Description

  The present invention relates to an optical connector cleaning tool for cleaning a joining end surface of an optical connector with a flexible tape-like cleaning body such as a cloth that is continuous in one direction and has a certain width.

  As is well known, if dirt or foreign matter adheres to the joint end face when the optical connector is butt-connected, the joint end face may cause damage at the time of attachment / detachment or increase in transmission loss. Need to be cleaned.

Conventionally, an optical connector cleaning tool has been used to clean the joint end face of an optical connector by contacting the joint end face with a cleaning body made of a flexible continuous material continuous in one direction, such as a string, to wipe off dirt and the like. ing.
As this type of optical connector cleaning tool, at the tip portion (head portion), a part of the cleaning body made of a continuous material is exposed, and the exposed cleaning body is fed and moved in the continuous direction while moving the optical connector. A system is known in which the head portion is rotated about an axis perpendicular to the joint end surface at the same time as contacting (pressing) the joint end surface (see, for example, Patent Document 1).

  In an optical connector cleaning tool employing such a method, a cleaning reel made of a flexible continuous material that is continuous in one direction, such as a string, is fed to the tool tip portion, and a cleaning body from the tool tip portion. And a take-up reel that takes up and winds up, and a rotation mechanism that rotates the head portion.

  Here, the cleaning body that is continuous in one direction is roughly classified into a string-like one having a substantially circular cross section and a tape-like one having a remarkably large width with respect to the thickness. If these string-shaped cleaning bodies and tape-shaped cleaning bodies are compared, as described below, the latter tape-shaped one is more advantageous in terms of the cleaning effect of the joint surface of the optical connector. From the viewpoint of miniaturization of the cleaning tool, the former string-like one is more advantageous, and therefore, conventionally, a string-like cleaning body has been usually used.

  That is, in the case of a string-like cleaning body, the contact area of the cleaning body with respect to the joining surface of the optical connector is small, so even if the head portion is rotated, the pressing force to the joining surface is insufficient or the pressing direction If the pressing force becomes uneven and the pressing force becomes non-uniform, a wiping residue is generated on a part of the joint surface, for example, the peripheral portion, and a situation in which sufficient cleaning cannot be performed easily occurs. On the other hand, when a tape-shaped cleaning body is used, the contact area of the cleaning body with respect to the joint surface of the optical connector is large, so that there is little possibility that unwiping will occur. Therefore, it is desirable to use a tape-shaped cleaning body from the viewpoint of cleaning ability.

  On the other hand, if the winding state when winding the string-like or tape-like cleaning body with the take-up reel in the cleaning tool is described with reference to FIGS. Generally, a large-diameter flange portion 48B, 49B is provided at both ends of a cylindrical portion 47B having a small-diameter cylindrical shape, and the cleaning body 2 is wound around the cylindrical portion 47B. And when winding the string-shaped cleaning body 2, as shown to (a) of FIG. 25, the cleaning body 2 is continuously wound by the fixed position on the outer peripheral surface of the trunk | drum 47B (fixed position). Are usually rolled up one after another, and are usually distributed to some extent in the axial direction of the body 47B. On the other hand, in the case of a tape-shaped cleaning body, as shown in FIG. 25 (b), the cleaning body 2 is unwound around a part of the body portion 37B of the take-up reel 31 and is wound at a substantially constant position. Usually it is rolled up one after another. Therefore, when winding the cleaning body of the same length, if the cleaning body is a string-like and a tape-like case, in the case of a string-like cleaning body, the winding diameter of the cleaning body on the trunk Therefore, the diameter of the take-up reel 31 (the diameters of the flange portions 48B and 49B on both ends of the body portion) D does not need to be so large, whereas in the case of a tape-shaped cleaning body, the winding The diameter is much larger than in the case of the string-like cleaning body, and therefore, the winding reel 31 must have a diameter D that is much larger than that in the case of using the string-like cleaning body. Become. Specifically, for example, assuming a disposable cleaning tool that does not replace the cleaning body stored in the tool and storing a cleaning body of a length that can be cleaned about 500 times with one product, It can be wound with a take-up reel having a diameter D of 12.5 mm and a height (length in the axial direction of the body 47A) of about 7.7 mm, but a tape-shaped cleaning body (for example, the tape width is 2 mm) ) Requires a take-up reel having a diameter D of 40 mm or more and a height H of 2 mm or more.

  As described above, when a tape-shaped cleaning body is used, a take-up reel having a large diameter must be used, which becomes a bottleneck in downsizing the entire cleaning tool, and in terms of the cleaning effect, Although it is superior to the shape-like cleaning body, the actual situation is that its application to actual products has not progressed so much.

Here, when a tape-shaped cleaning body is used, if the tape-shaped cleaning body is overlapped and wound at a certain position, the height H of the take-up reel 31 is smaller than when a string-shaped cleaning body is used. As can be seen from the above example, the amount of decrease in the height H when the cleaning body is changed from a string-like one to a tape-like one is only a few millimeters. Therefore, the increase in the diameter of the take-up reel is much smaller than the increase in the diameter D reaching several tens of mm, and therefore, the increase in the diameter of the take-up reel has become a bottleneck for downsizing the entire tool.
If the number of possible cleanings for one product is sacrificed, it is possible to reduce the size even if a tape-shaped cleaning body is used. However, if that is done, the product value of the product is impaired. Not suitable for products.

International Publication No. 2008/108278

The problem of unwiping of the connector joint end face can also be eliminated or reduced. However, when a tape-shaped cleaning body is used, there is a problem in terms of miniaturization of the tool, and therefore the use of the tape-shaped cleaning body has not progressed.

  The present invention has been made in view of the circumstances as described above, and uses a tape-shaped cleaning body that is advantageous in terms of cleaning effect, but does not increase the diameter of the take-up reel, and does not increase the diameter of the take-up reel.

A plate 42B is formed. Further, the front end plate 46 is formed with a recess 46a through which the extended cylinder 21 is inserted.
With such a configuration, the cylinder base accommodating portion 36 restricts the backward movement of the cylinder base 15 by the restriction plates 42A and 42B and restricts the forward movement by the front end plate 46.

  The urging means accommodating portion 37 is a space between the other side plate 44 </ b> B and the partition plate 43 and accommodates the urging means 40. On the other hand, on the rear surface of the front end plate 46, a holding projection 39 that is inserted into the front end portion of the urging means 40 in the urging means accommodating portion 37 and positions the urging means 40 is formed to protrude rearward (FIG. 3). reference).

It is determined to be closer to the rear than the portion 36 and the biasing means accommodating portion 37.
In the illustrated example, the supply reel support shaft 32 is positioned behind the take-up reel support shaft 33 so that the supply roll 30 is positioned behind the traverse mechanism 120 (the rotation member 126 and the guide member 122) and the take-up reel 31. It has been established. Further, the take-up reel support shaft 33 is defined behind the rotary member support shaft 136 and the intermediate gear support shaft 132 so that the take-up reel 31 is positioned behind the traverse mechanism 120 (the rotary member 126 and the guide member 122). It has been.

  The board 41 is formed with extension plates 45A and 45B extending perpendicularly to the radial direction of the reels 30 and 31, and the ends of the extension plates 45A and 45B project toward the reels 30 and 31, respectively. Locking claws 45Aa and 45Ba are formed. Each of the extending plates 45A and 45B can be elastically bent and deformed, and each of the locking claws 45Aa and 45Ba can move in a direction toward and away from the reels 30 and 31.

A plurality of locking recesses (not shown) arranged in the circumferential direction are formed on the outer surfaces of the first flange plates 48A and 48B, and the locking claws 45Aa and 45Ba of the extension plates 45A and 45B are formed. Is engaged with the locking recess to prevent the reels 30 and 31 from rotating in the reverse direction. A plurality of locking projections (not shown) arranged in the circumferential direction are formed on the outer surfaces of the second flange plates 49A and 49B. The reels 30 and 31 are mounted on the support frame 35 by inserting support shafts 32 and 33 (see FIG. 9) through the body portions 47A and 47B.

Further, the first gear 38 is disposed on the outer surface side of the second flange plate 49B of the take-up reel 31, and the second gear is disposed on the outer surface side of the first flange plate 48B of the take-up reel 31. 130 is fixed.
As shown in FIG. 3, the first gear 38 includes a disk-shaped substrate 89 and a gear portion 88 formed on one surface of the substrate 89. On the other surface of the substrate 89, a locking projection (not shown) that is locked to a locking projection (not shown) of the take-up reel 31 is formed. The gear portion 88 has a tooth portion 88 a that meshes with the receiving tooth portion 56 a of the gear receiving portion 56 of the drive body 13. Here, the first gear 38 is disposed so as to overlap the second flange plate 49B of the take-up reel 31, and the locking projection (not shown) of the substrate 89 is locked to the locking projection (not shown) of the second flange plate 49B. The take-up reel 31 also rotates as the first gear 38 rotates. On the other hand, when the first gear 38 rotates in the direction opposite to the winding direction, the locking projection 87a is not locked to the locking projection (not shown).

  As shown in FIG. 3, the urging means 40 urges the container 11 that has been relatively moved forward to urge the support frame 35 backward and includes a spring member such as a coil spring. Are preferably used. In that case, a reaction force can be applied to the front end plate 46 to urge the pressing portion 57 of the driving body 13 backward.

  As shown in FIGS. 5 and 8, the extension portion 20 includes a cylinder base portion 15, an extension cylinder body 21 provided on the distal end side of the cylinder base portion 15, and a head member inserted through the extension cylinder body 21. 23. The cylinder base 15 includes a holding frame portion 97 that can accommodate the rotating cylinder portion 82 of the rotating shaft 52, and a cylindrical connecting tube portion 96 that extends forward from the front end of the holding frame portion 97. Here, the holding frame portion 97 is formed in a cylindrical shape having a rectangular cross section, and the side plate 99a, which is one of the four side plates 99 constituting the holding frame portion 97, has an insertion protrusion of the driving body 13 along the front-rear direction. A slit 100 into which the portion 54 is inserted is formed.

  As shown in FIG. 5, the extending cylinder 21 includes a cylindrical large-diameter portion 21b and a small-diameter portion 21c extending forward from the front end thereof. An insertion port portion 21d through which the tip extension portion 28 of the head member 23 can be inserted and retracted is formed at the tip of the small diameter portion 21c. On the other hand, a fitting claw 96 a that fits into the locking opening 21 a formed in the large-diameter portion 21 b of the extending cylinder 21 is formed on the outer surface of the connecting cylinder portion 96.

  Here, in the feeding mechanism 3, the traveling position of the tape-like cleaning body 2 that has passed through the head member 23 is reciprocated in a direction parallel to the rotation axis 31 a of the take-up reel 31 at a position before reaching the take-up reel 31. The traverse mechanism 120 for causing the above will be described in more detail with reference to FIGS.

  The traverse mechanism 120 includes a guide member 122 as shown in FIG. 14, a rotation member 126 as shown in FIG. 15 as the motion conversion mechanism, and the rotation prevention member 138 described above. Among these, the guide member 122 is formed as a long plate-like plate as a whole, and is arranged so that the thickness direction thereof is parallel to the rotation axis of the take-up reel 31. The guide member 122 is formed with a through guide portion 124 penetrating in a direction orthogonal to the thickness direction (that is, a direction orthogonal to the rotation axis of the take-up reel 31), and the length direction of the guide member 122 A concave groove portion 122A having a U-shaped cross-section, into which the rotation preventing member 138 is inserted so as to be relatively slidable, is formed along the thickness direction on one end side, and on the other end side in the length direction. A through hole 122C having a substantially circular cross section through which the cylindrical portion 126B of the rotating member 126 passes is formed along the thickness direction, and the rotating member cylindrical portion 126B is formed in a part of the inside of the through hole 122C. A protrusion-like engagement portion 122D is formed which is inserted into a continuous groove-like engagement guide portion 126D formed on the outer peripheral surface 126C.

  The through guide portion 124 of the guide member 122 has a minimum width in the direction parallel to the rotation axis of the take-up reel 31 (and hence the linear reciprocating direction of the guide member 122) in the cross-sectional shape of the inner space. For example, the cross-sectional shape is rectangular or elliptical (rectangular in the illustrated example) so that the minimum interval in the direction perpendicular to the width is smaller than the tape width W. Yes. Further, both end portions in the penetration direction (near the open end) of the inner surface of the penetration guide portion 124 are formed so that their inner surfaces expand toward the outside in a smooth taper shape.

  On the other hand, the rotation preventing member 138 has a rail shape as a whole, and is arranged such that the rail length direction is along the direction parallel to the rotation axis of the take-up reel 31, and the rotation preventing member 138 is The guide member 122 has a convex blocking surface 138A corresponding to the concave groove 122A having a U-shaped cross section. Then, the convex blocking surface 138A of the rotation blocking member 138 is inserted into the concave groove 122A of the guide member 122 so as to be relatively slidable, and the guide member 138 in the plane perpendicular to the rotation axis of the take-up reel 31 is inserted. At the same time as the rotation is blocked, linear movement of the guide member 122 in a direction parallel to the rotation axis of the take-up reel 31 is allowed or guided.

On the other hand, as shown in FIG. 15, the rotating member 126 includes a cylindrical portion 126B having a cylindrical outer peripheral surface 126C, and a driven gear portion 126A fixed to one end side in the axial direction of the cylindrical portion 126B. ing. Then, on the outer peripheral surface 126C of the cylindrical portion 126B, a continuous groove-shaped engagement guide portion 126D with which the protruding engagement portion 122D of the guide member 122 is engaged is formed. The continuous groove-like engagement guide portion 126D is continuously endless in the circumferential direction of the cylindrical portion outer peripheral surface 126C, and the position of the outer peripheral surface 126C in the direction parallel to the axial direction is continuous along the axial direction. It is determined to be displaced. Specifically, when the locus P on the outer peripheral surface 126C of the cylindrical portion 126B of the engagement guide portion 126 expands the outer peripheral surface 126C into a planar shape, as shown in FIG. Alternatively, it is determined so as to return to the original position at a position having a wave shape close to that and 360 [deg.]. Note that the locus of the engagement guide portion 126D on the outer circumferential surface 126C of the cylindrical portion is expressed as a peripheral shape of an elliptical cross section that appears when the cylindrical portion 126B is cut by a plane inclined with respect to the axis thereof or a shape close thereto. You can also
Here, the column portion 126B of the rotating member 126 is expressed as “column”, but this does not mean that it is limited to a solid column in a strict sense, and includes a hollow cylinder. Of course.

  Further, the cylindrical portion 126B of the rotating member 126 is inserted into the through hole 122C of the guide member 122 so as to be relatively slidable, and the protrusion-like engaging portion 122D on the inner surface of the through hole 122C has a rotating member cylindrical portion. 126B is inserted into (engaged with) a relatively grooved engagement guide portion 126D on the outer circumferential surface 126C of the engagement guide portion 126D so as to be relatively slidable in the length direction (continuous direction) of the engagement guide portion 126D.

  Here, the rotation member 126 described above is rotatably supported so that the rotation axis thereof is parallel to the rotation axis of the take-up reel 31. Then, the driven gear portion 126A on one end side of the rotating member 126 meshes with the small diameter gear 128B of the intermediate rotation transmitting body 128 as shown in FIG. The intermediate rotation transmission body 128 is obtained by superimposing the small-diameter gear 128B and the large-diameter gear 128B so as to be centered on a common axis, and has an axis parallel to the rotation axis of the take-up reel 31. It is rotatably supported as the center. The large-diameter gear 128 </ b> A of the intermediate rotation transmission body 128 meshes with the second gear 130 fixed to the first flange plate 48 </ b> B of the take-up reel 31.

Therefore, when the take-up reel 31 rotates, the rotation of the take-up reel 31 is transmitted to the rotating member 126 via the intermediate rotation transmitting body 128 and rotates about the axis. The engaging guide portion 126D of the rotating member 126 is slidably engaged with the engaging portion 122D of the guide member 122, and the position of the engaging guide portion 126D is axial as described above. Therefore, the guide member 122 is linearly moved in the direction along the rotation axis along with the rotation of the rotating member 126. In addition, since the engagement guide portion 126D is continuously endless in the circumferential direction of the cylindrical outer peripheral surface 126C, the linear motion of the guide member 122 accompanying the rotation of the rotating member 126 is a reciprocating motion of a predetermined stroke. It becomes. Here, when viewed from the operation surface as described above, the engagement guide portion 126D and the engagement portion 122D move the guide member 122 in a direction parallel to the rotation axis of the rotation member 126 when the rotation member 126 rotates. It can also be said that it is made into a shape that can be reciprocated.
Here, the gear ratio among the second gear 130, the large-diameter gear 128A, the small-diameter gear 128B, and the driven gear portion 126A is such that the rotating member 126 rotates once while the take-up reel 31 rotates six times in the illustrated example. It is stipulated to do.

  Next, the usage method of the cleaning tool 1 using the tape-shaped cleaning body 2 and an example of operation | movement of each part at the time of use are demonstrated.

  In the normal state (when not in use) shown in FIG. 19A, the container 11 is located relatively rearward with respect to the extending portion 20 and the feed mechanism 3.

  As shown in FIGS. 16, 17, and 22, if the container 11 is grasped with fingers or the like and the extension cylinder 21 of the extension portion 20 is inserted from the connector insertion port 71 of the optical adapter 70, the extension The cylindrical body 21 enters the connector receiving hole 72 while being positioned by the inner wall 70a of the optical adapter 70. Then, as shown in FIG. 22, the cleaning body 2 on the pressing surface 24 comes into contact with an appropriate position (here, the optical fiber hole 61 b and its periphery) of the joining end surface 61 a of the optical plug 60.

  As shown in FIGS. 18 and 19 (b), if a further forward force is applied to the housing 11, the distal end of the extended cylindrical body 21 reacts from the wall portion 70b of the optical adapter 70 or the like (see FIG. 22). Accordingly, the forward movement is restricted and the container 11 moves forward relative to the extending portion 20. At this time, the cylinder base 15 of the extension part 20 is accommodated in the cylinder base accommodation part 36 in a state where the rearward movement is restricted by the restriction plates 42A and 42B shown in FIG. The direction position does not change greatly. For this reason, the urging means 40 is compressed by the driving body 13 and is in a state of urging the driving body 13 backward by the reaction force from the support frame 35.

  As shown in FIG. 19B, FIG. 21, and FIG. 22, if the driving body 13 of the container 11 moves relatively forward with respect to the rotating cylinder part 82, the insertion convex part 54 is also a cam of the rotating cylinder part 82. It moves forward while being inserted into the groove 85. For this reason, the rotating shaft 52 rotates around the axis. As shown in FIG. 22, the rotation of the rotary shaft 52 causes the head member 23 to rotate about its axis, so that the tape-shaped cleaning body 2 remains in contact with the joining end surface 61a. The joint end surface 61a is wiped and cleaned by rotating around the axis.

Here, as shown in FIG. 19B, if the driving body 13 moves relative to the feed mechanism 3, a rotational force is applied to the first gear 38 by the gear receiving portion 56. Since the take-up reel 31 also rotates with the rotation of the first gear 38, the tape-shaped cleaning body 2 passes through the penetration guide portion 124 of the guide member 122 and the axial direction of the take-up reel 31 as will be described later. Is taken up by the body portion 47 of the take-up reel 31 while being moved (traversed) along the line.
Along with this, the tape-shaped cleaning body 2 is pulled out from the supply reel 30 and is fed and moved through the pressing surface 24 of the head member 23. By such a feed movement of the cleaning body 2, dirt such as dust, dust and oil adhering to the joining end surface 61 a is surely wiped off.

  After the cleaning is completed as described above, the container 11 may be moved backward when the extension portion 20 is pulled out from the optical adapter 70. At this time, the front-rear direction positions of the extending cylinder 21 and the feeding mechanism 3 with respect to the container 11 are returned to the normal state (the state shown in FIG. 19A) by the elastic force of the urging means 40.

Here, the situation when the tape-shaped cleaning body 2 is wound around the body 47B of the take-up reel 31 through the penetration guide portion 124 of the guide member 122 constituting the traverse mechanism 120, that is, the tape-shaped cleaning body. The situation when 2 is wound around the take-up reel 31 while being traversed along the axial direction of the take-up reel 31 will be described.
In this example, the axial length L of the body portion 47B between the flange portions 48B and 49B of the take-up reel 31 is the width W of the tape-shaped cleaning body 2 (hereinafter, this width W is referred to as the tape width W). It may be the same as or slightly larger than 3 times. Further, the gear ratio between the respective gears is determined so that the ratio between the rotation speed of the take-up reel 31 and the rotation speed of the rotation member 126 is 6: 1, and the straight line of the guide member 122 when the rotation member 126 further rotates. It is assumed that the dimension of the engaging guide portion 126D having a concave groove shape of the rotating member 126 is determined so that the moving distance T for one way of the reciprocating motion is twice the tape width W.

  As described above, the return tape-shaped cleaning body 2 is moved from the insertion hole 83 of the rotary cylinder portion 82 to the take-up reel 31 before being taken up by the take-up reel 31 by the rotation of the take-up reel 31. At the position, as shown in FIG. 23A to FIG. 23C, it passes through the penetration guide portion 124 of the guide member 122. Here, the rotation of the take-up reel 31 is transmitted from the second gear 130 fixed to one end of the take-up reel 31 via the large-diameter gear 128A and the small-diameter gear 128B of the intermediate rotation transmission body 128. To the driven gear portion 126A of the rotating member 126, and the rotating member 126 rotates about the axis. The rotational motion of the rotating member 126 is converted into a linear reciprocating motion by the engaging portion between the engaging guide portion 126 </ b> D and the engaging portion 122 </ b> D of the guide member 122 and transmitted to the guide member 122. Therefore, as the take-up reel 31 rotates, the guide member 122 linearly reciprocates in a direction parallel to the rotation axis. The tape-shaped cleaning body 2 passing through the penetration guide portion 124 of the guide member 122 is also reciprocated in a direction parallel to the rotation axis of the take-up reel 31 as the take-up reel 31 rotates. Accordingly, the position at which the tape-shaped cleaning body 2 is wound around the body 47B of the take-up reel 31 also reciprocates along the rotation axis of the take-up reel 31.

As described above, when the guide member 122 linearly reciprocates as the take-up reel 31 rotates, the take-up reel 31 rotates three times during one-way movement (movement distance L) of the reciprocation. FIG. 23 (A) to FIG. 23 (C) show the winding state of the three rounds of the tape-like cleaning body 2 on the body, that is, stepwise for each round.
Here, since the rotation member 126 is determined to make one rotation while the take-up reel 31 rotates six times, the guide member 122 has a one-way distance T while the take-up reel 31 rotates three times. Therefore, the winding position on the body of the take-up reel 31 is also moved one way by the distance T. Since the moving distance T is twice the tape width T, the take-up reel 31 rotates three times, and the tape-like cleaning body 2 is wound around the take-up reel 31 by three turns. When the tape-shaped cleaning body 2 passes through the penetrating guide portion 124 of the guide member 122, the tape-shaped cleaning body 2 moves by a distance twice the tape width W, and the winding position on the body portion of the take-up reel 31 is the same distance. Only move along the axial direction (traversed). Here, since the movement distance T of the tape-shaped cleaning body 2 is considered at the center in the width direction, the movement by the distance twice the tape width W as described above is three times the tape width W. It means that it is wound up in the area of width. Therefore, the tape-shaped cleaning body 2 is wound up by three turns in one layer in a region having a width three times the tape width W without being substantially overlapped (first layer).

  Then, after the take-up reel 31 has rotated three times as described above, the moving direction of the guide member 122 is reversed (that is, moved in a direction opposite to the direction shown in FIGS. 23A to 23C). Then, during the subsequent three rotations, the winding is performed on the first layer on the body of the take-up reel 31 while moving in the direction opposite to the above for the third layer as the second layer. Then, by repeating such a process, the tape-like cleaning body 2 is wound around a region having a width three times the tape width W.

  Thus, the tape-shaped cleaning body 2 wound around the take-up reel 31 moves along the axial direction along with the rotation of the take-up reel 3, and the direction of movement every three rotations. Is reversed, and three windings are taken as one layer and wound up in a region having a width three times the tape width W.

Here, the axial length L of the body portion 47B between the flange portions 48B and 49B of the take-up reel 31 is equal to or slightly larger than three times the width W of the tape-shaped cleaning body 2. Therefore, as described above, winding up to a region having a width of three times the tape width W with three rounds as one layer means that the axial length L of the take-up reel 31 is effectively used over almost the entire length. Means that And, by winding in this way, the tape-shaped cleaning body 2 of the same length is wound up as compared with the case where the winding position is not repeatedly moved (traverse) and is wound repeatedly at a certain position for each round. The thickness (lamination thickness on the take-up reel body) is remarkably small (near 1/3), and as a result, the diameter (flange diameter) D of the take-up reel 31 can be remarkably small.
Note that FIGS. 23A to 23C schematically show the situation at the time of winding simply and simply for the sake of explanation, and the positional relationship between the guide member 122 and the winding reel 31 and the actual state It should be noted that the winding position is not accurately indicated.

  In the above example, the length L between the flange portions of the take-up reel 31 is determined to be about three times the tape width W or slightly larger than that, and the guide member 122 is moved while the take-up reel 31 rotates six times. The guide member 122 is reciprocated once (in other words, the guide member 122 is moved in one direction by the distance T while the take-up reel 31 is rotated three times). However, the present invention is not limited to this. The length L between the flanges of the take-up reel 31 is set to be twice or more the tape width W, the moving distance T of the guide member 122 is set to a distance equal to or more than the tape width W, and the winding is performed while the guide member reciprocates once. The take-up reel 31 may be determined so as to rotate 2n times (where n is an arbitrary value of 2 or more).

If you generalize more desirable conditions,
A: When n is an arbitrary value of 2 or more, the axial length L of the body portion between the flange portions of the take-up reel 31 and the tape width W are:
(N + 1) · W> L ≧ n · W (1)
Satisfying the relationship
B: The number of rotations of the take-up reel 31 while the guide member 122 reciprocates once is (2 · n),
C: The reciprocating distance (one way) T in the guide member 122 of the traverse mechanism 120 and the tape width W are
n · W> T ≧ (n−1) · W (2)
Satisfying the relationship
It is desirable that the three conditions A, B, and C are satisfied at the same time. Note that n is an arbitrary value of 2 or more, but an integer of 2 or more is desirable in terms of design.
Here, if the conditions on the right side of the equations (1) and (2) are satisfied, the tape-shaped cleaning bodies 2 for the n turns do not overlap each other while the n turns are continuously wound. Thus, it can be wound in one layer. On the other hand, the condition on the left side of the equations (1) and (2) is that the length between the flange portions of the take-up reel 31 (length in the body axis direction) L does not have an excessive margin and the above n turns. This is a desirable condition for winding a single layer. Therefore, by satisfying the above conditions A, B, and C, the winding position of the tape-like cleaning body 2 is moved along the axial direction on the body portion of the take-up reel 31, and n turns. It is possible to wind up the layers in an orderly manner without overlapping, and to further reduce the diameter without giving an excessive margin to the length L between the flange portions of the take-up reel 31. .

  In the above example, the guide member 122 reciprocates once while the rotating member 126 makes one rotation. However, in some cases, the guide member 122 reciprocates a plurality of times while the rotating member 126 makes one rotation. It is good also as a structure which moves. For example, an example in which the guide member 122 is configured to reciprocate twice during one rotation of the rotating member 126 is a developed view of the outer peripheral surface 126C of the columnar portion of the rotating member 126. FIG. FIG. 24B shows the same as FIG. In this case, it is determined that the wavy locus P of the engagement guide portion 126D is repeated for two waves on one circumference of the cylindrical portion outer peripheral surface 126C.

  In the above-described example, the engagement guide portion 126D formed on the outer peripheral surface 126C of the cylindrical portion 126B of the rotating member 126 is formed into a continuous concave groove shape, and the engagement portion 122D of the guide member 122 engaged with the engagement guide portion 122D is formed. In some cases, on the contrary, in some cases, the engagement guide portion 126D of the outer peripheral surface 126C of the cylindrical portion 126B of the rotating member 126 is formed into a continuous protrusion shape (continuous protrusion), and the guide member 122 engaged therewith is engaged. It is also permissible for the engaging portion 122D to be a concave groove.

  Further, as described above, the penetrating guide portion 124 of the guide member 122 has an interval in the direction parallel to the rotation axis 31 of the take-up reel 31 (therefore, the linear reciprocating direction of the guide member 122) in the cross-sectional shape of the inner space. For example, the cross-sectional shape is rectangular or elliptical so that the interval in the direction perpendicular to the tape width W is slightly smaller than the tape width W and smaller than the tape width W. By forming the tape-shaped cleaning body 2, the tape-shaped cleaning body 2 is guided toward the take-up reel 31 while maintaining a state in which the width direction thereof is along the axial direction of the take-up reel 31. It becomes easy to orderly wind the tape-like cleaning body 2 on the body portion while maintaining a posture in which the wide surface is parallel to the rotation axis.

  In the illustrated example, a two-stage gear in which a large-diameter gear 128 </ b> A and a small-diameter gear 128 </ b> B are overlapped is used as the intermediate rotation transmitting body 128. (6: 1 in the illustrated example), and in some cases, one may be omitted to form a one-stage gear. Further, in some cases, the intermediate rotation transmission body 128 itself may be omitted, and the second gear 130 fixed to the take-up reel 31 may be configured to directly mesh with the driven gear portion 126A of the rotating member 126.

  The cleaning tool of the present invention can be applied to various types of optical fiber connectors. For example, an LC type optical connector (trademark of Lucent), an SC type optical connector established by JIS C 5973 (SC: Single fiber). It can be applied to a single optical fiber connector such as a coupling optical fiber connector (MU), a MU type optical connector established in JIS C 5983 (MU: Miniature-unit coupling optical fiber connector), or an SC2 type optical connector. Here, the SC2 type optical connector is obtained by omitting a knob attached to the outside of the housing from the SC type optical connector.
