The base means 30 and its annular groove 31 are made of metal, and the inner peripheral surface of the annular groove 31 is substantially equal to the outer periphery of the annular friction material 10 </ b> A formed by a plurality of fan-shaped friction materials 10. The upper inner side of the annular groove 31 is substantially the same as the inner diameter of the annular friction material 10A, and is substantially equal to the inner diameter of the annular friction material 10A on the inner side of the bottom surface.

That is, as shown in FIGS. 1 to 3, the inner peripheral wall 31e of the disk portion 35, which is the central protrusion of the base means 30, is formed such that the upper end portions 31a passing through the center are mutually connected and the lower end portions 31b passing the center are also connected. The distance between the end portions passing through the center increases in proportion to the depth of the annular groove 31. Further, the outer peripheral wall 31 d of the annular groove 31 of the outer peripheral guide portion 32 of the base means 30 is a smooth surface and is formed perpendicular to the bottom surface 31 c of the annular groove 31. The outer periphery guide part 32 of the present embodiment is a separate member from the disk part 35 and does not rotate integrally with the disk part 35, and the outer periphery guide part 32 is fixed to the other member, It is unrelated to the rotation of. In addition, by making the outer periphery guide part 32 into a stop state with respect to the rotation of the disk portion 35, the fan-shaped friction material 10 placed on the bottom surface 31c of the annular groove 31 receives a contact resistance slightly resisting the rotation.
The lower surface side of the base means 30 obtains a controlled rotational force of a power source (not shown) and is rotatably fixed to the rotary shaft 33 with bolts 34.

It can be a moving means for moving 10A.

An air passage 54 and a suction head 55 (not shown) are formed inside the annular lower part 51, and the suction is performed by the suction head 55 at the lower end of the annular lower part 51. Therefore, the air passage 54 is also piped inside or outside the frame 52. The fan-shaped friction material 10 sucked by the suction head 55 at the lower end of the annular lower portion 51 is in an aligned state as the annular friction material 10A, so that the middle and the end of the fan-shaped friction material 10 are sucked. Yes.
In addition, even if the conveyance surface 65 of the supply path 60 is arrange | positioned in the position higher than the bottom face 31c of the annular groove 31, and it is the structure which always attracts | sucks the middle and the edge part of the fan-shaped friction material 10, There is no hindrance to the operation of making the plurality of fan-shaped friction materials 10 into the annular annular friction material 10A.

Extruding means 63 is disposed in the supply path 60, and the fan-shaped friction material 10 is guided to the bottom surface 31 c of the single annular groove 31 by one reciprocation of the extruding means 63. That is, when the pushing means 63 presses the fan-shaped friction material 10, one of the fan-shaped friction materials 10 is guided to the bottom surface 31c of the annular groove 31, and when the pushing means 63 returns, one fan-shaped friction material 10 is present there.

Since the fan-shaped friction material 10 is regulated by both side walls of the supply path 60, the intermediate line in the circumferential direction of the fan-shaped friction material 10 is moved in the diameter direction passing through the center thereof.
Note that the fan-shaped friction material 10 falls into the annular groove 31 from the supply port of the supply path 60 at the same time that the inner diameter side of the fan-shaped friction material 10 abuts on the inner peripheral wall 31e. The material 10 can be moved downward and guided by a pressing rod whose outer shape is slightly reduced. Therefore, the fan-shaped friction material 10 is sequentially sent out so that the center line corresponding to the diameter thereof is positioned in the delivery direction of the pushing means 63. The supply of the fan-shaped friction material 10 to the supply path 60 is performed by a supply device (not shown).

Next, the operation of the lockup clutch friction plate assembling apparatus of the first embodiment of the present invention configured as described above will be described.
The fan-shaped friction material 10 punched out at another location (not shown) sequentially feeds the supply path 60 shown in FIG. 1 toward the base means 30 and the center of the disk portion 35.
The fan-shaped friction material 10 is sequentially conveyed so that a center line having a diameter thereof is positioned in a direction in which the fan-shaped friction material 10 is sent out by the pushing means 63. The fan-shaped friction material 10 is sent out by the pushing means 63, and the fan-shaped friction material 10 is supplied to the supply path 60 by a supply device (not shown). The fan-shaped friction material 10 falls from the supply port 62 at the end of the supply path 60. However, for the sake of completeness, the fan-shaped friction material 10 may be moved downward by a pressing rod whose outer shape is slightly reduced. it can.

  The gap between the supply port 62 of the supply path 60 and the bottom surface 31c of the annular groove 31 is a slight height, and the falling fan-shaped friction material 10 receives a slight vector force by the inner peripheral wall 31e. The fan-shaped friction material 10 is lowered with the inner peripheral wall 31e as a reference point. The fan-shaped friction material 10 slightly moves on the inner peripheral wall 31e until the lower surface of the fan-shaped friction material 10 reaches the bottom surface 31c, and the fan-shaped friction material 10 is disposed on the bottom surface 31c. Therefore, the fan-shaped friction material 10 is placed on the bottom surface 31c with the inner peripheral wall 31e as a reference.

For example, FIG. 1 shows a state where the inside of the fan-shaped friction material 10 _-1 of the supply path 60 reaches the arrangement position from the supply port 62 and is arranged. Further, FIG. 4, during delivery a fan friction member _10-2 from the supply port 62 of the end portion of the supply channel 60, FIG. 5 shows a state in which an array of 10 _-8 from sector the friction material 10 _-1.
In FIG. 2, the fan-shaped friction material 10 _-1 dropped from the supply port 62 of the supply path 60 is placed on the bottom surface 31 c, and the base means 30 rotates clockwise by 45 degrees, so that the supply port of the supply path 60 is provided. The supply process of arranging the next fan-shaped friction material 10 _-2 from 62 is shown.

  In this manner, the fan-shaped friction material 10 is sequentially placed on the upper surface of the bottom surface 31c of the annular groove 31 while the base means 30 and the annular groove 31 are sequentially rotated by 45 degrees. At this time, as shown in FIG. 2, there is a slight gap from the supply port 62 to the bottom surface 31c of the annular groove 31, and the falling fan-shaped friction material 10 comes into contact with the inclined surface of the inner peripheral wall 31e. More specifically, the fan-shaped friction material 10 in contact with the inner peripheral wall 31e receives a slight vector force due to its own weight, but its air resistance or the like acts to slide on the inner peripheral wall 31e. Therefore, the fan-shaped friction material 10 is placed on the bottom surface 31c without rotating. The fan-shaped friction material 10 slightly moves on the inner peripheral wall 31e before the fan-shaped friction material 10 arrives at the bottom surface 31c, and this becomes the reference position of the fan-shaped friction material 10.

  Naturally, the center disk portion 35 has a distance between the upper end portions 31 a passing through the center shorter than a distance between the lower end portions 31 b, and the base means 30 is proportional to the depth of the annular groove 31. Since the distance between the end portions passing through the center of the fan is increased, the fan-shaped friction material 10 dropped into the annular groove 31 receives an appropriate air resistance. While being guided by the outer peripheral wall 31d of the outer peripheral guide portion 32 of the annular groove 31, it is determined at a predetermined position.

As shown in FIG. 5A and FIG. 5B showing the arrangement state of the fan-shaped friction materials 10, eight fan-shaped friction materials 10 are arranged on the bottom surface 31 c. When the upper portions of the eight fan-shaped friction materials 10 rotate with respect to the peripheral wall 31e, the eight fan-shaped friction materials 10 are sequentially arranged on the bottom surface 31c so that the end portions of the eight fan-shaped friction materials 10 are in close contact with each other. Touch.
In this state, the eight fan-shaped friction materials 10 become an annular friction material 10A in which eight sheets are continuous. However, since the contact of the end portions of the eight fan-shaped friction materials 10 is left only to its own weight, there may be a case where the joints between the end surfaces do not necessarily match.
Therefore, the pressing / moving means 50 presses the plurality of fan-shaped friction materials 10 arranged in the annular groove 31 to form the annular annular friction material 10A, and moves them to the next step.

A description showing the gap state at the time of supplying the sector friction material at this time will be described with reference to FIGS.
As shown in FIG. 4, an interval of δ ₁ is initially formed between the fan-shaped friction material 10 _-1 placed on the bottom surface 31c and the fan-shaped friction material 10 _-2 to be placed on the bottom surface 31c. After that, when the fan-shaped friction material 10 _-2 is moved, an interval of δ ₂ (δ ₁ > δ ₂ ) is formed at the end of the fan-shaped friction material 10 _{-1 and} the end of the fan-shaped friction material 10 _-2 . When the ends of the fan-shaped friction member _10-2 comes in contact with the inner peripheral wall 31e, at the same time, contact with the ends of the fan-shaped friction member _10-2 to the end of the sector the friction material 10 _-1 equivalent, fan friction member 10 _-1 The gap between the end and the end of the fan-shaped friction material 10 _-2 becomes zero.

In this manner, the fan-shaped friction material 10 is sequentially conveyed so that the center line corresponding to the diameter thereof coincides with the direction of the supply path 60 delivered by the pushing means 63. When the fan-shaped friction material 10 _-1 to the fan-shaped friction material 10 _-8 are sequentially inserted along the annular groove 31 of the base means 30, the inner end portions of the fan-shaped friction material 10 _-1 to the fan-shaped friction material 10 _-8 are It abuts against the inner peripheral wall 31e and becomes the reference position, and can be sequentially arranged and aligned as the base means 30 rotates. When the fan-shaped friction material 10 is sequentially inserted into the annular groove 31 of the base means 30 with the rotation of the base means 30, centrifugal force is applied by the rotation of the base means 30, but only a slight interval is provided. since guided to the outer peripheral wall 31d of the annular groove 31, the inner peripheral wall 31e abutting the reference position of the sector the friction material 10 _-8 fan shape friction member 10 _-1 is not changed. Further, when a centrifugal force is applied by the rotation of the base means 30, the fan-shaped friction material 10 comes into contact with the outer peripheral wall 31d of the annular groove 31 of the base means 30, but the outer peripheral wall 31d does not move. There is a possibility that the rotation angle of the fan-shaped friction material 10 is smaller than the rotation angle of the base means 30.

However, even if the rotation angle on the side of the fan-shaped friction material 10 _-1 decreases, when the fan-shaped friction material 10 _-2 to be placed next is inserted, the fan-shaped friction material 10 _-2 becomes the fan-shaped friction material 10. _-1 is pressed in the rotational direction to secure the space for the fan-shaped friction material 10 _-2 , so the fan-shaped friction material 10 _-1 side must move in the rotation direction, and the gap between the end portions of the fan-shaped friction material 10 is forced to move. Close end joining is performed so that there is no loss.
That is, when the fan-shaped friction material 10 is sequentially inserted into the annular groove 31 of the base means 30 as the base means 30 rotates, an interval of δ ₁ is initially formed between the ends of the fan-shaped friction material 10. but if narrows until interval 2.delta. _1/3, just before contact with the inner peripheral wall 31e is an end of the fan-shaped friction member 10 _-2 when fan friction member _10-2 is moved, the bottom surface of its ends annular groove 31 Abuts 31c. At this time, since the end portion of the fan-shaped friction member _10-2 to the end of the sector the friction material 10 _-1-side do not overlap, it is possible to orderly arrangement.

In this manner, the fan-shaped friction material 10 is sequentially placed on the upper surface of the bottom surface 31c of the annular groove 31 while the base means 30 is sequentially rotated by 45 degrees. As a result, the fan-shaped friction material 10 in contact with the inner peripheral wall 31e is placed on the bottom surface 31c without rotating the fan-shaped friction material 10 due to its own weight, so that the inner peripheral wall 31e becomes the reference position of the fan-shaped friction material 10.
Here, in a state where the eight fan-shaped friction members 10 are arranged in an annular shape in the annular groove 31 of the base means 30, the annular lower portion 51 of the pressing / moving means 50 is used to form the bottom surface 31 c of the annular groove 31. The annular friction material 10A is pressed to bring out the smooth surface of the annular friction material 10A, and the ridge can be formed in an annular shape like the annular friction material 10A having eight radial slits.

Then, in this state, suction is performed from the suction head 55 provided on the annular lower portion 51 of the pressing / moving means 50, and the annular friction material 10A is held on the lower surface of the annular lower portion 51, and the core metal of the next lockup clutch. Or it conveys to the adhesive application process with respect to the piston member of a lockup clutch, and a joining process.
In the present embodiment, the supply of the sector friction material 10 is described as being supplied from the single supply path 60, but the supply of the sector friction material 10 can also be supplied from two or more supply paths 60.
In particular, when the fan-shaped friction material 10 is supplied simultaneously from the eight supply paths 60, the annular friction material 10A can be formed at a speed of 1/8 that of the present embodiment.
[Embodiment 2]

In the first embodiment, the fan-shaped friction material 10 is supplied from one supply path 60.

The conveying surface 65 of the supply path 60 is made to have the same height as the bottom surface 31 c of the annular groove 31 at the supply port 62.

The fan-shaped friction material 10 is sent out by the supply path 60 sent out by the pushing means 63 so that the center line of the diameter of the fan-shaped friction material 10 coincides with the straight line of the diameter of the base means 30, and the diameter of the disk portion 35. Are sequentially conveyed so as to match the straight line. When the fan-shaped friction material 10 _-1 to the fan-shaped friction material 10 _-8 are sequentially inserted following the annular groove 31 of the base means 30, there is an interval of δ ₁ between the ends of the original fan-shaped friction material 10. Since it is formed, it is possible to arrange the gap with the largest possible size.
In the third embodiment, when the fan-shaped friction material 10 _-1 to the fan-shaped friction material 10 _-8 are inserted along the annular groove 31 of the base means 30, δ is inserted between the ends of the initial fan-shaped friction material 10. _Since the maximum interval of ₁ is formed, the gap is maximized, and even if there is a large error in the insertion position of the fan-shaped friction material 10 inserted and arranged first, the next fan-shaped friction material 10 is inserted. This is corrected along with the placement, and the placement accuracy increases.

In particular, in the third embodiment, when the fan-shaped friction material 10 is placed in the annular groove 31 when the supply path 60 is sent out by the pushing means 63, the fan-shaped friction material 10 is arranged at both ends. The friction material 10 is pushed out. That is, the finishing accuracy of the annular friction material 10 </ b> A depends on the process of feeding the supply path 60 by the pushing means 63.
Therefore, when the reference position is set for the fan-shaped friction material 10 conveyed from the supply port 62 of the supply path 60, the accuracy becomes higher. Embodiment 4 is an example.
[Embodiment 4]

FIG. 8 is an explanatory view of a cross section showing the operation of the principal part of the lockup clutch friction plate assembling apparatus according to the fourth embodiment of the present invention, and is a view corresponding to FIG. 4 of the first embodiment.
The conveying surface 65 of the supply path 60 is made to have the same height as the bottom surface 31 c of the annular groove 31 at the supply port 62. When the fan-shaped friction material 10 _-1 is arranged and then the fan-shaped friction material 10 _-2 is arranged, press bars 66 a and 66 b for moving both ends of the fan-shaped friction material 10 by pressing are provided as a conveyance auxiliary tool 66. In addition, an end abutting bar 66c for specifying the surface of the opposite end portion that is not the opposite end portion on the fan-shaped friction material _10-1 side supplied to the annular groove 31 previously is provided.
These pressing bars 66 a and 66 b and the end contact bar 66 c are normally disposed on the robot hand disposed above the base means 30 and the supply path 60.

Next, the operation of the conveyance assisting tool 66 will be described.
The fan-shaped friction material 10 is sent by the supply path 60 sent by the pushing means 63 so that the center line of the fan-shaped friction material 10 coincides with the straight line of the diameter of the base means 30, and becomes the straight line of the diameter of the disk portion 35. It is sequentially conveyed so as to match. The fan-shaped friction material 10 of the supply port 62 of the supply path 60 delivered by the pushing means 63 is stopped immediately before the annular groove 31.
In the figure, the sector friction material 10 _-1 has already been supplied to the annular groove 31 and the base means 30 has been rotated 45 degrees, and the sector friction material 10 _-2 has been conveyed to the outside of the annular groove 31. Yes. Accordingly, the pressing bars 66 a and 66 b are lowered, and the center of the fan-shaped friction material 10 is moved toward the center of the base means 30 on both ends of the outer peripheral surface of the fan-shaped friction material 10 _-2 . Lower the end abutment bar 66c on the end of the simultaneous or substantially sector friction member _10-2 at the same time, to abut against the ends of the fan-shaped friction member 10 _-2.

The center line of the fan-shaped friction material 10 _{-2 is} the center of the base means 30 and is moved toward the center of the disk portion 35 by the pressing bars 66a and 66b and the end contact bar 66c of the conveyance assisting tool 66. . The fan-shaped friction material 10 _-2 is moved until the inner periphery contacts the inner peripheral wall 31 e of the annular groove 31. At this time, the end abutment bar 66c serves as a reference edge position of the fan-shaped friction member 10 _-2. Therefore, the fan-shaped friction material 10 is sequentially conveyed by the supply path 60 sent out by the pushing means 63 so that the center line of the fan-shaped friction material 10 matches a straight line passing through the diameter of the base means 30. When the fan-shaped friction material 10 _-1 to the fan-shaped friction material 10 _-8 are sequentially inserted following the annular groove 31 of the base means 30, there is an interval of δ ₁ between the ends of the original fan-shaped friction material 10. Since it is formed, it is possible to arrange the gap with the largest possible size. In addition, when the fan-shaped friction material 10 is installed, the end contact bar 66c forms a reference surface, so that an annular friction material 10A in which the fan-shaped friction material 10 is arranged uniformly with little error is obtained.

By the way, although the conveyance auxiliary tool 66 of this Embodiment has arrange | positioned press bar 66a, 66b and the edge part contact bar 66c, when implementing this invention, the edge part of the sector-shaped friction material 10 is provided. The interval between the fan-shaped friction materials 10 _-1 to the fan-shaped friction material 10 _-8 is sequentially increased by inserting the fan-shaped friction material 10 _{-8 following the} annular groove 31 of the base means 30. However, since it is corrected together with the insertion arrangement of the next fan-shaped friction material 10 and the arrangement accuracy is increased, the end contact bar 66c can be omitted.
Further, the pressing bars 66a and 66b of the conveyance assisting tool 66 may be formed separately, connected by a plate material, or may be formed by notching a U-shape with a plate material.

In each of the above embodiments, when the fan-shaped friction material 10 _-1 to the fan-shaped friction material 10 _-8 are inserted following the annular groove 31 of the base means 30, even if the error in the insertion position of the fan-shaped friction material 10 is large. As described above, the insertion and placement of the fan-shaped friction material 10 is corrected and the placement accuracy is improved. However, a fixing means is provided for fixing the position of the fan-shaped friction material 10 when inserted following the annular groove 31. Can also be implemented.

In the present embodiment, when the fan-shaped friction material 10 is inserted by the fixed holding means 36 following the annular groove 31 of the base means 30, it is held. The fixed holding means 36 may be shared with the pressing / moving means 50 or may be a leaf spring. In any case, it is only necessary that the arranged fan-shaped friction materials 10 can be fixed so as not to move.

In each of the above-described embodiments, the outer peripheral guide portion 32 has been described as a structure that is not formed integrally with the annular groove 31 or the base means 30.
However, when the present invention is carried out, the outer peripheral guide portion 32 can be formed integrally with the annular groove 31 or the base means 30. In particular, when the outer circumferential guide portion 32 is not formed integrally with the annular groove 31 or the base means 30, the position of the sector friction material 10 is changed by the contact between the sector friction material 10 and the outer circumferential wall 31d. However, when the outer circumferential guide portion 32 is formed integrally with the annular groove 31 or the base means 30, the positional information initially arranged in the annular groove 31 is maintained until the end, so that the supply accuracy Depending on the case, it may be better to form the outer peripheral guide portion 32 integrally with the annular groove 31 or the base means 30. However, the degree of freedom in setting the supply path 60 is restricted when the outer peripheral guide portion 32 is formed integrally with the annular groove 31 or the base means 30.

In each of the above embodiments, the bottom surface 31c of the annular groove 31 of the base means 30 is the bottom surface 31c having a uniform height on the outer peripheral wall 31d side and the inner peripheral wall 31e side of the annular groove 31. However, if the bottom surface 31 c is inclined, there is a margin in the gap in which the fan-shaped friction material 10 is disposed, and the pressing / moving means 50 can be used for finishing. Embodiment 5 is an example.
[Embodiment 5]

FIG. 10 is an explanatory view of a cross section showing the operation of the main part of the lockup clutch friction plate assembling apparatus according to the fifth embodiment of the present invention, and corresponds to FIG. 2 of the first embodiment.
In FIG. 10, the bottom surface 31c of the annular groove 31 is divided into three sections. In other words, the disk portion 35 is continuously formed with protrusions 37. The upper surface 37b of the protrusion 37 is a part of the bottom surface 31c. The annular member 38 and the annular member 39 are connected to the rod 38a and the rod 39a, respectively, and the rod 38a and the rod 39a are moved up and down by hydraulic pressure, a link mechanism or the like (not shown), and the upper portion 38b and the annular member of the annular member 38 are moved. The upper portion 39b of 39 forms the bottom surface 31c of the disk portion 35 together with the upper surface 37b of the protrusion 37.

The fan-shaped friction material 10 is sent out along the supply path 60 by the pushing means 63. That is, the center line of the fan-shaped friction material 10 is a straight line having a diameter passing through the center of the base means 30 and is sequentially conveyed so as to coincide with the straight line of the diameter of the disk portion 35. The fan-shaped friction material 10 of the supply port 62 of the supply path 60 delivered by the pushing means 63 is transferred to the annular groove 31.
In the figure, the fan-shaped friction material 10 _-1 is already supplied to the annular groove 31. Here, as shown in FIG. 10A, the fan-shaped friction material 10 is disposed obliquely, so that there is room for the width direction of the annular groove 31 (the diameter direction of the base means 30). In addition, a gap is generated between the end surfaces of the fan-shaped friction materials 10, and a clearance is generated.

Therefore, when the rod 38a and the rod 39a are lifted and the upper surface 38b of the annular member 38 and the upper surface 39b of the annular member 39 are formed together with the upper surface 37b of the projection 37, the same configuration as in the first embodiment is obtained. Here, the annular friction material 10A in which the fan-shaped friction material 10 is arranged uniformly is obtained.
Here, the annular lower portion 51 of the pressing / moving means 50 is used in a state in which the eight fan-shaped friction materials 10 _-1 to 10 _-8 are annularly arranged in the annular groove 31 of the base means 30. The annular friction material 10A is pressed against the bottom surface 31c of the annular groove 31 to bring out the smooth surface of the annular friction material 10A, and the flange is formed in an annular shape like the annular friction material 10A having eight radial slits.
In this way, in the case where there is a clearance between the fan-shaped friction material 10 and the width of the annular groove 31, the outer peripheral wall 31d and the inner peripheral wall 31e of the annular groove 31 can be perpendicular to the bottom surface 31c. . In particular, the inner peripheral wall 31e of the annular groove 31 of the base means 30 has a radial cross-sectional shape that is slightly smaller than the distance between the upper ends 31a passing through the center and the lower ends 31b passing through the center. It can also be formed longer.

  As described above, the lock-up clutch friction plate assembling apparatus according to the embodiment of the present invention is mounted on the bottom surface 31c in which the plurality of fan-shaped friction materials 10 are arranged in an annular shape, and on the annular bottom surface 31c. Base means 30 having an annular groove 31 formed of an inner peripheral wall 31e for regulating the inside of the fan-shaped friction material 10 and an outer peripheral wall 31d for regulating the outside of the fan-shaped friction material 10 placed on the annular bottom surface 31c. A plurality of fan-shaped friction materials 10 are sequentially fed one by one toward the inner peripheral wall 31e side of the annular bottom surface 31c, and a plurality of sheets are inserted into the annular groove 31 of the base means 30. After the fan-shaped friction material 10 is arranged in an annular shape, pressing means (pressing / moving means 50) for pressing the plurality of fan-shaped friction materials 10 in an annular shape is provided.

  Therefore, since the plurality of fan-shaped friction materials 10 can be taken out as an annular shape without using an area larger than the annular groove 31, the apparatus can be manufactured with a small installation area. Further, unlike the conventional example, the annular groove 31 is fixed and does not have a surplus space. Therefore, the plurality of fan-shaped friction materials 10 are supplied by rotating the fan-shaped friction materials 10 sequentially or simultaneously. Even when the two are supplied substantially simultaneously, the plurality of fan-shaped friction materials 10 do not move, so that high-speed work is possible. In particular, the speed of arranging the plurality of fan-shaped friction materials 10 into an annular shape can be further increased depending on the number of supply paths 60 installed.

  Further, the pressing means (pressing / moving means 50) sucks the plurality of fan-shaped friction materials 10 formed in an annular shape, and sucks the plurality of fan-shaped friction materials 10 in a state of being formed in an annular shape. The workpiece moving means (pressing / moving means 50) for moving the plurality of fan-shaped friction materials 10 formed in the above is provided.

The annular groove 31 of the base means 30 is formed in a trapezoidal shape with the cross-sectional shape cut in the diameter direction having a wide upper side, and thus moves to a specific molding position, that is, a molding position of the bottom surface 31c. It is guided by the surfaces of the inner peripheral wall 31e and the outer peripheral wall 31d in between, and a plurality of fan-shaped friction materials 10 can be formed in an annular shape with high accuracy.
Further, the bottom surface 31c of the annular groove 31 of the base means 30 is such that the outer peripheral side of the annular groove 31 is formed with a difference in height from the inner peripheral side thereof, so that the inner peripheral side of the annular groove 31 is used as a reference. In this case, an interval can be formed on the outer peripheral side of the annular groove 31, and it can be guided to the annular shape without excessive arrangement, and the finishing accuracy can be increased.
The outer peripheral wall 31d for regulating the outside of the fan-shaped friction material 10 placed on the annular bottom surface 31c of the base means 30 is a separate member from the annular bottom surface 31c and the annular inner peripheral wall 31e of the base means 30. Since it is formed, the outer peripheral wall 31d of the annular groove 31 has a high degree of design freedom, and an arbitrary bottom surface can be set together with the conveying surface 65 of the supply path 60.

Since the conveying surface 65 of the supply path 60 is substantially flush with the annular bottom surface 31c of the base means 30, a necessary gap can be formed between the ends of the fan-shaped friction material 10, and finishing accuracy can be increased. can do.

Further, the fan-shaped friction material 10 delivered from the supply path 60 is pressed on both sides of the peripheral surface of the large-diameter portion of the fan-shaped friction material 10, positioned at both ends of the fan-shaped friction material 10, and moved to assist. Since the tool 66 is provided, stable position setting can always be performed, and the accuracy of the setting position of the fan-shaped friction material 10 can be further increased.

  Since a plurality of supply paths 60 for delivering the fan-shaped friction material 10 toward the inner peripheral wall 31e side of the annular groove 31 are provided around the annular groove 31, the speed of arranging the fan-shaped friction materials 10 is increased. can do. In particular, in the case where supply paths 60 corresponding to the number of fan-shaped friction materials 10 that are circular are arranged, the fastest processing can be performed.

The lockup clutch friction plate assembling apparatus according to the embodiment of the present invention can be regarded as a method of assembling the lockup clutch friction plate.
