Food dough cutting method and cutting apparatus

Abstract

The object of the present invention is to provide a food dough cutting method and cutting device thereof capable of forming conveyed food dough strips that have nearly identical weight per unit time when dividing band shaped food dough into multiple food dough strips in the conveyance direction, and is further capable of performing the same number of cuts for each food dough strip when cutting each food dough strip along the width direction into food dough pieces having a specified weight. The conveyed food dough is aligned to a position that is displaced by just an alignment displacement amount with respect to a reference position that is based on the installation position of cutting members. The alignment displacement amount is calculated based on the ratio of the width dimension of the food dough and the lengths of food dough pieces that are cut from food dough strips on both sides.

1 . A food dough cutting method comprising steps of:
 conveying band shaped food dough by way of a conveyor;   detecting both end positions of the food dough by way of a food dough detection device;   calculating the center position and width dimension of the width of the food dough by way of a control device based on the detection signal;   aligning the center position of the width and the conveyance position of the food dough by way of an alignment device;   dividing the band shaped dough into multiple food dough strips in the conveyance direction by way of cutting members that are downline from the conveyor; and   cutting each food dough strip into food dough pieces having a specified weight by way of a food dough piece cutting device; wherein   the conveyance position is a position that is displaced just an alignment displacement amount with respect to a reference position that is based on the installation position of the cutting members; and   the alignment displacement amount is calculated by way of the control device based on the ratio of the width dimension of the food dough and the lengths of food dough pieces that are cut from food dough strips that are located on both sides.   
   
   
       2 . A food dough cutting method comprising steps of:
 conveying band shaped food dough by way of a conveyor;   detecting both end positions of the food dough by way of a food dough detection device;   calculating the center position and width dimension of the width of the food dough by way of a control device based on the detection signal;   aligning the center position of the width and the conveyance position of the food dough by way of an alignment device;   dividing the band shaped dough into multiple food dough strips in the conveyance direction by way of cutting members that are downline from the conveyor; and   cutting each food dough strip into food dough pieces having a specified weight by way of a food dough piece cutting device; wherein   the conveyance position is a position that is displaced just an alignment displacement amount with respect to a reference position that is based on the installation position of the cutting members; and   the alignment displacement amount is calculated by the control device based on the ratio of the width dimension of the food dough and the number of cuts per unit time when cutting the food dough strips located on both sides by the food dough piece cutting device.   
   
   
       3 . A food dough cutting device comprising:
 a conveyor that conveys band shaped food dough;   a dough width detection device that detects both end positions of the food dough;   a control device that calculates the center position and width dimension of the width of the food dough based on the detection signal from the dough detection device;   an alignment device that aligns the center position and conveyance position of the width of the food dough; and   a multiple-strip cutting device that is located downline from the conveyor and that comprises cutting members that divide the food dough into multiple food dough strips in the conveyance direction; and   a food dough piece cutting device that cuts the food dough strips into food dough pieces having a specified weight; wherein   the conveyance position is a position that is displaced just an alignment displacement amount with respect to a reference position that is based on the installation position of the cutting members;   the alignment displacement amount is a value that is calculated based on the ratio of the width dimension of the food dough and the lengths of food dough pieces that are cut from food dough strips that are located on both sides; and   the control device controls the operation of the alignment device according to the alignment displacement amount.   
   
   
       4 . A food dough cutting device comprising:
 a conveyor that conveys band shaped food dough;   a dough width detection device that detects both end positions of the food dough;   a control device that calculates the center position and width dimension of the width of the food dough based on the detection signal from the dough detection device;   an alignment device that aligns the center position and conveyance position of the width of the food dough; and   a multiple-strip cutting device that is located downline from the conveyor and that comprises cutting members that divide the food dough into multiple food dough strips in the conveyance direction; and   a food dough piece cutting device that cuts the food dough strips into food dough pieces having a specified weight; wherein   the conveyance position is a position that is displaced just an alignment displacement amount with respect to a reference position that is based on the installation position of the cutting members;   the alignment displacement amount is a value that is calculated based on the ratio of the width dimension of the food dough and the number of cuts per unit time when cutting the food dough strips located on both sides by the food dough piece cutting device; and   the control device controls the operation of the alignment device according to the alignment displacement amount.
