It is supported and rotated integrally with the main shaft 16, and a support 37 for fixing the auxiliary shaft 25 is provided on the upper surface of the lower plate 35B.

In addition, the vertical axis of the upper and lower plates 35A, 35B is vertically transversely positioned so that the inner shaft 16A of the main shaft 16 is located, and the vertical bevel gear 15A mounted on the inner shaft 16A at this time. It is located in between. In addition, the upper and lower plates 35A and 35B are equipped with four pairs of guide bushes 38 each having two pairs, and the two upper and lower guide bushes 38 of each pair have the same central longitudinal axis (eg, the above-mentioned). The center axis of the injector 23). These four pairs of guide bushes 38 maintain 90 ° intervals from each other, such as the installation position of each injector 23.

In addition, the injector 23 is inserted one by one for each of the four guide bushing mounting position, wherein the body is vertically across the upper and lower guide bushes 38, and is mounted at the lower end thereof. The injection hole 39 is installed to be located outside the bottom of the lower plate 35B, so that the up and down movement can be guided. In particular, one side of the body of the injector 23 is equipped with a bearing pin (34B) in contact with the cam 24 of the auxiliary shaft 25 to be described later, the bearing pin (34B) in this direction perpendicular to the injector body It is free to rotate while having the center of the axis of the axis, while sliding along the outer periphery of the cam 24 to mediate the vertical movement of the injector (23). In addition, the injection hole 39 has a filter 53 built therein, and the amount of powdered medicine sucked into the injection hole 39 can be adjusted according to its up and down position.

The cam 24 is attached to the outside of 15B. At this time, the horizontal bevel gear 15B mounted on the inner end of the auxiliary shaft 25 is interlocked with and interlocked with the vertical bevel gear 15A on the inner shaft 16A positioned at the inner center of the rotary support plate 35. , The cam 24 mounted on the outer leading end portion of the auxiliary shaft 25 is connected to the bearing pin 34B on the injector 23 positioned at the inner outer side of the rotary support plate 35. do. The auxiliary shaft 25 installed as described above is installed between the one inner shaft 16A and the four injectors 23 to have a radial installation structure. In particular, the cams 24 mounted on the two auxiliary shafts 25 facing each other are mounted so that the noses of each other, which means the tip protrusions, face in the same direction, and are installed in the cross symmetrical position. Each cam 24 attached to the remaining two auxiliary shafts 25 is also mounted such that the noses of each other face the same direction as the above-described 24 cams 24 while having the same direction. That is, the four cams 24 described above are mounted in the same direction. That is, when the powdered medicine storage tank 22 and the injector 23 positioned at the top of the container are lowered to the downward limit position, the noses of the respective cams 24 connected thereto are also directed downwards, and thus, the remaining two The nose of the cam 24 also faces downward. Accordingly, the motion traces formed by the four injectors 23 are represented by the continuous pulse wave form by the respective cam diagrams.

In addition, on the upper support plate 32 of the other side where the supply and take-out of the container is made, a chemical storage tank 22 supported by two or four posts 40 is provided. Continuous drug supply is made from an external drug supplier (not shown), so that a certain level of drug is always filled regardless of the amount of drug that is drawn out through the injector 23.

In addition, inside the drug storage tank 22, there is located a rotating plate 29 of the stirring device 21, which serves to stir the drug so that the drug filled in the tank is not biased in any particular part. Rotating plate 29 is rotated integrally with the rotary shaft 30 is supported on the upper support plate 32 while extending vertically downward, the rotation operation of the power shaft 14 and the electric pulley (30) between the rotary shaft (30) By belt transmission through 12). Here, although the power shaft 14 and the rotation shaft 30 have a rotation ratio of about 1: 1, it is preferable to configure the rotation speed of the rotation shaft 30 to be somewhat higher than the rotation speed of the power shaft 14.

In addition, the vacuum pressure distributor 26 is installed while wrapping the housing 31 supporting the inner shaft 16A of the main shaft 16 at the center of the upper plate 35A of the rotary support plate 35, The vacuum pressure divider 26 is connected to the vacuum pump device, the nitrogen gas supply device (not shown), and the inlet port 23 of the injector 23, respectively, via a tube, so as to supply nitrogen gas supplied from the nitrogen gas supply device. It acts as an intermediate medium so that it selectively sends to each injector 23 and the vacuum pressure generated in the vacuum pump device acts on the inlet 39, and at the same time, the vacuum pressure is sequentially applied to each inlet 39. It will act as a crackdown to help.

Looking at the operation of the pharmaceutical powder filling apparatus according to the present invention configured as described above are as follows.

First, it is assumed that the injector 23 of the drug storage tank 22 is continuously supplied with drugs and containers from an external drug supply device and an external alignment device.

When the power shaft 14 is rotated in one direction, for example, counterclockwise by the operation of the drive motor 11, the stirring device 21 through the first electric pulley 12A and the second electric pulley 12B. Rotation shaft 30, the inner shaft 16A through the third electric gear (10C) and the fourth electric gear (10D), the outer shaft 16B through the partition plate 13 and the Geneva gear 17 is rotated at the same time. . At this time, when the divider plate 13 rotates once, the Geneva gear 17 rotates 1/4, so that the outer shaft 16B rotates only 1/4 of the rotation of the power shaft 14. As such, when the outer shaft 16B is rotated quarterly, the entire rotary support plate 35 interlocked therewith is rotated quarterly so that each injector 23 is moved by a distance corresponding to 90 °. In addition, the driven shaft through the interlocking movement of the fifth electric gear (10E), the sixth electric gear (10F), the seventh electric gear (10G) and the eighth electric gear (10H) by the rotation of the outer shaft (16B). 20 is rotated a quarter so that each container seating groove 36 of the container transfer plate 19 at this time is also moved by a distance corresponding to 90 °. That is, according to the quarter turn of the container transfer plate 19, the empty container is transferred from the external alignment device to the filling position and the container filled with the medicine is transferred to the discharge position for transfer to the next process.

At the same time, the inner shaft 16A rotated with the same rotation ratio as the power shaft 14 is rotated one by one rotation of the power shaft 14, and the vertical bevel gear 15A rotates integrally therewith. ) And the four horizontal bevel gears 15B interlocked with each other are rotated together. Accordingly, the vertical movement of the injector 23 is made by the rotational movement of each cam 24 of the auxiliary shaft 25. You lose.

That is, each injector 23 located in the upper portion of the drug storage tank 22 and the upper portion of the empty container conveyed by the container transfer plate 19 is lowered to the downward limit position to perform the function, The other two injectors 23 which are in a symmetrical relationship are lowered to the downward limit position similarly to the two injectors 23 described above. In particular, the injector 23 in which the medicine is inhaled by the vacuum pressure from the medicine storage tank 22, the injector 23 immediately before filling the container with the medicine, and the injector 23 positioned therebetween are always filled with vacuum. Pneumatic pressure is acting (for example, the recess 47 formed in the lower fixing plate 42 of the vacuum pressure divider 26, each vacuum pressure injection hole 48 corresponding to each injector 23 described above) At the same time, when the injector 23 descends and the inlet 39 of the tip reaches the maximum distance from the neck of the container, the drug is released by the pressure of nitrogen gas with the release of the vacuum pressure that has been operated up to this time. As it falls, it fills the container. Since the filling operation should be performed while the injector 23 and the container are continuously rotating and being transported, the instant filling operation is performed at a position where the rotational trajectory of the injector 23 and the transport path of the container coincide with each other. .

Therefore, the injection port 39 of the injector 23 and the neck of the container are located at the closest distance at the moment when the medicine and the filling of the container are made.

In this case, when the inner shaft 16A of the main shaft 16 is rotated one time, that is, when the inner shaft 16A of the main shaft 16 and the auxiliary shaft 25 are rotated one time, the vertical movement of the injector 23 is performed by one quarter rotation. Referring to the linking operation process, the vertically transmitted to the inner shaft 16A through the first electric gear 10A, the second electric gear 10B, the third electric gear 10C, and the fourth electric gear 10D in this order. The type bevel gear 15A has 40 teeth, and the horizontal bevel gear 15B fitted thereto has 30 teeth (for example, a gear ratio of the vertical bevel gear 15A and the horizontal bevel gear 15B). Is composed of 4: 3) The 40-number of vertical bevel gears 15A are vibrated and engaged, and thus, when the vertical bevel gear 15A is rotated once, the horizontal bevel gears 15B are 1 and. It will rotate 1/3. However, when the driving pin split plate 13 rotates once from the first electric gear 10A to the power shaft 14, the Geneva gear 17 at this time makes 1/4 rotation corresponding to about 90 °. The outer shaft 16B of the main shaft 16 transmitted from the Geneva gear 17 and the rotation support plate 35 rotated integrally therewith also rotate 90 °, and the horizontal bevel gear 15B mounted thereon is vertically mounted. It rotates 1/3 by 10 teeth in the direction opposite to the transmission direction by the type bevel gear 15A.

Therefore, the same effect as the result of the vertical bevel gear (15A) is rotated 1/4 in reverse by a relative number of 10 teeth. When the vertical bevel gear 15A rotates as described above, the horizontal bevel gear 15B also rotates once, and as a result, an accurate up and down movement of the injector 23 is achieved.

Therefore, the vertical bevel gear 15A and the horizontal bevel gear 15B are rotated in the same number of teeth but different from each other by 40 teeth and 30 teeth, and thus the second electric gear 10B from the first electric gear 10A. ), The third electric gear 10C, the fourth electric gear 10D, the inner shaft 16A, the vertical bevel gear 15A, and the rotation by the vertical bevel gear 15A connected by the horizontal bevel gear 15B. Reverse rotation intermittent rotating device by the device and Geneva gear 17 connected from the first electric gear 10A to the divider plate 13, the Geneva gear 17, the rotation support plate 35, and the horizontal bevel gear 15B. It can be said that the combination is the most characteristic part constituting the pharmaceutical powder filling apparatus of the present invention.

As described above, the present invention has the advantage of obtaining a non-polluted homogeneous product and the effect of improving work productivity by making the filling operation of the pharmaceutical powder into a continuous operation by automation.
