Abstract

PROBLEM TO BE SOLVED: To provide a simple medicine cassette capable of reducing impact on medicines remaining after delivering head-end medicines even if the cassette is vertical accommodating type.SOLUTION: The cassette has a structure in which notches 16a for allowing push-out members 23 to pass when the push-out members 23 are in rotation are formed on an inner bottom 16 of an alignment accommodating section, and each push-out member 23 employs a spiral member spirally protruding from a support shaft 22 in the outer circumferential direction and simply increasing its spiral radius from the outer circumferential surface 23d of the near-center portion close to the support shaft 22 to the outer circumferential surface 23b of the far-center portion close to a front end 23a. When the support shaft 22 is pivotally rotated, the front end 23a of the push-out member 23 pops up from the inner bottom 16 accordingly, and abuts to the lowermost one of the medicines 6 to laterally forward it, and the subsequent one of the medicines 6 on the inner bottom 16 is temporarily supported until the outer circumferential surfaces 23b-23d of the push-out members 23 come under the inner bottom 16.

Description

  The present invention relates to a chemical cassette that arranges and stores chemicals and sequentially discharges and sequentially discharges them. More specifically, the present invention relates to a chemical cassette that stacks and holds a large number of chemicals and discharges them laterally in order from the bottom.

  FIG. 5 shows some perspective views of the appearance of chemicals. Among them, PTP packaging agent 2 (see FIG. 5 (a)) is a product in which a plurality of medicines are packaged with a PTP sheet. A typical shape is a square plate in which one side is flat and the other side is lined with protrusions (pockets) for storing medicines. Its typical size is several tens of mm in width and hundreds of tens of mm in length, typical weight / mass is several tens to several hundreds of mg, and typical thickness is several mm. Further, a PTP binding body 4 is formed by stacking a plurality of such PTP packaging materials 2 and a large number, for example, about 10 sheets, and then winding and binding a binding band such as a transparent polypropylene film (FIG. 5B). )), And the PTP bundle 4 is a pillow package 6 that is secondarily wrapped with aluminum foil or PE film for oblique light or sealing (see FIG. 5 (c)). The boxed body 8 is formed by packing it into, for example, a paper box to form a rectangular parallelepiped (see FIG. 5D).

These chemicals 2 to 8 are difficult to roll, but for chemical cassettes that handle easy-to-roll ampule-filled injections, those that are lined up and discharged sequentially have been put into practical use. Specifically, it is a medicine dispensing device in which a large number of cassettes are incorporated (see, for example, Patent Document 1). A support mechanism for holding the cassette in a detachable or detachable manner, an urging mechanism for urging the stored chemicals in the cassette toward the chemical discharge port, and a counting means for determining the number of stored chemicals in the cassette; , Taking out the stored chemicals from the chemical discharge port of the cassette and transporting the stored chemicals to a predetermined position, and rotating the shaft by the payout transport mechanism to remove the stored chemicals from the chemical discharge port of the cassette. A movable lid capable of rotating the shaft to be discharged and a reading device for reading chemical information attached to the container of the chemicals to be discharged are provided.
In this device, the chemicals are arranged in a horizontal row, and the movable lid prevents the next chemicals from moving forward in the first half of the shaft rotation, allowing the top chemicals to be discharged. Subsequent chemicals are ready to move forward.

In addition, chemical cassettes that handle chemicals such as flat infusion bottles that are not so easy to roll have been put into practical use in which chemicals are arranged and stored on a gently inclined sliding surface and sequentially discharged. In this chemical cassette (see, for example, Patent Document 2), a sliding surface is formed by arranging rollers in an inclined direction, and a discharge member that connects a flat plate portion and a curved plate portion is dropped on the sliding surface. The flat plate portion is provided in the vicinity of the end, and is supported so as to be able to swing in a state where the swing center is placed on the extension of the sliding surface, and the curved plate portion maintains a constant distance from the swing center. The flat plate portion extends from the end near the sliding surface to the lower side of the flat plate portion, and a drive source for swinging the discharge member is provided below the sliding surface on the lower side. Is.
Even in this chemical cassette, the chemicals are arranged in a row on the sliding surface, and the discharge member is capable of discharging the first chemical while preventing the advance of the next chemical in the first half of the swinging movement. Immediately after the end of swinging, the next and subsequent chemicals are ready to move forward. Since this chemical cassette is a sliding type, it is possible to handle the boxed body 8 that is difficult to roll.

Furthermore, there is a chemical cassette in which a large number of chemicals are stacked and held in a vertical direction and are laterally fed in order from the bottom to be discharged (for example, see Patent Documents 3 and 4).
Among them, the chemical cassettes suitable for handling the above-mentioned PTP packaging material 2 (see, for example, Patent Document 3) are aligned storage that holds the PTP packaging material 2 in a state of being stacked and aligned and stored vertically. And a sequential discharge mechanism for horizontally feeding the PTP packaging agent 2 in the longitudinal direction from the bottom to the front and discharging it forward. The alignment storage portion is formed of a box body having a discharge port formed in the lower end portion, and includes an inner bottom member that holds the PTP packaging material 2 on the upper surface. The sequential discharge mechanism includes a hook member that hooks the rear end of the lowermost PTP packaging material 2 and a feed mechanism that forwards the hook member along the inner bottom member.

On the other hand, a chemical cassette suitable for handling the PTP bundle 4 described above (see, for example, Patent Document 4), instead of a hook member, an extrusion member that pushes the rear end of the lowermost PTP bundle 4 is used. It has.
In any case (refer to Patent Documents 3 and 4), in the conventional chemical cassette in which the chemicals stacked up and down are laterally fed in order from the bottom, when the lowest chemical is discharged, the gap formed there However, the second and subsequent chemicals will drop at once, just like a brushed-down.

JP 2005-125013 A JP 2006-288573 A JP 2009-131560 A JP 2009-165675 A

In such a conventional chemical cassette, in the case of a so-called horizontal storage type (see Patent Documents 1 and 2) in which a large number of chemicals are held back and forth, when they are arranged in multiple stages and incorporated in a chemical dispensing device There is an advantage that the storage capacity is large, but it is not easy to visually check the stored chemicals.
On the other hand, in the case of the so-called vertical storage type in which a large number of chemicals are stacked up and down (see Patent Documents 3 and 4), even if they are arranged in multiple stages and incorporated in a chemical dispensing device, the front of the cassette is made transparent. It is possible to easily visually check the stored chemicals by forming a vertically long window or the like on the front surface of the cassette. In addition, there is an advantage that the alignment storage section is simple and the discharge speed is easy to increase. However, since they are stacked, they are not good at heavy chemicals or brittle chemicals.

For this reason, horizontal storage chemical cassettes are often used for handling chemicals in ampoules and bottles, etc., but generally light and hard to break PTP wrapping agent 2 and PTP bundle 4 and their packaging. For handling the body 8 or the like, a horizontally stored chemical cassette is also used, but the use of a vertically stored chemical cassette is increasing. This tendency is the same for the pillow packaging body 6 that can be said to be an intermediate between the PTP binding body 4 and the boxed body 8.
However, in the case of the pillow packaging body 6, the packaging bag is thin, even though it is not heavy and not fragile. Therefore, even if the function of the medicine inside is maintained, the appearance is impaired.

In many cases, the PTP packaging agent 2 is supplied in a boxed body 8 and is easier to handle than the pillow package 6 in the state of the boxed body 8 or the PTP bound body 4, so the PTP bound body 4 or the boxed body 8. However, there are cases where it is necessary to pay out in the state of the pillow package 6 instead of the PTP bundle 4 or the box 8. In this case, a large number of pillow packaging bodies 6 are arranged and stored in a chemical cassette and sequentially discharged. However, after the first pillow packaging body 6 is discharged, the second and subsequent pillow packaging bodies 6 are gathered at once. If it stops suddenly in front of the discharge port after proceeding, an impact is applied to the second pillow package 6. The impact is likely to be large in the vertical storage type, but it is desirable that the impact is small not only in the pillow package 6 but also in other chemicals.
Therefore, it is a technical problem to easily realize a chemical cassette that requires only a small impact to the chemicals remaining after the top chemicals are discharged even in the vertical storage type.

The chemical cassette of the present invention (Solution 1) was created to solve such a problem,
An alignment storage unit that holds a large number of chemicals in a storage space in which a discharge port is formed on the edge of the inner bottom portion, and is stacked vertically and stored in an aligned manner, and among the chemicals In the chemical cassette with a sequential discharge mechanism that discharges the chemicals in order from the bottom by pushing the bottom one from the side with an extrusion member and sending it out from the discharge port,
A lateral support shaft that is separate or integral with the push member and supports the push member, and a driving means for rotating the support shaft are provided in the sequential discharge mechanism,
A notch through which the pusher member passes during rotation of the pusher member is formed in the inner bottom of the alignment storage unit;
A spiral member that protrudes spirally from the support shaft in the outer peripheral direction and monotonously increases the outer peripheral surface radius from the mesial portion outer peripheral surface near the support shaft to the centrifugal portion outer peripheral surface near the tip portion is adopted as the extrusion member. Has been
When the support shaft is rotated, along with this, the tip of the extruding member comes out on the inner bottom portion and abuts against the lowest one of the chemicals and is laterally fed. Of these, what comes next on the inner bottom is supported for a while until the outer peripheral surface of the pushing member is below the inner bottom.

  Further, the chemical cassette of the present invention (Solution means 2) is the chemical cassette of the above-mentioned solution means 1 and does not oscillate with the pressure of only the chemicals but oscillates with the pushing force of the pushing member. An optical discharge sensor for detecting the discharge of chemicals from the discharge port directly in a non-contact manner, wherein the anchoring device is mounted on the alignment storage unit with the swinging end positioned outside the discharge port. In addition, a swing sensor that indirectly detects the discharge of chemicals from the discharge port by operating according to the swing of the swing fastener is provided.

  Further, the chemical cassette according to the present invention is (Solution means 3), which is the chemical cassette of the above-mentioned solution means 2, wherein the discharge sensor and the swing sensor are both used for the chemical discharge operation by the sequential discharge mechanism. When it is sensed, it is determined as a normal state, but when only one of them is sensed, it is determined as an abnormal state and the subsequent discharging operation is stopped.

In such a chemical cassette of the present invention (Solution 1), when the lowest chemical is sent out by the tip of the extruding member and becomes empty, the second chemical falls there. The second chemicals are supported by the outer peripheral surface of the extruded member for a while.
Since the outer peripheral surface of the extruded member monotonously increases the outer peripheral surface radius from the outer peripheral surface of the mesial part to the outer peripheral surface of the centrifugal part, the part that supports the second chemical for a while is not so from the outer peripheral surface of the centrifugal part near the tip part. Since it moves to the outer peripheral surface of the mesial portion, the second chemicals do not fall freely, but fall slowly with the dropping speed regulated by the outer peripheral surface of the pushing member.

Therefore, the drop impact on the second chemical and the chemicals stacked on the second chemical is alleviated and eliminated.
Moreover, not only the lowest chemical feed function but also the second chemical fall speed regulating function is realized by a spiral extruded member that rotates and moves in and out on the inner bottom.
Therefore, according to the present invention, it is possible to simply realize a chemical cassette that requires only a small impact on the chemicals remaining after the top chemicals are discharged even in the vertical storage type.

  Further, in the chemical cassette of the present invention (solution means 2 and 3), not only the chemical discharge from the discharge port is detected in a non-contact and direct manner by an optical discharge sensor, but also the swinging fastener Indirect detection with a swing sensor that operates in response to the swing of the actuator enables double check, which not only improves reliability by making multiple but also is intuitive because it is direct detection Completion of the extraneous sensor, which is a discharge sensor that can be relied on, and indirect detection but is a rocking sensor that is resistant to dust and dirt, etc., is expected to improve the reliability beyond the effect of multiple use.

About Example 1 of this invention, the structure of a chemical | medical agent cassette is shown, (a) is an external appearance front view, (b) is a vertical front view, (c) is a vertical right side view, (d) and (e) are PTP. It is a vertical side view of a single unit and a side-by-side group incorporated in the dispensing device. The front half part of the operation | movement at the time of chemical | medical agent discharge | emission is shown, (a)-(d) all are vertical right side views. The latter half part of operation | movement at the time of chemical | medical agent discharge | emission is shown, (a)-(d) all are vertical right side views. About Example 2 of this invention, the structural example of an extrusion member is shown, (a)-(d) is a perspective view, (e)-(f) is a side view. It is an external perspective view of chemicals, (a) is a PTP packaging agent, (b) is a PTP bundle, (c) is a pillow package, and (d) is a box.

About the chemical | medical agent cassette of such this invention, the specific form for implementing this is demonstrated by the following Examples 1-2.
The embodiment 1 shown in FIGS. 1 to 3 embodies the above-described solving means 1 to 3 (claims 1 to 3 as originally filed), and the embodiment 2 shown in FIG. It is a modification.
In the illustration, for the sake of simplicity, fasteners such as bolts, coupling tools such as hinges, electric circuits such as motor drivers, electronic circuits such as controllers, etc. are omitted from the illustration. The illustrations focus on what is needed and what is relevant.

About the Example 1 of the chemical | medical agent cassette of this invention, the specific structure is demonstrated with reference to drawing. 1A to 1C show a chemical cassette 10 in which a single unit is placed upright, (a) is an external front view, (b) is a vertical front view, and (c) is a vertical right side. FIG.
FIG. 4D is a vertical side view of a single chemical cassette 10 installed slightly tilted rearward, and FIG. 4E shows that the chemical cassettes 10 installed in an inclined manner are installed in multiple stages facing each other. 3 is a longitudinal side view of the main part of the PTP payout device 30. FIG.

The chemical cassette 10 includes an alignment storage unit 11 to 16 that holds the pillow package 6 (chemicals) described above horizontally, stacked vertically and stored in an aligned manner, and the pillow package. 6 are provided with sequential discharge mechanisms 21 to 26 for horizontally feeding 6 from the bottom and discharging them to the rear.
The alignment storage portions 11 to 16 are vertically long box-like bodies made of, for example, metal or hard plastic, and include a left side plate 11, a back plate 12, a right side plate 13, and a front plate 14 that surround the storage space 10 a of the pillow package 6. Although it has an inner bottom portion 16, the upper surface is opened for easy refilling, etc., the front plate 14 is of an openable type, and when the front plate 14 is closed, the closed state of the front plate 14 is maintained by a magnetic force or the like. It has come to be. Although not shown in the figure on the front surface of the front plate 14, for example, a label printed with a medicine name and identification code in the pillow package 6 is provided so that the medicine confirmation at the time of replenishment and the barcode input operation can be performed easily and accurately. It is pasted.

Further, the alignment storage portions 11 to 16 are arranged so that the pillow package 6 can be easily visually confirmed from the front, regardless of the number of pillow packages 6 stored in the storage space 10a. The width of 14 is narrower than the width of the storage space 10a, so that the storage space 10a can be looked into from the front of the cassette.
Furthermore, in this alignment storage part 11-16, the lower end part of the backplate 12 is notched to the edge of the inner bottom part 16, and the discharge port 10b is formed there. The discharge port 10b is formed in such a size that the lowest one of the pillow packages 6 can pass smoothly, but the second one from the bottom of the pillow packages 6 and the one above it cannot be passed. ing.

  Moreover, in this alignment storage part 11-16, the rocking | fitting clasp 15 which makes an upper end part a rocking | fluctuation center is mounted | worn with the outer surface of the backplate 12, and the lower end part hangs down to the discharge port 10b. Moreover, since the swinging fastener 15 is constantly urged toward the back plate 12 by the spring elastic force, magnetic force, etc., the lowermost pillow wrapping body 6 can be removed from the discharge port 10b by some time. Even if it begins to move out of the way, if the swing retainer 15 cannot be swung by overcoming the biasing force, the lower end of the swing retainer 15 is prevented from moving, and the storage space 10a. It remains on the upper surface of the inner bottom portion 16. Further, a swing sensor 15a composed of, for example, a contact mechanical switch is mounted on the outer surface of the back plate 12 near the lower end of the swing retainer 15, and the swing sensor 15a is mounted on the swing retainer 15a. When the tool 15 approaches the back plate 12 within the swing range, it is pushed and turned on by the swing fastener 15, and when the tool 15 moves away from the back plate 12 within the swing range, the tool 15 is separated from the swing plate 15. Therefore, the discharge of the chemicals from the discharge port 10b is indirectly detected by operating according to the swing of the swing fastener 15.

The sequential discharge mechanisms 21 to 26 include a lower frame 21, a support shaft 22, an extrusion member 23, an electric motor 24, a transmission gear 25, and a discharge sensor 26, and are provided below the alignment storage units 11 to 16. The top plate portion of the lower frame 21 also serves as the inner bottom portion 16 of the storage space 10a.
The lower frame 21 is formed by assembling a plate body made of, for example, metal or hard plastic into a short box shape, and the top frame portion also serving as the inner bottom portion 16 of the lower frame 21 and the front plate portion connected thereto are extruded. The same number of notches 16 a that allow the push-out member 23 to pass through during the rotational movement of the member 23 are formed as many as the push-out member 23. With respect to the lower frame 21, the support shaft 22, the pushing member 23, the electric motor 24, and the transmission gear 25 are incorporated, and the discharge sensor 26 is externally provided. The discharge sensor 26 may be the same optical discharge sensor as that provided in a conventional cassette (see Patent Documents 1 to 4), and may be a reflected light detection type or a light shielding detection type, and discharges chemicals from the discharge port 10b. Is detected directly without contact.

The support shaft 22 is formed of, for example, a metal shaft having a round bar shape, and both ends thereof are supported by side plates of the lower frame 21 and are horizontally oriented with the axial direction / longitudinal direction being horizontal or a direction close thereto.
The electric motor 24 and the transmission gear 25 are driving means for rotating the support shaft 22, and the rotation output shaft and the support shaft 22 are meshed with the transmission gear 25 interposed therebetween. Then, according to the control of a built-in or external control circuit (not shown), the spindle 22 is rotated every time one pillow package 6 needs to be discharged, and when the discharge is completed, the spindle 22 is rotated. It is supposed to stop.

  Whether or not the pillow package 6 is discharged is directly detected by the optical discharge sensor 26, for example, but is also detected indirectly by the swing detection of the swing fastener 15 by the swing sensor 15a. Preferably, the control circuit double-checks based on the swing sensor 15a and the discharge sensor each time the control circuit sequentially causes the discharge mechanisms 21 to 26 to discharge one pillow package 6. 26, the control circuit determines that the chemical discharge operation is normal when the discharge operation of the pillow package 6 is detected in response to both of them, and permits the next chemical discharge operation. When only one of the sensors 26 is sensitive, the control circuit determines that some abnormality has occurred and stops the subsequent discharging operation. When neither the swing sensor 15a nor the discharge sensor 26 is sensitive, a control circuit is provided to determine that the cassette is empty.

  In this example, about two extruding members 23 are provided, both of which are externally fitted to the support shaft 22 and fixed to the support shaft 22 at an appropriate distance. With the support of the support shaft 22, when the support shaft 22 rotates, the pusher member 23 rotates accordingly. In addition, the pushing member 23 as seen from the axial direction of the support shaft 22 as viewed from the end surface / side surface of the pushing member 23 has a shape protruding in a spiral shape from the support shaft 22 to the outer circumferential direction, and the tip portion 23a moves circularly during rotation. It is something to be made. Further, the outer peripheral surface of the pushing member 23 monotonously increases the outer peripheral surface radius and the vortex radius from the mesial outer peripheral surface 23d near the support shaft 22 through the intermediate outer peripheral surface 23c to the centrifugal outer peripheral surface 23b near the tip 23a. It is shaped and finished with a smooth surface.

  When the support shaft 22 is rotated by the electric motor 24, the pusher member 23 rotates and the tip 23a moves circularly (see the two-dot chain line in FIG. 1C). As a result, the front end portion 23a of the push-out member 23 protrudes from the bottom of the inner bottom portion 16 onto the inner bottom portion 16 and comes into contact with the lowermost one of the pillow packaging bodies 6 so that the lowermost pillow packaging body 6 is laterally fed. It is supposed to be. In addition, the bottom pillow package 6 is fed out of the cassette from the discharge port 10b by the lateral feed, and in addition, the second one of the pillow packages 6 that comes next on the inner bottom portion 16 is extruded. The member 23 is supported for a while until the outer peripheral surface of the member 23 is below the inner bottom portion 16. In addition, at that time, the outer peripheral surface portion to be supported is changed in the order of the centrifugal portion outer peripheral surface 23b, the intermediate portion outer peripheral surface 23c, and the mesial portion outer peripheral surface 23d.

Such a chemicals cassette 10 may be installed upright (see FIGS. 1 (a) to 1 (c)), but may be installed with an inclination of 5 ° to 10 °, for example (FIG. 1). (See (d)), the visibility and replenishment workability are often improved.
The chemical cassette 10 may be provided with a dedicated control circuit to operate the single chemical cassette 10 independently. However, when a large number of chemical cassettes 10 are incorporated in the chemical dispensing device 30 (see FIG. 1 (e)), a pair of chemical cassettes 10 with the rear side facing each other are arranged side by side (through the paper surface), and a transport mechanism 31 for collecting the pillow package 6 after discharge is installed below it. It is preferable to form one stage and arrange it in the vertical direction to make it multistage.

  About the chemical | medical agent cassette 10 of this Example 1, the usage mode and operation | movement are demonstrated referring drawings. 2 and 3, (a) to (d) are vertical right side views of the chemical cassette 10, and show the operation of discharging the pillow package 6 in time series. Here, when it is desired to distinguish the individual pillow packages 6, reference numerals such as 6a and 6b are used.

  When the chemical cassette 10 is empty, the front plate 14 is manually opened and the pillow package 6 is replenished from the front of the release. At that time, after laying each pillow package 6 sideways, align the longitudinal direction and the short direction of a large number of pillow packages 6 in the same direction as much as possible and stack them on the upper surface of the inner bottom portion 16 to align them. The pillow package 6 is stored in the storage space 10a of the storage units 11-16. Then, the side of the stored pillow wrapping body 6 is pushed with a finger or the like and lightly pressed against the back plate 12 to arrange the rows of pillow wrapping bodies 6. In this way, a large number of pillow packages 6 are aligned and stored in the vertically long storage space 10a, so that when the front plate 14 is closed, the pillow packages 6 are ready for sequential discharge (see FIG. 2A).

  Thereafter, when the pillow packaging bodies 6 are discharged one by one, a discharge instruction or instruction is given to a control circuit (not shown), and the chemical cassette 10 is discharged. Specifically, the control circuit operates the electric motor 24 while confirming that the reflected light is not detected by the discharge sensor 26. As a result, the support shaft 22 rotates, and the pusher member 23 rotates accordingly, and the front end portion 23a of the pusher member 23 turned upward or upward passes through the notch 16a and passes through the inner bottom portion. Proceed backwards after exiting above 16. And the front-end | tip part 23a contact | abuts from the side to the lowest pillow packaging body 6a (refer FIG.2 (b)), and also the front-end | tip part 23a advances and cross-feeds the lowest pillow packaging body 6a to the discharge port 10b. (See FIG. 2 (c)).

  Thereafter, the leading end 23a continues to advance and pushes and moves the lower end of the swinging fastener 15 together with the lowermost pillow packaging body 6a (see FIG. 2D), and the swinging sensor 15a is turned off. When the lowermost pillow packaging body 6a almost comes out of the discharge port 10b, the second pillow packaging body 6b from the bottom is detached from the lowermost pillow packaging body 6a and transfers to the outer peripheral surface of the extrusion member 23 (FIG. 3). (See (a)). At that time, the second pillow packaging body 6b is transferred to the centrifugal portion outer circumferential surface 23b close to the distal end portion 23a in the outer circumferential surface of the extrusion member 23, and the height thereof is the height of the upper surface of the lowest pillow packaging body 6a. Since there is no great difference, the second pillow package 6b gently moves from the lowest pillow package 6a to the pushing member 23.

  Further, when the pushing member 23 rotates and the tip 23a advances to the vicinity of the discharge port 10b (see FIG. 3B), the lowermost pillow packaging body 6a comes off the swinging fastener 15 and falls by its own weight. At the same time, the outer peripheral surface of the push-out member 23 that supports the second pillow package 6b shifts from the centrifugal outer peripheral surface 23b to the intermediate outer peripheral surface 23c. Then, when the lowest pillow package 6a is discharged rearward from the discharge port 10b (see FIG. 3C), it is detected by the discharge sensor 26, and at that time, from the second The outer peripheral surface of the push-out member 23 that supports the lowest pillow package 6b is transferred from the intermediate outer peripheral surface 23c to the mesial outer peripheral surface 23d. Further, the lower end portion of the swinging fastener 15 has been separated from the pillow packaging body 6a and returned to the discharge port 10b until then, and the urging force is a frictional force between the outer peripheral surface of the pushing member 23 and the lower surface of the pillow packaging body 6b. Therefore, the pillow package 6b does not exit from the discharge port 10b and remains in the storage space 10a. Further, since the swing sensor 15a returns from OFF to ON when the lower end of the swing fastener 15 returns to the discharge port 10b, the detection sequence of the discharge operation of the pillow package 6a by the swing sensor 15a is completed.

Finally (see FIG. 3D), the pushing member 23 finishes one rotation and returns to its original position. When the pushing member 23 comes under the inner bottom portion 16 including the outer peripheral surface, the bottom is reached. The pillow package 6b is transferred from the mesial portion outer peripheral surface 23d of the pushing member 23 to the upper surface of the inner bottom portion 16.
Thus, when descending in the process from the second to the bottom, the pillow packaging body 6b moves from the upper surface of the pillow packaging body 6a to the centrifugal outer peripheral surface 23b, the intermediate outer peripheral surface 23c, and the mesial outer peripheral surface of the pushing member 23. 23d to the inner bottom portion 16 in that order, but the outer peripheral surface of the extruding member 23 is formed so that the height of the supporting member of the outer peripheral surface of the extruding member 23 is gradually reduced. Also, the other pillow package 6 stacked thereon gently descends.
Also, if either the swing sensor 15a or the discharge sensor 26 fails, an abnormality is determined, the operation of the chemical cassette 10 is stopped, and if there is a buzzer or the like, an alarm sound is emitted, an alarm lamp or the like. If there is, it will flash.

  About the Example 2 of the chemical | medical agent cassette of this invention, the specific structure is demonstrated with reference to drawing. FIG. 4 shows some structural examples of the push-out member 23, wherein (a) to (d) are perspective views and (e) to (f) are side views.

In the push-out member 23 shown in FIG. 4B, the tip end portion 23a and the centrifuge portion outer peripheral surface 23b are separated into two, but the intermediate portion outer peripheral surface 23c and the mesial portion outer peripheral surface 23d are connected and integrated. Yes.
The extruded member 23 shown in FIG. 4C is a single extruded member 23, but the length in the axial direction is longer.

The pushing member 23 shown in FIG. 4 (d) has two pushing members 23 mounted on the support shaft 22 as in FIG. 4 (a). The position (phase angle) of the portion 23a is fixed in a state of being clearly deviated.
The pushing member 23 shown in FIG. 4 (e) is obtained by integrating two pushing members 23 that are point-symmetric and anti-symmetric so that the pushing members 23 work alternately every half rotation of the support shaft 22. It has become.
The pushing member 23 shown in FIG. 4 (f) is obtained by integrating three pushing members 23 arranged radially, and the pushing member 23 works in order every 1/3 rotation of the support shaft 22. ing.

In the above embodiment, the support shaft 22 and the extrusion member 23 are separate from each other, and the structure example in which the extrusion member 23 is externally fitted to the support shaft 22 is illustrated. However, they may be integrally formed. It may be integrated by welding or the like.
In the above embodiment, the transmission member is the gear 25, but other members such as a belt may be used, and the transmission gear 25 may be omitted and the support shaft 22 and the electric motor 24 may be directly connected.

  In the above-described embodiment, the shaft rotation of the support shaft 22 is stopped upon completion of the discharge of the lowermost pillow package body 6a. You may make it stop the axial rotation of the spindle 22 after discharging a plurality, without stopping. Further, in order to accurately set the rotation stop position of the support shaft 22 and the push-out member 23, for example, origin sensors are sequentially provided in the discharge mechanisms 21 to 26, and the rotation position of the push-out member 23 is confirmed based on the detection result. It is good to do so.

  The PTP cassette of the present invention can be used alone, or can be detachably incorporated into part or all of the medicine dispensing apparatus (see, for example, Patent Documents 1 to 4).
