Description

[Detailed Description of the Invention] (a) Field of Industrial Application In the present invention, the upper end is pivotally attached to a shutter provided at a supply port at the bottom of a storage tank, and a support body that can be attached to the lower side of the storage tank. An engaging member, which is connected to a reciprocating member that operates in a related manner by measuring a set amount, and the supply port is fully opened / partially opened / fully closed by engaging / disengaging the engaging member and the shutter. The present invention relates to a supply shutter device for automatic grain measurement, in which the grains in the storage tank are sequentially bag-switched by switching to.

(B) Conventional technology As described above, the supply port is fully opened / partially opened / fully closed by connecting to the reciprocating member that is related to the operation of the set amount and engaging / disengaging the engaging member and the shutter. The supply shutter device for automatic grain weighing, which is switched to, is conventionally, for example,
It is well known from JP-A-59-174486.

By the way, such a supply shutter device opens the supply port fully to close the set amount when the bag is packed, so that the grain can be supplied quickly. The amount that is set exactly matches the set amount.

However, when it is partially opened and dropped from the feed port little by little, the gap (C1) with the shutter on the closed side of the feed port becomes small as shown in FIG. The supply cannot be expected.

In addition, as a method for adjusting the opening area to be wide or narrow by superimposing a plurality of shutters having a constant opening, the method disclosed in Japanese Utility Model Laid-Open No. 57-12639
The publication No. 1 has been published, but the one disclosed in this publication is composed of a plurality of shutters and a plurality of drive devices for operating the shutters, and the structure is complicated and the cost is high. It was lacking.

(C) Problem to be solved by the invention As described above, in the conventional configuration, when the supply port is partially opened and the grains in the storage tank are dropped and supplied little by little, the gap on the closed side of the supply port is small. Therefore, depending on the type of grain, smooth supply is not performed, and although the opening area can be adjusted widely, the present invention has a complicated structure. With the aim of providing a simple and easy-to-use structure that allows a single shutter to be used even for a variety of cereals, the accuracy of bagging amount and the improvement of work efficiency can be improved. It is an improved one.

(D) Means for Solving the Problem Therefore, in order to achieve the above-mentioned object, the present invention provides one shutter provided at the supply port at the bottom of the storage tank and a support attached to the lower side of the storage tank. The body comprises an engaging member having an upper end pivotally attached, and the engaging member is connected to a reciprocating member that is associated with a set amount of measurement to connect the engaging member and the shutter to disengage the supply port. When switching between fully open / partially open / fully closed, the width of the supply port in the direction orthogonal to the opening / closing direction of the shutter is set to be narrower on the closed position side than on the open position side of the shutter, and part of the supply port This is because the distance between the shutter and the shutter when opened is large.

(E) Action With this configuration, when the shutter is fully opened,
The engagement member is engaged with the shutter to maintain the fully opened state, and the grain in the storage tank drops from the supply port and is supplied into the bag.
When the grain in the bag reaches near the set amount, the reciprocating member moves forward and disengages from it, so that the shutter moves downward due to its weight.At that time, the engaging member moves back. It engages with the shutter that moves downwards and holds the supply port in a partially open state, drops it little by little from the supply port, and when the set amount is packed in the bag, the reciprocating member moves forward. The shutter comes to come off, and the shutter completely closes the supply port.

In this way, the supply port is fully opened, partially opened, and fully closed by the shutter, and the set amount is sequentially packed into bags.
When the shutter is partially opened and dropped and supplied little by little, the grain in the storage tank is narrowed at the shutter closing position and the feed opening width is narrowed. It is smoothly dropped and supplied little by little from the supply port formed while being kept large.

(F) Embodiment Hereinafter, the present invention will be specifically described with reference to an embodiment drawing.

The supply shutter device shown in this example is, as shown in FIG. 3, integrally attached to the rice sorter (A), and the good brown rice after selection is temporarily stored in the storage tank (1) and sequentially packed into bags. It is for automatic grain weighing.

That is, the brown rice fed from the hulling machine as shown by the arrow (a) is sorted by the rotary sorting cylinder installed in the body of the rice sorting machine (A), and the small rice is taken out from the outlet (7). The good brown rice after being removed is stored in the storage tank (1) and the shutter (3) is fully opened / partially opened / closed to be packed into a bag placed on the weighing scale (9) by a set amount. It has become so.

Next, the details will be described with reference to FIGS. 1 and 2.

A supply port (2) is opened in the lower portion of the storage tank (1), and a shutter (3) has a bottom surface (11) having a curved surface with an arcuate cross section between both fan-shaped support plates (10). The upper ends of both support plates (10) are pivotally supported by a projecting body (12) projecting to one side of the lower side of the storage tank (1), and are integrated with a handle (13) so that the upper ends serve as shafts and supply ports ( A holding member (14) formed by bending a plate is attached to the bottom surface (11) by moving the lower side of (2) to open and close the supply port (2).

(4) is a support attached to the other lower side of the storage tank (1). The support (4) has a solenoid (S).
Is incorporated, and the reciprocating member (6) is a solenoid (S).
When it is energized, it moves forward against the spring (17), and when it is not energized, it moves back by the force of the spring (15).

An upper end of an engaging member (5) is pivotally attached to the support (4), a part of the engaging member (5) is connected to the reciprocating member (6), and a shutter (3) is provided. ) Side engaging parts (16) (17) are formed in the middle part and the lower end part, and when the reciprocating member (6) returns, the holding member (14) on the shutter (3) side is The engaging portion (16) or (17) is engaged, and is disengaged by the forward movement to be disengaged.

Then, when the holding member (14) engages with the engaging portion (16) at the middle portion, the shutter (3) holds the supply port (2) in a fully opened state, and the engaging portion (17) at the lower end portion. When the holding member (14) is engaged, the holding member (14) is held in a partially opened state, and when the holding member (14) is disengaged from the engaging portions (16) (17), it is in a fully closed state.

Further, a regulating body (7) is provided on the side of the supply port (2) close to the shutter (3), and the regulating body (7) is provided on both sides in the example shown in FIG. 3) Supply port width (W) in the direction orthogonal to the opening / closing movement direction
Is configured such that the closed position side is narrower than the open position side of the shutter (3), and the holding member (14) engages with the engaging portion (17) at the lower end portion as described above, so that the shutter (3) is When the partially open state is maintained, the closing side of the bottom surface (11) of the shutter (3) substantially coincides with the end surface (18) of the restricting body (7), and the restricting body (7) is moved as described above. ) Narrows the width (W) of the supply port and widens the distance (C) from the shutter (3) to partially open the supply port (2).

Therefore, while pushing down the handle (13) as shown by the arrow (b) and moving the shutter (3) upward, the holding member (14) is engaged with the engaging portion (16) in the middle part against the spring (15). When combined, the shutter (3) is kept fully open as shown by the phantom line (C), and the good brown rice stored in the storage tank (1) falls from the supply port (2) and is placed on the weighing scale (9). When it is supplied into the placed bag and the amount of good brown rice in the bag reaches the set amount, the solenoid (S) is momentarily energized and the reciprocating member (6) moves forward as shown in (d). After releasing the engagement, the spring (15) forces it to move back like (e).

At that time, the shutter (3) is moved downward by the weight of the shutter (3), and the holding member (14) is engaged with the engaging portion (17) at the lower end of the engaging member (5), which is shown by the solid line in FIG. Thus, the shutter (3) holds the supply port (2) in a partially opened state, and drops it little by little.

In this case, the shutter (3) is closed on the closed side of the supply port (2) while the width (W) of the supply port is narrowed by the restricting body (7).
The closed side of the bottom surface (11) substantially conforms to the end surface (18) of the restricting body (7) and is reduced to a shape with a large distance (C) from the shutter (3). In this state, it is dropped and supplied from the supply port (2).

Then, when the weighing scale (9) weighs a set amount, the solenoid (S) is energized, the reciprocating member (6) moves forward, and the engaging member (5) is held as shown by an imaginary line (f). Material (1
The engagement portion (17) is disengaged from 4), and the shutter (3) becomes like a virtual line (g) to fully close the supply port (2).

(G) Advantageous Effect of the Invention As described in detail above, the present invention has one shutter provided at the supply port of the lower part of the storage tank, and the upper end pivotally attached to the support member which can be attached to the lower side of the storage tank. An engaging member, which is connected to a reciprocating member that operates in a related manner by measuring a set amount, and the supply port is fully opened / partially opened / fully closed by engaging / disengaging the engaging member and the shutter. In this configuration, the width of the supply port in the direction orthogonal to the opening / closing movement direction of the shutter is narrower on the closed position side than on the open position side of the shutter, and the gap between the supply port and the shutter is partially opened. Since it is made large, the supply port of the storage tank is fully opened / partially opened / closed by the shutter and the set amount is sequentially packed, but the shutter remains partially opened. And when you drop and supply little by little, Grain in the storage tank, the width of the supply port is narrowed on the side where the shutter is closed, and instead, the product is smoothly dropped and supplied little by little from the supply port formed by keeping the gap with the shutter large. Therefore, the accuracy of the bag packing amount can be ensured, the drop supply of any kind of grain can be smoothed, and the work efficiency can be improved, and the present invention allows this to be performed by one shutter. Therefore, there is an advantage that the configuration is simple and the cost is low.
