特許文献１に記載されたような従来の間歇送り搬送装置では、駆動手段によって一定距離を往復移動せしめられる往復移動体に、この往復移動体上に設けられた上げ下げ自在な駆動部材（一般的には、搬送用走行体側の１つの被動部を前後から挟持する前後一対の上下揺動自在な駆動部材）を駆動する駆動手段、例えばシリンダーユニットが搭載されている。このような従来周知の構成では、上げ下げ自在な駆動部材を駆動する駆動手段が往復移動体上に設けられているため、単に往復移動体の全体重量が増大するだけでなく、当該駆動手段を制御する信号などを地上側と往復移動体との間でやり取りする必要があるため、設備コストが高くつくと共に、故障も生じ易くなる。 In the conventional intermittent feed transport device as described in Patent Document 1, a reciprocating moving body that is reciprocated by a driving means for a certain distance is provided with a vertically movable driving member (generally, a reciprocating moving body). Is equipped with a driving means (for example, a cylinder unit) for driving a pair of front-rear swingable drive members that sandwich one driven portion on the transport traveling body side from the front-rear direction. In such a conventionally known configuration, since the driving means for driving the drive member that can be raised and lowered is provided on the reciprocating moving body, not only the total weight of the reciprocating moving body is increased but also the driving means is controlled. Since it is necessary to exchange signals and the like between the ground side and the reciprocating mobile body, the equipment cost is high and failures are likely to occur.

本発明は、上記のような従来の問題点を解消することのできる間歇送り搬送装置を提案するものであって、本発明に係る間歇送り搬送装置は、後述する実施例との関係を理解し易くするために、当該実施例の説明において使用した参照符号を括弧付きで付して示すと、搬送用走行体(1)を一定間隔おきに間歇送りする間歇送り走行経路(20)には、この間歇送り走行経路(20)に沿って一定距離を往復移動する往復移動体(26)と、この往復移動体(26)を往復移動させる駆動手段(31)が設けられ、前記搬送用走行体(1)には被動部(13a)が設けられ、前記往復移動体(26)には、上げ下げ自在な駆動部材(35a)が設けられ、この駆動部材(35a)が上げ位置にあるとき、当該駆動部材(35a)と前記被動部(13a)とが係合して、前記搬送用走行体(1)を前記往復移動体(26)と一体に前進移動させるように構成された間歇送り搬送装置において、前記駆動部材(35a)にはカム従動ローラー(39)が軸支され、前記往復移動体(26)の往復移動経路(27)には、前記駆動部材(35a)が上げ位置にあるときの前記カム従動ローラー(39)を支持案内する固定ガイドレール(41)が架設され、この固定ガイドレール(41)の下側に、前記駆動部材(35a)が下げ位置にあるときの前記カム従動ローラー(39)の移動を許すローラー移動空間(42)が設けられ、前記固定ガイドレール(41)の始端部と終端部には、前記固定ガイドレール(41)に接続する上昇限位置と前記ローラー移動空間(42)に接続する下降限位置との間で昇降自在なローラー上げ下げ用昇降レール(43a)とその昇降駆動手段(44a)が配設された構成になっている。 The present invention proposes an intermittent feed transfer device capable of solving the above-mentioned conventional problems, and the intermittent feed transfer device according to the present invention understands the relationship with the examples described later. For the sake of simplicity, the reference symbols used in the description of the embodiment are shown in parentheses. The intermittent feed traveling route (20) for intermittently feeding the transport traveling body (1) at regular intervals is indicated. During this period, a reciprocating moving body (26) that reciprocates a fixed distance along the intermittent feed traveling path (20) and a driving means (31) that reciprocates the reciprocating moving body (26) are provided. The driven portion (13a) is provided in (1), and the reciprocating moving body (26) is provided with a drive member (35a) that can be raised and lowered. An intermittent feed transport device configured to engage the drive member (35a) and the driven portion (13a) to move the transport traveling body (1) forward integrally with the reciprocating moving body (26). When the cam driven roller (39) is pivotally supported by the driving member (35a) and the driving member (35a) is in the raised position in the reciprocating moving path (27) of the reciprocating moving body (26). A fixed guide rail (41) for supporting and guiding the cam driven roller (39) is erected, and the cam driven when the driving member (35a) is in a lowered position under the fixed guide rail (41). A roller moving space (42) is provided to allow the roller (39) to move, and at the start and end of the fixed guide rail (41), an ascending limit position connected to the fixed guide rail (41) and the roller are provided. An elevating rail (43a) for raising and lowering a roller and its elevating driving means (44a) that can be raised and lowered between the lowering limit position connected to the moving space (42) are arranged.

上記本発明の構成に係る搬送装置では、間歇送り動作の開始前は、固定ガイドレールの始端部側のローラー上げ下げ用昇降レールと終端部側のローラー上げ下げ用昇降レールは下降限位置にあり、往復移動経路の始端位置にある往復移動体の前記駆動部材はの下げ位置にあって、カム従動ローラーが前記始端部側の下降限位置にあるローラー上げ下げ用昇降レール上に位置している。この状況において、間歇送り走行経路に送り込まれた搬送用走行体を、間歇送り経路（往復移動体の往復移動経路）の始端側の所定位置で停止させたならば、前記始端部側のローラー上げ下げ用昇降レールを下降限位置から上昇限位置まで上昇させると、前記駆動部材のカム従動ローラーが、上昇するローラー上げ下げ用昇降レールによって押し上げられ、当該駆動部材が下げ位置から上げ位置に切り換わり、当該駆動部材が、停止待機している搬送用走行体の被動部と係合する。この後、往復移動体を始端位置から終端位置へ往行移動させることにより、上げ位置の駆動部材のカム従動ローラーが始端部側のローラー上げ下げ用昇降レールから前記固定ガイドレールに乗り移り、この固定ガイドレールに案内されて往復移動体と一体に前進移動するので、前記駆動部材は、搬送用走行体の被動部と係合する上げ位置を継続することになり、停止待機していた搬送用走行体が前記駆動部材に押されて間歇送り走行経路を、前記往復移動体と一体に前進移動することになる。前記終端部側のローラー上げ下げ用昇降レールは、前記始端部側のローラー上げ下げ用昇降レールを上昇位置に切り換えられるときに、同じように下降限位置から上昇限位置に切り換えられる。 In the transfer device according to the configuration of the present invention, before the start of the intermittent feed operation, the roller raising / lowering rail on the start end side and the roller raising / lowering rail on the end side of the fixed guide rail are in the lowering limit position and reciprocate. The driving member of the reciprocating moving body at the start position of the movement path is in the lowering position, and the cam driven roller is located on the roller raising / lowering rail at the lowering limit position on the starting end side. In this situation, if the transport traveling body sent to the intermittent feeding traveling path is stopped at a predetermined position on the starting end side of the intermittent feeding path (reciprocating moving path of the reciprocating moving body), the roller is raised and lowered on the starting end side. When the lifting rail is raised from the lowering limit position to the ascending limit position, the cam driven roller of the driving member is pushed up by the raising and lowering roller raising and lowering rail, and the driving member is switched from the lowering position to the raising position. The drive member engages with the driven portion of the transport traveling body that is on standby for stopping. After that, by moving the reciprocating moving body back and forth from the start position to the end position, the cam driven roller of the drive member in the raising position moves from the roller raising / lowering elevating rail on the starting end side to the fixed guide rail, and the fixed guide Since the drive member is guided by the rail and moves forward integrally with the reciprocating moving body, the driving member continues to be in the raised position where it engages with the driven portion of the transporting traveling body, and the transporting traveling body has been stopped and waiting. Is pushed by the driving member and moves forward in the intermittent feed traveling path integrally with the reciprocating moving body. The roller raising / lowering rail on the end portion side is similarly switched from the lowering limit position to the ascending limit position when the roller raising / lowering rail on the starting end side is switched to the ascending position.

上記動作により、搬送用走行体が積載している被搬送物が前記往復移動体の往行移動距離分だけ搬送されて停止するが、前記往復移動体が往復移動経路の終端所定位置で停止したとき、上げ位置の前記駆動部材のカム従動ローラーは、固定ガイドレールから前記終端部側の上昇限位置で待機しているローラー上げ下げ用昇降レールに乗り移っている。この後、当該終端部側のローラー上げ下げ用昇降レールを上昇限位置から下降限位置まで降下させることにより、カム従動ローラーを介して駆動部材が下げ位置に切り換えられ、搬送用走行体の被動部から外れるので、搬送用走行体を他の適当な駆動手段により間歇送り走行経路から退出移動させることが出来る。前記始端部側のローラー上げ下げ用昇降レールも、この時点で上昇限位置から下降限位置まで降下させておく。駆動部材が下げ位置に切り換えられた往復移動体は、往復移動経路の終端位置から始端位置へ復行移動させることが出来る。このときの下げ位置にある駆動部材は、そのカム従動ローラーが前記終端部側のローラー上げ下げ用昇降レールから逆方向に移動して離脱し、前記固定ガイドレールの下側の前記ローラー移動空間内を往復移動体と共に移動し、往復移動体が往復移動経路の始端位置に戻ったときには、上昇限位置から下降限位置に戻されている前記始端部側のローラー上げ下げ用昇降レール上に進入して停止する。 By the above operation, the object to be transported loaded by the transport traveling body is transported and stopped by the forward movement distance of the reciprocating moving body, but the reciprocating moving body is stopped at a predetermined position at the end of the reciprocating moving body. At this time, the cam driven roller of the driving member in the raising position is transferred from the fixed guide rail to the roller raising / lowering raising / lowering rail standing by at the raising limit position on the terminal side. After that, by lowering the roller raising / lowering rail for raising / lowering the roller on the terminal side from the raising limit position to the lowering limit position, the drive member is switched to the lowering position via the cam driven roller, and the driven portion of the traveling body for transportation is used. Since it comes off, the transport traveling body can be moved out of the intermittent feed traveling path by other suitable driving means. The elevating rail for raising and lowering the roller on the starting end side is also lowered from the ascending limit position to the lowering limit position at this point. The reciprocating body in which the driving member is switched to the lowered position can be moved back from the end position to the start position of the reciprocating movement path. The drive member in the lowered position at this time is separated from the cam driven roller by moving in the opposite direction from the roller raising / lowering / lowering rail on the terminal end side, and moves in the roller moving space under the fixed guide rail. It moves together with the reciprocating moving body, and when the reciprocating moving body returns to the starting position of the reciprocating moving path, it enters the roller raising / lowering rail on the starting end side, which has been returned from the ascending limit position to the lowering limit position, and stops. To do.

以上のように使用出来る本発明の間歇送り搬送装置によれば、往復移動体に取り付けられている、搬送用走行体の被動部に対して上下動を伴って係脱動作する駆動部材を下げ位置から上げ位置に、又は上げ位置から下げ位置に切り換えるための切換え用駆動手段は、往復移動経路の始端部と終端部の地上側に設けられたローラー上げ下げ用昇降レールと、駆動部材を上げ位置に保持する固定ガイドレールによって構成されているので、往復移動体上に前記駆動部材の位置切換え用駆動手段が設けられている従来の構成と比較して、往復移動する往復移動体上の前記駆動部材の位置切換え用駆動手段に対し地上側から電力や制御信号供給する必要がなくなり、設備コストが大幅に低減出来るだけでなく、往復移動体と地上側との間の電力や制御信号供給系に故障が生じる恐れが無くなり、メンテナンスも簡単容易に行える。 According to the intermittent feed transport device of the present invention that can be used as described above, the drive member attached to the reciprocating moving body that engages and disengages with the driven portion of the transport traveling body is lowered. The switching drive means for switching from the raising position to the raising position or from the raising position to the lowering position is the roller raising / lowering elevating rail provided on the ground side of the start end portion and the end portion of the reciprocating movement path, and the drive member in the raising position. Since it is composed of a fixed guide rail to be held, the driving member on the reciprocating moving body reciprocates as compared with a conventional configuration in which a driving means for switching the position of the driving member is provided on the reciprocating moving body. It is no longer necessary to supply power and control signals from the ground side to the position switching drive means, which not only significantly reduces equipment costs, but also causes a failure in the power and control signal supply system between the reciprocating body and the ground side. There is no risk of this occurring, and maintenance is easy and easy.

上記本発明を実施する場合、往復移動体(26)の前記駆動部材(35a)は、垂直に上下動作する駆動部材とすることも出来るが、この場合、搬送用走行体の前記被動部と係脱自在な係合部は、駆動部材の上端に設けられ、カム従動ローラーはその上端より低い高さで駆動部材の側部に軸支しなければならないので、前記駆動部材としては、上端の前記係合部を搬送用走行体の被動部から外れる高さまで降下させたとき、前記カム従動ローラーよりも下方に、往復移動体側に昇降自在に保持させる長さが必要になる。この結果、前記駆動部材全体の動作に必要な空間の高さが非常に大きくなるが、この不都合を解消するために、前記駆動部材(35a)を往復移動体(26)の移動方向に沿った棒状のものとし、その一端を前記往復移動体(26)に上下揺動自在に軸支すると共に、他端に、搬送用走行体(1)の前記被動部(13a)と係脱自在な係合部(36)を設け、下げ位置にある前記駆動部材(35a)は、往復移動体(26)によって支持されるように構成することが出来る。又、カム従動ローラー(39)は、棒状の駆動部材(35a)の中間位置に軸支することが出来、駆動部材が下げ位置にあるとき、上端の係合部と中間位置のカム従動ローラーとが倒伏姿勢の駆動部材と重なる状態になり、往復移動体側には、倒伏姿勢の駆動部材を支持出来るだけの空間高さがあれば良い。即ち、全体を非常にコンパクトに構成することが出来る。 When the present invention is carried out, the driving member (35a) of the reciprocating moving body (26) may be a driving member that moves up and down vertically, but in this case, it engages with the driven portion of the traveling body for transportation. The detachable engaging portion is provided at the upper end of the drive member, and the cam driven roller must be pivotally supported on the side portion of the drive member at a height lower than the upper end thereof. When the engaging portion is lowered to a height that disengages from the driven portion of the traveling body for transportation, a length that allows the engaging portion to be held up and down on the reciprocating moving body side below the cam driven roller is required. As a result, the height of the space required for the operation of the entire driving member becomes very large, but in order to eliminate this inconvenience, the driving member (35a) is moved along the moving direction of the reciprocating moving body (26). It has a rod shape, one end of which is vertically swingably supported by the reciprocating moving body (26), and the other end of which is freely engaged with the driven portion (13a) of the transport traveling body (1). The drive member (35a), which is provided with the joint portion (36) and is in the lowered position, can be configured to be supported by the reciprocating moving body (26). Further, the cam driven roller (39) can be pivotally supported at an intermediate position of the rod-shaped driving member (35a), and when the driving member is in the lowered position, the cam driven roller at the upper end and the intermediate position Is in a state of overlapping with the driving member in the lying posture, and it is sufficient that the space height on the reciprocating moving body side is sufficient to support the driving member in the lying posture. That is, the whole can be configured very compactly.

搬送用走行体(1)に必要な前記被動部(13a,14a)は、１つであっても良いが、走行方向に前後一対設けることが出来る。この場合、往復移動体(26)の前記駆動部材(35a,35b)は、当該往復移動体(26)の移動方向に前後一対設け、この前後一対の前記駆動部材(35a,35b)が上げ位置にあるとき、両駆動部材(35a,35b)の係合部(36)が前後一対の前記被動部(13a,14a)の内側に隣接するか又は両駆動部材(35a,35b)の係合部(36)が前後一対の前記被動部(13a,14a)の外側に隣接するように構成することが出来る。この構成によれば、搬送用走行体側の１つの被動部を挟持出来る開閉自在な挟持部を駆動部材に設ける構成と比較して、駆動部材関連の構造が簡単になり、安価に実施することが出来るだけでなく、搬送用走行体側に前後方向に離れて存在する２つの突起部をそのまま被動部として活用することが容易になる。尚、搬送用走行体(1)が、搬送台車本体(5)、この搬送台車本体(5)の前後両端部を支持する前側トロリー(3)と後端トロリー(4)、搬送台車本体(5)から前方に延出するロードバー(6)、及びこのロードバー(6)の前端に取り付けられた先頭トロリー(2)を備えた従来周知の構成のものである場合、前後一対の前記被動部(13a,14a)は、前記前側トロリー(3)と後端トロリー(4)のそれぞれ下側に突設することが出来る。 The driven portion (13a, 14a) required for the transport traveling body (1) may be one, but a pair of front and rear moving portions (13a, 14a) may be provided in the traveling direction. In this case, the driving members (35a, 35b) of the reciprocating moving body (26) are provided in pairs in the front-rear direction in the moving direction of the reciprocating moving body (26), and the pair of front-rear moving members (35a, 35b) are in the raised positions. When the engaging portion (36) of both driving members (35a, 35b) is adjacent to the inside of the pair of front and rear driven portions (13a, 14a), or the engaging portion of both driving members (35a, 35b) (36) can be configured to be adjacent to the outside of the pair of front and rear driven portions (13a, 14a). According to this configuration, the structure related to the drive member is simplified and can be implemented at low cost as compared with the configuration in which the drive member is provided with an openable and closable holding portion capable of sandwiching one driven portion on the side of the traveling body for transportation. Not only is it possible, but it becomes easy to utilize the two protrusions that are separated from each other in the front-rear direction on the side of the traveling body for transportation as the driven portion. The transport vehicle (1) includes a transport carriage body (5), a front trolley (3) and a rear end trolley (4) that support both front and rear ends of the transport carriage body (5), and a transport carriage body (5). In the case of a conventionally known configuration having a load bar (6) extending forward from) and a leading trolley (2) attached to the front end of the load bar (6), a pair of front and rear driven portions. (13a, 14a) can be projected below the front end trolley (3) and the rear end trolley (4), respectively.

更に、前記搬送用走行体(1)として、この搬送用走行体(1)の走行経路に沿って移動するプッシャー(15)に対し係脱自在な被動ドッグ(12)が前記先頭トロリー(2)に設けられ、前記前側トロリー(3)と後端トロリー(4)の下側には、後続の搬送用走行体(1)の先頭トロリー(2)の前記被動ドッグ(12)を前記プッシャー(15)から離脱させて当該後続の搬送用走行体(1)を停止させる操作用カム突起(13,14)が後方向きに突設されている搬送用走行体(1)を使用することが出来る場合、前記前側トロリー(3)は、その操作用カム突起(13)が前方向きとなるように前後逆向きに取り付け、搬送用走行体(1)の前後一対の前記被動部(13a,14a)は、後端トロリー(4)の後方向きの前記操作用カム突起(14)の前側の垂直背面(14a)と、前側トロリー(3)の前方向きの前記操作用カム突起(13)の後側の垂直背面(13a)とで構成することが出来る。従って、前後一対の駆動部材の係合部は、前側トロリーと後端トロリーの間に入り込んで、前側トロリーの前方向きの前記操作用カム突起の後側の垂直背面と、後端トロリーの後方向きの前記操作用カム突起の前側の垂直背面とに隣接することになる。 Further, as the transport traveling body (1), the driven dog (12) that can be engaged with and detached from the pusher (15) that moves along the traveling path of the transport traveling body (1) is the leading trolley (2). On the lower side of the front trolley (3) and the rear end trolley (4), the driven dog (12) of the head trolley (2) of the subsequent transport traveling body (1) is attached to the pusher (15). ), And the operation cam protrusions (13, 14) for stopping the subsequent transport vehicle (1) can be used. The front trolley (3) is attached in the opposite direction so that the operation cam protrusion (13) faces forward, and the pair of front and rear driven portions (13a, 14a) of the transport traveling body (1) are attached. , The front vertical back surface (14a) of the rear-facing operating cam protrusion (14) of the rear end trolley (4) and the rear side of the front-facing operating cam protrusion (13) of the front trolley (3). It can be configured with a vertical back surface (13a). Therefore, the engaging portions of the pair of front and rear drive members enter between the front end trolley and the rear end trolley, and face the front side of the front side trolley and the rear side of the operation cam projection facing the rear side and the rear end trolley toward the rear side. It will be adjacent to the vertical back surface on the front side of the operation cam protrusion.

尚、往復移動体(26)上の前後一対の駆動部材(35a,35b)は、往復移動体(26)の移動方向に等間隔おきに複数組設けて、等間隔おきに並ぶ複数の搬送用走行体(1)を同時に、搬送用走行体(1)間の間隔ごと間歇送りすることが出来る。この場合、各組の前後一対の駆動部材(35a,35b)のカム従動ローラー(39)を上げ下げするローラー上げ下げ用昇降レール(43a,43b)の内、往復移動体(26)の往復移動経路(27)の前後両端に位置するローラー上げ下げ用昇降レール(43a,43b)を除く全てのローラー上げ下げ用昇降レール(43a,43b)は、上昇限位置にあるとき、その前後両側の前記固定ガイドレール(41)間を接続するように構成すれば良い。 A pair of front and rear driving members (35a, 35b) on the reciprocating moving body (26) are provided in a plurality of sets at equal intervals in the moving direction of the reciprocating moving body (26), and are arranged at equal intervals for a plurality of transports. At the same time, the traveling body (1) can be intermittently fed at intervals between the traveling bodies (1) for transportation.

図１Ａ及び図２に示すように、本発明の実施例において使用される搬送用走行体１は、先頭トロリー２、前側トロリー３、後端トロリー４、前側トロリー３と後端トロリー４によって前後両端部が支持される搬送台車本体５、及び搬送台車本体５の前端部と前記先頭トロリー２とを連結するロードバー６から構成されている。３つのトロリー２〜４は、この搬送用走行体１の走行経路に沿って架設された断面コ字形の左右一対のガイドレール７に嵌合する左右一対前後二組の支持用車輪８と、前記左右一対のガイドレール７間に位置するようにそれぞれ垂直支軸によって軸支された前後一対の振れ止め用ローラー９を備えたもので、搬送台車本体５には、被搬送物Ｗを支持する支持台１０が支柱部材１１を介して支持されている。尚、従来周知のように、少なくとも水平カーブ経路部での搬送用走行体１の走行を可能にするために、各トロリー２〜４やロードバー６の前後両端部は、それぞれ垂直軸心の周りに相対回転自在に構成されている。 As shown in FIGS. 1A and 2, the transport traveling body 1 used in the embodiment of the present invention has front and rear ends by a front trolley 2, a front trolley 3, a rear end trolley 4, a front trolley 3 and a rear end trolley 4. It is composed of a transport carriage main body 5 on which the portion is supported, and a load bar 6 that connects the front end portion of the transport carriage main body 5 and the leading trolley 2. The three trolleys 2 to 4 are a pair of left and right supporting wheels 8 fitted to a pair of left and right guide rails 7 having a U-shaped cross section erected along the traveling path of the transport traveling body 1, and a pair of left and right supporting wheels 8 and the above. It is provided with a pair of front and rear steady rest rollers 9 that are pivotally supported by vertical support shafts so as to be located between the pair of left and right guide rails 7. The base 10 is supported via the support column member 11. As is well known in the past, in order to enable the transport traveling body 1 to travel at least on the horizontal curve path portion, the front and rear ends of the trolleys 2 to 4 and the load bar 6 are respectively around the vertical axis. It is configured to be relatively rotatable.

先頭トロリー２の下側には被動ドッグ１２が取り付けられ、前側トロリー３と後端トロリー４の下側には、後方向きに突出する操作用カム突起１３，１４が取り付けられている。被動ドッグ１２は、左右水平向きの支軸１２ａの周りに一定範囲内で上下シーソー運動可能に軸支されたもので、斜め後方下方に延出する後半部の下側に、プッシャー１５が嵌合する凹部１２ｂが形成され、前方に延出する前半部が***作部１２ｃとなっている。前記プッシャー１５は、ガイドレール７の下側中央位置を搬送用走行体１の走行経路に沿って移動する駆動用チエン１６に一定間隔おきに取り付けられたもので、停止している搬送台車に対して後方から接近移動してくるプッシャー１５が、被動ドッグ１２の斜め後方下方に延出する後半部の先端を押し上げて前記凹部１２ｂ内に嵌合し、この被動ドッグ１２を介して搬送用走行体１を前進駆動するものである。尚、駆動用チエン１６は、プッシャー１５の前後両側で当該駆動用チエン１６に取り付けられたトロリー１７を介して、断面Ｉ型の１本のガイドレール１８に移動可能に支持されている。 A driven dog 12 is attached to the lower side of the front trolley 2, and operation cam protrusions 13 and 14 projecting rearward are attached to the lower side of the front trolley 3 and the rear end trolley 4. The driven dog 12 is pivotally supported around a support shaft 12a in the horizontal left-right direction so that the seesaw can move up and down within a certain range, and the pusher 15 is fitted under the latter half extending diagonally backward and downward. The concave portion 12b is formed, and the front half portion extending forward is the operated portion 12c. The pusher 15 is attached to a drive chain 16 that moves at the lower center position of the guide rail 7 along the travel path of the transport traveling body 1 at regular intervals, and is attached to a stationary transport carriage. The pusher 15 approaching and moving from the rear pushes up the tip of the latter half extending diagonally backward and downward of the driven dog 12 to fit into the recess 12b, and the traveling body for transportation is fitted through the driven dog 12. 1 is driven forward. The drive chain 16 is movably supported by one guide rail 18 having a cross section I type via a trolley 17 attached to the drive chain 16 on both front and rear sides of the pusher 15.

後端トロリー４に取り付けられている操作用カム突起１４は、前記プッシャー１５によって前進駆動される搬送用走行体１が、停止している搬送用走行体１に後方から接近移動してくる場合に、図１Ａに示すように、その後続の搬送用走行体１の被動ドッグ１２の***作部１２ｃを下向きに押し下げて、当該被動ドッグ１２の後半部を上動させることにより、プッシャー１５に嵌合している凹部１２ｂをプッシャー１５から上方に離脱させて、後続の搬送用走行体１を自動停止させるものである。従って、搬送用走行体１を直列状にストレージするストレージ経路部の終端位置で、先頭の搬送用走行体１を、その被動ドッグ１２を従来周知のストッパーによってプッシャー１５から離脱させて所定位置に停止させると、後続の搬送用走行体１が、直前の停止搬送用走行体１の後端トロリー４の操作用カム突起１４によって順次自動停止せしめられ、直列状態でストレージさせることが出来る。このようにして直列状態でストレージされた搬送用走行体１は、先頭の搬送用走行体１を停止させていたストッパーを解除して、被動ドッグ１２を元の初期姿勢に復帰させることにより、接近移動してくるプッシャー１５によって先頭の搬送用走行体１を下手の方向に退出移動させ、これに伴って２番目の搬送用走行体１も、直前の搬送用走行体１の後端トロリー４の操作用カム突起１４が離れてゆくことにより、先頭トロリー２の被動ドッグ１２が元の初期姿勢に復帰し、後続のプッシャー１５によって前進走行を開始する。このようにして直列状態でストレージされていた搬送用走行体１を順次送り出すことが出来る。 The operation cam protrusion 14 attached to the rear end trolley 4 is used when the transport traveling body 1 driven forward by the pusher 15 approaches the stopped transport traveling body 1 from behind. As shown in FIG. 1A, the operated portion 12c of the driven dog 12 of the subsequent transport traveling body 1 is pushed downward and the latter half of the driven dog 12 is moved upward to fit into the pusher 15. The recess 12b is detached upward from the pusher 15 to automatically stop the subsequent traveling body 1 for transportation. Therefore, at the terminal position of the storage path portion for storing the transport traveling body 1 in series, the leading transport traveling body 1 is stopped at a predetermined position by separating the driven dog 12 from the pusher 15 by a conventionally known stopper. Then, the succeeding transport traveling body 1 is automatically stopped by the operation cam protrusion 14 of the rear end trolley 4 of the immediately preceding stop transporting traveling body 1, and can be stored in series. The transport traveling body 1 stored in the series state in this way approaches by releasing the stopper that stopped the leading transport traveling body 1 and returning the driven dog 12 to the original initial posture. The moving pusher 15 moves the leading transport traveling body 1 out and moves in the lower direction, and the second transport traveling body 1 also moves with respect to the rear end trolley 4 of the immediately preceding transport traveling body 1. As the operation cam protrusion 14 separates, the driven dog 12 of the leading trolley 2 returns to the original initial posture, and the subsequent pusher 15 starts forward traveling. In this way, the transport traveling bodies 1 stored in the series state can be sequentially sent out.

前側トロリー３に取り付けられている操作用カム突起１３は、図３に示すように、搬送用走行体１を斜めに並列する状態でストレージさせるストレージエリアにおいて機能するものである。即ち、このストレージエリアには、先頭トロリー２と前側トロリー３を走行させるためのガイドレール７Ａと、後端トロリー４を走行させるためのガイドレール７Ｂとが、前側トロリー３と後端トロリー４との間の距離よりも短い間隔で互いに平行に架設され、図示されていないが、プッシャー１５の走行経路となるガイドレール１８は、ガイドレール７Ａの下側中央位置に架設されている。而して、前記ストレージエリア内のガイドレール７Ａの始端部は、図１Ａに示すガイドレール７と接続され、ガイドレール７Ｂは、後端トロリー４をガイドレール７からガイドレール７Ｂへ分岐させる径路切換え装置を介して前記ガイドレール７に接続されている。 As shown in FIG. 3, the operation cam protrusion 13 attached to the front trolley 3 functions in a storage area for storing the transport traveling bodies 1 in a state of being diagonally parallel to each other. That is, in this storage area, a guide rail 7A for running the front trolley 2 and the front trolley 3 and a guide rail 7B for running the rear end trolley 4 are provided on the front trolley 3 and the rear end trolley 4. Although not shown, the guide rail 18 which is erected in parallel with each other at intervals shorter than the distance between them and serves as a traveling path of the pusher 15 is erected at the lower center position of the guide rail 7A. Thus, the start end of the guide rail 7A in the storage area is connected to the guide rail 7 shown in FIG. 1A, and the guide rail 7B is a path switching that branches the rear end trolley 4 from the guide rail 7 to the guide rail 7B. It is connected to the guide rail 7 via a device.

上記構成により、ガイドレール７上をプッシャー１５により前記ストレージエリアに向かって走行する搬送用走行体１は、その先頭トロリー２と前側トロリー３はガイドレール７Ａに導かれ、後端トロリー４はガイドレール７Ｂに送り込まれる。このようにしてストレージエリア内のガイドレール７Ａ，７Ｂに送り込まれた各搬送用走行体１の搬送台車本体５は、ガイドレール７Ａに沿って移動する前側トロリー３と、この前側トロリー３に引っ張られてガイドレール７Ｂに沿って移動する後端トロリー４とで支持されているため、ガイドレール７Ａ，７Ｂ間で斜めの姿勢で平行移動することになる。而して、先頭の搬送用走行体１は、先頭トロリー２が適当なストッパーによってプッシャー１５から切り離されて、ガイドレール７Ａの終端位置近傍の所定位置で停止せしめられるので、この先頭の搬送用走行体１に追従していた後続の搬送用走行体１は、ガイドレール７Ａを移動する先頭トロリー２の被動ドッグ１２が、停止している先行の搬送用走行体１の前側トロリー３の操作用カム突起１３によって操作されて、プッシャー１５から上方へ離脱し、先行停止搬送用走行体１の前側トロリー３の後ろに先頭トロリー２が追突する状態で自動停止することになる。後続の各搬送用走行体１は、同様に搬送台車本体５がガイドレール７Ａ，７Ｂ間に斜めに跨った姿勢で順次自動停止する。このようにして平行並列状態でストレージされた搬送用走行体１は、先頭の搬送用走行体１を停止させていたストッパーを解除して、被動ドッグ１２を元の初期姿勢に復帰させることにより、接近移動してくるプッシャー１５によって先頭の搬送用走行体１を下手の方向に退出移動させ、これに伴って２番目の搬送用走行体１も、直前の搬送用走行体１の前側トロリー３の操作用カム突起１３が離れてゆくことにより、先頭トロリー２の被動ドッグ１２が元の初期姿勢に復帰し、後続のプッシャー１５によって前進走行を開始する。このようにして平行並列状態でストレージされていた搬送用走行体１を順次送り出すことが出来る。 With the above configuration, the transport traveling body 1 traveling on the guide rail 7 toward the storage area by the pusher 15 is guided by the guide rail 7A at the front trolley 2 and the front trolley 3, and the rear end trolley 4 at the guide rail. It is sent to 7B. The transport trolley main body 5 of each transport traveling body 1 sent to the guide rails 7A and 7B in the storage area in this way is pulled by the front trolley 3 moving along the guide rail 7A and the front trolley 3. Since it is supported by the rear end trolley 4 that moves along the guide rail 7B, the guide rails 7A and 7B move in parallel in an oblique posture. Therefore, in the leading transport traveling body 1, the leading trolley 2 is separated from the pusher 15 by an appropriate stopper and stopped at a predetermined position near the end position of the guide rail 7A. In the subsequent transport traveling body 1 following the body 1, the driven dog 12 of the leading trolley 2 moving on the guide rail 7A is stopped, and the operation cam of the front side trolley 3 of the preceding transport traveling body 1 is stopped. Operated by the protrusion 13, it separates upward from the pusher 15 and automatically stops in a state where the leading trolley 2 collides with the front side trolley 3 of the preceding stop transport traveling body 1. Similarly, each of the subsequent traveling bodies 1 for transportation automatically stops in a posture in which the transport carriage main body 5 straddles the guide rails 7A and 7B at an angle. The transport traveling body 1 stored in the parallel-parallel state in this way releases the stopper that stopped the leading transport traveling body 1 and returns the driven dog 12 to the original initial posture. The pusher 15 that moves closer moves the leading transport traveling body 1 out and moves in the lower direction, and along with this, the second transport traveling body 1 also moves the front side trolley 3 of the immediately preceding transport traveling body 1. As the operation cam protrusion 13 separates, the driven dog 12 of the leading trolley 2 returns to the original initial posture, and the subsequent pusher 15 starts forward traveling. In this way, the transport traveling bodies 1 stored in the parallel-parallel state can be sequentially sent out.

以上に説明した搬送用走行体１の構成やストレージ方法は従来周知のものであるが、本発明の実施例は、上記のように使用されていた搬送用走行体１を利用するものである。即ち、水平カーブ経路部での搬送用走行体１の走行を可能にするために、図１Ａに示すように、各トロリー２〜４は、ロードバー６や搬送台車本体５のセンターフレームに上端が左右水平向きの支軸１９ａによって取り付けられた垂直支軸１９に、当該垂直支軸１９の周りに相対回転自在に取り付けられているものであるから、以下に説明する本発明の実施例では、図１Ｂに示すように、前側トロリー３を垂直支軸１９の周りに１８０度回転させて、操作用カム突起１３が前方向きに突出する前後逆向きの状態でガイドレール７に組み込まれる。従って図８に示すように、本発明の実施例に使用される搬送用走行体１では、前側トロリー３が後端トロリー４に対して前後対称向きとなり、図１Ａに示す従来の使用状態では、両トロリー３，４の操作用カム突起１３，１４の、同じ前方向きになっていた垂直背面１３ａ，１４ａが、図８に示すように、互いに対面する状態になっている。この実施例では、操作用カム突起１３，１４の垂直背面１３ａ，１４ａが、間歇送りのために搬送用走行体１側に必要な被動部となっている。勿論、このように改変された搬送用走行体１は、図３に示すように、前側トロリー３の操作用カム突起１３を機能させて、各搬送用走行体１を斜め平行状態にストレージさせることは出来ない。 Although the configuration and storage method of the transport traveling body 1 described above are well known in the past, the embodiment of the present invention utilizes the transport traveling body 1 used as described above. That is, in order to enable the transport traveling body 1 to travel on the horizontal curve path portion, as shown in FIG. 1A, each trolley 2 to 4 has an upper end on the center frame of the load bar 6 and the transport trolley main body 5. Since it is attached to the vertical support shaft 19 attached by the left and right horizontal support shafts 19a so as to be relatively rotatable around the vertical support shaft 19, in the embodiment of the present invention described below, the figure is shown. As shown in 1B, the front trolley 3 is rotated 180 degrees around the vertical support shaft 19 and incorporated into the guide rail 7 in a state in which the operating cam protrusion 13 projects forward and backward in the opposite direction. Therefore, as shown in FIG. 8, in the transport traveling body 1 used in the embodiment of the present invention, the front trolley 3 is oriented symmetrically with respect to the rear end trolley 4, and in the conventional use state shown in FIG. 1A, the front trolley 3 is oriented symmetrically with respect to the rear end trolley 4. As shown in FIG. 8, the vertical back surfaces 13a and 14a of the operation cam protrusions 13 and 14 of both trolleys 3 and 4 facing forward are in a state of facing each other. In this embodiment, the vertical back surfaces 13a and 14a of the operation cam protrusions 13 and 14 are driven portions required on the transport traveling body 1 side for intermittent feeding. Of course, in the transport traveling body 1 modified in this way, as shown in FIG. 3, the operation cam protrusion 13 of the front trolley 3 is made to function to store each transport traveling body 1 in an obliquely parallel state. I can't.

上記のように前側トロリー３を前後逆向きに付け替えた搬送用走行体１を使用する本発明の実施例を以下詳細に説明すると、図４に示すように、搬送用走行体１の走行経路途中に、当該搬送用走行体１の全長よりも長い間隔で、第一停止位置Ｐ１〜第五停止位置Ｐ５が等間隔おきに設定された直線状の間歇送り走行経路２０が設定されている。従って、搬送用走行体１を推進させるプッシャー１５を備えた駆動用チエン１６の移動経路には、間歇送り走行経路２０の第一停止位置Ｐ１の手前に設定された、間歇送り走行経路２０への送り込みのための準備停止位置Ｐ０から、間歇送り走行経路２０の最後の停止位置Ｐ５より下手側の合流点Ｐ６までの、平面視で間歇送り走行経路２０から側方に平行に離れたプッシャー迂回径路２１が設定されている。又、準備停止位置Ｐ０においてプッシャー１５から離れて停止した搬送用走行体１を間歇送り走行経路２０の第一停止位置Ｐ１まで送り込む搬送用走行体送り込み手段２２と、この搬送用走行体送り込み手段２２で送り込まれた搬送用走行体１を正確に第一停止位置Ｐ１で停止させるための位置決め手段２３、及び第五停止位置Ｐ５から搬送用走行体１を、前記プッシャー迂回径路２１の合流点Ｐ６より下手側迄送り出す搬送用走行体送り出し手段２４が併設されている。更に、間歇送り走行経路２０の各停止位置Ｐ１〜Ｐ５には、搬送用走行体１を所定位置にロックする搬送用走行体ロック手段２５Ａ〜２５Ｅが併設されている。 The embodiment of the present invention using the transport traveling body 1 in which the front trolley 3 is replaced in the reverse direction as described above will be described in detail below. As shown in FIG. 4, the traveling path of the transport traveling body 1 is in the middle. A linear intermittent feed traveling path 20 in which the first stop positions P1 to the fifth stop positions P5 are set at equal intervals is set at intervals longer than the total length of the transport traveling body 1. Therefore, the movement path of the drive chain 16 provided with the pusher 15 for propelling the transport traveling body 1 is set in front of the first stop position P1 of the intermittent feed traveling path 20 to the intermittent feed traveling path 20. Preparation for feeding From the stop position P0 to the confluence P6 on the lower side of the last stop position P5 of the intermittent feed travel path 20, a pusher detour route parallel to the side from the intermittent feed travel path 20 in a plan view. 21 is set. Further, a transport traveling body feeding means 22 for feeding the transport traveling body 1 stopped away from the pusher 15 at the preparation stop position P0 to the first stop position P1 of the intermittent feed traveling path 20, and the transport traveling body feeding means 22. The positioning means 23 for accurately stopping the transport traveling body 1 sent in the above at the first stop position P1, and the transport traveling body 1 from the fifth stop position P5 are moved from the confluence point P6 of the pusher detour path 21. A traveling body feeding means 24 for transporting the vehicle to the lower side is provided. Further, transport traveling body locking means 25A to 25E for locking the transport traveling body 1 to a predetermined position are provided at the respective stop positions P1 to P5 of the intermittent feed traveling path 20.

図５及び図６に示すように、間歇送り走行経路２０の真下には、この間歇送り走行経路２０と平行な棒状の往復移動体２６の往復移動経路２７が設けられている。この往復移動経路２７には、図９及び図１０Ａに示すように、往復移動体２６を挟むように左右一対の断面コ字形のガイドレール２８が架設され、往復移動体２６には、左右一対のガイドレール２８に嵌合する左右一対の支持用車輪２９と、左右一対のガイドレール２８間に位置する垂直軸周りに回転自在な上側及び下側の位置決め用ローラー３０とが、長さ方向適当間隔おきに設けられ、この往復移動体２６を、間歇送り走行経路２０における各停止位置Ｐ１〜Ｐ５間の間隔Ｄと等しい距離を往復移動させるための往復移動体駆動手段３１が併設されている。往復移動体２６は、前記間隔Ｄの４倍より長く且つ５倍より短い長さを有するもので、前記往復移動体駆動手段３１は、前記間隔Ｄより短くない長さで当該往復移動体２６の下側に平行に固着されたラックギア３２と、地上側の定位置に軸支されて前記ラックギア３２に咬合するモーター駆動のピニオンギヤ３３とで構成されている。尚、ピニオンギヤ３３が回転駆動されてラックギア３２を介して往復移動体２６が往復移動せしめられるとき、ピニオンギヤ３３から受ける上向きの力で往復移動体２６が、ガイドレール２８と支持用車輪２９との間の遊び代で浮き上がるのを防止するため、図９及び図１０Ａに示すように、ラックギア３２の長さ方向適当間隔おきの位置に、ガイドレール２８の下外側面に当接する左右一対の浮上り防止ローラー３２ａ，３２ｂが左右水平支軸の周りに回転自在に軸支されている。 As shown in FIGS. 5 and 6, a rod-shaped reciprocating moving body 26 parallel to the intermittent feeding traveling path 20 is provided with a reciprocating moving path 27 directly below the intermittent feeding traveling path 20. As shown in FIGS. 9 and 10A, a pair of left and right U-shaped guide rails 28 are erected on the reciprocating moving path 27 so as to sandwich the reciprocating moving body 26, and a pair of left and right guide rails 28 are erected on the reciprocating moving body 26. A pair of left and right support wheels 29 fitted to the guide rails 28 and upper and lower positioning rollers 30 rotatable around a vertical axis located between the pair of left and right guide rails 28 are appropriately spaced in the length direction. A reciprocating moving body driving means 31 is provided every other time to reciprocate the reciprocating moving body 26 by a distance equal to the interval D between the stop positions P1 to P5 in the intermittent feed traveling path 20. The reciprocating moving body 26 has a length longer than 4 times and shorter than 5 times the interval D, and the reciprocating moving body driving means 31 has a length not shorter than the interval D of the reciprocating moving body 26. It is composed of a rack gear 32 fixed in parallel to the lower side and a motor-driven pinion gear 33 that is pivotally supported at a fixed position on the ground side and meshes with the rack gear 32. When the pinion gear 33 is rotationally driven and the reciprocating moving body 26 is reciprocated via the rack gear 32, the reciprocating moving body 26 is moved between the guide rail 28 and the support wheel 29 by an upward force received from the pinion gear 33. As shown in FIGS. 9 and 10A, a pair of left and right lift prevention devices that come into contact with the lower and outer surfaces of the guide rail 28 at appropriate intervals in the length direction of the rack gear 32 are prevented from floating due to the play allowance. The rollers 32a and 32b are rotatably supported around the left and right horizontal support shafts.

往復移動体２６の上側には、この往復移動体２６の長さ方向に前記間隔Ｄと同一間隔で４つの連結手段３４Ａ〜３４Ｄが設けられている。各連結手段３４Ａ〜３４Ｄは、互いに同一構造のものであって、前後一対の駆動部材３５ａ，３５ｂから構成されている。図８及び図１０に示すように、両駆動部材３５ａ，３５ｂは、往復移動体２６の長さ方向と平行な棒状体から構成されたもので、その一端上側に左右両側に張り出す係合部３６が突設され、この係合部３６が互いに向き合う前後対称姿勢で両駆動部材３５ａ，３５ｂの他端部が往復移動体２６の上面に突設された軸受けに左右水平向きの支軸３７に上下揺動自在に軸支され、両駆動部材３５ａ，３５ｂの長さ方向の中間位置の同一側に水平方向に延出する軸状支持部材３８が片持ち状に取り付けられ、この各軸状支持部材３８の外端に左右水平支軸の周りに回転自在にカム従動ローラー３９が軸支されている。両駆動部材３５ａ，３５ｂは、重力で往復移動体２６の上に重なるように倒伏するが、この倒伏する駆動部材３５ａ，３５ｂを受け止めて各駆動部材３５ａ，３５ｂを下げ位置に保持する受け座４０が往復移動体２６の上に付設されている。 On the upper side of the reciprocating moving body 26, four connecting means 34A to 34D are provided at the same interval as the interval D in the length direction of the reciprocating moving body 26. Each of the connecting means 34A to 34D has the same structure as each other, and is composed of a pair of front and rear driving members 35a and 35b. As shown in FIGS. 8 and 10, both drive members 35a and 35b are composed of rod-shaped bodies parallel to the length direction of the reciprocating moving body 26, and engaging portions projecting to the upper side of one end on both the left and right sides. 36 is projected, and the other ends of both drive members 35a and 35b are projected on the upper surface of the reciprocating moving body 26 in a front-rear symmetrical posture in which the engaging portions 36 face each other.

As shown in FIGS. 13A and 13B, there are a holding arm 61 that can only open and close and swing at a fixed position, and a holding arm 61 on the upper side of the holding arm 61. With a reverse stop holding arm 62 that can reciprocate along the intermittent feed travel path 20 and allows the transport traveling body 1 of the plate-shaped projecting portion 48b of the transport carriage body 5 to pass in the traveling direction but prevents the passage in the opposite direction. It is composed of a cylinder unit 63 that reciprocates the reverse holding holding arm 62, and a plate-shaped protruding portion 48b of the transport carriage main body 5 is provided between the tip of the holding arm 61 and the tip of the reverse holding arm 62. Is sandwiched from the front and back, and the transport traveling body 1 is locked at a fixed position determined by the sandwiching arm 61. Explaining the specific structure, the movable body 65 is supported by a pair of left and right guide rails 64a and 64b erected in parallel with the intermittent feed traveling path 20 so as to be reciprocally movable, and the movable body 65 is supported on the base plate 65a supported by the movable body 65. The base of the check holding arm 62 is oscillated horizontally by a vertical support shaft 66, and the spring 67 that urges the check holding arm 62 in the direction of the check posture and the check holding arm 62 are reversed. A stopper 68 is provided to stop the vehicle in a stopped posture. The stopper 68 is fixed to the side surface of the base of the check valve holding arm 62, and the stopper 68 causes the check valve 68 to swing beyond the check posture by the urging force of the spring 67 on the side surface of the base plate 65a. To prevent it by contacting it.

前記挟持アーム６１は、前記ガイドレール６４ａ，６４ｂの一端部上に固定された基板６９の上に垂直支軸７０によって水平揺動自在に軸支され、この垂直支軸７０に遊嵌されたコイルスプリング７１によって、挟持アーム６１が、その先端が搬送台車本体５の板状突出部４８ｂの移動径路から下手側へ逃げる方向に回転するように付勢され、この挟持アーム６１を、搬送台車本体５の板状突出部４８ｂの移動径路から外側に外れた待機姿勢に保持するために、挟持アーム６１の基部から反対方向に延出するレバー部６１ａが連設されると共に、当該レバー部６１ａを受け止めて挟持アーム６１を前記待機姿勢に保持するストッパー７２が、前記基板６９上に突設されている。更に、この待機姿勢に保持されている挟持アーム６１をコイルスプリング７１の付勢力に抗して前記逆止挟持アーム６２のある側へ強制揺動させるために、前記可動体６５の先端に垂直支軸によって軸支されたローラー７３の基板６９から上方に突出する部分が、前記待機姿勢にある挟持アーム６１のレバー部６１ａに隣接している。尚、前記可動体６５には、ガイドレール６４ａ，６４ｂに支持される車輪やガイドレール６４ａ，６４ｂ間に遊嵌する垂直支軸周りに回転自在な振れ止め用ローラーなどが軸支されるが、前記ローラー７３は、上下一対前後二組の振れ止め用ローラーの内の前端上側のローラーを利用している。 The holding arm 61 is pivotally supported horizontally by a vertical support shaft 70 on a substrate 69 fixed on one end of the guide rails 64a and 64b, and is loosely fitted to the vertical support shaft 70. The spring 71 urges the holding arm 61 so that its tip rotates in a direction in which the tip thereof escapes from the moving path of the plate-shaped protruding portion 48b of the transport bogie body 5 to the lower side, and the holding arm 61 is urged to rotate in the direction of escaping to the lower side. In order to maintain the plate-shaped projecting portion 48b in a standby posture outside the moving path, a lever portion 61a extending in the opposite direction from the base of the holding arm 61 is continuously provided, and the lever portion 61a is received. A stopper 72 for holding the holding arm 61 in the standby position is projected on the substrate 69. Further, in order to forcibly swing the holding arm 61 held in this standby posture toward the side with the check holding holding arm 62 against the urging force of the coil spring 71, the holding arm 61 is vertically supported on the tip of the movable body 65. A portion of the roller 73 pivotally supported by the shaft that protrudes upward from the substrate 69 is adjacent to the lever portion 61a of the holding arm 61 in the standby posture. The movable body 65 is pivotally supported by wheels supported by the guide rails 64a and 64b, a rotatable steady rest roller around a vertical support shaft loosely fitted between the guide rails 64a and 64b, and the like. The roller 73 utilizes the roller on the upper front end of the pair of upper and lower pairs of front and rear steady rest rollers.

上記構成の搬送用走行体ロック手段２５Ａ〜２５Ｅによれば、図１３Ａに示すように、挟持アーム６１が待機姿勢にあり、そして逆止挟持アーム６２が後退限位置で且つ逆止姿勢にある状態で、搬送用走行体１が各停止位置Ｐ１〜Ｐ５の定位置まで送られると、その搬送用走行体１が定位置に達する直前で、搬送台車本体５の板状突出部４８ｂが逆止挟持アーム６２をスプリング６７の付勢力に抗して、図１３Ａに仮想線で示すように、挟持アーム６１側へ傾動させて当該逆止挟持アーム６２の位置を通過する。搬送用走行体１が各停止位置Ｐ１〜Ｐ５の定位置に達して停止すれば、シリンダーユニット６３を稼働させて可動体６５を前進移動させると、スプリング６７の付勢力とストッパー６８とで逆止姿勢に保持されている逆止挟持アーム６２が、台板６５ａを介して可動体６５と一体に前進移動すると同時に、可動体６５と一体に前進移動するローラー７３によって、レバー部６１ａを介して挟持アーム６１がコイルスプリング７１の付勢力に抗して逆止挟持アーム６２のある側へ強制的に回動することになる。この結果、定位置にある挟持アーム６１の先端と逆止挟持アーム６２の先端との間で搬送台車本体５の板状突出部４８ｂが挟持され、挟持アーム６１の先端位置で決まる各停止位置Ｐ１〜Ｐ５の定位置に搬送用走行体１がロックされることになる。 According to the transport traveling body locking means 25A to 25E having the above configuration, as shown in FIG. 13A, the holding arm 61 is in the standby position, and the check holding arm 62 is in the reverse limit position and the check position. Then, when the transporting traveling body 1 is sent to the fixed positions of the respective stop positions P1 to P5, the plate-shaped protruding portion 48b of the transporting carriage main body 5 is held by the check valve just before the transporting traveling body 1 reaches the fixed position. The arm 62 is tilted toward the holding arm 61 and passes through the position of the check holding arm 62, as shown by a virtual line in FIG. 13A, against the urging force of the spring 67. When the traveling body 1 for transportation reaches a fixed position of each of the stop positions P1 to P5 and stops, when the cylinder unit 63 is operated to move the movable body 65 forward, the urging force of the spring 67 and the stopper 68 check back. The check holding arm 62 held in the posture moves forward integrally with the movable body 65 via the base plate 65a, and at the same time, is held by the roller 73 that moves forward integrally with the movable body 65 via the lever portion 61a. The arm 61 is forced to rotate to the side with the check holding arm 62 against the urging force of the coil spring 71. As a result, the plate-shaped protrusion 48b of the transport carriage body 5 is sandwiched between the tip of the holding arm 61 at the fixed position and the tip of the check holding arm 62, and each stop position P1 determined by the tip position of the holding arm 61. The transport traveling body 1 is locked at a fixed position of ~ P5.

以下、全体の使用方法と作用について説明すると、搬送用走行体１は、駆動用チエン１６のプッシャー１５と先頭トロリー２の被動ドッグ１２との係合により、ガイドレール７によって定まる走行経路から間歇送り走行経路２０へと送られる。この搬送用走行体１が、図４に示す準備停止位置Ｐ０に到着すると、プッシャー１５を備えた駆動用チエン１６は、プッシャー迂回径路２１へ移動するので、プッシャー１５が先頭トロリー２の被動ドッグ１２から横方向に離脱し、当該搬送用走行体１は、準備停止位置Ｐ０で自動停止する。このときの搬送用走行体１の停止位置、即ち、準備停止位置Ｐ０は、図１２に示すように、搬送用走行体１の板状突出部４８ａが搬送用走行体送り込み手段２２の待機位置で停止している可動台５４上の逆止プッシャー５１をスプリング５６の付勢力に抗して前方に押し倒して通過した位置である。従って、逆止プッシャー５１はスプリング５６の付勢力で元の待機姿勢に復帰している。 Hereinafter, the overall usage and operation will be described. The transport traveling body 1 is intermittently fed from the traveling path determined by the guide rail 7 by engaging the pusher 15 of the driving chain 16 and the driven dog 12 of the leading trolley 2. It is sent to the traveling route 20. When the transport traveling body 1 arrives at the preparation stop position P0 shown in FIG. 4, the drive chain 16 provided with the pusher 15 moves to the pusher detour path 21, so that the pusher 15 is the driven dog 12 of the leading trolley 2. The transport traveling body 1 automatically stops at the preparation stop position P0. At this time, the stop position of the transport traveling body 1, that is, the preparation stop position P0 is, as shown in FIG. 12, the plate-shaped protruding portion 48a of the transport traveling body 1 is at the standby position of the transport traveling body feeding means 22. This is the position where the check pusher 51 on the stopped movable table 54 is pushed forward against the urging force of the spring 56 and passed. Therefore, the check pusher 51 returns to the original standby posture by the urging force of the spring 56.

搬送用走行体１が準備停止位置Ｐ０で停止したならば、搬送用走行体送り込み手段２２のシリンダーユニット５２を進出方向に稼働させ、可動台５４を所定距離だけ前進移動させると、当該可動台５４上の逆止プッシャー５１が板状突出部４８ａを介して搬送用走行体１を所定距離だけ後押し移動させて停止し、その後、シリンダーユニット５２を後退方向に稼働させて、搬送用走行体送り込み手段２２を元の待機位置に復帰させる。この搬送用走行体送り込み手段２２の搬送用走行体１の送り込み距離は、送り込む搬送用走行体１が間歇送り走行経路２０の第一停止位置Ｐ１に達する距離となっているが、慣性で第一停止位置Ｐ１を超えて停止することも考えられるので、搬送用走行体送り込み手段２２が搬送用走行体１の送り込みを開始する時点で、第一停止位置Ｐ１に併設されている位置決め手段２３を作動させる。即ち、図８〜図１０に示すように、シリンダーユニット６０を進出方向に稼働させてストッパー板５８を後退限位置から進出限位置まで進出させておく。この結果、送り込まれてくる搬送用走行体１の先頭トロリー２の被動ドッグ１２がストッパー板５８に乗り上げ、当該被動ドッグ１２が後ろ下がりの定常姿勢から押し上げられた後に当該ストッパー板５８の上手側側辺で制止される。この結果、搬送用走行体１が第一停止位置Ｐ１にほぼ一致する状態で停止する。 When the transport traveling body 1 is stopped at the preparation stop position P0, the cylinder unit 52 of the transport traveling body feeding means 22 is operated in the advancing direction, and the movable table 54 is moved forward by a predetermined distance to move the movable table 54 forward. The upper reverse stop pusher 51 pushes and moves the transport traveling body 1 by a predetermined distance via the plate-shaped projecting portion 48a to stop, and then operates the cylinder unit 52 in the backward direction to feed the transport traveling body 1. 22 is returned to the original standby position. The feed distance of the transport vehicle 1 of the transport vehicle feed means 22 is a distance at which the transport vehicle 1 to be fed reaches the first stop position P1 of the intermittent feed travel path 20, but it is first due to inertia. Since it is conceivable that the vehicle stops beyond the stop position P1, the positioning means 23 provided at the first stop position P1 is operated when the transport traveling body feeding means 22 starts feeding the transport traveling body 1. Let me. That is, as shown in FIGS. 8 to 10, the cylinder unit 60 is operated in the advancing direction to advance the stopper plate 58 from the retreating limit position to the advancing limit position. As a result, the driven dog 12 of the leading trolley 2 of the transport traveling body 1 that is sent rides on the stopper plate 58, and after the driven dog 12 is pushed up from the backward downward steady posture, the upper side side of the stopper plate 58 Stopped at the side. As a result, the transport traveling body 1 stops in a state that substantially coincides with the first stop position P1.

上記のようにして第一停止位置Ｐ１に送り込まれて停止した搬送用走行体１は、この第一停止位置Ｐ１に設けられている搬送用走行体ロック手段２５Ａに対応する位置にあって、当該搬送用走行体１の板状突出部４８ｂが、図１３Ａに示す待機状態での逆止挟持アーム６２をスプリング６７の付勢力に抗して前方に押し倒して通過し、退避姿勢にある挟持アーム６１の直前に達している。従って、当該搬送用走行体ロック手段２５Ａのシリンダーユニット６３を進出方向に稼働させて、先に説明したように、搬送用走行体１の板状突出部４８ｂを挟持アーム６１の先端と逆止挟持アーム６２の先端との間で挟持させ、搬送用走行体１を第一停止位置Ｐ１に正確にロックさせる。この搬送用走行体１の定位置でのロックが完了すれば、搬送用走行体送り込み手段２２のシリンダーユニット５２を後退方向に稼働させて、逆止プッシャー５１を元の待機位置に戻しておく。 The transport traveling body 1 that has been sent to the first stop position P1 and stopped as described above is at a position corresponding to the transport traveling body locking means 25A provided at the first stop position P1. The plate-shaped protruding portion 48b of the transport traveling body 1 pushes the check holding arm 62 in the standby state shown in FIG. 13A forward against the urging force of the spring 67 and passes through the holding arm 61 in the retracted posture. It has reached just before. Therefore, the cylinder unit 63 of the transport traveling body locking means 25A is operated in the advancing direction, and as described above, the plate-shaped protruding portion 48b of the transport traveling body 1 is held in reverse with the tip of the holding arm 61. It is sandwiched between the tip of the arm 62 and the transport traveling body 1 to be accurately locked to the first stop position P1. When the locking of the transport traveling body 1 at the fixed position is completed, the cylinder unit 52 of the transport traveling body feeding means 22 is operated in the backward direction to return the check pusher 51 to the original standby position.

一方、往復移動体２６は、図７の下段に示すように、後退限位置に戻されており、この往復移動体２６上の全ての連結手段３４Ａ〜３４Ｄは、前後一対の駆動部材３５ａ，３５ｂが往復移動体２６上に倒伏して受け座４０で支持されている状態であり、全ての停止位置Ｐ１〜Ｐ５に併設されている前後一対のローラー上げ下げ用昇降レール４３ａ，４３ｂは、固定ガイドレール４１の下側のローラー移動空間４２に接続する下降限位置にあるので、全ての連結手段３４Ａ〜３４Ｄの前後一対の駆動部材３５ａ，３５ｂが備えるカム従動ローラー３９は、下降限位置にあるローラー上げ下げ用昇降レール４３ａ，４３ｂ内に位置している。この状態で、各停止位置Ｐ１〜Ｐ５に併設されている前後一対のローラー上げ下げ用昇降レール４３ａ，４３ｂを、昇降駆動手段４４ａ，４４ｂのシリンダーユニット４７を進出方向に稼働させて、下降限位置から上昇限位置まで上昇させると、図８に示すように、全ての連結手段３４Ａ〜３４Ｄの下げ位置にある前後一対の駆動部材３５ａ，３５ｂが、ローラー上げ下げ用昇降レール４３ａ，４３ｂに嵌合しているカム従動ローラー３９を介して一定角度上向きに揺動して、所定の上げ位置に切り換わる。 On the other hand, the reciprocating moving body 26 has been returned to the retreat limit position as shown in the lower part of FIG. 7, and all the connecting means 34A to 34D on the reciprocating moving body 26 have a pair of front and rear driving members 35a and 35b. Is in a state of lying down on the reciprocating moving body 26 and being supported by the receiving seat 40, and the pair of front and rear roller raising and lowering rails 43a and 43b attached to all the stop positions P1 to P5 are fixed guide rails. Since it is in the lower limit position connected to the roller moving space 42 on the lower side of 41, the cam driven rollers 39 included in the pair of front and rear drive members 35a and 35b of all the connecting means 34A to 34D are in the lower limit position. It is located in the lifting rails 43a and 43b. In this state, the pair of front and rear roller raising / lowering rails 43a and 43b provided at the respective stop positions P1 to P5 are operated in the advancing direction by the cylinder units 47 of the raising / lowering drive means 44a and 44b, from the lowering limit position. When the vehicle is raised to the upper limit position, as shown in FIG. 8, the pair of front and rear drive members 35a and 35b at the lower positions of all the connecting means 34A to 34D are fitted into the roller raising and lowering raising and lowering rails 43a and 43b. It swings upward by a certain angle via the cam driven roller 39, and switches to a predetermined raised position.

上記作用により、図５の上段に示すように、第一停止位置Ｐ１にロックされている搬送用走行体１の前側トロリー３及び後端トロリー４の操作用カム突起１３，１４における、互いに対面状態にある垂直背面１３ａ，１４ａの内側に、上げ位置に切り換わった前後一対の駆動部材３５ａ，３５ｂの上端の係合部３６が隣接する状態になる。換言すれば、このような状況が確実に得られるように、往復移動体２６上の各連結手段３４Ａ〜３４Ｄの前後一対の駆動部材３５ａ，３５ｂの軸支位置、長さ、上げ位置での角度などが設定されている。勿論、往復移動体２６の後退限位置と前進限位置も正確に決まらなければならないが、当該往復移動体２６を往復移動させる往復移動体駆動手段３１が、往復移動体２６に一体のラックギア３２とモーター駆動のピニオンギヤ３３とから構成されているので、ピニオンギヤ３３を駆動するモーターの制御さえ設定通りに行えれば問題はない。 Due to the above action, as shown in the upper part of FIG. 5, the operating cam protrusions 13 and 14 of the front trolley 3 and the rear end trolley 4 of the transport traveling body 1 locked at the first stop position P1 face each other. The engaging portions 36 at the upper ends of the pair of front and rear drive members 35a and 35b that have been switched to the raised position are adjacent to the inside of the vertical back surfaces 13a and 14a. In other words, to ensure that such a situation can be obtained, the angles at the axial support positions, lengths, and raised positions of the pair of front and rear drive members 35a and 35b of the connecting means 34A to 34D on the reciprocating body 26. Etc. are set. Of course, the backward limit position and the forward limit position of the reciprocating moving body 26 must be accurately determined, but the reciprocating moving body driving means 31 for reciprocating the reciprocating moving body 26 is combined with the rack gear 32 integrated with the reciprocating moving body 26. Since it is composed of a motor-driven pinion gear 33, there is no problem as long as the motor that drives the pinion gear 33 can be controlled as set.

上記のようにローラー上げ下げ用昇降レール４３ａ，４３ｂを上昇限位置に切り換えたならば、第一停止位置Ｐ１に併設されている位置決め手段２３のシリンダーユニット６０を後退方向に稼働させて、ストッパー板５８を待機位置である後退限位置に戻して、ストッパー板５８を搬送用走行体１の先頭トロリー２の被動ドッグ１２から離脱させると共に、各停止位置Ｐ１〜Ｐ５の搬送用走行体ロック手段２５Ａ〜２５Ｅのシリンダーユニット６３を後退方向に稼働させ、挟持アーム６１をコイルスプリング７１の付勢力で搬送用走行体１の板状突出部４８ｂの前進経路から退出させると共に、逆止挟持アーム６２を元の待機位置まで後退復帰させる。 When the roller raising / lowering rails 43a and 43b are switched to the ascending limit positions as described above, the cylinder unit 60 of the positioning means 23 provided at the first stop position P1 is operated in the retracting direction to operate the stopper plate 58. To return the stopper plate 58 to the retreat limit position, which is the standby position, to separate the stopper plate 58 from the driven dog 12 of the leading trolley 2 of the transport traveling body 1, and to lock the transport traveling bodies 25A to 25E at the respective stop positions P1 to P5. The cylinder unit 63 of the above is operated in the backward direction, the holding arm 61 is retracted from the forward path of the plate-shaped protruding portion 48b of the transport traveling body 1 by the urging force of the coil spring 71, and the check holding holding arm 62 is in the original standby state. Retreat to the position.

次に往復移動体駆動手段３１のピニオンギヤ３３を正方向に回転駆動して、往復移動体２６を後退限位置から進出限位置まで前進させて停止させる。このとき第一停止位置Ｐ１で停止していた搬送用走行体１は、往復移動体２６上の連結手段３４Ａの前後一対の駆動部材３５ａ，３５ｂにより当該往復移動体２６に対して前後方向に相対移動出来ない状態に連結されているので、往復移動体２６と一体に間歇送り走行経路２０を一定距離だけ前進移動し、図５の下段に示すように、次の第二停止位置Ｐ２で停止する。このときの往復移動体２６の前進移動により、各連結手段３４Ａ〜３４Ｄの上げ位置に切り換えられていた前後一対の駆動部材３５ａ，３５ｂの各カム従動ローラー３９は、上昇限位置にある各ローラー上げ下げ用昇降レール４３ａ，４３ｂ内から下手側に隣接する固定ガイドレール４１内に移動し、後ろ側の駆動部材３５ｂのカム従動ローラー３９は、前側の駆動部材３５ａのカム従動ローラー３９を支持していたローラー上げ下げ用昇降レール４３ａ内を経由してその下手側の固定ガイドレール４１内に移動する。このようにして各連結手段３４Ａ〜３４Ｄの前後一対の駆動部材３５ａ，３５ｂは、搬送用走行体１と連結状態になる上げ位置を保ったままそれぞれ下手側の停止位置Ｐ２〜Ｐ５に移動することになる。 Next, the pinion gear 33 of the reciprocating moving body driving means 31 is rotationally driven in the forward direction to advance the reciprocating moving body 26 from the backward limit position to the advance limit position and stop it. At this time, the transport traveling body 1 stopped at the first stop position P1 is relative to the reciprocating moving body 26 in the front-rear direction by a pair of front-rear driving members 35a and 35b of the connecting means 34A on the reciprocating moving body 26. Since it is connected in a non-movable state, it moves forward by a certain distance along the intermittent feed traveling path 20 integrally with the reciprocating moving body 26, and stops at the next second stop position P2 as shown in the lower part of FIG. .. Due to the forward movement of the reciprocating moving body 26 at this time, the cam driven rollers 39 of the pair of front and rear drive members 35a and 35b, which have been switched to the raising positions of the connecting means 34A to 34D, raise and lower each roller in the raising limit position. The cam driven roller 39 of the rear drive member 35b moved from the inside of the lift rails 43a and 43b to the fixed guide rail 41 adjacent to the lower side, and supported the cam driven roller 39 of the front drive member 35a. It moves into the fixed guide rail 41 on the lower side of the roller raising / lowering rail 43a via the roller raising / lowering rail 43a. In this way, the pair of front and rear drive members 35a and 35b of the connecting means 34A to 34D move to the lower stop positions P2 to P5 while maintaining the raised positions in which they are connected to the transport traveling body 1. become.

以上のようにして第一停止位置Ｐ１から第二停止位置Ｐ２に移された搬送用走行体１は、この第二停止位置Ｐ２に併設されている搬送用走行体ロック手段２５Ｂによって、第一停止位置Ｐ１での搬送用走行体ロック手段２５Ａによるロック作用と同様のロック作用により、定位置（第二停止位置Ｐ２）にロックされる。この後、図７の上段に示すように、各停止位置Ｐ１〜Ｐ５のローラー上げ下げ用昇降レール４３ａ，４３ｂをその昇降駆動手段４４ａ，４４ｂにより上昇限位置から下降限位置に降下させ、第二停止位置Ｐ２のローラー上げ下げ用昇降レール４３ａ，４３ｂによって上げ位置に保持されていた往復移動体２６上の前後一対の駆動部材３５ａ，３５ｂを、往復移動体２６上の受け座４０で支持される下げ位置に切り換える。この結果、当該前後一対の駆動部材３５ａ，３５ｂの係合部３６が、第二停止位置Ｐ２に停止している搬送用走行体１の前側トロリー３と後端トロリー４の操作用カム突起１３，１４から下方に離脱させ、当該搬送用走行体１と往復移動体２６との連結を解除する。 The transport traveling body 1 moved from the first stop position P1 to the second stop position P2 as described above is first stopped by the transport traveling body locking means 25B provided at the second stop position P2. It is locked to a fixed position (second stop position P2) by a locking action similar to the locking action by the transport traveling body locking means 25A at the position P1. After that, as shown in the upper part of FIG. 7, the roller raising / lowering rails 43a and 43b of the stop positions P1 to P5 are lowered from the ascending limit position to the lowering limit position by the raising / lowering driving means 44a and 44b, and the second stop is performed. The lowering position in which the pair of front and rear drive members 35a and 35b on the reciprocating moving body 26 held in the raising position by the roller raising and lowering raising and lowering rails 43a and 43b at the position P2 are supported by the receiving seat 40 on the reciprocating moving body 26. Switch to. As a result, the engaging portions 36 of the pair of front and rear drive members 35a and 35b are the operation cam protrusions 13 of the front trolley 3 and the rear end trolley 4 of the transport traveling body 1 stopped at the second stop position P2. It is separated downward from 14, and the connection between the transport traveling body 1 and the reciprocating moving body 26 is released.

次に、往復移動体駆動手段３１のピニオンギヤ３３を逆方向に回転駆動して、前進限位置にあった往復移動体２６を、図７の下段に示すように、後退限位置まで後退移動させる。このとき、下げ位置にある状態で往復移動体２６上に支持されている前後一対の駆動部材３５ａ，３５ｂのカム従動ローラー３９は、下降限位置にある前後一対のローラー上げ下げ用昇降レール４３ａ，４３ｂから上手側に接続しているローラー移動空間４２内に退出し、このローラー移動空間４２内を後退移動する。カム従動ローラー３９の後退移動方向側に別の下降限位置にあるローラー上げ下げ用昇降レール４３ａ，４３ｂがあるときは、そのローラー上げ下げ用昇降レール４３ａ，４３ｂ内を経由して更に上手側のローラー移動空間４２内へ移動する。 Next, the pinion gear 33 of the reciprocating moving body driving means 31 is rotationally driven in the opposite direction to move the reciprocating moving body 26, which was in the forward limiting position, backward to the backward limiting position as shown in the lower part of FIG. At this time, the cam driven rollers 39 of the pair of front and rear drive members 35a and 35b supported on the reciprocating moving body 26 in the lowered position are the front and rear pair of front and rear roller raising and lowering rails 43a and 43b in the lowering limit position. It exits into the roller moving space 42 connected to the upper side, and moves backward in the roller moving space 42. If there are roller raising / lowering elevating rails 43a, 43b at different lowering limit positions on the cam driven roller 39 in the backward moving direction side, the roller moving on the better side via the roller raising / lowering elevating rails 43a, 43b. Move into space 42.

以上の作用により、準備停止位置Ｐ０で停止している搬送用走行体１を、搬送用走行体送り込み手段２２により第一停止位置Ｐ１に送り込み、この第一停止位置Ｐ１で一旦停止した搬送用走行体１を、往復移動体２６上の連結手段３４Ａの前後一対の駆動部材３５ａ，３５ｂによって第二停止位置Ｐ２まで送り込んだことになるが、このとき第一停止位置Ｐ１には、後退限位置にある往復移動体２６の連結手段３４Ａの前後一対の駆動部材３５ａ，３５ｂが下げ位置で待機しており、そのカム従動ローラー３９は、第一停止位置Ｐ１で下降限位置にあるローラー上げ下げ用昇降レール４３ａ，４３ｂ内に嵌合しているので、準備停止位置Ｐ０から搬送用走行体１を受け入れる最初の態勢に戻ったことになる。従ってこれ以降は、各停止位置Ｐ１〜Ｐ５の搬送用走行体ロック手段２５Ａ〜２５Ｅの全てとローラー上げ下げ用昇降レール４３ａ，４３ｂの全てを、往復移動体２６の往復移動に同期させて、先に説明したように動作させることにより、準備停止位置Ｐ０から第一停止位置Ｐ１に送り込まれた搬送用走行体１を、第一停止位置Ｐ１から第五停止位置Ｐ５まで順番に停止させながら移送させることが出来るのである。 By the above action, the transport traveling body 1 stopped at the preparation stop position P0 is fed to the first stop position P1 by the transport traveling body feeding means 22, and the transport traveling body temporarily stopped at the first stop position P1. The body 1 is sent to the second stop position P2 by the pair of front and rear drive members 35a and 35b of the connecting means 34A on the reciprocating moving body 26, but at this time, the first stop position P1 is set to the retreat limit position. A pair of front and rear drive members 35a and 35b of a connecting means 34A of a reciprocating moving body 26 are on standby at a lowering position, and the cam driven roller 39 is an elevating rail for raising and lowering the roller which is in the lowering limit position at the first stop position P1. Since it is fitted in the 43a and 43b, it means that it has returned to the initial posture of accepting the transport traveling body 1 from the preparation stop position P0. Therefore, after that, all of the transport traveling body locking means 25A to 25E and all of the roller raising and lowering elevating rails 43a and 43b at the respective stop positions P1 to P5 are synchronized with the reciprocating movement of the reciprocating moving body 26, and first. By operating as described, the transport traveling body 1 sent from the preparation stop position P0 to the first stop position P1 is transferred while being stopped in order from the first stop position P1 to the fifth stop position P5. Can be done.

第五停止位置Ｐ５に送り込まれた搬送用走行体１は、搬送用走行体送り出し手段２４を、搬送用走行体送り込み手段２２と同じように動作させることにより、プッシャー迂回径路２１の合流点Ｐ６より下手側に先頭トロリー２が入り込む位置まで送り出すことが出来る。このようにしてプッシャー迂回径路２１の合流点Ｐ６より下手側に送り出された搬送用走行体１は、前記合流点Ｐ６から搬送用走行体１の走行経路下に入り込んで当該搬送用走行体１の走行経路に沿って移動することになる駆動用チエン１６のプッシャー１５が、先頭トロリー２の被動ドッグ１２の後方から当該被動ドッグ１２の凹部１２ｂ内に自動係合して、当該搬送用走行体１を推進させことになる。 The transport traveling body 1 fed to the fifth stop position P5 operates the transport traveling body feeding means 24 in the same manner as the transport traveling body feeding means 22 from the confluence point P6 of the pusher detour path 21. It can be sent out to the position where the leading trolley 2 enters on the lower side. In this way, the transport traveling body 1 sent out to the lower side from the confluence P6 of the pusher detour path 21 enters under the traveling path of the transport traveling body 1 from the confluence P6 and is the transport traveling body 1. The pusher 15 of the driving chain 16 that moves along the traveling path automatically engages with the recess 12b of the driven dog 12 from behind the driven dog 12 of the leading trolley 2, and the transport traveling body 1 Will be promoted.

尚、本発明の好適な実施例を示す図面に基いて説明したが、搬送用走行体１に必要な被動部（操作用カム突起１３，１４の垂直背面１３ａ，１４ａ）や往復移動体２６側の駆動部材３５ａ，３５ｂの構造や数は、上記実施例に示したものに限定されない。例えば前後一対ではなく、１つの垂直に昇降する駆動部材を往復移動体２６に設けることも可能であるし、このような垂直に昇降する駆動部材であれば、搬送用走行体１側の被動部は、駆動部材の上端が嵌まり込む凹部とすることも出来る。又、搬送用走行体１自体の構造も、上記実施例に示したものに限定されない。往復移動体２６の後退移動時にカム従動ローラー３９がローラー移動空間４２を移動するが、ローラー移動空間４２は、固定ガイドレール４１と同様の固定ガイドレールを架設して構成することも出来る。この場合は、往復移動体２６上に設けた受け座４０が不要になる。 Although described with reference to the drawings showing a preferred embodiment of the present invention, the driven portion (vertical back surfaces 13a and 14a of the operation cam protrusions 13 and 14) and the reciprocating moving body 26 side required for the transport traveling body 1 have been described. The structure and number of the driving members 35a and 35b are not limited to those shown in the above embodiment. For example, it is possible to provide one vertically elevating drive member on the reciprocating moving body 26 instead of a pair of front and rear moving members. Can also be a recess into which the upper end of the drive member fits. Further, the structure of the transport traveling body 1 itself is not limited to that shown in the above embodiment. The cam driven roller 39 moves in the roller moving space 42 when the reciprocating moving body 26 moves backward, and the roller moving space 42 can be configured by erection of a fixed guide rail similar to the fixed guide rail 41. In this case, the receiving seat 40 provided on the reciprocating moving body 26 becomes unnecessary.

本発明の間歇送り搬送装置は、直線搬送経路上で等間隔おきに設定した各停止位置で被搬送物を一旦停止させて、被搬送物に対する作業を行うようなシステムに活用出来る。 The intermittent feed transport device of the present invention can be utilized in a system in which the transported object is temporarily stopped at each stop position set at equal intervals on the linear transport path to perform work on the transported object.
