Description

本発明は、対向して配置される一対の収納棚と、前記一対の収納棚の間に設置された複数の走行レールと、前記走行レールの上を走行する複数の搬送台車と、を備えた自動倉庫に関する。 The present invention includes a pair of storage shelves arranged to face each other, a plurality of traveling rails installed between the pair of storage shelves, and a plurality of transport carts traveling on the traveling rails. Regarding automated warehouses.

かかる自動倉庫の従来例が、特開２０１６−０６０６２４号公報（特許文献１）に記載されている。 A conventional example of such an automated warehouse is described in Japanese Patent Application Laid-Open No. 2016-060624 (Patent Document 1).

特許文献１の自動倉庫は、搬送台車を当該搬送台車が走行する走行経路から取り出す場合、ハンドリフト、フォークリフト、又は搬送台車を搬出するための専用の巻上機等の取出用装置を用いて、自動倉庫の端部から搬送台車を搬送方向に抜き出すようにして、搬送台車を走行レール上から取り出していた。 In the automated warehouse of Patent Document 1, when the transport trolley is taken out from the traveling path on which the transport trolley travels, a hand lift, a forklift, or a take-out device such as a dedicated hoisting machine for carrying out the transport trolley is used. The transport trolley was taken out from the traveling rail by pulling out the transport trolley from the end of the automated warehouse in the transport direction.

しかし、自動倉庫の搬送方向の一方側に、他の設備が設置されている又は壁が設置されていることにより、自動倉庫の搬送方向の一方側に取出用装置を設置するためのスペースが存在しない場合がある。このような場合には、自動倉庫の端部から搬送台車を搬送方向に抜き出すことができない。そのため、搬送台車を走行レール上から下方に取り出すことが求められている。 However, because other equipment or walls are installed on one side of the automated warehouse in the transport direction, there is space for installing the take-out device on one side of the automated warehouse in the transport direction. It may not be. In such a case, the transport trolley cannot be pulled out from the end of the automated warehouse in the transport direction. Therefore, it is required to take out the transport carriage downward from the traveling rail.

そこで、搬送台車を走行レール上から下方に取り出すことが可能な自動倉庫の実現が望まれる。 Therefore, it is desired to realize an automated warehouse in which the transport trolley can be taken out from the traveling rail downward.

上記に鑑みた、自動倉庫の特徴構成は、対向して配置される一対の収納棚と、前記一対の収納棚の間に設置された複数の走行レールと、前記走行レールの上を走行する複数の搬送台車と、を備え、前記一対の収納棚の夫々は、物品を収納する棚部を上下方向に並ぶ状態で複数備え、前記走行レールは、前記棚部の夫々に対応して設置され、前記一対の収納棚の対向方向に直交する方向及び水平方向に沿う方向である搬送方向に延在し、前記複数の走行レールの夫々は、前記対向方向に間隔を空けて設置された一対のレール部を備え、前記複数の搬送台車の夫々は、前記一対のレール部を転動する走行輪を備えている自動倉庫であって、
前記一対の収納棚に跨るように配置された支持部材を、更に備え、前記支持部材は、前記搬送台車を吊り下げる第１吊り下げ装置を支持する第１支持部と、前記搬送台車を吊り下げる第２吊り下げ装置を支持する第２支持部と、を備え、上下方向視で、前記第１支持部は、前記対向方向における前記一対のレール部の中央位置に重なる位置に配置され、前記第２支持部は、前記第１支持部に対して前記対向方向の一方側に配置されている点にある。 In view of the above, the characteristic configuration of the automated warehouse is a pair of storage shelves arranged to face each other, a plurality of traveling rails installed between the pair of storage shelves, and a plurality of traveling rails traveling on the traveling rails. Each of the pair of storage shelves is provided with a plurality of shelves for storing articles arranged in the vertical direction, and the traveling rails are installed corresponding to the respective shelves. The pair of storage shelves extend in the transport direction, which is a direction orthogonal to the facing direction and a direction along the horizontal direction, and each of the plurality of traveling rails is a pair of rails installed at intervals in the facing direction. Each of the plurality of transport shelves is an automated warehouse equipped with a traveling wheel that rolls on the pair of rail portions.
A support member arranged so as to straddle the pair of storage shelves is further provided, and the support member suspends the first support portion for supporting the first suspension device for suspending the transport carriage and the transport carriage. A second support portion for supporting the second suspension device is provided, and the first support portion is arranged at a position overlapping the central position of the pair of rail portions in the opposite direction in a vertical view. The two support portions are located on one side in the direction opposite to the first support portion.

この特徴構成によれば、第１吊り下げ装置及び第２吊り下げ装置により搬送台車を搬送レールから上昇させることができ、このように搬送台車を上昇させた状態で、第１吊り下げ装置により搬送台車を支持している部分の上昇と第２吊り下げ装置により搬送台車を支持している部分の下降との一方又は双方により、搬送台車を回転させて搬送台車を横転姿勢に変更できる。そして、このように搬送台車の姿勢を変更することで、搬送台車は第１吊り下げ装置により横転姿勢で吊り下げられることになるが、第１吊り下げ装置を支持する第１支持部は、一対のレール部の中央位置に重なる位置に配置されているため、第１吊り下げ装置により吊り下げられた搬送台車は、上下方向視で、対向方向における一対のレール部の中央位置に重なる位置となる。従って、搬送台車を一対のレール部の間を通して下方に取り出すことが容易となっている。 According to this characteristic configuration, the transport carriage can be lifted from the transport rail by the first suspension device and the second suspension device, and the transport carriage is transported by the first suspension device in the state of being lifted in this way. The transport trolley can be rotated to change the transport trolley to a rollover posture by raising the portion supporting the trolley and lowering the portion supporting the transport trolley by the second suspension device. By changing the posture of the transport carriage in this way, the transport carriage is suspended in a rollover posture by the first suspension device, but the first support portions that support the first suspension device are paired. Since it is arranged at a position overlapping the center position of the rail portion of the above, the transport carriage suspended by the first suspension device is located at a position overlapping the center position of the pair of rail portions in the opposite direction in the vertical view. .. Therefore, it is easy to take out the transport carriage downward through between the pair of rail portions.

３．上記実施形態の概要
以下、上記において説明した自動倉庫の概要について説明する。 3. 3. Outline of the above-described embodiment The outline of the automated warehouse described above will be described below.

自動倉庫は、対向して配置される一対の収納棚と、前記一対の収納棚の間に設置された複数の走行レールと、前記走行レールの上を走行する複数の搬送台車と、を備え、前記一対の収納棚の夫々は、物品を収納する棚部を上下方向に並ぶ状態で複数備え、前記走行レールは、前記棚部の夫々に対応して設置され、前記一対の収納棚の対向方向に直交する方向及び水平方向に沿う方向である搬送方向に延在し、前記複数の走行レールの夫々は、前記対向方向に間隔を空けて設置された一対のレール部を備え、前記複数の搬送台車の夫々は、前記一対のレール部を転動する走行輪を備え、
前記一対の収納棚に跨るように配置された支持部材を、更に備え、前記支持部材は、前記搬送台車を吊り下げる第１吊り下げ装置を支持する第１支持部と、前記搬送台車を吊り下げる第２吊り下げ装置を支持する第２支持部と、を備え、上下方向視で、前記第１支持部は、前記対向方向における前記一対のレール部の中央位置に重なる位置に配置され、前記第２支持部は、前記第１支持部に対して前記対向方向の一方側に配置されている。 The automated warehouse includes a pair of storage shelves arranged to face each other, a plurality of traveling rails installed between the pair of storage shelves, and a plurality of transport trolleys traveling on the traveling rails. Each of the pair of storage shelves is provided with a plurality of shelves for storing articles arranged in the vertical direction, and the traveling rail is installed corresponding to each of the shelves and faces the pair of storage shelves. Each of the plurality of traveling rails includes a pair of rail portions installed at intervals in the opposite direction, and the plurality of traveling rails extend in the transport direction which is a direction orthogonal to the direction and a direction along the horizontal direction. Each of the trolleys is provided with traveling wheels that roll on the pair of rails.
A support member arranged so as to straddle the pair of storage shelves is further provided, and the support member suspends the first support portion for supporting the first suspension device for suspending the transport carriage and the transport carriage. A second support portion for supporting the second suspension device is provided, and the first support portion is arranged at a position overlapping the central position of the pair of rail portions in the opposite direction in a vertical view. The two support portions are arranged on one side in the direction opposite to the first support portion.

この構成によれば、第１吊り下げ装置及び第２吊り下げ装置により搬送台車を搬送レールから上昇させることができ、このように搬送台車を上昇させた状態で、第１吊り下げ装置により搬送台車を支持している部分の上昇と第２吊り下げ装置により搬送台車を支持している部分の下降との一方又は双方により、搬送台車を回転させて搬送台車を横転姿勢に変更できる。そして、このように搬送台車の姿勢を変更することで、搬送台車は第１吊り下げ装置により横転姿勢で吊り下げられることになるが、第１吊り下げ装置を支持する第１支持部は、一対のレール部の中央位置に重なる位置に配置されているため、第１吊り下げ装置により吊り下げられた搬送台車は、上下方向視で、対向方向における一対のレール部の中央位置に重なる位置となる。従って、搬送台車を一対のレール部の間を通して下方に取り出すことが容易となっている。 According to this configuration, the transport carriage can be lifted from the transport rail by the first suspension device and the second suspension device, and in the state where the transport carriage is raised in this way, the transport carriage is lifted by the first suspension device. The transport carriage can be rotated and the transport carriage can be changed to the rollover posture by raising the portion supporting the transport carriage and lowering the portion supporting the transport carriage by the second suspension device. By changing the posture of the transport carriage in this way, the transport carriage is suspended in a rollover posture by the first suspension device, but the first support portions that support the first suspension device are paired. Since it is arranged at a position overlapping the center position of the rail portion of the above, the transport carriage suspended by the first suspension device is located at a position overlapping the center position of the pair of rail portions in the opposite direction in the vertical view. .. Therefore, it is easy to take out the transport carriage downward through between the pair of rail portions.

ここで、前記複数の走行レールのうち最も高い位置にある前記走行レールを、最上走行レールとして、前記第１吊り下げ装置及び前記第２吊り下げ装置の夫々は、前記搬送台車に連結する連結部と、前記連結部を前記上下方向に移動させる操作部と、を備え、前記操作部は、前記第１吊り下げ装置及び前記第２吊り下げ装置が前記支持部材に支持された状態において、前記連結部を設定高さまで上昇させることができるように構成され、前記設定高さは、前記最上走行レールの高さに、前記上下方向に隣接する前記走行レールの間隔から走行車輪の直径を引いた長さの半分の長さ以上であって、前記搬送台車の前記対向方向の長さ以下の高さを加えた高さであると好適である。 Here, the traveling rail at the highest position among the plurality of traveling rails is used as the uppermost traveling rail, and each of the first suspension device and the second suspension device is connected to the transport carriage. And an operation unit for moving the connection portion in the vertical direction, the operation unit is connected in a state where the first suspension device and the second suspension device are supported by the support member. The portion is configured to be able to be raised to a set height, and the set height is the length obtained by subtracting the diameter of the traveling wheel from the distance between the traveling rails adjacent in the vertical direction to the height of the uppermost traveling rail. It is preferable that the height is equal to or more than half the length of the rail and is equal to or less than the length of the transport carriage in the opposite direction.

この構成によれば、自動倉庫から搬出する搬送台車が複数の走行レールのいずれの上にある場合であっても、連結部を上下方向に隣接する走行レールの間隔から走行車輪の直径を引いた長さの半分の長さ以上となる設定高さまで上昇させることができるため、搬送台車を横転姿勢に変更する場合に、搬送台車が最上走行レールに接触することを回避し易い。また、設定高さは、搬送台車の前記対向方向の長さ以下の高さを加えた高さであるため、この設定高さを超えて連結部を上昇させることができる場合に比べて、支持部材の第１支持部や第２支持部の高さを比較的低く抑えることができ、支持部材の大型化を回避し易い構成となっている。 According to this configuration, the diameter of the traveling wheel is subtracted from the distance between the traveling rails adjacent to each other in the vertical direction at the connecting portion regardless of which of the plurality of traveling rails the transport carriage carried out from the automated warehouse is on. Since the height can be raised to a set height that is at least half the length, it is easy to prevent the transport carriage from coming into contact with the top traveling rail when the transport carriage is changed to the rolling posture. Further, since the set height is the height obtained by adding the height equal to or less than the length in the opposite direction of the transport carriage, it is supported as compared with the case where the connecting portion can be raised beyond this set height. The height of the first support portion and the second support portion of the member can be kept relatively low, and it is easy to avoid an increase in the size of the support member.

また、前記対向方向における、前記第１支持部に対して前記第２支持部が配置されている側を対向方向第２側とし、それとは反対側を対向方向第１側として、前記搬送台車は、前記第１吊り下げ装置により吊り下げられる第１被吊り下げ部と、前記第２吊り下げ装置により吊り下げられる第２被吊り下げ部と、を備え、前記第１被吊り下げ部は、前記第２被吊り下げ部に対して前記対向方向第１側に設けられていると好適である。 Further, in the opposite direction, the side where the second support portion is arranged with respect to the first support portion is set as the second side in the facing direction, and the opposite side is set as the first side in the facing direction. The first suspended portion is provided with a first suspended portion suspended by the first suspending device and a second suspended portion suspended by the second suspending device, and the first suspended portion is described as described above. It is preferable that the second suspended portion is provided on the first side in the opposite direction.

この構成によれば、第１吊り下げ装置により第１被支持部を吊り下げ、第２吊り下げ装置により第２被支持部を吊り下げることで、これら第１吊り下げ装置と第２吊り下げ装置とにより、対向方向において搬送台車の異なる位置を吊り下げるため、搬送台車を安定させた状態で吊り下げることができる。そして、第１吊り下げ装置により第１被吊り下げ部を上昇させることや第２吊り下げ装置により第２被吊り下げ部を下降させることで、搬送台車を搬送方向に沿う軸心周りに回転させて、搬送台車の姿勢を容易に横転姿勢とすることができる。 According to this configuration, the first suspension device and the second suspension device are suspended by suspending the first supported portion by the first suspension device and suspending the second supported portion by the second suspension device. As a result, different positions of the transport carriage are suspended in the opposite direction, so that the transport carriage can be suspended in a stable state. Then, by raising the first suspended portion by the first suspending device and lowering the second suspended portion by the second suspending device, the transport carriage is rotated around the axis along the transport direction. Therefore, the posture of the transport carriage can be easily changed to the rollover posture.

また、前記第１被吊り下げ部は、前記搬送台車の前記対向方向第１側の端部における前記搬送方向の２個所に設けられ、前記第２被吊り下げ部は、前記搬送台車の前記対向方向第２側の端部における前記搬送方向の２個所に設けられていると好適である。 Further, the first suspended portion is provided at two positions in the transport direction at the end of the transport carriage on the first side in the opposite direction, and the second suspended portion is the opposed portion of the transport carriage. It is preferable that they are provided at two positions in the transport direction at the end on the second side in the direction.

この構成によれば、第１吊り下げ装置と第２吊り下げ装置とにより、搬送台車を更に安定させた状態で吊り下げることができる。 According to this configuration, the transport carriage can be suspended in a more stable state by the first suspension device and the second suspension device.

また、前記複数の走行レールのうちの少なくとも１つにおける、前記一対のレール部の間に歩廊が備えられ、前記歩廊における前記支持部材の下方に位置する部分に、横転姿勢の前記搬送台車が前記上下方向に通過可能な開口部と、前記開口部を閉じる蓋体と、が設けられていると好適である。 Further, in at least one of the plurality of traveling rails, a corridor is provided between the pair of rail portions, and the transport carriage in a rollover posture is placed in a portion of the corridor located below the support member. It is preferable that an opening that can pass in the vertical direction and a lid that closes the opening are provided.

この構成によれば、作業者が歩廊上から収納棚や搬送台車に対するメンテナンス作業を行い得るため、収納棚や搬送台車に対するメンテナンス作業を行い易い自動倉庫となる。また、歩廊における支持部材の下方に位置する部分には、横転姿勢の搬送台車が通過可能な開口部があるため、蓋体を操作して開口部を開けることで、横転姿勢の搬送台車を歩廊の下方まで下降させることができる。 According to this configuration, since the worker can perform maintenance work on the storage shelves and the transport trolley from the corridor, the automated warehouse can easily perform the maintenance work on the storage shelves and the transport trolley. In addition, since the portion of the corridor located below the support member has an opening through which the transport trolley in the rollover posture can pass, the transport trolley in the rollover posture can be moved through the corridor by operating the lid to open the opening. Can be lowered to below.

また、横転姿勢の前記搬送台車を支持する台車搬送架台を、更に備え、前記台車搬送架台は、その前記対向方向の幅が前記一対のレール部の前記対向方向の間隔以下となっていると好適である。 Further, it is preferable that the bogie transport pedestal for supporting the transport trolley in the rollover posture is further provided, and the width of the trolley transport gantry in the facing direction is equal to or less than the distance between the pair of rail portions in the facing direction. Is.

この構成によれば、一対のレール部の間において、搬送方向に沿って台車搬送架台を移動させることができる。従って、一対のレール部の間を通して下方に取り出した搬送台車を、台車搬送架台に載せて一対の収納棚の外側まで容易に移動させることができる。 According to this configuration, the bogie transport pedestal can be moved along the transport direction between the pair of rail portions. Therefore, the transport trolley taken out downward through between the pair of rail portions can be placed on the trolley transport pedestal and easily moved to the outside of the pair of storage shelves.

また、前記搬送方向の一方側を搬送方向第１側とし、その反対側を搬送方向第２側として、前記一対の収納棚に対して前記搬送方向第１側にのみ、前記自動倉庫に入庫する物品又は前記自動倉庫から出庫する物品を前記上下方向に移動させる昇降装置を備え、前記支持部材は、前記一対の収納棚における前記搬送方向の中央位置よりも前記搬送方向第２側に配置されていると好適である。 Further, one side in the transport direction is set as the first side in the transport direction, and the opposite side is set as the second side in the transport direction. An elevating device for moving an article or an article to be delivered from the automatic warehouse in the vertical direction is provided, and the support member is arranged on the second side of the pair of storage shelves in the transport direction with respect to the central position in the transport direction. It is preferable to have it.

この構成では、横転姿勢の搬送台車を自動倉庫から取り出す場合は、障害物となる昇降装置が備えられていない搬送方向第２側からの方が取り出し易い。そして、この構成によれば、支持部材は、一対の収納棚における搬送方向の中央位置よりも前記搬送方向第２側に配置されているため、支持部材により横転姿勢にされた搬送台車を自動倉庫の搬送方向第２側から取り出すときの移動距離を比較的短くすることができる。よって、横転姿勢の搬送台車を自動倉庫から容易に取り出すことができる。 In this configuration, when the transport trolley in the rollover posture is taken out from the automated warehouse, it is easier to take out from the second side in the transport direction, which is not provided with the lifting device that becomes an obstacle. According to this configuration, since the support member is arranged on the second side in the transport direction with respect to the central position in the transport direction in the pair of storage shelves, the transport trolley in the rollover posture by the support member is automatically stored. The moving distance when taking out from the second side in the transport direction can be relatively short. Therefore, the transport trolley in the rollover posture can be easily taken out from the automated warehouse.

本開示に係る技術は、一対の収納棚と、一対の収納棚の間に設置された走行レールの上を走行する搬送台車と、を備えた自動倉庫に利用することができる。 The technique according to the present disclosure can be used in an automated warehouse provided with a pair of storage shelves and a transport trolley running on a traveling rail installed between the pair of storage shelves.
