Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rolling mill guide device, and more particularly to a rolling mill guide device suitable for guiding thin plate materials such as aluminum foil.

As shown in FIGS. 1 and 2, a conventional rolling mill guide device has a fixed or movable plate 3 placed between two guide rollers 2, and an aluminum plate placed on top of the plate 3. It guides thin plate materials such as oil.

However, with such conventional equipment, thin plate materials, such as aluminum foil (hereinafter referred to as
When trying to roll the foil 1 (called a foil), the foil 1 has low bending rigidity and is weak, so the first
As shown in the figure, the tip of the foil 1 may get caught on the guide roller 2, causing it to bend, or in severe cases, as shown in Figure 2, it can easily break due to the frictional force between the foil 1 and the plate 3. The disadvantage is that it occurs in If a bend occurs, the operator has no choice but to feed the foil 1 using a long rod or pull it out using scissors. Therefore, when threading the board, it is necessary to use one to assist the threading.
~Two extra operators are required, making the process inefficient.

By the way, in order to thread the foil 1, there are two methods: grasping and pulling the tip of the foil 1 from the exit side of the rolling mill, and sending the rear end of the foil 1 toward the extrusion side from the entrance side of the rolling mill. In the conventional example described above, the latter method is adopted. Specifically, until the foil 1 is bitten by the rolling roll, the unwinding force due to the rotation of the unwinding reel is used, and after the foil 1 is bitten by the rolling roll, the rolling The foil was sent forward by the rotational force of the roll. For this reason, when the rolled material is weak, it bends or buckles as described above, and cannot be moved forward even if a further propulsion force is applied.

Therefore, the former method, which focused on guiding the rolled material by pulling it, was developed in 1973.
This is proposed in Publication No.-3652. However, this device is located on the exit side of the stand and must continue to drive the conveyor belt at a speed sufficient to apply a slight tensile force to the rolled material at all times during rolling. In this case, the movement of the conveyor belt must be delicately controlled, and if smooth movement cannot be achieved, it will only encourage bending or bending of the foil. Further, during rolling, the foil with low bending rigidity constantly comes into contact with the conveyor belt, so there is a problem that the foil is easily damaged. Furthermore, in order to prevent the foil from being squeezed, it is preferable to arrange rollers at short pitches and convey the foil while bending it, but it is impossible to provide rollers in the above device, and therefore , it is not possible to narrow down the results sufficiently.

The present invention has been developed in view of the above points, and its purpose is to, of course, be able to feed a thin plate material such as aluminum foil into a rolling mill.
To provide a new rolling mill guiding device capable of guiding a thin plate material by pulling it so that the thin plate material does not buckle even after leaving the rolling mill.

The present invention serves as a guide device for a rolling mill that guides a rolled material on both the entry side and exit side of the rolling mill, and includes a belt for guiding the rolled material and a drive device for rotationally driving this belt. The belt is constructed with a hollow part, and has a surface texture that allows the rolled material to be pulled by the frictional force with the rolled material, thereby achieving the intended purpose. This is what was done.

Hereinafter, the present invention will be explained based on the embodiments shown in the drawings.

FIG. 3 is a schematic diagram of the guide device showing the state in which the foil is being fed into the rolling mill, and FIG. 4 is a schematic diagram of the guide device showing the state in which the foil is being rolled.

In the figure, the foil 11 attached to the payoff reel 13 is rotated by the rotation of the payoff reel 13,
Then, it is rewound by the belt feeder 15 and guided to a belt guide 50a installed on the entry side of the rolling mill, which consists of upper and lower work rolls 21 and upper and lower reinforcing rolls 22. However, as it is, it does not reach the belt guide 50a, and the foil 11 hangs down due to its own weight and does not rest on the belt 5. For this purpose, a belt feeder air nozzle 16 is provided below the foil 11, and the foil 11 is pressed against the belt feeder 15 by air blown up from the air nozzle 16. When the belt 5 of the belt guide 50a is rotated in synchronization with the payoff reel 13, the foil 11 conveyed onto the belt 5 is pulled by the frictional force between the foil 11 and the belt 5 and sent to the rolling mill side. . Then, the foil 11 sent into the rolling mill is transferred to the work roll 2.
1 to a predetermined thickness, and sent to a belt guide 50b located on the exit side of the rolling mill, where the foil 11 is pulled and guided by the frictional force between the belt 5 and the foil 11, and is rolled to a tension reel. 28. In addition, if an air nozzle 20 is installed above the foil 11 that passes through the belt guides 50a and 50b installed on the inlet and outlet sides of the rolling mill, and air is injected into the foil 11, the inlet side of the rolling mill can be more reliably ,
The foil 11 can be pulled on the exit side. Of course, what is injected may be any gas and is not limited to air. Next, the configuration of the belt guides 50a and 50b installed on the inlet and outlet sides of the rolling mill will be explained. As shown in FIG. 5, the belt 5 is
Chains 6 are attached to both ends in the width direction of the belt with ends, and the belt has a partially hollow structure. belt 5
As shown in FIG. 6, the guide roller 17 that guides the roller has a shaft 8 driven by a chain 6 through a sprocket 7, and a roller body rotatably attached to the shaft 8 through a bearing 10. Consists of 9. Although not shown in detail, a sprocket is also attached to the shaft of the drive roller 18, so that the belt 5 can be driven by rotating the drive roller 18. Note that 19 is a presser roller for pressing the belt 5 against the drive roller 18. With this configuration, when feeding the foil 11 as described above, the belt 5 only needs to be positioned in advance so that the foil 11 can be placed on the upper surface of the belt 5, as shown in FIG. . In this way, the foil 1
1 can be caught in the work roll 21. Thereafter, the hollow portion of the belt 5 is positioned on the pass line, and the movement of the belt 5 is stopped. In this state, as shown in FIG. 8, the belt 5 and the foil 11 are no longer in contact with each other and are guided by the rotatable guide roller 17, so that while the belt 5 is being rolled, the work roll 21 and the payoff foil 1 are always
There is no need to rotate in synchronization with 3. Further, as shown in FIG. 4, a priddle roller 24 is located between the two guide rollers 17 and is movable in the vertical direction.
By providing this, it is possible to bend the foil 11, and the pitch of the bend can be made small, so that squeezing can be prevented. The foil 11 sent out through the work roll 21 is guided by a belt guide 50b arranged on the exit side and sent to the station reel 28. As shown in FIG. 4, when the bridle roller 24 is lowered, the guide roller 26 and payoff reel 13 are lowered.
and the belt guide 50a.
By moving downward, the foil 11 can be bent in short pitches.

Although the case where a belt with a chain is used has been described above, a part of the endless belt may be cut out to form a belt having a hollow portion, and this belt may be driven by a drive roller by friction transmission.

In this way, according to an embodiment of the present invention, belt guides in which a part of the belt that can be rotationally driven is hollowed out are arranged at the entrance and exit sides of the rolling mill, so that the foil can be rolled. When feeding the foil into the rolling machine or when feeding the foil from the rolling mill to the tension reel, the foil can be guided so as not to bend, and even during rolling the foil can be released from contact with the belt, so there is no damage to the foil. It won't stick or bend or buckle. Furthermore, since the belt guide can be stopped during rolling, delicate control of the belt guide is not required. Furthermore, by making the belt hollow, a bridle roll can be placed in this area, allowing the foil to be bent with a short pitch, which has the excellent effect of preventing the foil from being squeezed. be.

According to the rolling mill guide device of the present invention described above, the rolling mill guide device that guides the rolled material on both the entry and exit sides of the rolling mill includes a belt for guiding the rolled material, and a belt for guiding the rolled material. and a driving device for rotationally driving the belt, and the belt has a hollow part, and has a surface texture such that the rolled material is pulled by frictional force with the rolled material. Therefore, even if it is a thin sheet material such as aluminum foil, it is necessary to guide the thin sheet material by pulling it so that it does not buckle when it is fed into the rolling mill and even after it leaves the rolling mill. This is very effective for this type of guide device.
