Description

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

  Conventionally, a blade machine that braids a wire material such as a steel wire around the outer periphery of a flexible core material such as a tube has a face plate with a central hole through which the core material passes, and surrounds the central hole. Are provided with annular track grooves in which two grooves intersect each other. A pair of carriers travels along this annular track groove while being guided by a rotating horn gear, and the wire fed from the bobbin of each carrier is braided on the outer periphery of the core material passing through the center hole of the face plate. Has been.

  Referring to Patent Document 1 as a conventional example of a blade machine configured as described above, 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 in a state of penetrating in the plate thickness direction. Each track groove has a corrugated shape and is formed in the circumferential direction of the deck plate while intersecting each other in the shape of an eight. Each of the first track groove and the second track groove has a pair of carriers. Travel guidance is performed with a guide portion having a ship shape provided at the lower part sandwiched therebetween.

  Each carrier is provided with a bobbin shaft and a wire drawing hole, and the wire rod from the bobbin rotatably fitted to the bobbin shaft is pulled out from the drawing hole and inserted through the center hole of the deck plate. It is set as the structure which winds and braids by mutually crossing the outer peripheral surface of the flexible elongate body which moves relatively in the axial direction of a deck board spirally.

  However, in the structure in which the track groove intersecting in the shape of figure 8 is formed on the deck plate that guides the traveling of the carrier as described above, when the carrier travels, the track in which the ship-shaped guide portion forms an 8-shaped shape. When traveling in a state where it is sandwiched between the grooves, frictional resistance is generated by contacting both sides of the raceway groove, and particularly at the 8-shaped intersection, the guiding portion hits the corner portion, so that the traveling speed of the carrier is reduced. There is a problem in that the carrier level is lowered, the carrier is loose, and noise is generated.

  Further, in the blade machine as described above, a new system type blade machine such as Patent Document 2 has been devised by the present applicant in order to enable the carrier to travel at high speed. In such a conventional blade machine, it is possible to obtain a result that the carrier's standing posture in a stable state without tilting is beneficial for the high-speed traveling and low-noise traveling of the carrier by subsequent research. did it. However, according to the structure of the conventional blade machine, when the wire rod is fed from the bobbin of the traveling carrier and braided on the outer periphery of the core material, the carrier is always pulled toward the center of the face plate through which the flexible core material passes. The standing posture of the carrier becomes unstable and wear resistance is generated on the face plate and the like, which hinders the speeding up of the carrier and causes noise.

Japanese Patent Laid-Open No. 11-247057 Japanese Patent No. 4325735

  The present invention has been made in view of the above circumstances, and realizes high-speed traveling and low-noise traveling by smoothly running each carrier traveling in the raceway groove of the face board in a stable standing posture without inclination. Another object of the present invention is to provide a high-speed new system type blade machine capable of reducing the generation of noise caused by contact or collision while each carrier is running.

  In order to achieve the above object, a new system type blade machine according to claim 1 of the present invention is characterized in that two grooves are formed on the peripheral surface of a face plate in which a central hole through which a flexible core material is passed. A plurality of annular raceway grooves are formed by continuously intersecting in an annular shape, and each of the horn gears provided at the center of each annular raceway groove is driven to rotate, and a plurality of A boss provided on the carrier is engaged with the guide claws of the carrier, and a boat-shaped portion protruding and formed at the lower part of each carrier is guided along the annular raceway groove of the face plate. In a high-speed blade machine in which the carriers run in opposite directions, each carrier is fitted as a lower structure of the carrier body between a boss upper hook and a boss lower hook provided below the boss gear guide claws. And a boat-shaped part is formed on the lower surface of the lowermost anchor that is fixed to the lower surface of the lower boss. The outer side of each horn gear is surrounded by a horn outer panel provided above the face plate. In addition, the inside of each horn gear is composed of a horn inner plate that has a central hole through which a flexible core material passes, and the upper surface of these horn outer plates and the upper surface of the horn inner plate are the same height as the upper surface of the horn gear. In addition, the carrier travels in a state where the lower surface of the upper boss is uniformly supported.

  Further, the new system type blade machine according to claim 2 of the present invention is characterized in that, in claim 1, the lowermost hook of the carrier, the boat-shaped portion, and the horn gear are formed of nylon resin.

  The above-mentioned new system type blade machine of the present invention is configured such that, as the lower structure of the carrier body, the outer side of each horn gear is surrounded by a horn outer plate provided above the face plate, and the inner side of each horn gear is constituted by a horn inner plate. The carrier travels in a state where the upper surface of the outer horn plate and the upper surface of the horn inner plate are flush with the upper surface of the horn gear and the lower surface of the boss upper hook is evenly supported. That is, when the carrier boss is on the outer horn side with the horn gear guiding claw fitted, the lower surface of the carrier boss upper hook is at an equal height on the upper surface of the horn outer plate and the upper surface of the horn gear. Drive in a supported state. In addition, when the carrier boss is on the horn inner panel side with the horn gear guiding claw fitted, the lower surface of the carrier boss upper hakama is at an equal height on the upper surface of the horn inner panel and the upper surface of the horn gear. Drive in a supported state. For this reason, the carrier can travel on the upper surface of the horn outer plate and the upper surface of the horn inner plate in a stable standing posture without tilting, reducing the frictional resistance during the traveling of the carrier, smooth running of the carrier at high speed and noise. Can be reduced.

  In addition, as the lower structure of the carrier body, the lowermost part of the carrier has a structure in which a boat-shaped part provided in the lowermost hakama travels along the annular track groove of the face plate. This is useful for maintaining the carrier in a stable standing position without tilting, and can contribute to stable running of the carrier and reduction of noise.

  Furthermore, in the new system type blade machine of the present invention, when the carrier travels, the bottom part of the carrier, the boat-shaped part and the horn gear are made of nylon resin which is not used at all in the conventional blade machine. The material on one side of the place where wear contact or collision occurs is made of nylon resin. Since this nylon resin has wear resistance and is excellent in quietness at the time of contact or collision, it is possible to realize low noise when contact or collision occurs as the carrier travels. In addition, since the nylon resin has self-lubricating properties and a small coefficient of contact friction, it can contribute to stable running and high speed running of the carrier.
