Description

【0001】
【発明の属する技術分野】
本発明は、光伝送体アレイ用の棒状レンズを複数本束ねて梱包する前に、棒状レンズを整列させる方法に関する。
【0002】
【従来の技術】
近年、多くのLEDプリンタやスキャナ等に、画像伝送体として光伝送体アレイ(ロッドレンズアレイともいう。)が組み込まれている。光伝送体アレイは、一般に、二枚の基板と、それらの間に並列に配列された、光伝送性を有する多数本の棒状レンズ(ロッドレンズともいう。)から構成されている。光伝送体アレイを構成する個々の棒状レンズの直径は、通常、1mm以下である。そして、棒状レンズの直径が細く、棒状レンズの配列間隔が狭くなるほど、光伝送体の解像度が高くなる。
【0003】
光伝送体アレイの製造においては、製造工程によって工場が異なることがある。その場合、細い棒状レンズを梱包して、次の工程を行う工場まで運搬する必要がある。棒状レンズの梱包にあたっては、数千本程度の棒状レンズの束を梱包袋に入れたユニット(簀巻きユニット)を作り、複数個の簀巻きユニットを梱包箱内に俵積状に詰め込んでいる。簀巻きユニットを作る際には、作業員が、ラック等に保管されていた棒状レンズの束を手で掴んで梱包袋に入れ、次いで、棒状レンズの束の両端を揃えてから、梱包袋の余り代を周囲に巻き付け、テープ等で固定していた。
【0004】
【発明の解決しようとする課題】
ところで、単に手で掴んで梱包袋に入れられた棒状レンズの間には、多くの隙間が残っている。このような隙間を多く残したままの簀巻きユニットを梱包しすると、輸送中に簀巻きユニット内で個々の棒状レンズどうしが動くため、棒状レンズに変形や疵が生じ、棒状レンズの品質が劣化することがある。
【0005】
そこで、本発明は、棒状レンズ間の隙間を容易に減らすことができる棒状レンズの整列方法を提供することを目的としている。
【0006】
【課題を解決するための手段】
上記の目的を達成するため、本発明の棒状レンズの整列方法は、複数本の棒状レンズを整列させる方法であって、棒状レンズの長さよりも長い間隔を隔てて向かい合った二つの対向面を有する枠部と、これらの対向面に両端を向けて配置した樋形状の受け部とから構成された整列用ユニットを準備する第一ステップと、受け部に複数本の棒状レンズを載せる第二ステップと、整列用ユニットを揺することにより、棒状レンズを長手方向に往復運動させて整列させる第三ステップと、受け部を上記枠部から持ち上げて、棒状レンズを受け部から取り出す第四ステップと、を有することを特徴とする。
【0007】
このように、本発明によれば、複数本の棒状レンズを容易に整列させて、棒状レンズ間の隙間を減らすことができる。これにより、棒状レンズの束を、棒状レンズ間に隙間が少ない状態にして梱包することができる。その結果、棒状レンズの輸送中に、棒状レンズの束内で、個々の棒状レンズの動きを抑制することができる。このため、棒状レンズどうしが動いて、変形や疵が生じて品質が劣化することを回避することができる。
【0008】
また、本発明において、好ましくは、第一ステップにおいて、受け部は、半円筒形である。
このように、受け部を半円筒形とすれば、棒状レンズを効率的に整列させることができる。
【0009】
また、本発明において、好ましくは、第一ステップにおいて、受け部の樋形状の軸線方向の長さは、棒状レンズの長さよりも短い。
このようにすれば、第四ステップにおいて、受け部からはみ出した棒状レンズの部分を容易に掴むことができる。その結果、棒状レンズを整列させたまま容易に取り出すことができる。
【0010】
また、本発明において、好ましくは、第三ステップにおいて、棒状レンズに荷重をかけた状態で、棒状レンズを往復運動させる。
このようにすれば、棒状レンズを効率的に整列させることができる。
【0011】
また、本発明において、好ましくは、第四ステップにおいて、受け部を、可撓性を有する材料で作っておき、受け部を持ち上げる際に、受け部の樋形状の両縁どうしを近づけて、棒状レンズを上記樋形状の中央に集める。
このように、棒状レンズを樋形状の中央に寄せれば、棒状レンズを整列させたまま、掴み易くすることができる。その結果、棒状レンズを整列させたまま容易に取り出すことができる。
【0012】
【発明の実施の形態】
以下、添付の図面を参照して、本発明の棒状レンズの整列方法の実施形態を説明する。
複数本の棒状レンズを整列させるにあたり、まず、第一ステップとして、整列用ユニットを準備する。ここで、図1に、本実施形態の整列用ユニットを示す。図1(A)は、整列用ユニットの分離斜視図であり、図1(B)は、整列用ユニットの側方断面図である。
【0013】
図1に示すように、本実施形態の整列用ユニットは、枠部10と受け部20とから構成されている。なお、図1(A)においては、整列用ユニットの構成の理解を容易にするために、枠部10と受け部20とを、縦方向に分離させて示している。
【0014】
枠部10は、向かい合った二つの対向面11a及び11bを有する。本実施形態では、更に枠部10に底12を設けて、枠部10を箱形の形状としている。そして、本実施形態では、枠部10は、厚さ2mmの樹脂板を組み合わせて形成されており、その寸法は、長さL=200mm、幅W=100mm、深さD=30mmである。
【0015】
なお、本実施形態では、長さL=166mmのプラスチック製の棒状レンズ30を整列させるので、枠部10の対向面どうしの間隔(枠部10の長さLから対向面部分の厚み分を減じた値となる。)を、棒状レンズ30の長さLよりも長くしている。また、対向面どうしの間隔は、棒状レンズの長さの120〜140%が好ましい。
【0016】
また、受け部20は、半円筒形の樋形状を有し、樋形状の両端21a及び22bを、枠部10の対向面11a及び11bに向けて配置されている。本実施形態では、受け部20は、可撓性を有するように塩化ビニル樹脂等の樹脂材料で作られている。そして、本実施形態では、受け部20の樋形状の軸線方向の長さL=130mm、樋形状の半円筒形の曲率半径は30〜45mmである。
【0017】
なお、本実施形態では、受け部20の長さLを、棒状レンズ30の長さLよりも短くしている。また、整列後の棒状レンズ30を受け部20から取り出し易くするため、受け部20の長さは、棒状レンズの長さの30〜80%が好ましい。
【0018】
次に、第二ステップとして、受け部20に複数本の棒状レンズ30を載せる。本実施形態では、作業員が、長さ166mm、直径0.6mmの棒状レンズ約5000本を手で掴んで、図2(A)に示すように、受け部20に載せる。なお、受け部20に一度に載せる棒状レンズの量は特に限定されないが、例えば100〜300グラム程度が作業効率上好ましい。
【0019】
次に、第三ステップとして、整列用ユニットを揺することにより、棒状レンズ30を長手方向に往復運動させて整列させる。
本実施形態では、図2(B)に示すように、整列用ユニットを長手方向に水平方向(図2(B)中の矢印の方向)に振動させる。そして、振動により棒状レンズが往復運動した結果、棒状レンズが実質的に最密に整列する。また、棒状レンズ30の束の端は、棒状レンズ30を対向面11a又は11bに当てることにより容易に揃えることができる。
なお、整列用ユニットの振動振幅及び振動周期等の振動条件は、任意好適なものとすることができる。
【0020】
ここで、図3に、棒状レンズ間の隙間の変化の様子を模式的に示す。図3(A)は、整列前の棒状レンズの束の端部を拡大して模式的に示し、図3(B)は、整列後の棒状レンズの束の端部を拡大して模式的に示す。棒状レンズを長手方向に往復運動させると、図3(A)に示したような余計な隙間が、図3(B)に示すように実質的になくなる。
【0021】
なお、棒状レンズを往復運動させると、棒状レンズの自重によって、棒状レンズが整列するが、更に棒状レンズに荷重をかけた状態で、棒状レンズを往復運動させてもよい。ただし、荷重が大きすぎると、摩擦により却って整列を妨げることになる。このため、荷重の大きさは、圧力にして50kPa以下となるようにするのが好ましい。
【0022】
次に、第四ステップとして、受け部20を枠部10から持ち上げて、棒状レンズ30を受け部20から取り出す。
本実施形態は、図4(A)に示すように、受け部20の樋形状の両縁22a及び22bを近づけながら、受け部20を持ち上げる。受け部20は、弾力性があるので、作業員が片手で受け部20の両縁22a及び22bに指を掛けて持ち上げることにより、容易に受け部20を絞ることができる。
そして、図4(B)に示すように、受け部20が絞られることにより、棒状レンズ30が樋形状の中央に集められる。このため、作業員は、棒状レンズの束の、受け部20からはみ出している部分を、もう片方の手で、棒状レンズを整列させたまま容易に掴むことができる。
【0023】
さらに、受け部20から取り出された棒状レンズの束をそのまま梱包袋に入れて簀巻きユニットを作る。これにより、棒状レンズを余計な隙間が実質的にない状態で梱包することができる。その結果、棒状レンズの輸送中、個々の棒状レンズの動きを抑制することができる。このため、棒状レンズどうしが動いて、変形や疵が生じて品質が劣化することを回避することができる。
【0024】
上述した各実施形態においては、本発明を特定の条件で構成した例について説明したが、本発明は種々の変更及び組み合わせを行うことができ、これに限定されるものではない。
例えば、上述した実施形態では、棒状レンズとして、プラスチック製のロッドレンズを使用した例について説明したが、本発明では、棒状レンズとしてガラス製のロッドレンズを使用してもよい。
また、上述した実施形態では、受け部の樋形状を半円筒形として例について説明したが、本発明では、受け部の樋形状はこれに限定されない。
また、上述した実施形態では、枠部及び受け部を樹脂で作った例について説明したが、枠部及び受け部の材料はこれに限定されない。
また、上述した実施形態では、整列用ユニットを水平方向に振動させた例について説明したが、本発明では、整列用ユニットを反対方向に交互に傾斜させて、棒状レンズを往復運動させてもよい。
【0025】

[0011]
In the present invention, preferably, in the fourth step, the receiving portion is made of a flexible material, and when the receiving portion is lifted, both edges of the gutter shape of the receiving portion are brought close to each other to form a rod. The lenses are collected in the center of the gutter shape.
In this way, if the rod-shaped lens is moved to the center of the gutter shape, it is possible to easily grasp the rod-shaped lens while keeping the rod-shaped lens aligned. As a result, the rod-shaped lenses can be easily taken out while being aligned.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a rod-shaped lens alignment method of the present invention will be described with reference to the accompanying drawings.
In order to align a plurality of rod-shaped lenses, first, as a first step, an alignment unit is prepared. Here, FIG. 1 shows an alignment unit of the present embodiment. FIG. 1A is an exploded perspective view of the alignment unit, and FIG. 1B is a side sectional view of the alignment unit.
[0013]
As shown in FIG. 1, the alignment unit according to the present embodiment includes a frame portion 10 and a receiving portion 20. In FIG. 1A, the frame portion 10 and the receiving portion 20 are separated from each other in the vertical direction to facilitate understanding of the configuration of the alignment unit.
[0014]
The frame 10 has two opposing surfaces 11a and 11b facing each other. In the present embodiment, the bottom portion 12 is further provided on the frame portion 10 so that the frame portion 10 has a box shape. In the present embodiment, the frame portion 10 is formed by combining a resin plate having a thickness of 2 mm, and the dimensions are length L 1 = 200 mm, width W = 100 mm, and depth D = 30 mm.
[0015]
In the present embodiment, since the plastic rod-shaped lenses 30 having a length L 3 = 166 mm are aligned, the distance between the opposing surfaces of the frame 10 (from the length L 1 of the frame 10 to the thickness of the opposing surface is equal to the thickness of the opposing surface). the.) as a value obtained by subtracting the, it is longer than the length L 3 of the rod-like lenses 30. The distance between the opposing surfaces is preferably 120 to 140% of the length of the rod-shaped lens.
[0016]
The receiving portion 20 has a semi-cylindrical gutter shape, and both ends 21 a and 22 b of the gutter shape are arranged to face the facing surfaces 11 a and 11 b of the frame portion 10. In the present embodiment, the receiving portion 20 is made of a resin material such as a vinyl chloride resin so as to have flexibility. In the present embodiment, the receiving portion 20 of the trough-shaped axial length L 2 = 130 mm, the radius of curvature of the semi-cylindrical trough shape is 30~45Mm.
[0017]
In the present embodiment, the length L 2 of the receiving portion 20, is made shorter than the length L 3 of the rod-like lenses 30. In addition, the length of the receiving portion 20 is preferably 30 to 80% of the length of the rod-shaped lens in order to make it easy to take out the aligned rod-shaped lens 30 from the receiving portion 20.
[0018]
Next, as a second step, a plurality of rod-shaped lenses 30 are placed on the receiving portion 20. In this embodiment, an operator grasps by hand about 5000 rod-shaped lenses having a length of 166 mm and a diameter of 0.6 mm, and places them on the receiving portion 20 as shown in FIG. In addition, the amount of the rod-shaped lens placed on the receiving portion 20 at one time is not particularly limited, but for example, about 100 to 300 grams is preferable in terms of work efficiency.
[0019]
Next, as a third step, the rod-shaped lens 30 is reciprocated in the longitudinal direction to be aligned by shaking the alignment unit.
In the present embodiment, as shown in FIG. 2B, the alignment unit is vibrated in the longitudinal direction in the horizontal direction (the direction of the arrow in FIG. 2B). Then, as a result of the reciprocating movement of the rod-shaped lens due to the vibration, the rod-shaped lenses are substantially aligned in the closest density. The ends of the bundle of the rod-shaped lenses 30 can be easily aligned by applying the rod-shaped lenses 30 to the opposing surface 11a or 11b.
The vibration conditions such as the vibration amplitude and the vibration period of the alignment unit can be arbitrarily suitable.
[0020]
Here, FIG. 3 schematically shows how the gap between the rod-shaped lenses changes. FIG. 3A schematically shows an enlarged end of the bundle of rod-shaped lenses before alignment, and FIG. 3B schematically shows an enlarged end of the bundle of rod-shaped lenses after alignment. Show. When the rod-shaped lens is reciprocated in the longitudinal direction, an unnecessary gap as shown in FIG. 3A is substantially eliminated as shown in FIG.
[0021]
When the rod-shaped lens is reciprocated, the rod-shaped lenses are aligned by the weight of the rod-shaped lens. However, the rod-shaped lens may be reciprocated while a load is further applied to the rod-shaped lens. However, if the load is too large, the friction will hinder the alignment. For this reason, it is preferable that the magnitude of the load be 50 kPa or less in terms of pressure.
[0022]
Next, as a fourth step, the receiving part 20 is lifted from the frame part 10 and the rod-shaped lens 30 is taken out from the receiving part 20.
In the present embodiment, as shown in FIG. 4A, the receiving portion 20 is lifted while the gutter-shaped edges 22a and 22b of the receiving portion 20 are brought close to each other. Since the receiving portion 20 has elasticity, the worker can easily squeeze the receiving portion 20 by lifting the both edges 22a and 22b of the receiving portion 20 with one hand with fingers.
Then, as shown in FIG. 4 (B), the rod-shaped lens 30 is gathered at the center of the gutter shape by narrowing the receiving portion 20. Therefore, the operator can easily grasp the portion of the bundle of rod-shaped lenses protruding from the receiving portion 20 with the other hand while keeping the rod-shaped lenses aligned.
[0023]
Further, the bundle of rod-shaped lenses taken out of the receiving portion 20 is directly put in a packing bag to make a wrapping unit. Thereby, the rod-shaped lens can be packed in a state where there is substantially no extra gap. As a result, the movement of each rod-shaped lens can be suppressed during the transportation of the rod-shaped lens. For this reason, it is possible to prevent the rod-shaped lenses from moving and causing deformation or flaws to deteriorate the quality.
[0024]
In each of the embodiments described above, examples in which the present invention is configured under specific conditions have been described. However, the present invention can be variously changed and combined, and the present invention is not limited to this.
For example, in the above-described embodiment, an example in which a plastic rod lens is used as the rod lens has been described. However, in the present invention, a glass rod lens may be used as the rod lens.
Further, in the above-described embodiment, an example was described in which the gutter shape of the receiving portion was a semi-cylindrical shape. However, in the present invention, the gutter shape of the receiving portion is not limited to this.
Further, in the above-described embodiment, an example has been described in which the frame portion and the receiving portion are made of resin, but the material of the frame portion and the receiving portion is not limited to this.
Further, in the above-described embodiment, an example in which the alignment unit is vibrated in the horizontal direction has been described. However, in the present invention, the alignment unit may be alternately inclined in the opposite direction to reciprocate the rod-shaped lens. .
[0025]
【The invention's effect】
As described above, according to the present invention, the gap between the rod-shaped lenses can be easily reduced.
