Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder supply apparatus, and more particularly, to a powder supply apparatus for supplying an appropriate amount of powder from a large number of stock powders to a powder packaging process.

[0002]

2. Description of the Related Art Conventionally, various powder packaging machines (divider).
Has been proposed. For example, a large number of cells for accommodating powders may be arranged in a straight line or may be arranged in a ring to form a divided cell, and the powdered medicines are distributed almost uniformly along the divided cells. In some cases, the bottom plate is sequentially opened one by one, and the powder is introduced into a packaging device installed below to separate the packages one by one.

In addition, instead of the annular divided mass, a rotating body having an annular groove whose cross section is depressed in an arc shape is used. While rotating this rotating body at a constant speed, powdered medicine is applied to the entire circumference of the groove. After almost evenly distributing, while rotating the rotating body by the angle according to the number of divisions, cut out the powder for that angle sequentially,
In some cases, the package is introduced into a packaging device installed below, so that packages are packaged one by one.

Further, there is an automatic powder dispenser capable of handling each type of powder and automatically performing the dispensing operation, unlike these dividing devices (Japanese Patent Laid-Open No. 8-8090).
No. 2). In this method, the powdered medicine is taken out from each stock case by using a powder-powder-spouting device provided for each stock case, and the powdered medicine is received and packaged using a mobile packaging device. .

[0005]

However, in such a conventional dividing device, a prescribed amount of powder to be packaged is taken out of a storage container and put into a hopper of a commonly used vibrating feeder for distribution. Must be performed by the pharmacist for each type of powdered medicine,
The burden on the pharmacist is large and cannot be said to be sufficient for an automatic machine. Further, the conventional automatic powder dispensing and packaging machine has a problem that it requires complicated mechanisms such as a large number of powder ejection devices and a movable packaging device, and is therefore complicated and expensive.

Therefore, it is an important issue to develop and provide a powder packaging machine having these advantages. That is, while introducing a new powder supply device that does not require a powder ejection device, and combining such a powder supply device with a conventional dividing device, an appropriate powder from a large number of powdered powders is stored in the dividing device. By supplying an appropriate amount, the dividing device can be flexibly and inexpensively converted into a sophisticated automatic machine.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to realize a powdered medicine supply apparatus which automatically takes out and supplies an appropriate amount of various powdered medicines.

[0008]

Means for Solving the Problems The configuration, operation and effects of the powdered medicine supply device of the present invention which has been made to solve such problems will be described below.

The powder supply device of the present invention (as described in claim 1 at the time of filing the application) has a large number of powder cassettes for removably stocking powders and a cassette for sequentially moving these powder cassettes to a powder removal position. A moving mechanism, wherein a driven mechanism for taking out the powdered medicine is incorporated in the powdered medicine cassette, and a driving mechanism for taking out the powdered medicine is arranged near the powdered medicine taking-out position.

Here, the above "many" is generally about several tens to several hundreds, but if it is three or more, it corresponds.

In the powdered medicine supply device having such a configuration, various kinds of powdered medicine are stored in a large number of powdered medicine cassettes, and are appropriately taken out therefrom in accordance with prescription information and the like. In the case, powder supply to a subsequent device such as a packaging machine is automatically performed. In addition, the powder is transported while being accommodated in the powder cassette to the powder take-out position, so that it is still trapped during this time. Further, at that time, the powdered medicine cassette that has been moved to the take-out position is taken out by driving the driven mechanism by the drive mechanism. Therefore, one or a small number of drive mechanisms are commonly used for removing powder from a large number of powder cassettes.

This makes it possible to automate the taking out and supply of appropriate amounts of various powders even if they are difficult to take out compared to tablets and the like. In addition, since the powdered medicine is not taken out until the powdered medicine cassette moves to the take-out position in such automation, the movement distance in the released state of the powdered medicine is short, so the powdered medicine may fly even if it is fine particles. There is almost no. Further, in addition to the automatic powder supply with little dissipation, the drive mechanism is shared so that the device can be simplified and downsized. Therefore, according to the present invention, it is possible to easily realize a powder supply apparatus that automatically and appropriately takes out and supplies various powders in appropriate amounts.

The drive shaft 41 is moved forward with respect to the driven mechanism of the cassette 30 that has come to the powder take-out position to establish the connection. 2B (that is, the state shown in FIG. 2B is changed to the state shown in FIG. 2C). On the other hand, the drive shaft 41 is retracted to release the connection with the cassette 30 (that is, the state shown in FIG. ))). As a result, the drive section 40 (drive mechanism for taking out the powder) is arranged in the corresponding cassette storage unit B, C, E, F in the vicinity of the powder take-out position.

The electronic balance 50 is installed between the upper and lower belts 11 of the transport mechanism 10 at a position slightly below the cassette 30 at the powder take-out position (see FIG. 2). The electronic balance 50 has a bearing piece 5 that can be raised or lowered alone or together with the main body.
1, the cup 1 conveyed by the belt 11 to just below the outlet of the discharge path 35 of the cassette 30 is supported from the cut of the belt 11 and weighed only when it rises ( (See FIG. 3). Then, when the powdered medicine is taken out of the cassette 30 into the cup 1 there, the weighed value increases by the amount of the powdered medicine. Thereby, the electronic balance 50 (metering device) measures the powdered medicine taken out from the powdered cassette 30.

A reader / writer 52 is attached to the electronic balance 50 in addition to or integrated with them (see FIG. 3). The non-contact coupling element 53 of the reader / writer 52 is disposed between the pair of bearing pieces 51 and can be communicatively coupled to the data carrier 3 of the weighing cup 1. Thus, the reader / writer 52 (data access device) is arranged corresponding to the weighing device.

A reader / writer 54 is provided behind the electronic balance 50 and the like.
6 is provided at a location where it can be communicatively coupled to the device (see FIG. 3). As a result, the reader / writer 54 (data reading device) is arranged corresponding to the powder take-out position.

Further, a cassette 30 is provided at a front door (not shown).
In order to remove the empty cassette 30 from the cassette circulating mechanism 20 or to attach the cassette 30 after powder replenishment to the cassette circulating mechanism 20, the opening window is usually formed through the opening window. Done through.
A reader 56 is installed at the back of the opening window, and a non-contact coupling element 57 is provided at a position where the non-contact coupling element 57 can be communicably coupled to the data carrier 36 of the cassette 30 in a non-contact manner (FIG. 1). reference). Thereby, the reader 56
The (data reading device) is arranged at a place where the powdered medicine cassette is attached to and detached from the cassette moving mechanism.

The feeder 60 takes the powder taken out of the cassette 30 (powder cassette) into the cup 1 and is conveyed together with the cup 1 by the conveying mechanism 10 or the like, and the powdering and packaging machine 70.
(Segmentation device), cassette storage unit F
Is provided near the end of the transport mechanism 10 and above the powder dispenser 70 (see FIG. 1). The feeder 60 receives the powder transferred from the cup 1, a guide 62 for feeding the powder from the hopper 61 to the annular groove 72 of the powder packing machine 70, and allows the feed to be performed uniformly and quantitatively. Therefore, the vibrating body 63 generates vibration applied to the guide portion 62 and the like. The vibrating body 63 vibrates at the same frequency as the oscillation signal received from the oscillation circuit 64. The oscillation circuit 64 changes the oscillation frequency according to a control signal from the controller 80. Thus, the feeder 60 (vibration feeder) has a variable vibration frequency.

The controller 80 is a computer system for control and is connected to the above-described motors, reader / writers, and the like via an interface (I / F), and also holds routines and data for performing various processes. I have. That is, a cassette mounting routine 81, a prescription input routine 82, a container supply routine 83, a cassette moving routine 84, a powder ejection routine 85, and a weighing routine 8
6. Container moving routine 87, feeder control routine 8
8. The packaging control routine 89 and the like are installed, and the specific processing is exemplified in the following operation description.

It should be noted that the powdered medicine data 91 contains
Each piece of medicine information is stored for each category. The prescription data 92 stores prescription target drug information. The container data 93 is allocated to each cup 1 in use for ease of management, and a plurality of container data 93 are generated when a plurality of cups are used to take out a powdered medicine in one prescription. The package data 94 stores a part or all of the prescription data 92 converted so as to be compatible with the process of the powder packaging machine 70.

The mode of use and operation of the powder supply device of this embodiment will be described.

First, since various kinds of powder used for dispensing must be stored in each cassette 30, when powder is not enough, necessary powder is supplied to the appropriate cassette 30 using the powder replenishing machine 4. I do. At this time, the powder carrier 4 is stored in the data carrier 36 of the cassette 30.
, The corresponding drug information is written. When the cassette 30 is mounted on the cassette circulating mechanism 20 of any of the cassette storage units B, C, E, and F of the powder supply device, the medicine information is read out by the reader 56 of the mounted unit and the cassette is read. It is stored in the powdered medicine data 91 by the mounting routine 81.

When the preparation of the preparation is completed,
When drug information to be dispensed is input from a host computer (not shown), a keyboard (KBD), or the like based on the prescription, the drug information is set in the prescription data 92 by a prescription input routine 82. At that time, the prescription data 92
Is also converted into package data 94.

Then, based on the prescription data 92, the container supply routine 83 sets the container data 93 and controls the cup supply mechanism 14. Specifically, two cups 1 are used, and the first cup 1 takes out the powdered medicine of the first cassette 30 and the powdered medicine of the second cassette of the cassette storage unit E. Third cassette 30 of storage unit C
It is assumed that the setting has been made to take out the powdered medicine.

Then, the first cup 1 is supplied from the cup supply mechanism 14 onto the transport mechanism 10 of the cassette storage unit B. The first cup 1 has a container movement routine 8
7, is transported through the cassette storage units B and C and the cup lifting unit D to reach the cassette storage unit E by the transport mechanism 10 and the cup lifting mechanism 15, and the unit E is moved by the transport mechanism 10 there.
To the powder removal position in

When the first cup 1 moves from the cassette storage unit B to the cassette storage unit C, the transfer operation of the units C, D, E, etc., is performed in parallel.
The second cup 1 is supplied from the cup supply mechanism 14 onto the transport mechanism 10 of the cassette storage unit B. The second cup 1 is transported in the cassette storage unit B to the cassette storage unit C by the transport mechanism 10 that operates under the control of the container movement routine 87, and the powdered medicine removal in the unit C is performed by the transport mechanism 10 there. Brought to the position.

In parallel with the transport of the cups, the cassette circulation mechanism 20 of the cassette storage units C and E operates under the control of the cassette moving routine 84, and the third cassette 30 and the first cassette 30 are respectively moved. The powder is moved to the corresponding powder removal position. In this way, preparations for quickly taking out the powder from the cassette 30 into the cup 1 are completed.

Then, the cassette storage units C and E
Of the third and first cassettes 30 by the reader / writer 54 of
The drug information is read from the data carrier 36 of. Then, an association check between the medicine information and the medicine data 91 or the prescription data 92 is performed by the medicine taking out routine 85, and when the medicine information does not match, the processing shifts to error processing. In this way, it is confirmed whether or not the cassette 30 at the powder removal position is appropriate. For example, an error occurs when the cassette 30 is improperly replaced in an unmanageable state such as when the controller 80 is down.

If no error is found in the cassette 30 at the powder take-out position, the corresponding drive unit 40 is coupled to and drives the cassette 30 at the powder take-out position under the control of the powder take-out routine 85. Thus, in the cassette storage unit C, the powdered medicine is taken out from the third cassette 30 into the second cup 1, and in the cassette storage unit E, the powdered medicine is taken out from the first cassette 30 into the first cup 1.

At the same time, the first and third cups 1 are also weighed by the corresponding electronic balance 50 under the control of the weighing routine 86. When the amount of the powdered medicine to be taken out reaches the required amount, the taking-out of the powdered medicine is stopped by the cooperation of the metering routine 86 and the powdered medicine taking-out routine 85.
Further, by the processing of the weighing routine 86, the amount of the removed powder is written to the data carrier 3 of each cup 1. Other related information held in the powdered medicine data 91 and the like, for example, information such as the range of the vibration frequency of the feeder 60 suitable for feeding the powdered medicine by the feeder 60 is also written.

Thus, the second cup 1 containing the required powdered medicine is transported toward the cassette storage unit E by the transport mechanism 10 of the cassette storage unit C and the cup lifting mechanism 15 of the cup lifting unit D. On the other hand, in the cassette storage unit E, the cassette circulation mechanism 20 there
As a result, the second cassette 30 is moved to the powder taking-out position, and the powder in the second cassette 30 is taken out and added to the first cup 1 by the processing of the powder taking-out routine 85 and the weighing routine 86.

Then, the first cup 1, which has also finished storing the required powdered medicine, is carried to the feeder 60 by the transport mechanism of the cassette storage units E and F, and by the cup storage mechanism 16 of the cup storage unit G. The powder inside is transferred to the feeder 60. Subsequently, the second cup 1 is similarly conveyed to the feeder 60, and the stored powdered medicine is transferred to the feeder 60. Thus, based on the prescription, the powders in the first to third cassettes 30 are taken out by a predetermined amount and collected in the feeder 60.

At the time of this transfer, the medicine information on the powdered medicine stored from each data carrier 3 of the first and second cups 1 is read by the reader 58, and the container data 9 is read by the feeder control routine 88.
A confirmation process is performed to determine whether or not the number matches 3 or the like. If they do not match, the process proceeds to error processing. In this way, it is confirmed whether the cup 1 carrying the powder is appropriate. For example, if the cup 1 drops from the belt 11 and the appropriate cup 1 does not reach the feeder 60 where there is no sensor for detecting the presence or absence of the cup 1, an error is detected.

If no error is found in the cup 1 that has reached the feeder 60, data for generating a control signal to the oscillation circuit 64 is set by the processing of the feeder control routine 88 from the collected medicine information for each powdered medicine. Is done. Specifically, as the preferable range of the vibration frequency of the feeder 60, the frequency range “150” to “200” is read for the powder from the first cassette 30, and the frequency is read for the powder from the second cassette 30. Range "17
0 ”to“ 250 ”are read out, and the frequency range“ 400 ”to“ 460 ”for powder from the third cassette 30 is read.
Is read.

In such a case, the overlapping parts are put together,
Frequency range “150” to “250” and frequency range “40”
"0" to "460" are data values for generating a control signal to the oscillation circuit 64 (see FIG. 4A), thus processing such as the feeder control routine 88 (control means of the vibration feeder). Accordingly, when the vibration frequency of the vibration feeder 60 is swept in a predetermined range, the setting is changed so that the predetermined range is dispersed according to the powdered medicine taken out.

Then, under the control of the feeder control routine 88, the feeder 60 feeds the powder into the annular groove 72, which rotates at a constant speed, of the powder packaging machine 70 while vibrating. At this time, the vibration frequency of the feeder 60 has a value “15”.
After sequentially changing from 0 to the value "250", it jumps to the value "400" at a stretch, and then changes to the value "460" at a stretch, then jumps back to the value "150" and repeats the same change again. (See FIG. 4B.) The number of cycles is appropriately set by the feeder control routine 88 according to the amount of powdered medicine and the like.

In this way, various powders can be quickly and smoothly supplied at the respective resonance frequencies to the annular groove 7 of the powder packaging machine 70.
2 are distributed substantially evenly over the entire circumference. Then, when the distribution is completed, the cutting plate of the cutting device 73 is repeatedly rotated by one rotation while rotating the annular groove 72 by an angle corresponding to the number of divisions corresponding to the predetermined number of packages. The powdered medicine in the concave groove 72 is cut out by an amount corresponding to one packet, and is sequentially put into the hopper 74 of the packaging device. In response, the packaging device in the powder dispensing and packaging machine 70 packages the powder one by one.

In this manner, the prescribed powder stored in each cassette 30 is prescribed in a prescribed amount and is divided into a prescribed number of packets.

When a maintenance work is to be performed on the powder packaging machine 70, particularly when the annular groove 72 is to be cleaned, it is necessary to take measures for almost the entire upper portion of the powder packaging machine 70. However, it is often difficult to secure a sufficient working space in front of the device. In such a case, the operation on the powder packaging machine 70 is performed as follows.

First, the mounting plate 75 on which the powder packaging machine 70 is mounted is pulled out as far as possible in front of the apparatus (see FIG. 6A). If the powder dispensing and packaging machine 70 is exposed even if it is a part thereof, the exposed portion is cleaned by cleaning the annular groove 72 or the like. Then, while releasing the lock of the rotating plate 76 and rotating the rotating plate 76 appropriately, the same operation is continued for a newly exposed portion (see FIG. 6B). In this way, it is possible to easily take measures even on a portion of the annular groove 72 or the like that is not exposed only by being pulled out (see FIG. 6C).

[0058]

As is apparent from the above description, in the powder supply apparatus of the present invention, it is possible to automate taking out and supplying an appropriate amount of various powders, and at the time of the automation, the powder cassette is moved to the take-out position. By preventing the powder from being taken out until the powder has moved, the travel distance in the released state of the powder is short, so that even if the powder is fine, it can be prevented from scattering. Further, in addition to the automatic supply of the powdered medicine with less dissipation, the common use of the drive mechanism has an advantageous effect that the apparatus can be simplified and downsized.
