Description

The present invention relates to a powder vibration transport device that transports powder such as powder by vibration, and particularly to a powder vibration transport device that uses a piezoelectric vibration element. It also relates to a powder packaging machine using such a powder vibration transport device.

In powder packaging machines used for automating the dispensing work of medicines, especially powders, powder transport devices using vibration by electromagnets have been used so far, and in recent years, small amplitude and high frequency have been used. Since the vibration noise is small, a powder transport device using vibration by a piezoelectric element has been put into practical use.

In the electromagnet type, one direction of vibration is due to the force of the electromagnet, but the other direction is reciprocating motion due to the spring system of the mechanism, which causes a problem that variation occurs for each device. However, in the piezoelectric element type, the bimorph structure has the advantage that the reciprocating motion is stabilized by the force generated by the piezoelectric element in both reciprocating and reciprocating.

For example, in Patent Document 1, a powder feeder for transporting powder on a trough by vibrating two sets of piezoelectric elements provided below the trough on which the powder is placed, and a drug distribution device using the same. The technical idea of is disclosed.

FIG. 9 is a side view of a conventional powder vibration transport device, and will be described including contents not disclosed in Patent Document 1.

The powder vibration transport device 90 includes a substantially flat plate-shaped shaking table 91 on which powder transported by vibration is placed, and two piezoelectric vibration units 92a provided between the shaking table 91 and the base 94. It has 92b and.

The lower ends of the two piezoelectric vibrating portions 92a and 92b are attached to the mounting projections 941a and 941b of the base 94, respectively, and the upper ends thereof are attached to the mounting projections 911a and 911b of the shaking table 91, respectively.

The angles R formed by the piezoelectric vibrating portions 92a and 92b with the base 94 are almost equal to 90 degrees or less. As a result, the base 94, the piezoelectric vibrating portions 92a and 92b, and the shaking base 91 are configured to form a parallelogram.

Further, the piezoelectric vibration portions 92a and 92b are composed of bimorph piezoelectric elements 921a and 921b and amplification springs 922a and 922b, and the bending vibration generated by driving the bimorph piezoelectric elements 921a and 921b is the amplitude of the amplification springs 922a and 922b. Is amplified.

This amplified vibration is transmitted to the shaking table 91 as vibration for laying down or standing the parallelogram, and as a result, the pile of powder P1 contained in the trough container 95 coupled to the pedestal 91 is further broken. As a powder layer like P2, the powder can be transported to the discharge port 951 of the trough 95 and dropped in the direction of the arrow.

However, since the piezoelectric vibrating portions 92a and 92b are composed of the bimorph piezoelectric elements 921a and 921b and the amplification springs 922a and 922b, their lengths are long, and the height T9 from the base 94 to the shaking table 91 is increased. growing.

As a result, the height between the discharge port 951 at which the powder is discharged from the trough 95 and the saucer for receiving the powder (for example, the saucer portion 712 described later) is increased, whereby the saucer for the powder is increased. There is a problem that it is scattered to the outside.

Further, there is a problem that two sets of piezoelectric elements are used and the cost is high.

Japanese Unexamined Patent Publication No. 11-180528

In view of the above problems, the problem to be solved is low-cost powder that can reduce the scattering of powder falling from the powder discharge port and can accurately measure the amount of powder discharged. It is an object of the present invention to provide a vibration transport device and a powder packaging machine using such a powder vibration transport device.

In order to solve the above problems, the present invention is a powder vibration transport device.
-A substantially flat plate-shaped shaking table on which powder transported by vibration is placed,
-A support that connects one end of the shaking table to the lower front side in the powder transport direction,
-On the rear upper side of the shaking table in the powder transport direction, a piezoelectric vibrating part that connects one end thereof,
-It is characterized by having a base that is coupled to the other end of the support and is also coupled to the other end of the piezoelectric vibrating portion.

Here, preferably, the base has an L-shaped shape having a substantially horizontal flat plate-shaped portion and a substantially vertical flat plate-shaped portion, and the other end of the support is coupled to the substantially horizontal flat plate-shaped portion. The other end of the piezoelectric vibrating portion is coupled to the substantially vertical flat plate-shaped portion.

The substantially horizontal flat plate-shaped portion and the substantially vertical flat plate-shaped portion may be integrally formed, or may be formed of different members and connected by a screw or the like to be integrated.

Further, the structure is not limited to a flat plate shape, and any structure may be used as long as it can hold both the other end of the support and the other end of the piezoelectric vibrating portion.

Further, the support is configured so that the shaking table and the base can be moved within a predetermined range. For example, both ends of the support are fixedly coupled to the shaking table and the base but contain an elastic body, or the support is a rigid body but both ends are rotatably connected to the shaking table and the base. The configuration is such that

In this way, the height from the discharge port of the powder transported by the vibrating body to the substantially horizontal plate-shaped portion of the base is higher than the case where the piezoelectric vibrating part is provided under the shaking table as in the conventional case. Can be reduced.

That is, the piezoelectric vibrating part needs to have a predetermined vertical height in order to obtain the required vibration performance, but since the support has few such restrictions, the vertical height of the support is piezoelectric. It can be made smaller than the vertical height of the vibrating part.

By doing so, for example, when the powder saucer is installed at the height of a flat plate-like portion substantially horizontal to the base, the distance (free fall height) from the powder discharge port to the saucer becomes small. Therefore, it is possible to prevent troubles due to powder scattering and the like.

Further, by reducing the number of piezoelectric vibrating parts from the conventional two to one, the effect of cost reduction is also great.

Further, in the powder vibration transport device of the present invention, both the piezoelectric vibration portion and the support are such that the lower end is in the front in the powder transport direction and the upper end is in the rear in the powder transport direction. The stretching direction may be substantially parallel, or the piezoelectric vibrating portion may be more gently inclined than parallel.

In this way, the powder is transported in the powder transport direction at high speed and smoothly.

Further, the present invention may be characterized in that it is a powder vibration transport device, and further has a weight measuring unit for measuring all the weights on the base.

By doing so, the amount of powder released can be accurately measured.

Further, the present invention has the powder vibration transport device and a rotary disk having a saucer portion having a concave cross section on the outer peripheral portion, which receives the powder discharged from the powder vibration transport device, and the powder. It may be an embodiment of the powder vibration transport device with a rotating disk, characterized in that the saucer portion is arranged directly below the powder discharge port of the body vibration transport device.

By doing so, the released powder can be placed uniformly (equally density) or with different densities on the rotating disk so as to be suitable for the subsequent processing, which is extremely effective in practical use. Is high.

Further, the present invention is an embodiment in which the powder vibration transport device is a powder release device, and has a powder release device and a powder packaging device for packaging the powder released from the powder release device. You may.

By doing so, it is possible to realize a powder packaging machine in which the powder can be transported smoothly, the powder can be measured accurately, and troubles such as scattering of the powder to the outside do not occur.

According to the powder vibration transport device and the powder packaging machine using the powder vibration transport device as the powder discharge device of the present invention, the piezoelectric vibration unit is installed at one place and above the shaking table. Since the drop distance to the saucer after the powder is discharged can be reduced, it is possible to provide a powder vibration transport device with a simple structure, no trouble such as scattering of the powder to the outside, and a low cost. can do.

Further, by incorporating a weight measuring unit into such a powder vibration transport device, it is possible to provide a powder vibration transport device capable of accurately measuring the amount of powder released, and further, such powder vibration transport device. By using the device as a powder release device, it is possible to provide a powder packing machine having these advantages.

FIG. 1 is a side view of a powder vibration transport device according to an embodiment of the present invention.

The powder vibration transport device 10 has a substantially flat plate-shaped shaking table 11 on which powder transported by vibration is placed, and a support 12 having one end bonded to the front lower side of the shaking table 11 in the powder transport direction. And, on the rear upper side of the shaking table in the powder transport direction, the piezoelectric vibrating portion 13 to which one end thereof is coupled and the base 14 to be coupled to the other end of the support 12 and also to the other end of the piezoelectric vibrating portion 13. And have.

On the upper surface of the shaking table 11, a gutter-shaped trough 15 containing powder and having one end and an upper portion of a horizontal portion open is detachably installed.

The powder transport direction is a direction toward the end of the open horizontal portion (from right to left in FIG. 1), and the end thereof is the powder discharge port 151.

The trough 15 may be fixed rather than removable, and may be in the form of a removable storage container in which a rectangular parallelepiped other than the discharge port is closed instead of the trough 15.

Further, the shaking table 11 may have a minute inclination, unevenness, protrusions on the floor surface, or the like as long as it has a substantially horizontal plate shape.

The base 14 has an L-shaped cross section having a substantially horizontal flat plate-shaped portion 141 and a substantially vertical flat plate-shaped portion 142.

The support 12 is formed of an elastic thin plate, and one end thereof is fixed to the support mounting portion 111 below the front (tip portion) in the powder transport direction of the shaking table 11 with screws, and the support 12 is formed of the base 14. The other ends are fixed to the support mounting portion 142 of the substantially horizontal plate-shaped portion 141 with screws.

The mounting direction of the support 12 is such that the lower end thereof is in front of the powder transporting direction and the upper end thereof is rearward in the powder transporting direction, and the mounting angle thereof is tilted by about 20 degrees with respect to the vertical direction. The mounting angle is not limited to this value.

Here, the total length of the support 12 is shorter than the total length of the piezoelectric vibrating portion 13 described later.

The piezoelectric vibration unit 13 fixes a piezoelectric vibration element 131 that generates piezoelectric vibration and an amplification spring 132 that amplifies the generated vibration in series with a screw.

In the piezoelectric vibrating portion 13, one end of the amplification spring (one end of the piezoelectric vibrating portion) is fixed to the piezoelectric vibrating portion mounting portion 131 below the rear (rear end portion) of the shaking table 11 in the powder transport direction. One end of the piezoelectric element 131 (the other end of the piezoelectric vibrating portion 13) is fixed to the piezoelectric vibrating portion mounting portion 143 of the substantially vertical plate-shaped portion 142 of the base 14 with a screw.

The mounting direction of the piezoelectric vibrating portion 13 is such that the lower end thereof is in front of the powder transporting direction and the upper end thereof is rearward in the powder transporting direction, and the mounting angle is tilted by about 20 degrees with respect to the vertical direction. .. The mounting angle is not limited to this value.

That is, since the piezoelectric vibrating portion 13 and the support 12 are attached in a substantially parallel state and the total length of the support 12 is shorter than the total length of the piezoelectric vibrating portion 13, both ends of the piezoelectric vibrating portion 13 The vertical height between both ends of the support 12 is smaller than the vertical height between the two.

FIG. 2 is a cross-sectional view showing the structure of the piezoelectric element 131 according to the embodiment of the present invention.

The piezoelectric element 131 has a bimorph structure in which plate-shaped piezoelectric bodies 133a and 133b made of a piezoelectric material such as lead zirconate titanate are bonded to both surfaces of a conductive substrate (iron plate) 132. In this configuration, the conductive substrate (iron plate) 132 is grounded 134, and the piezoelectric drive circuit 135 generates an alternating current to conduct the plate-shaped piezoelectric bodies 133a and 133b to the surface side, for example, 133a. When the side extends in the plane direction and the 133b side contracts in the plane direction, the deformation of the arrow occurs, and when the currents alternate, the reverse deformation occurs, and by continuing this, reciprocating vibration is obtained.

The material and structure of the piezoelectric element 131 are not limited to this example, and may be a monomorph structure, for example, due to the circumstances of the overall configuration.

Next, FIG. 3 is a side view of the powder vibration transport device including the weight measuring unit according to the embodiment of the present invention, and all the weights on the base 14 below the powder vibration transport device shown in FIG. It is equipped with a weight measuring unit that can measure.

The weight measuring unit 16 is composed of a substantially horizontal plate-shaped measuring table 161 and a load cell 162, and a movable end (measurement end) 163 of the load cell 162 is fixed to the lower side of the substantially horizontal plate-shaped portion 141 of the base 14, one of the following. , The fixed end 164 of the load cell 162 is fixed to the upper side of the measuring table 161.

Next, the operation of the powder vibration transport device having such a configuration will be described.

First, the trough 15 containing the powder is fixed to the shaking table 11.

Next, an alternating current is applied to the piezoelectric drive circuit 135. Then, the piezoelectric element 131 vibrates the shaking table 11 diagonally upward in the powder transport direction (left direction in the figure) and in the opposite direction, and the amplification spring 132 amplifies the vibration, breaking the powder pile and breaking the powder. The body is gradually transported toward the discharge port 151 of the trough 15, and is discharged outward (downward) from the discharge port 151.

Here, the support 12 is responsible for supporting the shaking table 11 and smooth vibration of the piezoelectric vibrating portion 13. That is, by appropriately setting the spring constant and the length of the support 12, the vibration table 11 can be kept substantially horizontal and vibrated diagonally upward and diagonally downward without hindering the movement of the piezoelectric vibrating portion 13. ..

FIG. 4 is an explanatory diagram illustrating the amplitudes of the front end side and the rear end side of the shaking table in some embodiments of the present invention, and as shown in FIG. 4A, in the case of this embodiment, it is supported. The body 12 and the piezoelectric vibrating portion 13 are parallel to each other, and the angle R1 formed by the support 12 and the angle R2 formed by the piezoelectric vibrating portion 13 with respect to the shaking table 11 are substantially equal and smaller than 90 degrees. The amount of sinking of the shaking table 11 generated by the deformation of each of the support 12 and the amplification spring 132 of the piezoelectric vibration unit 13 is S1 at the position (front end side) of the support 12 and the piezoelectric vibration unit 13. Since S2 is obtained at the position (rear end side) and S1> S2, the amplitude is larger on the tip side instead of horizontal subduction, but when the subduction amount is small, it is practically. It is a subduction that is close to horizontal, and practical vibration transportation is possible.

Here, comparing the powder vibration transport device 10 of the embodiment of the present invention shown in FIG. 1 with the conventional powder vibration transport device 90 shown in FIG. 9, FIG. 1 shows the powder vibration transport device 10. At the height T1 at which the powder discharged from the discharge port 151 falls to a saucer provided at substantially the same height as the base 14 (for example, the saucer portion 712 described later), and at the same height T9 shown in FIG. , T1 is significantly smaller, and therefore, troubles such as powder scattering during this period are less likely to occur.

The operation when the powder vibration transport device 10 includes the weight measuring unit 16 will be described. The load cell 162 fixed on the measuring table 161 can measure the weights of the shaking table 11 and all the members and powders above the shaking table 11 via the movable end 163.

Therefore, the weight of the released powder is precisely measured as the weight reduced by the load cell 162 of the weight measuring unit 16, and when the desired weight is released, the energization of the piezoelectric element 131 is stopped.

Here, the powder vibration transport device 10 including the weight measuring unit of one embodiment of the present invention shown in FIG. 3 and the conventional powder vibration transport device 90 shown in FIG. 10 have a weight measuring unit 96 (the embodiment of the present invention). The powder discharged from the discharge port 151 of the powder vibration transport device 10 is almost the same as that of the measuring table 161 in FIG. At a height T3 that drops to a saucer provided at the same height (for example, a saucer portion 712 described later) and a similar height T10 shown in FIG. 10, T3 is significantly smaller, and therefore the powder during this period. The occurrence of troubles such as scattering is reduced.

Regarding the weight measuring unit 16, the configuration described so far is suitable as the powder vibration transport device 10, but it is not necessarily such a configuration and is a measuring unit that directly measures the released powder. However, it may be effective from the overall configuration.

Further, here, the powder vibration transport device 10 is further provided with a vibration isolator (not shown) having a vibration absorbing element such as a spring or an elastic body between the base 14 and the weight measuring unit 16. You may. The influence of the vibration of the shaking table 11 on the measured value can be reduced.

Next, another embodiment of the present invention will be described.

FIG. 5 is a front view (with some omissions) showing an embodiment of the powder packaging machine of the present invention, and FIG. 6 is a part of the powder packaging machine of the embodiment of the powder packaging machine of the present invention. It is a top view which shows.

The powder packaging machine 50 includes a powder discharging device 60 that discharges powder using the powder vibration transporting device 10 described so far, and a powder packaging device 70 that packages the released powder.

The powder discharge device 60 has the same configuration as the powder vibration transport device 10, and has a substantially flat plate-shaped shaking table 11 on which powder (powder) transported by vibration is placed and a powder (powder) transport of the shaking table 11. On the front lower side in the direction, a support 12 that connects one end thereof, on the rear upper side in the powder (powder) transport direction of the shaking table, a piezoelectric vibrating portion 13 that connects one end thereof, and the other end of the support 12. It has a base 14 that is coupled and is also coupled to the other end of the piezoelectric vibrating portion 13.

The powder packaging device 70 receives and distributes the powder discharged from the powder discharge device 60 by the tray portion 712 having a concave surface having an arcuate cross section in the vicinity of the outer periphery of the rotary disk 711, and from the disk distribution unit 71 and the disk distribution unit 71. A powder scraping disc portion 72 provided with a disc 721 for scraping powder at the tip portion, a hopper chute 73 for dropping the powder scraped from the powder scraping disc portion 72 downward, and a packing paper at the outlet of the hopper chute 73. It has a powder packaging unit 74 for arranging and packaging the powder in the packaging paper.

Here, the saucer portion 712 is arranged directly below the discharge port 151 of the trough 15 mounted on the shaking table 11, and its height (position) is substantially the same as the base 14 of the powder discharge device 60. Is normal.

The rotary disk 711 of each disk distribution unit 71 is installed substantially horizontally and is rotatably driven by a stepping motor 714 via a gear 713.

The circumferential diameter of the disc 721 at the tip of the powder scraping disc portion 72 is the same as the diameter of the arcuate concave surface of the saucer portion 712, and is rotatable by the motor 722.

Further, the powder scraping disk portion 72 has its rear end rotatably supported by a shaft 723, and can be retracted upward when the powder scraping operation is not performed.

In one embodiment of the present invention, one powder packaging device 70 is provided with two sets of a powder discharge device 60, a disk distribution unit 71, and a powder scraping disk unit 72, respectively, and a hopper chute 73 and a hopper chute 73. The powder packaging unit 74 is provided with a common set for these two sets.

Next, the operation of the powder packaging machine will be described.

The powder discharged from the discharge port 151 by driving the shaking table 11 of the powder discharge device 60 continuously rotates the stepping motor 714, so that the saucer portion of the arcuate concave surface of the rotating disk 711 of the disk distribution unit 71 It can fall to 712 to form a donut-shaped pile of powder P1 in a circumferential shape. This operation is called "circumferential sprinkling operation".

At this time, the disc 721 of the scraped disc portion 72 rotates upward around the shaft 723 and does not interfere with the circumferential sprinkling operation of the powder.

After the circumferential sprinkling operation is completed and the rotation of the rotary disk 711 is temporarily stopped, the disk 721 of the scraped disk portion 72 is rotated downward, and the disk 721 is in close contact with the arcuate concave portion (sink portion 712). To do so. In that state, the motor 722 is driven, the stepping motor 714 is rotated by a predetermined angle, and the rotary disk 711 is rotated by a predetermined angle. As a result, a predetermined amount (for example, one packet) of powder is sent to the powder packaging unit 74 via the hopper chute 73.

In one embodiment of the present invention, two sets of the powder discharge device 60 and the disk distribution unit 71 are arranged symmetrically to the left and right, but this is performed by one of the disk distribution units 71 to perform a circumferential sprinkling operation. At the same time, the other side operates the scraping disk portion 72 to enable the distribution operation for one package, so that the packages can be continuously packaged in a plurality of consecutive prescriptions without wasting time.

The powder packaging unit 74 is a well-known technique, in which a packing paper is arranged at the outlet of the hopper chute 73, and the powder is sealed and packaged in the packing paper.

As described above, in the powder packaging machine 50 using the powder vibration transport device 10 of the present invention as the powder discharging device 60, the height of powder discharging (dropping) from the powder discharging device 60 to the powder packaging device 70 is reduced. Therefore, troubles such as scattering of powder can be prevented, and various advantages of the powder vibration transport device 10 can be enjoyed.

In the above description, the object to be handled as the powder vibration transport device 10 has been described as an example of powder, but any other powdery or granular material may be used. ..

<Another Embodiment of the powder vibration transport device>
Further, in the description so far, in the powder vibration transport device 10, both the piezoelectric vibration unit 13 and the support 12 have the lower end at the front in the powder transport direction and the upper end at the rear in the powder transport direction. Moreover, it has been assumed that the stretching directions are parallel to each other.

However, the problem of the present invention can be solved without such a configuration. FIG. 7 is a side view of the powder vibration transport device according to another embodiment of the present invention, in which the inclination of the piezoelectric vibration portion 13 is gentler than the inclination of the support 12.

That is, in FIG. 4 used earlier, as shown in FIG. 4 (b), in this embodiment, the angle R1 formed by the support 12 and the angle R3 formed by the piezoelectric vibrating portion 13 with respect to the shaking table 11 are , Each is smaller than 90 degrees, and R1> R3. The amount of sinking of the shaking table 11 generated by the deformation of each of the support 12 and the amplification spring 132 of the piezoelectric vibration unit 13 is S1 at the position (front end side) of the support 12 and the piezoelectric vibration unit 13. Since S3 is formed at the position (rear end side) and S1 and S3 are substantially equal to each other, the difference in the amount of subduction of the shaking table 11 is smaller than that in the case of one embodiment of the present invention shown in FIG. 4 (a). , Allows for smoother vibration transport.

Further, in the present embodiment, since the inclination of the piezoelectric vibration unit 13 is gentle, the height in the vertical direction from the base 14 to the upper end of the piezoelectric vibration unit 13 becomes low, thereby increasing the height of the entire powder vibration transport device 10. There is also an advantage that the device becomes compact.

<Another Embodiment of the Powder Vibration Transport Device>
Further, in the above description, the support 12 has been described as a thin plate having elasticity, but the present invention is not limited to this, and another member may be used.

<Different aspects of powder vibration transport equipment>
Further, the present invention includes the powder vibration transport device 10 described above and the rotary disk 711 having a saucer portion 712 having a concave cross section on the outer peripheral portion for receiving the powder discharged from the powder vibration transport device 10. The powder vibration transport device with a rotating disk may be used, wherein the saucer portion 712 is arranged directly below the powder discharge port 151 of the powder vibration transport device 10.

That is, the invention was made up to the point where a rotating disk 711 having a saucer portion 712 was added to the powder vibration transport device 10, and up to this part was independently incorporated into the powder packaging machine and was limited to powder. It is also possible to use other powders, such as foods, for other purposes not limited to packaging.

FIG. 8 is a side view of the powder vibration transport device according to still another embodiment of the present invention, in which a rigid support 12A is used instead of the elastic thin plate support 12, and the shafts 12B above and below the rigid support 12A. It is a link mechanism that is rotatably supported by the shaft 12C and the shaft 12C.

Even with such a configuration, the same operation as described above can be realized, and there may be an effect that the manufacturing cost is reduced and the adjustment man-hours are reduced.

The inclination of the rigid support 12A and the piezoelectric vibrating portion 13 with respect to the shaking table 11 is gentler in the piezoelectric vibrating portion 13, but may be parallel.

<Another Embodiment of the powder packaging machine>
In the description of the powder packaging machine 50 so far, it has been described that the powder discharging device 60 does not have the weight measuring unit 16, but it may be provided. (Not shown)

In this way, in addition to the advantage of the powder packaging machine of the above-described embodiment, there is an advantage that the amount of powder released can be accurately measured.

Since the present invention can provide a powder vibration transport device having a simple structure, less trouble, and a low cost, it can be used in a wide range of industrial fields dealing with powders as well as powder packaging in the chemical dispensing department. There is sex.
