Description

  The present invention relates to a drug stock structure of a dispensing device, and is particularly suitable for a drug stock structure of a dispensing device that automatically dispenses 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). 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.

  In the conventional dispensing 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.

  FIG. 9 is a diagram showing a general configuration of the PTP tablet sheet 900, in which (a) is a plan view and (b) is a side view. FIG. 10 and FIG. 11 are explanatory views showing the push-out operation of the PTP tablet sheet 900 in the conventional dispensing device.

  As shown in FIGS. 9 (a) and 9 (b), the surface 910 of the PTP tablet sheet 900 is formed with pockets 920 each enclosing 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.

  The PTP tablet sheet 900 is stored in a box and sold by a manufacturer or the like, and is taken out from the box and filled into 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.

  Therefore, the present inventors, as shown in FIG. 10 (a) and FIG. 11 (a), each PTP tablet sheet 900 (901, 902, 903, 904,. 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. It was decided to take. Here, FIG. 10 (a) is a case of PTP tablet sheets 901, 902,... In which each set is combined with the side with and without the ears so that there is no significant shift between the sets. FIG. 11 (a) shows the case of PTP tablet sheets 901, 902,... In which each set has a significant shift in front and back by combining the side with the ears or the side without the ears. It is.

  At the time of this dispensing, only the first set of PTP tablet sheets 901 and 902 are paid out, and the partition piece 5313 is installed so that the second set (set) of the PTP tablet sheets 903 and 904 does not jump out. The standard of the installation is about 1.5 times the overlapping height of the PTP tablet sheets 901 and 902. The sheet pop-out prevention piece 543 is installed so as to be able to protrude and retract from the bottom plate 5301 so that the first set of PTP tablet sheets 901 and 902 does not pop out except during the payout. For example, the sheet pop-out prevention piece 543 protrudes from the bottom plate 5301 when the pushing member 5515 does not press the PTP tablet sheet 901, and when the pushing member 5515 presses the PTP tablet sheet 901, the sheet popping prevention piece 543 comes into contact with the tip of the PTP tablet sheet 901 and falls down. So that it is elastically biased.

  As shown in FIG. 10B, in the case of PTP tablet sheets 901, 902,... In which each set does not have a significant deviation in the front and back, each set passes through the partition piece 5313 before the sheet. The set is lifted from the bottom surface 5301 by the elastic return force of the pop-out preventing piece 543, so that each set can get over the sheet pop-out preventing piece 543 and pass through the partition piece 5313. On the other hand, as shown in FIG. 11 (b), in the case of PTP tablet sheets 901, 902,... Where each set has a significant shift before and after, each set jumps out before passing through the partition piece 5313. In some cases, the elastic restoring force of the prevention piece 543 may cause the surface to rise from the bottom surface 5301 so that it cannot pass through the partition piece 5313.

  The present invention has been made in view of such circumstances, and even if each set is a drug sheet having a significant shift before and after, a dispensing device that can get over the sheet protruding piece and pass through the partitioning piece. It aims to provide a drug stock structure.

The present invention is to heavy sleep by accommodating the medicine sheet having an array of pockets of a medicated on one side based on reference plane, drug dispensing apparatus taken by be out urchin configured externally in order from the closest to the reference plane a stock structure, by facing the one side each other with no overlap pockets between each other before Symbol agent sheet, be housed superimposed on the reference surface as a set of two by two sheets of drug sheet drilled and medicine cassette possible drug sheets stored in the set of one by two, so that it can be taken out in multiples of cell-by-bit basis or the set to the medicine cassette outside apart from the reference plane And a partition piece that is urged in a direction protruding from the reference surface and prevents the drug sheet from jumping out between the partition piece and the reference surface, The upstream side of the partition piece in a direction of extracting agent sheet, a tip portion extending to said reference plane closer than the partition sections by contacting the drug sheets taken out to the medicine cassette outside the is characterized in that a pressing piece for pressing the drug sheet to the reference surface side against the urging force of the sheet pop-out preventing piece. The drug includes tablets, capsules and the like.

According to the present invention, by facing the one side each other with no overlap pockets between each other before Symbol agent sheet, it is housed superimposed on the reference surface as a set of two by two sheets of drug Sheet drilled and medicine cassette possible drug sheets stored in the set of one by two, so that it can be taken out in multiples of cell-by-bit basis or the set to the medicine cassette outside apart from the reference plane a partition member disposed Te, is biased in a protruding direction from the reference plane, the a sheet pop-out preventing piece for preventing the medicament sheet pops out from between the partition pieces and the reference plane, taken out of the drug seat upstream of the partition piece in the direction to be brought into contact with the distal end portion extending to said reference plane closer than the partition sections, the drug sheet is taken out to the medicine cassette out Ri, pressing because a pressing piece for pressing the drug sheet to the reference surface side against the urging force of the sheet pop-out preventing piece, before passing through the partition pieces, a set of drug sheets in this pressing piece By doing so, it is possible to prevent the set of drug sheets from floating from the reference plane.

  As a result, not only a set of drug sheets with no significant shift in the front and back, but also a set of drug sheets with a significant shift in the front and back can pass over the sheet jump prevention piece and pass through the partition piece. Sheets can be sequentially taken out in units of sets or multiples of the set. As a result, a large amount of drug sheet can be stably supplied.

  As in the invention described in claim 2, it is preferable that the pressing piece has flexibility.

  According to invention of Claim 2, since the said press piece has flexibility, before passing through a partition piece, by pressing the set of a medicine sheet with the elastic force of a press piece, of the set of this medicine sheet Lifting can be prevented.

  Or like the invention of Claim 3, it is preferable that the front-end | tip part of the said press piece is attached so that rotation around the base part of this press piece is possible.

  According to the third aspect of the present invention, since the tip of the pressing piece is pivotably attached around the base of the pressing piece, before passing through the partition piece, the weight of the pressing piece (or By pressing the set of drug sheets with the added spring load), it is possible to prevent the set of drug sheets from being lifted.

  According to a fourth aspect of the present invention, it is preferable that the tip end portion of the pressing piece is inclined outward.

  According to invention of Claim 4, since the front-end | tip part of the said press piece inclines outward, it becomes easy to press a chemical | medical agent sheet.

According to the present invention, by facing the one side each other with no overlap pockets between each other before Symbol agent sheet, it is housed superimposed on the reference surface as a set of two by two sheets of drug Sheet drilled and medicine cassette possible drug sheets stored in the set of one by two, so that it can be taken out in multiples of cell-by-bit basis or the set to the medicine cassette outside apart from the reference plane a partition member disposed Te, is biased in a protruding direction from the reference plane, the a sheet pop-out preventing piece for preventing the medicament sheet pops out from between the partition pieces and the reference plane, taken out of the drug seat upstream of the partition piece in the direction to be brought into contact with the distal end portion extending to said reference plane closer than the partition sections, the drug sheet is taken out to the medicine cassette out Ri, pressing because a pressing piece for pressing the drug sheet to the reference surface side against the urging force of the sheet pop-out preventing piece, before passing through the partition pieces, a set of drug sheets in this pressing piece By doing so, it is possible to prevent the set of drug sheets from floating from the reference plane.

  As a result, not only a set of drug sheets with no significant shift in the front and back, but also a set of drug sheets with a significant shift in the front and back can pass over the sheet jump prevention piece and pass through the partition piece. Sheets can be sequentially taken out 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.

  2 is a perspective view showing the configuration of the tablet cassette 500 in the first embodiment, FIG. 3 is a front view of FIG. 2, FIG. 4 is a cross-sectional view taken along line AA in FIG. 3, and FIG. It is a perspective view which shows a structure. In each figure, 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. Shows things.

  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. Accordingly, a plurality of tablet cassettes 500 having different width dimensions are prepared according to the widths of various PTP tablet sheets 900. As shown in FIGS. 2 to 4, the specific configuration thereof is 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. It is made up of.

  The cassette base 510 is provided with a mounting portion (not shown) for attaching the cassette shelf 600 to the shelf plate 602, so that even the tablet cassette 500 having a different width dimension is arranged at an arbitrary position in the width direction. Be able to.

  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 stacked at the bottom of the upper portion 530 of the main body and immediately above the main body 530 and a sheet pop-out prevention piece 543 are provided. As shown in FIG. 5, the sheet pop-out prevention piece 543 has an L shape in a side view, and is supported rotatably around a horizontal axis 5432 at a front end of a support member 5431 fixed to the lower body portion 540. The spring 5433 is elastically biased in the B direction. The sheet pop-out preventing piece 543 protrudes from the bottom plate 5301 when the extrusion member 5515 of the extrusion mechanism 550 does not press the PTP tablet sheet 901, and when the extrusion member 5515 presses the PTP tablet sheet 901, the PTP tablet sheet 901. The PTP tablet sheets 901 and 902 are prevented from jumping out of the tablet cassette 500 except when the PTP tablet sheets 901 and 902 are paid out.

  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. This multiple removal is eliminated by allowing only the bottom set of tablet sheets 901 and 902 to pass through the partition piece 5313.

  However, as shown in FIG. 11 (a), if there is a misalignment between the sets of PTP tablet sheets 901 and 902, the lowermost PTP tablet sheet 901 as shown in FIG. 11 (b). , When it gets over the sheet pop-out prevention piece 543, it floats up from the bottom plate 5301 and cannot pass through the partition piece 5313. Such inconvenience is as described above.

  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. The 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 the reference plane) 5301 is the above-mentioned A partition piece 5313 that prohibits the tablet cassette 500 from being taken out and a pressing piece 5313x are provided.

  The partition piece 5313 is made of a material that is relatively difficult to elastically deform, such as a stainless steel thin plate, while the pressing piece 5313x has a so-called flexibility that is relatively easily deformed elastically, such as plastic or a leaf spring. Made of material.

  As shown in FIGS. 2 to 4, the partition piece 5313 has an oblong shape when viewed from the front, but has a long hole 5316 in the vertical direction from the upper part to the middle part, and the lower part is slightly folded rearward to form the bottom plate 5301. It is a variant extending in the direction approaching (downward).

  The pressing piece 5313x, which is also a rectangular shape in front view, is attached to the left side of the partition piece 5313 via a laterally attaching member 5313y. The tip of the pressing piece 5313x extends further downward than the tip of the partition piece 5313.

  The partition piece 5313 partially closes an opening 5318 formed below the front wall 531 of the tablet cassette 500 from the top to the bottom, and the pressing piece 5313x provided on the upstream side of the partition piece 5313. By pressing the set of PTP tablet sheets 901 and 902 downward before passing through the partition piece 5313 with the elastic force of the above, the lifting of the set of PTP tablet sheets 901 and 902 from the bottom plate 5301 can be prevented. .

  This makes it possible to reliably take out a large amount of PTP tablet sheets 901, 902,. Further, the number of PTP tablet sheets 901, 902,... Taken out from the tablet cassette 500 can be adjusted according to the prescription, which is convenient.

  Here, depending on the type of the PTP tablet sheets 901, 902,..., The sheet interval at the time of compression varies greatly due to the difference in the pocket height, etc., so that each height position of the partition piece 5313 and the pressing piece 5313x. Is not preferable. Therefore, a convex member 5314 is detachably attached to the left side of the front wall 531 of the tablet cassette 500 with a screw 5315. The partition piece 5313 is attached to the convex member 5314 by inserting two screws 5317 and 5317 through the elongated hole 5316.

  Therefore, the partition piece 5313 can set the height position of the partition piece 5313 by loosening the two screws 5317 and 5317 and sliding it up and down along the convex member 5314. The base of the pressing piece 5313x is attached to the partition piece 5313 via an attachment member 5313y. Here, the tip of the partition piece 5313 is a height at which the fourth PTP tablet sheet 904 can contact the PTP tablet sheet 900 counted from the lowest PTP tablet sheet 900 on the bottom plate 5301 of the upper body 530 of the tablet cassette 500. Set to position. For example, the height of the partition piece 5313 may be set to the height between the compressed PTP tablet sheets 901 and 902 × 2 to several mm. The tip of the pressing piece 5313x is set slightly lower than the height position of the tip of the partition piece 5313. However, since the pressing piece 5313x is easily elastically deformed, this set value is not necessarily strict. There is no need.

  Note that it is not necessary to adjust the position of the partition piece 5313 and the pressing piece 5313x in the left-right direction. In the PTP tablet sheet 900 at the even-numbered setting position from the bottom where the partition piece 5313 and the pressing piece 5313x abut, since the pocket 920 faces downward, the partition piece 5313 and the pressing piece 5313x are bothered. This is because it is not necessary to avoid the pocket 920 and make contact. 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 Z carriages 411 and 411 (the front side is not shown in FIG. 1) extending forward (Z direction in FIG. 1) from the carriage body 310, and Z. Dispensing plates 430 and 430 disposed between the carriages 411 and 411 so as to be movable back and forth and openable and closable, and pushers 440 and 440 disposed on the side of the dispensing plates 430 and 430 facing the tablet cassette 500 are provided.

  The advancing and retreating 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 and closing operation is performed by mutually rotating the rotation shafts through the gear train by a stepping motor (not shown). It is configured to perform by rotationally driving in the direction. 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 will be schematically described. FIG. 6 is a diagram schematically showing PTP tablet sheets 901, 902,... Stacked in the tablet cassette 500. FIG. 6A shows a set of PTP tablet sheets 901, 902 in the lowermost part as partition pieces 5313. FIG. FIG. 6B is a side sectional view showing a state when passing through the sheet, and FIG. 5B is a side sectional view showing a state when the PTP tablet sheets 901, 902,.

  Now, as shown in FIG. 6 (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 payout plates 430 and 430 are in a horizontal posture together with the pushers 440 and 440.

  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, one of the pushers 440, 440 of the dispensing plates 430, 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. 6A 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 upper PTP tablet sheet 902 comes into contact with the lower end of the pressing piece 5313x, and the tip thereof is pressed downward, so that the interval with the lower PTP tablet sheet 901 is narrowed and the overlapped height in the compressed state is obtained.

  The set of PTP tablet sheets 901 and 902 in the compressed state is prevented from being lifted from the bottom plate 5301 and can pass through the partition piece 5313. On the other hand, for the set of PTP tablet sheets 903 and 904, the upper PTP tablet sheet 904 comes into contact with the lower part of the partition piece 5313, and the set of PTP tablet sheets 903 and 904 is prevented from passing through the partition piece 5313.

  Then, the two PTP tablet sheets 901 and 902 that have passed through the partition piece 5313 drop by gravity onto the payout plates 430 and 430 of the take-out unit 400. 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 pushers 440 and 440 and return to the original positions. The pushing member 5515 also returns to the original last part. 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, by driving a stepping motor (not shown) to rotate the dispensing plates 430 and 430 in opposite directions around the rotation axis and opening them downward, the PTP tablet sheets 901 and 902 taken out from the tablet cassette 500 are removed. 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, according to the first embodiment, in the tablet cassette 500, one side of the PTP tablet sheets 901, 902,... PTP tablet sheets 901, 902,... Are stored as a set of two sheets, and PTP tablet sheets 901, 902,. The opening 5318 formed in the front wall 531 of the tablet cassette 500 is partially blocked by the partition piece 5313 so that the tablet cassette 500 is taken out of the tablet cassette 500 in units of multiples of the tablet cassette 500 and from the partition piece 5313 on the upstream side of the partition piece 5313. Since a flexible pressing piece 5513x that can close the side of the opening 5318 close to the bottom plate 5301 is provided, the partitioning piece 5313 is passed through. Before exiting, by pressing a set of PTP tablet sheets 901, 902 by the elastic force of the pressing piece 5313x downwards, can be prevented from rising from the bottom plate 5301 of the set of PTP tablet sheets 901 and 902.

  As a result, not only a set of PTP tablet sheets 901, 902,... Without significant deviation in the front and back, but also a set of PTP tablet sheets 901, 902,. The PTP tablet sheets 901, 902,... Can be sequentially taken out to the outside in units of sets or multiples of the set because the pop-up prevention pieces 543 can be passed over the partition pieces 5313. As a result, the PTP tablet sheets 901, 902, ... can be supplied in a large amount and stably.

(Embodiment 2)
Since the dispensing device 1 according to the second embodiment of the present invention is substantially the same as that of the first embodiment, the same elements as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The difference from the first embodiment is mainly described.

  FIG. 7 is a perspective view illustrating a configuration of the tablet cassette 500 according to the second embodiment.

  In the second embodiment, in order to prevent multiple removal of the PTP tablet sheets 901, 902,... Stored in the tablet cassette 500 in sets of two, a bottom plate ( This corresponds to the reference plane.) The PTP tablet sheet 904 at a position higher than the even-numbered set position of the fourth or more sheets counting from the PTP tablet sheet 901 at the bottom on 5301 is the tablet cassette. 500 is provided with a partition piece 5313 and a pressing piece 5313x ′ that are prohibited from being taken out to the outside.

  The partition piece 5313 is made of a material that is relatively difficult to elastically deform, such as a stainless steel thin plate, for example, but the material of the pressing piece 5313x ′ is not necessarily a material that is hardly elastically deformed. If the material of the pressing piece 5313x ′ is a material that is easily elastically deformed similar to the pressing piece 5313x of the first embodiment, the configuration is the same as that of the pressing piece 5313x of the first embodiment, and the same functions and effects. Will be played.

  As shown in FIG. 7, the partition piece 5313 has a long rectangular shape in front view, as in the first embodiment, but has an elongated hole 5316 in the vertical direction from the upper part to the middle part, and the lower part on the rear side. It is an irregular shape that is slightly folded and extends in a direction approaching the bottom plate 5301 (downward).

  The pressing piece 5313x ', which is also a rectangular shape in front view, is attached to the left side of the partition piece 5313 via a laterally attaching member 5313y'. The base of the pressing piece 5313x 'is rotatable around the mounting member 5313y', and the tip of the pressing piece 5313x 'extends further downward than the tip of the partition piece 5313. And in order to make it easy to press down the PTP tablet sheet which contacts from the tip part of the pressing piece 5313x ′ to the intermediate part (lower part), the lower part protrudes slightly diagonally forward (outward). did. However, depending on the case, the pressing piece 5313x 'may have a straight shape.

  Here, depending on the type of the PTP tablet sheets 901, 902,..., The sheet interval at the time of compression varies greatly due to differences in the pocket height, etc., so the height position of the tip of the pressing piece 5313x ′ is constant. This is not preferable as in the first embodiment. Accordingly, the height of the tip of the pressing piece 5313x ′ can be adjusted together with the tip of the partitioning piece 5313. Here, the tip of the partition piece 5313 is a height at which the fourth PTP tablet sheet 904 can contact the PTP tablet sheet 900 counted from the lowest PTP tablet sheet 900 on the bottom plate 5301 of the upper body 530 of the tablet cassette 500. The position is set so that the tip of the pressing piece 5313x ′ is set slightly lower than the partition piece 5313. Since the pressing piece 5313x 'can be rotated around the attachment member 5313y', the set value is not necessarily strict.

  In this way, the partition 5313 partially closes the opening 5318 formed below the front wall 531 of the tablet cassette 500 from the top to the bottom, and on the upstream side of the partition 5313, the attachment member 5313y. 'Put the set of PTP tablet sheets 901 and 902 downwards before passing through the partition piece 5313 by the weight of the pressing piece 5313x' provided so as to be rotatable around (or a spring load added thereto). This prevents the PTP tablet sheets 901 and 902 from being lifted from the bottom plate 5301 of the set. Further, since the lower end of the pressing piece 5313x ′ provided on the upstream side of the partitioning piece 5313 is inclined outward by approximately 45 degrees, the setting values of the partitioning piece 5313 and the pressing piece 5313x ′ can be easily determined. It becomes. In addition, with a simple configuration, multiple take-out can be reliably prevented, and a large amount of PTP tablet sheets 901, 902, ... can be taken out stably. Further, the number of PTP tablet sheets 901, 902,... Taken out from the tablet cassette 500 can be adjusted according to the prescription, which is convenient.

  It is not necessary to adjust the position of the pressing piece 5313x ′ in the left-right direction. The PTP tablet sheet 900 at the even-numbered setting position from the bottom with which the pressing piece 5313x ′ comes into contact has the pocket 920 facing downward, so that the pressing piece 5313x ′ avoids the pocket 920. This is because there is no need to abut. 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.

  Hereinafter, the dispensing operation of the PTP tablet sheet 900 (901, 902, 903, 904,...) From the tablet cassette 500 by the dispensing device 1 will be schematically described. FIG. 8 is a diagram schematically showing PTP tablet sheets 901, 902,... Stacked in the tablet cassette 500 according to the second embodiment, and (a) shows the lowermost PTP tablet sheets 901, 902. FIG. Side sectional view showing a state when the set passes through the partition piece 5313 and the pressing piece 5313x ′, (b) is a side sectional view showing a state when the PTP tablet sheets 901, 902,. It is.

  Now, as shown in FIG. 8 (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 payout plates 430 and 430 are in a horizontal posture together with the pushers 440 and 440.

  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, one of the pushers 440, 440 of the dispensing plates 430, 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. 8A 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 upper PTP tablet sheet 902 comes into contact with the oblique portion formed at the lower part of the pressing piece 5313x ′ and presses the tip downward, so that the interval with the lower PTP tablet sheet 901 is reduced, and the compressed state Overlay height. The set of PTP tablet sheets 901 and 902 in this compressed state can pass through the partition piece 5313. On the other hand, for the set of PTP tablet sheets 903 and 904, the upper PTP tablet sheet 904 comes into contact with the lower part of the partition piece 5313, and the set of PTP tablet sheets 903 and 904 is prevented from passing through the partition piece 5313.

  Then, the two PTP tablet sheets 901 and 902 that have passed through the partition piece 5313 drop by gravity onto the payout plates 430 and 430 of the take-out unit 400. 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 pushers 440 and 440 and return to the original positions. The pushing member 5515 also returns to the original last part. 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. Hereinafter, it is the same as that of the first embodiment.

As described above, according to the second embodiment, by placing the PTP tablet sheets 901, 902,... In the tablet cassette 500 so as to face each other with the pockets not overlapping each other, PTP tablet sheets 901, 902,... Are stored as a set of two sheets, and PTP tablet sheets 901, 902,. The opening 5318 formed in the front wall 531 of the tablet cassette 500 is partially blocked by the partition piece 5313 so that the tablet cassette 500 is taken out of the tablet cassette 500 in units of multiples of the tablet cassette 500 and from the partition piece 5313 on the upstream side of the partition piece 5313. Also, the pressing piece 5313x ′ capable of closing the side near the bottom surface 5301 of the opening 5318 is rotatable around the mounting member 5313y ′. Only, the push flaked 'because the is the side closer to the bottom surface 5301 lower end of the tilted outward, before through the partition pieces 5313, the pressing piece 5313x' 5313x its own weight (or appended spring-loaded to the ) To press the set of PTP tablet sheets 901 and 902 downward, it is possible to prevent the set of PTP tablet sheets 901 and 902 from being lifted from the bottom plate 5301.

  As a result, not only a set of PTP tablet sheets 901, 902,... Without significant deviation in the front and back, but also a set of PTP tablet sheets 901, 902,. The PTP tablet sheets 901, 902,... Can be sequentially taken out to the outside in units of sets or multiples of the set because the pop-up prevention pieces 543 can be passed over the partition pieces 5313. As a result, the PTP tablet sheets 901, 902, ... can be supplied in a large amount and stably.

  In the first and second embodiments, two cassette shelves 600 and 600 are arranged on the left and right. However, the cassette shelves 600 and 600 may be arranged on the front and back, and one or three or more cassette shelves are arranged. It is good as well. In this case, it is preferable from the viewpoint of work efficiency that the number of carriages, take-out units, etc. correspond to this.

  Further, when two or more cassette shelves are arranged, a part of the PTP tablet sheets may be taken out from the tablet cassette one by one like a conventional dispensing device. In that case, you may make it perform what is called a fraction process which cuts a PTP tablet sheet | seat into the predetermined number of tablets with a cutting unit, and dispenses it.

  In the first and second embodiments, one take-out unit 400 is moved to a plurality of tablet cassettes 500 so that the PTP tablet sheet is dispensed from the tablet cassette 500. Units may be provided in a one-to-one correspondence. In that case, the configuration of the take-out unit can be simplified.

  In the first and second embodiments, each PTP tablet sheet 901, 902,... Is dispensed from the tablet cassette 500 in units of two sets, but may be dispensed in multiples of this set. This makes it possible to dispense the optimal number of PTP tablet sheets 901, 902,... From the tablet cassette 500 according to the content of the prescription, which is convenient.

  .. Instead of extruding the PTP tablet sheets 901, 902... From the tablet cassette 500 in set units or multiple set units thereof, the PTP tablet sheets 901, 902. It is good also as employ | adopting the system pulled out by the set unit of multiple.

  Moreover, in the said Embodiment 1, 2, the PTP tablet sheet | seat 901,902, ... of the horizontal attitude | position was set to the tablet cassette 500 as a set of 2 sheets each, and the one piled up and down was illustrated. However, the scope of application of the present invention is not limited to this, and PTP tablet sheets 901, 902,. May be. In this case, since the spring force works instead of gravity, the same result as described above is obtained.

  In the first and second embodiments, the PTP tablet sheets 901, 902,... Are so-called ear-attached sheets each provided with an ear 930. However, some or all of them are not provided with the ear 930. A so-called earless sheet may be used. Even in that case, since the PTP tablet sheets 901, 902,... Can be packed in the tablet cassette 500 almost without any gap, as in the case of the sheet with ears, the tablet cassette 500 can be downsized. In addition, since the take-out time for each set of PTP tablet sheets 901, 902,... In the take-out unit 400 is substantially constant, the take-out operation is facilitated, and the PTP tablet sheets 901, 902,. Increases speed.

  In the first and second embodiments, the PTP tablet cassettes 500, 500,... Are arranged on the shelf plate 602 of the cassette shelf 600 in the width direction of the PTP tablet cassettes 500, 500,. However, the shelf plate is not limited to a stationary flat plate shape, and may be, for example, a cylindrical shape rotating around a predetermined axis. In that case, it is sufficient to move the take-out unit 400 relative to the PTP tablet cassettes 500, 500,... Mounted on the rotating shelf.
