Title:
LOAD CELL AND METERING MACHINE USING THE LOAD CELL
Document Type and Number:
Japanese Patent JP3182592
Kind Code:
B2
Abstract:
PURPOSE: To solve the shortcoming that ideal fixing of vibration beam type force sensor which should usually cause force only in the direction perpendicular to the fixing plane, causes in most case, force in parallel direction and gives adverse effects to performance.
CONSTITUTION: A load cell for a metering machine has a vibration type force sensor and the both ends of the sensor are fixed respectively to support ends of the load cell. Each end of the sensor is fixed so as to be pushed to the support part by headed bolts 40. The bolt 40 has a screw part at a distant part from the head 41 to fit a nut causing tension force in the bolt. The noncircular cross section part has at least a cross sectional dimension larger than the cross sectional dimension of the screw part 43. The noncircular cross section part of the bolt is forcedly inserted in a hole with smaller dimension than the cross sectional dimension formed in the support part. By this, the generation of force parallel to the fixing part plane can be suppressed.
