Description

[Technical field]

[0001] The present invention relates to a powder medicine packaging device, and more particularly to a powder medicine scraping section that scrapes out a fixed amount of powder medicine contained in a groove of a powder medicine containing member. [Background technology]

[0002] Conventionally, powder medicine packaging devices are equipped with a powder medicine scraping device that uniformly supplies powder medicine to a powder medicine storage member (also called an R-disk or distribution dish) having an annular groove with an arc-shaped cross-section, and distributes and scrapes out the powder medicine in the annular groove one packet at a time using a rotating plate with a scraping plate (see Patent Documents 1 and 2).

[0003] In the conventional powder medicine packaging device, as shown in Fig. 16, the rotating plate 102 is lowered to cut the powder medicine contained in the powder medicine storage member 101, and when the first package of powder medicine is scraped out by the scraping plate 103 of the rotating plate 102, the powder medicine stored in the powder medicine storage member 101 is scraped out to the opposite side of the scraping plate 103 when the powder medicine with a narrower division width S is scraped out than the scraping width W according to the number of packets. However, the powder medicine stored in the powder medicine storage member 101 is scraped out to the opposite side of the scraping plate 103 by reversing the rotation of the powder medicine storage member 101. However, the more the number of packets, the more the amount of scraping increases, so that the powder medicine scraped out to the opposite side of the scraping plate 103 flows into the N-1th package, the more the N-1th package, and the fewer the Nth package, and it is not possible to divide evenly. Therefore, in the conventional packaging device, depending on the dimension of the scraping width W of the scraping plate 103, the maximum number of divisions was 93 packets at most. When the number of packets exceeds the maximum division number, the necessary amount of powdered medicine is divided into two portions and stored in the powdered medicine storage member 101. For example, in the case of 100 packets, first 50 packets of powdered medicine are stored in the powdered medicine storage member 101 and divided into 50, and then the remaining 50 packets of powdered medicine are stored in the powdered medicine storage member 101 and divided into 50, which takes a long time to complete the packaging work.

[0004] Patent Document 3 describes a packaging device that has a narrow cutting member (screw plate) and a wide cutting member (screw plate) on one side of a rotating member, and scrapes out the first package with the narrow cutting member and scrapes out the second and subsequent packages with the wide cutting member. The packaging device of Patent Document 3 has a problem in that it takes a long time to complete packaging because, after the second and subsequent packages are scraped out with the wide cutting member, the narrow cutting member raises the rotating member that passes through the rotary table.

[0005] Patent Document 4 describes a packaging device that includes a first scraping member on a first surface of a rotating member, a second scraping member on a second surface of the rotating member that is wider than the first scraping member, and scrapes out the powder medicine using the wide second scraping member while rotating the turntable in a first direction for the division number of 1 to 63, and scrapes out the powder medicine using the narrow first scraping member while rotating the turntable in a second direction different from the first direction for the division number of 64 to 93. In the packaging device of Patent Document 4, a narrow scraping member is used from the first packet to the final packet for the division number of 64 to 93, so the feed amount of the turntable becomes smaller as the division number increases, and after the first packet is scraped out with the narrow scraping member, the wide scraping member scrapes out part of the powder medicine in the final packet before scraping out the second packet, so the maximum division number is 93 packets.

[0006] Patent Document 5 describes a powder / granule dividing device that is provided with a wide-width cutting member and a narrow-width cutting member on one side of the damming part for cutting out powder medicine stored in the annular groove of the table, and when dividing into multiple parts, the first part is cut out by the narrow-width cutting member, and the second and subsequent parts are cut out by the wide-width cutting member, and when dividing into small parts, the first to final parts are cut out by the wide-width cutting member. In the device of Patent Document 5, since the wide-width cutting member and the narrow-width cutting member are provided on the same side of the damming part, after cutting with the wide-width cutting member, the narrow-width cutting member passes through the annular groove, and the narrow-width cutting member scrapes out the part of the powder medicine in the annular groove that was not cut out after cutting with the wide-width cutting member, resulting in an excessive scraping out of the collapsed part and an increased scraping out amount. In addition, in the device of Patent Document 5, when cutting out a width wider than the width of the wide cutting member as one package, the annular groove of the table is rotated to gather the powder medicine beyond the wide cutting member at the damming section (rotating plate) and then scrape it out, but the larger the width of the gathering, the more the powder tends to collapse after being scraped out. If the number of collapses increases, the amount of the collapsed part scraped out when the narrow cutting member passes after the wide cutting member also increases. For this reason, the gathering width is limited and the limit of the gathering width is set small, which results in a problem that the number of scrapings increases and it takes a long time to pack the powder.

[0008] The present invention has been made in consideration of the above-mentioned conventional problems, and has an object to provide a powder medicine packaging device that can scoop out the required number of powder medicine packets by simply dispersing the required amount of powder medicine into a powder medicine storage member once, even if there are a large number of packets. [Means for solving the problem]

[0009] As a means for solving the above problems, the powder medicine packaging device of the present invention is A rotatable powdered medicine storage member having a groove with an arc-shaped cross section; A powder medicine packaging device comprising: a rotating plate that is rotatable in contact with the groove and is provided so as to be movable up and down relative to the groove, and that has a scraping plate that scrapes out the powder medicine contained in the powder medicine storage member; The scraping plate includes a first scraping plate provided on a first surface of the rotating plate and a second scraping plate provided on a second surface of the rotating plate and having a scraping width smaller than that of the first scraping plate; The second scraping plate scrapes out the first packet of powdered medicine at a predetermined dividing width, The powdered medicine container is configured so that after the powdered medicine container is moved from the second surface side to the first surface side of the rotating plate, the first scraping plate scrapes out the powdered medicine from the second packet onwards at a predetermined division width.

[0010] In the powdered medicine packaging device, the powdered medicine storage member is moved from the second surface side to the first surface side so that the powdered medicine of the division width corresponding to the number of packets is scraped out when the first packet is scraped out by the narrow second scraping plate, and the powdered medicine stored in the powdered medicine storage member is scraped to the opposite side of the second scraping plate, but the scraping amount is small because the scraping width of the second scraping plate is small. Therefore, even if the number of packets is large, the powdered medicine scraped to the opposite side of the second scraping plate fits within the division width of the second packet and is scraped out when the second packet is scraped out by the first scraping plate.

[0011] It is preferable that the powdered medicine storage member is configured to move from the first surface side to the second surface side after the second scraping plate has finished scraping the first packet of powdered medicine and before the first scraping plate begins scraping the second packet of powdered medicine. It is also preferable that after the first scraping plate scrapes out the powdered medicine, the powdered medicine storage member is moved from the first surface side to the second surface side, and then the second scraping plate enters the powdered medicine storage member.

[0012] The first scraping plate and the second scraping plate are preferably provided at equally spaced positions around the central axis of the rotating plate.

[0013] It is preferable that two first scraping plates and one second scraping plate are provided.

[0014] It is preferable that the powdered medicine storage member is configured to be moved from the first surface side to the second surface side after the first scraping plate has finished scraping the powdered medicine and before the subsequent first scraping plate begins scraping the powdered medicine. In this case, it is preferable that the first scraping plate scoops out the powdered medicine, and after the second scraping plate has scooped out the powdered medicine, the second scraping plate enters the powdered medicine storage member before the first scraping plate enters the powdered medicine storage member.

[0015] The program according to the present invention comprises: A control device for controlling the powdered medicine storage member and the rotating plate of the powdered medicine packaging device, A step of scraping out the first powdered medicine packet at a predetermined division width by the second scraping plate; After moving the powdered medicine storage member from the second surface side to the first surface side of the rotating plate, the first scraping plate scrapes out the second package of powdered medicine at a predetermined division width; This is a program for executing a step of moving the powdered medicine storage member from the second surface side to the first surface side of the rotating plate, and then scraping out the powdered medicine from the third packet onwards at a predetermined division width using the first scraping plate.

[0016] The medium according to the present invention comprises: A computer-readable recording medium on which the program is recorded. Effect of the Invention

[0017] According to the present invention, the powdered medicine storage member is moved from the second surface side to the first surface side to scrape the powdered medicine stored in the powdered medicine storage member to the side opposite the second scraping plate so that when the first packet is scraped out by the narrow second scraping plate, a powdered medicine with a division width corresponding to the number of packets is scraped out.However, since the scraping width of the second scraping plate is small, the amount of powder scraped is small, so even if the number of packets is large, the powdered medicine scraped to the side opposite the second scraping plate falls within the division width of the second packet and is scraped out when the second packet is scraped out by the first scraping plate.As a result, the required number of packets of powdered medicine can be scraped out by simply sprinkling the required amount of powdered medicine into the powdered medicine storage member once.

[0019] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0020] 1 shows a powder medicine packaging device 1 according to an embodiment of the present invention. In this powder medicine packaging device 1, powder medicine inputted by a powder medicine input section 2 is scraped out one packet at a time by a powder medicine scraping section 3, and then packaged by a packaging section 4. In addition, the powder medicine packaging device 1 is provided with a tablet manual distribution section 5 that manually distributes tablets one packet at a time and supplies them to the packaging section 4.

[0021] As shown in Figure 2, the powder medicine input section 2 is equipped with an input hopper 6 and a powder medicine feeder 7, and is configured to supply the powder medicine input from the input hopper 6 to the powder medicine feeder 7 by vibration of the powder medicine feeder 7 to the powder medicine storage member 10 of the powder medicine scraping section 3.

[0022] The feeding speed of the powdered medicine feeder 7 can be increased or decreased by the operation panel 8 provided on the upper part of the powdered medicine packaging device 1. As shown in FIG. 3(a), the operation panel 8 is provided with 16 bar-shaped touch panels 9 for adjusting the feeder speed of the two powdered medicine input units 2, A and B, in 16 steps. When the power is turned on, the default value is set to 8 steps, and the touch panels 9 from the left 1st step to the 8th step are lit in yellow (shown by hatching in the figure). To increase the feeder speed, swipe your fingertip from the 8th step to the right, and to decrease the feeder speed, swipe your fingertip from the 8th step to the left. For example, as shown in FIG. 3(b), to increase the feeder speed to the 14th step, swipe your fingertip to the right from the 8th step to the 14th step. As a result, the touch panels 9 from the 8th step to the 14th step that were swiped are lit, and the set feeder speed can be recognized.

[0023] If the touch panel 9 is lit up in the range from the start of the swipe to the end when the touch panel 9 is swiped, the start point of the swipe is not known, and it is not possible to know how much the feeder speed has changed. In order to make it possible to recognize the amount of change in the feeder speed from the start of the swipe to the end, the touch panel 9 next to the swipe start point where the finger first touched until the finger is removed from the swipe end point is blinked as shown in FIG. 4(a), or the touch panel 9 is lit up in a different color from the swipe start point as shown in FIG. 4(b). This makes it possible to visually recognize the amount of change in the feeder speed.

[0024] As shown in FIG. 2, the powdered medicine scraping section 3 includes a powdered medicine storage member 10 and a powdered medicine scraping device 11.

[0025] The powdered medicine storage member 10 is made of a perforated disk with an annular groove 10a having an arc-shaped cross section formed on the outer periphery of the upper surface, and is rotated by the drive of a motor 12. The powdered medicine input from the powdered medicine input section 2 is evenly accommodated in the annular groove 10a.

[0026] As shown in FIG. 5, the powdered medicine scraping device 11 includes a base 13, an arm 14, and a rotating member 15.

[0027] The base 13 is disposed inside the powdered medicine storage member 10, and has a rotation motor 16 and a lifting motor 17. The rotation motor 16 transmits power from its motor gear (not shown) to a pulley 19 of a drive shaft 18 via an intermediate gear 16a and a drive gear 16b. The lifting motor 17 rotates a lifting gear 17b via a motor gear 17a, and raises and lowers a lifting platform 20 via a pin 17c provided on the lifting gear 17b.

[0028] One end of the arm 14 is rotatably attached to the drive shaft 18 of the base 13, and the other end is attached to a rotary shaft 23, which will be described later. A belt 22 is stretched between a pulley 19 of the drive shaft 18 and a pulley 21 of the rotary shaft 23, so that the rotational force of the drive shaft 18 is transmitted to the rotary shaft 23. The arm 14 is supported by a lifting platform 20, and is adapted to rotate at a predetermined angle around the drive shaft 18 to a scraping position and a retracted position as the lifting platform 20 rises and falls.

[0029] As shown in FIG. 6, the rotating member 15 is made up of a rotating shaft 23, a mounting base plate 24, and a rotating plate 25.

[0030] As described above, the rotating shaft 23 is rotatably attached to the tip of the arm 14.

[0031] The mounting base plate 24 is made of a stainless steel disk, and is attached to one end of the rotating shaft 23 so as to be able to rotate integrally with it. A triangular pyramid-shaped protrusion 26 is attached to the surface of the mounting base plate 24 facing the rotating plate. Conical mounting pins 27 are attached to symmetrical positions on both sides of the protrusion 26. The mounting pins 27 are provided so as to be able to slide in the radial direction, and are biased radially outward by a spring (not shown).

[0032] The rotating plate 25 is made of a stainless steel disk having the same radius of curvature as the circular arc of the annular groove 10a of the powdered medicine storage member 10, and an elastic edge 28 of silicon or the like is integrated by thermal fusion around the entire outer periphery. A triangular mounting hole 25a is formed in the center of the rotating plate 25, with which the protruding portion 26 of the mounting base plate 24 engages, and on both sides of the mounting hole 25a, positioning holes 25b consisting of elongated holes with which the mounting pins 27 of the mounting base plate 24 engage are formed. Two wide scraping plates (first scraping plates) 29a, 29b are integrally provided on the first surface (front surface) of the rotating plate 25 on the opposite side to the rotating shaft 23, and one narrow scraping plate (second scraping plate) 29c is provided on the second surface (back surface) on the same side as the rotating shaft 23.

[0033] The two wide scraping plates 29a, 29b and the narrow scraping plate 29c have the same shape except for the scraping width, so the wide scraping plate 29a will be described. The scraping plate 29a is formed by bending a plate-shaped body such as stainless steel to form a scraping section 30 and a partition section 31. An elastic piece 32 such as silicon is integrated with the tip of the scraping section 30. A part of the outer edge of the partition section 31 is formed in an arc shape along the annular groove 10a of the powdered medicine storage member 10. As shown in FIG. 7(a), the scraping width Wb of the narrow scraping plate 29c is formed smaller than the scraping width Wa of the wide scraping plates 29a, 29b. Also, as shown in FIG. 7(b), the two wide scraping plates 29a, 29b and the narrow scraping plate 29c are provided at equal intervals (120° intervals) around the central axis of the rotating plate 25.

[0034] Returning to Figure 2, the packaging section 4 is configured to receive powdered medicine scraped out from the powdered medicine scraping section 3 via a packaging hopper 42 into packaging paper 41 that is unwound from a paper roll 40 and folded in half, and then seal and discharge each packet using heater rollers 43a, 43b.

[0035] Fig. 8A shows an automatic cleaning system for the powder medicine packaging device 1. As shown in Fig. 11, the cleaning nozzle 50 and the suction hose 51 are provided on the right side of the front of the powder medicine packaging device 1, so that each part can be manually cleaned. The suction hose 51 is connected to a vacuum cleaner 53 provided inside the powder medicine packaging device 1 via a switching valve 52. The switching valve 52 includes a valve body 54, four suction nozzles (first to fourth) 55a, 55b, 55c, 55d, and one discharge nozzle 56.

[0036] The valve body 54 is cylindrical with one end closed and the other end open, and has a communication hole 54a formed in the peripheral wall. The valve body 54 is provided in the center of a casing 57 so as to be rotatable in both forward and reverse directions by a motor 58.

[0037] The ends of the first to fourth suction nozzles 55a, 55b, 55c, and 55d in the casing 57 are gathered around the valve body 54, and are in sliding contact with the valve body 54 in a sealed state, and are connected to the communication hole 54a of the valve body 54 at a predetermined stop position in the rotation direction of the valve body 54. The ends of the four suction nozzles 55a, 55b, 55c, and 55d outside the casing 57 are connected to the respective suction parts of the powdered medicine packaging device 1. That is, the first suction nozzle 55a is connected to the cleaning nozzle 50, the second suction nozzle 55b is connected to the suction part 59 on the upper side of the powdered medicine storage member (R disk) 10, the third suction nozzle 55c is connected to the suction part 60 of the powdered medicine scraping device 11 and the suction part 61 on the lower side of the powdered medicine storage member (R disk) 10, and the fourth suction nozzle 55d is connected to the suction part 62 of the packaging hopper 42.

[0038] The end of discharge nozzle 56 inside casing 57 is in sliding contact with and communicates with the open end of valve body 54 in a sealed state. The end of discharge nozzle 56 outside casing 57 is connected to vacuum cleaner 53.

[0039] Sensors 63a, 63b, 63c, 63d for detecting when communication hole 54a of valve body 54 reaches first to fourth suction nozzles 55a, 55b, 55c, 55d are provided on casing 57 of switching valve 52. Switching valve 54 is driven by motor 58 so that it can be stopped at a position where communication hole 54a faces any one of first to fourth suction nozzles 55a, 55b, 55c, 55d.

[0040] 8B, the vacuum cleaner 53 includes a filter 53a, a fan 53b, and a motor 53c for driving the fan 53b, and is provided with a detachable paper bag 64. The paper bag 64 is provided with a means for preventing the internal chemicals, dirt, dust, mites, etc. from scattering when the paper bag 64 is replaced.

[0041] That is, as shown in Fig. 8B, the paper pack 64 is composed of a rectangular mouth paper 65 having a suction port 65a in the center that communicates with the discharge nozzle 56, and a bag 66 attached to the mouth paper 65 and having an opening 66a that communicates with the suction port 65a of the mouth paper 65. The mouth paper 65 is attached by engaging with a predetermined position of the vacuum cleaner, and can be removed after use and replaced with a new paper pack 64. The mouth paper 65 has a double structure, with three sides closed and both ends of the remaining side closed and a notch 65b provided in the center. A rectangular intermediate paper 67 smaller than the mouth paper 65 is slidably inserted into the mouth paper 65. The intermediate paper 67 is provided with a tab 67a that can be pulled out from the notch 65b of the mouth paper 65, and a hole 67b that is approximately the same size as the suction port 65a of the mouth paper 65. When the intermediate paper 67 is inserted into the spout paper 65, the hole 67b of the intermediate paper 67 is located at the same position as the suction port 65a of the spout paper 65, and the suction port 65a of the spout paper 65 opens to take in the sucked medicine, garbage, dust, mites, etc. into the bag 66. When replacing the paper pack 64, the tab 67b of the intermediate paper 67 is pulled in the direction of the arrow, and the intermediate paper 67 closes the suction port 65a of the spout paper 65. Therefore, when the paper pack 64 is removed, the medicine, garbage, dust, mites, etc. in the bag 66 do not scatter.

[0042] The vacuum cleaner 53 is also provided with a means for detecting whether the paper pack 64 is full. Conventionally, a method for detecting a decrease in flow rate is used as a means for detecting whether the paper pack 64 is full, using a flow rate sensor provided in the discharge nozzle 56 to detect a decrease in flow rate. However, the criteria for judging whether the paper pack 64 is full from the detected flow rate are unclear, and accurate detection of fullness is not possible. In this embodiment, an acrylic plate 53d with a strain gauge attached is provided below the paper pack 64, and when the capacity or weight of the paper pack 64 increases, the acrylic plate 53d is bent by the pressure or weight, distorting the strain gauge, and the capacity or weight limit of the paper pack 64 can be measured via a bridge circuit (not shown). The output voltage of the bridge circuit can be adjusted and calibrated with a variable resistor so that it changes depending on the amount of distortion when no load is applied and when the paper pack is full (a weight equivalent to the allowable weight is placed). The variable resistor is changed to a digital potentiometer, and the voltage when no load is applied and when the paper pack is full is measured and used as a threshold value, and the adjustment and configuration work can be facilitated by controlling the variable resistor with software.

[0043] The automatic cleaning system automatically cleans four areas: the top of the powdered medicine storage member (R disc) 10, the bottom of the powdered medicine storage member (R disc) 10, the powdered medicine scraping device 11, and the packaging hopper 42. The top of the powdered medicine storage member (R disc) 10 is cleaned by rotating the powdered medicine storage member (R disc) 10 and sucking up the powdered medicine adhering to the inside of the annular groove 10a with a cleaner (not shown) arranged in the annular groove 10a. The bottom of the powdered medicine storage member (R disc) 10 is cleaned by rotating the powdered medicine storage member (R disc) 10 and sucking up the powdered medicine adhering to the back side of the powdered medicine storage member (R disc) 10 with a cleaner (not shown) arranged on the back side of the powdered medicine storage member (R disc) 10. The powdered medicine scraping device 11 is cleaned by rotating the rotating plate 25 and bringing a brush (not shown) into contact with the rotating plate 25 to suck up the powdered medicine adhering to the rotating plate 25 and the scraping plates 29a, 29b, and 29c. The packaging hopper 42 is cleaned by closing the opening of the packaging hopper 42 and sucking up the powdered medicine adhering to the inside.

[0044] Each time packaging of one prescription is completed, automatic cleaning is performed for each part. Conventionally, cleaning of four places was performed in sequence while switching the switching valve 52, so a total of eight steps including switching the switching valve 52 were required. In this embodiment, in order to shorten the cleaning time and improve efficiency, cleaning is performed simultaneously under the powdered medicine storage member (R disk) 10 and the powdered medicine scraping device 11. That is, as shown in FIG. 9, in step 1, the switching valve 52 is switched from the fourth suction nozzle 55d to the third suction nozzle 55c, and in step 2, the powdered medicine storage member (R disk) 10 and the powdered medicine scraping device 11 are rotated simultaneously to simultaneously clean under the powdered medicine storage member (R disk) 10 and the powdered medicine scraping device 11. In step 3, the switching valve 52 is switched from the third suction nozzle 55c to the fourth suction nozzle 55d, and in step 4, cleaning of the packaging hopper 42 is performed. In step 5, the switching valve 52 is switched from the fourth suction nozzle 55d to the second suction nozzle 55b, and in step 6, the powdered medicine storage member (R disk) 10 is rotated to clean the top of the powdered medicine storage member (R disk) 10. This reduces the conventional eight-step process to six steps, shortening the cleaning time and improving efficiency.

[0045] Next, the operation of the powder medicine scraping section 3 in the powder medicine packaging device having the above-mentioned configuration will be described.

[0046] In the following description, the surface of the rotating plate 25 on the side where the wide scraping plates 29a and 29b are located is referred to as the first surface or front surface, and the surface of the rotating plate 25 on the side where the narrow scraping plate 29c and the rotating shaft 23 are located is referred to as the second surface or back surface. In addition, the direction in which the powdered medicine storage member 10 is rotated from the first surface side of the rotating plate 25 to the second surface side is referred to as the forward direction, and the direction in which the powdered medicine storage member 10 is rotated from the second surface side of the rotating plate 25 to the first surface side is referred to as the reverse direction.

[0047] The powder medicine scraping operation by the powder medicine scraping unit 3 is controlled by a control device 70 shown in Fig. 10 provided in the powder medicine packaging device 1. A central processing unit 71 of the control device 70 controls the motor 12 of the powder medicine storage member 10, the rotation motor 16 and the lifting motor 17 of the powder medicine scraping unit 3 in accordance with a program stored in a ROM memory 72 and in cooperation with a RAM memory 73 to store the powder medicine specified in the prescription in the powder medicine storage member 10, divide it into the number of packets N specified in the prescription, and scrape it into the packaging hopper 42.

[0048] As shown in Fig. 11, in step 11, the motor 12 is driven to rotate the powdered medicine storage member 10, and the powdered medicine according to the prescription is uniformly dispersed from the powdered medicine input portion 2 into the annular groove 10a of the powdered medicine storage member 10. The operation of the powdered medicine input portion 2 and the adjustment of the feeder speed have already been described.

[0049] In step 12, it is determined whether the number of divided packets is 93 packets or less or 94 packets or more. In the conventional powdered medicine scraping device, the maximum number of divided packets is 93 packets, whereas in this embodiment, 94 packets or more can be divided. However, the operation is different when the number of packets is 93 packets or less and when the number of packets is 94 packets or more. This is because in this embodiment, the scraping width Wa of the wide scraping plates 29a, 29b is 1 / 93 of the perimeter at the center of the annular groove 10a of the powdered medicine storage member 10. In the following explanation, the case is divided into 93 packets or less where the division width is equal to or greater than the scraping width Wa of the wide scraping plates 29a, 29b, and 94 packets or more where the division width is equal to or less than the scraping width Wa of the wide scraping plates 29a, 29b.

[0050] <For 93 packets or less> If the number of packets is 93 or less, the rotating plate 25 is rotated in step 13, and stops at the first origin position where the narrow scraping plate 29c and the wide scraping plate 29a are on the inside and outside of the powdered medicine storage member 10, as shown in Fig. 12(a). Specifically, this is before the partition portion 31 of the wide scraping plate 29a enters the powdered medicine storage member 10 and after the scraping portion 30 of the narrow scraping plate 29c leaves the powdered medicine storage member 10. In step 14, when the rotating plate 25 is lowered into the annular groove 10a of the powdered medicine storage member 10, a part of the periphery of the rotating plate 25 cuts into the powdered medicine evenly stored in the powdered medicine storage member (R disk) 10.

[0051] In step 15, the powdered medicine storage member (R disk) 10 is rotated in the forward direction, and as shown in Figures 12(a) and 13(b), the powdered medicine on the first surface side of the rotating plate 25 is scraped up, and an area without powdered medicine is provided on the second surface side of the rotating plate 25, thereby adjusting the division width S of the powdered medicine scraped out by the wide scraping plate 29a. Here, if the perimeter of the deepest part of the annular groove 10a of the powdered medicine storage member 10 is L and the number of packets is N, the division width S of the powdered medicine is S = L / N, so the powdered medicine storage member 10 is rotated forward by the movement amount a obtained by subtracting the scraping width Wa of the wide scraping plate 29a from the division width S.

[0052] In step 16, the rotating plate 25 is rotated clockwise in Fig. 12(a) to cause the wide scraping plate 29a to scrape out the first packet of powdered medicine from the powdered medicine storage member 10. As shown in Fig. 12(b), after the scraping portion of the wide scraping plate 29a leaves the powdered medicine storage member 10, before the partition portion of the wide scraping plate 29b enters the powdered medicine storage member 10, in step 17, the powdered medicine storage member (R disk) 10 is rotated forward, and the powdered medicine storage member 10 is sent by a pitch equivalent to the division width S, as shown in Fig. 13(b).

[0053] In step 18, the rotating plate 25 is rotated clockwise in Fig. 12(b) to cause the wide scraping plate 29b to scrape out the second packet of powdered medicine from the powdered medicine storage member 10. After the scraping portion of the wide scraping plate 29b leaves the powdered medicine storage member 10 as shown in Fig. 12(c), before the partition portion of the narrow scraping plate 29c enters the powdered medicine storage member 10, in step 19, the powdered medicine storage member (R disk) is rotated forward, and the powdered medicine storage member 10 is sent by a pitch equivalent to the division width S as shown in Fig. 13(c).

[0054] Returning from step 20 to step 16, when rotating plate 25 is rotated, narrow scooping plate 29c enters powdered medicine storage member 10 before wide scooping plate 29a enters powdered medicine storage member 10. However, since at this point in time there is no powdered medicine of two division widths S on the second surface of rotating plate 25 on which narrow scooping plate 29c is provided, a miss occurs and the powdered medicine passes through without being disturbed.

[0055] Thereafter, the operation of scraping out the powdered medicine by the wide scraping plate 29a and the wide scraping plate 29b is repeated until the final Nth packet of powdered medicine is scraped out.

[0056] When it is determined in step 20 that the final Nth packet has been dispensed, the rotating plate 25 is raised in step 21 to terminate the powdered medicine dispensing operation.

[0057] When the number of packets is 46 or less, the above method requires a large width for scraping up the powdered medicine, so that the powdered medicine for one dose is scraped out twice using wide scraping plates 29a and 29b.

[0058] <For 94 packets or more> When the number of packets is 94 or more, the scraping width Wb of the narrow scraping plate 29c is 1 / 135 (10 mm in this embodiment) of the circumference at the center of the annular groove 10a of the powdered medicine storage member 10, so the operation when scraping out the first packet with the narrow scraping plate 29c differs depending on whether the number of packets is 94 to 134, when the number of packets is 135, or when the number of packets is 136 or more.

[0059] When the number of packets is between 94 and 134 or less, the division width (e.g., 12 mm) is larger than the scraping width Wb of the narrow scraping plate 29c, so before the first packet is scraped out by the narrow scraping plate 29c, the powdered medicine storage member 10 is rotated from the second surface side to the first surface side (2 mm in this embodiment), and the rotating plate 25 scrapes up the powdered medicine on the second surface side.

[0060] When the number of packets is 135, the dividing width (10 mm) is the same as the scraping width Wb of the narrow scraping plate 29c, so that the scraping action of the rotating plate 25 for scraping up the powdered medicine is not necessary.

[0061] If the number of packets is 136 or more, the division width (e.g., 5 mm) is smaller than the scraping width Wb of the narrow scraping plate 29c, so before the first packet is scraped out by the narrow scraping plate 29c, the powdered medicine storage member 10 is rotated from the first surface side to the second surface side (5 mm in this embodiment), and the rotating plate 25 scrapes up the powdered medicine on the first surface side.

[0062] In either case, the operation after the first packet is scraped out is the same, so below we will specifically explain the case where the number of packets is 136 or more.

[0063] If the number of packets is 136 or more, the rotating plate 25 is rotated in step 22 and stopped at the second origin position where the narrow scraping plate 29c and the wide scraping plate 29b are on the inside and outside of the powdered medicine storage member 10, as shown in Fig. 14(a). Specifically, this is before the partition portion 31 of the narrow scraping plate 29c enters the powdered medicine storage member 10 and after the scraping portion 30 of the wide scraping plate 29b leaves the powdered medicine storage member 10. In step 23, when the rotating plate 25 is lowered into the annular groove 10a of the powdered medicine storage member 10, a part of the periphery of the rotating plate 25 cuts into the powdered medicine evenly stored in the powdered medicine storage member (R disk) 10.

[0064] In step 24, the powdered medicine storage member (R disk) 10 is rotated in the forward direction, and as shown in Figures 14(a) and 15(a), the powdered medicine on the first surface side of the rotating plate 25 is scraped up, and an area without powdered medicine is provided on the second surface side of the rotating plate 25, thereby adjusting the division width S of the powdered medicine scraped out by the narrow scraping plate 29c. Here, if the circumferential length of the deepest part of the annular groove 10a of the powdered medicine storage member 10 is L and the number of packets is N, the division width S of the powdered medicine is S = L / N, so the powdered medicine storage member 10 is rotated forward by the movement amount b obtained by subtracting the division width S from the scraping width Wb of the narrow scraping plate 29c.

[0065] In step 25, the rotating plate 25 is rotated clockwise in FIG. 14(a) to scrape out the first packet of powdered medicine from the powdered medicine storage member 10 by the narrow scraping plate 29c. As shown in FIG. 14(b), after the scraping portion of the narrow scraping plate 29c leaves the powdered medicine storage member 10, before the partition portion of the wide scraping plate 29a enters the powdered medicine storage member 10, in step 26, the powdered medicine storage member (R disk) 10 is reversed to provide an area on the first surface side of the rotating plate 25 where there is no powdered medicine, and the division width S of the powdered medicine scraped out by the wide scraping plate 29a is adjusted. Here, since (Wb-S) amount of powdered medicine has already been scraped on the first surface side of the rotating plate 25, the actual division width Sa is Sa=S-(Wb-S)=2S-Wb. In this case, the amount of movement c of the powdered medicine containing member 10 is obtained by subtracting Sa from Wa, that is, d=Wa-(2S-Wb)=Wa+Wb-2S.

[0066] In step 27, the rotating plate 25 is rotated clockwise in Fig. 14(b) to cause the wide scraping plate 29a to scrape out the second packet of powdered medicine from the powdered medicine storage member 10. As shown in Fig. 14(c), after the scraping portion of the wide scraping plate 29a leaves the powdered medicine storage member 10, and before the partition portion of the wide scraping plate 29b enters the powdered medicine storage member 10, in step 28, the powdered medicine storage member (R disk) 10 is rotated forward to send the powdered medicine storage member 10 by the division width S.

[0067] In step 29, the rotating plate 25 is rotated clockwise in Fig. 14(c) to cause the wide scraping plate 29b to scrape out the third packet of powdered medicine from the powdered medicine storage member 10. After the scraping portion of the wide scraping plate 29b leaves the powdered medicine storage member 10, and before the partition portion of the narrow scraping plate 29c enters the powdered medicine storage member 10, in step 30, the powdered medicine storage member (R disk) is rotated forward, and the powdered medicine storage member 10 is sent by a pitch equivalent to the division width S, as shown in Fig. 15(c).

[0068] Returning from step 31 to step 27, when rotating plate 25 is rotated, narrow scooping plate 29c enters powdered medicine storage member 10 before wide scooping plate 29a enters powdered medicine storage member 10. However, since at this point in time there is no powdered medicine of two division widths S on the second surface of rotating plate 25 on which narrow scooping plate 29c is provided, a miss occurs and the powdered medicine passes through without being disturbed.

[0069] Thereafter, the operation of scraping out the powdered medicine by the wide scraping plate 29a and the wide scraping plate 29b is repeated until the final Nth packet of powdered medicine is scraped out.

[0070] When it is determined in step 31 that the final Nth packet has been dispensed, the rotating plate 25 is raised in step 21 to end the powdered medicine dispensing operation.

[0071] In the tablet dispensing device of the above embodiment, as shown in Figure 15, when the narrow scraping plate 29c scrapes out the first packet, the powdered medicine stored in the powdered medicine storage member 10 is moved from the second surface side to the first surface side to scrape the powdered medicine stored in the powdered medicine storage member 10 to the opposite side of the narrow scraping plate 29c, so that a powdered medicine of a division width S corresponding to the number of packets is scraped out. However, since the scraping width Wb of the wide scraping plate 29c is smaller than the scraping width Wa of the wide scraping plates 29a, 29b, the amount of powder scraped is small, so that even if the number of packets is large, the powdered medicine scraped to the opposite side of the narrow scraping plate 29c fits within the division width S of the second packet and is scraped out when the second packet is scraped out by the wide scraping plate 29a. As a result, the required number of packets of powdered medicine can be scraped out by simply spreading the required amount of powdered medicine once into the powdered medicine storage member 10.

[0072] In this embodiment, when the scraping width is 93 packets or less, which is greater than or equal to the width of the wide scraping plate (first scraping plate), the powdered medicine is scraped out using only the wide scraping plate (first scraping plate), and when the scraping width is 94 packets or more, which is less than or equal to the width of the wide scraping plate (first scraping plate), the first packet is scraped out using the narrow scraping plate (second scraping plate) and the second packet or more is scraped out using the wide scraping plate (first scraping plate). However, even when the scraping width is 93 packets or less, which is greater than or equal to the width of the wide scraping plate (first scraping plate), the first packet can be scraped out using the narrow scraping plate (second scraping plate) and the second packet or more can be scraped out using the wide scraping plate (first scraping plate).

[0073] The present invention is not limited to the above embodiment, and can be modified or altered without changing the gist of the invention. For example, in the above embodiment, there are two first scraping plates (wide scraping plates 29a, 29b) and one second scraping plate (narrow scraping plate 29c), but there may be one first scraping plate and one second scraping plate.
