Description
本発明は、熱交換用フィン等の被搬送物を間欠的に搬送する間欠搬送装置に関する。 The present invention relates to an intermittent conveyance device that intermittently conveys an object to be conveyed such as a heat exchange fin.
エアコンディショナ等に装着される熱交換用フィンは、薄板金属材料からなる帯状体に加工が施されて製造される。帯状体は、穴開け加工が施されて長手方向に間隔をおいて多数の開口が形成され、次いでバーリング加工が施されて各開口周縁部から突出する円筒状カラーが形成され、次いでリフレア加工が施されて円筒状カラーの先端側が基端側に向かって折り返され、次いで切断加工が施されて長手方向に奇数個の開口又は偶数個の開口を有する適宜の長さに切断される。 A heat exchange fin to be mounted on an air conditioner or the like is manufactured by processing a band-shaped body made of a thin metal material. The band-shaped body is drilled to form a large number of openings at intervals in the longitudinal direction, and then subjected to burring to form a cylindrical collar protruding from the peripheral edge of each opening, and then the flaring process is performed. Then, the distal end side of the cylindrical collar is folded back toward the proximal end side, and then a cutting process is performed to cut into an appropriate length having an odd number of openings or an even number of openings in the longitudinal direction.
通常、穴開け加工、バーリング加工及びリフレア加工は、プレス機の金型装置によって施され、切断加工はプレス機の切断装置によって施される。金型装置によって加工が施された帯状体は、金型装置と同期して駆動する間欠搬送装置によって、間欠的に所定搬送ピッチで金型装置から切断装置へ搬送される。間欠搬送装置では、搬送効率の向上を図るため、１回の搬送ピッチが２ピッチ（長手方向において隣接する開口の中心間距離の２倍の距離）に設定されることがある。この場合に、長手方向に偶数個の開口を有する熱交換用フィンを製造するときは搬送ピッチが２ピッチのままでよいが、長手方向に奇数個の開口を有する熱交換用フィンを製造するときは搬送ピッチを２ピッチから１ピッチに適宜変更する必要がある。たとえば、長手方向において１１個の開口を有する長さの熱交換用フィンを製造するときには、金型装置から切断装置へと帯状体を２ピッチで５回搬送し、１ピッチで１回搬送する必要がある。 Usually, drilling, burring, and reflaring are performed by a die device of a press machine, and cutting is performed by a cutting device of the press machine. The belt-like body processed by the mold apparatus is intermittently conveyed from the mold apparatus to the cutting apparatus at a predetermined conveyance pitch by an intermittent conveyance apparatus that is driven in synchronization with the mold apparatus. In the intermittent conveyance device, in order to improve the conveyance efficiency, one conveyance pitch may be set to 2 pitches (a distance twice the distance between the centers of adjacent openings in the longitudinal direction). In this case, when manufacturing a heat exchange fin having an even number of openings in the longitudinal direction, the conveying pitch may be 2 pitches, but when manufacturing a heat exchange fin having an odd number of openings in the longitudinal direction. Needs to appropriately change the transport pitch from 2 pitches to 1 pitch. For example, when manufacturing a heat exchanging fin having a length of 11 openings in the longitudinal direction, it is necessary to convey the belt-like body five times at two pitches from the mold device to the cutting device, and once at one pitch. There is.
下記特許文献１には、搬送ピッチを変更可能な間欠搬送装置の駆動機構が開示されている。この駆動機構は、モータにより回転される円板と、円板の偏心位置に旋回自在に連結された連結棒と、基端部が連結棒の先端に旋回自在に連結されたリンクと、基端部がリンクの先端に連結されたレバーと、レバーの揺動角度を調整するシリンダ装置とを含む。レバーは、その中間部を中心として揺動自在に構成されている。レバーの先端には、往復動自在に装着された搬送手段が連結されている。そして、この間欠搬送装置では、モータの回転により連結棒及びリンクを介してレバーが所定角度で揺動し、レバーの揺動により搬送手段が往復動することによって、熱交換用フィンが間欠的に所定搬送ピッチで搬送される。また、この間欠搬送装置の駆動機構では、シリンダ装置によってレバーの揺動角度が変更されると、これに応じて搬送手段の搬送ピッチが変更される。 Patent Document 1 below discloses a drive mechanism for an intermittent conveyance device that can change the conveyance pitch. The drive mechanism includes a disc rotated by a motor, a connecting rod pivotally connected to an eccentric position of the disc, a link having a base end pivotally connected to a tip of the connecting rod, and a base end The lever includes a lever connected to the tip of the link, and a cylinder device that adjusts the swing angle of the lever. The lever is configured to be swingable about its middle part. Conveying means mounted so as to be capable of reciprocating is connected to the tip of the lever. In this intermittent conveyance device, the lever is swung at a predetermined angle through the connecting rod and the link by the rotation of the motor, and the conveying means is reciprocated by the rocking of the lever, whereby the heat exchange fin is intermittently moved. It is transported at a predetermined transport pitch. Further, in the drive mechanism of the intermittent transport device, when the swing angle of the lever is changed by the cylinder device, the transport pitch of the transport means is changed accordingly.
プレス機には、金型装置において毎分５００回程度の高速加工が行われるものがある。しかし、上記特許文献１に開示された間欠搬送装置の駆動機構のように、レバーの揺動角度の変更（すなわち、搬送手段の搬送ピッチの変更）がシリンダ装置で行われる場合には、金型装置に同期して駆動する間欠搬送装置の搬送速度を落とさなければ、レバーの揺動角度の変更が間欠搬送装置の搬送速度に追従することができない。このため、搬送速度を落とさずに、搬送ピッチを変更することが困難である。 Some press machines perform high-speed machining about 500 times per minute in a mold apparatus. However, when the change of the lever swing angle (that is, the change of the transfer pitch of the transfer means) is performed by the cylinder device as in the driving mechanism of the intermittent transfer apparatus disclosed in Patent Document 1, the mold is used. Unless the conveyance speed of the intermittent conveyance device driven in synchronism with the apparatus is reduced, the change of the swing angle of the lever cannot follow the conveyance speed of the intermittent conveyance device. For this reason, it is difficult to change the transport pitch without reducing the transport speed.
上記事実に鑑みてなされた本発明の課題は、搬送速度を落とさずに搬送ピッチを変更することができる間欠搬送装置を提供することである。 The subject of this invention made | formed in view of the said fact is providing the intermittent conveyance apparatus which can change a conveyance pitch, without reducing conveyance speed.

The movable body 16 having a prismatic shape as a whole extending in the Y direction has both ends in the Y direction formed in a columnar shape. Four guided blocks 18 are fixed to the lower surface of the movable body 16 at intervals in the Y direction. The movable body 16 is mounted on the base 4 so as to reciprocate in the X direction along the guide rail 14 by engaging the guided block 18 and the guide rail 14 of the base 4.
図２及び図３を参照して説明する。図２に示すとおり、第１搬送手段６の可動体１６には、Ｙ方向に間隔をおいて３個の円筒状の中空部２０が形成されている。各中空部２０には位置付け手段２２が配置されている。図３に示すとおり、位置付け手段２２は、上下方向に移動自在に中空部２０に配置された円板状のピストン２４と、ピストン２４の上面に固定された基端部から上方に延びる円柱状のロッド２６とを含む。各中空部２０の天面壁２８には、ロッド２６の直径に対応する直径の円形状開口２８ａが形成されている。ロッド２６の先端部は、開口２８ａを通って天面壁２８から突出している。天面壁２８の下面とピストン２４の上面との間には、中空部２０の下端側の初期位置にピストン２４を付勢するスプリング３０が配置されている。各中空部２０の底面壁３２にも開口３２ａが形成されていて、開口３２ａを通って圧空源（図示していない。）から選択的に中空部２０の下端部に圧空が供給される。 This will be described with reference to FIGS. As shown in FIG. 2, three cylindrical hollow portions 20 are formed in the movable body 16 of the first transport unit 6 at intervals in the Y direction. Positioning means 22 is disposed in each hollow portion 20. As shown in FIG. 3, the positioning means 22 includes a disk-shaped piston 24 disposed in the hollow portion 20 so as to be movable in the vertical direction, and a columnar shape extending upward from a base end portion fixed to the upper surface of the piston 24. Rod 26. A circular opening 28 a having a diameter corresponding to the diameter of the rod 26 is formed in the top wall 28 of each hollow portion 20.

That is, when the piston 24 is positioned at the initial position by the urging force of the spring 30, the engaging member 34 is positioned at the non-operating position. When the compressed air is supplied from the compressed air source to the lower end portion of the hollow portion 20, the piston 24 rises against the urging force of the spring 30, so that the engaging member 34 is raised from the non-operating position to the operating position. The Further, when the compressed air is discharged from the hollow portion 20, the piston 24 is lowered by the urging force of the spring 30, so that the engaging member 34 is lowered from the operating position to the non-operating position.

図９を参照して説明する。間欠搬送装置２によって帯状体９６が搬送される際は、電動モータ（図示していない。）の回転運動がカム（図示していない。）によって揺動運動に変換されてシャフト６４に伝達される。これによってシャフト６４と共にレバー６６が揺動される。レバー６６が揺動されると、第１リンク６８を介して第１搬送手段６が第１搬送ピッチＰ１でＸ方向に往復動すると共に、第２リンク７０を介して第２搬送手段８が第１搬送ピッチＰ１とは異なる第２搬送ピッチＰ２でＸ方向に往復動する。図示の実施形態では、第１搬送ピッチＰ１は、長手方向において隣接する開口９８の中心間距離Ｌ（図８参照。）と同じ距離に設定されている（Ｐ１＝Ｌ）。第２搬送ピッチＰ２は、上記中心間距離Ｌの２倍の距離に設定されている（Ｐ２＝２Ｌ）。すなわち、第１搬送ピッチＰ１は第２搬送ピッチＰ２よりも短い（Ｐ１＜Ｐ２）。なお図９では、レバー６６の揺動範囲における片側端部にレバー６６が位置する場合の、レバー６６、第１リンク６８、第２リンク７０、第１搬送手段６及び第２搬送手段８を実線で示すと共に、レバー６６の揺動範囲における他側端部にレバー６６が位置する場合の、レバー６６、第１リンク６８、第２リンク７０、第１搬送手段６及び第２搬送手段８を二点鎖線で示している。 This will be described with reference to FIG. When the strip 96 is transported by the intermittent transport device 2, the rotational motion of an electric motor (not shown) is converted into a swing motion by a cam (not shown) and transmitted to the shaft 64. . As a result, the lever 66 is swung together with the shaft 64. When the lever 66 is swung, the first transport unit 6 reciprocates in the X direction at the first transport pitch P 1 via the first link 68, and the second transport unit 8 moves via the second link 70. It reciprocates in the X direction at a second transport pitch P 2 different from the first transport pitch P 1 . In the illustrated embodiment, the first transport pitch P 1 is set to the same distance as the center distance L (see FIG. 8) between the openings 98 adjacent in the longitudinal direction (P 1 = L). Second conveying pitch P 2 is set to twice the distance of the center distance L (P 2 = 2L). That is, the first conveying pitch P 1 is shorter than the second conveying pitch P 2 (P 1 <P 2 ). In FIG. 9, the lever 66, the first link 68, the second link 70, the first conveying means 6 and the second conveying means 8 when the lever 66 is located at one end in the swinging range of the lever 66 are shown by solid lines. And the lever 66, the first link 68, the second link 70, the first conveying means 6 and the second conveying means 8 when the lever 66 is positioned at the other end in the swinging range of the lever 66. It is indicated by a dotted line.
第１搬送手段６及び第２搬送手段８が往動される際に、第１搬送手段６の係合部材３４が位置付け手段２２によって作用位置（上昇位置）に位置付けられる（上昇される）と、帯状体９６の開口９８に係合ピン３８が嵌入することによって帯状体９６に係合部材３４が係合し、第１搬送手段６によって第１搬送ピッチＰ１だけ帯状体９６が搬送路１０２（図１参照。）の上面に沿って搬送される。また、第１搬送手段６及び第２搬送手段８が復動される際には、第１搬送手段６の係合部材３４が位置付け手段２２によって非作用位置（下降位置）に位置付けられる（下降される）ことによって、帯状体９６から係合部材３４が離隔する。このように、第１搬送手段６の往復動及び係合部材３４の昇降動との組合せにより、帯状体９６は第１搬送ピッチＰ１で搬送路１０２の上面に沿ってＸ方向に間欠的に搬送される。 When the first conveying means 6 and the second conveying means 8 are moved forward, the engaging member 34 of the first conveying means 6 is positioned (raised) by the positioning means 22 at the operating position (raised position). the engaging member 34 engages the strip 96 by the engaging pin 38 into the opening 98 of the strip 96 is fitted, by the first conveying unit 6 by the first conveying pitch P 1 is strip 96 transport path 102 ( It is conveyed along the upper surface of FIG. Further, when the first transport unit 6 and the second transport unit 8 are moved backward, the engaging member 34 of the first transport unit 6 is positioned (lowered) by the positioning unit 22 at the non-operating position (lowering position). As a result, the engaging member 34 is separated from the belt-like body 96. Thus, by the combination of the lifting and lowering of the reciprocating and engaging member 34 of the first conveying unit 6, the strip 96 is intermittently in the X direction along the top surface of the conveying path 102 by the first conveying pitch P 1 Be transported.
他方、第１搬送手段６及び第２搬送手段８が往動される際に、第２搬送手段８の係合部材５８が位置付け手段４６によって作用位置（上昇位置）に位置付けられる（上昇される）と、帯状体９６の開口９８に係合ピン６２が嵌入することによって帯状体９６に係合部材５８が係合し、第２搬送手段８によって第２搬送ピッチＰ２だけ帯状体９６が搬送路１０２の上面に沿って搬送される。また、第１搬送手段６及び第２搬送手段８が復動される際には、第２搬送手段８の係合部材５８が位置付け手段４６によって非作用位置（下降位置）に位置付けられる（下降される）ことによって、帯状体９６から係合部材５８が離隔する。このように、第２搬送手段８の往復動及び係合部材５８の昇降動との組合せにより、帯状体９６は第２搬送ピッチＰ２で搬送路１０２の上面に沿ってＸ方向に間欠的に搬送される。 On the other hand, when the first conveying means 6 and the second conveying means 8 are moved forward, the engaging member 58 of the second conveying means 8 is positioned (raised) by the positioning means 46 at the operating position (raised position). When the engaging member 58 engages the strip 96 by the engaging pin 62 is fitted into the opening 98 of the strip 96, the second conveyance pitch P 2 only strip 96 is conveying path by the second conveying means 8 It is conveyed along the upper surface of 102. Further, when the first conveying means 6 and the second conveying means 8 are moved backward, the engaging member 58 of the second conveying means 8 is positioned (lowered) by the positioning means 46 at the non-operating position (lowering position). As a result, the engaging member 58 is separated from the belt-like body 96. Thus, by the combination of the lifting and lowering of the reciprocating and engaging member 58 of the second conveying means 8, strip 96 is intermittently in the X direction along the top surface of the conveying path 102 by the second conveying pitch P 2 Be transported.
長手方向に偶数個の開口９８を有する熱交換用フィンを製造する場合には、金型装置から切断装置（図示していない。）へと第２搬送手段８によって第２搬送ピッチＰ２で帯状体９６を搬送することにより、搬送効率の向上が図られる。また、長手方向に奇数個の、たとえば１１個の開口９８を有する熱交換用フィンを製造する場合には、金型装置から切断装置へと第２搬送手段８によって第２搬送ピッチＰ２で帯状体９６を５回搬送し、第１搬送手段６によって第１搬送ピッチＰ１で帯状体９６を１回搬送することにより、搬送効率の低下を抑制しつつ、長手方向に１１個の開口９８を有する熱交換用フィンを製造することができる。 When manufacturing a fin for a heat exchanger having an even number of openings 98 in the longitudinal direction, the cutting device from the mold device (not shown.) To a strip with the second conveying pitch P 2 by the second conveying means 8 By conveying the body 96, the conveyance efficiency is improved. Also, the odd number in the longitudinal direction, for example, 11 pieces of the case of manufacturing a fin for a heat exchanger having an opening 98 is strip-shaped in the second conveying pitch P 2 to the cutting device from the mold apparatus by the second conveying means 8 The body 96 is transported 5 times, and the belt-like body 96 is transported once at the first transport pitch P 1 by the first transport means 6, so that 11 openings 98 are formed in the longitudinal direction while suppressing a decrease in transport efficiency. The fin for heat exchange which has can be manufactured.
拘束手段１２は、第１搬送手段６及び第２搬送手段８が往動される際には、拘束部材９０が作動手段７６によって非拘束位置（下降位置）に位置付けられ、帯状体９６の移動を許容する。一方、拘束手段１２は、第１搬送手段６及び第２搬送手段８が復動される際には、拘束部材９０が作動手段７６によって拘束位置（上昇位置）に位置付けられ、帯状体９６の開口９８に拘束ピン９４が嵌入することによって帯状体９６に拘束部材９０が係合し、帯状体９６の移動（位置ズレ等）を阻止する。 When the first conveying means 6 and the second conveying means 8 are moved forward, the restraining means 12 is positioned by the actuating means 76 at the non-restraining position (lowering position), and the restraining member 90 moves the belt-like body 96. Allow. On the other hand, when the first conveying means 6 and the second conveying means 8 are moved backward, the restricting means 12 is positioned at the restricting position (upward position) by the actuating means 76 and the opening of the belt-like body 96 is determined. When the restraining pin 94 is inserted into 98, the restraining member 90 is engaged with the belt-like body 96, and the movement (positional deviation or the like) of the belt-like body 96 is prevented.
上述のとおり、間欠搬送装置２は、第１搬送手段６及び第２搬送手段８が往動される際に、第１搬送手段６の係合部材３４が作用位置に位置付けられると第１搬送手段６によって帯状体９６が第１搬送ピッチＰ１だけ搬送され、第２搬送手段８の係合部材５８が作用位置に位置付けられると第２搬送手段８によって帯状体９６が第２搬送ピッチＰ２だけ搬送されるので、第１搬送手段６の係合部材３４と第２搬送手段８の係合部材５８とを選択的に非作用位置から作用位置へと位置付けることによって搬送速度を落とさずに搬送ピッチを変更することができる。 As described above, when the first conveying means 6 and the second conveying means 8 are moved forward, the intermittent conveying apparatus 2 is configured such that when the engaging member 34 of the first conveying means 6 is positioned at the operating position, the first conveying means. 6, the belt 96 is transported by the first transport pitch P 1, and when the engaging member 58 of the second transport means 8 is positioned at the operating position, the belt 96 is transported by the second transport means 8 by the second transport pitch P 2. Since it is transported, it is possible to selectively position the engaging member 34 of the first transporting means 6 and the engaging member 58 of the second transporting means 8 from the non-operating position to the operating position without reducing the transport speed. Can be changed.
また、第１搬送手段６及び第２搬送手段が復動される際は、第１搬送手段６の係合部材３４及び第２搬送手段８の係合部材５８が帯状体９６から離隔するので、第１搬送手段６の係合ピン３８の先端及び第２搬送手段８の係合ピン６２先端が帯状体９６の下面に接触することがない。したがって、第１搬送手段６及び第２搬送手段が復動される際に、係合ピン３８及び６２が帯状体９６の下面に摺接することによって、帯状体９６の下面に傷が発生することや帯状体９６が変形することが防止される。 Further, when the first conveying means 6 and the second conveying means are moved backward, the engaging member 34 of the first conveying means 6 and the engaging member 58 of the second conveying means 8 are separated from the belt-like body 96. The front end of the engagement pin 38 of the first transport unit 6 and the front end of the engagement pin 62 of the second transport unit 8 do not contact the lower surface of the strip 96. Therefore, when the first conveying means 6 and the second conveying means are moved backward, the engaging pins 38 and 62 are brought into sliding contact with the lower surface of the belt-like body 96, so that the lower surface of the belt-like body 96 is damaged. The strip 96 is prevented from being deformed.
