[0034] According to the embodiments of the present application, a control method of a roll-over machine is provided.

[0035] Figure 1 is a flowchart of a control method of a roll-over machine according to an embodiment of the present application. As shown in the figure, the method comprises the following steps: Figure 1

[0036] ​Step S102, detecting whether the control unit receives the start signal, and in the case of receiving the start signal, controlling the motor to start, wherein the motor provides power for the turnover of the cage of the dumper.

[0037] Specifically, the control unit is a unit for controlling the operation of the dumper in the control system of the dumper, the start signal is a signal generated by the two-dimensional code image scanning and recognition intelligent module scanning the two-dimensional code mark installed on the car, the two-dimensional code image scanning and recognition intelligent module is connected with the control unit, the cage is a part of the dumper, used for turning over the car loaded with bulk materials, after receiving the start signal, the control unit controls the motor to start working to start the dumper.

[0038] Step S104, judging whether the cage is turned to the first position, and in the case of the cage being turned to the first position, controlling the motor to be closed, wherein the first position is the position of the cage when it is turned around the rotation axis by a first preset angle.

[0039] Specifically, the first position is the position selected after the turnover of the cage to unload the bulk materials in the car, for example, the first preset angle is 216 degrees, the cage triggers a stop signal after being turned by 216 degrees, and the control unit receives the stop signal to control the motor to be closed.

[0040] Step S106, after controlling the motor to be closed, controlling the cage to stop turning when it is turned to the second position, wherein the second position is the position of the cage when it is turned around the rotation axis by a second preset angle, and the second preset angle is greater than the first preset angle.

[0041] Specifically, the second position is the last position reached after the cage stops turning, for example, the second preset angle is 360 degrees, that is, the cage rotates a circle and returns to the initial position before starting to rotate, which ensures that the cage returns to the initial position after turning to avoid manual adjustment of the cage after the cage is misaligned, so that the turning of the cage can be fully automated.

[0042] The control method of the turnover machine provided in the embodiments of the present application comprises the following steps: detecting whether a starting signal is received by a control unit, and controlling a motor to start in the case where the starting signal is received, wherein the motor provides power for the turnover of a turnover cage of the turnover machine; determining whether the turnover cage is turned to a first position, and controlling the motor to stop in the case where the turnover cage is turned to the first position, wherein the first position is the position of the turnover cage when the turnover cage is turned by a first preset angle around a rotation axis; and controlling the turnover cage to stop turning when the turnover cage is turned to a second position after the motor is controlled to stop, wherein the second position is the position of the turnover cage when the turnover cage is turned by a second preset angle around the rotation axis, and the second preset angle is greater than the first preset angle, thereby solving the problem that the turnover cage cannot be accurately returned to the initial position before turning in the related art. The control unit controls the turnover cage to stop turning when the turnover cage is turned to the second position after the motor is controlled to stop, thereby accurately returning the turnover cage to the initial position before turning, and the effect of efficiently loading and unloading bulk materials in the carriage is achieved.

[0043] The turnover cage needs to be accurately positioned to the initial position after the turnover cage is turned over. Optionally, in the control method of the turnover machine provided in the embodiments of the present application, the second preset angle is a multiple of 360°.

[0044] For example, the second preset angle is 360°, and the turnover cage can unload all the bulk materials from the carriage after being turned around the rotation axis for one circle, and does not need to be turned for a second circle. The second position is set to position the stopping position of the turnover cage after turning, thereby facilitating the automatic operation of the turnover machine, reducing the labor cost, and improving the efficiency of the turnover machine.

[0045] After the turnover machine starts to work, the position of the turnover cage of the turnover machine at which the bulk materials are unloaded needs to be determined. Optionally, in the control method of the turnover machine provided in the embodiments of the present application, an inductive switch is arranged on a fixed support of the turnover machine, and the determination of whether the turnover cage is turned to the first position comprises the following steps: detecting whether an induction signal is received by the inductive switch, wherein the induction signal is generated in the case where a first preset mark on the surface of the turnover cage is turned to the induction range of the inductive switch; and determining that the turnover cage is turned to the first position in the case where the induction signal is received by the inductive switch.

[0046] Specifically, the inductive switch is an inductive proximity switch, the first preset mark is an inductive plate corresponding to the inductive proximity switch, the inductive plate is attached to the turnover cage, the inductive plate reaches the induction range of the inductive proximity switch to trigger a stop signal, the control unit controls the motor to stop working, the motor loses power, and the inductive proximity switch is arranged at the position corresponding to 216 degrees of rotation of the turnover cage, i.e., the first position.

[0047] For example, the inductive proximity switch is a three-wire NPN normally open direct current 24v cylindrical inductive proximity switch, also known as a non-contact proximity switch, which is an ideal electronic switch quantity sensor. The inductive proximity switch is used for general travel control, and its positioning accuracy, operation frequency, service life, convenience of installation and adjustment, and adaptability to harsh environments are incomparable to general mechanical travel switches, and is widely used in machine tool, metallurgy, chemical industry, light industry and printing industries, and can be used for limiting, counting, positioning control and automatic protection, etc. In the positioning control link, the inductive proximity switch is used.

[0048] Figure 2 The circuit principle schematic diagram of the inductive proximity switch provided by the embodiment of the present application is shown in Figure 2 The brown line is connected to the positive pole of the power supply, the black line and the blue line are connected to the negative pole of the power supply and the negative pole of the signal, when the metal detection body approaches the sensing area of the switch, the black line and the blue line are in the disconnected state, the control motor is turned off, when the metal detection body is far away from the sensing area of the switch, the black line and the blue line are in the connected state, and the motor works normally. The inductive proximity switch can quickly issue an electrical command without contact, pressure or spark, and accurately reflects the position and travel of the moving mechanism.

[0049] In order to accurately position the turnover cage at the initial position, optionally, in the control method of the dumper provided by the embodiment of the present application, the outer wall of the first hub or the outer wall of the second hub of the dumper is provided with a positioning block, and the inner wall of the fixed support of the dumper is provided with a positioning pin opposite the hub where the positioning block is located. After the control motor is turned off, the control of the dumper is stopped when it is turned over to the second position, comprising: controlling the electromagnetic valve of the positioning pin to be de-energized under the condition that the control motor is turned off, wherein the electromagnetic valve is used to control the positioning pin to be fixed at a preset position under the condition of being energized; under the condition that the electromagnetic valve is de-energized, the positioning pin is controlled to pop out from the preset position by exhausting the control cylinder, so as to control the dumper to stop turning over by the cooperation of the positioning pin and the positioning block when the dumper is turned over to the second position.

[0050] Specifically, the energization and de-energization of the electromagnetic valve controls the retraction and ejection of the positioning pin of the single-acting cylinder. The positioning pin is extended, and the purpose is to prevent the turnover cage of the rotary drum dumper from continuing to turn over under the condition of inertia after the motor is turned off, so as to ensure the balance of the track. The preset position is the position of the positioning pin in the single-acting cylinder when the positioning pin is not ejected. For example, the positioning block is made of a steel plate with a thickness of 100mm, a height of 200mm and a length of 500mm, a square slot of 100*100mm is opened at the top center position of the positioning block, and a hole is opened at the edge side of the positioning block. An M18*150mm bolt with a strength of 8.8 is used for fixation. The positioning pin is controlled to pop out to the preset position to achieve accurate positioning of the dumper.

[0051] The car needs to record the car data when loading and unloading bulk materials. Optionally, in the control method of the dumper provided in the embodiments of the present application, before detecting whether the start signal is received, the method further comprises: scanning the car passing through the dumper by the image recognition device, and triggering the start signal in the case that the second preset mark on the car is scanned.

[0052] For example, the second preset mark is a two-dimensional code nameplate, and the image recognition device can be a two-dimensional code image scanning and recognition intelligent device GX-60. The image recognition device is installed on the front side of the rotary drum dumper, which is used to scan the car data entering the dumper and trigger the start signal at the same time. GX-60 has an IP65 industrial level, and it can maintain good working condition for a long time in the presence of humid or dusty working environment. GX-60 adopts a high-strength ABS shell design, and the internal components are designed to withstand harsh industrial use environments. Even if accidental collision occurs, it will not cause damage to the product. The main parameters include: the scanning mode is inductive scanning; the minimum resolution is 0.127mm; the LED indication is blue+red; the communication interface is RS232; the size is 49.5*40*23.5; the input voltage is 5VDC±10%; the working current is 300mA; the working temperature is 0-50 degrees; the working humidity is 5%-95% without condensation; the environmental brightness is 0-50600lux fluorescent 0-1000lux sunlight; the industrial level is IP65. By scanning the car entering the dumper through the two-dimensional code image scanning and recognition intelligent device GX-60, the number of times the train needs to enter the dumper when loading and unloading bulk materials can be known through the scanning of the two-dimensional code nameplate.

[0053] The electric motor cannot directly drive the dumper cage to overturn. Optionally, in the control method of the dumper provided in the embodiments of the present application, before detecting whether the start signal is received and in the case that the start signal is received, the method further comprises: determining a preset speed reduction ratio of the speed reducer, wherein the electric motor controls the rotation of the speed reducer to control the dumper overturning; after detecting whether the start signal is received and in the case that the start signal is received, the method further comprises: controlling the speed reducer to rotate according to the preset speed reduction ratio to control the overturning of the cage.

[0054] Specifically, the electric motor is a three-phase asynchronous motor, model AC380V, 30KW four-stage motor. The speed reducer is a device used between the electric motor and the dumper to match the speed, which increases the torque by reducing the speed of the electric motor, so that the speed reducer can drive the dumper to overturn. The preset speed ratio is determined by the torque required to drive the dumper to overturn. The three-phase asynchronous motor drives the rotary drum dumper to start overturning through the speed reducer with a fixed speed reduction ratio.
