BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing entanglement and breakage of a filament material, and more particularly, to a method for tangling a filament material which is continuously fed into a filament material processing apparatus, when a tangled portion occurs. The present invention relates to a method for preventing a part from being caught in a facility and tightened in a kink shape, thereby preventing disconnection.

2. Description of the Related Art Conventionally, as a method of preventing entanglement and breakage of a wire material of this kind, as shown in FIG. 3, a wire material 3 is fed from a coil-shaped wire material 2 set in a wire material feeding device 1. The entanglement detecting device 4 is configured to continuously feed the entangled portion 3A of the wire material 3 via the entanglement detecting device 4, and the entangled portion 3A is detected by the entanglement detecting device 4. There is a method of preventing the wire 3 from breaking by sending a stop signal to the wire 3 to stop the wire.

[0003]

However, if the entangled portion 3A of the wire 3 is light, the entangled portion 3A is not detected by the entanglement detecting device 4, but is directly It is sent to. As a result, if the entangled portion 3A is caught in the equipment of the wire material processing device 5 and tightened in a kink shape, there is a case where the wire is broken, and if the wire is broken, the wire material processing device 5 stops. Therefore, there is a disadvantage that time is wasted until the reworking of the entangled portion 3A is completed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in FIGS. In the drawing, reference numeral 1 denotes a wire feeder, 2 denotes a coiled wire set in the wire feeder 1, 3 denotes a wire fed from the coiled wire 2, and 4 denotes an entangled wire. Detecting devices 5 and 5 are linear material processing devices, and since these devices have the same configuration as the conventional device shown in FIG. 3, detailed description thereof will be omitted.

Reference numeral 6 denotes a ball installed in front of the wire material processing apparatus 5, which is formed entirely of a synthetic resin in the illustrated embodiment in order to prevent the wire material 3 from being damaged. However, the object of the present invention can be achieved by making at least only the surface layer of a resin. Reference numeral 7 denotes a through hole formed at a position in the diametrical direction passing through the center of the resin ball 6. According to the results of the experiment, the resin ball 6 has an outer diameter of 3 to 2 times the diameter of the linear material 3.
And the inner diameter of the through-hole 7 is the wire material 3.
It is preferable that the diameter is 2 to 10 times the diameter.

Here, the resin ball 6 is supported by the linear material 3 inserted through the through hole 7 and is installed in front of the linear material processing device 5. Therefore, the resin ball 6 is installed in the through hole 7 so as to be rotatable around the wire 3 inserted in the through hole 7.

Then, the wire material processing apparatus 5 is operated,
The wire 3 is fed out from the coiled wire 2 set in the wire feeding device 1 and is continuously sent to the wire processing device 5 via the entanglement detecting device 4. When the entangled portion 3A is generated in the strip material 3, if the entangled portion 3A is large to some extent, it is detected by the entanglement detection device 4, and the detection signal from the entanglement detection device 4 is used. 5 stops.

However, when the entangled portion 3A of the wire 3 is light, the entangled portion 3A is not detected by the entanglement detecting device 4 and is sent to the wire material processing device 5 as it is. However, since the resin ball 6 is provided in front of the wire material processing apparatus 5, the entangled portion 3A comes into contact with the outer peripheral surface 6A which is a spherical surface of the resin ball 6. Become.

The entangled portion 3A is formed on the outer peripheral surface 6 of the resin ball 6.
When the resin ball 6 is rotated around the linear material 3 inserted into the through hole 7 by the external force due to the collision with A, the outer peripheral surface 6A is formed as a spherical surface. Due to the spherical surface and the rotating action, the entangled portion 3A is extended to some extent without being tightened in a kink shape, and is sent out to the wire processing apparatus 5 through the through hole 7.

Therefore, it is possible to reliably prevent the occurrence of an accident in which the tangled portion 3A is tightened in a kink shape and is caught by equipment, and the wire 3 is disconnected. In addition,
In the present invention, by using in combination with the conventional entanglement detecting device 4, it is possible to more reliably prevent the wire 3 from being disconnected.

EXAMPLE In the case where the diameter of the filament material is 10.0 mm, a resin ball having a through hole having a diameter of about 20 mm is set in front of the filament material processing apparatus. The number of disconnections was measured by experiment. The measurement results are as shown in Table 1. The number of disconnections was significantly reduced as compared with the case where no resin ball was set. This indicates that, when the entangled portion occurs, the entangled portion is less likely to be tightened in a kink shape due to the spherical action and the rotating action of the resin ball.

[0014]

As described above, in the method for preventing entanglement and breakage of a filament according to the present invention, the filament is rotatable in a plane orthogonal to the feeding direction in front of the entrance of the filament processing apparatus. Since it is configured to pass through the through hole of the ball, even if a entangled portion occurs in the linear material, the entangled portion is extended to some extent by the spherical surface and rotation of the ball, and passes through the through hole. It is sent out to the wire rod processing device. Therefore, the entangled portion is less likely to be caught and broken by the equipment of the wire material processing apparatus, and
Processing efficiency is improved.

Further, by forming at least the surface portion of the ball from a resin, the entangled portion can be elongated without damaging the linear material. further,
With a configuration in which a through hole is formed at a position in the diameter direction passing through the center of the ball, the ball can freely rotate in any of 360 ° directions with the through hole as a center of rotation. Therefore, even when the entangled portion of the filament material hits any part of the spherical surface of the ball, the entangled portion can be smoothly rotated and stretched, and the wire can be caught by the equipment of the filament material processing device and broken. There are various effects.
