The rotation arm 13 is defined so that the angle between the position in the horizontal state shown by the solid line in FIG. 2 and the position in the vertical state shown by the two-dot chain line is substantially 90 degrees. . These rotating arms 13 and 13 are driven to rotate by a driving mechanism (not shown) that performs pneumatic driving, hydraulic driving, electric power driving, and the like, and when these rotating arms 13 and 13 approach each other, The electric wire W is sandwiched between the gripping blocks 14.

Each of the gripping blocks 14 is formed with a gripping concave portion 15 on a surface facing each other when approaching each other. As shown in FIG. 2, the holding recess 15 has a contact surface 15A at an angle α with respect to a perpendicular S perpendicular to the rotating arm 13 and a contact surface 15B at an angle β with the perpendicular S.

A is arranged so as to be parallel with a predetermined interval in the width direction of the holding block 14. Similarly, the gripping piece 16B is arranged corresponding to the gripping piece 16A. further,
The gripping blocks 14 are displaced by a predetermined distance in the rotation axis direction so that the other gripping pieces 16A, 16B1 can be inserted into the respective gaps of the gripping pieces 16A, 16B of one gripping block 14. I have. With such a configuration, the holding blocks 14 of each other are
The contact surface 15 is formed on the outer peripheral surface of the electric wire W by being closely overlapped.
A and 15B can be brought into contact with each other. FIG. 3A shows an open state in which the gripping blocks 14 and 14 are in a horizontal position, and FIG. 3B shows a state in which the rotating arm 13 is driven to rotate and the gripping blocks 14 approach each other, and 16A and 16B show a state where they overlap each other.

By the way, the transporting wire gripping clamp 10B
1 to 10B4, the transporting wire gripping clamp 10B1 located at the first position is configured such that the piston rod 32 protrudes from the reciprocating drive cylinder 31 to the maximum, and the wire W It is set so as to sandwich. That is, the electric wire W cut by the cut stripping portion 25 and attached with the terminal fittings by the first terminal crimping unit 24 is cut and stripped in a state of being sent out by a predetermined length. The transport wire gripping clamp 10B1 at the first position is arranged so as to be able to grip the front end (the terminal metal fitting is not mounted in this portion) of the drawn wire W. Here, the stroke of the piston rod 32 of the reciprocating drive cylinder 31 is set so as to correspond to the interval between the transporting electric wire clamps 10B1 to 10B4 as described above.

For this reason, the conveying wire gripping clamp 10B
On the 1-10B4 side, as shown in FIG. 6, the transporting wire clamp 10B1 located at the first position P1 transports the wire W to the second position P2 of the fixed wire gripping clamp 10A1, and moves to the first position P1. The reciprocating operation of returning is repeated. Similarly, the other electric wire gripping clamps 10B2 to 10B4 perform a reciprocating operation for the distance between the fixed electric wire gripping clamps 10A1 to 10A3 (the same as the distance between the conveying electric wire gripping clamps 10B1 to 10B4), and the movement in the transport direction x. The electric wire W located on the upstream side is transported to a position on the downstream side by one.

That is, when the first electric wire W1 is first placed at the first position P1, the transport electric wire gripping clamp 10B1 grips the electric wire W1 and moves to the second position P2. Next, the fixed-type electric wire gripping clamp 10 at the second position
A1 grips the electric wire W1 conveyed from the electric wire gripping clamp 10B1, and grips the electric wire gripping clamp 10B1.
Releases the grip of the electric wire W1 and returns to the first position P1 as shown by the arrow.

Then, the transporting wire gripping clamp 10B1 returning to the first position grips the second wire W2, and at the same time, the transporting wire transporting clamp 10B2 moves to the second position P2.
Is gripped. At this time, in the first position, the gripping clamp 25A of the cut and peeling portion 25 releases the gripping of the electric wire W2, and at the same time, the fixed electric wire gripping clamp 10A in the second position.
Numeral 1 releases the grip of the electric wire W1. After that, it moves in the transport direction.

As a result, the transport wire gripping clamp 10B
1 transfers the electric wire W2 to the fixed electric wire gripping clamp 10A1 at the second position P2, and the fixed electric wire gripping clamp 10A1
When gripping the electric wire W2 with the electric wire gripping clamp 1 for transport
0B1 releases the grip of the electric wire W2. At the same time, the transfer wire gripping clamp 10B2 grips the wire W1 held by the fixed wire gripping clamp 10A1 at the second position P2, and releases the wire W1 after the fixed wire gripping clamp 10A1 releases the wire W1. It is transported to the fixed-type electric wire gripping clamp 10A2 at the third position P3. In addition, the cutting peeling part 2
5 gripping clamp 25A and fixed electric wire gripping clamp 1
The release of gripping of the electric wire between 0A1 and 0A1 is set to be performed in synchronization.

Subsequently, at the same time, the transport wire gripping clamp 10B1 grips the third wire W3 at the first position P1, and the transport wire gripping clamp 10B2 grips the wire W2 at the second position P2. The wire holding clamp 10B3 holds the wire W1 at the third position P3. Next, the gripping clamp 25A, the fixed electric wire gripping clamps 10A1, 10A
2 releases the gripping of the electric wires W3, W2, W1, and then moves the conveying frame 30 in the conveying direction x, so that the respective electric wire gripping clamps 10B1, 10B2, 10B are moved.
B3 can advance one position of the electric wire to the downstream side in the transport direction. Thus, each fixed electric wire gripping clamp 1
The electric wire W can be conveyed to the transfer position shown in FIGS. 4 and 5 by relaying 0A1, 10A2, and 10A3.

In such a transport section 27, the second terminal crimping unit 28 is disposed beside the fixed electric wire holding clamp 10A3 at the fourth position P4, and is held by the fixed electric wire holding clamp 10A3. The terminal fitting is attached to the end of the electric wire W where the terminal fitting is not attached. In addition, an extraction wire gripping clamp 10C that receives the wire W can be located at the transfer position. This take-out wire holding clamp 1
0C is provided in the electric wire delivery unit 29 as the above-described electric wire extraction device.

Here, an electric wire gripping clamp 10C for extraction
The configuration of the electric wire sending section 29 including the same will be described. As shown in FIG. 4, FIG. 7, and FIG. 8, the take-out wire gripping clamp 10C has substantially the same configuration as the wire gripping clamp 10 described above. The difference from the electric wire gripping clamp 10 is that a rotating shaft 41 integrally provided at the lower end of the support block 11 is pivotally supported on the device base side, and the rotating shaft 4
1 can be rotated about a rotation axis. Also,
A first gear 42 is provided integrally with the rotating shaft 41. The first gear 42 is combined with the second gear 43 so as to mesh with the first gear 42. The second gear 43 is integrally provided with a rotating shaft 44, and the rotating shaft 44 is supported by a member on the base B side of the apparatus. This second gear 4
One end of a cam arm 45 is integrally fixed to the third rotating shaft 44 as an interlocking arm. A long guide hole 45A is formed along the longitudinal direction at an intermediate portion near the other end of the cam arm 45. A guide projection 30A protruding from a predetermined position at an end of the transport frame 30 is slidably fitted in the guide long hole 45A. Therefore, with the reciprocating operation of the transport frame 30, the cam arm 45 can be rotated in the clockwise direction and the counterclockwise direction in FIG. 7 while the guide projection 30A slides on the guide long hole 45A of the cam arm 45. It has become. With this rotation, the second gear 43 also rotates bidirectionally by a predetermined angle, and the first gear 42 meshing with the second gear 43
Is rotated in a direction opposite to that of the second gear 43. With the rotation of the first gear 42, the support block 11 moves between a position indicated by a chain line and a transfer position. As shown in FIG. 9, the rotation trajectory of the pair of gripping blocks 14, 14 in the state where the electric wire W is discharged into the electric wire tray T at the discharge position to the transfer position (receiving position) is the position of the side plate of the electric wire tray. It is set to pass outside.

Next, the operation and operation of the transporting section 27 and the electric wire sending section 29 having such a configuration will be described.

First, the front end of the electric wire W cut and cut by the cut and peeling portion 25 (this portion has no terminal fittings attached) is connected to the transfer electric wire gripping clamp 1 at the first position P1.
The pair of gripping blocks 14B is gripped between the pair of gripping blocks 14B. Here, the piston rod 3 of the reciprocating drive cylinder 31
The protrusion amount of No. 2 is maximum. Next, the transport frame 30 is moved by driving the reciprocating drive cylinder 31 so that the amount of protrusion of the piston rod 32 is minimized while the transport wire gripping clamp 10B1 grips the wire W. By this movement, the transport wire gripping clamp 10B1 is
It moves to the second position P2 while holding the electric wire W. Prior to the movement of the transfer wire gripping clamp 10B1, a pair of gripping blocks 1 of the fixed type wire gripping clamp 10A1 are provided.
Driving control is performed so that 4, 4 are opened.
Then, at the second position P2, the fixed electric wire gripping clamp 10A
1 is an electric wire W gripped by the transporting wire gripping clamp 10B1.
After that, the pair of gripping blocks 14, 14 of the transporting wire gripping clamp 10B1 is released, and the wire W is transferred to the fixed wire gripping clamp 10A1. At this time, the gripping blocks 14, 1 of the transport wire gripping clamp 10B1 are used.
4 is in a state of being opened in a horizontal state, so that it is at a position lower than the height of the electric wire W gripped by the fixed-type electric wire gripping clamp 10A1. For this reason, the transporting wire gripping clamp 10B1 can return to the first position P1 without being disturbed by the wires W during movement by maintaining this state.

Next, after the transport wire gripping clamp 10B1 transports the wire W to the fixed wire gripping clamp 10A1 and returns to the first position P1, the transporting wire gripping clamp 10B2 provided on the transport frame 30 is fixed. It moves to the second position P2 where the mold wire gripping clamp 10A1 is located.
The electric wire gripping clamp 10B2 is used for the electric wire W.
, The fixed-type electric wire holding clamp 10A1 releases the electric wire W and moves the holding blocks 14, 14 to a horizontal state.

Next, when the transport frame 30 is driven to move in the transport direction, the transport wire gripping clamp 10B2 moves to the third position P3 while gripping the wire W. Then, similarly, the electric wire W is delivered to the fixed electric wire gripping clamp 10A2. The electric wire W grasped by the fixed electric wire gripping clamp 10A2 is similarly transferred to the fixed electric wire gripping clamp 10A3 at the fourth position P4 by the transfer gripping clamp 10B3. The second terminal crimping unit 28 described above is arranged at the fourth position P4, and the terminal fitting is crimped to the end of the electric wire W. The wire W to which the terminal fitting is crimped is transported to the delivery position by the transport wire gripping clamp 10B4. At this time, the extraction wire gripping clamp 10C is
It moves to the delivery position in synchronization with the transporting wire gripping clamp 10B4. That is, the transport wire gripping clamp 10
When B4 moves to the delivery position, the transport frame 3
0 also moves in the same direction at the same time.
By pressing the cam arm 45, the drive gear 43 is rotationally driven to rotate the reversing gear 42 in the clockwise direction in FIG.
Will move to the delivery position. At this time, a pair of gripping blocks 1 of the extraction wire gripping clamp 10C.
4 and 14 are driven so as to be in a state where they are spread apart as shown in FIG.

Then, an electric wire gripping clamp 10C for removal
Is the transport wire gripping clamp 1 located at the delivery position
The electric wire W gripped at 0B4 is gripped. Thereafter, the transport wire gripping clamp 10B4 releases the wire W and moves toward the third position together with the transport frame 30. Since this movement also moves the guide projection 30A, the cam arm 45
Rotates clockwise in FIG. 9 to move the take-out wire gripping clamp 10C to the position indicated by the two-dot chain line in FIG. Then, the take-out electric wire holding clamp 10 </ b> C can drop the electric wire W to the electric wire tray T by opening the holding blocks 14, 14. Both ends of the electric wire W dropped onto the electric wire tray T become a finished product of a wire harness to which terminal fittings are attached by the first terminal crimping unit 24 and the second terminal crimping unit 28.

Although the automatic cutting and crimping device 20 to which the wire take-out device according to the present invention is applied has been described above, in the present embodiment, the wire feeder 29 as the wire take-out device is provided.
Since the cam arm is interlocked with the transport frame 30 via the synchronous arm 45, there is an advantage that a driving force for separately driving the electric wire feeding section 29 is not required. When the electric wire W is accommodated in the electric wire tray T, the electric wire W is securely accommodated without coming into contact with the electric wire tray T because the gripping blocks 14 of the electric wire gripping clamp 10C are in an open state. Can be. Further, in the present embodiment, the transport frame 30 is reciprocated at a predetermined swing width by using the gripping operation and the releasing operation of the transport gripping clamps 10B1 to 10B4 and the fixed-type wire gripping clamps 10A1 to 10A3. Can be achieved. Also,
In the present embodiment, since the guide rail 30B is provided so as to extend to the position where the connecting member 33 is provided in the transport frame 30, the piston rod 3 of the reciprocating drive cylinder is provided.
2, the guide rail 30B enables smooth sliding and improves the rigidity of the transport frame 30. Further, by arranging a plurality of transporting wire gripping clamps and a plurality of fixed type wire gripping clamps, the stroke of the piston rod 32 of the reciprocating drive cylinder 31 can be shortened, and in combination with the use of the guide rail 30B. In addition, it is possible to perform an agile operation without rattling. For this reason, it is possible to carry the electric wire at high speed and with high efficiency. In addition, the automatic cutting and pressing device 20
In each of the electric wire gripping clamps (10A1 to 10A3,
10B1 to 10B4, 10C) gripping block 1
4, one contact surface 15B located on the rotation center side and the perpendicular S
Is set to be larger than the angle between the other contact surface and the perpendicular. For this reason, the automatic cutting and pressing device 2
In the case of handling electric wires W having different diameters at 0, it is possible to suppress the center axis of the electric wires W from being shifted due to the different diameters. Further, when the electric wire W is gripped, it is possible to prevent the portion on the one contact surface 15B side from hitting the electric wire as the grip block 14 rotates.

Although the embodiment has been described above, the present invention is not limited to this, and various design changes accompanying the gist of the configuration are possible. For example, in the above-described embodiment, the electric wire sending section 29 is connected to the automatic cutting and pressing device 2
Although the example in which the wire take-out device is used in the case where the terminal fitting is attached to the wire end by applying to the example 0 has been described, it goes without saying that the wire take-out device according to the present invention can be applied to a device that performs another process. Further, as shown in FIG. 10, a hanging piece 30C is formed on the transport frame 30 side, and the hanging piece 30C is formed.
A guide hole 30D is formed in C along the up and down direction, and a projection 45B of the cam arm 45 is slidably engaged with the guide hole 30D, and a rotation shaft 45C provided integrally with the cam arm 45 is connected to the base B side. Even if the support block 11 of the electric wire gripping clamp 10C is integrally fixed to the rotating shaft 45C, the electric wire gripping clamp 10C is similarly operated. It is possible.

In addition, since a separate driving mechanism is not required, there is an effect that costs required for driving can be reduced.

According to the second aspect of the invention, when the take-out clamp supported on the base rotates, the locus of rotation of the pair of gripping blocks toward the receiving position is outside the side plate of the wire tray. Therefore, it is possible to prevent the holding block from hitting the wire tray, and it is possible to securely store the wires in the wire tray.
