The assembly apparatus constructed as described above is fully automatically controlled.

Next, automatic mounting of a plurality of perforated parts using the above-described assembly apparatus will be explained.

First, the head (56) of the first parts transfer 41 (51) moves above the parts take-out machine (11) of the governor parts feeder (1), and the air cylinder (12) reciprocates as shown in Fig. 2. The parts holder of the extraction plate (14) is located in the recess (1).
5) The governor (131) taken out inside the holder shirt (81) is operated by the air cylinder (57) from above.
) descends and penetrates, and rises again to hold the governor (131) on the holder shaft (81) while preventing the governor (131) from falling out with the claw (82). Next, the head (5B) is the parts take-out machine (21) of the parts feeder (3) for flat washers.
The reciprocating operation of the air cylinder (22) moves the ejection plate (20) upward, and as shown in Fig.
The holder shaft (131) descends and penetrates the flat washers (13B) taken out inside, and rises to form the claws (62).
The flat washer (13B) is stacked under the governor (131) and held on the holder shaft (61) in the same way while preventing the drawer from falling off. Subsequently, the head (56) moves above the pin (45) located at the first part transfer position (A) of the turntable (41) as shown in Fig. 5, and the holder shirt (H) descends to the 8th part transfer position (A). As shown in the figure, the narrow diameter part (46) at the upper end of the pin (45)
A tapered recess (63) at the lower end of the shaft (ftl) fits into the air cylinder (59) for centering.
The ejector (84) is lowered by the operation of
32) Hit the upper surface of the gear (133) at the upper end and push it down, thereby pushing in the pawl (62) and removing the flat washer (13B).
) and the governor (131) are removed from the shaft (61) and transferred to the outer periphery of the pin (45). Thus the pin (45)
The flat washer (13fl) and the governor (131) thereon are positioned on the claw (48) protruding into the large diameter part (44a) at the upper end of the pin hole (44) as shown in FIG. Moreover, there is a 4Liff-shaped frame on the upper surface of the holder (43).

After that, the ejector (64) and the holder shaft (B1
) rises and the head (56) heads to take out the parts again, and the turntable (41) sequentially makes 1/8 rotation and each time similarly moves to the next pin (A) at position (A).
The parts are transferred to 45).

On the other hand, the head (74) of the second parts transfer machine (71) is connected to both parts feeders (for chestnuts and thrust washers).
The parts take-out machine (31) common to 5) and (7) moves upwards, and by the reciprocating operation of the air cylinder (32), the parts receiver on the left side of the take-out plate (34) is removed from the four parts (35
) The holder shaft (81) descends and penetrates the thrust washer (138) taken out from above by the operation of the air cylinder (75), and then rises again to prevent the thrust washer (138) from falling out by the claw (82). Thrust washer (13)
8) is held in the holder shirt) (81). Continuing with the reciprocating action of the air cylinder (page 32), the parts receiver on the right side of the extraction plate (34) will be lowered and penetrated by the clip (+37) taken out into the fourth part (35), and then raised. The clip (137) is stacked under the thrust wansha (138) and held on the holder shaft (81) in the same manner while preventing the clip (137) from falling out with the claw (82).

Then, as mentioned above, the pin (13B) and the pin (131) attached to the first part transfer position (A)
45) is the turntable (41) 2 from position (A).
When the head (74) reaches the second part transfer position (B) by forward rotation, the pin (45) at the position (B) as shown in Figure 6.
) moves upward, and the holder shirt (81) descends, and as shown in Fig. 9, the acid tapered recess (83) at the lower end of the shaft (81) fits into the narrow diameter part (46) at the upper end of the pin (45). Then, the ejector (84) is lowered by the operation of the air cylinder (77), and in the process, the ejector (84) is
84) The lower end touches the upper surface of the thrust washer (138) and pushes it down, thereby pushing the claw (82) and causing the clip (137) and thrust washer (138) to fall off the shaft (81) and remove the pin (45). Transfer to the outer periphery.

In this case, a pair of weights (+3
4) and (134) are incorporated, and even if these weights (134) and (134) are raised toward the center of the governor (131), there is no problem in inserting the holder shirt (81). , clip (1) to pin (45)
37) and the thrust washer (138), if the way (134), (134) is raised, it will be an obstacle to the installation.

For this reason, as shown in FIGS. 12 and 13, an air nozzle device (111) is provided on the turntable (41), especially near the second parts transfer position (B), and its nozzle (112) is attached to the pin (45) (+31
) is oriented tangentially to the outer periphery of the gear (+33). Then, prior to attaching the clip (+37) and thrust washer (138) to the pin (45), air is blown from the nozzle (112) to the gear (133) so that the governor holder (+
32) is rotated, and the centrifugal force due to the rotation causes way)
(134) and (134) are operated to expand. Therefore, the next clip (+37) and thrust wansha (138) can be attached smoothly.

Note that the air nozzle device (111) may not be provided directly on the table (41) as shown in the figure, but may be separately installed near the position (B), and the air blowout may be performed constantly or intermittently as necessary. You may also do this as follows.

After that, the ejector (84) and holder shaft [81
) rises and the head (74) heads to take out the parts again, and the turntable (41) sequentially performs 178 rotations and each time similarly moves to the next pin (B) at position (B).
The parts are transferred to 45).

As a result of the above, the four perforated parts, the flat washers (
IH), governor (i31), clip (137), and thrust oneshaft (138) are both in the parts transfer position (A)
, (B), when the pin (45) installed through position (B) comes to the pin take-out and return position 21 (C) by two feed rotations of the turntable (41) from position (B), it is moved to this position (C). )
The head (94) of the pin JGafi (91) is waiting above the pin (45) located at ) fits on the upper outer periphery of the

Subsequently, by the operation of the air cylinder (95), the collet chuck (101) is intermittently lowered onto the pin (45), and further by the operation of the actuating device (102), the collet chuck (101) is lowered onto the pin (45).
101) chunks the narrow diameter portion (46) at the upper end of the pin (45). Next, the collet chunk (101) and the ejector (104) rise synchronously and extract the pin (45) from the turntable (4z) as shown in FIG. 7, after which the head (94) moves onto the assembly conveyor ( 120) The workpiece (121) that is stopped and waiting moves upward, and the governor shaft (12) inside the workpiece (121) moves as shown in FIG.
4) The collet chuck (101) and the ejector (104) descend synchronously again, and the pin (4) is attached to the male taper part (125) at the upper end of the governor shirt (124).
5) The acid tapered portion (47) at the lower end is fitted to perform centering. Subsequently, the ejector (104) further descends, and its lower end hits the upper surface of the thrust washer (138) and pushes it down, thereby pushing in the claw (48) and releasing the flat washer (138), governor (131), and clip ( 137
) and the thrust washer (138) are removed from the pin (45) and transferred to the outer periphery of the governor shirt (124). At this time, the clip groove (12B of the shirt) (124)
) is fitted with a clip (137).

After that, ejector (100) and collet chuck (1
01) rises, the head (94) returns to position (C), and comrades lowers the collet chuck (101) onto the pin hole (44) at position (C) of the turntable (41). Insert the pin (45) into the pin hole (44) and return it, expand the chuck (101) to release the chuck, and rise again to wait for the next work.

The pin (4) thus returned onto the turntable (41)
5) When the table (41) performs 1/8 rotation four times and comes to the first part transfer position (A), the parts are mounted again in the same manner, and the operation is repeated in the same procedure thereafter. .

Incidentally, although the embodiments have been described based on the assembly of governor parts, it goes without saying that the assembly method and apparatus of the present invention can also be applied to other plurality of perforated parts. Further, a parts take-out machine and a parts transfer machine may be provided individually depending on the type of parts, and furthermore, the number of pins and the index rotation angle of the turntable can be set arbitrarily.

(Effects of the Invention) As described above, according to the present invention, the parts transfer machine sequentially transfers a plurality of perforated parts taken out from each parts feeder onto the pins on the turntable, and then transfers the parts with holes to the pins on the turntable. The mounting machine removes the pin after the component has been mounted from the table, carries it above the workpiece on the assembly conveyor, transfers the component from the pin to the shaft, and then returns the pin to the table, which requires manual labor. Multiple perforated parts can be transferred and mounted efficiently from the parts feeder to the shaft on the assembly conveyor, achieving automation.
