It is the figure which showed the connection state between a coil conveyance trolley and a rack.

Hereinafter, the rack travel type coil conveyance device according to the present invention will be described in detail with reference to the drawings.

First, the rack travel type coil transfer device 1 will be described in detail with reference to FIG.

As shown in FIG. 1, the coil conveyance device 1 includes a pair of left and right rails 11 provided on a floor surface (fixed portion) F, and a coil conveyance carriage 21 that can travel on the rails 11.

The pair of left and right rails 11 are formed in a straight line, and stoppers 12 for fixing the wheels are provided at both ends thereof.

The coil conveying carriage 21 includes a pallet part 22, a pair of left and right carriage traveling wheels 23 that are rotatably supported on the side surface of the pallet part 22, and a connecting part 24 provided at a lower end of the pallet part 22. Has been. The pallet portion 22 can be loaded with a coil C obtained by winding a rolled material (not shown) in a coil shape, and can hold the coil C so that its axis is horizontal. Further, the carriage traveling wheel 23 rolls on the rail 11, and the contact with the stopper 12 of the rail 11 prevents the deviation from the rail 11.

Furthermore, one end of the rack 31 is detachably connected to the tip of the connecting portion 24 via a connecting pin 33. The rack 31 is arranged at the center in the width direction between the rails 11 so that the tooth surface (tooth profile) faces upward. Further, a pair of left and right rack running wheels 32 are rotatably supported on the side surface of the rack 31. The rack traveling wheel 32 also rolls on the rail 11, and the contact with the stopper 12 of the rail 11 prevents the deviation from the rail 11.

A motor (pinion rotation drive means) 41 is provided on the floor surface F on the side of the rail 11. A drive shaft 43 is connected to the motor 41 via a speed reducer 42, and the drive shaft 43 is rotatably supported by a pair of left and right bearing boxes 45 disposed so as to straddle the rail 11. A pinion 44 is fitted on the drive shaft 43 between the bearing housings 45, and the pinion 44 is engaged with the rack 31. That is, the pinion 44 is disposed above the rack 31 and is engaged with the rack 31 from above.

Therefore, when the coil C loaded on the coil transport carriage 21 is transported, the motor 41 is driven and the pinion 44 is rotated. As a result, the rack 31 that meshes with the rotating pinion 44 travels on the rail 11, and therefore the coil transport carriage 21 connected to the rack 31 also travels on the rail. The loaded coil C can be transported to a predetermined place.

Here, when the coil C is repeatedly conveyed using the coil conveyance carriage 21, the carriage traveling wheel 23 and the rack traveling wheel 32 are worn. As a result, not only the coil transport carriage 21 sinks downward, but also the rack 31 sinks downward, so that the rack 31 is separated from the pinion 44 downward. As a result, there is a possibility that poor meshing occurs between the rack 31 and the pinion 44.

Therefore, in order to prevent such a meshing failure between the rack 31 and the pinion 44 due to the wear of the carriage traveling wheel 23 and the rack traveling wheel 32, the modules of the rack 31 and the pinion 44 have predetermined Is set to a value. That is, a limit wear amount that is a use limit of the cart traveling wheel 23 and the rack traveling wheel 32 is set in advance, and even when the cart traveling wheel 23 and the rack traveling wheel 32 reach the limit wear amount, The values of these modules are set so that the engagement rate between the rack 31 and the pinion 44 is always 1 or more.

Next, the case where the coil conveying apparatus 1 is applied in front of the downcoiler of the hot rolling line will be described in detail with reference to FIGS.

As shown in FIG. 2, the hot rolling line 61 constitutes a production line for hot rolled material, and on the downstream side of the hot rolling line 61 in the conveying direction of the rolled material, the rolled material is rolled. A first down coiler 62a, a second down coiler 62b, and a third down coiler 62c, which serve as rolling material winding means for winding in a coil shape, are provided in series. Moreover, the 1st coil car 63a, the 2nd coil car 63b, and the 3rd coil car 63c can be stopped in front of each downcoiler 62a, 62b, 62c, respectively. The coil cars 63a, 63b, and 63c are stopped in front of the downcoilers 62a, 62b, and 62c, so that the coils C that have been wound up by the downcoilers 62a, 62b, and 62c are delivered. 62b, 62c can run on the central axis.

And the coil conveyance apparatus 1 is provided in front of the downcoilers 62a, 62b, and 62c. At this time, the coil conveyance device 1 is arranged so that the rail 11 is parallel to the rolling material conveyance direction in the hot rolling line 61.

Therefore, when conveying the coil C, first, the rolled material rolled into the coil C by winding the rolled material rolled by the hot rolling line 61 into a coil shape by any of the downcoilers 62a, 62b, 62c. Let it form.

Next, the coil C is delivered from one of the down coilers 62a, 62b, and 62c that has been wound to the coil car 63a, 63b, and 63c that is stopped in front of the coiler.

Then, the coil cars 63a, 63b, and 63c loaded with the coil C are caused to travel on the central axis of the downcoilers 62a, 62b, and 62c toward the coil transfer device 1 and then stopped on the side of the rail 11.

Is waiting at the receiving position P1. In addition, when the second coil car 63b is loaded with the coil C, the empty coil transport carriage 21 is waiting in advance at the receiving position P2 on the rail 11 that intersects the central axis of the second downcoiler 62b. Furthermore, when the third coil car 63c is loaded with the coil C, the empty coil transport carriage 21 is waiting in advance at the receiving position P3 on the rail 11 that intersects the central axis of the third downcoiler 62c.

Next, after the coil C is delivered from one of the coil cars 63a, 63b, 63c to the coil transport carriage 21 stopped at the receiving positions P1, P2, P3, the transport carriage 21 loaded with the coil C is moved to the rail 11 It is made to drive to the delivery position P4 which becomes the downstream end.

Then, the coil C is transferred to a predetermined position from the coil transport carriage 21 stopped at the delivery position P4. Thereby, the conveyance of the coil C immediately after winding is completed.

Next, the empty coil transport carriage 21 is caused to travel to any one of the receiving positions P1, P2 and P3 and is set in a standby state.

Therefore, according to the rack traveling type coil conveyance device 1, the rack 31 is detachably connected to the coil conveyance carriage 21, and the pinion 44 fixed on the floor surface F side so as to be disposed above the rack 31. Since the meshing state between the rack 31 and the pinion 44 can be satisfactorily maintained regardless of the weight of the coil C, the coil C can be transported stably at high speed. Can do.

In addition, by fixing the pinion 44 and the motor 41, the speed reducer 42, the drive shaft 43, and the bearing box 45 for rotationally driving the pinion 44 to the floor surface F side, a set of driving devices that are these heavy objects is obtained. Since it is not necessary to mount on the coil conveyance carriage 21, the coil conveyance carriage 21 can be simplified and reduced in weight, the coil conveyance carriage 21 can be further increased in speed, and the equipment cost can be reduced. Can be achieved.

Further, by connecting the rack 31 to the coil transport carriage 21 so as to be detachable, the maintainability of the coil transport carriage 21 can be improved.

Furthermore, by setting the modules of the rack 31 and the pinion 44 on the basis of the limit wear amount of the truck running wheel 23 and the rack running wheel 32, the truck running wheel 23 and the rack running wheel 32 are worn. In addition, the meshing state between the rack 31 and the pinion 44 can be well maintained.

And by arranging the coil conveying device 1 as described above so as to face the downcoilers 62a, 62b, 62c of the hot rolling line 61, the coil C immediately after winding can be immediately conveyed. The productivity of the rolled material can be improved.
