Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an ironing roller for a metal foil rolling machine.

(Prior Art) Conventionally, for example, in the case of aluminum foil rolling, as disclosed in Japanese Utility Model Laid-Open No. 61-49752, wrinkles are prevented from occurring during winding of the aluminum foil, and the aluminum foil during winding is prevented. In order to stabilize the above condition, an ironing roller having a rubber lining roller and a steel roller pressed against the foil surface of the aluminum foil wound on the winding coil is used.

Both rollers are attached to a frame pivotally mounted on a roll stand of a rolling mill so that they can rotate freely, and are lifted and lowered by a cylinder that vertically swings the frame. Will be pressed against the foil surface at the same time.

Of these rollers, the rubber lining roller rotates while sticking to the foil surface, and is effective in preventing coil misalignment and soft winding mainly during acceleration and high-speed rolling. Is arranged in the vicinity of the coil winding contact so as to press the metal foil on the slightly downstream side thereof.

On the other hand, since the steel roller can be pressed against the coil more strongly than the rubber lining roller, it is particularly effective in preventing winding deviation or soft winding of the coil at the beginning of winding.

However, if both rollers are attached to one frame, both rollers will always be pressed against the foil surface at the same time, so by controlling the steel roller independently from the rubber lining roller, the characteristics of both rollers will be considered. And it is not possible to use them properly according to need.

Therefore, for example, as shown in Japanese Utility Model Laid-Open No. 63-34508, a steel roller and a rubber lining roller are pivotally attached to the tips of separate independent frames, so that they can be used properly considering the characteristics of both rollers. The ironing roller has been developed.

(Problems to be solved by the invention) However, in the ironing roller disclosed in Japanese Utility Model Laid-Open No. Sho 63-34508, the steel roller is more effective than the rubber lining roller arranged slightly downstream of the coil winding contact. Since it is arranged on the downstream side, there is a disadvantage that the steel roller and the frame supporting it are obstructive for taking out the coil after the winding is completed, which makes the taking out work difficult.

That is, since the rolling stand is adjacent to the upstream side of the take-up reel, the downstream side of the take-up reel needs to be secured as a coil carry-out space. If a frame that supports the coil is placed, the coil carry-out space is damaged and it becomes difficult to take out the coil.

On the other hand, in the ironing roller described in the publication, both rollers are simply rotatably provided.
Even if both rollers are pressed against the coil when an abnormality such as foil breakage occurs or when the line is decelerated, it is difficult to prevent the looseness of the rollers.

In view of such a situation, the present invention makes it possible to selectively use the steel roller and the rubber lining roller in consideration of the characteristics of the steel roller and the rubber lining roller without making the work of carrying out the coil difficult.
The purpose is to be able to quickly respond to foil breaks and line deceleration.

(Means for Solving the Problem) The present invention provides the metal foil on the downstream side of the metal foil rolling machine such that the winding contact is rotated around the lateral axis and is located above the axis. A take-up reel is provided, and a rubber lining roller and a steel roller that are pressed against the foil surface of the metal foil from above are provided above the take-up reel so as to be vertically movable by a cylinder. In an ironing roller of a metal foil rolling machine arranged so as to press a metal foil on a slightly downstream side of the winding contact, the steel roller has a brake function for stopping its rotation, and the cylinder A second cylinder that operates independently with respect to the rubber lining roller arranged on the upstream side of the rubber lining roller arranged slightly downstream of the winding contact. The chromatography la are those independently provided so as to be pressed against the foil surface.

(Operation) The steel roller 7 has the function of the brake 26 for stopping its rotation, and can be pressed against the foil surface of the metal foil 4 independently of the rubber lining roller 8 by the second cylinder 30. At the time of foil winding, the rotatable steel roller 7 is coiled together with the rubber lining roller 8.
The steel roller 7 is pressed against the coil 35 when pressed at 35 and stable at high speed.
And use only the rubber lining roller 8
By pressing the steel roller 7 on which the brake 26 is applied at the time of foil break or deceleration, the steel roller 7 can be used for various purposes.

In this case, since the steel roller 7 having the above-mentioned function is provided on the upstream side of the rubber lining roller 8 which presses the metal foil on the slightly downstream side of the winding contact point, the steel roller 7 after the winding is completed. Does not interfere with the work of carrying out the coil 7.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

1 and 2 show an aluminum foil rolling machine to which an ironing roller 1 according to the present invention is applied, and a pair of upper and lower work rolls 3 supported by a back-up roll 2 on the back side.
The aluminum foil 4 is rolled with, and the rolled aluminum foil 4 is guided by the bridle roller 5 to be wound on the spool of the take-up reel 6, and the foil surface of the coil 35 wound on the take-up reel 6 is also annealed. It is adapted to be pressed by the roller 1.

The ironing roller 1 has a steel roller 7 and a rubber lining roller 8, and the steel roller 7 is arranged upstream of the rubber lining roller 8. The rubber lining roller 8 presses against the coil 35 during acceleration and high speed rolling to prevent winding deviation and soft winding.
Is arranged so as to press the downstream side (rear side) of the winding contact which is in contact with.

On the other hand, the downstream side (rear side) of the rubber lining roller 8 is the carry-out side of the winding coil 35, and there is no space for installing the steel roller 7.

That is, since the rolling mill stand is adjacent to the upstream side (front side) of the take-up reel 6, the downstream side (rear side) of the take-up reel 6 needs to be secured as a carry-out space for the coil 35. Therefore, if the steel roller 7 and a member that supports the steel roller 7 are arranged on the downstream side of the take-up reel 6, the take-out space of the coil 35 is affected and the take-out work becomes difficult.

Therefore, in this embodiment, the steel roller 7 is arranged on the upstream side of the rubber lining roller 8 that presses the coil 35 near the winding contact.

The rubber lining roller 8 is rotatably attached to the tip of a swing arm 9, and the swing arm 9 is pivotally supported by a lift frame 10 so as to be swingable up and down, and between the lift frame 10 and the lift frame 10. The rubber lining roller 8 is constantly coiled through the load cell 13 by the spring 12 interposed in the coil 35.
It is biased to press. The swing arm 9
An oil damper 14 is provided between the lifting frame 10 and the lifting frame 10. The lifting frame 10 is the roll stand 15 of the rolling mill.
A guide rod (17) of a support bracket (16) extended from the above is supported so as to be able to move up and down via a slide bearing (18), and an elevation cylinder (19) pivotally attached to the support bracket (16) can raise and lower along the guide rod (17).

The steel roller 7 is rotatably supported by an elevating frame 20 by a roll shaft 21, and the elevating frame 20 is movably supported by a guide rod 22 provided in parallel with the guide rod 17 via a slide bearing. As shown in FIG. 3, the roll shaft 21 includes a pair of left and right brackets 23 of the lifting frame 20.
Is supported via a spherical bearing 24 on the roll shaft 21,
The steel roller 7 is rotatably fitted through a pair of left and right ball bearings 25. A pair of left and right air brakes 26 are installed between the roll shaft 21 and the steel roller 7 so as to be located outside the ball bearing 25. Each air brake 26 includes an air passage 27 formed in the roll shaft 21 and a joint 2
8. It is connected to an air source (not shown) through a flexible hose 29, etc., so that the rotation of the steel roller 7 can be stopped when the compressed air is supplied.

The elevating frame 20 is connected to a pressing cylinder 30 for independent operation, and the pressing cylinder 30 is connected to an elevating cylinder 31 pivotally attached to the support bracket 16. Therefore, the entire lifting frame 20 side moves up and down along the guide rod 22 by the expansion and contraction of the elevating cylinder 31, and the expansion and contraction of the pressing cylinder 30 causes the steel roller 7 to press independently of the rubber lining roller 8. Move up and down.

In this embodiment, the elevating cylinders 19 and 31 are hydraulic, and their positions are controlled in synchronization with the increase in the diameter of the coil 35 due to winding. The pressing cylinder 30 is of the air type and is controlled independently of the lifting cylinders 19 and 31, and constitutes a second cylinder for the lifting cylinders 19 and 31.

Next, the operation will be described. When rolling the aluminum foil 4, the steel roller 7 and the rubber lining roller 8 are pressed against the foil surface of the coil 35 at the start of winding. That is, the steel roller 7 is moved up and down by the lifting cylinder 31 and the pressing cylinder 30. The elevating cylinder 31 detects the coil diameter of the take-up reel 6 and controls the position according to the coil diameter. At the controlled position, the pressing cylinder 30 is controlled under an appropriate pressing load, and the pressing roller 30 is used to move the steel roller 7 to the aluminum foil 4
Press on. On the other hand, the rubber lining roller 8 is position-controlled by the elevating cylinder 19 and is pressed against the coil 35 by the spring 12. At this time, the oil damper 14 absorbs the vibration, and the load cell 13 detects the pressing force to perform highly accurate pressing force control.

Thus, when the steel roller 7 is pressed against the coil 35 together with the rubber lining roller 8 at the beginning of the foil winding, the coil 35 of the take-up reel 6 can be made into a perfect circular coil. Therefore, if acceleration is performed thereafter, vibration can be reduced and soft winding and winding misalignment can be prevented.

During acceleration and high speed rolling, the lift cylinder 31 is position-controlled by detecting the coil diameter of the winding reel 6, and the pressing cylinder 30 raises the steel roller 7 to a position slightly above the coil 35. At this time, the air brake
26 is actuated to brake the steel roller 7 and put it in a standby state. On the other hand, since the rubber lining roller 8 is in the pressed state, the restraint force and the vibration caused by the rubber lining roller 8 are absorbed to prevent the winding of the air, whereby the winding deviation or the soft winding of the coil 35 of the winding reel 6 can be prevented. Therefore, it does not hinder high speed rolling.

When the aluminum foil 4 is broken or when decelerating, the pressing cylinder 30 is operated separately from the lifting cylinder 31, and the steel roller 7 is pressed against the coil 35 of the take-up reel 6 while the brake is applied to prevent the winding from loosening. To do. In this case, since only the pressing cylinder 30 needs to be operated as compared with the case where the whole is operated, it can be operated at a high speed and is particularly effective when the foil is cut. Therefore, high-speed rolling is possible and productivity is improved.

The coil diameter of the take-up reel 6 may be directly detected by a photoelectric switch or the like, or may be calculated from the foil speed on the delivery side of the aluminum foil 4 and the rotation speed of the take-up reel 6.

Further, the signal at the time of deceleration may be obtained from the push button operation for deceleration, the coil diameter of the rewinding coil, the coil diameter of the take-up reel 6, and the like.

In addition, in the above-described embodiment, the example in which the two lifting cylinders 19 and 31 are separately provided has been exemplified, but as shown in FIG.
The lifting cylinder 32 may be shared, and the pressing cylinder 30 may be provided separately from the lifting cylinder 32.

Further, although the steel roller 7 and the rubber lining roller 8 are shown as idle type, they are not limited to these and may be driven by a DC electric motor.

For example, as shown in FIG. 5, the rubber lining roller 8 is connected to one end of the electric motor through the universal spindle 33.
The peripheral speed of the roller 8 is controlled by the signal from the speed detector which connects 34 and detects the foil speed on the output side of the aluminum foil 4.
The speed of the electric motor 34 may be controlled to be slightly slower (about 0 to 5%) than the foil speed. By doing so, a slight slip occurs between the rubber lining roller 8 and the aluminum foil 4, so that the effect of squeezing out the air that is about to be wound into the winding coil 35 is large, and the soft winding due to the winding of the air is large. At the same time, there is no winding deviation and high-speed rolling becomes possible.
Further, when foil breakage occurs, if the speed is further reduced and a speed difference of 5% or more is applied, the loosening of the winding coil 35 can be more reliably prevented by the braking effect.

In the embodiment, the lifting cylinders 19 and 31 are hydraulic, and the positions are controlled in synchronization with each other, but as an air type, it is also possible to control the positions of only the lifting cylinder 31 and to control the lifting pressure of the lifting cylinder 19. .

According to the present invention, the steel roller 7 having the brake 26 function is provided.
Since it can be pressed against the foil surface of the metal foil 4 independently of the rubber lining roller 8, it can respond not only at the start of rolling or at high speed stability but also at the time of foil breaking or deceleration of the line, and the steel roller 7 Is provided on the upstream side of the rubber lining roller 8 which is disposed on the slightly downstream side of the winding contact, and the steel roller 7 is provided after the winding is completed.
Does not obstruct the transfer side of the coil 35 and does not hinder the operation, so that various uses can be made in consideration of the characteristics of the steel roller and the rubber lining roller without causing difficulty in the work of carrying out the coil 35.
