【Example】

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. FIG. 1 is a perspective view showing a jacket remover for optical tape fiber according to the present invention. 2, the coating is removed by the optical tape fiber jacket remover according to the present invention. FIG. In these figures, as explained in Fig. 3 above, Components that are the same or equivalent to the above are given the same reference numerals and detailed explanations are omitted. . In these figures, 11 is a cutting blade as a protrusion for setting the coating stripping length. The cutting blade 11 is located opposite to the main body 4a and the pressing part 4b of the coating removal member 4. It is protruded from the side part. Note that this cutting blade 11 has a main body 4a and a pressing part 4b. By holding the tip of the optical tape fiber under pressure with the It is configured to cut the core wire. Moreover, the installation position of this cutting blade 11 is The part that is closer to the tip of the optical tape fiber core than the cutting blade 6, and the cutting blade 6 and are set at predetermined intervals. Between the cutting blade 6 and the cutting blade 11 The distance S is the distance between the optical fiber cutter and the fiber body in the later optical fiber cutting process. The dimensions are longer than those required for cutting. In addition, in Figure 2, 12 13 is the removed coating, and 14 is the fiber body.

[0008] The fixing holder 2 used in this example has a coating removal section along the guide 3. The distance L (total movement amount) that can be separated from the material 4 is the distance between the cutting blade 6 and the cutting blade 11. It is set to be shorter than S. This movement amount setting can be done, for example, by guide 3. This is done by providing a stopper (not shown) on the

Describes the procedure for removing the tip coating of optical tape fiber using a mover. do. First, the optical tape fiber core 12 is sandwiched between the fixing holder 2 in the same manner as before. The tip of the optical tape fiber core 12 protrudes from the fixing holder 2 while being held under pressure. The portion is held under pressure by the coating removing member 4. At this time, the main body 4a and the coating removal member 4 When the pressing part 4b is pinched and operated, a cut is made in the coating by the cutting blade 6. At the same time, the cutting blade 11 cuts the tip of the optical tape fiber core 12 to a predetermined length. Cut off. After that, hold the fixing holder 2 along the guide 3 until the guide 3 stops. It is separated from the coating removal member 4. In this way, as shown in Figure 2, the tip side The coating 13 is pulled out and moved along the fiber body 14, and the fiber The main body 14 is exposed. At this time, the distance S between the cutting blade 6 and the cutting blade 11 is Since the total movement distance of the fixed holder 2 is short, the tip of the fiber body 14 is not inserted into the coating 13. remains. After peeling off the coating 13 in this way, use an optical fiber cutter to The fiber body 14 is cut to have a predetermined protrusion length. In this case, the The other fiber body 14 (fiber waste) is attached to the optical tape while being integrated with the coating 13. The fiber core 12 is then separated.

0010 Therefore, in the optical fiber cable jacket remover according to the present invention, Will the coating 13 remain on the tip of the fiber body 14 when the coating 13 is removed? Therefore, the cut fiber waste can be handled in a state where it is integrated with the coating 13. Become so.

[0011] In addition, in this example, the protrusion for setting the coating stripping length was constituted by the cutting blade 11. Although the example is shown, instead of the cutting blade 11, the tip of the optical tape fiber core 12 is brought into contact. It is also possible to use a plate member for positioning. As shown in this example, If the protrusion for setting the stripping length is configured by the cutting blade 11, long optical tape fibers can be cut. When creating a fused part in the middle of the fiber core, the optical tape fiber core must be removed before the coating is removed. Since there is no need to cut the wire, work efficiency can be increased. Moreover, it is turned off. When the cutting blade 11 is used, the tip of the optical tape fiber core 12 is attached to the coating removal member 4. By holding the coating under pressure, the length of the coating 13 to be removed can always be maintained at a constant value. can.
