Description

  The present invention relates to a blade machine according to a braided braiding apparatus for braiding a plurality of wires on the outer periphery of a core material such as a tube.

  In general, there are a vertical type and a horizontal type of blade machine for braiding a wire material such as a wire around the outer periphery of a core material such as a tube. Of these, the horizontal type requires a large space for installing the apparatus, so that the vertical type blade machine is economical in terms of installation space. Further, in such a vertical blade machine, a braiding device called a braided type or a braided type is known, but the braided type braided device is currently used widely.

  By the way, this braided braiding apparatus is provided with a metal surface board having a center hole for allowing a flexible core material such as a tube to pass therethrough, and has an 8-shaped continuous annular shape so as to surround the center hole. A plurality of carriers that run on the upper surface of the face plate along the running grooves are formed, and a wire rod is fed upward from each bobbin provided on each carrier, whereby the above-described core material What is comprised so that the outer periphery of this may be braided is known.

As a conventional example using such a face plate, referring to a braiding device listed in Patent Document 1, as shown in FIG. 7, a disk-shaped deck plate (corresponding to the above-mentioned “face plate”) includes a deck. A first raceway groove 60a and a second raceway groove 60b that form an annular shape in the circumferential direction of the plate 60 are formed so as to penetrate the deck plate 60 in the plate thickness direction, and each raceway groove 60a, 60b has a corrugated shape. And extending in the circumferential direction of the deck plate 60 while intersecting each other in the shape of an eight. The traveling of the carrier is guided in a state in which the guide portion 61 having a ship shape provided at the lower portion of the carrier is sandwiched between the first raceway groove 60a and the second raceway groove 60b.
Japanese Patent Laid-Open No. 11-247057

  However, in the configuration in which the 8-shaped raceway groove of the deck plate 60 that guides the traveling of the carrier is formed as described above, when the carrier travels, the track-shaped groove 60a, 60b in which the ship-shaped guide portion 61 forms an 8-shaped form. The friction between both sides of the raceway groove is caused by running in the state of being sandwiched between the two, especially at the intersection of the eight-shaped, there is a disadvantage that the traveling speed of the carrier is lowered by hitting the corner. .

  The present invention has been made to eliminate such inconvenience, and a face plate for guiding the traveling of a carrier used in a blade machine that braids a wire around the outer periphery of a core (this face plate is referred to as the present invention). An object of the present invention is to provide a blade machine improved so that the traveling speed of the carrier does not decrease.

  In order to achieve the above object, a blade machine according to claim 1 of the present invention is a blade for braiding the outer periphery of a core material by feeding a wire from each bobbin provided on a plurality of carriers according to the travel of the carrier. In the machine, the carrier has a guide dowel that protrudes downward from the center of a slide base provided at a lower portion thereof, and is spaced above a base plate fixed to an upper portion of a casing of the blade machine. A receiving plate is provided, and a plurality of horn gears are provided on the upper side of the receiving plate with the rotation centers arranged on the same circumference, and a plurality of cuts formed at equal intervals on the outer periphery of each horn gear. The notch groove is configured to be able to rotate in a connected state for each adjacent horn gear, and a continuous arc-shaped side portion in which an arc shape is continuously formed for each horn gear is provided on the inner periphery of the receiving plate. When the carrier guide dowel is engaged with the notch groove of the horn gear and the carrier slide base is mounted on the horn gear, the carrier guide dowel is a continuous arc of the receiving plate. Guided along the inside of the shaped side.

  A blade machine according to a second aspect of the present invention is the blade machine according to the first aspect, wherein a lower base is provided at a lower end portion of the guide dowel for the carrier, and a lower end of the continuous arc-shaped side portion at the lower base. The vehicle is characterized in that it travels in a state where the part is sandwiched.

  In the present invention configured as described above, the member forming the carrier shape of the carrier travels in a state of being sandwiched between the traveling grooves having an 8-shaped annular shape as in the prior art. A continuous arc-shaped side portion formed by continuously forming a circular arc shape for guiding the carrier traveling around the horn gear is provided around the circumference, and the carrier guiding dowel is engaged with the notch groove of the horn gear. Because this guiding dowel is guided along the inside of the continuous arcuate side of the receiving plate, it is difficult for frictional resistance to occur, and the traveling speed of the carrier is affected even at the corner of the continuous arcuate side. Therefore, it is possible to realize stable running at a constant speed.

  In addition, the receiving plate used in the blade machine of the present invention is not a face plate having a complete circular shape, but has a shape having a continuous arc-shaped side portion on the inner periphery, and the inside thereof is a cavity. In addition, the carrier slide base does not travel on the upper surface of the receiving plate, but travels along the upper surface of the horn gear.

The boat-shaped member provided on the base surface of the carrier 20 travels along the traveling groove while being guided. However, in the present invention, the traveling groove having an 8-shaped annular shape is eliminated. Accordingly, the ship member of the carrier 20 is also abolished, and a simple dowel 28 having a circular bar shape is formed.

  That is, the receiving plate 23 of the present invention is a shape of a conventional face plate having an 8-shaped annular shape, leaving the outer shape of the 8-shaped annular shape, so that the receiving plate 23 is shown in FIG. It will have the shape of a hatched part. As shown in this figure, the continuous arc-shaped side portion 50 provided on the inner periphery of the receiving plate 23 is provided for each horn gear 29 (27 in FIG. 3 indicates a through hole of the connecting shaft 26 of the horn gear 29).

Travels while being guided along the inner periphery of the continuous arc-shaped side portion 50 of the receiving plate 23 and is transferred to the notch groove 37 side of the adjacent horn gear 29, whereby each carrier 20. The wire rod W supplied from the bobbin 21 is sent to the outer periphery of the core member 17 and braided.

  When the carrier 20 is traveling, in this embodiment, the guide dowel 28 of the carrier 20 is subjected to frictional resistance only on the side contacting the continuous arcuate side portion 50, but is not contacted on the opposite side. Because the vehicle travels without being restricted, the carrier-shaped member of the carrier is sandwiched between the eight-shaped travel grooves as in the prior art, and friction resistance hardly occurs. Even in this part, the traveling speed of the carrier 20 is not affected, and stable traveling at a constant speed can be realized.
