[0019] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0020] Figure 1 This is a schematic diagram of the intelligent pipe unloading and sorting production line provided in an embodiment of this application. The device includes a feeding mechanism, a first conveyor roller conveyor 4, a cutting mechanism 6, a truss assembly 7, a second conveyor roller conveyor 8, a first unloading mechanism, a processing roller conveyor, a beveling mechanism 20, a grinding mechanism 13, and a second unloading mechanism. The pipes to be processed are fed onto the first conveyor roller conveyor 4 via the feeding mechanism, and then conveyed to the cutting mechanism 6 via the first conveyor roller conveyor 4 to complete the pipe cutting. The cut pipes are then conveyed to the beveling mechanism 20 and the grinding mechanism 13 via the processing roller conveyor or the truss assembly 7 for further processing.

[0021] Specifically, the first conveyor roller 4 is used to convey the pipe fittings to be processed.

[0022] The feeding mechanism is located on one side of the first conveyor roller conveyor 4. (See also...) Figure 1The feeding mechanism includes a third material rack 1 fixedly mounted on one side of the first conveyor roller conveyor 4, a second baffle assembly 2 mounted at one end of the third material rack 1, and a second feeding assembly mounted between the first material rack 10 and the first conveyor roller conveyor 4. The third material rack 1 is used to hold the pipe fittings to be processed. The length direction of the third material rack 1 is perpendicular to the conveying direction of the first conveyor roller conveyor 4, and the end of the third material rack 1 adjacent to the first conveyor roller conveyor 4 is lower than the end of the third material rack 1 away from the first conveyor roller conveyor 4. The second baffle assembly 2 is mounted on the third material rack 1 at the end adjacent to the first conveyor roller conveyor 4. The second baffle assembly 2 includes a second baffle plate and a second telescopic hydraulic cylinder for driving the second baffle plate to move along the length direction of the third material rack 1 (i.e., perpendicular to the direction of the first conveyor roller conveyor 4). The upper end of the second baffle plate extends above the third material rack 1. The second feeding assembly is used to transport the pipe fittings on the third material rack 1 to the first conveyor roller conveyor 4. The second feeding assembly includes a second feeding tilting arm 3 and a fourth tilting hydraulic cylinder for driving the second feeding tilting arm 3 to tilt. One end of the second feeding boom 3 is hinged to the first conveying roller 4, and the other end of the second feeding boom 3 extends into the third material rack 1.

[0023] When the pipe to be processed is placed on the third rack 1, the pipe is parallel to the conveying direction of the first conveyor roller 4. At this time, the pipe will roll towards the end of the third rack 1 near the first conveyor roller 4 under the action of gravity, and stop after rolling to the second baffle. When loading is required, the second baffle is moved towards the side of the first conveyor roller 4 by the second telescopic cylinder, so that the pipe continues to move towards the side of the first conveyor roller 4 and moves the pipe to the second loading tilting arm 3. Then, the second loading tilting arm 3 is tilted by the fourth tilting cylinder, so that the pipe on the second loading tilting arm 3 can be conveyed to the first conveyor roller 4, completing the loading of the pipe.

[0024] The cutting mechanism 6 is located at the discharge end of the first conveyor roller conveyor 4 and is connected to the discharge end of the first conveyor roller conveyor 4. (See also...) Figure 1 The cutting mechanism 6 is located at the left end of the first conveyor roller conveyor 4. The cutting mechanism 6 includes a pipe clamping device for holding the pipe and a band saw for cutting the pipe. The first conveyor roller conveyor 4 conveys the pipe to the cutting mechanism 6, where it is clamped and fixed by the pipe clamping device, and then cut by the band saw. In this embodiment, the pipe clamping device includes a bench vise.

[0025] It should be noted that after the host computer transmits the cutting length information of the pipe to the controller, the controller controls the operation of the first conveyor roller 4 to move the pipe segment of the required length to the front end of the cutting blade, so that the cutting mechanism 6 can cut the pipe segment of a fixed length.

[0026] The second conveyor roller conveyor 8 is located on one side of the cutting mechanism 6, and its feed end is connected to the cutting mechanism 6 for conveying the cut pipe fittings. See also Figure 1 The second conveyor roller 8 is located at the right end of the cutting mechanism 6. The axis of the second conveyor roller 8 coincides with the axis of the first conveyor roller 4.

[0027] Truss assembly 7 is used for hoisting the cut pipe fittings. Truss assembly 7 is a three-axis intelligent truss, including two columns and a Y-axis guide rail fixedly mounted on the upper end of the columns, located directly above the cutting mechanism 6. A Y-axis moving component is mounted on the Y-axis guide rail. An X-axis guide rail is fixedly mounted on the Y-axis moving component, and an X-axis moving component is mounted on the X-axis guide rail. A Z-axis guide rail is fixedly mounted on the X-axis moving component, and a Z-axis moving component is mounted on the Z-axis guide rail. A clamping device for hoisting the pipe fittings is provided on the Z-axis moving component.

[0028] In this embodiment, the X-axis moving component, Y-axis moving component, and Z-axis moving component are all controlled by servo motors, which can drive the clamping device to move and be precisely positioned along the X, Y, and Z directions, thereby driving the pipe to move.

[0029] See Figure 1 On the left side of the cutting mechanism 6, there is also a buffer rack 22 and a rotary roller conveyor 5.

[0030] It should be noted that when the length of the cut pipe is less than the threshold, the truss assembly 7 hoists the cut pipe onto the buffer rack 22, and the truss assembly 7 moves the pipe to the subsequent processing mechanism for processing. When the length of the cut pipe is greater than or equal to the threshold, the cut pipe will be located on the second conveyor roller 8 and conveyed by the second conveyor roller 8 to the subsequent processing mechanism for processing.

[0031] In this embodiment, the threshold is 500 mm.

[0032] The processing roller conveyor is parallel to the second conveyor roller conveyor 8. (See also...) Figure 1 The beveling mechanism 20 is located at one end of the processing roller conveyor near the truss assembly 7, while the grinding mechanism 13 is located at the other end of the processing roller conveyor. The processing roller conveyor includes a third conveyor roller conveyor 15, a lifting rotary roller conveyor 18, and a fourth conveyor roller conveyor 19 connected sequentially, with the fourth conveyor roller conveyor 19 located near the beveling mechanism 20. During normal operation, the heights of the third conveyor roller conveyor 15, the lifting rotary roller conveyor 18, and the fourth conveyor roller conveyor 19 are all consistent.

[0033] See Figure 1The first unloading mechanism includes a first material rack 10 disposed between the second conveyor roller conveyor 8 and the processing roller conveyor; a first baffle assembly 12 disposed near one end of the first material rack 10 adjacent to the processing roller conveyor; a first unloading assembly disposed between the first material rack 10 and the second conveyor roller conveyor 8; and a first loading assembly disposed between the first material rack 10 and the processing roller conveyor. The length direction of the first material rack 10 is perpendicular to the conveying direction of the second conveyor roller conveyor 8. The end of the first material rack 10 adjacent to the second conveyor roller conveyor 8 is higher than the end of the first material rack 10 adjacent to the processing roller conveyor. The first baffle assembly 12 includes a first baffle plate and a first telescopic hydraulic cylinder for driving the first baffle plate to move perpendicular to the processing roller conveyor direction, with the upper end of the first baffle plate extending above the first material rack 10. The first unloading assembly is used to convey pipe fittings from the second conveyor roller conveyor 8 onto the first material rack 10. See also... Figure 1 The first unloading assembly includes a first unloading tilting arm 9 and a first tilting cylinder for driving the first unloading tilting arm 9. One end of the first unloading tilting arm 9 is hinged within the second conveying roller conveyor 8, and the other end extends into the first material rack 10. The first loading assembly is used to transport the pipes on the first material rack 10 onto the processing roller conveyor. The first loading assembly includes a first loading tilting arm 14 and a second tilting cylinder for driving the first loading tilting arm 14 to tilt. One end of the first loading tilting arm 14 is hinged within the processing roller conveyor, and the other end extends into the first material rack 10.

[0034] After the pipe fittings on the second conveyor roller conveyor 8 are conveyed above the first unloading tilting arm 9, the first tilting cylinder drives the first unloading tilting arm 9 to tilt towards the first material rack 10, thus conveying the pipe fittings onto the first material rack 10. When the pipe fittings are on the first material rack 10, they will roll towards the end of the third material rack 1 near the first conveyor roller conveyor 4 under their own gravity, and stop after rolling to the first baffle plate. Then, the first telescopic cylinder drives the first baffle plate to move towards the side of the processing roller conveyor, and moves the pipe fittings onto the first loading tilting arm 14. Subsequently, the second tilting cylinder drives the first loading tilting arm 14 to tilt towards the processing roller conveyor, thus conveying the pipe fittings on the first loading tilting arm 14 onto the processing roller conveyor.

[0035] It should be noted that one end of the first feeding boom 14 is hinged within the third conveyor roller conveyor 15. Therefore, the first feeding assembly feeds the pipe into the third conveyor roller conveyor 15. The pipe is then conveyed to the beveling mechanism 20 via the third conveyor roller conveyor 15, the lifting rotary roller conveyor 18, and the fourth conveyor roller conveyor 19, achieving beveling at one end of the pipe. The lifting rotary roller conveyor 18 can rotate the pipe on it 180°, thus achieving beveling at the other end of the pipe. Similarly, both ends of the pipe can be ground.

[0036] The beveling mechanism 20 includes a beveling machine and a first lifting platform for driving the beveling machine to move up and down. The grinding mechanism 13 includes a grinding machine and a second lifting platform for driving the grinding machine to move up and down. Before beveling and grinding, the beveling machine and the grinding machine need to be raised to the elevation of the pipe on the processing roller conveyor via the corresponding lifting platforms.

[0037] The second unloading mechanism is located on the side of the processing roller conveyor away from the second conveyor roller conveyor 8. (See also...) Figure 1 The second unloading mechanism includes a second material rack 17 disposed on the side of the processing roller conveyor away from the second conveying roller conveyor 8, and a second unloading assembly disposed between the second material rack 17 and the processing roller conveyor. The second material rack 17 is used to hold the processed finished pipe fittings. The second unloading assembly is used to transport the pipe fittings from the processing roller conveyor to the second material rack 17. The second unloading assembly includes a second unloading tilting arm 16 and a third tilting cylinder for driving the second unloading tilting arm 16 to tilt. One end of the second unloading tilting arm 16 is hinged inside the processing roller conveyor, and the other end of the second unloading tilting arm 16 extends into the second material rack 17.

[0038] After the pipe fittings on the processing roller conveyor have completed beveling and grinding, the processing roller conveyor transports the finished pipe fittings to the top of the second unloading tilting arm 16. Then, the second unloading tilting arm 16 is driven by the third tilting hydraulic cylinder to tilt towards the second material rack 17, so that the finished pipe fittings can be transported onto the second material rack 17.

[0039] In addition, a laser marking mechanism 21 for marking pipe fittings is also provided on one side of the cutting mechanism 6. After the cutting mechanism 6 clamps and fixes the pipe fitting, the laser marking mechanism 21 can automatically adjust its height according to the diameter of the pipe fitting. Then, the cylinder extends and retracts to push the spacer rod onto the pipe fitting for laser marking.

[0040] It should be noted that the first conveyor roller conveyor 4 is equipped with V-shaped conveyor rollers, and sprockets are mounted on the mounting shaft ends of the V-shaped conveyor rollers. All the upper sprockets of the V-shaped conveyor rollers are connected by a drive chain to provide power, so that the first conveyor roller conveyor 4 can drive the pipes on it to move smoothly. The structures of the second conveyor roller conveyor 8, the third conveyor roller conveyor 15, the fourth conveyor roller conveyor 19, and the lifting rotary roller conveyor 18 are all the same as those of the first conveyor roller conveyor 4.

[0041] See Figure 1 The hydraulic station 11 is used to provide power to all the hydraulic drive mechanisms mentioned above.

[0042] This application also provides a method for intelligent material unloading and sorting production in pipelines. The method includes the following steps: Step S101: The pipe fittings to be processed are hoisted and placed on the third material rack 1 in sequence.

[0043] Step S102: The pipes on the third material rack 1 are sequentially fed onto the first conveyor roller 4 by the feeding mechanism.

[0044] Step S103: Control the first conveyor roller 4 to run according to the cutting pipe length information transmitted by the host computer, transport the pipe to the cutting mechanism 6, and control the cutting mechanism 6 to clamp and fix the pipe. Then, laser mark the pipe by the laser marking mechanism 21.

[0045] Step S104: The cutting mechanism 6 cuts the pipe and determines whether the length of the cut pipe is less than the threshold. If yes, proceed to step S105; otherwise, proceed to step S106.

[0046] Step S105: The cut pipe is hoisted to the buffer rack 22 via the truss assembly 7. Then, the pipe on the buffer rack 22 is hoisted to the beveling mechanism 20 via the truss assembly 7. One end of the pipe is beveled. After beveling, the pipe is hoisted to the rotary roller conveyor 5 via the truss assembly 7. The pipe is rotated 180° via the rotary roller conveyor 5. Then, the pipe is hoisted to the beveling mechanism 20 via the truss assembly 7. The other end of the pipe is beveled. Then, the pipe is hoisted to the transfer trolley 23 via the truss assembly and transported to the grinding mechanism 13 for grinding.

[0047] It should be noted that in this embodiment, no truss assembly 7 is provided at the grinding mechanism 13. Therefore, after the transfer trolley 23 transports the pipe to the grinding mechanism 13, the operator needs to move the pipe to achieve the grinding process.

[0048] Step S106: The cut pipe is conveyed by the second conveyor roller 8, then the pipe is conveyed to the processing roller by the first unloading mechanism, and then the pipe is conveyed to the beveling mechanism 20 by the processing roller. One end of the pipe is beveled first, then the pipe is conveyed to the lifting rotary roller 18 by the fourth conveyor roller 19. The pipe is rotated 180° by the lifting rotary roller 18, and then the pipe is conveyed to the beveling mechanism 20 by the fourth conveyor roller 19 to bevele the other end of the pipe. Then the pipe is conveyed to the grinding mechanism 13 by the processing roller, and one end of the pipe is ground first. Then the pipe is conveyed to the rotary lifting roller by the second conveyor roller 8, and then the pipe is rotated 180° by the rotary lifting roller. Then the pipe is conveyed to the grinding mechanism 13 by the second conveyor roller 8 to grind the other end of the pipe.

[0049] Step S107: The finished workpiece is conveyed to the second material rack 17 by the second unloading mechanism.

[0050] Therefore, the technical solution of this application has set up a complete logistics and processing system for long and short pipe fittings respectively, realizing the automation of logistics transportation of pipe fittings of different lengths, and eliminating the need for operators to adjust the level of the pipe fittings, thus greatly improving production efficiency.

[0051] In addition to the above embodiments, the present invention may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
