It consists of
そして、前記振動式分離機構5においては、箱状の分離槽9が設けてあり、この分離槽9内の下部には砂粒子が通過可能な大きさのスリットを多数設けた板部材10が張架して装着してあり、さらに前記分離槽9の側壁における前記板部材10の一側端である左端には鋳型補助具および異物を排出させる第1排出口(図示せず)が、また、前記分離槽9の側壁における前記第1排出口とほぼ対向する位置には前記分離槽9の底面の延長線上に位置して砂粒子を排出させる第2排出口(図示せず)がそれぞれ形成してある。そして、前記第1排出口には蓋部材(図示せず)が、また前記第2排出口にはゲート部材(図示せず)がそれぞれ取り付けてある。また、前記分離槽9の外側面における前記第1排出口および前記第2排出口の下端位置には、第1シュート11および第2シュート12がそれぞれ装着してある。
In the vibration type separation mechanism 5, a box-shaped separation tank 9 is provided, and a plate member 10 provided with a large number of slits of a size through which sand particles can pass is stretched in the lower part of the separation tank 9. Further, the left end which is one side end of the plate member 10 on the side wall of the separation tank 9 has a first discharge port (not shown) for discharging a mold auxiliary tool and foreign matter, A second discharge port (not shown) for discharging sand particles is formed at a position substantially opposite to the first discharge port on the side wall of the separation tank 9 and is located on an extension line of the bottom surface of the separation tank 9. It is. A lid member (not shown) is attached to the first outlet, and a gate member (not shown) is attached to the second outlet. Moreover, the 1st chute | shoot 11 and the 2nd chute | shoot 12 are each mounted | worn in the lower end position of the said 1st discharge port and the said 2nd discharge port in the outer surface of the said separation tank 9.
また、前記アンバランスウェイト式振動手段6においては、前記振動式分離機構5の分離槽9における前後両側の外面に、2個の振動モータ13・13が回転軸を前後方向へ指向させるとともに同一線上に位置させて装着してあり、しかも、前記振動モータ13・13の回転軸線が、前記板部材10および第1・第2シュート11・12を含む前記分離槽、前記加振部材7、前記破砕機構8、前記振動モータ13・13、前記鋳枠Fおよび鋳枠F内の注湯後の砂鋳型を含んで前記空気ばね4・4に支持された振動物体全体の重心を通り、さらに、前記2個の振動モータ13・13は、アンバランスウェイトが等速度で時計回り方向の正転と反時計回り方向の逆転とに回転するようになっている。 In the unbalanced weight type vibration means 6, two vibration motors 13, 13 are arranged on the same line on the outer surfaces of the front and rear sides of the separation tank 9 of the vibration type separation mechanism 5 while directing the rotation shaft in the front-rear direction. And the axis of rotation of the vibration motors 13 and 13 includes the plate member 10 and the first and second chutes 11 and 12, the separation tank, the vibration member 7, and the crushing member. Including the mechanism 8, the vibration motors 13 and 13, the casting frame F, and the sand mold after pouring in the casting frame F, passing through the center of gravity of the entire vibrating object supported by the air springs 4 and 4, and The two vibration motors 13 and 13 are configured so that the unbalanced weight rotates at a constant speed in the forward direction in the clockwise direction and the reverse direction in the counterclockwise direction.
したがって、前記板部材10および第1・第2シュート11・12を含む前記分離槽9を、前記アンバランスウェイトの正回転により、リサージュ図形が時計回り方向の略円を描くように振動させて鋳型補助具および異物を第1シュート11へ、また、前記アンバランスウェイトの逆回転により、リサージュ図形が反時計回り方向の略円を描くように振動させて砂粒子を第2シュート12へそれぞれ移送することができるようになっている。 Therefore, the separation tank 9 including the plate member 10 and the first and second chutes 11 and 12 is vibrated so that the Lissajous figure draws a substantially circle in the clockwise direction by the normal rotation of the unbalance weight. The auxiliary tool and the foreign matter are vibrated to the first chute 11 and the Lissajous figure is vibrated so as to draw a substantially counterclockwise circle by the reverse rotation of the unbalance weight, thereby transferring the sand particles to the second chute 12. Be able to.
次に、このように構成した振動式砂鋳型ばらし装置を用いて、注湯後の砂鋳型内在の鋳枠Fから砂鋳型を分離するとともに、分離した砂鋳型を粉砕して鋳型補助具および異物と、砂粒子とに区分けする手順について述べる。第1排出口を蓋部材によって閉じ、かつゲート部材によって第2排出口の開口度を適当な大きさにした状態の下に、注湯後の砂鋳型内在の鋳枠Fを支持部材2・2上に載せた後、2個の振動モータ13・13を逆転駆動して2対のアンバランスウェイトを反時計回り方向の逆転方向に等速度で回転させると、加振部材7・7、破砕機構8、振動式分離機構5における板部材10および第1・第2シュート11・12を含む分離槽9等は、リサージュ図形が反時計回り方向の略円を描くように振動される。
Next, the sand mold is separated from the casting mold F in the sand mold after pouring using the vibratory sand mold spreading device configured as described above, and the separated sand mold is pulverized to mold auxiliary tools and foreign matters. And the procedure to classify into sand particles is described. Under the condition that the first discharge port is closed by the lid member and the opening degree of the second discharge port is set to an appropriate size by the gate member, the casting frame F in the sand mold after pouring is supported by the supporting members 2 and 2. After placing on the top, when the two vibration motors 13 and 13 are driven in reverse to rotate the two pairs of unbalanced weights in the counterclockwise reverse direction at a constant speed, the vibration members 7 and 7 and the crushing mechanism 8. The separation tank 9 including the plate member 10 and the first and second chutes 11 and 12 in the vibration type separation mechanism 5 is vibrated so that the Lissajous figure draws a substantially circle in the counterclockwise direction.
これにより、まず、加振部材7・7によって鋳枠Fや砂鋳型等に水平方向と垂直方向の2方向から成る振動が加わり、これに伴って、鋳型補助具を含んだ砂鋳型や異物が鋳枠F内から分離して破砕機構8上に落下し、続いて、砂鋳型は、破砕されて砂塊状態となった後、鋳型補助具、異物等と一緒に、振動式分離機構5の分離槽9内に落下する。
As a result, first, vibrations 7 and 7 are applied to the casting frame F, sand mold and the like in two directions, ie, horizontal and vertical directions. The sand mold is separated from the inside of the casting frame F and dropped onto the crushing mechanism 8, and then the sand mold is crushed into a sand lump state, and then the vibration type separating mechanism 5 It falls into the separation tank 9.
振動式分離機構5の分離槽9内に落下した砂塊、鋳型補助具、異物等は相互に激突して砂塊は粉砕されて砂粒子化する。砂粒子化して成る砂粒子は、板部材10の多数のスリットを通過して分離槽9の底面上に落下した後、この底面上を右方へ移動して第2排出口から第2シュート12を介して排出される。上述の工程が繰り返されて適宜の時間が経過した後、2個の振動モータ13・13を正転駆動して2対のアンバランスウェイトを時計回り方向の正転方向に等速度で回転させると、振動式分離機構5における板部材10および第1・第2シュート11・12を含む分離槽9等は、リサージュ図形が時計回り方向の略円を描くように振動されて、分離槽9の板部材10上に残留していた鋳型補助具、異物等は板部材10上を左方へ移動して第1排出口から第1シュート11を介して排出される。 Sand lump, mold auxiliary tool, foreign matter and the like dropped in the separation tank 9 of the vibration type separation mechanism 5 collide with each other, and the sand lump is crushed into sand particles. The sand particles formed into sand particles pass through many slits of the plate member 10 and fall on the bottom surface of the separation tank 9, and then move rightward on the bottom surface to cause the second chute 12 from the second discharge port. It is discharged through. After an appropriate time has elapsed after the above steps have been repeated, when the two vibration motors 13 and 13 are driven in the forward direction to rotate the two pairs of unbalanced weights at a constant speed in the clockwise direction. The separation tank 9 including the plate member 10 and the first and second chutes 11 and 12 in the vibration-type separation mechanism 5 is vibrated so that the Lissajous figure draws a substantially circular shape in the clockwise direction. Mold auxiliary tools, foreign matters, and the like remaining on the member 10 move leftward on the plate member 10 and are discharged from the first discharge port via the first chute 11.
