Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration perspective view of a natto filling device. The filling device 1 has a shooter 2 arranged in an inclined shape, and this shooter 2 is formed in a gutter shape with an open top surface. In the example, the middle partition plate 3 is arranged along the longitudinal direction at the central portion, and two gutters are formed. The shooter 2 is vibrated intermittently in the front-rear direction by a vibration device. A shutter 4 that can be opened and closed in the vertical direction is arranged at the front end of the shooter 2, and the shutter 4 is vertically moved by an air cylinder 5.

A push-out plate 6 is arranged in the shooter 2 on the rear side of the shutter 4, and a slit 6a into which the partition plate 3 is loosely fitted is formed in the center of the push-out plate 6. ing. The push-out plate 6 is connected to a vertical cylinder 7 and a front-back cylinder 8, the push-up plate 6 is moved up and down by the operation of the vertical cylinder 7, and the push-up plate 6 is moved by the operation of the forward-back cylinder 8 to the shooter 2. Is moved back and forth along.

A screw-shaped scale adjustment dial 10 is provided at the upper end of the vertical cylinder 7, and the scale adjustment dial 10 is screwed into a support plate 9 to allow the push plate 6 to be pushed. Adjust the height of the rising end of this
Can be adjusted as appropriate. Further, a nozzle 11 is vertically arranged in the front part of the shutter 4, and a lower end part of the nozzle 11 is opened so that the nozzle 11
The tray 12 is disposed below the tray via a conveyor (not shown).

In such a structure, when the shutter 4 is lowered and the front end portion of the shooter 2 is closed, the push-out plate 6 is on the rear side close to the shutter 4 and the lower end portion thereof is the intermediate partition plate. It is arranged at a height position such that it is near the upper end of 3. When the shooter 2 vibrates in this state, the boiled bean-shaped natto placed on the shooter 2 moves to the front end side of the shooter 2 due to the vibration, and the natto comes into contact with the closed shutter 4. In this state, the push-out plate 6 is moved rearward by the front-rear air cylinder 8 with the lower end portion thereof being raised to the vicinity of the upper end of the partition plate 3, and when the pusher plate 6 is moved rearward, the pusher plate 6 is placed above the shooter 2. The upper side of the natto will be scraped back to the rear side.

After the push-out plate 6 has moved to a predetermined rear position, the push-up plate 6 is lowered by the operation of the vertical cylinder 7 until it comes into contact with the bottom surface side of the shooter 2. The push-out plate 6 stands by in this state, and when a tray (two trays in this example) 12 is moved below the nozzle 11 via a conveyor, the shutter 4 is moved upward by the operation of the air cylinder 5. It is opened, and at the same time, the push-out plate 6 is pushed toward the front end side of the shooter 2 by the operation of the front-rear cylinder 8. As a result, a certain amount of natto (fermented soybeans) on the front side of the shooter 2 enters the nozzle 11, drops into the lower tray 12 through the nozzle 11, and a predetermined amount of natto N is contained in the tray 12. Become. After the filling is completed, the tray 12 is moved via the conveyor, and the next empty tray 12 is arranged below the nozzle 11.

As described above, in this example, the natto which has been moved to the front end side of the shooter 2 is scraped back to the rear side by the push-out plate 6 so that the front end side of the shooter 2 is densely filled. Since the natto is present, the natto does not have a cavity and the weighing accuracy is improved as compared with the conventional one. In this state, the natto is surely pushed out to the nozzle 11 side by the extrusion plate 6, so that the extrusion plate 6 The natto is extruded in a state of being weighed for the extrusion distance of, and the natto can be reliably weighed without being affected by the fluidity due to a decrease in the temperature of the natto. In addition, since the natto is discharged by the extrusion plate 6 in each step, the shooter 2 and the like are not clogged with the soybean meal. The height of the extruded plate 6 when it is scraped back to the rear side can be appropriately adjusted by appropriately adjusting the amount adjustment dial 10, and the amount of natto to be scraped back can be adjusted accordingly.

In the present example, the vertical cylinder 7 and the front and rear cylinders 8 are arranged above the shooter 2 for the sake of explanation, but the vertical cylinder 7 and the front and rear cylinders 8 are located on the side of the shutter 2. The push-out plate 6 can be configured to be movable in the front-rear direction and the up-down direction by being disposed on the side. In this example, the natto N is filled in the two trays 12 and 12 at a time, but a device that can simultaneously fill four, six, or eight trays at a time. Can be realized by a similar structure.

[0013]

The natto filling device of the present invention comprises a gutter-shaped shooter for moving natto contained in the gutter into the front side by vibration, and a shutter provided at the front end of the shooter so as to be openable and closable. The shooter is configured so as to be provided with an extruding plate provided so as to be able to push the natto to the shutter side so as to be movable in the front-rear direction and the up-down direction, and a nozzle arranged in the front part of the shutter and dropping the natto downward. With this, the extruded plate can be moved backward at a predetermined height on the shooter to scrape back the natto, and the extruded plate can reliably discharge the natto to the nozzle side. It is possible to continuously perform good filling work without being affected by the temperature change of the soybean cake and without causing the clogging of the soybean meal etc., and the structure is simple and It has the effect of weighing errors can and that no device caused as.
