Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a yield control device in a rice milling machine, which is provided with a weight scale for supplying rice upstream of a rice milling machine and a scale for rice milling downstream thereof. .

Conventional technology Conventionally, there has been a grain yield measuring device that measures the yield by installing conveyor flow rate indicators upstream and downstream of a grain milling machine, reading the instantaneous value of the flow rate at any time, and measuring the flow rate ratio. 33-
It is known as Publication No. 12881.

Further, a raw grain quantity limiting type weighing machine is provided upstream of the grain milling machine, and a refined grain quantity limiting type weighing machine is provided downstream thereof, and each of the grains obtained by receiving the quantity limiting operation of each of the weighing machines is provided. A milled grain yield measuring device equipped with an electric automatic calculator that calculates the weighing period or the ratio of the weighed integrated amount is also known as Japanese Patent Publication No. 39-28515.

Further, a grain milling machine is inserted and arranged between the raw material grain weighing machine and the refined grain weighing machine, and these are connected as a series flow path, so that the raw material grain weighing machine and the refined grain weighing machine are connected to each other as a serial flow path. A grain milling yield control device for a grain milling machine that automatically adjusts the milling load based on the weighing ratio of both weighing machines is also known as Japanese Patent Publication No. 39-28512.

In these devices, in order to make the rice milling yield value obtained in this way an appropriate yield value, the resistance value of the resistor cover provided at the rice milling outlet of the rice milling machine was controlled. .

However, in yield control based on changes in the resistance value of the resistor lid of the rice mill, there is a large time difference between the change in the resistance value of the resistor lid and the resulting change in the yield of the rice mill. Even if the resistance value of the resistor lid is changed to correct the yield obtained by comparing the rice milling weight scale downstream of the machine to an appropriate value, the rice will continue to be milled with an incorrect yield for the time it takes to reach the appropriate yield value. In the resulting milled rice, there are many grains with incorrect yield values, which deteriorates the quality of the milled rice.If rice with incorrect yield values is eliminated to avoid this, there are disadvantages such as a large number of parts to be removed and a decrease in rice milling efficiency. had.

In addition, if the yield is corrected only using the supplied rice weighing scale and the rice milling weighing scale, the weight of grains existing between each weighing scale will be too small, making it impossible to obtain a more accurate average yield, and adjusting the rice milling machine. is also not accurate,
It was not possible to improve yield measurement accuracy.

Problems to be Solved by the Invention It is an object of the present invention to eliminate the above-mentioned drawbacks and to improve the weight of the supplied rice upstream of the rice milling machine compared to the conventional rice milling machine in which the yield is controlled by changing the resistance value of the resistor lid. Based on the rice milling yield value obtained from the rice milling weight meter downstream of the rice milling machine, the yield of the rice milling machine can be automatically and quickly controlled to an appropriate value, improving rice milling quality and eliminating defects. Rice milling efficiency can be improved by reducing the amount of milled rice with an appropriate yield value as much as possible. By using this assumption as a correction value, it is possible to calculate the average yield from the start of work to any point in time, obtaining a more accurate average yield, and improving the accuracy of yield measurement in rice milling equipment. An object of the present invention is to provide a yield control device.

It is possible to improve the rice milling quality by controlling the amount of rice milled, and to improve the rice milling efficiency by reducing the amount of milled rice with an inappropriate yield value as much as possible.

In addition, the rice milling yield calculation device is connected to the supply rice weight scale and the rice milling weight scale, respectively, and the holding of rice grains is performed between the calculation device connected to the supplied rice weight integration measurement device and the milled rice weight integration measurement device, and the above-mentioned both scales. Since it has a capacity correction input device, the weight of grains existing between the supply rice weight scale and the rice milling weight scale, that is, the holding capacity, is appropriately assumed in advance and used as a correction value. By inputting this correction value into the correction input device, it is possible to calculate the average yield from the start of the work day to any point in time, and a more accurate average yield can be obtained, and the rice milling machine can be adjusted according to the accurate yield. By correcting the correction value based on the actual product at the end of each day, the accuracy of yield measurement can be further improved.
