Description

本発明は、物品の上面部に吸着作用する吸着部が複数配設された吸着支持部と、前記吸着支持部を移動操作する移動機構と、取り出し対象の物品の位置及び姿勢を認識する物品姿勢認識装置と、前記物品姿勢認識装置の認識結果に基づいて、複数の物品を収容する容器の外部から内部へ前記吸着支持部を移動させて、当該容器から物品を取り出すべく前記吸着支持部及び前記移動機構の作動を制御するピッキング処理を実行する制御部と、を備えた物品取出設備に関する。   The present invention relates to an adsorption support portion in which a plurality of adsorption portions that act to adsorb on the upper surface portion of an article, a moving mechanism that moves the adsorption support portion, and an article posture that recognizes the position and orientation of an article to be taken out Based on a recognition device and a recognition result of the article posture recognition apparatus, the suction support part and the suction support part to move the suction support part from the outside to the inside of a container that accommodates a plurality of articles and take out the article from the container The present invention relates to an article take-out facility provided with a control unit that executes a picking process for controlling the operation of a moving mechanism.

上記のような物品取出設備として、従来、ロボットアーム式の移動機構に取り付けられて物品を支持する吸着支持部を備え、複数の物品を収容した容器内から物品を取り出すべく、物品姿勢認識装置が認識した物品の姿勢に基づいて容器の外部から内部へ吸着支持部を移動させる形態で、支持部及び移動機構の作動を制御するピッキング処理を行うものがあった(例えば、特許文献1参照)。   As an article take-out facility as described above, an article posture recognition device has conventionally been provided with a suction support portion that is attached to a robot arm type moving mechanism and supports an article, and in order to take out the article from a container containing a plurality of articles. There is one that performs picking processing for controlling the operation of the support portion and the moving mechanism in a form in which the suction support portion is moved from the outside to the inside of the container based on the recognized posture of the article (for example, see Patent Document 1).

ピッキング処理において容器内から物品を取り出すに当たり、物品の属性(例えば重量や寸法、形状等)が異なる複数種別の物品を同一のピッキング箇所にて取り出さねばならない場合がある。しかしながら、吸着支持部は、一般に、取出し対象の物品の属性に対応してその物品を吸着支持するのに最適な形状及び吸着部の配置となるように構成されているため、異なる物品の属性毎に形状及び吸着部の配置の異なる複数の吸着支持部を用意し、取出し対象の物品の属性に応じて吸着支持部を選択して付け替える(ツールチェンジと称する)必要があった。
しかしながら、そのように構成すると、吸着支持部を付け替える間ピッキング処理ができないこととなるため、属性の異なる複数種の物品についてピッキング処理を行う場合に、ピッキングの効率が低下するという問題がある。
When taking out an article from the container in the picking process, it is sometimes necessary to take out a plurality of types of articles having different attributes (for example, weight, size, shape, etc.) at the same picking location. However, since the suction support section is generally configured to have an optimal shape and suction section arrangement for sucking and supporting the article corresponding to the attribute of the article to be taken out, It is necessary to prepare a plurality of suction support portions having different shapes and arrangement of suction portions, and select and replace the suction support portions according to the attributes of the articles to be taken out (referred to as tool change).
However, with such a configuration, the picking process cannot be performed while the suction support part is replaced. Therefore, when the picking process is performed on a plurality of types of articles having different attributes, the picking efficiency is reduced.

このため、従来、吸着支持部を、物品に吸着作用する吸着作用面において複数の吸着部を縦横に並べて備える構成とし、物品の寸法や重量に合わせて吸着作用させる吸着部を切換えるように構成されたものがあった(例えば、特許文献2参照)。   For this reason, conventionally, the adsorption support portion is configured to include a plurality of adsorption portions arranged vertically and horizontally on the adsorption acting surface that acts on the article, and is configured to switch the adsorption portion that performs the adsorption action according to the size and weight of the article. (For example, refer to Patent Document 2).

しかしながら、容器に収容される物品は、常に規定された適切な位置及び姿勢であるとは限らない。つまり、複数の物品が収容される容器から所要数の物品を取り出すことによって、容器内に物品の移動を許容するような隙間が生じた場合等には、物品は、当初位置していた位置とは異なる位置及び姿勢(例えば平面視における回転角度等)となっている虞がある。
特許文献2のような吸着支持部とした場合、物品が適切な位置及び姿勢であれば、その物品の属性に対応して吸着支持することができるものの、図13に示すように、容器C及び複数の吸着ノズル141を備える吸着支持部140の双方が平面視矩形状に形成されている場合、容器の角部では吸着支持部を平面視にて回動させることができないため、物品が容器の角部に位置し、複数の吸着部の並び方向に対して傾斜した姿勢となっている場合等には、吸着部を、当該物品を吸着するのに適切な位置に位置させることができず、取出し対象の物品を適切に取り出せない虞があった。
However, the article accommodated in the container is not always in the appropriate position and posture defined. That is, when a required number of articles are taken out from a container in which a plurality of articles are stored to create a gap that allows the movement of the article in the container, the article is placed at the position where it was originally located. May have different positions and postures (for example, a rotation angle in a plan view).
In the case of the suction support portion as in Patent Document 2, if the article is in an appropriate position and posture, it can be sucked and supported in accordance with the attribute of the article, but as shown in FIG. When both of the suction support portions 140 including a plurality of suction nozzles 141 are formed in a rectangular shape in a plan view, the suction support portion cannot be rotated in a plan view at a corner portion of the container. In the case where it is positioned at the corner and inclined with respect to the direction in which the plurality of suction portions are arranged, the suction portion cannot be positioned at an appropriate position for sucking the article, There is a possibility that the article to be taken out cannot be taken out properly.

本発明は、上記実情に鑑みてなされたものであって、その目的は、容器内での位置及び姿勢並びに属性が異なる複数種の物品を容器内から取り出す場合において、吸着支持部にて適正に取出し対象の物品を取り出すことができる物品取出設備を提供することにある。   The present invention has been made in view of the above circumstances, and the object thereof is to appropriately use the suction support portion when taking out a plurality of types of articles having different positions, postures, and attributes in the container from the container. An object of the present invention is to provide an article take-out facility that can take out an article to be taken out.

このように、第8特徴構成によれば、ピッキング処理に係る制御構成を簡略化することができる。
In addition to any one of the first to seventh characteristic configurations, the eighth characteristic configuration of the article take-out facility according to the present invention is such that the control unit follows the attribute of the article to be taken out and the depth direction of the article. The position and orientation in the direction view and the position and orientation in the direction view along the depth direction of the suction support part are stored in advance in association with each other, and in the picking process, in the direction view along the depth direction. The position and orientation of the suction support portion of the article are stored in association with the attributes of the article to be taken out and the position and orientation of the article as recognized in the depth direction recognized by the article attitude recognition device.

Thus, according to the eighth characteristic configuration, the control configuration related to the picking process can be simplified.

本発明にかかる物品取出設備の第特徴構成は、上記第特徴構成に加えて、前記制御部は、前記容器の収納空間を前記奥行方向に沿う方向視で線対称又は回転対称となる複数の単位空間に分割して、当該単位空間のうちの1つである基準空間について、当該容器に収容される物品の前記奥行方向に沿う方向視での位置及び姿勢と、前記奥行方向に沿う方向視での前記吸着支持部の位置及び姿勢とを対応付けて管理するように構成され、
且つ、前記複数の単位空間のうち前記基準空間以外の単位空間に存在する物品を取出す場合には、前記基準空間における前記奥行方向に沿う方向視での物品の位置及び姿勢と前記奥行方向に沿う方向視での前記吸着支持部の位置及び姿勢との対応関係を、前記取出し対象の物品の存在する単位空間における前記奥行方向に沿う方向視での物品の位置及び姿勢と前記奥行方向に沿う方向視での前記吸着支持部の位置及び姿勢との対応関係に変換し、当該変換した対応関係に基づいて、前記取出し対象の物品に対する前記吸着支持部の前記奥行方向に沿う方向視での位置及び姿勢を導出するように構成されている点にある。
The ninth feature configuration of the article take-out equipment according to the present invention is such that, in addition to the eighth feature configuration, the control unit has a plurality of line symmetry or rotational symmetry in the container storage space as viewed in the direction along the depth direction. The reference space, which is one of the unit spaces, is divided into a unit space, and the position and posture of the article accommodated in the container as viewed in the direction along the depth direction, and the direction along the depth direction It is configured to manage the position and posture of the suction support part in association with each other,
And when taking out the article | item which exists in unit spaces other than the said reference space among these unit spaces, it follows the position and attitude | position of the article | item and the said depth direction in the direction view along the said depth direction in the said reference space. The relationship between the position and posture of the suction support part in the direction view, and the direction along the depth direction in the unit space where the article to be taken out is located along the depth direction in the unit space. Converted into a correspondence relationship with the position and orientation of the suction support portion in view, and based on the converted correspondence relationship, the position in the direction view along the depth direction of the suction support portion with respect to the article to be taken out and The point is that the posture is derived.

すなわち、複数の単位空間のうち基準空間以外の単位空間に存在する物品を取出す場合には、基準空間における奥行方向に沿う方向視での物品の位置及び姿勢と奥行方向に沿う方向視での吸着支持部の位置及び姿勢との対応関係を、取出し対象の物品の存在する単位空間における奥行方向に沿う方向視での物品の位置及び姿勢と奥行方向に沿う方向視での吸着支持部の位置及び姿勢との対応関係に変換するものであるから、当該容器に収容される物品の奥行方向に沿う方向視での位置及び姿勢と、奥行方向に沿う方向視での吸着支持部の位置及び姿勢とを対応付けたデータ(以降、対応付けデータと称する)を、上記収納空間を分割した分割数に伴って削減することができる。   That is, when an article existing in a unit space other than the reference space among a plurality of unit spaces is taken out, the position and posture of the article in the direction view along the depth direction in the reference space and the suction in the direction view along the depth direction The correspondence relationship between the position and orientation of the support portion is determined based on the position and posture of the article in the direction along the depth direction in the unit space where the article to be taken out exists, and the position of the suction support portion in the direction view along the depth direction, and Since it is to be converted into a correspondence relationship with the posture, the position and posture of the article accommodated in the container in the direction view along the depth direction, and the position and posture of the suction support portion in the direction view along the depth direction Can be reduced with the number of divisions obtained by dividing the storage space.

説明を加えると、容器の収納空間を前記奥行方向に沿う方向視で線対称又は回転対称となる複数の単位空間に分割し、その単位空間のうちの1つである基準空間における対応付けデータに基づいて、基準空間以外の単位空間の対応付けデータを導出するから、対応付けデータの総量は、全ての単位空間について対応付けデータを管理する場合に較べて1/(単位空間の分割数)で済むことになる。すなわち、容器に収容される物品の奥行方向に沿う方向視での位置及び姿勢と、奥行方向に沿う方向視での吸着支持部の位置及び姿勢とを対応付けたデータの量を、上記収納空間を分割した分割数に伴って削減することができる。
そして、単位空間は容器の収納空間を前記奥行方向に沿う方向視で線対称又は回転対称となるように分割されているから、基準空間における奥行方向に沿う方向視での物品の位置及び姿勢と奥行方向に沿う方向視での吸着支持部の位置及び姿勢との対応関係を、取出し対象の物品の存在する単位空間における奥行方向に沿う方向視での物品の位置及び姿勢と奥行方向に沿う方向視での吸着支持部の位置及び姿勢との対応関係に変換する操作は、線対称又は回転対象等の座標変換を行うのみで済むものとなり、その属性並びに位置及び姿勢を有する物品と取り出すのに適した吸着支持部の奥行方向に沿う方向視での位置及び姿勢を容易に導出できるものとなる。
このように、上記第9特徴構成によれば、ピッキング処理に係る制御構成を簡略化し、しかも、容器に収容される物品の奥行方向に沿う方向視での位置及び姿勢と、奥行方向に沿う方向視での吸着支持部の位置及び姿勢とを対応付けて管理するときのデータ量を削減することが可能となる。
In other words, the storage space of the container is divided into a plurality of unit spaces that are line-symmetric or rotationally symmetric in a direction view along the depth direction, and the correspondence data in the reference space that is one of the unit spaces Based on this, since the association data of the unit spaces other than the reference space is derived, the total amount of the association data is 1 / (number of divisions of the unit space) compared to the case where the association data is managed for all the unit spaces. It will be over. That is, the amount of data in which the position and posture of the article accommodated in the container as viewed in the direction along the depth direction and the position and posture of the suction support portion as viewed in the direction along the depth direction are associated with each other in the storage space. Can be reduced with the number of divisions.
Since the unit space is divided so that the container storage space is line-symmetric or rotationally symmetric in the direction view along the depth direction, the position and posture of the article in the direction view in the depth direction in the reference space The relationship between the position and posture of the suction support portion in the direction view along the depth direction, and the direction along the depth direction in the position and posture of the article in the direction of the depth in the unit space where the article to be taken out exists. The operation for converting into the correspondence relationship between the position and orientation of the suction support portion with the sight is only to perform coordinate transformation such as line symmetry or rotation target, and it is possible to take out the article having the attribute, position and orientation. It is possible to easily derive the position and posture of the suitable suction support portion as viewed in the direction along the depth direction.
Thus, according to the ninth characteristic configuration, the control configuration related to the picking process is simplified, and the position and posture of the article accommodated in the container as viewed in the direction along the depth direction, and the direction along the depth direction. It is possible to reduce the amount of data when managing the position and posture of the suction support portion in association with each other.

また、ピッキング処理の実行時には、制御部は、取り出し対象の物品の属性並びに当該物品の奥行方向に沿う方向視での位置及び姿勢と、吸着支持部の奥行方向に沿う方向視での位置及び姿勢とを対応付けて、例えばデータベース等に予め記憶している。したがって、制御部は、取出し対象の物品の属性並びに物品姿勢認識装置にて認識した当該物品の奥行方向に沿う方向視での位置及び姿勢に係るデータに基づいて、上記データベース等に記憶されたデータの対応関係に基づいて、その属性並びに位置及び姿勢である物品と、その物品を取り出すのに適した吸着支持部の奥行方向に沿う方向視での位置及び姿勢を、複雑な計算を行うことなく容易に導出することができる。
このように、第10特徴構成によれば、ピッキング処理に係る制御構成を簡略化することができる。
また、複数の単位空間のうち基準空間以外の単位空間に存在する物品を取出す場合には、基準空間における奥行方向に沿う方向視での物品の位置及び姿勢と奥行方向に沿う方向視での吸着支持部の位置及び姿勢との対応関係を、取出し対象の物品の存在する単位空間における奥行方向に沿う方向視での物品の位置及び姿勢と奥行方向に沿う方向視での吸着支持部の位置及び姿勢との対応関係に変換するものであるから、当該容器に収容され
る物品の奥行方向に沿う方向視での位置及び姿勢と、奥行方向に沿う方向視での吸着支持部の位置及び姿勢とを対応付けたデータ(以降、対応付けデータと称する)を、上記収納空間を分割した分割数に伴って削減することができる。
説明を加えると、容器の収納空間を前記奥行方向に沿う方向視で線対称又は回転対称となる複数の単位空間に分割し、その単位空間のうちの1つである基準空間における対応付けデータに基づいて、基準空間以外の単位空間の対応付けデータを導出するから、対応付けデータの総量は、全ての単位空間について対応付けデータを管理する場合に較べて1/(単位空間の分割数)で済むことになる。すなわち、容器に収容される物品の奥行方向に沿う方向視での位置及び姿勢と、奥行方向に沿う方向視での吸着支持部の位置及び姿勢とを対応付けたデータの量を、上記収納空間を分割した分割数に伴って削減することができる。
そして、単位空間は容器の収納空間を前記奥行方向に沿う方向視で線対称又は回転対称となるように分割されているから、基準空間における奥行方向に沿う方向視での物品の位置及び姿勢と奥行方向に沿う方向視での吸着支持部の位置及び姿勢との対応関係を、取出し対象の物品の存在する単位空間における奥行方向に沿う方向視での物品の位置及び姿勢と奥行方向に沿う方向視での吸着支持部の位置及び姿勢との対応関係に変換する操作は、線対称又は回転対象等の座標変換を行うのみで済むものとなり、その属性並びに位置及び姿勢を有する物品と取り出すのに適した吸着支持部の奥行方向に沿う方向視での位置及び姿勢を容易に導出できるものとなる。
このように、上記第10特徴構成によれば、ピッキング処理に係る制御構成を簡略化し、しかも、容器に収容される物品の奥行方向に沿う方向視での位置及び姿勢と、奥行方向に沿う方向視での吸着支持部の位置及び姿勢とを対応付けて管理するときのデータ量を削減することが可能となる。
That is, in order to take out an article located near the corner of the container, when the suction support portion is positioned at the corner of the container, a triangular shape formed by two adjacent specific sides forming the outer edge of the suction support portion The suction support portion is taken out and brought close to the article to be taken out in a posture in which the apex of the face is opposed to the corner portion.
Since the suction support portion is provided with a plurality of suction portions arranged along the two specific sides, even if the article to be taken out is large, the plurality of suction portions along the two specific sides. Can be stably adsorbed and supported.
Moreover, the suction support portion has a minimum interior angle at which the angle formed by the two specific sides forming the triangular apex is the smallest interior angle among the interior angles of the plurality of corners in a direction view along the depth direction of the container. Since the suction support portion is rotated in a direction view along the depth direction, a plurality of the plurality of the suction support portions are arranged in a line along each of the specific two sides. It is possible to take out the suction portion and make it a state along the posture of the article to be taken out.
For this reason, even when the article to be taken out is located at the corner of the container, the plurality of suction portions can be appropriately adsorbed on the upper surface of the article, and the article can be properly taken out in a stable posture. .
As described above, according to the tenth characteristic configuration, when a plurality of types of articles having different positions, orientations, and attributes in the container are taken out from the container, the article to be taken out can be properly taken out by the suction support portion. It is possible to provide a possible article take-out facility.
Further, at the time of executing the picking process, the control unit, the attribute of the article to be taken out, the position and orientation of the article in the direction along the depth direction, and the position and orientation of the suction support unit in the direction along the depth direction Are stored in advance in, for example, a database. Therefore, the control unit stores the data stored in the database or the like based on the attribute of the item to be taken out and the data related to the position and posture in the direction along the depth direction of the article recognized by the article posture recognition device. Based on the correspondence relationship, the article having the attribute, position, and posture, and the position and posture in the direction along the depth direction of the suction support portion suitable for taking out the article can be calculated without performing complicated calculations. It can be easily derived.
Thus, according to the tenth characteristic configuration, the control configuration related to the picking process can be simplified.
Further, when taking out an article existing in a unit space other than the reference space among the plurality of unit spaces, the position and posture of the article in the direction along the depth direction in the reference space and the suction in the direction along the depth direction The correspondence relationship between the position and orientation of the support portion is determined based on the position and posture of the article in the direction along the depth direction in the unit space where the article to be taken out exists, and the position of the suction support portion in the direction view along the depth direction, and Since it is converted into a correspondence relationship with the posture, it is stored in the container.
Data that associates the position and orientation of the article to be viewed in the direction along the depth direction with the position and orientation of the suction support portion in the direction view along the depth direction (hereinafter referred to as association data). It can be reduced with the number of divisions of the space.
In other words, the storage space of the container is divided into a plurality of unit spaces that are line-symmetric or rotationally symmetric in a direction view along the depth direction, and the correspondence data in the reference space that is one of the unit spaces Based on this, since the association data of the unit spaces other than the reference space is derived, the total amount of the association data is 1 / (number of divisions of the unit space) compared to the case where the association data is managed for all the unit spaces. It will be over. That is, the amount of data in which the position and posture of the article accommodated in the container as viewed in the direction along the depth direction and the position and posture of the suction support portion as viewed in the direction along the depth direction are associated with each other in the storage space. Can be reduced with the number of divisions.
Since the unit space is divided so that the container storage space is line-symmetric or rotationally symmetric in the direction view along the depth direction, the position and posture of the article in the direction view in the depth direction in the reference space The relationship between the position and posture of the suction support portion in the direction view along the depth direction, and the direction along the depth direction in the position and posture of the article in the direction of the depth in the unit space where the article to be taken out exists. The operation for converting into the correspondence relationship between the position and orientation of the suction support portion with the sight is only to perform coordinate transformation such as line symmetry or rotation target, and it is possible to take out the article having the attribute, position and orientation. It is possible to easily derive the position and posture of the suitable suction support portion as viewed in the direction along the depth direction.
Thus, according to the tenth feature configuration, the control configuration related to the picking process is simplified, and the position and posture of the article accommodated in the container as viewed in the direction along the depth direction, and the direction along the depth direction. It is possible to reduce the amount of data when managing the position and posture of the suction support portion in association with each other.

本発明にかかる物品取出設備の第12特徴構成は、上記第11特徴構成に加えて、前記制御部が、取り出し対象の物品の属性並びに前記物品姿勢認識装置にて認識した当該物品の前記奥行方向に沿う方向視における位置及び姿勢に基づいて、前記複数の吸着部のうち当該物品に対して吸着状態とする前記吸着部を選択し、選択された前記吸着部を前記吸着状態とするように前記吸着部の作動を制御する点にある。 The twelfth characteristic configuration of the article take-out facility according to the present invention is the depth direction of the article recognized by the control unit attribute and the article posture recognition device in addition to the eleventh characteristic configuration. Based on the position and orientation in the direction view along the line, the suction part that is in the suction state with respect to the article is selected from the plurality of suction parts, and the selected suction part is in the suction state. The point is to control the operation of the suction part.

すなわち、複数の吸着部のうち当該物品に対して吸着状態とする吸着部を、取り出し対象の物品の属性、並びに、物品姿勢認識装置にて認識した容器の奥行方向に沿う方向視における当該物品の位置及び姿勢に基づいて選択するから、取出し対象の物品を吸着支持するのに適切な吸着部のみを選択して吸着状態とすることができる。
したがって、吸着作用に寄与しない吸着部も吸着状態に切換えて無駄なエネルギーを消費するという事態を適切に回避することが可能となる。
That is, among the plurality of suction portions, the suction portion that is in the suction state with respect to the article is selected as the attribute of the article to be taken out and the direction of the article in the direction along the depth direction of the container recognized by the article posture recognition device.

移動機構を駆動する方法は周知であるため、説明は省略する。
As shown in FIG. 2, the picking robot P includes a pedestal 30 fixed to the floor surface of the picking area, a support cylinder 31 that can move up and down and rotate around a vertical axis, and a support cylinder 31. A first arm 32 that is pivotally supported by a horizontal shaft 36 that extends along the horizontal plane and that can swing about the horizontal shaft 36 as a swing shaft, and an end portion of the first arm 32 opposite to the horizontal shaft 36. A swingable second arm 33 having a horizontal shaft 37 provided as a swinging shaft, and a horizontal shaft 38 provided at an end opposite to the horizontal shaft 37 of the second arm 33 being swingable. The moving mechanism is provided with a rotation shaft member 34, and an adsorption support portion 40 in which a plurality of adsorption portions that adsorb on the upper surface portion of the article B are arranged.
Since the method of driving the moving mechanism is well known, the description is omitted.

吸着支持部40は、図3及び図4に示すように、側面視で回動軸部材34の軸心方向Jzと直交する平面に沿い、かつ、回動軸部材34の軸心方向Jzと直交する方向視で三角形状に形成された支持台座41と、回動軸部材34の軸心方向Jzに平行な軸心に沿って設けられる吸着部としての複数の吸着ノズルNとを備えている。
複数の吸着ノズルNのノズルチップ42t及びノズルチップ43tの先端部は、支持台座41と平行な同一平面内に位置するようになっている。このノズルチップ42t及びノズルチップ43tの先端が位置する平面が吸着作用面に相当する。回動軸部材34の水平軸38側端部には図示しない回動駆動部が設けられ、回動軸部材34の軸本体部分と吸着支持部40とを一体に軸心方向Jz周りで回動自在に支持している。すなわち、移動機構は、複数の吸着ノズルNよる吸着作用面に垂直な軸心を持つ駆動軸芯により吸着支持部40を回動自在に支持している。また、吸着ノズルNの夫々には、図示しない真空発生装置及びノズルバルブ60(図7参照)に連通するチューブ44が接続されている。
As shown in FIGS. 3 and 4, the suction support part 40 is along a plane orthogonal to the axial direction Jz of the rotating shaft member 34 in a side view and orthogonal to the axial direction Jz of the rotating shaft member 34. And a plurality of suction nozzles N as suction portions provided along an axial center parallel to the axial direction Jz of the rotation shaft member 34.
The tip portions of the nozzle tips 42 t and the nozzle tips 43 t of the plurality of suction nozzles N are positioned in the same plane parallel to the support base 41. The plane on which the tips of the nozzle tip 42t and the nozzle tip 43t are located corresponds to the suction action surface. A rotation drive unit (not shown) is provided at the end of the rotation shaft member 34 on the horizontal shaft 38 side, and the shaft main body portion of the rotation shaft member 34 and the suction support portion 40 are integrally rotated about the axial direction Jz. Supports freely. That is, the moving mechanism rotatably supports the suction support portion 40 by the drive shaft core having an axis perpendicular to the suction action surface by the plurality of suction nozzles N. Each of the suction nozzles N is connected to a tube 44 communicating with a vacuum generator (not shown) and a nozzle valve 60 (see FIG. 7).

図5に示すように、ケースCは、物品Bを載置支持する底面部Cbと、その底面部Cbから直交する方向に沿って底面部Cbから起立して平面視形状が凸多角形となるように形成された側周部Csとを備え、かつ、底面部Cbが水平面に沿う姿勢において、収容する複数の物品Bの上面が側周部Csの上端よりも低い位置となる状態で収容するように構成されている。
なお、ケースCとしては、物品の納入元から物品を収容した状態で納品される通い函や段ボール箱等がある。段ボール箱の場合、入庫されて自動倉庫に収納される前、或いは、自動倉庫から取り出した時点で、段ボール箱上部のフラップ部分を切り取り、ケース上端が開口した状態とする。
As shown in FIG. 5, the case C has a bottom surface Cb on which the article B is placed and supported, and rises from the bottom surface Cb along a direction orthogonal to the bottom surface Cb, and the shape in plan view becomes a convex polygon. In the posture in which the bottom surface Cb is along the horizontal plane, the top surfaces of the plurality of articles B to be stored are stored in a state of being lower than the upper end of the side peripheral portion Cs. It is configured as follows.
Examples of the case C include a return box and a cardboard box that are delivered in a state in which the article is received from the supplier of the article. In the case of a cardboard box, the flap portion at the upper part of the cardboard box is cut out before being stored in the automatic warehouse or taken out from the automatic warehouse, and the upper end of the case is opened.

図5においては、ケースCを、その奥行方向に沿う方向視で矩形状に形成している(図6(a)参照)。この場合には、その内角の角度は全て等しい。すなわち、θ1(θ1a=θ1b=θ1c=θ1d)=90°である。   In FIG. 5, the case C is formed in a rectangular shape as viewed in the direction along the depth direction (see FIG. 6A). In this case, the inner angles are all equal. That is, θ1 (θ1a = θ1b = θ1c = θ1d) = 90 °.

図3及び図4に示すように、吸着ノズルNとして、物品Bに対する吸着面積が異なる第1吸着体としての第1吸着ノズル42と第2吸着体としての第2吸着ノズル43とが備えられている。第1吸着ノズル42のノズルチップ42tの吸着面積は、第2吸着ノズル43のノズルチップ43tの吸着面積よりも小さく構成されている。具体的には、第1吸着ノズル42及び第2吸着ノズル43の先端に取り付けられるノズルチップ42t、43tの吸着部分は円形に形成され、直径で略1:2となるように構成されているため、吸着面積は略1:4となる。   As shown in FIGS. 3 and 4, the suction nozzle N includes a first suction nozzle 42 as a first suction body having a different suction area with respect to the article B and a second suction nozzle 43 as a second suction body. Yes. The suction area of the nozzle tip 42t of the first suction nozzle 42 is configured to be smaller than the suction area of the nozzle tip 43t of the second suction nozzle 43. Specifically, the suction portions of the nozzle tips 42t and 43t attached to the tips of the first suction nozzle 42 and the second suction nozzle 43 are formed in a circular shape and are configured to have a diameter of approximately 1: 2. The adsorption area is approximately 1: 4.

支持台座41は、回動軸部材34の軸心方向Jzと直交する方向視において、三角形状の頂点を形成する特定2辺(辺T1及び辺T2)のなす角度θが、後述するケースCの奥行方向に沿う方向視での複数の角部の内角のうち角度が最も小さな内角である最小内角の角度θ1の半分であるように形成されている(正多角形又は矩形の場合には、全ての内角の角度が等しいため、最小内角は何れかの内角の角度となる)。
また、収容する物品の形状によっては、ケースCを多角形状に形成する場合も考えられる。例えば、図6(b)に示すように平面視形状が扁平な6角形である場合、内角の角度は、θ2a=θ2d<θ2b=θ2c=θ2e=θ2fである。このような場合、特定2辺(辺T1及び辺T2)のなす角度θは、角度が最も小さな内角である最小内角の角度(図6(b)の場合、角度θ2a又は角度θ2d)の半分とする。
The support pedestal 41 has an angle θ formed by two specific sides (side T1 and side T2) that form a triangular apex in a direction perpendicular to the axial direction Jz of the rotating shaft member 34. It is formed so that it is half of the angle θ1 of the minimum inner angle that is the smallest inner angle among the inner angles of the plurality of corners in the direction view along the depth direction (in the case of a regular polygon or a rectangle, all Since the interior angles of are equal, the minimum interior angle is any interior angle).
Further, depending on the shape of the article to be stored, the case C may be formed in a polygonal shape. For example, as shown in FIG. 6B, when the planar view shape is a flat hexagon, the inner angle is θ2a = θ2d <θ2b = θ2c = θ2e = θ2f. In such a case, the angle θ formed by the two specific sides (side T1 and side T2) is half the angle of the minimum inner angle (in the case of FIG. 6B, the angle θ2a or the angle θ2d) that is the smallest inner angle. To do.

すなわち、吸着支持部40は、取出し対象の物品Bに対して吸着作用するときの姿勢において、底面部Cbと直交するケースCの奥行方向に沿う方向視で吸着支持部40の外縁を形成する隣り合う特定2辺のなす角度が、ケースCの奥行方向に沿う方向視での複数の角部の内角のうち角度が最も小さな内角である最小内角の角度よりも小さい角度であるように形成されている。
なお、以降の説明において、底面部Cbと直交するケースCの奥行方向に沿う方向をケース奥行方向と称し、底面部Cbと直交するケースCの奥行方向に沿う方向視をケース奥行方向視と称する。
That is, the suction support part 40 forms an outer edge of the suction support part 40 as viewed in the direction along the depth direction of the case C orthogonal to the bottom surface part Cb in the posture when the suction support part 40 is suctioned with respect to the article B to be taken out. The angle formed by the two specific sides to be matched is formed so as to be smaller than the angle of the smallest interior angle, which is the smallest interior angle among the interior angles of the plurality of corners in the direction view along the depth direction of the case C. Yes.
In the following description, the direction along the depth direction of the case C orthogonal to the bottom surface portion Cb is referred to as the case depth direction, and the direction view along the depth direction of the case C orthogonal to the bottom surface portion Cb is referred to as the case depth direction view. .

なお、ケース奥行方向視での形状が複数種存在する場合は、吸着支持部40における隣り合う特定2辺のなす角度は、それら複数種のケースCのうち、ケース奥行方向視での形状での内角の角度が最小のものよりも小さい角度とすることになる。
また、回動軸部材34の軸心方向Jzは、吸着ノズルNが取出し対象の物品Bに対して吸着作用するときの姿勢において、ケース奥行方向と同一である。
In addition, when there are a plurality of types in the case depth direction view, the angle formed by the two adjacent sides in the suction support portion 40 is the shape in the case depth direction view among the plurality of types of cases C. The angle of the inner angle is smaller than the smallest one.
Further, the axial center direction Jz of the rotation shaft member 34 is the same as the case depth direction in the posture when the suction nozzle N performs the suction action on the article B to be taken out.

上記第1吸着ノズル42は、回動軸部材34の軸心方向Jzと直交する方向視において支持台座41の特定2辺、すなわち辺T1と辺T2との夫々に沿って並ぶ状態で列をなして設けられている。また、辺T1に沿う第1吸着ノズル42のノズル列と辺T2に沿う第1吸着ノズル42のノズル列とは、三角形状の頂点に近い位置に設けられる頂点部ノズル42cを兼用する状態で、夫々のノズル列が4つの第1吸着ノズル42を備える状態となるように設けられている。頂点部ノズル42cは、第2吸着ノズル43よりも三角形状の頂点に近い位置に設けられている。
すなわち、特定2辺の一方の辺に沿って並ぶ複数の吸着ノズルNにおける三角形状の頂点に最も近い位置の吸着ノズルNと、特定2辺の他方の辺に沿って並ぶ複数の吸着ノズルNにおける三角形状の頂点に最も近い位置の吸着ノズルNとが兼用されている。

Is provided. In addition, the nozzle row of the first suction nozzle 42 along the side T1 and the nozzle row of the first suction nozzle 42 along the side T2 are combined with the vertex nozzle 42c provided at a position near the triangular vertex. Each nozzle row is provided with four first suction nozzles 42. The vertex nozzle 42 c is provided at a position closer to the triangular vertex than the second suction nozzle 43.
That is, in the suction nozzle N closest to the triangular apex of the plurality of suction nozzles N arranged along one side of the specific two sides and the plurality of suction nozzles N arranged along the other side of the specific two sides The suction nozzle N closest to the triangular apex is also used.

制御部Hは、例えばCPUと記憶装置を備えたコンピュータにて構成され、図7に示すように、物品姿勢認識装置R、上位管理装置Hu、及びスケジューラScと相互に通信自在に構成されている。
上位管理装置Huは、例えばCPUと記憶装置を備えたコンピュータにて構成され、複数種の物品B夫々の種別についての属性(縦、横、高さ等の寸法、形状、及び、重量等)を管理している。
制御部Hは、制御プログラムをプログラムモジュールとして実装し、各制御内容に対応するプログラムモジュールの実行によって、制御を行うように構成される。上記プログラムモジュールとして、物品姿勢認識装置Rから入力される情報に基づいて、物品の位置及び姿勢の判定を行う位置判定部H1、ピッキングロボットPの移動機構Yを制御する移動制御部H2、吸着支持部40に備える複数の第1吸着ノズル42及び第2吸着ノズル43の吸着状態を各別に制御する吸着制御部H3に対応するプログラムモジュールが実行されている。
The control unit H is configured by, for example, a computer including a CPU and a storage device, and is configured to be able to communicate with the article posture recognition device R, the upper management device Hu, and the scheduler Sc as shown in FIG. .
The upper management device Hu is constituted by a computer having a CPU and a storage device, for example, and has attributes (vertical, horizontal, height and other dimensions, shapes, weights, etc.) for each of the plurality of types of articles B. I manage.
The control unit H is configured to perform control by mounting a control program as a program module and executing the program module corresponding to each control content. As the program module, based on information input from the article posture recognition device R, a position determination unit H1 that determines the position and posture of the article, a movement control unit H2 that controls the movement mechanism Y of the picking robot P, and suction support A program module corresponding to the suction controller H3 that controls the suction states of the plurality of first suction nozzles 42 and the second suction nozzles 43 provided in the unit 40 is executed.

さらに、制御部Hにおいてはデータベースプログラムが実行され、取り出し対象の種別の物品Bの属性(縦、横、高さ等の寸法、形状、及び、重量等)並びに当該物品のケース奥行方向視での位置及び姿勢と、吸着支持部40のケース奥行方向視での位置、姿勢、及び、複数の吸着ノズルNのうちいずれの吸着ノズルNを使用するかを表すパターンとを対応付けてデータベースDBに予め記憶するように構成されている。   Further, in the control unit H, a database program is executed, and the attributes (size, shape, weight, etc., such as height, width, height, etc.) of the article B of the type to be taken out and the case depth direction view of the article. The position and orientation, the position and orientation of the suction support unit 40 as viewed in the case depth direction, and a pattern representing which suction nozzle N to use among the plurality of suction nozzles N are associated with each other in advance in the database DB. It is configured to memorize.

上記複数の第1吸着ノズル42及び第2吸着ノズル43は、各別にノズルバルブ60に接続されている。ノズルバルブ60は、吸着制御部H3によって各別にその開閉を制御されるため、複数の第1吸着ノズル42の夫々、及び、第2吸着ノズル43は、各別にその吸着状態を吸着状態と非吸着状態とに切り換え自在である。   The plurality of first suction nozzles 42 and second suction nozzles 43 are individually connected to the nozzle valve 60. Since the nozzle valve 60 is controlled to be opened and closed by the adsorption control unit H3, each of the plurality of first adsorption nozzles 42 and the second adsorption nozzle 43 has its adsorption state and adsorption state individually. The state can be switched freely.

物品姿勢認識装置Rは、例えばCPUと記憶装置を備えたコンピュータにて構成され、撮像用カメラ50が電気的に接続されている。そして、撮像用カメラ50にて撮像されたケース奥行方向視の画像を取得すると、パターンマッチングにて取出し対象の物品Bの位置を認識し、ケース奥行方向視における特定の角部を原点とした座標を制御部Hに出力する。つまり、物品姿勢認識装置Rは、取り出し対象の物品Bの位置及び姿勢を認識するように構成されている。   The article posture recognition device R is configured by a computer including a CPU and a storage device, for example, and is electrically connected to an imaging camera 50. When the case depth direction image captured by the imaging camera 50 is acquired, the position of the article B to be taken out is recognized by pattern matching, and the coordinates with the specific corner in the case depth direction as the origin are used. Is output to the control unit H. That is, the article orientation recognition device R is configured to recognize the position and orientation of the article B to be taken out.

また、制御部Hは、物品姿勢認識装置Rによって認識されるケースCの収納空間をケース奥行方向視で線対称又は回転対称となる複数の単位空間に分割して認識するように構成されている。例えば、ケース奥行方向視で矩形状の容器であれば、図11に示すように、対向する各辺の中点同士を結ぶ線分によって区切られる4つの空間に分割して認識する。   In addition, the control unit H is configured to recognize the storage space of the case C recognized by the article posture recognition device R by dividing it into a plurality of unit spaces that are line-symmetric or rotationally symmetric when viewed from the case depth direction. . For example, in the case of a rectangular container as viewed in the case depth direction, as shown in FIG. 11, the container is recognized by being divided into four spaces divided by line segments connecting the midpoints of the opposing sides.

そして、そのうちの1つの空間(図12においてはIで示す領域)を基準空間として認識するようになっている。制御部Hが備えるデータベースDBには、基準空間について、当該ケースCに収容される物品Bのケース奥行方向視での位置及び姿勢と、ケース奥行方向視での吸着支持部40の位置及び姿勢とが対応付けて管理されている。   One of the spaces (region indicated by I in FIG. 12) is recognized as a reference space. In the database DB provided in the control unit H, with respect to the reference space, the position and posture of the article B accommodated in the case C as viewed from the case depth direction, and the position and posture of the suction support unit 40 as viewed from the case depth direction. Are managed in association with each other.

データベースDBには、具体的には、以下のようなデータが記憶されている。
(1)物品の寸法
(2)物品の姿勢(ケース奥行方向視でのケースCの特定辺に対する回転角度。所定角度(例えば、10°)ごとに区切って管理する)
(3)ケースC内において物品が存在する領域(図12にて4分割した空間I〜IVのうち物品が存在する空間)
(4)複数の吸着ノズルNのうちいずれの吸着ノズルNを使用するかを表すパターン
(5)吸着支持部40のケースCへの進入時のケース奥行方向視での姿勢
上記のうち、(1)〜(3)のすべての組合わせに対して、(4)、(5)の夫々を対応付けたマトリックスとなっている。
なお、物品BがケースCの側周部近傍に位置する場合、吸着支持部40の姿勢によっては、吸着支持部40をケースCに進入させるときに吸着支持部40がケースCの側周部に干渉する虞がある。このため、データベースDBを構築する際に、物品BがケースCの側周部近傍に位置する場合においては、ケースCの側周部との位置を考慮している。具体的には、吸着支持部40とケースCの側周部が干渉する虞のない位置では、物品Bのケース奥行方向視での姿勢及び形状によって上記(4)、(5)に係るデータが決定され、吸着支持部40とケースCの側周部が干渉する虞がある位置では、物品Bのケース奥行方向視での姿勢及び形状に加えて、ケースCの側周部と吸着支持部40との位置関係を考慮して上記(4)、(5)に係るデータが決定されている。
Specifically, the following data is stored in the database DB.
(1) Dimension of article (2) Posture of article (rotation angle with respect to a specific side of case C as viewed in the case depth direction. Divided and managed every predetermined angle (for example, 10 °))
(3) A region where an article exists in case C (a space where an article exists among the spaces I to IV divided into four in FIG. 12)
(4) Pattern indicating which suction nozzle N is used among the plurality of suction nozzles N (5) Posture in the case depth direction when the suction support portion 40 enters the case C Among the above, (1 ) To (3) is a matrix in which (4) and (5) are associated with each other.
When the article B is located in the vicinity of the side peripheral portion of the case C, depending on the posture of the suction support portion 40, the suction support portion 40 may be placed on the side peripheral portion of the case C when the suction support portion 40 enters the case C. There is a risk of interference. For this reason, when the database DB is constructed, when the article B is located in the vicinity of the side periphery of the case C, the position of the case C with respect to the side periphery is taken into consideration. Specifically, in the position where there is no possibility that the suction support portion 40 and the side peripheral portion of the case C interfere with each other, the data related to the above (4) and (5) depends on the posture and shape of the article B as viewed in the case depth direction. In the determined position where the suction support portion 40 and the side peripheral portion of the case C may interfere with each other, the side periphery of the case C and the suction support portion 40 in addition to the posture and shape of the article B as viewed in the case depth direction. The data according to the above (4) and (5) is determined in consideration of the positional relationship between

また、制御部Hを構成するコンピュータには、外部インタフェースを介してピッキングロボットPの移動機構Yを制御する制御ボックス(図示省略)が接続され、制御部Hの移動制御部H2からの制御情報に基づいてアクチュエータを駆動させる。
さらに、制御部Hには、本実施形態の物品収納設備におけるスタッカークレーン10、入出庫コンベヤ20、入荷コンベヤ25、出荷コンベヤ24、ピッキング用コンベヤ22及び仕分台車21の作動を制御する制御部も備えられている。
In addition, a control box (not shown) for controlling the movement mechanism Y of the picking robot P is connected to the computer constituting the control unit H via an external interface, and control information from the movement control unit H2 of the control unit H is included in the control information. Based on this, the actuator is driven.
Furthermore, the control unit H also includes a control unit that controls the operations of the stacker crane 10, the loading / unloading conveyor 20, the receiving conveyor 25, the shipping conveyor 24, the picking conveyor 22, and the sorting cart 21 in the article storage facility of the present embodiment. It has been.

次に、制御部Hが実行する制御を、図8のフローチャートに基づいて説明する。
制御部Hは、スケジューラScから物品Bの取出し指令データを受信すると、スタッカークレーン10、入出庫コンベヤ20、仕分台車21、及びピッキング用コンベヤ22に順次取出し対象の物品を収容したケースCの搬送を指令する(ステップ#1)。
ピッキングエリアの取出し用箇所22Cにピッキング対象の物品Bを収容するケースCが搬送されると、ケース識別装置がケースCの側面に取り付けられたケース識別情報を読み取り、制御部Hにケース識別情報を送信する。制御部Hは、ケース識別装置から受け取ったケース識別情報を上位管理装置Huに送信するとともに、物品姿勢認識装置Rに位置情報取得指令を指令する(ステップ#2)。
上位管理装置Huは、制御部Hから受け取ったケース識別情報に基づいて、そのケース識別情報に対応するケースCに収納されている物品Bの属性データ(縦、横、高さ等の寸法、形状、及び、重量等)を制御部Hに対して送信する。
Next, the control executed by the control unit H will be described based on the flowchart of FIG.
When the control unit H receives the take-out command data for the article B from the scheduler Sc, the control unit H sequentially transports the case C containing the articles to be taken out to the stacker crane 10, the loading / unloading conveyor 20, the sorting cart 21, and the picking conveyor 22. Command (step # 1).
When the case C containing the article B to be picked is transported to the picking area 22C in the picking area, the case identification device reads the case identification information attached to the side surface of the case C, and the control unit H receives the case identification information. Send. The control unit H transmits the case identification information received from the case identification device to the upper management device Hu and instructs the article posture recognition device R to receive a position information acquisition command (step # 2).
Based on the case identification information received from the control unit H, the upper management device Hu attribute data (size, shape such as length, width, height) of the article B stored in the case C corresponding to the case identification information. , And weight) to the control unit H.

物品姿勢認識装置Rは、ステップ#2の位置情報取得指令が指令されると、撮像用カメラ50にてケースCの上方からケース奥行方向視のケースC全体の画像を撮像する。物品姿勢認識装置Rは、撮像用カメラ50で撮像した画像に対してパターンマッチング処理を行い、ケースCの平面視形状、取出し対象の物品の存在位置、及び、取出し対象の物品の姿勢を座標データとして制御部Hに送信する。制御部Hは、物品姿勢認識装置Rから受信した座標データに基づいて、取出し対象の物品BのケースC内における位置及び姿勢を認識する位置姿勢認識処理を実行する(ステップ#3)。   When the position information acquisition command in step # 2 is instructed, the article posture recognition device R captures an image of the entire case C as viewed from the case depth direction with the imaging camera 50 from above the case C. The article orientation recognition apparatus R performs pattern matching processing on the image captured by the imaging camera 50, and coordinates data representing the shape of the case C in plan view, the position of the article to be taken out, and the attitude of the article to be taken out. To the control unit H. Based on the coordinate data received from the article posture recognition device R, the control unit H executes position and posture recognition processing for recognizing the position and posture of the article B to be taken out in the case C (step # 3).

制御部Hは、物品姿勢認識装置Rから受信した座標データと上位管理装置Huから受信した物品Bの属性データとに基づいて、取出し対象の物品Bのケース奥行方向視での中心座標(以降、単に物品Bの中心座標と称する)が基準空間に存在するか否かを判別する(ステップ#4)。基準空間とは、上述したようにケースCの収納空間をケース奥行方向視で線対称又は回転対称となる複数の単位空間に分割したうちの特定の1つの単位空間であり、ケース奥行方向視での形状毎に定義されている。   Based on the coordinate data received from the article orientation recognition device R and the attribute data of the article B received from the host management device Hu, the control unit H determines the center coordinates (hereinafter referred to as the case depth direction) of the article B to be taken out. It is determined whether or not “the center coordinates of the article B” are present in the reference space (step # 4). The reference space is a specific unit space among the plurality of unit spaces that are linearly or rotationally symmetric in the case depth direction view as described above, and the case C view in the case depth direction view. It is defined for each shape.

取出し対象の物品Bの中心座標が基準空間に存在しないと判別すると(ステップ#4:No)、制御部Hは、基準空間におけるケース奥行方向視での物品Bの位置座標を、基準空間と取出し対象の物品Bが存在する単位空間との位置関係に基づく鏡像操作又は回転操作等のベクトル演算にて変換する座標変換処理を実行する(ステップ#5)。
具体的には、図12に示す領域IIに取出し対象の物品Bが存在するときは、鏡像操作S12を適用し、領域IIIに取出し対象の物品Bが存在するときは、鏡像操作S13を適用し、領域IVに取出し対象の物品Bが存在するときは、回転操作S14を適用する。
If it is determined that the center coordinates of the article B to be taken out do not exist in the reference space (step # 4: No), the control unit H takes out the position coordinates of the article B in the reference space as viewed from the case depth direction and the reference space. Coordinate conversion processing is performed for conversion by vector operation such as mirror image operation or rotation operation based on the positional relationship with the unit space where the target article B exists (step # 5).
Specifically, when the article B to be taken out exists in the area II shown in FIG. 12, the mirror image operation S12 is applied, and when the article B to be taken out exists in the area III, the mirror image operation S13 is applied. When the article B to be taken out exists in the area IV, the rotation operation S14 is applied.

ステップ#4にて、取出し対象の物品Bが基準空間に存在すると判別された場合、又は、ステップ#5の座標変換処理が完了した場合には、引き続いて、上位管理装置Huから受信した物品Bの属性データと、上記座標変換処理によって変換した取出し対象の物品Bのケース奥行方向視での位置座標及び姿勢とに基づいて、データベースDBから、対応する吸着支持部40のケース奥行方向視での位置座標、姿勢、及び使用する吸着ノズルNを決定する(ステップ#6)。なお、ステップ#5にて座標変換処理を行った場合におけるステップ#6の処理に対しては、吸着支持部40のケース奥行方向視での位置座標及び姿勢を上記座標変換処理の逆変換にて変換することにより、物品Bが存在する空間における、取出し対象の物品Bに対する吸着支持部40のケース奥行方向視での位置座標、姿勢、及び、使用する吸着ノズルNを決定することになる。   If it is determined in step # 4 that the article B to be taken out exists in the reference space, or if the coordinate conversion process in step # 5 is completed, the article B received from the upper management device Hu is subsequently continued. And the position coordinates and orientation of the item B to be taken out converted by the coordinate conversion process in the case depth direction, from the database DB, the corresponding suction support unit 40 in the case depth direction The position coordinates, orientation, and suction nozzle N to be used are determined (step # 6). In addition, with respect to the process of step # 6 when the coordinate conversion process is performed in step # 5, the position coordinates and orientation of the suction support portion 40 as viewed in the case depth direction are converted by the reverse conversion of the coordinate conversion process. By converting, in the space where the article B exists, the position coordinates and posture of the suction support part 40 with respect to the article B to be taken out as viewed in the case depth direction, and the suction nozzle N to be used are determined.

ステップ#6が実行されると、吸着支持部40の位置及び姿勢、並びに、使用する吸着ノズルNが決定することになる。引き続き、制御部Hは、決定された姿勢で吸着支持部40を取出し対象の物品Bに近づける形態で、当該物品についての吸着位置に位置させるように吸着支持部40及び移動機構Yの作動を制御するピッキング処理を実行する(ステップ#7)。
なお、制御部Hは、決定された姿勢で吸着支持部40を取出し対象の物品Bに近づける際に、上位管理装置Huから受信した物品Bの属性情報のうち物品の高さ方向の寸法に係る情報と、物品姿勢認識装置Rによって認識されたその物品のケース奥行方向での位置情報とに基づいて、吸着支持部40のケース奥行方向での移動距離を決定し、移動機構Yの作動を制御する。
When step # 6 is executed, the position and orientation of the suction support unit 40 and the suction nozzle N to be used are determined. Subsequently, the control unit H controls the operation of the suction support unit 40 and the moving mechanism Y so that the suction support unit 40 is brought close to the article B to be taken out in the determined posture so as to be positioned at the suction position for the article. The picking process is executed (step # 7).
Note that the control unit H relates to the size in the height direction of the article among the attribute information of the article B received from the upper management apparatus Hu when the suction support unit 40 is taken out and brought close to the article B to be picked up in the determined posture. Based on the information and the position information of the article in the case depth direction recognized by the article posture recognition device R, the movement distance of the suction support portion 40 in the case depth direction is determined, and the operation of the movement mechanism Y is controlled. To do.

データベースDBには、図9に示すように物品BがケースCの角部近傍に存在する場合には、吸着支持部40の特定2辺T1、T2で形成される三角形状の頂点を当該角部に対向させた姿勢とするように吸着支持部40の位置及び姿勢を記憶している。よって、図9に示すように、ケースCの角部に位置する物品Bを取り出すべく吸着支持部40をケースCの角部近傍に位置させる場合に、吸着支持部40における吸着ノズルNが取出し対象の物品Bの上面を適切に吸着できる姿勢となる姿勢とすることができる。   In the database DB, when the article B exists in the vicinity of the corner portion of the case C as shown in FIG. 9, the triangular apex formed by the specific two sides T1 and T2 of the suction support portion 40 is shown in the corner portion. The position and posture of the suction support portion 40 are stored so as to be opposed to each other. Therefore, as shown in FIG. 9, when the suction support portion 40 is positioned in the vicinity of the corner portion of the case C in order to take out the article B located at the corner portion of the case C, the suction nozzle N in the suction support portion 40 is an object to be taken out. It can be set as the attitude | position used as the attitude | position which can adsorb | suck the upper surface of the article | item B appropriately.

なお、図9は、物品Bに対して吸着作用可能な吸着ノズルNの数(有効ノズル数)が3つである場合を示している。比較例として、図11に示すように吸着支持部40の特定2辺T1、T2のなす角度を最小内角の角度の半分より大きい角度とした場合(図11の場合、最小内角90°に対して特定2辺T1、T2のなす角度は60°)、3つの有効ノズルを確保しようとすると、図11(b)に示すように吸着支持部40がケースCの側周部Csと干渉してしまうことになる。このように、特定2辺のなす角度が、前記最小内角の角度の半分とすることで、吸着支持部40がケースCの側周部Csと干渉する事態を回避して適切に取出し対象の物品を取り出すことができる。   FIG. 9 shows a case where the number of suction nozzles N that can act on the article B (the number of effective nozzles) is three. As a comparative example, as shown in FIG. 11, when the angle formed by the two specific sides T1 and T2 of the suction support portion 40 is larger than half of the minimum internal angle (in the case of FIG. 11, the minimum internal angle is 90 °). The angle formed by the specific two sides T1 and T2 is 60 °). If three effective nozzles are to be secured, the suction support portion 40 interferes with the side peripheral portion Cs of the case C as shown in FIG. It will be. As described above, the angle formed by the two specific sides is half of the angle of the minimum inner angle, thereby avoiding a situation in which the suction support portion 40 interferes with the side peripheral portion Cs of the case C and appropriately taking out the article to be taken out. Can be taken out.

すなわち、制御部Hは、ピッキング処理において、ケースCの角部に位置する物品Bを取り出す場合には、吸着支持部40の特定2辺で形成される三角形状の頂点を当該角部に対向させた姿勢で吸着支持部40を取出し対象の物品に近づける形態で、当該物品Bについての吸着位置に位置させるように構成されている。   That is, when picking up the article B located at the corner of the case C in the picking process, the control unit H causes the triangular apex formed by the two specific sides of the suction support unit 40 to face the corner. The suction support part 40 is taken out in the posture to be close to the article to be taken out and is positioned at the suction position for the article B.

また、図10には、上記有効ノズル数が3つである場合において、物品Bの姿勢が異なる例を示している。データベースDBには、図10のような場合には第2吸着ノズル43とその両側に存在する第1吸着ノズル42の3つの吸着ノズルNによって物品Bを吸着するように吸着支持部40の位置及び姿勢を記憶している。第2吸着ノズル43は、第1吸着ノズル42よりも吸着面積が大きいので、物品Bに対して吸着作用する力が大きく、物品Bをより確実に吸着支持することができる。   FIG. 10 shows an example in which the posture of the article B is different when the number of effective nozzles is three. In the database DB, in the case of FIG. 10, the position of the suction support portion 40 so as to suck the article B by the three suction nozzles N of the second suction nozzle 43 and the first suction nozzle 42 present on both sides thereof. I remember my posture. Since the second suction nozzle 43 has a larger suction area than the first suction nozzle 42, the force acting on the article B is large, and the article B can be supported by suction more reliably.

また、制御部Hは、ピッキング処理において、ケース奥行方向視での吸着支持部40の位置及び姿勢を、取出し対象の物品Bの属性並びに物品姿勢認識装置Rにて認識した当該物品Bのケース奥行方向視での位置及び姿勢に対応付けて記憶された位置及び姿勢とすべく、移動機構Yの作動を制御するように構成されている。   Further, in the picking process, the control unit H recognizes the position and posture of the suction support unit 40 as viewed in the case depth direction by the attribute of the item B to be taken out and the case depth of the item B recognized by the item posture recognition device R. The operation of the moving mechanism Y is controlled so as to obtain the position and posture stored in association with the position and posture in the direction view.

また、制御部Hは、複数の単位空間のうち基準空間以外の単位空間に存在する物品Bを取出す場合には、基準空間におけるケース奥行方向視での物品Bの位置及び姿勢とケース奥行方向視での吸着支持部40の位置及び姿勢との対応関係を、取出し対象の物品Bの存在する単位空間におけるケース奥行方向視での物品Bの位置及び姿勢とケース奥行方向視での吸着支持部40の位置及び姿勢との対応関係に変換し、当該変換した対応関係に基づいて、取出し対象の物品Bに対する吸着支持部40のケース奥行方向視での位置及び姿勢を導出するように構成されている。   Further, when taking out the article B existing in a unit space other than the reference space among the plurality of unit spaces, the control unit H takes the position and posture of the article B in the case depth direction view in the reference space and the case depth direction view. The relationship between the position and orientation of the suction support unit 40 at the position of the suction support unit 40 in terms of the position and orientation of the article B in the unit depth direction and the case depth direction view in the unit space where the article B to be taken out exists. The position and orientation of the suction support portion 40 with respect to the article B to be taken out are derived based on the converted correspondence relationship. .

Also, a movable body provided at the upper part of the picking area and movable along rails perpendicular to each other along a horizontal plane, and a support shaft that is supported by the movable body and can be moved up and down and rotated along the axis. It is good also as a structure which attaches the adsorption | suction support part 40 to the lower end of a support shaft.

(3)上記実施形態では、吸着支持部40に計7つの第1吸着ノズル42と1つの第2吸着ノズル43とを備える構成としたが、第1吸着ノズル42を8つ以上又は6つ以下としてもよいし、第2吸着ノズル43を2つ以上備える構成としてもよい。すなわち、取出し対象の物品に対して吸着作用するときの姿勢において支持台座41の存在範囲外方に吸着ノズルNが逸脱しないように構成する限りにおいて、吸着ノズルの個数は変更可能である。 (3) In the above embodiment, the suction support unit 40 includes a total of seven first suction nozzles 42 and one second suction nozzle 43.
