Description

  The present invention relates to a high-speed blade machine in which a face board for guiding the running of a plurality of carriers is installed, and a wire or a thread fed from a bobbin provided on each carrier braids the outer periphery of a core.

  A blade machine for braiding a wire material such as a steel wire or a thread material on the outer periphery of a flexible core material such as a tube is provided with a metal surface board having a central hole through which the core material passes, and surrounds the central hole. In this way, the two grooves are provided with an annular track in which the grooves intersect with each other, and a pair of carriers travel along the annular track while being guided by a rotating horn gear, and the wire or thread material fed from the bobbin of each carrier is a surface. The outer periphery of the core material passing through the center hole of the board is configured to be braided.

  In such a braiding machine, in order for each carrier to smoothly travel along the annular track of the face plate, a certain clearance is provided between the groove of the annular track and each carrier. For this reason, when the traveling speed of the carrier is increased, there is a problem that the carrier rattles, noise increases, and the carrier receives a large impact.

  Referring to Patent Document 1 as a prior art made to cope with such a problem, a “blader carrier driving device” described in this document includes a track surface including two intersecting groove-shaped annular tracks, A large number of horn gears, which are rotatably arranged on the back side of the raceway surface and have a plurality of drive grooves on the surface facing the raceway surface, are guided by the raceway grooves, protrude to the back side of the raceway surface, and are guided by the drive grooves. A plurality of carriers that cross and travel in opposite directions along each of the tracks by rotation of the horn gear through a guide pin, and pressing means that presses the carriers against one side wall of the track groove during travel. To do.

  According to this Patent Document 1, the pressing means for pressing the carrier against one side wall has a configuration in which a spring is disposed in the drive groove formed in each horn gear, and the guide pin of the carrier enters the drive groove of the horn gear. In this case, the guide pin is pressed against one of the side walls by urging it outward with a spring, thereby preventing the carrier from rattling and suppressing the generation of noise.

The major difference between the configuration of Patent Document 1 and the configuration of the present invention will be described. The present invention has a structure including a horn gear for running the carrier on the upper side of the face board, and is provided on the carrier. The two circular dowels travel while rotating along an annular track provided on the face plate, whereas the configuration of Patent Document 1 has a track surface (corresponding to the “face plate” of the present invention). Since the horn gear is provided on the lower side, the long insertion portion of the carrier is likely to be rattled along the annular track provided on the track surface.
JP-A-11-200208

  By the way, the conventional blade machine generally has a vertical type and a horizontal type. The vertical type is a structure in which the face plate is provided horizontally and the core material is braided by passing through the center hole of the face plate in the vertical direction, whereas the horizontal type is provided with the face plate vertically. It has a structure in which the core material is braided by passing through the center hole of the face plate in the lateral direction. Although this horizontal type requires a large space for installing the apparatus, it does not require a high installation space like the vertical type, and the overall height of the apparatus is low, which is advantageous in terms of workability.

  However, in such a horizontal blade machine, since the face plate for running the carrier is installed in the vertical direction, the carrier running along the groove-shaped annular track formed on the face plate is due to its own weight. The vehicle travels in a state where it receives a moment load in a vertically downward direction, causing frictional resistance with respect to the annular track, generating a large noise and lowering the traveling speed of the carrier.

  The present invention has been made in order to eliminate such inconveniences, and is a blade machine that braids a wire on the outer periphery of a core material, and a face plate that guides the traveling of a plurality of carriers is installed horizontally. Even in the case where the face plate is installed vertically, the carrier can smoothly travel along the groove-shaped annular track formed in the periphery of the face plate, and the running speed can be increased. An object of the present invention is to provide a high-speed blade machine with low noise.

  In order to achieve the above object, in the high speed blade machine according to claim 1 of the present invention, two intersecting groove-like annular tracks are continuously formed on the periphery of the face plate provided on the frame. In a high-speed blade machine that braids the outer periphery of the core material by feeding the wire from each bobbin provided on a plurality of carriers that run along each annular track, the surface plate can be rotated for each annular track. The provided horn gear is provided on the upper side of the face plate, and a plurality of guide claws are formed on the periphery of the horn gear, and the carrier is a guide pin that engages with the guide claws of the horn gear, and an upper base that sandwiches the guide pin And a lower base and two guide dowels projecting at spaced positions on the lower surface of the lower base, and the guide pins of each carrier are engaged with the guide claws of the rotating horn gear, and the two guide dowels Characterized in that as interlaced travels in the opposite direction along the annular track surface plate.

  The high-speed blade machine according to claim 2 of the present invention is the high-speed blade machine according to claim 1, wherein each of the two guide dowels provided at spaced positions on the lower surface of the lower base of each carrier has a circular diameter in cross section. , Characterized in that it is rotatably provided with respect to the lower base.

  Since the high-speed blade machine of the present invention is configured as described above, as each horn gear provided on the upper side of the face plate rotates, the carrier 2 engaged with one of the guide claws with a guide pin is used. The guide dowels travel along their tracks while being guided along the circular activation. Since each guide dowel has a circular diameter and is configured to be rotatable, when the outer periphery of each guide dowel contacts the side in the groove of the annular track, each guide dowel rotates while rotating Travel along the track.

  Therefore, since the two guide dowels of each carrier run in the predetermined direction in the groove of the annular track while rotating even when hitting the side part in the groove of the annular track, the face plate is installed horizontally. Even if the face plate is installed vertically, the carrier can run smoothly, the carrier traveling speed can be increased, and the carrier guide dowel contacts the side of the groove of the annular track In this case, it is difficult to generate impact noise and friction noise, and it is possible to operate with low noise.
