　ファスナーストリンガ連続製造機は高速で稼動し、務歯用金属線材の送り装置は務歯用金属線材を高速で送り、ファスナーテープの供給装置はファスナーストリンガを高速で送り出すので、カムを取り付けた主軸は高速回転する。例えば、１分間に数千回転する。
　このために、ファスナーストリンガ連続製造機を、点検や異常発生時等に稼動を中止するために、停止操作してモータを止め、主軸の回転を停止する際に、主軸は直ちには停止せずに惰性で所定の時間だけ回転し続けた後に停止する。 The fastener stringer continuous manufacturing machine operates at high speed, the metal wire feeding device for dental teeth feeds the metal wire for dental teeth at high speed, and the fastener tape feeder feeds the fastener stringer at high speed. It rotates at high speed. For example, several thousand revolutions per minute.
For this reason, in order to stop the operation of the fastener stringer continuous manufacturing machine at the time of inspection or when an abnormality occurs, when stopping the motor by stopping operation, the spindle does not stop immediately. It stops by inertia after continuing to rotate for a predetermined time.
　このように、停止操作後に主軸が回転し続けるので、停止操作後に務歯用金属線材が送り装置によりある程度の長さだけ送られ、停止操作後にファスナーテープが供給装置によりある程度の長さだけ送られるので、ファスナーテープに務歯を取り付けたファスナーストリンガが停止操作後にある程度の長さだけ作製される。
　しかしながら、停止操作後の務歯用金属線材、ファスナーテープの送りはファスナーストリンガ連続製造機の稼動時の送りとは異なるので、停止操作後に作製されたファスナーストリンガは不良品であるから、務歯用金属線材、ファスナーテープが無駄に消費され、コストアップの原因となる。 As described above, since the main shaft continues to rotate after the stop operation, the dental metal wire is fed by a certain length by the feeder after the stop operation, and the fastener tape is fed by a certain length by the feeder after the stop operation. Therefore, the fastener stringer with the fasteners attached to the fastener tape is produced to a certain length after the stop operation.
However, since the feed of the metal wire for fasteners and fastener tape after the stop operation is different from the feed at the time of operation of the fastener stringer continuous manufacturing machine, the fastener stringer produced after the stop operation is a defective product. Metal wires and fastener tapes are wasted, leading to increased costs.
　本発明は、前述の課題を解決するためになされたものであり、その目的は、ファスナーストリンガ連続製造機を停止操作することで務歯用金属線材、ファスナーテープの送りを直ちに停止できるようにしたファスナーストリンガ連続製造機とすることである。 The present invention has been made in order to solve the above-described problems, and its purpose is to immediately stop the feeding of the metal wire for fasteners and the fastener tape by stopping the fastener stringer continuous manufacturing machine. The fastener stringer continuous manufacturing machine.

　このようにすれば、主軸３０とともに線材供給用カム３３を高速回転して線材送りローラ１１を間欠的に高速で回転できると共に、ファスナーストリンガ連続製造機を停止操作したときには主軸３０が回転していても線材送りローラ１１の回転を停止して務歯用金属線材の送りを直ちに停止できる。 In this way, the wire rod feed cam 11 can be intermittently rotated at a high speed by rotating the wire rod supply cam 33 together with the main shaft 30, and the main shaft 30 is rotating when the fastener stringer continuous manufacturing machine is stopped. In addition, the rotation of the wire rod feed roller 11 can be stopped to immediately stop the feeding of the metal wire for the tooth.

　この務歯の成形植付け部１は、従来と同様であるので、全体を仮想線で囲って図示し、各部材の図示を省略してある。 The service tooth molding planting portion 1 has a cutting die and a cutting punch that are formed into a substantially Y-shaped service tooth material having a head and a pair of legs by cutting the metal wire W for service teeth into a predetermined thickness. A cutting die, a forming die having a head and a forming punch having a pocket and a crest, a forming device having a forming punch, and a pair of legs of the tooth E A dentition attachment device having a pair of caulking punches that are swaged to the dentition attachment portion of the fastener tape T and a pair of chamfering punches that chamfer a pair of leg portions of the dentition E attached to the fastener tape T It has.
Since the molded tooth implant 1 is similar to the conventional one, the whole is surrounded by an imaginary line, and the illustration of each member is omitted.
　前記務歯用金属線材の送り装置１０は、前記回転軸３０の回転により間欠的に回転する線材送りローラ１１とガイドローラ１２を有する。この線材送りローラ１１とガイドローラ１２で務歯用金属線材Ｗをはさむようにして務歯用金属線材Ｗを前述した務歯の成形植付け部１に向けて間欠的に送る。
　前記線材送りローラ１１を回転する伝達軸１３にラチエットホイール１４が固着してある。
　このラチエットホイール１４に係合、離脱するラチエット爪１５が前記主軸３０の線材送り用カム３３に線材送り用カム従節機構１６で接続し、主軸３０とともに線材送り用カム３３が回転することでラチエット爪１５が往復移動するようにしてある。
　そして、ラチエット爪１５が矢印ａで示すようにラチエットホイール１４に接近する方向に移動、つまり往移動することでラチエットホイール１４が所定の回転角度だけ回転し、ラチエット爪１５が矢印ｂで示すようにラチエットホイール１４と離れる方向に移動、つまり復移動する際にはラチエットホイール１４が回転しない。
　これによって伝達軸１３が間欠的に回転し、線材送りローラ１１が間欠的に回転する。 The metal tooth wire feeding device 10 for a tooth has a wire feeding roller 11 and a guide roller 12 that rotate intermittently by the rotation of the rotating shaft 30. The dental metal wire W is intermittently fed toward the above-described fixed tooth molding planting portion 1 by sandwiching the dental metal wire W between the wire feeding roller 11 and the guide roller 12.
A ratchet wheel 14 is fixed to a transmission shaft 13 that rotates the wire feed roller 11.
The ratchet pawl 15 that engages and disengages from the ratchet wheel 14 is connected to the wire rod feed cam 33 of the main shaft 30 by the wire rod feed cam follower mechanism 16, and the wire rod feed cam 33 rotates together with the main shaft 30, thereby causing the ratchet. The claw 15 is configured to reciprocate.
Then, the ratchet pawl 15 moves in a direction approaching the ratchet wheel 14 as indicated by an arrow a, that is, moves forward, so that the ratchet wheel 14 rotates by a predetermined rotation angle, and the ratchet pawl 15 as indicated by an arrow b. When moving away from the ratchet wheel 14, that is, when moving backward, the ratchet wheel 14 does not rotate.
As a result, the transmission shaft 13 rotates intermittently, and the wire feed roller 11 rotates intermittently.
　前記線材送り用カム従節機構１６は、仮想線で示したガイド１７に往復移動自在に設けた移動体１８と、この移動体１８の基端に設けたローラ１９と、この移動体１８を一方向に移動してローラ１９を線材送り用カム３３に押しつけるばね１６ａを有している。
　そして、前記移動体１８の先端にラチエット爪１５を取付け、そのラチエット爪１５の尖端部１５ａがラチエットホイール１４の歯１４ａに係合、離脱するようにしてある。 The wire feed cam follower mechanism 16 includes a moving body 18 provided on a guide 17 indicated by an imaginary line so as to be reciprocally movable, a roller 19 provided at a base end of the moving body 18, and the moving body 18. A spring 16a that moves in the direction and presses the roller 19 against the wire feeding cam 33 is provided.
A ratchet pawl 15 is attached to the tip of the moving body 18, and a pointed portion 15 a of the ratchet pawl 15 is engaged with and disengaged from a tooth 14 a of the ratchet wheel 14.
　前記ファスナーテープの供給装置２０は、前記主軸３０の回転により間欠的に回転するテープ供給ローラ２１と、加圧ローラ２２を有している。
　前記テープ供給ローラ２１と加圧ローラ２２でファスナーストリンガＳを挟持し、そのテープ供給ローラ２１が間欠的に回転することでファスナーストリンガＳを間欠的に送り出すことで、ファスナーテープＴを務歯の成形植付け部１に向けて間欠的に供給する。
　すなわち、テープ供給ローラ２１と加圧ローラ２２は務歯の成形植付け部１よりも送り出し側に設けられ、ファスナーテープＴに務歯Ｅを取付けしたファスナーストリンガＳを送り出すことでファスナーテープＴを成形植付け部１に供給する。 The fastener tape supply device 20 includes a tape supply roller 21 that rotates intermittently by the rotation of the main shaft 30 and a pressure roller 22.
The fastener stringer S is sandwiched between the tape supply roller 21 and the pressure roller 22, and the fastener stringer S is intermittently fed by the tape supply roller 21 rotating intermittently. It supplies intermittently toward the planting part 1.
That is, the tape supply roller 21 and the pressure roller 22 are provided on the delivery side of the service tooth molding planting portion 1, and the fastener stringer S with the service tooth E attached to the fastener tape T is delivered to mold and plant the fastener tape T. Supply to part 1.
　前記テープ供給ローラ２１を回転する伝達軸２３が前記主軸３０のテープ供給用カム３４にテープ供給用カム従節機構２４で接続してある。
　前記テープ供給用カム従節機構２４は、機枠（図示せず）に揺動自在に取付けた第１レバー２４ａと、この第１レバー２４ａの一端に設けた第１ローラ２４ｂと、前記第１レバー２４ａの他端に設けた第２ローラ２４ｃと、前記伝達軸２３に固定した第２レバー２４ｄを有し、前記第２レバー２４ｄをばね２４ｅで一方向に揺動付勢して第２レバー２４ｄを第２ローラ２４ｃに押しつけ、第１ローラ２４ｂをテープ供給用カム３４に押しつける。そして主軸３０とともにテープ供給用カム３４が回転することで第１レバー２４ａが揺動し、第２ローラ２４ｃで第２レバー２４ｄを揺動することによって伝達軸２３を回転してテープ供給ローラ２１を一方向に間欠的に回転する。
　前記務歯の成形植付け部１と対向してテープガイド２５が設けてある。 A transmission shaft 23 that rotates the tape supply roller 21 is connected to a tape supply cam 34 of the main shaft 30 by a tape supply cam follower mechanism 24.
The tape supply cam follower mechanism 24 includes a first lever 24a swingably attached to a machine frame (not shown), a first roller 24b provided at one end of the first lever 24a, and the first lever 24a. A second roller 24c provided at the other end of the lever 24a and a second lever 24d fixed to the transmission shaft 23 are provided. The second lever 24d is oscillated and biased in one direction by a spring 24e. 24d is pressed against the second roller 24c, and the first roller 24b is pressed against the tape supply cam 34. Then, the tape supply cam 34 rotates together with the main shaft 30 to swing the first lever 24a, and the second roller 24c swings the second lever 24d to rotate the transmission shaft 23 to move the tape supply roller 21. Rotates intermittently in one direction.
A tape guide 25 is provided so as to face the molded tooth implant 1.
　線材送り用カム３３及びテープ供給用カム３４を備えた主軸３０は、ファスナーストリンガ連続製造機を稼動しているときには高速回転しているので、ファスナーストリンガ連続製造機の稼動を中止するために停止操作し、モータＭを止め、主軸３０の回転を停止する際に、主軸３０は直ちに停止せずに惰性で所定の時間だけ回転し続け、務歯用金属線材Ｗ及びファスナーテープＴが停止操作後にある程度の長さだけ送られてしまう。 Since the main shaft 30 provided with the wire feeding cam 33 and the tape supply cam 34 rotates at a high speed when the continuous fastener stringer manufacturing machine is in operation, a stop operation is performed to stop the operation of the continuous fastener stringer manufacturing machine. Then, when the motor M is stopped and the rotation of the main shaft 30 is stopped, the main shaft 30 does not stop immediately but continues to rotate for a predetermined time due to inertia, and the dental metal wire W and the fastener tape T are to some extent after the stop operation. Will be sent only the length of.
　本発明のファスナーストリンガ連続製造機は、図１に示すように、主軸３０とともに線材送り用カム３３が回転しているときに、線材送り用カム従節機構１６によりラチエット爪１５が往復移動しないようにすることで、ラチエットホイール１４の回転を抑制し、務歯用金属線材Ｗの送りを抑制する線材送り抑制手段４０を備えている。
　この線材送り抑制手段４０は、ファスナーストリンガ連続製造機の稼動を中止する停止操作による電気信号で抑制作動する。
　例えば、主軸３０を駆動するモータＭを停止する電気信号によりソレノイドを作動し、ラチエットホイール１４の回転を抑制する。 As shown in FIG. 1, the fastener stringer continuous manufacturing machine of the present invention prevents the ratchet pawl 15 from reciprocating by the wire feed cam follower mechanism 16 when the wire feed cam 33 rotates together with the main shaft 30. Thus, wire rod feed restraining means 40 that restrains the rotation of the ratchet wheel 14 and restrains the feed of the metal wire W for the tooth is provided.
The wire feed suppression means 40 is suppressed by an electrical signal generated by a stop operation that stops the operation of the fastener stringer continuous manufacturing machine.
For example, a solenoid is actuated by an electrical signal that stops the motor M that drives the main shaft 30 to suppress the rotation of the ratchet wheel 14.
　本発明のファスナーストリンガ連続製造機は、さらに、主軸３０とともにテープ供給用カム３４が回転しているときに、テープ供給用カム従節機２４によるテープ供給ローラ２１の回転を抑制してファスナーテープＴの送りを抑制するテープ送り抑制手段５０を備えている。
　このテープ送り抑制手段５０は、ファスナーストリンガ連続製造機の稼動を中止する停止操作による電気信号で抑制作動する。
　例えば、主軸３０を駆動するモータＭを停止する電気信号によりソレノイドを作動し、テープ供給ローラ２１の回転を抑制する。 The continuous fastener stringer manufacturing machine of the present invention further suppresses the rotation of the tape supply roller 21 by the tape supply cam follower 24 when the tape supply cam 34 is rotating together with the main shaft 30, and the fastener tape T Is provided with a tape feed restraining means 50 for restraining the feed.
The tape feed suppressing means 50 is suppressed by an electrical signal generated by a stop operation for stopping the operation of the fastener stringer continuous manufacturing machine.
For example, a solenoid is actuated by an electrical signal that stops the motor M that drives the main shaft 30, and the rotation of the tape supply roller 21 is suppressed.
　このようにすることで、本発明のファスナーストリンガ連続製造機は、停止操作すると直ちに線材送り抑制手段４０で線材送りローラ１１の回転を抑制し、テープ送り抑制手段５０でテープ供給ローラ２１の回転を抑制するので、務歯用金属線材Ｗ及びファスナーテープＴの送りを、ファスナーストリンガ連続製造機の停止操作した直後に停止することができる。 By doing in this way, the fastener stringer continuous manufacturing machine of the present invention immediately suppresses the rotation of the wire feed roller 11 by the wire feed suppression means 40 and stops the rotation of the tape supply roller 21 by the tape feed suppression means 50 when the stop operation is performed. Since it suppresses, feeding of the metal wire W for fasteners and the fastener tape T can be stopped immediately after stopping operation of the fastener stringer continuous manufacturing machine.
　次に、線材送り抑制手段４０を説明する。
　図１に示すように、主軸３０とともに線材送り用カム３３が回転し、そのカム３３のカム面における大径部がローラ１９に接することで待機位置の移動体１８がばね１６ａに抗して矢印ａで示すようにラチエットホイール１４に接近する方向にラチエット爪１５とともに移動、つまり往移動し、ストロークエンド位置まで往移動することで、ラチエット爪１５でラチエットホイール１４が所定の回転角度回転する。
　線材送り用カム３３のカム面における小径部がローラ１９に接することで移動体１８がばね１６ａで矢印ｂで示すようにラチエットホイール１４と離れる方向にラチエット爪１５とともに移動、つまり復移動して移動体１８がラチエット爪１５とともに待機位置に復帰する。 Next, the wire rod feed suppressing means 40 will be described.
As shown in FIG. 1, the wire rod feeding cam 33 rotates together with the main shaft 30, and the large diameter portion of the cam surface of the cam 33 comes into contact with the roller 19, so that the moving body 18 at the standby position opposes the spring 16a. As shown by a, the ratchet wheel 14 is moved together with the ratchet pawl 15 in a direction approaching the ratchet wheel 14, that is, moved forward, and moved forward to the stroke end position, whereby the ratchet wheel 14 is rotated by a predetermined rotation angle.
When the small diameter portion of the cam surface of the wire feeding cam 33 comes into contact with the roller 19, the moving body 18 moves with the ratchet pawl 15 in the direction away from the ratchet wheel 14 as shown by the arrow b by the spring 16a, that is, moves backward and moves. The body 18 returns to the standby position together with the ratchet pawl 15.
　線材送り抑制手段４０は、ストロークエンド位置まで往移動した移動体１８を、前述したように線材送り用カム３３のカム面の小径部がローラ１９に対向したときにばね１６ａで待機位置に向けて復移動しないようにストロークエンド位置で保持することで、その後に主軸３０が惰性で回転し、主軸３０とともに線材送り用カム３３が回転してもラチエットホイール１４が回転せずに、務歯用金属線材Ｗの送りを抑制する。 The wire feed suppression means 40 moves the moving body 18 moved forward to the stroke end position toward the standby position by the spring 16a when the small diameter portion of the cam surface of the wire feed cam 33 faces the roller 19 as described above. By holding at the stroke end position so as not to move backward, the main shaft 30 rotates by inertia, and even if the wire feeding cam 33 rotates together with the main shaft 30, the ratchet wheel 14 does not rotate, but the metal for dental dentition The feeding of the wire W is suppressed.
　線材送り抑制手段４０は、図２に示すように、図示しない機枠に取り付けたブラケット４１に設けたロータリソレノイド４２と、このロータリソレノイド４２で移動するストッパ４３と、移動体１８に設けたストッパ受け４４を備えている。
　ロータリソレノイド４２の回転部４２ａにレバー４５を固定し、レバー４５にロッド４６の一端部を回動自在に連結する。
　ロッド４６の他端部に移動片４７を回動自在に設け、この移動片４７にストッパ４３をストッパ受け４４に向けて移動自在に設けると共に、スプリング４８でストッパ受け４４に向けて移動付勢する。 As shown in FIG. 2, the wire rod feed suppressing means 40 includes a rotary solenoid 42 provided on a bracket 41 attached to a machine frame (not shown), a stopper 43 moved by the rotary solenoid 42, and a stopper receiver provided on the moving body 18. 44.
A lever 45 is fixed to the rotating portion 42a of the rotary solenoid 42, and one end of a rod 46 is rotatably connected to the lever 45.
A movable piece 47 is rotatably provided at the other end of the rod 46, and a stopper 43 is movably provided on the movable piece 47 toward the stopper receiver 44, and the spring 48 is urged to move toward the stopper receiver 44. .
　ロータリソレノイド４２は、ファスナーストリンガ連続製造機が稼動しているときには通電されないが、稼動しているファスナーストリンガ連続製造機を停止する停止操作をしたときに制御部１００により通電される。
　ロータリソレノイド４２に通電されないときには、図２に示すようにストッパ４３の先端面４３ａがストッパ受け４４の移動体１８の移動方向に沿った表面４４ａと隙間を有して対峙する。 The rotary solenoid 42 is not energized when the continuous fastener stringer manufacturing machine is operating, but is energized by the control unit 100 when a stop operation is performed to stop the continuous fastener stringer manufacturing machine.
When the rotary solenoid 42 is not energized, the tip surface 43a of the stopper 43 faces the surface 44a of the stopper receiver 44 along the moving direction of the moving body 18 with a gap as shown in FIG.
　ロータリソレノイド４２に通電すると、図３に示すように、ロータリソレノイド４２の回転部４２ａが回転してレバー４５、ロッド４６を介して移動片４７が移動し、スプリング４８を介してストッパ４３がストッパ受け４４に向けて移動し、ストッパ４３の先端面４３ａがストッパ受け４４の移動体１８の移動方向に向かう表面４４ａに接するようにしてある。 When the rotary solenoid 42 is energized, as shown in FIG. 3, the rotating portion 42 a of the rotary solenoid 42 rotates to move the moving piece 47 via the lever 45 and the rod 46, and the stopper 43 receives the stopper receiving via the spring 48. 44, the tip end surface 43a of the stopper 43 is in contact with the surface 44a of the stopper receiver 44 in the moving direction of the moving body 18.
　そして、図４に示すように、移動体１８がラチエット爪１５とともにストロークエンド位置まで往移動すると、ストッパ４３がスプリング４８でストッパ受け４４のストッパ受け部、例えばストッパ受け４４における移動体１８の復移動方向の端面４４ｂに接し、移動体１８をストロークエンド位置で保持し、移動体１８がばね１６ａで待機位置に向けて復移動しないようにする。
　つまり、移動体１８が往移動するときに、ストッパ受け４４の表面４４ａがストッパ４３の先端面４３ａに沿って移動し、移動体１８がストロークエンド位置まで往移動するとストッパ４３がスプリング４８でストッパ受け４４に向けて移動し、ストッパ受け４４の表面４４ａから外れて端面４４ｂに接する。 As shown in FIG. 4, when the moving body 18 moves forward to the stroke end position together with the ratchet pawl 15, the stopper 43 is moved by the spring 48 to the stopper receiving portion of the stopper receiver 44, for example, the backward movement of the moving body 18 in the stopper receiver 44. The moving body 18 is held at the stroke end position so that the moving body 18 does not move backward toward the standby position by the spring 16a.
That is, when the moving body 18 moves forward, the surface 44 a of the stopper receiver 44 moves along the tip end surface 43 a of the stopper 43, and when the moving body 18 moves forward to the stroke end position, the stopper 43 is stopped by the spring 48. 44, moves away from the surface 44a of the stopper receiver 44 and contacts the end face 44b.
　このようにすることで、移動体１８が待機位置のとき、移動体１８がストロークエンド位置まで往移動したとき、移動体１８がこの位置と待機位置との間の任意の位置のとき、つまり移動体１８の位置に関係なくロータリソレノイド４２に通電することで、ストロークエンド位置まで往移動した移動体１８を待機位置に向けて復移動しないように保持することができる。 In this way, when the moving body 18 is at the standby position, when the moving body 18 moves forward to the stroke end position, when the moving body 18 is at an arbitrary position between this position and the standby position, that is, the movement By energizing the rotary solenoid 42 regardless of the position of the body 18, the moving body 18 that has moved forward to the stroke end position can be held so as not to move backward toward the standby position.
　次に、ファスナーテープの供給装置２０のテープ送り動作を説明する。
　図１に示すように、第２レバー２４ｄは、ばね２４ｅで矢印ｃで示す上方に揺動し、図５に示すように第２ローラ２４ｃを介して第１レバー２４ａを矢印ｄで示す方向に揺動して第１レバー２４ａを待機姿勢とする。このとき、第１ローラ２４ｂはテープ供給用カム３４のカム面の小径部３４ａに接する。
　第１レバー２４ａが待機姿勢の状態で、主軸３０とともにテープ供給用カム３４が回転し、図６に示すように、そのカム３４のカム面の大径部３４ｂが第１ローラ２４ｂに接すると、第１レバー２４ａが矢印ｄと反対方向の矢印ｅ方向に揺動して送り姿勢となり、第２ローラ２４ｃで第２レバー２４ｄを矢印ｃと反対方向である矢印ｆ方向に揺動することで、伝達軸２３が矢印ｇ方向に回転し、テープ供給ローラ２１が矢印ｈ方向に所定の回転角度回転し、ファスナーストリンガＳを送り出すことで、ファスナーテープＴを務歯の成形植付け部１に向けて送る。 Next, the tape feeding operation of the fastener tape supply device 20 will be described.
As shown in FIG. 1, the second lever 24d swings upward as indicated by the arrow c by the spring 24e, and as shown in FIG. 5, the first lever 24a is moved in the direction indicated by the arrow d via the second roller 24c. The first lever 24a is set in a standby posture by swinging. At this time, the first roller 24 b contacts the small diameter portion 34 a of the cam surface of the tape supply cam 34.
When the first lever 24a is in the standby posture, the tape supply cam 34 rotates together with the main shaft 30, and when the large diameter portion 34b of the cam surface of the cam 34 comes into contact with the first roller 24b, as shown in FIG. The first lever 24a swings in the direction of arrow e opposite to the arrow d to become a feeding posture, and the second roller 24c swings in the direction of arrow f opposite to the arrow c by the second roller 24c. The transmission shaft 23 rotates in the direction of the arrow g, the tape supply roller 21 rotates in the direction of the arrow h by a predetermined rotation angle, and the fastener stringer S is sent out, so that the fastener tape T is sent toward the molded tooth implanting portion 1. .
　主軸３０とともにテープ供給用カム３４がさらに回転し、図５に示すようにそのカム３４のカム面の小径部３４ａが第１ローラ２４ｂと対向すると、ばね２４ｅで第２レバー２４ｄが矢印ｃ方向に揺動し、第１レバー２４ａが矢印ｄ方向に揺動して待機姿勢に復帰する。 When the tape supply cam 34 further rotates together with the main shaft 30, and the small diameter portion 34a of the cam surface of the cam 34 faces the first roller 24b as shown in FIG. 5, the second lever 24d is moved in the direction of arrow c by the spring 24e. The first lever 24a swings in the direction of the arrow d and returns to the standby posture.
このとき、伝達軸２３は矢印ｇと反対方向である矢印ｉ方向に回転するが、テープ供給ローラ２１は回転せずに停止している。
　つまり、伝達軸２３とテープ供給ローラ２１とは、伝達軸２３が矢印ｇ方向に回転するときにはテープ供給ローラ２１は矢印ｈ方向に回転するが、伝達軸２３が矢印ｇと反対方向である矢印ｉ方向に回転するときはテープ供給ローラ２１は回転しないようにしてある。
　例えば、伝達軸２３とテープ供給ローラ２１をラチエット爪とラチエットホイールを用いて接続し、その伝達軸２３の一方向の回転（矢印ｇ方向の回転）によってテープ供給ローラ２１を供給方向（矢印ｈ方向）に所定の回転角度だけ回転し、伝達軸２３が他方向に回転（矢印ｇと反対方向の矢印ｉ方向の回転）したときにはテープ供給ローラ２１を回転せずに停止するようにしてある。 At this time, the transmission shaft 23 rotates in the direction of arrow i, which is the opposite direction to the arrow g, but the tape supply roller 21 stops without rotating.
That is, the transmission shaft 23 and the tape supply roller 21 are configured such that when the transmission shaft 23 rotates in the direction of the arrow g, the tape supply roller 21 rotates in the direction of the arrow h, but the transmission shaft 23 is in the direction opposite to the arrow g. When rotating in the direction, the tape supply roller 21 does not rotate.
For example, the transmission shaft 23 and the tape supply roller 21 are connected using a ratchet pawl and a ratchet wheel, and the tape supply roller 21 is supplied in the supply direction (arrow h direction) by rotating the transmission shaft 23 in one direction (rotation in the arrow g direction). When the transmission shaft 23 rotates in the other direction (rotation in the direction of arrow i opposite to the arrow g), the tape supply roller 21 is stopped without rotating.
　このようであるから、ファスナーテープの供給装置２０は務歯の成形植付け部１の下流側に設けられ、ファスナーストリンガＳを、間欠的に所定の送り量送り出すことでファスナーテープＴを務歯の成形植付け部１に向けて所定の供給量ごとに間欠的に供給する。 Therefore, the fastener tape supply device 20 is provided on the downstream side of the fixed tooth molding planting portion 1, and the fastener stringer S is intermittently fed a predetermined feed amount to form the fastener tape T. It supplies intermittently toward the planting part 1 for every predetermined supply amount.
　テープ送り抑制手段５０は、送り姿勢に揺動した第１レバー２４ａを、前述のようにテープ供給用カム３４のカム面の小径部３４ａが第１ローラ２４ｂと対向したときに、待機姿勢に揺動しないように送り姿勢で保持することで、主軸３０とともにテープ供給用カム３４が回転しても第１レバー２４ａが揺動せずにファスナーテープＴの送りを抑制する。 The tape feed suppressing means 50 swings the first lever 24a swinging to the feed posture to the standby posture when the small diameter portion 34a of the cam surface of the tape supply cam 34 faces the first roller 24b as described above. By holding the feeding posture so as not to move, even if the tape supply cam 34 rotates together with the main shaft 30, the first lever 24a does not swing and the feeding of the fastener tape T is suppressed.
　テープ送り抑制手段５０は図５に示すように、第１レバー２４ａに設けたストッパ受け５１と、このストッパ受け５１と対峙して設けたストッパ５２と、図示しない機枠に固定したブラケット５３に取り付けたロータリソレノイド５４を備えている。
　ロータリソレノイド５４の回転部５４ａにレバー５５を固定し、このレバー５５に回動自在に連結したロット５６をストッパ５２に回動自在に連結することで、ロータリソレノイド５０に通電して回転部５０ａを所定の回転角度回転すると、レバー５５、ロッド５６を介してストッパ５２がストッパ受け５１に向けて移動するようにしてある。 As shown in FIG. 5, the tape feed suppressing means 50 is attached to a stopper receiver 51 provided on the first lever 24a, a stopper 52 provided opposite to the stopper receiver 51, and a bracket 53 fixed to a machine frame (not shown). A rotary solenoid 54 is provided.
A lever 55 is fixed to the rotating portion 54a of the rotary solenoid 54, and a lot 56 that is rotatably connected to the lever 55 is rotatably connected to the stopper 52, whereby the rotary solenoid 50 is energized and the rotating portion 50a is turned on. When rotated by a predetermined rotation angle, the stopper 52 moves toward the stopper receiver 51 via the lever 55 and the rod 56.
　ロータリソレノイド５４に通電しない状態で、第１レバー２４ａが待機姿勢のときには、図５に示すようにストッパ５２の先端面５２ａがストッパ受け５１の表面５１ａと間隔を置いて対峙し、ロータリソレノイド５４に通電したときには図７に示すようにストッパ５２の先端面５２ａがストッパ受け５１の表面５１ａに接する。 When the first lever 24a is in the standby position with the rotary solenoid 54 not energized, the front end surface 52a of the stopper 52 faces the surface 51a of the stopper receiver 51 with a space therebetween as shown in FIG. When energized, the tip surface 52a of the stopper 52 contacts the surface 51a of the stopper receiver 51 as shown in FIG.
　ロータリソレノイド５４に通電しない状態で、第１レバー２４ａが送り姿勢のときには、図６に示すように、ストッパ５２の先端面５２ａがストッパ受け５１のストッパ受け部、例えば切欠部５１ｂと間隔を置いて対峙し、ロータリソレノイド５４に通電したときには図８に示すように、ストッパ５２がストッパ受け５１の切欠部５１ｂに係合する。
　ストッパ５２がストッパ受け５１の切欠部５１ｂに係合すると、第１レバー２４ａがばね３４ｅのばね力で矢印ｄ方向に揺動できなくなり、第１レバー２４ａを送り姿勢で保持する。 When the first lever 24a is in the feeding posture without energizing the rotary solenoid 54, as shown in FIG. In contrast, when the rotary solenoid 54 is energized, the stopper 52 engages with the notch 51b of the stopper receiver 51 as shown in FIG.
When the stopper 52 is engaged with the notch 51b of the stopper receiver 51, the first lever 24a cannot be swung in the direction of the arrow d by the spring force of the spring 34e, and the first lever 24a is held in the feeding posture.
　ロータリソレノイド５４はファスナーストリンガ連続製造機が稼動しているときには通電されないが、稼動しているファスナーストリンガ連続製造機を停止する停止操作したときに制御部１００により通電される。 The rotary solenoid 54 is not energized when the continuous fastener stringer machine is in operation, but is energized by the control unit 100 when a stop operation is performed to stop the continuous fastener stringer machine.
　このようであるから、ファスナーストリンガ連続製造機を停止操作すると、ロータリソレノイド５４に通電されてストッパ５２がストッパ受け５１の切欠部５１ｂに係合して第１レバー２４ａを送り姿勢に保持し、その後に主軸３０が回転して図８に仮想線で示すように、テープ供給用カム３４のカム面の小径部３４ａが第１ローラ２４ｂと対向しても第１レバー２４ａがばね２４ｅで待機位置に揺動しないので、ファスナーストリンガ連続製造機を停止操作するとファスナーテープＴの送りが直ちに停止する。 Therefore, when the continuous operation of the fastener stringer is stopped, the rotary solenoid 54 is energized, the stopper 52 engages with the notch 51b of the stopper receiver 51, and the first lever 24a is held in the feeding posture. When the main shaft 30 rotates and the small diameter portion 34a of the cam surface of the tape supply cam 34 faces the first roller 24b as shown by the phantom line in FIG. 8, the first lever 24a is moved to the standby position by the spring 24e. Since it does not swing, when the fastener stringer continuous manufacturing machine is stopped, the feeding of the fastener tape T is immediately stopped.
　第１レバー２４が図５に示す待機姿勢のときにロータリソレノイド５４に通電されると、図７に示すようにストッパ５２の先端面５２ａがストッパ受け５１の表面５１ａに接する。
　この状態で主軸３０とともにテープ送り用カム３４が回転し、第１ローラ２４ｂに接するカム３４のカム面が小径部３４ａから大径部３４ｂに変わることで、第１レバー２４ａが送り姿勢に揺動するときには、ストッパ受け５１の表面５１ａがストッパ５２の先端面５２ａに沿って移動し、第１レバー２４ａが送り姿勢となるとストッパ５２がストッパ受け５１の切欠部５１ｂに係合する。
　このようにするには、ストッパ５２を基部と先部に２分割し、基部と先部をばねを介して連結し、ストッパ５２の先端面５２ａがストッパ受け５１の表面５１ａに接したときには、ばねがたわみ、ストッパ５２が切欠部５１ｂと対向したときにはばねの力でストッパ５２の先部が移動して切欠部５１ｂに係合する。 When the rotary solenoid 54 is energized when the first lever 24 is in the standby posture shown in FIG. 5, the tip end surface 52 a of the stopper 52 contacts the surface 51 a of the stopper receiver 51 as shown in FIG. 7.
In this state, the tape feeding cam 34 rotates together with the main shaft 30, and the cam surface of the cam 34 that contacts the first roller 24b changes from the small diameter portion 34a to the large diameter portion 34b, so that the first lever 24a swings to the feeding posture. When the first lever 24a is in the feeding posture, the stopper 52 is engaged with the notch 51b of the stopper receiver 51. The surface 51a of the stopper receiver 51 moves along the tip surface 52a of the stopper 52.
To do this, the stopper 52 is divided into two parts, a base part and a front part, the base part and the front part are connected via a spring, and when the tip end surface 52a of the stopper 52 contacts the surface 51a of the stopper receiver 51, the spring When the stopper 52 is opposed to the notch 51b, the tip of the stopper 52 is moved by the spring force to engage with the notch 51b.
　このようであるから、第１レバー２４ａが待機姿勢、送り姿勢のどちらでも、あるいは待機姿勢と送り姿勢の中間の姿勢でロータリソレノイド５４に通電した場合に、第１レバー２４ａを送り姿勢で保持することができる。 As such, when the first lever 24a is energized to the rotary solenoid 54 in either the standby posture or the feed posture, or in an intermediate position between the standby posture and the feed posture, the first lever 24a is held in the feed posture. be able to.
　前述の実施の形態では、第１レバー２４ａの第２ローラ２４ｃ寄りにストッパ受け５１を設けたが、これに限ることはない。
　例えば、図９に示すように第１レバー２４ａの第１ローラ２４ｂ寄りにストッパ受け５１を設け、そのストッパ受け５１のストッパ受け部を穴５１ｃとし、図１０に示すように、第１レバー２４ａが送り姿勢で、ロータリソレノイド５４に通電したときにストッパ５２がストッパ受け５１の穴５１ｃに嵌まり合うように係合するようにしても良い。 In the above-described embodiment, the stopper receiver 51 is provided near the second roller 24c of the first lever 24a. However, the present invention is not limited to this.
For example, as shown in FIG. 9, a stopper receiver 51 is provided near the first roller 24b of the first lever 24a, and the stopper receiver 51 of the stopper receiver 51 is formed as a hole 51c. As shown in FIG. In the feed posture, when the rotary solenoid 54 is energized, the stopper 52 may be engaged with the hole 51 c of the stopper receiver 51.
　前述の実施の形態では、ロータリソレノイド４２，５４でストッパ４３，５２を移動したが、直線的に作動する直動式のソレノイドを用いることができる。 In the above-described embodiment, the stoppers 43 and 52 are moved by the rotary solenoids 42 and 54, but a linear motion solenoid that operates linearly can be used.
