Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic view of a medicine packaging apparatus according to the present invention. This medicine packaging apparatus has a medicine storage 1 in which a large number of tablet feeders 2 are stored.

FIG. 2 shows an example of the tablet feeder 2. The tablet feeder 2 has a rotor 4 incorporated in the bottom of the tablet storage case 3 and a plurality of pockets 5 on the outer periphery of the rotor 4.
Are provided at regular intervals, and the rotor 4 is intermittently rotated by the motor 6 at an angle corresponding to the pitch at which the pockets 5 are formed. It is made to be discharged one by one.

Here, the tablet feeder 2 is provided with a plurality of outlets. In the embodiment, the first outlet 7a and the second outlet 7b are formed at an interval of 180 °, and each outlet 7a, 7
A gate 8 is provided at b, and the gate 8 is opened and closed by a solenoid 9.

A chute 10 is connected to each of the first outlet 7a and the second outlet 7b, and the chute 10 is provided with a sensor PH for detecting the passage of tablets. The detection signal of the sensor PH is input to the control device 11 shown in FIG. 1 and counted. The control device 11 checks the detection signal from the sensor PH with data input in advance, and stops the motor 6 when the number of tablets detected by the sensor PH matches the data.

The control device 11 controls the motor 6 of the tablet feeder and the solenoid 9 for opening and closing the gate based on the data input to the input unit 12.

The arrangement of the tablet feeder 2 is optional.
As shown in FIG. 1, a plurality of tablet feeders 2 arranged in the vertical direction may be provided in multiple rows on the left and right, or a plurality of tablet feeders 2 arranged in the front and rear direction may be provided in multiple stages in the vertical direction, and It may be provided in multiple rows.

A plurality of tablet feeders 2 arranged at equal intervals in the circumferential direction may be provided in multiple stages in the vertical direction.

The two outlets 7a, 7b of each tablet feeder 2
Of the two chutes 10 connected to the first outlet 7a
Is connected to the first drop guide path 13a, and the chute 10 connected to the second outlet 7b is connected to the second
It is connected to the fall guide path 13b.

Below the first drop guide path 13a and the second drop guide path 13b, hoppers 14a and 14b are provided, respectively. Below the hoppers 14a and 14b, a first packing device 15a and a second packing device 15b are provided. Is provided.

FIG. 3 shows an example of the packaging devices 15a and 15b. This packaging device includes a triangular former 16 for folding the heat-fusible wrapping sheet S drawn out from the roll R into two in the width direction, and a wrapping sheet S folded in two in the width direction. A horizontal heating roller 17 that heat seals in a streak shape over the entire direction and a vertical heating roller 18 that heat seals both side edges of the folded packaging sheet S continuously in a streak shape are sequentially provided. The hopper 14a or 14b is placed on the bag a
Is arranged.

The packaging devices 15a and 15b are
The tablets falling into the bag a from the lower end outlets of the a and 14b are moved together with the sheet S, and the horizontal heating roller 17
The tablet is packaged for each dose by an operation of heat-sealing the tablet in the width direction and an operation of the vertical heating roller 18 heat-sealing both side edges of the packaging sheet S.

The medicine packaging apparatus shown in the embodiment has the above-mentioned structure, and its operation will be described below.

Now, for example, two patients (A) and (B)
For example, the case where the same tablets are packaged separately for each patient will be described as an example. First, identification data of a patient, a medicine name for each patient, the number of tablets for one dose, and the number of packages are input to the input unit 12.

Based on the input, the control device 11 selects the tablet feeder 2 containing the corresponding tablet from the data, activates the motor b of the tablet feeder 2, and switches the two gates 8 of the tablet feeder 2 on. Let both open. In addition, the control device 11 includes packaging devices 15a and 15b.
On the other hand, for example, the first packaging device 15a is
The packaging device 15b is determined for the patient B.

The operation of the motor 6 of the tablet feeder 2 causes the rotor 4 to rotate at a constant speed. For this reason, pocket 5
The tablets stored in the inside are discharged from the first outlet 7a and the second outlet 7b at a certain interval and fall into the chute 10 connected to the outlets 7a and 7b, and the sensor provided on the chute 10 PH detects tablets. The detection signal is input to the control device 11.

The control device 11 compares the detection signal from the sensor PH with the data, and checks the outlets 7a and 7 of the tablet feeder 2.
When the number of tablets discharged from b reaches the required number for each patient, the gate 8 is closed.

When the number of tablets administered to patients A and B is different, 2
The two gates 8 are closed with a time lag, and when the two gates 8 are closed together, the motor 6 stops and the discharge of the tablet stops.

The tablets discharged from the first outlet 7a of the tablet feeder 2 to the chute 10 fall into the hopper 14a from the first drop guide path 13a, and are supplied to the first packing device 15a from the lower end outlet of the hopper 14a. It is then packaged for each dose. On the other hand, the tablets discharged into the chute 10 from the second outlet 7b pass through the hopper 14 from the second drop guide path 13b.
b, and is supplied quantitatively to the second packaging device 15b from the lower end outlet of the hopper 14b and is packaged for each dose.

Next, when different types of tablets are simultaneously packaged for two patients A and B, necessary data is input to the input unit 12 as described above.

The control device 11 includes packaging devices 15a, 15b
On the other hand, for example, the first packaging device 15a is
The packaging device 15b is determined for the patient B. The control device 11 selects two corresponding tablet feeders 2 and 2 based on the data, drives the motor 6 of the tablet feeders 2 and 2, and opens one of the gates 8.

At that time, the gate 8 of the second outlet 7b of the tablet feeder 2 for storing the tablet for the patient A is communicated with the second packaging device 15b for the patient B.

Each tablet feeder 2, 2 discharges a required number of tablets by driving the motor 6 of each tablet feeder 2, 2, as described above. The discharged tablets are supplied to the first and second packaging devices 15a and 15b to be packaged.

In the administration of tablets to a patient, several kinds of tablets of different types may be administered as one dose.
At the time of packaging, several types of tablet feeders 2 are operated by the operation of the control device 11, and tablets are discharged from one outlet, for example, the first outlet 7a of each feeder 2, and the tablets are dropped by the first dropper. A fixed amount is supplied from the guide path 13a to a first packaging device 15a provided thereunder for packaging.

In the embodiment, the tablet feeder 2 is provided with the first outlet 7a and the second outlet 7b. However, the number of outlets is not limited to this, and two or more outlets may be used. The number of packaging devices used is the same as the number of outlets, and tablets are supplied from each outlet to each packaging device.

[0034]

[0035] As described above, in the present invention, by quantitatively eject a tablet by opening a plurality of tablet outlets formed in the tablet feeder from each tablet outlet, tablets from each tablet outlet fall guide path and Since the tablets are dropped and supplied from the hopper to separate packaging devices, the same tablet can be simultaneously and efficiently packaged for a plurality of patients for each patient.

In addition, different types of tablets are stored in a plurality of packaging devices.
Can be supplied simultaneously at the same time.
Can simultaneously and efficiently pack tablets of different sizes
it can.
