Strictly speaking, the inner edge of the notch 51 of the flange 50 itself also constitutes a part of the second chucking 45.

In the illustrated example, the other flange portion 54 is composed of a plurality of foldable and expandable radial holding plates 55... When the wound terminal loss becomes almost full, the folding portion 54 is folded. Thus, the terminal loss can be easily removed.

In FIGS. 4 and 15, such a loss winding drum 46 is slightly rotated to stop the second chucking 45 in the J position in advance, and as shown in FIG. This second
The chucking 45 is kept open, and then I
When the holding pieces 52, 52 of the first chucking 35 are retracted in the direction, the terminal 33a that has been naturally drawn out (as shown at the J position) passes through the second chucking 45.

That is, the drawn-out terminal 33a passes between the notch 51 and the holding piece 52 in the open state (see FIG. 15).

Then, when the second chucking 45 is closed in the direction of arrow K, as shown in FIGS. 16 and 17, the terminal 33a is sandwiched by the inner edge of the notch 51 and the outer edge of the clamping piece 52. Wearing (gripping).

Next, as shown in FIG. 17, the loss winding drum 46 is driven to rotate in the direction of arrow L. At this time, the clutch 27 shown in FIG.

This prevents the adhesive from coming off, and performs the below-described label pressure bonding operation.

By the way, as shown in FIGS. 17 and 18, while rotating the loss winding drum 46 in the direction of the arrow L by the preset number of rotations of the bobbin, and traversing the guide roll 58, a terminal having a predetermined length is formed. Wind up Ross.

Next, winding is stopped and the clutch 49 on the winding side is stopped.
Is released, the clutch 27 on the sending side is closed, and the guide roll 58 is set at the origin {in FIG.
And the take-up bobbin moves to the upper side in the width direction center plane Q.

Thereafter, in FIG. 18, the winding bobbin 10 is rewound about two or three turns (rotates counterclockwise). Since the guide roll 58 is at the origin, the end 33a of the electric wire cable 33 comes to the range R in the width direction indicated by oblique lines in FIG.

Then, the actuator 60 is extended and the pressing roller 59 is raised to fix the outer peripheral surface 33b of the wire cable 33 wound as shown in FIG. 18, and the terminal 33a is cut by 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 further unwound on the winding bobbin 10 as an extra length. That is, rewinds the feeding extra length P ₁ to the vicinity of the pressure point 62 of the pressing roller 59 (see FIG. 20).

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

Therefore, the automatic labeling 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 attachment position to the final end of the terminal 33b is slightly smaller.
{The rotation center angle of the bobbin 10 is more than 90 degrees}.

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 attaching device 3 has a function of automatically printing the type, dimensions, and material of the electric wire cable 33 and various data such as the name of the manufacturing plant and the date of manufacture on the label 64.

As shown by the imaginary line and the solid line in FIG. 20, the height position of the pressing arm 65 for pushing the label 64 is steplessly variable and can correspond to the size of the bobbin 10.

Thereafter, the pressing arm 65 of the automatic label attaching apparatus 3 is retracted, and the pressing by the pressing roller 59 is continued as shown in FIG. 21 to rotate the winding bobbin 10 in the direction of the arrow T. Label 64 that has been crimped is the outer peripheral surface
Crimping is ensured along 33b.

As is apparent from the above, the pressing roller 59 is
The action of holding the terminal 33a so that it does not come apart, and the label 64
Is performed.

As shown in FIG. 8, each of the above-described devices is controlled by a main control circuit 66 that controls a winding machine that performs winding after the insulating extrusion step, and a sub-control circuit 67 that works in conjunction therewith. .

That is, the main control circuit 66 switches to the sub control circuit 67
The winding direction of the bobbin, and the signal U ₁ of the bobbin position, etc. is sent, the reverse, the terminal processing unit 2, a label sticking apparatus 3, carrying means 1 and unloading unit 4, and the signal U of the bobbin position such ₂ is sent.

In particular, the sub-control circuit 67 sends the label attaching device 3
To, it is of course possible to apply an instruction of labeling timing, and sends the print command such as print content (the reference signal U _3).

According to the above-described embodiment, the processing of the terminal flaw can be automatically performed, and the operations from winding by the winding machine, terminal processing, labeling, and storage can all be unmanned. 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 falls down from above as shown by arrow F, and is skillfully guided by a chute-shaped guide 31 to a narrow area 32 below. The detector 34 such as a sensor can surely detect.

Further, as shown in FIG.
The terminal 33a hanging down from the terminal 32 is securely grasped by the advance of the first chucking 35 (in the direction of arrow H), and then retracted, and the terminal 33a is moved from the bobbin 10 as shown in FIGS. Since the 33a is pulled out, stretched to a position where the second chucking 45 can be gripped, and is changed 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 in a part of the loss winding drum 46, the above-described holding step and the loss winding step can be performed quickly and smoothly.

The guide roll 58 acts to limit the range R to which the label 64 is to be attached, as shown in FIG. 19, and it is sufficient if the size of the label 64 is small.

After the cutting by the cutter 56 (as shown in FIGS. 18 to 20), the terminal 33a
It is reliably pressed and held, and the feeding back up the excess length P _1, the length from label 64 to the leading end of the terminal 33a may be very short.

The pressing roller 59 is provided with a label as shown in FIG.
64 can be securely attached to the curved outer peripheral surface 33b.

When the bobbin 10 sent from the winder in the preceding process has only one kind of winding direction of the electric cable, 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 and other various automatic machines other than the illustrated embodiment, and may be freely changed in various arrangements and various bobbin flow directions. Further, the label attaching device 3 may have a structure in which a label is attached from above, below, or diagonally.

[0074]

According to the present invention, it is possible to automate the removal of the loss of the terminal portion of the electric cable wound around the winding bobbin and the label attachment,
From the winder in the previous process to the final stock yard, it is also possible to completely unmanned, and it is possible to achieve significant labor savings.
