Problems solved by technology

[0009] 1. The number of hollow intervals (six) of the code collector does not match the number of hoppers (eight in each row) of the rotary hopper, resulting in unbalanced weights of the put materials corresponding to the six pulse signals corresponding to one rotation, and uneven Conducive to the control of weighing accuracy;
[0010] 2. The matching algorithm of the program control system is not accurate, but only a rough estimate;
[0011] 3. The program system rounds the calculated weight value of the material for control and output display, thus increasing the weighing error

Embodiment Construction

[0038] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0039] see Figure 4 , Figure 5 Shown, the concrete steps of rotary feeder weighing control method of the present invention are as follows:

[0040] A. Rotate feeding by controlling the rotating bin by the motor;

[0041] B. Design a coded collector whose number of hollow space intervals matches the number of buckets of the rotating silo, install it on the bottom of the rotating silo and rotate together with the rotating silo;

[0042] C. Count the code collector through the code counter and output the detected pulse signal to the PLC;

[0043] D. Establish a calculation model in the PLC, and calculate the actual weight of the feeding material according to the pulse signal, and control the switch of the motor by comparing it with the weight set value.

[0044] combine Figure 6 As shown, for the mismatch defect of the nu...

Abstract

The invention discloses a weighing control method of rotary feeders. The control method comprises the steps of matching the number of hollow-out intervals of an encoder acquirer with the number of material funnels of a rotary material cabin, optimizing the calculation model of a practical weight value of the fed material, setting a precision error, and comparing the results with a setup weight value so as to carry out real time control on a motor switch. With the adoption of the control method, the weighing precision is improved effectively, thereby realizing accurate feeding.

Description

technical field [0001] The invention relates to automatic feeding metering technology, more specifically, relates to a weighing control method of a rotary feeder. Background technique [0002] Automatic feeding systems have been widely used in various industries. Taking the metallurgical industry as an example, in order to obtain high-performance alloys, when feeding, the materials are added from the feeding system to the high-level silo, and then weighed according to the required weight through the weighing hopper, and then put in. In this process, the key to accurate control of the added weight of various materials is the weighing control of the weighing hopper. The existing weighing control generally adopts multi-sensor or rotary feeder control. Among them, the main structure of the rotary feeder is as follows: Figure 1 ~ Figure 3 As shown, the rotary silo 1 contains sixteen hoppers 2, eight in each row, and the two rows are misplaced with each other; the code collecto...
