Description

[Detailed Description of the Invention] The present invention relates to a quantitative feeding device for powder, and particularly to a quantitative feeding device suitable for use with powder that easily absorbs moisture, such as powder for carbonated beverages.

Conventionally, caps of carbonated beverage containers containing powder for carbonated beverages have been commercially available.

In this case, in order to pack the powder into the cap, a rotating plate with a powder storage hole is installed at the bottom of the powder storage hopper, and a sliding part integrated with the hopper is installed on the rotating plate. As a result, the powder in the hopper is packed into the powder storage hole by this sliding part, and a blind plate with a cutout in a part is installed on the underside of the rotary plate to accommodate the powder. This was done using a device configured to drop powder and supply it when the hole was located in this notch.

However, with such a configuration, the powder is not necessarily sufficiently stored in the powder storage hole, it is difficult to drop and supply the powder if the powder gets even slightly wet, and the powder is only one type of powder. The deficiencies such as being unable to supply only 100% of the total amount were not resolved.

The present invention was proposed in view of the above-mentioned drawbacks of the conventional methods, and is capable of reliably supplying a predetermined amount of powder without forming a bridge even when the powder is impregnated with moisture. The object of the present invention is to provide a powder quantitative supply device that can continuously supply many types of powder with the same device.

Embodiments of the present invention will be described below based on the drawings.

In FIGS. 1 and 3, reference numeral 1 denotes a hopper made of a transparent cylindrical shape for storing powder, and an upper end opening 1a into which the powder is introduced is closed with a lid 2.

This hopper 1 is configured to rotate at a low speed at a predetermined speed by driving a rotating shaft 3 attached to the center thereof by a drive motor (not shown) equipped with a reduction gear.

Further, the inside of the hopper 1 is divided into a plurality of chambers (three chambers in the figure) by supporting a plurality of partition plates 4 on a central cylinder 5.

On the other hand, the bottom surface of the hopper 1 has a plurality of circular powder outlet holes 6 at equal intervals on its outer circumference. ...is open.

Immediately above each powder outflow hole 6, a powder stirring blade 7 is arranged respectively.The stirring blade 7 here has a shaft 8 directly connected to the stirring blade 7, which is connected to an annular bearing 9 provided on the inner wall surface of the hopper 1.
It penetrates the wall surface and protrudes to the outside, and a pinion 1 is attached to the tip of the pinion.
0 are directly connected to each other.

Each pinion 10 approaches a rack 11 that is fixed to an external body such as a support frame (not shown) without rotating in a part of the outer part of the hopper 1, and rotates while meshing with the rack 11. This allows the stirring blade 7 to be temporarily rotated.

A cam ring 12 is arranged directly below the hopper 1.
This cam ring 12 does not rotate and is fixed like the rack.

As shown in FIG. 3, the cam ring has an enlarged-diameter stepped portion 14 formed by vertically cutting out a portion of the inner wall surface 13, and this stepped portion 14 gradually connects to the inner wall surface 13 as a slope 14a.

Then, the disc 15 is fitted into the cam ring 12,
The disc 15 is pivotally attached to the rotating shaft 3.

Slot holes 16 are formed in the disc 15 in radial directions from the central axis in correspondence with the outflow holes 6 of the hopper 1, and the slots 16 reach the outer peripheral end of the disc 15.

A sliding piece 17 is accommodated in each slot 16, and a quantitative supply hole 18 that penetrates vertically is opened in the middle of this piece 17.

Each sliding piece 17 is biased toward the cam ring 12 by the elastic force of a compression spring 19 interposed between a recess 17a at its rear end and a recess 15a of the disc 15.

The sliding pieces 17 are held by a support ring 20 supported on the disk 15, and each sliding piece 17 is attached to this ring 20.
A powder falling hole 21 is provided corresponding to each of the holes.

That is, among the sliding pieces 17, the fixed quantity supply hole 18 of the sliding piece 17, whose spring 19 is compressed and is urged against the inner wall surface 13 of the cam ring 12, is connected to the outflow hole of the hopper 1 as shown in FIG. 6, and the sliding piece 17 is urged to collide with the enlarged diameter stepped portion 14 of the cam ring 12.
The metering supply hole 18 is connected to the support ring 20 as shown in FIG.
It is arranged and configured so as to coincide with the drop hole 21 of.

Note that 22 is a container that accommodates the powder discharged from the drop hole 21.

Next, the operation of the present invention will be explained.

In order to make the explanation easier to understand, the sliding piece 17 falls into the enlarged diameter stepped portion 14 of the cam ring 12, and the fixed amount supply hole 18
The movement after the powder inside is discharged from the drop hole 21 of the support ring 20 will be explained.

After the powder is discharged, the sliding piece 17 passes through the slope 14a of the cam ring 12 as the hopper 1 rotates, and the spring 19
When the sliding piece 17 is pushed back against the elastic force of the cam ring 12 and eventually reaches the inner wall surface 13 of the cam ring 12, as shown in FIG.
The metering supply hole 18 of the hopper 1 coincides with the outflow hole 6 of the hopper 1.

Here, the powder in the hopper 1 is accommodated into the quantitative supply hole 18 through the outlet hole 6, but in order to more reliably accommodate the powder, a pinion 10 corresponding to the outlet hole 6 is provided. When the powder passes through the rack 11, the stirring blade 7 is rotated to stir the powder around the outflow hole 7, thereby preventing the occurrence of powder bridging at the outflow hole 7, and at the same time sending the powder into the outflow hole. Thus, the powder can be reliably accommodated in the quantitative supply hole 18.

Thus, the sliding piece 17 is connected to the enlarged diameter stepped portion 14 of the cam ring 12.
At the same time, as shown in FIG. The powder passes through the drop hole 21 and is stored in the container 22.

In this way, while the hopper 1 is rotating, the above operation is performed continuously for each sliding piece 17.

Incidentally, the container 22 shown by the imaginary line is applied to the drop hole 21 by an automatic means (not shown) a little before the sliding piece 17 falls into the enlarged diameter stepped portion 14, as shown in FIG.
After the powder is accommodated, it leaves the drop hole 21 and is sent to another process.

For example, when the container 22 is a cap for liquid juice, the powder stored in the cap 22 is carbonated beverage powder made of granulated baking soda, granulated citric acid, natural coloring, etc.
As shown in the figure, the cap 22 containing the powder is screwed onto the mouthpiece 24 of the container body 23 containing the liquid juice.
Liquid juice and carbonated powder are separated and used as juice for sale.

When the juice is deeply screwed into the cap 22 and the protrusion 25 in the cap breaks through the thin film 26 at the top of the mouthpiece 24, carbonic acid powder is mixed into the liquid juice and can be drunk as carbonated water.

27 is a liquid juice inlet.

In addition, by dividing the inside of the hopper 1 with the partition plate 4, if powder is stored in each compartment by color, for example,
Many types of powder can be continuously stored in the cap.

Further, the partition plate 4 may partition each outflow hole 6 one by one.

As described above, according to the present invention, by providing the stirring blade directly above the powder outlet hole of the hopper, even powder that is easily impregnated with moisture can be rubbed without creating a bridge around the outlet hole. Powder can be reliably dropped into the quantitative supply hole of the moving piece.

In addition, the powder is supplied from the quantitative supply hole of the sliding piece by utilizing the impact force when the sliding piece falls into the enlarged diameter step part of the cam ring, so the powder can be reliably discharged and the powder can be reliably fed at a constant rate. There are effects such as being able to supply
