2. Description of the Related Art For example, in recent years, there has been known a catalyst device for purifying harmful components such as HC, CO and NOx in exhaust gas by disposing a purifying catalyst in an exhaust passage of an internal combustion engine such as an automobile. In this type of catalyst device, a metal honeycomb body is used as a catalyst carrier.

For example, as shown in FIG. 11, this metal honeycomb body is formed by stacking a flat foil 1 and a corrugated foil 2 of metal foil and winding them in a spiral shape to form a cylindrical shape as shown in FIG. Innumerable through holes 4o are formed in the axial direction, and are generally inserted into the casing 3 for use.

As a method for winding the flat foil 1 and the corrugated foil 2 of the metal foil in the case of manufacturing the metal honeycomb body 4, Japanese Patent Laid-Open No.
There is an invention described in JP-A-371234. In the present invention, a winding device for obtaining a metal honeycomb body 4 by superposing a flat foil 1 of a metal foil and a corrugated foil 2 and winding them is generally shown in FIG.
It is configured as shown in FIG. In FIG. 13, 5 is a winding shaft that is rotated by a drive device (not shown), and a pair of side clamps Ca and Cb are mounted on the winding shaft so that the distance a can be adjusted. Both end surfaces of the metal flat foil 1 and the metal corrugated foil 2 which are wound on the winding shaft 5 in a stacked manner can be pressure-supported.

As shown in FIG. 14, the winding shaft 5 of this winding device has a slit groove 5o through which the leading ends of the flat metal foil 1 and the corrugated metal foil 2 are inserted and locked. Three crimping rolls Ra, Rb, and Rc are arranged on the outside of 5 in parallel with the winding shaft 5 so as to be movable back and forth with respect to the winding shaft by the drive unit M, and the winding core portions (2 to 3). When forming the winding portion, it is possible to assist the rigidity of the winding shaft 5 and adjust the winding shape.

In this winding device, the tips of the metal flat foil 1 and the metal corrugated foil 2 carried in from the foil supply device (not shown) are overlapped and inserted into and locked in the slit groove 5o of the winding shaft 5, The three press rolls Ra, Rb, and Rc cooperate with the rotation of the take-up shaft to start the take-up, and after forming two to three turns to form the winding core, the three press rolls are retracted to make a pair. Of the side clamps Ca and Cb, the end faces of the flat metal foil 1 and the corrugated metal foil 2 are pressure-supported by the pressure-supporting faces of the center parts of the side clamps, and the ends are aligned. Then, the metal honeycomb body 4 can be manufactured.

When such a winding device is used, when the flat metal foil 1 and the metal corrugated foil 2 having a conventional level of thickness (50 to 100 μm) are superposed and wound into a honeycomb shape, a predetermined winding is automatically performed. It is possible to obtain a metal honeycomb body having a stable outer peripheral length and stable quality, and to improve the efficiency of the winding operation.

However, in recent years, with respect to a metal honeycomb body used as a catalyst carrier of a catalyst device, in order to improve catalyst efficiency, the thickness of the metal flat foil forming the honeycomb body and the metal foil used as a metal corrugated foil are further reduced. (30 to 40 μm) is increasing, and the rigidity of the flat foil and the corrugated foil is further reduced. Therefore, when winding to form the honeycomb body, there is a concern that a defective shape, breakage, or the like may occur. It is becoming larger, and it is hard to say that the present invention is completely safe as a winding method that does not cause such an inconvenient phenomenon.

That is, according to the present invention, when the flat metal foil and the corrugated foil are stacked and wound, the winding diameter is 3 by the winding shaft.
After winding up to 0-40mm, both ends are pressed and supported by the pressurizing pressure supporting surface formed in the center of the pair of side clamps, and are wound up. Can suppress the winding tightness by increasing the pressure supporting force, but when the foil is thin and the rigidity is small, the pressure supporting force cannot be increased, so that the winding resistance increases as the winding progresses, It is unavoidable that the winding tightness phenomenon occurs in the winding core portion and its vicinity. Therefore, the dimensions of the honeycomb body due to foil rupture or deformation of the foil shape,
There is a problem that it is difficult to stably manufacture a honeycomb body of good quality due to an inconvenient phenomenon such as a defective shape.

Flat foil and corrugated foil made of metal foil of 0 to 40 μm are stacked and wound up with a tension of 0.5 to 5 kgf / mm ² , and the diameter is 100 to 500 mm.
When manufacturing the metal honeycomb body, the pressure supporting force by the side clamps on the end faces of the metal honeycomb body in the winding process is dispersed to prevent the end crushing phenomenon of the metal honeycomb body and prevent the tightening of the winding.

Through the experiments, the inventors of the present invention have found that when a metal honeycomb body is manufactured by using a winding device equipped with a pair of side clamps, the crushing phenomenon of the end face and the winding tightening phenomenon are caused by a flat metal foil and a metal wave. Obtaining the knowledge that it is most likely to occur in the small diameter region of the process of stacking and winding the foils, at least, examining the means for suppressing the occurrence of the crushing phenomenon of the end face in this small diameter region, the winding tightening phenomenon, the present invention is effective The conclusion was reached.

In the first aspect of the present invention, the pressure supporting area of the end face of the honeycomb body is increased by the pair of side clamps in accordance with the increase of the winding diameter to disperse the pressure supporting force to the end face of the honeycomb body. By doing so, it is possible to secure the winding force with a relatively small pressure supporting force, and it is possible to prevent the end face of the honeycomb body from being crushed by the pressure supporting by the pair of side clamps. In addition, the pressing support area of the end face of the honeycomb body by the pair of side clamps is increased in accordance with the increase of the winding diameter, and the winding is performed while sufficiently securing the pressure support at each part. It is possible to prevent the occurrence of

When the pressure supporting area by the pair of side clamps is increased in accordance with the increase in the winding diameter, it is desirable to continuously increase it in accordance with the change in the winding diameter of the metal honeycomb body. However, the structure and mechanism that can do this are complicated and expensive, and considering the balance with the effect obtained, it is not always a good idea to continuously increase the pressure supporting area according to the change of the winding diameter. hard.

For example, it is highly practical to divide the side clamp into a plurality of parts in the radial direction and increase the pressure supporting area stepwise in units of the divided clamps. The number of radial divisions in this case is determined according to the diameter and length of the honeycomb body and the thickness of the metal foil, but the diameter is 100 to 500 mm and the length is 100 to 50.
When manufacturing a metal honeycomb body having a thickness of 0 mm and a metal foil thickness of 20 to 40 μm, 3 to 7 is sufficient. The pressure supporting area may be changed at the starting diameter, the intermediate diameter, the final diameter of each divided clamp, or stepwise or continuously.

The pressure supporting force by the pair of side clamps is usually 4 to 20 kgf / mm ² . If it is less than this, the winding force cannot be secured, and the tightening of the winding is likely to occur. Further, if it is more than this, there is a large possibility that the edge is crushed.

It is desirable that the winding tension is usually 0.5 to 5 kgf / mm ² . Below this, a honeycomb body having a sufficient and uniform density cannot be obtained. Further, if it is more than this, the deformation of the peak shape of the metal corrugated foil becomes remarkable, resulting in dimensional defects and shape defects, and there is a high possibility that the metal corrugated foil and the flat foil will break.

By satisfying each of the above conditions,

In the second invention, the pressure supporting force by at least one of the side clamps on the end face of the metal honeycomb body is continuously or stepwise increased according to the increase of the winding diameter, and the pressure supporting force per unit area is increased. By selecting the pressure supporting force so that the force supporting force per unit area against the end surface of the metal honeycomb body does not exceed the permissible range for preventing edge collapse, Can be prevented from being crushed. Further, since the end face of the metal honeycomb body is supported in a wide range with a pressure supporting force within a permissible range for winding, winding tightness can be prevented.

When the pressure supporting force by the pair of side clamps is increased in accordance with the increase in the winding diameter, it is desirable that the pressure supporting force is continuously increased in accordance with the change in the winding diameter of the metal honeycomb body. However, the structure and mechanism that can do this are complicated and expensive, and considering the balance with the effect to be obtained, it is not always a good idea to continuously increase the pressure supporting force according to the change in the winding diameter. hard.

For example, it is highly practical to divide the side clamp into a plurality of parts in the radial direction and increase the pressure supporting force stepwise in units of the divided clamps. The number of radial divisions in this case is the same as in the case of the first invention. The pressure supporting force may be changed at the starting diameter, the intermediate diameter, the final diameter of each split clamp, or stepwise or continuously. The pressure supporting force and the winding tension by the pair of side clamps are the same as in the case of the first invention.

By satisfying each of the above conditions,
The pressure supporting force by the side clamps on the end faces of the metal honeycomb body in the winding process is made uniform, and the end crushing phenomenon of the metal honeycomb body is prevented, and winding tightness, the flat metal foil, and the breaking of the metal corrugated foil are prevented, It is possible to stably secure the dimensional accuracy, shape characteristics, and structural characteristics of the obtained metal honeycomb body and stabilize the quality.

By using two driving devices, a connecting shaft is not required between the pair of side clamps, and the installation space for the winding core forming device, the carry-out device, the spot welding device, etc. can be efficiently arranged.

In the fifth aspect of the invention, the pair of side clamps can be independently rotated by separate driving devices, and the winding shaft can be rotated by a driving device different from the driving device for the side clamps. Since the side clamp and the take-up shaft can be independently rotated, the side clamp can be selectively rotated only when necessary, for example, for measures against walk. Also,

In the case of manufacturing a level honeycomb body, 3 to 7 is sufficient, and the radial dimension (width) of each of the divided pressurizing support portions may be the same, but as described above, from the small diameter side to the large diameter side. It is desirable to reduce the width.

1, 1, 2, and d3), the pressure supporting force per unit area by the pressure supporting surfaces of the small diameter pressure supporting portion 81, the medium diameter pressure supporting portion 82, and the large diameter supporting portion 83 against the end face of the metal honeycomb body 4 is allowable. It is effective to control the pressure supporting force against the side end face of the honeycomb body in each winding diameter region so as not to exceed the range, and to wind the honeycomb body while preventing the honeycomb body from being crushed.

A fourth example of the winding device for carrying out the first invention and the second invention of the present invention will be outlined with reference to FIGS. This embodiment is different from the first embodiment in that the side clamp 8b has a medium-diameter support portion 82 and a large-diameter support portion 8b.

It is possible to wind the metal honeycomb body while dispersing it to prevent the edge of the metal honeycomb body from being crushed.

Further, here, since the pressure supporting surfaces of the medium diameter support portion 82 and the large diameter support portion 83 are formed in the free rotation portions 822 and 832, they are free to be restrained by the rotation of the side clamp 8b. Since it can be rotated to the end, the end surface of the metal honeycomb body can be pressure-supported even during the winding operation, and wear of the pressure-supporting surface can be reduced.
