DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention will be described in detail with reference to FIGS.
3 to 8 show a hot-rolled coil conveying apparatus according to the present invention. In the figure, 4 is a conveyor with a saddle, 7 is a V-slat conveyor, 8 is a conveyor with a saddle, and the hot-rolled coil 3 is transferred from the conveyor with a saddle. A transfer device 9 to be mounted is an automatic communication cart provided between the divided V slat conveyors.
In a hot rolling line equipped with a hot rolling mill, the steel strip that has been hot rolled is scraped into a coil by a mandrel provided on the outlet side of the hot rolling mill. Thereafter, the hot-rolled coil is transported from the mandrel to the conveyor 4 with a saddle, which is a part of the transport device, by the hot-rolling line outlet side equipment 10 equipped with a coil lifter and the like.
[0006]
As shown in FIGS. 2a and 2b, the saddle-equipped conveyor 4 is provided with a saddle 5 on a two-conveyor chain 11, and the saddle 5 is a member inclined in the direction of travel of the conveyor chain 11 from the front and rear to the center. Therefore, the hot-rolled coil 3 is placed on the saddle 5 of the conveyor in a state in which the hole of the coil inner diameter is perpendicular to the traveling direction of the conveyor.
Such a hole side coil 6 is conveyed in the direction of the arrow of FIG. A transfer device 8 is provided at the end point of the conveyor 4 with saddle, and a V slat conveyor 7 is provided in a direction perpendicular to the conveyor 4 with saddle.
[0007]
Next, the V slat conveyor 7 will be described. The V slat conveyor 7 is provided with a rail mount 13 on the base frame 12 as shown in FIG. Two V slats 15 having rollers 14 are configured to move. The V slat 15 is configured to bend downward from the left to the center with respect to the direction in which the hot-rolled coil 3 is conveyed, and to have a gap at the center. Accordingly, the hot-rolled coil 3 on the V slat conveyor 7 is transported in a state in which the direction of the hole of the inner diameter of the coil is parallel to the traveling direction of the V slat conveyor 7. That is, according to the present invention, the saddle-equipped conveyor 4 and the V-slat conveyor 7 are provided so as to be orthogonal to each other, and not only one of the conveyor 4 with the saddle 4 and the V-slat conveyor 7 is used, but a combined apparatus configuration. Thus, the hot rolled coil 3 to be transported can be transported without changing its direction.
[0008]
As described above, the conveyor 4 with saddle conveys the hot-rolled coil 3 in a horizontal state in which the hole of the coil inner diameter is perpendicular to the traveling direction of the conveyor, and the V slat conveyor 7 transfers the hot-rolled coil 3 to the coil inner diameter. Are transported in a hole lateral state in which the direction of the holes is parallel to the traveling direction of the V slat conveyor 7. Therefore, even when the hot-rolled coil 3 to be conveyed is transferred from the saddle-equipped conveyor 4 to the V-slat conveyor 7, a direction changing device for the hot-rolled coil 3 is not required, and the conveyor structure is extremely advantageous.
[0009]
Next, the transfer device 8 for transferring the hot rolled coil 3 from the conveyor 4 with saddle to the V slat conveyor 7 will be described in detail with reference to FIG.
The transfer device 8 includes a coil transfer car 17 having a U-shaped frame 16 on the rail mount 13, and a lift car 18 that moves back and forth with respect to the traveling direction of the conveyor 4 with a saddle and that can move up and down. It is configured. Two coil transfer cars 17 are provided on the left and right sides of the conveyor 4 with saddle. The coil transfer car 17 moves forward so as to sandwich the conveyor 4 with saddle from the open portion of the U-shape, and two strips of the V slat conveyor 4 are provided. The V slat 15 can be moved backward.
[0010]
Therefore, when the hot-rolled coil 3 conveyed by the conveyor 4 with saddle comes to a position orthogonal to the V-slat conveyor 7, it is stopped by a signal from a sensor (not shown), and then the lift car 18 located below is The lift car 18 stops rising when it rises from the gap between the two conveyor chains 11 of the conveyor 4 with saddle, and the hot-rolled coil 3 is placed on the lift car 18 and rises to a predetermined height. Next, when the coil transfer car 17 having the U-shaped frame 16 moves between the pillars of the lift car 18 composed of four pillars, the lift car 18 descends and the hot rolled coil 3 is held on the coil transfer car 17. Is done. Subsequently, the coil transfer car 17 moves backward, and when it moves between the two conveyor chains 11 of the V slat conveyor 7, the coil transfer car 17 is lowered, and the hot rolled coil 3 is placed on the V slat conveyor 7, Thereafter, the coil transfer car 17 is moved forward and detached from the V slat conveyor 7.
As described above, the transfer device of the present invention does not require a transfer device that requires changing the direction of the hot-rolled coil 3, and transfers the hot-rolled coil 3 from the saddle-equipped conveyor 4 to the V-slat conveyor 7 with a simple transfer device. It is extremely advantageous.
[0011]
The above-described V slat conveyor 7 is divided into a plurality of parts. For example, when the hot-rolled coil 3 on the V-slat conveyor 7 is moved from the V-slat conveyor 7 to another place with a crane or the like, or when the hot-rolled coil 3 is placed on the V-slat conveyor 7, etc. It is necessary to stop the V slat conveyor 7. If it is a divided V slat conveyor 7, only the corresponding V slat conveyor is stopped and the hot rolled coil 3 is lifted or suspended by a crane or the like, and the other V slat conveyors 7 are stopped. There is no need to carry out normal work. On the other hand, when the V slat conveyor 7 is not divided, the entire V slat conveyor 7 is stopped every time the hot-rolled coil 3 is lifted or hung, and the workability is inferior. .
[0012]
Next, the automatic communication carriage 9 provided between the divided V slat conveyors 7 and 7 will be described in detail with reference to FIG. 6 which is an explanatory view of a part c in FIG. 3 and FIG. 8 which is an explanatory view of a conveyance form. .
As shown in FIG. 8, four sensors A, B, C, and D are arranged at the connecting portion of the V slat conveyor 7, and the upstream V slat conveyor 7 detects the presence or absence of the hot rolled coil 3. A, a sensor B for detecting the width of the hot-rolled coil 3, and a sensor C for issuing a stop command for the upstream-side V slat conveyor 7 by detecting the hot-rolled coil 3, and a downstream V-slat conveyor 7 are provided. Is provided with a sensor D for detecting whether the hot-rolled coil 3 is placed at a predetermined position of the downstream V slat conveyor 7.
Information from each of these sensors is collected in the sequencer 19, and the upstream V slat conveyor 7 is stopped by detection of the sensor C, or the transfer operation of the hot rolling coil 3 is recognized by detection of the sensor D. Then, the downstream V slat conveyor 7 is started.
[0013]
Accordingly, the automatic communication cart 9 detects the hot rolling coil 3 by the sensor C, and when the upstream V slat conveyor 7 stops, it travels to the upstream V slat conveyor 7 according to an instruction from the sequencer 19, and the hot rolling coil 3 Stop driving when positioned below. Thereafter, the automatic communication cart 9 moves up and down the lifting frame by a lifting cylinder (not shown), places the hot-rolled coil 3 on the automatic communication cart 9, stops rising, and moves toward the V slat conveyor 7 on the downstream side. Run. After traveling to the V slat conveyor 7 on the downstream side, the elevating frame is lowered, and the automatic communication carriage 9 moves backward from the V slat conveyor 7. A series of such movements are detected by the sensors A, B, C, and D, sent to the sequencer 19, and continuously performed according to operation instructions from the sequencer 19.
