Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a core wire supply device among devices for fully automatically connecting optical fibers.

[Conventional technology and problems] For example, something like a pistol magazine,
As shown in FIG. 4, a bullet 10 is placed in a magazine 12, kept pressed upward by a spring 14, and pushed out by a horizontal cylinder 16, or
The structure is such that the upper lid 18 can be removed and exposed upward.

However, optical fibers with a thickness of about 0.25 mm are too thin to use the above-mentioned equipment, and until now there is no automatic feeding equipment.

[Means for Solving the Problems] As shown in FIG. has at least one flat surface, a large number of V-grooves 24 are provided on that surface parallel to each other and at the same pitch p, and is movable by the length p in a direction perpendicular to the V-grooves 24; (3) Although the holding plate 34 cannot be moved, it can be opened and closed with respect to the base plate 20, and when closed, the V
It is in contact with the optical fiber 26 inserted into the groove 24 and prevents the optical fiber 26 from escaping.
The above-mentioned problem is solved by providing it near the front end 35 of the holder.

[Example] In FIG. 1, 20 is a base plate, which is a rectangular plate with a flat surface.

This base plate 20 is movable in the direction of arrow 22.

Although the mechanism for movement is not shown, any known mechanism may be used, such as a plate gear provided below the base plate 20 and driven by a motor.

24 is a V-groove, which is located on the base plate 20 in the direction indicated by the arrow 2.
2, a large number of them are provided parallel to each other at an equal pitch p.

The optical fiber 26 is inserted into the V-groove 24.

Reference numeral 28 denotes a light shielding plate, which is attached, for example, to the lower surface of the base plate 20, and slits 30 are provided at the same intervals as the pitches p.

A positioning sensor 32 is, for example, a transmission type.

The sensor 32 and the slit 30 control the movement mechanism of the base plate 20 and move the base plate 20
can be advanced one pitch p at a time.

34 is a holding plate. This is attached at its rear end to a frame 36 by a hinge 38 and can be opened and closed. However, it will not move.

40 is a sending means. This corresponds to supply position 41 (second
(See figures a to c)
It is for feeding in two directions and includes a pair of rollers (see Japanese Patent Application No. 62-25177).

This delivery means 40 is shown in FIG. 2a as follows.
Set it at the position of the supply device 41.

Further, the position of the front end 35 of the holding plate 34 is at the second c.
In the figure, the position is set midway between the supply position 41 and the discharge position 43, which is one bit p away.

[Function] (1) First, the base plate 20 is set at the rear end as shown in FIG. 2a, the holding plate 34 is opened, and the optical fiber 26 is set in the V-groove 24.

(2) Next, feed the base plate 20 by one pitch p,
The first optical fiber 26a is set in the supply position 41 (FIG. 2b).

Then, the optical fiber 2 is
6a is sent.

(3) When the series of operations for the optical fiber 26a that has been fed out is completed and the optical fiber 26a is to be discharged, the base plate 20 is further fed by one pitch p (FIG. 2c).

Then, the optical fiber 26a moves to the ejection position 43 and comes off the holding plate 34, so that it can be easily ejected.

At the same time, the next optical fiber 26 is set at the supply position 41.

(4) In addition, if the feeding means 40 (supply position 4
1) is provided at a position one pitch p or more rearward from the front end 35 of the holding plate 34. When the state shown in FIG. It turns out that I'm in the hospital and I'm not feeling well.

[Other Embodiments] Since the optical fiber 26 is very thin, in the above example, only the holding plate 34 is placed on it, but if the holding force is to be increased, a weight may be placed on the holding plate 34, or a third As shown in the figure, a second holding plate 44 may be added to utilize the force of a compression spring 46.

[Effects of the Invention] (1) With only one actuator for moving the base plate 20, the optical fiber can be automatically supplied and the optical fiber can be discharged after the work is completed.

(2) During operation, the optical fiber is fixed by the holding plate 34, and when ejecting, the optical fiber can be easily ejected.

(3) Optical fibers can be automatically supplied with a simple configuration.
