pallet 50 of the second modified example is configured by fixing a retainer 52 on the upper surface of the pallet 30 having the same configuration as described above. The retainer 52 has an annular shape, and is fixed so that the inner periphery of the cylindrical hollow portion of the steel sheet coil 13 placed on the pallet 50 can be fitted and retained in the retainer 52. Yes.
By providing the retainer 52 in this way, the steel plate coil 13 placed on the pallet 50 is retained, so that the same effect as in the first modified example can be obtained.
