A transfer gear for transferring the brazing material to the top of the sheet, slurry supply means for supplying slurry-like brazing material to the transfer gear, a gear-shaped feed gear meshing with the corrugated plate, and drive means for driving the feed gear; The feed gear is arranged on at least one of the upstream side and the downstream side along the moving direction of the corrugated plate.

  The invention according to claim 2 is characterized in that a pressing gear for pressing the corrugated plate is provided between the transfer gear and the feed gear at a position where the transfer gear and the feed gear mesh with each other.

  In the invention according to claim 3, the transfer gear includes a first transfer gear that applies a brazing material to the outer side surface of the corrugated plate, and a second transfer gear that applies a brazing material to the inner side surface of the corrugated plate. The transfer gear and the second transfer gear are characterized by being arranged independently without directly meshing with each other.

  According to a fourth aspect of the present invention, the first transfer gear and the second transfer gear are arranged in the axial direction of the first transfer gear so that the brazing material application position differs between one surface of the corrugated plate and the other surface of the corrugated plate. Alternatively, the second transfer gear is offset in the axial direction.

And a feed gear for feeding the plate.

  Conventionally, the transfer gear has a slurry transfer function for transferring the slurry brazing material to the top of the corrugated sheet and a corrugated sheet feed function for feeding the corrugated sheet to the winding means. In order for the transfer gear to have both the slurry transfer function and the corrugated sheet feed function, it is necessary to increase the size of the transfer gear module.

  When the thickness of the corrugated sheet is reduced and the transfer gear module is large, the space at the tooth bottom of the transfer gear becomes large, and the slurry brazing material is accommodated in this space. Therefore, the amount of slurry brazing material transferred to the corrugated plate could not be reduced.

  In this regard, in the present invention, a transfer gear for transferring the slurry-like brazing material and a feed gear for driving the corrugated plate and feeding it to the winding means are provided separately from the transfer gear. Since there is no need to drive and feed the corrugated plate with the transfer gear, the transfer gear module can be made smaller.

If the module of the transfer gear is reduced, the space of the tooth bottom of the transfer gear is reduced, and the amount of slurry-like brazing material accommodated in this space is reduced. If the amount of slurry brazing material is reduced, the amount of slurry transferred can be reduced.
Moreover, since the feed gear which drives the corrugated plate and sends it to the winding means is provided separately, the corrugated plate can be driven smoothly.

The corrugated plate passes through the meshing portion of the transfer gear and the holding gear. Therefore, the corrugated plate can be brought into close contact with the transfer gear.

  In addition, even when the corrugated sheet is thin and the corrugated sheet is easily extended, the corrugated sheet is not easily detached from the transfer gear because the pressing gear is provided. If it becomes difficult for the corrugated sheet to come off the transfer gear, the brazing material can be accurately transferred to a predetermined position of the corrugated sheet.

In the invention according to claim 3, the first transfer gear and the second transfer gear are arranged independently without meshing with each other.
If the first transfer gear and the second transfer gear are arranged so as to be separated from each other in this manner, it is possible to improve the maintainability such as easy checking of the slurry outlets opened at the tooth bottoms of the respective gears.

In the invention according to claim 4, the first transfer gear and the second transfer gear are offset in the axial direction of the first transfer gear or the second transfer gear so that the brazing material transfer position is different.
If the first transfer gear and the second transfer gear are offset in the axial direction so that the brazing material transfer positions are different, the brazing material can be transferred in a staggered manner to the top portions provided on both surfaces of the corrugated plate.

In the invention according to claim 5, when the transfer gear makes one rotation, the gear groove includes a groove that meshes with the top of the corrugated plate and a groove that does not mesh with the top of the corrugated plate.
Even when the corrugated sheet is thinned, the corrugated sheet is extended, and the top of the corrugated sheet is temporarily removed from the transfer gear, causing a phase shift in the meshing position, the brazing material in all the gear grooves Therefore, there is no concern that the transfer leakage of the brazing material will occur.

In the invention according to claim 6, the pressing gear is disposed in front of and behind each of the first transfer gear and the second transfer gear.
The degree of adhesion between the corrugated sheet and the transfer gear is increased immediately before the brazing material is transferred to one surface of the corrugated sheet, and the degree of adhesion between the corrugated sheet and the transfer gear is increased immediately after the brazing material is transferred.
Since the degree of adhesion between the corrugated sheet and the transfer gear is increased before and after the brazing material is transferred to one surface of the corrugated sheet, the brazing material can be transferred to a more accurate position.

  In the invention according to claim 7, the transfer gear and the feed gear are offset in the axial direction so that the contact surface with the corrugated plate is different. Even when the feed gear is arranged on the downstream side of the transfer gear, there is no fear that the transfer surface transferred to the corrugated plate is damaged.

Hereinafter, the structure and operation of the second transfer device will be described in detail with reference to FIGS.
As shown in FIG. 4, the second transfer device 32 includes a first feed gear 43 having a gear shape that meshes with the corrugated plate from the left to the right along the moving direction of the corrugated plate 22. A first pressing gear 47 is disposed downstream of the first pressing gear 47, a second transfer gear 42 is disposed downstream of the first pressing gear 47, and a second pressing gear 48 is disposed downstream of the second transfer gear 42. A gear-shaped second feed gear 44 that meshes with the corrugated plate 22 is disposed downstream of the second pressing gear 48. The first feed gear 43 and the second feed gear 44 are each driven by driving means (FIG. 3, reference numerals 51 and 52).

  That is, the first pressing gear 47 and the second pressing gear 48 that constitute the pressing gear 46 are arranged on the upstream side and the downstream side of the first transfer gear 41 along the moving direction of the corrugated plate 22, respectively. The second transfer gear 42 is disposed upstream and downstream.

  The transfer gear 40 is located between the first feed gear 43 and the second feed gear 44 arranged on the upstream side and the downstream side along the moving direction of the corrugated plate 22 fed by the first feed gear 43 and the second feed gear 44. And a module obtained by dividing the modules of the first feed gear 43 and the second feed gear 44 by an integer of 2 or more. Slurry supply means 61 for supplying a slurry brazing material to the transfer gear 40 is attached to the transfer gear 40.

  In this embodiment, the feed gear is provided on the upstream side and the downstream side of the transfer gear. However, the feed gear may be provided only on the upstream side of the transfer gear as in the first transfer device described above. Alternatively, the feed gear may be provided only on the downstream side of the transfer gear.

  Between the second transfer gear 42 and the first feed gear 43, a first pressing gear 47 that presses the corrugated plate 22 is provided at a position where the second transfer gear 42 and the first feed gear 43 are engaged. Similarly, a second pressing gear 48 is provided between the second transfer gear 42 and the second feed gear 44 to press the corrugated plate 22 at a position where the second transfer gear 42 and the second feed gear 44 are engaged with each other. .

The holding gear 46 is disposed on the upstream side and the downstream side of the first transfer gear 41 along the moving direction of the corrugated plate 22 and on the upstream side and the downstream side of the second transfer gear 42.
The first transfer device 31 is different from the second transfer device in that the corrugated plate flows in the opposite direction, so that the direction of the device is different. There is no significant difference except that the positions of are different and the point where the second feed gear is omitted.
In the following description, the first transfer gear 41 and the second transfer gear 42 having the same structure are collectively referred to as a transfer gear 40.

Next, the pitch of the feed gear and the pitch of the transfer gear are compared.
FIG. 5A shows the feed gear 43 and FIG. 5B shows the transfer gear 40. When the pitch of the feed gear 43 is P, the pitch of the transfer gear 40 is set to be P / 4. Returning to FIG. 4, the corrugated plate meshes with each tooth of the feed gear 46.

Next, a state in which the corrugated plate is engaged with and closely attached to the holding gear will be described.
As shown in FIG. 6, the corrugated plate top 75 is aligned with the tooth tip 67 of the pressing gear 46, and the other apex 76 of the corrugated plate is aligned with the tooth bottom 77 of the pressing gear 46. 22 are engaged.

Next, a state where the brazing material filled in the transfer gear is transferred to the top of the corrugated plate will be described.
As shown in FIG. 7, the corrugated plate 22 is in close contact with the tooth surface of the pressing gear 46. The transfer gear 40 driven by the transfer gear driving means (FIG. 3, reference numeral 56) rotates, and the pressing gear 46 rotates with the rotation of the transfer gear 40, and the gear of the transfer gear 40 is placed on the top 75 of the corrugated plate. The brazing material 62 filled in the groove 69 is transferred.
When the transfer gear 40 makes one rotation, the gear groove 69 includes a groove (gear groove 81) that meshes with the top portion 76 of the corrugated plate and a groove (gear groove 82) that does not mesh with the top portion 76 of the corrugated plate.
In the next rotation, the top part 76 of the corrugated sheet meshes with the groove that did not mesh with the top part 76 of the corrugated sheet at the first rotation. That is, the groove that meshes with the top portion 76 of the corrugated sheet is shifted every rotation.

  Referring also to FIG. 4, a pressing gear 46 that meshes with the transfer gear 40 and the feed gear 45 is provided between the transfer gear 40 and the feed gear 45. The corrugated plate 22 passes through the meshing portion of the transfer gear 40 and the holding gear 46. Therefore, the corrugated plate 22 can be brought into close contact with the transfer gear 40.

  In addition, even when the corrugated sheet 22 is thin and the corrugated sheet is easy to extend, the retainer gear 46 is provided, so that the corrugated sheet 22 is in close contact with the retainer gear 46, and the corrugated sheet 22 is separated from the transfer gear 40. It becomes difficult to come off. If it becomes difficult for the corrugated plate 22 to be detached from the transfer gear 40, the brazing material 62 can be accurately transferred to a predetermined position of the corrugated plate 22.

Next, the operation of the honeycomb structure manufacturing apparatus described above will be described.
As shown in FIG. 8A, in the embodiment, the manufacturing apparatus 20 includes a transfer gear 40 that transfers the brazing material 62 to the corrugated plate 22. Referring also to FIG. 4, the manufacturing apparatus 20 includes a feed gear that is disposed on the upstream side and the downstream side of the transfer gear 40 along the moving direction of the corrugated plate 22 and feeds the corrugated plate 22.

  As shown in FIG. 8B, in the comparative example, the manufacturing apparatus 20B includes transfer gears 40B and 40B arranged so as to mesh with both surfaces of the brazing material. The transfer gears 40B and 40B have both a slurry transfer function for transferring the slurry brazing material to the top of the corrugated plate 22, and a corrugated plate feed function for feeding the corrugated plate 22 to the winding means. In order to make the transfer gears 40B and 40B have both the slurry transfer function and the corrugated sheet feed function, it is necessary to enlarge the modules of the transfer gears 40B and 40B.

  When the thickness of the corrugated plate 22 is reduced, if the modules of the transfer gears 40B and 40B are large, the space at the bottom of the transfer gears 40B and 40B becomes large, and the slurry brazing material 62 is accommodated in this space. . Therefore, the amount of the slurry-like brazing material 62 transferred to the corrugated sheet cannot be reduced.

  Referring to FIGS. 8A and 4 together, in the present invention, the transfer gear 40 for transferring the slurry-like brazing material 62 and the corrugated plate 22 are driven separately from the transfer gear 40 to wind the winding means. A feed gear 45 to be fed to is provided separately. Since there is no need to drive and send the corrugated plate 22 with the transfer gear 40, the module of the transfer gear 40 can be made smaller.

If the module of the transfer gear 40 is reduced, the space of the tooth bottom of the transfer gear 40 is reduced, and the amount of the slurry-like brazing material 62 accommodated in this space is reduced. If the amount of the slurry-like brazing material 62 is reduced, the transfer amount of the brazing material can be reduced.
Further, since the feeding gear 45 that drives the corrugated plate 22 and sends it to the winding means (winding means) is provided separately, the corrugated sheet 22 can be smoothly driven and sent to the winding means.

  In addition, the module of the transfer gear 40 is obtained by dividing the module of the feed gear 45 by an integer of 2 or more. In this embodiment, the transfer gear 40 and the feed gear 45 have the same pitch circle diameter, and the number of teeth of the transfer gear 40 is four times the number of teeth of the feed gear 45. It becomes 1/4 of the module of the feed gear 45, and the space of the tooth base becomes small. Since the module of the transfer gear 45 is made smaller while the module of the feed gear 45 is made larger, the corrugated sheet 22 can be reliably fed.

Next, the amount of the brazing material transferred by the apparatus according to the present invention is compared with the amount of the brazing material transferred by the apparatus according to the comparative example.
As shown in FIG. 9A, in the embodiment, since the module of the transfer gear 40 is made smaller than the module of the feed gear 45, the transfer amount of the brazing material 62 can be reduced.

As shown in FIG. 9B, in the comparative example, since the transfer gear was provided with a feeding function in addition to the brazing material transfer function, there was a restriction on reducing the size of the transfer gear 40 module. If the module of the transfer gear 40 is not reduced, the space of the tooth bottom cannot be reduced, and the amount of the brazing material 62B filled in the tooth bottom increases.
Returning to FIG. 9A, in the present invention, since the transfer amount of the brazing material 62 can be reduced, the transfer onto the corrugated plate 22 can be performed uniformly and speedily.

The first transfer gear 41 and the second transfer gear 42 that transfer the brazing material to one surface and the other surface of the corrugated plate are arranged independently without being engaged with each other.
If the first transfer gear 41 and the second transfer gear 42 are arranged so as to be separated from each other in this manner, it is easy to check the slurry outlets opened in the tooth bottoms of the respective gears, thereby improving maintenance. it can.

2 and 3, the first transfer tooth surface 41a, the second transfer tooth surface 41b provided on the first transfer gear 41, the third transfer tooth surface 42a provided on the second transfer gear 42, and the fourth transfer tooth. The surface 42b is offset in the axial direction of the first transfer gear or the axial direction of the second transfer gear so that the brazing material transfer position is different.
If the first transfer gear 41 and the second transfer gear 42 are offset in the axial direction so that the brazing material transfer positions are different, the brazing material is transferred in a staggered manner to the top portions provided on both surfaces of the corrugated plate 22. Can do.

  A holding gear 46 is disposed in front of and behind each of the first transfer gears 41 provided in the first transfer device 31. For this reason, since the adhesiveness between the corrugated sheet 22 and the transfer gear 40 is increased before and after the brazing material is transferred to one surface 22a of the corrugated sheet, the brazing material can be transferred to a more accurate position.

Returning to FIG. 4, the pressing gears 46 are disposed in front of and behind each of the second transfer gears 42.
Immediately before the brazing material (FIG. 8 (a), reference numeral 62) is transferred to the other surface 22b of the corrugated sheet, the degree of adhesion between the corrugated sheet 22 and the transfer gear 40 is increased. The degree of adhesion between the plate 22 and the transfer gear 40 is increased.
Since the degree of adhesion between the corrugated sheet 22 and the transfer gear 40 is increased before and after the brazing material is transferred to the other surface 22b of the corrugated sheet, the brazing material 62 can be transferred to a more accurate position.

In claim 1, the holding gear can be omitted.
In claim 2, the first transfer gear and the second transfer gear may be arranged so as to mesh with each other.

  According to a third aspect of the present invention, the one transfer gear and the second transfer gear have a brazing material transfer position between one surface of the corrugated plate and the other surface of the corrugated plate in the axial direction of the first transfer gear or the second transfer gear. It does not matter that they are the same in the axial direction.
