Description

  The present invention relates to a medicine take-out mechanism of a dispensing device, and is particularly suitable for a dispensing device that automatically puts a packaged tablet called a PTP (press-through package) tablet sheet into a tablet cassette.

  Traditionally, pharmacists perform dispensing work in pharmacies such as hospitals according to doctors' prescriptions, but in general hospitals where medical fields are wide, there are many types of tablets that can be taken out at all times, and storage locations are limited. Not only was it necessary, but the work of dispensing based on prescriptions was very mentally and physically burdensome.

  Accordingly, a dispensing device has been developed that automatically dispenses a predetermined number of predetermined tablets including a fraction of a PTP tablet sheet based on a preset program (see, for example, Patent Documents 1 and 2). In such a conventional adjustment device, a plurality of PTP tablet sheets are stacked in the vertical direction and stored in the tablet cassette, and the lowest PTP tablet sheet is dispensed one by one.

  The PTP tablet sheet is a packaging form in which the tablet is taken out by breaking the bottom aluminum sheet part by pressing the tablet side. Generally, 10 or more tablets are made into one sheet. To be supplied.

  FIG. 7 is a diagram showing the configuration of the PTP tablet sheet 900, where (a) is a plan view and (b) is a side view. As shown in FIGS. 7 (a) and 7 (b), the surface 910 of the PTP tablet sheet 900 is formed with pockets 920 each containing a tablet, and the pocket 920 faces upward in the tablet cassette. Thus, each PTP tablet sheet 900 is accommodated, and usually, one end side in the longitudinal direction is provided with an ear portion 930 for chucking with a chucking device. It was.

  On the other hand, the PTP tablet sheet 900 is sold in a box by a manufacturer or the like, and is taken out from the box and filled in a tablet cassette. The box stores the PTP tablet sheet 900 with the pocket forming surfaces facing each other. For this reason, in the conventional dispensing device, when the PTP tablet sheet 900 is transferred from the box to the tablet cassette, the work of aligning the orientation of the PTP tablet sheet 900 is required, which is troublesome.

  Moreover, in the conventional dispensing device, since all the PTP tablet sheets 900 are aligned so that the pockets 920 face upward, the number of sheets stored in the tablet cassette is small. For this reason, it is necessary to frequently fill the tablet cassette with the PTP tablet sheet 900, and when a prescription with a large number of sheets is applied, the dispensing operation is performed for filling the tablet cassette with the PTP tablet sheet 900. There was a problem that could be interrupted.

  Furthermore, in the conventional dispensing device, since the PTP tablet sheets 900 are dispensed one by one from the tablet cassette, the dispensing speed of the PTP tablet sheets 900 is slow. For this reason, when a prescription with a large number of sheets is applied, there is a problem that it takes time to pay out.

  FIG. 8 is an explanatory view showing the operation of taking out the PTP tablet sheet in the improved technology of the conventional dispensing device. FIG. 8A shows a case where two PTP tablet sheets are taken out simultaneously, and FIG. Each of the cases where the PTP tablet sheet is left behind is shown. Here, based on the problems of the conventional dispensing device, as shown in FIG. 8A, the PTP tablet sheets 900 (901, 902, 903, 904,...) Face each other with their pocket forming surfaces. In this way, two sheets are stacked in the vertical direction in the tablet cassette, and one set of PTP tablet sheets 901 and 902 at the bottom of the tablet cassette is simultaneously dispensed by the extrusion member 5515. (For example, refer to Patent Document 3). 8A indicates the direction in which a load is applied by the PTP tablet sheets 903, 904,..., And B indicates the moving direction of the pushing member 5515.

  The partition piece 5313 is installed so that the second set (set) of the PTP tablet sheets 903 and 904 does not pop out at the time of the payout, and the guideline of the installation is the overlapping height H of the PTP tablet sheets 901 and 902. About 1.5 times.

  However, as shown in FIG.8 (b), the load by the PTP tablet sheet | seat 903,904, ... located above is added to the A direction at the rear end of PTP tablet sheet | seat 901,902 taken out from a tablet cassette. For this reason, the PTP tablet sheet 902 rotates in the C direction with the pocket at the rear end of one of the PTP tablet sheets 901 and 902 taken out as a fulcrum. Then, the pockets of the PTP tablet sheets 901 and 902 are separated from each other. In a state where the pockets of the PTP tablet sheets 901 and 902 are separated from each other, the PTP tablet sheet 901 is further pushed out in the B direction by the extrusion member 5515. Then, the PTP tablet sheets 901 and 902 are separated, and only the PTP tablet sheet 901 is taken out of the tablet cassette, but the PTP tablet sheet 902 remains there without being taken out of the tablet cassette. As a result, the PTP tablet sheets 901, 902,... Cannot be supplied in a large amount and stably.

  This invention is made | formed in view of such a situation, and it aims at providing the chemical | medical agent extraction mechanism of the dispensing apparatus which can supply a chemical | medical agent sheet in large quantities and stably.

The present invention provides a medicine cassette for storing medicine sheets in which pockets containing medicines are arranged on one side so as to be stacked in a setting direction from a reference surface, and a medicine sheet stored in the medicine cassette. A take-out unit that takes out in order from the one closest to the reference surface, and in the medicine cassette, the one side of the medicine sheet is arranged opposite to each other so that the pockets do not overlap each other, Each set of two sheets is stored in the set, and the take-out unit is configured to take out the set of two sets of stored medicine sheets out of the set of drug sets in units or multiples of the set. A drug take-out mechanism of a dispensing device, wherein the take-out port is partially blocked by a take-out port of a drug sheet formed in the drug cassette. Includes a partition portion, on the downstream side of the take-out direction of the drug sheet than specification switching portion of this, and a separation preventing part for preventing the separation of the drug between the sheets which Ri issued preparative, the separation prevention unit, said medicament to be taken The sheet is brought into contact with the sheet from the side opposite to the reference surface and the opening angle between the drug sheets to be taken out is regulated to prevent separation of the medicine sheets to be taken out. . The drug includes tablets, capsules and the like.

According to the present invention, the outlet of the medicament sheet formed into drug cassettes, and a partition portion for closing the removal port partially downstream of the take-out direction of a medicament sheet than specification switching section of this, taken A separation preventing unit that prevents separation of the medicine sheets that are ejected, the separation preventing part contacting the medicine sheet to be taken out from the side opposite to the reference surface, and By restricting the opening angle of the medicine sheet, separation of the medicine sheets to be taken out is prevented, so that a load or the like by another medicine sheet is applied to the rear end of the medicine sheet taken out through the partition portion, and the medicine to be taken out is removed. Even if the front edge of one drug sheet rotates relative to the other drug sheet with the pocket at the end of the sheet as a fulcrum, the opening angle between the drug sheets due to the rotation is Is control. Then, the pockets of the medicine sheet are not separated from each other. Therefore, even if the medicine sheet is further pushed out, the medicine sheets are not separated from each other, and a part of the medicine sheet is not taken out of the medicine cassette and remains there. In this way, separation of the drug sheets taken out from the outlet can be prevented, and the drug sheets can be taken out of the drug cassette in units of sets or multiples of the set. As a result, a large amount of drug sheet can be stably supplied.

  Moreover, it is preferable that the said separation prevention part is located in the reference plane side rather than the said partition part.

  In this case, since the separation preventing part is located closer to the reference surface than the partition part, the opening angle between the drug sheets is further reduced. Then, the pockets of the medicine sheet are not separated from each other, and separation of the medicine sheets taken out from the outlet can be reliably prevented.

  Moreover, it is preferable that the said separation prevention part is integrally formed with the said partition part.

  In this case, since the separation preventing part is integrally formed with the partition part, the number of parts can be reduced.

  Moreover, it is preferable to form a smooth surface between the partition part and the separation preventing part.

  In this case, since a smooth surface is formed between the partition part and the separation preventing part, it is possible to prevent the drug sheet taken out from the outlet from being caught.

  Moreover, it is preferable that a separation preventing means for preventing separation of the medicine sheets to be taken out is further provided downstream of the taking-out port in the taking-out direction of the medicine sheet.

  Since the apparatus further includes separation preventing means for preventing separation of the medicine sheets to be taken out from the take-out port in the downstream direction in the taking-out direction of the medicine sheet, As a result, separation of the drug sheets taken out from the outlet can be more reliably prevented.

  According to the present invention, at the outlet of the medicine sheet formed in the medicine cassette, the partition part that partially closes the outlet, and the take-out part that is downstream of the partition part in the direction of taking out the medicine sheet. And a separation preventing part for preventing separation of the medicine sheets to be removed, so that the rear end of the medicine sheet taken out through the partitioning portion is subjected to a load by another medicine sheet, and the last end of the medicine sheet to be taken out. Even if the front end of one drug sheet rotates with respect to the other drug sheet with the pocket at the center as a fulcrum, the opening angle between the drug sheets due to the rotation is regulated by the separation preventing unit. Then, the pockets of the medicine sheet are not separated from each other. Therefore, even if the medicine sheet is further pushed out, the medicine sheets are not separated from each other, and a part of the medicine sheet is not taken out of the medicine cassette and remains there. In this way, separation of the drug sheets taken out from the outlet can be prevented, and the drug sheets can be taken out of the drug cassette in units of sets or multiples of the set. As a result, a large amount of drug sheet can be stably supplied.

(Embodiment 1)
FIG. 1 is an exploded perspective view showing main components of a dispensing device 1 according to Embodiment 1 of the present invention.

  As shown in FIG. 1, the dispensing device 1 includes two Y carriages 200 and 200 provided on the left and right sides of the box-shaped device main body 100, and X carriages supported by the Y carriages 200 and 200, respectively. 300, 300, take-out units 400, 400 supported by these X carriages 300, 300, and two on the front left and right sides of the apparatus main body 100, and a plurality of tablet cassettes (corresponding to drug cassettes). 500, 500,... Are arranged below the left and right cassette shelves 600, 600 across the left and right ends of both cassette shelves 600, 600. And a transport conveyor unit 800 of the table.

  Hereinafter, representative components of a plurality of components will be described. The Y carriage 200 includes a servo motor 210, a ball screw 220 in the vertical axis direction (Y direction in FIG. 1) driven by the servo motor 210, vertical guides 230 and 230 respectively disposed on the left and right of the ball screw 220, The X carriage 300 includes a carriage main body 310 that moves up and down together with the nut 240 by the rotation of the ball screw 220 while being guided by the vertical guides 230 and 230, and the carriage main body. On 310, a servo motor 410, a ball screw 415 in the horizontal axis direction (X direction in FIG. 1) driven by the servo motor 410, and a nut (not shown) are provided.

  FIG. 2 is a perspective view showing the configuration of the tablet cassette 500 according to the first embodiment. In FIG. 2, unless otherwise specified, the front side facing the take-out unit 400 of the tablet cassette 500 is referred to as the front side, the back side is referred to as the rear side, and the left side and the right side are viewed from the front side to the rear side. (The same applies to FIGS. 4 and 6 described later).

  The tablet cassette 500 in the first embodiment is formed to be slightly wider than various PTP tablet sheets (corresponding to drug sheets) 900 to be stacked. Therefore, as the tablet cassette 500, not only the same one but also a plurality of different ones having only width dimensions are prepared according to the widths of the various PTP tablet sheets 900. As shown in FIG. 2, the specific configuration thereof includes a long cassette base 510 having a concave cross section and a cassette body 520 that is detachably fitted from the longitudinal direction of the cassette base 510. ing.

  The cassette base 510 includes a mounting portion (not shown) for attaching the cassette shelf 600 to the shelf plate 602, so that the tablet cassette 500 having the same width dimension as well as the tablet cassette 500 having a different width dimension can be used. Also, it can be arranged at an arbitrary position in the width direction.

  The cassette body 520 is mounted on the cassette base 510 at the upper portion 530 of the main body 530 on which a plurality of PTP tablet sheets 900 (901, 902,. The main body lower portion 540 is formed.

  The main body lower part 540 is arranged in an assembled state with the cassette base 510 of the cassette main body 520 and is embedded in the cassette base 510, but when viewed as a single unit, the main body lower part 540 has a long shape with a concave cross section. An extrusion mechanism 550 for taking out as a set the PTP tablet sheets 901 and 902 loaded on the bottom of the main body upper part 530 and immediately above it is provided in the housing.

  The main body upper part 530 has an L-shape in a side view and is projected from the middle part to the front part so as to protrude above the cassette base 510 in the assembled state of the cassette body 520 to the cassette base 510. The side walls 5311 and 5312 are bent inward from each other at the front end to be opposed to each other with a predetermined gap, thereby forming a front wall 531. The upper ends of the left and right side walls 5311 and 5312 are connected to each other by a reinforcing plate 532.

  By the way, the PTP tablet sheets 901, 902,... Stacked in the main body upper part 530 of the tablet cassette 500 are the PTP tablet sheets 901, 902 loaded first, and the PTP tablet sheet 903 loaded next. , 904, the lower side of the set, so that the set of PTP tablet sheets 901, 902 loaded first is taken out before the set of PTP tablet sheets 903, 904 loaded next. First-in, first-out in units.

  For this reason, each set of PTP tablet sheets 901 and 902 at the bottom of the main body upper part 530 of the tablet cassette 500 is taken out of the main body upper part 530, but the PTP tablet sheets 901 and 902 are set. And a set of PTP tablet sheets 901 and 902 on the bottom and a set of PTP tablet sheets 903 and 904 on the upper side are simultaneously removed from the upper portion 530 of the main body by friction between the PTP tablet sheets 903 and 904 So-called multiple removal may occur.

  Therefore, in the first embodiment, in order to prevent multiple removal of the PTP tablet sheets 901, 902,... Stored in the tablet cassette 500 in sets of two, the upper portion 530 of the main body 530 of the tablet cassette 500 is prevented. A PTP tablet sheet 904 at a position higher than the even-numbered set position of the fourth or more sheets counted from the bottom PTP tablet sheet 901 on the bottom plate (corresponding to a bottom surface and a reference surface) 5301. Is provided with a partition piece 5313 that prohibits the tablet from being taken out of the tablet cassette 500.

  FIG. 3 is a configuration diagram of the partition piece 5313 in the first embodiment, where (a) is a perspective view, (b) is a front view, and (c) is a right side view. As shown in FIGS. 3A to 3C, the partition piece 5313 has an elongated rectangular shape in front view, but an elongated hole 5313 e in the vertical direction is formed from the upper part of the L-shaped main body 5313 d to the middle part. In the lower part, a block 5313b having an L-shaped longitudinal section is screwed with two screws 5313f and 5313f. The block 5313b is made of, for example, a synthetic resin so as not to damage the PTP tablet sheet 904 when the PTP tablet sheet 904 comes into contact. Further, the block 5313b is located in a partition 5313c with which the PTP tablet sheets 904,... Abut, and in front of the partition 5313c (corresponding to the downstream side in the direction of taking out the medicine sheet), and the partition 5313c. And a separation preventing unit 5313a for preventing separation of the PTP tablet sheets 901 and 902 taken out through the device. Further, a smooth surface 5313g is formed between the partition portion 5313c and the separation preventing portion 5313a so that the PTP tablet sheets 901 and 902 are not caught there.

  Here, depending on the types of PTP tablet sheets 901, 902,..., The sheet interval varies greatly due to the difference in pocket height and the like, so it is not preferable to make the height position of the partition piece 5313 constant. Therefore, a convex member 5314 is attached to the left side of the front surface of the front wall 531 of the tablet cassette 500. The partition piece 5313 is attached to the convex member 5314 by inserting two screws (not shown) into the elongated hole 5313e.

  Therefore, the partition piece 5313 can set the height position of the partition piece 5313 by loosening the two screws and sliding the main body 5313d in the vertical direction along the convex member 5314. Here, the partition portion 5313c of the partition piece 5313 is a height at which the fourth PTP tablet sheet 904 can come into contact with the PTP tablet sheet 900 at the bottom on the bottom plate 5301 of the upper body 530 of the tablet cassette 500. Set to the position. For example, the height between the PTP tablet sheets 901 and 902 may be set to 2 × 2 to several mm.

  Further, the height of the separation preventing portion 5313a is set to a position slightly lower than the height of the partition portion 5313c and higher than the height between the PTP tablet sheets 901 and 902. The smooth surface 5313g is formed by, for example, connecting the partition portion 5313c and the separation preventing portion 5313a with an appropriate rounded surface and a forwardly inclined surface. Then, at the outlet 5318, the opening angle between the PTP tablet sheets 901 and 902 is restricted, and the pockets are less likely to be separated from each other.

  In this way, it is easy to determine the set value of the partition piece 5313 by partially closing the outlet 5318 formed below the front wall 531 of the tablet cassette 500 with the partition piece 5313 from the top to the bottom. Become. And, with a simple configuration, the multiple take-out from the take-out port 5318 is surely prevented, and separation of the sheets taken out from the take-out is surely prevented, so that a large amount of PTP tablet sheets 901, 902,. And can be taken out.

  It is not necessary to adjust the position of the partition piece 5313 in the left-right direction. The PTP tablet sheet 900 at the even-numbered setting position from the bottom with which the partition piece 5313 comes into contact has the pocket 920 facing downward, so that the partition piece 5313 purposely makes contact with the pocket 920 while avoiding it. It is not necessary. However, when it comes into contact with the second PTP tablet sheet 902, the pocket 920 obstructs the removal of the lowermost PTP tablet sheet 901. This is the reason for setting the even-numbered setting position of the fourth or more sheets.

  As shown in FIG. 1, the take-out unit 400 includes a Z carriage 411 extending forward (Z direction in FIG. 1) from the carriage body 310, and payout plates 430, 430 arranged to be movable forward and backward with the Z carriage 411. And a pusher 440 disposed on the side facing the tablet cassette 500 of one of the payout plates 430 and 430 (right side in FIG. 1). In addition, when the payout plates 430 and 430 are in a horizontal posture, each tip is inclined so as to be lowered first (see FIG. 5 described later).

  The advancing and retracting operations of the payout plates 430 and 430 are performed by rotationally driving a ball screw (not shown) by the servo motor 420, and the opening / closing operation is performed by driving a stepping motor (not shown). . A primary bucket 450 is provided below the payout plates 430 and 430, and a secondary bucket 480 with a shutter 470 is further provided below the primary bucket 450.

  Hereinafter, the dispensing operation of the PTP tablet sheet 900 (901, 902, 903, 904,...) From the tablet cassette 500 by the dispensing device 1 of Embodiment 1 will be schematically described. FIG. 4 is an explanatory view showing the function of the partition piece 5313 in the first embodiment, and (a) is a side sectional view showing a state when the lowermost set of PTP tablet sheets 901 and 902 passes through the partition piece 5313. (B) is a sectional side view which shows a state when extruding the PTP tablet sheet 901,902, ... of (a).

  Now, as shown in FIG. 4 (a), two PTP tablet sheets 901, 902,... Are set in the tablet cassette 500 so that the pockets 920, 920,. (It is in a state where it is taken out from a commercially available box, and between the upper and lower PTP tablet sheets 901 and 902, the ears 930 and 930 are reversed in the front-rear direction and in the opposite directions.) In addition, it is assumed that the pushing member 5515 comes into contact with the rear end of the PTP tablet sheet 901 at the lowest position.

  At this time, it is assumed that the take-out unit 400 is in a position facing the front side of the tablet cassette 500, and the dispensing plates 430 and 430 are in a horizontal posture together with the pusher 440 attached to one of them.

  First, by driving the servo motor 420 of the take-out unit 400, the dispensing plates 430 and 430 are moved toward the front side of the tablet cassette 500. Eventually, the pusher 440 attached to one of the dispensing plates 430 and 430 directly presses a member (not shown) of the tablet cassette 500. Then, with the action of the pushing mechanism 550, the pushing member 5515 in FIG. 4A moves forward, and the pushing member 5515 in FIG.

  At this time, the pushing member 5515 pushes the PTP tablet sheets 901 and 902 forward from the main body upper part 530 of the tablet cassette 500. Then, the front end of the set of PTP tablet sheets 901 and 902 can pass under the partition portion 5313c formed on the lower rear side of the block 5313b of the partition piece 5313. On the other hand, with respect to the front end of the set of PTP tablet sheets 903 and 904, the upper PTP tablet sheet 904 abuts on the partition portion 5313c, and the front end of the set of PTP tablet sheets 903 and 904 passes under the partition portion 5313c. Stop.

  Then, the rear ends of the two PTP tablet sheets 901 and 902 that have passed under the partition portion 5313c are pressed against the front ends of the set of PTP tablet sheets 903 and 904, and the front ends of the PTP tablet sheets 901 and 902 are opened. However, the opening angle is restricted by the separation preventing portion 5313a formed on the lower front side of the block 5313b of the partition piece 5313. Therefore, since the pockets of the PTP tablet sheets 901 and 902 remain engaged with each other, the PTP tablet sheets 901 and 902 are not completely separated from each other, and are moved onto the dispensing plates 430 and 430 of the take-out unit 400 as they are set. . In this manner, the PTP tablet sheets 901 and 902 can be dispensed by the take-out unit 400 and taken out from the tablet cassette 500.

  When the set of PTP tablet sheets 901 and 902 is taken out, the discharge plates 430 and 430 of the take-out unit 400 receive the PTP tablet sheets 901 and 902 together with the pusher 440 and return to their original positions. 5515 also returns to the original end. At the time of this return, the pushing member 5515 is pulled back under the next set of PTP tablet sheets 903 and 904 and enters a standby state.

  Next, for example, by driving a stepping motor (not shown), the dispensing plates 430 and 430 are rotated in opposite directions around the rotation axis and opened downward, and the PTP tablet sheets 901 and 902 taken out from the tablet cassette 500 are opened. It can be dropped into the primary bucket 450. The primary bucket 450 is moved onto the secondary bucket 480 using the X carriage 300 and the Y carriage 200.

  Then, a bottom shutter (not shown) of the primary bucket 450 is opened, and the PTP tablet sheets 901 and 902 are dropped into the secondary bucket 480. Next, the bottom shutter 470 of the secondary bucket 480 is opened, and the PTP tablet sheets 901 and 902 are dropped onto the transport conveyor unit 800.

  The conveyor unit 800 includes a group of rollers 801 and tablet takeout buckets 802 and 802 that are moved in the front-rear and left-right directions by the group of rollers 801. Then, the PTP tablet sheets 901 and 902 dropped from the secondary bucket 480 via the shutter 470 fall into one of the tablet takeout buckets 802 and 802.

  The PTP tablet sheets 901 and 902 that have fallen into one of the tablet take-out buckets 802 and 802 are further moved to a predetermined site while being stored in the tablet take-out buckets 802 and 802, and are discharged from there.

  As described above, the dispensing device 1 of the first embodiment disposes the PTP tablet sheets 901, 902,... In the tablet cassette 500 so as to face each other with their pockets not overlapping each other. , The PTP tablet sheets 901, 902,... Are stored in sets of two, and the takeout unit 400 stores the PTP tablet sheets 901, 902,. Is configured to be taken out of the tablet cassette 500 as a set unit, and the outlet 5318 is provided in the outlet 5318 of the PTP tablet sheets 901, 902, ... formed on the front wall of the tablet cassette 500. A partition portion 5313c of a partition piece 5313 that is partially closed, and a method of taking out the PTP tablet sheets 901, 902,... From the partition portion 5313c Since the separation prevention part 5313a for preventing the separation of the PTP tablet sheets 901 and 902 taken out is provided on the downstream side, the separation of the PTP tablet sheets 901 and 902 taken out from the outlet 5318 can be prevented. The PTP tablet sheets 901, 902,... Can be reliably taken out of the tablet cassette 500 in units of sets. As a result, the PTP tablet sheets 901, 902, ... can be supplied in a large amount and stably.

(Embodiment 2)
By the way, in the said Embodiment 1, although it can respond only with the shape of the partition piece 5313 of the tablet cassette 500, the surface 5313g which connects the partition part 5313c and the separation prevention part 5313a by the shape of the block 5313b of the partition piece 5313, etc. There are certain restrictions because the inclination angle (downward) is determined.

  That is, if this inclination angle is set large, the frictional resistance on the surface 5313g becomes large, and it becomes difficult for the PTP tablet sheets 901 and 902 to pass through. On the other hand, if this inclination angle is set to a small value, the size of the block 5313b in the front-rear direction increases, and the maximum length of the PTP tablet sheets 901, 902,. , It protrudes from the tablet cassette 500 and easily interferes with the take-out unit 400. Further, when the thickness of the set of PTP tablet sheets 901, 902,... Filled in the tablet cassette 500 changes significantly, it is necessary to adjust the height position of the partition piece 5313, which is troublesome.

  Therefore, in the second embodiment, the separation prevention plate (corresponding to the separation prevention means) provided at a predetermined interval from the upper surfaces of the payout plates (corresponding to the separation prevention means) 430, 430 of the take-out unit 400. 435 is further provided.
