Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weighing device for measuring natto. 2. Description of the Related Art Conventionally, when filling natto into a container, natto is measured in a measuring box and then filled into the container so that a predetermined amount is filled in the container. There is stickiness due to starch, and in the process of moving it into the measuring box, it sticks and the flowability is poor, so natto may be filled with a coarse density in the measuring box, and therefore, into the natto container However, there is a problem that the filling amount of the resin may be insufficient. Conventionally, in order to improve the fluidity, it has been proposed that the surface be treated with Teflon (registered trademark) or fluorinated. However, such a surface film that has been treated with Teflon or fluorinated is cleaned with a scrubber or the like. At the same time, there is a problem that good effects cannot be obtained. [0003] The present invention has been devised in view of the above-mentioned conventional problems, and improves the fluidity of natto.
An object of the present invention is to provide a natto measuring device capable of satisfactorily measuring a predetermined amount and filling the container with natto. The gist of the present invention is to move natto put in a hopper on a vibrating inclined gutter to measure it from an upper nozzle passage. In the natto measuring device configured to drop the natto into the natto container with a predetermined amount of natto weighed by the weighing box, the natto by reducing the frictional resistance in the inclined gutter portion, the upper nozzle passage, and the measuring box. The ridges and flutes that can enhance the fluidity of the material are formed in the flow direction. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic layout diagram of a natto measuring device,
Put natto (boiled beans) in hopper 2
Is moved on the inclined gutter portion 3 provided in a slanting manner below the head, but at this time, vibration is applied by a vibrator 4 provided on the lower portion to move on the inclined gutter portion 3. . A passage frame 5 is provided at an end of the inclined gutter portion 3, and upper nozzle passages 6, 6 are formed in the passage frame 5 so as to penetrate in the up-down direction. A scatter prevention cover 7 is provided to prevent natto from scattering. [0005] In addition, below the passage frame 5, measuring boxes 8, 8 are provided.
The upper shutter plates 9a and 9b are disposed on the upper surfaces of the measuring boxes 8 and 8 so as to be openable and closable, and the upper shutter plates 9a and 9b are respectively connected to the upper air cylinders 10a and 1b.
0b. In addition, a pair of lower shutter plates 11a,
11b, each of which has a lower air cylinder 12b.
a, 12b. Therefore, with the upper shutter plates 9a, 9b opened, natto is dropped into the measuring boxes 8, 8 and filled, and after a predetermined amount is filled, the lower shutter plates 11a, 9b are filled.
11b, a predetermined amount of natto is dropped downward through a lower nozzle passage in a passage cylinder 13 arranged below, and a predetermined amount of natto is moved into a plurality of natto containers 14 and 14 moved by a conveyor. Natto can be filled. In this embodiment, the inclined gutter 3 is configured as shown in an enlarged perspective view in FIG. 2, and a mountain-shaped ridge T and a vertical groove M are alternately formed on the bottom surface of the inclined gutter 3. And are formed in the vertical direction, that is, along the flow direction of natto. Further, as shown in FIG. 3, similar ridges T and vertical grooves M are alternately formed on the inner peripheral surfaces of the upper nozzle passages 6, 6 penetrated vertically in the passage frame body 5. The ridge T and the vertical groove M are alternately formed in the vertical direction on the inner peripheral surface of the scattering prevention cover 7 so that the ridge T and the vertical groove M are continuous. Further, as shown in FIG. 4, similar vertical ridges T and vertical grooves M are alternately formed on the inner peripheral surface of the measuring box 8. Further, the lower nozzle passage 1 in the passage cylinder 13
Similar ridges T and vertical grooves M are also formed on the inner peripheral surface of 3a. In the present embodiment, the inclined gutter portion 3, the passage frame 5, the measuring box 8, and the passage cylinder 13 are made of stainless steel, and the ridge T and the vertical groove M are integrally formed. As described above, in the present embodiment, the ridges T and the vertical grooves M are formed alternately, so that when the natto moves, the natto moves in contact with the ridge T, and the contact area is larger than in the past. And the frictional resistance is remarkably reduced, so that the fluidity of natto is enhanced. That is, conventionally, since the contact area is large, natto sticks due to the starchy stickiness of natto, the natto sticks, and the flow becomes poor, so that the packing density in the measuring cell 8 may become coarse, and a good measuring function is provided. Although not exhibited, in this example, the flowability is enhanced, so that the natto is filled into the weighing boxes 8 and 8 with a predetermined density, and the natto is filled into the natto container 14 in a state where the predetermined amount is reliably measured. Therefore, a predetermined amount of natto is filled in the natto container 14 without fail, and the filling amount in many natto containers 14 is made uniform. In this embodiment, the inclined gutter portion 3, the passage frame 5, the measuring box 8, and the passage cylinder 13 are each made of stainless steel, so that the surface does not become rough even when scrubbed with a scrubber. Moreover, the protrusions T and the vertical grooves M do not decrease due to friction, and can be cleaned well. In addition, since the sticking of natto to the surface is small, the number of times of cleaning can be reduced as compared with the conventional case, and therefore, the number of times of stopping the natto measuring device 1 can be reduced, and
The operation efficiency is improved. In addition, ridge T, longitudinal groove M
Any shape may be used as long as it can be formed into a slightly curved surface, but can reduce the contact area of natto satisfactorily. According to the present invention, the natto put in the hopper is moved on the vibrating inclined gutter part, dropped from the upper nozzle passage into the measuring box, and a predetermined amount of the natto is measured by the measuring box. In a natto measuring device configured to fill natto into a natto container, a ridge and a flute that can reduce the frictional resistance and increase the flowability of natto flow in the inclined gutter, the upper nozzle passage, and the measuring box in the flow direction. Due to the formation of natto, the natto comes into contact with the ridge, and the contact area is greatly reduced as compared with the conventional method, so that the frictional resistance is reduced, the fluidity of natto is extremely enhanced, and the natto is weighed at a good density. Since the filling is performed in the box and the natto is weighed, a predetermined amount of natto can be surely put in the container, and there is an effect of eliminating weighing errors. In addition, since there is little sticking to the surface, the number of times of cleaning can be reduced, and the number of times of stopping the machine is reduced, so that the operation efficiency is improved.
