In FIG. 4, reference numeral 44 denotes a bracket that supports the gear box 40, and 45 denotes a slide table that guides the bracket 44.

Next, the clutch assembling operation of the above device will be described.

A clutch disc d and a clutch plate p that are stored in 1
With the set of cassettes 20d and 20p positioned on the reversing table 22, the lowest works d and p stored in the cassettes 20d and 20p are stored in the discharge holes 16d and 16p of the cassette table 15, respectively. Inversion table 22
Is on top.

In this state, the reversing table 22 is now rotated counterclockwise in FIG.
When positioned just below d (FIG. 8), the lowest clutch disc d is captured in the hole 23 of the reversing table 22, and then the reversing table 22 is rotated in the reverse direction so that the hole 23 accommodating the clutch disc d is opened. When the clutch disk d is positioned above the discharge hole 13 of the fixed table, the clutch disk d is fixed to the fixed table 12
Along with the work hole 2 just below the discharge hole 13
Store in 4 On the other hand, in this rotating position, the other hole 23 of the reversing table 22 is located immediately below the plate storing cassette 20p of the cassette table 14 and captures one of the clutch plates p accommodated therein. By rotating the reversing table 22 again in the counterclockwise direction in the figure to position this hole 23 on the discharge hole 13 of the fixed table 12, the captured clutch plate p is dropped into the work receiver 24 and is already accommodated. It is stacked on the clutch disk d that is being mounted.

Therefore, if the above operation is repeated, for example, three times, the work receiver 24 is laminated with the three clutch disks d and the clutch plates p required for one clutch.
The work receiving and transporting cylinder 25, which has started its operation after the completion of this operation, moves the work receiving unit 24 integrated with the work receiving and transporting cylinder 25 onto the work receiving rotating body 52.

On the other hand, on the assembly mechanism 30 side, the guide transport conveyor 57
The clutch guide g conveyed by the push-up cylinder 59 is transferred to the lower jig 54 of the work receiving rotary body 52.
Is pressed and fixed to. When this operation is completed, the disk positioning cylinder 33 which has started its operation by the confirmation signal.
Lowers the disk positioning guide 31 via the rod 34, and penetrates the inner holes of the clutch disk d and the clutch plate p, which are stacked and held in the work receiver 24, to perform positioning of these. The work receiver 24 retreats while allowing the claws 28 holding the stacked body to escape to the outside, and returns to immediately below the discharge hole 13 of the fixed disk 12 to prepare for the next member supply.

On the other hand, the laminated body which has lost the support by the work receiving member 24 is guided by the outer periphery of the disk positioning guide 31 and drops onto the work receiving rotating member 52, and from here, between the convex guides 56 of the work receiving rotating member 52. The clutch plate p with which the claw pc is matched falls into the work receiving rotary body 52 together with the clutch disc d immediately above it, but the others are blocked by the auxiliary roller 55 and remain there.

Next, when the return of the work receiver 24 is confirmed, the guide insertion cylinder 43 and the rotating body driving motor 42 start to operate, and the plate pressing rotating body 35 and the outside are further moved under the condition that the disc positioning guide 31 is lowered. The cylinder 46 is rotated and lowered, and first, the plate pressing rotary member 35 is pressed against the stacked members by the pressing force of the coil spring 39 to transmit the rotational force to these and rotate the clutch plate p on the auxiliary roller 55. Then, these are sequentially accommodated in the work receiving rotary body 52 while matching the claw pc between the convex guides 56.

At this time, even if the claw pc of the clutch plate p fits between the convex guides 56, the claw pc may be pushed and pressed during this period, which may make it difficult for the device to fall. After rotating the 35 in the same direction several times, it is slightly rotated in the opposite direction to make it easier to drop.

When all the stacked bodies fall into the work receiving rotary body 52 in this way, following the lowering of the plate pressing rotary body 35, the outer cylinder 46 pushed down by the guide insertion cylinder 43 via the coil spring 51 moves to the plate. Each clutch held by engaging the spline groove 36 of the pressing rotary member 35 with the pin 48 while rotating and descending, and engaging the pin 47 on the lower end surface thereof with the groove 53 of the workpiece receiving rotary member 52. The work receiving rotary body 52 is rotated to a position where the claw pc of the plate p matches the groove gc of the clutch guide g.

Then, when the point of time of coincidence is reached, the plate pressing rotary body 35 releases the engagement with the pin 48 of the outer cylinder 46 and further descends, and sequentially drops the laminated body into the clutch guide g, while the driving force is applied. The disconnected outer cylinder 46 receives the resistance of the clutch guide g in a stationary state through the laminated body which is in the process of falling into the clutch guide g, and therefore stops at the matching position while idly rotating the overrunning clutch 49 at the upper end thereof. .

Therefore, thereafter, the plate pressing rotary body 35 rotates while slipping with the laminated body, and the laminated body is sequentially dropped into the clutch guide g by the pressing force of the coil spring 39 acting on itself, and a series of assembling work is performed. To finish.

When the above series of inserting operations is completed, the disc positioning guide 31, the plate pressing rotary member 35, and the outer cylinder 46 are returned to their original positions again, and the guide lifting cylinder 59 is lowered to complete the assembly of the clutch guide. g is placed on the guide transfer conveyor 57 and is transferred to the next step.

By such a series of operations, the cassette table 14
The upper clutch disc d and the clutch plate p are sequentially supplied and assembled in the clutch guide g, but when all these members are ejected from the cassettes 20d and 20p on the reversing table 22, the motor operated by the detection signal. The cassette table 14 is rotated 1/4 by 15 to position the next cassette 20d, 20p on the reversing table 22.

(Effect) As described above, according to the present invention, the clutch discs and the clutch plates are alternately stacked, and the stacked stacks are pressed while being rotated, so that the pawls of the clutch plates are not passed through the inner peripheral surface. Since it is configured to be assembled in the clutch guy by aligning it in an aligning member having a guide part that enables it, it is possible to automate this kind of work that was left to humans, and the assembly order is erroneous and the parts are While eliminating quality problems such as lack of points,
It is possible to greatly save labor and shorten the time required for assembly.
