It has become.
[0024]
Hereinafter, the operation of the medicine packaging device by the control device 15 will be described with reference to the flowchart of FIG.
[0025]
First, when various conditions of the packaging operation are input by the input means 33 and the start switch is operated, the packaging preparation process is started (step S1). In this packaging preparation process, the pulse motor 23 is driven and rotation of the distribution tray 17 is started. Then, the piezoelectric element 20 is driven, and the medicine is discharged from the medicine supply hopper 16 through the feeder 19. During this time, if the discharge state of the medicine by the sensor 21 is detected and it is determined that all the medicine has been discharged from the medicine supply hopper 16, the driving of the pulse motor 23 and the piezoelectric element 20 is stopped. Thereby, the discharged | emitted chemical | medical agent is accommodated equally in the accommodation groove | channel 22 of the distribution tray 17, and a packaging preparation process is completed.
[0026]
Subsequently, the packaging process is started (step S2). In this packaging process, the ultrasonic vibration member 8 is driven to start the vibration of the medicine injection hopper 3. Further, as shown in FIG. 3, the bottom plate 7 is driven to open the lower opening of the medicine charging hopper 3. Then, the opening / closing member 4 of the cleaner device 1 is moved to open the rectangular hole 5 of the base plate 2. Further, the heat sealing motors 29 a and 29 b and the printing unit 28 are driven to print on the packaging sheet 27, and a substantially triangular bag portion 27 a is formed below the medicine charging hopper 3. Therefore, the scraping device 18 is driven to scrape out one package of medicine, and the medicine is stored in the bag portion 27a of the packaging sheet 27 via the medicine charging hopper 3. Then, the heat sealing motor 29 is driven to seal the bag portion 27a. Thereafter, the medicine is packaged one by one in the same manner, and when the packaging for all the medicines supplied to the distribution tray 17 is completed, the packaging process is terminated.
[0027]
Here, if the type of medicine to be packaged is changed, the cleaning process in the medicine charging hopper 3 is started as follows. The change in the type of medicine is automatically determined based on an input signal from the input means 33. However, the cleaning process may be automatically performed every time the packaging of all the medicines supplied to the distribution tray 17 is completed.
[0028]
First, the opening / closing member 4 is slid to close the rectangular hole 5 of the base plate 2, that is, the upper opening of the medicine charging hopper 3 as shown in FIG. 2 (step S3). As a result, the medicine injection hopper 3 and the suction device 9 communicate with each other via a communication path constituted by the first communication port 11, the internal space of the opening / closing member 4, the second communication port 12, and the hose 10. In addition, by driving the bottom plate 7 of the medicine injection hopper 3, an opening / closing operation is performed between a position where the lower opening is closed and a position where the lower opening shown in FIG. 2 is slightly opened (step S4). Furthermore, the medicine injection hopper 3 is vibrated by the ultrasonic vibration member 8 (step S5). And the drive of the suction device 9 is started and the air in the medicine injection hopper 3 is sucked together with the remaining medicine (step S6). The drug adhering to the inner surface of the drug charging hopper 3 is detached by vibration by the ultrasonic vibration member 8. Further, since the bottom plate 7 of the medicine charging hopper 3 is opened and closed between a position where the lower opening is closed and a position where it is slightly opened, the inside of the medicine charging hopper 3 is once subjected to a negative pressure, The air flows in from the high speed, and the turbulent state is effectively discharged to discharge the remaining drug to the communication path. When a set time (3 seconds in the present embodiment) at which it is determined that the medicine in the medicine feeding hopper 3 has been removed to a level where there is no problem has passed (step S7), the ultrasonic vibration member 8 and the suction device 9 are passed. Is stopped (steps S8 and S9), and the bottom opening of the medicine injection hopper 3 is closed by the bottom plate 7 (step S10). Further, the opening / closing member 4 is slid to open the upper opening of the medicine injection hopper 3 as shown in FIG. 3 (step S11), thereby preparing for the next packaging process.
[0029]
The suction device 9 is stopped in the cleaning process based on the set time, but may be performed based on the amount of air sucked by the suction device 9, for example.
[0030]
Further, the opening / closing member 4 is made of a material such as synthetic resin so as to have flexibility, so that the opening / closing member 4 is disposed so that a slight gap is formed between the opening / closing member 4 and the base plate 2. Then, it can be elastically deformed by the suction force in the cleaning process and brought into close contact with the base plate 2. According to this, the opening / closing member 4 has no friction with the base plate 2 except for the cleaning process, and the opening / closing member 4 can be smoothly moved. It can be effectively removed.

Below the base plate 41, a medicine injection hopper 44 and a discharge duct 45 positioned on the side thereof are arranged. In addition, a predetermined gap dimension is formed between the base plate 41 and the medicine input hopper 44 and the discharge duct 45, and an opening / closing member 46 is slidably disposed therein. The opening / closing member 46 is a plate-like body made of a flexible material such as a synthetic resin material, and the thickness thereof is formed to a value smaller than the gap size. Thereby, the sliding movement of the opening / closing member 46 is possible. In addition, the opening / closing member 46 has a first series opening 47 communicating with the upper opening of the medicine charging hopper 44 in a state where the upper opening of the medicine charging hopper 44 is closed, and a suction opening 45a of the discharge duct 45. And a second communication port 48 communicating with each other. Both the communication ports 47 and 48 are communicated with each other by a casing 49 provided on the upper surface of the opening / closing member 46. The opening / closing member 46 is guided by a bearing 50 having both side portions provided on the lower surface of the base plate 41. Further, the opening / closing member 46 slides in the direction of the arrow in the drawing via a rack (not shown) integrated with the side edge and a pinion (not shown) provided on the rotating shaft of the motor 51. ing.
[0033]
The cleaner device 40 according to the second embodiment is used for the cleaning process in the medicine injection hopper 44 as in the first embodiment. In this cleaning processing method, when suction by a suction device 9 (not shown) is started, the opening / closing member 46 is elastically deformed downward to seal the upper opening of the medicine injection hopper 44 and to the second communication port 48. And the suction port 45a of the discharge duct 45 are communicated in a sealed state. Thereby, the sealing performance in the communication path from the medicine charging hopper 44 to the suction device 9 can be improved, and the residual medicine in the medicine charging hopper 44 can be effectively removed. Further, when suction by the suction device 9 is not performed, the sliding movement of the opening / closing member 46 can be performed smoothly by the gap between the base plate 41 and the medicine injection hopper 44 and the discharge duct 45.
[0034]
FIG. 7 shows a cleaner device 60 according to the third embodiment.
[0035]
This cleaner device 70 is different from that according to the second embodiment in that a hose 63 extending from a suction device (not shown) is directly connected to a communication port 61 formed in the opening / closing member 62, and a base plate 64, the medicine input hopper 65 or the like base plate 41 of the second embodiment is similar to the drug agent dispenser hopper 44 or the like.
