DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a linear member transfer device for transferring a linear member such as a cut wire in a direction orthogonal to its longitudinal direction.

(Prior Art and Its Problems) FIG. 17 is a perspective view of a main part of a conventional wire transfer device incorporated in a terminal driving machine. As shown in the figure, the upstream clamp that can hold and release the electric wire 10 along the electric wire feeding line X
2, a set of two cutters 3 and a downstream clamp 4 such as a first clamp capable of grasping and releasing the electric wire 10 are arranged.

FIG. 19 is a plan view of an essential part of the electric wire transfer device, and FIG.
It is the II sectional view taken on the line of FIG. As shown in the figure, a cover member 9 is disposed below the downstream clamp 4 along a horizontal plane, and an electric wire discharge portion 9a is provided at a left end portion of the cover member 9. Further, the second clamp such as the discharge clamp 7 arranged above the left end of the cover member 9 is configured to be capable of grasping and releasing the cutting electric wire 10a described later, and is located above the left end of the cover member 9. And a position above the electric wire discharging portion 9a.

The upstream side and downstream side clamps 2 and 4 are each configured to be movable in a three-dimensional direction, and in this device, operations as described below are performed.

As shown in FIG. 17, first, in a state where the holding of the electric wire 10 by the upstream and downstream clamps 2 and 4 is released, the electric wire 10 is fed along the feeding line X by an electric wire feeding means (not shown). It is fed in the P direction, and then the electric wire 1 with both clamps 2 and 4.
0 is gripped, and the electric wire 10 is cut by the cutter 3. Next, the upstream clamp 2 is advanced by a predetermined amount in the arrow P direction, and the covering portion of the residual electric wire 10 held by the upstream clamp 2 is cut by the cutter 3. In that state, the upstream clamp 2 is moved in the arrow Q direction. By retracting, the covering portion at the end of the residual electric wire 10 is peeled off. Then, the upstream clamp 2 is moved horizontally along the horizontal direction to the right as shown by the arrow R in the figure, and the terminal 6 is attached to the stripped end of the residual electric wire 10 by a terminal crimping machine (not shown).
Is crimped, and then the upstream clamp 2 is returned to the original position shown in FIG.

On the other hand, while the terminal 6 is crimped to the residual electric wire 10, the downstream clamp 4 is retracted by a predetermined amount in the direction of the arrow Q and is covered by the cut electric wire 10a (shown in phantom line in the figure). Is cut by the cutter 3, and the downstream clamp 4 moves in the direction of the arrow P in that state to cut the electric wire 10a.
The coating portion on the upstream side of the electric wire feeding direction P is peeled off. Then, as shown in FIGS. 21 and 22, the downstream clamp 4 is moved in the horizontal direction by a predetermined amount in the left direction shown by the arrow S in FIG. As shown in Fig. 24, cut the wire 10
The terminal 8 (see FIG. 18) is crimped to the upstream end of a.
After that, the downstream clamp 4 is lifted upward by a predetermined amount, and at the raised position, the discharge clamp 7 grips the cutting wire 10a, and the downstream clamp 4 cuts the cutting wire 10a.
The grip of a is released, and the cut wire 10a is clamped on the downstream side clamp 4
Is delivered to the discharge clamp 7. Then, as shown in FIG. 25 and FIG. 26, the downstream side clamp 4 moves downward while moving downward and returns to the original position shown in FIG. The discharge clamp 7 moves to the left as shown by arrow S in FIG.
Release the grip of a, and then cut wire with terminals crimped on both ends 1
0a (harness) is discharged to the wire discharge portion 9a. Such operations are continuously repeated to sequentially manufacture the harness.

However, in this type of conventional electric wire transfer device, the downstream clamp 4 needs to grip the upstream end of the cut electric wire 10a because of the above-described electric wire cutting processing, coating stripping processing, and the like. It is necessary to move the cut electric wire 10a in a direction orthogonal to its longitudinal direction. Therefore, at the start of the movement of the cutting wire 10a, as shown in the imaginary line in FIG. 21, a region downstream of the position where the cutting wire 10a is gripped by the downstream clamp 4 (hereinafter, simply referred to as "downstream region") is generated. Due to the inertia, it shakes largely to the right, and then, when the downstream clamp 4 stops, the downstream region of the cutting wire 10a vibrates in the opposite direction as shown by the imaginary lines in FIGS. 18 and 23. Is bent to the left. This allows the
As shown by the imaginary line in Fig. 25, there was a problem that the cut electric wire 10a was discharged to the electric wire discharging portion 9a while being bent.

In addition, in order to suppress the lateral vibration of the cutting electric wire 10a,
An electric wire transfer device A as shown in FIGS. 28 and 28 and an electric wire transfer device B as shown in FIGS. 29 to 31 are conceivable. In the wire transfer device A, a right runout prevention wall 12 is provided on the right side of the feed line on the cover member 9 along the feed line, and a left runout is prevented along the left end of the wire discharge part 9a. A wall 13 is projected. Then, the horizontal shake of the cutting electric wire 10a when the downstream clamp 4 moves to the left is prevented by the left and right shake preventing walls 12 and 13. On the other hand, the electric wire transfer device B shown in FIGS. 29 to 31 has a position below the electric wire feeding line on the downstream side of the downstream clamp 4.
And a receiving plate extending in the downstream direction along the horizontal plane
11 is attached so as to move integrally with the downstream side clamp 4, and further, a right runout preventing wall 12 is provided on the right end portion of the receiving plate 11 along the end portion of the receiving plate 11 and the wire discharge portion. A left shake preventing wall 13 is provided so as to protrude along the left end portion of 9a. Then, while the downstream side clamp 4 is moving to the left, the downstream side area of the cutting electric wire 10 is moved to the left and right anti-sway walls 12, 13
It is configured to prevent lateral vibration of the cutting electric wire 10a by locking with.

However, in such electric wire transfer devices A and B, the cutting electric wire 10a during the movement of the downstream side clamp 4 in the left direction is performed.
Although the right runout prevention wall 12 can be prevented by the right runout prevention wall 12 respectively, the left runout prevention wall 13 of both the devices A and B prevents the cut wire 10a from running to the left when the downstream clamp 4 is stopped. Since it must be provided on the left side of the electric wire discharging portion 9a (details thereof will be described later), as shown in FIG.
There is a problem in that the downstream side region is largely swung to the left beyond the electric wire discharging portion 9a, and the bending of the cut electric wire 10a cannot be reliably prevented.

In the electric wire transfer device B shown in FIGS. 29 to 31, the left runout preventing wall 13 is provided so as to project along the right side of the electric wire discharging portion 9a instead of the left side, and is laterally arranged within the width of the receiving plate 11. Although it may be possible to prevent the runout, the work of delivering the cutting wire 10a to the discharging clamp 7 and then moving the discharging clamp 7 to the left to discharge the cutting wire 10a to the wire discharging portion 9a is smoothly performed. Disappear. That is,
The downstream region of the cut wire 10a gripped by the discharge clamp 7 hangs downward due to its own weight, and when the discharge clamp 7 moves to the left, the downstream region of the cut wire 10a moves to the surface of the receiving plate 11 and The surface of the cover member 9 is guided to the electric wire discharging portion 9a. Therefore, if the left runout prevention wall 13 is provided on the right side of the wire discharge part 9a, the downstream side region of the cut wire 10a is locked to the left runout prevention wall 13 and the wire discharge part of the cut wire 10a is locked. Moving to 9a will not be smooth.

Next, the operation of this harness manufacturing unit will be described. Before the operation is started, the upstream and downstream clamps 200 and 300 are in a state where the electric wires 600a and 600b are not gripped, and the discharging clamp 553 of the discharging means 550 is in the right direction shown by the arrow R in FIG. At the moved position, the two pairs of clamp claws 554a and 554b of the discharge clamp 553 are in the open state. Furthermore, the downstream clamp
The stopper 702 in 300 is in a state of protruding upward while being along the left end of the linear member receiving plate 700. From this state, as shown in the flow chart of FIG. 6, the electric wire 600 is moved by the pair of conveying parts 51, 51 of the electric wire feeding means 50.
Arrows P along the feeding line X while a and 600b are being sandwiched
Is fed by a predetermined amount (steps S1 and S2), and the upstream side clamp 200 grips the upstream side with respect to the wire feeding direction P in the vicinity of the planned cutting area of the wires 600a and 600b, and the downstream side clamps the downstream side clamp 300. Are gripped respectively. Next, as shown in step S3, the pair of cutters 100, 100 performs a cutting process by sandwiching the wires 600a, 600b from above and below, and the residual wires 600a, 600b gripped by the upstream clamp 200 and the downstream clamp. 300
It is gripped by and is divided into cutting electric wires 601a and 601b. Then, as shown in step S4, the upstream clamp 200
Moves forward in the direction of arrow P by a predetermined amount, and the covering portions on the downstream side of the two residual electric wires 600a, 600b gripped by the cutters 100, 100
Is cut by the upstream clamp.
200 moves backward in the direction of arrow Q, and the downstream coating portions of the two residual electric wires 600a and 600b are stripped off (first coating stripping process). After that, in step S5, the upstream clamp 200 moves in the direction of arrow R orthogonal to the feeding line X, and the first terminal crimping means 400 moves the two residual electric wires 600a, 600b to the downstream stripped end portions. After the terminals 602, 602 are crimped respectively (first
Terminal crimping process), the upstream side clamp 200 moves in the arrow S direction and returns to the original position shown in FIGS. 1 and 3. On the other hand, as shown in step S7, while the first terminal crimping process (step S5) is being performed, the downstream clamp 300 is retracted in the arrow Q direction by a predetermined amount, and the two clamps gripped by it are cut. The coating on the upstream side of the electric wires 601a and 601b is the cutter 1.
Each of them is cut by 00 and 100, and the downstream clamp 300 advances in the direction of arrow P while keeping the cut state, and the upstream coating portions of the two cut wires 601a and 601b are stripped (second coating stripping). Processing). Next, in step S8, the downstream clamp 30
0 indicates a leftward direction (one-sided direction) indicated by an arrow S in order to execute the second terminal crimping process as shown in FIGS. 9 and 10 from the state shown in FIGS. 7 and 8. Moved to.
At the start of this movement, a region downstream of the position where the cutting wires 601a and 601b are gripped by the downstream clamp 300 (hereinafter, simply referred to as a "downstream region") receives a force that swings in the right direction indicated by an arrow R due to inertia. However, at the slightly swung position, the downstream region is locked to the vertical piece 700a of the linear member receiving plate 700 to suppress the lateral shake. Thus, FIG. 11 and FIG.
As shown in FIG. 12, the downstream clamp 300 is moved leftward as indicated by the arrow S by a predetermined amount and stopped. At this time, the downstream side regions of the cut electric wires 601a and 601b receive a force of swinging to the left as shown by the arrow S opposite to the above due to inertia, but the stopper 70
Since 2 is projecting above the linear member receiving plate 700, it is locked to the stopper 702 at a position where the downstream side regions of the cut electric wires 601a and 601b are slightly swung, and is moved to the left as indicated by the arrow S. Lateral runout is suppressed, thus cutting electric wires 601a, 601b
Bending is prevented.

Next, by the second terminal crimping means 500, two cut wires 601a,
Terminals 603 and 603 (see FIG. 4) are crimped to the upstream stripped end of 601b. Then, in step S9, as shown in FIG. 4, the downstream clamp 300 is raised by a predetermined amount, and the cutting wire 6
Regions on the upstream side of the grip position of the downstream clamp 300 of 01a and 601b are inserted between the pair of clamp claws 554a and 554b of the discharge clamp 553, respectively. Next, thirteenth
As shown in Fig. 14 and Fig. 14, a pair of clamp claws 554a, 5
54b is closed and the discharge clamp 553 cuts the electric wire.
As the 601a and 601b are gripped, the movable claws 307 and 307 of the downstream clamp 300 are respectively retracted, and the grip of the cut wires 601a and 601b by the downstream clamp 300 is released. Further, the stopper 702 is retracted below the horizontal piece of the linear member receiving plate 700 by driving the cylinder 705.

Then, as shown in Figs. 15 and 16, the discharge clamp.
553 is moved along the rail 552 in the left direction (one side direction) indicated by the arrow S. In this case, since the stopper 702 is at a position retracted downward from the horizontal piece of the linear member receiving plate 700, the downstream area of the cut electric wires 601a and 601b is located at the stopper 7.
It is smoothly guided to the wire discharge part 560 without being locked by 02. In this way, when the discharge clamp 553 is moved to the position of the electric wire discharge portion 560, the pair of clamp claws 554a, 554b are opened, and the cut electric wire 601a,
The grip on 601b is released, and terminals 602 and 603 are
The crimped cut electric wires 601a and 601b (harness) are discharged to the electric wire discharge portion 560 (discharge processing).

On the other hand, the downstream clamp 300, which has delivered the cut wires 601a, 601b to the discharge clamp 553, is moved in the arrow R direction while descending by a predetermined amount downward as indicated by the arrow U in FIG. After moving to the position, it is lifted up by a predetermined amount as indicated by arrow T. In parallel with the movement of the downstream clamp 300 to the original position, steps S6 and S10 are performed.
Then, the electric wires 600a and 600b are indicated by arrow P along the electric wire feeding line X.
A predetermined amount is fed in the direction, and the electric wires 600a and 600b are gripped by the upstream clamp 200 and the downstream clamp 300.
In this way, the process returns to step S3 again, and the above-described operation is repeated to sequentially manufacture two harnesses in which the terminals 602 and 603 are crimped at both ends.

(Effect of the Invention) As described above, according to the linear member transfer device of the present invention,
Since a stopper is provided at one end of the linear member receiving plate fixed to the first clamp such as the downstream clamp so that the linear member receiving plate can be retracted and retracted, it is in a protruding state when the movement of the first clamp in one direction is completed. A certain stopper can prevent lateral deflection of the linear member to prevent the linear member from bending, and when the second clamp such as the discharge clamp holding the linear member is further moved in one direction, the stopper is retracted. The effect that the linear member can be smoothly transferred in one direction is obtained.
