Description

Technical Field

[0001] This application relates to the field of roller conveyor control technology, and in particular to a lifting roller conveyor control system and control method, electronic equipment, and storage medium. Background Technology

[0002] When each set of rollers rotates, the frequency converter module controls the rotation of each set of rollers to start and stop simultaneously. During the process of the flame cutting machine cutting the steel billet, the laser rangefinder calculates the position of the steel billet based on the length of the steel billet and the distance between the rangefinders, determines the cutting position of the flame cutting machine's cutting gun, presses down the pressure head, and locks the rollers. At the same time, the flame cutting machine sends the cutting progress signal and the upgrading roller descent signal to the roller control program through program communication. After receiving the upgrading roller descent signal, the roller sends the signal to the corresponding lifting roller valve solenoid valve to control the roller to descend and stop when it reaches the desired position. However, when cutting the steel billet, a large amount of steel slag is generated and accumulates on the lifting roller. The lifting roller at the position of the cutting gun only performs the descent function, resulting in a large amount of molten steel slag accumulating on the descending roller, causing the roller to be uneven. It takes a long time to remove the slag. In addition, the flame cutting of a steel billet takes a long time, and the flame is in contact with the roller for a long time, causing pits on the roller surface and accelerating the deterioration of the roller.

The electronic components in the lifting roller conveyor control system can be housed in a control box; these electronic components include, but are not limited to, contactor modules and relay modules.

[0037] Please see Figure 5 , Figure 5 A schematic flowchart of a control method for a lifting roller conveyor system according to an embodiment of this application is shown. Figure 5 As shown, in an exemplary embodiment, the control method of the lifting roller conveyor control system includes at least steps S510 to S540, which are described in detail below:

[0038] Step S510: Obtain the cutting progress signal of the fire cutting machine and the lower limit signal of the target roller conveyor.

[0039] The cutting signal is continuously received during the billet cutting operation.

[0040] In one embodiment of this application, the target roller conveyor is a separately controlled roller conveyor corresponding to the cutting position of the flame cutter. The flame cutter is controlled by a cutting signal during billet cutting operations; the cutting signal is output by the flame cutter to the target roller conveyor via a communication module.

[0041] In one embodiment of this application, before acquiring the cutting progress signal of the fire cutter and the lower limit signal of the target roller conveyor, the control method of the lifting roller conveyor control system further includes: acquiring the lowering signal of the target roller conveyor; controlling the lowering of the target roller conveyor according to the lowering signal; if the target roller conveyor has already lowered to the lower limit position, activating the target lowering proximity switch in the proximity switch module, and generating the lower limit signal of the lifting roller conveyor through the programmable logic controller.

[0042] In one embodiment of this application, the lowering signal of the lifting roller conveyor is sent by the fire-cutting machine to the lowering solenoid valve via a communication module. After receiving the lowering signal of the lifting roller conveyor via the communication module, the programmable logic controller controls the lowering solenoid valve by controlling the connection of the lowering relay and the lowering wet contact, so as to realize the lowering of the target roller conveyor.

[0043] In one embodiment of this application, a pre-set first time period for the descent signal of the lifting roller conveyor and a cutting proceed signal are used to control the descent of the target roller conveyor to the lower limit position. The pre-set first time period includes, but is not limited to, 10 seconds. The descent control of the target roller conveyor is achieved by the engagement of a descent solenoid valve. The target roller conveyor is determined to have descended to the lower limit position by the activation of a target descent proximity switch, and a lower limit signal of the lifting roller conveyor is generated by the digital input module in the programmable logic controller based on the activation of the target descent proximity switch.

[0044] Step S520: Connect the first electrical path based on the lower limit signal of the lifting roller conveyor.

[0045] The first electrical path is composed of a programmable logic controller in the relay dry contact module, a target dry contact, a target contactor, and a target relay in the relay module.

[0046] In one embodiment of this application, the digital output module in the programmable logic controller outputs the lower limit signal of the lifting roller conveyor to the target relay. The coil of the target relay is energized, the target dry contact is closed, thereby energizing the coil of the target contactor, closing the auxiliary contact of the target contactor, and energizing the target contactor.

[0047] In step S530, if the target contactor is turned on, a closing signal for the lifting roller conveyor is generated by the programmable logic controller.

[0048] In one embodiment of this application, a closing signal for the lifting roller conveyor is generated based on the activation of the target contactor by a digital input module in a programmable logic controller.

[0049] Step S540: Control the rotation of the target roller conveyor according to the closing signal of the lifting roller conveyor, the cutting progress signal and the lower limit signal of the lifting roller conveyor, so as to clean up the steel slag generated and accumulated on the target roller conveyor during the billet cutting operation.

[0050] In one embodiment of this application, the closing signal of the lifting roller conveyor is transmitted to the frequency converter module through the communication module, so that the frequency converter module is in the enabled state, and the target roller conveyor is rotated based on the cutting signal and the lower limit signal of the lifting roller conveyor.

[0051] In one embodiment of this application, after controlling the rotation of the target roller conveyor based on the lifting roller conveyor closing signal, the cutting progress signal, and the lifting roller conveyor lower limit signal, the control method of the lifting roller conveyor control system further includes: acquiring the cutting completion signal and the cutting head lifting signal of the fire cutting machine; disconnecting the target contactor based on the cutting completion signal and stopping the generation of the lifting roller conveyor closing signal; if the lifting roller conveyor closing signal is not generated, generating the lifting roller conveyor rising signal based on the cutting completion signal and the cutting head lifting signal of the fire cutting machine; controlling the target roller conveyor to rise based on the lifting roller conveyor rising signal; if the target roller conveyor has risen to the upper limit position, activating the target rising proximity switch in the proximity switch module and generating the lifting roller conveyor upper limit signal through the programmable logic controller; determining the working state of the target roller conveyor as a waiting-to-start state based on the lifting roller conveyor upper limit signal; if the working state of a set of initial lifting roller conveyors is a waiting-to-start state, determining the cutting state of the billet cutting operation as completed.

[0052] In one embodiment of this application, the cutting completion signal is sent by the fire-cutting machine to the frequency converter module via the communication module, causing the frequency converter module to be in an enabled-disabled state, the target contactor to open, and thus stopping the generation of the lifting roller conveyor closing signal. The digital input module generates a lifting roller conveyor rising signal based on the cutting completion signal and the fire-cutting machine pressure head lifting signal. The digital output module controls the rising solenoid valve by controlling the connection of the lowering relay and the lowering wet contact according to the lifting roller conveyor rising signal for a continuously preset second time period, so as to realize the rising of the target roller conveyor. The preset second time period includes, but is not limited to, 10 seconds.

[0053] In one embodiment of this application, after the billet is cut, the target roller conveyor receives a cutting completion signal sent by the fire cutting machine, the inverter module is enabled and disconnected, thereby disconnecting the target contactor and causing the target roller conveyor to rise.

[0054] In one embodiment of this application, the target roller conveyor is determined to have risen to the upper limit position by activating the target rising proximity switch, and the upper limit signal of the lifting roller conveyor is generated by the digital input module based on the activation of the target rising proximity switch.

[0055] In one embodiment of this application, after the billet cutting operation is completed, the next process can be carried out, that is, the billet is transported to the next process by controlling the simultaneous rotation of a set of initial lifting rollers.
