The stirrer unit 2 includes a drive motor 34 provided above the stirring base 7, a chain 35 wrapped under the stirring base 7 and driven to rotate by the power of the driving motor 34, The main component is a stirrer 36 attached to the chain 35.

Specifically, the chain 35 is driven by a driving sprocket 37 that is supported substantially directly below the driving motor 34.
And a floating sprocket 38 pivotally supported on the right side of the sprocket 37 (FIG. 7A). The line segment a connecting the axes of the drive sprocket 37 and the idle sprocket 38 is aligned with the longitudinal center line of the rectangular shuttle 5 conveyed downward, and is wound around the sprockets 37, 38. Each of the chains 35 is set so as to fit in the opening 6 of the rectangular hook 5.

A stirrer 36 is mounted on the chain 35 via a bracket 39. In this case, the chain 35 also serves as a guide portion of the stirring tool 36 and a transfer body, and the bracket 39 functions as a transfer body.

The stirrer 36 comprises a handle 40 and stirring blades 41. The handle portion 40 is made of L-shaped steel, and is fixed to the bracket 39 by a fixing member 42 at an upper portion thereof, and is fixed to the stirring blade 41 at a lower portion. The stirring blade 41 has a hawk shape. In addition,
The stirring blade 41 is not limited to a hawk shape, and may be appropriately selected according to the situation, such as a spatula plate 44 having a through hole 43 as shown in FIG.

The stirrer 36 having the above-described structure includes the chain 3
5, the stirrer 36 can revolve while rotating on its own axis, as shown in FIG.

That is, a part of the handle portion 40 is formed on the rotating shaft 45, and the rotating shaft 45 is rotatably held by a bearing 46 fixed to the chain 35.
A pinion 47 is fixed to the upper end of the rack 4 and a rack 4 laid on the back surface of the stirring base 7 so that the pinion 47 forms a movement locus substantially similar to the elliptical guide path around which the chain 35 runs.
8 is engaged.

In the above-described embodiment, the stirrer 36 revolves around an elliptical guide path formed by the chain 35 being wound around two sprockets 37 and 38, as shown in FIG. 7B. In some cases, a substantially rectangular annular guideway revolves along a chain 50 wound around four sprockets 49, and as shown in FIG. 7C, an annular guideway not using a sprocket chain. Sometimes. And when revolving around each of the above guideways, they may rotate. Each of center line segments b and c along the major axis of each guide path in FIGS. 7B and 7C is set so as to coincide with the major axis of the rectangular hook 5. 7A and 7B, the stirrer 36 may be reciprocated along a straight line by rotating the sprockets 37 and 38 forward and backward.

The stirrer 36 may be configured so that the handle 40 and the stirring blade 41 can be exchangeably fitted to the chain 35 as a unit. Alternatively, only the stirring blade 41 may be attached to the handle 40 according to the situation. In some cases, it is possible to replace the device with a user.

In FIG. 1, reference numeral 51 denotes washed rice, 52 denotes a tool, and 53 denotes water.

Next, the operation of the embodiment of the stirrer configured as described above will be described with reference to the flowchart shown in FIG.

A predetermined amount of washing rice 51 and water 53 are supplied into the rectangular kettle 5 by a measuring unit (not shown), and a tool 52 is supplied by a tool supply device (not shown). The rectangular pot 5 is transferred by the conveyor 3. Then, the stirrer enters the operation start state.

After the transportation is started, the rectangular kettle 5 enters the portal frame 4 in which the lifting device 1 is raised.

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

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

In step [2], the drive motor 8 of the elevating device 1 is turned on and the operation is started.
Power of coupling 23 → reduction gear 9 → middle horizontal shaft 10 →
The power 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 lowers the stirring base 7 via the screw cylinder 14 screwed with the vertical axis 13. , And the operation proceeds to step [3].

In step [3], it is determined whether the stirrer unit 2 has been lowered to the lower limit position. That is, if not lowered to the lower limit position, still stirring device unit 2 continues to descend, when lowered to the lower limit position, the signal to the controller side edge is in contact with the lower position limit switch LS ₄ for stirring foundation 7 Is input, and the operation moves to step [4]. Incidentally, when lowered beyond the lower limit position will be the lower limit limit switch LS ₅ informs the emergency act.

In step [4], the power of the drive motor 8 is turned off by the control device, the rotation of the vertical axis 13 is stopped, and the lowering of the stirring device 2 is stopped. Move on to

In step [5], the control device turns on the drive motor 34 and starts operation.
Power rotates the drive sprocket 37 and the chain 35
Is driven to rotate, and the stirring blade 41 held by the chain 35 is turned along the traveling path of the chain 35,
Move on to the operation of step [6].

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

In the step [7], it is determined whether or not the set time has been reached. If the set time has not been reached, the swirling of the stirring blade 41 is continued.
Move on to operation.

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

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

In step [10], it is determined whether or not the stirring device section 2 has reached the upper limit position. If not, the stirring base 7 is further raised. in contact with the upper position limit switch LS ₂ inputs a signal to the control unit proceeds to the operation of the next step [11]. In the case where increased beyond the upper limit position, an uppermost limit switch LS ₁ acts to protect the upper device of the stirring device 2 informs the emergency.

In step [11], the transmission of the drive motor 8 is cut off through the control device, the rising of the agitating device 2 is stopped by stopping the reverse rotation of the vertical axis 13, and in order to wait for the next rectangular kettle 5 to arrive. The operation returns to step [1].

It is to be noted that the above-described flowchart may be configured so that the operations of step [2] and step [5] are performed simultaneously.
