Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention is used in a cereal drying and preparing facility which can receive cereal from each producer and ship it through drying, selection and storage processes. The present invention also relates to an improvement of a system for voluntarily verifying the quality of the received grain, which is a system for voluntarily verifying grain samples.

(Prior Art) Conventionally, as a system of this type, while a received grain is being weighed by a receiving weighing machine, a sample collecting device collects a predetermined amount of a grain sample, and when the weighing is completed, the collected sample is dried. It is known that the sample is carried into each drying room of the machine by a sample carry-in / out device, and after drying is completed, the dried sample is carried out by the sample carry-in / out device to a voluntary testing device to perform a sample quality test.

(Problems to be Solved by the Invention) In this type of system, a sample loading / unloading operation must be performed by a single sample loading / unloading device for a sample dryer having a large number of drying chambers. For this reason, when there is frequent receiving grain, it is necessary to have the sample loading / unloading device preferentially carry out the work of loading the sample into the drying chamber. There was a problem that the work for the test could not be performed, and the work efficiency of the entire system was poor.

The present invention has been made in view of these points, and aims to solve the above problems.

(Means for Solving the Problems) In order to achieve the above object, the present invention employs the following configuration.

That is, according to the present invention, a predetermined amount of a grain sample is collected by a sample collection device while a received grain is being weighed by a receiving weighing machine, and when the weighing is completed, the collected sample is transferred into and out of each drying chamber of the sample dryer. After the drying, the dried sample is carried out to the voluntary testing device by the sample loading / unloading device after the drying is completed. A weighing end signal output unit that outputs a weighing end signal, a loading operation instruction unit that receives the weighing end signal, and instructs the sample loading / unloading device to load the sample into the drying chamber based on the weighing end signal; The presence or absence of a weighing end signal is detected, and when the signal is not output for a predetermined time, the sample carrying-in / out device has been dried. And unloading operation instruction means for instructing an operation for unloading voluntary test device from the drying chamber sample is made comprises a.

(Operation) In the present invention configured as described above, the loading operation instructing means receives the weighing end signal, and sends the sample to the sample loading / unloading device 3 based on this signal.
The operation to carry into the drying room is instructed. Thus, the sample loading / unloading device 3 performs a sample loading operation.

The unloading operation instructing means detects the presence or absence of the weighing end signal, and when the signal is not output for a predetermined time, it is regarded as a time interval for loading the sample into the drying chamber of the sample dryer 4 to be preferentially performed, and Instruct the carry-in / out device 3 to carry out the operation of carrying out the dried sample from the drying chamber to the voluntary verification device 5. Thereby, the sample carry-in / out device 3 carries out the work of carrying out the sample.

Therefore, in the present invention, although the sample carry-in work is normally performed with priority, when the weighing end signal is not over a predetermined time, it is regarded as a time interval of the sample carry-in work, and the sample carry-out work is performed using the time interval. Therefore, even with a single sample loading / unloading device, sample loading / unloading operations can be performed efficiently.

(Embodiment) FIG. 1 is a diagram showing an arrangement example of each device constituting a voluntary test system according to an embodiment of the present invention, and a flow of a sample.

In the figure, reference numeral 1 denotes a receiving weighing machine for measuring the weight of grain received in a grain drying preparation facility, for example, in units of 200 kg. Outputs end signal S1.

Reference numeral 2 denotes a sample collecting device attached to the receiving and weighing machine 1, and while the weighing machine 1 is weighing the receiving cereal, a part of the cereal is sampled as a sample particle for voluntary verification.

Reference numeral 3 denotes a sample loading / unloading device, and a sample collecting device 2
Receives the collected sample, the sample is carried into a drying chamber (not shown) of the sample dryer 4, and the dried sample is carried out from the drying chamber to the voluntary testing device 5 as described later.

The sample dryer 4 has a large number of drying chambers at the top, bottom, left and right, and dries a sample stored in each drying chamber to a target moisture value by hot air.

The voluntary testing device 5 sorts the sample into hulling and separates the sample into sized and immature grains, measures the weight of each of these grains, and performs a voluntary test based on the measurement result.

Reference numeral 6 denotes a sample packaging machine for packaging the sized and immature grains that have been subjected to the voluntary test by the voluntary testing device 5.

Next, a description will be given of a block diagram of an electric system of the independent verification system configured as described above.

Reference numeral 10 denotes an operation panel. Various switches such as a carry-in switch 10A for instructing a carry-in operation of the sample into the sample dryer 4 and a voluntary verification switch 10B for instructing carry-out of the dried sample from the sample dryer 4 and voluntary verification. Place the switch.

Reference numeral 11 denotes a control circuit composed of a microcomputer or the like. The control circuit 11 controls each unit as shown in the flowchart of FIG.

Next, a control example according to the present invention of the embodiment configured as described above will be described with reference to the flowchart of FIG.

Now, when the grain is carried into the grain drying and preparation facility, the receiving and weighing machine 1 receives the weighing signal S2 in FIG.
Perform the receiving weighing. The loading operation switch 10A and the self-verification switch 10B arranged on the operation panel 10
When turned on (step S1, step S2), the control described below is started.

First, the control circuit 11 detects whether or not the weighing end signal S1 indicating that the weighing of the received grain as shown in FIG. 4 has been completed has been output from the receiving and weighing machine 1 (step S3).

When the weighing end signal S1 is output, the control circuit 11
Outputs a carry-in operation signal S3 to the sample carry-in / out device 3 for performing an operation of carrying the sample taken by the sample taking device 2 into the drying chamber of the sample dryer 4. Thus, the sample loading / unloading device 3 performs a sample loading operation (step S4).

By the way, when the control circuit 11 receives the weighing end signal S1, a time t until the next weighing end signal S1 is received every time.
Is counted by the counting means. For example, when the time t reaches t = t1 as shown in FIG. 4, in other words, when there is no weighing end signal for a certain time (step S5), the control circuit 11 The carry-out operation signal S4 for carrying out the operation of carrying out the completed sample from the drying chamber of the sample dryer 4 to the voluntary verification device 5 is output to the sample carry-in / out device 3. Thereby, the sample loading / unloading device 3 performs a sample unloading operation (step S6).

The time t = t1 is longer than the time required for the sample carry-in / out device 3 to carry the sample into the drying chamber, for example, about 5 minutes.

By the way, when the sample loading device 3 receives the weighing end signal S1 while unloading the sample, the control circuit 11 gives priority to the unloading operation, and after the unloading operation is completed, outputs the loading operation signal S3 to thereby carry out the sample loading. The apparatus 3 shifts to a sample loading operation (see FIG. 4).

When both the carry-in operation switch 10A and the voluntary verification switch 10B are turned off, the above-described control operations are completed (steps S7 and S8).

(Effects of the Invention) As described above, in the present invention, the presence or absence of a weighing end signal is detected. By taking into account the interval, the dried sample is taken out of the drying room and self-assessment is performed by using this interval, so that loading and unloading work can be performed efficiently with a single sample loading and unloading device. The overall work efficiency can be improved.
