[0014] In the figure, 4 0 at reversing mechanism, when fitting a ₁ insulator from the belt conveyor (not shown) _{(a 2)} is sent to the table 41 mounting to the cylindrical portion 1 under mounting table 41 is not shown The drive unit rotates the support shaft 42 by 180 ° in the direction (clockwise) indicated by the arrow A around the support shaft 42, and inverts the insulator a ₁ (a ₂ ) on the mounting table 41 in the direction of the arrow B, and It acts so as to be thrown into the opening 15 of 14.

In the figure, S ₁ , S ₁ and S ₂ , S ₂ are sensors composed of photoelectric elements. Among them, the sensors S ₁ , S ₁ are provided so that the detection light beam passes through the opening 15 of the grip portion 14. On the other hand, the sensors S ₂ and S ₂ are provided such that the detection light beam is separated from the upper surface of the grip portion 14 by a predetermined distance upward and is parallel to the upper surface.

Next, the operation of the present embodiment will be described. First, before fitting a ₁ insulators from reversing Organization 40 _{(a 2)} is inserted in the grip portion 14, the distance between the grip portion 14 and the disk 22 as indicated by the solid line in FIG. 1, insulator bracket a ₁
(A ₂ ) is gripped by the gripper 14, and in this state, the protrusion 2
The cylinder 11 is driven so that the column 1a is positioned at the tip (lower end) of the mounting portion 2 when the column 3a is inserted into the gap A.
Adjust the height position of 3. This adjustment is performed by the insulator a ₁
Since the size of (a ₂ ) is constant, insulator a
_As long as the type of ₁ (a ₂ ) is not changed, the initial setting can be used.

Also, when the mounting position of the sensors S ₁ and S _{2 is at} the position of the insulator a ₁ (a ₂ ) at the solid line in FIG.
Further, as shown by the two-dot chain line, adjustment is made so that the gap A is turned off when the gap A is not inserted into the convex portion 23a. This adjustment, like the position adjustment of the grip portion 14 mentioned above, suffice initially set as long as the type of insulator fitting a _{1 (a 2)} is not changed.

Now, the gripper 14 has an insulator a
Before ₁ (a ₂ ) is input, both sensors S ₁ , S ₁ and S ₂ , S ₂ are kept in the ON state. Then, when the insulator fitting a ₁ (a ₂ ) is put into the holding portion 14 from the reversing mechanism 40, the sensors S ₁ and S ₁ are turned off. In addition,
Initially, the direction of the convex portion 23a is set to a direction in which the insulator fitting a ₁ (a ₂ ) has a predetermined posture.

In the above-mentioned loading, the insulator fitting a ₁ (a
If the gap A of the mounting portion 2 of ₂₎ is inserted into Ding Dototsu portion 23a, since the posture of the insulator fitting a _{1 (a 2)} is in a predetermined posture, no more positioning operation is not required .
Therefore, the operation of the rotating mechanism 30 is not performed, and the gripping mechanism 1 is not operated.
The column 13 of 0 rises to an unillustrated automatic handling device. When the insulator a ₁ (a ₂ ) is handled by the automatic handling device, the support 1
3 is lowered to the initial set position, and the next insulator a
_{It is in} a standby state for inputting ₁ (a ₂ ).

However, in the above-described loading, the insulator a ₁ (a ₂ ) is often in the state shown by the two-dot chain line in FIG. That is, the lower end of the mounting portion 2 of the insulator a ₁ (a ₂ ) is located on the projection 23a. Accordingly, the sensors S ₂ and S ₂ are turned off, and the cylinder 32 is reciprocated based on the OFF signal to reciprocate the rotary shaft 21 by 180 ° via the rack 33 and the pinion 31. Since the convex portion 23a is also reciprocated by the reciprocating rotation of the rotating shaft 21, the gap A can be inserted into the convex portion 23a. When the gap A is inserted into the convex portion 23a, the insulator fitting _a 1 _{(a 2)} is lowered to the solid line position in FIG. 1, sensor _S 2, _{S 2} is such an ON Runode, protrusions based on this ON signal The cylinder 32 is stopped at a position where the direction of 23a is a predetermined direction. Thereby, the insulator fitting a
₁ (a ₂ ) is set to a predetermined posture. Thereafter, the gripping mechanism 10 is operated as described above, and the fitting a ₁ (a ₂ )
To the handling device side.

As described above, in the apparatus of this embodiment, since the convex portion 23a of the positioning table 20 is rotated to insert the convex portion 23a into the gap A, positioning can be performed with a simple configuration. . Also, the sensors S ₁ , S ₁ and S ₂ , S
₂ , it is possible to detect the presence or absence of the insulator fitting a ₁ (a ₂ ) and the state of insertion of the projection 23 into the gap A, so that automation can be achieved based on the detection signal.

In the description of the operation of the above embodiment, the positioning table 20 is of the type having the convex portion 23a.
When the positioning table 20 is of a type having the concave portion 23b,
The mounting portion 2 is inserted into the concave portion 23b and positioned.
