[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, when inserting a plurality of optical fiber ribbons into a slot rod having a plurality of slots formed in a spiral shape on the outer peripheral surface, fixes a plurality of optical fiber cables by aligning and laminating them. With regard to the stacking auxiliary jig, in particular, anyone can easily stack multiple optical fiber ribbons and easily insert multiple optical fiber ribbons into the slots at once without the need for labor and labor. The present invention relates to an optical fiber tape core wire stacking auxiliary jig that can be used.

2. Description of the Related Art An optical fiber is provided with a primary coating, a secondary coating and the like to improve mechanical characteristics and easiness of handling as an optical fiber core wire. Then, in the case of forming a cable, the optical fiber ribbon coated with a UV-curable resin or the like and arranged in a plurality and protected by an acrylate resin is housed in a slot rod having a plurality of grooves on the outer peripheral surface, It aims to improve mechanical properties, especially high reliability against lateral pressure. The optical fiber ribbon core wire 3 configured in this way is
As shown in FIG. 11, inside the slot 2 of the slot rod 1 in which the slot 2 is formed in a spiral shape in one direction, for example,
A laminated optical fiber cable 4 is formed by accommodating and accommodating a plurality of optical fiber ribbons 3 each having four optical fibers.

[0004]

However, when the optical fiber ribbons are inserted one by one into the slot 2, the back tension is caused by the twist of the slot 2 which is carved while rotating in the longitudinal direction of the slot 2. When the optical fiber ribbon core wire 3 in the state of being hung on is released, the optical fiber tape core wire 3 rotates inside the core wire stacking jig 5. Therefore, in order to prevent this, one worker inserts the optical fiber ribbon 3 and the other worker inserts the next optical fiber ribbon 3 by two workers. Since the optical fiber tape core wire 3 must be held for a while, the workability is extremely poor, and as the number of slots 2 for storing the optical fiber tape core wire 3 increases, the work of inserting the optical fiber tape core wire 3 is performed. The time will also increase significantly.

It is an object of the present invention that anyone can easily insert end portions of an optical fiber ribbon into an aligned stack so that one slot can be inserted into a stacking jig all at once without requiring any skill. It is about trying to

An alignment groove 46 is formed which is cut in the vertical direction through which the optical fiber ribbons 3 are inserted in a straight line. Groove 4 of this aligned stacking portion 41
The width of 6 is the tape width of the optical fiber ribbon 3 (1.1
The width is a little larger than (mm) ( for example, 1.2 mm). The pre-stage guide section 44 has a function of sequentially stacking and inserting a plurality of optical fiber tape core wires 3 and aligning and stacking the optical fiber tapes, and the pre-stage guide section 45 includes a plurality of optical fiber tapes aligned and stacked in the pre-stage guide section 44. It has a function of holding the core wire 3 so as not to collapse the laminated state.

Next, the operation of the present embodiment will be described. First, the optical fiber ribbons fed from a plurality of supply bobbins (corresponding to the number of optical fiber ribbons to be stacked) (not shown) are aligned and run via pulleys 49 as shown in FIG. The first optical fiber ribbon 3 of the optical fiber ribbons 3A to 3E
A (for example, the optical fiber tape core wire wound on the left end in FIG. 10) is inserted into the alignment groove 46 of the alignment laminating section 41, and the tip of the optical fiber tape core wire 3A is a cylindrical body of the fixing section 42. Then, the vicinity of the tip of the wound optical fiber ribbon 3A is fixed to the fixing portion 42 with the adhesive tape 48.
