MUD MATERIAL SUPPLY DEVICE AND CONTROL METHOD OF MUD MATERIAL SUPPLY DEVICE

To prevent an increase in production cost due to provision of an extrusion part for extruding a row of mud materials at each stage in the height direction, and to suppress the failure of the mud materials.SOLUTION: A mud material supply device includes: loading parts 11-17 each having a partition plate 10j for partitioning a row of mud materials M of first and second stages; a first extrusion part for executing a first extrusion operation for extruding a row of mud materials M of the first stage; a switching mechanism 50 for switching the partition plate 10j between a supporting state for supporting a row of mud materials M of the second stage and a non-supporting state; and a control unit. The control unit executes the first extrusion operation on the row of the first stage mud materials M, switches the partition plate 10j of the loading parts 11-17 in which the first extrusion operation is executed from the support state to the non-support state, drops the row of the second stage mud materials M to the first stage, and controls the first extrusion operation to be executed on the row of the mud materials M dropped on the first stage.SELECTED DRAWING: Figure 7 【課題】高さ方向の各段にマッド材の列を押し出す押出し部を設けることによる製造コストの増加を防止し、かつマッド材が破損することを抑制する。【解決手段】１段目と２段目のマッド材Ｍの列を仕切る仕切板１０ｊを有する積載部１１－１７と、１段目のマッド材Ｍの列を押し出す第１押出し動作を実行する第１押出し部と、２段目のマッド材Ｍの列を支持する支持状態と非支持状態とに仕切板１０ｊを切り替える切替機構５０と、制御部と、を備え、制御部は、１段目のマッド材Ｍの列に対して第１押出し動作を実行し、第１押出し動作が実行された積載部１１－１７が有する仕切板１０ｊを支持状態から非支持状態に切り替えて２段目のマッド材Ｍの列を１段目に落下させ、１段目に落下したマッド材Ｍの列に対して第１押出し動作を実行するよう制御するマッド材供給装置を提供する。【選択図】図７
