【発明の属する技術分野】
本発明は、コンベヤ搬送を利用したプラントにおいて、プラントを構成する機器の運転状況やコンベヤ上の物品の流れ状況に応じてコンベヤ上の物品の滞留数量を制御するバッファ装置及び方法に関するものである。
【0002】
【従来の技術】
びん、袋物、箱物等の物品の生産・充填プラント等において、プラントを構成する機器の不具合発生時等に機器の発停頻度を減少させてプラントの円滑な稼動を図ることを目的として、機種間をつなぐコンベヤの途上に各種のバッファ装置が設置されて利用されている。従来、規定列で搬送する物品をさらに幅広のコンベヤ上に導入して規定列より多列化して滞留させ、不具合等の解消後に集合コンベヤ上で物品を規定列に集合して下流コンベヤに流す方式が多く利用されていた。この場合、取扱う物品の種類により多列から規定列に物品を集合する際、物品の転倒やジャムが発生することや、物品の種類によっては実際上物品の集合が困難ない場合があった。また、物品の先入れ先出しが必ずしも保証されない問題が有った。また、調整困難で性能が必ずしも安定しなかった。
【0003】
【発明が解決しようとする課題】
本発明は上記の問題点を解決して、物品の搬送列数を維持したままで物品の転倒やジャム並びにラインプレッシャによる物品への無理な応力を排除するとともに、物品の先入れ先出しを確保した簡易な構成の物品バッファコンベヤ装置及び物品のバッファ方法を提案するものである。
【0004】
【課題を解決するための手段】
請求項1に記載の発明は、搬送する物品の滞留数量を増減させてプラントの円滑な稼動を図るために搬送コンベヤの途上に配設されるバッファコンベヤ装置であって、1組の正行する往路コンベヤ及びこれに離間して平行に配設された逆行する復路コンベヤと、往路コンベヤと復路コンベヤの間に設置されて物品の進行方向を往路コンベヤ進路から復路コンベヤ進路に反転させて移送する物品反転ガイド及び駆動された転送円盤を備えた転送装置と、転送装置をコンベヤの進行方向に往復動自在に移動可能とした転送装置移動手段とを備えたことを特徴とする物品バッファコンベヤ装置を提供することを要旨とする。
【0005】
請求項2の発明は、請求項1に示す物品バッファコンベヤ装置を隣接して複数個配設し、物品搬送の上流側に配置した物品バッファコンベヤ装置の復路コンベヤの物品排出部とこれに隣接して下流側に配置した物品バッファコンベヤ装置の往路コンベヤの物品供給端部との間に、物品移送用の駆動された移送装置を備えたことを特徴とする物品バッファコンベヤ装置を提供することを要旨とする。本発明により物品バッファコンベヤ装置における物品の滞留可能数量を増大させて、バッファ装置としての物品数量調整機能を増大させる事が出来る。
【0006】
請求項3の発明は、請求項1及び2において、物品バッファコンベヤ装置を構成する往路コンベヤ及び、または復路コンベヤがそれぞれ複数のコンベヤに分割されて直列に配置され、かつ分割された複数のコンベヤがそれぞれ個別に駆動装置を備えたことを特徴とする物品バッファコンベヤ装置を提供することを要旨とする。本発明により、バッファ装置全体の往路コンベヤ及び復路コンベヤのうち、バッファ装置の運転状況に対応した物品の滞留に使用するコンベヤ部分のみを個別に稼動させて利用することが出来るため、駆動力の省エネルギ効果と部品等の磨耗・損傷の低減を図ることが出来る。
【0007】
請求項4の発明は、請求項1乃至3において、プラントを構成する機器の稼動状況データ、並びに物品バッファコンベヤ装置の上流側の供給コンベヤ、下流側の排出コンベヤ、及び物品バッファコンベヤの内部における物品搬送状況データを処理して、物品バッファコンベヤ装置を構成する往路コンベヤ、復路コンベヤ、転送円盤及び移送装置の駆動速度並びに転送装置移動手段の位置を個別に制御するバッファ制御装置を備えたことを特徴とする物品バッファコンベヤ装置を提供することを要旨とする。本発明により、プラントの稼動状況に適合した好適な物品バッファコンベヤ装置の運転が可能となる。
【0008】
請求項5の発明は、コンベヤを使用するプラントの円滑稼動を図るためのバッファ方法であって、正行する往路コンベヤとこれに離間して平行に配設された逆行する復路コンベヤ間に、物品の進行方向を往路コンベヤ上から復路コンベヤ上に反転、移送させるための転送円盤及び物品反転ガイドを備えた転送装置を設け、往路コンベヤ及び復路コンベヤ並びに転送円盤の駆動速度を個別に制御し,かつ、転送装置のコンベヤの進行方向位置を制御して移動させることにより、プラントの稼動状況に応じて物品のバッファ機能を発現させることに特徴とする物品のバッファ方法を提供することを要旨とする。
【0009】
【発明の実施の形態】
以下、この発明を具体化した実施例を図1〜図6により説明する。図1は実施例として複数列の物品バッファコンベヤ装置を接続利用した場合の全体平面図、図2は本特許の基本的な構成としての個別バッファコンベヤ1aの平面図、図3は図2の正面図、図4は転送装置の構造を示す図2のX−X断面図、図5及び図6はそれぞれ図2のY−Y断面図及びZ−Z断面図である。
【0010】
図1において、物品Bは上流に設置された図示省略の機器から供給コンベヤ2を経由して物品バッファコンベヤ装置1に供給され、物品バッファコンベヤ装置1内部を搬送され、排出コンベヤ3に排出されて下流の機器に供給される。本実施例において物品バッファコンベヤ装置1は、本発明の基本的な構成要素である4セットの個別バッファ装置1a乃至1dと、その間を接続して物品Bを搬送する駆動された転送円盤と物品ガイドを備えた3組の移送装置4a乃至4cにより構成されている。また、個別バッファ装置1a乃至1dにはそれぞれ物品Bの進行を往路コンベヤ上から復路コンベヤ上に反転させる5a乃至5dが備えられている。
【0011】
また、個別バッファ装置1a及び1bにおいては転送装置5a及び5bは移動範囲の図示左端に有ってコンベヤ上の物品Bの滞留数量を最小とした状態を示し、個別バッファ装置1dにおいては、転送装置5dが図示右端部に移動して物品滞留数量を最大とした状態、個別バッファ装置1cにおいてはその中間の物品滞留状態を示す。また、物品センサ23、24はそれぞれ供給コンベヤ2及び排出コンベヤ3上の物品Bの有無や単位時間あたりの物品Bの通過量等を検出する機能を果たす。
【0012】
図2は本発明の基本的な構成の実施例としての個別バッファ装置1aの平面図を示し、往路コンベヤ6aと復路コンベヤ7aは平行に配設されて、それぞれ矢印A及びC方向に進行する。転送装置5aを構成する転送円盤9は矢印Dの方向に回転して物品Bを往路コンベヤ6aから復路コンベヤ7aに転送する機能を有し、詳細後述の転送装置移動手段25により矢印Eの如くコンベヤの進行方向に往復移動することが出来る。なお、移動物品ガイド11は転送円盤9の上部に配設されてその供給、排出部方向に延長され、物品Bの方向転換を案内する機能を有し、転送装置5aの一部として一体に移動する。また、往路コンベヤ6aは往路コンベヤ6aa、6abに、復路コンベヤ7aは復路コンベヤ7aa、7abにそれぞれ2分割され、個別に駆動モータ8により駆動される。即ち、これらの各コンベヤは、それぞれのコンベヤに要求される運転条件に従って駆動条件を変更して独立して駆動することが出来る。
【0013】
図3の個別バッファ装置1aの正面図に示す如く、往路コンベヤ6aを構成する往路コンベヤ6aa、6abは直列に配置接続され、物品搬送面の直角方向に曲げ半径の小さいコンベヤチエン17を使用することにより物品Bが円滑に往路コンベヤ6aa、6abの間を搬送される。なお、コンベヤチエン17の駆動は接続するコンベヤ等との干渉を避ける為、図示の如く駆動モータ8を下部に配置した駆動構成となっている。
【0014】
図4に示す転送装置5aの詳細構造を示す断面図において、転送装置5aの基部をなす移動フレーム16は復路コンベヤ7a及び対向する往路コンベヤ6aに固定されたスライドレール10によりコンベヤ進行方向に往復動自在に支持されている。また、両端を固定されたタイミングベルト18は移動フレーム16に固定された2個のプーリ20に係合し、移動モータ19が駆動プーリ21を駆動して、タイミングベルト18を介して移動フレーム16をコンベヤの進行方向に往復移動させる。移動フレーム16は移動物品ガイド11を取り付けるガイド枠14及び転送円盤9を備え、軸支された転送円盤9は転送モータ12により駆動される。なお、ケーブルガイド22は転送装置の移動に対応してモータに電力を供給する為の電線の移動を円滑化させる。また図6の断面図は移動フレーム16における移動モータ19と駆動プーリ21の取付け関係を示す。
【0015】
図5に示す如く、転送装置5aは往路コンベヤ6aと復路コンベヤ7aの間に配設され、移動フレーム16はスライドレール10と係合するスライドローラ13を備え、往路コンベヤ6aと復路コンベヤ7aに固定されたスライドレール10によりコンベヤ進行方向に移動自在に支持されている。図示例において、転送円盤9の上面は往路コンベヤ6a及び復路コンベヤ7aの上面と同じ高さとしているが、物品Bの円滑な搬送をうながす為多少の段差をつけることも出来る。また、転送円盤9は両コンベヤに内側端部に接する直径としているが、物品Bの種類によっては往路コンベヤ6及び復路コンベヤ7の物品搬送面を覆う直径とする事も出来る。
【0016】
以下、実施例に基づく物品バッファコンベヤ装置1における各構成要素の作動及び機能に関して説明する。図1において供給コンベヤ2から供給された物品Bは物品バッファコンベヤ装置1に供給され、個別バッファ装置1aから順次個別バッファ装置1dを経由して排出コンベヤ3から排出されて下流に設置された機器に搬送される。図示の如く、物品Bが個別バッファ装置1dの全面及び個別バッファ装置1cの略半分の領域に滞留している場合において、供給側と排出側の運転能力が同一の際は、物品バッファコンベヤ装置1を構成する物品Bの各搬送装置はこの運転能力と同一の物品搬送能力で運転される。以下、プラントの基準能力Vkをベースとし高速能力Vh及び低速能力Vlを利用して、プラントの各種状況における物品バッファコンベヤ装置1の作動及び機能を説明する。
【0017】
図1において、例えば下流側機器の故障により排出コンベヤ3が停止して供給コンベヤ2から基準能力Vkに対応する物品Bが供給され続ける場合、個別バッファ装置1cの転送装置5cは逐次図示の右方向に移動してコンベヤ上に物品Bをさらに滞留させる。この時、転送装置5cの移動速度は供給コンベヤから個別バッファ装置1cの往路コンベヤに至る物品搬送速度の略1/2と成る。また、この状態で個別バッファ装置1dと移送装置4c、復路コンベヤ7caは駆動を停止し、他の物品Bの搬送装置は基準能力Vkでの運転を継続する。その後、個別バッファ装置1cが満杯になった場合、順次個別バッファ装置1b、個別バッファ装置1aに物品Bを滞留させ、個別バッファ装置1aが満杯になって停止するまで上流側機器及び供給コンベヤ2の運転を継続することが出来る。
【0018】
図1において、下流側の不具合が解消して物品Bの処理が円滑となり、運転能力を基準能力Vk以上に上げる条件が整った場合、排出コンベヤ3の能力は高速能力Vhに上げられて物品Bの搬送速度が上げることが出来る。この時は、個別バッファ装置1c、1d及び移送装置4cの運転速度を排出コンベヤ3に連動して高速能力Vhに増速する。一方、これに対応して転送装置5cは所定速度で逐次図示左方向に移動させて、供給コンベヤ2から個別バッファ装置1cへの物品供給量と個別バッファ装置1cから下流側への排出量の差をおぎなう形で個別バッファ装置1c上の物品の滞留数量を減少させる。
【0019】
その後、個別バッファ装置1cの転送装置5cが図示左方向に移動してその移動範囲の終端位置まで移動した後は、個別バッファ装置1dの転送装置5dを前述同様に図示左方向に移動させて物品の滞留数量を減少させる。以後、個別バッファ装置1dの転送装置5cが図示左方向の終端位置に達した場合、図示省略の下流機器、排出コンベヤ3及びバッファコンベヤ装置1全体の運転能力を基準能力Vkに戻して運転を行なう。
【0020】
なお、図1において、供給コンベヤ2からの物品Bの供給が停止して排出コンベヤ3が稼動している場合は、個別バッファ装置1a、1bの及び移送装置4aを停止して、個別バッファ装置1c、1d上の余分に滞留する物品Bを排出させ、各転送装置を図示左終端に戻して物品バッファコンベヤ装置1全体を停止させる。なお、この場合に物品Bの種類やプラントの特性によっては、物品バッファコンベヤ装置1内部の物品Bを可能な限り排出して、物品Bを残さない生産方式を採用することが出来る。
【0021】
以上、本発明に基づく物品バッファコンベヤ装置1のバッファ装置としての作動及び機能を基本的な運転条件に対して説明したが、物品バッファコンベヤ装置1の運転は特に前述の条件に限定されるものではなく、本発明の主旨の範囲でプラントの構成、取扱う物品Bの種類及び運転条件に対応して各種の運転が可能である。これら物品バッファコンベヤ装置1の運転条件の制御は、物品バッファコンベヤ装置1の上下流機器の稼動状況に関するデータ並びに供給コンベヤ2,排出コンベヤ3に配置された物品センサ23、24の物品搬送状況に関するデータ等を、図示省略の制御データ処理装置で別途処理して各部の駆動モータの回転速度を制御して行なう。
【0022】
なお、実施例において、取扱う物品Bを全数直接、物品バッファコンベヤ装置1に供給する場合に関して説明したが、本装置をプラントのコンベヤ主流に対してバイパスラインとして設置し、バッファ機能が要求される場合にのみ本バッファ装置に物品Bを導入または排出させて使用することも出来る。また、4セットの個別バッファ装置1a〜1dを使用した場合を例示したが、プラントにおいて要求されるバッファ装置としてのバッファ容量に従って個別バッファ装置のセット数は自由に選択出来る。また、個別バッファ装置1a乃至1dは直線コンベヤを例示したが、必要に応じてカーブコンベヤを利用してレイアウトに曲線部を設ける等設置場所の要求に対応することも出来る。
【0023】
なお、往路コンベヤ6及び復路コンベヤ7には固定の物品ガイドを利用しない構成としたが、移動物品ガイド11と干渉しない構造で往路コンベヤ6及び復路コンベヤ7の外側に、固定の物品ガイドを設置することが出来る。また、説明において物品搬送手段としてコンベヤチエン17を例示したが、搬送コンベヤは特にチエンに限るものでなくベルト等が利用可能であり、移送装置4は円テーブルとしたがカーブコンベヤをUターンさせて使用しても良く、本発明の主旨の範囲で各種の構成が利用出来る。
【0024】
【発明の効果】
請求項1に記載の発明によれば、物品の先入れ先出し機能を保持して、物品バッファコンベヤ装置前後の物品供給、排出のバランス、アンバランスに対応した物品の滞留数量調整が可能であり、バッファコンベヤ装置前後の機器やコンベヤ上の不具合を吸収してプラントの円滑な稼動を図ることが出来る。また、往路コンベヤ、復路コンベヤ、回転円盤、移送装置における物品搬送速度、並びに転送装置のコンベヤ進行方向の移動速度を個別に駆動して制御出来る為、物品バッファコンベヤ装置の上下流に配置された機器の運転状態、接続コンベヤ上の物品の搬送状態、並びにバッファコンベヤ内部における物品の搬送状況に応じて各装置の運転条件を自由に制御して好適な稼動状態を実現することが出来る。
【0025】
即ち、物品バッファコンベヤ装置の構成機器に対する部分的な無用運転の排除が可能となり、駆動エネルギの節減が可能となるとともに、構成機器の物品移渡し部における物品へのラインプレッシャを減少させて物品の保護を行なう目的や、物品に過大な間隙が発生する時に構成する機器ごと最適な運転条件の設定を行なうことが出来る。また、物品バッファコンベヤ装置の必要部にセンサを設置して、各部の物品搬送状況や不具合を検出して構成機器の速度を自動的に変えてラインプレッシャの低減や物品間の隙間を均一化して物品転倒防止を図ることが可能となり、円滑な物品搬送によるバッファ機能を発揮させる事が出来る。
【0026】
請求項2に記載の発明によれば、請求項1に示す物品バッファコンベヤ装置を平行に複数個設置し、上流側物品バッファコンベヤ装置の復路コンベヤの物品排出部と接続する下流側の往路コンベヤの物品供給端部との間に駆動された移送装置を備えることにより、バッファ装置の容器滞留数量を増加させて、必要に応じたバッファ数量を利用することが出来る。このため、プラントの仕様に適合した物品バッファコンベヤ装置の仕様を指定することが出来る。
【0027】
請求項3に記載の発明によれば、請求項1及び2において、各往路コンベヤ、復路コンベヤをそれぞれ複数のコンベヤに分割して各コンベヤを個別に駆動することにより、バッファ装置を構成する往路コンベヤ、復路コンベヤ等の内、運転が必要な部分のみを運転することが可能となり、従来の装置の如く常に装置全体を駆動する必要が無いため、動力の節減と部品消耗と騒音低減を図ることが出来る。
【0028】
請求項4に記載の発明によれば、物品バッファコンベヤ装置の上、下流側コンベヤ上の物品滞留数量等の搬送状況や物品バッファ装置の内部における物品滞留数量、物品移渡し部の物品の搬送状況等に応じて、バッファ装置の構成要素の駆動速度等を自在に制御してプラントを安定して稼動させることが出来る。
【0029】
請求項5に記載の発明によれば、バッファ装置の上下流コンベヤの物品搬送状況に応じて、搬送する物品を物品バッファコンベヤ装置に導入して、簡易な方法で安定して物品の搬送と滞留数量の調整を図りプラントの安定稼動を実現することが出来る。

[0016]
Hereinafter, the operation and function of each component in the article buffer conveyor device 1 based on the embodiment will be described. In FIG. 1, the articles B supplied from the supply conveyor 2 are supplied to the article buffer conveyor apparatus 1, and are sequentially discharged from the discharge conveyor 3 through the individual buffer apparatuses 1d from the individual buffer apparatuses 1a to the equipment installed downstream. Conveyed. As shown in the drawing, in the case where the articles B stay on the entire surface of the individual buffer device 1d and substantially half of the area of the individual buffer device 1c, when the operation capabilities on the supply side and the discharge side are the same, the article buffer conveyor device 1 Are operated at the same article transfer capacity as this operation capacity. Hereinafter, the operation and function of the article buffer conveyor apparatus 1 in various situations of the plant will be described using the high-speed capacity Vh and the low-speed capacity Vl based on the reference capacity Vk of the plant.
[0017]
In FIG. 1, for example, when the discharge conveyor 3 stops due to a failure of the downstream equipment and the articles B corresponding to the reference capacity Vk are continuously supplied from the supply conveyor 2, the transfer device 5 c of the individual buffer device 1 c sequentially moves to the right in the drawing. And the article B is further retained on the conveyor. At this time, the moving speed of the transfer device 5c is approximately の of the article conveying speed from the supply conveyor to the forward conveyor of the individual buffer device 1c. Further, in this state, the individual buffer device 1d, the transfer device 4c, and the return conveyor 7ca stop driving, and the transport device for the other articles B continues to operate at the reference capacity Vk. Thereafter, when the individual buffer device 1c becomes full, the articles B are sequentially stored in the individual buffer device 1b and the individual buffer device 1a, and the upstream equipment and the supply conveyor 2 are stopped until the individual buffer device 1a becomes full and stops. Driving can be continued.
[0018]
In FIG. 1, when the condition on the downstream side is resolved and the processing of the article B is smoothed and the condition for raising the driving capacity to the reference capacity Vk or more is established, the capacity of the discharge conveyor 3 is increased to the high-speed capacity Vh and the article B is increased. Transport speed can be increased. At this time, the operating speed of the individual buffer devices 1c, 1d and the transfer device 4c is increased to the high-speed capability Vh in conjunction with the discharge conveyor 3. On the other hand, in response to this, the transfer device 5c is sequentially moved to the left in the figure at a predetermined speed, and the difference between the amount of articles supplied from the supply conveyor 2 to the individual buffer device 1c and the amount of discharge from the individual buffer device 1c to the downstream side. The number of articles stored on the individual buffer device 1c is reduced in such a way that
[0019]
Then, after the transfer device 5c of the individual buffer device 1c moves to the left in the drawing and moves to the end position of the movement range, the transfer device 5d of the individual buffer device 1d is moved to the left in the same manner as above to Reduce the amount of stagnation. Thereafter, when the transfer device 5c of the individual buffer device 1d reaches the end position in the left direction in the figure, the operation is performed by returning the operation capability of the downstream device, the discharge conveyor 3, and the buffer conveyor device 1 (not shown) to the reference capability Vk. .
[0020]
In FIG. 1, when the supply of the article B from the supply conveyor 2 is stopped and the discharge conveyor 3 is operating, the individual buffer devices 1a and 1b and the transfer device 4a are stopped and the individual buffer device 1c is stopped. 1d, the excess staying articles B are discharged, each transfer device is returned to the left end in the figure, and the entire article buffer conveyor device 1 is stopped. In this case, depending on the type of the article B and the characteristics of the plant, it is possible to adopt a production method in which the article B in the article buffer conveyor device 1 is discharged as much as possible and the article B is not left.
[0021]
As described above, the operation and function of the article buffer conveyor device 1 according to the present invention as a buffer device have been described with respect to basic operating conditions. However, the operation of the article buffer conveyor device 1 is not particularly limited to the above-described conditions. Instead, various operations can be performed in accordance with the configuration of the plant, the type of the article B to be handled, and the operating conditions within the scope of the present invention. The control of the operating conditions of the article buffer conveyor device 1 is performed by controlling the data on the operation status of the upstream and downstream devices of the article buffer conveyor device 1 and the data on the article transport status of the article sensors 23 and 24 arranged on the supply conveyor 2 and the discharge conveyor 3. And the like are separately processed by a control data processing device (not shown) to control the rotation speed of the drive motor of each unit.
[0022]
In the embodiment, the case where all the articles B to be handled are directly supplied to the article buffer conveyor apparatus 1 has been described. However, when the apparatus is installed as a bypass line with respect to the main stream of the conveyor of the plant and the buffer function is required. It is also possible to introduce or discharge the article B into the buffer apparatus only when the apparatus is used. Although the case where four sets of the individual buffer devices 1a to 1d are used is illustrated, the number of sets of the individual buffer devices can be freely selected according to the buffer capacity required as the buffer device in the plant. Although the individual buffer devices 1a to 1d have been described as linear conveyors, a curved conveyor may be used as necessary to provide a curved portion in a layout, and to respond to a demand for an installation location.
[0023]
Although the fixed article guide is not used for the forward conveyor 6 and the backward conveyor 7, a fixed article guide is provided outside the forward conveyor 6 and the backward conveyor 7 so as not to interfere with the moving article guide 11. I can do it. In the description, the conveyor chain 17 has been exemplified as the article conveying means. However, the conveyor is not limited to the chain, and a belt or the like can be used. The transfer device 4 is a circular table, but the curve conveyor is U-turned. It may be used, and various configurations can be used within the scope of the present invention.
