Description

The present invention relates to a medicine dispensing device for supporting a dispensing operation in a hospital pharmacy or the like, and more specifically, a medicine dispensing device that stores various medicines in advance in a number of cassettes and automatically dispenses them as necessary. Relates to the device.
The chemicals handled by the chemical dispensing device are so-called round pharmaceuticals such as injections placed in a cylindrical container such as an ampoule. An infusion bottle or the like is applicable if it is in a cylindrical container.

2. Description of the Related Art There has been developed a medicine dispensing device in which medicines are stored side by side in a cassette, discharged one by one by a discharge mechanism, and transferred by a transfer mechanism (see, for example, Patent Documents 1 and 2).
The conventional apparatus includes a large number of cassettes that store and store chemicals in cylindrical containers such as ampules side by side, a support mechanism that holds these cassettes in a detachable or detachable manner, and the chemicals stored in each cassette. A discharge mechanism for discharging each one and a transfer mechanism for receiving and transferring the discharged chemicals are provided. In addition, the transfer mechanism is configured to send the transferred chemicals to a transporter beside the support mechanism by a horizontal transfer mechanism such as a belt conveyor.

In such a chemical dispensing device, chemicals that have moved due to natural fall or rolling fall on an inclined surface are transferred to both the transfer destination from the cassette and the transfer mechanism to the transporter. It came to stop by lightly colliding with the bottom and side walls. For this reason, although a slight impact is applied at the time of transfer, most chemicals are not broken even if they are contained in an ampule. Therefore, the transfer mechanism is embodied by a relatively simple belt conveyor with a side wall or a square box.
However, in the case of ampoules whose neck is pre-cut with chemicals, the head and the torso are separated even when pressed lightly with a fingertip, so the impact must be kept small. In particular, the impact on the end must be kept sufficiently small.

  Therefore, a chemical dispensing device has been developed that can gently transfer round chemicals (see, for example, Patent Document 3). In this conventional apparatus, in a medicine dispensing apparatus in which medicines in cylindrical containers such as ampoules are stored side by side in a cassette, discharged one by one by a discharge mechanism and transferred by a transfer mechanism The container body part and the container lid part form a split cylindrical curved part around the horizontal rotation center line and a projecting part that can be opened and closed and tapered when tapered, and the projecting part is directed obliquely upward Open and receive the discharged chemicals from the cassette in a horizontal position, and then lower the transferred parts downward or obliquely downward, and then open the transferred chemicals down and hand them over. A transfer container is provided in the transfer mechanism.

As described above, in the conventional medicine dispensing device, when the chemicals are put into the transporter by the transfer mechanism, the relatively difficult chemicals are not concerned whether they are separated one by one or plural. Dropping chemicals from the transport mechanism above the transporter into the upper opening of the transporter and storing the chemicals in the interior space of the transporter efficiently executes the charging operation, while for fragile chemicals, one by one The feeding operation is performed gently by moving the tip of the transfer container into the interior space of the transporter and then slowly lowering it to the inner bottom of the transporter.
And in any type of medicine dispensing device, the transporter is shallow, not too deep, or the quantity of chemicals entered is such that the chemicals are scattered and do not overlap in multiple stages. In use, it has been well received and put to practical use.

Further, as the experience of using such a medicine dispensing apparatus is accumulated and the benefits of automatic dispensing are recognized, the level of demand for automation has increased. Specifically, in order to improve the efficiency of transportation work and the like, there has been a demand for using a deeper carrying device than before, and for using the carrying device easily from empty to almost full without being limited by the input quantity.
However, when the container is deep, it is difficult to adopt the method of spontaneously dropping the chemicals from the upper opening of the transporter into the internal space when the chemicals are put into the transporter, because the chemicals are easily damaged. Moreover, it is desirable to avoid transferring chemicals one by one into the transporter as much as possible because the transfer efficiency is low even if the chemicals are fragile, and it is unavoidable to limit the control and operation.
Therefore, it is a basic technical problem to realize a medicine dispensing device that can accurately put round chemicals into a carrier regardless of whether the carrier is shallow or deep.

Furthermore, the method of placing the tip of the transfer container in the interior space of the transporter when the chemicals are loaded into the transporter has a large amount of chemicals to be charged, and multiple upstream operations can be performed on one transporter. If chemicals are pre-charged to the transporter in the dispensing machine, and the inner bottom of the transporter is raised by the charged chemicals, the charged chemicals may collide with the tip of the transfer container. If the impact is strong, chemicals are likely to be damaged.
Therefore, it is a further technical problem to realize a chemical dispensing device that can accurately input chemicals in a round shape regardless of whether the transporter is shallow, deep, or small in quantity, even if the amount already charged is small.

  The medicine dispensing device of the present invention (Solution means 1) has been devised in order to solve such a problem. The medicines in a cylindrical container such as an ampoule are aligned and stored in a cassette and are discharged by a discharge mechanism. In the medicine dispensing apparatus that discharges and then transfers the medicine by the transfer mechanism and puts it into the transporter, the transport mechanism moves back and forth between the position for receiving the medicines discharged from the cassette and the position for feeding the medicines to the transporter. A moving body, a transfer container that is mounted on the moving body in a longitudinal movement-permitting mode and whose upper surface is released and whose lower surface can be opened and closed; and a vertical movement and a lower surface of the transfer container that are mounted on the moving body An opening / closing drive mechanism for driving opening and closing, and a transmission mechanism for transmitting the drive of the opening / closing drive mechanism to the transfer container, and when receiving the discharged chemicals, the lower surface of the transfer container is closed to move the transfer container. When the chemicals are put into the container from the upper surface and the chemicals are put into the transporter from the transfer container, the transfer container is lowered so that the lower surface of the transfer container is put into the inner space of the transporter and then the lower surface of the transfer container is opened. It is characterized by becoming.

  Moreover, the medicine dispensing device of the present invention is (the solution means 2), the medicine dispensing device of the solution means 1, wherein the transmission mechanism includes a transmission portion by support and prevents the transfer container from being lowered. The drive transmission for lowering the transfer container is cut off.

  Furthermore, the medicine dispensing apparatus according to the present invention (Solution means 3) is the medicine dispensing apparatus of the above solution means 2, wherein the transmission mechanism lowers the bottom surface of the transfer container even when transmission of the drive for lowering the transfer container is interrupted. The drive to open the door is transmitted.

  Further, the medicine dispensing apparatus of the present invention (Solution means 4) is the medicine dispensing apparatus of the above solution means 3, and the equipment of the transfer container with respect to the moving body allows lateral movement in addition to vertical movement. The transfer container is configured to be movable at least partially in the lateral direction, and when the transfer container is moved laterally by the transmission mechanism, the lower surface is opened along with the lateral movement. It is characterized by that.

  Further, the medicine dispensing device of the present invention (Solution means 5) is the medicine dispensing apparatus of the above solution means 2 to 4, wherein the transmission part of the transmission mechanism is composed of a cam mechanism, It is equipped with the said mobile body, The cam follower of the said cam mechanism is equipped with the said transfer container, The said transfer container and its accessories are all passive members, It is characterized by the above-mentioned.

In such a medicine dispensing apparatus according to the present invention (Solution means 1), the transfer container that receives the chemicals discharged from the cassette and transfers them to the place of the carrying device accepts the release on the upper surface and performs the loading on the open / close lower surface. It is easy to simplify, and since it is further lowered from the lowered moving body and puts the lower surface into the interior space of the carrier, the lower surface is opened and thrown in, so of course when the carrier is shallow, Even when it is deep, the release start position is low and close to the inner bottom of the transporter, so there is no possibility that the chemicals will be broken by the impact at the time of dropping, even if there are one or more released chemicals.
Therefore, according to the present invention, it is possible to realize a medicine dispensing device capable of accurately feeding round chemicals into a transporter regardless of whether the transporter is shallow or deep.

Further, in the medicine dispensing apparatus of the present invention (Solution means 2), there are many medicines already charged or standing by chance, and the tip of the transfer container comes into contact with such an obstacle. When the lowering is prevented, the transmission of the drive for lowering the transfer container, that is, the transmission of the driving force and the movement is interrupted by the transmission mechanism, so that there is no possibility that the chemicals are broken by the impact of the collision. In addition, since such a transmission mechanism is embodied by a transmission portion that supports a base that is detachable up and down, undesired complication and enlargement of the transfer mechanism can be easily avoided.
Therefore, according to the present invention, it is possible to realize a medicine dispensing device capable of accurately feeding a round medicine into a carrier even if the carrier is shallow or deep, even if the amount already charged is small or large.

  Furthermore, in the medicine dispensing device of the present invention (Solution means 3), even when the transfer container is prevented from descending, the lower surface of the transfer container is opened, so that the introduction of the chemicals into the transporter can be completed.

  In the medicine dispensing apparatus according to the present invention (solution 4), as described above, the driving force or motion for moving the transfer container in the vertical direction is transmitted by the support, and the drive for opening and closing the lower surface of the transfer container is performed. In other words, by transmitting the driving force and movement by moving the transfer container in the lateral direction, the transmission of the different movements of vertical movement and opening and closing is the same two-dimensional movement of vertical movement and horizontal movement. Therefore, it is easy and simple to implement a transmission mechanism that transmits the driving force and motion to open the lower surface of the transfer container even when transmission of the driving force and motion to lower the transfer container is interrupted. Can do.

  Further, in the medicine dispensing apparatus of the present invention (Solution 5), the transfer container and its equipment are reduced in weight because the transfer container is not equipped with an active member such as an electric motor which is difficult to reduce in weight. The impact at the time of prevention will be weak.

This medicine dispensing device 10 (see FIG. 1 (a)) is equipped with a transport unit 15 at the bottom, an electrical unit 11 at the top, and two in the middle so as to be suitable for in-line connection with other automatic dispensing machines. The storage unit 13 is juxtaposed, and the transfer unit 12 is arranged in the middle between the left and right storage units 13.
The electrical unit 11 stores a power source and a controller (not shown), and the controller inputs prescription data and dispensing data from a console, a host computer, etc. (not shown) and generates operation commands to operate the units 12, 13, and 15. Is to control.
The transport unit 15 is provided with a transport mechanism 16 including, for example, a belt conveyor, in order to carry in the transporter 8 that stores the chemicals 6 to be dispensed and to transport the transporter 8 that stores the chemicals 6. 8 is conveyed in the horizontal direction.

  A large number of cassettes 14 are mounted in multiple stages (9 stages in the figure) in the storage unit 13 (support mechanism). The cassette 14 (see FIGS. 1 (a) to 1 (c)), which stores and arranges the chemicals 6 in a cylindrical container such as an ampule in a line in a horizontal state, should be suitable for sequential discharge. For example, it may be an existing one in which a movable lid for discharge is attached to the tip of a box body with an open top surface (see, for example, Patent Documents 1 and 2) or another structure. The storage unit 13 is configured to hold each cassette 14 in a horizontal state or an inclined state so that the cassette 14 can be pulled out or detached. For example, when the cassettes 14 are arranged in a single row at the front and rear (see FIG. 1B). The cassette 14 may be held by hand, and the hand may be extended and inserted into the storage unit 13 from the front or removed from the front. Further, when the cassettes 14 are arranged in a double row on the front and rear (see FIG. 1C), a drawer 17 may be provided for each stage of the storage unit 13, and the drawer 17 may be pulled out when the cassette 14 is attached or detached.

Each cassette 14 has a discharge port facing the transfer unit 12 when mounted in the storage unit 13, and a discharge mechanism 18 is provided at each position of the discharge port of the cassette 14 (see FIG. 1 (d)). Although only the guide plate is illustrated, the discharge mechanism 18 includes appropriate drive means and operating members such as an electric motor and a transmission mechanism (not shown) for opening and closing the discharge movable lid. The cassettes 14 and the transfer unit 12 are also provided in a suitable distributed manner so that the stored chemicals are discharged from the corresponding cassette 14 to the transfer unit 12 one by one in accordance with a discharge command from the controller.
The transfer unit 12 is provided with two transfer mechanisms 20 for receiving and transferring the chemicals 6 discharged from the cassette 14 for the left storage unit 13 and the right storage unit 13.

  The transfer mechanism 20 (see FIGS. 1 (d), 2 and 3) receives the chemicals 6 discharged from the cassette 14 by the discharge mechanism 18 and arrives at the transfer section 12, and transfers them downward, and then transports them. Therefore, a guide member 21 that extends vertically, a moving body 22 that moves up and down by being guided by the guide member 21 when driven by a motor (not shown), and a moving body 22 are provided. In addition, all (42 + 51) movements in the vertical direction relative to the moving body 22 are allowed, but a part (61) is allowed in the horizontal movement relative to the moving body 22. The transfer container 42 + 51 + 61 is also provided on the moving body 22 and is mounted on the moving body 22 in such a manner that the shaft rotates and does not move in the vertical and horizontal directions, and drives the vertical movement and the lower surface opening / closing of the transfer container 42 + 51 + 61. A motor closed drive mechanism 23 and not shown, which comprises a transmission mechanism 30 + 63 for transmitting the driving force and movement out of the opening and closing drive mechanism 23 to the transfer container 42 + 51 + 61.

  Moreover, the transfer mechanism 20 operates each motor according to the operation command of the controller. Specifically, the moving body 22 is moved up and down so that the moving body 22 and its equipment receive the chemicals 6 discharged from the cassette 14, and the position where the chemicals 6 are put into the transporter 8. To come and go. The moving body 22 is moved up and down between the cassettes 14 of each stage of the storage unit 13 and the transporter 8 of the transporting unit 15. When the arrangement state of the cassettes 14 and the transporting mechanism 16 is different, the moving body 22 moves horizontally or obliquely. Movement can also be combined. Furthermore, the transfer mechanism 20 is configured to move the transfer container 42 + 51 + 61 relative to the moving body 22 in the vertical and horizontal directions via the transmission mechanism 30 + 63 by the opening / closing drive mechanism 23 and the motor.

  Specifically, the transfer mechanism 20 (see FIG. 3A) is basically fixed to the moving body 22 in addition to the moving body 22 that is guided by the guide member 21 and moves up and down as described above. A longitudinal guide member 25, a swash plate 26, a swash plate 27, and a cam base 30 which is attached to the movable body 22 so as to be capable of rotating only in the same manner as the opening / closing drive mechanism 23. The vertical moving unit 40 that can move relative to the moving body 22 only in the vertical direction (vertical direction / vertical direction), and can swing relative to the vertical moving unit 40 (bidirectional rotation within a limited range). The oscillating unit 50 and a laterally moving unit 60 that can move relative to the longitudinally moving unit 40 only in the lateral direction (left-right direction and horizontal direction) are provided.

The opening / closing drive mechanism 23 may be a simple gear as shown in the figure, another reduction gear, a belt or the like as long as the rotation output of the motor can be transmitted to the cam base 30. In this example, the driving force from the rotation center 24 and the output of the rotational motion are performed at two locations, the front end portion and the rear end portion.
The longitudinal guide member 25 may be, for example, a fixed member portion of a slider mechanism in which the linear movement direction is vertical as long as the longitudinal movement unit 40 can be moved smoothly in the longitudinal direction. It is provided in two places with the end.

  The swash plates 26 and 27 are long plates extending from the front end portion to the rear end portion, and have a flat upper surface, and are inclined in a low state where they are high near the cassette 14 and the discharge mechanism 18 but low. The ends of the swash plates 26 and 27 near the discharge mechanism 18 are located immediately below a receiving port (not shown) formed near the discharge mechanism 18 on the side surface of the movable body 22 (FIG. 2B). reference). When the chemicals 6 discharged from the cassette 14 by the discharge mechanism 18 roll into the moving body 22 from the inlet of the moving body 22 and are placed on the inclined upper surfaces of the swash plates 26 and 27, the chemicals 6 The chemicals 6 are guided to the transfer container 42 + 51 + 61 on the inclined upper surface by rolling with their own weight, and may be combined into one sheet or divided into three or more sheets.

  The cam base 30 (see FIGS. 2 and 3A) is arranged directly on the moving body 22 or with the opening / closing drive mechanism 23 interposed between the rotation center 31 and the rotation center 24 of the opening / closing drive mechanism 23. The roller 32 is reciprocated on an arcuate locus by bi-directionally rotating within a limited range in accordance with the driving force and shaft rotation motion of the opening / closing drive mechanism 23. The roller 32 may be a simple sliding rod body or a rolling wheel with a bearing, as long as it can reciprocate while moving the cam follower 63 with low friction in contact with a cam contour curve 65 described later. In this example, the cam base 30 is also provided at two locations, the front end portion and the rear end portion.

The vertical movement part 40 (refer FIG. 2, FIG. 3 (a)) is provided with the movable member of the other side of the vertical direction guide member 25, and the horizontal direction guide member 41 and the end plate 42 which were fixed to it. In this example, the vertical movement part 40 is also provided in two places, the front end part and the rear end part.
The lateral guide member 41 may be, for example, a fixed member portion of a slider mechanism in which the linear movement direction is set to the lateral direction as long as the lateral movement unit 60 can be smoothly moved in the lateral direction.
The end plate 42 may have other shapes as long as the transport container 42 + 51 + 61 can be closed at both front and back ends so that the transporter 8 does not fall off. In this example, the end plate 42 is formed with a swing center 43 consisting of a simple or pivoted hole that supports the swing portion 50.

  The oscillating portion 50 (see FIGS. 2 and 3A) includes an oscillating plate 51 formed of a long plate from the front end portion to the rear end portion, and one on the front end portion and the rear end portion of the oscillating plate 51. Each swing arm 52 is fixedly mounted, and is mounted on the vertical movement unit 40 in a state where the swing center 53 coincides with the swing center 43 of the vertical movement unit 40. When the two-way rotation is performed, the rocking plate 51 is also rotated in the two-way direction. Further, since the swinging arm 50 is engaged with the swinging arm 52 so as to lean against a later-described roller 62 of the lateral movement unit 60, when the lateral movement unit 60 moves laterally with respect to the vertical movement unit 40, The swing arm 52 swings, and the swing plate 51 swings at the same time, so that the swing plate 51 changes the inclination. Furthermore, since the rocking | swiveling part 50 is connected with the moving body 22 via the vertical moving part 40, with respect to the moving body 22, a vertical direction movement and rocking | fluctuation can be performed.

  The lateral movement unit 60 (see FIGS. 2 and 3A) includes a movable member opposite to the lateral direction guide member 41, a lateral movement plate 61 composed of a long plate extending from the front end to the rear end, In this way, the roller 62 that receives the swinging arm 52 leaning obliquely from above and enables smooth relative movement at the time of lateral movement, and the cam follower 63 that forms a cam mechanism in combination with the above-described cam base 30. Since it is connected to the moving body 22 via the vertical moving unit 40, the moving body 22 can be moved both in the vertical direction and in the horizontal direction. In this example, the lateral movement plate 61 is single, but the movable member, the roller 62 and the cam follower 63 are provided at two locations, the front end portion and the rear end portion. The roller 62 is fixedly attached to the cam follower 63 so as to be suspended at the front end portion and the rear end portion. The roller 62 is moved along with the cam follower 63 together with the cam follower 63. 22 is moved relative to the vertical direction and the horizontal direction.

  Of these members, the upper end plate 42 for receiving the chemicals 6 is received by the two vertical end plates 42 in the front and rear, the inclined left swing plate 51 and the right lateral movement plate 61. An open transfer container 42 + 51 + 61 is configured (see FIGS. 2 and 3B). Further, the swash plates 26 and 27, the swinging plate 51, and the laterally moving plate 61 are chemical receiving and holding members 27 + 26 + 51 + 61. The transfer container 42 + 51 + 61 is located immediately below the swash plate 26 when the chemicals 6 are received. However, as the vertical movement unit 40 descends with respect to the moving body 22 (see FIG. 3B, the solid line with an arrow). (See FIG. 3 (c)), and by the rightward movement of the lateral movement portion 60, particularly the lateral movement plate 61 relative to the moving body 22, and the clockwise oscillation of the oscillation plate 51 associated therewith (FIG. 3 ( c) (see solid line with arrows), the lower surface is opened (see FIG. 3 (d)).

  In addition, the transfer container 42 + 51 + 61 is moved by the leftward movement of the laterally moving portion 60, particularly the laterally moving plate 61 with respect to the moving body 22, and the counterclockwise swinging of the swinging plate 51 (FIG. 3D). The lower surface is closed (see FIG. 3C), and as the vertical movement unit 40 rises with respect to the moving body 22 (see the broken line with arrows in FIG. 3C), it rises to the swash plate 26. (See FIG. 3B). Such a transfer container 42 + 51 + 61 is always open at the upper surface, and when it is moved in the lateral direction by the transmission mechanism 30 + 63, the lateral movement of the lateral movement plate 61 and the oscillation of the oscillation plate 51 associated therewith. The lower surface opens and closes by separating the lower end portion.

  Such transfer containers 42 + 51 + 61 and their equipment 40 + 50 + 60 are all made of passive members, and their operations are defined by the cam of the transmission mechanism 30 + 63 that transmits the driving force and the rotational movement of the opening / closing drive mechanism 23. The transmission mechanism 30 + 63 is a combination of a cam base 30 and a cam follower 63 that form a cam mechanism, and the cam base 30 is mounted on the moving body 22, and the cam follower 63 is a laterally moving portion. 60 is connected to the lateral movement plate 61 and is mounted on the transfer container 42 + 51 + 61 via the lateral movement plate 61.

  The cam follower 63 of the transmission mechanism 30 + 63 has a large cam clearance 64 formed by punching or punching, and the cam contour curve 65 in which the upper side, the left side, and the upper side of the right side come into contact with the roller 32 of the cam base 30. The movement of the roller 32 and the shape of the cam contour curve 65 define the trajectory of the cam follower 63 and the movements of the vertical movement unit 40, the swinging unit 50, and the horizontal movement unit 60. The roller 32 of the cam original section 30 swings downward between the upper left and the right as viewed from the rotation center 31 according to the control of the controller (the solid line and the arrow in FIG. 3A). (See dotted line).

  In addition, in this transmission mechanism 30 + 63, as described above, a cam escape place 64 larger than the roller 32 of the cam main link 30 is vacated below the cam contour curve 65 of the cam follower 63. Since the roller 32 of the cam base 30 is in contact with the cam contour curve 65 on the upper side of the escape place 64 so as to be received from below, the cam base 30 supports the cam follower 63 so as to be detachable in the vertical direction. It has become. In addition, the transmission mechanism 30 + 63 including the transmission unit 32 + 65, which is a transmission unit by such a bearing, interrupts the transmission of the driving force and the movement to lower the transfer container 42 + 51 + 61 when the lowering of the transfer container 42 + 51 + 61 is prevented. Yes.

  Further, in the cam follower 63, there are members that come into contact with the roller 32 of the cam original node 30 so as to be freely separated from the side on the left and right of the cam escape area 64. Therefore, the transmission mechanism 30 + 63 has the roller 32 of the cam original node 30. Even when the cam follower 63 is separated from the cam contour curve 65 and the transfer of the driving force and the motion for lowering the transfer container 42 + 51 + 61 is interrupted, the roller 32 pushes the left side portion or the right side portion of the cam follower 63, The follower 63 is moved laterally, and the lateral moving plate 61 is moved laterally, and the driving force and motion for opening the lower surface of the transfer container 42 + 51 + 61 are transmitted.

  And (refer to the solid line with an arrow in FIG. 3A), when the roller 32 of the cam original node 30 swings from the upper left to the lower side of the rotation center 31, the longitudinal movement unit 40, the oscillation unit 50, and the lateral movement unit 60 When the roller 32 is further lowered and the roller 32 swings from the bottom to the right of the rotation center 31, the lateral movement unit 60 moves in the right direction and the swinging unit 50 swings clockwise to open the lower surface of the transfer container 42 + 51 + 61. The moving unit 40, the swinging unit 50, and the lateral moving unit 60 are slightly raised. Conversely (see the broken line with an arrow in FIG. 3A), when the roller 32 of the cam base 30 swings from the right to the bottom of the rotation center 31, the vertical movement unit 40, the rocking unit 50, and the horizontal movement unit 60 are moved. When the roller 32 is slightly lowered and the roller 32 swings from below the rotation center 31 to the upper left, the lateral movement unit 60 moves leftward and the swinging unit 50 swings counterclockwise, so that the lower surface of the transfer container 42 + 51 + 61 Further, the vertical movement unit 40, the swinging unit 50, and the horizontal movement unit 60 are raised.

  Further, the control of the roller 32 of the cam base 30 by the controller is performed so as to be suitable for the receiving operation of the chemicals 6 and the charging operation to the transporter 8, so when the transfer mechanism 20 receives the discharged chemicals 6, the chemicals The moving body 22 is moved up and down to the cassette 14 and the discharge mechanism 18 that are about to discharge 6 and the lower surface of the transfer container 42 + 51 + 61 is closed, and the chemicals 6 are put into the transfer container from the upper surface. When the moving body 22 is lowered from 42 + 51 + 61 to the transporter 8, the transfer container 42 + 51 + 61 is further lowered, so that the lower surface of the transfer container 42 + 51 + 61 and the lower end of the container are placed in the inner space of the transporter 8, and then the lower surface of the transfer container 42 + 51 + 61 is It can be opened.

  About the chemical | drug | medicine delivery apparatus 10 of this Example 1, the use aspect and operation | movement are demonstrated referring drawings. 4 to 10 are a front view of a main part of the medicine dispensing apparatus 10 and a cross-sectional view of the medicine receiving and holding member 27 + 26 + 51 + 61. 4 shows that the transfer mechanism 20 has received the chemicals 6 from the cassette 14, and FIG. 5 shows that the transfer mechanism 20 has received the chemicals 6 from the cassette 14.

  6 shows that the transfer mechanism 20 has been lowered directly above the transporter 8, FIG. 7 shows that the transfer container 42 + 51 + 61 has been put into the transporter 8, and FIG. The bottom surface of 42 + 51 + 61 is opened and the chemicals 6 are released into the transporter 8. Further, FIG. 9 shows the state where the lowering of the transfer container 42 + 51 + 61 is prevented when the transfer container 42 + 51 + 61 is put in the transporter 8, and FIG. 10 shows the transfer after the lowering of the transfer container 42 + 51 + 61 is prevented. The bottom surface of the container 42 + 51 + 61 is opened, and the chemicals 6 are released into the transporter 8.

  Prior to automatic dispensing, various chemicals 6 are stored in alignment in each cassette 14 (see Patent Documents 1 and 2). When a dispensing instruction is given, that is, when prescription data or dispensing data is input to the controller, the controller's control program is executed based on the prescription data or dispensing data, and the dispensing operation is automatically performed. Further, the transporter 8 is transferred to the transport mechanism 16 from an adjacent transporter supply device or dispenser (not shown), and the transporter 8 is placed directly below the transfer unit 12 by the transport mechanism 16. Then, the medicines 6 to be dispensed are discharged from the corresponding cassette 14 by the discharge mechanism 18, and the chemicals 6 are transferred to the transporter 8 by the transfer mechanism 20. When the necessary chemicals 6 are collected in the transporter 8 by repeating this process, the transporter 8 is sent out by the transport mechanism 16 to an adjacent transporter storage device or dispenser (not shown).

Hereinafter, in the above operation, the transfer mechanism 20 is moved up and down to the discharge mechanism 18 of the cassette 14 to discharge the chemicals 6, and then the discharged chemicals 6 are received by the transfer mechanism 20 and then the transporter 8. Will be described in detail (see FIGS. 4 to 10).
First (see FIG. 4), when the moving body 22 arrives at a position to receive the discharged chemicals 6 from the cassette 14 to be discharged, the transfer mechanism 20 keeps the roller 32 at the upper left of the rotation center 31, so that the transfer container 42 + 51 + 61. Is positioned relative to the moving body 22 and closes the lower surface. Therefore, the discharged chemicals 6 released from the discharge mechanism 18 enter the transfer mechanism 20 from the receiving port of the moving body 22, and then roll on the upper surfaces of the swash plate 27 and the swash plate 26 to enter the transfer container 42 + 51 + 61. Roll in.

  When a specified number (three in the figure) of chemicals 6 is stored in the transfer container 42 + 51 + 61 (see FIG. 5), one or more, the transfer mechanism 20 is lowered and the moving body 22 is moved to the transporter 8. Stop when it is just above (see FIG. 6). Then, when the roller 32 of the cam original section 30 swings downward from the upper left of the rotation center 31 and comes under the rotation center 31 (see FIG. 7), the large moving body 22 is stopped and the transfer container 42 + 51 + 61 is stopped from there. Descends and most of the transfer container 42 + 51 + 61 including the lower surface enters the internal space of the transporter 8. The chemicals 6 accommodated and transferred in the transfer container 42 + 51 + 61 also enter the inner space of the transporter 8 together with the transfer container 42 + 51 + 61 and approach the inner bottom of the transporter 8.

Further, when the roller 32 of the cam base 30 continues to swing and passes below the rotation center 31 to the right (see FIG. 8), the lateral movement plate 61 moves to the right and swings accordingly. The plate 51 swings clockwise, and the transfer container 42 + 51 + 61 rises slightly while opening the lower surface. Then, the chemicals 6 are released from the transfer container 42 + 51 + 61 into the inner space of the transporter 8, but since the chemicals 6 are only dropped from a position close to the inner bottom of the transporter 8, there is no possibility of breaking due to the impact of the drop.
The transfer mechanism 20 that safely puts the chemicals 6 into the transporter 8 in this way operates in the reverse order as described above, and ascends to a position for receiving the discharged chemicals 6 from the next cassette 14 to be discharged.

  And (refer to FIG. 9), the transfer of the chemicals 6 is repeated, and the chemicals 6 accumulate in the carrying device 8, and when the height of the stack of the chemicals 6 increases, the transfer container 42 + 51 + 61 descends eventually. For example, the lower end of the laterally moving plate 61 hits the uppermost chemicals 6 when entering the transporter 8, but in that case, if the lowering of the transfer container 42 + 51 + 61 is prevented by the contact, The cam contour curve 65 moves away from the roller 32 in the support transmission portion 32 + 65 included in the transmission mechanism 30 + 63, and the drive or transfer that has been transmitted from the opening / closing drive mechanism 23 to the transfer container 42 + 51 + 61 through the transmission mechanism 30 + 63 until then. Since the driving force and movement to lower the container 42 + 51 + 61 are not transmitted, the transfer container 42 + 51 + 61 may give an undesired impact to the chemicals 6. Without medicines, 6 to stop the descent at that contact.

  Then (see FIG. 10), the transfer container 42 + 51 + 61 must open the lower surface in order to release the chemicals 6, but the lower surface of the transfer container 42 + 51 + 61 even when the transmission of the drive mechanism 30 + 63 lowering the transfer container 42 + 51 + 61 is cut off. Since the driving force for opening the opening is transmitted, the transfer container 42 + 51 + 61 also moves the lateral movement plate 61 to the right and swings the swinging plate 51 clockwise to open the lower surface. To rise. Then, the chemicals 6 are released from the transfer container 42 + 51 + 61 into the internal space of the transporter 8. However, since the chemicals 6 are gently dropped on the chemicals 6 immediately below, any chemicals 6 are dropped. There is no risk of breaking on impact.

[Others]
In addition, since the swinging of the swing plate 51 is not compulsory among the transfer containers 42 + 51 + 61, there is no possibility that the swinging plate 51 swings and damages the chemicals 6, but the right of the lateral movement plate 61 of the transfer containers 42 + 51 + 61 is not. Since the directional movement is forced, a cushioning material is used for the lower end or lower half of the laterally moving plate 61 in order to alleviate the impact at the time of contact or lateral movement. It is even better to make such modifications.
In the above embodiment, two storage units 13 and two transfer mechanisms 20 are provided. However, one or three or more storage units 13 may be provided. If the transfer mechanisms 20 can be shared, the storage unit 13 is provided. A smaller number is acceptable. Further, the transfer unit 12 may be arranged on the back side with the cassette 14 facing forward, and the cassette 14 may be detached from the side without the discharge mechanism 18.
