DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotating distribution plate provided with a twisting mechanism.

[0002]

2. Description of the Related Art As shown in FIG. 3 (a), an optical fiber core (not shown) is dropped into an SZ groove 10A of an SZ grooved filament 10, or such a cable is further used as a core. When an optical fiber core is twisted in multiple layers thereon, or a metal material wire 20A is further placed on the core 20 of the metal material cable as shown in FIG.
In the case of twisting and twisting, a device for imparting a twisting rotation to a wire to be twisted on an optical fiber core or a core is required.

[0003]

However, in a collective device in which various element devices are mounted in a congested manner,
Further, the addition of the twisting device leads to an increase in the size of the machine, and a great disadvantage in terms of cost as well as an increase in space. For this reason, there has been a demand for the emergence of a device which is integrated with the rotating distribution plate or in which the rotating distribution plate itself has a built-in twisting mechanism.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the invention according to the first aspect of the present invention is supported by a base so as to be rotatable and has an outer peripheral portion. A ring-shaped dividing plate main body provided with a gear portion, a core guide cylinder rotatably provided at a central position inside the dividing plate main body and provided with a gear portion on the outer periphery, and also provided at peripheral equally divided positions It has a plurality of twisting cylinders each having a gear portion on the outer periphery, and has a twisting mechanism in which the gear portion of the core guide tube and each gear portion of the twisting tube mesh with each other with a desired gear ratio. It is a rotating dividing plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. A vertically extending flat base 1 is rotatably provided with a drive gear 2 that is driven forward / reversely by a drive motor 4 at a predetermined appropriate period so that the intermediate gear 3 meshes with the drive gear 2. Is provided.

Similarly, a base plate 5 is rotatably provided on the base 1 so as to mesh the gear 51 with the intermediate gear 3. As described, the core guide cylinder 7 and the twisted cylinder 8A are attached.

That is, a pair of side plates 6A and 6B having an outer diameter corresponding to the inner diameter of the ring of the dividing plate main body 5 are prepared, and the center and the periphery are equally divided in the circumference (in the example shown, 5 equally divided). A round hole for attachment is formed in (1), and a core guide tube 7 is disposed in the center hole.

The core guide cylinder 7 has a generally hollow cylindrical shape,
The central position in the axial direction is a large-diameter gear portion 72, and the hollow portion serves as a guide hole 71 on which the SZ-grooved wire body 10 shown in FIG. 3 or the metal cable core 20 runs.

[0009] Twisted cylinders 8A, 8B, ..., 8E, which are the same parts as each other, are arranged at a plurality of equally-divided portions on the periphery. The twisted cylinder 8A or the like generally has a hollow cylindrical shape, and a large-diameter gear portion 82 meshes with the gear portion 72 of the core guide cylinder 7 near the center in the axial direction. The core wire or the metal material wire passes. These wires are wires to be twisted by the apparatus of the present invention. The ratio of the number of teeth between the gear portion 72 and the gear portion 82 is determined separately according to a desired twisting ratio.

The component indicated by reference numeral 83 provided at the entrance of each of the twisted cylinders 8A is a branching head used in the case of a tape core, and extends in a direction perpendicular to the axial direction of the twisted cylinder. A plurality of branch pins 84 that are attached across
The tape core wire is separated by one or two sheets and passed therethrough, and then combined into one, so that the rotation of the passing tape core wire relative to the twisting cylinder is suppressed to ensure reliable twisting rotation. To give.

Next, the operation of the apparatus of the present invention will be described. S
The Z-grooved wire body 10 or the core 20 of the metal material wire is guided to run in the guide hole 71 of the core guide cylinder 7. The optical fiber cores to be dropped or the metallic material wires to be twisted are the five twisted cylinders 8A, 8B,
.., 8E.

In the case where the optical fiber is dropped into the SZ-groove wire, the drive gear 2 is driven by the drive motor 4 in accordance with the SZ inversion pitch of the SZ groove of the SZ-groove wire. Accordingly, the main body 5 is rotated forward and backward.

In this case, the gear portion 72 of the core guide cylinder 7 functions as a sun gear, the gear portion 82 of each twisted cylinder functions as a planetary gear, and since the intermediate gear 3 is provided, each of the twisted cylinders 8A, 8A,
8B and the like rotate in the opposite direction to the branch plate main body 5, respectively, and can give a desired twist to the optical fiber core wire running therethrough.

Since the gear portion 72 of the core guide cylinder 7 located at the center and the gear portion 82 of each of the twisted cylinders at the periphery are completely symmetrical with each other, the gear portion 72 may be fixed. , Or in either direction at a desired angular velocity. In this way, a desired rate of twist can be imparted to the optical fiber.

[0015]

According to the first aspect of the present invention, it is not necessary to provide a dedicated twisting device in addition to the rotating distribution plate as a part of the collecting device, and the entire collecting device can be made compact. This has the advantage of facilitating the design of the collective device.
