Claims (1)

[Claims for Utility Model Registration] (1) A raw material supply capable of shaking out and discharging raw materials in the container by vibrating a container containing chip-shaped raw materials and adjusting the average amount of raw materials discharged per unit time. a conveyance path for conveying the raw material from the raw material supply means; and a conveyance control means for controlling the conveyance speed of the conveyance path by measuring the weight of the conveyed object in a certain section of the conveyance path with a weighing machine. In the conveyance device, a hopper is provided below the discharge port of the raw material supply means to temporarily store the raw material discharged from the raw material supply means and supplies the raw material from the lower discharge port to the conveyance path; height detecting means for detecting whether the accumulated height of the raw material is within a preset height range; and a supply amount for adjusting the discharge amount of the raw material supplying means according to the detection state of the height detecting means. control means, the supply amount control means reduces the discharge amount of the raw material supply means when the accumulation height in the hopper exceeds the height range, and the supply amount control means reduces the discharge amount of the raw material supply means when the accumulation height in the hopper exceeds the height range. 1. A raw material conveying device, characterized in that the raw material conveying device is controlled so as to increase the discharge amount of the raw material supply means when the raw material supply means rotates. (2) The raw material supply means includes a spiral conveying trough provided along the inner wall of a cylindrical container, and conveys the raw material by vibrating the cylindrical container and raising the raw material on the conveying trough. 2. The material conveying device according to claim 1, characterized in that it is a spiral vibrating conveyor adapted to discharge from the upper end of the trough. (3) The height detecting means detects that the raw material in the hopper blocks/transmits detection light from photoelectric devices provided at upper and lower positions on the inner surface of the hopper, and determines the accumulated height. 3. The raw material conveying apparatus according to claim 1, wherein the raw material conveying apparatus is adapted to detect the degree of the raw material conveyance.
