As shown in FIG. 2, the circular distributor 11 and the distributor 6 of the powder dividing means having such a structure are driven and operated by a drive mechanism 20 which can be driven by one motor. It The drive mechanism 20 supports the gear 19 on the input shaft 18a of the reduction gear mechanism 18 mounted on the lower end of the rotary shaft 15 of the circular distribution board 11 of the tablet distribution means 10 and the powder distributor 6 of the powder dividing means 4. Holder 7
The gear 19 is engaged with the toothed belt 21, and the holder 7 is provided with a holder mounting seat at an appropriate position on the outer surface of the toothed belt 21 so that the and motors are driven simultaneously. Can be driven by. The speed reduction gear mechanism 18 is decelerated so that one pitch of the tablet distribution pockets 12 of the circular distribution board 11 corresponds to one pitch of the divided cells 6a of the powder dispenser 6. A stepping motor is used as the driving motor 22.

Although not shown, the motor 22 is supported by the frame of the main body 2, and the pinion 24 attached to the output shaft 22a of the motor 22 can be driven by meshing with the teeth of the toothed belt 21. A magnet holder 25 for adjusting the feed timing of the circular distributor 11 and the powder distributor 6 is attached to the output shaft 22a, and a timing sensor 26 is provided on the frame side so as to correspond to the magnet holder 25. ing.

On the other hand, in the powder dispenser 6, the holder 7 is made to traverse from the split position along the guide rails (not shown) to above the chute located above the split packaging unit 30 as in the conventional case. The valve plates are sequentially opened in order to discharge the divided powders one by one from the inside of the divided cells to the hopper via the chute. Therefore, stop sensors 27 and 27a are provided at the standby position of the powder distributor 6 (the position immediately below the powder receiving box 5) and the position most advanced for the division, respectively, thereby driving the powder. It is associated with a control unit (not shown) so that the motor 22 is stopped. The powder dispenser 6

And are detachably coupled by fasteners. Reference numeral 2 in the figure
8 is a tension gear.

The operation of the medicine packaging apparatus 1 of the present embodiment configured as described above is required in accordance with the prescription on the preset powder receiving box 5 when the powder is divided by the powder dividing means 4. When the powder is thrown in and leveled, and the opening / closing plate 5a is rotated to open, the powder is dropped onto the powder distributor 6 standing by at the position directly below and divided as in the conventional case. On the other hand, for tablets, required tablets (including capsules) are distributed and placed in the distribution pockets 12 of the circular distribution board 11 at the upper position of the main body 2.

When the division operation is completed in this way, the motor 22 is activated by turning on the activation switch, and the toothed belt 21 is driven. In this driving, the toothed belt 21 is rotated intermittently or continuously in accordance with an operating condition set in advance by a control device (not shown), and the powder is connected to the toothed belt 21 and positioned above the chute 8 above the packaging unit 30. Then, the valve plate is sequentially opened from the first divided box 6a, and the powder is dropped into the chute 8 one by one from the inside. The dropped powder is sent from the chute 8 through the hopper 31 of the wrapping section 30 into the inside of the wrapping paper 32a delivered from the paper roll 32, and is packaged and delivered by the heat seal device 33 one by one. The powder dispenser 6 is guided by a guide rail (not shown) and horizontally traverses to open the valve plate above the chute 8 and close the valve plate when returning.

On the other hand, on the tablet side, when the toothed belt 21 is driven by the drive of the motor 22, the gear 19 meshing with the toothed belt 21 moves the input shaft 18a of the reduction gear mechanism 18 to the circular distributor 11. When the circular distribution plate 11 is moved by one pitch of the tablet distribution pocket 12 after the rotation force is transmitted to the rotating shaft 15 by deceleration, the tablet is distributed from the tablet distribution pocket 12 corresponding to the drop opening 13a provided in the fixed face plate 13. The tablets are dropped onto the tablet chute 17 and supplied through the hopper 31 of the packaging unit 30 into the packaging paper 32a to be packaged. Thereafter, the circular distribution board 11 is rotated by the required number of sachets in this manner, whereby tablets are sequentially packed. It should be noted that when the circular distributor 11 makes one rotation, the distributor 6 of the powder agent is advanced so that the distributor 6 moves forward by the maximum stroke, so that the sensor 27a operates at the position where the distributor 6 is most advanced and the motor 22 of the motor 22 operates. Stop driving once. Therefore, the motor 2 is operated by the switch operation unit or by a preset control program.
When 2 is reversed, the distributor 6 is returned to the standby position, the motor 27 is stopped by the operation of the sensor 27, and the motor 22 is made to stand by until the start of the next packaging.

In the medicine packing apparatus 1 of the present embodiment, the powder distributor 5 and the tablet circular distributor 11 are simultaneously driven. Therefore, when only the powder is packed, the tablets are packed. By not performing the dispensing operation and conversely not performing the dividing operation of the powder when only tablets are packaged, the tablets can be separately packaged. Therefore, at the time of separately packing the powder and tablets, either one of the medicines may be distributed, and at this time, the other dividing means (dispensing means) is allowed to move. Further, in order to package the powder and the tablet at the same time, each of them is put into both of the dividing (distributing) means and the drive mechanism 20 is operated as described above.
It will be possible to package at the same time.

As described above, according to the present invention, the structure of the tablet dividing unit and the driving mechanism can be made reasonably compact, so that it is possible to downsize the entire apparatus, and a space for installation is required. The device can be placed in a dispensing room of a pharmacy and used effectively.
