Hereinafter, the operation of the reel device 30 will be sequentially described with reference to Table 1 below, with the state shown in FIG. 1 being the initial state.

(Period A)

In period A, in the state shown in FIG. 1, the sheet-like to-be-rolled material 3 by which the 1st mandrel 31a was rolled is wound up in coil shape. That is, in the state where the power source of the 1st mandrel 31a is the main electric motor 35, the 1st mandrel 31a is winding the to-be-rolled material 3 at the winding speed of 1200mpm. This is the state in which the 1st clutch device 45a shown in FIG. 2 was connected with the 1st main clutch gear 43a. In other words, the connection state between the main drive shaft 35b and the first rotation shaft 31b is in the transmission state, and the connection state between the first auxiliary drive shaft 36b and the first rotation shaft 31b is in the non-transmission state.

On the other hand, the 2nd mandrel 32a shown in FIG. 1 is stationary and waiting. At this time, the 2nd clutch device 45b shown in FIG. 2 is in the state connected with the 2nd auxiliary clutch gear 44b. That is, in this state, the 2nd clutch device 45b is located inside the position of the 2nd clutch device 45b shown in FIG. In other words, the connection state between the main drive shaft 35b and the second rotation shaft 32b is in the non-powered state, and the connection state between the second auxiliary drive shaft 37b and the second rotation shaft 32b is in the transmission state.

When the rolled material 3 wound around the first mandrel 31a reaches a predetermined length, the rolled material 3 is cut by the cutter 20, but the control unit 55 controls the rolled material 3 by the cutting. ) to control the operation of the reel device 30 so that the winding is not stopped. That is, the control unit 55 switches the power source of the first mandrel 31a and the second mandrel 32a in order to continuously wind the material 3 to be rolled, so that the material 3 to be rolled is wound. It changes from the 1st mandrel 31a to the 2nd mandrel 32a.

More specifically, when the material to be rolled 3 wound around the first mandrel 31a approaches a predetermined length (before reaching), the control unit 55 increases the winding speed of the first mandrel 31a to 150 mpm. slow down to And in parallel with the said deceleration, the control part 55 drives the 1st auxiliary electric motor 36, and accelerates the 1st auxiliary clutch gear 44a to the rotation speed of 150 mpm.

That is, the control unit 55 reduces the rotation speed of the main motor 35 to 150 mpm, and adjusts the rotation speed of the first auxiliary motor 36 to the rotation speed of the main motor 35 (both rotation speeds). does not have to match completely, it just needs to match approximately). Accordingly, power is transmitted to the first auxiliary drive shaft 36b → the first auxiliary drive shaft gear 36d → the first auxiliary clutch gear 44a, and the first auxiliary clutch gear 44a rotates at a rotation speed of 150 mpm.

(Period B)

In the period B, the control unit 55 first, in a state in which the first auxiliary clutch gear 44a is rotating at a rotation speed of 150 mpm, brings the first clutch device 45a into contact with the first auxiliary clutch gear 44a. position, and the power source of the first mandrel 31a is switched. That is, the control unit 55 disconnects (off) the connection between the first clutch device 45a and the first main clutch gear 43a, and sets the first clutch device 45a and the first auxiliary clutch gear 44a. It is connected (on), and it changes so that power may be transmitted with the 1st auxiliary clutch gear 44a → 1st clutch device 45a → 1st rotation shaft 31b (1st mandrel 31a). That is, the control unit 55 switches the power source of the first mandrel 31a from the main motor 35 to the first auxiliary motor 36 . At this time, the connection state between the main drive shaft 35b and the first rotation shaft 31b becomes a non-motorized state, and the connection state between the first auxiliary drive shaft 36b and the first rotation shaft 31b becomes an electric state.

The control unit 55 controls so that the power source of the first mandrel 31a is switched to the first auxiliary motor 36, and then the rolled material 3 wound around the first mandrel 31a reaches a predetermined length ( control so as to be cut to a predetermined length by the cutter 20 ), and in this state, the material 3 to be rolled is cut by the cutter 20 . That is, in a state in which the first mandrel 31a is rotating at 150mpm by the first auxiliary motor 36 , the distal end of the rolled material 3 wound around the first mandrel 31a is connected to the cutter 20 . cut by

On the other hand, the stopped second mandrel 32a starts rotating by the second auxiliary motor 37 in parallel with the switching of the power source of the first mandrel 31a. That is, the control part 55 controls the state in which the second clutch device 45b is connected to the second auxiliary clutch gear 44b, that is, the second auxiliary drive shaft 37b → the second auxiliary drive shaft gear 37d → the second auxiliary. In a state in which power is transmitted with the clutch gear 44b → the second clutch device 45b → the second rotation shaft 32b (the second mandrel 32a), the second auxiliary motor 37 is accelerated to 150 mpm. That is, the control part 55 sets the rotation speed of the 2nd auxiliary motor 37 to a predetermined low rotation speed (150 mpm in this embodiment). At this time, the connection state between the main drive shaft 35b and the second rotation shaft 32b remains in a non-motorized state, and the connection state between the second auxiliary drive shaft 37b and the second rotation shaft 32b remains in an electric state.

(Period C)

In the period C, the control unit 55 first moves the second clutch device 45b to a position in contact with the second main clutch gear 43b, and switches the power source of the second mandrel 32a. That is, the control unit 55 disconnects (off) the connection between the second clutch device 45b and the second auxiliary clutch gear 44b, and sets the second clutch device 45b and the second main clutch gear 43b. By connecting (ON), the main drive shaft gear 35d → the second idle gear 42b → the second main clutch gear 43b → the second clutch device 45b → the second rotation shaft 32b (the second mandrel ( 32a)) and change to transmit power. That is, the control unit 55 switches the power source of the second mandrel 32a from the second auxiliary motor 37 to the main motor 35 . At this time, the connection state between the main drive shaft 35b and the second rotation shaft 32b becomes a motorized state, and the connection state between the second auxiliary drive shaft 37b and the second rotation shaft 32b becomes a non-motorized state.

The control unit 55 controls the starting end of the coil to reach the second mandrel 32a after the power source of the second mandrel 32a is switched to the main electric motor 35, and in this state, the belt wrapper Reference numeral 50 fixes the starting end of the coil to the second mandrel 32a.

Then, the control part 55 starts winding the to-be-rolled material 3 quickly by the 2nd mandrel 32a. That is, the power source of the second mandrel 32a is the main electric motor 35, and in a state where the second mandrel 32a is rotating at 150mpm, the second mandrel 32a start winding.

Then, the control unit 55 accelerates the rotation speed of the second mandrel 32a to 1200 mpm to wind the material 3 to be rolled, and the material to be rolled 3 wound on the second mandrel 32a is predetermined. When the length is approached, the same control as the control performed for the first mandrel 31a and the second mandrel 32a in the period A is applied to the second mandrel 32a and the first mandrel 31a. do That is, the control unit 55 realizes continuous winding of the rolled material 3 by using the first mandrel 31a and the second mandrel 32a alternately to wind the rolled material 3 . .

On the other hand, after winding the to-be-rolled material 3 on the 1st mandrel 31a to the distal end, the control part 55 inches the 1st mandrel 31a with the 1st auxiliary electric motor 36, An auxiliary operation for separating and dispensing the coil of the rolled material 3 wound around the mandrel 31a from the first mandrel 31a is performed (dispensing the coil). Therefore, at this time, the connection state between the main drive shaft 35b and the first rotation shaft 31b remains in the non-motorized state, and the connection state between the first auxiliary drive shaft 36b and the first rotation shaft 31b remains in the transmission state. do.

Thereafter, period D and period E continue, but since the switching operation of the clutch device in these periods is the same as the operation in periods B and C except that the first and second are exchanged, a detailed description is given below. omit

The reverse rolling mill 65 is an apparatus for rolling the material 3 to be rolled, and includes a pair of upper and lower rolling rolls 65w and a pair of upper and lower backup rolls 65u, and the material 3 to be rolled is, It is pressed and rolled by the rolling roll 65w. And in the rolling installation 60 which performs rolling with the reversing|reversing type rolling mill 65, the reel apparatus 30 and the exit winding unwinder (in the exit side of the reversing type rolling mill 65, the to-be-rolled material 3 is wound up) and the to-be-rolled material 3 are reciprocated between the apparatuses which perform unwinding, and the to-be-rolled material 3 is rolled several times with respect to the to-be-rolled material 3 by reciprocating and passing the to-be-rolled material 3 through the reversing|reversing type rolling mill 65 several times.

That is, when conveying and rolling the material 3 to be rolled from the upstream side to the downstream side, the first mandrel 31a is used for the first pass to unwind the material 3 to be rolled, and the second pass is after the second pass. It is performed using the mandrel 32a, and winding is performed using the exit winding unwinding machine. Conversely, when conveying and rolling the material 3 to be rolled from the downstream side to the upstream side, the unwinding of the rolled material 3 is performed using an exit winding unwinder, and winding is performed using the second mandrel 32a.

Therefore, the strip press 80 is provided just before the upstream side of the reversing|reversing-type rolling mill 65. As shown in FIG.

<<<About the operation of the reel device 30 according to the second embodiment >>>

Hereinafter, operation|movement of the reel apparatus 30 which concerns on 2nd Embodiment is demonstrated using FIG.2, FIG.4.

In the state shown in FIG. 4, the material to be rolled 3 before rolling is unwound (unwound) from the first mandrel 31a, and one end of the material 3 to be rolled (in FIG. 4, by reference numeral E1). ) shows a state in which the take-up take-up machine is not fixed yet. That is, from the state shown in Fig. 4, one end of the rolled material 3 is further conveyed downstream to the exit take-up unwinder, and one end of the rolled material 3 is fixed to the exit take-up unwinder, and the first mandrel 31a ) (unwinding) and the exit winding unwinder (winding), the rolling of the rolled material 3, the so-called first-pass rolling, is performed.

Accordingly, in the power transmission device 40 , the first clutch device 45a shown in FIG. 2 is connected to the first main clutch gear 43a , and the first mandrel 31a is the rolled material 3 ) is unwinding by the power of the main motor 35 .

On the other hand, the 2nd mandrel 32a shown in FIG. 4 is still in standby. That is, the second clutch device 45b is in a state not connected to the second main clutch gear 43b.

In the first pass rolling, the other end (the end opposite to the one end) of the material to be rolled 3 is separated from the first mandrel 31a serving as the unwinder, and the other end reaches the strip press 80 . is done until Then, in the rolling after the second pass, the other end of the rolled material 3 reaching the strip press 80 is moved to the second mandrel 32a and fixed to the second mandrel 32a, the second mandrel This is performed by reciprocating the material to be rolled 3 between the roll 32a and the exit winding unwinder.

Therefore, the power transmission destination of the main electric motor 35 is switched from the 1st mandrel 31a to the 2nd mandrel 32a between the completion of the 1st pass and the start of the 2nd pass. Specifically, in the power transmission device 40 , the connection between the first clutch device 45a and the first main clutch gear 43a is released, and the second clutch device 45b and the second main clutch gear 43b are released. ) is connected.

In the power transmission device 40 while the second and subsequent passes are being rolled in the second mandrel 32a and the exit winding unwinder, in the power transmission device 40, the first clutch device 45a and the first auxiliary clutch gear ( 44a) is connected, and in the first mandrel 31a, the first auxiliary motor 36 is used as a power source, and preparation for the next rolling is performed. That is, the coil of the material to be rolled 3 before rolling to be rolled next is provided in the first mandrel 31a, and one end of the coil of the material 3 to be rolled 3 provided in the first mandrel 31a is not shown. It is conveyed to the position of the nose bending apparatus (an apparatus which bends one end of the to-be-rolled material 3 so that one end may pass on a conveyance line smoothly) to the position, and preparation for next rolling is performed.

Then, between the second mandrel 32a and the exit winding unwinder, when the rolled material 3 is rolled to a target plate thickness, the rolled material 3 is rolled in the second mandrel 32a. It is wound in the shape of a coil, and rotation of both the 1st mandrel 31a and the 2nd mandrel 32a stops. Then, in the second mandrel 32a, the power source is changed in order to deliver the coil of the rolled material 3, and in the first mandrel 31a, the first pass of the next rolling is performed. The power source is changed to perform.

Specifically, in the power transmission device 40 , the connection between the first clutch device 45a and the first auxiliary clutch gear 44a is released, and the first clutch device 45a and the first main clutch gear 43a are released. is connected, the connection between the second clutch device 45b and the second main clutch gear 43b is released, and the second clutch device 45b and the second auxiliary clutch gear 44b are connected.

In this state, in the first mandrel 31a, the material to be rolled 3 is unwound by using the main electric motor 35 as the power source, and the first pass rolling is performed, and in the second mandrel 32a, The coil dispensing of the rolled material 3 is performed using the 2nd auxiliary electric motor 37 as a power source.

In this way, the rolling of the first pass in the first mandrel 31a and the coil delivery of the rolled material 3 in the second mandrel 32a are performed in parallel. That is, when the rolling of the 1st pass of the 1st mandrel 31a is complete|finished, the coil delivery of the to-be-rolled material 3 is completed in the 2nd mandrel 32a, and the 2nd mandrel 32a waits. is in the middle Therefore, the material to be rolled 3 is fastened to the second mandrel 32a, and rolling after the second pass is performed smoothly.

In addition, unlike the first embodiment, since the first auxiliary motor 36 (second auxiliary motor 37) is not used for driving the mandrel for winding or unwinding, the first auxiliary motor 36 ( The second auxiliary motor 37) may be smaller than that of the first embodiment (for example, an electric motor of about 11 kW).

=== About the effectiveness of the reel apparatus 30 etc. which concern on 1st Embodiment and 2nd Embodiment ===

As described above, in the reel device 30 according to the first embodiment (second embodiment), the winding ( It is a reel device 30 that performs unwinding and unwinding), and a main electric motor 35 having a main drive shaft 35b, a first mandrel 31a, and a first mandrel 31a to rotate together with the first mandrel 31a. A first auxiliary motor 36 having a first rotating shaft 31b coaxially coupled to the mandrel 31a, and a first auxiliary driving shaft 36b, for rotating the first rotating shaft 31b, and a second It has a mandrel (32a), a second rotation shaft (32b) coaxially coupled to the second mandrel (32a) to rotate together with the second mandrel (32a), and a second auxiliary drive shaft (37b), By selectively connecting the second auxiliary motor 37 for rotating the second rotating shaft 32b and the main driving shaft 35b and the first auxiliary driving shaft 36b with respect to the first rotating shaft 31b, the first 1 The main drive shaft 35b with respect to the said 2nd rotating shaft 32b while being comprised so that the power source of 1 mandrel 31a may be switched between the said main electric motor 35 and the said 1st auxiliary electric motor 36 ) and the second auxiliary drive shaft (37b), so that the power source of the second mandrel (32a) can be switched between the main motor (35) and the second auxiliary motor (37) It is assumed that the power transmission device 40 fixed on the foundation is provided. Therefore, compactness of the reel device 30 and cost reduction are possible.

A catheter having a first electric motor for rotating the first rotating shaft 31b of the conventional first mandrel 31a and a second electric motor for rotating the second rotating shaft 32b of the second mandrel 32a In the Russell type reel apparatus, a large electric motor was required for both the first electric motor and the second electric motor. For this reason, the reel apparatus has become huge, and the cost is increasing.

For example, when using a conventional carousel type winding machine as a winding machine on the exit side of a continuous rolling mill, since the output equivalent to the main motor 35 is required for both electric motors, for example, 2200x2=4400kW output was needed.

On the other hand, when the reel device of the present invention is provided as a take-up machine on the exit side of the continuous rolling mill (the first embodiment described above), the main electric motor is applied to the first mandrel 31a (the second mandrel 32a). (35) and the 1st auxiliary motor 36 (2nd auxiliary motor 37) are selectively connected and can be switched, so that the motor output of the reel apparatus 30 is the main motor 35 and the 1st auxiliary motor. The sum of (36) and the second auxiliary motor 37 is 2200+75+75=2350kW. That is, the reel apparatus 30 can suppress the output of the electric motor compared with the conventional reel apparatus.

In addition, in the case where the unwinder and the stand-side take-up unwinder are separately provided as in the prior art as the unwinding machine and the incoming-side take-up unwinder of the reversing type rolling mill, the unwinder and the input-side take-up unwinder have, for example, a unwinder of 500 kW, and an input winder. The output of the unwinder of 2000 kW corresponding to the main motor 35 is required, respectively. In this case, an output of 500+2000=2500kW is required.

On the other hand, when the reel device of the present invention is provided as an entry unwinder and an entry take-up unwinder of a reversing rolling mill (the second embodiment described above), the output of the electric motor of the reel device 30 is the main motor 35, The sum total of the 1st auxiliary motor 36 and the 2nd auxiliary motor 37 is set to 2000+11+11=2022kW. That is, the reel apparatus 30 can suppress the output of the electric motor compared with the conventional reel apparatus.

Moreover, a revolution mechanism was required for a carousel type winding machine, and the mechanical strength for each member to be able to withstand the revolution was also required. Therefore, the carousel type winding machine has a complicated structure and becomes a large-scale apparatus, and the reel apparatus is enlarged and the cost is increasing.

On the other hand, in the first embodiment, the reel device 30 in which the power transmission device 40 is fixed to the base is set as the winding machine. Therefore, in the winder which concerns on 1st Embodiment, the revolution mechanism like a carousel type winder is unnecessary, and the intensity|strength which can withstand revolution is not needed also for each member. That is, by making the reel device 30 according to the first embodiment as the reel device 30, it is possible to suppress the enlargement of the reel device (winder) and reduce the weight, so that the reel device can be made compact and the cost can be reduced.

In addition, the conventional reel device (unwinder) provided on the inlet side of the reversing mill has an output of, for example, 500 kW as described above, which is small compared to the output of the main electric motor 35 of the present invention, so the first pass There was a problem in that a sufficient rear tension was not obtained in the ridge, and the material to be rolled 3 was meandered. Moreover, the rolling speed of the to-be-rolled material 3 of the 1st pass was restrict|limited to 500 mpm or less, for example by the lack of output of the unwinder, and there existed a problem that productivity fell.

On the other hand, in 2nd Embodiment of this invention, the 1st mandrel 31a which uses the main electric motor 35 of 2200 kW as a power source can be used for unwinding. Therefore, in the second embodiment, it is possible to increase the rolling speed of the material 3 to be rolled in the first pass, and further, the meandering of the material 3 to be rolled in the first pass that has occurred in the prior art is reduced. It is suppressed, and it becomes possible to improve productivity.

In addition, in the first embodiment and the second embodiment, the power transmission device 40 has a function of switching the connection state between the main drive shaft 35b and the first rotation shaft 31b into an electric state and a non-electric state; A first clutch device 45a having a function of switching the connection state between the first auxiliary drive shaft 36b and the first rotation shaft 31b into an electric state and a non-electric state, and the main drive shaft 35b and the second rotation shaft 32b ) A second clutch having a function of switching the connection state between the electric state and the non-electric state, and a function of switching the connection state between the second auxiliary drive shaft 37b and the second rotation shaft 32b between the electric state and the non-electric state It was set as having the apparatus 45b.

That is, in the power transmission device 40, the switching of the main motor 35 and the first auxiliary motor 36 (the second auxiliary motor 37) is performed by the first clutch device 45a (the second clutch device 45b). )), it becomes possible to realize the compact and cost-reduced reel device 30 with a simple structure.

As described above, according to the present invention, there is provided a reel device that enables cost reduction and productivity improvement by simplifying and compacting the device structure.

That is, it was set as the rolling installation in which the reel apparatus 30 was provided in at least one of the exit side and the entry side of a rolling mill.

Accordingly, it is also possible to make the rolling equipment compact, to suppress the cost, and to improve the productivity.

Moreover, in 1st Embodiment, the continuous rolling mill 5 and the reel apparatus 30 are provided, and the reel is provided on the exit side which is the side from which the coil of the to-be-rolled material 3 after rolling by the continuous rolling mill 5 is delivered. It is a rolling method which performs rolling using the rolling equipment 1 provided with the apparatus 30, In the state which used the power source of the 1st mandrel 31a as the main electric motor 35, it uses the 1st mandrel 31a After winding the material 3 to be rolled 3 and reducing the rotation speed of the main motor 35 to 150 mpm, and adjusting the rotation speed of the first auxiliary motor 36 to 150 mpm, the first mandrel 31a Switching the power source from the main motor 35 to the first auxiliary motor 36, and in a state in which the first mandrel 31a is rotating at 150mpm, the rolled material 3 wound around the first mandrel 31a ), separating the coil of the rolled material 3 wound around the first mandrel 31a from the first mandrel 31a and dispensing it, and the power source of the second mandrel 32a. After setting the rotation speed of the second auxiliary motor 37 to 150 mpm in the state where the second auxiliary motor 37 is used, the power source of the second mandrel 32a is transferred from the second auxiliary motor 37 to the main motor 35 ), and using the main electric motor 35 as the power source of the second mandrel 32a, and the second mandrel 32a rotating at 150mpm, the material to be rolled with the second mandrel 32a It was set as the rolling method which starts winding of (3).

That is, according to this rolling method, in order to connect the main motor 35 to the mandrel for winding and connect the auxiliary motor to the mandrel for discharging the coil or preparing the next winding, work with both mandrels can be performed in parallel, and continuous winding of the rolled material 3 becomes possible.
