Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an article supply device of a combination scale suitable for treating adherent articles such as shredded striped seasoned seaweed.

[0002]

[Prior art]

 Conventionally, there is no feeder suitable for this kind of article, and as a prior art for loosening and transporting articles as a feeder for articles that are soft, slender, and easily stagnant, as the prior art, there are actual developments 62-146929 and 64-64929. There are 8638.

[0003]

[Problems to be solved by the device]

 In the conventional method, even if the lumps are loosened, they are very lightly scattered by the wind and adhere to them again. Due to the large variation in the weight of one weighing tank, the quantification accuracy is poor even with a combination weigher. Has become. The reason for this is that the unevenness on the dispersion feeder cannot be maintained, there are clusters at one place, and there are few places at other places. As a result, there is a problem that the number that can be satisfied by the combination calculation is small, and as a result, the accuracy becomes poor. Therefore, it is an object of the present invention to provide a device for supplying articles to the dispersion feeder almost uniformly.

[0004]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention first installs a rotary stirring blade on the upper part of the central dispersion feeder with an adjustable interval along the inclined surface, and then installs the stirring blade on top of it. The conical dispersion that can adjust the interval of the conical dispersion is installed, and the drive unit is attached so that it can rotate as an integral structure with the stirring blade, and the articles dropped from the upstream transport feeder fall on the inclined surface of the conical dispersion. By arranging them, and then installing two level sensors on the left and right in the upper part near the outer circumference of the dispersion feeder, constantly monitoring the supply amount to the dispersion feeder and transmitting this signal to the drive unit, the layer thickness The conical dispersion and the stirring blade are configured to rotate toward the thinner side. Therefore, the conical dispersion and the stirring blade rotate left or right.

[0005]

[Action]

 According to the present invention configured as described above, the product conveyed from the upstream conveyance feeder is supplied to the dispersion feeder by the stirring blade while being distributed to the outside while hitting the inclined surface of the conical dispersion body. Therefore, the level sensors provided on the left and right sides detect the layer thickness of the articles on this dispersion feeder, and a signal is sent to the conical dispersion unit and the drive unit of the stirring blade, which are integrated, and rotate in the direction of thin layer thickness. Then, the articles are supplied so as to be substantially uniform. The articles that are almost uniformly supplied on the dispersion feeder are further supplied to the circularly arranged supply tanks by the linear feeders, the weights are measured by the weighing tanks, the combinations are selected, and the articles are discharged to the next stage.

【Example】

 An embodiment of the present invention is shown in FIGS. FIG. 1 is a diagram showing the configuration of a combination weigher including a supply device. In this figure, an article 3 such as seasoned seaweed is conveyed by a conveyor 1 and stored in a storage tank 2, and then a belt conveyor or a vibration conveyor is used. It is conveyed by the conveying feeder 4 onto the dispersion feeder 9 of the combination scale. The article 3 dropped from the tip of the transport feeder 4 hits the conical dispersion body 6, then hits the stirring blade 8 and is supplied onto the above-mentioned dispersion feeder 9, and is transferred by the linear feeder 11 arranged in a radial pattern. It is put into the arranged supply tanks 12. The articles 3 put into the supply tank 12 are sequentially supplied to a measuring tank 13 arranged below the weighing tank 13. The weight is detected by a load detector 14 such as a load cell connected to the measuring tank 13 and the weight is detected in a combination scale. After being selected as a combination equal to or close to the set weight by a built-in arithmetic unit (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 which the above-mentioned conical dispersion 6 is pierced and supported by a screw rod 7 connected to the drive unit 5. The screw rod 7 is provided with a screw in a fixed section, and the conical dispersion body 6 is locked at a predetermined position. The screw rod 7 can be moved up and down by loosening the lock and manually rotating the screw rod as a center. When the transport feeder 4 and the 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 dispersion feeder 9, and in the opposite case, The article 3 falls toward the center of the dispersion feeder 9. Therefore, the purpose of constructing the conical dispersion 6 is to adjust the position where the article 3 falls on the dispersion feeder 9. Next, the stirring blade 8 is fixed to the screw rod 7 like the conical dispersion 6, and the distance between the inclined upper surface of the dispersion feeder 9 and the inclined upper surface can be adjusted by loosening the lock nut like the conical dispersion. ing. Two level sensors 10a and 10b are installed on the left and right above the outer periphery of the dispersion feeder 9 to detect the layer thickness of the article 3 supplied to the dispersion feeder 9.

The stirring blade 8 is rotating at, for example, about 100 rpm, and when the article 3 falls on the stirring blade 8, the article hits the rotating blade, and when the article 3 is rotating in the clockwise direction, the feeding feeder 4 side. The articles are supplied while being dispersed to the left when viewed further. 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 integrally transmits them to the conical dispersion 6 and the drive unit 5 of the stirring blade 8, which causes reverse rotation. And the stirring blade 8 rotates counterclockwise. Then, the articles 3 start to be accumulated on the right side, and the level sensor 10a on the right side detects the layer thickness, changes the rotation direction, and rotates again in the clockwise direction. When the layer thickness detection value of both level sensors exceeds a certain value, the temporary rotation is stopped, but when either the left or right level sensor operates, the stirring blade rotates in the direction instructed and the above operation is repeated.

[0009]

[Effect of device]

 According to the article supply apparatus of the present invention, for example, seasoned seaweed and rubber bands can be stably and uniformly dispersed. Further, as a means for evenly dispersing, by adjusting the conical dispersion and the stirring blade up and down, and by appropriately selecting the driving rotation speed, it is possible to disperse almost uniformly even those with adhesiveness or those that are easily entangled. As a result, it is possible to supply each of the measuring tanks almost uniformly, so that the number of weighing layers that can participate in the combination calculation increases and the combination accuracy improves. Along with this, the effect of improving the processing capacity can be obtained.
