In addition, as shown to FIG. 17, FIG. 18, although it is the state which pressed the cylinder member holder 153 of the cylinder support means 132, it is not shown.
In the fourth step of winding, the central portion 26 of the band plate (corrugated plate material) 23 is sandwiched by the rotation clamping shaft 167, and the rotation clamping shaft 167 is rotated to wind the band plate (corrugated plate material) 23. (C-axis direction) By winding the band plate (corrugated plate material) 23 as indicated by the arrow c1, the wound band plate (corrugated plate material) 23 is directed from the outside toward the rotation axis M. Press as indicated by arrows c2 and c2, and wind around a substantially cylindrical shape.

  Specifically, when the pneumatic cylinder 77 of the pressing roller unit 38 is operated based on the information returned to the origin of the second bend unit 37 and the information of the control device, the buffer units 83 and 83 slide in a synchronized state ( And press the corrugated plate material 23... Based on the information on the predetermined position of the pressing roller means 38, the winding rotation means 35 starts operating.

15 rotates together with the rod 166 by the electric motor 164 of the winding rotation means 35, and the corrugated plate material 23.
As the winding and rotating means 35 winds the corrugated plate material 23..., The pressing roller means 38 slides in accordance with the remaining length of the corrugated plate material 23. ), The rest of the corrugated plate material 23 is supported from the outside, and the rotation of the remaining portions of the corrugated plate material 23 is continuously regulated (see FIG. 21).

  In this way, in the fourth step of winding, the band plate (corrugated plate material) is formed by sandwiching and winding the central portion 26 of the strip plate (corrugated plate material) 23 with the rotary clamping shaft 167 (C-axis direction). 23 is wound as indicated by an arrow c1, and the wound strip (corrugated plate material) 23 is pressed from the outside toward the rotation axis M as indicated by arrows c2 and c2, and is wound in a substantially cylindrical shape. When winding the strip (corrugated plate material) 23, it is difficult to loosen, and the strip (corrugated plate material) 23 can be wound tightly.

  Since the metal honeycomb catalyst carrier assembling apparatus 31 is provided with the pressing roller means 38, when the band plate (corrugated plate material) 23 is wound, the pressing roller means 38 forms the band plate (corrugated plate material) 23. The tension can be applied and the remaining portion can be wound tightly in connection with the portion where the bending radius r1 (see FIG. 1) at the beginning of winding is reduced. As a result, it is not necessary to directly pull the strip (corrugated plate material) 23 in the longitudinal direction, the structure for tight winding is simplified, and as a result, the structure of the metal honeycomb catalyst carrier assembling device 31 is simplified. Become.

  When the winding rotation means 35 finishes winding the corrugated plate material 23..., The mold means 39 is slid (in the directions of the arrows c3 and c3) and the fifth step of forming is performed.

  The timing at which the mold means 39 is activated is arbitrary. For example, the operator may operate a button, or may be based on information on the winding rotation means 35 or information on the pressing roller means 38.

FIG. 21 is a first explanatory view of a forming step performed by the method for assembling the metal honeycomb catalyst carrier of the present invention.
In the fifth step of forming, the die means 39 is slid (in the direction of arrows c3 and c3) so that the wound one (primary winding honeycomb) 191 becomes a cylindrical shape with a predetermined outer diameter on the spot (FIG. 23). reference).
The outer diameter of the wound one (primary winding honeycomb) 191 is D1. The outer diameter D1 is an average value, and D1> 2 × rm (see FIG. 12).

  As already described in the fifth step of forming, the pressing roller means 38 continues to slide (in the directions of the arrows c2 and c2) corresponding to the remaining length of the corrugated plate material 23. When 35 finishes winding the corrugated plate material 23..., The one wound with the first movable mold 123 and the second movable mold 124 (primary wound honeycomb) 191 is gripped. At that time, the first movable mold 123 and the second movable mold 124 are temporarily stopped in a state where a slight gap is formed between the support plates 91 and 91 of the pressing roller means 38 and the roller main bodies 92 and 92.

FIG. 22 is a second explanatory view of a forming step performed by the method for assembling the metal honeycomb catalyst carrier of the present invention.
Subsequently, the buffer means 83 of the pressing roller means 38 slides toward the origin (in the direction of arrows c4 and c4), and the first movable mold 123 and the second movable mold 124 are synchronized at the moment when the buffer means 83 comes out of the mold 101. The mold 101 is closed by moving forward (sliding in the directions of arrows c5 and c5).

23 (a) and 23 (b) are explanatory views of a molding process to a process of inserting into a cylindrical member performed by the assembling method of the present invention. (A) shows the process to shape | mold, (b) shows the process inserted in a cylinder member.
(A): In the forming step, the die 101 is closed and wound (primary winding honeycomb) 191 is applied with a surface pressure as indicated by an arrow c6. = 2 × rm). As a result, the wound honeycomb carrier 12 is obtained.

  “On the spot” means a state in which a wound around the rotary clamping shaft 167 (primary winding honeycomb) 191 is wound. Further, a state (a primary winding honeycomb) 191 wound between the table 95 of the mold means 39 and the pressing portion 141 of the honeycomb pressing means 131 is sandwiched.

  In this way, in the forming step, the mold means 39 is slid (arrows c3 and c3) so that the wound one (primary winding honeycomb) 191 becomes a cylindrical shape having a predetermined outer diameter Dp (Dp = 2 × rm) on the spot. c3), the wound honeycomb carrier 12 having a predetermined outer diameter Dp can be obtained. In the next step (sixth step), the wound honeycomb carrier 12 is wound without interfering with the cylindrical member 13 (the wound honeycomb carrier 12). ) Can be inserted.

  Subsequently, based on the information on the mold closing of the mold 101, the honeycomb extrusion inserting means 34 starts its operation and the sixth step of inserting starts.

(B): In the sixth step of insertion, the wound honeycomb carrier 12 obtained by molding is extruded and inserted into the cylindrical member 13 connected to the mold 101.
Specifically, when the electric motor 177 of the honeycomb push-out inserting means 34 shown in FIG. 15 is operated, the nut portion 181 of the screw mechanism 178 moves up along the slide guide 171 (in the direction of the arrow c7). While being lifted (slid), the wound honeycomb carrier 12 is pushed out, and at the same time, the wound honeycomb carrier 12 is inserted into the cylindrical member 13 using the mold 101 as a guide.

At that time, since the push rod 137 rises at the same speed as the push hollow shaft 174 rises, the wound honeycomb carrier 12 is released from the die 101 and enters the cylindrical member 13.
The wound honeycomb carrier 12 that has entered the cylindrical member 13 is spring-backed and slightly larger in diameter than the outer diameter Dp, and presses the inner surface of the cylindrical member 13, so that it is in an integrally fixed state.
Finally, the cylindrical member 13 fitted with the wound honeycomb carrier 12 is taken out, and one cycle is completed. Subsequently, the second cycle is started as shown in FIG. In addition, welding is performed by another process and another apparatus.

  Although the method and apparatus for assembling the metal honeycomb catalyst carrier of the present invention are applied to the honeycomb structure that holds the catalyst in the embodiment, it can also be applied to a honeycomb structure that is used other than holding the catalyst.

  The method and apparatus for assembling a metal honeycomb catalyst carrier of the present invention are suitable for a honeycomb structure that holds a catalyst used for exhaust gas purification.
