The machine room 3 is provided with a first elevator 11, a stone remover 12, a second elevator 13, a rice hopper 14, a rice mill 15, and the like. Then, in accordance with a command from a controller (not shown) built in the operation panel 6, the unpolished rice that has been put into the raw material feeding hopper 5 is removed while being sequentially transferred, subjected to rice milling, and automatically polished to be taken out into the white rice taking-out tank 7. It is configured as follows.

  Although not shown in the drawing, the rice mill 15 is provided with a brown rice sensor in the rice hopper 14 to detect the accumulation of a predetermined amount of brown rice, and a milling roll is disposed in the milling chamber. The resistance plate is provided, and the soot leaking from the net of the semen chamber is sent to the cocoon processing section by the cocoon discharge fan. The milling roll is driven by a rice milling motor, and the resistance plate is moved and adjusted by a resistance plate adjusting motor.

Next, the control contents of the fee-type automatic rice milling equipment will be described with reference to FIG. 1, FIG. 5, and FIG.
In the fee-type automatic rice milling equipment, an opening / closing door 21 that opens and closes while moving the rice loading opening 5 a of the raw material charging hopper 5 in the vertical direction is provided, and the opening / closing door 21 is opened and closed by the opening / closing motor 23.

  An opening direction detection sensor 22 is provided at the lower end of the opening / closing door 21 so that it can be detected whether or not a force equal to or greater than a set value in the opening direction is applied to the opening / closing door 21. As shown in FIG. 6, an opening direction detection sensor 22 is attached to the center of the lower end portion of the open / close door 21 in the left-right direction. At the lower end of the open / close door 21, a contact detection plate 22a and a sensor operation plate 22b are supported so as to be movable up and down through left and right support pins 22c and 22c over the entire left and right width, and protruded downward by a spring 22d. It is fast. When an upward force is applied to the contact detection plate 22a, the contact detection plate 22a and the sensor operation plate 22b move upward along the left and right support pins 22c and 22c, and the sensor operation plate 22b pushes up the switch piece 22e.

  The detection information of the opening direction detection sensor 22 is input to a controller (not shown) of the rice milling equipment, and the opening direction detection sensor 22 applies a force in the opening direction equal to or greater than a predetermined value during the closing operation of the open / close door 21 upward. When it is detected and input to the controller, a closing operation stop command for the opening / closing door 21 is output from the controller to the opening / closing motor 23, and control for stopping the closing operation of the opening / closing door 21 is performed.

  Further, even when the opening direction detection sensor 22 detects an opening direction force greater than or equal to a predetermined value during the opening operation of the opening / closing door 21 and inputs it to the controller, the controller issues a command to continue the opening operation of the opening / closing door 21, Control to continue the opening operation of the door 21 is performed.

  According to the above configuration, when a force in the opening direction greater than a predetermined value is applied during the closing operation of the opening / closing door 21, the closing operation of the opening / closing door 21 is stopped, and the opening direction detection sensor 22 is activated during the opening operation of the opening / closing door 21. Even if a force in the opening direction greater than a predetermined value is detected, the opening / closing door 21 continues to open, so that the opening / closing door 21 can be quickly opened at the start of rice milling, and the user can quickly feed the raw material brown rice into the raw material charging hopper. 5 can be charged. In addition, the user's hand is not caught in the open / close door 21 and it is safe.

Next, the opening / closing control of the door 21 will be described with reference to FIG.
In the open / close control device for the open / close door 21 of the fee-type automatic rice milling equipment, a fully open detection sensor 26 for detecting the fully open state of the open / close door 21 and a fully closed detection sensor 27 for detecting the fully closed state of the open / close door 21 are provided. A fully closed movement time or a fully open movement time (t), which is a movement time from the fully closed position to the fully opened position, is set, and the raw material charging hopper 5 has a rice presence / absence detection sensor 28 for detecting the presence / absence of rice, and rice full detection. A rice full sensor 29 is provided.

  If the fully open detection sensor 26 does not detect movement to the fully open position even after the fully open movement time (t) has elapsed since the opening / closing door 21 has started to move from the fully closed position to the closed side, The movement of the opening / closing door 21 to the open side is temporarily stopped by the movement stop command.

  If the presence / absence detection sensor 28 does not detect the presence of rice even after a predetermined time has elapsed since the opening / closing of the opening / closing door 21 is stopped, the opening / closing door 21 is not open enough to allow the user to insert rice. It is determined that rice cannot be put into the raw material feeding hopper 5, and the opening / closing door 21 is opened to a fully opened position for a predetermined time in accordance with a command from the controller.

According to the above-described configuration, the opening / closing door 21 can be quickly opened at the start of the rice milling operation and the rice milling operation can be started quickly while preventing the seizure of the opening / closing motor 23 as much as possible.
In the opening / closing control device for the opening / closing door 21, the detected closing movement time (t2) is measured when moving from the fully open position to the closing side, and the detected closing movement time (t2) is 1 / of the total closing movement time (t). 2 is, for example, a movement amount determination reference time (t1), and when the detected closing movement time (t2) is shorter than the movement amount determination reference time (t1), that is, when it stops above the reference position S, It determines with having contacted, the movement to the close side of the opening-and-closing door 21 is once stopped, and it opens after a predetermined time (for example, 3 seconds). Further, when the detected closing movement time (t2) is longer than the movement amount determination reference time (t1), that is, when it stops below the reference position S, it is determined that the user's body, hand, etc. are caught, The opening / closing door 21 is immediately moved to the opening side from the movement to the closing side.

According to the said structure, the opening / closing door 21 can be more safely opened and closed with respect to a user by changing the timing of opening operation of the opening / closing door 21 by the stop position of the opening / closing door 21. FIG.
Next, the control device for the open / close door 21 of the charge-type rice milling equipment will be described with reference to FIGS.

The raw material charging hopper 5 is provided with a rice presence / absence detection sensor 28 and a rice full detection sensor 29, and a rice feed-out valve 30 is provided. When the rice presence / absence detection sensor 28 detects the presence of rice, the feeding valve 30 starts to be driven by the command of the controller so as to feed out the rice.

  Further, when the rice full detection sensor 29 detects the presence of rice, when the rice milling operation is started, the door 21 is closed, and the rice milling operation is performed in the closed state. After that, when the operation time for the fee has elapsed and the feeding valve 30 stops feeding rotation, the opening / closing door 21 is once opened so that the user can confirm that all the rice in the raw material charging hopper 5 has been polished. To. When all the rice milling operations are completed, the door 21 is closed after a predetermined time (for example, 5 minutes).

  In the conventional apparatus, when the user inputs a usage fee, the opening / closing door 21 opens, and when the rice milling operation is completed and the user confirmation sensor confirms that the user is no longer in the rice milling facility, the opening / closing door 21 is closed. I was doing. Therefore, it is possible to add additional rice to the raw material input hopper 5 even after the start of the rice milling work. When the charge is insufficient for the input rice, the rice is put in the raw material input hopper 5 when the charge is cut and the rice milling facility is stopped. There was a problem of remaining.

  However, according to the above configuration, when the rice full detection sensor 29 detects the presence of rice, the open / close door 21 is closed after the rice milling operation is started, so that additional rice can be prevented from being introduced and the above-described problems can be solved. Further, since the driving of the feeding valve 30 is stopped and the opening / closing door 21 is once opened simultaneously with the start of the rice milling operation, the user can confirm that there is no rice in the raw material charging hopper 5.

Next, the whiteness control device for the charge-type rice milling equipment will be described with reference to FIGS.
