[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0036] Embodiment 1

[0037] Referring to Figure 1 , Figure 1 A schematic diagram of a pipe material discharging method provided for an embodiment of the present application Figure 1 . As shown in Figure 1 , the present application provides a pipe material discharging method applied to a discharging whole pipe, which comprises an initial part pipe to be discharged; the discharging whole pipe is arranged in a preset coordinate system, which comprises a horizontal axis, a vertical axis and a vertical axis; the end line frame of the initial part pipe to be discharged is arranged at the origin position of the preset coordinate system. The pipe material discharging method provided by the present application comprises steps 101 to 105. In the present application, a schematic diagram of a pipe material discharging method will be combined as shown in Figure 2 .Figure 2 The steps are explained as follows:

[0038] In step 101, during the first time of the pipe material discharging process, the end tail line frame of the initial part-to-be-discharged pipe material is obtained as a comparison line frame at the current time;

[0039] As an example of the embodiment, before the pipe material discharging process is performed, it is determined whether the current pipe material discharging process to be performed is the first time of discharging. If it is the first time of pipe material discharging, it is indicated that there is no comparison line frame to be referred to in the current discharging whole pipe, and therefore, an initial part-to-be-discharged pipe material is discharged into the discharging whole pipe, and the end head line frame of the initial part-to-be-discharged pipe material is set at the origin position of the preset coordinate system, which includes a horizontal axis, a vertical axis and a vertical axis. For a specific implementable manner, see Figure 3 , Figure 3 A schematic diagram of a pipe material discharging method provided by an embodiment of the present application Figure 2 ; the initial part-to-be-discharged pipe material is discharged into the discharging whole pipe PA, and the tail end line frame thereof is recorded as Peline, which is taken as the comparison line frame at the current time;

[0040] In step 102, the pipe material discharging process is performed, the head end line frame of the part-to-be-discharged pipe material at the current time is taken as a comparison line frame at the current time, and the comparison line frame at the current time is obtained;

[0041] As an example of the embodiment, if the type of the part-to-be-discharged pipe material at the current time does not meet the rotation requirement of the preset vertical axis, the head end line frame of the part-to-be-discharged pipe material at the current time is taken as the comparison line frame at the current time. If the current pipe material discharging process is not the first time of pipe material discharging process, the tail end line frame of the part-to-be-discharged pipe material at the previous time is taken as the comparison line frame at the current time. If the type of the part-to-be-discharged pipe material at the current time meets the rotation requirement of the preset vertical axis, the part-to-be-discharged pipe material at the current time is rotated by a preset angle, and the tail end line frame of the part-to-be-discharged pipe material at the current time is taken as the comparison line frame at the current time.

[0042] Since the prior art simply arranges the pipe materials in a head-to-tail manner, the length of the discharging whole pipe cannot be maximally utilized, and therefore, in the embodiment of the present application, the shape of the pipe material is fully considered, and the pipe material meeting the requirement is rotated, and the two ends of the pipe material are arranged and determined. For a specific implementable manner, see Figure 4 and Figure 5 , Figure 4 A schematic diagram of a pipe material discharging method provided by an embodiment of the present application Figure 4 , Figure 5 A schematic diagram of a pipe material discharging method provided by an embodiment of the present application Figure 5 ; as Figure 4 and Figure 5As shown, the pipe laying process is executed, the pipe to be laid out at the current moment is placed, the end frame CSLine and the end frame CELine are obtained, and the type of the pipe to be laid out at the current moment is determined. For example, if it is a square pipe or a rectangular pipe, it can be rotated 180° around the vertical axis (equivalent to a preset angle); if it is a D-shaped pipe, it cannot be rotated 180° around the vertical axis. Therefore, in one example of the embodiment of the present invention, if the pipe to be laid out at the current moment is square or rectangular, both the end frame CSLine and the end frame CELine of the pipe to be laid out can be used as comparison frames, while if the pipe to be laid out at the current moment is D-shaped, only the end frame CSLine of the pipe can be used as comparison frames.

[0043] Step 103: Move the frame to be compared at the minimum position on the horizontal axis to the maximum position on the horizontal axis at the current moment to obtain the pipe arrangement position;

[0044] As an example of this embodiment, the coordinate values ​​of each point of the comparison frame at the current time on the horizontal axis are obtained; the values ​​of each point are compared one by one to obtain the minimum position on the horizontal axis; based on the minimum position on the horizontal axis, the pipe of the part to be arranged at the current time is moved to the maximum position on the horizontal axis of the comparison frame at the current time to obtain the pipe arrangement position.

[0045] To avoid failing to maximize the utilization of the entire pipe length during material feeding, this embodiment of the invention proposes an example of moving the comparison frame at its minimum position on the horizontal axis to its maximum position at the current moment. This ensures that the positions of the pipe to be fed and the already fed pipes are in a potential arrangement position. This technical solution allows for full utilization of the entire pipe length during material feeding, reducing waste and improving the reliability of the feeding results. For a specific implementation method, see [link to implementation details]. Figure 6 , Figure 6 A schematic diagram of a pipe material feeding method provided in one embodiment of the present invention. Figure 6 ;like Figure 6 As shown, the initial end frame PELine of the pipe to be arranged, which serves as the comparison frame, is regarded as a curve composed of several points. The coordinate position of each point on the horizontal axis is obtained, and the maximum value is taken. Similarly, the end frame CSLine or end frame CELine of the pipe to be arranged at the current moment, which serves as the comparison frame, can also be regarded as a curve composed of several points. The coordinate position of each point on the horizontal axis is obtained, and the minimum value is taken. The minimum value of the comparison frame is moved to the maximum value of the comparison frame to obtain the pipe arrangement position. It is worth mentioning that if the end frame CELine is not used as the comparison frame, this step can be ignored.

[0046] Step 104: Discretize the three-dimensional wireframe of the pipe arrangement position into several line segments, and expand the several line segments into a two-dimensional wireframe based on a preset reset starting point;

[0047] As an example of this embodiment, if the pipe to be arranged at the current moment is a round pipe, then the number of comparisons is obtained according to a preset step angle of rotation around the horizontal axis; based on the number of comparisons, the three-dimensional wireframe of the pipe arrangement position is rotated around the horizontal axis, and the rotation path is discretized into several line segments; a reset starting point is set at a position where the vertical axis is greater than a preset threshold and the vertical axis is equal to a preset threshold; based on the reset starting point, the several line segments are unfolded into a two-dimensional wireframe. If the pipe to be arranged at the current moment is not a round pipe, then the pipe arrangement position is rotated according to a preset pipe rotation comparison table, and the pipe arrangement position is unfolded into a two-dimensional wireframe.

[0048] Since the shapes of the tubing to be arranged vary, simply rotating the tubing may prevent it from being arranged into the entire discharge tube. To better utilize the length of the discharge tube and simplify the discharge process, this invention proposes to rotate the tubing along the horizontal axis by comparing the types of the tubing. Specifically, different comparison counts are assigned to different tubing types to reduce unnecessary and ineffective rotation comparisons, thus accelerating the discharge speed. This also simplifies the discharge process and improves the reliability of the discharge results. One possible implementation involves first determining the number of comparisons based on the tubing type and a preset step angle α. If the tubing to be arranged is currently circular, since the cross-sections of a circular tubing remain consistent regardless of rotation, the number of comparisons only needs to be calculated based on the preset step angle α. The specific formula is as follows:

[0049] n = 360.0 / a;

[0050] In the formula, n is the number of comparisons to be performed, and a is the preset step angle;

[0051] If the shape of the tubing to be arranged is other than the current shape, the corresponding comparison number will be retrieved according to the preset tubing rotation comparison table. Please refer to [link to relevant documentation] for details. Figure 7 , Figure 7 A schematic diagram of a pipe material feeding method provided in one embodiment of the present invention. Figure 7 ;like Figure 7 As shown in the figure, the "√" in the upper right corner indicates that the material can be placed into the tube after rotation. The step angle 'a' is set to 90°. When the square tube is rotated, there are four comparable points. Therefore, the number of comparisons for the square tube is recorded as 4. Similarly, when the rectangular tube and the D-shaped tube are rotated, the number of comparisons is 2 and 1 respectively. By considering the shape of the tube of the part to be arranged at the current moment, this can avoid multiple rotation comparison calculations that yield no results, speed up the material arrangement, and improve the reliability of the material arrangement results.

[0052] Current nesting algorithms are all three-dimensional, which are complex and computationally intensive. To simplify the nesting process, this invention proposes converting the three-dimensional calculation into a two-dimensional calculation. One specific implementation involves rotating the CSLine and CELine of the tubing to be nested at each current moment around the horizontal axis based on the number of comparisons required, and recording the rotation path. The rotation path (including the paths of PELine, CSLine, and CELine) is then discretized into several line segments. [The rest of the text is missing.] Figure 8 , Figure 8 A schematic diagram of a pipe material feeding method provided in one embodiment of the present invention. Figure 8 ;like Figure 8 As shown, the position where the vertical axis is greater than 0 (equivalent to a preset threshold) and the vertical axis is equal to 0 (equivalent to a preset threshold) is taken as the reset starting point. See [link / reference]. Figure 9 , Figure 9 A schematic diagram of a pipe material feeding method provided in one embodiment of the present invention. Figure 9 ;like Figure 9 As shown, based on the reset starting point, several line segments are unfolded from a three-dimensional wireframe into a two-dimensional wireframe.

[0053] Step 105: Based on the preset comparison algorithm, if the two-dimensional wireframe meets the common edge requirement, the pipe to be arranged at the current moment is arranged into the whole pipe of the material arrangement according to the two-dimensional wireframe, and the tail wireframe of the pipe to be arranged at the current moment is updated to the comparison wireframe of the next moment, and the pipe arrangement process ends.

[0054] As an example of the embodiment, based on a preset comparison algorithm, rays are drawn from each point of the current time comparison line frame along the horizontal axis to the points of the current time comparison line frame corresponding to the same vertical axis value, the rays intersect with the current time comparison line frame and the current time comparison line frame, and a plurality of corresponding intersection points are obtained; based on the plurality of corresponding intersection points, the distance values between the plurality of corresponding intersection points are calculated; if the distance values between the plurality of corresponding intersection points are equal, the two-dimensional line frame meets the common edge requirement, and the current time part pipe material is arranged into the material arrangement whole pipe according to the two-dimensional line frame, and the tail end line frame of the current time part pipe material is updated as the next time comparison line frame, and the pipe material arrangement process is ended. If the distance values between the plurality of corresponding intersection points are not equal, the sum of the distance values between the plurality of corresponding intersection points when the head end line frame of the current time part pipe material is taken as the current time comparison line frame is calculated to obtain a first distance value; the sum of the distance values between the plurality of corresponding intersection points when the tail end line frame of the current time part pipe material is taken as the current time comparison line frame is calculated to obtain a second distance value; if the first distance value is less than the second distance value, the current time part pipe material is arranged into the material arrangement whole pipe according to the two-dimensional line frame developed when the head end line frame of the current time part pipe material is taken as the current time comparison line frame, and the tail end line frame of the current time part pipe material is updated as the next time comparison line frame, and the pipe material arrangement process is ended; if the first distance value is greater than the second distance value, the current time part pipe material is arranged into the material arrangement whole pipe according to the two-dimensional line frame developed when the tail end line frame of the current time part pipe material is taken as the current time comparison line frame, and the head end line frame of the current time part pipe material is updated as the next time comparison line frame, and the pipe material arrangement process is ended.

[0055] In order to further guarantee the reliability of the pipe material arrangement result, the preset comparison algorithm is used to judge the common edge of the pipe material, and whether the two-dimensional line frame meets the common edge requirement is checked. The common edge requirement means that if two pipes can share a part of the boundary without generating additional waste, they should be arranged together preferentially. When the two-dimensional line frame meets the common edge condition, the current time part pipe material is arranged into the material arrangement whole pipe according to the two-dimensional line frame, and the comparison line frame of the next time is updated, thereby providing a comparison basis for the next pipe material arrangement process. When the two-dimensional line frame does not meet the common edge condition, the sum of the distance values between the plurality of corresponding intersection points is compared, and the optimal arrangement mode is selected. For a specific implementation, see Figure 10 , Figure 10 A pipe material arrangement method provided for an embodiment of the present application Figure 10 As shown in Figure 10As shown, PELine and CSLine, PELine and CEl ine are compared respectively by ray method (equivalent to preset comparison algorithm), and PELine, CSLine and CEl ine are regarded as curves composed of a plurality of points, for each point of PELine, a ray is made along the horizontal axis at the corresponding vertical axis height to CSLine and CEl ine, the ray intersects with PELine, CSLine and CEl ine, the intersection points are recorded as X(PELine), X(CSLine) and X(CELine), and the distances between the intersection points are recorded as ΔX1 and ΔX2, and the calculation formula is as follows:

[0056] ΔX1 = |X(PELine) - X(CSLine) |;

[0057] or ΔX2 = |X(PELine) - X(CELine) |;

[0059] As another example of the embodiment of the application, before the pipe material discharging process is performed, the following steps are included: judging whether the discharging whole pipe is full or not, if not, judging whether there is un-discharged pipe material or not, if yes, performing the pipe material discharging process, if the discharging whole pipe is full or there is no un-discharged pipe material, ending the pipe material discharging process.

[0060] The embodiment of the application provides a pipe material discharging method, by obtaining the current time comparison line frame and the current time to-be-compared line frame of the to-be-discharged pipe material of a part, and moving on the horizontal axis to ensure that the pipe material discharging is in a correct position in the discharging whole pipe, and to provide reliable data basis for subsequent processing, and then discretizing the three-dimensional line frame into a plurality of line segments and unfolding the three-dimensional line frame into a two-dimensional line frame, by converting the three-dimensional processing into two-dimensional processing, the processing flow is simplified, the data calculation amount is reduced, only two-dimensional data operation is considered and processed, in addition, in the process of converting the three-dimensional processing into the two-dimensional processing, a starting point is reset to ensure that there is a reference point in the dimension conversion process, and the reliability of data processing is ensured, and then the two-dimensional line frame is subjected to edge sharing judgment, which means that the pipe material needs to be as close as possible to the previous pipe material in the discharging process, so that the optimal scheme can be arranged, and the next time comparison line frame is updated to provide reliable data for the next cycle of pipe material discharging, through the above steps, reliable processing data is provided, the three-dimensional to two-dimensional processing method and the edge sharing requirement judgment not only simplify the discharging processing process, but also improve the reliability of the discharging result.
