And a control device for controlling the operation of the article transport device, and the transfer device places and supports the article. A transfer support unit; and an exit / retreat operation unit for moving the transfer support unit in the longitudinal direction of the shelf. The article transporting device operates to move the transfer support unit in the vertical direction. An elevating operation unit is provided, and the storage unit supports the article at the support position, and the article moving downward from the upper side toward the support position is displaced in the horizontal direction with respect to the support position. The article is brought into contact with the support position while the article is in contact A moving process for moving the transfer device to a stop position with respect to the storage unit in a state in which the control device places and supports an article on the transfer support unit, and the transfer support. And then moving the transfer support portion downward to lower the article to the support position, and then moving the transfer support portion in the shelf front-rear direction. The apparatus is configured to control the operation of the article transporting device so as to execute a storing process for retreating to the article transporting device side. The first feature of the transfer device is that the transfer device is the transfer device. A holding part that holds the position of the article supported by the mounting support part in the horizontal direction, and a holding state that holds the position of the article and a holding release state that releases the holding of the article can be switched. A holding state switching unit, and the control device However, in the moving process, the operation of the article transporting device is controlled so as to move the article transporting device in the lateral width direction of the shelf while the holding unit is switched to the holding state. After starting the projecting movement of the transfer support unit and before lowering the transfer support unit to lower the article to a guide start height higher than the support position, the holding unit is moved from the holding state to the holding unit. The switch is configured to control the operation of the article conveying device to switch to the holding release state, and the article includes a rod- like shaft portion protruding from the article body on both sides in the axial direction of the shaft portion, and the storage The support portion is configured to support the article at the support position in a state where the outer peripheral surfaces of both end portions of the shaft portion are placed and supported, and the guide portion moves downward from the upper side toward the support position. Before the goods to be The article is configured to contact the end of the shaft portion and guide the article to the support position when the position is displaced in the horizontal direction with respect to the support position .

すなわち、移載装置が、移載用支持部に支持されている物品の水平方向での位置を保持する保持部と、保持部を物品の位置を保持する保持状態と物品に対する保持を解除する保持解除状態とに切換自在な保持状態切換部と、を備えているため、移動処理において保持部を保持状態に切り換えた状態で物品搬送装置を棚横幅方向に移動させることで、物品を安定よく搬送することができる。   That is, the transfer device holds the horizontal position of the article supported by the transfer support section, the holding state that holds the position of the article, and the holding that releases the article. Since the holding state switching unit that can be switched to the released state is provided, the article conveying device is moved in the horizontal direction of the shelf while the holding unit is switched to the holding state in the moving process, so that the article can be stably conveyed. can do.

また、収納処理において移載用支持部の突出移動を開始した後で且つ移載用支持部を下降移動させて物品が支持位置より高い案内開始高さまで下降する前に、保持部を保持状態から保持解除状態に切り換えるため、物品が案内部による案内が開始される高さ以上に案内開始高さを設定しておくことで、保持状態で物品が案内部に接触しなくなるため、案内部にて物品を水平方向に移動させて支持位置に適切に位置させる易くなる。
このように、安定よく物品を搬送することができながら物品を収納部に移載するときに物品を支持位置に適切に位置させ易い物品搬送設備を提供することができるに至った。
In addition, after starting the protruding movement of the transfer support portion in the storage process and before the article is lowered to the guide start height higher than the support position by moving the transfer support portion downward, the holding portion is moved from the holding state. In order to switch to the holding release state, by setting the guidance start height higher than the height at which the article is guided by the guide unit, the article will not contact the guide unit in the holding state. It becomes easy to move the article in the horizontal direction so as to be appropriately positioned at the support position.
In this way, it has become possible to provide an article transport facility that can easily position an article appropriately at a support position when the article is transferred to the storage unit while the article can be stably conveyed.

また、物品における棒状の軸部を移載用支持部にて載置支持するため、物品が移載用支持部上で揺れ動く又は軸部の軸心方向に沿ってずれ易く、移載用支持体上で物品が移動し易い状態となっているが、保持部にて物品を保持することで物品搬送装置にて物品を安定よく搬送することができる。
また、案内部が軸部の端部に接触して物品を支持位置に案内するため、物品における軸部に支持されている物品本体が案内部に接触することによる破損を未然に防止することができる。
In addition , since the rod-shaped shaft portion of the article is placed and supported by the transfer support portion, the article easily swings on the transfer support portion or easily shifts along the axial direction of the shaft portion, and the transfer support body. Although the article is in a state of being easily moved, the article can be stably conveyed by the article conveying apparatus by holding the article with the holding unit.
Further, since the guide portion contacts the end portion of the shaft portion to guide the article to the support position, it is possible to prevent damage caused by the article main body supported by the shaft portion of the article contacting the guide portion. it can.

本発明にかかる物品搬送設備の第特徴構成は、第特徴構成において、前記軸部が、円筒形状に形成され、前記移載用支持部が、互いに遠近移動自在で且つ前記軸部の端部に挿入させて前記軸部の内面に接当する状態で前記軸部を各別に載置支持する一対の移載用支持体にて構成され、前記移載装置が、前記一対の移載用支持体を前記軸部の軸心方向の長さより狭い支持用間隔に互いに接近移動させた接近状態及び前記一対の移載用支持体を前記軸部の軸心方向の長さより広い開放用間隔に互いを離間移動させた離間状態に切り換え自在な切換操作部を備えて構成されている点にある。 According to a second characteristic configuration of the article conveying facility according to the present invention, in the first characteristic configuration, the shaft portion is formed in a cylindrical shape, and the transfer support portions are movable to and away from each other, and the end of the shaft portion. And a pair of transfer supports for mounting and supporting the shaft portions separately in a state where the shaft portions are in contact with the inner surface of the shaft portions, and the transfer device is used for the pair of transfer operations. An approaching state in which the support members are moved closer to each other at a support interval narrower than the axial length of the shaft portion, and the pair of transfer support bodies at an opening interval wider than the axial length of the shaft portion. It is in the point which is provided with the change operation part which can be changed to the separation state which moved apart mutually.

すなわち、一対の移載用支持体を支持用間隔に互いに接近移動させて接近状態に切り換えることにより、一対の移載用支持体を軸部の両端部に挿入させることができる。そして、このように一対の移載用支持体を軸部の両端部に挿入して、その挿入した一対の移載用支持体にて軸部の内面を載置支持することで、軸部の物品本体から突出している部分における外周面については、収納用支持部にて載置支持するためだけに用いることができ、軸部の物品本体からの突出量が少なくても、軸部を移載用支持部にて載置支持しながら収納用支持部上に降ろし易くなる。
また、軸部の物品本体からの突出量を少なくてよいため、物品を軸心方向にコンパクトに構成することができる。そのため、物品を収納する収納部を物品の軸心方向に小さくでき、物品収納棚の小型化及び収納効率の向上を図ることができる。
That is, the pair of transfer supports can be inserted into both ends of the shaft portion by moving the pair of transfer supports closer to each other at the support interval and switching them to the close state. And by inserting the pair of transfer supports into both ends of the shaft portion in this way and mounting and supporting the inner surface of the shaft portion with the inserted pair of transfer supports, the shaft portion The outer peripheral surface of the portion protruding from the article body can be used only for placing and supporting the storage support portion, and the shaft portion is transferred even if the amount of protrusion of the shaft portion from the article body is small. It becomes easy to lower on the support part for storage while being placed and supported by the support part for use.
Further, since the protruding amount of the shaft portion from the article main body may be small, the article can be configured compactly in the axial direction. Therefore, the storage part for storing the articles can be reduced in the axial direction of the articles, and the article storage shelf can be downsized and the storage efficiency can be improved.

本発明にかかる物品搬送設備の第特徴構成は、第特徴構成において、前記保持部が、前記一対の移載用支持体と一体的に移動する一対の挟持体にて構成されて、前記一対の挟持体にて前記軸部をその軸心方向に挟持して物品の水平方向での位置を保持するように構成され、前記保持状態切換部が、前記切換操作部に兼用され、前記一対の移載用支持体と前記一対の挟持体とが、前記一対の移載用支持体を前記接近状態に切り換えることで前記一対の挟持体にて前記軸部を軸心方向に挟持して前記保持部が前記保持状態に切り換えられ、前記一対の移載用支持体を前記離間状態に切り換える又は前記一対の移載用支持体を前記接近状態と前記離間状態との間で且つ前記軸部の両端部に対する挿入が維持された中間状態に切り換えることで、前記一対の挟持体による前記軸部に対する挟持が解除されて前記保持部が前記保持解除状態に切り換えられる状態で設けられ、前記制御装置が、前記収納処理において、前記一対の移載用支持体の突出移動を開始した後で且つ前記一対の移載用支持体を下降移動させて物品が前記案内開始高さまで下降する前に、前記一対の移載用支持体を前記接近状態から前記離間状態に向けて切り換えを開始し、前記一対の移載用支持体を前記接近状態と前記離間状態との間で且つ前記支持用間隔を維持した中間状態で物品を支持位置まで下降させ、物品が前記支持位置まで下降した後に前記一対の移載用支持体を離間状態に切り換えるべく、前記物品搬送装置の作動を制御するように構成されている点にある。 According to a third feature configuration of the article transport facility according to the present invention, in the second feature configuration, the holding unit includes a pair of holding bodies that move integrally with the pair of transfer supports, The shaft portion is sandwiched in the axial direction by a pair of sandwiching bodies to hold the position of the article in the horizontal direction, and the holding state switching unit is also used as the switching operation unit, The transfer support body and the pair of sandwiching bodies are configured to sandwich the shaft portion in the axial direction between the pair of sandwiching bodies by switching the pair of transfer support bodies to the approaching state. The holding unit is switched to the holding state, and the pair of transfer supports are switched to the separated state, or the pair of transfer supports are switched between the approaching state and the separated state, and the shaft portion By switching to an intermediate state where insertion to both ends is maintained, The holding of the shaft portion by the pair of holding members is released and the holding portion is switched to the holding release state, and the control device is provided with the pair of transfer supports in the storing process. After the projecting movement is started and before the article is lowered to the guide start height by moving the pair of transfer supports downward, the pair of transfer supports is moved from the approaching state to the separated state. Switching is started, and the pair of transfer supports is lowered to the support position between the approaching state and the separated state and in the intermediate state maintaining the support interval, and the article is supported by the support. In order to switch the pair of transfer supports to the separated state after descending to the position, the operation of the article conveying device is controlled.

すなわち、移載用支持体と挟持体とを一体的に設けるとともに、この移載用支持体と挟持体との組を一対設けることで、保持状態切換部にて一対の移載用支持体の遠近移動と一対の挟持体の遠近移動とをまとめて行うことができる。そのため、保持状態切換部を切換操作部に兼用することができ、一対の移載用支持体と一対の挟持体とを遠近移動させる構成の簡素化を図ることができる。   That is, the transfer support body and the sandwiching body are integrally provided, and a pair of the transfer support body and the sandwiching body is provided so that the holding state switching unit The perspective movement and the pair of holding bodies can be collectively moved. Therefore, the holding state switching unit can also be used as the switching operation unit, and the configuration for moving the pair of transfer supports and the pair of holding members in the near and far directions can be simplified.

また、収納処理において、一対の移載用支持体の突出移動を開始した後で且つ一対の移載用支持体を下降移動させて物品が案内開始高さまで下降する前に、一対の移載用支持体を接近状態から離間状態に向けて切り換えを開始することで、一対の挟持体による軸部に対する挟持が解除されて、保持部が保持解除状態に切り換えられる。また、このように一対の移載用支持体を離間状態に向けて切り換えた後、物品が支持位置まで下降する間は、一対の移載用支持体は中間状態に維持される。
そのため、案内開始高さまで物品が下降したときは、一対の挟持体による軸部に対する挟持は解除されつつも、物品は一対の移載用支持体にて支持されているため、一対の挟持体にて軸部を挾持した状態で物品が案内部に接触することを回避しながら、物品を一対の移載用支持体にて支持した状態で物品を支持位置まで降ろすことができ、物品を支持位置まで適切に搬送することができる。
Further, in the storing process, after the pair of transfer supports are started to protrude and before the article is lowered to the guide start height by moving the pair of transfer supports downward. By starting the switching from the approaching state to the separation state, the holding of the shaft portion by the pair of holding members is released, and the holding unit is switched to the holding release state. In addition, after the pair of transfer supports are switched to the separated state in this way, the pair of transfer supports is maintained in the intermediate state while the article is lowered to the support position.
Therefore, when the article is lowered to the guidance start height, the article is supported by the pair of transfer support bodies while the sandwiching of the shaft portion by the pair of sandwiching bodies is released, but the pair of sandwiching bodies The article can be lowered to the support position while the article is supported by the pair of transfer supports while avoiding the article from coming into contact with the guide portion while holding the shaft portion. Can be properly conveyed.

本発明にかかる物品搬送設備の第特徴構成は、第特徴構成において、前記制御装置が、前記収納処理において、前記一対の移載用支持体の下降移動を開始した後で且つ前記一対の移載用支持体を下降移動させて物品が前記案内開始高さまで下降する前に、前記一対の移載用支持体を前記中間状態に切り換えるべく、前記物品搬送装置の作動を制御するように構成されている点にある。 According to a fourth characteristic configuration of the article conveying facility according to the present invention, in the third characteristic configuration, after the control device starts a downward movement of the pair of transfer supports in the storage process, and The operation of the article conveying device is controlled so that the pair of transfer supports are switched to the intermediate state before the transfer supports are moved down and the articles are lowered to the guide start height. It is in the point.

すなわち、収納処理において、一対の移載用支持体を突出移動させている間及び一対の移載用支持体を下降移動させて物品を案内開始高さに下降させる前までは、一対の移載用支持体が接近状態となっており、一対の挟持体にて軸部が挟持されて物品が保持されている。そのため、移載装置にて収納部に収納するべく一対の移載用支持体を突出移動のとき及び下降移動させる初期段階のときに、物品を安定させた状態で一対の移載用支持体を移動させることができる。   That is, in the storage process, the pair of transfer supports is moved while the pair of transfer supports are projectingly moved and before the pair of transfer supports are moved downward to lower the article to the guide start height. The supporting body is in an approaching state, and the shaft portion is sandwiched between the pair of sandwiching bodies to hold the article. For this reason, the pair of transfer supports are placed in a state in which the article is stabilized in the initial stage of projecting and moving down the pair of transfer supports to be stored in the storage unit by the transfer device. Can be moved.

本発明にかかる物品搬送設備の第特徴構成は、第特徴構成において、前記制御装置が、前記収納処理において、前記軸部の下端が前記案内部の上下幅内に位置する高さで前記一対の移載用支持体を前記中間状態に切り換えるべく、前記物品搬送装置の作動を制御するように構成されている点にある。 According to a fifth characteristic configuration of the article conveying facility according to the present invention, in the fourth characteristic configuration, the control device has a height at which a lower end of the shaft portion is positioned within a vertical width of the guide portion in the storing process. In order to switch the pair of transfer supports to the intermediate state, the operation of the article transporting device is controlled.

すなわち、軸部の下端が案内部の上下幅内に位置する高さで、一対の移載用支持体を互いに離間移動させて中間状態に切り換えるため、離間移動する一対の移載用支持体の一方に載った状態でその一方の移載用支持体とともに軸部が軸心方向に移動したとしても、軸部の端部が案内部に接触することで軸部の移動を規制することができる。
そのため、軸心方向に移動した軸部が案内部の上端に乗り上げることを防止することができ、物品を適切に支持位置に降ろすことができる。
That is, since the lower end of the shaft portion is at a height located within the vertical width of the guide portion, the pair of transfer supports are moved away from each other and switched to the intermediate state. Even if the shaft portion moves in the axial direction together with the transfer support body on the one side, the movement of the shaft portion can be restricted by the end portion of the shaft portion coming into contact with the guide portion. .
Therefore, it is possible to prevent the shaft portion moved in the axial direction from riding on the upper end of the guide portion, and the article can be appropriately lowered to the support position.

本発明にかかる物品搬送設備の第特徴構成は、第又は第特徴構成において、前記収納用支持部に対する前記一対の移載用支持体の高さを検出する検出装置が設けられ、前記制御装置が、前記検出装置の検出情報に基づいて、前記一対の移載用支持体を前記中間状態に切り換えるべく、前記物品搬送装置の作動を制御するように構成されている点にある。 A sixth feature configuration of the article transport facility according to the present invention is the fourth or fifth feature configuration, wherein a detection device that detects the height of the pair of transfer supports relative to the storage support portion is provided, The control device is configured to control the operation of the article conveying device to switch the pair of transfer supports to the intermediate state based on detection information of the detection device.

すなわち、物品の移載対象となる収納用支持部に対する一対の移載用支持体の高さを検出装置にて検出し、その検出情報に基づいて一対の移載用支持体を中間状態に切り換える。そのため、物品収納棚の据付誤差等により収納用支持部の高さが上下方向にずれていたとしても、実際の収納用支持部の高さに対応した高さで一対の移載用支持体を中間状態に切り換えることができ、適切な高さで一対の移載用支持体を中間状態に切り換えることができる。   In other words, the height of the pair of transfer supports with respect to the storage support portion to be transferred is detected by the detection device, and the pair of transfer supports is switched to the intermediate state based on the detection information. .

次に、移載装置4について説明を加える。
図4に示すように、昇降台17は、前後方向視で矩形状に枠組形成されており、その矩形状の昇降台17の上部に吊下げられる形態で移載装置4が支持されている。
図4〜図6に示すように、移載装置4には、輪状の伝動ベルト24を回転駆動させる遠近用モータ25と、伝動ベルト24に連結された一対の移動枠26と、この一対の移動枠26の夫々の下端部に連結されたフォーク装置27と、が設けられている。一対の移動枠26は、伝動ベルト24が回動するに伴って棚横幅方向に互いに異なる方向に移動するように伝動ベルト24に連結されている。
Next, the transfer device 4 will be described.
As shown in FIG. 4, the lifting platform 17 is formed in a rectangular frame when viewed in the front-rear direction, and the transfer device 4 is supported in a form suspended from the upper portion of the rectangular lifting platform 17.
As shown in FIGS. 4 to 6, the transfer device 4 includes a distance motor 25 that rotationally drives a ring-shaped transmission belt 24, a pair of moving frames 26 coupled to the transmission belt 24, and the pair of movements. And a fork device 27 connected to each lower end portion of the frame 26. The pair of moving frames 26 are connected to the transmission belt 24 so as to move in different directions in the lateral width direction of the shelf as the transmission belt 24 rotates.

一対の移動枠26は、伝動ベルト24から下方に伸びる状態で設けられており、一対の移動枠26の夫々の下端部に、先端フォーク部27aを棚前後方向に出退移動する状態でフォーク装置27が連結されている。
そして、一対のフォーク装置27の先端フォーク部27a夫々における出退方向(棚前後方向)の中間部には、先端フォーク部27aの下端から下方側に突出する状態で挟持体29が設けられている。また、一対の挟持体29の夫々の下端部には、挟持体29から棚横幅方向の収納部内方側に突出する状態で移載用支持体28が設けられている。
The pair of moving frames 26 are provided so as to extend downward from the transmission belt 24, and the fork device 27a is moved in the front-rear direction of the shelf at the lower end of each of the pair of moving frames 26. 27 are connected.
And the clamping body 29 is provided in the state which protrudes below from the lower end of the front-end fork part 27a in the intermediate part of the withdrawing / withdrawing direction (shelf front-back direction) in each front-end fork part 27a of a pair of fork devices 27. . In addition, a transfer support 28 is provided at a lower end portion of each of the pair of sandwiching bodies 29 so as to protrude from the sandwiching body 29 toward the inside of the storage unit in the lateral width direction of the shelf.

図7に示すように、一対の移載用支持体28の夫々は、その上下方向及び棚前後方向での大きさが、軸部aの内径より小さく形成されており、移載用支持体28を軸部aの端部に挿入させて軸部aの内面に接当する状態で軸部aを各別に載置支持するように構成されている。   As shown in FIG. 7, each of the pair of transfer supports 28 has a size in the vertical direction and the shelf front-rear direction that is smaller than the inner diameter of the shaft portion a. Is inserted into the end portion of the shaft portion a so that the shaft portion a is placed and supported separately in contact with the inner surface of the shaft portion a.

図4に示すように、移載用支持体28と挟持体29とを連結した状態で設けることで、棚横幅方向で同じ側に位置する移載用支持体28と挟持体29とが、棚横幅方向に一体的に移動するように構成されている。そして、図4に仮想線で示すように、遠近用モータ25の作動により一対のフォーク装置27を棚横幅方向に互いに接近移動させることで、一対の移載用支持体28も互いに近接移動するとともに一対の挟持体29も互いに近接移動するように構成されている。また、図4に実線で示すように、遠近用モータ25の作動により一対のフォーク装置27を棚横幅方向に互いに離間移動させることで、一対の移載用支持体28も互いに離間移動するとともに一対の挟持体29も互いに離間移動するように構成されている。   As shown in FIG. 4, by providing the transfer support body 28 and the sandwiching body 29 in a connected state, the transfer support body 28 and the sandwiching body 29 located on the same side in the shelf lateral width direction It is configured to move integrally in the lateral width direction. Then, as shown by phantom lines in FIG. 4, the pair of fork devices 27 are moved closer to each other in the horizontal direction of the shelf by the operation of the distance motor 25, so that the pair of transfer supports 28 move closer together. The pair of sandwiching bodies 29 are also configured to move close to each other. Further, as shown by a solid line in FIG. 4, the pair of fork devices 27 are moved away from each other in the horizontal direction of the shelf by the operation of the perspective motor 25, so that the pair of transfer supports 28 are moved away from each other and The sandwiching bodies 29 are also configured to move away from each other.

図8〜図11に示すように、一対の移載用支持体28は、遠近用モータ25にて移動させることで、一対の移載用支持体28を軸部aの軸心方向の長さより狭い支持用間隔に互いに接近移動させた接近状態(図10及び図11(a)(b)参照)、一対の移載用支持体28を軸部aの軸心方向の長さより広い開放用間隔に互いに離間移動させた離間状態(図8及び図12(f)参照)、及び、一対の移載用支持体28を接近状態と離間状態との間の状態で且つ一対の移載用支持体28の間隔が支持用間隔に維持された中間状態(図9、図11(c)及び図12(d)(e)参照)に切り換え自在に構成されている。
尚、中間状態での支持用間隔は、接近状態での支持用間隔より広く、離間状態の開放用間隔より狭い間隔となっている。
As shown in FIGS. 8 to 11, the pair of transfer supports 28 are moved by the distance motor 25 so that the pair of transfer supports 28 is longer than the axial length of the shaft portion a. An approaching state in which they are moved closer to each other with a narrow support interval (see FIGS. 10 and 11A and 11B), the pair of transfer supports 28 are wider than the axial length of the shaft portion a. And a pair of transfer supports in a separated state (see FIGS. 8 and 12 (f)) and a pair of transfer supports 28 between an approaching state and a separated state. It is configured to be switchable to an intermediate state (see FIGS. 9, 11 (c), 12 (d) and 12 (e)) in which the interval 28 is maintained at the support interval.
Note that the support interval in the intermediate state is wider than the support interval in the close state and narrower than the open interval in the separated state.

つまり、一対の移載用支持体28を近接状態又は中間状態に切り換えた状態では、一対の移載用支持体28の間隔が軸部aの長さより狭くなり、一対の移載用支持体28を軸部aの両端部に挿入させて一対の移載用支持体28にてロール体1を支持することができるようになっている。また、一対の移載用支持体28を離間状態に切り換えた状態では、一対の移載用支持体28の間隔が軸部aの長さより広くなり、一対の移載用支持体28の両方を軸部aから抜出させることができるようになっている。   That is, in a state where the pair of transfer supports 28 is switched to the close state or the intermediate state, the distance between the pair of transfer supports 28 is narrower than the length of the shaft portion a, and the pair of transfer supports 28. Is inserted into both ends of the shaft portion a, and the roll body 1 can be supported by the pair of transfer supports 28. Further, in a state where the pair of transfer supports 28 are switched to the separated state, the distance between the pair of transfer supports 28 is wider than the length of the shaft portion a, and both of the pair of transfer supports 28 are connected. It can be extracted from the shaft part a.

そして、保持部21は、一対の移載用支持体28を接近状態に切り換えることで一対の挟持体29にて軸部aを軸心方向に挾持して保持部21が保持状態に切り換えられる。また、一対の移載用支持体28を接近状態から離間状態に向けて切り換えを開始することで、一対の挟持体29による軸部aに対する挟持が解除されて保持部21が保持解除状態に切り換えられる。
ちなみに、一対の移載用支持体28を中間状態に切り換えた状態では、一対の移載用支持体28の軸部aへの挿入量の合計が、一対の挟持体29の軸部aとの間隔の合計より大きくなっており、ロール体1が軸心方向に移動したとしてもその移動が挟持体29にて規制されることで軸部aが移載用支持体28から抜けないようになっている。
The holding portion 21 switches the pair of transfer supports 28 to the approaching state, thereby holding the shaft portion a in the axial direction by the pair of sandwiching bodies 29 and switching the holding portion 21 to the holding state. Further, by starting switching of the pair of transfer supports 28 from the approaching state to the separating state, the paired holding bodies 29 are released from the holding of the shaft portion a and the holding unit 21 is switched to the holding release state. It is done.
Incidentally, in a state where the pair of transfer support bodies 28 is switched to the intermediate state, the total amount of insertion of the pair of transfer support bodies 28 into the shaft portion a is the same as the shaft portion a of the pair of sandwiching bodies 29. Even if the roll body 1 moves in the axial direction, the movement of the roll body 1 is restricted by the sandwiching body 29 so that the shaft portion a does not come off from the transfer support body 28. ing.

一対の移載用支持体28は、互いに遠近移動自在で且つ軸部aの端部に挿入させて軸部aの内面に接当する状態で軸部aを各別に載置支持するように構成されており、これら一対の移載用支持体28にて移載用支持部19が構成されている。
また、遠近用モータ25は、保持部21をロール体1の位置を保持する保持状態とロール体1に対する保持を解除する保持解除状態とに切換自在な保持状態切換部22に相当し、この保持状態切換部22は、一対の移載用支持体28を互いに接近移動させて軸部aの両端部に挿入させた接近状態及び一対の移載用支持体28を互いに離間移動させて一対の移載用支持体28を軸部aの両端部から抜出させた離間状態に切り換え自在な切換操作部に兼用されている。
The pair of transfer supports 28 is configured to be mounted on and supported by each of the shaft portions a in a state in which the pair of transfer supports 28 can be moved to and away from each other and are in contact with the inner surface of the shaft portion a. The pair of transfer supports 28 constitutes a transfer support portion 19.
The perspective motor 25 corresponds to a holding state switching unit 22 that can be switched between a holding state in which the holding unit 21 holds the position of the roll body 1 and a holding release state in which the holding of the roll body 1 is released. The state switching unit 22 moves the pair of transfer supports 28 closer to each other and inserts them into both ends of the shaft portion a, and moves the pair of transfer supports 28 away from each other to move the pair of transfer supports 28 apart from each other. The mounting support 28 is also used as a switching operation unit that can be switched to a separated state in which the mounting support 28 is pulled out from both ends of the shaft portion a.

そして、保持部21は、一対の移載用支持体28と一体的に移動する一対の挟持体29にて構成されて、一対の挟持体29にて軸部aをその軸心方向に挾持してロール体1の水平方向での位置を保持するように構成されている。
また、一対の挟持体29は、フォーク装置27の作動により棚前後方向に移動するように構成されており、このフォーク装置27が出退操作部20に相当する。また、一対の移載用支持体28は、昇降台17の昇降移動により上下方向に移動するように構成されており、この昇降台17が、スタッカークレーン5に備えられて移載用支持部19を上下方向に移動操作する昇降操作部に相当する。
The holding portion 21 is composed of a pair of holding bodies 29 that move integrally with the pair of transfer support bodies 28, and holds the shaft portion a in the axial direction with the pair of holding bodies 29. The roll body 1 is configured to hold the position in the horizontal direction.
Further, the pair of sandwiching bodies 29 are configured to move in the longitudinal direction of the shelf by the operation of the fork device 27, and the fork device 27 corresponds to the exit / retreat operation unit 20. Further, the pair of transfer supports 28 are configured to move in the vertical direction by the up-and-down movement of the lifting platform 17, and the lifting platform 17 is provided in the stacker crane 5 and is mounted on the transfer support unit 19. This corresponds to an elevating operation unit that moves and moves up and down.

図4〜図6に示すように、昇降台17には、移載用支持部19から落下したロール体1を昇降台17上で受け止める受け止め部31が設けられている。
受け止め部31は、フォーク装置27を棚前後方向のスタッカークレーン側に引退させた状態で移載用支持部19にて支持されているロール体1(以下、走行位置のロール体1と称する)の直下に設けられている。
As shown in FIGS. 4 to 6, the lifting platform 17 is provided with a receiving portion 31 that receives the roll body 1 dropped from the transfer support portion 19 on the lifting platform 17.
The receiving part 31 is a roll body 1 (hereinafter referred to as a roll body 1 in a traveling position) supported by the transfer support part 19 in a state where the fork device 27 is retracted to the stacker crane side in the longitudinal direction of the shelf. It is provided directly below.

受け止め部31は、上下方向及び棚前後方向に沿う姿勢の一対の板状体31aと、その一対の板状体31aに亘って架設された複数本の受け止め棒31bと、で構成されている。
一対の板状体31aは、シート材bの棚横幅方向(軸心方向)の幅より広い間隔で棚横幅方向に間隔を隔てた状態で設けられている。複数本の受け止め棒31bは、走行位置のロール体1の軸心の直下に位置する受け止め棒31bを中心に、棚前後方向の前方側及び後方側に位置する受け止め棒31bほど高い位置となるように棚横幅方向視で円弧状に配設されている。
そのため、一対の移載用支持体28から落下したロール体1は直下に位置する受け止め部31にて受け止められるが、中心の受け止め棒31bに接触した後に受け止め部31上で棚前後方向に転がって、ロール体1の平面視での位置が走行位置から棚前後方向に移動するようになっている。
The receiving portion 31 includes a pair of plate-like bodies 31a in a posture along the vertical direction and the shelf front-rear direction, and a plurality of receiving rods 31b installed across the pair of plate-like bodies 31a.
The pair of plate-like bodies 31a is provided in a state where the sheet material b is spaced apart in the shelf lateral width direction at an interval wider than the width in the shelf lateral width direction (axial direction). The plurality of receiving rods 31b are positioned so that the receiving rods 31b positioned on the front side and the rear side in the front-rear direction of the shelf are positioned higher with the receiving rod 31b positioned directly below the axis of the roll body 1 in the traveling position as the center. Are arranged in an arc shape when viewed in the width direction of the shelf.
Therefore, the roll body 1 dropped from the pair of transfer supports 28 is received by the receiving portion 31 positioned immediately below, but after contacting the central receiving rod 31b, it rolls in the longitudinal direction of the shelf on the receiving portion 31. The position of the roll body 1 in plan view is moved in the longitudinal direction of the shelf from the traveling position.

昇降台17には、一対の移載用支持体28からロール体1が落下したことを検出する落下検出センサ32(図16参照)が設けられている。この落下検出センサ32は、ロール体1が走行位置から棚前後方向に移動したことを検出するように構成されており、具体的には、走行位置に位置するロール体1の棚前後方向の両側に投光し、ロール体1が受け止め部31上に落下して受け止め部31上でロール体1が棚前後方向に移動してロール体1にて投光が遮断されることで、ロール体1の落下を検出するように構成されている。   The elevator 17 is provided with a drop detection sensor 32 (see FIG. 16) that detects that the roll body 1 has fallen from the pair of transfer supports 28. The drop detection sensor 32 is configured to detect that the roll body 1 has moved in the longitudinal direction of the shelf from the traveling position. Specifically, both sides of the roll body 1 located in the traveling position in the longitudinal direction of the shelf. The roll body 1 falls onto the receiving portion 31 and the roll body 1 moves on the receiving portion 31 in the longitudinal direction of the shelf so that the light is blocked by the roll body 1. It is configured to detect the fall of the.

落下検出センサ32の検出情報が制御装置Hに入力されており、制御装置Hは、落下検出センサ32にてロール体1の落下を示す検出情報が入力されたときは、その落下検出センサ32の検出情報に基づいてスタッカークレーン5を非常停止させるべく、スタッカークレーン5の作動を制御するように構成されている。   The detection information of the fall detection sensor 32 is input to the control device H. When the detection information indicating the fall of the roll body 1 is input by the fall detection sensor 32, the control device H of the fall detection sensor 32 The operation of the stacker crane 5 is controlled so that the stacker crane 5 is brought to an emergency stop based on the detection information.

また、昇降台17には、収納用支持部12に対する一対の移載用支持体28の高さを検出する検出装置としての昇降位置検出センサ33(図16参照)が設けられている。
この昇降位置検出センサ33は、棚前後方向の収納部側に向けて検出光を投光しており、後述する収納処理において一対の移載用支持体28の下降移動を開始するときは、昇降位置検出センサ33の検出光が腕木10に投射されて腕木10の存在が検出され、一対の移載用支持体28が下降移動の途中で一対の移載用支持体28を接近状態から中間状態への切り換えを開始する前に昇降位置検出センサ33の検出光が腕木10から外れて腕木10の存在が検出されなくなるように、昇降位置検出センサ33は昇降台17に設けられている。
このように昇降位置検出センサ33は、腕木10に対する昇降台17の高さを検出することで、間接的に収納用支持部12に対する一対の移載用支持体28の高さを検出するように構成されている。
In addition, the lifting platform 17 is provided with a lifting position detection sensor 33 (see FIG. 16) as a detection device that detects the height of the pair of transfer supports 28 relative to the storage support 12.
The lift position detection sensor 33 projects detection light toward the storage unit in the front-rear direction of the shelf, and when starting the downward movement of the pair of transfer supports 28 in the storage process described later, The detection light of the position detection sensor 33 is projected onto the arm 10 to detect the presence of the arm 10, and the pair of transfer supports 28 are moved from the approaching state to the intermediate state while the pair of transfer supports 28 are moving downward. The elevating position detection sensor 33 is provided on the elevating platform 17 so that the detection light of the elevating position detection sensor 33 deviates from the arm 10 before the start of switching to, and the presence of the arm 10 is not detected.
Thus, the lift position detection sensor 33 detects the height of the pair of transfer supports 28 relative to the storage support 12 by detecting the height of the lift 17 with respect to the arm 10. It is configured.

制御装置Hは、移載装置4を収納部2に対する停止位置に移動させる移動処理と、移載装置4の移載用支持部19にて支持しているロール体1を収納部2に収納する収納処理と、収納部2に収納されているロール体1を移載装置4の移載用支持部19にて支持する状態に取り出す取出処理と、を実行するべく、スタッカークレーン5の作動を制御するように構成されている。   The control device H stores the roll body 1 supported by the moving process of moving the transfer device 4 to the stop position with respect to the storage unit 2 and the transfer support unit 19 of the transfer device 4 in the storage unit 2. The operation of the stacker crane 5 is controlled so as to execute the storage process and the take-out process for taking out the roll body 1 stored in the storage unit 2 to be supported by the transfer support unit 19 of the transfer device 4. Is configured to do.

移動処理では、基準位置からの走行台車15の昇降距離を検出する走行用距離センサ34(図16参照)の検出情報に基づいて、走行用モータ15aの作動により走行台車15を走行移動させて移載装置4を棚横幅方向に沿って移動させ、基準位置からの昇降台17の昇降距離を検出する昇降用距離センサ35(図16参照)の検出情報に基づいて、昇降用モータ17aの作動により昇降台17を昇降移動させて移載装置4を上下方向に移動させて、移載装置4を収納部2に対する停止位置に移動させるべく、スタッカークレーン5の作動が制御される。   In the movement process, based on the detection information of the travel distance sensor 34 (see FIG. 16) that detects the elevation distance of the travel carriage 15 from the reference position, the travel carriage 15 is moved and moved by the operation of the travel motor 15a. By moving the mounting device 4 along the horizontal width direction of the shelf and operating the lifting motor 17a based on the detection information of the lifting distance sensor 35 (see FIG. 16) that detects the lifting distance of the lifting platform 17 from the reference position. The operation of the stacker crane 5 is controlled to move the lifting platform 17 up and down to move the transfer device 4 in the vertical direction and move the transfer device 4 to a stop position with respect to the storage unit 2.

そして、移動処理として、取出処理の後で且つ収納処理の前に実行される収納用の移動処理と、収納処理の後で且つ取出処理の後に実行される取出用の移動処理と、がある。収納用の移動処理では、一対の移載用支持体28にてロール体1を載置支持した状態で、移載装置4を収納部2に対応する収納用停止位置に移動させるようになっている。また、取出用の移動処理では、一対の移載用支持体28にてロール体1を載置支持していない状態で、移載装置4を収納部2に対応する取出用停止位置に移動させるようになっている。
尚、取出用停止位置は、収納用停止位置より設定量高い高さに設定されている。
The movement process includes a storage movement process executed after the take-out process and before the storage process, and a take-out movement process executed after the storage process and after the take-out process. In the storage movement process, the transfer device 4 is moved to the storage stop position corresponding to the storage unit 2 in a state where the roll body 1 is mounted and supported by the pair of transfer supports 28. Yes. Further, in the removal movement process, the transfer device 4 is moved to the removal stop position corresponding to the storage unit 2 in a state where the roll body 1 is not placed and supported by the pair of transfer supports 28. It is like that.
The take-out stop position is set to a height that is higher than the storage stop position by a set amount.

収納処理では、一対の移載用支持体28を棚前後方向の収納部2側に突出移動させ、一対の移載用支持体28を下降移動させてロール体1を支持位置に降ろした後、一対の移載用支持体28を棚前後方向のスタッカークレーン側に引退移動させるべく、スタッカークレーン5の作動が制御される。   In the storage process, the pair of transfer supports 28 are projected and moved toward the storage unit 2 in the front-rear direction of the shelf, and the pair of transfer supports 28 are moved downward to lower the roll body 1 to the support position. The operation of the stacker crane 5 is controlled so that the pair of transfer supports 28 are retreated to the stacker crane side in the longitudinal direction of the shelf.

収納処理を開始するときは、一対の移載用支持体28は接近状態に切り換えられており、収納処理では、一対の移載用支持体28の下降移動を開始した後で且つ軸部aの下端が案内部13の上下幅内に位置する高さで一対の移載用支持体28を接近状態から中間状態に切り換えて、一対の移載用支持体28の下降移動が完了してロール体1が支持位置に降ろされた後で且つ一対の移載用支持体28の引退移動を開始する前に、一対の移載用支持体28を離間状態に切り換えるようになっている。   When the storage process is started, the pair of transfer supports 28 are switched to the approaching state, and in the storage process, after the pair of transfer supports 28 starts to move down and the shaft portion a is moved. The pair of transfer support bodies 28 are switched from the approaching state to the intermediate state at a height where the lower ends are positioned within the vertical width of the guide portion 13, and the pair of transfer support bodies 28 are moved downward to complete the roll body. After 1 is lowered to the support position and before the retraction movement of the pair of transfer supports 28 is started, the pair of transfer supports 28 is switched to the separated state.

つまり、図13に示すように、収納処理では、まず、一対の移載用支持体28を突出移動させる(図11(a)参照)。次に、一対の移載用支持体28の下降移動を開始し、その一対の移載用支持体28の下降移動途中において、昇降位置検出センサ33の検出情報に基づいてロール体1の軸部aの下端が案内部13の上端より下方に位置する状態で一対の移載用支持体28の中間状態への切り換えを開始し、支持位置より高い案内開始高さにロール体1が下降する前に中間状態への切り換えを完了した後、ロール体1が支持位置に降ろされる(図11(b)(c)、図12(d)(e)参照)。その後、一対の移載用支持体28を離間状態に切り換えた後(図12(f)参照)、一対の移載用支持体28を引退移動させる。
尚、案内開始高さは、走行台車15の停止誤差やフォーク装置27の出退誤差等が生じたときに、収納処理により一対の移載用支持体28を下降させてもロール体1の軸部aが案内部13に接触しない高さに設定されており、案内部13の上下幅内に設定されている。
That is, as shown in FIG. 13, in the storage process, first, the pair of transfer supports 28 are moved to project (see FIG. 11A). Next, the lowering movement of the pair of transfer supports 28 is started, and the shaft portion of the roll body 1 is detected based on the detection information of the elevating position detection sensor 33 during the lowering movement of the pair of transfer supports 28. Switching to the intermediate state of the pair of transfer supports 28 is started in a state where the lower end of a is positioned below the upper end of the guide portion 13, and before the roll body 1 is lowered to a guide start height higher than the support position. Then, after the switching to the intermediate state is completed, the roll body 1 is lowered to the support position (see FIGS. 11B, 11C, 12D, and 12E). Thereafter, after the pair of transfer supports 28 are switched to the separated state (see FIG. 12F), the pair of transfer supports 28 are retreated.
It should be noted that the guidance start height is such that the shaft of the roll body 1 can be moved even if the pair of transfer supports 28 are lowered by the storing process when a stop error of the traveling carriage 15 or an exit / exit error of the fork device 27 occurs. The part a is set to a height that does not contact the guide part 13, and is set within the vertical width of the guide part 13.

取出処理では、一対の移載用支持体28を棚前後方向の収納部側に突出移動させ、一対の移載用支持体28を上昇移動させてロール体1を支持位置から持ち上げた後、一対の移載用支持体28を棚前後方向のスタッカークレーン側に引退移動させるべく、スタッカークレーン5の作動が制御される。   In the take-out process, the pair of transfer supports 28 are projected and moved toward the storage unit in the front-rear direction of the shelf, and the pair of transfer supports 28 are moved upward to lift the roll body 1 from the support position. The operation of the stacker crane 5 is controlled so that the transfer support 28 is retreated to the stacker crane side in the longitudinal direction of the shelf.

取出処理を開始するときは、一対の移載用支持体28は離間状態に切り換えられており、取出処理では、一対の移載用支持体28の棚前後方向の収納部側への突出移動が完了した後、一対の移載用支持体28の上昇移動を開始する前に、一対の移載用支持体28を中間状態に切り換え、一対の移載用支持体28の引退移動が完了した後で且つ移動処理を開始する前に、一対の移載用支持体28を接近状態に切り換えるようになっている。   When the take-out process is started, the pair of transfer supports 28 are switched to the separated state, and in the take-out process, the pair of transfer supports 28 protrude and move toward the storage unit in the front-rear direction of the shelf. After completion, before starting the upward movement of the pair of transfer supports 28, the pair of transfer supports 28 is switched to the intermediate state, and the retraction movement of the pair of transfer supports 28 is completed. And before starting a movement process, a pair of support body 28 for a transfer is switched to an approach state.

つまり、図15に示すように、取出処理では、まず、一対の移載用支持体28を突出移動させる(図14(a)参照)。次に、一対の移載用支持体28を中間状態に切り換えた後、一対の移載用支持体28を上昇移動させる(図14(b)(c)参照)。その後、一対の移載用支持体28を引退移動させ、一対の移載用支持体28を接近状態に切り換える。   That is, as shown in FIG. 15, in the take-out process, first, the pair of transfer supports 28 are moved to project (see FIG. 14A). Next, after the pair of transfer supports 28 are switched to the intermediate state, the pair of transfer supports 28 are moved up (see FIGS. 14B and 14C). Thereafter, the pair of transfer supports 28 are retreated, and the pair of transfer supports 28 are switched to the approaching state.

このように、収納用の移動処理を実行して移載装置4が上下方向や棚横幅方向に移動するとき、及び、収納処理における一対の移載用支持体28を突出移動させるときや一対の移載用支持体28を下降移動させる初期段階では、保持部21にてロール体1が保持されているため、ロール体1を安定よく搬送することができる。また、収納処理における案内部13にて軸部aが案内されるときは、保持部21によるロール体1に対する保持が解除されているため、ロール体1が案内部13に接触することによるロール体1や案内部13の変形を回避することができる。   As described above, when the transfer device 4 is moved in the vertical direction or the horizontal width direction of the shelf by executing the storage movement process, and when the pair of transfer supports 28 in the storage process is projected and moved, In the initial stage in which the transfer support 28 is moved downward, the roll body 1 is held by the holding unit 21, so that the roll body 1 can be stably conveyed. Further, when the shaft portion a is guided by the guide portion 13 in the storage process, the holding of the roll body 1 by the holding portion 21 is released, and thus the roll body by the roll body 1 coming into contact with the guide portion 13. 1 and the deformation | transformation of the guide part 13 can be avoided.

〔別実施形態〕
(1) 上記実施形態では、収納処理における一対の移載用支持体28の下降移動を開始した後で且つ軸部aの下端が案内部13の上下幅内に位置する高さで一対の移載用支持体28を中間状態に切り換え(保持部21を保持解除状態に切り換え)たが、収納処理における一対の移載用支持体28の突出移動を開始した後で且つ一対の移載用支持体28を下降移動させて物品が支持位置より高い案内開始高さまで下降する前に、一対の移載用支持体28を中間状態に切り換えてもよい。
[Another embodiment]
(1) In the above embodiment, the pair of transfer supports 28 at a height at which the lower end of the shaft portion a is located within the vertical width of the guide portion 13 after the downward movement of the pair of transfer supports 28 in the storage process is started. The mounting support 28 is switched to the intermediate state (the holding unit 21 is switched to the holding release state), but after the pair of transfer support bodies 28 starts to move in the storage process, and the pair of transfer supports. The pair of transfer supports 28 may be switched to the intermediate state before the body 28 is moved down and the article is lowered to a guide start height higher than the support position.

つまり、収納処理における一対の移載用支持体28の突出移動中や、収納処理における一対の移載用支持体28の突出移動が完了した後で且つ一対の移載用支持体28の下降移動を開始する前に、一対の移載用支持体28を中間状態に切り換えてもよく、また、収納処理における一対の移載用支持体28の下降移動が開始した後で且つ一対の移載用支持体28を下降移動させて物品が案内開始高さまで下降する前に、一対の移載用支持体28を中間状態に切り換えてもよい。
尚、案内開始高さは、比較的生じ易い小さな誤差のときだけロール体1の軸部aが案内部13に接触しない高さにする等、適宜変更してもよく、少なくとも支持位置より高い高さであればよい。
That is, during the protruding movement of the pair of transfer supports 28 in the storing process, or after the protruding movement of the pair of transfer supports 28 in the storing process is completed, the downward movement of the pair of transfer supports 28 Before starting the pair of transfer supports 28, the pair of transfer supports 28 may be switched to the intermediate state, and after the pair of transfer supports 28 are moved downward in the storing process, the pair of transfer supports 28 are used. The pair of transfer supports 28 may be switched to an intermediate state before the support 28 is moved down to lower the article to the guidance start height.
Note that the guide start height may be changed as appropriate, for example, so that the shaft portion a of the roll body 1 does not contact the guide portion 13 only when a small error that is relatively likely to occur. That's fine.

また、収納処理において一対の移載用支持体28を下降移動させながら、一対の移載用支持体28を接近状態から中間状態に切り換えたが、一対の移載用支持体28の下降移動を一旦中断して下降移動を停止させた状態で、一対の移載用支持体28を接近状態から中間状態に切り換えてもよい。   In addition, while the pair of transfer supports 28 are moved downward in the storage process, the pair of transfer supports 28 are switched from the approaching state to the intermediate state, but the pair of transfer supports 28 are moved downward. The pair of transfer supports 28 may be switched from the approaching state to the intermediate state once interrupted and stopped in the downward movement.

(2) 上記実施形態では、取出処理における一対の移載用支持体28の突出移動が完了した後で且つ一対の移載用支持体28の上昇移動を開始させる前に、一対の移載用支持体28を中間状態に切り換え、一対の移載用支持体28の引退移動が完了した後に、一対の移載用支持体28を接近状態に切り換えたが、取出処理における一対の移載用支持体28の突出移動が完了した後で且つ一対の移載用支持体28の上昇移動を開始させる前に、一対の移載用支持体28を接近状態まで切り換えてもよい。 (2) In the above-described embodiment, the pair of transfer supports 28 are moved after the pair of transfer supports 28 have been protruded and before the upward movement of the pair of transfer supports 28 is started. After the support body 28 is switched to the intermediate state and the retraction movement of the pair of transfer support bodies 28 is completed, the pair of transfer support bodies 28 are switched to the approaching state. After the projecting movement of the body 28 is completed and before the ascending movement of the pair of transfer support bodies 28 is started, the pair of transfer support bodies 28 may be switched to the approaching state.

(3) 上記実施形態では、案内部13を、棚前後方向の傾斜部11bと棚横幅方向の傾斜部11bとを備えて、物品を棚前後方向及び棚横幅方向に案内するように構成したが、案内部13を、棚前後方向の傾斜部11bのみを備えて、物品を棚前後方向にのみ案内するように構成してもよい。 (3) In the said embodiment, although the guide part 13 was provided with the inclination part 11b of a shelf front-back direction and the inclination part 11b of a shelf width direction, it comprised so that articles might be guided to a shelf front-back direction and a shelf width direction. The guide unit 13 may be configured to include only the inclined part 11b in the front-rear direction of the shelf and guide the article only in the front-rear direction of the shelf.

(4) 上記実施形態では、移載用支持体28と挟持体29とを一体的に移動するように構成したが、移載用支持体28と挟持体29とを別体に設けて、一対の移載用支持体28と一対の挟持体29とが別々に移動するように構成してもよい。
また、移載用支持部19を、互いに遠近移動自在で且つ円筒形状の棒状に形成された軸部aの端部に挿入させて軸部aの内面に接当する状態で軸部aを各別に支持する一対の移載用支持体28にて構成したが、移載用支持部19を、中実の棒状に形成された軸部aの外周面を載置支持する一対の載置支持体にて構成してもよく、又は、図17に示すように、物品の底面を載置支持する載置体36aにて構成してもよい
(4) In the above embodiment, the transfer support body 28 and the sandwiching body 29 are configured to move integrally. However, the transfer support body 28 and the sandwiching body 29 are provided separately, and a pair of them is provided. The transfer support body 28 and the pair of sandwiching bodies 29 may be configured to move separately.
Further, the transfer support portion 19 is inserted into the end portion of the shaft portion a formed in the shape of a cylindrical rod that is movable to and away from each other, and the shaft portion a is in contact with the inner surface of the shaft portion a. The pair of transfer supports 28 are separately supported, but the transfer support 19 is mounted on the outer peripheral surface of the shaft portion a formed in a solid bar shape. Alternatively, as shown in FIG. 17, it may be configured by a mounting body 36a for mounting and supporting the bottom surface of the article .

つまり、図17に示すように、スタッカークレーン5の昇降台17に、移載用支持部19としての載置体36aを出退移動自在に備えたフォーク機構36と、保持部21としての一対の挟持部38と、を備え、箱状物品37の底面を載置体36aにて載置支持し、その箱状物品37を一対の挟持部38にて棚横幅方向に挟持するように構成してもよい。
このように構成した場合、箱状物品37を挾持する一対の挟持部38と載置体36aとを一体的に突出移動させた後(図17に仮想線を示す位置)、昇降台17を下降移動させて載置体36aと一対の挟持体29を下降移動させ、その下降移動中に一対の挟持体29を離間移動させるとよい。
That is, as shown in FIG. 17, the fork mechanism 36 provided with the mounting body 36 a as the transfer support portion 19 on the lifting platform 17 of the stacker crane 5 so as to be movable in and out, and the pair of holding portions 21. And holding the bottom of the box-shaped article 37 by the mounting body 36a, and the box-shaped article 37 is sandwiched by the pair of clamping sections 38 in the lateral width direction of the shelf. Also good.
In the case of such a configuration, after the pair of sandwiching portions 38 for holding the box-shaped article 37 and the mounting body 36a are integrally projected and moved (positions indicated by phantom lines in FIG. 17), the lifting platform 17 is lowered. It is preferable to move the mounting body 36a and the pair of holding bodies 29 downward and move the pair of holding bodies 29 apart during the downward movement.

(5) 上記実施形態では、収納処理において、一対の移載用支持体28を下降移動させて物品が案内開始高さまで下降する前に、一対の移載用支持体28の接近状態から中間状態への切り換えを完了させたが、収納処理において、一対の移載用支持体28を下降移動させて物品が下降移動開始高さに下降する前に、一対の移載用支持体28を接近状態から中間状態への切り換えを開始すればよく、一対の移載用支持体28を下降移動させて物品が案内開始高さと支持位置との間に位置する状態で、一対の移載用支持体28の接近状態から中間状態への切り換えを完了させてもよい。
また、収納処理において、一対の移載用支持体28を下降移動させて物品が支持位置まで下降すると同時に一対の移載用支持体28の接近状態から中間状態への切り換えを完了させてもよく、この場合、一対の移載用支持体28の中間状態への切り換えが完了した後、一対の移載用支持体28の離間移動を停止させずに一対の移載用支持体28を離間状態への切り換えを開始させてもよい。
