Abstract

PROBLEM TO BE SOLVED: To provide a pallet wherein coil-like heavy steel products can be easily fixed in a container without damaging a cargo. SOLUTION: The pallet is made of steel and includes a loading base 2m and a leg 2f. The loading base 2m comprises a loading base body 21 and a pair of cambers 24p, 24q. A form of the leg is obtained by combining legs 22a, 22b and arms 231p, 231q in a lattice. A length of the legs 22a, 22b and the arms 231p, 231q is such that a fore-and-aft length in container including a transfer gap is equally divided into four parts. Thus when four of the pallets 2 are housed in the container, there remains only such a gap that a cargo may not be unfastened and shifted, so that the pallet 2 need not be fixed to the container.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet used for transporting a heavy object such as a steel material by a transport container such as a container, a structure for attaching the pallet to the transport container, and a method of carrying in and out of the transport container. More specifically, it is used for transporting a heavy load such as a coiled steel plate by a transport container such as a container. The load is easily fixed, the load is not easily damaged, and the transfer device (particularly a floating transfer device) is used. The present invention relates to an inexpensive coiled pallet for pallets, a mounting structure for the coiled pallet for a transport container, and a method of carrying in and out of the transport container.

[0002]

2. Description of the Related Art Steel sheets (hereinafter, referred to as coils) which are handled in a coiled state are heavier (about 5 to 10 tons overseas, about 10 tons domestic) than general cargo.
Ｔ30 t), and are often moved by a large forklift or suspended from above using a large crane or the like. In the case of sea transportation, there are many methods of transporting coils by bulk load using a conventional ship.
In the case of transporting by this method, cargo handling is carried out in units of packed coils, each of which is strictly packed using rust-proof paper or iron plate to prevent scratches and rust.

[0003] However, a cargo ship handling bulk cargo is a conventional ship suitable for mass transportation, and transports a large amount of cargo at a time, so a large space for temporarily storing a large amount of transported cargo is required. Met. Further, every time the transportation method is changed, it is necessary to fix the luggage (called lashing) and the like.

[0004] Under such circumstances, container transportation of coils is desired. This is because if the luggage is stored in a container and handled, the cargo is protected by the container, which reduces damage, shortens the cargo handling time by handling the container, and reduces the interest rate of goods by shortening the transportation period. This is because the effect described above can be obtained. Although many types of containers can be selected depending on the use or the like, dry containers are the most owned, the cheapest, and easy to secure. This dry container has a high hermeticity inside the container, and if the inside of the container can be kept at a low humidity at the time of sealing, the humidity can be kept low even during the sealing. For this reason, dew condensation does not occur in the coil, and rust can be prevented from occurring.

[0005]

However, the opening of the dry container is provided on the side, and the coil cannot be stored in the dry container by a crane or the like that handles loads by hanging. Further, even in a large forklift capable of handling a heavy coil, the forklift body is larger than the opening of the dry container, and the coil cannot be stored deep inside the dry container.

In order to solve this problem, containers such as a flat container having no ceiling and an open-top container capable of opening the ceiling are prepared. Gets into the container. For this reason, unless the packing is strict, the coil will rust. Furthermore, they are often expensive compared to dry containers, and are often difficult to secure due to their small distribution volume. In addition, the opening and closing of the ceiling of an open top container was often not as easy as that of a dry container. Furthermore, even when a dry container is used, if the packaging material is made of wood or the like that easily contains moisture, the moisture in the packaging material evaporates, and the vapor condenses on the ceiling or the like, and falls on the coil. Rust is likely to occur.

[0007] In addition, a normal coil is often mounted with its axis lying sideways, so that it is easy to roll. To prevent this, the coil is fixed to a floor or a wall using a rope, wood, or the like. This required a lot of manpower and time.

[0008] The present invention is intended to solve the above-mentioned problem, and it is possible to easily transport a steel material, which is a coil-shaped heavy material, to a dry container having an opening on a side surface and to remove a flaw on a load. An object of the present invention is to provide a pallet for a coil-shaped heavy object that can easily fix a load without attaching it. Another object of the present invention is to provide a method for carrying a coiled heavy object into and out of a transport container using the coiled heavy object pallet.

[0009]

A pallet for coiled heavy objects according to a first aspect of the present invention is a pallet for coiled heavy goods which is accommodated in a transport container in a state where the coiled heavy objects are loaded. The heavy goods pallet is composed of a pallet body,
A mounting portion disposed on the pallet body and supporting the coil-shaped heavy object in contact with the cylindrical side surface of the coil-shaped heavy object; A coil opening for fixing the coiled heavy object to the pallet body, a coil fixing tool for fixing the coiled heavy object to the pallet body; Is characterized in that when it is 1, it is used alone, and when it is 2 or more, when it is combined, the size substantially matches the size of the planar shape inside the transport container.

[0010] The above-mentioned "coil-shaped heavy object" means a band-shaped object wound in a coil shape. The material of the strip is not particularly limited, and examples thereof include steel, stainless steel, aluminum, and synthetic resin. Further, the weight, width, number of turns, and the like of the coil-shaped heavy object are not particularly limited. The "transportation container" may be any one provided with a container capable of storing the coiled heavy object. Examples of the transport container include a container, a truck or a wagon equipped with a container-like container (that is, a container having a container-like container fixed on a chassis of a truck or a wagon). This is similarly applied to the following inventions.

Here, the expression “at least one side is open” does not necessarily mean that all of the directions are open, but “front”, “rear”, “right” and “left”. In other words, it only needs to be opened in one direction. That is, for example, the “lower open space” may be such that only “lower” and “rear” are open. The lower open space is a space for inserting a transport device for transporting the main pallet or a part thereof, or a space for fixing a fixing member for fixing a coiled heavy object to the main pallet, or It can be used for any other applications.

[0012] The above-mentioned "in the case of 1 alone or in the case of combining two or more in the case of 2 or more, the size substantially coincides with the plane shape inside the above-mentioned transport container" means that the bottom surface of the pallet is rectangular. When considered, the shape and size can be substantially the same as the bottom surface of the transport container. Further, the bottom shape obtained by combining two or more main pallets of various sizes and shapes can be a shape and a size that substantially match the transport container. In this pallet used in combination, for example, the shape of the pallet is determined by dividing the long side (or short side) of the bottom of the transport container into two, three, four,
It can be shaped to be equally divided into five. Similarly, the bottom surface is a pallet of 1/6, 2/6, 3/6, etc.
4) or pallets of unequal size such as 2/5, 3/5, etc. may be combined. Also, a pallet divided into six equal in size such as a bottom surface that divides the long side direction into three equal parts and the short side direction into two equal parts, that is, a pallet that is divided into two directions in the long side direction and the short side direction is combined. You may.

The above-mentioned "transport device" refers to a transport device which transports an object to be transported by placing the object to be transported on a low-floor table and moving or pushing and pulling the object. This form can be selected in various ways, for example, a floating type transport device that floats by blowing compressed air or the like downward, a sled type transport device that slides and transports, a dolly-like shape provided with wheels on the lower side. And a transporting device for hanging and transporting. Of these, a floating type transport device is preferable in that it can be operated with a small force such as hand pushing and the height of the table can be changed (regardless of whether or not it is being transported). An example of the floating type transfer device is a transfer table using an air bearing that generates an air film between itself and a floor surface.

[0014] As shown in the second aspect of the present invention, the mounting portion may be detachable from the main body of the coiled heavy object pallet. Examples of the attaching / detaching means of the mounting portion and the pallet body for a coil-shaped heavy object include, for example, screwing or using any other locking member to lock them together. Furthermore, as shown in the third invention, the mounting portion may have a slope, and a pair of the placement portions may be provided so that the slopes face each other.

Further, as described in the fourth aspect of the present invention, the coil fixing device may be a movement suppressing member provided at both ends of the coil. As this movement suppressing member, for example, a long object (a U-shaped object 26a, 26b or a rod-shaped object shown in FIG. 1) detachably attached to the movement suppressing member guide.
23 and 24, and may be upright members 28a and 28b slidably provided on a slide rail. In this slidable movement suppressing member, usually, a slide rail is provided between a pair of mounting portions at a position lower than the lower end of the slope in a direction substantially perpendicular to the direction in which the pair of mounting portions face each other. The slide rail extends from a position sandwiched between the pair of mounting portions to a range beyond the ends of the pair of mounting portions, and the slide rail includes a movement suppressing member. It may be one that is slidably opposed to each other, and the movement suppressing member may have a height reaching a position higher than the lower end of the slope. The shape of the pallet can be any shape according to the shape of the coiled heavy material to be loaded and the direction in which the coiled heavy material is loaded. For example, a leg obtained by combining four square members in a cross-girder shape In which the mounting portion is disposed, a shape in which the mounting portion is disposed on a flat base member, a box shape, or the like.

Further, as shown in the fifth invention, at least four pillar-shaped stacked support portions are arranged on the pallet body so as to form a quadrangle, and the coil-shaped heavy object is not arranged ( (If not provided), stacking of other coiled heavy goods pallets up and down may be possible. The number of the stacking supports is usually four, but may be further added to the number, and the arrangement of the four is usually a rectangle or a square, but is not limited thereto. Since the purpose is to stack other pallets up and down, the other pallets are also provided at positions corresponding to all the stacking support portions. Furthermore, the shape of the upper surface and the lower surface of the stacking support portion may be any shape as long as they are not easily shifted from each other. For example, (1) when both are flat, (2) one is a convex surface (a convex spherical surface or the like) and the other is In the case of a concave surface (such as a concave spherical surface) corresponding to this convex surface, or (3) the upper surface is provided with a locking convex portion on a flat surface, and the lower surface is provided with a corresponding locking concave portion. Can be.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 (1) Configuration of Pallet for Coiled Heavy Object A pallet 2 for a coiled heavy object according to an embodiment of the present invention will be described in detail with reference to FIGS. Will be described. The coiled heavy goods pallet 2 is generally a 20-foot dry container (inner dimensions: about 5900 to 6000 mm in length and about 2 in width).
300-2400mm, height about 2300-2400m
m) is a pallet used for storing and transporting a coiled heavy object C (see FIG. 5, hereinafter abbreviated as a coil) in a container B (see FIG. 7) referred to as m). This coil 2
Is made by winding a steel plate into a coil of about 2 tons, covering the outer peripheral surface with cardboard, vinyl sheet, etc., fitting metal rings on both column ends, and using a steel band (approximately 30 m wide) on the outer circumference.
m). If necessary, the outer peripheral surface of the coil is further covered with an iron plate.

Hereinafter, in the present embodiment, when the paired members are arranged in parallel with the axial direction of the coiled heavy object, it is assumed that they are arranged in front and back, one is p and the other is q. . In addition, when they are arranged perpendicular to the axial direction, they are arranged on the left and right, one is a and the other is b.

The pallet 2 is made of steel, and includes a mounting portion 2m and a pallet body composed of leg portions 2f, as shown in FIGS. The mounting portion 2m includes a mounting portion main body 21 and a pair of coil support portions 24p and 24q. Further, as shown in FIGS. 2 and 3, the band insertion holes 2 are provided on the right and left portions of each of the coil support portions 24p and 24q.
42a and 242b are provided. The band insertion holes 242a and 242b have different sizes on the left and right, and one of the band insertion holes 115a is longer in the left-right direction of the pallet. Further, band insertion passages 241p and 241q are provided along the back surfaces of the coil support portions 24p and 24q, and connect the left and right band insertion holes 242a and 242b.

The coil support portions 24p and 24q are provided as shown in FIG.
And a pair of steel plates disposed so as to face each other so as to form a valley and form an inclined surface, as shown in FIG. Also, as shown in FIGS. 1 and 3, the coil support portions 24p,
24q are each provided vertically on the receiver main body 21.
It is supported by a plurality of plate-like columns 245. The plate-shaped support 245 is a deformed pentagonal flat plate as shown in FIG. 3, and the bottom is fixed vertically on the mounting portion main body 21 by welding or the like, and the other three sides are connected to the coil support 24 from below. Fixed to support. In addition, since a pair of mounting portions that support the cylindrical side surface of the coil-shaped heavy object are arranged so that the slopes face each other, the coil-shaped heavy object does not roll, and the coil-shaped heavy object can be stably mounted. Can be.
In addition, since the slopes facing the cylindrical side surface of the coil-shaped heavy object are supported, it is possible to cope with coil-shaped heavy objects having various outer diameters within a certain range. Furthermore, since the inclined surface facing the cylindrical side surface of the coil-shaped heavy object is supported, even if the coil-shaped heavy object slightly swings, it is eventually pulled by gravity and settles near the center position of the pair of mounting portions. . Further, according to the present heavy pallet for coils, even in a state where the fixing work described above is omitted, the coil can be transported without causing a load shift and without scratches.

As shown in FIG. 1 and FIG. 2, the shape of the leg portion 12 is as follows: leg portions 22a, 22b and arm portions 231p, 23.
1q is a shape obtained by combining them in a grid pattern. That is, the legs 22a and 22b are arranged in parallel, and the arms 231p and 231q are arranged on the upper side so as to be perpendicular to the legs 22a and 22b. By adopting such a shape, when a plurality of pallets 2 are arranged adjacent to each other, the ends of the adjacent leg portions 22a and 22b and the arm portions 231p and 231q are in contact with each other, so that movement is limited, and The displacement can be suppressed. In addition, a lower open space 2s into which the transfer device can be inserted can be provided below and on the front and rear side surfaces of the leg 2f, so that the main pallet 2 can be easily placed on the transfer device 1. Also, the leg 22
a, 22b are about 1450 mm in length, and the arms 231p, 2
The length of 31q is about 2250 mm, and is approximately equally divided into four in the container B in the front-rear direction, including the gap for conveyance. Thus, when four main pallets 2 are stored in the container B, there is only a gap left to prevent the pallets 2 from shifting, and the pallets 2 need not be fixed to the container B.

The auxiliary legs 232a, 232 having a length of about 810 mm are provided at the lower left and right ends of the arms 231p, 231q.
2b is provided in parallel with the legs 22a and 22b. The auxiliary legs 232a and 232b are provided to stably place the main pallet 2 on the floor.

As shown in FIGS. 1 and 2, the upper side of each of the coil support portions 24p and 24q, as shown in FIGS.
The movement suppressing member guides 25p and 25q provided along the longitudinal direction of 24q are provided. The U-shaped notches 25 are provided in the movement suppressing member guides 25p and 25q.
1 is provided. The notches 251 are provided at equal intervals near both ends of the movement suppressing member guides 25p and 25q. For this reason, the interval of the paired combination at both ends can be changed stepwise between 900 and 1900 mm, and the coil having a column length corresponding to each interval can be fixed so as not to shift.

The movement suppressing members 26a, 26b used in combination with the movement suppressing member guides 25p, 25q.
Can be obtained by combining square members so as to have a U-shape provided at both ends so as to protrude downward at portions to be fitted into the notches 251. The movement restraining members 26a, 26b
Is inserted into the notch 251 of the mounting portion 2m so as to straddle the two coil support portions 24p and 24q (see FIG. 1).

(2) Method of Fixing Coiled Heavy Object to Pallet for Coiled Heavy Object Next, a method of fixing a coil on the pallet 2 for coiled heavy object will be described. First, the packed coil C
Pallet 2 using a lift or a large forklift.
Is placed on the placing section 2m. At this time, the coil C is placed so that its axis is parallel to the floor surface, and both ends of the axis are on the left and right sides of the pallet 2. Thereafter, as shown in FIG. 4, the coil 2 is placed on the mounting portion 2 m using the binding band 61 and the fixing band 62.
Fixed to. First, one end of one fixing band 62 is passed through the shaft hole of the coil C, and the fixing band 62 is inserted into the band insertion hole 11.
5b, the band is inserted into the band insertion passage 114, passes through the band insertion hole 115a, and is connected to the other end of the fixed band 62. Further, using the binding band 61, the coil C
And the pallet 2 are bundled and fixed so as to be integrated. Also,
The movement suppressing members 26a and 26b are inserted and fixed in the notches 251 on both sides of the movement suppressing member guides 25p and 25q so as to sandwich the left and right of the coil C.

The coil C mounted and fixed on the pallet 2 (see FIG. 5) is prevented from moving in the left-right direction with respect to the pallet 2 by the fixing band 62 and the movement suppressing members 26a and 26b. In addition, the coil C and the coil supporting portions 24p and 24q sandwiching the front and rear curved surfaces with the band 6
1 prevents the coil C from being detached from the pallet 2 in the front-rear direction. Also, pallet 2
For this purpose, a transfer device such as the transfer device 1 or a crane can be used. For this reason, it is possible to carry the cargo without directly contacting the coil C.

(3) Loading and Unloading Method and Storage Structure of Pallet for Coiled Heavy Material Further, the pallet 2 on which the coil C is mounted as described above is a floating type transfer device as shown in FIGS. 1 and can be transported. As shown in FIGS. 6 and 15 to 17, the transfer device 1 includes a support 11 for lifting the main pallet 2 on which the coil C is loaded, and a floor provided at a lower surface of the support 11 at a predetermined pressure. And an air bearing 12 for ejecting compressed air toward the pallet 2. When the main pallet 2 loaded with the coil C is loaded on the support 11, the compressed air is discharged to lift the support 11 from the floor. That can be done. In addition, the transfer device 1 includes a plurality of the air bearings 12 and a valve 142S provided on each of the plurality of air bearings 12 to adjust an exhaust flow rate of the air bearings 12 (FIGS. 20 to 2).
2) and a control rod 143 that can simultaneously control the opening of the plurality of valves.
By operating, fine attitude control of the support base 11 is possible.

FIG. 16 and FIG.
As shown in FIG. 2, compressed air is blown toward the ground from the nozzles (see FIGS. 18 and 19) of the balloon portion 122 provided on the four air bearings 12 provided on the lower surface side of the support base 11, and Surface. In addition, since the transfer device 1 can make the coefficient of friction with the ground extremely small by floating, even if the pallet 2 on which the coil of several t is mounted is placed on the support base 11, it can be easily transferred by hand. . As shown in FIG. 7, such a transfer device 1 is inserted into the lower open space 2s to support the pallet 2,
It can be carried in and out of the container B and the like. Thereby, the pallet 2 can be transported stably. Further, since the transport device 1 can be used, a high ceiling required for suspension is not required, and it is possible to easily carry in / out a dry container having no opening on the ceiling side.

The pallet 2 on which the coil C is mounted as described above
Is stored in the container B as shown in FIG. That is, in the depth direction of the container B, the four pallets 2 each carrying the coil C are stored so that the ends of the legs 22a and 22b are in contact with each other. Container B size of pallet 2 bottom
By standardizing the size of the bottom of the
Even if four pallets 2 are stored in any order, just container B
Can be arranged so as to match the bottom size of.
Further, even if some pallets 2 are pallets 2 'provided with loading portions 2m' for coils C 'having a different size from the coils C, no problem occurs.

By storing the pallets 2 in this manner, there is substantially no gap between the inner wall of the container B and each pallet 2, and the pallets 2 are less likely to shift during transportation of the container B. Furthermore, in the container B, the work of fixing and removing the coil C and the pallet 2 is not required only by taking the pallet 2 in and out, and the cargo can be unloaded in a short time. Further, even if the pallet 2 is shifted in the range of the transport gap, the legs 22a, 22
In addition, there is no possibility that the loads “b” are put in each other and the load is shifted.

Further, the pallet 2 does not need to be fixed to the container B with wood or the like, and since the pallet 2 itself is made of steel, it is possible to remove water-containing substances (wood and the like) from the container. It is possible to prevent condensation from occurring in the container B. Therefore, if the container B containing the pallet 2 on which the coil C is placed can be brought into a low humidity state when the container B is sealed, the inside of the container B can be kept at a low humidity during transportation without providing a dehumidifier. No rust is generated on the coil C.

Embodiment 2 (1) Configuration of Pallet for Coiled Heavy Load The pallet 2 for coiled heavy load of this embodiment has substantially the same configuration as the pallet for coiled heavy load of the first embodiment. , A movement suppressing member, a stacking support portion, and the like.

The space between the outsides of 3a and 233b is provided so as to be shorter by several cm than the width of the inner space of the container. For this reason, similarly to the auxiliary foot members 232a and 232b, it is possible to prevent the coiled heavy goods pallet 2 from moving in the left-right direction inside the container.

As shown in FIGS. 23 and 24, the front outer and rear outer corners of the side end guides 233a and 233b are tapered. That is, as shown in FIG. 24, since the width is narrow at the front and rear ends, the case where the auxiliary arm 231p is placed in the container with the auxiliary arm 231p facing forward or the case where the auxiliary arm 231q is placed in the container is It can be easily placed in a container without fine alignment. In particular, in this embodiment, since the levitation type transport device 1 is used, if the front ends of the side end guides 233a and 233b come into contact with the inner wall of the container B with a very small force, the trajectory is corrected by itself, and The pallet 2 for a coiled heavy object can be placed in a container without causing a problem. Further, a plurality of notches 231k are provided in a corner portion on the lower surface side of the bottom plate 21. This notch is for passing the bundle band 61, and the bundle band 61 does not directly hit the corners of the auxiliary arm portions 231p and 231q, so that it is hard to cut and hardly shifts in the lateral direction.

And extend outward from the facing positions to the side end guides 233a and 233b.

The slide rails 27a, 27
In b, movement suppressing members 28a and 28b are erected so as to be slidable, respectively. These movement suppressing members 28a,
The upper end of 28b is lower than or equivalent to the position of the upper ends of the camber members 24p, 24q. The upper end may be set up vertically or may be bent outward. The movement restraining members 28a and 28b have bolts that pass through the movement restraining members and are directed to the slide rails 27a and 27b. And slide rail 2
A block is accommodated in 7a, 27b, and a hole for receiving a bolt is provided in the center of the block. By turning the bolt and connecting the block to the block, the block moves upward, and the block contacts the lower surface of the upper frame of the slide rail, so that the movement suppressing members 28a and 28b can be fixed to the slide rails 27a and 27b.

The pallet 2 for a coiled heavy object according to the present embodiment.
Is provided with the movement suppressing members 28a and 28b, so that when the coil is placed with the cylindrical side surface grounded on the slopes of the camber members 24p and 24q, the coil end surface is sandwiched and fixed between the movement suppressing members 28a and 28b. be able to. Further, the movement suppressing members 28a and 28b are provided slidably on the slide rails 27a and 27b and can be fixed at predetermined positions with bolts, so that they can correspond to coils of various widths. it can. Also,
The slide rail extends from a position between the mounting portions to a range beyond an end of the mounting portion. For this reason, the pair of movement suppressing members can cope with both a coil-shaped heavy object having a width smaller than the mounting portion and a coil-shaped heavy object having a width wider than the mounting portion, and sandwich the end surface thereof. be able to.

Further, as shown in FIGS. 23 to 27, the pallet 2 for a coiled heavy object of the present embodiment has legs 22a, 2a.
The stacking support portion 29 is provided at a position above the auxiliary arm portions 231p and 231q on the upper side 2b. The stacking support portion 29 is a columnar member, and has an auxiliary arm portion 231 on the leg portions 22a and 22b.
A total of four are provided at positions sandwiching p and 231q.
The lower end of each stacking support portion 29 is provided with a lower end surface provided in a concave shape through the leg portions 22a and 22b at a position substantially coincident with the bottom surface (lower end surface) of the leg portions 22a and 22b.
The upper part is the camber member 24 by the auxiliary strut 291.
p, 24q are connected to the front and rear end faces. The lower end of the stacking support portion 29 is located at a position substantially coincident with the lower end surfaces of the legs 22a and 22b, and the height of the upper end is at a position several cm higher than the upper ends of the camber members 24p and 24q. The upper end surface is provided in a convex spherical shape, and the lower end surface is provided in a concave spherical shape.

The pallet 2 for a coiled heavy object of the present embodiment
Can be stacked by the stacking support portion 29. That is, the coil-shaped heavy goods pallet 2 placed on the floor surface
The lower end of the stacking support portion 29 of the next coiled heavy goods pallet 2 is placed on the upper end of the four stacking support portions 29. Therefore, after carrying heavy objects, a large number of empty pallets can be stacked and sent back in a compact form. Further, if the stacking support portions are adjusted to the approximate positions, the positions are automatically adjusted by the unevenness without strict alignment, and the pallets can be easily stacked. In addition, even when they are stacked, displacement is unlikely to occur. Furthermore, since the upper surface of the stacking support portion is a convex spherical surface and the lower surface is a concave spherical surface, dust and the like hardly accumulate on the upper and lower surfaces, and the stability of the pallet is not impaired.

(2) Method of fixing coil-shaped heavy object to coil-shaped heavy object pallet When fixing a coil to the coil-shaped heavy object pallet 2 of this embodiment, first, as shown in FIGS. Then, the packed coil C is placed on the slope of the camber members 24p and 24q. Then, as shown in FIGS. 29 and 30, the coil C and the coiled pallet 2 are bundled and fixed in a direction perpendicular to the axis of the coil using the bundle band 61 so that the coil C and the coiled heavy goods pallet 2 are integrated. At that time, the binding band 61
The bottom plate 21 is arranged so as to pass through a notch 231k at a corner on the lower surface side. Thereafter, the movement suppressing members 28a and 28b are moved on the slide rails 27a and 27b, and
As shown in the figure, it is arranged so as to sandwich both end faces of the coil C,
Fix the position with bolts.

In this way, as shown in FIG. 30, the coil C mounted and fixed on the coil-shaped heavy article pallet 2 is moved relative to the coil-shaped heavy article pallet 2 by the movement suppressing members 28a and 28b. Left and right movement is impeded. The coil C is formed by the coil supporting portions 24p and 24q sandwiching the front and rear curved surfaces of the coil C and the bundle band 61.
Can be prevented from being shifted in the front-rear direction with respect to the coil-shaped heavy goods pallet 2. Therefore, as shown in FIG. 31, the coil C can be lifted by the tongs or the like, and can be moved together with the coiled heavy goods pallet 2.

It should be noted that the present invention is not limited to the specific embodiments described above, but can be variously modified within the scope of the present invention depending on the purpose and application. In other words, the present coil-shaped heavy goods pallet is not limited to the shape shown in the embodiment, but may be any shape, size, and the like. In other words, the coil supporting portion of the mounting portion can be not only an inclined surface but also a coil supporting portion having a curved surface along the curved surface of the coil to be loaded. Also, the pallet body can be formed in a flat plate shape, a box shape, or the like, in addition to the cross-girder legs.

In the lower open space, not only two or more sides but also one side may be open.
At this time, when using a fixed band, a coil can be fixed by providing a groove or making a hole in a side surface serving as a wall surface and passing the band. In addition, the size of the pallet is not limited to the shape obtained by dividing the depth of the container into four as shown in the embodiment, and for example,
It can be shaped into two equal parts, three equal parts, five equal parts, etc.
When using these different sized pallets, thin coils can increase the number of containers in the container,
Even a thick coil can be loaded so as not to protrude from the pallet, and can be loaded into the container without waste using an appropriate pallet according to the size of the coil.

Further, pallets of different sizes can be combined and stored in the pallets. For example, FIG.
As shown in the figure, 1/6, 2/6 of the depth of the container
By combining pallets of (1/3) and 3/6 (1/2) size, a pallet loaded with coils can be stored without generating an extra gap in the container. Pallets having sizes of 1/5, 5/2, 2/5, etc. can be used in combination. Further, the pallet can be used not only for the 20-foot dry container shown in the embodiment, but also for a 40-foot dry container having a different size, or for an open-top container.

The weight of the coil placed on the pallet can be, for example, 100 kg or more.
It can be about 00 tons. Furthermore, 10
It is preferable to be about 0 kg to 50 ton,
Generally, it is about 1 to 20 tons. Further, the column length of the coil placed on the main pallet may be longer than the length of the coil supporting portion. That is, one end or both ends of the left and right of the coil may protrude from the coil support portion. This is because the purpose of the present pallet is sufficient if the coil can be fixed at the portion of the coil supporting portion in contact with the pallet. Also, the diameter and weight of the coil can be changed as appropriate within a range that does not hinder fixing. Further, the movement suppressing member according to the first embodiment can be formed in any shape other than the U-shape, and can be arranged in any manner. For example, as shown in FIG. 13, the movement suppressing member guide 2 is
5 can be used as a movement suppressing member.
Further, the movement suppressing member may be fixed by a method such as bolting. Further, the movement suppressing member according to the second embodiment can also have various shapes, sizes, standing heights, and the like.

When the fixed band in the band insertion path is taken out from the band insertion hole, the fixed band can be easily taken out by providing the band taking-out tool 244 as shown in FIGS. This band removal tool 2
Reference numeral 44 denotes a flat plate shape, which is inserted into and fixed to a fixing hole 243 provided in the band insertion hole 241 to be used.
The end of the band insertion path 241 can be inclined,
It is possible to prevent the fixed band 62 from passing through the band insertion path 241 to an unnecessary place.

The shape of the band insertion hole can be selected according to the band to be used.
Examples of the shape include a square shape, a circular shape, and an elliptical shape. The band insertion hole can be provided with a band removal tool for easily removing the band from the band insertion hole in the band insertion hole or the band insertion passage. The shape and size are not particularly limited as long as the band is inclined with respect to the leg portion so that the band can be easily taken out. For example, a guide may be provided by connecting the end of the insertion hole from the bottom of the insertion passage with a rod member, a plate member, or the like. Further, one of the band insertion holes can be elongated in the left-right direction of the pallet. Such a band insertion hole can also make it easy to take out the band. Further, if the band is caught around the band insertion hole due to, for example, a case where the axial length of the coil is not equal to that between the left and right band insertion holes, a load may be applied around the band insertion hole, and the band may be deformed. Such deformation can be prevented by using the above-described elongated band insertion hole. Further, in the present pallet, if the movement of the coil can be sufficiently prevented by the movement suppressing member, the coil need not be fixed by the fixing band. At this time, as shown in FIG. 11, the band insertion passage and the band insertion hole can be omitted from the pallet.

The auxiliary leg 232 provided in the first embodiment
As shown in FIGS. 11 and 12, the a and 232b need not be particularly provided that the legs can sufficiently support the entire weight. Further, by making the corners of the arm portions tapered as shown in FIG. 11, the arm portions are less likely to be caught on the wall surface of the container when carrying in and out of the container.

The stacking support used in the second embodiment may be applied to the pallet shown in the first embodiment, or the notch 231k provided in the bottom plate 21 may be provided in the bottom plate according to the first embodiment. Is also good. Further, the corners of the auxiliary arms 231p and 231q used in the first embodiment may be tapered to prevent the equipment from being damaged as in the pallet of the second embodiment.

As shown in FIG. 10, the coiled heavy goods pallet can separate the mounting portion 2m and the leg portion 2f. In such a separable pallet, a leg portion can be omitted by preparing a mounting portion provided with an appropriate coil support portion according to the size of the coil. In addition, by preparing a leg portion corresponding to the size of the container 5, it is possible to use a mounting portion having a common shape and size. The method of fixing each of the separable mounting portions and the leg portions can be arbitrarily selected, and examples thereof include screwing and the like.

The present pallet can be transported not only by a transport device but also by a conventional transport device such as a crane or a large forklift. Even in the case of using these transporting devices, the pallet can be stably transported without touching the coils on the pallet by supporting the pallet by inserting claws or the like from the lower open space. Further, the tip of the leg can be reliably supported with the adjacent object by a width wider than the width of the leg, and a movement preventing plate for preventing movement of the pallet can be provided. By providing such a wide anti-movement plate for the legs, even if the pallet shifts in the range of the transport gap, the legs of the pallet can be inserted by the anti-movement devices provided on each leg. No misalignment occurs with each other.

As a reference example, in place of the above-mentioned coiled weight, a non-coiled shape, ie, a cylindrical weight or a columnar weight made of a single molded product or the like, or a single rod-shaped weight is used. Alternatively, an aggregated weight obtained by bundling rods or the like can be used. The shape of the loading portion of the pallet used in these cases is not particularly limited as long as a heavy load to be used can be loaded.
