Description

  The present invention relates to a medicine packaging device.

  In a conventional medicine packaging device, for example, a medicine such as a powder or a tablet (including a powder contained in a capsule, the same applies hereinafter) supplied from a medicine supply mechanism is received from a hopper receiving port. There is a medicine packaging device that discharges the medicine from the outlet of the hopper to the medicine packaging mechanism.

  In such a conventional medicine packaging device, the discharge port of the hopper is usually disposed above or in the packaging sheet provided in the medicine packaging mechanism, and the medicine received from the receiving port of the hopper is received. It is supplied to the packaging sheet through the outlet of the hopper. At this time, all or a part of the medicine received from the hopper receiving port does not slide on the inner wall of the hopper between the receiving port and the discharge port, and passes through the inner space of the hopper and remains at a relatively high falling speed. May fall directly on the packaging sheet. For this reason, there is a problem in that the medicine that has dropped directly onto the packaging sheet jumps out of the packaging sheet, and particularly when the medicine is a powdered powder, the powder is scattered.

  Therefore, in a substantially inverted triangular hopper as viewed from the side, an inclined surface is provided between the receiving port for receiving the drug supplied from the drug supply mechanism and the discharge port for discharging the received drug to the drug packaging mechanism. A hopper having a partition plate provided therein has been proposed (see, for example, Patent Document 1).

  In this detection sensor 610, when there is no slit 351 between the light emitting unit 611 and the light receiving unit 612, light from the light emitting unit 611 to the light receiving unit 612 is blocked, so an OFF signal is sent to the control unit CONT to emit light. When there is a slit 351 between the light receiving unit 612 and the light receiving unit 612, light passes from the light emitting unit 611 to the light receiving unit 612, and an ON signal is sent to the control unit CONT. Thereby, since the control part CONT can detect the feed amount to the 1st horizontal direction X one side (X1 side in FIG.2 and FIG.3) of the bracket 300, in other words, the bracket 300 (in other words, tablet tablet 140 and A predetermined amount (here, the powder mass 242 on the most upstream side in the first movement direction X1) of the powder tablet 240) in a first movement direction X1 from the starting position T1 ′, which will be described later, to the first horizontal direction X one side, is described later. When the first movement direction X1 is moved, it can be reversed in the second movement direction (X2 direction in FIGS. 2 and 3) opposite to the first movement direction X1. Moreover, since the identification pitch P3 of the slits 351 is equal to the powder mass pitch P2 of the plurality of powder masses 242 in the powder tablet 240, the detection of the identification pitch P3 of the slits 351 can be detected as the powder mass pitch P2 in the powder tablet 240. .

  The bracket stop light detection sensor 630 is for detecting the bracket stop protrusion 370 and is disposed at a position corresponding to a position at which the bracket 300 is stopped. Further, the medicine loading position detection light detection sensor 640 is for detecting the medicine loading position detection protrusion 380 and is disposed at a position corresponding to the medicine loading position. These are all connected to the control unit CONT (see FIG. 8).

  Here, as shown in FIG. 4, each of the detection sensors 620 to 640 includes light emitting units 621 to 641 that emit light and light receiving units 622 to 642 that receive light emitted from the light emitting units 621 to 641. The starting position detecting protrusion 360 passes between the light emitting part 621 and the light receiving part 622, and between the light emitting parts 631, 641 and the light receiving parts 632, 642, the bracket stopping and drug injection position detecting protrusions. The parts 370 and 380 are provided so as to pass therethrough. The starting position T1 ′ of the bracket 300 is a position where the starting position detecting projection 360 blocks light between the light emitting part 621 and the light receiving part 622 of the detection sensor 620, and the inverted position of the bracket 300 is the bracket stop position. The projection 370 (380) for detection is set to a position where the light between the light emitting unit 631 and the light receiving unit 632 of the detection sensor 630 is blocked, and the drug loading position is detected by the projection 380 (370) for detecting the drug loading position. It is set as the position which blocks the light between the light emission part 641 and the light-receiving part 642.

  In each of the detection sensors 620 to 640, when there are protrusions 360 to 380 between the light emitting units 621 to 641 and the light receiving units 622 to 642, light from the light emitting units 621 to 641 to the light receiving units 622 to 642 is blocked. Therefore, when an OFF signal is sent to the control unit CONT and there are no projections 360 to 380 between the light emitting units 621 to 641 and the light receiving units 622 to 642, light is transmitted from the light emitting units 621 to 641 to the light receiving units 622 to 642. Since it passes, an ON signal is sent to the control part CONT. Thus, the control unit CONT sets the start position T1 ′ of the bracket 300 when the detection sensor 620 is OFF, the stop position of the bracket 300 when the detection sensor 630 is OFF, and further when the detection sensor 640 is OFF. The drug injection position can be detected.

Thus, the rotating member 263a" is centered on the third support shaft 263d in a predetermined direction (clockwise direction C1 or counterclockwise direction C2). As a result, the rotating member 263a rotates in the clockwise direction C1 or counterclockwise direction C2 in the figure, and accordingly, the first and second powdered valve operation units 261 and 262 are moved. The predetermined direction may be rotated in the reverse direction (counterclockwise direction C2 or clockwise C1).

  The first and second arm members 263b, 263c are both long plate-like members, and the first arm member 263b has one end portion 263b ′ having a rotation fulcrum shaft Q1 and a rotation member 263a ″ in the rotation member 263a ”. The other end 263b ″ is pivotally connected to the one end 263c ′ of the second arm member 263c by the pivot fulcrum axis Q2, and the other end 263c ″ of the second arm member 263c is connected to the powder valve. The movement adjusting mechanism 250 is bent along the second horizontal direction Y to the fourth support shaft 263e fixedly arranged at the lower right in the drawing of the rotating member 263a and bent with respect to the first arm member 263b. As a result, the second arm member 263c abuts on an eccentric cam 264 that rotates as will be described later, so that a predetermined direction about the fourth support shaft 263e is obtained. It is rotated in the clockwise direction C1 or counterclockwise direction C2), and accordingly, it is possible to rotate the rotating member 263a "clockwise C1 or counterclockwise direction C2 via the first arm member 263b. The second arm member 263c is provided with a cam contact roller 263f that is rotatably supported by the second arm member 263c on the fifth support shaft 263g at a portion that contacts the eccentric cam 264.

Further, the eccentric cam 264 is disposed below the second arm member 263c, and is described below as a rotational drive disposed along the second horizontal direction Y of the powdered valve operation mechanism drive unit 270. The eccentric cam 264 is rotated in the clockwise direction C1 or the counterclockwise direction C2 so that the second arm member 263c is biased by the biasing member 265 via the cam contact roller 263f. It can be rotated in the clockwise direction C1 against the force or in the counterclockwise direction C2 by the urging force of the urging member 265. In addition, the powdered valve initial position detection center is provided at a predetermined portion of the peripheral portion of the eccentric cam 264. Detection object 264a for detection by support 280 and the powdered medicine valves inclined position detection sensor 290 is provided.

  The powdered valve operation mechanism drive unit 270 is an eccentric cam rotation drive motor having a rotation drive shaft 271 arranged along the second horizontal direction Y, and is connected to the control unit CONT (see FIG. 8). . Thereby, the rotational drive shaft 271 is rotationally driven under the instruction of the control unit CONT, whereby the eccentric cam 264 connected to the rotational drive shaft 271 can be rotated in the clockwise direction C1 or the counterclockwise direction C2. .

  The powdered valve initial position detection sensor 280 and the powdered valve tilt position detection sensor 290 are both for detecting the detected body 264a in the eccentric cam 264, and are connected to the control unit CONT (see FIG. 8). . Among these, the powdered valve initial position detection sensor 280 is a detected object at a position where the first and second rotating portions 261b and 262b take a horizontal posture substantially parallel to the first horizontal direction X at the rotational position of the eccentric cam 264. H.264a is detected (see FIG. 7A), and the powdered valve inclination position detection sensor 290 is provided at the rotational position of the eccentric cam 264 at the first and second rotating portions 261b and 262b. The detected object 264a is placed at a position where it takes an inclined posture (in this example, an inclined posture of about 45 ° from the first horizontal direction X) from the horizontal posture to a vertical posture substantially perpendicular to the first horizontal direction X. It is disposed at a position where it can be detected (see FIG. 7B). In this example, under the instruction of the control unit CONT, the powdered valve initial position detection sensor 280 detects the detected body 264a and rotates it half a round so that the first and second rotating units 261b and 262b It is comprised so that the said vertical attitude | position can be taken (refer FIG.7 (C)).

  Here, the detection sensors 280 and 290 have push switch portions 281 and 291, respectively, and the detected body 264 a is provided so as to pass through the push switch portions 281 and 291. In these detection sensors 280 and 290, when the detected object 264a is not disposed in the push switch units 281 and 291 respectively, an OFF signal is sent to the control unit CONT, and the detected object 264a is transmitted to the push switch units 281 and 291. Is arranged, an ON signal is sent to the control unit CONT. Thereby, the control part CONT detects the rotation position of the 1st and 2nd rotation part 261b, 262b, The engagement part 241b ', 241b in powder medicine valve 241', 241 "is detected by the powder medicine valve operation mechanism 260. "Is rotated in the engaged state with the first and second powdered valve operating portions 261 and 262, respectively, so that the powdered valves 241 'and 241" are rotated with the rotation of the engaging portions 241b' and 241b ". However, the drive of the eccentric cam rotation drive motor 270 can be controlled so that the closed posture, the inclined posture, and the vertical posture can be taken.

  Here, when the medicine is supplied, the user selects the position of the powdered valve 241 ′, 241 ″ in the tilted position or the vertical position by the detection sensors 280, 290 by the user. It is made by operating the adjustment selection means 950. In this example, this powder valve opening adjustment selection means 950 is the powder valve opening degree arrange | positioned at the operation part 900 arrange | positioned at the top tablet 110. 8 and is connected to the control unit CONT as shown in Fig. 8. Thereby, selection information (selection signal) by the powdered valve opening adjustment selection switch 950 can be sent to the control unit CONT. When the opened powder valves 241 ′, 241 ″ are closed, the powder valves 241 ′, 241 ″ take the closed position. So as to control the driving of the sea urchin eccentric cam rotation driving motor 270. Accordingly, the powdered medicine valve 241 ', can give closed again 241 ".

  Further, in this medicine dispensing apparatus A1, the supply start position (that is, the open position) T1 of the tablet valve 141 by the tablet plate 151 of the tablet distribution processing mechanism 150 and the supply start position (that is, the powder valve 241 by the powder valve opening adjusting mechanism 250) (Open position) T1 is made substantially coincident.

  On the other hand, the drug hopper 410 can receive the drug from the tablet tablet 140 and the powder tablet 240 and supply the received drug to the packaging sheet H as shown in FIG.

  In addition to the drug hopper 410, the drug distribution device A1 includes a drug input unit 400, a tablet valve opening / closing mechanism 500, and a drive unit 700. As shown in FIG. 4, the drug supply unit 400 receives a tablet from the tablet tablet 140 and guides the received tablet to the drug hopper 410, and in the middle of an entry path from the tablet tablet 140, It has an open / close valve 430 that can be opened and closed in order to open or close the tablet, and a valve rotating shaft 431 that supports the open / close valve 430.

  The valve rotation shaft 431 is supported by a support member (not shown) so as to be rotatable around the axis, and is provided with a valve arm 431a. Thereby, the on-off valve 430 and the valve arm 431a can be rotated together.

  The tablet valve opening / closing mechanism 500 includes a solenoid arm 510 and a link member 520. One end of the solenoid arm 510 and one end of the link member 520 are supported by the fulcrum part 530, and the other end of the link member 520 and one end of the valve arm 431a are supported by the fulcrum part 540, respectively. The other end is connected to a solenoid rotating shaft 711 of a solenoid 710 in the driving unit 700 described later. Accordingly, the opening / closing valve 430 can be opened via the tablet valve opening / closing mechanism 500 by rotating the solenoid rotating shaft 711 of the solenoid 710 counterclockwise in the drawing, while the solenoid rotating shaft 711 of the solenoid 710 is opened in the drawing. The opening / closing valve 430 can be closed via the tablet valve opening / closing mechanism 500 by rotational driving in the direction.

  The driving unit 700 includes the solenoid 710. The solenoid 710 is connected to the control unit CONT (see FIG. 8), and can rotate the solenoid rotating shaft 711 by a predetermined amount under the instruction of the control unit CONT.

  FIG. 8 shows a schematic block diagram of the control unit CONT in the medicine packaging device A shown in FIG. As shown in FIG. 8, the control unit CONT is connected to the medicine distribution device A1 and the medicine packaging device A2, and includes detection sensors 610 to 640, a powder valve opening adjustment selection switch 950, and a powder valve initial position detection sensor 280. Based on input signals from the powder valve tilt position detection sensor 290, the medicine packaging device A2, etc., the operations of the solenoid 710, the bracket feed motor 810, the eccentric cam rotation drive motor 270, the medicine packaging device A2, etc. are controlled. Can do. Then, the control unit CONT controls the drive of the eccentric cam rotation drive motor 270 so that the vertical posture can be taken after a lapse of a predetermined time after dropping the medicine with the powder valves 241 ′, 241 ″ tilted. Including means.

  In the medicine packaging apparatus A described above, in the medicine packaging operation, the bracket 300 on which the tablet tablet 140 and the powder tablet 240 are mounted is arranged at the medicine loading position by the detection of the protrusion 380 by the detection sensor 660. Then, as shown in FIG. 1, the tablet is put into the opening 111 of the top tablet 110 of the tablet supply mechanism 100, and the powder is put into the powder storage part S of the powder supply mechanism 200. Also, the powder charged from the storage part S of the powder supply mechanism 200 falls to the powder tablet 240 by opening the lower part of the storage part by the movement of the movable plate S1.

  Next, for example, the medicine is ejected or scattered as the opening posture of the powder valves 241 ′, 241 ″ by the powder valve opening adjustment mechanism 250 by the powder valve opening adjustment selection switch 950 disposed on the top tablet 110. The tilted posture is selected when it is considered that the influence of the drug is relatively large, and the vertical posture is selected when the drug is thought to be hardly affected by the jumping out or scattering.

  The control unit CONT instructs the bracket feed motor 810 to drive, rotates the motor shaft 811, and moves the bracket 300 equipped with the tablet tablet 140 and the powder tablet 240 in the first movement direction X1. Accordingly, the bracket 300 on which the tablet tablet 140 and the powder tablet 240 are mounted is disposed at the start position T1 'corresponding to the supply start position T1 by the detection of the protrusion 360 by the detection sensor 620. The starting position T1 ′ is the position at which the tablet plate 151 of the tablet distribution processing mechanism 150 opens the tablet valve 141 in the first row and the powder valve operating mechanism 260 of the powder valve opening adjusting mechanism 250. The position of the first movement direction X1 is about one pitch of the powder mass pitch P2 from the position at which the powder valve 241 in the first row is opened.

  When the start of packaging is instructed, the control unit CONT moves the bracket 300 equipped with the tablet tablet 140 and the powder tablet 240 further in the first movement direction X1 from the start position T1 'in the packaging operation. At this time, the detection sensor 610 is monitoring the slit part 350 and sends the detection signal to the control part CONT.

  Upon receiving the detection signal from the detection sensor 610, the control unit CONT recognizes the powder supply position of the powder mass 242 and the tablet 300 and the bracket 300 equipped with the powder tablet 240 are moved from the starting position T1 ′ to the powder mass pitch P2. At this supply position (here, the supply position every time the powdered mass pitch P2 is moved from the supply start position T1), the bracket feed motor 810 is instructed to stop driving, and the bracket 300 is temporarily stopped. As described above, the medicine dispensing apparatus A1 moves the bracket 300 intermittently at the powder mass pitch P2 of the plurality of powder masses 242 to the first horizontal direction X one side X1, thereby integrally integrating the tablet tablet 140 and the powder tablet 240. It can be moved intermittently at the powder mass pitch P2.

  At this time, in the powder supply mechanism 200, the powder tablet 240 having the plurality of powder masses 242 moves the powder mass pitch P2 to the first horizontal direction X one side X1, so that the first powder powder in the powder valve opening adjustment mechanism 250 The valve operating part 261 is engaged with the engaging part 241b ′ of the corresponding one powdered valve 241 ′ according to the powdered mass pitch P2 in the first horizontal direction X one side X1, and the control part CONT is used for the eccentric cam. By instructing the rotation drive motor 270 and rotating the motor 270, the first and second powdered valve operation portions are rotated by the rotation of the eccentric cam 264 and the rotation of the rotation member 263 a accompanying the rotation of the operation arm mechanism 263. The pair of first and second rotating portions 261b and 262b are rotated by the rotation of the pair of first and second rotating portions 261b and 262b. With the rotation of the engaging portion 241b ′ in the engaged state sandwiched between the rotating portions 261b and 262b, the powdered valve 241 ′ is opened. When the inclined posture is selected as the posture of the valve 241 ′, the powdered valve 241 ′ takes the inclined posture. In this example, the powder valve 241 ′ takes the vertical posture after a predetermined time has elapsed after dropping the medicine in an inclined state. In addition, when the user selects the vertical posture, the powder valve 241 ′ takes the vertical posture, and the powder drops from the powder mass 242. Thus, the powder falling from the powder mass 242 passes through the drug hopper 410 and is supplied to the packaging sheet H.

  On the other hand, in the tablet supply mechanism 100, the tablet F falls from the tablet mass 142. Then, the dropped tablet F is guided toward the medicine hopper 410 by the tablet guide member 420. At this time, the opening / closing valve 430 is in a closed state, and the tablet F passing through the tablet guide member 420 is received by the opening / closing valve 430 and does not reach the packaging sheet H. The control unit CONT instructs the solenoid 710 to drive, rotates the rotating shaft 711 counterclockwise in FIG. 4, and opens the opening / closing valve 430 with the tablet valve opening / closing mechanism 500. Then, the tablet F received by the opening / closing valve 430 passes through the medicine hopper 410 and is supplied to the packaging sheet H. Thus, the tablet valve opening / closing mechanism 500 closes the opening / closing valve 430 prior to the movement of the bracket 300 each time the bracket 300 moves the powder mass pitch P2 of the plurality of powder masses 242 in the first horizontal direction X one side X1. After the powder E passing through the powder entry path from the powder tablet 240 is supplied to the packaging sheet H, the opening / closing valve 430 can be opened.

  Thereafter, the control unit CONT instructs the medicine packaging apparatus A2 to perform the medicine packaging operation. The medicine packaging apparatus A2 instructed to wrap the medicine by the control unit CONT performs the heat seal H1 on the packaging sheet H to which the powder and tablets are supplied to form the individually divided package H2, and the next powder. And in order to supply a tablet, the packaging sheet H is moved for one package body, and it prepares for the next chemical | medical agent supply.

  Next, the control unit CONT instructs the solenoid 710 to drive prior to the movement of the bracket 300 in the first horizontal direction X one side X1, and rotates the rotary shaft 711 in the clockwise direction in FIG. Is closed by the tablet valve opening / closing mechanism 500.

  Thereafter, the control unit CONT instructs the bracket feed motor 810 to drive, rotates the motor shaft 811, and further moves the bracket 300 equipped with the tablet tablet 140 and the powder tablet 240 in the first movement direction X 1 in the powder movement mass pitch P 2. . Then, in the powder supply mechanism 200, the powder tablet 240 having a plurality of powder masses 242 moves the powder mass pitch P2 to the first horizontal direction X one side X1, so that the first powder valve opening adjustment mechanism 250 has the first powder valve. The operating part 261 is engaged with the engaging part 241b ′ of the corresponding one powdered valve 241 ′ according to the powdered mass pitch P2 toward the first horizontal direction X one side X1, and the second powdered valve operating part 262 is engaged. Is engaged with the engaging portion 241b ″ of the powdered valve 241 ″ (powdered valve previously opened) adjacent to the other side X2 of the first horizontal direction X from the powdered valve 241 ′, and the control unit CONT is used for the eccentric cam. By instructing the rotation drive motor 270 and rotating the motor 270, the rotation operation of the eccentric cam 264 and the rotation of the operation arm mechanism 263 are performed. The first and second powdered valve operating portions 261 and 262 are rotated by the rotation of the rotating member 263a according to the operation, and thereby the pair of first and second rotating portions 261b and 262b are rotated to thereby rotate the pair of the first and second powdered valve operating portions 261b and 262b. With the rotation of the engaging portions 241b ′ and 241b ″ in the engaged state sandwiched between the first and second rotating portions 261b and 262b, the powder valves 241 ′ and 241 ″ are opened (the powder valve 241 ′ For example, if the user selects the tilted posture as the posture of the powdered valves 241 ′, 241 ″ with the powdered valve opening adjustment switch 950, the powdered valve 241 is used for the first time. ', 241 "takes the inclined posture. In this example, the powder valve 241', 241" takes the vertical posture after a predetermined time has elapsed after dropping the medicine in the inclined state. Take. When the user selects the vertical posture, the powder valves 241 ′ and 241 ″ take the vertical posture, and the powder drops from the powder mass 242. Thus, the powder dropped from the powder mass 242 is the drug hopper 410. Is supplied to the packaging sheet H. Hereinafter, the operations described above from the third row to the 21st row for powder and from the first row to the third row to the seventh row for the tablet are as described above. The same operation is repeated.

  When the packaging operation is completed, the control unit CONT instructs the solenoid 710 to drive, rotates the rotating shaft 711 counterclockwise in FIG. 4, and opens the opening / closing valve 430 by the tablet valve opening / closing mechanism 500. Let Thereafter, the bracket 300 is reversed, and the bracket 300 is stopped at the starting position T1 'by detecting the protrusion 360 by the detection sensor 620, and is prepared for the next medicine packaging.

  As described above, in the medicine packaging device A, the powder supply mechanism 200 having the plurality of powder masses 242 is moved to the supply start position T1 and then the first horizontal direction X one side X1 when the powder is packaged. Each time the powder mass P2 is moved, the powder is sequentially dropped from the plurality of powder masses 242 downward. Here, if the drug (particularly fine powder of highly scattered powder) is moved directly from the drug supply mechanism to the drug packaging mechanism as in the conventional drug packaging device, the drop distance of the drug in the vertical direction is increased accordingly. In the device A of the present embodiment, when the powder is dropped downward, the powder valve opening adjustment mechanism 250 causes the first horizontal direction of the powder valves 241 in the plurality of powder masses 242 to fall. For one powdered valve 241 ′ corresponding to the powdered mass pitch P2 to the X one side X1, as shown in FIG. 7 (A), the opening posture is adjusted, and the drug is once collided with the inner wall of the hopper 410. By dropping the packaging sheet H, the total drop distance in the vertical direction of the medicine is shortened, that is, as shown in FIG. This is the total distance of the vertical distance L1 up to 0 and the vertical distance L2 from the hopper 410 to the packaging sheet H. In other words, the distance L3 of the inclined portion that slides on the hopper 410 is shortened. Since the vertical drop speed at the time of rushing into the packaging sheet H can be suppressed, the jumping out and scattering of the powder can be suppressed. Further, by taking the open posture while the powder valve 241 ′ is tilted, the amount of drug per unit time that passes between the lower opening of the powder mass 242 and the powder valve 241 ′ is limited. Therefore, this action can also prevent the drug from jumping out and scattering.

  As described above, according to the medicine packaging apparatus A, a plurality of powder supply mechanism 200 is provided in the powder supply mechanism 200 without providing a member such as a partition plate in the hopper 410 that obstructs the passage route of the medicine. By simply adjusting the opening posture of the powder valve 241 in the powder mass 242, it is possible to suppress the spraying and scattering of the powder.

  The second powder valve operation unit 262 may be removed and only the first powder valve operation unit 261 may be provided, but the first and second powder valve operation units 261 and 262 may be provided as in this example. Each time the bracket 300 on which the powder tablet 240 is mounted moves to the first horizontal direction X one side X1, the powder valves 241 ′ and 241 ″ are opened in sequence two times each time the powder mass P2 of the plurality of powder masses 242 moves. Thus, for example, it is advantageous in the following case: That is, the powder valve 241 is opened first time by opening two powder valves 241 in turn (in other words, the powder valve 241 is opened twice). The medicine that may remain in the 241 can be collected in the next package, and the powder loaded from the container S of the powder supply mechanism 200 is moved downward by the movable plate S1. When falling to the powder tablet 240 by opening, the powder at the both ends of the first horizontal direction X of the container S is likely to spill outside the both ends of the first horizontal direction X of the powder tablet 240, as shown in FIG. The medicine packaging device A is configured such that the openings at both ends of the first horizontal direction X of the accommodating part S are widened at the top on both outer sides of the plurality of powder masses 242 in the first horizontal direction X. In addition to the configuration, as shown in FIG. 10, the powder tablet 240 is configured such that the powders at both ends of the first horizontal direction X of the accommodating portion S are received on both outer sides of the first horizontal direction X of the plurality of powder masses 242. Left and right powder receiving masses 242b and 242c are provided. For example, when the powders in the first row of powdered masses 242 out of a plurality of powdered masses 242 are packaged, Mass 2 When the powder of 2b and the powdered mass 242 of the first row is dropped, the packaging sheet H is packaged, and when the powdered powder of the powdered mass 242 of the 21st row is packaged, the powdered powder of the first row After dropping the powder of the mass 242 and the right powder receiving mass 242b, the packaging sheet H may be packaged so that the powder at the both ends of the first horizontal direction X can be reliably packaged. it can.

  Further, in this example, the control unit CONT controls the drive of the eccentric cam rotation drive motor 270 so that the vertical posture can be taken after a predetermined time has elapsed after dropping the medicine with the powder valve 241 tilted. Therefore, when the medicine is dropped with the powder valve 241 tilted, the medicine that may remain in the powder valve 241 can be reliably dropped. Further, the control unit CONT can select whether the powder valve 241 is tilted and rotated so that the tilted open posture can be taken or whether the powder valve 241 can be vertically rotated so that the vertical posture can be taken. Since the drive of the cam rotation drive motor 270 is controlled, more specifically speaking, depending on the type of drug (for example, high / low degree of scatter), the drug is highly scatterable granules / fine particles, etc. In some cases, it can be selected to rotate the tilt, and in the case where the drug is a powdered granule / tablet or the like having a low scattering property, the vertical rotation can be selected.

  In this example, every time the bracket 300 with the powder tablet 240 is moved to the first horizontal direction X one side X1 by the powder valve opening adjustment mechanism 250, the powder mass 242 is moved in the first row. After opening the powdered valves 241 ′, 241 ″ in order from the first to the k-th column (here, the 21st column), the heat-seal device 10 is configured to wrap the packaging sheet H. Each time the bracket 300 equipped with the powder tablet 240 is moved in the first horizontal direction X one side X1 by the powder valve opening adjustment mechanism 250 at a pitch twice the powder mass pitch P2 of the plurality of powder masses 242, the first row. To the k-th row (here, the 21st row), the powdered valves 241 ′ and 241 ″ are opened in order, and then the packaging sheet H is packaged by the heat seal device 10. Sea urchin may be configured. In this case, the powder for two powder masses 242 is packaged in one package H2.
