DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for continuously supplying a flexible linear object.

[0002]

2. Description of the Related Art In a method and an apparatus for continuously supplying a flexible linear body, for example, as shown in FIG. 18, a first coil A and a second coil B are arranged in an eyeglass shape, The end terminal of the first coil A is connected to the start terminal of the second coil B, and the start terminal of the first coil A has a circular cross section and is formed of an inclined material. The linear body W is supplied to the assembling step for assembling the linear body W through the movable wheel E and the covering step of applying an insulating coating, and the supply of the linear body W of the first coil A. Then, the pallet P on which the new coil wound with the linear body W is placed is placed at the place where the pallet P (the accessory of the coil A) on which the first coil A is placed is removed, and the start terminal is changed to the first terminal. 2 by connecting to the end of coil B There is a continuous supply method of the linear body W to be.

[0003] Here, a ring L is arranged close to the upper part of the coil so that the linear member W does not hit the flange of the bobbin and is not damaged. Also, a first coil A arranged in a spectacle shape
A conical hood F and a wheel E are integrated with the upper portion of the second coil B, and are reciprocated by being pulled and moved by a person via a string H.

As shown in FIGS. 19 and 20, a linear body 1 is attached to a bobbin 110 including a body 107 and a flange 108.
09 is wound, and a flyer 100 that is in contact with one flange 108 is installed. The ring portion 101 of the flyer 100 is formed slightly larger than the flange 108,
When the linear body 109 is extended, it does not hit the flange 108.

The ring portion 101 has a surface processed so as to be slippery when the linear body 109 is fed around the circumference thereof, and a plurality of flexible bodies such as hard nylon, for example, which are radially formed. 102 is, for example, an adhesive tape 1
It is fixed at 05. The hanging member 103 has a weight 1
04 is fixed to the flyer 100 and used for transportation. Such a flyer 100 is adapted to the diameter size of the linear body and the linear velocity when the linear body is fed out, but when the line size changes or the linear velocity changes, the conditions are satisfied each time. There was a limit to procuring the right one.

[0006]

When manually moving a conical hood as shown in FIG. 18, the timing of the movement is extremely important. That is, if the timing of the movement is delayed, the linear body W comes into contact with the lower end of the circular pushing hood F so as to be sharply bent, so that the linear body W may be broken. Or, even if it does not break, the linear body W
May be rubbed by the conical hood F to cause scratches on the surface. For this reason, for example, when the linear body W moves from the empty first coil A to the second coil B, the conical hood F must be immediately moved. However, it was difficult to improve the work efficiency because the worker was in a so-called nailed state, the work was restricted, and the linear velocity had to be reduced before and after the movement.

In the case of using the feeding device shown in FIGS. 19 and 20, when the diameter of the linear body or the linear velocity at the time of feeding the linear body changes, it is possible to sufficiently follow the linear body. Since it was not possible, it was necessary to readjust it again and to limit the linear velocity, so that it was difficult to increase the production efficiency. Also, in order to change the type of processing, sometimes the feeding of the linear body is stopped, but at that time, the linear body may fall apart from the surface of the coil and fall, and then when the linear body is fed again, When the linear bodies dropped and fallen were entangled with each other, the linear bodies could not be extended and could be disconnected.

Further, the wire cannot be fed even if the wire is separated and dropped due to the force of the wire feeding, so that the surface may be damaged or the wire may be broken. According to the study by the inventors, as the working range of the wire diameter and the wire speed of the linear body is expanded, in the feeding device shown in FIGS. It was found that it was necessary to rotate the tension stably to prevent accidents. However, on the other hand, an appropriate torque is required even when rotating.

[0009]

And an oval hood having a cross section at the start end of the first coil and formed of an inclined material and a wheel for guiding a linear body, the wheel being capable of moving within an upper opening of the oval hood. After supplying the linear body through the first coil, after supplying the linear body of the first coil, the coil wound with the linear body is placed at a place where accessories of the first coil are removed, and the start terminal is set to the The linear body is supplied by connecting to the end terminal of the second coil.

Further, the flexible body protruding into the oval hood may be pushed or bent, or the flexible body radially arranged in close proximity to the coil on the feeding side of the linear body may be pushed and bent by the linear body. A tension is applied to the linear body so that the linear body of the coil does not fall apart and fall when the linear body is resupplied. In addition, the impact of the linear body on the inner wall of the hood is reduced, and there is an effect of preventing generation of scratches on the wire surface and prevention of fluctuation in tension. Furthermore, whether the coil linear body is right-handed or left-handed (even if the coil is upside down)
It is configured so that it can be fed out as it is.

Further, the present invention relates to a linear body connecting the end terminal of the first coil and the start terminal of the second coil, or the start of a coil wound around the linear body with the end terminal of the second coil. The linear body connected to the terminal is locked, and the wheel is moved by a signal released by the linear body being unlocked.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In a method and an apparatus for continuously supplying a linear body according to the present invention, a first coil A and a second coil B are arranged in an eyeglass-like manner, for example, as shown in FIGS. Then, the end terminal of the first coil A and the start terminal of the second coil B are connected with a normal butt welder, a cold welder, or the like, and the start terminal of the first coil A is formed into an oval long section. The linear body W fed from the coil and the elliptical hood 1 formed by the inclined member 4 and the coil is guided, and the linear body W is supplied to, for example, an extruder or a collective machine via a movable wheel E.

After the supply of the linear body W of the first coil A is completed, the pallet P (the coil A
Is removed, and a pallet P on which a new coil C wound with a linear body W is placed is placed at the place, and the start terminal is connected to the end terminal of the second coil B, thereby continuously. The continuous supply of the linear body W to be supplied is enabled.
Here, the flyer 20 is arranged close to the upper part of the coil so that the linear body W does not hit the flange of the bobbin and is not damaged. As shown in FIGS. 3 to 12, the flyer 20 includes a rotating ring 24, a rotating brush 26, and a rotating brush brake 28 for controlling the rotating brush 26.

In FIG. 2, between the first coil A and the second coil B arranged like glasses, it is notified that the first coil A is empty, and that the first coil A is newly extended from the coil B. The switching transmitting device 50 for generating a signal is fixed to the floor FL and the linear member W is locked to the locking member, and the locking member is displaced by lifting the linear member W. Therefore, a signal is generated by this displacement.

The elliptical hood 1 is formed by continuously forming a semicircle at both ends of two straight lines parallel to each other in both the upper opening 2 and the lower opening 3, and forming the upper opening 2 and the lower opening 3 into inclined materials. 4, the inner surface of the oval hood 1 is made of a plastic material so as not to damage the linear body W. Further, a plurality of flexible bodies 5 are attached to the inner surface of the oval hood 1 so as to protrude toward the inside. The flexible body 5 has a length of 20 to 30c.
Hard nylon having a diameter of about m and a diameter of about 2 to 3 mm is used. Hard nylon does not cause damage to the linear body W by its nature, and because it is so-called stiff,
Can be used stably for a long time. In addition,
The elliptical hood 1 is composed of two inclined materials 4 whose surfaces are arranged in a plane.
It may be divided into stages.

Each of the coils A and B has a hollow central portion. As shown in FIG. 3, a middle cylinder 15 is inserted into the hollow portion, and the flyer 2 is mounted thereon.
0 is attached. As shown in FIGS. 4 to 8, the flyer 20 has a circular plate member 21 at a lower portion of the flyer 20, an insertion member 22 inserted into a hollow portion of the coil at a lower surface thereof, and an upper surface at an upper surface thereof. The shaft rods 23 are respectively fixed. The rotating ring 2 is arranged on the shaft 23 in the order from the plate material 21.
4. The rotating brush 26 and the rotating brush brake 28 are integrally formed, and the rotating ring 24 and the rotating brush 26 are rotatably mounted in two directions, clockwise and counterclockwise.

The rotating brush 26 has a large number of flexible members 26 'attached to its circumference so as to be oblique so as to contact or approach the outer periphery of the rotating ring 24. The flexible body is made of hard nylon having a length of about 20 to 30 cm and a diameter of about 2 to 3 mm. Hard nylon does not cause damage to the linear body W by its nature, and has a strong so-called rigidity, so that it can be used stably for a long period of time.

The wire W is fed out while being in contact with the rotating brush 26. When the feeding of the wire W stops, the wire W assumes a gentle spiral state. For this reason, the wire W in the middle of the feeding is the flexible body 26 ′ of the rotating brush 26.
And will not fall near the coil. In order to prevent the wire W from dropping near the coil, as shown in Table 1, even if the number of brake brushes is too large, such as 80 or more, or a few brush brushes, the appropriate supply Since it is empirically known that this cannot be done, it is necessary to set the optimum conditions. However, the present invention is a simple device that can be easily adjusted.

[0023]

[Table 1]

The rotary brush brake 28 has its own brake plate 27 fixed to the shaft 23, does not rotate, and bends and inserts the brush 28 'into a hole 31 formed in the brake plate 27. Has been fixed by that. This is because the flexible body has elasticity, so that the flexible body is firmly fixed to the hole 31 by bending. A plurality of brushes 28 ′ made of hard nylon fixed radially to the rotating brush brake 28 in the circumferential direction are frames 25, which constitute the rotating brush 26.
The rotation of the rotating brush 26 is appropriately controlled by contact with the rotating brush 26.

The brush 28 'made of hard nylon and mounted on the rotary brush brake 28 is inserted into the detachable hole 31 as described above, and the number of brushes is appropriately adjusted so as to meet the conditions shown in Table 1. The torque as a brake can be adjusted by selecting or inserting it into a hole 31 having a different distance from the center. 32 is a hole in which the brush is inserted. In addition, since the rotary brush 26 rotates while following the linear body W in either of the right and left directions, there is no restriction on the rotation direction.

By the way, the brush rotating force F to the rotating brush 26 caused by the unwinding of the wire W can be approximated by a horizontal component of the force applied to the rotating ring 24 by the wire W. Therefore, F∝m × r × ω ² ... (A). Here, assuming that mass: m∝ wire diameter ² = φ ² turning radius: r = constant rotation speed: ω 巻 wire speed / winding diameter = v / D, F∝ (A) ∝φ ² × v ² × D ^-2 ... (B) holds.

Here, as shown in FIG. 9, the wire W to be fed out can be represented by a substantially straight line from the coil to the rotating ring 24 and from the rotating ring 24 to the guide G. Now, as shown in FIG. 10, the coil width is 0.7 m, the vertical distance from the rotating ring (considered the same as the upper end of the coil) to the guide G is 2.2 m, and the radius of the rotating ring (rotation radius) Is 0.6 m, the angle θ1 formed by the wire W connecting the rotating ring 24 and the guide G with the horizontal line is θ1 = 7.
5 °. When the wire W is fed out from the upper end of the coil, it is fed out almost horizontally, so that θ2 = 0 °
It has become. Therefore, the horizontal component and the vertical component of the wire W at that time are, as shown in FIG. 11, the horizontal component of the vector F (upper): (1 + cos θ1) T = 1.
26T Vertical component of vector F (top): Tsin θ1 = 0.97T
Becomes

On the other hand, the angle at which the wire W is fed out from the lower end of the coil is θ2 = 49 °, as shown in FIG. 12, and the wire W connecting the rotary ring 4 and the guide G is at an angle with the horizontal line. Since the angle θ1 = 75 ° does not change, the horizontal component and the vertical component of the wire W at that time are the horizontal component of the vector F (lower): (cos θ1 + cos θ2) T =
0.91T Vertical component of vector F (lower): (sinθ1−sinθ2) T =
0.21T.

Therefore, the variation ratio of the horizontal component of the wire W fed from the upper end and the lower end of the coil is 1.26 T /
0.91T = 1.38. Therefore, it can be seen that it fluctuates within a range of about 40%. Table 2 shows the results of investigations based on actual specific examples of the expected values when the wire diameter φ, the wire speed v, and the winding diameter D change. Here, in the case of “the wire diameter is large and the linear velocity is also large”, the absolute amount of the flash rotational force F increases as the square and the fluctuation increases. Occurs,
Focusing on the fact that it is always better to keep the brakes in an appropriate stopping state, as this may cause the sag,
8 is provided. Needless to say, the angles θ1 and θ2 are appropriately determined depending on the feeding state of the wire W.

[0030]

[Table 2]

The switching transmitting device 50 is, as described above,
Detects the linear body W that has been unreeled from the bobbin. By detecting that the linear body W has been lifted, the linear body W issues a signal for moving the wheel E. For example, FIG. 13 to FIG. There is something like that shown. The switching transmitting device 50 shown in FIGS.
Lifts the lever 56, which is a locking member, so that the contact point 54 of the limit switch 52 is lifted.
A signal is issued, and the movement of the wheel E is started by the signal.

Here, 51 is a base, 53 is a hinge, 55
Indicates a contact material. However, the switching transmission device 50 determines that the linear body W of the unwinding bobbin is empty when the linear body W is inserted by lifting the lever 56 serving as a locking member. As a result, a signal for moving the wheel E is issued, and it is necessary to configure an electric circuit so that the wheel E does not move by a signal when the linear body W is inserted by electric control. Alternatively, the connecting operation may be performed after the linear body W that has not been connected yet passes through the switching transmitting device 50. In this case, when attaching the continuous linear body W, a signal is generated. There is no.

The switching transmitting device 50 ′ shown in FIGS. 15 and 16 has a shaft 62 mounted on a frame 62 fixed to a base 61.
A rotating member 71 pivotally connected via the first arm 0 is provided, and the upper arm 65 and the lower arm 66 are integrally formed on the rotating member 71 serving as a locking member. A projection 68 is fixed to the rotating member 71, a projection 67 is fixed to both sides of the frame 62, and a spring 69 is attached to the projection 67 and the projection 68 in a pulling direction.

Reference numeral 63 denotes an arc frame on which a limit switch 64 is fixed. The switching transmitting device 50 ′ is configured to prevent a signal from being generated to the wheel E when the linear body W is inserted. When the linear body W raises the upper arm 65, the limit switch 64 is switched.
, The movement of the wheel E is started, but the upper arm 65 is stopped in a state of being lifted. By pressing down the lower arm together with the continuous linear body W connected and connected in this state, the linear body W raises the upper arm and obtains a signal opposite to the signal generated in the limit switch even if the linear body W is set again. This can be used as a reset signal to enable the movement of the wheel E.

Assuming that the coil has a net weight of 3.3 tons, for example, if the wire W is supplied at a speed of 220 m / min per minute with a copper wire diameter of 1.6 mmΦ, switching is performed once every about 14 hours. In addition, if the wire W is supplied at a diameter of 2.6 mmΦ at a wire diameter of 150 m / min, the switching is performed once in less than about 8 hours. Therefore, the switching frequency is extremely low. Therefore, the monitoring work for the switching work is not advisable from the viewpoint of work efficiency, and it is extremely effective to provide the switching transmitting device 10 and perform the automatic switching.

FIG. 17 shows a schematic configuration of a moving device provided above the oval hood 1 for moving the wheel E in response to a signal from the switching transmitting devices 50 and 50 '. A guide G for guiding the linear body W integrally with the guide shaft is mounted in the vicinity, and is reciprocally slidably fitted to, for example, a square shaft 86 and fixed to the belt 84. The belt 84 is a motor 81
When the wheel 83 fixed to the rotating shaft 82 rotates,
The wheel E is suspended over the wheel 83 and the idle wheel 83 ′, and the wheel E reciprocates by the rotation of the motor 81.

The belt 84 is provided with a projection 87, which moves by a predetermined distance by stopping the rotation of the motor 81 by contacting the left and right limit switches 88, 89. Further, after removing accessories such as the pallet of the emptied coil C, a new coil C is connected to the wire W, and the wire C is loaded into the switching transmitters 50 and 50 '. When the body W is switched, the wheel E moves to the original position. As a result, reciprocation is performed, and such movement is repeated thereafter.

[0038]

According to the present invention, the first coil and the second coil are arranged in a spectacle shape, and the end terminal of the first coil is connected to the start terminal of the second coil.
The start end of the first coil is guided by an oval hood having a cross section of an oval shape and formed of an inclined material and a linear body, and a tangential line is supplied through a wheel movable in one surface of the trapezoid. At the same time, after supplying the linear body of the first coil, the coil wound with the linear body is placed at a place where the first coil has been removed, and the start terminal thereof is connected to the end terminal of the second coil. Since the linear body is supplied by this, continuous supply can be performed.

The flexible body protruding into the oval hood may be pushed or bent, or the linear body may be pushed and bent by radially arranging the flexible body in close proximity to the coil on the feed side of the linear body. Since the tension is applied to the linear body, when the linear body is resupplied, since the linear body of the coil does not fall apart and falls, the linear body does not become entangled and broken. . In addition, the impact on the inner wall of the hood of the linear body is reduced,
This has the effect of preventing scratches on the wire surface and preventing tension fluctuation.
Furthermore, the coil can be fed out as it is regardless of whether the coil is wound right or left. Since the flexible body is hard nylon, the linear body does not fall due to bending, and has a characteristic durability of the hard nylon. Can be used.

Further, since a rotating brush in which flexible bodies are radially arranged in proximity to the coil on the feeding side of the linear body and a brake means for braking the rotating brush are provided, the tension of the linear body is stabilized. Since the wire is not separated from the coil even in the stopped state, it does not break even if the linear body is drawn out again. The brushes radially arranged on the rotating brush are further inclined to be close to the rotating ring, so that the linear body can be close to the brush, so that the linear body can be prevented from falling and the line size and the size can be reduced. It can follow changes in the linear velocity. Since the brake means makes the rigid body of rigid nylon fixed to the fixed frame contact the frame of the rotating brush, the extending direction may be left or right, and the brake means can be used stably for a long period of time.

Still further, the present invention relates to a linear member connecting the end terminal of the first coil and the starting terminal of the second coil, or a linear member connected to the end terminal of the second coil. Since the linear body connected to the starting terminal is locked and the wheel is moved by the signal released by the linear body being unwound, the linear body is moved from the first coil. It is not necessary to keep an eye on the moment when the operation is shifted to the second coil, so that the work efficiency can be improved.
