Description

[Detailed Description of the Invention] [Background and Objectives of the Invention] The present invention relates to a new method for preventing wire breakage due to wire tangles, etc., in a shoulder width delivery device for delivering coiled copper wire, for example, in an electric wire manufacturing device. It is something.

BACKGROUND ART Conventionally, a shoulder-width delivery device has been frequently used as a device for delivering a filamentous body such as an electric wire.

This device consists of a coil stand (beam shaft) that accommodates a coil-wound filament, and a turn kite roll located above the coil stand to pull up and guide the filament.

By the way, in this conventional device, if the coiling state of the filament is poor and tangles occur in the filament, the tangled portion passes through the turn guide roll and reaches the main body of the machine such as a wire drawing machine. , the wire could be disconnected.

In addition, if a portion of the filament with poor coil winding does not lift up and becomes entangled with the coil stand, tension may be applied to the filament and the wire may break.

In order to operate the machine again in the event of a break in the wire, it is necessary to reconnect the wire to the machine body from the beginning, which is very time consuming.

In this way, if a large tension is applied to the wire between the coil stand and the main body of the machine due to poor winding of the coil or when changing the coil stand, the wire will break. It is preferable to perform an emergency stop before the wire breaks to prevent the wire from breaking.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for preventing wire breakage in an m-transport device, which eliminates the drawbacks of the prior art described above and prevents wire breakage due to high tension applied to the filament between the coil stand and the machine body. .

[Summary of the invention]

That is, the gist of the present invention is that a filament coiled on a coil stand passes through a turn guide roll provided above the coil stand, changes its feeding direction, and sends it out to the machine body. In the beam shaft delivery device, the turn guide roll is attached to a bracket having an elongated size provided in the composite direction of the force in the artificial side direction and the exit side direction of the filament body passing through the turn guide roll. The shaft of is fitted and supported,
A spring is applied to the elongated hole to push the turn guide roll upward in the direction opposite to the direction of the resultant force, and when tension is applied between the population side and the outlet side of the turn guide roll, the turn Breakage prevention of a beam shaft delivery device characterized in that the kite roll is pushed down in the direction of the resultant force of the above forces against the spring force, and the machine body is stopped by detecting the movement of this turn kite roll. It's in the method.

If the wire breaks between the coil stand and the machine body, it is most likely due to the coil getting tangled or the crossover wire getting caught when changing the coil stand, or due to a defect in the wire itself, such as a scratch. , there are almost no disconnections due to foreign matter, etc.
The present invention does not prevent wire breakage due to failure of the filament itself.

〔Example〕

Next, as an embodiment of the present invention, an insulated wire manufacturing apparatus for drawing 11 coiled wires and extrusion coating the outer periphery with an insulator will be further described with reference to the accompanying drawings.

In FIG. 1, the core vA2o sent out from the coil 2 of the coil stand 1 passes through the guide vibe 5, its direction is changed by the turn kite roll 4, and is supplied via the guide roll 7 to the wire drawing [8, not shown in the figure. However, the outer periphery of the core wire 20 drawn by the extruder is coated with an insulator.

3 is a bracket that supports the guide vibe 5 and the U-turn guide roll 4, and is moved in the direction of the arrow by an air cylinder 6. If the first coil of one coil stand is lost due to movement, the other coil is removed. The stand is switched to a coil.

FIG. 2 shows the iYi thinness of the bracket 3. The bracket 3 is provided with an elongated hole 31, into which the shaft 41 of the turn guide roll 4 is fitted and supported. A guide vibe 5 is supported in the artificial side direction F1, and a cover 10 for preventing line deviation is provided on the outer periphery of the turn guide roll 4.

The elongated hole 31 allows the filament 2 to pass through the turn guide roll 4.
0, in the composite direction F3 of the forces in the population side direction Fl and the exit side direction F2.

Then, the filament 2 between the inlet side direction Fl and the outlet side direction F2
When tension is applied to the wire drawing machine 8, the turn guide roll 4 moves in the F3 direction along the long hole 31, and the detector 13 shown in FIG. This prevents the strip 20 from breaking.

The detector 13 detects the axis 4 of the turn guide roll rule 4.
When the moving distance of the detection plate 14 provided on the slide ball bearing 11 provided at the base of the slide ball bearing 11 exceeds a predetermined distance, a detection signal is generated and sent to the control circuit (not shown in the diagram) to trigger an emergency event. It performs a q-stop.

As shown in FIG. 4, the slide ball bearing 11 is used to smoothly move the shaft 41 of the turn guide roll 4, which is fitted into the elongated hole 31, along the elongated portion 31. bearing 16 and spacer 1
7.

12 is a spring for limiting the moving distance of the slide ball hair ring 11, and the slide ball bearing 1
1, and is held between a spacer 17 and a bearing 16.

The moving distance of the turn guide roll 4 is the overlap 1 of the disc spring 12.
1;/p It is determined by the alignment, and the necessary spring force can be obtained by aligning the springs in the same direction for the force and in the opposite direction for the travel distance. .

In other words, the deflection δn+m of each disc spring 12 is f
Kg, if X1 sheets are stacked in the same direction, fto
tal= f ・XIKg, δtotal=δmm, when combining two X sheets in different directions, f total =
f Kg−δtotal=δ·X2mm.

To give concrete numerical values of this example, the angle between the inlet side F1 and the outlet side F2 of the core wire 20 is 90'', the resultant direction when high tension is applied is θ=45°, and F3=F1・F
2 cos θ.

For example, f = 8.24Kg, δ = O, 675n+m
If we use a disc spring of F3= f total
= 60 and g to make L-δtotal = 10mn+, Xl = 60/8.2/I Lr? ,×2=
1070.675ξ15, that is, 15 sets of 7 layers stacked in the same direction should be arranged in different directions.

In this way, if the blood spring is used, the tension and the moving distance can be arbitrarily selected, and it is advantageous because it can be arbitrarily adjusted to the detection signal of the detector 13 when the filament body 20 is disconnected.

Spring force that opposes tension is not limited to the disc spring 12:
An I-il spring or the like may also be used.

The guide vibe 5 is a thin cylindrical cane, and the entanglement of the coil 2 is caught in front of the turn guide roll 4, and high tension is applied to the turn guide roll 4. 1-Is it for long-term use? A bearing 5J with a seal at the tip is installed to prevent the occurrence of .

The detector 13 is fixed to the bracket 3 via a mounting plate 19, as shown in the fifth UA.

:1. For the detection H;;+3, it is preferable to use a non-contact type because vibrations, shocks, etc. will not cause malfunction, and types such as electrostatic capacitance type, 1t, single frequency emitting type, magnetic type, and photoelectric type are used. be done.

Note that the detector 13 is not limited to a non-contact type, and may be a contact type detector such as a limit switch.

In the above description, only one embodiment of the method of the present invention has been described, but it goes without saying that the present invention is not limited to this embodiment.

〔Effect of the invention〕

As explained above, according to the present invention, when a predetermined tension is applied between the inlet and the outlet of the turn kite roll, the machine is brought to an emergency stop, so there is no breakage of the wire, and there is no need to re-hang the wire Lj due to breakage. It saves time and improves manufacturing efficiency, and has great industrial value.
