Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a hopper for receiving grain, a batch-type weighing machine for weighing the weight of grain to be fed, and a method for transferring grain from the hopper to the weighing machine. This invention relates to a weighing device for grain processing equipment equipped with a conveying means for supplying grain.

[Conventional technology]

In this type of grain processing equipment described above, the receiver must weigh the amount of grain received at each receiving location. Since a batch type weighing machine is used, the grain cannot be inputted for weighing to the next recipient unless the grain in the weighing machine is completely discharged.

By the way, in the past, for example, a plurality of tanks were installed between the hopper and the weighing machine to temporarily store the grain received from the hopper, so that the next grain could be weighed while the previous one was being weighed. Efficiency has also been improved by making it possible to temporarily store grains and shorten the time it takes to start receiving the next grain after weighing.

[Problem to be solved by the invention]

However, due to the structure of batch-type weighing machines, it is not possible to start loading the next grain to be weighed until the grain has been discharged from the machine. Receiving goods from loading to completion of weighing was not sufficient to improve overall processing efficiency.

The present invention has been made in view of the above circumstances, and its purpose is to improve the efficiency of the entire cargo receiving process.

[Means to solve the problem]

A weighing device for grain processing equipment according to the present invention includes a hopper for receiving grain, a batch-type weighing machine for weighing the weight of supplied grain, and a conveying means for supplying grain from the hopper to the weighing machine. The features and configuration are as follows.

A first characteristic configuration is that a plurality of the weighing machines are provided, and the conveying means includes a flow path switching unit that switches which of the plurality of weighing machines is to supply the grain.

The second characteristic configuration is to switch the weighing machine that supplies grain from the currently measuring weighing machine to another weighing machine when the increase rate of the measured value of the weighing machine that is currently weighing becomes less than a set value. The present invention is characterized in that a control means is provided for operating the flow path switching section based on the measurement information of the weighing machine.

[For production]

In the first characteristic configuration, by providing a plurality of weighing machines and switching the grain supply to them,
When grain is received, it is weighed. In other words, when - of the weighing machines completes the weighing process, in other words, when the supply of grain to one weighing machine ends, even if the discharge of weighed grain from that weighing machine has not yet been completed, the next This allows grain feeding to the weighing machine to begin.

By the way, the process of switching the weighing machine that supplies grain from the one currently weighing to another weighing machine may be performed manually by a worker while checking the status of the weighing process of the weighing machine, for example. , it is also possible to have it performed automatically.

In other words, in the second characteristic configuration, when the increase rate of the weight value of the currently weighing weighing machine becomes less than or equal to the set value, the weighing machine that supplies grain is switched from the currently weighing weighing machine to another weighing machine. I'm trying to switch it up.

〔Effect of the invention〕

In the first characteristic configuration, the time required from grain receiving to completion of weighing is reduced compared to the conventional method, and the efficiency of the entire grain receiving process can be improved.

In the second characteristic configuration, the weighing machine that supplies the grain can be automatically switched, so that the receiver can further improve the efficiency of weighing in the process.

〔Example〕· Embodiments of the present invention will be described below based on the drawings.

As shown in Figures 3 to 6, the grain processing equipment consists of a plurality of tanks for storing grain (1) and a square building (2) in plan view in which grain processing machinery is housed. It consists of
There are entrances and exits (3A) on both sides of the building (2), (3B)
), and a cargo receiving section (3) is provided adjacent to one side of the entrances and exits (3A) and (3B).

The building (2) is constructed using the tank (1) as a support. That is, so that the plurality of tanks (1) form the outer wall of the building (2),
They are arranged in two rows with an interval between them. As shown in FIG. 7, on the top of the tank (1),
The roof frame (5A) or the frame is fixed, and this roof frame (5A)
A roofing material (58) is placed and fixed on top of 5A), thereby forming a roof (5) that covers the interior space of the tank (1) and the building (2). Further, a frame (4) assembled with aggregate is erected on the ground, and the lower part of the tank (1) is supported by the frame (4). With that, the building (2)
The interior space is now used as an installation space (6) for grain processing machinery, offices, etc.

Each of the tanks (1) has a lower end formed in a conical shape tapering downward in side view, and the lower end of the conical shape is supported by the frame (4) in a state above the ground. ing. Grain is input from above, and stored grain is discharged from the lower end.

By the way, among the plurality of tanks (1), the cargo receiving tank is located adjacent to the section (3), but the cargo receiving tank is used as a storage tank (IA) and is located at the innermost part of the building (2). The tank (1) located between the receiving tank (IA) and the tempering tank (IB) stores the grain after drying. The installation position is determined depending on the purpose of use, such as when used as a silo (IC).

To explain, the cargo receiving department (3) is the building (2).
Since this cargo receiving area is located close to the entrance/exit (3A) of the tank (I), this cargo receiving area is located closest to the storage tank (I
By arranging A), the receiver can carry out his work efficiently.

In addition, since the continuous flow type dryer (C3) for drying grains needs to exhaust hot air and dust generated by the flow of grains outside the building, the cargo receiving area is located farthest from the part (3). It will be installed adjacent to the inner wall of the building (2) where it will be installed.

Since the grains are circulated and dried between the dryer (C3) and the tempering tank (IB), the dryer (C3) and the tempering tank (IB)
Regarding B), the efficiency of the drying process will be better if they are placed closer together. Therefore, the tank (1) located at the innermost part of the building (2) is used as a tempering tank (IB).

However, the cargo receiving tank (IA) and the tempering link tank (IB) have their internal spaces divided into four sub-tanks (7) along the circumferential direction in plan view. It is configured such that each of these sub-tanks (7) can be used separately.

If we take the tank (IA) as an example, the cargo receiver is the seventh tank.
As shown in Figures and Figure 8, the four auxiliary tanks (7)
The upper receiver has an inlet (8) and a lower outlet (10), respectively.
), and these upper receivers are equipped with an electromagnetically operated switching valve (
9) is provided in the upper part of the internal space, and an electromagnetically operated shutter (11) is provided in the lower part to switch which of the lower discharge ports (10) the grains are to be discharged from. In addition, in the figure, (12) is each sub-tank (7).
This is a ventilation duct for blowing air into the inside of each. However, this ventilation duct (12)
1), and is not attached to the tempering tank (IB). Also, (AIO)
(B1) is a lifting line using a packet conveyor for lifting the loaded grain to the upper part of the building; (B1) is a lifting line that uses a packet conveyor to transport the loaded grain to the upper part of the building; The grain supply line (D6) using a screw conveyor is a first conveyance line forming a part of the grain conveyance line (D) using a belt type flow conveyor.

To explain the machinery for grain processing, as shown in Fig. 1, the three grain receivers attached to section (3) are a hopper (A1) and a hopper (Al).
) A tank (A4) that temporarily stores the grains received from the container.
A rough separator (86) for removing foreign matter such as straw from the grain discharged from the tank (A4);
) The two receiving machines are a batch-type weighing machine (A8) that weighs the grains discharged from the machine, and a machine that switches between the rough sorting machine (86) and which weighing machine (A8) the grains are fed to. Receiving equipment equipped with a switching valve (A7) as a flow path switching unit, drying equipment such as the dryer (C3),
Sorting machine (F4), hulling adjustment device (Fl), stone removing machine (F2)
), shipping weighing machine (F15), multiple shipping brown rice containers (Fil), etc. and,
As mentioned above, these machines are connected to the plurality of tanks (1
) is arranged three-dimensionally (multi-story) using the internal space (6) of the building (2) surrounded by the building (2).

Next, a description will be given of a transport route for transporting grain between the cargo receiving tank (IA), the tempering tank (IB), and the silo (IC).

The undried grains received from the hopper (Al) are transported laterally by the line (A2) and then transferred to the building (2) by the first lifting line (A3). The goods are transported upward and stored in the storage tank (A4), and then the coarse sorter (86) removes foreign matter such as straw waste. will be weighed by one of the commercial weighing machines (A8).

In other words, the cargo receiving line (A2) and the first lifting line (83) constitute a conveying means.

The flow rate of grain passing through the rough sorter (86) gradually increases with time from the time when the grain is received and supplied to the rough sorter (86), and the grain supply continues. During this period, the flow rate is constant according to the supply amount, and after the supply is stopped, the flow rate gradually decreases to zero as time passes.

However, since the rough separator (80) is designed to process grains that are fed first by pushing out grains that are fed later, the flow rate after the supply is stopped is such that the residual amount is small. (As the flow rate decreases, it will take a long time to reach completely zero.)

As a result, the amount of grains delivered to the weighing machine (A8) decreases from the time when the grain discharge from the storage tank (A4) is completed until the time when the processing in the rough sorter (A6) is completed. Grain will continue to be supplied. Incidentally, the time required for the grains remaining in the rough sorter (A6) to be completely discharged is approximately the same as the time required for the receiver to transport the grains from the hopper (A1) to the tank (A4). It looks like this.

Therefore, if the next receiving grain does not start processing until the grain received earlier has completely passed through the coarse sorter (86), the processing of the receiving receiving material will actually be reduced to approximately 50%. There is a disadvantage that it becomes a rate.

Therefore, when the amount of grain passed through the coarse sorter (86) becomes small, that is, when the increase in the grain supply to the weighing machine (A8) is small, the weighing machine that supplies the grain (
A8) is forcibly switched from the currently weighing weighing machine to another weighing machine, and processing of the next consignment is started.

By the way, if the switching valve (A7) is switched before the grain supply to the weighing machine (A8) is completely completed, the amount of grain that was received earlier remains in the coarse sorter (A6). This amount is added to the grains that will be placed next in the receiver and will be weighed, but some of the grains that will be placed next in the receiver will remain in the rough sorter (A6) due to the supply stoppage. As a result, no measurement error occurs. However, when the equipment starts operating, the rough separator (A
6) Since there is no grain remaining in the coarse sorter (80), the grain received first will be weighed to be less than the amount remaining in the coarse sorter (80), or the amount of remaining grain can be determined in advance and the weighed value This is not a problem as it can be corrected.

Therefore, in this embodiment, the process of switching the switching valve (A7) is automatically performed based on the weighing information of the weighing machine (A8). In addition, in Figure 1, (A9
) is a control device constituting a control means for automatically switching the switching valve (A7).

To explain, as shown in Fig. 2, when the amount of grain discharged from the coarse sorter (80) begins to decrease due to the stoppage of grain supply, the weighing value of the weighing machine (88) The rate of increase (R) in (W) will also begin to decrease. Therefore, this measured value (W) is sampled at every set time (1), and as shown in the following formula, the measured value (W(0)) before and after the sampling.

The increase rate (R) is determined from the difference between
8) A weighing machine (A8) that starts the weighing process and supplies the grain when it is determined that the grain input has been completed.
The company is trying to switch to another weighing machine.

The weighed grains discharged from the weighing machine (A8) are again lifted to the upper part of the building by the second lift line (AIO), and the grains are transferred to the above-mentioned container via the transport line (B1). The consignment will be stored in the tank (IA).

The grains stored in the tank (lA) of the cargo receiver are discharged from the lower end thereof and transported by the first transport line (D6) and the subsequent second transport line (D7) that constitute the grain transport line (D). It passes below the silo (IC), is transported to the front side of the tempering tank (IB), and is then lifted to the upper part of the building by the third lifting line (D, 12). .

The grain lifted above the building by the third lifting line (C12) can be switched between being sent to a shipping process or a drying process by a switching valve (013).

When sent to the drying process, it is lifted upward by a fourth lifting line (C7) used for drying and stored in the tempering tank (IB). However, the grains lifted upward by the fourth lifting line (C7) are either stored in the tempering tank (IB) by the switching valve (C8) or stored in the silo (IC).
You can also switch between storing them.

The grains stored in the tempering tank (IB) are
The dryer (1
6).

To explain the drying conveyance line (C), there is a third conveyance line (C1l) that transversely conveys the grains discharged from the lower end of the tempering tank (IB), and a
A fifth lifting line (C1) lifts the grain that has been cross-fed to the terminal end of the conveyance line (C1l) to above the dryer (C3), and the fifth lifting line (CI) lifts the grain to the top of the dryer (C3). a switching valve (C) for switching between feeding the dried grains into the dryer (C3) or transporting them to the silo (IC);
2), and a fourth conveyance line (C6) that conveys the grains discharged from the lower end of the dryer (C3) to the lower end of the fourth lifting line (C7) in order to return them to the tempering tank (IB). ).

To explain the grain conveyance line (D), the cargo receiver has a tank (IA) and a tempering tank (IB).
The grain discharged from the lower end of the silo (IC) disposed between a conveyance line (D6), the second conveyance line (D7), the third lift line (C12),
And, passing through the switching valve (C13), the fourth lifting line (C7) and its switching valve (C8), which constitute the drying line (C), and the fifth lifting line (C2) and its switching valve (C8), which constitute the drying line (C), are connected. The silo (IC) is connected via the switching valve (C2).

I) and can be returned to the silo (Ic).

However, the grain conveyance line (D) is for grain conveyance between the receiving tank (IA) and the silo (IC) located on the opposite side to the side where the tempering tank (IB) is located. In order to be able to carry out the same operation, a seventh conveyance line (D8) that cross-feeds the grain discharged at the lower end of the silo (Ic) on the opposite side, an eighth conveyance line (D9) that follows it, and the eighth conveyance line. A sixth lifting line (DlO) lifts grains upward from (D9), and a ninth transport line (DlO) transports the lifted grains horizontally and joins the starting end of the third lifting line (C12). Dll), the receiver is equipped with a tank (IA) and a tempering tank (IB).
6th conveyance line (old) above the silo (IC) between )
The 10th conveyance line (D2) conveys the grain to the upper part of the silo (IC) on the opposite side via the

It branches and passes through a flow control tank (El), a pre-cleaner (F2), and a switching valve (F3) to the sorting machine (F4) or the sales weighing machine (F5).
).

However, the grain discharged from the sorting machine (F4) can also be conveyed to the sale weighing machine (F5).

The grains weighed by the sales weighing machine (F5) are transported above the building by a seventh lifting line (F8), and then transported to the hulling adjustment device (Fl). .

However, a switching valve (F9) is provided at the end of the seventh lifting line (F8), and the seventh lifting line (F8) is connected to the upper part of the building via the eighth lifting line (EIO). The lifted grain can also be returned to the silo (IC) by joining the 11th conveyance line (DI) above the silo (IC).

The grain discharged from the hulling adjustment device (Fl) is transported above the building via the stone removal machine (F2) on the ninth lifting line (F4), and then via the switching valve (F5). It is designed to be transported to the weighing tank (F5) of the shipping weighing machine (F15) or the brown rice weighing machine (F6).

The grains discharged from the brown rice weighing machine (F6) are
The brown rice is transported upward by the lifting line (F9) and transferred to multiple brown rice tanks (Fil) via the 12th transport line (FIO).
) are arranged and stored in predetermined amounts.

The grains discharged from the brown rice tank (Fil) are
From the 3 transport line (Fl2), it is discharged onto the loading platform of a transport truck and shipped.

However, although not described in detail, the grains discharged from the brown rice weighing machine (F6) are sent to the so-called flexible container ring (F8) by the switching valve (F7) and do not go through the brown rice tank (Fil). It is also possible to ship it.
