Description
本発明は、錠剤印刷装置等において、供給される多数の錠剤等の物品を所定の搬送方向に沿って搬送しながら複数列に振り分けるための振分け装置に関するものである。 The present invention relates to a sorting device for sorting a large number of supplied articles such as tablets into a plurality of rows while transporting them along a predetermined transport direction in a tablet printing device or the like.
従来、医療分野において、薬剤師による調剤ミスや患者による誤服用などの医療事故を防止するために、インクジェットプリンタにより錠剤の表面にインクを噴射して印刷を行う錠剤印刷装置が知られている。 Conventionally, in the medical field, in order to prevent medical accidents such as dispensing mistakes by pharmacists and mistaking by patients, tablet printing devices that print by injecting ink onto the surface of tablets by an inkjet printer have been known.
一般に、この錠剤印刷装置は、錠剤が供給される錠剤供給部と、錠剤を搬送する錠剤搬送部と、錠剤の表面に印刷を行う錠剤印刷部と、錠剤の印刷、割れあるいは欠け等の状態を検査する錠剤検査部と、錠剤が排出される錠剤排出部とから構成される。これによると、錠剤に対して非接触で印刷処理を行うことができる。 In general, this tablet printing apparatus has a tablet supply unit to which tablets are supplied, a tablet transport unit for transporting tablets, a tablet printing unit for printing on the surface of tablets, and a state such as tablet printing, cracking or chipping. It is composed of a tablet inspection unit for inspection and a tablet discharge unit for discharging tablets. According to this, the printing process can be performed on the tablets in a non-contact manner.
そして、このような錠剤印刷装置では、錠剤供給部と錠剤搬送部の間に振分け装置が配置される場合が多い。この振分け装置は、各物品を搬送するための搬送溝が搬送方向に延びる態様で複数列設けられたトラフを備え、トラフを搬送方向に振動させることにより、錠剤を所定の搬送方向に沿って搬送しながら複数列に振り分ける（例えば、特許文献１、２参照）。 In such a tablet printing device, a sorting device is often arranged between the tablet supply unit and the tablet transport unit. This sorting device includes troughs provided in a plurality of rows in such a manner that transport grooves for transporting each article extend in the transport direction, and the tablets are transported along a predetermined transport direction by vibrating the troughs in the transport direction. While allocating to a plurality of columns (see, for example, Patent Documents 1 and 2).
しかしながら、通常、錠剤は各搬送溝において一列で搬送されるが、中には各搬送溝において装置の幅方向に２列に並んで搬送されるものがあり、そのような状態で錠剤を錠剤搬送部に受け渡してしまうと、錠剤印刷部により錠剤の表面に印刷を行うことが困難になり、錠剤印刷装置における錠剤印刷の良品率が低下するという問題があった。特に最近では、平面視が円形の錠剤のみならず、平面視が長円形、楕円形、菱形、涙形などのように外形の一辺が直線状の部分を有する異形錠と呼ばれる錠剤が増えてきており、このような異形錠は平面視が円形の錠剤に比べて、幅方向に２列に並んで搬送される場合が多かった。なお、このような問題は、錠剤のみに限られるものではなく、その他の物品にも生じるものであった。 However, normally, the tablets are transported in a single row in each transport groove, but some of them are transported in two rows in the width direction of the device in each transport groove, and the tablets are transported in such a state. If it is delivered to the unit, it becomes difficult for the tablet printing unit to print on the surface of the tablet, and there is a problem that the non-defective rate of tablet printing in the tablet printing apparatus decreases. In particular, recently, not only tablets having a circular plan view but also tablets called deformed tablets having a linear portion on one side of the outer shape such as an oval shape, an ellipse shape, a rhombus shape, and a tear shape in a plan view have increased. Therefore, such a deformed tablet is often transported side by side in two rows in the width direction as compared with a tablet having a circular plan view. It should be noted that such a problem is not limited to tablets, but also occurs in other articles.
本発明は、上述の問題に鑑みてなされたものであって、物品を各搬送溝において一列に簡単かつ確実に振り分けることができる振分け装置を提供することを目的とする。 The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a sorting device capable of easily and surely sorting articles in a row in each transport groove.
本発明は、上記目的を達成するために、物品を所定の搬送方向に沿って搬送しながら複数列に振り分けるための振分け装置であって、各物品を搬送するための搬送溝が搬送方向に延びる態様で複数列設けられ、前記搬送溝は、搬送方向に直交する幅方向に対して一方側に上方に傾斜する第１の溝底面と、幅方向に対して一方側または他方側に上方に傾斜する第２の溝底面とを備える谷形状に形成され、前記第２の溝底面は、幅方向に対する幅方向他方側からの傾斜角度が第１の溝底面の幅方向に対する幅方向一方側からの傾斜角度よりも大きく形成されるとともに、少なくとも搬送方向の一部において、上方から見て搬送方向に対して前記第１の溝底面側に交差する方向に傾斜しながら延びる態様で形成されていることを特徴とする。なお、第１の溝底面および第２の溝底面について、上方に傾斜する状態には直立状態（傾斜角度９０度）も含まれる。 The present invention is a sorting device for sorting articles into a plurality of rows while transporting the articles along a predetermined transport direction in order to achieve the above object, and a transport groove for transporting each article extends in the transport direction. A plurality of rows are provided in the embodiment, and the transport grooves are a first groove bottom surface that is inclined upward on one side with respect to the width direction orthogonal to the transport direction, and the transport grooves are inclined upward on one side or the other side with respect to the width direction. The second groove bottom surface is formed in a valley shape including a second groove bottom surface, and the inclination angle of the second groove bottom surface from the other side in the width direction with respect to the width direction is from one side in the width direction with respect to the width direction of the first groove bottom surface. It is formed to be larger than the inclination angle, and at least in a part of the transport direction, it is formed so as to extend while tilting in a direction intersecting the bottom surface side of the first groove with respect to the transport direction when viewed from above. It is characterized by. The state in which the bottom surface of the first groove and the bottom surface of the second groove are inclined upward includes an upright state (inclination angle of 90 degrees).
これによれば、物品が搬送溝で幅方向に２列に並んで搬送された場合、第２の溝底面側の物品は、第２の溝底面との間において大きな摩擦が生じるため、搬送速度が低下する一方、第１の溝底面側の物品は、幅方向に隣接する第２の溝底面側の物品との間において小さな摩擦しか生じないため、搬送速度がほとんど低下しないことから、第２の溝底面側の物品が第１の溝底面側の錠剤よりも搬送速度が相対的に遅くなる。よって、搬送速度が相対的に速い第１の溝底面側の物品が、搬送速度が相対的に遅い第２の溝底面側の物品よりも搬送方向前方に出る状態となって、物品が当該搬送溝において一列に並びながら搬送されるため、物品を各搬送溝において一列に簡単かつ確実に振り分けることができる。 According to this, when the articles are transported side by side in two rows in the width direction in the transport groove, the articles on the bottom surface side of the second groove generate a large friction with the bottom surface of the second groove, so that the transport speed On the other hand, the article on the bottom surface side of the first groove causes only a small amount of friction with the article on the bottom surface side of the second groove adjacent in the width direction, so that the transport speed hardly decreases. The article on the bottom surface side of the groove has a relatively slower transfer speed than the tablet on the bottom surface side of the first groove. Therefore, the article on the bottom surface side of the first groove having a relatively high transport speed comes out forward in the transport direction with respect to the article on the bottom surface side of the second groove having a relatively slow transport speed, and the article is transported. Since the goods are transported in a row in the grooves, the goods can be easily and surely sorted in a row in each transport groove.
また、前記第２の溝底面は、上方から見て搬送方向に対して傾斜角度が１度〜６０度に形成されているのが好ましい。これによれば、第２の溝底面側の物品は、第２の溝底面との間において適度に大きな摩擦が生じることにより搬送速度が適度に低下するため、物品が当該搬送溝において一列に並びながら搬送され易くなる。 Further, it is preferable that the bottom surface of the second groove is formed at an inclination angle of 1 degree to 60 degrees with respect to the transport direction when viewed from above. According to this, the articles on the bottom surface side of the second groove have a moderately large friction with the bottom surface of the second groove, so that the transport speed is moderately reduced, so that the articles are lined up in a row in the transport groove. However, it becomes easy to be transported.
また、前記第２の溝底面は、幅方向に対して幅方向他方側からの傾斜角度が４５度〜１３５度に形成されているのが好ましい。これによれば、第２の溝底面との間において確実に大きな摩擦が生じることにより搬送速度が確実に低下するため、物品が当該搬送溝において一列に並びながら搬送され易くなる。 Further, it is preferable that the bottom surface of the second groove is formed so that the inclination angle from the other side in the width direction with respect to the width direction is 45 degrees to 135 degrees. According to this, since a large friction is surely generated with the bottom surface of the second groove and the transport speed is surely lowered, it becomes easy to transport the articles while arranging them in a line in the transport groove.
また、前記第２の溝底面は、上方から見て搬送方向に対して前記第１の溝底面側に交差する方向に傾斜しながら延びる部分の搬送方向下流側の端部から、上方から見て搬送方向に対して前記第１の溝底面と反対側に交差する方向に傾斜しながら延びる態様で形成されていてもよい。これによれば、第２の溝底面側の物品が、第２の溝底面との間の摩擦から解放されて早い速度で搬送されるため、搬送方向に隣り合う第２の溝底面側の物品の間に大きな隙間が生じる。このため、第１の溝底面側の物品が、第２の溝底面側の物品の間に生じた当該隙間に入りんだ状態となって、物品が当該搬送溝において一列に並びながら搬送されるため、物品を各搬送溝において一列により一層確実に振り分けることができる。
また、前記第２の溝底面は、第１の溝底面よりも摩擦係数が大きくなるように形成されてもよい。これによれば、第２の溝底面の物品は、第２の溝底面との間においてより大きな摩擦が生じるため、物品が当該搬送溝３１０において一列に並びながら搬送され易くなる。
Further, the bottom surface of the second groove is viewed from above from the end portion on the downstream side in the transport direction of the portion extending while being inclined in a direction intersecting the bottom surface side of the first groove with respect to the transport direction when viewed from above. It may be formed so as to extend while inclining in a direction intersecting the bottom surface of the first groove with respect to the transport direction. According to this, the article on the bottom surface side of the second groove is released from the friction with the bottom surface of the second groove and is conveyed at a high speed, so that the article on the bottom surface side of the second groove adjacent to each other in the conveying direction is conveyed. A large gap is created between the two. Therefore, the articles on the bottom surface side of the first groove are in a state of being inserted into the gap generated between the articles on the bottom surface side of the second groove, and the articles are transported in a line in the transport groove. Therefore, the goods can be more reliably sorted in a row in each transport groove.
Further, the bottom surface of the second groove may be formed so that the friction coefficient is larger than that of the bottom surface of the first groove. According to this, the articles on the bottom surface of the second groove generate a larger friction with the bottom surface of the second groove, so that the articles can be easily transported while being lined up in the transport groove 310.
また、本発明は、上記振分け装置が設けられていることを特徴とする錠剤印刷装置である。 Further, the present invention is a tablet printing device characterized in that the sorting device is provided.
本発明によれば、物品が搬送溝で幅方向に２列に並んで搬送された場合、第２の溝底面側の物品は、第２の溝底面との間において大きな摩擦が生じるため、搬送速度が低下する一方、第１の溝底面側の物品は、幅方向に隣接する第２の溝底面側の物品との間において小さな摩擦しか生じないため、搬送速度がほとんど低下しないことから、第２の溝底面側の物品が第１の溝底面側の錠剤よりも搬送速度が相対的に遅くなる。よって、搬送速度が相対的に速い第１の溝底面側の物品が、搬送速度が相対的に遅い第２の溝底面側の物品よりも搬送方向前方に出る状態となって、物品が当該搬送溝において一列に並びながら搬送されるため、物品を各搬送溝において一列に簡単かつ確実に振り分けることができる。 According to the present invention, when the articles are conveyed in two rows in the width direction in the conveying groove, the articles on the bottom surface side of the second groove cause a large friction with the bottom surface of the second groove, so that the articles are conveyed. While the speed is reduced, the article on the bottom surface side of the first groove causes only a small amount of friction with the article on the bottom surface side of the second groove adjacent in the width direction, so that the transport speed is hardly reduced. The article on the bottom surface side of the groove 2 has a relatively slower transfer speed than the tablet on the bottom surface side of the first groove. Therefore, the article on the bottom surface side of the first groove having a relatively high transport speed comes out forward in the transport direction with respect to the article on the bottom surface side of the second groove having a relatively slow transport speed, and the article is transported. Since the goods are transported in a row in the grooves, the goods can be easily and surely sorted in a row in each transport groove.
このため、例えば本装置を錠剤印刷装置に適用した場合、錠剤供給部に供給された錠剤を錠剤搬送部に対して一列で順次受け渡すため、錠剤印刷部により錠剤の表面に所定の印刷を確実に行うことができ、ひいては錠剤印刷の良品率を向上させることが可能となる。 Therefore, for example, when this device is applied to a tablet printing device, the tablets supplied to the tablet supply section are sequentially delivered to the tablet transport section in a row, so that the tablet printing section ensures that a predetermined print is performed on the tablet surface. As a result, it is possible to improve the non-defective rate of tablet printing.
次に、本発明に係る振分け装置３を錠剤印刷装置１に適用した実施形態について図１〜図８を参照しつつ説明する。 Next, an embodiment in which the sorting device 3 according to the present invention is applied to the tablet printing device 1 will be described with reference to FIGS. 1 to 8.
なお、本実施形態では、装置の長さ方向（図２の左右方向）を搬送方向Ｘとし、該搬送方向Ｘに直交する方向（図２の上下方向）を装置の幅方向として説明する。また、物品として、図８に示すように、一対の表面Ｔ１と周面Ｔ２を有する平面視が長円形の錠剤Ｔを対象として説明する。 In the present embodiment, the length direction of the device (horizontal direction in FIG. 2) is defined as the transport direction X, and the direction orthogonal to the transport direction X (vertical direction in FIG. 2) is described as the width direction of the device. Further, as an article, as shown in FIG. 8, a tablet T having a pair of surfaces T1 and a peripheral surface T2 and having an oval shape in a plan view will be described.
この錠剤印刷装置１は、多数の錠剤Ｔを貯留するホッパー２と、ホッパー２からフィーダ２０を介して供給される多数の錠剤Ｔを複数列に振り分ける振分け装置３と、振分け装置３により複数列に振り分けられた錠剤Ｔを搬送する搬送コンベア４とを備える。 The tablet printing device 1 includes a hopper 2 for storing a large number of tablets T, a sorting device 3 for distributing a large number of tablets T supplied from the hopper 2 via a feeder 20 into a plurality of rows, and a sorting device 3 for a plurality of rows. A transport conveyor 4 for transporting the sorted tablets T is provided.
前記フィーダ２０は、バイブレータ２０ａを有しており、バイブレータ２０ａが搬送方向Ｘに振動することにより錠剤Ｔを振分け装置３側に搬送する。また、前記振分け装置３は、斜め下方に傾斜して配設され、同様にバイブレータ３３を有しており、バイブレータ３３が搬送方向Ｘに振動することにより錠剤Ｔを搬送コンベア４側に搬送する。また、前記搬送コンベア４は、上流側がタイミングプーリ４０に巻き掛けられるとともに、下流側も図示略のタイミングプーリに巻き掛けられ、所定の方向に回転することにより錠剤Ｔを搬送する。 The feeder 20 has a vibrator 20a, and the tablet T is conveyed to the sorting device 3 side by vibrating the vibrator 20a in the conveying direction X. Further, the sorting device 3 is arranged so as to be inclined diagonally downward, and also has a vibrator 33, and the tablet T is transported to the transport conveyor 4 side by vibrating the vibrator 33 in the transport direction X. Further, in the transport conveyor 4, the upstream side is wound around the timing pulley 40, and the downstream side is also wound around the timing pulley (not shown), and the tablet T is conveyed by rotating in a predetermined direction.
前記振分け装置３は、図１に示すように、搬送方向Ｘの上流側に配設された振分けトラフ３１と、搬送方向Ｘの下流側に配設された整列トラフ３２とを備える。 As shown in FIG. 1, the sorting device 3 includes a sorting trough 31 arranged on the upstream side of the transport direction X and an aligned trough 32 arranged on the downstream side of the transport direction X.
前記振分けトラフ３１は、図２に示すように、錠剤Ｔを搬送するための搬送溝３１０が搬送方向Ｘに延びる態様で設けられている。これら搬送溝３１０は、幅方向に７列設けられており、幅方向の左側（図２の上側）の３列の各搬送溝３１０（３１０Ｌ）と、幅方向の右側（図２の下側）の４列の各搬送溝３１０（３１０Ｒ）から構成される。なお、振分けトラフ３１は、上流側に平坦面３１１が形成されており、該平坦面３１１が前記搬送溝３１０の上流側端部に連続して接続されている。 As shown in FIG. 2, the distribution trough 31 is provided with a transport groove 310 for transporting the tablet T extending in the transport direction X. The transport grooves 310 are provided in seven rows in the width direction, and each of the three rows of transport grooves 310 (310L) on the left side (upper side in FIG. 2) in the width direction and the right side (lower side in FIG. 2) in the width direction. It is composed of each of the four rows of transport grooves 310 (310R). The distribution trough 31 has a flat surface 311 formed on the upstream side, and the flat surface 311 is continuously connected to the upstream end portion of the transport groove 310.
前記左側の各搬送溝３１０（３１０Ｌ）は、図４に示すように、幅方向の右側に上方に傾斜する第１の溝底面３１０ａと、幅方向の左側に上方に傾斜する第２の溝底面３１０ｂとを備える谷形状に形成されている。一方、右側の各搬送溝３１０（３１０Ｒ）は、図４に示すように、幅方向の左側に上方に傾斜する第１の溝底面３１０ａと、幅方向の右側に上方に傾斜する第２の溝底面３１０ｂとを備える谷形状に形成されている。 As shown in FIG. 4, each of the transport grooves 310 (310L) on the left side has a first groove bottom surface 310a that inclines upward to the right in the width direction and a second groove bottom surface that inclines upward to the left in the width direction. It is formed in a valley shape including 310b. On the other hand, as shown in FIG. 4, each transport groove 310 (310R) on the right side has a first groove bottom surface 310a that inclines upward to the left in the width direction and a second groove that inclines upward to the right in the width direction. It is formed in a valley shape having a bottom surface 310b.
これら各搬送溝３１０の第１の溝底面３１０ａと第２の溝底面３１０ｂにおける搬送方向Ｘの形態について、振分けトラフ３１の搬送方向Ｘの各Ｂ部〜Ｇ部に分けて具体的に説明する。なお、錠剤Ｔは、長円状に形成されているため、図５に示すように、搬送時において錠剤Ｔの長辺方向（図８（ｂ）の左右方向）が搬送方向Ｘに沿うように搬送されることを前提として説明する。また、図４は、説明の都合上、錠剤Ｔを実際の大きさよりも大きく図示するものとする。 The form of the transport direction X in the first groove bottom surface 310a and the second groove bottom surface 310b of each of the transport grooves 310 will be specifically described separately for each of the B portion to G portion of the transport direction X of the distribution trough 31. Since the tablet T is formed in an oval shape, as shown in FIG. 5, the long side direction (horizontal direction in FIG. 8B) of the tablet T is along the transport direction X during transportation. The description will be made on the assumption that it will be transported. Further, in FIG. 4, for convenience of explanation, the tablet T is shown larger than the actual size.
まず、振分けトラフ３１の上流側のＢ部では、図４（Ｂ）に示すように、第１の溝底面３１０ａは幅方向に対して傾斜角度１０度で形成されるとともに、第２の溝底面３１０ｂは幅方向に対して傾斜角度９０度で形成されている。つまり、平坦面３１１と搬送溝３１０の接続部分Ａ部からＢ部までの間、第１の溝底面３１０ａは幅方向に対して傾斜角度が０度から１０度にかけて次第に大きくなるように形成される一方、第２の溝底面３１０ｂは幅方向に対して傾斜角度が９０度に形成されている。また、第１の溝底面３１０ａおよび第２の溝底面３１０ｂは、図３に示すように、溝底面の上端部から下端部までの高さが次第に高くなっている。また、第１の溝底面３１０ａおよび第２の溝底面３１０ｂは、図２に示すように、いずれも搬送方向Ｘに平行に延びる態様に形成されている。 First, in the portion B on the upstream side of the distribution trough 31, as shown in FIG. 4B, the first groove bottom surface 310a is formed at an inclination angle of 10 degrees with respect to the width direction, and the second groove bottom surface is formed. The 310b is formed at an inclination angle of 90 degrees with respect to the width direction. That is, between the flat surface 311 and the connecting portion A to B of the transport groove 310, the first groove bottom surface 310a is formed so that the inclination angle gradually increases from 0 degrees to 10 degrees with respect to the width direction. On the other hand, the second groove bottom surface 310b is formed at an inclination angle of 90 degrees with respect to the width direction. Further, as shown in FIG. 3, the heights of the first groove bottom surface 310a and the second groove bottom surface 310b from the upper end portion to the lower end portion of the groove bottom surface are gradually increased. Further, as shown in FIG. 2, both the first groove bottom surface 310a and the second groove bottom surface 310b are formed so as to extend in parallel with the transport direction X.
また、振分けトラフ３１の中央部のＣ部では、図４（Ｃ）に示すように、第１の溝底面３１０ａは幅方向に対して傾斜角度３０度で形成されるとともに、第２の溝底面３１０ｂは幅方向に対して傾斜角度９０度で形成されている。つまり、振分けトラフ３１のＢ部からＣ部の間、第１の溝底面３１０ａは幅方向に対して傾斜角度が１０度から３０度にかけて次第に大きくなるように形成される一方、第２の溝底面３１０ｂは幅方向に対して傾斜角度９０度を維持するように形成されている。また、第１の溝底面３１０ａおよび第２の溝底面３１０ｂは、図３に示すように、溝底面の上端部から下端部までの高さが次第に高くなっている。また、第１の溝底面３１０ａおよび第２の溝底面３１０ｂは、その高さが振分けトラフ３１のＡ部からＢ部の間の第１の溝底面３１０ａおよび第２の溝底面３１０ｂの高さよりも搬送方向Ｘに大きな勾配に形成されている。また、第１の溝底面３１０ａおよび第２の溝底面３１０ｂは、図２に示すように、いずれも搬送方向Ｘに平行に延びる態様に形成されている。 Further, in the C portion of the central portion of the distribution trough 31, as shown in FIG. 4C, the first groove bottom surface 310a is formed at an inclination angle of 30 degrees with respect to the width direction, and the second groove bottom surface is formed. The 310b is formed at an inclination angle of 90 degrees with respect to the width direction. That is, between the B portion and the C portion of the distribution trough 31, the first groove bottom surface 310a is formed so that the inclination angle gradually increases from 10 degrees to 30 degrees with respect to the width direction, while the second groove bottom surface is formed. The 310b is formed so as to maintain an inclination angle of 90 degrees with respect to the width direction. Further, as shown in FIG. 3, the heights of the first groove bottom surface 310a and the second groove bottom surface 310b from the upper end portion to the lower end portion of the groove bottom surface are gradually increased. Further, the height of the first groove bottom surface 310a and the second groove bottom surface 310b is higher than the height of the first groove bottom surface 310a and the second groove bottom surface 310b between the A portion and the B portion of the distribution trough 31. It is formed with a large gradient in the transport direction X. Further, as shown in FIG. 2, both the first groove bottom surface 310a and the second groove bottom surface 310b are formed so as to extend in parallel with the transport direction X.
また、振分けトラフ３１の下流側のＤ部では、図４（Ｄ）に示すように、第１の溝底面３１０ａは幅方向に対して傾斜角度３０度で形成されるとともに、第２の溝底面３１０ｂは幅方向に対して傾斜角度９０度で形成されている。つまり、振分けトラフ３１のＣ部からＤ部の間、第１の溝底面３１０ａは幅方向に対して傾斜角度３０度を維持するように形成されるとともに、第２の溝底面３１０ｂは幅方向に対して傾斜角度９０度を維持するように形成されている。また、第１の溝底面３１０ａおよび第２の溝底面３１０ｂは、図３に示すように、溝底面の上端部から下端部までの高さが一定である。 Further, in the D portion on the downstream side of the distribution trough 31, as shown in FIG. 4D, the first groove bottom surface 310a is formed at an inclination angle of 30 degrees with respect to the width direction, and the second groove bottom surface is formed. The 310b is formed at an inclination angle of 90 degrees with respect to the width direction. That is, between the C portion and the D portion of the distribution trough 31, the first groove bottom surface 310a is formed so as to maintain an inclination angle of 30 degrees with respect to the width direction, and the second groove bottom surface 310b is formed in the width direction. On the other hand, it is formed so as to maintain an inclination angle of 90 degrees. Further, as shown in FIG. 3, the heights of the first groove bottom surface 310a and the second groove bottom surface 310b from the upper end to the lower end of the groove bottom surface are constant.
また、振分けトラフ３１のＣ部からＤ部の間、図２および図５に示すように、幅方向の左側の１列目から３列目の搬送溝３１０Ｌにおける第２の溝底面３１０ｂは、上方から見て搬送方向Ｘに対して第１の溝底面３１０ａ側（幅方向の右側）に交差する方向に傾斜角度α（本実施形態では３度）で傾斜しながら延びる態様で形成されている。一方、幅方向の右側の１列目から４列目の搬送溝３１０Ｒにおける第２の溝底面３１０ｂは、上方から見て搬送方向Ｘに対して第１の溝底面３１０ａ側（幅方向の左側）に交差する方向に傾斜角度α（本実施形態では３度）で傾斜しながら延びる態様で形成されている。 Further, as shown in FIGS. 2 and 5, between the C portion and the D portion of the distribution trough 31, the second groove bottom surface 310b in the transport grooves 310L in the first to third rows on the left side in the width direction is upward. It is formed so as to extend while tilting at an inclination angle α (3 degrees in the present embodiment) in a direction intersecting the first groove bottom surface 310a side (right side in the width direction) with respect to the transport direction X. On the other hand, the second groove bottom surface 310b in the first to fourth rows of transport grooves 310R on the right side in the width direction is on the first groove bottom surface 310a side (left side in the width direction) with respect to the transport direction X when viewed from above. It is formed so as to extend while tilting at an inclination angle α (3 degrees in the present embodiment) in a direction intersecting with.
このように前記第２の溝底面３１０ｂは、上方から見て搬送方向に対して第１の溝底面３１０ａ側に交差する方向に傾斜しながら延びる態様で形成されるため、図７に示すように、錠剤Ｔが搬送溝３１０で幅方向に２列に並んで搬送された場合、図５に示すように、第２の溝底面３１０ｂ側の錠剤Ｔは、第２の溝底面３１０ｂとの間において大きな摩擦が生じるため、搬送速度が低下する一方、第１の溝底面３１０ａ側の錠剤は、幅方向に隣接する第２の溝底面３１０ｂ側の錠剤Ｔとの間において小さな摩擦しか生じないため、搬送速度が低下しないことから、第２の溝底面３１０ｂ側の錠剤Ｔが第１の溝底面３１０ａ側の錠剤Ｔよりも搬送速度が相対的に遅くなる。よって、搬送速度が相対的に速い第１の溝底面３１０ａ側の錠剤Ｔが、搬送速度が相対的に遅い第２の溝底面３１０ｂ側の錠剤Ｔよりも搬送方向前方に出る状態となり、錠剤Ｔが当該搬送溝３１０において一列に並びながら搬送される。 As described above, the second groove bottom surface 310b is formed so as to extend while inclining in a direction intersecting the first groove bottom surface 310a side with respect to the transport direction when viewed from above, as shown in FIG. When the tablets T are transported in two rows in the width direction in the transport groove 310, as shown in FIG. 5, the tablet T on the side of the second groove bottom surface 310b is between the tablet T and the second groove bottom surface 310b. Since a large amount of friction is generated, the transport speed is reduced, while the tablet on the side of the bottom surface 310a of the first groove causes only a small amount of friction with the tablet T on the side of the bottom surface 310b of the second groove adjacent in the width direction. Since the transport speed does not decrease, the transport speed of the tablet T on the bottom surface 310b side of the second groove is relatively slower than that of the tablet T on the bottom surface 310a of the first groove. Therefore, the tablet T on the bottom surface 310a side of the first groove, which has a relatively high transport speed, comes out forward in the transport direction with respect to the tablet T on the bottom surface 310b side of the second groove, which has a relatively slow transport speed. Are transported in a line in the transport groove 310.
また、振分けトラフ３１の下流側のＥ部では、図４（Ｅ）に示すように、第１の溝底面３１０ａは幅方向に対して傾斜角度３０度で形成されるとともに、第２の溝底面３１０ｂは幅方向に対して傾斜角度６０度で形成されている。つまり、振分けトラフ３１のＤ部からＥ部の間、第１の溝底面３１０ａは幅方向に対して傾斜角度３０度を維持するように形成される一方、第２の溝底面３１０ｂは幅方向に対して傾斜角度が９０度から６０度にかけて次第に小さくなるように形成されている。また、第１の溝底面３１０ａおよび第２の溝底面３１０ｂは、図３に示すように、溝底面の上端部から下端部までの高さが次第に低くなっている。 Further, in the E portion on the downstream side of the distribution trough 31, as shown in FIG. 4 (E), the first groove bottom surface 310a is formed at an inclination angle of 30 degrees with respect to the width direction, and the second groove bottom surface is formed. The 310b is formed at an inclination angle of 60 degrees with respect to the width direction. That is, between the D portion and the E portion of the distribution trough 31, the first groove bottom surface 310a is formed so as to maintain an inclination angle of 30 degrees with respect to the width direction, while the second groove bottom surface 310b is formed in the width direction. On the other hand, the inclination angle is formed so as to gradually decrease from 90 degrees to 60 degrees. Further, as shown in FIG. 3, the heights of the first groove bottom surface 310a and the second groove bottom surface 310b from the upper end portion to the lower end portion of the groove bottom surface are gradually lowered.
また、振分けトラフ３１のＤ部からＥ部の間、幅方向の左側の１列目から３列目の搬送溝３１０Ｌにおける第２の溝底面３１０ｂは、上方から見て搬送方向Ｘに対して第１の溝底面３１０ａと反対側（幅方向の左側）に交差する方向に傾斜角度２５度で傾斜しながら延びる態様で形成されている。一方、幅方向の右側の１列目から４列目の搬送溝３１０Ｒにおける第２の溝底面３１０ｂは、上方から見て搬送方向Ｘに対して第１の溝底面３１０ａと反対側（幅方向の右側）に交差する方向に傾斜角度２５度で傾斜しながら延びる態様で形成されている。 Further, the second groove bottom surface 310b in the first to third rows of transport grooves 310L on the left side in the width direction between the D portion and the E portion of the distribution trough 31 is the second groove bottom surface 310b with respect to the transport direction X when viewed from above. It is formed so as to extend while tilting at an inclination angle of 25 degrees in a direction intersecting the groove bottom surface 310a of No. 1 (left side in the width direction). On the other hand, the second groove bottom surface 310b in the first to fourth rows of transport grooves 310R on the right side in the width direction is opposite to the first groove bottom surface 310a in the transport direction X when viewed from above (in the width direction). It is formed so as to extend while tilting at an inclination angle of 25 degrees in the direction intersecting the right side).
また、振分けトラフ３１の下流側のＦ部では、図４（Ｆ）に示すように、第１の溝底面３１０ａは傾斜角度３０度で形成されるとともに、第２の溝底面３１０ｂは傾斜角度３０度で形成されている。つまり、振分けトラフ３１のＥ部からＦ部の間、第１の溝底面３１０ａは傾斜角度３０度を維持するように形成される一方、第２の溝底面３１０ｂは傾斜角度が６０度から３０度にかけて次第に小さくなるように形成されている。また、第１の溝底面３１０ａおよび第２の溝底面３１０ｂは、図３に示すように、溝底面の上端部から下端部までの高さが次第に低くなっている。 Further, in the F portion on the downstream side of the distribution trough 31, as shown in FIG. 4 (F), the first groove bottom surface 310a is formed at an inclination angle of 30 degrees, and the second groove bottom surface 310b has an inclination angle of 30. It is formed by the degree. That is, between the E portion and the F portion of the distribution trough 31, the first groove bottom surface 310a is formed so as to maintain an inclination angle of 30 degrees, while the second groove bottom surface 310b has an inclination angle of 60 to 30 degrees. It is formed so that it gradually becomes smaller. Further, as shown in FIG. 3, the heights of the first groove bottom surface 310a and the second groove bottom surface 310b from the upper end portion to the lower end portion of the groove bottom surface are gradually lowered.
また、振分けトラフ３１のＥ部からＦ部の間、幅方向の左側の１列目から３列目の搬送溝３１０における第２の溝底面３１０ｂは、上方から見て搬送方向Ｘに対して第１の溝底面３１０ａと反対側（幅方向の左側）に交差する方向に傾斜角度２５度で傾斜しながら延びる態様で形成されている。一方、幅方向の右側の１列目から４列目の搬送溝３１０における第２の溝底面３１０ｂは、上方から見て搬送方向Ｘに対して第１の溝底面３１０ａと反対側（幅方向の右側）に交差する方向に傾斜角度２５度で傾斜しながら延びる態様で形成されている。 Further, the second groove bottom surface 310b in the first to third rows of transport grooves 310 on the left side in the width direction between the E portion and the F portion of the distribution trough 31 is the second groove bottom surface 310b with respect to the transport direction X when viewed from above. It is formed so as to extend while tilting at an inclination angle of 25 degrees in a direction intersecting the groove bottom surface 310a of No. 1 (left side in the width direction). On the other hand, the second groove bottom surface 310b in the first to fourth rows of transport grooves 310 on the right side in the width direction is opposite to the first groove bottom surface 310a with respect to the transport direction X when viewed from above (in the width direction). It is formed so as to extend while tilting at an inclination angle of 25 degrees in the direction intersecting the right side).
このように、振分けトラフ３１のＤ〜Ｆ部において、前記第２の溝底面３１０ｂは、傾斜角度が搬送方向Ｘの上流側において第１の溝底面３１０ａの傾斜角度よりも大きく形成され、搬送方向Ｘの下流側に向かうにつれて次第に小さくなるように形成されている。このため、仮に錠剤Ｔが起立状態で供給された場合でも、振分けトラフ３１のＤ〜Ｆ部において、第１の溝底面３１０ａから第２の溝底面３１０ｂに向けて起立状態から横倒状態に次第に移行しながら搬送される。 As described above, in the D to F portions of the distribution trough 31, the second groove bottom surface 310b is formed so that the inclination angle is larger than the inclination angle of the first groove bottom surface 310a on the upstream side of the transportation direction X, and the transportation direction. It is formed so that it gradually becomes smaller toward the downstream side of X. Therefore, even if the tablet T is supplied in the upright state, the tablets T gradually change from the upright state to the sideways state from the first groove bottom surface 310a toward the second groove bottom surface 310b in the D to F portions of the distribution trough 31. It is transported while shifting.
また、前記第２の溝底面３１０ｂは、上方から見て搬送方向に対して前記第１の溝底面３１０ａ側に交差する方向に傾斜しながら延びる部分（Ｃ部〜Ｄ部）の搬送方向下流側の端部（Ｃ部）から、上方から見て搬送方向に対して前記第１の溝底面３１０ａと反対側に交差する方向に傾斜しながら延びる態様で形成されている。このため、錠剤Ｔが搬送溝３１０で幅方向に２列に並んで搬送され、振分けトラフ３１のＣ部〜Ｄ部においても２列に並んだ状態が解消されなかった錠剤Ｔが少数ながら存在していた場合、図６に示すように、第２の溝底面側の物品Ｔａ、Ｔｂが、第２の溝底面３１０ｂとの間の摩擦から解放されて早い速度で搬送されるため、搬送方向に隣り合う第２の溝底面３１０ｂ側の錠剤Ｔａ、Ｔｂの間に大きな隙間が生じる。このため、第１の溝底面３１０ａ側の錠剤Ｔｃが、第２の溝底面３１０ｂ側の錠剤Ｔａ、Ｔｂの間に生じた当該隙間に入りんだ状態となって、状態Ｔａ、Ｔｂ、Ｔｃが当該搬送溝３１０において一列に並びながら搬送されるため、錠剤Ｔを各搬送溝３１０において一列により一層確実に振り分けることができる。 Further, the second groove bottom surface 310b is a portion (C portion to D portion) downstream of the transport direction, which extends while being inclined in a direction intersecting the first groove bottom surface 310a side with respect to the transport direction when viewed from above. It is formed so as to extend from the end portion (C portion) of the above portion while being inclined in a direction intersecting the first groove bottom surface 310a with respect to the transport direction when viewed from above. Therefore, the tablets T are transported in two rows in the width direction in the transport groove 310, and there are a small number of tablets T in which the state of being lined up in two rows is not resolved even in the C portion to the D portion of the distribution trough 31. If so, as shown in FIG. 6, the articles Ta and Tb on the bottom surface side of the second groove are released from the friction with the bottom surface 310b of the second groove and are transported at a high speed, so that they are transported in the transport direction. A large gap is formed between the tablets Ta and Tb on the side of the bottom surface 310b of the second groove adjacent to each other. Therefore, the tablet Tc on the bottom surface 310a side of the first groove is in a state of entering the gap formed between the tablets Ta and Tb on the bottom surface 310b of the second groove, and the states Ta, Tb and Tc are changed. Since the tablets T are transported in a row in the transport grooves 310, the tablets T can be more reliably distributed in a row in each transport groove 310.
また、振分けトラフ３１の最下流側のＦ部〜Ｇ部（Ｆ部を除く）の間では、図４（Ｇ）に示すように、第１の溝底面３１０ａは幅方向に対して傾斜角度３０度の一定角度で形成されるとともに、第２の溝底面３１０ｂは幅方向に対して傾斜角度３０度の一定角度で形成され、両側に直立状態の壁部３１０ｃが形成されている。また、振分けトラフ３１のＦ部からＧ部の間における第１の溝底面３１０ａおよび第２の溝底面３１０ｂは、図３に示すように、溝底面の上端部から下端部までの高さは一定であるが、壁部３１０ｃは、高さが次第に高くなっている。 Further, as shown in FIG. 4 (G), between the F portion and the G portion (excluding the F portion) on the most downstream side of the distribution trough 31, the first groove bottom surface 310a has an inclination angle of 30 with respect to the width direction. The second groove bottom surface 310b is formed at a constant angle of degree, and the second groove bottom surface 310b is formed at a constant angle of inclination of 30 degrees with respect to the width direction, and upright wall portions 310c are formed on both sides. Further, as shown in FIG. 3, the height of the first groove bottom surface 310a and the second groove bottom surface 310b between the F portion and the G portion of the distribution trough 31 is constant from the upper end portion to the lower end portion of the groove bottom surface. However, the height of the wall portion 310c is gradually increasing.
また、幅方向の左側の１列目から３列目の搬送溝３１０における壁部３１０ｃは、上方から見て搬送方向Ｘに対して幅方向の右側に交差する方向に傾斜しながら延びる態様で形成されている。一方、幅方向の右側の１列目から４列目の搬送溝３１０における壁部３１０ｃは、上方から見て搬送方向Ｘに対して幅方向の左側に交差する方向に傾斜しながら延びる態様で形成されている。これにより錠剤Ｔは次第に幅方向中央部に向けて互いの距離を縮めながら搬送されていき、整列トラフ３２の搬送溝に受け渡される。 Further, the wall portion 310c in the transport grooves 310 in the first to third rows on the left side in the width direction is formed so as to extend while inclining in a direction intersecting the right side in the width direction with respect to the transport direction X when viewed from above. Has been done. On the other hand, the wall portion 310c in the transport grooves 310 in the first to fourth rows on the right side in the width direction is formed so as to extend while inclining in a direction intersecting the left side in the width direction with respect to the transport direction X when viewed from above. Has been done. As a result, the tablets T are gradually conveyed toward the central portion in the width direction while reducing the distance from each other, and are delivered to the conveying groove of the alignment trough 32.
次に、錠剤Ｔの搬送される過程について説明する。なお、実際には多数の錠剤Ｔが搬送されるが、説明の便宜上、一の錠剤Ｔが幅方向の左側の２列目の搬送溝３１０に搬送される場合について説明する。 Next, the process of transporting the tablet T will be described. Although a large number of tablets T are actually transported, for convenience of explanation, a case where one tablet T is transported to the transport groove 310 in the second row on the left side in the width direction will be described.
まず、錠剤Ｔが水平な横倒状態で供給された場合、図４（Ａ）に示すように、錠剤Ｔは、振分けトラフ３１の平坦面３１１において水平な横倒状態で搬送されたあと、図４（Ｂ）に示すように、振分けトラフ３１のＡ部〜Ｂ部の間において、一方の表面Ｔ１が第１の溝底面３１０ａに支承され、かつ周面Ｔ２が第２の溝底面３１０ｂに支承された傾斜角度０度〜１０度の横倒状態で搬送される。 First, when the tablet T is supplied in a horizontal sideways state, as shown in FIG. 4A, the tablet T is conveyed in a horizontal sideways state on the flat surface 311 of the distribution trough 31, and then in the drawing. As shown in 4 (B), between the A portion and the B portion of the distribution trough 31, one surface T1 is supported by the first groove bottom surface 310a, and the peripheral surface T2 is supported by the second groove bottom surface 310b. It is transported in a sideways state with an inclination angle of 0 to 10 degrees.
そして、振分けトラフ３１のＢ部〜Ｃ部において、図４（Ｂ）〜図４（Ｃ）に示すように、錠剤Ｔは、一方の表面Ｔ１が第１の溝底面３１０ａに支承され、かつ錠剤Ｔの周面Ｔ２が第２の溝底面３１０ｂに支承された傾斜角度１０度〜３０度の横倒状態で搬送される。 Then, in the parts B to C of the distribution trough 31, as shown in FIGS. 4 (B) to 4 (C), the tablet T has one surface T1 supported on the bottom surface 310a of the first groove and the tablet. The peripheral surface T2 of T is conveyed in a laterally laid state with an inclination angle of 10 to 30 degrees supported by the second groove bottom surface 310b.
そして、振分けトラフ３１のＣ部〜Ｄ部において、図４（Ｃ）〜図４（Ｄ）に示すように、錠剤Ｔは、一方の表面Ｔ１が第１の溝底面３１０ａに支承され、かつ錠剤Ｔの周面Ｔ２が第２の溝底面３１０ｂに支承された傾斜角度３０度の横倒状態で搬送される。 Then, in the C to D parts of the distribution trough 31, as shown in FIGS. 4 (C) to 4 (D), the tablet T has one surface T1 supported on the first groove bottom surface 310a and the tablet. The peripheral surface T2 of T is conveyed in a laterally laid state with an inclination angle of 30 degrees supported by the second groove bottom surface 310b.
このとき、図７に示すように、錠剤Ｔが搬送溝３１０で幅方向に２列に並んで搬送された場合、図５に示すように、第２の溝底面３１０ｂ側の錠剤Ｔが第１の溝底面３１０ａ側の錠剤Ｔよりも搬送速度が相対的に遅くなるため、搬送速度が相対的に速い第１の溝底面３１０ａ側の錠剤Ｔが、搬送速度が相対的に遅い第２の溝底面３１０ｂ側の錠剤Ｔよりも搬送方向前方に出る状態となり、錠剤Ｔが当該搬送溝３１０において一列に並びながら搬送される。 At this time, as shown in FIG. 7, when the tablets T are transported side by side in two rows in the width direction in the transport groove 310, as shown in FIG. 5, the tablet T on the bottom surface 310b side of the second groove is the first. Since the transport speed is relatively slower than that of the tablet T on the bottom surface 310a side of the groove, the tablet T on the bottom surface 310a side of the first groove has a relatively high transport speed, and the second groove has a relatively slow transport speed. The tablets T are projected forward in the transport direction from the tablet T on the bottom surface 310b side, and the tablets T are transported in a line in the transport groove 310.
そして、振分けトラフ３１のＤ部〜Ｆ部において、図４（Ｄ）〜図４（Ｆ）に示すように、錠剤Ｔは、一方の表面Ｔ１が第１の溝底面３１０ａに支承され、かつ錠剤Ｔの周面Ｔ２が第２の溝底面３１０ｂに支承された傾斜角度３０度の横倒状態で搬送される。 Then, in the D portion to F portion of the distribution trough 31, as shown in FIGS. 4 (D) to 4 (F), the tablet T has one surface T1 supported on the first groove bottom surface 310a and the tablet. The peripheral surface T2 of T is conveyed in a laterally laid state with an inclination angle of 30 degrees supported by the second groove bottom surface 310b.
このとき、錠剤Ｔが搬送溝３１０で幅方向に２列に並んで搬送され、振分けトラフ３１のＣ部〜Ｄ部においても２列に並んだ状態が解消されなかった錠剤Ｔが少数ながら存在していた場合、図６に示すように、第１の溝底面３１０ａ側の錠剤Ｔｃが、第２の溝底面３１０ｂ側の錠剤Ｔａ、Ｔｂの間に生じた隙間に入りんだ状態となって、状態Ｔａ、Ｔｂ、Ｔｃが当該搬送溝３１０において一列に並びながら搬送される。 At this time, the tablets T were transported in two rows in the width direction in the transport groove 310, and there were a small number of tablets T in the C to D portions of the distribution trough 31 in which the two rows were not resolved. If so, as shown in FIG. 6, the tablet Tc on the bottom surface 310a side of the first groove is in a state of entering the gap formed between the tablets Ta and Tb on the bottom surface 310b side of the second groove. The states Ta, Tb, and Tc are conveyed in a line in the transfer groove 310.
そして、振分けトラフ３１のＦ部〜Ｇ部の間（Ｆ部を除く）において、図４（Ｇ）に示すように、錠剤Ｔは、一方の表面Ｔ１が第１の溝底面３１０ａと第２の溝底面３１０ｂに支承されたほぼ水平の横倒状態で搬送されていき、整列トラフ３２の搬送溝３１０に受け渡される。 Then, between the F portion and the G portion (excluding the F portion) of the distribution trough 31, as shown in FIG. 4 (G), in the tablet T, one surface T1 is a first groove bottom surface 310a and a second groove bottom surface 310a. It is conveyed in a substantially horizontal sideways state supported by the groove bottom surface 310b, and is delivered to the transfer groove 310 of the alignment trough 32.
なお、本実施形態では、錠剤Ｔとして平面視が長円形のものを搬送したが、一対の表面Ｔ１と周面Ｔ２を有する平面視が円形、楕円形、菱形、涙形など、その他の形状のものを搬送してもよい。要は、錠剤Ｔの形状が起立状態と横倒状態の両状態が可能なものであれば、どのような形状の錠剤Ｔを搬送してもよい。 In the present embodiment, a tablet T having an oval shape in a plan view is transported, but a tablet T having a pair of surfaces T1 and a peripheral surface T2 in a plan view having a circular shape, an elliptical shape, a rhombus shape, a teardrop shape, or the like is transported. You may transport things. In short, any shape of the tablet T may be conveyed as long as the shape of the tablet T can be in both an upright state and a lying state.
また、振分けトラフ３１のＣ部〜Ｄ部の間において、第２の溝底面３１０ｂの搬送方向Ｘに対する傾斜角度が３度に形成されるものとしたが、その他の傾斜角度であってもよい。ただ、２列に並んで搬送された錠剤Ｔを確実に１列に移行させるため、第２の溝底面３１０ｂの搬送方向Ｘに対する傾斜角度は１度〜６０度に形成されるのが好ましい。このように第２の溝底面３１０ｂの搬送方向Ｘに対する傾斜角度を１度以上としたのは、第２の溝底面３１０ｂにより錠剤Ｔに対して摩擦を生じさせるためである。また、第２の溝底面３１０ｂの搬送方向Ｘに対する傾斜角度を６０度以下としたのは、第２の溝底面３１０ｂが錠剤Ｔの搬送の障害となることを防止するためである。 Further, although it is assumed that the inclination angle of the second groove bottom surface 310b with respect to the transport direction X is formed at 3 degrees between the C portion and the D portion of the distribution trough 31, other inclination angles may be used. However, in order to ensure that the tablets T transported in two rows are transferred to one row, the inclination angle of the second groove bottom surface 310b with respect to the transport direction X is preferably formed to be 1 degree to 60 degrees. The reason why the inclination angle of the second groove bottom surface 310b with respect to the transport direction X is set to 1 degree or more is that the second groove bottom surface 310b causes friction with respect to the tablet T. Further, the inclination angle of the second groove bottom surface 310b with respect to the transport direction X is set to 60 degrees or less in order to prevent the second groove bottom surface 310b from obstructing the transport of the tablet T.
また、振分けトラフ３１のＣ部〜Ｄ部の間において、第２の溝底面３１０ｂの幅方向に対する傾斜角度を９０度としたが、その他の傾斜角度であってもよい。ただ、２列に並んで搬送された錠剤Ｔを確実に１列に移行させるため、第２の溝底面３１０ｂの幅方向に対する傾斜角度は４５度〜１３５度（すなわち幅方向一方側に４５度以上、幅方向他方側に４５度以上）に形成されるのが好ましい。このように第２の溝底面３１０ｂの幅方向に対する傾斜角度を４５度〜１３５度としたのは、第２の溝底面３１０ｂにより錠剤Ｔに対して摩擦を確実に生じさせるためである。
Further, although the inclination angle of the second groove bottom surface 310b with respect to the width direction is 90 degrees between the C portion and the D portion of the distribution trough 31, other inclination angles may be used. However, in order to ensure transition to a row of tablets T that has been conveyed in two rows, the inclination angle of 45 degrees to 135 degrees with respect to the width direction of the second groove bottom surface 310b (i.e. 4 5 degrees one widthwise side more preferably formed in the other widthwise side 4 or 5 degrees). The reason why the inclination angle of the second groove bottom surface 310b with respect to the width direction is set to 45 degrees to 135 degrees is to ensure that the second groove bottom surface 310b causes friction with respect to the tablet T.
また、振分けトラフ３１のＣ部〜Ｄ部の間において、前記第２の溝底面３１０ｂは、第１の溝底面３１０ａよりも摩擦係数が大きくなるように形成されてもよい。例えば、第２の溝底面３１０ａの表面にゴム素材などの摩擦係数が大きい部材を展着したり、第２の溝底面３１０ａの表面に細かい凹凸を形成することにより表面を粗くすることが挙げられる。これによれば、第２の溝底面３１０ｂ側の錠剤Ｔは、第２の溝底面３１０ｂとの間においてより大きな摩擦が生じるため、錠剤Ｔが当該搬送溝３１０において一列に並びながら搬送され易くなる。 Further, the second groove bottom surface 310b may be formed between the C portion and the D portion of the distribution trough 31 so that the friction coefficient is larger than that of the first groove bottom surface 310a. For example, a member having a large friction coefficient such as a rubber material may be spread on the surface of the second groove bottom surface 310a, or the surface may be roughened by forming fine irregularities on the surface of the second groove bottom surface 310a. .. According to this, since the tablet T on the side of the bottom surface 310b of the second groove causes a larger friction with the bottom surface 310b of the second groove, the tablets T are easily transported while being lined up in the transport groove 310. ..
また、搬送トラフ３１のＤ部〜Ｆ部の間において、第２の溝底面３１０ｂの搬送方向Ｘに対する傾斜角度を２５度としたが、その他の傾斜角度であってもよい。 Further, the inclination angle of the second groove bottom surface 310b with respect to the transfer direction X is set to 25 degrees between the D portion and the F portion of the transport trough 31, but other tilt angles may be used.
また、本発明に係る振分け装置３を錠剤を搬送する機能を有する錠剤印刷装置１に適用した場合について説明したが、その他の物品を搬送する機能を有する装置に適用してもよい。 Further, although the case where the sorting device 3 according to the present invention is applied to the tablet printing device 1 having a function of transporting tablets has been described, it may be applied to other devices having a function of transporting articles.
