[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a continuous type rice milling apparatus that performs a rice milling process step by step by sequentially operating a plurality of rice milling machines.
[0002]
[Prior art]
Trying to polish rice with one rice mill at a time takes time, so it is not suitable for mass production. Also, if you first grind using a grinding-type rice milling machine, and then use a friction-type rice milling machine, you will not need to apply too much pressure, so the milling finish will be good and the flow rate will be increased. Efficiency. From such a background, conventionally, a plurality of rice milling machines have been used in an articulated manner.
[0003]
Such a rice milling process of the simultaneous type rice milling apparatus is executed as a series of processes according to a sequencer program programmed in advance.
[0004]
[Problems to be solved by the invention]
By the way, the timer in the sequencer program is set to a predetermined time at the time of shipment from the factory, but when actually used as a solid rice milling machine in the field, several timers are set depending on the varieties, moisture content of brown rice, etc. You may want to change In such a case, conventionally, a personal computer with dedicated software is operated by a person with specialized knowledge to change the timer setting, or using a dedicated machine called a loader. There was no choice but to change the timer setting by a person with expert knowledge. For this reason, the work of changing the setting of the timer in the field is troublesome, which is also a cause of lowering the work efficiency.
[0005]
In particular, if the conventional method is adopted in the joint-type rice milling device, an electric circuit using a timer and a relay must be assembled, resulting in an increase in the number of parts and an increase in the number of assembling steps. It was connected.
[0006]
In view of the above facts, the present invention has an object to obtain a continuous type rice milling apparatus which can improve the efficiency of rice milling work on site and can reduce the cost.
[0007]
[Means for Solving the Problems]
According to a first aspect of the present invention, the material for the rice milling process is supplied with the raw material input unit provided with the outlet opening / closing means on the discharge outlet side and discharged from the raw material input unit. A stage by sequentially operating a plurality of rice milling machines each comprising a tensioning section in which the raw material is stretched and a rice milling processing section that processes the raw material stretched from the tensioning section in sequence. In the continuous-type rice milling apparatus that performs the rice milling process, the plurality of rice mills are provided with operation panels for each of the rice mills , and each operation panel is started or stopped at a predetermined timing. Setting change operation means for changing the setting of a timer for measuring time is provided, and the setting change operation means detects whether or not the raw material that is provided in the stretching portion and is to be subjected to the rice milling process remains. Remaining amount detection hand Is used for changing the setting of a timer for measuring the time from when the state of no remaining amount is detected until the operation of the rice milling unit is stopped, and is provided in the raw material input unit provided in the rice milling machine of the next process After the full amount state is detected by the full amount detection means for detecting whether or not the input amount of the raw material is full, the full amount after the outlet opening / closing means provided in the rice milling machine of the previous process is closed. It is characterized in that it is used for changing the setting of a timer that measures the time from when the full amount detection state by the detection means is released until the outlet opening / closing means is again opened .
[0010]
According to the first aspect of the present invention , the rice milling process is performed in each rice mill as follows. First, a raw material to be subjected to a rice milling process is input to the raw material input unit. Since the outlet opening / closing means is provided on the discharge outlet side of the raw material charging portion, the raw material is stored when the outlet opening / closing means is closed, and the raw material is discharged when the outlet opening / closing means is open. When the outlet opening / closing means is opened and the raw material is discharged from the raw material charging unit, the raw material is stretched into the stretching unit and is subjected to the rice milling process in the rice milling unit.
Here, in the present invention, the plurality of rice mills constituting the simultaneous type rice milling apparatus are provided with operation panels for each of the rice milling machines, and each operation panel is provided with setting change operation means. By operating the setting change operation means from the outside, the timer setting can be easily changed for each rice mill. In other words, it is not necessary to use a dedicated machine for changing the timer setting, and it is not necessary to rely on a programming operation of a person with specialized knowledge.
[0011]
Furthermore, according to the present invention, since it is possible to eliminate an electric circuit using a timer and a relay that have been conventionally required, it is possible to reduce the number of parts and the number of assembling steps.
[0013]
Further, in the present invention, the remaining amount detecting means is provided in the stretching portion, and it is detected by this remaining amount detecting means whether or not the raw material to be polished is left in the stretching portion. When a predetermined time is measured by the timer after the state of no remaining amount is detected, the operation of the rice milling unit is stopped. In the present invention, the setting of this time, that is, the time until the operation of the rice milling unit is stopped after the remaining amount detecting unit detects the state of no remaining amount is changed by operating the setting changing operation unit. can do. Therefore, according to the present invention, it is possible to set an optimum time according to the varieties, the moisture value of brown rice, and the like.
[0014]
Furthermore, according to the present invention, when a full state is detected by the full amount detection means provided in the raw material input unit provided in the next process rice mill, the outlet opening / closing means of the raw material input unit provided in the previous process rice polishing machine Is closed. Thereafter, as the rice milling process in the next process proceeds, the raw material input to the raw material input unit decreases, and the full amount detection state by the full amount detection means is released. When the full amount detection state is canceled, the outlet opening / closing means of the rice milling machine in the previous process is opened again, and the rice milling process is performed in the rice milling unit. Thereby, it becomes possible to replenish the raw material (through the rice milling process by the rice milling machine in the previous process) to the material input part of the rice milling machine in the next process.
[0015]
Here, the time from when the full amount detection state by the full amount detection unit is released to when the exit opening / closing unit is opened again varies slightly depending on the varieties, the moisture value of the brown rice, and the like. In the present invention, the setting of the timer that measures this time can be quickly and easily changed by the operator on site using the setting change operation means. Therefore, in the present invention, it is possible to optimize the settings of the two types of timers.
[0016]

It corresponds to “change operation means”.
[0030]
Next, the operation and effect of this embodiment will be described.
[0031]
First, taking the first machine 12 as an example, an outline of the rice milling process of a single rice mill will be described. First, a raw material (brown rice G) to be subjected to the rice milling process is supplied to the raw material supply port 22 of the elevator 20. The supplied raw material is raised by a conveyor disposed in the elevator 20 and discharged from the raw material inlet 24. The discharged raw material is input as it is into the tank 26 in which the shutter 30 is closed. When the introduction of the raw material proceeds, the full amount detection sensor 32 detects the full state of the raw material in the tank 26. When the full state of the raw material is detected, the shutter 30 is opened, and the raw material stored in the tank 26 is put into the hopper 36. The raw material stretched into the hopper 36 is sent to the rice milling unit 34 and subjected to a predetermined rice milling process. The raw material after the rice milling process is discharged from the discharge port 40 provided on the lower side surface of the rice milling unit 34 and supplied to the raw material supply port 22 of the elevator 20 of the second machine 14 which is the next process. Thereafter, the rice milling process proceeds step by step in the order of No. 2 machine 14 and No. 3 machine 16, and finally, the polished rice H is discharged from the discharge port 40 of the rice milling section 34 of No. 3 machine 16.
[0032]
Here, when the joint-type rice milling apparatus 10 is actually used in the field, there is a case where it is desired to change the setting of the timer at the time of factory shipment due to the varieties, the moisture value of brown rice, or the like. In such a case, in the present embodiment, the timer setting can be changed as follows.
[0033]
First, the operation of the rice milling unit 34 is stopped (M1 is turned off) after the remaining amount detection sensor 38 provided in the hopper 36 detects the state of no remaining amount (m1 is turned off in the case of the first machine 12 as an example). When changing the setting of the timer for measuring the time until the start, as shown in FIG. 3, first, the stop switch 48 and the shutter close switch 54 of the operation panel 42 are simultaneously set to a predetermined time (for example, 3 seconds in this embodiment). Press above. Then, the lamp of the operation switch 46 blinks and the current timer value (second) is displayed on the flow rate digital display window 52 (the factory setting is 5 seconds as an example). Next, the flow rate adjustment knob 50 is twisted to change the timer value to a desired value. If the timer value is made smaller than the factory setting, the operation of the rice milling unit 34 is stopped earlier. Conversely, if the timer value is made larger than the factory setting, the rice milling unit 34 is stopped. The operation of is stopped so late. Note that the above timer setting change operation can be performed independently for each of the first machine 12, the second machine 14, and the third machine 16 that make up the tandem rice milling apparatus 10.
[0034]
Next, the full state of the raw material is detected (t2 is turned on) by the full amount detection sensor 32 disposed in the tank 26 (T2) provided in the rice milling machine of the next process (for example, No. 2 machine 14). After the shutter 30 (S1) of the 12 tanks 26 (T1) is closed, it is detected that the full state of the raw material has been released by the full amount detection sensor 32 (t2 off). When changing the setting of a timer for measuring the time until the shutter 30 (S1) is opened again, as shown in FIG. 4, first, the stop switch 48 and the shutter close switch 54 of the operation panel 42 are simultaneously turned on for a predetermined time. (For example, in this embodiment, 5 seconds or more). Then, the lamp of the shutter opening switch 56 blinks and the current timer value (second) is displayed on the flow rate digital display window 52 (the factory setting is 10 seconds as an example). Next, the flow rate adjustment knob 50 is twisted to change the timer value to a desired value. If the value of the timer value is made smaller than the factory default setting, the shutter 30 (S1) opening operation of the first machine 12 will be faster as soon as the raw material in the tank 26 (T2) of the second machine 14 is not full. On the contrary, if the value of the timer value is made larger than the factory default setting, the shutter 30 (S1) is opened more slowly. Note that the above timer setting change operation can be performed independently for each of the first machine 12, the second machine 14, and the third machine 16 that make up the tandem rice milling apparatus 10. Further, the above timer setting change operation is an operation unique to the simultaneous rice milling apparatus 10.
[0035]
When confirming the changed setting and returning it to the rice milling posture, as shown in FIG. 5, press the stop switch 48 and the shutter close switch 54 simultaneously for a predetermined time (in this embodiment, for example, 7 seconds or more). That's fine.
[0036]
As described above, in the continuous type rice milling apparatus 10 according to the present embodiment, the operation panel 42 is provided in each of the first machine 12 to the third machine 16 constituting the continuous seating type rice milling apparatus 10, and the stop switch 48, the shutter of the operation panel 42 is provided. When the operator at the site uses the closing switch 54 and the flow rate adjusting knob 50 to perform a predetermined operation from the outside, the timer setting can be easily changed for each rice mill. In other words, it is not necessary to use a dedicated machine for changing the timer setting, and it is not necessary to rely on a programming operation of a person with specialized knowledge. As a result, it is possible to improve the rice milling work efficiency at the site.
[0037]
Further, in the continuous-type rice milling apparatus 10 according to the present embodiment, an electric circuit using a timer and a relay, which is required in the case of the conventional system of the continuous type, can be eliminated, so that the number of parts can be reduced and assembled. Man-hours can be reduced. As a result, cost reduction can be achieved.
[0038]
In particular, in the present embodiment, the setting of the timer from when the remaining amount detection sensor 38 detects that there is no remaining amount to when the operation of the rice processing unit 34 is stopped can be changed using the operation panel 42. Therefore, it is possible to set the optimum time according to the varieties and the moisture value of the brown rice. As a result, it is possible to quickly perform the rice milling process with high accuracy for each state of varieties and brown rice.
[0039]
In addition, in the present embodiment, the setting of the timer from when the full detection state by the full detection sensor 32 is released until the shutter 30 is opened again can be changed using the operation panel 42. Two types of timer settings can be optimized. As a result, the optimization of the time setting according to the varieties, the moisture value of brown rice, etc. can be made even more accurate.
[0040]
Further, in the present embodiment, since the timer setting change described above can be performed by simultaneously pressing the stop switch 48 and the shutter close switch 54, it is not necessary to newly install a switch for changing the timer setting. . Therefore, the number of types of switches can be reduced, and the complexity of the structure of the operation panel 42 can be avoided.
[0041]
In the above-described continuous-type rice milling apparatus 10 according to this embodiment, the apparatus is configured as a three-unit continuous-type, but it is arbitrary how many rice milling machines are to be in series. Also, at that time, what kind of rice milling machine should be used, that is, whether the rice milling should be performed using only the friction-type rice milling machine, or after roughing the brown rice with the grinding-type rice milling machine, one or more Whether or not to finish using a friction-type rice milling machine can be arbitrarily selected according to the varieties, moisture content of brown rice, and the like.
[0042]
Further, in the above-described joint-type rice milling apparatus 10 according to the present embodiment, the timer setting is changed using the stop switch 48, the shutter close switch 54, and the flow rate adjustment knob 50 of the operation panel 42. Not limited to this, a configuration in which the timer setting is changed using another switch may be adopted.
[0043]
Furthermore, although the example which changes the setting of two types of timers was shown in the joint type rice milling apparatus 10 which concerns on this embodiment mentioned above, this invention is applied in order to change the setting of not only this but another timer. May be.
[0044]
