岐情報に従って分岐方向を決定するという制御方式であ
った。Conventionally, the method used to control a branching direction changing device in a transfer system such as a conveyor is that before the transfer starts, information indicating the branching direction at each branching point is given to the conveying body in advance, and the control system is used to control the branching direction at each branching point. This control method determined the branching direction according to the branching information for each branching point.
しかしながら、上記従来の制御方式は分岐判断が繁雑で
あるばかりですく、移送システムのレイアウトを変更し

搬処理をしなければならない不能があった。However, in the conventional control method described above, branching decisions are complicated, and when the layout of the transfer system is changed, the control device must be reconfigured, and erroneous feeds may occur. At the time, there was an inability to carry out transportation processing based on the input.
誤送を自動的に処理しようとしても非常に複雑なソフト
を必要とするので、実際には不能である。Even if an attempt was made to automatically handle erroneous deliveries, it would be practically impossible as it would require extremely complex software.
本発明の目的は上記従来の欠点を除去した分岐装置を提

た周知の分岐装置を用いる。For the transfer device T, a reciprocating conveyor such as a reversible conveyor or a self-propelled carrier is used, and as a branching direction changing device in the branching device, if the transfer device T is a chain conveyor, for example, it is equipped with a reversible live roller conveyor that moves up and down between chains. If the transfer device T is a self-propelled carrier, a known branching device suitable for the transfer device T is used, such as a turntable.

しかし載荷点ないし作業開始点を含む移送路から順次番
地を付する方が餌料であろう。However, it would be better to assign addresses sequentially from the transfer path including the loading point or work start point.

例えば第１図においてａ点からｅ点に移送する場合の上
記の分岐路選択動作を具体的に説明すると、いま矢印方
向ｌこ移送する各移送路の番地を順次０〜１５とすれば
移送物の行先番地は９である。For example, in the case of transferring from point a to point e in FIG. The destination address is 9.
ａ点を出発した移送物が分岐点１に達すると、点１にお
ける分岐路の往行移送路の番地は１，３゜１５である。When the transferred object departing from point a reaches branch point 1, the address of the outgoing transfer path of the branch path at point 1 is 1.3°15.
しかるとき行先番地９との間には３ ＜９＜１５の関係
があるから番地３の分岐路が選択され、移送物は分岐点
ｍに移送される。At this time, since there is a relationship of 3 < 9 < 15 with destination address 9, the branch road with address 3 is selected and the object is transferred to branch point m.
分岐点ｍにおいては分岐路の往行移送路の番地が４゜６
．８．１４であるから８＜９＜１４の関係があり番地８
の分岐路が選択されて移送物は分岐点ｎに移送される。At branch point m, the address of the outgoing transfer road of the branch road is 4°6
．． Since it is 8.14, there is a relationship of 8<9<14 and the address is 8.
branch path is selected and the object is transferred to branch point n.
分岐点ｎにおいては分岐路の往行移送路の番地が９，１
１，１３であるから番地９の分岐路が選択されて移送物
はｅ点に到達する。At branch point n, the address of the outgoing transfer route of the branch road is 9,1.
1 and 13, the branch road with address 9 is selected and the transported object reaches point e.
ｅ点；こ達すれば端末装置が行先番地を読み出して番地
９の分岐路または移送物を停止せしめる。Point e: When this point is reached, the terminal device reads the destination address and stops the branch at address 9 or the transported object.

検出し、移送物を元の分岐点に逆送する。If the transferred object arrives at another work point due to a misjudgment of branching, the terminal device at that working point detects that the destination address is different and sends the transferred object back to the original branch point.
そして元の分岐点において再び分岐判断が行われること
になる。Then, a branch decision is made again at the original branch point.
上記実施例においては、各分岐点ごとに分岐判断装置４
