Description

フィーダ装置Feeder device
　本発明は、フィーダ装置に関する。 The present invention relates to a feeder device.
　従来、電子部品などの部品を基板に装着するために部品を部品装着機に向けて順次供給するためのフィーダ装置が知られている（例えば、特許文献１及び２参照）。フィーダ装置は、複数の部品が収容されたキャリアテープが巻回されたリールを回転可能に支持している。フィーダ装置は、リールに巻回されたキャリアテープを挿入するためのテープ挿入部と、部品が取り出されたキャリアテープを外部に排出するためのテープ排出部と、それらのテープ挿入部とテープ排出部とを繋ぐテープ搬送路と、を有している。リールに巻回されたキャリアテープは、テープ挿入部に挿入され、テープ搬送路に沿って搬送されると共に、部品吸着位置での部品の取り出し後にテープ排出部から外部に排出される。 2. Description of the Related Art Conventionally, a feeder device for sequentially supplying components to a component mounting machine in order to mount components such as electronic components on a substrate is known (see, for example, Patent Documents 1 and 2). The feeder device rotatably supports a reel on which a carrier tape containing a plurality of components is wound. The feeder device includes a tape insertion portion for inserting a carrier tape wound around a reel, a tape discharge portion for discharging the carrier tape from which components are taken out, and the tape insertion portion and the tape discharge portion. And a tape conveyance path connecting the two. The carrier tape wound around the reel is inserted into the tape insertion portion, conveyed along the tape conveyance path, and discharged from the tape discharge portion to the outside after taking out the component at the component suction position.
　フィーダ装置は、キャリアテープを搬送するためのスプロケットと、そのスプロケットを回転駆動するモータと、を備えている。スプロケットは、キャリアテープに設けられた係合穴に係合可能な突起を有している。スプロケットは、特にオートローディング方式のフィーダ装置では、フィーダ本体の前部と後部とに一つずつ設けられる。前部側スプロケットは、正回転により、テープ挿入部に挿入されたキャリアテープを前進させてテープ搬送路に沿ってテープ排出部側へ向けて送出する。また、後部側スプロケットは、正回転により、テープ搬送路に沿って搬送されたキャリアテープを前進させてテープ排出部から外部へ送出する。 The feeder device includes a sprocket for transporting the carrier tape and a motor for rotationally driving the sprocket. The sprocket has a protrusion that can be engaged with an engagement hole provided in the carrier tape. One sprocket is provided at each of a front portion and a rear portion of the feeder main body, particularly in an auto loading type feeder apparatus. The front-side sprocket advances the carrier tape inserted in the tape insertion portion by forward rotation and sends it toward the tape discharge portion along the tape transport path. The rear sprocket forwards the carrier tape transported along the tape transport path and forwards it from the tape discharge section to the outside by forward rotation.

　ところで、フィーダ装置にセットされたキャリアテープを不使用などに伴う交換時などにそのフィーダ装置から取り出すうえでは、スプロケットを正回転させることでそのキャリアテープを前進させることが考えられる。しかしながら、キャリアテープは、部品吸着位置の直前においてカバーテープが剥離されることで収容部品を吸着可能な状態とされるものである。このため、上記の取り出し時にキャリアテープが前進動作すると、カバーテープの剥離が連続して行われることで、キャリアテープ内の収容部品が無駄に消費されてしまう。 By the way, when taking out the carrier tape set in the feeder device from the feeder device at the time of replacement due to non-use or the like, it is conceivable to advance the carrier tape by rotating the sprocket forward. However, the carrier tape is in a state where the housing component can be sucked by peeling the cover tape immediately before the component suction position. For this reason, when the carrier tape moves forward at the time of taking out, the cover tape is continuously peeled, and the housing components in the carrier tape are consumed wastefully.
　そこで、フィーダ装置においてキャリアテープの収容部品を無駄にすることなくそのキャリアテープを取り出すうえで、スプロケットを逆回転させてそのキャリアテープを後退させることが考えられる。キャリアテープが後退動作すれば、カバーテープの剥離は行われないので、キャリアテープ内の収容部品が無駄に消費されるのは回避される。しかしながら、キャリアテープが後退動作した場合、キャリアテープがフィーダ装置内で詰まることがある。 Therefore, in order to take out the carrier tape without wasting the parts accommodated in the feeder tape in the feeder device, it is conceivable to reverse the sprocket and reverse the carrier tape. If the carrier tape moves backward, the cover tape is not peeled off, so that waste of the accommodated parts in the carrier tape is avoided. However, when the carrier tape moves backward, the carrier tape may be jammed in the feeder device.
　例えば、上記特許文献２記載のオートローディング方式のフィーダ装置においては、テープ搬送路上でのキャリアテープの搬送をスムースにするための板バネが設けられている。この板バネは、後部側スプロケットに対する後方（すなわち、テープ搬送方向における上流側）かつテープ搬送路に対する上方に配置されており、テープ挿入部に挿入されたキャリアテープをテープ搬送路の上面に向けて付勢する。この板バネの先端は、テープ挿入部にキャリアテープが挿入されていないときは、テープ搬送路の上面側に当接している。そして、そのテープ挿入部にキャリアテープが挿入されると、そのキャリアテープの先端がその板バネを押し上げ、テープ搬送路と板バネとの間に入り込む。しかし、かかる板バネが設けられた構造においては、キャリアテープの終端がフィーダ装置内にあってかつその板バネの位置に対して前方（すなわち、テープ搬送方向における下流側）に位置するときに、後部側のスプロケットが逆回転されてそのキャリアテープが後退動作すると、そのキャリアテープの終端がその板バネに当接して、そのキャリアテープの後退が阻止される詰まりが生じるおそれがある。 For example, in the autoloading feeder device described in Patent Document 2, a leaf spring is provided for smooth carrier tape transport on the tape transport path. This leaf spring is arranged behind the rear sprocket (that is, upstream in the tape conveyance direction) and above the tape conveyance path, and the carrier tape inserted in the tape insertion portion faces the upper surface of the tape conveyance path. Energize. The tip of the leaf spring is in contact with the upper surface side of the tape conveyance path when the carrier tape is not inserted into the tape insertion portion. When the carrier tape is inserted into the tape insertion portion, the tip of the carrier tape pushes up the leaf spring and enters between the tape conveyance path and the leaf spring. However, in the structure in which such a leaf spring is provided, when the end of the carrier tape is in the feeder device and positioned forward (i.e., downstream in the tape transport direction) with respect to the position of the leaf spring, When the rear side sprocket is reversely rotated and the carrier tape moves backward, the end of the carrier tape comes into contact with the leaf spring, which may cause clogging that prevents the carrier tape from moving backward.
　本発明は、フィーダ装置からのキャリアテープの取り出しを、収容部品の無駄を生じさせることなくかつ詰まりを生じさせることなく適切に行うことが可能なフィーダ装置を提供することを目的とする。 It is an object of the present invention to provide a feeder device that can appropriately carry out the removal of the carrier tape from the feeder device without causing waste of housing parts and without causing clogging.

　本開示によれば、キャリアテープの取り出し要求に従って後部側モータの駆動により後部側スプロケットが正回転するので、その後部側スプロケットに係合しているキャリアテープの終端側がテープ排出部側へ向けて前進される。このため、フィーダの後端側においてキャリアテープの後退に伴ってそのキャリアテープの終端がフィーダを構成する部品に当接する事態が生ずることはない。また、キャリアテープの取り出し要求に従って前部側モータの駆動により前部側スプロケットが逆回転するので、その前部側スプロケットに係合しているキャリアテープの先端側がテープ挿入部側へ向けて後退される。このため、フィーダの前端側においてキャリアテープが前進に伴って収容部品を取り出し可能な状態になるのは回避される。従って、キャリアテープの取り出し時に、フィーダの後端側におけるテープ詰まりの発生を防止することができると共に、キャリアテープの収容部品が無駄に消費されるのを回避することができる。すなわち、フィーダ装置からのキャリアテープの取り出しを、収容部品の無駄を生じさせることなくかつ詰まりを生じさせることなく適切に行うことができる。 According to the present disclosure, since the rear side sprocket rotates normally by driving the rear side motor in accordance with the request for taking out the carrier tape, the terminal side of the carrier tape engaged with the rear side sprocket advances toward the tape discharge unit side. Is done. For this reason, the rear end side of the feeder does not cause a situation in which the end of the carrier tape comes into contact with the parts constituting the feeder as the carrier tape is retracted. In addition, since the front side sprocket rotates in reverse by driving the front side motor in accordance with the carrier tape removal request, the front end side of the carrier tape engaged with the front side sprocket is retracted toward the tape insertion side. The For this reason, it is avoided that the carrier tape becomes ready to be taken out as the carrier tape advances on the front end side of the feeder. Therefore, when the carrier tape is taken out, the occurrence of tape clogging on the rear end side of the feeder can be prevented, and it is possible to avoid wasteful consumption of the parts accommodated in the carrier tape. That is, the carrier tape can be properly taken out from the feeder device without causing waste of the housing components and without causing clogging.

The stop portion 174c is located at a boundary position whether or not the engagement between the engagement hole 81b of the carrier tape 80 whose tip is in contact with the rear surface of the stop portion 174c and the engagement protrusion 121a of the first rear side sprocket 121 occurs. Has been placed. This engagement is realized in a state where the stop portion 174c is separated from the tape transport path 110.
　ストッパ部材１７４には、突出部１７４ｄが設けられている。突出部１７４ｄは、ストッパ部材１７４の、軸支部１７４ａよりも前方の上部に設けられている。突出部１７４ｄは、上方に向けて突出している。突出部１７４ｄの先端には、カムフォロア１７４ｅが設けられている。操作レバー１６５の前部には、カム部１６５ｂが形成されている。カム部１６５ｂは、カムフォロア１７４ｅに係脱可能に係合されている。 The protrusion 174d is provided on the stopper member 174. The projecting portion 174d is provided in the upper portion of the stopper member 174 in front of the shaft support portion 174a. The protrusion 174d protrudes upward. A cam follower 174e is provided at the tip of the protruding portion 174d. A cam portion 165 b is formed at the front portion of the operation lever 165. The cam portion 165b is detachably engaged with the cam follower 174e.
　図７に示す如く、操作レバー１６５がスプリング１７２の付勢力により所定回りに回動され、入口押部材１６３がテープ搬送路１１０に当接する位置に保持されている状態では、操作レバー１６５のカム部１６５ｂがストッパ部材１７４のカムフォロア１７４ｅから離間する。この場合、ストッパ部材１７４は、図略のスプリングの付勢力により軸支部１７４ａを中心にして反対回りに回動されており、当接部１７４ｂをテープ搬送路１１０に当接させると共に、停止部１７４ｃをテープ搬送路１１０から離間させた状態に保持されている。 As shown in FIG. 7, in a state where the operation lever 165 is rotated around a predetermined distance by the urging force of the spring 172 and the inlet pressing member 163 is held at a position where it abuts against the tape transport path 110, the cam portion of the operation lever 165 165b is separated from the cam follower 174e of the stopper member 174. In this case, the stopper member 174 is rotated counterclockwise around the shaft support portion 174a by the biasing force of a spring (not shown), and causes the contact portion 174b to contact the tape transport path 110 and the stop portion 174c. Is held away from the tape transport path 110.
　一方、図９に示す如く、操作レバー１６５がスプリング１７２の付勢力に抗して回動されると、操作レバー１６５のカム部１６５ｂがストッパ部材１７４のカムフォロア１７４ｅに係合する。この場合、ストッパ部材１７４は、図略のスプリングの付勢力に抗して軸支部１７４ａを中心にして所定回りに回動され、停止部１７４ｃをテープ搬送路１１０に当接させる。かかる状態でキャリアテープ８０がテープ挿入部１０１に挿入されると、その挿入されたキャリアテープ８０は、テープ上面付勢部材１７６とテープ下面付勢部材１１２との間に入り込んだ後、その先端がストッパ部材１７４の停止部１７４ｃに当接して停止される。 On the other hand, as shown in FIG. 9, when the operation lever 165 is rotated against the urging force of the spring 172, the cam portion 165b of the operation lever 165 engages with the cam follower 174e of the stopper member 174. In this case, the stopper member 174 is rotated around the shaft support portion 174 a against a biasing force of a spring (not shown) to bring the stop portion 174 c into contact with the tape transport path 110. When the carrier tape 80 is inserted into the tape insertion portion 101 in such a state, the inserted carrier tape 80 enters between the tape upper surface urging member 176 and the tape lower surface urging member 112, and then the tip of the carrier tape 80 is inserted. The stopper member 174 is stopped by coming into contact with the stop portion 174c of the stopper member 174.
　尚、キャリアテープ８０（以下、このキャリアテープ８０を第１キャリアテープ８０－１と称す。）がテープ搬送路１１０とストッパ部材１７４の当接部１７４ｂとの間を通過した後は、その第１キャリアテープ８０－１によって当接部１７４ｂが持ち上げられ、ストッパ部材１７４の停止部１７４ｃがテープ搬送路１１０に当接する。かかる状態で新たなキャリアテープ８０（以下、このキャリアテープ８０を第２キャリアテープ８０－２と称す。）がテープ挿入部１０１に挿入され、第１キャリアテープ８０－１の上に重ねられると、その第２キャリアテープ８０－２は、テープ上面付勢部材１７６とテープ下面付勢部材１１２との間に入り込んだ後、その先端がストッパ部材１７４の停止部１７４ｃに当接して停止される。これにより、第１キャリアテープ８０－１がテープ搬送路１１０上に搬送されている際に、第２キャリアテープ８０－２の下流側への搬送が阻止され、第２キャリアテープ８０－２がその位置で待機される。 Incidentally, after the carrier tape 80 (hereinafter, this carrier tape 80 is referred to as a first carrier tape 80-1) passes between the tape transport path 110 and the contact portion 174b of the stopper member 174, its first The contact portion 174 b is lifted by the carrier tape 80-1, and the stop portion 174 c of the stopper member 174 contacts the tape transport path 110. In this state, when a new carrier tape 80 (hereinafter, this carrier tape 80 is referred to as a second carrier tape 80-2) is inserted into the tape insertion portion 101 and overlaid on the first carrier tape 80-1, The second carrier tape 80-2 enters between the tape upper surface urging member 176 and the tape lower surface urging member 112, and then the tip of the second carrier tape 80-2 comes into contact with the stop portion 174c of the stopper member 174 and is stopped. As a result, when the first carrier tape 80-1 is being transported onto the tape transport path 110, transport of the second carrier tape 80-2 to the downstream side is prevented, and the second carrier tape 80-2 is Wait at position.
　フィーダ２２は、テープ剥離装置１７５を備えている。テープ剥離装置１７５は、フィーダ本体１００の前側上部に取り付けられている。具体的には、第１前部側スプロケット１３１の上流側に配置されている。テープ剥離装置１７５は、キャリアテープ８０からカバーテープ８３を剥離することで、部品移載位置Ｌで収容穴８１ａから部品６０を取り出し吸着可能な状態にするものである。 The feeder 22 includes a tape peeling device 175. The tape peeling device 175 is attached to the upper front side of the feeder main body 100. Specifically, it is arranged on the upstream side of the first front side sprocket 131. The tape peeling device 175 peels the cover tape 83 from the carrier tape 80 so that the component 60 can be taken out from the accommodation hole 81a at the component transfer position L and can be sucked.

The second sensor 182 is turned on by the second dog 192. The second dog 192 is attached to the operation lever 165, and turns on the second sensor 182 when the operation lever 165 rotates about a predetermined direction.
　第３センサ１８３は、キャリアテープ８０がテープ搬送路１１０上において第１後部側スプロケット１２１と係合する位置まで搬送されたか否かに応じた信号、すなわち、キャリアテープ８０と第１後部側スプロケット１２１との係合が生じるか否かの境界位置におけるキャリアテープ８０の有無に応じた信号を出力するセンサである。第３センサ１８３は、第３ドッグ１９３の前端位置の後方におけるキャリアテープ８０の有無に応じた信号を出力し、第３ドッグ１９３の回動位置に応じた信号を出力する。 The third sensor 183 is a signal according to whether or not the carrier tape 80 has been transported to the position where it engages with the first rear sprocket 121 on the tape transport path 110, that is, the carrier tape 80 and the first rear sprocket 121.

The third sensor 183 outputs a signal corresponding to the presence or absence of the carrier tape 80 behind the front end position of the third dog 193 and outputs a signal corresponding to the rotational position of the third dog 193.
　第３ドッグ１９３は、その前後中央部に設けられた軸支部１９３ａにて下流側押部材１６４に回動可能に支持されている。第３ドッグ１９３は、テープ上面付勢部材１７６及びテープ下面付勢部材１１２の上流側に配置されており、第１後部側スプロケット１２１に対して上流側に配置されており、ストッパ部材１７４の停止部１７４ｃよりも上流側に配置されている。第３ドッグ１９３は、テープ挿入部１０１に挿入されたキャリアテープ８０の先端がその第３ドッグ１９３を押し上げてテープ搬送路１１０側との隙間を通じて停止部１７４ｃまで搬送されることができるように形成されている。第３ドッグ１９３は、通常は、スプリング（図示せず）の付勢力により所定回りに回動される。第３ドッグ１９３は、板バネ作用により、テープ搬送路１１０との間にキャリアテープ８０が存在していないときは、その先端をテープ搬送路１１０の上面に当接させ、テープ搬送路１１０との間に第１キャリアテープ８０－１が存在しているときは、その先端をその第１キャリアテープ８０－１の上面に当接させると共に、テープ搬送路１１０との間に第１キャリアテープ８０－１及び第２キャリアテープ８０－２の双方が重なった状態で存在しているときは、その先端をその第２キャリアテープ８０－２の上面に当接させる。 The third dog 193 is rotatably supported by the downstream pressing member 164 at a shaft support portion 193a provided at the front and rear center portion thereof. The third dog 193 is disposed on the upstream side of the tape upper surface biasing member 176 and the tape lower surface biasing member 112, and is disposed upstream of the first rear side sprocket 121, and the stopper member 174 is stopped. It arrange | positions upstream from the part 174c. The third dog 193 is formed so that the tip of the carrier tape 80 inserted into the tape insertion portion 101 can be conveyed up to the stop portion 174c through the gap with the tape conveyance path 110 by pushing up the third dog 193. Has been. The third dog 193 is normally rotated around a predetermined direction by a biasing force of a spring (not shown). When the carrier tape 80 is not present between the third dog 193 and the tape transport path 110 due to the leaf spring action, the third dog 193 is brought into contact with the upper surface of the tape transport path 110 so as to When the first carrier tape 80-1 exists between them, the front end of the first carrier tape 80-1 is brought into contact with the upper surface of the first carrier tape 80-1, and the first carrier tape 80- When both the first carrier tape 80-2 and the second carrier tape 80-2 are overlapped with each other, the tip thereof is brought into contact with the upper surface of the second carrier tape 80-2.
　第４センサ１８４は、第２後部側スプロケット１２２の下流側に搬送されているキャリアテープ８０の有無に応じた信号を出力するセンサである。第４センサ１８４は、第１キャリアテープ８０－１と第２キャリアテープ８０－２との境界部分を検知することが可能である。第５センサ１８５は、第１前部側スプロケット１３１の上流側に搬送されているキャリアテープ８０の有無に応じた信号を出力するセンサである。 The fourth sensor 184 is a sensor that outputs a signal corresponding to the presence or absence of the carrier tape 80 being conveyed downstream of the second rear side sprocket 122. The fourth sensor 184 can detect a boundary portion between the first carrier tape 80-1 and the second carrier tape 80-2. The fifth sensor 185 is a sensor that outputs a signal corresponding to the presence / absence of the carrier tape 80 being conveyed upstream of the first front sprocket 131.
　第１センサ１８１、第２センサ１８２、第３センサ１８３、第４センサ１８４、及び第５センサ１８５の各出力信号は、制御装置４０のマイコン４１に供給される。マイコン４１は、以下の如く、第１センサ１８１、第２センサ１８２、第３センサ１８３、第４センサ１８４、及び第５センサ１８５の各出力信号に基づいて、後部側スプロケット１２０及び前部側スプロケット１３０の回転制御すなわち後部側モータ１４０及び前部側モータ１５０の駆動制御を実行する。 The output signals of the first sensor 181, the second sensor 182, the third sensor 183, the fourth sensor 184, and the fifth sensor 185 are supplied to the microcomputer 41 of the control device 40. The microcomputer 41 performs the rear-side sprocket 120 and the front-side sprocket based on the output signals of the first sensor 181, the second sensor 182, the third sensor 183, the fourth sensor 184, and the fifth sensor 185 as follows. Rotational control 130, that is, drive control of the rear motor 140 and the front motor 150 is executed.
　上記したフィーダ２２において、第１キャリアテープ８０－１は、第１保持部２３ａに保持されるリール７０に巻回されていると共に、第２キャリアテープ８０－２は、第２保持部２３ｂに保持されるリール７１に巻回されている。操作レバー１６５がスプリング１７２の付勢力により保持されている通常状態では、図７に示す如く、入口押部材１６３がテープ搬送路１１０に当接していると共に、邪魔板１７３が自重により回動されてテープ搬送路１１０を閉塞している。 In the feeder 22, the first carrier tape 80-1 is wound around the reel 70 held by the first holding portion 23a, and the second carrier tape 80-2 is held by the second holding portion 23b. The reel 71 is wound around. In the normal state in which the operation lever 165 is held by the urging force of the spring 172, as shown in FIG. 7, the inlet pressing member 163 is in contact with the tape transport path 110 and the baffle plate 173 is rotated by its own weight. The tape transport path 110 is closed.
　上記の状態で操作レバー１６５が持ち上げ操作されると、第２ドッグ１９２が回動されて、その操作レバー１６５の回動が第２センサ１８２により検出されると共に、図９に示す如く作動係合部１６５ａの上昇により入口押部材１６３がスプリング１６７の付勢力に抗して上昇される。この場合には、入口押部材１６３がテープ搬送路１１０から離間すると共に、邪魔板１７３が下流側押部材１６４により回動されて、テープ挿入部１０１をキャリアテープ８０を挿入可能な状態に開放する。また同時に、ストッパ部材１７４が操作レバー１６５のカム部１６５ｂによって回動されて、停止部１７４ｃがテープ搬送路１１０に当接する。 When the operation lever 165 is lifted in the above state, the second dog 192 is rotated, and the rotation of the operation lever 165 is detected by the second sensor 182, and the operation engagement is performed as shown in FIG. As the portion 165a rises, the inlet pushing member 163 is raised against the urging force of the spring 167. In this case, the inlet pressing member 163 is separated from the tape transport path 110, and the baffle plate 173 is rotated by the downstream pressing member 164 to open the tape insertion portion 101 into a state where the carrier tape 80 can be inserted. . At the same time, the stopper member 174 is rotated by the cam portion 165 b of the operation lever 165, and the stop portion 174 c comes into contact with the tape transport path 110.
　上記の状態で第１キャリアテープ８０－１が、その先端がテープ挿入部１０１からテープ搬送路１１０上を通ってストッパ部材１７４の停止部１７４ｃに当接する位置まで挿入されると、その第１キャリアテープ８０－１によって第１ドッグ１９１が下降するので、その第１キャリアテープ８０－１のテープ挿入部１０１への挿入が第１センサ１８１により検出される。また同時に、その挿入された第１キャリアテープ８０－１がテープ上面付勢部材１７６とテープ下面付勢部材１１２との間に入り込んだ後、その第１キャリアテープ８０－１によって第３ドッグ１９３が持ち上げられるので、その停止部１７４ｃに当接している第１キャリアテープ８０－１の存在が第３センサ１８３により検出される。 In the above state, when the first carrier tape 80-1 is inserted from the tape insertion portion 101 to the position where it abuts against the stop portion 174c of the stopper member 174 through the tape conveyance path 110, the first carrier tape 80-1 is inserted. Since the first dog 191 is lowered by the tape 80-1, the insertion of the first carrier tape 80-1 into the tape insertion portion 101 is detected by the first sensor 181. At the same time, after the inserted first carrier tape 80-1 enters between the tape upper surface urging member 176 and the tape lower surface urging member 112, the first carrier tape 80-1 causes the third dog 193 to move. Since it is lifted, the third sensor 183 detects the presence of the first carrier tape 80-1 that is in contact with the stop 174c.
　第１キャリアテープ８０－１が停止部１７４ｃに当接する位置まで挿入された状態で操作レバー１６５の持ち上げ操作が解除されると、その操作レバー１６５がスプリング１７２の付勢力により回動されて原位置に復帰するので、第２センサ１８２がオフされると共に、図１０に示す如く入口押部材１６３がスプリング１６７の付勢力によりテープ搬送路１１０に向けて押圧される。この場合には、入口押部材１６３が第１キャリアテープ８０－１をテープ搬送路１１０に押さえると共に、邪魔板１７３が自重によりテープ挿入部１０１を閉塞する。また同時に、ストッパ部材１７４がスプリングの付勢力によって、当接部１７４ｂをテープ搬送路１１０に当接させると共に、停止部１７４ｃをテープ搬送路１１０から離間させる。 When the lifting operation of the operation lever 165 is released in a state where the first carrier tape 80-1 is inserted to a position where it abuts against the stop portion 174c, the operation lever 165 is rotated by the urging force of the spring 172 and is moved to the original position. Accordingly, the second sensor 182 is turned off, and the inlet pressing member 163 is pressed toward the tape transport path 110 by the urging force of the spring 167 as shown in FIG. In this case, the inlet pressing member 163 presses the first carrier tape 80-1 against the tape transport path 110, and the baffle plate 173 closes the tape insertion portion 101 by its own weight. At the same time, the stopper member 174 causes the contact portion 174 b to contact the tape transport path 110 and the stop portion 174 c away from the tape transport path 110 by the biasing force of the spring.
　制御装置４０において、マイコン４１は、第１センサ１８１により第１キャリアテープ８０－１の挿入を検出し、第３センサ１８３により第１キャリアテープ８０－１の存在を検出し、かつ第２センサ１８２により操作レバー１６５が原位置に復帰していることを検出した場合、後部側モータ１４０を、後部側スプロケット１２１，１２２が正方向に回転するように駆動させる。かかる後部側モータ１４０の駆動が行われると、後部側スプロケット１２１，１２２が正方向に回転される。 In the control device 40, the microcomputer 41 detects the insertion of the first carrier tape 80-1 with the first sensor 181, detects the presence of the first carrier tape 80-1 with the third sensor 183, and detects the second sensor 182. When it is detected that the operating lever 165 has returned to the original position, the rear motor 140 is driven so that the rear sprockets 121 and 122 rotate in the forward direction. When the rear motor 140 is driven, the rear sprockets 121 and 122 are rotated in the forward direction.
　この場合、まず、停止部１７４ｃのテープ搬送路１１０からの離間により第１キャリアテープ８０－１の先端側が停止部１７４ｃから下流側（すなわちテープ排出部１０２側）へ搬送されるのが許容されつつ、第１後部側スプロケット１２１の正回転によりその係合突起１２１ａと第１キャリアテープ８０－１の係合穴８１ｂとが係合してその後の正回転が行われるので、その第１キャリアテープ８０－１が第１後部側スプロケット１２１の正回転によりテープ排出部１０２側に搬送される。かかる搬送が行われると、第１キャリアテープ８０－１によって下流側押部材１６４がスプリング１７０の付勢力に抗して持ち上げられ、その第１キャリアテープ８０－１が下流側押部材１６４とテープ搬送路１１０との間に搬送される。 In this case, first, the leading end side of the first carrier tape 80-1 is allowed to be transported from the stop portion 174c to the downstream side (that is, the tape discharge portion 102 side) due to the separation of the stop portion 174c from the tape transport path 110. Then, the forward rotation of the first rear side sprocket 121 causes the engagement protrusion 121a and the engagement hole 81b of the first carrier tape 80-1 to engage with each other, so that the subsequent forward rotation is performed. −1 is conveyed to the tape discharge unit 102 side by the normal rotation of the first rear sprocket 121. When such conveyance is performed, the downstream pressing member 164 is lifted against the urging force of the spring 170 by the first carrier tape 80-1, and the first carrier tape 80-1 is conveyed to the downstream pressing member 164 and the tape. It is conveyed between the path 110.
　上記の如く、第１後部側スプロケット１２１の係合突起１２１ａは、その第１後部側スプロケット１２１の外周の一部にしか設けられていない。このため、第１キャリアテープ８０－１の係合穴８１ｂに係合突起１２１ａが係合した後、その第１キャリアテープ８０－１は間欠的にテープ排出部１０２側に移動される。従って、第１キャリアテープ８０－１の第１後部側スプロケット１２１側への引き込みが急速に行われるのは回避される。尚、下流側押部材１６４が持ち上げられると、ストッパ部材１７４の軸支部１７４ａ及び第３ドッグ１９３の軸支部１９３ａが一体的に上昇される。 As described above, the engagement protrusion 121a of the first rear side sprocket 121 is provided only on a part of the outer periphery of the first rear side sprocket 121. Therefore, after the engagement protrusion 121a is engaged with the engagement hole 81b of the first carrier tape 80-1, the first carrier tape 80-1 is intermittently moved to the tape discharge portion 102 side. Therefore, rapid pull-in of the first carrier tape 80-1 toward the first rear sprocket 121 is avoided. When the downstream side pressing member 164 is lifted, the shaft support portion 174a of the stopper member 174 and the shaft support portion 193a of the third dog 193 are integrally raised.
　第１後部側スプロケット１２１の正回転による第１キャリアテープ８０－１の搬送が継続すると、その第１キャリアテープ８０－１の係合穴８１ｂに第２後部側スプロケット１２２の係合突起１２２ａが係合する。かかる係合後は、その第１キャリアテープ８０－１が第２後部側スプロケット１２２の正回転によってテープ排出部１０２側に搬送される。上記の如く、第２後部側スプロケット１２２の係合突起１２２ａは、その第２後部側スプロケット１２２の外周全周に亘って設けられている。このため、第１キャリアテープ８０－１の係合穴８１ｂに第２後部側スプロケット１２２の係合突起１２２ａが係合した後は、その第１キャリアテープ８０－１のテープ排出部１０２への移動が短時間で行われる。 When the first carrier tape 80-1 continues to be conveyed by the normal rotation of the first rear side sprocket 121, the engagement protrusion 122a of the second rear side sprocket 122 is engaged with the engagement hole 81b of the first carrier tape 80-1. Match. After such engagement, the first carrier tape 80-1 is conveyed to the tape discharge unit 102 side by the forward rotation of the second rear side sprocket 122. As described above, the engagement protrusion 122 a of the second rear sprocket 122 is provided over the entire outer periphery of the second rear sprocket 122. Therefore, after the engagement protrusions 122a of the second rear side sprocket 122 are engaged with the engagement holes 81b of the first carrier tape 80-1, the movement of the first carrier tape 80-1 to the tape discharge portion 102 is performed. Is done in a short time.
　第２後部側スプロケット１２２の正回転による第１キャリアテープ８０－１の搬送が行われると、まず、その第１キャリアテープ８０－１の先端が、上面押部材１６０の後端部に形成された案内部とテープ搬送路１１０との間から上面押部材１６０の下方に進入する。このため、その第１キャリアテープ８０－１の先端側は、上面押部材１６０によってテープ搬送路１１０からの浮き上がりが抑制された状態で前部側スプロケット１３０に向けて搬送される。 When the first carrier tape 80-1 is conveyed by the forward rotation of the second rear side sprocket 122, first, the tip of the first carrier tape 80-1 is formed at the rear end of the upper surface pressing member 160. It enters below the upper surface pressing member 160 from between the guide portion and the tape transport path 110. For this reason, the leading end side of the first carrier tape 80-1 is conveyed toward the front side sprocket 130 in a state in which the upper surface pressing member 160 suppresses the lift from the tape conveying path 110.
　第２後部側スプロケット１２２の正回転による第１キャリアテープ８０－１の搬送が継続すると、第２後部側スプロケット１２２の正回転によって搬送される第１キャリアテープ８０－１が第５センサ１８５により検出される。制御装置４０のマイコン４１は、第５センサ１８５により第１キャリアテープ８０－１の存在を検出した場合、後部側モータ１４０及び前部側モータ１５０を、後部側スプロケット１２１，１２２及び前部側スプロケット１３１，１３２が正方向に間欠的に回転するように駆動させる。かかる後部側モータ１４０及び前部側モータ１５０の駆動が行われると、後部側スプロケット１２１，１２２及び前部側スプロケット１３１，１３２が正方向に間欠的に回転される。尚、この間欠的な回転の一動作当たりの角度は、キャリアテープ８０に収容された部品６０のピッチ間隔で行われる。 When the conveyance of the first carrier tape 80-1 by the normal rotation of the second rear side sprocket 122 is continued, the first carrier tape 80-1 conveyed by the normal rotation of the second rear side sprocket 122 is detected by the fifth sensor 185. Is done. When the fifth sensor 185 detects the presence of the first carrier tape 80-1, the microcomputer 41 of the control device 40 turns the rear side motor 140 and the front side motor 150 into the rear side sprockets 121 and 122 and the front side sprocket. 131 and 132 are driven to rotate intermittently in the forward direction. When the rear motor 140 and the front motor 150 are driven, the rear sprockets 121 and 122 and the front sprockets 131 and 132 are intermittently rotated in the forward direction. The angle per operation of the intermittent rotation is determined by the pitch interval of the parts 60 accommodated in the carrier tape 80.
　かかる状態で第１キャリアテープ８０－１の係合穴８１ｂに第１前部側スプロケット１３１の係合突起１３１ａが係合すると、その第１キャリアテープ８０－１が第１前部側スプロケット１３１の正回転によってテープ排出部１０２側に搬送されると共に、その搬送中にテープ剥離装置１７５によって第１キャリアテープ８０－１からカバーテープ８３が剥離される。そして、その第１キャリアテープ８０－１の係合穴８１ｂに第２前部側スプロケット１３２の係合突起１３２ａが係合すると、その第１キャリアテープ８０－１が第２前部側スプロケット１３２の正回転によってテープ排出部１０２側に搬送される。尚、後部側スプロケット１２１，１２２及び前部側スプロケット１３１，１３２の間欠的な回転中における回転停止ごとに、第１キャリアテープ８０－１に収容された部品６０は、部品移載位置Ｌに位置決めされる。 In this state, when the engagement protrusion 131a of the first front side sprocket 131 is engaged with the engagement hole 81b of the first carrier tape 80-1, the first carrier tape 80-1 is attached to the first front side sprocket 131. While being transported to the tape discharging unit 102 side by the forward rotation, the cover tape 83 is peeled from the first carrier tape 80-1 by the tape peeling device 175 during the transportation. Then, when the engagement protrusion 132a of the second front side sprocket 132 is engaged with the engagement hole 81b of the first carrier tape 80-1, the first carrier tape 80-1 is attached to the second front side sprocket 132. It is conveyed to the tape discharge unit 102 side by forward rotation. The component 60 accommodated in the first carrier tape 80-1 is positioned at the component transfer position L every time the rear side sprocket 121, 122 and the front side sprocket 131, 132 are rotated intermittently. Is done.
　また、テープ搬送路１１０上における第１キャリアテープ８０－１の搬送中は、その第１キャリアテープ８０－１がストッパ部材１７４の当接部１７４ｂを押圧して持ち上げるので、ストッパ部材１７４がスプリングの付勢力に抗して軸支部１７４ａを中心にして回動される。これにより、ストッパ部材１７４の停止部１７４ｃが第１キャリアテープ８０－１の上面に接して当接する。 Further, during the conveyance of the first carrier tape 80-1 on the tape conveyance path 110, the first carrier tape 80-1 presses and lifts the abutting portion 174b of the stopper member 174, so that the stopper member 174 is a spring. It is rotated about the shaft support 174a against the urging force. As a result, the stop portion 174c of the stopper member 174 contacts and contacts the upper surface of the first carrier tape 80-1.
　かかる状態で、操作レバー１６５が持ち上げられスプリング１７２の付勢力に抗して回動されると、入口押部材１６３がテープ搬送路１１０から離間すると共に、邪魔板１７３がテープ挿入部１０１を開放するので、新たなキャリアテープ８０の挿入が可能となる。そして、新たなキャリアテープ８０である第２キャリアテープ８０－２の先端側がテープ挿入部１０１を通じて第１キャリアテープ８０－１と入口押部材１６３との間に挿入されると、その第２キャリアテープ８０－２の先端がテープ上面付勢部材１７６とテープ下面付勢部材１１２との間に入り込んだ後にストッパ部材１７４の停止部１７４ｃに当接して、その第２キャリアテープ８０－２がその位置で搬送停止される。このため、第２キャリアテープ８０－２の下流側への搬送が阻止される。また、第２キャリアテープ８０－２の先端が停止部１７４ｃに当接する位置まで挿入されると、第３ドッグ１９３がその第２キャリアテープ８０－２により持ち上げられ、その第２キャリアテープ８０－２の存在すなわちテープ搬送路１１０上に二本のキャリアテープ８０が挿入されていることが第３センサ１８３により検出される。 In this state, when the operation lever 165 is lifted and rotated against the urging force of the spring 172, the inlet pressing member 163 is separated from the tape transport path 110, and the baffle plate 173 opens the tape insertion portion 101. Therefore, a new carrier tape 80 can be inserted. When the leading end side of the second carrier tape 80-2, which is a new carrier tape 80, is inserted between the first carrier tape 80-1 and the inlet pressing member 163 through the tape insertion portion 101, the second carrier tape 80-2 is inserted. After the leading end of 80-2 enters between the tape upper surface biasing member 176 and the tape lower surface biasing member 112, it comes into contact with the stop portion 174c of the stopper member 174, and the second carrier tape 80-2 is in that position. The transportation is stopped. For this reason, conveyance of the second carrier tape 80-2 to the downstream side is prevented. When the leading end of the second carrier tape 80-2 is inserted to a position where it abuts against the stop portion 174c, the third dog 193 is lifted by the second carrier tape 80-2, and the second carrier tape 80-2 That is, the third sensor 183 detects that two carrier tapes 80 are inserted on the tape transport path 110.
　上記の如く第２キャリアテープ８０－２が停止部１７４ｃに当接する位置まで挿入された状態で操作レバー１６５の持ち上げ操作が解除されると、その操作レバー１６５がスプリング１７２の付勢力により回動されて原位置に復帰するが、第１キャリアテープ８０－１がストッパ部材１７４の当接部１７４ｂを持ち上げているので、ストッパ部材１７４の停止部１７４ｃによって第２キャリアテープ８０－２の停止が維持される。 When the lifting operation of the operation lever 165 is released in a state where the second carrier tape 80-2 is inserted to the position where it comes into contact with the stop portion 174c as described above, the operation lever 165 is rotated by the biasing force of the spring 172. However, since the first carrier tape 80-1 lifts the contact portion 174b of the stopper member 174, the stop of the second carrier tape 80-2 is maintained by the stop portion 174c of the stopper member 174. The
　上記の如く第２キャリアテープ８０－２の停止が維持されている状態で、第１キャリアテープ８０－１の後端である終端が第２キャリアテープ８０－２の前端である先端よりも下流側に搬送されると、その第２キャリアテープ８０－２が第１キャリアテープ８０－１の上流側にあるテープ搬送路１１０の上面に接して、第２キャリアテープ８０－２の係合穴８１ｂに第１後部側スプロケット１２１の係合突起１２１ａが係合する。そして、第１前部側スプロケット１３１の正回転により、第２キャリアテープ８０－２が、第１キャリアテープ８０－１の存在によってテープ搬送路１１０とストッパ部材１７４との間に形成されている隙間に進入し、テープ排出部１０２側に向けて搬送される。尚、第２キャリアテープ８０－２の先端が当接部１７４ｂを持ち上げると、上述の如く、ストッパ部材１７４がスプリングの付勢力に抗して回動され、停止部１７４ｃによって新たなキャリアテープ８０の進入が阻止される。 In the state where the stop of the second carrier tape 80-2 is maintained as described above, the end that is the rear end of the first carrier tape 80-1 is downstream of the front end that is the front end of the second carrier tape 80-2. The second carrier tape 80-2 comes into contact with the upper surface of the tape conveyance path 110 on the upstream side of the first carrier tape 80-1 and enters the engagement hole 81b of the second carrier tape 80-2. The engagement protrusion 121a of the first rear side sprocket 121 is engaged. Then, due to the forward rotation of the first front sprocket 131, the second carrier tape 80-2 is formed between the tape transport path 110 and the stopper member 174 due to the presence of the first carrier tape 80-1. And is transported toward the tape discharge unit 102 side. When the tip of the second carrier tape 80-2 lifts the abutting portion 174b, the stopper member 174 is rotated against the urging force of the spring as described above, and the new carrier tape 80 is moved by the stop portion 174c. The entry is blocked.
　このように、テープ搬送路１１０において二本のキャリアテープ８０が挿入されていれば、１本目のキャリアテープ８０－１の搬送が終了した際に、２本目のキャリアテープ８０－２の搬送を開始することができる。このため、二本のキャリアテープ８０を重ねた状態で停止部１７４ｃから下流側へ搬送することはなく、二本のキャリアテープ８０を時間的に連続して搬送することができ、キャリアテープ８０に収容されている部品６０の部品移載位置Ｌへの供給を途切れさせることなく連続して行うことができる。また、後部側モータ１４０及び前部側モータ１５０の双方を、各スプロケット１２１，１２２，１３１，１３２が正回転するように駆動させることで、キャリアテープ８０に収容されている部品６０を所定の部品移載位置Ｌまで供給することができる。 In this way, if two carrier tapes 80 are inserted in the tape conveyance path 110, the conveyance of the second carrier tape 80-2 is started when the conveyance of the first carrier tape 80-1 is completed. can do. For this reason, the two carrier tapes 80 are not transported downstream from the stop portion 174c in a state where the two carrier tapes 80 are overlapped, and the two carrier tapes 80 can be transported continuously in time. Supply to the component transfer position L of the accommodated component 60 can be performed continuously without interruption. Further, by driving both the rear side motor 140 and the front side motor 150 so that the sprockets 121, 122, 131, and 132 are normally rotated, the part 60 accommodated in the carrier tape 80 is a predetermined part. It is possible to supply up to the transfer position L.
　＜４．テープ取り出し時における制御＞
　ところで、フィーダ２２にセットされたキャリアテープ８０をそのフィーダ２２から取り出すことがある。制御装置４０は、作業者が入力可能な入力部４２と、作業者が視覚や聴覚で認知可能な警告部４３と、を有している。入力部４２及び警告部４３はそれぞれ、マイコン４１に電気的に接続されている。入力部４２には、少なくとも、フィーダ２２にセットされたキャリアテープ８０の取り出しを要求するもの（例えばスイッチなど）が含まれる。また、警告部４３には、作業者が視認可能な表示画面や聴取可能な警報器などが含まれる。 <4. Control when removing tape>
By the way, the carrier tape 80 set in the feeder 22 may be taken out from the feeder 22. The control device 40 includes an input unit 42 that can be input by an operator, and a warning unit 43 that the operator can recognize visually or audibly. Each of the input unit 42 and the warning unit 43 is electrically connected to the microcomputer 41. The input unit 42 includes at least one that requests removal of the carrier tape 80 set in the feeder 22 (for example, a switch). The warning unit 43 includes a display screen that can be visually recognized by an operator, an alarm device that can be listened to, and the like.
　作業者は、フィーダ２２にセットされたキャリアテープ８０の取り出しを行うことを希望する場合、入力部４２に対してその取り出しを要求する操作を行う。この場合、制御装置４０のマイコン４１は、まず、入力部４２に対する操作に従ってそのキャリアテープ８０の取出要求指令を受信する。そして、マイコン４１は、その受信したキャリアテープ８０の取出要求指令に従って、以下の如く、キャリアテープ８０をフィーダ２２から取り出すために、後部側スプロケット１２０及び前部側スプロケット１３０の回転制御すなわち後部側モータ１４０及び前部側モータ１５０の駆動制御を行う。 When the operator desires to take out the carrier tape 80 set in the feeder 22, the operator performs an operation for requesting the input unit 42 to take out the carrier tape 80. In this case, the microcomputer 41 of the control device 40 first receives an instruction to take out the carrier tape 80 in accordance with an operation on the input unit 42. Then, the microcomputer 41 controls the rotation of the rear side sprocket 120 and the front side sprocket 130, that is, the rear side motor in order to take out the carrier tape 80 from the feeder 22 in accordance with the received request for taking out the carrier tape 80 as follows. 140 and the drive control of the front motor 150 are performed.
　マイコン４１は、図１２に示すステップＳ１００にてキャリアテープ８０の取出要求指令を受信すると、まず、フィーダ２２におけるキャリアテープ８０の搬送位置（具体的には、キャリアテープ８０の終端の位置）を確認する。具体的には、まず、ステップＳ１１０にて第１センサ１８１及び第３センサ１８３を用いてキャリアテープ８０の挿入や存在が検出されるか否かを判別する。 When the microcomputer 41 receives an instruction to take out the carrier tape 80 in step S100 shown in FIG. 12, first, the conveyance position of the carrier tape 80 in the feeder 22 (specifically, the end position of the carrier tape 80) is confirmed. To do. Specifically, first, in step S110, it is determined whether insertion or presence of the carrier tape 80 is detected using the first sensor 181 and the third sensor 183.
　第１センサ１８１によりキャリアテープ８０の挿入が検出されずかつ第３センサ１８３によりキャリアテープ８０の存在が検出されない場合は、キャリアテープ８０が第３ドッグ１９３を持ち上げておらず、第３ドッグ１９３の位置よりも上流側（すなわち、後方側）にキャリアテープ８０が存在していないと判断でき、第３ドッグ１９３に対する下流側にキャリアテープ８０全体が存在している可能性があると判断できる。第３ドッグ１９３の上流側に位置するテープ上面付勢部材１７６とテープ下面付勢部材１１２とは、キャリアテープ８０が介在していないときに互いに当接する部材である。テープ上面付勢部材１７６とテープ下面付勢部材１１２との当接位置よりも下流側には、キャリアテープ８０の後退時に終端が当接し得る部材（例えば、第３ドッグ１９３やストッパ部材１７４の停止部１７４ｃや当接部１７４ｂなど）が存在し得るが、上記のテープ上面付勢部材１７６とテープ下面付勢部材１１２との当接位置は、キャリアテープ８０の後退時に終端が当接してその後退を阻止し得る後退阻止推定位置のうち最上流側の位置である。 When the insertion of the carrier tape 80 is not detected by the first sensor 181 and the presence of the carrier tape 80 is not detected by the third sensor 183, the carrier tape 80 does not lift the third dog 193 and the third dog 193 It can be determined that the carrier tape 80 does not exist on the upstream side (that is, the rear side) from the position, and it can be determined that there is a possibility that the entire carrier tape 80 exists on the downstream side with respect to the third dog 193. The tape upper surface biasing member 176 and the tape lower surface biasing member 112 located on the upstream side of the third dog 193 are members that abut each other when the carrier tape 80 is not interposed. On the downstream side of the contact position between the tape upper surface biasing member 176 and the tape lower surface biasing member 112, a member whose end can be contacted when the carrier tape 80 is retracted (for example, the stop of the third dog 193 or the stopper member 174). Part 174c, contact part 174b, etc.), but the contact position between the tape upper surface biasing member 176 and the tape lower surface biasing member 112 is the end of the carrier tape 80 when the carrier tape 80 is retracted. This is the position on the most upstream side of the estimated position for preventing backward movement.
　第３センサ１８３によりキャリアテープ８０の存在が検出されない場合は、テープ上面付勢部材１７６とテープ下面付勢部材１１２とが互いに当接しており、第３ドッグ１９３の先端がテープ搬送路１１０の上面に当接していると共に、キャリアテープ８０の終端位置によってはストッパ部材１７４の当接部１７４ｂ又は停止部１７４ｃがテープ搬送路１１０の上面に当接している。このため、かかる状況で、終端がテープ上面付勢部材１７６とテープ下面付勢部材１１２との当接位置よりも下流側に位置するキャリアテープ８０の全体が後退されるものとすると、その後退中にキャリアテープ８０の終端が、互いに当接するテープ上面付勢部材１７６又はテープ下面付勢部材１１２、或いは、テープ搬送路１１０の上面に当接する第３ドッグ１９３やストッパ部材１７４の停止部１７４ｃ，当接部１７４ｂに当接してその後退が阻止される事態が生じ得る。 When the presence of the carrier tape 80 is not detected by the third sensor 183, the tape upper surface biasing member 176 and the tape lower surface biasing member 112 are in contact with each other, and the tip of the third dog 193 is the upper surface of the tape transport path 110. Depending on the end position of the carrier tape 80, the contact portion 174 b or the stop portion 174 c of the stopper member 174 is in contact with the upper surface of the tape transport path 110. For this reason, in this situation, if the entire carrier tape 80 whose end is located downstream of the contact position between the tape upper surface biasing member 176 and the tape lower surface biasing member 112 is retracted, Further, the end of the carrier tape 80 is connected to the tape upper surface urging member 176 or the tape lower surface urging member 112 that contacts each other, or the third dog 193 that contacts the upper surface of the tape transport path 110 or the stop portion 174c of the stopper member 174. A situation may occur in which the contact portion 174b abuts and the backward movement is prevented.
　そこで、マイコン４１は、上記ステップＳ１１０にて第１センサ１８１によりキャリアテープ８０の挿入が検出されずかつ第３センサ１８３によりキャリアテープ８０の存在が検出されないと判別した場合は、ステップＳ１２０にて、後部側スプロケット１２０が正回転するように後部側モータ１４０を駆動させ、かつ、前部側スプロケット１３０が逆回転するように前部側モータ１５０を駆動させる制御を実行する。以下、この制御を第１制御と称す。この第１制御が実行されると、図１３に示す如く、第１後部側スプロケット１２１及び第２後部側スプロケット１２２が正回転すると共に、第１前部側スプロケット１３１及び第２前部側スプロケット１３２が逆回転する。 Therefore, if the microcomputer 41 determines in step S110 that the insertion of the carrier tape 80 is not detected by the first sensor 181 and the presence of the carrier tape 80 is not detected by the third sensor 183, in step S120, Control is performed to drive the rear motor 140 so that the rear sprocket 120 rotates forward and to drive the front motor 150 so that the front sprocket 130 rotates backward. Hereinafter, this control is referred to as first control. When the first control is executed, as shown in FIG. 13, the first rear side sprocket 121 and the second rear side sprocket 122 rotate forward, and the first front side sprocket 131 and the second front side sprocket 132. Rotates in reverse.
　第１制御による後部側スプロケット１２１，１２２の正回転の開始時は、キャリアテープ８０の終端は、テープ上面付勢部材１７６とテープ下面付勢部材１１２との当接位置に対して下流側に位置している。このため、後部側スプロケット１２１，１２２が正回転した場合、その後部側スプロケット１２１，１２２（具体的には、少なくとも第２後部側スプロケット１２２）にキャリアテープ８０が係合しているときは、そのキャリアテープ８０の終端側（すなわち、後部側スプロケット１２１，１２２との係合位置よりも上流側の部分全体）がテープ搬送路１１０をテープ排出部１０２側へ向けて前進されるので、そのキャリアテープ８０の終端がテープ上面付勢部材１７６又はテープ下面付勢部材１１２の前端或いは第３ドッグ１９３の前端やストッパ部材１７４の当接部１７４ｂの前端などに当接することはない。尚、キャリアテープ８０が２つの後部側スプロケット１２１，１２２の何れにも係合していないときは、それらの後部側スプロケット１２１，１２２の正回転によるキャリアテープ８０の前進が行われることはないので、この場合は、キャリアテープ８０の終端が、第２後部側スプロケット１２２との係合が解除された状態でその第２後部側スプロケット１２２の下流側に停止維持されて、テープ上面付勢部材１７６やテープ下面付勢部材１１２，第３ドッグ１９３，ストッパ部材１７４などに当接することはない。 At the start of forward rotation of the rear side sprockets 121 and 122 by the first control, the end of the carrier tape 80 is located downstream of the contact position between the tape upper surface biasing member 176 and the tape lower surface biasing member 112. is doing. Therefore, when the rear sprockets 121 and 122 are rotated forward, when the carrier tape 80 is engaged with the rear sprockets 121 and 122 (specifically, at least the second rear sprocket 122), Since the terminal side of the carrier tape 80 (that is, the entire portion upstream from the engagement position with the rear side sprockets 121 and 122) is advanced toward the tape discharge unit 102 side, the carrier tape The end of 80 does not contact the front end of the tape upper surface biasing member 176 or the tape lower surface biasing member 112, the front end of the third dog 193, the front end of the contact portion 174b of the stopper member 174, or the like. When the carrier tape 80 is not engaged with any of the two rear sprockets 121 and 122, the carrier tape 80 is not moved forward by the forward rotation of the rear sprockets 121 and 122. In this case, the end of the carrier tape 80 is stopped and maintained on the downstream side of the second rear sprocket 122 in a state where the engagement with the second rear sprocket 122 is released, and the tape upper surface biasing member 176 is stopped. And the tape lower surface urging member 112, the third dog 193, the stopper member 174, etc.
　また、第１制御により前部側スプロケット１３１，１３２が逆回転した場合は、その前部側スプロケット１３１，１３２（具体的には、少なくとも第１前部側スプロケット１３１）にキャリアテープ８０が係合していれば、そのキャリアテープ８０の先端側（すなわち、前部側スプロケット１３１，１３２との係合位置よりも下流側の部分全体）がテープ搬送路１１０をテープ挿入部１０１側へ向けて後退されるので、テープ剥離装置１７５によるそのキャリアテープ８０からのカバーテープ８３の剥離がそれ以上行われることはない。 Further, when the front sprockets 131 and 132 are rotated in reverse by the first control, the carrier tape 80 is engaged with the front sprockets 131 and 132 (specifically, at least the first front sprocket 131). If this is the case, the leading end side of the carrier tape 80 (that is, the entire portion downstream from the engagement position with the front sprockets 131 and 132) retreats toward the tape insertion portion 101 side. Therefore, the tape peeling device 175 does not peel the cover tape 83 from the carrier tape 80 any more.
　従って、キャリアテープ８０の終端がテープ上面付勢部材１７６とテープ下面付勢部材１１２との当接位置に対して下流側に位置しているときに、後部側スプロケット１２１，１２２が正回転され、かつ、前部側スプロケット１３１，１３２が逆回転されれば、互いに当接しているテープ上面付勢部材１７６及びテープ下面付勢部材１１２の前端やテープ搬送路１１０に当接している第３ドッグ１９３又はストッパ部材１７４の前端にキャリアテープ８０の終端が当接するのを確実に回避して、テープ詰まりの発生を防止することができると共に、キャリアテープ８０に収容されている部品６０がカバーテープ８３の剥離によって無駄に消費されるのを回避することができる。 Therefore, when the terminal end of the carrier tape 80 is located on the downstream side with respect to the contact position between the tape upper surface urging member 176 and the tape lower surface urging member 112, the rear side sprockets 121 and 122 are rotated forward, If the front sprockets 131 and 132 are rotated in the reverse direction, the tape upper surface biasing member 176 and the third dog 193 that are in contact with the front end of the tape lower surface biasing member 112 and the tape conveying path 110 are in contact with each other. Alternatively, it is possible to reliably avoid the end of the carrier tape 80 from coming into contact with the front end of the stopper member 174 to prevent the occurrence of tape clogging, and the component 60 accommodated in the carrier tape 80 can be attached to the cover tape 83. It is possible to avoid wasteful consumption due to peeling.
　上記の如くキャリアテープ８０の終端側が前進されかつその先端側が後退されると、テープ搬送路１１０上でそのキャリアテープ８０の前後中央部に撓みが生じると共に、やがてそのキャリアテープ８０とすべてのスプロケット１２１，１２２，１３１，１３２との係合が解除される。カバー部材１６１が開放されると、フィーダ２２においてそのカバー部材１６１の開放により開口部が現れる。上記したキャリアテープ８０の撓みは、このフィーダ２２の開口部の直下で生じる。第１制御の実行に伴う上記の係合解除後、作業者がカバー部材１６１を開放させると共に上面押部材１６０を持ち上げると、図１４に示す如く、キャリアテープ８０にフィーダ２２の開口部から上方に向けて突出するように撓みが生じる。作業者は、この撓んだキャリアテープ８０を手で掴んでフィーダ２２からその開口部を通じて外部に取り出すことが可能である。 As described above, when the end side of the carrier tape 80 is advanced and the front end side thereof is retracted, the front and rear central portions of the carrier tape 80 are bent on the tape conveyance path 110, and the carrier tape 80 and all the sprockets 121 are eventually formed. , 122, 131, 132 are disengaged. When the cover member 161 is opened, an opening appears in the feeder 22 by opening the cover member 161. The bending of the carrier tape 80 described above occurs immediately below the opening of the feeder 22. When the operator releases the cover member 161 and lifts the upper surface pressing member 160 after the above-described disengagement associated with the execution of the first control, the carrier tape 80 moves upward from the opening of the feeder 22 as shown in FIG. Deflection occurs so as to protrude. An operator can grasp the bent carrier tape 80 with his hand and take it out from the feeder 22 through the opening.
　このように、キャリアテープ８０の終端がテープ上面付勢部材１７６とテープ下面付勢部材１１２との当接位置に対して下流側に位置するときは、後部側モータ１４０及び前部側モータ１５０の駆動を第１制御により実行すれば、フィーダ２２からのキャリアテープ８０の取り出しを、収容する部品６０の無駄を生じさせることなくかつ詰まりを生じさせることなく適切に行うことができる。 As described above, when the end of the carrier tape 80 is located downstream of the contact position between the tape upper surface biasing member 176 and the tape lower surface biasing member 112, the rear motor 140 and the front motor 150 If the drive is executed by the first control, the carrier tape 80 can be appropriately removed from the feeder 22 without causing waste of the component 60 to be accommodated and without causing clogging.
　尚、上記の第１制御の実行時、後部側モータ１４０の駆動による後部側スプロケット１２１，１２２の正回転は、少なくとも、第３センサ１８３がオンしないテープ上面付勢部材１７６とテープ下面付勢部材１１２との当接位置からそれらの後部側スプロケット１２１，１２２の係合突起１２１ａ，１２２ａ（具体的には、より下流側にある第２後部側スプロケット１２２の係合突起１２２ａ）との係合位置までの距離（例えば、６０ｍｍ～８０ｍｍ）に相当する回転量や回転角度だけ行われれば十分である。これは、上記の第１制御は、キャリアテープ８０の終端がテープ上面付勢部材１７６とテープ下面付勢部材１１２との当接位置に対して下流側に位置するときに実行開始される制御であるので、後部側スプロケット１２１，１２２の正回転が最低限、上記の回転量や回転角度だけ行われれば、キャリアテープ８０の終端側が第２後部側スプロケット１２２に対して下流側に移動して、そのキャリアテープ８０と後部側スプロケット１２１，１２２との係合が解除され、無駄に後部側モータ１４０が駆動されることなくキャリアテープ８０の取り出しが容易となるからである。 When the first control is executed, the forward rotation of the rear- side sprockets 121 and 122 by driving the rear-side motor 140 causes at least the tape upper surface biasing member 176 and the tape lower surface biasing member that the third sensor 183 is not turned on. 112 is engaged with the engagement protrusions 121a and 122a of the rear-side sprockets 121 and 122 (specifically, the engagement protrusion 122a of the second rear-side sprocket 122 on the further downstream side) It is sufficient to perform the rotation amount and the rotation angle corresponding to the distance (for example, 60 mm to 80 mm). This is because the first control is started when the end of the carrier tape 80 is positioned downstream of the contact position between the tape upper surface biasing member 176 and the tape lower surface biasing member 112. Therefore, if the forward rotation of the rear side sprockets 121 and 122 is performed at least with the above rotation amount and rotation angle, the terminal side of the carrier tape 80 moves downstream with respect to the second rear side sprocket 122, This is because the engagement between the carrier tape 80 and the rear side sprockets 121 and 122 is released, and the carrier tape 80 can be easily taken out without driving the rear side motor 140 unnecessarily.
　また、上記の第１制御の実行時、前部側モータ１５０の駆動による前部側スプロケット１３１，１３２の逆回転は、少なくとも、テープ排出部１０２から排出されているキャリアテープ８０の先端位置からそれらの前部側スプロケット１３１，１３２の係合突起１３１ａ，１３２ａ（具体的には、より上流側にある第１前部側スプロケット１３１の係合突起１３１ａ）との係合位置までの距離に相当する回転量や回転角度だけ行われれば十分である。これは、上記の第１制御は、それまでテープ搬送路１１０に沿って搬送されていたキャリアテープ８０に対して行われるものであり、そのキャリアテープ８０の先端側はテープ排出部１０２から排出されており、そのキャリアテープ８０はテープ排出部１０２からある程度の排出部分でカットされて、上記の距離は一般的に定められたもの（例えば、３００ｍｍ～４００ｍｍ）であるので、前部側スプロケット１３１，１３２の逆回転が最低限、上記の回転量や回転角度だけ行われれば、キャリアテープ８０の先端が第１前部側スプロケット１３１に対して上流側に移動して、そのキャリアテープ８０と前部側スプロケット１３１，１３２との係合が解除され、無駄に前部側モータ１５０が駆動されることなくキャリアテープ８０の取り出しが容易となるからである。尚、上記の第１制御における前部側スプロケット１３１，１３２の逆回転は、上記係合解除を確実なものとするため、作業者の入力部４２への操作などが行われるまで継続して行われるものであってもよい。 Further, during the execution of the first control, the reverse rotation of the front sprockets 131 and 132 due to the driving of the front motor 150 causes at least the front end position of the carrier tape 80 discharged from the tape discharge unit 102 to move. This corresponds to the distance to the engagement position with the engagement protrusions 131a and 132a of the front sprockets 131 and 132 (specifically, the engagement protrusion 131a of the first front sprocket 131 on the more upstream side). It is sufficient to perform only the rotation amount and rotation angle. This is because the first control is performed on the carrier tape 80 that has been transported along the tape transport path 110 until then, and the leading end side of the carrier tape 80 is ejected from the tape ejection section 102. The carrier tape 80 is cut at a certain discharge portion from the tape discharge portion 102, and the above distance is generally determined (for example, 300 mm to 400 mm). If the reverse rotation of 132 is performed at least by the above rotation amount and rotation angle, the tip of the carrier tape 80 moves upstream with respect to the first front sprocket 131, and the carrier tape 80 and the front The engagement with the side sprockets 131 and 132 is released, and the carrier tape 80 is taken out without the front motor 150 being driven unnecessarily. This is because it is easy. The reverse rotation of the front- side sprockets 131 and 132 in the first control is continued until the operator operates the input unit 42 in order to ensure the disengagement. May be used.
　また、第１センサ１８１及び第３センサ１８３のうち少なくとも第３センサ１８３によりキャリアテープ８０の存在が検出される場合は、そのキャリアテープ８０が第３ドッグ１９３を持ち上げているので、第３ドッグ１９３の位置よりも上流側（すなわち、後方側）にキャリアテープ８０が存在していると判断でき、そのキャリアテープ８０の先端が停止部１７４ｃに当接していることを含め、そのキャリアテープ８０が第３ドッグ１９３の前後を挟んで存在していると判断でき、キャリアテープ８０の終端が第３ドッグ１９３よりも上流側（後方）に位置していると判断できる。この場合は、第３ドッグ１９３の先端がテープ搬送路１１０上のキャリアテープ８０の上面に当接していると共に、テープ上面付勢部材１７６とテープ下面付勢部材１１２とがキャリアテープ８０を挟み込んでいる。このため、かかる状況でキャリアテープ８０が後退された場合、その後退中にキャリアテープ８０の終端がテープ上面付勢部材１７６又はテープ下面付勢部材１１２の前端や第３ドッグ１９３又はストッパ部材１７４の前端に当接することはなく、その後退が阻止される事態は生じない。 When the presence of the carrier tape 80 is detected by at least the third sensor 183 out of the first sensor 181 and the third sensor 183, the carrier tape 80 lifts the third dog 193. It can be determined that the carrier tape 80 exists on the upstream side (that is, the rear side) of the position of the carrier tape 80, and the carrier tape 80 includes the first end of the carrier tape 80 in contact with the stop portion 174c. It can be determined that the front and rear of the 3 dog 193 are present, and it can be determined that the end of the carrier tape 80 is located upstream (rearward) from the third dog 193. In this case, the tip of the third dog 193 is in contact with the upper surface of the carrier tape 80 on the tape transport path 110, and the tape upper surface biasing member 176 and the tape lower surface biasing member 112 sandwich the carrier tape 80. Yes. For this reason, when the carrier tape 80 is retracted in such a situation, the end of the carrier tape 80 is the front end of the tape upper surface urging member 176 or the tape lower surface urging member 112, the third dog 193, or the stopper member 174 during the retraction. There will be no contact with the front end, and there will be no situation where the retreat is prevented.
　但し、テープ挿入部１０１に二本のキャリアテープ８０が挿入されており、第１キャリアテープ８０－１がテープ搬送路１１０上で搬送される一方、第２キャリアテープ８０－２がその先端にて停止部１７４ｃに当接して待機しているときは、テープ搬送路１１０上で第１キャリアテープ８０－１と第２キャリアテープ８０－２とが重なるので、第３センサ１８３により第２キャリアテープ８０－２の存在が検出される。そして、その後、第１キャリアテープ８０－１の終端が第２キャリアテープ８０－２の先端よりも下流側に搬送されると、第１キャリアテープ８０－１の終端がテープ上面付勢部材１７６とテープ下面付勢部材１１２との当接位置に対して下流側にあるテープ搬送路１１０上に位置すると共に、その第２キャリアテープ８０－２が第１キャリアテープ８０－１の上流側にあるテープ搬送路１１０の上面に当接することとなる。かかる状況で第１キャリアテープ８０－１が後退されるものとすると、その後退中に第１キャリアテープ８０－１の終端がテープ上面付勢部材１７６又はテープ下面付勢部材１１２の前端や第３ドッグ１９３又はストッパ部材１７４の前端に当接してその後退が阻止される事態が生じ得る。 However, two carrier tapes 80 are inserted into the tape insertion portion 101, and the first carrier tape 80-1 is transported on the tape transport path 110, while the second carrier tape 80-2 is at its tip. When waiting in contact with the stop portion 174c, the first carrier tape 80-1 and the second carrier tape 80-2 overlap on the tape transport path 110, so that the third sensor 183 causes the second carrier tape 80-1 to overlap. -2 is detected. After that, when the end of the first carrier tape 80-1 is transported downstream from the tip of the second carrier tape 80-2, the end of the first carrier tape 80-1 is connected to the tape upper surface biasing member 176. The second carrier tape 80-2 is located on the upstream side of the first carrier tape 80-1 and is located on the tape conveyance path 110 on the downstream side with respect to the contact position with the tape lower surface urging member 112. It comes into contact with the upper surface of the conveyance path 110. Assuming that the first carrier tape 80-1 is retracted in such a situation, the terminal end of the first carrier tape 80-1 during the retraction is the front end of the tape upper surface biasing member 176 or the tape lower surface biasing member 112 or the third end. A situation may occur in which the dog 193 or the stopper member 174 abuts on the front end and is prevented from retreating.
　そこで、マイコン４１は、上記ステップＳ１１０にて第３センサ１８３によりキャリアテープ８０の存在が検出されかつステップＳ１３０にてその存在が検出されるキャリアテープ８０が第１キャリアテープ８０－１のみであると判別した場合は、ステップＳ１４０にて、後部側スプロケット１２０及び前部側スプロケット１３０の双方が逆回転するように後部側モータ１４０及び前部側モータ１５０を駆動させる制御を実行する。以下、この制御を第２制御と称す。この第２制御が実行されると、図１５に示す如く、第１後部側スプロケット１２１、第２後部側スプロケット１２２、第１前部側スプロケット１３１、及び第２前部側スプロケット１３２のすべてが逆回転する。 Therefore, the microcomputer 41 detects that the presence of the carrier tape 80 is detected by the third sensor 183 in step S110 and that the presence of the carrier tape 80 is detected in step S130 is only the first carrier tape 80-1. If it is determined, in step S140, control is performed to drive the rear motor 140 and the front motor 150 so that both the rear sprocket 120 and the front sprocket 130 rotate in reverse. Hereinafter, this control is referred to as second control. When the second control is executed, as shown in FIG. 15, the first rear sprocket 121, the second rear sprocket 122, the first front sprocket 131, and the second front sprocket 132 are all reversed. Rotate.
　第２制御による各スプロケット１２１，１２２，１３１，１３２の逆回転の開始時は、第１キャリアテープ８０－１の終端は、テープ上面付勢部材１７６とテープ下面付勢部材１１２との当接位置に対して上流側に位置している。このため、各スプロケット１２１，１２２，１３１，１３２が逆回転した場合は、第１キャリアテープ８０－１の終端がテープ上面付勢部材１７６又はテープ下面付勢部材１１２の前端や第３ドッグ１９３又はストッパ部材１７４の前端に当接することはなく、その第１キャリアテープ８０－１がテープ上面付勢部材１７６とテープ下面付勢部材１１２との間、第３ドッグ１９３とテープ搬送路１１０との間、及びストッパ部材１７４とテープ搬送路１１０との間を上流側に向けて通過することが可能となるので、キャリアテープ８０を、テープ搬送路１１０上においてテープ排出部１０２側からテープ挿入部１０１側へ向けて適切に後退させることができる。また、前部側スプロケット１３１，１３２が逆回転した場合は、テープ剥離装置１７５によるそのキャリアテープ８０からのカバーテープ８３の剥離がそれ以上行われることはない。 At the start of reverse rotation of each sprocket 121, 122, 131, 132 by the second control, the end of the first carrier tape 80-1 is the contact position between the tape upper surface biasing member 176 and the tape lower surface biasing member 112. It is located on the upstream side. Therefore, when the sprockets 121, 122, 131, 132 are rotated in the reverse direction, the terminal end of the first carrier tape 80-1 is the front end of the tape upper surface biasing member 176 or the tape lower surface biasing member 112, the third dog 193, or the like. The first carrier tape 80-1 is not in contact with the front end of the stopper member 174, and the first carrier tape 80-1 is between the tape upper surface biasing member 176 and the tape lower surface biasing member 112, and between the third dog 193 and the tape transport path 110. , And between the stopper member 174 and the tape transport path 110 toward the upstream side, the carrier tape 80 can be moved from the tape discharge section 102 side to the tape insertion section 101 side on the tape transport path 110. Can be moved back appropriately. Further, when the front sprockets 131 and 132 are rotated in the reverse direction, the tape peeling device 175 does not peel the cover tape 83 from the carrier tape 80 any more.
　キャリアテープ８０の後退が継続すると、そのキャリアテープ８０とすべてのスプロケット１２１，１２２，１３１，１３２との係合が順に解除される。このため、その係合解除後は、キャリアテープ８０の先端が、最も上流側にある第１後部側スプロケット１２１に対して後方に位置することとなるので、作業者がそのキャリアテープ８０をフィーダ２２の後部から引き出して外部に取り出すことが可能となる。 When the backward movement of the carrier tape 80 continues, the engagement between the carrier tape 80 and all the sprockets 121, 122, 131, 132 is sequentially released. For this reason, since the front end of the carrier tape 80 is positioned rearward with respect to the first rear side sprocket 121 located on the most upstream side after the engagement is released, the operator holds the carrier tape 80 on the feeder 22. It can be pulled out from the rear and taken out to the outside.
　このように、キャリアテープ８０の終端がテープ上面付勢部材１７６とテープ下面付勢部材１１２との当接位置に対して上流側に位置するときは、後部側モータ１４０及び前部側モータ１５０の駆動を第２制御により実行すれば、フィーダ２２からのキャリアテープ８０の取り出しを、収容する部品６０の無駄を生じさせることなくかつ詰まりを生じさせることなく適切に行うことができる。 As described above, when the end of the carrier tape 80 is located on the upstream side of the contact position between the tape upper surface biasing member 176 and the tape lower surface biasing member 112, the rear motor 140 and the front motor 150 If the drive is executed by the second control, the carrier tape 80 can be appropriately removed from the feeder 22 without causing waste of the component 60 to be accommodated and without causing clogging.
　また、キャリアテープ８０の終端がテープ上面付勢部材１７６とテープ下面付勢部材１１２との当接位置に対して上流側に位置するか或いは下流側に位置するかに応じて、後部側モータ１４０及び前部側モータ１５０の駆動制御を第１制御と第２制御とで変更するので、キャリアテープ８０の終端位置に何れの位置にあっても、フィーダ２２からのキャリアテープ８０の取り出しを、収容する部品６０の無駄を生じさせることなくかつ詰まりを生じさせることなく適切に行うことができる。更に、このキャリアテープ８０の取り出しを実現するうえで、作業者は、入力部４２に対してキャリアテープ８０の取り出しを要求する一の操作を行うこととすれば十分であり、制御装置４０のマイコン４１がキャリアテープ８０の終端位置を検出してモータ１４０，１５０の駆動制御を第１制御と第２制御とで変更する（特に、後部側スプロケット１２１，１２２の回転方向を変更する）。このため、作業者がキャリアテープ８０の終端位置を知ることなく入力部４２に対して上記の取り出し要求操作を行うこととすればよいので、フィーダ２２からキャリアテープ８０を取り出すうえで、作業者の作業負担の軽減を図ることが可能である。 Further, the rear side motor 140 depends on whether the end of the carrier tape 80 is located on the upstream side or the downstream side with respect to the contact position between the tape upper surface biasing member 176 and the tape lower surface biasing member 112. Since the drive control of the front motor 150 is changed between the first control and the second control, the removal of the carrier tape 80 from the feeder 22 is accommodated at any end position of the carrier tape 80. It is possible to appropriately carry out without causing waste of the component 60 to be performed and without causing clogging. Further, in realizing the removal of the carrier tape 80, it is sufficient for the operator to perform one operation for requesting the removal of the carrier tape 80 from the input unit 42. 41 detects the end position of the carrier tape 80 and changes the drive control of the motors 140 and 150 between the first control and the second control (particularly, changes the rotation direction of the rear-side sprockets 121 and 122). For this reason, since it is only necessary for the operator to perform the above-described extraction request operation on the input unit 42 without knowing the end position of the carrier tape 80, when the operator removes the carrier tape 80 from the feeder 22, It is possible to reduce the work load.
　また、マイコン４１は、上記ステップＳ１１０にて第３センサ１８３によりキャリアテープ８０の存在が検出され、かつ、その存在が検出されるキャリアテープ８０が第１キャリアテープ８０－１のみでないと判別した場合すなわちその第１キャリアテープ８０－１が存在しつつその第１キャリアテープ８０－１の上流側に隣接して第２キャリアテープ８０－２が存在すると判別した場合は、上記ステップＳ１２０にて、後部側スプロケット１２０が正回転するように後部側モータ１４０を駆動させ、かつ、前部側スプロケット１３０が逆回転するように前部側モータ１５０を駆動させる第１制御を実行する。この場合は、図１６に示す如く、第１後部側スプロケット１２１及び第２後部側スプロケット１２２が正回転すると共に、第１前部側スプロケット１３１及び第２前部側スプロケット１３２が逆回転する。 If the microcomputer 41 detects the presence of the carrier tape 80 by the third sensor 183 in step S110 and determines that the carrier tape 80 from which the presence is detected is not only the first carrier tape 80-1. That is, when it is determined that the second carrier tape 80-2 exists adjacent to the upstream side of the first carrier tape 80-1 while the first carrier tape 80-1 is present, The first control is executed to drive the rear motor 140 so that the side sprocket 120 rotates forward and to drive the front motor 150 so that the front sprocket 130 rotates backward. In this case, as shown in FIG. 16, the first rear side sprocket 121 and the second rear side sprocket 122 rotate normally, and the first front side sprocket 131 and the second front side sprocket 132 rotate reversely.
　尚、第３センサ１８３により存在が検出されるキャリアテープ８０が第１キャリアテープ８０－１のみでないとの判別は、第２キャリアテープ８０－２がストッパ部材１７４の停止部１７４ｃに当接して停止した際に第３センサ１８３により二本のキャリアテープ８０が存在することが検出され、その検出が記憶された後、第１キャリアテープ８０－１の終端が第２キャリアテープ８０－２の先端よりも下流側に搬送されてその第２キャリアテープ８０－２がテープ搬送路１１０の上面に接した際に第３センサ１８３により一本のキャリアテープ８０が存在することが検出されることを含む。 The determination that the carrier tape 80 whose presence is detected by the third sensor 183 is not the only first carrier tape 80-1 is made by stopping the second carrier tape 80-2 in contact with the stop portion 174c of the stopper member 174. When the third sensor 183 detects the presence of the two carrier tapes 80 and stores the detection, the end of the first carrier tape 80-1 is moved from the end of the second carrier tape 80-2. The third sensor 183 detects that one carrier tape 80 exists when the second carrier tape 80-2 is conveyed downstream and the second carrier tape 80-2 contacts the upper surface of the tape conveyance path 110.
　第３センサ１８３により二本のキャリアテープ８０が存在することが検出された後に一本のキャリアテープ８０が存在することが検出された場合は、第１キャリアテープ８０－１の終端がテープ上面付勢部材１７６とテープ下面付勢部材１１２との当接位置に対して下流側に位置して、第３センサ１８３により検出されるキャリアテープ８０が第２キャリアテープ８０－２の一本である可能性がある。これに対して、本実施形態においては、かかる検出がなされたときは、上記の第１制御により後部側スプロケット１２１，１２２が正回転する。このため、後部側スプロケット１２１，１２２（具体的には、少なくとも第２後部側スプロケット１２２）に第１キャリアテープ８０－１が係合しているときは、その第１キャリアテープ８０－１の終端側がテープ搬送路１１０をテープ排出部１０２側へ向けて前進されるので、その第１キャリアテープ８０－１の終端がテープ上面付勢部材１７６又はテープ下面付勢部材１１２の前端や第３ドッグ１９３又はストッパ部材１７４の前端に当接することはない。尚、第１キャリアテープ８０－１が２つの後部側スプロケット１２１，１２２の何れにも係合していないときは、それらの後部側スプロケット１２１，１２２の正回転による第１キャリアテープ８０－１の前進が行われることはないので、この場合も第１キャリアテープ８０－１の終端がテープ上面付勢部材１７６又はテープ下面付勢部材１１２の前端や第３ドッグ１９３又はストッパ部材１７４の前端に当接することはない。 When the third sensor 183 detects the presence of one carrier tape 80 after the presence of the two carrier tapes 80 is detected, the end of the first carrier tape 80-1 is attached to the upper surface of the tape. The carrier tape 80 that is located downstream of the contact position between the biasing member 176 and the tape lower surface biasing member 112 and detected by the third sensor 183 may be one of the second carrier tapes 80-2. There is sex. On the other hand, in this embodiment, when such a detection is made, the rear side sprockets 121 and 122 are normally rotated by the first control. Therefore, when the first carrier tape 80-1 is engaged with the rear-side sprockets 121 and 122 (specifically, at least the second rear-side sprocket 122), the end of the first carrier tape 80-1 Since the side is advanced toward the tape discharge section 102 side, the end of the first carrier tape 80-1 is the front end of the tape upper surface biasing member 176 or the tape lower surface biasing member 112 and the third dog 193. Or it does not contact the front end of the stopper member 174. When the first carrier tape 80-1 is not engaged with any of the two rear sprockets 121, 122, the first carrier tape 80-1 is rotated by the forward rotation of the rear sprockets 121, 122. In this case as well, the end of the first carrier tape 80-1 does not contact the front end of the tape upper surface urging member 176 or the tape lower surface urging member 112 or the front end of the third dog 193 or the stopper member 174. There is no contact.
　また、第１制御により前部側スプロケット１３１，１３２が逆回転した場合は、その前部側スプロケット１３１，１３２（具体的には、少なくとも第１前部側スプロケット１３１）に第１キャリアテープ８０－１が係合していれば、その第１キャリアテープ８０－１の先端側がテープ搬送路１１０をテープ挿入部１０１側へ向けて後退されるので、テープ剥離装置１７５によるその第１キャリアテープ８０－１からのカバーテープ８３の剥離がそれ以上行われることはない。 Further, when the front sprockets 131 and 132 are reversely rotated by the first control, the first carrier tape 80- is applied to the front sprockets 131 and 132 (specifically, at least the first front sprocket 131). 1 is engaged, the tip side of the first carrier tape 80-1 is retracted toward the tape insertion portion 101 side of the first carrier tape 80-1, so that the first carrier tape 80- No further peeling of the cover tape 83 from 1 is performed.
　従って、テープ挿入部１０１に二本のキャリアテープ８０が挿入されており、第１キャリアテープ８０－１の終端がテープ上面付勢部材１７６とテープ下面付勢部材１１２との当接位置に対して下流側に位置しかつ第２キャリアテープ８０－２の先端がテープ上面付勢部材１７６とテープ下面付勢部材１１２との当接位置に対して上流側に位置しているときに、後部側スプロケット１２１，１２２が正回転され、かつ、前部側スプロケット１３１，１３２が逆回転されれば、第１キャリアテープ８０－１の終端がテープ上面付勢部材１７６又はテープ下面付勢部材１１２の前端や第３ドッグ１９３又はストッパ部材１７４の前端に当接するのを確実に回避してテープ詰まりの発生を防止することができると共に、第１キャリアテープ８０－１に収容されている部品６０がカバーテープ８３の剥離によって無駄に消費されるのを回避することができる。このため、テープ挿入部１０１に二本のキャリアテープ８０が挿入されていても、フィーダ２２からの第１キャリアテープ８０－１の取り出しを、収容する部品６０の無駄を生じさせることなくかつ詰まりを生じさせることなく適切に行うことができる。 Accordingly, the two carrier tapes 80 are inserted into the tape insertion portion 101, and the end of the first carrier tape 80-1 is in contact with the contact position between the tape upper surface biasing member 176 and the tape lower surface biasing member 112. The rear-side sprocket is located on the downstream side and the tip of the second carrier tape 80-2 is located upstream with respect to the contact position between the tape upper surface biasing member 176 and the tape lower surface biasing member 112. If 121 and 122 are normally rotated and the front side sprockets 131 and 132 are reversely rotated, the end of the first carrier tape 80-1 is the front end of the tape upper surface biasing member 176 or the tape lower surface biasing member 112, The occurrence of tape clogging can be prevented by reliably avoiding contact with the front end of the third dog 193 or the stopper member 174, and the first carrier tape 80- Component 60 housed can be prevented from being wastefully consumed by the peeling of the cover tape 83. For this reason, even when two carrier tapes 80 are inserted into the tape insertion portion 101, the removal of the first carrier tape 80-1 from the feeder 22 can be performed without causing waste of the components 60 to be accommodated. It can be done appropriately without causing it.
　また、テープ搬送路１１０に二本のキャリアテープ８０が挿入されているか否かに応じて、後部側モータ１４０及び前部側モータ１５０の駆動制御を第１制御と第２制御とで変更するので、テープ搬送路１１０に挿入されているキャリアテープ８０が１本であっても２本であっても、フィーダ２２からのキャリアテープ８０の取り出しを、収容する部品６０の無駄を生じさせることなくかつ詰まりを生じさせることなく適切に行うことができる。更に、このキャリアテープ８０の取り出しを実現するうえで、作業者は、入力部４２に対してキャリアテープ８０の取り出しを要求する一の操作を行うこととすれば十分であり、制御装置４０のマイコン４１がテープ搬送路１１０に二本のキャリアテープ８０が挿入されているか否かを判別してモータ１４０，１５０の駆動制御を第１制御と第２制御とで変更する（特に、後部側スプロケット１２１，１２２の回転方向を変更する）。このため、作業者がテープ搬送路１１０に二本のキャリアテープ８０が挿入されているか否かを知ることなく入力部４２に対して上記の取り出し要求操作を行うこととすればよいので、フィーダ２２からキャリアテープ８０を取り出すうえで、作業者の作業負担の軽減を図ることが可能である。 Further, the drive control of the rear side motor 140 and the front side motor 150 is changed between the first control and the second control depending on whether or not the two carrier tapes 80 are inserted in the tape transport path 110. Whether the carrier tape 80 inserted into the tape conveyance path 110 is one or two, the removal of the carrier tape 80 from the feeder 22 can be performed without causing waste of the components 60 to be accommodated. It can be carried out appropriately without causing clogging. Further, in realizing the removal of the carrier tape 80, it is sufficient for the operator to perform one operation for requesting the removal of the carrier tape 80 from the input unit 42. 41 determines whether or not two carrier tapes 80 are inserted in the tape transport path 110, and changes the drive control of the motors 140 and 150 between the first control and the second control (particularly, the rear sprocket 121). , 122 is changed). For this reason, it is only necessary for the operator to perform the above-described take-out request operation on the input unit 42 without knowing whether or not the two carrier tapes 80 are inserted in the tape transport path 110. When taking out the carrier tape 80 from the operator, it is possible to reduce the work load on the operator.

　＜５．変形形態＞
　ところで、上記の実施形態においては、第１制御の実行に伴う後部側スプロケット１２１，１２２の正回転かつ前部側スプロケット１３１，１３２の逆回転により撓みが生じるキャリアテープ８０を、作業者がフィーダ２２のカバー部材１６１を開放してその開口部を通じて外部に取り出す。すなわち、この撓みが生じるキャリアテープ８０をフィーダ２２から取り出すうえでは、作業者がカバー部材１６１を開放し更には上面押部材１６０を持ち上げることで開口部を作ることが必要である。仮にカバー部材１６１が開放されず或いは上面押部材１６０が持ち上げられないと、テープ搬送路１１０上でキャリアテープ８０が撓んでフィーダ２２内部でそのキャリアテープ８０が絡む或いは捩れるおそれがある。 <5. Variant>
By the way, in the above embodiment, the operator uses the carrier tape 80 in which the carrier 22 is bent by the forward rotation of the rear sprockets 121 and 122 and the reverse rotation of the front sprockets 131 and 132 accompanying the execution of the first control. The cover member 161 is opened and taken out through the opening. That is, in order to take out the carrier tape 80 in which this bending occurs from the feeder 22, it is necessary for the operator to open the cover member 161 and further lift the upper surface pressing member 160 to create an opening. If the cover member 161 is not opened or the upper surface pressing member 160 is not lifted, the carrier tape 80 may be bent on the tape conveyance path 110 and the carrier tape 80 may be entangled or twisted inside the feeder 22.
　そこで、テープ搬送路１１０上のキャリアテープ８０の撓みを検知するための撓み検知センサを設け、制御装置４０のマイコン４１がその撓み検知センサを用いてその撓みを検知した場合に警告部４３を用いてその撓みを作業者に知らせてカバー部材１６１の開放や上面押部材１６０の持ち上げを促す表示や警報などの警告を行うこととしてもよい。かかる変形形態によれば、警告部４３を通じて作業者に第１制御の実行に伴うキャリアテープ８０の撓みを認知させて、カバー部材１６１の開放や上面押部材１６０の持ち上げを促すことができるので、第１制御の実行中や実行後におけるフィーダ２２の開口部を通じたキャリアテープ８０の取り出しを促すことができる。 Therefore, a bending detection sensor for detecting the bending of the carrier tape 80 on the tape conveyance path 110 is provided, and the warning unit 43 is used when the microcomputer 41 of the control device 40 detects the bending using the bending detection sensor.

Stop control for stopping the driving of the motors 140 and 150 is performed, and after stopping the driving of the motors 140 and 150 according to the detection of the bending of the carrier tape 80 by the stop control during the execution of the first control, the opening / closing detection sensor is used. When the opening of the cover member 161 is detected, the execution of the first control may be automatically restarted even if the bending of the carrier tape 80 is detected using the bending detection sensor.
　この変形形態の構成によれば、第１制御の実行中に撓み検知センサを用いた停止制御が行われた場合でも、カバー部材１６１が開放されたときは、キャリアテープ８０の撓みをカバー部材１６１の開放によるフィーダ２２の開口部を通じて外部に飛び出させた状態に形成することができるので、停止制御の実行後、作業者に専用の操作を強いることなく、キャリアテープ８０の撓みを取り出し容易に形成することができる。 According to the configuration of this modification, even when the stop control using the deflection detection sensor is performed during the execution of the first control, when the cover member 161 is opened, the bending of the carrier tape 80 is performed.
