Softly serve cooked rice on the tableware 17 that is waiting at the serving section D, which consists of the free loosening blade 14B.

The operation of the embodiment of the present invention will be described below.
In FIG. 4, the cooked rice 16 supplied to the rice storage chamber 3 rotates the cylindrical body 7 for a predetermined time, that is, a predetermined angle, when the sensor 15 provided in the hopper 2 starts to operate at the start of operation. In this case, since the inside of the hopper 2 is empty, the sensor 15 continues to operate and is then scraped off to rotate the blade 4 1/2 turn in the direction of the arrow in the figure. At this time, the rice block in part A in the figure is scraped by the hopper 2. FIG. 5 shows a mode of cooked rice put into the hopper 2, where a part A1 of cooked rice is filled in the throat section 9 and the remaining cooked rice is left.
A2 is deposited on the upper surface of the cylindrical body 7. This completes the first scraping process. Here, if the sensor 15 cannot detect the accumulation on the upper surface of the cooked rice, as shown in FIG.
Rotate 7 and add cooked rice A2 accumulated on the upper surface to the throat section 9 for additional filling. When the filling level L of the cooked rice reaches the sensor 15, the sensor 15 stops operating and scrapes off to suspend the process.

On the other hand, in the scraping process, the blade 4 is halved.
At the same time it rotates and stops, the conveyor as shown in FIG.
1 moves a predetermined distance in the direction of the arrow and advances the cooked rice in part B to part A. When the filling level of the cooked rice in the throat portion 9 decreases as the arranging work progresses, the sensor 15 operates to rotate the cylindrical body 7 to raise the filled level of the cooked rice. By repeating the above steps, approximately the same amount of cooked rice as the C → D part in FIG. 4 is sequentially supplied to the hopper 2.

On the other hand, the variable metering device 12 operates as follows. That is, in FIGS. 7 and 8, the upper shutter 10 is in the open position and the lower shutter 11 is in the closed position in advance.
The rotary disks 24 are set at the positions of the sensors L1. Here, the cooked rice is filled in the inner cylindrical body 19 through the throat portion 9 of the upper hopper 2 as described above. The throat portion 9 is configured to hold the required filling height of cooked rice.

Prior to the start of arranging work, a sensor corresponding to a required fixed amount, for example, the sensor L1 is selected from a sensor group by a fixed amount selection button (not shown). With the selection of the fixed amount, the rotating disk 24 rotates from the sensor L1 to the sensor L2 or L3 and stops. When the sensor L1 is selected, the disc 24 does not rotate and the quantitative completion signal is transmitted as it is.

The rotation of the disk 24 is carried by an arm via a fulcrum 23.
By 26, it is converted into vertical movement of the outer cylinder body 21, and an operating stroke from the minimum position S1 to the intermediate position S2 and the maximum position S3 can be obtained. It is possible to obtain a plurality of quantitative selection positions like the sensor L2 at arbitrary positions within the operation stroke.

Upon completion of the quantitative determination, the upper shutter 10 is closed,
Then, the lower shutter 11 is opened and the cooked rice in the meter is discharged downward. When the rice is discharged, the lower shutter 11 is closed and the upper shutter 10 is opened to complete the basic assembling process. Quantitative selection sensor is at a position other than L1, for example sensor L3
When is selected, the operation mode of the process is as follows.
That is, the circular plate 24 rotates from the starting point L1 to L3, transmits a fixed quantity completion signal, closes the upper shutter 10, and then opens the lower shutter 11, and the cooked rice in the fixed quantity is discharged. The lower shutter 11 closes as the cooked rice is discharged. Simultaneously with the start of the closing operation of the lower shutter 11, the disk 24 rotates in the reverse direction from the position of L3 and returns to the starting point L1 and stops. At the same time when the circular plate 24 returns to the starting point, the upper shutter 10 is opened, the cooked rice is filled in the inner cylindrical body 19, and the assembling process is completed.

As described above, according to the variable quantification device 12 of the embodiment of the present invention, the position of the quantification device is returned to the starting point, that is, the minimum position upon the completion of one plating step, and is prepared for the next quantitative selection. Therefore, it is possible to obtain a smooth discharge performance of cooked rice while maintaining accurate quantification accuracy without compressing the cooked rice in the quantifier. Further, in addition to the above, when a fixed amount of arranging work is to be performed continuously, it is possible to easily deal with it by using an alternate type quantitative selection button. In addition, it is possible to easily suspend the starting point return operation of the metering device during continuous loading.

The variable quantification device 12 can be modified in various ways other than that shown in the illustrated embodiment. For example, instead of vertically moving an arm by a crank mechanism, a rack or worm mechanism, or a chain, a wire, or a gear is used to directly or indirectly drive the outer cylinder up and down, or around the rotating disk. The design can be changed, for example, in the case where the arranged sensor groups are arranged in a straight line for detection.

[0026]

The device of the present invention has a structure in which cooked rice stored in a rice storage chamber is intermittently moved in the horizontal direction, and a portion of the cooked rice which is sticking out is scraped downward by a rotary blade provided in front of the cooked rice. A fixed amount can be supplied to the hopper in a fluffy state without being compressed.

In the apparatus of the present invention, the transfer distance of the conveyor can be arbitrarily adjusted by the timer by moving the conveyor slightly. Therefore, the amount of cooked rice supplied to the hopper can be made variable, and it has a notable function capable of responding to high and low pitches. By using the bottom plate of the rice storage chamber as a conveyor, the device of the present invention does not scrape the cooked rice in the rice storage chamber, does not grind the cooked rice by this, and makes it possible to supply rice to the rice storage chamber successively.

In the device of the present invention, since the side surface of the hopper is made into a rotatable cylindrical body, the rice is finely supplied to the throat, the filling amount of the throat can be kept constant, and the quantitative accuracy is further improved. Can be stabilized. In the device of the present invention, by disposing the rotary cylinder on the side surface of the hopper, it is possible to completely eliminate the bridge of cooked rice found in the hopper having the conventional inclined side surface, and the performance stability of the device is dramatically improved. Can be made

Since the device of the present invention has the rice storage chamber and the rotary cylinder is arranged on the side surface of the hopper, the overall height of the hopper can be remarkably reduced as compared with the conventional hopper having the side surface having an inclination greater than the angle of repose. Therefore, it is possible to provide a device having a compact shape and a large amount of stored rice.
