Description

熱交換器用フィンの製造装置Production equipment for heat exchanger fins
　本発明は、複数の透孔または複数の切欠部を有する熱交換器用フィンを製造する熱交換器用フィンの製造装置に関する。 The present invention relates to a heat exchanger fin manufacturing apparatus for manufacturing a heat exchanger fin having a plurality of through holes or a plurality of notches.
　従来のクーラー等の熱交換器は、熱交換チューブを挿入する透孔が複数個穿設された熱交換器用フィンが複数枚積層されて構成されているものが一般的である。
　かかる熱交換器用フィンは、図８に示すような熱交換器用フィンの製造装置１によって製造することができる（特許文献１参照）。
　熱交換器用フィンの製造装置１には、アルミニウム等の金属製の薄板１０がコイル状に巻かれたアンコイラー１２が設けられている。アンコイラー１２からピンチロール１４を経て引き出された薄板１０は、オイル付与装置１６に挿入され、薄板１０の表面に加工用オイルを付着させた後、プレス装置１８内に設けられた金型装置２０に供給される。 Conventional heat exchangers such as coolers are generally configured by laminating a plurality of heat exchanger fins each having a plurality of through holes into which heat exchange tubes are inserted.
Such heat exchanger fins can be manufactured by a heat exchanger fin manufacturing apparatus 1 as shown in FIG. 8 (see Patent Document 1).
The heat exchanger fin manufacturing apparatus 1 is provided with an uncoiler 12 in which a thin metal plate 10 such as aluminum is wound in a coil shape. The thin plate 10 drawn from the uncoiler 12 through the pinch roll 14 is inserted into the oil applying device 16, and after processing oil is attached to the surface of the thin plate 10, the thin plate 10 is applied to the mold device 20 provided in the press device 18. Supplied.
　金型装置２０は、内部に上下動可能な上型ダイセット２２と、静止状態にある下型ダイセット２４とが設けられている。この金型装置２０によって、透孔の周囲に所定高さのカラーが形成された複数個のカラー付き透孔（図示せず）が所定の方向に所定の間隔（マトリクス状配列）で形成される。以下、金属製の薄板に透孔等が加工されたものを、金属帯状体１１と称する。 The mold apparatus 20 is provided with an upper die set 22 that can move up and down and a lower die set 24 that is stationary. By this mold apparatus 20, a plurality of collared through holes (not shown) in which a collar having a predetermined height is formed around the through holes are formed at predetermined intervals (matrix-like arrangement) in a predetermined direction. . Hereinafter, a metal thin plate in which through holes and the like are processed is referred to as a metal strip 11.
　ここで加工された金属帯状体１１は、製品となる熱交換器用フィンが幅方向に複数配列された状態で形成されている。このため、金型装置２０の下流位置には、列間スリット装置２５が設けられている。列間スリット装置２５は、第１送り装置２６により間欠送りされる金属帯状体１１を、噛み合わせた上刃２５Ａと下刃２５Ｂとで切断し、搬送方向に長い帯状の製品幅の金属帯状体１１Ａを形成するものである。 The processed metal strip 11 is formed in a state in which a plurality of heat exchanger fins that are products are arranged in the width direction. For this reason, an inter-row slit device 25 is provided at a downstream position of the mold device 20. The inter-row slit device 25 cuts the metal strip 11 intermittently fed by the first feeding device 26 with the upper blade 25A and the lower blade 25B engaged with each other, and has a long strip-like product width metal strip. 11A is formed.
　製品幅の金属帯状体１１Ａは、カッター２７によって所定長さに切断され、製造目的品である熱交換器用フィン１３に形成される。熱交換器用フィン１３はスタッカ２８に収容される。スタッカ２８には、鉛直方向に複数のピン２９が立設されている。熱交換器用フィン１３は熱交換器用フィン１３に形成された透孔内にピン２９を挿入されることによりスタッカ２８に積層保持される。 The metal strip 11A having a product width is cut into a predetermined length by the cutter 27 and formed on the heat exchanger fin 13 which is a manufacturing object. The heat exchanger fins 13 are accommodated in the stacker 28. A plurality of pins 29 are erected on the stacker 28 in the vertical direction. The heat exchanger fins 13 are stacked and held on the stacker 28 by inserting pins 29 into the through holes formed in the heat exchanger fins 13.

　従来の熱交換器用フィン１３は、金属帯状体１１に熱交換チューブが挿入される複数の透孔が穿設されたものであった。
　しかしながら現在、多穴の扁平チューブを用いた熱交換器が流通している。この扁平チューブを用いた熱交換器用フィンを図９Ａおよび図９Ｂに示す。 The conventional heat exchanger fin 13 has a plurality of through holes into which the heat exchange tube is inserted into the metal strip 11.
However, currently, heat exchangers using multi-hole flat tubes are in circulation. A heat exchanger fin using this flat tube is shown in FIGS. 9A and 9B.
　熱交換器用フィン３０は、扁平チューブ３２が挿入されるチューブ挿入部３４が所要の間隔をあけて複数形成されており、チューブ挿入部３４とチューブ挿入部３４との間は、ルーバー３５が形成された板状部３６が形成されている。
　チューブ挿入部３４は、熱交換器用フィン３０の幅方向の一方側からのみ形成されている。したがって、チューブ挿入部３４とチューブ挿入部３４との間の複数の板状部３６は、長手方向に沿って伸びる連結部３８によって連結されている。なお、切り起し部３７は、熱交換器用フィン３０を積層させる際において、上下の熱交換器用フィン３０，３０に隙間を形成するためのものである。 In the heat exchanger fin 30, a plurality of tube insertion portions 34 into which the flat tubes 32 are inserted are formed at a predetermined interval, and a louver 35 is formed between the tube insertion portion 34 and the tube insertion portion 34. A plate-like portion 36 is formed.
The tube insertion portion 34 is formed only from one side in the width direction of the heat exchanger fin 30. Accordingly, the plurality of plate-like portions 36 between the tube insertion portion 34 and the tube insertion portion 34 are connected by a connection portion 38 extending along the longitudinal direction. The cut-and-raised portion 37 is used to form a gap in the upper and lower heat exchanger fins 30 and 30 when the heat exchanger fins 30 are stacked.
　ところで、熱交換器用フィンを製造する製造装置における、製品幅の金属帯状体を所定長さに切断して製品である熱交換器用フィンを形成するカットオフ装置では、製品の長さを任意に変更できるように、列間スリット装置における製品幅の金属帯状体の１回（型閉じ１回）の送り長さよりも、カットオフ1回の送り長さを長くすることができる。
　このため、列間スリット装置とカットオフ装置との間では、カットオフ装置による１回の送り長さよりも長い長さを一時的に溜めるため、製品幅の金属帯状体を下方にたるませておくことがある。 By the way, in a manufacturing apparatus for manufacturing heat exchanger fins, in a cut-off device that forms a heat exchanger fin as a product by cutting a metal strip having a product width into a predetermined length, the length of the product is arbitrarily changed. As can be done, the feed length of one cut-off can be made longer than the feed length of one time (one mold closing) of the metal strip having the product width in the inter-row slit device.
For this reason, between the inter-row slit device and the cut-off device, in order to temporarily accumulate a length longer than a single feed length by the cut-off device, the metal strip having the product width is slacked downward. Sometimes.
　このように製品幅の金属帯状体を下方にたるませた場合、製品幅の金属帯状体が間欠送りされることによって製品幅の金属帯状体が揺動し、隣接する製品幅の金属帯状体どうしが絡んでしまうことがある。これを防止するために製品幅の金属帯状体の下方へのたるみ状態を管理するため制御部を有する熱交換器用フィンの製造装置の構成が特許文献２に開示されている。 In this way, when the metal strip of the product width is slackened downward, the metal strip of the product width swings by intermittently feeding the metal strip of the product width, and the metal strips of the product width adjacent to each other. May get tangled. In order to prevent this, Patent Document 2 discloses a configuration of a heat exchanger fin manufacturing apparatus having a control unit for managing the state of slacking downward of a metal strip having a product width.
　しかしながら、特許文献２に開示されている制御部の構成は制御内容が複雑であることもあり、このような制御部を採用した熱交換器用フィンの製造装置は提供コストが高価になるという課題がある。
　このような高価な制御部を採用せずに製品幅の金属帯状体の絡みを防止すべく、製品幅の金属帯状体どうしを離反させようとすると、熱交換器用フィンの製造装置が大型になってしまい、工場の単位面積当たりにおける熱交換器用フィンの製造量が低下してしまい、熱交換器用フィンの製造コストの低減が阻害されるといった課題もある。 However, the configuration of the control unit disclosed in Patent Document 2 may have complicated control contents, and the heat exchanger fin manufacturing apparatus employing such a control unit has a problem that the provision cost is expensive. is there.
If the product width metal strips are separated from each other in order to prevent the product width metal strips from becoming entangled without using such an expensive control unit, the heat exchanger fin manufacturing apparatus becomes large. As a result, the production amount of the heat exchanger fins per unit area of the factory is reduced, and there is a problem that reduction of the production cost of the heat exchanger fins is hindered.
　そこで本発明は上記課題を解決すべくなされ、その目的とするところは、安価でしかも小型でありながらも、製品幅の金属帯状体どうしを下方にたるませた状態で間欠送りしても、製品幅の金属帯状体どうしが絡まないようにすることが可能な熱交換器用フィンの製造装置を提供することにある。 Therefore, the present invention has been made to solve the above-mentioned problems, and the object of the present invention is to provide a product that is inexpensive and small in size, but can be intermittently fed while the metal strips of the product width are slackened downward. An object of the present invention is to provide a heat exchanger fin manufacturing apparatus capable of preventing the metal strips having a width from being entangled with each other.
　出願人は、上記課題を解決するため鋭意研究をした結果、課題を解決することが可能な構成に想到した。
　すなわち、本発明は、複数の透孔又は複数の切り欠き部を有する金属帯状体を形成する金型装置と、該金属帯状体を列方向に切断し、当該列方向に複数本整列してなる製品幅の金属帯状体を形成する列間スリット装置と、前記列間スリット装置によって形成された製品幅の金属帯状体を下流側に送る第１送り装置と、を備えたプレス装置を具備する熱交換器用フィンの製造装置であって、前記列間スリット装置によって形成された複数本の製品幅の金属帯状体のそれぞれを所定長さに切断する切断装置と、前記列間スリット装置によって形成された複数本の製品幅の金属帯状体のそれぞれを前記切断装置へ送り込む第２送り装置と、を有するカットオフ装置を具備し、前記列間スリット装置から出た複数本の製品幅の金属帯状体は、下方にたるませた状態を経てから前記カットオフ装置に進入するように設けられ、前記列間スリット装置の送り出し位置と、前記カットオフ装置への進入位置との間には、隣接する製品幅の金属帯状体のたるみ開始位置又はたるみ終了位置を異ならせるために、それぞれの製品幅の金属帯状体の下面を支持し、製品幅の金属帯状体の送り方向における突出長さが隣接する製品幅の金属帯状体の間で異なる複数の受け部を具備することを特徴とする。 As a result of diligent research to solve the above problems, the applicant has come up with a configuration that can solve the problems.
That is, the present invention comprises a mold apparatus for forming a metal strip having a plurality of through holes or a plurality of notches, and the metal strip is cut in a row direction and aligned in the row direction. Heat provided with a pressing device comprising: an inter-row slit device for forming a metal strip having a product width; and a first feeding device for feeding the metal strip having a product width formed by the inter-row slit device to the downstream side. An apparatus for manufacturing a fin for an exchanger, which is formed by a cutting device for cutting each of a plurality of metal strips having a product width formed by the inter-row slit device into a predetermined length, and the inter-row slit device. A plurality of product-width metal strips, each having a cut-off device having a second feeding device that feeds each of the product-width metal strips to the cutting device. Down A metal strip having an adjacent product width between the feed position of the inter-row slit device and the entry position to the cut-off device. In order to make the sagging start position or sagging end position different, the lower surface of the metal strip of each product width is supported, and the projecting length in the feeding direction of the metal strip of the product width is adjacent to the metal strip of the product width It is characterized by comprising a plurality of receiving portions that are different from each other.
　本構成を採用することによって、安価でありかつ小型で簡易な構成でありながらも互いに隣接する製品幅の金属帯状体どうしが絡まない程度に離反させた状態で列間スリット装置からカットオフ装置に製品幅の金属帯状体を送り出すことが可能な熱交換器用フィンの製造装置を提供することができる。 By adopting this configuration, it is an inexpensive, small, and simple configuration, but it is separated from the inter-column slit device into the cut-off device in a state where the metal strips of the product widths adjacent to each other are separated from each other. The manufacturing apparatus of the fin for heat exchangers which can send out the metal strip of a product width can be provided.
　また、前記受け部は、前記列間スリット装置の送り出し位置、および、前記カットオフ装置への進入位置のうちの少なくとも一方に配設されていることが好ましい。 Further, it is preferable that the receiving portion is disposed at at least one of a delivery position of the inter-row slit device and an entry position to the cutoff device.
　この構成によれば、必要最小限の簡易な構成を付加するだけで、互いに隣接する製品幅の金属帯状体どうしが絡まない程度に離反させた状態で列間スリット装置からカットオフ装置に製品幅の金属帯状体を下方にたるませた状態で送り出すことが可能になる。 According to this configuration, the product width is changed from the inter-row slit device to the cut-off device in such a state that the metal strips of the product width adjacent to each other are separated from each other only by adding the minimum necessary simple configuration. It is possible to send out the metal strip in a state where it is slackened downward.
　また、前記受け部は、前記列間スリット装置から送り出された前記製品幅の金属帯状体の下方へのたるみ開始位置、および、前記カットオフ装置に進入する前記製品幅の金属帯状体の下方へのたるみからの復元位置のうちの少なくとも一方が調整可能に形成されていることが好ましい。 In addition, the receiving portion starts to sag downward from the metal strip having the product width fed from the inter-row slit device, and below the metal strip having the product width entering the cut-off device. It is preferable that at least one of the restoration positions from the slack is formed to be adjustable.
　これにより、製品幅の金属帯状体の形状等に応じて、列間スリット装置とカットオフ装置との間における製品幅の金属帯状体の下方へのたるみ状態を適宜調整することができる。よって、列間スリット装置とカットオフ装置との間における製品幅の金属帯状体の下方へのたるみ部分における絡み合いのおそれがなく、製品の生産性が向上する。 Thereby, according to the shape of the metal strip having the product width, the slack state of the metal strip having the product width between the inter-row slit device and the cutoff device can be appropriately adjusted. Therefore, there is no fear of entanglement in the downward slack portion of the metal strip of the product width between the inter-row slit device and the cut-off device, and the product productivity is improved.
　本発明によれば、熱交換器用フィンの製造装置を小型化しても列間スリット装置から送り出された後に下方にたるませた製品幅の金属帯状体どうしが絡まないようにした熱交換器用フィンの製造装置を安価に提供することができる。 According to the present invention, even if the heat exchanger fin manufacturing apparatus is downsized, the heat exchanger fins are configured so that the metal strips of the product width that are slackened downward after being fed out from the inter-row slit apparatus are not entangled. A manufacturing apparatus can be provided at low cost.

　本実施形態にかかる熱交換器用フィンの製造装置の全体構成を図１に示す。
　アルミニウム等の未加工の金属製の薄板４１は、アンコイラー４０にコイル状に巻回されている。アンコイラー４０から引き出された薄板４１は、ループコントローラ４２内に挿入され、間欠送りされる薄板４１のばたつきがループコントローラ４２によって抑えられる。 (First embodiment)
FIG. 1 shows the overall configuration of a heat exchanger fin manufacturing apparatus according to the present embodiment.
An unprocessed metal thin plate 41 such as aluminum is wound around an uncoiler 40 in a coil shape. The thin plate 41 pulled out from the uncoiler 40 is inserted into the loop controller 42, and fluttering of the thin plate 41 that is intermittently fed is suppressed by the loop controller 42.
　ループコントローラ４２の下流側には、ＮＣフィーダ４４が設けられている。ＮＣフィーダ４４は、薄板４１の上面と下面とに接触する２つのローラから構成されており、２つのローラが回転駆動することにより、薄板４１を互いに挟み込んで薄板４１を間欠送りする。
　ＮＣフィーダ４４の下流側には、金型装置４６が内部に配置されたプレス装置４７が設けられている。本実施形態の金型装置４６は、上型ダイセット４６Ａと下型ダイセット４６Ｂとを有し、上型ダイセット４６Ａまたは下型ダイセット４６Ｂの一方が他方に対して接離動可能に設けられている。プレス装置４７において、薄板４１が金型装置４６によって所定の形状の金属帯状体４８に形成される。 An NC feeder 44 is provided on the downstream side of the loop controller 42. The NC feeder 44 is composed of two rollers that are in contact with the upper surface and the lower surface of the thin plate 41. When the two rollers are driven to rotate, the thin plate 41 is sandwiched between each other to intermittently feed the thin plate 41.
On the downstream side of the NC feeder 44, a press device 47 in which a mold device 46 is disposed is provided. The mold apparatus 46 of the present embodiment has an upper die set 46A and a lower die set 46B, and one of the upper die set 46A and the lower die set 46B is provided so as to be movable toward and away from the other. It has been. In the pressing device 47, the thin plate 41 is formed into a metal strip 48 having a predetermined shape by the mold device 46.
　ここで形成される金属帯状体４８を図２に示す。
　図２に示す金属帯状体４８は、搬送方向（図２内の横方向の矢印）に直交する幅方向（図２内の縦方向の矢印）に４列の製品群が並んで形成されている。金属帯状体４８を個片化して得られる各々の製品については、図９Ａおよび図９Ｂを参照して説明するが、扁平チューブ３２が挿入されるチューブ挿入部３４が複数箇所に形成されており、チューブ挿入部３４とチューブ挿入部３４との間は、ルーバー３５が形成された板状部３６が形成されている。また、ルーバー３５の幅方向の両端部側には、板状部３６の一部が切り起こされて形成された切り起し部３７が形成されている。１つのルーバー３５に対する２つの切り起し部３７，３７のうち、一方側の切り起し部３７は、板状部３６の先端部側に形成されている。 The metal strip 48 formed here is shown in FIG.
The metal strip 48 shown in FIG. 2 is formed by arranging four rows of product groups in the width direction (vertical arrow in FIG. 2) orthogonal to the transport direction (horizontal arrow in FIG. 2). . Each product obtained by dividing the metal strip 48 into individual pieces will be described with reference to FIGS. 9A and 9B, and the tube insertion portions 34 into which the flat tubes 32 are inserted are formed at a plurality of locations. Between the tube insertion part 34 and the tube insertion part 34, the plate-shaped part 36 in which the louver 35 was formed is formed. Further, on both ends of the louver 35 in the width direction, cut and raised portions 37 formed by cutting and raising a part of the plate-like portion 36 are formed. Of the two raised portions 37, 37 with respect to one louver 35, the one raised portion 37 is formed on the distal end side of the plate-like portion 36.
　チューブ挿入部３４は、熱交換器用フィン３０の幅方向の一方側からのみ形成されている。したがって、チューブ挿入部３４とチューブ挿入部３４との間の複数の板状部３６は、長手方向に沿って伸びる連結部３８によって連結されている。
　上記の１つのルーバー３５に対する２つの切り起し部３７，３７のうち、他方側の切り起し部３７は、この連結部３８上に形成されている。 The tube insertion portion 34 is formed only from one side in the width direction of the heat exchanger fin 30. Accordingly, the plurality of plate-like portions 36 between the tube insertion portion 34 and the tube insertion portion 34 are connected by a connection portion 38 extending along the longitudinal direction.
Of the two raised portions 37, 37 for the one louver 35, the other raised portion 37 is formed on the connecting portion 38.
　図２に示す金属帯状体４８は、２つの製品が、互いのチューブ挿入部３４の開口側が隣接するように向い合わせた状態で配置されている組が、２組形成されている。すなわち、２つの製品のチューブ挿入部３４の開口側が対向して配置された組が、互いの連結部３８が隣接するように配置されている。
　このように、４つの製品を相対するように配置することによって、金型装置４６および金属帯状体４８の左右の荷重バランスが良くなる。 The metal strip 48 shown in FIG. 2 is formed of two sets in which two products are arranged so that the opening sides of the tube insertion portions 34 face each other. That is, a set in which the opening sides of the tube insertion portions 34 of the two products are opposed to each other is arranged so that the connecting portions 38 are adjacent to each other.
Thus, by arranging the four products so as to face each other, the left and right load balance between the mold device 46 and the metal strip 48 is improved.
　なお、図２のような金属帯状体４８と異なり、複数の製品のチューブ挿入部３４の開口側が全て一方方向に向いて配置させてしまうと、各製品群を切り離す列間スリット装置５２（後述する）によって各製品間を切り離す際に、チューブ挿入部３４とそうでない部位との間で、切断位置のずれによる切断片（ヒゲ：切断不良）が生じてしまう可能性が高い。したがって、複数の製品のチューブ挿入部３４の開口側が全て一方方向に向いて配置させる場合には、チューブ挿入部３４の開口部の境目ではなく、連結部３８部分に進入した位置までチューブ挿入部３４の開口部分を若干広げ、切断させる必要が出てくる。しかし、この場合だと断面に段差が生じてしまうし、また金型の左右の荷重バランスが悪くなる。したがって、図２に示したような配置で複数の製品を製造することが好ましいのである。 In addition, unlike the metal strip 48 shown in FIG. 2, if all the opening sides of the tube insertion portions 34 of a plurality of products are arranged in one direction, the inter-row slit device 52 (described later) that separates each product group. ), When cutting between the products, there is a high possibility that a cut piece (whisker: cutting failure) due to a shift in the cutting position will occur between the tube insertion portion 34 and the portion that is not. Accordingly, when all of the opening sides of the tube insertion portions 34 of the plurality of products are arranged in one direction, the tube insertion portion 34 is not located at the boundary of the opening portion of the tube insertion portion 34 but to the position where it enters the connecting portion 38 portion. It becomes necessary to slightly widen and cut the opening. However, in this case, a step is generated in the cross section, and the left and right load balance of the mold is deteriorated. Therefore, it is preferable to manufacture a plurality of products in the arrangement as shown in FIG.
　製造装置の全体構成の説明に戻る。
　プレス装置４７内の金型装置４６で形成された金属帯状体４８は、プレス装置４７の下流側に設けられている第１送り装置５０によって間欠的に搬送方向に送られる。第１送り装置５０の送りタイミングは、ＮＣフィーダ４４と連動して動作するように設けられており、安定した間欠送りを可能とする。 Returning to the description of the overall configuration of the manufacturing apparatus.
The metal strip 48 formed by the mold device 46 in the press device 47 is intermittently fed in the transport direction by the first feeding device 50 provided on the downstream side of the press device 47. The feed timing of the first feeding device 50 is provided so as to operate in conjunction with the NC feeder 44, and enables stable intermittent feeding.
　第１送り装置５０は、水平方向に移動可能な往復動ユニット５１が、初期位置と移送位置との間を往復動して金属帯状体４８を牽引する。往復動ユニット５１の上面には、送りピン５５が上方に突出して配置されており、送りピン５５が金属帯状体４８に形成されたチューブ挿入部３４内に下方から進入し、送りピン５５が牽引することで金属帯状体４８は移送位置まで移動する。 In the first feeding device 50, a reciprocating unit 51 that is movable in the horizontal direction reciprocates between an initial position and a transfer position to pull the metal strip 48. A feed pin 55 is disposed on the upper surface of the reciprocating unit 51 so as to protrude upward. The feed pin 55 enters the tube insertion portion 34 formed in the metal strip 48 from below, and the feed pin 55 is pulled. As a result, the metal strip 48 moves to the transfer position.
　第１送り装置５０の下流側には、列間スリット装置５２が設けられている。列間スリット装置５２は、金属帯状体４８の上面側に配置された上刃５３と、金属帯状体４８の下面側に配置された下刃５４とを有する。列間スリット装置５２は、プレス装置４７の上下動動作を利用して動作するように設けるとよい。
　上刃５３及び下刃５４は、金属帯状体４８の搬送方向に長尺に形成されており、間欠送りされる金属帯状体４８を、噛み合わせた上刃５３と下刃５４とで切断し、搬送方向に長い製品の中間体である製品幅の金属帯状体４９に形成する。 An inter-row slit device 52 is provided on the downstream side of the first feeding device 50. The inter-row slit device 52 includes an upper blade 53 disposed on the upper surface side of the metal strip 48 and a lower blade 54 disposed on the lower surface side of the metal strip 48. The inter-row slit device 52 may be provided so as to operate using the vertical movement operation of the press device 47.
The upper blade 53 and the lower blade 54 are formed long in the conveying direction of the metal strip 48, and the intermittently fed metal strip 48 is cut by the meshed upper blade 53 and lower blade 54, It is formed on a metal strip 49 having a product width, which is an intermediate product that is long in the conveying direction.
　列間スリット装置５２によって製品幅に切断された、複数本の製品幅の金属帯状体４９は、カットオフ装置６０内に送り込まれる。
　なお、カットオフ装置６０に送り込まれる前に、複数本（本実施形態では４本）の製品幅の金属帯状体４９は、隣り合う製品幅の金属帯状体４９どうしの間を所定間隔（後述するスタック装置の構造にもよるが、５～１０ｍｍ程度）あけるように配置される。また、カットオフ装置６０に送り込まれる前には、複数本の製品幅の金属帯状体４９は、カットオフ装置６０による１回の送り長さよりも長い長さを一時的に溜めるため、下方にたるませるようにしている（図１中のＡ部分および図３参照）。 The metal strips 49 having a plurality of product widths cut into the product width by the inter-row slit device 52 are fed into the cut-off device 60.
In addition, before being sent to the cut-off device 60, a plurality (four in the present embodiment) of the metal strips 49 having the product width are spaced by a predetermined interval (described later). Depending on the structure of the stacking device, it is arranged so as to be open about 5-10 mm. In addition, before being fed into the cut-off device 60, the metal strips 49 having a plurality of product widths are stored in a length longer than a single feed length by the cut-off device 60. This is done (see portion A in FIG. 1 and FIG. 3).
　先述にあるように、製品幅の金属帯状体４９は搬送方向に水平側に直交する方向（幅方向）における重量バランスが搬送方向の中心線に対して対称になっていない。このため、製品幅の金属帯状体４９を下方にたるませた状態で、製品幅の金属帯状体４９を間欠送りしようとすると、下方にたるませた部分で製品幅の金属帯状体４９が揺動し、隣接する製品幅の金属帯状体４９が絡まってしまうおそれがある。そこで、図１に示すように列間スリット装置５２の送り出し位置（製品幅の金属帯状体４９の搬送方向における下流端位置）に、受け部５６を配設することにより、たるみ位置における製品幅の金属帯状体４９の絡まりを防止している。 As described above, in the metal strip 49 having the product width, the weight balance in the direction (width direction) orthogonal to the horizontal side in the transport direction is not symmetric with respect to the center line in the transport direction. For this reason, if the product-width metal strip 49 is intermittently fed in a state where the product-width metal strip 49 is slacked downward, the product-width metal strip 49 swings in the slacked portion. Then, there is a possibility that the adjacent metal strips 49 having the product width will be entangled. Therefore, as shown in FIG. 1, the receiving portion 56 is disposed at the delivery position of the inter-row slit device 52 (the downstream end position in the conveying direction of the metal strip 49 of the product width), thereby reducing the product width at the slack position. The tangling of the metal strip 49 is prevented.
　本実施形態における受け部５６は、列間スリット装置５２により複数本に分割された製品幅の金属帯状体４９の送り出し位置にそれぞれ対応させた状態で配設されている。受け部５６は、その上面高さ位置が列間スリット装置５２における製品幅の金属帯状体４９の搬送面高さ位置に擦り付けられると共に、列間スリット装置５２からカットオフ装置６０側に向って突出するようにして延設されている。このような受け部５６を採用することにより、列間スリット装置５２から送り出される製品幅の金属帯状体４９の下面を支持した状態でカットオフ装置６０に向けて製品幅の金属帯状体４９をガイドすることができる。 The receiving portion 56 in the present embodiment is disposed in a state corresponding to the delivery position of the metal strip 49 having a product width divided into a plurality of pieces by the inter-row slit device 52. The receiving portion 56 is rubbed against the conveying surface height position of the metal strip 49 having the product width in the inter-row slit device 52 and protrudes from the inter-row slit device 52 toward the cut-off device 60 side. It is extended like this. By adopting such a receiving portion 56, the product-width metal strip 49 is guided toward the cut-off device 60 in a state where the lower surface of the product-width metal strip 49 fed from the inter-row slit device 52 is supported. can do.
　より詳細には、図１，図３に示すように、受け部５６は上側に凸をなす湾曲形状に形成されている。このような形状の受け部５６を採用することにより、製品幅の金属帯状体４９が自重により急激に下方にたるむことがなく、製品幅の金属帯状体４９に意図しない屈曲部が形成されることを防止することができる。 More specifically, as shown in FIGS. 1 and 3, the receiving portion 56 is formed in a curved shape that protrudes upward. By adopting the receiving portion 56 having such a shape, the metal strip 49 having the product width does not sag suddenly due to its own weight, and an unintended bent portion is formed in the metal strip 49 having the product width. Can be prevented.
　ここで、受け部５６は、列間スリット装置５２からの製品幅の金属帯状体４９が搬送される方向における下流端位置に対して着脱可能であることが好ましい。このような着脱形態としては、ねじなどの締結手段や磁石を用いた着脱構造を採用することができる。また、受け部５６は、列間スリット装置５２から受け部５６の先端位置までの長さが調整可能であることがさらに好ましい。このような受け部５６の長さ調整を可能にする構成としては、長さ寸法の異なる複数の受け部５６を準備する他、釣竿や三脚等において採用されている引き伸ばし構造等を採用することができる。 Here, the receiving portion 56 is preferably detachable from the downstream end position in the direction in which the metal strip 49 having the product width from the inter-row slit device 52 is conveyed. As such an attaching / detaching form, an attaching / detaching structure using a fastening means such as a screw or a magnet can be adopted. Further, it is more preferable that the length of the receiving portion 56 from the inter-row slit device 52 to the tip position of the receiving portion 56 can be adjusted. As a configuration that makes it possible to adjust the length of the receiving portion 56, in addition to preparing a plurality of receiving portions 56 having different length dimensions, it is possible to adopt a stretching structure or the like that is used in a fishing rod, tripod, or the like. it can.
　ところで、本実施形態においては、図１および図３に示すように列間スリット装置５２から送り出される製品幅の金属帯状体４９のうち第１列目および第３列目に対応させた受け部５６と、同じく第２列目と第４列目に対応させた受け部５６との列間スリット装置５２からの突出量を異ならせている。より具体的には、第１列目および第３列目の製品幅の金属帯状体４９に対応させた受け部５６の突出量よりも、第２列目および第４列目の製品幅の金属帯状体４９に対応させた受け部５６の突出量の方が多くなるようにした。 By the way, in this embodiment, as shown in FIG. 1 and FIG. 3, the receiving part 56 corresponding to the 1st row | line and the 3rd row | line | column among the metal strip | belt bodies 49 of the product width sent out from the slit apparatus 52 between rows | lines. Similarly, the protruding amounts from the inter-row slit device 52 of the receiving portions 56 corresponding to the second row and the fourth row are made different. More specifically, the metal of the product width of the second row and the fourth row is larger than the protruding amount of the receiving portion 56 corresponding to the metal strip 49 of the product width of the first row and the third row. The amount of protrusion of the receiving portion 56 corresponding to the belt-like body 49 is increased.
　列間スリット装置５２から送り出される４本の製品幅の金属帯状体４９は、列間スリット装置５２からの受け部５６の突出量を異ならせていることにより、第１列目および第３列目と、第２列目および第４列目と、において、列間スリット装置５２から離反した後における下方へのたるみ状態が相違することになる。 The metal strips 49 having the four product widths sent out from the inter-row slit device 52 have different projection amounts of the receiving portions 56 from the inter-row slit device 52, so that the first row and the third row. In the second row and the fourth row, the state of sagging downward after separating from the inter-row slit device 52 is different.
　すなわち、列間スリット装置５２からの突出量が多い受け部５６が取り付けられている第２列目と第４列目の製品幅の金属帯状体４９は、列間スリット装置５２の搬送方向の下流端位置から受け部５６の上面に沿って所要距離にわたり水平方向に搬送された後、自重により下方に略Ｕ字状をなしてたるむことになる。これに対して列間スリット装置５２からの突出量が少ない第１列目と第３列目の製品幅の金属帯状体４９は、第２列目と第４列目の製品幅の金属帯状体４９の下方へのたるみ開始位置よりも列間スリット装置５２側の位置で下方にたるみはじめることになる。 That is, the metal strips 49 having the product widths in the second row and the fourth row to which the receiving portions 56 having a large amount of protrusion from the inter-row slit device 52 are attached are downstream of the inter-row slit device 52 in the transport direction. After being transported in the horizontal direction over the required distance along the upper surface of the receiving portion 56 from the end position, it will sag in a substantially U shape downward due to its own weight. On the other hand, the metal strips 49 having the product width in the first row and the third row with a small amount of protrusion from the inter-row slit device 52 are the metal strips having the product width in the second row and the fourth row. 49 starts to sag downward at a position closer to the inter-row slit device 52 than the sag starting position of 49 below.
　ところで、列間スリット装置５２から送り出される製品幅の金属帯状体４９は、各列において同一長さである。すなわち、第２列および第４列における製品幅の金属帯状体４９による下方側たるみ部分の下側頂点位置と、第１列および第３列における製品幅の金属帯状体４９による下方側たるみ部分の下側頂点位置とで高さが異なることにもなる。 By the way, the product-width metal strips 49 fed from the inter-row slit device 52 have the same length in each row. That is, the lower apex position of the lower slack portion due to the product width metal strip 49 in the second row and the fourth row, and the lower slack portion due to the product width metal strip 49 in the first row and the third row The height is also different from the lower vertex position.
　換言すると、列間スリット装置５２からの受け部５６の突出量の相違により、図１，図３に示すように製品幅の金属帯状体４９の下方へのたるみ開始位置と下側頂点の高さ位置（Ｕ字状をなしたたるみ変形部分における縦横のアスペクト比）を異ならせることができる。 In other words, due to the difference in the protruding amount of the receiving portion 56 from the inter-row slit device 52, as shown in FIGS. 1 and 3, the downward slack start position of the product-width metal strip 49 and the height of the lower apex are shown. The position (vertical / horizontal aspect ratio in the sagging deformation portion having a U-shape) can be varied.
　このように、列間スリット装置５２に対する受け部５６の突出量の相違により、列間スリット装置５２とカットオフ装置６０との間において、水平方向に隣接する製品幅の金属帯状体４９を水平（幅）方向および鉛直（高さ）方向にそれぞれずらした状態にすることができる（図４参照）。すなわち、わずかな平面範囲（幅範囲）内であっても、互いに隣接する製品幅の金属帯状体４９どうしの離間距離を十分確保することができる。これにより、同時に複数本の製品幅の金属帯状体４９が列間スリット装置５２から送り出された状態で間欠送りがなされ、製品幅の金属帯状体４９に揺動が生じたとしても、隣接する製品幅の金属帯状体４９が絡み合うことなく、それぞれの製品幅の金属帯状体４９を適切にカットオフ装置６０に送り出しすることができるのである。 As described above, due to the difference in the protruding amount of the receiving portion 56 with respect to the inter-row slit device 52, the metal strip 49 having the product width adjacent in the horizontal direction is horizontally (between the inter-row slit device 52 and the cut-off device 60). It can be in a state of being shifted in the (width) direction and the vertical (height) direction, respectively (see FIG. 4). That is, even within a slight plane range (width range), it is possible to secure a sufficient separation distance between the metal strips 49 having product widths adjacent to each other. As a result, even when a plurality of product-width metal strips 49 are intermittently fed while being fed from the inter-row slit device 52, even if the product-width metal strip 49 swings, the adjacent product widths Thus, the metal strips 49 having the respective product widths can be appropriately fed to the cutoff device 60 without the metal strips 49 being entangled with each other.
　カットオフ装置６０内には、搬送方向に各製品幅の金属帯状体４９を間欠的に搬送する第２送り装置６２が設けられている。第２送り装置６２の構造としては、プレス装置４７の下流側に設けられている第１送り装置５０の構造よりも、１回の送り長さが長くすることができるような構成となっている。
　第２送り装置６２は、水平方向に移動可能な搬送ユニット６４が、所定距離移動することにより製品幅の金属帯状体４９をプレス装置４７側から牽引し、カットオフ装置６０の下流側に押し出す。搬送ユニット６４の上面には、製品幅の金属帯状体４９の数だけ水平方向に並んだ複数列の送りピン６５が列状に上方に突出して配置されている。送りピン６５が各製品幅の金属帯状体４９に形成されたチューブ挿入部３４内に下方から進入し、送りピン６５が牽引することでそれぞれの製品幅の金属帯状体４９を移送位置まで移動させることができる。 In the cut-off device 60, a second feeding device 62 that intermittently conveys the metal strip 49 of each product width in the conveying direction is provided. The structure of the second feeding device 62 is configured such that one feeding length can be made longer than the structure of the first feeding device 50 provided on the downstream side of the pressing device 47. .
The second feeding device 62 pulls the metal strip 49 having a product width from the press device 47 side by pushing the transport unit 64 movable in the horizontal direction by a predetermined distance, and pushes it out to the downstream side of the cut-off device 60. On the upper surface of the transport unit 64, a plurality of rows of feed pins 65 arranged in the horizontal direction by the number of metal strips 49 having a product width are arranged to protrude upward in a row. The feed pin 65 enters the tube insertion portion 34 formed in the metal strip 49 of each product width from below, and the feed pin 65 is pulled to move the metal strip 49 of each product width to the transfer position. be able to.
　第２送り装置６２の下流側には、切断装置６６が設けられている。
　切断装置６６は、それぞれの製品幅の金属帯状体４９を所定長さに切断することにより、最終的な熱交換器用フィン３０を作成するものである。切断装置６６は、各製品幅の金属帯状体４９の上面側に配置された上刃６８と、各製品幅の金属帯状体４９の下面側に配置された下刃６９とを有する。
　上刃６８と下刃６９とが型閉じすることによって、各製品幅の金属帯状体４９が搬送方向において所定長さ寸法に切断され、熱交換器用フィン３０が製造される。 A cutting device 66 is provided on the downstream side of the second feeding device 62.
The cutting device 66 creates the final heat exchanger fins 30 by cutting the metal strips 49 of the respective product widths into predetermined lengths. The cutting device 66 has an upper blade 68 disposed on the upper surface side of the metal strip 49 of each product width and a lower blade 69 disposed on the lower surface side of the metal strip 49 of each product width.
When the upper blade 68 and the lower blade 69 are closed, the metal strip 49 of each product width is cut into a predetermined length in the conveying direction, and the heat exchanger fin 30 is manufactured.
　製造された熱交換器用フィン３０は、スタック装置８０に複数枚積層されてスタックされる。
　熱交換器用フィンのスタックの一例について説明する。カットオフ装置６０により所定寸法に切断された熱交換器用フィン３０は、保持状態を継続する保持装置７０に保持される。保持装置７０の下方には、カットオフ装置６０により所定長さに切断された熱交換器用フィン３０を積層させるためのスタック装置８０が設けられている。 A plurality of manufactured heat exchanger fins 30 are stacked and stacked on the stacking device 80.
An example of a stack of heat exchanger fins will be described. The heat exchanger fins 30 cut to a predetermined size by the cut-off device 60 are held by the holding device 70 that continues the holding state. Below the holding device 70, there is provided a stack device 80 for laminating the heat exchanger fins 30 cut to a predetermined length by the cut-off device 60.
　保持装置７０は、列間スリット装置５２から送り出される製品幅の金属帯状体４９の側方位置と製品幅の金属帯状体の保持位置との間で互いに製品幅の金属帯状体４９の搬送方向に対して直交する水平方向に接離動可能に設けられた一対の保持体（図示せず）を有している。
　スタック装置８０は、保持装置７０により保持されている熱交換器用フィン３０のチューブ挿入部３４に下方から挿通可能に立設された複数本のスタックピン８１と、スタックピン８１の下端に設けられた台座８２を有している。台座８２には台座８２を上下方向（高さ方向）に移動させるための上下動装置８３が設けられている。上下動装置８３としてはモータ駆動装置が好適に用いられる。スタック装置８０は以上に説明した構成に限定されるものではなく、他の構成例としてはマガジン状のスタック装置８０を採用することもできる。 The holding device 70 is arranged in the conveying direction of the metal strip 49 having the product width between the lateral position of the metal strip 49 having the product width and the holding position of the metal strip having the product width. A pair of holding bodies (not shown) are provided so as to be movable toward and away from each other in a horizontal direction perpendicular to the vertical direction.
The stack device 80 is provided at a lower end of the stack pin 81 and a plurality of stack pins 81 erected so as to be inserted from below into the tube insertion portion 34 of the heat exchanger fin 30 held by the holding device 70. A pedestal 82 is provided. The pedestal 82 is provided with a vertical movement device 83 for moving the pedestal 82 in the vertical direction (height direction). As the vertical movement device 83, a motor drive device is preferably used. The stack device 80 is not limited to the configuration described above, and a magazine-like stack device 80 may be adopted as another configuration example.
　また、本実施形態にかかる熱交換器用フィンの製造装置１００はＣＰＵおよび記憶部（いずれも図示せず）を有する制御部９０を有している。制御部９０の記憶部には予め熱交換器用フィンの製造装置を構成する各構成の動作制御を行うための動作制御プログラムが記憶されていて、ＣＰＵが記憶部から動作制御プログラムを読み取り、動作制御プログラムに沿って各構成の動作制御を行う。このようにＣＰＵおよび動作制御プログラムによる各構成の動作制御が行われることで、熱交換器用フィンの製造装置１００における各構成の一連の動作を連携させることが可能になっている。 Moreover, the heat exchanger fin manufacturing apparatus 100 according to the present embodiment includes a control unit 90 having a CPU and a storage unit (both not shown).

Thus, by performing operation control of each component by the CPU and the operation control program, it is possible to link a series of operations of each component in the heat exchanger fin manufacturing apparatus 100.
（第２実施形態）
　図５は第２実施形態にかかる熱交換器用フィンの製造措置の要部側面図である。図６は、図５に示す受け部５６の拡大説明図である。本実施形態においては、図５に示すように列間スリット装置５２の搬送方向における下流端位置に受け部５６を配設し、カットオフ装置６０の進入位置（搬送方向における上流端位置）に第２の受け部６１が配設されている点が特徴的である。 (Second Embodiment)
FIG. 5: is a principal part side view of the manufacturing measure of the fin for heat exchangers concerning 2nd Embodiment. FIG. 6 is an enlarged explanatory view of the receiving portion 56 shown in FIG. In the present embodiment, as shown in FIG. 5, the receiving portion 56 is disposed at the downstream end position in the transport direction of the inter-row slit device 52, and the first position is the entrance position of the cut-off device 60 (upstream end position in the transport direction). A characteristic is that two receiving portions 61 are provided.
　列間スリット装置５２側に配設された受け部５６は、図６に示すように、ベース５６Ａと、第１アーム５６Ｂと、第２アーム５６Ｃと、連結板５６Ｄと、回転体５６Ｅとを有している。第１アーム５６Ｂと第２アーム５６Ｃと連結板５６Ｄとは、軸ａを介して軸ａ周りに回動可能にされている。回転体５６Ｅは、製品幅の金属帯状体４９の下面を支持し、図６の紙面奥行き方向に延設されている。回転値５６Ｅは長手方向の両端部が第１アーム５６Ｂと第２アーム５６Ｃとによって軸ａ周りに回転可能に挟持されている。 As shown in FIG. 6, the receiving portion 56 disposed on the inter-row slit device 52 side includes a base 56A, a first arm 56B, a second arm 56C, a connecting plate 56D, and a rotating body 56E. is doing. The first arm 56B, the second arm 56C, and the connecting plate 56D are rotatable around the axis a via the axis a. The rotator 56E supports the lower surface of the metal strip 49 having a product width, and extends in the depth direction of the sheet of FIG. The rotation value 56E is sandwiched between the first arm 56B and the second arm 56C so as to be rotatable around the axis a at both ends in the longitudinal direction.
　本実施形態においては第２アーム５６Ｃまでとしているが、第３アーム以降も同様にして回動可能に連結することができる。第１アーム５６Ｂと第２アームＣと連結板５６Ｄは、それぞれに配設された円弧状の長孔ｈにピンｐを挿通させることで、長孔ｈに沿ってピンｐがガイドされた状態で軸ａ周りに回動可能に形成されている。連結板５６Ｄは、第１アーム５６Ｂと第２アーム５６Ｃとを任意の屈曲角度で固定することが可能に形成されている。 In the present embodiment, the second arm 56C is used, but the third and subsequent arms can be similarly connected so as to be rotatable. The first arm 56B, the second arm C, and the connecting plate 56D are inserted in a circular arc-shaped long hole h, and the pin p is guided along the long hole h. It is formed to be rotatable around the axis a. The connecting plate 56D is formed so that the first arm 56B and the second arm 56C can be fixed at an arbitrary bending angle.
　カットオフ装置６０の進入位置（搬送方向における上流端位置）に配設されている第２の受け部６１は、第１実施形態で用いた受け部５６と同様の構成を採用することができるので、ここでの詳細な説明は省略する。
　第２の受け部６１は、カットオフ装置６０の進入位置に対する取り付け角度が調整可能であるため、製品幅の金属帯状体４９のカットオフ装置６０への取り込み角度（製品幅の金属帯状体４８の下方へのたるみ状態からの復元位置）を適宜調整することができる。図５に示すようにカットオフ装置６０への製品幅の金属帯状体４９の取り込み角度を変更することでも、列方向に隣接する製品幅の金属帯状体４９どうしを離反させることができ、製品幅の金属帯状体４９の下方へのたるみ部分における列方向に隣接する製品幅の金属帯状体４９どうしの絡みをより確実に防止することができる。 Since the 2nd receiving part 61 arrange | positioned in the approach position (upstream end position in a conveyance direction) of the cutoff apparatus 60 can employ | adopt the structure similar to the receiving part 56 used in 1st Embodiment. Detailed description will be omitted here.
Since the mounting angle of the second receiving portion 61 with respect to the entry position of the cut-off device 60 can be adjusted, the take-in angle of the product-width metal strip 49 into the cut-off device 60 (the width of the metal strip 48 of the product width) It is possible to appropriately adjust the restoration position from the downward slack state. As shown in FIG. 5, the product width metal strips 49 adjacent to each other in the column direction can be separated from each other by changing the angle at which the product width metal strips 49 are taken into the cutoff device 60 as well. The tangling of the metal strips 49 having the product width adjacent to each other in the column direction in the slack portion below the metal strips 49 can be more reliably prevented.
　列間スリット装置５２からの受け部５６の張り出し長さを異ならせることにより、列間スリット装置５２側における製品幅の金属帯状体４９のたるみ形状（ループ形状）におけるたるみ開始位置は、図５に示すように製品幅の金属帯状体４９の搬送方向においてΔＬ０相違させることができる。また、カットオフ装置６０からの第２の受け部６１の張り出し長さを異ならせることにより、カットオフ装置６０への進入開始位置（製品幅の金属帯状体４９の下方へのたるみ状態からの復元位置）を製品幅の金属帯状体４９の搬送方向においてΔＬ１相違させることができる。 FIG. 5 shows the sag start position in the slack shape (loop shape) of the metal strip 49 of the product width on the side of the inter-slit device 52 by varying the protruding length of the receiving portion 56 from the inter-row slit device 52. As shown, ΔL0 can be made different in the conveying direction of the metal strip 49 having the product width. Further, by changing the overhanging length of the second receiving portion 61 from the cut-off device 60, the entry start position into the cut-off device 60 (recovery from the state in which the product width of the metal strip 49 is slacked downward) Position) can be made to differ by ΔL1 in the conveying direction of the metal strip 49 having the product width.
　第１実施形態と同様に、列間スリット装置５２から送り出される製品幅の金属帯状体４９は受け部５６および第２受け部６１の装着の有無にかかわらず同じ長さである。したがって、製品幅の金属帯状体４９の下方へのたるみ開始位置およびたるみ状態からの復元位置を異ならせることにより、たるみの頂点高さ位置も異ならせることができる。図５に示すように、製品幅の金属帯状体４９をたるませた部分の下端部（ループ下端位置）においては頂点高さ位置をΔｈ０相違させることができ、製品幅の金属帯状体４９をたるませた部分の上端部（ループ上端位置）においては、頂点高さ位置をΔｈ１相違させることができる。 As in the first embodiment, the metal strip 49 having the product width sent out from the inter-row slit device 52 has the same length regardless of whether or not the receiving portion 56 and the second receiving portion 61 are mounted. Therefore, the sag apex height position can be made different by changing the sag start position of the metal strip 49 having the product width downward and the restoration position from the sag state. As shown in FIG. 5, the apex height position can be made different by Δh0 at the lower end portion (loop lower end position) of the portion where the metal band 49 having the product width is slackened, and the metal band 49 having the product width is slapped. At the upper end portion (loop upper end position) of the bent portion, the apex height position can be made different by Δh1.
　このように、列間スリット装置５２とカットオフ装置６０との間で、製品幅の金属帯状体４９を下方にたるませている部分においては、その全範囲において、製品幅の金属帯状体４９の搬送方向の前後方向と高さ方向のそれぞれにおいて、隣接する製品幅の金属帯状体４９を確実に離反させることができる。これにより、隣接する製品幅の金属帯状体４９が間欠送りされて揺動を生じたとしても、製品幅の金属帯状体４９どうしの絡み合いをより確実に防止することができる点で好都合である。 In this way, in the portion where the metal strip 49 having the product width is slackened downward between the inter-row slit device 52 and the cut-off device 60, the metal strip 49 having the product width is in the entire range. In each of the front-rear direction and the height direction in the transport direction, the adjacent metal strips 49 having the product width can be reliably separated. This is advantageous in that even if the adjacent metal strips 49 having the product width are intermittently fed and oscillated, the entanglement between the metal strips 49 having the product width can be more reliably prevented.
　以上本発明につき好適な実施形態を挙げて種々説明したが、本発明はこの実施形態に限定されるものではなく、発明の精神を逸脱しない範囲内で多くの改変を施し得るのはもちろんである。例えば、第１実施形態においては、列間スリット装置５２に受け部５６を取り付けした実施形態について、第２実施体においては列間スリット装置５２に受け部５６を、カットオフ装置６０に第２の受け部６１をそれぞれ配設した実施形態について説明したがこれらの実施形態に限定されるものではない。 While the present invention has been described above with reference to a preferred embodiment, the present invention is not limited to this embodiment, and it goes without saying that many modifications can be made without departing from the spirit of the invention. . For example, in the first embodiment, with respect to the embodiment in which the receiving portion 56 is attached to the inter-row slit device 52, in the second embodiment, the receiving portion 56 is connected to the inter-row slit device 52 and the cut-off device 60 is connected to the second. Although the embodiments in which the receiving portions 61 are disposed have been described, the present invention is not limited to these embodiments.
　具体的にはカットオフ装置６０における製品幅の金属帯状体４９の搬送方向の上流側端部（進入位置）のみ受け部を取り付けした形態を採用することもできる。また、第２実施形態における列間スリット装置５２とカットオフ装置６０とにそれぞれ配設した受け部５６および第２の受け部６１とを入れ替えて配設した形態を採用してもよい。 Specifically, it is possible to adopt a form in which the receiving portion is attached only to the upstream end portion (entrance position) in the transport direction of the metal strip 49 having the product width in the cutoff device 60. Moreover, you may employ | adopt the form which replaced and arrange | positioned the receiving part 56 and the 2nd receiving part 61 which were each arrange | positioned at the slit apparatus 52 and the cut-off apparatus 60 in 2nd Embodiment.
　また、本実施形態においては、受け部５６を列間スリット装置５２における製品幅の金属帯状体４９の搬送方向における下流端位置からカットオフ装置６０に向って延設した形態について説明しているが、この形態に限定されるものではない。
　具体的には、受け部５６を列間スリット装置５２における製品幅の金属帯状体４９の搬送方向における下流端位置からカットオフ装置６０に向って徐々に高さ位置を増やす方向に延設することもできる。この形態によれば、受け部５６が配設されていない第１列目と第３列目の製品幅の金属帯状体４９に対する第２列目と第４列目の製品幅の金属帯状体４９の離間距離をさらに増加させることができる点で好都合である。 In the present embodiment, the receiving portion 56 is described as extending from the downstream end position in the conveying direction of the metal strip 49 having the product width in the inter-row slit device 52 toward the cutoff device 60. However, it is not limited to this form.
Specifically, the receiving portion 56 is extended from the downstream end position in the conveyance direction of the metal strip 49 having the product width in the inter-row slit device 52 in a direction in which the height position is gradually increased toward the cutoff device 60. You can also. According to this embodiment, the metal strip 49 having the product width in the second row and the fourth row with respect to the metal strip 49 having the product width in the first row and the third row in which the receiving portion 56 is not provided. This is advantageous in that the separation distance can be further increased.
　また、受け部５６は、図７に示すように、列間スリット装置５２とカットオフ装置６０との間の位置において独立した構成にすることもできる。このとき受け部５６は、図７に示すように、台座５６ｘと台座５６ｘから起立する支柱５６ｙと支柱５６ｙに沿って高さ位置が調整可能な材料受体５６ｗが取り付けられた移動体５６ｚとを有していることが好ましい。支柱５６ｙの高さ方向における移動体５６ｚの固定位置を調整することで、製品幅の金属帯状体４９の下方へのたるみ状態を適宜変更することができるからである。 Further, as shown in FIG. 7, the receiving portion 56 may be configured to be independent at a position between the inter-row slit device 52 and the cut-off device 60. At this time, as shown in FIG. 7, the receiving portion 56 includes a pedestal 56x, a support 56y that stands up from the pedestal 56x, and a moving body 56z to which a material receiver 56w whose height position can be adjusted along the support 56y is attached. It is preferable to have. This is because by adjusting the fixed position of the movable body 56z in the height direction of the support column 56y, the state of the product width of the metal strip 49 can be appropriately changed.
　また、材料受体５６ｗは、図７内の矢印Ｚ方向に回動可能にしてもよい。さらには、移動体５６ｚを支柱５６ｙに対して取り付け位置を固定した構成を採用してもよい。このような形態の場合においては、受け部５６全体の配設位置を適宜調整すればよい。
　要は、列間スリット装置５２から送り出された製品幅の金属帯状体４９が列間スリット装置５２とカットオフ装置６０との間で、下方にたるんだ状態を経た後にカットオフ装置６０に進入する際において、互いに隣接する製品幅の金属帯状体４９どうしのたるみ形状を異ならせることができればよいのである。 Further, the material receiver 56w may be rotatable in the arrow Z direction in FIG. Furthermore, you may employ | adopt the structure which fixed the attachment position with respect to the support | pillar 56y with respect to the mobile body 56z. In the case of such a form, the arrangement position of the entire receiving portion 56 may be adjusted as appropriate.
The point is that the metal strip 49 having the product width sent from the inter-row slit device 52 sags downward between the inter-row slit device 52 and the cut-off device 60 and then enters the cut-off device 60. In this case, it is only necessary that the slack shapes of the metal strips 49 having product widths adjacent to each other can be made different.
　したがって、図７に示す受け部５６を採用する場合には、列間スリット装置５２から送り出される製品幅の金属帯状体４９の全てに対して配設する必要はなく、列間スリット装置５２から送り出される製品幅の金属帯状体４９に対して一列おきに配設することも可能である。 Therefore, when the receiving portion 56 shown in FIG. 7 is adopted, it is not necessary to dispose all the metal strips 49 of the product width sent out from the inter-row slit device 52, but sent out from the inter-row slit device 52. It is also possible to arrange every other row with respect to the metal strip 49 having a product width.
　また、製品幅の金属帯状体４９を列間スリット装置５２から直ちに宙吊り状態にしても自重により折れてしまうことがないことが担保されていれば、実施形態１と実施形態２とにおいて説明した受け部５６についても、列間スリット装置５２から送り出される製品幅の金属帯状体４９に対して一列おきに配設する形態を採用することも可能である。 Further, if it is ensured that the metal strip 49 having the product width is suspended from the inter-row slit device 52 immediately in the suspended state, it is guaranteed that the metal strip 49 will not be broken by its own weight, as described in the first and second embodiments. It is also possible to adopt a form in which the portions 56 are arranged in every other row with respect to the metal strip 49 having the product width sent out from the inter-row slit device 52.
　また、本発明にかかる熱交換器用フィンの製造装置１００で製造する熱交換器用フィン３０の形態は、図２に示す金属帯状体４８を個片化して得られるいわゆる扁平チューブ用放熱フィンの形態に限定されるものではなく、長手方向（搬送方向）の中心線に対称な形態を有するいわゆる丸管タイプの熱交換器用フィン３０を製造することもできる。
　さらには、以上に説明したすべての構成を適宜組み合わせた熱交換器用フィンの製造装置１００を採用することもできる。 Further, the heat exchanger fin 30 manufactured by the heat exchanger fin manufacturing apparatus 100 according to the present invention is in the form of a so-called flat tube heat radiating fin obtained by dividing the metal strip 48 shown in FIG. It is not limited, The fin 30 for heat exchangers of what is called a round tube type which has a form symmetrical to the centerline of a longitudinal direction (conveyance direction) can also be manufactured.
Furthermore, a heat exchanger fin manufacturing apparatus 100 in which all the configurations described above are appropriately combined may be employed.
