The control unit 90 includes a packing machine 21, a drive unit 27, a belt conveyor 31, a solenoid 80, an interface unit 91, a drug detection sensor 92, and a dropping drug detection sensor. The 86, the display unit 12, the input unit 13, and the storage unit 93 are connected.

The packing machine 21 creates the distribution filled with the predetermined | prescribed chemical | medical agent by the control of the control part 90, and conveys the created distribution to the discharge port 10 by the conveyor 45 as mentioned above.

Under the control of the control unit 90, the drive unit 27 swings the rocking arm provided in the drive unit 27 to drop the medicine from the tablet case 22 downward by one tablet.

The belt conveyor 31 is rotated in the direction indicated by the arrow Y1 in FIG. 2 under the control of the control unit 90, and the chemical agent dropped from the tablet case 22 positioned above the belt conveyor 31 is transported to the conveyor end 31A. ), The chemicals are dropped from the conveyor end 31A toward the hopper 29 to introduce the chemicals into the hopper 29.

The solenoid 80 makes the shutter 74 in the closed state open under the control of the control unit 90. As a result, the medicines temporarily collected on the shutter 74 are discharged to the wrapping paper through the medicine outlet 72.

The interface unit 91 is connected to the personal computer 95 via a signal communication cable or the like, and transmits and receives various signals to and from the personal computer 95 under the control of the control unit 90. With this configuration, various types of data can be transmitted and received between the personal computer 95 and the medicine supply device 1, and the operator gives various instructions to the medicine supply device 1 via the personal computer 95. It can be carried out.

The drug detection sensor 92 detects a drug discharged from the tablet case 22 and outputs a detection value to the controller 90. The controller 90 counts the number of drugs discharged from the tablet case 22 based on the detection value input from the drug detection sensor 92.

The falling medicine detection sensor 86 detects a medicine passing (falling) between the light emitting part 87 and the light receiving part 88 in the medicine drop passage 71 and outputs the detected value to the controller 90. The counter unit 90A of the control unit 90 counts the number of drugs that have dropped the drug drop passage 71 based on the detection value input from the drop drug detection sensor 86.

The display unit 12 displays various types of information under the control of the control unit 90. The input unit 13 receives an input operation of a user and outputs it to the control unit 90.

The storage unit 93 is composed of an EEPROM or a flash memory, and stores various data in a rewritable manner under the control of the control unit 90.

The chemical | medical agent supply apparatus 1 of the said structure aims at shortening the time taken for the operation which fills a chemical | medical agent in a wrapping paper, and prepares a distribution by performing the following operation | movement. Hereinafter, the operation of the drug supply device 1 will be described using a flowchart.

7 is a flowchart showing the operation of the medicine supply device 1 when preparing the distribution.

Prior to the preparation of the distribution, the operator inputs information indicating the type and quantity of medicines to be filled in the distribution to the personal computer 95 based on the prescription made by a doctor or the like (step SA1). Data representing the information input to the personal computer 95 is output to the control unit 90 via the interface unit 91, and the control unit 90 stores the data in the storage unit 93 as the filling agent data. The drug supply device 1 continuously produces a distribution based on the filled drug data.

After input to the personal computer 95 by the operator, the control unit 90 starts discharging the medicine of a predetermined type and quantity from the tablet case 22 (step SA2). Specifically, the control unit 90 specifies the tablet case 22 containing the medicines to be filled in the distribution created by referring to the filling drug data, and controls the driving unit 27 from the specific tablet case 22. Drop the medicine downward by 1 tablet. At this time, the drug detection sensor 92 detects the drug discharged from the tablet case 22 and outputs the detection value to the control unit 90. The controller 90 counts the quantity of medication discharged from the tablet case 22 based on the detection value input from the medicine detection sensor 92, and controls the driving unit 27 at the stage where the predetermined quantity is discharged. Stops falling.

After the drug starts discharging from the tablet case 22 in step SA2, the timer unit 90B of the control unit 90 starts counting the drug collection time D1 (step SA3). Here, drug collection time D1 is demonstrated. Assuming that the drug is discharged from a tablet case 22 and then the drug is introduced into the nozzle 36 through the drug introduction portion 30 and the hopper 29, the time for collecting the drug is called nozzle collection time. The time D1 is set to a time longer than the nozzle collection time of the tablet case 22 which is located in the place where the nozzle collection time is longest among the plurality of tablet cases 22. For example, if the nozzle collection time of the tablet case 22 with the longest nozzle collection time is 10 seconds, the drug collection time D1 is set to 15 seconds. Therefore, when the medicine collection time D1 has passed after the medicine is discharged from the tablet case 22, the medicine discharged from the tablet case 22 is surely introduced into the nozzle 36.

In addition, after the drug starts discharging from the tablet case 22 in step SA2, the counter 90A of the control unit 90 counts the number of drugs dropping the drug dropping passage 71 of the nozzle 36. It starts (step SA4).

Next, the control part 90 determines whether the fall of a chemical | medical agent is detected based on the detection value of the fall medicine detection sensor 86 (step SA5). When the drop of the medicine is detected (step SA5: YES), the counter unit 90A of the control unit 90 counts the number of the drugs on which the drop is detected (step SA6), and counts the medicine with reference to the filling drug data. It is determined whether the number reaches the number of drugs to be filled in the distribution (step SA7). If the counted number of drugs reaches the number of drugs to be filled in the distribution (step SA7: YES), since all drugs to be filled in the distribution are introduced into the nozzle 36, the control unit 90 The count of the number of drugs falling down the chemical dropping passage 71 of the nozzle 36 is finished (step SA8), and the solenoid 80 is controlled to keep the shutter 74 open and remain on the shutter 74. The medicine is dropped and filled into the wrapping paper through the medicine outlet 72 (step SA9). After filling the packing paper with the medicine, the control unit 90 controls the packing machine 21 to divide the packing paper filled with the medicine for each bag, and cuts the packing paper for each one, so that the distribution of the medicine of the desired type and quantity is filled. It prepares and conveys to the ejection outlet 10 (step SA10). Next, the control unit 90 determines whether or not all distributions have been created (step SA11). If not, the control unit 90 returns the processing to step SA2 and ends (step SA11: NO). Step SA11: Example) The process ends.

On the other hand, when the fall of the medicine is not detected in step SA5 (step SAS: no), or when the number of drugs counted in step SA7 does not reach the number of drugs to be filled in the distribution (step SA7: no), the controller 90 determines whether or not drug collection time D1 has elapsed (step SA12). If the drug collection time D1 has not elapsed (step SA12: NO), the control unit 90 returns the process to step SA5 to again determine whether or not a drop of the drug is detected. On the other hand, when the chemical | medical agent collection time D1 has passed (step SA12: Yes), the control part 90 complete | finishes the count of the number of the chemical | medical agents which fall the chemical | medical agent dropping path 71 of the nozzle 36 (step SA13). Although the drug collection time D1 has passed in this step SA13, the number of drugs counted by the counter 90A does not reach the number of drugs to be filled in the distribution.

Here, although the drug collection time D1 has passed, the number of drugs counted by the counter unit 90A does not reach the number of drugs to be filled in the distribution, for example, the light receiving unit 88 and the light emitting unit. A plurality of drugs may overlap and fall at the same time between (87), and these drugs may be detected as one drug. In this case, the number of drugs counted by the counter unit 90A does not reach the number of drugs to be filled in the distribution. Based on this, in this embodiment, when the medicine collection time D1 which is the time which the medicine discharged | emitted from the tablet case 22 is surely introduced into the nozzle 36 has passed, the medicine counted by the counter part 90A of the medicine | medical agent counted. Even if the number does not reach the number of drugs to be filled in the distribution, the count of the number of drugs is finished.

After finishing counting the number of falling drugs in step SA13, the control unit 90 controls the display unit 12 so that the number of drugs counted by the counter unit 90A does not reach the number of drugs to be filled in the distribution. The result is displayed, and the operator is notified of the effect (step SA14). The operator recognizes that the distribution is created in such a state that the number of drugs counted based on the notification does not reach the number of drugs to be filled in the distribution, and checks the contents of the distribution. In addition, in step SA14, the control unit 90 may prompt the operator to put a certain mark on the distribution to the printer 41.

After the notification, the control unit 90 controls the solenoid 80 to make the shutter 74 open, drops the medicine staying on the shutter 74, and fills the wrapping paper through the medicine outlet 72. (Step SA9). After filling the packing paper with the medicine, the control unit 90 controls the packing machine 21 to divide the packing paper filled with the medicine for each bag, cut each packet, and then distribute the medicine filled with the desired type and quantity of medicine. Is prepared and conveyed to the ejection opening 10 (step SA10). Next, the control unit 90 determines whether or not all distributions have been created (step SA11). If not, the control unit 90 returns the processing to step SA2 (step SA11: NO). SA11: ex) End the process.

After the discharge of the medicine is finished, the time of the medicine collection time D1 is started, and the medicine collection time D1 elapses at the elapsed time T3. As described above, the drug discharged from the tablet case 22 is certainly introduced into the nozzle 36 at the time when the drug collection time D1 has elapsed. The shutter 74 is opened at the elapsed time T3 after the medicine collection time D1, and is closed at the elapsed time T5 when the predetermined time has elapsed. At the elapsed time T5, the preparation of the distribution is started using the wrapping paper filled with the medicine from the nozzle 36, and the medicine to be filled in the next distribution is discharged from the tablet case 22.

Next, the operation timing of the medicine supply apparatus 1 which concerns on this embodiment is demonstrated using FIG. 8 (B).

As shown in FIG. 8B, the predetermined medicine is discharged from the tablet case 22 at the elapsed time T0, and the discharge of the predetermined medicine is finished at the elapsed time T1. After the discharge of the medicine is finished, the number of drugs falling down the medicine drop passage 71 of the nozzle 36 is counted, and at the stage when the number of drugs counted at time T2 reaches the number of drugs to be filled in the distribution, The count ends. Since the chemical | medical agent discharged from the tablet case 22 is introduce | transduced into the nozzle 36 in time shorter than chemical | medical agent collection time D1, time T2 which complete | finishes counting is the elapsed time of chemical | medical agent collection time D1 in FIG. 8 (A). The time is earlier than the time T3.

The shutter 74 enters the open state at time T2 when the count of the drop medicine is finished, and becomes closed at the elapsed time T4 after a predetermined time has elapsed. At the elapsed time T4, the preparation of the distribution is started using the wrapping paper filled with the medicine from the nozzle 36, and the medicine to be filled in the next distribution is discharged from the tablet case 22. Here, as is clear from the comparison of Figs. 8A and 8B, the drug supply device 1 according to the present embodiment is an elapsed time which is the discharge timing of the tablet case in the conventional drug supply device. In the elapsed time T4 earlier than T5, the next drug is discharged from the tablet case, which shortens the time required for preparation of the distribution.

As described above, in the present embodiment, the dropping drug detection sensor includes a shutter 74 in which the nozzle 36 temporarily collects the medicine, and detects the medicine passing through the medicine dropping passage 71 of the shutter 74. And a control unit 90 for opening the shutter 74 in accordance with the detection result of the falling chemical detection sensor 86.

For this configuration, in the case of filling the wrapping paper with the medicine introduced into the nozzle 36 by making the shutter 74 open when preparing the distribution, the medicine is discharged from the tablet case 22. Without waiting for the elapse of drug collection time D1, the shutter 74 is opened when the predetermined number of drugs are counted by the falling drug detection sensor 86, and the next drug is discharged from the tablet case 22. can do. Thereby, as shown in the timing chart of FIG. 8, compared with the conventional chemical | medical agent supply apparatus 1, time taken for the operation | work which produces a distribution can be shortened.

In addition, in this embodiment, the counter part 90A of the control part 90 counts the number of the chemical | medical agents which drop the chemical | medical agent dripping passage 71 of the nozzle 36 based on the detection value of the falling chemical | medical agent detection sensor 86. . This configuration enables the shutter 74 to be opened when the number of drugs counted by the counter unit 90A of the control unit 90 reaches a predetermined number, and as described above, the distribution It is possible to realize a shortening of the time required to create a.

Moreover, in this embodiment, after discharging a medicine from the tablet case 22, the timer part 90B of the control part 90 measures medicine collection time D1. And although the medicine collection time D1 has passed, when the number of drugs counted by the counter part 90A does not reach the number of drugs which should be filled in distribution, the shutter 74 will be opened and a nozzle ( The medicine is filled into the wrapping paper from 36).

Here, although the drug collection time D1 has passed, the number of drugs counted by the counter unit 90A does not reach the number of drugs to be filled in the distribution, for example, the light receiving unit 88 and the light emitting unit. A plurality of drugs may overlap and fall at the same time as (87), and the plurality of drugs may be detected as one drug. In this case, the number of drugs counted by the counter 90A does not reach the number of drugs to be filled in the distribution. Based on this, in this embodiment, when the medicine collection time D1 which is the time which the chemical | medical agent discharged | emitted from the tablet case 22 is surely taken in into the nozzle 36 has passed, the chemical | medical agent counted by the counter part 90A Even if the number does not reach the number of drugs to be filled in the distribution, the count of the number of drugs is completed, and the shutter 74 is opened. Thereby, even if all the chemical | medical agents which need to fill a distribution are introduce | transduced in the nozzle 36, the situation that a distribution is not created can be prevented.

In addition, in this embodiment, the falling chemical | medical agent detection sensor 86 is provided in the chemical | medical agent drop passage 71 extended in a perpendicular direction. Therefore, the chemical | medical agent which falls down the inside of this chemical | medical agent fall passage 71 perpendicularly | vertically can be detected reliably by the falling chemical | medical agent detection sensor 86. FIG.

In addition, in this embodiment, the chemical | medical agent is discharged from the tablet case 22 by the position in the tablet case storage part 23 of the tablet case 22, and until this chemical | medical agent is introduce | transduced into the nozzle 36, The time is of a different configuration. For example, above the belt conveyor 31, the time from when the chemical | medical agent is discharged from the tablet case 22 located in the front right end until this chemical | medical agent is introduce | transduced into the nozzle 36, and the inclination plate 32 Above, the electrons are a long time from the time the drug is discharged from the tablet case 22 located at the front left end until the drug is introduced into the nozzle 36. By performing the operation | movement shown in the flowchart of FIG. 7 in this structure, as shown in the timing chart of FIG. 8, time regarding creation of distribution can be shortened.

In addition, embodiment mentioned above shows one kind of this invention to the last, and can be arbitrarily modified and applied within the scope of the present invention.

For example, in this embodiment, the chemical | medical agent supply apparatus 1 provided with the structure which introduce | transduces the chemical | medical agent discharged | emitted from the tablet case 22 into the hopper 29 using one belt conveyor 31 in the chemical | medical agent introduction part 30. ) Has been described as an example, but this may be a device that does not use the belt conveyor 31 or a device that uses a plurality.
