2. Description of the Related Art In a conventional batch-type rice cooking system, a metering unit is used to wash a predetermined amount of rice and water, an additive supply unit is used to supply a predetermined amount of seasoning liquid, and an ingredient feeder supplies a predetermined amount of rice. Since the ingredients are supplied respectively and the washed rice, the seasoning liquid and the ingredients are in a state of being accumulated respectively, it is necessary to level them and mix them.

As a conventional means for leveling and mixing, there is a stirrer in which a fork-shaped leveling plate is attached to the tip of a shaft, and the shaft moves up and down along the center of a circular pot and rotates. It is unsuitable for, and as shown in FIGS. 9 and 10, a mixer has been developed which operates a stirrer with a through hole-equipped Skiffera-shaped leveling plate attached to the shaft tip in the longitudinal (left-right) direction inside the rectangular kettle. ing.

[0004]

However, in the stirrer according to the development, the utensils, rice, etc. are biased toward the left and right ends of the rectangular pot, so that the stirring is uneven and uniform rice cannot be cooked. The present invention has been made to solve such a problem, and an object of the present invention is to provide a stirrer capable of smoothly and efficiently stirring and obtaining a highly accurate mixed rice product. ..

[0005]

In order to achieve the above object, according to the present invention, a stirring base is moved up and down so as to face an opening of a rectangular kettle mounted on a gate-shaped frame straddling a conveyor and transferred by the conveyor. A stirrer comprising a stirrer elevating and lowering device part for raising and lowering and a stirrer part for interlocking and mixing rice washing, ingredients, etc. in the pot by being interlocked with a driving means mounted on the stirrer base. The driving means mounted on the agitator comprises a driving body provided on the stirring base, an annular guide portion provided on the stirring base, and a moving body that moves along the guiding portion by the power of the driving body. A stirring tool is attached to the moving body.

In FIG. 1, 51 is washed rice, 52 is ingredient and 53 is water.

Next, the operation of the embodiment of the stirrer constructed as described above will be described with reference to the flow chart shown in FIG.

A metering unit (not shown) supplies a predetermined amount of rice washing 51 and water 53 into the rectangular kettle 5, and an ingredient feeder 52 (not shown) feeds the ingredient 52 into the rectangular kettle 5. The rectangular kettle 5 is transferred by the conveyor 3. Then, the stirrer is put into operation.

After the start of the operation, the rectangular shuttle 5 enters the gate-shaped frame 4 in which the lifting / lowering device section 1 is elevated.

At this time, the shuttle confirmation limit switch LS ₃ comes into contact with the outer circumference of the rectangular shuttle 5 and is turned on to instruct a controller (not shown) (incorporating a relay) to stop the conveyor 3 and lower the elevator device 1. A signal is input.

In step [1], it is judged whether the rectangular pot 5 is positioned directly below the stirring base 7 based on the signal. If not positioned, the shuttle 5 is further moved forward by driving the conveyor 3. On the other hand, if the positioning is completed, the conveyor 3 stops and the rectangular shuttle 5 also stops, and the operation proceeds to step [2].

In step [2], the drive motor 8 of the elevator device 1 is turned on to start the operation, and the motor 8
Power of the coupling 23 → reducer 9 → intermediate horizontal axis 10 →
It is transmitted to the vertical axis 13 via the transmission path from the coupling 24 to the gear box 11, and the rotation of the vertical axis 13 causes the stirring base 7 to descend via the screw cylinder 14 screwed to the vertical axis 13 and the stirring device section 2 Then, the operation moves to step [3].

In step [3], it is determined whether or not the stirring device section 2 has descended to the lower limit position. That is, unless the lower limit position is reached, the stirring device section 2 continues lowering, and when the lower limit position is reached, the side edge of the stirring base 7 comes into contact with the lower position limit switch LS ₄ to signal the control device. Is input, and the operation proceeds to step [4]. If the lower limit position is exceeded, the lower limit switch LS ₅ operates to notify an emergency.

In step [4], the power supply of the drive motor 8 is cut off by the control device, the rotation of the vertical axis 13 is stopped, and the descending of the agitator unit 2 is stopped, and the operation of step [5] is performed. Move on to.

At step [5], the drive motor 34 is turned on by the control device to start operation, and the motor 34 is started.
Drive the drive sprocket 37 to rotate the chain 35
To drive the stirring blade 41 held by the chain 35 to rotate along the running path of the chain 35,
Move on to the operation in step [6].

In step [6], counting of the set time for which the stirring blade 41 turns is started, and step [7]
Move on to the operation.

In step [7], it is judged whether or not the set time has been reached, and if not reached, the stirring blade 41 continues to turn, and if reached, the counting is ended and step [8]
Move on to the operation.

In step [8], the swirling of the stirring blade 41 is stopped. For the stop, the operation of the drive motor 34, which is the drive source, is stopped through the control device, and the operation proceeds to step [9].

In step [9], the vertical axis 13 is reversed by the control unit to raise the stirring base 7 via the screw cylinder 14 to raise the stirring unit 2.
Move on to the operation in step [10].

In step [10], it is judged whether or not the stirring device section 2 has reached the upper limit position, and if not reached, the stirring base 7 is further raised, and if reached, the side edge of the stirring base 7 is moved. The upper position limit switch LS ₂ is contacted to input a signal to the control device, and the operation proceeds to the next step [11]. If the upper limit position is exceeded, the upper limit limit switch LS ₁ operates to notify an emergency and protect the upper part of the stirring device section 2.

In step [11], the transmission of the drive motor 8 is cut off through the control device, the reverse rotation of the vertical axis 13 is stopped, and the rise of the stirring device section 2 is stopped to wait for the arrival of the next rectangular kettle 5. Return to the operation of step [1].

It should be noted that the above-mentioned flowchart can be operated so that the operations of step [2] and step [5] are performed simultaneously.
