Description

The present invention relates to a drug storage device and a drug storage device such as a drug shelf, a dispensing table, and a storage cabinet for medical equipment. The present invention relates to a medicines storage device which has a plurality of medicines from which medicines can be selectively taken out based on medicines delivery information.

If the object of storage is not limited to medicines, a typical example of a storage cabinet with a separate storage function is a general-purpose locker or equipment storage unit in which the storage part is divided into many compartments and each compartment has a door. Goods stand etc. are mentioned.
On the other hand, when the object to be stored is chemicals, in addition to storing chemicals such as ampules in a large number of cassettes (storage containers) and storing them separately, in addition to selecting the chemicals in the cassettes, the opening operation is performed. A drug storage device has been developed that can automatically perform up to.

This drug storage device (see, for example, Patent Documents 1 to 3) includes a large number of storage containers that store drugs, a storage section that holds the storage containers arranged vertically and horizontally so that they can be drawn forward, and each of the storage containers. It consists of a motor installed in the rear and an extrusion mechanism equipped with an eccentric cam and a link mechanism attached to its rotating shaft. and a drive mechanism.

Some of them are equipped with a shutter that can be stored at the top of the housing (shutter for opening and closing the front of the cabinet, hereinafter simply referred to as the opening and closing shutter) from the viewpoint of security and maintenance when not in use. There is one that allows the front surface to be opened and closed (see Patent Document 1, for example).
In addition, regarding the opening drive mechanism that contributes to the improvement of convenience, an eccentric cam is adopted in the pushing mechanism to reduce costs (see, for example, Patent Document 2), and a link mechanism is adopted in the pushing mechanism to increase the pushing distance of the storage container. (see, for example, Patent Document 3), and various improvements have been made.

Furthermore, a plurality of compartmentalized shelves capable of holding a large number of medicines side by side, a shelf frame in which the compartmentalized shelves can be individually pulled out forward, and a shelf portion disposed under the shelf frame are provided. A drug shelf has also been developed that has a pedestal that supports it from below (see, for example, Patent Document 4).
In the drug shelf, a horizontal plate-like placement receiving member is incorporated in the upper end portion of the base in such a manner that it can be pulled forward or pushed in and out and can be advanced and retracted. is provided with means for stabilizing the pressed state, such as a so-called magnet catch or latch mechanism, in order to maintain the state when not in use.

Among such conventional drug storage devices, in the type of drug storage device in which the storage container is advanced by an eccentric cam or the like (see the above-mentioned Patent Documents 1 and 2), the advance distance of the storage container is short, so opening and closing is difficult. Even if the storage container is inadvertently driven forward when the shutter is closed, the possibility of the storage container colliding with the open/close shutter is small, and the storage container and the pushing mechanism are relatively rigid, so even if the storage container opens and closes. Even if the shutter collides with the shutter, there is no need to fear or worry that an undesirable situation such as breakage of members of the storage container or the push-out mechanism will occur.

On the other hand, in a medicine storage device of the type in which a link mechanism is employed in the push mechanism to greatly extend the forward movement distance of the container (see the above-mentioned Patent Document 3), the forward movement distance of the container is long and the push mechanism is large. Since the members are relatively complicated and fragile, if the storage container is inadvertently driven forward while the open/close shutter is closed, the storage container will certainly collide with the open/close shutter, and the reaction force will cause the storage container to move. It is very likely that it will get caught in the pusher mechanism through and damage the linkage there. For this reason, this type of drug container does not have an opening/closing shutter.

However, as the latter medicine storage device (see Patent Document 3 mentioned above) with a large advance distance becomes popular, the former medicine storage device with an opening and closing shutter (see Patent Documents 1 and 2 mentioned above) is used. We have received requests from users who have used the drug storage device (see Patent Document 3 mentioned above) to attach an opening and closing shutter to the drug storage device.
However, regarding the latter drug storage device (see Patent Document 3 mentioned above), in which the forward movement distance of the storage container is extended at the expense of the rigidity of the extrusion mechanism, an opening and closing shutter is simply attached to the current machine. If only this countermeasure is taken, the link mechanism of the pushing mechanism may be damaged as described above, and the front end portion of the storage container may be damaged, so the countermeasure is insufficient.

In addition to installing a shutter, it is also possible to extend the front and back length of the housing to increase the distance between the rear surface of the opening and closing shutter and the front end of the storage container. This is not preferable because the storage efficiency is lowered because the number of stored items does not increase. On the other hand, from the viewpoint of cost, durability, etc., it is desired that the opening and closing shutters to be attached should be manually operated rather than electrically operated.
Therefore, it is a first technical problem to realize a drug storage device in which forward collision of the storage container against the shutter can be suppressed even if a manual opening/closing shutter is attached.

Furthermore, like a drug shelf provided with a drawable shelf frame for holding drugs and a base underneath it (see the above-mentioned Patent Document 4), it is possible to pull out forward or push back backward. Recently, there have been requests for attachment of a horizontal plate-shaped placement receiving member that can be used for the drug storage device.
However, in the medicine storage device, unlike the medicine shelf with a pedestal portion, the frequency of taking out medicines, etc. differs greatly between the compartmentalized shelf above the pedestal member and the pedestal portion below the pedestal member. Medicines in the lower storage container may also be taken out as frequently as chemicals in the storage container above the placement receiving member.

Therefore, if the draw-out mode of the placement receiving member is a two-way alternative, whether it is put out or put in, it is necessary to visually confirm whether or not the storage container below the pulled-out placement receiving member is to be taken out. It is difficult to dispel the concern that a situation where the placement receiving member cannot be utilized or a situation where it is difficult to use the placement receiving member may frequently occur.
Therefore, the second technical problem is to enable the dispensing operator or the like to select the mode of use of the placement receiving member when attaching the placement receiving member to the medicines storage device.

The medicine storage device of the present invention (Solution 1) was invented to solve such problems,
A large number of storage containers for storing chemicals, a storage section holding the storage containers in a state in which the storage containers can be individually drawn forward, and a large number of opening drive mechanisms disposed behind the storage containers, and It is possible to store the housing inside the housing by pushing the stored housing toward the end of the storage section, and the front surface of the storage section is released when stored, but the front surface of the storage section is opened when the storage section is pulled out. A device comprising an open/close shutter, wherein the opening drive mechanism includes a drive unit having an electric motor; a push-out mechanism that, when driven by the drive unit, pushes forward the storage container at the installation destination; When driven by the drive unit, it disengages from the storage container prior to being pushed by the push-out mechanism, allowing the storage container to be drawn forward, but when the storage container is pushed backward, it engages with the storage container and stores the storage container. A drug storage device comprising a lock mechanism that prevents forward withdrawal of the container,
an open/close detection mechanism for detecting whether or not the opening/closing shutter is housed in the housing until the front surface of the storage section is fully opened is incorporated in a side end of the housing;
When it is not possible to confirm that the opening/closing shutter is housed in the housing based on detection by the opening/closing detection mechanism, driving of the pushing mechanism by the driving unit is inhibited. characterized by

Further, the medicines storage device of the present invention (solution 2) is the medicines storage device of the solution 1, wherein the open/close detection mechanism is a shutter storage portion for storing the open/close shutter in the housing. The detection state is switched when the front end of the open/close shutter is located between the shutter storage section and the storage section when the open/close shutter is pulled out. , characterized in that

Further, the medicines storage device of the present invention (solution 3) is the medicines storage device of the solution 2, wherein the open/close detection mechanism includes a mechanical switch for switching a detection signal, and the shutter storage unit. A response member that swings in accordance with contact and separation with the opening/closing shutter that moves in and out, a transmission mechanism that transmits the swinging motion of the response member to the mechanical switch, and the response member that is attached to the side that contacts the opening/closing shutter. and a transmission portion biasing member that biases the transmission mechanism in a direction in which the switching state of the mechanical switch becomes the non-detection side of the open/close shutter. and a cushioning member that relieves the condition by elastic deformation.

Further, the medicines storage device of the present invention (solution means 4) is the medicines storage device of the solution means 3, wherein the reaction member, the transmission mechanism and the mechanical switch are vertically arranged. It is characterized by

Further, the medicines storage device of the present invention (solution 5) is the medicines storage device of the above solutions 1 to 4, which is a horizontal plate-like placement receiver that can be pulled out forward and pushed back backward. A member is incorporated in the middle position of the storage section, and the front-rear movement of the placement receiving member is restrained at a forward pull-out position, a rearward push-back position, and an intermediate position therebetween. characterized by

In addition, the medicines storage device of the present invention (solution 6) is the medicines storage device of the above solutions 1 to 4, which is a horizontal plate-shaped placement receiver that can be pulled out forward and pushed back backward. A member is incorporated in the middle position of the storage part, and a rear wheel is attached to the rear part of the placement receiving member, and a front wheel is attached to the rear of the center but in front of the rear wheel. An upper guide member that guides the longitudinal movement of the wheel from above and a lower guide member that guides the longitudinal movement of the front wheel from below are arranged vertically facing each other at a portion where the placement receiving member is incorporated in the storage section,
One or both of the upper guide member and the lower guide member has a notch in which a part of the wheel to be guided out of the front wheel and the rear wheel is fitted to prevent smooth rolling of the wheel. , and three or more are formed dispersedly in the front and rear.

Further, the medicines storage device of the present invention (solution means 7) is the medicines storage device of the solution means 6, wherein the slide member slides on the upper surface of the placement receiving member and moves backward. A rearward movement restraining portion for restraining rearward movement of the sliding member is provided at a rear portion of an upper surface of the placement receiving member.

Further, the medicines storage device of the present invention (solution means 8) is the medicines storage device of the above solution means 1 to 7, comprising means for communicating with a host device, wherein the open/close shutter is the housing. When the dispensing instruction is received from the host device when it cannot be confirmed based on the detection of the open/close detection mechanism that the drug is stored in the storage unit, a reply to the effect that the dispensing instruction cannot be followed is sent to the host device. It is characterized by

In such a drug storage device of the present invention (solution 1), an opening/closing detection mechanism is also provided when the opening/closing shutter is mounted, and the opening/closing shutter is stored in the housing until the front surface of the storage section is released. In addition to detecting whether or not the opening/closing shutter is in the housing, the driving of the push-out mechanism is inhibited when it is not possible to confirm that the opening/closing shutter has been stored in the housing and that the front surface of the storage section has been released. Collision between the storage container and the open/close shutter can be reliably avoided regardless of the size of the advance distance.

In addition, since the front-rear width and depth of a device that stores a variety of chemicals that can be taken out individually are generally narrower than the width and left-right width, the built-in open/close detection mechanism in the side end of the housing makes it possible to detect open/close detection means. Even if the size of the device is increased by mounting the , the increase in the occupied area is suppressed to a small extent. Furthermore, if the opening/closing detection means can be housed inside the side plate, the enlargement of the device size can be completely avoided.
Therefore, according to the present invention, it is possible to realize a drug storage device in which the advance collision of the storage container against the shutter can be suppressed even if a manual opening/closing shutter is attached, and the first technical problem can be solved. In addition, it is possible to avoid or suppress a decrease in storage efficiency.

Further, in the medicine storage device of the present invention (Solution 2), by placing the opening/closing detection mechanism near the opening/closing shutter storage section, the response of the opening/closing detection mechanism performed when the opening/closing shutter is closed is minimized. can be completed at the initial movement stage, so even if the opening/closing shutter is manually operated and its moving speed tends to fluctuate, the closing operation can be detected quickly and stably.
Moreover, even if the open/close detection mechanism is of a mechanical type, contact is made in the slow initial movement stage, so there is the advantage that the impact applied to the open/close detection mechanism can be reduced.

Furthermore, in the medicine storage device of the present invention (Solution 3), when embodying the opening/closing detection mechanism, a mechanical switch that can be expected to operate more stably than optical detection, which is said to be vulnerable to dust stains, is used. Instead of operating the mechanical switch directly with the opening/closing shutter, the direct impact on the mechanical switch is mitigated by intervening a reaction member that directly contacts and leaves the opening/closing shutter. In addition to an appropriate biasing member, a cushioning member is also provided in the power transmission path leading to the switch to mitigate even the indirect impact. Even if the mechanical switch is exposed to an impact, the impact on the mechanical switch is sufficiently reduced and mitigated, so that the open/close detection mechanism can operate stably for a long period of time.

In the medicine storage device of the present invention (solution 4), the open/close detection mechanism is small in plan view by vertically arranging the response member, the transmission mechanism, and the mechanical switch that constitute the open/close detection mechanism. Since the opening/closing detection mechanism can be incorporated in a narrow space such as a narrow gap along the moving path of the opening/closing shutter, it is possible to avoid or suppress an undesired increase in the area occupied by the device.

Further, in the medicine storage device of the present invention (solution 5), the forward and rearward movement of the placement receiving member is restrained at the forward pull-out position, the backward push-back position, and the intermediate position between them. As a result, in addition to the rearmost push-back position and the frontmost pulled-out position, the so-called stable stop positions corresponding to intermediate states between the fixed state and the freely movable state of the placement receiving member include: There will also be an intermediate position located between those two positions.
Therefore, according to the present invention, when using the placement receiving member attached to the medicine storage device, it is determined whether the member is pushed into the storage portion or pulled out largely from the storage portion. The second technical problem is solved in addition to the first technical problem because the stable stop position can be easily selected by pulling out the member halfway from the storage part.

In the medicine storage device of the present invention (solution means 6), since the front wheels are attached to the rear portion of the placement receiving member, when the front wheels are placed on the lower guide member, the placement receiving member Although the rear portion tries to rise, the rear wheel is restrained from rising by the upper guide member, so that the placement receiving member maintains its lateral posture. Then, when the placement receiving member is moved back and forth and a part of the wheel is fitted in one of the plurality of notches, the placement receiving member is stabilized there, so that the placement receiving member can be brought to a stable stop position. In addition to the rearmost push-back position and the frontmost pulled-out position, there is also a midway position.

Such a placement receiving member located in the middle of the storage container makes it easy to see the storage container below while maintaining the function of temporarily holding the medicine taken out from the storage container to some extent. Such diversification of drawer modes widens the range of utilization of the placement receiving member. When the front end of the support member is lifted slightly, the engagement of the wheel with the notch is released, so that the support member is not fixed but stably stopped. There is no inconvenience in moving.
Therefore, according to the present invention, when using the placement receiving member attached to the medicine storage device, it is determined whether the member is pushed into the storage portion or pulled out largely from the storage portion. The second technical problem can be solved in addition to the first technical problem, because it is possible to freely choose whether or not to pull out the member halfway from the storage part.

Further, in the medicines storage device of the present invention (solution means 7), the front end of the placement receiving member is moved prior to moving the placement receiving member that is stably stopped by fitting the wheel into the notch. When the unit is slightly lifted or the placement receiving member is further pulled forward, placed items such as medicines and paper already placed on the placement receiving member may easily slide or roll backwards. However, even if such sliding or rolling occurs, the rearward movement of the placed object is restrained by abutment with the rearward movement restraining portion, so that the placed object moves from behind the placement receiving member into the chamber. It is possible to prevent the occurrence of an undesired situation of falling into.

In addition, in the medicine storage device of the present invention (solution means 8), when the open/close shutter is closed, even if a dispensing instruction is sent from the host device, the operation to follow the dispensing instruction cannot be performed immediately. In addition, by sending a reply to that effect back to the host device, it is possible to widely inform the need to open the shutter of the corresponding chemical storage device, and to select another device as the chemical storage device to be used. It will also contribute to the decision to fix it.

The medicines storage device 10 (see FIGS. 1(a) to 1(d)) comprises a vertically long rectangular parallelepiped housing 11 close to the height of the user's back, and a shutter storage unit 13 is provided at the top of the housing 11. (see FIG. 1(b)), and the lower part of the housing 11 is equipped with an electrical component (not shown). are assigned (see FIGS. 1(b) to (d)), and when the open/close shutter 12 is pulled down from the shutter housing portion 13, the front surface of the storage portion 14 is closed (see FIG. 1(a) ). An open/close detection mechanism 30 for detecting the open/closed state of the storage section 14 is also incorporated in the housing 11 in the vicinity of the shutter entrance/exit of the shutter storage section 13 (FIGS. 1A and 1B). Right above the storage section 14).

A large number of storage containers 20 arranged vertically and horizontally are held in the storage part 14 in such a manner that they can be individually drawn forward, and when the opening/closing shutter 12 is opened, the front ends of the storage containers 20 appear. (See FIG. 1(b)). The storage container 20 is formed of a box that is elongated in the front-rear direction and has an open upper surface so that drugs such as medicines and medical materials can be manually taken in and out from the open upper surface. A placement receiving member 50 that can be drawn forward is also incorporated in a part slightly lower in the middle of the storage section 14 (see FIGS. 1(b) to 1(d)). The placement receiving member 50 is in the shape of a horizontal plate with a substantially flat upper surface, and as will be described in detail later, the placement receiving member 50 is pushed into the storage section 14 (see FIG. 1(b)) and is large from the storage section 14. It is stabilized in the pulled out state (see FIG. 1(c)) and the intermediate state (see FIG. 1(d)).

The open/close shutter 12 (see FIG. 1(a)) can be a general one in which horizontally long rectangular members are connected in a bellows shape, and the exposed front end (lower end in FIG. 1(a)) is covered with a hand. 1(a) toward the shutter housing portion 13 (upward in FIG. 1(a)), the shutter is guided by the guide rail and pushed into the shutter housing portion 13 (see FIG. 1(b)). . 1 (b) to (d), it is hidden just above the front surface of the compartment 14). It unfolds and covers the front surface of the housing 11 according to the guidance of the guide rails on the left and right ends of the front portion (see FIG. 1(a)). It should be noted that the illustration is omitted because it is not essential, but it is also possible to lock it.

Since the storage container 20 may be a known product (see, for example, Patent Document 3), any large or small object (see FIGS. 1(b) to 1(d)) can be stored in the drawer frame 25 corresponding to the size. (See FIG. 2(a)), it can be pushed forward by the opening drive mechanism 21 (see FIG. 2(b)), further forward manually pulled out, and rearward manually pushed back. ing. On the left side of the front end of the drawer frame 25 (see FIG. 2), a lighting unit 26 mainly composed of, for example, color LEDs is attached, and is turned on and off under the control of a control unit 40 (see FIG. 4). It is also designed to An opening driving mechanism 21 for pushing the storage container 20 is provided inside the drawer frame 25 at a portion behind the storage container 20 (see FIG. 2).

The open drive mechanism 21 may also be a known product (see Patent Document 3, for example). A push-out mechanism 22 comprising a link mechanism and driven by the above-mentioned drive section to push forward the storage container 20 at the installation destination, and a push-out mechanism 22 together with the push-out mechanism 22 when driven by the above-mentioned drive section. Prior to the boosting operation, the lock disengages from the storage container 20 to be driven and permits the storage container 20 to be drawn forward, but when the storage container 20 is pushed backward, it is associated with the storage container 20 to prevent the storage container 20 from being drawn forward. A mechanism 23 is provided.

The opening/closing detection mechanism 30 (see FIG. 3) is for detecting whether or not the open/close shutter 12 is housed in the housing 11 until the front surface of the compartment 14 is fully opened. It is installed near the doorway of the open/close shutter 12 and does not hinder the entry/exit of the open/close shutter 12.例文帳に追加In this example (see FIG. 1(b)), the open/close detection mechanism 30 is attached to a position immediately inward of the left side plate of the housing 11, and is positioned near the front and near the bottom of the left side surface of the shutter housing portion 13. When the front end of the opening/closing shutter 12 (the end on the leading side when it is pulled out) is positioned between the shutter accommodating portion 13 and the storage portion 14, as will be described in detail later. The detection state of the open/close detection mechanism 30 can be switched.

This open/close detection mechanism 30 (see FIG. 3) uses a general mechanical switch 31 in which a signal output terminal 31a and an operating portion 31c are incorporated in a switch body 31b (see FIG. 3(b)). If the operation portion 31c of the mechanical switch 31 is directly operated by the opening/closing shutter 12, the operation portion 31c and the like are likely to be damaged. In addition to the reaction member 34 attached near the upper end of the opening/closing shutter 12 and acting for contact/separation with the opening/closing shutter 12, transmission mechanisms 36 to 38 for transmitting the swinging motion of the reaction member 34 to the mechanical switch 31 are also attached to the holding frame 32. (see FIGS. 3(c) and 3(d)).

The transmission mechanisms 36 to 38 are a combination of a swing member 36, a buffer member 37, and a leaf spring 38. The leaf spring 38 is arranged above the mechanical switch 31 side, and the reaction portion biasing member 35 side A rocking member 36 is arranged below, and the plate spring 38 and the operating portion 31c of the mechanical switch 31 transmit power by contact and separation, and the plate spring 38 and the rocking member 36 are in direct contact. , and the swinging member 36 and the reaction member 34 perform transmission via the cushioning member 37 . The plate spring 38 also serves as a transmission portion biasing member. Coil springs are employed for the responsive portion biasing member 35 and the buffer member 37 among them. The opening/closing detection mechanism 30 has the mechanical switch 31, the transmission mechanisms 36 to 38, and the reaction member 34, which are the main members thereof, arranged vertically. Since it fits inside the part, it is not necessary to increase the width of the housing 11 .

The response member 34 is made of a vertically elongated plate-like member that swings according to contact and separation with the opening/closing shutter 12 that moves in and out of the shutter housing portion 13 . protruding toward In addition, the reaction member 34 is supported by a supporting shaft 33 at a portion slightly above the center so that it can swing. It is biased in the swinging direction. In other words, the contact/separation portion 34a of the reaction member 34 is adapted to bias the reaction portion biasing member 35 in the direction in which the contact/separation portion 34a contacts the opening/closing shutter 12. As shown in FIG.

Therefore, when the opening/closing shutter 12 is housed in the shutter housing portion 13 (see FIG. 3(c)), the contact/separation portion 34a protrudes below the opening/closing shutter 12 without interfering with the opening/closing shutter 12. As shown in FIG. On the other hand, when the open/close shutter 12 is pulled out from the shutter housing portion 13 and the tip of the open/close shutter 12 is lowered to the contact/separate portion 34a (see FIG. 3(d)), the contact/separate portion 34a is pulled out of the open/close shutter 12. Since it is pushed by the front side end portion 12 a , the reaction member 34 swings around the support shaft 33 against the biasing force of the reaction portion biasing member 35 .

Further, in the opening/closing detection mechanism 30, when the reaction member 34 swings as described above (see FIGS. 3(c) and 3(d)), the buffer member 37 having one end 37a attached to the reaction member 34 extends. The swinging member 36 to which the other end 37b of the cushioning member 37 is attached also swings around the support shaft 33, but the transmission of motion from the responding member 34 to the swinging member 36 causes the stretchable cushioning member 37 to move. Therefore, when the opening/closing shutter 12 is pulled out, if the contact between the leading edge 12a and the contact/separate portion 34a of the reaction member 34 is gentle, it will swing even if it is abrupt. The rocking motion of member 36 is designed to be fairly gentle. Such a buffer member 37 relaxes the transmission state by elastic deformation.

Further, in the opening/closing detection mechanism 30, when the swinging member 36 swings as described above (see FIGS. 3(c) and 3(d)), the lower end of the leaf spring 38, which is also the non-fixed end and the free end, Pushed by the upper end of the swinging member 36, it moves toward the mechanical switch 31, and along with this movement, the intermediate portion of the plate spring 38, which has been in contact with the holding frame 32, moves away from the holding frame 32 and the mechanical switch 31 is operated. It approaches the portion 31c, further reaches the operating portion 31c, and finally pushes the operating portion 31c into the switch body 31b to operate the mechanical switch 31 (see FIG. 3(d)).

Although a detailed description that will be repeated will be omitted, when the open/close shutter 12 is pushed back from the front surface of the compartment 14 to the shutter housing portion 13, the open/close detection mechanism 30 operates in the reverse order to that described above. 30 can stably and accurately detect the open state of the front surface of the storage section 14 . At that time, the reaction member 34 is biased by the reaction portion biasing member 35 , but the swinging member 36 is mainly biased by the repulsive force of the plate spring 38 . It can be said that it also serves as a transmission portion biasing member that biases the transmission mechanisms 36 to 38 in a direction where the state is the non-detection side of the open/close shutter 12 .

Furthermore, the medicine storage device 10 is also provided with a control unit 40 mainly composed of a microcomputer on the inner bottom of the housing 11 (see FIG. 4). In addition to the operation control, it is designed to input a detection signal of the open/closed state of the mechanical switch 31 and the like.
The control unit 40 can transmit and receive various data to and from a superordinate group control device 200, which is separate from the medicine storage device 10, by communication means such as a LAN (Local Area Network). Only the containers 20a and 20b to be dispensed are pushed out by the opening drive mechanism 21 based on the received dispensing instruction data.

However, the execution control of the push-out operation as described above by the control unit 40 is based on the detection of the open/close detection mechanism 30 by the control unit 40 that the open/close shutter 12 is stored in the shutter storage unit 13 of the housing 11. Only when you can. When the control unit 40 cannot confirm that the opening/closing shutter 12 is housed in the shutter housing portion 13 of the housing 11 based on the detection of the opening/closing detection mechanism 30, the housing by the push mechanism 22 of the opening drive mechanism 21 is performed. By not executing the control for pushing out the container 20, the drive of the pushing mechanism 22 with respect to the storage container 20 is suppressed. A reply to the effect that the dispensing instructions cannot be followed because the unit 14 is closed is also sent to the host device 200 .

The group management device 200 is composed of a computer equipped with a display device 201 such as a panel display, and when receiving a reply from the medicine storage device 10 indicating that dispensing instructions cannot be followed, it opens and closes the opening/closing shutter 12 of the corresponding medicine storage device 10. An instruction for the operator to the effect of opening is displayed on the display 201 . This dispensing system also includes a dispensing server 100 that receives and collects prescription data based on prescriptions from an external prescription ordering system or the like. Device information related to a large number of dispensing devices including the device 10 is held as data, and a drug master summarizing information related to a large number of drugs to be handled is also held as data.

This dispensing server 100 is also equipped with a display device 101 such as a panel display. The display 101 displays an instruction for the operator to the effect that the door is to be opened. Although only one group management apparatus 200 is shown in FIG. 4, generally in a large-scale system, a plurality of group management apparatuses 200 are installed, and various devices such as the drug storage device 10 and a drug packaging machine (not shown) are installed. A large number of dispensing devices are installed. In a small-scale system, the number of dispensing devices installed is small, and the group control device 200 and the like may be omitted.

Returning to the description of the configuration of the medicines storage device 10 itself, the placement receiving member 50 (see FIG. 1), which has already been outlined, specifically (see FIGS. 5 and 6A), is located in the middle of the storage unit 14. Movable members belonging to the built-in mounting mechanisms 50 & 60 include a substantially rectangular horizontal plate 51 with a flat upper surface, and an elongated rearward movement restraining portion 52 erected at the rear portion of the upper surface and extending to the left and right for nearly the entire width. a rear wheel 54 provided at the lower end near the rear end of both left and right sides of the horizontal plate 51; Equipped with front wheels 53. The front wheels 53 are provided at a position slightly lower than the rear wheels 54 .

The rearward movement restraining portion 52 of the placement receiving member 50 is for contacting the sliding member sliding on the upper surface of the horizontal plate 51 and moving rearward to restrain the rearward movement of the sliding member. However, since the upper end portion of the backward movement restraining portion 52 is bent forward (see FIG. 6(a)), even if a thin sheet of paper such as a dispensing instruction sheet floats up and moves backward, , the trailing edge of the paper slips under the upper end of the backward movement restraining portion 52 and collides with the rising portion of the backward movement restraining portion 52, and the upward movement is restrained by the upper end of the backward movement restraining portion 52. Not only thin objects such as paper but also thin objects can be held on the placement receiving member 50 with a high degree of accuracy.

Of the placing mechanisms 50 & 60, the guide mechanism 60 for movably holding the placement receiving member 50 back and forth (see FIGS. 5, 6B, and 6C) is a straight elongated member having a U-shaped cross section. A long plate-shaped upper guide member 61 corresponding to the upper horizontal line of the U-shape and a long plate-shaped lower guide member 62 corresponding to the lower horizontal line of the U-shape are opposed in parallel. It stretches straight forward and backward. The lower guide member 62 has a rolling suppression notch 65 formed near the front end, a rolling suppression notch 64 formed behind it, and further behind it but forward of the rear end. The formed rolling suppression notch 63 penetrates the lower guide member 62, but the upper guide member 61 does not have such a notch. The rolling suppression cutouts 63 to 65 may be small enough to slightly fit the lowermost portion of the front wheel 53 of the placement receiving member 50, or may be a recess that does not penetrate.

The mounting mechanisms 50 and 60 (see FIGS. 5 and 6(d) to (f)) are a combination of the mounting receiving member 50 and the guide mechanism 60, and are arranged inside the both side surfaces of the housing 11 so as to face each other. It is assembled by inserting the placement receiving member 50 between a pair of attached guide mechanisms 60, 60. As shown in FIG.
When inserting the guide mechanism 60, the rear wheel 54 and the front wheel 53 of the guide mechanism 60 are loosely inserted between the upper guide member 61 and the lower guide member 62 of the guide mechanism 60, and the placement receiving member 50 is pushed all the way into the guide mechanism 60. The mounting mechanisms 50 and 60 are simply assembled (see FIGS. 5(a) and 6(d)).

5(a) to (c) and FIGS. 6(d) to (f)), the front wheel 53 is incorporated in a portion behind the center of gravity of the placement receiving member 50. The front wheel 53 rides on the lower guide member 62 of the guide mechanism 60 and is guided from below in forward and backward movement, while the rear wheel 54 contacts the upper guide member 61 of the guide mechanism 60 from below and is guided in forward and backward movement from above. become a thing. In addition, since the front wheel 53 of the placement receiving member 50 can be slightly fitted in the rolling suppression notches 63 to 65 as described above, when the guide mechanism 60 is lightly moved back and forth, the front wheel 53 will be pushed into the rolling suppression notches 63 to 65. When it reaches the point 65, the front wheels 53 are prevented from rolling smoothly and stop. When the front end of 50 is slightly lifted and pushed/pulled, it moves again.
In such a mounting mechanism 50 & 60, the front-rear movement of the mounting receiving member 50 is restrained at a forwardly drawn-out position, a rearwardly pushed-back position, and an intermediate position therebetween.

The mode of use and operation of the drug storage device of the first embodiment will be described with reference to the drawings.
Since the overall usage and operation of the medicine storage device 10 are the same as those known, detailed description thereof will be omitted, and the usage and operation of the opening/closing shutter 12 and the placement receiving member 50 will be described here. I will elaborate.

Even if it is outside or within the time of dispensing work, when it is known that the medicine storage device 10 will not be used for dispensing, such as when the work is completed, or when it is necessary from the viewpoint of security and operation, medicines are stored as much as possible. Before stopping the supply of operating power to the storage device 10, or while the power supply is continued, the open/close shutter 12 is manually pulled out from the shutter storage portion 13 and lowered to the front surface of the storage portion 14 (see FIG. 1A). ). Then, in the drug storage device 10, when the tip of the opening/closing shutter 12 comes out of the opening/closing detection mechanism 30 and approaches the upper end of the storage section 14, the opening/closing detection mechanism 30 interfering with the opening/closing shutter 12 quickly causes the opening/closing shutter 12 to be opened. The drawer is detected (see FIG. 3(d)), and the controller 40 recognizes it.

However, if the control unit 40 of the medicines storage device 10 has stopped operating when the front surface of the storage unit 14 is closed or about to be closed by the open/close shutter 12, the medicines from the group management device 200 will be Since data cannot be sent to the storage device 10, the dispensing instruction does not reach the medicines storage device 10, so the drive control of the opening drive mechanism 21 by the control unit 40 is not performed. Therefore, the undesired situation in which the storage container 20 automatically advances and collides with the open/close shutter 12 does not occur.
Further, the group management device 200 and the dispensing server 100 can grasp the operation stop state of the medicines storage device 10 based on the detection of the communication disabled state with the medicines storage device 10 .

On the other hand, when the control unit 40 of the medicine storage device 10 continues to operate, the control unit 40 suppresses the operation control of the opening drive mechanism 21 unless the open/close shutter 12 is fully opened. 20 advances and collides with the open/close shutter 12, which is undesirable. Moreover, when the dispensing instruction data is transmitted from the group management device 200 to the medicines storage device 10, a reply to the effect that the dispensing instruction cannot be followed is sent from the medicines storage device 10 to the group management device 200, and the group management data A transfer is also made from the device 200 to the dispensing server 100 . Then, the host devices 200 and 100 display on the displays 201 and 101 that the storage section 14 of the medicine storage device 10 is closed.
Therefore, the dispensing operator can quickly grasp the situation.

When the opening/closing shutter 12 is opened while the control unit 40 of the medicines storage device 10 is operating, or when the control unit 40 operates while the opening/closing shutter 12 is open, in short, the medicines storage device 10 is normal. When the opening/closing shutter 12 is open (see FIG. 1(b)), when the medicines storage device 10 receives a dispensing instruction from the group control device 200, the medicines storage device responds to the dispensing instruction. 10, storage containers 20a and 20b containing medicines to be dispensed are pushed forward by opening drive mechanism 21, and the front ends of storage containers 20a and 20b move forward from chamber 14. It sticks out (see FIGS. 1(c), (d), and FIG. 2(b)). Since the storage containers 20a and 20b are unlocked by the lock mechanism 23, when the storage containers 20a and 20b are further pulled manually, the storage containers 20b protrude greatly forward from the storage section 14, and the interior of the containers can be seen to the rear. can be taken out easily.

If you want to temporarily store the medicines you have taken out, containers such as small boxes containing them, and papers such as dispensing instructions, there is a suitable place nearby such as a desk or workbench. When it is not there, put your hand on the front end of the placement receiving member 50 stored in the housing 11 (see FIG. 1(b)), lift the front end slightly and pull it forward, and then pull the front wheels of the placement receiving member 50. 53 reaches the foremost rolling suppression notch 65 of the guide mechanism 60, when the hand is released from the placement receiving member 50, the placement receiving member 50 stabilizes there (FIGS. 1(c) and 6(f)). ), the wide upper surface of the placement receiving member 50 can be used as a temporary storage area during dispensing work. Since the rearward movement restraining portion 52 is provided at the rear portion of the upper surface of the placement receiving member 50, even if not only medicines but also dispensing instruction sheets, writing instruments, etc. are placed, there is no fear of them falling backward, and safety is ensured. You can use it with confidence.

However, such a large withdrawal action of the placement receiving member 50 may be caused when the storage container 20 positioned below the placement receiving member 50 is included in the drug take-out target. Therefore, the front wheels 53 of the placement receiving member 50 are guided by the guide mechanism when the placement receiving member 50 is pulled out, or when the placement receiving member 50 is pulled out too much and is pushed back. When the placement receiving member 50 is released when it reaches the rolling suppression notch 64 at the intermediate position of 60, the placement receiving member 50 is stabilized there as well (see FIGS. 1(d) and 6(e)). . Therefore, the degree to which visual observation of the storage containers 20a and 20b below is hindered by the placement receiving member 50 is small, and the upper surface of the placement receiving member 50 used as a storage space is narrowed, but is secured as such. Therefore, it is possible to moderately enjoy the effects of both mechanisms.

The medicines storage device of the present invention was developed mainly for the purpose of preventing the collision of the storage container against the manual opening/closing shutter when the storage container automatically advances. A type of device that does not collide with is not useless, although there is also a trade-off with cost. For example, since the lock of a storage container that has moved forward automatically is released, a situation can occur in which the storage container advances further due to shaking caused by an earthquake or the like and hits the open/close shutter, causing damage to the storage container when the open/close shutter is opened. Advantageously, the drug storage device of the present invention can also avoid such undesirable situations.
