Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an automatic drug packaging machine that automatically packages tablets and powders in predetermined amounts.

[Prior Art] In this type of conventional technology, a movable body in which a large number of tablet dispensing chambers and a large number of powder dispensing chambers are arranged in a linear manner is slid in one direction, and along with this, a moving body is moved in one direction. There was one in which tablets and powders were dropped one after another and separated into packages.

However, such conventional devices require a stroke to slide the movable body, which increases the size, and once the movable body has finished moving in one direction, it must be moved in the opposite direction to its original position. Moreover, since tablets and powders must be supplied to each dispensing chamber at the original location, there are problems such as having to interrupt the dispensing operation during this time. Therefore, in order to improve the efficiency of the dispensing process of tablets and powders, for example, a double annular rotating body with tablet dispensing holes or powder distributing holes arranged annularly on the inside and outside is provided, and each of the annular rotating bodies is A device in which rotational movement is performed independently has also been proposed (Japanese Patent Laid-Open No. 56-64901).

[Problems to be Solved by the Invention] However, since the above-mentioned conventional system only includes one double annular rotating body,
The processing capacity for dividing and packaging tablets and powders is small, and it is difficult to automatically package individual tablets and powders, mixed packaging, alternating packaging, etc. without interruption. Moreover, when two such packaging devices are installed in parallel, there is a disadvantage that a large amount of plane space is taken up in the hospital pharmacy, and furthermore, there is a disadvantage that the dispensing work becomes complicated. The object of the present invention is to provide an automatic drug packaging machine which eliminates the drawbacks of the conventional ones and is capable of automatically and continuously carrying out single packaging, mixed packaging, alternate packaging, etc. of each of tablets and powders without interruption. The purpose is to

[Means for Solving the Problems] In order to achieve the above object, the present invention includes at least one powder feeder, which is arranged inside and outside of each other, and each discharges tablets selectively fed from the tablet feeder. a first double annular rotary body having a plurality of tablet dispensing chambers that can accommodate a plurality of tablet dispensing chambers; a second double annular rotating body having a powder dispensing chamber; A common hopper for receiving tablets and powders discharged from both double annular rotors at the lower part of the two double annular rotors, a packaging device for packaging these medicines, and a hopper inside and outside of each of the double annular rotors. and a drive device that selectively rotates one of the tablet feeder or the powder feeder in accordance with the feeding speed of the tablet feeder or the powder feeder, and rotates the other in accordance with the packaging speed of the packaging device. shall be.

A plurality of vertical drawers 22, 22..., which are provided in a case 21 with an open front so that they can be pulled out, are arranged in parallel on shelves 23, 23..., which are stacked vertically, respectively. When receiving a discharge signal from the device 20, the tablets are discharged one by one through a duct (not shown) provided behind each shelf 23 (on either the left or right side when viewed from the front of the case 21) and passing through between the top and bottom. It is designed to make you fall.

Powder feeder Powder feeders 8 and 8' have the same structure, and have a hopper 2 at the top, as shown in Figure 4.
A conical body 26 whose top protrudes upward while maintaining a required gap with the drop hole of the hopper 24 is provided in a case 25 having a cone body 4. The conical body 26 has an annular groove 27 with an arcuate cross section formed on its lower periphery, and when the powder is introduced into the hopper 24, it is rotated by the drive of the motor 28 and falls through the gap between the drop hole of the hopper 24. The powder is distributed almost evenly in the circumferential direction and accommodated in the annular groove 27. A scraping member 32 is provided inside the case 25 and is formed by combining a disc 29 and a semicircular plate 30 that fit into the annular groove 27 with a scraping plate 31, and the scraping member 32 is at the scraping position shown in the figure. It can be displaced between this position and the position where it has been retracted upward. When the powder is introduced into the hopper 24, it is in the retracted position so as not to disturb the even distribution of the powder due to the rotation of the cone 26, and then it is displaced to the scraping position and rotated by the drive of the motor 32, so that the cone 26 rotates. Accordingly, the powder in the annular groove 27 is scraped out in fixed amounts and discharged. The powder discharged from the powder feeder 8 is supplied to the powder distribution chambers 11, 11... through the shutter 34, and the powder discharged from the powder feeder 8' passes through the shutter 34' to the powder distribution chambers 12, 12...

11..., the bottom plates of which are sequentially opened on the hopper 13 to allow the powder to fall. In this case, if only the former is done, tablets will be packaged continuously, if only the latter is done, powders will be packaged continuously, and if the former and latter are done simultaneously, tablets and powders will be packaged. If the former and the latter are carried out alternately, tablets and powders will be packaged alternately.

Furthermore, during the packaging operation by the annular rotating bodies 2 and 9, the annular rotating bodies 3 and 10 can receive tablets and powders from the tablet feeder 1 and the powder feeder 8', respectively, and During the packaging operation by 3 and 10, the annular rotating bodies 2 and 9 receive tablets and powders from the tablet feeder 1 and the powder feeder 8, respectively.

Therefore, if a dispensing worker such as a pharmacist only performs the necessary dispensing work on the powder (i.e., taking it out of the device bottle, weighing it, mixing it, etc.) and putting it into the powder feeders 8, 8', Everything else is processed automatically so that the necessary sachets can be obtained continuously without interruption.

In the above embodiment, the tablet feeders 1, 1... are stacked on the pull-out storage shelves 23, 23..., which is preferable in terms of space, but the invention is not limited to this. Powder feeders 8 and 8' are preferable because they can distribute and feed powder at a much higher speed than conventional general vibrating feeders, but they are not limited to such feeders, and the number of feeders is limited to two. Not exclusively. In addition, a number of suitable transport containers are provided to temporarily store powders that have been subjected to necessary dispensing operations such as removal from equipment bottles, weighing, and mixing, and these transport containers are placed directly above the powder feeder 8 or 8'. After all the powders in the powder feeder 8 or 8' have been discharged and necessary dust has been removed, the powders in the transport container may be dropped. The dispensing operator can carry out the dispensing work of powder one after another regardless of the state of discharging the powder from the powder feeder 8 or 8', which is preferable in terms of efficiency improvement.
