[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article feeder for a combination weigher suitable for treating sticky articles such as seasoned laver in the form of strips.

[0002]

2. Description of the Related Art Conventionally, there is no supply apparatus suitable for this kind of articles, and as a prior art for loosely transporting parts as a supply apparatus for articles which are soft, slender and easily stagnant,
There are Japanese Utility Model Laid-Open Nos. 62-146929 and 64-8638.

[0003]

In the conventional method, even if the lump is loosened, it is very lightly scattered by the wind and adheres again. Even though it is a scale, the quantification accuracy is poor. The cause is that the uniformity on the dispersion feeder cannot be maintained, and there are places that are gathered in one place, and there are few places in another place, resulting in `` unevenness '', and it is not possible to supply them to each measuring tank on average. The number that is satisfied by the combination operation is small,
As a result, there is a problem that accuracy is deteriorated. Therefore, an object of the present invention is to provide an apparatus for supplying articles to a dispersion feeder almost uniformly.

[0004]

In order to achieve the above object, the present invention first installs a rotary stirring blade above a central dispersion feeder at an adjustable interval along its inclined surface. A conical dispersion is provided thereon so that the distance between the agitating blade and the agitating blade can be adjusted, and a driving unit is attached so as to be able to rotate integrally with the agitating blade. It is arranged to drop on the inclined surface of the dispersion, and then two level sensors are installed at the upper part near the outer periphery of the dispersion feeder, and the amount of supply to the dispersion feeder is constantly monitored. By transmitting the light, the conical dispersion body and the stirring blade are configured to rotate toward the thinner layer. Therefore, the conical dispersion and the stirring blade rotate left or right.

[0005]

According to the present invention constructed as described above, the articles conveyed from the upstream conveying feeder are supplied to the dispersion feeder by the stirring blade while being slightly dispersed on the inclined surface of the conical dispersion body. Then, the layer thickness of the article on the dispersion feeder is detected by the level sensors provided on the left and right, and a signal is sent to the integrated cone disperser and the driving unit of the stirring blade, and the rotation is performed in a direction in which the layer thickness is reduced. Articles are supplied so as to be substantially uniform. The articles supplied almost uniformly on the dispersion feeder are further supplied to a supply tank arranged in a circle by a straight-ahead feeder, weighed in a weighing tank, selected in combination, and discharged to the next stage.

[0006]

1 and 2 show an embodiment of the present invention. FIG. 1 is a view showing a configuration of a combination weigher including a supply device. In this figure, after a product 3 such as finely seasoned laver is conveyed by a conveyor 1 and stored in a storage tank 2, a belt conveyor or a vibration conveyor is used. The conveyer feeder 4 conveys it onto the dispersion feeder 9 of the combination weigher. The article 3 dropped from the tip of the transport feeder 4 hits the conical dispersion member 6 and then is supplied to the dispersion feeder 9 by hitting the stirring blade 8 and is transferred by a linearly arranged feeder 11 arranged radially and arranged in a circular form from the tip. Is supplied to the supply tank 12. The articles 3 put into the supply tank 12 are sequentially supplied to a weighing tank 13 disposed below the supply tank 12, and the weight is detected by a load detector 14 composed of, for example, a load cell connected to the weighing tank 13, and is incorporated in the combination weigher. After being selected as a combination equal to or close to the set weight by the calculated calculator (not shown), it is discharged to the collecting chute 15.

FIG. 2 is a perspective view showing a main part of the present invention. In this figure, the above-mentioned conical dispersion member 6 is supported by a threaded rod 7 connected to the driving part 5. The threaded rod 7 is provided with a thread for a certain section, and the conical dispersion member 6 is locked in a predetermined position. The thread can be lifted and lowered by loosening the lock and rotating the threaded rod by hand. When the above-mentioned transport feeder 4 and the above-mentioned conical dispersion body 6 are close to each other (the conical dispersion body 6 is at a high position), the article 3 falls near the circumference of the above-mentioned dispersion feeder 9. Is the distributed feeder 9
Fall near the center of The purpose of the construction of the cone dispersion 6 is therefore to adjust the position at which the article 3 falls on the dispersion feeder 9. Next, the stirring blade 8 is fixed to the screw rod 7 in the same manner as the cone dispersion 6, and the distance between the stirring blade 8 and the inclined upper surface of the dispersion feeder 9 can be adjusted by loosening the lock nut similarly to the cone dispersion. I have. Two level sensors 10a are provided on the left and right at the upper part near the outer periphery of the dispersion feeder 9,
10 b is installed and detects the layer thickness of the article 3 supplied to the dispersion feeder 9.

The stirring blade 8 rotates at, for example, about 100 rpm. When the article 3 falls on the stirring blade 8, the article hits the rotating blade. When the article 3 rotates clockwise, it is viewed from the transport feeder 4 side. The goods are supplied while being dispersed to the left. Then, when the articles are accumulated on the left side, the level sensor 10b on the left side detects the layer thickness of the articles and transmits them to the driving part 5 of the conical dispersion member 6 and the stirring blade 8 which are rotating together and rotates in reverse. Switching, the stirring blade 8 rotates counterclockwise. Then, the goods 3 begin to accumulate on the right side,
The right level sensor 10a detects the layer thickness, changes the rotation direction, and rotates clockwise again. When the layer thickness detection values of both the level sensors become equal to or more than a certain value, the temporary rotation is stopped. However, when one of the left and right level sensors is operated, the stirring blade rotates in the direction instructed, and the above operation is repeated.

[0009]

According to the article supply apparatus of the present invention, for example, finely seasoned laver and rubber bands can be stably and uniformly dispersed. In addition, as a means for average dispersion, the conical dispersion and the stirring blade are adjusted by moving the stirring blade up and down, and by appropriately selecting the driving speed, even those having adhesion or easily entangled can be substantially uniformly dispersed. Therefore, almost uniform supply to each measuring tank becomes possible, so that the number of measuring layers that can participate in the combination calculation increases, and the combination accuracy improves. With this, the effect that the processing capacity is improved can be obtained.
