Description

The present invention relates to a grain processing facility with a test dryer sample loading device.

In a grain processing facility such as a grain dry preparation storage facility, a portion of incoming grain is extracted as sample grain and supplied to an independent assay device. The self-verification device performs weighing, dehusking, sorting, etc. of the grain, and calculates the yield from the weighing data of the granules and scrap grains. Sample grains are dried in a test dryer before being fed into such self-testing equipment.

As ancillary equipment for such a test dryer, Patent Document 1 discloses a device for automatically carrying sample grains into the test dryer without relying on human intervention. According to Patent Document 1, a plurality of sample carrying means are provided corresponding to the number of test dryers, and a carrying means for carrying the sample grain toward each sample carrying means is provided. A technical measure is taken to provide a transfer direction switching means for switching the transfer direction of the sample grain. Then, every time the drying chamber provided in the test dryer becomes full, the conveying direction switching means is operated to switch the conveying direction, and drying is started in a full state so as not to create an empty space in the drying chamber of the test dryer. Do.

That is, rotate the belt conveyor (or switching valve) in the forward direction (or switch the switching valve to one direction) to receive sample grains in each drying chamber of the first test dryer, then When each drying chamber of the test dryer is full, the belt conveyor (or switching valve) is rotated in the opposite direction (or the switching valve is switched in the other direction) to load the sample grain into each drying chamber of the second test dryer. , and even if a plurality of first and second test dryers are installed, the loading can be automated, and the burden on the operator can be eliminated.

However, since the above-mentioned conventional carrying-in device can only be switched in two directions, it is suitable for mass processing by installing a plurality of test dryers such as the first, second, and third test dryers. I couldn't do it.

Overall operations of the test dryer 10 , the self-test device 11 and the sample loading device 15 are controlled by the control device 130 . The control device 130 is a personal computer in which a predetermined program is installed in this embodiment. The control device 130 also functions as a monitoring unit 131 and a management unit 132 by executing installed programs. The monitoring unit 131 monitors each of the plurality of sample boxes in the test dryer 10 to see if the drying of the samples contained in the sample box is completed. The management unit 132 controls whether or not a new sample can be loaded into the test dryer 10 by controlling the sample loading means 15 based on the monitoring status of the monitoring unit 131 .

FIG. 6 is a diagram exemplifying the monitoring status by the monitoring unit 131. As illustrated in FIG. In this embodiment, the monitoring unit 131 monitors each of the plurality of test dryers 10 by classifying them into "drying", "waiting for discharge", and "discharging". "Drying" indicates that the sample is being dried. "Waiting for discharge" indicates a state in which the drying of the sample has been completed, but the sample is still stored in the test dryer. “Discharging” indicates that the sample is taken out from the test dryer 10 and is in the process of being transferred to the self-test device 11 .

Basic operations of the test dryer 10, the self-test device 11, the sample loading device 15, and the control device 130 will be described.

When the control device 130 receives a signal indicating that the weighing of the sample has been completed by the receiving weighing machine 13 (see FIG. 1), the control device 130 receives the signal from the monitoring unit 131 and the management unit 132, and the plurality of test dryers installed. Of the 10, the address of which drying chamber of which test dryer 10 is available can be searched for.

Next, the control device 130 issues a command to the sample loading device 15 to load the sample into the test dryers 10 extracted by the above search. In other words, a signal is sent to the actuator 39 installed in the drying line switching means 20, the channel aggregation means 25, and the test dryer distribution means 21 serving as the sample carry-in device 15, and the channel is switched.

For example, it is assumed that a sample received by the A-series receiving and weighing machine 13a is carried into the A-series test dryer 10a-2. The sample is transferred from the receiving weighing machine 13a to the receiver tank 17a via the sample extractor 14a, the pneumatic conveying ejector 16a, and the conveying pipe 18. As shown in FIG.
Therefore, switching of the drying line switching means 20a, the channel consolidation means 25b, and the test dryer distribution means 21b is performed. The drying line switching means 20a selects the intersecting flow path 24a, the flow path combining means 25b selects the flow path 26b, and the test dryer distribution means 21b selects the flow path 27a-2.

Then, when the control device 130 receives a signal indicating that the channel has been switched from the sample loading device 15, the control device outputs a drive signal to the fan installed in the test dryer 10a-2. Thereby, the sample stored in the receiver tank 17a is pneumatically transported to the specific test dryer 10a-2.

According to the sample carrying-in device of the test dryer described above, even if the number of receiving trains and the number of receiving hoppers are designed to be plural depending on the processing capacity of the facility, it is possible to respond appropriately. For example, when the receiving process is formed with multiple lines and multiple hoppers in consideration of receiving peaks and user convenience, it is possible to carry in a specific single test dryer. In addition, when the goods receiving process is formed in one line and in a single hopper, it becomes possible to carry in a plurality of test dryers. In addition, when multiple trains and multiple hoppers are used for the receiving process, and multiple trains and multiple test dryers are installed in accordance with the trains of the receiving process, the control device specifies which test dryer to load into. Therefore, the sample can be smoothly carried into the test dryer, and therefore the waiting time for sample carry-in can be reduced.

Although several embodiments of the present invention have been described above, the above-described embodiments of the present invention are intended to facilitate understanding of the present invention, and do not limit the present invention. The present invention may be modified and improved without departing from its spirit, and the present invention includes equivalents thereof. In addition, within the range where at least part of the above problems can be solved or where at least part of the effect is achieved, the components described in the claims and the specification can be combined or omitted. .
