Description

散薬分配装置及び軸受カバーPowder distribution device and bearing cover
本発明は、散薬分配装置及び軸受カバーに関するものである。 The present invention relates to a powder distribution device and a bearing cover.
従来、散薬分配装置として、ドーナツ状で、断面円弧状の窪みである環状溝を備えた散薬分配皿を所定のピッチ角度で回転させ、環状溝に堆積した散薬を掻出装置により１包分ずつ掻き出し可能としたものがある（例えば、特許文献１、２参照）。 Conventionally, as a powder distribution device, a powder distribution plate provided with an annular groove that is a donut-shaped depression having an arcuate cross section is rotated at a predetermined pitch angle, and the powder accumulated in the annular groove is dispensed one by one by a scraping device. There are some which can be scraped (see, for example, Patent Documents 1 and 2).
前記散薬分配装置では、散薬分配皿に供給された散薬を内側に掻き出すことにより、装置の小型化を可能としている。このため、散薬分配皿は、その一部から延在させた支持リングの内周縁を軸受ローラによって回転可能に支持した構成が採用されている。 In the powder distribution device, the powder can be reduced in size by scraping the powder supplied to the powder distribution tray inward. For this reason, the powder distribution tray has a configuration in which the inner peripheral edge of the support ring extended from a part thereof is rotatably supported by the bearing roller.
しかしながら、前記従来の散薬分配装置では、散薬を掻き出す際、この散薬が飛散して軸受ローラに付着することがある。軸受ローラに付着した散薬は、支持リングとの間で異音を発生させたり、支持リングすなわち散薬分配皿のスムーズな回転を妨げたりする原因となる恐れがある。 However, in the conventional powder distribution device, when the powder is scraped, the powder may scatter and adhere to the bearing roller. The powder adhering to the bearing roller may cause abnormal noise with the support ring, and may cause the support ring, that is, the powder distribution tray to be prevented from rotating smoothly.
また、支持リングの外周縁を軸受ローラによって回転可能に支持する場合であっても、散薬を掻き出す際、特に外周側に掻き出す際、同様に、飛散した散薬が軸受ローラに付着する恐れがある。 Further, even when the outer peripheral edge of the support ring is rotatably supported by the bearing roller, the scattered powder may adhere to the bearing roller when the powder is scraped, particularly when the powder is scraped to the outer peripheral side.

本発明は、ドーナツ状の散薬分配皿から散薬を掻き出す構成であっても、飛散した散薬が軸受ローラに付着することによって不具合を発生させることのない散薬分配装置及び軸受カバーを提供することを課題とする。 It is an object of the present invention to provide a powder distribution device and a bearing cover that do not cause a malfunction due to the scattered powder adhering to the bearing roller even if the powder is scraped from the donut-shaped powder distribution tray. And
本発明は、前記課題を解決するための手段として、断面円弧状の環状溝を備えたドーナツ状の散薬分配皿を所定のピッチ角度で回転し、掻出装置により前記環状溝に供給した散薬を１包分ずつ掻き出し可能とする散薬分配装置であって、前記散薬分配皿に形成され、内縁部又は外縁部を有する支持リングを備え、前記支持リングの内縁部又は外縁部をガイドするガイド溝を有し、前記散薬分配皿を回転可能に支持する軸受ローラと、前記軸受ローラに着脱可能で、少なくともガイド溝から上方部分を覆う軸受カバーと、をさらに備えたものである。 As a means for solving the above-mentioned problems, the present invention rotates a doughnut-shaped powder distribution tray provided with an annular groove having an arc-shaped cross section at a predetermined pitch angle, and supplies the powder supplied to the annular groove by a scraping device. A powder distribution device capable of scraping one package at a time, comprising a support ring formed on the powder distribution plate and having an inner edge or an outer edge, and a guide groove for guiding the inner edge or the outer edge of the support ring. And a bearing roller that rotatably supports the powder distribution tray, and a bearing cover that is attachable to and detachable from the bearing roller and covers at least an upper portion from the guide groove.
この構成により、たとえ散薬が飛散したとしても、軸受カバーによって飛散した散薬が軸受ローラに至ることを防止することができる。したがって、軸受ローラに散薬が付着して、異音の発生原因となったり、場合によっては散薬分配皿の回転動作に支障を来したりするといった不具合の発生を防止することができる。 With this configuration, even if the powder is scattered, the powder scattered by the bearing cover can be prevented from reaching the bearing roller. Therefore, it is possible to prevent the occurrence of problems such as powder adhering to the bearing roller, causing abnormal noise, and possibly hindering the rotational operation of the powder distribution tray.
前記軸受カバーは、前記支持リングの内縁部に摺接する清掃部材を備えるのが好ましい。 It is preferable that the bearing cover includes a cleaning member that is in sliding contact with an inner edge portion of the support ring.
この構成により、たとえ軸受カバー以外の位置で、支持リングの内縁部又は外縁部に散薬が付着したとしても、清掃部材によって除去することができる。したがって、軸受ローラに付着した散薬が至ることがない。 With this configuration, even if the powder adheres to the inner edge or the outer edge of the support ring at a position other than the bearing cover, it can be removed by the cleaning member. Therefore, the powder adhering to the bearing roller does not reach.
前記軸受ローラのガイド溝に摺接する第２の清掃部材を備えるのが好ましい。 It is preferable to provide a second cleaning member that is in sliding contact with the guide groove of the bearing roller.
この構成により、たとえ清掃部材によって支持リングの内縁部又は外縁部に付着した散薬を除去し切れずに、軸受ローラのガイド溝に散薬が至った場合であっても、第２の清掃部材によってこれを除去することができる。 With this configuration, even if the powder reaches the guide groove of the bearing roller without completely removing the powder adhering to the inner edge or the outer edge of the support ring by the cleaning member, the second cleaning member Can be removed.
前記第２の清掃部材は、前記軸受カバーに設けるようにすればよい。 The second cleaning member may be provided on the bearing cover.
前記軸受カバーは、前記軸受ローラの上面を覆う上面部と、前記軸受ローラの外周面のうち、支持リングのガイドに際して邪魔にならない位置を覆う側面部とを備え、前記支持リングの内縁部又は外縁部に摺接する清掃部材は、側面部の両端にそれぞれ設けるようにすればよい。 The bearing cover includes an upper surface portion that covers an upper surface of the bearing roller, and a side surface portion that covers a position that does not interfere with the guide of the support ring, of the outer peripheral surface of the bearing roller, and an inner edge portion or an outer edge of the support ring The cleaning member slidably contacting the part may be provided at both ends of the side part.
なお、軸受ローラの外周面のうち、支持リングのガイドに際して邪魔にならない位置とは、少なくとも軸受ローラにより支持リングを回転可能に支持可能な領域を除く意味であり、できるだけ広い範囲で軸受ローラの外周面を覆うことができる位置であるのが好ましい。 In the outer peripheral surface of the bearing roller, the position that does not interfere with the guide of the support ring means that at least the region where the support ring can be rotatably supported by the bearing roller is excluded, and the outer periphery of the bearing roller is as wide as possible. A position where the surface can be covered is preferable.
また、前記第２の清掃部材は、側面部の内面に形成すればよい。 Moreover, what is necessary is just to form the said 2nd cleaning member in the inner surface of a side part.
前記清掃部材は、軸受カバーに着脱可能であるのが好ましい。 The cleaning member is preferably detachable from the bearing cover.
この構成により、最も摩耗しやすいと考えられる清掃部材のみを交換することができ、長期に亘って使用することが可能となる。 With this configuration, it is possible to replace only the cleaning member that is considered to be most easily worn, and it can be used for a long period of time.
前記軸受カバーは、散薬分配皿の下方で内周縁部又は外周縁部に沿って配置される散薬侵入防止壁を備えるのが好ましい。 It is preferable that the bearing cover includes a powder intrusion prevention wall disposed along the inner peripheral edge or the outer peripheral edge below the powder distribution tray.
この構成により、より一層、飛散した散薬が軸受ローラに至ることを防止することが可能となる。 With this configuration, it is possible to further prevent the scattered powder from reaching the bearing roller.
前記軸受カバーは、外面に係止受部を備え、前記軸受ローラの近傍には、前記軸受カバーの装着時、前記係止受部が係止されることにより装着状態を構成する係止部を設けるのが好ましい。 The bearing cover includes a locking receiving portion on an outer surface, and a locking portion that forms a mounting state by locking the locking receiving portion when the bearing cover is mounted in the vicinity of the bearing roller. It is preferable to provide it.
この構成により、軸受カバーの装着状態で、軸受ローラの回転が軸受カバーから抵抗を受けにくくなり、散薬分配皿のスムーズな回転を確保することが可能となる。 With this configuration, when the bearing cover is mounted, the rotation of the bearing roller is less likely to receive resistance from the bearing cover, and it is possible to ensure smooth rotation of the powder distribution tray.
前記支持リングの内縁部又は外縁部に摺接する清掃部材は、先端がＶ字状に切り欠かれることにより、上方側傾斜面と下方側傾斜面とを形成され、各傾斜面は、両側から徐々に幅が狭くなるように形成されているのが好ましい。 The cleaning member that is in sliding contact with the inner edge portion or the outer edge portion of the support ring is formed with an upper inclined surface and a lower inclined surface by cutting the tip into a V shape, and each inclined surface is gradually formed from both sides. It is preferable that the width is narrow.
この構成により、支持リングの内縁部又は外縁部に対して清掃部材を適切に摺接させることができる。すなわち、各傾斜面は、両側から徐々に幅が狭くなるように形成されているので、多少変形しても、支持リングの内縁部又は外縁部への過度の干渉が回避される。また、支持リングの内縁部に接触するのは、幅の狭くなった中央部分のみであるので、接触抵抗が小さい。したがって、散薬分配皿の回転が妨げられたり、清掃部材が損傷したりといった不具合の発生を防止することができる。 With this configuration, the cleaning member can be appropriately brought into sliding contact with the inner edge portion or the outer edge portion of the support ring. That is, since each inclined surface is formed so that the width is gradually narrowed from both sides, excessive interference with the inner edge portion or the outer edge portion of the support ring is avoided even if the inclined surface is slightly deformed. Further, since only the central portion having a narrow width contacts the inner edge of the support ring, the contact resistance is small. Therefore, it is possible to prevent the occurrence of problems such as the rotation of the powder distribution tray being hindered or the cleaning member being damaged.
前記支持リングの内縁部又は外縁部は、断面矩形状であるのが好ましい。 The inner edge or outer edge of the support ring preferably has a rectangular cross section.
この構成により、清掃部材の各傾斜面への接触面積を大幅に抑制することができるので、たとえ散薬が付着したとしても、影響が少なく、散薬分配皿をスムーズに回転させることができる。 With this configuration, the contact area of the cleaning member with each inclined surface can be significantly reduced, so even if the powder adheres, there is little influence and the powder distribution tray can be rotated smoothly.
前記支持リングは、前記散薬分配皿から外径方向に延びる外縁部又は内径方向に延びる内縁部で構成し、前記外縁部又は前記内縁部を、前記軸受ローラによって回転可能に支持するようにしてもよい。 The support ring is configured by an outer edge portion extending in an outer diameter direction or an inner edge portion extending in an inner diameter direction from the powder distribution tray, and the outer edge portion or the inner edge portion is rotatably supported by the bearing roller. Good.
また、本発明は、前記課題を解決するための手段として、断面円弧状の環状溝を備えたドーナツ状の散薬分配皿を所定のピッチ角度で回転し、掻出装置により前記環状溝に供給した散薬を１包分ずつ掻き出し可能とする散薬分配装置に使用される軸受カバーであって、前記散薬分配皿は、底面側に一体的に形成され、内縁部又は外縁部を有する支持リングを備え、前記支持リングの内縁部又は外縁部をガイドするガイド溝を有し、前記散薬分配皿を回転可能に支持する軸受ローラに着脱可能で、少なくともガイド溝から上方部分を覆うようにしたものである。 Further, in the present invention, as a means for solving the above-mentioned problem, a donut-shaped powder distribution tray provided with an annular groove having an arc-shaped cross section is rotated at a predetermined pitch angle and supplied to the annular groove by a scraping device. A bearing cover used for a powder distribution device that can scrape out powder one by one, wherein the powder distribution tray is integrally formed on the bottom surface side, and includes a support ring having an inner edge or an outer edge, The guide ring has a guide groove that guides the inner edge or the outer edge of the support ring, is detachable from a bearing roller that rotatably supports the powder distribution tray, and covers at least the upper part from the guide groove.
本発明によれば、軸受ローラを軸受カバーで覆うようにしたので、飛散した散薬が軸受ローラに至って、異音の発生や散薬分配皿の回転不良をもたらすことがない。 According to the present invention, since the bearing roller is covered with the bearing cover, the scattered powder does not reach the bearing roller, and no abnormal noise is generated and the powder distribution tray does not rotate properly.

以下、本発明に係る実施形態を添付図面に従って説明する。なお、以下の説明では、必要に応じて特定の方向や位置を示す用語（例えば、「上」、「下」、「側」、「端」含む用語）を用いるが、それらの用語の使用は図面を参照した発明の理解を容易にするためであって、それらの用語の意味によって本発明の技術的範囲が限定されるものではない。また、以下の説明は、本質的に例示に過ぎず、本発明、その適用物或いはその用途を制限することを意図するものではない。 Embodiments according to the present invention will be described below with reference to the accompanying drawings. In the following description, terms indicating specific directions and positions (for example, terms including “up”, “down”, “side”, “end”) are used as necessary. In order to facilitate understanding of the invention with reference to the drawings, the technical scope of the present invention is not limited by the meaning of these terms. Further, the following description is merely illustrative in nature, and is not intended to limit the present invention, its application, or its use.
図１は本発明の散薬分配装置を示す。この散薬分配装置では、支持プレート１に散薬分配皿２が回転可能に支持されている。 FIG. 1 shows a powder dispensing device of the present invention. In this powder distribution device, the powder distribution tray 2 is rotatably supported by the support plate 1.
散薬分配皿２は、金属製の薄板をドーナツ状にプレス加工し、その上面に断面円弧状の環状溝３を形成したものである。散薬分配皿２の下面には、支持リング４が一体化されている。支持リング４は、内周側に突出する内縁部４ａを有する。内縁部は、先端に向かうに従って厚さ方向の中央に向かって徐々に薄くなる断面三角形状に形成されている。支持リング４の内縁部は、支持プレート１に回転可能に３箇所等分で取り付けた軸受ローラ５によって回転可能に支持されている。また、図示しないが、支持リング４の外縁部には従動ギアが形成され、モータの回転軸に設けた駆動ギアが噛合し、モータの駆動力により散薬分配皿２が回転するようになっている。なお、支持リング４は散薬分配皿２の下面に形成されているので、散薬が進入しにくい。 The powder distribution tray 2 is obtained by pressing a metal thin plate into a donut shape and forming an annular groove 3 having a circular arc cross section on the upper surface thereof. A support ring 4 is integrated with the lower surface of the powder distribution tray 2. The support ring 4 has an inner edge portion 4a that protrudes toward the inner peripheral side. The inner edge is formed in a triangular cross section that gradually decreases toward the center in the thickness direction toward the tip. The inner edge portion of the support ring 4 is rotatably supported by a bearing roller 5 that is rotatably attached to the support plate 1 at three equal portions. Although not shown, a driven gear is formed on the outer edge portion of the support ring 4, and a drive gear provided on the rotating shaft of the motor is engaged, so that the powder distribution tray 2 is rotated by the driving force of the motor. . In addition, since the support ring 4 is formed in the lower surface of the powder distribution tray 2, it is difficult for powder to enter.
軸受ローラ５は、円筒状で、その外周面には、全周に亘って、内縁部の上下傾斜面に当接する略Ｖ字形のガイド溝６が形成されている。 The bearing roller 5 has a cylindrical shape, and a substantially V-shaped guide groove 6 is formed on the outer peripheral surface of the bearing roller 5 so as to be in contact with the vertically inclined surface of the inner edge portion.
各軸受ローラ５は軸受カバー７によって覆われている。軸受カバー７は、図２～４に示すように、平面視略半円状の上面部８と、この上面部８の前縁を除く外縁に沿って形成される側面部９とを備え、合成樹脂材料を成形加工することにより得られる。軸受カバー７は、軸受ローラ５の上半部（ガイド溝６によって分離された上方側の部位）に装着される。そして、この装着状態で、上面部８は軸受ローラ５の上面部分を覆い、側面部９は軸受ローラ５の外周面を覆う。これにより、飛散した散薬等の軸受ローラ５への付着が防止される。 Each bearing roller 5 is covered with a bearing cover 7. As shown in FIGS. 2 to 4, the bearing cover 7 includes an upper surface portion 8 having a substantially semicircular shape in plan view, and a side surface portion 9 formed along the outer edge excluding the front edge of the upper surface portion 8. It is obtained by molding a resin material. The bearing cover 7 is attached to the upper half of the bearing roller 5 (an upper part separated by the guide groove 6). In this mounted state, the upper surface portion 8 covers the upper surface portion of the bearing roller 5, and the side surface portion 9 covers the outer peripheral surface of the bearing roller 5. Thereby, adhesion of the scattered powder etc. to the bearing roller 5 is prevented.
側面部９の両端部（前端側の端部）には、上面部８の前端から突出する突出部９ａが形成されている。突出部９ａには第１清掃片１０が設けられている。また、側面部９の内周面中央部には第２清掃片１１が設けられている。各清掃片は、ウレタンゴム等の可撓性を有する材料からなる。第１清掃片１０の上下傾斜面１０ａ、１０ｂは、支持リング４の内縁部４ａの上下傾斜面に摺接し、支持リング４の内縁部に付着した散薬等を除去する。ここでは、各清掃片１０、１１は接着剤等により側面部９に固定されている。 Protruding portions 9 a that protrude from the front end of the upper surface portion 8 are formed at both end portions (the end portion on the front end side) of the side surface portion 9. A first cleaning piece 10 is provided on the protruding portion 9a. In addition, a second cleaning piece 11 is provided in the central portion of the inner peripheral surface of the side surface portion 9. Each cleaning piece is made of a flexible material such as urethane rubber. The upper and lower inclined surfaces 10 a and 10 b of the first cleaning piece 10 are in sliding contact with the upper and lower inclined surfaces of the inner edge portion 4 a of the support ring 4, and remove powders and the like attached to the inner edge portion of the support ring 4. Here, the cleaning pieces 10 and 11 are fixed to the side surface portion 9 with an adhesive or the like.
第１清掃片１０の先端はＶ字状に切り欠かれることにより、上方側傾斜面１０ａと、下方側傾斜面１０ｂとが形成されている。これら傾斜面１０ａ、１０ｂは、両側から徐々に幅が狭くなることにより、中央部傾斜面１０ａ―１、１０ｂ－１と、前方側傾斜面１０ａ－２、１０ｂ－２と、後方側傾斜面１０ａ－３、１０ｂ－３とが形成されている。前方側傾斜面１０ａ－２、１０ｂ－２は、支持リング４の内縁部４ａの移動方向に対して上流側に位置する。前方側傾斜面１０ａ－２、１０ｂ－２の存在により、第１清掃片１０が変形したとしても、支持リング４の内縁部４ａとの接触状態が悪化して散薬分配皿２の回転不良を引き起こしたり、場合によっては損傷したりするといった不具合の発生を防止する。また、後方側傾斜面１０ａ－３、１０ｂ－３の存在により、中央部傾斜面１０ａ―１、１０ｂ－１の支持リング４の内縁部４ａとの接触面積を小さくして、散薬分配皿２の回転抵抗を抑制することができる。第２清掃片１１の先端は三角形状に形成され、軸受ローラ５のガイド溝６の上下傾斜面に摺接し、軸受ローラ５のガイド溝６に付着した散薬等を除去する。 The tip of the first cleaning piece 10 is cut into a V shape, thereby forming an upper inclined surface 10a and a lower inclined surface 10b. The inclined surfaces 10a and 10b are gradually narrowed from both sides, whereby the central inclined surfaces 10a-1 and 10b-1, the front inclined surfaces 10a-2 and 10b-2, and the rear inclined surface 10a. -3, 10b-3. The front inclined surfaces 10 a-2 and 10 b-2 are located on the upstream side with respect to the moving direction of the inner edge portion 4 a of the support ring 4. Even if the first cleaning piece 10 is deformed due to the presence of the front inclined surfaces 10a-2 and 10b-2, the contact state with the inner edge portion 4a of the support ring 4 is deteriorated, causing rotation failure of the powder distribution tray 2. Or troubles such as damage in some cases. Further, due to the presence of the rear inclined surfaces 10a-3 and 10b-3, the contact area of the central inclined surfaces 10a-1 and 10b-1 with the inner edge portion 4a of the support ring 4 is reduced, so that the powder distribution tray 2 Rotational resistance can be suppressed. The tip of the second cleaning piece 11 is formed in a triangular shape, slidably contacts the upper and lower inclined surfaces of the guide groove 6 of the bearing roller 5, and removes the powder adhering to the guide groove 6 of the bearing roller 5.
なお、第１清掃片１０を側面部９の両端部に設けたのは、散薬分配皿２の回転方向を考慮したものである。すなわち、散薬分配皿２から散薬を掻き出す場合、散薬分配皿２を図９（ａ）に示す矢印方向に回転させるので、図中、右側の第１清掃片１０によって散薬が除去される。また、散薬分配皿２に散薬を供給する場合、散薬の供給方向は、図９（ａ）又は（ｂ）の矢印で示す散薬掻出装置２の移動方向とは逆方向から斜め下方に向かわせるようにしている。図９（ａ）の矢印で示す場合は、散薬を掻き出す場合と同様に、図中、右側の第１清掃片１０によって散薬が除去され、図９（ｂ）で示す場合は、図中、左側の第１清掃片１０によって散薬が除去される。これにより、複数の散薬フィーダ（図示せず）から散薬分配皿２に散薬を供給する場合（異種の散薬を供給する場合及び同種の散薬を供給する場合のいずれも含む）であっても、第１清掃片１０により支持リング４の内縁部４ａに付着した散薬を除去して、軸受ローラ５への散薬の付着を効果的に防止することができる。 In addition, the 1st cleaning piece 10 was provided in the both ends of the side part 9 in consideration of the rotation direction of the powder distribution tray 2. That is, when scraping the powder from the powder distribution tray 2, the powder distribution tray 2 is rotated in the direction of the arrow shown in FIG. 9A, so that the powder is removed by the first cleaning piece 10 on the right side in the figure. Moreover, when supplying a powder to the powder distribution tray 2, the powder supply direction is directed obliquely downward from a direction opposite to the moving direction of the powder scraping device 2 indicated by an arrow in FIG. 9 (a) or (b). I am doing so. In the case shown by the arrow in FIG. 9A, the powder is removed by the first cleaning piece 10 on the right side in the figure, as in the case of scraping out the powder, and in the case shown in FIG. 9B, the left side in the figure The powder is removed by the first cleaning piece 10. Thereby, even when supplying powder to the powder distribution tray 2 from a plurality of powder feeders (not shown) (including when supplying different types of powder and supplying the same type of powder) By removing the powder adhering to the inner edge 4 a of the support ring 4 by the one cleaning piece 10, it is possible to effectively prevent the powder from adhering to the bearing roller 5.
前記構成の軸受カバー７は、軸受ローラ５の上半部を覆うようにして装着される。ここでは、軸受カバー７を装着するための構成については特に記載しないが、軸受ローラ５の回転を妨げないのであれば、いずれの構成でも採用することができる（例えば、後述する図８に示す構成等）。そして、装着状態では、軸受カバー７の各清掃片１０、１１が支持リング４の内縁部４ａ、軸受ローラ５がガイド溝６にそれぞれ圧接する。 The bearing cover 7 having the above-described configuration is mounted so as to cover the upper half of the bearing roller 5. Here, the configuration for mounting the bearing cover 7 is not particularly described, but any configuration can be adopted as long as the rotation of the bearing roller 5 is not hindered (for example, the configuration shown in FIG. 8 described later). etc). In the mounted state, the cleaning pieces 10 and 11 of the bearing cover 7 are in pressure contact with the inner edge portion 4a of the support ring 4 and the bearing roller 5 is in pressure contact with the guide groove 6, respectively.
環状溝３には、図示しない投入ホッパーから散薬を供給する。すなわち、モータを駆動して散薬分配皿２を一定速度で回転させながら、投入ホッパーから環状溝３内に、単位時間当たり一定量の散薬を供給する。これにより、環状溝３内には散薬が均一に供給される。 Powder is supplied to the annular groove 3 from a charging hopper (not shown). That is, a constant amount of powder is supplied per unit time from the charging hopper into the annular groove 3 while driving the motor to rotate the powder distribution tray 2 at a constant speed. Thereby, the powder medicine is uniformly supplied into the annular groove 3.
環状溝３に供給された散薬は、図１に示すように、掻出装置１２によって１包分ずつ掻き出され、図示しない包装ユニットにて包装される。掻出装置１２は、回転駆動可能に設けた支持台１３に、回動可能にアーム部材１４を設け、その先端に掻出片１５を有する掻寄板１６を取り付けた構成である（掻出装置１２の詳細については、例えば、特許第４０５７１５９号公報参照のこと）。 As shown in FIG. 1, the powder supplied to the annular groove 3 is scraped one by one by the scraping device 12 and packaged by a packaging unit (not shown). The scraping device 12 has a configuration in which an arm member 14 is rotatably provided on a support base 13 provided so as to be rotatable and a scraping plate 16 having a scraping piece 15 is attached to the tip thereof (the scraping device). (For example, refer to Japanese Patent No. 4057159).
前記散薬分配皿２の環状溝３は、清掃装置１７によって清掃される。清掃装置１７は、回転駆動可能なローラブラシ１８と、このローラブラシ１８を覆うガイドカバー１９と、ガイドカバー１９内から飛散した散薬を吸引する吸引ポンプ２０とを備える（清掃装置１７の詳細については、例えば、特開２００７－５５６８９号公報を参照のこと）。 The annular groove 3 of the powder distribution tray 2 is cleaned by a cleaning device 17. The cleaning device 17 includes a roller brush 18 that can be rotationally driven, a guide cover 19 that covers the roller brush 18, and a suction pump 20 that sucks the powder scattered from the guide cover 19 (for details of the cleaning device 17). (For example, see JP-A-2007-55689).
前記構成からなる散薬分配装置では、散薬分配皿２を円周方向に所定ピッチ回転させ、掻出装置１２を駆動することにより、環状溝３から内側に向かって１包分の散薬を掻き出す。この場合、掻き出した散薬の一部が飛散することがある。飛散した散薬は、支持プレート１に至り、軸受ローラ５にも向かう。軸受ローラ５には軸受カバー７が装着されている。したがって、飛散した散薬が軸受ローラ５に付着することはない。 In the powder distribution device having the above-described configuration, the powder distribution plate 2 is rotated by a predetermined pitch in the circumferential direction and the scraping device 12 is driven to scrape one powder of powder from the annular groove 3 toward the inside. In this case, a part of the scraped powder may be scattered. The scattered powder reaches the support plate 1 and travels toward the bearing roller 5. A bearing cover 7 is attached to the bearing roller 5. Therefore, the scattered powder does not adhere to the bearing roller 5.
また、飛散した散薬は、支持リング４の内縁部にも付着する恐れがある。支持リング４の内縁部にした散薬は、散薬分配皿２が回転する際、軸受カバー７に設けた第１清掃片１０によって掻き落とされる。したがって、付着した散薬が軸受ローラ５のガイド溝６に至ることがない。万一、第１清掃片１０によって除去し切れずに軸受ローラ５のガイド溝６に至った散薬は、第２清掃片１１によって掻き落とされる。 In addition, the scattered powder may adhere to the inner edge of the support ring 4. The powder on the inner edge of the support ring 4 is scraped off by the first cleaning piece 10 provided on the bearing cover 7 when the powder distribution tray 2 rotates. Therefore, the adhering powder does not reach the guide groove 6 of the bearing roller 5. In the unlikely event that the first cleaning piece 10 is not completely removed, the powder that reaches the guide groove 6 of the bearing roller 5 is scraped off by the second cleaning piece 11.
このように、軸受ローラ５に軸受カバー７を装着することにより、まず、飛散した散薬が軸受ローラ５に付着することを防止することができる。しかも、支持リング４の内縁部に付着したとしても、第１清掃片１０、さらには第２清掃片１１によって完全に除去される。したがって、従来問題となっていた、異音や回転不具合の発生を確実に防止することができる。 Thus, by attaching the bearing cover 7 to the bearing roller 5, it is possible to first prevent the scattered powder from adhering to the bearing roller 5. Moreover, even if it adheres to the inner edge of the support ring 4, it is completely removed by the first cleaning piece 10 and further by the second cleaning piece 11. Therefore, it is possible to reliably prevent the occurrence of abnormal noise and rotation problems, which have been problems in the past.
なお、本発明は、前記実施形態に記載された構成に限定されるものではなく、種々の変更が可能である。 In addition, this invention is not limited to the structure described in the said embodiment, A various change is possible.
前記実施形態では、図５（ａ）に示すように、支持リング４の内縁部４ａを断面三角形状に形成したが、図５（ｂ）に示すように、断面矩形状としてもよい。この場合、支持プレート１の内縁部４ａの上下角部が軸受ローラ５のガイド溝６を構成する上下傾斜面に線接触することになる。これによれば、支持リング４と軸受ローラ５との間の接触面積を抑制して付着した散薬の影響を受けにくくすることが可能となる点で好ましい。但し、接触部分を面取りすることによりガイド状態を安定させることも可能である。 In the embodiment, as shown in FIG. 5A, the inner edge 4a of the support ring 4 is formed in a triangular cross section, but as shown in FIG. 5B, a rectangular cross section may be used. In this case, the upper and lower corners of the inner edge 4 a of the support plate 1 are in line contact with the upper and lower inclined surfaces constituting the guide groove 6 of the bearing roller 5. This is preferable in that the contact area between the support ring 4 and the bearing roller 5 can be suppressed to make it less susceptible to the adhering powder. However, the guide state can be stabilized by chamfering the contact portion.
前記実施形態では、支持リング４の内縁部４ａ及び軸受ローラ５のガイド溝６の清掃に清掃片１０、１１を使用したが、これに代えてブラシ等の他の形態の清掃部材で構成してもよい。要は、付着した散薬を除去可能な構成であればよい。 In the said embodiment, although the cleaning pieces 10 and 11 were used for cleaning of the inner edge part 4a of the support ring 4 and the guide groove 6 of the bearing roller 5, it replaced with this and comprised by the cleaning members of other forms, such as a brush. Also good. In short, any configuration capable of removing the adhering powder is sufficient.
前記実施形態では、軸受カバー７を図２～４に示す構成としたが、図６に示すように、上面部８に散薬侵入防止壁２１を備えた構成としてもよい。すなわち、軸受カバー７には、軸受ローラ５に装着した状態で、散薬分配皿２の内周縁部の下面に沿う円弧状の散薬侵入防止壁２１が形成されている。これにより、散薬が散薬分配皿２の下方側に侵入し、軸受ローラ５に至ることを防止することができる。したがって、前述の構成とも相俟って、より一層、異音や回転不具合の発生を確実に防止することが可能となる。 In the above embodiment, the bearing cover 7 is configured as shown in FIGS. 2 to 4, but as shown in FIG. 6, the upper surface portion 8 may be provided with a powder intrusion prevention wall 21. That is, the bearing cover 7 is formed with an arc-shaped powder intrusion prevention wall 21 along the lower surface of the inner peripheral edge of the powder distribution tray 2 in a state of being mounted on the bearing roller 5. Thereby, it is possible to prevent the powder from entering the lower side of the powder distribution tray 2 and reaching the bearing roller 5. Therefore, in combination with the above-described configuration, it is possible to further reliably prevent the generation of abnormal noise and rotation failure.
前記実施形態では、軸受カバー７に接着剤等により清掃片１０、１１を取り付けるようにしたが、図７に示すように、清掃片１０、１１を着脱可能な構成としてもよい。すなわち、軸受カバー７の側面部９に設けた突出部９ａに断面略半円状の係合溝９ｂを形成する。係合溝９ｂは、先端に向かって徐々に広がるように形成されている。一方、清掃片（ここでは、第１清掃片１０のみ図示）の後端側には係合溝９ｂに着脱可能な略半円柱状の取付部１０ｃを形成する。そして、図７（ａ）の矢印で示すようにして係合溝９ｂに取付部１０ｃを圧入することにより装着する。このようにして清掃片１０（又は１１）を取り付けられた軸受カバー７では、使用により清掃片１０（又は１１）が摩耗すれば、簡単に取り外して新しいものに交換することができる。したがって、清掃片１０（又は１１）のみの交換で長期に亘って使用することが可能となる。 In the embodiment described above, the cleaning pieces 10 and 11 are attached to the bearing cover 7 with an adhesive or the like, but the cleaning pieces 10 and 11 may be detachable as shown in FIG. That is, the engaging groove 9 b having a substantially semicircular cross section is formed in the protruding portion 9 a provided on the side surface portion 9 of the bearing cover 7. The engagement groove 9b is formed so as to gradually expand toward the tip. On the other hand, on the rear end side of the cleaning piece (only the first cleaning piece 10 is shown here), a substantially semi-columnar mounting portion 10c that can be attached to and detached from the engaging groove 9b is formed. Then, as shown by the arrow in FIG. 7A, the attachment portion 10c is press-fitted into the engagement groove 9b to be attached. In the bearing cover 7 to which the cleaning piece 10 (or 11) is attached in this manner, if the cleaning piece 10 (or 11) is worn by use, it can be easily removed and replaced with a new one. Therefore, it becomes possible to use it for a long time by exchanging only the cleaning piece 10 (or 11).
また、清掃片１０、１１は、軸受カバー７以外に設けることも可能である。例えば、支持プレート１に支持部（図示せず）を形成し、この支持部に清掃片１０、１１を設けることも可能である。この場合、軸受カバー７を取り外した状態であっても、清掃片１０、１１は軸受ローラ５に摺接可能な状態を維持する。 Further, the cleaning pieces 10 and 11 can be provided other than the bearing cover 7. For example, a support portion (not shown) may be formed on the support plate 1 and the cleaning pieces 10 and 11 may be provided on the support portion. In this case, even when the bearing cover 7 is removed, the cleaning pieces 10 and 11 maintain a state in which the cleaning pieces 10 and 11 can be brought into sliding contact with the bearing roller 5.
前記実施形態では、軸受ローラ５に対する軸受カバー７の装着構造については特に触れなかったが、例えば、図８に示す構成とすることができる。すなわち、軸受カバー７には、その側面部９の両端部外周面に係止受部２２をそれぞれ形成する一方、支持プレート１から係止ピン２３を突出させる。そして、軸受カバー７で軸受ローラ５を覆う際、係止受部２２に係止ピン２３を係止させて装着する。この場合、係止受部２２は先端に向かって徐々に広がるように形成されているので、係止ピン２３はスムーズに係止受部２２へと侵入する。このため、係止ピン２３や係止受部２２が損傷しにくくなる。そして、装着状態では、軸受ローラ５には、軸受カバー７の第２清掃片１１のみが摺接するだけである。したがって、軸受ローラ５に支持リング４による回転力が付与された場合、その回転の妨げとなるのが第２清掃片１１のみとなり、前述のものに比べて軸受ローラ５の回転がスムーズになり、散薬分配皿２の回転状態を安定させることができる。 In the embodiment, the mounting structure of the bearing cover 7 with respect to the bearing roller 5 is not particularly mentioned, but for example, the configuration shown in FIG. That is, the bearing cover 7 is formed with locking receiving portions 22 on the outer peripheral surfaces of both end portions of the side surface portion 9, while the locking pins 23 are projected from the support plate 1. When the bearing roller 5 is covered with the bearing cover 7, the locking pin 23 is locked to the locking receiving portion 22 and attached. In this case, since the latch receiving part 22 is formed so as to gradually expand toward the tip, the latch pin 23 smoothly enters the latch receiving part 22. For this reason, the locking pin 23 and the locking receiving portion 22 are not easily damaged. In the mounted state, only the second cleaning piece 11 of the bearing cover 7 is in sliding contact with the bearing roller 5. Therefore, when the rotational force by the support ring 4 is applied to the bearing roller 5, only the second cleaning piece 11 prevents the rotation, and the rotation of the bearing roller 5 becomes smoother than the above, The rotation state of the powder distribution tray 2 can be stabilized.
前記実施形態では、軸受ローラ５で支持リング４の内縁部４ａを支持するようにしたが、図１０に示すように、支持リング４に外縁部４ｂを形成し、外周側で支持するように構成することも可能である。 In the above embodiment, the inner edge 4a of the support ring 4 is supported by the bearing roller 5. However, as shown in FIG. 10, the outer edge 4b is formed on the support ring 4 and supported on the outer peripheral side. It is also possible to do.
前記実施形態では、散薬分配皿２の底面側に形成した支持リング４の内縁部４ａ又は外縁部４ｂを軸受ローラ５で回転可能に支持するようにしたが、支持リング４は、図１１及び図１２（ａ）に示すように、散薬分配皿２から外径方向に延在させた外縁部２ａで構成してもよいし、図１２（ｂ）に示すように、内径方向に延在させた内縁部２ｂで構成してもよい（図中、矢印は散薬の掻き出し方向を示している。）。これによれば、重量の大きな支持リング４を散薬分配皿２の一部で構成することができるので、全体として軽量化を図ることができ、動力源や回転軸等への負荷を軽減して長期に亘って良好な回転状態を維持することが可能となる。 In the said embodiment, although the inner edge part 4a or the outer edge part 4b of the support ring 4 formed in the bottom face side of the powder distribution tray 2 was supported rotatably by the bearing roller 5, the support ring 4 is shown in FIGS. As shown to 12 (a), you may comprise by the outer edge part 2a extended from the powder distribution tray 2 to the outer-diameter direction, and was made to extend to the inner-diameter direction as shown in FIG.12 (b). You may comprise by the inner edge part 2b (in the figure, the arrow has shown the scraping-out direction of a powder). According to this, since the heavy support ring 4 can be constituted by a part of the powder distribution tray 2, the overall weight can be reduced, and the load on the power source and the rotating shaft can be reduced. It becomes possible to maintain a good rotation state over a long period of time.
支持リング４を散薬分配皿２の一部で構成する場合、外縁部２ａ又は内縁部２ｂを軸受ローラ５で回転可能に支持するようにすればよい。そして、軸受ローラ５による支持位置は、掻出装置１２による散薬の掻出方向とは同じ側でもよいが、反対側とするのが好ましい。図１２（ａ）では、掻出装置１２によって散薬分配皿２から散薬を内径方向に掻き出しており、軸受ローラ５による支持位置を外径側としている。また、図１２（ｂ）では、散薬を外径方向に掻き出しており、軸受ローラ５による支持位置を内径側としている。これにより、軸受ローラ５への散薬の付着をより一層効果的に防止することが可能となる。 When the support ring 4 is constituted by a part of the powder distribution tray 2, the outer edge portion 2a or the inner edge portion 2b may be rotatably supported by the bearing roller 5. And the support position by the bearing roller 5 may be on the same side as the powder scraping direction by the scraping device 12, but is preferably on the opposite side. In FIG. 12A, the scraping device 12 scrapes the powder from the powder distribution tray 2 in the inner diameter direction, and the support position by the bearing roller 5 is the outer diameter side. Moreover, in FIG.12 (b), powdered medicine is scraped out to the outer diameter direction, and the support position by the bearing roller 5 is made into the inner diameter side. Thereby, it becomes possible to prevent adhesion of powder medicine to the bearing roller 5 more effectively.
図１１及び図１２中、２４、２５は散薬フィーダである。散薬フィーダ２４は、図１１（ａ）及び図１２（ａ）、（ｂ）中、右方向に向かって散薬を供給し、散薬フィーダ２５は、図１１（ｂ）及び図１２（ａ）、（ｂ）中、左方向に向かって散薬を供給するものである。散薬分配皿２の底面には、下方に向かって円筒状の従動ギア２ｃが形成されている。この従動ギア２ｃには、図示しないモータの回転軸に設けた駆動ギア２ｄが噛合し、動力が伝達されるようになっている。 11 and 12, 24 and 25 are powder feeders. The powder feeder 24 supplies the powder in the right direction in FIGS. 11 (a), 12 (a), and 12 (b), and the powder feeder 25 is used in FIGS. 11 (b), 12 (a), ( b) In the middle, powder is supplied in the left direction. On the bottom surface of the powder distribution tray 2, a cylindrical driven gear 2c is formed downward. The driven gear 2c meshes with a drive gear 2d provided on a rotating shaft of a motor (not shown) so that power is transmitted.
