Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a powder transport device, and particularly to a powder transport device capable of transporting powder from below to above.

(Prior art and problems to be solved) Generally, when transporting powder or granules, if the powder or granules themselves are located above, it is relatively easy to transport them downward. However, on the other hand, it is extremely difficult to transport the powder and granules located at the bottom upwards, and the transport device used to do this is, for example, a spiral blade housed inside a cylinder. By rotating these blades, the powder or granules are conveyed from below to above, or a conveyor is used in a packet type.

However, when rotating spiral blades as described above, there is a need for lubrication due to the rotational movement, and there is a risk that metal wear particles may be generated due to the rotating contact between rigid bodies. Therefore, there is a risk that lubricant or metal abrasion powder may be mixed into the powder or granules, which poses a big hygiene problem, especially if the powder or granules are food.

Next, the operation of the device configured as described above will be explained.

First, when the drive source 5 is started, the connecting member 10 starts rotating clockwise in FIGS. 6 and 7 via the friction clutch 9.

In this case, the friction clutch 9 can only be driven in the range from the state shown in FIG. 6 to the state shown in FIG. 7 because the driven part can only rotate clockwise with respect to the driving part. The driven part rotates together with the part.

Therefore, between the state shown in FIG. 6 and the state shown in FIG. 7, the connecting rod 25 moves downward as the connecting member 1O rotates.

At this time, the shaft 24 rotatably attached to the connecting rod 25 passes through the U-shaped guide member 23 attached to one end of the conveying member 11, and the guide piece 26 provided at the end is fixed to the shaft 24. Since it is located within the regulating member 27 provided on the member 6, the conveying member 11 does not rise above the upper surface of the supporting member 1, but descends against the biasing force of the resilient member 34.

Since guide plates 22 are provided on both sides of the support member 1 when the transport member 11 is moved, there is no fear that the transport member 11 will come off the support member 1.

Then, when the conveying member 11 is lowered by the driving source 5 via the friction clutch 9 and reaches the state shown in FIG. You will be pulled upwards instantly.

When the conveyance member 11 reaches the desired upper position in this manner, the projection 35 provided on the lower surface of the conveying member 11 collides with the projection 36 provided on the upper surface of the support member l, so that the conveyance member 11 stops instantaneously. and is prevented from moving further upwards,
This completes the process, and this operation is repeated thereafter.

Therefore, when the above-mentioned operation is performed with the powder and granular material being charged into the inside of the input port 17, the powder and granular material located at the lowermost step 16 of the conveying member 11 will be When it is instantly pulled upward by the resilient member 34 and instantaneously stopped, it is flipped up and moved to the step 16 above the step 16 where it was initially located, and this operation is performed sequentially. After reaching the upper step, raise the cover 1 by climbing over the other end of the raising board 13.
2 reaches the discharge port 18 of the storage container 2 through the discharge port 18.
Located inside 1.

Therefore, by repeating the above-mentioned operation, the powder and granular material charged into the input port 17 is stored in the storage container 21 via the discharge port 18.

Moreover, during the above operation, the lifting plate 13 that lifts up the powder and granules is closed by the cover 12, so there is no fear that the powder or granules will scatter to the outside, and the conveying member Since there are no sliding contact parts inside the body 11, there is no risk of abrasion powder, such as metal powder, being mixed into the powder, making it extremely hygienic.

Furthermore, when the conveyance amount of the conveyance member 11 is small, the optimum conveyance amount can be achieved by rotating the turnbuckle 33 and adjusting the biasing force of the spring 32.

The installation inclination angle of the powder transport device is determined depending on the height position at which the powder transport device is to be transported and the space available for installation. This is to set the inclination angle of the inclined part and the vertical part.

In addition, in the above embodiment, the driving force of the driving source is transmitted through the friction clutch so that the conveying member is integrally driven only when it moves downward, and when the conveying member reaches the downward position, the transmission is canceled, and Although a structure has been described in which the spring moves instantly to the upper position by the urging force of the spring member, various mechanisms can be used without being limited to the combination of the friction clutch and the spring member. The conveying member, which is composed of an inclined part and a vertical part and is arranged to be inclined against the urging force of the urging member such as It is sufficient to instantaneously move it to the upper position to stir up the powder and granules.

[Effects of the Invention] By having the present invention configured as described above, the powder and granular material to be conveyed that is thrown into the inside of the conveyance member that is closed through the input port is tumbled up, and this splash At the time of lifting, the conveying member, which is arranged at an incline, is sequentially moved to the upper steps within the strip provided on the lifting plate, and is conveyed upward step by step, and after reaching the upper step, the conveying member It will fall through the outlet installed in the
