[0015]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
[0016]
Note that the same components as those in the conventional example are denoted by the same reference numerals and description thereof is omitted.
[0017]
FIG. 1 is a partially enlarged perspective view of a yarn braid abnormality detecting device attached to a yarn braid hose 4 embodying the present invention. The yarn braid hose 4 is circumferentially directed toward the supply side of the reinforcing yarn 3. A cylindrical detection member 11 provided with a locking member 12 made up of a plurality of needle-like projections at a predetermined interval is slidably and detachably fitted.
[0018]
The cylindrical detection member 11 divided into two in the longitudinal direction is connected to be openable and closable via a connection member 13, and a plate-like connection member 14 is suspended vertically below the detection member 11. The limit switch 6 is attached so as to contact the detector 7.
[0019]
One end of an elastic member 16 composed of a rubber string member (such as a rubber band) is attached to the plate-like connecting member 14 via a return member 17 in a direction opposite to the hose conveying direction (arrow X direction). The other end of the elastic member 16 is hooked on a hook 18 fixed on the braiding machine 2 side.
[0020]
Member 17 return from the above, or twisted elastic member 16 to set the time of the detection member 11, without dislodged, but the detection member 11 is always provided a fixed posture for one holding and elastic members 16 The limit switch 6 is mounted so that the distance L between the detector 7 and the plate-like connecting member 14 can be maintained at 20 to 30 mm.
[0021]
That is, even if the detection member 11 moves to the limit switch 6 side due to friction with the yarn braiding hose 4, the detector 7 of the limit switch 6 and the plate-like connecting member 14 come into contact with each other before the limit switch 6 operates. It is configured to be pulled back to the braiding machine 2 side by the elastic force of the member 16. The yarn braid abnormality detecting device is installed in a plurality of units corresponding to the number of yarn braid layers when the hose body 1 has a plurality of layers of yarn braiding.
[0022]
Next, the operation of the yarn braid abnormality detection device will be described.
[0023]
First, as a detection method when a yarn braiding abnormality such as yarn breakage or looseness of the reinforcing yarn 3 occurs when the hose body 1 is braided, a yarn break end portion or a slack portion includes a plurality of detection members 11. It catches on the locking member 12 which consists of any needle-like protrusion.
[0024]
Then, with the movement of the braided hose 4, the detection member 11 when also moved in the transport direction, the detector 7 of the plate-like connecting member 14 is a limit switch 6 provided on the detecting member 11 abuts, with the limit switch 6 is activated An abnormal braiding of the reinforcing yarn 3 is automatically detected and the braiding machine 2 is stopped.
[0025]
Next, as a method of preventing malfunction of the limit switch 6 other than yarn braiding abnormality such as yarn breakage or slack, for example, a hose body 1 is connected to a tube connecting portion (joint portion), a knot portion of the reinforcing yarn 3, When there is a connection portion of insulation and is thicker (larger) than the general outer diameter portion of the hose body 1, the hose body 1 is formed on the inner surface portion of the detection member 11 when the hose body 1 passes the detection member 11. In some cases, the detection member 11 is dragged and moved by the friction.
[0026]
In this case, since the detecting member 11 has a force to pull back to the braiding machine 2 side by the elastic force of the elastic member 16, the detecting member 11 moves slightly due to friction with the bulging portion of the hose body 1. Since the elastic force that the elastic member 16 pulls back becomes larger than the frictional force until the plate-like connecting member 14 provided on the member 11 contacts the detector 7 of the limit switch 6, the plate-like connecting member 14 provided on the detecting member 11. Is pulled back to the original position without contacting the detector 7 of the limit switch 6.
[0027]
As a result, the limit switch 6 does not operate, and therefore the braiding operation is continuously performed without stopping the braiding machine 2. As a result, malfunction of the braiding machine 2 can be prevented, work efficiency can be improved, and work such as operator restart can be further reduced.
[0028]
Further, as in the conventional case, when abnormal braiding such as yarn breakage or loosening of yarn occurs during yarn braiding, it can be reliably detected to prevent outflow of defective products of the braided hose 4.
[0029]
【The invention's effect】
In the present invention, the elastic member 16 that urges the elastic force in the direction opposite to the hose conveyance direction is connected to the plate-like connecting member 14 of the cylindrical detection member 11 as described above, and the elastic force of the elastic member 16 is applied to the yarn. The size of the braided hose 4 is set so as to pull back the detection member 11 toward the braiding machine 2 against the frictional force generated when the portion other than the yarn braid abnormality of the braided hose 4 slides on the inside of the detection member 11. It is possible to effectively prevent malfunction of the braiding machine other than the portion and the slack portion of the yarn, improve the work efficiency, and reduce the operator 's work.
