Description
本発明は、樹脂製薄板状基材の切断装置に関する。 The present invention relates to a cutting apparatus for a resinous thin plate-like substrate.
樹脂製の薄板状基材として、例えば、二次電池などの電気デバイスに用いられるセパレータ用のセパレータ基材がある。セパレータ基材は、ポリエチレン等の樹脂から形成され、非常に薄い長尺状の部材である。このセパレータ基材を切断することによって１つのセパレータとされる。セパレータ基材の切断は、加熱した刃によって切断する工法が知られている（例えば、特許文献１を参照）。 As a resin-made thin plate-like base material, for example, there is a separator base material for a separator used in an electric device such as a secondary battery. A separator base material is formed from resin, such as polyethylene, and is a very thin elongate member. By cutting the separator substrate, one separator is obtained. A method of cutting the separator base material with a heated blade is known (see, for example, Patent Document 1).
ところで、加熱した刃は、刃の表面のうち刃先などの切断に寄与する部分において樹脂製のセパレータ基材と接触してセパレータ基材を切断する。切断時において、刃の表面のうち切断に寄与しない部分がセパレータ基材と接触し、セパレータ基材のうち切断箇所以外の部分が溶融することがある。このため、セパレータの切断形状・寸法に関わる品質は低下する。また、加熱した刃の表面のうち切断に寄与する部分だけでなく切断に寄与しない部分にも樹脂が固着すると、切断性が悪くなる虞があるため、刃を清掃する必要が生じる。このため、刃の表面に多くの樹脂が固着すると、切断性が悪化し、刃の工具寿命が短くなる要因になる。 By the way, the heated blade contacts the resin separator substrate at the portion of the blade surface that contributes to cutting, such as the blade tip, and cuts the separator substrate. At the time of cutting, a portion of the blade surface that does not contribute to cutting may come into contact with the separator base material, and a portion other than the cutting portion of the separator base material may melt. For this reason, the quality related to the cutting shape and dimensions of the separator is lowered. Further, if the resin adheres not only to the portion that contributes to cutting but also to the portion that does not contribute to cutting on the surface of the heated blade, the cutting performance may be deteriorated, and thus the blade needs to be cleaned. For this reason, when a large amount of resin adheres to the surface of the blade, the cutting performance is deteriorated, and the tool life of the blade is shortened.
本発明は、上記従来技術に伴う課題を解決するためになされたものであり、樹脂製のセパレータ基材を加熱した刃で切断した際、刃に固着する樹脂を低減して切断性の悪化を遅らせ、刃の工具寿命を延ばすことができ、かつセパレータの切断形状、寸法などに関わる品質の低下を抑制することが可能な樹脂製薄板状基材の切断装置を提供することを目的とする。 The present invention was made in order to solve the problems associated with the above-described prior art, and when cutting a resin separator base with a heated blade, the resin adhering to the blade is reduced to reduce the cutting performance. An object of the present invention is to provide a cutting device for a resinous thin plate-like substrate which can be delayed, extend the tool life of the blade, and can suppress deterioration in quality related to the cutting shape and dimensions of the separator.
上記目的を達成する本発明に係る樹脂製薄板状基材の切断装置は、樹脂製の薄板状基材を切断する刃が設けられる切断部と、前記刃を加熱する加熱部材が配置される基部と、を備える切断部材を有している。切断装置は、さらに前記加熱部材で生じた熱が前記薄板状基材に伝わることを抑制する断熱部材を有している。前記断熱部材は、前記切断部材の表面のうち前記切断に寄与しない部分であって、かつ前記薄板状基材に接触する部分に少なくとも設けられる。 The apparatus for cutting a resinous thin-plate base material according to the present invention that achieves the above object includes a cutting portion provided with a blade for cutting the resin-made thin plate-like base material, and a base portion on which a heating member for heating the blade is disposed. And a cutting member. The cutting device further includes a heat insulating member that suppresses heat generated by the heating member from being transmitted to the thin plate-like substrate. The heat insulating member is provided at least on a portion of the surface of the cutting member that does not contribute to the cutting and that contacts the thin plate-like substrate.
上記のように構成した本発明の樹脂製薄板状基材の切断装置によれば、切断部材の表面のうち切断に寄与しない部分であって、かつ薄板状基材に接触する部分には、断熱部材が設けられる。このため、加熱した切断部材の表面のうち当該部分は、断熱部材を介して薄板状基材と接触するので、薄板状基材の当該接触部分を溶融することはない。したがって、切断部材に断熱部材を設けることにより、切断部材に固着する樹脂を低減できるので、切断性の悪化を遅らせることができ、切断部材の工具寿命を延ばすことができる。また、切断部材に断熱部材を設けることにより、薄板状基材の切断箇所以外の部分を溶融しないため、切断形状、寸法などに関わる品質の低下を抑制することができる。 According to the resin thin plate-like substrate cutting device of the present invention configured as described above, the portion of the surface of the cutting member that does not contribute to cutting and is in contact with the thin plate-like substrate is insulated. A member is provided. For this reason, since the said part contacts the thin plate-shaped base material through the heat insulation member among the surfaces of the heated cutting member, the said contact part of a thin plate-shaped base material is not fuse | melted. Therefore, since the resin fixed to the cutting member can be reduced by providing the heat insulating member on the cutting member, the deterioration of the cutting property can be delayed and the tool life of the cutting member can be extended. Further, by providing the heat insulating member on the cutting member, the portion other than the cut portion of the thin plate-like base material is not melted, so that it is possible to suppress deterioration in quality related to the cutting shape and dimensions.

以下、添付した図面を参照しながら、本願発明に係る実施形態を説明する。図面における各部材の大きさや比率は、説明の都合上誇張され実際の大きさや比率とは異なる場合がある。なお、薄板状基材として、たとえば、電気デバイスとしての二次電池に用いられるセパレータ用の基材を例に挙げる。
<Embodiment>
Embodiments according to the present invention will be described below with reference to the accompanying drawings. The size and ratio of each member in the drawings are exaggerated for convenience of explanation and may be different from the actual size and ratio. In addition, as a thin plate-shaped base material, the base material for separators used for the secondary battery as an electrical device is mentioned as an example, for example.
本実施形態に係る樹脂製のセパレータ基材６０（薄板状基材に相当）の切断装置１００を組み込んだ加工機１０、およびセパレータ基材６０の切断装置１００について、図１〜図５を参照しながら説明する。 The processing machine 10 incorporating the cutting device 100 for a resin separator base 60 (corresponding to a thin plate-like base) according to the present embodiment and the cutting device 100 for the separator base 60 are described with reference to FIGS. While explaining.
まず、セパレータ基材６０の切断装置１００を備えた加工機１０の構成、加工機１０が形成する二次電池に採用されている袋詰電極５０について、図１および図２を参照しながら説明する。 First, the structure of the processing machine 10 provided with the cutting device 100 for the separator base 60 and the packaged electrode 50 employed in the secondary battery formed by the processing machine 10 will be described with reference to FIGS. 1 and 2. .
図１は、実施形態に係るセパレータ基材６０の切断装置１００を組み込んだ加工機１０を示す模式図である。図２（Ａ）は、袋詰電極５０の一例を示す図、図２（Ｂ）は、電極７０および一対のセパレータ６１、６１を搬送しながら搬送方向の前端側から順次重ねる様子を模式的に示す斜視図である。 Drawing 1 is a mimetic diagram showing processing machine 10 incorporating cutting device 100 of separator base material 60 concerning an embodiment. FIG. 2A is a diagram showing an example of the packaged electrode 50, and FIG. 2B schematically shows a state in which the electrode 70 and the pair of separators 61 and 61 are sequentially stacked from the front end side in the transport direction. It is a perspective view shown.
加工機１０は、電極７０の両面に一対のセパレータ６１、６１を積層して袋詰電極５０を形成する。加工機１０に組み込んだ切断装置１００によって、長尺のセパレータ基材６０を一定間隔で切断することによって、個々のセパレータ６１を形成する。なお、図１および図２（Ａ）（Ｂ）に示される矢印ａは、袋詰電極５０を製造するときに電極７０および一対のセパレータ６１、６１を搬送する搬送方向を示している。図１および図２（Ａ）（Ｂ）において図中右側が搬送方向の下流側であり、各部材における「前」といい、図中左側が搬送方向の上流側であり、各部材における「後」という。また、搬送方向と交差する方向に位置するセパレータの縁を「側方縁」といい、搬送方向に位置するセパレータの縁を「前方縁」「後方縁」という。一対のセパレータ６１、６１の間に電極７０が挟まれた積層体であって、セパレータ６１、６１同士の接合が終了する前の積層体を「ワークＷ」という。 The processing machine 10 forms a packaged electrode 50 by laminating a pair of separators 61, 61 on both surfaces of the electrode 70. The individual separators 61 are formed by cutting the long separator substrate 60 at regular intervals by the cutting device 100 incorporated in the processing machine 10. 1 and FIGS. 2A and 2B indicate the conveyance direction in which the electrode 70 and the pair of separators 61 and 61 are conveyed when the packaged electrode 50 is manufactured. In FIGS. 1 and 2A and 2B, the right side in the drawing is the downstream side in the transport direction and is referred to as “front” in each member, and the left side in the drawing is the upstream side in the transport direction. " Further, the edge of the separator located in the direction intersecting the transport direction is referred to as “side edge”, and the edge of the separator located in the transport direction is referred to as “front edge” or “rear edge”. A laminated body in which the electrode 70 is sandwiched between the pair of separators 61 and 61 and before the separators 61 and 61 are joined together is referred to as “work W”.
図２（Ａ）（Ｂ）を参照して、袋詰電極５０は、正極または負極の電極７０を一対のセパレータ６１、６１によって袋状に包装している。本実施形態にあっては、正極を袋詰電極５０としている。電極７０は、金属箔の両面に活物質を塗布した本体部７１と、金属箔の一部から形成される他の部材と電気的に接続するタブ７２と、を備えている。セパレータ基材６０は、樹脂材料からなる薄膜であり、電極７０の本体部７１よりもやや大きい大きさを有している。電極７０の本体部７１のみを一対のセパレータ６１、６１によって挟み込み、電極７０のタブ７２を外部に臨ませている。重ねられた一対のセパレータ６１、６１の側方縁６２同士を接合している。また、重ねられた一対のセパレータ６１、６１の前方縁６３または後方縁６４の少なくとも一方の縁同士を接合している。図２（Ａ）に示す例では、重ねられた一対のセパレータ６１、６１の後方縁６４同士を接合している。 Referring to FIGS. 2A and 2B, the packaged electrode 50 is formed by packaging a positive electrode or a negative electrode 70 in a bag shape with a pair of separators 61 and 61. In the present embodiment, the positive electrode is the packaged electrode 50. The electrode 70 includes a main body 71 in which an active material is applied to both surfaces of a metal foil, and a tab 72 that is electrically connected to another member formed from a part of the metal foil. The separator base material 60 is a thin film made of a resin material, and has a size slightly larger than the main body portion 71 of the electrode 70. Only the main body 71 of the electrode 70 is sandwiched between the pair of separators 61, 61, and the tab 72 of the electrode 70 is exposed to the outside. The side edges 62 of the pair of separators 61 and 61 are joined to each other. Further, at least one edge of the front edge 63 or the rear edge 64 of the pair of separators 61 and 61 that are overlapped is joined. In the example shown in FIG. 2A, the rear edges 64 of the pair of separators 61, 61 that are overlapped are joined together.
図２（Ａ）（Ｂ）を参照して、セパレータ６１、６１同士を接合する「前端６５」は、重ね合されたセパレータ６１、６１のいわゆる口開きを抑える観点から自由に設定することができ、たとえば、電極７０の本体部７１に揃う位置や、文字どおりのセパレータ６１の角部のほか、活物質の塗布ラインに揃う位置であってもよい。 2A and 2B, the “front end 65” for joining the separators 61 and 61 can be freely set from the viewpoint of suppressing the so-called opening of the separators 61 and 61 that are overlapped. For example, it may be a position aligned with the body portion 71 of the electrode 70, a literal corner portion of the separator 61, or a position aligned with the active material application line.
図１を参照して、加工機１０は、概説すると、搬送部２０と、第１の接合部３０と、第２の接合部４０とを有している。搬送部２０は、電極７０および一対のセパレータ６１、６１を搬送しながら搬送方向の前端６５側から順次重ねる。第１の接合部３０は、一対のセパレータ６１、６１の側方縁６２同士を接合する。第２の接合部４０は、一対のセパレータ６１、６１の前方縁６３または後方縁６４の少なくとも一方の縁同士を接合する。そして、搬送部２０によって搬送されながら順次重なる一対のセパレータ６１、６１の側方縁６２同士を搬送方向の前端６５側から第１の接合部３０によって順次接合する。さらに、搬送部２０による搬送を停止した状態で一対のセパレータ６１、６１の前方縁６３または後方縁６４の少なくとも一方の縁同士を第２の接合部４０によって接合する。図示例では、第２の接合部４０は、一対のセパレータ６１、６１の後方縁６４同士を接合している。側方縁６２での接合点６６はたとえば５点、後方縁６４での接合点６６はたとえば４点である。この加工機１０に、長尺のセパレータ基材６０を一定間隔で切断する切断装置１００を組み込んでいる。 With reference to FIG. 1, the processing machine 10 generally includes a conveyance unit 20, a first bonding unit 30, and a second bonding unit 40. The conveyance unit 20 sequentially stacks the electrode 70 and the pair of separators 61 and 61 from the front end 65 side in the conveyance direction while conveying the electrode 70 and the pair of separators 61 and 61. The first joint 30 joins the side edges 62 of the pair of separators 61 and 61. The second joint 40 joins at least one of the front edge 63 or the rear edge 64 of the pair of separators 61, 61. Then, the side edges 62 of the pair of separators 61 and 61 that are sequentially overlapped while being transported by the transport unit 20 are sequentially joined by the first joining unit 30 from the front end 65 side in the transport direction. Further, at least one edge of the front edge 63 or the rear edge 64 of the pair of separators 61, 61 is joined by the second joining part 40 in a state where the transportation by the transportation unit 20 is stopped. In the illustrated example, the second joint portion 40 joins the rear edges 64 of the pair of separators 61 and 61. The junction point 66 at the side edge 62 is, for example, five points, and the junction point 66 at the rear edge 64 is, for example, four points. The processing machine 10 incorporates a cutting device 100 that cuts the long separator substrate 60 at regular intervals.
搬送部２０は、一対のセパレータ６１、６１のそれぞれを保持して搬送する一対の搬送部材２２の上流側に配置された電極搬入部２１と、一対の搬送部材２２の下流側に配置された複数個の下流側搬送部２３、２４と、を含んでいる。一対の搬送部材２２の間に、ワークＷを挟持するニップ部Ｎを形成している。ニップ部Ｎの隙間寸法は、ワークＷの厚さによって適宜調整される。電極搬入部２１は、所定形状に形成された電極７０をニップ部Ｎに接線方向に沿って送り込む。下流側搬送部２３、２４は、重ねられた電極７０および一対のセパレータ６１、６１を搬送するために複数設けられている。図示例では２個の下流側搬送部２３、２４を設けて、下流側搬送部２３、２４同士の間に第２の接合部４０を配置してある。 The transport unit 20 includes an electrode carry-in unit 21 disposed on the upstream side of the pair of transport members 22 that holds and transports the pair of separators 61, 61, and a plurality of transport units disposed on the downstream side of the pair of transport members 22. The downstream conveyance parts 23 and 24 are included. A nip portion N that sandwiches the workpiece W is formed between the pair of conveying members 22. The gap size of the nip portion N is appropriately adjusted according to the thickness of the workpiece W. The electrode carrying-in part 21 feeds the electrode 70 formed in a predetermined shape into the nip part N along the tangential direction. A plurality of downstream transport units 23 and 24 are provided to transport the stacked electrode 70 and the pair of separators 61 and 61. In the illustrated example, two downstream transport units 23 and 24 are provided, and the second joint unit 40 is disposed between the downstream transport units 23 and 24.
電極搬入部２１は、たとえば、電極７０を吸着して搬送自在な吸着装置２５と、吸着装置２５によって搬送されてきた電極７０を支持する支持ローラ２６と、電極７０をニップ部Ｎに接線方向に沿って送り込む一対の搬入ローラ２７とを有している。吸着装置２５は、垂直に下降して電極７０を吸着し、電極７０の略水平状態を維持したまま上昇した後、搬送方向の下流側に移動する。搬入ローラ２７のそれぞれは、吸着装置２５によって搬送された電極７０に対して接近離反移動自在に設けられ、電極７０を挟み込んで回転することによって電極７０をニップ部Ｎに接線方向に沿って送り込む。なお、吸着装置２５によって吸着する電極７０の位置が、搬送方向にずれていたり、搬送方向に対して斜めにずれていたりする場合がある。電極搬入部２１では、吸着装置２５によって電極７０を吸着する前に、これから吸着搬送しようとする電極７０の位置ずれをセンサカメラによって予め検出している。吸着装置２５は、電極７０を吸着した後、電極７０の姿勢を適正な姿勢に修正しながら移動する。これによって、電極７０を、適正な姿勢の状態において、ニップ部Ｎに搬送する。 The electrode carrying-in unit 21 includes, for example, an adsorbing device 25 that can adsorb and convey the electrode 70, a support roller 26 that supports the electrode 70 conveyed by the adsorbing device 25, and the electrode 70 tangentially to the nip N. It has a pair of carrying-in roller 27 sent along. The adsorption device 25 descends vertically to adsorb the electrode 70, moves up while maintaining the substantially horizontal state of the electrode 70, and then moves downstream in the transport direction. Each of the carry-in rollers 27 is provided so as to be movable toward and away from the electrode 70 conveyed by the suction device 25, and feeds the electrode 70 into the nip portion N along the tangential direction by sandwiching and rotating the electrode 70. Note that the position of the electrode 70 that is attracted by the suction device 25 may be shifted in the transport direction or may be shifted obliquely with respect to the transport direction. In the electrode carry-in unit 21, before the electrode 70 is adsorbed by the adsorbing device 25, a positional deviation of the electrode 70 to be adsorbed and conveyed is detected in advance by a sensor camera. After attracting the electrode 70, the suction device 25 moves while correcting the posture of the electrode 70 to an appropriate posture. Thus, the electrode 70 is conveyed to the nip portion N in a proper posture state.
一対の搬送部材２２は、図１に示すように、たとえば円柱形状のドラムである。一対の搬送部材２２は、搬送方向に直交しながら、所定の隙間を隔てて、回転軸が互いに平行に対向する態様で配置されている。一対の搬送部材２２のそれぞれは、周面が、セパレータ６１を保持する保持面２２ａとなっている。一対の搬送部材２２は、所定形状に形成されたセパレータ６１を保持面２２ａ上に保持しながら搬送する。 As shown in FIG. 1, the pair of conveying members 22 are, for example, cylindrical drums. The pair of transport members 22 are arranged in such a manner that the rotation shafts face each other in parallel with a predetermined gap therebetween while being orthogonal to the transport direction. Each of the pair of transport members 22 has a holding surface 22 a that holds the separator 61 on the peripheral surface. The pair of conveying members 22 conveys the separator 61 formed in a predetermined shape while holding it on the holding surface 22a.
一対の搬送部材２２のそれぞれの保持面２２ａにセパレータ６１を保持する手段については特に限定されないが、吸引吸着あるいは静電吸着などを適用することができる。たとえば、吸引吸着式にあっては、保持面２２ａは、複数の空気吸引孔を有している。これら空気吸引孔から空気を吸引することによって、セパレータ６１を保持面２２ａに保持する。 The means for holding the separator 61 on each holding surface 22a of the pair of conveying members 22 is not particularly limited, and suction adsorption or electrostatic adsorption can be applied. For example, in the suction adsorption type, the holding surface 22a has a plurality of air suction holes. By sucking air from these air suction holes, the separator 61 is held on the holding surface 22a.
一対の搬送部材２２は、ニップ部Ｎにおいて搬送方向の前方に向けて同方向に回転する。すなわち、上側の搬送部材２２は、図１において反時計回り方向に回転することによって、保持面２２ａに貼り付けられたセパレータ６１をニップ部Ｎに向けて搬送する。下側の搬送部材２２は、時計回り方向に回転することによって、保持面２２ａに貼り付けられたセパレータ６１をニップ部Ｎに向けて搬送する。一対の搬送部材２２は、回転軸に接続された図示しない駆動モータによって、同期して回転駆動される。制御部材２００（図３参照）が、駆動モータの回転制御を行う。 The pair of transport members 22 rotate in the same direction toward the front in the transport direction at the nip portion N. That is, the upper conveying member 22 conveys the separator 61 attached to the holding surface 22a toward the nip portion N by rotating counterclockwise in FIG. The lower conveyance member 22 conveys the separator 61 attached to the holding surface 22a toward the nip portion N by rotating in the clockwise direction. The pair of transport members 22 are rotationally driven in synchronization by a drive motor (not shown) connected to the rotation shaft. The control member 200 (see FIG. 3) controls the rotation of the drive motor.
電極搬入部２１が、一対の搬送部材２２の回転と同期して、電極７０を略水平状態に搬送してニップ部Ｎに接線方向に沿って送り込む。一方、一対の搬送部材２２が、それぞれの保持面２２ａに貼り付けたセパレータ６１を回転にしたがってニップ部Ｎに送り込む。これにより、搬送部２０は、電極７０および一対のセパレータ６１、６１を搬送しながら搬送方向の前端６５側から順次重ねて積層することができる。 The electrode carry-in portion 21 conveys the electrode 70 in a substantially horizontal state in synchronization with the rotation of the pair of conveying members 22 and feeds the electrode 70 into the nip portion N along the tangential direction. On the other hand, the pair of transport members 22 feeds the separators 61 attached to the respective holding surfaces 22a into the nip portion N according to the rotation. Thereby, the conveyance part 20 can be laminated | stacked sequentially from the front end 65 side of a conveyance direction, conveying the electrode 70 and a pair of separators 61 and 61 sequentially.
セパレータ基材６０は、図示しないセパレータロールから順次繰り出されてくる長尺の薄板状基材である。セパレータ基材６０は、たとえば、溶融材６７と耐熱材６８とを積層して形成する（図３参照）。耐熱材６８は、溶融材６７よりも溶解温度が高い。セパレータ基材６０の溶融材６７の材料には、たとえば、ポリエチレンまたはポリプロピレンのポリオレフィン系微多孔質から構成される材料を用いている。溶融材６７には、非水溶媒に電解質を溶解することによって調製した非水電解液を含浸させている。非水電解液を保持するために、ポリマーを含有させている。セパレータ基材６０の耐熱材６８の材料は、たとえば、無機化合物を高温で成形したセラミックスを用いている。具体的には、セラミックスは、シリカ（ＳｉＯ２）、アルミナ、ジルコニウム酸化物、チタン酸化物等のセラミック粒子とバインダーの結合により形成される多孔質からなる。耐熱材６８の材料は、セラミックスに限定されることはなく、溶融材６７よりも溶解温度が高ければよい。 The separator substrate 60 is a long thin plate-like substrate that is sequentially drawn from a separator roll (not shown). Separator base material 60 is formed, for example, by laminating molten material 67 and heat-resistant material 68 (see FIG. 3). The heat-resistant material 68 has a melting temperature higher than that of the melting material 67. As the material of the melting material 67 of the separator base 60, for example, a material composed of polyolefin microporous material of polyethylene or polypropylene is used. The molten material 67 is impregnated with a nonaqueous electrolytic solution prepared by dissolving an electrolyte in a nonaqueous solvent. In order to hold the non-aqueous electrolyte, a polymer is included. As the material of the heat-resistant material 68 of the separator substrate 60, for example, ceramics formed by molding an inorganic compound at a high temperature is used. Specifically, the ceramic is made of a porous material formed by bonding ceramic particles such as silica (SiO 2 ), alumina, zirconium oxide, titanium oxide and the like and a binder. The material of the heat-resistant material 68 is not limited to ceramics, and it is sufficient that the melting temperature is higher than that of the melting material 67.
セパレータ基材６０の搬送路には、セパレータ基材６０を挟持する図示しないタイミングローラが配置されている。制御部材２００が、タイミングローラの作動を制御し、セパレータ基材６０を搬送部材２２に送り出すタイミングの制御を行う。セパレータ基材６０を切断するために、電極７０の搬送路の上方および下方のそれぞれに、セパレータ基材６０の切断装置１００を設けている。図示しない上記タイミングローラがセパレータ基材６０を送り出すと、セパレータ基材６０が搬送部材２２の保持面２２ａに吸引されながら搬送される。セパレータ基材６０が所定位置まで搬送されたタイミングでそれぞれの切断装置１００を作動させることによって、セパレータ基材６０を所定間隔で切断し、セパレータ６１を形成する。 A timing roller (not shown) that sandwiches the separator substrate 60 is disposed in the conveyance path of the separator substrate 60. The control member 200 controls the operation of the timing roller and controls the timing at which the separator substrate 60 is sent to the transport member 22. In order to cut the separator base 60, the separator base 60 cutting device 100 is provided above and below the transport path of the electrode 70. When the timing roller (not shown) feeds the separator base 60, the separator base 60 is transported while being sucked by the holding surface 22 a of the transport member 22. By operating each cutting device 100 at the timing when the separator base material 60 is conveyed to a predetermined position, the separator base material 60 is cut at a predetermined interval to form the separator 61.
下流側搬送部２３は、たとえば、一対の搬送部材２２のニップ部Ｎから送り出されるワークＷを載置して搬送する第１のコンベアである。下流側搬送部２４は、たとえば、第１のコンベアである下流側搬送部２３の下流側に配置されセパレータ６１の側方縁６２同士の接合が終了したワークＷを載置して搬送する第２のコンベアである。下流側搬送部２３と下流側搬送部２４との間に第２の接合部４０が配置されている。セパレータ６１の後方縁６４同士を第２の接合部４０によって接合した後においては、下流側搬送部２４は、製造された袋詰電極５０を、次工程の処理を行うステージに向けて搬送する。下流側搬送部２３、２４は、たとえば吸着コンベアから構成することができる。下流側搬送部２３、２４の幅は、セパレータ６１の幅よりも狭い寸法を有し、第１の接合部３０の往復移動と干渉しないようにしている。下流側搬送部２３、２４は、ローラに接続された図示しないコンベア用駆動モータによって、ワークＷの搬送に同期して回転駆動される。制御部材２００が、コンベア用駆動モータの回転制御を行う。なお、下流側搬送部２３、２４としてコンベアを使用しているが、吸着ハンドなど他の搬送装置を使用してもよい。 The downstream transport unit 23 is, for example, a first conveyor that places and transports the workpiece W fed from the nip N of the pair of transport members 22. The downstream transport unit 24 is, for example, a second conveyor that is placed on the downstream side of the downstream transport unit 23, which is the first conveyor, and places and transports the workpiece W in which the side edges 62 of the separator 61 are joined. It is a conveyor. A second joint 40 is disposed between the downstream transport unit 23 and the downstream transport unit 24. After the rear edges 64 of the separator 61 are joined to each other by the second joining portion 40, the downstream transport portion 24 transports the manufactured packed electrode 50 toward the stage that performs the next process. The downstream side conveyance parts 23 and 24 can be comprised, for example from a suction conveyor. The widths of the downstream transport units 23 and 24 are smaller than the width of the separator 61 so that they do not interfere with the reciprocating movement of the first joining unit 30. The downstream conveyance units 23 and 24 are rotationally driven in synchronization with the conveyance of the workpiece W by a conveyor drive motor (not shown) connected to the rollers. The control member 200 controls the rotation of the conveyor drive motor. In addition, although the conveyor is used as the downstream conveyance parts 23 and 24, you may use other conveying apparatuses, such as a suction hand.
第１の接合部３０は、重ねられた電極７０および一対のセパレータ６１、６１を搬送する搬送路、つまりワークＷの搬送路を挟んで向かい合って、上下に一対設けてある。第２の接合部４０も、ワークＷの搬送路を挟んで向かい合って、上下に一対設けてある。対をなすセパレータ基材６０の両面のそれぞれから接合することになるので、片面のみから接合する場合に比べて、均一な接合状態を作り出すことができる。また、セパレータ基材６０の材質、特に、熱的な性質が異なるセパレータ基材６０を適用する場合に、接合条件の最適化のための調整が容易となる。 A pair of the first joint portions 30 are provided on the upper and lower sides so as to face each other across the conveyance path for conveying the stacked electrode 70 and the pair of separators 61, 61, that is, the conveyance path for the workpiece W. A pair of second joining portions 40 are also provided on the upper and lower sides facing each other across the conveyance path of the workpiece W. Since it joins from each of both surfaces of the separator base material 60 which makes a pair, compared with the case where it joins from only one side, a uniform joining state can be created. In addition, when the separator base material 60, particularly the separator base material 60 having different thermal properties, is applied, adjustment for optimizing the joining conditions is facilitated.
第１と第２の接合部３０、４０において、重ねられた一対のセパレータ６１、６１の縁同士を接合する手段については特に限定されず、熱溶着、圧着、接着または溶接のいずれかの手段を適用することができる。本実施形態にあっては、接合は、熱溶着により行っている。樹脂製のセパレータ６１、６１同士を簡単に接合することができるからである。 In the first and second joint portions 30 and 40, the means for joining the edges of the pair of separators 61 and 61 overlapped is not particularly limited, and any means of heat welding, pressure bonding, adhesion, or welding is used. Can be applied. In this embodiment, joining is performed by heat welding. This is because the resin separators 61 and 61 can be easily joined together.
つぎに、セパレータ基材６０の切断装置１００の構成について、図３および図４を参照しながら説明する。 Next, the configuration of the separator substrate 60 cutting apparatus 100 will be described with reference to FIGS. 3 and 4.
図３は、実施形態に係る樹脂製のセパレータ基材６０の切断装置１００の構成を示す断面図である。図４は、実施形態に係る樹脂製のセパレータ基材６０の切断装置１００の構成を示す斜視図である。 FIG. 3 is a cross-sectional view illustrating a configuration of the cutting device 100 for the resin separator base 60 according to the embodiment.

And a cutting member 110 having 130. The cutting device 100 further includes a heat insulating member 140 that suppresses heat generated by the heating member 131 from being transmitted to the separator base material 60. The heat insulating member 140 is provided at least on a portion of the surface of the cutting member 110 that does not contribute to cutting and that contacts the separator substrate 60 (heat insulating required portion 121c). Furthermore, the cutting device 100 has a mounting member 170 for mounting the separator base material 60. The placement member 170 corresponds to the conveyance member 22 in the processing machine 10. Further, the holding surface 22 a of the conveying member 22 corresponds to the mounting surface 170 a of the mounting member 170. This will be described in detail below.
切断部材１１０は、載置面１７０ａ上に載置されたセパレータ基材６０を、セパレータ基材６０の搬送方向と交差する方向に切断する。切断部材１１０は、載置部材１７０に対し接近離反移動可能（図中では上下動可能）な構成となっている。さらに詳しくは、切断部材１１０は、セパレータ基材６０を切断するための刃１２１を載置部材１７０に向かい合う方向に移動または載置部材１７０から離れる方向に移動（図中では上下動）するための駆動源１５０をも有する。駆動源１５０は、たとえば油圧シリンダーから構成され、作動ロッド１５１の先端に基部１３０を介して切断部１２０を取り付けている。切断部１２０は、基部１３０と接して配置している。 The cutting member 110 cuts the separator base material 60 placed on the placement surface 170 a in a direction that intersects the transport direction of the separator base material 60. The cutting member 110 is configured to be movable toward and away from the mounting member 170 (movable up and down in the drawing). More specifically, the cutting member 110 moves the blade 121 for cutting the separator base material 60 in a direction facing the mounting member 170 or in a direction away from the mounting member 170 (up and down movement in the drawing). A drive source 150 is also included. The drive source 150 is composed of, for example, a hydraulic cylinder, and the cutting portion 120 is attached to the tip of the operating rod 151 via the base portion 130. The cutting part 120 is disposed in contact with the base part 130.
切断部１２０の刃１２１は、図４に示すように、直線状の鋭利な刃から成る。セパレータ基材６０の搬送方向と交差する方向に沿って配置される。刃１２１は、長尺状のセパレータ基材６０を一定の幅で切断する。刃１２１の長手方向の幅は、セパレータ基材６０の搬送方向と交差する方向の幅よりも長い。刃１２１の材料は、たとえば銅と亜鉛の合金である黄銅からなる。黄銅は、特に、銅の比率が約７０％であって亜鉛の比率が約３０％であるＣ２８０１を用いている。刃１２１の材料は、黄銅Ｃ２８０１に限定されることはなく、熱伝導率の高い材料であればよい。刃１２１は、先端部分の刃先１２１ａをセパレータ基材６０に接触することにより、セパレータ基材６０を切断する。なお、載置部材１７０の載置面１７０ａには、切断部１２０の刃１２１の刃先１２１ａを受けるための凹部１２１ｂが形成されている。 As shown in FIG. 4, the blade 121 of the cutting unit 120 is a straight, sharp blade. It arrange | positions along the direction which cross | intersects the conveyance direction of the separator base material 60. FIG. The blade 121 cuts the long separator base 60 with a certain width. The width in the longitudinal direction of the blade 121 is longer than the width in the direction intersecting the transport direction of the separator substrate 60. The material of the blade 121 is made of brass which is an alloy of copper and zinc, for example. For brass, in particular, C2801 having a copper ratio of about 70% and a zinc ratio of about 30% is used. The material of the blade 121 is not limited to brass C2801, and any material having high thermal conductivity may be used. The blade 121 cuts the separator substrate 60 by bringing the blade edge 121 a at the tip portion into contact with the separator substrate 60. The mounting surface 170a of the mounting member 170 is formed with a recess 121b for receiving the cutting edge 121a of the blade 121 of the cutting unit 120.
基部１３０は、内部に加熱部材１３１を配置し、かつ切断部１２０に接続しており、加熱部材１３１で生じた熱を切断部１２０に伝導するために用いられる。基部１３０は、駆動源１５０と接続しており、作動ロッド１５１の作動に基づき切断部１２０とともに載置部材１７０に向かう方向へ接近または離反する。基部１３０の材料は、たとえば、黄銅Ｃ２６００を用いている。基部１３０の材料は、黄銅Ｃ２６００に限定されることはなく、熱伝導率の高い材料であればよい。 The base part 130 has the heating member 131 disposed therein and is connected to the cutting part 120, and is used to conduct heat generated by the heating member 131 to the cutting part 120. The base portion 130 is connected to the drive source 150 and approaches or separates in the direction toward the mounting member 170 together with the cutting portion 120 based on the operation of the operation rod 151. For example, brass C2600 is used as the material of the base 130. The material of the base 130 is not limited to brass C2600, and any material having high thermal conductivity may be used.
加熱部材１３１は、切断部１２０を加熱するために配置されている。加熱部材１３１は、基部１３０の内部に配置され、発した熱を基部１３０を介して切断部１２０に伝導する。加熱部材１３１は、たとえば電気ヒーター赤外線ヒーター、高周波コイルなどのように、瞬間的かつ均等に切断部１２０を加熱可能なものから構成されている。 The heating member 131 is disposed to heat the cutting part 120. The heating member 131 is disposed inside the base portion 130 and conducts the generated heat to the cutting portion 120 through the base portion 130. The heating member 131 is composed of a member capable of heating the cutting part 120 instantaneously and evenly, such as an electric heater infrared heater, a high-frequency coil, or the like.
断熱部材１４０は、前述したように、切断部材１１０の表面のうち切断に寄与しない部分であって、かつセパレータ基材６０に接触する部分（断熱必要部分１２１ｃ）に少なくとも設けられる。 As described above, the heat insulating member 140 is provided at least on a portion of the surface of the cutting member 110 that does not contribute to cutting and that contacts the separator substrate 60 (heat insulating necessary portion 121c).
切断部材１１０のうち切断に寄与する部分とは、セパレータ基材６０を切断中に切断箇所に接触する部分であり、刃先１２１ａを指す。刃先１２１ａは、刃１２１のうち刃の先端１２１ｂから所定の長さＴの部分である。この所定の長さＴは、載置部材１７０の凹部１７０ｂのサイズや刃１２１の形状に合わせて設定されるので、一意の値に定まるものではない。したがって、切断部材１１０のうち切断に寄与しない部分とは、セパレータ基材６０を切断中に切断箇所に接触しない部分である。そして、切断部材１１０の表面のうち切断に寄与しない部分であって、かつセパレータ基材６０に接触する部分（断熱必要部分１２１ｃ）とは、切断作業中にセパレータ基材６０と切断箇所ではない部分で接触する部分である。なお、本実施形態では、切断部材１１０の表面のうち切断に寄与しない部分であって、かつセパレータ基材６０に対向する部分全面に断熱部材１４０を設けている場合を例示している。 The portion of the cutting member 110 that contributes to the cutting is a portion that contacts the cutting portion during the cutting of the separator base material 60 and refers to the blade edge 121a. The blade edge 121a is a portion of the blade 121 having a predetermined length T from the blade tip 121b. The predetermined length T is set according to the size of the concave portion 170b of the mounting member 170 and the shape of the blade 121, and is not determined to be a unique value. Therefore, the portion of the cutting member 110 that does not contribute to cutting is a portion that does not come into contact with the cut portion during cutting of the separator base material 60. And the part which does not contribute to cutting | disconnection on the surface of the cutting member 110, and is a part (heat insulation required part 121c) which contacts the separator base material 60 is a part which is not a separator base material 60 and a cutting | disconnection location during a cutting operation. This is the part that contacts. In the present embodiment, the case where the heat insulating member 140 is provided on the entire surface of the surface of the cutting member 110 that does not contribute to cutting and faces the separator substrate 60 is illustrated.
断熱部材１４０の材料は、たとえば、織布、不織布、発泡材、真空断熱材および熱吸収材から構成される材料を用いている。切断部材１１０の表面のうち切断に寄与しない部分であって、かつセパレータ基材６０と接触する部分（断熱必要部分１２１ｃ）を覆うように貼り付けられている。断熱部材１４０は、図示しない接着材を介して切断部材１１０に貼り付けられている。接着材は、公知の接着材を用いることができ、限定されない。なお、断熱部材１４０は、切断部１２０とともに基部１３０から着脱可能な構成からなる。しかしながら、これに限定することはなく、たとえば、切断部材１１０に貼り付けられている断熱部材と、基部１３０に貼り付けられている断熱部材とをそれぞれ別の部材で設けてもよい。 As a material of the heat insulating member 140, for example, a material composed of a woven fabric, a nonwoven fabric, a foam material, a vacuum heat insulating material, and a heat absorbing material is used. The portion of the surface of the cutting member 110 that does not contribute to cutting and is attached so as to cover the portion that contacts the separator substrate 60 (the heat insulation required portion 121c). The heat insulating member 140 is affixed to the cutting member 110 via an adhesive (not shown). A known adhesive can be used as the adhesive, and is not limited. The heat insulating member 140 is configured to be detachable from the base portion 130 together with the cutting portion 120. However, the present invention is not limited to this. For example, the heat insulating member attached to the cutting member 110 and the heat insulating member attached to the base 130 may be provided as separate members.
断熱部材１４０は、上述したように、切断部材１１０の表面のうち切断に寄与しない部分であって、かつセパレータ基材６０に接触する部分（断熱必要部分１２１ｃ）に設けられる。このため、加熱した切断部材１１０の表面のうち当該部分（断熱必要部分１２１ｃ）は、断熱部材１４０を介してセパレータ基材６０と接触するので、セパレータ基材６０の当該接触部分を溶融することはない。したがって、切断部材１１０に断熱部材１４０を設けることにより、切断部材１１０に固着する樹脂を低減できるので、切断性の悪化を遅らせることができ、切断部材１１０の工具寿命を延ばすことができる。また、切断部材１１０に断熱部材１４０を設けることにより、セパレータ基材６０の切断箇所以外の部分を溶融しないため、切断形状、寸法などに関わる品質の低下を抑制することができる。 As described above, the heat insulating member 140 is provided on a portion of the surface of the cutting member 110 that does not contribute to cutting and that is in contact with the separator base 60 (heat insulating necessary portion 121c). For this reason, since the said part (heat insulation required part 121c) among the surfaces of the heated cutting member 110 contacts the separator base material 60 via the heat insulation member 140, melting the said contact part of the separator base material 60 is not possible. Absent. Therefore, by providing the heat insulating member 140 on the cutting member 110, the resin adhering to the cutting member 110 can be reduced, so that the deterioration of the cutting performance can be delayed and the tool life of the cutting member 110 can be extended. Moreover, since the heat insulation member 140 is provided in the cutting member 110, since parts other than the cutting location of the separator base material 60 are not melted, it is possible to suppress deterioration in quality related to the cutting shape, dimensions, and the like.
また、切断部材１１０の表面のうち断熱必要部分１２１ｃに断熱部材１４０を設けることにより、当該部分に樹脂が固着することを防止することができる。切断部材１１０の表面のうち断熱必要部分１２１ｃに樹脂が固着すると、切断時にこの固着した樹脂とセパレータ基材６０の切断箇所以外の部分とが接触し、セパレータ基材６０の切断箇所以外の部分を傷つけることがある。したがって、断熱部材１４０を設けることにより、セパレータ基材６０のうち切断箇所以外の部分が傷つくことを防止することができ、これにより、セパレータ６１の品質の低下を抑制することができる。 Moreover, it can prevent that resin adheres to the said part by providing the heat insulation member 140 in the heat insulation required part 121c among the surfaces of the cutting member 110. FIG. When the resin adheres to the heat insulation necessary portion 121c of the surface of the cutting member 110, the fixed resin and a portion other than the cut portion of the separator base 60 are in contact with each other at the time of cutting. May hurt. Therefore, by providing the heat insulating member 140, it is possible to prevent the portions other than the cut portion of the separator base material 60 from being damaged, thereby suppressing the deterioration of the quality of the separator 61.
図３および図４に示すように、切断部材１１０は、切断部１２０が基部１３０に対して着脱可能に取り付けられる。切断部材１１０は、切断部１２０と基部１３０とが係合部１６０を介して嵌り合ってなる。 As shown in FIGS. 3 and 4, the cutting member 110 is attached so that the cutting portion 120 is detachably attached to the base portion 130. The cutting member 110 is configured such that the cutting part 120 and the base part 130 are fitted via the engaging part 160.
係合部１６０は、切断部１２０と基部１３０とが嵌り合うために設けられる。係合部１６０として、切断部１２０は、基部１３０と接する刃１２１の後端１２１ｄに基部１３０と嵌り合うための凸部１２１ｅを有している。係合部１６０として、基部１３０は、切断部１２０の刃１２１の凸部１２１ｅと嵌り合うための凹部１３０ａを有している。凸部１２１ｅの形状は、加工し易い矩形形状に形成している。 The engaging part 160 is provided so that the cutting part 120 and the base part 130 fit together. As the engaging part 160, the cutting part 120 has a convex part 121 e for fitting with the base part 130 at the rear end 121 d of the blade 121 in contact with the base part 130. As the engaging part 160, the base part 130 has a concave part 130 a for fitting with the convex part 121 e of the blade 121 of the cutting part 120. The shape of the convex part 121e is formed in a rectangular shape that is easy to process.
このように、切断部材１１０では、基部１３０から切断部１２０を取り外し、消耗品である切断部１２０のみを交換することができる。したがって、基部１３０と一体型の切断部の場合と比べ、工具交換にかかる工数を低減することができるので、部品交換性を向上でき、これにより、装置のセット性を向上することができる。また、基部１３０から切断部１２０を容易に着脱できるので、清掃頻度を含む保全性を向上することができる。 Thus, in the cutting member 110, the cutting part 120 can be removed from the base 130, and only the cutting part 120 that is a consumable item can be replaced. Therefore, compared with the case where the base portion 130 and the integrated cutting portion are used, the number of man-hours required for tool change can be reduced, so that the component changeability can be improved, thereby improving the setability of the apparatus. Moreover, since the cutting | disconnection part 120 can be easily attached or detached from the base 130, the maintainability including the cleaning frequency can be improved.
また、切断部材１１０では、係合部１６０として、切断部１２０の刃１２１の後端１２１ｄに設けた凸部１２１ｅと、基部１３０の凹部１３０ａとが嵌り合うので、切断部１２０は、基部１３０に対して着脱可能に取り付けることができる。 Moreover, in the cutting member 110, since the convex part 121e provided in the rear end 121d of the blade 121 of the cutting part 120 and the concave part 130a of the base part 130 fit as the engaging part 160, the cutting part 120 is attached to the base part 130. On the other hand, it can be detachably attached.
係合部１６０は、切断部材１１０がセパレータ基材６０に対して相対的に接近離反移動する方向に沿って切断部１２０と基部１３０とが分離することを防止する引っ掛かり形状を有している。 The engaging portion 160 has a hook shape that prevents the cutting portion 120 and the base portion 130 from separating along the direction in which the cutting member 110 moves relative to and away from the separator substrate 60.
係合部１６０は、切断部１２０と基部１３０とが嵌り合った状態から分離することを防止するために設けている。係合部１６０として、切断部１２０は、刃１２１の凸部１２１ｅにおいて、凸部１２１ｅから載置面１７０ａに対して水平方向に延長する矩形状の引っ掛かり形状を有している。係合部１６０として、基部１３０は、凹部１３０ａにおいて、切断部１２０の刃１２１の引っ掛かり形状を有する凸部１２１ｅを嵌め入れて引っ掛けるための形状を有している。 The engaging part 160 is provided to prevent the cutting part 120 and the base part 130 from being separated from the fitted state. As the engaging portion 160, the cutting portion 120 has a rectangular hook shape extending in the horizontal direction from the convex portion 121 e to the placement surface 170 a at the convex portion 121 e of the blade 121. As the engaging portion 160, the base portion 130 has a shape for fitting and hooking the convex portion 121e having the hook shape of the blade 121 of the cutting portion 120 in the concave portion 130a.
このように、切断部材１１０がセパレータ基材６０に対して相対的に接近離反移動する際、係合部１６０の構成により、基部１３０は、切断部１２０を確実に引っ掛けて保持する。このため、係合部１６０は、切断部材１１０がセパレータ基材６０に対して相対的に接近離反移動する方向に沿って切断部１２０と基部１３０とが分離することを防止することができる。したがって、切断部材１１０は、切断部１２０と基部１３０とが引っ掛かり形状を有する係合部１６０を介して嵌り合っているので、切断部１２０と基部１３０とを分離可能な構成にしながらも、保全性を向上することができる。 Thus, when the cutting member 110 moves relatively close to and away from the separator substrate 60, the base portion 130 reliably hooks and holds the cutting portion 120 due to the configuration of the engaging portion 160. For this reason, the engaging part 160 can prevent the cutting part 120 and the base part 130 from being separated along the direction in which the cutting member 110 moves relative to and away from the separator substrate 60 relatively. Therefore, since the cutting member 110 is fitted to the cutting part 120 and the base part 130 via the engaging part 160 having a hooked shape, the cutting part 120 and the base part 130 can be separated from each other, but the safety can be maintained. Can be improved.
切断部材１１０は、切断部１２０と基部１３０とを焼き嵌めによって嵌め合ってなる。 The cutting member 110 is formed by fitting the cutting part 120 and the base part 130 by shrink fitting.
切断部１２０と基部１３０との組み付け方について説明を行う。たとえば図示しない外部の加熱手段により基部１３０を熱すると、基部１３０が膨張して係合部１６０を構成する凹部１３０ａが広がる。このとき、広がった基部１３０の凹部１３０ａに切断部１２０の刃１２１の凸部１２１ｅを嵌め込む。その後、切断部１２０と基部１３０とが冷えると、切断部１２０と基部１３０とは組み合う。なお、焼き嵌め時において、外部の加熱手段が基部１３０を加熱する温度は、加熱部材１３１が基部１３０を加熱する温度よりも高い温度である。 A method of assembling the cutting part 120 and the base part 130 will be described. For example, when the base 130 is heated by an external heating means (not shown), the base 130 expands and the concave portion 130a constituting the engaging portion 160 is expanded. At this time, the convex part 121e of the blade 121 of the cutting part 120 is fitted into the concave part 130a of the base part 130 that has spread. Thereafter, when the cutting part 120 and the base part 130 cool, the cutting part 120 and the base part 130 are assembled. At the time of shrink fitting, the temperature at which the external heating means heats the base 130 is higher than the temperature at which the heating member 131 heats the base 130.
このように、基部１３０の凹部１３０ａに切断部１２０の刃１２１の凸部１２１ｅを焼き嵌めによって嵌め込んで組み合わせることにより、基部１３０と切断部１２０との組み合わせのズレを防止することができる。また、切断部材１１０が載置面１７０ａ方向に接近または離反する動作を行った場合において、基部１３０から切断部１２０が脱落することを防止できる。したがって、切断部１２０と基部１３０とを焼き嵌めによって嵌め合うことにより、切断部１２０と基部１３０とをより強固に連結することができる。 In this way, by combining the convex portion 121e of the blade 121 of the cutting portion 120 with the concave portion 130a of the base portion 130 by shrink fitting, it is possible to prevent the deviation of the combination of the base portion 130 and the cutting portion 120. In addition, when the cutting member 110 performs an operation of approaching or moving away from the mounting surface 170a, it is possible to prevent the cutting unit 120 from dropping from the base 130. Therefore, the cutting part 120 and the base part 130 can be more firmly connected by fitting the cutting part 120 and the base part 130 together by shrink fitting.
切断部材１１０は、基部１３０を形成する材料の熱膨張率が、切断部１２０を形成する材料の熱膨張率よりも高い。 In the cutting member 110, the material forming the base 130 has a higher coefficient of thermal expansion than the material forming the cutting part 120.
上記したように、基部１３０を形成する材料は、たとえば上記の黄銅Ｃ２６００であり、切断部１２０を形成する材料は、たとえば上記の黄銅Ｃ２８０１である。黄銅Ｃ２６００の熱膨張率は、黄銅Ｃ２８０１の熱膨張率よりも高い。このように、基部１３０の材料に、切断部１２０の材料よりも熱膨張率の高い材料を用いることにより、上記焼き嵌めの際に、基部１３０の凹部１３０ａに切断部１２０の刃１２１の凸部１２１ｅを容易に嵌め込むことができる。 As described above, the material forming the base portion 130 is, for example, the above-described brass C2600, and the material forming the cutting portion 120 is, for example, the above-described brass C2801. The thermal expansion coefficient of brass C2600 is higher than that of brass C2801. In this way, by using a material having a higher coefficient of thermal expansion than the material of the cutting part 120 as the material of the base part 130, the convex part of the blade 121 of the cutting part 120 in the concave part 130a of the base part 130 during the shrink fitting. 121e can be easily fitted.
制御部材２００は、加工機１０全体を制御し、切断装置１００においては、切断部材１１０の切断部１２０および加熱部材１３１の作動を制御する。制御部材２００は、ＲＯＭ、ＣＰＵ、およびＲＡＭを含んでいる。ＲＯＭ（Ｒｅａｄ Ｏｎｌｙ Ｍｅｍｏｒｙ）は、切断装置１００の各部を制御するための各種制御プログラムを格納している。ＣＰＵ（Ｃｅｎｔｒａｌ Ｐｒｏｃｅｓｓｉｎｇ Ｕｎｉｔ）は、各種制御プログラムに基づいて、各部を制御する。ＲＡＭ（Ｒａｎｄｏｍ Ａｃｃｅｓｓ Ｍｅｍｏｒｙ）は、制御中の各種データを一時的に記憶する。 The control member 200 controls the entire processing machine 10, and in the cutting apparatus 100, controls the operation of the cutting unit 120 and the heating member 131 of the cutting member 110. The control member 200 includes a ROM, a CPU, and a RAM. A ROM (Read Only Memory) stores various control programs for controlling each part of the cutting apparatus 100. A CPU (Central Processing Unit) controls each unit based on various control programs. A RAM (Random Access Memory) temporarily stores various data under control.
制御部材２００は、加熱部材１３１に電流を供給し、加熱部材１３１で生じた熱により切断部１２０の刃１２１を加熱するように制御する。これによって、加熱部材１３１は、刃１２１を加熱することが可能となっている。 The control member 200 supplies current to the heating member 131 and controls the blade 121 of the cutting unit 120 to be heated by the heat generated by the heating member 131. Thereby, the heating member 131 can heat the blade 121.
制御部材２００は、切断部材１１０を載置部材１７０に向かう方向へ接近または離反するために切断部材１１０の上下動の作動タイミングを調整自在である。これによって、切断部材１１０は、セパレータ基材６０を切断することが可能となっている。 The control member 200 can adjust the operation timing of the vertical movement of the cutting member 110 so that the cutting member 110 approaches or separates in the direction toward the mounting member 170. Thereby, the cutting member 110 can cut the separator base material 60.
つぎに、切断装置１００の動作について、図５を参照しながら説明する。 Next, the operation of the cutting device 100 will be described with reference to FIG.
図５（Ａ）〜（Ｅ）は、実施形態に係る樹脂製のセパレータ基材６０の切断装置１００がセパレータ基材６０を切断している動作を示す模式図である。 5A to 5E are schematic diagrams illustrating an operation in which the cutting device 100 for the resin separator base 60 according to the embodiment is cutting the separator base 60. FIG.
切断装置１００による切断を開始する時点では、図５（Ａ）に示すように切断部材１１０は、セパレータ基材６０と非接触の位置に配置している。まず、制御部材２００は、図５（Ｂ）（Ｃ）（Ｄ）に示すように、作動ロッド１５１を介して切断部材１１０の刃１２１がセパレータ基材６０に接触して載置部材１７０の凹部１７０ｂに引き込まれるまで切断部材１１０を押し出す。押し出した切断部材１１０の刃１２１の刃先１２１ａは、セパレータ基材６０と接触して切断し、セパレータ６１を生成する。このとき、断熱部材１４０は、切断部材１１０の表面のうち切断に寄与しない部分であって、かつセパレータ基材６０と接触する部分（断熱必要部分１２１ｃ）を断熱するため、セパレータ基材６０の切断箇所以外の部分を溶融しない。このため、断熱部材１４０は、切断部材１１０の表面のうち切断に寄与しない部分であって、かつセパレータ基材６０と接触する部分（断熱必要部分１２１ｃ）に溶融した樹脂が付着することを防止できる。 At the point of time when the cutting by the cutting device 100 is started, the cutting member 110 is disposed at a position that is not in contact with the separator substrate 60 as shown in FIG. First, as shown in FIGS. 5B, 5 </ b> C, and 5 </ b> D, the control member 200 is configured such that the blade 121 of the cutting member 110 comes into contact with the separator substrate 60 via the operating rod 151 and the concave portion of the mounting member 170. The cutting member 110 is pushed out until it is pulled into 170b. The blade edge 121a of the blade 121 of the extruded cutting member 110 comes into contact with the separator substrate 60 and cuts to generate the separator 61. At this time, the heat insulating member 140 is a portion of the surface of the cutting member 110 that does not contribute to cutting, and insulates the portion that comes into contact with the separator base material 60 (heat insulation necessary portion 121c). Do not melt other parts. For this reason, the heat insulating member 140 can prevent the molten resin from adhering to a portion that does not contribute to cutting on the surface of the cutting member 110 and is in contact with the separator base 60 (heat insulating necessary portion 121c). .
つぎに、切断部材１１０は、図５（Ｅ）に示すように、作動ロッド１５１を元の位置に引き戻す。これにより、作動ロッド１５１に基部１３０を介して取り付けられている切断部材１１０は、セパレータ基材６０および載置部材１７０から離反する。 Next, the cutting member 110 pulls the operating rod 151 back to the original position as shown in FIG. As a result, the cutting member 110 attached to the operating rod 151 via the base 130 is separated from the separator substrate 60 and the mounting member 170.

Therefore, compared with the case where the cutting portion is integrated with the base portion 130, the number of man-hours required for tool change can be reduced, and the setability of the apparatus can be improved.
さらに、本切断装置１００では、切断部材１１０は、切断部１２０と基部１３０とが係合部１６０を介して嵌り合ってなる。 Further, in the cutting device 100, the cutting member 110 is configured such that the cutting part 120 and the base part 130 are fitted via the engaging part 160.
かような構成によれば、本切断装置１００では、係合部１６０として、切断部１２０の刃１２１の後端１２１ｄに設けた凸部１２１ｅと、基部１３０の凹部１３０ａとが嵌り合うので、切断部１２０は、基部１３０に対して着脱可能に取り付けることができる。 According to such a configuration, in the present cutting device 100, as the engaging portion 160, the convex portion 121e provided at the rear end 121d of the blade 121 of the cutting portion 120 and the concave portion 130a of the base portion 130 fit with each other. The part 120 can be detachably attached to the base part 130.
さらに、本切断装置１００では、係合部１６０は、切断部材１１０がセパレータ基材６０に対して相対的に接近離反移動する方向に沿って切断部１２０と基部１３０とが分離することを防止する引っ掛かり形状を有する。 Further, in the cutting apparatus 100, the engaging portion 160 prevents the cutting portion 120 and the base portion 130 from separating along the direction in which the cutting member 110 moves relative to and away from the separator substrate 60. It has a hook shape.
