Description

[Detailed description of the invention] "Industrial Application Field" This invention relates to a rice metering device used in an automatic rice serving machine in the restaurant industry or school lunch industry.

``Prior art'' Conventional rice metering devices alternately open and close shutters at the top and bottom of the metering chamber (Japanese Patent Application Laid-open No. 169421/1982), which is suitable for quantitative measurement.
A cut surface is formed on the top surface of the fixed-quantity plated rice, which spoils the appearance of the fixed-quantity plated rice and lowers the product value.In addition, it is difficult to adjust the quantity of the fixed-quantity plated rice, and also to quickly quantify the quantity and improve the quantitative efficiency. It was hot.

``Problems that the invention attempts to solve'' This idea adjusts the amount of fixed-dose rice, and also improves the appearance of fixed-dose rice by not forming a shutter cut surface on the top of the fixed-dose rice and serving it in a hand-shaped manner. This is an attempt to improve the plating efficiency.

``Means for solving the problem'' The present invention provides a cylindrical discharge part at the bottom of the rice supply hopper, and a rice measuring basin is installed in the discharge part. There is a rice metering device comprising: a closing speed adjusting device for an upper opening/closing shutter.

"Function" Therefore, the upper shutters 5, 5 are opened and the lower shutters 6, 6 are closed from the upper hopper 1.
Rice is served on top. That is, rice is stored in and above the metering chamber 7. Then, at the same time as opening the lower shutters 6, 6, the upper shutters 5,
5 closes, but if the closing speed is fast, the amount of rice will be measured at a slightly higher amount than the amount in the measuring box 7, and if the closing speed is slow, the amount of rice will be measured at a much larger amount than the amount in the measuring box 7, and the amount will be adjusted by adjusting the closing speed. It can be adjusted by the device 11.

"Example" A rotary comb 2 for lowering rice is provided at the bottom of a hopper 1 provided in a heat insulating box, a cylindrical discharge part 3 is connected to the hopper 1 at the bottom, and a cylindrical discharge part 3 is connected to the hopper 1 in the middle of the hopper 1. A food measuring box 7 is formed by a surface 4 and upper and lower opening/closing shutters 5, 5 and 6, 6. These opening/closing shutters 5, 5 and 6, 6 each penetrate the wall of the discharge section 3 to shut off and open the inside of the discharge section 3, and perform opening/closing operations by air cylinders 8, 8 provided on the outside of the wall. . The air cylinders 8, 8 of the upper opening/closing shutters 5, 5 are connected to the upper shutters 5, 5 by interposing a flow rate regulating valve 10 in the closing side piping 9 and manually adjusting the valve 10, as shown in FIG. The closing speed of the closing speed can be adjusted and forms a closing speed adjusting device 11. The outer ends of the upper shutters 5, 5 are connected to one end of a reciprocating rotary ram, and the other end roller of the ram is guided to the cam groove of the rotating cam, so that one end of the ram is reciprocated in the horizontal direction, thereby causing the upper shutter 5 to move. , 5, the closing speed adjusting device 11 for the upper shutters 5, 5 can be used to adjust the speed of a variable speed motor for driving a rotary cam. As shown in FIG. 4, the opening speed of the lower shutters 6, 6 is made faster than the closing speed of the upper shutters 5, 5. In the figure, 12 indicates the shutter open side pipe, 13 indicates a switching valve between the open side pipe 12 and the closed side pipe 9, 14 indicates a compressed air source, 15 indicates a rice serving table directly below the discharge section 3, and 16 indicates a serving plate. Serving table 1
5. It is a bowl placed on top.

``Effects'' Since the present invention is configured as described above, it is possible not only to adjust the quantity of the fixed amount of plated rice as required (for example, the size of the bowl) based on the quantity determined by the fixed quantity box 7, but also to adjust the quantity of the fixed quantity of plated rice as needed (for example, the size of the bowl). This has the advantage that the food can be plated in a natural manner without creating a shutter cut surface, and that it can be plated quickly, which improves the efficiency of plating.
