Embodiment 1

[0024] see figure 1 The flowchart of this specific embodiment discloses a batching control method, and the batching is controlled through the following steps:

[0025] Step 1. The input device on the control system inputs the batching amount of each material storage component for each storage tank of the material; feasible, for example, each storage tank may correspond to a setting component for setting the batching amount, including The adjustment button and the liquid crystal display screen have a controller for the entire control panel inside, which is connected with the control system, and the setting data is stored in the memory of the control system.

[0026] Step 2. Calibrate the electronic weighing device in the electronic weighing tank at the outlet of each storage tank and the electronic weighing device in the precise weighing tank. At this time, the calibration adopts the zero-return calibration in the electronic weighing device , Feasible, the electronic weighing ...

Embodiment 2

[0038] see figure 2 , this specific embodiment discloses a batching system applying the batching control method in Example 1, including a weighing system, a precision system, a control system and a mixing conveyor, and a switch is used between the weighing system and the precision system The valve is connected, the weighing system and the precision system are respectively connected to the mixing conveyor through the switch valve, the weighing system and the precision system are respectively electrically connected to and controlled by the control system, and the feeding part of the weighing system is respectively connected through the large and small The feeding valve feeds the material, and the switching speed of the large feeding valve is controlled by the control system. In addition, the weighing system and precision system can also be connected to the return bin through the switch valve, which is used to return the material whose weighing exceeds the range to the storage t...

Abstract

The invention discloses a material preparing control method. According to the method, material discharge and primary weighing are performed, a program closes a material discharge valve when a materialpreparing amount preset value is approached so as to achieve the precise control of the material discharge amount, and the closing speed of a switch valve is controlled through sampling precise weighing statistical analysis so as to improve the precision of the weighing, such that the proportion of the process comprising repeated valve closing and then weighing can be reduced. According to the present invention, with the method and the system, the material discharge process at a weighting preset amount approaching point is controlled by controlling the closing speed of the switch valve so asto substantially reduce the weighing time and improve the material preparing efficiency; the precise weighing is performed through interval sampling, and the opening/closing speed is adjusted according to the statistical result, such that the opening/closing speed of the switch valve can be automatically adjusted; and the material preparing precision is gradually adjusted according to the statistical result so as to substantially reduce the repeated material discharging and weighing processes in the weighing process, such that the proportion of the one-time weighing meeting the error requirement can be increased, and the material preparing efficiency is improved.

Description

technical field [0001] The invention relates to batching equipment, in particular to a batching control method and system. Background technique [0002] The batching process is used in the processing of food processing, chemical batching and other fields, and batching is required. The traditional batching process uses manual batching methods for batching. In the prior art, automatic batching equipment is used for batching, and electromagnetic batching is usually used. The valve controls the feeding and weighs through the electronic scale, and the PLC continuously circulates the judgment until the preset weighing material is reached. This method requires repeated opening and closing of the discharge valve, and a large number of judgments and weighing processes are required, which consumes more Time, resulting in extremely low batching efficiency. For example, the Chinese Patent Publication No. CN107442033A discloses a batching control method and a batching device, which spec...
