Dices 55 and 56 are provided above and below the inside of 3a so as to face each other. The lower die 56 is attached to a ram 63 (not shown) in the cylinder 54, and can be moved up and down by hydraulic pressure sent from a pump 58 when the motor 57 rotates. The sleeve 60 and the electric wire W can be crimped. Dice 5
The compression center position of 5, 56 is set to be slightly higher than the grip center position of the grip members 9, 10 of the grip machine 6. That is, the position of the upper die 55 is arranged higher than that of the upper gripping member 9 so that the electric wire W is not obstructed when it is received from the side. Therefore, during compression operation, the lower die 56 is positioned above the lower gripping member 10. Although it also rises upward, at this time, the spring 51 is compressed and aligned. In FIG. 14, reference numeral 59 is a sleeve cover made of elastic synthetic resin, and together with the sleeve 60, the die 5

The branch line W1 is installed in advance and the opening 60 for receiving the electric wire
A is set to face the peeling machine 4 side. Reference numeral 61 denotes a suspending arm, which is used when suspending the device 1 with a manipulator or the like.

The automatic connection device 1 of this embodiment is, for example,
It is hung on the tip of the manipulator and brought close to the overhead wire W that is energized. Between the pair of dies 55 and 56 of the compressor 5, the crimping metal sleeve 60 to which the branch line W1 is attached in advance is provided.
To hold. The apparatus 1 is brought to a predetermined position of the overhead wire W with the compressor 5 and the gripper 6 open, and the wire W is inserted between the gripping members 9 and 10 of the gripper 6 from the side. Then, first, the gripping machine 6 is caused to perform a wire gripping operation, and in conjunction with this, the hook member 13 of the hook device 7 is erected, and the wire W is hooked. With this, the entire device 1 is stably hooked on the electric wire W (FIG. 3A). Next, the moving table 3 is moved in one direction (rightward in FIG. 3) by a predetermined distance to bring the peeling machine 4 closer to the electric wire W, and the electric wire W is rotated by the rotor 2 of the peeling machine 4.
1 (FIG. 3B). The rotor 21 is the main body 3 beforehand.
1 and the lid 32 are opened (FIG. 7, phantom line), and set in the housing 20 with the open portion facing the electric wire W side.
The brush 40 is pushed inward in the radial direction of the rotor 21 and held by the latch mechanism 43 so as not to come into contact with the outer circumference of the electric wire W (FIGS. 10 and 12A). Then, when the motor 27 is started, the output shaft 45, the sprocket 29, the chain 30, the sprocket 25, the drive shaft 24, and the gear 26 sequentially rotate. In FIG. 7, when the drive gear 26 rotates clockwise, the main body 31 of the rotor 21 rotates along the inner circumference of the peripheral wall 20c of the housing 20 together with the gear piece 34 meshing with the drive gear 26, and the lid 32 opens.
Is drawn into the holding space 23 from the above, and at the same time, the lid 32 is pushed by the peripheral wall 20c and joined to the main body 31, and the electric wire W is held inside the rotor 21. Since the main body 31 and the lid 32 are attracted to each other by the magnet 36, the lid 32
Even when is at the position of the opening 22, the gap with the main body 31 does not open. When the rotor 21 further rotates, the cutter 39 attached to the lid 32 bites into the coating C of the electric wire W,
By rotating the wire C once around the electric wire W, the coating C is peeled off over a predetermined width. The stripped off piece C1 has a substantially C-shaped cross section and is attached so as to grip the outside of the lid body 32 due to its elasticity (FIG. 10). If the rotor 21 continues to rotate in this state, the fragment C1 is drawn between the rotor 21 and the housing 20 and becomes inoperable.
Therefore, when the rotor 21 rotates, the protrusion 20d is moved to the lid 3
The fragment C1 of the coating C adhering to the outer periphery of the lid 32 is forcibly scraped off by relatively moving in the vicinity of the outer periphery of 2. During the rotation of the rotor 21 so far, the roller 50 is
The inner circumference of the peripheral wall 20c of No. 0 rolls in one direction, but it slips against the trip shaft 48, and the trip shaft 48 is stationary at the position shown in FIG. 46
Engages with the engaging shaft 45 of the brush 40 to hold the brush 40 in the retracted position. When the rotor 21 has rotated a predetermined number of times to complete the stripping of the coating C, the motor 27 automatically reverses rotation and the rotor 21 rotates in the opposite direction by a predetermined angle. This reversal causes the roller 50 to rotate in the opposite direction, but this time the one-way clutch 49 is connected to the shaft 48 and the shaft 4
8 rotates together. As shown in FIG. 12 (B), the shaft 4
When 8 rotates, the flat portion 48a pushes the latch shaft 46 in the axial direction, and when the flat shaft 48a rotates 90 °, the engagement stepped portion 46b is disengaged from the engagement recess 45b, and the brush 40 is pushed out by the spring 42 to cover it. It is pressed against the surface of the stripped electric wire W. After the brush 40 reaches this state, the motor 27 reverses and the rotor 21 rotates a predetermined number of times in the opposite direction, during which the surface of the electric wire W is polished by the brush 40. When the polishing of the electric wire W is completed, the motor 27 is stopped with the lid 32 at the position of the opening 22 of the housing 20. After stripping off the coating C of the electric wire W with a predetermined width, the moving table 3 is moved in the other direction (left in FIG. 3, right in FIG. 7), the peeling machine 4 is separated from the electric wire W, and the compressor 5 To the electric wire W. At this time, the space between the lid 32 and the body 31 is opened against the magnetic force (FIG. 7, phantom line). The motor 27 has an encoder, and the rotation direction and the number of rotations thereof are controlled. When the movable table 3 moves a predetermined distance, the opening 60a of the sleeve 60 held between the dies 55 and 56 of the compressor 5 is opened.
The electric wire W is received (FIG. 3 (C)). Then, the electric wire W, the branch line W1, and the sleeve 60 are integrally crimped by the compression operation of the dies 55 and 56. At this time, the die 56 rises to a position where the electric wire W is pushed up, but the spring 51 is compressed via the pedestal 52, and the compressor 5 itself descends with respect to the frame 2. As a result, between the gripping members of the gripping machine 6. There is no vertical difference between the axis of a certain wire W and the axis of the wire W between the dies 55 and 56. During the compression operation, the sleeve cover 59 is closed and engaged to cover the sleeve 60. After the crimping is completed, the dies 55 and 56 are opened, and the electric wire W is released from the gripping machine 6,
The hook member 13 is turned over, the device 1 is removed from the electric wire W, and the connection work of the branch line W1 is completed. All the operations up to this point are automatically performed.

[0022]

As described above, in the present invention, the movable base 3 is provided on the frame 2 which can be hooked on the overhead wire W so as to be reciprocally movable in a direction substantially orthogonal to the axis of the wire W. The motor 16 drives the electric wire W so that the electric wire W is moved closer to the electric wire W on the moving table 3 by a predetermined distance in one direction, and the electric wire W is received by the rotation of the cutter 39.
