Description

The present invention relates to a drug packaging machine that stores various drugs and automatically discharges and packages a desired drug according to a prescription or a dispensing instruction. The present invention relates to a drug packaging machine that collects drugs by a drug collecting mechanism, and more particularly, to an improvement of a drug packaging machine in which an upper drug collecting mechanism of the drug collecting mechanism is housed in a drug storage unit that houses a drug feeder.

As a drug packaging machine capable of packaging various drugs (see, for example, Patent Documents 1 to 7), a tablet packaging machine for packaging tablets, a powder packaging machine for packaging powder, or a mixture of tablets and powder can be used. There are powdered tablet packaging machines that can be packaged individually, but most of them have a drug storage section with a large number of drug feeders and a long two one after another that receive the drug in the input hopper. A packaging device that separates and encloses in foldable packaging paper, a drug collection mechanism that collects drugs discharged from appropriate drug feeders and delivers them to the above packaging device, and dispensing instructions based on prescription information, etc. It is equipped with a control device such as a computer for controlling the operation of the above-mentioned drug feeder and the packaging device according to the above.

Of these parts, the tablet feeder is a combination of a drug cassette that can contain a predetermined drug and a base that holds it detachably, of which the latter base mechanically engages the drug cassette. It is equipped with a static member such as a seating member that is held by such as, and a dynamic member such as a motor that drives a rotary disk for discharging a drug of a drug cassette, and is often arranged in a row on a shelf board or the like. , A cassette storage space is secured above it. Then, when the control device causes the base portion of the drug feeder of the drug to be dispensed to perform a discharge operation in response to the dispensing instruction, the drug to be dispensed is discharged from the drug cassette of the corresponding drug feeder, and the drug is dropped by its own weight. After being collected by the drug collection mechanism, it is guided into the loading hopper of the packaging device, and is packaged by the packaging device in appropriate units such as morning, day, night, and night dose units.

Further, in the case of a drug packaging machine capable of equipping a drug hangar with a large number of drug feeders for handling drugs such as tablets suitable for sequential discharge in a three-dimensional arrangement (see, for example, Patent Documents 1 to 3), the drug feeders are arranged two-dimensionally. The drug feeder hangars that can be equipped in the above are housed in the drug storage section side by side, and at least the upper drug collection mechanism of the drug collection mechanism is arranged between the drug feeder hangars (for example, patent). See Document 1).
Then, when the drug feeder hangar is pulled out from the drug storage section (see, for example, Patent Document 2), one side of the upper drug collecting mechanism is exposed (see, for example, Patent Document 3), so that the inside of the upper drug collecting mechanism is cleaned. can do.

On the other hand, in the case of a drug packaging machine in which the number of drug feeders mounted is smaller than that (see, for example, Patent Documents 5 to 7), the one having a shorter depth than the vertical and horizontal lengths of the drug storage portion is such that the drug feeder is attached and detached. It has been put into practical use because it is easy to use from the viewpoint.
In that case, since the cassette of the drug feeder is attached and detached from the front of the drug storage, all or part of the upper drug collection mechanism of the drug collection mechanism is arranged on the rear back portion of the drug storage to avoid it. To. Therefore, cleaning of the upper back surface portion of the upper drug collection mechanism is performed after removing the back plate of the drug storage portion to expose the inner surface of the upper drug collection mechanism.

Japanese Unexamined Patent Publication No. 2005-192702 Japanese Unexamined Patent Publication No. 2006-109860 Japanese Unexamined Patent Publication No. 2011-182890 Japanese Unexamined Patent Publication No. 2004-250001 Japanese Unexamined Patent Publication No. 2001-087353 Japanese Unexamined Patent Publication No. 2016-073518 Japanese Patent Application No. 2018-000887 (application)

In such a drug packaging machine, the upper drug collecting mechanism is composed of a so-called vertical split structure in which two vertical plates with bent side portions are arranged facing each other, and any of the vertical plates has further workability and durability. In general, stainless steel is used in consideration of stain resistance and the like.
Therefore, the inside of the upper chemical collection mechanism cannot be wiped or even seen unless the facing vertical plate is pulled apart and opened, so cleaning is required due to increased adhesion of chemical dust. It was difficult to visually confirm in advance whether the condition was reached or not.

In the case of a drug packaging machine equipped with a large number of drug feeders (see, for example, Patent Documents 1 to 3), it is suitable for places with many prescriptions for packaging such as large-scale pharmacies, and is generally frequently used. In addition to being able to carry out inspections reasonably from a cost perspective, emergency inspections are also performed immediately when a problem occurs, and the elapsed time from the previous cleaning to the next cleaning of the inside of the upper drug collection mechanism is maintained sufficiently shorter than the estimated time to reach the dirt limit. Therefore, it was less necessary to open the upper drug collection mechanism and visually check it before deciding whether or not to clean the inside of the upper drug collection mechanism.

On the other hand, in the case of a drug packaging machine with a small number of drug feeders (see, for example, Patent Documents 5 to 7), it is suitable for places with few prescriptions such as small-scale pharmacies, and is generally used infrequently or even varies. In many cases, it is costly to carry out inspections by a professional maintenance worker at a desirable cycle, so the user decides whether cleaning or even repairing the inside of the upper drug collection mechanism is necessary. It is necessary to open the upper drug collection mechanism and visually check the inside prior to cleaning or the like.
Although the frequency of cleaning is low, the frequency of visual confirmation is high.

However, in the case of a drug packaging machine with a small number of drug feeders (see, for example, Patent Documents 5 to 7), a complicated and robust structural part such as pulling out the drug feeder storage from the drug storage section together with the upper drug collection mechanism (see Patent Documents 5 to 7). (See, for example, Patent Document 3) is almost unnecessary, and whether the one-sided split of the upper drug collecting mechanism is arranged immediately inside the back plate (see, for example, Patent Documents 5 and 6), or the back plate is the upper drug collecting mechanism. In many cases, it also serves as a half-split (see, for example, Patent Document 7). You can check.

However, even if it is a half-split, the upper drug collecting mechanism is quite large, so that the desorption work is a heavy burden on the user. Further, when the upper drug collecting mechanism is fully opened, the dust and the like of the adhering drug are likely to fly up, so that the preparation for preventing and reducing the inhalation and dissipation thereof becomes a burden on the user.
Therefore, in order to reduce these burdens, it is a technical issue to realize a drug packaging machine that can easily visually check the inside of the upper drug collecting mechanism without opening the upper drug collecting mechanism widely.

The drug packaging machine of the present invention (Solution 1) was devised to solve such a problem.
Among the drug collection mechanisms, it is equipped with a drug storage unit equipped with a plurality of drug feeders capable of accommodating and sequentially discharging drugs, and a drug collection mechanism that receives the drugs discharged from the drug feeder and collects them while dropping their own weight. An upper drug collecting mechanism located next to the drug feeder is arranged near the outer surface of the drug storage portion, and the upper drug collecting mechanism is also used as an outer plate or a plate-shaped lid portion on the outer plate side. In a drug packaging machine that is designed to be removed or opened to expose the inside
A viewing window capable of exposing a part of the inside of the upper drug collecting mechanism is formed in the plate-shaped lid portion, and a window closing member for closing the viewing window is provided.

Further, the drug packaging machine of the present invention (solution 2) is the drug packaging machine of the solution 1, and has an internal discharge port for discharging the drug received from the drug feeder into the internal space by the upper drug collecting mechanism. It is characterized in that the viewing window faces one or both of the portions below the portion.

Further, the drug packaging machine of the present invention (solution 3) is the drug packaging machine of the solutions 1 and 2, wherein the window closing member is made of the same material as the plate-shaped lid portion, and the viewing window. It is characterized by being able to open.

In such a drug packaging machine of the present invention (solution 1), the upper drug collecting mechanism, which is a part of the drug collecting mechanism juxtaposed with the drug feeder, is a plurality of bodies in which the upper drug collecting mechanism runs vertically in parallel. If it is divided into two parts, it is assumed that at least one of them is arranged near the outer surface of the chemical storage part, and among such upper drug collection mechanisms near the outer surface, the inside is operated by removing or opening. By forming a relatively small viewing window for the plate-shaped lid part that exposes (that is, the upper drug collection mechanism is opened by operation), the relatively large plate-shaped lid part is enlarged. The inside of the upper drug collection mechanism can be easily visually confirmed if it is near the viewing window without any operation. Moreover, by providing a window closing member that can be smaller than the plate-shaped lid portion so that the viewing window can be closed, it is possible to easily and accurately prevent the inconvenience of the drug jumping out of the viewing window.
Therefore, according to the present invention, it is possible to realize a drug packaging machine capable of easily visually observing the inside of the upper drug collecting mechanism from a viewing window without opening the upper drug collecting mechanism widely.

Further, in the drug packaging machine of the present invention (solution 2), the drug discharged from the drug feeder is accepted by the upper drug collecting mechanism, and the drug is received from the internal discharge port of the upper drug collecting mechanism to the upper drug collecting mechanism. Based on the fact that when it is released into the internal space, it frequently falls while interfering with the vicinity of the internal discharge port and the lower part, the viewing window faces the main drug drop site, so that the peep can be seen. Even if the window is small, it is possible to accurately visually confirm the parts where problems such as dust adhesion and damage are likely to occur.
Therefore, according to the present invention, it is possible to realize a drug packaging machine that can easily and accurately visually check the inside of the upper drug collecting mechanism even if the viewing window is small.

Further, in the drug packaging machine of the present invention (Solution 3), the same material as the plate-shaped lid portion is used for the window closing member, so that the window closing member also has the durability of the plate-shaped lid portion. After preventing the window closing member from being damaged or soiled before the plate-shaped lid part by giving it characteristics such as resistance to dirt and dirt, the window closing member can not only close the viewing window but also open it. By making it possible, even if the window closing member is the same opaque as the plate-shaped lid portion, the inside of the upper drug collecting mechanism can be easily visually confirmed by opening a small viewing window.
Therefore, according to the present invention, it is possible to realize a drug packaging machine in which the inside of the upper drug collecting mechanism can be easily visually observed from a viewing window and it is not necessary to use a member having special physical characteristics as the material of the window closing member. Can be done.

The exemplified drug packaging machine 10 (see FIG. 1A) is a powdered tablet packaging machine capable of packaging a tablet and a powder individually or mixedly (see, for example, Patent Documents 4 to 6), and the drug is administered from the upper stage to the lower stage. It includes a storage unit 11, a drug hand-spreading device 13, a powder distribution and division device 14, a packaging device 15, and a control device (not shown). The drug storage unit 11 is equipped with a large number of drug feeders 12 capable of accommodating and sequentially discharging drugs such as tablets. According to the control of the control device, the drug feeder 12, the drug hand-spreading device 13, and the powder distribution splitting device 14 The chemicals in charge are sequentially discharged, and the packaging device 15 accepts the chemicals and separately encloses them in a packaging paper or the like (not shown).

Further, the drug packaging machine 10 (see FIGS. 1 (b) to 1 (d)) collects the drugs discharged from the drug discharging units 12, 13 and 14 while dropping them by their own weight, and collects them while dropping them by their own weight. It is equipped with a drug collecting mechanism 20 to be charged into. The drug collection mechanism 20 includes an upper drug collection mechanism 21 incorporated in the drug storage section 11 and a lower drug collection mechanism 26 arranged behind the drug hand-spreading device 13 below the upper drug collection mechanism 21, both of which are made of stainless steel as before. Made of steel.
Among them, the upper drug collecting mechanism 21 is located next to a large number of drug feeders 12 in order to receive and collect the drugs discharged from the large number of drug feeders 12.

Further, the drug packing machine 10 (see FIG. 1) has a small number of drug feeders 12 mounted (see, for example, Patent Documents 5 to 7), and the arrangement of the drug feeders 12 in the drug storage unit 11 is not three-dimensional. It remains two-dimensional (see, for example, Patent Documents 6 and 7).
Then, the upper drug collecting mechanism 21 is located behind the drug feeder 12 in the drug storage section 11 so that the cassette attachment / detachment work related to the drug feeder 12 which is frequently executed can be performed from the front (see FIG. 1A). It is located near the back surface (outer surface) of the chemical storage portion 11 (see FIGS. 1 (b) to 1 (d)).

Further, the upper drug collecting mechanism 21 is a relatively large one that is one size smaller than the drug storage portion 11 in order to cover the mounting range of the drug feeder 12, but is thin and flat in the front and rear. It is an inverted hollow body (see FIGS. 1 (b) to 1 (d)), and is attached to and detached from the main body portion 22 fixed to the rear of a large number of drug feeders 12 and the back thereof. It includes a plate-shaped lid portion 25. In this example, the plate-shaped lid portion 25 also serves as a portion of the back plate of the drug packaging machine 10 corresponding to the drug storage portion 11. Then, in the normal state, the plate-shaped lid portion 25 is attached to the main body portion 22 in order to surround the side peripheral surface portion of the space of the inner 24 which is the collection path of the falling drug (FIG. 1 (b), See Figure 2).

Moreover, the upper drug collecting mechanism 21 can remove the plate-shaped lid portion 25 from the main body portion 22 in order to largely expose the inside 24 at the time of cleaning or repair (FIG. 1). (D), see FIG. 4). Then, when the internal 24 is exposed, the main body portion 22 and the internal discharge port 23 appear to be alternately arranged vertically in a horizontal striped pattern corresponding to the multi-stage shelf of the drug feeder 12, and the lower end thereof is collected. Looking down from the opening for dropping and releasing the drug, the upper end of the lower drug collecting mechanism 26 can be seen (see FIG. 1 (d)). Since the internal discharge port 23 (see FIG. 4) connected to the drug discharge port of the drug feeder 12 discharges the drug received from the drug feeder 12 into the internal space (24), it is mounted in the drug storage section 11 for automatic discharge. A large number of them are provided in an arrangement corresponding to the possible drug feeder 12.

Further, in the drug packaging machine 10, only one viewing window 30 is formed in the plate-shaped lid portion 25 (see FIGS. 1 (c) and 3), and the window closing member 40 is mounted therein. (See Fig. 1 (b) and Fig. 2).
The viewing window 30 (see FIGS. 1 (c), 3 and 5 (b)) is mainly composed of an opening 31 capable of exposing a part of the inside 24 of the upper drug collecting mechanism 21, and is a window closing member. A rubbing portion 32 and an engaging portion 33 for easily attaching and detaching the 40 are also provided.

In the illustrated viewing window 30 (see FIG. 5B), the opening 31 is a vertically long small quadrangle, and the rubbing portion 32 is a protruding piece directed rearward from the left and right sides of the opening 31 by bending or the like. The engaging portion 33 is a notch in which the abutting portion 32 is cut diagonally downward.
In such a viewing window 30, the opening 31 faces both the internal discharge port 23 and the portion below the plate-shaped lid portion 25 when the plate-shaped lid portion 25 is attached to the main body portion 22. It is provided in such a place. Then, when the opening 31 is opened (see FIGS. 1 (c) and 3), the internal discharge port 23 and the main body portion 22 located beyond the opening 31 among the internal 24 of the upper drug collecting mechanism 21 are exposed. It has become.

The window closing member 40 (see FIG. 5A) is attached to the viewing window 30 to close the opening 31 (see FIGS. 1B and 2), and is similar to the plate-shaped lid portion 25. Since there is a possibility that chemicals may come into contact with the lid, it is made of stainless steel, which is the same material as the plate-shaped lid portion 25, and is opaque. The opening 31 of the viewing window 30 can be easily attached to and detached from the viewing window 30 so that the opening 31 of the viewing window 30 can be quickly opened when a person wants to look into the window 30.

Specifically (see FIG. 5A), the illustrated window closing member 40 has a flat plate-shaped closing portion 41 that fits snugly and smoothly into the opening 31 and a pair of rubbing portions bent at a right angle from the left and right sides thereof. Both the mating portions 42 and 42, the engaging portions 43 and 43 consisting of machine screws and the like projecting near the upper and lower ends of the mating portions 42, and the vertically long mating portions 42 and 42 at approximately the center. It includes a handle portion 44 connected to the members 42, 42.
Moreover, in the window closing member 40 and the viewing window 30 (see FIG. 5), in addition to the closing portion 41 corresponding to the opening 31, the outer surfaces of the rubbing portions 42 and 42 are the rubbing portions 32, respectively. In addition to corresponding to the inner surface of 32, the engaging portions 43, 43, 43, 43 correspond to the engaging portions 33, 33, 33, 33, respectively. For at least one of the four engaging portions 43, for example, the one on the upper right, the head is moved back and forth with respect to the rubbing portion 42 together with the screw portion by lightly pinching the head with a fingertip and rotating the shaft. Can be easily done.

The usage mode and operation of the drug packaging machine 10 of the first embodiment will be described with reference to the above-mentioned drawings.

In the normal state where the packaging operation is possible (see FIG. 1A), the plate-shaped lid portion 25 is attached to the back surface of the chemical storage portion 11 of the medicine packaging machine 10, and the viewing window of the plate-shaped lid portion 25 is attached. A window closing member 40 is mounted on the 30 (see FIGS. 1 (b) and 2). Then, when the inside 24 of the upper drug collecting mechanism 21 becomes dirty while repeating the packaging operation as in the conventional case, when the drug packaging machine 10 is stopped, the drug packaging machine 10 is used. Turning backward, the window closing member 40 is removed from the viewing window 30 of the plate-shaped lid portion 25. In this work, first, the engaging portion 43 on the upper right of the window closing member 40 is axially rotated with a fingertip or the like, the head of the engaging portion 43 is slightly separated from the rubbing portion 32 of the viewing window 30, and then the handle portion 44 is separated. By holding the window closing member 40 and pulling it backward or diagonally backward, it can be easily performed, so that even a user who is not a professional maintenance worker can easily perform it.

When the window closing member 40 is separated from the viewing window 30, an opening 31 appears (see FIGS. 1 (c) and 3), from which the inside 24 of the upper drug collecting mechanism 21 can be viewed. Although limited to the previous portion, the state of the main body portion 22 and the internal discharge port 23 can be visually confirmed. Then, if it is visually recognized that work such as cleaning the inside 24 of the upper drug collecting mechanism 21 is necessary, the work is performed by removing the plate-shaped lid portion 25 (FIGS. 1 (d) and 4). (See), the load is heavy for the user, so it is left to a professional maintenance worker.
On the other hand, when it is found by the above-mentioned visual inspection that the cleaning of the internal 24 is not necessary yet, the window closing member 40 is attached to the viewing window 30 to return to the original state, and the drug packaging machine 10 is restarted.

Here, when the window closing member 40 is attached to the viewing window 30 (see FIG. 5), first, the engaging portion 43 on the upper right is rotated about the axis to keep the head appropriately separated from the rubbing portion 42, and then. The handle portion 44 of the window closing member 40 is pinched, the closing portion 41 is slightly inserted between the rubbing portions 32 and 32 of the window 30, and the four engaging portions 43 are one-to-one with the openings of the four engaging portions 33. Push the window closing member 40 as far as it will go, and then push the window closing member 40 diagonally downward.
Then, all the engaging portions 43 are fitted tightly to the bottom of the corresponding engaging portions 33, and the closing portion 41 closes the opening 31 exactly, so that the engaging portion 43 on the upper right is turned in the opposite direction to the previous one. By rotating the shaft and bringing the head closer to the rubbing portion 42, the rubbing portion 32 in the vicinity of the engaging portion 33 on the upper right is sandwiched, and the window closing member 40 is fixed to the viewing window 30.

Alternatively (see FIG. 5), first, the head of the engaging portion 43 on the upper right is appropriately separated from the rubbing portion 42, then the handle portion 44 of the window closing member 40 is picked up and the lower end portion of the closing portion 41 is viewed through the window 30. Insert a little between the lower ends of the rubbing portions 32, 32, and align the lower engaging portions 43, 43 of the window closing member 40 with respect to the lower engaging portions 33, 33 of the viewing window 30. Then push it in, and then swing the upper part of the window closing member 40 toward the viewing window 30 with that as a fulcrum. Then, when the upper engaging portions 43, 43 reach the bottom of the upper engaging portions 33, 33, the closing portion 41 closes the opening 31 exactly, so that the head of the upper right engaging portion 43 is also rubbed. The window closing member 40 is fixed to the viewing window 30 by sandwiching the rubbing portion 32 in the vicinity of the engaging portion 33 on the upper right by approaching 42.

By opening and closing the viewing window 30 of the plate-shaped lid portion 25 with a small window closing member 40 in this way, the state of the inside 24 of the upper drug collecting mechanism 21 of the drug packaging machine 10 can be easily and quickly visually recognized by the user. can do.
Moreover, since the opening 31 of the viewing window 30 is much smaller than the plate-shaped lid portion 25, there is little leakage of chemicals and the like from the machine.

The specific configuration of Example 2 of the drug packaging machine of the present invention will be described with reference to the drawings. FIG. 6 is a perspective view of the chemical storage portion 11 as viewed from the rear upper left.
This drug packaging machine differs from that of Example 1 described above in that the number of viewing windows 30, which was one, is increased by one to two, and the number of window closing members 40 is also two. It has become. In the figure, the viewing window 30 is closed by the window closing member 40, and only the rubbing portion 32 is visible.
Since there are a plurality of viewing windows 30, the visual confirmation of the inside 24 of the upper drug collecting mechanism 21 may be performed by removing the window blocking member 40 from one of the viewing windows 30 as appropriate, but all the viewing windows 30. It is desirable to carefully remove the window closing member 40 from the window closing member 40.

In the above embodiment, the plate-shaped lid portion 25 of the upper drug collecting mechanism 21 also serves as the back plate (outer plate) of the chemical storage portion 11, but the plate-shaped lid portion 25 is the back plate. May be a separate body and may be arranged inside the back plate.
Further, in the above embodiment, the upper drug collecting mechanism 21 removes the plate-shaped lid portion 25 to expose the entire inside, but the plate-shaped lid portion 25 is limited to the removable one. However, it may be an opening / closing type by supporting a hinge or the like, and in that case, the upper drug collecting mechanism 21 opens the plate-shaped lid portion 25 to expose the inside 24. Further, the outer plate is not limited to the back plate, and may be either the left or right side plate or both side plates.

Further, in the above embodiment, the internal discharge port 23 and the internal discharge port 23 in which the portion of the internal 24 of the upper drug collection mechanism 21 facing the viewing window 30 discharges the discharged drug of the drug feeder 12 into the internal space. Although it covers both of the lower portion, the function of the viewing window 30 can be exhibited as it is even if one of them faces the other and the other does not face.
Further, the viewing window 30 is not limited to one or two as shown in the figure, and a large number of three or more may be formed. In any case, it is preferable that the viewing window 30 is installed at a position close to the lower end opening where the density at which the drug passes in the drop collection process tends to be high and is easy to see.

Further, in the above embodiment, the same opaque stainless steel as the plate-shaped lid portion 25 is used as the material of the window closing member 40 from the viewpoint of emphasizing durability, stain resistance, etc., but the viewing window 30 cannot be opened. From the viewpoint that the inside 24 can be visually confirmed, a transparent material such as plastic or tempered glass is preferable. If there is no dissatisfaction with workability, cost, durability, stain resistance, etc., a transparent plate-shaped lid portion 25 may be adopted.

Further, an openable door or the like may be attached to the side of the chemical storage portion 11 on which the chemical feeder 12 is mounted (see, for example, Patent Document 4).
An opening / closing shutter may be provided in place of or in addition to such a door (see, for example, Japanese Patent Application Laid-Open No. 2013-59567).

The drug packaging machine of the present invention can be expected to have a high effect by applying it to a single drug feeder before and after (see the above examples and Patent Documents 7 and 6), but its application is limited. However, it can also be applied to those in which a plurality of drug feeders are arranged in the front-rear direction (see, for example, Patent Document 5).
