The control module 100 may be used to control the conveying module 300 to convey the rectangular tubes along the preset conveying direction based on the real-time position and real-time flipping state. The control module 100 may also be used to: when the real-time position of the rectangular tubes is the first position indicating that the rectangular tubes need to be conveyed, control the code scanning and recognition module 400 to scan the product code on the rectangular tubes, so as to identify the target product information of the rectangular tubes through the code scanning and recognition module 400, and control the flipping module 500 to flip the rectangular tubes based on the target product information, preset information, real-time position, and real-time flipping state. The control module 100 may also be used to: when the real-time position of the rectangular tubes is the second position indicating that the flipping of the rectangular tubes is completed, control the conveying module 300 to convey the rectangular tubes from the second position to the blanking area.

[0013] A flipping and conveying control system for rectangular tubes provided by an embodiment of the present invention can realize the automatic control of the transportation and flipping of rectangular tubes by using the flipping and conveying control system, save labor costs, reduce the error rate, and can adapt to different specifications of products. The production line transformation cost is relatively low, it is easy to implement, and it can alleviate problems such as low offline efficiency of rectangular tubes and insufficient adaptability to different specifications of products existing in the existing rectangular tube stacking technology.

[0014] As a possible implementation manner, the preset information may include the correspondence between product information and flipping modes; based on this, referring to Figure 1 As shown, the control module 100 may also be used to: determine the target flipping mode corresponding to the target product information based on the correspondence, and control the flipping module to flip the rectangular tubes according to the target flipping mode based on the real-time position and real-time flipping state.

[0015] Among them, the target flipping mode can be: the first flipping mode indicating that it is necessary to control the first flipping mechanism 501 to flip the rectangular pipe and there is no need to control the second flipping mechanism 502 to flip the rectangular pipe, or the second flipping mode indicating that it is necessary to first control the first flipping mechanism 501 to flip the rectangular pipe and then control the second flipping mechanism 502 to flip the rectangular pipe.

[0016] As a possible implementation manner, refer to Figures 1 to 7 As shown, the first flipping mechanism 501 and the second flipping mechanism 502 can each be provided with a corresponding plurality of flipping frame groups. Each flipping frame group can include a first flipping frame 29 and a second flipping frame 28 arranged in sequence along the preset conveying direction. Electromagnets 21 can be installed on the plurality of second flipping frames 28 of the first flipping mechanism 501 and the second flipping mechanism 502 respectively. Each electromagnet 21 can be connected to the control module 100. Based on this, the control module 100 can also be used to execute one of the following two operation modes: Operation mode 1: If the target flipping mode is the first flipping mode, control the second flipping frame 28 of the first flipping mechanism 501 to rise. When the real-time flipping state is the first flipping state indicating that it is necessary to flip the rectangular pipe once and the real-time position changes from the first position to the first target position on the first flipping frame 29 of the first flipping mechanism 501, control the electromagnet 21 on the first flipping frame 29 of the first flipping mechanism 501 to be magnetized. Control the second flipping frame 28 of the first flipping mechanism 501 to descend and control the first flipping frame 29 of the first flipping mechanism 501 to rise respectively until the real-time flipping state is the second flipping state indicating that the rectangular pipe has been flipped once at the first target position. After the rectangular pipe flipping is completed, control the electromagnet 21 on the first flipping frame 29 of the first flipping mechanism 501 to be demagnetized.

[0017] For the case where the target flipping mode is the first flipping mode, the control module 100 can also control the conveying module 300 to convey the rectangular pipe from the first position along the preset conveying direction to the first target position, and control the conveying module 300 to convey the rectangular pipe from the first target position along the preset conveying direction to the second position.

[0018] Operation mode 2: If the target flipping mode is the second flipping mode, control the second flipping frame 28 of the primary flipping mechanism 501 to rise. When the real-time flipping state is the third flipping state indicating that the rectangular pipe needs to be flipped for the first time and the real-time position changes from the first position to the first target position on the first flipping frame 29 of the primary flipping mechanism 501, control the electromagnet 21 on the first flipping frame 29 of the primary flipping mechanism 501 to magnetize. Then, respectively control the second flipping frame 28 of the primary flipping mechanism 501 to descend and control the first flipping frame 29 of the primary flipping mechanism 501 to rise. Until the real-time flipping state is the fourth flipping state indicating that the rectangular pipe is flipped for the first time at the first target position, control the electromagnet 21 on the first flipping frame 29 of the primary flipping mechanism 501 to demagnetize. Control the second flipping frame 28 of the secondary flipping mechanism 502 to rise. When the real-time flipping state is the fifth flipping state indicating that the rectangular pipe needs to be flipped for the second time and the real-time position changes from the first target position to the second target position on the first flipping frame 29 of the secondary flipping mechanism 502, control the electromagnet 21 on the first flipping frame 29 of the secondary flipping mechanism 502 to magnetize. Then, respectively control the second flipping frame 28 of the secondary flipping mechanism 502 to descend and control the first flipping frame 29 of the secondary flipping mechanism 502 to rise. Until the real-time flipping state is the sixth flipping state indicating that the rectangular pipe is flipped for the second time at the second target position, the flipping of the rectangular pipe is completed, and control the electromagnet 21 on the first flipping frame 29 of the secondary flipping mechanism 502 to demagnetize.

[0019] For the case where the target flipping mode is the second flipping mode, the control module 100 can also control the conveying module 300 to convey the rectangular pipe from the first position to the first target position along the preset conveying direction, and control the conveying module 300 to convey the rectangular pipe from the first target position to the second target position along the preset conveying direction. Then, control the conveying module 300 to convey the rectangular pipe from the second target position to the second position along the preset conveying direction.

[0020] As a possible implementation, refer to Figures 1 to 7 As shown, the flipping module 500 can also include a flipping drive mechanism, which is connected to the control module 100 and is used to drive the primary flipping mechanism 501 to flip the rectangular pipe according to the first flipping mode or drive the primary flipping mechanism 501 and the secondary flipping mechanism 502 to flip the rectangular pipe according to the second flipping mode under the control of the control module 100. Based on this, the control module 100 can also be used to: during the process of the primary flipping mechanism 501 flipping the rectangular pipe according to the first flipping mode, control the magnetization and demagnetization of the electromagnet 21 of the primary flipping mechanism 501; during the process of the primary flipping mechanism 501 and the secondary flipping mechanism 502 flipping the rectangular pipe according to the second flipping mode, control the magnetization and demagnetization of the electromagnets 21 of the primary flipping mechanism 501 and the secondary flipping mechanism 502 respectively.

[0021] Exemplarily, taking Figures 1 to 7 as an example, the flipping drive mechanism may include a solenoid valve group 22, first cylinders corresponding to each first flipping frame 29 (including a first flipping cylinder 23 corresponding to the primary flipping mechanism 501 and a third flipping cylinder 25 corresponding to the secondary flipping mechanism 502), and second cylinders corresponding to each second flipping frame 28 (including a second flipping cylinder 24 corresponding to the primary flipping mechanism 501 and a fourth flipping cylinder 26 corresponding to the secondary flipping mechanism 502); the solenoid valve group 22 is connected to the control module 100 and is used to drive the corresponding first cylinder to drive the first flipping frame 29 corresponding thereto to lift and drive the corresponding second cylinder to drive the second flipping frame 28 corresponding thereto to lift under the control of the control module 100.

[0023] In the actual application process, the conveying mechanism may adopt a plate chain conveyor line, then the driving unit may adopt a frequency converter, and the conveying motor may adopt a plate chain driving motor 12 (as shown in Figure 2 and Figure 3 ); the conveying mechanism may also adopt other conveying devices other than the plate chain conveyor line, then the driving unit and the conveying motor may be adjusted accordingly according to the conveying mechanism, and the devices adopted by the conveying mechanism, the driving unit and the conveying motor respectively are not limited herein.

[0024] As a possible implementation manner, referring to Figures 1 to 7 shown, the detection module 200 may include a plurality of proximity switches connected to the control module 100; the plurality of proximity switches may include an entering proximity switch 1, a first deceleration proximity switch 2, a first in-place proximity switch 3, a second deceleration proximity switch 9, a second in-place proximity switch 20, and a leaving proximity switch 10.

[0025] Exemplarily, referring to Figure 2As shown in the figure, the incoming proximity switch 1 can be installed at the first installation position corresponding to the first position on the conveying mechanism (such as a plate chain conveyor line) to detect the incoming signal indicating that the square and rectangular pipe is at the first position; the first in-place proximity switch 3 can be installed at the second installation position corresponding to the first target position to detect the first in-place signal indicating that the square and rectangular pipe is at the first target position; the second in-place proximity switch 20 can be installed at the third installation position corresponding to the second target position to detect the second in-place signal indicating that the square and rectangular pipe is at the second target position; the leaving proximity switch 10 can be installed at the fourth installation position corresponding to the second position on the conveying mechanism to detect the leaving signal indicating that the square and rectangular pipe is at the second position; the first deceleration proximity switch 2 can be installed at the fifth installation position on the conveying mechanism between the first position and the first target position to detect the first deceleration signal indicating that the square and rectangular pipe needs to decelerate from the current position; the second deceleration proximity switch 9 can be installed at the sixth installation position on the conveying mechanism between the first target position and the second target position to detect the second deceleration signal indicating that the square and rectangular pipe needs to decelerate from the current position. Based on this, the detection module 200 can also be used to determine the real-time position based on the target signals detected by multiple proximity switches.

[0026] As a possible implementation manner, refer to Figures 1 to 7 As shown in the figure, the detection module 200 may further include a plurality of magnetic switches connected to the control module 100. Each first cylinder and each second cylinder are respectively installed with a corresponding magnetic switch, and each magnetic switch is used to detect the telescopic state of the first cylinder or the second cylinder corresponding thereto. Based on this, the detection module 200 can also be used to: determine the real-time flipping state based on the telescopic states detected by the plurality of magnetic switches.

[0027] As a possible implementation manner, refer to Figures 1 to 7 As shown in the figure, the flipping and conveying control system may further include an electrical control cabinet 6; the control module 100 (including a logic control unit and a signal control unit) and the driving unit (such as an inverter) can be installed inside the electrical control cabinet 6.

[0028] As a possible implementation manner, refer to Figures 1 to 7 As shown in the figure, the control module 100 may include a logic control unit and a signal control unit; based on this, the signal control unit can be used to: send the real-time position and / or the real-time flipping state detected by the detection module 200 to the logic control unit, and send the control instruction generated by the logic control unit based on the real-time position and / or the real-time flipping state to at least one of the conveying module 300, the code scanning and recognition module 400, and the flipping module 500; send the target product information recognized by the code scanning and recognition module 400 to the logic control unit, and send the target flipping mode determined by the logic control unit based on the corresponding relationship to the conveying module 300 and the flipping module 500.

[0029] Exemplarily, for example Figures 1 to 7 As shown, the detection module 200 sends the detected real-time position and real-time flipping state of the square and rectangular pipe to the signal control unit. The signal control unit sends the received real-time position and real-time flipping state to the logic control unit. The logic control unit generates corresponding control instructions for controlling the target modules (such as the conveying module 300, the code scanning and recognition module 400, the flipping module 500) by using the received real-time position and real-time flipping state and sends them to the signal control unit. The signal control unit sends this control instruction to the target module to control the working state of the target module through this control instruction; when the square and rectangular pipe is at the first position, the incoming proximity switch 1 sends the detected incoming signal to the signal control unit. The signal control unit sends the received incoming signal to the logic control unit. After receiving the incoming signal, the logic control unit determines the target flipping mode corresponding to the target product information by using the correspondence between the product information and the flipping mode and sends it to the signal control unit. The signal control unit sends this target flipping mode to the conveying module 300 and the flipping module 500 so that the subsequent conveying module 300 and the flipping module 500 convey and flip the square and rectangular pipe according to this target flipping mode.

The solenoid valve group 22 of the flipping module 500 is used to control the working states of the first flipping cylinder 23 and the second flipping cylinder 24 respectively; The product code scanning and recognition module 400 is docked with the signal control unit in an RJ45 manner, scans and recognizes the code assigned to the incoming product (i.e., the square and rectangular pipe at the first position), and sends the recognized product information to the signal control unit, so that the signal control unit can send the product information to the logic control unit to determine the flipping method (i.e., flipping 90 degrees or flipping 180 degrees) and the blanking method of the pipe product; During the working process of the flipping and conveying control system, the proximity switches used to achieve a 180-degree flip of the square and rectangular pipe (i.e., two 90-degree flips) mainly include the entry proximity switch 1, the first deceleration proximity switch 2, the first in-place proximity switch 3, the second deceleration proximity switch 9, the second in-place proximity switch 20, and the departure proximity switch 10. The proximity switch 1, the first deceleration proximity switch 2, and the first in-place proximity switch 3 are respectively used to detect the entry position (corresponding to the first position), the deceleration position (corresponding to the position where the square and rectangular pipe needs to decelerate), the stop position (corresponding to the first target position and the second target position), and the departure position (corresponding to the second position) during the 180-degree process of the flipped square and rectangular pipe; The third 90-degree flipping mechanism 7, the fourth 90-degree flipping mechanism 8, the fifth 90-degree flipping mechanism 11, and the sixth 90-degree flipping mechanism 14 belong to the secondary flipping mechanisms; the solenoid valve group 22 of the flipping module 500 is used to control the working states of the third flipping cylinder 25 and the fourth flipping cylinder 26 respectively; Due to the installation of a deceleration proximity switch and a positioning proximity switch, the logic control unit can generate corresponding deceleration frequencies and stop frequencies respectively when the pipe product triggers the deceleration proximity switch and the positioning proximity switch, and send them to the signal control unit, so that the signal control unit can send the deceleration frequency and the stop frequency to the frequency converter, and adjust the working state of the plate chain drive motor 12 through the frequency converter, and then control the conveyor line through the plate chain drive motor 12 to make the pipe product stop steadily at the corresponding target position; In order to detect whether the flipping is in place, magnetic switches are set on the corresponding cylinders to detect the flipping state in real time.

[0037] See Figure 8 As shown, the working process of the flipping conveyor control system mainly includes the following steps: First step, the pipe product enters from the incoming material end, and the incoming proximity switch 1 is triggered (at this time, the pipe product is at the first position).

[0038] The incoming proximity switch 1 is connected to the signal control unit. After the incoming proximity switch 1 is triggered, it will send the detected incoming signal to the signal control unit. The signal control unit receives the position detection signal (i.e., the incoming signal) and feeds it back to the logic controller (i.e., the logic control unit at this time).

[0039] Second step, control the power transmission device to start the drive motor (i.e., the plate chain drive motor 12) through the frequency converter.

[0040] The frequency converter is connected to the signal control unit in the way of profinet communication. The logic controller sends a transmission command to the frequency converter through the signal control unit to set the frequency of the frequency converter and give a start command through the transmission command, and the frequency converter starts the drive motor.

[0041] Third step, control the second flipping frame 28 of the first flipping mechanism 501 to rise.

[0042] The logic controller sends a flipping cylinder extension command to the solenoid valve group 22 through the signal control unit to control the solenoid valve group 22 to drive the second flipping cylinder 24 corresponding to the first flipping mechanism 501 to extend, and then drive the second flipping frame 28 of the first flipping mechanism 501 to rise. The magnetic switch (i.e., the magnetic switch) connected to the signal control unit in the way of IO signal interaction on the second flipping cylinder 24 feeds the extension in-place signal back to the signal control unit.

[0043] Fourth step, the first deceleration proximity switch 2 is triggered.

[0044] When the pipe product triggers the first deceleration proximity switch 2, the detected deceleration signal is fed back to the signal control unit. The logic controller connected to the signal control unit uses the deceleration signal to generate a deceleration command and sends it to the frequency converter through the signal control unit, so as to give the deceleration frequency and the deceleration instruction to the frequency converter through the deceleration command, and the frequency converter decelerates the drive motor.

[0045] Step 5, the first in-place proximity switch 3 is triggered.

[0046] When the pipe product triggers the first in-place proximity switch 3, the detected in-place signal is fed back to the signal control unit. The logic controller connected to the signal control unit uses the in-place signal to generate a stop command and sends it to the frequency converter through the signal control unit, so as to give the stop instruction to the frequency converter through the stop command, and the frequency converter stops the drive motor.

[0047] Step 6, the code scanning mechanism 5 (i.e., the code scanning and recognition module 400) scans the code.

[0048] The code scanning mechanism 5 is connected to the signal control unit in the way of profinet communication. The logic controller generates a code scanning control instruction and sends it to the code scanning mechanism 5 through the signal control unit to control the code scanning mechanism 5 to scan and recognize the product information of the pipe product. The code scanning mechanism 5 feeds back the code scanning completion signal and the product information to the signal control unit. After receiving the code scanning completion signal and obtaining the product information, the logic controller connected to the signal control unit determines whether the pipe product needs to be flipped by 90 degrees or 180 degrees by using the product information.

[0049] If the logic controller determines that the pipe product needs to be flipped by 90 degrees, the following steps 7 to 9 are executed. After step 9 is completed, the departure proximity switch 10 is triggered and the pipe product goes offline. If the logic controller determines that the pipe product needs to be flipped by 180 degrees, the following steps 7 to 15 are executed. After step 15 is completed, the departure proximity switch 10 is triggered and the pipe product goes offline.

[0050] Step 7, the electromagnet 21 corresponding to the first flipping mechanism 501 is magnetized.

[0051] The controller of the electromagnet is connected to the signal control unit in the way of IO signal interaction. The logic controller generates a magnetization command and sends it to the controller of the electromagnet 21 corresponding to the first flipping mechanism 501 through the signal control unit to control the magnetization of the electromagnet 21. After the electromagnet 21 is magnetized, the electromagnet 21 feeds back the magnetization completion signal to the signal control unit.

[0052] Step 8, the pipe product is flipped by 90°.

[0053] The logic controller generates a single flip command (for controlling the second flip frame 28 of the single flip mechanism 501 to fall back and controlling the first flip frame 29 of the single flip mechanism 501 to rise), and sends it to the solenoid valve group 22 through the signal control unit. The solenoid valve group 22 drives the corresponding first flip cylinder 23 of the single flip mechanism 501 to extend and drives the corresponding second flip cylinder 24 of the single flip mechanism 501 to retract. The single flip mechanism 501 undergoes the second flip frame 28 falling back and the first flip frame 29 rising. The magnetic open feedback retraction in-place signal and the extension in-place signal, which are respectively connected to the signal control unit in an IO signal interaction manner on the second flip frame 28 and the first flip frame 29, are sent back to the signal control unit.

[0054] In the ninth step, the 90° flipping of the pipe product is completed, and the electromagnet 21 corresponding to the single flip mechanism 501 is demagnetized. The control power transmission device starts the drive motor through the frequency converter.

[0055] The logic controller generates a demagnetization command and sends it to the electromagnet 21 corresponding to the single flip mechanism 501 through the signal control unit to control the demagnetization of the electromagnet 21. After the demagnetization of the electromagnet 21 is completed, the electromagnet 21 feeds back a demagnetization completion signal to the signal control unit. The logic controller sends a transmission command to the frequency converter connected to the signal control unit in a profinet communication manner through the signal control unit, so as to set the frequency of the frequency converter and give a start instruction through the transmission command, and the frequency converter starts the drive motor.

[0056] For the situation where the logic controller determines that the pipe product needs to be flipped by 90 degrees, after the ninth step, the departure proximity switch 10 is triggered, and the pipe product exits the line. Specifically, the departure proximity switch 10 connected to the signal control unit is triggered, and the signal control unit feeds back the departure signal detected by the departure proximity switch 10 to the logic controller, and the pipe product exits the line, completing the flipping and conveying of the square and rectangular pipes.

[0057] In the tenth step, control the second flip frame 28 of the double flip mechanism 502 to rise.

[0058] The logic controller sends a flip cylinder extension command to the solenoid valve group 22 through the signal control unit to control the solenoid valve group 22 to drive the corresponding fourth flip cylinder 26 of the double flip mechanism 502 to extend, thereby driving the second flip frame 28 of the double flip mechanism 502 to rise. The magnetic open feedback extension in-place signal on the fourth flip cylinder 26, which is connected to the signal control unit in an IO signal interaction manner, is sent to the signal control unit.

[0059] In the eleventh step, the second deceleration proximity switch 9 is triggered.

[0060] When the pipe product triggers the second deceleration proximity switch 9, the detected deceleration signal is fed back to the logic controller through the signal control unit. The logic controller generates a deceleration command using the deceleration signal and sends it to the frequency converter through the signal control unit, so as to set the deceleration frequency and the deceleration instruction for the frequency converter through the deceleration command, and the frequency converter decelerates the drive motor.

[0061] Step 12, the second in-place proximity switch 20 is triggered.

[0062] When the pipe product triggers the second in-place proximity switch 20, the detected in-place signal is fed back to the logic controller through the signal control unit. The logic controller unit generates a stop command using the in-place signal and sends it to the frequency converter through the signal control unit, so as to set the stop instruction for the frequency converter through the stop command, and the frequency converter stops the drive motor.

[0063] Step 13, the electromagnet 21 corresponding to the secondary flipping mechanism 502 is magnetized.

[0064] The logic controller generates a magnetization command and sends it to the controller of the electromagnet 21 corresponding to the secondary flipping mechanism 502 through the signal control unit to control the magnetization of the electromagnet 21. After the magnetization of the electromagnet 21 is completed, the electromagnet 21 feeds back a magnetization completion signal to the signal control unit.

[0065] Step 14, the pipe product is flipped 180°.

[0066] The logic controller generates a secondary flipping command (for controlling the lowering of the second flipping frame 28 of the secondary flipping mechanism 502 and the raising of the first flipping frame 29 of the secondary flipping mechanism 502) and sends it to the solenoid valve group 22 through the signal control unit. The solenoid valve group 22 drives the extension of the third flipping cylinder 25 corresponding to the secondary flipping mechanism 502 and the retraction of the fourth flipping cylinder 26 corresponding to the secondary flipping mechanism 502. The secondary flipping mechanism 502 undergoes the lowering of the second flipping frame 28 and the raising of the first flipping frame 29. The magnetic switches on the second flipping frame 28 and the first flipping frame 29 that are connected to the signal control unit in an IO signal interaction manner respectively feedback the retraction in-place signal and the extension in-place signal to the signal control unit.

[0067] Step 15, the 180° flipping of the pipe product is completed, the electromagnet 21 corresponding to the secondary flipping mechanism 502 is demagnetized, and the control power transmission device starts the drive motor through the frequency converter.

[0068] The logic controller generates a demagnetization command and sends it to the electromagnet 21 corresponding to the secondary flipping mechanism 502 through the signal control unit to control the demagnetization of the electromagnet 21. After the demagnetization of the electromagnet 21 is completed, the electromagnet 21 feeds back a demagnetization completion signal to the signal control unit. The logic controller sends a transmission command to the frequency converter through the signal control unit to set the frequency and the start instruction for the frequency converter through the transmission command, and the frequency converter starts the drive motor.

[0069] In the case where the logic controller determines that the pipe product needs to be flipped by 180 degrees, after the fifteenth step, the departure proximity switch 10 is triggered, and the pipe product exits the line, completing the flipping and conveying of the square and rectangular pipes.
