Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for carrying out a desired treatment on a strip material, such as a rolled material, which is formed in a thin strip shape by transporting the strip material through rollers inside a treatment tank. More particularly, the present invention relates to an improvement in a power transmission mechanism for a roller provided inside a processing tank.

[0002]

2. Description of the Related Art For example, a metal strip material immediately after being manufactured by a rolling mill is in a state where oil and other foreign substances supplied during rolling are attached thereto, and it is necessary to thereafter perform a treatment such as degreasing or washing. . In addition, various kinds of processing may be performed on a strip material other than metal, such as paper, cloth, resin, and the like during the manufacturing process.

[0003] As an apparatus for performing such processing of a strip material, a plurality of rollers are disposed inside a processing tank, and the strip material is immersed in a processing liquid while the strip material is conveyed in an appropriate direction through these rollers. In general, the processing liquid is sprayed or the processing liquid is sprayed.

In this type of foil and strip material processing apparatus, the above-described processing tank is usually disposed between an unwinder for unwinding the strip material and a winder for winding the strip material. The removing machine applies tension to the processed strip material and conveys the strip material. Also,
The transport speed of the strip material is also adjusted by appropriately changing the rotation speed of the unwinder.

[0005]

By the way, in the above-described processing apparatus for a foil and a strip material, the starting point of the strip material is taken from the unwinder to the winding machine via the rollers arranged in the processing tank. During this time, tension cannot be applied to the strip material. Therefore, the productivity is remarkably reduced, for example, the worker himself has to perform such work.

[0006] For this reason, the productivity is improved by rotating the rollers disposed inside the processing tank and efficiently performing the above-described operation until the start end of the strip material is wound by the winder. There is a strong need for the development of a processing device for foil and strip material that can be used. Furthermore, in this case, the rotation drive of each roller is controlled so as not to apply harmful tension to the strip material due to the influence of mechanical loss or inertia force of the roller, for example, even for a very thin strip material of about several μm. It is desired that a desired treatment can be performed without causing breakage of the steel.

[0007] However, in this type of processing apparatus for a foil and a strip material, a treating solution for treating the strip material may be a chemical having corrosive properties such as strong acidity or strong alkalinity.
Alternatively, a combustible chemical may be used, and since the inside of the processing tank is often kept in a high temperature and high humidity state, a rotary actuator such as an electric motor serving as a drive source of the roller is mounted on the processing tank. There is a restriction that it cannot be placed inside. In addition, these treatment liquids are often harmful to human bodies and peripheral devices, and it is necessary to reliably prevent the treatment liquid from leaking out of the treatment tank.

Conventionally, in response to such demands, a hole is provided in the wall of the processing tank to expose the shaft end of each roller to the outside, and each roller is driven by a rotary actuator disposed outside the processing tank. A rotating and processing apparatus for foil and strip material is provided.
By applying torque control mainly based on speed called helper control for the rotation drive of the roller, it is possible to perform the desired processing even on a very thin strip material without causing breakage. And Further, an appropriate sealing means is interposed between the wall of the processing tank and the shaft of the roller to prevent the processing liquid from leaking outside.

[0009] However, the implementation of the above-mentioned helper control requires a high-performance electric motor and a complicated control device, resulting in a significant increase in the manufacturing cost. In addition, management of software for controlling requires special technical skills, and maintenance of a processing apparatus for foil and strip material requires a large cost.

On the other hand, the above-mentioned sealing means causes a troublesome disassembling operation for maintenance and replacement of the roller, and the stricter the sealing property, the more complicated the operation becomes. That is, when the treatment liquid is completely prevented from leaking out, the disassembling operation accompanying the maintenance and replacement of the roller is made difficult. On the other hand, when the disassembling operation is facilitated, the treatment liquid leaks out. It is difficult to completely prevent such situations from occurring. As a result, fumes and mist of the processing liquid remain leaked from the processing tank that is configured to inject the processing liquid through the gap of the sealing means. Rollers placed in a processing tank that sprays a processing liquid that does not allow even fumes and mist to leak out, or a processing tank that sprays a processing liquid that must not be exposed to the outside air In fact, the rollers immersed in the processing liquid in the processing tank cannot be driven to rotate at all. In addition, if the sealing property of the sealing means is made strict, this also increases the mechanical loss of the roller, and further complicates the helper control described above.

According to the present invention, in view of the above circumstances, the roller disposed inside the processing tank can be rotated without significantly increasing the application cost, complicating the maintenance and inspection work, and preventing the processing liquid from leaking to the outside. It is an object of the present invention to provide a processing apparatus for a foil and a strip material which can be driven and furthermore can easily control the rotational driving of the roller.

[0012]

SUMMARY OF THE INVENTION According to the present invention, a strip and strip material processing apparatus is provided in which a strip material is conveyed through a roller inside a processing tank to perform a desired process on the strip material. In the above, a power transmission body for transmitting a rotational force by mutual magnetic force is provided at a portion opposed to each other across a wall constituting the processing tank, and a power transmission body provided inside the processing tank is linked to the roller. On the other hand, a power transmission member provided outside the processing tank is linked to a drive source.

As the power transmission body, a disk-shaped one in which permanent magnets are juxtaposed at a plurality of positions opposed to each other is applied, and one of the power transmission bodies is fixed to the shaft end of the roller, and the other is fixed to the shaft end. The drive source may be fixed to an output shaft end.

More specifically, a pair of guide rods 56 are provided on the bearing bracket 55, and a pair of guide bushes 57 are provided on the unit frame 50, and these guide rods 56 are slidably inserted into the guide bushes 57, respectively. By doing so, the vertical movement of the bearing bracket body 55 is guided. Further, a rack 56a is provided at the upper end of each guide rod 56, and a pinion gear 58 is meshed with each of the racks 56a, and each pinion gear 58 is fixed to a common pinion shaft 58a. It is configured to always work together.

Driving rollers disposed at both ends of the unit frame 50 (hereinafter referred to as both ends driving roller 60C as appropriate).
Is a lower horizontal frame 52 as shown in FIGS.
The bearings 59 are rotatably supported by bearing brackets 59 projecting upward from both ends via bearings 61, respectively.
The height position of each of the both-end drive rollers 60C is defined such that the upper peripheral surface thereof is at the same height position as the upper peripheral surface of the central drive roller 60A described above.

The two-end driving roller 60C includes
Each is provided with an auxiliary roller 60s. Auxiliary roller 6
0 s is rotatably supported via the respective bearings 61 on an auxiliary bearing bracket 55 s independent from the unit frame 50, similarly to the above-described lifting drive roller 60 </ b> B, between the unit frame 50. It can be moved up and down by the operation of the interposed auxiliary lifting air cylinder actuator 62s. These auxiliary rollers 60s

It will be arranged at the position where it comes into contact with the surface. The lifting drive roller 60B is also provided between the auxiliary bearing bracket 55s and the unit frame 50.
The same guide means as in the case (1) is provided. That is, a pair of auxiliary guide rods 5 are attached to the auxiliary bearing bracket 55s.
6s, while a pair of auxiliary guide bushes 57s is provided on the unit frame 50, and these auxiliary guide rods 56s are slidably fitted into the auxiliary guide bushes 57s, respectively, to thereby raise and lower the auxiliary bearing bracket 55s.

The pinion gears 58s are meshed with the racks 56as, and the pinion gears 58s are fixed to a common pinion shaft 58as, so that the two auxiliary guide rods 56s are always linked.

As can be seen from the figure, the bearings 61 of the above-described drive rollers 60 have one end, which is on the same side as each other, exceeding the central bearing bracket 54, the bearing bracket body 55, and the both-end bearing bracket 59, respectively. And a power transmission body 63 is provided at each protruding end. The power transmission body 63 is shown in FIG.
As shown in FIG. 2 and FIG. 2, each of the plurality of permanent magnets 64 is buried radially outward from the bearing 61, and a plurality of permanent magnets 64 are buried at a plurality of locations on each end face. is there. The permanent magnets 64 each have a disk shape, and are arranged side by side along a predetermined arc so that the same magnetic poles appear.

The power transmission body 63 of each of these drive rollers 60
Are fixed to the respective bearings 61 in a state where the end face in which the permanent magnets 64 are embedded is brought close to the inner wall surface of the processing tank 20, and the magnetic force of each permanent magnet 64 reaches the outside through the side wall 23 of the processing tank 20. It is like that. Here, the processing tank 20
When the processing tank 20 is made of a material having a low magnetic permeability, the magnetic force of the permanent magnet 64 does not sufficiently reach the outside. After cutting out the portion where the body 63 faces, it is preferable to seal the portion with a plate made of a material having high magnetic permeability.

The fluid injection nozzle 70 is for injecting the processing liquid between the above-mentioned drive rollers 60 onto both the upper and lower surfaces of the metal strip material S. As shown in FIGS. It is arranged at an appropriate position on a fluid supply pipe 71 arranged along the axis of 60. The fluid supply pipe 71 is held by the lower horizontal frame 52 and the connecting vertical frame 53 of the unit frame 50, and is connected to a processing liquid supply source through a supply passage (not shown). The reason why the fluid supply pipe 71 is connected to the supply source of the processing liquid is that the metal strip S is subjected to the first degreasing, cleaning and rust-prevention treatment.
In the fifth strip material processing apparatus 100 that performs only the fourth to the fourth strip material processing apparatus 100 and performs the drying process, an air blow (not shown) is connected to the fluid supply pipe 71 via a heating source, Warm air is injected from the fluid injection nozzle 70 to the metal strip material S.

On the other hand, the strip material processing apparatus 100
The processing tank 2 serves as a drive source of the drive roller 60 described above.
0, a rotary actuator 80 such as an electric motor or an air motor is provided. Rotary actuator 8
Numerals 0 are individually provided for the drive rollers 60 accommodated in the respective processing tanks 20, and each of the output shafts 81 is provided with a power transmission body 82. As shown in FIGS. 1 and 2, the power transmission body 82 has the same configuration as the power transmission body 63 provided on the bearing 61 of each drive roller 60. However, the orientation of the permanent magnet 83 is arranged such that the opposite magnetic pole appears between the permanent magnet 64 and the permanent magnet 64 provided on the power transmission body 63 of the drive roller 60 so that an attractive force is exerted by the mutual magnetic force. .

Among these, the rotary actuator 80 for the central drive roller and the rotary actuator 80 for the both-end drive roller make the axis of the output shaft 81 coincide with the axis of the corresponding drive roller 60 and transmit the power, respectively. The body 82 is attached to the main frame 10 in a state where the end face is close to the outer wall surface of the processing tank 20. On the other hand, the rotary actuator 80 for the lifting drive roller is
Output shaft 8 on the basis of the case in which
1 is aligned with the axis of the lifting drive roller 60B,
The power transmission members 82 are attached to the main frame 10 with the end faces of the power transmission members 82 being close to the outer wall surface of the processing tank 20.

Reference numeral 200 in FIG. 7 denotes a tension applying roller for preventing the metal strip material S wound by the winder 2 from becoming loose due to air entrapment or the like. Reference numeral 300 denotes a device for supplying paper for preventing frictional damage between the metal strip materials S to be wound on the winder 2.

In the strip material processing apparatus 100 constructed as described above, the metal strip material S unwound from the unwinding machine 1 has five stages of drive rollers until it is wound up by the winding machine 2. The metal strip material S is successively subjected to degreasing, cleaning and rust-prevention treatment by injecting a treatment liquid from the fluid ejection nozzle 70, and further injects hot air from the hot air injection nozzle. As a result, the metal strip material S after the cleaning is subjected to a drying process. In this case, in the processing tank 20 of the first to fourth strip material processing apparatuses 100,
It is preferable that the inside of the processing tank 20 be maintained at a high temperature in order to activate the processing liquid, or that the inside be maintained at a high pressure by supplying an inert gas such as nitrogen from the gas supply hole 31 of the lid 30. Further, in all or a part of the first to fourth strip material processing apparatuses 100, the processing liquid injected from the fluid injection nozzle 70 is stored in the processing tank 20, and the metal strip material S is immersed therein. By doing so, a degreasing, cleaning and rust-preventing treatment may be performed. However, it goes without saying that the processing liquid to be stored is kept at a level sufficiently lower than the passage opening 23a. In addition, at this time, it is preferable to move the lifting drive roller 60B downward, particularly when the metal strip material S is a foil that is difficult to stand by itself in shape. That is, the lifting drive roller 60B
Is moved downward, the driving rollers 60A, 60B,
Since the transport path of the metal strip material S constituted by 60C constitutes peaks and valleys, the metal strip material S is appropriately guided, and the occurrence of wrinkles or breaks caused by the wrinkles is effective. Can be prevented.

According to the strip material processing apparatus 100 described above, when each of the rotary actuators 80 is driven, the rotational force is applied to the permanent magnet 64 of the power transmission body 82 provided on the output shaft 81 and to each of the drive rollers. The power is transmitted to the drive roller 60 by a mutual magnetic force between the power transmission body 63 and the permanent magnet 83 provided in the power transmission body 60.

Therefore, between the both-end driving roller 60C and the auxiliary roller 60s, it is possible to apply a conveying force to the metal strip S, and even at the start end of the metal strip S, it is wound. It can be easily transported to the picking machine 2 and the work efficiency during this time can be improved.

Moreover, since each drive roller 60 is driven to rotate while being physically separated from the rotary actuator 80, even if the unwinding or winding speed changes, the metal strip material is not used. The influence of mechanical loss and inertia force on S can be made as small as possible. Therefore, when a general-purpose electric motor or air motor is applied as the above-described rotary actuator 80, each driving roller 6 can be further controlled by using an extremely simple control method.
Even when the zero rotation drive is controlled, there is no fear that harmful tension is applied to the metal strip material S. As a result, an effect equivalent to that of the helper control can be obtained without causing a remarkable increase in application cost. For example, even for a very thin metal strip material S having a thickness of about several μm, It becomes possible to perform the degreasing, washing, rustproofing and drying treatments. The vertical movement of the lifting drive roller 60B is also separated from the rotary actuator 80 and only the bearing bracket 55 is interlocked, so that the height position can be quickly changed according to the passing state of the metal strip material S. Will be able to

Further, it is not necessary to provide the processing tank 20 with a hole for exposing the bearing 61 of the drive roller 60 to the outside and a means for sealing the hole.
Therefore, there is no danger that not only the processing liquid sprayed and stored in the processing tank 20 but also its fumes and mist may leak to the outside, which may adversely affect peripheral devices such as the rotary actuator 80 or the external atmosphere. Can be effectively prevented. In addition, in the disassembling operation accompanying the maintenance and replacement of the drive roller 60, if the cover 30 is removed and the processing tank 20 is opened, all of the five-stage drive rollers 60 are removed from the processing tank 20 together with the unit frame 50. Because it can be removed, it can be implemented very easily.

In the above-described embodiment, the processing device for the foil and the strip material for performing the processing on the metal strip material after being rolled and manufactured by the rolling mill is exemplified. However, the present invention is not limited to this. The present invention is not limited to this, and is applicable to metal strip materials other than those manufactured by rolling, as well as other strip materials such as paper, fabric, resin, etc., as long as the strip material performs a desired treatment. Not even. Further, a series of processing is performed by arranging five foil and strip strip processing apparatuses in parallel, but a series of processing may be performed by arranging a plurality of machines other than five in parallel. However, the processing may be performed independently. Furthermore, as the processing tank, an example in which the cross section is rectangular, the upper surface is open, and a lid is disposed on the upper surface to define a substantially sealed processing space inside, but any cross-sectional area is provided. The cover may not necessarily be provided. For example, the processing liquid may be stored in a processing tank with the upper surface open, and the strip material may be sequentially immersed in the processing liquid.

In the above-described embodiment, the processing apparatus for a foil and a strip having five stages of drive rollers is exemplified. However, the number of drive rollers does not necessarily have to be five, and There may be a plurality other than 5 or only one. In particular, when processing a strip material having a large thickness, it is possible to mix driving rollers and non-driving rollers. In the embodiment described above in the case where a plurality of rollers are provided inside the processing tank, these are arranged so that the heights thereof are different from each other.
A plurality of drive rollers may be arranged at the same height position. In this case, the roller does not necessarily need to be moved up and down. In addition, since a plurality of rollers are supported by a common unit frame, as described above, the disassembly work involved in maintenance and replacement of the rollers can be performed very easily, but it is not always necessary to use a common frame. There is no need to support. Furthermore, since drive rollers for applying a conveying force to the strip material are arranged at both ends of the processing tank,
That is, since the auxiliary roller is brought into contact with the driving roller at the most upstream side and the downstream side of the processing tank, the processing liquid used in the processing tank is mixed into the next processing tank by the squeezing action of both rollers. The situation can be prevented as much as possible. For example, in the case of the above-described embodiment, the contamination of the processing solution on the downstream side due to the mixing of the processing solution on the upstream side can be prevented as much as possible. It is not necessary to arrange drive rollers for applying a conveying force to both ends of the processing tank.

Further, in the above-described embodiment, the permanent magnets are arranged on both of the power transmission members facing each other, but the present invention is not limited to this. For example,
If it is possible to sufficiently transmit the rotational force to the other power transmission body by the magnetic force of the magnet arranged only on one power transmission body, the other power transmission body may be made of a strong material such as iron or nickel. It is sufficient to dispose only the magnetic material. Alternatively, an electromagnet may be provided instead of the permanent magnet, and a magnetic force may be applied between the two power transmission members only when transmitting a rotational force. Further, when a permanent magnet is applied, the power transmission body is configured to be able to change the mutual separation distance, and when an electromagnet is applied, the power transmission body is configured to be able to change the mutual separation distance, or in this case, In addition, by changing the magnetic force, it is possible to appropriately change the roll restraining force by the rotary actuator, and it is possible to perform control more similar to helper control.

[0044]

As described above, according to the present invention,
The magnetic force of the power transmission body is used to transmit the rotational force of the drive source disposed outside the processing tank to the roller disposed inside the processing tank. It is not necessary to provide a hole for exposing on the wall of the processing tank. Therefore, even with respect to the roller immersed in the processing liquid, the processing liquid can be rotationally driven without causing the leakage of the processing liquid to the outside, and until the start end of the strip material is wound by the winder. It is possible to improve productivity, for example, by efficiently performing the above operation.

In addition, since no holes are formed in the wall of the processing tank, no sealing means is required, and the rollers are physically separated from the driving source and the processing tank. Can be performed very easily.

Further, since the roller is driven to rotate while being physically separated from its driving source, the influence of mechanical loss and inertia force on the strip material can be minimized. However, even when a general-purpose electric motor or air motor is used as a drive source, there is no fear that harmful tension is applied to the strip material. As a result, the same effect as the helper control can be obtained without causing a significant increase in application cost. For example, even for a very thin strip material of about several μm, desired treatment can be performed without causing breakage. Can be applied.
