産業上の利用分野
本発明は包装貨物を落下させて試験する落下試験装置に
関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a drop testing device for testing packaged cargo by dropping it.
従来の技術
一般に包装設計を効果的に進めるためには、包装貨物試
験を実施する必要がある。特に落下試験は顕度も高く、
また重要な試験項目であって、そのだめには、精度が高
く、操作性に優れた落下試験装置が要望されていた。BACKGROUND OF THE INVENTION In general, in order to effectively proceed with packaging design, it is necessary to conduct packaging cargo testing. In particular, the drop test is highly sensitive.
This is also an important test item, and there was a need for a drop test device with high accuracy and excellent operability.
このようなことから、従来の落下試験装置はたとえば第

アーム４はアーム主軸８を中心として回転運動し包装貨
物７は落下基板２上に落下するようにしている。For this reason, conventional drop testing equipment has utilized a simple drop testing machine using an arm, as shown in FIG. 3, for example. That is, in this simple drop tester, an arm 4 is set at an appropriate height position on a support 3 erected on a floor 1, and a bed 5 for secting packaged cargo 7 is connected to the tip of this arm 4. ing. In the dropping operation, by pushing the drop lever 6, the built-in arm rest and the retracting arm 4 are rotated about the arm main shaft 8, and the packaged cargo 7 is dropped onto the dropping board 2.
発明が解決しようとする問題点
前記動作を第４図により説明すると、アーム４がアーム

ットした包装貨物７は斜傾した状態にて自然落下する訳
である。Problems to be Solved by the Invention The above operation will be explained with reference to FIG. 4. When the arm 4 starts to rotate around the arm main shaft 8, the bed tip 9 and the bed front part 1Q of the bed 5 fixed to the arm 4 , the moving distance is different, that is, the distance that the bed tip part 9 moves is greater than the bed front part 1o, and the bed 6
is in a tilted state. Therefore, the packaged cargo 7 set on the entire ped 5 naturally falls in an inclined state.
特に、包装貨物の面落下を行なう場合、このことが原因
となシ、床面に対し傾斜した状態で包装貨物が落下する
ため（以下傾斜面落下と称す）、水平状態で落下した（
以下水平面落下と称す）場合に比べ、包装貨物７に発生
する衝撃加速度は、傾斜面落下の方が小さくなる。また
、傾斜面落下は包装貨物７の重量９寸法によっても変化
するため（実験結果より）、包装貨物毎に、試験実施毎
に発生する衝撃加速度がバラツクといった問題があり、
試験の精度は低い訳であった。In particular, when packaging cargo is dropped on a flat surface, this is not the cause, as the packaged cargo falls in an inclined state with respect to the floor (hereinafter referred to as "sloped surface dropping"), so it may fall horizontally (
The impact acceleration generated on the packaged cargo 7 is smaller when the packaged cargo 7 is dropped on an inclined surface than when the packaged cargo 7 is dropped on an inclined surface. In addition, since the slope drop also changes depending on the weight and dimensions of the packaged cargo 7 (according to experimental results), there is a problem that the impact acceleration that occurs each time the test is carried out varies for each packaged cargo.
The accuracy of the test was low.
本発明は上記従来の問題に留意し、包装貨物を水平面落
下することができる包装貨物落下試験装置を提供するこ
とにある。The present invention takes into consideration the above-mentioned conventional problems and provides a packaged cargo drop test device that can drop packaged cargo on a horizontal surface.
すため、前記ベッド先端部側の包装貨物の側面に当接す
