[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tablet feeder for quantitatively supplying tablets (including capsules).

[0002]

[Prior Art]

 2. Description of the Related Art As a tablet packing device for packing tablets, the one described in Japanese Utility Model Laid-Open No. 62-76102 is conventionally known.

The above-mentioned tablet packing apparatus has a large number of tablet feeders, and a controller selects and operates one tablet feeder, and the tablets discharged from the tablet feeder are introduced into a common hopper from a drop guide path. It is dropped and supplied to the packing device from the lower end outlet of the hopper for packing.

By the way, in the above-mentioned tablet packaging apparatus, since the packaging processing is performed for each prescription, the processing capacity is low, and there is a problem that a pharmacy of a large hospital with a large number of patients cannot sufficiently cope with it.

Therefore, if a plurality of packaging devices of the tablet packaging device are provided so that the tablets discharged from each tablet feeder can be selectively supplied to each of the packaging devices, each packaging device can be used. The applicant of the present invention has found that since different types of tablets can be packaged at the same time, a large effect can be obtained in improving the processing capacity.

[0006] In order to form the tablet packaging device as described above, a tablet feeder capable of selectively supplying tablets to each packaging device is required.

[0007]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention By the way, a conventionally known tablet feeder is of a type in which tablets are continuously discharged one by one from a single outlet, and tablets are discharged from a plurality of outlets. A tablet feeder capable of being selectively discharged is not yet known. For this reason, it was not possible to form a tablet packaging device having a plurality of packaging devices and a large processing capacity.

Therefore, the present invention provides a tablet feeder having a plurality of discharge passages and capable of selectively discharging tablets from the discharge passages, and enables the formation of a tablet packaging device having a large processing capacity. This is a technical issue.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, a rotor is rotatably incorporated in the bottom of a tablet storage case provided on a support base, and a motor for driving the rotation of the rotor is supported by the support base. In a tablet feeder in which a plurality of pockets are provided on the outer periphery of the rotor at a required interval, an outlet is formed in the lower part of the tablet storage case so as to face one of the pockets, and the tablet is discharged from the outlet. The support base is provided with an inlet passage communicating with the outlet and a plurality of discharge passages below the inlet passage, and the tablets discharged from the inlet passage are guided to one of the discharge passages between the inlet passage and the discharge passages. The changeover damper is installed so that it can swing freely.

[0010]

[Action]

 The tablet feeder having the above structure rotates the rotor by driving the motor, discharges the tablets that have entered the pocket of the rotor from the outlet to the inlet passage, and guides them to any one of the discharge passages by the switching damper. Discharge.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 and 2, the tablet feeder according to the present invention comprises a support base 1 and a tablet storage case 2 provided on the support base 1, and the tablet storage case 2 is a lid 3 which can be opened and closed. Is provided at the upper part, and the tablet 3 is filled with tablets by opening the lid 3.

A bottom surface 4 of the tablet storage case 2 has a conical shape, and a rotor 5 is provided on the bottom surface 4. A conical outer surface 6 is formed on the rotor 5, and a plurality of pockets 7 are provided at equal intervals in the circumferential direction of the conical outer surface 6.

The pocket 7 is open at the upper end surface of the rotor 5. The pocket 7 has a length capable of accommodating two tablets a, but may have a length capable of accommodating one tablet.

The rotor 5 is rotated by a motor 8 incorporated in the support base 1. Here, the motor 8 may rotate the rotor 5 at a constant speed or intermittently rotate the pitch of the pocket 7 as a rotation angle.

A tablet outlet 9 is provided in a lower portion of the tablet storage case 2, and a tip end portion of a tongue piece 10 provided in an upper portion of the tablet outlet 9 has a circumferential direction formed on a conical outer surface 6 of the rotor 5. When the tablets having entered the groove 11 and discharged from the pocket 7 are discharged from the outlet 9, the tablets are prevented from being continuously discharged.

The support base 1 is provided with an inlet passage 12 at a position facing the outlet 9. The inlet passage 12 is inclined, and a first discharge passage 13a and a second discharge passage 13b are branched at its lower end.

A switching damper 14 is provided at a branch portion between the first discharge passage 13 a and the second discharge passage 13 b and the inlet passage 12. The switching damper 14 is swung about a shaft 16 by a driving device 15 such as a rotary solenoid. The rocking causes the inlet passage 12 to communicate with the first discharge passage 13a or the inlet passage 12 to communicate with the second discharge passage 13b.

Reference numeral 17 in the drawing denotes a tablet detection sensor discharged from the inlet passage 12, and the motor 8 is controlled based on a detection signal of the detection sensor 17.

The tablet feeder shown in the embodiment has the above structure, and FIG. 2 shows a state in which the inlet passage 12 and the first discharge passage 13a are in communication with each other. In this state, when the motor 8 is driven and the rotor 5 is rotated, the tablet a that has entered the pocket 7 of the rotor 5 is discharged from the outlet 9 to the inlet passage 12 at a position facing the outlet 9, It is discharged from the first discharge passage 13a.

When switching the tablet discharging direction, the switching damper 14 is swung by the operation of the driving device 15 so that the second discharging passage 13 b communicates with the inlet passage 12. By switching the damper 14, the tablets discharged from the outlet 9 to the inlet passage 12 are discharged from the second discharging passage 13b.

FIG. 3 shows another embodiment of the tablet feeder according to the present invention. In this embodiment, a first discharge passage 13a, a second discharge passage 13b, and a third discharge passage 13c are provided below the inlet passage 12, and a switching damper 14 provided on the outlet side of the inlet passage 12 has a cylindrical shape. The switching damper 14 is swung about a shaft 16 by a driving device 15 such as a rotary solenoid.

In this embodiment, the drive device 15 is operated to swing the switching damper 14 so that the switching damper 14 is communicated with any one of the first discharge passage 13a to the third discharge passage 13c, and the outlet is provided. The tablets discharged from 9 to the inlet passage 12 are guided by the switching damper 14 and discharged to the discharging passage communicating with the damper 14.

[0023]

[Effect of the device]

 As described above, in the tablet feeder according to the present invention, since the tablets can be discharged from any one of the plurality of discharge passages by switching the switching damper, a large number of tablet feeders are prepared, Simultaneous packaging of different types of tablets by each tablet packaging device is provided by providing guide means for guiding tablets discharged from each of the tablet feeder's ejection passages to the same number of tablet packaging devices as the ejection passages. Therefore, it is possible to form a tablet packaging device having a large throughput.
