Abstract

PROBLEM TO BE SOLVED: To provide a crank-type braiding machine which achieves the high-speed travel of a carrier and low noise by inventing a new braiding machine having a structure without a face plate, by focusing attention on the presence of the face plate causing noise generation and speed reduction in the conventional braiding machine.SOLUTION: Drive shafts connected to respective drive gears are extended upward from the respective drive gears. A plurality of horns which are connected to the respective drive shafts and are rotated are provided in such a state that their peripheral parts are adjacent to each other. A plurality of guide grooves provided on the outer periphery of each horn are in communication with those provided on the outer periphery of an adjacent one of the horns. A first small-diameter gear connected to the middle part of each drive gear meshes with a second small-diameter gear meshing via a relay gear. A carrier shaft rotated by a second relay gear is extended.

Description

  The present invention relates to a blade machine in which wire rods fed from bobbins of a plurality of carriers braid the outer periphery of a core material, and relates to a new type crank blade machine capable of moving a carrier at high speed and reducing noise.

  Conventionally, a blade machine in which a wire such as a steel wire is braided on the outer periphery of a flexible core material such as a tube has a face plate with a center hole through which the core material passes, and surrounds the center hole. In this way, the two grooves are provided with annular track grooves intersecting each other.

  As an example of such a conventional blade machine, referring to Patent Document 1, a disk-shaped face plate includes a first track groove and a second track groove that form an annular shape in the circumferential direction of the face plate. It is formed so as to penetrate in the direction. In such a configuration, the respective track grooves are formed in the circumferential direction of the deck plate while intersecting each other in the shape of an eight, and are provided at the lower portion of each carrier in each of the first track groove and the second track groove. It is set as the structure which guides driving | running | working in the state in which the guidance part which comprises ship shape was pinched | interposed.

  However, in the structure in which the track groove intersecting in an 8-character shape is formed on the deck plate that guides the traveling of the carrier as described above, when the carrier travels, the ship-shaped guide portion becomes an 8-shaped track groove. It will run in a sandwiched state. At that time, frictional resistance is generated when the carrier guiding portion contacts the raceway groove, and at the eight-shaped intersection, the guiding portion hits the corner portion, so that the traveling speed of the carrier decreases or noise occurs. There was a problem that occurred.

  Therefore, when using a blade machine having such a face plate, lubricating oil is supplied in order to reduce the frictional resistance between the raceway groove and the carrier. Not only was it contaminated with oil, but it did not solve the problem of noise and speed reduction.

In the combined state, while being guided by the rotation of the drive gear, it moves into the inside of one guide groove of the adjacent horn so as to move around the flexible core. Each wire is braided on the outer periphery of the flexible core material by feeding the wire wound around the bobbin of the carrier provided on the surface of the carrier to the outer periphery of the flexible core material with a predetermined tension. It is characterized by that.

  A crank type blade machine according to a second aspect of the present invention is the crank type blade machine according to the first aspect, wherein the first crank coupled to the drive shaft and the second crank coupled to the carrier shaft are rotatably engaged with each other. As a result, the carrier shaft is configured to move to one guide groove of an adjacent horn while being guided as the horn rotates while being engaged in one guide groove of each horn. It is characterized by that.

  The above-described crank type blade machine according to the present invention enables the carrier to run without providing a face plate that has been used in the past, so that it has an eight-shaped start formed on the face plate as in the conventional blade machine. There are no grooves, and there is also no boat-shaped guide that travels in the starting groove. For this reason, the elements that caused the noise generation of the conventional blade machine and the decrease in the traveling speed of the carrier are eliminated, and in the alternative carrier traveling structure, the carrier shaft supporting the carrier is guided by the guide groove of the horn. Because of the structure that moves while moving, it is possible to reduce the frictional resistance when the carrier travels, and to realize smooth high-speed traveling of the carrier and reduction of noise.
