Well accommodated. Further, the bran generated in the rice milling machine body 14 during the rice polishing is sucked by the blower fan 16 through the suction duct 16b (see FIG. 4), and then the side portion 41 of the rice milling machine body 41.
A is discharged to the bran collection tank 42 through the discharge path 16c provided through the a and collected. Here, when the weight of the bran collected in the bran collecting tank 42 is small, as shown in FIG. 6, the force acting on the contact member 28 of the bran detecting means 25 from the bran collecting tank 42 is applied by a spring. 38 is smaller than the urging force of the contact member 28.
Keeps the posture of the posture detection sensor 39 away from the contact 39a, and the warning lamp 49 does not blink. On the other hand, when the bran accumulates in the bran collecting tank 42 at a predetermined weight or more, the force acting on the abutting member 28 of the bran detecting means 25 from the bran collecting tank 42 increases. Is also large, as shown in FIG.
The contact member 28 retreats to the rice milling equipment main body 41 side against the urging force of the spring 38, the contact member 28 contacts the contact 39a of the posture detection sensor 39, and the posture detection sensor 39 is turned on. As a result, this state is detected by the control unit, and the warning lamp 49 blinks. Therefore, the rice bran recovery tank 42
When the rice bran has accumulated the predetermined weight, the staff can easily confirm that the warning lamp 49 is blinking. In this case, the staff or the like removes the bran recovery tank 42 from the rice polishing equipment main body 41.
, And the operation of discharging the bran from the bran collection tank 42 can be easily performed. Therefore, the bran collection tank 4
2 can be prevented from accumulating too much bran, and as in the conventional case, the air flow deteriorates, the suction force by the blower fan 16 decreases, and the bran adheres to the white rice milled by the milling machine body 14. This is prevented from remaining as it is, and the reliability of rice polishing is improved. Since the rice bran detecting means 25 is provided not in the rice bran recovery tank 42 but in the rice milling equipment main body 41, wiring to the posture detecting sensor 39 of the rice bran detecting means 25 is easy. Since the abutment member 28 of the bran detecting means 25 is configured to abut against the side surface 43a of the bran collecting tank 42, the bran detecting means 25 can have a simple and compact configuration. There is no need to protrude too much, and there is no problem such as hitting the staff of the staff when the attachment / detachment operation of the bran collection tank 42 is performed. That is, for example, the bran recovery tank has a double structure of an outer tank and an inner tank, and the inner tank is supported by a spring provided on the bottom of the outer tank. If a structure that detects with the sensor provided on the bottom part of the is used, the weight of the entire inner tank is supported by the spring, so the spring and the supporting part of this spring must be large and strong. At the same time, a connection terminal with the rice milling equipment main body must be provided as a wiring portion for supplying power to the sensor, and a complicated and large space-consuming mechanism and complicated wiring equipment are required. As another example, a support arm is provided which protrudes below the rice bran recovery tank from the rice milling equipment main body side, and a spring for receiving a bottom portion of the rice bran recovery tank is provided on the support arm. It is conceivable to provide a sensor on the arm for detecting the downward movement of the bran collection tank. However, in this case as well, since the weight of the entire bran recovery tank is supported by the spring, a spring and a large supporting arm for supporting the spring must be used, and the supporting arm and the spring must be used. Will protrude greatly from the rice milling equipment main body, and this will cause a problem such as hitting the foot of a staff member during the attachment / detachment operation of the bran recovery tank. On the other hand, according to the milling equipment 40, since the attitude detection sensor 39 is provided in the rice milling equipment main body 41, wiring to the attitude detection sensor 39 is easy, and the contact member 28 abuts against the side surface of the bran collecting tank 42, and only a small part of the weight of the bran collecting tank 42 acts on the abutting member 28. Therefore, the spring 38 for urging the abutting member 28 also has a small urging force. In addition to the standard one, the bran detecting means 25 may be a simple one that does not require much strength. In addition, since the bran detecting means 25 does not have to protrude much from the rice polishing equipment main body 41, the bran collection tank 4
There is no problem such as hitting the foot of a staff member during the attaching / detaching operation of 2. In the above-described embodiment, the case where the bran recovery tank 42 is arranged on the side of the rice milling equipment main body 41 has been described. However, the present invention is not limited to this.
The bran recovery tank 42 may be arranged such that the abutment member 28 of the bran detecting means 25 abuts on a vertically extending surface, such as behind 1, and receives only a part of the weight of the bran collection tank 42. Also, the case of the warning lamp 49 has been described as a warning means, but the present invention is not limited to this. For example, when a warning device such as a buzzer is issued, or when this rice milling equipment is connected to a management computer, The management computer may be notified of information indicating that a predetermined weight of bran has accumulated in the bran collection tank 42. As described above, according to the present invention, a bran detecting means for detecting that a predetermined weight or more of bran has accumulated in a bran collecting tank, and a bran detecting tank connected to the bran detecting means, Warning means for notifying that the bran has accumulated above a predetermined weight,
By providing the rice bran in the rice bran recovery tank, if the bran accumulates in the bran recovery tank by a predetermined weight or more, this state is detected by the bran detection means and notified by the warning means. You don't have to look at the pool,
No more hassle. In addition, since too much bran is prevented from accumulating in the bran recovery tank, the air flow deteriorates, the suction power of the blower fan decreases, and the white rice milled by the rice milling machine body as in the past. The rice bran does not remain as it is attached, and the reliability of the milling process is improved. Furthermore, since the rice bran detecting means is provided in the rice milling equipment main body, even when an electric part such as a sensor is provided in the rice bran detecting means, wiring to this electric part becomes easy. Further, the bran collecting tank is locked to the rice milling equipment main body by a locking means on the upper side thereof, and as a bran detecting means, the bran collecting tank can freely protrude from the rice milling equipment main body side to the bran collecting tank side. A contact member contacting an outer surface portion extending vertically on the lower side of the rice bran collecting tank through the contact member by urging the contact member in a direction in which the contact surface protrudes toward the bran collecting tank side. Urging means for urging the outer surface portion in a direction away from the rice milling equipment main body, and attitude detecting means for detecting that the contact surface of the contact member has receded to a predetermined position on the rice milling equipment main body side. Because only a part of the weight of the bran recovery tank acts on the contact member that contacts the side surface of the bran collection tank, the spring that biases the contact member has a small urging force. As well as
As the bran detecting means, a simple one that does not require much strength is sufficient, and the production cost can be minimized. Further, the rice bran detecting means does not have to protrude much from the rice milling equipment main body, so that there is no trouble such as hitting a staff member's foot when the rice bran collecting tank is attached / detached, and the safety is well maintained.
