JP7566317B2 - Powdered medicine distribution device, powdered medicine packaging device, and powdered medicine storage container - Google Patents

Description

The present invention relates to a powder medicine distribution device that supplies and distributes powder medicine in small amounts to a distribution disk , a powder medicine packaging device that supplies and packages powder medicine one packet at a time , and a powder medicine storage container that releases a fixed amount of powder medicine .

In conventional powder medicine packaging devices, a pharmacist weighs the weight of a prescription of powder medicine and places the weighed powder medicine in a hopper. The bottom of the hopper has a vibration surface that is inclined slightly downward from the horizontal plane, and by vibrating the vibration surface, the powder medicine inside is released through a release port and rolled up into a groove provided on the outer periphery of a rotating disk, forming a ring-shaped pile of powder medicine. One packet at a time is then released from the ring-shaped pile of powder medicine and placed in wrapping paper. However, this requires the pharmacist to weigh the weight of the powder medicine each time, which places a heavy burden on the pharmacist. To solve this problem, there is a device that uses an actuator to release the powder medicine from a container that contains the powder medicine onto a distribution disk, and measures the weight of the released powder medicine by measuring the weight of the distribution disk (Patent Document 1).

In addition, a technology for supplying a fixed amount of powdered material, although not a powdered medicine, is known in which a screw shaft with a threaded groove on its outer periphery is inserted rotatably into the bottom of an inverted cone-shaped hopper, and the powdered material is discharged from the bottom of the hopper by rotating the screw shaft (Patent Document 2).

A typical powdered medicine dispenser hopper only requires a degree of agreement with the measurement target value, but the distribution disk weighing method requires a constant flow rate while the powder is being spread on the distribution disk. If this consistency fluctuates, unevenness in the mass of the accumulated powdered medicine will occur within a 360° circumference of the distribution disk, and the mass of powdered medicine contained in each packet will differ. If the measurement target value is large, the number of rotations of the distribution disk until the powdered medicine is completely dispensed will be large enough to diffuse this mass unevenness in the circumferential direction. However, in the case of prescriptions for newborns and children, the total amount of the prescription may be small, such as 0.5 g, and the number of rotations of the distribution disk until this 0.5 g is completely dispensed may be reduced, and there is a risk that the mass error in the 360° circumference of the distribution disk may not be sufficiently diffused.

Patent No. 6777832 JP 2000-211747 A

The technology described in Patent Document 1 does not take into consideration the even supply of extremely small amounts of powdered medicine to the distribution disk, and when a small amount of powdered medicine is distributed, the powdered medicine wound on the distribution disk becomes uneven in the circumferential direction.

In addition, in Patent Document 2, the vertical screw is connected from the bottom of the inverted cone-shaped container to a cylindrical section that roughly matches the outer shape of the screw. In this case, the top of the screw does not contact the container wall, but the bottom of the screw does contact the cylinder.

This causes problems such as the powder being compressed and easily remaining in the wedge-shaped portion between the top of the screw and the bottom of the inverted cone-shaped container, or conversely, the powder at the bottom being caught in the recess of the screw, causing the bulk density of the powder layer in the recess to become uneven. On the other hand, at the bottom of the screw, the powder in the recess comes into contact with the inner wall of the cylinder and experiences frictional resistance, causing the powder layer to become uneven. Both of these effects cause the mass of powder falling from the bottom end of the screw to become uneven.

An object of the present invention is to provide a powder medicine distribution device , a powder medicine packaging device, and a powder medicine storage container that improve the uniformity of powder medicine distributed onto a distribution disk.

The powdered medicine distribution device of the present invention includes a powdered medicine supplying device having a powdered medicine storage container that stores powdered medicine inside and releases the stored powdered medicine little by little, a distribution disk that receives the powdered medicine released from the powdered medicine supplying device and rotates to evenly distribute the powdered medicine near the outer periphery, and a rotation drive unit on which the distribution disk is placed and that drives the distribution disk to rotate. and a weighing unit that is provided below the rotary drive unit and measures the weight of the powdered medicine supplied from the powdered medicine supply device to the distribution disk by measuring the total weight of the distribution disk and the rotary drive unit excluding the powdered medicine supply device. The powdered medicine storage container has a medicine container body with a cylindrical interior that stores the powdered medicine inside, an inverted cone section that is provided at the bottom of the medicine container body and has an interior that narrows in diameter toward the bottom, and a cylindrical section formed below the inverted cone section. A screw that extends from the medicine container body to the cylindrical section of the powdered medicine discharger and is formed close to the inner wall of the cylindrical section on the outer periphery of the part that corresponds to the inverted cone section and rotates to push the powdered medicine in the inverted cone section along the recess of the screw. The screw has a powdered medicine supply shaft which transports the powdered medicine downward and releases it from the lower end of the cylindrical portion, and which is formed only in the lowest recess of the screw, protruding radially from the recess, and has a ridge formed at its tip which loosens the powdered medicine transported by the recess of the screw, and a stirring member which is provided at the tip of a support portion which protrudes radially from the powdered medicine supply shaft, close to the inner surface of the inverted cone portion, and which rotates together with the powdered medicine supply shaft to transport the powdered medicine near the inner wall surface of the inverted cone portion to the powdered medicine supply shaft, and the stirring member is formed as a triangular prism with one side facing the inner wall of the inverted cone portion and the side that does not contact the side is provided on the support portion side, and the angle formed by the side sides which sandwich the edge of the tip in the direction of rotation is an acute angle.

The powder medicine packaging device according to the embodiment will be described below with reference to the drawings.

Figure 1 is a perspective view of the disk distribution section, which is a part of the powdered medicine packaging device of this embodiment, and Figure 2 is a front view of the powdered medicine packaging device. In Figures 1 and 2, the disk distribution section is composed of a weighing device 10, a rotary drive unit 30 arranged above the weighing device 10, and a powdered medicine distribution disk 20 installed on the rotary drive unit 30. The weighing device 10 is fixed to the housing connection unit 16 of the packaging device. A powdered medicine supply device 60 fixed to a housing (not shown) is provided above the distribution disk 20. This powdered medicine supply device 60 has a powdered medicine storage container 62 detachably fixed to a support member 61 fixed to a housing (not shown), and a motor 63 that rotates and drives a rotating shaft (powdered medicine supply shaft) in the powdered medicine storage container 62.

50 is a scraping section that scrapes out powdered medicine packets one at a time from the distribution disk 20, and the powdered medicine scraped out by this scraping section 50 is sent to the packaging device described later by a drop hopper 51.

Next, the powdered medicine supply device 60 will be described in detail with reference to Figures 3 to 6. Figure 3(a) is a cross-sectional view of the powdered medicine storage container 62, showing the state in which the shutter 622 is closed, and Figure 3(b) shows the state in which the shutter 622 is open. The powdered medicine storage container 62 is composed of a medicine storage section main body 624 with a cylindrical interior that stores the powdered medicine and is provided at the top, an inverted cone section 626 that is provided at the bottom of the medicine storage section main body 624 and whose interior diameter decreases toward the bottom, and a cylindrical section 628 that is formed integrally with the inverted cone section 626 below the inverted cone section 626. The inverted cone section 626 and the cylindrical section 628 form the powdered medicine release section.

In addition, a rotary drive shaft 630 that is rotated by a motor 63 is provided inside the medicine container body 624. Although not shown in the figure, a magnetic non-contact power transmission mechanism that is rotated by the rotary shaft of the motor 63 is attached to the upper part of this rotary drive shaft 630.

The lower part of the rotary drive shaft 630 is connected to the rotary drive shaft 630 and is provided with a powdered medicine supply shaft 632 which rotates together with the rotary drive shaft 630. Figure 4(a) is a cross-sectional view taken from above along line A-A in Figure 3, with the upper part of the powdered medicine supply shaft 632 rotatably guided by a bearing 636 fixed to three guides 634 extending from the inverted cone section 626. Figure 5 is a perspective view taken from below of the powdered medicine storage container 62, showing the state in which the shutter 622 closing the powdered medicine discharge port 639 is open. As can be seen from Figures 3 and 5, the lower part of the powdered medicine supply shaft 632 is supported by a bearing 638 provided at the lower part of the cylindrical section 628.

640 is an opening and closing mechanism for the shutter 622, and the shutter 622 is closed when the shutter drive unit 642 is biased upward by a spring 644. In addition, the shutter drive lever 64 is driven downward by a motor (not shown), which presses the shutter drive unit 642 downward, causing the shutter 622 to rotate around the pivot 623, and opening the shutter 622.

A screw 633 is formed on the outer periphery of the powdered medicine supply shaft 632, extending from the inverted cone section 626 to the part corresponding to the cylindrical section 628, and is close to the inner wall of the cylindrical section 628. The gap between the outer periphery of the screw 633 and the inner wall of the cylindrical section 628 may be partially in contact as long as the gap is close enough that the powdered medicine contained therein does not fall. With this configuration, as the powdered medicine supply shaft 632 rotates, the powdered medicine in the inverted cone section 626 is transported downward along the recess of the screw 633 and released from the powdered medicine release port 639 at the bottom of the cylindrical section 628.

Figure 6 shows a schematic diagram of the relationship between the screw 633 of the powdered medicine supply shaft 632 and the cylindrical portion 628, with Figure 6(a) showing a cross-sectional view and Figure 6(b) showing the screw 633 of the powdered medicine supply shaft 632 as viewed from below. In Figure 6(a), the powdered medicine supply shaft 632 rotates in a clockwise direction 120 as viewed from above. Also, Figure 6(b) shows the screw 633 as viewed from below, so the rotation direction is counterclockwise.

The screw 633 of the powder supply shaft 632 has a lead formed with a pitch L, and the powder P is stored in the recess of the screw 633, and the powder P is transported downward as the powder supply shaft 632 rotates.

When powdered medicine P is transported only by the rotation of screw 633, the powdered medicine P in the recess of screw 633 at the bottom of screw 633 tends to be compressed by friction with the inner wall of cylindrical portion 628 and form a lump (a so-called "ball"). If screw 633 continues to rotate and powdered medicine P is released from powdered medicine release port 639 at the bottom of screw 633, the powdered medicine P may fall in a lump state. If powdered medicine P is released to distribution disk 20 in such a lump state, the powdered medicine P will be distributed unevenly around the circumference of distribution disk 20.

To prevent this, in this embodiment, a ridge 652 is formed only in the recess 650 at the bottom of the screw 633, protruding radially from the recess at a position 1/2L of the lead of the recess 650. The height of this ridge 652 is formed so that it gradually increases from the tip in the rotation direction, as can be seen from FIG. 6(b). Furthermore, the width of this ridge 652 (the axial thickness of the powdered medicine supply shaft 632) is formed so that it gradually increases from the tip in the rotation direction, as can be seen from FIG. 6(a). Therefore, the rotation of the powdered medicine supply shaft 632 can produce the effect of breaking up the lumps of powdered medicine P contained in the recess of the screw 633 by the tip of the ridge 652. Therefore, the powdered medicine P is not released as a lump, and the powdered medicine can be evenly distributed on the distribution disk 20.

As shown in FIG. 3, the powdered medicine supply shaft 632 is provided with two support parts 635 formed to protrude radially from the powdered medicine supply shaft 632. The tips of these support parts 635 are provided with a stirring member 637 provided along the vicinity of the inner wall surface of the inverted cone section 626. This stirring member 637 rotates together with the rotation of the powdered medicine supply shaft 632, and has the function of transferring the powdered medicine P near the inner wall of the inverted cone section 626 to the powdered medicine supply shaft 632 side.

That is, the shape of the stirring member 637 is a triangular prism as shown in FIG. 4, with one side surface 637a of the triangular prism facing the inner wall of the inverted cone section 626, and the side that does not contact the side surface being connected to the support section 635. Furthermore, the angle θ formed by the two side surfaces that sandwich the side surface 637b at the tip of the stirring member 637 in the rotation direction is an acute angle.

When the powdered medicine P is transported downward by the screw 633 of the powdered medicine supply shaft 632, only the powdered medicine P near the powdered medicine supply shaft 632 is released, and the powdered medicine P is reduced in the center of the inverted cone section 626 like a so-called "antlion trap." However, by configuring the stirring member 637 in such a triangular prism shape, the powdered medicine P near the inner wall of the inverted cone section 626 can be collected near the powdered medicine supply shaft 632. In this embodiment, only one stirring member 637 is provided around the powdered medicine supply shaft 626, but it is of course possible to provide two or more. Also, 631 is a stirring member provided inside the medicine container main body 624.

Next, the powder medicine packaging device will be described with reference to FIG. 2 and FIG. 7 to FIG.
Fig. 7 is a perspective view of the state where the distribution disk 20 is removed from the disk distribution unit, and Fig. 8 is a front view of the state where the distribution disk 20 is removed from the disk distribution unit. Fig. 9 is a view showing the state where the rotation drive unit 30 is disassembled and the motor 32 and pulley 38 are moved upward from the base 31 of the rotation drive unit 30.

As shown in Figures 7 to 9, the base 31 of the rotary drive unit 30 is fixed to the measured object placement unit 12 of the weighing device 10. As shown in the exploded view of Figure 9, a bearing 35 is fixed to the base 31, and a pulley 38 is rotatably provided around this bearing 35. A distribution disk base 36 is fixed to the top of this pulley 38, and the distribution disk 20 is detachably fixed to the top of this distribution disk base 36.

A timing gear is formed on the outer periphery of the pulley 38, and a timing belt 34 is stretched between the pulley 38 and a timing gear 33 attached to the shaft of a motor 32 fixed to the base 31.

By configuring in this way, the weighing device 10 includes the base 31 of the rotary drive unit 30 fixed to the measured object placement unit 12 of the weighing device 10, and is capable of measuring the total weight of the motor 32, pulley 38, bearing 35, distribution disk base 36, distribution disk 20, etc., which are provided on the base 31. In other words, when no powdered medicine is supplied to the distribution disk 20, the weight of the container of the rotary drive unit 30, etc. is measured.

Returning to FIG. 2, powdered medicine is dropped little by little from the powdered medicine supplying device 60 provided on the top of the distribution disk 20 into the grooves of the distribution disk 20. This powdered medicine supplying device 60 is fixed to the housing of the packaging device and is not subject to weight measurement by the weighing device 10. Therefore, the weighing device 10 measures the total weight of the rotation drive unit 30 fixed to the measured object placement unit 12, the distribution disk 20, etc., plus the weight of the powdered medicine supplied from the powdered medicine storage container 62 to the distribution disk 20. Therefore, the weight of the powdered medicine actually supplied from the powdered medicine storage container 62 to the distribution disk 20 can be calculated by subtracting the weight of the tare described above from the weight measured by the weighing device 10.

When supplying powdered medicine from the powdered medicine storage container 62 to the distribution disk 20, the distribution disk 20 is rotated by the motor 32 while the motor 63 of the powdered medicine supply device 60 is rotated, causing the powdered medicine to fall from the powdered medicine storage container 62 onto the distribution disk 20. This forms a ring-shaped pile of powdered medicine on the distribution disk 20.

50 is a scraping section for dropping the annular powdered medicine formed on the distribution disk 20 into a drop hopper 51 one packet at a time. This scraping section 50 has a lever 53 that can be rotated up and down around an axis 54 by a motor 52. A disk 55 is attached to the tip of this lever 53, and it can be rotated in the direction of arrow 56a by a motor 56. When the powdered medicine is to be wound onto the rotating distribution disk 20, the lever 53 rotates counterclockwise and the disk 55 moves away from the distribution disk 20, and when the powdered medicine is to be distributed from the distribution disk 20, the lever 53 rotates clockwise and the disk 55 comes into contact with the distribution disk 20.

Then, as the disk 55 rotates, the powdered medicine wound on the distribution disk 20 is dropped one packet at a time into the drop hopper 51, where it is stored between the folded packaging paper 57. The scraping unit 50 is a well-known technology, and is described, for example, in JP 2019-202801 A.

Here, a weighing device 10 is provided below the distribution disk 20, and the packaging paper 57 containing the powdered medicine cannot be transported horizontally as described in JP 2019-202801 A. In other words, in order to drop the powdered medicine released from the distribution disk 20 into the drop hopper 51 and store it in the packaging paper that is transported horizontally, it is necessary to make the drop hopper 51 long vertically. This means that the powdered medicine will pass through a long drop hopper, and more powdered medicine will adhere to the drop hopper, which may result in an inaccurate weight of the packaged powdered medicine. In addition, the drop hopper 51 will be large, which may result in the packaging device also being large.

For this reason, as shown in FIG. 2, a diagonal transport packaging device is used as the packaging device 70. That is, the packaging device 70 has a horizontal transport and a roll (not shown) on which the folded packaging paper 57 is wound, and the bottom surface of the packaging device 70 is attached diagonally to the packaging device. The packaging paper 57 is pulled forward from the roll and transported diagonally downward to the right on the front side.

2, the powdered medicine distributed from the distribution disk 20 is dropped into the drop hopper 51 just below the distribution disk 20 and stored between the folded packet papers 57. The packet papers 57 containing the powdered medicine are sealed one by one in the packaging device 70 and transported diagonally to the lower right in the figure, passing under the weighing device 10 and being accumulated in the packaged medicine accumulation section 75. In this way, by making the transport path for the packet papers 57 of the packaging device 70 diagonal transport, the device can be configured without increasing the size even if the weighing device 10 is provided below the distribution disk. The packet papers 57 containing the powdered medicine may be wound up by a reel provided in the packaged medicine accumulation section 75, or may be transported and discharged outside the machine.

Figure 10 is a block diagram of a powdered medicine packaging device. In Figure 10, 300 is a powdered medicine packaging device, and its overall control unit 310 is connected to a prescription system 400 of a pharmacy. The overall control unit 310 is connected to a packaging device 70 and a disk distribution control unit 340 of a disk distribution unit 330. The disk distribution control unit 340 of the disk distribution unit 330 is connected to a first motor 32 for rotating the distribution disk 20, a second motor 52 for driving the scraping disk lever, a third motor 56 for rotating the disk, a drive motor 63 for the powdered medicine supply device 60, and a weighing unit 10.

Next, the weighing operation of the disk distribution unit configured in this manner will be explained with reference to Figure 11.

When the powder medicine packaging operation is started, the overall control unit 310 acquires the type of powder medicine to be prescribed and the weight information of one prescription of powder medicine from the prescription system 400 (ST1). The overall control unit 110 outputs the acquired powder medicine weight information to the disk distribution control unit 340 of the disk distribution unit 330. The disk distribution control unit 340 then drives the motor 32 of the rotation drive unit 30 to rotate the distribution disk 20 (ST2), completing preparations for supplying powder medicine to the distribution disk 20. Then, before the powder medicine is supplied, the weight of the container of the distribution disk 20 and the rotation drive unit 30 is measured (ST3). The weight of this container may be subtracted from the weight measured after the powder medicine is supplied to calculate the weight of the powder medicine only, or the weight of the powder medicine only may be obtained by using the measured weight of the container as a zero reference.

Then, the disk distribution control unit 340 operates a shutter opening/closing (opening/closing arm driving) motor (not shown) to drive the shutter drive lever 64 and open the shutter 622 of the powdered medicine storage container 62 (ST4), and rotates and drives the drive motor 63 of the powdered medicine supply device 60 (ST5), causing the powdered medicine to drop little by little from the powdered medicine storage container 62 onto the distribution disk 20. While the powdered medicine is being dropped in this way, the weighing device 10 measures the weight of the powdered medicine dropped onto the distribution disk 20 (ST6).

Then, while supplying the powdered medicine, it is determined whether the measured weight of the powdered medicine has reached the weight of one prescribed amount (ST7), and this continues until the weight of the powdered medicine supplied reaches the weight of one prescribed amount. When the weight of one prescribed amount is reached, the drive motor 63 of the powdered medicine supply device 60 is stopped, and the shutter opening/closing motor (for driving the opening/closing arm) is operated to close the shutter 622 of the powdered medicine storage container 62, and further the motor 32 of the rotation drive unit 30 is stopped (ST8).

When a prescription of powdered medicine is supplied to the distribution disk 20, the second motor 52 is rotated, and the scraping disk 55 is moved so as to come into contact with the distribution disk 20. Then, the third motor 56 and the distribution disk 20 are rotated intermittently, and the scraping unit 50 performs a scraping operation in which the powdered medicine is dropped one packet at a time into the drop hopper 51 (ST9). The powdered medicine dropped into the drop hopper 51 is sealed one packet at a time by the packaging device 70 and accumulated in the packaged medicine accumulation unit 75.

According to the embodiment configured as described above, it is possible to release small amounts of powdered medicine from the powdered medicine storage container 62 onto the distribution disk 20, and even small amounts of powdered medicine can be evenly distributed around the circumference of the distribution disk 20.

Although several embodiments and variations of the present invention have been described, these embodiments and variations are presented as examples and are not intended to limit the scope of the invention. These new embodiments and variations can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention.
