Description

The present invention relates to a powder supplying device and a powder dissolving device.

There is a known device that dissolves a powdered medicine (powdered drug) in water to produce a medicinal solution (see, for example, Patent Document 1). The device described in Patent Document 1 includes a hopper into which the medicine is poured, a dispersion and dissolution chamber in which the medicine poured into the hopper is dissolved in water, and a shutter that is disposed between the hopper and the dispersion and dissolution chamber and that adjusts the amount of medicine that falls from the hopper into the dispersion and dissolution chamber from zero to a maximum. The shutter is plate-shaped and has an adjustment port formed therethrough through which the medicine passes.

Publication No. 58-137428

However, with the device described in Patent Document 1, if you want to change the maximum amount of drug that can drop, you need to prepare multiple types of shutters with adjustment ports of different shapes and sizes. And every time you want to change the maximum amount of drug that can drop, you need to disassemble the device and replace the shutter with one that suits the desired maximum amount of drug that can drop. As a result, there is a problem in that the maximum amount of drug that can drop (maximum supply amount) cannot be changed quickly.

The device described in Patent Document 1 also has the problem that it is not possible to supply an accurate amount of drug to the dispersion and dissolution chamber depending on various conditions, such as the environment in which the device is used and the operating environment. Examples of such conditions include a device that is configured to be able to suck in the drug using the suction force of a suction pump in order to increase the speed at which the drug is supplied to the dispersion and dissolution chamber.

The object of the present invention is to provide a powder supplying device and a powder dissolving device that can supply an accurate amount of powder and can quickly change the amount of powder supplied.

One aspect of the powder supplying device of the present invention is a powder supplying device including a storage unit for storing powder to be consumed, and a flow path through which the powder flows down from the storage unit,
a first adjustment unit provided in the flow path and adjusting a primary supply amount of the powder from the storage unit to a downstream side;
and a second adjustment section provided downstream of the first adjustment section in the flow path and configured to adjust a secondary supply amount of the powder, adjusted to the primary supply amount, to the downstream side.

One embodiment of the powder dissolving apparatus of the present invention comprises:
A liquid supplying device that supplies a liquid capable of dissolving the powder;
The apparatus further includes a mixer that mixes the powder supplied from the powder supplying device and the liquid supplied from the liquid supplying device.

According to the present invention, first, the first adjustment unit adjusts the primary supply amount of powder. As a result, the powder adjusted to the primary supply amount flows down to the second adjustment unit. Next, the second adjustment unit adjusts the secondary supply amount of powder. By adjusting the supply amount in stages in this way, a precise amount of powder can be supplied downstream.
In addition, a configuration in which the primary supply amount is adjusted by a first adjustment unit on the upstream side and the secondary supply amount is adjusted by a second adjustment unit on the downstream side can change the powder supply amount more accurately and quickly than, for example, supply amount adjustment by only one of the first adjustment unit and the second adjustment unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A powder supplying device and a powder dissolving device according to the present invention will be described in detail below with reference to preferred embodiments shown in the accompanying drawings.
First Embodiment
A first embodiment of a powder supplying device and a powder dissolving device of the present invention will be described with reference to Figures 1 to 9. For convenience of explanation, the upper side in Figures 1, 2, and 5 to 9 will be referred to as "upper (or upper side)" and the lower side will be referred to as "lower (or lower side)".

The powder dissolving device 10 shown in Fig. 1 is a device for dissolving powder Q1 to be used in food (edible powder) in liquid Q2 to produce a solution Q3. The powder Q1 is not particularly limited, and examples thereof include skim milk powder, soybean powder, sugar, coloring agent, thickener, gelling agent, etc. The liquid Q2 is not particularly limited as long as it can dissolve the powder Q1, and examples thereof include water, etc.
This powder dissolving apparatus 10 includes a powder supplying device 1, a liquid supplying device 11, a confluence section 12, a mixing device 13, and a gas-liquid separating device 14. The configuration of each section will be described below.

The powder supplying device 1 is a device that supplies powder Q<b>1 toward a junction 12 .
The liquid supply device 11 is a device that supplies the liquid Q2 toward the confluence part 12.
The confluence section 12 is a portion where the powder Q1 supplied from the powder supplying device 1 and the liquid Q2 supplied from the liquid supplying device 11 join together.

The mixing device 13 is a device that applies suction force toward the junction 12 to the powder supplying device 1 and the liquid supplying device 11, and mixes the powder Q1 and liquid Q2 that have joined at the junction 12, i.e., dissolves the powder Q1 in the liquid Q2 to obtain a solution Q3. In addition, the suction force from the mixing device 13 allows the powder Q1 to be rapidly transported from the powder supplying device 1 to the junction 12, and the liquid Q2 to be rapidly transported from the liquid supplying device 11 to the junction 12. The configuration of the mixing device 13 is not particularly limited, but may be, for example, a configuration having a centrifugal pump.

The gas-liquid separator 14 is disposed on the discharge side of the mixer 13 and circulates the liquid Q2 containing undissolved powder Q1 to the mixer 13 via the circulation flow path 141, while discharging the solution Q3 that does not contain undissolved powder Q1 from the outlet 142.

In the powder dissolving device 10, it may be necessary to change the supply amount of the powder Q1 depending on, for example, the strength of the suction force of the mixer 13, the type of the powder Q1, etc. Even after the change, it is necessary to supply the powder Q1 at an accurate supply amount.
Therefore, the powder dissolving device 10 is configured to be able to quickly change the supply amount of the powder Q1 and to be able to supply the powder Q1 at an accurate supply amount even after the change. The configuration and operation of this device will be described below.

As shown in Figure 2 (as well as Figure 1), the powder supplying device 1 comprises a first storage section (storage section) 2, a housing 3, a first adjustment section 4, and a second adjustment section 5 having a second storage section (temporary storage section) 53.
The first storage section 2 is a hopper into which the powder Q1 is introduced and stored. The first storage section 2 is formed of a cylindrical body with openings in the upper and lower directions. The first storage section 2 is also funnel-shaped with an inner diameter that gradually decreases toward the bottom.

The housing 3 is disposed below the first storage section 2. The housing 3 has a housing main body 31 and a cover 32.
The housing body 31 is box-shaped and has an upper opening 311 that opens upward at the top.

The lid 32 is plate-shaped and is provided to cover the upper opening 311. The first storage section 2 is fixed to the upper side of the lid 32.
The lid 32 is also formed with a through hole 321 penetrating in the thickness direction, i.e., in the Z-axis direction. The through hole 321 is in communication with the first storage section 2. As a result, the powder Q1 passes through the first storage section 2, the through hole 321, and the upper opening 311 in this order, and falls. Note that the powder Q1 passes through a first adjustment section 4, which will be described later, between the through hole 321 and the upper opening 311.

As shown in Figures 3 and 4, in this embodiment, the shape of the through hole 321 in a plan view is a rectangle with a long side along the X-axis direction and a short side along the Y-axis direction, but is not limited to this. Other shapes may be, for example, a rectangle with a short side along the X-axis direction and a long side along the Y-axis direction, a rectangle such as a square, or a rounded shape such as a circle or an ellipse.

As shown in FIG. 2, an inclined surface 312 is formed on the inside of the bottom of the housing body 31. Furthermore, a side opening 313 that opens to the side is formed on the housing body 31 below the inclination direction of the inclined surface 312. Powder Q1 that falls from the upper opening 311 passes through the second adjustment section 5 described below, slides down the inclined surface 312, and is discharged from the side opening 313. Powder Q1 then flows into the confluence section 12.

In this way, in the powder supplying device 1, the area from the through hole 321 of the lid 32 to the side opening 313 of the housing body 31 functions as a flow path 33 through which the powder Q1 flows, that is, through which the powder Q1 passes. In this flow path 33, the powder Q1 flows down due to its own weight, and also flows down due to the suction of the mixer 13. The flow path 33 may include the first storage section 2, that is, the first storage section 2 may also constitute part of the flow path 33.

A first adjustment unit 4 and a second adjustment unit 5 are provided in the flow path 33 in this order from upstream to downstream.
The first adjustment unit 4 can adjust the primary supply amount S1 of the powder Q1 downstream before it reaches the second adjustment unit 5 from the first storage unit 2. The second adjustment unit 5 can adjust the secondary supply amount S2 of the powder Q1, which has been adjusted to the primary supply amount S1, downstream.

As shown in FIGS. 2 to 4, the first adjustment unit 4 has an opening degree changing member (plate member) 41 and a movement support member 42.
The opening change member 41 is a member that changes the opening of the flow path 33. Here, the "opening of the flow path 33" refers to the cross-sectional area of the portion of the flow path 33 through which the powder Q1 can pass. In this embodiment, it is the area of the portion of the through hole 321 through which the powder Q1 can pass in a plan view. In Figures 3 and 4 (similarly in Figure 10), it is the area of the hatched powder passing portion 322.

The opening degree change member 41 is composed of a plate member arranged parallel to the lid body 32. The opening degree change member 41 is arranged between the lower surface of the lid body 32 and a groove 314 formed along the Y-axis direction on the inside of the housing body 31. The groove 314 is formed on both sides of the opening degree change member 41 in the X-axis direction.
The opening degree change member 41 has one through hole 411 penetrating in the thickness direction thereof. The shape of the through hole 411 in plan view is a rectangle having a long side along the X-axis direction and a short side along the Y-axis direction, similar to the through hole 321 (see FIGS. 3 and 4). The area of the through hole 411 in plan view is the same as the area of the through hole 321 in plan view.

The moving support member 42 is a member that supports the opening degree change member 41 so that it can move along the Y axis direction relative to the cover body 32 (flow path 33). The moving support member 42 is arranged on both sides of the through hole 411 of the opening degree change member 41, i.e., on the positive side and negative side in the X axis direction. This allows the opening degree change member 41 to move stably. Note that in this embodiment, the moving support member 42 is arranged on both sides of the through hole 411, but this is not limited to this and it may be arranged on one side.

Each of the movable support members 42 is formed of a long plate member extending along the Y-axis direction, and abuts against the upper surface of the lid body 32. A long guide hole 421 extending along the Y-axis direction is formed penetrating through each of the movable support members 42 in the thickness direction. Two bolts (hexagon socket bolts) 43 are inserted into the guide hole 421 from above and screwed into the lid body 32.
Further, protrusions 422 that protrude toward the negative side in the Z-axis direction, i.e., downward, are formed on both ends of each of the movable support members 42. This allows each of the movable support members 42 to fix the opening degree change member 41 between the protrusions 422.

For example, in the state shown in FIG. 3, the entire through hole 321 of the lid body 32 and the entire through hole 411 of the opening degree change member 41 overlap. This maximizes the powder passing portion 322. Also, each bolt 43 is sufficiently tightened. This fixes the opening degree change member 41 to the lid body 32, and the state shown in FIG. 3 is maintained.

3 to the state shown in FIG. 4, each bolt 43 is loosened and the opening change member 41 is moved together with each moving support member 42 to the negative side in the Y-axis direction. At this time, the opening change member 41 can move smoothly because each bolt 43 is guided relatively to the guide hole 421. Then, the degree of overlap between the through hole 321 of the lid body 32 and the through hole 411 decreases by the amount that the opening change member 41 has moved, and the through hole 321 of the opening change member 41 is covered by the part (shutter part 412) where the through hole 411 is not present. This results in the state shown in FIG. 4. In this state shown in FIG. 4, the powder passing part 322 is smaller than the state shown in FIG. 3. In addition, by sufficiently tightening each bolt 43 again, the opening change member 41 is fixed to the lid body 32, and the state shown in FIG. 4 is maintained.

In this way, the powder supplying device 1 can regulate the maximum flow rate of powder Q1 passing through the powder passing portion 322 by the area (size) of the powder passing portion 322. For example, when the suction force of the mixer 13 is insufficient, the primary supply amount S1 is insufficient, and the maximum flow rate of powder Q1 can be increased as shown in FIG. 3. This can eliminate the insufficient state of the primary supply amount S1. On the other hand, when the suction force of the mixer 13 is excessive, the primary supply amount S1 is excessive, and the maximum flow rate of powder Q1 can be decreased as shown in FIG. 4. This can eliminate the excessive state of the primary supply amount S1.

As described above, the first adjustment unit 4 is configured to regulate the maximum flow rate of the powder Q1 as an adjustment of the primary supply amount S1. This maximum flow rate regulation can be achieved by the simple operation of moving the opening change member 41. This allows the primary supply amount S1 (supply amount) of the powder Q1 to be changed quickly. In addition, the downtime of the powder supply device 1 associated with changing the primary supply amount S1 can be minimized, thereby preventing a decrease in the operating rate of the powder supply device 1.

As shown in Figures 3 and 4, it is preferable that the opening change member 41 is provided with a finger hook 413 as close to the negative side of the Y axis as possible. A finger can be hooked on the finger hook 413 when moving the opening change member 41. This makes it easy to operate the opening change member 41. Therefore, for example, the position of the opening change member 41 can be easily changed without having to disassemble the powder supply device 1, change the position of the opening change member 41, and then reassemble it. Therefore, the configuration with the finger hook 413 contributes to speeding up the change of the primary supply amount S1.

The second adjustment unit 5 is provided downstream of the first adjustment unit 4 of the flow path 33. As described above, the second adjustment unit 5 is a part that adjusts the secondary supply amount S2 of the powder Q1, which has been adjusted to the primary supply amount S1, to the downstream side.
As shown in FIG. 2 , the second adjustment unit 5 has a rotor 51 and a drive unit 52 .

The rotor 51 has a shaft portion 511 , a flange portion 512 , and a blade portion 513 .
The shaft portion 511 is a cylindrical portion, and is supported by the housing body 31 of the housing 3 via a bearing 34 so as to be rotatable around the X axis.
The flange portion 512 is a portion whose outer diameter is larger than that of the shaft portion 511, and two flange portions 512 are disposed spaced apart in the X-axis direction.

The blade portions 513 are linearly arranged along the X-axis direction between the flange portions 512. As shown in Figures 5 to 9, a plurality of blade portions 513 are arranged radially.
The space surrounded by the shaft portion 511, the flange portions 512, and the adjacent blade portions 513 functions as a second storage portion 53 that stores the powder Q1 adjusted to the primary supply amount S1.

As described above, the shaft portion 511 is supported rotatably about the X-axis, and thus each second storage portion 53 is also supported rotatably about the X-axis. As a result, each second storage portion 53 can take at least two positions (states).
The first position (first position) is a position in which the second storage section 53 at its highest point (vertex) faces the upper opening 311. In this position, the powder Q1 that has fallen from the upper opening 311 is temporarily stored in the second storage section 53.

Changing the size of the powder-passable portion 322 is equivalent to changing the volume of the second storage portion 53. Changing the volume of the second storage portion 53 is difficult due to the configuration of the powder supplying device 1. Therefore, in this embodiment, by changing the size of the powder-passable portion 322, an effect similar to changing the volume of the second storage portion 53 is achieved.

In the second position (second position), the second storage section 53 is turned upside down at the lowest point. In this position, the powder Q1 stored in the first position falls from the second storage section 53 and is discharged. This allows the powder Q1 to be directed toward the junction 12.

The rotor 51 is connected to a drive unit 52, for example via a reducer. The drive unit 52 is a motor that rotates the rotor 51. The rotation speed of the rotor 51 (second storage section 53) can be changed by changing the voltage applied to the motor or the reduction ratio of the reducer. This variable rotation speed configuration allows the secondary supply amount S2 of powder Q1 to be quickly adjusted and changed.

For example, if the rotation speed increases, the number of times the second container 53 stores and discharges the powder Q1 per unit time increases, thereby increasing the secondary supply amount S2.
Conversely, if the rotation speed decreases, the number of times the second container 53 stores and discharges the powder Q1 per unit time decreases, so the secondary supply amount S2 also decreases.

Here, the pressure change in each second storage section 53 will be described with reference to Figs. 5 to 9. Note that in this embodiment, the total number of second storage sections 53 is eight, as an example, and the description will focus on one of these second storage sections 53 (hereinafter referred to as "second storage section 53A"). Also, the rotor 51 rotates clockwise. Also, "-" (minus) in each figure indicates a low pressure state (e.g., a vacuum state), and "+" (plus) indicates a high pressure state (e.g., atmospheric pressure or a pressure lower than atmospheric pressure but higher than the low pressure state).

Fig. 5: First state Fig. 5 shows the state after the powder Q1 is discharged from the second storage section 53A. When the powder Q1 is discharged, the second storage section 53A is subjected to a suction force from the side opening 313 (mixing device 13), and the second storage section 53A continues to rotate and is in a low pressure state.

FIG. 6: Second State In FIG. 6, the second storage section 53A is maintained in a low pressure state with communication between the side opening 313 and the upper opening 311 being cut off.

Fig. 7: Third state Fig. 7 shows the state where the second storage section 53A faces the upper opening 311, i.e., the first position. As a result, the second storage section 53A is opened to the upper opening 311, and the powder Q1 smoothly flows into the second storage section 53A due to the pressure difference between the two and the powder Q1 falling under its own weight. At this time, the second storage section 53A goes from a low-pressure state to a high-pressure state.

Figure 8: Fourth state In Figure 8, the second storage section 53A is again cut off from communication with the side opening 313 and the upper opening 311, and is maintained in a high-pressure state with powder Q1 stored therein.

Fig. 9: Fifth state Fig. 9 shows a state in which the second storage section 53A faces the side opening 313, i.e., the second position. At this time, the second storage section 53A is in a low-pressure state. In addition, in the second position, the powder Q1 is smoothly discharged from the second storage section 53A by the suction force from the side opening 313 and the powder Q1 falling under its own weight.

In the powder supplying device 1 configured as above, before the powder Q1 reaches the junction 12, the supply amount of the powder Q1 can be adjusted in stages.
That is, in the powder supplying device 1, first, the primary supply amount S1 of the powder Q1 is adjusted by the first adjustment unit 4. The primary supply amount S1 is adjusted by restricting the maximum flow rate of the powder Q1 by moving the opening degree change member 4. As a result, the powder Q1 is stored in each second storage unit 53 in a state where the maximum storage amount is restricted.

Next, the second adjustment unit 5 adjusts the secondary supply amount S2 of the powder Q1. This secondary supply amount S2 is adjusted by changing the rotation speed of the rotor 51 to adjust the amount of powder Q1 supplied to the junction 12 per unit time.

By adjusting the supply amount stepwise in this manner, a precise amount of powder Q1 can be supplied to the junction 12. This makes it possible to stably obtain the solution Q3 having a constant concentration of powder Q1.
It should be noted that when the supply amount is adjusted by only one of the first adjustment unit 4 and the second adjustment unit 5, there is a limit to how accurately the powder Q1 can be supplied.

In addition, the powder supplying device 1 can adjust the primary supply amount S1 with a simple configuration of moving the opening change member 4, and can adjust the secondary supply amount S2 with a simple configuration of changing the rotation speed of the rotor 51. This allows the supply amount of powder Q1 to the junction 12 to be changed quickly and easily, thereby preventing a decrease in the operating rate of the powder supplying device 1 when the supply amount of powder Q1 is changed.

Second Embodiment
Hereinafter, a second embodiment of the powder supplying device and powder dissolving device of the present invention will be described with reference to FIG. 10. The differences from the previously described embodiment will be mainly described, and descriptions of similar points will be omitted.
This embodiment is similar to the first embodiment, except that the configuration (shape) of the opening degree changing member of the first adjustment portion is different.

10, in this embodiment, the opening degree change member 41 of the first adjustment unit 4 has three through holes 411 arranged side by side along the Y axis direction. Hereinafter, these will be referred to as "through hole 411A", "through hole 411B", and "through hole 411C" in order from the positive side in the Y axis direction.
The shape of the through holes 411A to 411C in plan view is a rectangle having a long side along the X-axis direction and a short side along the Y-axis direction, and the long sides have the same length but the short sides have different lengths. As a result, the through holes 411A to 411C are different in size from one another. In this embodiment, the through hole 411A is the largest, the through hole 411C is the smallest, and the through hole 411B is an intermediate size between the through holes 411A and 411C. The area of the through hole 411A in plan view is the same as the area of the through hole 321 in plan view.

When the entire through hole 321 of the lid body 32 and the entire through hole 411A of the opening degree change member 41 overlap with each other, the powder passing portion 322 becomes maximum.
Furthermore, when the entire through hole 321 of the lid body 32 and the entire through hole 411C of the opening degree change member 41 overlap with each other, the powder passing portion 322 becomes smallest.
Furthermore, when the entire through hole 321 of the lid 32 and the entire through hole 411B of the opening degree change member 41 overlap (the state shown in FIG. 10), the powder passing portion 322 has an intermediate size.

In this way, by selecting through holes 411A to 411C, the size of powder passing portion 322 can be easily changed, and as a result, the maximum flow rate of powder Q1 can be regulated, i.e., the primary supply amount S1 can be quickly adjusted.
In this embodiment, the number of through holes 411 formed is three, but is not limited to this and may be two or four or more.

Third Embodiment
Hereinafter, a third embodiment of the powder supplying device and powder dissolving device of the present invention will be described with reference to FIG. 11. The differences from the previously described embodiment will be mainly described, and descriptions of similar points will be omitted.
This embodiment is similar to the first embodiment, except that the configuration (shape) of the rotor of the second adjustment unit is different.

As shown in FIG. 11 , in this embodiment, the rotor 51 of the second adjustment unit 5 has a shaft portion 511 , a spiral portion 514 , and a partition portion 515 .
The spiral portion 514 is formed to protrude from the outer periphery of the shaft portion 511. The spiral portion 514 is formed in a spiral shape around the X-axis. The number of the spiral portions 514 is two (two threads) in this embodiment, but is not limited to this and may be one or three or more.

The partition portion 515 is linearly installed along the X-axis direction between adjacent spiral portions 514 in the X-axis direction. The partition portions 515 are arranged at equal angular intervals around the X-axis, i.e., at equal intervals along the circumferential direction of the shaft portion 511.
The space surrounded by the shaft portion 511 , the spiral portions 514 , and the partition portions 515 adjacent to each other around the X-axis functions as the second storage portion 53 .
The rotor 51 having the above-mentioned configuration also makes it possible to adjust the secondary supply amount S2.

Although the powder supplying device and the powder dissolving device of the present invention have been described above with reference to the illustrated embodiments, the present invention is not limited thereto, and each part constituting the powder supplying device and the powder dissolving device can be replaced with any other part capable of exerting the same function. In addition, any other component can be added.
Furthermore, the powder supplying device and the powder dissolving device of the present invention may be a combination of any two or more of the configurations (features) of the above-described embodiments.

The number of first adjustment units 4 may be multiple, but it is preferable to have one as in each of the above embodiments. The reason for this is that, for example, even if multiple first adjustment units 4 are arranged, there is a risk that the action and effect of the first adjustment units 4 may not be improved as much as expected.

In addition, in each of the above embodiments, the opening degree change member 41 is supported so as to be movable along the Y-axis direction, but this is not limited thereto, and for example, it may be supported so as to be movable along the X-axis direction, or it may be supported so as to be rotatable around the Z-axis. Therefore, various displacement modes such as movement and rotation can be used for the support mode for the opening degree change member 41.

Further, although the number of second storage sections 53 arranged is plural in each of the above-described embodiments, the number may be one.
In addition, in the powder supplying device 1, the lengths in the X-axis direction of the through hole 321 of the lid body 32 that constitutes the flow path 33, the through hole 411 of the opening degree changing member, and the second storage section 53 may be redesigned depending on the application, i.e., they may be made longer or shorter than the state shown in Figure 1.
