Abstract

PURPOSE:To eliminate a harmful effect caused by a cutting waste, by installing a cutting waste container communicating with a through-hole, to a holding member on which the through-hole for inserting the tip part of an optical fiber has been pierced. CONSTITUTION:When cutting an optical fiber 13, its coating is removed by a suitable length from its tip, and its coating removed part 14 is inserted into a through-hole 5 of a holding member 4. Subsequently, the tip side of the coating removed part 14 is pushed and stopped on a plate-shaped member 1 through a holding member (not shown in the figure), the coating removed part 14 is flawed by a cutter (not shown in the figure) of a cutting apparatus, and thereafter, when the plate-shaped member 11 is curved, the coating removed part 14 is ruptured from a part of its flaw. Thereafter, the pushed-up state by the holding member is released, a press pump 9 of a suction mechanism 8 is contracted temporarily, and thereafter, when the pump 9 of a suction mechanism 8 is contracted temporarily, and thereafter, when the pump 9 is restored, its suction force reaches the through-hole 5 of the holding member 4, and the through-hole 5 and the inside of a cutting waste container 11 become a negative pressure, therefore, a cutting waste such as a broken piece, etc. of the coating removed part 14 is sucked into the cutting waste container 11 and collected.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a debris removal device suitable for collecting cut debris from optical fibers.

``Prior art 1: When connecting optical fibers, the ends of the optical fibers are cut as required.

As such optical fiber cutting machines, hand grip type for manual cutting, portable type for mechanized or automated cutting, etc. have been provided and put into practical use.

- When using any of the cutting machines described above, the optical fiber is stripped from its end, and then the stripped end of the optical fiber is placed in position on the cutting machine and cut. Ru.

As is well known, the outer diameter of an optical fiber is approximately 1 mm even if it is coated with a secondary coating, and the outer diameter of an optical fiber from which the coating is removed is approximately 100 p-re.

``Problem to be solved by the invention J: Cutting debris after cutting an optical fiber is harmful and dangerous.

For example, if the cutting debris gets stuck inside the cutting machine, it will interfere with the next cutting operation, and if touched carelessly, it will pierce your fingers.

° Therefore, the cutting waste should be collected deftly and
Although it is desirable to properly dispose of the fiber, it is difficult to collect the cut waste (bare fiber) because it has a minute diameter as described above and is extremely short.

Therefore, under the present circumstances, cutting debris generated by optical fiber cutting tends not to be sufficiently collected, or the cutting debris is often left scattered at the work site.

In view of the above-mentioned problems, the present invention aims to provide a device that can easily collect cut debris from optical fibers.

Means for Solving Problem 1 The optical fiber cutting waste removal device according to the present invention includes a holding member having a through hole for inserting the tip of the optical fiber, and a hole communicating with the through hole. It is characterized in that a cutting waste container is attached, and piping for a suction mechanism is connected to these through holes and any arbitrary part of the cutting waste container.

Effect 1 In the device of the present invention, when cutting an optical fiber, the tip of the optical fiber is inserted into the through hole of the holding member, and after cutting the optical fiber, the suction mechanism is activated.

When the suction mechanism is activated, a negative pressure is created in the through hole of the holding member or the cut waste container, and the cut ends of the optical fiber, that is, the cut waste present in the through hole are sucked into and collected in the cut waste container.

Thus, when using the apparatus of the present invention, cut debris of the optical fiber can be easily collected.

Embodiment J An embodiment of the apparatus of the present invention will be described below with reference to the drawings.

In Figures 1 and 2, 1 indicates a leaf spring 2 and the leaf spring 2.
It is a plate-like member consisting of a sheet rubber 3 attached to the surface of the sheet rubber.

4 is a holding member made of metal or synthetic resin, and this holding member 4 is provided with a through hole 5 for inserting an optical fiber, and an insertion port 6 is formed at one end of the through hole 5. A suction lower is provided to intersect with the through hole 5.

8 is a suction mechanism, and this suction mechanism 8 consists of a squeeze pump 9 and a pipe 10 connected to the squeeze pump 8.

The squeezing pump 8 of the suction mechanism 8 is mutually connected to the suction lower of the through hole 5 via piping 10.

Reference numeral 11 denotes a cut waste container made of synthetic resin, and a mouth portion 12 of the cut waste container 11 is removably fitted into the insertion opening 6 of the through hole 5.

In the figure, 13 is a coated optical fiber, and 14 is a coating removal portion on the tip side of the optical fiber.

Next, an example of collection of cut debris caused by cutting the optical fiber 13 will be described.

When cutting the optical fiber 13, the coating is removed from the tip of the optical fiber 13 by an appropriate length, and the coating removed part 14 is inserted into the through hole 5 of the holding member 4. The coated portion of the fiber 13 is supported via a support member on the end side (not shown) of the plate-like member 1, and the coat-removed portion 14 comes to follow the surface of the plate-like member 1 in this set state.

Next, the coating removing portion 14 is
When the distal end side of the optical fiber 13 is pressed onto the plate-like member 1 and the coat-removed portion 14 is scratched with a blade of a cutting device (not shown), and the plate-like member 1 is bent, the coat-removed portion 14 of the optical fiber 13 It breaks at the damaged part.

After the cutting, the pressing state by the pressing member is released.

Next, when the squeeze pump 8 of the suction mechanism 8 is once contracted and then restored, the suction force is applied to the through hole 5 of the holding member 4 via the piping 10, thereby causing the through hole 5 to Since the inside of the cutting waste container 11 becomes a negative pressure, the cut ends of the coating removal section 14 located in the through hole 5, that is, the cutting waste, are sucked into the cutting waste container 11 and collected.

By repeating the above-mentioned cutting waste collection, the cutting waste container 1
When the interior of the cutting waste container 1 is filled with cutting waste, a new cutting waste container 11 is set in the holding member 4, and the cutting waste container 11 containing cutting waste is sealed and discarded.

In addition, as the suction mechanism 8 mentioned above, one mainly based on the compression pump 9 was used, but the pump may be a centrifugal type,
Various types are used, such as reciprocating type and rotary type.

The pump piping 10 may be connected to a suction port provided at a suitable location on the cutting waste container 11, and in this case, the suction lower of the holding member 4 is omitted.

On the other hand, the device of the present invention can be used in combination with various types of ready-made optical fiber cutting equipment, such as hand grip type, mechanized or automated portable type, and in this case, the holding member 4 serves as a holding part for the tip of the optical fiber. Available.

In addition, when the device of the present invention is combined with an automatic optical fiber cutting machine, the cutting machine is equipped with an electric circuit for sequence control, and by activating the suction mechanism 8 at a predetermined time, it is possible to automatically remove scraps after cutting the optical fiber. You can also take it.

4. Effects of the Invention As explained above, when using the device of the present invention, it is possible to easily collect the cutting debris caused by cutting the optical fiber, and therefore, when cutting the optical fiber as necessary, it is possible to easily collect the cutting debris caused by the cutting debris when cutting the optical fiber. Bad effects can be wiped out.
