Description

Braiding machine

The present invention relates to a braiding machine for composing braids.

Conventionally, in this seed braiding machine, as shown in Patent Document 1 below, a plurality of horn disks that rotate in opposite directions are arranged circumferentially, and a plurality of carriers including a thread bobbin and a buffer are provided. Passing between horn discs. In addition, the braiding machine body is provided with a substantially horizontal plate. In this plate, annular grooves are formed along the outer periphery of each horn disk, and the two types of menopause are repeated by alternately communicating the inner and outer circumferences of the grooves. A road is formed. In addition, a guide portion that is guided in each closed path protrudes from the lower end of each carrier. Then, when a pair of carriers that are guided and moved in each closed path by the guide portion are transferred between the horn disks, the yarn is crossed, and the crossed yarn is wound up to form a braid.

Further, in the braiding machine, each closed path can be switched to two types of closed paths by left and right divided by the switching means. By this switching means, the carrier is moved along two types of closed paths on the left and right divided into left and right, while the two types of closed paths on the left and right are communicated with each other, and the carrier is moved along each long closed path. Is moving.

US6907810 B2

However, in the above-described conventional one, each closed path is formed on a single plate, so that the posture of each carrier moving along each closed path becomes unstable. For this reason, rattling or twisting is likely to occur between the closed path and the guiding portion when each carrier moves on each closed path, and this tendency becomes particularly prominent when the carrier is moved at high speed.

The present invention has been made in view of the above points, and the object of the present invention is to stabilize the posture of each carrier during movement and suppress rattling or twisting between the closed path and the guiding portion. It is another object of the present invention to provide a braiding machine that can move a carrier at high speed.

In order to achieve the above object, the present invention comprises a plurality of carriers for feeding out a yarn and a plurality of horn disks for rotating the respective carriers, and each of the carriers is delivered by passing the carriers between the horn disks. Assume a braiding machine that crosses yarns from each carrier and winds the crossed yarns to form a braid. The braiding machine main body is provided with a plurality of plates in the vertical direction, and each plate is provided with an annular through groove that penetrates along the outer peripheral portion of each horn disk. Two types of closed paths are formed, which are communicated to repeat the inner and outer turns of each through groove alternately. Furthermore, each carrier is provided with a plurality of guiding portions that are guided in each closed path for each plate.

Further, each carrier is moved along each closed path of each plate for each closed path, while one closed path to the other closed path at the intersection of the closed paths of the plates that intersect each other. It moves so that it may move over the said each closed path | route, crossing. Then, the intersection of each closed path of at least one of the plates intersects with the restriction position for restricting the movement of each carrier from the one closed path to the other closed path at the intersection. It is preferable to provide a switching means for switching to an allowable position that allows movement of each carrier from one closed path to the other closed path.

Further, it is preferable that the switching means is provided for each intersection of the plates.

Further, it is preferable that the switching means of each plate is switched between a restriction position and an allowable position in synchronization with each other via a link mechanism.

Further, the switching means includes a first advancing / retreating member that advances and retreats so as to partition between one closed path and the other closed path at the intersection, and the one closed path to the other at the intersection. A second advancing / retreating member that advances and retreats so as to guide the guiding portion to the closed path. The first advancing / retracting member is advanced and the second advancing / retreating member is retracted when the switching means is switched to the restricted position, while the first advancing / retracting member is retracted and the first advancing / retreating member is retracted when switching to the allowable position. It is preferable to advance the two-way member.

Further, it is preferable that the first advance / retreat member and the second advance / retreat member are moved forward and backward in a substantially horizontal direction at the intersection.

Furthermore, it is preferable that the horn disks are arranged between the plates adjacent to each other in the vertical direction among the plurality of plates.

According to the braiding machine according to the present invention, a plurality of closed paths are respectively formed in a plurality of plates in the vertical direction, and a plurality of guide portions that are guided in each closed path for each plate are provided in the carrier. The distance between the upper and lower guide portions that are guided with respect to each closed path of each plate becomes long, and the posture during movement of each carrier in each closed path is stabilized. As a result, rattling or twisting between each closed path and the guiding portion during movement of each carrier can be suppressed, and each carrier can be moved at high speed.

In addition, a switching means for restricting or allowing movement of each carrier from one closed path intersecting at the intersecting portion to the other closed path is provided at the intersection of each closed path of at least one of the plates. Thus, the movement of each carrier from one closed path to the other closed path at the intersection of each closed path can be easily restricted or permitted by the switching means.

In addition, by providing a switching means for each crossing portion of each plate, each carrier moves from one closed path to the other closed path at each crossing point of each closed path, and is guided by a plurality of guiding parts. Can be smoothly regulated or allowed.

In addition, each plate switching means is synchronized with each other via the link mechanism to switch between the restricting position and the allowable position, so that it is not necessary to switch each plate switching means with each individual drive source synchronized. By switching the driving source, the plate switching means can be switched while being easily synchronized.

Further, when the switching means is switched to the restriction position, the first advance / retreat member is advanced and the second advance / retreat member is retracted to partition between one closed path and the other closed path, while at the time of switching to the allowable position. By retracting the first advancing / retracting member and advancing the second advancing / retracting member to guide the guiding portion from one closed path to the other closed path, the first and second advancing / retreating members that advance when switching the switching means The guidance part can be guided to move each carrier at each crossing part smoothly while stabilizing the posture.

Further, the first advancing / retracting member and the second advancing / retreating member are moved back and forth in the substantially horizontal direction at the intersection, so that a space in the advancing / retreating direction of each advancing / retreating member can be secured in the substantially horizontal direction, and the switching means is moved in the vertical direction. A compact layout is possible.

Further, by disposing the horn disks between the vertically adjacent plates, the distance between the vertically adjacent plates is separated by the horn disks, and accordingly, the distance between the upper and lower guide portions is long. As a result, the posture of each carrier when moving is further stabilized. As a result, rattling or twisting during the movement of each carrier in each closed path can be effectively suppressed, and high-speed movement of each carrier can be enabled at a high level.

paths

37 and 38 are combined with the composition of the single braid A at the restricted position or the permitted position. Prior to the execution of the composition of the braid B, regulation is performed so as to regulate the communication between the through grooves 31 of the

cross paths

37 and 38 and the through grooves 31 of the left and right

closed paths
