Description
本発明は、物品を載置支持する物品載置面を有する上部部材及び前記上部部材から下方に離間して設けられる下部部材を備えて構成される物品載置具に関する。 The present invention relates to an article placement tool including an upper member having an article placement surface for placing and supporting an article, and a lower member provided to be spaced downward from the upper member.
かかる物品載置具は、上部部材の上面側に形成される物品載置面に物品を載置支持するように構成されている。そして、物品を物品載置面に載置支持した状態で物品収納箇所に収納されるとともに、当該物品を処理箇所で処理すべく物品収納箇所から取り出す必要が生じた場合には、物品を載置支持した物品載置具を、例えばフォーク式の載置具搬送装置で移載箇所まで搬送し、移載箇所にて物品載置面に載置支持される物品を移載対象部に移載するように構成されている。 Such an article placement tool is configured to place and support an article on an article placement surface formed on the upper surface side of the upper member. The article is stored in the article storage location in a state where the article is placed and supported on the article placement surface, and the article is placed when it is necessary to take out the article from the article storage location to be processed at the processing location. The supported article placement tool is transported to a transfer location by, for example, a fork-type placement tool transport device, and the article placed and supported on the article placement surface is transferred to the transfer target portion at the transfer location. It is configured as follows.
このように、移載箇所にて物品載置具に載置支持した物品を物品載置具から移載対象部に移載する方法として、従来、物品を吊下げ装置にて吊下げ状態とし、当該物品を物品載置面から上方に浮上させた状態で物品載置具から移載対象部に移動させる方法が用いられていたが、移載箇所に載置した物品載置具と移載対象部との間での物品の移載作業を吊下げ装置にて行なう場合は、物品を吊下げ装置に吊下げ状態にセットし、そのセットした物品を吊下げ装置にて吊下げ状態で移動させ、次に、物品を吊下げ装置から外すことを行うものであり、吊下げ装置にて物品を移載する際には、吊下げ装置にて物品を吊下げ状態で移動させる作業が必要となるばかりでなく、物品を吊下げ装置にセットする作業や物品を吊下げ装置から外す作業を要するものであり、移載箇所に載置された物品載置具と移載対象部との間での物品の移載のため作業が煩雑であり、作業性が悪いものとなっていた。 Thus, as a method of transferring the article placed and supported on the article placement tool at the transfer place from the article placement tool to the transfer target part, conventionally, the article is suspended by the suspension device, Although the method of moving the article from the article placement tool to the transfer target part in a state where the article is lifted upward from the article placement surface, the article placement tool placed at the transfer location and the transfer target are used. When the article is transferred to and from the section using the hanging device, the article is set in the hanging state on the hanging device, and the set article is moved in the hanging state by the hanging device. Next, the article is removed from the suspension device, and when the article is transferred by the suspension device, an operation for moving the article in a suspended state by the suspension device is required. In addition to the work of setting the article on the suspension device and the work of removing the article from the suspension device are required. Is intended, work for transferring the article between the mounted article placement base and transfer target portion in transfer location is complicated, it had become a poor workability.
そこで、移載箇所に載置された物品載置具と移載対象部との間での物品の移載作業を簡易にするために、物品の底部に当接して物品を水平方向に移動自在に載置支持するローラを上端に備えた物品支持体を、上記ローラを載置具支持台に載せられた物品載置具よりも下方に位置させる退避状態と、ローラを物品載置具に開口形成された挿通部を通して上方に移行させて物品載置具の上方に位置させる物品支持作用状態とに昇降自在に載置具支持台に設けるように構成し、上記物品支持体を物品支持作用状態に切換えることによって、作業者の手作業等で物品を移載方向に沿って押し移動させて、物品載置具と移載対象部との間での物品の移載のための作業を簡易にするものが提案されている（例えば、特許文献１参照）。 Therefore, in order to simplify the transfer operation of the article between the article placement tool placed at the transfer location and the transfer target part, the article can be moved in the horizontal direction by contacting the bottom of the article. A retreating state in which the article support body provided with a roller for placing and supporting it on the upper end is positioned below the article placing tool placed on the placing tool support base, and the roller is opened to the article placing tool. The article support is configured to be provided on the placement tool support base so as to be movable up and down to the article support action state that moves upward through the formed insertion portion and is positioned above the article placement tool. By switching to, the article is pushed and moved along the transfer direction by an operator's manual work, etc., and the work for transferring the article between the article placement tool and the transfer target part is simplified. Have been proposed (see, for example, Patent Document 1).
しかしながら、上記特許文献１は、物品支持体を退避状態から物品支持作用状態に切換える場合に、物品支持体を物品載置具の底面に開口形成された挿通部へ下方から挿通して上方に移動させ、ローラの上端が物品載置具の底面よりも下方に位置する状態からローラの上端が物品載置具の上方に位置に位置する状態となるまで上昇移動させる必要がある。つまり、物品支持体を退避状態から物品支持作用状態とするためには、物品載置具の上下方向の幅（厚さ）と、ローラの上端から物品載置具の底面までの間隔とを合計したストロークが必要になる。 However, in Patent Document 1, when the article support is switched from the retracted state to the article support working state, the article support is inserted from below into the insertion portion formed in the bottom surface of the article placement tool and moved upward. It is necessary to move the roller from the state where the upper end of the roller is located below the bottom surface of the article placement tool until the upper end of the roller is located above the article placement tool. That is, in order to change the article support from the retracted state to the article support working state, the vertical width (thickness) of the article placement tool and the distance from the upper end of the roller to the bottom surface of the article placement tool are totaled. Stroke is required.
そのため、物品支持体を退避状態から物品支持作用状態とすべく上昇移動させるために必要な移動距離が長くなるので、その移動に要する時間が長くなり、作業効率が低下する虞があった。 For this reason, since the moving distance required to move the article support upward from the retracted state to the article supporting action state becomes long, the time required for the movement becomes long, and the working efficiency may be lowered.
本発明は、上記実情に鑑みてなされたものであり、その目的は、作業効率の低下を抑制することが可能な物品載置具を提供することにある。 This invention is made | formed in view of the said situation, The objective is to provide the article mounting tool which can suppress the fall of work efficiency.
上記課題を解決するための本発明に係る物品載置具の第１特徴構成は、物品を載置支持する物品載置面を有する上部部材及び前記上部部材から下方に離間して設けられる下部部材を備えて構成される物品載置具であって、
物品の底部に当接して物品を搬送自在に載置支持する可動ローラと、その可動ローラを搬送方向に直交する向きに沿う水平軸心周りに回転自在に支持しかつ前記上部部材に対して前記可動ローラと一体昇降自在なローラ支持体が設けられ、前記ローラ支持体が、前記可動ローラの上端が前記物品載置面と前記下部部材との間に位置する下降位置と、前記可動ローラの上端が前記物品載置面よりも上方に位置する上昇位置とに切換え自在に構成され、かつ、前記ローラ支持体に下方側から当接する押し上げ部材と前記上部部材との相対距離を近接状態とすることにより、前記ローラ支持体が前記上昇位置に位置する移載作用状態とし、前記押し上げ部材と前記上部部材との相対距離を離間状態とすることにより、前記ローラ支持体が前記下降位置に位置する退避状態とするように切換え自在に構成されている点にある。
The first characteristic configuration of the article placement tool according to the present invention for solving the above problems includes an upper member having an article placement surface for placing and supporting the article, and a lower member provided to be spaced downward from the upper member. An article placement tool configured to include:
A movable roller that abuts the bottom of the article and supports the article so that the article can be conveyed, and supports the movable roller rotatably about a horizontal axis along a direction orthogonal to the conveying direction and the upper member A roller support that can be moved up and down integrally with the movable roller is provided, and the roller support includes a lowered position where the upper end of the movable roller is located between the article placement surface and the lower member, and the upper end of the movable roller. Can be switched to a raised position located above the article placement surface, and the relative distance between the push-up member that comes into contact with the roller support body from below is close to the upper member. Thus, the roller support is brought into a transfer operation state where the roller support is located at the raised position, and the relative distance between the push-up member and the upper member is separated, so that the roller support is moved to the lowered position. In that it is switched freely configured to the retracted state located.
すなわち、ローラ支持体が下降位置に位置する退避状態においては、可動ローラの上端が物品載置面と下部部材との間に位置するため、可動ローラの上端は物品載置面よりも下方側位置に存在することとなり、物品はその底部が物品載置具の物品載置面に当接する状態で載置支持される。また、ローラ支持体が上昇位置に位置する移載作用状態においては、可動ローラの上端が物品載置面よりも上方に位置するため、物品はその底部が可動ローラの上端に当接する状態で載置支持される。 That is, in the retracted state where the roller support is in the lowered position, the upper end of the movable roller is located between the article placement surface and the lower member, and therefore the upper end of the movable roller is positioned below the article placement surface. Thus, the article is placed and supported in a state where the bottom of the article is in contact with the article placing surface of the article placing tool. Further, in the transfer operation state in which the roller support is located at the raised position, the upper end of the movable roller is positioned above the article placement surface, so that the article is loaded with its bottom part in contact with the upper end of the movable roller. It is supported.
したがって、物品載置具を、例えば物品収納箇所に収納している場合や、物品収納箇所から移載箇所に搬送する搬送作業中である場合においては、ローラ支持体に下方側から当接する押し上げ部材と上部部材との相対距離を離間状態としてローラ支持体を下降位置に切り換えて退避状態とし、物品載置具に載置支持される物品と物品載置面と間の摩擦抵抗により物品の物品載置具上での移動が阻害される状態で安定して物品を載置支持することができる。 Therefore, when the article placement tool is housed in, for example, the article storage place or when the article placement tool is being transported from the article storage place to the transfer place, the push-up member that contacts the roller support from below The relative distance between the upper member and the upper member is changed to the retracted state by switching the roller support to the lowered position, and the article is placed on the article by the frictional resistance between the article placed and supported on the article placing tool and the article placing surface. The article can be stably placed and supported in a state in which movement on the fixture is inhibited.
また、移載箇所にて当該物品を物品載置具から移載対象部に移載する場合においては、前記押し上げ部材と上部部材との相対距離を近接状態としてローラ支持体を上昇位置に切り換えて移載作用状態とし、物品の底部を可動ローラに載置支持させて摩擦抵抗を低減することにより作業者の手作業等により容易に物品載置具から移載対象部に対して物品を移載することができるものとなる。 Further, when transferring the article from the article placement tool to the transfer target portion at the transfer location, the roller support is switched to the raised position with the relative distance between the push-up member and the upper member being in the proximity state. By transferring and placing the bottom of the article on the movable roller and supporting it to reduce frictional resistance, the article can be easily transferred from the article placement tool to the transfer target part by manual operation of the operator. Will be able to do.
そして、そのように退避状態と移載作用状態とを切換えるにあたり、退避状態においては、ローラ支持体に支持される可動ローラの上端が物品載置面と下部部材との間に位置するように構成されているから、ローラ支持体を下降位置から上昇位置に切換えるために押し上げ部材を上昇移動させるにしても、その上昇移動量を、例えば可動ローラの上端を物品載置具の下部部材の底面よりも下方から物品載置面よりも上方に突出させるべくローラ支持体を上昇移動させる場合の移動量よりも十分に小さな移動量とすることができるものとなり、作業効率の低下を抑制することが可能な物品載置具を提供することができる。 When switching between the retracted state and the transfer action state, the upper end of the movable roller supported by the roller support is configured to be positioned between the article placement surface and the lower member in the retracted state. Therefore, even if the push-up member is moved upward to switch the roller support from the lowered position to the raised position, the upward movement amount is, for example, the upper end of the movable roller from the bottom surface of the lower member of the article mounting tool. In addition, the amount of movement can be made sufficiently smaller than the amount of movement when the roller support is moved upward to project upward from the article placement surface from below, and it is possible to suppress a decrease in work efficiency. It is possible to provide a simple article placement tool.
本発明に係る物品載置具の第２特徴構成は、上記第１特徴構成に加えて、前記可動ローラが、搬送方向に沿って複数並べて設けられ、前記ローラ支持体が、複数の前記可動ローラを搬送方向に並ぶ状態で一体昇降自在に支持するように構成されている点にある。 According to a second characteristic configuration of the article placing tool according to the present invention, in addition to the first characteristic configuration, a plurality of the movable rollers are provided side by side along a conveying direction, and the roller support is a plurality of the movable rollers. Are arranged so as to be movable up and down integrally in a state of being aligned in the transport direction.
すなわち、上記のように物品の底部に可動ローラを当接させて物品を搬送するためには、複数の可動ローラによって物品の底部の複数の部分を支持して、その姿勢を安定させるとともに、１つの可動ローラにかかる負荷を低減させることが好ましい。
しかしながら、可動ローラを搬送方向に沿って複数並べて設けるにあたり、それら複数の可動ローラを複数のローラ支持体に個別に支持させる構成とすると、退避状態と移載作用状態とを切換えために、押し上げ部材を可動ローラの数に対応して設ける必要があり、物品載置具及び押し上げ部材の構成が複雑になる虞がある。また、押し上げ部材が、物品載置具の下部部材に設けられた挿通孔を貫通する状態でローラ支持体に下方側から当接する構成とする場合には、当該下部部材に複数の挿通孔を設ける必要があるため、下部部材の強度が低下する虞がある。
第２特徴構成によれば、ローラ支持体が、複数の可動ローラを搬送方向に並ぶ状態で支持するように構成されるものであるから、上記の如き押し上げ部材又は押し上げ部材を挿通する挿通孔の数を少なくすることができ、構成を簡略化するとともに、下部部材の強度を向上することができる。
That is, as described above, in order to bring the movable roller into contact with the bottom of the article and convey the article, a plurality of portions of the bottom of the article are supported by the plurality of movable rollers, and the posture is stabilized. It is preferable to reduce the load applied to the two movable rollers.
However, when a plurality of movable rollers are arranged side by side along the transport direction, a push-up member is used to switch between the retracted state and the transfer action state when the plurality of movable rollers are individually supported by a plurality of roller supports. Need to be provided corresponding to the number of movable rollers, and the configuration of the article placement tool and the push-up member may be complicated. Further, when the push-up member is configured to contact the roller support body from below while penetrating the insertion hole provided in the lower member of the article mounting tool, a plurality of insertion holes are provided in the lower member. Since it is necessary, the strength of the lower member may be reduced.
According to the second characteristic configuration, the roller support is configured to support the plurality of movable rollers in a state of being aligned in the transport direction, and therefore the push-up member or the insertion hole through which the push-up member is inserted as described above. The number can be reduced, the structure can be simplified, and the strength of the lower member can be improved.
本発明に係る物品載置具の第３特徴構成は、上記第１又は第２特長構成に加えて、平面視において、前記ローラ支持体に支持される複数の可動ローラの並び方向外方側に、上端が前記物品載置面よりも上方に位置する高さで上下位置が固定された位置固定ローラが設けられている点にある。 In addition to the first or second feature configuration, the third feature configuration of the article placement tool according to the present invention is on the outer side in the arrangement direction of the plurality of movable rollers supported by the roller support in a plan view. A position fixing roller is provided in which the upper and lower positions are fixed at a height at which the upper end is positioned above the article placement surface.
すなわち、ローラ支持体に支持される複数の可動ローラの並び方向外方側、つまり、物品載置具の平面視における移載方向端部となる部分にもローラ支持体を位置させる状態とすると、上部部材と下部部材とを連結する桁部材をその部分に設けることができないため、移載方向端部における物品載置具の強度が低下する虞がある。しかしながら、物品載置具の平面視における移載方向端部にローラ支持体が存在しないように構成すると、移載方向端部には可動ローラが存在しないことになり、移載方向端部に可動ローラの上端部よりも低い位置に位置する物品載置面が継続する状態となるため、物品を移載対象部との間で移載するときに、物品をスムーズに（がたつきのない状態で）移載できない虞がある。
第３特徴構成によれば、上端が物品載置面よりも上方に位置する高さ（ローラ支持体が上昇位置に位置するときの可動ローラの上端の高さと略同じであることが好ましい）で上下位置が固定された位置固定ローラが、ローラ支持体に支持される複数の可動ローラの並び方向外方側に設けられるものであるから、上記のような段差が発生せず、物品を移載対象部との間で移載するにあたってスムーズに移載ができるものとなる。
That is, when the roller support is positioned on the outer side in the arrangement direction of the plurality of movable rollers supported by the roller support, that is, the portion that is the transfer direction end in the plan view of the article placement tool, Since the girder member that connects the upper member and the lower member cannot be provided in that portion, the strength of the article placement tool at the end portion in the transfer direction may be reduced. However, if it is configured such that there is no roller support at the end in the transfer direction in plan view of the article placement tool, there will be no movable roller at the end in the transfer direction, and it will be movable at the end in the transfer direction. Since the article placement surface located at a position lower than the upper end of the roller is in a continuous state, when the article is transferred to or from the transfer target part, the article is smoothly (with no rattling) ) There is a possibility that it cannot be transferred.
According to the third characteristic configuration, the height of the upper end is located above the article placement surface (preferably substantially the same as the height of the upper end of the movable roller when the roller support is located at the raised position). Since the position fixing roller whose vertical position is fixed is provided on the outer side in the arrangement direction of the plurality of movable rollers supported by the roller support, the above-described step does not occur and the article is transferred. When transferring to and from the target unit, transfer can be performed smoothly.

It is configured to be switchable to a raised position located above the placement surface Pf.
Note that switching between the raised position and the lowered position is performed when a push-up member Dp, which will be described later, is separated from the roller support Rs, and when the push-up member Dp abuts on the roller support Rs to push up the roller support Rs from below. This is realized by switching between states.
また、平面視においてローラ支持体Ｒｓに支持される複数の可動ローラＲの並び方向外方側、つまり、平面視においてローラ支持体Ｒｓの可動ローラＲ並び方向両端部と上部部材Ｐｊの可動ローラＲ並び方向の縁部との間には、上端が物品載置面Ｐｆよりも上方に位置する高さで上下位置が固定された位置固定ローラＲｋが設けられている。 Further, the plurality of movable rollers R supported by the roller support Rs in a plan view are arranged on the outer side in the arrangement direction, that is, both ends of the roller support Rs in the arrangement direction in the plan view and the movable roller R of the upper member Pj. Between the edges in the arrangement direction, there is provided a position fixing roller Rk whose upper and lower positions are fixed at a height at which the upper end is located above the article placement surface Pf.

金型Ｂは、パレットＰの物品載置面Ｐｆに載置支持された状態で、物品収納箇所に収納される。ここで、物品収納箇所とは、例えば平置き収納の場合には物品載置具収納用の床面であり、棚収納の場合にはその棚の収納部を指す。
パレットＰは、フォーク式の搬送装置Ｆとしてのスタッカークレーンやフォークリフトの爪部Ｆｔを前記フォーク挿通孔Ｐｆｈに挿入した状態で上記爪部Ｆｔにて上昇移動され、下部部材Ｐｓの下面が床面等から浮上した状態で搬送される。そして、図４（ａ）に示す如く、移載箇所としての載置具支持台Ｄに載置される。
つまり、フォーク式の搬送装置Ｆが、下部部材Ｐｓの下面が載置具支持台Ｄよりも高い位置となる状態にて、パレットＰを平面視で載置具支持台Ｄと重複する位置まで搬送し、その位置にてパレットＰを下降移動させて、パレットＰを載置具支持台Ｄに載置する。
Next, a procedure for transferring the mold B placed on the pallet P configured as described above to the transfer target part will be described.
The mold B is stored in the article storage location in a state where it is placed and supported on the article placement surface Pf of the pallet P. Here, the article storage location is, for example, a floor surface for storing the article placement tool in the case of flat storage, and the storage portion of the shelf in the case of shelf storage.
The pallet P is lifted and moved by the claw portion Ft in a state where the claw portion Ft of a stacker crane or forklift as the fork type conveying device F is inserted into the fork insertion hole Pfh, and the lower surface of the lower member Ps is the floor surface or the like It is transported in a state where it floats up. And as shown to Fig.4 (a), it mounts on the mounting tool support stand D as a transfer location.
That is, the fork-type transport device F transports the pallet P to a position overlapping the mounting tool support base D in plan view in a state where the lower surface of the lower member Ps is higher than the mounting tool support base D. Then, the pallet P is moved downward at that position, and the pallet P is placed on the placement tool support base D.
載置具支持台Ｄには、ローラ支持体Ｒｓに下方側から当接する押し上げ部材Ｄｐが昇降自在に設けられている。押し上げ部材Ｄｐは、下降位置においてはその上端部が載置具支持台Ｄにおける載置面よりも下方に位置し、上昇位置においてはその上端部が載置具支持台Ｄにおける載置面よりも上方に位置するように切換え自在に構成されている。 On the mounting tool support base D, a push-up member Dp that comes into contact with the roller support Rs from below is provided so as to freely move up and down. The push-up member Dp has an upper end located below the placement surface of the placement tool support base D in the lowered position, and an upper end portion of the push-up member Dp higher than the placement surface in the placement tool support base D at the raised position. It is configured to be switchable so as to be positioned above.
パレットＰが載置具支持台Ｄ上に載置されると、続いて、上記押し上げ部材Ｄｐを下降位置から上昇位置に切り換える。このとき、載置具支持台Ｄの載置面から上方に突出した押し上げ部材Ｄｐは、下部部材Ｐｓに設けられた開口部Ｐｓｈを通過して、上部部材Ｐｊと下部部材Ｐｓとの間に設けられるローラ支持体Ｒｓの下面に当接する。そして、引き続き押し上げ部材Ｄｐを上昇移動させると、押し上げ部材Ｄｐはローラ支持体Ｒｓを上方に押し上げることになる。 When the pallet P is placed on the placing tool support base D, the push-up member Dp is subsequently switched from the lowered position to the raised position. At this time, the push-up member Dp protruding upward from the placement surface of the placement tool support base D passes through the opening Psh provided in the lower member Ps and is provided between the upper member Pj and the lower member Ps. It contacts the lower surface of the roller support Rs. When the push-up member Dp is continuously moved upward, the push-up member Dp pushes up the roller support Rs upward.
すなわち、ローラ支持体Ｒｓに下方側から当接する押し上げ部材Ｄｐと上部部材Ｐｊとの相対距離を近接状態とすることにより、ローラ支持体Ｒｓが上昇位置に位置する移載作用状態とし、押し上げ部材Ｄｐと上部部材Ｐｊとの相対距離を離間状態とすることにより、ローラ支持体Ｒｓが下降位置に位置する退避状態とするように切換え自在に構成されている。
このようにして、押し上げ部材Ｄｐは、可動ローラＲの上端が物品載置面Ｐｆと下部部材Ｐｓとの間に位置する下降位置から可動ローラＲの上端が物品載置面Ｐｆよりも上方に位置する上昇位置に切り換えられる。
That is, by setting the relative distance between the push-up member Dp that contacts the roller support Rs from the lower side and the upper member Pj to be close to each other, the transfer support state in which the roller support Rs is located at the raised position is obtained, and the push-up member Dp By setting the relative distance between the upper member Pj and the upper member Pj to be separated from each other, the roller support Rs is configured to be switched so as to be in a retracted state located at the lowered position.
In this manner, the push-up member Dp is positioned such that the upper end of the movable roller R is located above the article placement surface Pf from the lowered position where the upper end of the movable roller R is located between the article placement surface Pf and the lower member Ps. Is switched to the ascending position.
以上のようにして、ローラ支持体Ｒｓが上昇位置に位置する移載作用状態とされると、金型Ｂの下面側にはローラ支持体Ｒｓに一体昇降自在に支持された可動ローラＲが当接し、かつ、摩擦抵抗の大きなパレットＰの物品載置面Ｐｆとは離間することになる。したがって、例えば作業者が手で金型を搬送方向に押すという簡易な作業によって、金型Ｂを容易にパレットＰ上から移載対象部に移載することができるものとなる。 As described above, when the roller support Rs is in the transfer operation state positioned at the raised position, the movable roller R supported by the roller support Rs so as to be movable up and down is applied to the lower surface side of the mold B. It contacts and is separated from the article placement surface Pf of the pallet P having a large frictional resistance. Therefore, for example, the mold B can be easily transferred from the pallet P to the transfer target portion by a simple operation in which the operator manually pushes the mold in the transport direction.
また、金型ＢをパレットＰ上から移載対象部に移載する場合に、パレットＰの移載方向端部には位置固定ローラＲｋが存在するため、パレットＰの移載方向端部においても金型Ｂは底部を載置支持されることとなり、安定した移載が行える。 Further, when the mold B is transferred from the pallet P to the transfer target portion, the position fixing roller Rk exists at the transfer direction end portion of the pallet P. Therefore, also at the transfer direction end portion of the pallet P. The mold B is placed and supported at the bottom, and stable transfer can be performed.
