Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an end processing device for a wire winder.

As a wire winding machine for winding wire objects such as electric wires, there are known wire winding machines that continuously wind the wire objects onto bobbins one after another without stopping the continuous running of the wire objects. .

Such a continuous winding machine usually has two winding bobbins, and when one winding bobbin is fully wound, the running of the linear object is not temporarily stopped (the running of the linear object is automatically stopped). and, at the same time as cutting, automatically winds the continuously running wire onto the other empty bobbin.

When the linear object is cut, the end of the cut linear object remains on the fully wound bobbin side with a predetermined length protruding from the bobbin.

The fully wound bobbin will continue to rotate for a predetermined period of time due to inertia even after cutting, but since tension is no longer acting on the cut end, the end will be wound onto the bobbin no matter how much the bobbin rotates. That's ℃・.

Therefore, the cutting end that remains freely protruding from the fully wound bobbin side is freely swung around until the fully wound bobbin stops rotating, causing a whiplash phenomenon in which it hits the already wound wire on the fully wound bobbin. In addition to damaging the product, it was extremely dangerous and could also damage surrounding equipment.

Therefore, the applicant of the present application proposed a means for solving the above problems in the specification of Japanese Patent Application No. 50-44404, and the present invention relates to an improvement thereof.

The object of the present invention is to make simple covers overlap each other through a simple operation process, and under the same condition, isolate the dough cutting terminal from the fully wound bobbin, and damage the terminal in the inner area of the cover. It is designed to be rolled up and stored smoothly without any problems.
In particular, it is designed to reliably wind the cut end through a more accurate so-called restraint route to the full winding side, and therefore, its feature is that it allows continuously running linear objects to be wound side by side. In a winding machine that winds the wire on one of a pair of winding bobbins, and when the bobbin becomes fully wound, automatically cuts the wire material and winds it onto the other empty bobbin, each of the pair of winding bobbins A cylindrical main end processing cover that can be externally fitted onto a fully wound bobbin, and a cylindrical auxiliary end processing cover that can be externally fitted onto the cover with a gap that allows a linear object to pass through. A terminal guide plate is provided on the outer peripheral surface of the main terminal processing cover and protrudes in the radially outward direction. A moving means is provided for moving the force bars of the bobbin on the fully wound side toward each other along the axial direction of the bobbin when cutting an object, and for stopping the approaching operation when the force bars overlap by a predetermined amount. In this state, a gap is formed between the overlap side end surface of the main end processing cover and the flange surface of the bobbin, and between the overlap side end surface of the auxiliary end processing cover and the end guide plate, through which a linear object can pass. The terminal guide plate has a concave portion formed in a portion facing the auxiliary terminal processing cover that bulges toward the opposite side of the auxiliary terminal processing cover.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

In Figures 1 and 2, a pair of left and right rotation 1 drive shafts 1
, 1' are arranged horizontally and in parallel with a predetermined distance apart.

A pawl wheel 2, 2' is attached to one end of the rotary drive shaft 1, 1'.
is fixed.

Supplementary claws 3, 3' are provided on the outer peripheries of the claw wheels 2, 2' to protrude radially outward.

Winding bobbins 4, 4' are removably inserted and fixed from the ends of the rotary drive shafts 1, 1' opposite to the claw wheels.

Flanges 5, 5', 6,
6' is formed, and one flange 6°6' is also used as pawl wheels 2, 2'.

The winding bobbins 4, 4' are rotated in opposite directions by the rotation 1 drive shafts 1, 11, and in the illustrated example, the left bobbin 4 in FIG. Rotate clockwise.

Which of the above two bobbins 4, 4' has the linear object 7 on one side?
is wound up.

The linear object γ is connected to both bobbins 4, 4 from above both bobbins 4゜4'.
' and is wound onto either one of the bobbins 4 or 4'.

In the illustrated example, the bobbin 4 on the left is being wound, and the left bobbin is an empty bobbin 4'.

The wire 7 is guided through a traverser sheave 8 arranged above the bobbins 4, 4'.

The traverser sheave 8 is capable of reciprocating along the axial direction of the bobbins 4, 4', and is also reciprocating in the left-right direction.

This traverser sheave 8 is located above the substantially central part between the bobbins 4 and 4' during winding of the wire material, and
reciprocates in the axial direction.

Due to this reciprocating motion, the linear object 7 is wound up spirally onto the bobbin 4.

When the bobbin 4 on the left becomes fully wound as shown in the figure, the traverser sheave 8 moves to the empty bobbin 4' on the right side in the figure.

This moving position is a position where the linear object 7 comes into contact with the body of the empty bobbin 4', as shown in FIG.

During this movement to the right, the traverser sheave 8 reciprocates in the axial direction of the bobbin 4, but when it approaches the pawl wheel 2' side, it stops at the same position (a in the figure).

The wire material 7 is thus cut and wound onto the empty bobbin 4', and these operations are performed by the main wire shifter lever 9.

This main line shift lever 9 is located between the bobbins 4 and 4', and is provided so as to be able to reciprocate in the axial direction of the bobbin 4 by means of a cylinder 10.

Normally, this main line shift lever 9 is on standby on the opposite side of the pawl wheels 2, 2', and upon receiving a signal that the traverser sheave 8 has reached position a, the main line shift lever 9 advances to the pawl wheel side. Operate.

As the main line shifting lever 9 advances, the linear object 7 between the bobbins 4 and 41 is pushed out toward the pawl wheel 2°2' side as shown in FIG. 3
’ is hooked by.

By this hooking, the wire material 7 is cut and is also wound onto the empty bobbin 4'.

The cut end protrudes from the fully wound bobbin 4 by a predetermined length.

The above-mentioned cutting and rewinding operations are automatically performed without stopping the linear object 70 from traveling.

When the above operation is completed, the traverser sheave 8 reciprocates in the axial direction and returns to its original position above the center between the bobbins 4 and 4', and at the same position it reciprocates in the axial direction to remove the empty bobbin 4.
Indignantly, I guided the linear object 7.

When cutting the above-mentioned wire material 7, in order to prevent the wire material 7 from getting caught in the claw 3 of the claw wheel 2 of the fully wound bobbin 4, and to ensure that the cutting end protruding by a predetermined length is smoothly attached to the fully wound bobbin 4. A main end processing cover 11 and an auxiliary end processing cover 12 are provided to enable the winding.

The main end processing cover 11 is a cylindrical body having an inner diameter that can be fitted onto the fully wound bobbin 4, and is normally placed coaxially with the bobbin 4 on the outer side of the bobbin shaft end opposite to the claw wheel 2. It is located.

This main terminal processing cover 11 is movable in the axial direction of the bobbin 4 by a cylinder 13 serving as a moving means, and can be freely fitted onto the fully wound bobbin 4 .

Note that this main terminal processing cover 11 is provided so as not to be rotatable.

On the outer circumferential surface of the axially midway portion of the main terminal processing cover 11,
A terminal guide plate 14 is provided that projects radially outward.

As shown in FIG. 2, this terminal guide plate 14 is provided so as to cover the side of the travel path of the linear material 7 at the time of cutting the dough.

That is, the amount of protrusion of the terminal guide plate 14 gradually changes so as to cover the tangent line from the outer periphery of the full bobbin 4 to the outer periphery of the empty bobbin 4'.
'It protrudes to a maximum at a position facing the center, and then gradually decreases as it moves along the rotational direction of the fully wound bobbin 4.

Incidentally, the reduction in the amount of protrusion of the terminal guide plate 14 was determined from the viewpoint of material saving and design, and does not affect the function.

The auxiliary terminal processing cover 12 is similar to the main terminal processing cover 11.
It is a cylindrical body that can be fitted externally with a gap through which a linear object 7 can pass, and has an inner diameter that allows the pawl wheel 2 to be fitted externally as well.

The auxiliary terminal processing cover 12 is normally disposed outside the shaft end of the bobbin 4 on the claw wheel side, coaxially with the axis of the bobbin 4 and unrotatable.

This auxiliary terminal processing cover 12 is also movable in the axial direction of the bobbin 4 by a cylinder 15 serving as a moving means, and can be fitted onto the fully wound bobbin 4 .

The main terminal processing cover 11 and the auxiliary terminal processing cover 12
is waiting outside the bobbin 4 while the wire material 7 is being wound onto the bobbin 4.

In conjunction with the advance movement of the main line shifter lever 9, the force bars 11 and 12 are moved by the moving means 13 and 15 so as to approach each other.

When the double force bars 11 and 12 overlap by a predetermined amount,
The approaching movement stops.

By this action of approaching the two-force bars 11 and 120, the linear object 7 is sandwiched between the tip surfaces of the two-force bars 11 and 12.

In the overlapping and stopped state, the end surface of the main end processing cover 11 on the overlap side faces the end surface of the claw wheel 2 with a gap that allows the linear object 7 to pass through.

The overlap side end surface of the auxiliary terminal processing cover 12 is
It faces the terminal guide plate 14 with a gap through which the linear object 7 can pass.

A recessed portion 16 is formed on the surface of the terminal guide plate 14 facing the auxiliary terminal processing cover, which bulges toward the side opposite to the auxiliary terminal processing cover.

The main terminal processing cover 11 and the auxiliary terminal processing cover 12 are also provided on the empty bobbin 4' side, and are shown with the same reference numerals and a dash in the drawings.

By winding up the wire material 7, this empty bobbin 4' also becomes fully wound, and each cover 11', 12
' operates in the same manner as the covers 11 and 12 described above.

According to the embodiment of the present invention, when the linear object 7 is moved toward the pawl wheel side by the main line shifting lever 9, the linear object 7 comes into contact with the tip of the auxiliary end processing cover 12 and is bent.

This contact prevents the wire 7 from being caught by the hook 3 of the fully wound bobbin 4.

When cutting with the claw 3' on the empty bobbin 4' side, the linear object 7
A large tension is applied to the material, and the tension becomes zero at the same time as cutting.

Therefore, during cutting, the linear object 7 that has been bent by the main line biasing lever 9 and the auxiliary end processing cover 12 exhibits a whiplash phenomenon due to the springback effect due to the disappearance of the tension.

However, this whiplash phenomenon in the bobbin axial direction is prevented by the end guide plate 14, and there is no fear that the cutting end will strike the already wound wire-like material of the fully wound bobbin 4.

At this time, the recess 16 at the tip of the terminal guide plate 14 effectively prevents the whiplash phenomenon.

That is, for example, if the terminal guide plate 14 is a straight plate, the terminal that is whipped in the bobbin axis direction is bent or bent at the tip of the guide plate, and the tip of the terminal goes beyond the guide plate and touches the wound wire-like object. There is a risk of hitting the surface.

However, as in the present invention, since the recess 16 is formed in the guide plate 14, the end that collides with the guide plate 14 from the axial direction of the bobbin is bent along the recess 16, so that the guide plate 1
It is no longer bent beyond 4, and the whiplash phenomenon is attenuated.

In addition, since the terminal is guided along the recess 16 at the tip of the terminal guide plate 14, frictional force is generated there and tension is generated on the terminal, so that the terminal cannot be caught by the fully wound bobbin 4 that continues to rotate due to inertia. become.

Therefore, it is possible to prevent the terminal from moving around while protruding for a predetermined length in the free state.

The terminal pulled into the auxiliary terminal processing cover 12 is
As shown by reference numeral 7a in the figure, the tip of the terminal slides around the inner surface of the auxiliary terminal processing cover 12.

Thus, the terminal is covered by the auxiliary terminal processing cover 12, the main terminal processing cover 11, and the terminal guide plate 14, and the already wound wire-like object is not damaged by hitting.

The terminal guide plate 14 reduces the lateral deflection of the linear object 7 during the terminal retraction, applies appropriate frictional force to the linear object 7, and contributes to smooth retraction.

Note that the present invention is not limited to the above embodiments.

According to the present invention, the following effects are achieved through the synergistic action of the main terminal processing cover, the auxiliary terminal processing cover, and the terminal guide plate.

■ The cutting end of the wire material will not hit the already wound wire of the fully wound bobbin.

- Since the cut end of the wire material is smoothly drawn into the auxiliary end processing cover without protruding and moving around, it is safe and does not damage surrounding equipment.

■ Due to the recess at the tip of the terminal guide plate, the terminal of the linear object will not be bent suddenly (it will be pulled in smoothly and the terminal will be prevented from scattering).
