Description

【０００１】
【発明の属する技術分野】
本発明は、薬剤包装装置によって包装された帯状の薬包体を搬送するための薬包体搬送装置に関するものである。
【０００２】
【従来の技術】
従来、薬剤包装装置によって包装された帯状の薬包体は、例えば、次のような搬送装置によって、下方から作業のしやすい上方位置まで搬送されている。
【０００３】
特許第２５３８３５０号公報には、複数のローラにそれぞれ掛け渡した一対の平ベルトを所定間隙寸法の搬送通路が形成されるように配置し、テンション装置によって前記平ベルトに作用するテンションを調整可能としたものが開示されている。
【０００４】
特開平５−１３２００８号公報には、包装体案内走行手段によって挿入口に案内した包装体を、テンションアームに設けた押圧ローラによって緊張状態に維持しつつ、搬送ベルトの間に挟持して搬送するようにした包装体排出案内搬送装置が開示されている。
【０００５】
【発明が解決しようとする課題】
しかしながら、前記いずれの構成であっても、薬包体を一定間隔に維持されたベルトの隙間に挟持して搬送するようにしている。このため、薬包体に収容される薬剤量が多くなって膨らんだ場合には、詰まったり、薬包体が破れたり等の問題が発生する。
【０００６】
そこで、本発明は、薬包体に作用する張力に応じて搬送速度を調整可能としつつ、薬包体の損傷を確実に防止することのできる薬包体搬送装置を提供することを課題とする。
【０００７】
【課題を解決するための手段】
本発明は、前記課題を解決するための手段として、薬剤包装装置で形成されて供給される帯状の薬包体を搬送する薬包体搬送装置において、前記薬包体を両側から挟持し、その長手方向に搬送する第１ベルトコンベア及び第２ベルトコンベアを有し、前記第２ベルトコンベアを、搬送方向下流側を中心として前記第１ベルトコンベアに対して接離する方向に回動自在に設けてなる搬送手段と、前記薬剤包装装置から供給される薬包体に応じて回動する第２ベルトコンベアの回動位置を検出する回動検出手段と、該回動検出手段が検出する前記第２ベルトコンベアの回動位置に応じて、前記両ベルトコンベアによる搬送速度を制御する制御手段とを備え、前記薬包体は、前記両コンベアによる搬送開始位置と、前記回動中心とを結ぶ平面に対し、前記第２コンベアが位置する側から、前記搬送手段へと供給されるようにしたものである。
【０００８】
この構成により、薬剤包装装置からの薬包体の供給速度の変化に応じて第２ベルトコンベアが回動し、両ベルトコンベアによる搬送を自動的に調整することができる。また、薬包体に収容される薬剤が多くなって膨らんだ場合にも、第２ベルトコンベアが回動自在であるため、薬包体を損傷させることはない。
【０００９】
前記第１ベルトコンベアは、前記薬剤包装装置から供給される薬包体を略水平方向に搬送する水平搬送部を備え、該水平搬送部に前記薬包体を押し付ける押圧部材を設けると、薬剤包装装置から下方に供給された薬包体をスムーズに上方側へと導くことが可能となる点で好ましい。
【００１１】
また、本発明は、前記課題を解決するための手段として、薬剤包装装置で形成されて供給される帯状の薬包体を搬送する薬包体搬送装置において、
前記薬包体を両側から挟持し、その長手方向に搬送する第１ベルトコンベア及び第２ベルトコンベアを有し、前記第１ベルトコンベアは、前記薬剤包装装置から供給される薬包体を略水平方向に搬送する水平搬送部を備え、該水平搬送部に前記薬包体を押し付ける押圧部材を設け、前記第２ベルトコンベアは、搬送方向下流側を中心として前記第１ベルトコンベアに対して接離する方向に回動自在に設けてなる搬送手段と、
前記押圧部材の回動位置を検出する回動検出手段と、
前記回動検出手段が検出する押圧部材の回動位置に応じて、前記両ベルトコンベアによる搬送速度を制御する制御手段とを備えた構成としたものである。
【００１２】
【発明の実施の形態】
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。
【００１３】
図１は、本実施形態に係る薬包体搬送装置１を備えた薬剤包装装置を示す。薬剤包装装置では、図示しないＲ円盤や錠剤フィーダ等から供給される薬剤（散薬、錠剤等）がホッパー２を介して払い出される。ホッパー２の下方には、ロール３から巻き戻された帯状の包装紙が、プリンター４によって薬剤名や用法等を印刷された後、２つ折りにされた状態で供給される。包装紙には１包分の薬剤が収容される毎にシール装置５によって封止される。これにより、図４に示すように帯状に連なった薬包体１００が形成される。
【００１４】
薬包体搬送装置１は、図２及び図３に示すように、略Ｌ字形のケーシング６に、第１ベルトコンベア７、第２ベルトコンベア８、押圧部材９等を備え、薬包体１００の搬送等は制御装置１０によって制御される。
【００１５】
第１ベルトコンベア７は、回転自在に設けた複数のローラ１１ａ，１１ｂ，１１ｃ，１１ｄ，１１ｅ，１１ｆに平ベルト１２を掛け渡したもので、水平搬送部７ａと垂直搬送部７ｂとで構成されている。ケーシング６の上端部に設けたローラ１１ａにはギア１３が設けられている。ギア１３にはギア１４が噛合し、ギア１４にはプーリ１５が一体化されている。また、ケーシング６の角部に設けたローラ１１ｆにはギア１７ａ及びプーリ１７ｂが設けられ、ギア１７ａはモータ１８の回転軸に設けたギア１９と噛合している。これにより、モータ１８が駆動すると、ギア１７ａ，１９を介してローラ１１ｆが回転し、平ベルト１２が矢印方向に移動する。前記水平搬送部７ａは、平ベルト１２の上方側に位置する部分が垂直搬送部７ｂに向かって徐々に上方に傾斜し、又、下面がガイド板２０によってガイドされている。なお、前記ローラ１１ｃにはテンション調整部３０が設けられ、ローラ１１ｃを水平方向に移動可能とすることにより、平ベルト１２に作用するテンションを調整可能となっている。
【００１６】
第２ベルトコンベア８は、前記第１ベルトコンベア７と同様、回転自在に設けた複数のローラ２１ａ，２１ｂ，２１ｃ，２１ｄに平ベルト２２を掛け渡したもので、ケーシング６には前記ローラ２１ａを中心として回動自在に取り付けられている。ローラ２１ａにはプーリ２３が一体化され、このプーリ２３と前記第１ベルトコンベア７のプーリ１５との間に架け渡されたベルト２４によって前記モータ１８からの動力が伝達される。これにより、第２ベルトコンベア８は、前記第１ベルトコンベア７と同期して駆動し、対向する平ベルト１２，２２が共に下方から上方に向かって移動する。また、第２ベルトコンベア８の回動位置は、ビームセンサ等からなる回動位置検出センサ（図示せず）によって検出される。ここでは、第２ベルトコンベア８が垂直位置からある一定の角度以上に回動することにより、回動位置検出センサでの検出信号がオンからオフに切り替わるようになっている。なお、前記ローラ１１ｃには、前記第１ベルトコンベア７と同様なテンション調整部３１が設けられている。
【００１７】
押圧部材９は、ケーシング６に支軸２５ａを中心として回動自在に設けた押圧板２５からなる。この押圧板２５は、図示しないスプリングや自重等によって先端側が第１ベルトコンベア７の水平搬送部７ａ側に付勢されている。これにより、供給された薬包体１００を確実に第１ベルトコンベア７の水平搬送部７ａに押し付けて薬包体１００の搬送を可能とする。また、押圧部材９の近傍にはガイドローラ２６が設けられている。ガイドローラ２６の一端部にはプーリ２６ａが設けられ、前記ローラ１１ｆの一端部に設けたプーリ１７ｂとの間にはベルト２７が掛け渡されている。これにより、モータ１８を駆動すると、プーリ１７ｂ，ベルト２７、プーリ２６ａを介してガイドローラ２６が回転し、薬包体１００を水平搬送部７ａ側へと搬送可能となっている。さらに、ガイドローラ２６の下方近傍には補助ローラ２８が回転自在に設けられ、ガイドローラ２６によって薬包体１００が水平搬送部７ａ側ではなく、上方側に方向変換されることが防止されている。
【００１８】
制御装置１０は、前記回動位置検出センサでの検出信号に基づいてモータ１８への通電を制御する。
【００１９】
次に、前記薬包体搬送装置１の動作を説明する。
【００２０】
処方データに基づいて１包分ずつ包装されることにより薬包体１００が薬包体搬送装置１へと払い出される。払い出された薬包体１００は、第１ベルトコンベア７の水平搬送部７ａに当接し、モータ１８の駆動によって移動する平ベルト１２に従って略水平方向、詳しくは斜め上方に向かって搬送される。そして、薬包体１００は第１ベルトコンベア７と第２ベルトコンベア８との間に導かれ、上方へと搬送方向を変換された後、上端部から排出される。この間、薬包体１００はケーシング６と両ベルトコンベア１２，２１によって囲まれた空間を移動し、埃等の付着が防止される。
【００２１】
ところで、薬包体１００に収容される薬剤のサイズや量は種々あり、薬包体１００の膨らみ具合も相違する。また、薬包体１００は、薬包体搬送装置１によって垂直方向に搬送される際、図４（ｂ）に示すように、収容した薬剤が下方側に偏り、部分的な膨らみが大きくなる。この場合、薬包体１００の膨らみ具合に応じて第２ベルトコンベア８が支軸を中心として回動する。したがって、薬包体１００に無理な負荷が作用せず、薬包体１００が破れる等の損傷を受けることがない。
【００２２】
また、薬包体搬送装置１への薬包体１００の供給速度は、処方される薬剤の種類や容量等の違いによって変化する。一方、薬包体搬送装置１による薬包体１００の搬送速度は一定である。このため、薬包体１００の供給速度が薬包体搬送装置１による搬送速度よりも小さくなると、薬包体１００に引っ張り力が作用する。この場合、第２ベルトコンベア８が回動し、その回動位置が回動位置検出センサによって検出されると（センサからオフ信号が出力されると）、強制的にモータ１８の駆動が停止される。これにより、薬包体１００に作用する引っ張り力が抑制され、薬包体１００が損傷に至ることはない。また、第２ベルトコンベア８が回動し過ぎた場合にのみ回動位置検出センサからオフ信号を出力するようにしている。このため、故障等で出力信号がオフ状態となった場合にはモータ１８の駆動が停止され、誤作動が防止される。
【００２３】
なお、前記実施形態では、第１ベルトコンベア７に水平搬送部７ａを備えた構成とすると共に、押圧部材９を設けるようにしたが、これらは必ずしも必要なものではない。すなわち、供給された薬包体１００を直接垂直方向に延びるベルトコンベア７，９の間に供給するようにしても構わない。この場合、薬包体１００がスムーズに両ベルトコンベア７，９の間に供給されるようなガイドを設けるのが好ましい。
【００２４】
また、前記実施形態では、第２ベルトコンベア８の回動位置を回動位置検出センサで検出することにより、薬包体１００に作用する引っ張り力が大きくなり過ぎないようにモータ１８を駆動制御するようにしたが、このモータ１８は前記押圧板２５の回動位置を検出することにより駆動制御するようにしても構わない。
【００２５】
【発明の効果】
以上の説明から明らかなように、本発明によれば、第２ベルトコンベアを回動自在に設け、薬剤包装装置から供給される薬包体の供給速度に応じて両ベルトコンベアによる搬送を自動的に調整するようにしたので、薬包体に作用する張力に応じて搬送速度を調整可能としつつ、薬包体に収容される薬剤量が多い場合であっても、薬包体を損傷させることなくスムーズに搬送することが可能となる。

DETAILED DESCRIPTION OF THE INVENTION
Embodiments according to the present invention will be described below with reference to the accompanying drawings.
[0013]
FIG. 1 shows a medicine packaging apparatus provided with a medicine package transport apparatus 1 according to this embodiment. In the medicine packaging device, medicines (powder, tablets, etc.) supplied from an R disk or tablet feeder (not shown) are dispensed through the hopper 2. Below the hopper 2, a strip-shaped wrapping paper unwound from the roll 3 is supplied in a state of being folded in two after the medicine name and usage are printed by the printer 4. The wrapping paper is sealed by the sealing device 5 every time one pack of medicine is stored. Thereby, as shown in FIG. 4, the medicine package 100 connected in a strip shape is formed.
[0014]
As shown in FIGS. 2 and 3, the medicine package transport apparatus 1 includes a first belt conveyor 7, a second belt conveyor 8, a pressing member 9, and the like in a substantially L-shaped casing 6. The conveyance and the like are controlled by the control device 10.

A roller 17 f provided at the corner of the casing 6 is provided with a gear 17 a and a pulley 17 b, and the gear 17 a meshes with a gear 19 provided on the rotation shaft of the motor 18. Thus, when the motor 18 is driven, the roller 11f rotates via the gears 17a and 19 and the flat belt 12 moves in the direction of the arrow. In the horizontal conveying portion 7a, a portion located on the upper side of the flat belt 12 is gradually inclined upward toward the vertical conveying portion 7b, and the lower surface is guided by a guide plate 20. The roller 11c is provided with a tension adjusting unit 30, and the tension acting on the flat belt 12 can be adjusted by allowing the roller 11c to move in the horizontal direction.
[0016]
Similar to the first belt conveyor 7, the second belt conveyor 8 includes a plurality of rollers 21 a, 21 b, 21 c, and 21 d that are rotatably provided with a flat belt 22 laid on the casing 6. It is pivotally attached as the center. A pulley 23 is integrated with the roller 21 a, and power from the motor 18 is transmitted by a belt 24 laid between the pulley 23 and the pulley 15 of the first belt conveyor 7. As a result, the second belt conveyor 8 is driven in synchronization with the first belt conveyor 7, and the opposed flat belts 12 and 22 both move upward from below. Further, the rotational position of the second belt conveyor 8 is detected by a rotational position detection sensor (not shown) made up of a beam sensor or the like. Here, when the second belt conveyor 8 rotates more than a certain angle from the vertical position, the detection signal at the rotation position detection sensor is switched from on to off.

The dispensed medicine package 100 is in contact with the horizontal conveying portion 7a of the first belt conveyor 7, and is conveyed substantially horizontally, specifically obliquely upward, according to the flat belt 12 that is moved by driving the motor 18. And the medicine package 100 is guide | induced between the 1st belt conveyor 7 and the 2nd belt conveyor 8, and after the conveyance direction is changed upwards, it is discharged | emitted from an upper end part. During this time, the medicine pack 100 moves in the space surrounded by the casing 6 and the two belt conveyors 12 and 21, and adhesion of dust and the like is prevented.
[0021]
By the way, there are various sizes and amounts of the medicines accommodated in the medicine pack 100, and the swelling state of the medicine pack 100 is also different. Further, when the medicine pack 100 is transported in the vertical direction by the medicine pack transport apparatus 1, as shown in FIG. 4 (b), the contained medicine is biased downward, and the partial swelling increases. In this case, the second belt conveyor 8 rotates around the support shaft according to the degree of swelling of the medicine pack 100. Therefore, an unreasonable load does not act on the medicine pack 100 and the medicine pack 100 is not damaged such as tearing.
[0022]
Moreover, the supply speed of the medicine pack 100 to the medicine pack transport apparatus 1 varies depending on the kind of medicine to be prescribed, the capacity, and the like. On the other hand, the transport speed of the medicine pack 100 by the medicine pack transport apparatus 1 is constant. For this reason, when the supply speed of the medicine pack 100 becomes lower than the transport speed by the medicine pack transport device 1, a tensile force acts on the medicine pack 100. In this case, when the second belt conveyor 8 rotates and the rotation position is detected by the rotation position detection sensor (when an off signal is output from the sensor), the driving of the motor 18 is forcibly stopped. The Thereby, the pulling force which acts on the medicine pack 100 is suppressed, and the medicine pack 100 does not reach damage. Further, an off signal is output from the rotation position detection sensor only when the second belt conveyor 8 rotates too much. For this reason, when the output signal is turned off due to a failure or the like, the driving of the motor 18 is stopped and malfunction is prevented.
[0023]
In the above-described embodiment, the first belt conveyor 7 includes the horizontal conveyance unit 7a and the pressing member 9 is provided. However, these are not necessarily required. That is, you may make it supply the supplied medicine package 100 between the belt conveyors 7 and 9 extended in a perpendicular direction directly. In this case, it is preferable to provide a guide that allows the medicine pack 100 to be smoothly supplied between the belt conveyors 7 and 9.
[0024]
Moreover, in the said embodiment, the motor 18 is drive-controlled so that the pulling force which acts on the medicine package 100 may not become large by detecting the rotation position of the 2nd belt conveyor 8 with a rotation position detection sensor. However, the motor 18 may be driven and controlled by detecting the rotational position of the pressing plate 25.
[0025]
【The invention's effect】
As is clear from the above description, according to the present invention, the second belt conveyor is provided so as to be rotatable, and the conveyance by the two belt conveyors is automatically performed according to the supply speed of the medicine package supplied from the medicine packaging device. It is possible to adjust the transport speed according to the tension acting on the medicine pack, and damage the medicine pack even if the amount of medicine contained in the medicine pack is large. It is possible to transport smoothly.
