Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a residual rice discharge device in an ascending vertical rice mill.

(Prior Art) The conventionally known Japanese Patent Application Laid-Open No. 159853/1985 discloses a horizontal polishing tube, a horizontal feed spiral provided in the horizontal polishing tube,
an annular gap smaller than the grain formed between the outer periphery of the cross-feeding spiral and the inner surface of the horizontal polishing cylinder; and a supply port with a hopper opened at one end of the horizontal polishing cylinder;
a drive motor that rotates the transverse feed spiral;
The document describes a horizontal rice milling machine comprising a switch that energizes the driving motor while there is grain in the hopper and turns off the energizing of the driving motor after a predetermined time when there is no grain in the hopper.

Furthermore, the conventionally known Japanese Utility Model Application Publication No. 59-106549 describes a configuration in which the remaining rice is removed by reversing the drive motor when the drive motor stops working.

(Problems to be Solved by the Invention) When the rice milling device has a horizontal axis, the problem of residual rice hardly occurs. If the rotation continues, the grains will be ejected. In horizontal axis rice milling equipment, clogging of rice is a problem. Rice clogging in the horizontal axis rice milling device is removed by reversing the rice milling rolls. When the rice milling device has a vertical axis and is an upward supply/downward take-out type,
Since the rice falls under its own weight, there is no problem of residual rice.

However, vertical shaft rice milling machines of the downward feed type and the upward take-out type always produce residual rice at the end of feeding.

In this sense, if we look at known examples, in the conventionally known Japanese Patent Application Laid-Open No. 159853/1985, the driving motor is energized while there is grain in the hopper, and when there is no grain in the hopper, a predetermined period of time is elapsed. A switch is provided at the rear to cut off the power to the drive motor, but since it is a horizontal type, it is not a countermeasure against residual rice, but is merely an automatic stop switch.

In addition, the conventionally known Japanese Utility Model Application Publication No. 59-106549 describes a configuration in which the drive motor is reversed to remove the remaining rice. Occurs at the end of supply,
This is not residual rice, but residual rice that is clogged when milling is stopped mid-way through feeding.This is also a countermeasure against residual rice that always occurs at the end of feeding, even with vertical shaft rice milling equipment that is of the downward feed type and is taken out from above. It's not a thing.

However, even with a vertical axis rice milling device of the downward feed type and the upward take-out type, the above two techniques are used.
This can be used to deal with residual rice.

(Means for solving the problem) Therefore, the present invention provides a vertical polishing tube 1, an upward feeding spiral 3 provided in the vertical polishing tube 1, and an outer periphery of the upward feeding spiral 3 and the vertical polishing tube 1. an annular gap 4 smaller than the grain formed between the inner surface and the supply port 5 of the hopper 6 opened at a position below the vertical polishing tube 1; and a supply port 5 of the hopper 6 opened at a position below the supply port 5 of the vertical polishing tube 1. The leftover rice removal port 7, the drive motor 8 that rotates the upward feed spiral 3, and the drive motor 8 are energized while there are grains in the hopper 6, and when there are no grains in the hopper 6, the drive motor 8 is turned on for a predetermined period of time. A residual rice discharging device in an ascending vertical rice mill, which comprises a timer 18 that cuts off the power to the drive motor 8, and a push button switch 14 for starting reverse rotation that starts the reverse rotation only when the drive motor 8 is pressed. It is.

(Example) An example of the present invention will be described with reference to the drawings.
is a vertical polishing cylinder, and a vertical shaft 2 is installed inside it. An upward feed spiral 3 is provided on the outer periphery of the vertical shaft 2. An annular gap 4 between the outer periphery of the upward feeding spiral 3 and the inner surface of the vertical polishing cylinder 1 is formed to be smaller than a grain of rice.

Thus, a supply port 5 is opened at a lower position of the vertical polishing tube 1, and a hopper 6 is attached to the outside of the supply port 5.

A residual rice removal port 7 is formed below the supply port 5. The remaining rice outlet 7 is a
only in the downward position.

Figure 2 is a circuit diagram. 8 is a motor, 9 is a push button switch for forward rotation, 10 is a push button switch for starting forward rotation, 11 is a timer, 12 is a relay, and 13 is a relay contact of relay 12, which starts forward rotation. When the push button switch 10 is turned on, current flows through the relay 12, turning the relay contact 13 on. Thereafter, even if the forward rotation starting pushbutton switch 10 is turned off, the current flows through the forward rotation pushbutton switch 9, the relay contact 13, the timer 11, and the relay 12 for self-preservation. The self-preservation circuit operates the forward rotation push button switch 9.
Turns off when turned OFF.

14 is a push button switch for starting reverse rotation, 15 is a relay, 16 is a relay contact of relay 12, 17 is a level sensor, 18 is a timer, 19 is relay 1
2 is a relay contact of relay 15, and 20 is a relay contact of relay 15.

(effect) Next, we will discuss the effect.

When brown rice is supplied from the hopper 6 and the forward rotation start push button switch 10 is turned on, a current flows from the forward rotation push button switch 9 → the forward rotation start push button switch 10 → the timer 11 → the relay 12, and the relay 12 is activated. Turn on relay contacts 13, 16, and 19.

Therefore, the motor 8 rotates in the normal direction, causing the vertical shaft 2 to rotate in the normal direction, and the upward feeding spiral 3 feeds the grain upward to polish the rice. This rice milling is continued until the grain is exhausted.

When the grain runs out, this is detected by the level sensor 17 and the level sensor 17 is turned OFF, so the circuit of the timer 18 is cut off, and after a predetermined period of time, the timer contact 11 is turned OFF, and the forward rotation push button switch 9 → relay contact 13 →
The circuit from timer contact 11 to relay 12 is broken and relay 12 is turned off, so relay contact 13,
Relay contact 16 and relay contact 19 are all turned OFF to stop motor 8.

However, residual rice remains, so when the reverse start push button switch 14 is pressed, current flows to the relay 15 and turns on the relay contact 20, so the motor 8 is reversed and the grain can be removed from the residual rice outlet 7. can.

The reversal of the vertical shaft 2 is limited to the time when the push button switch 14 for starting reverse rotation is pressed.

(Effects) The present invention provides a vertical polishing tube 1, an upward feeding spiral 3 provided in the vertical polishing tube 1, and grains formed between the outer periphery of the upward feeding spiral 3 and the inner surface of the vertical polishing tube 1. A smaller annular gap 4 and the vertical polishing tube 1
Supply port 5 with hopper 6 opened at a lower position
, a residual rice take-out port 7 opened at a position below the supply port 5 of the vertical milling cylinder 1, a drive motor 8 for rotating the upward feed spiral 3, and a rice hopper 6 in which grains are present. A timer 18 that energizes the drive motor 8 and turns off the energization of the drive motor 8 after a predetermined period of time when the hopper 6 runs out of grain; and a push button switch for starting reverse rotation that causes the drive motor 8 to rotate in reverse only when the drive motor 8 is pressed. 14, the drive motor 8 is energized while there are grains in the hopper 6, and when there are no grains in the hopper 6, the drive motor 8 is turned off after a predetermined period of time. Since a timer 18 is provided to cut off the power to the motor 8, it can be stopped automatically. Further, the residual rice removal port 7 is opened at a position below the supply port 5 of the vertical polishing tube 1, and a push button switch 14 for starting the reverse rotation is provided, which causes the drive motor 8 to reverse only when it is pressed.
The operation is easy and the remaining rice can be removed reliably.
