Description

【０００１】
【発明の属する技術分野】
本発明は、ワークから例えばポリマ電池の外装材等の製品を成形するためのエンボス成形方法、およびそのエンボス成形装置に関する。
【０００２】
【従来の技術】
一般にポリマ電池は、外装材と、外装材内部に収納された電極材および電解質とを備えている。このうち外装材は電極材を収納するためのエンボス部を有し、エンボス部を有する外装材はワークをエンボス成形することにより得られる。
【０００３】
外装材を形成するワークは、アルミニウム層を一対のプラスチック層で挟持することにより構成され、エンボス部はエンボス成形装置により形成される。
【０００４】
【発明が解決しようとする課題】
上述のように、外装材はワークに対してエンボス成形装置によりエンボス成形を施すことにより得られる。エンボス成形装置は成形凸部を有する雄型と、成形凹部を有する雌型とからなり、ワークを雄型と雌型との間で挟持してエンボス成形を施す際、ワークは成形凸部により成形凹部内に引込まれる。
【０００５】
エンボス部を比較的深く成形するためには、成形凸部の高さおよび成形凹部の深さを大きくする必要があるが、この場合、ワークが雄型と雌型との間で堅く挟持されるためワークを成形凹部内に確実に引込むことがむずかしくなり、エンボス部を精度良く形成することができないことがある。
【０００６】
本発明はこのような点を考慮してなされたものであり、ワークに対して比較的深いエンボス部を容易かつ確実に成形することができるエンボス成形方法、およびそのエンボス成形装置を提供することを目的とする。
【０００７】
【課題を解決するための手段】
本発明は、複数のエンボス部を含む製品部を有するワークのうち製品部外周に対応して設けられビード跡を形成する雄型用ビードと、雄型用ビード内側に設けられたエンボス部に対応する成形凸部と、成形凸部と雄型用ビードとの間に設けられた雄型用押え部とを有する雄型と、雄型用ビードに対応する雌型用ビードと、成形凸部に対応する成形凹部と、雄型用押え部に対応する雌型用押え部とを有する雌型とを備え、ワークのうち雄型用押え部と雌型用押え部との間に対応する部分に切込みを形成するカッターを設け、これによりエンボス部を有するとともに切断されて包装材となる複数の製品部と、製品部から切離される製品部外周に位置するビード跡とを形成するとともに切込みは製品部とビード跡との間に位置し、ビード跡とともに製品部から切離されることを特徴とするエンボス成形装置である。
【０００８】
本発明は、複数のエンボス部を含む製品部を有するワークのうち製品部外周に対応して設けられビード跡を形成する雄型用ビードと、雄型用ビード内側に設けられたエンボス部に対応する成形凸部と、成形凸部と雄型用ビードとの間に設けられた雄型用押え部とを有する雄型と、雄型用ビードに対応する雌型用ビードと、成形凸部に対応する成形凹部と、雄型用押え部に対応する雌型用押え部とを有する雌型とを備えたエンボス成形装置を用いてワークに対してエンボス成形を施すエンボス成形方法であって、ワークのうち雄型用押え部と雌型用押え部との間に対応する部分にカッターを用いて予め切込みを形成する工程と、ワークに対して雄型と雌型との間でエンボス成形を施す工程と、を備え、これによりエンボス部を有するとともに切断されて包装材となる複数の製品部と、製品部から切離される製品部外周に位置するビード跡とを形成するとともに切込みは製品部とビード跡との間に位置し、ビード跡とともに製品部から切離されることを特徴とするエンボス成形方法である。
【０００９】
本発明によれば、予め切込みが形成されたワークに対して雄型と雌型との間でエンボス成形を施す。この場合、ワークの製品部外周は雄型用ビードと雌型用ビードとの間で挟持されるが、切込みは雄型用押え部と雌型用押え部との間に対応する部分に形成されているので、成形凸部により切込み内側のワークをスムースに成形凹部内に引込み、ワークにエンボス部を成形することができる。
【００１０】
【発明の実施の形態】
以下、図面を参照して本発明の実施の形態について説明する。
【００１１】
図１乃至図５は本発明の実施の形態を示す図である。
【００１２】
まず図４および図５により、ポリマ電池および包装材について説明する。
【００１３】
図４に示すように、ポリマ電池１はエンボス部７を有する包装材５と、包装材５のエンボス部７内に収納された電極材２と、エンボス部７内に充てんされた電解質４とを備え、電極材２から延びる一対のタブが包装材５から外方へ突出している。
【００１４】
包装材５のエンボス部７は予め形成され、エンボス部７内に電極材２と電解質４を収納し、この包装材５を折曲線６に沿って折曲げ、折曲げられた包装材５同志を接着することによりポリマ電池１が得られる。
【００１５】
また包装材５は、アルミ層５ａと、アルミ層５ａを挟持する基材層５ｂおよびヒートシール層５ｃとからなっている。このうち基材層５ｂはナイロンまたはＰＥＴからなっており、またヒートシール層５ｃはＰＰまたはＰＥからなっている。
【００１６】
なお包装材５のヒートシール層５ｃは、折曲線６に沿って包装材５を折曲げた場合に内側に位置して包装材５同志を接着するようになっている。
【００１７】
次に図１により、包装材５を作製するたのエンボス成形装置１０について説明する。まず包装材５を作製するためのワークＷについて説明する。ワークＷは上述した包装材５の層構成と同一の層構成を有しており、包装材５となる複数の製品部２０、２０を有している（図２）。
【００１８】
エンボス成形装置１０は雄型１５と、雄型１５との間でワークＷに対してエンボス成形を施す雌型１１とを備えている。
【００１９】
このうち雄型１５はワークＷのうち製品部２０、２０外周に対応して設けられた雄型用ビード１６と、雄型用ビード１６内側に設けられた雄型用押え部１７とからなり、雄型用押え部１７はワークＷを押圧する押圧面１７ａを有している。また雄型用押え部１７には、成形凸部１８が進退自在に設けられている。
【００２０】
一方、雌型１１は雄型用ビード１６に対応して設けられ雄型用ビード１６との間でワークＷを挟持する雌型用ビード１２と、雌型用ビード１２内側に雄型用押え部１７に対応して設けられた雌型用押え部１３とからなり、雌型用押え部１３は雄型用押え部１７の押圧面１７ａとの間でワークＷを押圧する押圧面１３ａを有している。
【００２１】
さらに、雌型１１は雄型１５の成形凸部１８が進入する成形凹部１４を有している。
【００２２】
次にエンボス成形装置１０を用いたエンボス成形方法について説明する。
【００２３】
まずアルミ層５ａを基材層５ｂとヒートシール層５ｃにより挟持してなるワークＷを準備する。
【００２４】
ワークＷは、包装材５となる複数の製品部２０、２０を有しており、各製品部２０、２０の間には後述のように雄型用ビード１６と雌型用ビード１２とによってビード跡２１が形成されるようになっている。
【００２５】
このようなワークＷの各製品部２０のうち、雄型用押え部１７と雌型用押え部１３との間に対応する部分に一対の切込み２２が形成される。この一対の切り込み２２は、雄型１５と雌型１１の外方（上側）において、カッター２５とカッター台２６により形成される。ここで雄型用押え部１７と雌型用押え部１３との間に対応する部分とは、各製品部２０のうちエンボス部７以外のすべての部分をいう。
【００２６】
なおカッター２５とカッター台２６を雄型１５と雌型１１の外方に設けることなく、カッター２５を雄型押え部１７に設けカッター台２６を雌型押え部１３に設けてもよい。
【００２７】
ワークＷはエンボス成形時に、成形凸部１８により成形凹部１４側へ引込まれるが、一対の切込み２２はこのワークＷの引込方向に直交する方向に形成されている。一対の切込み２２は成形凹部１４を越えて細長状に延びているが（図２）、この切込み２２をより細い円弧状に形成してもよい（図３）。
【００２８】
また図２および図３に示すように、一対の切込み２２をワークＷのビード跡２１と平行になるよう設けてもよいが、図６（ａ）に示すようにビード跡２１と直交するよう切り込み２２を設けてもよく、さらに図６（ｂ）に示すようにビード跡２１と平行する切込み２２と直交する切込み２２を両方設けてもよい。
【００２９】
ワークＷは、次に雄型１５と雌型１１との間に搬送され、次にワークＷに対して雄型１５と雌型１１が接近し、ワークＷが雄型１５の雄型用ビード１６と雌型１１の雌型用ビード１２との間で挟持され、また雄型用押え部１７と雌型用押え部１３の押圧面１７ａ，１３ａにより緩く押圧される。雄型用ビード１６と雌型用ビード１２は、各々表面に凹凸を有しており、ワークＷの製品部２０、２０間を堅固に挟持し、ワークＷの一つの製品部２０に対するエンボス成形装置１０によるエンボス成形加工が他の製品部２０に影響を及ぼさないようになっている。このためワークＷの一つの製品部２０に対してエンボス成形を施してエンボス部７を成形し、その後ワークＷの他の製品部２０に対してエンボス成形を施しても、すでに成形済の製品部２０のエンボス部７が変形したりすることはない。
【００３０】
このように雄型用ビード１６と雌型用ビード１２によりワークＷを挟持することにより、ワークＷの製品部２０、２０間にビード跡２１が形成される。
【００３１】
次に雄型１５の成形凸部１８が雌型１１の成形凹部１４内に進入し、このことによりワークＷが成形凹部１４内に引込まれてエンボス成形が行なわれ、ワークＷの製品部２０にエンボス部７が成形される。この場合、ワークＷの製品部２０は雄型用押え部１７と雌型用押え部１３の各々の押圧面１７ａ、１３ａにより緩やかに押圧される。またワークＷに一対の切込み２２が形成されているので、切込み２２より内側のワークＷは成形凹部１４内へスムースに引込まれる。すなわちワークＷは雄型用ビード１６と雌型用ビード１２との間で挟持されるが、切込み２２より内側のワークＷは雄型用ビード１６および雌型用ビード１２から比較的自由になっているため、移動が可能となる。
【００３２】
このためワークＷの製品部２０に対するエンボス成形を容易かつ精度良く行なうことができ、ワークＷに対してエンボス部７を精度良く形成することができる。
【００３３】
このようにして、ワークＷの各製品部２０にエンボス部７を成形した後、ワークＷは各製品部２０のうち一対の切込み２２内側で切断され、包装材５が作製される。
【００３４】
以上のように本実施の形態によれば、ワークＷの製品部２０に対してエンボス成形を精度良く行なうことができ、エンボス部７を精度良く形成することができる。
【００３５】
【発明の効果】
以上のように本発明によれば、ワークのうち雄型用押え部と雌型用押え部との間に対応する部分に予め切込みが形成されているので、切込み内側のワークをスムースに成形凹部へ引込むことができ、これによりワークにエンボス部を精度良く成形することができる。

Note that the cutter 25 may be provided in the male presser portion 17 and the cutter base 26 may be provided in the female presser portion 13 without providing the cutter 25 and the cutter base 26 outside the male die 15 and the female die 11.
[0027]
The workpiece W is drawn to the molding concave portion 14 side by the molding convex portion 18 at the time of emboss molding. The pair of cuts 22 extend in an elongated shape beyond the molding recess 14 (FIG. 2), but the cuts 22 may be formed in a narrower arc shape (FIG. 3).
[0028]
As shown in FIGS. 2 and 3, a pair of cuts 22 may be provided in parallel with the bead trace 21 of the workpiece W. However, as shown in FIG. 22 may be provided, and further, as shown in FIG. 6B, both of the notches 22 that are orthogonal to the notches 22 parallel to the bead marks 21 may be provided.
[0029]
Next, the workpiece W is transported between the male mold 15 and the female mold 11, and then the male mold 15 and the female mold 11 approach the workpiece W, and the workpiece W is the male mold bead 16 of the male mold 15. And the female bead 12 of the female mold 11, and are loosely pressed by the pressing surfaces 17 a and 13 a of the male pressing part 17 and the female pressing part 13. Each of the male bead 16 and the female bead 12 has irregularities on the surface thereof, and firmly holds the product parts 20 and 20 of the workpiece W so as to emboss the single product part 20 of the workpiece W. The embossing process by 10 does not affect the other product parts 20. For this reason, even if it emboss-molds with respect to one product part 20 of the workpiece | work W, the embossed part 7 is shape | molded, and emboss-molding is performed with respect to the other product part 20 of the workpiece | work W after that, already molded product part The 20 embossed portions 7 are not deformed.
[0030]
By sandwiching the workpiece W between the male bead 16 and the female bead 12 in this manner, a bead mark 21 is formed between the product parts 20 and 20 of the workpiece W.
[0031]
Next, the molding convex portion 18 of the male mold 15 enters the molding concave portion 14 of the female mold 11, whereby the workpiece W is drawn into the molding concave portion 14 and emboss molding is performed. The embossed part 7 is molded. In this case, the product portion 20 of the workpiece W is gently pressed by the pressing surfaces 17 a and 13 a of the male pressing portion 17 and the female pressing portion 13. Further, since the pair of cuts 22 are formed in the work W, the work W inside the cuts 22 is smoothly drawn into the molding recess 14. That is, the workpiece W is sandwiched between the male bead 16 and the female bead 12, but the workpiece W inside the notch 22 is relatively free from the male bead 16 and the female bead 12. Therefore, movement becomes possible.
[0032]
Therefore, the embossing of the workpiece W on the product portion 20 can be easily and accurately performed, and the embossed portion 7 can be accurately formed on the workpiece W.
[0033]
Thus, after forming the embossed part 7 in each product part 20 of the work W, the work W is cut inside the pair of cuts 22 in each product part 20 to produce the packaging material 5.
[0034]
As described above, according to the present embodiment, the embossing can be accurately performed on the product portion 20 of the workpiece W, and the embossed portion 7 can be formed with high accuracy.
[0035]
【The invention's effect】
As described above, according to the present invention, since the cut is formed in advance in a portion corresponding to the portion between the male presser portion and the female presser portion of the work, the concave portion inside the cut is smoothly formed. Thus, the embossed portion can be accurately formed on the workpiece.
