　従来から、連続運転中のベルトコンベア上の搬送物を種類別に選別する装置としては、搬送方向に対して左右方向から、搬送物にエアシリンダによる押し出し等の外力を加えて、ベルトコンベア外（例えば、他のベルトコンベアや排出シュート等）に排出し、選別するものが知られている。 Conventionally, as a device that sorts the conveyed items on the belt conveyor during continuous operation by type, external force such as extrusion by an air cylinder is applied to the conveyed items from the left and right directions with respect to the conveying direction, and the outside of the belt conveyor (for example, Other belt conveyors, discharge chutes, etc.) that are discharged and sorted are known.
　また、特許文献１には、多品種多形状の部品を各印刷基板の製造に使用するよう各工程に仕分けして供給する多品種多形状電気部品の仕分け装置が開示されている。この仕分け装置は、コンベア上に搬送される電気部品の長さを測る測長部と、バーコードを読み取るバーコードリーダと、仕分けの制御を行う制御部と、多品種多形状の電気部品をそれぞれ実装するための複数の製品番号に対応する図番別に仕分けるための仕分け部と、を備えている。 Also, Patent Document 1 discloses a multi-variety multi-shaped electrical component sorting apparatus that sorts and supplies various types of multi-shaped components for use in the production of each printed circuit board. This sorting device is provided with a length measuring unit for measuring the length of an electrical component conveyed on a conveyor, a barcode reader for reading a barcode, a control unit for controlling sorting, and a variety of various types of electrical components. And a sorting unit for sorting by drawing number corresponding to a plurality of product numbers for mounting.
　仕分け部は、電気部品が投入されると搬送を行う仕分け用コンベアと、仕分け用コンベアの両側に配置されて電気部品を収納する多数のシュータと、を備える。仕分け用コンベアは、バーコードリーダにより識別した結果に対応して制御部の制御により、進行方向と直交する２つの方向のうち、一方の指定されたシュータに投入するよう駆動される。このように構成することで、多形状且つ多重量の電機部品を高速で多数のシュータに振り分けることを図っている。 The sorting unit includes a sorting conveyor that transports when an electrical component is inserted, and a large number of shooters that are arranged on both sides of the sorting conveyor to store the electrical component. The sorting conveyor is driven to be fed into one designated shooter out of two directions orthogonal to the traveling direction under the control of the control unit corresponding to the result identified by the barcode reader. With this configuration, a multi-shape and multiple amount of electrical parts are distributed to a large number of shooters at high speed.

　しかしながら、特許文献１に記載の仕分け装置では、多数のシュータを仕分け用コンベアの両側に配置する必要があると共に、仕分け用コンベアに加えて、当該仕分け用コンベアの搬送方向と直角の方向に移動可能なベルトを備える必要があることから、装置の構成及び仕分けに関する制御が複雑となってしまう。 However, in the sorting apparatus described in Patent Document 1, it is necessary to arrange a large number of shooters on both sides of the sorting conveyor, and in addition to the sorting conveyor, the sorting apparatus can move in a direction perpendicular to the conveying direction of the sorting conveyor. Since it is necessary to provide a simple belt, the control relating to the configuration and sorting of the apparatus becomes complicated.

　以下、本発明に係る搬送物選別装置の一実施形態について、図面に基づいて詳細に説明する。 Hereinafter, an embodiment of a conveyed product sorting apparatus according to the present invention will be described in detail with reference to the drawings.
　図１～図３に示すように、本実施形態の搬送物選別装置１は、スライドファスナーに用いられる複数の種類の引手（搬送物）３を収容し、一個ずつ排出することが可能なパーツフィーダー５と、パーツフィーダー５から供給された引手３を下流側に搬送する搬送コンベアと、その上流側端部が搬送コンベアの下流側端部と接続され、且つその下流側端部がパーツフィーダー５と接続される復路コンベア４０と、を備える。搬送コンベアは、搬送方向に沿って配置された複数のコンベア１０、２０、３０で構成されている。本実施形態において、搬送コンベアは、供給コンベア１０と、その上流側端部が供給コンベア１０の下流側端部と接続される上流側コンベア２０と、その上流側端部が上流側コンベア２０の下流側端部と接続される下流側コンベア３０と、を備える。 As shown in FIGS. 1 to 3, the conveyed product sorting apparatus 1 according to the present embodiment accommodates a plurality of types of pullers (conveyed items) 3 used for slide fasteners, and can be discharged one by one. 5, a transport conveyor that transports the handle 3 supplied from the parts feeder 5 to the downstream side, an upstream end thereof is connected to a downstream end of the transport conveyor, and a downstream end thereof is connected to the parts feeder 5. And a return conveyor 40 to be connected. The conveyor is composed of a plurality of conveyors 10, 20, 30 arranged along the conveyance direction. In the present embodiment, the transport conveyor includes a supply conveyor 10, an upstream conveyor 20 whose upstream end is connected to a downstream end of the supply conveyor 10, and an upstream end thereof downstream of the upstream conveyor 20. A downstream conveyor 30 connected to the side end.
　パーツフィーダー５は、複数の種類の引手３が投入される投入口６と、投入された引手３を次工程に搬送する螺旋状のトラック７と、トラック７に振動を加える加振体８と、を有する。トラック７は、供給コンベア１０の上流側端部にスロープ９を介して接続しており、加振体８の振動によって引手３を供給コンベア１０側に搬送する。なお、引手３は、その厚み方向がトラック７の上面と垂直となるように搬送される。以下の工程においても、引手３は、その厚み方向が供給コンベア１０、上流側コンベア２０、下流側コンベア３０、及び復路コンベア４０の上面と垂直となるように搬送される。 The parts feeder 5 includes an insertion port 6 into which a plurality of types of pullers 3 are inserted, a spiral track 7 that conveys the loaded pullers 3 to the next process, and a vibrating body 8 that applies vibration to the tracks 7. Have The track 7 is connected to the upstream end portion of the supply conveyor 10 via a slope 9, and conveys the handle 3 to the supply conveyor 10 side by the vibration of the vibrating body 8. The puller 3 is conveyed so that its thickness direction is perpendicular to the upper surface of the track 7. Also in the following steps, the puller 3 is transported so that the thickness direction thereof is perpendicular to the upper surfaces of the supply conveyor 10, the upstream conveyor 20, the downstream conveyor 30, and the return conveyor 40.
　供給コンベア１０は、搬送物選別装置１が設置される床面に対して水平に延在しており、不図示の駆動モータによって駆動されることにより、その上面で引手３を下流側に搬送する。また、供給コンベア１０の上方には、引手３の厚み以下の僅かな隙間を空けて第一ガイド部材１１が配置されており、供給コンベア１０上の引手３は第一ガイド部材１１の側面１１ａに沿って案内される。 The supply conveyor 10 extends horizontally with respect to the floor surface on which the conveyed product sorting apparatus 1 is installed, and is driven by a drive motor (not shown) to convey the handle 3 on the upper surface thereof to the downstream side. . Further, the first guide member 11 is disposed above the supply conveyor 10 with a slight gap below the thickness of the pull handle 3, and the pull handle 3 on the supply conveyor 10 is placed on the side surface 11 a of the first guide member 11. Will be guided along.
　また、第一ガイド部材１１は、下流側に向かうにしたがって供給コンベア１０の幅方向一方側（復路コンベア４０側）に変位している。これにより、第一ガイド部材１１の側面１１ａと供給コンベア１０の幅方向一方側端部１２との幅方向距離は、下流側に向かうにしたがって小さくなる。そして、第一ガイド部材１１の側面１１ａと供給コンベア１０の幅方向一方側端部１２との幅方向距離は、第一ガイド部材１１の下流側端部と搬送方向で重なる位置において、引手３の一個分の幅と略等しくなるように設定される。これにより、供給コンベア１０は、第一ガイド部材１１の下流側端部と搬送方向で重なる位置において、幅方向に複数の引手３が並ぶことを防止し、一個の引手３のみ搬送する。そして、供給コンベア１０は、複数の引手３を、搬送方向に並んだ状態で上流側コンベア２０に供給することが可能となる。 Moreover, the 1st guide member 11 is displaced to the width direction one side (return conveyor 40 side) of the supply conveyor 10 as it goes downstream. Thereby, the width direction distance of the side surface 11a of the 1st guide member 11 and the width direction one side edge part 12 of the supply conveyor 10 becomes small as it goes downstream. And the width direction distance of the side surface 11a of the 1st guide member 11 and the width direction one side edge part 12 of the supply conveyor 10 is the position of the handle 3 in the position which overlaps with the downstream edge part of the 1st guide member 11, and a conveyance direction. It is set to be approximately equal to the width of one piece. Thereby, the supply conveyor 10 prevents the plurality of pullers 3 from being arranged in the width direction at a position overlapping the downstream end portion of the first guide member 11 in the transport direction, and transports only one puller 3. Then, the supply conveyor 10 can supply the plurality of pullers 3 to the upstream conveyor 20 in a state of being arranged in the transport direction.
　ここで、供給コンベア１０は、第一ガイド部材１１の下流側端部と搬送方向で重なる位置において、幅方向に複数の引手３が並んだ場合に、供給コンベア１０の幅方向一方側に引手３を落下させてしまう。しかしながら、本実施形態では、復路コンベア４０が、供給コンベア１０の幅方向一方側に隣接して配置されている。そして、供給コンベア１０は、図４に示すように、第一ガイド部材１１の下流側端部と搬送方向で重なる位置において、復路コンベア４０よりも上方に位置する。したがって、供給コンベア１０から落下した引手３は復路コンベア４０によって支持される。そして、引手３は、復路コンベア４０によって、パーツフィーダー５を介して再び供給コンベア１０の上流側端部に戻され、再び供給コンベア１０によって下流側へ搬送されることが可能となる。 Here, the supply conveyor 10 has a puller 3 on one side in the width direction of the supply conveyor 10 when a plurality of pullers 3 are arranged in the width direction at a position overlapping the downstream end of the first guide member 11 in the transport direction. Will fall. However, in this embodiment, the return conveyor 40 is disposed adjacent to one side in the width direction of the supply conveyor 10. Then, as shown in FIG. 4, the supply conveyor 10 is positioned above the return conveyor 40 at a position overlapping the downstream end of the first guide member 11 in the transport direction. Therefore, the handle 3 dropped from the supply conveyor 10 is supported by the return path conveyor 40. Then, the pull handle 3 is returned to the upstream end of the supply conveyor 10 again by the return path conveyor 40 via the parts feeder 5 and can be conveyed downstream by the supply conveyor 10 again.
　また、図４に示すように、複数の第一エア噴射孔１３が、第一ガイド部材１１の側面１１ａに形成されている。それぞれの第一エア噴射孔１３は、第一ガイド部材１１の長さ方向に所定の間隔を空けて形成されている。本実施形態によれば、第一エア噴射孔１３は６個形成されている。それぞれの第一エア噴射孔１３は、供給コンベア１０の幅方向一方側に向かってエアを噴射する。それぞれの第一エア噴射孔１３は、第一ガイド部材１１の上部に設けられたエア供給ノズル１４と、第一ガイド部材１１の内部で接続されている。エア供給ノズル１４は、図示せぬエア供給源と接続されている。エア供給ノズル１４から供給された空気が第一エア噴射孔１３から噴射される。 Further, as shown in FIG. 4, a plurality of first air injection holes 13 are formed in the side surface 11 a of the first guide member 11. The first air injection holes 13 are formed at predetermined intervals in the length direction of the first guide member 11. According to this embodiment, six first air injection holes 13 are formed. Each first air injection hole 13 injects air toward one side in the width direction of the supply conveyor 10. Each of the first air injection holes 13 is connected to an air supply nozzle 14 provided in the upper part of the first guide member 11 inside the first guide member 11. The air supply nozzle 14 is connected to an air supply source (not shown). Air supplied from the air supply nozzle 14 is injected from the first air injection hole 13.
　ここで、図７に示すように、それぞれの第一エア噴射孔１３は、供給コンベア１０の上面からの上下方向距離が異なっている。それぞれの第一エア噴射孔１３は、供給される引手３の種類によって、何れの第一エア噴射孔１３からエアを噴射させるか選択される。すなわち、供給コンベア１０の上面から第一エア噴射孔１３までの上下方向距離が、引手３の厚さの１倍より大きく２倍以下となるような第一エア噴射孔１３を選択する。これにより、エア供給源は、選択された第一エア噴射孔１３からエアを噴射させるように、エア供給ノズル１４にエアを供給する。 Here, as shown in FIG. 7, the first air injection holes 13 have different vertical distances from the upper surface of the supply conveyor 10. Each of the first air injection holes 13 is selected from which first air injection hole 13 to inject air depending on the type of the handle 3 to be supplied. That is, the first air injection hole 13 is selected such that the distance in the vertical direction from the upper surface of the supply conveyor 10 to the first air injection hole 13 is greater than 1 and less than or equal to 2 times the thickness of the handle 3. Thereby, the air supply source supplies air to the air supply nozzle 14 so that the air is injected from the selected first air injection hole 13.
　このように、適切な第一エア噴射孔１３を選択することによって、複数の引手３が上下方向に重なってしまった場合に、最も下方に位置する（供給コンベア１０の上面に当接する）引手３はそのまま第一ガイド部材１１の側面１１ａによって案内され、上方に重なった引手３のみをエアで取り除くことができる。すなわち、第一エア噴射孔１３は、複数の引手３が上下方向に重なることを防止する。これにより、供給コンベア１０は、引手３を一つずつ上流側コンベア２０に供給することが可能である。 In this way, by selecting an appropriate first air injection hole 13, when the plurality of pullers 3 overlap in the vertical direction, the puller 3 that is positioned at the lowest position (abuts against the upper surface of the supply conveyor 10). Is guided as it is by the side surface 11a of the first guide member 11, and only the handle 3 that overlaps the upper side can be removed with air. That is, the first air injection holes 13 prevent the plurality of pullers 3 from overlapping in the vertical direction. Thereby, the supply conveyor 10 can supply the handle 3 to the upstream conveyor 20 one by one.
　以上のように、第一ガイド部材１１によって搬送方向と直交する方向（幅方向）における重なりが防止され、第一エア噴射孔１３によって上下方向における重なりが防止された引手３は、続いて、第三ガイド部材１５に沿って下流側に案内される。第三ガイド部材１５は、供給コンベア１０の上方に引手３の厚み以下の僅かな隙間を空けて配置されると共に、下流側に向かうにしたがって供給コンベア１０の幅方向他方側に変位しており、引手３を供給コンベア１０の幅方向中間部へ案内する。 As described above, the first guide member 11 prevents the overlap in the direction (width direction) orthogonal to the transport direction, and the first air injection hole 13 prevents the overlap in the vertical direction, Guided downstream along the three guide members 15. The third guide member 15 is disposed above the supply conveyor 10 with a slight gap below the thickness of the handle 3 and is displaced to the other side in the width direction of the supply conveyor 10 toward the downstream side. The handle 3 is guided to the intermediate portion in the width direction of the supply conveyor 10.
　供給コンベア１０の下流側端部にはスロープ１６が配置されている。スロープ１６は、上流側コンベア２０の上面に向けて下り傾斜している。引手３は、供給コンベア１０の幅方向中間部から、スロープ１６を滑り落ちて、上流側コンベア２０に供給される。 A slope 16 is arranged at the downstream end of the supply conveyor 10. The slope 16 is inclined downward toward the upper surface of the upstream conveyor 20. The puller 3 slides down the slope 16 from the intermediate portion in the width direction of the supply conveyor 10 and is supplied to the upstream conveyor 20.
　上流側コンベア２０は、床面に対して水平に延在しており、駆動モータ２１によって駆動されることにより、その上面で引手３を下流側に搬送する。また、上流側コンベア２０の下流部には、図５に示すように、引手３の通過を検知する通過センサ２２が設けられる。通過センサ２２で検知された引手３は、後述する条件を満たした場合には、引き続き上流側コンベア２０によって下流側に搬送され、上流側コンベア２０から下流側コンベア３０に供給される。 The upstream conveyor 20 extends horizontally with respect to the floor surface, and is driven by a drive motor 21 to convey the handle 3 to the downstream side on its upper surface. Further, as shown in FIG. 5, a passage sensor 22 that detects passage of the handle 3 is provided in the downstream portion of the upstream conveyor 20. The pulling hand 3 detected by the passage sensor 22 is continuously conveyed downstream by the upstream conveyor 20 and supplied from the upstream conveyor 20 to the downstream conveyor 30 when conditions described later are satisfied.
　下流側コンベア３０は、駆動モータ３１によって駆動されることにより、その上面で引手３を下流側に搬送する。ここで、引手３の搬送距離を測定する測定装置３２が、下流側コンベアに設けられている。測定装置３２は、下流側コンベア３０の復路コンベア４０側の下流側端部に配置されたエンコーダを有する。エンコーダは、下流側コンベア３０の搬送速度を測定する。 The downstream conveyor 30 is driven by the drive motor 31 to convey the handle 3 to the downstream side on the upper surface thereof. Here, a measuring device 32 for measuring the conveyance distance of the pull handle 3 is provided on the downstream conveyor. The measuring device 32 has an encoder arranged at the downstream end of the downstream conveyor 30 on the return conveyor 40 side. The encoder measures the conveyance speed of the downstream conveyor 30.
　ここで、図３に示すように、連続して搬送される２つの引手３のうち、上流側に位置する引手３を上流側引手３Ａとし、下流側に位置する引手３を下流側引手３Ｂとする。測定装置３２は、通過センサ２２が下流側引手３Ｂの通過を検知した時から、通過センサ２２が上流側引手３Ａの通過を検知した時までの下流側引手３Ｂの搬送距離Ｌを測定する。本実施形態によれば、通過センサ２２が下流側引手３Ｂの通過を検知した時、エンコーダが下流側コンベア３０の搬送速度を測定する。測定装置３２は下流側コンベア３０の搬送速度に基づいて、下流側引手３Ｂの搬送距離Ｌの測定を開始する。そして、測定装置３２は、通過センサ２２が上流側引手３Ａの通過を検知した時、下流側引手３Ｂの搬送距離Ｌの測定を終了する。この時、駆動モータ２１は、搬送距離Ｌが所定値Ａ以上である場合、上流側コンベア２０を連続運転して上流側引手３Ａを下流に搬送する。また、駆動モータ２１は、搬送距離Ｌが所定値Ａ未満である場合、搬送距離Ｌが所定値Ａ以上になるまで上流側コンベア２０の運転を停止する。 Here, as shown in FIG. 3, of the two pullers 3 that are continuously conveyed, the puller 3 positioned on the upstream side is referred to as an upstream puller 3 </ b> A, and the puller 3 positioned on the downstream side is referred to as a downstream puller 3 </ b> B. To do. The measuring device 32 measures the conveyance distance L of the downstream handle 3B from the time when the passage sensor 22 detects the passage of the downstream handle 3B to the time when the passage sensor 22 detects the passage of the upstream handle 3A. According to this embodiment, when the passage sensor 22 detects the passage of the downstream handle 3 </ b> B, the encoder measures the conveyance speed of the downstream conveyor 30. The measuring device 32 starts measuring the transport distance L of the downstream handle 3 </ b> B based on the transport speed of the downstream conveyor 30. And the measuring apparatus 32 complete | finishes the measurement of the conveyance distance L of the downstream handle 3B, when the passage sensor 22 detects passage of the upstream handle 3A. At this time, when the transport distance L is equal to or greater than the predetermined value A, the drive motor 21 continuously operates the upstream conveyor 20 to transport the upstream puller 3A downstream. Further, when the transport distance L is less than the predetermined value A, the drive motor 21 stops the operation of the upstream conveyor 20 until the transport distance L becomes equal to or greater than the predetermined value A.
　このように、上流側コンベア２０は、間欠運転することにより、下流側コンベア３０上における下流側引手３Ｂと上流側引手３Ａとの距離を所定値Ａ以上に維持することができる。これにより、複数の引手３は、互いの距離が常に所定値Ａ以上となり、種類毎に選別する際の識別が容易になる。また、複数の引手３は、後述するシュータ３４で排出される際、一つずつ確実に排出されることができる。 Thus, the upstream conveyor 20 can maintain the distance between the downstream handle 3B and the upstream handle 3A on the downstream conveyor 30 at a predetermined value A or more by performing intermittent operation. Thereby, the distance between the plurality of pullers 3 is always equal to or greater than the predetermined value A, and identification when sorting by type is facilitated. Further, the plurality of pullers 3 can be reliably discharged one by one when discharged by a shooter 34 described later.
　ここで、本実施形態における所定値Ａは、後術するシャッタ３５の搬送方向の幅より大きく設定される。また、所定値Ａは、下流側コンベア３０の搬送速度とシャッタ３５の開閉に要する時間とに基づいて設定される。すなわち、所定値Ａは、シャッタ３５が開状態から閉状態になるまでに、引手３がシャッタ３５に接する位置に搬送されないように設定される。これにより、異なる種類の引手３が同じシュータ３４に排出されることを防止する効果を奏する。 Here, the predetermined value A in the present embodiment is set to be larger than the width in the transport direction of the shutter 35 to be operated later. The predetermined value A is set based on the conveyance speed of the downstream conveyor 30 and the time required to open and close the shutter 35. That is, the predetermined value A is set so that the handle 3 is not conveyed to a position in contact with the shutter 35 until the shutter 35 is changed from the open state to the closed state. Thereby, there exists an effect which prevents that the pull handle 3 of a different kind is discharged | emitted by the same shooter 34. FIG.
　また、上流側コンベア２０の搬送速度は、供給コンベア１０の搬送速度よりも速く設定されている。これにより、上流側コンベア２０上の複数の引手３の距離を、供給コンベア１０上の複数の引手３の距離に比べて離間することができる。そして、上流側コンベア２０は、予め複数の引手３の距離を離間させた状態で、下流側コンベア３０に引手３を一つずつ供給するので、下流側コンベア３０上における複数の引手３の距離を、所定値Ａ以上に維持することが容易となる。 Further, the transport speed of the upstream conveyor 20 is set to be faster than the transport speed of the supply conveyor 10. Thereby, the distance of the several handle 3 on the upstream conveyor 20 can be separated compared with the distance of the several handle 3 on the supply conveyor 10. FIG. And since the upstream conveyor 20 supplies the handle 3 to the downstream conveyor 30 one by one in the state where the distance of the plurality of pullers 3 was previously separated, the distance of the plurality of pullers 3 on the downstream conveyor 30 is set. It becomes easy to maintain the predetermined value A or more.
　さらに、下流側コンベア３０の搬送速度は、上流側コンベア２０の搬送速度よりも速く設定されている。これにより、下流側コンベア３０上は、下流側コンベア３０上の複数の引手３の距離を、所定値Ａ以上に維持することがより容易となる。 Furthermore, the conveyance speed of the downstream conveyor 30 is set faster than the conveyance speed of the upstream conveyor 20. Thereby, it becomes easier on the downstream conveyor 30 to maintain the distance between the plurality of pullers 3 on the downstream conveyor 30 at a predetermined value A or more.
　下流側コンベア３０は、供給コンベア１０や上流側コンベア２０と異なり、床面と水平な方向に対して、幅方向他方側が幅方向一方側よりも下方となるように下り傾斜している。すなわち、下流側コンベア３０は、後述するシュータ３４側へ下り傾斜している。したがって、引手３は、下流側コンベア３０によって搬送される時、その自重によって幅方向他方側に変位する。引手３の脱落を防ぐ壁部材３３が下流側コンベア３０の幅方向他方側に設けられている。壁部材３３は、図５に示すように、下流側コンベア３０の上面よりも上方に向けて突出している。引手３は壁部材３３に沿って案内される。 Unlike the supply conveyor 10 and the upstream conveyor 20, the downstream conveyor 30 is inclined downward so that the other side in the width direction is lower than the one side in the width direction with respect to the horizontal direction with respect to the floor surface. That is, the downstream conveyor 30 is inclined downward toward the shooter 34 described later. Therefore, when the handle 3 is conveyed by the downstream conveyor 30, it is displaced to the other side in the width direction by its own weight. A wall member 33 that prevents the puller 3 from falling off is provided on the other side in the width direction of the downstream conveyor 30. As shown in FIG. 5, the wall member 33 protrudes upward from the upper surface of the downstream conveyor 30. The handle 3 is guided along the wall member 33.
　上流側コンベア２０の下流側端部にはスロープ２３が配置されている。スロープ２３は、下流側コンベア３０の上面に向けて下り傾斜している。引手３は、上流側コンベア２０の幅方向中間部から、スロープ２３を滑り落ちて、下流側コンベア３０に供給される。 A slope 23 is arranged at the downstream end of the upstream conveyor 20. The slope 23 is inclined downward toward the upper surface of the downstream conveyor 30. The puller 3 slides down the slope 23 from the intermediate portion in the width direction of the upstream conveyor 20 and is supplied to the downstream conveyor 30.
　図５に示すように、スロープ２３は、幅方向に離間して配置された幅方向一方側壁部２３ｂと、幅方向他方側壁部２３ａを有する。幅方向他方側壁部２３ａは、下流側コンベア３０の壁部材３３寄りに配置されると共に、壁部材３３と略平行となるように配置される。一方、幅方向一方側壁部２３ｂは、下流側に向かうにしたがって幅方向他方側壁部２３ａに近づくように傾斜して配置される。したがって、引手３は、幅方向他方側壁部２３ａ及び幅方向一方側壁部２３ｂによって、下流側コンベア３０の壁部材３３の近傍まで案内される。これにより、引手３は、厚み方向が下流側コンベア３０と垂直な状態のまま、下流側コンベア３０に供給される。すなわち、引手３は、下流側コンベア３０上で、引手３の上面又は下面が壁部材３３に支持されることを防止できる。 As shown in FIG. 5, the slope 23 includes a width direction one side wall portion 23 b and a width direction other side wall portion 23 a which are arranged apart from each other in the width direction. The other side wall portion 23 a in the width direction is disposed near the wall member 33 of the downstream conveyor 30 and is disposed so as to be substantially parallel to the wall member 33. On the other hand, the width direction one side wall part 23b is inclined and arranged so as to approach the width direction other side wall part 23a toward the downstream side. Therefore, the handle 3 is guided to the vicinity of the wall member 33 of the downstream conveyor 30 by the other side wall portion 23a in the width direction and the one side wall portion 23b in the width direction. Thereby, the handle 3 is supplied to the downstream conveyor 30 with the thickness direction being perpendicular to the downstream conveyor 30. That is, the handle 3 can prevent the upper surface or the lower surface of the handle 3 from being supported by the wall member 33 on the downstream conveyor 30.
　また、シュータ３４が下流側コンベア３０の幅方向他方側に設けられている。シュータ３４は、下流側コンベア３０の搬送方向に所定の間隔を空けて複数配置されている。それぞれのシュータ３４は、同種類の引手３のみを下流側コンベア３０から排出する。本実施形態では、四つのシュータ３４が設けられ、上流側から１個目及び３個目のシュータ３４の形状を等しくし、２個目及び４個目のシュータ３４の形状を等しくしている。これにより、それぞれのシュータ３４の排出口３４ａから排出される引手３を収容するための容器の配置場所を確保することができる。なお、これらのシュータ３４の形状は特に限定されるものではない。また、それぞれのシュータ３４には、外部から引手３の排出状態が視認できるように、覗き窓３４ｂを設けるとよい。 Also, a shooter 34 is provided on the other side in the width direction of the downstream conveyor 30. A plurality of the shooters 34 are arranged at a predetermined interval in the conveyance direction of the downstream conveyor 30. Each shooter 34 discharges only the same type of handle 3 from the downstream conveyor 30. In the present embodiment, four shooters 34 are provided, and the first and third shooters 34 from the upstream side have the same shape, and the second and fourth shooters 34 have the same shape. Thereby, the arrangement | positioning location of the container for accommodating the handle 3 discharged | emitted from the discharge port 34a of each shooter 34 is securable. In addition, the shape of these shooters 34 is not specifically limited. Each shooter 34 is preferably provided with a viewing window 34b so that the discharge state of the handle 3 can be visually recognized from the outside.
　シャッタ３５が、それぞれのシュータ３４と下流側コンベア３０の間に配置されている。シャッタ３５は、上下方向に変位可能であり、閉状態（下方に位置する状態）において、引手３がシュータ３４へ排出されることを防止する。また、シャッタ３５は、開状態（上方に位置する状態）において、引手３がシュータ３４から排出されることを許容する。なお、壁部材３３は、シャッタ３５が配置される位置に配置されていない。 A shutter 35 is disposed between each shooter 34 and the downstream conveyor 30. The shutter 35 can be displaced in the vertical direction, and prevents the handle 3 from being discharged to the shooter 34 in the closed state (a state positioned below). Further, the shutter 35 allows the handle 3 to be discharged from the shooter 34 in the open state (a state positioned above). The wall member 33 is not disposed at a position where the shutter 35 is disposed.
　引手３が通過したことを検知するセンサ３６が、図３に示すように、それぞれのシュータ３４よりも下流側コンベア３０の上流側に配置される。センサ３６は、光電センサや近接センサのごとき、非接触センサであることが好ましい。また、引手３の種類を判別する判別装置３７が、図６に示すように、それぞれのシュータ３４よりも下流側コンベア３０の上流側に配置される。判別装置３７は、センサ３６の上方に配置され、フレーム３８に取付けられた光源３７ａ及び画像検査装置３７ｂを有する。画像検査装置３７ｂは、引手３を撮影するカメラや、当該カメラによって撮影された引手３の画像を解析する解析装置を有しており、画像解析結果に基づいて引手３の種類を判別することが可能である。光源３７ａは、画像検査装置３７ｂによる画像解析が確実となるように、引手３の周辺に十分な照度を与える。 As shown in FIG. 3, a sensor 36 that detects that the puller 3 has passed is disposed on the upstream side of the downstream conveyor 30 with respect to each shooter 34. The sensor 36 is preferably a non-contact sensor such as a photoelectric sensor or a proximity sensor. Further, as shown in FIG. 6, a discriminating device 37 that discriminates the type of the pull handle 3 is arranged on the upstream side of the downstream conveyor 30 with respect to each shooter 34. The discrimination device 37 includes a light source 37 a and an image inspection device 37 b that are disposed above the sensor 36 and attached to the frame 38. The image inspection device 37b has a camera that captures the handle 3 and an analysis device that analyzes the image of the handle 3 captured by the camera, and can determine the type of the handle 3 based on the image analysis result. Is possible. The light source 37a gives sufficient illuminance to the periphery of the handle 3 so that the image analysis by the image inspection device 37b is ensured.
　それぞれの判別装置３７は、センサ３６による引手３の通過の感知を受けて、引手３の種類を判別する。そして、それぞれの判別装置３７は、引手３が所定の種類である場合に、シャッタ３５を開状態として、引手３をシュータ３４に排出する。また、それぞれの判別装置３７は、引手３が所定の種類以外である場合には、シャッタ３５を閉状態として、引手３を下流側コンベア３０の下流側に搬送する。 Each discriminating device 37 discriminates the type of the puller 3 upon receiving the passage of the puller 3 by the sensor 36. Each discriminating device 37 opens the shutter 35 and discharges the handle 3 to the shooter 34 when the handle 3 is of a predetermined type. In addition, each determination device 37 transports the handle 3 to the downstream side of the downstream conveyor 30 with the shutter 35 closed when the handle 3 is of a type other than the predetermined type.
　したがって、それぞれのシュータ３４は、同種類の引手３のみを排出することになり、引手３を選別することが可能となる。このとき、下流側コンベア３０は、シュータ３４側が下方となるように傾斜しているので、下流側コンベア３０を搬送される引手３が、引手３の自重によってシュータ３４側に位置している。これにより、引手３は、シャッタ３５を開状態とした場合、引手３の自重を利用した簡易な構成によって、シュータ３４に確実に排出される。また、引手３は、シャッタ３５が閉状態の場合、壁部材３３及びシャッタ３５に沿って案内されながら、シュータ３４側近傍を搬送される。これにより、引手３は、シャッタ３５を開状態とした場合、即座にシュータ３４に排出することができる。 Therefore, each shooter 34 discharges only the same type of puller 3, and the puller 3 can be selected. At this time, since the downstream conveyor 30 is inclined so that the shooter 34 side is downward, the puller 3 conveyed on the downstream conveyor 30 is positioned on the shooter 34 side by the weight of the puller 3. Thereby, when the shutter 35 is in the open state, the puller 3 is reliably discharged to the shooter 34 with a simple configuration using the weight of the puller 3. Further, when the shutter 35 is in the closed state, the handle 3 is conveyed in the vicinity of the shooter 34 while being guided along the wall member 33 and the shutter 35. Thereby, the handle 3 can be immediately discharged to the shooter 34 when the shutter 35 is opened.
　また、上述したように、引手３は、その厚み方向が下流側コンベア３０と垂直となるように、下流側コンベア３０に搬送されるので、引手３をシュータ３４に排出する際に、シャッタ３５を引手３の厚み分だけ開閉動作をすればよく、シャッタ３５の動作を少なくすることが可能である。また、引手３の外形や、引手３に設けられたロゴ等が、判別装置３７によって認識され易くなるため、引手３の種類を確実に判別することが可能である。 Further, as described above, the handle 3 is transported to the downstream conveyor 30 so that the thickness direction thereof is perpendicular to the downstream conveyor 30, and therefore, when the handle 3 is discharged to the shooter 34, the shutter 35 is moved. The opening / closing operation may be performed by the thickness of the handle 3, and the operation of the shutter 35 can be reduced. Further, since the outer shape of the pull handle 3, a logo provided on the pull handle 3, and the like are easily recognized by the determination device 37, it is possible to reliably determine the type of the pull handle 3.
　また、下流側コンベア３０には、シュータ３４と対向する側（幅方向一方側）に、エアブロー手段３９が配置される。エアブロー手段３９は、下流側コンベア３０によって搬送される引手３に圧縮空気を吹き付けることにより、引手３をシュータ３４側に位置させる。エアブロー手段３９は、判別装置３７が引手３の種類を判別し、引手３が所定の種類である場合に、引手３に圧縮空気を吹き付ける。この時、判別装置３７はシャッタ３５を開状態とする。これにより、引手３は、圧縮空気によってシュータ３４へ向けて押され、シュータ３４に排出される。一方、エアブロー手段３９は、判別装置３７が引手３の種類を判別し、引手３が所定の種類以外である場合に、引手３に圧縮空気を吹き付けない。この時、判別装置３７はシャッタ３５を閉状態とする。これにより、引手３は、シュータ３４に排出されず、下流側コンベア３０の下流側に搬送される。 In the downstream conveyor 30, air blow means 39 is disposed on the side facing the shooter 34 (one side in the width direction). The air blow means 39 positions the handle 3 on the shooter 34 side by blowing compressed air onto the handle 3 conveyed by the downstream conveyor 30. The air blower 39 discriminates the type of the handle 3 by the discriminating device 37, and blows compressed air to the handle 3 when the handle 3 is a predetermined type. At this time, the determination device 37 opens the shutter 35. As a result, the puller 3 is pushed toward the shooter 34 by the compressed air and discharged to the shooter 34. On the other hand, the air blow means 39 does not blow compressed air on the puller 3 when the determination device 37 determines the type of the puller 3 and the puller 3 is other than a predetermined type. At this time, the determination device 37 closes the shutter 35. Thereby, the handle 3 is not discharged to the shooter 34 but is conveyed to the downstream side of the downstream conveyor 30.
　このように、引手３は、引手３の自重に加えて、エアブロー手段３９によって圧縮空気が吹き付けられることにより、より確実に排出されることができる。 Thus, the puller 3 can be discharged more reliably by the compressed air being blown by the air blow means 39 in addition to its own weight.
　なお、例外として、引手３は、判別装置３７によって種類が判別できない場合や、複数の引手３の距離が所定値Ａ未満である場合には、何れのシュータ３４にも排出されず、下流側コンベア３０の下流側端部に搬送されることになる。この理由は、異なる種類の引手３が同一のシュータ３４に排出されてしまう虞があるからである。 As an exception, when the type of the puller 3 cannot be determined by the determination device 37 or when the distance between the plurality of pullers 3 is less than the predetermined value A, the puller 3 is not discharged to any of the shooters 34, and the downstream conveyor 30 to the downstream end. This is because different types of pullers 3 may be discharged to the same shooter 34.
　下流側コンベア３０の下流側端部にはスロープ４１が配置されている。スロープ４１は、復路コンベア４０の上面に向けて下り傾斜している。引手３は、下流側コンベア３０から、スロープ４１を滑り落ちて、復路コンベア４０に供給される。下流側コンベア３０において選別することができなかった引手３は、復路コンベア４０によって搬送されることになる。 A slope 41 is arranged at the downstream end of the downstream conveyor 30. The slope 41 is inclined downward toward the upper surface of the return path conveyor 40. The puller 3 slides down the slope 41 from the downstream conveyor 30 and is supplied to the return conveyor 40. The handle 3 that could not be sorted in the downstream conveyor 30 is conveyed by the return conveyor 40.
　復路コンベア４０は、不図示の駆動モータにより駆動されており、供給コンベア１０、上流側コンベア２０、及び下流側コンベア３０の幅方向一方側に隣接して延在している。また、復路コンベア４０は、上流側から下流側に向かうにしたがって、上方に向かって傾斜している。そして、復路コンベア４０は、図４に示すように、第一ガイド部材１１の下流側端部と搬送方向で重なる位置において、供給コンベア１０よりも下方に位置する。 The return conveyor 40 is driven by a drive motor (not shown) and extends adjacent to one side in the width direction of the supply conveyor 10, the upstream conveyor 20, and the downstream conveyor 30. The return conveyor 40 is inclined upward as it goes from the upstream side to the downstream side. Then, as shown in FIG. 4, the return conveyor 40 is positioned below the supply conveyor 10 at a position overlapping the downstream end of the first guide member 11 in the transport direction.
　また、復路コンベア４０の下流部の上方、より具体的には、第一ガイド部材１１と搬送方向で重なる位置の上方には、第二ガイド部材４２が配置される。第二ガイド部材４２は、駆動機構４３によって上下方向に変位可能であり、閉状態（下方に位置する状態）で引手３をその側面４２ａに沿って案内し、開状態（上方に位置する状態）で引手３の下流側への搬送を許容する。 Further, the second guide member 42 is disposed above the downstream portion of the return path conveyor 40, more specifically, above the position overlapping the first guide member 11 in the transport direction. The second guide member 42 can be displaced in the vertical direction by the drive mechanism 43, guides the handle 3 along the side surface 42a in the closed state (a state positioned below), and the open state (a state positioned above). Thus, the conveyance of the puller 3 to the downstream side is allowed.
　第二ガイド部材４２は、第一ガイド部材１１と略平行となるように配置され、復路コンベア４０の下流側に向かうにしたがって、復路コンベア４０の幅方向他方側に変位して、復路コンベア４０の幅方向他方側端部４４まで延在する。そして、復路コンベア４０は、第二ガイド部材４２の下流側端部と搬送方向で重なる位置において、供給コンベア１０よりも上方に位置する。 The second guide member 42 is disposed so as to be substantially parallel to the first guide member 11, and is displaced toward the other side in the width direction of the return conveyor 40 toward the downstream side of the return conveyor 40. It extends to the other end 44 in the width direction. The return conveyor 40 is located above the supply conveyor 10 at a position overlapping the downstream end of the second guide member 42 in the transport direction.
　したがって、復路コンベア４０で搬送される引手３は、第二ガイド部材４２を閉状態とすることにより、第二ガイド部材４２の側面４２ａに案内されて、供給コンベア１０に戻ることができる。これにより、復路コンベア４０は、供給コンベア１０上の引手３が不足した場合に、供給コンベア１０へ引手３を速やかに供給することが可能となる。 Therefore, the handle 3 conveyed by the return conveyor 40 can be guided to the side surface 42a of the second guide member 42 and returned to the supply conveyor 10 by closing the second guide member 42. As a result, the return conveyor 40 can quickly supply the handle 3 to the supply conveyor 10 when the handle 3 on the supply conveyor 10 is insufficient.
　また、エア供給手段４５が、復路コンベア４０の第二ガイド部材４２よりも上流側に配置される。エア供給手段４５は、復路コンベア４０の上方に配置されると共に、復路コンベア４０の幅方向に延びている。エア供給手段４５は、図８に示すように、複数の第二エア噴射孔４７を有する。それぞれの第二エア噴射孔４７は、エア供給手段４５の長さ方向に所定の間隔を空けて配置されている。それぞれの第二エア噴射孔４７は、当該第二エア噴射孔４７からエアを上流側の引手３に向かって吹き付ける（図８中の矢印を参照。）。これにより、引手３の下流側への移動を規制することが可能である。したがって、エア供給手段４５は、第二ガイド部材４２が開状態から閉状態に変わる前に、予め引手３の下流側への移動を規制することにより、閉状態となった第二ガイド部材４２と復路コンベア４０の上面との間に引手３が挟まれてしまうことを防止できる。 Further, the air supply means 45 is arranged on the upstream side of the second guide member 42 of the return conveyor 40. The air supply means 45 is disposed above the return conveyor 40 and extends in the width direction of the return conveyor 40. The air supply means 45 has a plurality of second air injection holes 47 as shown in FIG. Each of the second air injection holes 47 is arranged at a predetermined interval in the length direction of the air supply means 45. Each second air injection hole 47 blows air from the second air injection hole 47 toward the handle 3 on the upstream side (see the arrow in FIG. 8). Thereby, it is possible to regulate the movement of the handle 3 to the downstream side. Therefore, the air supply means 45 is configured so that the second guide member 42 in the closed state is controlled by restricting the movement of the handle 3 to the downstream side in advance before the second guide member 42 is changed from the open state to the closed state. It is possible to prevent the handle 3 from being sandwiched between the upper surface of the return conveyor 40.
　そして、引手３は、第二ガイド部材４２が開状態である場合に、第二ガイド部材４２よりも下流側に設けられた第四ガイド部材４６によって下流側端部に案内されて、パーツフィーダー５の投入口６に投入される。引手３は、パーツフィーダー５を介して、再び供給コンベア１０の上流側端部に供給される。 Then, when the second guide member 42 is in the open state, the handle 3 is guided to the downstream end by the fourth guide member 46 provided on the downstream side of the second guide member 42, and the parts feeder 5 Is inserted into the inlet 6. The handle 3 is supplied again to the upstream end of the supply conveyor 10 via the parts feeder 5.
　なお、本発明は上記実施形態に例示したものに限定されるものではなく、本発明の要旨を逸脱しない範囲において適宜変更可能である。 It should be noted that the present invention is not limited to those exemplified in the above embodiment, and can be appropriately changed without departing from the gist of the present invention.
　例えば、上述の実施形態においては、搬送物として、スライドファスナーに用いられる引手３を適用したが、特に限定されるものではなく、ボタン、機械部品、食品等、任意の搬送物を適用可能である。 For example, in the above-described embodiment, the handle 3 used for the slide fastener is applied as the transported object, but is not particularly limited, and any transported object such as a button, a machine part, or a food can be applied. .
　また、測定装置は、レーザを搬送物に照射して、反射光から搬送速度を測定するレーザ速度計を用いても良い。 Also, the measuring device may use a laser velocimeter that irradiates a conveyance object with a laser and measures the conveyance speed from reflected light.
