[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shaft supporting structure capable of reducing a winding load on a winding shaft when a metal flat foil and a metal corrugated foil are stacked and wound in a honeycomb shape to manufacture a metal honeycomb body. The present invention relates to a winding device for a metal honeycomb body having the same.

[0002]

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

This metal honeycomb body is formed, for example, as shown in FIG. 6, by laminating a flat foil 1 of metal foil and a corrugated foil 2 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 when manufacturing the metal honeycomb body 4, there is an invention described in Japanese Patent Application Laid-Open No. 4-371234 filed by the applicant of the present invention. In the present invention, a flat metal foil 1 and a corrugated foil 2 are used.
A winding device for obtaining the metal honeycomb body 4 by stacking and winding the above is generally configured as shown in FIGS. 8 and 9.

In FIG. 8, reference numeral 5 denotes a driving device (not shown).
A pair of side clamps Ca and Cb are mounted on the take-up shaft so as to be adjustable in space, and the flat metal foil is wound around the take-up shaft 5 between the pair of side clamps. 1 and both end surfaces of the metal corrugated foil 2 can be pressure-supported.

As shown in FIG. 9, the winding shaft 5 of this winding device has a slit groove 5o through which the tips of the flat metal foil 1 and the corrugated metal foil 2 are inserted and locked. 3 outside 5
The book pressure bonding rolls Ra, Rb, Rc are arranged in parallel with the winding shaft 5 so as to be able to move forward and backward with respect to the winding shaft by the drive unit M, and when forming the winding core portion (2 to 3 times winding portion). The rigidity of the take-up shaft can be assisted and the take-up shape can be adjusted.

In this winding device, the leading end portions of the flat metal foil 1 and the metal corrugated foil 2 supplied from a conveying device (not shown) are inserted and locked in the slit grooves 5o of the winding shaft 5 to wind them. Axis 5
The three crimping rolls cooperate with the rotation of the
After forming the core part by winding 2 to 3 rolls, the three pressure rolls are retracted, and the flat metal foil 1 and the metal corrugated foil 2 are pressed by the pressure supporting surfaces of the center parts of the pair of side clamps Ca and Cb. It is possible to manufacture the metal honeycomb body 4 by press-supporting the end faces to adjust the ends, and then winding the end faces while pressure-supporting the press-supporting faces at the central portions of the pair of side clamps.

The winding shaft 5 used in such a winding device, for example, as shown in FIG. 9, superposes the flat metal foil 1 and the metal corrugated foil 2 at the start of winding and inserts the tip end thereof. In order to minimize the diameter of the shaft hole formed in the center of the metal honeycomb body obtained by winding, the diameter of the winding shaft is as small as possible. In many cases (for example, 5 mm), if the winding load is increased, the winding shaft may be broken or bent, making it impossible to wind, smooth winding becomes difficult, and dimensional accuracy and shape accuracy May decrease, and it may be difficult to manufacture a metal honeycomb body with stable quality with high productivity.

When such a winding device is used, when a metal flat foil having a thickness of 50 to 100 μm and a width of 30 to 100 mm, which is a conventional level, and the metal corrugated foil 2 are overlapped and wound into a honeycomb shape, a predetermined winding is automatically performed. It is possible to obtain a metal honeycomb body of stable quality with a long circumference of the take-up outer periphery, and to improve the efficiency of the winding operation.

However, in recent years, a honeycomb body is formed such as a diesel carrier, a cogeneration carrier, and a carrier for double-size cutting for the purpose of reducing the manufacturing cost by cutting one carrier into two or three. There is an increasing demand for further lengthening (100 to 500 mm) of metal flat foil and metal corrugated foil. Since the width of the metal flat foil and metal corrugated foil becomes wider and the rigidity further increases, this At the time of winding to wind up to form a metal honeycomb body, breakage of the winding shaft,
There is a growing concern about deterioration of the winding quality due to twisting, and it is said that the winding apparatus (method) according to the present invention is completely safe as a winding apparatus (method) that does not cause such an inconvenient phenomenon. Hard to say.

That is, according to the present invention, when the metal flat foil and the metal corrugated foil are stacked and wound, as shown in FIG. 9, three pressure bonding rolls Ra, Rb are provided outside the winding shaft 5. R
c is arranged so as to be movable back and forth with respect to the winding shaft, and the winding core portion is formed while being supported under pressure by these three pressure bonding rolls. Must be accurately maintained, and the reaction force must be evenly distributed and maintained among the three pressure rolls.

Therefore, the time and expense for adjusting and maintaining the crimp roll are required. Further, in the present invention, three crimping rolls are used, each of which is required to be equipped with a cylinder mechanism for crimping support, a crimping force control structure such as a pneumatic pressure supply control device, facility cost, There is a problem that the operating cost becomes high and the manufacturing cost of the metal honeycomb body becomes high.

[0013]

DISCLOSURE OF THE INVENTION The present invention is a winding device for manufacturing a winding metal honeycomb body by stacking a flat metal foil and a metal corrugated foil on a winding shaft to easily form a winding core portion. Damage to the take-up shaft by compensating for the shaft rigidity of the take-up shaft by inexpensive means,
The present invention provides a winding device for a metal honeycomb body, which can prevent the occurrence of bending, and can highly productively manufacture a metal honeycomb body having a high core shape accuracy and stable quality.

[0014]

SUMMARY OF THE INVENTION The present invention is directed to a winding shaft for winding a metal flat foil and a metal corrugated foil on top of each other, and a pair for pressing and supporting side edges of the metal flat foil and the metal corrugated foil during winding. In a winding device for a metal honeycomb body equipped with a side clamp, the two legs of a Y-shaped shaft support are arranged so as to be movable back and forth in the direction orthogonal to the winding shaft, and a flat metal foil is attached to the winding shaft. When the tip of the metal corrugated foil is locked to form the winding core, the winding shaft is clamped between both legs of the Y-shaped shaft support, and the winding load on the winding shaft is reduced. A winding device for a metal honeycomb body, which is configured to be wound up while being wound.

In the present invention, when a thin metal flat foil and a metal corrugated foil are superposed on each other by using a winding device to manufacture a rolled metal honeycomb body, the flat metal foil is placed in the slit groove of the winding shaft 5. When inserting the tip of the metal corrugated foil and rotating the winding shaft to form the winding core or the honeycomb body,
Winding with a tension of 0.5 kgf / mm ² , the diameter is 10-30 mm
The core portion is formed, the side end surface is pressed and supported by a pair of side clamps, and the winding tension is set to 0.6 to 5 kgf / mm ² , and the metal core is manufactured. When forming the portion, since the winding is carried out with a relatively large tension, a large load is applied to the winding shaft 5. Therefore, in this process, the Y-shaped member arranged so as to be movable back and forth with respect to the winding shaft is used. The winding shaft can be held by the holding surface between both legs of the shaft support, the winding load on the winding shaft can be reduced, and the winding shape accuracy can be stably ensured.

Here, the Y-shaped shaft support for supporting the winding shaft used is relatively inexpensive by processing a relatively inexpensive material such as general structural steel and joining it by a joining means such as welding. The shape of the winding shaft holding portion between both legs is V
It is formed in a letter shape, a U shape, or a shape similar to these, and the included angle depends on the range of the diameter of the winding shaft.
If it is 0 degree, the winding shaft can be supported sufficiently stably.

When the sandwiching surfaces of both legs of the sandwiching portion are formed symmetrically, the outermost sandwiching point on this sandwiching surface is, for example, both sandwiching points and the winding center point at the maximum winding diameter of the winding core. It is preferable to arrange them so that the included angle connecting with and becomes 45 degrees or more. It is sufficient that the sandwiching points are 2 to 3 points. It is also possible to hold the clamping surface in surface contact with the peripheral surface of the take-up shaft, but the contact resistance increases.
There is a risk that smooth winding may not be possible. Further, both legs of the sandwiching portion may be configured to be openable and closable so that the opening thereof can be adjusted according to the winding diameter. In order to reduce the contact resistance on the sandwiching surface, the sandwiching surface has a friction resistance. Mitigation materials, such as Teflon material, may be provided.

The holding portion of the Y-shaped shaft support is
In order to ensure stable shape accuracy of the winding core, it is preferable to form so as to support the entire width of the flat metal foil and the corrugated metal foil, but a plurality of them may be arranged side by side in the axial direction of the winding shaft. It may be sandwiched intermittently.

The supporting force of the holding portion of the Y-shaped shaft support member is set to 1 to 3 kg per cm of the metal foil width in order to supplement the winding shaft rigidity and ensure the winding shape accuracy. In addition, it is also possible to further enhance the shaft supporting function by providing a pressure roller on the opposite side of the Y-shaped shaft support body with the winding shaft interposed therebetween. By doing so, especially when forming the winding core portion, by the shaft support,
In addition to supplementing the axial rigidity of the winding shaft, the shape accuracy of the winding core portion can be ensured, and the dimensional accuracy, shape accuracy, etc. of the obtained metal honeycomb body can be stably ensured and the quality can be stabilized.

A pair of side clamps 6A and 6B mounted so that the distance between them can be adjusted,
In the vicinity of the winding shaft 5, there is provided a Y-shaped shaft support 7 which is movable back and forth in the direction orthogonal to the winding shaft.

As shown in FIG. 2, this Y-shaped shaft support has a V-shaped holding portion 7a for holding the winding shaft 5 from the direction orthogonal thereto, and the support rod 7b of the holding portion is supported. It is attached to a gantry 8 via a pneumatic cylinder 9, and the holding portion 7 a is movable back and forth with respect to the winding shaft 5. Here, the width a of the holding portion 7a of the shaft support is set to a width close to the width b of the metal flat foil 1 and the metal corrugated foil 2 wound on the winding shaft 5, and the winding shaft 5 and the winding shaft 5 are wound in the width region. It is configured so that the core portion 4x can be held.

As described above, according to the present invention, a simple Y-shaped shaft support 7 is provided outside the winding shaft 5 in place of the conventional pressure-bonding roll so that the Y-shaped shaft support 7 can be moved back and forth. Part 4x
Since the winding shaft (and the winding core of the flat metal foil and the corrugated metal foil) can be sandwiched at two points by the V-shaped sandwiching portion 7a when forming the sheet, it is more than the conventional support by the pressure roller. Thus, the winding shaft (and the winding core portion of the metal flat foil and the metal corrugated foil) can be easily and stably supported.

When the flat metal foil and the corrugated metal foil are thus laminated to manufacture a rolled-up metal honeycomb body, the flat metal foil 1 and the corrugated metal foil 2 are placed in the slit grooves 5o of the winding shaft 5. Insert the tip of the metal flat foil 1 and the metal corrugated foil 2 between the pair of side clamps 6A and 6B, rotate the winding shaft 5 and support the clamping surface of the clamping portion 7a of the Y-shaped shaft support 7. After supporting the winding shaft 5 (and the winding core portion of the metal flat foil and the metal corrugated foil) by force, the winding core portion 4x is wound 2 to 3 times, and then once.
The shaft support 7 is retracted and wound up until the winding diameter becomes 10 to 30 mm, then both ends are pressure-supported by side clamps, and subsequently the winding is performed up to a predetermined winding diameter, and finally the metal honeycomb obtained. Both ends of the body are pressed by a pair of side clamps to trim both end surfaces to produce a product.

In this way, when forming the winding core portion, the rigidity of the winding shaft is supplemented to improve the shaft life, and the shape accuracy and winding density of the winding core portion in the metal honeycomb body can be stably ensured. It is possible to stabilize quality such as dimensional accuracy, shape characteristics, and structural characteristics of the entire honeycomb body.

The present invention is not limited to the above embodiment. For example, regarding the structure (shape) of the winding shaft and the pair of side clamps and the drive mechanism, the shaft support, the structure (shape) of the pressure bonding roll, the drive mechanism, the arrangement, the supply direction of the metal flat foil and the metal corrugated foil, and the like, It is changed within the range satisfying the claims according to the thickness of the metal foil, the diameter of the metal honeycomb body, and the like.
