A medicine packaging device for packaging powder has a hopper, but the opportunity for the hopper and the medicine to contact each other is extremely short compared to a coffee bagging device. That is, as described above, in the medicine packaging device, the divided medicine is put into the hopper and sent to the subsequent packaging portion, but the role of the hopper is merely a shooter and the time for the medicine to stay in the hopper. Is extremely short. Further, in the medicine packaging device, the hopper is merely a shooter and is not stirred in the hopper and does not come into contact with the auger shaft. Therefore, there is relatively little phenomenon that the drug is charged by contact with the hopper.
However, since the medicine packaging apparatus described above wraps medicine one by one, the amount of medicine filled in each bag is small. Therefore, the medicine packaging apparatus has a relatively large conveyance amount of the packaging sheet, and there are many opportunities for contact between the packaging sheet and the hopper. Therefore, the medicine packaging apparatus has a problem that the hopper is charged and proper packaging may not be performed.

And in the chemical | medical agent packaging apparatus of this invention, an ion generating part exists in the half bag-like part of the bowl- shaped packaging sheet. Therefore generated ions enters the semi bag-like portion of the sheet gutter-shaped packing, can be directly irradiated with ions against hopper, the static electricity charged to the hopper by friction with the packing sheet Neutralize.
The position of the ion generating unit is preferably upstream in the moving direction of the packaging sheet, but may be downstream.
In the present invention, it can be said that the packaging sheet functions as an ion conduction path and carries ions to the hopper.

  In the present specification, “hopper” is a general term for devices capable of dropping a medicine on a half-sack-like portion made of a packaging sheet, and has a funnel-like shape in the same manner as conventionally known ones. Any shape or form can be used as long as it can drop the drug, such as a tube or a tube.

  The reference invention has a sheet conveying means for moving the packaging sheet and a hopper for dropping the medicine, and drops the medicine from the hopper into a half-bag-like portion made of the packaging sheet, and then the packaging sheet In a medicine packaging device that finishes the bag into a complete bag, the hopper is placed between the half-sack-shaped packaging sheets and comes into contact with the hopper. The device has an ion generation unit, and is provided with an ion conduction path that guides ions generated in the ion generation unit into a half-sack-like portion of the packaging sheet.

  Since the medicine packaging apparatus of the reference invention has an ion conduction path, the ions generated in the ion generating part can be efficiently guided into the half-sack-like part of the packaging sheet and irradiated to the hopper. Therefore, in the medicine packaging device of the present invention, static electricity charged in the hopper can be neutralized smoothly.

  In the reference invention, the shape and material of the ion conduction path are not particularly limited, but for example, a tube made of resin, a bowl shape, or a guide wall shape is recommended.

  The invention according to claim 2 is characterized in that the ion generating part is provided in the vicinity of the hopper and upstream in the moving direction of the packing sheet. Device.

The medicine packaging apparatus of the present invention has a sheet conveying means for moving the packaging sheet, and the packaging sheet is continuously fed. Therefore, an air flow along the conveying direction of the packaging sheet is generated in the vicinity of the packaging sheet.
On the other hand, in the present invention, the ion generating part is provided in the vicinity of the hopper and upstream in the moving direction of the packaging sheet. Therefore, the ions move along the movement of the packaging sheet, reach the hopper, and neutralize static electricity charged in the hopper. Therefore, in the medicine packaging device of the present invention, even if the packaging sheet and the hopper are rubbed, the occurrence of problems such as the medicine sticking to the hopper or the medicine falling to an unexpected place is prevented. it can.

Here, the present invention comprises an ion generator for generating ions, the ion generating device has an ion generating unit, the ion generating device Ru configuration der capable of irradiating directly ions into the hopper.

In the invention disclosed in Patent Document 2 described above, since ions are supplied from the outside of the sheet, the amount of ions reaching the main charged portion is small. On the other hand , since it is a structure as mentioned above , since it can irradiate ion directly with respect to a hopper, it can prevent charging more efficiently.

  In the above-described invention, the ion generating part is an electrode.

  Since the ion generator is an electrode, the shape is small. Therefore, the overall shape of the medicine packaging device can be reduced in size.

  The invention according to claim 3 has an electrode holding member for holding the electrode, the electrode holding member is in the half-sack-like portion of the packaging sheet, and the electrode is held on the side surface of the electrode holding member. It is a medicine packaging device according to claim 1 or 2 characterized by things.

The drug packaging device of the present invention has an electrode holding member that holds an electrode. The electrode is held on the side surface of the electrode holding member.
In the present invention, the electrode holding member is in the half bag-shaped portion of the packaging sheet. However, since the electrode is held on the side surface of the electrode holding member as described above, the electrode holding member becomes the packaging sheet. Even if it touches, it can prevent that an electrode touches the packaging sheet. Therefore, in the medicine packaging device of the present invention, it is possible to prevent the packaging sheet from being damaged by the electrodes.

  The invention according to claim 4 has a guide member for holding the electrode, and the wrapping sheet is formed by stacking a plurality of sheets in advance and adhering one side thereof, or bending one sheet to form the bottom. And the electrode is held on the side surface of the guide member, and the guide member is provided with an open portion on the other side excluding the bonded portion or the bent portion of the sheet.

Therefore, in the present invention, the electrode holding member also serves as a sheet lifting prevention function.
That is, in the medicine packaging device, the amount of medicine filled in each bag varies. Depending on the device, a solid medicine such as a tablet may be packaged at the same time. Therefore, sometimes a considerably large amount of medicine is filled in the bag.
However, when a large amount of medicine is filled in the bag, the bag may swell and the bottom of the bag may be pulled and moved upward.
Therefore, in the present invention, a part of the electrode holding member can be brought into contact with the bottom of the packaging sheet in the form of a half bag to suppress the rise of the bottom.

  In the present invention, the electrode is attached to the side surface of the guide member. Therefore, even if the bottom of the packaging sheet is pressed by the tip of the guide member as described above, the electrodes can be prevented from touching the packaging sheet. Therefore, also in the medicine packaging apparatus of the present invention, it is possible to prevent the packaging sheet from being damaged by the electrodes.

  In the invention according to claim 5, the hopper has a drug drop portion, the drug drop portion is provided with an opening and a friction portion, and the ion generator constitutes a material and a hopper constituting a packaging sheet. The medicine packaging according to any one of claims 1 to 4, characterized in that it generates more charged ions that the friction part of the hopper will be charged on the basis of the charged train of the material to be charged. Device.

As described above, the present invention has a sheet conveying means for moving the packaging sheet, and prevents charging due to contact between the packaging sheet and the hopper. Therefore, the present inventors initially set the hopper with ions having a charge opposite to the charge that would be charged by the hopper based on the material constituting the packaging sheet and the charge train of the material constituting the hopper. To neutralize the hopper's charge.
However, this experiment was unsuccessful and a larger amount of drug had adhered to the hopper.
The pursuit of this cause was as follows. That is, since the packaging sheet is always running and is always in contact with the side part (side surface part) of the hopper, the side part of the hopper constitutes the material and the hopper constituting the packaging sheet. The hopper is charged to the charge that will be charged based on the charge train of the material.
However, the protruding end portion of the hopper is not in contact with the packaging sheet. Therefore, most of the hopper is charged to the charge that the hopper will be charged based on the material constituting the packaging sheet and the charge train of the material constituting the hopper, but only the tip part has the opposite charge. Is charged.
Therefore, when the hopper is irradiated with ions having a charge opposite in polarity to the charge that the hopper would be charged, an unexpected result that the adhesion amount of the drug increases was caused.
Therefore, the present invention has been completed based on this knowledge, and the ion generator is configured to charge the hopper to be charged based on the material constituting the packaging sheet and the charge train of the material constituting the hopper. It was decided to generate more charged ions. As a result, the charge at the tip of the hopper was neutralized and the adhesion of the drug was eliminated.

  The invention according to claim 6 includes a powder hopper for dropping powder, a solid drug hopper for dropping solid drug, and a collecting hopper that covers the outside of both, and the powder and solid drug for dropping powder hopper The solid medicine that falls on the hopper is collected together in the collecting hopper, and the medicine is introduced into the bag made of the packaging sheet through the collecting hopper, and a suction device is connected to the collecting hopper, The medicine packaging device according to any one of claims 1 to 5, wherein a lid member that can be opened and closed is provided on a charging side of the medicine hopper.

The drug packaging device of the present invention has a function of more completely preventing drug mixing.
That is, since the medicine packaging device is for packaging medicines one by one according to the prescriptions of individual viewers, the medicines passing through the hopper are different every time. Therefore, it is desirable that the medicine packaging device has a configuration that can maintain the inside of the hopper in a clean state.
Based on this knowledge, in the medicine packaging device of the present invention, a suction device is connected to the collecting hopper, and the inside of the hopper can be cleaned.
In the present invention, a lid member that can be opened and closed is provided on the charging side of the solid drug hopper. Therefore, in this invention, cleaning of the powder hopper can be performed more completely. In other words, when a powder hopper and a solid drug hopper are provided and both powder and solid drug can be handled, powder is generally hopper (powder hopper) rather than solid drug. There is a high probability that it will need to be cleaned. However, in the prior art, the charging side of the solid drug hopper is always open, and there is no known one having a function of closing it. Therefore, if a suction device is connected to the collecting hopper and the inside of the collecting hopper is sucked, a large amount of air is inhaled from the charging side of the solid drug hopper, and the amount of air passing through the essential powder hopper is reduced. There was a problem. Therefore, in the present invention, a lid member that can be opened and closed is provided on the charging side of the solid drug hopper, and the charging side of the solid drug hopper is closed as necessary to prevent a decrease in the amount of air passing through the powder hopper.

A position that is shifted upward from the opening (hereinafter referred to as a friction portion 28b if necessary) is rubbed with the wrapping paper 15 and charged.

  Here, as described above, the drug dispensing portion 28 is made of polystyrene resin. The wrapping paper 15 is formed of glassine paper whose surface is coated with polyethylene resin. Therefore, referring to the charging train (charging series) shown in Table 1 below, when the friction portion 28b of the medicine throwing portion 28 and the wrapping paper 15 are rubbed, positive charges are concentrated in the vicinity of the friction portion 28b and positively charged. It will be in the state. When the positive charge is concentrated in the vicinity of the friction portion 28b, the negative charge is unevenly distributed in the vicinity of the opening 28a, and the vicinity of the opening 28a is negatively charged. As a result, the powder passing through the drug drop 28 is attracted to and adhering to the vicinity of the negatively charged opening 28a, and there is a high possibility of causing a problem in prescription of the drug.

  Therefore, based on such knowledge, in the present embodiment, positive ions are generated from the electrode 32 of the ion generator 70, and this is irradiated to the vicinity of the opening 28a of the drug throwing portion 28 to eliminate the charging in the vicinity of the opening 28a. It is set as the structure which prevents adhesion of the powdered medicine in the vicinity of the opening 28a.

  The wrapping paper 15 is a bag-like half bag-like product in which a closing portion 15a corresponding to the lower end portion of the belt-like sheet 13 (sheets 13a and 13b) is joined. The electrode 32 is located on the inner side of the wrapping paper 15 and is located on an extension line of the distal end portion of the medicine dropping portion 28 of the hopper 20. Therefore, if an air discharge is generated in the electrode 32 during the movement of the wrapping paper 15, ions generated thereby flow on a slight air flow generated along with the movement of the wrapping paper 15, and the medicine throwing portion 28. To reach. That is, in the medicine packaging device 1 of the present embodiment, the packaging paper 15 functions as an ion conduction path that guides ions generated by the air discharge to the medicine throwing portion 28, and the opening 28 a of the medicine throwing portion 28 and this In the vicinity, ions are intensively irradiated. Thereby, the charged state in the vicinity of the opening 28a is smoothly eliminated, and adhesion of powdered medicine is prevented.

The drive device 35 has a main part constituted by racks 36 and 37 arranged in parallel in the vertical direction and a pinion 38 that meshes with the racks 36 and 37. The racks 36 and 37 are installed with the tooth portions 36 a and 37 a facing the pinion 38, respectively, and maintain a horizontal state with the rotation of the pinion 38 and move close to and away from the hopper 20.

  The rack 36 is located above the pinion 38. Above the rack 36, a container 34 for receiving a tablet dispensed from the tablet supply unit 6 and dispensing it to the hopper 20 is attached.

  The rack 37 is located below the pinion 38. A shutter plate 39 is attached to the rack 37 as shown in FIG. The shutter plate 39 has a rising portion (rising portion 39a) that rises upward from the bottom surface side of the rack 37, and a portion (blocking portion 39b) that protrudes toward the hopper 20 side.

  When the drive device 35 rotates the pinion 38 to bring the rack 37 close to and away from the hopper 20, the opening portion on the top surface side of the tablet passage 23 in which the closing portion 39 b is provided in the hopper 20 in conjunction with this. Slide along. Therefore, as shown in FIG. 10B, the driving device 35 can close the tablet passage 23 by the closing portion 39b by operating the pinion 38 and causing the rack 37 to protrude toward the hopper 20 side. In addition, as shown in FIG. 10C, the driving device 35 can move the container 34 above the hopper 20 by operating the pinion 38 and projecting the rack 36 toward the hopper 20.

  The packaging unit 40 is for sealing the half-sack-shaped packaging paper 15 filled with the medicine in the hopper 20 to form a sealed bag. As shown in FIG. 11, the packaging unit 40 has a configuration in which a packaging paper transport unit 43 and a seal unit 45 are provided inside a box body 41.

  The box 41 has an inlet 46a for the wrapping paper 15 at a position adjacent to the hopper 20 and an outlet 47b on the opposite side. The wrapping paper transport unit 43 is provided on the inlet 46 a side of the box body 41. The wrapper paper transport unit 43 includes a support unit 47 and a drive unit 48.

  The support portion 47 is a portion that supports the wrapping paper 15 filled with the medicine from below (the closed portion 15 a side) and guides it toward the inside of the box body 41. The drive unit 48 includes rollers 50 and 51 and a motor 52. In FIG. 11A, the roller 51 is omitted for the sake of illustration, but the rollers 50 and 51 are formed of the sheet 13 (sheet) of the wrapping paper 15 entering from the inlet 46a side as shown in FIG. 13a, 13b) is installed at a position where the vicinity of the end on the upper end (opening portion 15b) side of the overlapping portion can be sandwiched. The roller 50 is a driving roller that rotates under the power of the motor 52. By operating the motor 52, the packaging unit 40 can feed the packaging paper 15 toward the seal portion 45 with the rollers 50 and 51 sandwiching the packaging paper 15.

  A so-called stepping motor is adopted as the motor 52, and the rotating shaft rotates by a certain angle by inputting a predetermined electric signal (pulse signal). Therefore, the packaging unit 40 can adjust the amount of progress of the packaging paper 15 by adjusting the number of pulses of the electric signal input to the motor 52.

  As shown in FIG. 11, the seal portion 45 includes a first seal block 53 and a second seal block 55. As shown in FIG. 11B, the first seal block 53 is installed so that the fusion pieces 53a and 53b face each other, and the fusion pieces 53a and 53b are close to and away from each other. Also, the second seal block 55 is also installed so that the fusion pieces 55a and 55b face each other, and these are installed so as to be close to and away from each other. The fusion pieces 53a and 53b and the fusion pieces 55a and 55b generate heat when energized. The fused pieces 53a and 53b and the fused pieces 55a and 55b are arranged with an interval enough to allow the wrapping paper 15 to pass in a state of being separated from each other.

  As shown in FIG. 11A, the fusion piece 53 a has a substantially “L” shape, and is roughly divided into an upper end fusion portion 56 and a downstream end fusion portion 57. The upper end fusion part 56 is a portion that extends in the direction in which the wrapping paper 15 advances when the wrapping paper 15 enters the box 41 of the packaging unit 40. The upper end fused portion 56 is arranged at a position where the upper end side of the wrapping paper 15, that is, the vicinity of the end portion on the open portion 15 b side where the sheet 13 (sheets 13 a and 13 b) is not yet sealed passes. Further, the downstream end fusion part 57 is adjacent to the position on the downstream side in the advancing direction of the wrapping paper 15 with respect to the upper end fusion part 56 (the right side in FIGS. 12A and 12B). It extends downward with respect to the wearing part 56. The fused piece 53b is a member having the same shape and size as the fused piece 53a. The fusion pieces 53a and 53b are arranged so that the upper end fusion portions 56 and 56 and the downstream end fusion portions 57 and 57 are parallel to each other.

  As shown in FIG. 11A, the fusion piece 55 a has a substantially “L” shape, and is roughly divided into an upper end fusion portion 58 and an upstream end fusion portion 59. The upper end fusion part 58 is located on the extension line of the upper end fusion part 56 of the above-mentioned fusion piece 53a. The upstream end fusion part 59 is adjacent to the position on the upstream side in the traveling direction of the wrapping paper 15 with respect to the upper end fusion part 56 (left side in FIGS. 12A and 12B). It extends downward with respect to 58. Further, the upstream end fusion part 59 is arranged with a slit-shaped gap with respect to the downstream end fusion part 57 of the above-described fusion piece 53a. The fusion piece 55b is a member having the same shape and size as the fusion piece 55a, and is arranged so that the upper end fusion portions 58, 58 and the downstream end fusion portions 59, 59 are parallel to each other. .

  As described above, the seal portion 45 has a configuration in which the first seal block 53 and the second seal block 55 are arranged side by side in the traveling direction of the wrapping paper 15 entering from the inlet 46a. Therefore, when the motor 52 is operated to feed the wrapping paper 15 into the seal portion 45 and the first seal block 53 and the second seal block 55 are operated, first, as shown by hatching in FIG. The end portions on the upper end side (opening portion 15 b side) of the wrapping paper 15 and the end portions on the downstream side in the traveling direction of the wrapping paper 15 are sealed by the fusion pieces 53 a and 53 b of the block 53.

  Thereafter, the motor 52 is operated to feed the wrapping paper 15 by a distance corresponding to the upper end fusion part 56 of the fusion pieces 53a and 53b, and the fusion pieces 55a and 55b of the second seal block 55 are brought close to each other. As shown by hatching in FIG. 12B, the end on the upper end side (opening portion 15b side) of the wrapping paper 15 and the end on the upstream side in the traveling direction of the wrapping paper 15 are sealed and sealed. A medicine package 60 is formed. When the motor 52 is further operated, the medicine is discharged from the outlet 46 of the seal portion 45 in a state where the medicine is sealed one by one by the packaging paper 15.

  Next, the operation of the medicine packaging device 1 of this embodiment will be described in detail with reference to the flowchart shown in FIG. The medicine packaging apparatus 1 sets the tablets and powders in the tablet supply unit 6 and the powder supply unit 7 and then turns on a start switch (not shown) to turn on the sheet 13 constituting the packaging paper 15 in step 1 and step 2. (Sheet 13a, 13b) A part of the sheet 13a and 13b is bonded to form a half-sack, and the tablet supply unit 6 and the powder supply unit 7 discharge the tablets and powders into the wrapping paper 15 through the hopper 20. Operation is performed.

  More specifically, when the start switch is turned on, in step 1, the sheet 13 (sheet) that forms the wrapping paper 15 by the fusion pieces 53 a and 53 b of the first seal block 53 provided inside the seal portion 45. The parts on the downstream end side of 13a, 13b) are sealed (adhered). Thereby, the wrapping paper 15 is in a half-sack-like state in which the portions other than the portion on the upstream end side in the traveling direction are closed as shown in FIG.

  Further, when the bonding operation of the wrapping paper 15 is performed in Step 1, the dispensing operation is performed almost simultaneously with this. That is, in the medicine packaging device 1, when the activation switch is turned on, the pinion 38 of the driving device 35 provided at a position adjacent to the hopper 20 is operated, and a plurality of tablet storage units provided in the tablet supply unit 6 are operated. The container 34 moves below the 8. When the container 34 reaches below the tablet accommodating part 8 in which the tablets to be prescribed are accommodated, the bottom plate of the tablet accommodating part 8 is opened, and the tablets accommodated therein are dispensed into the container 34. When the tablet to be prescribed is accommodated in the container 34 in this way, the pinion 38 is actuated again, and the container 34 is moved directly above the tablet passage 23 of the hopper 20 as shown in FIG. Thereafter, the bottom plate of the container 34 is opened, and the tablets accumulated in the container 34 are discharged into the tablet passage 23. The tablet dispensed to the tablet passage 23 is dispensed through the medicine throwing portion 28 into the half-bag-shaped wrapping paper 15 by the above-described bonding operation.

  In Step 2, the powder filled in the basket 10 is charged into the divided container 11 disposed below, and charged into the powder container 12 provided in the divided container 11 in a substantially uniform manner. Thereafter, one bottom plate of the plurality of powder storage units 12 is opened, and the powder stored in the powder storage unit 12 is dispensed to the powder passage 25.

  Here, as described above, the opening on the lower side of the powder passage 25 is normally closed by the opening / closing plate 26. Therefore, the powder dispensed from the powder storage unit 12 once accumulates in the powder passage 25. After the powder is stored in the powder passage 25, the opening / closing plate 26 provided in the powder passage 25 is opened at a predetermined timing, so that the powder is dropped into the medicine throwing portion 28 and is discharged into the wrapping paper 15.

  Returning the description to the control flow, when the medicine is dispensed to the half-sack-shaped wrapping paper 15 in step 2 as described above, the control flow proceeds to step 3 and the packaging operation is started. In step 2, the medicine dispensed from the hopper 20 is packaged.

  More specifically, when the packaging operation is started, the rollers 50 and 51 of the seal portion 45 are operated, and the upper end of the first seal block 53 is moved downstream of the packaging paper 15 in the traveling direction (exit 46b side). The length corresponding to the fusion part 56 is advanced.

  Thereafter, the fusion pieces 53a and 53b of the first seal block 53 and the fusion pieces 55a and 55b of the second seal block 55 are operated in a direction close to each other. And as shown in FIG.12 (b), in the site | part by the side of the open part 15b of the sheet | seat 13 (sheet | seat 13a, 13b) sealed in the previous control flow by the upper end melt | fusion part 58,58 of a 2nd seal block. On the other hand, the position adjacent to the downstream side in the traveling direction of the wrapping paper 15 is sealed, and the upstream end fused portions 59 and 59 seal the opening portion on the upstream end side. Thereby, the medicine package 60 in which the medicine is packaged by the packaging paper 15 is completed.

  At the same time, the fusion pieces 53a and 53b of the first seal block 53 move in the approaching direction. As a result, as shown by a broken line in FIG. 12, the packaging paper 15 is sealed at a position adjacent to the medicine package 60 on the downstream side in the traveling direction of the packaging paper 15, and the medicine package 60 for the next prescription is Part is formed.

  When the medicine package 60 is completed as described above, the portions sealed by the downstream end fusion portions 57, 57 of the fusion pieces 53a, 53b and the upstream end fusion portions 59, 59 of the fusion pieces 55a, 55b. The boundary portion 61 with the sealed portion is cut by a cutter (not shown), and the medicine package 60 is divided from the packaging paper 15. The medicine package 60 divided from the wrapping paper 15 is discharged from an outlet 46 b provided in the box 41 of the seal portion 45.

  When the medicine package 60 is produced as described above, the control flow proceeds to step 4, and whether or not the produced medicine package 60 has reached n packages (n is a natural number) after starting the medicine packaging device 1. Is confirmed. Here, when the medicine package 60 produced after the activation switch is turned on does not reach the n-package, the production of the medicine package 60 has not progressed so much as described above when the next medicine package 60 is produced. There is a low possibility that the powder will adhere due to friction between the wrapping paper 15 and the medicine drop 28. Therefore, in this case, the control flow proceeds to step 5 described later.

  On the other hand, when the medicine package 60 produced after the activation switch is turned on in step 4 has reached n packages, the production of the medicine package 60 has progressed to some extent, and further production of the medicine package 60 continues. There is a high possibility that static electricity is generated due to friction between the wrapping paper 15 and the medicine throwing portion 28, and the vicinity of the opening 28 a is charged with a negative charge and the powder adheres. Therefore, in this case, the control flow proceeds to step 8, the irradiation flag is turned on, and ion irradiation to the medicine throwing portion 28 is started.

  More specifically, when the control flow proceeds to step 8, a positive high voltage is applied to the electrode 32 by the high voltage power supply 71 of the ion generator 70, and an air discharge occurs in the vicinity of the electrode 32.

  Here, as described above, the guide member 30 holding the electrode 32 and the tip portion of the medicine throwing portion 28 are inserted from the open portion 15 b side of the half-sack-shaped wrapping paper 15. Further, as shown in FIG. 5A, the wrapping paper 15 has a bowl-like shape in which the closing portion 15a on the lower end side is closed. Therefore, in the present embodiment, a path (ion conduction path) that connects the electrode 32 and the drug throwing portion 28 is formed by the wrapping paper 15. Therefore, when an air discharge occurs in the electrode 32, positive ions generated thereby are irradiated to the vicinity of the opening 28 a of the medicine throwing portion 28 by the wrapping paper 15. The positive ions generated here are engulfed in a slight air flow generated as the wrapping paper 15 advances toward the seal portion 45 and flows smoothly toward the opening 28a. Thereby, the charged state in the vicinity of the opening 28a is eliminated by the friction between the wrapping paper 15 and the medicine throwing portion 28, and adhesion of powdered medicine in the opening 28a and the vicinity thereof can be prevented.

  When ion irradiation is performed on the drug throwing portion 28 as described above, the control flow proceeds to step 5.

  When the control flow proceeds to step 5, it is confirmed whether or not the packaging operation should be terminated. If it is determined in step 5 that the packaging operation should be continued, the control flow is returned to step 2 and the above-described series of operations is repeated. On the other hand, in step 5, when the number of medicine packages 60 to be prepared by the packaging operation reaches a predetermined number N (N is a natural number) or when the packaging operation is forcibly terminated, the control flow will be described later. The process proceeds to step 6 to perform the dust collecting operation.

  More specifically, when the control flow shifts to Step 6, the pinion 38 of the drive device 35 is operated, and the rack 37 moves to the hopper 20 side. Accordingly, the inlet portion of the tablet passage 23 of the hopper 20 is closed by the closing portion 39b of the shutter plate 39 attached to the rack 37. Thereafter, the dust collector 29 is activated, and the powder remaining in the hopper 20 is collected.

  At a predetermined timing during the above-described dust collection operation or after the completion of the dust collection operation, the control flow proceeds to step 7 and the irradiation flag is turned off. Thereby, the air discharge in the electrode 32 is stopped, the ion irradiation to the medicine throwing portion 28 is finished, and a series of control flow is completed.

  In the medicine packaging apparatus 1 described above, when medicine packaging is started, the rollers 50 and 51 operate almost continuously, and the packaging paper 15 is continuously fed. Therefore, a slight air flow is generated in the vicinity of the wrapping paper 15 along the conveyance direction of the wrapping paper 15. Further, in the medicine packaging device 1, the electrode 32 is provided on the upstream side in the flow direction of the packaging paper 15 with respect to the medicine feeding section 28. For this reason, when the wrapping paper 15 is sequentially sent to the seal portion 45 side for the medicine wrapping, the ions generated by the air discharge in the electrode 32 flow to the medicine throwing portion 28 side together with the wrapping paper 15 to open the opening. The vicinity of 28a is reached, and the static electricity charged in the opening 28a can be neutralized. Therefore, according to the medicine packaging device 1, it is possible to prevent the powdered medicine from adhering to the vicinity of the opening 28 a of the medicine dispensing section 28 even if friction occurs between the packaging paper 15 and the medicine dispensing section 28.

  Further, as described above, in the medicine packaging device 1, both the electrode 32 and the medicine throwing portion 28 exist inside the bowl-shaped packaging paper 15. Therefore, in the medicine packaging device 1, the wrapping paper 15 becomes an ion conduction path through which ions generated by air discharge pass, and the ions can be concentratedly irradiated to the opening 28a of the medicine throwing portion 28 and the vicinity thereof. Therefore, the medicine packaging apparatus 1 can prevent the opening 28a and the vicinity thereof from being charged, powdered powder adhering to it and becoming dirty, or powdered medicine falling to an unexpected position and causing a sealing failure of the medicine pack 60.

  The medicine packaging apparatus 1 according to the present embodiment has a configuration in which the electrode 32 is arranged on the upstream side in the traveling direction of the packaging paper 15 from the medicine dispensing part 28 and directly irradiates the medicine dispensing part 28 with ions. be able to. Therefore, the medicine packaging apparatus 1 can irradiate most of the ions generated by the air discharge to the medicine drop 28 and can efficiently eliminate or prevent the charge of the medicine drop 28.

  In the above-described embodiment, the configuration in which the electrode 32 is arranged on the upstream side in the traveling direction of the wrapping paper 15 with respect to the medicine throwing portion 28 is illustrated, but the present invention is not limited to this, and the electrode 32 May be arranged on the downstream side of the medicine dropping portion 28. In this case, it is desirable that the electrode 32 is attached so that the tip extends from the downstream side in the traveling direction of the wrapping paper 15 to the upstream side, that is, in the direction from the seal portion 45 side to the support shaft 19 side. Further, in the case where the electrode 32 is attached to the downstream side of the drug drop 28, the electrode 32 is arranged such that the distal end portion (site near the opening 28a) of the drug drop 28 is located on the extension line as in the above embodiment. It is desirable to be attached.

  In the above embodiment, the configuration in which the electrode 32 is arranged inside the bowl-shaped wrapping paper 15 and the wrapping paper 15 is used as an ion conduction path is illustrated. As a reference invention, for example, as shown in FIG. 14, an electrode 32 is disposed on the outer side of the wrapping paper 15, and a cylindrical or bowl-shaped ion conduction path 75 from the vicinity of the electrode 32 to the vicinity of the opening 28 a of the drug throwing portion 28. It is good also as a structure which provided. Even in such a configuration, ions generated by applying a high voltage to the electrode 32 to cause an air discharge can be intensively irradiated in the vicinity of the opening 28a. When the ion conduction path 75 is provided as described above, the electrode 32 may be inside or outside the ion conduction path 75.

  The medicine packaging device 1 is installed with the electrode 32 held by the guide member 30. The electrode 32 is held at a position (intermediate portion) slightly above the lower end of the guide member 30. Therefore, even if the guide member 30 directly touches the wrapping paper 15, the electrode 32 does not touch or catch the wrapping paper 15. Therefore, in the medicine packaging device 1, the packaging paper 15 is not damaged by the electrode 32.

  Moreover, the guide member 30 can hold down the bottom part (blocking part 15a) of the wrapping paper 15 whose lower end part has a half bag shape from the open part 15b side. Therefore, in the medicine packaging device 1 according to the present embodiment, the bottom of the packaging paper 15 is pulled up and lifted by filling the packaging paper 15 with a large amount of medicine and the packaging paper 15 expanding. Can be prevented by the guide member 30.

  In the medicine packaging apparatus 1 of the present embodiment, the medicine throwing portion 28 is made of polystyrene resin, and the wrapping paper 15 is coated with polyethylene resin. It is assumed that positive charges are concentrated on the friction portion 28b and negative charges are concentrated near the opening 28a. Therefore, in this embodiment, a configuration is adopted in which a positive high voltage is applied to the electrode 32 to generate positive ions. Therefore, in the medicine packaging device 1, the charge in the opening 28a of the medicine throwing portion 28 and the vicinity thereof (protrusion end portion) can be neutralized to eliminate the adhesion of the medicine.

  In the above embodiment, in view of the fact that the drug drop 28 is made of polystyrene resin and the wrapping paper 15 is coated with polyethylene resin, a positive high voltage is applied to the electrode 32. The present invention is not limited to this. More specifically, referring to the charging train shown in Table 1, for example, even when the same packaging paper 15 as that in the above embodiment is adopted, the material of the medicine throwing portion 28 is made of vinyl chloride resin. In this case, the polarity of the charge is reversed from that in the above embodiment. That is, the friction portion 28b of the medicine throwing portion 28 is charged with a negative charge, and the opening 28a and the vicinity thereof are charged with a positive charge. Therefore, in this case, it is necessary to apply a negative high voltage to the electrode 32 in order to eliminate charging in the opening 28a and the vicinity thereof.

  As described above, in the present embodiment, the drive device 35 is provided at a position adjacent to the hopper 20, and the pinion 38 is operated to close the inlet of the tablet passage 23 of the hopper 20. Therefore, the medicine packaging device 1 can suppress a reduction in dust collection ability due to air being sucked from the tablet passage 23 side for tablets (solid medicine) when performing the dust collection operation.

  In the above embodiment, both the container 34 for receiving the tablet dispensed from the tablet supply unit 6 by the driving device 35 and the shutter plate 39 for closing the tablet passage 23 are operated. The present invention is not limited to this, and the drive sources for both may be provided separately. The driving device 35 uses a so-called rack and pinion mechanism configured by combining the racks 36 and 37 and the pinion 38, but is not limited to this, and the container 34 and the shutter are used using other mechanisms. It is good also as a structure which operates the board 39. FIG.

  Although the medicine packaging device 1 includes the shutter plate 39, the present invention is not limited to this, and the shutter plate 39 may be omitted. The shutter plate 39 is slid along the opening portion of the inlet of the tablet passage 23 to be closed. For example, a slit is provided in the middle of the tablet passage 23, and the shutter plate 39 is moved through the slit. It is good also as a structure made to go in and out.

  In the above embodiment, as illustrated in FIG. 13, the configuration in which the dust collecting operation is performed after the entire packing operation is completed is illustrated, but the present invention is not limited to this, and the packing operation and the collecting operation are illustrated. It is good also as a structure which implements dust operation | movement simultaneously. In such a configuration, ions irradiated on the medicine drop 28 during the packaging operation are taken into the hopper 20 from the opening 28a, and charging on the inner surface of the hopper 20 can be prevented or eliminated. .

  In the case where the dust collecting operation is performed in parallel with the packaging operation as described above, if a malfunction such as the powder medicine to be dispensed to the packaging paper 15 is expected to be sucked into the dust collecting device 29, the packaging is performed. The dust collection capability of the dust collector 29 during operation may be limited.

  As described above, in the medicine packaging device 1 of the present embodiment, a high voltage is applied to the electrode 32. Therefore, the medicine packaging apparatus 1 may be configured to include a warning unit such as a lamp that indicates that a high voltage is applied to the electrode 32 in order to prevent an unexpected accident or the like. Moreover, in order to ensure safety at the time of maintenance or the like, the medicine packaging device 1 may be configured to forcibly stop energization of the electrode 32 and stop the generation of ions when any error or the like occurs.

  In the above embodiment, as shown in the flowchart of FIG. 13 and the like, once ion irradiation is started, energization to the electrode 32 is continued until the packaging operation is completed. It is good also as a structure which stops electricity supply to the electrode 32 once whenever one is produced. According to such a configuration, power consumption in the electrode 32 can be minimized.
