Further, by controlling the high-pressure air supplied to the air cylinder 72, the slide body 73 is reciprocated in the vertical direction so that the operator receives the electric wires W ₁ and W ₂ drawn forward, and the electric wires W ₁ and W When stripping ₂ , the sensor main body 75 can be moved up and down between the elevated position where it is retracted upward and does not interfere with the electric wires W ₁ and W ₂ .

  As shown in FIG. 1, a control monitor 130 having a display unit 130A and driving control of the above-described components is installed above the strip mechanism 60A, and the above-described drive control of the components is performed by the control monitor 130. Is done.

Furthermore in the vicinity of the control monitor 130, among the different types of the pair of electric wires W _1, W _2, for example by inserting one of the wire W ₁ to the strip means 60 of the strip mechanism 60A, or the other of the wire W ₂ strips An LED lamp 131 is provided to indicate whether the means 60 is to be inserted. LED lamp 131 comprises a pair of LED lamps 131, 131 that emit light of different colors from each other, for example if one of the LED lamp 131 is lit means to insert one of the wire _{W 1,} the other LED lamp If 131 is lit refers to the insertion of the other wire W _2. For this reason, a pair of LED lamps 131 and 131 function as an electric wire selection display part which displays the electric wire which should be inserted.

Furthermore the display unit 130A of the control monitor 130 instead of the pair of LED lamps 131, the type of wire to be inserted into the strip means 60 of the strip mechanism 60A, for example, that of inserting one of the wire _{W 1,} view and Also good.

Next, the electric wire holding mechanism 110 will be described. As shown in FIG. 1, the electric wire holding mechanism 110 holds a pair of electric wires W ₁ and W ₂ sent separately from the strip mechanism 60 together. Such wire holding mechanism 110, for example, while gripping the first wire W ₁ coming originally sent, a first holding claw 110a of the vertically movable, under the first holding claws 110a position and has a second holding claw 110b for gripping second-second wire W ₂ sent. Among these, the first holding claw 110a can be moved up and down by the lifting mechanism 110A.

By the way, on the gantry 20, a discharge mechanism 120 for discharging a pair of electric wires W ₁ and W ₂ having the terminal 1 crimped to the front end by the terminal crimping applicator 15 is provided. The discharge mechanism 120 is configured to hold a pair of electric wires W ₁ and W ₂ having a terminal 1 crimped to the front end and convey the wire W ₁ and W ₂ to the front side in the front-rear direction and then to the lateral direction (left side).

Incidentally, the wire W _1, W terminal 1 is crimped to the front end of ₂ has a projection 2 towards the outside, the projections wire when this since the electric wires W _1, W ₂ and conveyed to the front-rear direction of the front side if interferes with part of the obstacle 100A of the terminal crimping system 100, the discharge mechanism 120 of the terminal 1 is once moved to the right while gripping the pair of electric wires W _1, W ₂ of the terminal 1 is crimped to the front end Interference between the protrusion 2 and the obstacle 100A can be avoided (see FIG. 11). In this case, the discharge mechanism 120 then transports the pair of electric wires W ₁ and W ₂ to the front side in the front-rear direction, and then transports them in the lateral direction (left side). Here, FIG. 11 is a side view showing the electric wires W ₁ and W ₂ whose terminals are crimped to the front end. As the obstacle 100A, a part of the terminal crimping applicator 15, such as a slide cutter, can be considered.

  Next, the operation of the present embodiment having such a configuration, that is, a method for crimping a wire terminal will be described.

Of LED lamp 131 is first provided in the vicinity of the control monitor 130, a display indicating that one of the LED lamp 131 is lit, inserting a first wire _{W 1} to the strip means 60 of the strip mechanism 60A to the operator (Wire selection display step).

In this case, instead of the LED lamp 131 as described above, it may be displayed indicating that inserting a first wire _{W 1} to the strip means 60 of the strip mechanism 60A on the display unit 130A of the control monitor 130.

Then the operator checks the display of the display portion 130A of the display or control monitor 130 of LED 131, the first wire W ₁ that is holding in his hand by feeding forward, the insertion of the sensor body 75 to the front end Insert into hole 75a. In this case the sensor body 75 transmits a signal indicating that the first wire W ₁ is fed forward by the operator's hand control monitor 130.

Next, the control monitor 130 operates the first holding unit 40 and holds and fixes the front end of the first electric wire W ₁ by the chuck 41.

  Next, the control monitor 130 operates the second slide unit 50 to retract the sensor main body 75 and the strip means 60 together by a small distance to the back side in the front-rear direction, and then moves the air cylinder 72 of the sensor means 70. The sensor body 75 is retracted upward by operating.

Thus, compared to when retracting the sensor body 75 upwardly directly, first wire W ₁ is not able to interfere with the sensor body 75, nor thereby become bent its front end portion.

  Next, the control monitor 130 operates the second slide unit 50 to advance the pair of upper and lower strip blades 67a and 67b of the strip means 60 to a predetermined position on the front side in the front-rear direction.

While moving this time also integrally sensor body 75, sensor body 75 does not interfere with the first and are retracted upward to the front end portion of the wire W _1.

Furthermore, the control monitor 130 activates the strip means 60, a pair of upper and lower strip blades 67a, is brought closer to each other 67b in the vertical direction, cutting the first front end portion of the wire W ₁ at a predetermined position in the longitudinal direction.

Accordingly, the first wire W ₁ is cut from the front surface of the chuck 41 as shown in FIG. 6 at a position at a predetermined distance L.

Even if such a worker feeding forward gripped by the first hand the wire W _1, is possible to solve the misalignment problem in the front-rear direction of the relative positions of the first wire W ₁ and the chuck 41 it can. Therefore, the first front end of the wire W ₁ can be accurately strip, to enhance the quality of the work of crimping terminals to the front end of the electric wire working and strip first strip front end of the wire W ₁ it can.

Note that debris generated by the cutting of the first front end portion of the wire W ₁ is removed by suction through a pipe 68.

The cutting of the first front end portion of the wire W ₁ is completed, the control monitor 130, after the strip means 60 is operated by separating the upper and lower pair of strip blades 67a, a 67b in the vertical direction, the second slide unit 50 Is operated to move the pair of upper and lower strip blades 67a and 67b to a predetermined position on the front side in the front-rear direction.

Then, the control means, after the strip means 60 is operated so cut a pair of upper and lower strip blades 67a, a 67b to the first insulating coating of the wire W _1, the back side of the second slide unit 50 front-rear direction To complete the strip operation (strip process).

The first debris insulating coating caused by the front end portion of the strip of the wire W ₁ is removed by suction through a pipe 68.

When the first front end of the strip of the wire W ₁ is completed, the control monitor 130 moves the chuck 41 of the first holding portion 40 by operating the first slide unit 30 to the left.

However, the strip means 60, a pair of strip blades 67a, the 67b near the wire detection sensor 70A for detecting the first profile of the wire W ₁ front end is stripped is attached (see FIG. 7). The electric wire detection sensor 70A includes a projector 70a that emits fiber light or laser light, and a light receiver 70b that receives the fiber light or laser light from the projector 70a. Then, immediately after the first slide unit 30 moves the chuck 41 of the first holding unit 40 to the left side, the electric wires W ₁ and W ₂ pass between the light projector 70a and the light receiver 70b. The outer diameter of this time fiber optic or coating of laser wire W ₁ by the photo detector 70b for receiving _light, W _2, to detect the stripped wire W _1, W ₂ of the outer diameter of the front end (core diameter) it can.

In other words, the pair of strip blades 67a and 67b of the strip means 60 has a diameter of the electric wires W ₁ and W ₂ when the first electric wire W ₁ has a large diameter and the second electric wire W ₂ has a small diameter, for example. The amount of cutting is changed according to.

Therefore, even if the first wire W ₁ to be processed is the first wire W ₁ having a large diameter, when the second wire W ₂ having a small diameter is mistakenly inserted into the strip means 60, a pair of strip blades 67a, 67b will be first with a depth of cut corresponding to the wire _{W 1} by cutting the second wire _{W 2} or strips, of large diameter. In this case, or securely cut the second front end of the wire W ₂ of the small-diameter, it can not be stripped, eventually the second front end of the wire W ₂ can not exhibit the desired appearance.

On the other hand, if it is inserted into the first correctly strip means 60 the wire W ₁ of the large diameter, a first front end of the wire W ₁ can exhibit the desired appearance.

Wire detection sensor 70A detects a first outer diameter or the second front end outer diameter of the wire W ₂ of the front end of the wire W ₁ after strips and sends the detection signal to the control monitor 130. The electric wire detection sensor 70A includes the projector 70a and the light receiver 70b. However, the electric wire detection sensor 70A may include a CCD camera.

Based on the detection signal from the electric wire detection sensor 70A, the control monitor 130 compares the front end outer diameter information of the normally stripped electric wires W ₁ and W ₂ incorporated in advance, and determines the erroneous electric wires W ₁ and W ₂ . In the case of stripping, an error display (error display process) indicating that the inserted electric wires W ₁ and W ₂ are wrong is performed and an alarm is issued. At this time, the control monitor 130 functions as an error display unit and also functions as an alarm unit, and stops the wire terminal crimping system 100 as a whole.

Next, the control monitor 130 continues to move the first slide unit 30 to move the chuck 41 of the first holding unit 40 to the left side, and the front end of the first electric wire W ₁ is moved forward of the electric wire holding mechanism 110. Bring it (first transport step).

Then lowered by the elevating mechanism 110A in a state where the first holding claws 110a are in the open wire holding mechanism 110, grips the first wire W ₁ held by the first holding portion 40. Then the chuck 41 of the first holding portion 40 is opened, the first wire _{W 1} is Jigae from the first holding portion 40 in the first holding pawl 110a.

Then the first holding pawl 110a is moved upward while holding the first wire W _1, it waits at this position.

In this way, the first wire W ₁ is held by the first holding claws 110a of the wire holding mechanism 110, the first wire W ₁ waits.

Then in the same manner as described above, the second electric wire (thin electric wire) the front end of the W ₂ is stripped by the strip mechanism 60A, a second wire W ₂ where the front end is strip of the first holding portion 40 chucks 41 forwards the wire holding mechanism 110. At this time, the second front end of the wire W ₂ faces the wire holding mechanism 110 side.

Then grips the second wire W ₂ of the second holding claws 110b of the wire holding mechanism 110 is held in the first holding portion 40 is closed. Then it chuck 41 of the first holding portion 40 is opened, the second wire _{W 2} are Jigae from the first holding portion 40 to the second holding claw 110b.

Then, holding the first holding claws 110a of the wire holding mechanism 110 is lowered, in the wire holding mechanism 110, the first wire _{W 1} and the second holding claw 110b which is held in the first holding pawl 110a by second wire W ₂ and are arranged continuously in the vertical direction. Next, the first electric wire W ₁ and the second electric wire W ₂ arranged in the vertical direction are held by the pair of chucks 40 a and 40 b provided in the second holding portion 40 A operated by the first slide 30.

At this time, the first wire _{W 1} and a second wire _{W 2} arranged in the vertical direction and the claw 40c of the chuck 40a, the pawl 40d of the chuck 40b, is sandwiched from the left and right directions, slightly inclined relative to the vertical direction Are held side by side in the direction (electric wire holding step). Next, the first holding claw 110a and the second holding claw 110b are opened, and the second holding portion 40A is moved to the left by the first slide 30 (see FIG. 5).

In this way, the first wire W ₁ and a second wire W ₂ is fed to the front of the terminal crimping applicator 15 together by the second holding portion 40A (second transfer step).

  By the way, as shown in FIG. 5, the second holding portion 40 </ b> A is connected to the first holding portion 40 driven by the first slide 30. For this reason, the first holding unit 40 and the second holding unit 40 </ b> A move together in the left-right direction by the first slider 30.

Thus while the first holding portion 40 of the first wire _{W 1} or the second wire _{W 2} are conveyed from the strip mechanism 60A to the wire holding mechanism 110, the first wire _{W 1} and a second wire _{W 2} at the same time It can be conveyed by the second holding part 40A as a unit from the electric wire holding mechanism 110 to the front of the terminal crimping applicator 15.

Incidentally, the strip by a first time of the wire W ₁ and a second wire W ₂ is moved to the left, that is, the first holding portion 40 is strip mechanism 60A in which the second holding portion 40A is held in the wire holding mechanism 110 When the first electric wire W ₁ or the second electric wire W ₂ is moved to the left side, the control monitor 130 controls the operation of the first electric motor 34 to start the movement of the first slide unit 30. Keep the speed low.

Thus, even if the chuck 41 of the first holding unit 40 starts to move to the left side from the strip mechanism 60A in a state where the operator holds the electric wires W ₁ and W _{2 in} their hands, the front ends of the electric wires W ₁ and W ₂ Since the speed at which the portion starts to move to the left side is low, an operator holding the wires W ₁ and W ₂ by hand can easily follow the movement to the left side.

Moreover, the electric wires W ₁ and W ₂ can be quickly moved to the electric wire holding mechanism 110 or the terminal crimping applicator 15 by gradually increasing the speed of the first slide unit 30 after a predetermined time has elapsed.

Further, immediately before the electric wires W ₁ and W ₂ reach the electric wire holding mechanism 110 or the terminal crimping applicator 15, the operator stops the movement to the left side by reducing the moving speed of the first slide unit 30. Can be easily accommodated.

A pair of chucks 40a of the second holding portion 40A, a first wire W ₁ and a second wire W ₂ are terminal crimping applicator 15 40b are aligned in a direction slightly inclined relative to the vertical direction by moving to the left , The control monitor 130 operates the terminal crimping press 10 to connect the terminal 1 to the core wire exposed at the front ends of the electric wires W ₁ and W ₂ arranged in a slightly inclined direction with respect to the vertical direction. Crimp the. At this time, the electric wires W ₁ and W ₂ are arranged in the horizontal direction, and terminals are crimped to the front ends of the electric wires W ₁ and W ₂ (terminal crimping step) (FIG. 11).

And the physical burden can be reduced.

Further, during the strip operation, the chuck 41 of the first holding unit 40 holds and fixes the front end portion of the electric wire W, so that the electric wires W ₁ and W ₂ held by the hand are moved in the front-rear direction. The quality of the strip operation can be improved without being displaced.

In addition, according to the present embodiment, a pair of different types of electric wires W ₁ and W ₂ are definitely selected, inserted into the strip mechanism 60A, and the front ends of the electric wires W ₁ and W ₂ correctly selected are selected by the strip mechanism 60A. Can be stripped accurately. Further, after the electric wires W ₁ and W ₂ whose front ends are stripped in this way are securely collected in the electric wire holding mechanism 110, the terminals can be accurately crimped to the front ends of the electric wires W ₁ and W ₂ by the terminal crimping applicator 15. it can.

In addition, the electric wire terminal crimping system 100 of the present embodiment is provided with the first slide unit 30, the first holding portion 40, and the second holding portion 40A in the front portion 22 of the gantry 20 in the left-right direction. Due to the reciprocating structure, the function of holding and transporting the front end portions of the electric wires W ₁ and W ₂ of a commercially available terminal crimping press 10 already installed is compactly achieved along the gantry 20. be able to.

Further, since the strip mechanism 60A is provided on the right side of the gantry 20 and the strip mechanism 60A is reciprocated in the front-rear direction, the front end portions of the electric wires W ₁ and W ₂ that are gripped by the operator's hand and extend in the front-rear direction. The function of stripping in the front-rear direction can be achieved compactly along the right side of the gantry 20.

  Therefore, the first slide unit 30, the first holding unit 40, the second holding unit 40A, and the strip mechanism 60A can be easily retrofitted to a commercially available terminal press 10 that is already installed. In addition, the structure is simple and the manufacturing cost can be reduced.

  As mentioned above, although one Embodiment of this invention was described in detail, it cannot be overemphasized that this invention is not limited by embodiment mentioned above and a various change is possible.

  For example, in the above-described embodiment, a strip mechanism is provided on the right side of the gantry 20, but a strip mechanism is provided on the left side of the gantry 20 in accordance with the structure of a commercially available terminal crimping press. Needless to say, you can.
