Description

  The present technology relates to a powder packaging machine that distributes and packages powder. In particular, by preparing multiple cassettes containing individual powders and loading them on the shelf, the necessary amount of powders can be automatically transferred to the packaging device and packaged automatically according to the prescription. It relates to a powder medicine packaging machine.

  In powder dispensing operations, in the conventional device, the pharmacist measures the amount of one prescription for a predetermined drug in advance on the measuring table, and then puts it into the device, so that the distribution device can make the predetermined number of packets. The powder was divided, and the powdered powder was individually packaged by a packaging device.

  On the other hand, in recent years, a device capable of automatically weighing one prescription with a device as shown in Patent Document 1 has been put into practical use in order to reduce the burden of prior weighing work by a pharmacist. .

  Each of these devices employs a system in which containers containing a large number of medicines are arranged in advance on a shelf, and this is moved to a measuring unit using means such as an articulated robot or articulated chain movement. Due to structural limitations, the drug container used there could not be placed in a state visible from the front of the apparatus.

  Originally, from the viewpoint of operability, it is desirable that the medicine container used in such a device is easily accessible from the front of the device. It is easy to see what kind of medicine is contained in each container, and it is easy to remove and attach multiple containers at the same time even if the container is taken out and supplemented with medicine when the remaining medicine is insufficient. It is.

  For example, in Patent Document 1, a medicine container is installed in a container installation section of a multistage shelf provided on the outer peripheral surface of a vertical drum member that rotates in a substantially horizontal direction, and from there, a container by an articulated robot is used. When the medicine container is stored on the back side of the drum member, the medicine container is not visible from the front of the apparatus, and the medicine container is replenished with the medicine by the moving means. For this purpose, the drum member is rotated so that the predetermined drug container faces the front side, and the drug container is detached. For this reason, it was necessary to sequentially drive the drum member when replacing a plurality of drug containers at the same time.

  Another major problem is how to deal with measurement errors that occur rarely when weighing one prescription automatically. Such a phenomenon may occur as a measurement error due to an unintended external force applied to such a device, which becomes noise to the load cell for measurement.

  Patent Document 1 is a rotating disk distribution type powder medicine packaging machine, in which a medicine container is placed on a shaking table of a container placing device, and the medicine is dropped from the container placing device onto the distribution tray by vibration. In this case, the change in the weight of the container mounting device is measured by a weight measuring device, and the vibration is stopped when the fall amount reaches a desired weight.

  If the amount of fall exceeds the desired weight error range for some reason at this time, the corresponding powder is present on the disk, so it is difficult to collect it manually and dispense from the dispensing tray. Then, it must be collected after being wrapped and packaged and then opened.

  These collection operations are time-consuming but not impossible. However, if a measurement error occurs when multiple powders are weighed at the same time on a single distribution tray, the multiple chemicals are mixed on the distribution tray. Even if it can be recovered, a plurality of mixed powders cannot be separated, so that the amount of the drug must be discarded, and in the case of an expensive drug, a large economic loss occurs.

  Furthermore, in such a powder dispenser with a shelf for storing a fully automatic drug container, it is necessary to provide operational guidance and display of the state of the apparatus, and the screen becomes large. I want to place this screen on the front of the device so that it can be easily visually checked, while I want the drug container to be visible from the front. There is a problem that these two needs cannot be answered simultaneously.

Japanese Patent Laid-Open No. 11-180528

  In view of the above problems, the problem to be solved is that the powder storage container that needs to be processed can be visually observed and detached from the front of the machine, and the powder can be collected without any loss automatically when a measurement failure occurs.

  In this case, even if the container is arranged in a substantially flat shape on the front surface of the machine and a part of the container is shielded by a display or the like, a treatment, i.e., a place where there is no such shielding object, The parts that require confirmation of the contents / contents of the container, removal of the container, or installation of another container can be accessed by the operator from the front, so that the entire machine can be operated without sacrificing operability. Can be configured compactly.

Moreover, this invention is the powder medicine packaging machine of the one aspect | mode,
The powder temporary storage container that has been found to have a measurement error in the powder discharge part may be transferred to the powder container shelf by the powder container transfer device.

  If it does in this way, before discharging to a powder packaging apparatus, the powder temporary storage container with a measurement mistake can be excluded, and damages, such as disposal of a powder, can be minimized.

Moreover, this invention is the powder medicine packaging machine of the one aspect | mode,
An automatically readable code associated with the stored powder attached to the powder storage container;
-An automatically readable code associated with the stored powder attached to said powder temporary storage container;

  In this way, the powder storage container or the powder storage temporary storage container can be specifically arranged at the desired position of the powder container shelf described above, and the powder storage temporary storage container with the measurement error is stored in the powder storage. It is possible to return to the shelf and the like, and it is also possible to notify the operator of the contents by display, voice or the like on a display or the like.

Moreover, in order to solve the said subject, another aspect of this invention is a powder metering discharge device,
-A first powder discharge part capable of receiving a powder storage container which can store the powder stored therein and discharge it from the outlet, and discharge the powder therefrom;
A powder measurement unit capable of holding a powder temporary storage container capable of temporarily storing the powder released from the first powder discharge unit and measuring the weight of the powder released into the powder temporary storage container;

<Description of action>
The operation of the powder medicine packaging machine 1 configured as described above will be described.

<Mounting step for powder storage container and powder temporary storage container>
A powder storage container 100 storing a plurality of types of powders is mounted on a container mounting table 705 at an appropriate place in the powder container rack 700 in advance by an attendant. Similarly, a plurality of powder temporary storage containers 300 are also mounted at appropriate locations on the container mounting table 705. However, it is desirable to leave a plurality of places empty without mounting containers on all the container mounting tables 705.

  In addition, it is assumed that the information about the mounted container is written in advance by another device, and this is read by an RFID reader / writer (not shown), and the position of the container mounting table 705 and the information placed on the container mounting table 705 are read. The powder information of the existing container is linked and stored in the storage table.

<Transfer step to first powder discharge part of powder storage container>
Here, it is assumed that a prescription relating to a certain powder, for example, a prescription for dividing 20 g of powder A into 21 pieces and inputting them.

  The position of the container in which the powder A is stored is searched from the storage table, and the powder storage container 100 at this position is placed on the first powder discharger 200 by the powder container transfer device 800.

  FIG. 12 is a perspective view showing the operation of the powder container transfer device 800 of the powder packaging machine 1 according to one embodiment of the present invention.

  As shown in the right figure of FIG. 12, the table 806 of the powder container transfer device 800 is slid so as to be close to the powder container 100 of the container mounting table 705 of the powder container shelf 700, and the container held at the tip of the table 806 is held. While inserting the guide pins 810a and 810b of the portion 807 into the guide holes 104a and 104b of the powder storage container 100, the electromagnet 811 is operated to attract the side iron plate 105 of the powder storage container 100, as shown in the left view of FIG. Firmly hold the powder container 100.

  Next, while the powder storage container 100 is held by the container holding unit 807, the first moving unit 805, the second moving unit 803, and the first moving unit 801 of the powder container transfer device 800 perform the first movement. It is transferred to the powder discharger 200.

  FIG. 13 is a perspective view showing another operation of the powder container transfer device 800 of the powder packaging machine 1 according to one embodiment of the present invention.

  FIG. 13A shows a state in which the container holding unit 807 holds the powder storage container 100 and approaches the container mounting table 210 of the first powder discharge unit 200. In this way, the powder storage container 100 is transferred.

  FIG. 13B shows a state in which the powder storage container 100 moves from the state of FIG. 13A downward in the Z-axis, and the iron plate 106 at the bottom of the powder storage container 100 and the second electromagnet 213 provided on the container mounting table 210. It is in a state of being mounted on the container mounting table 210 by suction. In this way, the powder storage container 100 is firmly placed on the first powder discharge unit 200.

  FIG. 13C shows a state in which the excitation of the electromagnet 811 is stopped from the state of (b), the table 806 is moved in the Y-axis direction (rear), and the powder container transfer device 800 is separated from the powder container 100. Is shown. In this manner, the placement of the powder storage container 100 on the first powder discharge unit 200 is completed.

<Transfer step of powder storage container to powder measuring section>
Next, the empty powder temporary storage container 300 is placed on the powder temporary storage container mounting 402 of the powder measuring unit 400 by the powder container transfer device 800 in the same step.

  As described above, the powder temporary storage container mounting table 402 has the same configuration as the container mounting table 705 of the powder container shelf 700, and also the container mounting table 210 of the first powder discharge unit 200 (vibrating point). (Except for), since the configuration is substantially the same, the same operation can be realized.

<Discharge from powder storage container to powder temporary storage container and weighing step>
Next, when an alternating electrical waveform is input to the first electromagnet 225 of the first powder discharger 200, the iron material 211 exhibits a vibrational behavior such as being pulled toward or away from the first electromagnet 225.

  As a result, since the container mounting table 210 is attached to the intermediate table 223 via the leaf spring 224, the container mounting table 210 as a whole can perform vibration in which the vertical and horizontal directions in the drawing are combined.

  Thereby, the powder A falls to the powder temporary storage container 300, and the weight change is weighed by the platform 403. In this case, the vibration is stopped when the weight reaches 20 g, and the powder falling is stopped.

  Thereafter, the weight is again measured by the platform scale 403. This is because it takes several seconds until the weight instruction value of the weighing platform 403 is completely settled. If this value is within a predetermined error, the process proceeds to the next step.

  Note that the method of discharging the powder of the first powder discharge unit 200 is not limited to the method using an electromagnet, and may generate vibration by a piezoelectric element as long as the powder can be discharged little by little, or It is not limited, A spiral screw drive and other things may be used.

<Step of returning powder storage container>
However, if a predetermined error is exceeded at this time, the powder temporary storage container 300 is returned to the empty container mounting table 705 of the powder container shelf 700 by the powder container transfer device 800 and the RFID tag 307 is used. In addition, information regarding the measurement failure is written.

  The returning operation of the powder temporary storage container 300 may be performed in the reverse manner, so that the description thereof is omitted.

  Thereby, the powdered temporary storage container 300 in which a measurement error has occurred can be automatically removed regardless of the manpower, and the operation can proceed without stopping the machine. In addition, since the powder temporary storage container 300 in which a measurement error has occurred is returned to the powder container shelf 700, the operator can easily collect or dispose of the powder at an appropriate timing, improving work efficiency and discarding the powder. Loss can be minimized.

<Transfer to the second powder discharge part of the powder temporary storage container>
In the next step in the normal case, the measured powder temporary storage container 300 is transferred to the second powder discharge unit 500 in the vicinity of the disk distribution unit 610 of the powder packaging device 600 using the powder container transfer device 800. Then, it is mounted on the container mounting table 510. Since this transfer and mounting method is the same as the operation already described in FIG. 13, the corresponding numbers in FIG.

<Powder distribution step>
After this, a distribution operation using a known disk is performed. First, as a “disc rolling operation”, a powder is deposited on the disc 611 in a donut shape over the entire circumference (360 degrees), and then, as a “distribution operation”, the powdered powder is accumulated in a predetermined portion (not shown) In this case, it is distributed in 21 divisions) and released to the hopper chute 620, which is sequentially enclosed in the wrapping paper of the powder packaging part 630, and the packaging state of 21 prescriptions is completed.

  This disc rolling operation and distribution operation takes time. In parallel with this operation, the powder container transfer device 800 returns the powder medicine container 100 previously measured to the original container mounting table 705 of the powder container shelf 700, and the powder medicine container containing the powder of the next prescription. 100 can be transferred to the first powder discharger 200 and placed.

  Next, the empty powder temporary storage container 300 is mounted on the powder temporary storage container mounting table 402 of the powder measurement unit 400 immediately below the first powder discharge unit 200 by the powder container transfer device 800.

  Thus, the next prescription can be measured, so that the weighing operation can be performed independently of the disking operation and the distribution operation.

  Since two or more types of powders may be mixed in one prescription, in this case, the two left and right powder measurement units 400a and 400b can be operated in parallel.

<Container washing step>
FIG. 14 is a perspective view showing still another operation of the powder container transfer device 800 of the powder packaging machine 1 according to one embodiment of the present invention, in which FIG. 14 (a) is a normal position and FIG. 14 (b) is reversed. Shows the position.

  Here, as shown in the figure, the powder distribution temporary storage container 37 that has been emptied after completion of the disk-spinning operation in the disk distribution unit apparatus 400 is returned to the normal posture by the rotation drive unit 808 of the powder container transfer apparatus 800. The held container is turned upside down from the state of the rotating head 809a at the container holding position to the state of the rotating head 809b at the position reversed 180 degrees, and then mounted on the container cleaning device 700. The device is placed in an empty place on the mounting table 705, and a series of operations is completed.

<Reordering step>
In addition, when there is no prescription input in the powder medicine packaging machine 1, when the left and right doors 302 of the powder container shelf 700 are closed for the powder temporary storage container 300 that has failed to be measured earlier or the powder container 100 that has insufficient remaining amount. Then, the containers are rearranged using the container transfer device 800 at a position where the containers can be seen through the transparent cover 303.

  In this way, not all containers in the machine are visible from the front, but containers that need to be replaced are easily visible from the front.

  With the structure and action as described in detail so far, the following practical effects can be obtained in the automation of powder dispensing operations.

  First, a plurality of powder storage containers 100 are arranged on a powder container shelf 700 on the same surface on the front surface side of the powder packaging machine 1, and these are arranged on the XYZ orthogonal electric sliders 801, 803, 805. In the powder container transfer device 800 that can be transferred to each part in the above, the measurement for one prescription is not performed at the time of release to the disk part 611, but in the independent powder measurement part 400, By controlling so that the powder temporary storage container 300 that is stored in the powder temporary storage container 300 and only properly measured powder is discharged to the disk portion 611 and the powder temporary storage container 300 in which the measurement failure has occurred can be stored separately, some factor (external vibration, etc. ), It is no longer necessary to stop the machine by storing it separately.

  Secondly, the powder storage container 100 and the powder powder temporary storage container 300 can be stored in the empty container mounting table 705 on the powder container shelf 700 by matching the shapes thereof. As a result, even if the operation display 704 is arranged in such a way as to block a part of the powder container shelf 700 arranged on the front surface, the container that the staff actually needs to collect and replenish is the display 704 of the powder container shelf 700. Since the powder container transfer device 800 can be controlled so as to be rearranged in a place where it is not obstructed, no waste of powder occurs. Furthermore, it is possible to provide a fully automatic powder medicine dispenser 1 with extremely high operational convenience that allows a plurality of containers to be collected and replenished from the front while confirming the operation display 704 at an easily viewable position. .

  In the description so far, mutual transfer between the powder container shelf 700 of the powder storage container 100 and the first powder discharge unit 200, the powder temporary storage container 300 from the powder container shelf 700 to the powder measurement unit 400, The transfer from the powder discharger 400 to the powder container shelf 700 via the second powder discharger 500 or directly has been described, but other routes, for example, the powder container 100 are connected to the second powder discharger 500. A direct transfer route to is also possible. Depending on the convenience of the preparation, it may be advantageous. Other routes not listed are also available.

  In the description so far, the RFID tag is provided in the powder storage container 100 and the powder temporary storage container 300, and the RFID reader / writer is provided in the portion where the powder tag is placed or held. However, the present invention is not limited to this.
