Two support members 24 and 24 are erected on both the left and right sides of the support member. Between the upper end of each support member 18 and the upper part of each rotary member 12, a support shaft 19 oriented in the front-rear direction is provided as a bearing 20. The support shaft 19 is mounted with a plate-like gripping member 21 extending inward. In addition, an upward cylinder 22 is pivotally provided at the tip of each rotating member 12 so as to be tiltable in the left-right direction, and one end of a support shaft 19 is connected to the upper end of the piston rod of each cylinder 22 via a link mechanism 23. The pair of gripping members 21 and 21 are connected to each other to rotate up and down by the expansion and contraction operation of the pair of cylinders 22 and 22 so as to open and close the upper space of the rail 15.
また、図６に示すように、枠状の支柱部材１８の内側にはクランプ機構１４の一部を構成する楔機構２６が１対の渡し部材２５・２５を介して装着してあり、楔機構２６は、図５に示すように、楔２７をピントンロットに嵌着したシリンダ２８と、シリンダ２８に装着された圧縮空気の切換えバルブ２９とで構成してある。また、一対の回動部材１２・１２の下部には、図７に示すように、クランプ機構１４の一部を構成する受け止め機構３０が装着してある。そして、シリンダ２８の伸長作動により楔２７が金枠１の側面に形成された穴に進入するとともに、走行台車７を介在させて金枠１を止め機構３０に押し付けて金枠１を固定することができるようになっている。 Further, as shown in FIG. 6, a wedge mechanism 26 constituting a part of the clamp mechanism 14 is mounted on the inner side of the frame-shaped support member 18 via a pair of transfer members 25 and 25.

Then, the wedge 27 enters the hole formed in the side surface of the metal frame 1 by the extension operation of the cylinder 28, and the metal frame 1 is fixed by pressing the metal frame 1 against the stop mechanism 30 with the traveling carriage 7 interposed therebetween. Can be done.
また、図１に示すように、第１移送手段２における鋳型移し替え装置４の左右両側位置には、クランプ機構１４と同一の構造および作用効果を有する２個のクランプ機構３３・３４がそれぞれ配設してある。 In addition, as shown in FIG. 1, two clamp mechanisms 33 and 34 having the same structure and effect as the clamp mechanism 14 are respectively arranged on the left and right side positions of the mold transfer device 4 in the first transfer means 2. It is set up.
このように構成したものは、図８に示すように、把持機構１３の一対のシリンダ２２・２２を収縮作動して一対の把持部材２１・２１を開いた状態の下に、注湯済み重畳状態の上下鋳型Ｍの下鋳型を内蔵した複数の金枠１・１を、第１移送手段２の複数の走行台車７・７によって１個の金枠１のピッチで間歇的に矢印方向へ移送して（図１参照）、１個の上下鋳型Ｍおよび金枠１を鋳型移し替え装置４の一対の回動部材１２・１２のレール１５上に搬入し、続いて、第１移送手段２上における鋳型移し替え装置４の左右両側の金枠１・１を２個のクランプ機構３３・３４によりそれぞれクランプして固定した後（図１参照）、一対の回動部材１２・１２上の金枠１をクランプ機構１４によりクランプする（図１参照）。 As shown in FIG. 8, the structure constructed in this way is in a superposed state in which a pair of cylinders 22, 22 of the gripping mechanism 13 is contracted and the pair of gripping members 21, 21 is opened, and the poured hot water is superposed. A plurality of metal frames 1, 1 incorporating a lower mold of the upper and lower molds M are intermittently transferred in the direction of the arrow at a pitch of one metal frame 1 by a plurality of traveling carriages 7, 7 of the first transfer means 2. (See FIG. 1), one upper and lower mold M and the metal frame 1 are carried onto the rails 15 of the pair of rotating members 12 and 12 of the mold transfer device 4, and then on the first transfer means 2 After the metal frames 1 and 1 on both the left and right sides of the mold transfer device 4 are clamped and fixed by the two clamp mechanisms 33 and 34 (see FIG. 1), the metal frames 1 on the pair of rotating members 12 and 12 are fixed. Is clamped by the clamp mechanism 14 (see FIG. 1).
次いで、シリンダ２２・２２の伸長作動により一対の把持部材２１・２１を下向きに回動させて閉じ、一対の回動部材１２・１２上の上下鋳型Ｍ等を一対の把持部材２１・２１とで把持し、続いて、エンコーダ３１の管理の下に一対の回動部材１２・１２の反転角度を制御しながら、減速機付きモータ１１の正転駆動により回転軸９を介して一対の回動部材１２・１２を第１移送手段２から振動コンベヤトラフ３に回動させて、上下鋳型Ｍを反転しながら第１移送手段２から振動コンベヤトラフ３に旋回移動させる（図９参照）。次いで、シリンダ２２・２２の収縮作動により一対の把持部材２１・２１を上向きに回動させて開き、把持機構２１・２１による上下鋳型Ｍの把持状態を解く。これにより、反転した上下鋳型Ｍを一対の把持部材２１・２１を介在させて振動コンベヤトラフ３上に自重落下させ、上下鋳型Ｍを第１移送手段２から振動コンベヤトラフ３に移し替える。 Subsequently, the pair of gripping members 21 and 21 are closed by rotating the cylinders 22 and 22 downward, and the upper and lower molds M on the pair of rotating members 12 and 12 are closed with the pair of gripping members 21 and 21. Subsequently, the pair of rotating members are controlled via the rotating shaft 9 by the forward rotation of the motor 11 with a speed reducer while controlling the reversal angles of the pair of rotating members 12 and 12 under the control of the encoder 31. 12 and 12 are rotated from the first transfer means 2 to the vibrating conveyor trough 3, and the upper and lower molds M are turned and swung from the first transferring means 2 to the vibrating conveyor trough 3 (see FIG. 9). Next, the pair of gripping members 21 and 21 are rotated upward by the contraction operation of the cylinders 22 and 22 to open, and the gripping state of the upper and lower molds M by the gripping mechanisms 21 and 21 is released. As a result, the inverted upper and lower molds M are dropped by their own weight onto the vibrating conveyor trough 3 with the pair of gripping members 21 and 21 interposed therebetween, and the upper and lower molds M are transferred from the first transfer means 2 to the vibrating conveyor trough 3.
なお、こうして、上下鋳型Ｍを反転しかつ一対の把持部材２１・２１を介在させて振動コンベヤトラフ３に自重落下させることにより、上下鋳型Ｍ内の鋳物素材は、湯口部が下になって把持部材２１．・２１上に落ちるとともに、把持部材２１・２１によって誘導されて振動コンベヤトラフ３に進入するため、鋳物素材の本体部分に打痕が生じるのを未然に防ぐことができる。 In this way, the casting material in the upper and lower molds M is gripped with the pouring gate down by inverting the upper and lower molds M and dropping them onto the vibrating conveyor trough 3 with a pair of gripping members 21 and 21 interposed therebetween. Member 21. Since it falls on 21 and is guided by the gripping members 21 and 21 to enter the vibrating conveyor trough 3, it is possible to prevent the dents from being formed in the main body portion of the casting material.
上下鋳型Ｍの第１移送手段２から振動コンベヤトラフ３への移し替え完了後、減速機付きモータ１１の逆転駆動により一対の回動部材１２・１２を振動コンベヤトラフ３から第１移送手段２の元の位置に戻し、続いて、クランプ機構１４による金枠１のクランプ状態を解いて一サイクルを終了する。 After the transfer of the upper and lower molds M from the first transfer means 2 to the vibrating conveyor trough 3 is completed, the pair of rotating members 12 and 12 are moved from the vibrating conveyor trough 3 to the first transferring means 2 by the reverse drive of the motor 11 with a speed reducer. After returning to the original position, the clamp state of the metal frame 1 by the clamp mechanism 14 is released, and one cycle is completed.
なお、上記の実施例では第１移送手段２は、レール６と、レール６上に走行自在に装架された複数の走行台車７・７とで構成したが、これに限定されるものではなく、例えば、複数のパレットと、これらのパレットを移送可能に装架したつば付きローラコンベヤとで構成してもよい。
またなお、上記の実施例では第２移送手段として振動コンベヤトラフ３を用いたが、上下鋳型を誘導するシュートでもよい。
In the above embodiment, the first transfer means 2 is composed of the rail 6 and the plurality of traveling carriages 7 and 7 that are movably mounted on the rail 6. However, the present invention is not limited to this. For example, a plurality of pallets and a roller conveyor with a collar on which these pallets are mounted so as to be transportable may be used.
In the above embodiment, the vibrating conveyor trough 3 is used as the second transfer means, but a chute for guiding the upper and lower molds may be used.
