It is configured to rotate by 80 degrees and stop, so that the insertion hole 55a of the separating means 55 is provided so as to be movable between the accommodation cylinder 54 and the insertion cylinder 53.

The separating means 55 includes a supply port 6 of the containing cylinder 54.
A shielding portion 55b for sealing 2 and a shielding surface 55c are formed around the charging hole 55a, and the solid tablet G3 is inserted into the charging hole 55a by its own weight before the tablet charging. In this state,
When the separating means 55 is moved toward the charging cylinder 53, only the solid tablet G3 inserted into the charging hole 55a is conveyed by the shielding surface 55c of the separating means 55, and the next solid tablet G3.
Is not supplied from the supply port 62 of the housing cylinder 54.

Then, the separating means 55 conveys the solid tablets G3 to the position of the feeding cylinder 53, and when the state shown in FIG. 21 is reached, the solid tablets G3 are dropped by dropping naturally from the charging port 53a of the charging barrel 53.

In this way, when the solid tablets G3 are charged and the separating means 55 is moved by the 180 degree rotation of the motor 60 to the position shown in FIG.
The lowermost solid tablet G3 stacked on top is the shielding surface 5.
The solid tablet G3 is inserted into the charging hole 55a by its own weight by 5c and is ready for the next charging of the solid tablet. This separating means 55
The height H1 of the charging hole 55a defines the minimum thickness of the solid tablet, and the height H2 of the separating means 55 defines the maximum thickness of the solid tablet. The solid tablet having the thickness in this range can be freely set. Can be thrown.

23 to 24 show an embodiment of a tablet loading apparatus of a type in which solid tablets are stacked and fed laterally and loaded downward. FIG. 23 is a sectional view of the tablet loading apparatus, and FIG. 24 is a bottom surface of the tablet loading apparatus. It is a figure.

In this tablet loading device, a support plate 71 is attached to a column 70 with bolts 72, and a cover 73 is attached to the lower side of the support plate 71 with screws 74. The closing cylinder 40 is press-fitted into the cover 73, and the separating means 26 is rotatably supported in the cover 73 by a mounting screw 27. The separating means 26 has the same structure as that of the embodiment shown in FIGS. 12 to 19, but a gear 26g is formed around the separating means 26, and the gear 26g is formed.
The gear 76 a of the speed reduction mechanism 76 meshes with the gear 76 b, and the gear 76 b meshes with the gear 79 fixed to the output shaft 78 of the motor 77.

Accordingly, the driving of the motor 77 causes the separating means 26 to rotate via the speed reducing mechanism 76, and the solid tablets G from the housing cylinder 80 attached to the upper side of the support plate 71.
When 1 is put in one, when the separating means 26 is rotated once, the shielding part 26b of the separating means 26 is disengaged from the carry-in port 22 and is continuous with this shielding part 26b and receives the solid tablets at the shielding surface 26c and is rotationally conveyed. To do. And further separating means 2
When 6 rotates, the solid tablet enters the charging hole 26f continuous with the shielding surface 26c, and the solid tablet passes through the passage 4 of the charging cylinder 40.
0a, the solid tablet is guided to a position facing the charging port 25, drops from the charging port 25, is guided by the guide 41, and is charged.

By providing a receiving portion (bottom portion) for the solid tablets in the carrying section, it is possible to similarly carry the solid tablets in a desired direction. As a force for pushing the solid tablet, a spiral wound spring may be used in the figure, but the present invention is not limited to this, and various known structures such as a rack and pinion feed screw feed can be used.

The force for pushing the solid tablets is not required when the spring is used, but in the case of the rack and pinion feed screw feed, it is necessary to detect the position and operate it by using a well-known sensor, micro switch or the like. From the force to push out the solid tablets,
Energize the force that strongly presses the transport surface that receives it,
Use a structure that does not allow moisture to enter.
