TECHNICAL FIELD The present invention relates to a coil transfer / conveyance device for transferring and transferring a coil of thin steel plate.

2. Description of the Related Art Conventionally, a crane has been often used to transfer a coil or transfer a coil from one transfer device to another transfer device.

However, the use of a crane has a problem in that it requires a large space and places various restrictions on other equipment. Further, since the coil is generally heavy, transporting the coil in a suspended state not only damages the inner circumference of the coil, but also poses a risk that the building must be strong. .

In addition, when transferring from one transfer device to another transfer device, a turntable may be used, but in this case, there is a problem that the direction of the coil is changed and inventory management becomes difficult. There is.

Means for Solving the Problems The present invention comprises a coil loading section, front and rear wheels, a first coil carriage traveling on a first rail, a coil loading section, front and rear wheels, A second coil carriage that travels on a second rail that is orthogonal to the first rail and that is on the same plane; and a coil stand that is installed at the intersection of the first rail and the second rail. The coil loading portion of each of the coil carriages has a V-shaped cross-section with the same orientation, and can be moved up and down, and the front and rear wheels of each coil carriage have front and rear wheel spacings equal to the rail spacings. The above-mentioned problems are solved by a coil transfer / conveyance device characterized in that two different pairs are provided.

Action The first coil carriage with the coil loaded on the coil loading section is
It travels on the first rail and is transported to the coil stand. The stopped first coil carriage lowers the coil loading unit, lowers the coil onto the coil mounting base, travels on the first rail, and separates from the mounting base.

Next, the empty second coil carriage travels on the second rail with the coil loading portion lowered, and stops at the coil mounting base. In the stopped second coil carriage, the coil loading section is raised and the coil is loaded by pushing it up. As a result, the coils are transferred from the first truck to the second truck.

The second trolley with the coil is separated from the coil stand,
Transport the coil to the designated place.

When passing through the rail break at the intersection, the coil cart can always travel on the rail intersection without being dropped because the front wheel and the rear wheel are always on the part other than the break. .

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

The coil transfer device 10 transfers and transfers a coil W of a thin steel plate, and mainly includes a shuttle type conveyor (first coil carriage) 11 and a coil carriage (second coil carriage) 12. And a coil stand 13. The shuttle type conveyor 11 has four carriages connected by a connecting rod 20.

This is to allow the collars 27a and 47a of the wheels 27 and 46 to escape when passing through this portion.

At a crossing position 50 where the first and second rails 22, 22, 41, 41 are orthogonal to each other, four supports 61 supported by the columns 60, 60 are provided.
A coil stand 13 consisting of is installed.

Next, the operation will be described.

The shuttle type conveyor 11 moves to the right as a whole and stops so that the first carriage 21 ₁ is located directly below the first coil W previously carried in the coil carry-in table 29 (see FIG. 1). State). Then, the hydraulic cylinder 24 of the first carriage 21 ₁ is operated to raise the coil loading portion 23 ₁ , and the first coil W 1
Is loaded from the bottom to the coil loading section 23 ₁ .

When the coil W is loaded on the first truck 21 ₁ , the shuttle type conveyor 11 moves the truck loading pitch toward the coil stand 13 (leftward in FIG. 1) with the coil loading section 23 ₁ raised. Move P minutes and stop. At this time, fourth carriage 21 ₄ is the head of the truck stops directly below the coil table 13. Then, the coil loading part 23 ₁ of the first truck 21 ₁ is lowered, and the coil W is lowered onto the coil receiving bases 28, 28. During this time,
The second coil W is loaded into the coil loading table 29.

The empty shuttle conveyor 11 has a coil loading unit 23 ₁
While moving down, again, the first carriage 21 ₁ is moved to the right in FIG. 1 as a whole so that the first carriage 21 ₁ is located directly below the coil carrying-in base 29. At this time, the second truck 21 ₂ which is the second truck from the tail end is located directly below the first coil W. The first, second carriage 21 _1, 21 ₂ of the coil loading section 23 _1, 23 ₂
The second coil W on the first carriage 21 ₁ and the second
The first coil W is loaded on the trolley 21 ₂ .

After that, the shuttle type conveyor 11 again operates the coil stand 13 again.
By the connecting pitch P of the dolly to lower the coil loading portions 23 ₁ and 23 ₂ of the first and second dollies 21 ₁ and 21 ₂ ,
The second coil W is lowered onto the coil cradle 28, 28. During this time, the third coil W is loaded into the coil loading table 29.

The empty shuttle conveyor 11 is again the first trolley
The whole is moved so that 21 ₁ is located directly below the coil carrying table 29, and the first coil 21 ₁ is provided with the third coil W, the second vehicle 21 ₂ is provided with the second coil W, and the third coil W is provided. The first coil W is loaded on the trolley 21 ₃ .

In this manner, the shuttle W conveys the entire shuttle-type conveyor 11 and the coil loader 23 is moved up and down between the coil loader 23 and the coil cradle 28, 28 so that the coil W can move by the pitch P of the carriage. One by one, they are carried to the coil stand 13.

Then, the shuttle conveyor 11 to a fourth truck 21 ₄ loaded with the first coil W is the fourth carriage 21 ₄ is stopped in a position directly below the coil table 13 moves toward the coil table 13 when lowers the coil loading portion 23 _4, down the first coil W to a coil stage 13.

Shuttle conveyor 11 the emptied moves towards the coil carrying base 29, fourth carriage 21 ₄ is separated from the coil table 13.

When the coil is placed on the coil stand 13, this time, the coil truck 12 moves from the standby position 51 to directly below the coil stand 13 with the coil loading section 42 lowered, and then stops. After stopping, raise the coil loading section 42 by the hydraulic cylinder 43,
The coil W on the coil stand 13 is pushed up from below and loaded on the coil loading section 42.

Then, the coil carriage 12 separates from the coil placing table 13 while keeping the coil loading section 42 raised, stops at the coil unloading table 47, lowers the coil loading section 42, and lowers the coil W to the coil unloading table 47. .

The coil carriage 12 with the coil W lowered returns to the standby position 51.
The coil W is unloaded from the coil unloading table 47 while the coil cart 12 returns to the standby position 51. The standby position may be located between the coil mounting table 13 and the coil unloading table 47.

When the coil carriage 12 returns to the standby position 51, as described above, the fourth carriage 21 ₄ is moved directly below the coil table 13 by loading the next coil W, unload the coil W to a coil stage 13. When the fourth truck 21 ₄ moves away from the coil table 13, again, a coil from a state where the coil carriage 12 is lowered to the coil loading portion 42, moves beneath the coil table 13, and loaded with the coil W Transport it to the unloading table 47 and lower it.

In this way, the coil W is transported from the coil loading table 29 to the coil mounting table 13 by the shuttle type conveyor 11,
It is transferred to the coil carrier 12 at the coil mount 13 and is transported from the coil mount 13 to the coil unloading mount 47 by the coil carrier 12.

In the above embodiment, a coil carriage may be used instead of the shuttle type conveyor 11.

Further, in FIG. 1, the coil W may be conveyed from the left end of the first rails 22 and 22 to the coil mounting table 13 by a carriage corresponding to the coil carriage 12.

According to the above-described embodiment, the coil W is transported on the rails 22 and 23 laid on the floor G and is temporarily placed on the coil stand 13 at the time of transfer. Does not need a large space. Also, there is no need to strengthen the building.

Further, since the V-shaped pads 48, 49 of the coil loading parts 23, 42 are all oriented in the same direction, the coils W can be stored in the same direction, and inventory management becomes easy.

If the coils W are stored with the same orientation, the storage space can be reduced. That is, when the coil W is viewed two-dimensionally,
In the case of a rectangular shape, if the coil W is stored without being aligned in the same direction as shown in FIG. 4, it is necessary to store the coil W in any orientation.
The space for each coil W needs to be the width of a square whose one side corresponds to the long side of the rectangle. However, like the present embodiment, if the storage is made in the same orientation (FIG. 5), the storage space can be as wide as a rectangle, so the storage space can be reduced. By the way,
Comparing the storage space when the coil W is a rectangle with side lengths of 2: 3 in plan view in FIGS. 4 and 5, FIG. 5 shows the storage space in FIG. It is clear that more coils can be stored in less space.

Further, in the above embodiment, the wheels 46 of the coil carriage 12 are
Since there are 4 on each side and 8 on each side,
As shown in the figure, cut the slit 41a of the second rail 41 into the front wheels 27 ₁ , 2
7 ₁ and rear wheels 27 ₂ , 27 ₂ always pass through one of the front wheels 27 ₁
And the rear wheels 27 ₂ are riding on the second rail 41, the running of the coil carriage 12 can smoothly in rail cuts 41a, becomes prevent damage to the rail. Especially, since the coil W is heavy, this structure is effective.

Further, each carriage 21 of the shuttle type conveyor 11 also has four wheels on one side and eight wheels on both sides, which is also for allowing the shuttle type conveyor 11 to pass through the intersection of the rails. . As described above, when simply reciprocating, as shown in FIG. 8 and FIG. 9, only the front wheels 27 ₁ and 27 _{1 of} the fourth truck 21 ₄ pass through the intersection position 50. The trolley 21 ₄ has four front wheels 27 ₁ on both sides and two rear wheels 27 ₂ on both sides, so that it is necessary to have a total of 6 wheels. Then, the other carts 21 may be provided with four conveniences. However, the interval L ₂ distance L ₁ is the front of the front wheels 27 ₁ and the rear wheel 27 of the _second rail 41, 41
Since it is narrower, 6 pieces are sufficient as described above, but conversely, when L ₁ <L ₂ , the rear wheel 27 ₂ also passes through the break 22a, so that 8 pieces are required for convenience. Therefore, the fourth trolley of the embodiment has eight wheels in order to cope with any of them and to balance the weight. Therefore, the shuttle type conveyor can smoothly pass through the intersection.

Effects of the Invention As described above, the present invention has the following effects.

Since the transfer and transfer can be performed without suspending the coil, the transfer and transfer can be performed safely and without damaging the coil. In addition, there is no need to strengthen the building,
The air in the building can be used effectively.

If the coils are always carried out in the same direction for transfer and transfer, the coils can be stored in the same direction, which facilitates inventory management and reduces the storage space.

When passing through the rail break at the intersecting position, the coil carriage can smoothly pass without falling into the break because one of the front wheels and the rear wheel is always on a portion other than the break.
