[0022]
The elevating head unit 5 is supported to be movable up and down with respect to the machine base frame 15. A ball screw shaft 25 that is rotatably supported by the machine base frame 15 is screwed to the elevating head unit 5. The ball screw shaft 25 is linked to a head lifting motor 27 on the machine base frame 15 side. The head lifting / lowering motor 27 is composed of, for example, a pulse motor.
[0023]
The rotary shafts 7 and 9 are provided in a pair of upper and lower sides and are rotatably supported by the elevating head unit 5. The rotary shafts 7 and 9 are interlocked by meshing the gears 29 and 31 and rotate in opposite directions. An agitation drive motor 35 as an agitation actuator is linked to the rotary shaft 7 via a speed reducer 33. The rotary shafts 7 and 9 can reciprocate within a predetermined angle range by the rotational drive of the agitation drive motor 35. The stirring drive motor 35 is composed of, for example, a pulse motor.
[0024]
The stirring blades 11 and 13 are attached to the tips of the rotating shafts 7 and 9 via swinging arms 37 and 39, respectively. The stirring blades 11 and 13 are formed in a paddle shape, for example, with resin. The stirring blades 11 and 13 are disposed asymmetrically with respect to the bottom center of the cooking bowl 3. Thereby, stirring efficiency can be improved. One stirring blade 13 is disposed so as to pass through the center of the bottom of the cooking bowl 3. For this reason, the dead point which is the part which is not stirred in the said cooking bowl 3 can be eliminated. In addition, the stirring blades 11 and 13 should just be arrange | positioned so that one may pass the center of the bottom part of the said cooking bowl 3, and the stirring blade 11 may pass the said bottom part center.
[0025]
Coil springs 41 and 43 are housed inside the swing arms 37 and 39. The swing arms 37 and 39 can be elastically extended and contracted via coil springs 41 and 43. Thereby, the stirring blades 11 and 13 can be elastically contacted with the inner wall surface of the cooking ball 3.
[0026]
A plurality of the cooking bowls 3 are prepared in advance on the floor, for example, and ingredients such as vermicelli, spaghetti, pasta before cooking are put into each of them. The setting of the cooking bowl 3 to the machine base frame 15 side is performed by the moving frame 45 as shown in FIG.
[0027]
FIG. 3 is a side view illustrating the arrangement of the cooking bowl 3 and a part of the cooking bowl 3 being seen through or sectioned. At the time of setting the cooking bowl 3, the lifting head unit 5 is driven up by the head lifting motor 27 via the ball screw shaft 25. When the elevating head unit 5 is driven up, the rotary shafts 7 and 9, the stirring blades 11 and 13 and the like ascend as a whole. Further, by the rotational drive of the bowl lifting / lowering motor 23, the lifting / lowering portion 19 is lowered via the ball screw shaft 21, and the platform 17 is set to the lowered position. In this state, the cooking bowl 3 is conveyed by the moving frame 45 and placed on the platform 17 from the front side of the cooking apparatus 1. In this state, the bowl raising / lowering motor 23 is driven to raise the platform 17 contrary to the above. The cooking bowl 3 is set on the platform 17 and is in the state shown in FIG.
[0028]
Next, the stirring drive of the stirring blades 11 and 13 to the cooking bowl 3 is performed by a combination of the lifting and lowering of the lifting head unit 5 and the reciprocating rotation of the rotary shafts 7 and 9. That is, the controller controls the head elevating motor 27 and the agitation driving motor 35 to elevate the elevating head unit 5 and reciprocate the rotary shafts 7 and 9. By the combination of the raising and lowering and the reciprocating rotation, the stirring blades 11 and 13 can be moved along a movement trajectory that accurately corresponds to the inner wall surface of the cooking bowl 3, and the ingredients in the cooking bowl 3 can be stirred in a hand-turned manner.
[0029]
At this time, the bowl rotating actuator 18 is driven to rotate the cooking bowl 3 together with the rotating plate on the platform 17, and the ingredients in the cooking bowl 3 are removed by the rotation of the cooking bowl 3 and the stirring of the stirring blades 11 and 13. Stir cooking can be performed more accurately.
[0030]
FIG. 4 is a cross-sectional view showing the swing range of the rotary shaft 7, and FIG. 5 is a cross-sectional view showing the swing range of the rotary shaft 9. The swing angle α of the rotary shaft 7 at a relatively low position with respect to the rotary shaft 9 is larger than the swing angle β of the rotary shaft 9 at the same high position. Therefore, the range of motion of the stirring blades 11 and 13 relative to the inner surface of the cooking bowl 3 is substantially the same.
[0031]
FIG. 6 is a cross-sectional view showing the motion trajectory of the stirring blade 11, and circles 47 are each point of the motion trajectory. A line connecting the circles 47 is almost a movement locus of the stirring blade 11. FIG. 7 is a cross-sectional view showing the motion trajectory of the stirring blade 13 similarly, and the circles 49 are the points of the motion trajectory of the stirring blade 13. A line connecting the circles 49 is almost a movement locus of the stirring blade 13. FIG. 8 is a cross-sectional view showing the combined motion trajectory of the stirring blades 11 and 13.
[0032]
As shown in FIGS. 6, 7, and 8, the points 47 and 49 of the motion trajectories of the stirring blades 11 and 13 could be formed along the inner shape of the cooking bowl 3 accurately.
[0033]
9, 10, and 11 are obtained by changing the motion trajectory of the stirring blades 11 and 13, and the motion trajectory swells up and down as compared with FIGS. 6, 7, and 8. 9 corresponds to FIG. 6, FIG. 10 corresponds to FIG. 7, and FIG. 11 corresponds to FIG. The movement trajectory points 47 and 49 are as shown in FIGS. 9 and 10, and a synthesized movement trajectory can be formed as shown in FIG. 11.
[0034]
FIG. 12 corresponds to FIG. 8 and shows the movement locus points 47 and 49 of the stirring blades 11 and 13 together with the locus of the swinging arms 41 and 43. FIG. 13 corresponds to FIG. 11 and shows the movement locus points 47 and 49 of the stirring blades 11 and 13 together with the locus of the swinging arms 41 and 43.
[0035]
As shown in FIGS. 12 and 13, the movement trajectory of the stirring blades 11 and 13 is formed by a combination of raising and lowering (arrow A) of the elevating head unit 5 and reciprocating rotation (arrow B) of the rotary shafts 7 and 9. Yes. In this way, the movement trajectory of the stirring blades 11 and 13 can be formed accurately according to the inner surface of the cooking bowl 3.
[0036]
When the stirring blades 11 and 13 are in contact with the inner wall surface of the cooking bowl 3, they are slightly elastically contacted by the urging force of the coil springs 41 and 43. Thereby, scraping with respect to the cooking bowl 3 of the stirring blades 11 and 13 can be performed exactly, and more accurate stirring cooking can be performed.
[0037]
When the stirring blades 11 and 13 are retracted from the cooking bowl 3, it can be easily performed by raising the elevating head unit 5 by driving the elevating drive motor 27.
[0038]
When the inner shape of the cooking bowl 3 is changed due to the change of the cooking bowl 3, the stirring blades 11 and 13 are manually moved in accordance with the inner shape of the cooking bowl 3, so that the head lifting motor 27 and the stirring drive motor 35 at that time are moved. A drive signal is input to the controller. With this input, the controller can learn the inner shape of the cooking bowl 3 after the change. Therefore, a new movement locus of the stirring blades 11 and 13 can be easily reproduced by driving control of the head lifting motor 27 and the stirring drive motor 35 by the controller. Here, since the head elevating motor 27 and the stirring drive motor 35 are pulse motors, the learning and the reproduction of a new motion locus can be accurately performed. When the cooking bowl 3 is changed, the movement locus can be calculated by directly inputting the shape value or the like of the cooking bowl 3 to the controller.
[0039]
In this way, the motion trajectory of the stirring blades 11 and 13 can be easily matched to the inner shape of the cooking bowl 3. Even if the shape of the cooking bowl 3 is changed, the movement trajectory of the stirring blades 11 and 13 can be easily changed by adjusting and controlling the raising and lowering of the raising and lowering head unit 5 and the reciprocating rotation of the rotary shafts 7 and 9. It is possible to easily cope with the change of the cooking bowl 3.
