Title:
APPARATUS FOR CONTINUOUSLY MEASURING BULKY MATERIAL SUCH AS CUT TOBACCO
Document Type and Number:
Japanese Patent JPS5982075
Kind Code:
A
Abstract:
An apparatus is provided for the continuous measurement of the bulk density of particulate material comprising an endless belt weighing conveyor having a compression zone and a weigh span downstream of the compression zone, means for feeding the material to said compression zone, a compression unit at said compression zone having a series of rollers an axes extending transverse to the direction of movement of the weighing conveyor, and transducer means provided at the weigh span for producing signals proportional to material weight. The rollers may be driven with a surface speed equal to the weighing conveyor belt speed and additional rollers may be mounted below the weighing conveyor to carry the load. The rollers are preferably embraced by a belt which gives a continuous surface and prevents tobacco getting between the rollers. In which case, the belt is driven with the same speed as the weighing conveyor belt, via a terminal roller and the other rollers follow.
