Description

[Detailed Description of the Invention] The present invention relates to a pipe packing tool for bundling a plurality of small-diameter and medium-diameter pipes.

Conventionally, the packaging method for shipping small and medium diameter pipes such as seamless pipes was simply bundling multiple pipes together.
It was held in place by several bands.

However, with this packaging method, during transshipment from a ship to a quay, or from a quay to a trailer, etc.,
It was not possible to insert the claw of a forklift between the pipes, and it was also difficult to attach wires during crane work.

Therefore, it takes time to load and unload cargo, and the time spent on board is also long, leading to an increase in transportation costs.

In addition, since the shape of the pipe bound with the band is irregular, loading is unstable.

Therefore, loading space was also wasted.

Furthermore, if the cable ties were cut during unpacking, the package would collapse all at once, which was very dangerous.

In addition, since the pipes are in contact with each other during bundling, they may scratch each other, and furthermore, water and dust tend to accumulate at the joints of the pipes during storage.

In order to solve these drawbacks of conventional packaging means, packaging tools have recently been developed in which spacers are interposed between the pipes to bundle the pipes in a regular array.

Although the cost of this spacer-type packaging tool itself is higher than that of conventional packaging tools, it provides significant benefits to overall transportation costs, such as improved loading efficiency and shortened transshipment time.

Generally, a spacer used as a packaging tool is formed with a plurality of positioning recesses for simultaneously holding a plurality of pipes.

Moreover, the materials for this spacer have conventionally been mainly made of wood or synthetic resin.

However, in the case of a spacer made of wood, the cutting operation for forming the positioning recess is complicated, and the manufacturing cost of the spacer itself is quite high.

Additionally, wood is not uniform in quality and may bend due to the weight of the pipe.

In addition, the spacer may corrode during long-term storage.
Taking these into account, wood is not suitable for the quality of the spacer.

On the other hand, synthetic resin spacers require expensive raw materials;
Furthermore, there is a drawback that the cost for molding the positioning recesses increases.

In particular, since the dimensions of the positioning recess must be set according to the pipe diameter, the number of types of molds increases, which is the biggest factor in increasing costs.

Furthermore, with spacers made of synthetic resin, disposal of waste materials at export destinations is a problem, and there is a risk of causing pollution.

The present invention solves the above-mentioned conventional problems, and provides a pipe packing tool in which the pipe positioning recess can be easily formed, the pipe has sufficient strength, and spacers can be reliably positioned with respect to each other. It is intended for that purpose.

The pipe packing tool of the present invention is characterized in that the positioning recess for the spacer that holds the pipe and the reinforcing member that assists this are molded of metal, and further includes a joining member that positions each spacer. There is.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a state in which a plurality of pipes P are packed using a pipe packing tool 1 according to the present invention.

As shown in the figure, a plurality of pipes P are regularly arranged vertically and horizontally at regular intervals and tied together.

In the example shown in FIG. 1, three locations of the pipe P are fixed by the pipe packing tool 1 according to the present invention, and furthermore, in order to stabilize the bundling state, bands are placed at the front and back of the pipe packing tool 1.
Fixed by

The pipe packing tool 1 according to the present invention includes an intermediate spacer 10 (see Figures 2A and B) interposed between vertically arranged pipes P, and end spacers 20 located at the upper and lower ends.
(See Figures 3A and 3B), and further includes a band 30 that is wound around the intermediate spacer 10 and the end spacer 20 to fix the spacers to each other.

FIG. 2A is a perspective view showing the intermediate spacer 10, and FIG. 2B is a perspective view showing the intermediate spacer 10.
The figure is an exploded perspective view showing the manufacturing state of the intermediate spacer 10.

This intermediate spacer 10 is one for holding the pipe P.
It is composed of a pair of support plates 11, a reinforcing member 12 interposed between the two support plates 11, and joining members 13 provided at both ends.

This support plate 11. The reinforcing member 12 and the joining member 13 are all formed from metal plates such as stainless steel plates and rolled steel plates.

A plurality of positioning recesses 11 a for holding the pipes P are formed in the support plate 11 .

This positioning recess 11a is formed by continuously pressing a band-shaped metal plate with a width W, and each positioning recess 11a
a is formed into a semicircular shape with a radius R.

This radius R is set according to the diameter of the pipe P to be transported.

In addition, when manufacturing the support plate 11, a large number of positioning recesses 11a are successively press-formed in advance on a long metal plate, and this metal plate is cut appropriately to accommodate the number of pipes to be packed. The number of positioning recesses 11a is set accordingly.

For example, in the example of Fig. 1, six positioning recesses 11a are required, and in the example of Fig. 2, four positioning recesses 11a are required.
The support plate 11 is manufactured by cutting a metal plate into pieces.

The reinforcing member 12 is a square pipe material or a channel material formed from a metal plate made of the same material as the support plate 11.

The joining member 13 is also formed from a metal plate of the same quality.

The joining members 13.13 on both sides have the same shape and are attached symmetrically, and the joining member 13 on the left end has an insertion claw 13a facing downward, and the joining member 13 on the right end
The insert claw 13a is formed upward.

Further, on both sides of the upper part of the left end joining member 13, a pair of guides 1 are provided for receiving the insertion claws 13a of the upper spacer.
3b is bent and formed.

Furthermore, on both sides of the lower part of the right-end joining member 13, there is a pair of guides 13 for receiving the insertion claws 13a of the lower spacer.
b is bent and formed.

A pair of band guides 13C are formed on the side surfaces of the joining member 13.

This band guide 13C is formed by lifting and bending a part of the joining member 13.

Note that the joining members 13 at both ends are attached vertically symmetrically, and the insertion claws 13a are formed upward and downward, respectively, so that they can be used interchangeably even if the intermediate spacer 10 is turned upside down by 180 degrees. This is to give it sex.

The manufacturing process of this intermediate spacer 10 is as described above, in which the support plate 11 is formed by bending a metal plate. This is done by combining the reinforcing member 12 and the joining member 13 in the state shown in FIG. 2B, and welding and joining each member.

Next, FIG. 3A is a perspective view showing the end spacer 20, and FIG. 3B is an exploded perspective view showing the manufacturing state of the end spacer 20.

This end spacer 20 consists of one support plate 11 for holding the pipe P. A reinforcing member 21 for reinforcing this support plate 11. It is composed of joining members 13 and 22 provided at both left and right ends, and an auxiliary member 23 attached to the upper side of the reinforcing member 21.

The support plate 11 is exactly the same as the support plate used for the intermediate spacer 10, and has four positioning recesses 11a formed therein.

The joining member 13 on one side is also the same as that used for the intermediate spacer 10, and the insertion claw 13a is formed downward.

Further, guides 13b are formed on both sides of the upper part, and a band guide 13C is formed slightly below the guides 13b.

On the other hand, the joining member 22 at the right end corresponds to the other joining member 13 minus the insertion claw 13a.

That is, a pair of guides 22a for receiving the insertion claws 13a of the lower intermediate spacer 10 are bent on both sides of the lower part, and a pair of band guides 22b is provided above the guides 22a. is bent and formed.

In this way, since the insertion claw 13a is provided on one of the joining members at both ends and the guide 22a is provided on the other, this end spacer 20 can be used at the top of the packaging in the orientation shown in FIG. 3A. In addition, it can be turned upside down by 180° and used as the bottom layer of packaging, making it compatible.

The reinforcing member 21 is formed of a square pipe or channel material that is slightly thicker than the reinforcing member 12 of the intermediate spacer 10.

Support plate 11. The reinforcing member 12 and the joining members 13, 22 are all made of metal plates, but the reinforcing member 23 is made of wood.

A band groove 23 a for embedding a binding band 30 is formed on the upper surface of the auxiliary member 23 .

When assembling this end spacer 20, as shown in FIG. 3B, the support plate 11. Reinforcement member 21. Joining member 13.
22 are joined to each other by welding, and the auxiliary member 23 is bonded to the reinforcing member 21 or fixed using nails, wood screws, or the like.

Next, a method of packing the pipe P using each of the spacers described above will be explained.

For packing work, first install the end spacer 20 with the wooden auxiliary member 23 facing downward, and then
The pipe P is placed on the positioning recess 11a formed in the support plate 11 of No.

Then, the intermediate spacer 10 is set from above the pipe P.

At this time, the positioning recess 1 of the support plate 11 of the intermediate spacer
1a on the upper surface of the pipe P, insert the insertion claw 13a of the joining member 13 of the intermediate spacer 10 between the guides 223 of the joining member 22 of the end spacer 20, and insert the insertion claw 13a of the joining member 13 of the end spacer 20.
is inserted between the guides 13b on the intermediate spacer 10 side.

By inserting the insertion claws 13a into each other in this way, the positioning between the upper and lower spacers is ensured.

Next, the pipes P and the intermediate spacers 10 are placed alternately, and the end spacer 20 is again set above the pipe P at the highest stage.

At this time, the end spacer 20 is placed on the upper surface of the pipe P with the support plate 11 facing downward and the positioning recess 11a placed on the upper surface of the pipe P, as shown in FIG. 3A.

Further, the insertion claws 13a on the end spacer 20 side are inserted between the guides 13b on the intermediate spacer side, and conversely, the insertion claws 13a on the intermediate spacer side are inserted between the guides 223 on the end spacer 20 side.

FIG. 4 shows how the intermediate spacers 10 interposed between the pies 14 stacked in this manner are joined.

At the left end of this figure, the state in which the insertion claw 13a and the guide 13b are joined is shown.

Then, the intermediate spacers 10 and the end spacers 20 stacked as described above are bound and fixed with a band 30.

This band 30 is embedded in the band groove 23a of the auxiliary member 23 of the end spacer 20, and is wound between the band guides 13C and 22b on the sides of each spacer 10.20.

Then, the ends of the band 30 are fixed together using a stopper 30a.

Furthermore, as shown in FIG.
to complete the packaging.

When the packaging is completed in this way, the intermediate spacer 10
Since the end spacers 20 are positioned with respect to each other by the insertion claws 13a, there is no possibility of mutual displacement.

Moreover, the band 30 has a band groove 23a and a band guide 13.
Since it is hung inside C, 22b, band 3 is attached during transportation.
No 0s are removed or cut off.

Furthermore, since there is an auxiliary member 23 made of wood on the lower surface of the lower end spacer 20, this auxiliary member 23 functions as a cushioning material and a non-slip member during loading and unloading. The positioning recess 11a of No. 11 is molded with a constant radius R according to the pipe diameter, but during this press molding, it may be difficult to set the radius R due to springback of the material.

In such a case, as shown in FIG. 6A, a flange 11b for preventing springback may be integrally formed at the end of the positioning recess 11a.

Further, as another means for preventing springback, as shown in FIG. 6B, the ribs 11C along the circumferential direction of the positioning recess 11a may be formed into a convex or concave shape.

Further, in FIG. 4, the radius R of the positioning recess 11a of the support plate 11 is made to substantially match the radius of the pipe P.

However, it is also possible to pack a pipe p having a relatively small diameter by using the support plate 11 having the radius R.

As a method, as shown in Fig. 5A, a small diameter (radius r)
) An intervening material 40 formed of resin or cardboard may be interposed between the pipe p and the four positioning parts 11a.

Furthermore, if the diameter of the pipe P is slightly smaller than the diameter of the positioning recess 11a, the pipe P may be held between two points A by the support plate 11, as shown in FIG. 5B.

7A to 7C show other embodiments of the joining member for joining the intermediate spacers and the intermediate spacer 10 and the end spacer 20.

In FIG. 7A, a guide 1 made of pipe is attached to the joining member 14 provided at the end of the intermediate spacer 10 or the end spacer 20.
4a and insert claws 14b cut out from the pins are fixed, and when joining the intermediate spacer 10 or the end spacer 20, the insert claws 14b are successively fitted into the guides 14a of the lower spacers.

In the example shown in FIG. 7B, a bent portion 15a is provided at the upper end of the joining member 15, and a guide 15b is formed by making a hole in the bent portion 15a. An insertion claw 15C consisting of a pin is provided, and the insertion claw 15C is fitted into the guide 15b of the lower spacer when assembling the spacer.

In the embodiment shown in FIGS. 7A and 7B, the pipe 14a,
Since two pins 14b, two bent portions 15a, and two pins 15C are provided, the band 30 can be wrapped between the pipes and between the pins.

Therefore, the band guide 13C as in the embodiment shown in FIG. 2 is unnecessary.

Further, in the embodiment shown in FIG. 7C, a guide 16a formed by making a hole in the upper part of the joining member 16 is inserted into the lower part of the guide 16a.
6b is provided.

When stacking the spacers one above the other, the insertion claws 16b of the upper spacers are folded into the guide holes 6a of the lower spacers, thereby joining the spacers together.

As described above, the present invention has the following effects.

(1) Since the support plate having the positioning recess is molded from a metal plate, the positioning recess can be continuously molded using an inexpensive press mold, and the manufacturing cost is low.

Further, since a large number of positioning recesses on the support plate can be continuously formed and then cut to an appropriate length for use, spacers corresponding to the number of pipes to be packed can be easily manufactured.

(2) Since the support plate is made of metal and the strength of the positioning recess is strong, it is possible to strongly hold a pipe of a smaller diameter with a positioning recess of one diameter. The number of types is smaller than the number of types of pipe diameters.

(3) Since the support plate and reinforcing members are made of metal and have sufficient strength, there is no need to worry about damage like with wooden spacers, and the shape of the spacer itself can be minimized. , packaging volume can be reduced.

(4) Since the spacer is made of metal, the spacer can be recycled as a metal resource after being unpacked in the exporting country, and there is no pollution problem when disposing of waste materials as with synthetic resins.

(5) Since a joining member is provided for joining each spacer to each other, the spacers can be accurately positioned with respect to each other, and no spacer displacement occurs during packaging work.

Therefore, the packing work can be carried out easily and the safety of the work can also be ensured.
