Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a quantitative measuring device using a raw material whose specific gravity changes by pressurization, such as noodles, as an object to be measured.

[0002]

2. Description of the Related Art Conventionally, for example, as a quantitative measuring device for noodles, there is a pressurization type apparatus in which noodles are stored in a raw material container and the noodles are mechanically pushed out from the raw material container at a constant pressure. Are known.

[0003]

However, in the quantitative weighing device using the mechanical pressurizing method as described above, when the object to be weighed is one whose specific gravity changes due to pressurization, such as noodles, There is a problem in that the amount of extrusion with respect to the applied pressure is not constant each time the measurement is performed, and the measurement is not uniform, so that accurate measurement cannot be performed.

The present invention has been made in view of the above problems, and even if the specific gravity of the object to be weighed is changed by pressurization such as noodles, there is no variation in the weighing. An object of the present invention is to provide a quantitative measuring device capable of continuously and reliably measuring a fixed amount.

[0005]

In order to solve the above-mentioned problems, in the quantitative weighing device of the present invention, a container tube for the object to be weighed, which has an inlet at the upper end and an outlet at the lower end, A shield piston lid fitted vertically slidably into the housing tube, a measuring cup connected to the outlet of the housing tube via a press-fitting cup, and a bottom surface of the measuring cup provided to face each other. A filter, a vacuum suction device for depressurizing the inside of the containing tube from the filter through the measuring cup and the press-fitting cup, and the press-fitting cup together with the measuring cup so that the lower end of the containing tube is pushed into the press-in cup. Elevating means for raising, moving means for moving the measuring cup to a predetermined discharging position, and a discharging hand for discharging the measured object to be weighed from the measuring cup at the discharging position. It has a, and.

[0006]

[Function] Explaining noodles as the objects to be weighed, first, put the noodles into the accommodation tube through the upper inlet,
Install the shield piston lid from above.

Next, the vacuum suction device is actuated to depressurize and degas the inside of the containing tube from the filter through the measuring cup and the press-fitting cup, whereby the noodles in the containing tube are discharged from the outlet into the press-fitting cup and measuring. The cup is suction filled with a certain density.

In this case, the noodles are compressed in volume in the receiving tube and move downwards by filling the press-fitting cup and the measuring cup. Following this, the shield piston lid slides downward in the receiving tube. Since it moves, it is possible to perform suction filling by the above-mentioned decompression. Further, the density of noodles is set by the pressure reducing force of the vacuum suction device.

Next, the press-fitting cup ascends together with the measuring cup by the elevating means so that the lower end of the storage tube is pushed into the press-fitting cup. As a result, the noodles in the press-fitting cup are press-fitted in the measuring cup.

The press-fitting pressure in this case can be freely set by adjusting the rising pressure of the press-fitting cup by the elevating means, thereby stabilizing the density of the noodles filled in the measuring cup and improving the measuring accuracy. Can be improved. For example, even when the decompression force by the vacuum suction device is not constant due to clogging of the filter, the noodles can be filled in the measuring cup with a stable density.

Next, the measuring cup is moved to a predetermined discharge position by the moving means, and here the discharged noodles are discharged from the measuring cup into the predetermined container. Then, the measuring cup returns to the initial position, and one cycle of measuring is completed. After that, while repeating the above-mentioned operation, the noodles in the receiving tube are measured one after another and discharged.

A slide cylinder 41 serving as a moving means is fixed on the support plate 5. When the measuring cup 4 is moved to the discharge position, the press-fitting cup 3 is supported by the shutter 40 with its lower end closed.

The press-fitting cup 3 is moved up and down together with the measuring cup 4 by the lower lifting cylinder 3a and the upper lifting cylinder 3b, which serve as lifting means, so that the lower end tube portion 10 of the housing tube 1 is pushed into the inside thereof.
