この発明は、ベルトコンベア上の輸送物の有無検知方法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for detecting the presence or absence of an object to be transported on a belt conveyor.
従来、ベルトコンベア上の輸送物の有無は、第2図に示
すように、ベルトコンベア1の上方部に設けられた輸送
物有無検出器2により行っていた。Conventionally, the presence or absence of a transported object on a belt conveyor has been determined by a transported object presence/absence detector 2 provided at an upper portion of the belt conveyor 1, as shown in FIG.
輸送物有無検出器2は、ベルトコンベア1上の輸送物3
と接触して回動ずる,水平バー5に固定された検出板4
と、検出板4に取り付けられたスイッチ6とからなって
おり、輸送物3との接触による検出板4の動きを、スイ
ッチ6によって検出し、これによって、ベルトコンベア
上の輸送物3の有無を検出していた。The transported object presence/absence detector 2 detects the transported object 3 on the belt conveyor 1.
A detection plate 4 fixed to a horizontal bar 5 rotates in contact with the
and a switch 6 attached to the detection plate 4. The switch 6 detects the movement of the detection plate 4 due to contact with the transported object 3, and thereby detects the presence or absence of the transported object 3 on the belt conveyor. was detected.
しかしながら、上述した従来法は、次のような問題を有
していた。However, the above-mentioned conventional method had the following problems.
(1)輸送物3の層厚が薄い場合には、検出板4が回動
せず、輸送物3の検出が行えない。(1) When the layer thickness of the transported object 3 is thin, the detection plate 4 does not rotate and the transported object 3 cannot be detected.
(2)検出板4は、輸送物3と長時間接触するので、輸
送物3がコークス等の硬いものであると検出板4の磨耗
が激しい。(2) Since the detection plate 4 is in contact with the transported object 3 for a long time, if the transported object 3 is hard such as coke, the detection plate 4 will be severely worn.
(3)検出板4と接触によって 、輸送物3がべルトコ
ンベア1から落下する。(3) Upon contact with the detection plate 4, the transported object 3 falls from the belt conveyor 1.
(4)検出板4が輸送物3に接触したときの衝撃によっ
て、輸送物有無検出器2が破損する虞れがあった。(4) There was a risk that the transported object presence/absence detector 2 would be damaged by the impact when the detection plate 4 came into contact with the transported object 3.
従って、この発明の目的は、輸送物の層厚に関係無く輸
送物の有無の検出が行え、しかも、輸送物の落下や輸送
物による破損の虞れが無い、ヘルトコンベア上の輸送物
の有無検知方法を提供するものである。Therefore, an object of the present invention is to detect the presence or absence of a transported object on a heel conveyor, which can detect the presence or absence of a transported object regardless of the layer thickness of the transported object, and without the risk of the transported object falling or being damaged by the transported object. The present invention provides a detection method.
この発明は、ベルトコンベアの輸送物の荷重による撓み
を検出し、これによって、ベルトコンベア上の輸送物の
有無を、輸送物と非接触で検知することに特徴を有する
ものである。The present invention is characterized in that the deflection of the belt conveyor due to the load of the transported object is detected, thereby detecting the presence or absence of the transported object on the belt conveyor without contacting the transported object.
この発明のベルトコンベア上の輸送物の有無検知方法を
、図面を参照しながら説明する。A method for detecting the presence or absence of a transported object on a belt conveyor according to the present invention will be explained with reference to the drawings.
第1図は、この発明の、ベルトコンベア上の輸送物の有
無検知方法の一実施態様を示す正面図である。FIG. 1 is a front view showing an embodiment of the method for detecting the presence or absence of a transported object on a belt conveyor according to the present invention.
第1図に示すように、この発明は、ベルトコンヘア1上
の輸送物3の荷重による撓みを、ベルトコンベア1の下
方部に設けた荷重検出器7により検出し、これによって
、ベルトコンベアl上の輸送物3の有無を非接触で検知
するもである。As shown in FIG. 1, the present invention detects the deflection of the transported object 3 on the belt conveyor 1 by the load detector 7 provided at the lower part of the belt conveyor 1. The presence or absence of the transported object 3 above is detected in a non-contact manner.
荷重検出器7は、一端が軸支されたアーム8と、アーム
8に取り付けられた、ベルトコンベア1の下面と接触し
て回転するローラー9と、アーム8の他端に設けられた
スイッ10とからなっている。The load detector 7 includes an arm 8 whose one end is pivotally supported, a roller 9 attached to the arm 8 that rotates in contact with the lower surface of the belt conveyor 1, and a switch 10 provided at the other end of the arm 8. It consists of
ベルトコンベア1上の輸送物3の荷重によりベルトコン
ベア1が下方に撓むと、ベルトコンベア1の下面と接触
して回転するローラー9を介してアーム8が押し下げら
れる。これによってスイッチ10がオンして、ベルトコ
ンベア1上に輸送物3が乗っていることが検知される。When the belt conveyor 1 is bent downward due to the load of the transported object 3 on the belt conveyor 1, the arm 8 is pushed down via the roller 9 that rotates in contact with the lower surface of the belt conveyor 1. As a result, the switch 10 is turned on, and it is detected that the transported article 3 is placed on the belt conveyor 1.
なお、荷重検出器の代わりに、スリップ検出器を用いて
もよい。Note that a slip detector may be used instead of the load detector.
以上説明したように、この発明によれば、ベルトコンベ

の層厚に関係無く輸送物の有無の検出が行え、しかも、
輸送物と接触するものがないので、輸送物の落下や荷重
検出器の破損の虞れはないといった有用な効果がもたら
される。As explained above, according to the present invention, the presence or absence of the transported object on the bell 1 conveyor is detected by the deflection of the belt conveyor due to the transported object, so it is not necessary to detect the presence or absence of the transported object on the belt 1 conveyor, regardless of the layer thickness of the transported object, as in the conventional case. It is possible to detect the presence or absence of transported objects, and
Since there is nothing that comes into contact with the transported object, there is no risk of the transported object falling or damage to the load detector, which is a useful effect.
