Description

Pharmaceutical packing machine {packaging machine for medicine}

The present invention relates to a pharmaceutical packaging machine.

BACKGROUND ART Conventionally, some medicine packing machines have medicines stored in annular grooves formed on a disc, and are ejected and packaged one by one using a drawing-out device (for example, Japanese Patent Publication 7). -10684, Japanese Unexamined Patent Publication No. 6-39789. In such a packing machine, since the chemical | medical agent may remain in an annular groove | channel, it is made to clean | clean the chemical | medical agent which remained after a packaging operation by the cleaner apparatus. The cleaner device is provided with a brush which rotates about the support shaft orthogonal to the radial direction of the said disk, and draws the chemical | medical agent discharged | emitted in the radial direction by a suction device.

However, in the conventional medicine packing machine, the ejection direction by the brush is the radial direction of the disk, and there is a problem that it scatters around.

In addition, there are also the following problems. That is, the brush for extinguishing the medicine from the annular groove has a cylindrical shape with the same radius of curvature as the annular groove, and the occupied space is large. In addition, when the cleaning operation is not performed, since the chemical agent attached to the brush falls, it is necessary to sufficiently clean the brush. And it is difficult to completely remove the chemical | medical agent in an annular groove only by the extinguishing by a brush.

Then, an object of this invention is to provide the chemical | medical agent packaging machine which can be cleaned at least, preventing the scattering of the chemical | medical agent accommodated in the disk-shaped annular groove.

3, the cleaner device 11 which is a characteristic part of this invention is provided in the said powder supply supply part 5 (FIG. 3, the chemical | medical agent feeder 6 and the ejection apparatus 8 are abbreviate | omitted. }. As shown in FIG. 4, this cleaner apparatus 11 attaches the cover member 14 and the brush member 15 to the base 12 through the support piece 13 so that rotation is possible.

The suction duct 16 is attached to the base 12. The suction duct 16 connects the vertical pipe 17 and the horizontal pipe 18. In the horizontal pipe 18, the guide ring 19 is fitted in the edge part by the suction port side, and the bending part is formed in the vicinity. A suction device (not shown) is connected to the vertical pipe 17 at an end opposite to the connection position with the horizontal pipe 18.

The support piece 13 has a vertical wall 20 at one end and a horizontal wall 21 extending horizontally from the lower edge thereof. The horizontal wall 21 is fixed to the base 12, and the vertical wall 20 is formed with a through hole 20a through which the guide ring 19 passes. The mounting plate 22 is fixed to the other end side of the support piece 13, and the rotation position detection sensor 24 is mounted thereon via the sensor bracket 23, and the cover motor 25 capable of forward and reverse rotation driving is provided. Is mounted. The cam 27 provided with the magnet 26 which is a part to be detected is fixed to the rotating shaft of the cover motor 25, and is connected to the cylindrical part 14a of the cover member 14. As shown in FIG.

The cover member 14 has a substantially box shape in which the lower surface is opened, and is curved so that the lower side edge portion follows the annular groove 9 of the disc 7. A brush motor 28 is provided on one end surface of the cover member 14, and the rotary shaft thereof protrudes into the cover member 14 and is connected to a brush member 15 to be described later. And the other end surface of the cover member 14 is formed with the cylindrical part 14b, The said guide ring 19 is connected there. As a result, air inside the cover member 14 can be discharged from the guide ring 19 through the suction duct 16.

As shown in Fig. 5, the brush member 15 has a circular arc shape along the cross-sectional shape of the brush portion 31 composed of a plurality of brushes and the annular groove 9 in the cylindrical core material 30. The pin part 32 which consists of a pair of fins is provided. The core 30 is made of, for example, ABS resin, and fitting holes 33 are formed at both end surfaces thereof. Each of the fitting holes 33 is fitted with a rotating shaft of the brush motor 28 and support pins 34 (see FIG. 4) rotatably supported through the other end surface of the cover member 14, respectively. . As a result, when the brush motor 28 is driven, the brush member 15 rotates around the axis of the core material 30. Then, on the outer circumferential surface of the core material 30, a groove portion 35 extending in the longitudinal direction at a symmetrical position and joining the fins, and a mounting hole 36 to which the brush is fitted to a plurality of places are formed, respectively. have. Each fin is made of silicone sponge or foamed silicone, and the brush is made of nylon. As shown in FIG. 6, the brush member 15 rotates in the position which made the center line C of the core material 30 which is an axis | shaft approach the disk 7 side rather than the center of curvature O of the annular groove 9 In this way, the brush part 31 has an external shape capable of sweeping out the medicine in the annular groove 9. For example, the brush member 15 is formed such that the distal end positions of the pin portion 32 and the brush portion 31 are positioned on the outer surface obtained by rotating the substantially elliptical virtual board member about its long axis. . For this reason, the cleaner apparatus 11 can be made compact, it becomes possible to suppress the occupied space in a chemical | medical agent packaging machine, and to miniaturize the chemical | medical agent packaging machine itself.

The cleaner apparatus 11 of the said structure is arrange | positioned so that the shaft center of the brush member 15 may substantially correspond to the radial direction of the disk 7. Then, as the cover motor 25 is driven in the forward rotation, as shown in FIG. 7A, the opening of the cover member 14 is positioned below, and the brush member 15 is the annular groove 9 of the disc 7. Positioned at the cleaning position located in the inside, and the cover motor 25 is driven in reverse rotation, so that the opening of the cover member 14 is located upward, as shown in FIG. 7B, and the brush member 15 is an annular groove. It is positioned at the retracted position to retract from (9).

Next, the operation of the medicine packaging machine will be described. Since the packaging operation of the chemical | medical agent is the same as before, in the following description, it mentions only the cleaning operation of the disk 7.

That is, when all the medicines accommodated in the annular groove 9 of the disc 7 are exhausted by the ejection apparatus 8, the cleaner apparatus 11 is driven, and the cover member 14 is rotated to brush the member 15. Is positioned at the sweeping position shown in Figs. 7A and 8A, which is capable of sweeping out the medicament remaining in the annular groove 9 of the master disc 7. And the chemical | medical agent which remains in the annular groove 9 is wiped out by driving the brush motor 28 while rotating the disk 7. At this time, the brush member 15 is rotated so that the sweeping direction of the medicine is reverse to the rotational direction of the disc 7. Thereby, the sliding speed by a brush and a fin becomes high, and high speed rotation of the brush member 15 and the disc 7 becomes unnecessary. And the hop-in apparatus which is not shown in figure is driven. Thereby, the chemical | medical agent sweeped out is discharged | emitted from the inside of the cover member 14 through the suction duct 16. In this case, even if the chemical | medical agent sweeped out was scattered, the scattering direction is on the disk 7 and the direction which the cleaner apparatus 11 faces at the same time. In addition, the brush member 15 sliding the annular groove 9 is configured to include not only a brush but also a fin. As a result, most of the remaining medicine is wiped off by the brush, and the remaining slight medicine is surely wiped off by the fin. Therefore, the chemical | medical agent does not remain in the annular groove 9, and can be swept away reliably and discharged through the suction duct 16. FIG.

When removal of the chemical | medical agent remaining in the annular groove 9 is completed as mentioned above, the cover motor 25 is driven, the cover member 14 is rotated from FIG. 8A to FIG. 8B, and the cover member 14 is Positioning is carried out to the retracted position shown in Figs. 7B and 8C located below the brush member 15. Thereby, even if the chemical | medical agent adhered to the brush member 15 falls, it can be reliably prevented by the cover member 14, and it does not scatter to surroundings. In this case, it is preferable to continue the suction by the suction device for a while in preparation for the next cleaning.

In the above embodiment, the cover member 14 and the brush member 15 are rotated separately by the cover motor 25 and the brush motor 28, respectively, as shown in FIGS. 9 and 11. As can be seen, it is also possible to rotate with a single motor.

In FIG. 9, the one-way clutch 60 is attached to the cover member 14, and the rotating shaft of the motor 61 is connected. The drive gear 62 is integrated with the rotating shaft of the motor 61 and meshes with the driven gear 63 integrated with the core 30 of the brush member 15. The motor 61 drives forward and reverse rotation, and at the time of forward rotation, the one-way clutch 60 idles, and the brush member 15 is driven through the drive gear 62 and the driven gear 63 as shown in FIG. 10A. Only the rotation rotates, and the remaining medicine is swept away from the annular groove 9 of the disc 7. At the time of reverse rotation, as shown in FIG. 10B, the cover member 14 rotates through the one-way clutch 60, and the opening of the cover member 14 faces upward, and is attached to the brush member 15. Even if a drug falls, it does not fly around. 64 is a stopper, and restricts the rotation range of the cover member 14.

In FIG. 11, the core material 30 of the brush member 15 is connected to the one-way clutch 65 provided on the cover member 14. At the time of forward rotation of the motor 61, the one-way clutch 65 rotates idle, and only the driven gear 63 rotates. As in the case shown in Fig. 10A, the brush member 15 causes the disk 7 to be rotated. The remaining medicine is swept away from the annular groove 9. In the reverse rotation, the cover member 14 is rotated about the rotational axis of the motor 61 via the one-way clutch 65, so that the opening of the cover member 14 is similar to that shown in FIG. 10B. Is upward and does not fly around even if the chemical agent attached to the brush member 15 falls.

In addition, in the said embodiment, the brush member 15 was made to rotate centering around the core material 30 which the radial direction of the disc 7 extends, The core material 30 has the inner periphery of the annular groove 9, It may be arranged to cover the outer circumference. Thereby, scattering of the chemical | medical agent to the periphery of the disk 7 is prevented at least.

In addition, in the said embodiment, although the cover member 14 was made to rotate centering on the axis center extended in the radial direction of the disk 7, as shown to FIG. 12A-FIG. 12C, of the disk 7 You may make it rotate around the axis 70 orthogonal to a radial direction. The yaw is that when cleaning, the brush member 15 can slide in the annular groove 9 of the disc 7, and when not cleaned, the cover member 14 is positioned below the brush member 15. Any configuration may be used as long as it can be made.

As apparent from the above description, according to the present invention, since the brush portion is disposed so as to form a predetermined angle with respect to the direction orthogonal to the radial direction of the disk, the sweeping medicines may scatter around. It can be recovered reliably. In particular, by changing the external shape of the drug sweeping means, the space occupied in the vertical direction can be suppressed to have a compact configuration. Moreover, since the cover which covers the upper and lower sides of the chemical | medical agent sweeping means is provided by rotation, the fall of the chemical | medical agent when not cleaning can be prevented, and it becomes possible to omit the time and trouble of cleaning.
