Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tablet feeder for quantitatively supplying tablets (including capsules).

[0002]

2. Description of the Related Art As a tablet packing apparatus for packing tablets in tablets, the one disclosed 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 the tablets continuously discharged from one tablet feeder are dropped from a drop guide path into a common hopper, and are packed from the lower end outlet of the hopper. It is supplied to the device and packaged.

By the way, in the above tablet packing apparatus,
Since it is a packaging process for each prescription, there is a problem that the processing capacity is low and it cannot be adequately handled by a pharmacy of a large hospital with a large number of patients.

Therefore, a plurality of packing devices of the tablet packaging device are provided, and tablets are selectively supplied from each tablet feeder to each of the packing devices, or one tablet feeder supplies tablets to each of the packing devices. The applicant of the present invention has found that, if it is obtained, different kinds of tablets or the same kind of tablets can be simultaneously packaged in each packaging apparatus, so that the processing ability is greatly improved.

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

[0007]

By the way, the conventionally known tablet feeder is of a type in which tablets are continuously discharged one by one from a single tablet outlet, and tablets are discharged from a plurality of outlets. A tablet feeder capable of being selectively discharged has not yet been known. Therefore, it was not possible to form a tablet packaging device having a plurality of packaging devices and a large processing capacity.

Under the above circumstances, it is a technical object of the present invention to provide a tablet feeder capable of selectively discharging tablets from a plurality of outlets or discharging tablets from each of the outlets. .

[0009]

In order to solve the above-mentioned problems, according to the present invention, a rotor is rotatably incorporated into the bottom of a tablet storage case provided on a support base, and a motor for rotating the rotor is used. Is supported by the support base, a plurality of pockets are provided on the outer periphery of the rotor at a required interval, and a plurality of outlets are formed at the lower part of the tablet storage case at positions facing the pockets, and each outlet is opened and closed. Provide a free gate,
The support base has a structure in which a discharge path is provided at a position facing each outlet.

[0010]

In the tablet feeder having the above structure, when the tablets are discharged from the respective tablet discharge paths, the gates provided at the respective outlets are opened, the motor is driven, and the rotor is rotated. The tablets that enter the pocket due to the rotation of the rotor are discharged from the outlet to a discharge passage communicating with the outlet at a position facing the outlet.

[0011]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 and 2, the tablet feeder includes a support base 1 and a tablet storage case 2 provided on the support base 1. In the embodiment, a pair of guide grooves 3 are formed on both sides of the upper surface of the support base 1, while the tablet storage case 2 is provided with a projecting portion 4 which is slidable along the guide groove 3 to attach and detach the tablet storage case 2. Supports freely.

The tablet storage case 2 has an openable / closable lid 5 in the upper part, and when the lid 5 is opened, tablets are filled in the tablet storage case 2.

The bottom surface 6 of the tablet storage case 2 has a conical shape, and the rotor 7 is provided on the bottom surface 6. A conical outer surface 8 is formed on the rotor 7, and a plurality of pockets 9 are provided at equal intervals in the circumferential direction of the conical outer surface 8.

The pocket 9 is open at the upper end surface of the rotor 7. The pocket 9 has a length capable of accommodating two tablets a, but may have a length capable of accommodating one tablet.

The rotor 7 is rotated by a motor 10 supported by the support 1. Here, the motor 10 may rotate the rotor 7 at a constant speed, or may intermittently rotate the pitch of the pocket 9 as a rotation angle.

At the bottom of the tablet case 2, there is a first outlet 1
1a and a second outlet 11b are provided, and each outlet 11a,
The tongue piece 12 provided on the upper portion of 11b is such that when the tip portion of the tongue piece 12 enters the circumferential groove 13 formed on the conical outer surface 8 of the rotor 7 and the tablet a in the pocket 9 is discharged from the outlets 11a and 11b. , Tablet a is prevented from being continuously discharged.

The first outlet 11a and the second outlet 11b
1 is provided with a first gate 14a and a second gate 14b, and the gates 14a and 14b are opened and closed by a driving device 15 such as a solenoid shown in FIG.

The support 1 has a first outlet 11a and a second outlet 11a.
A first discharge passage 16 and a second discharge passage 16b are provided so as to communicate with the outlet 11b.

Reference numeral 17 shown in FIG. 2 indicates a sensor for detecting the tablets discharged to the first discharge passage 16a and the second discharge passage 16b.

The tablet feeder shown in the embodiment has the above structure. For example, when the motor 10 is driven and the rotor 7 is rotated with the first gate 14a and the second gate 14b opened, the rotor 7 is rotated. Tablets stored in the pocket 9 of the first outlet 11a and the second outlet 11
It is discharged from each of the outlets 11a and 11b at a position facing b, and is discharged from each of the first discharge passage 16a and the second discharge passage 16b.

When the rotor 7 is rotating, the first
One of the gate 14a and the second gate 14b, for example,
When the first gate 14a is closed, the ejection of tablets from the first outlet 11a is stopped, and the tablets are ejected only from the second outlet 11b. Then, when each of the first gate 14a and the second gate 14b is closed, the tablet will be in any outlet 11
The tablets a and 11b are not discharged, and the tablet discharging operation is stopped.

As described above, the tablet feeder can selectively discharge tablets from the first outlet 11a and the second outlet 11b, or can simultaneously discharge tablets from both outlets. By providing guide means for individually guiding the tablets discharged from the discharge passage of each feeder to the same number of tablet packaging devices as the discharge passages of one tablet feeder, each of the tablet packaging devices can be provided. The simultaneous packaging of different types of tablets and the simultaneous packaging of the same type of tablets are possible, and a tablet packaging apparatus having a large packaging capacity can be formed.

Although the tablet storage case 2 is provided with the first outlet 11a and the second outlet 11b in the embodiment, the number of outlets is not limited to this, and may be two or more.

[0024]

As described above, according to the tablet feeder of the present invention, the tablet storage case is provided with a plurality of outlets that can be opened and closed by the gate, and the outlets are connected to the outlets. The tablet can be discharged more, and the tablet can be selectively discharged to any one of the plurality of discharge paths.
