Description

【発明の属する技術分野】
本発明は、物品を自動で仕分ける仕分け装置における物品供給機構及び物品仕分け機構の位置関係の検出方法に関し、特に、物品を台車に供給する供給機構から物品を払い出す仕分け機構までの距離を自動的に計測することができる仕分け装置における物品供給機構及び物品仕分け機構の位置関係の検出方法に関するものである。
【0002】
【従来の技術】
物品を自動で仕分ける仕分け装置としては、多数の台車を無端連鎖状に接続して構成した搬送台車群を、走行路に沿って循環移動させながら、インダクション等の物品供給機構から各々の台車に物品を供給して搬送するとともに、この物品をシュート等の物品仕分け機構に払い出すようにした仕分け装置が汎用されている。
【0003】
従来、この種の仕分け装置においては、物品の払い出し位置を設定する場合は、物品を供給した位置から払い出す位置までの距離をあらかじめ管理パソコン上で設定し、この間をパルスカウントすることによってタイミングを計り、払い出し動作を起動させる方法が一般的であった。
【0004】
【発明が解決しようとする課題】
しかしながら、上記従来の仕分け装置では、物品の供給位置から払い出し位置までの距離が変更された場合は、その都度、人手により距離を設定する必要があり、非常に手間がかかるという問題があった。
【0005】
本発明は上記従来の仕分け装置が有する問題点に鑑み、物品の供給位置から払い出し位置までの距離の設定を自動的に行うことにより、この距離に変化が生じた場合でも、自動的にその値を検出し、所定の位置に物品を払い出すようにした仕分け装置における物品供給機構及び物品仕分け機構の位置関係の検出方法を提供することを目的とするものである。
【0006】
【課題を解決するための手段】
上記目的を達成するために、本発明の仕分け装置における物品供給機構及び物品仕分け機構の位置関係の検出方法は、多数の台車を無端連鎖状に接続して構成した搬送台車群を、走行路に沿って一方向に循環移動させながら、物品供給機構から各々の台車に物品を供給して搬送するとともに、該物品を物品仕分け機構に払い出すようにした仕分け装置における物品供給機構及び物品仕分け機構の位置関係の検出方法において、特定の台車マーカーからなる被検出体を設けるとともに、各物品供給機構と各物品仕分け機構とに、通過する前記被検出体を検出する検出手段をそれぞれ設け前記被検出体を検出した時間差によって、任意の物品供給機構から物品仕分け機構までの距離を算出し、算出したデータを制御機構に記憶し、制御機構に記憶したデータに対応した位置で物品の供給及び払い出しの動作を行うようにすることを特徴とする。
【0007】
本発明の仕分け装置における物品供給機構及び物品仕分け機構の位置関係の検出方法では、一方向に循環移動する台車群の特定の1台を原点として被検出体を設けるとともに、物品供給機構と物品仕分け機構とに、通過する被検出体を検出する検出手段を設け、この物品供給機構と物品仕分け機構とで生じる被検出体の検出時間差によって、制御機構が物品供給機構から物品仕分け機構までの距離を算出し記憶することができる。
これにより、物品供給機構から物品仕分け機構までの距離を自動計測し、両機構の位置に変化がない場合は、上記計測データを繰り返し読み出し、また、両機構の位置に変化が生じた場合は、被検出体を設けた台車が走行路を1周して、両機構間の距離データを自動修正し、修正データに対応した位置で自動的に供給、払い出し動作を行うことができる。
【0008】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
【0009】
図1に本発明の仕分け装置における物品供給機構及び物品仕分け機構の位置関係の検出方法を適用する仕分け装置の一実施例を示す。
この仕分け装置は、多数の台車1を無端連鎖状に接続して構成した搬送台車群を備え、この搬送台車群を、閉ループの走行路2(本実施例において、走行路2は、一部分が上下に重なって構成されている。)に沿って循環移動(図1に、移動方向を矢印で示す。)させながら、インダクション等の物品供給機構3から各々の台車1に物品(図示省略)を供給して搬送するとともに、この物品をシュート等の物品仕分け機構4に払い出すように構成されている。
【0010】
台車1は、物品を載置するトレー1aを備え、払い出し位置で、このトレー1aをアクチュエータ等によって物品仕分け機構4に傾倒させることにより、物品を払い出すようになっている。
なお、トレー1aの代わりにキャリッジ等を用いることも可能である。
【0011】
ところで、本実施例の仕分け装置においては、特定の1台の台車1にマーカーからなる被検出体5を設けるとともに、各物品供給機構3と各物品仕分け機構4とにそれぞれ、通過する被検出体5を検出する検出手段6、7を設けている。
そして、台車1に設けた被検出体5を検出した時間差によって、任意の物品供給機構3から物品仕分け機構4までの距離を算出し記憶する制御機構(図示省略)を設けている。
【0012】
検出手段6、7は、同じものを使用しており、また、これら検出手段6、7としては、例えば光センサーや超音波センサー等の同じものを使用することができる。
また、被検出体5としては、これらのセンサーに対応する反射板等を使用することができ、例えば、台車1のトレー1aの両側に貼着することができる。
さらに、制御機構としては、パソコン等を使用し得る。
【0013】
しかして、本実施例の仕分け装置では、台車1に取り付けた被検出体5は、物品供給機構3による供給位置を通過する瞬間に検出され、その時間が制御機構に記憶される。
また、被検出体5は、物品仕分け機構4の払い出し位置(例えばトレー傾倒装置の位置)を通過する瞬間に検出され、その時間が制御機構に記憶される。
すなわち、上記制御機構では、物品供給機構3と物品仕分け機構4とで生じる被検出体5の検出時間差によって、物品供給機構3から物品仕分け機構4までの距離を計算し、例えば、これを台車1の進行方向のパルスに換算して記憶する。
【0014】
そして、物品供給機構3と物品仕分け機構4の位置に変化がない場合は、上記計測データを繰り返し読み出して、正確に再現し、データに対応した位置で自動的に供給、払い出し動作を行うことができる。
また、物品供給機構3と物品仕分け機構4の位置に変化が生じた場合は、被検出体5を設けた台車1が走行路2を1周して、両機構間の距離データを自動修正し、修正データに対応した位置で自動的に供給、払い出し動作を行うことができる。
【0015】
【発明の効果】
本発明の仕分け装置における物品供給機構及び物品仕分け機構の位置関係の検出方法によれば、一方向に循環移動する台車群の特定の1台を原点として被検出体を設けるとともに、物品供給機構と物品仕分け機構とに、通過する被検出体を検出する検出手段を設け、この物品供給機構と物品仕分け機構とで生じる被検出体の検出時間差によって、制御機構が物品供給機構から物品仕分け機構までの距離を算出し記憶することが可能であり、これにより、物品供給機構から物品仕分け機構までの距離を自動計測し、両機構の位置に変化がない場合は、上記計測データを繰り返し読み出し、また、両機構の位置に変化が生じた場合は、被検出体を設けた台車が走行路を1周して、両機構間の距離データを自動修正し、修正データに対応した位置で自動的に供給、払い出し動作を行うことができる。

Articles (not shown) are supplied to each carriage 1 from the article supply mechanism 3 such as induction while being circularly moved along the direction (indicated by arrows in FIG. 1). The article is conveyed and delivered to the article sorting mechanism 4 such as a chute.
[0010]
The cart 1 is provided with a tray 1a on which articles are placed, and the articles are dispensed by tilting the tray 1a to the article sorting mechanism 4 by an actuator or the like at the dispensing position.
A carriage or the like can be used instead of the tray 1a.
[0011]
By the way, in the sorting apparatus of the present embodiment, the detected object 5 made of a marker is provided on one specific carriage 1, and the detected objects that pass through each of the article supply mechanisms 3 and each of the article sorting mechanisms 4, respectively. Detection means 6 and 7 for detecting 5 are provided.
And the control mechanism (illustration omitted) which calculates and memorize | stores the distance from the arbitrary goods supply mechanism 3 to the goods sorting mechanism 4 with the time difference which detected the to-be-detected body 5 provided in the trolley | bogie 1 is provided.
[0012]
The same detection means 6 and 7 are used, and the same detection means 6 and 7 such as an optical sensor and an ultrasonic sensor can be used.
Moreover, as the detection object 5, a reflecting plate or the like corresponding to these sensors can be used. For example, it can be attached to both sides of the tray 1a of the carriage 1.
Furthermore, a personal computer etc. can be used as a control mechanism.
[0013]
Thus, in the sorting apparatus according to the present embodiment, the detected object 5 attached to the carriage 1 is detected at the moment when it passes the supply position by the article supply mechanism 3, and the time is stored in the control mechanism.
The detected object 5 is detected at the moment when it passes through the dispensing position of the article sorting mechanism 4 (for example, the position of the tray tilting device), and the time is stored in the control mechanism.
That is, the control mechanism calculates the distance from the article supply mechanism 3 to the article sorting mechanism 4 based on the detection time difference of the detected object 5 generated by the article supply mechanism 3 and the article sorting mechanism 4. It is converted into a pulse in the traveling direction and stored.
[0014]
When there is no change in the positions of the article supply mechanism 3 and the article sorting mechanism 4, the measurement data is repeatedly read out, accurately reproduced, and automatically supplied and dispensed at positions corresponding to the data. it can.
Further, when a change occurs in the positions of the article supply mechanism 3 and the article sorting mechanism 4, the carriage 1 provided with the detected body 5 makes one round of the traveling path 2 and automatically corrects the distance data between the two mechanisms. , Supply and payout operations can be automatically performed at positions corresponding to the correction data.
[0015]
【The invention's effect】
