The present invention relates to a heavy material conveying apparatus for conveying a heavy object such as, for example, a coil wound with a thin steel sheet.

Background Art Conventionally, cranes are frequently used to convey a coil or to load a coil from one conveying device to another conveying device.

However, the use of a crane has the problem of requiring a large space and placing various restrictions on other facilities.

In addition, replacing a heavy coil in a hanging state is easy to damage the coil, and also has a problem that risks are required and the building must be strengthened.

The present invention includes (1) a second load having a heavy load portion for loading and lifting a heavy load and having a first bogie running on the first rail, and a heavy load loading portion for loading and lifting a heavy load and being orthogonal to the first rail. (2) a heavy load carrying device including a second bogie running on a rail, a heavy load placing table provided at an intersection of the first rail and the second rail, and (2) a heavy load carrying section for loading and lifting heavy loads; A first bogie that runs on one rail, a second bogie that runs on a second rail orthogonal to the first rail with a heavy material loading portion for loading and lifting heavy goods, and the first bogie and the second bogie And a turntable for mounting the rails to horizontally rotate the mounting rails and selectively connecting the first rails and the second rails, and a heavy mounting bracket positioned above the mounting rails. (3) a heavy load carrying device comprising: a heavy load carrying device configured to load and lift heavy loads; a first bogie running on the first rail; and a heavy load carrying portion for loading and lifting heavy loads; A second rail traveling on the two rails and a mounting rail for alternately mounting the first and second trucks are rotated horizontally to selectively connect the first rail and the second rail by horizontally rotating the mounting rail. This object is solved by the heavy weight conveying apparatus which has a turntable and the heavy weight mounting stand formed on the said turntable above the mounting rail.

In 1 aspect of this invention, the 1st trolley | bogie which loaded the heavy goods in the heavy goods storage part runs on a 1st rail, and conveys it to a heavy goods storage stand.

The stationary first truck lowers the weight loading section, lowers the heavy load to the heavy load placing unit, and travels on the first rail to move away from the heavy loading stand.

Next, the second bogie that is emptied travels on the second rail in a state where the heavy cargo loading portion is lowered and stops at the heavy cargo loading stand.

The stationary second heavy load truck lifts the heavy load and lifts the heavy load so that the heavy load is transferred from the first bogie to the second bogie, and the second bogie that loads the heavy load is separated from the heavy load stand. It returns to a predetermined place.

In the second aspect, the heavy load is conveyed to the heavy load placing stand by the first bogie, and once lowered on the heavy placing stand by the lowering of the heavy load placing portion of the first bogie, the empty first bogie is returned from the mounting rail to the first rail. After turning on, the turntable rotates horizontally by 90 degrees to connect the mounting rail to the second rail.

Next, the second truck travels under the heavy material, and the heavy material is transferred to the second truck by the lifting of the heavy material loading part and conveyed, whereby the heavy material is conveyed in the vertical direction.

On the other hand, the turntable is rotated backward by 90 degrees, and the loading rail is connected to the first rail and is placed in a waiting state for the first bogie. As a result, the heavy load is once lowered to the fixed weight loading stand, and the first bogie moves from the first bogie to the second bogie. Since it is loaded, the direction of the heavy object is changed with respect to the travel direction of a trolley | bogie, but in this case, the direction of a heavy object does not change from the whole conveying apparatus.

In the third aspect, the heavy object is transferred from the first bogie to the second bogie and conveyed by the same action as the first aspect, but since the heavy goods placing stand rotates integrally with the turntable, the orientation of the heavy goods is changed at the time of transfer. In the meantime, the direction of the heavy object relative to the running direction of the trolley is always the same.

(Example)

Next, embodiments of the present invention will be described with reference to the drawings.

The coil conveying apparatus (heavy weight conveying apparatus) 10 conveys and transfers the coil W which wound the thin steel plate, and mainly carries out shuttle conveyor (the first trolley | bogie) 11, and the coil bogie (the second bogie) ( 12) and a coil mounting table (heavy weight mounting table) 13.

The shuttle conveyor 1l is composed of four trucks 21 connected by a connecting rod 20, and moves forward the first rails 22 and 22 by the distance of the connection pitch P of the truck 21. It is a round trip of retreat.

Each cart 21 is provided with a lifting mechanism 25 composed of a coil loading portion (heavy load portion) 23 for loading the coils W and a hydraulic cylinder 24 for lifting the coil loading portion 23 up and down. Eight wheels 27 are provided on both sides of the frame 26 of each truck 21.

On both sides of the first rails 22 and 22, the long side coil receiving bands 28 and 28 (2nd and 3rd) are formed in parallel, and the first end, which is the rearmost bogie, The coil carrying stand 29 is provided in the vicinity of the cart 21 ₁ .

The coil bogie 21 reciprocates the second rails 41 and 41 which are orthogonal to the first rails 22 and 22, and has a coil loading part for loading the coils W (heavy material loading part). ) And an elevating mechanism 44 composed of a hydraulic cylinder 43 for elevating the coil loading section 42. Eight wheels are provided on both sides of the frame 45 of the coil bogie 12. 46).

In the middle of the second rails 41 and 41, a coil carrying table 47 is provided.

The coil loading portion 23 of the shuttle conveyor 10 and the coil loading portion 42 of the coil bogie 12 are provided with pads 48 and 49 having V-shaped cross sections, and the directions thereof are all in the direction. It is in the same direction.

Cut portions 22a and 41a are formed at orthogonal portions of the first and second rails 22 and 41, and this is when the trolley 21 and the coil trolley 12 pass through this portion. In order to avoid the edges 27a and 46a of the wheels 27 and 46.

Four support bodies 61 supported by the struts 60 and 60 at the intersecting positions 50 where the first and second rails 22, 22, 41, and 41 are orthogonal to each other. The coil mounting stand I3 which consists of these is provided.

Next, the operation will be described.

The shuttle conveyor 11 moves to the right and stops as a whole so that the first trolley 21 ₁ is located immediately below the first coil W previously loaded into the coil carrying table 29 (state of FIG. 1).

Then, the hydraulic cylinder 24 of the first trolley 21 ₁ is operated to raise the coil loading section 23 ₁ , and the first coil W is pushed up from below to be loaded on the coil loading section 23 ₁ . do.

When the coil W is loaded in the first cart 21 ₁ , the shuttle conveyor 11 moves up the coil loading table 13 _{1 with the} coil loading section 23 ₁ upward (leftward in FIG. 1). ) And move as much as the connection pitch (P) of the truck.

At this time, the fourth trolley 21 _{4 that} is the first trolley stops just below the coil mounting table 13.

Next, the coil loading part 23 ₁ of the first trolley 21 ₁ is lowered, and the coil W is lowered to the coil receiving bands 28 and 28.

In the meantime, the second coil W is carried in the coil carrying table 29, and the empty shuttle type conveyor 11 has the nose loading section 21 ₁ again with the coil loading section 23 ₁ lowered. It is moved to the right as in FIG. 1 as a whole so as to be located just below the general entrainment 29, in which the second bogie 21 ₂ at the rearmost end is located just below the first coil W.

Then, the coil loading portions 23 ₁ and 23 _{2 of the} first and second bogies 21 ₁ and 21 ₂ are raised to raise the second coil W to the first bogie 21 ₁ and the second bogie 21 _2. ) The first coil (W).

Then, the shuttle conveyor 11 again moves toward the coil mounting table 13 by the connection pitch P of the truck, and the coil loading parts of the first and second trucks 21 ₁ and 21 ₂ ( 23 ₁ ) and 23 ₂ are lowered to lower the first and second coils W to the coil receiving bases 28 and 28, and the third coil W is carried in the coil loading stage 29 therebetween. .

The empty shuttle type conveyor 11, the total movement of the first truck (21 ₁₎ so as to be positioned just below the nose general enlisted 29 and the third coil on the first breaking the balance (21 ₁₎ (W) again, The second coil W is placed on the second bogie 21 ₂ and the first coil W is placed on the third bogie 21 ₃ .

In this way, the coil is transported by the reciprocating movement of the entire shuttle conveyor 11 and the coil loading portion 23 is exchanged between the coil loading portion 23 and the coil receiving bases 28 and 28 as the coil loading portion 23 moves up and down. (W) is conveyed to the coil mounting stage 13 in order of the pitch P amount of the trolley | bogie sequentially.

Thus, just below the fourth balance (21, ₄₎ the shuttle type conveyor (11) loaded with the first coil (W) in the coil mounting table 13 moves toward the fourth balance (21, ₄₎ the coil mounting table (13) When it stops in the position and stops, the coil loading part 23 ₄ is haggled and the 1st coil W is lowered to the coil mounting base 13.

The empty shuttle conveyor 11 moves toward the coil loading platform 29 and the fourth bogie 21 ₄ falls off from the coil mounting base 13.

When the coil is placed on the coil mounting base 13, this time, the coil bogie 12 moves from the standby position 51 to just below the coil mounting base 13 with the coil loading part 42 lowered. Then, the coil loading section 42 is raised by the hydraulic cylinder 43 to push up the coil W on the coil mounting table 13 from below. Load on.

Then, the coil bogie 12 moves away from the coil mounting base 13 while raising the coil mounting portion 42 and stops at the coil discharging stand 47. The coil loading portion 42 is lowered so that the coil W is lowered. Is lowered to the coil discharging stand 47, and the coil bogie 12 having the coil W lowered returns to the standby position 51.

The coil W is carried out from the coil discharging stand 47 while the coil bogie 12 is returned to the standby position 51. At this time, the standby position is formed between the coil mounting base 13 and the coil discharging stand 47. You may be in between.

When the coil bogie 12 returns to the stand-by position 51, the fourth bogie 21 ₄ loads the next coil W and moves underneath the coil mounting base 13 as described above, so that the coil W To the coil mounting table 13.

Then, when the fourth bogie 21 ₄ falls away from the coil placement stand 13, the coil bogie 12 moves directly under the coil placement stand 13 while the coil bogie 12 is lowered to form a coil ( After loading W), it is conveyed to the coil carrying table 47 and lowered.

In this way, the coil W is conveyed from the coil loading stand 29 to the coil placing stand l3 by the shuttle conveyor 11, and moved from the coil placing stand 13 to the coil bogie 12, By the coil cart l2, it is conveyed from the coil mounting base l3 to the coil carrying base 47.

Further, in the above embodiment, a coil bogie may be used instead of the shuttle conveyor 11, and in FIG. 1, the coil bogie 12 of the first rails 22, 22 is at the left end. ), The coil W may be conveyed to the coil mounting table 13.

According to the above embodiment, the coil W is conveyed onto the rails 22 and 23 attached to the floor G, and when placed, it is once placed on the coil mounting base 13, unlike the crane. It's safe, doesn't need extra space, and there's no need to solidify the building.

In addition, since the V-shaped pads 48 and 49 of the coil mounting portions 23 and 42 are all oriented in the same direction, the coil W can be aligned in the same direction and stored in stock. Becomes easy.

In addition, the storage area can be reduced by keeping the coils W in the same orientation.

That is, when the coil W is viewed in a planar shape and is rectangular, for example, as shown in FIG. 4, if the coil W is stored without being aligned in the direction of the coil W, the coil W needs to be stored in any direction. Therefore, the area per coil W needs to be square in the length of one side corresponding to the long side of the said long direction.

However, as in the present embodiment, if the storage is arranged in the same direction (FIG. 5), the storage area may be as large as a rectangle, so that the storage area can be reduced.

Incidentally, when the coil W is planar, the storage area when the side length is a rectangle of 2: 3 is compared with FIG. 4 and FIG. 5, where the coil of FIG. 5 is smaller than that of FIG. It is clear that it can.

In the above embodiment, since the wheels 46 of the coil bogie 12 have eight wheels on each side, four wheels 46, the second rail (as shown in Figs. 41) clipped area (41a) of the front wheel (46 _1, 46 ₁₎ and the rear wheel (46 _2, 46 ₂₎ as it passes through, is always the front wheel of one side (46 ₁₎ and the rear wheel (46 ₂₎ The second rail 4l is raised to smoothly travel the coil bogie 12 at the cut portion 41a of the rail and to prevent damage to the rail.

In particular, since the coil W is heavy, the present structure is effective.

In addition, each of the trolleys 21 of the shuttle conveyor 11 also has eight wheels on both sides, four on one side, but this is also to allow the shuttle conveyor 11 to exit the intersection of the rails.

As described above, only the eighth, even if only reciprocating movement is also, as shown in FIG. 9, passes through the front wheel (27 _1), (27 _1), only the intersection 50 of the 8-degree balance (21, ₄₎ Therefore, the trolley | bogie 21 'of FIG. 8 should just be equipped with six wheels in total by four front wheels 27 ₁ and two rear wheels 27 ₂ , respectively.

And the other trolley | bogie 21 should just be provided with four in total.

However, the distance L ₁ between the second rails 41 and 41 is smaller than the distance L ₂ between the front wheels 27 ₁ and the rear wheels 27 ₂ , but may be six as described above. When L ₁ > L ₂ , since the rear wheels 27 ₂ also pass through the cut portion 22a, a total of eight are required.

Therefore, since it is possible to cope with any of the fourth trolley of the embodiment, and to equip the weight balance with eight wheels, the shuttle conveyor can smoothly pass through the intersection.

Next, the coil (heavy weight) conveying apparatus 110 of another Example shown to FIG. 10 thru | or 13 conveys the coil W which wound the thin steel plate in a right angle direction, and is mainly the 1st, 2nd shuttle type | mold Conveyor (1st trolley, 2nd trolley | bogie) 111 and 112, the turntable 114, and the coil mounting stand (weight placing stand 113) are comprised.

The first shuttle conveyor 111 has a trolley l21 that travels on the first rails 112 and 122 as shown in FIG. 12. The trolley 121 is loaded with a coil W and a hydraulic cylinder.

The rotating frame 175 rotates horizontally by 90 degrees by the hydraulic cylinder 174 around the center 173.

The hydraulic cylinder l74 is attached to the support 176 so as to be horizontally rotatable, and on the lower surface of the rotating frame l75, four rollers traveling on a ring rail 177 provided on the lower frame 172 are provided. Has (178)

The coil mounting base 113 is a bogie 121 and a bogie at the bottom G of the intersection position 150 where the first, second rails 122, 122, 141, and 141 are orthogonal to each other. Each coil loading portion 123, 142 of 170 is divided into four so as to pass through is installed on the floor (G).

Each of the coil loading parts 123, 142, the coil discharging stand 147, and the coil placing table 113 have four pads 180, 181, and 182 formed so as to form a substantially V-shape. , (183) is provided, the direction is all the same.

Next, the operation will be described.

The mounting rails 171, 171 on the turntable 114 are placed in a straight line with the first rails 122, 122, and the coil loading stand 129 of the first shuttle conveyor 111 is placed. The coil W is carried in and loaded.

The coil W carried in is loaded into the coil loading part 123 of the trolley | bogie 121 which rises from the bottom, and the coil mounting stand (") is moved by the trolley | bogie 121 with the coil loading part 123 raised. 113, 113 is conveyed to the position just above, and the trolley | bogie 121 is mounted on the mounting rail 171, and the coil W is coil-mounted by the fall of the coil loading part 123. The vehicle 121 is emptied and the vehicle 121 is emptied and returned to the first rails 122 and 122.

Then, by the operation of the hydraulic cylinder 174, the turntable 114 is rotated 90 degrees horizontally from the 11th to the left, and the mounting rails 171, 171 are the second rail 141, ( 141 is in a straight line, and the trolley 170 travels directly below the coil mounts 113 and 113 in a state where the coil loading unit 142 is lowered.

At this time, the cart 170 is mounted on the mounting rails (171), (171).

Then, the coil mounting part 142 raises and pushes up from the bottom, and loads the coil W in the trolley | bogie 170. As shown in FIG.

The second cart 170 travels up to the coil discharging stand 147 and 147 and lowers the coil loading part 142 to be picked up by the coil discharging stand 147 and 147. 147 and 147 lower the coil W.

While the trolley 170 is driving the second rails 141 and 141, the turntable 114 is rotated horizontally by 90 degrees to the right, so that the mounting rails 171 and 171 become the first rail 122. ), 122 is in a line with the state, the standby state for accepting the cart 121.

Therefore, since the coils W are conveyed at right angles by the first and second shuttle conveyors 111 and 112 orthogonal to each other, the installation area of the conveying apparatus 110 can be reduced, and the conveying apparatus Since the whole of 110 is provided in the floor G, conveyance can be performed safely.

In addition, the direction of the coil W is not the same as the conveyance direction when conveyed by the 1st shuttle conveyor 111, but when conveyed by the 2nd shuttle conveyor 112, Since it is a right angle, the direction of the coil is the same at any position, which facilitates inventory management.

In addition, instead of the first shuttle conveyor 111 of the embodiment, the walking beam conveyor 211 shown in FIG. 13 may be used.

The conveyor 211 is connected to the same interval (P) by the connecting rod 220, and the first rail 222, 222 on the reciprocating movement of the forward and backward by the distance of the interval (P) It has three trolleys 221, and each trolley 221 is provided with a coil loading part (heavy material loading part) 223 which loads a coil (heavy weight) W and moves up and down by a hydraulic cylinder (not shown). have.
