Next, FIG. 11 shows a block diagram of the control device 44 of the solid preparation filling device 1 of the present invention. The control device 44 is composed of a general-purpose microcomputer 45. The microcomputer 45 is connected with a transmitting / receiving means 46 for transmitting / receiving data to / from an external personal computer (not shown), and the input terminal has the above-mentioned structure. The photo sensor 13 of the discharge counting device 8, the holder position detection sensor 41 of the holder device 31, the bar code reader 42, and the key switch 43 are connected.

At the output terminal of the microcomputer 45, the drum rotation motor 10 for driving the discharge drum 9, the turntable motor 18, the holder motor 39,
The shutter opening / closing means 24 and the display device 47 are connected.

The operation of the solid preparation filling device 1 of the present invention having the above structure will be described below with reference to FIGS. FIG. 13 is a flowchart of a program for the solid formulation discharging operation of the microcomputer 45, and FIG. 14 is a flowchart of a program for the solid formulation filling operation of the microcomputer 45.

The shutter 2 is turned on when the power is turned on.
Reference numeral 3 indicates that the discharge port 22 of the guide 21 is closed and each count value and the like are reset. Further, it is assumed that the turntable motor 18 is always energized, so that the turntable 16 is constantly rotating. However, when the dispensing work is stopped for a certain period of time, the turntable 16 can be temporarily stopped.

Further, the discharge drum 9 is stopped, the centrifugal arm 61 is pushed by the spring 64 and separated from the friction wall 54, the shield plate 51 is pulled by the spring 58, and the shield portion 53 closes the outlet 7A. is doing. Therefore, since the outside air does not normally enter into the tablet case 7 through the outlet 7A, the inconvenience that the solid formulation 5 absorbs moisture to be deteriorated or collapsed is eliminated. Furthermore, even if the tablet case 7 is attached or detached for the purpose of supplementing the solid preparation 5 or cleaning the tablet case 7, the solid preparation 5 does not fly out from the outlet 7A.

In this state, when the operator inputs the prescription data to the personal computer based on the doctor's prescription, the personal computer makes a data transmission request to the solid formulation filling device 1. When the microcomputer 45 of the solid preparation filling device 1 receives the data transmission request from the personal computer by the transmitting / receiving means 46 in step S1, next, in step S2, the solid preparation 5 is stored in all the holders 33 of the holder device 31. Is held and full, and if full, the process returns to step S1 and waits.

If the holders 33 ... Are not full in step S2, the microcomputer 45 replies to the personal computer in the data waiting state in step S3, and receives the prescription data sent from the personal computer accordingly. Then read. Then, in step S4, based on the prescription data, the drum rotation motor 10 of the discharge counting device 8 of the tablet case 7 that stores the solid preparation 5 of the type specified by the prescription data.
Is driven to rotate the discharge drum 9 in the direction of the arrow in FIG.

The rotation of the discharge drum 9 causes the centrifugal arm 6 to rotate.
1 also rotates together, but at this time, the centrifugal arm 61 resists the urging force of the spring 64 by the centrifugal force and rotates about the rotation shaft 62 in the direction in which the weight 63 at the other end moves outward. As a result, the outer surface of the centrifugal arm 61 comes into contact with and is pressed against the inner surface of the friction wall 54, so that the frictional force at this time resists the biasing force of the spring 58, and the shielding plate 51 is also rotated in the rotation direction of the discharge drum 9. It By this rotation, the shield portion 53 of the shield plate 51 opens the outlet 7A as described above (see FIG. 1).
2). The centrifuge arm 61 is set to a size such that any part of the centrifugal arm 61 comes into contact with the friction wall 54 and the outlet 7A is opened during the rotation of the discharge drum 9.

Further, as the discharge drum 9 rotates, the solid preparation 5 drops from the groove 11 which coincides with the outlet 7A opened as described above, as described above. Brush member 14 between the formulations 5 and 5
Since the solid formulation 5 on the upper side is retained by holding the solid formulation 5 on the upper side, only the solid formulation 5 at the lowermost portion below the brush member 14 falls from the groove 11. Therefore, as the discharge drum 9 rotates, one solid preparation 5 is dropped from each groove 11 ...

As described above, the solid preparation 5 dropped from the groove 11 through the outlet 7A by the rotation of the discharge drum 9 is received by the turntable 16 through the passage 12, and the number of the falling solid preparations 5 is the same as the above photo. The microcomputer 45 counts based on the output from the sensor 13. Then, in step S5, it is determined whether or not the count ends, and if not, the process returns to step S4 and is repeated. When the number of drops of the solid preparation 5 detected by the photo sensor 13 matches the number of solid preparations 5 based on the above-mentioned prescription data, the microcomputer 45 determines that the counting is completed, and the drum rotation motor 10
The energization is stopped and the process proceeds from step S5 to step S6.

The discharge drum 9 is stopped by stopping the power supply to the drum rotation motor 10. However, when the rotation of the discharge drum 9 is changed (slowed) and the centrifugal force acting on the centrifugal arm 61 is reduced, the centrifugal arm 61 is immediately moved. It is pushed inward by the spring 64 and separated from the friction wall 54. Thereby, the shielding plate 5
1 is pulled back by the spring 58 and the outlet 7A is closed by the shield 53.

Therefore, even after the power supply to the drum rotation motor 10 is stopped, the solid preparation 5 is prevented from being discharged from the groove 11 even if the discharge drum 9 continues to rotate due to inertia (actually, an extremely short period). Excessive discharge is reliably prevented. Therefore, the rotation speed of the discharging drum 9 can be increased and the time required for discharging can be shortened.

Further, the solid preparation 5 in the tablet case 7 is charged with static electricity due to the rotation of the discharge drum 9, etc., but the solid preparation 5 in the groove 11 comes into contact with the conductive plate 66 when it reaches the lowermost portion. Therefore, the electric charge charged on the solid preparation 5 is discharged to the outer case 3 through the conductive plate 66 and the conductive plates 67 and 68.

In this way, since the solid preparation 5 is discharged, the inconvenience that the solid preparation 5 is adsorbed to the tablet case 7 and the discharge drum 9 to cause defective discharge is avoided.

On the other hand, the solid preparation 5 dropped on the turntable 16 moves toward the outer guide 21 by the centrifugal force of the rotating turntable 16. At this time,
A raised portion 1 is provided at the center of the turntable 16 having a weak centrifugal force.
Since 6A is formed, the solid preparation 5 dropped to this portion moves outward due to the inclination of the raised portion 16A, and then moves toward the guide 21 by centrifugal force. Further, since the turntable 16 is provided with the partition wings 17, 17 and rotates together, the solid preparation 5 that is stationary on the rotating turntable 16 is also smoothly pushed outward. In this way, the solid preparations 5 dropped on the turntable 16 are collected inside the guide 21 and are pressed against the guide 21 in a line.

Next, in step S6, the microcomputer 45 selects the vacant holder 33, drives the holder motor 39 to rotate the holder device 31, and, on the basis of the holder position detection sensor 41, moves the guide 21 of the guide 21. The empty holder 33 is positioned below the discharge port 22. Next, in step S7, the microcomputer 45 rotates the shutter 23 outward by the shutter opening / closing means 24 as shown in FIG. 5, and opens the discharge port 22 for a predetermined time (for example, 1 second) and closes it.

When the discharge port 22 is opened, the solid preparations 5 lined up in a line inside the guide 21 are sequentially collected by the centrifugal force into the discharge port 22 and flow out from there, and are positioned below. From the inlet 33A of the holder 33, it flows into the holder 33 and is filled (step S8).

The microcomputer 45 repeats the above steps S4 to S8 for all kinds of solid preparations 5 designated by the prescription data, and fills different holders 33 ... With respect to each kind.

On the other hand, the operator attaches a bar code label L on which a bar code indicating one of the patient name and the solid preparation 5 designated by the prescription data is printed on the side surface of the bottle V as a predetermined container. paste. Then, when the bar code of the bar code label L is read by the bar code reader 42 when it is inserted into the filling section 3B from the insertion port 6 of the solid formulation filling device 1. The microcomputer 45 is shown in FIG.
In step S9 of 4, it is determined whether or not the barcode (type of solid preparation 5) read by the barcode reader 42 has been read. Judge whether it is already filled. Then, if it is not filled yet, the process returns to step S9 and stands by.

Then, when the holder 33 is filled with the solid preparation 5 of the type in step S8, the microcomputer 45 proceeds from step S10 to step S11 to select the holder 33 filled with the solid preparation 5. Drive the holder motor 39 to rotate the holder device 31,
In addition, the holder 33 is positioned on the insertion opening 6 based on the holder position detection sensor 41.

In this state, when the inlet of the bottle V is directed to the lower side of the outlet 33B of the holder 33 and the lid 36 is opened by the handle 37, the solid preparation 5 of the type is filled from the holder 33 into the bottle V (step). S12).

Next, FIG. 15 shows another embodiment corresponding to FIG. 9 of the tablet case 7 and the discharge counting device 8 of the present invention. In this case, the shielding plate 51 is not provided with the shielding portion 53, and instead, the width of the base portion 52 is enlarged, and the entire outer portion thereof is below the entire range in which the groove 11 of the discharge drum 9 rotates. To position. Further, a through hole (or notch) not shown is formed in the base portion 52, and the base portion 5 is always provided.
2, the outlet 7A is closed, and when the discharge drum 9 is rotated, the through hole is aligned with the outlet 7A.
It is designed to open.

In particular, the shielding plate 51 in this case is made of a conductive material such as a metal plate, and the conductive plate 7 is formed on the lower surface thereof.
1 contacts. The conductive plate 71 is grounded via the conductive plates 67 and 68 similar to the above.

According to this embodiment, the shield plate 51 can be used also as the conductive plate 66 of the above embodiment,
It is possible to reduce the size of the conductive plate 71 to improve the assembly workability and reduce the material cost.

[0054]

As described above in detail, according to the present invention, since the outlet through which the solid preparation falls is always closed and the outlet is opened during the discharging operation by the discharging means, the tablet case is usually provided. Since there is no invasion of outside air into the inside from the outlet, the inconvenience that the solid preparation absorbs moisture and is deteriorated or collapsed is eliminated. Further, even if the tablet case is attached or detached for supplementing or cleaning the solid preparation, the solid preparation can be prevented from jumping out from the outlet.

Further, since the outlet is closed when the discharging operation is stopped, the excessive discharging can be surely prevented, and the accurate filling operation can be realized.

Particularly, as the discharging means (discharging drum) rotates,
Due to the centrifugal force, the outlet can be opened and closed by the shielding means (shielding plate), so it is not necessary to provide a special electric drive device for opening and closing the outlet, and the production cost can be reduced. At the same time, it becomes possible to contribute to energy saving.

Further, since the shielding means (shielding plate) closes the outlet when the discharging means (discharging drum) is stopped, the excessive discharging can be prevented even if the rotating speed of the discharging means (discharging drum) is increased. The time required for discharging and filling can be shortened.

According to the invention of claim 3, in addition to claim 2, since the shielding plate is made of a conductive material and is grounded, the solid preparation in the tablet case is destaticized to smooth the solid preparation. Since it is possible to realize various discharging and filling operations, and since the electricity is removed by using the shielding plate, it is possible to reduce the material cost and improve the assembling workability.
