Description

Technical Field

[0001] The present invention belongs to the technical field of pipe processing, and in particular relates to an integrated control system and method for pipe bending processing. Background Art

[0002] Existing technologies rely on manual sorting, recording, transportation, and storage management for pipe bending. This management and production method not only wastes significant labor, but also reduces the overall efficiency of the pipe bending process. More importantly, during these manual sorting, recording, transportation, and storage processes, human errors can occur, resulting in discrepancies between recorded results and actual production results. This also makes it impossible to effectively trace the entire pipe bending process, further wasting labor and costs.

[0003] In view of this, the present invention is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an integrated control system and method for pipe bending processing.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: an integrated control system for pipe bending processing, including a straight pipe transmission device and a bent pipe transmission device;

[0007] The centralized control system is used to control the sorting mechanism to sort straight pipes of different specifications to the corresponding pipe bending processing components;

[0008] The pipe bending processing assembly will bend the straight pipe and transport the processed bent pipe to the pipe bending transmission device, and the pipe bending transmission device will transport the bent pipe to the set position.

[0009] Furthermore, the curved pipe transmission device and the straight pipe transmission device are arranged in a stacked manner, wherein the straight pipe transmission device is located below the curved pipe transmission device.

[0010] Furthermore, a buffer rack is provided between the straight pipe transmission device and each of the bent pipe processing components;

[0011] The buffer material rack is used to store the straight pipes to be processed, and a code reading device is provided on the buffer material rack;

[0012] The code reading device is used to read the two-dimensional code on the straight pipe and transmit the read signal to the centralized control system.

[0013] Furthermore, the bent pipe transmission device includes a robotic arm and a pipe bender;

[0014] The robotic arm is arranged on the tooling platform, and the robotic arm moves on the tooling platform;

[0015] The robotic arm is used to transfer the straight pipes on the buffer rack to the pipe bender, and to transfer the bent pipes processed by the pipe bender to the bent pipe transmission device.

[0016] Furthermore, the centralized control system is used to control the robotic arm and the pipe bending machine.

[0017] The present application also provides a pipe bending processing integrated control method, including a pipe bending processing integrated control system, including the following operating steps:

[0018] S1. The centralized control system reads the QR code information of the direct pipe;

[0019] S2. The centralized control system controls the sorting mechanism to transport the corresponding straight tube to the corresponding buffer rack;

[0020] S3. A code reading device is provided on the buffer material rack to scan the straight tube QR code and send the scanned code information to the centralized control system;

[0021] S4. The centralized control system controls the corresponding robotic arm according to the straight pipe QR code information to transfer the straight pipe on the buffer rack to the pipe bending machine for bending;

[0022] S5. After the pipe bending machine completes the pipe bending process, the centralized control system controls the robotic arm to transfer the bent pipe to the pipe bending transmission line.

[0023] Furthermore, in step S1, during the process of processing the straight tubes, the centralized control system reads the QR codes of the straight tubes in sequence, and sets the control program of the sorting mechanism according to the QR code information of the straight tubes.

[0024] Furthermore, in step S3, the centralized control system controls the robotic arm to move to the position corresponding to the cache rack on the tooling platform according to the QR code information of the straight pipe; and the robotic arm transports the straight pipe corresponding to the QR code information to the pipe bending machine. After the centralized control system controls the robotic arm to complete the loading operation of the pipe bending machine, it controls the pipe bending machine to perform the pipe bending operation.

[0025] Furthermore, in step S3, when the code reading device fails to obtain the QR code or the obtained QR code is different from the QR code corresponding to the control program of the sorting mechanism in the centralized control system, an alarm process is performed.

[0026] Furthermore, in step S5, the centralized control system controls the robotic arm to grab the bent pipe processed by the pipe bender, and controls the robotic arm to move on the tooling platform to the side close to the bent pipe transmission device. The robotic arm places the bent pipe on the bent pipe conveying device, and the bent pipe conveying device conveys the bent pipe to the set position.

[0027] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

Therefore, they cannot be understood as limiting the present invention.

[0038] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0039] like Figure 1 As shown, the integrated control system for pipe bending processing of the present invention includes a straight pipe transmission device 1 and a bent pipe transmission device 2;

[0040] The straight tube transmission device 1 may be provided with a plurality of bending tube processing components 4 on both sides along the transport direction, and the straight tube transmission device 1 is provided with a sorting mechanism corresponding to the plurality of bending tube processing components 4 one by one;

[0041] The sorting mechanism is used to sort the straight pipes transported by the straight pipe transmission device 1 to the corresponding bending pipe processing components 4;

[0042] The plurality of pipe bending processing assemblies 4 transport the processed pipe bends to the pipe bending transmission device 2, and the pipe bending transmission device 2 transports the pipe bends to the set position.

[0043] In existing technologies, the production process for bent pipes still relies on manual sorting, loading and unloading, and transportation. This repetitive work can easily lead to errors in the production and management process. Repeated sorting, transportation, and storage processes also lead to significant labor waste, and the efficiency of pipe production has not been improved. Furthermore, after the pipes have gone through multiple processes such as sorting and production, if errors in the pipe data are present, the traceability of the pipe data is poor due to the possibility of errors in the sorting, recording, and transportation processes.

[0044] In order to solve the above technical problems, an embodiment of the present application provides an integrated control system for pipe bending processing, by providing a sorting mechanism corresponding one-to-one to multiple pipe bending processing components 4 on the straight pipe transmission device 1, and connecting the sorting mechanism to the centralized control system 5, so that the centralized control system 5 can control the sorting mechanism to transport straight pipes of different specifications to different pipe bending processing components 4 respectively, and multiple pipe bending processing components 4 can respectively process straight pipes of specific specifications, thereby improving the efficiency of pipe bending production.

[0045] Optionally, the bend pipe transmission device 2 and the straight pipe transmission device 1 are stacked, wherein the straight pipe transmission device 1 is located below the bend pipe transmission device 2. In order to avoid the site occupied by the bend pipe processing being too large, the bend pipe transmission device 2 and the straight pipe transmission device 1 are stacked, which can effectively reduce the floor space. At the same time, multiple bend pipe processing components 4 are arranged adjacent to the straight pipe transmission device 1. Therefore, it can be seen that multiple bend pipe components and the bend pipe transmission device 2 can also be arranged adjacent to each other, thereby greatly reducing the overall occupied area of ​​the bend pipe processing integrated control system. It can also relatively shorten the transportation time of each straight pipe or bend pipe between each device, thereby improving the production efficiency of the bend pipe.

[0046] Optionally, a buffer rack 3 is provided between the straight pipe transmission device 1 and each bend pipe processing assembly 4;

[0047] The buffer rack 3 is used to store the support tubes to be processed, and a code reading device 301 is provided on the buffer rack 3;

[0048] The code reading device 301 is used to read the two-dimensional code on the straight tube.

[0049] In order to further improve the traceability of the bent pipe manufacturing process, a corresponding QR code may be provided on the straight pipe, and a code reading device 301 for reading the straight pipe QR code is provided on the buffer rack 3. The code reading device 301 is used to read the QR code on the straight pipe and transmit the read signal to the centralized control system 5; further, the centralized control system 5 has pre-stored a sorting mechanism control program set according to the straight pipe QR code signal, so that the centralized control system 5 can orderly classify the specifications and models of the straight pipes on each buffer rack 3. Based on this, the code reading device 301 sends the read straight pipe QR code signal to the centralized control system 5, so that the centralized control system 5 can compare it with the pre-set classification model and perform repeated verification to ensure that the sorting and processing sequence of each straight pipe can be carried out in an orderly manner.

[0050] Furthermore, the centralized control system 5 can also set the processing sequence based on the processing time of each pipe bending machine 403, and control the bending sequence of each pipe bending machine 403 based on actual production needs, which can further improve the processing efficiency of the pipe bending.

[0051] Preferably, since the straight pipe transmission device 1 and the bent pipe transmission device 2 are arranged in a stacked structure, the tray on the buffer rack 3 for receiving straight pipes can be designed as a retractable circulation structure, so that the buffer rack 3 can receive more straight pipes. It should be further explained that the robot arm 402 is used to transfer the straight pipes on the buffer rack 3 to the pipe bender 403, and the bent pipes processed by the pipe bender 403 need to be transferred to the bent pipe transmission device 2. In order to further improve the operation efficiency of the robot arm 402, the bent pipe transmission device 2, the tooling platform 401 equipped with the robot arm 402, and the pipe bender 403 can all be set at the same height, and the tray on the buffer rack 3 can be raised to the same height as the robot arm 402, so that the robot arm 402 can grab the straight pipes while facilitating the robot arm 402 to transfer the processed bent pipes to the bent pipe transmission device 2. This can reduce the problem of multiple height adjustments of the robot arm 402 and simplify the movement program of the robot arm 402.

[0052] Optionally, the pipe bending transmission device 2 includes a robotic arm 402 and a pipe bending machine 403; the robotic arm 402 is arranged on the tooling platform 401, and the robotic arm 402 can move on the tooling platform 401; it should be noted here that the movement of the robotic arm 402 on the tooling platform 401 does not refer to the movement of the robotic arm 402, but the robotic arm 402 as a whole including the base reciprocating along the extension direction of the tooling platform 401.

[0053] Furthermore, the buffer rack 3 is protruding from either side of the straight pipe transmission device 1. When the tooling platform 401 equipped with a robotic arm 402 and the pipe bender 403 are arranged in sequence, the robotic arm 402 can transfer the straight pipes on the buffer rack 3 to the pipe bender 403. However, when transferring the bent pipes processed by the pipe bender 403 to the bent pipe transmission device 2, the distance between the robotic arm 402 and the bent pipe transmission device 2 is large, making it inconvenient for the robotic arm 402 to operate. To this end, the tooling platform 401 equipped with the robotic arm 402 and the pipe bender 403 are tilted relative to the bent pipe transmission device 2, so that the two ends of the tooling platform 401 can be simultaneously close to the buffer rack 3 and the bent pipe transmission device 2, thereby ensuring the working efficiency of the robotic arm 402 and reducing operational errors of the robotic arm 402.

[0054] Optionally, the centralized control system 5 is used to control the robotic arm 402 and the pipe bender 403. During the initial straight pipe blanking and coding process, the centralized control system 5 can set the working procedures of each pipe bending processing component 4: for example, according to the different straight pipe diameters, the straight pipe conveying order on the straight pipe transmission device 1 is sorted, and then combined with the straight pipe information stored on the buffer material rack 3, the pipe bending processing order of each pipe bending processing component 4 can be sorted. Combined with the pipe bending information required in subsequent processes, the centralized control system 5 can sort the working order of the robotic arm 402 and the pipe bender 403 of each pipe bending processing component 4, so that the order of the pipes conveyed by the pipe bending transmission device 2 can be grouped, which is convenient for reducing the sorting process in subsequent processes and improving the production and utilization efficiency of pipe bends.

[0055] refer to Figure 2 , an embodiment of the present application further provides a pipe bending processing integrated control method, comprising the following steps:

[0056] S1, the centralized control system 5 reads the QR code information of the direct pipe;

[0057] S2, the centralized control system 5 controls the sorting mechanism to transport the corresponding straight tube to the corresponding buffer rack 3;

[0058] S3, a code reading device 301 is provided on the buffer material rack 3, which scans the straight tube QR code and sends the scanned code information to the centralized control system 5;

[0059] S4. The centralized control system 5 controls the corresponding robotic arm 402 according to the straight pipe QR code information to transfer the straight pipe on the buffer rack 3 to the pipe bending machine 403 for bending.

[0060] S5. After the pipe bending machine 403 completes the pipe bending process, the centralized control system 5 controls the robotic arm 402 to transfer the bent pipe to the pipe bending transmission line.

[0061] Furthermore, in step S1, during the process of processing the straight tubes, the centralized control system 5 reads the QR codes of the straight tubes in sequence, and sets the control program of the sorting mechanism according to the QR code information of the straight tubes.

[0062] Step S3 also includes: S3.1, the centralized control system 5 controls the robotic arm 402 to move to the corresponding cache rack 3 position on the tooling platform 401 according to the QR code information of the straight pipe; and the robotic arm 402 transports the straight pipe corresponding to the QR code information to the pipe bending machine 403. After the centralized control system 5 controls the robotic arm 402 to complete the loading operation of the pipe bending machine 403, it controls the pipe bending machine 403 to perform the pipe bending processing operation.

[0063] S3.2. When the code reading device 301 fails to obtain the QR code or the obtained QR code is different from the corresponding QR code information preset in the centralized control system 5, an alarm process is performed.

[0064] In step S5, the centralized control system 5 controls the robot arm 402 to grab the bent pipe processed by the pipe bender 403, and controls the robot arm 402 to move on the tooling platform 401 to the side close to the bent pipe transmission device 2. The robot arm 402 places the bent pipe on the bent pipe conveying device, and the bent pipe conveying device conveys the bent pipe to the set position.

[0065] Through the above scheme, in the embodiment of the present application, the pipe is cut into straight pipes of fixed length after being cut. The straight pipe is transferred to the straight pipe transmission device 1 after coding. The straight pipe transmission device 1 transfers the straight pipe to the corresponding pipe bending machine 403 workstation according to the instructions of the centralized control system 5, and the straight pipe is sorted to the corresponding straight pipe buffer rack 3 by the sorting mechanism provided on the straight pipe transmission line. The straight pipe buffer rack 3 can transfer the straight pipe to the set position, and the code reading device 301 scans the QR code on the pipeline to obtain the pipeline QR code information. When the pipeline QR code cannot be obtained for a long time or the QR code is obtained incorrectly, an alarm is generated. The code reading device 301 feeds back the obtained pipeline QR code information to the centralized control system 5. After the centralized control system 5 verifies that it is correct, it passes the pipe bending processing program to the pipe bending machine 403, and calls the robotic arm 402 to grab the straight pipe to load the pipe bending machine 403. After the loading is completed, the robotic arm 402 returns to the set position. The code reading device 301 feeds back the acquired pipeline QR code information to the centralized control system 5. After the centralized control system 5 verifies that the pipeline specifications have changed, it issues an alarm to remind the user to replace the pipe bending mold. After the mold is replaced, the above process continues.

[0066] The pipe bender 403 bends the pipe according to the received bending program. Upon completion, the bender 403 sends a signal indicating completion to the centralized control system 5, which then activates the robotic arm 402 to grab and unload the pipe. Following the instructions from the centralized control system 5, the robotic arm 402 adjusts the position and angle of the fixture, grabs the pipe from the bender 403, and unloads it onto the pipe transfer line. The robotic arm 402 then sends a signal indicating completion to the centralized control system 5. The centralized control system 5 then activates the pipe transfer line to transfer the pipe to the designated location.

[0067] Through the above solution, all-round tracking and detection of the straight pipe processing program can be achieved, and all processes can be automated, which greatly reduces the required manpower. Only maintenance personnel are required to maintain the system or deal with emergencies that trigger alarm signals.

[0068] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments of equivalent changes using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention.
