METHOD FOR CONTROLLING AUTOMATIC ROOT-CUTTING APPARATUS FOR HEAD-FORMING VEGETABLE

摘要

PROBLEM TO BE SOLVED: To control an automatic root-cutting apparatus for headforming vegetables and improve the quality, labor-saving performance and work efficiency by automatically controlling the cutting height of the cutting apparatus based on an approximate expression showing the head heights before and after cutting. ;SOLUTION: This automatic root-cutting apparatus A for head-forming vegetable is provided with a transfer apparatus 1 for transferring a head-forming vegetable B directing its root B1 upward, a head-height measuring device 17 to measure the height from the root part B1 to the top and a cutting apparatus 4 to cut the root part B1 of the vegetable B. The test measurements consisting of the measurement of the head-height xi before cutting the root B1, the cutting of the root part B1 by manual control and the measurement of the height yi after cutting are repeated several times. The cutting apparatus A is controlled by automatically controlling the cutting height Y of the cutting apparatus 4 based on an approximate expression showing head heights xi and yi before and after cutting, e.g. Y=aX+b [ (a), (b), the correlation coefficient (r), Mx and My are defined in the following sheet; X and Y are head height (automatic) before and after cutting; (i) is number of measurements].;COPYRIGHT: (C)1999,JPO
