BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vinegar aligner for a rice stirring device, and more particularly to a cooling air blower for a vinegar aligning process in a rotary bowl for rice stirring.

[0002]

2. Description of the Related Art Conventionally, a rotating ball for stirring rice is rotated upward (fixed position), rice and vinegar are charged and stirred from an upper end charging port, and a supporting box of the ball is turned substantially horizontally to stop intermittently.
A mixture of rice and vinegar is prepared by stirring and mixing rice and vinegar in that state, and ejecting air from a blower provided in the support box through a perforated blower tube protruding into the ball through the tube axis of the ball. Was allowed to cool.

After that, the support base was rotated downward, and the downward mixture (rice and vinegar) in the bowl was stirred into the lower rice bowl.

However, the supplied vinegar easily enters the blower from the perforated blower tube through the tube axis, and the service life of the blower is limited.

Therefore, when the rotating ball is directed upward and downward, the inventor tends to cause the rice in the ball to move toward the wall side of the ball due to the inertia, and the central portion where the perforated blower tube has a low density,
Therefore, it has been found that the air blown from the multi-hole blower tube in the central portion is easily discharged to the atmosphere from the central charging port of the ball, so that the cooling effect is small.

[0006]

DISCLOSURE OF THE INVENTION According to the present invention, air is blown from a multi-hole blower pipe in the central portion of the ball to the rice and vinegar circulating in the bowl in the central portion where the density of the rice is high to improve cooling efficiency. It is intended to increase the service life of the blower by preventing rust damage of the blower due to backflow of vinegar.

[0007]

In order to achieve the above object, the present invention firstly provides a stand machine box at one end of a base plate, and downwards, laterally and upwards are intermittently provided at the upper part of the machine box. A horizontal swing box that stops is supported above the base plate, and a rotation ball having a rice vinegar discharge port is pivotally supported by a vertically rotating tube shaft on both ends of the swing box to move the ball into the swing box. In the rice stirring device rotated by a drive motor inside, the base end portion of the rotary tube shaft is connected to the lateral pipe in the swing box, and one end of the rotary tube shaft is opened at the base end surface of the swing box to rotate the rotation ball. When the rocking is stopped in the horizontal direction, the vinegar aligner in the rice stirring device formed so as to match the opening at one end of the horizontal tube with the ventilation port of the blower provided in the stand machine box. In the state where the one end opening of the pipe and the blower opening of the blower match, the blower Configured to al of the cooling air by vinegar combined machine, in the formed rice stirrer of the first described as to blow air into the rotation the ball.

As shown in FIG. 2, the motor 16 is controlled by providing a protrusion 17 'on a disc 17 fixed to one end of the drive shaft 13 and providing three protrusions 17' on the outer periphery of the disc 17 (first, second, Third) limit switches 18, 18 ′, 18 ″ are provided, and the motor 16 is activated at the timing when the protrusion 17 ′ turns on the limit switches 18, 18 ′, 18 ″ based on the rotation of the disk 17. Stop, so that each of the above drive shafts 1
4 is stopped in the upward direction (the position shown in FIG. 4A), the lateral direction (the position shown in FIG. 4B), and the downward direction (the position shown in FIG. 4C).
When the third limit switch 18 ″ is turned on, the motor is stopped downward (the position shown in FIG. 4C), the motor 16 is then rotated in the reverse direction, and the motor is stopped in the downward direction, the horizontal direction, and the upward direction. Is converted to normal rotation, and this is repeated, whereby the swing arm 3 is intermittently stopped in the forward and reverse directions upward, sideways, downward, sideways, and upward.

The base end of a lateral rocking box 4 is fixed to the tip of the rocking arm 3 and is supported above the base plate 1, and the rocking box 4 is supported.
In addition, the rotation ball 5 having the vinegared rice discharge port 5 ′ is pivotally supported by the vertical rotation tube shaft 6 having both ends opened, and the tube shaft 6 in the swing box 4 is positively or negatively moved through reduction gears 19 and 19 ′. The output shaft 7'of the forward / reverse drive motor 7 is connected, and as shown in FIG. 3, the tube shaft 6 can be rotated alternately in forward, reverse or forward / reverse directions by the motor 7, whereby the rotation ball 5 is rotated.
Is rotated to form a rice stirring device.

The tip end opening 6 "of the pipe shaft 6 is communicated with the lower end of the perforated pipe 20 which is erected in the middle of the ball 5, and the perforated pipe 20 is a blind pipe at the upper end and side face as shown in FIG. In addition, a fine through hole 21 that is parallel or orthogonal to the common center line c between the tube axis 6 and the perforated tube 20 or is round is regularly formed.

The upper part of the rotation ball 5 is a vinegar rice discharge port 5 '.
A stirring rod 22 is formed on the main body side of the ball 5 along the inner circumference of the discharge port 5 ′, and the tip of the stirring rod 22 reaches the outer circumference of the perforated pipe 20. Rice and vinegar are put into the main body 5a of the rotation ball 5 by opening the opening / closing lid 5 ″.

A base end portion 6'of the rotary tube shaft 6 inserted into the swing box 4 via a bearing 6a is supported by a flange 6b and opens into the air box 9, and a side surface of the air box 9 is formed. The horizontal tube 10 that is inserted into and opened in the horizontal direction is horizontally arranged inside the swing box 4.

An extension opening 10 'is formed to such an extent that one end of the horizontal pipe 10 thus constructed is slidably in contact with the side surface of the stand machine box 2 from the base end surface of the swing box 4.

The extension opening 10 'is provided when the rotation ball 5 is stopped to swing sideways as the swing arm 3 swings.
It matches the blower port 11 'of the blower 11 provided in the stand machine box 2 (the state is shown in FIG. 4 (b) and FIG. 5).

The blower port 11 'is opened on the side surface of the machine case 4 on the base plate 1 side, and as shown in FIG.

When performing the vinegar setting operation with the vinegar aligner configured as described above, first, the drive motor 7 and the motor 16 are driven from the position of FIG. While inclining the balls 5, the motor 16 is stopped for a certain period of time when the limit switch 18 'is turned on, and the stirring operation is performed by rotating the spinning balls 5 at the position shown in Fig. 4B. At this time, the extension opening 10 ′ of the lateral pipe 10 and the blower port 11 ′ of the stand machine box 2 match (state of FIG. 4B and FIG. 5). When the limit switch 18 'is turned on, the blower 11 is operated for a predetermined time,
As a result, the cooling air from the blower 11 causes
The air is blown from the fine through holes 21 into the rotating balls 5 through the air box 9 and the rotary tube shaft 6, and the vinegared rice in the balls 5 is stirred and cooled. Here, the drive motor 7 is repeatedly driven and stopped, and the rotation ball 5 is repeatedly rotated and stopped.
When the blow of the blower 11 is stopped, the motor 16 is driven while continuing the rotation of the rotation ball 5,
The rotation ball 5 is further tilted, and the drive of the motor 16 is stopped when the limit switch 18 ″ is turned on (the position shown in FIG. 4C).
While the above rotation is continued, the motor 16 is normally and reversely rotated to swing the rotating ball 5 up and down 2 to 3 times, and the vinegared rice in the ball 5 is lowered into the rice receiving box 24. The above series of operations is stored in advance in a sequencer, a programmable controller or the like, and the drive motor 7, motor 16,
It can be realized by driving the blower 11 at each timing.

The rotation speed of the rotation ball 5 is set so that the falling rice passes through the center of rotation when the ball is in the lateral direction, whereby the air blow from the perforated pipe 20 can be sufficiently cooled.

The lateral direction of the rotation ball 5 is shown in FIG.
By slightly inclining the falling rice as shown in FIG. 6, the falling direction of the rice and the rotation axis c ′ of the ball 5 are slightly crossed to increase the contact between the falling rice and the wind so that the rice can be cooled quickly.

Further, in the upward and downward states of the ball 5, the central portion becomes hollow and air is discharged from the central portion through the vinegar rice discharge port 5'to the outside of the machine, but in this state, the blower 11 automatically stops. Therefore, the efficiency of cooling and blowing the rice can be kept high.

The vinegar solution that flows down through the tube axis 6 of the rotation ball 5 collects in the air box 9 in the rocking box 4, or flows out of the machine from one end of the horizontally fixed tube 10 in the upward and downward directions. However, the service life of the blower 11 can be improved without the risk of flowing into the blower 11.

[0025]

As described above, according to the present invention, in the vinegar-mixing rice stirring device, the air blown from the pipe shaft is in the state where the rotating balls are in the horizontal direction and the rice inside falls in the central portion of the balls. There is an effect that the rice can pass through the central portion and the rice is cooled sufficiently in the central portion of the bowl.

Further, since the air is blown in a state where the one end opening of the lateral pipe and the blower port are aligned in the horizontal state of the rotation ball, the air is not blown into the ball in the upward and downward states of the ball. It is possible to keep the efficiency of cooling and blowing the rice high.

Further, when the vinegar solution flows down through the above-mentioned tube axis of the rotation ball, the vinegar solution accumulates in, for example, the air box in the rocking box,
The service life of the blower can be improved without the risk of flowing into the blower.
