上記文献の搬送装置では、移送機構の移送経路が上流側コンベヤ側を向く位置まで回転させた回転台によって、該上流側コンベヤからの搬送物を受取り、続いて、移送機構の移送経路が下流側コンベヤ側を向く位置まで回転台を回転駆動させることによって搬送物の方向転換を行った後、該移送機構によって前記搬送物を該下流側コンベヤ側に送出し、一連の動作を完了させる。そして、再び上流側コンベヤ側から搬送物を受取るためには、移送機構の移送経路が上流側コンベヤ側を向く位置まで回転台を再度回転駆動させることが必要になる。 In the transport apparatus of the above-mentioned document, the transport path from the upstream conveyor is received by the turntable rotated to the position where the transport path of the transport mechanism faces the upstream conveyor side, and then the transport path of the transport mechanism is downstream. The direction of the conveyed product is changed by rotationally driving the turntable to a position facing the conveyor side, and then the conveyed product is sent to the downstream conveyor side by the transfer mechanism to complete a series of operations. In order to receive the conveyed product from the upstream conveyor side again, it is necessary to drive the rotary table again to a position where the transfer path of the transfer mechanism faces the upstream conveyor side.

搬送されてくる搬送物を方向転換した後に再び搬送する搬送装置であって、搬送物の方向転換を行う方向転換装置と、該方向転換装置に向かって搬送物を搬送するように、該方向転換装置の搬送上流側に配置された上流側コンベヤと、前記方向転換装置によって方向転換された搬送物を搬送するように、該方向転換装置の搬送下流側に配置された下流側コンベヤとを備え、前記方向転換装置は、回転駆動される回転台と、該回転台の上面側に設置された複数の移送機構とを有し、各移送機構は、回転駆動可能に支持された移送ローラに上記搬送物を載せて移送する構造とし、前記複数の移送機構は、互いの移送経路が回転台上で交差するように配置され、各移送機構における移送ローラの外周面の一部には、切欠き状の退避面が形成され、前記方向転換装置は、一の移送機構が移送ローラによって搬送物を移送している間、それ以外の移送機構が、自身の移送ローラの退避面を上側に向けて退避状態とすることにより、該移送されている最中の搬送物との干渉を防止するように構成され、移送方向に並べられた複数の移送ローラからなるローラ列を、複数列並べることにより、前記移送機構の少なくとも一部を構成し、前記方向転換装置は２列のローラ列を有する移送機構を一対備え、各移送機構の移送ローラには、搬送物の移送幅方向への変位を規制するフランジを形成したものとしてもよい。 A transport device that transports a transported object that has been transported again and then transports the transported material again, and a direction changing device that changes the direction of the transported material, and the direction changing device that transports the transported object toward the direction changing device. An upstream conveyor disposed on the transport upstream side of the apparatus, and a downstream conveyor disposed on the transport downstream side of the direction changing device so as to transport the transported material redirected by the direction changing device, The direction changing device includes a turntable that is rotationally driven and a plurality of transfer mechanisms installed on an upper surface side of the turntable, and each transfer mechanism is transported to a transfer roller that is rotatably supported. The plurality of transfer mechanisms are arranged so that their transfer paths intersect on the turntable, and a part of the outer peripheral surface of the transfer roller in each transfer mechanism is notched. The evacuation surface of the front is formed The direction changing device is configured such that while one transfer mechanism transfers a conveyed product by the transfer roller, the other transfer mechanism sets the transfer roller in the retracted state with the retracting surface of the transfer roller facing upward. At least a part of the transfer mechanism is configured by arranging a plurality of roller rows composed of a plurality of transfer rollers arranged in the transfer direction so as to prevent interference with the conveyed object being processed. The direction changing device may include a pair of transfer mechanisms having two rows of rollers, and the transfer rollers of each transfer mechanism may be provided with flanges that restrict displacement of the conveyed product in the transfer width direction .

前記方向転換装置は、一の移送機構の移送経路が上流側コンベヤ側に位置するように回転台を回転させた場合に、他の移送機構の移送経路が下流側コンベヤ側に位置するように構成されたものとしてもよい。 The direction changing device is configured such that when the turntable is rotated so that the transfer path of one transfer mechanism is positioned on the upstream conveyor side, the transfer path of the other transfer mechanism is positioned on the downstream conveyor side. It is good also as what was done .

前記方向転換装置は、一の移送機構の移送経路が上流側コンベヤ側に位置し且つ該上流側コンベヤの搬送方向を向くように回転台を回転させた場合に、他の移送機構の移送経路が下流側コンベヤ側に位置し且つ該下流側コンベヤの搬送方向を向くように構成されたものとしてもよい。 When the turntable is rotated so that the transfer path of one transfer mechanism is located on the upstream conveyor side and faces the transport direction of the upstream conveyor, the direction changing device has a transfer path of another transfer mechanism. It is good also as what was located in the downstream conveyor side and comprised so that it might face the conveyance direction of this downstream conveyor .

上流側コンベヤの搬送方向に対して、下流側コンベヤの搬送方向が、平面視で、垂直方向に設定され、前記方向転換装置は、上流側コンベヤ及び下流側コンベヤの搬送経路の延長線上の交差する部分に回転中心が設定され、一の移送機構の移送経路と、他の移送機構の移送経路とを、平面視で、上記回転中心側で直交させたものとしてもよい。 The conveyance direction of the downstream conveyor is set to a vertical direction in plan view with respect to the conveyance direction of the upstream conveyor, and the direction changing device intersects the extension line of the conveyance path of the upstream conveyor and the downstream conveyor. A rotation center may be set in the portion, and a transfer path of one transfer mechanism and a transfer path of another transfer mechanism may be orthogonal to each other on the rotation center side in a plan view .

以上の構成によれば、回転台の上面側での移送経路が、複数の移送機構によって、互いに交差するように複数形成さ、搬送物が一の移送経路を移送されている最中、他の移送経路を形成している搬送ローラは、退避面が上側に向けられて干渉が防止されるため、搬送物の上流側コンベヤから方向転換装置への受渡し時又は方向転換装置から下流側コンベヤへの受渡し時には、複数の移送機構のうちから選んだ一の移送機構の移送経路が上流側コンベヤ又は下流側コンベヤの搬送方向を向くように、回転台を回転させればよいため、回転台の上面側に形成された移送経路が１つのみの場合と比べて、該回転台の回転量が少なくなり、方向転換やそれに関係する搬送作業を迅速に行うことが可能になる。 According to the above configuration, a plurality of transfer paths on the upper surface side of the turntable are formed so as to intersect with each other by a plurality of transfer mechanisms, while the transported object is being transferred through one transfer path, The transport rollers that form the transfer path are directed toward the upper side to prevent interference, so that interference is prevented. Therefore, when the transported object is delivered from the upstream conveyor to the direction changing device or from the direction changing device to the downstream conveyor. At the time of delivery, it is only necessary to rotate the turntable so that the transfer path of one transfer mechanism selected from a plurality of transfer mechanisms faces the transport direction of the upstream conveyor or the downstream conveyor. Compared with the case where there is only one transfer path, the amount of rotation of the turntable is reduced, and the direction change and the related transport work can be performed quickly.

図１は、本発明を適用した搬送装置の構成を示す平面図である。同図に示す搬送装置は、搬送経路の一端側が一箇所（集約箇所）に集約されるように互いの搬送経路が異なる方向に向けられた複数（具体的には２つ）のコンベヤ１，２と、該集約箇所に配置された方向転換装置３とを備えている。 FIG. 1 is a plan view showing a configuration of a transport apparatus to which the present invention is applied. The transport apparatus shown in the figure has a plurality of (specifically, two) conveyors 1 and 2 in which the transport paths are directed in different directions so that one end side of the transport path is concentrated at one position (aggregation position). And the direction change apparatus 3 arrange | positioned in this aggregation location is provided.

一のコンベヤ１が搬送上流側に配置された上流側コンベヤになり、それ以外の一のコンベヤ２が搬送下流側に配置された下流側コンベヤになり、両コンベヤ１，２は、搬送経路の延長線が、上記集約箇所において、平面視で、交差（具体的には、直交）している。 One conveyor 1 becomes an upstream conveyor arranged on the upstream side of conveyance, and the other conveyor 2 becomes a downstream side conveyor arranged on the downstream side of conveyance. Both conveyors 1 and 2 extend the conveyance path. The lines intersect (specifically, are orthogonal) in plan view in the aggregated location.

上流側コンベヤ１から搬送されてくる搬送物（本例では、部品が組み付けられるワークであって、さらに具体的には、ハードディスクの直方体状の筐体）Ｗが方向転換装置３に渡され、該方向転換装置３によって方向転換された後、下流側コンベヤ２に渡され、搬送物Ｗの方向転換を含めた搬送が実行される。 A conveyed product (in this example, a work to which parts are assembled, and more specifically, a cuboid housing of a hard disk) W conveyed from the upstream conveyor 1 is passed to the direction changing device 3, and After the direction is changed by the direction changing device 3, the direction is transferred to the downstream conveyor 2, and the conveyance including the direction change of the conveyed product W is executed.

各コンベヤ１，２は、搬送方向に形成されたサイドフレーム４，７を、２列に並べた状態で、一対備えている。この一対のサイドフレーム４，４，７，７における互いの対向面（内側面）側には、それぞれ複数の搬送ローラ６，８が回転駆動可能に支持されている。 Each of the conveyors 1 and 2 includes a pair of side frames 4 and 7 formed in the transport direction, arranged in two rows. A plurality of transport rollers 6 and 8 are rotatably supported on the facing surfaces (inner side surfaces) of the pair of side frames 4, 4, 7, and 7, respectively.

具体的には、一のサイドフレーム４，４，７，７の上記対向面側には、複数の搬送ローラ６，８が、上記サイドフレーム４，７に対して垂直な軸回りに回転駆動に支持され、さらに、このような支持構造を有する複数の搬送ローラ６，８は、サイドフレーム４，７の形成方向に沿って一列に並べられて搬送ローラ列（ローラ列）Ｌ１，Ｌ２を形成している。 Specifically, a plurality of transport rollers 6 and 8 are driven to rotate around an axis perpendicular to the side frames 4 and 7 on the opposite surface side of one side frame 4, 4, 7 and 7. Further, the plurality of transport rollers 6 and 8 having such a support structure are arranged in a line along the forming direction of the side frames 4 and 7 to form transport roller arrays (roller arrays) L1 and L2. ing.

各コンベヤ１，２は、２列の搬送ローラ列Ｌ１，Ｌ１，Ｌ２，Ｌ２によって搬送経路が形成されている。各コンベヤ１，２は、搬送物Ｗを、搬送ローラ６，８上に載せ、一対の搬送ローラ列Ｌ１，Ｌ１，Ｌ２，Ｌ２間に架渡した状態で、各搬送ローラ６，８を図示しない電動式のモータ（アクチュエータ）によって回転駆動させることにより、搬送を行う。 Each of the conveyors 1 and 2 has a conveying path formed by two conveying roller rows L1, L1, L2, and L2. The conveyors 1 and 2 are not shown with the conveyance rollers 6 and 8 placed on the conveyance rollers 6 and 8 and spanned between the pair of conveyance roller rows L1, L1, L2, and L2. It is conveyed by being driven to rotate by an electric motor (actuator).

方向転換装置３は、水平板状に成形されて回転自在に支持された回転台（ターンテーブル）９を備えている。上流側コンベヤ１は、その搬送下流側の端部が、回転台９側に臨んでおり、搬送物Ｗを、回転台９側に渡す。方向転換装置３は、回転台９の回転によって搬送物Ｗの方向を転換した後、該搬送物Ｗを、搬送上流側の端部が回転台９側に臨んでいる下流側コンベア２に渡す。 The direction changing device 3 includes a turntable 9 that is formed in a horizontal plate shape and is rotatably supported. The upstream conveyor 1 has its downstream end facing the turntable 9, and delivers the conveyed product W to the turntable 9 side. The direction changing device 3 changes the direction of the conveyed product W by the rotation of the turntable 9, and then transfers the conveyed product W to the downstream conveyor 2 whose end on the upstream side of the conveyance faces the rotary table 9.

次に、図２及び図３に基づき、方向転換装置３の構成について詳述する。 Next, based on FIG.2 and FIG.3, the structure of the direction change apparatus 3 is explained in full detail.

図２は、方向転換装置の構成を示す平面図であり、図３は、方向転換装置の構成を一部破断して示す図１のＡ−Ａ断面図である。図示される方向転換装置３は、上述した回転台９と、回転台９の上面側に設置された移送機構１１とを備えている。 FIG. 2 is a plan view showing the configuration of the direction changing device, and FIG. 3 is a cross-sectional view taken along the line AA of FIG. The illustrated direction changing device 3 includes the above-described turntable 9 and a transfer mechanism 11 installed on the upper surface side of the turntable 9.

上記回転台９は、水平な円盤状をなし、鉛直方向に設定された回転軸心は、自身の円形状の中心に位置している。この回転台９は、移送機構１１と共に、図示しない昇降機構によって、昇降される。 The turntable 9 has a horizontal disk shape, and the rotation axis set in the vertical direction is located at the center of its own circular shape. The turntable 9 is lifted and lowered by a lifting mechanism (not shown) together with the transfer mechanism 11.

上記移送機構１１は、回転台９の上面側に複数（図示する例では、２つ）設けられ、これによって、回転台９の上面側には、互いに上記回転中心側で交差（本例では、直交）する複数（正確には、移送機構１と同数）の移送経路が形成されている。 A plurality (two in the illustrated example) of the transfer mechanism 11 are provided on the upper surface side of the turntable 9, thereby crossing the upper surface side of the turntable 9 on the rotation center side (in this example, A plurality of (perpendicularly, the same number as the transfer mechanism 1) transfer paths are formed.

各移送機構１１は、回転台９から上方に一体的に突出させて自身の移送方向に延びる板状の一対の支持フレーム１２，１２を備え、この一対の支持フレーム１２，１２は、該移送方向に対して垂直な方向で向い合うように対向配置されている。該一対の支持フレーム１２，１２における互いの対向面側には、該対向面と垂直な回転軸１３の軸回りに回転可能に支持された複数の移送ローラ１４が、それぞれ上記移送方向に一直線状に並べられて複数配置されている。 Each transfer mechanism 11 includes a pair of plate-like support frames 12 and 12 that protrude integrally upward from the turntable 9 and extend in the transfer direction thereof, and the pair of support frames 12 and 12 are in the transfer direction. Are arranged opposite to each other so as to face each other in a perpendicular direction. A plurality of transfer rollers 14 supported so as to be rotatable around the axis of the rotary shaft 13 perpendicular to the opposing surfaces are arranged in a straight line in the transfer direction on the opposing surfaces of the pair of support frames 12, 12. A plurality are arranged side by side.

移送ローラ１４は、自身を支持する支持フレーム１２側の端部にフランジ部１４ａが形成されて径が拡大されている。上記支持フレーム１２の対向方向（移送機構１１の幅方向）で隣接する移送ローラ１４，１４は、回転軸１３同士が同一軸心となるように配置構成され、移送方向に一直状に並べられた複数の移送ローラ１４は、移送ローラ列（ローラ列）Ｌｘｙを形成している。 The diameter of the transfer roller 14 is increased by forming a flange portion 14a at an end portion on the support frame 12 side that supports the transfer roller 14. The transfer rollers 14 and 14 adjacent to each other in the facing direction of the support frame 12 (the width direction of the transfer mechanism 11) are arranged and configured so that the rotation shafts 13 have the same axis, and are arranged in a straight line in the transfer direction. The plurality of transfer rollers 14 form a transfer roller row (roller row) Lxy.

各移送機構１１は、上記移送ローラ列Ｌｘｙを複数列（具体的には、２列）並べて、搬送物Ｗの移送経路を形成している。具体的には、移送機構１１の移送幅方向（幅方向）で隣接する一対の移送ローラ１４，１４（移送ローラ列Ｌｘｙ，Ｌｘｙ）間に、搬送物Ｗを架渡して載置した状態で、該移送ローラ１４を回転駆動させることにより、搬送物Ｗが移送される。この際、上記幅方向に隣接する移送ローラ１４，１４のフランジ１４ｂ，１４ｂによって、該幅方向への搬送物Ｗの変位が規制され、意図した移送経路（移送ローラ列Ｌｘｙの形成方向）に沿って、搬送物Ｗが移送される。 Each transfer mechanism 11 forms a transfer path for the conveyed product W by arranging a plurality of transfer roller rows Lxy (specifically, two rows). Specifically, in a state where the transported object W is placed and placed between a pair of transfer rollers 14 and 14 (transfer roller rows Lxy and Lxy) adjacent in the transfer width direction (width direction) of the transfer mechanism 11, By rotating the transfer roller 14, the conveyed product W is transferred. At this time, the flanges 14b and 14b of the transfer rollers 14 and 14 adjacent in the width direction regulate the displacement of the conveyed product W in the width direction, and follow the intended transfer path (formation direction of the transfer roller row Lxy). Thus, the conveyed product W is transferred.

また、各移送ローラ列Ｌｘｙの延長線上の両側には、それぞれ一又は複数（本例では一）のサブ移送ローラ１６が配置され、各サブ支持ローラ１６は、回転台９から垂直に立設されたサブ支持フレーム１７に、回転駆動可能に支持されている。 In addition, one or a plurality of (one in this example) sub-transfer rollers 16 are arranged on both sides of the extension line of each transfer roller row Lxy, and each sub-support roller 16 is erected vertically from the turntable 9. The sub-support frame 17 is supported so as to be rotatable.

このようにして、移送ローラ列Ｌｘｙに沿って一列に並べられた移送ローラ１４及びサブ移送ローラ１６のさらに延長線上の両側には、前記サブ支持フレーム１７に遊転状態で支持された補助ローラ１８が配置されている。ちなみに、このサブ支持フレーム１７は、該サブ支持フレーム１７が設置された移送機構１１以外の他の移送機構１１の支持フレーム１２から垂直方向に延出されている。 In this way, auxiliary rollers 18 supported on the sub-support frame 17 in an idle state on both sides of the transfer roller 14 and the sub-transfer roller 16 arranged in a line along the transfer roller row Lxy. Is arranged. Incidentally, the sub support frame 17 extends in the vertical direction from the support frame 12 of the transfer mechanism 11 other than the transfer mechanism 11 in which the sub support frame 17 is installed.

移送機構１１の幅方向に並ぶ一対のサブ移送ローラ１６，１６は、互いが同一軸心上に配置され、その外側端部に、上記フランジ１４ｂと同一の機能を有するフランジ１６ａ，１６ａが形成されている。 The pair of sub-transfer rollers 16 and 16 arranged in the width direction of the transfer mechanism 11 are arranged on the same axial center, and flanges 16a and 16a having the same function as the flange 14b are formed on the outer ends thereof. ing.

このサブ移送ローラ１６は、自身が設置された移送機構１１以外の他の移送機構１１に形成された移送経路の外側（他の移送機構１１の幅方向において、該他の移送機構１１に形成された２列の移送ローラ列Ｌｘｙ，Ｌｘｙの間よりも外側）に配置され、該他の移送機構１１による搬送物Ｗの移送の妨げになることを防止している。ちなみに、このサブ移送ローラ１６は、平面視で、上記他の移送機構１１の支持フレーム１２に一部がラップしているため、該支持フレーム１２には、切欠き状部１２ａが形成され、サブ移送ローラ１６の配置スペースが確保されている。 The sub-transfer roller 16 is formed outside the transfer path formed in another transfer mechanism 11 other than the transfer mechanism 11 in which it is installed (in the other transfer mechanism 11 in the width direction of the other transfer mechanism 11). Further, it is arranged outside the space between the two transfer roller rows Lxy and Lxy, and prevents the transfer of the conveyed product W by the other transfer mechanism 11. Incidentally, since the sub-transfer roller 16 is partially wrapped with the support frame 12 of the other transfer mechanism 11 in a plan view, the support frame 12 is formed with a notch-shaped portion 12a. An arrangement space for the transfer roller 16 is secured.

一方、移送ローラ１４は、自身が設置された移送機構１１以外の他の移送機構１１に形成された移送経路内に位置しているため、このままでは、該他の移送機構１１による搬送物Ｗの移送の際に妨げになるが、このような干渉を防止する防止手段が設けられている。この防止手段については後述する。 On the other hand, since the transfer roller 14 is located in the transfer path formed in the transfer mechanism 11 other than the transfer mechanism 11 in which the transfer roller 14 is installed, the transfer roller 14 of the transfer mechanism 11 is not changed. Preventive means are provided to prevent such interference, although this may interfere with the transfer. This prevention means will be described later.

続いて、この方向転換装置３の駆動構造について説明すると、上記構成の移送ローラ１４は、移送ローラ列Ｌｘｙ毎に設けられた電動式のモータ（アクチュエータ）１９の動力が、ベルト伝動されることにより、回転駆動される。具体的には、回転軸１３を介して移送ローラ１４と一体回転する駆動プーリ２１と、モータ１９に直接的に取付けられた出力プーリ２２と、これらのプーリ２１，２２に掛け回された伝動ベルト２３によって、該モータ１９の動力が移送ローラ１４に伝動される。 Subsequently, the drive structure of the direction changing device 3 will be described. The transfer roller 14 having the above-described configuration is configured such that the power of an electric motor (actuator) 19 provided for each transfer roller row Lxy is transmitted to the belt. , Driven to rotate. Specifically, a drive pulley 21 that rotates integrally with the transfer roller 14 via the rotating shaft 13, an output pulley 22 that is directly attached to the motor 19, and a transmission belt that is wound around these pulleys 21 and 22. 23, the power of the motor 19 is transmitted to the transfer roller 14.

ちなみに、図示する例では、移送ローラ列Ｌｘｙ毎にモータ１９が設けられ、一の移送ローラ列Ｌｘｙを構成する複数の移送ローラ１４の駆動プーリ２１の全てと、一のモータ１９の出力プーリ２１とに、単一且つ環状の伝動ベルト２３が巻き掛けられ、単一のモータ１９によって、一の移送ローラ列Ｌｘｙを構成する全ての移送ローラ１４が回転駆動されるが、該構成に限定されるものではなく、移送ローラ１４毎に個別にモータ１９を設けてもよい。 Incidentally, in the illustrated example, a motor 19 is provided for each transfer roller row Lxy, all of the drive pulleys 21 of the plurality of transfer rollers 14 constituting one transfer roller row Lxy, and the output pulley 21 of one motor 19 In addition, a single and annular transmission belt 23 is wound around and all the transfer rollers 14 constituting one transfer roller row Lxy are driven to rotate by a single motor 19, but the configuration is limited to this. Instead, a motor 19 may be provided for each transfer roller 14 individually.

上記構成のサブ移送ローラ１６は、電動式のモータ（アクチュエータ）２４の動力が、ベルト伝動されることにより、回転駆動される。具体的には、サブ移送ローラ１６と一体回転する駆動プーリ２６と、モータ２４に直接的に取付けられた出力プーリ２７と、これらのプーリ２６，２７に掛け回された伝動ベルト２８によって、該モータ２４の動力がサブ移送ローラ１６に伝動される。 The sub-transfer roller 16 having the above-described configuration is driven to rotate when the power of the electric motor (actuator) 24 is transmitted to the belt. Specifically, the motor includes a driving pulley 26 that rotates integrally with the sub-transfer roller 16, an output pulley 27 that is directly attached to the motor 24, and a transmission belt 28 that is wound around these pulleys 26 and 27. The power of 24 is transmitted to the sub transfer roller 16.

ちなみに、図示する例では、これらのプーリ２１，２２，２６，２７は、支持フレーム１２又はサブ支持フレーム１７におけるローラ１４，１６を設置した側とは反対の面側に配置され、モータ１９，２４は、ローラ１４，１６と同じ側の面に設置されている。 Incidentally, in the illustrated example, these pulleys 21, 22, 26, and 27 are disposed on the surface of the support frame 12 or the sub-support frame 17 opposite to the side where the rollers 14 and 16 are installed, and the motors 19 and 24. Are installed on the same side as the rollers 14 and 16.

続いて、この方向転換装置３のセンシング構成について説明すると、移送ローラ１４の回転位置は、出力プーリ２２側に設けられたエンコーダ等からなる回転センサ（回転位置検出手段）２９によって、検出される。なお、移送ローラ列Ｌｘｙを構成する複数の移送ローラ１４の全ての回転位置を、単一の回転センサ２９によって検出するため、該複数の移送ローラ１４の位相（回転位置）は、全て同一に設定する必要がある。なお、移送ローラ１４毎に回転センサ２９を設けることも可能であり、この場合には、このような制限はない。 Next, the sensing configuration of the direction changing device 3 will be described. The rotation position of the transfer roller 14 is detected by a rotation sensor (rotation position detecting means) 29 including an encoder or the like provided on the output pulley 22 side. Since all rotation positions of the plurality of transfer rollers 14 constituting the transfer roller row Lxy are detected by a single rotation sensor 29, the phases (rotation positions) of the plurality of transfer rollers 14 are all set to be the same. There is a need to. In addition, it is also possible to provide the rotation sensor 29 for every transfer roller 14, and in this case, there is no such limitation.

また、各移送機構１１の移送方向上流側端部と、下流側端部には、搬送物Ｗの通過（存在）を検出する通過センサ（搬送物検出手段）３１がそれぞれ設置されている。具体的には、通過センサ３１が受光部及び発光部によって搬送物Ｗを検出するように構成されている。 In addition, a passage sensor (conveyed object detection means) 31 that detects the passage (presence) of the conveyed product W is installed at an upstream end and a downstream end of each transfer mechanism 11. Specifically, the passage sensor 31 is configured to detect the conveyed product W by the light receiving unit and the light emitting unit.

移送方向上流側の通過センサ３１のみが搬送物Ｗを検出している状態は、回転台９に搬送物Ｗが搬入されている最中である。
また、移送方向上流側及び下流側の両通過センサ３１が共に搬送物Ｗを検出している状態は、回転台９への搬送物Ｗの搬入が終了し、該搬送物が回転台９の上面側に完全に載った状態である。
また、移送方向下流側の通過センサ３１のみが搬送物Ｗを検出している状態は、回転台９から搬送物Ｗが搬出されている最中である。
最後に、移送方向上流側及び下流側の両通過センサ３１が共に搬送物Ｗを検出していない状態は、回転台９からの搬送物Ｗの搬出が完了し、該回転台９に新たな搬送物Ｗも搬入されていない状態である。 The state where only the passage sensor 31 on the upstream side in the transfer direction detects the conveyed product W is in the middle of the conveyed product W being carried into the turntable 9.
In addition, when both the upstream and downstream passage sensors 31 in the transfer direction detect the transported object W, the transport of the transported object W to the turntable 9 is completed, and the transported object is the upper surface of the turntable 9. It is in the state completely put on the side.
Further, the state in which only the passage sensor 31 on the downstream side in the transfer direction detects the conveyed product W is in the middle of the conveyance of the conveyed product W from the turntable 9.
Finally, when both of the passage sensors 31 on the upstream side and the downstream side in the transfer direction do not detect the conveyed product W, the conveyance of the conveyed product W from the turntable 9 is completed, and a new transfer is made to the turntable 9. It is in a state where the object W is not carried in.

以上のような構成される本搬送装置は、自身の内装されたマイコン等からなる制御部（図示しない）の入力側に、回転センサ２９及び通過センサ３１と、回転台９の回転位置を検出するエンコーダ（回転センサ）又はポテンショメータ等からなる回転位置検出手段とを接続する一方で、制御部の出力側に、コンベヤ１，２側のモータと、方向転換装置３側のモータ１９，２４と、回転台９を回転駆動させる電動式のモータ等のアクチュエータとが接続され、該制御部は、入力側のセンシング結果に基づいて、出力側の各部を制御する。 The present conveying apparatus configured as described above detects the rotation position of the rotation sensor 29, the passage sensor 31, and the turntable 9 on the input side of a control unit (not shown) composed of its own microcomputer or the like. While connected to a rotational position detection means comprising an encoder (rotation sensor) or potentiometer, the motors on the conveyors 1 and 2 side and the motors 19 and 24 on the direction changing device 3 side are rotated on the output side of the control unit. An actuator such as an electric motor that rotates the base 9 is connected, and the control unit controls each unit on the output side based on the sensing result on the input side.

次に、図３、図４乃至図７に基づき、上述した防止手段の詳細について説明する。 Next, details of the above-described prevention means will be described with reference to FIGS. 3 and 4 to 7.

図３に示す通り、移送ローラ１４の外周面の一部には、切欠き形成或いは、切欠き状に形成されたフラットな退避面１４ａが設けられ、この退避面１４ａが上記防止手段を構成している。回転台９の上面側に配置された一の移送機構１１が搬送物Ｗを移送している間、それ以外の全移送機構１１は、自身の各移送ローラ１４を、退避面１４ａが上側を向いた退避状態に切換え、上記搬送物Ｗの移送の邪魔にならないようにする。 As shown in FIG. 3, a part of the outer peripheral surface of the transfer roller 14 is provided with a notch formation or a flat withdrawal surface 14a formed in a notch shape, and this withdrawal surface 14a constitutes the prevention means. ing. While one transfer mechanism 11 arranged on the upper surface side of the turntable 9 is transferring the conveyed product W, all the other transfer mechanisms 11 have their own transfer rollers 14 and the evacuation surface 14a facing upward. The state is switched to the retracted state so as not to obstruct the transfer of the conveyed product W.

言換えると、回転台９上に設置された複数の移送機構１１のなかで、搬送物Ｗを搬送するものは必ず１つのみであり、その他のものは、自身の各移送ローラ１４を退避状態として、上記搬送物Ｗへの干渉を防止する。ちなみに、上記回転センサ２９は、主に、この退避状態の切換の有無を検出する目的で、設けられている。 In other words, among the plurality of transfer mechanisms 11 installed on the turntable 9, only one transports the transported object W, and the other transports its own transport rollers 14 in a retracted state. As a result, interference with the conveyed product W is prevented. Incidentally, the rotation sensor 29 is provided mainly for the purpose of detecting whether or not the retracted state is switched.

図４乃至図７は、搬送物を回転台上で移送する際の各移送機構の作動順序を順次示す説明図である。回転台９上の一の移送機構１１である作動側移送機構１１Ａによって形成される移送経路が、上流側コンベヤ１側を向くように（具体的には、作動側移送機構１１Ａの移送経路における移送上流側端部が、上流側コンベヤ１の搬送下流側端部側に位置し且つ該上流側コンベヤ１の搬送経路の延長線上に前記移送経路が位置するように）、回転台９を回転させている状態（図１参照）で、搬送物Ｗを、前記上流側コンベヤ１の搬送下流側まで搬送させる（図４参照）。 4 to 7 are explanatory diagrams sequentially showing the operation order of the respective transfer mechanisms when the conveyed product is transferred on the turntable. The transfer path formed by the operation side transfer mechanism 11A which is one transfer mechanism 11 on the turntable 9 faces the upstream conveyor 1 side (specifically, transfer in the transfer path of the operation side transfer mechanism 11A). Rotating the turntable 9 so that the upstream end is located on the transport downstream end of the upstream conveyor 1 and the transfer path is located on the extension of the transport path of the upstream conveyor 1). In the state (refer FIG. 1), the conveyed product W is conveyed to the conveyance downstream side of the said upstream conveyor 1 (refer FIG. 4).

続いて、前記回転台９上に設置された作動側移送機構１１以外の移送機構１１である非作動側移送機構１１Ｂの移送ローラ１４を、退避状態になるまで回転させ、その回転位置で停止させ、その後、搬送ローラ６を回転駆動させて、搬送物Ｗを、回転台９側に向かって搬送する（図５参照）。 Subsequently, the transfer roller 14 of the non-operation side transfer mechanism 11B, which is a transfer mechanism 11 other than the operation side transfer mechanism 11 installed on the rotary table 9, is rotated until it is in the retracted state, and is stopped at the rotation position. Then, the conveyance roller 6 is driven to rotate, and the conveyed product W is conveyed toward the turntable 9 (see FIG. 5).

続いて、上記搬送によって、搬送物Ｗが、移送機構１１の移送経路の上流側端部まで達すると、その状態が上述した上流側設置の通過センサ３１によって検出され、それ以降は、作動側移送機構１１Ａの移送ローラ１４及びサブ移送ローラ１６を回転駆動させ、搬送物Ｗの回転台９上での移送を行う（図６参照）。 Subsequently, when the transported object W reaches the upstream end of the transport path of the transport mechanism 11 by the transport, the state is detected by the above-described passage sensor 31 installed on the upstream side, and thereafter, the transfer on the operating side is performed. The transfer roller 14 and the sub-transfer roller 16 of the mechanism 11A are rotationally driven to transfer the conveyed product W on the rotary table 9 (see FIG. 6).

続いて、上記移送によって、搬送物Ｗが、移送機構１１の移送経路の下流側端部まで達し、全体が回転台９上に載せられた状態になると、該状態が、上流側及び下流側にそれぞれ設置された通過センサ３１，３１によって検出され、それ以降は、作動側移送機構１１Ａの移送ローラ１４及びサブ移送ローラ１６を回転駆動が停止される（図７参照）。 Subsequently, when the conveyed product W reaches the downstream end of the transfer path of the transfer mechanism 11 by the transfer, and the entire state is placed on the turntable 9, the state becomes upstream and downstream. Detected by the passing sensors 31, 31 respectively installed, and thereafter, the rotational drive of the transfer roller 14 and the sub-transfer roller 16 of the operation side transfer mechanism 11A is stopped (see FIG. 7).

なお、非作動側移送機構１１Ｂの各移送ローラ１４の退避状態への切換は、作動側移送機構１１Ａの移送上流側に配置された通過センサ３１によって、搬送物Ｗの検出がされた後でもよく、上記した例に限定されるものではない。 The non-operating side transfer mechanism 11B may be switched to the retracted state of each transfer roller 14 after the transported object W is detected by the passage sensor 31 arranged on the upstream side of the transfer of the operating side transfer mechanism 11A. However, the present invention is not limited to the above-described example.

次に、図８に基づき、本搬送装置の作動順序を説明する。 Next, based on FIG. 8, the operation | movement order of this conveying apparatus is demonstrated.

図８は、本搬送装置の作動順序を示す工程図である。作動側移送機構１１Ａによって形成される移送経路が、上流側コンベヤ１側を向く回転位置（具体的には、作動側移送機構１１Ａの移送経路における移送上流側端部が、上流側コンベヤ１の搬送下流側端部側に位置し且つ該上流側コンベヤ１の搬送経路の延長線上に前記移送経路が位置する回転位置）で、回転台９が回転停止され、非作動側移送機構１１Ｂの移送ローラ１４が退避状態に切換えられている。 FIG. 8 is a process diagram showing an operation sequence of the transport apparatus. The transfer path formed by the operating-side transfer mechanism 11A is a rotation position where the upstream-side conveyor 1 is directed (specifically, the transfer upstream end of the transfer path of the operating-side transfer mechanism 11A is transported by the upstream-side conveyor 1). The rotation table 9 is stopped at the downstream end portion and the transfer path is positioned on the extended line of the transport path of the upstream conveyor 1, and the transfer roller 14 of the non-operation side transfer mechanism 11B is stopped. Has been switched to the retracted state.

この状態で、上流側コンベヤ１及び下流側コンベヤ２を搬送駆動させて、該上流側コンベヤ１及び下流側コンベヤ２の搬送面上にある全ての搬送物Ｗを、下流側に搬送する。この際、上述した通り、作動側移送機構１１Ａも、適宜移送駆動させる。図示する例では、上流側コンベヤ１の最下流側に位置する搬送物Ｗが回転台９の上面側に導入され、その手前（上流側）の搬送物が、該上流側コンベヤ１の最下流側まで搬送され、下流側コンベヤ２の最上流側に位置する搬送物Ｗが１ブロック分、下流側に搬送される。 In this state, the upstream conveyor 1 and the downstream conveyor 2 are transported and driven, and all the transported articles W on the transport surfaces of the upstream conveyor 1 and the downstream conveyor 2 are transported downstream. At this time, as described above, the operation-side transfer mechanism 11A is also appropriately driven to be driven. In the example shown in the figure, the conveyed product W located on the most downstream side of the upstream conveyor 1 is introduced on the upper surface side of the turntable 9, and the conveyed product in front (upstream side) is the most downstream side of the upstream conveyor 1. The conveyed product W located on the most upstream side of the downstream conveyor 2 is conveyed downstream by one block.

続いて、作動側移送機構１１Ａによって形成される移送経路が、下流側コンベヤ２側を向く回転位置（具体的には、作動側移送機構１１Ａの移送経路における移送上流側端部が、下流側コンベヤ２の搬送上流側端部側に位置し且つ該下流側コンベヤ２の搬送経路の延長線上に前記移送経路が位置する回転位置）まで、回転台９を、１／４周分、回転駆動させる。 Subsequently, the transfer path formed by the operating-side transfer mechanism 11A is turned to the downstream conveyor 2 side (specifically, the transfer upstream end in the transfer path of the operating-side transfer mechanism 11A is the downstream conveyor). 2, the rotary table 9 is driven to rotate by a quarter of a turn until it reaches the upstream end of the transport 2 and the rotational position where the transfer path is located on the extended line of the transport path of the downstream conveyor 2.

ちなみに、この方向転換装置３は、一の移送機構１１の移送経路が上流側コンベヤ２の搬送経路の延長線上に位置するように回転台９を回転させた場合に、他の一の移送機構１１の移送経路の延長線上に下流側コンベヤ２が位置するように、構成されている。 Incidentally, the direction changing device 3 is configured such that when the turntable 9 is rotated so that the transfer path of one transfer mechanism 11 is positioned on the extension line of the transport path of the upstream conveyor 2, the other transfer mechanism 11. It is comprised so that the downstream conveyor 2 may be located on the extension line | wire of this transfer path.

続いて、作動側移送機構１１Ａの移送ローラ１４を回転駆動させ、回転台９上の搬送物Ｗを、下流側コンベヤ２の最上流側に移送させる。これらの一連の工程が完了した状態では、非作動側移送機構１１Ｂの移送経路が上流側コンベヤ１の搬送経路の延長線上に位置した状態になり、該移送機構１１は、それ以降、作動側移送機構１１Ａとして機能する。そして、それまで作動側移送機構１１Ａとして機能していた移送機構１１は、非作動側移送機構１１Ｂとなり、該移送機構１１の各搬送ローラ１４を退避状態に切換え、最初の段階に戻り、以下、同様の工程を繰返す。 Subsequently, the transfer roller 14 of the operation side transfer mechanism 11 </ b> A is driven to rotate, and the conveyed product W on the turntable 9 is transferred to the most upstream side of the downstream conveyor 2. In a state where these series of steps are completed, the transfer path of the non-operating side transfer mechanism 11B is located on the extension line of the transport path of the upstream conveyor 1, and the transfer mechanism 11 thereafter operates on the operating side transfer. It functions as the mechanism 11A. Then, the transfer mechanism 11 that has been functioning as the operating-side transfer mechanism 11A until then becomes the non-operating-side transfer mechanism 11B, and the respective transport rollers 14 of the transfer mechanism 11 are switched to the retracted state, returning to the initial stage, The same process is repeated.

以上のように構成される本搬送装置によれば、回転台を９０度回転させる度に、回転台９の上面中心側で直交する移送機構１１，１１が、作動側移送機構１１Ａの機能と非作動側移送機構１１Ｂの機能との一方から他方、他方から一方に相互に入替るため、方向転換装置３が、上流側コンベヤ１から受取ったの搬送物Ｗを方向転換して下流側コンベヤ１に送出した後、その回転位置のままで、再度搬送物Ｗを受取ることが可能になり、迅速な方向転換及び搬送作業が可能になる。ちなみに、本来、方向転換装置３が、上流側コンベヤ１から受取ったの搬送物Ｗを方向転換して下流側コンベヤ１に送出した後、再度搬送物Ｗを受取るためには、一方向に９０度回転させた回転台９を、反対方向に９０度回転させて、元の回転位置に戻す必要があり、手間がかかる。 According to the present transport device configured as described above, every time the turntable is rotated 90 degrees, the transfer mechanisms 11 and 11 that are orthogonal to each other on the center of the upper surface of the turntable 9 have the functions of the operation-side transfer mechanism 11A non-functional. Since the function of the operation side transfer mechanism 11B is switched from one to the other and from the other to the other, the direction changing device 3 changes the direction of the conveyed product W received from the upstream conveyor 1 to the downstream conveyor 1. After the delivery, the conveyed product W can be received again in the rotational position, and a quick direction change and transportation work can be performed. Incidentally, in order to receive the conveyed product W again after the direction changing device 3 originally changed the direction of the conveyed product W received from the upstream conveyor 1 and sent it to the downstream conveyor 1, it is 90 degrees in one direction. The rotated turntable 9 needs to be rotated 90 degrees in the opposite direction and returned to the original rotation position, which is troublesome.

また、防止手段は、移送ローラ１４に退避面１４ａを形成すればよいため、昇降によって、互いの干渉を防止するもの等と比較して、構成もシンプルで、コストもそれ程かからない。 Moreover, since the prevention means should just form the retraction | saving surface 14a in the transfer roller 14, compared with the thing etc. which prevent mutual interference by raising / lowering, a structure is simple and cost does not so much.

また、サブ移送ローラ１６や補助ローラ１８によって、搬送物Ｗのさらにスムーズな移送が確保される他、これらのローラ１６，１８は、自身が設置されている移送機構１１以外の移送機構１１に移送経路外に配置されているため、移送ローラ１４のような切欠き状の退避面１４ａを設ける必要はなく、断面視非切欠き状の真円形に成形可能である。 Further, the sub-transfer roller 16 and the auxiliary roller 18 ensure smoother transfer of the conveyed product W, and these rollers 16 and 18 are transferred to a transfer mechanism 11 other than the transfer mechanism 11 in which the sub-transfer roller 16 and the auxiliary roller 18 are installed. Since it is arranged out of the path, it is not necessary to provide a cut-out retracting surface 14a like the transfer roller 14, and it can be formed into a perfect circle not cut in section.

なお、図１に仮想線で示す通り、方向転換装置３を集約箇所として、放射状にコンベヤ１，２を配置することも可能であり、同図に示す例では、十字状にコンベヤ１，２を配置している。これらのコンベヤ１，２は、搬送ローラ６の回転方向の反転させることにより、上流側コンベヤ１として機能しているものを、下流側コンベヤ２として機能させることや、その逆も可能であり、様々な搬送経路を形成させることが可能である。 In addition, as shown with the phantom line in FIG. 1, it is also possible to arrange the conveyors 1 and 2 radially with the direction changing device 3 as an aggregation point. In the example shown in FIG. It is arranged. These conveyors 1 and 2 can function as the downstream conveyor 2 by reversing the rotation direction of the conveying roller 6 to function as the downstream conveyor 2 and vice versa. It is possible to form a simple transport path.

また、回転台９は昇降されるため、移送機構１１による移送時の搬送物Ｗの高さと、コンベヤ１，２による搬送時の搬送物Ｗの高さとを、同一のすることは必須ではなく、高さが異なるように設定することも可能になる。 Moreover, since the turntable 9 is moved up and down, it is not essential that the height of the conveyed product W at the time of transfer by the transfer mechanism 11 and the height of the conveyed product W at the time of transfer by the conveyors 1 and 2 are the same. It is also possible to set different heights.
