ミングを決定するものであり、この点に制御の困
難性が生じている。 Conventionally, a level switch with two level detection functions, full and empty, was installed in each material supply hopper installed on the top of the measuring device, and depending on the signal from this level switch, the level switch was installed as needed each time. Some devices are configured to perform material replenishment. However, with this kind of configuration, there is no effective way to deal with the situation when empty signals are issued from multiple material supply hoppers at the same time. It had to be large-capacity (e.g., 8 m 3 capacity compared to the required 1 m 3 ). We attempted to solve this problem by issuing a preliminary signal from the level switch when the remaining amount was relatively large and supplying the material to maintain it at a safe level at all times (Japanese Unexamined Patent Application Publication No. 1983-1999).
No. 24403), but since it is required to detect and confirm the required amount of replenishment each time, the control system becomes complicated and the capacity of the material supply hopper becomes large. In any case, these configurations determine the replenishment amount and replenishment timing depending on the fluctuating remaining amount in the material supply hopper, and this makes control difficult.

を有している。 In view of the above circumstances, the present invention aims to provide a material supply control device in a batcher plant that can replenish an appropriate amount of material at an appropriate timing and reduce the capacity of a material supply hopper.
Instead of relying on the fluctuating remaining amount in the material supply hopper, material supply control is performed based on the set measurement value of each material in the measuring device. For this reason, the material supply control device according to the present invention includes a calculation means for calculating the supply gate opening time of each material storage tank necessary for replenishing the corresponding material based on the set measurement value of each material, and each A detection means detects the height of the material level in the material supply hopper, and when it is determined that the material level is high based on a signal from the detection means, the calculation result of the calculation means is used to calculate the supply gate opening time. a correction means for correcting the calculation result of the calculation means in the direction of increasing the supply gate opening time when the material level is determined to be low; Based on the correction result of the correction means, the apparatus includes means for correcting the opening/closing time of the supply gate of each material storage tank and controlling the movement of the distributor.
