FIG. 1 is a front view showing a braider with a mold clamping device of the present invention, FIG. 2 is a side view thereof, FIG. 3 is a front view showing the mold clamping device, FIG. 4 is a side view thereof, and FIG. It is a side view which shows the state which passes.

The overall structure of the blader according to the present invention will be described with reference to FIGS. The blader BR includes a blader body Bb and a mandrel device Bm.
The blader body Bb is arranged along a curved upper plate 12 having a predetermined radius of curvature R and a track formed in the upper plate 12 and disposed in a substantially cylindrical machine base 11 having an opening e and having a horizontal axis. Carrier C, bobbin carrier C traveling
D, a composition position stabilizing guide member G, a cutting device S, and a bobbin support device I for a middle thread or reinforcement. The mandrel device Bm includes a machine base Fm and a mandrel moving device M.

The curved upper plate 12 is attached to a substantially cylindrical machine frame 11c disposed in a substantially cylindrical machine base 11 by a suitable fixing member 13 at a predetermined interval. A well-known track is formed in the upper plate 12 in the circumferential direction. The bobbin carrier C is configured to travel along a track formed on the upper plate 12 by a suitable driving means such as a motor in the driving device D. Further, the yarn Y is unwound from the bobbin placed on the bobbin carrier C, heads toward the composition point P on the mandrel m, and is used for a middle or reinforcing yarn (hereinafter referred to as a middle yarn). Y) is unwound from a bobbin carrier C which is mounted on the side wall 11a of the substantially cylindrical machine base 11 by the reinforcing bobbin support device I and is disposed substantially horizontally, and is guided by the guide roller 14 mounted on the machine base 11. Are guided in a substantially right angle direction toward the composition point P on the mandrel m.

In this blader, as described above, the bobbin carrier C is perforated on the curved upper plate 12 so that a large number of yarns Y are interlaced to form a braid around the mandrel m. If necessary, the yarn y for the middle yarn is wound from the bobbin carrier C disposed substantially horizontally on the side wall 11a of the machine base 11 and unwound from the bobbin carrier C traveling along the track. It is configured to be entangled with Y to form a braid.

The composition position stabilizing guide member G is mounted on the machine base 1.
A first annular composition position stabilizing guide member 15 attached to a frame 15a extending in a substantially horizontal direction from the first intermediate frame 11b;
The second composition position stabilizing guide member 16, which is also substantially annular, is attached to the front end of a frame 16a erected on a floor member Fr arranged at a predetermined interval from the fifth member 5. The composition point P is disposed between the first composition position stability guide member 15 and the second composition position stability guide member 16.

The first composition position stabilizing guide member 15 and the second composition position stabilizing guide member 16 arranged at a predetermined interval travel while meandering along a track formed on the upper plate 12. This guides the yarn Y swaying as the bobbin carrier C moves in the lateral direction, and regulates the swaying to maintain the composition point P at a substantially constant position.

By maintaining the composition point P at a substantially constant position, a stable composition can be realized without the yarn Y to be composed being irregularly entangled near the composition point P.
Therefore, the shape of the braid thus composed can be produced uniformly and stably. Further, in the present braider BR, a braid that presses the braid immediately after or immediately before the composition from the outer periphery to the outside of the first composition position stabilizing guide member 15 and the outside of the second composition position stabilizing guide member 16 near the composition point P. A fastening device 50 is additionally provided to increase the density and reduce the thickness of the braid formed on the outer periphery of the mandrel m.

The mandrel device Bm is arranged on the front surface (right side in FIG. 2) of the blader main body Bb. Above the machine base Fm, the upper plate 12 arranged in the blader main body Bb is substantially provided. A horizontal moving frame 21 that can move horizontally toward the center is arranged. Below the horizontal moving frame 21, a motor 22 is attached to the machine base Fm, and the motor 22 drives the horizontal moving frame 21 horizontally. A mandrel supporting and moving member 23 is fixed to an end of the horizontal moving frame 21 on the side of the blader body Bb, and the mandrel m is fixed by the mandrel supporting and moving member 23.
, And the mandrel m moves horizontally in accordance with the horizontal driving of the horizontal moving frame 21.

The cutting device S is arranged at the lower end of a frame 31 suspended from the front of the blader body Bb.
The cutter device 33 is rotationally driven by the motor 32,
The cutter device 33 is configured to cut a large number of yarns Y connected to the braid whose composition is completed on the outer periphery of the mandrel m.

The process of forming a braid around the mandrel m by the blader Bb configured as described above will be described. First, the horizontal movement frame 21 of the mandrel device Bm is horizontally moved to position one end of the mandrel m supported by the mandrel support moving member 23, for example, the right end in FIG. In this state, the driving device D is driven to move the bobbin carrier C along the track to start the composition, and the horizontal moving frame 2
2 is gradually moved rightward in FIG. 2 to perform composition from the right end of the mandrel m to the left. Then, the composition is performed up to the left end of the mandrel m, and when the composition of the mandrel m is completed, the driving device D is stopped to stop the traveling of the bobbin carrier C.

Next, the horizontal moving frame 21 is largely moved rightward so that the left end of the mandrel m is positioned closer to the machine base Fm than the cutter device 33 of the cutting device S. From this state, the cutter device 33 is rotationally driven by the motor 32,
The cutter device 33 is brought into contact with a number of yarns Y connected to the bundled braid to cut the yarns Y. In the present braider BR, once the composition is performed from the right end to the left end of the mandrel m as described above, the mandrel m is moved in the opposite direction, and the composition is performed again from the left end to the right end. It is also possible to apply the composition to multiple layers.

Next, for example, a braid immediately adjacent to the composition point P, which is attached to the outside of the first composition position stabilizing guide member 16 and the outside of the second composition position stabilizing guide member 16, is pressed from the outer periphery. The mold clamping device 50 will be described. As shown in FIG. 3 to FIG.
0, the base plate 51 formed in a ring shape is
Are rotatably supported by a plurality of guide rollers 63 rotatably attached to a frame 59 of the mold clamping device 50. Outer peripheral portion 51a of the base plate 51
Is formed in a gear shape and meshes with a gear 61 that is rotationally driven by a motor 62 fixed to a frame 59,
The base plate 51 is configured to be rotatable by a motor 62.

A plurality of roller members 52 are attached to the base plate 51 via an arm 53 on the same circumference. One end of the arm 53 is rotatable about a pivot 55. The roller member 52 is attached to the plate 51 and the other end of the arm 53 is rotatably attached.
A spring 57 is interposed between the arm 53 and the base plate 51, and the spring 57
Is urged inward of the base plate 51.

An adjusting plate 54 formed in a ring shape is attached to the base plate 51, and the adjusting plate 54 is configured to be rotatable around the center of the base plate 51. A pin 56 is fixedly mounted on the adjusting plate 54 so as to slidably fit into the elongated hole 53a formed in the arm 53, and the pin 56 and the adjusting plate 54 are integrally rotatable. I have. Roller member 52 rotatable about a rotation fulcrum 55
The position of the arm 53 in the radial direction is regulated by a pin 56 fitted into the long hole 53 a of the arm 53.

When the adjusting plate 54 is rotated to the right with respect to the base plate 51, the pin 56
3a slides in the direction of the roller member 52, and the spring 57
The roller member 52 is turned outward in the radial direction against the urging force. Conversely, when the adjustment plate 54 is rotated to the left with respect to the base plate 51, the pin 56 slides in the long hole 53 a of the arm 53 toward the rotation fulcrum 55, and the roller member 52 is biased by the spring 57. Rotate inward in the radial direction. That is, the position of the roller member 52 in the radial direction can be adjusted by rotating the adjusting plate 54 left and right with respect to the base plate 51.

By attaching the thus configured mold clamping device 50 to the outside of the first composition position stabilizing guide member 15 and the second composition position stabilizing guide member 16, the braid is formed as shown in FIG. Immediately after or immediately before being composed, the mandrel m passes through the mold clamping device 50, and the mandrel m
The roller member 52 is located on the outer periphery of the roller member 52. In this case, the radial position of the roller member 52 of the mold clamping device 50 is adjusted so as to press against the braid immediately after being formed on the mandrel m or immediately before being formed. Pressed and crushed. Since the base plate 51 of the mold clamping device 50 is driven to rotate by the motor 62 while the mandrel m passes through the inside of the mold clamping device 50, the roller member 52 revolves around the outer peripheral portion of the mandrel m and rotates by itself. While pressing the braid.

As described above, the roller member 52 is pressed against the outer peripheral portion of the mandrel m by the biasing force and position adjustment of the spring 57 to press the braid immediately after being formed on the mandrel m or immediately before being formed. Thereby, it is possible to squeeze the yarn Y or the fiber bundle which is formed in a substantially circular cross section and which constitutes the braid, so that the mold can be clamped so as to be flattened and spread. Thereby, it is possible to increase the density of the assembled braid and to form the braid thinly.

Further, since the roller member 52 continuously presses the braid while rotating the outer peripheral portion of the mandrel m, it is possible to uniformly clamp the whole braid. Further, since the member that presses the braid is the roller member 52 that is configured to be rotatable, the resistance at the time of pressing can be reduced, the pressing can be performed smoothly, and the uniformity of the mold clamping can be improved. Further, since the roller member 52 is configured to be able to move its radial position, the roller member 52 crushes the thread or fiber bundle constituting the braid in accordance with the diameter of various mandrels m, that is, the diameter of the braid. The mold can be clamped. Although a plurality of roller members 52 are provided in the present embodiment, even when only one roller member 52 is provided, the mold can be clamped in the same manner as described above.

Next, another embodiment will be described. In the above-described configuration, the position of the roller member 52 may be automatically adjusted only by the urging force of the spring 57 with the adjustment plate 54 being in a free state when the mold clamping device 50 is operated. Further, in the above-described embodiment, the combination of the elongated hole 53 a formed in the arm 53, the pin 56, and the adjustment plate 54 is configured so that the positions of all the roller members 52 in the radial direction can be simultaneously adjusted. The roller members 52 may be configured to be individually position-adjustable and position-fixable. In this case, the motor 62 may not be used, and the roller member 52 may be changed in direction and rotated in the moving direction of the mandrel m. With this configuration, the present invention can be applied to a mandrel having a cross section other than a circular shape.

[0026]

According to the present invention, in a braider with a mold clamping device, the following effects can be obtained by employing the above-described configuration. First, as set forth in claim 1, a mold clamping device for pressing the braid immediately after the composition or immediately before the composition from the outer peripheral portion is provided in the vicinity of the composition point of the braider, so that the cross-section is formed into a substantially circular shape, thereby forming the braid. The mold can be clamped to squash the fiber bundle and flatten out. Thereby, it is possible to increase the density of the assembled braid and to form the braid thinly.

[0027] Further, as set forth in claim 2, the mold clamping device includes a roller member that rotatably moves an outer peripheral portion of the braid.
Since the braid is pressed by the roller member, it is possible to smoothly press the braid with less resistance at the time of pressing, and to improve the uniformity of the mold clamping.

Further, since the roller member is configured to be movable in the radial direction of the braid, the yarns constituting the braid correspond to various diameters of the mandrel, that is, the diameters of the braid. The fiber bundle can be crushed and clamped.
