  Next, the present invention will be described by taking up one embodiment. In addition, although the chemical | medical agent packaging apparatus of this embodiment is set as the structure which can package both a powder and a tablet, the structure which can package only either a powder or a tablet may be sufficient.

  The medicine packaging device 1 according to the present embodiment has the appearance shown in FIG. 1, and includes a medicine supply unit 12 that supplies medicine (powder and tablets) into a housing 11 serving as a container, and a medicine supply unit. A medicine packaging unit 13 (see FIG. 6) for packaging the medicine supplied from 12 in a sheet form is accommodated. In the case 11, a part of the powder supply hopper 121 (illustrated in a state where the opening is covered with a cover) of the medicine supply unit 12 and the tablet dispensing basket 122 are exposed. The constituent members other than these exposed portions are substantially isolated from the outside air of the medicine packaging device 1 by the housing 11. However, the isolation is not required to a level where the isolation is airtight, and is configured so that dust does not jump out of the housing 11 (for example, the cover of the medicine packaging device 1 or the edge of the inspection door). Is provided with a packing, and the inside of the housing 11 is kept at a negative pressure rather than outside air).

  As shown in FIG. 2, the portion of the medicine supply unit 12 that supplies the powder includes a vibration feeder 123 for sending out the powder from the powder charging hopper 121, and the powder supplied by the vibration feeder 123 is dropped and supplied. The rotary table 124 is provided. The turntable 124 includes a donut-shaped plate member that is configured to be rotatable around the longitudinal axis C1 and has a concave groove (see FIG. 6) formed in the circumferential direction.

  The part for supplying the powder includes a cutting device 125 that is rotatable around the horizontal axis C2 so as to cut a pile of the powder M deposited on the concave groove of the rotary table 124 from the vibration feeder 123, and the cutting device. And a hopper 126 arranged to receive the powder M cut out at 125. The lower end of the hopper 126 is a lower end opening 126a opened downward, and as shown in FIG. 5, an opening / closing lid 126b for opening and closing the lower end opening 126a is provided. The powder discharged from the lower end opening 126a is received by a packaging material (wrapping paper) S conveyed in the longitudinal direction as shown by a two-dot chain line in FIG. It is heat-sealed by the apparatus 131 and is packaged one by one.

  The portion of the medicine supply unit 12 that supplies tablets is not shown in the drawing, but the tablet for a single packet falls downward by the open / close shutter provided at the bottom of the tablet dispensing basket 122 and the hopper 126 is provided. In the same manner as in the case of the powder, it is received by the packaging material (wrapping paper) S and is packaged by the sealing device 131.

  In addition, as shown in FIG. 3, the medicine packaging device 1 includes a dust collection unit 2 that captures a powdery medicine present in the housing 1. The dust here refers to the dust derived from the powder remaining in the apparatus without being wrapped in the packaging material S, and the dust generated by cracking or scraping the tablet. The dust collection unit 2 according to the present embodiment includes three parts: a residual drug collection unit 21, a floating dust capture unit 22, and an internal dust collection unit 23.

  The remaining medicine collection unit 21 is provided mainly for collecting dust (residual medicine) adhering to each part constituting the medicine supply unit 12 and the medicine packaging unit 13, and during operation of the medicine packaging device 1, It is operated intermittently when the remaining drug treatment is required.

  On the other hand, the medicine packaging device 1 is provided outside the housing 11, communicates with the internal space of the housing 11, and is provided with a circulation vent 31 for circulating the air inside the housing 11. It has been. Due to this circulation vent 31, the air in the housing 11 becomes a substantially closed system. The remaining medicine recovery unit 21 captures dust contained in the air circulating through the circulation vent 31 and is located in the middle of the circulation vent 31. The residual drug recovery unit 21 and the circulation vent 31 constitute a residual drug recovery dust collecting unit U1. In other words, the residual drug collection dust collecting unit U <b> 1 includes the residual drug recovery unit 21 and the circulation vent 31.

  In the circulation vent 31, the end (suction port) on the upstream side of the remaining drug collection unit 21 is connected to the drug supply unit 12, the drug packaging unit 13, and the cleaning nozzle 41. Examples of the position of the suction port include the rotary table 124 or the vibration feeder 123 (see FIG. 4), or the upper part of the hopper 126 (see FIG. 5), but are not limited thereto. Note that an opening / closing valve 42 is provided in the air passage to the cleaning nozzle 41, and the opening / closing valve 42 is opened when the cleaning nozzle 41 is used. This cleaning nozzle 41 is used by an operator to suck up dust adhering to the powder injection hopper 121, the tablet dispensing basket 122, and the like.

  In the circulation ventilation path 31, an end (a discharge port) on the downstream side of the remaining medicine collection unit 21 is located inside the housing 11. The position of the spout in the inside of the housing 11 is not particularly limited, but can be a position where air current can be applied to portions where the dust is likely to adhere in the medicine supply unit 12 and the medicine packaging unit 13. For example, the inside (refer FIG. 6) of the hopper 126 is mentioned.

  The remaining medicine collection unit 21 has suction means (not shown). Examples of the suction means include a fan and a vacuum suction device, but are not limited thereto. By this suction means, it is possible to generate an air flow from the upstream side to the downstream side of the circulation ventilation path 31, and this air flow passes through the residual drug recovery unit 21.

  Here, an example in which the mouthpiece is positioned on the rotary table 124 will be described with reference to the rotary table cleaning unit 5 shown in FIG. The rotary table cleaning unit 5 is for removing powder (dust) remaining on the rotary table 124 after being cut out by the cutting device 125. The rotary table cleaning unit 5 has a brush body 51. The brush body 51 is configured to be switchable between a cleaning posture in which the outer peripheral portion can contact the rotary table 124 and a non-cleaning posture separated from the rotary table 124. The brush body 51 is rotatably provided around the rotation center axis 52. The rotation center shaft 52 is configured as a motor shaft of the rotation drive motor 53.

  The brush body 51 is covered with a covering body 54 that opens an area facing the rotary table 124. A joint pipe portion 55 is formed so as to protrude from the cover 54, and the joint pipe portion 55 is connected to the circulation ventilation path 31.

  In the rotary table cleaning unit 5, the powder body adhering to the rotary table 124 by rotating the brush body 51 can be sucked into the circulation air passage 31 as dust.

  Next, as an example in which the mouthpiece is positioned at the upper part of the hopper 126, a description will be given with reference to the hopper cleaning unit 6 shown in FIG. The hopper cleaning unit 6 includes two upper and lower rear dust collection ducts 61 and 62 arranged on the rear side of the upper end of the hopper 126, a front dust collection duct 63 arranged on the front side of the upper end of the hopper, and each dust collection duct. A connection hose (not shown) connected in communication. The connection hose is connected to the circulation vent 31.

  Further, as shown in FIG. 6, a spray nozzle 7 is provided inside the hopper 126. This is configured to be movable on an arcuate trajectory. The spray nozzle 7 applies an air flow to the inner surface of the hopper 126, thereby removing dust adhering to the hopper 126.

  In this hopper cleaning unit 6, the hopper 126 is hit by a hopper hitting means (not shown) to drop the powder adhering to the inner surface of the hopper 126, and the air current is applied from the tip of the spray nozzle 7 to the inner surface of the hopper 126. Thus, the powder adhering to the inner surface of the hopper 126 can be sucked into the circulation air passage 31 as dust.

  As shown in FIG. 3, the remaining medicine collection unit 21 of the present embodiment includes a front-stage dust collection unit 211 located on the upstream side in the airflow direction and a rear-stage dust collection unit 212 located on the downstream side in the airflow direction. The pre-stage dust collection unit 211 includes a filtration type dust collector, and prevents at least the passage of dust larger than the eyes of a filter (hepa filter or the like). This suppresses the passage of dust to the downstream side of the upstream dust collection unit 211. And the latter dust collection part 212 is equipped with an electric dust collector. The electric dust collector has a well-known structure and includes an electrode part and a filter part. The electrode part charges the dust passing through the electrode part positively or negatively. And a filter part adheres the said charged dust to the fiber of a filter by electrostatic force (Coulomb force). As a result, the passage of dust to the downstream side of the downstream dust collecting section 212 is suppressed. Thus, in this embodiment, since the residual medicine collection | recovery part 21 is a two-stage structure of the front | former stage dust collection part 211 and the back | latter stage dust collection part 212, dust collection efficiency can be improved. The upstream dust collection unit 211 and the downstream dust collection unit 212 have different dust collection principles. The upstream dust collection unit 211 captures relatively large dust, and the downstream dust collection unit 212 captures relatively small dust. . Thus, dust collection efficiency can be further improved by having the some dust collection parts 211 and 212 with which the residual medicine collection | recovery parts 21 are arrange | positioned in series, and the dust collection principles differ.

  In addition, although the remaining medicine collection | recovery part 21 of this embodiment is set as the two-stage structure of the front | former stage dust collection part 211 and the back | latter stage dust collection part 212, you may be comprised by three or more steps | paragraphs. In addition, the front dust collection unit 211 and the rear dust collection unit 212 may be dust collection units having the same dust collection principle. Moreover, as the dust collector which the residual medicine collection | recovery part 21 has, the cyclone type dust collector which collects dust by making an airflow into a spiral form other than the said filtration type dust collector and an electric dust collector can be illustrated. A dust collecting device based on another dust collecting principle may be used.

  In the remaining medicine recovery unit 21, at least the filter part is a cartridge type. Specifically, a part of the piping that constitutes the circulation ventilation path 31 and the filter portion are configured to be removable from other parts of the piping. As a result, even when the filter part is clogged and needs to be replaced, the operator does not touch dust composed of high-risk chemicals adhering to the filter part, and the filter part can be removed from the filter part during replacement. The filter part can be replaced without dropping off the dust. Therefore, the safety at the time of maintaining the remaining medicine collection | recovery part 21 is high. In order to make it possible to remove a part of the piping that constitutes the circulation vent 31 and the filter portion (pre-stage dust collecting portion 211), a flange 311 is provided in the piping that constitutes the circulation vent 31 as shown in FIG. Is provided. As a structure which can be removed, various means such as a threaded joint and a clamp may be used in addition to the flange.

  Since the air flow circulates through the inside of the medicine packaging device 1 by the circulation vent 31, the exhaust from the remaining medicine collection unit 21 is not released to the outside of the device. For this reason, even if a very small amount of dust is mixed in the exhaust, it does not float outside the medicine packaging device 1. Therefore, even if the medicine is highly dangerous, the medicine packaging device 1 enables the dispensing operator to safely perform the dispensing work.

  Next, the floating dust capturing unit 22 is provided mainly for collecting dust floating in the housing 11, and is always operated while the medicine packaging device 1 is in operation. Similarly to the circulation ventilation path 31, the medicine packaging device 1 is located outside the housing 11, communicates with the internal space of the housing 11, and circulates to circulate the air in the housing 11. An air passage 32 is provided. The floating dust trap 22 captures dust contained in the air circulating through the circulation vent 32 and is positioned in the middle of the circulation vent 32. The floating dust capturing unit 22 and the circulation ventilation path 32 constitute a dust collecting unit U2 for capturing floating dust. In other words, the dust collection unit U <b> 2 for capturing suspended dust has the suspended dust capturing unit 22 and the circulation ventilation path 32.

  In the circulation air passage 32, an end (suction port) on the upstream side of the remaining medicine collection unit 21 is opened in the housing 11. The position of the mouthpiece in the housing 11 can be close to a position where dust is easily generated, but is not particularly limited. Further, in the circulation ventilation path 32, an end portion (a discharge port) on the downstream side of the remaining drug collection unit 21 is also opened in the housing 11.

  Similar to the residual drug recovery unit 21, the suspended dust trapping unit 22 has a suction means (not shown). By this suction means, it is possible to generate an air flow from the upstream side to the downstream side of the circulation ventilation path 32, and this air flow passes through the suspended dust trap 22. In addition, the airflow generated by the suction means included in the suspended dust capturing unit 22 of the present embodiment is set to be weaker than the airflow generated by the suction means included in the residual drug recovery unit 21. The reason is that the residual drug recovery unit 21 peels off the dust (residual drug) adhering to each part of the drug supply unit 12 and the drug packaging unit 13 from the surfaces of the components of the drug supply unit 12 and the drug packaging unit 13. This is because the floating dust capturing unit 22 only needs to be able to capture the dust contained in the air circulating through the circulation ventilation path 32. Thus, dust collection can be performed efficiently by providing the strength of the air flow between the residual drug recovery unit 21 and the floating dust capturing unit 22.

  The floating dust capturing unit 22 may include a dust collecting device based on various dust collecting principles. Examples thereof include, but are not limited to, a filtration dust collector, an electric dust collector, and a cyclone dust collector.

  Further, in order to make it possible to remove a part of the piping that constitutes the circulation ventilation path 32 and the suspended dust trapping portion 22, a flange 321 is provided in the piping that constitutes the circulation ventilation path 32 as shown in FIG. Yes.

  By the way, the powder supply hopper 121 of the medicine supply unit 12 is provided with an opening 11a in the casing 11 so that the powder operator can supply the powder, and the powder supply hopper 121 is located in the opening 11a. To do. In order to prevent dust generated when powder is introduced from the opening 11a from jumping out of the medicine packaging device 1, for example, as shown in FIGS. Can be considered.

  The configuration shown in FIG. 7A is such that the air flow circulating through the circulation air passage 32 is discharged so as to coincide with the edge of the opening 11a, and the discharge portion 321 is opposed to the opening 11a. And a suction portion 322 for sucking an airflow circulating through the circulation ventilation path 32. With this configuration, it is possible to generate an air flow F1 from the discharge unit 321 toward the suction unit 322 so as to cross the opening 11a. By this air flow F1, it is possible to suppress the dust generated in the powder charging hopper 121 from jumping out of the medicine packaging device 1 when the powder is charged into the powder charging hopper 121. The air flow F1 is set to a flow velocity that is weak enough that the powder does not scatter even when the powder crosses the air flow F1 when the powder is charged into the powder supply hopper 121. Further, the air flow F1 is constantly flowed during the operation of the medicine packaging device 1.

  On the other hand, the configuration shown in FIG. 7B includes a discharge portion 323 that coincides with the edge of the opening 11a and discharges the airflow that circulates through the circulation vent path 32 downward in the drawing. This airflow merges with the circulation ventilation path 32 in the housing 11. With this configuration, it is possible to generate, for example, a spiral air flow F <b> 2 that extends along the inner surface of the powder supply hopper 121 and reaches the vibration feeder 123. Like the air flow F1, the air flow F2 can suppress dust from jumping out of the medicine packaging device 1 from the opening 11a. The air flow F <b> 2 is also set to a flow velocity that is weak enough to prevent the powder to be charged from splashing when the powder is charged into the powder supply hopper 121. Further, this air flow F2 is also constantly flowed during operation of the medicine packaging device 1.

  FIG. 7B shows an example in which the shape of the powder charging hopper 121 is a hemispherical shape whose inner surface is a curved surface, but it may be conical or pyramidal, and the shape of the powder charging hopper 121 is not particularly limited. The inner surface of the powder injection hopper 121 can be a smooth surface in order to suppress the adhesion of the powder.

  Next, the internal dust collecting unit 23 circulates unlike the remaining drug collecting unit 21 and the floating dust capturing unit 22, which is different from those located outside the housing 11 in combination with the circulation vents 31 and 32. It is integrated with the air passage 33 and is located inside the housing 11. The internal dust collection unit 23 and the circulation ventilation path 33 constitute an internal dust collection unit U3. In other words, the internal dust collection unit U3 includes the internal dust collection unit 23 and the circulation ventilation path 33.

  Since the internal dust collection unit 23 can have the same configuration as the residual drug collection unit 21 or the floating dust capturing unit 22 except for the positional relationship with respect to the case 11, a detailed description thereof will be omitted. Since the dust collection unit does not protrude from the housing 11 by being positioned inside, the shape of the medicine packaging device 1 can be made compact.

  As described above, the medicine packaging device 1 of the present embodiment includes a plurality of dust collection units U1, U2, and U3 that are sets of the circulation ventilation paths 31, 32, and 33 and the dust collection units 21, 22, and 23. Thereby, dust collection can be performed efficiently and even if the medicine handled by the medicine packaging device 1 is a highly dangerous medicine, the dispensing operator can safely perform the dispensing work. In addition, the combination of the residual medicine collection | recovery part 21, the floating dust capture | acquisition part 22, and the internal dust collection part 23 in the dust collection part 2 is arbitrary, The danger of the chemical | medical agent handled by the chemical | medical agent packaging apparatus 1, or the chemical | medical agent packaging apparatus 1 What is necessary is just to comprise the dust collection part 2 by an appropriate combination according to the installation condition.
