Title: Discriminating device of gravel/sand in conveying device of concrete aggregate
Inventor: YOSHINO JUNZO
IPC: B28C7/04
Filed: 1994-08-24
Abstract: PURPOSE: To prevent gravel or sand from being stored errorneously in an improper reservoir tank reliably, moreover, improve durability and simplify structure, by a method wherein discrimination between the gravel or sand is performed easily or highly precisely and reliablity is improved. CONSTITUTION: A vibration detector 17 is fitted to a head chute 6. Since a side wall of the chute 6 is vibrated when aggregate to be transferred from the first transport belt conveyor 3 collides with the head chute, the vibration detector 17 is constituted so that a vibration of the side wall is detected by the detector 17. Then gravel or sand are discriminated from each other by making use of a fact that sizes of vibrations of the side wall are different from each other between a case in which the aggregate to be transported is gravel having comparatively large mass and a case in which the aggregate to be transported is sand having comparatively small mass and when a discrimination result is different from transportation instructions, actions of conveyors 3, 7, 8 are suspended.

Filed: 1992-07-27
Abstract: PURPOSE:To decrease the friction between each bearing part and a body under test and to decrease signal noises by applying a voltage, which offsets the induced voltage caused by the friction between each bearing part and the body under test. CONSTITUTION:Right and left bearing parts 4 and 5 are insulated from the main part of a frame 1 with an insulator I. Offset-voltage generating circuits 11 and 12, which generate the voltage for offsetting the voltage induced by the friction in rotation of a body under test W, are connected between the bearing parts 4 and 5 and the body under test W. The circuits 11 and 12 offset the static electricity generated by the friction between the body under test W and the bearing parts 4 and 5 when the body under test W is rotated and have the measuring circuit for the induced voltage and the generating and feedback controlling circuit for the offset voltage. The dynamic friction coefficient between the bearing parts 4 and 5 and the body under test W is decreased by the offset of the voltages. The noises caused by the friction are alleviated by the outputs of pickups 6 and 7. The accuracy of the measured value of the unbalance is improved with a dynamic-balance measuring circuit 9.
