以下、本発明の実施の形態について図面を参照して説明する。
本発明の光学素子の梱包方法で使用する光学素子としては、例えば、ＬＥＤ用レンズなどの大型レンズが好適である。特に、光学素子の表面に透過性を高めるコーティングを施していない光学素子が好ましい。すなわち、透過効率を厳しく問われるレンズではなく、配光特性が問われるレンズが好ましい。したがって、レンズ表面を直接触れても性能に影響が出にくいものである。
本発明に好適な光学素子の大きさとしては、比較的直径が大きく、φ２０〜φ１００位である。また、光学素子は樹脂材料からなることが好ましい。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As an optical element used in the optical element packaging method of the present invention, for example, a large lens such as an LED lens is suitable. In particular, an optical element in which the surface of the optical element is not coated with a coating that enhances permeability is preferable. That is, it is preferable to use a lens that requires light distribution characteristics, rather than a lens that requires strict transmission efficiency. Therefore, even if the lens surface is directly touched, the performance is hardly affected.
The size of the optical element suitable for the present invention is relatively large in diameter and is about φ20 to φ100. The optical element is preferably made of a resin material.

［第１の実施形態］
図１は、第１の実施形態における光学素子の梱包方法を示した外観斜視図である。
本発明の光学素子の梱包方法は、図１に示すように、シートの表面に粘着剤を塗布してなる粘着テープ１上に、複数の光学素子１００を所定間隔で直接貼り付ける。そして、貼り付けた光学素子１００の上面１００aに、さらに粘着テープ１を重ねて、当該粘着テープ１上に複数の光学素子１００を直接貼り付ける。このようにして粘着テープ１と複数の光学素子１００とを、この順に複数段重ねることによって梱包物１０とする。 [First Embodiment]
FIG. 1 is an external perspective view showing a method for packing optical elements in the first embodiment.
In the optical element packaging method of the present invention, as shown in FIG. 1, a plurality of optical elements 100 are directly pasted at predetermined intervals on an adhesive tape 1 formed by applying an adhesive to the surface of a sheet. Then, the adhesive tape 1 is further stacked on the upper surface 100 a of the optical element 100 that is pasted, and the plurality of optical elements 100 are directly pasted on the adhesive tape 1. In this way, the adhesive tape 1 and the plurality of optical elements 100 are stacked in this order to form the package 10.

なお、図１では、図面の関係上、１段目の光学素子１００と、２段目の粘着テープ１との間に空間が形成されているが、実際には１段目の光学素子１００の上面１００aと２段目の粘着テープ１の下面１bとは接触している。また、この図１では、粘着テープ１及び光学素子１００はそれぞれ２段に重ねられているが、１段であっても良いし、３段以上としても良い。
また、図１では、横方向（図１では粘着テープ１の長手方向）に隣接する光学素子１００同士は互いに所定間隔を空けて配置し、かつ、縦方向（図１では粘着テープ１の幅手方向）に隣接する光学素子同士１００は、一方を横方向にずらした千鳥配列となっている。なお、光学素子１００の貼り付けパターンは、これに限らず適宜変更しても良い。 In FIG. 1, a space is formed between the first-stage optical element 100 and the second-stage adhesive tape 1 for the sake of illustration. The upper surface 100a and the lower surface 1b of the second-stage adhesive tape 1 are in contact with each other. In FIG. 1, the adhesive tape 1 and the optical element 100 are each overlapped in two stages, but may be one stage or three or more stages.
In FIG. 1, the optical elements 100 adjacent in the horizontal direction (the longitudinal direction of the adhesive tape 1 in FIG. 1) are arranged at a predetermined interval from each other, and in the vertical direction (the width of the adhesive tape 1 in FIG. 1). The optical elements 100 adjacent to each other in the direction) have a staggered arrangement in which one side is shifted in the horizontal direction. The attachment pattern of the optical element 100 is not limited to this and may be changed as appropriate.

光学素子１００の粘着テープ１への貼り付け面１００b（光学素子１００の下面）は平面であっても良いし、粗しパターンが形成されていても良い。光学素子１００の貼り付け面１００bが平面の場合、粘着力が、２．０Ｎ／１０ｍｍ以下であることが好ましい。また、光学素子１００の貼り付け面１００bに粗しパターンがある場合には、粘着力が、３．０Ｎ／１０ｍｍ以下であることが好ましい。ここで言う粘着力は、剥離速度３００ｍｍ／ｓｅｃ、剥離角１８０度の条件下で測定したものである。
粘着テープ１は、光学素子１００を剥がした際に粘着剤が光学素子１００に影響しない範囲で着かないことが重要であり、具体的には、日東電工製のＳＰＶシリーズ等を使用することが好ましい。
粘着テープ１の厚さは、４０μｍ以上１３０μｍ以下であることが好ましい。粘着テープ１が４０μｍより薄い場合には、粘着テープ１に腰が無く、粘着テープ１の光学素子１００が貼り付けられていない部分が撓んだりして変形するためである。１３０μｍより厚い場合は、光学素子１００の貼り付け面１００bに粗しがあると、密着性が悪くなるためである。 The bonding surface 100b (the lower surface of the optical element 100) of the optical element 100 to the adhesive tape 1 may be a flat surface or a rough pattern may be formed. When the bonding surface 100b of the optical element 100 is a flat surface, the adhesive strength is preferably 2.0 N / 10 mm or less. Moreover, when there exists a rough pattern in the affixing surface 100b of the optical element 100, it is preferable that adhesive force is 3.0 N / 10mm or less. The adhesive force mentioned here is measured under conditions of a peeling speed of 300 mm / sec and a peeling angle of 180 degrees.
It is important that the adhesive tape 1 does not arrive within the range where the adhesive does not affect the optical element 100 when the optical element 100 is peeled off. Specifically, it is preferable to use a Nitto Denko SPV series or the like. .
The thickness of the adhesive tape 1 is preferably 40 μm or more and 130 μm or less. This is because when the pressure-sensitive adhesive tape 1 is thinner than 40 μm, the pressure-sensitive adhesive tape 1 is not elastic and a portion of the pressure-sensitive adhesive tape 1 where the optical element 100 is not attached is bent or deformed. This is because when the thickness is larger than 130 μm, the adhesiveness deteriorates if the attachment surface 100b of the optical element 100 is rough.

［第２の実施形態］
図２は、第２の実施形態における光学素子の梱包方法を示した外観斜視図である。
第２の実施形態では、図２に示すように、第１の実施形態とは異なり、粘着テープ１上に貼り付けた光学素子１００と、当該光学素子１００上に重ねる上段の粘着テープ１との間に、衝撃緩衝材として使用されるエアーパッキン２を配置する。なお、衝撃緩衝材としては、エアーパッキン２以外に、ウレタン樹脂、スチレン樹脂、ポチエチレンテレフタレート樹脂等の発泡樹脂シートを使用しても良い。
なお、図２では、図面の関係上、１段目の光学素子１００とエアーパッキン２との間、エアーパッキン２と２段目の粘着テープ１との間にそれぞれ空間が形成されているが、実際には１段目の光学素子１００の上面１００aとエアーパッキン２の下面及びエアーパッキン２の上面と２段目の粘着テープ１の下面１bとは接触している。
エアーパッキン２は、粘着テープ１と同形状で同じ大きさをなしており、光学素子１００の上面１００aと粘着シート１の下面１bとの間に設けることで、このエアーパッキン２の空気層によって、振動による衝撃を緩和して光学素子１００への傷を防止することができる。 [Second Embodiment]
FIG. 2 is an external perspective view showing a method for packing optical elements in the second embodiment.
In the second embodiment, as shown in FIG. 2, unlike the first embodiment, the optical element 100 attached on the adhesive tape 1 and the upper adhesive tape 1 stacked on the optical element 100 are provided. An air packing 2 used as an impact buffering material is disposed between them. In addition to the air packing 2, a foamed resin sheet such as a urethane resin, a styrene resin, or a polyethylene terephthalate resin may be used as the shock absorbing material.
In FIG. 2, spaces are formed between the first-stage optical element 100 and the air packing 2, and between the air packing 2 and the second-stage adhesive tape 1, for the sake of illustration. Actually, the upper surface 100a of the first-stage optical element 100 and the lower surface of the air packing 2 and the upper surface of the air packing 2 and the lower surface 1b of the second-stage adhesive tape 1 are in contact.
The air packing 2 has the same shape and the same size as the pressure-sensitive adhesive tape 1, and is provided between the upper surface 100 a of the optical element 100 and the lower surface 1 b of the pressure-sensitive adhesive sheet 1. It is possible to mitigate the impact caused by the vibration and prevent the optical element 100 from being damaged.

また、図３に示すように、粘着テープ１、光学素子１００、エアーパッキン２をこの順に重ねて、複数段形成した後、これら粘着テープ１、光学素子１００、エアーパッキン２をビニール袋（容器）３内に収容した後に、真空引きすることが好ましい。なお、ビニール袋３に限らず、真空引き可能なケース等を使用しても良い。
また、ビニール袋３の底面及び天井面にはそれぞれダンボール板４を配置しておくことが好ましい。ダンボール板４を配置することで、最下段の粘着シート１や最上段のエアーパッキン２が撓むことなく所定位置で固定することができる。
真空引きは、例えば、ビニール袋に吸引口を設けておき、この吸引口から真空引きすることで行う。複数段に重ねられた粘着テープ１、光学素子１００、エアーパッキン２の全体をビニール袋３に入れて真空引きすることによって、粘着テープ１及びエアーパッキン２同士が密着し、耐衝撃性の確保と荷崩れ防止の両面で有利となる。 Also, as shown in FIG. 3, after the adhesive tape 1, the optical element 100, and the air packing 2 are stacked in this order to form a plurality of stages, the adhesive tape 1, the optical element 100, and the air packing 2 are placed in a plastic bag (container). It is preferable to evacuate after accommodating in 3. In addition, you may use not only the plastic bag 3 but the case etc. which can be evacuated.
Moreover, it is preferable to arrange the corrugated board 4 on the bottom surface and the ceiling surface of the plastic bag 3, respectively. By disposing the corrugated cardboard plate 4, the lowermost adhesive sheet 1 and the uppermost air packing 2 can be fixed at predetermined positions without being bent.
The evacuation is performed, for example, by providing a suction port in a plastic bag and evacuating from the suction port. The adhesive tape 1, the optical element 100, and the air packing 2 stacked in a plurality of stages are placed in a plastic bag 3 and evacuated, so that the adhesive tape 1 and the air packing 2 are in close contact with each other, ensuring impact resistance. This is advantageous in terms of preventing cargo collapse.

次に、粘着テープ１、光学素子１００及びエアーパッキン２を重ねて梱包する具体的な手順について、自動梱包装置２００とともに説明する。
自動梱包装置２００としては、例えば、図４に示すように、ロール状に巻かれた粘着テープ１やエアーパッキン２をそれぞれ引き出す引き出し手段と、引き出した粘着テープ１やエアーパッキン２を所定長さで断裁する自動断裁機２０２，２０４と、断裁後の粘着テープ１上に複数の光学素子１００を直接貼り付ける貼り付け手段（図示しない）と、コンベアー２０５と、光学素子１００貼り付け後の粘着テープ１をコンベアー２０５に載置する粘着テープ載置手段（図示しない）と、断裁後のエアーパッキン２をコンベアー２０５に載置した光学素子１００上に重ねるエアーパッキン載置手段（図示しない）等を備えたものが挙げられる。
粘着テープ１やエアーパッキン２を引き出す引き出し手段としては、例えば、モーター等の駆動源（図示しない）によって回転駆動自在な元巻きローラー２０１，２０３と、元巻きローラー２０１，２０３によって引き出された粘着テープ１又はエアーパッキン２を表面で支持するとともに搬送する搬送ローラー（図示しない）等からなるものが挙げられる。
貼り付け手段としては、例えば、光学素子１００を吸着して粘着テープ１上に貼り付ける吸着装置（図示しない）等が挙げられる。 Next, a specific procedure for stacking the adhesive tape 1, the optical element 100, and the air packing 2 together with the automatic packing apparatus 200 will be described.
As the automatic packing device 200, for example, as shown in FIG. 4, a pull-out means for pulling out the adhesive tape 1 and the air packing 2 wound in a roll shape, and the pulled-out adhesive tape 1 and the air packing 2 with a predetermined length. Automatic cutting machines 202 and 204 for cutting, an attaching means (not shown) for directly attaching a plurality of optical elements 100 onto the adhesive tape 1 after cutting, a conveyor 205, and an adhesive tape 1 after the optical elements 100 are attached Adhesive tape placement means (not shown) for placing the air packing 2 on the conveyor 205, air packing placement means (not shown) for stacking the cut air packing 2 on the optical element 100 placed on the conveyor 205, and the like. Things.
As a pull-out means for pulling out the adhesive tape 1 and the air packing 2, for example, the original winding rollers 201 and 203 that can be driven to rotate by a driving source (not shown) such as a motor, and the adhesive tape drawn out by the original winding rollers 201 and 203 are used. 1 or the air packing 2 is supported on the surface, and includes a conveyance roller (not shown) that conveys the material.
Examples of the affixing means include an adsorbing device (not shown) that adsorbs the optical element 100 and affixes it on the adhesive tape 1.

このような自動梱包装置２００では、まず、元巻きローラー２０１をモーター等により回転駆動させてロール状に巻かれた粘着テープ１を引き出しつつ、吸着装置等で吸着した光学素子１００を、引き出した粘着テープ１上に複数所定位置に貼り付ける。
次いで、自動断裁機２０２を使用して、光学素子１００が貼り付けられた粘着テープ１を所定長さで断裁してシート状とし、これをコンベアー２０５上に載置する。
一方、元巻きローラー２０３をモーター等により回転駆動させてロール状に巻かれたエアーパッキン２を引き出して、自動断裁機２０４によって、所定長さで断裁してシート状とし、このエアーパッキン２をコンベアー２０５に載置された粘着テープ１上の光学素子１００に対して重ねる。
再び、ロール状に巻かれた粘着テープ１を引き出しつつ、引き出した粘着テープ１上に複数の光学素子１００を貼り付け、粘着テープ２を断裁した後、コンベアー２０５に載置されたエアーパッキン２上に、当該光学素子１００が貼り付けられた粘着テープ１を重ねる。さらに、この光学素子１００に対して、断裁したエアーパッキン２を重ねる。このような動作を繰り返して、粘着テープ１、光学素子１００、エアーパッキン２をこの順に順次重ねて所定の段数となったら、この梱包物１０をコンベアー２０５で搬送する。
搬送後、上述したようにビニール袋３内に収容し、真空引きしても良い。 In such an automatic packing apparatus 200, first, the original winding roller 201 is driven to rotate by a motor or the like, and the adhesive tape 1 wound in a roll shape is pulled out, while the optical element 100 adsorbed by the suction apparatus or the like is pulled out. A plurality of pieces are stuck on the tape 1 at predetermined positions.
Next, the automatic cutting machine 202 is used to cut the adhesive tape 1 to which the optical element 100 is attached to a predetermined length to form a sheet, which is placed on the conveyor 205.
On the other hand, the original packing roller 203 is driven to rotate by a motor or the like, and the air packing 2 wound in a roll shape is pulled out and cut into a sheet shape by a predetermined length by an automatic cutting machine 204. The air packing 2 is conveyed by a conveyor. The optical element 100 on the adhesive tape 1 placed on 205 is overlapped.
Again, while pulling out the adhesive tape 1 wound in a roll shape, a plurality of optical elements 100 are attached on the drawn adhesive tape 1, the adhesive tape 2 is cut, and then on the air packing 2 placed on the conveyor 205. Further, the adhesive tape 1 to which the optical element 100 is attached is overlaid. Further, the cut air packing 2 is stacked on the optical element 100. When such an operation is repeated and the adhesive tape 1, the optical element 100, and the air packing 2 are sequentially stacked in this order to reach a predetermined number of stages, the package 10 is conveyed by the conveyor 205.
After the conveyance, it may be accommodated in the plastic bag 3 as described above and evacuated.

図５は、図４の変形例を示した図である。すなわち、図４とは異なり、ロール状の粘着テープ１及びロール状のエアーパッキン２を断裁せずに、そのまま重ねて梱包していく。
ここで使用する自動梱包装置２００Ａは、図４のような自動断裁機２０２，２０４やコンベアー２０５、粘着テープ載置手段及びエアーパッキン載置手段を必要としないが、ロール状の粘着テープ１上に貼り付けられた光学素子１００及び当該光学素子１００上に重ねられたロール状のエアーパッキン２を巻き取る製品巻取りローラー２０６Ａを備える。
具体的に、図５(a)に示すように、元巻きローラー２０１Ａをモーター等により回転駆動させてロール状に巻かれた粘着テープ１を引き出しつつ、吸着装置等で吸着した光学素子１００を、引き出した粘着テープ１上に複数所定位置に貼り付ける。
一方、元巻きローラー２０３をモーター等により回転駆動させてロール状に巻かれたエアーパッキン２を引き出しつつ、粘着テープ１に貼り付けられた光学素子１００上に随時重ねていく。この際に、重ねられた粘着テープ１、光学素子１００及びエアーパッキン２を製品巻き取りローラー２０６Ａによって巻き取る。巻き取られた梱包物１０は、図５(b)に示すように、ロール状で収容箱２０７Ａ等にコンパクトに収容することができる。 FIG. 5 is a diagram showing a modification of FIG. That is, unlike FIG. 4, the roll-shaped adhesive tape 1 and the roll-shaped air packing 2 are stacked as they are without being cut.
The automatic packing apparatus 200A used here does not need the automatic cutting machines 202 and 204, the conveyor 205, the adhesive tape placing means and the air packing placing means as shown in FIG. A product take-up roller 206 </ b> A for taking up the optical element 100 that is pasted and the roll-shaped air packing 2 stacked on the optical element 100 is provided.
Specifically, as shown in FIG. 5 (a), the optical element 100 adsorbed by an adsorption device or the like while pulling out the adhesive tape 1 wound in a roll shape by rotating the original winding roller 201A by a motor or the like, A plurality of adhesive tapes 1 are affixed at predetermined positions.
On the other hand, the original winding roller 203 is rotationally driven by a motor or the like, and the air packing 2 wound in a roll shape is pulled out, and is superposed on the optical element 100 attached to the adhesive tape 1 as needed.

以上のように、本実施形態によれば、複数の光学素子１００を粘着テープ１上に直接貼り付けるだけで、光学素子１００を容易に梱包することができるとともに光学素子１００を確実に粘着テープ１上に固定することができる。
また、粘着テープ１上に複数の光学素子１００を単に貼り付けるだけであるので、従来のトレーに比べて、面積当たりの収容量を多くすることができる。
また、光学素子１００の形状や大きさに対応した新規のトレーを適宜用意することなく、同一の粘着テープ１での梱包が可能となり効率的な生産対応が可能となる。
さらに、トレーを使用しないことから、トレーの形状に対応したトレー供給装置の段取り替えも不要となる。
また、図３に示すように真空引きをした場合には、荷崩れしづらくなるとともに光学素子１００に傷が付きにくくなる。
一方、図５のようにロール状の粘着テープ１及びロール状のエアーパッキン２をそのまま重ねて梱包した場合には、粘着テープ１やエアーパッキン２を断裁したり、真空引きする工程を行う必要がないので、より簡易に高効率で梱包することができる。 As described above, according to the present embodiment, the optical element 100 can be easily packed and the optical element 100 is securely attached to the adhesive tape 1 by simply attaching the plurality of optical elements 100 directly on the adhesive tape 1. Can be fixed on top.
Moreover, since the some optical element 100 is only affixed on the adhesive tape 1, the accommodation amount per area can be increased compared with the conventional tray.
Further, without preparing a new tray corresponding to the shape and size of the optical element 100 as appropriate, packaging with the same adhesive tape 1 is possible, and efficient production support is possible.
Furthermore, since no tray is used, it is not necessary to change the tray supply device corresponding to the shape of the tray.
In addition, when evacuation is performed as shown in FIG. 3, it is difficult for the cargo to collapse and the optical element 100 is less likely to be damaged.
On the other hand, when the roll-shaped adhesive tape 1 and the roll-shaped air packing 2 are stacked as they are as shown in FIG. 5, it is necessary to cut the adhesive tape 1 or the air packing 2 or perform a vacuuming process. Since there is no, it can pack more simply and with high efficiency.

なお、本発明は上記実施形態に限定されるものではなく、その要旨を逸脱しない範囲で適宜変更可能である。
例えば、光学素子１００の形状は、図１に示したものに限らず種々の形状の光学素子に変更可能である。 In addition, this invention is not limited to the said embodiment, In the range which does not deviate from the summary, it can change suitably.
For example, the shape of the optical element 100 is not limited to that shown in FIG. 1 and can be changed to optical elements having various shapes.
