錠剤などの成形品を検査装置に搬送する搬送装置が知られている(特許文献1参照)。この搬送装置は、回転体の基部の外周面に、径方向に沿って内側方に凹み、かつ、外側方に開口するポケットが設けられており、回転体は、ポケットに成形品を吸着して回転軌道に沿って検査装置に搬送する。 2. Description of the Related Art A conveyance device that conveys a molded product such as a tablet to an inspection device is known (see Patent Document 1). In this conveying device, a pocket is provided on the outer peripheral surface of the base of the rotating body, which is recessed inward along the radial direction and opens outward, and the rotating body attracts the molded product to the pocket. It is transported to the inspection device along the rotational trajectory.

検査装置は、成形品の移動の軌跡と平面視で重なり合う位置に設置した光源および受光素子であるセンサを有し、光源とセンサは、成形品と成形品を搬送する回転体を挟んで上下方向に対向している。 The inspection device has a light source and a sensor, which is a light-receiving element, installed at a position that overlaps the locus of movement of the molded product in a plan view. is facing.

以下、図面を参照して、本発明の実施形態に係る物品検査装置の構成について、図1から図7に基づいて説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, with reference to the drawings, the configuration of an article inspection apparatus according to an embodiment of the present invention will be described based on FIGS. 1 to 7.

図1において、一実施形態に係る物品検査装置1は、検査対象の物品を整列して単品搬送させながら所定の物品検査位置で光を照射し、この光の照射に伴って物品を透過した光の分光特性に基づいて物品の品質を検査する。 In FIG. 1, an article inspection device 1 according to an embodiment irradiates light at a predetermined article inspection position while arranging articles to be inspected and transporting them individually, and light transmitted through the articles as a result of the irradiation of the light. Inspect the quality of articles based on their spectral properties.

検査対象である物品は、光の照射領域が検査対象の物品に光を照射する照射口の径に比較的近い小径の物品であり、非包装で単品搬送が可能な外径φ:数mm~数十mmの物品、一口サイズの物品の他、既存の製造設備や検査機能を持たない製造設備で製造された所定形状の物品や成形品、特に搬送過程で形が変化しない物品を含む。 The item to be inspected is a small-diameter item in which the light irradiation area is relatively close to the diameter of the irradiation port that irradiates light onto the item to be inspected, and the outer diameter φ is from several mm to allow for single item transportation without packaging. In addition to articles of several tens of millimeters and bite-sized articles, this includes articles and molded articles of a predetermined shape manufactured by existing manufacturing equipment or manufacturing equipment without inspection functions, especially articles whose shape does not change during the transportation process.

該当する物品としては、例えば錠剤、カプセル剤、トローチ剤、ドロップ剤などの製剤、飴、チョコレートなどがある。以下、検査対象の物品として、平面視で円形とされ、その直径に比して高さ(厚さ)の小さい側面視が略円柱状の錠剤Wを例にとって説明する。本実施形態の錠剤Wは、物品を構成する。 Applicable articles include, for example, preparations such as tablets, capsules, troches, and drops, candies, and chocolates. Hereinafter, as an example of an article to be inspected, a tablet W which is circular in plan view, has a substantially cylindrical shape in side view and has a smaller height (thickness) than its diameter will be described. The tablet W of this embodiment constitutes an article.

図1に示すように、物品検査装置1は、錠剤Wを円周状の搬送コースに沿って搬送する物品搬送装置2と、搬送コースの途中の物品検査位置P5で錠剤Wの検査を行なう物品検査部3とを備えている。 As shown in FIG. 1, the article inspection device 1 includes an article conveyance device 2 that conveys tablets W along a circumferential conveyance course, and an article inspection device 2 that conveys tablets W along a circumferential conveyance course, and an article inspection device that inspects the tablets W at an article inspection position P5 in the middle of the conveyance course. and an inspection section 3.

図1、図2に示すように、物品搬送装置2は、回転する深皿状の供給容器10と、供給容器10の内部に設置され、供給容器10と別の駆動源で回転する円形の内側搬送部11とを有する。 As shown in FIGS. 1 and 2, the article conveyance device 2 includes a rotating deep-dish-shaped supply container 10, and a circular inner surface that is installed inside the supply container 10 and rotates by a drive source separate from the supply container 10. It has a transport section 11.

図2に示すように、供給容器10は、上面が開放され、上面から下方に向かって断面積が漸次小さくなる円形形状に形成されている。供給容器10は、上面の開口部10aに全周にわたって所定幅で設けられた水平な環状のフランジであり、錠剤Wの搬送経路となる外側搬送部12と、一部分に貫通孔13bを有し、外側搬送部12よりも直径が小さい円形の底壁13と、外側搬送部12と底壁13をつなぐ筒状の側壁14とを備えている。 As shown in FIG. 2, the supply container 10 has an open upper surface and is formed into a circular shape whose cross-sectional area gradually decreases downward from the upper surface. The supply container 10 is a horizontal annular flange provided with a predetermined width around the entire circumference at an opening 10a on the upper surface, and has an outer conveyance part 12 that serves as a conveyance path for the tablets W, and a through hole 13b in a part, It includes a circular bottom wall 13 having a smaller diameter than the outer conveyance section 12 and a cylindrical side wall 14 that connects the outer conveyance section 12 and the bottom wall 13.

本実施形態の内側搬送部11は、外側搬送部12の径方向内方に設けられている。換言すれば、外側搬送部12は、物品搬送装置2の上面視で内側搬送部11の周囲を取り囲むように内側搬送部11の径方向外方に設けられている。 The inner conveying section 11 of this embodiment is provided radially inward of the outer conveying section 12. In other words, the outer conveyance section 12 is provided radially outward of the inner conveyance section 11 so as to surround the inner conveyance section 11 when viewed from above of the article conveyance device 2 .

供給容器10は、図示しない本体フレームに回転自在に取付けられている。供給容器10の回転軸は、底壁13の中心を通り、底壁13に垂直な線に一致する。供給容器10の底壁13の下面には、底壁13に中心を一致させて環状の内歯ギア10bが固定されている。 The supply container 10 is rotatably attached to a main body frame (not shown). The axis of rotation of the supply container 10 coincides with a line passing through the center of the bottom wall 13 and perpendicular to the bottom wall 13. An annular internal gear 10b is fixed to the lower surface of the bottom wall 13 of the supply container 10 with its center aligned with the bottom wall 13.

本体フレームには第1のモータ21が取付けられており、第1のモータ21の駆動軸21aに設けられたピニオン22が内歯ギア10bに噛み合っている。第1のモータ21が駆動されると、供給容器10(外側搬送部12)は、その回転中心軸の周りを回転方向A(図1参照)に向けて回転する。本実施形態においては、物品搬送装置2の平面視で供給容器10の回転方向Aは、反時計回転方向である。 A first motor 21 is attached to the main body frame, and a pinion 22 provided on a drive shaft 21a of the first motor 21 meshes with an internal gear 10b. When the first motor 21 is driven, the supply container 10 (outer conveyance section 12) rotates around its rotation center axis in the rotation direction A (see FIG. 1). In this embodiment, the rotation direction A of the supply container 10 in a plan view of the article conveyance device 2 is a counterclockwise rotation direction.

図1、図2に示すように、内側搬送部11は、供給容器10の内部において傾斜して配置されている。内側搬送部11の直径は、供給容器10の底壁13の直径よりも大きいので、内側搬送部11を供給容器10内に傾斜して収容できる。すなわち、供給容器10は、上面が開放され、上面から底壁13に向かって断面積が小さくなる円形形状に形成されているので、内側搬送部11を供給容器10に傾斜して収容できる。 As shown in FIGS. 1 and 2, the inner conveyance section 11 is arranged at an angle inside the supply container 10. As shown in FIGS. Since the diameter of the inner conveying part 11 is larger than the diameter of the bottom wall 13 of the supply container 10, the inner conveying part 11 can be accommodated in the supply container 10 at an angle. That is, since the supply container 10 is formed in a circular shape with an open top surface and a cross-sectional area decreasing from the top surface toward the bottom wall 13, the inner conveyance section 11 can be housed in the supply container 10 at an angle.

図2に示すように、内側搬送部11の傾斜方向の上端部11bは、供給容器10の側壁14の上縁に対峙しており、内側搬送部11の周方向について上端部11bとは180°反対側に位置する傾斜方向の下端部11cは、供給容器10の側壁14の下縁に対峙している。 As shown in FIG. 2, the upper end portion 11b of the inner conveying portion 11 in the inclined direction faces the upper edge of the side wall 14 of the supply container 10, and is 180 degrees from the upper end portion 11b in the circumferential direction of the inner conveying portion 11. The lower end portion 11c in the inclined direction located on the opposite side faces the lower edge of the side wall 14 of the supply container 10.

すなわち、内側搬送部11の傾斜方向の下端部11cは、供給容器10の側壁14の下縁に対峙している部分が最も低く、内側搬送部11の傾斜方向の上端部11bは、供給容器10の側壁14の上縁に対峙している部分が最も高い。内側搬送部11の下面の中央には駆動軸11a(図2参照)が内側搬送部11に対して垂直に固定されており、駆動軸11aは、傾斜した状態で供給容器10の底壁13の貫通孔13bを挿通して第2のモータ23(図2参照)に連結されている。 That is, the lower end portion 11c of the inner conveying portion 11 in the inclined direction is the lowest at the portion facing the lower edge of the side wall 14 of the supply container 10, and the upper end portion 11b of the inner conveying portion 11 in the inclined direction is the lower end portion 11c of the inner conveying portion 11 in the inclined direction. The portion facing the upper edge of the side wall 14 is the highest. A drive shaft 11a (see FIG. 2) is fixed perpendicularly to the inner transport section 11 at the center of the lower surface of the inner transport section 11, and the drive shaft 11a is tilted to the bottom wall 13 of the supply container 10. It is inserted through the through hole 13b and connected to the second motor 23 (see FIG. 2).

第2のモータ23は、供給容器10を支持する本体フレームに取付けられており、第2のモータ23が駆動されると、供給容器10の内部において内側搬送部11は、駆動軸11aの周りを回転方向B(図1参照)に回転する。内側搬送部11の回転方向Bと外側搬送部12の回転方向Aは同一方向である。 The second motor 23 is attached to the main body frame that supports the supply container 10, and when the second motor 23 is driven, the inner conveying section 11 moves around the drive shaft 11a inside the supply container 10. Rotates in rotation direction B (see FIG. 1). The rotation direction B of the inner conveyance section 11 and the rotation direction A of the outer conveyance section 12 are the same direction.

図1に示すように、物品搬送装置2は、物品供給部24を備えており、物品供給部24は、物品搬送装置2の上方に設置されている。物品供給部24は、例えば、既存の製造設備や検査機能を持たない製造設備で製造された成形品の錠剤Wが投入されると、投入された錠剤Wを蓄積するとともに、蓄積された錠剤Wを排出口24aから物品投入位置P1に排出し、物品投入位置P1で内側搬送部11に供給する。 As shown in FIG. 1, the article conveyance device 2 includes an article supply section 24, and the article supply section 24 is installed above the article conveyance device 2. For example, when a tablet W of a molded product manufactured by existing manufacturing equipment or a manufacturing equipment without an inspection function is inputted, the article supply unit 24 accumulates the inputted tablets W, and also stores the accumulated tablets W. is discharged from the discharge port 24a to the article input position P1, and supplied to the inner conveyance section 11 at the article input position P1.

物品供給部24は、投入された錠剤Wを内側搬送部11に搬送するもので、例えば、直進フィーダやコンベアなどから構成されている。 The article supply section 24 conveys the input tablets W to the inner conveyance section 11, and includes, for example, a linear feeder, a conveyor, and the like.

物品供給部24は、内側搬送部11と外側搬送部12が錠剤Wを搬送する能力に合わせて錠剤Wを供給する機能を有している。換言すれば、物品供給部24は、物品搬送装置2が錠剤Wを搬送する能力(例えば単位時間当たりの錠剤Wの搬送数など)に合わせて内側搬送部11に対する錠剤Wの供給量が設定される。 The article supply section 24 has a function of supplying tablets W in accordance with the ability of the inner conveyance section 11 and the outer conveyance section 12 to convey tablets W. In other words, in the article supply section 24, the amount of tablets W supplied to the inner conveyance section 11 is set in accordance with the ability of the article conveyance device 2 to convey tablets W (for example, the number of tablets W conveyed per unit time). Ru.

物品搬送装置2において、物品供給部24から内側搬送部11に錠剤Wを投入しつつ、第1のモータ21と第2のモータ23を同方向に同速度または速度を違えて駆動し、内側搬送部11と供給容器10を、同速度で回転方向Aと回転方向Bにそれぞれ回転させると、物品供給部24の最も低い部分(傾斜方向の下端部11c側)に落下した錠剤Wは、内側搬送部11の回転に伴い、内側搬送部11の最も高い部分(傾斜方向の上端部11b側)まで移動し、外側搬送部12に載る。 In the article conveyance device 2, the first motor 21 and the second motor 23 are driven in the same direction at the same speed or at different speeds while feeding the tablets W from the article supply section 24 into the inner conveyance section 11, and the inner conveyance is carried out by driving the first motor 21 and the second motor 23 in the same direction at the same speed or at different speeds. When the part 11 and the supply container 10 are rotated at the same speed in the rotation direction A and the rotation direction B, the tablets W that have fallen to the lowest part of the article supply part 24 (the lower end part 11c side in the inclined direction) are transported inside. As the section 11 rotates, it moves to the highest part of the inner conveying section 11 (the upper end 11b side in the inclined direction) and is placed on the outer conveying section 12 .

図1、図3に示すように、外側搬送部12には溝部12Aと収容溝12Bが設けられている。図4、図5に示すように、溝部12Aは、外側搬送部12の上面12aから下方に窪んでおり、外側搬送部12の径方向に延在している。本実施形態の収容溝12Bは、収容部を構成する。 As shown in FIGS. 1 and 3, the outer conveyance section 12 is provided with a groove section 12A and a housing groove 12B. As shown in FIGS. 4 and 5, the groove portion 12A is depressed downward from the upper surface 12a of the outer conveyance section 12 and extends in the radial direction of the outer conveyance section 12. The housing groove 12B of this embodiment constitutes a housing section.

溝部12Aは、外側搬送部12の周方向に等間隔に複数並んで設けられており、外側搬送部12の周方向にこれら複数の溝部12Aが外側搬送部12の上面12aを挟んで隣接している。 A plurality of groove portions 12A are provided side by side at equal intervals in the circumferential direction of the outer conveyance portion 12, and these groove portions 12A are adjacent to each other in the circumferential direction of the outer conveyance portion 12 with the upper surface 12a of the outer conveyance portion 12 in between. There is.

図3に示すように、溝部12Aは、外側搬送部12の径方向の内端部12nから外端部12mに向かうに従って周方向の幅が漸次狭くなるように形成されている。溝部12Aの内端部12nの周方向の幅は、錠剤Wを周方向に2つに並べたときの幅、すなわち、錠剤Wの直径の2倍の幅よりも小さく(あるいは2つの錠剤Wを周方向に縦向きと横向きにして並べたときの幅よりも小さく)形成されており、錠剤Wが同時に2つ侵入し難い形状に形成されている。 As shown in FIG. 3, the groove portion 12A is formed so that the width in the circumferential direction gradually becomes narrower as it goes from the inner end portion 12n of the outer conveyance portion 12 toward the outer end portion 12m. The width in the circumferential direction of the inner end 12n of the groove 12A is smaller than the width when two tablets W are arranged in the circumferential direction, that is, the width twice the diameter of the tablet W (or the width when two tablets W are arranged in the circumferential direction). The width is smaller than the width when arranged vertically and horizontally in the circumferential direction, and is formed in a shape that makes it difficult for two tablets W to enter at the same time.

具体的には、溝部12Aは、錠剤Wが2つ同時に溝部12Aに侵入しないように形状が設定されている。また、溝部12Aは、錠剤Wが外側搬送部12の上面12aに乗り上げた場合に、上面12aに乗り上げた錠剤Wが溝部12Aに正常な姿勢(横向き)で供給された錠剤Wの高さよりも高さが高くなるように形状が設定されている。 Specifically, the shape of the groove 12A is set so that two tablets W do not enter the groove 12A at the same time. Moreover, when the tablet W rides on the upper surface 12a of the outer conveyance section 12, the groove portion 12A has a height higher than that of the tablet W that has been fed into the groove portion 12A in a normal posture (sideways). The shape is set so that the height is high.

さらに、溝部12Aは、1つの錠剤Wが正常な姿勢(横向き)となり、1つの錠剤Wが姿勢不良(縦向き)になったときに、2つの錠剤Wが同時に溝部12Aに供給されないように、溝部12Aの形状が設定されている。ここで、錠剤W、W1の姿勢が横向きとは、錠剤W、W1の長辺が横方向で短辺が縦方向となった姿勢であり、錠剤W、W1の姿勢が縦向きとは、錠剤W、W1の長辺が縦方向で短辺が横方向となった姿勢であり、錠剤W、W1が縦向きとなった状態では、錠剤W、W1が横向きとなった状態よりも姿勢が高くなる。 Furthermore, the groove 12A is designed to prevent two tablets W from being fed into the groove 12A at the same time when one tablet W has a normal posture (horizontal orientation) and one tablet W has a poor orientation (vertical orientation). The shape of the groove portion 12A is set. Here, the horizontal orientation of the tablets W and W1 means that the long sides of the tablets W and W1 are horizontal and the short sides are vertical, and the vertical orientation of the tablets W and W1 means that the tablets W and W1 are in a vertical orientation. The long sides of W and W1 are in the vertical direction and the short sides are in the horizontal direction, and when the tablets W and W1 are oriented vertically, the posture is higher than when the tablets W and W1 are oriented horizontally. Become.

内側搬送部11の回転によって外側搬送部12に乗り上げた錠剤Wは、溝部12Aの径方向の内端部12nから溝部12Aに入り込み、外側搬送部12の回転による遠心力と、後述する物品案内部部27によって、溝部12Aから収容溝12Bに案内されて収容溝12Bに収容される。 The tablet W that rides on the outer conveyor part 12 due to the rotation of the inner conveyor part 11 enters the groove part 12A from the radially inner end 12n of the groove part 12A, and is affected by the centrifugal force caused by the rotation of the outer conveyor part 12 and the article guide section described below. It is guided from the groove part 12A to the accommodation groove 12B by the part 27 and is accommodated in the accommodation groove 12B.

図3、図4に示すように、収容溝12Bは、溝部12Aに対して外側搬送部12の径方向外方に位置している。収容溝12Bは、平面視で錠剤Wよりも少しだけ大きい円形に形成されており、溝部12Aの底面12bよりも下方に窪んでいる、または、溝部12Aと同一高さとしてもよい。 As shown in FIGS. 3 and 4, the accommodation groove 12B is located radially outward of the outer conveyance section 12 with respect to the groove portion 12A. The accommodation groove 12B is formed into a circular shape that is slightly larger than the tablet W in a plan view, and may be recessed below the bottom surface 12b of the groove portion 12A, or may be at the same height as the groove portion 12A.

具体的には、収容溝12Bは、溝部12Aの底面12bよりも下方に位置する環状の載置面12dを有する底壁12Cを備えている。底壁12Cには載置面12dの内方に位置し、検査用の光が通過する円形の開口部12cが形成されている。すなわち、載置面12dは、円形の開口部12cを取り囲むように開口部12cの径方向外方に設けられており、環状の載置面12dには開口部12cを上方から閉止するように錠剤Wが載置される。 Specifically, the accommodation groove 12B includes a bottom wall 12C having an annular mounting surface 12d located below the bottom surface 12b of the groove portion 12A. A circular opening 12c is formed in the bottom wall 12C, located inside the mounting surface 12d, and through which inspection light passes. That is, the mounting surface 12d is provided radially outward of the circular opening 12c so as to surround the circular opening 12c, and a tablet is placed on the annular mounting surface 12d so as to close the opening 12c from above. W is placed.

収容溝12Bは、底壁12Cから上方に延在し、錠剤Wの外周側面Waを取り囲む周壁12Dを備えており、収容溝12Bには錠剤Wが嵌まった状態で収容される。 The accommodation groove 12B is provided with a peripheral wall 12D that extends upward from the bottom wall 12C and surrounds the outer circumferential side face Wa of the tablet W, and the tablet W is accommodated in the accommodation groove 12B in a fitted state.

具体的には、溝部12Aの底面12bと収容溝12Bの載置面12dの段差と、溝部12Aの上面12aと収容溝12Bの載置面12dの段差とによって収容溝12Bの周壁12Dが形成されている。 Specifically, the peripheral wall 12D of the accommodation groove 12B is formed by the step between the bottom surface 12b of the groove 12A and the placement surface 12d of the accommodation groove 12B, and the step between the top surface 12a of the groove 12A and the placement surface 12d of the accommodation groove 12B. ing.

開口部12cは、外側搬送部12の平面視において錠剤Wの外径よりも小径に形成されているので、収容溝12Bに錠剤Wが収容された状態では開口部12cが上方から目視不能となり、錠剤Wが開口部12cから落下することを防止できる。 Since the opening 12c is formed to have a smaller diameter than the outer diameter of the tablet W in a plan view of the outer conveyance section 12, the opening 12c is not visible from above when the tablet W is stored in the storage groove 12B. It is possible to prevent the tablet W from falling from the opening 12c.

外側搬送部12の回転中心軸から全ての収容溝12Bの中心部までの距離は、同一の距離となっており、錠剤Wが収容溝12Bに収容された状態において、錠剤Wは、外側搬送部12の回転方向に一列に整列される。すなわち、収容溝12Bの中心部(開口部12cの中心部)を回転方向に結んだ線は円となる。これにより、外側搬送部12が回転すると、収容溝12Bに収容された錠剤Wは、外側搬送部12の回転方向に一列に整列される。 The distance from the rotation center axis of the outer conveyance section 12 to the center of all the storage grooves 12B is the same distance, and in the state where the tablet W is accommodated in the accommodation groove 12B, the tablet W is transferred to the outer conveyance section. 12 are aligned in a line in the rotational direction. In other words, a line connecting the center of the accommodation groove 12B (the center of the opening 12c) in the rotation direction forms a circle. Thereby, when the outer conveyance section 12 rotates, the tablets W accommodated in the storage groove 12B are aligned in a line in the rotation direction of the outer conveyance section 12.

また、錠剤Wが収容溝12Bに収容された状態においては錠剤Wの外周側面Waと周壁12Dの隙間が極小となる。これにより、錠剤Wと周壁12Dの隙間から光が漏出することや、錠剤Wと周壁12Dの隙間に光が入り込むことを防止できる。すなわち、周壁12Dは、錠剤Wの外周側面Waから後述する光検出部32に入射する光を遮る。本実施形態の周壁12Dは、遮光部を構成し、錠剤Wの外周側面Waは、物品の外周側面を構成する。 Furthermore, when the tablet W is accommodated in the accommodation groove 12B, the gap between the outer peripheral side surface Wa of the tablet W and the peripheral wall 12D becomes extremely small. This can prevent light from leaking through the gap between the tablet W and the peripheral wall 12D and preventing light from entering the gap between the tablet W and the peripheral wall 12D. That is, the peripheral wall 12D blocks light that enters the light detection section 32, which will be described later, from the outer peripheral side surface Wa of the tablet W. The peripheral wall 12D of this embodiment constitutes a light shielding part, and the outer peripheral side surface Wa of the tablet W constitutes the outer peripheral side surface of the article.

なお、錠剤Wの外周側面Waと周壁12Dの隙間は、周壁12Dによって錠剤Wの外周側面Waから光が漏れることや外周側面Waから光が入り込むことを防止でき、錠剤Wが収容溝12Bに確実に収容される隙間に設定されていることを条件とする。 Note that the gap between the outer circumferential side surface Wa of the tablet W and the circumferential wall 12D is such that the circumferential wall 12D can prevent light from leaking from the outer circumferential side surface Wa of the tablet W and light from entering from the outer circumferential side surface Wa of the tablet W, and the tablet W can be securely placed in the storage groove 12B. The condition is that it is set in a gap that is accommodated in

図4に示すように、収容溝12Bに錠剤Wが収容された状態において、錠剤Wの高さ方向の寸法a、すなわち、収容溝12Bの載置面12dから錠剤Wの上面までの寸法aは、収容溝12Bの載置面12dから溝部12Aの上面12aの高さ方向の寸法bよりも大きい。 As shown in FIG. 4, when the tablet W is accommodated in the accommodation groove 12B, the dimension a in the height direction of the tablet W, that is, the dimension a from the placement surface 12d of the accommodation groove 12B to the upper surface of the tablet W is , is larger than the dimension b in the height direction from the placement surface 12d of the accommodation groove 12B to the upper surface 12a of the groove portion 12A.

これにより、収容溝12Bに錠剤Wが収容された状態において、錠剤Wの上面は、溝部12Aの上面12aよりも上方に突出している。
なお、収容溝12Bに錠剤Wが収容された状態において、錠剤Wの高さ方向の寸法aを収容溝12Bの載置面12dから溝部12Aの上面12aまでの高さ方向の寸法bよりも小さくしてもよい。この場合、収容溝12Bに錠剤Wが収容された状態において、錠剤Wの上面は、溝部12Aの上面12aよりも下方に位置する。
As a result, when the tablet W is accommodated in the accommodation groove 12B, the upper surface of the tablet W protrudes higher than the upper surface 12a of the groove portion 12A.
Note that when the tablet W is accommodated in the accommodation groove 12B, the height dimension a of the tablet W is smaller than the height dimension b from the placement surface 12d of the accommodation groove 12B to the upper surface 12a of the groove portion 12A. You may. In this case, when the tablet W is accommodated in the accommodation groove 12B, the upper surface of the tablet W is located below the upper surface 12a of the groove portion 12A.

図1に示すように、物品搬送装置2には、物品規制部25が設けられている。物品規制部25は、錠剤Wが溝部12Aに1つだけ供給されるように錠剤Wの供給数を規制し、錠剤Wを外側搬送部12の回転方向に1例に整列させる。 As shown in FIG. 1, the article conveyance device 2 is provided with an article regulation section 25. The article regulation section 25 regulates the number of tablets W to be supplied so that only one tablet W is supplied to the groove section 12A, and aligns the tablets W in one example in the rotational direction of the outer conveyance section 12.

物品規制部25は、外側搬送部12の回転方向に一定の長さで湾曲して延在し、かつ、上下方向に延在するガイド板から構成されており、供給容器10を支持する本体フレームに固定されている。 The article regulating section 25 is composed of a guide plate that curves and extends at a constant length in the rotational direction of the outer conveyance section 12 and extends in the vertical direction, and includes a main body frame that supports the supply container 10. is fixed.

物品規制部25は、物品投入位置P1に対して外側搬送部12の回転方向の下流側の規制位置P2に設けられている。換言すれば、物品投入位置P1は、物品搬送装置2の平面視で物品規制部25に対して上流側に設置されている。ここで、外側搬送部12の回転方向と錠剤Wの搬送方向は、同一方向である。 The article regulation section 25 is provided at a regulation position P2 on the downstream side in the rotational direction of the outer conveyance section 12 with respect to the article input position P1. In other words, the article input position P1 is installed on the upstream side with respect to the article regulating section 25 in a plan view of the article conveying device 2. Here, the rotational direction of the outer conveyance section 12 and the conveyance direction of the tablet W are the same direction.

内側搬送部11から溝部12Aの径方向の内端部12nを通して溝部12Aに1つの錠剤Wが供給されると、物品規制部25には錠剤Wの径方向の外端部が接触する。すなわち、物品規制部25と溝部12Aの内端部12nにおける外側搬送部12の径方向の寸法は、錠剤Wが溝部12Aから内側搬送部11に落ちないように、錠剤Wの直径と同じ寸法、錠剤Wの直径よりも少し大きい寸法、または錠剤Wの直径よりも少し小さい寸法に設定されている。これにより、物品規制部25によって溝部12Aに錠剤Wが1つだけ供給されるように錠剤Wの供給数が規制される。 When one tablet W is supplied from the inner conveying section 11 to the groove 12A through the radially inner end 12n of the groove 12A, the radially outer end of the tablet W comes into contact with the article regulating section 25. That is, the radial dimension of the outer conveying section 12 at the inner end 12n of the article regulating section 25 and the groove 12A is the same as the diameter of the tablet W, so that the tablet W does not fall from the groove 12A into the inner conveying section 11. The size is set to be slightly larger than the diameter of the tablet W or slightly smaller than the diameter of the tablet W. Thereby, the number of tablets W to be supplied is regulated by the article regulating section 25 so that only one tablet W is supplied to the groove 12A.

また、溝部12Aに1つだけ供給された錠剤Wは、物品規制部25によって外側搬送部12の径方向外方に移動することが規制され、外側搬送部12の回転方向に一列に整列した状態で物品検査位置P5に向かって搬送される。 Moreover, the tablet W supplied only one to the groove 12A is restricted from moving radially outward of the outer conveyance section 12 by the article regulating section 25, and is aligned in a line in the rotational direction of the outer conveyance section 12. The article is transported toward the article inspection position P5.

物品搬送装置2には物品調整部26が設けられている。物品調整部26は、物品規制部25に対して外側搬送部12の回転方向の下流側の物品調整位置P3に設けられており、溝部12Aに正規の姿勢で位置していない錠剤Wを溝部12Aで正規の姿勢に戻すとともに、溝部12Aからはみ出している錠剤Wを溝部12Aから除去する。ここで、錠剤Wの正規の姿勢とは、例えば、溝部12Aから収容溝12Bに円滑に移動して収容溝12Bに横向きで収容可能な姿勢である。 The article conveyance device 2 is provided with an article adjustment section 26 . The article adjustment section 26 is provided at an article adjustment position P3 on the downstream side in the rotational direction of the outer conveyance section 12 with respect to the article regulation section 25, and removes tablets W that are not positioned in the groove 12A in a normal posture. At the same time, the tablet W protruding from the groove 12A is removed from the groove 12A. Here, the normal posture of the tablet W is, for example, a posture in which the tablet W can smoothly move from the groove portion 12A to the accommodation groove 12B and be housed sideways in the accommodation groove 12B.

物品調整部26は、ブラシやエアー、排除板などから構成されており、溝部12Aに供給された錠剤Wが外側搬送部12の上面12aに乗り上げた場合に、錠剤を溝部12Aにおいて正常な姿勢となるように調整し、または溝部12Aから排除する。 The article adjustment section 26 is composed of a brush, air, a removal plate, etc., and when the tablet W supplied to the groove section 12A rides on the upper surface 12a of the outer conveyance section 12, it adjusts the tablet to a normal posture in the groove section 12A. or remove it from the groove 12A.

また、1つの錠剤Wが姿勢不良(縦向き)になったときに、当該錠剤Wを溝部12Aから排除する。溝部12Aから排除された錠剤Wは内側搬送部11に戻される。 Further, when one tablet W has a bad posture (vertical orientation), the tablet W is removed from the groove 12A. The tablet W removed from the groove 12A is returned to the inner conveyance section 11.

具体的に、物品調整部26は、溝部12Aで正常な姿勢となる錠剤Wの上面よりも上方に錠剤Wが位置している場合には、錠剤Wの上面よりも上方にエアー供給することや、排除板を作用させることにより、姿勢不良となる錠剤Wを調整(姿勢矯正または排除)する。 Specifically, when the tablet W is located above the top surface of the tablet W that assumes a normal posture in the groove 12A, the article adjustment section 26 supplies air above the top surface of the tablet W. , the tablet W with poor posture is adjusted (posture corrected or eliminated) by operating the exclusion plate.

物品搬送装置2には物品案内部27が設けられている。物品案内部27は、物品調整部26に対して外側搬送部12の回転方向の下流側の物品案内位置P4に設けられており、溝部12Aに供給された錠剤Wを溝部12Aに沿って収容溝12Bに案内する。物品案内部27は、外側搬送部12の回転方向に一定の長さで湾曲して延在し、かつ、上下方向に延在するガイド板から構成されており、供給容器10を支持する本体フレームに固定されている。 The article conveyance device 2 is provided with an article guide section 27 . The article guide section 27 is provided at an article guide position P4 on the downstream side in the rotational direction of the outer conveyance section 12 with respect to the article adjustment section 26, and stores the tablets W supplied to the groove section 12A along the groove section 12A. I will guide you to 12B. The article guide section 27 is composed of a guide plate that curves and extends at a constant length in the rotational direction of the outer conveyance section 12 and extends in the vertical direction, and includes a main body frame that supports the supply container 10. is fixed.

物品案内部27は、外側搬送部12の回転方向において溝部12Aの内端部12nから外端部12mに向かうように一定の長さで延在し、かつ上下方向に延在するガイド板から構成されている。物品案内部27は、上流端部27aが外側搬送部12の径方向で溝部12Aの内端部12nよりも内側搬送部11側に位置しており、下流端部27bが外側搬送部12の径方向で収容溝12Bよりも溝部12Aの内端部12n側に位置し、かつ、溝部12Aの外端部12m付近に位置している。 The article guide section 27 is constituted by a guide plate that extends a certain length from the inner end 12n of the groove section 12A toward the outer end 12m in the rotational direction of the outer conveyance section 12, and also extends in the vertical direction. has been done. The article guide part 27 has an upstream end 27a located closer to the inner transport part 11 than the inner end 12n of the groove part 12A in the radial direction of the outer transport part 12, and a downstream end 27b located in the radial direction of the outer transport part 12. It is located closer to the inner end 12n of the groove 12A than the accommodation groove 12B in terms of direction, and is located near the outer end 12m of the groove 12A.

物品案内部27は、規制位置P2において収容溝12Bの内端部12n側で外側搬送部12の回転方向に一列に整列された錠剤Wを、外側搬送部12の回転に伴って溝部12Aに沿って収容溝12B側に移動させ、収容溝12Bに収容する。 The article guide section 27 moves the tablets W aligned in a line in the rotational direction of the outer conveyance section 12 on the inner end 12n side of the accommodation groove 12B at the regulation position P2 along the groove section 12A as the outer conveyance section 12 rotates. and move it to the accommodation groove 12B side and accommodate it in the accommodation groove 12B.

物品案内位置P4において、外側搬送部12の下方には図示しない吸引ノズルが設けられている。吸引ノズルは、物品案内位置P4で溝部12Aから収容溝12Bに錠剤Wが案内される過程で、収容溝12Bの開口部12cを通して錠剤Wを吸引して収容溝12Bに収容する。 At the article guide position P4, a suction nozzle (not shown) is provided below the outer conveyance section 12. The suction nozzle sucks the tablet W through the opening 12c of the storage groove 12B and stores it in the storage groove 12B in the process of guiding the tablet W from the groove 12A to the storage groove 12B at the article guide position P4.

収容溝12Bに収容された錠剤Wは、外側搬送部12の回転によって物品検査部3に搬送される。図1に示すように、物品検査部3は、外側搬送部12の回転方向で物品案内位置P4よりも下流側の物品検査位置P5に設けられている。 The tablet W accommodated in the accommodation groove 12B is conveyed to the article inspection section 3 by the rotation of the outer conveyance section 12. As shown in FIG. 1, the article inspection section 3 is provided at an article inspection position P5 downstream of the article guide position P4 in the rotational direction of the outer conveyance section 12.

物品搬送装置2には物品阻止部28が設けられている。物品阻止部28は、物品案内部27の外側搬送部12の回転方向の途中から外側搬送部12の回転方向で物品検査位置P5よりも下流側まで設けられている。 The article conveying device 2 is provided with an article blocking section 28 . The article blocking section 28 is provided from the middle of the article guide section 27 in the rotation direction of the outer conveyance section 12 to the downstream side of the article inspection position P5 in the rotation direction of the outer conveyance section 12.

物品阻止部28は、外側搬送部12の回転方向に湾曲して一定の長さで延在し、かつ、上下方向に延在するガイド板から構成されており、供給容器10を支持する本体フレームに固定されている。 The article blocking section 28 is composed of a guide plate that is curved in the rotation direction of the outer conveyance section 12 and extends at a constant length, and also extends in the vertical direction, and is connected to the main body frame that supports the supply container 10. is fixed.

物品阻止部28は、物品案内部27によって収容溝12Bに収容された錠剤Wが外側搬送部12の回転による遠心力によって収容溝12Bから径方向外方に移動することを阻止する。 The article blocking section 28 prevents the tablet W accommodated in the accommodation groove 12B by the article guide section 27 from moving radially outward from the accommodation groove 12B due to the centrifugal force caused by the rotation of the outer conveyance section 12.

図3、図4に示すように、底壁12Cには直線状の渡り板12gが設けられている。渡り板12gは、開口部12cの径方向内端部12sと径方向外端部12tとを連結し、開口部12cの一部を閉じている。換言すれば、渡り板12gは、開口部12cの径方向外端部12tから径方向内端部12sに延在している、または、開口部12cの径方向内端部12sから径方向外端部12tに延在している。開口部12cの一部は、開口部12cの外側搬送部12の回転方向の中央部である。 As shown in FIGS. 3 and 4, a linear span plate 12g is provided on the bottom wall 12C. The spanning plate 12g connects the radially inner end 12s and the radially outer end 12t of the opening 12c, and closes a portion of the opening 12c. In other words, the gangplank 12g extends from the radially outer end 12t of the opening 12c to the radially inner end 12s, or from the radially inner end 12s of the opening 12c to the radially outer end. It extends to 12t. A portion of the opening 12c is a central portion of the opening 12c in the rotational direction of the outer conveyance section 12.

すなわち、渡り板12gは、外側搬送部12の回転方向の両側(上流側と下流側)に開口部12cが形成されるように、開口部12cの上方を通過して開口部12cの径方向内端部12sと径方向外端部12tとを連結している。 That is, the spanning plate 12g passes above the opening 12c and extends to the radially inner end of the opening 12c so that the opening 12c is formed on both sides (upstream side and downstream side) of the outer conveyance section 12 in the rotational direction. The portion 12s and the radially outer end portion 12t are connected.

渡り板12gの上面は、載置面12dと同じ高さ位置に位置している。すなわち、渡り板12gの上面と載置面12dは、同一平面上に位置している。なお、渡り板12gは、錠剤Wの形状に合わせて下方に窪ませることや、上方に突起状にすることにより、同一平面上からずれるように構成してもよい。 The upper surface of the connecting plate 12g is located at the same height as the mounting surface 12d. That is, the upper surface of the connecting plate 12g and the mounting surface 12d are located on the same plane. Note that the spanning plate 12g may be configured to be deviated from the same plane by being recessed downward in accordance with the shape of the tablet W or by forming a protrusion upward.

これにより、錠剤Wは、載置面12dと渡り板12gに載置された状態で収容溝12Bに収容される。本実施形態の渡り板12gは、載置補助部を構成する。 Thereby, the tablet W is accommodated in the accommodation groove 12B while being placed on the placement surface 12d and the spanning plate 12g. The gangplank 12g of this embodiment constitutes a placement auxiliary part.

図3に示すように、溝部12Aは、側壁12E、12Fを有する。側壁12E、12Fは、溝部12Aの底壁12Cから上方に延在しており、収容溝12Bの周壁12Dに連絡されている。すなわち、側壁12E、12Fは、周壁12Dに連続しており、周壁12Dと一体である。 As shown in FIG. 3, the groove portion 12A has side walls 12E and 12F. The side walls 12E, 12F extend upward from the bottom wall 12C of the groove portion 12A, and communicate with the peripheral wall 12D of the housing groove 12B. That is, the side walls 12E, 12F are continuous with the peripheral wall 12D and are integral with the peripheral wall 12D.

側壁12E、12Fは、外側搬送部12の径方向内方から径方向外方に延在しており、外側搬送部12の回転方向で対向している。側壁12Eは、外側搬送部12の回転方向において側壁12Fに対して外側搬送部12の上流側に設けられている。 The side walls 12E and 12F extend from the inside in the radial direction to the outside in the radial direction of the outer conveyance section 12, and are opposed to each other in the rotational direction of the outer conveyance section 12. The side wall 12E is provided upstream of the outer conveyance section 12 with respect to the side wall 12F in the rotational direction of the outer conveyance section 12.

これにより、外側搬送部12の回転時に、内側搬送部11から溝部12Aに供給される錠剤Wは、側壁12Eに接触しながら溝部12Aに沿って収容溝12Bに移動する。渡り板12gは、側壁12Eの延在方向と平行に延在している。 Thereby, when the outer conveyance section 12 rotates, the tablet W supplied from the inner conveyance section 11 to the groove 12A moves along the groove 12A to the storage groove 12B while contacting the side wall 12E. The span plate 12g extends parallel to the extending direction of the side wall 12E.

物品案内位置P4において、錠剤Wは物品案内部27によって溝部12Aから収容溝12Bに移動する。 At the article guide position P4, the tablet W is moved by the article guide section 27 from the groove section 12A to the storage groove 12B.

具体的には、図1、図6に示すように、錠剤Wは、物品案内位置P4において物品案内部27によって溝部12Aから収容溝12Bに向かって案内される(X1、X2参照)。このとき、錠剤Wは、溝部12Aの側壁12Eに沿って収容溝12B側に移動する。 Specifically, as shown in FIGS. 1 and 6, the tablet W is guided from the groove 12A toward the accommodation groove 12B by the article guide section 27 at the article guide position P4 (see X1 and X2). At this time, the tablet W moves toward the accommodation groove 12B along the side wall 12E of the groove 12A.

次いで、錠剤Wは、物品案内部27によって溝部12Aに案内されるときに、X3で示すように、進行方向の先端部Wu(図6(c)参照)から収容溝12Bに向かって落下する。 Next, when the tablet W is guided to the groove 12A by the article guide section 27, it falls toward the accommodation groove 12B from the leading end Wu (see FIG. 6(c)) in the traveling direction, as indicated by X3.

ここで、渡り板12gは、側壁12Eの延在方向と平行に延在している。これに加えて、錠剤Wは、略円柱状に形成されている。このため、錠剤Wの進行方向の先端部Wuが収容溝12Bに向かって落下すると、錠剤Wの落下方向に渡り板12gを位置させることができ、渡り板12gに錠剤Wの先端部Wuを確実に接触させることができる。 Here, the connecting plate 12g extends parallel to the extending direction of the side wall 12E. In addition, the tablet W is formed into a substantially cylindrical shape. Therefore, when the leading end Wu of the tablet W in the traveling direction falls toward the accommodation groove 12B, the connecting plate 12g can be positioned in the falling direction of the tablet W, and the leading end Wu of the tablet W can be reliably brought into contact with the connecting plate 12g. can be done.

すなわち、渡り板12gが側壁12Eの延在方向と平行に延在している場合には、渡り板12gに対する円柱形状の錠剤Wの先端部Wuの接触点は1点となり、そこに渡り板12gを設置することにより、錠剤Wの先端部Wuを渡り板12gに確実に接触させることができる。 That is, when the connecting plate 12g extends parallel to the extending direction of the side wall 12E, the contact point of the tip Wu of the cylindrical tablet W with the connecting plate 12g is one point, and the connecting plate 12g is installed there. Thereby, the tip Wu of the tablet W can be reliably brought into contact with the spanning plate 12g.

物品搬送装置2は、物品案内位置P4において吸引ノズルによって開口部12cを通して吸引を行っている。これにより、錠剤Wは吸引ノズルによって吸引されてその底面が渡り板12gに接触しながら、収容溝12Bの径方向内端部12sから径方向外端部12tに移動し、開口部12cの上方に位置するようにして収容溝12Bに収容される(図6(d)参照)。錠剤Wは、収容溝12Bに収容された状態で外側搬送部12の回転方向に一列に整列され、物品検査位置P5に搬送される。 The article conveyance device 2 performs suction through the opening 12c using the suction nozzle at the article guide position P4. As a result, the tablet W is sucked by the suction nozzle and moves from the radially inner end 12s to the radially outer end 12t of the storage groove 12B while its bottom surface contacts the spanning plate 12g, and is positioned above the opening 12c. It is accommodated in the accommodation groove 12B in this manner (see FIG. 6(d)). The tablets W accommodated in the accommodation groove 12B are aligned in a line in the rotational direction of the outer conveyance section 12 and conveyed to the article inspection position P5.

図7に示すように、物品検査部3は、光照射部31と光検出部32から構成されている。物品検査部3は、物品検査位置P5において光照射部31から広帯域の光Lを、開口部12c側から収容溝12Bに収容された錠剤Wに照射し、錠剤Wを透過した光を光検出部32によって検出する。 As shown in FIG. 7, the article inspection section 3 includes a light irradiation section 31 and a light detection section 32. The article inspection section 3 irradiates the tablet W accommodated in the storage groove 12B from the opening 12c side with broadband light L from the light irradiation section 31 at the article inspection position P5, and transmits the light transmitted through the tablet W to the photodetection section. Detected by 32.

光照射部31は、光源31a、ライトガイド31b、集光レンズ31cを備えている。光源31aは、検査対象の錠剤Wに広帯域の光を照射するため、例えばハロゲンランプから構成されている。光源31a、ライトガイド31b、集光レンズ31cは、図示しない放熱フィンが形成された図示しないケースと共に一体的に組み立てられた光源ユニットを構成しており、光源ユニットは、供給容器10を支持する本体フレームに取付けられている。 The light irradiation section 31 includes a light source 31a, a light guide 31b, and a condenser lens 31c. The light source 31a is composed of, for example, a halogen lamp in order to irradiate the tablet W to be inspected with broadband light. The light source 31a, the light guide 31b, and the condensing lens 31c constitute a light source unit that is integrally assembled with a case (not shown) in which heat radiation fins (not shown) are formed, and the light source unit includes a main body that supports the supply container 10. attached to the frame.

ライトガイド31bは、ガラス光ファイバを多数束ねて構成されており、光源31aからの光を集光する集光レンズ31cに導く。集光レンズ31cは、ライトガイド31bからの光を物品検査位置P5で錠剤Wに集光する。 The light guide 31b is configured by bundling a large number of glass optical fibers, and guides the light from the light source 31a to a condenser lens 31c that condenses the light. The condensing lens 31c condenses the light from the light guide 31b onto the tablet W at the article inspection position P5.

光照射部31は、光源31aからの広帯域の光を、ライトガイド31bを介して集光レンズ31cに出射し、集光レンズ31cにより物品検査位置P5で錠剤Wの上面全てをカバーするように集光レンズ31cの倍率(集光レンズ31c、光源31aと錠剤Wの位置)を調整し、物品検査位置P5において光源31aからの光を効率よく錠剤Wに照射する。 The light irradiation unit 31 emits broadband light from the light source 31a to the condenser lens 31c via the light guide 31b, and condenses the light so as to cover the entire upper surface of the tablet W at the article inspection position P5 by the condenser lens 31c. The magnification of the optical lens 31c (the positions of the condensing lens 31c, the light source 31a, and the tablet W) is adjusted to efficiently irradiate the tablet W with light from the light source 31a at the article inspection position P5.

光検出部32は、光ファイバ32aと分光器32bとを備えて一体的に組み立てられた光検出ユニットを構成しており、図示しない保持手段に一体的に保持されて供給容器10を支持する本体フレームに取付けられている。 The photodetector 32 constitutes an integrally assembled photodetector unit including an optical fiber 32a and a spectroscope 32b, and is integrally held by a holding means (not shown) to support the supply container 10. attached to the frame.

光検出部32において、物品検査位置P5で錠剤Wを透過した光は、光ファイバ32aの受光部としての入射面の端面(入射開口部)から入光する。入射面の端面から入光する光が光ファイバ32a内を通過して分光器32bに到達すると、分光器32bが光の波長による回折角度の差を利用したグレーティングによる分光を行う。 In the light detection section 32, the light that has passed through the tablet W at the article inspection position P5 enters from the end surface (incidence opening) of the incident surface as a light receiving section of the optical fiber 32a. When light entering from the end face of the incident surface passes through the optical fiber 32a and reaches the spectroscope 32b, the spectroscope 32b performs spectroscopy using a grating that utilizes the difference in the diffraction angle depending on the wavelength of the light.

物品検査部3は、光検出部32で得られた分光特性の信号を処理し、信号を処理した結果から錠剤Wの品質の良否判定を行う。 The article inspection section 3 processes the signal of the spectral characteristics obtained by the light detection section 32, and determines whether the quality of the tablet W is good or bad based on the result of processing the signal.

図1に示すように、物品検査位置P5よりも外側搬送部12の回転方向の下流側にはNG品回収部35、全品回収部36およびOK品回収部37が外側搬送部12の回転方向に所定の間隔をおいて設けられている。 As shown in FIG. 1, an NG product collection section 35, an all-product collection section 36, and an OK product collection section 37 are located downstream of the article inspection position P5 in the rotation direction of the outer transport section 12. They are provided at predetermined intervals.

物品搬送装置2は、物品検査部3が錠剤Wを不良品(NG品)と判定すると、当該不良品と判定された錠剤Wが物品検査部3に対して外側搬送部12の回転方向の下流側のNG品選別位置P6まで搬送されてきたときに、例えば、外側搬送部12の径方向の内側から錠剤Wにエアーを吹き付けて収容溝12BからNG品回収部35に排出する。なお、NG品選別位置P6で外側搬送部12の径方向外方から錠剤Wを吸引して収容溝12BからNG品回収部35に排出してもよい。 When the article inspection section 3 determines that the tablet W is a defective product (NG product), the article conveyance device 2 transports the tablet W determined to be defective to the article inspection section 3 downstream in the rotational direction of the outer conveyance section 12. When the tablet W is transported to the NG product sorting position P6 on the side, air is blown onto the tablet W from the radially inner side of the outer transport section 12, and the tablet W is discharged from the storage groove 12B to the NG product recovery section 35. Note that the tablets W may be sucked from the outside in the radial direction of the outer conveyance section 12 at the NG product sorting position P6 and discharged from the storage groove 12B to the NG product recovery section 35.

一方、物品検査部3が錠剤Wを正常品(OK品)と判定すると、当該正常品と判定された錠剤WがNG品選別位置P6からOK品選別位置P7まで搬送されてきたときに、例えば、外側搬送部12の径方向の内側から錠剤Wにエアーを吹き付けて収容溝12BからOK品回収部37に排出する。なお、OK品選別位置P7で外側搬送部12の径方向外方から錠剤Wを吸引して収容溝12BからOK品回収部37に排出してもよい。 On the other hand, when the article inspection unit 3 determines that the tablet W is a normal product (OK product), when the tablet W determined to be a normal product is transported from the NG product sorting position P6 to the OK product sorting position P7, for example, , air is blown onto the tablets W from the radially inner side of the outer conveyance section 12, and the tablets W are discharged from the storage groove 12B to the OK product recovery section 37. Note that the tablets W may be sucked from the outside in the radial direction of the outer conveyance section 12 at the OK product sorting position P7 and discharged from the storage groove 12B to the OK product recovery section 37.

全品回収部36は、外側搬送部12の回転方向でNG品選別位置P6とOK品選別位置P7の間の全排出位置P8に設けられている。 The all-product collection section 36 is provided at a full-discharge position P8 between the NG product sorting position P6 and the OK product sorting position P7 in the rotational direction of the outer conveyance section 12.

全品回収部36は、物品検査装置1の運転開始時や、非常停止後の復帰動作後や、NG排出を失敗した錠剤Wなど、正常な検査ができなかった、または、排出を失敗した錠剤Wなどを回収するものであり、例えば、外側搬送部12の径方向の内側から錠剤Wにエアーを吹き付けて収容溝12Bから全品回収部36に排出する。 The all-item collection unit 36 collects tablets W that could not be inspected normally or failed to be ejected, such as when the product inspection device 1 starts operating, after a recovery operation after an emergency stop, or for tablets W that failed to eject NG. For example, air is blown onto the tablets W from the inside of the outer conveyance section 12 in the radial direction, and the tablets W are discharged from the storage groove 12B to the all-product recovery section 36.

なお、全排出位置P8で外側搬送部12の径方向外方から錠剤Wを吸引して収容溝12Bから全品回収部36に排出してもよい。 Note that the tablets W may be sucked from the outside in the radial direction of the outer conveyance section 12 at the full discharge position P8 and discharged from the storage groove 12B to the full product collection section 36.

また、外側搬送部12の回転方向でNG品回収部35の下流側の確認位置P9に確認センサ38を設け、確認センサ38によってNG品選別位置P6で不良品が排出されたか否かを確認してもよい。このようにすれば、不良品の選別の信頼性を向上できる。 Further, a confirmation sensor 38 is provided at a confirmation position P9 on the downstream side of the NG product collecting section 35 in the rotational direction of the outer conveyance section 12, and the confirmation sensor 38 confirms whether or not a defective product has been discharged at the NG product sorting position P6. It's okay. In this way, the reliability of selecting defective products can be improved.

次に、本実施形態の物品検査装置1の効果を説明する。
本実施形態の物品検査装置1は、錠剤Wを収容して回転方向に整列する複数の収容溝12Bが設けられ、収容溝12Bに収容された錠剤Wを物品検査位置P5に搬送する回転自在な外側搬送部12を有し、物品検査位置P5で錠剤Wを透過した光の分光特性に基づいて錠剤Wの品質を検査する。
Next, the effects of the article inspection device 1 of this embodiment will be explained.
The article inspection device 1 of this embodiment is provided with a plurality of accommodation grooves 12B that accommodate tablets W and are arranged in the rotation direction, and is rotatable to convey the tablets W accommodated in the accommodation grooves 12B to an article inspection position P5. It has an outer conveyance section 12, and inspects the quality of the tablet W based on the spectral characteristics of the light transmitted through the tablet W at the article inspection position P5.

収容溝12Bは、光が通過する開口部12cが形成され、錠剤Wが載置される載置面12dを有する底壁12Cと、底壁12Cから上方に延在し、錠剤Wの外周側面Waを取り囲む周壁12Dとを備えている。 The accommodation groove 12B includes a bottom wall 12C having an opening 12c through which light passes and a placement surface 12d on which the tablet W is placed, and a bottom wall 12C extending upward from the bottom wall 12C and facing the outer circumferential surface Wa of the tablet W. A peripheral wall 12D surrounding the.

これにより、錠剤Wを底壁12Cと周壁12Dによって囲まれる空間に設置でき、物品検査部3において光検出部32によって適切な光の分析を行うことができる。 Thereby, the tablet W can be installed in the space surrounded by the bottom wall 12C and the peripheral wall 12D, and the light detection section 32 can perform appropriate light analysis in the article inspection section 3.

具体的には、錠剤Wを透過した光の分光特性に基づいて錠剤Wの品質を検査する場合には、錠剤Wを透過する際の光の減衰が大きく、錠剤Wを透過した光(透過光)は、錠剤Wに照射される光に比べ非常に微弱である。 Specifically, when inspecting the quality of the tablet W based on the spectral characteristics of the light transmitted through the tablet W, the attenuation of the light when transmitting the tablet W is large, and the light transmitted through the tablet W (transmitted light ) is very weak compared to the light irradiated onto the tablet W.

このため、光照射部31から照射された光が錠剤Wの外周側面Waから漏れて光検出部32に入ると、すなわち、光照射部31から照射された光が錠剤Wを透過せずに光検出部32に入ると(この光を迷光という)、光検出部32でサチュレーション(光飽和)を生じることや、錠剤Wを透過した光が迷光と混じることにより、光検出部32で適切な光の分析を行うことができない。 Therefore, if the light irradiated from the light irradiation section 31 leaks from the outer circumferential side surface Wa of the tablet W and enters the light detection section 32, that is, the light irradiated from the light irradiation section 31 does not pass through the tablet W. When entering the detection section 32 (this light is referred to as stray light), saturation occurs in the light detection section 32, and the light that has passed through the tablet W mixes with stray light, so that the light detection section 32 detects appropriate light. cannot be analyzed.

本実施形態の物品検査装置1の収容溝12Bが、光が通過する開口部12cが形成され、錠剤Wが載置される載置面12dを有する底壁12Cと、錠剤Wの外周側面Waを取り囲む周壁12Dとを備えている。 The accommodation groove 12B of the article inspection device 1 of this embodiment has a bottom wall 12C having an opening 12c through which light passes and a placement surface 12d on which the tablet W is placed, and an outer circumferential side surface Wa of the tablet W. A surrounding peripheral wall 12D is provided.

これにより、錠剤Wが収容溝12Bに収容された状態において錠剤Wの外周側面Waと周壁12Dの隙間を極小にでき、錠剤Wの外周側面Waから光検出部32に入射する光を周壁12Dによって遮ることができる。すなわち、光照射部31から錠剤Wに照射された光を錠剤Wに効率よく透過させることができる。また、開口部12cが錠剤Wに対して十分小さい場合は、収容溝12Bの下方向への段差をなくした収容溝12Bとして測定しても、迷光と混じることを防止できる。このため、光検出部32でサチュレーションが生じることや、錠剤Wを通過した光が迷光と混じることを防止でき、光検出部32で適切な光の分析を行うことができる。 This makes it possible to minimize the gap between the outer circumferential side surface Wa of the tablet W and the circumferential wall 12D in a state in which the tablet W is accommodated in the accommodation groove 12B, so that the light incident on the light detection section 32 from the outer circumferential side surface Wa of the tablet W can be transmitted by the circumferential wall 12D. It can be blocked. That is, the light irradiated onto the tablet W from the light irradiation section 31 can be efficiently transmitted through the tablet W. Furthermore, if the opening 12c is sufficiently small with respect to the tablet W, even if the measurement is performed as the accommodation groove 12B with no downward step, it is possible to prevent the light from mixing with stray light. Therefore, it is possible to prevent saturation from occurring in the light detection section 32 and to prevent the light passing through the tablet W from being mixed with stray light, so that the light detection section 32 can perform appropriate light analysis.

一方、周壁12Dの高さを高くすれば、錠剤Wの高さ方向で錠剤Wの外周側面Waを長い距離にわたって周壁12Dで覆うことできる。このため、錠剤Wの外周側面Waから光検出部32に入射する光を周壁12Dによってより効果的に遮ることができる。 On the other hand, if the height of the peripheral wall 12D is increased, the peripheral wall 12D can cover the outer peripheral side surface Wa of the tablet W over a long distance in the height direction of the tablet W. Therefore, the light that enters the light detection section 32 from the outer circumferential side surface Wa of the tablet W can be more effectively blocked by the peripheral wall 12D.

ところが、周壁12Dの高さを高くすると、錠剤Wが溝部12Aから収容溝12Bに移動に移動したときに、錠剤Wが開口部12cに斜めに落ち易く、錠剤Wが開口部12cに斜めに落ちると、物品検査部3によって正常な検査を行うことができない。 However, when the height of the peripheral wall 12D is increased, when the tablet W moves from the groove 12A to the accommodation groove 12B, the tablet W tends to fall diagonally into the opening 12c; In this case, the article inspection section 3 cannot perform a normal inspection.

本実施形態の物品検査装置1によれば、底壁12Cは、開口部12cの径方向内端部12sと径方向外端部12tとを連結し、開口部12cの一部を閉じる渡り板12gを有し、錠剤Wは、載置面12dと渡り板12gに載置された状態で収容溝12Bに収容される。 According to the article inspection device 1 of the present embodiment, the bottom wall 12C has a span plate 12g that connects the radially inner end 12s and the radially outer end 12t of the opening 12c and closes a part of the opening 12c. The tablet W is accommodated in the accommodation groove 12B while being placed on the placement surface 12d and the spanning plate 12g.

これにより、物品検査位置Pに対して外側搬送部12の回転方向の上流側において、錠剤Wが溝部12Aから収容溝12Bに移動したときに、錠剤Wの底面を渡り板12gに接触させながら開口部12cの径方向内端部12sから径方向外端部12tに向かって案内して収容溝12Bに案内できる。このため、錠剤Wが開口部12cに斜めに落ちることを防止でき、物品検査部3で適切な光の分析を行うことができる。 As a result, when the tablet W moves from the groove 12A to the storage groove 12B on the upstream side in the rotational direction of the outer conveyance section 12 with respect to the article inspection position P, the bottom surface of the tablet W is brought into contact with the connecting plate 12g while the opening is opened. It can be guided from the radially inner end 12s of 12c toward the radially outer end 12t and guided into the accommodation groove 12B. Therefore, the tablet W can be prevented from falling obliquely into the opening 12c, and the article inspection section 3 can perform appropriate light analysis.

このため、周壁12Dの高さを高くした場合でも、錠剤Wが開口部12cに斜めに落ちることを防止でき、物品検査部3で適切な光の分析をより確実に行うことができる。 Therefore, even when the height of the peripheral wall 12D is increased, the tablet W can be prevented from falling obliquely into the opening 12c, and the article inspection section 3 can more reliably perform an appropriate light analysis.

このように本実施形態の物品検査装置1は、迷光による影響を受けないように錠剤Wを物品検査位置P5に搬送することができ、錠剤Wを透過した光の分析を適切に行うことができる。 In this way, the article inspection device 1 of this embodiment can transport the tablet W to the article inspection position P5 without being affected by stray light, and can appropriately analyze the light that has passed through the tablet W. .

なお、錠剤Wを透過した光の分光特性に基づいて錠剤Wの品質を検査する物品検査装置1においては、錠剤Wの光が乱反射して均一化されるので、開口部12cの一部を渡り板12gで覆った場合でも、渡り板12gが検査に影響を与えることはない。 In addition, in the article inspection device 1 that inspects the quality of the tablet W based on the spectral characteristics of the light transmitted through the tablet W, since the light from the tablet W is diffusely reflected and becomes uniform, a part of the opening 12c is Even when covered with 12g, the 12g span plate will not affect the inspection.

なお、物品検査位置P5において、収容溝12Bと光検出部32の間に、光が透過する開口部39aを有する遮光板39を設置してもよい(遮光板39を図7の仮想線で示す)。このようにすれば遮光板39によって錠剤Wの外周側面Waから光検出部32に入射する光をより確実に遮ることができ、物品検査部3で適切な光の分析をよりより確実に行うことができる。 Note that at the article inspection position P5, a light shielding plate 39 having an opening 39a through which light passes may be installed between the accommodation groove 12B and the light detection unit 32 (the light shielding plate 39 is shown by the imaginary line in FIG. 7). ). In this way, the light shielding plate 39 can more reliably block the light that enters the light detection unit 32 from the outer circumferential side surface Wa of the tablet W, and the article inspection unit 3 can more reliably perform an appropriate light analysis. I can do it.

また、本実施形態の収容溝12Bは、溝部12Aの底面12bよりも下方に窪む載置面12dを有するが、載置面12dと底面12bを同じ高さにしてもよい。収容溝12Bは、光が通過する開口部12cが形成され、錠剤Wが載置される載置面12dを有する底壁12Cと、錠剤Wの外周側面Waを取り囲む周壁12Dとを備えていれば、底壁12Cと周壁12Dによって錠剤Wを囲むことができる。 Moreover, although the accommodation groove 12B of this embodiment has 12 d of mounting surfaces recessed below the bottom surface 12b of 12 A of groove parts, 12 d of mounting surfaces and the bottom surface 12b may be the same height. If the storage groove 12B is provided with a bottom wall 12C having an opening 12c through which light passes and a placement surface 12d on which the tablet W is placed, and a peripheral wall 12D surrounding the outer circumferential side surface Wa of the tablet W. , the tablet W can be surrounded by the bottom wall 12C and the peripheral wall 12D.

このように構成することにより、物品検査装置1は、光検出部32でサチュレーションが生じることや、錠剤Wを通過した光が迷光と混じることを防止でき、光検出部32で適切な光の分析を行うことができる。 With this configuration, the article inspection device 1 can prevent saturation in the light detection section 32 and prevent light passing through the tablet W from being mixed with stray light, and can prevent the light detection section 32 from appropriately analyzing light. It can be performed.

また、本実施形態の物品検査装置1は、載置補助部を渡り板12gから構成しているが、これに限るものではなく、梯子形状でもよい。 Further, in the article inspection device 1 of this embodiment, the placement auxiliary portion is composed of the spanning board 12g, but is not limited to this, and may have a ladder shape.

また、渡り板12gは、延在方向の中央部が下方に湾曲した形状であってもよい。このようにすれば、延在方向の中央部が上方に湾曲した形状である場合に比べて、錠剤Wを収容溝12Bに円滑に収容できる。 Further, the connecting plate 12g may have a shape in which the central portion in the extending direction is curved downward. In this way, the tablet W can be accommodated in the accommodation groove 12B more smoothly than in the case where the central portion in the extending direction is curved upward.

また、本実施形態の物品検査装置1によれば、渡り板12gは、外側搬送部12の回転方向の両側に開口部12cが形成されるように、開口部12cの上方を通過して開口部12cの径方向内端部12sと径方向外端部12tとを連結している。 Further, according to the article inspection device 1 of the present embodiment, the spanning plate 12g passes above the opening 12c and passes through the opening 12c so that the opening 12c is formed on both sides of the outer conveyance section 12 in the rotational direction. A radial inner end 12s and a radial outer end 12t are connected to each other.

これにより、錠剤Wの先端部Wuを渡り板12gに接触させ易く、錠剤Wの先端部Wuが開口部12cに落ちて渡り板12gに引っ掛かることや、開口部12cに斜めに落ちることをより効果的に防止できる。 This makes it easier to bring the tip Wu of the tablet W into contact with the spanning plate 12g, and more effectively prevents the tip Wu of the tablet W from falling into the opening 12c and getting caught on the spanning plate 12g, or falling diagonally into the opening 12c. It can be prevented.

また、本実施形態の物品検査装置1によれば、外側搬送部12は、収容溝12Bに対して外側搬送部12の径方向内方に設けられ、錠剤Wを収容溝12Bに案内する溝部12Aを有する。溝部12Aは、外側搬送部12の径方向内方から径方向外方に延在し、外側搬送部12の回転時に錠剤Wの外周側面Waが接触可能な側壁12Eを有し、渡り板12gは、側壁12Eの延在方向と平行に延在している。 Further, according to the article inspection device 1 of the present embodiment, the outer conveyance section 12 is provided radially inward of the outer conveyance section 12 with respect to the accommodation groove 12B, and the groove section 12A guides the tablet W to the accommodation groove 12B. has. The groove portion 12A extends from the inside in the radial direction to the outside in the radial direction of the outer conveyance portion 12, and has a side wall 12E that can be contacted by the outer circumferential side surface Wa of the tablet W when the outer conveyance portion 12 rotates. It extends parallel to the extending direction of the side wall 12E.

これにより、錠剤Wの先端部Wuを渡り板12gに接触させ易く、錠剤Wの先端部Wuが開口部12cに落ちて渡り板12gに引っ掛かることや、開口部12cに斜めに落ちることをより効果的に防止できる。 This makes it easier to bring the tip Wu of the tablet W into contact with the spanning plate 12g, and more effectively prevents the tip Wu of the tablet W from falling into the opening 12c and getting caught on the spanning plate 12g, or falling diagonally into the opening 12c. It can be prevented.

なお、本実施形態の物品検査装置1は、外側搬送部12の径方向内方に溝部12Aが形成され、溝部12Aに対して外側搬送部12の径方向外方に収容溝12Bが形成されているが、これに限定されるものではない。 In addition, in the article inspection device 1 of the present embodiment, a groove 12A is formed radially inward of the outer conveyance section 12, and an accommodation groove 12B is formed radially outward of the outer conveyance section 12 with respect to the groove 12A. However, it is not limited to this.

例えば、外側搬送部12の径方向外方に溝部12Aが形成され、溝部12Aに対して外側搬送部12の径方向内方に収容溝12Bが形成されてもよい。この場合には外側搬送部12の径方向外方から外側搬送部12の溝部12Aに錠剤を供給し、溝部12Aに沿って外側搬送部12の径方向内方に錠剤Wを移動させ、収容溝12Bに錠剤Wを収容すればよい。 For example, the groove portion 12A may be formed radially outward of the outer conveyance portion 12, and the accommodation groove 12B may be formed radially inward of the outer conveyance portion 12 with respect to the groove portion 12A. In this case, the tablets are supplied from the outside in the radial direction of the outer transport part 12 to the groove 12A of the outer transport part 12, and the tablet W is moved radially inward of the outer transport part 12 along the groove 12A, and then Tablets W may be stored in 12B.
