DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for attaching a label to a terminal of a winding bobbin.

[0002]

2. Description of the Related Art In the process of insulating and extruding an electric wire cable called a thin cable having a diameter of 3.0 mm or less, a winding bobbin which is insulated and wound by a winding machine is treated as a terminal. It is necessary to cut and remove a predetermined length as a terminal loss, and then fix a terminal after cutting by attaching a label.

[0003]

Conventionally, the above two steps are difficult to automate and have been performed by an operator.

[0004] Therefore, it has been a bottleneck in automating the entire process.

[0005]

According to the present invention, a winding bobbin in a fully wound state is rotatably held, and an outer peripheral surface of an electric cable wound around the winding bobbin by a pressing roller is extended over a predetermined width. While pressing, the end of the wire cable is cut in the middle of the loss winding drum and the winding bobbin, and the extra length from the cutting point to the vicinity of the point pressed by the pressing roller is determined by the pressing. After continuing to rewind to the winding bobbin while continuing,
This is a method in which a label is stuck by an automatic label sticking apparatus, and the winding bobbin is driven and rotated while the pressing is continued, so that the label is crimped along the outer peripheral surface of the wound wire cable.

[0006]

[Function] Since the cutting is performed while pressing with the pressing roller, the slack of the terminal does not spread to the electric cable wound around the winding bobbin. In addition, the length from the label to the final end of the electric cable after the label is applied is short and convenient (it does not hinder the subsequent handling of the winding bobbin) since the extra length of the feeding is rewound.

[0007] Further, by pressing the outer peripheral surface of the wound wire cable with a pressing roller, the label is securely crimped along the curved surface.

[0008]

As shown in FIG. 13, this is a position where the terminal 33a hanging down through the narrow area 32 (as described above) can be pinched.

The position of the movable table 39 shown by the solid line in FIG. 4 and FIG. 15 is the retreat position, and the electromagnetic clutch shown in FIG.
If the movable table 39 is retracted in the direction of the arrow I while holding the terminal 33a from the bobbin 10 on the idle rollers 23 with the 27 turned off, the bobbin 10 moves in the direction opposite to the arrow E. It idles and the terminal 33a is pulled out and comes to the J position in FIG. 15 and FIG.

Reference numeral 45 denotes a second chucking (possible) located in the middle of the J position, which is attached to a part of the loss winding drum 46.

The loss winding drum 46 is a drum for winding, as a terminal loss, the terminal 33a over a predetermined length, which is likely to be damaged in the insulating extrusion process and the winding process in the preceding process.

The loss winding 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 in the power transmission system.
49 are interposed. The drum 46 has a notch 51 at a part of the circumference of one flange 50. This notch 51
, A guide rod 53 protruding from the holding piece 52, and a second chucking 45 comprising a reciprocating mechanism (not shown in detail) such as a solenoid or a fluid cylinder. The flange 50 is provided at the position of the notch 51.

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 deployable radial holding plates 55... 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 pulled out terminal 33a passes between the notch 51 and the holding piece 52 in the open state (see FIG. 15).

When the second chucking 45 is closed in the direction of arrow K, as shown in FIGS. 16 and 17, the end 33a is held between the inner edge of the notch 51 and the outer edge of the holding piece 52. Wearing (gripping).

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

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

Reference numeral 56 denotes a cutter, which is in the vicinity of 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, when the actuator 57 is not in use, the actuator 57 retracts to the side and outside.

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

A press roller 59 is attached to the turntable frame 20 in a horizontal and horizontal direction. The holding roller 59 is provided with an actuator 60 such as a fluid pressure cylinder.
The wire cable wound around the winding bobbin 10 as shown in FIG.
33 by pressing the outer peripheral surface 33b over a predetermined width.
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, the loss winding drum 46 is rotated in the direction of the arrow L by the preset number of rotations of the bobbin, and while traversing the guide roll 58, the terminal having a predetermined length is rotated. 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. .

The 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, when 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 and the winding bobbin 10 is rotated in the direction of arrow T, so-called temporary 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.

By the way, as shown in FIG. 8, each of the above-described devices is controlled by a main control circuit 66 for controlling a winder for winding after the insulating extrusion step, and an auxiliary control circuit 67 in conjunction therewith. .

That is, from the main control circuit 66 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 terminal flaws 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 FIG. 10 and FIG.
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 changing 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, so that the size of the label 64 is sufficient even if it 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.

If the bobbin 10 sent from the winder in the preceding process has only one type of 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.

[0072]

According to the present invention, the state in which the electric cable is wound around the winding bobbin without loosening can be maintained. In addition, since the label is firmly attached to the outer peripheral surface, it is possible to prevent the terminal from being accidentally detached.

Further, the length of an unnecessary portion of the terminal protruding from the sticking label is extremely short, so that there is no trouble in handling the bobbin thereafter.
