Description

[Detailed description of the invention]

[0001]

[Industrial application field] The present invention automatically makes electrical wiring.
Wire feeding mechanism for this in automatic wiring equipment to perform
To the improved version.

[0002]

2. Description of the Related Art Electrical wiring of automobiles and electrical equipment.
In the field of manufacturing wire harnesses used for
Automation of wiring work for improvement has already been performed.
You. Wiring equipment to perform such tasks automatically
Information, running under computer control wiring robot
Can be said.

One of the robotized automatic wiring devices is
To move the flat panel in two horizontal axes.
Cable and a moving table placed on that table
And a flat board supported on the
Multiple pins rising from the board and the lifting platform
A platform for raising and lowering along the
To the elevator above the flat board and the lower part of the elevator.
A wiring nozzle that is attached and projects vertically below the elevator
Some have. When using this automatic wiring device,
Remove the wire that passed through the wiring nozzle from the top end of the wiring nozzle.
Move the flat board while pulling it down from the lower end of the wiring nozzle.
The electric table is moved by moving the table in two horizontal axes to flatten the wires.
Wrap around each pin on the board. Therefore, connect the wires to the specified wiring
It's a turn.

In the above-described automatic wiring device, the
Using a wire bundle in which wires are wound into a loop bundle, wire the wire bundle
Unwinding from the inner peripheral side of
It is common to do. What is important in supplying electric wires in this case
One of them is to prevent harmful twisting of the wire,
Another is not to break the bundle. Electric wire is twisted
The wire is properly wound around the pin.
The electric resistance of the wire increases at the twisted part.
Produces a condition. When the wire bundle collapses, the wires are easily entangled
It becomes.

[0005] It is possible to prevent twisting of an electric wire at the time of supplying the electric wire,
Preventing bundles from collapsing is a matter of existing wire supply mechanism.
Has also been done. A typical example is a turntable.
This is an electric wire supply mechanism. This type of wire supply mechanism
Has a central cone and outer wall set on the top of the turntable.
The space between the central cone and the outer peripheral wall is a space for holding the bundle of electric wires. With such a wire supply mechanism,
When supplying to a specified device, place it on a turntable.
Wire bundle set between the central cone and the outer peripheral wall
After that, rotate the turntable in the direction of unwinding the wire,
The wire unwound from the inner peripheral side of the wire bundle is
It is guided along an inclined surface and supplied in a predetermined direction.
The wire bundle in this case has an inner diameter as the wire is unwound.
To increase. And the inner diameter is larger than a certain value
From the beginning, it becomes difficult to maintain the self-form on its own
Want intends wire bundle that has become is break the alignment winding state. like this
In such cases, the central cone and outer peripheral wall support the inner and outer peripheral surfaces of the wire bundle.
To prevent its collapse.

[0006]

[Problem to be Solved by the Invention] This kind of electric wire supply mechanism
The center cone and the outside on the turntable
An electric wire bundle is set between the peripheral wall and the peripheral wall. The initial bundle of wires
Does not collapse because the winding volume of the wire is large and substantial
However, if the winding volume decreases with the supply of electric wires, the
Collapse as described. As a countermeasure against this collapse, a central cone
Keeping the body and outer wall in constant contact with the inner and outer peripheral surfaces of the wire bundle
Good. However, the inner diameter of the wire bundle always fluctuates.
In contrast, the diameter of the central cone and the outer peripheral wall does not change
Therefore, such double-sided contact support is not actually performed.
Therefore, the wire bundle collapses when the remaining winding of the wire is low.
Breakage, which often causes the wires to become tangled.
No.

Object of the Invention : The present invention solves such a problem.
Not only prevents twisting of the wires, but also
To provide an electric wire supply mechanism that is unlikely to collapse
Things.

[0008]

SUMMARY OF THE INVENTION An electric wire feeder according to the present invention.
To achieve the intended objectives, the following
Sign. In other words, the automatic wiring device
For winding wires around, wire bundle loops wires
When it is said that it is wound in a bundle,
Unwound from the inner peripheral side of the
In the wire supply mechanism used for
Underframe installed on the periphery and on the underframe assembled to the underframe
And a power rotary shaft protruding in the vertical axis

The space for holding the bundle is interposed, and the outside is held
For each convex linear member making up the body, one convex
The linear member has a vertical portion inside The vertical part is
Facing the inclined outer periphery of the holding body, the remaining multiple convex
Inclined part where the linear member slopes down from outside to inside
It has inside, and each of the inclined parts is inclined outside of the inner holding body.
Facing the periphery and the wires from bottom to top
Guide ring is attached to the support post
It is located on the upper side of the inner holding body, and the wire is automatically wired
A guide roller for guiding to the side is also attached to the support
It is characterized by being located above the guide ring.

[0009]

[Function] For the electric wire supply mechanism and the automatic wiring device,
The following preparations are made before the operation. Roof wire
The wire bundle wound in a bundle
It is set between the holder and the outer holder. In this way
The bundled wire bundle has the inner peripheral surface of the bundle
In addition to contacting the outer peripheral surface, the outer peripheral surface of the bundle also
It comes into contact with the surface. Unwinding from the inner circumference side of the wire bundle
At the unwinding end of the drawn wire, use a guide ring or guide roller.
To the automatic wiring device side via the
Being agitated or taken over. Wire supply mechanism and automatic
Wiring devices operate synchronously after completing these preparations.
State and the wire supply mechanism is synchronized with the wiring speed.
Supply the wire to the automatic wiring device side.

[0010] When the electric wire is supplied to the automatic wiring device side,
The wire supply mechanism is as follows. Automatic wiring device side
When the wire is pulled out of the wire bundle with the wiring in
In this case, the rotating shaft that receives the power rotation rotates in a predetermined direction.
The wire bundle support fixed to this also rotates in that direction.
You. At this time, the direction of rotation of the wire bundle support base forms the wire bundle.
The direction is reversed with respect to the winding direction of the electric wire. Therefore,
There is no twist in the wire unwound from the inner circumference of the wire bundle.
No. Then the wire is unwound from the wire bundle and the automatic wiring device
Side, the inner diameter of the wire bundle gradually increases.
It is getting better.

On the wire bundle support base, a substantially conical inner side

Faces the inclined outer periphery of the inner holder.
is there. The vertical part of the convex linear member circumscribes the wire bundle and
Support the peripheral surface. Each inclined part of the other convex linear member is a bundle of electric wires
To prevent the outer diameter from expanding. Therefore, the wire bundle
Inner and outer circumferences through inner and outer holders
Surface is supported and collapses when supplying electric wires
There is no fear.
