Description

本発明は、移動経路に沿って移動して複数種類の物品を搬送する物品搬送車に関する。 The present invention relates to an article carrier that moves along a movement path and conveys a plurality of types of articles.

例えば、特許第５７００２５５号公報（特許文献１）には、複数種類の物品それぞれに対応した複数種類の物品搬送車が開示されている。以下、背景技術の説明において括弧内に付す符号は、特許文献１のものである。 For example, Japanese Patent No. 5700255 (Patent Document 1) discloses a plurality of types of article transport vehicles corresponding to each of a plurality of types of articles. Hereinafter, the reference numerals given in parentheses in the description of the background art are those of Patent Document 1.

特許文献１には、物品搬送車として、ウェハ収納容器（Ｗ）の搬送専用の第１天井搬送車（Ｂ１）とレチクル収納容器（Ｒ）の搬送専用の第２天井搬送車（Ｂ２）とが開示されている。ウェハ収納容器（Ｗ）とレチクル収納容器（Ｒ）とは、互いに大きさや形状が異なるため、特許文献１に開示された技術では、上記のように種類の異なる物品搬送車を用いている。 Patent Document 1 describes, as article transport vehicles, a first ceiling transport vehicle (B1) dedicated to transporting a wafer storage container (W) and a second ceiling transport vehicle (B2) dedicated to transporting a reticle storage container (R). It has been disclosed. Since the wafer storage container (W) and the reticle storage container (R) are different in size and shape from each other, the technique disclosed in Patent Document 1 uses different types of article transport vehicles as described above.

特許第５７００２５５号公報Japanese Patent No. 5700255

ところで、搬送対象の物品の種類によっては、搬送頻度が異なる場合などがあるため、それぞれを搬送する物品搬送車の使用頻度も異なってくる。そのため、より効率的な運用を図るために、複数種類の物品を同じ物品搬送車により搬送可能とすることが要望されている。これが可能になれば、設備に備えられる複数の物品搬送車の使用頻度の均一化を図ることができ、効率的な運用が可能となる。しかし、物品搬送車による物品の搬送中には、当該物品搬送車からの物品の脱落を規制するための措置がとられるのが一般的であるが、上記のように大きさや形状が異なる複数種類の物品を搬送可能な物品搬送車を実現しようとする場合、複数種類の物品のそれぞれに対応した脱落規制の措置が必要となる。 By the way, since the transport frequency may differ depending on the type of the article to be transported, the frequency of use of the article transport vehicle for transporting each of the articles also differs. Therefore, in order to achieve more efficient operation, it is required that a plurality of types of articles can be transported by the same article carrier. If this becomes possible, it will be possible to equalize the frequency of use of a plurality of goods transport vehicles provided in the equipment, and efficient operation will be possible. However, while the goods are being transported by the goods transport vehicle, measures are generally taken to regulate the dropping of the goods from the goods transport vehicle, but as described above, there are a plurality of types having different sizes and shapes. In order to realize an article transport vehicle capable of transporting the articles of the above, it is necessary to take measures for dropout regulation corresponding to each of a plurality of types of articles.

上記実状に鑑みて、複数種類の物品を搬送可能な物品搬送車において、それら複数種類の物品のそれぞれについて搬送中に脱落することを適切に規制できる技術の実現が望まれる。 In view of the above situation, it is desired to realize a technique capable of appropriately restricting each of the plurality of types of articles from falling off during transportation in an article transport vehicle capable of transporting a plurality of types of articles.

移動経路に沿って移動して複数種類の物品を搬送する物品搬送車であって、
前記物品を収容する収容部と、前記収容部と当該収容部よりも下側に位置する移載対象箇所との間で前記物品の移載を行う移載機構と、前記収容部に収容された状態の前記物品が前記収容部から外側に脱落することを規制する脱落規制部と、前記収容部に収容された状態の前記物品である収容物品の種類を検出する物品検出部と、を備え、
前記移載機構は、前記物品を保持する保持部と、前記保持部を前記収容部と前記移載対象箇所との間で昇降させる昇降機構と、を備え、
前記物品には、第１種物品と、前記第１種物品よりも平面視での外形が小さい第２種物品と、の２種類が少なくとも含まれ、
前記脱落規制部は、前記収容物品の脱落を規制する規制姿勢と前記規制姿勢よりも前記収容物品から離間した離間姿勢とに姿勢変更する規制体と、前記規制体の姿勢変更を制御する規制体制御部と、を備え、
前記規制体は、前記規制姿勢において前記収容物品の下面に対向する下面対向部と、前記規制姿勢において前記収容物品の側面に対向する側面対向部と、を備え、
前記規制体制御部は、
前記物品検出部によって検出された前記収容物品の種類が前記第１種物品である場合に、前記下面対向部が上下方向に沿う上下方向視で前記第１種物品に重複する位置に配置されると共に前記側面対向部が前記上下方向視で前記第１種物品の側面に沿う位置に配置される前記規制姿勢である第１規制姿勢となるように、前記規制体を姿勢変更させ、
前記物品検出部によって検出された前記収容物品の種類が前記第２種物品である場合に、前記下面対向部が前記上下方向視で前記第２種物品に重複する位置に配置されると共に前記側面対向部が前記上下方向視で前記第２種物品の側面に沿う位置であって前記第１種物品とは重複する位置に配置される前記規制姿勢である第２規制姿勢となるように、前記規制体を姿勢変更させ、
前記保持部が前記物品を保持した状態で前記昇降機構により昇降する場合に、前記保持部に保持された前記物品の移動軌跡と重複しない位置に前記規制体が配置される前記離間姿勢となるように前記規制体を姿勢変更させる。 An article carrier that moves along a movement route and transports multiple types of articles.
A transfer mechanism for transferring the article between the accommodating portion for accommodating the article, the accommodating portion and a transfer target location located below the accommodating portion, and the accommodating portion. It is provided with a dropout control unit that regulates the article in a state from falling out from the storage unit, and an article detection unit that detects the type of the storage article that is the article in the state of being housed in the storage unit.
The transfer mechanism includes a holding portion for holding the article and an elevating mechanism for raising and lowering the holding portion between the accommodating portion and the transfer target portion.
The article includes at least two types, a first-class article and a second-class article having a smaller outer shape in a plan view than the first-class article.
The dropout control unit is a regulated body that regulates the dropout of the contained article, a regulated body that changes the posture from the regulated posture to a separated posture that is farther from the contained article, and a regulated body that controls the posture change of the regulated body. With a control unit,
The restricting body includes a lower surface facing portion facing the lower surface of the contained article in the restricted posture, and a side facing portion facing the side surface of the contained article in the restricted posture.
The regulatory body control unit
When the type of the contained article detected by the article detection unit is the first-class article, the lower surface facing portion is arranged at a position overlapping the first-class article in a vertical view along the vertical direction. At the same time, the posture of the restricting body is changed so that the side facing portion is in the first restricting posture, which is the restricting posture arranged at a position along the side surface of the first-class article in the vertical view.
When the type of the contained article detected by the article detection unit is the second type article, the lower surface facing portion is arranged at a position overlapping the second type article in the vertical view and the side surface thereof. The facing portion is located along the side surface of the second-class article in the vertical direction and is arranged at a position overlapping with the first-class article so as to be in the second restricting posture, which is the restricting posture. Change the posture of the regulator,
When the holding portion moves up and down by the elevating mechanism while holding the article, the restricting body is arranged at a position that does not overlap with the movement locus of the article held by the holding portion so as to be in the separated posture. To change the posture of the regulator.

本構成によれば、規制体制御部によって、規制体を第１規制姿勢と第２規制姿勢と離間姿勢とに姿勢変更することができる。規制体が第１規制姿勢の状態においては、下面対向部が上下方向視で第１種物品に重複する位置に配置されると共に、側面対向部が上下方向視で第１種物品の側面に沿う位置に配置されるため、下面対向部及び側面対向部によって第１種物品の脱落を適切に規制できる。また、規制体が第２規制姿勢の状態においては、下面対向部が上下方向視で第２種物品に重複する位置に配置されると共に、側面対向部が上下方向視で第２種物品の側面に沿う位置であって第１種物品とは重複する位置に配置されるため、下面対向部及び側面対向部によって第２種物品の脱落を適切に規制できる。ここで、第２規制姿勢では、側面対向部が、第１種物品と重複するほど第２種物品の側面に近い位置に配置されることから、第１種物品よりも平面視での外形が小さい第２種物品の脱落をより適切に規制できる。従って、本構成によれば、物品の種類に関係無く、搬送中における物品の脱落を適切に規制できる。さらに、規制体が離間姿勢の状態では、保持部に保持された物品が第１種物品であっても第２種物品であっても、それらの昇降移動軌跡と重複しない位置に規制体が配置されるため、保持部を収容部と移載対象箇所との間で昇降させる場合に、規制体が妨げとならないようにできる。 According to this configuration, the regulator body control unit can change the posture of the regulator body into a first regulated posture, a second regulated posture, and a separated posture. In the state where the restricting body is in the first regulation posture, the lower surface facing portion is arranged at a position overlapping the first type article in the vertical direction, and the side facing portion is along the side surface of the first type article in the vertical direction. Since it is arranged at the position, the falling off of the first-class article can be appropriately regulated by the lower surface facing portion and the side facing portion. Further, when the regulator is in the second regulated posture, the lower surface facing portion is arranged at a position overlapping the second type article in the vertical direction, and the side facing portion is arranged on the side surface of the second type article in the vertical direction. Since it is arranged at a position along the above and overlaps with the first-class article, the drop-off of the second-class article can be appropriately regulated by the lower surface facing portion and the side facing portion. Here, in the second regulation posture, the side surface facing portion is arranged at a position closer to the side surface of the second type article so as to overlap with the first type article, so that the outer shape in a plan view is larger than that of the first type article. The dropout of small second-class articles can be more appropriately regulated. Therefore, according to this configuration, it is possible to appropriately regulate the dropping of the article during transportation regardless of the type of the article. Further, in the state where the restricting body is in the separated posture, the restricting body is arranged at a position that does not overlap with the ascending / descending movement locus of both the first-class article and the second-class article held in the holding portion. Therefore, when the holding portion is moved up and down between the accommodating portion and the transfer target portion, the regulator can be prevented from becoming an obstacle.

本開示に係る技術のさらなる特徴と利点は、図面を参照して記述する以下の例示的かつ非限定的な実施形態の説明によってより明確になるであろう。 Further features and advantages of the techniques according to the present disclosure will be further clarified by the following illustration of exemplary and non-limiting embodiments described with reference to the drawings.

物品搬送車の実施形態について図面を参照して説明する。以下では、物品搬送車が、物品の搬送が行われる物品搬送設備に適用される場合を例示して、本実施形態に係る物品搬送車について説明する。 An embodiment of the article carrier will be described with reference to the drawings. Hereinafter, the article transport vehicle according to the present embodiment will be described by exemplifying a case where the article transport vehicle is applied to an article transport facility in which articles are transported.

図１及び図２に示すように、物品搬送設備は、物品８を搬送する物品搬送車Ｖと、設備の天井近くに設置され、物品搬送車Ｖの移動経路Ｒを構成するレールＲａと、物品搬送車Ｖとの間で物品８の移載が行われる移載対象箇所９と、を備えている。 As shown in FIGS. 1 and 2, the article transport equipment includes an article transport vehicle V that transports the article 8, a rail Ra that is installed near the ceiling of the equipment and constitutes a movement path R of the article transport vehicle V, and an article. It is provided with a transfer target portion 9 in which the article 8 is transferred to and from the transport vehicle V.

移載対象箇所９には、物品８に対する処理を行う処理装置９１と、処理装置９１に隣接して配置され、物品８を支持する支持台９２と、が設けられている。本実施形態では、物品搬送車Ｖは、処理装置９１による処理が行われる前の物品８を、図外の搬送元から支持台９２に搬送すると共に、処理装置９１による処理が行われた後の物品８を、支持台９２から図外の搬送先に搬送する。本実施形態では、物品８は、処理装置９１による処理の対象となる処理対象物を収納する容器であり、上述の「物品８に対する処理」とは、物品８に収納された処理対象物に対する処理を意味する。例えば、物品８としては、ウェハを収納するウェハ収納容器（いわゆるＦＯＵＰ：Front Opening Unified Pod）であっても良いし、レチクルを収容するレチクル収納容器（いわゆるレチクルポッド）であっても良い。物品８がＦＯＵＰである場合、処理対象物はウェハとされる。物品８がレチクルポッドである場合、処理対象物はレチクルとされる。 The transfer target portion 9 is provided with a processing device 91 that processes the article 8 and a support table 92 that is arranged adjacent to the processing device 91 and supports the article 8. In the present embodiment, the article transport vehicle V transports the article 8 before the processing by the processing device 91 from the transport source (not shown) to the support base 92, and after the processing by the processing device 91 is performed. The article 8 is transported from the support base 92 to a transport destination (not shown). In the present embodiment, the article 8 is a container for storing the object to be processed to be processed by the processing device 91, and the above-mentioned "processing for the article 8" means the processing for the object to be processed stored in the article 8. Means. For example, the article 8 may be a wafer storage container (so-called FOUP: Front Opening Unified Pod) for storing wafers, or a reticle storage container (so-called reticle pod) for storing reticle. When the article 8 is FOUP, the object to be processed is a wafer. When the article 8 is a reticle pod, the object to be processed is a reticle.

以下、図１～図３を参照して、物品搬送車Ｖの構成について詳細に説明する。なお、以下では、物品搬送車Ｖが移動経路Ｒに沿って物品８を搬送する方向を「搬送方向Ｘ」とする。そして、搬送方向Ｘに対して上下方向に沿う上下方向視で交差する方向を「交差方向Ｙ」とする。本例では、交差方向Ｙは、搬送方向Ｘに対して上下方向視で直交する方向である。なお、搬送方向Ｘを第１方向、交差方向Ｙを第２方向とそれぞれ言い換えても良い。第１方向と第２方向とは上下方向視で互いに交差する方向である。 Hereinafter, the configuration of the article carrier V will be described in detail with reference to FIGS. 1 to 3. In the following, the direction in which the article transport vehicle V conveys the article 8 along the movement path R is referred to as the “transport direction X”. Then, the direction in which the transport direction X intersects in the vertical direction along the vertical direction is defined as the "intersection direction Y". In this example, the crossing direction Y is a direction orthogonal to the transport direction X in the vertical direction. The transport direction X may be paraphrased as the first direction, and the crossing direction Y may be paraphrased as the second direction. The first direction and the second direction are directions that intersect each other in a vertical view.

物品搬送車Ｖは、移動経路Ｒに沿って移動して複数種類の物品８を搬送する。物品搬送車Ｖは、物品８を収容する収容部２と、収容部２と当該収容部２よりも下側に位置する移載対象箇所９との間で物品８の移載を行う移載機構４と、を備えている。本実施形態では、物品搬送車Ｖは、走行機構１と、収容部２を覆うカバー３と、を更に備えている。 The article carrier V moves along the movement path R to convey a plurality of types of articles 8.

At least one of the pair of links 531 is a drive link connected to the drive motor M53, and is driven by the drive motor M53 to rotate. By the rotation of the link 531 which is a drive link, the driving force is transmitted to the regulator 51 connected to the link 531 and another link 531 connected to the regulator 51. As a result, the regulator 51 swings along the horizontal plane. More specifically, the restricting body 51 swings in the direction of the arrow shown in FIG. 8 so as to rotate around the rotation shaft 53Ax. As a result, the restricting body 51 can move in both the transport direction X and the crossing direction Y.

このように、本実施形態では、規制体５１は、水平面に沿って揺動し、搬送方向Ｘ及び交差方向Ｙの双方に移動するように構成されている。本実施形態では、規制体５１は、搬送方向Ｘ（第１方向）及び交差方向Ｙ（第２方向）の双方に、物品８の種類に応じて異なる移動量で移動して、規制姿勢Ａｒと離間姿勢Ａｄとに姿勢変更する。規制体５１が、搬送方向Ｘに収容物品８の種類に応じて異なる移動量で移動することで、収容物品８の種類に関わらず、下面対向部５１１を収容物品８の下面８ｄに対して適切な位置に配置できると共に、側面対向部５１２を収容物品８の側面８ｓに対して適切な位置に配置できる。そして、規制体５１が、交差方向Ｙに収容物品８の種類に応じて異なる移動量で移動することで、収容物品８の種類に関わらず、前面対向部５１３を収容物品８の前面８ｆに対して適切な位置に配置できると共に、背面対向部５１４を収容物品８の背面８ｒに対して適切な位置に配置できる。 As described above, in the present embodiment, the restricting body 51 is configured to swing along the horizontal plane and move in both the transport direction X and the crossing direction Y. In the present embodiment, the restricting body 51 moves in both the transport direction X (first direction) and the crossing direction Y (second direction) with different movement amounts depending on the type of the article 8, and becomes the regulated posture Ar. The posture is changed to the separated posture Ad. By moving the restricting body 51 in the transport direction X with a different amount of movement depending on the type of the stored article 8, the lower surface facing portion 511 is suitable for the lower surface 8d of the stored article 8 regardless of the type of the stored article 8. The side surface facing portion 512 can be arranged at an appropriate position with respect to the side surface 8s of the contained article 8. Then, the restricting body 51 moves in the crossing direction Y with a different amount of movement depending on the type of the accommodation article 8, so that the front facing portion 513 is moved with respect to the front surface 8f of the accommodation article 8 regardless of the type of the accommodation article 8. The back surface facing portion 514 can be arranged at an appropriate position with respect to the back surface 8r of the contained article 8.

次に、物品搬送車Ｖの制御構成について図６を参照して説明する。 Next, the control configuration of the article carrier V will be described with reference to FIG.

The upper control device Ct and the lower control device Cv include, for example, a processor such as a microcomputer, peripheral circuits such as a memory, and the like. Then, each function is realized by the cooperation between these hardware and a program executed on a processor such as a computer.

上位制御装置Ｃｔは、物品８の搬送指令を下位制御装置Ｃｖに送信する。本実施形態では、物品搬送車Ｖは、物品８の搬送指令を上位制御装置Ｃｔから取得する指令取得部６を備えている。上位制御装置Ｃｔからの搬送指令を取得した指令取得部６は、取得した搬送指令を下位制御装置Ｃｖに送信し、下位制御装置Ｃｖは、当該搬送指令に従って物品搬送車Ｖを制御して物品８を搬送する。指令取得部６が取得する搬送指令には、当該搬送指令に係る物品８の搬送元を示す搬送元情報、及び、搬送先を示す搬送先情報が含まれる。更に本実施形態では、この搬送指令には、当該搬送指令に係る物品８の種類を示す物品種類情報が含まれる。すなわち本例では、上位制御装置Ｃｔは、搬送元と搬送先とを指定して、第１種物品８１、第２種物品８２、或いはそれ以外の物品８（例えば第Ｎ種物品）を搬送する搬送指令を、指令取得部６を介して下位制御装置Ｃｖに送信する。 The upper control device Ct transmits a transport command of the article 8 to the lower control device Cv. In the present embodiment, the article transport vehicle V includes a command acquisition unit 6 that acquires a transport command of the article 8 from the host control device Ct. The command acquisition unit 6 that has acquired the transfer command from the upper control device Ct transmits the acquired transfer command to the lower control device Cv, and the lower control device Cv controls the article transfer vehicle V according to the transfer command to make the article 8 To transport. The transport command acquired by the command acquisition unit 6 includes transport source information indicating the transport source of the article 8 related to the transport command, and transport destination information indicating the transport destination. Further, in the present embodiment, the transport command includes article type information indicating the type of the article 8 according to the transport command. That is, in this example, the upper control device Ct designates a transport source and a transport destination, and transports the first-class article 81, the second-class article 82, or the other article 8 (for example, the N-class article). The transport command is transmitted to the lower control device Cv via the command acquisition unit 6.

搬送指令を受けた下位制御装置Ｃｖは、走行機構１と移載機構４とを制御して、当該搬送指令に係る物品８の搬送及び移載を行う。本実施形態では、下位制御装置Ｃｖは、走行用モータＭ１、把持用モータＭ４１、昇降用モータＭ４２、スライド用モータＭ４３、旋回用モータＭ４４の一部又は全部を制御して、搬送指令に係る物品８の搬送及び移載を行う。 The lower control device Cv that has received the transport command controls the traveling mechanism 1 and the transfer mechanism 4 to transport and transfer the article 8 according to the transport command. In the present embodiment, the lower control device Cv controls a part or all of the traveling motor M1, the gripping motor M41, the elevating motor M42, the sliding motor M43, and the turning motor M44, and is an article related to the transport command. 8 is transported and transferred.

規制体制御部５２は、物品検出部Ｓによる物品８の種類の検出結果を取得するように構成されている。本実施形態では、規制体制御部５２は、下位制御装置Ｃｖを介して、物品検出部Ｓによる物品８の種類の検出結果を取得するように構成されている。具体的には、図６に示すように、下位制御装置Ｃｖは、物品検出部Ｓによる物品８の種類の検出結果を取得する。そして、下位制御装置Ｃｖは、物品検出部Ｓからの検出結果を規制体制御部５２に送信する。これにより、規制体制御部５２は、物品検出部Ｓによる物品８の種類の検出結果を取得する。 The regulator control unit 52 is configured to acquire the detection result of the type of the article 8 by the article detection unit S. In the present embodiment, the regulator control unit 52 is configured to acquire the detection result of the type of the article 8 by the article detection unit S via the lower control device Cv. Specifically, as shown in FIG. 6, the lower control device Cv acquires the detection result of the type of the article 8 by the article detection unit S. Then, the lower control device Cv transmits the detection result from the article detection unit S to the regulator control unit 52. As a result, the regulator control unit 52 acquires the detection result of the type of the article 8 by the article detection unit S.

規制体制御部５２は、物品検出部Ｓによる物品８の種類の検出結果に基づいて規制体駆動機構５３（駆動モータＭ５３）を制御する。そして、規制体制御部５２は、規制体駆動機構５３を制御することにより、規制体５１の姿勢を、第１規制姿勢Ａｒ１、第２規制姿勢Ａｒ２、又は離間姿勢Ａｄに変更する（図７及び図８参照）。 The regulator control unit 52 controls the regulator drive mechanism 53 (drive motor M53) based on the detection result of the type of the article 8 by the article detection unit S. Then, the restricting body control unit 52 changes the posture of the restricting body 51 to the first regulated posture Ar1, the second regulated posture Ar2, or the separated posture Ad by controlling the restricting body driving mechanism 53 (FIG. 7 and FIG. 7 and). See FIG. 8).

図７の上図に示すように、規制体制御部５２は、物品検出部Ｓによって検出された収容物品８の種類が第１種物品８１である場合に、下面対向部５１１が上下方向視で第１種物品８１に重複する位置に配置されると共に側面対向部５１２が上下方向視で第１種物品８１の側面８ｓに沿う位置に配置される規制姿勢Ａｒである第１規制姿勢Ａｒ１となるように、規制体５１を姿勢変更させる。これにより、下面対向部５１１及び側面対向部５１２によって第１種物品８１の脱落を適切に規制できる。本実施形態では、第１規制姿勢Ａｒ１では、前面対向部５１３が上下方向視で第１種物品８１の前面８ｆに沿う位置に配置され、背面対向部５１４が上下方向視で第１種物品８１の背面８ｒに沿う位置に配置される（図８参照）。これにより、収容物品８が第１種物品８１である場合において、第１種物品８１の各面に対向するように規制体５１の各部を配置することができ、第１種物品８１の収容部２からの脱落を更に適切に規制することができる。 As shown in the upper part of FIG. 7, in the restricting body control unit 52, when the type of the contained article 8 detected by the article detection unit S is the first type article 81, the lower surface facing portion 511 is viewed in the vertical direction. It becomes the first regulated posture Ar1 which is the regulated posture Ar which is arranged at the position overlapping with the first type article 81 and the side surface facing portion 512 is arranged at the position along the side surface 8s of the first type article 81 in the vertical direction. As described above, the posture of the regulator 51 is changed. Thereby, the falling off of the first-class article 81 can be appropriately regulated by the lower surface facing portion 511 and the side facing portion 512. In the present embodiment, in the first restricted posture Ar1, the front facing portion 513 is arranged at a position along the front surface 8f of the first-class article 81 in the vertical direction, and the back facing portion 514 is arranged in the vertical direction along the front surface 8f of the first-class article 81. It is arranged at a position along the back surface 8r of the above (see FIG. 8). As a result, when the contained article 8 is the first-class article 81, each part of the restricting body 51 can be arranged so as to face each surface of the first-class article 81, and the accommodating portion of the first-class article 81 can be arranged. Dropout from 2 can be regulated more appropriately.

また、図７の下図に示すように、規制体制御部５２は、物品検出部Ｓによって検出された収容物品８の種類が第２種物品８２である場合に、下面対向部５１１が上下方向視で第２種物品８２に重複する位置に配置されると共に側面対向部５１２が上下方向視で第２種物品８２の側面８ｓに沿う位置であって第１種物品８１とは重複する位置に配置される規制姿勢Ａｒである第２規制姿勢Ａｒ２となるように、規制体５１を姿勢変更させる。これにより、下面対向部５１１及び側面対向部５１２によって第２種物品８２の脱落を適切に規制できる。なお、第２規制姿勢Ａｒ２では、側面対向部５１２が上下方向視で第２種物品８２とは重複せず、第１種物品８１とは重複する位置に配置される。これにより、側面対向部５１２が上下方向視で第１種物品８１及び第２種物品８２の双方と重複しない位置に配置される場合に比べて、第２規制姿勢Ａｒ２での側面対向部５１２と第２種物品８２の側面８ｓとの対向間隔を近くすることができる。従って、側面対向部５１２によって第２種物品８２の脱落を適切に規制できる。本実施形態では、第２規制姿勢Ａｒ２では、上記の第１規制姿勢Ａｒ１の場合と同様に、前面対向部５１３が上下方向視で第２種物品８２の前面８ｆに沿う位置に配置され、背面対向部５１４が上下方向視で第２種物品８２の背面８ｒに沿う位置に配置される（図８参照）。これにより、収容物品８が第２種物品８２である場合において、第２種物品８２の各面に対向するように規制体５１の各部を配置することができ、第２種物品８２の収容部２からの脱落を更に適切に規制することができる。 Further, as shown in the lower figure of FIG. 7, in the restricting body control unit 52, when the type of the contained article 8 detected by the article detection unit S is the second type article 82, the lower surface facing portion 511 is viewed in the vertical direction. The side surface facing portion 512 is arranged at a position overlapping the type 2 article 82 and at a position along the side surface 8s of the type 2 article 82 in the vertical direction and overlapping with the type 1 article 81. The posture of the regulator 51 is changed so as to be the second regulated posture Ar2 which is the regulated posture Ar. Thereby, the falling off of the second type article 82 can be appropriately regulated by the lower surface facing portion 511 and the side facing portion 512. In the second regulated posture Ar2, the side surface facing portion 512 does not overlap with the type 2 article 82 in the vertical direction, and is arranged at a position overlapping with the type 1 article 81. As a result, as compared with the case where the side facing portion 512 is arranged at a position that does not overlap with both the first-class article 81 and the second-class article 82 in the vertical view, the side facing portion 512 in the second regulated posture Ar2 The facing distance from the side surface 8s of the second-class article 82 can be made close. Therefore, the side facing portion 512 can appropriately regulate the falling off of the second type article 82. In the present embodiment, in the second regulated posture Ar2, the front facing portion 513 is arranged at a position along the front surface 8f of the second type article 82 in the vertical direction as in the case of the first regulated posture Ar1 described above, and the back surface thereof. The facing portion 514 is arranged at a position along the back surface 8r of the second-class article 82 in the vertical direction (see FIG. 8). Thereby, when the contained article 8 is the second type article 82, each part of the restricting body 51 can be arranged so as to face each surface of the second type article 82, and the accommodating part of the second type article 82 can be arranged. Dropout from 2 can be regulated more appropriately.

また、図１及び図８に示すように、規制体制御部５２は、保持部４１が物品８を保持した状態で昇降機構４２により昇降する場合に、保持部４１に保持された物品８の移動軌跡と重複しない位置に規制体５１が配置される離間姿勢Ａｄとなるように規制体５１を姿勢変更させる。これにより、規制体５１が離間姿勢Ａｄの状態では、保持部４１に保持された物品８が第１種物品８１であっても第２種物品８２であっても、それらの昇降移動軌跡と重複しない位置に規制体５１が配置されるため、保持部４１を収容部２と移載対象箇所９との間で昇降させる場合に、規制体５１が妨げとならないようにできる。 Further, as shown in FIGS. 1 and 8, the restricting body control unit 52 moves the article 8 held by the holding unit 41 when the holding unit 41 moves up and down by the elevating mechanism 42 while holding the article 8. The posture of the restricting body 51 is changed so as to have a separated posture Ad in which the restricting body 51 is arranged at a position that does not overlap with the locus. As a result, when the restricting body 51 is in the separated posture Ad, whether the article 8 held by the holding portion 41 is the first-class article 81 or the second-class article 82, it overlaps with the up-and-down movement locus thereof. Since the restricting body 51 is arranged at a position where the restricting body 51 is not used, the restricting body 51 can be prevented from becoming an obstacle when the holding portion 41 is moved up and down between the accommodating portion 2 and the transfer target portion 9.

本実施形態では、図６に示すように、規制体制御部５２は、指令取得部６が取得する搬送指令に含まれる物品種類情報と、物品検出部Ｓによる物品８の種類の検出結果とに基づいて、規制体５１を姿勢変更させる。これにより、物品８の種類に関して、異なる情報元から取得される２つの情報に基づいて規制体５１を動作させることができ、物品８の種類に応じた確実性の高い動作を規制体に行わせることができる。なお、本例では、規制体制御部５２は、下位制御装置Ｃｖを介して、搬送指令に含まれる物品種類情報を指令取得部６から取得する。 In the present embodiment, as shown in FIG. 6, the restricting body control unit 52 uses the article type information included in the transport command acquired by the command acquisition unit 6 and the detection result of the type of the article 8 by the article detection unit S. Based on this, the regulator 51 is changed in posture. As a result, the regulator 51 can be operated based on two pieces of information obtained from different information sources regarding the type of the article 8, and the regulator is made to perform a highly reliable operation according to the type of the article 8. be able to. In this example, the regulator control unit 52 acquires the article type information included in the transport command from the command acquisition unit 6 via the lower control device Cv.

そして、規制体制御部５２は、物品種類情報に示された物品８の種類と、物品検出部Ｓによって検出された物品８の種類とが、一致している場合には、当該種類に応じた規制姿勢Ａｒとなるように規制体５１を姿勢変更させる。例えば、物品種類情報に示された物品８の種類が第１種物品８１であり、物品検出部Ｓによって検出された物品８の種類も第１種物品８１である場合には、規制体制御部５２は、規制体５１を第１規制姿勢Ａｒ１に姿勢変更させる（図７上図参照）。また、物品種類情報に示された物品８の種類が第２種物品８２であり、物品検出部Ｓによって検出された物品８の種類も第２種物品８２である場合には、規制体制御部５２は、規制体５１を第２規制姿勢Ａｒ２に姿勢変更させる（図７下図参照）。 Then, when the type of the article 8 shown in the article type information and the type of the article 8 detected by the article detection unit S match, the regulator control unit 52 corresponds to the type. The posture of the regulator 51 is changed so as to be the regulated posture Ar. For example, when the type of the article 8 shown in the article type information is the first-class article 81 and the type of the article 8 detected by the article detection unit S is also the first-class article 81, the regulator control unit. 52 causes the regulator 51 to change its posture to the first regulated posture Ar1 (see the upper figure of FIG. 7). Further, when the type of the article 8 shown in the article type information is the second type article 82 and the type of the article 8 detected by the article detection unit S is also the second type article 82, the regulator control unit. 52 causes the regulator 51 to change its posture to the second regulated posture Ar2 (see the figure below in FIG. 7).

ここで、規制体５１は、第２規制姿勢Ａｒ２の状態では、収容物品８が第１種物品８１である場合に、当該第１種物品８１と重複する位置に配置される。そのため、収容物品８の種類が第１種物品８１の場合に誤って規制体５１を第２規制姿勢Ａｒ２にすると、規制体５１が収容物品８（第１種物品８１）に干渉することになる。しかし、規制体５１の第１規制姿勢Ａｒ１は、第２種物品８２よりも外形の大きな第１種物品８１に対応した姿勢である。そのため、規制体５１が第１規制姿勢Ａｒ１の状態では、収容物品８が第１種物品８１及び第２種物品８２の何れの場合であっても、規制体５１は当該収容物品８に干渉することはない。 Here, the restricting body 51 is arranged at a position overlapping the first-class article 81 when the contained article 8 is the first-class article 81 in the state of the second regulated posture Ar2. Therefore, if the type of the contained article 8 is the first type article 81 and the restricting body 51 is mistakenly set to the second restricted posture Ar2, the restricting body 51 interferes with the contained article 8 (the first type article 81). .. However, the first regulated posture Ar1 of the regulator 51 is a posture corresponding to the first-class article 81 having a larger outer shape than the second-class article 82. Therefore, in the state where the restricting body 51 is in the first restricted posture Ar1, the restricting body 51 interferes with the contained article 8 regardless of whether the contained article 8 is the first type article 81 or the second type article 82. There is no such thing.

そこで本実施形態では、規制体制御部５２は、物品種類情報に示された物品８の種類と、物品検出部Ｓによって検出された物品８の種類とが、一致していない場合には、第１規制姿勢Ａｒ１となるように規制体５１を姿勢変更させる。すなわち本実施形態では、物品種類情報に示された物品８の種類が第１種物品８１であるにもかかわらず、物品検出部Ｓによって検出された物品８の種類が第２種物品８２である場合、及び、物品種類情報に示された物品８の種類が第２種物品８２であるにもかかわらず、物品検出部Ｓによって検出された物品８の種類が第１種物品８１である場合には、規制体制御部５２は、規制体５１を第１規制姿勢Ａｒ１に姿勢変更させる（図７上図参照）。これにより、実際の収容物品８が第１種物品８１及び第２種物品８２の何れであっても、当該収容物品８に規制体５１が干渉することを確実に防止できる。 Therefore, in the present embodiment, when the type of the article 8 shown in the article type information and the type of the article 8 detected by the article detection unit S do not match, the regulator control unit 52 is the first. 1 The posture of the regulator 51 is changed so as to be the regulated posture Ar1. That is, in the present embodiment, although the type of the article 8 shown in the article type information is the first-class article 81, the type of the article 8 detected by the article detection unit S is the second-class article 82. In the case, and when the type of the article 8 shown in the article type information is the second type article 82, but the type of the article 8 detected by the article detection unit S is the first type article 81. The regulator control unit 52 changes the posture of the regulator 51 to the first regulated posture Ar1 (see the upper figure of FIG. 7). Thereby, regardless of whether the actual contained article 8 is the first type article 81 or the second type article 82, it is possible to surely prevent the regulator 51 from interfering with the contained article 8.

本実施形態では、図７に示すように、規制体制御部５２は、第１規制姿勢Ａｒ１及び第２規制姿勢Ａｒ２の何れの状態であっても、収容物品８の被保持部８ｇから下面対向部５１１の上面までの上下方向の距離（以下、下端距離Ｄｄと称する。）が第１高さＨ１よりも大きく、収容物品８の被保持部８ｇから側面対向部５１２の上端までの距離（以下、上端距離Ｄｕと称する。）が第２高さＨ２よりも小さくなるように、規制体５１を配置する。すなわち、規制体５１が第１規制姿勢Ａｒ１及び第２規制姿勢Ａｒ２の何れの状態であっても、下端距離Ｄｄは第１高さＨ１よりも大きく、上端距離Ｄｕは第２高さＨ２よりも小さい。換言すれば、規制体５１が第１規制姿勢Ａｒ１及び第２規制姿勢Ａｒ２の何れの状態であっても、下面対向部５１１の上面は収容物品８（第１種物品８１及び第２種物品８２）の下面８ｄよりも下側に配置され、側面対向部５１２の上端は収容物品８（第１種物品８１及び第２種物品８２）の下面８ｄよりも上側に配置される。 In the present embodiment, as shown in FIG. 7, the restricting body control unit 52 faces the lower surface from the held portion 8g of the contained article 8 regardless of the state of the first regulated posture Ar1 or the second regulated posture Ar2. The vertical distance to the upper surface of the portion 511 (hereinafter referred to as the lower end distance Dd) is larger than the first height H1, and the distance from the held portion 8 g of the contained article 8 to the upper end of the side facing portion 512 (hereinafter referred to as the upper end). , The upper end distance Du) is arranged so as to be smaller than the second height H2. That is, regardless of whether the restricting body 51 is in the first regulated posture Ar1 or the second regulated posture Ar2, the lower end distance Dd is larger than the first height H1 and the upper end distance Du is larger than the second height H2. small. In other words, regardless of whether the regulator 51 is in the first regulated posture Ar1 or the second regulated posture Ar2, the upper surface of the lower surface facing portion 511 is the contained article 8 (first-class article 81 and second-class article 82). ) Is arranged below the lower surface 8d, and the upper end of the side surface facing portion 512 is arranged above the lower surface 8d of the contained article 8 (type 1 article 81 and type 2 article 82).

上述のように本例では、規制体５１は、水平面に沿って移動するように構成されており、上下方向には移動しない。従って、下面対向部５１１の上面の位置は、物品搬送車Ｖによって搬送される複数種類の物品８のうち、物品高さが最大となる物品８（本例では第１種物品８１）に合わせて、規制姿勢Ａｒにおいて当該物品８の下面８ｄよりも下側に配置されるように設定される。そして、側面対向部５１２の上端の位置は、物品搬送車Ｖによって搬送される複数種類の物品８のうち、物品高さが最小となる物品８（本例では第２種物品８２）に合わせて、規制姿勢Ａｒにおいて当該物品８の下面８ｄよりも上側に配置されるように設定される。上記の構成によれば、互いに物品高さの異なる第１種物品８１と第２種物品８２とのそれぞれに合わせて規制体５１の上下方向の位置を変更する必要が無いため、規制体制御部５２の構成を簡略化することができる。そして、規制体５１の上下方向の位置を変更することなく、規制体５１が第１規制姿勢Ａｒ１及び第２規制姿勢Ａｒ２の何れの状態であっても、下面対向部５１１と側面対向部５１２とを第１種物品８１又は第２種物品８２の脱落を規制するための適切な位置に配置することができる。 As described above, in this example, the restrictor 51 is configured to move along the horizontal plane and does not move in the vertical direction. Therefore, the position of the upper surface of the lower surface facing portion 511 is aligned with the article 8 (in this example, the first-class article 81) having the maximum article height among the plurality of types of articles 8 conveyed by the article carrier V. , It is set to be arranged below the lower surface 8d of the article 8 in the restricted posture Ar. The position of the upper end of the side facing portion 512 is aligned with the article 8 (in this example, the second type article 82) having the minimum article height among the plurality of types of articles 8 conveyed by the article carrier V. , It is set to be arranged above the lower surface 8d of the article 8 in the restricted posture Ar. According to the above configuration, since it is not necessary to change the vertical position of the restricting body 51 according to each of the type 1 article 81 and the type 2 article 82 having different article heights, the restricting body control unit The configuration of 52 can be simplified. Then, regardless of whether the regulator 51 is in the first regulated posture Ar1 or the second regulated posture Ar2, the lower surface facing portion 511 and the side facing portion 512 are formed without changing the vertical position of the regulator 51. Can be placed in an appropriate position to regulate the dropout of the first-class article 81 or the second-class article 82.

〔その他の実施形態〕
次に、物品搬送車のその他の実施形態について説明する。 [Other embodiments]
Next, other embodiments of the article carrier will be described.

（１）上記の実施形態では、物品８には、第１種物品８１と第２種物品８２との２種類が少なくとも含まれる例について説明した。従って、物品８の種類は、３種類以上であっても良い。例えば、図９に示すように、側面位置検出センサＳｗによる検出結果と下面位置検出センサＳｈによる検出結果との組み合わせに応じて検出可能な、物品幅や物品高さが異なる３種類以上の物品８が含まれていても良い。図９における縦の列には、例えば、互いに物品幅が等しく、物品高さがそれぞれ異なる第１０種物品、第１１種物品、第１２種物品…が示されている。図９における横の列には、例えば、互いに物品高さが等しく、物品幅がそれぞれ異なる第１０種物品、第２０種物品…が示されている。 (1) In the above embodiment, an example has been described in which the article 8 includes at least two types, a first-class article 81 and a second-class article 82. Therefore, the type of the article 8 may be 3 or more. For example, as shown in FIG. 9, three or more types of articles 8 having different article widths and article heights that can be detected according to the combination of the detection result by the side position detection sensor Sw and the detection result by the lower surface position detection sensor Sh. May be included. In the vertical columns in FIG. 9, for example, the tenth type article, the eleventh type article, the twelfth type article, and the like, which have the same article width and different article heights, are shown. In the horizontal columns in FIG. 9, for example, the 10th type articles, the 20th type articles, and the like, which have the same article height and different article widths, are shown.

（２）上記の実施形態では、規制体５１が、水平面に沿って揺動し、搬送方向Ｘ（第１方向）及び交差方向Ｙ（第２方向）の双方に移動するように構成されている例について説明した。しかし、このような例に限定されることなく、規制体５１は、搬送方向Ｘにのみ移動するように構成されていても良い。或いは、規制体５１は、例えば図１０に示すように、搬送方向Ｘや交差方向Ｙに加えて、上下方向にも移動するように構成されていても良い。規制体５１が移動可能な方向は、規制体５１を駆動する規制体駆動機構５３の構造により定まる。 (2) In the above embodiment, the restricting body 51 is configured to swing along the horizontal plane and move in both the transport direction X (first direction) and the crossing direction Y (second direction). An example was explained. However, without being limited to such an example, the restricting body 51 may be configured to move only in the transport direction X. Alternatively, as shown in FIG. 10, for example, the restricting body 51 may be configured to move in the vertical direction in addition to the transport direction X and the crossing direction Y. The direction in which the regulator 51 can move is determined by the structure of the regulator drive mechanism 53 that drives the regulator 51.

（３）上記の実施形態では、物品検出部Ｓが、収容物品８の側面８ｓの位置を検出する側面位置検出センサＳｗと、収容物品８の下面８ｄの位置を検出する下面位置検出センサＳｈとによって、物品８の種類を検出する例について説明した。しかし、このような例に限定されることなく、例えば、物品検出部Ｓは、収容物品８の重量を検出する重量検出センサを備え、重量検出センサによって検出された収容物品８の重量に基づいて物品８の種類を検出しても良い。この場合、物品搬送車Ｖは、搬送対象となり得る複数種類の物品８それぞれの重量を重量情報として記憶した記憶部を備え、記憶部に記憶された重量情報と重量検出センサによって検出された収容物品８の重量とに基づいて、当該収容物品８の種類を特定すると良い。 (3) In the above embodiment, the article detection unit S has a side surface position detection sensor Sw that detects the position of the side surface 8s of the contained article 8 and a lower surface position detection sensor Sh that detects the position of the lower surface 8d of the contained article 8. An example of detecting the type of the article 8 has been described. However, without being limited to such an example, for example, the article detection unit S includes a weight detection sensor that detects the weight of the contained article 8, and is based on the weight of the contained article 8 detected by the weight detection sensor. The type of article 8 may be detected. In this case, the article transport vehicle V includes a storage unit that stores the weight of each of the plurality of types of articles 8 that can be transported as weight information, and the weight information stored in the storage unit and the contained article detected by the weight detection sensor. The type of the contained article 8 may be specified based on the weight of the item 8.

（４）上記の実施形態では、側面位置検出センサＳｗが、距離センサとして構成されている例について説明した。しかし、このような例に限定されることなく、側面位置検出センサＳｗは、光軸の遮断の有無により検出位置における遮光物体の有無を検出するオンオフセンサとして構成されていても良い。また、上記の実施形態では、側面位置検出センサＳｗが、カバー３における第１カバー部３１又は第２カバー部３２に取り付けられる例について説明したが、上記のように側面位置検出センサＳｗが複数のオンオフセンサを備えて構成されている場合には、例えば側面位置検出センサＳｗはカバー３における上側カバー部３０に取り付けられていると良い。この場合、複数のオンオフセンサは、収容物品８の物品幅（搬送方向Ｘ）に沿う方向に並んで配置され、収容物品８の側面８ｓの位置を検出するように構成されていると良い。 (4) In the above embodiment, an example in which the side position detection sensor Sw is configured as a distance sensor has been described. However, without being limited to such an example, the side surface position detection sensor Sw may be configured as an on / off sensor that detects the presence / absence of a light-shielding object at the detection position depending on the presence / absence of blocking of the optical axis. Further, in the above embodiment, an example in which the side surface position detection sensor Sw is attached to the first cover portion 31 or the second cover portion 32 of the cover 3 has been described, but as described above, there are a plurality of side position detection sensors Sw. When the on / off sensor is provided, for example, the side surface position detection sensor Sw may be attached to the upper cover portion 30 of the cover 3. In this case, it is preferable that the plurality of on / off sensors are arranged side by side along the article width (transport direction X) of the contained article 8 and are configured to detect the position of the side surface 8s of the contained article 8.

（５）上記の実施形態では、下面位置検出センサＳｈは、光軸の遮断の有無により検出位置における遮光物体の有無を検出するオンオフセンサとして構成されている例について説明した。しかし、このような例に限定されることなく、下面位置検出センサＳｈは、距離センサとして構成されていても良い。この場合、下面位置検出センサＳｈは、収容物品８の下面８ｄに対して交差する方向に検出光を投光するように構成されると良い。そして、下面位置検出センサＳｈは、当該下面位置検出センサＳｈから収容物品８の下面８ｄまでの距離を検出し、この距離と、保持部４１の位置により既知である被保持部８ｇの上下方向の位置とに基づいて、収容物品８の物品高さを検出する。 (5) In the above embodiment, an example is described in which the bottom surface position detection sensor Sh is configured as an on / off sensor that detects the presence / absence of a light-shielding object at the detection position depending on the presence / absence of blocking of the optical axis. However, the bottom surface position detection sensor Sh may be configured as a distance sensor without being limited to such an example. In this case, the lower surface position detection sensor Sh may be configured to emit the detection light in a direction intersecting the lower surface 8d of the contained article 8. Then, the lower surface position detection sensor Sh detects the distance from the lower surface position detection sensor Sh to the lower surface 8d of the contained article 8, and the distance and the position of the holding portion 41 are known in the vertical direction of the held portion 8g. The article height of the contained article 8 is detected based on the position.

（６）上記の実施形態では、側面対向部５１２が、下面対向部５１１と一体的に形成されている例について説明した。しかし、このような例に限定されることなく、側面対向部５１２と下面対向部５１１とは、別々に形成されていても良い。この場合、側面対向部５１２と下面対向部５１１とは、それぞれ別の駆動機構によって駆動されても良い。 (6) In the above embodiment, an example in which the side surface facing portion 512 is integrally formed with the lower surface facing portion 511 has been described. However, the present invention is not limited to such an example, and the side surface facing portion 512 and the bottom surface facing portion 511 may be formed separately. In this case, the side facing portion 512 and the lower surface facing portion 511 may be driven by different drive mechanisms.

（７）上記の実施形態では、側面対向部５１２が板状に形成されている例について説明した。しかし、このような例に限定されることなく、側面対向部５１２は、多角柱状や円柱状に形成されていても良いし、或いは、ブロック状に形成されていても良い。 (7) In the above embodiment, an example in which the side facing portion 512 is formed in a plate shape has been described. However, without being limited to such an example, the side surface facing portion 512 may be formed in a polygonal columnar shape or a columnar shape, or may be formed in a block shape.

（８）上記の実施形態では、規制体駆動機構５３が、複数のリンクを備えたリンク機構として構成されている例について説明した。しかし、このような例に限定されることなく、規制体駆動機構５３は、リンク機構以外の公知の機構で構成されていても良い。例えば、規制体駆動機構５３は、ボールねじ等を備えた直動機構として構成されていても良い。 (8) In the above embodiment, an example in which the restrictor drive mechanism 53 is configured as a link mechanism including a plurality of links has been described. However, without being limited to such an example, the restrictor drive mechanism 53 may be configured by a known mechanism other than the link mechanism. For example, the restrictor drive mechanism 53 may be configured as a linear motion mechanism including a ball screw or the like.

（９）上記の実施形態では、脱落規制部５が、規制体５１を一対備えている例について説明した。しかし、このような例に限定されることなく、脱落規制部５は、規制体５１を１つのみ備え、或いは、３つ以上備えていても良い。 (9) In the above embodiment, an example in which the dropout control unit 5 includes a pair of regulators 51 has been described. However, without being limited to such an example, the dropout control unit 5 may include only one regulator 51, or may have three or more regulators 51.

（１０）上記の実施形態では、規制体５１が第１規制姿勢Ａｒ１及び第２規制姿勢Ａｒ２の何れの状態であっても、収容物品８の被保持部８ｇから下面対向部５１１の上面までの上下方向の距離（下端距離Ｄｄ）が第１高さＨ１よりも大きく、収容物品８の被保持部８ｇから側面対向部５１２の上端までの距離（上端距離Ｄｕ）が第２高さＨ２よりも小さい例について説明した。しかし、このような例に限定されることなく、規制体５１を上下方向に移動可能に構成し、下端距離Ｄｄと上端距離Ｄｕとを、物品８の種類に応じて変更しても良い。すなわち、収容物品８が第１種物品８１である場合において、規制体５１が、第１種物品８１に応じた第１規制姿勢Ａｒ１の状態では、上端距離Ｄｕは、第１高さＨ１より小さければ、第２高さＨ２より大きくても良い。また、収容物品８が第２種物品８２である場合において、規制体５１が、第２種物品８２に応じた第２規制姿勢Ａｒ２の状態では、下端距離Ｄｄは、第２高さＨ２より大きければ、第１高さＨ１より小さくても良い。 (10) In the above embodiment, regardless of whether the restricting body 51 is in the first regulated posture Ar1 or the second regulated posture Ar2, the distance from the held portion 8g of the contained article 8 to the upper surface of the lower surface facing portion 511. The vertical distance (lower end distance Dd) is larger than the first height H1, and the distance from the held portion 8 g of the contained article 8 to the upper end of the side facing portion 512 (upper end distance Du) is larger than the second height H2. A small example was described. However, the present invention is not limited to such an example, and the restricting body 51 may be configured to be movable in the vertical direction, and the lower end distance Dd and the upper end distance Du may be changed according to the type of the article 8. That is, when the contained article 8 is the first-class article 81, the upper end distance Du is smaller than the first height H1 when the restricting body 51 is in the state of the first regulated posture Ar1 corresponding to the first-class article 81. For example, it may be larger than the second height H2. Further, when the contained article 8 is the second type article 82, the lower end distance Dd should be larger than the second height H2 when the restricting body 51 is in the state of the second regulated posture Ar2 corresponding to the second type article 82. For example, it may be smaller than the first height H1.

（１１）上記の実施形態では、規制体制御部５２は、物品種類情報に示された物品８の種類と、物品検出部Ｓによって検出された物品８の種類とが一致していない場合には、第１規制姿勢Ａｒ１となるように規制体５１を姿勢変更させる例について説明した。しかし、このような例に限定されることなく、例えば、規制体制御部５２は、物品種類情報に示された物品８の種類と、物品検出部Ｓによって検出された物品８の種類とが一致していない場合には、規制体５１の動作を停止させてエラーを報知しても良い。 (11) In the above embodiment, the regulator control unit 52 does not match the type of the article 8 shown in the article type information with the type of the article 8 detected by the article detection unit S. , An example of changing the posture of the regulator 51 so as to be the first regulated posture Ar1 has been described. However, without being limited to such an example, for example, in the regulator control unit 52, the type of the article 8 shown in the article type information and the type of the article 8 detected by the article detection unit S are one. If not, the operation of the restrictor 51 may be stopped to notify the error.

（１２）上記の実施形態では、規制体制御部５２は、指令取得部６が取得する搬送指令に含まれる物品種類情報と、物品検出部Ｓによる物品８の種類の検出結果とに基づいて、規制体５１を姿勢変更させる例について説明した。しかし、このような例に限定されることなく、規制体制御部５２は、指令取得部６が取得する搬送指令に含まれる物品種類情報は考慮せずに、物品検出部Ｓによる物品８の種類の検出結果のみに基づいて、規制体５１を姿勢変更させても良い。或いは、規制体制御部５２は、物品検出部Ｓによる物品８の種類の検出結果は考慮せずに、指令取得部６が取得する搬送指令に含まれる物品種類情報のみに基づいて、規制体５１を姿勢変更させても良い。 (12) In the above embodiment, the regulator control unit 52 is based on the article type information included in the transport command acquired by the command acquisition unit 6 and the detection result of the type of article 8 by the article detection unit S. An example of changing the posture of the restrictor 51 has been described. However, the regulation body control unit 52 is not limited to such an example, and the restrictor control unit 52 does not consider the article type information included in the transport command acquired by the command acquisition unit 6, and the type of the article 8 by the article detection unit S. The posture of the regulator 51 may be changed based only on the detection result of. Alternatively, the restricting body control unit 52 does not consider the detection result of the type of the article 8 by the article detecting unit S, and the restricting body 51 is based only on the article type information included in the transport command acquired by the command acquiring unit 6. You may change the posture.

（１３）なお、上述した実施形態で開示された構成は、矛盾が生じない限り、他の実施形態で開示された構成と組み合わせて適用することも可能である。その他の構成に関しても、本明細書において開示された実施形態は全ての点で単なる例示に過ぎない。従って、本開示の趣旨を逸脱しない範囲内で、適宜、種々の改変を行うことが可能である。 (13) The configuration disclosed in the above-described embodiment can be applied in combination with the configuration disclosed in other embodiments as long as there is no contradiction. With respect to other configurations, the embodiments disclosed herein are merely exemplary in all respects.

本構成によれば、規制体制御部によって、規制体を第１規制姿勢と第２規制姿勢と離間姿勢とに姿勢変更することができる。規制体が第１規制姿勢の状態においては、下面対向部が上下方向視で第１種物品に重複する位置に配置されると共に、側面対向部が上下方向視で第１種物品の側面に沿う位置に配置されるため、下面対向部及び側面対向部によって第１種物品の脱落を適切に規制できる。また、規制体が第２規制姿勢の状態においては、下面対向部が上下方向視で第２種物品に重複する位置に配置されると共に、側面対向部が上下方向視で第２種物品の側面に沿う位置であって第１種物品とは重複する位置に配置されるため、下面対向部及び側面対向部によって第２種物品の脱落を適切に規制できる。ここで、第２規制姿勢では、側面対向部が、第１種物品と重複するほど第２種物品の側面に近い位置に配置されることから、第１種物品よりも平面視での外形が小さい第２種物品の脱落をより適切に規制できる。従って、本構成によれば、物品の種類に関係無く、搬送中における物品の脱落を適切に規制できる。さらに、規制体が離間姿勢の状態では、保持部に保持された物品が第１種物品であっても第２種物品であっても、それらの昇降移動軌跡と重複しない位置に規制体が配置されるため、保持部を収容部と移載対象箇所との間で昇降させる場合に、規制体が妨げとならないようにできる。 According to this configuration, the regulator body control unit can change the posture of the regulator body into a first regulated posture, a second regulated posture, and a separated posture. In the state where the restricting body is in the first regulation posture, the lower surface facing portion is arranged at a position overlapping the first type article in the vertical direction, and the side facing portion is along the side surface of the first type article in the vertical direction. Since it is arranged at the position, the falling off of the first-class article can be appropriately regulated by the lower surface facing portion and the side facing portion. Further, when the regulator is in the second regulated posture, the lower surface facing portion is arranged at a position overlapping the second type article in the vertical direction, and the side facing portion is arranged on the side surface of the second type article in the vertical direction. Since it is arranged at a position along the above and overlaps with the first-class article, the drop-off of the second-class article can be appropriately regulated by the lower surface facing portion and the side facing portion. Here, in the second regulation posture, the side surface facing portion is arranged at a position closer to the side surface of the second type article so as to overlap with the first type article, so that the outer shape in a plan view is larger than that of the first type article. The dropout of small second-class articles can be more appropriately regulated. Therefore, according to this configuration, it is possible to appropriately regulate the dropping of the article during transportation regardless of the type of the article. Further, in the state where the restricting body is in the separated posture, the restricting body is arranged at a position that does not overlap with the ascending / descending movement locus of both the first-class article and the second-class article held in the holding portion. Therefore, when the holding portion is moved up and down between the accommodating portion and the transfer target portion, the regulator can be prevented from becoming an obstacle.

In the regulated body control unit, the distance in the vertical direction from the held portion to the upper surface of the lower surface facing portion is the first height regardless of the state of the first regulated posture or the second regulated posture. It is preferable to arrange the restricting body so that the distance from the held portion to the upper end of the side surface facing portion is smaller than the second height.

本構成によれば、互いに物品高さの異なる第１種物品と第２種物品とのそれぞれに合わせて規制体の上下方向の位置を変更する必要が無いため、規制体制御部の構成を簡略化することができる。そして、規制体の上下方向の位置を変更することなく、規制体が第１規制姿勢及び第２規制姿勢の何れの状態であっても、下面対向部と側面対向部とを第１種物品又は第２種物品の脱落を規制するための適切な位置に配置することができる。 According to this configuration, it is not necessary to change the vertical position of the regulator according to each of the first-class article and the second-class article having different article heights, so that the configuration of the regulator control unit is simplified. Can be transformed into. Then, regardless of whether the regulator is in the first regulated posture or the second regulated posture, the lower surface facing portion and the side facing portion are referred to as a first-class article or a side facing portion without changing the vertical position of the regulator. It can be placed in an appropriate position to regulate the dropout of Type 2 articles.
