W _N together with the wire diameter, the length and the color of the coating. Standards such as the dimensions of the terminals crimped on both ends and whether they are male or female are different. Conventional terminal crimping has adopted a one-by-one product number system in which one type of terminal is crimped by one terminal crimping machine. However, this method requires a large number of terminal crimping machines, requires not only a vast space for installation, but also has one terminal from each of the lot-produced wires w ₁ group, w ₂ group ... w _N group.

The descending distance of the crimper 12 ₁ is set in advance so as to obtain the optimum crimping condition by controlling the rotation amount of the screw shaft 15 in accordance with the standard of the terminal t ₁ . In this manner, a pair of crimper 12 and anvil 13 respectively corresponding to the order of the terminals t ₁ , t _2, ... Arranged and fixed to the tape a having different terminals are selected and used.

As is apparent from FIG. 20, the terminal crimping device b is provided with a plurality of pairs of crimpers 12 and anvils 13 corresponding to different terminals t ₁ , t _2, ... Since a terminal feed mechanism for each type as described above is not required and one ram 11 is sufficient for the press, it is possible to reduce the size and space of the device.

It is connected to the upper end of 44 through a bearing member 145.
146 is a servo motor, and its motor shaft 147 is connected to the input shaft 149 of the gearbox 143 via the coupling 148. Reference numeral 150 is a column that supports the mounting substrate 151 of the terminal feeding device D ₃ .

In the terminal feeding device D ₃ , the terminal t of the terminal t which is cut and separated by the frame feeding of the lateral chain terminal F has its terminal axis orthogonal to the terminal clamp 52. Therefore,
The terminal chuck 78 'of the direction changing device G is sandwiched by a pair of upper and lower gripping claws 80', 80 ', and the servomotor 146 is driven to rotate the turntable 141 by 90 ° in the counterclockwise direction in FIG. As a result, the terminal shaft coincides with that of the terminal clamp 52 as shown in FIG. 11, so that the terminal clamp can be held and transported (see FIG. 4B).

Next, the multi-part number crimping of terminals will be described.

As described with reference to FIG. 9, the terminal t ₁ (or t ₂ ) of the vertical chained terminal E fed by the terminal feeding device D ₁ (or D ₂ ) remains in the same posture after cutting and separating. It is clamped by the terminal clamp 52. Further, the terminal t of the lateral chain terminal F sent by the terminal feeding device D ₃ (or D ₄ ).
_As described with reference to FIGS. 10 to 12, ₃ (or t ₄ ) is once clamped by the terminal chuck 78 ′ of the direction changing means G after cutting and separating, and the terminal shaft is rotated by 90 ° of the turntable 141. After adjusting to the terminal clamp 52, the terminal chuck 78 'is transferred to the terminal clamp 52.

As described above, the terminals t clamped by the terminal clamp 52 in an arbitrary array are intermittently moved to the terminal delivery device C side by the rotation of the sprocket 50. And
For example, the terminal clamp 52 gripping the terminal t ₁ reaches the terminating operation post 65 ₁ . Here, the terminal transfer device C
Of the terminal chuck 78 ₁ is moved forward by the front-back positioning mechanism 90, and the terminal t _{1 is} attached to the pair of upper and lower gripping claws 80.
After gripping the electric contact portion 4 of FIG. 3, the movable arm 54 is opened by the cylinder 67 of FIG. 3 to release the terminal clamp 52.
At the time of transfer to the terminal chuck 78 ₁ , if necessary, the height is finely adjusted by the above-mentioned vertical positioning mechanism 103.

Then, by rotating the turntable 76 clockwise by 90 ° by the operation of the servo motor 72 shown in FIG. 5, the terminal t ₁ faces the multi-product number terminal crimping device A and is ready for crimping ( FIG. 22B). The terminal crimping by the multi-part number terminal crimping machine A is as described above, and the description thereof will be omitted.

The turntable 76 in the terminal transfer device C
90 ° rotation causes the next terminal chuck 78 ₂ (see FIG. 6) to move to the operating post 65 ₁ and the next terminal clamp 52.
To face. In this way, terminals in an arbitrary array can be sequentially and continuously crimped.

Terminal feed device D shown in FIGS. 10 to 12.
_In the direction changing means G of ₃ , the turntable 141 supporting the terminal chuck 78 'simply rotates by 90 °. Therefore, when the length of the terminal t of the lateral chain terminal F is shorter or longer than that of the standard product, as shown in FIG.
The base plate portion 5a of the barrel 5c for the insulating cover is displaced from the normal position between the terminal receiving seat 53a and the terminal pressing piece 54a. Therefore, the terminal clamps 52 cannot be properly clamped, and the entire terminal feeding device D ₃ must be moved with respect to the random transport device B, which takes time to set up and is inconvenient. Figure 1
The direction changing means G'shown in FIG. 4 solves such a problem, and after the terminal chuck 78 'is rotated by 90 °, it is advanced and retracted toward the terminal clamp 52 so as to correspond to the length of the terminal t. . In FIG. 14, devices other than the direction changing means G ′ are the same as those in FIG.

As a result, the slider 164 moves forward and backward in parallel with the horizontal chain terminal F by the operation of the air cylinder 173.

The plate cam 175 is arranged on the slide base plate 171 in parallel with the rail 172 so as to face the mounting block 169, and has a cam groove 176 with which the cam follower 168 engages. This cam groove 176 is shown in FIG.

A sloped guide path 176b that slopes away from the rail, and a straight exit path 176c that extends parallel to the rail 172 from the sloped guide path 176b.
It consists of and.

Next, the operation of the direction changing means G'will be described. In FIG. 15 (A) and FIG. 16, the terminal t that has been cut and separated from the lateral chain-like terminal F is connected to the terminal chuck 78 '.
After grasping with the grasping claws 80 ', 80' of the air cylinder 17,
The third piston 173a is extended. Then, the slider 16
4 is guided by the rail 172 and advances toward the terminal clamp 52 side. At the beginning, the cam follower 168 of the shaft foot 167
Is located in the straight introduction path 176a of the cam groove 176,
The shaft 163, that is, the terminal chuck 78 'and the turntable 161 go straight.

Next, the cam follower 168 moves the cam groove 17
6, when the shaft 163 starts rotating in the counterclockwise direction in FIG. 16, the shaft 163 is rotated 90 ° from the initial position at the end of the shaft guide 176b. Accordingly, FIG. 15 (B) and FIG.
As shown in FIG.

In this state, when the piston rod 173a is further extended, the cam follower 168 is located in the straight outlet passage 176c of the cam groove 176, so that the terminal chuck 78 'advances straight in the posture in which it is rotated by 90 °. That is, in the range of the length of the straight outlet path 176c, the terminal chuck 78 'faces the terminal clamp 52 and moves back and forth in parallel therewith.

According to the direction changing means G ', the distance between the terminal chuck 78' and the terminal clamp 52 can be freely changed after the terminal chuck 78 'is rotated by 90 °, so that the terminal clamp 52 can be adjusted in accordance with the length of the terminal t. It can be easily adjusted to the normal position and, as in the case of the turning means G, the entire movement of the terminal feeding device D ₃ is unnecessary.
