装置に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a post-processing device for crushing a foundry sand mold to separate mold sand from a cast product, and in particular, it relates to a post-processing device that crushes a foundry sand mold and separates the mold sand from the cast product, and in particular, it reliably crushes unpoured sand molds. The present invention relates to a post-processing device that can effectively prevent mold sand from flowing out by crushing it.
（従来の技術）
鋳造用砂型を粉砕して型砂と鋳造製品とを分離させる従
来の後処理装置としては例えば、シェークアウトマシン
がある。(Prior Art) An example of a conventional post-processing device for crushing a casting sand mold to separate mold sand and a cast product is a shakeout machine.

ッパにより下方のコンベヤ上に落とす一方、鋳造製品を
トラフ上で送って別のコンベヤに引き渡すという機能を
なす。A shakeout machine usually has a trough, which is a transfer table, with a lattice-shaped receiver and a hopper below it, and by vibrating the trough diagonally up and down, the material is extracted from the flask by a punch-out device. In addition to crushing the sand mold containing the cast product that fell onto the trough, the lumpy mold sand adhering to the cast product is broken down, the mold sand and the cast product are separated, and the mold sand is passed through the receiving member. Its function is to drop the cast product onto a conveyor below by means of a hopper, while sending the cast product on a trough to be delivered to another conveyor.
そして、各コンベヤは、型砂と鋳造製品とをそれぞれ搬
出し、型砂は回収、再利用サイクルにより処理されて再
利用される一方、鋳造製品は仕上げ加工される。Each conveyor then carries out the mold sand and the cast product, respectively, and the mold sand is processed and reused in a recovery and reuse cycle, while the cast product is finished.
（発明が解決しようとする課題）
ところで、鋳造ライン中の何らかの不具合により注湯装
置が溶湯の注湯を行わなかった未注湯の鋳造用砂型が、
そのままラインを流れてシェークアウトマシンに供給さ
れることがある。(Problem to be Solved by the Invention) By the way, a sand mold for casting that has not been filled with molten metal, where the pouring device did not pour molten metal due to some malfunction in the casting line,
It may flow directly through the line and be supplied to the shakeout machine.
そして、粘土質系粘結材を使用している砂型は、未注湯
で熱を受けていないと高い強度を保ったままとなる。Sand molds that use clay-based caking materials retain their high strength unless they are poured with metal and exposed to heat.
しかしながら、前記シェークアウトマシンは、トラフを
振動させる振動数を変更する機能を持たず、従ってその
振動数が一定である。However, the shakeout machine does not have a function of changing the frequency at which the trough is vibrated, and therefore the frequency is constant.

定になり鋳造製品の品質に悪影響が出るという問題があ
った。For this reason, in the shake-out machine, it is not possible to sufficiently collapse and crush the unpoured sand mold, and therefore, the lumpy mold sand is sent on the trough and the mold sand is transferred to the conveyor for discharging the product. There was a problem in that the amount of mold sand in the casting line fluctuated and the properties of the mold sand became unstable, which adversely affected the quality of the cast product.
しかも、単純にシェークアウトマシンの振動数を上げて
加振力を増加させるだけでは、正常に注湯が行われた砂
型を粉砕する際に鋳造製品同士の当たりが激しくなって
変形や傷つきが生ずるおそれがあった。Moreover, simply increasing the vibration frequency of the shakeout machine to increase the excitation force will cause the cast products to hit each other violently, causing deformation and damage when the sand mold that has been properly poured is crushed. There was a risk.
