[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rice milling equipment for whitening brown rice into white rice.
[0002]
[Prior art]
As a rice milling treatment facility disposed at a store, a case where a measuring device for brown rice to be polished and a rice mill for polishing white rice to white rice are generally provided separately. And when selling over-the-counter, put the brown rice in the showcase etc. into the input hopper of the weighing device, weigh the brown rice with the weighing device and adjust it to the weight that the customer wants, and then weigh this A person brings the finished brown rice to the supply port of the rice mill and put it into operation.
[0003]
In addition, as a system combining a weighing device and a rice mill, a weighing device and a rice milling machine are arranged on both sides of the lifting device, and the brown rice weighed by the weighing device is conveyed upward by the lifting device to supply the rice milling machine There is also a rice mill that uses this milled rice to mill rice.
[0004]
For example, the rice mill 10 is configured as shown in FIG. A feed roll 2 and a whitening roll 3 are disposed inside the whitening chamber 1 connected to the supply hopper 9 on the side of the supply port 1a, which is the inlet, and a passage is provided at the outlet of the whitening chamber 1 in the closing direction. A resistance plate 4 is provided as load adjusting means for adjusting the load of the raw material (brown rice) in the milling chamber 1 by urgently limiting. In the milling process, the feed roll 2 and the milling roll 3 are rotationally driven by a driving motor 5 as a power source, and brown rice 6 as a milling raw material fed by its own weight from a supply hopper 9 is fed by the feed roll 2 to a resistance plate 4. The brown rice 6 is milled between the net 8 inside the milling chamber 1 and the milling roll 3 that is rotationally driven, and the milled rice is resisted against the resistance plate 4 from the white rice outlet 7. It comes to pay out.
[0005]
In addition, 11 is a tension spring that pulls the resistance plate 4, 12 is an adjustment motor that adjusts the urging force, 13 is a current sensor connected to the drive motor 5, 14 is a control unit that controls the rice mill, and 15 is various settings. A storage unit for storing data and the like.
[0006]
If the brown rice 6 supplied from the supply hopper 9 is exhausted after the rice milling process is finished, the brown rice 6 is not pushed into the milling chamber 1, the torque applied to the milling roll 3 is reduced, and the current amount of the drive motor 5 is increased. Therefore, when the current sensor 13 detects that the current amount of the driving motor 5 has decreased, the control unit 14 determines that the rice milling process has ended and stops the rice milling operation.
[0007]
[Problems to be solved by the invention]
However, in a rice mill processing facility in which a weighing device and a rice milling machine are provided separately, it is time-consuming because it is necessary for a person to carry and transfer the brown rice weighed by the weighing device to the rice milling machine. On the other hand, there is a problem that a large installation area is required because a lifting device is provided in addition to the weighing device and the rice milling machine in the rice milling facility that transports the brown rice measured by the weighing device to the rice milling machine using the lifting device. In particular, this rice milling facility may be placed at the store, which may cause trouble.
[0008]
In addition, there is also a problem that these rice milling facilities cannot confirm or manage the progress of the rice milling process. In other words, when the weighing device is provided with a display unit, the weight of the brown rice thrown into the feeding hopper can be checked to confirm whether the brown rice has disappeared in the weighing device. It was not possible to confirm whether the rice had been transported to the rice mill, so the actual amount of brown rice reaching the rice mill could not be confirmed.
[0009]
The present invention solves the above-mentioned problems and problems, and not only does a person carry brown rice to a rice mill and requires a large installation area, but also easily confirms the progress of the rice milling process. The purpose is to provide rice milling equipment that can be used.
[0010]
[Means for Solving the Problems]
In order to solve the above problems, the present invention is a rice milling facility that performs rice milling processing by passing brown rice through a rice milling machine only once, and brown rice that has not yet been milled is introduced to remove the brown rice from the outlet. A charging hopper for discharging, a gate means for opening and closing a discharging port of the charging hopper, a weighing means for measuring the weight of brown rice that has not yet been polished in the charging hopper, and a rice mill, comprising these charging hopper and gate And a weighing unit comprising weighing means and a weighing means are directly connected to the upper portion of the rice mill and configured to supply brown rice discharged from the discharge port of the input hopper directly to the supply port of the rice mill. and detecting a reduction state of the weight of the rice in the inner by metering means, configured to gate means is closed and weighed to a predetermined weight fraction of brown rice is reduced in projecting input hopper, the hopper A flow path switching means is provided at the downstream side until reaching the supply port of the rice milling machine so that the brown rice discharged from the discharge port of the input hopper can be switched to the extraction storage unit that can be extracted to the outside. It is a thing.
[0011]
With this configuration, the weighing unit is arranged directly above the rice mill, and the brown rice discharged from the discharge port of the input hopper is directly supplied to the supply port of the rice mill. Saves time and effort to transport to the machine, requires less installation area, and further reduces the amount of brown rice in the weighing means equal to the amount supplied by the milling machine, so the weighing data from the weighing means is input to the control means, etc. Thus, the state of supply to the rice milling machine can be taken in by the rice milling machine itself, and used for controlling the rice milling machine such as the determination of the rice milling end time.
[0012]
In addition, by providing a display unit that displays the weight of the brown rice in the charging hopper, a person can easily check the progress of the rice milling process.
In addition, if you want to mill only a certain weight of brown rice by storing the brown rice from the loading hopper on the downstream side of the loading hopper and providing a flow path to the storage unit for taking out this brown rice to the outside, When the brown rice in the hopper is reduced by a predetermined weight, the gate means can be closed manually or automatically, and then the remaining brown rice can be discharged via the flow path to the storage for storage. It is.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. Since the structure of the rice milling machine is the same as the conventional one, its description is omitted, and the same function is given the same symbol.
[0014]
As shown in FIG. 1, in this rice milling equipment, a weighing unit 20 is disposed above the rice milling machine 10.
The weighing unit 20 includes a loading hopper 21 into which the brown rice 6 is charged and discharges the brown rice 6 from the discharge port 21a, a support member 22 that supports the loading hopper 21, a gate 23 that opens and closes the discharge port 21a of the loading hopper 21, A load cell 24 as a weighing means for measuring the weight of the brown rice 6 in the charging hopper 21, a display unit 25 for displaying the weight of the brown rice 6 in the charging hopper 21, and a slanting lower part of the charging hopper 21 are provided. A flow path switching lever 26, a take-out storage section 27 for storing the brown rice 6 from the input hopper 21 via the take-out flow path 27a, a control section 28 for controlling both the weighing unit 20 and the rice mill 10; An operation unit 29 having a start button and input keys for inputting various data, and a storage unit 30 storing information necessary for the weighing operation and the rice milling operation are provided. A support member 22 that supports the charging hopper 21 is directly connected to the supply hopper 9 of the rice milling machine 10.
[0015]
In the above configuration, when the brown rice 6 is put into the charging hopper 21, the brown rice 6 is weighed based on the data output from the load cell 22, and this measured value is displayed on the display unit 28. Here, when the whole amount is to be polished, the start button of the operation unit 29 is pressed as it is, and when it is desired to polish a predetermined weight, the start button is pressed after inputting the weight from the operation unit 29. In the standby state, the gate 23 is closed and the flow path switching lever 26 is held in the posture shown by the solid line in FIG.
[0016]
When the start button is pressed, the gate 23 is opened and the brown rice 6 is supplied from the input hopper 21 to the supply hopper 9 of the rice milling machine 10, and the rice milling operation is sequentially performed. In this case, the opening degree of the gate 23 is adjusted so that an amount corresponding to the rice milling amount is supplied to the supply hopper 9. At the time when the rice milling process is being performed, the clock amount operation is performed and the remaining weight of the brown rice 6 in the input hopper 21 is displayed, so that the person can easily confirm the progress of the rice milling process. it can.
[0017]
If the rice is set to be polished by a predetermined weight, the gate 23 is temporarily closed when the brown rice 6 in the feeding hopper 21 is reduced by a predetermined weight, and the flow path switching lever 26 is shown by a virtual line in FIG. It is switched to the posture shown. Then, the gate 23 is opened again, and the remaining brown rice 6 is poured out into the take-out storage unit 27.
[0018]
When the brown rice 6 in the input hopper 21 is lost and this is detected by the weighing unit 20, or when the brown rice 6 of a predetermined weight is reduced and the gate 23 is closed, the supply of the brown rice 6 to the rice mill 10 is stopped. The control unit 28 is informed that the supply of the brown rice 6 has been completed, and it is detected that the signal has been input and the amount of current of the driving motor 5 (see FIG. 2) for driving the milling roll 3 has decreased. Then, the control unit 14 determines that the rice milling process has been completed and stops the rice milling operation. In this way, since the weighing unit 20 is directly connected to the rice milling machine 10, it is possible to detect the end of the supply of the brown rice 6 to the rice milling machine 1 without a time lag, and as a result, to detect the end timing of the rice milling operation. Judgment can be made more reliably.
[0019]
In addition, since the brown rice 6 from the weighing unit 20 is supplied to the rice mill 10 as it is, it is not necessary for a person to carry the brown rice 6 to the rice mill 10 and is almost the same as the case of using only the rice mill 10 or slightly. Since the rice milling equipment equipped with the weighing unit 20 can be installed in a wide area, it becomes space-saving and particularly suitable for installation in stores. Further, since there is almost no transport time from the weighing unit 20 to the rice mill 10, processing time from weighing to rice milling is also shortened.
[0020]
Further, as described above, it is possible to freely polish the rice by a predetermined weight, and it is also possible to polish the rice by a predetermined weight several times and sell it.
[0021]
In the above embodiment, when the rice milling end time is determined by detecting the end of the supply of the brown rice 6 based on the measured value and detecting that the current amount of the driving motor 5 has decreased. However, the present invention is not limited to this, and the rice milling end time may be determined from other conditions and measured values. Furthermore, the rice milling may be performed after a predetermined time from the end of the supply of the brown rice 6. The operation can also be terminated.
[0022]
【The invention's effect】
As described above, according to the present invention, the weighing unit is directly connected to the upper portion of the rice mill, and the brown rice discharged from the discharge port of the input hopper is directly supplied to the supply port of the rice mill. This saves time and effort for a person to carry brown rice to a rice mill and can be installed in a small installation area, making it space-saving and particularly suitable for installation in stores. Further, since there is almost no transport time from the weighing unit to the rice mill, the processing time from weighing to rice milling is shortened. Further, it is possible to freely polish the rice by a predetermined weight, and it is also possible to polish the rice by a predetermined weight several times and sell it. And since it can detect without the time lag that supply of the brown rice to the rice mill was completed, the end timing detection judgment of rice milling operation can also be performed more certainly.
