Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a device for providing a weight sensor for detecting weight on a hulling machine, a rice sorter, and a weighing machine, and calculating and displaying the work efficiency thereof. It is a thing.

(B) Conventional technology The conventional rice sorter only sorts the size of grain after hulling, and the weighing machine weighs the grain and closes the shutter when the set weight is reached, and then the bags It was structured so that it could be packed.

Further, as disclosed in Japanese Utility Model Laid-Open No. 61-46418, the structure for detecting the flow rate of grain is known in the grain huller, but the work efficiency is not displayed.

(C) Problems to be solved by the invention The work efficiency of the rice sorter and weighing machine is the weight of the grain flowing per hour, and the work efficiency is shown in the specification display of the huller and rice sorter. And the ability of the machine can be objectively determined. However, as in the past, it is not possible to rely on experience whether the ability of the huller or the rice sorter is fully utilized by displaying only the weight or the flow rate and displaying it. In addition, it is not clear at a glance when the work will end, and whether the flow rate matches the capacity of the huller and the rice sorter. I didn't know until I finished the work and looked at the results.

(D) Means for Solving the Problems In view of such a point, the present invention is configured as follows so that the work efficiency can be seen at a glance.

In the rice selection and weighing machine, a limit switch 16 that detects the opening and closing of the Glen sensor 14 and the shutter 15 is provided at the discharge port 13a of the Glen tank 13, and the weight increase amount when the grain is flowing smoothly is calculated. The work efficiency is calculated and the work efficiency is displayed.

(E) Embodiment The object of the present invention is as described above, and the structure of the present invention will be described based on the structure of the embodiment shown in the accompanying drawings.

FIG. 1 is a perspective view of a rice hulling machine connected to a rice selection and weighing machine. Second
The figure is a perspective view of rice selection and weighing machine. FIG. 3 is a partial cross-sectional view of the same side view. FIG. 4 is a front view showing the display panel section. FIG. 5 is a control block diagram. FIG. 6 is a control flowchart.

The overall structure will be described with reference to FIG. 1 and FIG.
The discharge part 2a of the paddy transporter 2 is attached to the sticking hopper 1 of the paddy, and the paddy is conveyed from the dryer or the paddy to the sticking hopper 1 and drops downward from the sticking hopper 1 to the rubber roll in the removing chamber 4. The rice husks were removed at
Further, the mixed rice is discharged to the outside of the machine, and the mixed rice is sorted by the sorting device 5, and the refined grains are selected from the elevator 6 by the guide pipe 7 and fed into the hopper 10 of the weighing machine A.

The rice selection and weighing machine A selects good rice (brown rice) and immature rice by a vertical selection spiral and a selection net in a selection device 11, immature rice is discharged from a chute 12, and good rice is fried in a grain tank 13. Is done. The Glen tank 13, as shown in FIG.
A grain sensor 14 is provided in the lower part of the grain tank 13 near the outlet 13a to detect whether or not brown rice is accumulated in the grain tank 13.

A shutter 15 is provided at the discharge port 13a at the lower end of the Glen tank 13, and the shutter can be stored in the Glen tank 13 when it is closed. The brown rice in the Glen tank 13 can be discharged. A limit switch 16 for detecting the opening of the shutter 15 is provided on the side surface of the sorting device 11 on the shutter opening side. 17 is a lever for opening and closing manually,
18 is a cover for preventing brown rice from scattering at the time of discharging.

A weighing machine 20 is arranged in front of the sorting device 11 below the discharge port 13a, and the weighing machine 2 has a built-in weight sensor 33. Is displayed. However, although a vertical type rice sorter is shown in the present embodiment, a horizontal type rice sorter may be used and a weighing machine may be arranged below the outlet.

A load cell or the like is used as the weight sensor, and calculation of weight, work efficiency, etc. is calculated by the controller 19 incorporated in the display panel 21.

The structure of the display panel 21, as shown in FIG. 4, is a weight display 22 and a work efficiency display 23 which are digitally displayed by a 7-segment LED, a setting dial 24 for setting the weight to be weighed, a setting display button 25, and a fine adjustment increment button. 26, a fine adjustment weight loss button 27, a zero setting button 28 for subtracting non-brown rice such as rice bags during weighing, and a conversion button 29 for converting and displaying work efficiency in the number of bags. However, it is possible to provide a changeover switch to display the work efficiency only by the weight display 22, and it is also possible to display it for a certain period of time using a timer.

As shown in FIG. 5, the controller 19 is composed of an A / D conversion circuit 30, an arithmetic circuit 31, and a drive circuit 32. A weight sensor 33 is connected to the A / D conversion circuit 30 and the arithmetic circuit 31 has a weighing function. Setting dial 24, setting display button 25, fine adjustment increase button 26, fine adjustment decrease button 27, zero setting button 28, conversion button 29, Glen sensor 14 and limit switch 16
Are connected in series, and are displayed on the work efficiency display 23 when both the Glen sensor 14 and the limit switch 16 are OFF. Then, the weight display 22 and the work efficiency display 23 are provided on the drive circuit 32.
Are connected.

(F) Action of the invention In such a configuration, the action of the present invention is shown in FIGS.
Explaining with the figure, first, before weighing, put a rice bag in the weighing machine 20.
Put 35 and press the zero setting button 28 to set zero,
Next, the amount to be weighed is set by turning the setting dial 24, and the amount is displayed on the weight display 22.

Next, press the setting display button 25 to change to the current weight, and the brown rice put into the Glen tank 13 from the sorting device 11 is placed on the weighing machine 20 from the outlet 13a and enters the rice bag 35, and its weight is Displayed on the weight display 22. At this time, brown rice is not accumulated on the Glen sensor 14, and since the shutter 15 is open, both the Glen sensor 14 and the limit switch 16 are turned off, weight sampling is performed, and the value at that time is set to W1, The set time T of the timer is read, and after a certain time T has elapsed, weight sampling is performed and the value is set as W2. When W2-W1 is divided by T, the work amount per unit time can be calculated, and the work efficiency H is calculated. This H is recorded in the memory as H1 and displayed on the work efficiency display 23.

When the amount of brown rice reaches the set amount, the shutter 15 is closed, the limit switch 16 is turned on, and the grain sensor 14
Brown rice accumulates on the top and turns on. Then, the weight sampling is stopped and the memorized H1 continues to be displayed.

When the rice bag 35 is changed and the lever 17 is opened, the limit switch 16 is turned off, but since there is brown rice on the grain sensor 14 for a while, weight sampling is not performed and both the grain sensor 14 and the limit switch 16 are turned off. Only then will weight sampling be performed.

By pressing the conversion button 29, the H1 can also display the work efficiency converted into the amount of paddy bag per hour. Conversely, it is also possible to predict the harvest amount of brown rice calculated from the amount of dried paddy, input the amount, subtract the amount of rice bags at the present time, and display the end time of the work.

(G) Effects of the Invention With the above-described structure and operation, the present invention has the following effects.

First, since the measured weight and work efficiency are displayed at the same time,
By comparing the hulling amount of the hulling machine with the capacity limit of the sorting amount of the sorting machine, it is possible to prevent unreasonable operation, and it is possible to adjust in a well-balanced manner.

Secondly, it becomes possible to easily estimate the work completion time from the remaining amount of paddy while checking the measured weight.
It became easier to make work plans.
