Description

Technical Field

[0001] The invention belongs to the field of wire tube production equipment, and in particular relates to a wire tube unwinding control method. Background Art

[0002] The production and transportation of wire pipes are both coiled, that is, the wire pipes are coiled on reels. The reels used for winding the wire pipes have a certain width and diameter. In the production process, in order to prevent adjacent wire pipes from scratching each other when unwinding, a pipe arranger is designed at the outlet of the wire pipe to ensure that the wire pipe and the reel are pulled out basically vertically. Under the action of traction, the wire pipe drives the reel to rotate, and the wire pipe is bound to have a certain angle at the pipe arranger and guide assembly. When the wire pipe is continuously pulled out, not only stress will be generated inside the wire pipe, but also the outer surface of the wire pipe will be scratched. The larger the angle, the greater the stress and the more severe the scratch, while the smaller the angle, the larger the area occupied by the production line. In addition, in order to ensure that the wire pipe is pulled out of the reel vertically, it is necessary to manually adjust and control the movement of the pipe arranger, which increases the labor intensity of the workers. Summary of the invention

[0003] The object of the present invention is to provide a wire tube unwinding control method to overcome the above technical defects.

[0004] In order to solve the above technical problems, the present invention provides a wire tube unwinding control method suitable for unwinding the wire tube, comprising: Step 100, arranging a reel, a pipe arranger, and a guide assembly in sequence along the pulling direction of the wire pipe, wherein the wire pipe is wound around the reel row by row; Step 200, pulling the wire tube, and the wire tube drives the reel to rotate; In step 300, the wire tube passes through the tube rack. If the wire tube deviates, the tube rack is triggered to generate a pulse signal. The PLC receives the pulse signal and controls the reel to move horizontally along the axis of the reel until the deviation of the wire tube is corrected, ensuring that the wire tube is pulled out vertically from the reel.

[0005] According to a wire tube unwinding control method, the tube arranging device comprises: A base plate is slidably mounted on the base, and a sliding direction is parallel to the axial center line of the reel; A steering wheel assembly, wherein the steering wheel assembly is composed of two steering wheels mounted on the base plate, wherein the two steering wheels are a first steering wheel and a second steering wheel, and the wire tube passes between the two steering wheels and drives the steering wheels to rotate; A signaling block, wherein a first signaling block is fixed on the first steering wheel, and a second signaling block is fixed on the second steering wheel; A signal transmitting switch is provided on the substrate to sense the first signal transmitting block, and a second signal transmitting switch is provided on the substrate to sense the second signal transmitting block.

[0006] According to a wire tube unwinding control method, the guide assembly is composed of two guide wheels, the wire tube passes between the two guide wheels, and the gap between the two guide wheels is adjustable.

[0007] According to a wire tube unwinding control method, the method further includes: A reel trolley, in which the reel is installed; PLC, the PLC is connected to the signal-transmitting switch and the reel trolley through signals.

[0008] According to a wire tube unwinding control method, in step 300, the wire tube passes through the tube arranging device. If the wire tube deviates, the tube arranging device is triggered to generate a pulse signal, and the PLC receives the pulse signal. The PLC controls the reel to move laterally along the reel axis until the deviating of the wire tube is corrected to ensure that the wire tube is pulled out vertically from the reel, including: When the wire tube deviates and drives the first steering wheel to rotate, the first signaling block rotates with the first steering wheel. During the rotation, if the first signaling block enters the sensing area of ​​the first signaling switch, the first signaling block and the first signaling switch generate a pulse signal; The first signaling switch sends a signal to the PLC, and the PLC controls the reel trolley to move laterally along the reel axis until the wire tube is separated from the first steering wheel, and the first steering wheel stops rotating. After a delay of t time, the reel trolley stops moving laterally, or when the wire tube contacts the second steering wheel to generate a pulse signal, the reel trolley stops moving laterally.

[0009] According to a wire tube unwinding control method, in step 300, the wire tube passes through the tube arranging device. If the wire tube deviates, the tube arranging device is triggered to generate a pulse signal, and the PLC receives the pulse signal. The PLC controls the reel to move laterally along the reel axis until the deviating of the wire tube is corrected to ensure that the wire tube is pulled out vertically from the reel, including: When the wire tube deviates and drives the second steering wheel to rotate, the second signal transmitting block rotates with the second steering wheel. During the rotation, if the second signal transmitting block enters the sensing area of ​​the second signal transmitting switch, the second signal transmitting block and the second signal transmitting switch generate a pulse signal; The second signaling switch sends a signal to the PLC, and the PLC controls the reel trolley to move laterally along the reel axis until the wire tube is separated from the second steering wheel, and the second steering wheel stops rotating. After a delay of t time, the reel trolley stops moving laterally, or when the wire tube contacts the first steering wheel to generate a pulse signal, the reel trolley stops moving laterally.

[0010] According to a wire tube unwinding control method, if neither the first steering wheel nor the second steering wheel generates a pulse signal, the wire tube continues to be pulled until the first steering wheel or the second steering wheel generates a pulse signal, and then unwinding production is performed according to the aforementioned steps.

[0011] In the technical solution of the embodiment of the present application, a pipe arranger capable of sliding in a direction parallel to the axial direction of the reel is provided on the outlet side of the reel, thereby eliminating the angle between the wire pipe and the pipe arranger and the guide wheel, so that the wire pipe is always pulled out in a state (close to) perpendicular to the axis of the reel. At the same time, it is ensured that no internal stress is generated when the wire pipe is unwound, and the outer surface of the wire pipe is not scratched. The manually operated pipe arranger is replaced, thereby reducing the labor intensity of the workers.

[0017] The following is an explanation of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0018] It should be noted that, in the present invention, the up, down, left and right in the figure are regarded as the up, down, left and right of the wire tube unwinding control method described in this specification.

[0019] The exemplary embodiments of the present invention are now described with reference to the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to disclose the present invention in detail and completely and to fully convey the scope of the present invention to those skilled in the art. The terms used in the exemplary embodiments shown in the accompanying drawings are not intended to limit the present invention. In the accompanying drawings, the same units / elements are marked with the same reference numerals.

[0020] Unless otherwise specified, the terms (including technical terms) used herein have the commonly understood meanings to those skilled in the art. In addition, it is understood that the terms defined in commonly used dictionaries should be understood to have the same meanings as those in the context of the relevant fields, and should not be understood as idealized or overly formal meanings.

[0021] This embodiment relates to a method for controlling the unwinding of a wire tube. Figure 2 , suitable for unwinding the wire tube 50 wound on the reel 20, from Figure 2 It can be seen that the reel 20 has a certain width and diameter, and the wire tubes 50 are wound around the reel 20 row by row.

[0022] When unwinding, the wire tube 50 detaches from the reel 20 row by row, that is, the position of the pulled wire tube 50 is constantly changing, while the reel 20 and the pipe arranger 30 in the prior art are fixed. This results in an angle being formed between the pulled wire tube 50 and the pipe arranger 30, and the angle is constantly changing, which eventually causes stress to be generated inside the pulled wire tube 50 and scratches the outer surface of the wire tube 50.

[0023] See also Figure 1 , the wire tube unwinding control method includes: Step 100 , along the pulling direction of the wire tube 50 , the reel 20 , the pipe arranger 30 , and the guide assembly 60 are arranged in sequence, wherein the wire tube 50 is wound around the reel 20 row by row.

[0024] The guide assembly 60 is located downstream of the pipe arranger 30. The guide assembly 60 is composed of two guide wheels. The wire pipe 50 passes through the two guide wheels. The gap between the two guide wheels can be adjusted (such as manual adjustment), that is, the gap can adapt to wire pipes 50 of different specifications to enter the production line smoothly.

[0025] In some embodiments, the guide assembly 60 may include a bracket on which two guide wheels are mounted. The two guide wheels can rotate around an axis, and in actual application, the wire pipe 50 should be kept in a horizontal state as much as possible. Therefore, the height of the bracket, the height of the pipe arranger 30 and the height of the reel 20 should be adjusted to make the wire pipe 50 in a horizontal state.

[0026] The reel 20 and the pipe rack 30 are arranged upstream of the guide assembly 60 along the pulling direction of the wire tube 50 , wherein the pipe rack 30 is located between the reel 20 and the guide assembly 60 .

[0027] Combination Figure 1 and Figure 2 It can be seen that the reel 20, the pipe arranger 30 and the guide assembly 60 are arranged in sequence along the pulling direction of the wire tube 50. That is, the pipe arranger 30 is arranged at the outlet side of the wire tube 50, and the wire tube 50 passes through the pipe arranger 30 to adjust the angle between the axial center line of the wire tube 50 and the reel 20.

[0028] The outlet side of the wire tube 50 refers to the direction in which the wire tube 50 is pulled away from the reel 20 .

[0029] Specifically, adjusting the angle between the wire tube 50 and the axial center line of the drum 20 means making the wire tube 50 as perpendicular to the axial center line of the drum 20 as possible. To this end, in this embodiment, the positions of both the drum 20 and the pipe arranger 30 are changeable.

[0030] In some embodiments, the reel 20 is mounted in the reel cart 10. Figure 2 As shown, the reel trolley 10 is movable. Figure 2 and Figure 3 The double-headed arrow shown is the moving direction of the reel trolley 10, that is, the reel trolley 10 can drive the reel 20 to move along its axial center line, the purpose of which is to continuously adjust the position of the pulled out wire tube 50 relative to the guide assembly 60 so that the wire tube 50 can smoothly enter the guide assembly 60.

[0031] In some embodiments, the bottom of the reel trolley 10 is equipped with wheels, which move laterally on the rollers on the foundation, that is, along the Figure 2 or Figure 3 Move in the direction indicated by the double-headed arrow. Figure 2 The arrow pointing to the left in the figure represents the rotation direction of the reel 20. Figure 3 The arrow with the middle point pointing to the right and marked with F represents the direction of the pulling force after the wire tube 50 is pulled.

[0032] In some embodiments, the pipe rack 30 includes a base plate 31, a steering wheel set, a signaling block and a signaling switch.

[0033] See also Figure 3The base plate 31 is slidably mounted on the base 40, and the sliding direction is parallel to the axial center line of the reel 20. In other words, the pipe arranging device 30 can slide along the base 40, and the sliding direction is consistent with the moving direction of the reel 20.

[0034] The steering wheel assembly is composed of two steering wheels mounted on a base plate 31. The wire tube 50 passes through the two steering wheels and drives the steering wheels to rotate. The two steering wheels are a first steering wheel 32 and a second steering wheel 35. The gap between the first steering wheel 32 and the second steering wheel 35 can be adjusted, and the gap can adapt to wire tubes 50 of different specifications to pass through the pipe rack 30 smoothly.

[0035] A signaling block is installed on each steering wheel, and a signaling switch is installed on the substrate 31 to sense the signaling block. Specifically, a first signaling block 33 is fixed on the first steering wheel 32, and a second signaling block 36 is fixed on the second steering wheel 35; a first signaling switch 34 is installed on the substrate 31 to sense the first signaling block 33, and a second signaling switch 37 is installed on the substrate 31 to sense the second signaling block 36.

[0036] The wire tube unwinding control method also includes a PLC, and the PLC connects the signaling switch and the winding drum trolley 10 through a signal.

[0037] Step 200 , pulling the wire tube 50 , and the wire tube 50 drives the reel 20 to rotate.

[0038] The wire tube 50 wound on the reel 20 is pulled and passes through the pipe rack 30 and the guide assembly 60 in sequence.

[0039] In step 300, the wire tube 50 passes through the tube arranger 30. If the wire tube 50 deviates, the tube arranger 30 is triggered to generate a pulse signal. The PLC receives the pulse signal and controls the reel 20 to move horizontally along the axis of the reel until the deviation of the wire tube 50 is corrected, ensuring that the wire tube 50 is pulled out vertically from the reel 20.

[0040] Specifically include: When the wire tube 50 deviates and drives the first steering wheel 32 to rotate, the first signal block 33 rotates with the first steering wheel 32. During the rotation, if the first signal block 33 enters the sensing area of ​​the first signal switch 34, the first signal block 33 and the first signal switch 34 generate a pulse signal.

[0041] The first signaling switch 34 sends a signal to the PLC, and the PLC controls the reel trolley 10 to move laterally along the reel axis until the wire tube 50 is separated from the first steering wheel 32, and the first steering wheel 32 stops rotating. After a delay of t time, the reel trolley 10 stops moving laterally, or when the wire tube 50 contacts the second steering wheel 35 to generate a pulse signal, the reel trolley 10 stops moving laterally.

[0042] Similarly, when the wire tube 50 deviates and drives the second steering wheel 35 to rotate, the second signal block 36 rotates with the second steering wheel 35. During the rotation, if the second signal block 36 enters the sensing area of ​​the second signal switch 37, the second signal block 36 and the second signal switch 37 generate a pulse signal.

[0043] The second signaling switch 37 sends a signal to the PLC, and the PLC controls the reel trolley 10 to move laterally along the reel axis until the wire tube 50 is separated from the second steering wheel 35, and the second steering wheel 35 stops rotating. After a delay of t time, the reel trolley 10 stops moving laterally, or when the wire tube 50 contacts the first steering wheel 32 to generate a pulse signal, the reel trolley 10 stops moving laterally.

[0044] That is, when the bobbin 50 is unwound, the steering wheel is driven by the bobbin 50 to passively rotate.

[0045] When the drum trolley 10 moves laterally, the position of the pulled wire pipe 50 also changes, that is, the lateral movement of the drum 20 drives the base plate 31 of the pipe arranger 30 to slide along the base 40 through the wire pipe 50, and the position of that also changes. In other words, the position of the guide assembly 60 is fixed, and the drum 20 and the pipe arranger 30 continuously adjust the pulled wire pipe 50 during the lateral movement, so that the pulled wire pipe 50 is always close to being perpendicular to the axial center line of the drum 20.

[0046] In some embodiments, the signaling block is connected or welded to the steering wheel.

[0047] In some embodiments, the signaling block is a metal block such as a bolt, and the signaling switch is a proximity switch.

[0048] During operation, the wire tube 50 is unwound under the action of traction, and the working process of the wire tube unwinding control method is as follows: (i) The wire tube 50 drives the first steering wheel 32 to rotate, and the first signal block 33 and the first signal switch 34 generate a pulse on-off signal. After receiving the signal, the PLC sends a downward movement command to the reel trolley 10. The reel trolley 10 moves the wire tube 50 laterally, and the wire tube 50 disengages from the first steering wheel 32. The first steering wheel 32 stops rotating and stops after a certain delay. It can also move until the wire tube 50 contacts the second steering wheel 35 and generates a pulse signal and stops. The above steps are repeated, and the wire tube 50 is in a constant working state.

[0049] (ii) The wire tube 50 drives the second steering wheel 35 to rotate, and the second signal block 36 and the second signal switch 37 generate a pulse on-off signal. After receiving the signal, the PLC sends an upward movement command to the winding trolley 10, and the winding trolley 10 moves the wire tube 50 horizontally, and the wire tube 50 is separated from the second steering wheel 35. The second steering wheel 35 stops rotating and stops after a certain delay. It can also stop after the wire tube 50 contacts the first steering wheel 32 and generates a pulse signal. The above steps are repeated, and the wire tube 50 is in a constant working state. (iii) If neither the first steering wheel 32 nor the second steering wheel 35 generates a pulse signal, the wire tube 50 continues to be pulled, that is, the wire tube 50 continues to work until the first steering wheel 32 or the second steering wheel 35 generates a pulse signal, and then the uncoiling production is carried out according to the working state (i) or the working state (ii).

[0050] The wire pipe unwinding control method provided in this embodiment is that when the wire pipe 50 is unwinding, the first steering wheel 32 or the second steering wheel 35 is passively rotated under the drive of the wire pipe 50, and the reel trolley 10 automatically moves laterally at any time to ensure that the wire pipe 50 smoothly enters the guide assembly 60, thereby avoiding the wire pipe 50 from generating a certain angle at the pipe arranger 30 and the guide wheel, ensuring that the wire pipe 50 does not generate internal stress when unwinding, and does not scratch the outer surface of the wire pipe, and replaces the manual operation of the pipe arranger, reducing the labor intensity of the workers.

[0051] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
