Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a control system for a tire changer according to an embodiment of the present invention.
An embodiment of the utility model provides a control system 100 for tire dismouting machine, include: the leakage protector 110 is connected to the alternating current power supply 101 and used for cutting off the alternating current power supply when the leakage current is larger than a preset threshold value; an ac contactor 120, a primary side of which is connected in series to the leakage protector, for controlling on/off of an ac power supply; a rectifying module 130 connected to the ac contactor, for converting ac power into dc power; a motor 140 connected to the ac contactor through a forward/reverse rotation control switch; the controller 150 is connected with the double-head electromagnetic valve group 170 and is used for controlling the on-off of a power supply of the double-head electromagnetic valve group; the double-end solenoid valve group includes: the N double-end electromagnetic valves are used for controlling the on-off of air flow, wherein N is a positive integer; and the human-computer interaction device 160 is connected with the controller and is used for inputting control signals and displaying the current working state.
In the embodiment of the invention, the leakage protector 110 and the alternating current contactor 120 are utilized to enhance the overall electrical safety of the equipment, when the whole equipment leaks electricity, the leakage protector, called a leakage switch for short, also called a leakage breaker, is mainly used for protecting the electric shock of a person with fatal danger when the equipment has leakage faults, has the functions of overload and short circuit protection, can be used for protecting the overload and short circuit of a line or a motor, and can also be used for the infrequent switching and starting of the line under the normal condition. The working principle of the alternating current contactor is that the contact is connected and disconnected by matching electromagnetic force with the elastic force of a spring. The alternating current contactor has two working states, namely a power-off state (release state) and a power-on state (action state). When the attraction coil is electrified, the static iron core generates electromagnetic attraction force, the armature is attracted, and the connecting rod connected with the armature drives the contact to act, so that the normally closed contact breaking contactor is in an electrified state; when the attraction coil is powered off, the electromagnetic attraction force disappears, the armature is reopened, the normally open contact is closed, the normally open contact is released under the action of the position spring, all the contacts reset accordingly, and the contactor is in a power-off state. In this embodiment, double-end solenoid valve adopts well seal type solenoid valve, can be in the cylinder to gas seal under the outage state to guarantee the stability of cylinder, let the cylinder keep at last outage state.
Further, in order to realize on-off control of the whole alternating current power supply, a stop switch and a start switch can be connected to the secondary side of the alternating current contactor; the stop switch is used for controlling the alternating current contactor to cut off the alternating current power supply; the starting switch is used for controlling the alternating current contactor to be connected with the alternating current power supply. Thereby, convenient electrical control can be realized. Furthermore, in order to facilitate the on-off control of the equipment function by the staff, the human-computer interaction device can be a touch display screen; the touch display screen and the controller are integrally arranged. Therefore, the double-head electromagnetic valve group can be conveniently controlled by inputting through the touch display screen, and multiple functions are realized. It is worth to be noted that an ammeter and a voltage transformer can be arranged; the ammeter is used for measuring the current value of the alternating current power supply; and the voltage transformer is used for measuring the voltage value of the alternating current power supply. And the man-machine interaction device is a display which can display the current value and the voltage value.
In addition, for the selection of the Controller, since the actual working environment is flexible and changeable, the Controller can be set as a PLC (Programmable Logic Controller) Controller. Programmable logic controllers, which employ a type of programmable memory for storing programs therein, executing user-oriented instructions such as logic operations, sequence control, timing, counting, and arithmetic operations, and controlling various types of machinery or manufacturing processes via digital or analog input/output. The programmable logic controller is essentially a computer dedicated to industrial control, the hardware structure of which is basically the same as that of a microcomputer, and comprises: the power supply, the power supply for the programmable logic controller, plays an important role in the overall system. The Central Processing Unit (CPU) is the control hub of the programmable logic controller. It receives and stores the user program and data input from the programmer according to the function assigned by the programmable logic controller system program; the states of the power supply, memory, I/O, and watch dog timer are checked, and syntax errors in the user program can be diagnosed. When the programmable logic controller is put into operation, it firstly receives the state and data of each input device in the field in the scanning mode, and stores them in I/O mapping area, then reads user program from user program memory one by one, and after command interpretation, the result of executing logic or arithmetic operation according to the instruction is sent to I/O mapping area or data register. And after all the user programs are executed, finally transmitting each output state of the I/O mapping area or the data in the output register to a corresponding output device, and circularly operating until stopping operation.
In order to further improve the reliability of the programmable logic controller, a redundant system is formed by adopting double CPUs or a voting system of three CPUs is adopted for the large programmable logic controller. Thus, even if a certain CPU fails, the whole system can still operate normally.
Further, a safety device may be provided between the ac contactor and the motor. Therefore, the motor can be stopped in time when the power of the motor is overlarge. And a 3A safety bank correspondingly connected with the N double-head electromagnetic valves in series can be further arranged. Therefore, the current of the double-end electromagnetic valve can be controlled, and the double-end electromagnetic valve is prevented from being burnt out due to overlarge current.
In order to make the wiring of the whole control system more concise, a wiring bar can be used for connecting lines and devices, for example, the wiring bar can be connected to the rectifier module, so that the double-head electromagnetic valve group and the controller can be conveniently connected to supply power to the double-head electromagnetic valve group and the controller.
