Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a coin-polishing device that operates in response to a coin that has been inserted to process rice grains such as brown rice into white rice.

[Prior Art] There is known a coin-polishing device that operates according to a coin that is inserted and that processes an inserted rice grain (brown rice) into white rice.

In the conventional coin rice polishing apparatus, a rice polishing machine provided with a whitening roll is arranged inside the machine body. Further, a stake hopper into which rice grains are introduced is provided on the front wall of the machine body, and the stake hopper is connected to the rice milling machine via a carrier device such as an elevator. Further, a coin insertion portion and a driving switch are provided on the front wall of the machine body so that coins can be inserted and the coin-polishing device can be operated according to the inserted coins.

When using this coin-polishing device, put rice grains into the tensioning hopper, insert a predetermined number of coins into the coin insertion part, then operate the operating switch, and the introduced rice grains will be conveyed by the elevator or the like. It is supplied to the rice mill, and the whitening roll of the rice mill is rotated to process the rice and remove it as white rice.

As described above, the conventional coin rice polishing apparatus can automatically polish rice according to the inserted coin to make white rice.

[Problems to be solved by the invention] However, in the conventional coin rice polishing apparatus, when a predetermined number of coins are inserted into the coin insertion portion when the apparatus is operated, it is determined whether or not the rice grains are inserted into the stake-in hopper. Regardless of this, the device is operated by the operation of the operation switch, the whitening roll of the rice mill starts to rotate, and the timer for measuring the device operation time is started.

For this reason, if a user who is unfamiliar with the operation of the device accidentally inserts a coin before operating the rice switch and operates the operation switch,
There was a drawback that the milling roll idled and the residual rice in the rice polishing machine was roughened and cracked, and after the rice grains were properly added, the damaged rice was sequentially taken out of the machine and mixed. In addition, if a rice grain is thrown into the hopper with a long delay after inserting a coin and operating the operation switch, the above-mentioned timer is started at the same time when the operation switch is operated and the whitening roll is rotated, so that the time is set within a preset time. However, the processing of all the introduced rice grains was not completed, and untreated rice grains remained in the swelling hopper.

In view of the above facts, the present invention has an object to obtain a coin rice polishing apparatus capable of preventing erroneous operations and performing rice polishing processing without waste and surely to produce white rice.

[Means for Solving the Problems] A coin rice polishing apparatus of the invention according to claim (1) is a rice hopper that is provided on a side wall of a machine body and into which rice grains are put, and a rice grain that is received in the rice hopper and receives rice grains. A rice polishing section for processing and a coin insertion section for inserting a predetermined number of coins are provided, and the rice polishing section is driven for a predetermined time in accordance with the coins inserted into the coin insertion section and is inserted into the tension hopper. A coin rice polishing apparatus for processing rice grains into white rice, the rice grain detecting means being arranged in the swelling hopper and detecting the presence of the introduced rice grains, and being able to return the coins placed in the coin slot. It is characterized in that it is provided with a coin returning means and a control means for putting the coin returning means into a coin non-returning state only when the rice grain detecting means detects a rice grain.

[Operation] In the coin rice polishing apparatus according to claim (1), when the rice grain is thrown into the swelling hopper, this is detected by the rice grain detecting means, and only in this case, the coin returning means is in the coin non-returning state by the control means. Becomes That is, in other words, coins cannot be practically inserted unless rice grains are inserted into the stakeout hopper.

Therefore, even if a user who is unfamiliar with the operation of the device mistakenly inserts a coin before inserting rice grains, the coin is not returned and the device does not operate, and an erroneous operation is prevented. Further, in this case, since the inserted coin does not remain in the device, it does not cause a failure.

Further, a coin insertion portion 26 is provided on the front wall of the machine body 12 so that a predetermined number of coins 30 can be inserted. A coin sensor 32 is arranged in the coin insertion portion 26, and the inserted coin 30 can be detected. The coin sensor 32 is connected to a control circuit 36 described later.

An operation switch 28 is provided below the coin slot 26 and is also connected to the control circuit 36.

A rice grain sensor 34 as a rice grain detecting means is provided at the bottom of the tensioning hopper 14 and can detect the introduced rice grain. The rice grain sensor 34 is generally of the mechanical limit switch type, but may be of any other type such as a pressure type or a type using an optical sensor. The rice grain sensor 34 is also connected to the control circuit 36.

The structure of the control circuit 36 is shown in FIG. Rice mill
The whitening roll driving motor 38 of 22 is connected to a power source via a starting contact 40.

In addition, the power source is the operation switch 28 and the relay coil 42.
Are connected in series. Relay contact on the operating switch 28
42A is connected in parallel. The relay contact 42A is a self-holding circuit of the operation switch 28, and when the operation switch 28 is activated and the relay coil 42 is excited, the relay contact 42A is closed.

Further, a coin sensor switch 44 operated by the coin sensor 32 and a relay coil 46 are connected in series to the power source. A relay contact 46A is connected in parallel to the coin sensor switch 44. The relay contact 46A is a self-holding circuit for the coin sensor switch 44.
When 44 operates and relay coil 46 is excited, relay contact 46
A is closed.

A rice grain sensor switch 48 and a relay coil 50 which are operated by the rice grain sensor 34 are connected in series to the power source.

Further, the power supply includes a relay contact 42B that is closed by exciting the relay coil 42, a relay contact 46B that is closed by exciting the relay coil 46, a relay contact 50B that is closed by exciting the relay coil 50, and a motor for closing the start contact 40. A relay coil 52, a delay timer 54, and a relay contact 54A opened by the delay timer 54 are connected in series.

 Next, the operation of this embodiment will be described.

When using the coin-polishing device 10 having the above-mentioned configuration, the paddy rice M or brown rice G is put into the swelling hopper 14 and
A predetermined coin 30 is inserted into the coin insertion portion 26. Further, when the operation switch 28 is operated, the coin hulling and rice polishing device 10 is operated for a predetermined time according to the inserted coin 30.

That is, when the paddy rice M or the brown rice G is put into the swelling hopper 14, this is detected by the rice grain sensor 34, the rice grain sensor switch 48 is activated, and the relay coil 50 is closed.
Is excited. Therefore, the relay contact 50B is closed.
When a coin 30 is inserted into the coin slot 26, the coin sensor 32 detects this and the coin sensor switch 44 is closed, and the relay coil 46 is excited and at the same time the relay contact 46A, which is a self-holding circuit, is closed and relayed. Coil 46
Excitation is maintained. Therefore, the relay contact 46B is closed. Further, when the operation switch 28 is operated, the relay coil 42 is excited, and at the same time, the relay contact 42A which is a self-holding circuit is closed to keep the excitation of the relay coil 42.
Therefore, the relay contact 42B is closed.

When the relay contacts 42B, 46B, 50B are closed, the motor relay coil 52 is excited, whereby the start contact 40 is closed and the whitening roll drive motor 38 is driven to drive the rice polishing machine.
22 starts driving. At the same time, the delay timer
54 starts.

Here, regardless of whether the rice grain that has been put into the hopper 14 by the user is paddy rice M or brown rice G, the put-in rice grain is lifted and conveyed by the elevator 16 and supplied to the grain huller 18 to be removed. It is processed.

In this case, the rice grains put into the squeeze hopper 14 are paddy rice M.
In that case, after removing the rice and making it as brown rice G,
It is supplied to the stone removing machine 20 from 18 outlets 18A. Stone removing machine 2
At 0, the pebbles S mixed in the brown rice G are separated, and only the brown rice G is sent to the rice polishing machine 22. The brown rice G sent to the rice-polishing machine 22 is subjected to rice-polishing treatment to be white rice H, and then the discharge port 22A.
And is accumulated in the accumulation tank 24.

On the other hand, even when the grain of rice fed into the tensioning hopper 14 is brown rice G, it passes through the grain huller 18 and is further destoner 20.
After that, it is sent to the rice mill 22. Where the huller
The brown rice G that has passed through 18 is slightly rubbed on the surface by the grain huller 18 to be in a slightly roughened state. Therefore, when the rice milling machine 22 is subsequently subjected to rice milling, the coefficient of friction is increased and the rice milling is efficiently performed. In this case as well, after the rice polishing treatment, it becomes white rice H and is taken out from the discharge port 22A and accumulated in the accumulation tank 24.

After the completion of the rice polishing process, that is, after the elapse of the set time of the delay timer 54 set according to the inserted coin 30, the relay contact 54A is opened. Therefore, the motor relay coil 52 is demagnetized to open the starting contact 40, the whitening roll drive motor 38 is stopped, and the rice mill 22 ends its operation.

In this way, when rice grains are fed into the tensioning hopper 14, this is detected by the rice grain sensor 34, and only in this case, the rice mill 22 can be driven. That is, the rice milling machine 22 is not driven unless rice grains are put into the tensioning hopper 14.

Therefore, even if a user who is unfamiliar with the operation of the device mistakenly inserts the coin 30 and operates the operation switch 28 before inserting the rice grains, the rice mill 22 does not idle, and the residual rice has rough skin and cracks. It does not occur and damaged rice is not mixed in. In addition, even if the rice 30 is thrown into the hopper 14 with a long delay after the coin 30 is thrown and the operation switch 28 is operated, the rice milling machine 22 starts to drive only after the rice is thrown in, so that the rice milling machine 22 is operated within a preset time. The processing of all rice grains can be completed, and no untreated rice grains remain in the swelling hopper 14.

In this way, erroneous operation of the device is prevented, and the rice-polishing process can be surely executed without waste and the white rice can be produced.

Next, a second embodiment of the present invention will be described. The same reference numerals as those in the first embodiment are given to those basically the same as those in the first embodiment, and the description thereof is omitted.

FIG. 3 is a sectional view showing the configuration of the coin insertion portion 62 of the coin rice polishing apparatus 60 according to the second embodiment.

In the coin insertion section 62, a coin return path 66 branched from the coin insertion path 64 is formed in the middle of the coin insertion path 64. A damper 68 is arranged at a branch position between the coin insertion path 64 and the coin return path 66, and a state in which the coin insertion path 64 is opened and a state in which the coin insertion path 64 is closed and the coin return path 66 is opened. You can move between them.

The damper 68 is connected to the solenoid 70 and is moved by the operation of the solenoid 70. The damper 68 and the solenoid 70 are normally in a state in which the damper 68 closes the coin insertion path 64 and opens only the coin return path 66. The operation of the solenoid 70 moves the damper 68 to move the coin insertion path 64.
Is open. Solenoid 70 is a control circuit
Connected to 72.

The structure of the control circuit 72 is shown in FIGS. 4 (A) and 4 (B). The control circuit 72 has basically the same configuration as the control circuit 36 in the first embodiment described above, but the rice grain sensor
In addition to the rice grain sensor switch 48 and relay coil 50 operated by 34, a relay coil 74 is further connected in series to the power supply. A relay contact 74A that is closed by the excitation of the relay coil 74 and the solenoid 70 described above are connected in series to the power source.

Also in the coin rice polishing apparatus 60 according to this embodiment, when the paddy rice M or the brown rice G is put into the swelling hopper 14, the rice grain sensor 34 detects this and the rice grain sensor switch 48.
Operates and closes. Therefore, the relay coil 50 is excited, the relay contact 50B is closed, and the relay coil 7
4 is excited and relay contact 74A closes. Therefore,
The solenoid 70 operates and the damper 68 moves to open the coin insertion path 64. Therefore, the coin 30 can be practically inserted.

Next, when the coin 30 is inserted into the coin insertion path 64 and the operation switch 28 is operated, the same operation as the coin rice polishing apparatus 10 according to the first embodiment described above is performed and the rice polishing process is performed.

After the rice polishing process, the relay switch 74 is demagnetized by opening the rice grain sensor switch 48, and the relay contact 74
A opens. Therefore, the solenoid 70 returns to its original state, the damper 68 moves, and the coin insertion path 64 is closed. For this reason, the coins 30 that are inserted thereafter become substantially impossible, and the inserted coins 30 are returned through the coin return path 66.

Also in the present embodiment, when rice grains are put into the squeeze hopper 14, this is detected by the rice grain sensor 34, and further,
Only in this case, the rice mill 22 can be driven. In other words, unless rice grains are put into the stake-in hopper 14, the rice polishing machine
22 does not drive. Therefore, erroneous operation of the device can be prevented, and the rice cleaning process can be surely executed without waste and the rice can be polished.

In addition, the rice grain sensor 34
Only when this is detected by the above, the coin insertion path 64 of the coin insertion part 62 is opened and the coin 30 can be inserted, in other words, unless the rice grain is inserted into the stake-in hopper 14, the coin 30 is substantially Users who are unfamiliar with the operation of the device accidentally insert a coin 30
Even if the coin is inserted, the coin 30 is not returned and the device does not operate, so that the erroneous operation is prevented. Further, in this case, since the inserted coin 30 does not remain in the device, it does not cause a failure.

Although the coin-polishing devices 10 and 60 of each of the above embodiments are configured to include the huller 18 and the stone remover 20, the present invention is not limited to this, and the huller 18 or the stone remover 20 is not limited to this. May be omitted.

[Effects of the Invention] As described above, the coin rice polishing apparatus according to the present invention has the following effects.

In the coin rice polishing apparatus according to claim (1), even if a user who is unfamiliar with the operation of the apparatus accidentally inserts a coin before inserting rice grains, the coin is not returned and the apparatus does not operate,
Erroneous operation is prevented. Further, since the inserted coin does not remain in the device, it does not cause a failure.
