And the plurality of leg pieces 20 are moved in the vertical direction between the lower limit position P5 (see FIG. 4) at which the stop ring 10 is mounted in the stop ring mounting groove 16.

Next, a case where the stop ring 10 is mounted in the stop ring mounting groove 16 by the mounting member mounting apparatus will be described.
As shown in FIGS. 1 and 2, when the workpiece 12 is moved to the mounting position P1 by the first robot arm R1, the guide member 22 is lowered from the standby position P2 to the contact position P3.
When the guide member 22 is lowered from the standby position P2 and approaches the workpiece 12, first, the conical portion 2904 of the guide pin 29 is inserted into the hole 1204 of the workpiece 12, and then the cylindrical portion 2902 is inserted. Even when the shaft center and the shaft center of the outer peripheral surface 1202 of the workpiece 12 are deviated from each other, they are automatically aligned and become the contact position P3.
When the guide member 22 is positioned at the contact position P3, the guide member 22 and the workpiece 12 are positioned in a state where the inclined guide surface 28 and the outer peripheral surface 1202 of the workpiece 12 are continuous. Therefore, in the present embodiment, the positioning means 24 is configured by the first robot arm R1 and the guide member actuator 30.

Then, the axis of the stop ring 10 is aligned with the axis of the inclined guide surface 28 from the supply portion R2-1 at the tip of the second robot arm R2 to the inclined guide surface 28 of the guide member 22 located at the contact position P3. Then, the stop ring 10 is placed. The stop ring 10 may be placed on the inclined guide surface 28 while the guide member 22 is positioned at the standby position P2. In the present embodiment, the second robot arm R <b> 2 constitutes the supply means for the stop ring 10.
The stop ring 10 does not need to be precisely aligned with the inclined guide surface 28, and the plurality of leg pieces 20 are placed in a state where the stop ring 10 is placed on the inclined guide surface 28. Any posture may be used as long as all the tips 2002 are in contact with the stop ring 10. Even if the axes are slightly deviated from each other, the axis of the inclined guide surface 28 and the axis of the stop ring 10 are matched by the lowering of the plurality of leg pieces 20.

When the stop ring 10 is placed on the inclined guide surface 28, the plurality of leg pieces 20 are lowered from the upper limit position P4 to the lower limit position P5 as shown in FIGS.
By moving the plurality of leg pieces 20 downward, first, the tips 2002 of the leg pieces 20 that are not elastically deformed are spaced apart in the circumferential direction of the stop ring 10 in a reduced diameter state where no external force is applied. The posture of the stop ring 10 is determined by the tips 2002 of the plurality of leg pieces 20 and the inclined guide surfaces 28. That is, the stop ring 10 extends on a plane orthogonal to the axis of the inclined guide surface 28 with its axis aligned with the axis of the inclined guide surface 28. In other words, the stop ring 10 extends on the horizontal plane. Will exist.

By further downward movement of the plurality of leg pieces 20, the tips 2002 of the leg pieces 20 are displaced radially outward of the inclined guide surface 28, and the plurality of leg pieces 20 are moved by the inclined guide surface 28 to the radius of the inclined guide surface 28. Elastically deforms outward in the direction.
Since the stop ring 10 is pressed downward by the tips 2002 of the plurality of leg pieces 20 and moved downward, the stop ring 10 is expanded in diameter by the inclined guide surface 28 as it moves downward while maintaining a horizontal state. Go. That is, although the stop ring 10 is expanded in diameter by the inclined guide surface 28, the tips 2002 of the plurality of leg pieces 20 are also expanded inward in the radial direction of the inclined guide surface 28. The movement is made smoothly and reliably.
As shown in FIG. 4, when the plurality of leg pieces 20 are positioned at the lower limit position P5, the stop ring 10 passes through the outer peripheral surface 1202 of the work 12 and reaches the stop ring mounting groove 16, and the stop ring 10 is reduced in diameter due to its elasticity. Then, it is mounted in the stop ring mounting groove 16.
In the present embodiment, the moving means 26 that moves the plurality of leg pieces 20 in the direction of separating and approaching each other on the axis center by matching the axis centers of the plurality of leg pieces 20 and the axis of the inclined guide surface 28 is the leg piece. The actuator 34 is used.

When the stop ring 10 is mounted in the stop ring mounting groove 16, the plurality of leg pieces 20 return from the lower limit position P5 to the upper limit position P4, and the guide member 22 returns from the contact position P3 to the standby position P2.
The workpiece 12 having the stop ring 10 mounted in the stop ring mounting groove 16 is moved to the downstream position of the workpiece transfer path by the first robot arm R1, and the next workpiece 12 to which the stop ring 10 is to be mounted is the first robot. The arm R1 is moved to the mounting position P1, and thereafter the same operation is repeated, and the operation of mounting the stop ring 10 in the stop ring mounting groove 16 of the workpiece 12 is performed repeatedly.

According to the present embodiment, due to the downward movement of the plurality of leg pieces 20, the tips 2002 of the plurality of leg pieces 20 are displaced outwardly in the radial direction of the inclined guide surface 28 by the inclined guide surface 28, and stop. The ring 10 is moved downward by the plurality of leg pieces 20 and expanded in diameter by the inclined guide surface 28.
That is, the stop ring 10 whose diameter is expanded can be reliably pressed and moved by the tips 2002 of the plurality of leg pieces 20.
Further, by the downward movement of the plurality of leg pieces 20, the tips 2002 of the plurality of leg pieces 20 move on the outer peripheral surface 1202 of the workpiece 12, and the stop ring 10 is moved to the workpiece 12 by the tips 2002 of the plurality of leg pieces 20. The outer peripheral surface 1202 can be reliably pressed and moved.
Therefore, it is advantageous in automatically mounting the stop ring 10 in the stop ring mounting groove 16 of the outer peripheral surface 1202 of the workpiece 12.

In the present embodiment, since the guide pin 29 that can be attached to and detached from the hole 1204 of the workpiece 12 is provided at the end of the guide member 22 on the large-diameter outer peripheral surface 2804 side, the guide member 22 is lowered from the standby position P2. When the guide pin 29 is inserted into the hole 1204 of the workpiece 12 when approaching the workpiece 12, the axis center of the inclined guide surface 28 and the axis center of the outer peripheral surface 1202 of the workpiece 12 are shifted. Even if they are automatically aligned, their axes are aligned.
Therefore, it is advantageous in automatically and smoothly mounting the stop ring 10 in the stop ring mounting groove 16.

Further, in the present embodiment, since the plurality of leg pieces 20 have a uniform shape with each other, a plurality of locations spaced in the circumferential direction of the stop ring 10 can be pressed with equal force by the leg pieces 20, This is advantageous in moving the ring 10 on the inclined guide surface 28 in a stable state.
In addition, since the protrusions 2004 are provided at the tips 2002 of the plurality of leg pieces 20, when the plurality of leg pieces 20 are expanded in diameter by the inclined guide surface 28, they are inclined with respect to the intermediate portion in the longitudinal direction of the leg pieces 20. It is advantageous for preventing interference with the guide surface 28 and moving the stop ring 10 in a stable state, and also advantageous for moving the stop ring 10 on the outer peripheral surface 1202 of the work 12 having a uniform outer diameter. .

In the present embodiment, the guide member 22 and the workpiece 12 that have been positioned are stationary and the plurality of leg pieces 20 are lowered. However, the plurality of leg pieces 20 are stationary and the positioning is performed. The guide member 22 and the workpiece 12 thus formed may be raised together so that the stop ring 10 is mounted in the stop ring mounting groove 16. Alternatively, the plurality of leg pieces 20 may be lowered and the positioned guide member 22 and the workpiece 12 may be raised together to mount the stop ring 10 in the stop ring mounting groove 16.
In addition, it is optional that only the operation of placing the stop ring 10 on the inclined guide surface 28 is performed manually and the remaining operations are performed automatically.
In addition, when the stop ring 10 has magnetism, a magnetic force is applied to the tip portions of the plurality of leg pieces 20, and the stop ring 10 is attracted to the tip end 2002 of the leg pieces 20 by the supply means of the stop ring 10. In such a configuration, the axial centers of the plurality of leg pieces 20, the axial center of the guide member 22, and the axial center of the workpiece 12 are arranged in the same straight line extending in the horizontal direction, or the present invention is implemented. In this configuration, the work 12, the guide member 22, and the plurality of leg pieces 20 are arranged in reverse order, and the stop ring 10 can be mounted.

In the present embodiment, the case where the removable guide pin 29 is provided in the hole 1204 of the workpiece 12 has been described, but the guide pin 29 may be omitted. That is, when the hole 1204 is not formed in the workpiece 12, the guide member 22 causes the axis of the inclined guide surface 28 and the axis of the outer peripheral surface 1202 of the workpiece 12 to coincide with each other at the contact position P3. It is only necessary to place the lower end surface on the upper end surface of the workpiece 12. When the stop ring 10 is placed on the inclined guide surface 28 and the plurality of leg pieces 20 descend from the upper limit position P4, the tips 2002 of the plurality of leg pieces 20 come into contact with the inclined guide surface 28, and a plurality of circumferential pieces are arranged. Since the guide member 22 is pressed to the work 12 side from the place, the guide member 22 is pressed by the plurality of leg pieces 22 in a stable state. In this case, the support member 3002 at the tip of the guide member actuator 30 is configured to hold the guide member 22 from between the plurality of leg pieces 20, and after the stop ring 10 is mounted in the stop ring mounting groove 16, The guide member 22 may be held by the support member 3002 from between the plurality of leg pieces 20 before the leg piece 20 rises from the lower limit position P5.
Further, in the present embodiment, the case where the mounted member is the stop ring 10 has been described. However, the mounted member is also applicable to other members that have an annular shape and can be elastically deformed in the radial direction, such as an O-ring.
