Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding conveying pallet (hereinafter simply referred to as "pallet"), and more particularly,
The present invention relates to a pallet for carrying a copper rough wire wound in a coil shape.

[0002]

2. Description of the Related Art Conventionally, as a method for producing a copper rough-drawn wire, for example, copper melted in a furnace is continuously cast and rolled to continuously produce a rough-drawn wire (a wire having a diameter of about 8 mm). A manufacturing method (called SCR method) is known,
The rough drawn wire manufactured in this way is placed on a pallet in a state of being wound on a coil and continuously stacked on a pallet using a device called a coiler. is doing. Then, the wire-drawn wire placed on the pallet is pulled out and subjected to wire drawing and the like by an electric wire manufacturer or the like.

The structure of such a conventional pallet will be described with reference to FIG. This pallet consists of a pallet body 1 formed in the shape of a square plate, and a pallet body 4 on the upper surface of the pallet body 1.
It is composed of four cylindrical poles 2 which are detachably fitted into holes formed in the corners. In using this pallet, first, with the pole 2 removed from the pallet body 1, the rough wire 3 is coiled and placed on the pallet body 1 using a coiler, and the rough wire 3 is removed. Remove the pallet body 1 from the coiler at the stage when it reaches the predetermined height, attach the pole 2 to the pallet body 1,
Wrap the band all around. Here, the coiled wire 3
Usually has an outer diameter of about 1500 mm and a height of about 1000 mm, and has a total weight of 5 to 10 tons.

In the conventional pallet, since the outer circumference of the rough wire 3 which is likely to collapse in the radial direction during transportation is supported by the pole 2, there is an advantage that the collapse of the load can be prevented.

However, in the conventional pallet described above, since the mounting position of the pole 2 on the pallet body 1 is fixed, depending on the winding state of the rough wire 3, as shown in FIG. A space S may be formed between the wire 2 and the rough wire 3. In this case, in the wire drawing process performed in the next step, a part of the drawn rough drawing wire 3 falls into the space S, and even when the dropped rough drawing wire and the drawn rough drawing wire are entangled with each other, a tangle occurs. Inconvenience may occur in wire drawing. Further, when the void S is generated, a slight movement of the rough wire 3 occurs, which causes a problem that a large load collapse is likely to occur.

In order to solve these problems, for example,
It is possible to preliminarily set the standing position of the pole 2 to a position extremely close to the outer peripheral position of the rough line 3, but this cannot completely prevent the generation of the void S, and even if the outer peripheral position of the rough line 3 is temporarily reduced. If it shifts slightly outward, the hole in which the pole 2 should be fitted is blocked by the rough wire 3.
Since the mounting of the pole 2 becomes extremely difficult, the above problems cannot be solved by such means.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a pallet capable of preventing a gap from being formed between a winding and a support member such as a pole. It is an object.

[0008]

A pallet according to the present invention includes a pallet body, a plurality of support members mounted on the upper surface of the pallet body so as to be spaced apart from each other toward the center of the pallet body, and the support members. And a fixing means for fixing to the pallet body at any place.

[0009]

After the winding is placed on the pallet body, the support member is advanced toward the winding and brought into contact with the pallet body. In this state, the fixing means prevents the support member from moving, and the support member winds the winding. Can be supported.

[0010]

FIG. 1 shows the structure of a pallet according to an embodiment of the present invention.
~ It demonstrates based on FIG. In the description of the pallet of this example, the same components as those of the conventional pallet described above will be denoted by the same reference numerals and detailed description thereof will be omitted.

The pallet of this example has a pallet body 10 formed in a substantially square plate shape, on which a rough wire (winding) 3 wound in a coil is placed, and the pallet body 10
Four support members 20 attached to the upper surface of the pallet body 10 so as to be spaced apart from each other toward the center of the pallet body 10, and pins (fixing means) 40 for fixing the support member 20 to the pallet body at an arbitrary position, The four support members 20
It is composed of four connecting bands 50 that connect each other.

The upper surface of the pallet body 10 has a plurality of grooves 11 extending in a direction parallel to one side of the body 10.
However, they are formed in parallel at substantially equal intervals so that the rough wire 3 can be prevented from slipping. Further, guide grooves 12 for attaching the support member 20 to the pallet body 10 are formed at four corners of the upper surface of the pallet body 10. Each of these guide grooves 12 is the above-mentioned groove 1.
Two groove portions 13 and 1 extended in a direction orthogonal to 1
It is composed of 4. In addition, these guide grooves 12 are
Since both are configured in the same manner, refer to FIG.
The configuration of one guide groove 12 will be described, and the other guide groove 1 will be described.
A description of 2 will be omitted.

The groove portion 13 extends from the end of the pallet body 10 toward the inside thereof and is about 1/4 of the entire width of the body 10.
It is formed to extend up to the length of. The outer end (lower side in FIG. 2) of the groove 13 is closed by a closing plate 13a formed integrally with the pallet body 10. Flanges 13b protruding inward are formed on the upper portions of the two side surfaces along the longitudinal direction of the groove portion 13, respectively. The outer end of the flange 13b is slightly separated from the end of the pallet body 10 and is formed into a tapered surface. The plate 22 provided at the bottom of the support member 20 is connected to the closing plate 13a and the flange. It can be housed in a space formed between it and 13b. A large number (four in the illustrated example) of pin mounting holes 13c are formed on the bottom surface of the groove portion 13 along the length direction thereof.
Any one of them can be selected to fit the pin 40.

The groove portion 14 extends in parallel with the groove portion 13 and has a length which is about half that of the groove portion 13. Unlike the groove portion 13, the groove portion 14 has an outer end open to the outside. On the other hand, in the groove portion 14, a flange 14b is formed on the upper portion of the side surface, similarly to the groove portion 13. The outer end of the flange 14b is formed into a tapered surface and reaches the end of the pallet body 10. In addition, a large number (three in the illustrated example) of pin mounting holes 14c are formed in the bottom surface of the groove portion 14 along the length direction thereof so that the pin 40 can be fitted into any of the holes 14c. Is becoming

An insertion hole 15 for inserting a fork of a forklift is formed inside the pallet body 10 so as to penetrate in the width direction.

The four support members 20 have the same structure and are formed by bending a cylindrical pipe into a U-shape. To this support member 20, three cylindrical reinforcing rods 21 that connect the straight portions are fixed. Further, the distance between the opening ends of the support member 20 is set larger than the distance W between the grooves 13 and 14 (see FIG. 2). A disc-shaped plate 22 is fixed to the lower portion of the open end of the support member 20 by welding. The diameter of the plate 22 is made slightly smaller than the width of the inside of the grooves 13 and 14.

The pin 40 is formed with a main body inserted into the pin mounting holes 13c and 14c, and the main body is continuously formed with the main body and expanded in diameter to form the holes 13c and 1c.
4c is a normal one made up of a head that remains on the outside.

Each of the four connecting bands 50 has the same structure, and is usually composed of a belt-shaped main body made of synthetic resin or cloth and a clasp which can be tightly bound in a wound state of the main body. It has a configuration of. The connecting band 50 is tightly connected with its main body wound around the linear portions of two adjacent supporting members.

Next, a method of using the pallet of this example having the above-described structure will be described. First, in the same manner as in the prior art, the rough wire 3 is wound on the upper surface of the pallet body 10 by a coiler and placed in a coil shape. Next, the plate 22 of the support member 20 is attached to the groove portion 1 of the guide groove 12.
3 and 14 respectively. At this time, the groove 13
In, the plate 22 can be inserted into the groove 13 by inserting the plate 22 into the space between the flange 13b and the closing plate 13a. In addition, the groove 13
Since the distance W between the support members 20 and 14 is smaller than the distance between the open ends of the support member 20, as shown in FIGS. 1 and 2, one of the support members 20 (on the groove portion 13 side). The plate 22 is in a state in which it penetrates to the inside of the other plate 22. Then, the support member 20 is moved inward, and the straight portion of the support member 20 or the reinforcing rod 21 is pressed against the rough wire 3. In this state, the pin 40 is fitted into one of the pin mounting holes 13c and 14c formed in the groove portions 13 and 14 that is located closest to the plate 22 to prevent the support member 20 from moving to the outside. To do.
That is, in this state, although there is a slight play up to the pin 40, the support member 20 is practically connected to the rough wire 3.
It can be fixed in a state of being brought into contact with. This operation is performed for each support member 20.

In the pallet of this example, after the rough wire 3 is placed, the support member 20 is advanced toward the rough wire 3 and brought into contact therewith, and in this state, the movement of the support member 20 is prevented and the support member 20 is supported. Since the rough drawn line 3 can be supported by 20, there is almost no gap between the support member 20 and the rough drawn line 3. Therefore, not only is the wire draw wire 3 less likely to collapse, but also the wire draw wire is not likely to fall into the gap between the support member 20 and the wire draw wire, which prevents entanglement during wire drawing. There are advantages.

Then, the connecting band 50 is wound around the supporting member 20 attached as described above to be tightly connected, and the adjacent supporting members 20 are firmly connected to each other.

In the pallet of this example, the adjacent support members 2
Since the 0s are connected to each other, even if a radial force is applied to the rough wire 3 during, for example, transportation by truck, and this is applied to the support members 20, this force is distributed to all the support members 20. The support member 20 can be prevented from being deformed and the rough wire 3 can be prevented from collapsing.

Further, in the pallet of this example, the groove portion 13.1.
Since the support member 20 is brought into contact with the rough wire 3 by sliding in 4, the support member 20 can be easily attached and fixed to the pallet body 10 even when the rough wire 3 slightly protrudes to the outside. There is also an advantage that it can be done. Further, the pallet of this example has an advantage that it is easy to deal with the change of the coil radius of the rough wire 3 to be handled.

Further, in the pallet of this example, the distance W between the groove portions 13 and 14 is set to be smaller than the distance between the opening ends of the supporting member 20, so that, for example, the supporting member 20
Even when the support member 20 is deformed due to a large load during use, and the distance between the opening ends changes, the support member 20 can be reused without any problem. This is because by changing the inclination angle between the support member 20 and the groove 13 or 14, it is possible to absorb the change in the distance between the opening ends. Usually U like this example
In the case of using a U-shaped tube, when the distance between the open ends of the U-shaped tube changes, it cannot be reused unless it is corrected by tapping the U-shaped tube, so this advantage is practically important. is there.

Further, in the pallet of this example, since the grooves 13 and 14 are provided with the flanges 13b and 14b, respectively, even when a radial force is applied to the support member 20, the flanges 13b and 14b are supported by the support member 20. Since the support member 20 is engaged with the plate 22, there is also an advantage that it is possible to prevent the inconvenience that the support member 20 slips out from the groove and the strength is reduced.

Further, in the pallet of this example, the groove portions 13.1.
Since 4 is formed parallel to one side of the pallet body,
When a pallet is placed on a truck or the like, this side is made orthogonal to the traveling direction of the truck (that is, the groove portions 13 and 14).
(Orthogonal to the traveling direction). As a result, the pin 4 attached to the groove portions 13 and 14
There is almost no load on 0. This is because, in this case, a large load is actually applied only in the direction orthogonal to the groove portions 13 and 14. Therefore, the pin 40
As for, it is possible to use a short one having a small diameter.

Further, for example, in the structure in which the support member 20 itself is fitted and fixed to the pallet body 10, the support member 20 is used.
The lower end of the is the insertion hole 1 for inserting the fork of the forklift.
However, in the pallet of this example, the support member 20 does not project downward, and such a problem does not occur. In the palette of this example,
Even if the pin 40 abuts on the fork and floats, the pin 40 itself is hardly loaded, so that practically no inconvenience occurs.

Further, in the pallet of this example, the supporting member 2
Since 0s are attached to the four corners of the pallet body 10, there is also an advantage that the coil radius of the storable rough wire 3 with respect to the width of the pallet body 10 can be made large.

In the pallet of this example, the pin 4
4 or 3 pin mounting holes 13c and 14c for inserting 0
Although the number of holes is not limited to this, it is preferable to increase the number of the holes, for example, when handling a wire drawing coil having various diameters. Further, if the space between the holes is narrowed, the space between the support member 20 and the rough wire 3 can be further narrowed.

Further, although the supporting member 20 is composed of a U-shaped pipe in the present example, it goes without saying that it may be a linear pipe or the like.

Further, in the above-mentioned example, the wire is a rough wire, but the pallet of this example can be used for other kinds of wire.

[0032]

The pallet according to the present invention includes a pallet body, a plurality of support members mounted on the upper surface of the pallet body so as to be spaced apart from each other toward the center of the pallet body, and the support members can be installed at arbitrary places. In this state, after the winding is placed on the pallet main body, the supporting member is advanced toward the winding and brought into contact with the pallet main body. With the fixing means, the support member can be prevented from moving and the winding can be supported by the supporting member. Therefore, there is almost no gap between the supporting member and the winding. Therefore, not only is the winding wire less likely to collapse, but also the winding wire does not fall into the gap, so that it is possible to prevent tangling of the wire during the drawing operation.
