The clamp 18 on the right side of the crimping device 14 moves to the left to hold the wire 6 in the vicinity of the connector 3 and hold the wire 6 at a portion slightly leftward from the connector 3. The clamp 16 is opened to release the wire 6 in that part. FIG. 5 shows the next length measuring step. The right clamp 18 moves right while holding the wire 6 to further pull out the wire 6, and measures the length of the harness. The left clamp 16 also moves to the right with the right clamp 18 and the wire 6 and then closes to hold the wire 6. For the length measurement, the right clamp 18 itself may be provided with a measuring function to measure the distance traveled, or the wire stand 10

A continuity check may be performed before this discharge. In this way, one 1-N harness 8
Is discharged, one step of its manufacturing is completed, and the state of the start is returned. Although another clamp 20 is provided further to the left of the left clamp 16, it is not used when the 1-N harness 8 is manufactured. That is, it is not necessary when the 1-N harness is manufactured by the same method as the conventional method by using the device for manufacturing the 1-N harness as a base. Then this first

FIG. 12 further illustrates the next reversing or reverse rotation step, in which the clamp 18 on the right side moves left to slacken the wire and then rotates 180 ° again. As a result, the wire 6 can be twisted, but this is because the apparent directions of the connectors 3 and 5 are the same as those of the 1-N harness and the directions of the connectors 3 and 5 of the harness 9 are aligned with the path for the continuity check. Therefore, if the continuity check is unnecessary, the slack formation and the inversion (reverse rotation) are not necessary, and the discharge may be performed as it is. At this time, the left pressure welding device

The configuration of the harness manufacturing apparatus according to this embodiment is basically the same as that of the both-end automatic pressure welding machine described in JP-A-61-88476.
This corresponds to a device based on a device for manufacturing N harness, in which the vertical relationship of the left pressure welding device 12, that is, the positional relationship between the punch 12a and the die 12b is reversed. FIG. 18 shows the start state, in which the connector 3 is pressure-connected to the tip of the wire 6 pulled out from the wire stand 10 for supplying the wire 6 by the pressure-bonding device 12 on the left side, and then on the right side of the pressure-bonding device 14 on the right side. The clamp 18 located on one side moves to the left to hold the wire 6 in the vicinity of the connector 3, and the clamp 16 holding the wire 6 opens at a portion slightly leftward from the connector 3 to open. The wire 6 in that portion is released. FIG. 19 shows a length measuring step. The right clamp 18 moves right while holding the wire 6 to further pull out the wire 6, and measures the length of the harness. The left clamp 16 also moves to the right with the right clamp 18 and the wire 6 and then closes to hold the wire 6.
FIG. 20 shows the steps of crimping and cutting, in which the wire 6 is cut and the crimping device 14 on the right side
The connector 5 is pressed against the other end of the connector, that is, the end where the connector has not been pressed yet. Next, the left clamp 16 is moved or retracted to the left, and the next connector 3 ′ is crimped to the cut end of the wire 6 by the left crimping device 12. In this way, one 1-1 harness 9 is completed, and the connector 3'on the tip side of the next harness is pressed. FIG. 21 shows a harness discharging step, in which both the left and right press-connecting devices 12 and 14 are opened to release the connectors 3 and 5, and the harness 9 is discharged. A continuity check may be performed before this discharge. In this way
One 1-1 harness 9 is discharged, one manufacturing process is completed, and the state returns to the start state. It should be noted that another clamp 20 is provided further to the left of the left clamp 16, but this is not used when the 1-1 harness 9 is manufactured. That is, it is not necessary when the 1-1 harness is manufactured by the same method as the conventional method by using the device for manufacturing the 1-1 harness as a base. Next, a mode of manufacturing a 1-N harness based on the 1-1 harness manufacturing apparatus of the second embodiment will be described with reference to FIGS. 22 to 31. Figure 2

While the two clamps 16 and 18 are both rotated about the wire 6 by 180 °, the wire 6 is cut, and the pressure welding device 14 on the right side is the other end of the wire 6, that is, the connector to which the connector is not yet pressure welded. The connector 5 is pressed against the end portion. At this time, since the wire 6 is rotated by 180 °, the connector 5 press-contacted here has the same direction as the connector 3 press-contacted to the tip. Then the left clamp 16 is moved or retracted to the left, and the next connector 3 ′ is crimped to the cut end of the wire 6 by the left crimping device 12.
In this way, the connectors 3 and 5 in the same direction are pressed to both ends to complete the 1-N harness 8, and the connector 3'on the tip side of the next harness is pressed. FIG. 26 shows the step of the next reversal, that is, the reverse rotation,
The right clamp 18 moves left to slacken the wire and then rotates 180 ° again. As a result, the wire 6 can be twisted, but this causes the apparent orientation of the connectors 3 and 5 to be 1
This is because the connectors 3 and 5 of the harness 8 are oriented in the same path as that of the -1 harness for the continuity check. If the continuity check is unnecessary, the slack formation and the reversal (reverse rotation) are not necessary. , May be discharged as it is.
At this time, the left press-connecting device 12 is opened to free the connector 3'at the tip of the next harness, and the clamp 16 is rotated by 180 ° in the reverse direction to reverse the direction of the connector 3 '.

In a harness manufacturing apparatus for manufacturing a large number of wire harnesses by repeating the step of crimping a connector, the harness manufacturing apparatus arranges a punch and a die of the crimping apparatus on a lower side and an upper side, respectively, and punches of the other crimping apparatus. And the die are arranged on the upper side and the lower side, respectively 1-
1 is a device for manufacturing a harness, wherein another further clamp is arranged on the upstream side of the second clamp, and the wire group is placed at a position apart from the tip of the wire group after press-fitting the first connector. Before cutting the wire, the wire group is gripped by the further other clamp, and the first and second clamps are clamped to the wire group by the first and second clamps. 180 ° about the group transfer path with respect to the other clamps
Rotate, and then press-connect the second connector to 1-
A harness manufacturing apparatus characterized in that it is possible to selectively manufacture a 1-1 harness and a 1-N harness by being configured to manufacture an N harness.
