Description

Description: BACKGROUND OF THE INVENTION The present invention relates to an apparatus for roughly selecting and weighing received cereals, and a storage for selecting and storing cereals based on cereal classification and conditions. The present invention relates to a grain receiving device provided with a device and the like.

2. Description of the Related Art Grain receiving devices such as rice centers are equipped with a large number of storage bins for storing cereals.The received kernels are sorted according to the classification and conditions such as moisture content and varieties, and storage corresponding to the sorting is performed. They are put into bottles and stored.

As shown in FIG. 4, the grain receiving device usually includes a receiving device A and a storage bin device B having a plurality of storage bins, a weighing device C and a control device D disposed therebetween. And the respective steps are communicated via a transport path.

The receiving apparatus A includes a roughing machine 102 that removes dust in the grains received from the receiving hopper 101.

The weighing device C includes a preliminary hopper 103a that receives coarsely-selected grains and a weighing unit 103b that measures the moisture content and weight of the grains in a batch manner.

The storage bin side device B includes a plurality of storage bins for storing grains.
104a-104f, a belt conveyor 108a, and drop openings 117a-117f and shutters 116a- corresponding to each of the plurality of storage bins.
A flow conveyer 108b having a 116f is provided.

After receiving, the grains that have been roughly selected and weighed by the roughing machine 102 and the weighing device 103 are dropped onto the belt conveyor 108a of the switching conveyance path 109 via the bucket conveyor 107, and further via the belt conveyor 108a. , Which are dropped on the flow conveyor 108a above the storage bins into which the grains are put, and which are selected in advance by the classification and conditions of the grains.
The shutter 116 of the loading port 117 is opened, and is loaded into any one of the plurality of storage bins 104a to 104f.

As the control device D, a normal control device including a memory, a microprocessor, an input / output unit, and the like is used. In FIG. 4, reference numeral 110 denotes a belt conveyor that conveys the grains discharged from the storage bins 104a to 104f to the next step.

As shown in FIG. 3, the weighing device C receives the grains from the roughing machine 102 into the preliminary hopper 103a, and when the shutter 111 of the preliminary hopper 103a is opened, the grains are put into the weighing unit 103b. Is done. Then, when the weight of the grain reaches a predetermined amount set in advance and the weighing scale 112 detects this, the shutter 111 of the preliminary hopper 103a is closed, and the feeding of the grain to the weighing unit 103b is stopped. At this time, the weight of the grains in the measuring device is precisely calculated again by the weighing scale 112, while the moisture content is measured by the moisture meter 113, and the values are transmitted to the control device D.

When these weighing processes are completed, the shutter 114 provided at the lower portion of the weighing unit 103b is opened, and the kernels after the weighing process are discharged. When the discharging is completed, the shutter 114 is closed, and the shutter of the preliminary hopper 103a is again closed. 111 is opened so that grains are put into the measuring section 103b.
The grains discharged from the roughing machine 102 while the shutter 111 of the preliminary hopper 103a is closed are gradually stored in the preliminary hopper 103a, but during this operation, the preliminary hopper 103a becomes full. Then, the level detection sensor 115 provided above the preliminary hopper 103a detects this, and the receiving operation is temporarily stopped.

On the other hand, in such a configuration, since measurement data (moisture, weight, etc.) is required for each cargo port, one weighing unit 10
One line of receiving hopper 101 and roughing machine 1 for 3b
In the configuration of 02, the next loading port cannot be loaded until the grain is loaded into the loading hopper and the measurement process is completed.

Further, at this time, it is necessary to completely discharge the grains inside the roughing machine and then to put in the next cargo port, but the sorting operation by the roughing machine requires time until the end. One of the causes is that, in the latter half of the sorting, when the amount of grain is reduced, a so-called chorochoro state may occur, resulting in poor discharge efficiency.

Therefore, the worker has a waiting time until the weighing process of the previously received kernel is completed, and the worker cannot continue the receiving operation. The fact that a certain amount of time is required from the receipt of the product to the end of the weighing can be considered as a waiting time factor on the receiving side when viewed from the whole grain receiving device.

Further, when there is a change in the cargo port, it is necessary to switch the storage bin according to the classification and conditions of the receiving kernel. At this time, all of the grains being transported by the belt conveyors 105 and 108a, the bucket conveyors 106 and 107, and the flow conveyor 108b used for the transport means have been dropped into the selected storage bins, and then the discharge shutters of the flow conveyor 108b. 116
And its transfer direction. But for this,
Requires a waiting time of 60 to 90 seconds.

If the shutter 114 of the weighing unit 103b is opened during this waiting time, the grain will be mixed into the storage bin 104 whose classification and conditions do not conform, so that the shutter 114 cannot be opened. Since it is full, it becomes impossible to continue the receiving operation. As described above, the switching of the storage bin is a waiting time factor on the storage bin side in the whole grain receiving device.

These are major causes of congestion in the receiving work in rice centers and the like where grains having various types and conditions are harvested during the harvest season. Also, this is one of the various reasons that the receiving operation could not be automated.

[Problems to be solved by the invention]

The occurrence of a waiting time in the cereal receiving apparatus has a problem that cereals can be manually input, but the main factors of the apparatus are the above-described waiting time element on the receiving side and the waiting time element on the storage bin side.

In large grain drying and storage facilities (rice centers, etc.), the receiving hopper is located near the entrance of the building and the roughing machine and the weighing device are located near the storage bins. It must be communicated on the device that the cereals move between
Usually around a minute. On the other hand, the time required to switch the storage bin is usually about 60 to 90 seconds. Further, since the processing on the storage bin side is performed after the processing on the receiving side, the switching operation of the storage bin can be performed to some extent between the start of the processing of the grain by the receiving side and the end. That is, regarding the waiting time, the waiting time factor on the receiving side is dominant.

Therefore, an object of the present invention is to eliminate the waiting time in the grain receiving device and to reduce the processing time on the receiving side.

[Means for solving the problem]

Receiving device A, weighing device C and storage bin device B
And constitute a grain receiving device.

The receiving apparatus A is provided with a plurality of receiving hoppers, the same number of roughing machines, the same number of adjusting tanks, and a grain conveying path leading to the weighing device C.

 The weighing device C is provided with a single weighing device.

The storage bin device B is provided with a plurality of storage bins in a post-process of the measuring device.

The same number of roughing machines and the same number of adjusting tanks as the multiple receiving hoppers are one hopper, one roughing machine and one adjusting tank.
In the previous process of the adjustment tank, a roughing machine that roughly sorts the grain conveyed from the cargo receiving hopper is arranged, and a single cargo receiving line is configured. Connected configuration.

The number of the plurality of receiving lines depends on the number of cargo ports concentrated at one time and the economical efficiency. However, from the viewpoint of smooth grain processing, the time (t) required from one receiving line to the end of weighing in one receiving line is considered. Depends on the number and quantity of consignments carried into Regardless of whether the number is large or the amount is large, the number of receiving lines is increased so that at least one receiving line is always ready to receive.

The grains that are successively put into a plurality of receiving lines are roughly sorted by a roughing machine provided in each receiving line, and then temporarily stored in a preparation tank of the receiving apparatus A, and then sequentially discharged and weighed. It is transferred to the device C and measured.

It is assumed that the processing capacity of the weighing device C is larger than the ability to put grains into the receiving hopper. For example, the measurement process for three lots can be completed within the time for putting one lot of grains into the receiving hopper 10.

Grains are continuously loaded into the receiving line,
After passing through the roughing machine, it enters the preparation tank and moves to the scale. In other words, even if multiple receiving lines are working at the same time (during loading, moving to the adjustment tank or weighing),
One of the plurality of hoppers is ready for charging.

The weighed grains are fed into a preset storage bin via a grain transport path.

〔Example〕

 Hereinafter, examples of the present invention will be described.

 First, a first embodiment will be described.

The grain receiving device includes a receiving device A as shown in FIG.
A storage bin side device B and a weighing device C are provided.

The receiving apparatus A has six receiving hoppers 10 (a) to 10 (a).
(F), six roughing machines 40 '(a) to 40' (f) and
Equipped with six adjustment tanks 40 (a) to 40 (f), each of which comprises one load receiving hopper 10, a roughing machine 40 'and an adjustment tank 40, and constitutes one load receiving line. It has receiving lines (a) to (f). Receiving hopper 10 and roughing machine 40 'are belt conveyors 20 (f) to 20 (f)
And the bucket conveyors 30 (a) to 30 (to). Since the roughing machine 40 'and the adjusting tank 40 are arranged in a substantially vertical direction, no special conveying means is required for conveying the grains between these devices. Receiving device A and weighing device C described later
Is a single screw conveyor that can be removed from the center
50 and a bucket conveyor 60 are connected.

Similar to the conventional example, the storage bin side device B has a plurality of storage bins 110a to 110e for storing cereals, shutters 90a to 90e corresponding to the plurality of storage bins, and discharge ports 90'a to 90'e. It is composed of a flow conveyor 100. The belt conveyor 120 is a conveyor for taking out from the storage bin.

The weighing device C is composed of a measuring device 70 including a preliminary hopper 70a and a weighing unit 70b, similarly to the conventional type. Since the preliminary hopper 70a and the measuring section 70b are arranged in a substantially vertical direction, no special transport means is required.

The transfer capacity between the receiving hopper 10 and the adjustment tank 40 is 6 T / H. 1 line, the transfer capacity between the screw conveyor 50 and the storage tank 110 is 30 T / H, and the grain is discharged from the adjustment tank 40. The time required to reach the preliminary hopper 70a is 15 seconds, and the time required to be discharged from the weighing unit 70b and reach the storage bin 100 is 60 seconds including the storage tank switching time due to the difference in classification and conditions. .

Suppose now that there are 13 or more consignments, where the receiving weight of one lot is 1 ton.

FIG. 2 is a time chart showing an operation state of the present grain receiving device. The horizontal axis indicates the passage of time, and the vertical axis indicates the amount of processed cereals.

The solid line a represents the first one lot [first kernel lot (1) to sixth kernel lot (6)] in each of the adjustment tanks 40 (a) to (f) in each of the receiving lines (a) to (f). ] Indicates the integrated amount of the kernel when the kernel is input. Therefore, after the elapse of 10 minutes (elapsed time: 10 minutes), 6 tons of kernels are stored in each of the 1 ton kernels in each of the adjustment tanks (a) to (f) through the roughing machine. The first input takes place simultaneously.

A dashed line C indicates the processing amount in the measuring unit 70b. The weighing starts with a certain amount of grains deposited in the adjustment tank 40, that is, about 8 minutes and 20 seconds in elapsed time, and divides it into predetermined lots several times to calculate one lot and calculate one lot. Each time the amount is measured, it is sent to the storage bin. Time required is 1
It takes about 40 minutes and ends in 10 minutes. For this,
The one-dot chain line indicating the accumulated grain amount in the storage bin starts at an elapsed time of about 9 minutes and 20 seconds and rises. The transfer to the measuring section 70b is performed sequentially from the load receiving line (a) to the load receiving line (f).

On the chart line, between the points b and c, the weighing unit 70b
This is the time required for weighing the last specified amount of the kernel lot (1) and sending it out to the storage bin.

When the measuring unit 70b becomes empty at the time point c, the adjustment tank 40 in the second receiving line (b) is continuously operated.
The grain of (b) is transferred to the measuring section 70b. The time between the points c and d is a time during which the kernel cannot be sent to the adjustment bin side because the first specified amount of the kernel in the receiving line (b) [second kernel lot (2)] is being measured. is there.

Hereinafter, similarly, the weighing up to the receiving line (f) and the sending out to the storage bin are performed.

After 10 minutes, the receiving line (a) becomes empty, so that the seventh grain lot (7) can be undertaken. This state is successively continued to the receiving line (f) with a time interval between point b and point c on the chart. That is, at least one cargo receiving line is always free, and there is no need to interrupt the cargo receiving.

The seventh grain lot (7) is processed in the same manner as the first grain lot (1), but the chart diagram shows the change in the input amount in each of the receiving lines (a) to (f). Emphasis is placed on the display at the start of the insertion, and point b is the starting point. Therefore, the end point is near the elapsed time of 20 minutes.

Similarly, the chart lines of the eighth kernel lot (8) and the ninth kernel lot (9) also start at points e and f, respectively. For example, assuming that the integrated amount of the kernel amount in the eighth kernel lot (8) is expressed, the point e as the starting point is the point b.
It is necessary to move vertically from the upper part to the lower part on the extension of the point c.

With the above configuration, the receiving hoppers 10 (a) to 10
(F) When the grain lots (1) to (6) are thrown in one after another, in each of the receiving lines (a) to (f),
The grains are coarsely selected and temporarily stored in the adjusting tanks 40 (a) to 40 (f).

1st grain lot put into adjustment tank (1)
Is immediately transferred to the weighing device C and the weighing operation is started. The first kernel lot (1) for which the weighing operation has been completed is sequentially transferred to the storage tank. When the weighing operation of the first kernel lot (1) is completed, the seventh kernel lot (7) can be put into the receiving hopper 10 (a) because the receiving line (a) is empty. About 60 seconds after the completion of the weighing operation, the charging of the first grain lot (1) to the selected one of the storage tanks 110a to 110e is completed. Adjustment tank 40 from this time
The grain lot (2) of (b) is transferred to the weighing device C and the next weighing operation (2) starts.

In this way, the operations of roughing, weighing, and storage are successively performed, and the adjustment tanks (b), (c), and (c) are finished while the grain lot (7) is put into the adjustment bin via the receiving hopper.
The measurement and storage operations of the kernel lots (2), (3), and (4) of (d) are sequentially completed, and the kernel lots (8), (9), (1)
0) can be received.

At this time, the weighing unit 70b of the weighing device C receives the grains from the adjustment tank located in the post-process of the roughing machine in each of the receiving lines (a) to (f). In addition, after the fourth kernel lot (4), more than 10 minutes have passed since the kernel was put into the receiving hopper 10 and the weighing was started.
In other words, when weighing the grains after the fourth grain lot (4), the roughing machine in the preceding process has already finished the so-called chorochoro stage and has completely discharged. On the other hand, since the transfer from the adjustment tank 40 to the measuring section 70b does not have the inefficient state like the so-called chorochoro, the weighing time is affected by the inefficiency of the rough sorting machine having time until the end of the sorting. I do not receive.

In addition, since the switching of the storage bin side is about 60 seconds, when the classification and conditions of the consignment change, the information is input to the control device at the beginning of the consignment, and the first consignment of the consignment is received.
The waiting time can be reduced by, for example, starting switching during the weighing of the specified amount of times, and overlapping the required time for switching with the weighing time.

Therefore, many cargo ports can be continuously received without waiting for the processing of one kernel lot to be completed.

〔The invention's effect〕

According to the conventional example, unless the weighing operation of the previous lot and the charging to the storage bin are completed, the next lot cannot be received.However, according to the present invention, the grain receiving device is always in a state capable of receiving, There is no waiting time and there is no interruption in the receiving work.

In addition, the grain from the roughing machine, which takes time to finish sorting, is completely transferred to the adjustment tank early after the operation of the grain receiving device, and the weighing device separates the grain from the adjustment tank in this state. Because it is well received, it is possible to eliminate the influence of the inefficiency of the roughing machine when feeding grains to the weighing device. This makes it possible to reduce the processing time on the receiving side and, consequently, the kernel processing time of the entire receiving apparatus.
