Conventionally, the steps described above can be automated and can be carried out.

However, all the above steps have been performed manually.

[0005]

The reason is that the end of the electric wire cable wound around the discharged bobbin is in various positions in various positions. Therefore, it was difficult to find out where the bobbin is located without the eyes of a person. In addition, since the terminal is in various positions on the bobbin in various states, it was almost impossible to judge the place to put the label without human eyes.

[0006]

SUMMARY OF THE INVENTION The present invention is directed to a bobbin holder that holds a take-up bobbin sent from a winder in a fully wound state so that it can be driven to rotate or rotate freely, and a drive for the bobbin holder.

[0007]

[Operation] The bobbin holding table receives the winding bobbin sent from the winding machine in a fully wound state.

When the bobbin holding base is driven and rotated to rotate the winding bobbin in the winding direction, the electric wire cable end which has exceeded the top of the bobbin in one rotation falls.

When the falling terminal is guided by a chute-shaped guide and guided to a narrow area below, the detector in the narrow area detects that the terminal has passed, so that the bobbin is held. Stop the platform.

The terminal hangs in the narrow area below the chute-shaped guide. Therefore, the terminal can be easily held by the first chucking.

The first chucking is moved and the terminal is pulled out while being pulled. The second chucking holds the terminal thus dispensed.

When the loss take-up drum is driven to rotate, the end loss of a predetermined length can be taken up. Therefore, the terminal loss can be removed by cutting a predetermined length with a cutter.

That is, in this embodiment, the bobbin 10 sent by the carry-in means 1 shown in FIG. 1 has two kinds of winding directions instead of one kind, and the bobbin 10 has the turns shown in FIGS. 3 and 4. A case where the table frame 20 and the motor 30 are configured so that the direction can be changed so that the direction of the arrow E is self-winding (for the next step) is shown.

Reference numeral 31 is a chute-shaped guide attached to the turntable frame 20. In the illustrated example, the turntable frame
It is attached to the front and rear of 20, respectively, each guide 31,
The take-up bobbin 10 is constituted by two upwardly expanding guide plates 31a, 31a, and the winding bobbin 10 is in the direction of arrow E.
When it is rotated to ─, the end of the electric cable is free fall and is guided to the lower narrow area 32.

That is, in FIG. 9, when the bobbin 10 rotates, the terminal 33a of the electric wire cable 33 wound as shown by the imaginary line falls down as shown by the arrow F, but the entire width of the bobbin 10 is reduced. Even if the terminal 33a exists at any position, the terminal 33a is received by the guide plates 31a and 31a which are widened more than the entire width, and the guiding guide is performed until the terminal 33a hangs down to the position shown by the solid line in FIG.
(This state is also sequentially shown in FIGS. 10, 11, 12, and 13.)

In the narrow range 32, however, the detector 34
Is provided to detect that the terminal 33a has passed (falled). For example, the detector 34 is configured by a laser light illuminator and a photoelectric tube that receives the light, and as shown in FIG.
If 33a crosses as indicated by arrow G, it is detected.

Further, in FIGS. 3 to 5 and FIG. 13, when the detector 33 detects the terminal 33a, the terminal 33a is moved forward to the narrow range 32, and the terminal 33a is held and held. Terminal 33
First chucking 35 that pulls a while retracting to a predetermined position

The first chucking 35 is composed of a pair of chucking plates 36, 36 provided so as to be able to approach and separate from each other by a screw shaft and a slide rod, a motor 37 for performing the approaching and separating operation, and a belt / pulley. A driving force transmission mechanism 38 such as, a movable table 39 on which these are mounted, a horizontal guide member 40 for guiding the movable table 39 forward and backward, and a drive mechanism 41 for performing the forward and backward movements, Composed.

The drive mechanism 41 is a motor 42, a rotating body 43 such as a pulley or a chain wheel, and is endlessly suspended by the rotating body 43, and a part of the driving mechanism 41 is arranged along the horizontal guide member 40. It consists of linear bodies such as belts and chains.

The movable table 39 is fixed to a part of the linear member 44 and is moved forward and backward as indicated by arrows H and I. In FIG. 4, the position of the movable table 39 shown by the phantom line is the most advanced position, and a part of the chucking plate 36 is a chute-shaped guide 31.
This is a position where the terminal 33a hanging through the narrow range 32 (as described above) can be held, as shown in FIG.

The position of the movable table 39 shown by the solid line in FIG. 4 and FIG. 15 is the final retracted position, and the electromagnetic clutch of FIG.
When the movable table 39 is retracted in the direction of arrow I from the bobbin 10 on the idle roller 23 with 27 turned off, the terminal 33a is held in place, the bobbin 10 moves in the opposite direction of arrow E. The terminal 33a is pulled out and comes out to the position J in FIGS. 15 and 4.

A second chucking 45 is (possibly) located in the middle of the J position and is attached to a part of the loss winding drum 46.

The loss take-up drum 46 is a drum for taking up the terminal 33a over a predetermined length, which is likely to be scratched in the insulating extrusion step and the winding step in the preceding steps, as an end loss.

The loss take-up drum 46 is rotatably supported on a base 47 so as to be rotatable about a horizontal axis, and is rotationally driven by a motor 48. An electromagnetic clutch is provided midway in the power transmission system.
49 are intervened. Further, the drum 46 has a cutout portion 51 at a part of the circumferential edge of the one flange portion 50. This notch 51
And the second chucking 45 including a reciprocating operation mechanism (details not shown) such as a solenoid or a fluid cylinder, and the like. It is attached to the position of the notch 51 of the collar 50.

Strictly speaking, the inner end edge itself of the cutout portion 51 of the collar portion 50 also constitutes a part of the second chucking 45.

Further, in the illustrated example, the other brim portion 54 is composed of a plurality of radial holding plates 55 that can be folded and unfolded, and is folded when the wound end loss is close to full winding. Therefore, the terminal loss can be easily removed.

In FIGS. 4 and 15, the loss winding drum 46 is slightly rotated to stop the second chucking 45 so that it is in the J position in advance, and as shown in FIG. , This second
Hold the chucking 45 open, then
When the clasping pieces 52, 52 of the first chucking 35 are retracted in the direction, the terminal 33a that is naturally pulled out (as shown at the J position) passes through the second chucking 45.

That is, the pulled-out terminal 33a passes between the cutout portion 51 and the clasp piece 52 in the open state (see FIG. 15).

Therefore, if the second chucking 45 is closed in the direction of arrow K, the terminal 33a is sandwiched by the inner edge of the notch 51 and the outer edge of the sandwiching piece 52, as shown in FIGS. It is worn (grabbed).

Next, as shown in FIG. 17, the loss winding drum 46 is rotationally driven in the direction of arrow L. At this time, the clutch 27 in FIG.
Is released, and the winding bobbin 10 on the bobbin holding table 17 is left in an idle state.

In this way, the terminal loss of a predetermined length is wound on the loss winding drum 46 as shown in FIG.

Reference numeral 56 denotes a cutter, which is located near the loss winding drum 46 and has a large vertical stroke so that the terminal can be cut in any range from the J position to the M position in FIG. As shown in FIG. 3, the actuator 57 retracts laterally outward when not in use.

Further, a guide roll 58 is provided near the cutter 56 and traverses in the direction of arrow N.

Further, the turntable frame 20 is provided with a pressing roller 59 in a horizontal shape and in the lateral direction. This presser roller 59 is provided with an actuator 60 such as a fluid pressure cylinder.
The electric wire cable wound on the take-up bobbin 10 as shown in FIG.
The outer peripheral surface 33b of 33 is pressed over a predetermined width, and the terminal 33a
The label is prevented from coming loose and the label crimping action described later is performed.

By the way, as shown in FIGS. 17 to 18, the loss winding drum 46 is rotated in the direction of the arrow L by a preset bobbin rotation speed, and the guide roll 58 is traversed, while the terminal of a predetermined length is rotated. Wind up Ross.

Next, the winding is stopped, and the clutch 49 on the winding side is stopped.
Is released and the delivery side clutch 27 is closed, and the guide roll 58 is at the origin --- in FIG.
And on the widthwise center plane Q of the take-up bobbin.

Then, in FIG. 18, the winding bobbin 10 is rewound by about 2 to 3 turns (rotates counterclockwise). Since the guide roll 58 is at the origin, the terminal 33a of the electric wire cable 33 comes within the widthwise range R of the diagonal line in FIG.

Therefore, the actuator 60 is extended to raise the pressing roller 59, fix the outer peripheral surface 33b of the electric wire cable 33 wound as shown in FIG. 18, and cut the end 33a with the cutter 56. .

A length P ₁ slightly shorter than the length P ₀ from the cutting point 61 to the pressing point 62 pressed by the pressing roller 59.
Is taken as the extra length and is further rewound on the winding bobbin 10. That is, the feeding extra length P ₁ to the vicinity of the pressing point 62 of the pressing roller 59 is rewound (see FIG. 20).

At this time, the outer peripheral surface 33b by the pressing roller 59
By continuing to press on the terminal 33a
Are held as shown by the solid line in FIG. 20 and are located in the shaded area R in FIG.

Then, by the automatic label sticking device 3,
The label 64 is attached to the outer peripheral surface 33b. In the specific example shown in FIG. 20, since the label 64 is attached from the horizontal direction S, the length from the label attaching position to the final end of the terminal 33b is small--
─ About 90 degrees at the center of rotation of bobbin 10 ───.

If the width of the label 64 is set slightly larger than the range R as shown in FIG.
a can be fixed. Further, the label sticking device 3 has a function of automatically printing various kinds of data such as the type / dimension / material of the electric wire cable 33 and the manufacturing factory name and the manufacturing date on the label 64.

Further, as shown by the phantom line and the solid line in FIG. 20, the height position of the pressing arm 65 for pushing out the label 64 is continuously variable and can correspond to the size of the bobbin 10.

After that, the pressing arm 65 of the automatic label sticking device 3 is retracted, the pressing by the pressing roller 59 is continued as shown in FIG. 21, and the winding bobbin 10 is rotated in the arrow T direction. The crimped label 64 is the outer peripheral surface
It is securely crimped along 33b.

As is clear from the above, the pressing roller 59 is
The action of holding the terminal 33a so that it does not come loose, and the label 64
The function of performing full pressure bonding is performed.

By the way, as shown in FIG. 8, each of the above-mentioned devices is controlled by a main control circuit 66 for controlling a winding machine for winding after the insulating extrusion process and a sub-control circuit 67 interlocking with the main control circuit 66. .

That is, the main control circuit 66 to the sub control circuit 67
To the bobbin winding direction and the bobbin position signal U ₁ , and in the reverse direction, the terminal processing device 2, the label sticking device 3, the loading means 1 and the unloading means 4, and the signal U 1 indicating the bobbin position and the like. ₂ will be sent.

In particular, the label attaching device 3 from the sub control circuit 67
In addition to instructing the label sticking timing, a print command such as print contents is sent to (see signal U ₃ ).

According to the above-described illustrated embodiment, the terminal scratches can be automatically treated, and all the operations from winding to the winding machine, terminal processing, labeling, and storage can be unattended. It is possible.

Then, as shown in FIGS. 10 and 11, the winding direction--
By rotating the bobbin 10 in the direction of arrow E, the terminal 33a drops from above as shown by arrow F, and is carefully guided by the chute-shaped guide 31 to the narrow area 32 below, where photoelectric The detector 34 such as a sensor can surely detect.

Further, as shown in FIG. 13, this narrow range
The terminal 33a that hangs down to 32 is securely grasped by the forward movement of the first chucking 35 (in the direction of arrow H), and then retracted, and the terminal 33a is moved from the bobbin 10 to the terminal as shown in FIGS. Since 33a is pulled out and stretched to a position where the second chucking 45 can be gripped and carried to the second chucking 45, loss winding by the loss winding drum 46 can be performed quickly.

In particular, since the second chucking 45 is formed on a part of the loss winding drum 46, the above-mentioned change-over process and the loss winding process can be performed quickly and smoothly.

The guide roll 58 has a function of narrowing the range R to which the label 64 is to be attached as shown in FIG. 19, and it is sufficient that the size of the label 64 is small.

Also, the terminal 33a is cut by the pressing roller 59 even after cutting by the cutter 56 (as shown in FIGS. 18 to 20).
Is reliably pressed and held, and the feeding extra length P ₁ is rewound so that the length from the label 64 to the tip end portion of the terminal 33a can be made extremely short.

This pressing roller 59 is labeled as shown in FIG.
It is possible to reliably attach 64 to the curved outer peripheral surface 33b.

When the bobbin 10 sent from the winding machine in the previous step has one type of wire winding direction, the turntable frame 20 shown in FIGS. 3 and 4 is unnecessary, A fixed structure may be used, and a single guide 31 may be used.

The carrying-in means and the carrying-out means may be robots or other various automatic machines other than the illustrated embodiment, and various arrangements and various bobbin flow directions may be freely changed. Further, the label sticking device 3 may also have a structure for sticking a label from above, below or obliquely.

[0078]

The present invention has the following significant effects with the above-mentioned configuration.

It is possible to automate the loss removal of the end portion of the electric wire cable wound on the winding bobbin and the label sticking, and completely unmanned from the winding machine in the previous process to the final stockyard. It is also possible to achieve significant labor savings.

Since the winding bobbin is rotated in the winding direction and is guided by the chute-shaped guide to the lower narrow area where it is detected by the detector, the terminal can be detected quickly and reliably. In particular, even if the terminal is wound in various states, it is possible to detect the above quickly and reliably.

At the position where the first chucking holds the terminal, the terminal is guided in a narrow area in advance and hangs down, so that the terminal can be easily held (grasped).

Since the winding drum has the second chucking, the terminal loss can be immediately (quickly) wound up as soon as the second chucking holds the terminal.

Between the take-up bobbin on the bobbin support and the loss take-up drum, the cutter cuts the middle of the end stretched in a straight line, so that the cutting can be performed surely and quickly. Subsequent terminal processing (eg labeling)
Is easy.
