Description

本発明は、例えば点火コイルや変圧器などのコイル内に内挿される鉄芯(磁性ブロック)として用いられる積層コアを製造するための積層材を製造する積層コア製造用の積層材製造装置並びに積層コア製造用の積層材製造方法に関するものである。   The present invention relates to a laminated material production apparatus for producing a laminated material for producing a laminated material for producing a laminated core used as an iron core (magnetic block) inserted in a coil such as an ignition coil or a transformer, and a laminated material The present invention relates to a method for manufacturing a laminated material for manufacturing a core.

例えば珪素鋼板などの短冊状の単板(切断片)を、順次板幅が増大し減少するように板厚方向に積み重ね、この積層体の断面(側面視)が例えば略円形(全体で略円柱形状)となるように積層形成した積層材を製造し、これを接着してブロック状の積層コアを製造するが、このような積層コアは、例えばこのように断面略円形に積層すると、コイル断面に対して磁性ブロックとしての充填効率が良く小型対応可能となるため、様々な円形コイルの磁性ブロックとして好ましく用いられている。   For example, strip-shaped single plates (cut pieces) such as silicon steel plates are sequentially stacked in the plate thickness direction so that the plate width increases and decreases, and the cross section (side view) of this laminate is, for example, substantially circular (as a whole, approximately cylindrical) A laminated material formed in a laminated shape so as to have a shape) and bonded together to produce a block-shaped laminated core. When such a laminated core is laminated in a substantially circular cross section, for example, On the other hand, since the filling efficiency as a magnetic block is good and the size can be reduced, it is preferably used as a magnetic block of various circular coils.

このような積層コアの主要部となる積層材を製造するために、板材をプレス加工により打ち抜いてこれを積層すると、高価な金型が必要となったり金型交換作業もやっかいとなったりして、製造コストがかかり、また打ち抜きしろが必要となるため材料歩留りも悪く材料ロスもあり、積層工程も要し、生産性が悪く実用性に劣る。   In order to produce a laminated material that is the main part of such a laminated core, punching the plate material by pressing and laminating it requires expensive molds and cumbersome mold replacement work. In addition, the manufacturing cost is high, and punching is required, so the material yield is poor, there is a material loss, the lamination process is required, the productivity is poor and the practicality is inferior.

一方、フープ材(例えば連続供給される珪素鋼板などの磁性板)の切断幅を調整して次々と切断しこの切断片を積層すると、抜きしろは不要で材料ロスもなく高価な金型も不要で、安価にして効率良く積層材を積層形成できることになるが、このフープ材の送り量のバラつきにより切断幅の寸法精度が安定せず寸法精度の高い積層コアを製造することは困難であった(特開平10−163051号)。   On the other hand, by adjusting the cutting width of the hoop material (for example, a magnetic plate such as a silicon steel plate that is continuously supplied) and cutting it one after another, this cutting piece is laminated, so there is no need to remove it and no expensive metal mold is required. However, the laminate material can be efficiently laminated at a low cost, but due to the variation in the feed amount of the hoop material, it is difficult to produce a laminated core with high dimensional accuracy because the dimensional accuracy of the cutting width is not stable. (Japanese Patent Laid-Open No. 10-163051).

例えば、特開平10−163051号などの従来装置では、フープ材の送り量は一定とし、送り方向(フープ材搬送方向)に一対設けた切断装置間の間隔を調整設定することで切断片の切断幅を調整する構成のため、この切断装置の移動調整精度は高められないし、またフープ材の送り量のバラつきも抑えることができないため、切断片を増大・減少させて積層させる積層材の寸法精度を高くすることは困難であった。   For example, in a conventional apparatus such as Japanese Patent Laid-Open No. 10-163051, the hoop material feed amount is constant, and the interval between a pair of cutting devices provided in the feed direction (the hoop material transport direction) is adjusted and set to cut the cut piece. Because of the configuration that adjusts the width, the movement adjustment accuracy of this cutting device cannot be increased, and the variation in the feed amount of the hoop material cannot be suppressed, so the dimensional accuracy of the laminated material that stacks by increasing or decreasing the number of cut pieces It was difficult to increase the value.

材料を送る搬送装置をエアーフィーダ方式としても、送り精度を高めることはできない。   Even if the conveying device for feeding the material is an air feeder system, the feeding accuracy cannot be increased.

A feed roller that intermittently conveys the hoop material is disposed at a position close to the cutting position so that the influence of deflection due to its own weight is small, and this feed roller is driven by a rotational drive source such as a stepping motor or servo motor. Even when a rotation transmission mechanism is provided, it is driven by a belt or gear without backlash, and the feed width of the hoop material by this feed roller is controlled by a preset program to adjust and control the cutting width of the cut piece It is possible to obtain a laminated core made of a laminated material with a high dimensional accuracy with a simple configuration.

本発明は上述のように構成したから、フープ材の支承部から突出した送り突出部分を切断可動部によって切断する構成とすると共に、このフープ材の歪みや自重によるたわみの影響が少ないように切断位置に近接させた位置に、フープ材を間欠搬送する送りローラを配設し、この送りローラを例えばステッピングモータやサーボモータなどの回動駆動源で駆動し、予め設定したプログラムによりこの送りローラによるフープ材の送り量を制御して切断片の切断幅を調整制御するように構成したため、簡易な構成で量産性に優れ高い寸法精度の積層材による積層コアを得ることのできる極めて実用性に優れた画期的な積層コア製造用の積層材製造装置となる。   Since the present invention is configured as described above, the feed projecting portion projecting from the support portion of the hoop material is cut by the movable cutting portion, and the hoop material is cut so as not to be affected by the distortion or the weight due to its own weight. A feed roller that intermittently conveys the hoop material is disposed at a position close to the position, and this feed roller is driven by a rotational drive source such as a stepping motor or a servo motor, and the feed roller is driven by a preset program. The hoop material feed amount is controlled to adjust and control the cutting width of the cut piece, so it is possible to obtain a laminated core made of a laminated material with high dimensional accuracy with a simple structure and excellent mass production. This is a revolutionary laminated material production apparatus for producing laminated cores.

また、請求項2記載の発明においては、排出落差を略一定に加減できるため、切断片が乱れずにきれいに整列積層できるため、これを束ねて接着止めして積層コアを製造する次工程への供給やその工程作業が良好となるなど一層優れた積層コア製造用の積層材製造装置となる。   Further, in the invention according to claim 2, since the discharge drop can be adjusted substantially constant, the cut pieces can be neatly aligned and laminated without being disturbed, so that the bundle core is bundled and bonded to produce a laminated core. It becomes a more excellent laminated material manufacturing apparatus for manufacturing a laminated core such that the supply and the process work are good.

即ち、排出部下降装置を備えることで、例えば適度な落差とすることができ、自重により良好な自動積層を実現でき、積層高さの増大に応じて順次下降させてこの適度な落差を保持することで、落下衝撃による回転や方向の乱れを防止でき、きれいに整列積層できるため、次工程での整列作業が容易となる。   That is, by providing the discharge unit lowering device, for example, it is possible to achieve a moderate drop, it is possible to realize a good automatic stacking by its own weight, and keep this moderate drop by sequentially lowering as the stacking height increases. Thus, rotation and direction disturbance due to a drop impact can be prevented, and neat alignment and lamination can be performed, so that the alignment operation in the next process becomes easy.

また、請求項3記載の発明においては、送りローラがプログラム制御されてフープ材を間欠搬送し、所望の切断幅だけ支承部より突出させ、これを切断可動部を可動して切断する毎に、このタイミングに合わせて支承部にフープ材を押さえ付ける押さえ付け部を設けたから、一層切断片の切断幅の寸法精度が高まり高い寸法精度の積層材(積層コア)を得ることができるなど、一層優れた積層コア製造用の積層材製造装置となる。   Further, in the invention of claim 3, the feed roller is program-controlled to intermittently convey the hoop material, and protrudes from the support part by a desired cutting width, each time the cutting movable part is moved and cut, Since the holding part that presses the hoop material to the support part is provided in accordance with this timing, the dimensional accuracy of the cutting width of the cut piece is further increased, and a highly dimensional accurate laminated material (laminated core) can be obtained. It becomes a laminated material manufacturing apparatus for manufacturing a laminated core.

また、請求項4記載の発明においては、必要に応じて積層コアを固定するために利用する穴を自動開口でき、この穴開け装置はあくまで送り量をプログラム制御する送りローラよりも搬送上流側に配設するため、穴を開ける場合でも前記高い寸法精度を維持できる優れた積層コア製造用の積層材製造装置となる。   Further, in the invention described in claim 4, a hole used for fixing the laminated core can be automatically opened as needed, and this hole punching device is located upstream of the feed roller for program-controlling the feed amount. Therefore, even when a hole is made, the laminated material manufacturing apparatus for manufacturing an excellent laminated core that can maintain the high dimensional accuracy can be obtained.

また、請求項5記載の発明においては、フープ材の材料厚にバラつきがある場合、積層材の積層高さの精度をも向上させるため、例えば積層高さの測定値に応じて切断片の積層枚数を増減させて微調整することが極めて容易に行える画期的な積層コア製造用の積層材製造装置となる。   Further, in the invention according to claim 5, in the case where the material thickness of the hoop material varies, in order to improve the accuracy of the stacking height of the stacking material, for example, the stacking of the cut pieces according to the measured value of the stacking height This is an epoch-making laminated material manufacturing apparatus for manufacturing a laminated core that can be finely adjusted by increasing / decreasing the number of sheets.

また、請求項6記載の発明においては、切断片の片側端縁に切断によるダレ(これによるバリ)が生じていても、積層材の途中(特に同幅寸法の切断片が積層される場合)で、表裏反転させて積層するようにすることで片寄りなくきれいに積層でき、寸法精度の高い積層材(積層コア)を得ることができ、また次工程での一体化が良好に行え隙間による漏洩磁束も発生しにくく効率を損なわない積層コアを得ることができる優れた積層コア製造用の積層材製造方法となる。   Further, in the invention according to claim 6, even if a sag due to cutting (burr caused by this) occurs at one side edge of the cut piece, it is in the middle of the laminated material (especially when cut pieces having the same width are laminated). By turning the layers upside down, the layers can be laminated cleanly without any deviation, and a laminate with high dimensional accuracy (laminated core) can be obtained. In addition, the next process can be well integrated and leakage due to gaps. This is an excellent method for producing a laminated material for producing a laminated core that can obtain a laminated core that hardly generates magnetic flux and does not impair efficiency.

好適と考える本発明の実施形態を、図面に基づいて本発明の作用を示して簡単に説明する。   An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

フープ材1は、搬送装置2の送りローラ6により送り駆動される。例えばこのフープ材1を支持若しくは他の支承ローラ16(挟持ローラ16)と挟持しながら送り駆動する前記送りローラ6によりこのフープ材1を間欠搬送する。例えばこの送りローラ6の間欠駆動によりフープ材1が巻回されている供給ロール14からフープ材1が引き出され支承ローラ16(挟持ローラ16)などから成る搬送ガイド部7により搬送ガイドされて切断装置3へ間欠搬送される。   The hoop material 1 is fed and driven by the feed roller 6 of the transport device 2. For example, the hoop material 1 is intermittently conveyed by the feed roller 6 which feeds and drives while supporting the hoop material 1 or sandwiching it with another support roller 16 (nip roller 16). For example, the hoop material 1 is pulled out from the supply roll 14 around which the hoop material 1 is wound by the intermittent driving of the feed roller 6 and is transported and guided by a transport guide portion 7 including a support roller 16 (clamping roller 16). 3 is intermittently conveyed.

この切断装置3は、フープ材1の先端部を支承する支承部8と、この支承部8に支承され、この支承部8から突出した送り突出部分を切断する切断可動部9とからなり、前記送りローラ6の間欠駆動により間欠搬送するフープ材1の先端部は、切断毎に前記支承部8から送り突出し、この支承部8からの送り突出部分が切断可動部9の可動により順次切断され、この切断片1Aは排出部4に落下排出されて積層し、積層材5が排出部4に積層形成される。   The cutting device 3 includes a support portion 8 that supports the tip portion of the hoop material 1, and a cutting movable portion 9 that is supported by the support portion 8 and that cuts a feed protruding portion protruding from the support portion 8. The front end portion of the hoop material 1 that is intermittently conveyed by intermittent driving of the feed roller 6 is fed out from the support portion 8 every time it is cut, and the feed protrusion portion from the support portion 8 is sequentially cut by the movement of the cutting movable portion 9. The cut pieces 1 </ b> A are dropped and discharged onto the discharge unit 4 and stacked, and the laminated material 5 is stacked on the discharge unit 4.

この送りローラ6を間欠駆動する回動駆動源13の回動量を、送りローラ制御部10によりプログラム制御して、前記フープ材1の送り量を可変制御しフープ材1の切断幅を調整制御する。   The feed amount of the turning drive source 13 that intermittently drives the feed roller 6 is controlled by the feed roller control unit 10 so that the feed amount of the hoop material 1 is variably controlled and the cutting width of the hoop material 1 is adjusted and controlled. .

即ち、この送りローラ制御部10によりフープ材1の送り量を制御してフープ材1の切断幅を徐々に増加若しくは徐々に減少又はこの増加と減少の組み合わせにより、前記排出部4に前記短冊状の切断片1Aが積層され、側面視で台形,ひし形,円形などの所望形に造形された積層材5が積層形成される。   That is, the feed roller control unit 10 controls the feed amount of the hoop material 1 to gradually increase or decrease the cutting width of the hoop material 1 or to combine the increase and decrease with the strip shape on the discharge unit 4. The cut pieces 1A are laminated, and a laminated material 5 shaped into a desired shape such as a trapezoid, a rhombus, or a circle in a side view is laminated.

尚、例えば側面視円形で全体として円柱状のブロック状積層材5を積層形成する場合、本発明は板材の積層のため、円形なる表現は、完全な円形を意味するものでなく、また最下板や最上板の幅寸法が0でなく所定幅を有し全体として上下が面取りされたような形状を含む意味であり、また更に一部に後述する同幅寸法の切断片1Aが積層された同幅積層部分5Aを有する形状の場合を含む意味で、これらを含めて円形と記載するが、これらを含んでいることを明確にするため略円形や略半円形などのように表現する場合もある。   For example, in the case of laminating and forming a cylindrical block-shaped laminated material 5 as a whole in a circular shape in a side view, because the present invention is a lamination of plate materials, the expression of a circle does not mean a complete circle, and the bottom This means that the width of the plate or the uppermost plate is not 0 but has a predetermined width and the shape is such that the upper and lower surfaces are chamfered as a whole. Including the shape having the same width laminated portion 5A, it is described as a circle including these, but it may be expressed as a substantially circular shape or a semi-circular shape in order to clarify that these are included. is there.

即ち、例えば、フープ材1の送り量を予め設定するプログラムにより送りローラ6による送り量を制御して、フープ材1の切断幅が徐々に増加し、更に徐々に減少するようにして排出部4に側面視あるいは切断面が略円形に造形され、又は徐々に増加若しくは減少するようにして略半円形に造形された積層材5を一方を上下逆にして合せて略円形の積層材5を得ることができ、一部に同幅積層部分5Aを有していて形状としても良い。   In other words, for example, the feed amount of the hoop material 1 is controlled by a program for presetting the feed amount of the hoop material 1 so that the cutting width of the hoop material 1 is gradually increased and further gradually decreased. The laminated material 5 shaped into a substantially semicircular shape in which the side view or the cut surface is shaped into a substantially circular shape or gradually increased or decreased is turned upside down to obtain a substantially circular laminated material 5. The same width laminated portion 5A may be provided in part and may be shaped.

言い換えると、一挙に略円形の積層材5を積層形成しても良いが、例えば切断幅が徐々に増加するように制御して略半円形の積層材5を積層形成し、これを逆向きに合せ(底面同士を合せて)積層して全体として側面視略円形となる略円柱状の積層材5を得るようにしても良い。   In other words, the substantially circular laminated material 5 may be laminated at once, but for example, the substantially semicircular laminated material 5 is laminated by controlling the cutting width to gradually increase, and this is reversed. It is also possible to obtain a substantially columnar laminated material 5 that is laminated (by combining the bottom surfaces) and is generally circular in a side view.

また、この搬送装置2の送りローラ6は、前記切断装置3の支承部8に近接した位置に設ける。   Further, the feed roller 6 of the transport device 2 is provided at a position close to the support portion 8 of the cutting device 3.

具体的には、前記送りローラ6を前記切断装置3の搬送手前側にして且つ前記フープ材1の歪み若しくは自重によるたわみによる送り誤差が許容誤差範囲内となる近接位置に配設している。   Specifically, the feed roller 6 is disposed on the front side of the cutting device 3 and is disposed at a close position where a feed error due to distortion of the hoop material 1 or deflection due to its own weight falls within an allowable error range.

これにより、例えば送りローラ6をステッピングモータやサーボモータなどの送り精度の高い回動駆動源13で駆動し、この送り量を予め設定したプログラムに基づいて制御すると共に、このように送りローラ6を切断位置となる支承部8にできるだけ近づけることでフープ材1の歪みやたわみによる送り誤差も小さくでき、これまでにない送り精度の高い材料送りを実現でき、この精度の高い材料送りを制御することにより徐々に増加若しくは減少又は一部一定とする各切断幅が高い精度で微調整できることにより、簡単な構成でありながら極めて高い寸法精度でフープ材1を積層して所望形に造形でき、よって寸法精度の高い積層材5(積層コア)を得ることができる。   As a result, for example, the feed roller 6 is driven by a rotational drive source 13 having a high feed accuracy such as a stepping motor or a servo motor, and the feed amount is controlled based on a preset program. The feed error due to distortion and deflection of the hoop material 1 can be reduced by bringing it as close as possible to the support portion 8 as a cutting position, and material feed with high feed accuracy that has never been achieved can be realized, and this highly precise material feed can be controlled. Each cutting width that is gradually increased, decreased, or partially constant can be finely adjusted with high accuracy, so that the hoop material 1 can be laminated with extremely high dimensional accuracy and shaped into a desired shape while having a simple configuration. A highly accurate laminated material 5 (laminated core) can be obtained.

即ち、フープ材1の支承部8から突出した送り突出部分を簡易で安価な切断可動部9の可動によって切断する構成とすると共に、このフープ材1の歪みや自重によるたわみの影響が少ないように切断位置に近接させた位置に、フープ材1を間欠搬送する送りローラ6を配設し、この送りローラ6を例えばステッピングモータやサーボモータなどの高い送り精度の回動駆動源13で駆動し、また回転伝達機構を設ける場合もバックラッシュのないベルトやギヤなどにより伝達駆動して、予め設定したプログラムによりこの送りローラ6によるフープ材1の送り量を制御して切断片1Aの切断幅を制御するように構成することで、簡易な構成で高い寸法精度の積層材5による積層コアを得ることができることとなる。   That is, the feed projecting portion protruding from the support portion 8 of the hoop material 1 is cut by the simple and inexpensive movement of the cutting movable portion 9, and the influence of the distortion of the hoop material 1 and the deflection due to its own weight is reduced. A feed roller 6 that intermittently conveys the hoop material 1 is disposed at a position close to the cutting position, and this feed roller 6 is driven by a rotational feed source 13 with high feed accuracy such as a stepping motor or a servo motor. Also, when a rotation transmission mechanism is provided, transmission is driven by a belt or gear without backlash, and the feed amount of the hoop material 1 by the feed roller 6 is controlled by a preset program to control the cutting width of the cut piece 1A. By configuring as described above, it is possible to obtain a laminated core made of the laminated material 5 having a high dimensional accuracy with a simple configuration.

本発明の具体的な実施例について図面に基づいて説明する。   Specific embodiments of the present invention will be described with reference to the drawings.

本実施例は、例えば珪素鋼板を巻回した供給ロール14から引き出されるフープ材1を搬送する搬送装置2の搬送先端部に切断装置3を設けて、フープ材1を次々と短冊状に切断し切断片1Aを切断装置3に隣接した排出受部である排出部4に落下排出して行き積層コア製造用の積層材5を積層形成する構成としている。   In the present embodiment, for example, a cutting device 3 is provided at the transport tip of the transport device 2 that transports the hoop material 1 drawn from a supply roll 14 wound with a silicon steel plate, and the hoop material 1 is cut into strips one after another. The cut piece 1A is dropped and discharged to a discharge portion 4 which is a discharge receiving portion adjacent to the cutting device 3, and a laminated material 5 for producing a laminated core is laminated.

前記搬送装置2は、前記供給ロール14からフープ材1を引き出し送り駆動する送りローラ6と、この送りローラ6により搬送される前記フープ材1をガイドして水平搬送する支承ローラ16(挟持ローラ16)などから成る搬送ガイド部7とから成り、この送りローラ6を間欠駆動してフープ材1を間欠搬送しつつ切断装置3で順次切断して行く構成としている。   The transport device 2 includes a feed roller 6 that pulls and feeds the hoop material 1 from the supply roll 14, and a support roller 16 (clamping roller 16) that guides and horizontally transports the hoop material 1 transported by the feed roller 6. ) And the like, and the feed roller 6 is intermittently driven so that the hoop material 1 is intermittently conveyed while being sequentially cut by the cutting device 3.

本実施例では、この水平搬送するフープ材1を挟持する一対の挟持ローラ16の一方の挟持ローラを送りローラ6とし、この送りローラ6の間欠回動駆動により間欠搬送する構成としている。   In the present embodiment, one of the pair of sandwiching rollers 16 that sandwich the hoop material 1 that is transported horizontally is used as a feed roller 6, and the feed roller 6 is intermittently transported by intermittent rotation driving.

前記切断装置3は、前記搬送装置2の送りローラ6の間欠駆動によりこの送りローラ6やその搬送手前側(搬送上流側)の挟持ローラ16などにガイドされて水平に間欠搬送される前記フープ材1の先端部分を支承する支承部8と、このフープ材1の先端部分の前記支承部8の端縁部から搬送方向に水平に突出する送り突出部分を切断する切断可動部9とから成る構成とし、支承部8の端縁部と切断可動部9の先鋭な下縁部とをすれ違い可動させることでフープ材1の先端部分のこの支承部8から突出している送り突出部分を間欠搬送毎次々に切断する構成としている。   The cutting device 3 is guided by the feed roller 6 or the holding roller 16 on the front side (upstream side) of the feed roller 6 by the intermittent drive of the feed roller 6 of the transport device 2, and the hoop material is intermittently transported horizontally. 1. A structure comprising a support part 8 for supporting the front end part 1 and a cutting movable part 9 for cutting a feed projecting part horizontally projecting from the end edge part of the support part 8 at the front end part of the hoop material 1 in the conveying direction. By moving the end edge portion of the support portion 8 and the sharp lower edge portion of the cutting movable portion 9 by passing each other, the feed protrusion portion protruding from the support portion 8 at the tip portion of the hoop material 1 is intermittently conveyed one after another. It is set as the structure cut | disconnected to.

即ち、支承部8に対して上下方向に可動自在に設けた切断可動部9を切断用昇降駆動装置17により下降駆動して切断する構成とし、前記送りローラ6の間欠駆動により間欠搬送するフープ材1の先端部は、切断毎に前記支承部8の端縁部から水平に送り突出され、この支承部8からの送り突出部分が切断可動部9の下動により順次切断され、この切断片1Aは排出部4上に落下排出されて積層し、積層材5が排出部4上に自動的に積層形成される構成としている。   In other words, the cutting movable portion 9 provided so as to be movable in the vertical direction with respect to the support portion 8 is configured to be driven to be lowered by the cutting lifting drive device 17 and cut, and the hoop material intermittently conveyed by the intermittent driving of the feed roller 6. 1 is horizontally fed and projected from the edge of the support portion 8 every time it is cut, and the feed projecting portion from the support portion 8 is sequentially cut by the downward movement of the cutting movable portion 9, and this cutting piece 1A Is dropped and discharged onto the discharge unit 4 and stacked, and the laminated material 5 is automatically stacked on the discharge unit 4.

この送りローラ6を間欠駆動する回動駆動源13の回動量を、送りローラ制御部10によりプログラム制御して、前記フープ材1の送り量を可変制御しフープ材1の切断幅を調整制御する構成としていて、この送りローラ6を、前記切断装置3の搬送手前側(搬送上流側)にして且つ前記フープ材1の歪み若しくは自重によるたわみによる送り誤差が許容誤差範囲内となる近接位置に配設している。   The feed amount of the turning drive source 13 that intermittently drives the feed roller 6 is controlled by the feed roller control unit 10 so that the feed amount of the hoop material 1 is variably controlled and the cutting width of the hoop material 1 is adjusted and controlled. The feed roller 6 is arranged on the front side of the cutting device 3 (on the upstream side of conveyance) and at a close position where a feed error due to distortion of the hoop material 1 or deflection due to its own weight falls within an allowable error range. Has been established.

また言い換えると、この送りローラ6を間欠駆動する回動駆動源13の回動量をプログラム制御して前記フープ材1の送り量を可変制御しフープ材1の切断幅を制御する前記送りローラ制御部10を備えて、この送りローラ制御部10によりフープ材1の送り量を制御してフープ材1の切断幅を徐々に増加若しくは徐々に減少又はこの増加と減少の組み合わせにより前記排出部4に前記短冊状の切断片1Aが積層され側面視で台形,ひし形,円形などの所望形に造形された積層材5が積層形成されるように構成している。   In other words, the feed roller controller for controlling the cutting amount of the hoop material 1 by variably controlling the feed amount of the hoop material 1 by program-controlling the rotation amount of the rotational drive source 13 that intermittently drives the feed roller 6. 10, the feed roller control unit 10 controls the feed amount of the hoop material 1, and the cutting width of the hoop material 1 is gradually increased or gradually decreased, or the discharge unit 4 is combined with the increase and decrease. The laminated material 5 is formed by laminating strip-shaped cut pieces 1A and shaped into a desired shape such as a trapezoid, a rhombus, or a circle in a side view.

具体的には、例えば側面視円形として全体として円柱状のブロック状積層材5を積層形成する場合、板材の積層のため完全な円形とはならず、また本実施例では、最下板や最上板の幅寸法は0でなく所定幅を有し全体として上下が面取りされたような円形状で、また一部に後述する同幅寸法の切断片1Aが積層された同幅積層部分5Aを有する形状であり、正確にはこのような側面視略円形で略円柱状の積層材5を積層形成する構成としている。   Specifically, for example, when the cylindrical block-shaped laminated material 5 is formed as a whole as a circular shape in a side view, it does not become a perfect circle because of the lamination of the plate materials. The width of the plate is not zero, but has a predetermined width and a circular shape with the top and bottom chamfered as a whole, and a part having the same width laminated portion 5A in which cut pieces 1A having the same width dimension described later are laminated. It is a shape, and it is configured to stack and form such a substantially cylindrical laminate material 5 having a substantially circular shape when viewed from the side.

また、前記排出部4を上下動自在に構成しこの排出部4を下降制御する排出部下降装置15を設けて、この排出部4上に積層されて行く前記積層材5の積層高さの増大に伴って徐々に下降するように構成している。   Further, the discharge unit 4 is configured to be movable up and down, and a discharge unit lowering device 15 for controlling the lowering of the discharge unit 4 is provided, so that the stacking height of the laminated material 5 stacked on the discharge unit 4 is increased. It is constituted so that it descends gradually with.

即ち、排出部下降装置15を備えることで、適度な落差とするこができ、自重による良好な自動積層を実現でき、積層高さの増大に応じて順次下降させてこの適度な落差を保持することで、落下衝撃による回転や方向の乱れを防止でき、きれいに整列積層できるため、次工程での整列作業が容易となるようにしている。   That is, by providing the discharge unit lowering device 15, it is possible to achieve a moderate drop, to realize a good automatic lamination due to its own weight, and to keep this moderate drop by sequentially descending as the lamination height increases. Thus, rotation and direction disturbance due to a drop impact can be prevented, and neat alignment and lamination can be performed, so that alignment work in the next process is facilitated.

また、前記支承部8に対して前記切断可動部9を上下動自在に設け、この切断可動部9を下降させて前記支承部8から搬送方向に水平突出する前記フープ材1の送り突出部分を切断する際、フープ材1を支承部8に押さえ付ける押さえ付け部11をフープ材1上方に接離自在に設けている。   Further, the cutting movable portion 9 is provided so as to be movable up and down with respect to the support portion 8, and the feed movable portion of the hoop material 1 protruding horizontally from the support portion 8 in the conveying direction by lowering the cutting movable portion 9. When cutting, a pressing portion 11 for pressing the hoop material 1 against the support portion 8 is provided above and below the hoop material 1 so as to be freely contacted and separated.

具体的には、フープ材1上方に板状の押さえ付け部11を上下動自在に設け、この押さえ付け部11を送りローラ制御部10による送りローラ6の間欠駆動に同期させて下動させて、この押さえ付け部11により板状支承部8へフープ材1を押圧保持して切断する構成としている。   Specifically, a plate-like pressing portion 11 is provided above the hoop material 1 so as to be movable up and down, and the pressing portion 11 is moved downward in synchronization with the intermittent driving of the feed roller 6 by the feed roller control portion 10. The hoop material 1 is pressed and held on the plate-like support portion 8 by the pressing portion 11 and cut.

即ち、送りローラ6がプログラム制御されてフープ材1を間欠搬送し、所望の切断幅だけ支承部8より突出させ、これを切断可動部9を下動して切断する毎に、このタイミングに合わせてその切断直前には板状の押さえ付け部11も下動させて、板状の支承部8にフープ材1をこの押さえ付け部11で押さえ付けた状態として切断し、切断後再び離反し、送りローラ6による間欠搬送を再び行うように構成して、一層切断片1Aの切断幅の寸法精度が高まり高い寸法精度の積層材5(積層コア)を得ることができるようにしている。   That is, the feed roller 6 is program-controlled to intermittently convey the hoop material 1 so that it protrudes from the support portion 8 by a desired cutting width. The plate-like pressing part 11 is also moved down immediately before the cutting, and the hoop material 1 is cut to the plate-like support part 8 with the pressing part 11 being cut off. The intermittent conveyance by the feed roller 6 is performed again, so that the dimensional accuracy of the cutting width of the one-layer cut piece 1A is increased, and a laminated material 5 (laminated core) with high dimensional accuracy can be obtained.

また、本実施例では、送りローラ6の搬送上流側に、大型の積層コアを固定するための穴をフープ材1に開ける穴開け装置12を設けている。   Further, in the present embodiment, a punching device 12 that opens a hole for fixing a large laminated core in the hoop material 1 is provided on the upstream side of conveyance of the feed roller 6.

従って、必要に応じて積層コアを固定するために利用する穴を自動開口でき、この穴開け装置12はあくまで送り量をプログラム制御する送りローラ6よりも搬送上流側に配設するため、穴を開ける場合でも前記高い寸法精度を維持できる。また、この穴開け装置12による穴開けは、任意の位置に複数設けることも可能である。   Therefore, the holes used for fixing the laminated core can be automatically opened as necessary, and the hole punching device 12 is disposed on the upstream side of the feed roller 6 rather than the feed roller 6 that controls the feed amount. Even when opening, the high dimensional accuracy can be maintained. In addition, a plurality of holes can be provided by the hole punching device 12 at arbitrary positions.

更に説明すると、前述のように本実施例では、水平搬送ガイドする支承ローラ16(挟持ローラ16)と切断装置3の支承部8と間に、挟持ローラ16と対となってフープ材1の幅方向に架設しフープ材1を挟持し回動によってこのフープ材1を水平搬送させる前記送りローラ6を配設し、必要に応じてこの搬送手前側に金型パンチとダイとから成る前記穴開け装置12を配設している。   More specifically, as described above, in this embodiment, the width of the hoop material 1 is paired with the sandwiching roller 16 between the bearing roller 16 (the sandwiching roller 16) for guiding the horizontal conveyance and the support portion 8 of the cutting device 3. The feed roller 6 that is installed in the direction and sandwiches the hoop material 1 and horizontally transports the hoop material 1 by rotation is disposed, and the punching hole formed of a die punch and a die is provided on the front side of the transport if necessary. A device 12 is provided.

具体的には、本実施例では、帯幅100mm,板厚0.1mmのフープ材1(珪素鋼板)を送る装置としているが、本実施例では、前記支承部8から30mm〜300mmの範囲内となる程度に近接するように送りローラ6を配設している。   Specifically, in this embodiment, a device for feeding a hoop material 1 (silicon steel plate) having a band width of 100 mm and a plate thickness of 0.1 mm is used, but in this embodiment, within a range of 30 mm to 300 mm from the support portion 8. The feed roller 6 is disposed so as to be close to each other.

機械設計上近接するに限界はあるが、少なくとも本装置の場合、300mm以内となるように120mmの位置に送りローラ6を配設し切断装置3の支承部8に近づけている。   Although there is a limit in proximity in terms of mechanical design, at least in the case of this apparatus, the feed roller 6 is disposed at a position of 120 mm so as to be within 300 mm and is brought close to the support portion 8 of the cutting apparatus 3.

更にまた、この送りローラ6をステッピングモータやサーボモータとする回動精度の高い回動駆動源13により間欠回動することで、フープ材1の送り量のバラつきが0.02mm以内となる高い送り精度が実現できることが確認できた。   Furthermore, the feed roller 6 is intermittently rotated by a rotation drive source 13 having a high rotation accuracy using a stepping motor or a servo motor, so that the feed amount variation of the hoop material 1 is within 0.02 mm. It was confirmed that accuracy could be realized.

即ち、このように送りローラ6を近接することでフープ材1の歪みなどの影響が少なくなり、また回動精度、即ち送り精度の高い回動駆動源13を採用し、これをプログラム制御することで、この0.02mm以内の誤差範囲での送り量制御を実現でき、それ故この誤差範囲内で切断片1Aの切断幅が制御でき、高い寸法精度の積層材5を得ることができる。   That is, by bringing the feed roller 6 close in this way, the influence of distortion of the hoop material 1 is reduced, and the rotation drive source 13 with high rotation accuracy, that is, high feed accuracy is adopted, and this is program-controlled. Thus, the feed amount control within the error range within 0.02 mm can be realized. Therefore, the cutting width of the cut piece 1A can be controlled within the error range, and the laminated material 5 with high dimensional accuracy can be obtained.

更に具体的に説明すると、本実施例では、前述のように帯幅(積層材5の奥行幅)100mm,板厚0.1mmのフープ材1を切断した切断片1Aを252枚積層し、積層高さ25.2mmとしたもので、切断片1Aの最下板と最上板の切断幅が6.4mm,最も大きい中間部の切断幅25.3mm,この最大幅の25.3が60枚積層した同幅積層部分5Aを中間部に有する構成とし、この最大幅の切断片1Aから徐々に切断幅が増大若しくは減少するように切断して積層した略φ26の円柱構成としている。   More specifically, in this embodiment, as described above, 252 cut pieces 1A obtained by cutting the hoop material 1 having a band width (depth width of the laminated material 5) of 100 mm and a plate thickness of 0.1 mm are laminated and laminated. With a height of 25.2 mm, the cutting width of the lowermost plate and the uppermost plate of the cut piece 1A is 6.4 mm, the cutting width of the largest middle part is 25.3 mm, and the maximum width of 25.3 is laminated on 60 sheets The same width laminated portion 5A is formed in the middle portion, and a cylindrical structure of approximately φ26 is formed by cutting the laminated piece 1A from the maximum width so that the cutting width gradually increases or decreases.

そして、積層高さを検知する積層高さ測定部を備えて、板厚のバラつきや切断端縁のダレやバリなどによって積層高さに誤差が生じている場合は、例えばこれを見込んで同幅積層部分5A部分の積層枚数を調整設定するか、あるいは逐次除去調整するようにしている。   In addition, if there is a stack height measurement unit that detects the stack height, and there is an error in the stack height due to variations in plate thickness, sagging or burrs at the cutting edge, for example, this is expected to be the same width. The number of stacked layers in the stacked portion 5A is adjusted or set, or is removed and adjusted sequentially.

即ち、本実施例では、このように積層材5の積層高さ微調整のため前記送りローラ6の送り量を増減しないで一定幅の切断片1Aが積層されるように制御して積層材5の一部に同幅積層部分5Aを有するように前記送りローラ制御部10により制御する構成とし、例えば、積層材5をこのように積層形成する際、前記同幅積層部分5Aの枚数を調整制御又は前記排出部4に積層形成された前記同幅積層部分5Aの切断片1Aを除去若しくは付加して積層材5の積層高さを所定値とするようにしている。   That is, in the present embodiment, in order to finely adjust the stacking height of the laminate 5 in this manner, the laminate 5 is controlled by controlling the cut pieces 1A having a constant width without increasing or decreasing the feed amount of the feed roller 6. The feed roller control unit 10 controls so as to have the same width laminated portion 5A in a part of, for example, when the laminated material 5 is laminated in this way, the number of the same width laminated portion 5A is adjusted and controlled. Alternatively, the cut height 1A of the laminated portion 5A having the same width formed on the discharge portion 4 is removed or added so that the laminated height of the laminated material 5 is set to a predetermined value.

また、前記積層材5を製造する際、前記排出部4に短冊状の切断片1Aが積層形成された積層材5の一の積層部分を他の積層部分に対して表裏反転させて積層し表裏向きが異なる部分を有する積層材5とするようにしている。   Further, when the laminated material 5 is manufactured, one laminated portion of the laminated material 5 in which the strip-shaped cut pieces 1A are laminated and formed on the discharge portion 4 is reversed with respect to the other laminated portions and laminated. The laminated material 5 has portions having different directions.

即ち、積層形成し終えた積層材5の一部を他の一部に比して束にして表裏反転させて組み直し積層整列させ、次工程に送っても良いが、本実施例では、前記送りローラ6の送り量が徐々に増加するように制御して側面視略半円形の積層材5を順次形成し、この二つの積層材5を一方を上下逆向きにして合せ略円形の積層材5を得ることで、上半分と下半分とが表裏向きが異なるように積層された側面視略円形の積層材5となるようにしている。   That is, a part of the laminated material 5 that has been laminated and formed may be bundled as compared with the other part, turned upside down, reassembled, laminated and aligned, and sent to the next process. By controlling the feed amount of the roller 6 to gradually increase, a substantially semi-circular laminated material 5 is formed in sequence, and the two laminated materials 5 are turned upside down so that the substantially circular laminated material 5 is aligned. Thus, the upper half and the lower half are made to have a substantially circular laminated material 5 that is laminated so that the front and back directions are different from each other.

このようにすることで、同幅寸法の切断片1Aが積層されることで切断縁でダレやバリが生じていても片寄りなくきれいに積層でき、積層高さの管理も良好となり一層寸法精度の高い積層コアを得ることができる。   By doing this, the cut pieces 1A having the same width can be laminated, so that even if the cut edge has a sag or burr, it can be laminated neatly without misalignment, the management of the stacking height can be improved, and the dimensional accuracy can be further improved. A high laminated core can be obtained.

尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。   The present invention is not limited to the present embodiment, and the specific configuration of each component can be designed as appropriate.
