Description

Technical Field

[0001] The invention relates to the technical field of waste treatment, and in particular to a waste treatment control system and a control method for a pipe product. Background Art

[0002] In modern industrial production, shot blasting machines, as an important surface treatment equipment, are widely used in processes such as deoxidation, rust removal, strengthening and pretreatment of metal materials. However, shot blasting machines generate a large amount of waste during operation. Although some shot blasting processes have taken waste treatment and collection into consideration during design and implementation, there are still many deficiencies. Especially for tubular materials such as square tubes, after shot blasting, there is often waste residue inside that is difficult to remove.

[0003] Traditional waste treatment methods, such as purging, can remove waste on the surface of the pipe to a certain extent, but are often unable to deal with the waste residue inside the pipe. Since the purging airflow is difficult to penetrate into the interior of the pipe, coupled with the adhesion of the waste residue and the complexity of the internal structure of the pipe, it is difficult for the traditional purging method to achieve the ideal cleaning effect. Therefore, in actual production, manual intervention is required again, which will cause unsafe factors during the operation of the line, and will also cause the subsequent production processes to be affected by the waste, resulting in unqualified products.

[0079] For tubular materials such as square tubes, after shot blasting, there is often waste residue that is difficult to remove inside. Although traditional waste treatment methods, such as purging, can remove waste on the surface of the pipe to a certain extent, they are often unable to deal with the waste residue inside the pipe. Since it is difficult for the purge airflow to penetrate deep into the pipe, coupled with the adhesion of the waste residue and the complexity of the internal structure of the pipe, it is difficult for the traditional purging method to achieve the ideal cleaning effect. Therefore, in actual production, manual intervention is required again, which will produce unsafe factors during the operation of the line, and will also cause the subsequent production processes to be affected by the waste and produce unqualified products. Therefore, the current treatment method has the problem of not being able to completely dispose of the waste of pipe products, resulting in an increase in the unqualified rate of products.

[0080] Example 1

[0081] The embodiment of the present invention provides a waste treatment control system for pipe products, which effectively solves the problem that the current treatment method cannot completely treat the waste of pipe products, resulting in an increase in the unqualified rate of products. In the embodiment of the present invention, the waste treatment control system is used to treat waste of square and rectangular pipes, and is applied to a transmission line for pipes, which includes a first transmission line and a second transmission line, and the second transmission line is arranged at the rear of the first transmission line. Figure 1 is a first schematic diagram of the structure of a waste treatment control system for a pipe product provided by an embodiment of the present invention, Figure 2 2 is a second schematic diagram of the waste treatment control system structure of the pipe product provided by the embodiment of the present invention. Figure 1 and Figure 2 As shown, the waste processing control system includes: a photoelectric detection module 110, a power transmission module 120, a centering clamping module 130, a flipping control module 140, a waste cleaning module 150 and a signal control module 160.

[0082] The photoelectric detection module 110 is used to detect the position signal of the pipe product on the first transmission line and the second transmission line, and send the position signal to the signal control module 160. The photoelectric detection module 110 includes an entry photoelectric detection unit 111, a deceleration photoelectric detection unit 112, a stop photoelectric detection unit 113 and a departure photoelectric detection unit 114, wherein: the entry photoelectric detection unit 111 is arranged on both sides of the first transmission line, and the deceleration photoelectric detection unit 112, the stop photoelectric detection unit 113 and the departure photoelectric detection unit 114 are all arranged on both sides of the second transmission line. Optionally, the entry photoelectric detection unit 111, the deceleration photoelectric detection unit 112, the stop photoelectric detection unit 113 and the departure photoelectric detection unit 114 can all be opposite photoelectrics, and the opposite photoelectric transmitter emits a light signal of a specific wavelength based on the photoelectric effect, and these light signals directly enter the receiver. When the pipe product passes between the transmitter and the receiver and blocks the light, the light intensity received by the receiver will be greatly reduced. Through the signal processing circuit, this position information can be converted into a digital or analog signal and sent to the signal control module 160 for processing, thereby realizing automatic detection and positioning.

[0083] In the embodiment of the present invention, the entry photoelectric detection unit 111 is arranged at the conveying port of the first transmission line, and is used to detect the entry signal of the pipe product and send it to the signal control module 160. The deceleration photoelectric detection unit 112 is used to detect the deceleration signal of the pipe product and send it to the signal control module 160, and the stop photoelectric detection unit 113 is used to detect the stop signal of the pipe product and send it to the signal control module 160. The deceleration photoelectric detection unit 112 and the stop photoelectric detection unit 113 are arranged on both sides of the end of the second transmission line. When the pipe product triggers the deceleration and stop photoelectric detection units 113, the signal control module 160 outputs the corresponding deceleration and stop frequencies, so that the pipe product stops smoothly at the end of the second transmission line. The departure photoelectric detection unit 114 is arranged at the output port of the second transmission line, and is used to detect the departure signal of the pipe product and send it to the signal control module 160. The signal control module 160 is used to send a transmission command to the power transmission module 120 when it is detected that the pipe product enters the transmission line according to the position signal.

[0084] The power transmission module 120 is used to transmit power to the first transmission line and the second transmission line according to the transmission command, so as to drive the pipe product to the target position. The power transmission module 120 includes a first conveying motor 121 and a second conveying motor 122, which are horizontally arranged at the bottom of the transmission line, the first conveying motor 121 is installed at the bottom of the roller of the first transmission line, and the second conveying motor 122 is installed at the bottom of the roller of the second transmission line. The first conveying motor 121 is used to receive the first transmission command of the signal control module 160 to control the rotation of the roller of the first transmission line, and the second conveying motor 122 is used to receive the second transmission command of the signal control module 160 to control the rotation of the roller of the second transmission line. The first conveying motor 121 and the second conveying motor 122 both adopt a variable frequency adjustable control method, so that the pipe product can move smoothly from the conveying port of the transmission line to the target position at the end of the transmission line, and then stop transmitting power to the first transmission line and the second transmission line.

[0085] The signal control module 160 is also used to send a clamping command to the centering clamping module 130, and the centering clamping module 130 is used to clamp and fix the pipe product according to the clamping command. The centering clamping module 130 includes a blocking cylinder 131, three centering cylinders 132, and three first proximity switches 133. The blocking cylinder 131, the three centering cylinders 132, and the three first proximity switches 133 are all arranged on the second transmission line, and the three groups of centering cylinders 132 can adapt to the centering clamping of different products.

[0086] The blocking cylinder 131 is used to receive the blocking command from the signal control module 160 to block the pipe product on the second transmission line. When the pipe product stops at the blocking cylinder 131, the centering cylinder 132 is used to receive the clamping command to center and clamp the pipe product. The first proximity switch 133 is used to detect whether the pipe product is clamped in place. The signal of the first proximity switch 133 is input into the signal control module 160.

[0087] The signal control module 160 is also used to send a flip command to the flip control module 140 when it is detected that the waste collection device 200 reaches the preset position. The flip control module 140 is used to control the second transmission line to flip according to the flip command. The flip control module 140 includes a hydraulic station 141, a hydraulic cylinder 142, a second proximity switch 143 and a detection photoelectric 144. The hydraulic station 141 and the hydraulic cylinder 142 are fixed at the lower part of the second transmission line. The hydraulic cylinder 142 is driven to move by the operation of the hydraulic station 141. The operation of the hydraulic station 141 is controlled by the signal control module 160 to start and stop.

[0088] The hydraulic station 141 is provided with a solenoid valve, which is connected to the signal control module 160, so as to realize the functions of deceleration and stopping, so that it runs smoothly. The signal control module 160 outputs a flipping command to the solenoid valve, and the hydraulic station 141 receives the flipping command and outputs sufficient torque to drive the hydraulic cylinder 142 to lift and flip, thereby flipping the second transmission line. The second proximity switch 143 can detect the flipping angle of the hydraulic cylinder 142 in real time, and stop the hydraulic action when the appropriate angle is reached. The detection photoelectric 144 is used to detect the in-place status of the waste collection device 200 before the second transmission line is flipped. The waste collection device 200 is provided with a photoelectric switch, and the detection photoelectric 144 is interlocked with the signal of the photoelectric switch. The waste collection device 200 will not be flipped when it is not in place.

[0089] The signal control module 160 is also used to send a cleaning command to the waste cleaning module 150 when it is detected that the second transmission line is flipped to a preset angle. The waste cleaning module 150 is used to clean the waste in the pipe product to the waste collection device 200 according to the cleaning command. The waste cleaning module 150 includes a vibrator 151 and a blowing mechanism 152, which are arranged on the upper part of the second transmission line. The vibrator 151 is used to receive the cleaning command to vibrate and clean the pipe product, and the blowing mechanism 152 is used to receive the cleaning command to blow and clean the pipe product. The vibrator 151 is provided with a vibration solenoid valve, and the blowing mechanism 152 is provided with a blowing solenoid valve. The signal control module 160 is connected to the vibration solenoid valve and the blowing solenoid valve respectively, and the first delay time and the second delay time of the vibration solenoid valve and the blowing solenoid valve can be set respectively. The vibrator 151 and the blowing mechanism 152 start working at the same time, which can improve the waste processing capacity, and can be set to stop working after a certain delay.

[0090] The signal control module 160 includes an electrical control cabinet 161, a logic control unit, a hydraulic station contact unit and a motor frequency conversion unit. The logic control unit, the hydraulic station contact unit and the motor frequency conversion unit are arranged inside the electrical control cabinet 161, and the logic control unit is connected to the hydraulic station contact unit and the motor frequency conversion unit respectively.

[0092] The logic control unit is used to receive position signals and send transmission commands, clamping commands, flipping commands and cleaning commands to perform logic control on each module. In the embodiment of the present invention, the logic control unit adopts a programmable logic controller.

Fig.10 As shown, the control method includes the following steps:

[0097] S100, the photoelectric detection module detects the position signal of the pipe product on the first transmission line, and sends the position signal to the signal control module.

[0098] When the entry photoelectric detection unit 111 detects an entry signal of the tubular product, the entry signal is sent to the logic control unit.

[0099] S200: When the signal control module detects that the pipe product enters the first transmission line according to the position signal, the signal control module sends a transmission command to the power transmission module.

[0100] The logic control unit outputs a signal to the motor frequency conversion unit, and the motor frequency conversion unit sends a first transmission command and a second transmission command to the first conveying motor 121 and the second conveying motor 122 respectively.

[0101] S300, the power transmission module transmits power to the first transmission line and the second transmission line according to the transmission command to drive the pipe product to be transmitted to the target position, and stops transmitting power to the first transmission line and the second transmission line.

[0102] The first conveying motor 121 receives the first transmission command to control the roller of the first transmission line to rotate, and the second conveying motor 122 receives the second transmission command to control the roller of the second transmission line to rotate, thereby driving the transmission of the tubular product. At the same time, the logic control unit outputs an extension instruction to the blocking cylinder 131 to control the blocking cylinder 131 to extend into place. When the tubular product reaches the position of the deceleration photoelectric detection unit 112, the deceleration signal of the deceleration photoelectric detection unit 112 is transmitted to the logic control unit, and the logic control unit gives the motor frequency conversion unit a deceleration frequency, thereby controlling the first conveying motor 121 and the second conveying motor 122 to decelerate. When the tubular product reaches the position of the stop photoelectric detection unit 113, the stop signal of the stop photoelectric detection unit 113 is transmitted to the logic control unit, and the logic control unit gives the motor frequency conversion unit a stop instruction, thereby controlling the first conveying motor 121 and the second conveying motor 122 to stop.

[0103] S400: The signal control module sends a clamping command to the centering clamping module.

[0104] In the embodiment of the present invention, the logic control unit outputs a clamping command to the three centering cylinders 132 .

[0105] S500, the centering clamping module clamps and fixes the pipe product according to the clamping command.

[0106] The three centering cylinders 132 clamp and fix the pipe product according to the clamping command, and the first proximity switch 133 detects whether the pipe product is clamped in place and feeds back the switch signal to the logic control unit.

[0107] S600: When the signal control module detects that the waste collection device reaches a preset position, it sends a flip command to the flip control module.

[0108] When the detection photoelectric 144 detects that the waste collection device 200 is in place, the state signal is fed back to the logic control unit, the logic control unit transmits a signal to the hydraulic station contact unit, and the hydraulic station contact unit outputs a flip command.

[0109] S700: The flip control module controls the second transmission line to flip according to the flip command.

[0110] The hydraulic station 141 receives the flipping command and outputs sufficient torque to drive the hydraulic cylinder 142 to lift and flip. By controlling the solenoid valve, the hydraulic cylinder 142 is extended, decelerated, and then stopped, thereby flipping the second transmission line.

[0111] S800: When the signal control module detects that the second transmission line is flipped to a preset angle, a cleaning command is sent to the waste cleaning module.

[0112] The second proximity switch 143 detects the flipping angle of the hydraulic cylinder 142 in real time. When the appropriate angle is reached, the hydraulic action is stopped, the flipping is completed and a high-level signal is fed back to the logic control unit, which sends a cleaning command to the vibrator 151 and the blowing mechanism 152 and sets a delay time.

[0113] S900, the waste cleaning module cleans the waste in the pipe product to the waste collection device according to the cleaning command.

[0117] In the embodiment of the present invention, the logic control unit controls the hydraulic station contact unit to send a fall-back command to the hydraulic station 141 .

[0118] S1100. The flip control module controls the second transmission line to flip and fall back according to the fall back command.

[0119] In the embodiment of the present invention, the solenoid valve of the hydraulic station 141 is controlled to control the hydraulic cylinder 142 to retract, first decelerate and then stop, so that the second transmission line falls back.

[0120] S1200: After the second transmission line is flipped and dropped back, the signal control module sends a release command to the centering clamping module.

[0121] The second proximity switch 143 feeds back a low level signal, and the flipping and falling back is completed, and the logic control unit sends a release command to the first proximity switch 133 .

[0122] S1300, the centering clamping module releases the pipe product according to the release command.

[0123] The first proximity switch 133 receives the release command and controls the centering cylinder 132 to release the tubular product. At the same time, the logic control unit outputs a retraction signal to control the blocking cylinder 131 to descend.

[0124] S1400, the signal control module sends a transmission command to the power transmission module to transmit the pipe product out of the second transmission line.

[0125] The logic control unit gives the motor frequency conversion unit a frequency to start, and the motor frequency conversion unit sends a transmission command to the first conveying motor 121 and the second conveying motor 122, thereby conveying the pipe product to the next station for processing. The logic control unit detects that the photoelectric detection unit 114 changes from a high level state to a low level state. If other photoelectric signals on the transmission line do not detect the pipe product, it means that the waste processing work of the control system is completed.
