METHOD AND DEVICE FOR CUTTING FOOD SHEET

PROBLEM TO BE SOLVED: To provide a method and device for cutting a food sheet, capable of efficiently manufacturing hexahedrons with the entire faces being cut out from a food sheet by a machine.SOLUTION: A cutting device 60 includes a belt conveyor 65, a first vibration cutter 70A which peels the upper surface layer from the upper surface of a food sheet S, a second vibration cutter which peels the lower surface layer from the food sheet, a cutter 100 for cutting in the crosswise direction having a plurality of rotary blades 102, and a cutter 110 for cutting the food sheet in the lengthwise direction with predetermined intervals. Preferably the cutting device 60 further includes upper surface layer-peeling means which peels the upper surface layer so as to be taken out, both side layer-peeling means which peels both of the side layers so as to be taken out, hexahedron collecting means which separates the hexahedrons disposed on the lower surface layer from the lower surface layer so as to be collected, and lower surface layer peeling means which peels the lower surface layer from the belt conveyor 65 so as to be taken out. 【課題】食品シートから全面カットされた六面体を、機械的に効率良く製造することができる、食品シートの切断方法及び切断装置を提供する。【解決手段】この切断装置６０は、ベルトコンベヤ６５と、食品シートＳの上表面から上表面層を剥離する第１振動カッター７０Ａと、食品シートから下表面層を剥離する第２振動カッターと、複数の回転刃１０２を有する幅方向切断カッター１００と、食品シートを長さ方向に所定間隔で切断する長さ方向切断カッター１１０とを備えている。更に、上表面層を剥離して取り出す上表面層剥離手段と、両側面層を剥離して取り出す両側面層剥離手段と、下表面層上に配置されている六面体を下表面層から分離して回収する六面体回収手段と、下表面層をベルトコンベヤ６５から剥離して取り出す下表面層剥離手段とを備えていることが好ましい。【選択図】図６
