Embodiment 1

[0041] Such as figure 1 As shown, the method of speeding up the feeding speed of the electromagnetic chuck includes:

[0042] 1) Full disk loading: According to the set batching parameters, the electromagnetic chuck walks to the raw material area, absorbs the raw materials with full excitation voltage, and moves to the safe walking position;

[0043] 2) Batching judgment: If the suction amount of the raw material absorbed by the current tray exceeds the remaining weight and tolerance of the raw material, it will enter the final tray batching. At this time, the batching amount is the remaining weight of the raw material, otherwise the normal full tray is filled ;

[0044] 3) The last plate ingredient: load the variable used to control the amount of material absorbed by the electromagnetic chuck, and set the state of the electromagnetic chuck to Busy (1) in the task, and use the variable of the amount of material absorbed by the electromagnetic chuck to control and adjust the e...

Abstract

A method for increasing the ingredient adding speed of an electromagnetic chuck is provided. The amount of raw materials sucked by the electromagnetic chuck is controlled and adjusted by setting variables used for controlling the electromagnetic chuck to configure the material suction amount of the last chuck of raw materials in a control system of the electromagnetic chuck, and the variables of the material suction amount comprise the ingredient amount, the tolerance amount and the redundancy amount; in order to better control discharging of the last chuck of materials of the electromagnetic chuck, the ingredient amount, the tolerance amount and the redundancy amount form four compound variables used for controlling discharging through the following operation; and the composite variables are [ingredient amount + tolerance amount + redundancy amount], [ingredient amount + tolerance amount], [ingredient amount] and [ingredient amount-tolerance amount]. According to the technical scheme, when the electromagnetic chuck sucks the last chuck of raw materials, the weight of the sucked raw materials can be directly positioned to be close to the weight of the ingredients, and the weight of the materials needing to be added can be obtained after stabilization of two vibration periods.

Description

technical field [0001] The invention relates to the technical field of electrical control, in particular to the technical field of batching control applied in the foundry industry. Background technique [0002] In the feeding process of the smelting factory in the foundry industry, the method of driving and electromagnetic chuck is often used to suck out the magnetic raw material from the material pit as needed, and transfer it to the furnace mouth of the melting furnace, or to the hearth transfer car corresponding to the furnace mouth of the melting furnace. [0003] Among them, taking the longest time mode of the control loop as an example, the conventional electromagnetic chuck related electrical data PLC controller switching delay <= 15ms; intermediate relay <= 25ms; other <= 60ms; that is, within 100ms, the excitation will be established . When the remaining weight of each batching is greater than the capacity of the tray, it will walk directly after absorbing...
