  For example, as shown in FIG. 4, the revolving device 21 includes a main sprocket 23 and a driven sprocket 24 that are rotatably supported at positions adjacent to each other with a predetermined inter-axis distance. A rotation shaft of a drive motor 22 (see FIG. 2) is connected to the main sprocket 23 and is rotated by driving of the drive motor 22. The circling device 21 can freely change the rotation speed of the main sprocket 23 by the drive control of the drive motor 22.

  A chain 25 is stretched between the main sprocket 23 and the driven sprocket 24 to form an elliptical circular orbit. A plurality of stirring blades 31 are suspended and fixed to the chain 25 at equal intervals. The stirring blade 31 is swung along an elliptical orbit by the drive motor 22 and can be rotated clockwise and counterclockwise. In this embodiment, the counterclockwise direction which is one side in the circumferential direction is set as the stirring direction Fk, and the clockwise direction which is the other side in the circumferential direction is set as the leveling direction Fn. Further, in the present embodiment, an elliptical circular orbit is used, which is made to match the shape of the bottom surface 3a of the rice cooker 3, for example, the bottom surface 3a of the rice cooker 3 has a substantially circular shape in plan view. Is configured to form a circular orbit.

  As shown in FIGS. 1 and 3, the stirring blade 31 is reciprocated between the retracted position A and the preparation position B by horizontally moving the slide table 16 by the horizontal movement actuator 17. The preparation position B is set above the rice cooker 3 held at the holding position, and the retreat position A is set at a position moved in the transport direction of the transport conveyor 2 from the preparation position B.

At the leveled height position, the amount of food accommodated in the rice cooker 3 and the shape of the rice cooking pot 3 are determined. In addition, the stirring blade 31 can be stopped at a preferred height position. In this embodiment, air cylinders are used for the lift actuator 15 and the horizontal movement actuator 17, but a hydraulic cylinder, a movement mechanism using a rack and pinion, or a movement mechanism such as a ball screw may be used instead of the air cylinder. it can. In particular, when the leveling height position of the stirring blade 31 is accurately controlled according to the height position of the surface Lf of the food material layer, it is preferable to use a moving mechanism such as a rack and pinion or a moving mechanism such as a ball screw. .

  5A and 5B are diagrams for explaining the configuration of the stirring blade. FIG. 5A is a front view, FIG. 5B is a side view, and FIG. 5C is an enlarged view of the main part of FIG. FIG.

  As shown in FIGS. 5A and 5B, the stirring blade 31 has an upper member 32 that is erected and a lower member 33 that is supported by being inclined at the lower end of the upper member 32. . The upper member 32 is connected to the chain 25 via the connecting portion 53. The connecting portion 53 is provided to hang down from the chain 25, and the lower end is coupled to the base portion 52 of the upper member 32.

  The lower member 33 has an inclined plate 41 that spreads in a plane in a direction intersecting the circumferential direction and is inclined upward toward the stirring direction that is one side of the circumferential direction, and the upper member 32 intersects the circumferential direction. It has a rod-like body 51 whose lateral width in the direction to be narrower than that of the inclined plate 41.

  The upper member 32 has a base portion 52 that extends from the connecting portion 53 in a direction intersecting the circumferential direction (lateral width direction), and the rod-like body 51 protrudes vertically downward from the base portion 52. Is provided. The rod-like body 51 forms an opening on the inclined plate 41 that serves as a food passage portion through which food and water scooped up by the inclined plate 41 of the lower member 33 can be passed.

  The rod-shaped body 51 is made of, for example, a round bar having a circular cross section, and is bent toward the stirring direction Fk at a predetermined height position. By attaching the inclined plate 41 to the lower end of the rod-like body 51, the rod-like body 51 can support the inclined plate 41 as a whole in a tilted state with a simple structure.

  In this embodiment, three rod-like bodies 51 are provided along the base portion 52, and are comb-like at predetermined intervals so that the food and water scooped up by the inclined plate 41 can pass therethrough. Is arranged. The number of the rod-shaped bodies 51 is not limited to three, and may be any one as long as it can support the inclined plate 41 and can form an upper space above the inclined plate 41 through which food and water can pass. But you can. As in the present embodiment, the support rigidity of the inclined plate 41 can be further improved without reducing the opening on the inclined plate 41 by making the number of the rod-like bodies 51 into three to make a comb shape.

  The inclined plate 41 is fixed to the lower ends of the three rod-like bodies 51 and is inclined at an inclination angle θ. The inclined plate 41 has a stirring surface 41A inclined upward in the stirring direction Fk and a leveling surface 41B inclined downward in the leveling direction Fn. The inclination angle θ of the inclined plate 41 is preferably in the range of 30 to 60 degrees, and an angle of 45 degrees is particularly optimal.

  The stirring blade 31 can scoop up food and water with the inclined plate 41 by circling in the stirring direction in the rice cooker 3. Then, the food and water scooped up by the inclined plate 41 can be passed through the opening on the inclined plate 41. Accordingly, the food and water can be efficiently stirred without causing the food to stagnate in front of the stirring blade 31. Moreover, the stirring blade 31 can be leveled evenly by stroking the surface Lf of the food material layer of the rice cooker 3 with the inclined plate 41 by circling in the leveling direction in the rice cooker 3.

  As shown in FIG. 5C, the inclined plate 41 has a fixing portion 42 that is fixed to the lower end of the rod-like body 51 and a spatula portion 43 that protrudes downward from the fixing portion 42. The fixing portion 42 is made of a hard resin material such as engineering plastic, and has a flat plate shape extending in the lateral direction with a predetermined plate thickness and height width. And the upper end surface 42c is joined to the lower end of the rod-shaped body 51, and the whole is supported in the attitude | position which inclined along the inclination of the rod-shaped body 51. FIG. The fixing portion 42 is inclined such that the upper end surface 42c and the lower inclined surface 42b are directed toward the leveling direction Fn, and the upper inclined surface 42a and the lower end surface 42d are inclined so as to be directed to the stirring direction Fk.

  The spatula portion 43 is made of a soft resin material such as silicon rubber, and has a flat plate shape having a larger area than the fixed portion 42. The upper portion of the lower inclined surface 43b is fixed to the upper inclined surface 42a of the fixing portion 42, and is supported in a state where the entire portion is inclined along the inclination of the fixing portion 42. It protrudes. The spatula portion 43 is inclined such that the upper end surface 43c and the lower inclined surface 43b are directed toward the leveling direction Fn, and the upper inclined surface 43a is inclined toward the stirring direction Fk. The lower end of the spatula portion 43 has a linear shape along the bottom surface 3a of the rice cooker 3 in order to prevent a gap from being formed between the bottom surface 3a of the rice cooker 3 and The corners are chamfered (see FIG. 5A).

  The stirring surface 41A of the inclined plate 41 is formed by the upper inclined surface 43a of the spatula portion 43, and the leveling surface 41B is mainly formed by the lower inclined surface 42b of the fixing portion 42 and the lower inclined surface 43b of the spatula portion 43. . The upper inclined surface 43a and the lower inclined surface 43b of the spatula portion 43 are flat surfaces having no irregularities. Therefore, when the stirring blade 31 is rotated in the stirring direction Fk in the rice cooker 3, the ingredients and water scooped up by the spatula portion 43 can be smoothly moved rearward along the upper inclined surface 43a. It can be passed through an opening on the plate 41. Therefore, it can prevent that a foodstuff stagnates before the stirring blade 31, and can stir foodstuff and water efficiently. Moreover, when the stirring blade 31 is made to circulate in the leveling direction Fn in the rice cooker 3, the surface Lf of a foodstuff layer can be stroked by the lower inclined surface 43b, and it can level evenly.

  The fixing part 42 and the spatula part 43 do not have a horizontal surface on which the food material is placed, and a horizontal surface, a concave part, etc. on which the food material is placed are also formed at the joint part with each other and the joint part with the rod-shaped body 51. Absent. In particular, the upper end surface 42 c of the fixing portion 42 is formed to be a surface that is continuous downward from the upper end surface of the spatula portion 43 and is perpendicular to the lower side. Therefore, when the stirring blade 31 is circulated in the leveling direction Fn, the food material in contact with the upper end surface 42c is guided to the lower inclined surface 42b of the fixed portion 42 or the upper end surface 43c of the spatula portion 43, It can be smoothly moved to the rear of the inclined plate 41 along the inclined surface 42b or the upper end surface 43c. Therefore, it is possible to prevent food from being placed on the inclined plate 41. The upper end surface 42c may have a convex curved surface shape with a circular cross section, and the food abutting on the upper end surface 42c can be placed on the lower inclined surface 42b of the fixing portion 42 or on the spatula portion 43. It can be made easier to guide to the end face 43c.

  The spatula portion 43 of the inclined plate 41 is made of a soft resin material. Therefore, even if it contacts the bottom surface 3a of the rice cooker 3, the rice cooker 3 is not damaged, and when the stirring blade 31 is rotated in the stirring direction Fk, the ingredients in contact with the bottom surface 3a are scooped up efficiently. Can be stirred. Moreover, when it is made to circulate in the leveling direction Fn, the entire spatula part 43 can be curved and deformed like a brush, and the surface Lf of the food material layer can be stroked with an appropriate pressing force, and can be leveled flatly. .

  FIG. 6 is a diagram for explaining the operation of the stirring device, FIG. 6 (a) is a cross-sectional view of the main part showing a state where the stirring blades are arranged at the stirring height position, and FIG. 6 (b) is a diagram showing the leveling height of the stirring blades. It is principal part sectional drawing which shows the state arrange | positioned in the position.

  The stirring device 1 is controlled in operation by a control device (not shown). When the rice cooker 3 is transported from the charging stage to the stirring stage by the conveyor 2, the stirring device 1 holds the rice cooker 3 in the holding position by the stopper 12. Then, the stirring blade 31 is disposed from the retracted position A to the preparation position B by the slide table, and is lowered from the preparation position B by the lifting table 14. Then, the stirring blade 31 is rotated in the stirring direction Fk while being lowered. Specifically, simultaneously with the start of the descent, the drive motor 22 of the revolving device 21 is driven to rotate the main sprocket 23 counterclockwise. The rotation of the main sprocket 23 causes the chain 25 to move along an elliptical track. Each stirring blade 31 circulates in the stirring direction along the elliptical orbit in the rice cooker 3 as the chain 25 moves.

  As a result, the stirring blade 31 is inserted from above the rice cooker 3 while circling in the stirring direction Fk, and the inclined plate 41 of the lower member 33 is the food layer in the rice cooker 3 as shown in FIG. Then, it is completely immersed and lowered from the surface Lf of the food material layer to a stirring height position where only the rod-like body 51 of the upper member 32 protrudes, and then circulates in the stirring direction (stirring step).

  Therefore, the stirring surface 41A of the inclined plate 41 can scoop up the food in the rice cooker 3 and pass the opening on the inclined plate 41 together with water, so that the food does not stagnate in front of the stirring blade 31. The ingredients and water can be efficiently stirred and mixed uniformly. As shown in FIG. 5C, the inclined plate 41 does not have a horizontal surface or a concave portion on which the food is placed, so that it is possible to prevent the food from being placed and adhered during stirring.

  Further, since the stirring blade 31 is lowered to the stirring height position while circling in the stirring direction Fk, the tip of the inclined plate 41 is applied to the food layer without applying unnecessary load to the rod-like body 51 and the inclined plate 41 of the stirring blade 31. It can be inserted and smoothly reached to the bottom surface 3a of the rice cooker 3, and appropriate stirring can be started quickly.

  The stirring device 1 can freely change the rotating speed of the stirring blade 31 by the drive control of the drive motor 22 of the rotating device 21. Therefore, for example, the rotation speed can be adjusted according to the type and amount of the food, and stirring suitable for the food can be performed.

  The stirring device 1 circulates the stirring blade 31 in the stirring direction for a predetermined time, stirs the food, for example, collapses the piled state, eliminates the substantial deviation, and then reversely rotates the drive motor 22 of the circulating device 21. The rotating direction of the stirring blade 31 is switched from the stirring direction Fk to the leveling direction Fn, and the stirring blade 31 is raised while rotating in the leveling direction Fn. And as shown in FIG.6 (b), it raises to a leveling height position and complete | finishes a stirring step. Therefore, when raising the stirring blade 31 from the stirring height position to the leveling height position, the direction of the water impinging on the stirring blade 31 can be changed, and the ingredients attached to the stirring blade 31 during stirring are stirred. It can be actively dropped by the flow of water in the direction opposite to the direction Fk.

  Subsequently, the stirring blade 31 is rotated in the leveling direction at the leveling height position (leveling step). The stirring blade 31 is disposed below the water surface Lw with the inclined plate 41 of the lower member 33 completely immersed in the water surface Lw in the rice cooker 3 at the leveling position, and the upper member 32 extending from the water surface Lw. Only the rod-shaped body 51 protrudes (see the position of the water surface Lw in FIG. 5C). Since the joint portion between the lower end of the rod-shaped body 51 and the inclined plate 41 is disposed below the water surface Lw, even when food is attached, when the stirring blade 31 is rotating in a leveling state, Ingredients can be actively dropped by the flow of water.

  The stirring blade 31 can level the surface Lf of the food material layer flatly in the rice cooker 3 by the leveling surface 41B of the inclined plate 41 inclined downward in the leveling direction Fn. The rice can be evenly cooked without uneven cooking.

  Since neither the fixed part 42 nor the spatula part 43 has a horizontal plane, the inclined plate 41 can prevent the food from adhering even in this leveling step. In addition, even if food is attached to the stirring blade 31, the stirring blade 31 is rotated in the leveling direction Fn opposite to the stirring direction Fk to change the direction of the water impinging on the stirring blade 31. It can be dropped from the blade 31.

  When the stirring step and the leveling step are completed, the stirring blade 31 continues the circulation in the leveling direction to the preparation position, and is taken out from the rice cooker 3 by the ascending / descending table and placed at the upper preparation position B. Then, the slide table is moved to the retracted position A. In the retreat position A, a water receiver 18 for receiving water droplets dripping from the stirring blade 31 is provided close to the rice cooker to such an extent that the circulation of the stirring blade 31 is not hindered. Can prevent the surroundings of the apparatus from becoming dirty.

  According to the stirring device 1 of the present invention, since the lower member 33 is supported by being inclined at the lower end of the upper member 32, the lower member 33 does not have a horizontal upper surface, and the stirring blade 31 does not have food during or after stirring. It can be effectively prevented from being placed. Therefore, for example, it is possible to prevent the food material from dropping to a place other than the rice cooker 3 to deteriorate the sanitary environment, or to fall into another rice cooker 3 that has been transported and mixed with the food material.

  According to the stirring device 1 of the present invention, the lower member 33 of the stirring blade 31 spreads in a plane shape in a direction intersecting the circumferential direction, and the inclined plate 41 inclined upward toward the stirring direction on one side of the circumferential direction. The upper member 32 of the stirring blade 31 has a rod-like body 51 whose lateral width in the direction intersecting the circumferential direction is narrower than that of the inclined plate 41. Therefore, the ingredients in the rice cooker 3 can be scooped up by the inclined plate 41 by rotating the stirring blade 31 in the stirring direction Fk. And the food and water scooped up with the inclination board 41 can be passed through the opening formed on the inclination board 41 by the rod-shaped body 51. Accordingly, the food and water can be efficiently stirred without causing the food to stagnate in front of the stirring blade 31.

  According to the stirring device 1 of the present invention, the rotating device 21 selectively switches the rotating direction of the stirring blade 31 to the stirring direction Fk that is one side of the rotating direction, or the leveling direction Fn that is the other side of the rotating direction. Since it is made to circulate, the direction of the water impinging on the stirring blade 31 can be changed oppositely in the stirring direction Fk and the leveling direction Fn, and the food material adhering to the stirring blade 31 can be actively dropped from the stirring blade 31.

  The stirring device 1 of the present invention has a stirring height position in which the lower end of the inclined plate 41 is brought into contact with the bottom surface 3 a of the rice cooking pot 3 by moving the stirring blade 31 and the rice cooking pot 3 relatively up and down. There is provided a lifting table 14 that can be selectively placed at a leveled height position to be brought into contact with the surface Lf of the food material layer. The circling device 21 selects the stirring direction Fk at the stirring height position, and selects the leveling direction Fn at the leveling height position. Therefore, the ingredients in the rice cooker 3 can be scooped up at the stirring height position to efficiently stir the ingredients and water in the rice cooker 3, and the surface Lf of the ingredient layer in the rice cooker 3 can be stroked at the level height position. Can be leveled flat.

  In addition, this invention is not limited to the structure of the above-mentioned embodiment, A various change is possible in the range which does not deviate from the main point of this invention. For example, in the present embodiment, the case where the stirring blade 31 is moved up and down with respect to the rice cooker 3 has been described as an example. However, the rice cooking pot 3 and the stirring blade 31 are moved in a direction in which the rice cooking pot 3 and the stirring blade 31 approach or separate relatively upward and downward. For example, the height position of the stirring blade 31 may be fixed and the rice cooker 3 may be moved up and down.

  Further, the stirring blade 31 is configured to support the inclined plate 41 with the three rod-shaped bodies 51, but the number of the rod-shaped bodies 51 is not limited to three, and the ingredients in the rice cooker 3 are stirred. The inclined plate 41 can be supported with rigidity capable of leveling the surface Lf of the food material layer flat, and an opening through which the food material scooped up by the inclined plate 41 can be passed is formed. What is necessary is just one or more.

  As an application example of the present invention, this stirring device can be used to stir rice and ingredients used in, for example, mixed rice, and can also be used for the purpose of stirring red rice and red beans. Furthermore, it can be used for stirring ingredients and seasonings such as soy sauce.
