Definitions
- the present invention relates to a powder removing device for a tablet dividing feeder when dispensing a tablet by a tablet feeder and dispensing based on a prescription in a hospital, a clinic, a pharmacy, or the like.
- a tablet feeder having a rotor in the plurality of stages around the circumference is provided in the tablet housing case, and selectively from each tablet feeder based on the prescription.
- Dispensing and packaging tablets see FIG. 1 of Patent Document 1 and FIG. 23 of the present application, arranging tablet feeders in a shelf shape, and similarly dispensing tablets selectively from each tablet feeder based on prescriptions (Patent Document 2 FIG. 6). *
- the rotary rotor is stored in a container for storing a large number of tablets, and the rotor is formed with storage grooves (recesses) for storing tablets at equal intervals over the entire circumference of the side surface.
- the tablets in the container are stored in the storage groove and moved in the rotation direction.
- the storage groove faces the discharge port, the tablets in the tablet drop from the storage groove to the discharge port one by one.
- the tablet to be taken at one time is a half tablet (half).
- the tablet is sandwiched by a pair of belt conveyors and moved downward, and the tablet is divided into two by a rotary cutter in the middle of the movement (see FIG. 1 of Patent Document 4).
- the tablet is stopped by a shutter, the tablet is divided into two parts by a cutter, the lower half tablet piece is dropped, and the upper half tablet piece is kept on the cutter. There is one that drops the upper half tablet piece (see FIG. 6 of Patent Document 5).
- JP 2003-63503 A JP 2008-162609 A JP 2005-59903 A JP-A-2-29257 JP-A-11-226089 JP 2006-306430 A JP 2008-200274 A JP 2007-135982 A
- the coating layer is formed by moving the tablet on the cutting blade because the cutting blade is a single blade.
- the coating layer is rolled up and discharged (a) in FIG. 24, or the coating layer is connected to the half tablets T1 and T2.
- the half-tablets T1, T2 remain connected to each other via the feed e and remain on the cutting blade and are not discharged ((b) in the figure), or the half-tablets T1, T2 are discharged while connected.
- 3 is a cutting blade.
- the former tablet dividing machine divides the tablet in the vertical direction, at the same time as the division, the tablet is divided into left and right and falls as two tablet pieces. For this reason, when the tablet piece divided into two is divided by hand, or when the tablet piece to be taken is an odd number, one tablet piece becomes unnecessary and is removed by hand.
- the latter tablet dividing machine can drop the upper and lower tablet pieces individually, if the upper half tablet piece is kept on the cutter, it does not fall and can wait until the next dispensing. That is, there is no inconvenience such as removing one tablet piece as in the former tablet dividing machine. However, since the cutter is moved, the operation is complicated.
- the dust processing in the tablet feeder does not remove (remove) the dust adhered from the tablet, the adhered powder is discharged from the tablet feeder together with the tablet. That is, it does not prevent the adhering dust from entering the tablet packaging bag. It is conceivable to attach the above suction and air blowing means to the tablet passage of the tablet feeder to remove the adhering powder from the tablet, but the suction and spraying mechanism becomes large, and the removed dust Processing is not easy. That is, it is difficult to adopt the means for a tablet feeder to be miniaturized.
- the present invention has a first problem of removing powder (dust) adhering to a tablet with a simple structure, and causes a roll-up state due to the coating material or the like, and cutting and division by the roll-up.
- a second problem is to prevent the tablets (tablet pieces) from being discharged while being connected to each other.
- the present invention provides a powder removing plate having a tablet discharge passage (tablet passage) of a tablet feeder having a hole or a slit having a size that does not allow a tablet to pass through a tablet dropping surface of the passage. It was decided to form. If the tablet falls while rolling on this powder removing plate, the tablet may come off by touching the edge of the hole or slit of the powder removing plate, or it may be peeled off due to the difference in falling speed due to the difference in its own weight. The adhering powder falls through the hole or slit to the lower side of the powder removing plate. That is, the powder adhering to the tablet is removed while passing through the tablet passage. The powder dropped through the powder removing plate is collected by dropping it into a powder collection box or the like provided below the powder removing plate.
- a tablet passage is continuously provided in the discharge port of the tablet feeder that sequentially discharges tablets from the tablet storage case to the discharge port, and the tablet passage has a size that does not allow the tablet to pass therethrough.
- a powder removal plate having a perforation or a slit is interposed across the tablet passage, and the tablet is discharged from the discharge port to reach the powder removal plate, falls on the powder removal plate, and dispenses the tablet passage.
- a configuration leading to the mouth (discharge port) can be employed.
- the powder removal path can be lengthened by providing a plurality of the above-described powder removal plates in a zigzag pattern in the downward direction of the tablet passage.
- the vibration means can be provided on all of them or on a part of them. In some cases, if it is provided at the uppermost stage, the powder removal efficiency is high due to the application of vibration in a state where there is a lot of adhered powder.
- the vibration means a known means such as a vibration motor is employed.
- the vibration means may be provided directly on the powder removing plate or indirectly, for example, on a housing (case) to which the powder removing plate is attached. In short, any position may be used as long as the powder removing plate is vibrated.
- a powder removal plate provided with the vibration means is provided so as to completely block the tablet passage and cross downward, and the tablet passage is opened from the state where the powder removal plate is closed.
- the powder removing plate is provided with moving means for moving from the closed state to the open state and vice versa, the tablet is temporarily placed on the powder removing plate. Since it can stop and give a vibration, the powder removal efficiency can further improve.
- a powder removing plate for closing the tablet passage is configured by arranging a pair of powder removing plates having a porous or slit of a size that does not allow the tablet to pass in an inverted triangle shape.
- the lower end of the powder removing plate has or is in contact with the gap where the tablet does not fall, and at least one of the both powder removing plates is provided with vibration means, and at least one of the both powder removing plates falls between the lower end gaps of the tablets.
- the moving powder removal plate is configured to have a moving means, the tablet can be temporarily stopped on the powder removal plate to give vibration. Therefore, the powder removal efficiency can be further improved.
- the powder removing plate not provided with the vibrating means may be a plate through which tablet powder not having pores or slits does not pass.
- the time for fastening these tablets is set appropriately by taking into consideration the degree to which the adhering powder can be removed by experiments or the like.
- the powder removing plate is rotatably provided at the upper end of the case that forms the tablet passage, and the tablet is dropped by the rotation.
- An allowed configuration can be adopted.
- well-known means such as a solenoid actuator or a motor can be adopted as the means for the rotation.
- a rotating plate whose upper end is in contact with the lower end of the powder removing plate is inclined downward in the opposite direction to the powder removing plate and below the powder removing plate.
- the tablet As the structure of the tablet dividing feeder, the tablet is moved in one direction such as horizontal, a fixed blade is positioned in the middle, and the tablet is cut and divided with the fixed blade by the movement of the tablet.
- the division by the fixed blade the lower tablet piece is discharged, while the upper tablet piece is transferred and held on the support piece continuous to the fixed blade from above the fixed blade, and the upper tablet piece is further moved. Therefore, it is possible to adopt a configuration for discharging from the support piece.
- the fixed blade for cutting is a single blade, for example, as shown in FIG. 24A, the divided tablets T (half tablets T1, T2) always have the fixed blade 3 interposed in the divided state.
- the tablet T Since the upper and lower tablet pieces T1 and T2 are pulled to each other and are raised, the tablet T is fed into the opposite cutting edges and cut from one of the cutting edges. After receiving the action, the cutting action is received by the other cutting edge, or the cutting action is received by the two cutting edges, and the divided tablet further moves through the cutting edge from the point where both cutting edges merge. (See FIG. 20). For this reason, the divided divided tablets T1 and T2 are always divided by a fixed blade, and even if the tablet T is coated on the surface of a sugar-coated tablet or the like, its coating layer is also reliably cut to give rise e. The tablet is surely divided by the fixed blade. The fact that the cutting e is eliminated and the cutting is performed smoothly reduces the generation of cutting powder, helps to achieve the first problem, and achieves the second problem of the present invention.
- This cutting blade As a tablet cutting blade for a tablet splitting feeder that exerts this action, it has a notch that gradually narrows in the direction of relative movement from the edge toward the relatively moving tablet, and the opposite edge of the notch is It is possible to adopt a configuration in which the tips of both the cutting edges become the cutting edges and the tips in the narrowing direction merge and disappear.
- This cutting blade may be a single blade (see the upper blade of reference numeral 33a in FIG. 21), and consists of two overlapping cutting blades, both of which are one of the cutting blades in the overlapping plan view.
- the cutting edge of one of the opposite edges is formed by the cutting edge of the other edge, the cutting edge of the other opposing edge is formed by the cutting edge of the other cutting edge, and the notch is formed between the two cutting edges. (See FIG. 21).
- the powder removing means is provided in the tablet discharge passage, the tablet from which the adhered powder is removed as much as possible is dispensed from the tablet feeder. Further, according to the present invention, since the tablet is divided (cut) with a double-edged cutting blade, the cutting is facilitated, the generation of the cut powder is reduced, and the divided tablet (tablet piece) by the scissors e is reduced. ) Can be reliably prevented.

- the tablet cassette 20 includes a synthetic resin container (tablet storage case) 21 including a rectangular portion 21a, a conical portion 21b, and a bottomed cylindrical portion 21c in this order from the top. It comprises a synthetic resin-made U-shaped support portion 22 in plan view. A large number of tablets T are accommodated in the container 21.
- the upper surface opening of the rectangular portion 21 a can be opened and closed by a lid body 23.
- a synthetic resin rotor 24 is disposed in the cylindrical portion 21c.
- the rotor 24 has a conical upper surface, and pocket portions (storage grooves) 25 extending in the axial direction are formed at a plurality of locations (eight in the embodiment) at equal intervals on the outer peripheral surface.
- the pocket portion 25 has a width capable of holding only one tablet T and has a cross section in a plan view that is a convex arc shape toward the bottom surface (see FIG. 3). Since it is a surface, the tablet T fits snugly into the arc-shaped bottom surface 25 c and stably enters the tablet T in the container 21 so as to overlap one by one as the rotor 24 rotates. For this reason, the first passage 26 through which the tablet T passes is formed between each pocket portion 25 and the inner peripheral surface of the cylindrical portion 21c (see FIG.
- a discharge port 27 is formed in the lower portion of the container 21 (the bottom plate of the cylindrical portion 21c) (see FIG. 5).
- the discharge port 27 has a width that is slightly larger than twice the width of one pocket portion 25 of the rotor 24 (see FIG. 19).
- upper and lower circumferential grooves 24a and 24b into which a partition member 32 and a fixed blade 33 described later enter are formed over the entire circumference (see FIG. 4).
- a tablet dividing mechanism 30 is provided above the discharge port 27 (side surface of the cylindrical portion 21c) of the container 21 of the tablet cassette 20 (see FIGS. 3 and 8). As shown in FIGS. 8 and 9, the tablet dividing mechanism 30 is gripped and fixed to an attachment block 31 in which three flat plate pieces 31 a, 31 b, and 31 c are stacked and two flat plate pieces 31 a and 31 b on the upper side of the block 31.
- a partition member 32 made of a brush, a fixed blade 33 held and fixed to the two lower flat plate pieces 31b and 31c, a fixed blade 33, a lower flat plate piece 31c, a partition member 32, and an intermediate flat plate piece 31b.
- the partition member 32 is positioned between the upper and lower tablets T and T in the pocket portion 25 so as to separate the two T1 and T2. Position adjustment of the fixed blade 33 and the partition member 32 by the spacers 35 and 36 is performed by removing the tablet dividing mechanism 30 (block 31) from the cassette 20.
- the partition member 32 has a bristle shape, enters the upper circumferential groove 24a on the side surface of the rotor 24, enters the pocket portion 25 facing the discharge port 27 as the rotor 24 rotates, and partitions the pocket portion 25 up and down.
- the tablet T at the lowest position in the pocket portion 25 is separated from the tablet T on the upper side (see FIGS. 19A to 19B).
- the fixed blade 33 is moved from the edge (left edge in FIG. 8A) toward the tablet T to the tablet moving direction (right direction in FIG. 8A). And the opposite edges of the notches 34 become arcuate cutting edges 34a and 34b, and the tips of the both cutting edges 34a and 34b are aligned (confluence). And disappeared).
- the leg opening degree (opening angle of the notch 34), the length, and the arc degree of the cutting edges 33a and 33b are appropriately determined in consideration of the movement trajectory and size of the tablet T.
- the fixed blade 33 enters the lower circumferential groove 24b on the side surface of the rotor 24 and cuts the center in the vertical direction of the tablet T in the pocket portion 25 facing the discharge port 27 as the rotor 24 rotates in the horizontal direction (FIG. 19 (a) to (c)).
- the fixed blades (double-blade fixed blades) 33 of the two blade edges 34a and 34b can be configured such that two fixed blades 33a and 33b are stacked. That is, the two cutting blades 33a and 33b are composed of two overlapping cutting blades 33a and 33b, and the two cutting blades 33a and 33b are formed so that the cutting edge 34a of the one opposing edge is formed by the cutting edge of the one cutting blade 33a and the other.
- the cutting edge 33b of the cutting edge 33b forms the cutting edge 34b of the other opposite edge, and the notch 34 is formed between the cutting edges 34a, 34b.
- the lower guide 37 is brought into contact with the tablet T in the pocket portion 25 about to face the discharge port 27, and is gradually pushed upward as the rotor 24 rotates to press the tablet T against the fixed blade 33.
- the tablet sliding contact surface (upper surface) of the lower guide 37 is inclined upward from the horizontal and becomes horizontal, and the center of the tablet T is inclined from the former horizontal surface to the inclined surface.
- the fixed blade 33 (cutting edge 34a, 34b) bites into (see both FIGS. 19 and 20 (a)), and then the tablet T moves to the fixed blade 33 with the urging force of the lower guide 37 while moving on the latter horizontal plane. While being pressed, the biting allowance of the fixed blade 33 to the tablet T is absorbed by the downward deflection of the lower guide 37 (see FIG. 19A to FIG. 19B).
- the fixed blade 33 bites into the center of the upper and lower sides of the tablet T due to the spring property of the lower guide 37, and the pieces are smoothly divided while minimizing fragments (chip pieces and cutting powder b).
- the fixed blade 33 is always interposed between the upper and lower tablets T1 and T2 before being dropped after cutting (FIGS. 20 (a) to (c))
- the tablet T whose surface is coated with a sugar-coated tablet or the like is used. Even in such a case, the coating layer is also surely cut, so that it is difficult to generate the back-up e. Even if the back-up e is generated, the back-up e is cut at the junction of the two blade edges 34a, 34b. For this reason, as shown in FIG. 24, the state where the feed e is generated or the divided tablets T1, T2 are connected with the feed e is minimized.
- the rotation of the rotor 24 in one direction ensures that the tablet T is divided into two parts and the upper and lower divided tablet pieces T1, T2 are time difference (22.5). It is paid out with a rotation difference of degree). For this reason, prescription including half tablets for each dose for one patient, and 9 half tablets with an odd number of packages (for example, 3 days in the morning, noon, and evening)
- the rotor 24 is stopped in a state where the upper tablet piece T2 is placed on the tip of the fixed blade 33. If it is a prescription, the rotor 24 will be stopped when the upper tablet piece T2 is paid out from the front-end

Abstract
Description
この錠剤分割機として、対のベルトコンベアによって錠剤を挟んで下側に移動させるとともに、その移動途中で回転カッターによって錠剤を2分割したり(特許文献4第1図参照)、チューブ内に錠剤を移動させ、その途中において、シャッターにより錠剤を止め、カッターによりその錠剤を2分割して、下半分の錠剤片を落下させるとともに、上半分の錠剤片はカッター上に留め置き、カッターの退去によって、その上半分の錠剤片を落下させたりするものがある(特許文献5第6図参照)。
このため、上記錠剤フィーダのロータからの払い出し通路の途中にブラシでもってその粉塵を掻き集めて排出口から排出する技術がある(特許文献6 請求項3、段落0024、図2参照)。
また、錠剤の製造工程や検査工程においては、錠剤に付着する粉塵を吸引や空気吹付けによって除去する技術がある(特許文献7要約、特許文献8要約参照)。
一部がささくれ状態で残れば、2分割した半錠T1、T2の大きさが異なることとなって、服用量に問題が生じる。また、両錠剤片T1、T2が繋がっていると、その錠剤片を分けて分包する場合、手でもってその繋がりを解消する必要があって面倒である。
なお、このように、ささくれeが生じると、確実に半錠T1、T2に分割された場合に比べて、切断粉等の粉も多くなりがちである。
一方、後者の錠剤分割機は、上下の錠剤片を個別に落下し得るため、カッターの上に上半分の錠剤片を留め置けば、落下することがなく、次の払出まで待つことができる。すなわち、前者の錠剤分割機のような一錠剤片を取り除く等の不都合はない。
しかし、カッターを動かすため、その動作が煩雑となっている。
錠剤フィーダの錠剤通過路に上記吸引や空気吹付けの手段を付設して、錠剤から付着粉を除去することも考えられるが、その吸引・吹付け機構が大掛りになるとともに、除去した粉塵の処理は容易ではない。すなわち、小型化される錠剤フィーダにはその手段は採用しがたい。
この粉除去板上を錠剤が転がりながら落下すると、錠剤が粉除去板の孔又はスリットの縁に触れることによって付着する粉が剥ぎ取られたり、自重の差による落下速度の差によって剥がれたりして、付着粉はその孔又はスリットを通って粉除去板の下方に落下する。すなわち、錠剤に付着する粉は錠剤通路を通る間に除去される。
粉除去板を通って落下した粉はその下方に設けた集粉ボックス等に落下させて集める。
また、上記粉除去板に振動手段を設ければ、その除去効率を増すことができる。その振動手段は、粉除去板が複数ある場合には、その全てに設けたり、その一部に設けたりすることができる。一部の場合、最上段に設ければ、付着粉の多い状態での振動付与のため、その粉除去効率が高いものとなる。振動手段としては、振動モータ等の周知の手段を採用する。また、振動手段は粉除去板に直接に設けても間接的に、例えば、粉除去板を取り付けた筐体(ケース)などに設けても良い。要は、粉除去板を振動させる位置であれば、いずれでも良い。
それらの錠剤を留める時間は、実験などによって、付着粉が除去できる程度を考慮して適宜に設定する。
そのさらに具体的な構成としては、その粉除去板の下端に上端が当接する回動板をその下方への傾斜方向が前記粉除去板の反対方向となってその粉除去板の下方となるように上記ケースに設け、その回動板を上記回転手段でもって回動することによって上記錠剤の落下防止をしたり、錠剤の落下を許容したりする構成を採用することができる。
このとき、上記切断用固定刃が片刃であると、例えば、上記図24(a)に示すように、分割された錠剤T(半錠T1、T2)がその分割状態で必ず固定刃3を介在して通り抜ける状態がないから、上下の錠剤片T1、T2が引張り合ってささくれeが生じるが、この両刃であると、錠剤Tは、その対向する両刃先内に送り込まれて一方の刃先から切断作用を受けた後、他方の刃先によって切断作用を受け、又は両刃先によって切断作用を受け、やがて、その両刃先が合流する点からは分割された錠剤は切断刃を介してさらに移動することとなる(図20参照)。このため、分割された分割錠剤T1、T2は必ず固定刃によって分断されることとなり、糖衣錠等の表面がコーティングされた錠剤Tであっても、そのコーティング層も確実に切断されてささくれeが生じることも極力なくなり、錠剤は固定刃により確実に分割される。このささくれeがなくなって切断が円滑に行われることは切断粉の発生も少なくなって上記第1の課題達成の手助けとなるとともに、この発明の第2の課題を達成する。
この切断刃は、一枚ものでも良いが(図21の符号33aの上側の刃 参照)、2枚の重なり合った切断刃から成り、その両切断刃は前記重なり合った平面視でその一方の切断刃の刃先によって一方の対向縁の刃先が形成され、他方の切断刃の刃先によって他方の対向縁の刃先が形成されて、その両刃先の間に上記切欠きが形成されている構成のものとすることもできる(図21参照)。
また、この発明は、両刃の切断刃でもって錠剤を分割(切断)するようにしたので、その切断が円滑となって、その切断粉の発生が減少するとともに、ささくれeによる分割錠剤(錠剤片)の繋がりを確実に防止できる。
また、装着台11には、図示しない制御装置からの制御信号に基づいて駆動制御されるモータ(図示せず)が収容されている。モータの回転軸は、装着台11の錠剤カセット取付面11aの隅に突出してピニオン13が固着されている。
さらに、装着台11には錠剤カセット20の排出口27に連通(連続)する下側に傾斜した第2通路(錠剤通路)14が形成され、この第2通路14は、その両側面に通過する錠剤(片)T(T1、T2)を検出するためのセンサ18が設けられて、薬剤分包機の上記ホッパーHに通じる錠剤通路に連続している(詳細は、特許文献3段落0047、図1参照)。
なお、第2通路14の途中には、磁気センサを設けて、万一、後述の固定刃33が破損し、その破片が薬剤と一緒に払出された場合にも、その通過する金属破片を検知できるようにしたり、磁石を通路14に設けて積極的に金属破片を付着するようにしたりしてもよい。
ロータ24の外面には、後述の仕切部材32及び固定刃33が入り込む上下の周溝24a、24bが全周に亘って形成されている(図4参照)。
上記スペーサ35、36はその枚数を適宜に設定して、固定刃33がポケット部25内の下ガイド37で上下方向の位置決めがされている錠剤Tの上下方向中央に位置してその錠剤Tを丁度半分(半錠T1、T2)となるようするとともに、仕切部材32がポケット部25内に上下の錠剤T、Tの丁度間に位置して両者T1、T2を分離するようにする。このスペーサ35、36による固定刃33と仕切部材32の位置調整は、錠剤分割機構30(ブロック31)をカセット20から取り外して行う。
この固定刃33はロータ24側面の下側周溝24bに入り込んで、ロータ24の水平方向の回転に伴い上記排出口27に臨んだポケット部25内の錠剤Tの上下方向中央を切断する(図19(a)から(c)参照)。
このロータ24の回転に伴い、錠剤Tは2分割され、下側の錠剤片T1はその2分割とともに排出口27に落下し(図19(c))、上側の錠剤片T2は、さらなるロータ24の回転によって支持片を兼ねる固定刃33先端部から排出口27に落下する(同図(d))
このとき、下ガイド37のバネ性でもって、錠剤Tの上下中央に固定刃33が食い込み、破片(欠片や切断粉b)を最小限に抑えて円滑に分割される。
また、切断後の落下する前の上下の錠剤T1、T2の間には必ず固定刃33が介在するため(図20(a)~(c))、糖衣錠等の表面がコーティングされた錠剤Tであっても、そのコーティング層も確実に切断されてささくれeは生じにくく、仮に、ささくれeが生じていても、両刃先34a,34bの合流点においてそのささくれeは切断される。このため、図24で示す、ささくれeが生じたり、ささくれeでもって分割錠剤T1、T2が繋がったりする状態は極力なくなる。
上記接点46、47の数を適宜に設定することによって設定し得る錠剤Tの大きさ等(タイミング)の数も任意に設定できる。 因みに、通常、カセット20の収納錠剤Tが同じの場合は(スイッチ48の設定が同一の場合)、カセット20を外して再セットしても、今までの錠剤計数や錠剤有無の記録はリセットされず、スイッチ48の設定が異なれば、カセット20の再セット時にはそれらの記録はリセットされる。
上記錠剤通路14の上部は四角筒状部材92で構成され、この四角筒状部材92の内側面に上記センサ18を突出させる孔92aを有し、その内下面は下方に開口しない傾斜スリット板93となっており、錠剤分割フィーダA1の排出口27から排出された(払い出された)錠剤T1、T2がこのスリット板93上に落下し、さらに、その錠剤T1、T2は上記粉除去装置(ケース61)内に落下する。
上記軸67にはバネ68が設けられ、このバネ68によってこの粉除去板64bがその下端が一方の粉除去板64aに向く方向に付勢されており、ストッパ69がケース61内面の当て板69aに当接して、上記他の粉除去板64aの間隙(当接)tが確保される(図12、図15参照)。
このとき、摺動子79の移動量はプランジャー85aのワイヤ83の引込量によって決定される。すなわち、回動板75の揺動量が決定される。案内回転ローラ84にはワイヤ83がずれないように案内溝84aが形成されている。この案内回転ローラ84は回転しないものでも良い。
この揺動によって他方の粉除去板64bも揺動して一方の粉除去板64aとの間隙tが大きくなってその粉除去板64a、64b間の錠剤T1、T2がその間隙tから下方に落下する(間隙tが開いて錠剤の落下を許容する)。一方、プランジャー85aの吸引が解除されると、バネ81によって摺動子79は復帰し、同図実線のように、回動板75と他方の粉除去板64bが揺動して復帰する。
そのロータ24の回転は、払出す錠剤片T1、T2の数に応じた回転角度、例えば、ロータ周囲8個の収納溝25があることから、ロータ24が一回転すると、錠剤片(半錠)T1、T2は16個(錠)払出されるため、14半錠であれば、360度/(14/16)=315度回る。このとき、この実施形態はその払出し数に応じた回転角度までの連続回転するが、半錠の払出し毎の22.5度の間欠回転とすることもできる。
粉除去板64a、64b、66上を落下する錠剤T1、T2はこの機構の払出し口90(カバー91の下側開口)から払出されて、上記ホッパーHに送り込まれて、そのホッパーHから包装工程Eに導かれる。
すなわち、図22に示すように、粉除去板64a、64b、66等を錠剤通路14を横切るように下向き傾斜させて設ける。この実施形態では、四角筒状部材92によって錠剤通路14の上部を構成せず、その背面はカバー板92’で塞いでいる。勿論、四角筒状部材92で構成しても良く、逆に、上記図11a、同bの実施形態においても、この図22で示す錠剤通路14の上部構造とし得る。両実施形態において、各粉除去板は固定でも着脱自在でもよい。
因みに、この発明の粉除去装置は、錠剤フィーダA、A1の排出口27に連続する錠剤通路14に限らず、例えば、その錠剤通路14からホッパーHに通じる錠剤通路やそのホッパーHから包装工程Eへの錠剤通路等のあらゆる錠剤通路に介設して錠剤付着粉bの除去を行うことができる。
