As described in Japanese Patent Publication No. 20, a tablet feeder in which tablets are continuously discharged one by one from a single outlet, and a tablet feeder capable of selectively discharging tablets from a plurality of outlets is still not available. unknown. For this reason, it has not been possible to form a tablet packaging device having a large processing capacity having a plurality of packaging devices.

[0008] The utility model application publication No. 39 of 1939
In Japanese Patent Publication No. 6 (1999), there is described a tablet fixed-quantity take-out device capable of taking out a plurality of tablets by a slide of a take-out plate. However, since a plurality of tablets are taken out at the same time, tablets are packed for each dose. And cannot be selectively supplied to a plurality of packaging devices. For this reason, in this case as well, a tablet packaging device having a large processing capacity cannot be formed as described above.

In view of the above, the present invention provides a tablet feeder having a plurality of discharge paths and capable of selectively discharging tablets from the discharge paths, thereby enabling a tablet packaging apparatus having a large processing capacity to be formed. It is a technical issue.

[0010]

In order to solve the above problems, the present invention forms a plurality of rotor storage recesses at the bottom of a tablet storage case provided on a support table and incorporates the rotor storage recesses into each of the rotor storage recesses. A plurality of pockets are provided at required intervals on the outer periphery of the rotor rotated by the motor supported by the support base, and an outlet facing one of the pockets is formed on the peripheral wall of each rotor storage recess; The support base had a configuration in which a discharge path was provided in communication with each outlet.

[0011]

In the tablet feeder having the above-described structure, one or a plurality of rotors are selected from a plurality of rotors and rotated, and the tablets that have entered the pockets of the rotors are discharged from the outlet to the discharge path.

Therefore, the tablet storage case 2 can be detached from the support table 1 by sliding the tablet storage case 2 along the guide groove 3.

The tablet storage case 2 has an openable and closable lid 5 at an upper portion, and the tablets are filled in the tablet storage case 2 by opening the lid 5.

At the bottom of the tablet storage case 1, conical first rotor storage recesses 6a and second rotor storage recesses 6b are formed.
Is provided. A first rotor 7a and a second rotor 7b are incorporated in each of the rotor housing recesses 6a, 6b.

The first rotor 7a and the second rotor 7b are provided with a conical outer surface 8, and a plurality of pockets 9 are formed at equal intervals in a circumferential direction of the conical outer surface 8. The pocket 9 opens at the upper end surfaces of the rotors 7a and 7b. The pocket 9 has a length capable of accommodating two tablets a, but may have a length accommodating one tablet a.

The rotors 7a and 7b are driven to rotate by motors 10a and 10b supported on the support base 1.
Here, the motors 10a and 10b may rotate the rotors 7a and 7b at a constant speed.
May be intermittently rotated with the pitch of the rotation angle as a rotation angle.

On the peripheral walls of the first rotor housing recess 6a and the second rotor housing recess 6b, tablet outlets 11a and 11b are provided so as to face one of the pockets 9.
A tongue piece 12 is attached to the upper part of 1a, 11b. The tip of the tongue piece 12 penetrates into a circumferential groove 13 formed in the conical outer surface 8 of the first rotor 7a and the second rotor 7b, and the tablet a in the pocket 9 is inserted into the tablet outlets 11a and 11b.
When discharged from the pill, the tablet is prevented from being continuously discharged.

The support 1 is provided with the above-mentioned tablet outlets 11a, 11
b, a first discharge path 14a and a second discharge path 14b are provided. Each discharge path 14a, 14b
Is provided with a detection sensor (PH) for detecting the passage of the tablet, and the motors 10a and 10b are controlled based on a detection signal of the detection sensor (PH).

The tablet feeder shown in the embodiment has the above-described structure. For example, when the first motor 7a and the second rotor 7b are rotated by the motors 10a and 10b, the tablet intrudes into the pockets 9 of the rotors 7a and 7b. a is a first discharge path 1 communicating with the tablet outlets 11a and 11b at a position facing the tablet outlets 11a and 11b.
