Description

  The present invention relates to a medicine packaging apparatus.

  Conventionally, when a particulate medicine such as powder is packaged in a wrapping paper, the medicine is supplied via a recovery hopper. In this case, when the medicine passes through the collection hopper or through the collection hopper, the medicine is charged by friction between the medicines or between the medicine and the collection hopper, and adheres to the collection hopper and cannot be properly packaged. There is. For this reason, the adhesion of the drug is prevented by various methods.

  For example, there is one that prevents the adhesion of a medicine to the recovery hopper by applying ultrasonic vibration or high voltage to the recovery hopper (see, for example, Patent Document 1).

  In addition, there is an apparatus in which a particle is neutralized by a neutralization device including a plurality of ejection nozzles that eject ions (see, for example, Patent Document 2).

In addition, there are brushes and conductive pads made of conductive fibers provided on the surface of a grounded conductive plate, and these are slidably contacted with the surface of the packaging sheet to eliminate static from the packaging sheet (for example, patents) References 3 and 4).

  However, in the invention described in Patent Document 1, since it is necessary to vibrate the entire recovery hopper or to apply a high voltage to the entire recovery hopper, the apparatus is large and expensive.

  Further, the invention described in Patent Document 2 requires a static eliminator provided with a plurality of discharge nozzles, which not only requires a wide arrangement space, but also complicates the structure and causes an increase in cost.

  Furthermore, in the inventions described in Patent Documents 3 and 4, it is only possible to neutralize the packaging sheet, and it is difficult to appropriately prevent the drug from adhering to the recovery hopper.

  Therefore, an object of the present invention is to provide a medicine packaging device that can perform appropriate packaging processing by preventing the adhesion of medicines despite the simple and inexpensive configuration.

The present invention provides a medicine packaging device as means for solving the above-mentioned problems,
A wrapping paper transport unit for transporting a strip of wrapping paper in the longitudinal direction;
A recovery hopper that has a medicine passage through which medicine passes, and is arranged so that a lower end opening of the medicine passage is positioned between wrapping papers conveyed in a state of being overlapped by the wrapping paper conveyance unit;

An electrode part that is located in the vicinity of the lower end opening of the recovery hopper with the wrapping paper sandwiched between them, and based on the applied voltage, applies a Coulomb force to the drug passing through the recovery hopper,
At least during the time when the medicine is supplied from the recovery hopper to the wrapping paper, a control unit that performs on / off control so that a voltage is applied to the electrode unit is provided.

  With this configuration, when a medicine is supplied into the wrapping paper through the recovery hopper, a Coulomb force can be applied to the medicine by applying a voltage to the electrode portion and charging it. In this case, it is preferable to increase the Coulomb force that acts on the drug compared to the recovery hopper. In addition, since ions can be generated around the electrode portion, the drug can be made nonpolar by making the ions have a polarity opposite to the charged polarity of the drug. Therefore, it becomes possible to appropriately supply the medicine into the wrapping paper without attaching it to the collection hopper. In addition, by controlling the on / off of the electrode part, it is possible to reliably prevent charging of the recovery hopper and the like accompanying application of voltage to the electrode part.

  When the lower end opening is formed in a substantially streamlined shape along the conveyance direction of the wrapping paper, the collection hopper can smoothly convey the wrapping paper and can suppress the charging of the collection hopper and the wrapping paper. It is preferable in that the supply of can be made appropriate.

The seal part seals simultaneously a position for partitioning two packages of wrapping paper conveyed by the wrapping paper conveyance unit and a side edge portion straddling the two packages,
The control unit seals the wrapping paper by the sealing unit, applies a voltage to the electrode unit, supplies the medicine into the wrapping paper through the recovery hopper, and then removes the wrapping paper by the wrapping paper transport unit. It is preferable to stop the application of voltage to the electrode part before the package transfer is completed.

  With this configuration, after the medicine is supplied into the wrapping paper, the Coulomb force acting on the medicine is removed from the electrode portion before the wrapping paper is transported to the next sealing position. It stays at the proper position and does not reach the next sealing position. Therefore, the medicine is sealed at the sealing position, and sealing failure or the like is not caused.

The collection hopper includes an opening / closing plate,
The opening / closing plate is rotatable between a closed position where the medicine can be temporarily stored and an open position where the stored medicine is discharged to the wrapping paper through the lower end opening,
The control unit stops conveyance of the wrapping paper by the wrapping paper conveyance unit, starts sealing of the wrapping paper by the seal unit, rotates the opening / closing plate to an open position, and then supplies the wrapping paper to the electrode unit. It is preferable that the application of the voltage is stopped after the application of the voltage is started and the supply of the medicine is completed and the transport of the wrapping paper is resumed.

  With this configuration, it is possible to accurately grasp the time when the medicine is supplied to the wrapping paper based on the opening / closing operation of the opening / closing plate, and it is possible to accurately apply and stop the voltage to the electrode unit.

  When the control unit can maintain the open / close plate in an open state according to the type of drug passing through the recovery hopper, it can appropriately prevent the drug (adhesive drug) that easily adheres to the hopper, such as Yokuinin, from remaining in the hopper. This is preferable in that it can be performed.

  If the control unit varies the polarity of the voltage applied to the electrode unit according to the type of drug to be packaged, it can appropriately prevent adhesion to various drugs having different charged polarities. This is preferable.

Wherein the control unit, the electric instead of stopping of the voltage applied to the electrode unit, when the polarity of the applied voltage and reverse polarity, with more, the medicine supplied to the wrapping paper can be retained in a desired position This is preferable in that charging of the recovery hopper and the like accompanying application of voltage to the electrode portion can be prevented.

  It is preferable that the recovery hopper is made of a material close to the medicine to be passed and on the charged train, in that the charging of the recovery hopper itself can be suppressed and the adhesion of the medicine can be prevented.

  The wrapping paper transport unit includes one that folds and transports a belt-shaped wrapping paper, and one that transports two strips of wrapping paper. The conveyance direction includes a horizontal direction, a diagonally downward direction, a vertically downward direction, and the like.

  As the recovery hopper, those made of various materials such as resin and metal can be used, and the shape may be any funnel-like shape that can collect the drug in one place.

  As the sealing part, the partition position and the side edge position of two adjacent packages are sealed at the same time, and in addition to the configuration in which one package is formed by two seals, the side edge part located on the upper side is left, After sealing the partition position with the both sides of one package to supply, the structure etc. which seal the said side edge part to make one package, etc. are employable.

  As said electrode part, the thing of various forms, such as linear form and plate shape, can be used. When using a linear electrode part, it is preferable to arrange | position along the lower end opening edge part of a collection | recovery hopper. In addition, if the electrode part is provided with a plurality of protrusions that protrude toward the lower end opening of the recovery hopper, it is possible to prevent the drug from being concentrated on the lower end opening where the drug easily adheres. It becomes.

A surface potential detector for detecting the surface potential of the recovery hopper ;
Wherein, based on the surface potential detected by the surface potential detection unit, preferably that determine the polarity of the voltage applied to the electrode portion.

  With this configuration, it is not necessary to store the polarity that is likely to be charged for each medicine as data, and based on the detection signal in the surface potential detection unit, the residual in the collection hopper can be appropriately maintained regardless of the kind of medicine. It becomes possible to prevent.

  It is preferable that the control unit does not apply a voltage to the electrode unit if the surface potential detected by the surface potential detection unit is within a predetermined range of positive and negative values.

  With this configuration, based on the surface potential detected by the surface potential detection unit, it is determined whether or not the potential of the charged drug is likely to change, and voltage application to the electrode unit is prohibited. This makes it possible to perform an appropriate packaging process.

  According to the present invention, there is provided an electrode portion that is located in the vicinity of the lower end opening of the recovery hopper with the wrapping paper interposed therebetween and that applies a Coulomb force to the medicine passing through the recovery hopper based on the applied voltage. Since the applied voltage is controlled to be turned on / off, it is possible to prevent the medicine from adhering to the recovery hopper and to reliably supply the medicine to an appropriate position in the wrapping paper for packaging.

  Embodiments according to the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 shows a medicine packaging apparatus according to this embodiment. This medicine packaging apparatus includes a tablet supply unit 2 and a powder supply unit 3 on the upper side of the apparatus main body 1, and a printing unit 4 and a packaging unit 5 (both in FIG. 1 by a cover 1a). It is covered.)

  The tablet supply unit 2 accommodates one tablet in advance in each box 6 formed in a lattice shape by hand and sequentially opens the bottom plate of each box 6 so that the packaging unit 5 can package the tablets. This is what you can do. The tablet supply unit 2 includes one that can be automatically supplied by a tablet feeder 33 as shown in FIG.

  The powder supply unit 3 drops the powder stored in the V basket 7 and equally divides it with a plurality of divided containers (not shown) arranged on the lower side thereof, and then a divided container feed motor 40 (see FIG. 14). In this way, the divided containers are conveyed, and the bottom plate of each divided container is opened by driving the powder push-up motor 41 (see FIG. 14) so that the packaging unit 5 can sequentially package the divided containers. When changing the type of powder to be packaged, the remaining powder is cleaned by the vacuum cleaner 29 and then supplied to the V 枡 7. The powder is charged in the process of being supplied into the wrapping paper 8, and the charged state is different depending on the type as shown in Table 1. As will be described later, this data is stored in the storage device 46 and used to control the voltage applied to the electrode unit 31.

印刷ユニット４は、図３に示すように、ロール８ａに巻回した包装紙８を巻き戻し、プリンタ４２（図１４参照）にて所定の印刷を施した後、包装ユニット５へと搬送するようにしたものである。ここでは、包装紙８にはグラシン紙を使用している。

As shown in FIG. 3, the printing unit 4 rewinds the wrapping paper 8 wound around the roll 8 a, performs predetermined printing with the printer 42 (see FIG. 14), and then transports it to the packaging unit 5. It is a thing. Here, glassine paper is used for the wrapping paper 8.

  As shown in FIGS. 4 to 6, the wrapping unit 5 is a state in which the wrapping paper 8 printed by the printing unit 4 is conveyed in the longitudinal direction by the wrapping paper conveyance unit 9 and folded in two or in advance. Thus, the medicine supplied from the tablet supply unit 2 or the powder supply unit 3 is supplied through the recovery (powder) hopper 10 and sealed by the seal unit 11 to form a bag. However, the wrapping paper 8 may be a laminate of two long sheets.

The wrapping paper transport unit 9 is composed of a pair of delivery rollers 12a and 12b. One feed roller 12a is rotationally driven by a paper feed motor 44 (stepping motor 30), and conveys the wrapping paper 8 sandwiched between the feed rollers 12a and 12b. In addition, the conveyance amount of the wrapping paper 8 is changed according to the difference in the amount of medicine per package. Here, the carry amount is determined based on the number of pulses of the stepping motor 30.

Collecting hopper 10, as shown in FIG. 7, consisting of funnel-shaped upper side collection hopper 13 and the lower side collected hopper 1 4. The upper collection hopper 13 is separated into a tablet passage 13 a and a powder passage 13 b, and a lower opening of the powder passage 13 b is opened and closed by an opening / closing plate (hopper perimeter) 15. The opening / closing plate 15 is opened / closed by the action of a powder hopper peller motor (not shown). Thereby, the supplied powder does not fall over a long distance and directly reaches the wrapping paper, and scattering at the time of dropping is prevented. Lower side collected hopper 1 4 lower opening cylindrical portion 14a is a substantially elliptical shape, preferably, a substantially streamlined shape along the conveying direction of the wrapping paper 8, the dimensions of the long axis side matches the seal width, the opening The edge is curved so as to be recessed at the center. Even with this configuration, the powdered medicine is prevented from scattering from the inside of the wrapping paper 8. The powder adhering to the inner surface of the recovery hopper 10 is forcibly dropped by driving a powder hopper vibrator (not shown). Further, powdered medicine which soared downward collection hopper 1 4 is discharged through the exhaust duct 14b. In addition, a separation guide 17 (see FIG. 3) is provided in the vicinity of the collection hopper 10, that is, on the upstream side in the conveyance direction of the wrapping paper 8, and the wrapping paper 8 that is folded in two is smoothly smoothed on both sides of the lower opening cylinder portion 14a. It is possible to be located in. A pair of clamping pieces 32 is provided in the vicinity of the upstream side in the transport direction of the wrapping paper 8 with respect to the recovery hopper 10. Clamping piece 32, by clamping the wrapping paper 8 is positioned along the bottom opening cylinder portion 14a of the lower hopper 1 4, wrapper ensures that contact with the electrode portion (the ion generation portion) 31 to be described later To avoid.

  The seal portion 11 is provided with a first seal block 19 and a second seal block 20 on the side plate 18 of the apparatus body 1 so as to be openable and closable, and is attached in an inclined state corresponding to the wrapping paper 8 that is inclined downward. ing. Both seal blocks have a seal surface that is contacted and separated by driving the main pack motor 43, the paper feed motor 44, etc., and a position orthogonal to the folding line of the folded wrapping paper 8 (adjacent two-packet partition position). , And sealed in a substantially T-shape at a position opposite to the fold line (side edge position straddling two adjacent packages).

The electrode portion 31 is made of a wire made of a conductive material, and is attached to a fixed base 21 fixed to the seal portion 11 so as to be positioned in the vicinity of the lower end opening cylinder portion 14a. The fixed base 21 includes a substantially U-shaped escape portion through which the wrapping paper 8 can pass, and a part thereof extends upward. The electrode part 31 is attached along the inner edge of the fixed base 21, and a voltage is applied to one end part from a power supply unit (not shown). Electrode portion 31, the is disposed along the opening edge of the lower collecting hopper 1 4 of the lower end opening tube portion 14a, located on the outer surface near the wrapping paper 8 is conveyed along the outer circumferential surface of the lower end opening tube portion 14a is doing. Thus, the electrode unit 31 is the most powdered medicine adheres easily portion of the lower collecting hopper 1 4, so that the action of effectively Coulomb force to the powdered medicine. The shape of the electrode portion 31 is not limited to the linear shape described above, but may be a needle shape or a plate shape, and may be provided not only on one side of the wrapping paper 8 but also on both sides. The point is that the Coulomb force can be effectively applied to the powder.

  When the wrapping paper 8 passes through the wrapping unit 5, a cut is formed in the seal portion 11 by the cutter 22.

  An upper operation panel 23 shown in FIG. 8 is provided on the upper surface of the apparatus main body 1, and a front operation panel 24 shown in FIG. 9 is provided on the front surface. Based on the input signals from these operation panels 23 and 24, as shown in FIG. In addition to the divided container feed motor 40, push-up motor 41, printer 42, pack motor 43, and paper feed motor 44, a storage device 46 is connected to the control device 45, and another computer is connected via the transmission / reception unit 47. 48 (including a host computer) is connected to the network.

  Next, the operation of the medicine packaging apparatus will be described according to the flowcharts of FIGS. 10 and 11 with reference to the timing charts of FIGS.

  The control device 45 determines whether there is prescription data transmitted or input (step S1), and if there is, reads the prescription data (step S2).

Then, based on the read prescription data, it is determined whether or not the supplied medicine is an attached medicine (step S3). That is, powders that contain a large amount of water and are likely to adhere to the hopper are registered in advance as a database, and it is determined whether or not the supplied drug corresponds to the powder. Here, Senna powder, Yokuinin, tannabin (registered trademark) (especially Yokuinin is easily attached), and the like are registered as adhesion drugs. Here, it is determined whether or not it is an adhering drug automatically based on the database, but when an operation button (indicated by reference numeral 34 in FIG. 8) is operated separately (here, When the pressing operation is performed for 1 second or more), it may be determined that the medicine is an adhesive. In this case, it is preferable to turn on the LED 35 to display the fact.

  In the case of an adhering drug, as shown in FIG. 13, the opening / closing plate 15 in the recovery hopper 10 is maintained in an open state (step S16), and the powder push-up motor 41 is driven to open the bottom plate of the divided container. Is supplied (step S17), and the seal portion 11 is operated by driving the main pack motor 43 to start sealing (step S18). Since the opening / closing plate 15 is maintained in an open state, the adhering drug falls directly onto the wrapping paper 8 and is prevented from remaining in the collection hopper 10. Moreover, the seal | sticker by the seal | sticker part 11 is complete | finished before a powdered medicine reaches the wrapping paper 8 by open | releasing the baseplate of a division | segmentation container (step S19, S20). And if a chemical | medical agent is supplied to the wrapping paper 8, a powder hopper vibrator will be driven and the adhesion medicine which remains in the collection | recovery hopper 10 will be forcibly dropped. Thereafter, the conveyance of the wrapping paper 8 is resumed (step S21), and stopped when one package is conveyed (step S22). The start and end of the seal and the resumption of the conveyance of the wrapping paper 8 are all controlled based on the elapsed time from the opening of the bottom plate of the divided container.

  On the other hand, if it is other than the adhering drug, as shown in FIG. 12, the open / close plate 15 is closed (step S4), the bottom plate of the divided container is opened to supply the drug (step S5), and the drug is once recovered. Store in the hopper 10. Thereby, for example, when the medicine to be supplied is powder, it is prevented that the medicine is directly supplied into the wrapping paper 8 and scattered. Further, the sealing of the wrapping paper 8 by the seal portion 11 is started (step S6).

  Then, the opening / closing plate 15 is opened (step S7), and the medicine stored in the collection hopper 10 is dropped onto the wrapping paper 8. Further, it is determined whether or not the medicine to be supplied is powder (step S8).

  When it is determined that the medicine to be supplied is powder, after waiting for a predetermined time (step S9), energization to the electrode unit 31 is started (step S10) and the sealing of the wrapping paper 8 is ended (step S11). Energization of the electrode unit 31 is performed in order to forcibly attract the electrode unit 31 because powder powder is charged due to friction at the time of supply or the like and may adhere to the recovery hopper 10 due to Coulomb force. In this case, the powder to be packaged is charged with a polarity opposite to the polarity of the powder, as shown in Table 1 above, depending on the type. In particular, in the case of aspirin, since the voltage value at the time of charging is large, by applying a high voltage of 7 kV to the electrode part 31, the powder that passes through the collection hopper 10 is made to act on the drug compared to the collection hopper 10. Increase the coulomb force. As a result, the powder falling in the collection hopper 10 is supplied into the wrapping paper 8 without adhering to the collection hopper 10. In addition, application of a voltage to the electrode unit 31 acts to ionize the ambient atmosphere and neutralize the charge of the powder. Therefore, the powder is relaxed in the charged state and is sucked into the electrode portion 31 by the Coulomb force stronger than that of the recovery hopper 10 and moves into the wrapping paper 8.

  The waiting time in step S9 is a time before the medicine reaches the wrapping paper 8 by opening the opening / closing plate 15, and is a time during which the wrapping paper 8 can be properly sealed.

  Subsequently, after waiting for a predetermined time when it is determined that the medicine has been completely supplied into the wrapping paper 8 (step S12), the wrapping paper 8 that has been subjected to the predetermined printing by the wrapping unit 5 is transferred to the wrapping paper transport unit 9. Is transported by one package (step S13). Further, energization of the electrode unit 31 is stopped during the conveyance of the wrapping paper 8 (step S14). Thereby, a powdered medicine stays in the position which stopped the electricity supply to the electrode part 31, and the further movement is blocked | prevented. Therefore, powdered medicine does not reach the next sealing position, and a sealing failure between two adjacent packets is prevented.

  Thereafter, the conveyance of the wrapping paper 8 is stopped (step S15), and it is determined whether there is a next packaging (step S16). If there is a next package, the process returns to step S3 and the same operation is repeated. When there is no next packaging, sealing by the seal part 11 is performed (step S17), the packaging process based on the said prescription data is completed, and it returns to step S1 and it is judged whether there exists other prescription data. If there is no other prescription data, the packaging process is terminated.

  In the embodiment, the storage device 46 stores data indicating the charged state according to the type of drug as shown in Table 1, and applies a positive or negative voltage to the electrode unit 31 based on the data. However, as shown by a two-dot chain line in FIG. 14, if the hopper charging sensor 49 is provided, such data is not necessary.

  That is, when the drug passes through the collection hopper 10 and is charged to any polarity, the surface potential of the collection hopper is opposite to the charged drug due to the influence. Therefore, based on the surface potential of the recovery hopper 10 detected by the hopper charging sensor 49, a voltage having the same polarity as this detection potential is applied to the electrode portion 31, thereby applying a Coulomb force to attract the drug. Can be made.

  At this time, it is preferable to determine the applied voltage to the electrode unit 31 so that the Coulomb force acting on the medicine is larger than the Coulomb force acting on the medicine by the charged recovery hopper 10.

  If the detected surface potential is within a predetermined range near zero, it is preferable to prohibit the application of voltage to the electrode unit 31. That is, depending on the medicine, there is a medicine that can be charged either positively or negatively in the process of being supplied through the recovery hopper 10. When the potential is reversed in the supply process, simply applying a voltage to the electrode unit 31 based on the detected potential may cause a repulsion to the Coulomb force acting on the drug. Therefore, in such a case, application of voltage to the electrode unit 31 is prohibited by prohibiting application of voltage to the electrode unit 31.

  Moreover, in the said embodiment, although the structure which made the 1st seal block 19 and the 2nd seal block 20 contactable / separable was employ | adopted as the seal part 11 of the packaging unit 5, conventionally well-known roller-type as shown in FIG. It is also possible to employ the seal portion 50 (see, for example, JP-A-9-202301).

  The seal portion 50 includes a vertical seal portion 51 and a horizontal seal portion 52. The vertical seal 51 includes a horizontal heating surface 51a formed in a fan shape and a feed surface 51b formed in a straight line. Each of the seal portions 51 and 52 is adapted to transmit the driving force of the heater roller motors 53 and 54 via gears.

  In the seal portion 50, the electrode portion 31 is disposed in the vicinity of the upstream side of the seal portion. And drive control of a motor etc. is performed as follows.

  That is, it is the same as the above-mentioned packaging unit 5 that the normal powder and the adhering drug are processed separately. However, the drive timing of the motor or the like is different.

  In the case of an adhering drug, as shown in the timing chart of FIG. 16, the open / close plate 15 in the collection hopper 10 is maintained in the open state, the powder divided container feed motor 40 is driven, and the powder push-up motor 41 is driven as described above. Then, the medicine is supplied by opening the bottom plate of the divided container. The heater roller motors 53 and 54 are temporarily stopped immediately before the powder push-up motor 41 starts to be driven. Then, driving is started in accordance with the powder push-up motor 41. At this time, the wrapping paper 8 is conveyed by driving the heater roller motors 53 and 54. Further, the collection hopper 10 is vibrated by driving a vibrator (not shown) with a delay from the start of supply of the medicine and the start of conveyance of the wrapping paper 8. Simultaneously with this vibration, a voltage is applied to the electrode portion 31 to suck the drug toward the wrapping paper 8 side. Then, before the next feed surface 51b of the vertical seal portion 51 vertically seals the wrapping paper 8, the powder push-up motor 41 is stopped to stop the supply of the medicine from the divided container. Thereby, the medicine is supplied to the wrapping paper 8 while the collection hopper 10 is vibrating and is sucked by the electrode unit 31. Therefore, the medicine does not remain in the collection hopper 10. Further, immediately before the next feeding surface 51b of the vertical seal portion 51 vertically seals the wrapping paper 8, the driving of the vibrator and the application of the voltage to the electrode portion 31 are stopped. Thereby, it is possible to prevent a problem that the medicine is supplied to the vertical seal portion and sealed.

  On the other hand, when it is a non-adhesive drug, that is, a normal powder, the drive timing of each motor or the like is determined as shown in the timing chart of FIG. The timing of driving the powder divided container feed motor 40, the powder push-up motor 41, and the heater roller motors 53 and 54 is the same as in the case of the adhering drug. Then, it is delayed from the time when it is determined that the medicine dropped from the divided container by driving the powder push-up motor 41 is accommodated in the collection hopper 10 (for opening and closing the opening / closing plate 15 of the collection hopper 10). Start driving the hopper-pereller motor. At the same time, the driving of the vibrator is started, and a voltage having a polarity opposite to that of the drug is applied to the electrode unit 31.
