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).

The first and second starting positions T1 ′ and T2 ′ of the bracket 300 are such that the starting position detecting projection 360 has the light emitting parts 631 and 641 and the light receiving parts 632 and 642 of the first and second detection sensors 630 and 640. The position where the bracket 300 is inverted is the position where the bracket stopping projection 370 (380) blocks the light between the light emitting part 651 and the light receiving part 652 of the detection sensor 650, and the medicine The insertion position is a position where the drug insertion position detection projection 380 (370) blocks light between the light emitting unit 661 and the light receiving unit 662 of the detection sensor 660.

  In each of the detection sensors 630 to 660, when there are protrusions 360 to 380 between the light emitting parts 631 to 661 and the light receiving parts 632 to 662, light from the light emitting parts 631 to 661 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 631 to 661 and the light receiving units 632 to 662, light is transmitted from the light emitting units 631 to 661 to the light receiving units 632 to 662. Since it passes, an ON signal is sent to the control part CONT. Accordingly, the control unit CONT sets the first and second start positions T1 ′ and T2 ′ of the bracket 300 when the detection sensors 630 and 640 are OFF, and the stop position of the bracket 300 when the detection sensor 650 is OFF. Further, when the detection sensor 660 is OFF, the medicine loading position can be detected. It should be noted that which of the detection sensors 630 and 640 is selected for detection, in other words, one of the first and second supply start positions T1 and T2 of the tablet supply mechanism 100 and the powder supply mechanism 200.

  As shown in FIG. 7B, the valve opener 251 includes an arm portion 251a and a contact portion 251b. The arm portion 251a is disposed outside the operation tab 241b of the powdered valve 241. The contact portion 251b protrudes from the arm portion 251a toward the operation tab 241b so as to contact the operation tab 241b. Accordingly, the contact portion 251b of the valve opener 251 can be brought into contact with the operation tab 241b each time the bracket 300 moves in the first horizontal direction X one side X1 of the powder mass 242. The powder valves 241 can be sequentially opened one by one from the first row to the 21st row. At this time, since the arm portion 251a of the valve opener 251 is arranged outside the operation tab 241b of the powdered valve 241, collision with the operation tab 241b due to movement of the bracket 300 of the arm portion 251a in the X1 direction is avoided. be able to.

  The valve closing member 252 is brought into contact with the powdered valve 241 at a position corresponding to the powdered valve 241 opened by the valve opener 251 by the movement of the powdered tablet 240 in the first horizontal direction X one side X1. The valve 241 is closed.

  More specifically, the valve closing member 252 is a roller in this case, and the contact position of the contact portion 251b of the valve opener 251 with the operation tab 241b so that the roller axial direction is in the second horizontal direction Y. It is arranged slightly lower (see FIG. 7A). Thereby, the powdered valve 241 opened by the movement of the bracket 300 in the first movement direction X1 can be closed again by the movement of the bracket 300 in the X1 direction.

  FIG. 8 is a view showing a process of opening and closing the powdered valve 241. FIG. 8A shows a start position corresponding to the supply start position selected by the supply start position selection switch 950 among the first and second supply start positions T1 and T2 of the powder tablet 240 (in the illustrated example, the first start position).

At this time, the powder distribution processing mechanism 250 is disposed at the first swing position T3. When the powder tablet 240 moves in the first movement direction X1, as shown in FIGS. 8C and 8D, the contact portion 251b of the valve opener 251 contacts the operation tab 241b of the powder valve 241; As a result, the powder valve 241 of the first row mass is opened. When the powder tablet 240 further moves in the first movement direction X1, as shown in FIG. 8E, the opened first row mass powder valve 241 is closed by the valve closing roller 252 and the next second The contact portion 251b of the valve opener 251 is brought into contact with the operation tab 241b of the row mass powder valve 241, thereby opening the second row mass powder valve 241. This operation is repeated up to the powder valve 241 of the 21st row mass. Note that the case where the powder tablet 240 is disposed at the second starting position T2 'is substantially the same as the case of the first starting position T1', and the description thereof is omitted here.

  Further, in this medicine dispensing apparatus A1, the first or second supply start position (that is, the open position) T1, T2 of the tablet valve 141 by the tablet plate 151 of the tablet dispensing processing mechanism 150 and the valve opener 251 of the powder dispensing processing mechanism 250 are used. The first or second supply start position (that is, the open position) T1 and T2 of the powdered valve 241 are substantially coincided with each other.

  Furthermore, as shown in FIG. 7 (A), the powder distribution processing mechanism 250 has a predetermined interval between the contact position α of the valve opener 251 with the operation tab 241b and the retracted position β for retracting from the corresponding contact position α. It is configured to selectively arrange at timing.

  The arm portion 251a of the valve opener 251 is rotatably supported by a fulcrum portion 255, and the contact portion 251b is moved to the retracted position β by the biasing member 253 at the end portion 251c opposite to the contact portion 251b. It is urged to rotate in the counterclockwise direction B2 in FIG.

  On the other hand, as shown in FIG. 9, the drug hopper 410 can receive the drugs from the tablet tablet 140 and the powder tablet 240 and supply the received drug to the packaging sheet H. The drug supply unit 400 receives the tablet from the tablet tablet 140 and guides the received tablet to the drug hopper 410, and opens or blocks the tablet in the course of the entry path from the tablet tablet 140. And an open / close valve 430 that can be freely opened and closed, 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 as shown in FIG. 7A, an opening / closing valve 430 is provided at one end and the other end is provided. A cam 254 is provided, and a valve arm 431 a is further provided between the valve 430 and the cam 254. Thereby, the on-off valve 430, the cam 254, and the valve arm 431a can be rotated integrally.

  As shown in FIGS. 7 and 10, the drive unit 700 includes a solenoid 710. The solenoid 710 is connected to the control unit CONT (see FIG. 11), and can rotate the solenoid rotation shaft 711 in a clockwise direction C1 or a counterclockwise direction C2 in FIG. 10 under the instruction of the control unit CONT.

  The 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 a fulcrum part 530, and the other end of the link member 520 and one end of the valve arm 431a are rotatably supported by a fulcrum part 540, respectively. The other end is connected to the solenoid rotating shaft 711 of the solenoid 710.

  Thereby, the opening / closing valve 430 can be opened via the valve opening / closing mechanism 500 by the rotational driving of the solenoid rotating shaft 711 of the solenoid 710 in the direction C2 in FIG. 10 (see FIG. 7A). At this time, the cam 254 integral with the opening / closing valve 430 rotates by a predetermined amount in the direction C1 in FIG. 10, and the end 251c opposite to the contact portion 251b of the valve opener 251 is applied by the urging force of the urging member 253. The valve opener 251 is pushed down, that is, the valve opener 251 is rotated by a predetermined amount in the direction B2 in FIG. 7A. Therefore, the contact portion 251b of the valve opener 251 is disposed at the retraction position β where the contact portion 251b is retracted from the contact position α with the operation tab 241b. Can be made.

  On the other hand, the opening / closing valve 430 can be closed via the valve opening / closing mechanism 500 by rotating the solenoid rotating shaft 711 of the solenoid 710 in the direction C1 in FIG. 10 (see FIG. 7B). At this time, the cam 254 integral with the opening / closing valve 430 rotates by a predetermined amount in the direction C2 in FIG. 10, and the end 251c of the valve opener 251 is pushed up against the biasing member 253 by the cam 254, that is, the valve opener 251. 7A is rotated by a predetermined amount in the B1 direction in FIG. 7A, the contact portion 251b of the valve opener 251 can be disposed at the contact position α with the operation tab 241b. Thus, the valve opener 251 can swing at a predetermined timing between the contact position α with the operation tab 241b and the retreat position β withdrawn from the corresponding contact position α based on an instruction from the control unit CONT. it can.

  As described above, in the medicine dispensing device A1, when the valve opening / closing mechanism 500 closes the opening / closing valve 430, the powder dispensing processing mechanism 250 places the valve opener 251 at the contact position α with the operation tab 241b, and the valve opening / closing mechanism 500 When the opening / closing valve 430 is opened, the powder distribution processing mechanism 250 is disposed at the retracted position β where the valve opener 251 is retracted from the contact position α, thereby opening / closing the opening / closing valve 430 and disposing the valve opener 251. It is configured to perform the driving by 700.

  FIG. 11 shows a schematic block diagram of the control unit CONT in the medicine packaging device A shown in FIG. As shown in FIG. 11, the control unit CONT is connected to the medicine distribution device A1 and the medicine packaging device A2, and inputs from the detection sensors 610 to 660, the supply start position selection switch 950, the medicine packaging device A2, and the like. Based on the signal, the operations of the solenoid 710, the bracket feed motor 810, the powder distribution processing mechanism swing device 910, the tablet distribution processing mechanism swing device 920, the medicine packaging device A2, and the like can be controlled.

  In the medicine packaging apparatus A including the medicine dispensing apparatus A1 described above, the bracket 300 on which the tablet tablet 140 and the powder tablet 240 are mounted is detected by the detection sensor 660 by the projection 380 in the medicine packaging operation. Placed in. 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, as a supply start position of the medicine supply mechanisms 100 and 200 by the supply start position selection switch 950 disposed on the top tablet 110, for example, the user thinks that the influence of the medicine is relatively large. The first supply start position T1 is selected in the case where the medicine is to be discharged, and the second supply start position T2 is selected in the case where the drug is considered to have almost no influence of the jumping out or scattering. Note that FIGS. 12 to 16 to be described later show an operation state when the first supply start position T1 is selected.

  Hereinafter, the case where both powder E and tablet F are packaged in each package H2 will be described. FIG. 12 shows the state of the first starting position T1 'of the medicine dispensing apparatus A1, and FIG. 13 shows the state before the start of the packaging operation. 12 and 13, FIG. (A) shows an operation example seen from the plane, FIG. (B) shows an operation example seen from the front, and FIG. (C) shows an operation example seen from the right side. . The same applies to FIGS. 14 to 16 described later.

  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. Thereby, the bracket 300 to which the tablet tablet 140 and the powder tablet 240 are attached is, as shown in FIG. 12, the first start position T1 corresponding to the first supply start position T1 by the detection of the protrusion 360 by the first detection sensor 630. Placed in '. At this time, both the tablet distribution processing mechanism 150 and the powder distribution processing mechanism 250 are arranged at the first swing position T3 corresponding to the first supply start position T1. The first starting position T1 ′ is a position at which the tablet plate 151 of the tablet distribution processing mechanism 150 opens the first-stage first-stage tablet valve 141 (tablet valve indicated by the slanted line in FIG. 12A). The first movement direction X1 upstream of the powder mass pitch P1 by one pitch from the position where the valve opener 251 of the powder distribution processing mechanism 250 opens the first row of powder valves 241 (the powder valve indicated by the hatching in FIG. 12A). And position.

  At this time, the solenoid 710 is rotated by a predetermined amount in the direction C2 as shown in FIG. 12C (see also FIG. 10A), and the opening / closing valve 430 is moved by the valve opening / closing mechanism 500. The contact portion 251b of the valve opener 251 is placed in the retracted position β by the powder distribution processing mechanism 250.

  When the start of packaging is instructed, the controller CONT first instructs the solenoid 710 to drive and rotate as shown in FIG. 13C (see also FIG. 10B) in the packaging operation. The shaft 711 is rotationally driven in the direction C1 in the drawing, the open / close valve 430 is closed by the valve open / close mechanism 500, and the contact portion 251b of the valve opener 251 is disposed at the contact position α by the powder distribution processing mechanism 250. .

  Next, the control unit CONT moves the bracket 300 equipped with the tablet tablet 140 and the powder tablet 240 further from the first starting position T1 'in the first movement direction X1. At this time, of the detection sensors 610 and 620, the detection sensor 610 corresponding to the first supply start position T1 monitors 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 on which the powder tablet 240 is mounted move from the first start position T1 ′ to the powder mass pitch P2. The bracket 300 is temporarily stopped by instructing the bracket feed motor 810 to stop driving at the medicine supply position (here, the supply position every time the powder mass pitch P2 is moved from the first supply start position T1). 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 is comprised so that it may move intermittently with powdered mass pitch P2.

  By the movement of the bracket 300 to which the tablet tablet 140 and the powder tablet 240 are attached in the first movement direction X1, the tablet valve 141 of the tablet mass 142 in the first row and the first stage and the powder valve of the powder mass 242 in the first row. 241 is opened, and powder E falls from powder mass 242 and tablet F falls from tablet mass 142.

  FIG. 14 to FIG. 16 are diagrams for explaining an example of the operation of packaging both powder E and tablet F in each package H2.

  The powder E falling from the powder mass 242 passes through the drug hopper 410 and is supplied to the packaging sheet H as shown in FIG. On the other hand, the tablet F dropped from the tablet mass 142 is guided to the medicine hopper 410 by the tablet guide member 420. At this time, as shown in FIGS. 14 (B) and 14 (C), the opening / closing valve 430 is closed, so that the tablet F passing through the tablet guide member 420 is received by the opening / closing valve 430, and the packaging sheet H has not been reached.

  Next, as shown in FIG. 15C (see also FIG. 10A), the control unit CONT instructs the solenoid 710 to drive, and rotationally drives the rotary shaft 711 in the direction C2 in the drawing, thereby opening and closing the valve 430. Is opened by the valve opening / closing mechanism 500 and the contact portion 251b of the valve opener 251 is disposed at the retracted position β by the powder distribution processing mechanism 250. 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 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 300 is supplied to the packaging sheet H by the movement of the bracket 300 and the powder E passing through the powder ingress path from the powder tablet 240 is supplied to the packaging sheet H, the open / close valve 430 is opened.

  Thereafter, the control unit CONT instructs the medicine packaging apparatus A2 to perform the medicine packaging operation. As shown in FIG. 16, the medicine packaging apparatus A2 instructed to wrap medicine by the control unit CONT performs heat sealing H1 on the packaging sheet H supplied with the powder E and the tablets F, and individually packaged packages. While forming H2, in order to supply the next powder E and tablet F, the packaging sheet H is moved by one package in the W direction in FIG. 16 (B) to prepare for the next medicine supply.

  Next, as shown in FIG. 16C (see also FIG. 10B), the control unit CONT instructs the solenoid 710 to drive the bracket 300 in the first horizontal direction X one side X1. Then, the rotary shaft 711 is rotated in the C1 direction in the drawing, the open / close valve 430 is closed by the valve open / close mechanism 500, and the contact portion 251b of the valve opener 251 is contacted by the powder distribution processing mechanism 250 at the contact position α. To be placed.

  Thereafter, the control unit CONT instructs the bracket feed motor 810 to drive, and rotates the motor shaft 811 to move the bracket 300 with the tablet tablet 140 and the powder tablet 240 attached thereto in the first movement direction X1 as shown in FIG. Is further moved to powder mass pitch P2. Thereafter, the same operations as those described above are repeated for the powder E from the second column to the twenty-first column and for the tablet F from the first column, the second column to the seventh column, the third column.

  When the packaging operation is completed, the control unit CONT instructs the solenoid 710 to drive, rotates the rotating shaft 711 in the direction C2 as shown in FIG. 10A, and causes the opening / closing valve 430 to move to the valve opening / closing mechanism 500. The contact portion 251b of the valve opener 251 is placed at the retracted position β by the powder distribution processing mechanism 250. Thereafter, the bracket 300 is reversed, and the bracket 300 is stopped at the first starting position T1 'by detecting the protrusion 360 by the detection sensor 630, and is prepared for the next medicine packaging. Although the operation at the first supply start position T1 has been described here, the operation at the second supply start position T2 is substantially the same as the operation at the first supply start position T1 except that the supply start position is different. There is no explanation here.

  As described above, in the medicine distribution device A1, when the medicines E and F are packaged, the medicine supply mechanisms 100 and 200 having the plurality of distribution rods 142 and 242 are moved to the supply start position. At this time, there are a plurality of supply start positions of the medicine supply mechanisms 100 and 200, and any one of the plurality of supply start positions T1 and T2 is selected. When the hopper 410 is a substantially inverted triangular hopper when viewed from the side as in this example, an arbitrary position above the inclined surface 413 in the hopper 410 is set in advance as the supply start position, and the receiving port of the hopper 410 is received. When the medicines E and F received from 411 are supplied to the medicine packaging mechanism 10 through the discharge port 412 of the hopper 410, the supply start position T1 is selected as the position above the inclined surface 413, so that the medicines E and F All or a part of F once collides with the inclined surface 413. 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 apparatus A1 of the present embodiment, the supply start position T1 is selected at an arbitrary position above the inclined surface 413, and all or a part of the medicines E and F are once collided with the inclined surface 413. Thus, the total vertical drop distance of the drugs E and F is shortened, that is, the vertical drop distance of the drugs E and F is the vertical distance L1 to the hopper 410 as shown in FIG. And the distance L2 in the vertical direction 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 head H can be suppressed, the medicines E and F can be sufficiently prevented from jumping out and scattering.

  Thereafter, every time the medicine supply mechanisms 100 and 200 are moved to the one side in the first direction X by the reference pitch P2, the medicines E and F are sequentially dropped from the plurality of distribution baskets 142 and 242, respectively. At this time, each stop position after movement of the medicine supply mechanisms 100 and 200 is an integer multiple of the reference pitch P2 from the selected first supply start position T1, and the inclined surface 413 of the hopper 410 is in any case. Since all or a part of the medicines E and F once collide with the inclined surface 413, the total falling distance of the medicines E and F in the vertical direction is shortened, and as a result, The medicine is supplied to the medicine packaging mechanism 10 in a state where the vertical drop speed when entering the medicine packaging mechanism 10 is lowered. Thereby, jumping out and scattering of the medicines E and F can be sufficiently suppressed. The drug packaging mechanism 10 disposed below the drug supply mechanisms 100 and 200 packages the drugs E and F supplied from the drug supply mechanisms 100 and 200.

  As described above, according to the medicine packaging apparatus A shown in FIG. 1, a plurality of medicine supply mechanisms 100 and 200 are provided without providing a member such as a partition plate or the like in the hopper 410 that obstructs the passage route of the medicines E and F. By simply selecting any one of the supply start positions T1 and T2, the jumping out and scattering of the medicines E and F can be suppressed.

  Next, another embodiment of the medicine packaging device according to the present invention will be described with reference to FIGS. In this medicine packaging device, in the medicine packaging device described above, instead of the medicine dispensing device A1, the structure of the medicine supply mechanism 200 and the like are changed, and the powder dispensing processing mechanism swinging device 280 is removed, thereby removing the powder dispensing processing.

In these detection sensors 280 and 290, when the detected object 264a is not arranged in the push switch sections 281 and 291 respectively, an OFF signal is sent to the control section CONT ′ and the detected objects are detected in the push switch sections 281 and 291. When H.264a is arranged, an ON signal is sent to the control unit CONT ′. As a result, the control unit CONT ′ detects the rotation positions of the first and second rotation units 261b and 262b, so that the powder valve operation mechanism 260 causes the engagement unit 241b ′ in the powder valves 241 ′ and 241 ″ to be engaged. By rotating in the engaged state with the first and second powdered valve operating portions 261 and 262, respectively, the powdered valves 241 ′ and 241 ″ are moved to the closed posture with the rotation of the engaging portion 241b ′. The drive of the eccentric cam rotation drive motor 270 can be controlled so that the inclined posture and the vertical posture can be taken. When the opened powdered valves 241 'and 241 "are closed, the drive of the eccentric cam rotary drive motor 270 is controlled so that the powdered valves 241' and 241" take the closed posture. As a result, the powdered valves 241 'and 241 "can be closed again.

  In the medicine packaging apparatus provided with the medicine dispensing apparatus A1 ′ described above, the controller CONT ′ drives the bracket feed motor 810 to drive the powder E and the tablets F in the individual packaging bodies H2. The motor shaft 811 is rotationally driven to move the bracket 300 on which the tablet tablet 140 and the powder tablet 240 ′ are mounted in the first movement direction X1. Accordingly, the bracket 300 on which the tablet tablet 140 and the powder tablet 240 ′ are mounted has the first start position corresponding to the first supply start position T1 or the second supply start position T2 by the detection of the protrusion 360 by the first detection sensor 630. It is arranged at T1 ′ or the second starting position T2 ′. At this time, the tablet distribution processing mechanism 150 is disposed at the first swing position T3 or the second swing position T4 corresponding to the first supply start position T1 or the second supply start position T2. The first starting position T1 ′ or the second starting position T2 ′ includes a 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 distribution processing mechanism 250 ′. The valve operating unit 261 is positioned about one pitch of the powder mass pitch P2 upstream of the first movement direction X1 from the position where 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 ′ from the first starting position T1 ′ or the second starting position T2 ′ in the packaging operation. Further, it is moved in the first movement direction X1. At this time, the detection sensors 610 and 620 corresponding to the first supply start position T1 or the second supply start position T2 of the detection sensors 610 and 620 monitor the slit portion 350, and the detection signal is transmitted to the control unit CONT ′.
