搬送装置(TRANSPORT APPARATUS)TRANSPORT APPARATUS
 本発明は、容器を搬送する搬送装置に関する。 The present invention relates to a transport device for transporting containers.

 特許文献1に開示された移載装置(2)は、荷物(10)を載置する荷載置部(26)と、荷物(10)の移載方向に往復移動するトップ部(42)を有したスライドアーム(28)と、を備えている。移載装置(2)は、スライドアーム(28)におけるトップ部(42)の往復移動を利用して、荷載置部(26)からラック(12a,12b)へ荷物(10)を移載する卸し動作と、ラック(12a,12b)から荷載置部(26)へ荷物(10)を移載する掬い動作と、を行うように構成されている。また、当該移載装置(2)においては、荷物(10)の取っ手(14a,14b)にフック(30,32,34,36)を係合させた状態で、卸し動作及び掬い動作を行う。なお、上記において括弧内に示された符号は、特許文献1のものである。 The transfer device (2) disclosed in Patent Document 1 includes a loading section (26) on which the luggage (10) is placed, and a slide arm (28) having a top section (42) that moves back and forth in the direction of transferring the luggage (10). The transfer device (2) is configured to perform a lowering operation of transferring the luggage (10) from the loading section (26) to the racks (12a, 12b) and a scooping operation of transferring the luggage (10) from the racks (12a, 12b) to the loading section (26) by utilizing the reciprocating movement of the top section (42) of the slide arm (28).

特許第6337706号公報Patent No. 6337706
 ところで、移載対象が容器などである場合、例えば、物品が容器内に偏って配置されることで、当該容器に収容された物品の重心位置に移載方向の偏りが生じる場合がある。このような場合、卸し動作中及び掬い動作中に容器に移載方向の傾きが生じる可能性がある。そして、容器に移載方向の傾きが生じると、移載動作中にフックなどの係止具が容器から脱離するなどの事態が発生し、移載動作に支障を来す可能性がある。 Incidentally, when the object to be transferred is a container or the like, for example, the items may be unevenly placed inside the container, causing the transfer direction to be biased with respect to the center of gravity of the items contained in the container. In such cases, the container may tilt in the transfer direction during the unloading and scooping operations. If the container tilts in the transfer direction, it may cause an incident such as a hook or other fastening device coming off the container during the transfer operation, causing an interruption to the transfer operation.
 本発明は、以上の実情に鑑みなされたものであり、物品の移載動作中における容器の姿勢を正しく維持し易い搬送装置の実現を、その目的とする。 The present invention was developed in consideration of the above situation, and aims to realize a conveying device that can easily maintain the correct orientation of containers during the transfer of items.
 容器を搬送する搬送装置であって、
 前記容器を保持する保持部を有する移載装置を備え、
 前記移載装置は、水平方向に沿う移載方向に沿って前記容器を移動させて、前記保持部から移載対象箇所へ前記容器を移載する卸し動作、及び前記移載対象箇所から前記保持部へ前記容器を移載する掬い動作を含む移載動作を行うように構成され、
 前記移載方向における前記保持部から前記移載対象箇所へ向かう側を移載方向卸し側、前記移載方向における前記移載対象箇所から前記保持部へ向かう側を移載方向掬い側とし、上下方向視で前記移載方向に直交する方向を幅方向とし、前記容器における前記移載方向卸し側を向く部分を容器前面部、前記容器における前記移載方向掬い側を向く部分を容器後面部として、
 前記移載装置は、前記卸し動作において前記容器を押圧する押圧部と、前記掬い動作において前記容器に係止される係止部と、前記押圧部及び前記係止部に対して前記幅方向の少なくとも一方側に配置されて前記卸し動作及び前記掬い動作における前記容器の上下動を規制する規制部と、前記押圧部、前記係止部、及び前記規制部を前記移載方向に沿って往復移動させる移載駆動部と、を備え、
 前記容器後面部に、下側に向かって開口する凹部と、前記移載方向掬い側に突出すると共に前記容器後面部に沿って水平方向に延在するように形成されたリブ部と、が設けられ、
 前記移載装置は、前記押圧部を、前記容器後面部に当接させた状態で前記移載駆動部により前記移載方向卸し側へ移動させることで、前記卸し動作を行い、前記係止部を、前記凹部に対して下側から挿入した状態で前記移載駆動部により前記移載方向掬い側へ移動させることで、前記掬い動作を行い、
 前記規制部は、前記卸し動作中及び前記掬い動作中に前記リブ部に対して上側であって上下方向視で前記リブ部と重複する位置に配置される上側押さえ部を備える。
A conveying device for conveying a container,
A transfer device having a holding part for holding the container,
The transfer device is configured to move the container along a horizontal transfer direction to perform a transfer operation including a lowering operation for transferring the container from the holding unit to a transfer target location, and a scooping operation for transferring the container from the transfer target location to the holding unit,
The side from the holding unit to the target location in the transfer direction is the unloading side in the transfer direction, the side from the target location to the holding unit in the transfer direction is the scooping side in the transfer direction, the direction perpendicular to the transfer direction when viewed in the up-down direction is the width direction, the part of the container facing the unloading side in the transfer direction is the container front part, and the part of the container facing the scooping side in the transfer direction is the container rear part,
The transfer device includes a pressing unit that presses the container during the unloading operation, a locking unit that locks onto the container during the scooping operation, a regulating unit that is disposed on at least one side of the pressing unit and the locking unit in the width direction and that regulates the up and down movement of the container during the unloading operation and the scooping operation, and a transfer drive unit that reciprocates the pressing unit, the locking unit, and the regulating unit along the transfer direction,
The rear surface of the container is provided with a recess that opens downward and a rib portion that protrudes toward the scooping side in the transfer direction and extends horizontally along the rear surface of the container,
The transfer device performs the unloading operation by moving the pressing part toward the unloading side in the transfer direction by the transfer drive part while the pressing part is in contact with the rear surface part of the container, and performs the scooping operation by moving the locking part toward the scooping side in the transfer direction by the transfer drive part while the locking part is inserted into the recess from below,
The regulating portion includes an upper pressing portion that is arranged above the rib portion and at a position overlapping with the rib portion when viewed in the up-down direction during the unloading operation and the scooping operation.
 本構成によれば、卸し動作中及び掬い動作中に容器後面部の側が容器前面部の側よりも上側に持ち上がりそうになった場合には、上昇しようとするリブ部の移動が上側押さえ部により規制される。従って、卸し動作中及び掬い動作中における容器の姿勢を正しく維持し易い。そのため、例えば容器に収容された物品の重心位置に移載方向の偏りがある場合でも、容器後面部が持ち上がった状態になり難くすることができる。
 つまり、本構成によれば、物品の移載動作中における容器の姿勢を正しく維持し易い搬送装置を実現できる。
According to this configuration, if the rear side of the container is about to rise higher than the front side of the container during the unloading and scooping operations, the movement of the rib that is about to rise is restricted by the upper pressing part. Therefore, it is easy to maintain the correct posture of the container during the unloading and scooping operations. Therefore, for example, even if the center of gravity of the item contained in the container is biased in the transfer direction, it is possible to prevent the rear side of the container from being raised.
In other words, according to this configuration, a conveying device can be realized that can easily maintain the correct orientation of the container during the article transfer operation.

 搬送装置は、容器を搬送する装置である。以下、搬送装置が、容器を搬送する搬送設備に備えられている場合を例示して、当該搬送装置の実施形態について説明する。 The transport device is a device that transports containers. Below, an embodiment of the transport device will be described, taking as an example a case where the transport device is provided in a transport facility that transports containers.
 図1に示すように、搬送設備Fは、容器70(図3及び図4参照)を収納する容器棚8と、容器70の搬出及び搬入を行う搬出入部9と、を備えている。搬送装置100は、搬出入部9によって搬入された容器70を容器棚8へ搬送し、又は、容器棚8に収納された容器70を搬出のために搬出入部9へ搬送する。 As shown in FIG. 1, the transport equipment F includes a container shelf 8 that stores containers 70 (see FIG. 3 and FIG. 4), and an loading/unloading section 9 that loads and unloads the containers 70. The transport device 100 transports the containers 70 loaded by the loading/unloading section 9 to the container shelf 8, or transports the containers 70 stored on the container shelf 8 to the loading/unloading section 9 for unloading.
 本実施形態では、複数の容器棚8が、規定の間隔を空けつつ互いに平行に配置されている。複数の容器棚8のそれぞれは少なくとも正面が開口しており、当該正面において容器70の出し入れが行われる。そして、正面が向かい合って隣り合う一対の容器棚8の間に、搬送装置100の走行経路Rの一部が設定されている。また、搬送設備Fに備えられた複数の容器棚8のうち最も端に配置された容器棚8は、正面を外側に向けて配置されており、当該端の容器棚8の正面に沿った領域にも走行経路Rの一部が設定されている。また、搬送設備Fには、複数の搬出入部9が設けられており、複数の搬出入部9のそれぞれを通る領域にも、走行経路Rの一部が設定されている。 In this embodiment, multiple container shelves 8 are arranged parallel to each other with a specified distance between them. Each of the multiple container shelves 8 is open at least at the front, and containers 70 are loaded and unloaded from this front. A portion of the travel path R of the conveying device 100 is set between a pair of adjacent container shelves 8 whose front faces each other. In addition, the container shelf 8 located at the very end of the multiple container shelves 8 provided in the conveying equipment F is arranged with its front facing outward, and a portion of the travel path R is also set in the area along the front of the end container shelf 8. In addition, the conveying equipment F is provided with multiple loading and unloading sections 9, and a portion of the travel path R is also set in the area that passes through each of the multiple loading and unloading sections 9.
 走行経路Rは、容器棚8の正面に沿って当該容器棚8の延在方向に延びる棚内経路Raと、容器棚8の配置領域の外部において棚内経路Raに交差する棚外経路Rbと、を含んでいる。棚内経路Raは、複数の容器棚8のそれぞれに対応して設定されている。本実施形態では、正面が向かい合って隣り合う一対の容器棚8の間の領域に設定された走行経路Rの一部、及び、正面を外側に向けて配置された容器棚8の当該正面に沿った領域に設定された走行経路Rの一部が、棚内経路Raに相当する。また、棚外経路Rbは、複数の棚内経路Raを繋ぐように設定されている。また、棚外経路Rbは、複数の搬出入部9のそれぞれを通るようにも設定されている。本実施形態では、走行経路Rにおける棚内経路Ra以外の部分が、棚外経路Rbに相当する。 The travel path R includes an intra-shelf path Ra that extends along the front of the container shelf 8 in the extension direction of the container shelf 8, and an extra-shelf path Rb that intersects with the intra-shelf path Ra outside the arrangement area of the container shelf 8. The intra-shelf path Ra is set corresponding to each of the multiple container shelves 8. In this embodiment, a part of the travel path R set in the area between a pair of adjacent container shelves 8 whose front faces each other, and a part of the travel path R set in the area along the front of the container shelf 8 arranged with its front facing outward, correspond to the intra-shelf path Ra. The extra-shelf path Rb is set to connect the multiple intra-shelf paths Ra. The extra-shelf path Rb is also set to pass through each of the multiple loading/unloading sections 9. In this embodiment, the part of the travel path R other than the intra-shelf path Ra corresponds to the extra-shelf path Rb.
〔容器棚〕
 図2に示すように、容器棚8は、容器70を収納する棚部80を上下方向に複数段備えている。棚部80は、後述する移載装置4によって容器70を移載する場合の移載対象箇所Tとされる。本実施形態では、容器棚8は、複数の支柱部材81と複数の梁部材82とを組み合わせて構成されている。複数の梁部材82が、上下方向に間隔を空けて配置されている。そして、複数の梁部材82のそれぞれに、容器70を載置するための載置部材83が連結されている。本例では、容器70は、一対の載置部材83に載置されることにより、棚部80に収納される。また、棚部80には、一対の載置部材83の組が複数組配置されており、1つの棚部80において複数の容器70を収納可能となっている。なお、本例では、図2に示す正面視で左右方向に隣接する一対の支柱部材81の間であって、上下方向に隣接する一対の梁部材82の間の領域が、容器棚8の開口に相当する。
[Container shelf]
As shown in FIG. 2, the container shelf 8 has a plurality of shelves 80 for storing the containers 70 in the vertical direction. The shelves 80 are the transfer target locations T when the containers 70 are transferred by the transfer device 4 described later. In this embodiment, the container shelf 8 is configured by combining a plurality of support members 81 and a plurality of beam members 82. The plurality of beam members 82 are arranged at intervals in the vertical direction. A mounting member 83 for placing the containers 70 is connected to each of the plurality of beam members 82. In this example, the containers 70 are stored in the shelf section 80 by being placed on a pair of mounting members 83. In addition, a plurality of pairs of mounting members 83 are arranged in the shelf section 80, and a plurality of containers 70 can be stored in one shelf section 80. Note that in this example, the area between a pair of support members 81 adjacent to each other in the left-right direction and between a pair of beam members 82 adjacent to each other in the vertical direction in the front view shown in FIG. 2 corresponds to the opening of the container shelf 8.
 本実施形態では、棚部80における容器70を収納するための基準位置80Pに、当該基準位置80Pにおいて容器70を収納するための目標となる目標部82Tが設けられている。本例では、目標部82Tは、梁部材82に設けられている。目標部82Tは、一対の載置部材83の組につき1つ設けられている。図示の例では、目標部82Tは、梁部材82に形成された孔によって構成されている。 In this embodiment, a target portion 82T that serves as a target for storing the container 70 at a reference position 80P for storing the container 70 on the shelf portion 80 is provided. In this example, the target portion 82T is provided on the beam member 82. One target portion 82T is provided for each pair of mounting members 83. In the illustrated example, the target portion 82T is constituted by a hole formed in the beam member 82.
〔容器〕
 図3に示すように、容器70は、上方に開口する開口部71と、容器70の内部空間を囲む周壁部72と、を備えた箱状に形成されている。本例では、上下方向視における容器70の外形は、矩形状を成している。周壁部72によって囲まれた内部空間、すなわち容器70の内部には、物品が収容可能となっている。物品には、例えば、食料品や生活用品などの各種商品、又は、工場の生産ライン等において用いられる部品や仕掛品などが含まれる。
〔container〕
3, the container 70 is formed in a box shape with an opening 71 that opens upward and a peripheral wall portion 72 that surrounds the internal space of the container 70. In this example, the external shape of the container 70 when viewed in the vertical direction is rectangular. The internal space surrounded by the peripheral wall portion 72, i.e., the inside of the container 70, can accommodate items. Examples of items include various products such as food and daily necessities, or parts and work in progress used in a production line in a factory.
 本実施形態では、容器70は、その内部に物品を収容した状態で、別の容器70と積み重ねることが可能に構成されている。すなわち、容器70は、上下方向に段積み可能に構成されている(図5も参照)。本例では、容器70は、その底部から下方に突出する嵌合部77を備えている。容器70の嵌合部77が、別の容器70の開口部71に対して上方から嵌合することにより、2つの容器70が上下方向に段積みされる。 In this embodiment, the container 70 is configured so that it can be stacked on top of another container 70 while holding items inside. That is, the container 70 is configured so that it can be stacked vertically (see also FIG. 5). In this example, the container 70 has a fitting portion 77 that protrudes downward from its bottom. The fitting portion 77 of the container 70 fits into the opening 71 of the other container 70 from above, thereby stacking the two containers 70 vertically.
 容器70は、後述する移載装置4によって、特定の方向に沿って移載されるように構成されている。移載装置4によって容器70を移載する方向を移載方向Xとすると(図4参照)、容器70は、移載装置4によって移載方向Xに沿って移動される。より詳細には、移載装置4が、移載対象箇所Tに対して容器70を卸す場合には、容器70は、移載方向Xにおける一方側(以下、「移載方向卸し側X1」と称する。)に向かって移動する。移載装置4が、移載対象箇所Tに対して容器70を掬う場合には、容器70は、移載方向Xにおける他方側(以下、「移載方向掬い側X2」と称する。)に向かって移動する。 The container 70 is configured to be transferred along a specific direction by the transfer device 4, which will be described later. If the direction in which the container 70 is transferred by the transfer device 4 is the transfer direction X (see FIG. 4), the container 70 is moved along the transfer direction X by the transfer device 4. More specifically, when the transfer device 4 unloads the container 70 onto the target transfer location T, the container 70 moves toward one side in the transfer direction X (hereinafter referred to as the "unloading side X1 in the transfer direction"). When the transfer device 4 scoops up the container 70 from the target transfer location T, the container 70 moves toward the other side in the transfer direction X (hereinafter referred to as the "scooping side X2 in the transfer direction").
 容器70における移載方向卸し側X1を向く部分を容器前面部70F、容器70における移載方向掬い側X2を向く部分を容器後面部70Rとする(図4参照)。図2に示すように、容器70は、容器後面部70Rを容器棚8の正面側に向けた状態で、棚部80に収納される。 The portion of the container 70 facing the unloading side X1 in the transfer direction is the container front portion 70F, and the portion of the container 70 facing the scooping side X2 in the transfer direction is the container rear portion 70R (see Figure 4). As shown in Figure 2, the container 70 is stored on the shelf portion 80 with the container rear portion 70R facing the front side of the container shelf 8.
 図3及び図4に示すように、本実施形態では、容器70は、周壁部72から外側に突出する複数のリブ部を備えている。複数のリブ部のうち一部は、後述する持ち上げ装置3によって持ち上げられる持ち上げ用リブ部73である。本例では、持ち上げ用リブ部73は、周壁部72の上部に形成されている。また、持ち上げ用リブ部73は、周壁部72における開口部71を囲む部分の全周に亘って形成されている。複数のリブ部のうち一部は、後述する移載装置4による移載動作の際に持ち上げられる移載用リブ部74である。本例では、移載用リブ部74は、持ち上げ用リブ部73よりも下方に形成されている。移載用リブ部74は、容器後面部70Rに設けられている。本例では、移載用リブ部74は、容器後面部70R及び容器前面部70Fの双方に設けられている。なお、本実施形態では、容器後面部70Rと容器前面部70Fとは同じ構成となっている。すなわち、移載用リブ部74は、移載方向掬い側X2に突出すると共に容器後面部70Rに沿って水平方向に延在するように形成されている。本実施形態では、移載用リブ部74が「リブ部」に相当する。 3 and 4, in this embodiment, the container 70 has a plurality of rib portions protruding outward from the peripheral wall portion 72. Some of the plurality of rib portions are lifting rib portions 73 that are lifted by the lifting device 3 described later. In this example, the lifting rib portion 73 is formed on the upper part of the peripheral wall portion 72. The lifting rib portion 73 is formed around the entire circumference of the portion surrounding the opening 71 in the peripheral wall portion 72. Some of the plurality of rib portions are transfer rib portions 74 that are lifted during a transfer operation by the transfer device 4 described later. In this example, the transfer rib portion 74 is formed below the lifting rib portion 73. The transfer rib portion 74 is provided on the container rear surface portion 70R. In this example, the transfer rib portion 74 is provided on both the container rear surface portion 70R and the container front surface portion 70F. In this embodiment, the container rear surface portion 70R and the container front surface portion 70F have the same configuration. That is, the transfer rib portion 74 is formed so as to protrude toward the scooping side X2 in the transfer direction and extend horizontally along the container rear surface portion 70R. In this embodiment, the transfer rib portion 74 corresponds to the "rib portion."
 容器後面部70Rには、下側に向かって開口する凹部75が設けられている。本実施形態では、凹部75は、鉛直下方に開口している。凹部75は、容器70における移載用リブ部74が設けられた面(本例では、容器後面部70R及び容器前面部70F)に形成されている。本例では、容器70は、持ち上げ用リブ部73と移載用リブ部74との上下方向の間に、周壁部72から外側に突出すると共に下方に延在する係止用壁部76を備えており、この係止用壁部76と周壁部72との間に凹部75が形成されている。係止用壁部76は、後述するように、移載装置4による移載動作の際に、係止部Bb(図9参照)が係止される部分である。 The rear surface 70R of the container is provided with a recess 75 that opens downward. In this embodiment, the recess 75 opens vertically downward. The recess 75 is formed on the surface of the container 70 on which the transfer rib 74 is provided (in this example, the rear surface 70R of the container and the front surface 70F of the container). In this example, the container 70 is provided with a locking wall 76 that protrudes outward from the peripheral wall 72 and extends downward between the lifting rib 73 and the transfer rib 74 in the vertical direction, and the recess 75 is formed between the locking wall 76 and the peripheral wall 72. The locking wall 76 is the portion that locks the locking part Bb (see FIG. 9) during the transfer operation by the transfer device 4, as described later.
 上下方向に沿う上下方向視で移載方向Xに直交する方向を幅方向Yとすると、本実施形態では、凹部75は、容器後面部70R及び容器前面部70Fのそれぞれにおける幅方向Yの中央部に設けられている。そして、本例では、凹部75は、幅方向Y及び上下方向に沿って延びるように形成されている。 If the direction perpendicular to the transfer direction X when viewed from the top-bottom direction is defined as the width direction Y, in this embodiment, the recess 75 is provided in the center of the width direction Y on each of the container rear surface portion 70R and the container front surface portion 70F. In this example, the recess 75 is formed to extend along the width direction Y and the top-bottom direction.

[Transportation device]
As shown in FIG. 5, the conveying device 100 includes a traveling vehicle 1, a container group support section 2 that supports a plurality of containers 70 as a stacked container group 7 in a specified stacking area 2A, a lifting device 3 that lifts the containers 70 of the container group 7 supported by the container group support section 2, and a transfer device 4 that transfers the containers 70. The container group support section 2, the lifting device 3, and the transfer device 4 are mounted on the traveling vehicle 1. If the direction along the traveling direction of the traveling vehicle 1 is defined as the "vehicle body longitudinal direction L", the container group support section 2 and the transfer device 4 are arranged side by side in the vehicle body longitudinal direction L on the traveling vehicle 1. In the following, the direction perpendicular to the vehicle body longitudinal direction L when viewed in the up-down direction is defined as the "vehicle body width direction W". Here, the vehicle body longitudinal direction L and the vehicle body width direction W are horizontal directions perpendicular to each other.
 本実施形態では、搬送装置100は、制御装置Cを備えている。制御装置Cは、搬送装置100の各機能部を制御する。本例では、制御装置Cは、走行体1、容器群支持部2、持ち上げ装置3、移載装置4、及び、後述する旋回装置5を制御する。容器70を搬送及び移載するための動作は、制御装置Cによる各機能部の制御によって実現される。制御装置Cは、例えば、マイクロコンピュータ等のプロセッサ、メモリ等の周辺回路等を備えている。そして、これらのハードウェアとコンピュータ等のプロセッサ上で実行されるプログラムとの協働により、各機能が実現される。 In this embodiment, the conveying device 100 is equipped with a control device C. The control device C controls each functional part of the conveying device 100. In this example, the control device C controls the running body 1, the container group support part 2, the lifting device 3, the transfer device 4, and the rotating device 5 described below. The operation for conveying and transferring the container 70 is realized by the control of each functional part by the control device C. The control device C is equipped with, for example, a processor such as a microcomputer, peripheral circuits such as a memory, etc. Then, each function is realized by cooperation between this hardware and a program executed on a processor of a computer or the like.
〔走行体〕
 走行体1は、規定の走行経路R(図1参照)を走行するように構成されている。本実施形態では、走行体1は、棚内経路Raと棚外経路Rbとを走行するように構成されている。走行体1は、棚内経路Raを走行する場合に、容器棚8に沿って走行するように構成され、より詳細には、容器棚8の正面に沿って走行するように構成されている。本実施形態では、走行体1は、床面を走行するように構成されている。
[Running body]
The running body 1 is configured to run on a specified running path R (see FIG. 1 ). In this embodiment, the running body 1 is configured to run on an intra-shelf path Ra and an extra-shelf path Rb. When running on the intra-shelf path Ra, the running body 1 is configured to run along the container shelf 8, and more specifically, configured to run along the front surface of the container shelf 8. In this embodiment, the running body 1 is configured to run on the floor surface.
 走行体1は、複数の走行車輪10と、複数の走行車輪10のうち少なくとも1つを駆動する走行駆動部10Mと、を備えている。走行駆動部10Mは、不図示のモータを含んで構成されている。走行駆動部10Mが走行車輪10を駆動することにより、走行体1に走行方向の推進力が付与される。 The running body 1 is equipped with a number of running wheels 10 and a running drive unit 10M that drives at least one of the multiple running wheels 10. The running drive unit 10M is configured to include a motor (not shown). The running drive unit 10M drives the running wheels 10, thereby imparting a propulsive force in the running direction to the running body 1.
〔容器群支持部〕
 容器群支持部2は、走行体1に搭載されている。容器群支持部2は、複数の容器70を段積み状態の容器群7として支持可能に構成されている。容器群支持部2の上方には、容器群7が配置される段積み領域2Aが規定されている。段積み領域2Aは、容器群支持部2から上方に延在する立体的な仮想領域である。本例では、容器群支持部2は、容器群7を載置した状態で当該容器群7を移動させることが可能なコンベヤとして構成されている。本例では、容器群支持部2は、容器群7を車体幅方向Wに沿って移動させることが可能となっている。容器群支持部2を構成するコンベヤとしては、ローラコンベヤ、チェーンコンベヤ、ベルトコンベヤなどの周知のコンベヤ等であって良い。
[Container group support section]
The container group support section 2 is mounted on the traveling body 1. The container group support section 2 is configured to be able to support a plurality of containers 70 as a container group 7 in a stacked state. A stacking area 2A in which the container group 7 is arranged is defined above the container group support section 2. The stacking area 2A is a three-dimensional virtual area extending upward from the container group support section 2. In this example, the container group support section 2 is configured as a conveyor capable of moving the container group 7 in a state in which the container group 7 is placed. In this example, the container group support section 2 is capable of moving the container group 7 along the vehicle body width direction W. The conveyor constituting the container group support section 2 may be a well-known conveyor such as a roller conveyor, a chain conveyor, or a belt conveyor.
 搬出入部9(図1参照)には、複数の容器70が段積みされた状態の容器群7が搬入される。走行体1が搬出入部9に隣接した状態で、容器群支持部2は、搬出入部9から容器群7を受け取り、または、搬出入部9へ容器群7を引き渡す。すなわち、容器群支持部2は、搬出入部9との間で容器群7の受け渡しを行うように構成されている。詳細な図示は省略するが、本例では、搬出入部9は、容器70から物品を取り出す作業が行われるピッキングエリアに隣接している。容器群支持部2から搬出入部9へ容器群7が引き渡されると、搬出入部9に隣接するピッキングエリアにおいて容器70から物品が取り出される。容器70に収容された物品の一部又は全部が取り出された後は、当該容器70は、搬出入部9から容器群支持部2(搬送装置100)に引き渡されて、再び容器棚8へ搬送される。但し、搬出入部9は、ピッキングエリアに隣接していなくても良く、他の設備や作業エリアに隣接していても良い。また、例えば、搬出入部9は、容器群支持部2から引き渡された容器群7を搬送設備Fの外部へ搬送するように構成されていても良い。 A container group 7 in which multiple containers 70 are stacked is carried into the loading/unloading section 9 (see FIG. 1). With the traveling body 1 adjacent to the loading/unloading section 9, the container group support section 2 receives the container group 7 from the loading/unloading section 9 or transfers the container group 7 to the loading/unloading section 9. In other words, the container group support section 2 is configured to transfer the container group 7 between the loading/unloading section 9. Although detailed illustration is omitted, in this example, the loading/unloading section 9 is adjacent to a picking area where the work of removing items from the containers 70 is performed. When the container group 7 is transferred from the container group support section 2 to the loading/unloading section 9, the items are removed from the containers 70 in the picking area adjacent to the loading/unloading section 9. After some or all of the items contained in the containers 70 have been removed, the containers 70 are transferred from the loading/unloading section 9 to the container group support section 2 (transport device 100) and transported again to the container shelf 8. However, the loading/unloading section 9 does not have to be adjacent to the picking area, and may be adjacent to other equipment or work areas. Also, for example, the loading/unloading section 9 may be configured to transport the container group 7 delivered from the container group support section 2 to the outside of the transport equipment F.
〔持ち上げ装置〕
 持ち上げ装置3は、走行体1に搭載されている。持ち上げ装置3は、容器群支持部2に支持された容器群7の容器70、換言すれば、段積み領域2Aに配置された容器群7の容器70を持ち上げるように構成されている。
[Lifting device]
The lifting device 3 is mounted on the traveling body 1. The lifting device 3 is configured to lift the containers 70 of the container group 7 supported by the container group support portion 2, in other words, the containers 70 of the container group 7 arranged in the stacking area 2A.
 持ち上げ装置3は、走行体1から上方に立設された持ち上げ用マスト30と、持ち上げ用マスト30に連結された持ち上げ用昇降体30Bと、持ち上げ用昇降体30Bを持ち上げ用マスト30に沿って昇降させる持ち上げ用昇降体駆動部30Mと、を備えている。詳細な図示は省略するが、持ち上げ用昇降体駆動部30Mは、例えば、持ち上げ用昇降体30Bに連結されたベルト等の無端体と、当該無端体が巻回された回転体と、当該回転体を回転駆動するモータと、を備えている。 The lifting device 3 comprises a lifting mast 30 erected upward from the running body 1, a lifting body 30B connected to the lifting mast 30, and a lifting body drive unit 30M that raises and lowers the lifting body 30B along the lifting mast 30. Although detailed illustration is omitted, the lifting body drive unit 30M comprises, for example, an endless body such as a belt connected to the lifting body 30B, a rotating body around which the endless body is wound, and a motor that rotates and drives the rotating body.
 持ち上げ装置3は、段積み領域2Aに段積みされた容器群7の内の任意の高さの容器70を、当該容器70の持ち上げ用リブ部73を下方から保持した状態で、当該容器70の下に隣接する容器70に対して持ち上げる第1持ち上げ機構31と、第1持ち上げ機構31により持ち上げられた容器70よりも下方の容器70を、当該容器70の持ち上げ用リブ部73を下方から保持した状態で、当該容器70の下に隣接する容器70に対して持ち上げる第2持ち上げ機構32と、を備えている。また、本実施形態では、第1持ち上げ機構31と第2持ち上げ機構32とが、上下方向に離間して配置されている。これにより、図示については省略するが、第1持ち上げ機構31によって持ち上げられた容器70と、第2持ち上げ機構32によって持ち上げられた容器70との、上下方向の間にスペースを形成することが可能になっている。また、第2持ち上げ機構32によって持ち上げられた容器70の下方にも、上下方向のスペースを形成することが可能となっている。 The lifting device 3 includes a first lifting mechanism 31 that lifts a container 70 of any height among the containers 7 stacked in the stacking area 2A, while holding the lifting rib portion 73 of the container 70 from below, against the adjacent container 70 below the container 70, and a second lifting mechanism 32 that lifts a container 70 below the container 70 lifted by the first lifting mechanism 31, against the adjacent container 70 below the container 70, while holding the lifting rib portion 73 of the container 70 from below. In this embodiment, the first lifting mechanism 31 and the second lifting mechanism 32 are arranged spaced apart in the vertical direction.

[Transfer device]
As shown in FIG. 5, the transfer device 4 is mounted on the traveling body 1. The transfer device 4 has a holding part A that holds the container 70, and is configured to move the container 70 along a horizontal transfer direction X to perform a transfer operation including an unloading operation of transferring the container 70 from the holding part A to a transfer target location T, and a scooping operation of transferring the container 70 from the transfer target location T to the holding part A. In this specification, the transfer of the container 70 from the transfer target location T to the transfer device 4 is referred to as "scooping", and "scooping" is not limited to a specific transfer operation. In this embodiment, the transfer device 4 is equipped with a transfer machine B, and the transfer machine B performs the unloading operation and the scooping operation of the container 70 at the transfer target location T. The transfer target location T includes the stacking area 2A and the shelf part 80 of the container shelf 8.
 上述のように、ここでは、移載装置4により移載される容器70の移動方向を移載方向Xとする。また、移載方向Xにおける保持部Aから移載対象箇所Tへ向かう側を移載方向卸し側X1、移載方向Xにおける移載対象箇所Tから保持部Aへ向かう側を移載方向掬い側X2とする。移載方向Xは、水平方向に沿う方向である。移載方向卸し側X1は、容器70を卸す場合に、移載方向Xに沿って容器70が移動する側である。移載方向掬い側X2は、容器70を掬う場合に、移載方向Xに沿って容器70が移動する側である。 As described above, here, the movement direction of the container 70 transferred by the transfer device 4 is referred to as the transfer direction X. Furthermore, the side in the transfer direction X from the holding section A to the target transfer location T is referred to as the transfer direction unloading side X1, and the side in the transfer direction X from the target transfer location T to the holding section A is referred to as the transfer direction scooping side X2. The transfer direction X is a direction along the horizontal direction. The transfer direction unloading side X1 is the side along which the container 70 moves in the transfer direction X when the container 70 is unloaded. The transfer direction scooping side X2 is the side along which the container 70 moves in the transfer direction X when the container 70 is scooped.

As shown in FIG. 6, the turning device 5 is configured to turn the transfer device 4 around an axis along the vertical direction to change the orientation of the transfer device 4 between a first position P1 in which the transfer direction X faces the stacking area 2A, and a second position P2 in which the transfer direction X faces the container shelf 8. In this way, in this embodiment, the transfer direction X can be changed within the horizontal plane by the turning device 5.
 本実施形態では、移載装置4は、移載対象箇所Tの位置に応じて姿勢を変更する。具体的には、移載装置4は、移載対象箇所Tが段積み領域2Aである場合に第1姿勢P1となり、移載対象箇所Tが棚部80(容器棚8)である場合に第2姿勢P2となる。図7に示すように、本例では、旋回装置5は、移載装置4を支持する旋回台50と、後述する移載用昇降体40Bに対して旋回台50を旋回自在に支持する旋回軸51と、旋回軸51を駆動する旋回駆動部5Mと、を備えている。なお、図7は、移載装置4が第2姿勢P2である場合を示している。 In this embodiment, the transfer device 4 changes its posture depending on the position of the transfer target location T. Specifically, the transfer device 4 takes a first posture P1 when the transfer target location T is the stacking area 2A, and takes a second posture P2 when the transfer target location T is the shelf section 80 (container shelf 8).

In this embodiment, the pressing part Ba is supported by the support member Bs by being connected to a pressing connection part Bac formed to rise upward from the upper surface of the support member Bs. The pressing part Ba is located on the unloading side X1 in the transfer direction relative to the pressing connection part Bac. In this embodiment, the pressing part Ba has an abutment surface Baf that abuts against the container rear surface part 70R during the unloading operation. The abutment surface Baf is configured to abut against the locking wall part 76 of the container 70 from the scooping side X2 in the transfer direction during the unloading operation (see FIG. 14).
 係止部Bbは、掬い動作において、容器70に係止され、当該容器70を移載方向掬い側X2に向けて引き込む。係止部Bbは、係止駆動部Mbにより回転駆動されることで、容器70の凹部75に挿入される係止姿勢(図11参照)と、凹部75から出る非係止姿勢(図10参照)と、に姿勢変更可能に構成されている。 The locking portion Bb is locked to the container 70 during the scooping operation, and pulls the container 70 toward the scooping side X2 in the transfer direction. The locking portion Bb is rotationally driven by the locking drive portion Mb, and is configured to be able to change its position between a locked position in which it is inserted into the recess 75 of the container 70 (see FIG. 11) and a non-locked position in which it comes out of the recess 75 (see FIG. 10).
 本実施形態では、係止部Bbは、支持部材Bsにおける本体部Bspに対して下方に配置された回転軸Bxに連結されている。回転軸Bxは、移載方向Xに沿って配置されており、係止駆動部Mbによって移載方向Xに沿う軸心まわりに回転駆動される。係止駆動部Mbは、支持部材Bsにおける本体部Bspに対して下方に配置されていると共に、支持部材Bsに対して固定されている。このように、係止部Bbは、回転軸Bx及び係止駆動部Mbを介して支持部材Bsに支持されている。そして、係止部Bbは、回転軸Bxの回転に伴って移載方向Xに沿う軸心まわりに回転する。従って、回転軸Bxの軸心が係止部Bbの回転軸心Bxaに相当する。 In this embodiment, the locking portion Bb is connected to a rotation axis Bx arranged below the main body portion Bsp of the support member Bs. The rotation axis Bx is arranged along the transfer direction X, and is driven to rotate around an axis along the transfer direction X by the locking drive portion Mb. The locking drive portion Mb is arranged below the main body portion Bsp of the support member Bs, and is fixed to the support member Bs. In this way, the locking portion Bb is supported by the support member Bs via the rotation axis Bx and the locking drive portion Mb. The locking portion Bb rotates around an axis along the transfer direction X as the rotation axis Bx rotates. Therefore, the axis of the rotation axis Bx corresponds to the rotation axis Bxa of the locking portion Bb.
 本実施形態では、係止部Bbは、回転軸心Bxaまわりに回転することで、上述の係止姿勢と非係止姿勢とに姿勢変更する。係止部Bbは、係止姿勢において、その一部が支持部材Bsの本体部Bspよりも上方に突出し(図11参照)、非係止姿勢において、その全部が支持部材Bsの本体部Bspよりも下方に配置される(図10参照)。 In this embodiment, the locking portion Bb rotates around the rotation axis Bxa to change its position between the locking position and the non-locking position. In the locking position, a portion of the locking portion Bb protrudes above the main body portion Bsp of the support member Bs (see FIG. 11), and in the non-locking position, the entire locking portion Bb is positioned below the main body portion Bsp of the support member Bs (see FIG. 10).
 本実施形態では、係止部Bbは、押圧部Baよりも移載方向卸し側X1に配置される。また、係止部Bbと押圧部Baとの移載方向Xの位置関係が固定されている。 In this embodiment, the locking portion Bb is positioned on the lowering side X1 in the transfer direction relative to the pressing portion Ba. In addition, the positional relationship between the locking portion Bb and the pressing portion Ba in the transfer direction X is fixed.
 本実施形態では、係止部Bbは、回転軸心Bxaに直交する方向に沿って延在する棒状又は帯板状に形成されている。図示の例では、係止部Bbは棒状に形成されている。本例では、係止部Bbは、係止姿勢において容器後面部70Rにおける幅方向Yの中央部に位置するように配置されている。これにより、容器後面部70Rにおける幅方向Yの中央部に配置された凹部75に対して、適切な位置に係止部Bbを配置することが可能となっている。 In this embodiment, the locking portion Bb is formed in a rod or strip shape extending along a direction perpendicular to the rotation axis Bxa. In the illustrated example, the locking portion Bb is formed in a rod shape. In this example, the locking portion Bb is arranged so as to be located at the center of the width direction Y of the container rear surface portion 70R in the locked position. This makes it possible to position the locking portion Bb at an appropriate position with respect to the recess 75 arranged at the center of the width direction Y of the container rear surface portion 70R.
 本実施形態では、支持部材Bsに、容器70に対する係止部Bbの相対位置を検出する検出器Seが設けられている。図11に示すように、検出器Seは、容器70に対する係止部Bbの相対位置が係止可能範囲LRにあることを検出する。係止可能範囲LRは、係止部Bbが係止姿勢となった場合に容器70の係止用壁部76に対して移載方向卸し側X1に形成された凹部75に位置するような、容器70に対する係止部Bbの相対位置の範囲である。本例では、係止可能範囲LRは、容器70における周壁部72と係止用壁部76との移載方向Xの離間距離に相当する範囲に設定されている。 In this embodiment, the support member Bs is provided with a detector Se that detects the relative position of the locking portion Bb with respect to the container 70. As shown in FIG. 11, the detector Se detects that the relative position of the locking portion Bb with respect to the container 70 is within the lockable range LR. The lockable range LR is the range of relative positions of the locking portion Bb with respect to the container 70 such that, when the locking portion Bb is in the locking position, it is located in a recess 75 formed on the lowering side X1 in the transfer direction with respect to the locking wall portion 76 of the container 70. In this example, the lockable range LR is set to a range equivalent to the distance in the transfer direction X between the peripheral wall portion 72 and the locking wall portion 76 of the container 70.
 本実施形態において、係止部Bbは、容器70に対する相対位置が規定の係止可能範囲LRにある状態、すなわち、係止部Bbが係止可能範囲LRにあることが検出器Seによって検出された場合に、係止駆動部Mbにより回転駆動されることで、容器70の凹部75に挿入される係止姿勢と、当該凹部75から出る非係止姿勢と、に姿勢変更可能に構成されている。 In this embodiment, when the relative position of the locking portion Bb with respect to the container 70 is within the specified lockable range LR, i.e., when the detector Se detects that the locking portion Bb is within the lockable range LR, the locking portion Bb is rotated by the locking drive portion Mb, so that it can change its position between a locking position in which it is inserted into the recess 75 of the container 70 and a non-locking position in which it comes out of the recess 75.
 規制部Bcは、卸し動作及び掬い動作において、容器70の上下方向への移動を規制するように構成されている。本実施形態では、規制部Bcは、押圧部Baに対して幅方向Yの両側に1つずつ配置されている。 The restricting portion Bc is configured to restrict the upward and downward movement of the container 70 during the unloading and scooping operations. In this embodiment, the restricting portion Bc is disposed on both sides of the pressing portion Ba in the width direction Y.
 図9に示すように、規制部Bcは、卸し動作中(換言すれば、押圧部Baが容器後面部70Rに当接した状態)及び掬い動作中(換言すれば、係止部Bbが凹部75に挿入された状態)において移載用リブ部74に対して上側であって上下方向視で移載用リブ部74と重複する位置に配置される上側押さえ部Bcbを備えている。また、本実施形態において、規制部Bcは、卸し動作中及び掬い動作中に移載用リブ部74に対して下側であって上下方向視で移載用リブ部74と重複する位置に配置される下側押さえ部Bccを更に備えている。 As shown in FIG. 9, the regulating portion Bc has an upper holding portion Bcb that is arranged above the transfer rib portion 74 and overlaps with the transfer rib portion 74 when viewed in the vertical direction during the unloading operation (in other words, when the pressing portion Ba is in contact with the container rear portion 70R) and during the scooping operation (in other words, when the locking portion Bb is inserted into the recess 75). In this embodiment, the regulating portion Bc further has a lower holding portion Bcc that is arranged below the transfer rib portion 74 and overlaps with the transfer rib portion 74 when viewed in the vertical direction during the unloading operation and the scooping operation.
 本実施形態において、上側押さえ部Bcbは、支持部材Bsの本体部Bspの上面から上方に立ち上がるように形成された基部Bcaの上端側から移載方向卸し側X1に向けて延設されている。 In this embodiment, the upper holding portion Bcb extends from the upper end side of the base portion Bca, which is formed to rise upward from the upper surface of the main body portion Bsp of the support member Bs, toward the unloading side X1 in the transfer direction.
 図9に示すように、本実施形態では、移載用リブ部74の上面と上側押さえ部Bcbの下面との設計上の距離を距離D1とし、移載用リブ部74の移載方向Xにおける端面(移載方向掬い側X2の端面)と上側押さえ部Bcbの移載方向Xにおける端面(移載方向卸し側X1の端面)との上下方向視での設計上の距離を距離D2とした場合に、距離D1が距離D2よりも小さい。なお、本実施形態では、距離D1が「リブ部と上側押さえ部との上下方向の距離」に相当し、距離D2が「上下方向視でのリブ部と上側押さえ部との移載方向の重複長さ」に相当する。また、以下において、「設計上の距離」とは、理想どおりの卸し動作及び掬い動作が行われている状態での距離をいうものとする。 As shown in FIG. 9, in this embodiment, if the designed distance between the top surface of the transfer rib portion 74 and the bottom surface of the upper holding portion Bcb is distance D1, and the designed distance in the vertical view between the end face of the transfer rib portion 74 in the transfer direction X (end face on the scooping side X2 in the transfer direction) and the end face of the upper holding portion Bcb in the transfer direction X (end face on the lowering side X1 in the transfer direction) is distance D2, distance D1 is smaller than distance D2. Note that in this embodiment, distance D1 corresponds to the "vertical distance between the rib portion and the upper holding portion," and distance D2 corresponds to the "overlap length in the transfer direction between the rib portion and the upper holding portion as viewed in the vertical direction." In addition, in the following, "design distance" refers to the distance when the lowering and scooping operations are performed as ideal.
 また、図11に示すように、本実施形態では、係止部Bbが係止姿勢である場合における当該係止部Bbの上端面と凹部75の下端(ここでは、凹部75を形成する係止用壁部76の下端面)との移載方向X視での設計上の距離を距離D3とした場合に、距離D1が距離D3よりも小さい。なお、本実施形態では、距離D3が「係止部と凹部との上下方向の重複長さ」に相当する。 Also, as shown in FIG. 11, in this embodiment, if the design distance between the upper end surface of the locking portion Bb and the lower end of the recess 75 (here, the lower end surface of the locking wall portion 76 that forms the recess 75) when viewed in the transfer direction X when the locking portion Bb is in the locking position is defined as distance D3, then distance D1 is smaller than distance D3. Note that in this embodiment, distance D3 corresponds to the "vertical overlap length between the locking portion and the recess."
 ここで、卸し動作時や掬い動作時に振動が生じた場合や容器70に仕切りがあるような場合、容器70内の物品が移載方向Xの一方側に偏って偏荷重が生じることがある。この場合、卸し動作中や掬い動作中に容器後面部70Rの側が容器前面部70Fの側よりも上側に持ち上がるように容器70が傾き、例えば、掬い動作中に係止部Bbが凹部75から抜けて掬い動作を正常に行えないという問題が生じ得る。また、容器70内の物品が幅方向Yの一方側に偏っているような場合には、卸し動作中や掬い動作中に容器70が移載方向Xと平行な軸の回りに回転して容器70が傾き、同様の問題が生じ得る。このように、容器70に意図しない傾きが生じると、卸し動作や掬い動作に支障を来す虞がある。 Here, if vibrations occur during the unloading or scooping operation, or if the container 70 has a partition, the items in the container 70 may be biased to one side of the transfer direction X, resulting in an unbalanced load. In this case, the container 70 may tilt during the unloading or scooping operation so that the rear side 70R of the container is raised higher than the front side 70F of the container, and a problem may arise in which, for example, the locking portion Bb comes out of the recess 75 during the scooping operation and the scooping operation cannot be performed normally. Also, if the items in the container 70 are biased to one side in the width direction Y, the container 70 may rotate around an axis parallel to the transfer direction X during the unloading or scooping operation, causing the container 70 to tilt, resulting in a similar problem. In this way, if the container 70 is unintentionally tilted, there is a risk that the unloading or scooping operation may be hindered.
 本実施形態の搬送装置100では、卸し動作中及び掬い動作中に容器後面部70Rの側が容器前面部70Fの側よりも上側に持ち上がるように容器70が傾きそうになったとしても、規制部Bcにおける上側押さえ部Bcbの下面が移載用リブ部74の上面に当接することで、容器70の移動が上側押さえ部Bcbにより規制される。従って、卸し動作中及び掬い動作中における容器70の姿勢を正しく維持できる。 In the conveying device 100 of this embodiment, even if the container 70 tends to tilt so that the container rear portion 70R is raised higher than the container front portion 70F during the unloading and scooping operations, the lower surface of the upper holding portion Bcb in the regulating portion Bc abuts against the upper surface of the transfer rib portion 74, and the movement of the container 70 is regulated by the upper holding portion Bcb. Therefore, the correct posture of the container 70 can be maintained during the unloading and scooping operations.
 本実施形態において、下側押さえ部Bccは、基部Bcaの下端側から移載方向卸し側X1に向けて延設されている。下側押さえ部Bccの上面は、掬い動作において容器70の移載用リブ部74の下面に当接して容器70を下方から支持することができる。また、下側押さえ部Bccの上面は、卸し動作中及び掬い動作中に容器70が傾いた際に、移載用リブ部74の下面に当接する。 In this embodiment, the lower holding portion Bcc extends from the lower end side of the base portion Bca toward the unloading side X1 in the transfer direction. The upper surface of the lower holding portion Bcc abuts against the lower surface of the transfer rib portion 74 of the container 70 during the scooping operation, thereby supporting the container 70 from below. In addition, the upper surface of the lower holding portion Bcc abuts against the lower surface of the transfer rib portion 74 when the container 70 tilts during the unloading operation and scooping operation.
 図9に示すように、本実施形態において、移載用リブ部74と下側押さえ部Bccとの距離、具体的には移載用リブ部74の下面と下側押さえ部Bccの上面との設計上の距離を距離D4とする。また、移載用リブ部74の移載方向Xにおける端面(移載方向掬い側X2の端面)と下側押さえ部Bccの移載方向Xにおける端面(移載方向卸し側X1の端面)との上下方向視での設計上の距離(換言すれば、上下方向視での移載用リブ部74と下側押さえ部Bccとの移載方向Xの重複長さ)を距離D5とする。本実施形態では、距離D4が距離D5よりも小さい。 As shown in FIG. 9, in this embodiment, the distance between the transfer rib portion 74 and the lower holding portion Bcc, specifically the designed distance between the bottom surface of the transfer rib portion 74 and the top surface of the lower holding portion Bcc, is distance D4. In addition, the designed distance between the end face of the transfer rib portion 74 in the transfer direction X (end face on the scooping side X2 in the transfer direction) and the end face of the lower holding portion Bcc in the transfer direction X (end face on the unloading side X1 in the transfer direction) as viewed in the vertical direction (in other words, the overlap length in the transfer direction X between the transfer rib portion 74 and the lower holding portion Bcc as viewed in the vertical direction) is distance D5. In this embodiment, distance D4 is smaller than distance D5.
 上記のように、偏荷重が生じると、卸し動作中や掬い動作中に容器前面部70Fの側が容器後面部70Rの側よりも上側に持ち上がるように容器70が傾き、例えば、卸し動作中に容器70が載置部材83(具体的には、載置部材83における容器70を案内するガイド部等)に乗り上げ、卸し動作が正常に行えないという問題が生じ得る。 As described above, when an unbalanced load occurs, the container 70 tilts during the unloading or scooping operation so that the container front portion 70F is raised higher than the container rear portion 70R. For example, during the unloading operation, the container 70 may ride up onto the mounting member 83 (specifically, the guide portion that guides the container 70 on the mounting member 83), which may cause a problem that the unloading operation cannot be performed normally.
 本実施形態の搬送装置100では、卸し動作中及び掬い動作中に容器前面部70Fの側が容器後面部70Rの側よりも上側に持ち上がるように容器70が傾きそうになったとしても、規制部Bcにおける下側押さえ部Bccの上面が移載用リブ部74の下面に当接することで、容器70の移動が下側押さえ部Bccにより規制される。従って、卸し動作中及び掬い動作中における容器70の姿勢を正しく維持できる。 In the conveying device 100 of this embodiment, even if the container 70 tends to tilt so that the container front portion 70F is raised higher than the container rear portion 70R during the unloading and scooping operations, the upper surface of the lower holding portion Bcc in the regulating portion Bc abuts against the lower surface of the transfer rib portion 74, and the movement of the container 70 is regulated by the lower holding portion Bcc. Therefore, the correct posture of the container 70 can be maintained during the unloading and scooping operations.
〔掬い動作〕
 次に、図10~図13を参照して、移載装置4による容器70の掬い動作について説明する。なお、図10及び図11は、掬い動作を行う際の移載装置4及び容器70の要部を示す図である。図12は、棚部80に対する容器70の掬い動作を示し、図13は、段積み領域2Aに対する容器70の掬い動作を示している。
[Scooping motion]
Next, the scooping operation of the container 70 by the transfer device 4 will be described with reference to Fig. 10 to Fig. 13. Fig. 10 and Fig. 11 are diagrams showing the main parts of the transfer device 4 and the container 70 when performing the scooping operation. Fig. 12 shows the scooping operation of the container 70 relative to the shelf portion 80, and Fig. 13 shows the scooping operation of the container 70 relative to the stacking area 2A.
 図10に示すように、移載装置4は、掬い動作を行う場合に、係止部Bbを、非係止姿勢とした状態で係止可能範囲LRに配置する。本実施形態では、移載装置4は、押圧部Ba、係止部Bb、及び規制部Bcを移載方向卸し側X1へ一体的に移動させることで、係止部Bbを係止可能範囲LRに配置する。移載装置4は、押圧部Ba、係止部Bb、及び規制部Bcの移載方向卸し側X1への移動を、移載駆動部Msによって支持部材Bsを駆動することにより行う。係止部Bbが係止可能範囲LRに配置されたか否かは、検出器Seによる検出結果に基づいて判断される。なお、規制部Bcは、係止部Bbが係止可能範囲LRにある状態で、下側押さえ部Bccが移載用リブ部74の下面に対して下方から対向する位置に配置される。 As shown in FIG. 10, when performing a scooping operation, the transfer device 4 places the locking portion Bb in the lockable range LR in a non-locking position. In this embodiment, the transfer device 4 moves the pressing portion Ba, the locking portion Bb, and the regulating portion Bc integrally toward the lowering side X1 in the transfer direction to place the locking portion Bb in the lockable range LR. The transfer device 4 moves the pressing portion Ba, the locking portion Bb, and the regulating portion Bc toward the lowering side X1 in the transfer direction by driving the support member Bs with the transfer drive portion Ms. Whether the locking portion Bb is placed in the lockable range LR is determined based on the detection result by the detector Se. Note that the regulating portion Bc is placed in a position where the lower pressing portion Bcc faces the lower surface of the transfer rib portion 74 from below when the locking portion Bb is in the lockable range LR.
 図11に示すように、移載装置4は、検出器Seによって係止部Bbが係止可能範囲LRに配置されたことが検出された場合に、係止部Bbを非係止姿勢から係止姿勢に姿勢変更させる。移載装置4は、係止部Bbの姿勢変更を、係止駆動部Mbによって係止部Bbを駆動することにより行う。図11に示すように、係止部Bbが係止姿勢になると、係止部Bbと押圧部Baとが、容器70の係止用壁部76を挟んで移載方向Xの両側に分かれて配置された状態となる。また、本実施形態では、係止部Bbが係止姿勢になった際に、換言すれば、係止部Bbが凹部75に挿入された状態になった際に、距離D1が距離D2よりも小さく、且つ、距離D4が距離D5よりも小さくなるように、規制部Bcの上側押さえ部Bcbと下側押さえ部Bccとの間に移載用リブ部74が位置した状態となる(図9も参照)。また、本実施形態では、係止部Bbが係止姿勢になった際に、距離D1が距離D3よりも小さい状態となる。 11, when the detector Se detects that the locking portion Bb is positioned within the lockable range LR, the transfer device 4 changes the position of the locking portion Bb from the non-locking position to the locking position. The transfer device 4 changes the position of the locking portion Bb by driving the locking portion Bb with the locking drive unit Mb. As shown in FIG. 11, when the locking portion Bb is in the locking position, the locking portion Bb and the pressing portion Ba are arranged separately on both sides of the locking wall portion 76 of the container 70 in the transfer direction X. In addition, in this embodiment, when the locking portion Bb is in the locking position, in other words, when the locking portion Bb is inserted into the recess 75, the transfer rib portion 74 is positioned between the upper holding portion Bcb and the lower holding portion Bcc of the regulating portion Bc such that the distance D1 is smaller than the distance D2 and the distance D4 is smaller than the distance D5 (see also FIG. 9). Furthermore, in this embodiment, when the locking portion Bb is in the locking position, the distance D1 is smaller than the distance D3.
 ついで、棚部80に対する容器70の掬い動作を行う場合、図12に示すように、移載装置4は、押圧部Ba、係止部Bb、及び規制部Bcを移載方向掬い側X2へ一体的に移動させることで、係止部Bbを移載方向掬い側X2へ移動させ、容器70を移載方向掬い側X2へ引き込む。すなわち、移載装置4は、係止姿勢の係止部Bbを、移載駆動部Msにより移載方向掬い側X2へ移動させることで、容器70の掬い動作を行う。 Next, when scooping the container 70 onto the shelf 80, as shown in FIG. 12, the transfer device 4 moves the pressing portion Ba, the locking portion Bb, and the regulating portion Bc integrally toward the scooping side X2 in the transfer direction, thereby moving the locking portion Bb toward the scooping side X2 in the transfer direction and pulling the container 70 into the scooping side X2 in the transfer direction. In other words, the transfer device 4 moves the locking portion Bb in the locking position toward the scooping side X2 in the transfer direction by the transfer drive portion Ms, thereby performing the scooping operation of the container 70.
 一方、段積み領域2Aに対する容器70の掬い動作を行う場合には、移載装置4は、移載用リブ部74の下面に対して下方から対向する位置に配置された規制部Bcを上昇させて、当該規制部Bcの下側押さえ部Bccの上面を移載用リブ部74の下面に当接させて、移載用リブ部74を持ち上げる。これにより、図13に示すように、容器後面部70Rが持ち上げられ、掬い対象の容器70の嵌合部77における移載方向掬い側X2の端部が、その下の段に配置された容器70の開口部71から上方に離間する。その後、棚部80に対する容器70の掬い動作を行う場合と同様に、移載装置4は、押圧部Ba、係止部Bb、及び規制部Bcを移載方向掬い側X2へ一体的に移動させることで、係止部Bbを移載方向掬い側X2へ移動させ、容器70を移載方向掬い側X2へ引き込む。 On the other hand, when scooping a container 70 into the stacked area 2A, the transfer device 4 raises the regulating part Bc, which is positioned facing the lower surface of the transfer rib part 74 from below, and abuts the upper surface of the lower holding part Bcc of the regulating part Bc against the lower surface of the transfer rib part 74, thereby lifting the transfer rib part 74. As a result, as shown in Figure 13, the container rear part 70R is raised, and the end part of the fitting part 77 of the container 70 to be scooped on the transfer direction scooping side X2 moves upward away from the opening 71 of the container 70 arranged in the tier below. Thereafter, in the same manner as when scooping the container 70 onto the shelf 80, the transfer device 4 moves the pressing part Ba, the locking part Bb, and the regulating part Bc integrally toward the scooping side X2 in the transfer direction, thereby moving the locking part Bb toward the scooping side X2 in the transfer direction and pulling the container 70 into the scooping side X2 in the transfer direction.
 以上のようにして、容器70の掬い動作が行われる。当該掬い動作は、制御装置C(図5参照)が搬送装置100の各機能部を制御することにより行われる。 In this manner, the scooping operation of the container 70 is performed. The scooping operation is performed by the control device C (see FIG. 5) controlling each functional part of the conveying device 100.
〔卸し動作〕
 次に、図14~図16を参照して、移載装置4による容器70の卸し動作について説明する。なお、図14は、卸し動作を行う際の移載装置4及び容器70の要部を示す図である。図15は、棚部80に対する容器70の卸し動作を示し、図16は、段積み領域2Aに対する容器70の卸し動作を示している。
[Unloading operation]
Next, the unloading operation of the container 70 by the transfer device 4 will be described with reference to Fig. 14 to Fig. 16. Fig. 14 is a diagram showing the main parts of the transfer device 4 and the container 70 when performing the unloading operation. Fig. 15 shows the unloading operation of the container 70 on the shelf section 80, and Fig. 16 shows the unloading operation of the container 70 on the stacking area 2A.
 図14に示すように、移載装置4は、卸し動作を行う場合に、押圧部Baを、容器後面部70Rに当接させ、当該押圧部Baにより容器70を移載方向卸し側X1へ向けて押圧する。本例では、移載装置4は、押圧部Baを、容器70の係止用壁部76に当接させて押圧する。なお、本実施形態では、押圧部Baが係止用壁部76に当接した状態になった際に、距離D1が距離D2よりも小さく、且つ、距離D4が距離D5よりも小さくなるように、規制部Bcの上側押さえ部Bcbと下側押さえ部Bccとの間に移載用リブ部74が位置した状態となる。 As shown in FIG. 14, when the transfer device 4 performs an unloading operation, the pressing part Ba abuts against the rear surface 70R of the container, and the pressing part Ba presses the container 70 toward the unloading side X1 in the transfer direction. In this example, the transfer device 4 presses the pressing part Ba against the locking wall part 76 of the container 70. Note that in this embodiment, when the pressing part Ba abuts against the locking wall part 76, the transfer rib part 74 is positioned between the upper pressing part Bcb and the lower pressing part Bcc of the regulating part Bc so that the distance D1 is smaller than the distance D2 and the distance D4 is smaller than the distance D5.
 本実施形態では、棚部80に対する容器70の卸し動作を行う場合、図15に示すように、移載装置4は、容器70の係止用壁部76に押圧部Baを当接させた状態で、押圧部Ba、係止部Bb、及び規制部Bcを移載方向卸し側X1へ一体的に移動させることで、押圧部Baを移載方向卸し側X1へ移動させる。 In this embodiment, when the container 70 is unloaded from the shelf 80, as shown in FIG. 15, the transfer device 4 moves the pressing part Ba to the unloading side X1 in the transfer direction by moving the pressing part Ba, the locking part Bb, and the regulating part Bc together while the pressing part Ba is in contact with the locking wall 76 of the container 70.
 一方、段積み領域2Aに対する容器70の卸し動作を行う場合、図16に示すように、移載装置4は、容器70の係止用壁部76に押圧部Baを当接させた状態で、押圧部Ba、係止部Bb、及び規制部Bcを移載方向卸し側X1へ一体的に移動させることで、押圧部Baを移載方向卸し側X1へ移動させる。本例では、移載装置4は、段積み領域2Aにおける卸し先となる容器70よりも上方の位置で、卸し対象の容器70を移載方向卸し側X1へ向けて押圧する。そして、卸し対象の容器70が保持部Aよりも移載方向卸し側X1へ突出することで当該容器70が保持部Aによる支持を失って段積み領域2Aにおいて下降すると、移載装置4は、規制部Bcの下側押さえ部Bccによって移載用リブ部74の下面を支持する状態となる。これにより、卸し対象の容器70における容器後面部70Rが規制部Bcの下側押さえ部Bccによって支持される。その後、規制部Bcを下降させることで、卸し対象の容器70が、卸し先となる容器70に対して上方から嵌合する。これにより、卸し対象の容器70が段積み領域2Aに段積みされる。 On the other hand, when unloading a container 70 into the stacking area 2A, as shown in FIG. 16, the transfer device 4 moves the pressing part Ba to the unloading side X1 in the transfer direction by moving the pressing part Ba, the locking part Bb, and the regulating part Bc integrally toward the unloading side X1 in the transfer direction while abutting the pressing part Ba against the locking wall part 76 of the container 70. In this example, the transfer device 4 presses the container 70 to be unloaded toward the unloading side X1 in the transfer direction at a position above the destination container 70 in the stacking area 2A. Then, when the container 70 to be unloaded protrudes beyond the holding part A toward the unloading side X1 in the transfer direction and loses support from the holding part A and descends in the stacking area 2A, the transfer device 4 is in a state where the lower surface of the transfer rib part 74 is supported by the lower holding part Bcc of the regulating part Bc. As a result, the rear surface 70R of the container 70 to be unloaded is supported by the lower pressing portion Bcc of the restricting portion Bc. The restricting portion Bc is then lowered so that the container 70 to be unloaded fits from above into the container 70 that is to be unloaded. As a result, the container 70 to be unloaded is stacked in the stacking area 2A.
 以上のようにして、容器70の卸し動作が行われる。当該卸し動作は、制御装置C(図5参照)が搬送装置100の各機能部を制御することにより行われる。 In this manner, the unloading operation of the container 70 is performed. The unloading operation is performed by the control device C (see FIG. 5) controlling each functional part of the conveying device 100.

[Summary of the above embodiment]
The above-described transport vehicle will now be described.
 容器を搬送する搬送装置であって、
 前記容器を保持する保持部を有する移載装置を備え、
 前記移載装置は、水平方向に沿う移載方向に沿って前記容器を移動させて、前記保持部から移載対象箇所へ前記容器を移載する卸し動作、及び前記移載対象箇所から前記保持部へ前記容器を移載する掬い動作を含む移載動作を行うように構成され、
 前記移載方向における前記保持部から前記移載対象箇所へ向かう側を移載方向卸し側、前記移載方向における前記移載対象箇所から前記保持部へ向かう側を移載方向掬い側とし、上下方向視で前記移載方向に直交する方向を幅方向とし、前記容器における前記移載方向卸し側を向く部分を容器前面部、前記容器における前記移載方向掬い側を向く部分を容器後面部として、
 前記移載装置は、前記卸し動作において前記容器を押圧する押圧部と、前記掬い動作において前記容器に係止される係止部と、前記押圧部及び前記係止部に対して前記幅方向の少なくとも一方側に配置されて前記卸し動作及び前記掬い動作における前記容器の上下動を規制する規制部と、前記押圧部、前記係止部、及び前記規制部を前記移載方向に沿って往復移動させる移載駆動部と、を備え、
 前記容器後面部に、下側に向かって開口する凹部と、前記移載方向掬い側に突出すると共に前記容器後面部に沿って水平方向に延在するように形成されたリブ部と、が設けられ、
 前記移載装置は、前記押圧部を、前記容器後面部に当接させた状態で前記移載駆動部により前記移載方向卸し側へ移動させることで、前記卸し動作を行い、前記係止部を、前記凹部に対して下側から挿入した状態で前記移載駆動部により前記移載方向掬い側へ移動させることで、前記掬い動作を行い、
 前記規制部は、前記卸し動作中及び前記掬い動作中に前記リブ部に対して上側であって上下方向視で前記リブ部と重複する位置に配置される上側押さえ部を備える。
A conveying device for conveying a container,
A transfer device having a holding part for holding the container,
The transfer device is configured to move the container along a horizontal transfer direction to perform a transfer operation including a lowering operation for transferring the container from the holding unit to a transfer target location, and a scooping operation for transferring the container from the transfer target location to the holding unit,
The side from the holding unit to the target location in the transfer direction is the unloading side in the transfer direction, the side from the target location to the holding unit in the transfer direction is the scooping side in the transfer direction, the direction perpendicular to the transfer direction when viewed in the up-down direction is the width direction, the part of the container facing the unloading side in the transfer direction is the container front part, and the part of the container facing the scooping side in the transfer direction is the container rear part,
The transfer device includes a pressing unit that presses the container during the unloading operation, a locking unit that locks onto the container during the scooping operation, a regulating unit that is disposed on at least one side of the pressing unit and the locking unit in the width direction and that regulates the up and down movement of the container during the unloading operation and the scooping operation, and a transfer drive unit that reciprocates the pressing unit, the locking unit, and the regulating unit along the transfer direction,
The rear surface of the container is provided with a recess that opens downward and a rib portion that protrudes toward the scooping side in the transfer direction and extends horizontally along the rear surface of the container,
The transfer device performs the unloading operation by moving the pressing part toward the unloading side in the transfer direction by the transfer drive part while the pressing part is in contact with the rear surface part of the container, and performs the scooping operation by moving the locking part toward the scooping side in the transfer direction by the transfer drive part while the locking part is inserted into the recess from below,
The regulating portion includes an upper pressing portion that is arranged above the rib portion and at a position overlapping with the rib portion when viewed in the up-down direction during the unloading operation and the scooping operation.
 本構成によれば、卸し動作中及び掬い動作中に容器後面部の側が容器前面部の側よりも上側に持ち上がりそうになった場合には、上昇しようとするリブ部の移動が上側押さえ部により規制される。従って、卸し動作中及び掬い動作中における容器の姿勢を正しく維持し易い。そのため、例えば容器に収容された物品の重心位置に移載方向の偏りがある場合でも、容器後面部が持ち上がった状態になり難くすることができる。 With this configuration, if the rear side of the container is about to rise higher than the front side of the container during the unloading and scooping operations, the movement of the rib portion attempting to rise is restricted by the upper retaining portion. This makes it easier to maintain the correct position of the container during the unloading and scooping operations. Therefore, for example, even if the center of gravity of the item contained in the container is biased in the transfer direction, it is possible to prevent the rear side of the container from becoming lifted.
 ここで、一対の前記規制部が、前記押圧部及び前記係止部に対して前記幅方向の両側に分かれて配置されている、と好適である。 In this case, it is preferable that the pair of restricting portions are arranged separately on both sides of the pressing portion and the locking portion in the width direction.
 本構成によれば、一対の規制部により、押圧部及び係止部に対して幅方向の両側でリブ部の上下動を規制することができる。従って、容器の幅方向の傾きも小さく抑え易い。 With this configuration, the pair of regulating parts can regulate the up and down movement of the rib part on both sides of the width direction relative to the pressing part and the locking part. Therefore, it is easy to keep the inclination of the container in the width direction small.
 また、前記卸し動作中及び前記掬い動作中における前記リブ部と前記上側押さえ部との上下方向の距離は、上下方向視での前記リブ部と前記上側押さえ部との前記移載方向の重複長さよりも小さい、と好適である。 Furthermore, it is preferable that the vertical distance between the rib portion and the upper holding portion during the unloading operation and the scooping operation is smaller than the overlap length in the transfer direction between the rib portion and the upper holding portion when viewed in the vertical direction.
 本構成によれば、卸し動作中及び掬い動作中に容器後面部の側が容器前面部の側よりも上側に持ち上がりそうになった場合にリブ部の移動を上側押さえ部により適切に規制できる。従って、卸し動作中及び掬い動作中における容器の姿勢を正しく維持し易い。 With this configuration, if the rear side of the container is about to rise higher than the front side of the container during the unloading and scooping operations, the movement of the rib portion can be appropriately restricted by the upper retaining portion. Therefore, it is easy to maintain the correct position of the container during the unloading and scooping operations.
 また、前記卸し動作中及び前記掬い動作中における前記リブ部と前記上側押さえ部との上下方向の距離は、前記係止部と前記凹部との上下方向の重複長さよりも小さい、と好適である。 Furthermore, it is preferable that the vertical distance between the rib portion and the upper holding portion during the unloading operation and the scooping operation is smaller than the vertical overlap length between the locking portion and the recess.
 本構成によれば、卸し動作中及び掬い動作中に容器後面部の側が容器前面部の側よりも上側に持ち上がりそうになった場合にリブ部の移動を上側押さえ部により適切に規制できる。従って、卸し動作中及び掬い動作中における容器の姿勢を正しく維持し易い。 With this configuration, if the rear side of the container is about to rise higher than the front side of the container during the unloading and scooping operations, the movement of the rib portion can be appropriately restricted by the upper retaining portion. Therefore, it is easy to maintain the correct position of the container during the unloading and scooping operations.
 また、前記移載装置は、前記押圧部とは別に前記係止部を駆動して当該係止部に姿勢変更を行わせる係止駆動部を更に備え、
 前記係止部は、前記容器に対する相対位置が規定の係止可能範囲にある状態で前記係止駆動部により駆動されることで、前記凹部に挿入される係止姿勢と、前記凹部から出る非係止姿勢と、に姿勢変更可能であり、
 前記掬い動作中は、前記係止部を前記係止姿勢とする、と好適である。
The transfer device further includes a locking drive unit that drives the locking unit separately from the pressing unit to change the position of the locking unit,
the locking portion is driven by the locking drive portion in a state where a relative position of the locking portion with respect to the container is within a specified lockable range, so that the locking portion can be changed in position between a locking position where the locking portion is inserted into the recess and a non-locking position where the locking portion is removed from the recess,
It is preferable that the locking portion is in the locking position during the scooping operation.
 本構成によれば、係止部が姿勢変更を行うことにより、係止部を凹部に挿入した状態と、係止部が凹部に挿入されていない状態との双方を容易に実現できる。従って、掬い動作のために係止部を移載方向卸し側に移動させ、係止部を凹部に挿入し、係止部を移載方向掬い側に移動させて掬い動作を行うという一連の動きを円滑に行うことができる。 With this configuration, the locking part can change its position to easily achieve both a state in which the locking part is inserted into the recess and a state in which the locking part is not inserted into the recess. Therefore, a series of movements can be smoothly performed in which the locking part is moved to the unloading side in the transfer direction for the scooping operation, the locking part is inserted into the recess, and the locking part is moved to the scooping side in the transfer direction to perform the scooping operation.
 また、前記規制部は、前記卸し動作中及び前記掬い動作中に前記リブ部に対して下側であって上下方向視で前記リブ部と重複する位置に配置される下側押さえ部をさらに備える、と好適である。 It is also preferable that the regulating portion further includes a lower pressing portion that is positioned below the rib portion and overlaps with the rib portion when viewed in the up-down direction during the unloading operation and the scooping operation.
 本構成によれば、卸し動作中及び掬い動作中に容器前面部の側が容器後面部の側よりも上側に持ち上がりそうになった場合には、反対に下降しようとするリブ部の移動が下側押さえ部により規制される。従って、卸し動作中及び掬い動作中における容器の姿勢を正しく維持し易い。 With this configuration, if the front side of the container is about to rise higher than the rear side of the container during the unloading and scooping operations, the movement of the rib portion that attempts to descend is restricted by the lower pressing portion. This makes it easier to maintain the correct position of the container during the unloading and scooping operations.
