Thereafter, when good brown rice falls into the bag, the amount of good brown rice dropped into the bag is displayed as a measured value, and this measured value does not include the weight of the bag. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a shutter operating device according to the present invention will be specifically described with reference to the drawings. First, the automatic grain weighing machine according to the present invention is integrally attached to a rice sorting machine (A) as shown in FIG. 3, and the sorted good brown rice once stored in a storage tank (1) is sequentially stored therein. It is to be bagged. That is, the brown rice fed from the huller as shown by the arrow (a) is sorted by the rotary sorting cylinder built in the body of the rice sorter (A), and the small rice is taken out from the exit (8). While the brown rice from which the small rice has been removed is stored in the storage tank (1), the shutter (3) is fully opened, partially opened and fully closed, and the set amount is set in the bag placed on the weighing scale (9). It is to be packed. Next, the structure of the shutter (3) will be described with reference to FIGS.
This will be described in detail below. A supply port (2) is opened at a lower portion of the storage tank (1), and a shutter (3) is provided with two fan-shaped support plates (1).
0) has a bottom surface (11) having a curved surface with an arc-shaped cross section, and the upper ends of both support plates (10) are storage tanks (1).
A handle (13) pivotally supported by a protruding body (12) protruding from one side of the lower side is integrated with the upper end as an axis,
Move under the supply port (2) to open and close the supply port (2),
Further, a holding member (14) formed by bending a plate body is attached to the bottom surface (11). On the other hand, (4) is a support attached to the other side on the lower side of the storage tank (1). The support (4) has a built-in solenoid (7), and the solenoid (7) reciprocates. The member (6) is a spring (15) when the solenoid (7) is energized.
And when it is not energized, it returns by the force of the spring (15). Therefore, the configuration for energizing the solenoid (7) will be described. There are two paths for supplying electricity to the solenoid (7), a path for automatically supplying electricity by weighing with a weighing scale and a path for supplying electricity manually through a main power supply and a power switch (S). The shutter (3) can be closed by the manual operation through the solenoid (7). Further, the upper end of a shutter arm (5) is pivotally connected to the support (4), and a part of the shutter arm (5) is connected to the reciprocating member (6). At the same time, the engaging portion (1
6) When (17) is formed and the reciprocating member (6) is moved back, the shutter (3) is attached to the holding member (14).
, Each engaging portion (16) or (17) is engaged, and is disengaged and disengaged by forward movement. When the holding member (14) engages with the middle engaging portion (16), the shutter (3) opens the supply port (2).
Is held fully open, and when the holding member (14) engages with the engaging portion (17) at the lower end, the holding member (14) is held in a partially open state, and the engaging portions (16) of the holding member (14) are held. And (17) is completely closed. As described above, the handle (13) is pushed down as shown by the arrow (b), and the holding member (14) is moved to the middle position against the spring (15) while moving the shutter (3) upward. When the shutter (3) is engaged with the engaging portion (16), the shutter (3) maintains the fully open state as shown by the imaginary line (C), and the good brown rice stored in the storage tank (1) is supplied to the supply port (2). ) And is supplied into a bag placed on a weighing scale (9). Then, when the good brown rice in the bag approaches the set amount, the solenoid (7) is momentarily energized from the automatic energizing path, and the reciprocating member (6) moves forward as shown in (d). After disengagement, the spring (15) moves back as shown in (e). At this time, the shutter (3) moves down by its weight, and the holding member (1) is attached to the engaging portion (17) at the lower end of the shutter arm (5) where the shutter (3) has moved back.
4) is engaged, and as shown by the solid line in FIG. 1, the shutter (3) keeps the supply port (2) partially open and drops little by little. When the weighing scale (9) weighs the set amount of good brown rice, the solenoid (7) is automatically energized again, and the reciprocating member (6) moves forward again to move the shutter arm (5). Retreat as shown by the imaginary line (f), and hold the holding member (1
The engaging portion (17) is disengaged from (4), and the shutter (3) becomes a virtual line (G), and the supply port (2) is fully closed. In this way, the shutter (3) repeats full opening, partial opening and full closing to sequentially fill a bag placed on the weighing scale (9) with a set amount. Further, even if the brown rice in the storage tank (1) is exhausted during the weighing operation and the weighing operation is completed, the shutter (3) can be kept fully open or partially open. Is operated by pressing the "OFF" button of the power switch (S) provided on the operation panel (P) through the manual power supply path, the power of the operation panel (P) is turned off, and at the same time, the solenoid (7) is energized and the shutter arm is turned on.
