DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a weighing-type fully automatic powder dividing method, a weighing-type fully automatic powder dividing device and a weighing-type fully automatic powder dividing and packaging device according to the present invention will be described with reference to the drawings. . FIG. 1 is a perspective view of a main part showing a configuration of a weighing-type full-automatic powder dividing and packaging apparatus. The weighing-type fully automatic powder dividing and packaging device (hereinafter referred to as a weighing-type packaging device) 20 divides a prescribed weight of powdered medicine M dispensed in the mortar 1 into a desired number and divides it into the paper bag 7 (see FIG. 2). It is a device for. After confirming that the powder M dispensed in the mortar 1 has a predetermined total weight on the scale 2, the powder M is divided into the set weight by the weighing type packaging device 20,
Each is packaged in a paper bag 7 as divided powder Ma (see FIG. 2). Here, the predetermined total weight is obtained by multiplying the set weight of the powdered medicine M prescribed as one dose by the number of doses (package number).

The weighing type packaging device 20 includes an auto feeder 30 serving as a powder supply means capable of dividingly supplying a set weight (a desired weight of a divided powder w) from the dispensed powder M, and a powder having a set weight from the auto feeder 30. M, a powder receiving section 40 to which M is supplied; an electronic scale 50 provided as a weighing means for measuring the total powder weight W and its change from the weight of the auto feeder 30; The control unit 60 includes a control unit 60 for performing control, and a packaging seal unit 70 that seals the powders divided and supplied to the powder receiving unit 40 by putting them into the paper bag 7 of the powder packaging. It should be noted that the auto-feeder 30, the powder receiving section 40, the electronic scale 50 and the control section 60 of the above-mentioned weighing type packaging device 20 constitute a weighing-type fully automatic powder dividing device.

The auto feeder 30 includes a hopper 31 for storing the powder M, a feeder 32 for guiding the powder M in the hopper 31 to drop into the powder receiving section 40, and a vibrator 33 for vibrating the hopper 31 and the feeder 32. It is configured with. Then, by activating the vibrator 33, the powder M in the hopper 31 is discharged.
, And has a function of dividing the set weight into the powder receiving section 40 by the feeder 32 to drop and supply the set weight of the powder. The control of the operation of the vibrator 33 is performed by the control unit 60, and the intensity of the vibration can be appropriately adjusted according to the properties of the powdered medicine M and the like.

The above-mentioned auto feeder 30
By mounting the entire apparatus on the electronic balance 50, the total weight of the entire apparatus including the powdered medicine M can be measured. The measurement value (weight) measured by the electronic balance 50 is input to the control unit 60 at a predetermined cycle (for example, every 0.1 second). In addition, the detection value of the electronic scale 50 has a vibration noise filter (not shown) in addition to the fact that the frequency band to be used is greatly different, so that it does not malfunction due to the influence of the vibrator 33. Since there is no change in the weight of the auto feeder 30 itself, the value is substantially a value obtained by measuring the change in the weight of the powdered medicine M.

In the powder receiving section 40, a cylindrical main body 41 is divided into an appropriate number (five in the illustrated example) of powder discharging chambers 42, and at the bottom of each powder discharging chamber 42, as shown in FIG. An opening / closing bottom cover 43 is provided as opening / closing means. The powdering chamber 42 is divided by a partition plate 44 arranged radially from the center of the axis of the main body 41. Each of the powdering chambers 42 is rotated about the axis by driving means (not shown) in which the main body 41 is controlled by the control unit 60. By rotating in the direction of the arrow, the feeder 32 is moved.
, And a powder discharge position where the received powder is supplied to the packaging seal 70. At the powder discharge position, the hopper 8 is located below the powder chamber 42, and by opening the openable bottom lid 43 under the control of the control unit 60, the divided powder Ma is passed through the hopper 8 to the paper bag 7 It is to be thrown into.

In addition to controlling the operations of the above-described components, the control unit 60 calculates the divided medicine weight w from the detection initial value of the electronic balance 50 and decreases the detection initial value by the divided medicine weight w. In the meantime, control of the weighing-type fully automatic powder splitting method of operating the vibrator 33 of the powder feeding means 30 can be performed. The control unit 60 includes:
An operation surface (not shown) having a display screen, various keys, various switches, and the like is provided so that necessary items such as the number of packages can be input and operations such as turning on / off the device can be performed. .

In such a weighing-type fully automatic powder dividing method, in the first weighing step, the value is a value measured before the vibrator 33 is actuated, and means the total powder weight W actually present in the hopper 31. The detection initial value to be measured is measured. In the subsequent packaged weight calculation step, the total weight of the powdered medicine W obtained in the weighing step is divided by the number of divided packages to be divided, and a divided powdered medicine weight w indicating the weight of the powdered medicine to be divided at this stage is calculated. Therefore, the divided medicine weight w calculated here is
Is the division weight when a certain powder is actually equally divided. In the powder supply step after calculating the divided powder weight w, the vibrator 33 is operated to drop the powder in the hopper 31 from the feeder 32 into the powder chamber 42 of the powder receiving section 40 at the powder receiving position. The detection value (powder weight) is input to the control unit 60 from the electronic balance 50 at a predetermined cycle, and the detection value decreases by the divided powder weight w (W-
When w) is reached, the operation of the vibrator 33 is stopped.

As a result, the weight of one package of the powdered medicine is measured by the electronic balance 50 and the hopper 3 of the auto feeder 30 is measured.
The powder is dropped and dropped to the powder receiving section 40 and temporarily stored in the powder chamber 42. At this time, the powder in the air when the vibrator 33 is stopped, that is, the powder falling from the feeder 32 to the powder chamber 42 is not included in the measurement of the electronic balance 50. For this reason, if an appropriate time is provided until the powder medicine chamber 42 is rotated, the falling powder medicine can be divided into the same powder medicine chamber 42 as the dropped medicine before the vibrator 33 stops. Thereafter, similarly, the weighing step, the package weight calculation step and the powder supply step are sequentially repeated to divide the powder into a desired number of packets.

The packaging seal section 70 is a device for sealing and packaging one package of the powdered medicine supplied from the hopper 8 in the paper bag 7. One package of powder, which has been put into the paper bag 7 from the powder dispensing chamber 42 via the hopper 8, is sealed for each bag by a known method such as welding the opening of the paper bag 7.

Hereinafter, the weighing type packaging apparatus 20 having the above-described configuration will be described.
The procedure for dividing and packaging powdered medicine M according to the above will be specifically described.
First, the total weight of the powdered medicine M dispensed in the mortar 1 is measured with the scale 2, and it is confirmed that the powder M has a predetermined weight. This powder M
The powder is transferred from the mortar 1 to the hopper 31 of the auto feeder 30 in a stopped state, the necessary items are input from an operation surface (not shown), and the switch is turned on. Thereafter, the powder M is divided and divided automatically. You.

When the switch of the weighing type packaging device 20 is turned on, first, the weight of the auto feeder 30 is measured by the electronic balance 50. As a result, the total weight (W) of the powdered medicine M actually present in the hopper 31 as the detection initial value
Is measured and input to the control unit 60. (Weighing step) The control unit 60 having received the input of the total powdered weight W divides the total powdered weight M by the number of packages N inputted from the operation surface,
From this, the divided powder weight w of the powder M to be divided is calculated.
Since the calculated weight of the powdered powder w is a value obtained by dividing the total weight of the powdered medicine W actually present by the number of packets N, even if the total weight of the powdered medicine W has an error within an allowable range, The error will be evenly distributed. (Packing weight calculation process)

After calculating the divided powder weight w in this manner, the vibrator 33 is operated to drop the powder M from the feeder 32 to the powder chamber 42 at the powder receiving position to be divided. During this time, the weight measured by the electronic balance 50 is input to the control unit 60 at a predetermined period as short as about 0.1 second, and the vibrator is operated until the detected value becomes a value obtained by subtracting the divided powder weight w from the powdered total weight W. The operation of 33 is continued. In other words, the vibrator 33 is operated to drop the powder M in the hopper 31 into the powder chamber 42 until the powder M in the hopper 31 reaches the weight (W−w) reduced by the divided powder weight w. To split. (Powder supply process)

FIG. 3 shows the relationship between the operating time t of the vibrator 33 and the divided powder weight w which is equal to the powder fall weight. The time t is from 0 to t1, the vibrator 33 is operated, and The divided powder weight w1 is dropped and divided. At this time, the control unit 60 slightly delays the data processing until the stop time of the vibrator 33 is determined based on the detection value input at a predetermined cycle and the vibrator 33 is actually stopped. For this reason, an error occurs in the weight w1 of the packaged medicine that falls due to such a time lag, and it is preferable to correct the operation time t to prevent this. That is, in order to prevent the surplus drug powder from falling due to a delay in the stop time of the vibrator 33, the vibrator 33 may be stopped in advance by a time lag in advance. Since such a time lag is a constant value determined by a circuit configuration, a device configuration, and the like in the control unit 60, the weight of the powdered medicine falling during the time lag is predicted, and the operating time t1 of the vibrator 33 is shortened accordingly. Then, the correction may be made by earlier operation stop. Since the weight of the powder falling during the time lag changes depending on the properties of the powder, the intensity of vibration of the vibrator 33, and the like, properly setting this setting affects the division accuracy.

When the vibrator 33 that has been activated until time t1 stops, the first vibrator 33 including the one that is falling at the time of stop is stopped.
The powder in the package is divided into a powder chamber 42 in which the bottom lid 43 is closed. At this time, the operation of the vibrator 33 is stopped until time t2. During this time, the powdered medicine falling is collected in the powdered medicine chamber 42, and the total weight W of the powdered medicine remaining in the hopper 31 is measured by the electronic balance 5.
A second weighing step of measuring at 0 is performed. After collecting the falling powder, the powder receiving section 40 is rotated by one of the powder chambers 42, and the adjacent empty powder chamber 42 is rotated.
To the powder receiving position.

Thereafter, the total powder weight W measured in the second weighing step is divided by the number of divided packets (N-
Divide by 1) to calculate the divided powder weight w to be divided for the second time. If there is an error in the weight of the first divided powder, the divided powder weight w calculated here is a value corrected for this error. That is, when the first divided weight has an error on the plus side, the divided divided medicine weight w calculated by the second division is smaller by a value obtained by dividing the plus part by the divided number (N-1). On the other hand, when an error on the minus side occurs, the divided powder weight w, which is calculated to be larger by the value obtained by dividing the minus part by the number of packages (N-1) in the second division, is adopted. Is done. Accordingly, the same correction is performed each time the third and subsequent divisions are performed, so that errors are accumulated on the plus side or the minus side, leaving a large error, and the last one package of powdered medicine is within the specified error range. It can be prevented from becoming small or large enough to deviate from the range.

After calculating the second divided powder weight w in this way, the vibrator 33 is activated from time t2, and the powder M is dropped from the feeder 32 to the powder chamber 42 moved to the powder receiving position and divided. During this time, the electronic balance 5
The weight measured at 0 is input to the control unit 60 at a predetermined cycle similarly to the first time, and the operation of the vibrator 33 is continued until the detected value becomes a value obtained by subtracting the divided powder weight w from the powdered total weight W. Is done. That is, the weight of the powder M in the hopper 31 is actually reduced by the divided powder weight w (W-
Activate the vibrator 33 until time t3 when
The powdered medicine M in the hopper 31 is dropped into the powdered medicine chamber 42 to divide the second divided medicine weight w2. In this case, it goes without saying that the stop time t3 of the vibrator 33 is advanced by the time lag described above.

When the vibrator 33 that has been operated until time t3 stops, the second vibrator 33 including the one that is falling down at the time of stop is stopped.
The powder in the package is divided into a powder chamber 42 in which the bottom lid 43 is closed. Here, the operation of the vibrator 33 is stopped until time t4. During this time, the powdered medicine falling is collected in the powdered medicine chamber 42, and the total weight W of the powdered medicine remaining in the hopper 31 is measured by the electronic scale 5
A third weighing step of measuring at 0 is performed. After collecting the falling powder, the powder receiving section 40 is rotated by one of the powder chambers 42, and the adjacent empty powder chamber 42 is rotated.
To the powder receiving position.

Thereafter, the third and subsequent division / packing is repeated in the same manner, but the divided divided medicine weight w divided at the first time is used.
When the powder medicine chamber 42 containing the powder medicine 1 is rotated to the powder medicine discharge position, the bottom cover 43 is opened and the powder medicine in the powder medicine chamber 42 is put into the paper bag 7. The paper bag 7 in which the powdering is completed is
Since the packaging is completed by moving one package and sealing the opening by the packaging seal unit 70, the powder receiving unit 40
Can be supplied with the divided powder at the powder receiving position, and at the same time, the powder can be charged into the paper bag 7 and sealed at the powder discharging position.

Since the powder M is divided and packaged by the above-described dividing method and the apparatus to which the method is applied, even if an error occurs in the divided powder weight w of one packet at each division, the next dividing and dividing is performed. In the packaging, the powder weight obtained by calculating the divided powder weight w from the actually existing powder weight W and correcting the error is divided and divided, so that the error is accumulated and remains as the last one packet. It is possible to prevent the powdered total weight W from being less than the prescribed package weight of ± 10% or exceeding the prescribed package weight. That is,
The error is recognized by measuring the total weight W of the powdered medicine that actually exists, and the weight of the next divided powdered medicine w is determined so that the correction reflecting the error is made. High divisional packaging can be performed.

Since the weight of the auto feeder 30 is directly measured by the electronic balance 50 and the powder receiving and the powder discharging can be performed at the powder receiving position and the powder discharging position at the same time, the number of parts as a whole can be reduced. A small and inexpensive device can be provided. In addition, since the properties of the powdered medicine M vary depending on the type, if the vibration intensity of the vibrator 33 is made variable, the powdered medicine which is hard to fall is given a strong vibration to shorten the falling time, and the whole required for divided packaging. It is also possible to make adjustments so as to shorten the work time.

The weighing-type packaging device 20 of the present invention is not limited to the one shown in FIG. 1; for example, it measures not only the total powder weight W from the change in the total weight in the auto feeder 30 but also the powder M The weight change of a part of the auto feeder 30 including the hopper 31 therein may be measured.

According to the above-described weighing-type fully automatic powder dividing method, weighing-type fully automatic powder dividing device and weighing-type powder dividing / packing device of the present invention, after measuring the total weight of the dispensed powder, The correction value is calculated by measuring the weight of the powdered powder actually divided, and the divided packaging based on the set weight and the divided packaging based on the corrected set weight obtained by adjusting the correction value are alternately performed. For this reason, weight measurement is not performed at all except for measuring the total weight after dispensing, and compared to the conventional method of dividing and packaging the entire volume, each device has a simple and inexpensive device configuration. We can weigh the weight of the powder to be divided and make corrections,
More accurate division and packaging is possible. The above correction is 1
It will be more accurate by performing each package,
If the average value is corrected for a plurality of packages as a group, the number of measurements can be reduced, so that the time for the divided packages can be reduced, and both accuracy and work efficiency can be achieved.
