As shown in FIG. 1, the cylinder body 17 of the cylinder 15 is provided with a position sensor 19 for detecting the position of the piston 18. That is, in this case, a magnet is attached to the piston 18, and the sensor 19 serves as a magnetic sensor that detects the magnetism of the piston 18 and detects the position of the piston 18. In addition,
In FIG. 2, 20 is a holding rod that holds the frame body 7, and is connected to the reciprocating mechanism (not shown).

A packing detection sensor 6 is attached to this apparatus. This sensor 6 is an optical fiber type sensor in the example shown in FIG. 2 and its tip detection section 22 is shown in FIG. As shown, it is provided on the packing-corresponding portion 23 of the distal end surface 3a of the insert 3. That is, the connector housing portion 24 is provided on the vertical wall 7b of the frame body 7, and the optical fiber portion 25 extends from the tip detecting portion 22 to the insert body 3, the horizontal wall 7a of the frame body 7, the vertical wall 7b of the frame body 7. When the packing 4 is connected to the external detection device via the connector housing portion 24 and the protrusion 8 is externally fitted, the fact is detected. The sensor 6 is a reflection type in the embodiment.

Next, a method of assembling the packing 4 into the connector housing 1 with the packing assembling apparatus configured as described above will be described.

First, as shown in FIG. 5 (1), after the insert body 3 is positioned above the packing 4 placed on the placing surface 26, as shown in FIG. 5 (II), the packing 4 hole portion is formed. The insert 3 is lowered along the axis of 27, the protrusion 8 is inserted into the hole 27, and the packing 4 is fitted onto the protrusion 8. Then, in this state, the insert body 3 holding the packing 4 is positioned above the connector housing 1 held by the connector housing holder (not shown) so that the axis of the connector housing hole 28 becomes the vertical axis. It In this case, only the insert 3 may be moved, only the connector housing holder may be moved, or the insert 3 and the connector housing holder may be moved.

Thereafter, the insert 3 is lowered along the axial direction of the connector housing hole 28 to insert the insert 3 into the hole 28 as shown in FIG. 5 (III). The packing detection sensor 6 checks whether or not the packing 4 is fitted onto the protruding portion 8. That is, when the insert body 3 does not have the packing 4, it returns to FIG. 5 (I) again and, as shown in FIG.
Is held by the insert body 3.

Then, from the state shown in FIG. 5 (III), the insert body 3 is further lowered along the axial direction, and as shown in FIG. 5 (IV), one packing 4 is inserted from the bottom surface 28a of the hole 28. Stop by leaving a thick portion. Thereafter, the piston rod 16 of the cylinder 15 is extended in the direction of the arrow B (see FIG. 1), and the cross tooth-shaped pressing portion 13 of the pressing body 5 is projected from the tip surface 3a, as shown in FIG. 5 (V). In this manner, the packing 4 is pressed downward by the pressing portion 13 and pushed down to the connector housing hole bottom surface 28a, and then the piston 18 of the cylinder 15 is made free in this state. In this case, as shown in FIG. 6, when the two packings 4, 4 are inserted into the hole 28, the pushing body 5 is pushed as indicated by the arrow due to the elastic expansion of the two packings 4, 4. When the piston 18 is lifted, the position of the piston 18 is detected by the sensor 19 (see FIG. 1), and the two packings 4, 4
You can see that it contains 4. Further, as shown in FIG. 5 (V), if only one packing 4 is contained, the piston 18
The piston 18 retains its position even if the
It can be detected that the sensor 19 has not risen, and one packing 4 is contained in the hole 28.

After that, as shown in FIGS. 5 (VI) and 5 (VII), the pressing portion 13 of the pressing body 5 is housed in the insert body 3, and the insert body 3 is raised to raise the connector housing hole. Part 28
The packing 4 can be assembled in the hole 28 by taking it out. When the insert 3 is raised, the packing 4
The packing detection sensor 6 detects whether or not the assembly will rise together with the insertion body 3. That is, when the packing 4 is still locked to the protruding portion 8, the packing 4 can be detected by the sensor 6. Therefore, when the packing 4 tries to rise together with the insert 3, the packing 4 may be pushed in again.

Therefore, according to the above-described device, it is detected that the insert body 3 holds the packing 4 immediately before the packing 4 is inserted into the connector housing hole 28, and the packing 4 is inserted immediately after the insertion is completed. It can be detected that the body 3 is not held, and it can be confirmed that the packing 4 has been reliably assembled in the connector housing hole 28.

It should be noted that the present invention is not limited to the above-described embodiments, and the design can be freely changed without departing from the gist of the present invention.
As the sensor 6, it is only necessary to detect the presence or absence of the packing 4, so various sensors can be used.
The cylinder that reciprocates can be either hydraulic or pneumatic.

[Effect of device]

Since the present invention is configured as described above, it has the following effects.

Immediately before the insertion of the insert 3 into the connector housing hole 28, it is possible to detect that the packing 4 is held by the insert 3, and the packing 4 is pushed by the connector 5 into the connector housing hole. Immediately after the insertion body 3 is pulled out from the connector housing hole portion 28 after being pushed into the bottom surface 28a of the 28, it is possible to detect that the packing 4 is stuck to the insertion body 3 and is not pulled out. The packing 4 can be reliably and automatically incorporated into the connector housing 1, and the working efficiency can be greatly improved.
