    • PROBLEM TO BE SOLVED: To prevent a material in a weighing pan region from passing through a hole, which is formed in a barrier between the weighing pan region and a weighing mechanism region, into the weighing mechanism region.SOLUTION: A weighing apparatus comprising a weighing pan 42 for supporting on an upper surface thereof an object 21 to be weighed, an elongate member 23 connected to the weighing pan and extending downwardly therefrom, a barrier formed between a weighing pan region and a weighing mechanism region, and a weighing mechanism 44 to which the elongate member is connected, the elongate member 23 extending through a hole 24 provided in a floor 36, which is the barrier, in the weighing pan region of the apparatus, the weighing mechanism being located in the weighing mechanism region beneath the floor, comprises drive means 28 for selectively directing and moving the elongate member and the weighing pan to a lower position which establishes a sealing relationship between an upper position at which the weighing pan is spaced from the floor, and the lower position at which at least one of the weighing pan and the elongate member contacts the floor, in order to prevent a material in the weighing pan region from passing through the hole into the weighing mechanism region.
    • 要解决的问题:为了防止称重盘区域中的材料通过形成在称重盘区域和称重机构区域之间的隔板中的孔进入称重机构区域。 解决方案:一种称重设备,包括用于在其上表面上支撑待称重的物体21的称重盘42,连接到称重盘并从其向下延伸的细长构件23,形成在称重盘区域和 称重机构区域和称重机构44,细长构件连接到其上,细长构件23延伸穿过设置在装置的称重盘区域中的作为阻挡物的地板36中的孔24,称重机构 位于地板下方的称重机构区域中,包括用于选择性地将细长构件和称重盘引导并移动到下部位置的驱动装置28,该下部位置在称重盘与地板间隔开的上部位置之间形成密封关系 ,以及称重盘和细长构件中的至少一个与底板接触的下部位置,以防止称重的材料 g盘区域从穿过孔进入称重机构区域。 版权所有(C)2012,JPO&INPIT
