BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for recovering fiber chips generated when an optical fiber cable (hereinafter sometimes referred to as an "optical cable") is cut by an optical fiber cable cutting cutter. It is about.

[0002]

2. Description of the Related Art As represented by the Internet, the modern society is an information society supported by information transmission by high-speed communication. In such an information society,
Communication using an optical fiber cable is excellent in the demand for information, which has a large capacity, and its facilities are expanding.

[0003] An optical cable is a bundle of several to several hundred thin glass fibers of about 0.1 mmφ.
As the development of the communication network progresses, each optical fiber is connected to each communication device to be arranged. For such a connection, a specific optical cable bundled (for example, an optical cable of the main line) and an optical cable connected to a specific communication device (for example, a branch line) Optical cables) must be connected on the way.

In the connection work of an optical cable, if the cut end surface of the optical cable is not perpendicular to the axis, refraction or reflection of light serving as a carrier wave occurs at the connection surface, and a connection failure may occur. It needs to be done precisely.
In order to cut each of the bundled optical cables perpendicularly to the axis thereof, a dedicated optical cable core cutting cutter is used. A wide variety of optical fiber cable cutting cutters are commercially available. Hereinafter, a commercially available optical cable fiber cutting cutter (Furukawa Electric Co., Ltd., optical fiber cutter S321 (trade name)) will be described as an example. The outline will be described.

FIGS. 9 and 10 are manufactured by Furukawa Electric Co., Ltd.
It shows an outline of an optical fiber cutter S321 (trade name). 1 is a cutter body for cutting an optical cable, and 2
Is a cutter blade moving table, and the main body 1 is provided with a lid 3, a cutting button 4, and a lid opening lever 5.
Reference numeral 6 denotes a special holder for accommodating an optical cable for maintaining the axis of the core wire horizontal with respect to the cutter main body 1. Reference numeral 7 denotes a cemented carbide circular cutter blade. Clamps 9 and 10 attached to the lid 3 are a carrier for placing an optical cable core to be cut and providing a horizontal surface, 11 is a pillow fitted with the tip of the cutter blade 7, and 12 is a pillow. The core 13 of the optical cable to be cut is a rotating shaft for opening and closing the lid 3.
The support tables 9 and 10 are arranged on a straight line with the separated portion A interposed therebetween.

The manner in which the core of the optical cable is cut by the optical cable core cutting cutter will be described.

[0007] First, after removing the covering portion of the optical cable to be cut, the core wire 12 is set on the dedicated holder 6 while leaving a margin for cutting, and the dedicated holder 6 is supported by the core wire 12. The tables 9 and 10 are set so as to be horizontal to the cutter body 1 and the axis thereof is perpendicular to the circular cutter blade 7.

Next, the cover 3 is covered from above, and the clamp 8 and the carrier 9 and the clamp 14 and the carrier 10
9 with the core wire 12 interposed therebetween.
Slide in the direction of the arrow shown in. Cutter blade slide 2
Slides the cutter blade 7 so that the core 1
2 is rubbed to make a cut in the core wire 12. Thereafter, when the pillow 11 is lowered by pressing the cutting button 4 from above, the core wire 12 is cut at the location where the cut is made. After cutting, the lid 3 is opened and the dedicated holder 6 is taken out.

[0009]

However, such an optical cable has a single core of 0.125 mmφ (coating outer diameter of 0.25 mmφ or 0.9 mmφ) or a plurality of single cores (4.5 × 8 core). ) Is a bundled tape-shaped core wire, and even if the core portion is cut using the optical cable core cutting cutter, such a core wire made of very thin glass fiber is Since it is extremely thin and transparent, it can be easily stabbed into the body, and if it is stabbed into the body, it is difficult to be detected by magnetic field exploration, radiography, and the like, so that careful handling is required.

[0010] That is, if the core wire stabbed into the skin enters the artery, it may get on the bloodstream and damage the heart and lungs. In addition, since core wire scraps are extremely lightweight,
With breathing, it may enter the respiratory tract via the mouth and nose.

For these reasons, conventionally, when cutting the core of the optical cable in the connection work of the optical cable, the number of the core scraps of the cut optical cable is checked (particularly, the tape including a plurality of cores). Although collection is performed, it is very difficult to collect extremely fine and transparent core dust as described above, and it takes time to clean up after the connection operation is completed. And other issues had arisen.

On the other hand, especially when connecting an optical cable outdoors, it is necessary to temporarily restrict the traffic of a car or the like, so that a quick work is required. It is required to minimize the time required for confirming the number of core debris and recovering work after completion of a typical connection work.

According to the present invention, there is no need to directly touch the wire debris so as to prevent an operator from being injured by the cut fiber debris when cutting the optical fiber by the optical fiber wire cutting cutter. An object of the present invention is to provide a core wire scrap collecting device that can easily collect core wire scraps in a short time.
