Abstract

The present invention is to provide a braider rotor, which minimizes noise and vibration spread toward the front of a faceplate, generated during an operation of a braider, and can increase the braiding efficiency by increasing a rotation speed of a rotor. The braider rotor of the present invention comprises a rotor having a carrier transport notch formed at a position where the circumference of a circular plate is divided in equal, and a horn gear installed at a horn gear shaft installed in an orthogonal direction to the faceplate and rotatably supporting the rotor, and transferring a driving force to allow adjacent rotors to be rotated in a direction opposite to each other. The horn gear is separated from the rotor to install the rotor in a front portion of the horn gear shaft positioned at a front side of the faceplate, and the horn gear is installed to be distributed at a rear end portion of the horn gear shaft passing through the faceplate.

Description

{BRANIDING MACHINE ROTOR}

The present invention relates to a knock-out rotor capable of minimizing noise and vibration generated during operation of a knitting machine for braiding a steel wire such as stainless steel to a rubber or synthetic resin hose, .

Generally, in a knitting machine, a rotor is a carrier transferring means for transferring a loaded carrier carrying a bobbin wound around a face plate while rotating on a face plate so as to traverse the braided orbit.

Conventional knurl rotors are horn-gear integrated type, as disclosed in the Utility Model No. 20-2010-0002157 and the No. 20-2010-0009460, No. 20-2015-0000277, which are known from the prior art documents. The horn gear is a spur gear engaged with the horn gear of the adjacent rotor to rotate the rotor.

The horn gear integrated rotor is installed on the front side of the face plate as a horn gear shaft. The rotor is installed in an even number for stable braiding and for shaping of the braided structure.

In the case of braiding, the contact noise between the teeth caused by the horn gear meshing, the fricative between the foot and lace that occurs when the foot of the carrier slides on the race of the rotor, the crossing of the race to the carrier from the leading rotor to the trailing rotor Almost all of these noises are reflected by the face plate and propagate toward the direction of advance of the knitted fabric, that is, toward the front side of the face plate.

Noise pollution is large even when one knitting machine is in operation. If there is a large number of knitting machines in a single knitting workshop, the noise is so large that it is difficult to cope and has a great influence on the knitting operation. On the other hand, the weight of the rotor is biased by the weight of the horn gear shaft which supports the horn gear integrated rotor, and vibration is generated. The vibration is also a cause of the noise, and the bearing replacement period is short because it causes uneven wear of the bearing. The greater the unevenness of the bearing, the slower the rotation of the rotor.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a knockout rotor capable of minimizing noise and vibration generated during the operation of a knitting machine and spreading toward the front side of a face plate,

In order to achieve the above object, the present invention provides a rotor having a rotor having a notch for conveying a carrier in an equally divided circumferential area of a disk, and a rotor disposed in a direction orthogonal to the face plate and provided on a horn gear shaft rotatably supporting the rotor, The rotor is separated from the rotor by a horn gear which is disposed in the front half of the horn gear shaft located at the front side of the face plate and at the rear end of the horn gear shaft penetrating the face plate, This can be accomplished with a rotary knife rotor in which gears are distributed and installed.

During braiding, the noise generated by the horn gear spreads to the back of the faceplate, and the noise generated by the rotor and carrier spreads to the front of the faceplate.

According to the dispersion arrangement of the rotor and horn gear, the load applied to the horn gear shaft is dispersed, the uneven wear of the bearing is reduced, and the vibration is also reduced.

According to the present invention, the noise generated from the horn gear during braiding is dispersed to the front and back of the face plate due to the activity of the rotor and the carrier, so that the noise pollution is reduced and the worker's fatigue is less.

The rotor and horn gear are distributed to the front and rear of the shaft of the horn gear to suppress the uneven wear of the bearings due to the concentration of the load and the vibration to be significantly reduced and the weight of the rotor to the front half and the rear half of the horn gear shaft can be balanced to some extent. It can smoothly and quickly rotate and increase the braiding efficiency.

BRIEF DESCRIPTION OF THE DRAWINGS Fig.

In the present invention, a horn gear (3) having a shaft hole (4) pierced at the center of the shaft hole (2) is separated from a rotor (1) in which a shaft hole (2) is perforated. As the horn gear 3 is disengaged, the rotor is lightened.

The horn gear shaft 5 of the present invention is divided into a first half portion 6 and a second half portion 7 and the first half portion 6 is for installing a rotor and the second half portion 7 is for installing a horn gear. The intermediate portion 8 positioned at the boundary between the first half portion 6 and the second half portion 7 is a part that is fitted to the shaft hole of the face plate and is supported.

Although the ratio of the lengths of the front half portion 6 and the rear half portion 7 is not strictly defined, it is helpful to equalize the load applied to the horn gear shaft 5 to reduce vibration and rotational noise during operation due to weight It is preferable to design the first half portion 6 and the second half portion 7 to have the same length.

When the rotor 1 is provided at the front end of the horn gear shaft 5 and the horn gear 3 is provided at the rear end of the horn gear shaft 5, the same features as those of the assembly of Fig. Reference numeral 9 denotes a key for preventing the horn gear from turning, 10 is a key plate, and 11 is a key plate deviation prevention bolt.

3 and 4, the horn gear shaft 5 is fitted to the shaft hole of the face plate 12 provided with the bearings at both ends thereof from the rear end of the horn gear shaft 5, Tighten the lock nut (13, 14) to the rear half of the horn gear shaft (5) to stabilize the shaft mounting state.

Next, the shaft hole 4 of the horn gear 3 is inserted into the rear end of the horn gear shaft 5, the key 9 is inserted to prevent the endless rotation, and the key plate 10 is provided at the rear end of the horn gear shaft 5, The rotor 1, the horn gear 3, and the horn gear shaft 5 are finished by fastening the bolt 11 with the bolts 11 and fixing the key plate.

Reference numeral 15 denotes a race, and reference numeral 16 denotes a foot.

The present invention is characterized in that the rotor 3 is provided on the front side of the face plate 12 and the horn gear 3 is provided on the rear side of the face plate so that the front and rear constituent members are separated into front and rear parts of the face plate.

When the rotor 1 and the horn gear 3 alone are placed, the weight of the both sides including the horn shaft 5 is substantially balanced with respect to the face plate 12. Thus, the rotor 1 and the horn gear 3 are not weighted to one side during the knitting operation, so that the vibration can be minimized, so that the rotation can be quietly performed and the rotation is also facilitated.

The noise generated from the horn gear 3 is dissipated toward the back surface of the face plate 12 and the noise toward the rotor 1 spreads toward the front of the face plate 12. [ Compared with the case where the noise on the rotor 1 side and the noise on the horn gear 3 are spread apart, the noise pollution during the braiding is reduced to half, compared with the case where the both side noises are spread together, so that the braiding can be performed in a still quiet atmosphere.
