The present invention relates to a pharmaceutical packaging device.

Conventionally, in the case of packing a granular drug such as powdered medicine in a wrapping paper, the drug is supplied through a recovery hopper. In this case, when the medicine passes through the conveyance path to the recovery hopper or the recovery hopper, the medicines are charged by friction between the medicines or the medicine and the recovery hopper and adhere to the recovery hopper. have. For this reason, the adhesion of a medicament is prevented by various methods.

For example, the ultrasonic pulverization or a high voltage is applied to the recovery hopper to prevent adhesion of a drug to the recovery hopper (see Patent Document 1, for example).

In addition, there is a case in which the fine powder is discharged by an antistatic device having a plurality of discharge nozzles for releasing ions (see Patent Document 2, for example).

In addition, a brush or conductive pad made of conductive fibers is provided on the surface of the grounded conductive plate, and some of them are subjected to static contact from the packaging sheet by sliding contact with the surface of the packaging sheet (see, for example, Patent Documents 3 and 4). ).

<Patent Document 1> Japanese Patent Laid-Open No. 6-183483

<Patent Document 2> Japanese Patent Application Laid-Open No. 2002-59904

<Patent Document 3> Japanese Patent Utility Model Registration No. 2557369

<Patent Document 4> Japanese Patent Utility Model Registration No. 2557370

However, in the invention described in Patent Document 1, since the entire recovery hopper needs to be vibrated or a high voltage is applied to the entire recovery hopper, the apparatus is large scale and expensive.

In addition, in the invention described in Patent Document 2, an antistatic device having a plurality of discharge nozzles is required, a large arrangement space is required, the structure is complicated, and the cost is increased.

In addition, in the inventions described in Patent Literatures 3 and 4, only the static elimination of the packaging sheet is possible, and it is difficult to properly prevent the adhesion of the drug to the recovery hopper.

As shown in FIG. 3, the printing unit 4 rewinds the wrapping paper 8 wound on the roll 8a and performs predetermined printing by the printer 42 (see FIG. 14). ) To return. Here, glassine paper is used for the wrapping paper 8.

The packaging unit 5 conveys the wrapping paper 8 printed by the said printing unit 4 in the longitudinal direction by the wrapping paper conveying part 9, as shown in FIG. 4 thru | or 6, Alternatively, the medicine supplied from the tablet supply section 2 or the powdered medicine supply section 3 is supplied through the recovery (powder medicine) hopper 10 in a state of folding twice in advance, and is sealed by the seal section 11. To form a pocket. However, the wrapping paper 8 may stick two long sheets.

The said wrapping paper conveyance part 9 is comprised by a pair of sending roller 12a, 12b. One feeding roller 12a is rotationally driven by the sheet feeding motor 44 (stepping motor) 30 to convey the wrapping paper 8 held by the two feeding rollers 12a and 12b. In addition, the conveyance amount of the wrapping paper 8 is changed according to the difference of the chemical | medical agent quantity per 1 bag. Here, the conveyance amount is determined based on the number of pulses of the stepping motor 30.

As shown in FIG. 7, the recovery hopper 10 includes a funnel-shaped upper side recovery hopper 13 and a lower side recovery hopper 10. The upper side recovery hopper 13 is separated into a purification passage 13a and a powdered medicine passage 13b, and the lower opening of the powdered medicine passage 13b is opened and closed by an opening / closing plate (hopper hopper) 15. The opening and closing plate 15 is opened and closed by the action of a powdered medicine hopper Ferrara motor (not shown). Thereby, the powdered medicine supplied does not fall a long distance and directly reach a wrapping paper, and scattering at the time of a fall is prevented. The lower opening cylindrical portion 14a of the lower side recovery hopper 10 has an approximately elliptical shape in cross section, preferably a substantially streamline shape along the conveying direction of the wrapping paper 8, and the dimension on the long axis side is determined by the seal width. Matching, the opening edge is curved as if it is recessed in the center. This configuration also prevents the powdered medicine from flying around from the wrapping paper 8. In addition, the powdered medicine adhering to the inner surface of the recovery hopper 10 is forcibly dropped by driving the powdered medicine hopper vibrator (not shown). In addition, the powdered medicine flying in the lower side recovery hopper 10 is discharged through the exhaust duct 14b. In addition, the separation guide 17 (refer FIG. 3) is provided in the vicinity of the collection | recovery hopper 10, ie, the conveyance direction upstream of the wrapping paper 8, and the 2nd folding wrapping paper 8 smoothly opens the lower opening cylinder part. It is possible to locate at both sides of 14a. Moreover, the pair of clamping pieces 32 are provided in the vicinity of the conveyance direction upstream of the wrapping paper 8 with respect to the collection | recovery hopper 10. The clamping piece 32 clamps the wrapping paper 8 and positions it so that it may follow the lower opening cylinder part 14a of the hopper 10, and it makes contact with the electrode part (ion generating part) 31 mentioned later. Definitely avoid

The seal part 11 is provided with the first seal block 19 and the second seal block 20 on the side plate 18 of the apparatus main body 1 so as to be openable and close, and the wrapping paper 8 facing downward. It is mounted in an inclined state in response to this. The two seal blocks are brought into contact with and separated from each other by the drive of the main pack motor 43, the paper feed motor 44, and the like, and are orthogonal to the bending line of the wrapping paper 8 in two-fold folding. It seals in a substantially T-shape at the division position of two bags and the position (side edge position over two adjacent bags) opposite to a bending line.

The said electrode part 31 is comprised from the wire rod which consists of electroconductive materials, and is attached to the fixing stand 21 fixed to the said seal part 11 so that it may be located in the vicinity of the lower end opening 14a. The fixing stand 21 is provided with the substantially U-shaped discharge part which the wrapping paper 8 can pass through, and the one part is extended and installed upward. The electrode part 31 is attached along the inner edge of the fixing base 21, and a voltage is applied to one end from a power supply unit not shown. The electrode portion 31 is disposed along the opening edge of the lower opening cylindrical portion 14a of the recovery hopper 10 and is located near the outer surface of the wrapping paper 8 conveyed along the outer circumferential surface of the lower opening cylindrical portion 14a. have. As a result, the electrode portion 31 effectively exerts a coulomb force on the powdered medicine at the portion where the powdered medicine of the recovery hopper 10 is most easily attached. In addition, the shape of the said electrode part 31 is not limited to the linear thing mentioned above, It may be needle shape or plate shape, and may be provided not only on the one side of the wrapping paper 8, but on both sides. Urinary need only be able to apply the Coulomb force to the powdered medicine effectively.

In addition, when the wrapping paper 8 passes through the wrapping unit 5, a gap is formed in the seal portion 11 by the cutter 22.

The upper operation panel 23 shown in FIG. 8 is provided in the surface of the said apparatus main body 1, and the front part operation panel 24 shown in FIG. 9 is provided in the front surface, respectively. Based on the input signals from these operation panels 23 and 24, each part is controlled by the control apparatus 45 as shown in FIG. The storage device 46 is connected to the control device 45 in addition to the division container transfer motor 40, the pressurization motor 41, the printer 42, the pack motor 43, and the paper feed motor 44. The network is connected to another computer 48 (including a host computer or the like) via the transmission / reception unit 47.

Next, the operation | movement of the said chemical | medical agent packaging apparatus is demonstrated, referring the timing chart of FIG. 12 and FIG. 13 according to the flowchart of FIG. 10 and FIG.

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

Then, based on the read prescription data, it is judged whether or not the supplied medicine is an adhesive drug (step S3). That is, the powdered medicine which has much water content and is judged to be easy to adhere to a hopper is previously registered as a database, and it is judged whether the supplied medicine corresponds to the powdered medicine. Here, the senna powder, the yokinin, a tunnel bean (especially the yokinin is easy to adhere), etc. are registered as an adhesion agent. In this case, it is determined whether or not the drug is automatically applied based on the database. However, if the operation button (indicated by reference numeral 34 in FIG. 8) is operated separately (in this case, the pressure operation is performed for 1 second or more), the attachment is performed. You may judge by medicine. In this case, it is preferable to turn on the LED 35 and display the effect.

In the case of the adhesive agent, as shown in FIG. 13, the open / close board 15 in the collection | recovery hopper 10 is kept open (step S16), and the powdered medicine pressurization motor 41 is driven to open the bottom plate of a division container. The chemical | medical agent is supplied (step S17), the seal part 11 is operated by the drive of the main pack motor 43, and a seal | sticker is started (step S18). Since the opening / closing plate 15 is kept in the open state, the adherent medicine falls directly into the wrapping paper 8, and the residue in the recovery hopper 10 is prevented. In addition, the seal by the seal part 11 is terminated before the powdered medicine reaches the wrapping paper 8 by opening the bottom plate of the divided container (steps S19 and S20). Then, when the medicine is supplied to the wrapping paper 8, the powdered medicine hopper vibrator is driven to forcibly drop the adherent medicine remaining in the recovery hopper 10. Then, conveyance of the wrapping paper 8 is restarted (step S21), and it stops after conveying one package (step S22). In addition, the start of the seal, the end, and the resumption of conveyance of the wrapping paper 8 are all controlled based on the elapsed time from the bottom plate opening of the divided container.

On the other hand, when it is other than an adhesive agent, as shown in FIG. 12, the opening-closing board 15 is closed (step S4), the bottom plate of a division container is opened, and a chemical | medical agent is supplied (step S5), and once, a chemical | medical agent Is stored in the recovery hopper 10. Thereby, for example, when the chemical | medical agent to supply is a powdered medicine, it is directly supplied in the packaging paper 8, and scattering is prevented. Moreover, the sealing of the wrapping paper 8 by the sealing part 11 is started (step S6).

Then, the open / close board 15 is opened (step S7), and the medicine stored in the recovery hopper 10 is dropped onto the wrapping paper 8. In addition, it is determined whether the medicine to be supplied is a powdered medicine (step S8).

When it determines with the chemical | medical agent to supply being a powdered medicine, after waiting for predetermined time (step S9), electricity supply to the electrode part 31 is started (step S10), and sealing of the wrapping paper 8 is complete | finished (step S11). The energization of the electrode part 31 is performed in order to be able to forcibly attract the electrode part 31 because the powdered medicine is charged by friction at the time of supply, and may be attached to the recovery hopper 10 by the coulomb force. . In this case, the powdered medicine to be packaged is charged with different polarities, as shown in Table 1 above, so that the electrode portion 31 is charged with a polarity opposite to that of the powdered medicine. In particular, in the case of aspirin, since the voltage value at the time of charging is large, the coulomb which acts on a chemical | medical agent compared with the recovery hopper 10 with respect to the powdered medicine which passes inside the recovery hopper 10 by applying high voltage of 7 kV to the electrode part 31 is carried out. Increase your power. As a result, the powdered medicine falling in the recovery hopper 10 is supplied into the wrapping paper 8 without being attached to the recovery hopper 10. Moreover, it acts to ionize in an ambient atmosphere by the application of the voltage to the electrode part 31, and to neutralize the charging of powdered medicine. Therefore, the powdered medicine is alleviated in the charged state, and is attracted to the electrode portion 31 by the coulomb force stronger than that of the recovery hopper 10 to move into the wrapping paper 8.

In addition, the waiting time in the said step S9 is time before a chemical | medical agent reaches the wrapping paper 8 by opening of the opening / closing board 15, and is a time which can seal the wrapping paper 8 suitably.

Subsequently, after waiting only for the predetermined time judged that the chemical | medical agent was fully supplied in the wrapping paper 8 (step S12), the packaging paper conveying part 9 drives the wrapping paper 8 by which the predetermined | prescribed printing was performed by the packaging unit 5. Only one packet is conveyed by this (step S13). Moreover, the electricity supply to the electrode part 31 is stopped in the middle of conveyance of the wrapping paper 8 (step S14). As a result, the powdered medicine remains at the position where the energization of the electrode portion 31 is stopped, and further movement is prevented. Therefore, the powdered medicine does not reach the next seal position, and the seal failure between two adjacent bags is prevented.

Thereafter, the conveyance of the wrapping paper 8 is stopped (step S15), and it is determined whether there is the next wrapping (step S16). If there is the next package, the process returns to the step S3 and the same operation is repeated. If there is no following packaging, the 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 determines whether there exists other prescription data. If there is no other prescription data, the packaging process is terminated.

In the above embodiment, the memory device 46 stores the data indicating the charging state according to the type of the chemicals shown in Table 1 above, and applies positive or negative voltage to the electrode portion 31 based on the data. However, as indicated by the dashed-dotted line in FIG. 14, when the hopper charging sensor 49 is provided, such data is not necessary.

In other words, if the medicine is charged with some polarity when passing through the recovery hopper 10, the surface potential of the recovery hopper becomes the opposite polarity 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 coulombic force is applied to attract the drug by applying a voltage equal to this detection potential to the electrode portion 31. You can.

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

Moreover, it is preferable to prohibit application of the voltage to the electrode part 31 as long as the detected surface potential exists in the predetermined range of zero vicinity. That is, depending on the medicine, the potential to be charged may be either positive or negative in the process of being supplied through the recovery hopper 10. When the potential is reversed in the supplying process, simply applying a voltage to the electrode portion 31 based on the detected potential may cause a repulsion to the Coulomb force acting on the drug. In this case, therefore, the application of the voltage to the electrode portion 31 is prevented from being adversely affected by the application of the voltage to the electrode portion 31.

Moreover, in the said embodiment, although the structure which made the 1st seal block 19 and the 2nd seal block 20 contactable and detachable was employ | adopted as the seal part 11 of the packaging unit 5, it is shown in FIG. Conventionally well-known roller type seal 50 can also be employed (see, for example, Japanese Patent Laid-Open No. 9-202301).

The said seal part 50 is comprised from the vertical seal part 51 and the horizontal seal part 52. As shown in FIG. The vertical seal part 51 is provided with the horizontal heating surface 51a linearly formed, and the conveyance surface 51b formed linearly. In addition, the driving force of the heater roller motors 53 and 54 is transmitted to each seal part 51 and 52 via a gear.

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

That is, the process of dividing the powdered medicine and the adherent medicine normally is the same as that of the packaging unit 5 mentioned above. However, the drive timing of a motor etc. differs.

In the case of the adhesive agent, as shown in the timing chart of FIG. 16, the opening and closing plate 15 in the recovery hopper 10 is kept in the open state as described above, the powdered medicine dividing vessel transport motor 40 is driven, and the powdered medicine pressure is applied. The medicine is supplied by driving the motor 41 to open the bottom plate of the dividing vessel. The heater roller motors 53 and 54 are once stopped just before starting to drive the powdered medicine pressurization motor 41. Then, driving is started in accordance with the powdered medicine pressurizing motor 41. At this time, the wrapping paper 8 is conveyed by the drive of the heater roller motors 53 and 54. Moreover, it delays from the start of supply of a chemical | medical agent, and the start of conveyance of the wrapping paper 8, and makes the collection | recovery hopper 10 vibrate by the drive of the vibrator which is not shown in figure. Simultaneously with this vibration, a voltage is applied to the electrode part 31, and the chemical | medical agent is attracted to the wrapping paper 8 side. And before the next conveying surface 51b of the longitudinal seal part 51 longitudinally seals the wrapping paper 8, the powdered medicine pressure motor 41 is stopped and supply of the chemical | medical agent from a division container is stopped. Thereby, the chemical | medical agent is supplied to the wrapping paper 8 while the collection | recovery hopper 10 is vibrating and the suction by the electrode part 31 is carried out. Therefore, the drug does not remain in the recovery hopper 10. Moreover, just before the conveyance surface 51b of the longitudinal seal part 51 longitudinally seals the wrapping paper 8, the drive of a vibrator and application of the voltage to the electrode part 31 are stopped. Thereby, the problem that a chemical | medical agent is supplied and sealed by the longitudinal seal part can be prevented.

On the other hand, when it is other than an adhesion agent, ie, normally powdered medicine, as shown in the timing chart of FIG. 17, the drive timing of each motor etc. is determined. The driving timings of the powdered medicine dividing vessel transport motor 40, the powdered medicine pressurizing motor 41, and the heater roller motors 53, 54 are the same as in the case of the adherent drug. And the chemical | medical agent which drove the powdered medicine pressurization motor 41 and dropped from the dividing container was delayed from the time when it judged that all the chemical | medical agents were accommodated in the recovery hopper 10 (for opening and closing the opening / closing board 15 of the recovery hopper 10). The hopper starts the drive of the motor. At the same time, driving of the vibrator is started, and a chemical and a reverse polarity voltage are applied to the electrode portion 31.

According to the present invention, an electrode portion is provided near the lower end opening of the recovery hopper with the wrapping paper interposed therebetween and exerts a coulombic force on the medicine passing through the recovery hopper based on the applied voltage. Since the off control is made, the adhesion of the medicine to the recovery hopper can be prevented, and the medicine can be supplied and packaged at a proper position in the wrapping paper.
