(Period A) In the period A, it is the state shown in FIG. 1, and the 1st mandrel 31a winds up the sheet-shaped to-be-rolled material 3 after being rolled into a roll shape. That is, in a state where the main motor 35 is used as the power source of the first spindle 31a, the first spindle 31a winds the material 3 to be rolled at a winding speed of 1200 mpm. This is a state where the first clutch device 45a shown in FIG. 2 is connected to the first main clutch gear 43a. In other words, the connection state between the main drive shaft 35b and the first rotation shaft 31b is the transmission state, and the connection state between the first auxiliary drive shaft 36b and the first rotation shaft 31b is the non-transmission state.

On the other hand, the second mandrel 32a shown in Fig. 1 is in a standby state for stopping. At this time, the second clutch device 45b shown in FIG. 2 is in a state of being connected to the second auxiliary clutch gear 44b. That is, in this state, the second clutch device 45b is located on the rear side than the position of the second clutch device 45b shown in FIG. 2. In other words, the connection state between the main drive shaft 35b and the second rotation shaft 32b is the non-transmission state, and the connection state between the second auxiliary drive shaft 37b and the second rotation shaft 32b is the transmission state.

When the material to be rolled 3 wound on the first mandrel 31a reaches a predetermined length, the material to be rolled 3 is cut by the cutter 20, but the control unit 55 prevents the rolling of the material to be rolled 3 The operation of the coiling device 30 is controlled by the method of stopping the cutting operation. That is, the control unit 55 is to continuously wind the material 3 to be rolled, and therefore switches the power source of the first mandrel 31a and the second mandrel 32a to change the winding action of the material 3 to be rolled from the first mandrel. The shaft 31a is changed to a second spindle 32a.

More specifically, the control unit 55 decelerates the winding speed of the first mandrel 31a to 150 mpm when the rolled material 3 wound on the first mandrel 31a approaches a predetermined length (before the predetermined length is reached). . In addition, simultaneously with this deceleration, the control unit 55 drives the first auxiliary motor 36 to accelerate the first auxiliary clutch gear 44a to the rotation speed of 150 mpm.

That is, the control unit 55 decelerates the rotation speed of the main motor 35 to 150 mpm, and at the same time adjusts the rotation speed of the first auxiliary motor 36 to the rotation speed of the main motor 35 (the rotation speeds of both do not have to be exactly the same, as long as they are approximately the same. ). Therefore, power is transmitted as 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, moves the first clutch device 45a to a position connected to the first auxiliary clutch gear 44a while the first auxiliary clutch gear 44a is rotating at a rotation speed of 150 mpm, and switches the first center The power source of the shaft 31a. That is, the control unit 55 disconnects (OFF) the first clutch device 45a and the first main clutch gear 43a, connects (ON) the first clutch device 45a and the first auxiliary clutch gear 44a, and changes the power transmission mode It is the first auxiliary clutch gear 44a→the first clutch device 45a→the first rotating shaft 31b (the first spindle 31a). That is, the control unit 55 switches the power source of the first spindle 31 a 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 is in the non-transmission state, and the connection state between the first auxiliary drive shaft 36b and the first rotation shaft 31b is in the transmission state.

The control unit 55 is a method in which the material to be rolled 3 wound on the first mandrel 31a reaches a predetermined length after the power source of the first mandrel 31a is switched to the first auxiliary motor 36 (only by cutting The machine 20 is controlled by cutting to a predetermined length, and in this state, the rolled material 3 is cut by the cutting machine 20. That is, the first mandrel 31a cuts the end portion of the rolled material 3 wound on the first mandrel 31a by the cutter 20 in a state where the first auxiliary motor 36 is rotating at 150 mpm.

On the other hand, the second spindle 32a that is stopped is performed simultaneously with the switching of the power source of the first spindle 31a, and the second auxiliary motor 37 starts to rotate. That is, the control unit 55 is in a state where the second clutch device 45b and the second auxiliary clutch gear 44b are connected, that is, the power is transmitted from the second auxiliary drive shaft 37b→the second auxiliary drive shaft gear 37d→the second auxiliary drive shaft gear 37d. 2 In the state of the auxiliary clutch gear 44b→the second clutch device 45b→the second rotating shaft 32b (the second spindle 32a), the second auxiliary motor 37 is accelerated to 150 mpm. That is, the control unit 55 sets the rotation speed of the second 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 is also maintained in the non-transmission state, and the connection state between the second auxiliary drive shaft 37b and the second rotation shaft 32b is also maintained in the transmission state.

(Period C) In the period C, the control unit 55 first moves the second clutch device 45b to the position connected to the second main clutch gear 43b, and then switches the power source of the second spindle 32a. That is, the control unit 55 disconnects (OFF) the second clutch device 45b and the second auxiliary clutch gear 44b, and connects the second clutch device 45b and the second main clutch gear 43b (ON), and changes the power transmission mode to The main drive shaft gear 35d→the second idle gear 42b→the second main clutch gear 43b→the second clutch device 45b→the second rotating shaft 32b (the second spindle 32a). That is, the control unit 55 switches the power source of the second spindle 32 a 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 is in the transmission state, and the connection state between the second auxiliary drive shaft 37b and the second rotation shaft 32b is in the non-transmission state.

The control section 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 motor 35, and in this state, makes the belt winding The machine 50 fixes the starting end of the coil to the second mandrel 32a.

After this is implemented, the control unit 55 quickly starts the winding of the material to be rolled 3 with the second mandrel 32a. That is, the main motor 35 is used as the power source of the second spindle 32a, and the winding of the material 3 to be rolled is started with the second spindle 32a while the second spindle 32a is rotating at 150 mpm.

Then, the control unit 55 accelerates the rotation speed of the second mandrel 32a to 1200 mpm to perform the winding of the material 3 to be rolled. When the material 3 to be rolled that has been wound on the second mandrel 32a approaches a predetermined length, The second spindle 32a and the first spindle 31a are controlled in the same manner as the control performed on the first spindle 31a and the second spindle 32a in the aforementioned period A. That is, the control unit 55 can realize the continuous winding operation of the material 3 to be rolled by alternately using the first mandrel 31a and the second mandrel 32a to wind the material 3 to be rolled.

On the other hand, the control unit 55, after the rolled material 3 has been wound on the first mandrel 31a to the end portion, the first auxiliary motor 36 makes the first mandrel 31a finely move (inching) for use It is an auxiliary operation (discharging the coil) of unloading and discharging the roll material of the rolled material 3 wound on the first mandrel 31a from the first mandrel 31a. Therefore, at this time, the connection state between the main drive shaft 35b and the first rotation shaft 31b is maintained in the non-transmission state, and the connection state between the first auxiliary drive shaft 36b and the first rotation shaft 31b is maintained in the Transmission status.

After that, the switching operation of the clutch device during the following period D and period E is continued, except that the first and second periods are replaced, the operation is the same as the operations in the periods B and C, so detailed descriptions are omitted.

===About the second embodiment === Next, the second embodiment will be described using Fig. 4. Fig. 4, the view direction corresponds to Fig. 1, and is a schematic view of the rolling equipment 60 of the second embodiment.

In addition, in Figure 4, in order to facilitate the description of the present invention, it is a drawing that abbreviates several devices such as the device for winding the rolled material 3 on the unwinder (unwinder) (in the In the following, descriptions of omitted devices and the like are also omitted. Also, in Figure 4, the horizontal direction of the paper is taken as the "X direction", the left side (right side) of the paper is referred to as "downstream (upstream)", and the longitudinal direction of the paper is referred to as the "Z direction". The upper side (lower side) of the paper is called "upper (lower)".

The difference between the above-mentioned first embodiment and the second embodiment is that: in the first embodiment, the coiling device 30 is on the unloading side (downstream side), that is, for discharging by continuous calendering The coiling device 30 is installed as a coiler on the load-out side of the coil of the rolled material 3 after being rolled by the machine 5. In the second embodiment, the coiling device 30 is on the loading side (upstream On the side), that is, on the loading side for supplying the roll of the material to be rolled 3 before being rolled by the reversal calender 65, the coiling device 30 is set at this point as a winding and unwinding machine.

The rolling equipment 60 in the second embodiment, as shown in FIG. 4, is provided with: a coiling device 30 having functions as a reeling machine and a loading side reeling and reeling machine, and a reverse-rotating calender 65, And a plate thickness measuring device 70, a strip press 80, and an unillustrated load-out side winding and unwinding machine. In addition, from the upstream side, the coiling device 30, the plate thickness measuring device 70, the strip press 80, the reversing calender 65, and the unwinding side winding and unwinding machine are installed in this order.

In the coiling device 30 included in the calendering equipment 60 of the second embodiment, the first mandrel 31a is a coil on which the material 3 to be calendered before calendering is installed, and is used to perform the first roll rolling. The second mandrel 32a is used for the rolling-out of the rolled material 3, and the second mandrel 32a is used for the rolling and unwinding of the rolled material 3 on the loading side after the second rolling.

The reverse calender 65 is a device for calendering the material 3 to be calendered. It is provided with a pair of upper and lower calender rolls 65w and a pair of back up rolls 65u. The material to be calendered 3 is calendered The roll 65w is pinched and rolled. In addition, in the rolling equipment 60 that is rolled by the inverted calender 65, the material to be rolled 3 is reciprocated between the coiling device 30 and the unwinding side winding and unwinding machine (on the unloading side of the inverting calender 65, using Between the device for coiling and unwinding the material 3 to be rolled, the material to be rolled 3 is rolled several times by passing the material to be rolled 3 through the reversal calender 65 several times.

That is, when the material to be rolled 3 is conveyed and rolled from the upstream side to the downstream side, the first rolling of the material to be rolled 3 uses the first mandrel 31a and the second rolling From now on, the second mandrel 32a is used, and the unwinding side reeling machine is used for reeling. Conversely, when the material to be rolled 3 is conveyed and rolled from the downstream side to the upstream side, the material to be rolled 3 is unrolled using the unwinding-side winding and unwinding machine, and the second mandrel 32a is used for rolling out the material to be rolled 3 Take-up.

The plate thickness measuring device 70 is a device for measuring the plate thickness of the material to be rolled 3, and is installed on the conveying line of the material to be rolled 3, between the second mandrel 32a in the X direction and the reversing calender 65, It is used to detect the thickness of the rolled material 3 moving back and forth.

The strip press 80 makes the end of the rolled material 3 (the beginning end of the coil of the rolled material 3 wound on the first mandrel 31a) from the first core during the rolling of the first pass. When the shaft 31a is disengaged, it is a device for pressing the material 3 to be slidable and maintaining the tension necessary for calendering to press the material 3 to be rolled to just before the reverse rolling calender 65. Therefore, the strip press 80 is installed in front of the upstream side of the reverse rolling type calender 65.

＜＜＜Regarding the operation of the coiling device 30 in the second embodiment＞＞＞ Hereinafter, the operation of the coiling device 30 in the second embodiment will be described using FIGS. 2 and 4. FIG.

The state shown in Fig. 4 shows that the material to be rolled 3 before being rolled out from the first mandrel 31a (unwinding the material to be rolled), and one end of the material to be rolled 3 (in Fig. 4, marked with the symbol E1) It has not been fixed to the unwinding machine on the unwinding side. That is, one end of the material to be rolled 3 is further conveyed downstream from the state shown in Fig. 4 to the unwinding side winding and reeling machine, and then one end of the material to be rolled 3 is fixed to the carrier The exit side coiling and reeling machine, and the rolling of the material 3 to be rolled between the first mandrel 31a (coiling) and the load side coiling and reeling machine (coiling), the so-called first-pass rolling .

Therefore, 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 spindle 31a is used to roll out the rolled material 3 by the power of the main motor 35 .

On the other hand, the second mandrel 32a shown in Fig. 4 is in a standby state for stopping. That is, the second clutch device 45b is not connected to the second main clutch gear 43b.

The rolling in the first pass is performed until the other end of the material 3 to be rolled (the end opposite to the above-mentioned one end) is separated from the first mandrel 31a as the unwinding machine, and the other end reaches the belt Material press 80 up. Then, after the second rolling, the other end of the material 3 to be rolled that has reached the strip press 80 is moved to the second mandrel 32a and fixed to the second mandrel 32a, and then the rolled material The material 3 reciprocates between the second mandrel 32a and the unwinding-side winding and unwinding machine.

Therefore, from the end of the first pass to the start of the second pass, the power transmission target of the main motor 35 is switched from the first spindle 31a to the second spindle 32a. Specifically, in the power transmission device 40, the first clutch device 45a is disconnected from the first main clutch gear 43a, and the second clutch device 45b is connected to the second main clutch gear 43b.

During the rolling after the second pass with the second mandrel 32a and the unwinder on the unwinding side, in the power transmission device 40, the first clutch device 45a and the first auxiliary clutch gear 44a are connected In the first spindle 31a, the first auxiliary motor 36 is used as a power source to prepare for the next rolling. That is, it is used to mount the roll material of the rolled material 3 before rolling to be rolled next to the first mandrel 31a, and transport one end of the roll material of the rolled material 3 mounted on the first mandrel 31a To the position of the unillustrated sheet edge first bending device (a device used to make one end of the rolled material 3 smoothly pass through the conveying line to bend the one end), prepare for the next rolling .

In addition, when the material to be rolled 3 is rolled to the target thickness between the second mandrel 32a and the unwinding machine on the unwinding side, the material to be rolled 3 after being rolled is tied to the second mandrel 32a. It is wound into a coil shape, and the rotation of both the first mandrel 31a and the second mandrel 32a is stopped. Then, in the second mandrel 32a, the power source is changed to discharge the rolled material of the rolled material 3 after rolling, and in the first mandrel 31a, the power source is changed to perform the first pass of the next rolling Rolled calendering.

Specifically, in the power transmission device 40, the first clutch device 45a is disconnected from the first auxiliary clutch gear 44a, the first clutch device 45a is connected to the first main clutch gear 43a, and the second clutch device 45b is disconnected from The connection of the second main clutch gear 43b connects the second clutch device 45b and the second auxiliary clutch gear 44b.

In this state, in the first mandrel 31a, the main motor 35 is used as the power source to roll the material 3 to be rolled out for the first roll rolling; in the second mandrel 32a, the second mandrel The auxiliary motor 37 serves as a power source to discharge the coil of the rolled material 3.

In this way, the rolling of the first roll in the first mandrel 31a and the discharge of the coil of the rolled material 3 in the second mandrel 32a are performed simultaneously and in parallel. That is, when the rolling of the first pass of the first mandrel 31a is completed, the discharge of the coil of the rolled material 3 in the second mandrel 32a is completed, and the second mandrel 32a is put on standby. Therefore, the fixing of the material to be rolled 3 toward the second mandrel 32a can be performed quickly, and the rolling after the second rolling can be smoothly performed.

Also, 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 (second auxiliary motor 37) is not used. The auxiliary motor 37) may be smaller than that of the first embodiment (for example, a motor of about 11 kW).

===Effects of the coiling device 30 of the first embodiment and the second embodiment === As described above, the coiling device 30 of the first embodiment (the second embodiment) performs the coiling (unwinding and coiling) of the material to be rolled 3 rolled by the continuous calender 5 (reverse calender 65). The coiling device 30 of unwinding) is provided with: A main motor 35 having a main drive shaft 35b, a first spindle 31a, a first rotating shaft 31b that is coaxially coupled to the first spindle 31a and rotatable with the first spindle 31a, and a first auxiliary drive The shaft 36b is used to rotate the first auxiliary motor 36 for rotating the first rotating shaft 31b, the second spindle 32a, and the second rotation that is coaxially coupled to the second spindle 32a and can rotate together with the second spindle 32a. The shaft 32b, a second auxiliary motor 37 having a second auxiliary drive shaft 37b and for rotating the second rotating shaft 32b, and a power transmission device 40 are fixed to the foundation so as to be relative to the first rotating shaft 31b. By selectively connecting the main drive shaft 35b and the first auxiliary drive shaft 36b, the power source of the first spindle 31a can be switched between the main motor 35 and the first auxiliary motor 36 The main drive shaft 35b and the second auxiliary drive shaft 37b are selectively connected with respect to the second rotating shaft 32b, so that the power source of the second spindle 32a can be connected to the main drive shaft. The motor 35 and the above-mentioned second auxiliary motor 37 are configured to switch between them. Therefore, the coiling device 30 can be compacted and the cost can be suppressed.

The conventional carousel type coiling device is provided with a first motor for rotating the first rotating shaft 31b of the first spindle 31a, and a second motor for rotating the second spindle 32a. As for the second electric motor that rotates the rotating shaft 32b, either the first electric motor or the second electric motor must be a large electric motor. Therefore, the coiling device is huge and the cost is increased.

For example, when using a conventional rotating rack type coiling device as a coiler on the unloading side of a continuous calender, since both motors must have an output equivalent to that of the main motor 35, it must be, for example, 2200 ×2=4400kW output.

In contrast, when the coiling device of the present invention is installed as a coiler on the unwinding side of a continuous calender (the first embodiment described above), the first mandrel 31a (the second mandrel 32a) is Since the main motor 35 and the first auxiliary motor 36 (second auxiliary motor 37) can be selectively switched and connected, the output of the motors of the winding device 30 is the main motor 35, the first auxiliary motor 36, and the second auxiliary motor 37 The total is 2200+75+75=2350kW. That is, the coiling device 30 can reduce the output of the motor compared with the conventional coiling device.

In addition, as the unwinding machine on the load side and the load side winding and unwinding machine of the reverse calender, if the unwinding machine and the load side winding and unwinding machine are separately installed as in the past, the The motors of the unwinding machine and the loading-side winding and unwinding machine must have, for example, 500kW for the unwinding machine and 2000kW for the loading-side winding and unwinding machine, which is equivalent to that of the main motor 35. In this case, it must have an output of 500+2000=2500kW.

On the other hand, when the coiling device of the present invention is installed as the unwinding machine on the load side and the unwinding machine on the load side of the reversing calender (the second embodiment described above), the coil device 30 is The output of the electric motor is the total of the main motor 35, the first auxiliary motor 36, and the second auxiliary motor 37, which is 2000+11+11=2022 kW. That is, the coiling device 30 can reduce the output of the motor compared with the conventional coiling device.

In addition, a revolving mechanism must be provided for a rotary rack type coiler, and each member must have a mechanical strength that can withstand the revolving motion. Therefore, the rotary rack type coiler becomes a huge device due to its complicated structure, and therefore the coiling device becomes huge and the cost increases.

On the other hand, in the first embodiment, the coiling device 30 to which the power transmission device 40 is fixed by the foundation is used as a coiling machine. Therefore, in the coiling machine in the first embodiment, it is not necessary to have a revolving mechanism like a rotating cradle type coiling machine, and it is not necessary to have the strength to withstand revolving rotation for each member. That is, by using the coiling machine of the first embodiment as the coiling device 30, the weight of the coiling device (coiler) can be reduced by suppressing the size of the coiling device (the coiling machine), so that the coiling device can be made compact and the cost can be reduced. .

In addition, the conventional coiling device (winding-out machine) installed on the loading side of the reverse rolling calender has an output of, for example, 500 kW as described above, which is smaller than the output of the main motor 35 of the present invention. It is not possible to obtain sufficient rear tension in one pass, and therefore, the problem of snaking of the rolled material 3 may occur. Furthermore, due to the insufficient output of the unwinding machine, the rolling speed of the material 3 to be rolled in the first pass is limited to, for example, 500 mpm or less, which causes a problem of reduced productivity.

In contrast, in the second embodiment of the present invention, the first spindle 31a using the main motor 35 of 2200 kW as a power source can be used for unwinding. As a result, in the second embodiment, the rolling speed of the material 3 to be rolled in the first roll can be increased, and furthermore, it is possible to suppress the snaking of the material 3 to be rolled in the first roll that occurred in the past. And can improve productivity.

In addition, in the first embodiment and the second embodiment, the power transmission device 40 is provided with: a first clutch device 45a and a second clutch device 45b; the first clutch device 45a has: a main drive shaft 35b The function of switching the connection state with the first rotating shaft 31b into the transmission state and the non-transmission state, and the function of switching the connection state between the first auxiliary drive shaft 36b and the first rotating shaft 31b into the transmission state and the non-transmission state Function; The second clutch device 45b has: the function of switching the connection state between the main drive shaft 35b and the second rotating shaft 32b to the transmission state and the non-transmission state, and the second auxiliary drive shaft 37b and the second rotation The connection state between the shafts 32b is a function of switching between the transmission state and the non-transmission state.

That is, in the power transmission device 40, by using the clutch mechanism of the first clutch device 45a (second clutch device 45b) as a switching mechanism between the main motor 35 and the first auxiliary motor 36 (second auxiliary motor 37), It is possible to realize a compact and low-cost coiling device 30 with a simple structure.

In this way, according to the present invention, it is possible to provide a coiling device that can reduce costs by simplifying and compacting the device structure, and can also improve productivity.

In addition, in the first embodiment (second embodiment), as the calendering equipment 1 (calendering equipment 60), a continuous calender 5 (reversing calender 65) and a coiling device 30 are provided, and will be borrowed A coiling device 30 is provided on the load-out side (load side on the side where the coil is supplied) where the coil of the rolled material 3 rolled by the continuous calender 5 (reverse type calender 65) is discharged. That is, as the rolling equipment, the coiling device 30 is installed on at least one of the loading side and the loading side of the calender.

Therefore, it is possible to achieve compactness and cost reduction of the rolling equipment, and it is also possible to improve productivity.

In addition, in the first embodiment, as the rolling method, the side of the coil that is provided with the continuous calender 5 and the coiling device 30 is used to discharge the rolled material 3 calendered by the continuous calender 5 as On the unloading side, use: the calendering equipment 1 provided with the coil device 30 on the unloading side to carry out the calendering method, and includes: In the state where the power source of the first mandrel 31a is the main motor 35, the step of winding the material 3 to be rolled by the first mandrel 31a, and the rotation speed of the main motor 35 is reduced to 150 mpm, and the first auxiliary motor After the rotation speed of 36 is matched with 150 mpm, the power source of the first spindle 31a is switched from the main motor 35 to the first auxiliary motor 36, and the first spindle 31a is rotated at 150 mpm, and the wound is taken up The step of cutting the end portion of the rolled material 3 on the first mandrel 31a, and unloading the rolled material of the rolled material 3 wound on the first mandrel 31a from the first mandrel 31a And when the power source of the second spindle 32a is the second auxiliary motor 37, the rotation speed of the second auxiliary motor 37 is matched to 150 mpm, and then the power source of the second spindle 32a is removed from the second auxiliary motor 37. 37. The step of switching to the main motor 35, and the power source of the second mandrel 32a is the main motor 35, and the second mandrel 32a is rotated at 150 mpm, and the second mandrel 32a is used to start the process of the rolling material 3 Steps of coiling.

That is, according to such a rolling method, since the main motor 35 is connected to the mandrel for winding and the auxiliary motor is connected to the mandrel for discharging the coil and performing the subsequent winding preparation work, it is possible to use The mandrels of both sides enable the work to be carried out simultaneously, thus making continuous coiling of the rolled material 3 possible.
