To close the shutter, as shown in FIG. 7, the motor 36 is rotated forward in the direction of the arrow shown by the solid line. As a result, the driving force of the motor 36 is transmitted to the first drive gear 41 through the motor gear 39, and the drive shaft 37 rotates in the direction of the arrow a. The driving force of the drive shaft 37 is not transmitted to the second drive gear 43 by the second one-way clutch 48, and the second drive gear 43 idles. However, the driving force of the drive shaft 37 is transmitted to the drive pulley 42 via the first one-way clutch 44, and is further transmitted to the driven pulley 28 of the delivery roller 12 through the belt 45. As a result, the delivery roller 12 rotates in the direction of the arrow, the shutter body 11 is sent out in the direction of the arrow to move down, and the entire surface of the tablet cassette shelf 2 is closed. As the shutter body 11 is sent out, the take-up shaft 13 rotates, and the driven gear 33, the intermediate gear 49, and the second driving gear 43 rotate, and the second driving gear 43 is described above. As described above, the drive shaft 37 is not affected because it is in the idle state.

When the shutter main body 11 is wound around the winding shaft 13, as shown by the dashed-dotted line in FIG. 5, the winding diameter of the shutter main body 11 increases, and the feed roller 12 and the winding shaft 13 are wound. ), The movement path of the shutter body 11 changes. In consideration of the increase in the winding diameter, a winding space is formed around the winding shaft 13. In the conventional garage shutter, the winding shaft is provided at the upper end of the guide rail. In the present invention, the winding shaft 13 is the upper rear of the shutter body 11, that is, the upper rear of the tablet cassette shelf 2. Since it is provided in the part, even if the winding space is formed around the winding shaft 13, it is not seen from the front, but external appearance is good.

As a result, the driving force of the motor 36 is transmitted to the first drive gear 41 via the motor gear 39, and the drive shaft 37 rotates in the direction of the arrow b. The driving force of the drive shaft 37 is not transmitted to the drive pulley 42 by the first one-way clutch 44, and the drive pulley 42 idles. However, the driving force of the drive shaft 37 is transmitted to the second drive gear 43 through the second one-way clutch 48, and furthermore, of the take-up shaft 13 through the intermediate gear 49 and the driven gear 33. It is transmitted to the central axis 29. As a result, the take-up shaft 13 rotates in the direction of the arrow, the shutter main body 11 is wound in the direction of the arrow, and moves to the same, and the entire surface of the tablet cassette shelf 2 is opened. As the shutter main body 11 is wound, the feed roller 12 rotates, and the driving pulley 42 rotates through the belt 45. Since the driving pulley 42 is idle, as described above, the driving shaft ( 37) does not affect.

The chemical | medical agent packaging apparatus 1 of this embodiment is installed in a hospital or a pharmacy, and the shutter of the tablet cassette shelf 2 is opened during preparation work. A pharmacist operates this chemical | medical agent packaging apparatus 1, and packs a tablet or a powder based on prescription data. When the preparation operation is finished, the shutter is closed, so that no person other than a pharmacist can take out the tablet cassette 9. Thus, there is no fear of taking the tablets or incorporating foreign substances or other tablets.

And even in the preparation service, the shutter of the tablet cassette shelf 2 can be closed. That is, the medicine packing apparatus 1 is operated with the shutter closed, tablets and powdered medicines are packaged according to the prescription data, and when a defect occurs in the tablet cassette 9, the shutter is opened and the tablet is purified in the corresponding tablet cassette 9. May be supplemented.

The shutter device 10 can perform control to stop at each stage of each stage (up and down seven stages in the embodiment of FIG. 1) of the tablet cassette shelf 2 by pulse control of the motor 36. In this case, since the winding diameter of the shutter main body 11 in the winding shaft 13 increases when the shutter main body 11 is wound, the pulses at the stop of each step by the pulse control of the motor 36 are increased. The number is not a constant interval, but it is necessary to shorten the interval as it is opened. That is, if it is 0 at the time of full closing, 23 pulses at the 7th stage opening, 34 pulses at the 6th stage opening, 43 pulses at the 5th stage opening, 52 pulses at the 4th stage opening, 61 pulses at the 3rd stage opening, 69 pulses for the second stage opening and 76 pulses for the total opening.

Then, a beam sensor, a hall IC sensor, and a contact sensor are provided at each stage of the tablet cassette shelf 2, and the motor 36 is stopped when the lower end of the shutter body 11 is detected by these sensors. It may be stopped at each stage.

An operation of stopping and opening the shutter device 10 at each step will be described in more detail. When the medicine packaging device 1 is powered on, authentication is performed by password, fingerprint authentication, or the like. If a defect occurs in the tablet cassette 9 during the packaging operation, the packaging operation is stopped and the defect is displayed. Specifically, on the screen corresponding to the arrangement of the tablet cassette 9 displayed on the display of the control device 5, the part corresponding to the tablet cassette 9 in which the shortage is generated blinks in red and The red LED (not shown) of the motor base 8 of the tablet cassette 9 is turned on. When a plurality of tablet cassettes 9 are missing, a plurality of points on the screen blink to light up a plurality of LEDs. Next, the shutter main body 11 is opened to the upper side of the tablet cassette 9 in which defects have occurred. As a result, the tablet cassette 9 whose LED is lit can be taken out to replenish the tablet. In the case where defects occur in the plurality of tablet cassettes 9, the shutter body 11 is opened to the upper side of the tablet cassette 9 on the upper side. When tablets are replenished in the defective tablet cassette 9 and a start button (not shown) is pressed, the shutter main body 11 is closed and the packaging operation is resumed. When the plurality of tablet cassettes 9 are defective and only one tablet cassette 9 is replenished and the start button is pressed, the shutter body 11 is closed once, but the defects of the remaining tablet cassettes 9 are further detected and again. The shutter body 11 is opened. And before opening the shutter main body 11, you may make it authenticate a user with a fingerprint or a password. In addition, the shutter opening and closing time can be shortened by installing the tablet cassette 9 containing tablets with high frequency of use below and the tablet cassette 9 containing tablets with low frequency of use.

In this way, when the tablet cassette 9 is defective, the shutter body 11 is opened by the minimum amount necessary until the tablet cassette 9 can be taken out, so that the confirmation of the missing tablet cassette 9 is confirmed. It becomes easy and improves safety. And since the shutter opens automatically at the time of absence, the user does not need to open the shutter each time. Moreover, since the shutter is always closed, the light shielding chemical can also be stored.                     

In addition, in the said embodiment, although the feed roller 12 and the winding shaft 13 were driven using one motor 36, you may drive with each individual motor.

In the above embodiment, the shutter device 10 is provided in the tablet cassette shelf 2 of the medicine packaging device 1, and the tablet cassette storage shelf or powder which is not shown in the vicinity of the medicine packaging device 1 is provided. The same shutter device 10 can be installed in the bottle storage shelf. Furthermore, the same shutter device 10 can be provided not only on the tablet cassette but also on the medicine cassette shelf of the medicine packaging device in which the medicine cassette is mounted.

As apparent from the above description, according to the present invention, since a shutter is provided to open and close the front surface of the medicine shelf in which a plurality of medicine containers are placed, when the medicine shelf is closed with a shutter after the pharmacist's work is finished, the medicine container is not concerned. There is no fear of being removed by the chair and it is safe.

Then, the inner surface of the shutter is supported by the delivery roller provided in the upper front part of the medicine shelf so as to be able to be fed out, and the upper end of the shutter is mounted on the winding shaft provided in the upper rear part of the medicine shelf, and a small delivery roller is applied Since it is located in the upper front part of a shelf and a large winding shaft is located in the upper back part of a chemical | medical agent shelf, the upper front part of a chemical | medical agent shelf does not become large, and external appearance is not damaged.

Furthermore, when the shutter is homologous, the feeding roller is driven in the winding direction and the idling roller is idly rotated. When the shutter is lowered, the feeding roller is driven in the feeding direction and the winding shaft is idling. Even if there is no guide of the shutter between the winding shaft and the winding shaft, the shutter can be moved up and down smoothly without loosening the shutter.

Since the driving device drives the winding shaft and the feeding roller through the one-way clutch, the shutter can be driven by one driving device, and the structure and arrangement of the driving device can be simplified.
