a, 6b. A sprocket 7 is fitted to the extension side end of the support shaft 3, and is screwed integrally to the support shaft 3. The sprocket 7 is chained between the sprocket 7 and the output sprocket 9 of the drive motor 8 so as to be able to transmit the sprocket 7 and constitute a rotary drive unit.

Further, in addition to the drive motor 8, a blower 12 comprising a blower fan 10, a fan motor 11 and the like is provided inside the support frame 5a, and air is supplied from an air inlet 13 provided at an appropriate position of the support frame 5a. It has a configuration that can be introduced. The end of the blow duct 14 connected to the blower 12 is fitted to the end of the hollow support shaft 4. The support shaft 4 is rotatably provided, while the end of the duct 14 is fixed.
A seal is provided to ensure airtightness with the inner surface.

At a fitting portion between the support shaft portion 4 and the support frame 5b, a state is established in which an air discharge duct 17 communicates with the inside of the support shaft portion 4 so that air from the blower is exhausted through the space in the upper and lower pots. And is provided detachably inside the support frame 5b. The support shaft 3 has a lower hook 2 formed in a double wall.
The lower kettle ventilation mechanism includes a blower pipe, an exhaust port, and the like that communicate with the blower to be blown to the outer periphery of the inner kettle.
That is, one end of the blower pipe 19 is connected to the support shaft 3 of the support frame 5a. The end of the air blow pipe 19 is connected and fixed to an appropriate position of the outer pot of the lower pot 2 so as to be able to blow air to the outer periphery of the inner pot. The air blown by the blower 12 is branched and supplied to the rice-cooling air supplied to the inside of the kettle and the ventilation cooling air to the lower kettle 2, and the ventilation of the lower kettle 2 enters from the tangential direction of the kettle and aspirates in a spiral manner.

Reference numeral 21 denotes a connection fitting for connecting the upper shuttle 1 and the lower shuttle 2. Although not shown, the lower pot 2 is appropriately provided with a shaving bar in a cross state, which is effective for loosening rice rice when stirring and mixing by rotation.

In the above arrangement, the control unit 22 controls the rotation of the shuttles 1 and 2 and the operation of the blower 12. The control unit 22 receives operation signals from various switches provided on the operation panel 23 and inputs sensor detection signals such as a reference stop position detection sensor and a discharge position detection sensor, which will be described later. 8 and blower 11
Is a configuration for outputting a drive stop signal. Operation panel 23
The surface is divided into a left half where the operation switches are arranged and a right half where various settings are made, and consideration is given to facilitating operation and reducing erroneous operations. The left half operation switch includes a power switch 25, a start switch 26,
An automatic operation switch 27, a sharpening switch 28, a manual switch 29, a repetition switch 30, and a seven-segment time display unit 31 are provided. In the right half, there are “Run”, “Maze” (rotating the hook), “Murashi” (blasting time after stopping the shuttle), “Intermittent” (intermittent rotating time of the shuttle), and “Blowing” (blasting time). A mode selection switch 32 for setting each time, a plus switch 33 and a minus switch 34 for increasing / decreasing the mode selection switch 32 and the timer time.
There are provided a setting switch 35 for setting an arbitrary course in combination with the above, and a group of course switches 36 for fixing or calling these courses set and inputted. The control unit 22 has a built-in timer. An LED lamp 37 is arranged above each switch of the mode selection switch 32 so that a mode setting display and a currently running mode can be displayed. These mode selection switches are combined with the operation of the timer switches 33 and 34, and the "operation" switch sets the total operation time for one operation, and the "mix" sets the mixing operation time from the start of operation. “Murashi” sets the murashi time from the mixing work time, and “Intermittent” sets the intermittent stop time until the end of operation. “Blow” sets the time at which the blast cooling starts. In the "cooling", various settings such as setting a start time of cooling by blowing air to the outer pot portion are performed, and a course can be set by a combination of these settings. An example is shown in FIG.

The control section 22 has the following functions. By turning on the automatic operation switch 27 and the start switch 26, automatic operation is executed based on the course selected in advance by the course switch 36. Upon receiving the output automatic driving signal, the automatic driving is performed according to a preset course. For example, the drive motor 8 is started, the shuttles 1 and 2 are rotated for a predetermined time, and simultaneously the blower 12 is started to start blowing. Further, the control unit 22 has the following function when the rotation of the shuttle is stopped. After the predetermined time elapses, the shuttle rotation stop signal is output. However, the drive motor 8 is stopped immediately without receiving the detection output of the reference stop position detection sensor 38 without stopping. Specifically, the upper shuttle 1 of the shuttles 1 and 2 is stopped in a gentle inclination state slightly inclined toward the discharge position (FIG. 1A). Further, when the shredder switch 28 is turned on in the stop mode, the discharge position detection sensor 39 is turned on.
Drive motor 8 is started until the position
2 is a steep angle at which the opening of the lower hook 2 is further downward (FIG. 1).
(B)). When it is desired to obtain a steeper angle from the position detected by the discharge position detection sensor 39, the sharpening switch 28 is continuously turned on. That is, the lower shuttle 1 is gradually rotated according to the ON time of the sharpening switch 28 and the sharpening switch 2 is turned on.
Stop when 8 is turned off. When the cumulative ON time exceeds a predetermined ON time (for example, 4 seconds), the motor returns to the standard position after making one full rotation. Therefore, the inclination can be steeply increased to the maximum inclination angle by the cumulative on-time management. However, the cost can be reduced by managing the above-mentioned time without providing a separate sensor at the maximum angle position.

The reference stop position detection sensor 38 and the discharge position detection sensor 39 are provided on the outer periphery of the sprocket 7. That is, the sensors 38 and 39 are in the form of a reed switch, and are configured to detect a magnetic material (not shown) provided appropriately on the outer periphery of the sprocket 7 and output a detection signal. These detection sensors 38 and 39 are appropriately fixed to the machine frame by mounting plates 40 and 41. The reference stop position detection sensor 38 has a gentle inclination angle in which the open upper surface of the lower shuttle 3 is slightly lower than the horizontal state. The discharge position detection sensor 39 is set to have a slightly steeper angle than this. Further, the discharge position detection sensor 39
The mounting plate 41 is formed with a long hole so that the angle at which the sensor 39 is fixed can be freely adjusted along the outer periphery of the sprocket 7.

The operation of the above example will be described. The upper kettles 1 of the kettles 1 and 2 at the detection position of the reference position stop sensor 38 are removed, and a required amount of cooked rice and vinegar required therefor are introduced. Kamigama 1
The operation start switch 26 is
Turn on. The drive motor 8 starts and the shuttles 1 and 2 start rotating. The cooked rice inside is turned back and stirred by the rotation of the pot. During this time, it is mixed with vinegar without any restriction. By the way, outside air is supplied into the kettle by the operation of the blower 12. In other words, the rotation of the fan motor 11 activates the blower fan 10 and air is introduced from the air inlet 13, reaches the inside of the pot via the blower duct 14 and the support shaft 3, and acts on the stirred rice. Can be cooled. During the stirring and mixing operation, air is blown to the outer periphery of the inner pot of the lower pot 2 via the air pipe 19, the air connection pipe 21 and the like, and the lower pot 2 is air-cooled.

When the operating time of the course set in advance according to the amount of cooked rice, the quality of rice and the like has elapsed, the drive motor 8 automatically stops rotating. That is, control is performed to automatically stop at the position detected by the reference stop position detection sensor 38 (the position (a) in FIG. 1). Next, the lower pot 2 is easy to take out and take out all the rice,
For example, the sharpening switch 28 is turned on so that the lower shuttle 2 stops at a position where the lower hook 2 is steeply inclined toward the unloading worker. By this operation, the lower shuttle 2 is stopped at the position detected by the discharge position detection sensor 39 ((b) in the figure). The stop position of the discharge position detection sensor 39 can be arbitrarily set according to the height of the apparatus and the physique of the unloading worker since the mounting position of the sensor 39 can be adjusted within the range of the angle (C).

If the inclination angle is still required, the shredder switch 28 is turned on. During this ON time, the drive motor starts and rotates until the switch 28 is turned off, so that a desired inclination angle can be obtained.

When the operation of taking out the cooked rice from the lower pot 2 is completed, the sharpening switch 28 is continuously turned on. For example, when the accumulated ON time becomes 4 seconds or more, the lower shuttle 2 is moved to the position detected by the reference stop position detection sensor 38 ((A) in FIG. 1).
