　しかしながら、特許文献１に開示された発明には、引締対象となるバンドがある程度は限られるという問題点がある。 However, the invention disclosed in Patent Document 1 has a problem in that the bands that can be tightened are limited to some extent.
　本発明の目的は、引締対象となるバンドの範囲を拡大することにある。 An object of the present invention is to expand the range of bands to be tightened.
　図面が参照されつつ本発明は説明される。なおこの欄で図中の符号を使用したのは発明の内容の理解を助けるためである。この欄で図中の符号を使用することには発明の内容を図示した範囲に限定する意図がない。 The invention will be described with reference to the drawings. Note that the reference numerals in the figures are used in this column to aid understanding of the content of the invention. The use of reference numerals in the figures in this column is not intended to limit the scope of the invention to the scope shown.
　上述された目的を達成するために、本発明のある局面に従うと、バンド引締装置１０は、スライド面７２を有するハウジング部２０と、グリッピング機構２２と、往復機構２４とを備える。グリッピング機構２２は、スライド面７２に沿った往復に伴ってバンド５００を引っ張る。往復機構２４は、スライド面７２に沿ってグリッピング機構２２を往復させる。そのグリッピング機構２２が、チャックベース９０と、押付グリッパ９２とを有している。チャックベース９０は、スライド面７２へスライド可能に接する。押付グリッパ９２は、バンド５００をチャックベース９０へ押し付ける。そのチャックベース９０が、形成壁１１０，１１０の対と、バンド支持部１１２とを有している。形成壁１１０，１１０の対は、接触面１３０をそれぞれ有する。接触面１３０は、スライド面７２へ接触する。形成壁１１０，１１０の対は、バンド５００の進入路１２２を形成する。バンド支持部１１２は、形成壁１１０，１１０の対にまたがるように形成壁１１０，１１０の対に連なる。バンド支持部１１２が、傾斜対向面１７０を有している。その傾斜対向面１７０は、進入路１２２に対向している。その傾斜対向面１７０は、バンド５００の進入口１２０に近づくにつれ接触面１３０へ近づくよう接触面１３０に対して傾斜している。押付グリッパ９２は、チャックベース９０のうち傾斜対向面１７０へバンド５００をスライド可能に押し付ける。 In order to achieve the above-mentioned object, according to one aspect of the present invention, the band tightening device 10 includes a housing part 20 having a sliding surface 72, a gripping mechanism 22, and a reciprocating mechanism 24. The gripping mechanism 22 pulls the band 500 as it reciprocates along the slide surface 72. The reciprocating mechanism 24 reciprocates the gripping mechanism 22 along the slide surface 72. The gripping mechanism 22 includes a chuck base 90 and a pressing gripper 92. The chuck base 90 is slidably in contact with the slide surface 72. The pressing gripper 92 presses the band 500 against the chuck base 90. The chuck base 90 has a pair of forming walls 110, 110 and a band support portion 112. The pair of forming walls 110, 110 each have a contact surface 130. Contact surface 130 contacts slide surface 72 . The pair of forming walls 110, 110 form an entry path 122 for the band 500. The band support portion 112 continues to the pair of forming walls 110, 110 so as to span the pair of forming walls 110, 110. Band support portion 112 has an inclined opposing surface 170. The inclined opposing surface 170 faces the approach path 122 . The inclined opposing surface 170 is inclined with respect to the contact surface 130 so as to approach the contact surface 130 as it approaches the entrance 120 of the band 500. The pressing gripper 92 slidably presses the band 500 against the inclined opposing surface 170 of the chuck base 90.
　グリッピング機構２２は、スライド面７２に沿った往復に伴ってバンド５００を引っ張る。往復機構２４は、スライド面７２に沿ってグリッピング機構２２を往復させる。グリッピング機構２２が、チャックベース９０を有している。チャックベース９０が、バンド支持部１１２を有している。バンド支持部１１２が、傾斜対向面１７０を有している。押付グリッパ９２は、チャックベース９０のうち傾斜対向面１７０へバンド５００をスライド可能に押し付ける。進入路１２２に進入したバンド５００を引っ張る方向へチャックベース９０がスライドすると、バンド５００は傾斜対向面１７０に接触して引っ張られることとなる。そのバンド５００の引っ張りが可能であることにより、引っ張りの対象となるバンド５００に関する制約が減少する。その結果、本発明にかかるバンド引締装置１０は、引締対象となるバンドの範囲を拡大できる。 The gripping mechanism 22 pulls the band 500 as it reciprocates along the slide surface 72. The reciprocating mechanism 24 reciprocates the gripping mechanism 22 along the slide surface 72. The gripping mechanism 22 has a chuck base 90. The chuck base 90 has a band support portion 112. Band support portion 112 has an inclined opposing surface 170. The pressing gripper 92 slidably presses the band 500 against the inclined opposing surface 170 of the chuck base 90. When the chuck base 90 slides in the direction of pulling the band 500 that has entered the entrance path 122, the band 500 comes into contact with the inclined opposing surface 170 and is pulled. By being able to stretch the band 500, constraints on the band 500 that is subject to tension are reduced. As a result, the band tightening device 10 according to the present invention can expand the range of bands to be tightened.
　また、上述されたグリッピング機構２２が、支持体９８をさらに有していることが望ましい。支持体９８は、バンド５００の進入口１２０においてバンド５００を支持する。 Furthermore, it is desirable that the gripping mechanism 22 described above further includes a support body 98. Support 98 supports band 500 at entrance 120 of band 500.
　バンド５００を引っ張ったチャックベース９０が元の位置へ戻るように往復機構２４によってスライドさせられるとき、引っ張られたバンド５００にかかっていた張力は減少する。次に述べられる場合、バンド５００のうち進入路１２２の内部に進入した部分はその進入路１２２の内部で屈曲しやすくなる。その場合とは、そのバンド５００のうちバンド５００の進入口１２０に入っていない部分の、その張力の減少に伴う動きが乏しい場合である。支持体９８は、バンド５００の進入口１２０においてバンド５００を支持する。バンド５００が支持体９８に支持されるので、バンド５００のうち屈曲しやすくなった部分が屈曲しようとしても、その屈曲は抑制される。その結果、進入路１２２の内部でのバンド５００の屈曲は抑制される。 When the chuck base 90 that has pulled the band 500 is slid by the reciprocating mechanism 24 to return to its original position, the tension applied to the pulled band 500 is reduced. In the following case, the portion of the band 500 that has entered the entrance path 122 is likely to bend inside the entrance path 122. In this case, the portion of the band 500 that does not enter the entrance port 120 of the band 500 moves poorly due to the decrease in tension. Support 98 supports band 500 at entrance 120 of band 500. Since the band 500 is supported by the support body 98, even if the easily bent portion of the band 500 tries to bend, the bending is suppressed. As a result, bending of the band 500 inside the approach path 122 is suppressed.
　もしくは、上述された支持体９８が、バンド支持面１９０を有していることが望ましい。バンド支持面１９０は、バンド５００の進入口１２０に対向する。 Alternatively, it is desirable that the support body 98 described above has a band support surface 190. Band support surface 190 faces entrance 120 of band 500.
　バンド支持面１９０がバンド５００の進入口１２０に対向すると、バンド５００のうち屈曲しやすくなった部分はそのバンド支持面１９０によって支持されることとなる。バンド５００のうち屈曲しやすくなった部分がバンド支持面１９０によって支持されると、例えば尖ったものによって支持される場合に比べて、その屈曲しやすくなった部分のうち屈曲が抑制される領域は大きくなる。その結果、進入路１２２の内部でのバンド５００の屈曲はより抑制される。 When the band support surface 190 faces the entrance port 120 of the band 500, the easily bent portion of the band 500 will be supported by the band support surface 190. When a part of the band 500 that has become easier to bend is supported by the band support surface 190, compared to, for example, a case where it is supported by a sharp object, the area of the part that has become easier to bend is suppressed from bending. growing. As a result, bending of the band 500 inside the approach path 122 is further suppressed.
　もしくは、上述されたバンド支持面１９０と傾斜対向面１７０とが互いに交差する方向に延びていることが望ましい。 Alternatively, it is desirable that the band support surface 190 and the inclined opposing surface 170 described above extend in a direction that intersects with each other.
　バンド支持面１９０と傾斜対向面１７０とが互いに交差する方向に延びている。これにより、上述された張力の減少とは別に、バンド５００はバンド５００の進入口１２０付近で屈曲することとなる。この屈曲がある場合、そうでない場合に比べて、引っ張られたバンド５００にかかっていた張力が減少することによりそのバンド５００のうちいったん進入路１２２の内部に入った部分が再びチャックベース９０の外へ戻る可能性は低くなる。しかも、押付グリッパ９２は、チャックベース９０のうち傾斜対向面１７０へバンド５００をスライド可能に押し付ける。これにより、バンド５００のうちいったん進入路１２２の内部に入った部分が傾斜対向面１７０をスライドして進入路１２２を通り抜ける可能性が高くなる。その可能性が高くなるので、進入路１２２の内部でのバンド５００の屈曲をより抑制できる。 The band support surface 190 and the inclined opposing surface 170 extend in a direction that intersects with each other. This causes the band 500 to bend near the entry port 120 of the band 500, in addition to the reduction in tension described above. When there is this bending, the tension applied to the pulled band 500 is reduced compared to the case where it is not bent, so that the portion of the band 500 that once entered the inside of the entrance path 122 is returned to the outside of the chuck base 90. less likely to return. Furthermore, the pressing gripper 92 slidably presses the band 500 against the inclined opposing surface 170 of the chuck base 90. This increases the possibility that the portion of the band 500 that has once entered the entrance path 122 will slide on the inclined opposing surface 170 and pass through the entrance path 122. Since this possibility increases, bending of the band 500 inside the approach path 122 can be further suppressed.
　また、上述されたバンド支持部１１２がバンド斜路１７２を傾斜対向面１７０に加えて有することが望ましい。バンド斜路１７２は、バンド５００の進入口１２０に近づくにつれ接触面１３０から離れるよう接触面１３０に対して傾斜している。この場合、バンド斜路１７２がバンド５００の進入口１２０と傾斜対向面１７０とをつなぐことが望ましい。 Furthermore, it is desirable that the band support section 112 described above has a band slope 172 in addition to the slope facing surface 170. The band slope 172 is inclined with respect to the contact surface 130 so as to move away from the contact surface 130 as it approaches the entrance 120 of the band 500. In this case, it is desirable that the band slope 172 connects the entrance 120 of the band 500 and the slope facing surface 170.
　進入口１２０と傾斜対向面１７０とをバンド斜路１７２がつなぐことにより、バンド支持部１１２がバンド斜路１７２を有していない場合に比べ、接触面１３０に対する傾斜対向面１７０の傾きは大きくなる。その傾きが大きくなると、進入路１２２に進入したバンド５００は強く引っ張られることとなる。その結果、本発明にかかるバンド引締装置１０は、バンド５００を引っ張る力を向上させ得る。 By connecting the entrance port 120 and the inclined opposing surface 170 with the band inclined path 172, the inclination of the inclined opposing surface 170 with respect to the contact surface 130 becomes larger than in the case where the band supporting part 112 does not have the band inclined path 172. If the inclination becomes large, the band 500 that has entered the approach path 122 will be strongly pulled. As a result, the band tightening device 10 according to the present invention can improve the force with which the band 500 is pulled.
　本発明は、引締対象となるバンドの範囲を拡大させ得る。 The present invention can expand the range of bands to be tightened.

　マニホールド２１０は、レギュレータ２８に接続されている。マニホールド２１０は、次に述べられる６本の通路を形成する。それらのうち第１の通路は、レギュレータ２８と往復機構用方向制御弁２１２との間の空気通路３１０である。この通路は、図１６においてその空気通路３１０に連なる周知の継手と図示されない管とによって、レギュレータ２８に接続される。それらのうち第２の通路は、往復機構用方向制御弁２１２とグリッピング機構駆動用アクチュエータ２１６との間の一方の空気通路３１２である。それらのうち第３の通路は、往復機構用方向制御弁２１２とグリッピング機構駆動用アクチュエータ２１６との間の他方の空気通路３１４である。それらのうち第４の通路は、往復機構用方向制御弁２１２とグリッピング機構駆動用アクチュエータ２１６との間の他方の空気通路３１４から分岐するものである。以下の説明においてこの通路は分岐通路３１６と称される。この分岐通路３１６は、図１６において分岐通路３１６に連なる周知の継手と図示されない管とによって、スピードコントローラ２１４に接続される。それらのうち第５の通路は、往復機構用方向制御弁２１２に連なる一方の排気通路３５０である。それらのうち第６の通路は、往復機構用方向制御弁２１２に連なる他方の排気通路３５２である。 The manifold 210 is connected to the regulator 28. Manifold 210 forms the six passageways described next. The first of these is an air passage 310 between the regulator 28 and the reciprocating mechanism directional control valve 212. This passage is connected to the regulator 28 in FIG. 16 by a well-known joint and a tube (not shown) which connects to the air passage 310. The second passage among them is one air passage 312 between the reciprocating mechanism directional control valve 212 and the gripping mechanism driving actuator 216. The third passage among them is the other air passage 314 between the reciprocating mechanism directional control valve 212 and the gripping mechanism driving actuator 216.

The fifth passage among them is one exhaust passage 350 that is connected to the reciprocating mechanism directional control valve 212. The sixth passage among them is the other exhaust passage 352 that continues to the reciprocating mechanism directional control valve 212.
　往復機構用方向制御弁２１２は、レギュレータ２８とスピードコントローラ２１４とグリッピング機構駆動用アクチュエータ２１６とにはマニホールド２１０を介して接続されている。往復機構用方向制御弁２１２は、スイッチングレバー付方向制御弁２１８と起動用方向制御弁２２０とにも接続されている。往復機構用方向制御弁２１２は、スイッチングレバー付方向制御弁２１８から供給される空気に応じて、レギュレータ２８から供給されグリッピング機構駆動用アクチュエータ２１６へ供給する空気の通路を切り替える。 The reciprocating mechanism directional control valve 212 is connected to the regulator 28, speed controller 214, and gripping mechanism driving actuator 216 via a manifold 210. The reciprocating mechanism directional control valve 212 is also connected to a switching lever-equipped directional control valve 218 and a starting directional control valve 220 . The reciprocating mechanism directional control valve 212 switches the passage of air supplied from the regulator 28 and supplied to the gripping mechanism driving actuator 216, depending on the air supplied from the switching lever-equipped directional control valve 218.
　スピードコントローラ２１４は、分岐通路３１６を介して往復機構用方向制御弁２１２とグリッピング機構駆動用アクチュエータ２１６とに接続される。また、スピードコントローラ２１４は、後述される往復機構２４とカット機構３０とを連携させるための空気通路３４０を介してカット機構３０に接続される。より具体的には、スピードコントローラ２１４は、後述されるように、カット機構３０のうちカット機構用方向制御弁２８０に接続される。スピードコントローラ２１４は、カット機構用方向制御弁２８０へ空気を供給する。 The speed controller 214 is connected to the reciprocating mechanism directional control valve 212 and the gripping mechanism driving actuator 216 via a branch passage 316. Further, the speed controller 214 is connected to the cutting mechanism 30 via an air passage 340 for cooperating the reciprocating mechanism 24 and the cutting mechanism 30, which will be described later. More specifically, the speed controller 214 is connected to the cutting mechanism directional control valve 280 of the cutting mechanism 30, as will be described later. The speed controller 214 supplies air to the cutting mechanism directional control valve 280.
　グリッピング機構駆動用アクチュエータ２１６は、マニホールド２１０を介して往復機構用方向制御弁２１２に接続される。グリッピング機構駆動用アクチュエータ２１６は、往復リンク２２４を駆動する。本実施形態にかかるグリッピング機構駆動用アクチュエータ２１６は、周知のエアーシリンダによって実現される。 The gripping mechanism driving actuator 216 is connected to the reciprocating mechanism directional control valve 212 via the manifold 210. The gripping mechanism driving actuator 216 drives the reciprocating link 224. The gripping mechanism driving actuator 216 according to this embodiment is realized by a well-known air cylinder.
　スイッチングレバー付方向制御弁２１８は、往復機構用方向制御弁２１２と起動用方向制御弁２２０とに接続される。スイッチングレバー付方向制御弁２１８は、空気の供給により、往復機構用方向制御弁２１２を制御する。本実施形態にかかるスイッチングレバー付方向制御弁２１８は、切替弁本体２４０と、第１スイッチングレバー２４２と、第２スイッチングレバー２４４とを有する。起動用方向制御弁２２０と往復機構用方向制御弁２１２とが直接接続されるのは切替弁本体２４０である。第１スイッチングレバー２４２は、駆動切替ピン２２２によって押されると、切替弁本体２４０における空気の経路を変更する。これにより、図示されない空気導入元から供給された空気が起動用方向制御弁２２０へ流れる。第２スイッチングレバー２４４は、駆動切替ピン２２２によって押されると、切替弁本体２４０における空気の経路を変更する。これにより、図示されない空気導入元から供給された空気が起動用方向制御弁２２０を経由せず往復機構用方向制御弁２１２へ流れる。このように動作するための切替弁本体２４０の構造は周知なので、ここではその詳細な説明は繰り返されない。なお、本実施形態にかかるグリッピング機構駆動用アクチュエータ２１６のストロークは、第１スイッチングレバー２４２が切替弁本体２４０における空気の経路を変更した後には第１スイッチングレバー２４２を押し続けないものとなっている。また、本実施形態にかかるグリッピング機構駆動用アクチュエータ２１６のストロークは、第２スイッチングレバー２４４が切替弁本体２４０における空気の経路を変更した後には第２スイッチングレバー２４４を押し続けないものとなっている。これにより、第１スイッチングレバー２４２と第２スイッチングレバー２４４との破損が予防されている。 The switching lever equipped directional control valve 218 is connected to the reciprocating mechanism directional control valve 212 and the starting directional control valve 220. The switching lever equipped directional control valve 218 controls the reciprocating mechanism directional control valve 212 by supplying air. The switching lever-equipped directional control valve 218 according to this embodiment includes a switching valve main body 240, a first switching lever 242, and a second switching lever 244. The starting directional control valve 220 and the reciprocating mechanism directional control valve 212 are directly connected to the switching valve body 240. The first switching lever 242 changes the air path in the switching valve body 240 when pushed by the drive switching pin 222 . As a result, air supplied from an air introduction source (not shown) flows to the activation directional control valve 220. The second switching lever 244 changes the air path in the switching valve body 240 when pushed by the drive switching pin 222 . As a result, air supplied from an air introduction source (not shown) flows to the reciprocating mechanism directional control valve 212 without passing through the starting directional control valve 220. Since the structure of the switching valve body 240 for operating in this manner is well known, detailed description thereof will not be repeated here. Note that the stroke of the gripping mechanism driving actuator 216 according to the present embodiment is such that the first switching lever 242 is not kept pressed after the first switching lever 242 changes the air path in the switching valve body 240. . Further, the stroke of the gripping mechanism driving actuator 216 according to the present embodiment is such that the second switching lever 244 is not kept pressed after the second switching lever 244 changes the air path in the switching valve body 240. . This prevents damage to the first switching lever 242 and the second switching lever 244.
　起動用方向制御弁２２０は、スイッチングレバー付方向制御弁２１８と往復機構用方向制御弁２１２とに接続される。本実施形態にかかる起動用方向制御弁２２０は、スタートボタン２５０と、起動弁本体２５２とを有する。スタートボタン２５０は、これが受けた力を起動弁本体２５２に伝える。起動弁本体２５２は、スタートボタン２５０から力を伝えられると、次に述べられる空気通路３２２を開く。その空気通路３２２は、往復機構用方向制御弁２１２とスイッチングレバー付方向制御弁２１８との間の起動用方向制御弁２２０を経由する空気通路３２２である。起動弁本体２５２は、スタートボタン２５０から力を伝えられなくなると、その空気通路３２２を閉じる。 The starting directional control valve 220 is connected to the switching lever-equipped directional control valve 218 and the reciprocating mechanism directional control valve 212. The starting directional control valve 220 according to this embodiment includes a start button 250 and a starting valve body 252. The start button 250 transmits the force it receives to the starting valve body 252. When the start valve body 252 receives a force from the start button 250, it opens an air passage 322, which will be described next. The air passage 322 is an air passage 322 that passes through the activation directional control valve 220 between the reciprocating mechanism directional control valve 212 and the switching lever equipped directional control valve 218. Start valve body 252 closes its air passage 322 when force is no longer transmitted from start button 250 .
　駆動切替ピン２２２は、グリッピング機構駆動用アクチュエータ２１６と往復リンク２２４とを連結する。さらに、駆動切替ピン２２２は、スイッチングレバー付方向制御弁２１８の第１スイッチングレバー２４２と第２スイッチングレバー２４４とを押す。 The drive switching pin 222 connects the gripping mechanism drive actuator 216 and the reciprocating link 224. Further, the drive switching pin 222 pushes the first switching lever 242 and the second switching lever 244 of the directional control valve 218 with a switching lever.
　往復リンク２２４は、グリッピング機構駆動用アクチュエータ２１６が供給する動力をグリッピング機構２２へ伝達する。 The reciprocating link 224 transmits the power supplied by the gripping mechanism driving actuator 216 to the gripping mechanism 22.
　往復リンク揺動中心ピン２２６は、往復リンク２２４を揺動自在に固定する。これにより、往復リンク２２４はグリッピング機構駆動用アクチュエータ２１６が供給する動力に応じて揺動することとなる。なお、往復リンク揺動中心ピン２２６自身は、ハウジング本体５０の収容部７０に固定されている。 The reciprocating link swing center pin 226 swingably fixes the reciprocating link 224. As a result, the reciprocating link 224 swings in response to the power supplied by the gripping mechanism drive actuator 216. Note that the reciprocating link swing center pin 226 itself is fixed to the accommodating portion 70 of the housing body 50.
　グリッピング機構連結ピン２２８は、往復リンク２２４をチャックベース９０の形成壁１１０，１１０の対に接続する。本実施形態の場合、グリッピング機構連結ピン２２８は、チャックベース９０の連結ピン貫通孔１５４，１５４を貫通する。さらに、グリッピング機構連結ピン２２８は、往復リンク２２４の一端の溝に嵌まる。これにより、往復リンク２２４の揺動に伴ってグリッピング機構２２は往復運動をするよう駆動されることとなる。 A gripping mechanism connecting pin 228 connects the reciprocating link 224 to the pair of forming walls 110, 110 of the chuck base 90. In the case of this embodiment, the gripping mechanism connecting pin 228 passes through the connecting pin through holes 154, 154 of the chuck base 90. Furthermore, the gripping mechanism coupling pin 228 fits into a groove in one end of the reciprocating link 224. As a result, the gripping mechanism 22 is driven to reciprocate as the reciprocating link 224 swings.

FIG. 18 is a perspective view of the return suppressing gripper 262 and the gripper pressing lever 264 according to this embodiment. FIG. 19 is a sectional view of the return suppression mechanism 26 according to this embodiment. The configuration of the return suppression mechanism 26 according to this embodiment will be explained based on FIGS. 17 to 19.
　本実施形態にかかる戻り抑制機構２６は、ロックベース２６０と、戻り抑制グリッパ２６２と、グリッパ押付レバー２６４と、押付用コイルバネ２６６と、レバー揺動中心ピン２６８とを有している。 The return suppression mechanism 26 according to this embodiment includes a lock base 260, a return suppression gripper 262, a gripper pressing lever 264, a pressing coil spring 266, and a lever swing center pin 268.
　本実施形態の場合、ロックベース２６０は、ハウジング本体５０の戻り抑制機構固定部７４に固定される。ロックベース２６０は、戻り抑制グリッパ２６２が収容されバンド５００が貫通する空間を形成する。ロックベース２６０には、戻り抑制グリッパ嵌込長孔２７０，２７０の対が形成されている。戻り抑制グリッパ２６２の両端はそれら戻り抑制グリッパ嵌込長孔２７０，２７０の対に嵌まっている。戻り抑制グリッパ２６２は、ロックベース２６０内をバンド５００が貫通しているとき、ロックベース２６０の内周面へそのバンド５００を押し付ける。グリッパ押付レバー２６４は、戻り抑制グリッパ２６２を押す。押付用コイルバネ２６６の一端は、ハウジング本体５０の内部に設けられたバネ支持板７６に載せられている。押付用コイルバネ２６６の他端は、グリッパ押付レバー２６４を押す。レバー揺動中心ピン２６８は、ロックベース２６０を貫通する。レバー揺動中心ピン２６８は、グリッパ押付レバー２６４を揺動自在に固定する。 In the case of this embodiment, the lock base 260 is fixed to the return suppression mechanism fixing part 74 of the housing main body 50. The lock base 260 forms a space in which the return restraining gripper 262 is accommodated and through which the band 500 passes. A pair of elongated holes 270, 270 are formed in the lock base 260 to fit the return suppressing gripper. Both ends of the anti-return gripper 262 are fitted into a pair of elongated holes 270, 270 for receiving the anti-return gripper. The return suppressing gripper 262 presses the band 500 against the inner peripheral surface of the lock base 260 when the band 500 passes through the lock base 260. The gripper pressing lever 264 presses the return suppression gripper 262 . One end of the pressing coil spring 266 is placed on a spring support plate 76 provided inside the housing body 50. The other end of the pressing coil spring 266 presses the gripper pressing lever 264. The lever swing center pin 268 passes through the lock base 260. The lever swing center pin 268 swingably fixes the gripper pressing lever 264.
　押付用コイルバネ２６６の他端がグリッパ押付レバー２６４を押すと、グリッパ押付レバー２６４はレバー揺動中心ピン２６８を中心に揺動する。揺動したグリッパ押付レバー２６４は、上述されたように、戻り抑制グリッパ２６２を押す。押された戻り抑制グリッパ２６２の両端はロックベース２６０に形成されている戻り抑制グリッパ嵌込長孔２７０に嵌まっている。これにより、押された戻り抑制グリッパ２６２は戻り抑制グリッパ嵌込長孔２７０に沿って押し上げられる。その際、ロックベース２６０の内部をバンド５００が貫通していると、押し上げられた戻り抑制グリッパ２６２はロックベース２６０の内周面へバンド５００を押し付けることとなる。 When the other end of the pressing coil spring 266 presses the gripper pressing lever 264, the gripper pressing lever 264 swings around the lever swing center pin 268. The swung gripper pressing lever 264 presses the return suppressing gripper 262 as described above. Both ends of the pressed return-preventing gripper 262 are fitted into return-preventing gripper fitting elongated holes 270 formed in the lock base 260. As a result, the pushed return prevention gripper 262 is pushed up along the return prevention gripper insertion elongated hole 270. At this time, if the band 500 penetrates the inside of the lock base 260, the pushed-up return suppressing gripper 262 will press the band 500 against the inner peripheral surface of the lock base 260.

The configuration of the cutting mechanism 30 according to this embodiment will be explained based on FIG. 20. Although not shown in FIG. 20, the cutting mechanism directional control valve 280 and the cutting mechanism driving actuator 282 are connected to each other by a pipe for passing air. How these are connected is explained below.
　本実施形態にかかるカット機構３０は、カット機構用方向制御弁２８０と、カット機構駆動用アクチュエータ２８２と、アクチュエータ連結ピン２８４と、伝達リンク２８６，２８６の対と、リンク連結ピン２８８と、揺動リンク２９０と、揺動中心ピン２９２と、カッタ本体連結ピン２９４と、カッタ本体２９６と、カッタガイド２９８とを有している。 The cutting mechanism 30 according to the present embodiment includes a cutting mechanism directional control valve 280, a cutting mechanism driving actuator 282, an actuator connecting pin 284, a pair of transmission links 286, 286, a link connecting pin 288, and a swinging mechanism.

The cut mechanism directional control valve 280 controls the direction in which air supplied from an air introduction source (not shown) flows. This control is performed depending on the air supplied from the speed controller 214.
　カット機構駆動用アクチュエータ２８２は、カッタ本体２９６を往復させるための動力を供給する。カット機構駆動用アクチュエータ２８２は、図示されない空気導入元から供給される空気により駆動される。その空気が流れる方向は、カット機構用方向制御弁２８０により制御される。本実施形態の場合、カット機構駆動用アクチュエータ２８２は空気によって駆動される周知のアクチュエータである。 The cutting mechanism driving actuator 282 supplies power for reciprocating the cutter body 296. The cutting mechanism driving actuator 282 is driven by air supplied from an air introduction source (not shown). The direction in which the air flows is controlled by the cutting mechanism directional control valve 280. In the case of this embodiment, the cutting mechanism driving actuator 282 is a well-known actuator driven by air.
　アクチュエータ連結ピン２８４は、カット機構駆動用アクチュエータ２８２と伝達リンク２８６，２８６の対とを連結する。 The actuator connecting pin 284 connects the cutting mechanism driving actuator 282 and the pair of transmission links 286, 286.
　伝達リンク２８６，２８６の対は、カット機構駆動用アクチュエータ２８２が供給する動力を揺動リンク２９０へ伝達する。 The pair of transmission links 286 , 286 transmits the power supplied by the cutting mechanism driving actuator 282 to the swing link 290 .
　リンク連結ピン２８８は、伝達リンク２８６，２８６の対と揺動リンク２９０とを連結する。 The link connecting pin 288 connects the pair of transmission links 286, 286 and the swing link 290.
　揺動リンク２９０は、伝達リンク２８６，２８６の対から伝達された動力をカッタ本体２９６へ伝達する。 The swing link 290 transmits the power transmitted from the pair of transmission links 286, 286 to the cutter body 296.
　揺動中心ピン２９２は、ロックベース２６０に形成された孔を貫通している。これにより、揺動中心ピン２９２は、戻り抑制機構２６に固定されることとなる。揺動中心ピン２９２は、揺動リンク２９０を揺動自在に固定する。これにより、揺動リンク２９０はカット機構駆動用アクチュエータ２８２が供給する動力に応じて揺動することとなる。 The swing center pin 292 passes through a hole formed in the lock base 260. Thereby, the swing center pin 292 is fixed to the return suppression mechanism 26. The swing center pin 292 swingably fixes the swing link 290. As a result, the swing link 290 swings in response to the power supplied by the cutting mechanism drive actuator 282.
　カッタ本体連結ピン２９４は、揺動リンク２９０とカッタ本体２９６とを連結する。 The cutter body connecting pin 294 connects the swing link 290 and the cutter body 296.
　カッタ本体２９６は、揺動リンク２９０によって押し上げられバンド５００に押し当てられると、そのバンド５００をカットする。 When the cutter body 296 is pushed up by the swing link 290 and pressed against the band 500, it cuts the band 500.
　カッタガイド２９８は、ロックベース２６０に固定される。カッタガイド２９８には図示されない凹部が形成されている。カッタ本体２９６はその凹部に嵌まったまま昇降可能である。これにより、カッタガイド２９８は、揺動リンク２９０によって押し上げられるカッタ本体２９６の移動方向を規制することとなる。その結果、カッタ本体２９６は揺動リンク２９０の動きに応じて上下運動をすることとなる。 The cutter guide 298 is fixed to the lock base 260. A recess (not shown) is formed in the cutter guide 298. The cutter body 296 can be moved up and down while being fitted into the recess. Thereby, the cutter guide 298 restricts the moving direction of the cutter body 296 pushed up by the swing link 290. As a result, the cutter body 296 moves up and down in accordance with the movement of the swing link 290.

　本実施形態にかかるバンド引締装置１０に図示されない空気導入元から空気が供給されると、その空気の一部はレギュレータ２８に送られる。その空気の別の一部はスイッチングレバー付方向制御弁２１８に送られる。その空気のさらに別の一部はカット機構用方向制御弁２８０に送られる。空気が供給されたレギュレータ２８はその空気の圧力を所定の圧力に調整する。その空気は、往復機構用方向制御弁２１２に供給される。レギュレータ２８から往復機構用方向制御弁２１２への空気の供給は、これらの間の空気通路３１０を経由する。図示されない空気導入元からスイッチングレバー付方向制御弁２１８への空気の供給は、これらの間の空気通路３２０を経由する。図示されない空気導入元からカット機構用方向制御弁２８０への空気の供給は、これらの間の空気通路３３０を経由する。 When air is supplied to the band tightening device 10 according to the present embodiment from an air introduction source (not shown), a portion of the air is sent to the regulator 28. Another part of the air is sent to a directional control valve 218 with a switching lever. Still another portion of the air is sent to the cutting mechanism directional control valve 280. The regulator 28 supplied with air adjusts the pressure of the air to a predetermined pressure. The air is supplied to the reciprocating mechanism directional control valve 212. Air is supplied from the regulator 28 to the reciprocating mechanism directional control valve 212 via an air passage 310 between them. Air is supplied from an air introduction source (not shown) to the switching lever equipped directional control valve 218 via an air passage 320 between them. Air is supplied from an air introduction source (not shown) to the cutting mechanism directional control valve 280 via an air passage 330 between them.
　往復機構用方向制御弁２１２に供給された空気は、グリッピング機構駆動用アクチュエータ２１６に供給される。ここでは、その空気が、往復機構用方向制御弁２１２とグリッピング機構駆動用アクチュエータ２１６との間の他方の空気通路３１４を経由することとする。そのように空気が供給されると、グリッピング機構駆動用アクチュエータ２１６が往復リンク２２４を引っ張るようになる。 The air supplied to the reciprocating mechanism directional control valve 212 is supplied to the gripping mechanism driving actuator 216. Here, the air passes through the other air passage 314 between the reciprocating mechanism directional control valve 212 and the gripping mechanism driving actuator 216. Such supply of air causes the gripping mechanism drive actuator 216 to pull on the reciprocating link 224.
　カット機構用方向制御弁２８０に供給された空気は、カット機構駆動用アクチュエータ２８２に供給される。ここでは、その空気が、カット機構用方向制御弁２８０とカット機構駆動用アクチュエータ２８２のシリンダのピストン貫通部付近との間の空気通路３３２を経由することとする。このとき、カット機構用方向制御弁２８０とカット機構駆動用アクチュエータ２８２のシリンダ底部付近との間の空気通路３３４において、カット機構駆動用アクチュエータ２８２からカット機構用方向制御弁２８０へ空気が流れる。その空気はカット機構用方向制御弁２８０を経由して大気中へ排出される。これにより、カット機構駆動用アクチュエータ２８２のピストンはシリンダ内に収容される。 The air supplied to the cutting mechanism directional control valve 280 is supplied to the cutting mechanism driving actuator 282. Here, the air passes through the air passage 332 between the cutting mechanism directional control valve 280 and the vicinity of the piston penetration portion of the cylinder of the cutting mechanism driving actuator 282. At this time, air flows from the cutting mechanism driving actuator 282 to the cutting mechanism directional control valve 280 in the air passage 334 between the cutting mechanism driving actuator 280 and the vicinity of the cylinder bottom of the cutting mechanism driving actuator 282. The air is discharged into the atmosphere via the cut mechanism directional control valve 280. As a result, the piston of the cutting mechanism driving actuator 282 is housed in the cylinder.
　予め、バンド５００はあるものに巻き付けられている。そのバンド５００が巻き付けられるものは図示されていない。このバンド５００の先端が引き締められると、そのバンド５００が巻き付けられるものはバンド５００により縛られることとなる。作業者は、本実施形態にかかるバンド引締装置１０のカッタガイド２９８の上にバンド５００の先端を載せる。バンド５００の先端が載せられると、作業者はそのままそのバンド５００の先端を本実施形態にかかるバンド引締装置１０の内部に押し込む。これにより、そのバンド５００の先端はロックベース２６０内を貫通する。ロックベース２６０内を貫通したバンド５００の先端は、チャックベース９０に形成されている進入口１２０を通過する。進入口１２０を通過したバンド５００の先端は、進入路１２２を貫通する。バンド進入防止部１１４は、進入路１２２を貫通したバンド５００の先端が本実施形態にかかるバンド引締装置１０の内部へ進入することを妨げる。その結果、進入路１２２を貫通したバンド５００の先端は、本実施形態にかかるバンド引締装置１０の外へ出る。 The band 500 is wrapped around something in advance. What the band 500 is wrapped around is not shown. When the tip of the band 500 is tightened, the object to which the band 500 is wrapped is bound by the band 500. The operator places the tip of the band 500 on the cutter guide 298 of the band tightening device 10 according to this embodiment. When the tip of the band 500 is placed, the operator directly pushes the tip of the band 500 into the inside of the band tightening device 10 according to this embodiment. As a result, the tip of the band 500 penetrates inside the lock base 260. The tip of the band 500 that has passed through the lock base 260 passes through the entrance port 120 formed in the chuck base 90. The tip of the band 500 that has passed through the entrance 120 passes through the entrance path 122 . The band entry prevention portion 114 prevents the tip of the band 500 that has passed through the entry path 122 from entering the inside of the band tightening device 10 according to this embodiment. As a result, the tip of the band 500 that has passed through the entrance path 122 comes out of the band tightening device 10 according to this embodiment.
　次いで、作業者は、本実施形態にかかるバンド引締装置１０のスタートボタン２５０を押す。スタートボタン２５０が押されると、起動用方向制御弁２２０の起動弁本体２５２が開く。上述されたように、図示されない空気導入元からスイッチングレバー付方向制御弁２１８へ空気が供給されている。これにより、起動用方向制御弁２２０の起動弁本体２５２が開くと、スイッチングレバー付方向制御弁２１８から往復機構用方向制御弁２１２に空気が供給される。その空気は、往復機構用方向制御弁２１２とスイッチングレバー付方向制御弁２１８との間の起動用方向制御弁２２０を経由する空気通路３２２を経る。スイッチングレバー付方向制御弁２１８から往復機構用方向制御弁２１２に空気が供給されると、往復機構用方向制御弁２１２からグリッピング機構駆動用アクチュエータ２１６へ供給される空気の流れが変わる。往復機構用方向制御弁２１２がそのように空気の流れを変える。これにより、往復機構用方向制御弁２１２からグリッピング機構駆動用アクチュエータ２１６へ空気が流れる。その空気は、往復機構用方向制御弁２１２とグリッピング機構駆動用アクチュエータ２１６との間の一方の空気通路３１２を経由する。グリッピング機構駆動用アクチュエータ２１６から往復機構用方向制御弁２１２へ空気が流れる。その空気は、往復機構用方向制御弁２１２とグリッピング機構駆動用アクチュエータ２１６との間の他方の空気通路３１４を経由する。その結果、グリッピング機構駆動用アクチュエータ２１６が往復リンク２２４を押すようになる。 Next, the operator presses the start button 250 of the band tightening device 10 according to this embodiment. When the start button 250 is pressed, the starting valve main body 252 of the starting directional control valve 220 opens. As described above, air is supplied to the switching lever-equipped directional control valve 218 from an air introduction source (not shown). As a result, when the starting valve main body 252 of the starting directional control valve 220 opens, air is supplied from the switching lever-equipped directional control valve 218 to the reciprocating mechanism directional control valve 212. The air passes through an air passage 322 that passes through the activation directional control valve 220 between the reciprocating mechanism directional control valve 212 and the switching lever-equipped directional control valve 218. When air is supplied from the switching lever-equipped directional control valve 218 to the reciprocating mechanism directional control valve 212, the flow of air supplied from the reciprocating mechanism directional control valve 212 to the gripping mechanism driving actuator 216 changes. The reciprocating mechanism directional control valve 212 thus changes the air flow. As a result, air flows from the reciprocating mechanism directional control valve 212 to the gripping mechanism driving actuator 216. The air passes through one air passage 312 between the reciprocating mechanism directional control valve 212 and the gripping mechanism driving actuator 216. Air flows from the gripping mechanism driving actuator 216 to the reciprocating mechanism directional control valve 212. The air passes through the other air passage 314 between the reciprocating mechanism directional control valve 212 and the gripping mechanism driving actuator 216. As a result, the gripping mechanism driving actuator 216 pushes the reciprocating link 224.
　往復リンク揺動中心ピン２２６は、往復リンク２２４を揺動自在に固定する。これにより、往復リンク２２４はグリッピング機構駆動用アクチュエータ２１６に押されることに応じて揺動する。往復リンク２２４はグリッピング機構連結ピン２２８を介してチャックベース９０に接続されている。往復リンク２２４がチャックベース９０に接続されているので、チャックベース９０は往復リンク２２４に引っ張られる。往復リンク２２４に引っ張られたチャックベース９０はスライド面７２上を滑る。 The reciprocating link swing center pin 226 swingably fixes the reciprocating link 224. Thereby, the reciprocating link 224 swings in response to being pushed by the gripping mechanism driving actuator 216. The reciprocating link 224 is connected to the chuck base 90 via a gripping mechanism connecting pin 228. Since the reciprocating link 224 is connected to the chuck base 90, the chuck base 90 is pulled by the reciprocating link 224. The chuck base 90 pulled by the reciprocating link 224 slides on the slide surface 72.
　図２２は、バンド５００が引っ張られている際のグリッピング機構２２の断面図である。チャックベース９０がスライド面７２上を滑ると、チャックベース９０内を貫通したバンド５００はチャックベース９０に引っ張られる。これにより、グリッピング機構２２は、スライド面７２に沿った往復に伴ってバンド５００を引っ張ることとなる。 FIG. 22 is a cross-sectional view of the gripping mechanism 22 when the band 500 is being stretched. When the chuck base 90 slides on the slide surface 72, the band 500 passing through the chuck base 90 is pulled by the chuck base 90. Thereby, the gripping mechanism 22 pulls the band 500 as it reciprocates along the slide surface 72.
　その後、グリッピング機構駆動用アクチュエータ２１６に取付けられている駆動切替ピン２２２がスイッチングレバー付方向制御弁２１８の第２スイッチングレバー２４４を押す。駆動切替ピン２２２がスイッチングレバー付方向制御弁２１８の第２スイッチングレバー２４４を押すと、スイッチングレバー付方向制御弁２１８内の空気の流れが変わる。これにより、往復機構用方向制御弁２１２とスイッチングレバー付方向制御弁２１８との間の起動用方向制御弁２２０を経由する空気通路３２２での空気の供給が遮断される。スイッチングレバー付方向制御弁２１８からの空気は、往復機構用方向制御弁２１２とスイッチングレバー付方向制御弁２１８との間の起動用方向制御弁２２０を経由しない空気通路３２４を経て供給されることとなる。このように空気が供給されると、往復機構用方向制御弁２１２は、グリッピング機構駆動用アクチュエータ２１６に供給する空気の流れを変える。これにより、グリッピング機構駆動用アクチュエータ２１６から往復機構用方向制御弁２１２へ空気が排出される。その空気は、往復機構用方向制御弁２１２とグリッピング機構駆動用アクチュエータ２１６との間の一方の空気通路３１２を経由する。往復機構用方向制御弁２１２へ排出された空気は、大気中へ排出される。一方、往復機構用方向制御弁２１２からグリッピング機構駆動用アクチュエータ２１６へ空気が供給される。その空気は、往復機構用方向制御弁２１２とグリッピング機構駆動用アクチュエータ２１６との間の他方の空気通路３１４を経由する。そのように空気が供給されると、グリッピング機構駆動用アクチュエータ２１６が往復リンク２２４を引っ張るようになる。 Thereafter, the drive switching pin 222 attached to the gripping mechanism drive actuator 216 pushes the second switching lever 244 of the directional control valve with switching lever 218. When the drive switching pin 222 pushes the second switching lever 244 of the directional control valve 218 with a switching lever, the flow of air inside the directional control valve 218 with a switching lever changes. As a result, the supply of air in the air passage 322 via the activation directional control valve 220 between the reciprocating mechanism directional control valve 212 and the switching lever equipped directional control valve 218 is cut off. The air from the switching lever-equipped directional control valve 218 is supplied through an air passage 324 between the reciprocating mechanism directional control valve 212 and the switching lever-equipped directional control valve 218 without passing through the starting directional control valve 220. Become. When air is supplied in this way, the reciprocating mechanism directional control valve 212 changes the flow of air supplied to the gripping mechanism driving actuator 216. As a result, air is discharged from the gripping mechanism driving actuator 216 to the reciprocating mechanism directional control valve 212. The air passes through one air passage 312 between the reciprocating mechanism directional control valve 212 and the gripping mechanism driving actuator 216. The air discharged to the reciprocating mechanism directional control valve 212 is discharged into the atmosphere. On the other hand, air is supplied from the reciprocating mechanism directional control valve 212 to the gripping mechanism driving actuator 216. The air passes through the other air passage 314 between the reciprocating mechanism directional control valve 212 and the gripping mechanism driving actuator 216. Such supply of air causes the gripping mechanism drive actuator 216 to pull on the reciprocating link 224.
　上述されたように、往復リンク２２４がチャックベース９０に接続されているので、グリッピング機構駆動用アクチュエータ２１６が往復リンク２２４を引っ張ると、チャックベース９０は往復リンク２２４に押されるようになる。図２２において二点鎖線で示されたように、押されたチャックベース９０はスライド面７２上を滑ってロックベース２６０に近づく。支持体９８はロックベース２６０内に進入する。チャックベース９０がロックベース２６０に近づくと、チャックベース９０を貫通したバンド５００にかかる張力は小さくなる。その際、図２２において二点鎖線で示されたように、戻り抑制機構２６の戻り抑制グリッパ２６２がロックベース２６０の内周面へそのバンド５００を押し付ける。これにより、いったんロックベース２６０内を通過したバンド５００がまたロックベース２６０内へ戻ることが防止される。 As described above, since the reciprocating link 224 is connected to the chuck base 90, when the gripping mechanism driving actuator 216 pulls the reciprocating link 224, the chuck base 90 is pushed by the reciprocating link 224. As shown by the two-dot chain line in FIG. 22, the pushed chuck base 90 slides on the slide surface 72 and approaches the lock base 260. Support 98 enters lock base 260 . When the chuck base 90 approaches the lock base 260, the tension applied to the band 500 passing through the chuck base 90 becomes smaller. At this time, as shown by the two-dot chain line in FIG. 22, the return suppression gripper 262 of the return suppression mechanism 26 presses the band 500 against the inner peripheral surface of the lock base 260. This prevents the band 500, which has once passed through the lock base 260, from returning back into the lock base 260.
　上述されたように、このとき、戻り抑制グリッパ２６２がロックベース２６０の内周面へバンド５００を押し付けている。チャックベース９０内の進入路１２２を貫通したバンド５００にかかる張力は小さくなっている。これにより、チャックベース９０の進入口１２０付近でバンド５００がたるみ易くなっている。チャックベース９０の進入口１２０付近でたるんだバンド５００は支持体９８のバンド支持面１９０により支持される。バンド支持面１９０に支持されたバンド５００はそのバンド支持面１９０から反力を受けて進入路１２２を進む。進んだバンド５００は進入路１２２から押し出される。 As described above, at this time, the return suppressing gripper 262 presses the band 500 against the inner peripheral surface of the lock base 260. The tension applied to the band 500 that has passed through the entrance path 122 in the chuck base 90 is reduced. This makes it easy for the band 500 to become slack near the entrance port 120 of the chuck base 90. The band 500 sagging near the entrance 120 of the chuck base 90 is supported by the band support surface 190 of the support 98 . The band 500 supported by the band support surface 190 receives a reaction force from the band support surface 190 and advances through the approach path 122 . The advanced band 500 is pushed out of the approach path 122.
　その後、グリッピング機構駆動用アクチュエータ２１６に取付けられている駆動切替ピン２２２がスイッチングレバー付方向制御弁２１８の第１スイッチングレバー２４２を押す。駆動切替ピン２２２がスイッチングレバー付方向制御弁２１８の第１スイッチングレバー２４２を押すと、スイッチングレバー付方向制御弁２１８内の空気の流れが変わる。これにより、往復機構用方向制御弁２１２とスイッチングレバー付方向制御弁２１８との間の起動用方向制御弁２２０を経由する空気通路３２２での空気の供給が再開される。往復機構用方向制御弁２１２とスイッチングレバー付方向制御弁２１８との間の起動用方向制御弁２２０を経由しない空気通路３２４での空気の供給は遮断される。そのように空気が供給されると、往復機構用方向制御弁２１２は、グリッピング機構駆動用アクチュエータ２１６に供給する空気の流れを変える。これにより、グリッピング機構駆動用アクチュエータ２１６から往復機構用方向制御弁２１２へ空気が排出される。その空気は、往復機構用方向制御弁２１２とグリッピング機構駆動用アクチュエータ２１６との間の他方の空気通路３１４を経由する。往復機構用方向制御弁２１２へ排出された空気は、大気中へ排出される。一方、往復機構用方向制御弁２１２からグリッピング機構駆動用アクチュエータ２１６へ空気が供給される。その空気は、往復機構用方向制御弁２１２とグリッピング機構駆動用アクチュエータ２１６との間の一方の空気通路３１２を経由する。これにより、グリッピング機構駆動用アクチュエータ２１６が往復リンク２２４を押すようになる。以下、同様にしてバンド５００の引張と進入路１２２からのバンド５００の押し出しとが繰り返される。その結果、往復機構２４は、スライド面７２に沿ってグリッピング機構２２を往復させることとなる。 Thereafter, the drive switching pin 222 attached to the gripping mechanism drive actuator 216 pushes the first switching lever 242 of the directional control valve with switching lever 218. When the drive switching pin 222 pushes the first switching lever 242 of the directional control valve 218 with a switching lever, the flow of air inside the directional control valve 218 with a switching lever changes. As a result, the supply of air in the air passage 322 via the activation directional control valve 220 between the reciprocating mechanism directional control valve 212 and the switching lever equipped directional control valve 218 is restarted. The supply of air in the air passage 324 between the reciprocating mechanism directional control valve 212 and the switching lever equipped directional control valve 218 without passing through the activation directional control valve 220 is cut off. When air is supplied in this way, the reciprocating mechanism directional control valve 212 changes the flow of air supplied to the gripping mechanism driving actuator 216. As a result, air is discharged from the gripping mechanism driving actuator 216 to the reciprocating mechanism directional control valve 212. The air passes through the other air passage 314 between the reciprocating mechanism directional control valve 212 and the gripping mechanism driving actuator 216. The air discharged to the reciprocating mechanism directional control valve 212 is discharged into the atmosphere. On the other hand, air is supplied from the reciprocating mechanism directional control valve 212 to the gripping mechanism driving actuator 216. The air passes through one air passage 312 between the reciprocating mechanism directional control valve 212 and the gripping mechanism driving actuator 216. This causes the gripping mechanism driving actuator 216 to push the reciprocating link 224. Thereafter, the tensioning of the band 500 and the pushing out of the band 500 from the approach path 122 are repeated in the same manner. As a result, the reciprocating mechanism 24 causes the gripping mechanism 22 to reciprocate along the slide surface 72.
　その後、バンド５００が十分に引き締められると、グリッピング機構駆動用アクチュエータ２１６が往復リンク２２４を押し出せなくなる。グリッピング機構駆動用アクチュエータ２１６が往復リンク２２４を押し出せなくなった後も、往復機構用方向制御弁２１２とグリッピング機構駆動用アクチュエータ２１６との間の他方の空気通路３１４から空気が排出される。この排出により、分岐通路３１６、および、往復機構２４とカット機構３０とを連携させるための空気通路３４０においても、空気が排出される。 Thereafter, when the band 500 is sufficiently tightened, the gripping mechanism driving actuator 216 will no longer be able to push out the reciprocating link 224. Even after the gripping mechanism driving actuator 216 is no longer able to push out the reciprocating link 224, air is exhausted from the other air passage 314 between the reciprocating mechanism directional control valve 212 and the gripping mechanism driving actuator 216. Due to this discharge, air is also discharged from the branch passage 316 and the air passage 340 for cooperating the reciprocating mechanism 24 and the cutting mechanism 30.
　そのように空気が排出されると、カット機構用方向制御弁２８０は、カット機構駆動用アクチュエータ２８２へ供給する空気の流れを変える。これにより、カット機構用方向制御弁２８０からカット機構駆動用アクチュエータ２８２に供給される空気は、カット機構用方向制御弁２８０とカット機構駆動用アクチュエータ２８２のシリンダ底部付近との間の空気通路３３４を経由することとなる。カット機構用方向制御弁２８０とカット機構駆動用アクチュエータ２８２のシリンダのピストン貫通部付近との間の空気通路３３２からは、空気が排出されることとなる。その空気はカット機構用方向制御弁２８０を経由して大気中へ排出される。 When the air is discharged in this way, the cutting mechanism directional control valve 280 changes the flow of air supplied to the cutting mechanism driving actuator 282. As a result, the air supplied from the cutting mechanism directional control valve 280 to the cutting mechanism driving actuator 282 flows through the air passage 334 between the cutting mechanism directional control valve 280 and the vicinity of the cylinder bottom of the cutting mechanism driving actuator 282. I will go through it. Air is discharged from the air passage 332 between the cutting mechanism directional control valve 280 and the vicinity of the piston penetration portion of the cylinder of the cutting mechanism driving actuator 282. The air is discharged into the atmosphere via the cut mechanism directional control valve 280.
　これにより、カット機構駆動用アクチュエータ２８２は伝達リンク２８６，２８６の対を押す。伝達リンク２８６，２８６の対は、カット機構駆動用アクチュエータ２８２が供給する動力を揺動リンク２９０へ伝達する。揺動リンク２９０は、伝達リンク２８６，２８６の対から伝達された動力をカッタ本体２９６へ伝達する。カッタ本体２９６は、揺動リンク２９０によって押し上げられバンド５００に押し当てられると、そのバンド５００をカットする。 As a result, the cutting mechanism driving actuator 282 pushes the pair of transmission links 286, 286. The pair of transmission links 286 , 286 transmits the power supplied by the cutting mechanism driving actuator 282 to the swing link 290 . Swing link 290 transmits the power transmitted from the pair of transmission links 286 , 286 to cutter body 296 . When the cutter body 296 is pushed up by the swing link 290 and pressed against the band 500, it cuts the band 500.
　バンド５００がカットされると、作業者はスタートボタン２５０から手を離す。これにより、往復機構用方向制御弁２１２とスイッチングレバー付方向制御弁２１８との間の起動用方向制御弁２２０を経由する空気通路３２２での空気の供給が停止する。このとき、グリッピング機構駆動用アクチュエータ２１６が往復リンク２２４を押している途中となっている。そのため、グリッピング機構駆動用アクチュエータ２１６は引き続き動作する。その後、駆動切替ピン２２２がスイッチングレバー付方向制御弁２１８の第２スイッチングレバー２４４を押すと、スイッチングレバー付方向制御弁２１８内の空気の流れが変わる。これにより、グリッピング機構駆動用アクチュエータ２１６が往復リンク２２４を引っ張るようになる。その結果、往復機構用方向制御弁２１２とグリッピング機構駆動用アクチュエータ２１６との間の他方の空気通路３１４を経由して、グリッピング機構駆動用アクチュエータ２１６へ空気が供給される。 Once the band 500 is cut, the operator releases the start button 250. As a result, the supply of air in the air passage 322 via the activation directional control valve 220 between the reciprocating mechanism directional control valve 212 and the switching lever equipped directional control valve 218 is stopped. At this time, the gripping mechanism driving actuator 216 is in the middle of pushing the reciprocating link 224. Therefore, the gripping mechanism driving actuator 216 continues to operate. After that, when the drive switching pin 222 pushes the second switching lever 244 of the directional control valve 218 with a switching lever, the flow of air inside the directional control valve 218 with a switching lever changes. This causes the gripping mechanism drive actuator 216 to pull the reciprocating link 224. As a result, air is supplied to the gripping mechanism driving actuator 216 via the other air passage 314 between the reciprocating mechanism directional control valve 212 and the gripping mechanism driving actuator 216.
　この空気の供給に伴い、分岐通路３１６、および、往復機構２４とカット機構３０とを連携させるための空気通路３４０にも、空気が供給される。その空気の供給があると、カット機構用方向制御弁２８０は、カット機構駆動用アクチュエータ２８２に対する空気の流れを変える。空気の流れが変わると、カット機構用方向制御弁２８０とカット機構駆動用アクチュエータ２８２のシリンダのピストン貫通部付近との間の空気通路３３２において、カット機構用方向制御弁２８０からカット機構駆動用アクチュエータ２８２へ空気が流れる。カット機構用方向制御弁２８０とカット機構駆動用アクチュエータ２８２のシリンダ底部付近との間の空気通路３３４において、カット機構駆動用アクチュエータ２８２からカット機構用方向制御弁２８０へ空気が流れる。その空気はカット機構用方向制御弁２８０を経由して大気中へ排出される。これにより、カット機構駆動用アクチュエータ２８２のピストンはシリンダ内に収容される。 Along with this air supply, air is also supplied to the branch passage 316 and the air passage 340 for coordinating the reciprocating mechanism 24 and the cutting mechanism 30. When the air is supplied, the cutting mechanism directional control valve 280 changes the flow of air to the cutting mechanism driving actuator 282. When the air flow changes, in the air passage 332 between the cut mechanism directional control valve 280 and the vicinity of the piston penetration part of the cylinder of the cut mechanism drive actuator 282, the cut mechanism drive actuator is moved from the cut mechanism directional control valve 280 to the cut mechanism drive actuator. Air flows to 282. In the air passage 334 between the cutting mechanism directional control valve 280 and the vicinity of the cylinder bottom of the cutting mechanism driving actuator 282, air flows from the cutting mechanism driving actuator 282 to the cutting mechanism directional control valve 280. The air is discharged into the atmosphere via the cut mechanism directional control valve 280. As a result, the piston of the cutting mechanism driving actuator 282 is housed in the cylinder.
　その後、駆動切替ピン２２２がスイッチングレバー付方向制御弁２１８の第１スイッチングレバー２４２を押す。これにより、往復機構用方向制御弁２１２とスイッチングレバー付方向制御弁２１８との間の起動用方向制御弁２２０を経由しない空気通路３２４での空気の供給は遮断される。その際、起動用方向制御弁２２０が閉じている。そのため、往復機構用方向制御弁２１２とスイッチングレバー付方向制御弁２１８との間の起動用方向制御弁２２０を経由する空気通路３２２での空気の供給は停止したままである。その結果、新たな別のバンド５００の引締が可能になる。 Thereafter, the drive switching pin 222 pushes the first switching lever 242 of the directional control valve 218 with a switching lever. As a result, the supply of air through the air passage 324 between the reciprocating mechanism directional control valve 212 and the switching lever-equipped directional control valve 218 without passing through the activation directional control valve 220 is cut off. At this time, the activation directional control valve 220 is closed. Therefore, the supply of air through the air passage 322 via the activation directional control valve 220 between the reciprocating mechanism directional control valve 212 and the switching lever equipped directional control valve 218 remains stopped. As a result, another new band 500 can be tightened.
［本実施形態にかかるバンド引締装置の効果］
　本実施形態にかかるバンド引締装置１０は、傾斜対向面１７０に接触したバンド５００を引っ張る。これにより、例えばバンド支持部１１２にスロットを設けてそのスロットにバンド５００を嵌めてそのバンド５００を引っ張る場合と異なり、そのスロットに嵌まるバンド５００しか引っ張れないといった制約が減少する。その制約が減少するので、引締対象となるバンド５００の範囲を拡大させ得る。 [Effects of the band tightening device according to this embodiment]
The band tightening device 10 according to this embodiment pulls the band 500 that is in contact with the inclined opposing surface 170. This reduces the restriction that only the band 500 that fits into the slot can be pulled, unlike the case where, for example, a slot is provided in the band support part 112 and the band 500 is fitted into the slot and the band 500 is pulled. Since the restriction is reduced, the range of the band 500 to be tightened can be expanded.
　また、本実施形態にかかるバンド引締装置１０は、進入路１２２の内部でのバンド５００の屈曲を抑制できる。 Furthermore, the band tightening device 10 according to the present embodiment can suppress bending of the band 500 inside the approach path 122.
　また、本実施形態にかかるバンド引締装置１０は、バンド５００を引っ張る力を向上させ得る。 Furthermore, the band tightening device 10 according to the present embodiment can improve the force with which the band 500 is pulled.
［変形例の説明］
　今回開示された実施形態はすべての点で例示である。本発明の範囲は上述した実施形態に基づいて制限されるものではない。もちろん、本発明の趣旨を逸脱しない範囲で種々の設計変更をしてもよい。 [Description of modification]
The embodiment disclosed herein is an example in all respects. The scope of the present invention is not limited based on the embodiments described above. Of course, various design changes may be made without departing from the spirit of the invention.
　例えば、支持体９８の形態は特に限定されない。したがって、支持体９８のうちバンド５００に直接接触してこれを支える箇所は平面でなくてもよい。支持体９８がバンド支持面１９０を有している場合、そのバンド支持面１９０が延びる方向は特に限定されない。 For example, the form of the support body 98 is not particularly limited. Therefore, the portion of the support body 98 that directly contacts and supports the band 500 does not have to be flat. When the support body 98 has a band support surface 190, the direction in which the band support surface 190 extends is not particularly limited.
　また、保持アーム３２は、第２ハウジングカバー５４に代えて第１ハウジングカバー５２に固定されてもよい。 Furthermore, the holding arm 32 may be fixed to the first housing cover 52 instead of the second housing cover 54.
