Description

Technical Field

[0001] The present invention belongs to the technical field of automatic conveyor devices, and in particular relates to an automatic conveyor device for materials processed by laser. Background Art

[0002] Laser tube cutting machine is a professional equipment used to cut metal tubes. It uses high energy density laser beam to realize rapid cutting of tubes.

[0003] After cutting, existing laser tube cutting machines usually allow the tube to fall freely onto an inclined guide plate and then roll it into a collection frame. This makes the tube prone to bumps, wear, scratches, and other problems during free fall, affecting the quality of the tube. In addition, the cutting head of the laser tube cutting machine is usually at a higher height from the ground, so the tube is also cut at a higher position. When the factory needs to automatically transport the cut tube to a lower height from the ground, it also becomes a problem to be solved. Summary of the Invention

[0010] Furthermore, it also includes a pipe end grinding assembly arranged on one side close to the conveyor belt, and the pipe end grinding assembly includes a first grinding plate and a second grinding plate. The first grinding plate and the second grinding plate are respectively located on both sides of the conveyor turntable. When the pipe moves from the highest point to the lowest point of the conveyor turntable, the two ends of the pipe are in contact and friction with the first grinding plate and the second grinding plate respectively.

[0011] Furthermore, it also includes an inner gear ring installed on the frame, wherein an outer gear ring is connected to the outer periphery of one of the sleeves, and the outer gear ring and the inner gear ring are meshed with each other.

[0012] Furthermore, spiral grooves are provided on the inner diameters of the first rubber sleeve and the second rubber sleeve.

[0031] 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.

[0032] The following is combined with Figure 1 -Attached Figure 11 , describes in detail the technical solutions provided by each embodiment of the present invention.

[0033] Example 1: Reference Figures 1-11 An automatic conveyor device for laser-processed materials includes a rotating conveyor turntable 1, and further includes: a plurality of perforations 11 circumferentially provided on the conveyor turntable 1 for allowing a pipe 10 to be arranged across the conveyor turntable 1; a first rubber sleeve 122 and a second rubber sleeve 13 respectively provided on both sides of the conveyor turntable 1, the first rubber sleeve 122 and the second rubber sleeve 13 being used to support the cut pipe 10; a conveyor belt 4 provided on one side of the conveyor turntable 1, a plurality of limit bars 41 being provided circumferentially on the outer wall of the conveyor belt 4, and loading grooves 42 being formed between adjacent limit bars 41; a mechanical gripper assembly, wherein the pipe 10 is loaded at the highest point of the outer diameter of the conveyor turntable 1 and unloaded by the mechanical gripper assembly at the lowest point of the outer diameter of the conveyor turntable 1 and placed in the loading groove 42 of the conveyor belt 4;

[0034] The machine also includes a frame 2, a conveyor turntable 1 rotatably connected to the frame 2 via a bracket, and guide wheels 17 are rotatably connected to both sides of the outer periphery of the conveyor turntable 1 on the frame 2, with the outer periphery of the conveyor turntable 1 located between the two guide wheels 17;

[0035] The mechanical gripper assembly includes an electric slide 3, a mounting bracket 32 ​​is mounted on a slide 31 on the electric slide 3, a clamping cylinder 33 is arranged opposite to the mounting bracket 32, and a clamping rubber block 34 is mounted on the telescopic end of the clamping cylinder 33 to clamp the pipe 10 when the pipe 10 moves from the highest point to the lowest point of the conveying turntable 1;

[0036] Furthermore, the electric slide 3 may also use a cylinder to increase the reciprocating speed of the clamping cylinder 33, thereby increasing the feeding speed of the pipe 10;

[0037] Connecting frames 120 are installed on both sides of the conveying turntable 1. The connecting frames 120 are fixedly connected to the collar 12. The collar 12 is rotatably connected to the sleeve 121. The first rubber sleeve 122 and the second rubber sleeve 13 are respectively installed in the sleeve 121.

[0038] When in use, the device is installed on the side of the laser tube cutting machine where the tube is cut. When the laser tube cutting machine is cutting the tube, it automatically pushes the tube 10 forward to the required length, and then drives the tube 10 to rotate, so that the laser cutting head performs circumferential cutting on the tube 10.

[0039] Therefore, when the pipe 10 is pushed forward, the pipe 10 will sequentially penetrate into the first rubber sleeve 122, the through-hole 11, and the second rubber sleeve 13 located at the highest point of the outer diameter of the conveying turntable 1, so that the center of gravity of the cut pipe 10 is located on the conveying turntable 1. As a result, the pipe 10 can fall onto the conveying turntable 1 after being cut, and then, as the conveying turntable 1 rotates, the pipe 10 is gradually conveyed to the lowest point of the outer diameter of the conveying turntable 1.

[0040] When the pipe 10 is at the lowest point of the conveying turntable 1, the clamping cylinder 33 on the electric slide 3 moves toward the conveying turntable 1, clamps the pipe 10 with one end exposed outside the second rubber sleeve 13, and then returns the slide 31 on the electric slide 3. During the return process, the pipe 10 is pulled out from the first rubber sleeve 122, the perforation 11, and the second rubber sleeve 13. The pulled-out pipe 10 is located above the conveyor belt 4 and close to the outer wall of the conveyor belt 4. Then the clamping cylinder 33 releases the pipe 10, and the pipe 10 falls into the loading slot 42, thereby completing the transfer and transportation of the cut pipe 10.

[0041] It should be understood that the conveyor turntable 1 is driven by a motor, which is installed on one side of the conveyor turntable 1. The output end of the motor is connected to the fixed shaft of the conveyor turntable 1 through a synchronous belt or chain, and the motor drives the conveyor turntable 1 to rotate intermittently;

[0042] The conveyor belt 4 is connected to rollers, one of which is connected to another motor and driven to rotate intermittently. Therefore, after the mechanical gripper assembly places the pipe 10 on the conveyor belt 4, the conveyor belt 4 rotates and continues to transport the pipe 10 for transfer.

[0043] Therefore, this device limits the position of the tube 10 before cutting, i.e., through the first rubber sleeve 122, perforation 11, and second rubber sleeve 13 on the conveyor turntable 1. This prevents the tube 10 from free falling after being cut, i.e., from being bumped during cutting, thereby effectively protecting the tube 10. Furthermore, the conveyor turntable 1 can transfer tubes 10 located in a high position to a low position, thereby achieving orderly and sequential transfer of the cut tubes 10 to a low position during the laser tube cutting process, thereby facilitating subsequent processing operations.

[0044] It should be understood that when the diameter of the conveying turntable 1 is larger and the distance between the center of the through hole 11 and the center of the conveying turntable 1 is increased, it can further facilitate the conveying of the pipe 10 from a high place to a low place;

[0045] At the same time, the device can also wipe and clean the outer surface of the pipe 10 during the process of the pipe 10 passing through the first rubber sleeve 122 and the second rubber sleeve 13, thereby achieving the effect of cleaning the pipe 10 during the transfer and transportation of the pipe 10.

[0046] In one embodiment, referring to Figure 5 The conveyor belt 4 is arranged horizontally, and can be used to transport the cut pipe fittings 10 in a horizontal position, and then subsequent processing stations of the pipe fittings 10 can be set on both sides of the conveyor belt 4, which can effectively improve the processing efficiency of the enterprise;

[0047] In another embodiment, referring to Figure 6 The conveyor belt 4 is tilted downward at one end toward the bottom of the frame 2. The conveyor belt 4 is tilted downward at one end to further transport the cut pipe 10 to a lower position.

[0048] It should be understood that when the conveyor belt 4 is tilted, the height of the limiting strip 41 on the conveyor belt 4 will also increase accordingly to limit the pipe 10 and prevent the pipe 10 from rolling freely due to the tilt of the conveyor belt 4.

[0049] Example 2: Reference Figure 3-Figure 8, an automatic conveyor device for materials after laser processing, which is basically the same as Example 2, and further includes: a pipe end grinding assembly arranged on one side near the conveyor belt 4, the pipe end grinding assembly includes a first grinding plate 15 and a second grinding plate 16, and a bending guide portion 155 is provided at one end of the first grinding plate 15 and the second grinding plate 16 near the highest point of the conveying turntable 1, which makes it easier for the pipe 10 to enter between the first grinding plate 15 and the second grinding plate 16. The first grinding plate 15 and the second grinding plate 16 are respectively located on both sides of the conveying turntable 1. When the pipe 10 moves from the highest point to the lowest point of the conveying turntable 1, the two ends of the pipe 10 are in contact and friction with the first grinding plate 15 and the second grinding plate 16 respectively;

[0050] The inner diameters of the first rubber sleeve 122 and the second rubber sleeve 13 are smaller than the outer diameter of the pipe 10, and the inner diameters of the first rubber sleeve 122 and the second rubber sleeve 13 facing the laser pipe cutting machine are both chamfered, so that the pipe 10 is easily inserted and has a clamping force when it is sleeved on the first rubber sleeve 122 and the second rubber sleeve 13;

[0051] By arranging the first grinding plate 15 and the second grinding plate 16 on the conveying turntable 1, the device can grind both ends of the cut pipe 10 while the conveying turntable 1 is transferring the pipe 10 from a high place to a low place.

[0052] Specifically, when the pipe 10 is cut, the conveying turntable 1 rotates clockwise (in Figure 5 perspective as an example), the pipe 10 is moved closer to between the first polishing plate 15 and the second polishing plate 16, and both ends of the pipe 10 are respectively in contact with the first polishing plate 15 and the second polishing plate 16, thereby achieving polishing of both ends of the pipe 10.

[0053] Example 3: Reference Figure 7 、 Figure 9 An automatic conveyor device for laser-processed materials is substantially the same as that of Example 2, but further comprising an inner gear ring 141 mounted on a frame 2, so that the inner gear ring 141 does not rotate, an outer gear ring 14 is connected to the outer periphery of one sleeve 121, and the outer gear ring 14 and the inner gear ring 141 are meshed with each other;

[0054] The laser tube cutting machine pushes the tube fitting 10 into the first rubber sleeve 122 and the second rubber sleeve 13. When the laser tube cutting machine drives the tube fitting 10 to rotate clockwise, the tube fitting 10 rotates in the first rubber sleeve 122 and the second rubber sleeve 13.

[0055] When the conveying turntable 1 rotates, the outer gear ring 14 on the sleeve 121 engages with the inner gear ring 141 and rotates counterclockwise, thereby driving the pipe fitting 10 to rotate. The rotating pipe fitting 10, when in contact with the first grinding plate 15 and the second grinding plate 16, can better grind both ends of the pipe fitting 10.

[0056] In one embodiment, when used in conjunction with the pipe end grinding assembly, the angle of a single rotation of the conveyor turntable 1 can be adjusted, so that the rotation angle of the pipe 10 increases when the conveyor turntable 1 rotates once.

[0057] Example 4: Reference Figure 11 An automatic conveyor device for laser-processed materials is substantially the same as that of Example 3, with the further feature that a spiral groove 123 is formed on the inner diameter of the first rubber sleeve 122 and the second rubber sleeve 13, and the inner diameter of the first rubber sleeve 122 and the second rubber sleeve 13 is smaller than the outer diameter of the pipe 10;

[0058] When the laser tube cutting machine pushes the tube fitting 10 into the first rubber sleeve 122 and the second rubber sleeve 13, the laser tube cutting machine drives the tube fitting 10 to rotate, which drives the tube fitting 10 to rotate in the first rubber sleeve 122 and the second rubber sleeve 13. During the rotation, the spiral groove 123 engages the tube fitting 10, and then when the two ends of the tube fitting 10 are in contact with the first grinding plate 15 and the second grinding plate 16 for grinding, the tube fitting 10 can rotate normally.

[0059] Example 5: Reference Figure 7 、 Figure 8 , an automatic conveyor device for materials after laser processing, which is basically the same as Example 2, further includes: a pipe length self-checking component, which includes a mounting plate 151, a sliding rod 152 is slidably connected to the mounting plate 151, one end of the sliding rod 152 is fixedly connected to the first grinding plate 15, and a spring 153 is sleeved on the sliding rod 152 located between the first grinding plate 15 and the mounting plate 151. The two ends of the spring 153 are respectively fixedly connected to the first grinding plate 15 and the mounting plate 151. A distance sensor 154 is installed, and the second grinding plate 16 is installed on the frame 2 through a bracket; the length of the pipe 10 when the size is qualified is set to L. When the distance sensor 154 measures a length less than L and the measured pipe 10 moves to the first pushing cylinder 5 located on one side of the conveyor belt 4, the first pushing cylinder 5 pushes the pipe 10 away from the conveyor belt 4; when the distance sensor 154 measures a length greater than L and the measured pipe 10 moves to the second pushing cylinder 51 located on the other side of the conveyor belt 4, the first pushing cylinder 5 pushes the pipe 10 away from the conveyor belt 4;

[0060] When the conveying turntable 1 drives the pipe 10 to move between the first grinding plate 15 and the second grinding plate 16, the second grinding plate 16 is fixed, so the end of the pipe 10 is limited by the second grinding plate 16, and the end of the pipe 10 close to the first grinding plate 15 is pressed by the first grinding plate 15 connected to the spring 153, thereby improving the grinding effect on both ends of the pipe 10;

[0061] In addition, since the second grinding plate 16 is fixed, when the length of the pipe 10 is less than the required size, the distance between the first grinding plate 15 and the distance sensor 154 increases. Then, when the pipe 10 is transferred to the conveyor belt 4 and passes through the first pushing cylinder 5, the first pushing cylinder 5 pushes the pipe 10 off the conveyor belt 4 and falls into the "short length" defective product collection box;

[0062] When the length of the pipe 10 is longer than the required size, the first grinding plate 15 will be closer to the distance sensor 154. Then, when the pipe 10 is conveyed to the conveyor belt 4, it is pushed away to the "long-short-long" unqualified product collection box when passing through the second pushing cylinder 51.

[0063] Before cutting the tube 10, the present invention uses the first rubber sleeve 122, perforations 11, and second rubber sleeve 13 on the conveyor turntable 1 to limit the position of the tube 10. This prevents the tube 10 from free falling after being cut, that is, it will not collide during cutting, thereby effectively protecting the tube 10. Secondly, the conveyor turntable 1 can transfer tubes 10 in a high position to a low position, thereby achieving orderly and sequential transfer of the cut tubes 10 to a low position during the laser tube cutting process, thereby facilitating subsequent processing operations.

[0064] Moreover, the device can also automatically grind both ends of the pipe 10 during the transportation and transfer process of the pipe 10, and can also use the pipe end grinding component to automatically detect the length of the pipe 10 after cutting, thereby effectively improving the working efficiency of laser pipe cutting and the control of pipe cutting quality.

[0065] 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 the present invention can make slight changes or modifications to equivalent embodiments using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
